65, of Tupelo, has other ways of attaining new rocks. “I go on some field trips, but not many. Some of it is mail order. Some of it is swap |
like that rock. It’s got a nice, purple glimmer to it.” Byzet got into collecting as a child, when a neighbor introduced him to the hobby. He didn’t know it |
at the time, but that neighbor and her husband were responsible for a semi-precious stone exhibit at a San Diego museum. “She gave me my first collection,” Byzet said. Rocks |
lost their appeal for Byzet over the years, and he put them away until about three or four years ago, when he saw them again through youthful eyes. “My grandson |
was up here and saw some and he drew me back into it. I’ve been enjoying it. I’ve learned a lot. You can’t help but learn if you do it |
There are classes on faceting, as well as tips on how to collect, identify and display collections. There’s also plenty of plain, old give-and-take between the members, said Robert Langford, |
64, a professional geologist from Saltillo. “I just love geology,” he said, “and it’s a good opportunity to meet with people who have the same interests.” Like Roberts, Langford focuses |
on fossils, and that fascination has trickled down to two of his daughters. “They have their own collections,” he said. “They have a good time collecting fossils.” The hobby has |
come full circle for Langford, who was helped and encouraged by his mother when he was a teenager. “It’s about hunting and finding and trying to figure out what it |
was,” he said. “From a family standpoint, it’s a great hobby.” Treasure comes in all shapes and sizes, and people deal with it in different ways. A lot of Langford’s |
collection is packed away in boxes, while Byzet combines woodworking with rock hounding to create display cases out of black walnut. “Everybody comes at it their own way,” Roberts said. |
GloMax®-Multi Jr Method for DNA Quantitation Using Hoechst 33258 - Comments & Ratings Quantitation of DNA is an important step for many practices in molecular biology. Common techniques that use |
DNA, such as sequencing, cDNA synthesis and cloning, RNA transcription, transfection, nucleic acid labeling (e.g., random prime labeling), etc., all benefit from a defined template concentration. Failure to produce results |
from these techniques sometimes can be attributed to an incorrect estimate of the DNA template used. The concentration of a nucleic acid most commonly is measured by UV absorbance at |
As a policy, Python doesn't run user-specified code on startup of Python programs. (Only interactive sessions execute the script specified in the PYTHONSTARTUP environment variable if it exists). However, some programs or sites may find it convenient to allow users |
to have a standard customization file, which gets run when a program requests it. This module implements such a mechanism. A program that wishes to use the mechanism must execute the statement The user module looks for a file .pythonrc.py |
in the user's home directory and if it can be opened, executes it (using execfile()) in its own (the module user's) global namespace. Errors during this phase are not caught; that's up to the program that imports the user module, |
if it wishes. The home directory is assumed to be named by the HOME environment variable; if this is not set, the current directory is used. The user's .pythonrc.py could conceivably test for sys.version if it wishes to do different |
things depending on the Python version. A warning to users: be very conservative in what you place in your .pythonrc.py file. Since you don't know which programs will use it, changing the behavior of standard modules or functions is generally |
not a good idea. A suggestion for programmers who wish to use this mechanism: a simple way to let users specify options for your package is to have them define variables in their .pythonrc.py file that you test in your |
module. For example, a module spam that has a verbosity level can look for a variable user.spam_verbose, as follows: import user verbose = bool(getattr(user, "spam_verbose", 0)) (The three-argument form of getattr() is used in case the user has not defined |
