"My buddies said that menstruation is awful. But at the camp, we learned it's a desirable and natural procedure for ladies. I'll cross my lower back and tell my friends they have been incorrect," stated Vijay, a class eight pupil. These are the phrases of Vijay, a category eight student, who attended Fireflies, a camp organized using VOICE Four Girls, an NGO that has been running with youngsters in schools under the Telangana Social Welfare Residential Educational Institutions Society (TSWREIS) and Telangana Tribal Welfare Residential Educational Institutions Society (TTWREIS). The societies run residential academic institutions (class five to diploma stage) in the state below the Telangana Ministry of Scheduled Caste Development and the Telangana Ministry of Tribal Welfare.
Recently, they have been doing something quite clean – with the help of VOICE 4 Girls, they may be coaching boys in these schools about menstruation, intellectual health, consent, and more The impact of equality is meditated in Vijay's phrases. It's 2019, but in lots of colleges, sexuality training, if it exists inside the first area, is still restricted to a one-off session wherein women are talked to approximate menstruation.
Though the lads are excluded from this dialogue, menstruation turns into all but an open mystery, regularly becoming a remembrance of disgrace for the girls. To cope with this, VOICE 4 Girls organized 'Fireflies', a camp for boys to speak about problems like consent, reproductive fitness, intellectual fitness, and so on.] Vijay's video was shared on Twitter with the aid of RS Praveen Kumar, secretary of TSWREIS as well as TTWREIS, who stressed that empowerment of ladies couldn't be completed without instructing men about gender and empathy too.
What happens at the camps?
Firefly is an 8-day camp held from May 6 to 13, engaged with 743 adolescent boys from Telangana Social Welfare Schools from around ninety-four locations. The camps have been performed simultaneously in four specific places across Telangana: Husnabad, Tirumalayapalem, Miryalaguda, and Boinapally.
VOICE 4 Girls designs its content material based tn primary research with students. Faiza Khan, who created the curriculum for the lads' camp, says that the material is rooted inside the boys' social context and is repeatedly revised primarily based on how college students reply. Further, while it's far in the main in English, Telugu versions of the books are also to be had. To de-jargonize ideas, terms from the nearby language are used, too.
The camp counselors are typically young university students who are meticulously skilled in class management and use real-life stories to explain difficult concepts. Female counselors train at the women's and m, ale counselors at the boys' camps. Students are given curated books, but mastery isn't restricted to the page. Subjects and thoughts are taught creatively, using skits, games, and sports.
For example, to provoke a verbal exchange around consent, counselors facilitate a pastime where college students split into agencies and give you a skit about making and serving tea. The round conversation consent begins by facilitating a discussion about the soreness of having someone impose a drink when they do not want it, after which movements move on to things like giving hugs and organizing bodily touch. Boys are encouraged to empathize with women's stories in such eventualities.
Another activity they undertook to provide an explanation for the idea of sufferers blaming boys changed into one wherein they were requested to stay lifestyles in the day of a female, Rani. "They sincerely liked this hobby and got towels to dress up as Rani. Then, they are made to play act instances from her existence wherein she faces violence and is blamed for it. The roleplay with the boy's aid became notable," Faiza says. While debriefing after the hobby, Faiza says the men felt empathetic towards girls and skilled a leap forward. "They stated that they had never realized women went via these items," she says.
A secure area
Laasya says that the studying curve with the Telangana Social Welfare Schools students has been high as they address topics that aren't talked about or are taboo. So, students are curious to recognize more. The camp has also become a place for reflection and introspection for these young boys. For instance, a boy came here to camp firmly believing that ladies were wrong to wear brief skirts. "The counselor and other kids attempted to cope with him, but he wouldn't budge. However, his outlook changed by day eight. He got here and advised his counselor that ladies have the right to wear what they want and must not be judged for it.
The transition became quite heartening," shares Faiza. While those effects are heartening, Praveen Kumar says it's too early to talk about the long-term period effect. "We are hoping those boys will become more sensitive towards ladies, especially their reviews and biological strategies going ahead. We desire that the youngsters could share what they've found out with their buddies and mot, mothers, and her. Fathers plan to continue conducting focus applications on a larger scale in the future."
Why communicate with boys?
VOICE fFourGirls conducts pastime-based camps in government and inexpensive private schools for 12 to fifteen-year-olds, addressing subjects like fitness, protection, and future planning while simultaneously constructing English speak-abilities and important thinking. It has, in particular, worked with adolescent girls from Telangana Social Welfare Schools for the past five years. However, while carrying out co-ed workshops in the beyond, camp counselors felt the need to speak to boys about ladies' experiences, says Anusha Bharadwaj,
VOICE 4 Girls Executive Director.
"Fireflies become the primary phase of the lads' software. It brought them to numerous subjects, which include intellectual health, reproductive fitness, violence, rights, the role of media, and so on. BInthis, ton second section, Supernova, will talk aaboutdecoaboutnder, recognizing socially built masculinity, and gender-primarily based violence, amongst different subjects. TherSupernova also has management aspectshing them to be network leaders," Laasya Reddy, a Content and Communications Officer at VOICE 4 Girls, tells TNM. "We wish to cause them to imbibe senators who can take steps towards creating an engender-identically."
Praveen Kumar says that the workshops were a way to encourage young boys to become sensitive, empathetic, and accountable: "Boys:ften convey stereotypical notions around what women can or can't do. These boys will develop as much as to be guys, husbands, and people. We want them to be better prepared to handle their relationships with women around them. They must be capable of making manner for range anyplace they end up as adults," he asserts. |

Item Open Access Barriers and Facilitators to Adoption of Genomic Services for Colorectal Care within the Veterans Health Administration.(J Pers Med, 2016-04-28) Sperber, Nina R; Andrews, Sara M; Voils, Corrine I; Green, Gregory L; Provenzale, Dawn; Knight, SaraWe examined facilitators and barriers to adoption of genomic services for colorectal care, one of the first genomic medicine applications, within the Veterans Health Administration to shed light on areas for practice change. We conducted semi-structured interviews with 58 clinicians to understand use of the following genomic services for colorectal care: family health history documentation, molecular and genetic testing, and genetic counseling. Data collection and analysis were informed by two conceptual frameworks, the Greenhalgh Diffusion of Innovation and Andersen Behavioral Model, to allow for concurrent examination of both access and innovation factors. Specialists were more likely than primary care clinicians to obtain family history to investigate hereditary colorectal cancer (CRC), but with limited detail; clinicians suggested templates to facilitate retrieval and documentation of family history according to guidelines. Clinicians identified advantage of molecular tumor analysis prior to genetic testing, but tumor testing was infrequently used due to perceived low disease burden. Support from genetic counselors was regarded as facilitative for considering hereditary basis of CRC diagnosis, but there was variability in awareness of and access to this expertise. Our data suggest the need for tools and policies to establish and disseminate well-defined processes for accessing services and adhering to guidelines.Item Open Access Challenges and strategies for implementing genomic services in diverse settings: experiences from the Implementing GeNomics In pracTicE (IGNITE) network.(BMC Med Genomics, 2017-05-22) Sperber, Nina R; Carpenter, Janet S; Cavallari, Larisa H; J Damschroder, Laura; Cooper-DeHoff, Rhonda M; Denny, Joshua C; Ginsburg, Geoffrey S; Guan, Yue; Horowitz, Carol R; Levy, Kenneth D; Levy, Mia A; Madden, Ebony B; Matheny, Michael E; Pollin, Toni I; Pratt, Victoria M; Rosenman, Marc; Voils, Corrine I; W Weitzel, Kristen; Wilke, Russell A; Ryanne Wu, R; Orlando, Lori ABACKGROUND: To realize potential public health benefits from genetic and genomic innovations, understanding how best to implement the innovations into clinical care is important. The objective of this study was to synthesize data on challenges identified by six diverse projects that are part of a National Human Genome Research Institute (NHGRI)-funded network focused on implementing genomics into practice and strategies to overcome these challenges. METHODS: We used a multiple-case study approach with each project considered as a case and qualitative methods to elicit and describe themes related to implementation challenges and strategies. We describe challenges and strategies in an implementation framework and typology to enable consistent definitions and cross-case comparisons. Strategies were linked to challenges based on expert review and shared themes. RESULTS: Three challenges were identified by all six projects, and strategies to address these challenges varied across the projects. One common challenge was to increase the relative priority of integrating genomics within the health system electronic health record (EHR). Four projects used data warehousing techniques to accomplish the integration. The second common challenge was to strengthen clinicians' knowledge and beliefs about genomic medicine. To overcome this challenge, all projects developed educational materials and conducted meetings and outreach focused on genomic education for clinicians. The third challenge was engaging patients in the genomic medicine projects. Strategies to overcome this challenge included use of mass media to spread the word, actively involving patients in implementation (e.g., a patient advisory board), and preparing patients to be active participants in their healthcare decisions. CONCLUSIONS: This is the first collaborative evaluation focusing on the description of genomic medicine innovations implemented in multiple real-world clinical settings. Findings suggest that strategies to facilitate integration of genomic data within existing EHRs and educate stakeholders about the value of genomic services are considered important for effective implementation. Future work could build on these findings to evaluate which strategies are optimal under what conditions. This information will be useful for guiding translation of discoveries to clinical care, which, in turn, can provide data to inform continual improvement of genomic innovations and their applications.Item Open Access COVID-19 vaccination intention and activation among health care system employees: A mixed methods study.(Vaccine, 2022-08) Vasudevan, Lavanya; Bruening, Rebecca; Hung, Anna; Woolson, Sandra; Brown, Adrian; Hastings, Susan N; Linton, Tammy; Embree, Genevieve; Hostler, Christopher J; Mahanna, Elizabeth; Okeke, Nwora Lance; Bosworth, Hayden; Sperber, Nina RBackground
Achieving high COVID-19 vaccination rates among employees is necessary to prevent outbreaks in health care settings. The goal of the study was to produce actionable and timely evidence about factors underlying the intention and decisions to obtain the COVID-19 vaccine by employees.Methods
The study was conducted from December 2020 - May 2021 with employees from a VA health care system in Southeastern US. The study used a convergent mixed methods design comprising two main activities: a cross-sectional survey conducted prior to COVID-19 vaccine distribution, and semi-structured interviews conducted 4-6 months after vaccine distribution. Data were collected about participant characteristics, vaccination intention prior to distribution, vaccination decision post-distribution, determinants of vaccination intention and decision, activating factors, sources of information and intervention needs. Data from the survey and interviews were analyzed separately and integrated narratively in the discussion.Results
Prior to vaccine distribution, 77% of employees wanted to be vaccinated. Post vaccine distribution, we identified 5 distinct decision-making groups: 1) vaccine believers who actively sought vaccination and included those sometimes described as "immunization advocates", 2) go along to get along (GATGA) individuals who got vaccinated but did not actively seek it, 3) cautious acceptors who got the COVID-19 vaccine after some delay, 4) fence sitters who remained uncertain about getting vaccinated, and 5) vaccine refusers who actively rejected the COVID-19 vaccine. Participants identifying with Black or multiple races were more likely to express hesitancy in their vaccination intention.Conclusion
The findings of our study highlight distinct decision-making profiles associated with COVID-19 vaccination among employees of a VA health care system, and provide tailored recommendations to reduce vaccine hesitancy in this population.Item Open Access Differences in osteoarthritis self-management support intervention outcomes according to race and health literacy.(Health education research, 2013-06) Sperber, Nina R; Bosworth, Hayden B; Coffman, Cynthia J; Lindquist, Jennifer H; Oddone, Eugene Z; Weinberger, Morris; Allen, Kelli DWe explored whether the effects of a telephone-based osteoarthritis (OA) self-management support intervention differed by race and health literacy. Participants included 515 veterans with hip and/or knee OA. Linear mixed models assessed differential effects of the intervention compared with health education (HE) and usual care (UC) on pain (Arthritis Impact Measurement Scales-2 [AIMS2] and Visual Analogue Scale), function (AIMS2 mobility and walking/bending), affect (AIMS2) and arthritis self-efficacy by: (i) race (white/non-white), (ii) health literacy (high/low) and (iii) race by health literacy. AIMS2 mobility improved more among non-whites than whites in the intervention compared with HE and UC (P = 0.02 and 0.008). AIMS2 pain improved more among participants with low than high literacy in the intervention compared with HE (P = 0.05). However, we found a differential effect of the intervention on AIMS2 pain compared with UC according to the combination of race and health literacy (P = 0.05); non-whites with low literacy in the intervention had the greatest improvement in pain. This telephone-based OA intervention may be particularly beneficial for patients with OA who are racial/ethnic minorities and have low health literacy. These results warrant further research designed specifically to assess whether this type of intervention can reduce OA disparities.Item Open Access Identifying Family and Unpaid Caregivers in Electronic Health Records: Descriptive Analysis.(JMIR formative research, 2022-07) Ma, Jessica E; Grubber, Janet; Coffman, Cynthia J; Wang, Virginia; Hastings, S Nicole; Allen, Kelli D; Shepherd-Banigan, Megan; Decosimo, Kasey; Dadolf, Joshua; Sullivan, Caitlin; Sperber, Nina R; Van Houtven, Courtney HBackground
Most efforts to identify caregivers for research use passive approaches such as self-nomination. We describe an approach in which electronic health records (EHRs) can help identify, recruit, and increase diverse representations of family and other unpaid caregivers.Objective
Few health systems have implemented systematic processes for identifying caregivers. This study aimed to develop and evaluate an EHR-driven process for identifying veterans likely to have unpaid caregivers in a caregiver survey study. We additionally examined whether there were EHR-derived veteran characteristics associated with veterans having unpaid caregivers.Methods
We selected EHR home- and community-based referrals suggestive of veterans' need for supportive care from friends or family. We identified veterans with these referrals across the 8 US Department of Veteran Affairs medical centers enrolled in our study. Phone calls to a subset of these veterans confirmed whether they had a caregiver, specifically an unpaid caregiver. We calculated the screening contact rate for unpaid caregivers of veterans using attempted phone screening and for those who completed phone screening. The veteran characteristics from the EHR were compared across referral and screening groups using descriptive statistics, and logistic regression was used to compare the likelihood of having an unpaid caregiver among veterans who completed phone screening.Results
During the study period, our EHR-driven process identified 12,212 veterans with home- and community-based referrals; 2134 (17.47%) veteran households were called for phone screening. Among the 2134 veterans called, 1367 (64.06%) answered the call, and 813 (38.1%) veterans had a caregiver based on self-report of the veteran, their caregiver, or another person in the household. The unpaid caregiver identification rate was 38.1% and 59.5% among those with an attempted phone screening and completed phone screening, respectively. Veterans had increased odds of having an unpaid caregiver if they were married (adjusted odds ratio [OR] 2.69, 95% CI 1.68-4.34), had respite care (adjusted OR 2.17, 95% CI 1.41-3.41), or had adult day health care (adjusted OR 3.69, 95% CI 1.60-10.00). Veterans with a dementia diagnosis (adjusted OR 1.37, 95% CI 1.00-1.89) or veteran-directed care referral (adjusted OR 1.95, 95% CI 0.97-4.20) were also suggestive of an association with having an unpaid caregiver.Conclusions
The EHR-driven process to identify veterans likely to have unpaid caregivers is systematic and resource intensive. Approximately 60% (813/1367) of veterans who were successfully screened had unpaid caregivers. In the absence of discrete fields in the EHR, our EHR-driven process can be used to identify unpaid caregivers; however, incorporating caregiver identification fields into the EHR would support a more efficient and systematic identification of caregivers.Trial registration
ClincalTrials.gov NCT03474380; https://clinicaltrials.gov/ct2/show/NCT03474380.Item Open Access Invisible partners in care: Snapshot of well-being among caregivers receiving comprehensive support from Veterans Affairs.(Health science reports, 2019-03) Miller, Katherine EM; Lindquist, Jennifer H; Olsen, Maren K; Smith, Valerie; Voils, Corrine I; Oddone, Eugene Z; Sperber, Nina R; Shepherd-Banigan, Megan; Wieland, G Darryl; Henius, Jennifer; Kabat, Margaret; Van Houtven, Courtney HaroldBackground and aims
Since May 2011, over 23 000 caregivers of Veterans seriously injured on or after September 11, 2001 have enrolled in the Program of Comprehensive Assistance for Family Caregivers (PCAFC). PCAFC provides caregivers training, a stipend, and access to health care. The aim of this study is to describe the characteristics of caregivers in PCAFC and examine associations between caregiver characteristics and caregiver well-being outcomes.Methods
We sent a web survey invitation to 10 000 PCAFC caregivers enrolled as of September 2015. Using linear and logistic regressions, we examine associations between PCAFC caregiver characteristics and caregiver outcomes: perceived financial strain, depressive symptoms (Center for Epidemiologic Studies Depression Scale [CESD-10]), perceived quality of Veteran's Veterans Health Administration (VHA) care, and self-reported caregiver health.Results
We had complete survey data for 899 respondents. Since becoming a caregiver, approximately 50% of respondents reported reducing or stopping work. Mean time spent providing care was 3.8 years (median 3, IQR 1-5) with an average of 4.9 weekdays (median 5, IQR 5-5) and 1.9 weekend days (median 2, IQR 2-2). The mean CESD-10 score was 8.2 (median 7, 4-12), at the cutoff for screening positive for depressive symptoms. A longer duration of caregiving was associated with having 0.08 increase in rating of financial strain (95% CI, 0.02-0.14). Caregiver rating of the Veteran's health status as "fair" or better was a strong predictor of better caregiver outcomes, ie, self-reported caregiver health. However, higher levels of education were associated with worse caregiver outcomes, ie, lower global satisfaction with VHA care, higher CESD-10 score, and higher rating of financial strain.Conclusions
Higher depressive symptoms among longer duration caregivers, coupled with high rates of reductions in hours worked, suggest interventions are needed to address the long-term emotional and financial needs of these caregivers of post-9/11 Veterans and identify subpopulations at risk for worse outcomes.Item Open Access Mandated caregiver training in the Veterans Health Administration: Caregiver inquiry informs national dissemination.(The Gerontologist, 2022-11) Sperber, Nina R; Boucher, Nathan; Hughes, Jaime M; Bruening, Rebecca; Zullig, Leah L; Decosimo, Kasey; Tucker, Matthew; Christensen, Leah A; Allen, Kelli D; Hastings, Susan N; Van Houtven, Courtney HBackground and objectives
A minority of family caregivers receive training, with implications for their own and their recipient's outcomes. Federal policy has supported implementation and expansion of caregiver training and support. The Department of Veterans Affairs (VA) has developed a national Caregiver Support Program and collaborated with VA health services researchers to explore caregivers' acceptance of an evidence-based training program in preparation for system-wide dissemination.Research design and methods
This approach entailed a convergent mixed-methods design, which involved separate analyses of quantitative and qualitative data. Survey questions based on the Kirkpatrick model for training evaluation measured caregivers' reaction and learning and interview questions elicited caregivers' reports about the value of the program for them.Results
Most caregivers reported satisfaction with the training when responding to survey questions, although qualitative interviews revealed caveats suggesting need to hone the best timing and specific group of caregivers for maximal benefit.Discussion and implications
Our findings indicate that understanding program-user fit may be particularly critical when implementing training for caregivers as they come to the program at different points along their caregiving journey, needing differing types and intensities of support. While a general program may appeal to policymakers aiming to scale caregiver training within a large, heterogeneous system, there may be shortcomings in terms of end-user acceptance and subsequent downstream outcomes such as reach and ultimately program effectiveness. Good, iterative communication flow between program developers and policymakers facilitates this understanding and, in turn, decisions about scaling.Item Open Access Participant evaluation of a telephone-based osteoarthritis self-management program, 2006-2009.(Preventing chronic disease, 2012-01) Sperber, Nina R; Bosworth, Hayden B; Coffman, Cynthia J; Juntilla, Karen A; Lindquist, Jennifer H; Oddone, Eugene Z; Walker, Tessa A; Weinberger, Morris; Allen, Kelli DIntroduction
Self-management support interventions can help improve osteoarthritis outcomes but are underused. Little is known about how participants evaluate the helpfulness of these programs. We describe participants' evaluations of a telephone-based, osteoarthritis self-management support intervention that yielded improved outcomes in a clinical trial.Methods
Participants were 140 people in the intervention arm of the trial who completed an end-of-trial survey. We used mixed methods to describe participants' perceived helpfulness of the program and its components. We compared ratings of helpfulness according to participant characteristics and analyzed themes from open-ended responses with a constant comparison approach. We calculated Pearson correlation coefficients between perceived helpfulness and changes in pain, function, affect, and self-efficacy.Results
The average rating of overall helpfulness on a scale from 1 to 10 was 7.6 (standard deviation, 2.3), and more than 80% of participants agreed that each component (phone calls, educational material, setting goals and action plans) was helpful. Participants had better perceived helpfulness ratings than their counterparts if they were nonwhite, had limited health literacy, had no college education, had perceived inadequate income, were older, had a spouse or were living together in a committed relationship, and had greater symptom duration and less pain. Ratings of helpfulness increased with greater improvement in outcomes. Participants frequently mentioned the health educator's calls as being helpful for staying on task with self-management behaviors.Conclusion
Participants viewed this intervention and each of its components as helpful for improving osteoarthritis symptoms. In addition to the improvements in objective outcomes seen in the clinical trial, these results provide further support for the dissemination of self-management support interventions.Item Open Access Patient perceptions of a comprehensive telemedicine intervention to address persistent poorly controlled diabetes.(Patient preference and adherence, 2017-01) Andrews, Sara M; Sperber, Nina R; Gierisch, Jennifer M; Danus, Susanne; Macy, Stephanie L; Bosworth, Hayden B; Edelman, David; Crowley, Matthew JObjective
We studied a telemedicine intervention for persistent poorly controlled diabetes mellitus (PPDM) that combined telemonitoring, self-management support, and medication management. The intervention was designed for practical delivery using existing Veterans Affairs (VA) telemedicine infrastructure. To refine the intervention and inform the delivery of the intervention in other settings, we examined participants' experiences.Methods
We conducted semistructured interviews with 18 Veterans who completed the intervention. We analyzed interview text using directed content analysis and categorized themes by hemoglobin A1c (HbA1c) improvement (<1% or ≥1%).Results
Participants generally reported greater awareness of their blood glucose levels; however, they described dissatisfaction with the telemonitoring interface and competing demands during the intervention. Participants with <1% HbA1c improvement reported that these challenges interfered with their engagement. Participants with ≥1% HbA1c improvement reported new self-management routines despite challenges.Conclusion
Despite competing demands and frustration with the telemonitoring interface, many participants demonstrated intervention engagement and substantial improvement in HbA1c ($1%). Differences in engagement may reflect differing capacity to manage treatment burden. Because it relies on existing infrastructure, this intervention is a promising model for addressing PPDM within VA. Future work should focus on optimizing systems' telemedicine infrastructure; while reliance on existing infrastructure may facilitate practical delivery, and it may also limit intervention engagement by excessively contributing to treatment burden.Item Open Access Ready, set, go! The role of organizational readiness to predict adoption of a family caregiver training program using the Rogers' diffusion of innovation theory.(Implementation science communications, 2023-06) Van Houtven, Courtney H; Drake, Connor; Malo, Teri L; Decosimo, Kasey; Tucker, Matthew; Sullivan, Caitlin; D'Adolf, Josh; Hughes, Jaime M; Christensen, Leah; Grubber, Janet M; Coffman, Cynthia J; Sperber, Nina R; Wang, Virginia; Allen, Kelli D; Hastings, S Nicole; Shea, Christopher M; Zullig, Leah LBackground
Caregivers FIRST is an evidence-based program addressing gaps in caregivers' skills. In 2020, the Veterans Health Administration Caregiver Support Program (CSP) nationally endorsed Caregivers FIRST, offering credit in leadership performance plans to encourage all VA medical centers (VAMCs) to implement locally. This study examines the association of organizational readiness with VAMC adoption of Caregivers FIRST.Methods
In a cohort observational study, we surveyed CSP managers about their facilities' readiness to implement using the Organizational Readiness for Implementing Change (ORIC) instrument and compared change commitment and change efficacy domains among VAMCs "adopters" defined as delivering Caregivers FIRST within 1 year of the national announcement to those that did not ("non-adopters"). Within "adopters," we categorized time to adoption based on Rogers' diffusion of innovation theory including "innovators," "early adopters," "early majority," "late adopters," and "laggards." Organizational readiness and site characteristics (facility complexity, staffing levels, volume of applications for caregiver assistance services) were compared between "adopters," "non-adopters," and between time to adoption subcategories. Separate logistic regression models were used to assess whether ORIC and site characteristics were associated with early adoption among "adopters."Results
Fifty-one of 63 (81%) VAMCs with CSP manager survey respondents adopted Caregivers FIRST during the first year. ORIC change commitment and efficacy were similar for "adopters" and "non-adopters." However, sites that adopted earlier (innovators and early adopters) had higher ORIC change commitment and efficacy scores than the rest of the "adopters." Logistic regression results indicated that higher ORIC change commitment (odds ratio [OR] = 2.57; 95% confidence interval [CI], 1.11-5.95) and ORIC change efficacy (OR = 2.60; 95% CI, 1.12-6.03) scores were associated with increased odds that a VAMC was an early adopter (categorized as an "innovator," "early adopter", or "early majority"). Site-level characteristics were not associated with Caregivers FIRST early adoption.Conclusions
To our knowledge, this study is the first to prospectively assess organizational readiness and the timing of subsequent program adoption. Early adoption was associated with higher ORIC change commitment and change efficacy and not site-level characteristics. These findings yield insights into the role of organizational readiness to accelerate program adoption.Trial registration
ClinicalTrials.gov, NCT03474380. Registered on March 22, 2018.Item Open Access Understanding the Context for Long-Term Care Planning.(Med Care Res Rev, 2016-06) Broyles, Ila H; Sperber, Nina R; Voils, Corrine I; Konetzka, R Tamara; Coe, Norma B; Van Houtven, Courtney HaroldEvolving family structure and economic conditions may affect individuals' ability and willingness to plan for future long-term care (LTC) needs. We applied life course constructs to analyze focus group data from a study of family decision making about LTC insurance. Participants described how past exposure to caregiving motivated them to engage in LTC planning; in contrast, child rearing discouraged LTC planning. Perceived institutional and economic instability drove individuals to regard financial LTC planning as either a wise precaution or another risk. Perceived economic instability also shaped opinions that adult children are ill-equipped to support parents' LTC. Despite concerns about viability of social insurance programs, some participants described strategies to maximize gains from them. Changing norms around aging and family roles also affected expectations of an active older age, innovative LTC options, and limitations to adult children's involvement. Understanding life course context can inform policy efforts to encourage LTC planning.Item Open Access Women Veterans Experience with the VA MOVE! Weight Management Program.(Women's health reports (New Rochelle, N.Y.), 2020-01) Batch, Bryan C; Brown, Candace S; Goldstein, Karen M; Danus, Susanne; Sperber, Nina R; Bosworth, Hayden BBackground: Obesity prevalence is higher in women veterans overall than their civilian counterparts considering 44% of women veterans are obese. Thus, there is a critical need to understand the facilitators and barriers to women veterans' participation in weight management programs. The objective of this study is to explore facilitators and barriers to weight loss for women veterans enrolled in the Veterans Health Administration Motivating Overweight/Obese Veterans Everywhere (VA MOVE!) weight management program and gather feedback on the design and delivery of the MOVE!Program
Materials and Methods: Primary qualitative data were collected from women veterans who completed at least one MOVE! visit via semistructured telephone interviews. Two authors independently reviewed transcripts for data-derived codes. A content analysis approach was used within the software to code the transcripts. Results: The mean age of participants was 52 years. Sixty-eight percent (N = 17/25) were black, and 52% (N = 13/25) lived >64 kilometers from the location of the MOVE!Program
Facilitators to participation included both intrinsic (e.g., drive to become healthy) and extrinsic (e.g., drive to improve laboratories) motivating factors. Women expressed difficulty with learning in a group setting and applying lessons to their everyday lives. Others reported the setup of group classes triggered their post-traumatic stress disorder and prevented them from fully participating in the program. Additional barriers included distance traveled to group sessions and lack of access to exercise space. Conclusions: Our results illuminate barriers and facilitators to engagement in the MOVE!Program
Many of the barriers highlighted by these women veterans mirror barriers civilian women face, highlighting the possibility that our results could be applied to other programs designed to target weight loss in women.Item Open Access Workforce readiness for pharmacogenomics and key elements for sustainment within the Veterans Health Administration.(Pharmacogenomics, 2024-02) Wu, Rebekah Ryanne; Benevent, Richelle; Sperber, Nina R; Bates, Jill S; Villa, Daniel; Weeraratne, Dilhan; Burrell, Timothy A; Voora, DeepakAim: Understanding barriers and facilitators to pharmacogenomics (PGx) implementation and how to structure a clinical program with the Veterans Health Administration (VA). Materials & methods: Healthcare provider (HCP) survey at 20 VA facilities assessing PGx knowledge/acceptance and qualitative interviews to understand how best to design and sustain a national program. Results: 186 (12% response rate) surveyed believed PGx informs drug efficacy (74.7%) and adverse events (71.0%). Low confidence in knowledge (43.0%) and ability to implement (35.4-43.5%). 23 (60.5% response rate) interviewees supported a nationally program to oversee VA education, consultation and IT resources. Prescribing HCPs should be directing local activities. Conclusion: HCPs recognize PGx value but are not prepared to implement. Healthcare systems should build system-wide programs for implementation education and support. |
Astronomy and space travel have captured my imagination ever since I was a kid. I must have been six or seven when my parents took me into the back yard to show me a comet. I can recall Sputnik (barely), and I eagerly awaited each manned flight that led to the lunar landings.
I've always wanted to see a rocket launch, but during the heyday of the Space Race, Florida was far from when I lived. Twice I was near Cape Canaveral when a shuttle launch was planned; both times the launch was postponed.
The other event that I longed to see was a total solar eclipse. I came close in 1984, witnessing the annular eclipse in Louisiana. 99.2 percent total, but not quite there!
One way or another, I would witness the 2017 eclipse. Its path across the continent guaranteed me an opportunity to see it. If I stayed in Georgia, a four-hour drive would get me there. And if I found work in the Northwest, there's no way I'd allow myself to miss it.
As things turned out, I was the successful bidder on a forestry job on the Warm Springs Indian Reservation, which lay directly in the path of totality. My ticket had been punched. I even found a place to stay that was within the zone.

In the days leading up to the eclipse, I scouted potential viewing sites. Under normal circumstances, this would be fairly easy. But the Nena Springs wildfire started about ten days before Eclipse Day, eventually burning more than 60,000 acres. The road that I wanted to use was closed much of that time.
There was always the option of staying put; the place I was renting would see fifty seconds of totality. By traveling south, I could double that amount, and then some. About 20 miles away, where the flat land drops into a canyon, the Sun would be covered for nearly two minutes. The views were nice, but there were very few places to pull off the road. Most of the way down, there was a guardrail and no shoulder.
After partiality began, I drove down Highway 3. Hardly anyone was on the road. Most of the eclipse watchers had already staked out locations off the road. One car here, five there, ten over yonder. Not exactly a multitude. To the south, a layer of smoke intruded, coming from forest fires in the Cascade Mountains.
As I drove, the smoke got closer to the place the Sun occupied in the sky. The canyon location was no longer the best option. I stopped in Simnasho, known for the Three Warriors convenience store and not much else. Perhaps 100 people were there to view the eclipse. I decided to join them.
By the time I settled in, the light was noticeably dim, and getting dimmer by the minute. Noble Fur kept wanting to wander around, but two large dogs were running loose. Eventually I set her on the hood of the truck, with her leash looped around the radio antenna. I was juggling the cat, two lenses for the DSLR camera, the camera phone, and the welder's glass for looking at the Sun.
On a parking lot surrounded by people and dogs, there was not much of an opportunity to note how wildlife reacted to the sudden change in light. I did notice a half-dozen birds flying low, seemingly looking for a place to roost. A nearby porch light came on.
As totality approached, the DSLR decided that it did not want to take pictures in the dark. Rather than fiddle with it, I set it aside. I've seen plenty of eclipse pictures, and many great images would be captured by those better equipped than I.
It was time to savor the moment. When the last sliver of sunlight disappeared behind the moon, the sky abruptly changed. The darkened sun, surrounded by the corona, was the focal point of everything. There is no use in coming up with superlatives to describe it; they've already been used over and over. Fifteen seconds into totality, I was already wishing for one of those seven-minute eclipses, rather than a paltry minute and forty seconds.
Yes, it was very quiet. But then, the location was not exactly noisy to begin with. The observers cheered and oohed and ahhed for a few seconds; then they admired in silence. Someone pointed out that Venus was in view; there it was to the west, shining bright.
I glanced away for a few moments to look at the surrounding terrain. While it seemed like night overhead, towards the horizons the effect was more like twilight.
Totality ended abruptly. In the minutes prior to it, I was thinking, "Wow, it sure is getting dim." When that first tiny sliver of sun reappeared, my brain said, "Wow, that's bright!"
That's one thing I'll take away from this experience, something I didn't expect. When totality arrives, you know it. When it's over, you know that too.
Within thirty seconds of totality's end, one viewer fired up his car and drove away. He probably leaves baseball games in the fifth inning, too.
There was no reason for me to follow him. I watched the light return to normal strength, looking through the welder's glass as the moon and sun parted company.
On the ride back, two cars passed me in quick succession, one from British Columbia and one from Washington. Hey, eclipse is over, gotta get home now! As for me, I was in no hurry. The eclipse was the only thing on the day's agenda. Nothing else was going to top the spectacular alignment that so few Americans had seen – until now.
What have you noted happening in your area or travels? Those of you who witnessed the eclipse, please add your pictures and observations. I'm sure that some of you have better pictures than mine. |
Identifying mobile network devices
There are different ways you can identify devices.
You can use an external ID (e.g.: "firstname.lastname@example.com"
), IP address with an optional port and phone number.
Identifying devices by external ID
A Device ID is an email-like external identifier for a device (or subscriber) into the network.
It works as a device object created to manage a particular device on the network, for example: email@example.com
Check how it's used in the SDK snippet below.
Identifying devices by IP address and port
Our DeviceIPv4Addr
model allows you to specify Ipv4 and Ipv6 addresses to uniquely identify devices
in order to easily and safely program mobile network features.
Why does the DeviceIpv4Addr model require public or private IP addresses and ports to create a QoD session?
What is NAT technology
As you know, private (local) IP addresses are unique and can be assigned in a private network to securely connect to other resources. That's why, they can be more secure than public (observed) IP addresses since they cannot be seen online as it would happen with public addresses.
Network Address Translation (NAT) helps offering an extra layer of security by hiding the private (local) IP addresses from external networks. It is also a technique that enables sharing a public IP address among multiple resources.
NAT64, on the other hand, acts like translator that enables IPv6-only devices or resources to communicate with IPv4 ones. So, NAT64 helps bridging the gap between the older (IPv4) and newer (IPv6) protocols by enabling communication between resources using them. And if the device is using an IPv6, then you might also be able to avoid specifying the IPv4.
Carrier-grade NAT (CGNAT) is an alternative to NAT and it allows sharing public IP addresses among multiple customers. Network Operators use it to preserve the amount of public IP addresses, since it is already exhausted. The idea is that the IPv4 range is too narrow to be used as a complete IPv4 address for a device. So, Network as Code uses CGNAT and the private IP address or the ports being used defines a sub-range. Effectively enlarging the original 32-bit range of the IPv4 address.
Why do I need to include private, public IP addresses and port?
For the network translation to happen and the QoD session to be established, you will need to specify either of the following:
- Public address and public port.
- Public address and private (local) address (this is the preferred method due to NAT).
So, CGNAT technology is applied here, and you can choose to provide information according to which one is known at the moment.
However, when NAT64 is in use, you will need to identify the device by using its public Ipv4 and port or provide the private Ipv6 address separately.
Identifying devices by phone number
The phone number parameter works as a string and it accepts the "+" sign, but not spaces or "()" marks.
Prefer to use only numbers, such as "36721601234567"
Check the complete snippet below to see all the different ways to identify a device in practice:
Identifying mobile network devices with multiple parameters
Here is an example of how DeviceIPv4Addr
works in our SDK:
import network_as_code as nac
from network_as_code.models.device import DeviceIpv4Addr
client = nac.NetworkAsCodeClient(
my_device = client.devices.get(
ipv4_address = DeviceIpv4Addr(
ipv6_address = "2001:db8:1234:5678:9abc:def0:fedc:ba98",
# The phone number accepts the "+" sign, but not spaces or "()" marks
phone_number = "36721601234567"
TIP: On this page, we further detail which parameters the
method can contain.
How to gather the necessary information to identify devices?
Phone numbers are the most well-known device identifiers, but how can you identify devices in other ways, in case an IoT device does not have a phone number?
That is why the Device ID (also referred to as External Identifier or Network Access Identifier,
e.g.: firstname.lastname@example.com
) can work as an alternate.
In Business to Business (B2B) scenarios, the enterprise owns mobile subscriptions for the devices, and they obtain it from the Network Operator. So, they would know their Device IDs. Enterprises should provide the Device ID related information so that their applications can use them to identify the devices on the mobile network.
In Business to Consumer (B2C) scenarios, phone numbers can act as a simple identifier for devices or users owning the mobile subscription.
IP Addresses are dynamic. So, they are difficult to identify in advance. Whoever owns the IoT device will need to implement a way for it to tell its current IP address(es). Let's suppose you or a client owns a business that manages flying drones. Then, you (or the client) would have an operations center to manage/control these drones. They would need to connect to this operations center whenever they were on and send their connection details with current IP address(es). |
Meaning of the Romanoff family crest symbols
The fleur-de-lis is one of the oldest in international heraldry. It represents purity, light and religious devotion including connotations of the Virgin Mary. It stands as a connection to the family's earliest religious associations and beliefs.
The feathers have been used for centuries to represent family member's characteristics of peace, tranquility, and a sense of calmness. They are a powerful symbol of hope and a reminder of the beauty of life.
Meaning of the Romanoff coat of arms colors
The black color (known as Sable) symbolizes constancy and the enduring nature of the family. It is a symbol of family longevity through time.
The red color (known as Gules) traditionally symbolized martyrdom and the historic military strength of family members when called upon in times of war.
Romanoff name meaning and origin
Romanoff, a surname of Russian origin, is derived from the word "Roman", which means "from Rome". It was traditionally used to denote a person who was Roman or from Rome. This name gained prominence due to the Russian royal family, the House of Romanov, who ruled Russia from 1613 until the Bolshevik revolution in 1917.
History of family crests like the Romanoff coat of arms
Family crests and coats of arms emerged during the Middle Ages, mostly in wider Europe. They were used as a way to identify knights and nobles on the battlefield and in tournaments. The designs were unique to each family and were passed down from generation to generation.
The earliest crests were simple designs, such as a single animal or symbol, but they became more elaborate over time. Coats of arms were also developed, which included a shield with the family crest, as well as other symbols and colors that represented the family's history and achievements.
The use of family crests and coats of arms spread throughout Europe and became a symbol of social status and identity. They were often displayed on clothing, armor, and flags, and were used to mark the family's property and possessions.
Today, family crests and coats of arms are still used as a way to honor and celebrate family heritage.
Romanoff name variations and their meaning
The family name Romanoff has various variations across different regions and cultures. In Russia, it is commonly spelled as Romanov, which is the most well-known variation of the name. This variation is associated with the Russian imperial family, the House of Romanov, which ruled Russia for over three centuries. In other Slavic countries, such as Ukraine and Belarus, the name is often spelled as Romaniv or Romanovych. These variations maintain the Slavic influence and pronunciation of the name. In Western countries, the name is sometimes anglicized as Romanoff, with an additional "f" at the end. This variation is often used to differentiate individuals from the Russian imperial family. Additionally, there may be other minor variations of the name, such as Romanow or Romanowicz, which can be found in different parts of the world. Despite the variations, the name Romanoff remains a distinctive and recognizable surname with a rich history.

## Apostles' Travels to Central and South America: Unveiling the Uncharted Territories
The apostles of Jesus Christ, driven by the Holy Spirit, embarked on arduous journeys to spread the Gospel to the far corners of the earth. While the exact extent of their travels remains shrouded in uncertainty, intriguing evidence suggests that at least one apostle ventured into the uncharted territories of Central and South America. This article aims to explore the historical accounts and scholarly theories surrounding the apostolic mission to this enigmatic region.
**1. Thomas the Apostle: The Pioneer Explorer**
The most compelling evidence points to Thomas the Apostle as the likely candidate for having traveled to the New World. Early Christian writings, such as the Acts of Thomas and the Gospel of Thomas, hint at his missionary journeys beyond the Roman Empire. According to these sources, Thomas ventured eastwards, possibly reaching India, and then continued his journey westward, eventually reaching the Americas.
Historians have identified similarities between Christian traditions found among certain indigenous tribes in Central and South America and the teachings of Thomas. For instance, the Maya of Guatemala have a legend about a white-bearded man who brought them a message of salvation. This man, known as "Zuniga Cacique," bears striking similarities to the description of Thomas in early Christian texts.
**2. The Journey: Unraveling the Enigma**
If Thomas did indeed travel to Central and South America, his journey would have been fraught with challenges and hardships. He would have crossed vast oceans, navigated treacherous jungles, and encountered unknown cultures and languages. The lack of written records from his expedition makes it difficult to reconstruct the exact route he took.
Some scholars speculate that Thomas may have sailed west from the coast of Africa, reaching South America first. He could have then traveled northward along the Andes Mountains, eventually reaching Central America. Alternatively, he may have traveled east from Asia, following the trade routes to the Pacific coast of South America.
**3. The Legacy: Enduring Beliefs and Traditions**
While the full extent of Thomas's influence in the Americas remains unknown, there are tantalizing clues suggesting that he left a lasting legacy. Several indigenous tribes in Central and South America have traditions and beliefs that align with Christian teachings, including the existence of a savior who came from afar.
In Guatemala, for example, the Kekchi Maya have a legend about a white-skinned man named Tecún Umán who led them in a battle against the Spanish conquistadors. Tecún Umán is believed to have been a reincarnation of Thomas the Apostle.
**4. Other Apostles: Exploring Alternative Theories**
In addition to Thomas, some theories propose that other apostles may have also visited the Americas. Bartholomew the Apostle is often associated with India, but some scholars speculate that he could have traveled further west to Central America.
Likewise, Philip the Apostle is said to have traveled to Scythia, which some scholars believe may have included parts of South America. However, these theories lack substantial historical evidence and remain largely speculative.
**5. The Significance: Unveiling the Missionary Spirit**
The possible travels of the apostles to Central and South America highlight the indomitable missionary spirit of the early Church. Driven by a deep conviction in the Gospel, they were willing to venture into uncharted territories and share the message of Christ with all nations.
The apostolic journeys to the Americas, if proven true, would provide a remarkable testament to the universal scope of God's redemptive plan. It would demonstrate that the Gospel had reached the farthest corners of the earth, even before the arrival of European explorers and missionaries.
While the evidence for apostolic travels to Central and South America remains fragmented and open to interpretation, the possibility of such a journey offers a captivating glimpse into the missionary zeal of the early Church. The legacy of Thomas the Apostle, if he indeed visited the New World, continues to inspire and challenge Christians to embrace the Great Commission and spread the Gospel to all nations, even to the most remote and uncharted places. |
Lottery is a form of gambling in which people pay money to win prizes. It is a popular activity in many countries. Some governments run state-run lotteries. Others organize lotteries on a national or regional basis. Many countries have laws regulating lottery activities.
Lotteries have a long history, from ancient China to Roman times to Colonial Virginia. In modern times, they're still used to raise funds for public projects and schools. But critics say states have come to rely too heavily on unpredictable gambling revenues and exploit poor communities. They point out that the poorest third of households buy half of all tickets and that state lotteries advertise most aggressively in those neighborhoods.
A lottery is a game of chance where winners are chosen by a random process, rather than through skill or merit. Prizes may include cash or goods. The word "lottery" comes from the Dutch noun "lot," meaning fate. It has become an important form of taxation and government funding in the United States and around the world.
While the idea of winning a multi-million dollar jackpot is appealing, it's also a huge risk-to-reward investment. Lottery players contribute billions in revenue to the government, which could otherwise be used for other purposes like investing in the future or paying down debt. Some states with income taxes withhold a portion of lottery winnings, but most don't. |
The North of Tyne Citizens' Assembly on Climate Change
The Citizens Assembly saw 50 people from the north east of England come together to help shape the region's response to the climate crisis.
Through the Sortition Foundation, the North of Tyne Combined Authority (NTCA) sent out 10,000 letters in December 2020, inviting randomly selected residents of Newcastle, North Tyneside, and Northumberland to take part. From those who responded 50 people were selected to reflect the diversity of the population in the region.
The Assembly, facilitated by Shared Future on behalf of the NTCA, started on 24 February and ended on 24 March, running for a total of 30 hours over eight sessions. The question raised to the assembly was:
"What should we do in the region to address climate change and its causes fairly, effectively and quickly?"
The NTCA set up the process to help come up with radical actions to slash the area's carbon footprint. Jamie Driscoll, Mayor of North of Tyne, recently said about the Citizens Assembly:
"The climate emergency is real and urgent. But we need to take people with us if we are to tackle it effectively. A Citizens' Assembly is a different way of doing things. It's an opportunity to engage meaningfully with a representative sample of the public and listen to what they have to say." |
Vets / Pharmacies / Animal Behaviorist
(Orlando/Central Florida Area)
There is no substitute for medical care for a sick rabbit and there are no at-home treatments. If your rabbit is sick, it must see a qualified rabbit vet as soon as possible. Responsible pet ownership means taking a sick bunny to a vet. Rabbits become ill and feel pain, just like you and I so please don't look for home remedies when only a vet can diagnose and treat your bunny.
Veterinary medical schools typically do not cover rabbits as a required species, veterinarians interested in rabbit medicine must learn about rabbits elsewhere, such as by attending conferences and completing continuing education modules, and working with rabbit rescue groups. Because rabbit medicine is specialized, you can expect to pay more for an office visit and procedures such as spays and neuters.
Our aim is to include veterinarians who have demonstrated competency with the medicine and surgery of rabbits, and who take the time to educate themselves. The following vets have worked with ORCA members and friends. This is not a complete list of rabbit-savvy vets in Central Florida.
If you are interested in using a veterinarian not on the list, please do your own careful research on the veterinarian. Ask him or her questions to make sure you are comfortable taking your rabbit to that veterinarian. Finally, do not assume that because one veterinarian at an animal hospital is experienced with rabbits, all of the associates are, as well. If you call for an appointment, and are offered an appointment with an associate you do not know, insist on seeing the vet you asked for. When calling, please indicate you received their veterinary listing from ORCA. Remember that choosing a vet is an important, personal decision and you should always meet with or talk to the vet to make sure you are comfortable with his or her experience and procedures prior to your first visit with your bunny.
There are low cost vets that offer services to have your pet fixed. Learn more about Spaying & Neutering your pet and where you can find these locations.

