Neuroscientist in Serbia set to notch 7th retraction amid investigation

Lidija Radenović

Amidst an ongoing investigation by the University of Belgrade in Serbia into allegations of duplication by neurobiologist Lidija Radenović, a journal is planning to retract another one of her papers.

Radenović has already racked up six retractions; Elinor Ben-Menachem, the chief editor of the journal, Acta Neurologica Scandinavica, confirmed her journal is planning to retract one paper co-authored by Radenović, but did not specify which one. After digging around on the journal’s website, we found only one paper co-authored by Radenović, which was 2005 study about the molecular changes that follow stroke. 

Ben-Menachem, who is based the University of Gothenburg in Sweden, said the retraction note for the paper is “not ready” yet, and declined to comment on the case in more detail, including the reason for retraction.

Does this scientific image look familiar? It’s from a catalog

cover (4)There’s something strange about a 2008 paper on the role of nicotine receptors in promoting lung cancer: One of the western blot analyses looks like a version of an image from a commercial catalog.

A commenter on PubPeer pointed out the similarities between an image in “Role of α7-nicotinic acetylcholine receptor in human non-small cell lung cancer proliferation,” which was published in Cell Proliferation, and one used to promote an enzyme sold by Cell Signaling Technology.

Unfortunately, if the images are indeed the same, we can’t tell for certain who copied from whom. But a representative of the company told us it generates its own images, and this one was likely created before the paper was published. The last author — for whom we’ve found three other retractions — denied that the paper copied the image.

Here’s the panel from the paper, which was published in 2008: Continue reading Does this scientific image look familiar? It’s from a catalog

Now this is transparent: Retraction for plagiarism earns 4-page editor’s note

The Photogrammetric Record

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.”

Even the retraction note is reasonably forthcoming: Continue reading Now this is transparent: Retraction for plagiarism earns 4-page editor’s note

Concerns attached to three more papers by retraction-laden management researcher

Fred Walumbwa
Fred Walumbwa

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:

Poop paper flushed due to possible sample contamination

cover (3)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.

Sample tampering leads to plant scientist’s 7th retraction

Jorge Vivanco
Jorge Vivanco

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.

In other words, Perry told us:   Continue reading Sample tampering leads to plant scientist’s 7th retraction

“We are living in hell:” Authors retract 2nd paper due to missing raw data

ijcA 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 prof adds his 33rd retraction

James Hunton
James Hunton

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.

After the Bentley University investigation, the journal Contemporary Accounting Research conducted its own review of the paper, and found “no credible evidence exists to support the validity of the data in the study,” according to the retraction note for “Decision Aid Reliance: A Longitudinal Field Study Involving Professional Buy-Side Financial Analysts.”

Here’s the entire retraction note:

Author in 2014 peer review ring loses 3 more papers for peer review problems

cover (1)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.

The retraction notes for all three papers — published in Human Factors and Ergonomics in Manufacturing & Service Industries — are identical:

Peer reviewer steals text for his own chemistry paper, gets sanctioned by journal

Screen Shot 2016-02-06 at 6.46.54 PM

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.”

The retraction note for the 2015 paper, “Controllable Electrochemical Synthesis of Silver Nanoparticles on Indium-Tin-Oxide-Coated Glass” explains how the editors at ChemElectroChem became aware of the plagiarism:
