A railway electrification system supplies electric power to railway trains and trams without an on-board prime mover or local fuel supply. Electrification has many advantages but requires significant capital expenditure. Selection of an electrification system is based on economics of energy supply, maintenance, and capital cost compared to the revenue obtained for freight and passenger traffic. Different systems are used for urban and intercity areas; some electric locomotives can switch to different supply voltages to allow flexibility in operation.

Oklahoma City is on the I-35 Corridor and is one of the primary travel corridors into neighboring Texas and Mexico. Located in the Frontier Country region of the state, the city's northeast section lies in an ecological region known as the Cross Timbers. The city was founded during the Land Run of 1889, and grew to a population of over 10,000 within hours of its founding. The city was the scene of the April 19, 1995 bombing of the Alfred P. Murrah Federal Building, in which 168 people died. It was the deadliest terror attack in the history of the United States until the attacks of September 11, 2001, and remains the deadliest act of domestic terrorism in U.S. history.

The war entered a new phase with the unprecedented defeat of the Japanese at Battle of Suixian-Zaoyang and 1st Battle of Changsha. After these victories, Chinese nationalist forces launched a large-scale counter-offensive in early 1940; however, due to its low military-industrial capacity, it was repulsed by Japanese army in late March 1940. In August of 1940, Chinese communists launched an offensive in Central China; in retaliation, Japan instituted the "Three Alls Policy" ("Kill all, Burn all, Loot all") in occupied areas to reduce human and material resources for the communists. By 1941 the conflict had become a stalemate. Although Japan had occupied much of northern, central, and coastal China, the Nationalist Government had retreated to the interior with a provisional capital set up at Chungking while the Chinese communists remained in control of base areas in Shaanxi. In addition, Japanese control of northern and central China was somewhat tenuous, in that Japan was usually able to control railroads and the major cities ("points and lines"), but did not have a major military or administrative presence in the vast Chinese countryside. The Japanese found its aggression against the retreating and regrouping Chinese army was stalled by the mountainous terrain in southwestern China while the Communists organised widespread guerrilla and saboteur activities in northern and eastern China behind the Japanese front line.

During the first four days of the war, the general population of the Arab world believed Arab radio station fabrications of imminent Arab victory. On 9 June, Nasser appeared on television to inform Egypt's citizens of their country's defeat. He announced his resignation on television later that day, and ceded all presidential powers to his then-Vice President Zakaria Mohieddin, who had no prior information of this decision and refused to accept the post. Hundreds of thousands of sympathizers poured into the streets in mass demonstrations throughout Egypt and across the Arab world rejecting his resignation, chanting, "We are your soldiers, Gamal!" Nasser retracted his decision the next day.

Fearing the worst, the Romans began a major mobilization, all but pulling out of recently pacified Spain and Gaul. They even established a major garrison in Sicily in case the Seleucids ever got to Italy. This fear was shared by Rome's Greek allies, who had largely ignored Rome in the years after the Second Macedonian War, but now followed Rome again for the first time since that war. A major Roman-Greek force was mobilized under the command of the great hero of the Second Punic War, Scipio Africanus, and set out for Greece, beginning the Roman-Syrian War. After initial fighting that revealed serious Seleucid weaknesses, the Seleucids tried to turn the Roman strength against them at the Battle of Thermopylae (as they believed the 300 Spartans had done centuries earlier). Like the Spartans, the Seleucids lost the battle, and were forced to evacuate Greece. The Romans pursued the Seleucids by crossing the Hellespont, which marked the first time a Roman army had ever entered Asia. The decisive engagement was fought at the Battle of Magnesia, resulting in a complete Roman victory. The Seleucids sued for peace, and Rome forced them to give up their recent Greek conquests. Although they still controlled a great deal of territory, this defeat marked the decline of their empire, as they were to begin facing increasingly aggressive subjects in the east (the Parthians) and the west (the Greeks). Their empire disintegrated into a rump over the course of the next century, when it was eclipsed by Pontus. Following Magnesia, Rome again withdrew from Greece, assuming (or hoping) that the lack of a major Greek power would ensure a stable peace. In fact, it did the opposite.

Some developing countries that had seen strong economic growth saw significant slowdowns. For example, growth forecasts in Cambodia show a fall from more than 10% in 2007 to close to zero in 2009, and Kenya may achieve only 3–4% growth in 2009, down from 7% in 2007. According to the research by the Overseas Development Institute, reductions in growth can be attributed to falls in trade, commodity prices, investment and remittances sent from migrant workers (which reached a record $251 billion in 2007, but have fallen in many countries since). This has stark implications and has led to a dramatic rise in the number of households living below the poverty line, be it 300,000 in Bangladesh or 230,000 in Ghana. Especially states with a fragile political system have to fear that investors from Western states withdraw their money because of the crisis. Bruno Wenn of the German DEG recommends to provide a sound economic policymaking and good governance to attract new investors

In the winter and spring of 2011 a large outbreak of cryptosporidiosis occurred in Skellefte municipality, Sweden. This study summarizes the outbreak investigation in terms of outbreak size, duration, clinical characteristics, possible source(s) and the potential for earlier detection using calls to a health advice line. Methods: The investigation included two epidemiological questionnaires and microbial analysis of samples from patients, water and other environmental sources. In addition, a retrospective study based on phone calls to a health advice line was performed by comparing patterns of phone calls between different water distribution areas. Results: Our analyses showed that approximately 18,500 individuals were affected by a waterborne outbreak of cryptosporidiosis in Skellefte in 2011. This makes it the second largest outbreak of cryptosporidiosis in Europe to date. Cryptosporidium hominis oocysts of subtype IbA10G2 were found in patient and sewage samples, but not in raw water or in drinking water, and the initial contamination source could not be determined. The outbreak went unnoticed to authorities for several months. The analysis of the calls to the health advice line provides strong indications early in the outbreak that it was linked to a particular water treatment plant. Conclusions: We conclude that an earlier detection of the outbreak by linking calls to a health advice line to water distribution areas could have limited the outbreak substantially. Keywords: Early outbreak detection, Cryptosporidiosis, Syndromic surveillance, Cryptosporidium hominis Background The protozoan parasite Cryptosporidium is a major cause of gastroenteritis in humans worldwide [1]. At least 29 valid species of Cryptosporidium have been identified [2] and the two most common species infecting humans are Crypto- sporidium parvum and Cryptosporidium hominis [3]. Cryptosporidium hominis has been the cause of several large waterborne outbreaks. The largest took place in 1993 in Milwaukee, USA, where more than 400,000 people were infected [4]. Cryptosporidiosis is mainly transmitted by the fecal-oral route, usually through oocyst-contaminated water or food, or through contact with infected humans or ani- mals. As few as 10 ingested oocysts can cause infection [5]. Asymptomatic carriage occurs [6, 7] while symptomatic in- fection is associated with diarrhoea, abdominal pain, nau- sea, vomiting and fever that usually resolve within 2 weeks. Symptoms occur a few days up to 2 weeks after ingestion of oocysts [5]. Severe life-threating diarrhoea may develop among immunocompromised patients [8]. Gastrointestinal- and joint symptoms can persist for several months after the initial infection with Cryptosporidium [9]. The public health impact of the parasite was recognised in Sweden in 2004 * Correspondence: par.bjelkmar@folkhalsomyndigheten.se 1Department of Monitoring and Evaluation, Public Health Agency of Sweden, 171 83 Solna, Sweden Full list of author information is available at the end of the article The Author(s). 2017 Open Access This article is distributed under the terms of the Creative Commons Attribution 4.0 International License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.

