A journal has retracted a paper about 3D imaging after concluding the authors used equations from another researcher without attribution — and has conveniently included a detailed editorial explaining exactly what happened.
It’s rare for us to see a journal be so transparent in explaining what went wrong with one of its papers, so we’re thanking Stuart Granshaw, from Denbighshire in Wales, UK, the editor of The Photogrammetric Record, for“doing the right thing.”
Fred Walumbwa, a management researcher with eight seven retractions, has received three expressions of concern from two journals after he failed to provide raw data following an investigation into potential errors.
In the past, Walumbwa has said he only keeps data until his papers are published, but a lack of raw data has become a common theme in his notices, which now also include four corrections, and one other EOC (making a new total of four). There are no standard rules about how long to store raw data, but one journal that issued two of the new EOCs has since updated its submission policy to require that authors keep data for at least five years.
Walumbwa currently works at Florida International University. When concerns about the statistics were raised about five of his papers in Personnel Psychology, the journal conducted an investigation that led to flagging two of those articles, the expression of concern explains:
The authors of a paper on a new probiotic strain of bacteria found in pig feces have retracted it from Animal Science Journal after discovering some of the bacteria might have been contaminated.
Readers likely know by now how easy it is for this to happen, as we frequently report on retractions due to similar reasons. Like other instances of mistaken cell identity, the authors of this 2013 paper realized the mistake following further tests of the bacteria used in the experiment.
Plant scientist Jorge Vivanco has earned his seventh retraction, after an investigation found data from soil samples were “intentionally fabricated by a third party.”
Vivanco and his former postdoc Harsh Bais made a name for themselves by discovering the secret behind a nasty invasive plant: It secretes a harmful form of catechin, which kills everything around it, suggesting it could serve as a new herbicide. The findings earned the researchers a story in the New York Times.
In the newly retracted paper, published in 2005, first author Laura Perry — then a postdoc at Colorado State University — further explored the role of the plant-killer, working with Vivanco as the last author. However, when a team working in the building next door had trouble finding catechin in their samples, Perry took another look, and concluded that her samples had been tampered with.
A 2006 paper investigating the effects of docosahexaenoic acid (DHA) and celecoxib on prostate cancer cells has been retracted because it appears to contain panels that were duplicated, and the authors could not provide the raw data to show otherwise.
This is the second paper the authors have lost because they couldn’t furnish the original data to defend their work against allegations of image manipulation. The reason: the Institute for Cancer Prevention in New York, where the authors did the work, shut its doors abruptly in 2004, co-author Bhagavathi A. Narayanan told us. (The institute closed thanks to $5.7 million in grant that was misspent, the New York Post reported at the time.)
Recently, some of Narayanan’s papers have been questioned on PubPeer; her work has been the subject of an investigation at New York University, where Narayanan is now based.
Narayanan told us that the criticism of their work has deeply affected her and her co-authors:
Former accounting professor James Hunton has added a 33rd retraction to his total, solidifying his position at #10 on our leaderboard.
Hunton’s official total is 33.5, since one journal retracted only one section of a paper, making it a “partial” retraction. Most of those retractions came last year, the fallout from an investigation at Bentley University which concluded that the accounting researcher had committed misconduct. Hunton resigned from the university in 2012 after his first retraction, citing family matters.
A journal is retracting three papers — including one that is highly cited — after learning the reviewers that recommended publication had conflicts of interest.
This is a case of family values gone awry: The author common to all papers is Cheng-Wu Chen at the National Kaohsiung Marine University in Taiwan, the twin brother of one Peter Chen, who was a the center of a peer review ring that SAGE busted in 2014 (and holder of the number #3 spot on our leaderboard). Cheng-Wu Chen apparently wasn’t an innocent bystander in that episode: Of the 60 retracted papers by SAGE, Cheng-Wu Chen was a co-author on 21.
A peer reviewer apparently thought portions of a manuscript he was reviewing were so good he wanted them for himself.
Substantial sections of a paper that Junwei Di reviewed appear in his own paper on a method for making tiny particles of silver to precise specifications. Di is a chemist at Soochow University in China. The journal has banned Di from submitting papers or serving as a peer reviewer “for a certain time.”
When a researcher encountered two papers that suggested moonlight has biological effects — on both plants and humans — he took a second look at the data, and came to different conclusions. That was the easy part — getting the word out about his negative findings, however, was much more difficult.
When Jean-Luc Margot, a professor in the departments of Earth, Planetary & Space Sciences and Physics & Astronomy at the University of California, Los Angeles, tried to submit his reanalysis to the journals that published the original papers, both rejected it; after multiple attempts, his work ended up in different publications.
Disagreements are common but crucial in science; like they say, friction makes fire. Journals are inherently disinterested in negative findings — but should it take more than a year, in one instance, to publish an alternative interpretation to somewhat speculative findings that, at first glance, seem difficult to believe? Especially when they contain such obvious methodological issues such as presenting only a handful of data points linking biological activity to the full moon, or ignore significant confounders?
Margot did not expect to have such a difficult experience with the journals — including Biology Letters, which published the study suggesting that a plant relied on the full moon to survive: Continue reading Why publishing negative findings is hard
