How much self-plagiarism, aka duplication, is too much? Duplication is a frequent reason for the retractions we cover. Such duplication retractions are so common that we don’t get to most of them. While many have argued that duplication pollutes the literature, and can bias meta-analyses when the same study ends up being counted more than once, others say the need to come up with new ways to say the same thing is a waste of time. (That doesn’t explain why some scientists don’t just put their old words in quotes and cite them, but we digress.) Appropriately, the Committee on Publication Ethics is taking up the issue at their regular forum tomorrow, using new guidelines produced by BioMedCentral as a starting point.
Here’s an excerpt: The guidelines also suggest that editors should only go back to 2004 as long as the duplication doesn’t involve data. COPE is looking for responses to these guidelines, so leave a comment on their site. Like this: Like Loading... Reactions to everyday stressors predict future health. Contrary to popular perception, stressors don't cause health problems -- it's people's reactions to the stressors that determine whether they will suffer health consequences, according to researchers at Penn State. "Our research shows that how you react to what happens in your life today predicts your chronic health conditions and 10 years in the future, independent of your current health and your future stress," said David Almeida, professor of human development and family studies.
"For example, if you have a lot of work to do today and you are really grumpy because of it, then you are more likely to suffer negative health consequences 10 years from now than someone who also has a lot of work to do today, but doesn't let it bother her. " Specifically, the researchers surveyed by phone 2,000 individuals every night for eight consecutive nights regarding what had happened to them in the previous 24 hours. "We did this 10 years ago in 1995 and again in 2005," Almeida said. 1-s2.0-S0167876005002886-main.pdf (application/pdf Object) International Journal of Psychophysiology - The effect of acute stress on memory depends on word valence. Abstract The present study investigated the effect of acute stress on working memory and memory for neutral, emotionally negative, and emotionally positive words in healthy undergraduates.
Participants (N = 60) were exposed to either the Trier Social Stress Test (stress group) or a non-stressful task (control group). Analyses of salivary cortisol samples taken throughout the study showed elevated glucocorticoid levels after the experimental manipulation in the stress group, but not in the control group. Recall performance was impaired in the stress group, but only so for neutral words.