BMC Public Health (2017) 17:328 DOI 10.1186/s12889-017-4233-8 when cryptosporidiosis became a notifiable disease and the parasite was also included in the World Health Organiza- tions Neglected Diseases Initiative in the same year [10]. In November and December 2010 a massive waterborne outbreak of C. hominis occurred in the city of stersund in Jmtland County, Sweden. Based on a retrospective cohort study, it was concluded that approximately 27,000 individ- uals were infected through the drinking water which made it the second biggest reported waterborne outbreak of cryptosporidiosis globally [11]. A couple of months later, in April 2011, drinking water from a municipal water treat- ment plant (WTP) in the neighboring county of Vsterbot- ten was suspected to be the source of a number of cases of cryptosporidiosis. A boil water notice (BWN) was therefore issued on 19 April and a web-based questionnaire was im- mediately created and published on the webpage of the mu- nicipality to collect epidemiological data. In order to complement the web-based questionnaire and better esti- mate the extent of the outbreak and to find its source, an additional study based on a postal questionnaire was per- formed in June 2011. The study was managed by the Vs- terbotten County Medical Office and the municipal environmental and health authorities in collaboration with the Public Health Agency of Sweden (at the time named Swedish Institute for Communicable Disease Control). Syndromic surveillance is defined as the real-time (or near real-time) collection, analysis, interpretation and dis- semination of health-related data [12]. As part of the on- going effort of development and evaluation of a syndromic surveillance system at the Public Health Agency, a retro- spective analysis of phone calls to a national health advice line from inhabitants living in Skellefte municipality dur- ing the time period of the outbreak was performed. No contemporaneous analysis of the phone calls was per- formed at the time of the outbreak. A new approach for early detection and improved situational awareness of local waterborne outbreaks was used where call patterns from individuals living in different drinking-water distribution areas were compared. The utility of syndromic surveillance systems for detecting and tracking local gastrointestinal outbreaks (GI) has been questioned [13] but systems based on data from health advice lines have been shown to be successful in a few cases [14, 15]. Globally, there are several examples of similar syndromic surveillance systems based on health advice lines [1618]. This study describes the outbreak investigation by sum- marizing the results from web-based and postal question- naires, human and environmental sampling and the analysis of phone calls to the health advice line. It outlines the extent and duration of the outbreak, risk factors and clinical characteristics of the infected persons, and discusses the potential for detecting the outbreak earlier. Figure 1 de- picts a time line indicating for which time periods the dif- ferent data sources were used in the analyses. Methods Study setting Skellefte is situated in Vsterbotten County geographic- ally located next to Jmtland County where the stersund outbreak occurred. The distance between Skellefte and stersund is almost 500 km. Skellefte is a municipality with a population of approximately 72,000 inhabitants. Twenty-eight water treatment plants are operating within the municipality. Two of these deliver water to the city of Skellefte; Slind WTP and Abborrverket WTP, where the latter delivers water to the majority of the inhabitants. All water treatment plants in the municipality use ground- water as the water source except Abborrverket which uses surface water obtained from the river Skelleftelven. Abborrverket WTP produces approximately 18,000 m3 of treated water daily to 44,000 of the 72,000 inhabitants in the municipality (31 March 2011). The normal water in- take to Abborrverket is located far out and deep in the river but due to icing during the winter months the intake is shifted to a more shallow position closer to shore where the ice can be removed more easily. Microbiological investigation Human samples Fecal samples from patients seeking healthcare for gastro- intestinal illness were analysed with standard techniques for enteric bacterial pathogens; polymerase chain reaction (PCR) for analysis of noro- and sapoviruses and micros- copy for analysis of Entamoeba spp. and Giardia intesti- nalis. Samples were only sporadically analysed for presence of Cryptosporidium oocysts up until 19 April 2011, when the current outbreak was first suspected. An intensification of testing for Cryptosporidium followed from that time until 1 July 2011 when the outbreak was considered over. Samples tested for Cryptosporidium were analysed using standard concentration technique followed by modified Ziehl-Neelsen staining [19]. A subset of posi- tive Cryptosporidium samples (n = 26) were sent to the Swedish Institute for Communicable Disease Control for species identification by PCR restriction fragment length polymorphism (RFLP) analysis of the rRNA gene [20, 21]. Subtypes were characterized by sequence analysis of the 60 kDa glycoprotein (gp60) gene [22, 23]. Environmental samples At the time of the outbreak Abborrverket WTP used floc- culation and sedimentation followed by sand filtering and chlorination for water treatment. This water treatment setup could be sufficient for removal of Cryptosporidium oocysts if the processes work optimally and the concentra- tion of oocysts is relatively low, but ultraviolet (UV) treat- ment is generally preferred as a disinfectant [24]. The winter intake was used from 19 November 2010 until 19 April 2011. A total of 38 samples were collected from the Bjelkmar et al. BMC Public Health (2017) 17:328 Page 2 of 10 drinking water system during a period of 5 months, 19 April to 15 September 2011. These samples included raw water from the river Skelleftelven, i.e. incoming water to Abborrverket WTP, treated water at Abborrverket WTP and samples taken from the distribution net. Twelve influent and twelve effluent wastewater samples were collected at the main sewage water treatment plant (SWTP) Tuvan. Moreover, in order to investigate possible causes of contamination of Skelleftelven and to trace sources of oocysts, 9 samples were collected from the wastewater and storm water systems and from other rele- vant locations. Water samples were analysed for Cryptosporidium oo- cysts according to ISO 15553:2006 [25] with filtration of water (101000 L), immunomagnetic separation (IMS) and immunofluorescence (IFL) microscopy. The slides with concentrated and purified material were identified by fluorescent-marked oocysts specific in size, shape, internal structure and DAPI-(4,6-diamidino-2-phenylindole)- stained nuclei. Wastewater samples were analyzed as water samples but without passing filters and in smaller volumes, 50100 mL for influent wastewater and 0.30.5 L for efflu- ent wastewater. Two sediment samples from the inside of the influent raw water pipe were also analysed as water sample but without filtration before IMS. DNA from one wastewater concentrate was analysed by sequence analysis of the gp60 gene as described for human samples [22, 23]. Epidemiological investigation Web-based questionnaire The same day as the BWN was issued, on 19 April 2011, a web-based questionnaire (Additional file 1) was created in order to immediately start collecting epidemiological data. The value of such a questionnaire was demonstrated in the preceding cryptosporidiosis outbreak in stersund [11] and those experiences were applied here as well. The questionnaire was made available to the public on the website of the municipality on the evening the same day, and was closed on 9 May 2011. The public was informed of the questionnaire by press releases and there were also links to it from key web pages such as the local newspaper and Vsterbotten County Council. The full data set was summarised after the outbreak was considered to be over. Visitors to the webpage who were residents of Skellefte municipality, both individuals with and without GI symp- toms, were asked to answer a set of questions regarding gastrointestinal illness in the family. A case attributed to the outbreak was defined as a person with residential ad- dress within Skellefte municipality with 3 loose stools per day for at least 1 day with onset between 1 April and 5 May 2011. Respondents with a date of symptom onset be- fore 1 April or after 5 May, persons who had travelled abroad 2 weeks prior to symptom onset, as well as individ- uals with a residential postal code outside Vsterbotten County were excluded from the analysis. Remaining re- spondents who did not fulfil the criteria of having 3 loose stools per day were considered non-cases. More detailed analyses of the data were not performed since the follow- up postal survey was conducted. Postal questionnaire A retrospective cohort study was performed in June 2011 by sending a questionnaire to a random sample of 1754 citizens in the municipality of Skellefte (Additional file 2, Additional file 3). The random sample was stratified by age (05 years, 615 years, 1665 years and 66 years or older) and gender. Questions were asked to find out about the start and magnitude of the outbreak, the source of the outbreak and risk factors for disease. The questionnaire contained questions on demographics, onset, duration and occurrence of symptoms indicating cryptosporidiosis, and water consumption as well as history of symptoms be- fore 1 January 2011. Caretakers were asked to answer for children <15 years of age. A case attributed to the out- break was defined as a person with 3 loose stools per day for at least 1 day with onset between 1 December 2010 and 31 May 2011. Statistical analysis of the postal questionnaire Each of the 1754 respondents were assigned a random number and a barcode on the questionnaire was used to identify each respondent. The postal codes were matched to the water distribution areas of the WTPs. In a stratified survey study, weights are used to calculate the number of individuals in the population represented by each individ- ual in the sample. Binary logistic regression was used to Fig. 1 Time line indicating for which time periods the different data sources were used in the analyses Bjelkmar et al. BMC Public Health (2017) 17:328 Page 3 of 10 find associated variables for the propensity of responding to the survey. Age, gender and water supply were used to calibrate the weights for non-response to adjust for unbal- ance between the sample and the population. The association between the binary outcome of case/ non-case and the exposure variables was analysed by binary logistic regression. Included in the model as covariates and exposure variables were gender, age (05 years, 615 years, 1665 years, and 66 years or older), gastric ulcer (yes, no), irritable bowel syndrome (yes, no), Crohns disease (yes, no), celiac disease (yes, no), lactose intolerance (yes, no), immunodeficiency disease (yes, no), average tap water con- sumption (<1 glass, 1 glass, 25 glasses, >5 glasses) and household water supply (Abborrverket, not Abborrverket or not from any WTP/own well). The results from the binary logistic regression were expressed as odds ratios (OR). All I do not know an- swers for binary questions were regarded as non- informative and were set as missing values prior to the analysis. Missing values for binary variables were then given a value (yes, no) using multiple imputation chain equations [26]. The chains contained all exposure vari- ables plus the outcome non-case/case [27]. Twenty data- sets with different imputed values for missing data were created and binary logistic regression results from each dataset were weighted together into one result using Rubins formula [28]. All analyses were performed in the statistical software R (version 3.3.2) using the packages survey (version 3.31.2), MICE (version 2.25) and the gen- eralized linear model function (glm) in the base R package stats. In all analyses a p-value less than 0.05 was used as a significant result and in case of estimated confidence in- tervals a confidence level of 95% was applied. Analysis of phone calls to a health advice line Healthcare Guide 1177 is a national Swedish telephone health advice line staffed by nurses. The service provides advice and information about urgent, but non-life- threatening, health problems. The medical record cre- ated for each consultation includes a structured data field, called the contact cause, that represents the most severe symptom as assessed by the nurse [29]. There are almost 200 contact causes in the services medical deci- sion support system but only a handful are related to GI problems. For the purpose of this study daily call counts on GI symptoms were retrospectively extracted from the service for inhabitants in Skellefte municipality from 1 August 2010 to 18 April 2011. The contact causes vomiting or nausea, diarrhoea and stomach pain were used since changes in contact patterns for these symptoms previously have been shown in outbreaks of cryptosporidiosis [14]. In addition, for each call, infor- mation on the postal code of the registered residence ad- dress of the patient was extracted. Postal codes were divided into two geographical regions; belonging to the distribution area of Abborrverket WPT or not, and the number of inhabitants in the corresponding regions were calculated. To compare the call patterns of GI-related symptoms between these two regions a previ- ously published outbreak detection algorithm [14] was used but with a minor modification. No analyses were performed for the period from the BWN and onwards since, as the in- formation of an ongoing outbreak becomes public, the con- tact pattern to the health advice line changes drastically and it is challenging to adjust for this in the analyses. The daily call count, Ct , i, for one contact cause or a sin- gle group of contact causes at day t for geographical re- gion i was classified as an outbreak signal if it exceeded a threshold Tt , i: Tt;i max L; V ; V Et;i L SDt;i; L 3; 5 f g Et;i pt;i Ni; SDt;i Ni pt;i q 1pt;i; pt;i Pni j1;ji P C;j 10 Pni j1;jiNj ; t7; t8; t9; t10; t11; t12; t13; t14 f g; 2; if t7; t14 f g 1; if t8; t9; t10; t11; t12; t13 f g where L is the threshold level for a weak and strong outbreak signal respectively, V is the threshold for a positive outbreak signal, Et , i is the expected number of calls and SDt , i is the standard deviation, both based on a binomial distribution, Niis the population size of geographical region i, pt , i is the probability of a single call per inhabitant per day, and ni is the number of geographical regions in the analysis. In the current study, two geographical regions were in- cluded: Abborrverket distribution area and not Abborrverket distribution area. It is important to note that calls from inhabitants of the geographical region under investigation are not included in the calculation of its threshold since that would increase the thresh- old if an outbreak in that region has been ongoing for more than 6 days. Compared to the previously published algorithm, the time period for the calcula- tion of pt , i has been modified. Here, calls for 8 days, t-7 to t-14, were included. Since the call patterns dif- fer between different weekdays, call counts for the weekdays matching the day for which the threshold is calculated, t-7 and t-14, has a weight of 2. The Bjelkmar et al. BMC Public Health (2017) 17:328 Page 4 of 10 motivation for this modification of the algorithm was primarily to reduce the risk of calculating pt , i based on small number of calls. Results Microbiological investigation Human samples Between 1 January and 1 July 2011, 145 laboratory con- firmed cases of domestic cryptosporidiosis were reported from Vsterbotten County. Only a handful were reported before 19 April, including one case on 15 April and two on 18 April. Genotyping identified C. hominis subtype IbA10G2 in samples from 24 confirmed cases, while no amplification product was obtained from the remaining two samples that were tested. No other gastrointestinal pathogens were found in a subset of the samples that were positive for Cryptosporidium. Environmental samples Cryptosporidium oocysts could not be detected in any of the 38 samples collected from the drinking water system. In influent and effluent wastewater samples from Tuvan SWTP oocysts were detected in 10 out of 24 samples. The concentration of oocysts in influent wastewater was highest on 22 April 2011 at 150,000 oocysts/L and de- clined to 6200 oocysts/L on 1 June 2011. From 27 June 2011 no oocysts were detected in influent wastewater. In effluent wastewater the concentration was highest on 8 June 2011 with a concentration of 12,000 oocysts/L. In subsequent samples the concentration varied between 1700 and 4200 oocysts/L and from 27 June 2011 the concentration was below the detection limit. Molecular investigation of one wastewater sample revealed C. hominis subtype IbA10G2. In the remaining 9 water and sediment samples collected at other places no oocysts were detected. Epidemiological investigation Web-based questionnaire The epidemiological curve based on the web-based questionnaire (Fig. 2) showed that the number of cases declined after a couple of days following the BWN and verified the hypothesis of an ongoing waterborne out- break. Importantly, it also indicated that the outbreak started well before 1 April. In total 12,358 individuals answered the questionnaire and 11,065 remained after exclusions. The results from the questionnaire were con- tinually monitored in order to provide information for decision making based on the extent of the outbreak, who were being affected and to follow up the effect of interventions. Moreover, it was used to inform the in- habitants about the progress of the outbreak and these reports were highly appreciated. Postal questionnaire In total, 1099 out of 1754 (63%) questionnaires were an- swered and returned for analysis. The survey showed that 26.4% of the respondents fulfilled the case defin- ition, i.e. self-reported diarrhoea (3 loose stools per day) between 1 December 2010 and 31 May 2011, which corresponds to an estimate of 18,449 cases (Table 1). The data from the survey also provided evidence that the outbreak started in January and ended by the end of May (Fig. 3). April was the peak month with 6969 cases. If the outbreak had been detected earlier and we assume that all cases from 1 February forward had remained healthy, the estimation is that the outbreak would have affected 2273 individuals, corresponding to approxi- mately 12% the current outbreak size. Only the variables age and water supply were identi- fied as risk factors for infection (Table 2). Divided into age groups, children up to 5 years were most affected, 37.2%, while the group of 66 years and above were least affected, 12.1% (Table 3). Among the different water supplies in Skellefte, water from Abborrverket WPT was the only supply that significantly correlated with an increased risk of infection (p < 0.001). Approximately 1 in 3 (32.7%) living in the distribution area of Abborrver- ket WPT had symptoms of cryptosporidiosis, compared to 16.2% of inhabitants living in other areas (Table 4). The most common symptoms, each present in more than 70% of the respondents that fulfilled the case defin- ition, were fatigue, abdominal pain, upset stomach, and watery diarrhoea (Table 5). Health advice line Starting on 30 December 2010, the retrospective analysis showed a sequence of 6 days of consecutive outbreak sig- nals regarding GI symptoms from individuals living in the distribution area of Abborrverket WTP (Fig. 4). Four of those were strong. A large number of outbreak signals for inhabitants living in the distribution area of Abborrverket WTP were evident during the following time period up until the BWN. In contrast, very few outbreak signals regarding GI symptoms were present for Abborrverket WPT distribu- tion area during the autumn and early winter of 2010. However, there was a small cluster of five outbreak signals between 20 November and 29 November 2010, but they were weak and not on consecutive days, hence the inter- pretation was that those outbreak signals were inconclu- sive. For the other geographical area in the analysis, individuals not living in the distribution area of Abborr- verket WTP, only one weak outbreak signal was present during the entire time-period under investigation - em- phasizing the abnormality of the identified outbreak signal pattern for the distribution area of Abborrverket WTP in the beginning of 2011. Similar results are obtained using Bjelkmar et al. BMC Public Health (2017) 17:328 Page 5 of 10 the original definition of the outbreak algorithm and with other groupings of ages and contact causes related to cryptosporidiosis (results not shown). When comparing the current outbreak signals based on geographical regions corresponding to the distribution of drinking water with outbreak signals based on (adult) GI calls from the entire Skellefte municipality with respect to the other municipalities within Vsterbotten County [14], the two patterns are similar and suggest the same time for outbreak detection: beginning of January 2011. Discussion The three cases of cryptosporidiosis in the middle of April together with other indications from informal sources re- garding large numbers of sick people, and higher-than- normal contacts regarding symptoms of gastrointestinal illness reported by the nurses staffing the regional health advice line, led the authorities to suspect an outbreak. However, our epidemiological investigation shows that the outbreak had already started, unnoticed to the authorities, in the beginning of January 2011. High norovirus activity together with only a handful of domestic cases of crypto- sporidiosis reported in Vsterbotten County between January and 19 April 2011 were contributing factors to the late detection of the outbreak. New routines are now in place in Vsterbotten County where analysis of Crypto- sporidium is performed on fecal samples if there are clus- ters of cases with gastrointestinal symptoms or other indications of an outbreak. If the outbreak had been detected in the beginning of the year by systematic monitoring of the telephone calls as described in this study, it is very likely that the outbreak would have ended during January. Two facts support this conclusion. First, once the outbreak was suspected the BWN was an effective intervention that substantially lim- ited illness within a few days. A similar delay in the Fig. 2 Epidemiological curve based on observed cases in the web questionnaire Table 1 Population estimates of cases and non-cases of Cryptosporidium-infection in Skellefte between December 2010 and May 2011 Status N SE (N) 95% CI (N) N (%) Non-cases 51,618 1214 49,239 53,997 73.7 Cases 18,448 1191 16,114 20,782 26.3 N Number, SE standard error, CI confidence interval Based on postal questionnaire Fig. 3 Epidemiological curve of population estimates of number of cases from the postal questionnaire Bjelkmar et al. BMC Public Health (2017) 17:328 Page 6 of 10 decrease of reported cases was seen in the stersund out- break [11] and it is explained by the time it takes to de- velop symptoms after ingestion of oocyst. Second, the outbreak signals from the described analyses of telephone calls would have given a strong indication during January that the outbreak was waterborne and which drinking water supply to suspect (Abborrverket WTP). We therefor argue that such an early outbreak detection followed by a timelier BWN in January 2011 would have limited the out- break substantially from approximately 18,500 cases down to 2300 cases if all who fell ill after 31 January had remained healthy. The potential of syndromic surveillance systems based on analysing telephone call patterns to Healthcare Guide 1177 for early event detection and situational awareness of local outbreaks has been shown previously [14]. In the current work the concept was taken a step further by comparing call patterns between water distribution areas that were based on groups of postal codes. The im- portance of this should not be underestimated. In the situation of an unknown waterborne outbreak, or other types of local outbreaks where the spread matches geographical areas used in the analysis, this procedure gives a more timely indication of the underlying cause and therefore substantially increases the chances of ef- fective countermeasures. Since water distribution areas are known, the approach can be used in systems for syn- dromic surveillance. There is always a tradeoff between sensitivity and spe- cificity in signal detection. In practical terms it is the in- stitution that is eligible to act on the signal that needs to find a reasonable protocol for signal evaluation and val- idation. To increase the sensitivity and hence the poten- tial of timely detection of local outbreaks, which usually are very short-lived in contrast to the outbreak under in- vestigation here, the outbreak algorithm used operates on a daily basis. This has the drawback of reduced speci- ficity, i.e. that more false positive outbreak signals are generated due to randomness, especially for geographical regions where the population size is small. Despite this, and even though the daily call counts are relatively low, the outbreak signal pattern shown in Fig. 4 is excep- tional and clearly indicates that individuals living in the distribution area of Abborrverket WTP report more GI symptoms compared to individuals living in other areas. Moreover, this outbreak signal pattern is similar if other groupings of age and contact causes related to symptoms of cryptosporidiosis are used. Although possible sources of contamination were in- vestigated and discussed no conclusive information could be found. Several samples from the drinking water system and the environment were analysed for Crypto- sporidium oocysts but none were detected - apart from the findings in wastewater samples. The most likely the- ory in our opinion is that the winter intake of water to Abborrverket WTP, which is more exposed to contamin- ation since it is located more shallowly in the river and closer to shore compared to the summer intake, was contaminated with Cryptosporidium oocysts from sew- age from one or several sources. However, data on weekly maximal turbidity and bacteriological counts (Escherichia coli, general coliform bacteria, enterococci and Clostridium perfringens) in raw water to Abborrver- ket WTP for the period October 2010 to March 2011 had been within normal levels so such a contamination, if present, was not detected in the routine testing at the WTP. The water intake was shifted to the summer position on the same day as the BWN was issued on 19 April 2011, which may explain why no Cryptosporidium oo- cysts were found in the water samples, since they were all taken after 19 April. It is worth noting that the out- break signals from the syndromic surveillance algorithm present in November 2010 coincide with the shift to the winter intake which might indicate a contamination at that point in time as well - although probably unrelated Table 2 Significant risk factors for infection based on postal questionnaire Odds ratio 95% CI P-value* Age 0-5 4.22 2.66 6.68 <0.001 6-15 2.28 1.42 3.68 0.001 16-65 3.08 1.96 4.83 <0.001 66- 1.00 Water source Not from any WTP/own well 1.00 Abborrverket WTP 2.30 1.49 3.56 <0.001 Not Abborrverket WTP 1.14 0.68 1.91 0.613 CI confidence interval, WTP water treatment plant *Fishers exact P - value Table 3 Population estimates of cases and non-cases of Cryptosporidium-infection in Skellefte between December 2010 and May 2011 divided into age groups Status Age N SE (N) 95% CI (N) N (%) Non-cases 0-5 2433 121 2195 2671 62.8 6-15 5542 208 5135 5950 75.3 16-65 30,728 1148 28,479 32,977 69.6 66- 12,914 326 12,276 13,553 87.9 Cases 0-5 1442 120 1207 1676 37.2 6-15 1819 202 1423 2215 24.7 16-65 13,402 1132 11,183 15,621 30.4 66- 1786 301 1196 2377 12.1 N number, SE standard error; CI confidence interval Based on postal questionnaire Bjelkmar et al. BMC Public Health (2017) 17:328 Page 7 of 10 to the current outbreak. The fact that Cryptosporidium oocysts were found in wastewater is in our opinion re- lated to the fact that a substantial part of the population connected to the municipal SWTP Tuvan was infected with C. hominis IbA10G2. Thus, although the initial cause of the outbreak remains unknown, it was most certainly caused by fecal contamination of human origin since C. hominis is almost exclusively human specific. Compared to the stersund outbreak [11] only age was the common risk factor. In contrast, the current study did not find statistical significance for any of the underlying diseases nor amount of water consumed. Symptom pro- files were almost identical between the outbreaks. The same Cryptosporidium gp60 subtype was found respon- sible for both the current and the stersund outbreak. It is in our opinion likely that the outbreaks were related since this subtype seldom is found in domestic cases in Sweden, in contrast to other European countries, and the time period between the outbreaks was short. However, similarity on gp60 is not conclusive evidence [30] and the question of whether two outbreaks were related is currently investigated by whole genome sequencing. Speculatively, one or a few infected individuals from the stersund outbreak brought the parasite to Skellefte and caused a second outbreak through spread of Cryptosporid- ium oocysts via sewage, into the river, finally ending up in the drinking water since the microbial barriers present in Abborrverket WPT at the time were insufficient to inacti- vate or remove the oocysts. After the outbreak was identified, the water distribution system was flushed to remove the contamination and work to improve the water treatment in Abborrverket WTP was started. Since the large outbreak in stersund only took place a few months earlier the municipality of Skellefte could utilize experience from the actions taken to stop the former outbreak. Even so, the BWN had to be kept in place for 5 months, compared to 3 months in stersund. This was partly due to the longer period of time it took to install an ultraviolet unit as an additional Table 4 Population estimates of cases and non-cases of Cryptosporidium-infection in Skellefte between December 2010 and May 2011 divided into water supply categories Status Category N SE (N) 95% CI (N) N (%) Non-cases Not Abborrverket WTP 22,649 642 21,392 23,906 83.8 Abborrverket WTP 28,696 1033 26,944 30,994 67.3 Cases Not Abborrverket WTP 4368 624 3145 5590 16.2 Abborrverket WTP 14,081 1019 12,084 16,078 32.7 N number, SE standard error, CI confidence interval Based on postal questionnaire Table 5 Clinical features of Cryptosporidium-infection cases in the municipality of Skellefte during December 2010 to May 2011 Proportion with symptom (%) 95% CI (%) Fatigue 78.5 72.4 84.7 Abdominal pain 73.3 66.8 79.8 Upset stomach 71.4 64.7 78.2 Diarrhoea Watery 70.2 63.4 77.0 Bloody 0.9 0.0 2.5 Nausea 63.5 56.1 70.9 Headache 46.9 39.3 54.5 Vomiting 35.8 28.6 43.1 Fever >38 C 36.5 28.2 42.8 Joint pain 27.4 20.4 34.4 Pain in eyes 14.6 9.1 20.1 CI confidence interval Based on postal questionnaire Fig. 4 Daily call counts from Skellefte municipality to Healthcare Guide 1177 regarding GI symptoms from 1 August 2010 until the day before the BWN on 19 April 2011.