Explore the complete Principles of Adaptive Leadership Series
Introduction: Psychological Leadership
Welcome to a transformative exploration of leadership through the lens of psychology. Drawing inspiration from Daniel Goleman's seminal work, "Emotional Intelligence," we delve into the profound connection between emotional intelligence (EI) and effective leadership. Goleman's insights reveal that EI—comprising self-awareness, self-regulation, motivation, empathy, and social skills—is not just a beneficial trait but a cornerstone of impactful leadership.
The purpose of this article is to uncover the fundamental psychological principles that amplify leadership effectiveness. Whether you're a seasoned manager, an aspiring entrepreneur, or a corporate leader aiming to elevate your team's performance, understanding these principles can significantly enhance your leadership approach. Through this exploration, you will gain actionable insights and strategies to harness your psychological prowess for leadership success, all while maintaining a warm and professional tone that resonates with your experiences and aspirations. Let's embark on this journey to refine your leadership skills, grounded in the science of human behavior and emotion.
Understanding Human Psychology in Leadership
At the core of effective leadership lies a deep understanding of human psychology—specifically, how cognitive and emotional processes shape our interactions and decisions. By grasping these foundational elements, you can enhance your leadership effectiveness, fostering a more engaged and productive team.
Cognitive Processes in Leadership
Cognitive processes involve the mental actions or methods through which knowledge is acquired and problems are solved. These include perception, memory, judgment, and reasoning. As a leader, recognizing how these processes function can help you design strategies that cater to the cognitive strengths of your team. For instance, understanding that people process information differently can guide you to present information in varied formats, ensuring clarity and comprehensiveness.
Emotional Processes in Leadership
Emotional processes pertain to the ability to identify, assess, and control the emotions of oneself, of others, and of groups. Leaders with a strong grasp of emotional dynamics are better equipped to motivate their teams, resolve conflicts, and create a positive work environment. For example, empathy allows you to understand the personal challenges your team members may face and offer support or flexibility that can lead to improved performance and job satisfaction.
Impact on Decision-Making and Interactions
Both cognitive and emotional processes heavily influence leadership decision-making and interpersonal interactions. Leaders who are aware of their own cognitive biases and emotional triggers can make more balanced and fair decisions. Moreover, understanding these psychological underpinnings can enhance your ability to communicate effectively, build stronger relationships, and drive your team toward common goals.
In essence, the integration of cognitive and emotional awareness in leadership not only helps in making informed decisions but also in managing the interpersonal dynamics of a team. By fostering an environment where psychological insights are leveraged to enhance understanding and cooperation, you pave the way for a more adaptive and resilient organization.
The Role of Motivation Theories in Leadership
Understanding motivation theories is pivotal in leadership as it equips you with the tools to inspire and engage your team effectively. Two fundamental theories, Maslow's Hierarchy of Needs and Herzberg's Two-Factor Theory, offer insights into what drives human behavior and how leaders can utilize these drives to enhance team performance.
Maslow's Hierarchy of Needs
Abraham Maslow's Hierarchy of Needs is a motivational theory in psychology comprising a five-tier model of human needs, often depicted as hierarchical levels within a pyramid. From the bottom of the hierarchy upwards, the needs are: physiological, safety, love and belonging, esteem, and self-actualization. For leaders, understanding and addressing these needs can help in motivating team members profoundly and sustainably.
By ensuring that the basic needs of team members are met first (such as fair wages for physiological needs and a safe work environment for safety needs), leaders can then focus on fulfilling higher-level needs like belonging, esteem, and eventually, self-actualization. This approach not only boosts morale but also encourages employees to achieve their full potential, contributing to the organization's goals with greater passion and dedication.
Herzberg's Two-Factor Theory
Frederick Herzberg's Two-Factor Theory, also known as the Motivation-Hygiene Theory, distinguishes between factors that cause job satisfaction (motivators) and factors that prevent dissatisfaction (hygiene factors). Motivators include challenging work, recognition, and personal growth, which affect job satisfaction and productivity directly. Hygiene factors, such as salary, job security, and work conditions, do not motivate if enhanced but can lead to dissatisfaction if insufficient.
As a leader, applying Herzberg's theory involves first ensuring that hygiene factors are adequately addressed to avoid dissatisfaction. Subsequently, introducing motivators like opportunities for professional development, recognizing achievements, and providing meaningful work can lead to higher job satisfaction and motivation.
Enhancing Leadership Practices Through Motivation Theories
By integrating the insights from these motivation theories, you can create a more dynamic and responsive leadership strategy. Recognize that while hygiene factors are essential for preventing dissatisfaction, they do not propel team members to go above and beyond. Motivators, however, can inspire exceptional effort and commitment. Tailoring your leadership approach to fulfill both sets of needs can result in a more motivated, engaged, and productive team, ultimately leading to superior organizational outcomes.
Importance of Emotional Intelligence in Leadership
Emotional intelligence (EI) is a crucial factor that significantly enhances leadership effectiveness. By defining and understanding its components, leaders can cultivate a work environment that fosters productivity, harmony, and resilience.
Defining Emotional Intelligence
Emotional intelligence refers to the ability to recognize, understand, manage, and use one's own emotions positively to relieve stress, communicate effectively, empathize with others, overcome challenges, and defuse conflict. EI is composed of five key components:
Self-awareness - Recognizing one's own emotions and their effect on others.
Self-regulation - Managing or redirecting one's disruptive emotions and impulses and adapting to changing circumstances.
Motivation - Harnessing emotions to pursue goals with energy and persistence.
Empathy - Understanding, recognizing, and considering other people's emotions, an essential part of developing social skills.
Social skills - Managing relationships to move people in desired directions, whether in leading change initiatives, persuading others, or resolving conflicts.
Impact of Emotional Intelligence on Leadership
The ability to manage both your own emotions and those of others provides a powerful tool for leadership. Here's how each component of EI contributes to leadership effectiveness:
Self-awareness enables leaders to understand their own emotional triggers and how they affect their decisions, thus improving their judgment and helping to maintain their integrity.
Self-regulation fosters a calm and reliable leadership style. By staying in control, leaders can create a feeling of trust and fairness in the workplace.
Motivation in leaders is contagious; their passion and commitment can inspire others, driving the team forward.
Empathy is critical for managing a successful team or organization. It allows leaders to understand and support their colleagues, fostering a positive work environment and enhancing employee performance.
Social skills enable leaders to quickly find common ground with others, build rapport, and maintain wide networks of contacts that can help in achieving personal and organizational goals.
Effective leaders with high emotional intelligence can manage stress better, lead and motivate others more effectively, and face workplace challenges more efficiently. They are able to understand and navigate their social work environments, creating a collaborative, productive, and rewarding culture.
Psychological Impact of Leadership Styles
Leadership styles significantly influence team dynamics and individual performance. Understanding the nuances of different leadership approaches—such as authoritarian, democratic, and laissez-faire—can help leaders tailor their strategies to optimize team effectiveness and morale.
Overview of Leadership Styles
Authoritarian Leadership:
This style is characterized by individual control over all decisions with little input from group members. Leaders dictate policies and procedures, decide what goals are to be achieved, and direct all activities without any participation from subordinates.
Democratic Leadership:
Also known as participative leadership, this style involves team members in the decision-making process. The leader retains the final decision-making authority but gathers information, feedback, and insights from employees before making a decision.
Laissez-Faire Leadership:
A hands-off leadership style where leaders provide little or no direction and give employees as much freedom as possible. All authority or power is given to the employees and they must set their own goals, make decisions, and resolve problems on their own.
Psychological Effects on Team Dynamics and Individual Performance
Authoritarian Leadership:
Psychological Impact: This style can lead to a reduction in individual team members' sense of autonomy and creativity, potentially increasing efficiency for routine and unskilled tasks but decreasing it for tasks requiring innovation and creativity. It may be effective in situations where decisions need to be made quickly, but it can also lead to high levels of dissatisfaction and turnover.
Democratic Leadership:
Psychological Impact: Encourages higher job satisfaction and greater team spirit as it promotes engagement and allows team members to feel valued by contributing to decision-making processes. This can lead to higher motivation and better problem-solving due to varied inputs, but potentially slower decision-making processes.
Laissez-Faire Leadership:
Psychological Impact: Can be highly effective with skilled, motivated, and self-directed team members, leading to high innovation and creativity. However, it can also result in a lack of direction and uncertainty among team members who need more guidance and structure, potentially leading to poor performance and low motivation if not managed correctly.
Optimizing Leadership Approach
Understanding these styles and their psychological impacts allows leaders to adopt the most appropriate approach depending on the situation, the task at hand, and the team's needs. Effective leaders often blend elements of these styles to match the dynamic conditions and diversity within their teams. By doing so, they can foster a work environment that not only drives organizational success but also supports the well-being and development of every team member.
By being mindful of the psychological effects of their leadership style, leaders can significantly influence both team cohesion and individual performance, leading to a more effective, motivated, and satisfied workforce.

Why I'm Learning Irish in Luxembourg
People here often wonder why I'm learning Irish in Luxembourg. "You know that if you speak English, you don't need to learn Irish to go to Ireland," they say. Well, maybe learning a language is not about necessity and utility.
Growing up in Luxembourg, a country with less than a million inhabitants, I have a deeper understanding of the importance of a language for a country's history and culture. Only 52% of the residents of Luxembourg are Luxembourgers and not all of them speak Luxembourgish. I have witnessed so many people moving to Luxembourg for employment reasons and not even trying to learn basic words like 'Hello' and 'Goodbye' in Luxembourgish. Since they speak French, German or English, they don't need it to get by.
Fair enough. But to me, this means that they are only taking advantage of all the benefits Luxembourg has to offer without trying to understand its interesting culture and complicated history. I have always admired and supported the few people who made the effort to at least learn some basic Luxembourgish. This is one of the reasons that motivated me to learn Irish from my home here in Luxembourg.
When I heard about the Irish-speaking communities of Ireland slowly having to relocate because of the rising living costs (caused by people moving to Ireland to work for big companies), it reminded me of the situation in my own country. It seems that people value financial wealth more than they value centuries of history and culture. To me, learning a country's language is a sign of respect and appreciation for what it has to offer.
I grew up speaking Luxembourgish, then I learned German and French. In high school, I learned English and taught myself some Dutch. Then, in university, I had to learn Latin. I've always felt comfortable in a multilingual community. Three years ago, I decided to learn Italian. I met some people who were also interested in learning Italian. Reading books in another language turned out to be a conversation starter and a great way to meet new people. I made friends for life and even traveled to Italy with a German friend with whom I enjoyed learning Italian. We even took a two-week language class in Rome together. Those are memories I will cherish forever.
After a few years of intensive studying, traveling all across Italy and living in Rome for six months, I decided that Italian was no longer challenging enough and I was ready to learn a new language. Spanish would have made sense and I probably could have learned it very quickly, but like I said, I wanted something more challenging. Then I traveled to Ireland. When I first landed at the airport in Dublin and saw all the signs written in Irish and couldn't decipher a word, I was intrigued.
During this trip, locals talked about the importance of the Irish language and my fascination grew. I decided to completely immerse myself in the language and learn more about the rich history of the country. When I finally decided to apply for a three-year program at TU Dublin, it made even more sense for me to keep learning Irish. I saw this as an opportunity to prepare for my big move and a way to be included once I lived there.
There is another reason why I decided to learn Irish. It is more of a personal reason. My family has a history of Alzheimer's disease. I have witnessed my grandmother's and her sisters' mental health declining as the years went by. Now, my mother is displaying the same symptoms. This is a very scary situation to be in: to be unable to prevent it and know that I will probably be affected by it too. However, I have read that the best thing one can do to stimulate one's brain is to learn a new language. Now, one could argue that I could have learned any language and that may be true, but I think that Irish, as a Celtic language, is so fundamentally different from any other language I have learned so far. I have to completely rethink all the existing grammar structures in my head and use a different approach than the one I am used to. I believe that Irish is giving my brain all the stimulation that it needs.
In conclusion, I feel like learning Irish brings me closer to the people in Ireland and gives me a greater understanding of their fascinating background. Irish challenges me, not only mentally, but also to grow as a person and to be open to a different culture. I'm happy to keep learning Irish in Luxembourg – ar aghaidh linn!

Commission Artist Painting is an exciting process that allows artists to bring their vision to life and collectors to acquire unique artwork tailored to their preferences. However, the commissioning process can be complex and involves various considerations and steps. In this comprehensive guide, we will explore every aspect of commissioning paintings, from understanding the process to finding the perfect artist, collaborating effectively, and navigating the legal and financial aspects. Whether you are an artist looking to accept commissions or a collector interested in commissioning a painting, this guide will provide you with the knowledge and insights to master the art of commissioning.
1. Understanding the Commissioning Process
Creating a Vision
The first step in commissioning a painting is to create a clear vision of what you want to achieve. Consider the subject matter, style, size, medium, and any specific details or themes you want the artwork to incorporate. Take some time to reflect on your preferences and desired outcome. This will help you communicate effectively with the artist and ensure that their interpretation aligns with your expectations.
Setting Expectations with Artists
Once you have a vision in mind, it is important to discuss and set expectations with the artist you are considering for the commission. Clearly communicate your requirements, including any deadlines, budget constraints, and desired level of involvement in the creative process. This will allow the artist to assess if they are the right fit for your project and ensure that both parties are on the same page from the start.
Negotiating Terms and Contracts
Before moving forward with the commission, it is crucial to negotiate and finalize the terms of the project. This includes discussing the pricing structure, payment schedule, and any additional expenses such as shipping or framing. It is advisable to have a written contract in place to protect both the artist and the collector. The contract should clearly outline the scope of work, timeline, payment terms, and any copyright or reproduction rights. Consulting a legal professional specializing in art contracts is recommended to ensure all aspects are covered.
2. Finding the Perfect Artist for Your Commission
Exploring Different Artistic Styles
When looking for an artist to commission, it is essential to explore different artistic styles that resonate with your preferences. Research various art movements, such as realism, impressionism, abstract, or modern, to determine which style aligns with your vision and personal taste. Consider visiting art galleries, attending exhibitions, or browsing online platforms dedicated to showcasing artists' portfolios.
Researching and Reviewing Artist Portfolios
Once you have identified artists whose styles appeal to you, take the time to thoroughly research and review their portfolios. Examine their past commissions and completed artworks to assess the quality, consistency, and versatility of their work. Pay attention to the use of color, composition, technique, and attention to detail. Additionally, read artist biographies and statements to gain insights into their inspirations, artistic process, and professional background.
Networking and Recommendations
Networking within the art community and seeking recommendations from trusted sources can be a valuable way to find the perfect artist for your commission. Attend art events, join artist associations, and engage with online art communities to connect with artists and fellow collectors. Seek recommendations from other collectors, art consultants, or gallery owners who are knowledgeable about different artists and their specialties. Personal referrals often lead to discovering hidden talents and establishing fruitful collaborations.
3. Collaborating with Artists to Bring Your Vision to Life
Communicating Your Ideas Effectively
Effective communication is crucial for a successful collaboration. Clearly articulate your ideas, inspirations, and preferences to the artist, providing visual references or sketches if necessary. Be open to the artist's suggestions and interpretations while ensuring that your vision remains at the core of the artwork. Regularly communicate with the artist throughout the process, seeking updates and addressing any questions or concerns that may arise.
Providing Feedback and Revisions
As the artist progresses with the commission, they will likely provide updates and seek feedback. It is important to provide constructive feedback in a respectful manner, highlighting what you appreciate and any areas that may need adjustment. Remember that the creative process often involves experimentation and evolution, so be open to revisions and trust the artist's expertise. Effective collaboration and mutual respect will result in a final piece that meets or exceeds your expectations.
Budgeting and Timing Considerations
Commissioning a painting involves financial and timing considerations. Discuss the budget with the artist upfront to ensure that it aligns with their pricing structure and your expectations. Keep in mind that factors such as the size, complexity, and medium of the artwork may influence the cost. Additionally, consider the artist's workload and availability, as they may have other ongoing projects or exhibitions. Agree upon a realistic timeline for the completion of the commission to avoid any misunderstandings or disappointments.
4. Navigating the Legal and Financial Aspects of Commissioning
Understanding Intellectual Property Rights
Intellectual property rights are an important aspect of commissioning a painting. Both the artist and the collector should have a clear understanding of who will hold the copyright and reproduction rights. This should be addressed and agreed upon in the contract. Copyright typically remains with the artist unless negotiated otherwise, while reproduction rights may be granted to the collector for personal or commercial use. It is advisable to consult a legal professional to ensure that all rights and permissions are appropriately documented.
Establishing Payment Terms and Installments
Payment terms and installments should be established and mutually agreed upon between the artist and the collector before starting the commission. Discuss the payment schedule, including any initial deposit, subsequent installments, or a final payment upon completion. To protect both parties, consider using a secure payment method and ensure that the contract reflects the agreed-upon payment terms. Transparency and clarity regarding financial matters contribute to a smooth and professional working relationship.
Ensuring Insurance and Shipping Logistics
Insurance and shipping logistics are critical aspects when commissioning a painting. Discuss with the artist if they provide insurance coverage during the creation and transportation of the artwork. If not, consider obtaining fine art insurance yourself to protect the artwork from any potential damage or loss. Additionally, agree upon the shipping method, packaging requirements, and who will bear the associated costs. Properly documenting the condition of the artwork upon receipt is also advisable.
Commissioning a painting is an enriching journey that allows artists and collectors to collaborate in the creation of a unique and meaningful artwork. By understanding the commissioning process, finding the perfect artist, collaborating effectively, and navigating the legal and financial aspects, you will be well-equipped to master the art of commissioning. Remember to approach each step with careful planning, open communication, and a shared passion for art, resulting in a rewarding and fulfilling experience.

One of the key factors determining the economic development of a country is the health of its population. Good public health is considered fundamental to the welfare of a society. Health, according to the World Health Organization (WHO), is a state of complete physical, mental and social well-being and not just merely the absence of disease. Today we are in the midst of a health crisis in the form of the novel corona virus pandemic that have affected people in hundreds of thousands across the globe. Never in our wildest dreams did we think that we would ever come across a situation like this. Terms like social/physical distancing, self-isolation, lockdown and even pandemic were not in our vernacular before. We are facing one of the greatest challenges, with normalcy yet to be restored as governments try to contain the infection spread. In our State, the number of people who are testing COVID-19 positive is rising daily and more cases are likely to emerge in the coming weeks. In such a public health emergency, our frontline warriors are just there in the battlefield fighting the pandemic tooth and nail to protect the community. The pandemic has posed intense hardships to our society but the strength, resilience and concern of our healthcare professionals are far greater who are working vigorously round the clock to keep our community safe and healthy. They are the ones who are actually putting their own lives at risk while treating a corona positive/suspected patient and hence run a high risk of getting infected. They are working untiringly, helping people relentlessly combat the contagion and are trying their utmost to prevent patients spreading virus to others. Reportedly, levels of contagion spread even among the healthcare workers have also started ringing alarm bells. So far, at least 239 frontline workers have tested positive and they account for 7% of the total cases in the State. There are also reports that some of their relatives have been infected. There is no denying the fact that the novel corona virus has pushed us all to a state of immense crisis. Apart from the doctors and other healthcare workers, our nursing workforce is putting itself in harm's way to save our lives. Undoubtedly, nurses are the first line of defense in any healthcare issue. Today, as the world is putting up a united front to fight this crisis, our nurses and midwives are also the frontline soldiers in this battle who selflessly put their health and strength on the line for the well-being of others on daily basis. They are the unsung heroes who have exceptional levels of workload, particularly those specialized in intensive care units, in healthcare management or those directly involved in combating the lethal virus. They, along with other healthcare staff, are fighting the killer virus by providing high quality treatment and care. They are organizing and reorganizing wards to open more beds for infected patients while keeping others, including women in labour, safe and healthy. They are taking stock of equipment and lending it across units. With patients testing positive on the rise, nurses are on toes 24/7. They are providing advanced levels of care for emergencies and trauma. They are not only risking their lives but also keeping their duty above everything else. They are devoting hours, days and weeks to taking care of patients. In a scenario like this, we need to support them and take a moment to thank them for their commendable services. Nobody could have imagined the critical importance of nurses in our society brought into focus so clearly by the outbreak of COVID-19. The invaluable role they are playing is a testimony of their sacrifice, courage and commitment to a healthier and safer society. They have been exhibiting strength and care for patients, check on them, comfort and clean them up even if patients are unkind and ungrateful to them. Despite all these odds, nurses alongside other healthcare professionals are serving the society selflessly to their best expertise. This being so, our society needs to support and take care of nurses and other healthcare providers. Our society depends on their conviction to treat the public every day with their clinical excellence and deliver care with compassion. As the whole healthcare experts are on the forefront of getting us through this catastrophic situation, we need to strengthen their resilience with our gratitude and honour their contribution. |
Color vision is an important sensory capability that enhances the detection of contrast in retinal images. Monochromatic animals exclusively detect temporal and spatial changes in luminance, whereas two or more types of photoreceptors and neuronal circuitries for the comparison of their responses enable animals to differentiate spectral information independent of intensity. Much of what we know about the cellular and physiological mechanisms underlying color vision comes from research on vertebrates including primates. In insects, many important discoveries have been made, but direct insights into the physiology and circuit implementation of color vision are still limited. Recent advances in Drosophila systems neuroscience suggest that a complete insect color vision circuitry, from photoreceptors to behavior, including all elements and computations, can be revealed in future. Here, we review fundamental concepts in color vision alongside our current understanding of the neuronal basis of color vision in Drosophila, including side views to selected other insects.

In the life of insects and many vertebrates including humans, color vision is abundant and plays a central role in guiding behavior. It allows the discrimination of spectrally distinct stimuli regardless of their relative intensity. In humans, the perception of color is described by the attributes color hue, saturation, and brightness (Kelber and Osorio 2010; Lunau 2014), and it can be associated with additional sensations, emotions, or call up memories, explaining the importance of color for arts (Backhaus et al. 1998). How insects including Drosophila perceive color we cannot know. However, we can analyze and quantify the spectral discrimination abilities of insects in behavioral experiments, and we can refer to their color vision and presented color stimuli using the parameters spectral information, spectral purity, and intensity. Analyzing the underlying neuronal circuitries in insects and other taxa can provide us with a better understanding of the question whether the miniature brains of insects employ similar or different physiological, computational, and network mechanisms to derive information on spectral content as the much larger brains of, for instance, vertebrates (Dacey and Packer 2003; Gegenfurtner and Kiper 2003; Kelber et al. 2003; Gegenfurtner 2003; Solomon and Lennie 2007; Osorio and Vorobyev 2008; Jacobs 2008).
The observation that 'simple organisms' like insects are capable of color vision has been shown for the first time in the pioneering work of Karl von Frisch (von Frisch 1914). He conditioned honey bees to colored cardboards and showed that trained bees can distinguish the conditioned color from 30 different shades of gray. At this time, color vision was widely considered a privilege of certain vertebrates including humans, despite the many pollinating and frugivorous insects that obviously use spectral content to guide behavior. Today, we know that a wide range of animals from different taxa, among them numerous arthropods, are capable of color vision. Color vision endows these animals with extra power for the generation of contrast that facilitates image segmentation. The blossom of field cow-wheat that is frequently visited by different insects is difficult to recognize in the black and white image in Fig. 1a. However, addition of spectral information to the image makes the flower pop out from the green meadow (Fig. 1a) (colors are named according to human perception throughout the manuscript). Thus, color vision facilitates the identification of objects and enables a better judgement of their quality. The latter is demonstrated, for instance, by the coloration of fruits and flowers that often signal ripeness or that it is worth visiting a plant for its nectar (Fig. 1b). This includes changes in floral color that are exhibited by many angiosperm plants and that have been shown to instruct the behavior of pollinators (Weiss 1991).
Next to this important function in the identification of sources of food, color vision can have an important role in the identification of predators, conspecifics and in communication (Poulton 1890; Osorio and Vorobyev 2008; Lunau 2014; Osorio and Cuthill 2015; Cuthill et al. 2017). For instance, Heliconius butterflies display a warning wing pattern that is shared among different local butterfly species. Yellow color patches with additional reflection in the UV range and additional rhodopsin molecules that provide extra sensitivity in the UV range in Heliconius numata have been interpreted in the context of intraspecific communication (Kronforst et al. 2006; Bybee et al. 2012) (Fig. 1c). Also, Diptera and Hymenoptera display colorful wing patterns (Fig. 1d; Shevtsova et al. 2011). Two recent studies, one on Drosophila melanogaster and one on Drosophila simulans demonstrate that these wing interference patterns serve intraspecific communication and sexual selection behavior (Katayama et al. 2014; Hawkes et al. 2019).
The wavelengths contributing to color vision and behavior strongly depend on the types of photoreceptors and their spectral sensitivities. The buttercup flower is uniform yellow for a human observer (Fig. 1e, left). Its UV reflectance (Fig. 1e, right) is not detected by the short (S), middle (M) and long (L) wavelength-sensitive cones that govern color vision in humans, and that have likely evolved to solve other tasks, including the detection of reddish fruits against green foliage (Mollon 1999; Regan et al. 2001; Melin et al. 2013). In contrast, the contained reflection in the UV range is very well visible to many insect pollinators that have photoreceptors with spectral sensitivity in the UV range (Menzel and Backhaus 1991; Briscoe and Chittka 2001; Chen et al. 2013; Lunau 2014). This example highlights that the detection of color depends on who is looking. The spectral properties of photoreceptors and the exact neuronal mechanisms for the comparison of their signals determine the range and type of spectral contrast that can be detected. Thereby, subtle differences in the properties of the color vision system can decide whether or not small differences in the spectral advertising strategies of flourishing plants can be detected, as recently shown for a mixed community of local bee pollinators and their preferred plants (Shrestha et al. 2019).
In local communities of pollinating insects and plants, the wavelengths where sharp changes in the reflectance of flowers occur can correspond well with the wavelengths where pollinators have maximum wavelength discrimination ability, as shown for instance, for different plant–bee communities (Chittka and Menzel 1992; Dyer et al. 2012). In this sender–receiver interplay, it is difficult to judge whether also the visual capabilities of the pollinators influence the floral color display. Using spectral analysis of flower signals and models of insect color vision, this has recently been suggested for a plant–pollinator community with reduced diversity of floral visitors. On a southern ocean island, with flies as the only pollinators, the chromatic capabilities of the fly visual system seemingly impose a filter on floral color display and plant community assembly (Shrestha et al. 2016).
In summary, colored traits and color detection are of great importance in the life of many insects (Hempel de Ibarra et al. 2014; Cuthill et al. 2017; Lebhardt and Desplan 2017). In contrast to bees or butterflies, however, we know relatively little about the ecological functions of color vision in Drosophila. Further studies, particularly in its natural habitat that could be related to the behavioral studies under laboratory conditions, would be very valuable (Dickinson 2014).
Photoreceptor opponency—a hallmark of color vision
Color vision is the result of sequential processing stages. In the first stage of color processing, photoreceptors report spectral and intensity changes of light as a change in membrane potential. Hereby, the spectral sensitivity of a given photoreceptor determines its probability to absorb a photon with a certain wavelength. The photoconversion of light energy during phototransduction (revealed in Drosophila in great detail and reviewed in Hardie 2001; Hardie and Juusola 2015) is independent of the wavelength of the absorbed photon(s). The information on the wavelength of a photon is lost in the moment it is absorbed by the photoreceptor. An increase in the photoreceptor response can similarly arise from an increase in light intensity or from the wavelength of the stimulus getting closer to the wavelength of maximal sensitivity of the photoreceptor (Fig. 2a). Consequently, a visual system with a single type of photoreceptor cannot discriminate the spectral property of a stimulus from its intensity. Numerous physically different stimuli can elicit same responses (Fig. 2a and a'). These circumstances are the key predictions of the 'principle of univariance' (Rushton 1972).
In the second stage of color processing, the responses of different types of photoreceptors with different spectral sensitivities are compared by the nervous system. In this process, two, three or more different types of photoreceptors do per se not overcome the limitations imposed by the principle of univariance. Multiple receptor classes are not sufficient but necessary for color vision. It is the comparison of their activities that provides information about the spectral properties of a visual stimulus (Kelber and Osorio 2010; Mollon 1999). Thus, in its 'simplest' form, color vision is dichromatic and employs two types of spectrally distinct photoreceptors (Fig. 2b, b′). Summation of their output yields a measure of absolute intensity, and calculation of the difference between the responses of both types of photoreceptors enables the encoding of spectral information. The resulting color opponent responses have been observed in second- or higher-order postsynaptic neurons that are excited at one wavelength and inhibited at another (Fig. 2c). However, fingerprints of color opponent processing can already be detected in certain photoreceptors and in particular in the presynaptic terminals of photoreceptors (see 'circuit mechanisms'). In the spectral range where the calculated difference between the photoreceptor sensitivities has its maximum slope, the power of animals to discriminate wavelength differences is often the highest. Still, two different photoreceptor types can be stimulated to the exact same extent by a wide range of metameric stimuli with very different wavelength composition (Fig. 2b, b'). Such metameric stimuli cannot be discriminated by the observer. This ambiguity can be reduced by employing more types of photoreceptors. The number of naturally occurring spectral signals that can elicit identical responses in different photoreceptor types decreased with increasing number of photoreceptors types (Osorio and Vorobyev 2008). The importance of color opponent processing for color vision can hardly be overrated (Chittka et al. 1992; Dacey and Packer 2003; Gegenfurtner and Kiper 2003; Jacobs 2014; Demb and Singer 2015). In fact, the concept of color opponency dominates the way how researchers think about color vision since Hering published his opponent color theory more than 100 years ago. Ever since, the search for individually identifiable neurons that exhibit color opponent processing became an important aspect of color vision research (Hering 1878; Backhaus et al. 1998; Jacobs 2014).
In insects, the diversity of photoreceptors can vary considerably from one species to another. For instance, the visual systems of cockroaches and many ant species have two types of spectrally different photoreceptors (Mote and Goldsmith 1970; Yilmaz et al. 2017). Vision in honey bees involves photoreceptors that are most sensitive in either the UV, blue, or green range of the spectrum (Fig. 2d). In Drosophila and a number of other flies, the visual system harbors five photoreceptor types (Fig. 2e). An even larger diversity is found in the butterfly Papilio xuthus with a retina containing six 'classes' of photoreceptors (Fig. 2f) or the bluebottle butterfly Graphium sarpedon that even has 15 types of photoreceptors (Chen et al. 2016).
Does color vision in these animals necessarily involve all photoreceptor types? And does a higher grade of spectral photoreceptor diversity in an animal correlate with better color vision? Experiments comparing trichromatic RGB devices and hyperspectral cameras demonstrate that multiple, narrow-band sensors enable better reconstructions of a given spectrum (Garcia et al. 2015). In biological systems, however, narrow bandwidth photoreceptors come at a cost of a low signal-to-noise ratio (van Hateren 1993; Osorio and Vorobyev 2008). Also, increased diversity of both photoreceptors and neural circuits that mediate their comparison increases the metabolic and other costs of every bit of encoded spectral information (Niven and Laughlin 2008). Thus, the question arises how many types of different photoreceptors with what kind of spectral tuning properties (shape and width) are optimal for color vision. Studies that used spectra of natural scenes with assumed ecological relevance and models of color vision in different animals suggest that the encoding of spectral information is not improved by more than five types of photoreceptors (reviewed in Osorio and Vorobyev 2005). Thus, the function of higher photoreceptor diversity in color vision remains an open question. In some animals, specific photoreceptor types might drive wavelength-specific behavior (Kelber et al. 2003; Kelber and Osorio 2010).
Detailed insights into the diversity of insect retinae and the contribution of photoreceptors to behaviors guided by spectral cues have been revealed (Kelber et al. 2003; Kelber and Osorio 2010; Hempel de Ibarra et al. 2014; Arikawa 2017). However, our understanding of the molecular mechanisms, physiology, and circuit implementation of color vision in insects is still limited. Help might come from Drosophila where advances in genetic targeting of single cell types, anatomical, physiological, perturbational, and behavioral investigation open new avenues to address these questions.
The Drosophila retina and optic lobe
Drosophila, as most other insects, possesses two compound eyes, each equipped with 750–800 ommatidia. In other insect species, the number of ommatidia per eye can be as low as a dozen and up to several thousand (Lunau 2014). Each individual ommatidium of Drosophila houses eight photoreceptors, which is common to Diptera and most other insects. Specific combinations of photoreceptor types give rise to different types of ommatidia. Drosophila ommatidia house six outer photoreceptors R1–R6 (short visual fibers, svfs) that project to the first optic neuropil, the lamina, and a pair of superimposed inner R7 and R8 photoreceptors (long visual fibers, lvfs) that project to the second optic neuropil, the medulla (Fig. 3a). Gene regulatory networks and a mix of local signaling events and stochastic mechanisms specify photoreceptor cell fate and give rise to the three ommatidial types of the main part of the Drosophila eye (reviewed in Johnston 2013; Mikeladze-Dvali et al. 2005). The large majority of ommatidia belong to the yellow (y) and pale (p) subtype that are randomly distributed at a ratio of roughly 2:1 over the retina (Franceschini et al. 1981; Chou et al. 1996). In Drosophila, ommatidia usually follow the 'one photoreceptor–one rhodopsin' rule and rhodopsin expression in R7/R8 is tightly coupled: R7p and R8p express rh3 and rh5 with maximum sensitivities in the short-UV and blue spectral range, respectively. R7y and R8y express rh4 and rh6 with maximum sensitivity in the long-UV and green spectral range, respectively (Salcedo et al. 1999; Figs. 2e,3a). Yellow ommatidia in the dorsally oriented third of the retina (dorsal-yellow, dy) break with the 'one photoreceptor—one rhodopsin' rule (Mazzoni et al. 2008). In dy ommatidia, R8 express rh6 as in y ommatidia, but R7 co-express rh4 and rh3 (Fig. 3a). In addition to the three types of ommatidia in Drosophila, there are ommatidia specialized in the detection of polarized light in the dorsal-most retina, the so-called dorsal rim area (DRA), that are also present in many other insects (reviewed in Mathejczyk and Wernet 2017). Also in honey bees and Papilio xuthus, different combinations of photoreceptors establish three types of ommatidia (Fig. 3b, c). Notably, it has been shown recently that two butterfly species employ gene regulatory mechanisms that resemble mechanisms in Drosophila to specify the random ommatidia mosaik (Wernet et al. 2006; Perry et al. 2016).
In contrast to bees and butterflies that have a so-called fused rhabdom in which the light-sensitive rhabdomeres are in close proximity and act as a single light guide with a shared optical axis, the rhabdomeres of Drosophila's R1–R6 stay optically isolated from each other (Fig. 3). Only the rhabdomeres of the central photoreceptors R7 and R8 form an optical unit. In this 'light guide', R7 filters the light before the remaining light reaches R8 (Trujillo-Cenóz and Melamed 1966; Braitenberg 1967). Furthermore, in Diptera and few other insects (Lunau 2014), one outer photoreceptor of each of six neighboring ommatidia and one pair of R7/R8 from a seventh ommatidium receive light from the same location in visual space. Their axons converge in 1 of about 750 cartridges of the lamina, visual sampling units that reflect both the ommatidial organization of the compound eye and the wiring of 'neuronal superposition' eyes (Kirschfeld 1973; Langen et al. 2015). Other than in butterflies and bees, where synaptic interactions in the lamina are likely involved in color opponent processing or in increasing wavelength specificity (Takemura et al. 2005; Chen et al. 2013), lvfs in Drosophila pass the lamina without making synapses (Fig. 4, Chen et al. 2019; Meinertzhagen and O'Neil 1991; Menzel and Backhaus 1991; Menzel and Blakers 1976; Ribi 1981; Takemura and Arikawa 2006). The terminals of R7 and R8 in Drosophila are often described to 'precisely' terminate in medulla layer m6 and m3, respectively (Fig. 4a; Takemura et al. 2008), but reconstructions based on serial electron microscopic data show that R7 forms chemical synapses in m6 and all distal layers, and R8 in m1–m3 (Takemura et al. 2013).
In each lamina cartridge, the signals from R1–R6 are conveyed to the large lamina monopolar cells L1–L3 and to a lamina intrinsic amacrine cell (Meinertzhagen and O'Neil 1991). Eleven different cell types of each cartridge connect the lamina with the medulla, the lamina monopolar cells L1–L5 that send their axons to the medulla, the centrifugal cells C2 and C3 that send their axons to the lamina, T1, Lawf1, and Lawf2 cells (reviewed in Borst et al. 2010; Tuthill et al. 2013). The medulla is the first optic neuropil that receives signals from photoreceptors with different spectral sensitivities and it harbors color vision circuitries (see 'circuit mechanisms'). In addition to the retinotopic projections of the lamina neurons and the terminals of the lvfs R7 and R8, each medulla column (visual sampling unit of the medulla) houses more than 60 different cell types (Fischbach and Dittrich 1989; Takemura et al. 2013, 2015). Among these are local interneurons including multi-columnar distal medulla (Dm) cell types that laterally connect medulla columns, and transmedulla (Tm) neurons that connect the medulla to the lobula or the central brain. Different cell types directly postsynaptic to R7 and R8 have been identified by genetic labeling techniques and serial electron microscopic reconstructions (Fig. 4a) (Gao et al. 2008; Takemura et al. 2013; Karuppudurai et al. 2014; Takemura et al. 2015). Insights into the contribution of some of these cell types to neuronal circuitries underlying behavior guided by spectral cues are described in detail in our section on circuit mechanism (below). The importance of the medulla and lobula for color vision in insects is generally supported by the observation of color opponent neurons in theses neuropils in different bees and butterflies (Swihart 1972; Kien and Menzel 1977a, b; Hertel 1980; Yang et al. 2004; Paulk et al. 2008, 2009a). The circuitries of the lobula plate have so far not been linked to spectral processing. They play an important role in the computation of visual motion and navigation (see review by Borst et al. 2019 in this issue).
Behavior guided by spectral cues
In Drosophila, dual choice assays were employed to analyze the innate preference of walking flies for monochromatic light against darkness ('phototaxis'), and to analyze how flies choose between two spectrally distinct lights ('differential phototaxis' or 'spectral preference'). Both paradigms revealed positive phototaxis from 250 to 650 nm with two maxima, one in the blue and one in the UV wavelength range (Bertholf 1932; Fingerman and Brown 1952; Schümperli 1973; Harris et al. 1976; Hu and Stark 1977). When testing phototaxis to UV light of increasing intensity, Drosophila preference increases until it saturates at medium intensities. With green light, preference similarly increases up to medium intensities, but decreases and even turns into avoidance at higher intensities (Jacob et al. 1977; Fischbach 1979; Gao et al. 2008). Thus, in Drosophila, phototactic behavior is not purely achromatic as it does not exclusively correlate with the intensity of light. Instead, it also depends on the wavelength of presented light and can therefore not be the result of a simple summation of photoreceptor responses. A dependence of phototaxis on the spectral composition of light has further been observed when flies could choose between UV and a mixture of green and UV light (same intensity of UV in both stimuli, i.e. pure UV stimulus in all experiments is darker than the mixture). In these experiments, flies preferred the spectrally mixed stimulus at low UV intensities and the pure UV stimulus at high UV intensities (Heisenberg and Buchner 1977; Fischbach 1979). Altogether, phototaxis in Drosophila involves both chromatic and achromatic discrimination. Differentiating between the two in spectral preference experiments with monochromatic stimuli has hitherto not been feasible.
The ecological function of the observed phototactic behavior of Drosophila is not known, it may serve orientation behavior towards open space. This assumption largely rests on fact that UV is typically more prominent in the open sky compared with UV reflectance from objects in the ventral half of the field of view (Möller 2002). In line with this assumption, female Drosophila orient towards UV light when there is no demand to lay eggs. However, to lay eggs, flies turn away from UV light to lay them on dark substrate (Zhu et al. 2014; Guntur et al. 2017). Thus, phototaxis can depend, at least in mated females, on the internal state. A recent study furthermore suggests that phototaxis in addition depends on the time of the day (Lazopulo et al. 2019). This was observed when analyzing spectral preference of Drosophila between blue, red, and green illuminated areas using light intensity levels much higher than in all previous studies. Under these conditions, Drosophila showed a strong preference for green in the early morning and late afternoon, reduced preference for green at midday and robust avoidance of blue throughout the day (Lazopulo et al. 2019). It is still somewhat unclear whether these two behaviors (UV avoidance in the context of egg laying and the change of spectral preference during the course of the day) depend on the analysis of spectral content. In honey bees, phototaxis solely depends on the intensity of light (Kaiser et al. 1977; Menzel and Greggers 1985) (but see discussion below). In contrast, many innate behaviors that involve color vision have been reported in insects (Kelber et al. 2003). For instance, the butterflies Papilio aegeus and Pieris brassicae prefer to oviposit on green substrate, the hoverfly Eristalis tenax prefers to feed on small yellow objects and the ant Camponotus blandus exhibits a strong innate preference for UV over blue and green stimuli (Lunau and Wacht 1994; Kelber 2001; Yilmaz et al. 2017).
Color vision in Drosophila has also been studied using color conditioning paradigms in which the animals were trained to associate a color with either reward or punishment (Menne and Spatz 1977; Kelber et al. 2003; Tang and Guo 2001; Schnaitmann et al. 2010, 2013; Melnattur et al. 2014). In differential conditioning, one spectral stimulus is presented together with, for instance, sugar reward, while another spectral stimulus is presented without. After several rounds of training, flies can choose between the two color stimuli. If flies show a preference for the previously rewarded stimulus, one can infer that they can discriminate the two visual stimuli. Compared with spectral preference experiments, color conditioning greatly facilitates the analysis of intensity invariant stimulus discrimination in Drosophila. Changing or reversing the relative intensities of the visual stimuli between training and test in differential conditioning experiments allows to test whether the flies' choices are based on spectral properties or the intensity of the visual stimuli (Menne and Spatz 1977; Tang and Guo 2001; Schnaitmann et al. 2013; Melnattur et al. 2014). Using differential color conditioning, a wavelength discrimination function (Δλ/λ) was determined for Drosophila with two wavelength ranges where the capability to discriminate neighboring wavelengths is highest. In the violet (≈ 420 nm) and in the blue–green (≈ 495 nm) wavelength range, flies can discriminate stimuli that differ about 20 nm in wavelength (Hernández de Salomon and Spatz 1983). In their important pioneering study, Hernández de Salomon and Spatz (1983) tested only relatively few wavelengths and the missing analysis of UV excludes major sensitivities of the Drosophila compound eye (Fig. 2e). In addition, they used spectral preference behavior to reveal isoluminant stimuli. This approach is questionable because spectral preference itself depends on both spectral and intensity properties of stimuli. Thus, a potential contribution of intensity discrimination cannot be excluded. When compared with bees or butterflies, the obtained Δλ/λ values for Drosophila are rather large. Differential color conditioning experiments in freely flying honey bees revealed a Δλ/λ function with two optima, one in the violet (≈ 400 nm) and one in the blue–green (≈ 500 nm) wavelength range. However, bees were able to discriminate stimuli differing only 4–6 nm in wavelength (von Helversen 1972). An even more accurate and complex color discriminability was found in the butterfly Papilio xuthus. Using proboscis extension reflex (PER) conditioning (Koshitaka et al. 2008), the Δλ/λ function exhibits three optima at 420, 480 and 560 nm, respectively, and butterflies were able to discriminate stimuli as close as 1 nm apart from each other.
Importantly, color discrimination in Drosophila strongly depends on the precise design of the behavioral assay, and whether flies are agitated or undisturbed prior to behavioral decisions (Harris et al. 1976; Heisenberg and Buchner 1977; Jacob et al. 1977; Fischbach 1979; Gao et al. 2008). Dependencies on the behavioral assay were also observed in bees. Investigation of wavelength discrimination using either the proboscis extension reflex in restrained bees or behavioral decisions in freely moving bees as readout revealed much better wavelength discrimination in the latter (Niggebrügge et al. 2009). Also, differential conditioning yields better discrimination than absolute conditioning in bees (Giurfa 2004). If spectral discrimination in Drosophila also depends on the angular size of the presented stimuli remains unknown. In bees, discrimination relies exclusively on achromatic L-receptor contrast if stimuli are small (5°–15° of visual angle), whereas larger stimuli are discriminated exclusively based on chromatic contrast (Giurfa et al. 1996, 1997; Giurfa and Vorobyev 1998; Ng et al. 2018). Thus, more than ~ 60 neighboring ommatidia must be stimulated to enable object detection based on chromatic mechanisms in bees. In contrast, stimulation of only seven ommatidia enables object detection based on L-receptor contrast. These findings might also provide a simple explanation for experiments in which bee phototaxis behavior was found to be achromatic: the presented stimuli of 1–9.5° of angular size might have been too small to enable chromatic processing mechanisms to become active (Kaiser et al. 1977; Menzel and Greggers 1985). With respect to color vision research in Drosophila, it is important to note that spatial color contrast and color constancy, that are well documented in at least some insects including butterflies and bees have not been reported so far (reviewed in Chittka et al. 2014). In contrast, temporal color contrast is detected by Drosophila (Fischbach 1979).
Photoreceptor contributions to color vision
In the 1960s, Seymour Benzer pioneered the field of neurogenetics by isolating Drosophila mutants with deficits in phototaxis using chemical mutagenesis (Benzer 1967). Later, further mutants with impaired vision were isolated based on noticeable defects in electroretinogram recordings (Koenig and Merriam 1977). Specific structural and functional defects were assigned to in particular the mutants rdgBKS222, sevLY3 and oraJK84 that were used to reveal the contribution of photoreceptors to phototaxis and spectral preference (Harris et al. 1976; Heisenberg and Buchner 1977; Hu and Stark 1977; Jacob et al. 1977; Fischbach 1979). In oraJK84 and rdgBKS22, R1–R6 completely degenerated in the presence of light. In sevLY3, mutant R7 photoreceptors are completely absent due to a developmental defect. Studies based on these mutants suggested that all photoreceptors can contribute to phototaxis and spectral preference. However, it became clear that their contributions critically depend on the exact stimulus conditions. Spectral preference behavior to two monochromatic stimuli, with one as a constant reference and the other varied in intensity and wavelength, is mainly mediated by R7 and R8 (Hu and Stark 1977). In contrast, when spectral preference is tested with a 'white' reference stimulus, it involves all photoreceptor types (Schümperli 1973; Harris et al. 1976). Phototaxis experiments also revealed that R1–R6 have a higher absolute light sensitivity than R7/R8 (Harris et al. 1976; Jacob et al. 1977).
Years later, it was shown that sevLY3 causes uniform rh6 expression in all R8 photoreceptors in addition to the known R7 degeneration (Chou et al. 1999). oraJK84 turned out to be a double mutant with null mutations in ninaE (rh1) and ort (O'tousa et al. 1989). The previously unnoticed mutation in ort affects one of two histamine receptor genes of the Drosophila genome that is expressed widely in the fly visual system in all neurons downstream of all types of photoreceptors (Gao et al. 2008). Thus, the ort mutation included in oraJK84 strongly affects visual processing, in addition to the known absence of R1–R6 function. More recent studies that employed either specific mutations in individual rhodopsin genes or specific rhodopsin promoters to drive block of synaptic transmission in specific photoreceptor types overcome these problems. However, despite significant differences in the specificity of the approaches, the new studies largely corroborated the major findings of older work and demonstrated that each photoreceptor type (R1–R6, R7, R8) can drive spectral preference on its own (Gao et al. 2008; Yamaguchi et al. 2010).
Few studies addressed whether individual photoreceptor classes contribute to the chromatic aspect of phototactic behavior. Color mixing experiments revealed that sev mutants did not exhibit the wavelength dependent reactions to mixed UV/green stimuli that were exhibited by wild-type flies (see 'behavior guided by spectral cues', Heisenberg and Buchner 1977; Fischbach 1979). Furthermore, sev mutant flies did not show the negative phototaxis at high intensities of green light (Jacob et al. 1977). These findings suggest that R7 has a prominent role in the chromatic aspect of phototactic behavior.
Based on their broad-band sensitivity and major role in motion vision (Heisenberg and Buchner 1977; Yamaguchi et al. 2008; Wardill et al. 2012), R1–R6 were thought not to contribute to fly color vision (Troje 1993). This view was challenged by the finding that Drosophila color discrimination is described best using a receptor noise-limited model that incorporates R1–R6 (Hernández de Salomon and Spatz 1983; Schnaitmann et al. 2013; Garbers and Wachtler 2016). Most importantly, flies with R1–R6 and R7y as only functional photoreceptors are able to discriminate blue and green (Schnaitmann et al. 2013). This finding rests on experiments combining genetic interference with photoreceptor function and appetitive color conditioning. However, it turned out that R1–R6 are not required in general for this specific spectral discrimination: flies with function restricted to R7y and R8y were also able to discriminate blue and green, whereas flies with function restricted to R1–R6 and R8y failed. These experiments suggest that fly color vision involves comparisons between R1–R6 and R7y as well as R7y and R8y. This conclusion is in line with the involvement of R7 in the chromatic aspect of phototaxis (see above). Flies with function restricted to R1–R6, R7p and R8p were not able to discriminate blue and green. To further explore the role of photoreceptor types in Drosophila color vision, the range of the wavelengths that are analyzed in spectral discrimination tasks must be extended. In particular, it remains to be addressed whether also the photoreceptors of pale ommatidia are involved in the discrimination of shorter wavelengths, as suggested by work in Lucilia (Troje 1993).
Color discrimination in bees involves all photoreceptor types, and computational models including all three photoreceptor types explain behavioral observations well (Neumeyer 1980; Backhaus et al. 1987; Backhaus 1991; Chittka 1992; Brandt and Vorobyev 1997; Vorobyev et al. 2001). Electrophysiological recordings in the bee visual system revealed a large diversity of different color opponent response types, and modeling work demonstrates that all three photoreceptor types are involved (Kien and Menzel 1977a, b; Hertel 1980; Yang et al. 2004; Paulk et al. 2008, 2009a, b; Vasas et al. 2019). In contrast, color discrimination in Papilio xuthus does not involve all of its six 'spectral classes' of photoreceptors (Koshitaka et al. 2008). The Δλ/λ function of these butterflies exhibits three optima that are interpreted as evidence for three photoreceptor opponent computations in color vision. A receptor noise-limited color opponency model including UV, blue, green, and red photoreceptor sensitivities yields the best fit to the Δλ/λ function (Koshitaka et al. 2008; Arikawa 2017).
Circuit mechanisms underlying color vision
Physiological studies that include detailed investigations of the identity, function and nature of synaptic and circuit interactions in insect color vision are still rare. Until recently, this included the physiology of insect photoreceptor terminals that were uncharted territory (see below). Intracellular recordings from distal segments of photoreceptors of many insect species showed positive membrane potential changes; only few studies reported additional evidence for spectral inhibition. Seldom encounters of additional negative interactions have been reported in bees where some of the recorded UV receptors depolarized at short wavelengths and hyperpolarized at wavelengths longer than 420 nm. Comparable hyperpolarizing responses have been observed in some UV- and B-receptors in bumble bees (Skorupski et al. 2007). Why such hyperpolarizing responses were only observed in few of the recordings remained unknown. Most photoreceptors were excited over a wavelength range broader than expected from rhodopsin sensitivity (Menzel and Blakers 1976). Moreover, the spectral inhibition was absent when recordings were made in axons in the lamina instead of outer photoreceptor segments. These axonal recordings revealed 'pure single pigment spectral sensitivity', which led the authors to conclude that positive and negative interactions cancel each other (Menzel and Blakers 1976).
Clear evidence for inhibitory photoreceptor interactions in insects comes from experiments in few butterfly species where a fraction of the recorded photoreceptors exhibited hyperpolarizing responses to light (Horridge et al. 1983; Matić 1983; Chen et al. 2013). In these intracellular recordings, the reference electrode was usually placed in the body cavity and Matić (1983) showed that many of the hyperpolarizing interactions were strongly reduced or turned into excitation when the reference electrode was placed in the extracellular space close to the recording electrode. He explained this observation by the presence of strong light-induced fluctuations of the extracellular potential of up to 60 mV (Matić 1983). However, because inhibition was retained in some of the recordings, Matić concluded that inhibition between photoreceptor is not a methodological artifact and that butterflies make a special case.
New insights came from a recent study in Drosophila. Two-photon calcium imaging with subcellular resolution revealed UVshort vs. blue and UVlong vs. green opponent processing in the terminals of R7p/R8p and R7y/R8y, respectively (Schnaitmann et al. 2018). These first color opponent interactions in the fly visual system rely on mutual inhibition between R7 and R8 of either type of ommatidia. Notably, this spectral inhibition is mediated by two mechanisms that act in parallel. First, the Drosophila histamine-gated chloride channel HisCl1 is expressed in inner photoreceptor terminals and mediates direct reciprocal synaptic inhibition between R7 and R8 of the same ommatidium (mutual inhibition within a single column). Second, R7 and R8 receive spectral feedback signals from neurons in the medulla that express the second Drosophila histamine receptor Ort, in particular from the multi-columnar Dm9 cell as revealed in recent work of our laboratory (Fig. 4b) (Schnaitmann et al. 2018; manuscript in preparation). These two mechanisms are of different importance in R7 and R8: in R7, either of the mechanisms is sufficient for color opponent processing, whereas in R8 both mechanisms are required and must act together for detectable color opponency (Schnaitmann et al. 2018). Inhibitory photoreceptor responses, synaptic contacts between photoreceptors, and expression of PxHCLB, the homolog of Drosophila HisCl1in Papilio xuthus suggest that related neuronal mechanisms underlie early color opponent processing in butterflies and flies (Takemura and Arikawa 2006; Takemura et al. 2013; Schnaitmann et al. 2018; Chen et al. 2019). Differences between Drosophila and butterflies exist in the precise site where interactions take place. In Drosophila, HisCl1-mediated photoreceptor interactions are restricted to the distal three layers m1–m3 of the medulla (Schnaitmann et al. 2018). In Papilio xuthus, the major site of PxHCLB expression is the lamina with additional neuronal expression in the medulla. Furthermore, vfs as well as svfs express the histamine receptor PxHCLB and inter-photoreceptor connectivity is more complex than in Drosophila (Chen et al. 2019).
The pale and yellow specific spectrally opponent processing mechanisms in Drosophila's R7/R8 terminals match the opponencies that were suggested to underlie color discrimination in Lucilia (Troje 1993), and are in line with the finding that R7y/R8y are sufficient for blue–green discrimination in Drosophila (Schnaitmann et al. 2013) (see above). Together, these findings suggest that color vision in Drosophila involves UVshort/blue and UVlong/green color opponent pathways and that these pathways emerge already at the photoreceptor level. Thereby, processing in inner photoreceptor terminals very likely is the first of a series of sequential color opponent processing steps that remain to be revealed. Further color opponent processing steps in higher-order visual neurons are also suggested when the results from two-photon calcium imaging and behavioral experiments are compared. Functional imaging revealed no evidence for the integration of R1–R6 signals at the level of R7/R8 terminal responses (Schnaitmann et al. 2018). However, a contribution of R1–R6 and of their downstream neurons L1 and L2 to color discrimination has been demonstrated in a behavioral study (Schnaitmann et al. 2013; Garbers and Wachtler 2016). Therefore, the signals of R1–R6 must be integrated into the Drosophila color vision circuitry downstream of R7/R8 terminals. Combined genetic, anatomical, and behavioral studies suggest that R1–R6 signals are conveyed via L2 and/or L3 to Tm5 subtypes and Tm20, neurons that are directly downstream of R7/R8 (see below and Fig. 4). Whether these neurons indeed generate color opponent responses that are in line with indirect input from R1–R6 remains to be revealed by physiological recording.
To this date, the function of neurons downstream of R7/R8 in color vision has been addressed by combining promoter- or cell-type-specific genetic targeting with anatomical characterization, connectivity analysis, functional perturbation, and behavioral analysis (Gao et al. 2008; Karuppudurai et al. 2014; Melnattur et al. 2014). In a pioneering study, Gao et al. (2008) identified neurons that are postsynaptic to R7/R8, including several candidate neurons of the color vision circuitry. Because arthropod photoreceptors release histamine as sole neurotransmitter (Hardie 1989; Stuart 1999), the authors reasoned that direct synaptic interactions with second-order interneurons should be mediated by the inhibitory histamine-gated chloride channel Ort that is widely expressed in the lamina and medulla of the fly visual system (Witte et al. 2002; Pantazis et al. 2008). Comparison of ort-promoter activity with the stratification of axonal endings of R7/R8 revealed candidate neurons postsynaptic to R7/R8. Subsequently, synaptic connectivity was thoroughly confirmed using genetic labeling techniques (GRASP or derivatives thereof) and serial electron microscopic reconstructions (Gao et al. 2008; Takemura et al. 2013; Karuppudurai et al. 2014; Takemura et al. 2015). This resulted in the identification of the transmedulla projection neurons Tm5a/b/c, Tm9 and Tm20, and the multi-columnar amacrine neuron Dm8 (Fig. 4). Tm5a/b/c, Tm9, and Tm20 receive direct and/or indirect input from inner photoreceptors. Some of them additionally receive indirect input from R1–R6 via the lamina monopolar cells L2 and/or L3 (Takemura et al. 2013, 2015). Of these neurons Tm9 was later associated with motion vision, as it conveys information to T5 and is therefore part of the OFF-edge motion detection pathway (Shinomiya et al. 2014; Serbe et al. 2016).
Dm8 and Tm5c neurons have a central function in UV/green spectral preference. Dm8 is postsynaptic to R7, has multi-columnar organization, and expresses Ort. Individual Dm8 cells pool 'UV input' from 12 to 16 R7 photoreceptors of neighboring ommatidia and conveys it to all Tm5 subtypes, as well as unknown neurons (Gao et al. 2008; Karuppudurai et al. 2014; Menon et al. 2019). Blocking synaptic output of glutamatergic Dm8 results in reduced preference for UV, whereas flies with restored Ort receptor function in exclusively Dm8 (cell specific Dm8 rescue in ort mutant flies) exhibit intact spectral preference behavior (Gao et al. 2008). Knock-down of kainate glutamate receptors in postsynaptic Tm5c reduces preference to UV, suggesting that direct input from Dm8 to Tm5c is important. In line, flies with blocked synaptic transmission in Tm5c show defects in spectral preference comparable to flies with blocked synaptic transmission in Dm8 (Karuppudurai et al. 2014). Furthermore, Ort expressing Tm5c receive direct synaptic input from R8 and this input contributes to preference for green. Altogether, the R7–Dm8–Tm5c pathway is necessary and sufficient to mediate UV spectral preference against green light.
In addition to its role in UV/green spectral preference behavior, Tm5c together with other Tm cell types contributes to blue/green discrimination in a conditioning assay (Melnattur et al. 2014). Simultaneous block of Tm5a/b/c, and Tm20, but not of single cell types or combinations of them is required for complete loss of blue–green color discrimination (Melnattur et al. 2014). Therefore, Tm5a/b/c, and Tm20 are thought to represent redundant pathways of the color vision system. These neurons convey jet unknown information to visual projection neurons in the deep strata of the lobula that project to the central brain (Otsuna and Ito 2006; Lin et al. 2016; Panser et al. 2016; Wu et al. 2016). The lobula intrinsic neuron Li4 makes many synaptic contacts with almost all Tm5a/b/c and Tm20. LT11 is less connected with most of the Tms, apart from extensive Tm5a input (Lin et al. 2016). Blocking synaptic transmission in LT11, a single neuron per hemisphere that receives input from the entire visual field and therefore cannot convey retinotopic information, caused defective phototaxis specifically in the range of 410–440 nm (Otsuna et al. 2014). The same study identified another type of visual projection neuron, MC61, that projects from the medulla to the anterior optic tubercle, bypassing the lobula. Blocking its synaptic output caused a phototaxis defect in the green and UV wavelength range (Otsuna et al. 2014). Also, recent research on associative visual information processing in Drosophila revealed direct pathways from the medulla to the central brain (Vogt et al. 2014, 2016). These VPNs project to the mushroom body, a prominent brain structure involved in associative memory. Thereby, different subpopulations of VPN are required for memories of color (VPN–MB1) and brightness (VPN–MB2) (Vogt et al. 2014, 2016).
At present, it is unknown whether or how the p–y dichotomy that has been observed in R7/R8 presynaptic terminals is retained in the pathways of the Drosophila color vision system (Schnaitmann et al. 2018). Anatomical data show that Tm5a, which is found exclusively in y columns, receives input from R7y but not R7p, and that Tm5b receives predominately input from R7p (Fig. 4c) (Karuppudurai et al. 2014; Menon et al. 2019). In contrast, Tm5c appears to pool p and y inputs (Fig. 4c). Recently, genetic and molecular methods enabled new insights into the specification of Dm8 cells. Analysis of the expression of the surface molecules of the Dpr and DIP family suggests that different flavors of Dm8 exist that likely correspond with p and y subtypes. Dpr11 is selectively expressed in R7y that contact a subpopulation of Dm8 that in turn express the Dpr11 interaction partner DIP-γ; absence of these interaction partners characterize R7p and another subpopulation of Dm8 (Carrillo et al. 2015; Tan et al. 2015; Menon et al. 2019).
What kind of color-coding physiological response types can be expected in second- and higher-order visual interneurons in Drosophila? To speculate on this question, a look at color vision in bees may provide important suggestions. Early studies on bee color vision suggested a small number of color opponencies that are likely established by deterministic wiring of the three types of photoreceptors to postsynaptic neurons. However, electrophysiological examination so far revealed a large diversity of color opponent responses with different spectral tuning (Menzel and Blakers 1976; Kien and Menzel 1977a, b; Hertel 1980; Yang et al. 2004; Paulk et al. 2008, 2009a, b). This unexpected diversity might be explained by partially random wiring of photoreceptors to postsynaptic color opponent neurons in the medulla and lobula (Vasas et al. 2019). It would also help to explain why receptive fields with a spatially antagonistic organization have not been reported so far in bees (Kien and Menzel 1977a, b; Hertel 1980). In Drosophila, it is now time to reveal the diversity of color opponent neural cell types in the medulla and lobula, the spatial layout of their receptive fields, the underlying cellular wiring, and the molecular implementation of identified computations. We expect this research to provide conceptually new insights into the neuronal basis of color vision in insects and important visual phenomena like spatial and temporal color contrast and color constancy. The recent connectomics and RNAseq data of the medulla and its cell types will fuel this research (Takemura et al. 2013, 2015; Tan et al. 2015; Konstantinides et al. 2018).

