“How many and which ant species are being accidentally moved around the world?,” published in 2013, has been retracted because the authors “used a wrong list of species and omitted to include a reference.”

The authors claim that this affected the magnitude of the issue, but not the overall conclusion.

The paper was written up by the press several times, including by the BBC, though according to Thomson Scientific’s Web of Knowledge, it hasn’t been cited.

Here is the notice: Continue reading Who moved my ants? Species confusion sinks paper on invasive species

“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

ORI sanctions collaborator of Nobel winner Buck for data fabrication

ori logoThe Office of Research Integrity has sanctioned a former researcher in the lab of Linda Buck, winner of the 2004 Nobel Prize in Physiology or Medicine, for falsifying data in two papers written with the support of grants from the National Institutes of Health.

The researcher, Zou Zhihua, worked with Buck as a post-doc at Harvard and then at the Fred Hutchinson Cancer Research Center, in Seattle, Buck’s current home. After leaving there in 2005, he spent three years at the University of Texas Medical Branch in Galveston, and now appears to be a faculty member at Jilin University in China.

According to the report:

Sometimes, retractions seem to have a juicy back story, but the explanation proves tantalizingly out of reach.

Such is the case for a law review retraction on a paper about reparations for human rights violations. After someone complained that author Gentian Zyberi “had not done sufficient justice to the substantial contribution” they made, the complainant refused both a co-author credit and a rewrite of the passages in question, insisting instead on a full retraction.

Here’s the notice for “The International Court of Justice and applied forms of reparation for international human rights and humanitarian law violations”: Continue reading Law review paper yanked for lack of attribution despite offer of co-authorship

“Lack of experience and understanding” forces duplication retractions of liver cancer paper

Dennis Rottländer, who will also be returning prize money he was awarded for the research, worked in Uta C. Hoppe’s lab at the University of Cologne. Hoppe, now at University Hospital Salzburg, remains under investigation, according to a statement from the DFG.

Patient mix-up sinks prenatal supplement paper

This one seems like an honest mistake: a paper on dietary supplements during pregnancy has been retracted based on an error in data recording.

In the BMC Pregnancy & Childbirth paper, “Folic acid supplementation, dietary folate intake during pregnancy and risk for spontaneous preterm delivery: a prospective observational cohort study,” women for whom the researchers had no data on folic acid supplementation were classified as taking no supplements. Despite the error, the authors claim the overall conclusion remains the same: taking folic acid supplements didn’t protect women from preterm deliveries.

Here’s the retraction notice: Continue reading Patient mix-up sinks prenatal supplement paper