BMC Public Health (2017) 17:328 Page 8 of 10 microbiological barrier in Abborrverket WTP as well as a longer and more complex water distribution network that had to be flushed. As of November 2016, the municipality of Skellefte is in the process of rebuilding their infrastruc- ture for production of drinking water. This work had started before the outbreak of cryptosporidiosis. Conclusions Our investigation concludes that approximately 18,500 people in the municipality of Skellefte were infected by Cryptosporidium during the winter and spring of 2011 making it the second largest outbreak of cryptosporidiosis described in Europe to date. Cryptosporidium hominis subtype IbA10G2 was isolated from patient samples and wastewater. The epidemiological investigation strongly indicates that this outbreak was waterborne based on the vast number of cases, as well as the fact that the BWN were an effective countermeasure, and that people living in the water distribution area of one specific WTP were more likely to become ill. This conclusion is also strongly supported by the pattern of phone calls to the national health advice line Healthcare Guide 1177. We therefore firmly believe that the outbreak was waterborne and caused by C. hominis transmitted through the public water supplied by Abborrverket WTP even though no oocysts could be found in raw water or in drinking water. Moreover, our results show that the outbreak went unnoticed to the authorities for several months and that systematic monitoring of phone calls to the health advice line, as described in this study, could have limited the out- break to approximately 2300 cases compared to the current estimate of 18,500 cases. This new approach of linking health advice line calls to water distribution areas has been implemented in a system for syndromic surveillance deployed by the Public Health Agency of Sweden in 2016.

