EAST LANSING, Mich. — Why do so many beginning teachers quit the profession or change schools? Surprising new research finds it’s not a heavy workload or lack of resources that has the most significant effect, but instead the relationship between teachers and their principal.
Peter Youngs, associate professor of educational policy at Michigan State University and lead investigator on the study, said the findings reinforce the need for principals to serve as strong, supportive leaders in their schools. (more…)
The most prestigious peer-reviewed journals in the world, such as Cell, Nature, Science, and the Journal of the American Medical Association (JAMA), have less and less influence amongst scientists, according to a paper co-authored by Vincent Larivière, a professor at the University of Montreal’s School of Library and Information Sciences. He questions the relationship between journal “impact factor” and number of citations subsequently received by papers.
“In 1990, 45% of the top 5% most cited articles were published in the top 5% highest impact factor journals. In 2009, this rate was only 36%,” Larivière said. “This means that the most cited articles are published less exclusively in high impact factor journals.” The proportion of these articles published in major scholarly journals has sharply declined over the last twenty years. His study was based on a sample of more than 820 million citations and 25 million articles published between 1902 and 2009. The findings were published in the Journal of the American Society for Information Science and Technology. (more…)
