FDA Goes for Genomic Sequencing in Fight Vs Foodborne Pathogens, Food-Safety Reform Delayed

The Food and Drug Administration (FDA) is harnessing the scientific expertise of the University of California, Davis to sequence the genomes of 100,000 types and subtypes of deadly foodborne bacteria to help it corral contamination outbreaks, such as the multistate Listeria contamination last year that killed 25 and sickened over a hundred. The announcement is good news to the public, food advocates, as well as conscientious restaurant owners who employ workers with food handler certification or food safety certification training, who all have relied on traditional, low-tech measures to help prevent and contain foodborne-illness outbreaks. Also being pressed into service are the Centers for Disease Control and Prevention (CDC) and Agilent Technologies Inc., a chemical analysis/engineering company based in Santa Clara, Calif. Once the genetic sequencing is completed, the results will be posted in a public database maintained by the National Institutes of Health's National Center for Biotechnology Information. "Right now, we spend a lot of time after an outbreak trying to figure out what country is it from, and how is it spreading," said Dr. Steven Musser, director of the FDA's office of regulatory science for food safety. He noted that the initiative is similar to the DNA information maintained by the Federal Bureau of Investigation for investigating crimes. "If we had this genetic sequence already, we could know immediately that the salmonella probably came from India, and we could have responded much more quickly," Dr. Musser pointed out, referring to this year's salmonella outbreak in tuna, which came from a plant in India. Lacking a genetic database for pathogens, FDA instead took almost two months to confirm that sushi was the culprit. According to the FDA, the new database has the potential to slash the typical public-health response time in foodborne illness outbreaks to days instead of weeks. But while food safety is moving fast on the tracking front, there is little movement on the prevention front. Last year President Obama signed into law a bill to overhaul food safety in the United States, a sweeping food-policy change not seen in 70 years. But not much has happened since then-to the great frustration of the public and food advocates. The Food Safety Modernization Act updates the basic way the Food and Drug Administration (FDA) carries out its role: from an agency that responds to incidents of contaminated or adulterated food to one that stops contamination or adulteration from manifesting in the first place. The act empowers the agency to compel food recalls and to employ additional food-safety inspectors. Despite bipartisan endorsement in Congress and near universal support from the public health groups and the food industry, implementation of the new law has gotten stuck in procedural muck. Regulations implementing the law have not been approved, the upshot of lack of major action by the Office of Management and Budget (OMB), which is still evaluating the rules' effectiveness and alignment with administration policies. The regulations have been with OMB for seven months, four months past its deadline. OMB spokeswoman Moira Mack explained that public-safety rules require extensive review, which, she said, is exactly what OMB is doing. "The administration is working as expeditiously as possible to implement this legislation we fought so hard for. When it comes to rules with this degree of importance and complexity, it is critical that we get it right."

Tips How to Create and Teach a Pre Calculus Course

It is essential to have a pre calculus course that gathers all the topics covered in pre calculus just in one subject. This subject is overwhelming for many students. This is because they have to have thorough knowledge of several other subjects. The student should have solid base in algebra, geometry, and trigonometry. Special attention should be given to binomial theorem, conic sections, complex numbers and real numbers. Calculus is the branch of science that deals with rates of change. In algebra the student is taught about a function that represents a physical quantity, for example the amount of water in a tank relative to time. However; in calculus the interest is in the rate at which water is changing in a tank relative to time. One can see clearly how calculus completes the picture after algebra. Algebra answers one question and calculus answers a different question and they together give the whole picture. Calculus requires that the student have a good knowledge of algebra. A good tactic in teaching algebra in a pre calculus course is to point out the points that most students have problems with. Students studying algebra have particular problems with exponents and logarithms. It is good to use calculators to do laboratory experiments to get the students to understand exponents. For example the teacher can ask the students to use their calculators to find the exponents of 0, 2, 4, 100, and 200. The students will see how the change of the output gets very steep with small changes in the input. Then the teacher should ask the students to use their calculator to plot the graph of an exponent function. The students should examine the curve and see how little change in input cause a dramatic change in output. The same experiments should be done with logarithms. The teacher should choose a base and chooses values to take the logarithms of. The teacher should let students try forbidden values like negative values and see how the calculator responds. Also the teacher should let the students plot a logarithmic function and spot the forbidden values on the graph. Geometry is very important for calculus. The most important concept in geometry related to calculus is the area. The student should see how he can find the area of a shape by slicing it into simpler shapes and then adding the individual areas of these shapes. The student should see that we can simplify the circumference calculation by simplifying the circle by considering it a polygon. This simplification causes some error margin. However; the error decreases as we increase the number of sides of the polygon. The error becomes null when the number of sides become infinite. Although the need of trigonometry does not come at the beginning of a calculus class students should know the basic trigonometric functions and their relations. The students should appreciate that the cosine is a sine with a shift and the sine is a cosine with a shift. They should see their graphs simultaneously on a calculator. After knowing what should be taught in a pre calculus course one should choose a suitable textbook to be assigned to the class. Choosing a textbook is not an easy task. Some students would not do well in a course only because the textbook was not friendly or easy to understand. The textbook should be easy to understand with lots of examples and starts right from the beginning. The teacher explanation for concepts should be in close resemblance to the textbook so the students do not get confused. For every new concept or idea the teacher should solve several demonstration problems. This really allows the student to follow up with the ideas discussed in class. The teacher should allow the students to ask as many questions as needed to understand. The students should know that their questions are welcome and that it is important for the teacher that they understand the concepts. Throughout the course the students should do laboratory experiments using calculators to dissolve the concepts. They would need an algebra calculator, a basic scientific calculator and a graphing calculator. There are many new innovative software calculators like kinematics calculators and many others. These calculators allow the teacher to be creative in how he creates mathematics laboratory experiments.