In a switching circuit, the idea is to simulate, as near as possible, the ideal switch having the properties of open circuit when off, short circuit when on, and an instantaneous transition between the two states. Parameters are chosen such that the "off" output is limited to leakage currents too small to affect connected circuitry; the resistance of the transistor in the "on" state is too small to affect circuitry; and the transition between the two states is fast enough not to have a detrimental effect.

The terms 'federalism' and 'confederalism' both have a root in the Latin word foedus, meaning treaty, pact or covenant. Their common meaning until the late eighteenth century was a simple league or inter-governmental relationship among sovereign states based upon a treaty. They were therefore initially synonyms. It was in this sense that James Madison in Federalist 39 had referred to the new United States as 'neither a national nor a federal Constitution, but a composition of both' (ie. neither a single large unitary state nor a league/confederation among several small states, but a hybrid of the two). In the course of the nineteenth century the meaning of federalism would come to shift, strengthening to refer uniquely to the novel compound political form, while the meaning of confederalism would remain at a league of states. Thus, this article relates to the modern usage of the word 'federalism'.

The required beliefs of these clauses include belief in a Supreme Being and belief in a future state of rewards and punishments. (Tennessee Constitution Article IX, Section 2 is one such example.) Some of these same states specify that the oath of office include the words "so help me God." In some cases these beliefs (or oaths) were historically required of jurors and witnesses in court. At one time, such restrictions were allowed under the doctrine of states' rights; today they are deemed to be in violation of the federal First Amendment, as applied to the states via the 14th amendment, and hence unconstitutional and unenforceable.

The ability to store and execute lists of instructions called programs makes computers extremely versatile, distinguishing them from calculators. The Church–Turing thesis is a mathematical statement of this versatility: any computer with a minimum capability (being Turing-complete) is, in principle, capable of performing the same tasks that any other computer can perform. Therefore, any type of computer (netbook, supercomputer, cellular automaton, etc.) is able to perform the same computational tasks, given enough time and storage capacity.

For at least a century before the establishment of the Augustan principate, Jews and Judaism were tolerated in Rome by diplomatic treaty with Judaea's Hellenised elite. Diaspora Jews had much in common with the overwhelmingly Hellenic or Hellenised communities that surrounded them. Early Italian synagogues have left few traces; but one was dedicated in Ostia around the mid-1st century BC and several more are attested during the Imperial period. Judaea's enrollment as a client kingdom in 63 BC increased the Jewish diaspora; in Rome, this led to closer official scrutiny of their religion. Their synagogues were recognised as legitimate collegia by Julius Caesar. By the Augustan era, the city of Rome was home to several thousand Jews. In some periods under Roman rule, Jews were legally exempt from official sacrifice, under certain conditions. Judaism was a superstitio to Cicero, but the Church Father Tertullian described it as religio licita (an officially permitted religion) in contrast to Christianity.

The characters encoded are numbers 0 to 9, lowercase letters a to z, uppercase letters A to Z, basic punctuation symbols, control codes that originated with Teletype machines, and a space. For example, lowercase j would become binary 1101010 and decimal 106.

Most of the Low Countries had come under the rule of the House of Burgundy and subsequently the House of Habsburg. In 1549 Holy Roman Emperor Charles V issued the Pragmatic Sanction, which further unified the Seventeen Provinces under his rule. Charles was succeeded by his son, King Philip II of Spain. In 1568 the Netherlands, led by William I of Orange, revolted against Philip II because of high taxes, persecution of Protestants by the government, and Philip's efforts to modernize and centralize the devolved-medieval government structures of the provinces. This was the start of the Eighty Years' War.

In a new and effective tactic, the Popular Front launched a rail blockade of Armenia, which caused petrol and food shortages because 85 percent of Armenia's freight came from Azerbaijan. Under pressure from the Popular Front the Communist authorities in Azerbaijan started making concessions. On September 25, they passed a sovereignty law that gave precedence to Azerbaijani law, and on October 4, the Popular Front was permitted to register as a legal organization as long as it lifted the blockade. Transport communications between Azerbaijan and Armenia never fully recovered. Tensions continued to escalate and on December 29, Popular Front activists seized local party offices in Jalilabad, wounding dozens.

In 2012, New York City had the lowest overall crime rate and the second lowest murder rate among the largest U.S. cities, having become significantly safer after a spike in crime in the 1970s through 1990s. Violent crime in New York City decreased more than 75% from 1993 to 2005, and continued decreasing during periods when the nation as a whole saw increases. By 2002, New York City's crime rate was similar to that of Provo, Utah, and was ranked 197th in crime among the 216 U.S. cities with populations greater than 100,000. In 2005 the homicide rate was at its lowest level since 1966, and in 2007 the city recorded fewer than 500 homicides for the first time ever since crime statistics were first published in 1963. In the first six months of 2010, 95.1% of all murder victims and 95.9% of all shooting victims in New York City were black or Hispanic; additionally, 90.2 percent of those arrested for murder and 96.7 percent of those arrested for shooting someone were black or Hispanic. New York experienced a record low of 328 homicides in 2014 and has a far lower murder rate than other major American cities.

Possible improvements include clarification of clinical trial regulations by FDA. Furthermore, appropriate economic incentives could persuade pharmaceutical companies to invest in this endeavor. Antibiotic Development to Advance Patient Treatment (ADAPT) Act aims to fast track the drug development to combat the growing threat of 'superbugs'. Under this Act, FDA can approve antibiotics and antifungals treating life-threatening infections based on smaller clinical trials. The CDC will monitor the use of antibiotics and the emerging resistance, and publish the data. The FDA antibiotics labeling process, 'Susceptibility Test Interpretive Criteria for Microbial Organisms' or 'breakpoints', will provide accurate data to healthcare professionals. According to Allan Coukell, senior director for health programs at The Pew Charitable Trusts, "By allowing drug developers to rely on smaller datasets, and clarifying FDA's authority to tolerate a higher level of uncertainty for these drugs when making a risk/benefit calculation, ADAPT would make the clinical trials more feasible."

During the initial punk era, a variety of entrepreneurs interested in local punk-influenced music scenes began founding independent record labels, including Rough Trade (founded by record shop owner Geoff Travis) and Factory (founded by Manchester-based television personality Tony Wilson). By 1977, groups began pointedly pursuing methods of releasing music independently , an idea disseminated in particular by the Buzzcocks' release of their Spiral Scratch EP on their own label as well as the self-released 1977 singles of Desperate Bicycles. These DIY imperatives would help form the production and distribution infrastructure of post-punk and the indie music scene that later blossomed in the mid-1980s.

Promote and Publicize the Party's Agenda. An important aim of the minority leader is to develop an electorally attractive agenda of ideas and proposals that unites his or her own House members and that energizes and appeals to core electoral supporters as well as independents and swing voters. Despite the minority leader's restricted ability to set the House's agenda, there are still opportunities for him to raise minority priorities. For example, the minority leader may employ, or threaten to use, discharge petitions to try and bring minority priorities to the floor. If he or she is able to attract the required 218 signatures on a discharge petition by attracting majority party supporters, he or she can force minority initiatives to the floor over the opposition of the majority leadership. As a GOP minority leader once said, the challenges he confronted are to "keep our people together, and to look for votes on the other side."

St. John's served as the capital city of the Colony of Newfoundland and the Dominion of Newfoundland before Newfoundland became Canada's tenth province in 1949. The city now serves as the capital of Newfoundland and Labrador, therefore the provincial legislature is located in the city. The Confederation Building, located on Confederation Hill, is home to the House of Assembly along with the offices for the Members of the House of Assembly (MHAs) and Ministers. The city is represented by ten MHAs, four who are members of the governing Progressive Conservative Party, three that belong to the New Democratic Party (NDP), and three that belong to the Liberal Party. Lorraine Michael, leader of the NDP since 2006, represents the district of Signal Hill-Quidi Vidi.

Rossiyskaya Sovetskaya Federativnaya Sotsialisticheskaya Respublika listen (help·info)) commonly referred to as Soviet Russia or simply as Russia, was a sovereign state in 1917–22, the largest, most populous, and most economically developed republic of the Soviet Union in 1922–91 and a sovereign part of the Soviet Union with its own legislation in 1990–91. The Republic comprised sixteen autonomous republics, five autonomous oblasts, ten autonomous okrugs, six krais, and forty oblasts. Russians formed the largest ethnic group. To the west it bordered Finland, Norway and Poland; and to the south, China, Mongolia and North Korea whilst bordering the Arctic Ocean to the north, the Pacific Ocean to the east and the Black sea and Caspian Sea to the south. Within the USSR, it bordered the Baltic republics (Lithuania, Latvia and Estonia), the Byelorussian SSR and the Ukrainian SSR to the west.

Evolutionary ideas, although not natural selection, were accepted by German biologists accustomed to ideas of homology in morphology from Goethe's Metamorphosis of Plants and from their long tradition of comparative anatomy. Bronn's alterations in his German translation added to the misgivings of conservatives, but enthused political radicals. Ernst Haeckel was particularly ardent, aiming to synthesise Darwin's ideas with those of Lamarck and Goethe while still reflecting the spirit of Naturphilosophie. Their ambitious programme to reconstruct the evolutionary history of life was joined by Huxley and supported by discoveries in palaeontology. Haeckel used embryology extensively in his recapitulation theory, which embodied a progressive, almost linear model of evolution. Darwin was cautious about such histories, and had already noted that von Baer's laws of embryology supported his idea of complex branching.

Some Western writers claim that the immaculate conception of Mary is a teaching of Islam. Thus, commenting in 1734 on the passage in the Qur'an, "I have called her Mary; and I commend her to thy protection, and also her issue, against Satan driven away with stones", George Sale stated: "It is not improbable that the pretended immaculate conception of the virgin Mary is intimated in this passage. For according to a tradition of Mohammed, every person that comes into the world, is touched at his birth by the devil, and therefore cries out, Mary and her son only excepted; between whom, and the evil spirit God placed a veil, so that his touch did not reach them. And for this reason they say, neither of them were guilty of any sin, like the rest of the children of Adam."

Most wrestling matches last for a set number of falls, with the first side to achieve the majority number of pinfalls, submissions, or countouts being the winner. Historically, matches were wrestled to 3 falls ("best 2 out of 3") or 5 falls ("best 3 out of 5"). The standard for modern matches is one fall. However, even though it is now standard, many announcers will explicitly state this (e.g. "The following contest is set for one fall with a 20-minute time limit"). These matches are given a time limit; if not enough falls are scored by the end of the time limit, the match is declared a draw. Modern matches are generally given a 10- to 30-minute time limit for standard matches; title matches can go for up to one hour. British wrestling matches held under Admiral-Lord Mountevans rules are 2 out of 3 falls.

By 1939, in his Prolegomena for the Oxford Shakespeare, McKerrow had changed his mind about this approach, as he feared that a later edition – even if it contained authorial corrections – would "deviate more widely than the earliest print from the author's original manuscript." He therefore concluded that the correct procedure would be "produced by using the earliest "good" print as copy-text and inserting into it, from the first edition which contains them, such corrections as appear to us to be derived from the author." But, fearing the arbitrary exercise of editorial judgment, McKerrow stated that, having concluded that a later edition had substantive revisions attributable to the author, "we must accept all the alterations of that edition, saving any which seem obvious blunders or misprints."

The fourth Digimon series, which began airing on April 7, 2002, radically departs from the previous three by focusing on a new and very different kind of evolution, Spirit Evolution, in which the human characters use their D-Tectors (this series' Digivice) to transform themselves into special Digimon called Legendary Warriors, detracting from the customary formula of having digital partners. After receiving unusual phone messages from Ophanimon (one of the three ruling Digimon alongside Seraphimon and Cherubimon) Takuya Kanbara, Koji Minamoto, Junpei Shibayama, Zoe Orimoto, Tommy Himi, and Koichi Kimura go to a subway station and take a train to the Digital World. Summoned by Ophanimon, the Digidestined realize that they must find the ten legendary spirits and stop the forces of Cherubimon from physically destroying the Digital World. After finding the ten spirits of the Legendary Warriors and defeating Mercurymon, Grumblemon, Ranamon, and Arbormon, they finally end up fighting Cherubimon hoping to foil his effort to dominate the Digital World. After the defeat of Cherubimon, the Digidestined find they must face an even greater challenge as they try to stop the Royal Knights—Dynasmon and Crusadermon—from destroying the Digital World and using the collected data to revive the original ruler of the Digital World: the tyrannical Lucemon. Ultimately the Digidestined fail in preventing Lucemon from reawakening but they do manage to prevent him from escaping into the Real World. In the final battle, all of the legendary spirits the digidestined have collected thus far merge and create Susanoomon. With this new form, the digidestined are able to effectively defeat Lucemon and save the Digital World. In general, Frontier has a much lighter tone than that of Tamers, yet remains darker than Adventure and Adventure 02.