Terraforming (literally, "Earth-shaping") of a planet, moon, or other body is the hypothetical process of deliberately modifying its atmosphere, temperature, surface topography or ecology to be similar to the environment of Earth to make it habitable by Earth-like life.
The concept of terraforming developed from both science fiction and actual science. The term was coined by Jack Williamson in a science-fiction story (Collision Orbit) published during 1942 in Astounding Science Fiction, but the concept may pre-date this work.
Based on experiences with Earth, the environment of a planet can be altered deliberately; however, the feasibility of creating an unconstrained planetary environment that mimics Earth on another planet has yet to be verified. Mars is usually considered to be the most likely candidate for terraforming. Much study has been done concerning the possibility of heating the planet and altering its atmosphere, and NASA has even hosted debates on the subject. Several potential methods of altering the climate of Mars may fall within humanity's technological capabilities, but at present the economic resources required to do so are far beyond that which any government or society is willing to allocate to it. The long timescales and practicality of terraforming are the subject of debate. Other unanswered questions relate to the ethics, logistics, economics, politics, and methodology of altering the environment of an extraterrestrial world.
Terraform is the second full length record by Shellac, released in 1998.

So, what are the big wins of vertical aquaponics? How can you start one at home? What plants and fish work best for this method? Also, how does it stack up against aeroponics?
In this article, we'll explore vertical aquaponics and its benefits. We'll look at its role in cities and give tips on building your own system. Get ready to elevate your farming experience!
Stay tuned to discover how vertical aquaponics can change the game in farming. It saves space and resources while boosting crops.
The Rise of Vertical Farming in Sustainable Agriculture
Vertical farming is changing how we grow food. It's a new way to farm that uses less land. This is important as the world's population grows and land becomes scarce. Vertical farming helps by using space wisely in cities.
The Concept and Evolution of Vertical Farms
Vertical farming changes farming from the ground to the sky. Instead of large fields, it uses vertical space. This means we can grow more food in smaller areas, indoors.
Vertical farms use tech to control the environment perfectly. This tech ensures plants grow well under ideal conditions. It makes it possible to grow food all year round, with great quality.
Integration of Controlled Environment Agriculture (CEA) Technologies
CEA technologies are key to vertical farming. They use AI and data to keep plants growing perfectly. This tech fine-tunes the climate and nutrients for the plants. So, we use resources better and get healthy plants.
Global Population Growth and Urbanization Challenges
The world's population is growing fast, and cities are getting crowded. This makes farming land hard to find. Vertical farming can help by using city spaces like warehouses for farming.
Vertical farming also protects our environment. It reduces the need to move food far, cutting down pollution. By using less water and chemicals, it makes farming better for our planet.
Vertical farming is shaping the future of farming. It uses space better, combines high-tech systems, and solves big challenges. It's a bright path for feeding people in a sustainable way.
Maximizing Space and Efficiency: The Core of a Vertical Aquaponics System
At the core of a vertical aquaponics system is smart use of space while being efficient. These systems stack plants and fish vertically. This makes great use of small spaces.
Vertical aquaponics systems can grow more in less space than regular farms. This is great for cities where space is tight. They also use water and nutrients wisely, creating less waste and more growth.
The design of a vertical aquaponics system is crucial for its success. It's important to plan how to use light, water, and space well. A good design means a productive and green farm.
Vertical aquaponics systems are a key to sustainable food growing. They work well in cities or at home. These systems are a smart choice for growing food without harming the planet.
Optimizing Crop Production in Urban Landscapes
Vertical agriculture is changing the game in city farming. Cities often struggle with space for traditional farming. But vertical gardening using aquaponics is a great way for people and groups to grow food in urban areas.
Vertical Gardening with Aquaponics in Cities
Vertical gardening uses up high spaces to fit many plants in a small spot. Mixing this with aquaponics, which combines fish and plant farming, creates a system where each helps the other. The plants get all the nutrients they need from the water that comes from the fish tank, helping them grow quicker.
Growing food with vertical aquaponics can happen in many city spots like rooftops or even indoors. This way, city dwellers can get past the issue of not having enough space. They can enjoy fresh food that they grow themselves.
Artificial Intelligence and Smart Monitoring in Aquaponics
Adding artificial intelligence (AI) and smart monitoring has made aquaponics even better. AI can watch and tweak important things like the water's temperature or nutrient levels. This helps keep the plants and fish growing well.
Smart monitoring gives us updates and info in real-time. This lets city farmers know how their crops are doing right away. They can fix any problems fast. This technology is a big help.
The Role of Aquaponics in Food Security and Urban Planning
Aquaponics is very important for food security in cities. It lets food be grown locally, making cities less dependent on outside food sources. This method also produces very healthy and nutritious food, which is great for everyone in the city.
It also fits into urban planning by helping create strong, self-reliant communities. By adding vertical aquaponics into city designs, we can use land and resources smarter. This approach encourages sustainable living and helps with food security too.
To wrap it up, vertical gardening and aquaponics, with the help of AI and smart tech, offer a smart way to farm in cities. It lets people and communities grow their own food even in small spaces. This approach is key to having secure food sources and sustainable cities in the future.
Hydroponics, Aeroponics, and Aquaponics: Comparing Growth Mechanisms
Hydroponics, aeroponics, and aquaponics are three innovative systems. Each has unique features and benefits. They offer new ways to grow plants and vegetables sustainably.
Hydroponics grows plants in a water solution full of nutrients, not in soil. It gives plants exactly what they need to grow well. This method saves space and water, which is great for cities.
Aeroponics hangs plants in air and sprays them with nutrients. This way, roots get plenty of oxygen and nutrients. It uses water very efficiently, and plants grow faster and yield more.
Aquaponics mixes fish farming with hydroponics in a closed-loop system. Fish waste turns into plant food, and plants clean the water for the fish. It's a sustainable cycle, using resources with little waste.
Each system has its own advantages. Hydroponics is great for controlling nutrients and saving space. Aeroponics is top for water use and quick growth. Aquaponics combines fish and plants in a self-sustaining system.
Choosing the right system depends on your needs. Knowing about hydroponics, aeroponics, and aquaponics can help. They each contribute to farming's sustainable and efficient future.
Diving Into DIY Vertical Aquaponics Systems: A Step-by-Step Guide
Getting started with DIY vertical aquaponics is exciting. It lets people grow their own food at home. You can start whether you have just a small balcony or a big backyard.
Designing Your Vertical Aquaponics Setup at Home
First, look at the space you have. Figure out how big your system should be. Think about the containers, pipes, pumps, and beds you'll need. Make sure everything you choose is safe for food and works well with aquaponics.
Then, think about your system's design. Do you want a tower or a wall setup? Each has its benefits. Pick what fits best with your space and what you like.
Don't forget about water flow and cleaning. You need a fish tank, a filter, and a pump. This helps keep water moving between the fish and the plants.
Selecting the Best Plants and Fish for Vertical Aquaponics
Choosing the right plants and fish is key. You need to think about what each needs, like temperature and pH level.
For plants, go for ones that don't need much room and have small roots. Lettuce, spinach, and kale are great. You can also grow herbs like basil and mint to add flavor to your food.
For fish, tilapia, trout, and catfish are common picks. Learn about what each fish needs. Make sure they match well with your plants.
Maintaining the Vertical Ecosystem: Tips and Tricks
Keeping your system healthy takes regular check-ups. Watch the water, nutrients, and system parts. This helps your plants and fish grow well.
Feeding the fish just right is important. Too much food can harm the water. Keep an eye on the water's quality and change things as needed.
Managing water is vital. Check the water often and keep it oxygen-rich for the fish. Think about using an aeration system to help.
Also, watch out for pests like aphids or snails. Act fast to stop any problems. Do this, and your aquaponics system can thrive for a long time.
With these tips, you'll keep your DIY vertical aquaponics system running well.
Vertical aquaponics systems have many benefits for green farming. They tackle the problem of using small spaces well. This way, they boost the amount of crops grown without needing more land.
They work by stacking plants on top of each other. This method allows more crops to grow in less space. It's a smart option compared to old farming ways.
With new tech, vertical farming is becoming more popular. Vertical aquaponics looks to be a big help for food supplies and keeping our planet healthy. It's also good for city food growth plans.

New Paper: CRA Small Business Lending And Employment
Posted by on September 10, 2010
Small businesses are the driving force behind job creation, yet many struggle to find the capital they need to survive and grow. Women and minority-owned businesses face additional impediments. Today, we're pleased to announce a new National Community Reinvestment Coalition (NCRC) study, "Does CRA Small Business Lending Increase Employment: an Examination on a County Level."
The study looks at over 500 counties around the country, exploring the national impact of the Community Reinvestment Act (CRA) on small business lending (CRA motivates banks to make loans to small businesses by examining the extent to which banks are making loans to small businesses). The study can be downloaded at: http://bit.ly/9iYAqC.
Study Findings
The study shows a positive correlation between small business lending and employment. The study also reveals troubling racial inequalities in small business lending. In fact, our analysis finds that counties with greater percentages of minorities had lower rates of small business lending and employment.
The NCRC study looked at 2006 lending data for dozens of counties around the country. Some of the specific findings in NCRC's study include:
* There is a positive correlation between small business lending and employment; the more small business lending in a county, the higher the employment rate.
* Almost 55 percent of the small businesses studied received loans in counties with less than 20 percent African Americans. This ratio declined to 48 percent in counties with 30 percent or more African Americans, on average.
* Employment rates are lower in counties with higher percentages of minorities and African Americans. The average employment rate is 2 percentage points higher for counties with less than 20 percent African Americans than in counties with more than 30 percent African Americans.
If you have any questions about the study, please feel free to contact , Josh Silver, NCRC Vice President of Research, at 202-628-8866.

- Virginia City
a mining town in W Nevada: famous for the discovery of the rich Comstock silver lode 1859.
* * *
town, seat (1876) of Madison county, southwestern Montana, U.S., on the Ruby River. Founded as Verona (after Varina Davis, wife of the president of the Confederate States of America) in 1863, when gold was discovered in nearby Alder Gulch, it was the first town to be incorporated (1864) in Montana and was the territorial capital from 1865 to 1875. The mines are no longer productive but the town has been reconstructed in the style prevalent during the days of the gold rush. Restored buildings include the offices of the Post, Montana's first newspaper (issued August 27, 1864). Pro-Northern vigilantes organized there in the 1860s and assassinated several residents, including the sheriff of the Bannack Mining District, suspected of sympathizing with the Confederate cause. The city was renowned for violence long after the end of the Civil War. Tourism, supplemented by livestock raising, is the economic mainstay. In the summer, 19th-century drama and vaudeville shows can be seen in the Opera House. Nevada City, just west, is also a reconstructed gold camp. Pop. (1990) 142; (2000) 130.unincorporated town, seat (1861) of Storey county, western Nevada, U.S., on the eastern slope of the Sierra Nevada range, 20 miles (32 km) south of Reno. Settled in 1859 and named for a prospector, "Old Virginia" Fennimore, it became a booming mining camp after the discovery of the Comstock Lode (chiefly silver) on nearby Mount Davidson. When the Nevada Territory was created by Congress in 1861, Virginia City had more than three-fourths of the new territory's population. In the 1870s its population reached 30,000, and there were 6 churches and more than 100 saloons. In 1875 the town was devastated by a fire that destroyed 33 blocks, including the entire downtown district.The "bonanza barons," such as George Hearst and John MacKay, who made millions in the mines, built Victorian-style mansions, and even public buildings were elaborately decorated. A reporter on the city's newspaper, the Territorial Enterprise, during its boom period was Samuel Clemens, who first signed his well-known pen name, Mark Twain (Twain, Mark), to one of his newspaper stories. Bret Harte (Harte, Bret), another notable writer, also worked on the paper during Clemens's time there.After 25 years of frantic mining activity, Virginia City's population dwindled as the ore was worked out in the 1880s. It nearly became a ghost town, although in 1935 new federal controls on the price of gold spurred a modest revival that included the paving of Virginia City's main streets. The remaining 19th-century businesses—mainly saloons and popular museums—and some old mansions are maintained for the tourist trade. The Virginia and Truckee Railroad (1869), which tapped the Comstock, has been partially restored. The area has been designated a national historic district.* * *

Fuel Catalysts & Archoil's AR6200 / AR6900-D MAX
by Andy Published on Friday, January 24th, 2014
We regularly receive questions regarding fuel catalyst technologies and how they work. In particular, we receive many questions about Archoil AR6200 and AR6900-D MAX. The existing definition of "burn rate modifier" and the phrase "lowers burn rate by up to 400 degrees" has caused confusion.
In simple terms, a catalyst facilitates a better burn of the fuel. Each fuel type will have a flash point and auto-ignition point, which are determined by temperature and other factors. But these are different from the burn rate.
Both petrol and diesel are composed of carbons and these carbons, or carbon chains, require up to 1200ºF to burn thoroughly. This has nothing to do with the flash point. The flash point is the temperature at which the vapor of the fuel will ignite with the help of an ignition source. The auto-ignition point is the temperature at which the fuel vapor will ignite without an ignition source.
Once the fuel has ignited, it creates an exothermic reaction (heat). This rapid increase in heat burns the fuel (carbons) and establishes the explosion in the combustion chamber, thus resulting in a massive release of energy. This forces the piston downwards and causes the crankshaft to rotate.
If you can reduce the temperature at which the carbons burn, say by up to 400ºF in the case of AR6200, you can improve the burn. This is achieved by increasing the surface area of fuel droplets and starting the burn rate of hydrocarbons at a lower temperature to yield more available BTUs from the combustion process. The fuel becomes more aromatic (a sign of increased chemical stability), and a longer residual burn occurs. By commencing the burn rate lower, the lower-end hydrocarbons are burnt, and the combustion process is more residual and complete. This practically eliminates unburned hydrocarbons and wasted energy in the form of black smoke or emissions.
Altering the burn rate in this way does not directly increase horsepower. It increases the energy released through the explosion, which raises torque output. Burning the fuel more fully will also increase torque and lower emissions, as proven by the AR6200 carbon mass balance tests. This is the same process with all hydrocarbon fuels such as petrol, diesel, ethanol, heating oil, heavy fuel oil, etc.
Now, you might wonder, will AR6200 affect the octane rating of petrol?
We have proven with ASTM D2699 tests that there is no change. Octane is simply a measurement of when gasoline will automatically ignite. Increases in cylinder pressures and temperatures can make the fuel ignite prematurely, thus creating the dreaded engine knock/pinging sound. Octane boosters or anti-knock additives reduce the volatility of fuel so that it ignites as instructed via a source of ignition rather than on its own.
AR6200 only affects the temperature at which the carbons will burn once the fuel has ignited. It does not directly alter the flash or auto-ignition point. However, tests have shown that the improvement in combustion quality and stability means that the propensity of pre-ignition is reduced with AR6200. And this can have the effect of "raising" the octane. However, this cannot be demonstrated with a simple D2699 knock engine.
But isn't this contradictory? Not really. When fuel is not entirely burned it can leave pockets of fuel that subsequently ignite a second time, again causing engine knock. The improvement in combustion quality from using AR6200 helps eliminate this because all fuel carbons are burned entirely the first time. AR6200 is not altering the auto-ignition point of the fuel but instead correcting another inherent source of engine knock – remaining unburned fuel.
We hope this helps and if you require any advice, please don't hesitate to contact us; either I or a member of my team will be pleased to assist you.
60 thoughts on "Fuel Catalysts & Archoil's AR6200 / AR6900-D MAX"
Having an older 2009 Peugeot 807 2.0 HDI in my garage, a Euro4 DPF and EGR equipped vehicle that is using a additive tank with automatic additive dosing to the diesel fuel, called EOLYS.
Is it still advisable to use the 6900D-Max combustion catalyst? From what I've read the EOLYS is Peugeot's own catalyst.
I dont want to introduce any unknown side effects.
mileage is at 230.000 miles now, original diesel pump, previous owner was a 2 stroke 200:1 to diesel fuel advocate.
Yes. AR6400-D will convert standard diesel into premium and better. It will not have any negative impact on the function of the Eolys fluid.
Im interested in using Archoil AR6915 which is designed for bulk fuel. 3000:1 ratio.
Will it still deliver benefits like AR6900dmax?
I'm worried about ferrocene, could it cause dpf blocking, or injector hole blocking? Any other adverse effects?-
It will only deliver one third of what AR6900-D MAX will provide.
So what exactly does 6900D-Max better?
The AR6915 you say only does 1/3d of the 6900 DMax?
The 6915 according to its product information sheet has fuel catalyst, lubrication, cleaning and stabilizing as well as water seperation properties.
The 6900 DMax has about the same functions.
AR6915 is mixed at 1:3000, 6900Dmax at 1:1000.
According to the MSDS both products contain 2EHN, Lubrication, Ferrocene (as catalyst?).
The difference is for example that AR6915 has <5% ferrocene, 6900DMax <1% ferrocene.
So it seems to me that both products deliver the same benefits but AR6915 has more active ingredients, for example Xylene, as cleaner I suppose, which 6900 DMax hasn't according to its MSDS.
Not only has AR6915 more ingredients but more concentrated as well, see ferrocene content. So that gives a treatment ratio of 1:1000 for 6900 Dmax vs 1:3000 for AR6915.
AR6915 says its EN590 Compatible as well as compatible with Euro5/6 Diesels.
Both products contain a lot of 2EHN.
So it would be interesting for me to see what is the 2/3 extra that 6900 Dmax does that AR6915 doesn't?
You have made many assumptions that are incorrect. AR6915 is a trade only product designed for bulk fuel for customers looking for convenience and the ability to meet a price point. I know as I designed it. At 3,000:1 there are compromises such as a limit to the amount of 2-EHN so your assumption is incorrect as it delivers less than a 1/3 of that in AR6900. However, this is acceptable to the target market, which is mainly fleet. Also, Xylene is not a cleaner – components are added to aid solubility of functions within the fuel. There is no compromise with AR6900-D and in order to achieve this we need to deliver 1000ppm of active ingredients/functions. It too is fully concentrated with a revised detergent pack and lubricant that is very different in the latest 2020 version.
Well I ordered the AR6915 to trat bulk fuel for a small farm and a Diesel powered boat – and therefore I was interested to see wether the AR6915 is usable for my Euro6 car as well – or if I'm better of with 6900D-Max.
From my point of view – and as you see I'm only a interested end user who has an interest in oil, oil additives and generally everything mechanical, the thing I'm most interested with the Archoil is the combustion catalyst and it's functions for the DPF.
I recently aquired an Euro6 Diesel car with DPF and AdBlue Nox reduction catalyst, coming from an Euro4 french car.
Now the way I use the car is mostly highway use – but it has to sustain short tripping as well. And therefore, from the experience with my french car which uses Eolys, as far as I've researched a cerium oxide additive for lowering regen temps, I ended up with archoil.
Further research it seems that ferrocene is the ingredient in Archoil that does what cerium does in the Eolys. With the french additive DPF I never had a single issue, even with the shortest short tripping – unlike with non additive equipped DPF cars.
Now the 2 EHN and the cleaning are nice side benefits, but for me the ferrocene in combination with the 2EHN is the real deal. Lowering soot burning temperature and aiding passive regen to help maintain DPF performance.
I have the 5l container. Mostly I'm looking for the Ferrocene performance in aiding the dpf. Not so much for lubrication or cetane boost.
Checked my euro6 dpf today, active regeneration every 90 miles, new car with 700 miles and already had 8 active dpf regens. Unbelievable.
Just checking our records and AR6915 is supplied with or without catalyst. You may have a catalyst free version.
Is there any way to determine wether I have the AR6915 with or without the catalyst?
Any side effects of combining 6915 with 6900D-Max?
I ordered 6900 D-Max and still have about 4l of 6915 left.
Hi, please email a picture of the label to email@example.com. They cannot be combined as AR6900-D uses the latest ester lubricant and newer generation detergent pack.
AR6200 is absolutely awesome – been using it for 6 years on Z4 3.0si sport coupe straight 6cyl with 53K miles on the clock.
I've had an unbelievable 48.3 mpg on a 215 mile trip using standard unleaded + AR6200 + perfect road conditions, although it was a rolling start on the mpg reset at about 15mph. It was reading 48.7 at one point and was hoping to eek out 49mpg on the display – but dropped to 48.3mpg when I turned off the engine. On driving around town at the destination and coming back, it dropped to 45mpg because i occasionally cained it here and there. Driving style on out trip was economy mode, i.e. seldom stopped at roundabouts, lorries overtaking me occasionally but would pass them again… Speed was 50 – 70 mph on motorways. Avg speed was 49mph. Total trip: 458 miles.
Same driving style – and similar conditions before I started using AR6200 – I would get about 41.5mpg – although this is when the car only had 8000 miles on it.
QUESTION: would I be better off changing to AR6900-P, and what differences/ benefits would it give over AR6200? Is there anything that should be factored in for a 3 litre pertrol naturally aspirated injection engine? I currently use AR6200 in my diesel too – can AR6900-P be used in diesel cars or does it absolutely have to be AR6900-D – what's the difference?
Thanks Dan.
The best way would be to try a 100ml sample bottle and compare the two. AR6900-P delivers a better detergent package and lubricant as well as more catalyst. It may be that AR6200 works better for you on that engine. AR6900-P is NOT suitable for diesel engines. With diesel engines most customers have switched from AR6200 to AR6900-D due to the noticeable improvement from the higher cetane, detergent and lubricity.
I have a 2.2 Jaguar XF 2013 63 plate. Which is better for it, the AR6200-D or the AR6900-D fuel additive.
AR6900-D as it delivers more benefits.
My second comment; but awaiting Moderators ! I have a 2018, Nissan Qashqai 1.5, dci engine, Mileage is just 16,000 miles and it starts and runs nicely. I'm not really interested in better MPG etc… I'm more interested in keeping the engine components clean and healthy i.e. valves -egr – dpf – etc.. I'm thinking of getting Archoil AR6900-D ? do you think this is a good Idea; and what ratio of ar6900d to litres of diesel would you recommend?
Thanks Moss-
Again, AR6900-D MAX due to its detergent package and improved combustion quality. Use at 1,000:1 but can also be used at 2,000:1 with reasonable results.
sorry to ask; but is that 1,litre of 6900 D to a to a thousand litres of fuel ?
That is correct. Use 1ml of AR6900-D for every 1 litre of diesel so 1L (1000ml) of AR6900-D will treat 1000 litres of diesel.
Thank you.
Appreciate your help, I have a Litre of AR6900-D arriving today. BTW I love reading these articles; and the invaluable advice we get from reading them.
Thank you
I have a Golf GT Sport 2.0 TDi (Stage 1 chipped to ~220 bhp). Have been using an additive called 'Dipetane' on which it seems to run well. How does that differ from Archoil AR6900-D and am I likely to see any benefits (economy, performance or emissions improvements) from switching to Archoil AR6900-D??
AR6900-D will deliver more cetane and other benefits.
Thanks for the reply.
What are the "… other benefits .."??
Hi,I am soon going to change my S-type jaguar with a 2017 Jaguar XE diesel. I have always used AR 6900 D Max in the S-type and found it to be very beneficial in the car's overall running. In the XE a product called AdBlue is added to reduce emissions. Can i still use AR 6900-D max each time i refuel.?
Yes, you can still use AR6900-D.
Thank you. That's great.
What type of metal-oxide fuel borne catalyst (FBC) used on AR6900-D Max and AR6400-D Max? I've read soot on iron-oxide catalyst are difficult to burn which will result in the accumulation of PM at DPF? Could you help clarify on this please?Many thanks for the help.
Kind regards,
It uses a combination catalyst and is proprietary. The depository impact of a nano based catalyst is so small as not to pose any risk. Conventional fuel and oil based carbons will accumulate at least 100x faster than any fuel based catalyst I am aware of.
Hi I have used Millers Diesel Ecomax for some years now. I am thinking of switching to AR6900 d-max. Can you tell me
1) What extra benefits if any will i get using AR6900 d-ax?
2) What is the difference between Millers and AR6900 d-max?
I am presently using Millers in my 2014 Santa fe 2.2Thanks
A stronger detergent and the addition of a combustion catalyst that will improve combustion further.
Hi. Is it better to use AR6200 or AR6900-P MAX in a petrol engine (Honda Prelude 2.2 VTEC)?? Isn't the AR6200 a better catalyst?
AR6900-P will provide the better performance. There is more catalyst in AR6900-P.
I have Honda CR-V 2.2 diesel. Reg ML62 TYS. It has done 47.5K and I have mostly used Supermarket fuel but have been recently advised to use proprietary fuel and a fuel additive.
Is AR6900D MAX correct for my car and should I use an oil additive?-
I have a supercharged, twin plug 3.2 air cooled 911, 6 lbs boost at 9.0:1 compression, and am wanting to know if regular gas with Archoil AR6200 is a safe substitute for premium fuel?
Our premium here in Canada costs approx $1.00 more per gallon over regular..-
Not really. It will improve combustion but not provide the additional octane found in Premium.
Hi, I'm a bit confused by your comment that "AR6200 will not provide the additional octane found in Premium diesel."
But at the same time in another comment you have stated "No need to use premium diesel if using AR6200."
I have an audi A4 B9 3.0tdi, is it safe to use AR6200 with regular diesel?
Or do I need to then add AR8500 to compensate for lack of premium diesels benefits?
Or should I use AR6200 and AR8500 with premium diesel?
AR6200 was originally designed for treating bulk storage fuels, hence there is only so many functions you can deliver with a 10,000:1 ratio product. The catalyst function would help compensate in lower cetane fuels by improving combustion. However, providing a catalyst function whilst raising cetane makes an even greater difference to performance. There is no AR8500 product?
Sorry I meant AR6850.
Which combination would you recommend?
Hi there
What Kind of product Do you suggest to use on a RRS 5.0 V8 supercharged (AJ133 engine)?
I stared to use AR6200-EU and compared to pure 98RON pump gas the engine feels more responsive.
Bevor using AR6200 I ran the car on 95RON and now I noticed a black hard carboneous coat on the exhaust tips. Caused from what?-
Hybrogen or AR6900-P MAX would be the best product to use. They both improve combustion, which will lower carbon output.
I've been using Millers Diesel Ecomax and am thinking of changing to Archoil AR6200 & AR8500 or AR6900.
Should I leave a whole untreated tank before changing or is it okay just to run the tank nearly empty and then swap over?
Many thanks-
It is ok to run the tank to nearly empty. Ecomax is 2-EHN (cetane improver), lubricant and detergent so no compatibility issue.
does it make sense to mix AR 6200 and AR6900 d-max ?-
Not those two. AR6200 can be mixed with AR6850 or pure 2-EHN though.
I was using AR 6200 for long time. Now I decided to use AR 6900 D-Max. Is it nesesery to "flush" the tank by filling it up (10, 20 or 60) liters of diesel fuel wit no additives ? 10 liters will be enaugh or full tank is needed ?
No need to flush. Just use in following tank of fuel.
How can I order the diesel additive (6400D}?
Hi I am using AR6200-EU in my 3.0 TDI Audi A6, first of all it's doing what it says on the tin and I am very impressed. Secondly do I use it all the time as I am on my 3rd tank now at 5000:1 ratio so do I now use it all the time @ 10000:1 or every 2nd/3rd tank? FYI I use a good quality Diesel IE Supreme or V Power so was wondering what's the best way of using it going forward…..
Kind Regards Cole
Hi, it is designed to be used with every tank of fuel at 10,000:1. No need to use premium diesel if using AR6200.
ON PFI I can help cleaning my IVD with your PEA additive and after that with the AR6200 at each tank fill but what can do with the exhaust valves??
6% increase on a 3.0 discovery. This is more than I was expecting. I would interested in your recommendation on an oil fortifier?
Hi, for that engine I would recommend AR9100.
can you please tell me how much archoil 6900-p can i use on my petrl engine corsa
please reply soon.
Maximum 1ml for every 1L of fuel.

Okay, so I hope you like that last second we got a little deep but I think it's pretty interesting to take something that we slept through in physics class and make it applicable to data and did you ever think we'd be talking about nodes and any nodes right anyway, let's get to the fun stuff and but before I get on to this subject I just want to make make you make this very clear. I'm not a religious zealot. I'm just gonna list all the facts and dropping some opinions from time to time I know there's plenty of nasty guitar forums out there that people screaming each other over gifts Gibson versus Fender straight through next versus bolt ons but here's where I stand. All of these things that is tools in your tool belt that you use to create beautiful music and if you can do that on old Ivan as you found at a garage sale years ago, then who am I to shame you into buying you know, multi thousand dollar vintage strat if it works for you, then it's great.
It works for you. I'm just not That dogmatic to actually show you how agnostic I am on this topic. My main computer is a Mac running both Mac and Windows, I switch back and forth. I use multiple applications and multiple guitars, multiple apps, multiple stompboxes, hardware, software, whatever works and I hope you do too. I'll just try to list the options and the general positions of most of stuff out there in terms of the benefits and in the shortcomings of all options. If you don't agree about your favorite artists or about the merits of a certain guitar feature of your top, Sabir anyway after that long disclaimer, let's look at the main category of guitars.
There are many many more guitars and these four but let's just go through with the Stratocaster Telecaster, Les Paul and 335 type and in terms of what type of guitar thou art style, they are Both of the fenders and the Les Paul they're all solid. So then made out of a solid piece of wood where the 335 is a semi acoustic in terms of the woods. The fenders tend to be made out of ash and older les Paul's typically make mahogany and 325 is a maple and poplar. The scales on the fenders are 25 and a half inch the skylink and the Gibson's are 24 and three quarters coming in three quarters much shorter, which means that you need less string tension on them to bring them to the same pitch as you would anything with a 25 and a half inch scale. That's why you can get kind of more of a chunkier time out of the Les Paul my 335 because the string tension is a little bit a little bit less.
In terms of the pickups on the Stratocaster you have three single coils, two single coils and the Telecaster that there's a few things that are different on the telly. Tell is pick up as a copper plate measure on the base of the pickup and the pickup itself. under the bridge, rather than to the plastic pit guard in the case of the Stratton It's also worth noting the TELUS pickup is angled slightly towards the bridge to favor the higher overtones on its thin strings then on in terms of the Gibson's, they both have to humbuckers in terms of the invert tone strategies brought, the Telecaster is brighter than that, let's pull 10s bill bit darker and the 335 tends to be a little darker as well to sustain the fenders have good sustain the Les Paul plays the best and a 335 would probably come in a little bit less than that, but in terms of its susceptibility to feedback or whether it's microphonic.
The Stratton tele analyst poor tend not to be but the 335 tends to be a little bit more microphonic. Now because we're going to be talking about electric guitars, we need to talk about pickups. The pickup is basically a transducer that converts the movement of a string into an electrical current, if you will. Wave a wire across a magnet electric current is produced. And because the string vibrates back and forth, the resulting current is AC alternating current, the electrons move back and forth along that cable. So, a pickup is basically a magnet with a very thin, why cold around that magnet coiled around thousands of thousands of times there are several variables such as a magnet types and strengths, wide gauge and winding count which ends up making kind of how hot that pick up is and also what tonal curl coloration has, without getting into all the hairy details.
There is things that play in every part of the signal chain that color, the tone of the sound. And in AC circuits. You don't just have simple resistance you have frequency specific resistance, which means that Juda electrical characteristics, namely capacitance and inductance everyone little part of your signal path, including your cable begins to color the sound. I won't get into the math of all of that, but the capacitance of any part of the circuit will tend to be more resistant to low frequencies and inductance will be resistance resistant to high frequency and the entire path gives you a frequency curve that will just have a little resonant bump in the mids. Somewhere between say two and five k generally pickups with higher inductance will be darker in time and have higher output. Not all that decide that some pickups will sound brighter than others.
Some will have a higher output that can maybe overdrive your preamp better than others. We'll play a few guitars in a moment to hear how each guitar and each pickup sounds in your average strat. tele. Les Paul and semi acoustic. Now one other difference you'll see in guitars, whether in the pickups sorry whether the pickups are the single coils or humbuckers in a single coil will generally have a brighter sound but will be susceptible to hum the clever way that humbuckers are designed as they're wired out of phase and with reverse polarity on the magnets that way, the signal generated by inductance that is the movement of your string within the magnets that's passed through. But any noise picked up through the air, I reproduce exactly 180 degrees out of phase and they just cancel out.
Now one thing to consider is that you need to realize that your guitar is really part of a circuit we tend to visualize that signal goes down a chain into the next thing and the effects and apps speak and so on. And that's a great way visualize that signal flow. But what's really going on is that AC is moving back and forth along a circuit and things like your pickup, your cables, your load resistance at whatever you're plugging your guitar in, creates an RLC circuit. That's the inductance of the pickup, the capacitance of the cable and also how long the cable is, and what the load resistance is at the AMP or affect input the plug in, they all work together to create this low pass filter and all those variables affect how hot your signal is, and also how dark or bright The tone is.
Let's see if my four main guitars here at each of the pickup positions and hear how they sound in either a clean setting or a dirty setting. So what kind of controls are on your average guitar on your stress. Typical strat, you have a pickup selector which used to just be three ways until some guys started to realize that you can slide the selector or right in the middle to engage a combination of two adjacent pickups here. Fender has since made five way selectors pretty much the standard there, then you have the master volume control, but sometimes it just doesn't just affect the volume. I mean, it's a great way to back it off a little bit, too. Men drive your preamp into distortion, but the reduction of volume can sometimes tweak the impedance match between you your guitar and sorry, your guitar output, and that capacitance can roll off the highs if this is a real problem.
When you back this off there you can wire a treble bleed capacitor, crush your volume knob, just google treble bleed circuit for details. You then have tone controls which roll off the high frequencies. Now unless you have an active guitar, that is one that you would have to put a battery in the back something like that. The tone controls normally on most guitars are passive, which means they only cut frequencies that aren't boosting anything. So if you want to basically atone, then you would roll off the hook. high frequencies, so you're left with more fundamental than all of those shimmery harmonics.
Now, let me just put that back in a passive guitar, like any of the four we're concentrating on right here the typical time circuit is simply placing placing a capacitor, which shunts only frequencies above a certain threshold in terms of the frequency range here to ground. Generally, the smaller capacitor value the higher the frequency point will be, the larger the cap value, the lower the point will be making the tone circuit much darker when you roll off the tops in terms of where that that roll off happens in a typical strap, the tone controls after the neck and middle and with the bridge pickup, always going to stretch through that keep in mind there are many different types of strap models out there and many folks tweak their wiring so your mileage may vary. Just simply play through and experiment with those different pickup positions and see which tone controls does what on your particular guitar.
Now in your typical tele you have a master volume plus one over here, and also a master tone control which affects whatever pick up combination is selected. Now in your typical Les Paul, you'll have forgotten to bring that one out here. And also 335 you'll have a separate volume controls but each of the pickup and separate tone controls for each of them there. Now some guitars like this Epiphone, Les Paul, have special switching pots that you can pull out and turn these humbuckers into single coil. You might even have things like coil taps that tap out so we can give you less wines for a different kind of sound. There also some guitars have faced switching to now there are many different types of words that will give you different results with the main two characters.
Six would be levels of sustain and the tonal color. Now there are a bunch of different words out there that can be used for your body, top neck and fingerboard from the old standby standbys, like ashen alder used in a lot of the strat and tele bodies with maple necks but these have Maple next year and sometimes you can have a rosewood fingerboard for a slightly darker SAP. Now Woods like this will tend to give you a brighter Spanky sound as opposed to the heavier mahogany used in a lot of the les Paul's, maple and poplar is typically found on on the 335 type guitars. Now there are many exotic woods out there including some you can even use or even transport like Brazilian rosewood you can get you actually you can you can get your guitar confiscated if you travel across borders and ethnicities tree and Lacey's assorted Lacey Act now resistance to feedback.
Varies from guitar to guitar with a 335 being the most susceptible to feedback, though less than a full bodied acoustic would be. And you actually use this to your advantage by leaning your 335 towards your speaker to get a nice controlled sustained feedback. That would have to be the 335. I think interesting story. Epiphone or Gibson? Yeah, actually what happened was interesting story when I was 17 years old.
60 Or 70 years old. My dad was not a musician, took his Christmas bonus, and bought a Rhodes for my brother who was playing piano scented drums for my sister and bought me a 335 which I still have to this day. Oh, that's a cute Yes. Yeah. And so that's my 335 but that was the guitar because you know at the time All the LA studio guys were playing 335 so that's what that's what I got was a 330. Wow.
My first guitar. How only today I was 12 years old. I traded a motorcycle. For my first guitar. I have dirt bikes growing up and traded a guy for a guitar called an old style. It was a German bizarre thing had one foil pickup in the middle of it.
Six strings looked a little like a Rickenbacker 4000 series bass, kind of a sort of a really cheap version of that. That and some, I don't even remember the brand of the AMP but it had some weird design on the speaker grille and it was like it was made out of plexiglass or something the speaker grille It was a bizarre little thing. And I had a K one of the orange k fuzz pedals and that made everything just sad. Better Yeah, and that was that was my first guitar the first guitar that I bought or maybe my probably my parents bought for me was actually a Fender Telly you folks bought you can to tell yeah American Standard. Wow It was back back then in like 1989 it was on it was under $500 which was a lot of money but yeah, that was my first guitar and really the guitar I played that I cut my teeth on and I didn't get another electric guitar till after a couple years after I graduated college that I had just Telly for almost 10 years or so I convinced my parents to buy me this came from Service Merchandise.
I don't even think they're still around. It was one of those warehouse stores. You write what you want on the ticket and they bring it it comes out on the conveyor belt. But yeah, it was harmony guitar. And an AMP from service person died How old were you? Oh, that must have been a good day.
Oh, it was great. I got it for Christmas. Christmas and I immediately plug that thing in and just started banging and no idea how to tune in anything. I knew nothing about it and just want to start you know, taking taking guitar lessons and I mean the thing had action this high. You could Limbo under it. It was brutal.
It was and it was like it was so cheap. And it was you know, years later I I stripped it down and turns out was made out of plywood. It was in a solid piece of wood is a piece of plywood and just had these funky p90x pickups in it but it had this bridge it was just like a curved piece of metal with notches in it and then it had you know it was on kind of like a two nematic where it has the you know, the thumb screws that go up and down but you put all the way down to the body and the action still this high and you know, I had I known then what I don't know. I put To shim the neck and change them change the pitch but I'm not sure that the radius of the bridge either it was a it was $89 guitar and a $29 amp.
So you can see a lot of folks have many different guitars it really comes down to the style of music that they prefer now if you're in a Stevie Ray Vaughan Eric Johnson or you know john mayer, then use what they use they use strats if you're into Albert Collins or Steve Cropper or Brad Paisley then Italy would be your would be your weapon of choice if you you know, if you just can't get enough of Jimmy Page or slash or Joe Perry human, you know, you got to go with a Les Paul and Larry Carlton, Chuck Berry and BB King all took their signature sounds from semi acoustics like you know, like the 335 over here, so rather so rather than getting hung up on the exact wood and pick up combination from scratch, just counting Would my suggestion is jumped to the front of the line by looking at the guitars that most of your influences play.
So let's briefly look at the construction of these guitars and how they kind of differ. First up we have next we have basically three different types of ways in which the neck is joining the body. In your typical Gibson, you have a set neck in other words, the neck is glued to the body some set next have a tenon joint that slots down deep in the body for a more solid joint in your typical Fender, you will have a bolt on neck. And this was predicated on Leo fenders idea of mass production and ease of modification. Just pull one neck off and screw another one straight back on. It's no secret that the offender was influenced by Henry Ford and some people consider that the Telecaster was kind of like the Model T a guitar of its of its time.
Now another next now that I have an example of this, but that would be a special Right through Nick with a net goes all the way from the top here all the way to the back of the body and the rest of the body is just kind of like wings that just bolt on to the the top and the bottom of the neck right there. Now, at the end of the day, the job of these joints is to be really, really tight to transfer all the vibrations and resonance all throughout the body of the guitar. Some folks like all this subject some folks absolutely swear by step by set next but there's obviously downside is that if this neck goes bad, you got to send it back to the factory on the fender, you can just unscrew it and screw on a new one. Now, all you need to make sure of at the end of the day is that you have a very very solid joint on all those four surfaces of that of that joint bolt on that doesn't have snug plans will lose this time.
Also a set neck that used too much glue to fill the gaps will then sustain as well. Now next are typically single pieces, although some will have a detached headstocks of course, some have separate finger boards and some are just straight through next like like this. Now most next cut parallel to the ground, although some can be cut perpendicular mahogany and rosewood fingerboard that the typical combination for Gibson's maples are typically used over in fenders. Now, scale length is different here. They differ between the models 25 and three quarter inches on fenders. Gibson's are a half inch shorter coming at 24 and three quarter inches.
Now you have to tighten a longer scale to get the same pitch, which gives you a kind of a 20 year time the Gibson's have a little less string tension producing kind of a chunkier time. And course you can exaggerate this on any guitar just by tuning your guitar down a half A full step. Now in terms of pickup placement, the closer you are to the bridge, clearly, the brighter the tone will be the closer the neck, the more the fundamental you'll hear. And this has to do with the nose and the any notes that fall in different places across the neck, if you're a play an open a, the ends of the string and the nut, the nodes, they don't move, the ADDIE note is the place where most of that movement happens. And that's at the 12th fret, the exact halfway point between the nut and the bridge.
If you do a little wave theory, the wavelength of an A 110 hertz is twice the length of a string because when you think about the string has to make all of its way up and then on its way down, that's twice the length of a string. If you were to gently pull the string back at the 12th fret, you would hear a lot of the fundamental right here at the 12th fret that very few people play guitars right here. Right, plus, it doesn't really look that cool. So you play back here because of all those reflections that go up and down the string, but you know, multiple times multiples of that 110 hertz, bounced around the string at the same time. It's kind of hard to visualize because of a section of the string county bit one place at one time, but multiple harmonics all vibrate around and cancel each other out, so that you have really a constantly changing complex waveform moving along the string that represents not only the fundamental, but also those harmonics along there, too.
If you softly pull that string halfway through there, you'll hear pretty much just the fundamental, you strike the string back here. Hit the string hard, you're invoke a bunch more of those harmonics. Anyway, on most guitars, you'll have selected to Bring up more of the fundamental at the neck position or more of the high frequencies at the at the bridge position bring up this pickup here, a lot of fenders, you'll also have an angled bridge pickup to bring up the higher harmonics you can see that's close to their of the highest strings to and less comparatively of the of the low E here have a clear there are clearly good and bad places to position a pickup and I hear a lot about the magical 24th fret, you know exactly halfway through here. And there's a lot of good math to support them in terms of not wanting to place the pickup at a node of several harmonics, but there's a fatal for that reason.
And that's because all those calculations are based on open strings, the nodes shift as the string becomes shorter. And so that mystical magic magical position, the catch all that perfect node on your guitar is it's really a moving target. You fret up and down the neck. There's one more type of pickup that you might find on a guitar and that's a hex or MIDI pickup in guitar sense where you play any connected a keyboard or MIDI module you have a special pickup, that's actually six pickups in one the track the pitch of each string separately there translate that pitch into a MIDI note number that can trigger the guitar synthesizer or any other connected module. Now it's a tall order to be able to do this because a MIDI keyboard just has to have a contact underneath each key to census pitch. A guitar synth needs to track that pitch and also pitch bend as well.
As you know, when you perform by Brown, keep in mind that lower notes take longer to perform their full wave cycle and that can be enough milliseconds to introduce latency, which can kind of kill a feeling of your playing. Fortunately, this track has gotten significantly better lately with each new model that comes out. So basically translates that into something they can go out to any connected So this is a guitar that is has a specific MIDI pickup on it. There are also other ones that will just allow you to to plug in any guitar and then turn that into MIDI. And there's also some that will just do that through USB. So that's the story in terms of guitars.
Obviously, there are many more models out there to try, but it would be impossible to list them all here. It really is a monumental compliment to visionaries lightly offended that his designs have basically remained unchanged since the middle of the 20th century. That's pretty amazing. Now, a guitar is a it's a fairly simple machine, basically a fixed and resonator with electromagnetic transducers that generate small amounts of AC alternating current that move onwards to create killer time but again, if the signal chain ended right here, rock and roll would be disallowed. That's no good. Let's go ahead and look onward to the applicators. |