Synchronous Vs Asynchronous Technologies - Tools For Distance Learning

Computers and the internet are becoming more relevant to distance learning (and traditional) courses, but some of the tools available for today's distance courses are not particularly futuristic or advanced. By looking at synchronous and asynchronous technologies, this article aims to give an overview of all the ways students can be taught and instructed on distance learning courses today. The two primary synchronous methods for distance learning are Videoconferencing and Web Conferencing. Videoconferencing in education allows two sets of people (usually a lecturer and group, or two groups, or one on one) to see each other and communicate in real time. In simple terms these are very similar to traditional conferences, lectures, or seminars, but the method is notable for the savings made on travel and the great distances that can be crossed with little delay. Additionally, with the advent of broadband, videoconferencing is now often done over the internet. Web conferencing is similar, though with less of a focus on speaking and seeing others and instead using an instant message style format. The principals are the same, but web conferencing is often preferred today due to the technology being cheaper (no cameras or microphones), and a speedier connection between users. Today, one of the regarded benefits of distance learning is the fact that the student can complete his/her studies where and when she wants to. Consequently, courses have been adapted to accommodate asynchronous technologies. In the past, audio and video cassettes containing instructions by institutions and lecturers were posted to students, however today, equivalent instruction can be e-mailed as easily with the necessary media, photos, or texts attached. Further asynchronous advancements have been made with the introduction of forums and wikis to distance education. Forums are instantly communal and very simple to use, allowing work to be viewed and discussed easily. Separate threads can be established by each user and can concern texts, problems, classes, and fun issues - as well as being easy to monitor by a teacher or lecturer. Wikis follow a similar principal, but are typically intended for available viewing of outside users. They can be a good incentive for students to work together and maintain an informative collection of simple factual web pages, with the intention of teaching students to strive in the quality of their work - particularly when they know it can be viewed by the public.

5 Tips For Selecting an Online Graduate Program

So here are some search tips which you can follow while finding online graduate program. Validity of the online program: It is necessary to examine the validity of the online education program and this is the foremost step before listing top colleges and moreover it is also important to find out the legitimacy of the institution. (adsbygoogle = window.adsbygoogle || []).push({}); Online institutions and its accreditation: The educational qualification of the student depends on the course of study he/she has pursued. If the institution has no accreditation, then its degree programs won't be recognized anywhere. For any tuition reimbursement it is an important criterion to choose an accredited institution. Operational online institutes: The choice of the online institution for graduate program is operational and so it is always better to go for established institutions than any new one. For operational programs it will be impossible for you to get graduate program classes and technical support and it will be difficult to continue with your studies. Technologically compatible: One of the most important aspects of the online education is the technical compatibility and without technology it is difficult to carry on online studies. So before choosing any institutions it is important to verify the technological support of the program and then decide. Learned faculties: Learned faculties are the most essentials in online education programs and even in offline programs. However, offline you can visit the college or can ask the senior members, but online you have to verify the quality of the professors the programs have employed. If the faculty staffs are learned and professionals, the educators will deliver better quality of education and the better will be the online graduate program making students as per industry standards.
