“Authors, please call us. Pretty please? OK, we’re going to retract your paper!”

dovelogoThe title of this post isn’t exactly how the one-sided conversation between the editors of Neuropsychiatric Disease and Treatment and a group of researchers went. But it seems likely it was pretty close.

Here’s an expression of concern for “A cross-sectional study on perception of stigma by Chinese schizophrenia patients:” Continue reading “Authors, please call us. Pretty please? OK, we’re going to retract your paper!”

“Positivity ratio” research now subject to an expression of concern

An expression of concern has been issued for the second of three papers on the idea that, if you have three positive emotions for every negative one, you will be more successful in life.

Psychologist Barbara Fredrickson, of the University of North Carolina, Chapel Hill, has spent the last decade building a brand around this ratio, initially described by a mathematical equation based on fluid dynamics by mathematician Marcial Losada. You can read our coverage of the debunking of that equation, presented in a 1999 paper that has been cited nearly 1,700 times, here.

Nick Brown, co-author with Alan Sokal on the paper that discredited the Losada equation, has written a blog post on the current state of affairs. He also got in touch with us regarding the expression of concern for a 2004 article in American Behavioral Scientist that he had also questioned, “The Role of Positivity and Connectivity in the Performance of Business Teams: A Nonlinear Dynamic Model”: Continue reading “Positivity ratio” research now subject to an expression of concern

dovelogoA group of researchers in China has lost their paper on liver cancer after the first author admitted to duplication, also known, inelegantly, as self-plagiarism.

Yogurt to be kidding me: Five articles plagiarized in one retracted paper

After typing up 96 citations, researchers from the National Institute for Digestive Diseases, I.R.C.C.S. “S. de Bellis,” in Bari, Italy, apparently ran out of steam for the last five, earning themselves a retraction for plagiarism in a literature review of the effects of probiotics on intestinal cancer.

Here’s the notice for “Intestinal Microbiota, Probiotics and Human Gastrointestinal Cancers,” from the Journal of Gastrointestinal Cancer: Continue reading Yogurt to be kidding me: Five articles plagiarized in one retracted paper

Rice researcher in ethics scrape threatens journal with lawsuit over coming retraction

Guangwen Tang, a rice researcher at Tufts University, landed in hot water in 2012 after her team was accused of feeding Chinese children genetically modified Golden Rice without having obtained informed consent from the parents.

Now, she’s suing both Tufts and the American Journal of Clinical Nutrition, which reportedly is retracting a paper, “ß-carotene in Golden Rice is as good as p-carotene in oil at providing vitamin A to children,” based on the federally funded research, claiming that the retraction would constitute defamation. (That retraction hasn’t happened yet.)

This isn’t the first time we’ve heard the retraction = defamation line. Readers might remember Ariel Fernandez, who threatened to sue us for writing about an expression of concern. Maybe a course on the Streisand Effect should be mandatory for PhD students?