Wondering about how to build attachment with your baby? Mind-mindedness can help; most parents have never heard of it, but many practice it intuitively.
(Updated on February 3, 2024)
Your baby will be
ready to connect and form relationships as soon as they are born. According to the theory of attachment, each baby needs to have at least one person with whom they have a strong and mutual emotional bond.1 Many parents wonder about how to build attachment with their baby from the very early days.
The idea of attachment is important, but often misunderstood. Some books and online resources present secure attachment as physical attachment. They view attachment parenting as a set of specific practices and techniques like babywearing, bed-sharing, and breastfeeding.
Some or all of these techniques may fit beautifully into your family. But techniques do not necessarily equal attachment. Attachment is the quality of your relationship with your baby, not the techniques you use.
Attachment = relationship quality
Research shows that secure attachment forms best when parents are sensitive and mind-minded.
Sensitivity is probably not a new concept for you. Sensitive parents try to interpret their baby's signals accurately and respond promptly and warmly. They help their baby regulate emotions and provide a sense of safety: a secure base to explore the world from.
But have you heard of mind-mindedness?
Mind-mindedness is a certain way parents see even very young babies: not only as little bundles of joy and potential, but as people with minds, thoughts, and feelings of their own.2 They know that babies are tuned in right from the start. Mind-minded parents notice and consider their baby's emotions, sensations, and needs. They adjust their views and practices as they watch their baby's behaviour, instead of relying on pre-conceived notions, their own feelings and wishes, or general ideas of what babies need or should be doing.3
Mind-minded parents tend to use mind-related comments when they are with their babies. Their comments might:
That being said, not making appropriate mind-minded comments does not necessarily point to the absence of mind-mindedness: some parents don't verbally reflect but still appreciate their baby's internal states and show this through non-verbal actions.4 If you're an introvert, this might ring the bell. (Here is another reason to label actions and emotions in the moment though.)
The very first paper describing mind-mindedness was published in 1997.5 Over the following 25 years a number of studies have been completed, and collectively they show that mind-mindedness makes a difference:
Being mind-minded is naturally easier for some people than others. Some adults spontaneously characterize other people in terms of their thoughts, feelings, intentions, and motivations, whereas others focus more on physical appearance or general behavioral tendencies.13 But the good news is, mind-mindedness absolutely can be learned and practiced.14
I like to think of mind-mindedness as tuning in, seeing baby as a complete, whole person with a mind of their own, and considering baby's perspective.
You can begin practicing mind-mindedness as you prepare for your baby's arrival. Next time you are around a baby or a young child, ask yourself how they may be feeling or what they might be thinking. This is often easier to do when you don't know the child; when you do know them, their likes, dislikes, or their appearance might come to mind first:
"She is always so active";
"He is such a good eater";
"What a cute baby".
But to practice mind-mindedness, try to focus on what the child may be feeling or thinking in this moment:
"She might be overtired";
"I think he is really enjoying apple sauce";
"This baby seems fascinated by the balloons".
Once your baby is here, you can practice mind-mindedness during the daily care routines. Think about how you could do things with your baby rather than to him.
In the early days, tell your baby what you are about to do: "Let's change your diaper. I am going to carry you to the changing table".
Being talked to during care routines calms babies. In one study, newborn babies were massaged by a caregiver who made eye contact, spoke soothingly, and rocked them gently afterwards – and babies' stress hormones decreased. But when babies were massaged in silence and without eye contact, their stress hormones surged. In fact, they had stress hormone levels similar babies undergoing painful medical procedures! 15
Another way to practice mind-mindedness is simply being with your baby. Hold your baby or lie down next to her and watch her quietly. Try not to think about what you want her to do or what the charts say she is supposed to be doing at this age. Don't actively engage your baby. Try to simply see her in the moment, as she is. Notice what she is looking at, what she is working on, and what might be hard for her. Infant specialist Magda Gerber called this way of being with babies "wants nothing quality time" (wonderfully explained here by Janet Lansbury).
You will not always know what your baby needs; that would be impossible. But try putting yourself in your baby's shoes as much as you can. It will become easier as you get to now her better, and as she grows.

Cuyunon refers to an ethnic group populating the Cuyo Islands, along with northern and central Palawan. The Cuyunons hail originally from Cuyo and the surrounding Cuyo Islands, a group of islands and islets in the northern Sulu Sea, to the north east of Palawan. They are considered an elite class among the hierarchy of native Palaweños. They are part of the wider Visayan ethnolinguistic group, who constitute the largest Filipino ethnolinguistic group.
The Cuyonon jurisdictions during Pre-Hispanic times include Cuyo under the powerful Datu Magbanua, Taytay under the gracious Cabaylo Royal Family who met the remnants of Magellan's fleet who fled Mactan after Ferdinand Magellan died in battle, Paragua (Palawan) under Datu Cabangon who ruled south of Taytay and Busuanga under the peaceful Datu Macanas.
During Spanish colonization of the Philippines, Cuyo was one of the territories of Palawan that had the strongest Spanish presence, even being the capital of the entire Palawan province as one point.
Although the Cuyonon language is so closely related to Kinaray-a in Panay, very few Cuyonons actually live or speak Cuyonon in Panay, they instead settled west to the island of Palawan where the ethnic group is so closely associated now, this being the Province of Palawan declared Cuyonon as its official language. The fact also remains that most of the other ethnic groups of Palawan can fluently speak this language because Cuyonon had been the lingua franca of the Province of Palawan for many centuries already.

Revolutionize Family Bonds: Unleash the Power of Social Media Accountability for Phenomenal Connection
Revolutionize Family Bonds: Unleash the Power of Social Media Accountability for Phenomenal Connection
In today's fast-paced digital age, social media has become an integral part of our lives, revolutionizing the way we connect and communicate with others. While it has its fair share of criticisms, social media also offers immense potential to strengthen family bonds and foster a sense of accountability among its users. By leveraging the power of social media accountability, families can create a supportive and connected environment, leading to phenomenal connections that transcend physical boundaries. In this article, we will explore the history, significance, current state, and potential future developments of social media accountability in revolutionizing family bonds.
The History of Social Media Accountability
Social media platforms have come a long way since the early days of their inception. The concept of social media accountability, however, emerged more recently as individuals began to recognize the impact of their online actions on their offline relationships. The rise of cyberbullying, online harassment, and the negative consequences of unchecked behavior prompted the need for a system of accountability within the digital realm.
The Significance of Social Media Accountability for Family Bonds
The significance of social media accountability for family bonds cannot be overstated. By promoting responsible and respectful behavior online, families can create a safe and supportive environment for all members. Social media accountability encourages open communication, empathy, and understanding, fostering stronger bonds among family members. It also allows families to share their values, traditions, and milestones with a wider audience, creating a sense of pride and connection.
The Current State of Social Media Accountability
Currently, social media platforms are taking steps to address the issue of accountability. Many platforms have implemented reporting systems, content moderation, and community guidelines to ensure a safer online environment. However, the responsibility of promoting accountability lies not only with the platforms but also with individual users and families themselves. It is crucial for families to actively engage in discussions about responsible social media use and set clear boundaries to maintain a healthy balance between the virtual and real world.
Potential Future Developments of Social Media Accountability
As technology continues to evolve, so does the potential for social media accountability. Artificial intelligence and machine learning algorithms are being developed to detect and prevent harmful behavior online. In the future, we can expect more sophisticated tools that empower families to monitor and manage their online presence effectively. Additionally, the integration of virtual reality and augmented reality into social media platforms may provide new avenues for families to connect and engage with each other in immersive and meaningful ways.
Examples of Promoting Family Accountability on Social Media
- Creating a Family Social Media Policy: Establishing a set of guidelines and expectations for social media use within the family can promote accountability and responsible behavior online. This policy can include rules regarding privacy, appropriate content, and respectful interactions.
- Regular Family Discussions: Engaging in open and honest discussions about social media use can help family members understand the potential consequences of their actions and the importance of accountability. These discussions can also serve as an opportunity to address any concerns or challenges that arise.
- Monitoring Online Activity: Parents can monitor their children's online activity to ensure they are engaging in positive and safe interactions. This can be done through parental control software or by actively participating in their online lives.
- Encouraging Positive Online Behavior: Families can actively promote positive online behavior by sharing uplifting and inspiring content, engaging in meaningful conversations, and supporting each other's online endeavors.
- Leading by Example: Parents and older family members can lead by example by demonstrating responsible and respectful behavior online. This sets a positive precedent for younger family members and reinforces the importance of social media accountability.
Statistics about Social Media Accountability
- According to a survey conducted in 2020, 78% of parents believe it is important to monitor their children's social media activity to ensure their safety and promote accountability.
- A study conducted in 2019 found that 62% of teenagers believe that social media platforms should do more to prevent cyberbullying and hold users accountable for their actions.
- In 2021, it was reported that 45% of adults have taken steps to limit their social media usage to maintain a healthy balance between their online and offline lives.
- Research indicates that individuals who feel a sense of accountability on social media are more likely to engage in positive interactions and contribute to a supportive online community.
- A study conducted in 2018 revealed that 85% of social media users feel more connected to their family members when they engage with them on social media platforms.
Tips from Personal Experience
- Set Clear Boundaries: Establish clear boundaries regarding social media usage within your family. This includes guidelines on screen time, privacy settings, and appropriate content.
- Educate Yourself: Stay informed about the latest social media trends, features, and potential risks. This knowledge will empower you to guide your family members effectively and address any concerns that may arise.
- Encourage Open Communication: Foster an environment of open communication where family members feel comfortable discussing their online experiences, challenges, and concerns.
- Lead by Example: Be a positive role model by demonstrating responsible and respectful behavior on social media. Your actions will influence the behavior of your family members.

SOUNDBOARD: Italian Spruce

VARNISH: Shellac
The brothers Vincenzo and Nicola De Bonis carried on the historic family lutherie tradition of Bisignano (Cosenza) until a few years ago. Nicola has also built stringed instruments, which are very rare, but the guitar is the instrument in which he effectively expresses his understanding of the work of an excellent luthier. In this guitar of his, an instrument of great charm, with a complete and balanced sound, perfectly preserved today, we find all his qualitative characteristics as a craftsman-artist.
To build and finish a good violin, the De Bonis take no less than five months, time also necessary for a satisfactory drying of the glue and varnish. In their opinion, one of the most delicate operations is that of cutting the f-holes on the lid of an instrument. So much so that Niccolò Amati (1595-1684), precisely by increasing its shape compared to the previous models, gave more sweetness to the voice of his violins. Furthermore, the choice of wood is very important, the fibrous compactness of which must be considered and, even more, the seasoning, the age of the maple, for example, is around ten to fifteen years, never less.
The application of the glues and the varnishing are particularly accurate. Without the latter, the sound of a violin is altered fifteen to twenty years after its birth, losing purity.
The existence of the violin, however, has many unknowns, some of which, among the small and little known, are attributed to two pieces of pine wood glued inside the instrument: a tiny rod (the "chain") , about thirty centimeters long, placed on the inside of the lid, and a
smaller cylinder (the "soul"), six to seven millimeters in diameter, placed between the lid and the bottom. These not very visible elements, in addition to their mechanical function, have such an intimate influence on the sound performance, that they even troubled Antonio Stradivari (1643-1737) in determining their quality, aging, shape, dimensions, position.
The fact is that an excellent violin is born from a whole fusion of complicated adaptations, elusive tricks, whose formula escapes pure and simple technology, because it is also created with intuition, with the genius of the luthier. In this regard, it is said that Andrea Amati (1500) wandered in the Tyrolean forest in search of middle-aged pines, beating their trunks with wooden mallets in order to listen to their internal vibrations, those vibrations that he would later manage to perpetuate in the bottoms of his instruments. It is also said that he obtained maple lids from oars of ancient galleys lost by the Turks.
In short, the fact is that no manual has ever been able to present the key to the secret combination in detail, no luthier has ever been able to perfect the voice of the violins more than the Amatis, the Stradivaris and the Guarnieris.
Bisignano, a populous agricultural center overlooking the Crati valley from the top of a spur, is famous in the region for its handicraft activity, which in the past thrived mainly with displays of sacred sculpture (pulpits, choir stalls, lecterns, wooden altars).
The wood carvers were gradually replaced by numerous clay workers and, in particular, by the potters, today large-scale producers.
But the current fame of the craftsmanship derives above all from violin making, from a centuries-old workshop of luthiers, in which the same family, the De Bonis family, works from generation to generation. "In the Italienische Geigenbauer, Ghota's almanac of luthiers - writes Giuseppe Grazzini in Epoca (February 12, 1961) - the De Bonis are spoken of as a dynasty. There is a Francesco I, a Francesco II, a third, a fourth, like the Giacintos, the Micheles, the Nicolas, the Vincenzos, the Rosarios, variously alternating like the branches of an imperial family tree.These are centuries of history, the history of a secret and unexpected Calabria, that of music. The story of a workshop where with the same chisels, the same shapes, the same woods, above all with the same love, someone repeats the miracle of creating a living instrument every day.Violins, guitars, mandolins, ukuleles, everything is born in this workshop in identical models for centuries.The grandchildren become fathers, then grandparents, then they leave seeing that the last born are already ready to take the place left empty, to continue that work that must never end.
In the De Bonis workshop we come across the image of Giuseppe Verdi as that of an important friend who went to Rome for a few days. The sense of time no longer exists. It could really happen that the door opens and Verdi enters to ask for a violin. It happened once before, after all. As has happened for many other musicians. It was always the same shop, it was always a De Bonis who said yes, who would have done his best to please that illustrious customer. With the same modesty, a virtue so rare, yesterday as today".
In the De Bonis workshop the specialties are violins and harp mandolins, concert guitars and swing guitars.
The laboratory, for those who visit it, looks like a tangle of wood, bones, varnishes, glues, tools, colours. But for the De Bonis family everything is in its right place, nothing is out of order; they know how to find with their eyes closed the spruce for the soundboards, the ebony for the keyboards, the veined and moreed maple or the rosewood for the soundboards or for the necks, the ribs and the ox bones for the purfling or for the inlays or for the mouths. It is an orderly disorder, as artists know how to see and want.
And this, perhaps, has not happened for any other product of man, both of his art and of his science.
A luthier can make use of quite a few scientific, technical and aesthetic rules for the construction of a violin, and by following these alone he can produce just one commercial instrument. But to create a valuable model he needs instinct, talent, imagination, experience, and these prerogatives are not foreseen by any treaty.
Experience, evidently, is the last secret in the hierarchical succession of qualities necessary for those who make musical instruments, but it is, in all probability, the absolute first in terms of degree of importance. And this secret, for the De Bonis. it is inheritable by their children's children, and that's it, as an inextinguishable, perpetual spiritual legacy. Thus commanded the fathers of their fathers for ever, and that command is inviolable. It's law. A law that miraculously continues to survive the pressures of contemporary pragmatism: the moral law. |

More and more terminal companies are using TFT displays as display devices for terminal products as interconnection technology advances. Do you know how to transport and store a TFT LCD display after purchasing one?
When the TFT display leaves the factory, qualified manufacturers will conduct vibration tests, however they should endeavor to minimize strong vibrations during delivery or installation.
Our TFT LCD panel is an LCD item that is liquid, not solid. In general, problems could exist if the liquid crystal arrangement is damaged during vibration. You can try to manage it carefully as a result. Use the original packing if you need to transport it.
Never introduce moisture to the TFT display. When the humidity is too high, condensation may form inside the TFT display, which can easily result in leakage, short circuiting, and in severe situations, even burning of the TFT display.
The TFT display screen can now be placed in a warm, dry location to prevent the TFT liquid crystal display screen from becoming wet and losing its ability to display properly.
The TFT LCD screen should ideally be installed on the machine after passing the inspection because all parts have an expiration date and if it is stored for an excessively long period of time, the TFT display screen will appear odd.
Such as aging, backlight fading, and even display incapability. In order to prevent missing the ideal installation chance, strive to finish the LCD screen installation within 3 months.
Pins used for connection: A TFT parallel screen requires several wires to connect, whereas a TFT serial screen simply needs two wires to function.
Programmable: The majority of commercially available serial ports are intelligent, include configurable features, and are incredibly easy to use. In comparison, the parallel port screen uses 90% less power than the serial port screen, and even many TFT LCD serial port screens may be controlled without a microcontroller. If the parallel port is utilized, the software is highly complex.
Interface: Special software is used for the serial screen's interface. Interface for immediate download is straightforward.
Although the performance of the single-chip microcomputer system is not particularly good, it uses the protocol to control the content of the liquid crystal display. Since the operation of menu, text, dynamic curve, and picture can be realized only by writing the serial communication program of TFT LCD screen, the requirements for R&D personnel are low, and the development cycle is much faster, it can be said that it is a recommended choice for those who are eager to produce products quickly or for beginners; general 8-bit computers can even easily control true color 10.4-inch and 8.4-inch LCDs;
It is easier to edit the general software or correct it to finish the update process if the LCD terminal has a serial port; this is because serial port drivers have excellent anti-interference capabilities and typically work well in power and cars.
In general, it is now a small board that can be incorporated in the system of the user, and the video memory can be operated directly and operates at a quicker rate than the serial port of the TFT LCD screen.
Simple function and little cost.

Contech's story began in the 1950s, when the Government called for tenders for the Roxburgh Dam.
That contract was won by an international joint venture that included Conrad Zschokke, a contractor from Switzerland.
Once the project was complete Zschokke established a local presence, joining a Masterton company to form Rigg Zschokke. When in the early 1960s projects started requiring post-tensioning technology, Zschokke's Swiss-based business associate BBR was in the perfect position to help. In 1963 BBR New Zealand was born. Adding to the story was a young engineering graduate called Rob Irwin, who had travelled to Europe in 1961 and secured a job with Conrad Zschokke. Antonio Brandestini, who also worked for Conrad Zschokke, was one of BBR New Zealand's founders.
Rob went on to gain post-tensioning experience in Switzerland, then in 1966 returned with his skills and experience to take over the running of the team at BBR New Zealand. This was the start of BBR Contech. Since 1963, a series of mergers and acquisitions has seen the company change names, market new skills and techniques and undertake a diverse range of projects in New Zealand and overseas. Throughout, its core capabilities have remained a constant: harnessing BBR's world-leading post-tensioning technology and partnering with other global technology specialists to complete ground anchoring, construction engineering and structural maintenance, repair and retrofitting projects.
Today, the company is known as Contech, with headquarters in Auckland, offices in Wellington and Christchurch, and a dedicated team of some 70 concrete engineering specialists working with clients nationwide. It's widely recognised for its outstanding technical expertise and is an active member of the BBR Network, working in close collaboration with other members around the world.

At some point you will transition from your prime earning and saving years to that time where you will need to "live off your acorns." These will be the years when you will be drawing from your accumulated nest egg. Before you enter this phase, you'll need to find the best retirement investments; ones that generate regular cash flow. For most people, the best retirement income plan uses a strategically selected combination of the following investment types.
1) Immediate Annuities
Immediate annuities provide guaranteed income immediately (hence the name). They are a form of insurance rather than an investment (but still included here because they provide steady cash flow). A ten-year term-certain annuity, for example, buys a stream of income for ten years. Because immediate annuities start paying out right away, they appeal to people already retired. They are not for everyone – they tie up assets, and you may "lose" money if you die before fully "cashing out." Immediate annuities may be advantageous if you have trouble staying within your spending limits, cannot stick to an investment plan, or have no monthly sources of income besides Social Security.
2) Bonds
Bonds, individual or bundled-in funds, are loans you give to governments, municipalities, or corporations that then pay you regular interest. When the bond matures, its face value is returned to you. A time-segmented or asset-liability matching investment strategy will use bonds in a bond ladder, which is a collection of bonds that have different maturity dates set to match your future cash flow needs. Bonds are a lower-risk option than stocks, but during periods of rising interest rates, bonds go down in value. If you are holding the individual bonds to maturity, this decrease has little impact on you, but if you are in a bond fund, the share price will drop, and you may lose money if you sell it during that time. We prefer using individual bonds in our retirement income portfolios. Buy bonds not to grow money but for the regular interest income they produce, and for the structured principal amounts you receive when they mature.
3) Retirement Income Funds
Retirement income funds are great for folks who aren't interested in keeping regular tabs on their portfolio. They are a type of mutual fund which automatically invests your money in a diversified portfolio of stocks and bonds. The fund's goal is to produce monthly income. Most people have experience with mutual funds, so they feel comfortable with retirement income funds. And, like mutual funds, retirement income funds are set up so you can access your money at any time. You may see these funds listed with a name like "Target Date 2040" which means the fund is structuring the investments to align with someone who wants to retire in about 2040. Other funds will have the words "retirement income" in their name such as Vanguard's Target Retirement Income Fund, geared towards those already in retirement.
4) Rental Real Estate
Renting out property for income requires a hands-on approach and, in many cases, more work than you may desire during your golden years. Research and forethought are key. Before you decide to become a landlord in retirement, consider the rental property expenses you may incur over the time frame you plan to own the property, like maintenance, damage from negligent renters, natural disasters, etc. You also need to factor in vacancy rates—no property remains rented 100 percent of the time. For those with a real estate background, or if you want to put the time in, real estate can be a great source of regular income, but go in with your eyes wide open.
5) Real Estate Investment Trusts (REITs)
A REIT (Real Estate Investment Trust) is a mutual fund that aggregates real estate holdings (apartment buildings, commercial structures, vacation properties, etc.). For a fee, professionals manage the properties, collect rent, and pay expenses, and you receive the remaining income. As part of a diversified portfolio, REITs can be a good retirement investment choice.
6) Variable Annuity With a Lifetime Income Rider
I devote twelve pages in my book Control Your Retirement Destiny to variable annuities. That's because they're complicated. In a variable annuity, your money goes into a portfolio of investments you choose. For a fee, you can add an optional benefit called a rider. The rider insures the amount of future income you can withdraw from your portfolio. Variable annuities come in many flavors, and many people who offer them don't truly understand them. Be cautious – sometimes, I see variable annuities with total fees running about three to four percent a year. Your investments will have to earn back the fees and more for you to benefit.
7) Closed-End Funds
Not for newbie investors, closed-end funds encompass a wide range of investment approaches that may be unfamiliar to the layman (they overlay stocks and bonds with strategies like dividend captures and covered calls). Income comes from interest, dividends, premiums from selling options like covered calls, or return of principal. Some closed-end funds use leverage (they borrow against the portfolio) —an additional risk that is employed to buy more income-producing securities so the fund can pay an overall higher yield. Closed-end funds can be a great retirement investment option, as part of a mix, for savvy investors.
8) Dividend Income Funds
A dividend income fund, like other funds, is a collection of stocks overseen by a fund manager. The dividends you receive come from the dividends paid out by the underlying stocks in the fund. Dividends can rise one year and fall the next. Some publicly-traded companies generate qualified dividends, which are taxed at a lower rate than other income. As such, it may be most tax-efficient to hold qualified dividends within non-retirement accounts (meaning not inside of an IRA, Roth IRA, 401(k), etc.). I caution clients to be wary of funds that advertise high yields – yields that are higher than average typically come with additional risks.
9) Total Return Portfolio
When done right, a total return portfolio is one of the best retirement investments out there. It is not a stand-alone investment; it is a strategy that uses a balanced, diverse blend of stock and bond index funds that provide retirement income in the form of interest, dividends, and capital gains. The portfolio is designed to achieve a respectable long-term rate of return, and along the way, you follow a prescribed set of withdrawal rate rules that will typically allow you to take out 4-7 percent a year and, in some years, increase your withdrawal for inflation. What does "total return" mean? Well, unlike a Certificate of Deposit, which has a specific interest rate, with a total return portfolio, you don't know what the actual return will be each year. Some years, your investments could be up 14%, and other years, down -14%. But over a ten-year span of time an appropriately structured mix of investments, such as 60% stock index funds and 40% bonds, has a high probability of earning a 6-7% average rate of return. So you are targeting that "total" average return rather than knowing the exact outcome each year.

Keep in mind many of the choices discussed above are investment products, not financial planning tools. Many financial advisors are salespeople who place too much emphasis on investment selection and investment products and too little on planning. Make sure you have a well-designed retirement income plan in place before you buy any financial product. |
BEST around: PLAS Robotics team readying for competition
Published 4:00 am Thursday, September 10, 2015
The Pike Liberal Arts Robotics Team is gearing up for the BEST (Boosting, Engineering, Science and Technology) robotics competition coming up this Halloween. This is their second year to compete.
"We get no instructions," said Alissa Jordan, the robotics class teacher and sponsor for the team. "We get a set of materials and a goal."
On Sept. 19, the two classes that make up the Robotics Team will receive a "truck-load" of materials to create a robot with a list of limits that must not be exceeded. The team will have 40 days to complete the robot. The catch is that they do not know what the robot will have to do once on the competition field.
The task at hand sounds pretty challenging for students who are taking an introductory robotics class. To help with the process, engineers from Sikorsky come to teach the students and work with them, guiding them in the processes.
"These gentlemen are donating their time and energy and expertise to help us build and compete in the BEST robotics competition on Halloween," Jordan said. "The engineers are teaching them the engineering process, but it's hands-on. It's great because the students are learning from somebody who does that for their job."
The engineers act as "mentors" during the 40-day journey to build the robot. They do not build anything for the students or do any of their work; the mentors simply guide them in the right direction.
Although the Robotics Team is not technically a sports team, Jordan said other students from the school come to watch and cheer on the team.
"It's insanely crazy," Jordan said. "Everybody is cheering them on, but the students are totally focused because they only have three minutes to complete the task."
The engineers go to the competition with the students, as well. Jordan said they go on the field with them and act as their "pit crew."
Jordan said that being able to have engineers come into the classroom is one of the best ways for the students to learn.
"It is one of those things where it is the community and the schools partnering," Jordan said. "It's the most valuable way to learn. It's huge to have the community team up with the schools."
The robotics class is an "invaluable" asset, according to Jordan. The value doesn't stay within the walls of the classroom; it will follow them to college.
"How many students are going to go to college and go into an engineering class and say they have already worked with those software and tools?" Jordan said. "They are already leaps ahead."
She said that value would follow them into the career field.
"Companies are going to look at them first," Jordan said. "They already have a good foundation. They are ready to be employable."
The BEST Robotics Competition will be Oct. 31 at the Ozark Civic Center from 10 a.m. to 4 p.m. |

Science, Bitches! | Issue 14
Get Amongst the Green
Snow in autumn? Huh, where's that global warming when you need it, amirite?! Bit of a misnomer really, because what we are facing is climate change – exactly the sort of thing that causes snow at weird times. As well as that crazy ass storm over the break. And, you know, Australian weather.
The debate about whether it is happening is over – 97 per cent of scientific papers agree climate change is a thing. The question now is: what are we going to do about it?
I could talk biofuels and electric cars, but solar-powered planes are way cooler! Well, one in particular. HB-SIA is entirely solar powered, and travelled 15,000km nonstop – about the length of NZ. Remember that joke about the Irishman and the solar-powered torch? Yeah, not so funny now – the plane had enough energy from the sun to keep going all night long. Rad. Their next mission is to fly around the world!
Okay, so maybe building a solar-powered plane would be a bit tricky to do between classes, but what about a phone charger? Yep, it looks pretty doable too – you do need to get hold of stuff like a soldering iron, but all up parts only cost about $30! Basically, hook up a couple of mini solar panels to AA batteries and connect that to a USB port. Plug your phone in and you're good to go! There are some pretty detailed instructions online, although the practicality of solar power in Dunedin is questionable …
Don't know anyone with a soldering iron? There are endless other ways to be green. Need some inspiration? Wellington Zoo has just become the world's first certified carbon neutral zoo! Now, before you run off to tell all your friends this incredibly exciting news, consider this: this is a zoo, in Wellington, which has tropical animals that like to be warm. There are animals with very specific diets. There is a fully functional animal hospital, and a separate heated "sick room" big enough for a giraffe.
Now I understand not everyone has a back yard big enough for a closed-loop compost/vege garden system and rainwater tanks. "Gosh Elsie, can't you think of any easier things, like switching off lights and shit?" Well do that too, but why not get amongst Generation Zero? They're a bunch of pretty great people that are all about making NZ a better place for everyone. If you sign up they'll keep you up-to-date with all the things they're doing, and how you can help. There's even a sweet speaking tour about to start, and yes, it is free. They're coming to do a talk here next Monday (15 July) – sign up and get yourself educated! Because, you know, one day we'll run out of liquid dinosaur so we might as well be ahead of the game.
Or we could all just become photosynthetic, like the Elysia cholorotics. It's a sea slug that steals chloroplasts from algae and stores them in its skin cells! Chloroplasts are the mini-organs inside plant and algae cells that use the sun's rays to make energy from water, which is cool enough on its own. And on top of that, the slug is pretty much a fusion of plant and animal. That's two branches of evolution touching, just the tips. Instead of eating, it just sunbathes all day, sweet lifestyle! Considering we can now print organs in 3D (another story for another day) the possibilities are kind of endless. Just imagine, an extra layer of skin and you'd never have to pay food bills again. Going green could get more literal one day. That's science, bitches! |

Cardamom is a versatile and aromatic spice that is treasured in culinary traditions around the world.
You will find cardamom pods at the heart of many spice blends, lending their distinct warmth and sweetness to dishes from savory curries to spiced teas.
With its complex aroma, cardamom pairs exceptionally well with a variety of ingredients, elevating recipes with its rich and eucalyptus-like essence.
The pods themselves are a marvel of nature's palette, encapsulating the diversity of flavors within a range of colors.
Typically, you'll encounter green cardamom pods, which are the most common variant found in grocery stores and spice markets.
These green pods are known for their bright flavor and are a staple in both sweet and savory cooking.
On the other hand, there exist white cardamom pods, which are essentially green pods that have been bleached to a milder taste, and black cardamom, which boasts a more smoky and robust flavor profile.
Botanical Overview
In this section, you'll explore the rich tapestry of cardamom, from its diverse species to how it's cultivated and the role it plays in global trade and culture.
Species and Varieties
Cardamom belongs to the Zingiberaceae family, commonly known as the ginger family.
Green cardamom (Elettaria cardamomum) and black cardamom (Amomum spp.) are the main varieties.
Green cardamom is native to India, while black cardamom, which is larger and has a more smoky flavor, originates from the eastern Himalayas. White cardamom is merely green cardamom that has been bleached for aesthetic purposes.
The Plant and Growth Conditions
The cardamom plant thrives in tropical climates with consistent moisture and shade.
India and Guatemala lead in its cultivation, with significant contributions from Sri Lanka and Nepal.
Cardamom plants prefer altitudes ranging from 600 to 1500 meters, and typically grow in forests or on plantations with large trees providing necessary shade.
Harvesting and Post-Harvest Processing
Harvesting of cardamom pods is delicate work, usually done by hand to maintain the pods' integrity and freshness.
After harvest, the pods undergo drying, a critical step that determines the quality of the spice.
The drying process must cater to the particular variety; for example, green cardamom is dried quickly to retain its color and volatile oils.

Nowadays, Chinese cities have entered the stage of cultural bathroom enjoyment. In the research and development of products, it is important to take into account human behavioral factors. A certain bathroom brand once organized a consumer survey, and one of the questions was "What kind of bathroom do you need?" Among the answers received, there are four types of answers (Z concentration): firstly, the decoration of the bathroom is simple and comfortable, but it can also reflect a person's identity and status; The second is to have high requirements for bathroom decorations and furniture; The third is functional sanitary ware; The fourth is the large space, ranging from 4 square meters to 10 square meters, with good lighting. The second question of the survey is "What are the requirements for the selection of bathroom decoration?" 80% of the respondents answered, "I hope it is matched and has a consistent style. Z is good enough to use a brand." These are the basic data for building bathroom spaces.
Home Beauty Salon
As long as your economic strength permits, you can move the equipment of SPA beauty salons and hospitals into the bathroom as much as possible, trying to make every detail in the bathroom a health prop: comfortable massage bathtubs, saunas, and light wave bathrooms are no longer luxury goods; Advanced nanotechnology endows ceramics with antibacterial properties; Even the toilet has become an advanced instrument for examining the body. What other reason do we have to refuse to have a comfortable SPA or a full body health check in the bathroom at home?
Water saving everywhere
There is an induction faucet that signals "water conservation". When the hand reaches the water, it will come out, and when the hand moves, it will stop. Cancel the water consumption period when turning off the faucet; There is also a constant temperature faucet, which pre adjusts the water temperature before leaving the factory, so that when the faucet is gently turned on, it immediately releases water at a pleasant water temperature and appropriate flow rate, controlling waste to a low limit from the beginning. The structure of its faucet is very precise, which can automatically and continuously compensate for changes in water pressure and temperature, making the water temperature instantly reach the user's temperature requirements, and controlling the temperature difference within 0.5 ℃, thereby further reducing water waste.
As for water-saving toilets, in response to everyone's trust in direct flushing water-saving, the siphon style boldly innovates and introduces a jet siphon style that is both silent and water-saving. Some manufacturers are not satisfied with the 3/6-liter water flow switch and have launched 4-liter water-saving sanitary ware, which has received very good feedback from consumers. There are even waterless urinals, which is simply saving water to zero.
Intelligent technology
From smart seats to smart bathtubs, the deep development of smart bathroom products allows us to clearly see that products with new concepts will continue to lead the trend of the bathroom market. The faucet equipped with an infrared sensing device has the function of automatic water discharge and soap dispensing; The voice controlled shower nozzle can adjust the water temperature or spray amount according to verbal instructions; The toilet has many functions such as warm water flushing, warm air drying, seat heating, automatic anti fouling and deodorization, etc
Infrared sensing technology is widely used in water discharge control and water-saving control. A bathtub or toilet with infrared sensing water outlet control function can adjust the time interval of the massage outlet or toilet outlet according to preferences, and grasp the rhythm and intensity of the water flow.
Alien design
Bathroom is the part of a house that reflects quality. This year, fully transparent bathtubs and basins have emerged in various shapes, including semi-circular, triangular, pentagonal, petal shaped, or 1/4 circular. The bathroom is no longer just white and bone colored, but full of colorful colors.
Magical concealment
Have you ever seen water flow from the ceiling into a bathtub? Have you ever seen a faucet hidden in a wall? Have you ever seen a toilet that can't see the water tank? In fact, there can be many unexpected changes in bathing spaces, and nowadays, concealed sanitary ware has become a popular choice among many consumers.
The wall mounted faucet can be hidden on the ceiling or the side wall of the bathtub, consisting of a spout and a drip tray. Those who are not familiar with it may think it is an exquisite decoration embedded on the wall above the bathtub. With a light touch of the switch, water miraculously gushes out of the wall, and the water column is crystal clear and full. If this type of faucet is installed on the ceiling of the bathroom, the water column can also shoot into the bathtub like rain from the ceiling. The concealed water tank and hanging toilet can provide the bathroom with Z best space utilization, making it more concise and spacious.

In the vibrant economic landscape of Denver, where innovation meets tradition, businesses are constantly navigating the challenges of growth and financial management. Amidst this dynamic backdrop, the role of financial management services, particularly bookkeeping and CFO services, has never been more critical. Bookkeeping Solutions 5280 stands at the forefront of this evolution, offering a suite of virtual bookkeeping services designed to meet the unique needs of Denver-area businesses. However, the journey towards achieving comprehensive financial health and strategic insight does not end with traditional bookkeeping. This is where the concept of a Fractional CFO comes into play, bridging the gap between day-to-day financial record-keeping and high-level financial strategy.
The Role of Traditional Bookkeeping
At its core, traditional bookkeeping involves the systematic recording, organizing, and maintaining of a company's financial transactions. This foundational financial task is indispensable for several reasons:
Ensuring Accuracy and Compliance
Accurate bookkeeping is crucial for maintaining compliance with tax laws and regulations. It provides a clear, factual account of a business's financial history, which is essential for tax reporting and preparation. In a bustling economic hub like Denver, where businesses face both opportunities and challenges, staying compliant is non-negotiable.
Facilitating Financial Management
Bookkeeping serves as the backbone of a company's financial health. By keeping meticulous records of income and expenditures, businesses can better manage their cash flow, making informed decisions about investments, expenses, and savings. In a competitive market, such financial discipline can be the difference between thriving and merely surviving.
Limitations in Strategic Planning
However, traditional bookkeeping, for all its virtues, has its limitations. While it excels at keeping an accurate ledger of financial transactions, it does not inherently provide the strategic insight businesses often need to navigate complex markets or make pivotal financial decisions. Bookkeeping records what has happened financially, but it does not forecast, analyze, or strategize based on that data. As businesses in the Denver area grow and the economic landscape becomes more complex, the need for deeper financial insight becomes paramount. This insight is crucial not just for surviving but for thriving, necessitating a move beyond traditional bookkeeping practices.
The transition from merely recording financial transactions to interpreting them and making strategic decisions based on that data marks a critical evolution in a business's financial management journey. This is the juncture at which the expertise of a Fractional CFO becomes invaluable. Through a combination of traditional bookkeeping excellence and strategic financial guidance, Bookkeeping Solutions 5280 is poised to help Denver-area businesses not just navigate but excel in their financial management practices.
The Emergence of Fractional CFO Services
As the business landscape becomes increasingly complex and competitive, especially in vibrant markets like Denver, the need for high-level financial guidance has grown exponentially. This need has given rise to the concept of the Fractional CFO, a strategic evolution in financial management services that addresses the limitations of traditional bookkeeping.
Definition of a Fractional CFO and the Concept Behind Fractional Services
A Fractional Chief Financial Officer (CFO) provides high-level financial strategy, planning, and analysis for businesses on a part-time or contract basis. Unlike a full-time CFO, a fractional CFO offers their services to multiple companies, typically smaller businesses that do not require or cannot afford a full-time executive in this role. This arrangement allows businesses to benefit from expert financial guidance without the overhead associated with a full-time position.
The Gap Between Bookkeeping and CFO-Level Strategy That Fractional CFOs Fill
Traditional bookkeeping tracks and organizes financial data, which is essential for operational success and compliance. However, it stops short of interpreting this data to forecast future trends, make strategic decisions, or guide the company toward financial optimization and growth. This is where Fractional CFOs step in, leveraging the data organized by bookkeeping to provide strategic insights that drive business success.
Benefits of Fractional CFO Services for Small and Medium-Sized Businesses
For small and medium-sized enterprises (SMEs) in the Denver area, the advantages of engaging a Fractional CFO can be game-changing. These benefits include:
- Access to Expertise: SMEs gain access to the same level of financial expertise as larger corporations without the full-time expense.
- Strategic Financial Planning: Fractional CFOs help businesses plan their financial future more effectively, identifying opportunities for growth and expansion.
- Cost Efficiency: By employing a Fractional CFO, businesses can optimize their spending and investment, ensuring resources are allocated in the most efficient way possible.
Strategic Financial Guidance: Beyond the Books
Fractional CFOs offer much more than traditional financial management; they provide strategic financial guidance that can steer a company toward long-term success. Key areas of focus include:
Financial Forecasting and Budgeting
Creating detailed financial forecasts and budgets is crucial for strategic planning, enabling businesses to set realistic goals and measure their progress accurately.
Cash Flow Management and Optimization
Effective cash flow management ensures that a business can meet its obligations on time, avoid excessive debt, and invest in growth opportunities. A Fractional CFO can identify strategies to improve cash flow, such as renegotiating terms with vendors or optimizing inventory levels.
Risk Management and Mitigation Strategies
Identifying and mitigating financial risks, from market fluctuations to regulatory changes, is crucial for maintaining business stability. Fractional CFOs can help businesses develop strategies to minimize these risks.
Strategic Planning and Financial Decision Support
With their broad view of the company's financial health, Fractional CFOs play a key role in strategic planning, helping to guide major business decisions and investments.
Fundraising and Investment Strategies
For businesses looking to raise capital or invest in new ventures, a Fractional CFO can provide invaluable guidance, from choosing the right funding sources to evaluating potential returns on investment.
The Role of Technology and Data in Enhancing Strategic Financial Guidance
In today's data-driven world, leveraging technology to enhance financial analysis and decision-making is critical. Fractional CFOs often bring advanced tools and technologies to bear, providing deeper insights and more accurate forecasting.
By bridging the gap between basic bookkeeping and strategic financial management, Fractional CFOs enable Denver businesses to navigate their financial futures with confidence and precision. In a competitive and ever-changing business environment, the strategic guidance provided by a Fractional CFO is not just an advantage; it's a necessity.

These success stories underscore the transformative potential of combining day-to-day financial management with strategic planning and analysis, demonstrating how Denver businesses can leverage Bookkeeping Solutions 5280's expertise to achieve their financial goals.
When to Consider a Fractional CFO for Your Business
Recognizing the right time to engage a Fractional CFO can be a pivotal decision for a business. Key indicators include:
- Growth Phases: If your business is entering a growth phase and requires sophisticated financial strategies to manage this growth effectively.
- Financial Complexity: When your financial management needs become too complex for basic bookkeeping to handle adequately.
- Strategic Decisions: If your business is facing significant strategic decisions that require in-depth financial analysis and guidance.
- Resource Optimization: When you need to optimize your financial resources but lack the in-house expertise to do so effectively.
The Importance of Timing and Scalability
Engaging a Fractional CFO at the right time is crucial. Too early, and you may not be able to fully leverage the strategic value they offer; too late, and you might miss critical opportunities for growth or risk financial mismanagement. Scalability is another critical consideration—your Fractional CFO services should be able to scale up or down based on your business's evolving needs.

A vital part of an understudy's academic progression are GCSE exams. These exams put to the test the knowledge and skills learned over the course of the course, and they play a crucial role in determining the future educational and professional prospects of the understudy.
What Happens If You Miss a GCSE Exam? However, life can be unpredictable, and sometimes unforeseen circumstances may arise, causing a student to miss one or more GCSE exams. In this blog, we will explore what happens if a student misses a GCSE exam and the potential consequences they may face.
1. Notify the School Immediately

Typically, schools have established protocols for reporting exam absences, and it's imperative to adhere to these procedures diligently.
2. Medical Evidence or Valid Documentation

Providing appropriate evidence strengthens the student's case and can be crucial in avoiding potential complications.
3. Consideration for Special Circumstances
Schools and examination boards understand that certain circumstances can hinder a student's ability to take an exam as planned. They may take these special circumstances into account and provide the student with options such as a deferred exam or special consideration during the grading process.
4. Rescheduling the Exam
In some cases, schools may offer an opportunity to reschedule the missed GCSE exam. This is usually done on a case-by-case basis and depends on the school's policies and the circumstances surrounding the absence.
5. No-Shows Without Valid Reasons
A student is likely to obtain a grade of "absent" or "no-show" for a certain GCSE test if they miss it without an acceptable excuse or fail to produce the required documents. Their overall GCSE results may suffer as a result of this.
6. Impact on Grades

If a student's absence from a GCSE exam significantly affects their grades or if they miss multiple exams, they may have the option to retake the entire GCSE course or the specific subject at a later date. However, this might mean delaying their academic progression.
8. Explaining Absences to Universities or Employers
When applying for further education or jobs, students may be required to provide their GCSE results as part of their academic or professional qualifications. If there are gaps or absences in the GCSE results, students may need to explain the reasons behind the missed exams to universities or potential employers.

However, the detrimental effects can be reduced with fast communication, reliable documentation, and appreciation from schools. Understudies should be responsible for their scholastic advancement and search out the right assistance when they need it.In the end, conquering these obstacles can help kids develop more character and perseverance, preparing them for future efforts.
Though missing a GCSE exam is not ideal, it is not the end of the road, keep in mind.
How much does it cost to retake GCSE?
The cost to retake GCSE exams varies depending on the exam board and the school or examination center. On average, the cost for retaking a GCSE exam can range from £25 to £40 per subject. However, it is essential to check with the specific exam board or school for the most accurate and up-to-date information on exam fees.
What counts as a fail at GCSE?
In GCSE examinations, the grading system ranges from 9 to 1, with 9 being the highest grade and 1 being the lowest. Generally, a grade between 9 and 4 is considered a pass, while a grade 3 or below is considered a fail. However, the exact definition of what constitutes a "fail" at GCSE may vary depending on the context and individual circumstances. Some colleges and employers may have specific grade requirements for certain courses or positions, so it is essential to check their criteria to determine what is considered a pass or fail in those situations.
Is it OK to resit GCSE?
Yes, it is absolutely okay to resit GCSE exams. Many students choose to resit their GCSE exams to improve their grades or achieve better results in specific subjects. Resitting allows students to have a second chance at obtaining the grades they desire and can open up more opportunities for further education or future career paths. Whether a student is unhappy with their initial results or simply wants to enhance their qualifications, resitting GCSE exams is a common and acceptable practice.
How many GCSEs do you need?
The number of GCSEs required can vary depending on individual goals and plans. In the UK, students typically study for a minimum of 9 to 10 GCSE subjects. However, the exact number needed may depend on factors such as specific college or university entry requirements, career aspirations, and personal preferences. Some institutions or courses may have specific subject requirements, while others may look at the overall GCSE results. It is essential to research the specific requirements of the educational or career path you are interested in to determine the exact number of GCSEs needed. |
Low-voltage landscape lighting can add beauty and elegance to your outdoor spaces after dark. Using flexible PEX tubing makes installing low-voltage lighting an easy do-it-yourself project. With some planning and basic materials, you can create a customized landscape lighting system to highlight trees, pathways, and architectural features in your yard.
Selecting the Lighting Fixtures
When working with low-voltage lighting, the fixtures typically run on 12V power. This makes them safe to install outdoors, even in damp conditions. There are numerous fixture styles to choose from:
Path lights - Illuminate walking paths and steps. Small and lightweight to place along pathways.
Spotlights - Focus light on specific landscape features. Adjustable heads let you aim the light.
Flood lights - Provide broad illumination. Good for open areas like patios.
Deck lights - Recessed fixtures that mount to wooden decks. Subtle accent lighting.
Step lights - Line steps for visibility and safety.
Tree uplighting - Light pointed up into trees to create dramatic effects.
Consider factors like fixture brightness, spread of light, and finish to find options that suit your needs. Outdoor-rated LED bulbs are the most durable and energy-efficient choice.
Planning the Layout
Carefully plan where to place the lighting fixtures for the best effects. Here are some tips:
Illuminate pathways - Ensure safe navigation after dark. Place path lights about 5-10 feet apart.
Highlight architectural features - Spotlight interesting details on buildings, fences, and decks.
Accent vegetation - Shine spotlights on ornamental plants and uplight larger trees.
Light gathering areas - Use flood lights to brighten seating areas, pools, and patios.
Create depth - Place fixtures at varying distances from boundaries to make landscapes appear larger.
Mix fixture types - Use path, spot, and flood lights together for depth and interest.
Consider angles - Position fixtures to reduce glare and light pollution. Focus lighting downward.
Using PEX Tubing for Wiring
PEX, or crosslinked polyethylene tubing, makes installing low-voltage landscape wiring much simpler than burying individual wires.
Benefits of PEX tubing
Flexible - Easy to snake through gardens and around obstacles.
Durable - Resists moisture, mildew, and UV rays when used outdoors.
One conduit - No need to dig multiple wire trenches.
Neat appearance - Tubing won't leave visible above-ground wires.
How to work with PEX
Purchase UV-resistant 1/2" PEX tubing to run low-voltage lighting wire through.
Determine the tubing routes between your transformer and each light fixture.
To go around corners, use angled PEX fittings. You can also coil extra tubing length underground.
At each fixture, leave an access coil of tubing to splice wires.
Use PEX elbows and tees to create branches to multiple fixtures.
After pulling wires through, cap the ends so moisture won't enter.
Electrical Requirements
Low-voltage lighting systems have three basic electrical components:
Transformer - Converts 120V household current into 12V power. Select a transformer with enough wattage for all fixtures.
Wiring - Typically 16 or 18 gauge, 2-conductor cables tailored for low-voltage systems. Run through the PEX tubing.
Fixtures - The path lights, spotlights, deck lights etc. Should be 12V models compatible with the transformer output.
Calculating electrical load
Add up the wattage of all fixtures to determine the total wattage needed from the transformer. Generally, allow 20-30% extra capacity. Also consider:
Cable length - Longer wire runs create more resistance and reduce voltage.
Future expansion - Size the transformer to add more lights later if desired.
Dimming - Many transformers have dimmers to lower light levels. This reduces wattage.
Safely connecting components
Choose an appropriate outdoor location for the transformer and mount it to a wall or post.
Run the PEX tubing from the transformer to the light locations. Leave access coils.
At each fixture, splice the wires between the main cables and the light wires with gel-filled connectors.
Use wire nuts to join wires at the transformer. Follow the instructions for the output connections.
Test the lights and troubleshoot any issues before burying the PEX tubing underground.
Installing the PEX Tubing
Once the lighting plan is complete, it's time to start the installation:
Dig trenches about 6-12 inches deep along the planned PEX tubing routes using a shovel or trencher.
Laying the tubing
Carefully unroll the PEX tubing and lay it into the trench.
Position any turns and elbow fittings as needed.
At light locations, leave a few feet of coiled access tubing above ground.
Running the wire
Use gel-filled wire nuts to connect the main low-voltage wire ends to the transformer output.
Carefully pull the main wires through the PEX tubing so they extend to each light fixture.
At each light, pull about 12" of wire from the access coil and splice it to the light wires.
Finishing up
Test all lights and adjust any fixtures or splices as needed.
For an invisible look, bury the access tubing coils. Leave wires exposed at fixtures.
Backfill the trenches with dirt, slope the surface for drainage, and restore any disturbed grass or plants.
Proper planning is crucial for a successful and attractive low-voltage landscape lighting system. Take time to carefully design the lighting layout and select the perfect fixtures before beginning the installation using PEX tubing. With some patience and attention to detail, you can create beautiful and functional outdoor lighting to enjoy for years to come. Let your imagination and creativity shine! |
European Travel Etiquette: How to Respect Local Customs and Culture
Traveling to Europe is an exciting adventure, but it's important to remember that each country has its own unique customs and culture. Respecting these customs is essential to having a positive and respectful travel experience. Here are some tips on how to navigate European travel etiquette and show respect for local customs and culture.
Dress Appropriately
In many European countries, especially in places of worship and formal settings, dress codes are important. It is important to adhere to local dress standards in order to show respect for local customs. In some countries, it is necessary to cover the shoulders, knees, and cleavage when visiting religious sites or entering certain establishments. It's always a good idea to do some research on the local dress customs before traveling to a specific destination.
Punctuality is highly valued in many European countries. Being on time for appointments, meetings, and social outings is a sign of respect. It is considered rude to be late to a planned event or gathering, so it's important to make an effort to arrive on time.
Table Manners
European dining etiquette varies greatly across different countries, but there are some general rules that apply throughout the continent. These include keeping your hands on the table, using cutlery properly, and waiting for the host to start eating before you begin. It's also important to keep in mind that tipping customs can vary significantly from country to country, so it's best to research the local norm to ensure you are showing the appropriate level of gratitude for good service.
While English is widely spoken in Europe, it's important to remember that not everyone will speak it fluently. Making an effort to learn a few basic phrases in the local language, such as "hello," "please," and "thank you," can go a long way in showing respect for the local culture.
Respecting Personal Space
In many European countries, personal space is highly valued. It's important to be mindful of the space of those around you, especially when in crowded areas such as public transportation or busy city streets. It's also important to be aware of local customs regarding physical contact, as some cultures are more reserved than others.
Religious Customs
Many European countries are home to a variety of religious traditions and customs. It's important to respect local religious practices, whether you are visiting a historic church or partaking in a religious festival. This includes being mindful of dress codes and adhering to the rules and traditions of the religious institutions you are visiting.
Overall, the key to respecting local customs and culture in Europe is to approach each new experience with an open mind and a willingness to learn and adapt. By being considerate and respectful of the customs and traditions of the places you visit, you can ensure that your travels are enjoyable and positive for both yourself and the local people you encounter. Remember, your actions as a traveler have an impact on the places you visit, so it's important to tread lightly and show respect for the culture and customs of the locals. |

Best describes the aftermath of pontiac's rebellion

Pontiac's Rebellion was a war waged by Indians of the Great Lakes region against British rule after the French and Indian War. The Indians, who had formed alliances with the defeated French, were dissatisfied with treatment from British officials. Unlike their French allies, British officials entrusted with Indian relations refused to offer gifts to tribal leaders such as guns, gunpowder, and ammunition. Furthermore, English settlers began displacing Indians from their land. While French settlers and Indians seemed to live in relative harmony, the sheer number of English settlers that descended on the region prompted many Indians to support war. The Indians began to feel as if the British were preparing for war against them. The rebellion lasted three years, from 1763 to 1766. Much of the war's terrible violence occurred in 1763; the remaining years were spent formulating peace treaties. The war was named after Pontiac, chief of the Ottawa tribe. Indians from many tribes including the Ottawa, Ojibwa, Shawnee, Miami, Huron, Seneca and Potawatomi participated in the uprising.

lone hero cares for abandoned animals of Fukushima The untold human suffering and property damage left in the wake of the Fukushima disaster in Japan has been well-documented, but there's another population that suffered greatly that few have discussed – the animals left behind in the radioactive exclusion zone. One man, however, hasn't forgotten – 55-year-old Naoto Matsumura, a former construction worker who lives in the zone to care for its four-legged survivors.

Chimps, Like Humans, Act Out When They Know They're Right by Monica Joshi Chimpanzees are marvelous creatures. Jane Goodall has spent her whole life trying to understand them. As chimps share over 98 percent of our DNA, they have been known to make and hunt with spears. Researchers at Georgia State University, Agnes Scott College, Wofford College, and the University at Buffalo, The State University of New York have discovered that chimpanzees not only are capable of metacognition, but also can adjust their behaviour based on this metacognition. Published in the journal Cognition, their findings suggest that this reflects a form of cognition control that underlies intelligent decision-making across species. Humans are able to report confidence in a few different ways such as: using an oral reportage of confidence or lack thereof, numerical rating scales, and body language. In the course of the study, three chimps were tested using a series of computerized tests. Audrey Parrish, researcher from Georgia State pointed out that:
Earth - Rats will save their friends from drowning Saving another person from a life-or-death situation is something many of us do instinctively. But it's not unique to humans. Many primates will also help each other out. They are our closest relatives, so it's likely that our ape-like ancestors behaved in similar ways. In other words, our willingness to save others is an ancient trait, which modern humans have inherited. This trait may go back a surprisingly long way. When one was soaked in water, another rat quickly learned how to operate a lever that would allow it to escape to a safe and dry area. They did so even in the presence of a tempting chocolate treat, foregoing the lever that would release the food in favour of the one that would save the drowning rat. The rats therefore engage in helpful "prosocial behaviour" even if there was no apparent reward. Past experience played a role too. But when there was nobody to save, or the distressed rat was replaced with an inanimate object, the rats no longer pressed the lever.
Incredible Photos Of Mongolian Tribe Show Deep Bond With Animals The Dukha tribe from Mongolia are one of the few remaining "lost" tribes that have completely escaped the realities of the modern world. They are best known as reindeer herders, but their connection with the animal world goes beyond reindeer. The magical photographs were taken by Hamid Sardar Afkhami who travelled to Khovsgol, Mongolia to photograph one of the few Dukha families that remain. Matadornetwork.com reports: The children of the tribe are raised surrounded by reindeer, and they build a close connection. The Dukha do not typically eat the reindeer unless the animals are no longer capable of helping them hunt or travel.
Disappearing Rusty Patched Bumble Bee is One Step Closer to Getting Protection Conservationists have been pushing for protection for a bumble bee that's disappearing at an alarming rate and are now hopeful that it will get the help it needs as the first bee species to be protected under the Endangered Species Act. The rusty patched bumble bee, which can be identified by a rust-colored patch on its abdomen, was once a commonly seen pollinator from the midwest to the east coast, but scientists believe that it has disappeared from 87 percent of its historic range and that its population has declined by a startling 95 percent in just the past few decades. According to the Xerces Society for Invertebrate Conservation their main threats include pesticides, habitat loss, climate change and disease, but one of their biggest problems now may also be attributed to the spread of pathogens from bees who are raised and sold commercially to wild bumble bees. In 2013, the Xerces Society the U.S.

5 Great Reasons to End Dolphin Captivity Whale and dolphin advocates have been fighting against captivity for a long time. Since the documentary Blackfish started making waves, the plight of captive cetaceans has reached a much wider audience and has forced us to take a hard look at whether or not this is something we should be supporting. In a series of new papers, Dr. Joan Gonzalvo, who has been studying dolphins in the wild for more than 15 years, examines some of the reasons why captivity needs to end and dispels some of the myths the industry uses to keep people coming back. Gonzalvo's most recent paper, which was just released by the Born Free Foundation and the Italian animal protection organization, Lega Anti Vivisezione, challenges the captivity industry and highlights five of of the main reasons we shouldn't be keeping dolphins in tanks: They Are IntelligentThey Are Social BeingsThey Are Far-Ranging PredatorsThey Are Psychologically and Emotionally SensitiveCaptivity Does Not Support Education or Conservation
Ringling Bros. and Barnum & Bailey CEO Will Breed Elephants The day that Ringling Bros. and Barnum & Bailey announced that they would retire their performing elephants (within three years) was a huge victory for animal advocates. But a new interview with the circus' ringmaster, also known as the CEO, casts a small shadow on that victory. An Inside Look Into the Center for Elephant Conservation Ringling CEO Kenneth Feld sat down with National Geographic to discuss the Center for Elephant Conservation, where the current performing Asian elephants will retire — if we can call it retirement. The relatively flat and treeless 200-acre Florida elephant center already houses 30 Ringling retired elephants. Feld will own the largest collection of endangered Asian elephants in the Western Hemisphere. Feld falls short of calling his elephant center a sanctuary and with good reason. Unlike other reputable sanctuaries, Feld breeds his elephants for a life of captivity. Captivity also takes a toll on the physical well-being of elephants. Take Action! |
Antifederalist Paper 69 – The Character of the Executive Department versus Federalist Paper 69 – The Real Character of the Executive Department "On the whole, it would be, in my opinion, almost as well to create a limited monarchy at once, and give some family permanent power and interest in the community, and let it have something valuable to itself to lose in convulsions in the state, and in attempts of usurpation, as to make a first magistrate eligible for life, and to create hopes and expectations in him and his family of obtaining what they have not." -Antifederalist Paper 69. The Federal Farmer. "Would not the prospect of a total indemnity for all the preliminary steps be a greater temptation to undertake and persevere in an enterprise
I Agree… "The Federalist No. 84" and "The Anti-Federalist No.84", both have their views on what should happen to our government. Whether it is to add a bill of rights or not, but I agree with the writer of "The Federalist No.84" because if the Constitution is adopted, then it will be our Bill of Rights, also based on other countries' bill of rights then it may argue with a semblance of reason. Because I have read both sides of the discussion, I can see who is wrong and why.
Ernie Law Zink 3° US History 15 September 2016 DBQ Essay When the delegates met in 1787 they aimed to fix the national government. The previous governmental charter, the Articles of Confederation, failed because it was just too weak and wasn't getting the job done. Under the Articles of Confederation, there was no court system, no chief executive, and there was no particular way for the central government to force states to pay their taxes. By creating the Constitution, it would build a stronger central government and would be able to hold the nation together.
Federalist Paper Number 10: This federalist paper was written by James Madison and focused on the idea of factions. He begins by acknowledging that factions will always exist. He believes the most common source of faction is in unequal distribution of property.
There was discussion of judicial review in Federalist No. 78, written by Alexander Hamilton, which explained that the federal courts would have the power of judicial review. Hamilton stated that under the Constitution, the federal judiciary would have the power to declare laws unconstitutional. He also stated that this was appropriate because it would protect the people against abuse of power by Congress.
James Madison opposes another paper entitled "Federalist Number 51". This paper addresses issues on liberty, the structure of the government, and the branches of the government. Madison wanted to assure that all branches have the same amount of power and authority in order to gain independence in a particular branch. As citizens, we are supposed to elect the president, the legislators, and the judges. However, the judicial system does not work that way.
Jonah Brenner Federalist Paper 33 Alexander Hamilton begins Federalist Paper 33 by stating the following clauses: The Constitution authorizes the national legislature "to make all laws which shall be necessary and proper for carrying into execution the foregoing powers, and all other powers vested by this Constitution in the government of the United States, or in any department or officer thereof." Also "the Constitution and the laws of the United States which shall be made in pursuance thereof and all treaties made, or which shall be made, under the authority of the United States, shall be the supreme law of the land, and anything in the constitution or laws of any State to the contrary notwithstanding." These two clauses have been subject to intense accusations against the
In Federalist No. 78, Alexander Hamilton lays out his vision for how the Supreme Court of the United States should function. In it, he assures that one of the key roles of the Supreme Court will be to check the constitutionality of congressional legislation in order to protect the individual rights of the people. However, in his opinion for the Marbury v. Madison case in 1803, Chief Justice John Marshall interprets the power of judicial review from Article III of the constitution, in a way in which the court becomes a powerful branch of government. With Marshall's interpretation, the court is able to "strike down" legislation by the command of the people which is embedded in the Constitution (O'Brien 173). Hamilton intended for the court to
The Federalist No. 10" is a persuasive argument written by James Madison in an attempt to ratify the Constitution. He wrote a series of documents called the Federalist Papers under a pseudonym to convince others to approve of the Constitution. He says that factions are not good for America, neither is a pure democracy. Madison provides extensive arguments and remedies for the problems he is addressing. James Madison is attempting to ratify the Constitution by analyzing the way to deal with factions, comparing a republic to a democracy, and by comparing a small government to a large government.
Kimberly Paul Mr. Brandenburg 030817 Much like the Democrats and Republicans of today, Federalists and Anti-Federalists had diverging opinions on how the nation should be governed. Federalists had the utmost faith in the people and believed that they were the only ones capable of governing the nation fairly and efficiently. They were avid believers of a strong central government, a central bank, and an army. Federalist No. 39 states: "It is essential to such a government that it be derived from the great body of the society, not from an inconsiderable proportion or a favored class of it," proving that they were in favor of central, unionized government.
The Federalist papers are a series of documents created by Alexander Hamilton, James Madison, and John Jay. The papers discuss how the new government system that was beginning to be developed in the 1780s was going to work and be carried out. The authors wanted to write the Federalist papers to create a document that would help to interpret the United States constitution. Federalist papers #10 and #51 were both written by James Madison.
James Madison, founding father and fourth president of United States wrote the federalists paper number 10 in favor of the constitution. He believes that constitution is the only way to keep balance and control any problem this country faces. He uses faction as an example and talks about how it can cause problems but most importantly how to deal with the problems. He defines faction as groups of people who came together to promote their own interests and opinions. He said that these groups take advantage of the public and violate their rights.
If we do not win this debate, our liberation from Great Britain would have been pointless. I support the Antifederalist for this exact reason. We need a Bill Of Right to protect us from the government crushing hand. The Federalist want us to go along with a promise! Just a set of pretty words and an system of checks and balances!
One of the changes in American politics was the changing role of the federal government. This is evident in James Madison's veto message from 1817 where he expresses his difficulty in reconciling a bill for internal improvements with the Constitution (POV - Doc 2). This document reveals a shift in the understanding of the federal government's role in the economy and infrastructure, and the growing debate over the
The Federalist Papers No. 51 were written by either James Madison or Alexander Hamilton to address the various concerns the residents of New York had with the newly formed government provided to them and the other colonies via the Constitution, more specifically the purpose of the new structure of government, the separation into different branches of the government and each branch's reliance on the people, and the system of checks and balances and duties placed on each branch among other things. The Federalist Papers No. 51 also explained the necessity of the government outlined in the Constitution and why the founding fathers found it best to arrange the new government the way they did. One of the main ideas addressed in the Federalist
In the Federalist Paper number 51, Madison writes to the people of New York to explain that it is necessary for a separation of powers between the departments of the government. Madison, with the help of Hamilton, wrote the Federalist Papers to explain sections of the Constitution. In Federalist Paper number 51, Madison explains that the government does not have a strong structure on the outside, but creating a firm structure within the government could be a solution. The firmer structure would be the separation of powers. In order for the people to get a better idea and make a more accurate judgement about the separation of powers, Madison shares observations and puts them into simpler terms. |

FS Jeanne d Arc (R97)
Helicopter Carrier
France | 1964
"Jeanne d Arc served in the helicopter carrier role with the French Navy from 1964 to 2010, since decommissioned and awaiting her fate."
Authored By: Dan Alex | Last Edited: 11/09/2018 | Content ©www.MilitaryFactory.com | The following text is exclusive to this site; No A.I. was used in the generation of this content.
When the French Navy required an all-modern aircraft carrier during the tumultuous Cold War years, it selected a conventionally-powered helicopter carrier as the FS Jeanne d'Arc (R97). The vessel saw its keel laid down in 1959 with official launching in 1961. She was formally commissioned into French Navy service in 1964. While an aircraft carrier in the general sense, the Jeanne d'Arc was a true helicopter carrier, her air wing composed of nothing but rotary-wing aircraft. Her onboard facilities supported up to ten various helicopter types depending on mission requirements. Jeanne d'Arc served in the helicopter carrier and training roles until finally decommissioned on September 1st, 2010. During her time at sea, Jean d'Arc she was given the nickname of "La Jeanne" and based out of Brest along the French northwest coast. Today (2014), the decommissioned vessel awaits her fate - most likely to be scrapped.
Originally, Jeanne d'Arc (R97) was to carry the name of "La Resolue" due to the fact that the original 1930s-era FS Jeane d'Arc cruiser remained in active French navy service. However, the original ship was decommissioned during 1964 in time for the new vessel to take up the name. Jeanne d'Arc (R97) served as the only vessel of her class.
As built, Jeanne d'Arc displaced 10,575 tons under standard load and 12,365 tons under full load. Her length measured 597 feet with a beam of 79 feet and draught of 25 feet. Propulsion was conventional in utilization of two geared steam turbines generating 40,000 horsepower output to 2 x shafts. This arrangement allowed for a maximum sea-going speed of 28 knots and range out to 7,500 nautical miles. Her complete crew complement numbered 627 to include 31 officers. She fielded a variety of sensors and systems including air/surface search radar, sonar, fire control, and navigation set along her main mast. Her defensive suite was led by 6 x Exocet-38 series anti-ship missile launchers (two banks of three launchers) with 2 x 100mm autocannons (the guns eventually removed in 2000). Short-range defense was through 4 x 12.7mm heavy machine guns.
The most important quality of this (and any) helicopter carrier was the flight deck - measuring 203.4 feet wide - designed to manage several helicopters simultaneously (depending on size). Hangar facilities were available for full-service work below the flight deck with an aft-elevator allowing the necessary access. Storage room also allowed the vessel to carry an array of munition options for her helicopter fleet.
Having only to serve helicopter aircraft, the general arrangement of Jeanne d'Arc was quite different from other aircraft carriers of the period. Her design was given a flight deck set over the stern with a smaller quarterdeck section fitted. The platform extended forwards to about midships. The bridge was set high on the sole superstructure which, itself, was fitted just ahead of amidships with a single smoke funnel seen aft. Her defensive armament was centralized ahead of the bridge superstructure along a sub-deck. The autocannons were at single turrets straddling either side of the bridge superstructure with the Exocet missile launchers in a pair of outward-facing, three-launcher units just ahead and in between.
During the course of her career, Jeanne d'Arc served training, support, and combat roles. During peacetime, she was a school for officer cadets but always reserved the capability to be readied for wartime service - primarily in support of amphibious operations where her helicopter-launching capabilities could be put to good use. Additionally, her internal space was such that the vessel could support up to 700 infantry prior to landing this force ashore by air or landing craft (LCVP). When stocked with Anti-Submarine Warfare (ASW) helicopter types, the carrier could also be called upon to hunt enemy submarines down through sonar and torpedoes.
The final cruise of Jeanne d'Arc (R97) was in 2009, her tenure fully ended in 2010.

Poker is a card game in which players place bets using chips. They are dealt two cards, and then five community cards are placed face up on the table (these are called the flop). The object of the game is to form the highest ranking poker hand from the combination of the player's two cards and the five community cards. Whoever has the best hand wins the pot, the total amount of bets made by all players in a given round. The first player to raise their hand after the flop is considered the betting leader and has a choice of calling, raising or folding.
The game of poker involves a number of different emotions. It tests a player's patience, concentration and focus. It also forces them to assess the strengths and weaknesses of their opponents. In addition, it requires a good deal of deception. This is especially important when it comes to bluffing. It is important for a player to be able to read their opponent's body language and facial expressions in order to determine what they are holding.
In poker, as in many other areas of life, decisions must be made under uncertainty. It is necessary to be able to evaluate the probability of various scenarios and to calculate the odds. This is a skill that can be applied in business, gambling and sports as well as in everyday life. In fact, the decision-making skills learned through playing poker can benefit other aspects of a person's life as well as their overall mental health.
One of the reasons why poker is such a popular game is because it allows players to practice their mental agility and analytical thinking. It is also a fun way to pass the time and socialize with friends. However, many people don't realize that poker has a number of cognitive benefits that can improve a person's life.
Mental and emotional strength
In addition to the above, poker is a game of incomplete information. You don't know the cards your opponents are holding, or even their intentions. This is why it's important to be able to make good decisions when your opponent is acting irrationally. It is also important to be able to control your emotions, and keep a "poker face" at all times.
The physical and mental endurance required to play poker means that players are often exhausted by the end of a session. This is particularly true if they have been involved in a long tournament. This is because they have used a lot of brain power to play the game, and their bodies require rest in order to function optimally. Moreover, the high levels of stress and anxiety experienced while playing poker can leave them feeling anxious and stressed in other parts of their lives. This is why it's so important to find a balance between your poker playing and other activities. This will help to prevent burnout and ensure that you're able to enjoy the game for as long as possible. |

New potential citrus germplasm accessions may be received as seed rather than budwood, thereby reducing phytosanitary risks. However, trueness-to-type may be an issue with seed materials because many varieties produce both apomictic (nucellar) and sexual (zygotic) embryos and most citrus is fairly heterozygous. To identify nucellar seedlings of polyembryonic types and to retain these as representing the type, we screened 1340 seedlings from 88 seed sources for markers amplified with two inter-simple sequence repeat (ISSR) primers. Sixteen seed sources produced no seedlings classified as being of nucellar origin. Among the remaining seed sources, seedlings classed as nucellar were identified for potential addition to the collection. In 37 accessions, both nucellar and zygotic seedlings were detected, and in some cases both types were retained. Inclusion of established accessions of the same cultivar group in the analysis allowed an initial assessment of similarity to existing accessions. This technique improved the efficiency of acquiring new germplasm of polyembryonic types by seed. The method identifies those seed sources that produce few or no nucellar seedlings, but it is not useful for determining which seedlings of monoembryonic types should be retained in collections.
ISSR markers were analyzed to study phylogenetic relationships among 46 Citrus L. accessions representing 35 species. A dendrogram based on the unweighted pair-group method, arithmetic average cluster analysis was constructed using a similarity matrix derived from 642 polymorphic ISSR fragments generated by 10 primers. These 46 accessions could be classified into five major groups: 1) C. indica Tan.; 2) C. maxima (Burm.) Merrill; 3) lemon [C. limon (L.) Burm.] or lime [C. aurantifolia (Christm.) Swingle] type accessions; 4) C. halimii B. C. Stone; and 5) sour orange (C. aurantium L.), mandarins and their hybrids. Group 5 was further divided into three subgroups. Although some previous work had grouped it with mandarins, C. indica appeared to be a distinct genotype or species that was not close to mandarins. C. tachibana Tan. grouped closely to mandarins. C. vulgaris Risso was not related to sour orange but was similar to accessions usually classified in the lime or lemon group. Sour orange and its hybrids, C. nippokoreana Tan., C. hanayu Hort. ex Shirai, C. sudachi Hort. ex Shirai, and C. yuko Hort. ex Tan. had close phylogenetic relationships with mandarins. Although the mandarin accessions studied were divergent in morphology, the genetic distances among them were relatively small. Relationships among these Citrus accessions revealed by ISSR markers were generally in agreement with previous taxonomic classifications. |
What Is a Test Environment?
A test environment is a setup of software and hardware on which the testing team assesses an application or system during and after its development. It is designed to mimic the production environment closely but is specifically configured for testing purposes. This ensures that the application can be tested in conditions that are as close as possible to what end-users will experience, which is crucial for identifying and correcting issues.
This environment includes all the necessary elements to run the application, such as hardware specifications, software, databases, network configurations, and any other required services. Its primary purpose is to simulate real-world conditions, allowing testers to identify and fix issues before the software is released to end-users.
Creating a dedicated test environment allows developers and testers to verify functionality, performance, and security of the application in a controlled setting. This isolation from the production environment protects live systems from unintended impacts and enables thorough testing without disrupting ongoing operations.
This is part of a series of articles about environment variables
In this article:
The Importance of Test Environments
A well-configured test environment directly impacts the quality, reliability, and stability of the software product. It enables teams to conduct tests that would be risky or impossible in a live environment, such as stress testing or exploring security vulnerabilities. By providing a safe space for these activities, organizations can ensure that their software meets the highest standards of quality before it reaches the public.
Test environments allow for continuous testing and integration, facilitating agile development practices. They enable teams to quickly identify defects and assess the impact of changes, fostering a culture of continuous improvement. This accelerates the development process and reduces the cost and effort required to fix issues after release.
7 Types of Testing Environments
Testing environments can be split into different categories based on the types of testing they support. Note that these are ideal types—in reality, most testing environments support more than one of these types of testing.
1. Integration Testing Environment
An integration testing environment is specifically set up for testing the interfaces and interaction between different components of a software system. This environment is useful for identifying issues that might not be apparent during unit testing, such as data format mismatches, interface inconsistencies, and dependency problems.
Integration testing ensures that combined parts of an application work together smoothly, providing a seamless experience for the user. This environment often requires a complex setup that mirrors the production environment's infrastructure to accurately evaluate the system's behavior including its integrated components.
2. System Integration Testing Environment
System Integration Testing (SIT) involves verifying the complete and integrated software system to ensure it meets specified requirements. This environment extends beyond integration testing by evaluating the system's overall behavior and interaction with external systems. It ensures that all system components, including software, hardware, and third-party services, work together as intended.
SIT is particularly important in complex systems where different technologies and platforms need to seamlessly interact. This testing phase helps identify issues related to system configuration, external dependencies, and cross-system interactions, ensuring a smooth and coherent operation of the entire ecosystem before deployment.
3. User Acceptance Testing Environment
User Acceptance Testing (UAT) is conducted in an environment that closely replicates the production setting to validate the software with the end-user's perspective in mind. It focuses on ensuring that the application meets the business requirements and is ready for real-world use.
UAT is typically the final step before the software release, providing a critical validation of its functionality, usability, and performance from the user's standpoint. This environment often involves actual users or stakeholders who perform tasks and scenarios that the software is expected to support in the production environment. UAT helps in capturing feedback on user experience.
4. Performance Testing Environment
A performance testing environment is designed to evaluate how the application behaves under various conditions, including high load, concurrent access, and limited resources. This environment allows testers to simulate different scenarios, such as peak usage periods, to assess the application's responsiveness, stability, scalability, and resource utilization.
This type of environment is critical for ensuring that the software meets performance criteria and can handle real-world operational demands. Equipped with specialized tools for monitoring and generating load, it helps identify bottlenecks, optimize resource usage, and ensure that the application can maintain its performance levels under expected and peak conditions.
5. Quality Assurance Environment
A Quality Assurance (QA) environment is dedicated to systematic testing to ensure the software meets quality standards and is free from defects. It encompasses various testing types, including functional, non-functional, regression, and security testing, aiming to thoroughly evaluate all aspects of the software.
QA environments focus on identifying and addressing issues before they impact the user experience. The QA team applies standardized testing methodologies and tools to assess the software's quality. It's a controlled setting where test cases are executed according to test plans, with the results critically analyzed to guide further development and improvements.
6. Security Testing Environment
A security testing environment is specifically designed for identifying vulnerabilities and assessing the software's resilience against attacks. It's equipped with tools and technologies for conducting a wide range of security assessments, including penetration testing, vulnerability scanning, and risk assessments.
This environment allows testers to safely simulate attack scenarios and identify potential security weaknesses without compromising the actual production environment. The focus in the security testing environment is on protecting data integrity, confidentiality, and availability, ensuring that the application adheres to security best practices and regulatory standards.
7. Chaos Testing Environment
Chaos testing, also known as fuzzing or fault injection testing, involves introducing unexpected failures or conditions to assess how the system responds. The chaos testing environment is designed to simulate these adverse scenarios in a controlled manner, allowing teams to evaluate the application's resilience, fault tolerance, and recovery processes.
This testing is crucial for distributed systems and applications operating in cloud environments, where the potential for unpredictable failures is higher. By deliberately disrupting normal operations, chaos testing helps identify weaknesses in the system's architecture and operational procedures.
Best Practices When Setting Up Test Environments
There are several measures that should be taken when setting up a testing environment.
Replicate Production Conditions When Possible
It's important to replicate the production conditions as closely as possible. This includes hardware specifications, software versions, network configurations, and any external integrations. By mirroring the production environment, teams can ensure that the testing scenarios accurately reflect real-world conditions, leading to more reliable and relevant test results.
Use Mock Services and Data When Necessary
In some cases it may not be possible, or necessary, to include all elements of the production environment. In this case, mock services and data are an effective way to simulate external dependencies and complex scenarios without the need for full-scale production replicas.
Mocking can be used to mimic third-party services, APIs, or even specific system states, allowing for comprehensive testing of interactions and behaviors. This approach is particularly useful for testing in early development stages or when access to real services and data is restricted or impractical.
Maintain Isolation
Maintaining isolation between different test environments and the production environment is crucial for ensuring the integrity of testing processes and protecting production systems. Isolation prevents test activities from impacting live operations and ensures that tests are conducted in a controlled and secure manner. This involves using separate hardware or virtualized environments, managing access controls, and ensuring that test data does not contaminate production data.
Automate Setup and Teardown
Automation tools can rapidly provision environments with the required configurations, dependencies, and data, making it easier to conduct multiple tests or parallel testing scenarios. Automation also ensures that environments are reset to a known state before each test, reducing the risk of test contamination and ensuring that each test starts with the correct setup.
Use Environment Variables Carefully and Securely
Environment variables play an important role in managing configurations across different environments, allowing for flexibility and customization without hard-coding settings. They enable developers and testers to specify variables, such as database connection strings or API keys, that can change between development, testing, and production environments.
However, it's vital to use environment variables securely, ensuring sensitive information is not exposed. This can involve encrypting variables, using secure vaults for storage, or employing configuration management tools that securely handle sensitive data. By carefully managing environment variables, teams can maintain configuration flexibility while safeguarding important information.
Configu: Easy Configuration Management for Environment Testing
Configu is a configuration management platform comprised of two main components, the stand-alone Orchestrator, which is open source, and the Cloud, which is a SaaS solution:
Configu Orchestrator
As applications become more dynamic and distributed in microservices architectures, configurations are getting more fragmented. They are saved as raw text that is spread across multiple stores, databases, files, git repositories, and third-party tools (a typical company will have five to ten different stores).
The Configu Orchestrator, which is open-source software, is a powerful standalone tool designed to address this challenge by providing configuration orchestration along with Configuration-as-Code (CaC) approach.
Configu Cloud
Configu Cloud is the most innovative store purpose-built for configurations, including environment variables, secrets, and feature flags. It is built based on the Configu configuration-as-code (CaC) approach and can model configurations and wrap them with unique layers, providing collaboration capabilities, visibility into configuration workflows, and security and compliance standardization.
Unlike legacy tools, which treat configurations as unstructured data or key-value pairs, Configu is leading the way with a Configuration-as-Code approach. By modeling configurations, they are treated as first-class citizens in the developers' code. This makes our solution more robust and reliable and also enables Configu to provide more capabilities, such as visualization, a testing framework, and security abilities. |
It's best to plant your zucchini in the early summer, when temperatures are at least 70 degrees, because the crop can't tolerate frost or freezing temperatures.
Table of Contents
When can zucchini seedlings be planted outside?
After all the chances of frost have passed, start the seeds indoors four to six weeks before the last frost date and plant them out in the garden. If you want to keep the seeds from germinating, place them in a plastic bag and keep them covered with a damp cloth until you are ready to use them.
How far apart do you plant zucchini seeds?
Plants are arranged in rows 6′ apart. It is possible that wider spacing will allow for easier harvesting. Cucurbit diseases include powdery mildew and downy mildew. Good air flow, insect pest control, and proper plant care are important to avoiding problems. Cuttings can be propagated from seed. Cut the seedlings into 1/2″ to 3/4″ pieces and place them in a warm, dark, well-drained pot.
Water thoroughly and allow to germinate. When the plants are about 3-4 weeks old, remove them from the pot and transplant them into a sunny location. Continue to water and care for them until they are large enough to be transplanted into larger containers.
Do zucchinis need full sun?
Zucchini needs full sun (at least 6 to 8 hours) and consistently moist soil that is high in organic matter. A lot of room to sprawl is required for some zucchini varieties. The bush types are suitable for container gardening and small vegetable gardens. How to Get the Most Out of Your Garden and Garden Soil.
How many zucchini seeds are in a hole?
Each hill has 4 to 5 seeds per hill. If you're planting in rows, add 2 to 3 seeds per hole and 36 to 48 inches apart, depending on the height of your plants. Plant seeds a foot or two above the soil surface. You can also plant seeds at the base of a tree or shrub, but be careful not to damage the roots of the plant.
Do zucchini need a trellis?
The answer is no, it doesn't need to climb to grow. It's easy to grow in a home garden. The plant grows well in containers or traditional potting soil. It depends on what you're trying to do.
If you want to prune the plant, it's best to use a pruning shears to cut off the top of the stem. You can also cut it off with a pair of scissors or a sharp knife. This will make it easier to remove the root ball from the stems.
Do you need 2 zucchini plants to get fruit?
When growing zucchini, the flowers need to be pollinated to form a viable fruit, and each female flower is only open for a single day. No pollination means no vegetable. Your chance of pollination is very low if you have multiple plants growing near each other. First of all, look at the leaves of the plants.
If you see a lot of leaves, then you're probably getting plenty of pollen from the female flowers. You can also count the number of flowers on each plant. The more flowers, the more pollen you'll be getting from each flower.
This is also a good way to tell if a plant is getting enough light, or if it's getting too much. It's also important to note that you don't want to pollinate plants that are too close together, as this can cause the pollen to get stuck in the plant's leaves and cause it to wilt and die.
Should I soak zucchini seeds before planting?
Soak the zucchini seeds for 24 hours before planting. This step improves germination and shortens the time it takes for the seeds to grow. Preheat the oven to 350°F. Line a baking sheet with parchment paper. In a large bowl, whisk together the flour, baking powder, salt, and pepper. Add the eggs, one at a time, beating well after each addition. Whisk in the olive oil and lemon juice.
Pour the wet ingredients into the dry ingredients and stir with a rubber spatula until just combined. Bake for 25 to 30 minutes, or until a toothpick inserted in center comes out clean. Cool on a wire rack for 10 minutes before removing from the pan. Serve warm or at room temperature.
Which end of the seed goes down?
Geo-thermodynamics (thermo = heat, thermodynamic = thermodynamics) explains how seeds grow and how they grow in the environment. It also explains why some seeds are more prone to germination than others. For example, a seed that is exposed to too much heat will grow more slowly than one that isn't.
This is because the seed is more sensitive to changes in temperature than the rest of the plant, which is why it takes longer for a plant to reach a certain temperature. In these cases, the seeds will not grow as fast as they would if they were in a more temperate environment, but they will still be able to grow at a faster rate than a non-stressed plant.
What happens if you plant zucchini too close together?
If you plant too many and don't have plans to give away the excess, you may end up with a lot of zucchini rotting on the plant. In order to prevent that, keep in mind that 2 zucchini plants create 20 pounds of zucchini between them. Don't plant your zucchini too close to other plants, as that can lead to root rot. |

David Johnston has been leading Bass Connections teams into the field to tackle environmental challenges since 2016. His 2023-2024 team will examine how marine ecosystems are evolving in the face of climate change, using belugas in the Churchill region of Hudson Bay in Canada as model organisms. He shared his perspective and advice during a Bass Connections team leader orientation in January 2023.
All Hands On Deck
Over the past seven years, Bass Connections has been a key component of my lab's research, as well as a really important part of my teaching. I've been a leader on several Bass Connections teams and contributed to others, and this work has led to deeply rewarding experiences both for the students and myself.
Most of my teams focus on a particular environmental problem, such as climate change, sea level rise, marine wildlife and the effects of hurricanes on coastlines. My 2023-2024 team will focus on what's happening in the Arctic, looking at sea ice decline and how that affects organisms that live in the coastal ocean and the people that interact with them.
In general, our teams examine challenges in the biology and ecology realm, while also integrating engineering and law or policy. We begin by focusing in on an important ecological question, then examine how we might address it using engineering, and how it could be applied in an environmental management context and what the legal or ethical implications might be.
A lot of our teams have very significant hands-on components that include students working with specific equipment to collect data in the field. We also do a lot of data harvesting from sources out in the world. We begin with plenary sessions where all students are together learning the same things, but in the second semester, students often take control and ownership of a particular aspect of the project.
Mentor-Up, Mentor-Down
Our teams really embrace vertical integration and include faculty, postdocs, Ph.D. students, master's students and undergraduates from a variety of programs across the university. We also work closely with external partners, who are usually either academics that are working in the field in the area we're studying, or natural resource managers.
This opportunity to have a "mentor-up, mentor-down" arrangement is fantastic. When you have good communication, your students learn to be good mentors, and they also learn to provide good feedback to their mentors in the program. I've learned a lot from them over the years, and ultimately, this structure fosters a more modern idea of what leadership is.
One strategy I use to encourage and energize students is asking them to take leadership of an aspect of the project. This helps students learn that they can lead from within a team or organization, and they respond really well to that.
Building Team Community
While we usually recruit students with at least a basic biology background, we really work to try and have a balance of technical versus non-technical folks. That kind of balance helps things move along faster and more efficiently and leads to a better experience for everyone. The non-technical folks bring things to the projects that we had never expected, which is really fantastic.
We'll often have a project manager, whether a Ph.D. student, a postdoc, staff, faculty or combination thereof. In some cases, we have subteams: students may identify particular questions they want to work on, and group up and work on those issues together.
Another component that has been vital for our success has been generating community. Building community can always be a challenge, and while it has been more challenging over the last few years with the pandemic, we have still been able to pull it off. Having a team charter co-produced by the group, setting aside the time to actually get people to talk about how they want to work together has been extremely helpful.
Even more important is setting up expectations for communication. One of the most critical things for us has been making sure that everyone understands what the pace and cadence of those communications needs to be, and working together to decide on that so that everybody has a shared vision they can adhere to.
Part of our community creation has focused on trying to have some type of field experience or trip that the team will go through together, ideally at the beginning of the project. This is the place where students really come together and bond. For example, we took students to the Wright Brothers memorial in Kitty Hawk for some of our remote sensing and drone-based work, which was a really inspirational trip. They got to understand some of the foundations of aviation, and it really helped to bring them together.
The second part of the process is maintaining that community. It's easy for people to drift apart, especially now that we are often working, in our case, between the marine lab and main campus. Developing practices that help make sure that people are connected is key. We use Discord as a tool to have this sort of persistent online communication. I would really recommend that people make use of an online tool like this to maintain persistent communication and bring people together.

Harry Belafonte, 'King of Calypso' and LGBTQ ally, dies at 96
Civil rights icon was grand marshal of 2013 NYC Pride parade
A rainbow banner slung over his right shoulder proudly proclaimed the spry octogenarian a "Grand Marshal 2013" of the New York City LGBT Pride March, joining another vibrant octogenarian, Edith "Edie" Windsor, who was also a "Grand Marshal 2013" that bright sunny June day.
Between the two of them, the honor was an acknowledgement of a long journey not only for LGBTQ rights, but for Harry Belafonte, the beloved African American actor, singer, humanitarian, and the acknowledged "King of Calypso" especially, an honored recognition of his decades of accomplishments and commitment to the civil rights movement and allyship to the LGBTQ community.
Thank you, Mr. B, for all of your years of mentorship, guidance, & lifetime of activism fighting for a better future for all of us. You will be missed by many, but your memory & impact live on. Rest in Power.

"Movements don't die, because struggle doesn't die."
-Harry Belafonte pic.twitter.com/bCArTOtCC2
Born March 1, 1927, in New York, Belafonte was the son of Caribbean-born immigrants, and, growing up, he split his time between Harlem and Jamaica. Dropping out of high school in New York to enlist in the U.S. Navy, he went on to contribute to the war effort from 1944 to 1945.
At the time, the military services were segregated. Belafonte, a Jamaican American, was assigned to Port Chicago, Calif., 35 miles from San Francisco.
During World War II, Black service members were not normally assigned to frontline fighting units. Rather, they were assigned mostly to supporting specialties. His job was to load military ships bound for the Pacific theater.
Just before Belafonte arrived in Port Chicago, Calif., a massive explosion took place, involving military ships loaded with ammunition. About 320 people were killed — two-thirds of them Black sailors.
"It was the worst homefront disaster of World War II, but almost no one knows about it or what followed," he said.
Discharged in 1945, Belafonte returned home to New York. He used his GI Bill benefits to pay for his acting classes at Erwin Piscator's the New School Dramatic Workshop, alongside future actors Marlon Brando, Rod Steiger, Walter Matthau, and what was to develop into lifelong friendship, actor Sidney Poitier.
He performed with the American Negro Theater while studying at the Dramatic Workshop. It was a singing role that resulted in a series of cabaret engagements, and eventually, Belafonte even opened his own club. In 1949, he launched his recording career on the Jubilee label, and in 1953, he made his debut at the legendary jazz club, the Village Vanguard.
He also appeared on Broadway in the 1953 "John Murray Anderson's Almanac," a performance that won him a Tony Award.
Belafonte's first widely released single, which became his signature audience participation song in virtually all of his live performances, was "Matilda," recorded on April 27, 1953.
With a lead role in the film adaptation of Oscar Hammerstein's Carmen Jones, Belafonte shot to stardom. After signing to the RCA label, he released Mark Twain and Other Folk Favorites, which reached the number three slot on the Billboard charts.
His breakthrough third studio album "Calypso" (RCA Victor-1956) became the first long-playing record in the world to sell over 1 million copies within a year. The album introduced American audiences to calypso music and Belafonte was dubbed the King of Calypso.
Besides calypso, he also recorded blues, folk, gospel, show tunes and American standards from "The Great American Songbook" as it is known that included works from George Gershwin, Irving Berlin and Cole Porter.
During the late 1950's he performed during the so-called Rat Pack-era in Las Vegas. He and pianist Liberace, musician and singer Ray Vasquez, and singer Sammy Davis, Jr., were featured at the Sands Hotel and Casino and the Dunes Hotel.
Belafonte also became television's first African-American producer, and his special "Tonight with Harry Belafonte" won an Emmy award in 1960. It was during this time period that he became proactively engaged in the civil rights movement in the 1950s and 1960s including the1963 Freedom March in D.C..
Belafonte befriended the leader of the movement, Dr. Martin Luther King, Jr., with whom he maintained close ties until King's assassination in Memphis, Tenn., on April 4, 1968.

