Author: Journal’s unapproved edits distorted my ideas

Researcher Floribert Patrick Endong had been looking forward to seeing his paper in print. Several months after he submitted it to Gender Studies, the journal told him in March that it was online. But when he read it, Endong was disappointed to see some changes he had not approved, which he believed “deformed much of the initial text.”

It turns out, the journal “did not allow me to vet the changes before publication,” he explained. Continue reading Author: Journal’s unapproved edits distorted my ideas

When — and how — should journals flag papers that don’t quite meet retraction criteria?

Readers of Retraction Watch will be no strangers to the practice of issuing Expressions of Concern — editorial notices from journals that indicate a paper’s results may not be valid. While a good idea in theory — so readers can be aware of potential issues while an investigation is underway — in practice, it’s a somewhat flawed system. As we (and others before us) have shown, so-called EOCs can linger indefinitely, leaving researchers unsure how to interpret a flagged paper.

The Committee on Publication Ethics (COPE) agrees that the system has room for improvement. Although COPE has included advice on when to issue EOCs within its retraction guidelines, it has allotted time in the next COPE Forum (Feb 26) to discuss the topic. Some questions it’s considering:

“Major advance” in solar power retracted for reproducibility issues

The authors of a highly cited 2016 research letter on a way to improve the efficiency of solar panels have retracted their work following “concerns about the reproducibility.”

Given the potential importance of the data, it would be nice to know what exactly went wrong, and why. However, the retraction notice doesn’t provide many details, and doesn’t even specify if the authors did indeed fail to reproduce the data.

The letter, titled “Graded bandgap perovskite solar cells,” was published in Nature Materials by a group out of the University of California at Berkeley and the affiliated Lawrence Berkeley National Laboratory. The 2016 article has been cited 16 times, according to Clarivate Analytics’ Web of Science, earning it the ranking of “highly cited.”

Berkeley heralded the findings in a press release as a “major advance” in the field of solar energy:

Should a journal retract a paper the authors didn’t know contained bad data?

A medical journal has retracted a 2016 paper over a series of errors, prompting it to lose faith in the paper overall. The authors have objected to the decision, arguing the errors weren’t their fault and could be revised with a correction — rather than retracting what they consider “an important contribution” to an ongoing debate in medicine.

The paper explored the so-called weekend effect—that patients admitted to the emergency department on the weekend are more likely to die than those admitted on a weekday. Whether the weekend effect is real is not clear. Some studies have supported the phenomenon in certain areas of medicine, but others (including the now-retracted paper) have failed to find an effect.

First author Mohammed A. Mohammed, based at the University of Bradford in the UK, told Retraction Watch that the errors were introduced by one of the hospitals that provided them the data:

“The sampling had been compromised:” MD Anderson researchers retract cancer study

Erich Sturgis

Researchers from the University of Texas, MD Anderson Cancer Center have retracted a 2015 paper after they discovered their samples had been compromised.

Exactly how the samples were compromised, and how and when the researchers found out, remains unclear.

Originally published March 30, 2015, in Cancer, “Genome-wide association study identifies common genetic variants associated with salivary gland carcinoma and its subtypes” reported that at least three protein-coding gene variants were associated with rare salivary gland cancers. In the paper, the authors — all but one of whom are affiliated with MD Anderson — cautioned that they still needed to confirm the findings and figure out the mechanism by which the genes might increase the risk of cancer.

On Oct. 23, 2017, the researchers asked the journal to either correct or withdraw the paper. According to the retraction notice issued Jan. 9, the researchers had discovered: Continue reading “The sampling had been compromised:” MD Anderson researchers retract cancer study

Unusual: Author uses a reference list to accuse a paper of plagiarism

Here’s an unusual way to allege plagiarism: Do it in the reference list.

That’s what Brian Levine, a professor in the College of Information and Computer Sciences at the University of Massachusetts in Amherst, did when he came across a paper he wanted to cite but suspected of plagiarism. When Levine published his 2017 paper, he cited the paper in question as:  

R.Rajan, “ Feasibility, Effectiveness, Performance and Potential Solutions on Distributed Content Sharing System [plagiarized],” Intl. J. Engineering and Computer Science, 5(1):15638–15649, Jan 2016 http://www.ijecs.in/ issue/v5- i1/30%20ijecs.pdf.

Levine’s paper, which explores a way of identifying perpetrators of online child pornography, provides no further details about the nature of the plagiarism or from what source the paper allegedly plagiarized. Continue reading Unusual: Author uses a reference list to accuse a paper of plagiarism

Three papers retracted… for being cited too frequently

An engineering journal has retracted three 2016 papers. The reason: They had been cited too often.

Although the reason for the retractions may sound odd, the editor, Minvydas Ragulskis, told Retraction Watch he was concerned an author had engaged in citation manipulation. Specifically, Ragulskis explained that the majority of the citations came from papers at a 2017 conference on which one of the authors, Magd Abdel Wahab, was chair—raising suspicion that he had asked conference presenters to cite his work.

Almost three-quarters of papers that cited Wahab’s work originated from the conference, which “is large enough to assume a high probability for citation manipulation,” Ragulskis said. (Wahab, Professor and Chair of Applied Mechanics at Ghent University in Belgium, was not a co-author on the conference papers that cited his work.)

Study that said hate cuts 12 years off gay lives fails to replicate

A highly cited paper has received a major correction as a result of the ongoing battle over attitudes towards gay people, when a prominent — and polarizing — critic showed it could not be replicated.  

In December 2017, researchers led by Mark Hatzenbuehler of Columbia University corrected the paper, originally published in Social Science & Medicine in February 2014, which showed that gay people who live in areas where people were highly prejudiced against them had a significantly shorter life expectancy. The corrigendum came more than a year after a researcher who has testified against same-sex marriage was unable to replicate the original study.

“Structural stigma and all-cause mortality in sexual minority populations,” has been cited 102 times, according to Clarivate Analytics’ Web of Science, and attracted media coverage when it was published, from outlets such as Reuters and U.S. News & World Report.

Caught Our Notice: Swiss group loses 4th paper for data manipulation

Title: Dysferlin Interacts with Histone Deacetylase 6 and Increases alpha-Tubulin Acetylation

What Caught Our Attention:  After losing three articles for data manipulation, Michael Sinnreich has retracted another paper in PLoS ONE.  All four retractions share some of the same authors, including Bilal Azakir and Sabrina Di Fulvio, who is listed as the first author on the latest retraction. None of the notices have identified a person responsible for the data manipulation. Three years ago, PubPeer user had flagged some of the figures mentioned in the notice — noting that he was “led to this paper by a story on Retraction Watch” — most likely, a 2014 post that flagged an ongoing discussion about one of Sinnreich’s papers on PubPeer.

Macchiarini, 3 co-authors found guilty of misconduct in 2015 paper

The Karolinska Institutet in Sweden has declared that once-lauded surgeon Paolo Macchiarini and three co-authors committed misconduct in a 2015 paper.

The decision by KI’s vice chancellor will be followed by a request to retract the paper, published by the journal Respiration.

In the paper, the researchers described the case of a man with an acute lung disorder, in which he received an experimental treatment involving the use of his own blood-derived cells and the drug erythropoietin, which stimulates the production of red blood cells. The patient “demonstrated an immediate, albeit temporary, clinical improvement,” according to the authors. However, he ultimately died of multisystem organ failure.