The outcome of the First World War was disastrous for both the German Reich and the Russian Soviet Federative Socialist Republic. During the war, the Bolsheviks struggled for survival, and Vladimir Lenin recognised the independence of Finland, Estonia, Latvia, Lithuania and Poland. Moreover, facing a German military advance, Lenin and Trotsky were forced to enter into the Treaty of Brest-Litovsk, which ceded massive western Russian territories to the German Empire. After Germany's collapse, a multinational Allied-led army intervened in the Russian Civil War (1917–22).

Occasionally he played, or accompanied the singing of Delfina Potocka, for his friends. During the summer of 1849, his friends found him an apartment in Chaillot, out of the centre of the city, for which the rent was secretly subsidised by an admirer, Princess Obreskoff. Here in June 1849 he was visited by Jenny Lind.

The Reed Dance today is not an ancient ceremony but a development of the old "umchwasho" custom. In "umchwasho", all young girls were placed in a female age-regiment. If any girl became pregnant outside of marriage, her family paid a fine of one cow to the local chief. After a number of years, when the girls had reached a marriageable age, they would perform labour service for the Queen Mother, ending with dancing and feasting. The country was under the chastity rite of "umchwasho" until 19 August 2005.

The morning after the election, the major candidates were neck and neck. It was clear that the result in Ohio, along with two other states who had still not declared (New Mexico and Iowa), would decide the winner. Bush had established a lead of around 130,000 votes but the Democrats pointed to provisional ballots that had yet to be counted, initially reported to number as high as 200,000. Bush had preliminary leads of less than 5% of the vote in only four states, but if Iowa, Nevada and New Mexico had all eventually gone to Kerry, a win for Bush in Ohio would have created a 269–269 tie in the Electoral College. The result of an electoral tie would cause the election to be decided in the House of Representatives with each state casting one vote, regardless of population. Such a scenario would almost certainly have resulted in a victory for Bush, as Republicans controlled more House delegations. Therefore, the outcome of the election hinged solely on the result in Ohio, regardless of the final totals elsewhere. In the afternoon Ohio's Secretary of State, Ken Blackwell, announced that it was statistically impossible for the Democrats to make up enough valid votes in the provisional ballots to win. At the time provisional ballots were reported as numbering 140,000 (and later estimated to be only 135,000). Faced with this announcement, John Kerry conceded defeat. Had Kerry won Ohio, he would have won the election despite losing the national popular vote by over 3 million votes, a complete reversal of the 2000 election when Bush won the presidency despite losing the popular vote to Al Gore by over 500,000 votes.

The coronation of Charlemagne as emperor on Christmas Day 800 is regarded as a turning point in medieval history, marking a return of the Western Roman Empire, since the new emperor ruled over much of the area previously controlled by the western emperors. It also marks a change in Charlemagne's relationship with the Byzantine Empire, as the assumption of the imperial title by the Carolingians asserted their equivalence to the Byzantine state. There were several differences between the newly established Carolingian Empire and both the older Western Roman Empire and the concurrent Byzantine Empire. The Frankish lands were rural in character, with only a few small cities. Most of the people were peasants settled on small farms. Little trade existed and much of that was with the British Isles and Scandinavia, in contrast to the older Roman Empire with its trading networks centred on the Mediterranean. The empire was administered by an itinerant court that travelled with the emperor, as well as approximately 300 imperial officials called counts, who administered the counties the empire had been divided into. Clergy and local bishops served as officials, as well as the imperial officials called missi dominici, who served as roving inspectors and troubleshooters.

Heavy ice kept him from further exploration, and he returned to Spain in August. The first scientific map to show the North American East coast continuously, the 1527 world map known as the Padrón Real, was informed by Gomes' expedition, and labeled the Northeast as Tierra de Esteban Gómez in his honor.

In November 2013, Somalia received its first fiber optic connection. The country previously had to rely on expensive satellite links due to the civil conflict, which limited internet usage. However, residents now have access to broadband internet cable for the first time after an agreement reached between Hormuud Telecom and Liquid Telecom. The deal will see Liquid Telecom link Hormuud to its 17,000 km (10,500 mile) network of terrestrial cables, which will deliver faster internet capacity. The fiber optic connection will also make online access more affordable to the average user. This in turn is expected to further increase the number of internet users. Dalkom Somalia reached a similar agreement with the West Indian Ocean Cable Company (WIOCC) Ltd, which it holds shares in. Effective the first quarter of 2014, the deal will establish fiber optic connectivity to and from Somalia via the EASSy cable. The new services are expected to reduce the cost of international bandwidth and to better optimize performance, thereby further broadening internet access. Dalkom Somalia is concurrently constructing a 1,000 square mile state-of-the-art data center in Mogadishu.

Although he avoids the controversial topic of human origins in the rest of the book so as not to prejudice readers against his theory, here he ventures a cautious hint that psychology would be put on a new foundation and that "Light will be thrown on the origin of man".

The Heian period (平安時代, Heian jidai?) is the last division of classical Japanese history, running from 794 to 1185. The period is named after the capital city of Heian-kyō, or modern Kyōto. It is the period in Japanese history when Buddhism, Taoism and other Chinese influences were at their height. The Heian period is also considered the peak of the Japanese imperial court and noted for its art, especially poetry and literature. Although the Imperial House of Japan had power on the surface, the real power was in the hands of the Fujiwara clan, a powerful aristocratic family who had intermarried with the imperial family. Many emperors actually had mothers from the Fujiwara family. Heian (平安?) means "peace" in Japanese.

The humanists' close study of Latin literary texts soon enabled them to discern historical differences in the writing styles of different periods. By analogy with what they saw as decline of Latin, they applied the principle of ad fontes, or back to the sources, across broad areas of learning, seeking out manuscripts of Patristic literature as well as pagan authors. In 1439, while employed in Naples at the court of Alfonso V of Aragon (at the time engaged in a dispute with the Papal States) the humanist Lorenzo Valla used stylistic textual analysis, now called philology, to prove that the Donation of Constantine, which purported to confer temporal powers on the Pope of Rome, was an 8th-century forgery. For the next 70 years, however, neither Valla nor any of his contemporaries thought to apply the techniques of philology to other controversial manuscripts in this way. Instead, after the fall of the Byzantine Empire to the Turks in 1453, which brought a flood of Greek Orthodox refugees to Italy, humanist scholars increasingly turned to the study of Neoplatonism and Hermeticism, hoping to bridge the differences between the Greek and Roman Churches, and even between Christianity itself and the non-Christian world. The refugees brought with them Greek manuscripts, not only of Plato and Aristotle, but also of the Christian Gospels, previously unavailable in the Latin West.

In the U.S., a push for revisions of the FD&C Act emerged from Congressional hearings led by Senator Estes Kefauver of Tennessee in 1959. The hearings covered a wide range of policy issues, including advertising abuses, questionable efficacy of drugs, and the need for greater regulation of the industry. While momentum for new legislation temporarily flagged under extended debate, a new tragedy emerged that underscored the need for more comprehensive regulation and provided the driving force for the passage of new laws.

Article 10 of the Berne Convention mandates that national laws provide for limitations to copyright, so that copyright protection does not extend to certain kinds of uses that fall under what the treaty calls "fair practice," including but not limited to minimal quotations used in journalism and education. The laws implementing these limitations and exceptions for uses that would otherwise be infringing broadly fall into the categories of either fair use or fair dealing. In common law systems, these fair practice statutes typically enshrine principles underlying many earlier judicial precedents, and are considered essential to freedom of speech.

The unemployment rate reached its peak of 20% in 2005. Since then, it has decreased to 7% in 2013, which is only slightly above the national average. The decrease is caused on the one hand by the emergence of new jobs and on the other by a marked decrease in the working-age population, caused by emigration and low birth rates for decades. The wages in Thuringia are low compared to rich bordering Lands like Hesse and Bavaria. Therefore, many Thuringians are working in other German Lands and even in Austria and Switzerland as weekly commuters. Nevertheless, the demographic transition in Thuringia leads to a lack of workers in some sectors. External immigration into Thuringia has been encouraged by the government since about 2010 to counter this problem.

Local law enforcement is divided between County Sheriff's Offices and Municipal Police Departments. Tennessee's Constitution requires that each County have an elected Sheriff. In 94 of the 95 counties the Sheriff is the chief law enforcement officer in the county and has jurisdiction over the county as a whole. Each Sheriff's Office is responsible for warrant service, court security, jail operations and primary law enforcement in the unincorporated areas of a county as well as providing support to the municipal police departments. Incorporated municipalities are required to maintain a police department to provide police services within their corporate limits.

As of 2011, there have been six series — Digimon Adventure, the follow-up sequel Digimon Adventure 02, Digimon Tamers, Digimon Frontier, Digimon Data Squad and Digimon Fusion. The first two series take place in the same fictional universe, but the third, fourth, fifth and sixth each occupy their own unique world. Each series is commonly based on the original storyline but things are added to make them unique. However, in Tamers, the Adventure universe is referred to as a commercial enterprise — a trading card game in Japan, plus a show-within-a-show in the English dub. It also features an appearance by a character from the Adventure universe. In addition, each series has spawned assorted feature films. Digimon still shows popularity, as new card series, video games, and movies are still being produced and released: new card series include Eternal Courage, Hybrid Warriors, Generations, and Operation X; the video game, Digimon Rumble Arena 2; and the previously unreleased movies Revenge of Diaboromon, Runaway Locomon, Battle of Adventurers, and Island of Lost Digimon. In Japan, Digital Monster X-Evolution, the eighth TV movie, was released on January 3, 2005, and on December 23, 2005 at Jump Festa 2006, the fifth series, Digimon Savers was announced for Japan to begin airing after a three-year hiatus of the show. A sixth television series, Digimon Xros Wars, began airing in 2010, and was followed by a second season, which started on October 2, 2011 as a direct sequel to Digimon Xros Wars.

