40 years of federal nutrition research fatally flawed Four decades of nutrition research funded by the Centers for Disease Control and Prevention (CDC) may be invalid because the method used to collect the data was seriously flawed, according to a new study by the Arnold School of Public Health at the University of South Carolina. The study, led by Arnold School exercise scientist and epidemiologist Edward Archer, has demonstrated significant limitations in the measurement protocols used in the National Health and Nutrition Examination Survey (NHANES). The findings, published in PLOS ONE (The Public Library of Science), reveal that a majority of the nutrition data collected by the NHANES are not "physiologically credible," Archer said. These results suggest that without valid population-level data, speculations regarding the role of energy intake in the rise in the prevalence of obesity are without empirical support, he said. The NHANES is the most comprehensive compilation of data on the health of children and adults in the United States.

Online Learning: An Intensive Bachelor's Level Computer Science Program Curriculum, Part II Last month, we published a piece providing a basic template for a bachelor’s level computer science curriculum composed entirely from college or university courses that are freely available online. To date, this has been the most popular post on the blog, and we received a ton of great feedback, both positive and negative, in the comments and from around the web. The original post was based on a learning plan that I had worked out for myself after I jumped into the study of programming and computer science just over a year ago on something of a whim. As I’ve mentioned before, I do not have any formal background in computer science beyond the handful of courses from this list that I have worked through myself. However, I do have years of experience in teaching and in curriculum design for natural and foreign language acquisition at the college level, and consulted the computer science curricula from a number of universities around the country when putting the plan together.

The Scientific Revolution - Definition - Concept - History Professor Robert A. Hatch - University of Florida Working Definition: By tradition, the "Scientific Revolution" refers to historical changes in thought & belief, to changes in social & institutional organization, that unfolded in Europe between roughly 1550-1700; beginning with Nicholas Copernicus (1473-1543), who asserted a heliocentric (sun-centered) cosmos, it ended with Isaac Newton (1642-1727), who proposed universal laws and a Mechanical Universe. Was there such a thing as the 'Scientific Revolution' -- and if the question makes sense, what is it, or what was it? Better still, what do historians mean when they speak of the 'Scientific Revolution'? What follows is a modest attempt to clarify basic issues and suggest others that are less obvious. Which is to say, the Scientific Revolution provides an excellent exercise for thinking about how historical periodizations emerge, develop, and mature. All students of history confront these kinds of issues.