spam_verbose in their Programs with extensive customization needs are better off reading a program-specific customization file. Programs with security or privacy concerns should not import this module; a user can easily break into a program by placing arbitrary code in |
Preterm labor occurs between the 20th and 37th week of pregnancy. This labor includes both uterine contractions and cervical changes. A full-term pregnancy lasts 38-42 weeks but preterm labor can |
lead to early delivery. Infants born before 37 weeks are considered premature. In most cases, the cause is of preterm labor is unknown. Some preterm labor is associated with preterm |
premature rupture of membranes (PPROM). PPROM is the rupture of both the amniotic sac and chorion membranes. It generally occurs at least one hour before labor begins. The chance of |
preterm-labor is greatest in women under the 18 years or over 35 years. Other maternal factors that may increase the chance of preterm labor include: - Low socioeconomic status - |
Lack of prenatal care and social support - Being underweight or obese before becoming pregnant - Physical, sexual, or emotional abuse - Severe depression or anxiety - High blood pressure |
- Clotting disorders - Hormonal imbalance - Certain medications to treat health problems or exposure to diethylstilbestrol (DES) - Illicit drug use - Alcohol use Pregnancy complications that may increase |
your risk of preterm labor include: - Placental abruption - Premature rupture of the membranes - Carrying more than one baby - Vaginal bleeding after 16 weeks, or during more |
than one trimester - Infection in the cervix, uterus, vagina, or urinary tract including STDs - Being pregnant with a single fetus after in vitro fertilization (IVF) - Presence of |
a retained intrauterine device - Incompetent cervix - Too much or too little fluid surrounding the baby - Surgery on your abdomen during pregnancy - Amniotic fluid infection - Intrauterine |
fetal death - Intrauterine growth delay - Birth defects in the baby Other factors associated with an increased chance of preterm labor include: - History of one or more spontaneous |
second-trimester abortions - Less than six months between giving birth and the beginning of the next pregnancy - A previous preterm birth - Uterine fibroids - Abnormally shaped uterus Symptoms |
may include: - Abdominal pain that feels something like menstrual cramps - Dull pain in the lower back - Pressure in the pelvis and tightening in the thighs - Vaginal |
bleeding or spotting, or watery discharge Your doctor will ask about your symptoms and medical history. A physical exam will be done. Your doctor may recommend tests to check your |
cervix and membranes have ruptured. An ultrasound will help your doctor see internal structures and the baby. Fluids in the cervix will also be tested for sign of labor progression. |
A tocometer may be placed to help monitor contractions. Treatment will depend on your baby's development, especially the growth of the lungs. If your doctor believes the baby is ready, |
the labor may be allowed to continue. If the baby is not ready to be delivered, your doctor may try to stop the labor. Stopping labor is a complicated process |
and may not always work. Some treatment options may include: - Tocolytics—may delay labor for a few days - Corticosteroids—to help the baby's lungs develop - Antibiotics—if an infection is |
suspected or present To help reduce your chance of preterm labor, take the following steps: - Get the proper prenatal care throughout your entire pregnancy. - Eat a healthy, balanced |
diet with plenty of fruits, vegetables and whole grains. - Avoid smoking, alcohol, and drugs. - Keep chronic diseases under control. - Stay active during your pregnancy. Your doctor can |
give you exercise guidelines that are right for you. - If you are at high-risk for premature birth, talk to your doctor about progesterone therapy. - Reviewer: Andrea Chisholm, MD; |