In 1762, George III acquired Buckingham House and it was enlarged over the next 75 years. During the 18th century, London was dogged by crime, and the Bow Street Runners were established in 1750 as a professional police force. In total, more than 200 offences were punishable by death, including petty theft. Most children born in the city died before reaching their third birthday. The coffeehouse became a popular place to debate ideas, with growing literacy and the development of the printing press making news widely available; and Fleet Street became the centre of the British press.

Some opponents further claim that affirmative action has undesirable side-effects and that it fails to achieve its goals. They argue that it hinders reconciliation, replaces old wrongs with new wrongs, undermines the achievements of minorities, and encourages groups to identify themselves as disadvantaged, even if they are not. It may increase racial tension and benefit the more privileged people within minority groups at the expense of the disenfranchised within better-off groups (such as lower-class whites and Asians).There has recently been a strong push among American states to ban racial or gender preferences in university admissions, in reaction to the controversial and unprecedented decision in Grutter v. Bollinger. In 2006, nearly 60% of Michigan voters decided to ban affirmative action in university admissions. Michigan joined California, Florida, Texas, and Washington in banning the use of race or sex in admissions considerations. Some opponents believe, among other things, that affirmative action devalues the accomplishments of people who belong to a group it's supposed to help, therefore making affirmative action counter-productive. Furthermore, opponents of affirmative action claim that these policies dehumanize individuals and applicants to jobs or school are judged as members of a group without consideration for the individual person.

In 1063, Ferdinand I of Castile divided his realm among his sons, and the Kingdom of Galicia was granted to Garcia II of Galicia. In 1072, it was forcibly annexed by Garcia's brother Alfonso VI of León; from that time Galicia was united with the Kingdom of León under the same monarchs. In the 13th century Alfonso X of Castile standardized the Castilian language and made it the language of court and government. Nevertheless, in his Kingdom of Galicia the Galician language was the only language spoken, and the most used in government and legal uses, as well as in literature.

Elizabeth I of England, primarily interested in trade with the east, collaborated with English merchants to form the first trading companies to the far-flung regions, using their own jargon. Their goals were to obtain trading concessions by treaty. The queen chartered the Company of Merchants of the Levant, shortened to Levant Company, and soon known also as The Turkey Company, in 1581. In 1582, the ship The Great Susan transported the first ambassador, William Harebone, to the Ottoman Porte (government of the Ottoman Empire) at Constantinople. Compared to Anatolia, Levant also means "land of the rising sun," but where Anatolia always only meant the projection of land currently occupied by the Republic of Turkey, Levant meant anywhere in the domain ruled by the Ottoman Porte. The East India Company (short for a much longer formal name) was chartered in 1600 for trade to the East Indies.

For instance, to keep their party colleagues "on message," they insure that partisan colleagues are sent packets of suggested press releases or "talking points" for constituent meetings in their districts; they help to organize "town meetings" in Members' districts around the country to publicize the party's agenda or a specific priority, such as health care or education; they sponsor party "retreats" to discuss issues and assess the party's public image; they create "theme teams" to craft party messages that might be raised during the one-minute, morning hour, or special order period in the House; they conduct surveys of party colleagues to discern their policy preferences; they establish websites that highlight and distribute party images and issues to users; and they organize task forces or issue teams to formulate party programs and to develop strategies for communicating these programs to the public.

In 1954, Eisenhower articulated the domino theory in his outlook towards communism in Southeast Asia and also in Central America. He believed that if the communists were allowed to prevail in Vietnam, this would cause a succession of countries to fall to communism, from Laos through Malaysia and Indonesia ultimately to India. Likewise, the fall of Guatemala would end with the fall of neighboring Mexico. That year the loss of North Vietnam to the communists and the rejection of his proposed European Defence Community (EDC) were serious defeats, but he remained optimistic in his opposition to the spread of communism, saying "Long faces don't win wars". As he had threatened the French in their rejection of EDC, he afterwards moved to restore West Germany, as a full NATO partner.

Almost 60 years later, 80 year old career criminal Henry (Harry) James Burge claimed to have committed the theft, confessing to a newspaper, with the story being published in the Sunday Pictorial newspaper on 23 February 1958. He claimed to have carried out the robbery with two other men, although when discrepancies with a contemporaneous report in the Birmingham Post newspaper (the crime pre-dated written police reports) in his account of the means of entry and other items stolen, detectives decided there was no realistic possibility of a conviction and the case was closed. Burge claimed the cup had been melted down to make counterfeit half-crown coins, which matched known intelligence of the time, in which stolen silver was being used to forge coins which were then laundered through betting shops at a local racecourse, although Burge had no past history of forgery in a record of 42 previous convictions for which he had spent 42 years in prison. He had been further imprisoned in 1957 for seven years for theft from cars. Released in 1961, he died in 1964.

Thailand: The April 18 relay through Bangkok was the Olympic flame's first visit to Thailand. The relay covered just over 10 km, and included Bangkok's Chinatown. The torch was carried past Democracy Monument, Chitralada Palace and a number of other city landmarks. M.R. Narisa Chakrabongse, Green World Foundation (GWF) chairwoman, withdrew from the torch-running ceremony, protesting against China's actions in Tibet. Several hundred protesters were present, along with Olympic supporters. Thai authorities threatened to arrest foreign protesters and ban them from future entry into Thailand. A coalition of Thai human rights groups announced that it would organise a "small demonstration" during the relay, and several hundred people did indeed take part in protests, facing Beijing supporters. Intended torchbearer Mom Rajawongse Narissara Chakrabongse boycotted the relay, to protest against China's actions in Tibet. In Bangkok, students told the media that the Chinese Embassy provided them with transportation and gave them shirts to wear.

The amount of signal received from a distant transmission source is essentially geometric in nature due to the inverse square law, and this leads to the concept of effective area. This measures the performance of an antenna by comparing the amount of power it generates to the amount of power in the original signal, measured in terms of the signal's power density in Watts per square metre. A half-wave dipole has an effective area of 0.13 2. If more performance is needed, one cannot simply make the antenna larger. Although this would intercept more energy from the signal, due to the considerations above, it would decrease the output significantly due to it moving away from the resonant length. In roles where higher performance is needed, designers often use multiple elements combined together.

In this paper, he described a new system for storing and working with large databases. Instead of records being stored in some sort of linked list of free-form records as in CODASYL, Codd's idea was to use a "table" of fixed-length records, with each table used for a different type of entity. A linked-list system would be very inefficient when storing "sparse" databases where some of the data for any one record could be left empty. The relational model solved this by splitting the data into a series of normalized tables (or relations), with optional elements being moved out of the main table to where they would take up room only if needed. Data may be freely inserted, deleted and edited in these tables, with the DBMS doing whatever maintenance needed to present a table view to the application/user.

Charles Town was a hub of the deerskin trade, the basis of its early economy. Trade alliances with the Cherokee and Creek nations insured a steady supply of deer hides. Between 1699 and 1715, colonists exported an average of 54,000 deer skins annually to Europe through Charles Town. Between 1739 and 1761, the height of the deerskin trade era, an estimated 500,000 to 1,250,000 deer were slaughtered. During the same period, Charles Town records show an export of 5,239,350 pounds of deer skins. Deer skins were used in the production of men's fashionable and practical buckskin pantaloons, gloves, and book bindings.

The story takes place during three years (1933–35) of the Great Depression in the fictional "tired old town" of Maycomb, Alabama, the seat of Maycomb County. It focuses on six-year-old Jean Louise Finch (Scout), who lives with her older brother, Jem, and their widowed father, Atticus, a middle-aged lawyer. Jem and Scout befriend a boy named Dill, who visits Maycomb to stay with his aunt each summer. The three children are terrified of, and fascinated by, their neighbor, the reclusive Arthur "Boo" Radley. The adults of Maycomb are hesitant to talk about Boo, and, for many years few have seen him. The children feed one another's imagination with rumors about his appearance and reasons for remaining hidden, and they fantasize about how to get him out of his house. After two summers of friendship with Dill, Scout and Jem find that someone leaves them small gifts in a tree outside the Radley place. Several times the mysterious Boo makes gestures of affection to the children, but, to their disappointment, he never appears in person.

In the early 19th century, the Indigenous American woman Sacagawea, who would help translate for and guide the Lewis and Clark Expedition in the West, married the French trapper Toussaint Charbonneau. Most marriages between Europeans and Indigenous Americans were between European men and Indigenous American women. Depending on the kinship system of the woman's tribe, their children would be more or less easily assimilated into the tribe. Nations that had matrilineal systems, such as the Creek and Cherokee in the Southeast, gave the mixed-race children status in their mother's clans and tribes. If the tribe had a patrilineal system, like the Omaha, the children of white fathers were considered white. Unless they were specifically adopted into the tribe by an adult male, they could have no social status in it.

Historically, and since pre-Hispanic times, the Valley of Anahuac has been one of the most densely populated areas in Mexico. When the Federal District was created in 1824, the urban area of Mexico City extended approximately to the area of today's Cuauhtémoc borough. At the beginning of the 20th century, the elites began migrating to the south and west and soon the small towns of Mixcoac and San Ángel were incorporated by the growing conurbation. According to the 1921 census, 54.78% of the city's population was considered Mestizo (Indigenous mixed with European), 22.79% considered European, and 18.74% considered Indigenous. This was the last Mexican Census which asked people to self-identify themselves with an heritage other than Amerindian. However, the census had the particularity that, unlike racial/ethnic census in other countries, it was focused in the perception of cultural heritage rather than in a racial perception, leading to a good number of white people to identify with "Mixed heritage" due cultural influence. In 1921, Mexico City had less than one million inhabitants.