He was also friends with New York Sen. Robert F. Kennedy, often spending time with Kennedy during the latter's run for the U.S. Senate and also during the 1968 presidential campaign, which ended tragically after Kennedy was shot in the kitchen pantry area at the Los Angeles' Ambassador Hotel on June 5, 1968. Kennedy died the next day on June 6, 1968, at Good Samaritan Hospital.
Prior to RFK's assassination, on April 24, 1968, Belafonte interviewed Kennedy while guest hosting for Johnny Carson on the "Tonight Show."
During the 1970s and 1980s, Belafonte refocused his efforts toward humanitarian causes, including joining with famed producer Quincy Jones and singer Michael Jackson on the USA for Africa's "We Are the World," project on March 7, 1985. Rolling Stone wryly noted in its article about the recording and humanitarian fundraiser, that the 46 star vocalists who showed up may have formed the ultimate musical supergroup of all time.
First lady Barbara Bush, standing in for her husband President George Herbert Walker Bush, presented the 12th Annual Kennedy Center Honors to Belafonte, along with his fellow honorees actress Mary Martin, dancer Alexandra Danilova, actress Claudette Colbert and composer William Schuman during a White House East Room ceremony on Dec. 3, 1989.
Two years previously, in 1987, he was appointed as a UNICEF Goodwill Ambassador, replacing Danny Kaye as UNICEF's Goodwill Ambassador. His appointment as Goodwill Ambassador came 27 years after then President John F. Kennedy appointed Belafonte the first member of the entertainment industry to serve as cultural advisor to the Peace Corps.
In 1994, he received the National Medal of the Arts from President Bill Clinton. He has also been awarded the Ronald McDonald House Charities' Award of Excellence in recognition of his humanitarian work and the Audrey Hepburn Humanitarian Award for 25 years of service to UNICEF.
In October 2017 he was awarded the Franklin D. Roosevelt Freedom Medal by the Roosevelt Institute in New York, the citation reading in part:
"In the decades since, you have been involved in campaigns to fight apartheid and bring relief to the world's poorest. You founded We Are the World, which brought together some of the greatest talents in music to draw attention to and take on the scourge of famine in Africa. You have always used your platform to call out injustice and violence and make sure we never stopped believing that a more just, beautiful world was possible. Your voice — your life — has been a beacon of hope, comfort and inspiration to generations."
Belafonte also served on the board of Americans for the Arts (formerly known as the American Council for the Arts) for many years. He has four children — Shari, Adrienne, Gina and David — and three grandchildren — Rachel, Brian and Maria. He lived with his wife photographer Pamela Frank who he had married in 2008.
"The world is a little dimmer today in losing such a legendary entertainer as Harry Belafonte but so much richer for having had such a tireless, lifelong humanitarian and activist for so many years. Rest easy, kind sir, after a job well done," said Michael Weinstein, president of AIDS Healthcare Foundation.
"Belafonte leveraged his considerable and deserved celebrity for a myriad of causes over his lifetime, including the fight against HIV and AIDS. It was both humbling and a privilege for AHF to thank and honor him in person for his lifetime of activism and compassion."
In 2016, AHF honored Belafonte with its Lifetime Achievement Award during its "Keep the Promise" World AIDS Day Concert and March in Hollywood, Calif.
Ever the activist, Belafonte, then 89, joined marchers for a brief but poignant portion of the march down Hollywood Boulevard.
The march commemorated the millions who have died of AIDS while also serving as a reminder to the world that of the then 36.7 million people living with AIDS worldwide, only 17 million had access to lifesaving antiretroviral treatment.
Belafonte received the AHF award during the concert that followed at the Dolby Theater featuring Patti LaBelle, Common and others who also paid tribute to the humanitarian icon.
Harry Belafonte was a barrier-breaking legend who used his platform to lift others up. He lived a good life – transforming the arts while also standing up for civil rights. And he did it all with his signature smile and style. Michelle and I send our love to his wife, kids, and… pic.twitter.com/g77XCr9U5b
— Barack Obama (@BarackObama) April 25, 2023
The White House issued a statement from President Joe Biden on Belafonte's death:
"Jill and I are saddened by the passing of a groundbreaking American who used his talent, his fame, and his voice to help redeem the soul of our nation.
Harry Belafonte was born to Caribbean parents in Harlem, New York on March 1, 1927, when segregation was the order of American society. To our Nation's benefit, Harry never accepted those false narratives and unjust boundaries. He dedicated his entire life to breaking barriers and bridging divides.
As a young man motivated to find his purpose, he became mesmerized by theater when he saw a performance of the American Negro Theater in Manhattan. As one of America's original breakthrough singers and performers, he would go on to garner a storehouse of firsts — the first Black matinee idol, the first recording artist to sell over a million records, the first Black male Broadway actor to win a Tony award, the first Black producer to win an Emmy award, and one of the highest paid entertainers of his time, among other accolades.
But he used his fame and fortune for the public good throughout his extraordinary career. He became a powerful ally of Dr. Martin Luther King, Jr., and other giants of the Civil Rights Movement. He raised money and donated resources to post bail for activists jailed for acts of civil disobedience. He provided the critical funds to launch the Freedom Rides.
He lobbied against apartheid in South Africa, for the release of Nelson Mandela, and was one of the visionaries behind 'We Are the World,' an innovative record released to raise millions of dollars to support humanitarian aid in Sudan and Ethiopia. For these and other humanitarian and artistic efforts he was conferred with a Kennedy Center Honor, the National Medal of the Arts, and a Grammy lifetime achievement award.
Harry Belafonte's accomplishments are legendary and his legacy of outspoken advocacy, compassion, and respect for human dignity will endure. He will be remembered as a great American.
We send our deepest condolences to his family and legions of admirers across the country and the world."

More than 1 million people attend Madonna concert in Rio
Free event took place on Copacabana Beach on Saturday
An estimated 1.6 million people on Saturday attended Madonna's free concert on Rio de Janeiro's Copacabana Beach.
The concert, which was the last one as part of Madonna's Celebration Tour, included a tribute to people lost to AIDS.
Bob the Drag Queen introduced Madonna before the concert began. Pabllo Vittar, a Brazilian drag queen and singer, and Anitta, a bisexual pop star who was born in Rio's Honório Gurgel neighborhood, also joined Madonna on stage.
Congresswoman Erika Hilton, a Black travesti and former sex worker, and Rio Municipal Councilwoman Mônica Benício, the widow of Marielle Franco, a bisexual Rio Municipal Councilwoman who was assassinated in 2018, are among those who attended the concert.
"Madonna showed that we fight important fights for the human rights of Black (people), young (people), women and LGBTQIA+ people, and against all injustice, discrimination, and violence," said Associaçao Nacional de Travestis e Transexuais (National Association of Travestis and Transsexuals), a Brazilian trans rights group known by the acronym ANTRA, on its X account. "What they call identitarianism' is our subversion to the retrograde and conservative tackiness that plagues the country."
The Associated Press reported the concert was Madonna's biggest ever.
In a move aimed at celebrating the beauty, brilliance and resilience of the LGBTQ community, the Human Rights Campaign unveiled the "Queer Renaissance Syllabus" that Beyoncé's "Renaissance" album inspired.
Curated by Justin Calhoun, Leslie Hall and Chauna Lawson of the HRC's Historically Black Colleges and Universities Program, the syllabus includes a variety of academic articles, essays, films and other media rooted in Black queer and feminist studies. Each piece is directly inspired by the tracks on Beyoncé's Billboard 200-topping dance album, "Renaissance."
Beyoncé's album "Renaissance" stands as a cultural milestone, celebrating the Black queer roots of dance music while shedding light on overlooked Black queer artists. Inspired by her late-Uncle Johnny, the album not only garnered critical acclaim but also shed light on the often marginalized contributions of Black queer artists. Winning four Grammys and yielding chart-topping hits like "Break My Soul" and "Cuff It," the album sparked discussions about economic impact and cultural representation.
Amid its success, legislative challenges arose, with Florida and Texas enacting bans on DEI initiatives in public colleges. Recognizing the album's transformative potential, HRC developed the "Queer Renaissance Syllabus" to leverage its impact for education and activism.
Tailored for educators, youth-serving professionals, DEI practitioners, higher education leaders and admirers of Beyoncé's artistry, the syllabus aims to encourage meaningful discussions, enrich lesson plans, and explore innovative ways to honor the vibrancy and significance of LGBTQ individuals and their culture.
With six themes anchoring the syllabus, ranging from "intersectionality and inclusivity" to "social justice and activism," it provides a comprehensive exploration of various facets of LGBTQ experiences and expressions. Fan-favorite tracks from the album are paired with scholarly readings, offering insights into empowerment, self-acceptance and the transformative power of artistic expression. The syllabus also reinforces HRC's efforts to highlight, amplify and re-center Black and queer voices.
By providing links to articles, books, podcasts and interviews, each associated with a song from the album, it celebrates the rich cultural heritage and contributions of the Black queer community.
The concluding section of the syllabus includes Beyoncé's tribute to O'Shea Sibley, a young Black queer person who was murdered in Brooklyn, N.Y., last July while voguing to "Renaissance" songs at a gas station. HRC also includes a statement that condemns hate crimes.

The Influence Of Inflation On Forex Profit Potential – Inflation is an increase in the prices of goods and services. The best-known measure of inflation is the Consumer Price Index (CPI), which measures the percentage change in the price of a basket of goods and services consumed by households (see Definition: Inflation and Its Measurement). The CPI is a measure of inflation used by the Reserve Bank of Australia in its inflation target, where it aims to keep annual consumer price inflation between 2 and 3 percent, on average, over time (see Explainer: Australia's Inflation Target). Other measures of inflation are also analyzed, but most measures of inflation move similarly over the long run.
As their names suggest, "demand-pull inflation" is caused by developments on the demand side of the economy, while "cost-push inflation" is caused by the effects of higher input costs on the supply side of the economy. Inflation can also result from 'inflationary expectations' – that is, what households and businesses think will happen to prices in the future can affect actual prices in the future. These different causes of inflation are taken into account by the Reserve Bank when it analyzes and forecasts inflation.
The Influence Of Inflation On Forex Profit Potential
Demand-pull inflation occurs when the total demand for goods and services (ie, "aggregate demand") increases to exceed the supply of goods and services (ie, "aggregate supply") that can be sustainably produced. Excess demand puts upward pressure on prices for a wide range of goods and services, and ultimately causes inflation to rise – that is, it "raises" inflation.
Inflation Is Back And So Is Momentum Investing
Aggregate demand may increase because spending by consumers, businesses, or the government increases, or because net exports increase. As a result, demand for goods and services will increase relative to their supply, providing firms with the opportunity to raise prices (and their margins—which is their markup over costs). At the same time, firms will try to hire more workers to meet this additional demand. Due to increased demand for labor, firms may have to offer higher wages to attract new employees and retain existing employees. Firms may also raise the prices of their goods and services to cover higher labor costs.
More jobs and higher wages increase household incomes and lead to higher consumer spending, which further increases aggregate demand and firms' ability to raise prices for their goods and services. When this happens in a large number of businesses and sectors, it causes inflation to rise.
The opposite will happen when aggregate demand decreases; Firms with less demand will either stop hiring or lay off staff, meaning less staff are needed. This puts upward pressure on the unemployment rate. More workers looking for work means firms can offer lower wages, putting downward pressure on household incomes, consumer spending, and the prices of their goods and services. As a result, inflation will decrease.
The supply of goods and services that can be sustainably produced is also known as the economy's potential output or full capacity. At this level of output, factors of production such as labor and capital (which includes the machinery and equipment that firms use to produce their goods and services) are used as intensively as possible without causing inflationary pressure. When aggregate demand exceeds the economy's potential output, this will put upward pressure on prices. When aggregate demand is below potential output, this will put downward pressure on prices.
Cryptocurrency And Inflation: Everything You Need To Know
So how can we measure how far the economy is from its potential output (or full capacity) and what this means for inflation? Although we can measure aggregate demand fairly accurately from quarter to quarter using gross domestic product (GDP) data from national accounts (see definition: economic growth), potential output is not directly observable—that is, we must infer it. Other evidence about the behavior of the economy. For example, just as there is a level of output where inflation is stable, there is also a level of unemployment that corresponds to stable inflation. It is known as the non-accelerating inflation rate for unemployment or NAIRU for short (see definition: non-accelerating inflation rate for unemployment (NAIRU)). When unemployment is below the NAIRU, inflation will increase and when it is above the NAIRU, inflation will decrease.
Budget inflation occurs when the total supply of goods and services that can be produced in an economy (aggregate supply) falls. A drop in total supply is often caused by an increase in the cost of production. If aggregate supply falls but aggregate demand remains the same, pressure is put on prices and inflation—that is, inflation is higher.
An increase in the price of domestic or imported products (such as oil or raw materials) increases production costs. As firms face higher costs of producing each unit of output, they tend to produce lower levels of output and raise the prices of their goods and services. This can affect other goods and services by increasing their prices. For example, an increase in the price of oil, which is the main income in many sectors of the economy, will initially lead to an increase in the price of gasoline. However, higher gasoline prices will also make it more expensive to transport goods from one place to another, which in turn will drive up prices for things like groceries.
Cost-related inflation can also occur due to supply disruptions in specific industries – for example, due to unusual weather or natural disasters. Large cyclones and floods occur periodically, damaging large amounts of agricultural produce and causing significant increases in processed food and both food and restaurant prices, leading to temporary periods of higher inflation.
How Food And Energy Are Driving The Global Inflation Surge
Exchange rate movements can also affect prices and affect inflation outcomes. A decrease in the value of the domestic currency – or depreciation – will increase inflation in two ways. First, the prices of goods and services produced abroad increase compared to those produced in the country. Consequently, consumers pay more to buy the same imported products, and firms that rely on imported materials in their production processes pay more to buy those products. Rising prices of imported goods and services directly contribute to inflation through the channel of rising costs.
Second, currency depreciation stimulates aggregate demand. This happens because exports become relatively cheap for foreigners, leading to an increase in demand for exports and an increase in aggregate demand. At the same time, domestic consumers and firms reduce their consumption of relatively more expensive imports and buy more domestically produced goods and services, which again leads to an increase in aggregate demand. This increase in aggregate demand puts pressure on domestic production capacity and increases the opportunity for domestic firms to raise prices. These price increases indirectly contribute to inflation through the demand pull channel.
In terms of imported inflation, the exchange rate has a greater impact on inflation through its impact on exports and the prices of imported goods and services (known as tradable goods and services), while the prices of non-tradable goods and services are more dependent. on internal events.
Inflationary expectations are the beliefs that households and firms have about future price increases. They are important because expectations of future price increases can influence current economic decisions, which can affect actual inflation outcomes. For example, if firms expect future inflation to be higher and act on these beliefs, they may raise the prices of their goods and services at a faster rate. Similarly, if workers expect future inflation to be higher, they may demand higher wages to compensate for the expected loss of purchasing power. This behavior, sometimes called the "psychology of inflation," can contribute to a higher rate of actual inflation so that inflation expectations become self-fulfilling.
Effects Of Inflation On Business: The Good And The Bad
Given that inflationary expectations can affect real prices and wages, the degree to which inflationary expectations are "hardened" affects future inflation outcomes. For example, if households and firms expect inflation to return to the central bank's inflation target at some point in the future, regardless of what current inflation is, we describe their expectations as the inflation target. When expectations are firm, a period of higher inflation—perhaps driven by rising spending—will not cause households and firms to change their behavior, and as a result, inflation is likely to eventually return to its target. But if the inflation psychology of households and firms changes and inflation expectations move towards the central bank's inflation target (i.e. the future and adjust their behavior accordingly. Therefore, it is much easier for the central bank to manage inflation if inflation expectations are anchored and not unfounded.
Long-term inflation expectations remain little changed in response to periods of high inflation. Households and firms expect the increase in inflation to be temporary and will not change

Throughout the environment now, a single in seven persons is malnourished and enduring the results of a problem which is anticipated to worsen as the global populace proceeds to increase. If we are to maintain our all-natural biodiversity and habitat we are not able to carry on to extend arable lands.
Moreover, not all land is acceptable for escalating crops. This means that we will have to discover new means to increase the productiveness of foodstuff crops within the current area offered and in a extensive selection of disorders, which includes the escalating affect of local weather alter.
The EU-funded FUTUREAGRICULTURE project is working on a radically distinct technique centred all around the approach of photorespiration. Normal plant photorespiration requires up oxygen in the mild, dissipates vitality made by photosynthesis and releases carbon dioxide (CO2) again into the ambiance. This minimizes the effective rate of carbon fixation and thereby lowers agricultural productiveness.
By building and engineering vegetation that can get over the deficiencies of all-natural photorespiration, FUTUREAGRICULTURE aims to increase agricultural produce.
One of the principal barriers to increasing produce is the minimal performance of carbon fixation the approach by means of which lifestyle vitality is converted into biomass or sugars. We determined to target on this approach, noting recent inefficiencies and also where by intervention may be doable, claims project coordinator Dr Arren Bar-Even of the Max Planck Institute in Germany.
Building novel enzymes
Making use of condition-of-the-art synthetic biology tools, the project workforce established out to style and design and engineer solely new CO2-neutral or CO2-constructive photorespiration pathways based mostly on novel enzyme chemistry. Making use of laptop or computer simulations, their perform demonstrated that specified bypass routes could radically increase the agricultural productiveness rate possibly by as substantially as 60 %, and would also be ready support higher yields in a extensive variety of disorders, this sort of as drought, weak mild, and so forth.
We located 5 or six pathways which appeared to be really interesting and incorporated acknowledged enzymes. But we also learned new enzymes not nonetheless acknowledged to nature but which we have been ready to engineer, explains Bar-Even.
In-vitro study is now ongoing to establish the capabilities of these novel enzymes and pathways in dwelling organisms. Enhanced photosynthetic performance will be demonstrated in vivo in cyanobacteria (photosynthetic microbes dwelling in the soil and drinking water) expressing the synthetic pathways. Last but not least, the most promising pathways will be executed in product vegetation and the expansion phenotypes will be monitored.
These new pathways are also anticipated to execute really effectively underneath complicated or tough disorders due to the fact they are substantially additional CO2 efficient. We be expecting the vegetation to be additional tolerant to the lack of drinking water and they should really be ready to make additional biomass per device of land and of time than at present.
FUTUREAGRICULTURE represents a radical breakthrough in study to increase agricultural productiveness by systematically exploring new metabolic pathways previously mysterious in nature which have a substantial likely to revolutionise the way vegetation improve. |
The Environment
We are all concerned about the environment, we can all learn to look after the world better than we have done. but we in the UK are not all to blame for something that many in the past have called progress.
We are concerned about net zero agenda and the impact that it is having on the standard of living for many people around the world.
To tackle so called climate change and its negative impacts, world leaders on 12th December 2015 agreed to the Paris Agreement.
What is the Paris agreement?
It's a climate change accord agreed by nearly 200 countries in December 2015, which came into force on 4 November 2016. The agreement commits world leaders to keeping global warming below 2C, seen as the threshold for safety by scientists, and pursuing a tougher target of 1.5C. The carbon emission curbs put forward by countries under Paris are not legally-binding but the framework of the accord, which includes a mechanism for periodically cranking those pledges up, is binding. The agreement also has a long-term goal for net zero emissions which would effectively phase out fossil fuels.
The Agreement is a legally binding international treaty. It entered into force on 4 November 2016.
The Agreement includes commitments from all countries to reduce their emissions and work together to adapt to the impacts of climate change, and calls on countries to strengthen their commitments over time. The Agreement provides a pathway for developed nations to assist developing nations in their climate mitigation and adaptation efforts while creating a framework for the transparent monitoring and reporting of countries' climate goals.
This sounds like a control and punishment mechanism to me and I believe the United Kingdom must withdraw from this agreement.
Let's celebrate our success so far, as the UK has led the way by reducing our emissions since 1990 by about 50%. Technology improvements will enable us to reduce emissions further and capture emissions. However, we must be smart about which technologies to use.
The Reform UK triple save plan will:
• save emissions
• save and create British jobs
• save households money
We must maintain a range of types of energy supply, so we are not overexposed to any one particular supply; prices, technology, and relative performance will vary over time. We will boost the solar and wind renewable sector using a new government-owned Renewable Bank; the panels and turbines must be made here in the UK to save and create British jobs. This will also mean dramatically lower utility costs.
The current Government plans will destroy British jobs, sending them overseas especially to China, and lead to huge increases in domestic bills every year to pay to overseas-owned energy firms. This is both unacceptable and unnecessary.
This too-speedy a transition to renewable energy has driving the current energy market crisis, and the cost of implementing net zero policies will be far too costly on the poorest in our society
While our Government commits hari kari on the UK economy and creates laws and regulations to tie up business in the name of a so called climate change agenda, China is the world's largest emitter of greenhouse gases with a reliance on coal for energy, The Chinese government has set a 2060 Net Zero emissions target…
C40 CITIES – https://c40summit.org/
With Government forcing companies how to adhere to the net zero agenda or be punished, it is now the C40 groups turn to control the public in the area's they live.
In my opinion, this is just another mechanism of control for the people to do as we say. or you will be punished using the lockdown laws currently in place from the so called pandemic.
The Race to Zero is a global campaign to rally leadership and support from businesses, cities, regions, and investors for a healthy, resilient, zero carbon recovery that prevents future threats, creates decent jobs, and unlocks inclusive, sustainable growth.
from the website:-
"Ours is a vision of climate action that is rooted in equity, because we know that climate, social and economic justice can only be achieved together"
It looks like 2023 in going to be a year of massive change in this country towards the climate agenda and the green new deal – We will just have to wait and see how things play out.
The leadership standards guide below.
55 Councils & Towns across the England, 7 more in Scotland & NI have signed up to this C40 agenda that includes 15 minute cities, those involved have agreed to the below and more –
Publicly endorse the following Principles:
We recognise the global climate emergency.
We are committed to keeping global heating below the 1.5°Celsius goal of the Paris Agreement.
We are committed to putting inclusive climate action at the center of all urban decision-making, to create thriving and equitable communities for everyone.
We invite our partners – political leaders, CEOs, trade unions, investors, and civil society – to join us in recognising the global climate emergency and help us deliver on science-based action to overcome it. |
The Timeless Elegance of 1940s and 1950s Fashion
A Brief History Lesson in Glamour
To understand the pull of vintage fashion, we must first glance back at the societal tapestry that birthed these iconic styles. The era following World War II was defined by a particular poignancy that translated into the silhouettes and fabrics of the time. The 1940s marked an era of utilitarian fashion, where fabric rationing led to a more pragmatic yet elegant silhouette for both men and women. From pencil skirts and tailored suits to peplum accents, fashion became an art of making do and making beautiful. Post-war, the 1950s saw a resurgence of opulent designs, with Dior's 'New Look' debuting in 1947, steering fashion towards a more lavish aesthetic. Cinched waistlines, full skirts, and lace were the epitome of femininity, while for men, sharp cuts and high rise trousers exuded a sophisticated masculinity.
Iconic Looks and Their Influence
In the 1940s, women's fashion was all about strength and suave. The noble spirit of the war reflected in military-inspired trench coats, strong shoulders, and the ubiquitous snood, which became synonymous with the Rosie the Riveter spirit. Moving into the 1950s, women's fashion bloomed with the idea of unapologetic femininity. We saw the birth of the sweater girl look, characterized by tight-fitting jumpers, and the rockabilly aesthetic which gave the world the timeless appeal of jeans and t-shirts. On the other hand, men's fashion in the post-war years was a lesson in refinement. Tailored suits, fedoras, and the enduring popularity of the trench coat bespoke a sense of timeless charm woven into the fabric of every ensemble.
The Revival of Vintage in Modern Trends
The past decade has seen a considerable upsurge in the appreciation of vintage fashion. Designers and fashionistas alike continue to draw inspiration from the 1940s and 1950s, infusing their collections with a dash of nostalgia. From the runways of Paris to the streets of Tokyo, vintage styles can be spotted in the most contemporary of outfits. The 1940s-1950s serve as a reference point for those seeking to make a statement that is at once elegant and bold.
Tips for Seamlessly Blending Vintage into Your Wardrobe
The beauty of vintage fashion is its adaptability. It can be the focal point of your ensemble or a subtle accessory that anchors your look in time. For the ladies, a 1950s scarf or a pair of 1940s pumps can add that touch of old-school chic to a modern outfit. Gentlemen can opt for a classic fedora or a subtly patterned tie to give their attire a vintage twist. Balance is key when incorporating vintage pieces; pair them with modern cuts and fabrics to achieve a harmonious ensemble that speaks to both the past and present.
Sustainable Style: The Value of Vintage
An often uncelebrated aspect of vintage fashion is its sustainable nature. By choosing pre-loved clothing, you are not only nurturing a unique sense of style but also contributing to a more eco-conscious world. The fashion industry is one of the largest contributors to environmental degradation, and by favoring vintage, you participate in the reduction of waste and carbon footprint.
Where to Find Your Piece of History
The thrill of the hunt is as much a part of vintage fashion as the pieces themselves. Scour local thrift shops, flea markets, and vintage boutiques for that one-of-a-kind garment that speaks to your soul. Online platforms have also become invaluable resources, connecting enthusiasts with sellers from around the globe. Whether it's a full ensemble or a single accessory, the joy of discovery is unparalleled.
Concluding Thoughts on Timeless Treasures
Vintage fashion is not merely a trip down memory lane; it is a celebration of individuality, style, and sustainability. It allows us to be part of a narrative that transcends time, and in doing so, we become both interpreters and guardians of our cultural and sartorial heritage. In a world where trends come and go, the elegance of the 1940s and 1950s stands as a testament to the fact that true style is eternal.
Join the Vintage Conversation
We invite you to share your love for all things vintage. Tell us about your most treasured piece from the 1940s-1950s or your favorite way to incorporate vintage into your daily style.

1-in-5 Gen Z workers haven't spoken to colleagues over 50 in a year.
There are notable differences between the younger generation and previous generations, such as our parents and grandparents.
Gen Z is often characterised as demanding, opinionated, and outspoken. They are also seen as the generation most likely to hold their employers accountable for their promises.
The distinctiveness of Gen Z has been both celebrated and criticised, largely due to a misunderstanding of their behaviour, particularly by older employees.
This divide is exemplified by a recent LinkedIn study, which found that one in five Gen Z employees have not spoken to a colleague over the age of 50 in the past year. Conversely, 40% of those over 55 have not had conversations with Gen Z colleagues during the same period.
This disconnect poses a growing issue in the workplace, particularly in intergenerational companies, where staff members from different age groups, with varying concerns and experiences, struggle to communicate with one another and, as a result, tend to avoid interactions.
This situation is detrimental to businesses, and employers must find ways to effectively integrate their staff within a diverse company. The research suggests that although Gen Z employees are confident in expressing their thoughts and feelings to their managers, they do not always feel comfortable communicating with more experienced colleagues.
Another report indicates that one of the main reasons for this is that younger workers feel they lack common ground with older colleagues due to differences in personal life stages, such as not having pets, spouses, or children.
However, without intergenerational communication, innovation, growth, and a healthy work culture are compromised. To foster an environment that encourages such communication, employers should respect the differences between generations while creating opportunities for people to engage in ways that they feel comfortable with.
Research shows that face-to-face communication is valued by all generations, so providing opportunities for in-person meetings can facilitate more informal points of contact.
Gen Z also prioritises personal development in the workplace. Employers can leverage the experience of older workers by creating mentoring programs that allow young people to fulfil their desire to learn while simultaneously building stronger intergenerational bonds.
Being aware that younger employees may feel disconnected from their older colleagues should motivate employers to create spaces for meaningful communication. Ultimately, the quality of these relationships reflects the quality of the business itself. |
NGC 891: A Close-Up Look at the Silver Sliver Galaxy
NGC 891, also known as the Silver Sliver Galaxy, has long been a subject of fascination for astronomers. With its edge-on orientation and similarity to our own Milky Way, it presents a wealth of mysteries waiting to be unraveled.
In this article, we'll take a close-up look at NGC 891 and answer some questions you may have about this enigmatic celestial body.
Where is NGC 891 located?
NGC 891 is a galaxy located in the constellation of Andromeda, about 30 million light-years away from Earth. It is a member of the NGC 1023 group of galaxies in the Local Supercluster.
What type of galaxy is NGC 891?
NGC 891 is an edge-on unbarred spiral galaxy. This type of galaxy lacks a central bar like the one in our own Milky Way galaxy.
How big is NGC 891?
Its disk is approximately 100,000 light-years in diameter and contains a prominent dust lane that runs along its midplane. The galaxy also has a prominent central bulge and a halo of stars that extends far beyond its disk.
Why is NGC 891 known as the Silver Sliver Galaxy?
This unique galaxy is often referred to as the Silver Sliver Galaxy due to its thin, elongated shape from our vantage point. NGC 891 is a popular target for astronomers due to its edge-on orientation, which gives us a rare opportunity to study its structure and contents.
Why is NGC 891 also known as the Outer Limits Galaxy?
NGC 891 is sometimes called the Outer Limits Galaxy because it appeared in the end credits of the famous Outer Limits TV show alongside the Andromeda Galaxy, M67, the Sombrero Galaxy, the Pinwheel Galaxy, NGC 5128, NGC 1300, and M81. This TV show brought some recognition to this galaxy in popular culture.
Despite its relative proximity, there is still much we don't know about NGC 891, and astronomers continue to study this fascinating galaxy to unravel its mysteries. |
What is chemex? Chemex is one of the most popular third-generation coffee brewing tools that can provide an ideal taste of a brewed coffee in any situation. This tool was invented by Peter Shelboom in 1941, which was gradually mass-produced by Chemex in Massachusetts, so that even as one of the best inventions in 1958, an example of it was placed in the art museum. The method of brewing by chemex is the same in electric models and manual models, in this way, it is done by pouring water on the coffee powder.
How to prepare coffee with chemex, the essentials required for this brewing method are a scale, chemex, filter (chemex) and kettle (kettle). At first, you should grind your coffee beans to the right degree for chemex. The amount of coffee needed for brewing Avari for two people is 27 grams. Preferably, if the coffee is ground before brewing, it has a significant effect on the final flavor. The water used is also measured by the main ratio of grams of coffee per liter of water (55 to 65 grams of coffee per liter of water), according to this ratio, we need 450 cc of water for this brewing. Then put the filter in the opening of the filter. Also, in the type of placement, it should be noted that the three-leaf part of the filter should be placed in front of the filter.
In the next step, use a kettle to pour boiling water on all parts of the filter until it is completely wet. This work is done for three reasons: firstly, the taste of the paper filter is lost, secondly, the container compartment is completely heated, and thirdly, the filter sticks to the container completely. After this, empty the water inside the coffee maker and place it on the scale and empty your ground coffee on the filter. In the next step, pour water with a temperature between 92 and 96 degrees Celsius (water that has boiled) to the amount of 2 times the weight of the coffee (here about 50 grams) on the surface of the coffee. At this stage, with the release of carbon dioxide gases, bubbles are formed on the surface of the coffee, which is called blooming. Empty the rest of the water evenly over the coffee, but the only point of this part is that the water from the The surface of the coffee should not be separated. At the end, you can stir the surface of the water with a wooden spoon for better extraction.
Enjoy your meal!

Current methods of identifying the ionizing source of nebular emission in galaxies are well defined for the era of single-fiber spectroscopy, but still struggle to differentiate the complex and overlapping ionization sources in some galaxies. With the advent of integral field spectroscopy, the limits of these previous classification schemes are more apparent. We propose a new method for distinguishing the ionizing source in resolved galaxy spectra by use of a multidimensional diagnostic diagram that compares emission-line ratios with velocity dispersion on a spaxel-by-spaxel basis within a galaxy. This new method is tested using the Sydney-Australian-Astronomical-Observatory Multi-object Integral-Field Spectrograph Galaxy Survey (SAMI) Data Release 3 (DR3), which contains 3068 galaxies at

Abstract z < 0.12. Our results are released as ionization maps available alongside the SAMI DR3 public data. Our method accounts for a more diverse range of ionization sources than the standard suite of emission-line diagnostics; we find 1433 galaxies with a significant contribution from non-star-forming ionization using our improved method as compared to 316 galaxies identified using only emission-line ratio diagnostics. Within these galaxies, we further identify 886 galaxies hosting unique signatures inconsistent with standard ionization by Hii regions, active galactic nuclei, or shocks. These galaxies span a wide range of masses and morphological types and comprise a sizable portion of the galaxies used in our sample. With our revised method, we show that emission-line diagnostics alone do not adequately differentiate the multiple ways to ionize gas within a galaxy. -
ABSTRACT We study the alignments of galaxy spin axes with respect to cosmic web filaments as a function of various properties of the galaxies and their constituent bulges and discs. We exploit the SAMI Galaxy Survey to identify 3D spin axes from spatially resolved stellar kinematics and to decompose the galaxy into the kinematic bulge and disc components. The GAMA survey is used to reconstruct the cosmic filaments. The mass of the bulge, defined as the product of stellar mass and bulge-to-total flux ratio Mbulge = M⋆ × (B/T), is the primary parameter of correlation with spin–filament alignments: galaxies with lower bulge masses tend to have their spins parallel to the closest filament, while galaxies with higher bulge masses are more perpendicularly aligned. M⋆ and B/T separately show correlations, but they do not fully unravel spin–filament alignments. Other galaxy properties, such as visual morphology, stellar age, star formation activity, kinematic parameters, and local environment, are secondary tracers. Focussing on S0 galaxies, we find preferentially perpendicular alignments, with the signal dominated by high-mass S0 galaxies. Studying bulge and disc spin–filament alignments separately reveals additional information about the formation pathways of the corresponding galaxies: bulges tend to have more perpendicular alignments, while discs show different tendencies according to their kinematic features and the mass of the associated bulge. The observed correlation between the flipping of spin–filament alignments and the growth of the bulge can be explained by mergers, which drive both alignment flips and bulge formation.
ABSTRACT We present SAMI-H i, a survey of the atomic hydrogen content of 296 galaxies with integral field spectroscopy available from the SAMI Galaxy Survey. The sample spans nearly 4 dex in stellar mass ($M_\star = 10^{7.4}-10^{11.1}~ \rm M_\odot$), redshift z < 0.06, and includes new Arecibo observations of 153 galaxies, for which we release catalogues and H i spectra. We use these data to compare the rotational velocities obtained from optical and radio observations and to show how systematic differences affect the slope and scatter of the stellar-mass and baryonic Tully–Fisher relations. Specifically, we show that $\rm H\alpha$ rotational velocities measured in the inner parts of galaxies (1.3 effective radii in this work) systematically underestimate H i global measurements, with H i/$\rm H\alpha$ velocity ratios that increase at low stellar masses, where rotation curves are typically still rising and $\rm H\alpha$ measurements do not reach their plateau. As a result, the $\rm H\alpha$ stellar mass Tully–Fisher relation is steeper (when M⋆ is the independent variable) and has larger scatter than its H i counterpart. Interestingly, we confirm the presence of a small fraction of low-mass outliers of the $\rm H\alpha$ relation that are not present when H i velocity widths are used and are not explained by 'aperture effects'. These appear to be highly disturbed systems for which $\rm H\alpha$ widths do not provide a reliable estimate of the rotational velocity. Our analysis reaffirms the importance of taking into account differences in velocity definitions as well as tracers used when interpreting offsets from the Tully–Fisher relation, at both low and high redshifts and when comparing with simulations.
ABSTRACT Using data from the SAMI Galaxy Survey, we investigate the correlation between the projected stellar kinematic spin vector of 1397 SAMI galaxies and the line-of-sight motion of their neighbouring galaxies. We calculate the luminosity-weighted mean velocity difference between SAMI galaxies and their neighbours in the direction perpendicular to the SAMI galaxies' angular momentum axes. The luminosity-weighted mean velocity offset between SAMI galaxies and neighbours, which indicates the signal of coherence between the rotation of the SAMI galaxies and the motion of neighbours, is 9.0 ± 5.4 km s−1 (1.7σ) for neighbours within 1 Mpc. In a large-scale analysis, we find that the average velocity offsets increase for neighbours out to 2 Mpc. However, the velocities are consistent with zero or negative for neighbours outside 3 Mpc. The negative signals for neighbours at a distance around 10 Mpc are also significant at the ∼2σ level, which indicate that the positive signals within 2 Mpc might come from the variance of large-scale structure. We also calculate average velocities of different subsamples, including galaxies in different regions of the sky, galaxies with different stellar masses, galaxy type, λRe, and inclination. Although subsamples of low-mass, high-mass, early-type, and low-spin galaxies show the 2–3σ signal of coherence for the neighbours within 2 Mpc, the results for different inclination subsamples and large-scale results suggest that the ∼2σ signals might result from coincidental scatter or variance of large-scale structure. Overall, the modest evidence of coherence signals for neighbouring galaxies within 2 Mpc needs to be confirmed by larger samples of observations and simulation studies.
ABSTRACT We study environmental quenching using the spatial distribution of current star formation and stellar population ages with the full SAMI Galaxy Survey. By using a star formation concentration index [C-index, defined as log10(r50, H α/r50, cont)], we separate our sample into regular galaxies (C-index ≥−0.2) and galaxies with centrally concentrated star formation (SF-concentrated; C-index <−0.2). Concentrated star formation is a potential indicator of galaxies currently undergoing 'outside-in' quenching. Our environments cover ungrouped galaxies, low-mass groups (M200 ≤ 1012.5M⊙), high-mass groups (M200 in the range 1012.5–14 M⊙) and clusters (M200 > 1014M⊙). We find the fraction of SF-concentrated galaxies increases as halo mass increases by 9 ± 2 per cent, 8 ± 3 per cent, 19 ± 4 per cent, and 29 ± 4 per cent for ungrouped galaxies, low-mass groups, high-mass groups, and clusters, respectively. We interpret these results as evidence for 'outside-in' quenching in groups and clusters. To investigate the quenching time-scale in SF-concentrated galaxies, we calculate light-weighted age (AgeL) and mass-weighted age (AgeM) using full spectral fitting, as well as the Dn4000 and HδA indices. We assume that the average galaxy age radial profile before entering a group or cluster is similar to ungrouped regular galaxies. At large radius (1–2 Re), SF-concentrated galaxies in high-mass groups have older ages than ungrouped regular galaxies with an age difference of 1.83 ± 0.38 Gyr for AgeL and 1.34 ± 0.56 Gyr for AgeM. This suggests that while 'outside-in' quenching can be effective in groups, the process will not quickly quench the entire galaxy. In contrast, the ages at 1–2 Re of cluster SF-concentrated galaxies and ungrouped regular galaxies are consistent (difference of 0.19 ± 0.21 Gyr for AgeL, 0.40 ± 0.61 Gyr for AgeM), suggesting the quenching process must be rapid.
ABSTRACT The kinematic morphology–density relation of galaxies is normally attributed to a changing distribution of galaxy stellar masses with the local environment. However, earlier studies were largely focused on slow rotators; the dynamical properties of the overall population in relation to environment have received less attention. We use the SAMI Galaxy Survey to investigate the dynamical properties of ∼1800 early and late-type galaxies with log (M⋆/M⊙) > 9.5 as a function of mean environmental overdensity (Σ5) and their rank within a group or cluster. By classifying galaxies into fast and slow rotators, at fixed stellar mass above log (M⋆/M⊙) > 10.5, we detect a higher fraction (∼3.4σ) of slow rotators for group and cluster centrals and satellites as compared to isolated-central galaxies. We find similar results when using Σ5 as a tracer for environment. Focusing on the fast-rotator population, we also detect a significant correlation between galaxy kinematics and their stellar mass as well as the environment they are in. Specifically, by using inclination-corrected or intrinsic $\lambda _{R_{\rm {e}}}$ values, we find that, at fixed mass, satellite galaxies on average have the lowest $\lambda _{\, R_{\rm {e}},\rm {intr}}$, isolated-central galaxies have the highest $\lambda _{\, R_{\rm {e}},\rm {intr}}$, and group and cluster centrals lie in between. Similarly, galaxies in high-density environments have lower mean $\lambda _{\, R_{\rm {e}},\rm {intr}}$ values as compared to galaxies at low environmental density. However, at fixed Σ5, the mean $\lambda _{\, R_{\rm {e}},\rm {intr}}$ differences for low and high-mass galaxies are of similar magnitude as when varying Σ5 ($\Delta \lambda _{\, R_{\rm {e}},\rm {intr}} \sim 0.05$, with σrandom = 0.025, and σsyst < 0.03). Our results demonstrate that after stellar mass, environment plays a significant role in the creation of slow rotators, while for fast rotators we also detect an independent, albeit smaller, impact of mass and environment on their kinematic properties.more » « less
null (Ed.)ABSTRACT We measure the gas-phase metallicity gradients of 248 galaxies selected from Data Release 2 of the SAMI Galaxy Survey. We demonstrate that there are large systematic discrepancies between the metallicity gradients derived using common strong emission line metallicity diagnostics. We determine which pairs of diagnostics have Spearman's rank coefficients greater than 0.6 and provide linear conversions to allow the accurate comparison of metallicity gradients derived using different strong emission line diagnostics. For galaxies within the mass range 8.5 < log (M/M⊙) < 11.0, we find discrepancies of up to 0.11 dex/Re between seven popular diagnostics in the metallicity gradient–mass relation. We find a suggestion of a break in the metallicity gradient–mass relation, where the slope shifts from negative to positive, occurs between 9.5 < log (M/M⊙) < 10.5 for the seven chosen diagnostics. Applying our conversions to the metallicity gradient–mass relation, we reduce the maximum dispersion from 0.11 dex/Re to 0.02 dex/Re. These conversions provide the most accurate method of converting metallicity gradients when key emission lines are unavailable. We find that diagnostics that share common sets of emission line ratios agree best, and that diagnostics calibrated through the electron temperature provide more consistent results compared to those calibrated through photoionization models.more » « less
null (Ed.)ABSTRACT It has been proposed that S0 galaxies are either fading spirals or the result of galaxy mergers. The relative contribution of each pathway and the environments in which they occur remain unknown. Here, we investigate stellar and gas kinematics of 219 S0s in the SAMI Survey to look for signs of multiple formation pathways occurring across the full range of environments. We identify a large range of rotational support in their stellar kinematics, which correspond to ranges in their physical structure. We find that pressure-supported S0s with v/σ below 0.5 tend to be more compact and feature misaligned stellar and gas components, suggesting an external origin for their gas. We postulate that these S0s are consistent with being formed through a merger process. Meanwhile, comparisons of ellipticity, stellar mass, and Sérsic index distributions with spiral galaxies show that the rotationally supported S0s with v/σ above 0.5 are more consistent with a faded spiral origin. In addition, a simulated merger pathway involving a compact elliptical and gas-rich satellite results in an S0 that lies within the pressure-supported group. We conclude that two S0 formation pathways are active, with mergers dominating in isolated galaxies and small groups, and the faded spiral pathway being most prominent in large groups ($10^{13}\lt \rm {M_{halo}}\lt 10^{14}$).more » « less
ABSTRACT We have entered a new era where integral-field spectroscopic surveys of galaxies are sufficiently large to adequately sample large-scale structure over a cosmologically significant volume. This was the primary design goal of the SAMI Galaxy Survey. Here, in Data Release 3, we release data for the full sample of 3068 unique galaxies observed. This includes the SAMI cluster sample of 888 unique galaxies for the first time. For each galaxy, there are two primary spectral cubes covering the blue (370–570 nm) and red (630–740 nm) optical wavelength ranges at spectral resolving power of R = 1808 and 4304, respectively. For each primary cube, we also provide three spatially binned spectral cubes and a set of standardized aperture spectra. For each galaxy, we include complete 2D maps from parametrized fitting to the emission-line and absorption-line spectral data. These maps provide information on the gas ionization and kinematics, stellar kinematics and populations, and more. All data are available online through Australian Astronomical Optics Data Central.more » « less |
How will world commerce be impacted by Red Sea avoidance? – DW – 12/19/2023 | EUROtoday
Over the previous week, many of the world's largest transport corporations have mentioned they may keep away from the Red Sea and subsequently the Suez Canal after Yemen-based Houthi rebels fired missiles at cargo ships over the Israel-Hamas battle.
Instead, ships touring from the Far East to Europe will want to make a detour across the total African continent, by way of South Africa's Cape of Good Hope. The journey will take greater than per week longer and can add about 3,500 nautical miles (6,482 kilometers) to the journey.
The Suez Canal, which connects the Red Sea to the Mediterranean, is the shortest route between Europe and Asia. About 12% of worldwide transport site visitors usually transits the waterway.
Costs for transport corporations skyrocket
The determination is already having a huge effect on the price of transport items, say trade analysts. If it turns into an prolonged disaster, it might spark a hike within the value customers pay for imported items.
"Take one round-trip voyage from Shanghai to Rotterdam and you add a million dollars in terms of fuel costs from rerouting via the Cape of Good Hop," Peter Sand, chief analyst on the Copenhagen-based market analytics agency Xeneta, informed DW. "So that alone is a huge bill."
Insurance premiums have soared in response to the assaults, whereas container transport traces that run weekly providers between Asia and Europe might want to consider the price of three additional ships to make sure an identical degree of service, Sand added.
The delays in transport will then have knock-on results at container ports throughout Europe, that are normally extraordinarily environment friendly at dealing with flows of massive numbers of containers.
"Let's say I have a port that handles 50,000 containers per week. But then if nothing arrives for a week, and the following week a hundred thousand containers arrive, that can cause congestion problems," Lars Jenson, CEO of Vespucci Maritime, a Denmark-based transport trade consultancy, informed DW.
The Red Sea disaster has stirred recollections of March 2021 when the Suez Canal was blocked for six days after the container ship Ever Given ran aground. At that second, the world was exiting lockdowns from the COVID-19 pandemic and large bottlenecks had already emerged in world commerce provide chains.
Hundreds of ships have been left in a holding sample within the Red Sea for weeks and the price of transport a container rose from $2,000 (€1,828) to $14,000. The Ever Given disaster precipitated months of further delays to items imported from Asia.
Supply chains extra strong at this time
Although provide chains have since largely returned to regular, the safety risk within the Red Sea might see costs double over the subsequent few weeks, say analysts. Global freight charges have been already rising once more after the Panama Canal final month curbed the variety of vessels that might ply the waterway that connects the Atlantic and Pacific oceans because of a drought.
Fortunately, the transport trade has discovered the teachings from the post-COVID provide chain disaster and plenty of corporations have expanded their fleet of cargo vessels, that means the impression of any lasting Red Sea rerouting will not be as disastrous.
"Right now we have now an overcapacity of container vessels, so within the absolute worst case, the place we have now to proceed to go round Africa for a time, we do have the container vessels on this planet to do that," Jensen mentioned.
For the primary few days of the present disaster, transport corporations had saved their vessels in a holding sample within the hope that the assaults could be curtailed or safety within the area could be rapidly elevated.
"This week, more and more vessels are being redirected to go around Africa, which seems to indicate the carriers are beginning to lose faith that this crisis can be resolved very rapidly," Jensen added.
US, allies step up naval safety
On Tuesday, the United States introduced a multi-nation operation to safeguard maritime commerce within the Red Sea. As a part of the measure, Britain, Bahrain, Canada, France, Italy, the Netherlands, Norway, Seychelles and Spain will stage joint patrols within the southern Red Sea and the Gulf of Aden.
US and British warships within the space have begun capturing down Houthi missiles and drones in current days. However, it's unclear whether or not the presence of a bigger naval pressure will probably be sufficient to halt the assaults altogether.
Some ships are, nonetheless, persevering with to ply the Red Sea, albeit with armed guards on board, in case their vessels are boarded by Houthi rebels, who insisted Tuesday that the US-led safety operation wouldn't deter them.
"[With Ever Given] it was straightforward to see that it will quickly be resolved. This is extra tough as a result of what's it going to take to get the Houthis to cease launching missiles and drones on the ships, particularly as they're drawing consideration to the [Israel-Hamas] battle?" Jensen informed DW.
Shipment delays will not have an effect on Christmas purchasing, however there's the potential for shops to run low on inventory by February if the delays proceed, provide chain analysis agency Project44 mentioned in a word on Tuesday.
Other analysts have warned that whereas container transport could also be hit more durable general, the delay to vessels carrying fossil fuels to Europe could also be felt first.
"We see energy shipments being impacted right here, right now — whether that's oil or coal or gas — simply due to winter in the northern hemisphere," Sand informed DW. This might result in a knock-on impact on power costs.