water. That having been said, most Labs can be taught to swim quickly and easily, and a few simple lessons can lead to hours of enjoyment for both you and your dog. There are a number of reasons to teach your Lab to swim while he’s still a pup. For one thing, it’s easier on the dog. A large dog |
has a lot of body weight to manage in the water, and for a dog new to swimming, this can increase the slope of the learning curve. Puppies, because of their small size, have an easier time. See 7.5 week old Labrador pups go to the water for the first time Even before you teach your Lab to swim, you |
can start off on the right foot by building his confidence around water. Take your dog for a walk around the local pond or lake. Encourage any interest that your dog shows in the water with verbal praise. If he is willing to get his feet wet, encourage him to do so and praise him when he does. Simple preliminaries |
like this lay a strong foundation for you because you teach the dog that there is no reason to fear water.

Fixing Math Education 2 AKA "Drill-n-Kill" vs "Inquiry Based" AKA "Traditional" vs "Progressive" Notice how some terms just naturally sound better than others? Does that have anything to do with the substance of the ideas? So there's really no general agreement on what constructivism is. Some people argue it's not |
curriculum or pedagogy, it's brain science. I simply use it to refer to those approaches of teaching mathematics that require students to develop their own mathematics from scratch. It might include "Problem Solving," "Discovery Learning," and "Inquiry-based Learning (IBL)." My apologies to those who will claim that I ... |
to their pet definitions here. But there do seem to be two general camps. On the one hand we have those who think students should learn efficient, time-tested methods of solving problems, and learn them to mastery (automation). These I call "traditionalists." On the other hand, we have those who |
emphasize that students should learn to think creatively, develop strategies to solve novel problems, and develop deep insights into mathematics. These I call "constructivists." The answer is actually simple. We need both. However, when sacrifices must be made, there is one approach that is essential, and one that is m... |

your head" and give the solution, not only without a calculator but even without a pencil. The kinds of thinking and understanding that were required differed from what is expected today, because the skill set expected of an educated person has changed. So in those days, being able to carry |
sums in your head was far more important than, say, sketching the graph of an exponential function. In honest debate, we must realize that "Back-to-the-Basics" or "traditional education" does not imply restricting ourselves to the content or objectives of a bygone era. The primary features of the traditional method inc... |

The traditional method r... |

And yes, even educators from Singapore, whose students smoke the Americans in international tests, are looking with envy at the creativity of some of our students. This demonstrates that a ... |
to the essential objectives may not produce all the results that are desirable. It is well documented in cognitive science that the brain has a limited capacity to manipulate objects in "working memory." It is often said that we cannot process more than seven memory objects at once, which supposedly |
explains why phone numbers have seven digits (only now they have 10, but that's OK, because the phone remembers all the numbers for us). The working memory is where problem solving and creative activities take place. The working memory can access permanent memory for information it needs. However, any new |
information that must be taken in to solve a problem must occupy space in the working memory, thus taking away from the space available for creative activity. That is why we quickly become frustrated when trying to follow assembly instructions that include many terms with which we are not familiar. |
Even if the actual steps in the process are simple, if they involve several terms that are not defined in our permanent memory, those terms require space in our working memory which is then not available for solving the problem. This explains why the pedagogic fad of "learning to learn" |
is a failure. We do indeed need skills for learning--but such skills are utterly dependent on a reliable bank of information which can be accessed instantly and does not require the use of working memory. The first step in problem solving or creativity must be putting as much relevant information |
A continuation of our predictions of big issues for 2011... Don’t expect the debates on teaching quality to end anytime soon. We suspect that data from test scores (a la the Los Angeles Times series of 2010) will continue to |
be used to determine a teacher’s effectiveness in the classroom. Beyond the problems of relying on one strand of data, this approach also reinforces the unfortunate lack of attention given to the early grades, since statewide tests are typically, and |
appropriately, not administered to children younger than 8 or 9. This disregard of teacher quality in the early years has led to a sorry state in many schools. A 2007 study published in Science, for example, showed that only 10 |
percent of poor children experience high-quality instruction throughout their elementary school years. So we applaud the focus on effective teaching in principle. What we wish is that it would go much deeper. Teachers and principals should be assessing the quality |
of their instruction using research-based tools that feed on most teachers’ desires to improve. Early childhood programs know this already. Tools like the Classroom Assessment Scoring System (CLASS) are in use throughout the Head Start program and in several state-wide |
pre-k programs as well. (In fact, they may become a tool for determining which Head Start programs have to re-compete for funds.) These research-based tools use data from minute-by-minute observations of classroom interactions to determine where teachers excel and where |
they need to change their approach. According to anecdotal reports from teachers in these programs, the observational records are incredibly helpful in honing their craft. Could this be the year for elementary and secondary schools to wake up to the |

too difficult to manage? With all these starts and stops over years and decades, you may think: What’s the point of trying? Or maybe you’ve given up and resolved to just accept poor health as part of your life. Well, the inability to “stick with it” has many facets, some of which you may not be able to control. In |
fact, research shows that the self-control needed to succeed in many of these cases may be a limited resource.