Translation of a text that is sung in vocal music for the purpose of singing in another language—sometimes called "singing translation"—is closely linked to translation of poetry because most vocal music, at least in the Western tradition, is set to verse, especially verse in regular patterns with rhyme. (Since the late 19th century, musical setting of prose and free verse has also been practiced in some art music, though popular music tends to remain conservative in its retention of stanzaic forms with or without refrains.) A rudimentary example of translating poetry for singing is church hymns, such as the German chorales translated into English by Catherine Winkworth.

Hunting is primarily regulated by state law; additional regulations are imposed through United States environmental law in the case of migratory birds and endangered species. Regulations vary widely from state to state and govern the areas, time periods, techniques and methods by which specific game animals may be hunted. Some states make a distinction between protected species and unprotected species (often vermin or varmints for which there are no hunting regulations). Hunters of protected species require a hunting license in all states, for which completion of a hunting safety course is sometimes a prerequisite.

Though almost any variety of acoustic mandolin might be adequate for Irish traditional music, virtually all Irish players prefer flat-backed instruments with oval sound holes to the Italian-style bowl-back mandolins or the carved-top mandolins with f-holes favoured by bluegrass mandolinists. The former are often too soft-toned to hold their own in a session (as well as having a tendency to not stay in place on the player's lap), whilst the latter tend to sound harsh and overbearing to the traditional ear. The f-hole mandolin, however, does come into its own in a traditional session, where its brighter tone cuts through the sonic clutter of a pub. Greatly preferred for formal performance and recording are flat-topped "Irish-style" mandolins (reminiscent of the WWI-era Martin Army-Navy mandolin) and carved (arch) top mandolins with oval soundholes, such as the Gibson A-style of the 1920s.

The Western family includes Parthian (Arsacid Pahlavi) and Middle Persian, while Bactrian, Sogdian, Khwarezmian, Saka, and Old Ossetic (Scytho-Sarmatian) fall under the Eastern category. The two languages of the Western group were linguistically very close to each other, but quite distinct from their eastern counterparts. On the other hand, the Eastern group was an areal entity whose languages retained some similarity to Avestan. They were inscribed in various Aramaic-derived alphabets which had ultimately evolved from the Achaemenid Imperial Aramaic script, though Bactrian was written using an adapted Greek script.

Since it was quite easy to stack interconnections (wires) inside the embedding matrix, the approach allowed designers to forget completely about the routing of wires (usually a time-consuming operation of PCB design): Anywhere the designer needs a connection, the machine will draw a wire in straight line from one location/pin to another. This led to very short design times (no complex algorithms to use even for high density designs) as well as reduced crosstalk (which is worse when wires run parallel to each other—which almost never happens in Multiwire), though the cost is too high to compete with cheaper PCB technologies when large quantities are needed.

By 1954, Olympic Games apparatus and events for both men and women had been standardized in modern format, and uniform grading structures (including a point system from 1 to 15) had been agreed upon. At this time, Soviet gymnasts astounded the world with highly disciplined and difficult performances, setting a precedent that continues. The new medium of television has helped publicize and initiate a modern age of gymnastics. Both men's and women's gymnastics now attract considerable international interest, and excellent gymnasts can be found on every continent. Nadia Comăneci received the first perfect score, at the 1976 Summer Olympics held in Montreal, Canada. She was coached in Romania by coach, (Hungarian ethnicity), Béla Károlyi. Comaneci scored four of her perfect tens on the uneven bars, two on the balance beam and one in the floor exercise. Even with Nadia's perfect scores, the Romanians lost the gold medal to the Soviet Union. Nevertheless, Comaneci became an Olympic icon.

The final is normally held the Saturday after the Premier League season finishes in May. The only seasons in recent times when this pattern was not followed were 1999–2000, when most rounds were played a few weeks earlier than normal as an experiment, and 2010–11 and 2012–13 when the FA Cup Final was played before the Premier League season had finished, to allow Wembley Stadium to be ready for the UEFA Champions League final, as well as in 2011–12 to allow England time to prepare for that summer's European Championships.

Several companies, refusing to pay the licensing fee or having been rejected by Nintendo, found ways to circumvent the console's authentication system. Most of these companies created circuits that used a voltage spike to temporarily disable the 10NES chip in the NES. A few unlicensed games released in Europe and Australia came in the form of a dongle that would be connected to a licensed game, in order to use the licensed game's 10NES chip for authentication. In order to combat unlicensed games, Nintendo of America threatened retailers who sold them with losing their supply of licensed titles. In addition, multiple revisions were made to the NES PCBs to prevent these games from working.

Lancashire has a mostly comprehensive system with four state grammar schools. Not including sixth form colleges, there are 77 state schools (not including Burnley's new schools) and 24 independent schools. The Clitheroe area has secondary modern schools. Sixth form provision is limited at most schools in most districts, with only Fylde and Lancaster districts having mostly sixth forms at schools. The rest depend on FE colleges and sixth form colleges, where they exist. South Ribble has the largest school population and Fylde the smallest (only three schools). Burnley's schools have had a new broom and have essentially been knocked down and started again in 2006. There are many Church of England and Catholic faith schools in Lancashire.

A distinction can be made between emotional episodes and emotional dispositions. Emotional dispositions are also comparable to character traits, where someone may be said to be generally disposed to experience certain emotions. For example, an irritable person is generally disposed to feel irritation more easily or quickly than others do. Finally, some theorists place emotions within a more general category of "affective states" where affective states can also include emotion-related phenomena such as pleasure and pain, motivational states (for example, hunger or curiosity), moods, dispositions and traits.

Airborne Interception radar (AI) was unreliable. The heavy fighting in the Battle of Britain had eaten up most of Fighter Command's resources, so there was little investment in night fighting. Bombers were flown with airborne search lights out of desperation[citation needed], but to little avail. Of greater potential was the GL (Gunlaying) radar and searchlights with fighter direction from RAF fighter control rooms to begin a GCI system (Ground Control-led Interception) under Group-level control (No. 10 Group RAF, No. 11 Group RAF and No. 12 Group RAF).

On 7 August 1998, al-Qaeda struck the U.S. embassies in Kenya and Tanzania, killing 224 people, including 12 Americans. In retaliation, U.S. President Bill Clinton launched Operation Infinite Reach, a bombing campaign in Sudan and Afghanistan against targets the U.S. asserted were associated with WIFJAJC, although others have questioned whether a pharmaceutical plant in Sudan was used as a chemical warfare plant. The plant produced much of the region's antimalarial drugs and around 50% of Sudan's pharmaceutical needs. The strikes failed to kill any leaders of WIFJAJC or the Taliban.

The Eastern Han, also known as the Later Han, formally began on 5 August 25, when Liu Xiu became Emperor Guangwu of Han. During the widespread rebellion against Wang Mang, the state of Goguryeo was free to raid Han's Korean commanderies; Han did not reaffirm its control over the region until AD 30. The Trưng Sisters of Vietnam rebelled against Han in AD 40. Their rebellion was crushed by Han general Ma Yuan (d. AD 49) in a campaign from AD 42–43. Wang Mang renewed hostilities against the Xiongnu, who were estranged from Han until their leader Bi (比), a rival claimant to the throne against his cousin Punu (蒲奴), submitted to Han as a tributary vassal in AD 50. This created two rival Xiongnu states: the Southern Xiongnu led by Bi, an ally of Han, and the Northern Xiongnu led by Punu, an enemy of Han.

Whether there are measurable changes in the sea level relative to the islands of Tuvalu is a contentious issue. There were problems associated with the pre-1993 sea level records from Funafuti which resulted in improvements in the recording technology to provide more reliable data for analysis. The degree of uncertainty as to estimates of sea level change relative to the islands of Tuvalu was reflected in the conclusions made in 2002 from the available data. The 2011 report of the Pacific Climate Change Science Program published by the Australian Government, concludes: "The sea-level rise near Tuvalu measured by satellite altimeters since 1993 is about 5 mm (0.2 in) per year."

Esoteric or Sufi interpretation attempts to unveil the inner meanings of the Quran. Sufism moves beyond the apparent (zahir) point of the verses and instead relates Quranic verses to the inner or esoteric (batin) and metaphysical dimensions of consciousness and existence. According to Sands, esoteric interpretations are more suggestive than declarative, they are allusions (isharat) rather than explanations (tafsir). They indicate possibilities as much as they demonstrate the insights of each writer.

In 1964, Paul VI created a Secretariat for non-Christians, later renamed the Pontifical Council for Interreligious Dialogue and a year later a new Secretariat (later Pontifical Council) for Dialogue with Non-Believers. This latter was in 1993 incorporated by Pope John Paul II in the Pontifical Council for Culture, which he had established in 1982. In 1971, Paul VI created a papal office for economic development and catastrophic assistance. To foster common bonds with all persons of good will, he decreed an annual peace day to be celebrated on January first of every year. Trying to improve the condition of Christians behind the Iron Curtain, Paul VI engaged in dialogue with Communist authorities at several levels, receiving Foreign Minister Andrei Gromyko and Chairman of the Presidium of the Supreme Soviet Nikolai Podgorny in 1966 and 1967 in the Vatican. The situation of the Church in Hungary, Poland and Romania, improved during his pontificate.

Men's rhythmic gymnastics is related to both Men's artistic gymnastics and wushu martial arts. It emerged in Japan from stick gymnastics. Stick gymnastics has been taught and performed for many years with the aim of improving physical strength and health. Male athletes are judged on some of the same physical abilities and skills as their female counterparts, such as hand/body-eye co-ordination, but tumbling, strength, power, and martial arts skills are the main focus, as opposed to flexibility and dance in women's rhythmic gymnastics. There are a growing number of participants, competing alone and on a team; it is most popular in Asia, especially in Japan where high school and university teams compete fiercely. As of 2002[update], there were 1000 men's rhythmic gymnasts in Japan.[citation needed]