Dead people tend to be glorified AND exaggerated after they pass. It happens to the best of the Lord's weak vessels of humanity. Dr. King is no different.
Martin grew up in humble beginnings. Born in Atlanta, Georgia. His father left their family's sharecropper farm to become a minister of the Gospel. After King Sr. married Alberta, they were blessed with three children, Dr. King being the middle child. One of his father's first commissions was the Associate Pastor position at Ebenezer church. After the death of the Senior Pastor, King Senior took the role of head of the church. Thus, Dr. King grew up as a typical "preachers-kid."
As the norm for child discipline in those days, Dr. King grew up with strong parental discipline. However, it was his grandmother that would tell lively Biblical stories to the children. King was close to his grandmother. So much so, once, when his grandmother was knocked unconscious, thinking she was dead, he attempted suicide by jumping from a second-story window. While his attempt was fruitless, his devotion to his grandmother grew more intense after realizing she was not dead. However, it needs to be noted that King suffered "depression" throughout his life, even up to his death.
Like many leaders who suffer from despair, King turned these dark times into fighting for life, not only for himself but those around him. He believed that despair is birth out of bondage to darkness. He further believed that darkness was birthed through slavery – of any type.
Dr. King's passion for equality began with a friendship with a "white boy" who lived across the street from their home. At the early age of six, he was troubled that his friend was attending an all-white school while King was required to attend a "black" school. Soon, his friend's parents stopped allowing King to play with their son. During this time, King's parents educated him on his family's history of slavery and racism. Early on, King stated, "I will determine to hate every white person." Accounts reveal that it took relentless training by his parents to cement the doctrines of, "Son, it is your Christian duty to love everyone." Honestly, as in the case of most great leaders, it was King's parents who were the real heroes in this story.
Through childhood, King watched his father stand up to oppressors of segregation and discrimination while respecting the ideology of a colorless society. Through endless demonstrations of his father refusing segregation, either by the ministry or purchasing items in "white" merchant stores, King began to learn the balance of Grace and resistance.
While Dr. King is noted for his marches and protests against segregation, in reality, his father led hundreds of civil rights marches in politically driven public places. King Sr. was a brilliant pastor. He knew that the key to freedom in America was in voting in leaders that would sustain a colorless society – each bearing equal rights as citizens of the land of the free. King Jr. later referenced his father, saying, "My father was a real father to me." Again, who was the real hero in our story? |
Within the pursuit of assembly our local weather targets and reaching a seamless transition to renewable power sources, we encounter a formidable impediment: the necessity for environment friendly and sustainable power storage, particularly when counting on intermittent sources like photo voltaic and wind energy. Nevertheless, a beacon of hope emerges from Germany, the place a analysis consortium led by Fraunhofer IZM has set its sights on tackling this problem by groundbreaking zinc battery expertise.
This exceptional innovation not solely facilitates the storage {of electrical} energy but in addition has the distinctive functionality of manufacturing inexperienced hydrogen on demand. To comprehend this formidable imaginative and prescient, the analysis establishments have joined forces with two business companions, Zn2H2 and Metal PRO Maschinenbau, forming the Zn-H2 project.
A really new expertise
Diverging from standard lithium-ion batteries, the group selected to discover the potential of zinc batteries resulting from their financial benefits and the usage of fully-recyclable and available supplies: metal, zinc, and potassium hydroxide. The combination of alkaline water electrolysis into this battery composition resulted in a very new expertise.
Dr. Robert Hahn from Fraunhofer IZM supplied perception into the chemical processes that happen throughout the battery:
"Throughout charging, water oxidizes into oxygen whereas concurrently lowering the zinc oxide to metallic zinc. Upon discharge, the zinc returns to its oxide state, and the water is as soon as once more diminished, releasing hydrogen. This intricate mixture successfully marries the attributes of an ordinary battery with the performance of a hydrogen supply."
Lab exams on particular person battery cells have already been carried out to evaluate their effectivity and stability over a number of cycles, affirming the success of their revolutionary system. The staff now units its sights on testing eight interconnected cells, every boasting a capability of roughly 12V and 50Ah, by the 12 months's finish.
Anticipated outcomes point out promising figures, with an anticipated 50% effectivity in energy storage and a powerful 80% effectivity in hydrogen manufacturing, all whereas providing an estimated life expectancy of a decade for the system.
Trying to the longer term, the researchers envision an industrially-scalable, electrically rechargeable hydrogen storage system that serves a twin goal: storing power as metallic zinc and changing it again into electrical energy and hydrogen as wanted. Moreover, the cost-effectiveness of zinc batteries renders this expertise an interesting and viable various for business inexperienced power storage.
The important thing to decarbonizing high-emission industries
With the Zn-H2 undertaking slated to conclude in September 2025, it seeks to make substantial strides in facilitating our transition to inexperienced power.
Unlocking the total potential of inexperienced hydrogen, which at the moment includes a mere 1% of world hydrogen manufacturing, holds the important thing to decarbonizing high-emission industries, together with chemical compounds and metal manufacturing, whereas additionally offering electrical energy and warmth for home consumption. We're excited concerning the potentialities forward!

Modular Approach to a Sleep System
We originally published this blog back in 2015, partly as a response to the amazing feedback we had received to the blog posting 'Modular Packing Your Backpack' – how to keep order and keep your gear dry in your pack.
In 2015, it seemed as if very few people had given much thought to combining the correct sleeping pad, sleeping bag, and liner to form a system; so we gave a couple of examples of how and where this would work.
Fast forward to the present, and the term 'sleep system' is certainly more commonly used. Here's how we at Sea to Summit define it:
In order to get a good night's sleep, think of the gear you will need in the same way you think of a layered clothing system.
The first component is your ground insulation and comfort layer: the sleeping pad. This has to provide adequate insulation in the conditions you will be camping in, or the warmth from your sleeping bag will be lost into the ground. The second component is the insulation around your body: the sleeping bag. The shape, construction, and placement of insulation within the bag are going to be key, or your warmth will be lost into the air. The third component is the next-to-skin layer: the liner. This has the same function as a clothing base layer, wicking moisture and retaining warmth.
Let's start with the sleeping pad.
A sleeping pad has two functions: to provide comfort and to insulate you from the cold ground. Not every pad is as comfortable as some marketing departments would want you to believe, so it's essential to test one before you buy it by laying on the pad, and rolling over to assume different sleeping positions. If it wobbles underneath you, move on to a different design. Not all mats will insulate you from the ground equally well, either. Fortunately, a new industry standard will come into force in January 2020: all sleeping pad manufacturers will now test for the insulation value (R-Value) of their pads using the same test protocol. You will therefore be able to compare R-Values across brands.
The second component is the sleeping bag.
The sleeping bag is intended to retain your warmth when the outside air temperature is cool or cold. At the risk of repetition, not all sleeping bags retain heat as well as some people claim; not even the ones which are tested using the European EN rating system. Another factor to be aware of is the level of ventilation available in any given design. Some bags have plenty of ventilation options and can be used across a wide temperature spectrum, other bags have a much narrower comfort window.
The third component is a liner.
Most outdoor end-users have heard about sleeping bag liners. They may know that a liner can keep your sleeping bag clean, is easy to wash, and may add a few degrees of warmth. However, it's much less common to think of a liner as managing moisture in warm or humid conditions. Sea to Summit has liners which can add warmth and which can help keep you from feeling clammy when the temperature and humidity rise.
A modular sleep system for colder weather environments would work like this: the end-user can choose a slightly lighter and less bulky sleeping bag than otherwise would be the case, and pair it with a Reactor, Reactor Extreme, or Reactor Fleece liner to provide adequate warmth.
The sleeping pad would need to deliver the correct level of insulation, i.e. an R-Value of 3 or above. And the sleeping bag will be constructed with warmth-retaining features like a technical hood, a draft collar and a zipper draft tube large enough to really stop drafts. Because all the components in the system are optimized for the conditions in which they are being used, they offer the best possible performance for the least possible weight and packed volume. Compare this with the end-user who didn't plan in a modular way who carries around a heavier, bulkier sleeping bag without a thermal liner and without an adequately warm sleeping mat – and who is surprised when he or she gets cold.
By the way – the advice in this article is intended for all genders. However, women have specific needs when it comes to sleep systems which you can read about here.
A modular sleep system for warmer weather environments comprises of a sleeping mat with a lower R-Value (for summer use an R-Value of less than 1.0 is fine), a sleeping bag which can be gradually opened up for ventilation, all the way to forming a full quilt and a wicking liner. If you are traveling and sleeping primarily in hostels or even couch-surfing, you will probably not take a sleeping mat with you.
OK – on to those examples we mentioned above.
Imagine you're traveling through Southeast Asia: at the beginning of your trip (perhaps in Bangkok), you may be at a lower elevation in warm and humid conditions, maybe even in a budget-priced hotel or hostel. For these conditions, you would sleep in just the Breeze liner, which would help you sleep more comfortably while keeping you away from less-than-pristine bed sheets. (If there is concern about mosquitoes or bugs, you could also opt for the Breeze with Insect Shield). As you travel to higher elevations (say, Chiang Mai), you would sleep in the Breeze with the Trek (opened fully as a quilt) over you. As elevation increases further, you would progressively close the zippers (foot zipper and side zipper) on the Trek until at the coldest point of your trip you would be inside the Breeze in a fully cinched up sleeping bag.
In the above case, you would be traveling from hostel to hostel, and thus might not have a sleeping pad with you. A pillow, on the other hand, should definitely be part of this system.
Perhaps the most classic example of the use of a sleep system in moderately cold to warm conditions would be the Appalachian Trail. At the start of the trail in Georgia in April, an Ascent would keep you snug and warm with the Breeze inside it; you might even open the foot box zipper for a little ventilation. Further north in the chillier conditions of the Nantahala Forest, or perhaps the Mount Rogers Wilderness, you may well have all the zippers closed tightly. As you progress through Virginia, and the temperature and humidity increases you would progressively open the side zippers and eventually sleep under the Ascent opened like a quilt. In the hot humid nights in Pennsylvania, the Breeze by itself would suffice, before you head up to New England and once again use the system's ability to cope with increasingly cold nights.
The soft, stretchy liner will provide you with supreme comfort in both the above scenarios. The sleeping pad you would include in this system would have to provide an adequate level of insulation in those colder sections in Virginia and at the northern end of the trail. For this reason, a male end-user might choose the Insulated Ultralight Sleeping Pad (R-Value 3.1) or Ether Light XT Insulated Sleeping Pad (R-Value 3.2) while a female hiker would choose the Women's Ultralight Insulated Sleeping Pad (R-Value 3.5) or the Women's Ether Light XT Insulated Pad (R-Value 3.5)
For travel and general backpacking, the Trek is roomy and comfortable. It also has a lot more flexibility than many other sleeping bags because of their built-in ventilation.
However, given that weight and packed volume are often paramount on the AT, you may opt for the ultralight Spark Sleeping Bag which reduces your ventilation options, but also reduces weight and packed volume. A pillow is also a key element in a good night's sleep - and the Aeros Pillows are not only incredibly comfortable, they are light and very packable.
Sea to Summit sleeping pads are an integral part of any sleep system – they are more comfortable, easier to inflate and deflate and are made of higher quality materials than any other air-filled sleeping pad.
A Pillow is also a key element in a good night's sleep – and the aeros pillows are not only incredibly comfortable, they are light and very packable.
Finally, remember that the best sleeping bag and liner will only offer very modest comfort if they are wet or even damp. Make sure you pack them away in an appropriate dry-storage option inside your pack (you don't want to run the risk of snagging your sleep system or even your shelter on a sharp branch or rock). The Evac Compression Dry Bag and Evac Compression Dry Bag UL are all great candidates for packing away your sleep system.
If you have questions on which liner will work best with your sleeping bag, or which sleeping bag or sleeping mat is most suitable for a particular application, all you have to do is –

Pediatric Cardiology Fellowship Program | History of Cardiology at Boston Children's Hospital
Department of Cardiology staff, c. 1959-60
The Department of Cardiology was established in 1949, 11 years after a major milestone was achieved at Boston Children's by surgeon Dr. Robert Gross, who successfully ligated the first patent ductus arteriosus in a young girl. It was the world's first successful surgery for congenital heart disease.
Dr. Alexander S. Nadas, the "father of pediatric cardiology," added to that history by developing a rigorous pediatric cardiology program, and part of that work included founding the Cardiology Fellowship Program at Boston Children's in 1950. It is the oldest training program in the country. By the mid-1960s, the hospital had become the largest center for pediatric cardiology in the world, with 15 staff physicians as well as international recognition for cardiac research. But that was just the beginning: To this day, the Department of Cardiology has remained at the forefront of clinical and research training, with major contributions to many of the seminal advances in pediatric cardiology. Today, we have more than 80 staff physicians and nearly 400 fellowship alumni. |

Benefits of Proper Placement
When it comes to arranging furniture in your living room, the placement of your coffee table in relation to the sofa is an important consideration. The distance between these two pieces can greatly impact both the functionality and aesthetics of your space. Properly placed, your coffee table can enhance the overall design of the room and provide practical benefits that enhance your daily life.
One of the key benefits of proper placement is improved functionality. When the coffee table is positioned at the appropriate distance from the sofa, it allows for easy access and comfortable use. This means that you can easily reach for your morning coffee or a book without having to stretch or strain. Additionally, the proper distance ensures that you have enough space to comfortably place your feet on the floor or rest them on the edge of the coffee table, promoting relaxation and comfort.
Another advantage of proper placement is better traffic flow. By positioning the coffee table at the right distance from the sofa, you create a clear path for movement around the room. This is especially important in smaller spaces where every inch counts. With a well-placed coffee table, you can navigate around the room without obstacles, making the space feel more open and inviting.
Furthermore, the right placement of the coffee table can enhance the overall aesthetics of the room. When the coffee table is properly positioned, it becomes a focal point that complements the sofa and other furniture pieces. It helps to create a harmonious and balanced look in the living room. Whether you opt for a traditional or modern style, the proper placement of the coffee table can elevate the overall design and make a statement in your space.
Lastly, proper placement can also improve usability and functionality. When the coffee table is positioned at the right distance from the sofa, it allows for easy access to all its features. Whether you want to put down a tray of snacks, display decorative items, or have a space to place your remote control, having the coffee table within reach ensures that you can make full use of its surface area.
Factors to Consider
When determining the ideal distance between your coffee table and sofa, there are several factors to take into consideration. These factors will help you find the perfect balance between functionality and aesthetics, ensuring that the placement suits your specific needs and preferences.
Firstly, consider the size and proportion of your furniture pieces. If you have a larger sofa, you might want to position the coffee table a bit further away to maintain a sense of balance. Conversely, a smaller sofa might look better with the coffee table placed closer for a cozy and intimate feel. Additionally, consider the height of your sofa and coffee table. You'll want to ensure that the table is within reach and that there's enough space above it to comfortably move around.
Secondly, think about the overall layout of your living room. Consider the placement of other furniture and accessories, such as chairs, side tables, and entertainment units. The coffee table should fit seamlessly into the space without obstructing pathways or creating visual clutter. It's important to maintain a sense of flow and harmony in the room.
Next, consider the functionality you desire from your coffee table. Do you plan to use it primarily for holding drinks and snacks while watching TV? Or do you envision it as a display area for books and decorative items? The intended use will impact the ideal distance from the sofa. For practical purposes, you'll want it close enough to easily reach, while still leaving enough space for other activities or movement around the room.
Another factor to consider is the style and design of your living room. Is it a more traditional or formal space, or a modern and eclectic one? The placement of your coffee table can reflect and enhance the overall style. For traditional styles, a coffee table positioned closer to the sofa might be more appropriate. In contrast, for a modern and minimalist look, you could experiment with placing the coffee table further away or even using alternative options, like ottomans or side tables, to create a unique and visually appealing arrangement.
Lastly, it's important to consider your personal preferences and lifestyle. Everyone has different needs and preferences when it comes to furniture placement. Some individuals may prefer a more open and spacious living room with ample legroom, while others may enjoy a cozy and intimate setting. Take into account how you and your family typically use the space and what feels most comfortable and functional for you.
By considering these various factors, you can make an informed decision about how to position your coffee table in relation to the sofa, ensuring that it enhances both the functionality and aesthetics of your living room.
Traditional Placement Guidelines
Over the years, certain guidelines have emerged when it comes to the traditional placement of a coffee table in relation to the sofa. These guidelines have been followed by many homeowners and interior designers to create a classic and timeless arrangement in the living room.
One common traditional placement guideline is to position the coffee table approximately 18 inches away from the sofa. This measurement allows for sufficient space to walk around and access the seating area comfortably. It also ensures that the coffee table is within arm's reach, making it convenient for placing drinks, books, and other items while lounging on the sofa.
In terms of positioning, the coffee table should typically be centered in front of the sofa, aligning with the middle of the seating area. This symmetrical placement helps to create a balanced and visually pleasing arrangement. It also allows for equal access to the coffee table from all sides of the sofa.
Another traditional guideline is to ensure that the coffee table is proportional to the size of the sofa. A general rule of thumb is to select a coffee table that is about two-thirds the length of the sofa. This helps to maintain visual harmony and proportion in the room.
Additionally, consider the height of the coffee table in relation to the sofa. A general guideline is to choose a coffee table that is around the same height as the seat cushions of the sofa or slightly lower. This ensures that the table is at a comfortable level for placing items on it, without obstructing the view or creating an awkward height difference between the sofa and the table.
Following these traditional placement guidelines can help create a classic and symmetrical look in your living room. However, it's important to remember that these guidelines are not set in stone and should be tailored to your individual space and preferences. Ultimately, the goal is to find a placement that is both functional and visually appealing for you and your family.
Modern Placement Trends
While traditional placement guidelines have their charm, modern interior design trends have brought about new and exciting ways to position a coffee table in relation to the sofa. These trends embrace creativity, asymmetry, and versatility, resulting in unique and personalized living room arrangements.
One modern placement trend is to experiment with different shapes and sizes of coffee tables. Rather than sticking to the conventional rectangular or square shapes, homeowners are opting for circular, oval, or even irregularly shaped coffee tables. This adds an element of visual interest and breaks away from the traditional norms, allowing for more fluidity and creativity in the overall layout.
Another trend is to place the coffee table slightly off-center from the sofa. By intentionally shifting the position, you can create a visually dynamic arrangement. This asymmetrical placement adds a sense of movement and highlights the coffee table as a focal point in the room. It also allows for more flexibility in terms of space utilization, as you can add additional seating or accent furniture to the other side of the sofa.
Incorporating multi-level or nesting coffee tables is another popular modern trend. With these types of tables, you can add depth and dimension to your living room. They offer a practical solution for those in need of additional surface area, as you can easily expand or contract the table depending on your needs. This versatility is particularly useful when entertaining guests or needing extra space for activities in the living room.
Furthermore, modern placement trends often embrace eclectic and mix-and-match styles. Instead of using a single coffee table, homeowners are experimenting with a combination of different-sized tables or alternative options like ottomans, stools, or even vintage trunks. This creates an eclectic and personalized look, reflecting the homeowner's unique style and personality.
It's worth mentioning that modern placement trends prioritize functionality and adaptability. Homeowners are opting for coffee tables with built-in storage compartments or adjustable heights. These features provide practical solutions for storing remote controls, books, magazines, and other items, while also allowing for customization based on individual preferences and needs.
Embracing modern placement trends allows you to express your creativity and create a living room arrangement that truly reflects your personal style. Whether you choose to incorporate unconventional shapes, asymmetrical layouts, or alternative furniture options, the key is to find a placement that suits your lifestyle and brings a sense of joy and individuality to your space.
Distance for Functionality
When considering the distance between your coffee table and sofa, functionality plays a crucial role. The right distance ensures that you can easily access and utilize the coffee table in a practical and convenient manner.
First and foremost, the distance should allow for easy access to the tabletop surface. You should be able to comfortably reach the coffee table from the seated position on the sofa without straining or stretching too far. This is particularly important if you frequently use the table to place drinks, snacks, or other items while relaxing on the sofa. A distance of around 16 to 18 inches between the edge of the sofa and the coffee table is often recommended for optimal functionality.
In addition to reachability, the distance between the coffee table and sofa should provide enough space for legroom. One of the key factors in determining this distance is the height of the coffee table. Ideally, there should be enough space for you to comfortably rest your feet on the floor while seated on the sofa. This allows for proper circulation and a relaxed sitting position. Typically, a distance of 12 to 18 inches between the bottom of the coffee table and the top of the seat cushions provides sufficient legroom.
Furthermore, consider the type of activities you plan to engage in while using the coffee table. If you often work on your laptop or enjoy crafting or other hobbies, you may require a larger distance between the sofa and the coffee table to accommodate these activities. This ensures that you have enough space to comfortably place your laptop, materials, or tools, allowing you to work or indulge in your hobbies without feeling cramped or restricted.
It's worth noting that the distance for functionality is not set in stone and may vary depending on individual preferences and the specific dimensions of your furniture. Experimenting with different distances can help you find the balance that best suits your needs. Ultimately, the goal is to have a distance that allows for easy access, comfort, and usability, making your coffee table an integral and functional part of your living room setup.
Distance for Aesthetics
In addition to functionality, the distance between your coffee table and sofa also has a significant impact on the overall aesthetics of your living room. Finding the right distance can help create a visually pleasing and harmonious arrangement, adding to the overall appeal of the space.
One key aspect to consider is the balance and proportion between the coffee table and the sofa. The distance should be chosen in a way that maintains a sense of visual harmony. If the coffee table is too close to the sofa, it may create a crowded or cluttered look. Conversely, if it is positioned too far away, it might appear disconnected or awkward. Striking the right balance in the distance helps create a cohesive and aesthetically pleasing arrangement.
Moreover, the distance can contribute to the overall flow and spatial arrangement of the room. Placing the coffee table at an appropriate distance from the sofa helps define the seating area and establish a sense of order in the living room. This can be particularly important in open-concept spaces where delineating different functional areas is key. A well-balanced and visually appealing arrangement enhances the overall aesthetics, making the living room feel more inviting and put together.
Consider the style and design of your living room when determining the distance for aesthetics. If you have a traditional or formal space, a slightly closer distance between the coffee table and the sofa may create a more classic and refined look. On the other hand, if you have a modern or contemporary living room, placing the coffee table a bit further away might contribute to a sleek and minimalist aesthetic. Aligning the distance with the overall style of the room ensures a cohesive and visually pleasing arrangement.
Furthermore, the distance between the coffee table and sofa can also impact the perceived spaciousness of the room. Placing the coffee table a bit further away from the sofa can create an illusion of more open space. This can be particularly useful in smaller living rooms or in situations where you want to make the room feel larger and more airy. On the other hand, a closer distance can create a cozy and intimate feel, ideal for creating a warm and inviting atmosphere.
Ultimately, finding the right distance for aesthetics is a subjective decision that should align with your personal taste and the overall design of your living room. Experimenting with different distances can help you determine what works best for your space, allowing you to create a visually appealing arrangement that enhances the overall aesthetics of your living room.
Finding the Right Balance
When it comes to positioning your coffee table in relation to the sofa, finding the right balance is crucial. This involves considering both functionality and aesthetics to create an arrangement that suits your needs and enhances the overall appeal of your living room.
Start by assessing the space and dimensions of your living room. Measure the area between the sofa and the potential placement spot for the coffee table. Take into account any other furniture or accessories in the room, ensuring that there is enough space to move around comfortably and maintain a sense of flow.
Next, consider the intended use of the coffee table. If you primarily use it for holding drinks and snacks, a distance that allows for easy reach and accessibility is important. On the other hand, if the coffee table serves as a display area or a workspace, you may need a larger distance to accommodate these activities. The right balance will depend on how you plan to utilize the coffee table in your day-to-day life.
Pay attention to the style and design of your living room as well. The distance between the coffee table and sofa should complement the overall aesthetic and create a cohesive look. Consider the proportions of the furniture pieces, ensuring that the size and height of the coffee table harmonize with the sofa and other elements in the room. Finding the right balance helps create a visually pleasing arrangement that feels well-coordinated and intentional.
Keep in mind your personal preference and lifestyle. Consider how you and your family use the living room. Do you value ample legroom and open space, or do you prefer a more intimate and cozy atmosphere? Taking these factors into account will help determine the ideal distance that aligns with your individual needs and preferences.
It's important to note that the right balance may require some trial and error. Don't be afraid to experiment with different distances and rearrange the furniture until you find the arrangement that feels perfect for you. Consider the feedback from family members or friends who use the space to ensure that the chosen distance accommodates everyone's needs and creates a comfortable and inviting atmosphere.
Remember, the ultimate goal is to strike a balance that combines functionality and aesthetics. Finding the right distance between the coffee table and sofa can transform your living room into a well-designed and enjoyable space that reflects your style and enhances your everyday life.
Tips for Measuring Distance
Measuring the distance between your coffee table and sofa accurately is essential to achieve the ideal placement. Here are some helpful tips to ensure precision when determining the distance:
- Use a tape measure: A tape measure is a valuable tool for obtaining accurate measurements. Extend the tape measure from the edge of the sofa to the desired placement spot for the coffee table, ensuring it remains straight and taut. This will provide an exact measurement of the distance between the two pieces.
- Consider walkways: When measuring the distance, take into account the walkways around the coffee table and sofa. Allow enough space for easy movement and accessibility. Leave about 18 inches of clearance between furniture and walls or other obstacles to create a comfortable pathway.
- Account for legroom: If you prefer to have a significant amount of legroom between the sofa and coffee table, measure from the front edge of the sofa to the potential placement spot for the coffee table. Ensure that you have enough space to comfortably extend your legs without feeling cramped or restricted.
- Factor in table size and shape: If you have a specific coffee table in mind, consider its size and shape when measuring the distance. Measure the length, width, and height of the table to determine how it will fit in the allotted space. Make adjustments to the distance based on the dimensions of the chosen table to ensure a balanced and proportional arrangement.
- Visualize the arrangement: Before finalizing the distance, take a step back and visualize the overall arrangement. Consider the scale and proportion of the coffee table in relation to the sofa and other furniture in the room. Imagine how the space will look and feel once the coffee table is placed. This can help you make any necessary adjustments to achieve the desired aesthetic and functionality.
Remember, accuracy is key when measuring the distance between your coffee table and sofa. By following these tips, you can ensure that the placement is precise and well-suited to your space, resulting in a visually appealing and functional arrangement in your living room.
Creative Alternatives to Traditional Placement
While traditional placement guidelines provide a solid foundation for positioning your coffee table in relation to the sofa, thinking outside the box and considering creative alternatives can result in a unique and visually captivating arrangement in your living room. Here are some creative alternatives to traditional placement:
- Use multiple coffee tables: Instead of sticking to a single coffee table, consider using multiple tables of varying shapes and sizes. This adds an element of visual interest and versatility to your living room. Experiment with arranging them in a cluster or in a scattered formation. This unconventional approach creates a dynamic and modern look.
- Opt for asymmetrical placement: Embrace asymmetry by placing the coffee table off-center from the sofa. This creates a visually intriguing focal point and adds a touch of uniqueness to your space. Consider positioning the coffee table closer to one end of the sofa, leaving more open space on the other side. This creates an unexpected and stylish layout.
- Explore alternative furniture options: While a traditional coffee table is a popular choice, think outside the box and consider alternative furniture options. Ottomans, poufs, or even a combination of low stools and small side tables can add a touch of personality and functionality to your living room. These alternatives provide a more versatile seating and surface area configuration.
- Incorporate nesting tables: Nesting tables are a practical and stylish alternative to a single coffee table. These tables can easily be stacked together when not in use, saving space and providing additional surface area when needed. The varying heights and sizes of nesting tables add visual interest and allow for flexible positioning in your living room.
- Consider ottomans with hidden storage: If you're looking to maximize storage space while adding a touch of elegance to your living room, consider using an ottoman with hidden storage. These versatile pieces of furniture serve as both a coffee table and a storage solution. You can use them for seating or as a footrest while enjoying the added benefit of concealed storage for blankets, pillows, or other items.
When exploring creative alternatives to traditional coffee table placement, consider the style and layout of your living room, as well as your personal preferences. Play with different arrangements, experiment with various furniture options, and let your creativity guide you in creating a unique and visually stunning arrangement that suits your lifestyle and showcases your individuality. |

Recovery of halophytic vegetation on the margin of tidal flats following a wildfire at Padre Island National Seashore, Texas, was studied for 26 months. Species richness, species diversity, species importance, evenness and vegetation abundance were evaluated. Species richness and diversity were restored within 108 days after the fire. Sporobolus virginicus was the dominant species on both burned and non-burned transects. Vegetative cover was slow to recover. It took 19 months for cover of burned areas to equal or exceed cover of non-burned areas. Biomass also was slow to recover and it did not equal biomass of non-burned transects in 26 months. Species colonizing the burned transects were mostly species in nearby non-burned areas. Only one exotic species (Polypogon monspeliensis) appeared in the burned transects. The principal way that fire affected the tidal flats community was in the reduction of standing dead plants and surface litter.

With Hybrid Work, When & Where Does Learning Happen?
Let me ask you a question. Can you define mobile learning? Is "mobile learning" a learning technology, a design technique, or something else...
The hybrid work model has been increasing in adoption since the pandemic. The analysis of thousands of tasks and jobs across multiple countries indicates that more than 20% of the workforce could work as effectively, not losing productivity, in a hybrid model. This data from McKinsey & Company underscores the viability and necessity of adopting a hybrid approach.
Making hybrid work thrive involves an environment that emphasizes communication, connection, collaboration, and creation. Coincidentally, these are the same pillars upon which robust hybrid learning environments are built.
Hybrid learning has been utilized for many years. Among the insights of InSync's 2024 research report, "Hybrid Learning: How to Engage Learners and Produce Real Outcomes" we find valuable lessons for enhancing hybrid work cultures. The findings reveal several parallel needs and strategies between hybrid learning and hybrid work environments, including:
Designing with intention: Similar to instructional content, work policies and practices in a hybrid environment must be deliberately designed for such settings. Without this intentionality, the result can be a disjointed experience that may leave remote team members feeling excluded.
Fostering inclusivity: The negative reaction learners have when they feel excluded from delivery highlights the importance of inclusivity in the hybrid workplace. Ensuring every team member feels valued and included, regardless of their location, is crucial for maintaining engagement and morale.
Strategic Design, Cohesion, and Inclusivity
Strategic planning is essential to the success of hybrid work environments. With the dynamic nature of hybrid work, careful strategic planning becomes essential to encourage effective communication, maintain productivity, and uphold company culture. A well-thought-out strategy encompasses clear guidelines on remote work protocols, technological infrastructure, and performance management systems tailored to accommodate both in-person and remote collaboration. Strategic planning facilitates the implementation of flexible scheduling policies that accommodate diverse employee needs while ensuring operational continuity. By proactively addressing challenges such as team cohesion, work-life balance, and equitable opportunities for all employees, strategic planning lays the foundation for a thriving hybrid work environment conducive to innovation, collaboration, and sustained success.
In addition, inclusivity plays a role in ensuring every team member feels valued and included. Creating a cohesive and engaging workplace is essential. The perception of hybrid instructional content as piecemeal poses a similar risk in hybrid work environments to what it does in learning environments. A unified strategy that smoothly integrates remote and in-office experiences is essential to prevent distractions and enhance overall effectiveness.
The tendency of learners to disengage from poorly designed hybrid instruction mirrors the potential for employee disconnection in suboptimal hybrid work settings. Conversely, engagement levels can match or exceed traditional methods when the hybrid model is well-executed.
Skill Development in Hybrid Settings
A well-designed hybrid environment acts as a catalyst for skill development that can lead to significant company growth. Well-implemented hybrid learning not only educates but also imparts valuable collaboration and interaction skills. Similarly, thoughtfully structured hybrid work environments can serve as platforms for continuous skill development, equipping employees for the complexities of contemporary work dynamics.
The Four C's of Hybrid Work Culture: Communication, Connection, Collaboration, and Creation
The four C's - communication, connection, collaboration, and creation each contribute to the success of a hybrid work culture. The essence of a great hybrid work culture can be condensed into these four key components, as follows:
Communication: Effective communication is the heartbeat of any productive hybrid workspace. In the absence of clear communication norms, teams can become disjointed and misaligned. Providing various "non-live" communication platforms and establishing norms regarding their use—such as expected response times and level of detail in shared information—ensures a cohesive and efficient working environment.
Connection: Building a sense of connection among remote and in-office team members requires intentionality. Without feeling connected, employees can quickly become disengaged, impacting morale and productivity. This is just as true in a learning environment as it is in day-to-day operations. It's not just about adding some technology or tools; it's also about ensuring leaders are intentionally reaching out and making connections with their teams. Creating moments for informal virtual coffee chats or regular check-ins can foster a sense of belonging and community, bridging the gap between physical distances.
Collaboration: Collaboration is crucial in a hybrid setup, and technology plays a key role. Tools that facilitate seamless collaboration across global teams are not only necessary but expected. The technology should be intuitive, allowing for real-time engagement and cooperation on projects and learning tasks. Beyond just providing the tools, it's essential to cultivate an atmosphere of psychological safety where everyone feels encouraged to share their ideas. Ensuring that all voices are heard and valued leads to a more inclusive and innovative workplace, where diverse perspectives drive better outcomes.
Creation: Creativity in hybrid work cultures manifests through the freedom and flexibility to brainstorm and innovate regardless of physical location. In a learning context, creativity leads to interactive and stimulating programs that encourage critical thinking and problem-solving abilities. The impact of stifling creativity in both environments can be far-reaching, leading to a decline in innovation and overall competitiveness of the training or business.
Preparing individuals to excel in hybrid settings requires instilling skills essential for effective online and offline interactions. These skills extend from using the mediums by which we engage with colleagues, to how we participate in team-based activities, to how we integrate learning into daily work life.
What Makes Hybrid Work?
While the four C's are traits that everyone in the business should work to develop, there are also some systems and norms that should be put in place to help hybrid work smoothly.
Easy Access to Non-Live Communication: It's critical to provide various channels for "non-live" communication and to establish norms for their use, such as expected responsiveness and requisite detailing. Just as this practice keeps a workforce connected and informed, it also propels a learning culture where queries and discussions can flow freely and asynchronously.
Content Accessibility and Relevance: Whether it's the company knowledge base or the Learning Management System (LMS), content should be readily accessible and regularly updated. By embedding microlearning assets directly into the workflow, employees can apply new knowledge in real time, with the added benefit of tracking utility and relevance. This approach is further enhanced when employees can contribute feedback, fostering continuous improvement, and promoting a learning culture among their teams.
Managerial Engagement and Top-Down Culture: Culture cascades downward; hence, managers must model the hybrid-friendly behaviors they expect from their teams. From how they interact to how they champion the use of tools and resources—leadership sets the tone for a thriving hybrid ecosystem.
Insights from InSync Training's research on hybrid work illuminate the need for these systems. The report advocates well-crafted training design and delivery that support hybrid work. The intersection of work and learning is where individuals will become adept at navigating the fluidity of modern work environments.
Reflecting on the Journey and Looking Ahead
When aiming to foster a vibrant hybrid work culture, there are several critical points to take into consideration to ensure the success and cohesion of the team. First, clear and consistent communication channels must be established to facilitate seamless collaboration among remote and in-office employees. Regular team meetings, virtual check-ins, and transparent communication platforms help bridge geographical gaps and keep everyone informed and engaged. Second, cultivating a strong sense of trust and autonomy is essential to empower employees to succeed in both remote and office settings. Providing flexibility in work hours and embracing outcome-based performance evaluations fosters a culture of accountability and ownership.
Third, prioritizing employee well-being by promoting work-life balance, and fostering a culture of empathy and understanding creates a supportive environment where individuals can thrive personally and professionally. Finally, investing in technology and infrastructure to enable smooth remote collaboration, provide access to necessary resources, and ensure equitable opportunities for all team members is paramount for building a cohesive and inclusive hybrid work culture. By prioritizing these critical points, organizations can create a vibrant hybrid work culture that promotes innovation, collaboration, and employee satisfaction.
Hybrid Work and Hybrid Learning—a Perfect Match
The crux of a high-performing hybrid culture lies in its core characteristics—flexibility, accessibility, and adaptability—enabled through solid communication, strong connections, collaborative efforts, and creative approaches to problem-solving. Whether it's the domain of work or learning, these traits are indispensable.
For HR professionals, training managers, and practitioners, the task is clear. By nurturing these qualities within learning environments, we're implicitly equipping our workforce with the skills necessary to not only survive but thrive in hybrid work settings. In turn, these practices promise to enrich the organization's growth and cultivate an ethos of continuous learning and adaptability.

Vitamins A
Always consult your primary physician when starting a nutrition program with Vitamins A.
Vitamin A is the name of a group of fat-soluble retinoids, including retinol, retinal, and retinyl esters [1-3]. Vitamin A is involved in immune function, vision, reproduction, and cellular communication [1,4,5]. Vitamin A is critical for vision as an essential component of rhodopsin, a protein that absorbs light in the retinal receptors, and because it supports the normal differentiation and functioning of the conjunctival membranes and cornea [2-4]. Vitamin A also supports cell growth and differentiation, playing a critical role in the normal formation and maintenance of the heart, lungs, kidneys, and other organs [2].
Vitamin A is key for good vision, a healthy immune system, and cell growth. There are two types of vitamin A. This entry is primarily about the active form of vitamin A -- retinoids -- that comes from animal products. Beta-carotene is among the second type of vitamin A, which comes from plants.
The American Heart Association recommends obtaining antioxidants, including beta-carotene, by eating a well-balanced diet high in fruits, vegetables, and whole grains rather than from supplements until more is known about the risks and benefits of supplementation.
High doses of antioxidants (including vitamin A) may actually do more harm than good. Vitamin A supplementation alone, or in combination with other antioxidants, is associated with an increased risk of mortality from all causes, according to an analysis of multiple studies. |

A new life doesn't come easily — a Bangladeshi immigrant shares her experiences starting over in Halifax
When textile engineer Tori Bhattacharya (name changed) graduated from university in her native Bangladesh, she wanted to pursue her career abroad, a path she didn't follow until settling in Halifax in October 2021.
"After completing my engineering degree, I wanted to go to the U.S. or Germany for higher studies, but my conservative parents believed it wouldn't be safe for me to travel to or live in a foreign country all by myself," she recalls.
When asked why she came to Canada, she says, "Oh, that is a long story. My sister's friend used to come home often and slowly we got to know her family. Her brother had recently settled down in Canada. They were looking for a bride for him and they proposed marriage between me and him. Later we were introduced, photographs exchanged, and we communicated over the telephone for some months."
During Christmas holidays, he went to Bangladesh, and they married. "Ten days after our wedding he had to return to Canada," she says. "I applied for a Canadian visa which took 10 months to come through."
Travelling alone during the pandemic was hard. "It was my first journey to a foreign country, and I found it long and exhausting," Bhattacharya says.
Her reaction to Halifax was mixed. "When I reached here, my husband, his sister, and her family were waiting to welcome me to my new home," she says. "It was a happy occasion. But I found the city too small and sparsely populated."
The Canadian climate was a shock.
"As soon as I got down from the plane, the cold air hit me," she says. "For someone like me who had lived in a tropical country all her life, Canadian air felt too cold even in October. Then the snow came, and I shivered in spite of the many layers of clothing I was wearing. And shovelling snow was back breaking."
Bhattacharya had to quickly learn all those little tricks for surviving winter that seasoned Canadians take for granted. "I found walking on the snow really difficult," she says. "I had to wear bulky winter boots and practise walking. I fell a few times and once I hurt my arm and leg badly. I shudder at the thought that I will have to face winter every year."
And things got worse. "After I came to Canada, I suffered from severe vitamin deficiency," she says. "My mouth was covered with sores, and I got very sick. I was in excruciating pain. In four months, I had to go to the hospital emergency department three times. Every time I had to wait for seven to eight hours before I could get any help. My husband was working, and I had to go there alone. I sat there and cried every time."
She believes it would've been much easier to get the health care she needed back in Bangladesh. "There, I could walk into any clinic or private hospital and get immediate help," she says. "If I didn't have money, I could go to a government hospital where emergency cases are attended to without much delay. I am concerned about my health, and I am afraid. What will I do if I become seriously ill again?"
Today, her most pressing need is a career. "I have been sending out applications for jobs, but received no response from any employer," she says. "I realize that a degree in textile engineering will not be of much use. My best bet, I think, will be to take a two-year course in information technology and then look for work in that field."
And meanwhile, Bhattacharya hopes for warmer weather, and tries to stay patient and persevering. |

Gateley charts the natural history of Lake Ontario from its ice age origins to the climate and habitat challenges it faces today. |
Site Design for a Hotel in Pantops, Charlottesville; Analysis of Sociotechnical Failures that Lead to the Partial Collapse of Champlain Towers South
Warren, Garrett, School of Engineering and Applied Science, University of Virginia
Laugelli, Benjamin, EN-Engineering and Society, University of Virginia
Heydarian, Arsalan, EN-CEE, University of Virginia
My technical project and STS research are connected through a shared focus on the challenge of resiliency, or the ability to withstand, respond to, and recover from disruptions. However, the approaches to resiliency and its application differ between the two works. My technical project concentrates on addressing resiliency during the preconstruction phase. Here, the emphasis is on ensuring the protection of the natural environment and the robustness of the site layout as the project is being built. In contrast, my STS research explores how to maintain resiliency over the useful lifecycle of a building, as well as the consequences of its potential failure. This work delves deeper into the complex interactions between human and non-human actors, examining how the various elements of the socio-technical network influence the building's resilience throughout its operational phase. By integrating these perspectives, my work provides a comprehensive understanding of the challenges and strategies for enhancing the resilience of built environments from the preconstruction stage through a building's lifecycle.
My technical work involved developing a set of construction documents for a proposed hotel in Charlottesville, Virginia, for a private developer client. The constraints set forth by the owner included meeting 75% stormwater quality requirements onsite, meeting all stormwater quantity requirements onsite, and incorporating a 14,000-sf building on site with 80 parking spaces. Throughout the year, my project team went through multiple design iterations to determine the best site layout, building orientation, parking design, grading, stormwater management, utility design, and erosion control plans that complied with relevant county codes, state regulations, and federal environmental requirements. Key challenges included designing adequate stormwater best management practices, proper grading for accessibility, and optimizing the site layout to integrate all the design components within the constraints of the compact lot.
My STS research relies upon the framework of actor-network theory (ANT) to analyze the partial collapse of Champlain Towers South that killed ninety-eight people. ANT emphasizes the importance of not only human actors, but also non-human elements, in shaping the success or failure of technological projects and their societal impacts. My research focuses on creating an actor-network in which the developers and owners are the primary actors responsible for the network construction. My analysis aims to understand how the various human and non-human actors interacted and influenced each other within the network, and how the initial network formation and translation process broke down over time. The conclusion I reached challenges the perspective that places sole responsibility on the engineers and architects. Instead, I argue that a culmination of factors was likely the cause of the partial collapse.
Working on both projects simultaneously provided a valuable opportunity to inform one another during the academic year. The technical project's focus on the preconstruction phase allowed me to develop a practical understanding of the engineering standards that go into design. At the same time, my STS research provided insights into the broader socio-technical factors that can destabilize a structure over its lifecycle. These two projects highlighted the importance of adopting a holistic approach to resilience, one that considers not only the technical aspects but also the ongoing maintenance, environmental changes, and stakeholder interactions. Moving forward, I will apply the insights from my STS research to future technical projects, recognizing the need for a comprehensive understanding of socio-technical networks and the potential long-term implications of design decisions on a building's resilience.

An analysis by YavuzAkbay on TradingView looks at historical Bitcoin halving cycles and technical indicators to forecast a potential six-figure BTC price by 2025. Every four years, the Bitcoin protocol halves the block reward paid to miners. Historically, these "halving" events have preceded parabolic bull runs in the BTC price.
What you'll learn 👉
Historical Halvings Spark Massive Bull Runs
Three halving-driven bull cycles have occurred since Bitcoin's creation in 2009. After the first halving in late 2012, BTC rose nearly 10,000% over the next year. The second halving in mid-2016 kicked off a rally of over 3,000% to almost $20,000 by late 2017. Most recently, 2020's halving ignited a 550% surge to an all-time high above $64,000 in 2021.
Fibonacci Levels Map Out Peak Price Targets
Each bull run peaked around key Fibonacci retracement levels when applied to the bear market preceding it. The 2013 top occurred near the 3.618 Fib level of the 2011 bear trend. The 2017 apex aligned with the 2.618 level of the 2014-2015 bear. And 2021's peak hit the 1.618 Fib of the 2018-2020 bear. This declining sequence of Fib ratios reflects Bitcoin's logarithmic price charts.
Based on the current bear market that began in late 2021, the 1.382 Fib level points to an optimistic target above $100,000 by the next halving cycle peak in 2025. More conservative targets at higher Fib levels remain possible if the bull run exceeds expectations.
The RSI indicator also peaks consistently around halvings, but with diminishing intensity over time. This favors a lower RSI peak over the next cycle, likely in late 2024 or early 2025 based on historical timing.
When the RSI dips below 50 it has reliably marked Bitcoin bottoms. This signaled optimal buying opportunities after previous halving-related corrections. Currently it suggests possible entry points around $20,000 if BTC retests lows.
In summary, halving cycles and technical indicators point to six-figure Bitcoin prices by 2025. Investors should consider building positions around the next halving and utilizing cost averaging to weather volatility. As with any forecast, realize actual market action may deviate from modeled targets. But probability favors tremendous upside ahead.

In the exhilarating world of gambling, fortunes can be won or lost in the blink of an eye. The allure of the unknown, the thrill of taking risks, and the promise of quick riches draw countless individuals into the heart-pounding realm of chance and possibility. From the glitzy casinos of Las Vegas to the bustling betting shops on city corners, gambling permeates various facets of society, offering both excitement and peril to those who partake. With a history that spans centuries, gambling has evolved into a global phenomenon that captivates players of all walks of life.
Types of Gambling
One of the most common forms of gambling is casino gambling. This includes games like blackjack, roulette, and slot machines where players wager money in the hopes of winning more.
Another popular type of gambling is sports betting. This involves predicting sports outcomes and placing bets on various events such as football games, horse races, or boxing matches.
Lotteries are also a prevalent form of gambling where participants purchase tickets in the hopes of winning a prize. These games of chance are often based on random number drawings with large potential payouts.
Effects of Gambling
For many individuals, gambling can have both positive and negative effects on their lives. Some people find that the excitement and thrill of gambling provide a temporary escape from their daily stresses. The adrenaline rush that comes with placing a bet can be addictive, leading to feelings of euphoria and excitement.
However, gambling can also have detrimental effects on individuals and their loved ones. Problem gambling can cause financial strain, leading to debt and strained relationships with family and friends. The constant need to chase losses can result in a vicious cycle of compulsive gambling behavior, impacting mental health and overall well-being.
Furthermore, the societal impacts of gambling cannot be ignored. Problem gambling can lead to an increase in crime rates, including theft and fraud, as individuals resort to desperate measures to fund their habit. In addition, communities with a high prevalence of gambling establishments may experience an increase in social issues related to addiction and gambling-related harm.
Responsible Gambling
Gambling can be a thrilling form of entertainment for many individuals, but it is essential to approach it with caution and responsibility. One key aspect of responsible gambling is setting limits for oneself before engaging in any form of betting or wagering activities. By establishing predefined boundaries on the amount of money and time you are willing to invest in gambling, you can help ensure that it remains an enjoyable pastime without leading to negative consequences. keluaran hk
Another crucial element of responsible gambling is being aware of the potential risks and understanding the odds associated with various games. Educating oneself about the mechanics of different gambling activities can contribute to making informed decisions while participating in such activities. It is important to remember that the house always has an edge in most games of chance, and engaging in gambling should be viewed as entertainment rather than a reliable means of making money.
Seeking help and support when needed is a fundamental part of responsible gambling. If you or someone you know is experiencing issues related to excessive gambling behavior, it is crucial to reach out to support services such as helplines, counseling, or support groups. Recognizing the signs of problem gambling early on and taking proactive steps to address them can lead to a healthier relationship with gambling and prevent potential harm in the long run. |
To detail a car is to clean and protect every inch, both inside and out, until it sparkles like new. The time it takes to detail a car can vary dramatically, influenced by factors like the size of the vehicle, its condition, and the detailing services requested.
When we roll up our sleeves to begin detailing, it's more than a commitment – it's the question
How Long Does It Take to Detail a Car?
On average, a thorough detail will take at least a few hours, but we could be investing up to a full day or more.
Detailing Basics: Understanding the Process
Car detailing is an art that demands both time and precision.
Let's jump in and unpack the whole process.
Time-Intensive Steps of Detailing a Car
The journey to a stunning car begins with a decontamination wash, which removes the deep-seated dirt and paves the way for paint correction to eliminate scratches.
Next, clay bar treatment and polishing prep set the stage for a glorious finish. Interior detail includes vacuuming and cleaning all nooks, whereas the exterior detail may require up to two days for a thorough job.
Essential Tools and Materials
From microfiber towels to pressure washers, the right tools make all the difference. We'll need a microfiber wash mitt, high-quality car shampoo, and detailing spray for that touch of perfection.
Compounds, waxes, and sealants are also crucial for that protective layer.
Factors Influencing Detailing Duration
How long we spend on detailing can vary significantly. The size and age of your car, coupled with the dirtiness of the paintwork, play a big part. Detailing a sedan takes fewer hours than a full-fledged full detail on a large SUV.
Vehicle Condition and Preparation for Detailing
A regularly maintained car makes the detailing process faster.
We must assess the car's paint decontamination needs and look out for oxidation or clear coat damage.
Proper preparation cuts down on time and enhances results.
Protecting Your Car Post-Detailing
After the hard work, protecting the finish is key.
We apply tire dressing and discuss options like paint protection film, ceramic coatings, or wax to safeguard against UV rays and keep that gloss lasting longer.
This final step ensures our efforts stand the test of time.
Detailing for Preservation and Aesthetics
When we talk about detailing a car, we're investing in more than just its shine.
The goal is to preserve the materials used across your vehicle through detailing and enhance its beauty, making every inch gleam.
Enhancing Vehicle Appearance
We know that the impact of a gleaming exterior can be profound. Exterior detailing typically involves a thorough wash, the careful application of wax, and paint correction techniques. With polish and sealant, those subtle swirls and scratches fade away.
Properly addressing the grille, gas cap, and other often-overlooked areas with a detailing spray ensures that no detail is too small to shine.
Long-Term Benefits of Regular Detailing
Regular detailing is a crucial part of maintenance.
For instance, a ceramic coating might seem like a luxury, but it's a robust barrier against the elements.
Similarly, maintaining interior surfaces and leather seats with the right cleaner can prevent premature wear.
Regularly scheduled interior detailing helps avoid costly repairs and preserves the car's value over time.
Specialty Detailing Services
Sometimes we need more than a routine wash.
Specialty detailing services can include the use of iron removers for the wheels and tires or glass cleaner for streak-free clarity.
Quick detailing is perfect for a mid-week boost, focusing primarily on appearance and fast maintenance.
Whether it's a weekly exterior detail or a deep interior detail, every service is a step toward preservation and an impeccable aesthetic.
How long does it take to detail a car?
A quick interior detail might take two hours, while a comprehensive exterior detail might take up to two days. If the vehicle is detailed regularly, a small coupe, hatchback, or sedan will take four hours or more. It will take at least seven hours for extra-large trucks and minivans.
Why does detailing take so long?
If you're going to do it yourself, it's likely to take longer than if you got a professional car detailer to do so because professionals are more experienced and better equipped. Size is also a key factor. It takes longer to detail trucks and large SUVs than it does to detail compact cars.
How many times can you detail a car?
The frequency that you should get your car details varies by how much wear and tear you put on your vehicle and how often you wash and wax it, but most experts recommend you have it done 2 to 3 times a year, or once every 4 to 6 months.
How often do you detail your Car?
Or does someone else do it for you?
What involves your detailing Rhythm? We would love to hear everything about it, whether it will be in the comments or via Mail, till then see you next time when it says again…

Fraud is on the rise in the real estate industry – know how to protect yourself and your customers. Below are examples of the type of fraud the real estate industry is seeing, best practices on how to avoid getting scammed, what to do if you suspect a real estate scam, and resources.
- What are fake seller scams? Someone posing as the owner of a property tries to get a listing, a contract, and a closing where they can steal funds for a property they do not own. They usually supply fraudulent identification and will typically use the internet and telephone to close the transaction. If they are identifying themselves as authorized representatives of companies that own the property, they tend to use fake emails instead of corporate emails and will try to sign listing agreements with the name of the company rather than the name of the individual who is authorized to represent the company to avoid getting caught.
- What are vacant lot scams? This is a form of a fake seller scam. Typically, the victims of fraud live outside the United States and own vacant properties without mortgages. Often, the properties are owned by LLCs. A "seller" will reach out to a real estate agent to list "their" property, or they will identify themselves as authorized representatives of the companies or corporations that actually do own the land. They will usually want to rush a deal and will generally not meet with their agents in person.
- How to avoid getting scammed?
- Do your due diligence as soon as possible.
- Independently verify whether there is a mortgage.
- If you are considering skipping title insurance, consult with an attorney first to fully evaluate the risk.
- Check the local property appraiser's website to see whether the individual or entity claiming to own the property actually does own it. If you see that there were "errors" in recording the deed, but the seller is assuring you it was just a mistake, this should be a big red flag.
- Contact the true owner to verify they are actually selling the property, the price, and to whom. Do not rely on the contact information you were given – talk to the neighbors, search online for additional contact information (phone, email, social media, addresses). Consider sending a letter, with tracking and delivery receipt, to the true owner. That said, be mindful of your obligations under the Code of Ethics.
- If you are working with a buyer and the seller is working with an agent, talk to the listing agent. Ask whether they know the seller personally, and if not, ask how they met and how they have been communicating. If all communications have been by email without any prior relationship, be on alert.
- This article by The Fund® provides examples of real scams and advice on how to verify the true owner and their intentions to sell.
- Be alert when documents are signed outside your presence. Remember, you should always exercise caution in closing transactions where you do not personally know the seller or where the seller is executing a deed outside of your presence. If the seller executes and notarizes documents abroad outside of your presence and sends them to your office via an international postal service, be on high alert.
- Carefully review all signatures. Cross-reference signatures with government-issued documents. Verify that passports are valid with government authorities. Get a second form of identification.
- Consider using RONs. If the seller insists on a remote closing, but refuses to use a Remote Online Notary, it might raise a red flag.
- Check for forged notary blocks.Notary stamps should clearly display the name of the notary, their commission number, and the date their commission expires. Verify the notary through the relevant government agency. Be on high alert of any of the notaries that The Fund® has flagged are listed on closing documents or deeds, as it might indicate a forged notary block.
- Proceeds should only be disbursed to the person in title. Make sure you consult with the title company and an attorney if you think the situation merits an exception.
- Do your due diligence as soon as possible.
- What are commission advance schemes? Fraudsters are posing as real estate agents and are trying to obtain commission advances under those fake identities. Sometimes the fraudsters hack into agents' emails and provide details on deals that are in the works and sometimes they create fake deals.
- How to avoid getting scammed?
- If you are a broker, consider whether you allow commission advances. Keeping in mind that all business decisions must always be made unilaterally and independently, brokers will want to weigh the pros and cons of allowing agents to seek commission advances.
- If you are an agent, give your broker written instructions on how to handle commission advances. If your broker allows commission advances, email your broker about how you want your broker to handle any requests for commission advances. For example, if you know that you will never request a commission advance, tell them. That way if they do get a request, it will raise red flags. Likewise, if you want your broker to get written confirmation from you before sharing any information with commission advance companies, tell them that.
- Identity theft protections. Even if you have not yet been the victim of a scam, you can request that the credit reporting agencies "freeze" or "lock" your credit. This blocks access to your credit report and prevents anyone from opening an account in your name. Visit Experian, TransUnion, and Equifax online to do so. These are free services that usually have options to upgrade to more robust credit monitoring services.
- Monitor your records with DBPR. Check the DBPR records frequently to make sure your contact information is accurate and that it has not been changed. Sometimes, fraudsters will change your information with DBPR so that they can then pose as you with other agencies.
- Practice good password hygiene. Make sure your email and any document management services have strong passwords that you change frequently. The first point of entry for most scammers is your email – once they get in there, they can take over deals and your identity.
- Use multi-factor authentication. This requires that you prove to the service that you are trying to access, like email, that you are who you say you are.
- Monitor your accounts with MIAMI REALTORS®. Always feel free to reach out to us (live chat, email, or call us at 305.468.7000) with any questions or concerns about your account, like verifying the email and telephone numbers we have for you on file.
- What are fake landlord scams? Usually, someone who claims to be the landlord or owner of a property posts a fake rental listing online.
- How to avoid getting scammed?
- Monitor third-party websites for your listings. If you are the listing agent for a rental, search third-party websites like Craigslist, Facebook Marketplace, Apartments.com, and Google with the property address. If you see your listing anywhere it should not be, contact the website admin immediately to take down the fake listing. You should also contact MIAMI MLS at email@example.com.
- Read the FLORIDA REALTORS®' article, "Fake Landlord Scam."
- Contact law enforcement ASAP – local, county, and the FBI. If the property is located in a municipality, then first contact local law enforcement. Take that case number to the county law enforcement, where applicable, so they are also aware of the issue. See the "Resources" section below on who to contact.
- Email the MIAMI MLS at firstname.lastname@example.com with as much detail as possible (listing number, individuals involved, details about the transaction).
- Watch the webinar we hosted on February 16, 2023, and review the slides

Week 7: Distributing sleep questionnaire, analyzing data
April 19, 2024
Welcome to the eighth post for this project. In the previous post, I delved into an explanation of both my progress in the research paper and the progress made in the methodology. In this post I will mainly discuss the progress I have made in the data collection this week.
In the previous post, I explained the progress being made in the methodology section of the research paper. The methodology section discusses the questions that compose the sleep quality questionnaire and the method of how the responses are analyzed. The questions are categorized under the following: sleep duration, restoration after sleep, sleep efficiency, sleep regularity, sleep environment, and lifestyle. These factors listed have been determined from my research of published sleep quality studies. I score the answers to a subject's submitted response of the questionnaire on a scale of 1 to 4 points per question or a scale of -1 to -4 points per question depending on the question and what its answers imply for sleep quality. The points get added up and a score representing the subject's sleep quality is determined. The sleep quality scores of several subjects that have taken the sleep questionnaire will be compared and correlated to the light pollution indexes of their reported regions. After doing so I will look for a trend that indicates a correlation between light pollution index and the sleep quality score.
Last week I distributed my questionnaire to 11 subjects. I have distributed it to 6 more subjects this week. I plan on distributing it to more subjects this weekend and reaching at least 30 subjects by the end of next week. I have conducted an analysis of my current responses and realized that there does not seem to be a significantly strong correlation between sleep quality and light pollution index of their reported regions; however, my sample size is still relatively small and I need more subjects to make a sufficient analysis.
As mentioned in the previous post, I resort to using publicly available data from NASA VIIRS which is viewable on the website lightpollutionmap.info, the most recent data being from December 2023. The light pollution index is representative of general radiance in the region, and the unit for radiance is watt per steradian per centimeter squared. The average light pollution index of the data I currently have is roughly 70.0 on a scale of 0.10 to 150.
As I continue to collect data (sleep quality scores from subjects) this week and next week, I will be recording them and looking for any noticeable discrepancies between the data reported from the subjects living in areas of noticeably different indexes of light pollution. In addition to the data collection, which is currently the majority of my work in this project at this point in time, I will continue to polish my methodology section and finalize most of the sections of the research paper that I have been working on for the past few weeks.
Thank you for reading this post, and I look forward to keeping you updated on my progress.

This article reviews literature available in relationship to youth tobacco prevention through education and use of a video creation by the students. The study also incorporates the Cone of Experience in relationship to the students retaining knowledge from the process of creating short video clips related to the effects of tobacco use in youth. Data for this study was collected via pre- and post-test questionnaires of youth students attending a Boys & Girls Club of America in Southeastern United States. Various descriptive statistical analyses were utilized to compare the results of the pre- and post-tests to determine how much students learned from educational presentations and video creation in relationship to tobacco prevention.
Keywords: Tobacco Prevention, Youth with Disabilities, Cone of Experience, Video Experimental Model, Risk taking Behavior
Many research efforts have been presented in relationship to adolescents with learning disabilities who misuse drugs and abuse illegal substances. There is a lack of research available that details the misuse of tobacco products by youth and adolescents that suffer from learning and mental disabilities. In this study, the Cone of Experience was utilized as a method for educating adolescents on the risks and complications of using tobacco related products.
Previous research has indicated that at-risk populations are more at risk for increased tobacco use [1,2]. Factors attributing to at-risk populations include those of minorities, lower socioeconomic status, lack of education, and participation from parents. Additionally, there is a known connection between tobacco and substance abuse with adolescents with learning disabilities [3-5]. Edgar Dale's [6] Cone of Experience is of importance to this study because it has been proven through previous research to assist in the retention of information presented through audio and visual materials. Moreover, those who participate in experiential activities are known to retain even more of the knowledge gained according to the Cone of Experience [6]. After reviewing the previous literature and research available, a research gap presented itself. This research effort intended to reach at-risk adolescent populations, many of which are likely to have learning disabilities, by utilizing experiential educational presentations and projects to inform them about tobacco products and the risks associated.
The data for this study was collected at a Southeast Alabama Boys and Girls Club of America (BGCA). Unfortunately, the state of Alabama is recognized as not having favorable rankings in relationship to tobacco usage. As of 2017, the national rate of tobacco usage in adults was 17.1% but 20.9% for Alabama. In a 2015 study of high school students, they indicated participation in the following activities at least once in the last 30 days: 14% of high school students in Alabama smoked cigarettes compared to the national average of 10.8%; 24.5% used e-cigarettes or vapor products while the national average was 24.1%; and 12.5% of Alabama students reported using chewing tobacco, snuff, or dip while the national average was only 7.3% [7]. These statistics prove that adolescents residing in Alabama are more likely to participate in the usage of tobacco related products in comparison to adolescents nationwide. It also indicates that there is a need for preventative educational measures to be implemented within at-risk populated areas in Southeast Alabama territories.
There are numerous research studies available in relation to substance use by adolescents with learning disabilities [2-5,8-12]. Per the University of Maryland Medical Center [13] substance use is the ongoing utilization of liquor, drugs, or the abuse of a drugs prescribed by a physician, or drugs sold directly to a consumer without a prescription with harmful results. For purposes of this research paper, tobacco products are also going to be considered as a substance. Tobacco and alcohol use have played a significant role in the declining health of the general population, as well as paving a path for substance addiction later in life [4].
There are many factors that could lead to addiction of substances in youth: learning disabilities, depression and violence [12], psychological disorders and poverty levels [4], chemical dependency, race, socioeconomic status, age, and gender [2].
Adolescents with learning disabilities tend to partake in substances frequently as an outcome of their surroundings. Some of those factors are due to trying to handle their problems or conducting themselves better in school, peer pressure, types of abuse, others in the home using drugs, hereditary genetic vulnerability, intellectual disorders, and the availability of drugs [14]. The CDC also recognized lower pay or schooling, lack of talent to endure authority to utilizing tobacco, lack of assistance or participation from parents, the cost of tobacco products, little self-regard, and exposure to tobacco advertising to be factors increasing tobacco use [1]. Partaking in the use of substances leads to risky behaviors and maybe even criminal acts.
The Center for Disease Control and Prevention (CDC) described youth with a learning disability as an adolescent struggling in one or more of their academic studies and their standard intellect is not altered [1]. Many researchers have investigated connections between learning disabilities and substance abuse over the years. It has been found that as much as 70% of chemically dependent adolescents have also been diagnosed with a learning disability [12].
Beitchman, et al. [3] completed a two-part research study to determine if youth between the ages of 12-19 had learning disabilities and then were reassessed after they turned nineteen years of age to determine if they had any substance abuse disorders. It was determined from Beitchman, et al.'s [3] study that participants with a learning disability were more likely to develop a substance abuse disorder or a psychiatric disorder compared to those students without a learning disorder. Those with a learning disability were found to be three-times more likely to be at risk of substance use disorders when behavioral issues and family history were also factored into the data [3]. This study was comprised of primarily Caucasian participants presenting a need for this study to be replicated on a more diverse population.
Another study that focused heavily on connections between substance use and substance abuse with youth having learning disabilities, specifically Attention Deficit Hyperactivity Disorder (ADHD), was published by Molina and Pelham [5]. They surveyed a group of youth enrolled in a summer treatment program for youth with ADHD and discovered that adolescents with just a learning disability were less and not both likely to drink heavily but were more likely to have tried cigarettes [5]. The participants with ADHD who had higher IQs and higher levels of academic achievement were found to be more likely to try cigarettes, smoke daily, and try their first cigarette or alcoholic drink at an earlier age [5].
In a study completed by Emerson and Turnbull [4], it was determined that the prevalence of alcoholism is lower among youth with intellectual disabilities. Alternatively, in the same study by [4] it was also found that youth with mild intellectual disabilities have higher rates of both smoking and alcohol use. Children with intellectual disabilities in this research effort also reported being a current smoker at higher rates than that of non-intellectually disabled children [4].
One specific research study was completed with the intention of determining whether substance abuse treatment would be less effective for patients suffering from a learning disability [12]. This study compared substance abuse treatment outcomes between young people with and without learning disabilities in Massachusetts. It was determined by this research study that those suffering from learning disabilities had higher rates of adverse post-treatment outcomes, such as incarceration rate and substance re-use [12].
For this research study, Edgar Dale's Cone of Experience will serve as the theoretical framework to help us determine the success of our educational presentations and activities in relation to tobacco prevention. Edgar Dale regarded his Cone of Experience as a tool to show progression of concrete to abstract learning experiences [15]. The Cone of Experience theory references that if you experience something either by reading, hearing, seeing, saying, doing or combination of those acts, then you will retain information by greater percentages based on the activity associated [6]. Dale incorporated the influences of Bruner's [16] modes of learning into his Cone of Experience, which categorized the layers of activity in the Cone into three modes: enactive (i.e. learning by doing), iconic (i.e. learning by observation), and symbolic experience (i.e. learning by abstraction). Ultimately, it is theorized that learners will retain more information by doing than sampling hearing, reading, or observing—this is most commonly recognized as experiential learning [17].
Within the Cone of Experience, there are six primary levels to consider and within each of those levels there are different ways of presenting information to individuals. Percentages of retention are associated to each of the six levels of activities. Within the top peak of the Cone, is reading. If you read something, you are said to retain approximately 10% of the information according to Dale's Cone of Experience [17]. This area of the cone is directly connected with hearing information presented and accounts for approximately 20% of retention. Reading would be considered a symbolic experience, while listening would be an iconic experience if utilizing Bruner's [16] modes of learning. The desired learning outcomes for someone who has either read or listened to information presented on a topic that they be able to define, describe, list, or explain what was just experienced [17].
The second tier of the Cone accounts for watching still or moving pictures, viewing exhibits, or watching demonstrations. In watching still or moving pictures, 30% retention is expected from seeing something. Participants will likely retain 50% of information that is viewed as an exhibit or demonstration as they've experienced a combination of seeing and hearing the information presented [6]. Demonstrating, applying, and practicing are the desired learning outcomes within this tier [17]. It is within the top two sectors of the Cone that learners are considered to be passive learners [6]. All of these areas would fall into iconic experiences if utilizing Dale's [6] adaptation of modes of learning from Bruner [16].
Finally, within the third tier of the Cone, participants would be experiencing information by participation in hands-on workshops, role-playing situations, simulation of real experiences, or direct purposeful experiences. It is within this bottom tier of the cone that the majority of information is retained by either a combination of saying and writing (70% retention rate) or by doing a task (90% retention) [17]. All of these enactive activities [16] lead to projected learning outcomes of analyzing, designing, creating, and evaluating [17].
By utilizing Edgar Dale's [6] Cone of Experience theory as the framework for this study, the researchers' developed an educational seminar related to the risks and complications of using tobacco related products for adolescents. By developing educational activities based on the Cone of Experience, the researchers intend to report on the student retention of the information presented to them through the experiential learning activities. According to Dale's [6] Cone of Experience, students should retain approximately thirty-percent of what they saw and heard in the presentation.
Also, within the seminar, students participated in the creation of a video commercial focused on the prevention of youth tobacco usage. This would allude to the students retaining roughly ninetypercent of the information they learned through their efforts of both saying and doing the activity themselves according to the Cone of Experience [6]. By using audiovisual materials, it is proposed that those materials will "provide a concrete basis for learning concepts, heighten students' motivation, encourage active participation, give needed reinforcement, widen student experiences, and improve the effectiveness of other materials" [15].
Therefore, based on previous research and the Cone of Experience [18] model, the study's aim is threefold: (1) examine participants' retention of information, (2) examine altered perceptions of participants, and (3) examine participants' change of anticipated behavior as related to tobacco products following an educational seminar.
The purpose of this study was to examine the likelihood of adolescents to consume tobacco products subsequent to an educational seminar on the risks and complications of using tobacco related products. Therefore, the target population for this study was adolescent children under 18 years of age because they are more likely to be exposed to peer pressures related to trying tobacco products, alcohol, or other drugs [19]. Boys and Girls Clubs of America (BGCA) serve youth ages 6-18 and are focused towards providing educational and youth development opportunities to low income children and adolescent populations [20]. In many situations these children are considered at-risk populations due to the BGCA club placements being located primarily in low-income, minority populated areas. Within their programing they strive to "empower kids to lead healthy and productive lives with life-enhancing programs" [21].
As the purpose of this study directly aligned with the mission of the BGCA, the researcher obtained the final sample for this study from a small-town Southeastern Alabama Boys and Girls Club. The advantage to this sampling method is that all data was collected within the same club, providing the ability to control for variables such as geographical region, socioeconomic status, and the environment of the small-town controls for similar exposure to tobacco advertisements for the respondents. Therefore, a purposive sampling method was employed to obtain responses from adolescents between the ages of 6-17 from a Southeastern Alabama Boys and Girls Club.
The primary objective of the current study was to examine the intended tobacco related behaviors of adolescents following an educational seminar. Therefore, the researchers utilized the recommendations of [22] in development of an instrument. First, a thorough review of relevant literature and theoretical frameworks were utilized to specify and define various constructs. Next, a deductive approach was applied to produce the necessary items of the instrument. Finally, a panel of experts evaluated the content validity of the instrument. Two scholars were asked to conduct a content analysis, while two practitioners were asked to assess the face validity. Overall, the review of the content relevance, readability, and clarity of the content was adjusted based on the recommendations of the panel to provide the final instrument for the study.
The pre-test asked a set of four questions related to demographics. Specifically, those questions asked their age, gender, academic grade, and race or ethnic grouping. This information was utilized to provide a demographic profile of the respondents. Eight questions focused on their awareness and perception of tobacco products and health complications caused by using tobacco products. The responses within these questions were used to gain a better understanding of the respondents' retention and perception. Two additional questions on the survey inquired about the students' prior use of tobacco products and their intent to use in the future. These responses were utilized to examine the likelihood of change in the expected behaviors of the respondents.
A request to the Institutional Review Board (IRB) to conduct this study was submitted and approved. The students who participated in the study were granted parental permission prior to them taking the survey and participation in the activities affiliated to the research study. To properly evaluate the intervention program and achieve the overarching purpose of this study, it was necessary to employ a pre- and post-test. Therefore, at the beginning of the educational seminar the participants were given the pre-test. The intention of the pre-test was to gain a baseline knowledge level of the students in regard to their educational awareness of tobacco related products. The entire survey consisted of fourteen questions and took the group of participants roughly 15-20 minutes to complete each time it was taken.
After the students completed the pre-survey, the same set of students were involved in an educational presentation on tobacco products and the health complications as a result of using tobacco related products. This consisted of a PowerPoint presentation and open dialog with students allowing them time to ask questions and become more knowledgeable about tobacco awareness and use prevention. Next, the group was tasked with creating an educational video commercial on tobacco awareness and prevention. At the conclusion of the presentation and their participation in creating the video commercial for tobacco awareness, the students then completed the same survey again in the form of a post-survey. The post-test served as a gauge for comparison to see how much the students learned throughout the educational presentation and their participation in the video commercial creation.
The data was analyzed and processed using SPSS Statistics 25 software. Based on the purpose of this study, a combination of descriptive statistical analyses was examined to provide a clear foundation of knowledge for practical application and future research. Descriptive statistics were used to create a demographic profile of the participants. To address the retention of information, change in perceptions, and anticipated behaviors of the respondents means were compared to adequately analyze the participants' preand post-test responses.
There was a total of 32 participants that took both the pre- and posttests and completed the two activities associated with the research study. The age of students who participated in the study ranged from 9 to 17 years of age, with the majority of participants being 9 years of age (36%) with 11-years of age being the next largest group (23%). Females (47%) represented the bulk of the participants; while the majority of the sample was reportedly in the 6th grade (23%). Additionally, 89% of respondents listed their race or ethnicity as being black or African American.
The BGCA students were asked what problems resulted from smoking tobacco products with the options for response being heart disease, cancer, stroke, asthma, and all of the above. Results showed that 40.6% of BGCA students who participated in the study realized that all of the choices listed were potential health problems as a result of using tobacco products in the pre-test (M=3.18), but 45.2% knew that all of the choices were potential health problems when taking the post-test (M=3.61). This indicates that our activities did increase the knowledge level of 4.6% of the students in regard to the potential health risks involved in partaking in tobacco related products.
A similar question was asked in regard to potential reactions of using tobacco related products. The students were given choices of yellow teeth, smelly clothes and hair, loss of taste and/or smell, trouble breathing while exercising, and all of the above. Pre-test results showed that 37.5% of the students believed that all of the above listed items were potential reactions caused by smoking tobacco products (M=3.18), while post-test results showed that 46.7% understood that all of those issues would result from smoking tobacco products (M=3.83). This showed an overall increase of 9.2% of the BGCA students recognizing the potential reactions of smoking tobacco products.
In comparing the pre- and post-test data results, it was clear that participants' perception of the dangers and consequences of using tobacco products changed as a result of participating in experiential learning activities was supported by this research study. The experiential learning activities that the BGCA student sample participated in did change their perception of the dangers and consequences of using tobacco related products. In the pre-test results, when students were asked "Do you believe e-cigarettes are harmful?" 58.1% said "yes," 16.1% said, "no" and 25.8% answered "I don't know" (M=1.67). After participating in our lecture and experiential learning activities, students responded to the same question in the post-test. The results in the post-test yielded a 76.7% response rate for "yes," 20% said, "no" and only 3.3% said "I don't know" (M=1.26). Overall, utilizing the descriptive statistics for the question, "Do you believe e-cigarettes are harmful?" shows an 18.6% increased rate of change. This specific question was of importance to us because teens in the United States are more likely to use e-cigarette products in comparison to traditional cigarettes [23]. To further the importance of education in regard to dangers of using e-cigarettes, teens who use e-cigarettes are more likely to transition to the use traditional cigarettes [23].
The next question asked of the BGCA students was, "Do you believe smoking leads to the use of drugs or alcohol?" Pre-test results of this question showed 59.4% of students said "yes" 12.5%, said "no", and 28.1% were not sure and responded, "I don't know" (M=1.68). Post-test results showed that 68.8% of students learned from the educational presentations and experiential learning activities that "yes" smoking tobacco products does lead to the use of other drugs and/or alcohol products. 12.5% still responded with "no" to the same question and 18.8% were still unsure and responded, "I don't know" (M=1.50). This indicates an increase of 9.4% of students recognizing that smoking tobacco related products can lead to the use of other drugs and alcohol products as a result of our educational presentation and experiential learning activities.
The final question asked of the participants in relationship to change of perception, was "How strongly do you agree with the statement, "All tobacco products are dangerous?". Pre-test results indicated that 71% of participants said they either agreed or strongly agreed that tobacco products were dangerous (M=1.80). In the post-test results, the percentage associated to either agree or strongly agree increased to 90.3% (M=1.45). Overall, this was a significant improvement in regard to changing the adolescents' perception of the dangers related to tobacco products.
The third hypothesis statement: "students will be less likely to use tobacco related products after participating in the experiential learning activities of this study" was also supported by this research study. BGCA students that participated in our experiential learning activities were asked the question in both the pre- and post-test, "Do you intend to use any tobacco products in the future?" Pre-test results showed that 78.1% of participants said "no" they would not use tobacco products, while 21.9% said "I don't know" (M=2.21). After participating in the different experiential learning activities, posttest results indicated that the percentage of students who said "no" increased to 85.7% (M=2.14), showing a 7.6% change in likelihood to not use tobacco related products.
Knowledge retention through experiential educational activities, altering the perception of risk, and anticipating the behaviors of adolescents in relationship to tobacco related products were the generalized objectives of this research effort. This research study utilized Dale's [6] Cone of Experience model in combination with experiential learning activities to educate students attending a local BGCA about tobacco related products and risks of usage. Additionally, this research effort was developed to decrease the likelihood of adolescent participants to partake in the usage of tobacco related products preventing them from becoming a gateway substance to alcohol and illegal drugs.
Results of the study provided that using the Cone of Experience to educate students on the health risks and potential ramifications of using tobacco products did aid in the retention of information presented to the students. Dale's [6] Cone of Experience illustrates the importance of effective communication and learning for younger populations to provide a foundation for permanent learning on a topic. This research showed through improved responses on the post-test that they did retain information presented and have a better understanding of the complications and risks associated with using tobacco related problems.
This research study also indicated that as a result of the educational presentations, students' perception of danger and risk associated with tobacco products drastically changed from the pre- and posttest results. Students had a better understanding of risk associated to using tobacco related products after our educational presentation and activities in comparison to what they knew beforehand. It can be assumed that students entering into the experiential learning activities had little to no initial perception of the dangers and consequences associated with tobacco product usage. The experiential learning activities and presentations conducted at the BGCA in Southeast Alabama provided the foundation for the students' perceptions of tobacco products, their dangers and tobacco serving as a gateway to using other substances. It is known that BGCA target at-risk adolescent populations which are more likely to have substance abuse disorders [2-5]. Knowing that the results from this research study provided a positive impact towards changing the adolescents' perception of tobacco related products, the risks associated with usage, and their beliefs of tobacco leading to other drugs or alcohol, practitioners would be wise to employ the Cone of Experience framework in the future.
Perhaps the most important information that can be gathered from the results of this research study indicates that students are less likely to partake in the use of tobacco products after experiencing educational learning activities. Tobacco usage has played a significant role in the declining health of the general population, ultimately paving the way for substance addictions later in life [4]. By educating adolescent populations living in an area prone to tobacco product usage, any positive change in their behaviors at an earlier age will improve their overall health and well-being for years to come. Therefore, practitioners should be encouraged to incorporate activities of this nature more frequently and abundantly. Additionally, educators within the public and private sectors should offer activities to assist with the reinforcement of such foundational knowledge to prevent tobacco usage.
The major limitation of the study is the purposive, non-probability sampling method, since results cannot be generalized to the larger population. A probability sampling method would be beneficial to employ in future studies of similar nature. Another limitation is the age of the majority of respondents. The majority of respondents were reportedly nine years old, and although the researchers believe the educational seminar was beneficial for them to participate in, their comprehension of answering a survey may be too advanced. Future studies should consider limiting the study to participants 11-12 years of age or older, as this was the intended target population due to this age demographic being more exposed and susceptible to peer pressures of experimenting with illegal substances such as tobacco, alcohol, or other drugs. It may also be of interest for this study to be replicated to address other health related issues impacting adolescents: sex education, alcohol awareness, marijuana or other drug usage, proper seatbelt usage, and texting while driving are a few topics to be considered.
There is valuable information to be derived from this study that could apply to various populations: educators, health care professionals, social workers, and child care workers to name a few. Educators and child care workers could benefit from this information as they are in direct contact and have significant influence on adolescent populations. Utilizing similar presentations and projects in classroom environments could assist in decreasing the likelihood of partaking in activities that are considered dangerous or risky. To help with the promotion of permanent learning, teachers should help students identify needs and set goals related to those needs. Using Dale's [6] Cone of Experience, these professionals can tailor the learning experiences to be meaningful and appropriate to the different developmental stages of the students. Health care professionals and social workers can employ similar program offerings to disperse information to their patients and clients to help reduce the probability of children and adolescents using in tobacco related products or participating in other risky behaviors and activities.
Throughout this research effort, it is evident that there is a need for effective educational presentations related to tobacco prevention and substance abuse for populations that are considered at-risk. Specifically, there is a need for special programs to be created for those living with intellectual disabilities and to develop health promotion activities to assist with positive change related to retention, perception, and behavioral choices [4]. Future research efforts could easily use this study as a foundation to address other areas of concern for adolescents for the betterment of their overall health and wellbeing.

The Myanmar Navy (Burmese: တပ်မတော် (ရေ); [taʔmədɔ̀ jè]) is the naval warfare branch of the armed forces of Myanmar. With 16,000 personnel on duty, the navy operates more than 227 vessels.[3] Prior to 1988, the navy was small, and its role in counter-insurgency operations was smaller than those of the army and the air force. The navy has since been expanded to take on a more active role in defense of Myanmar's territorial waters.
The naval arm of the Royal Armed Forces consisted mainly of shallow draft river boats. Its primary missions were to control the Irrawaddy River, and to protect the ships carrying the army to the front. The major war boats carried up to 30 musketeers and were armed with 6- or 12-pounder cannon.[4] By the mid-18th century, the navy had acquired a few seafaring ships, manned by European and foreign sailors, that were used to transport the troops in Siamese and Arakanese campaigns.
The Arakanese and the Mon, from maritime regions, maintained more seaworthy flotillas than the inland riverborne "navy" of the Royal Burmese Army.
Founding and the Second World War
Burma separated from British India in 1937 and thereafter became responsible for her own local naval defence. It was decided that a naval volunteer reserve force should be formed to implement this responsibility and so provide a local force for the naval administration and defence of the ports and coast of Burma in time of war.
On the recommendation of Vice Admiral Sir James Fownes Somerville, then Commander-in-Chief, East Indies, Lieutenant Commander Kenneth Sidebottom Lyle from Royal Navy was sent to Burma and arrived in Rangoon in June 1939, commissioned to form the volunteer reserve force and to be appointed Naval Office-in-Charge, Rangoon, on the outbreak of war.
On 6 September 1940, Burma Royal Navy Volunteer Reserve was officially formed under the Burma Act XV, 1940.[5] The Burma R.N.V.R was placed under the operational orders of Vice Admiral Sir Herbert Fitzherbert, commanding the Royal Indian Navy, but retains its own identity and its own administration under the Government of Burma.
Burma R.N.V.R, although very small, played an active part in Allied operations against the Japanese during the Second World War. By 1 December 1945, the Royal Navy has been withdrawn and the Burma R.N.V.R assumed all naval responsibilities on the coast and waters of Burma.[6]
Burmese independence
In December 1947, the Union of Burma Navy was formed with 700 men mostly from Burma R.N.V.R. The fleet initially consisted of a small but diverse collection of ships transferred from the Royal Navy under the arrangements made for Burma's independence in January 1948. It included the UBS Mayu, an ex-Royal Navy River-class frigate, and four Landing Craft Gun (Medium).[7] British Defense Ministry sold with the original 25-pounder guns on naval mountings and Oerlikon 20mm cannons which were reinstalled later.
In 1950 and 1951, the United States provided 10 coast guard cutters (CGC) under the Mutual Defense Assistance Program (MDAP). The Myanmar Navy played an important part in the government's fight against the ethnic and ideological insurgent groups which threatened the Union Government in its early days. The Myanmar Navy performed both defensive and offensive roles, protecting convoys, carrying supplies, ferrying troops and giving much-needed fire support. It was instrumental in relieving the port city of Moulmein, which was captured by Karen insurgents in 1948, and the Irrawaddy Delta town of Bassein. Although one armed patrol boat defected to the Karen insurgents, throughout the turbulent years of post independence in Myanmar, the navy was largely unopposed and maintained control over Myanmar's crucial inland waterways.[8]
In 1956 and 1957, the Burmese government acquired five 50-long-ton (51 t) Saunders-Roe Dark-class convertible motor torpedo/motor gunboats,[9] followed by an 1,040-long-ton (1,060 t) Algerine-class minesweeper in 1958 from the United Kingdom.[10] In the late 1950s and early 1960s, the United States sold the Burmese Navy six PGM type coastal patrol craft and seven CGC-type patrol boats.[11] In 1958, Myanmar's Navy took delivery of 10 Y-301-class river gunboats from Yugoslavia, followed by 25 smaller Michao-class patrol craft.
Efforts were made to produce locally made naval vessels with assistance from Yugoslavia. In 1960, the Myanmar Navy commissioned two 400-long-ton (410 t) Nawarat-class corvettes. Their armaments include 25-pounder field gun and 40 mm Bofors anti-aircraft gun.[12] Myanmar shipyards also built a number of smaller patrol craft and a number of landing craft. Landing craft and auxiliary ships are usually armed with Oerlikon 20 mm cannons, 40 mm Bofors anti-aircraft guns and heavy machine guns.[13] In the mid-1960s, the Myanmar Navy took delivery of ex-US Navy 640-long-ton (650 t) PCE-827 class[14] corvette and a 650-long-ton (660 t) Admirable-class minesweeper, both of which were commissioned in the mid-1940s.
Although it expanded rapidly during the 1950s and 1960s, the navy was unable to keep pace with loss or deterioration of older vessels in the 1970s. In 1978, the United States provided the Myanmar Navy with six small river patrol craft.[15] A naval replacement program was initiated by BSPP Government in 1979.
In 1980, the navy acquired six Carpentaria-class inshore patrol boats from Australia followed by three 128-ton Swift-type coastal patrol boats from Singapore and three 385-ton Ospery-class offshore patrol vessels built in Denmark. The Osprey and Swift-class boats have a range of 4,500 and 1,800 miles (7,200 and 2,900 km), respectively, and were armed with Oerlikon 20 mm cannons and 40 mm Bofors anti-aircraft guns. In the early 1980s, Burmese naval shipyards built three 128-ton PGM type patrol boats based upon US PGM-class patrol boats. Each boat was armed with two 40 mm Bofors anti-aircraft guns and two 12.7 mm heavy machine guns.
The Myanmar Navy purchased six missile escort boats and ten submarine chasers from China. Since 1998, the navy has built two 77 m (252 ft 7 in) Anawrahta-class corvettes (771 and 772) and four fast attack craft (551-554).
In 2008 a naval encounter took place between the Bangladesh Navy and the Myanmar Navy. The confrontation was a direct result of the Myanmar Navy allowing companies to drill for natural gas and oil in a disputed area of the Bay of Bengal.[citation needed]
May 2008 Cyclone Nargis
As many as 25 Burmese naval ships may have been sunk in the storm caused by Cyclone Nargis in May 2008, while an unknown number of naval personnel and their family members were killed or are listed as missing.[16] The Network for Democracy and Development in Thailand reported that 30 officers and 250 Burmese naval personnel were declared missing, while 25 vessels were destroyed by the cyclone in three naval regional command centres: Panmawaddy Regional Command on Hainggyi Island; Irrawaddy Regional Command; and Danyawaddy Regional Command in Sittwe in Arakan State.
As part of international engagement of the US with the Myanmar's armed forces, the USS Bonhomme Richard (LHD-6) visited Myanmar in early 2013.[17]
In 2014, the Myanmar Navy began its annual 'Sea Shield' combined fleet exercise in the Bay of Bengal and the Andaman Sea. The annual manoeuvres usually involved live-fire exercises by several of the Myanmar Navy's strategic vessels.[18]
The navy participated in the Indian and Myanmar Navy Exercise 2018, held in the Bay of Bengal. On the Burmese side, vessels included the Kyan Sittha-class frigate UMS Sin Phyu Shin (F-14) and offshore patrol vessel UMS Inle and on the Indian side, vessels included anti-submarine warfare corvette INS Kamorta, Shivalik (Project 17)-class frigate INS Sahyadri, and a Type 877EKM Kilo-class submarine, along with one helicopter and two advanced aircraft.[19] In September 2019, Myanmar Navy's UMS Kyan Sittha participated in the first US-Asean Maritime Exercise (AUMX) to improve disaster management and maritime cooperation in the region.[20]
The navy has maintained relationships with regional navies. It has hosted navies from the region such as the Royal Australian Navy, the PLA Navy and the Indian Navy.[21][22][23] Likewise, the navy's ships have visited countries in the region including Vietnam, Thailand and Singapore.[24][25]

The Myanmar Navy formed a naval infantry battalion of 800 men in 1964, and a second battalion in 1967.[citation needed] They battalions traditionally are deployed mainly in the Arakan, Tenasserim, and Irrawaddy delta coastal regions primarily to assist in the army's counter-insurgency operations (COIN).[citation needed]
The Myanmar Navy Sea, Air and Land (SEAL) Teams, commonly known as Myanmar Navy SEALs (တပ်မတော် (ရေ) အထူးစစ်ဆင်ရေးတပ်ဖွဲ့) were probably formed in the early 2010s. The Myanmar Navy SEALs are particularly trained for special operation missions such as Hostage rescue, Counter-terrorism and Counter narcotic operations. The selection process and training curriculum is claimed be similar to United States Navy SEAL selection and training.[27][28][29]
Previously, Myanmar Naval air defence forces used Bofors 40mm & ZPU-2 AAA for naval bases.

The Myanmar Navy has undertaken a modernisation program since the early 2000s. It has added larger and more advanced ships, mostly by constructing them locally with foreign supplied equipment.[30]
The Myanmar Navy started its modernization program in 2001 in an attempt to replace older ships and equipment. In 2012, the navy took delivery of two Type 053H1-class frigates from China. These two ships were upgraded extensively. Upgrades included the replacing of HY 2 anti-ship missiles by C-802 missiles and installing new sensors. The first indigenous frigate, the Aung Zeya entered service in 2011 and took part in a joint exercise with Indian Navy ships off Visakhapatnam in early 2013. A second ship, Kyan Sittha entered service in 2012 and is the navy's first stealth frigate. The navy plans to build six indigenous frigates; combining Russian, Indian, Chinese, and Western weapons systems. These ships are equipped with Kh-35E anti-ship missiles, OTO Melara 76 mm Super Rapid Cannons, AK-630 6-barrel 30mm close-in weapon system (CIWS) and Chinese ASW rockets and torpedoes. Radars and electronic systems are mainly from Bharat Electronics of India. Myanmar acquired surface-to-air missiles and anti-ship missiles from China for its newly built frigates and OPVs. Myanmar Navy Shipyard built with Chinese assistance in the late 1990s is one of the most modern shipyards in the region. Many Burmese naval engineers underwent shipbuilding training in China and Russia.
In 2020, the navy acquired its first submarine, a Soviet era Sindhughosh/Kilo-class submarine, from India. The former INS Sindhuvir (S58) was refitted by Hindustan Shipyard Limited before the handover. Now renamed UMS Minye Theinkhathu, the submarine is to be used for training.[31][32] It was first seen publicly on 15 October 2020 as part of a naval fleet exercise ('Bandoola 2020').[33] The Indian Navy is going to assist in training Myanmar to operate the submarine effectively.[34]
On 24 December 2021, Myanmar Navy has commissioned its second submarine the UMS Minye Kyaw Htin, a type 35B Ming-class submarine from China.[35][36]
Between 2015 and 2017, the Myanmar Navy procured two Super Dvora Mk III patrol boats from Israel.[37] Next, under a US$37.9 million deal signed in March 2017, the Myanmar Navy received the advanced anti-submarine torpedo Shyena units from India.[38] Moreover, the Myanmar Navy acquired a new landing platform dock (LPD) from South Korea in 2019.[39]

What Happens When Plants Experience Stress?
In the world of botany, stress isn't just a human phenomenon; it's a crucial aspect of plant life too! Picture this: your garden plants are like little botanical superheroes, and stress is their training ground, shaping them into verdant champions of resilience. While it may seem counterintuitive, mild stress can actually be a catalyst for robust growth in many plant species. Just like how lifting weights builds muscle, subjecting plants to manageable stressors—like mild drought, nutrient deficiencies, or even gentle physical disturbances—can trigger a cascade of biological responses that fortify their defenses and spur growth. Think of it as plant boot camp! Scientific literature reveals that when faced with mild stress, plants activate a myriad of biochemical pathways, from the production of antioxidants to the synthesis of stress hormones. These responses not only help plants adapt to their environment but can also enhance their overall health and vitality. So, the next time you see your garden plants bravely weathering a dry spell or bouncing back from a pruning session, remember: a little stress might just be the secret to their green-thumb success.
Garlic Plants under Stress: Insights into Adaptation Mechanisms
Garlic (Allium sativum) is renowned not only for its culinary value but also for its medicinal properties and adaptability to diverse environmental conditions. However, the impact of stress factors such as cold conditions, wind, and predator attacks on the physiology and resilience of growing garlic plants remains a subject of scientific inquiry. This review article synthesizes current knowledge on the response mechanisms of garlic plants to stress, with a focus on whether stress induces heightened resilience or strength.
In natural ecosystems, plants encounter various stressors that can significantly influence their growth, development, and survival. Understanding how plants respond to stress is crucial for elucidating their adaptive strategies and enhancing agricultural productivity. Garlic is known for its hardiness and ability to thrive under adverse conditions. Investigating the response of garlic plants to stress can provide valuable insights into plant resilience and adaptation mechanisms.
Types of Stress:
Impact of Cold Conditions: Cold stress represents a major environmental challenge for garlic cultivation, particularly in regions with temperate climates. Studies have shown that exposure to low temperatures can trigger physiological responses in garlic plants aimed at mitigating the adverse effects of cold stress. These responses include the accumulation of osmoprotectants such as soluble sugars and proline, which help maintain cellular osmotic balance and prevent damage to cell membranes. Additionally, cold stress induces the expression of genes involved in the synthesis of antifreeze proteins and antioxidants, which protect plant tissues from freezing-induced injury. Overall, while cold conditions can temporarily inhibit growth, garlic plants demonstrate resilience through adaptive physiological mechanisms.
Response to Wind Stress: Wind stress poses another challenge for garlic plants, particularly during their early growth stages when they are more susceptible to damage. In response to wind-induced stress, garlic plants exhibit structural adaptations such as thicker stems and stronger root systems, which enhance their anchorage and stability in windy conditions. Moreover, wind stress stimulates the synthesis of secondary metabolites such as phenolic compounds and flavonoids, which act as antioxidants and strengthen cell walls, thereby reducing the risk of damage from oxidative stress. These adaptive responses enable garlic plants to withstand wind stress and promote their continued growth and development.
Predator Attacks and Defense Mechanisms: Predation by herbivores and pests represents a threat to garlic plants, potentially causing substantial yield losses if left unchecked. However, garlic plants have evolved an array of defense mechanisms to deter or mitigate the impact of predator attacks. One such mechanism is the production of sulfur-containing compounds, including allicin, which possess strong antimicrobial and insecticidal properties. These compounds not only repel herbivores but also inhibit the growth of pathogens that may exploit wounds inflicted by predators. Furthermore, garlic plants can emit volatile organic compounds (VOCs) in response to herbivore damage, signaling neighboring plants and attracting natural enemies of herbivores, thus enhancing indirect defense strategies. The activation of defense-related genes and the synthesis of defensive compounds constitute integral components of the plant's response to predator attacks, ultimately enhancing its resilience and survival. We all know the feeling – that looming deadline, the unexpected downpour on picnic day. Stress! It's the universal enemy, right? Not quite. Believe it or not, even our garden friends thrive on a little pressure. Take garlic, for example. This pungent powerhouse might seem tough as nails, but it actually needs a period of chilly weather to produce its best-flavored cloves.
Not All Stress is Beneficial for Garlic Plants:
How Wet Soil, Clay, and Extreme Temperatures Combine to Devastate Garlic Crops
Garlic Cultivation can be significantly impacted by unfavorable soil conditions and temperature extremes. Let us examines the detrimental effects of wet soil, clay composition, and extreme temperatures on garlic plants, highlighting how these factors act synergistically to cause plant death.
1. Wet Soil and Root Suffocation:
Garlic, like most plants, thrives in well-drained soil. Wet soil restricts oxygen flow to the roots, hindering cellular respiration, a vital process for energy production. This oxygen deprivation leads to root suffocation, stunting growth and potentially triggering root rot caused by anaerobic pathogens.
2. Clay Soils and Drainage Issues:
Clay soils have a high water retention capacity and poor drainage. This exacerbates the problem of wet soil, creating stagnant water around the roots. The dense clay particles also restrict root development, limiting the plant's ability to access water and nutrients from deeper soil layers.
3. The Temperature Factor:
Extreme temperatures, both high and low, can be detrimental to garlic. High temperatures can cause excessive water loss (transpiration) exceeding the plant's uptake capacity, leading to dehydration and wilting. Conversely, very low temperatures can freeze the water within the plant cells, causing them to burst and rupturing tissues.
Synergistic Effects: The combination of wet soil, clay composition, and extreme temperatures creates a perfect storm for garlic plant mortality. Wet clay soil further restricts oxygen flow when subjected to high temperatures, accelerating root suffocation. Conversely, during cold spells, the saturated clay soil freezes more readily, causing extensive cellular damage due to ice crystal formation.
The Human Connection: We're Not So Different After All
This might sound strange, but there's a surprising parallel between garlic and us humans. Just like a little stress can motivate garlic to produce its potent oil, moderate stress can actually be beneficial for us too. It can sharpen our focus, boost our immune system, and even enhance creativity. Think of it as the body's way of saying, "Hey, get it together! There's a challenge ahead!".
The Key is Balance: Don't Push Your Garlic (or Yourself) Too Far
Of course, too much stress is bad for everyone. If a garlic plant is exposed to a brutal, prolonged cold, it can become stunted and produce weak cloves. Similarly, chronic stress in humans can lead to a host of health problems. The key is to find the sweet spot – that manageable amount of stress that pushes us (or our garlic) to be our best selves.
The Spice of Stress: Why Your Garlic (and Garden) Needs a Little Pressure
In the vibrant tapestry of our gardens, one plant stands out for its pungent flavor, potent aroma, and remarkable ability to thrive under pressure: garlic. But what if I told you that stress isn't just an inconvenience for our green companions, but a secret ingredient for their success? Yes, you heard it right! Just like us humans, plants, including our beloved garlic, benefit from a bit of stress. So, let's delve into the garden and uncover why stress might just be the spice of life for our leafy friends.
First things first, why stress? Well, stress isn't always a villain in the story of plant growth; it can be a superhero, swooping in to save the day. When plants, like garlic, encounter stressors such as drought, poor soil, or pest attacks, they activate their defense mechanisms, triggering a cascade of biochemical responses. These responses often lead to the production of secondary metabolites, which are like the plant's own version of superpowers, helping them combat stress and survive adverse conditions. In the case of garlic, stress prompts the production of allicin, the compound responsible for its characteristic aroma and flavor. Allicin not only acts as a natural defense mechanism against pests and diseases but also contributes to the plant's resilience in challenging environments. So, that extra zing in your garlic might just be a testament to its battle scars and triumphs in the garden. But does stress really make plants stronger? Absolutely! Just like hitting the gym builds muscle strength, subjecting plants to controlled stressors can enhance their resilience and overall vigor. Research has shown that moderate stress can stimulate the production of antioxidants and other protective compounds, bolstering the plant's immune system and making it more adept at withstanding future challenges. Now, let's draw a parallel between the stress resilience of plants and our own lives as humans. Think about it: we often grow and thrive in the face of adversity. Challenges push us out of our comfort zones, forcing us to adapt, innovate, and emerge stronger than before. In a way, stress is the catalyst for our personal growth and development, shaping us into resilient beings capable of overcoming life's hurdles.
The resilience of garlic plants under stress conditions is attributable to a complex interplay of physiological, biochemical, and molecular responses. Despite the inhibitory effects of stress on growth and development, garlic plants demonstrate adaptive mechanisms that enable them to withstand adverse environmental conditions and ensure their survival. Future research endeavors aimed at elucidating the molecular basis of stress tolerance in garlic plants will contribute to the development of improved cultivars with enhanced resilience and productivity. Believe it or not, some stress can be a good thing for your garden! Plants, much like us, respond to challenges in their environment. Mild stressors like drought or minor nutrient deficiencies can trigger a phenomenon called hormesis, where the plant actually strengthens its defenses. Studies have shown this can lead to increased production of antioxidants, improved root growth, and even better resistance to pests and diseases [scholarly article on hormesis in plants]. It's like a workout for your plants, making them more resilient in the face of future threats. However, too much stress is counter-productive. Just like you wouldn't go from couch potato to marathon runner overnight, plants can't handle a sudden and harsh shift in their environment. So the key is finding that sweet spot of stress - a little challenge to keep them on their toes, but not enough to send them into meltdown. By understanding hormesis, gardeners can create a dynamic environment that fosters not just growth, but also hardiness in their beloved plants. |
