Plant biologist earns string of retractions, bringing total to 9

A pair of plant biologists has lost a string of papers over concerns about image manipulation. One author has added eight new retractions to his CV; the other has added five.

Last summer, a journal retracted another paper by the pair, also citing suspicions of image manipulation. The latest batch of retractions — issued by seven different journals — includes some papers that have been questioned on PubPeer.

Dibyendu Talukdar, listed at the University of Calcutta in West Bengal, India, is the sole author on three retracted papers. He shares five new retractions with Tulika Talukdar listed at the University of North Bengal. That brings their totals to nine and six, respectively. (We’re not sure if the Drs. Talukdar are related).

We’ll start with the papers they share: Continue reading Plant biologist earns string of retractions, bringing total to 9

A new record: Major publisher retracting more than 100 studies from cancer journal over fake peer reviews

Springer is retracting 107 papers from one journal after discovering they had been accepted with fake peer reviews. Yes, 107.

To submit a fake review, someone (often the author of a paper) either makes up an outside expert to review the paper, or suggests a real researcher — and in both cases, provides a fake email address that comes back to someone who will invariably give the paper a glowing review. In this case, Springer, the publisher of Tumor Biology through 2016, told us that an investigation produced “clear evidence” the reviews were submitted under the names of real researchers with faked emails. Some of the authors may have used a third-party editing service, which may have supplied the reviews. The journal is now published by SAGE.

The retractions follow another sweep by the publisher last year, when Tumor Biology retracted 25 papers for compromised review and other issues, mostly authored by researchers based in Iran. With the latest bunch of retractions, the journal has now retracted the most papers of any other journal indexed by Clarivate Analytics’ Web of Science, formerly part of Thomson Reuters. In 2015, its impact factor — 2.9 — ranked it 104th out of 213 oncology journals.

Here’s more from Springer’s official statement, out today:

Fraud by bone researcher takes down two meta-analyses, a clinical trial, and review

The troubles continue for a bone researcher, who’s lost multiple papers in recent months due to problems ranging from data issues to including authors without their consent.

Now, journals have retracted two more papers by Yoshihiro Sato. And in a sign of the downstream effects that fraud can have, another journal has retracted two meta-analyses by other authors that cited his work.

Earlier this month, the journal Current Medical Research and Opinion retracted the two meta-analyses because they were based on recently retracted papers by Sato, affiliated with Mitate Hospital. The two new retractions of Sato’s papers are a review and a randomized controlled trial.

Sato was not an author on the meta-analyses published in 2008 and 2011; he was, however, first and lead author on all the retracted papers referenced in the notices. The notices state that the trio of authors on the meta-analyses:

Author surprised when publisher pulls three of her papers

A researcher is strongly objecting to a publisher’s decision to retract three of her papers from two computing journals without informing her first.

The reason: Self-plagiarism, which the author said stemmed from her PhD student using similar descriptions for the background sections of the papers. She argued that if the reviewers had flagged the duplication, she would have been happy to revise the papers before publication. A representative of the publisher, Springer, told us the overlap was extensive enough for the journal to determine the papers should be retracted.

We spoke with Sameem Abdul Kareem from the Department Of Artificial Intelligence at the University of Malaya in Malaysia, last author on all three papers, which she co-authored with her former PhD student Haitham Badi (also referred to as Haitham Hasan in several papers). She explained how the duplication occurred:

Most citations to retracted papers don’t note they’re problematic, authors say

Gali Halevi

We’ve known for a while that too many researchers cite retracted papers. But in what context do those citations occur? Are some authors citing a retracted paper as an example of problematic findings, or do most citing authors treat the findings as legitimate, failing to realize they are no longer valid? In a new paper in Scientometrics, Gali Halevi at Icahn School of Medicine at Mount Sinai in New York and Judit Bar-Ilan at Bar-Ilan University in Israel examined citations to 15 papers retracted in 2014. Halevi told us why she was surprised to see how many authors don’t realize retracted papers are problematic, and what the publishing community can do to get the word out.

Retraction Watch: We’ve noticed that many papers are cited long after being retracted, without notifying readers the paper is problematic. You looked at citations to retracted papers and tracked how the citing authors described the paper – noting that its findings were problematic given the retraction (negative), or treating the findings as legitimate research that affirms the newer paper’s results (positive). The vast majority of post-retraction citations – 83% — were positive. Did that surprise you?

Neuroscientist Stanley Rapoport hasn’t had much luck with his co-authors.

Recently, we’ve reported on multiple retractions of papers co-authored by Rapoport after three different first authors were found to have committed misconduct. Now, the fallout from one of those cases had led to four more retractions, bringing Rapoport’s total to 12.

The latest batch of retractions stem from the actions of Jagadeesh Rao.

Here’s the first notice, issued by Psychopharmacology:

Faked data, plagiarism, no co-author okays…yeah, this paper’s been retracted

A researcher in South Korea has retracted a 2016 paper on which he is listed as senior author because a former student wrote and published the article without his permission.

According to the retraction notice, the former student also fabricated data and plagiarized “a substantial amount of material” from previous papers published by the senior and middle author.

Here’s the retraction notice for “Oleaginous yeast-based production of microbial oil from volatile fatty acids obtained by anaerobic digestion of red algae (Gelidium amansii),” published in the Korean Journal of Chemical Engineering in April 2016 and retracted in January: Continue reading Faked data, plagiarism, no co-author okays…yeah, this paper’s been retracted

Students withdraw report of private stem cell retreat

Master’s students have retracted a review of an internal meeting of stem cell researchers because it contained confidential information.

According to the Managing Director of the society, Stem Cell Network North Rhine Westphalia (NRW), the event was not open to the public, and the authors had not contacted either the society or the scientists they cited before publishing the report.

Here’s the retraction notice for “A Report on the Internal Retreat Meeting of the Stem Cell Network North Rhine Westphalia,” published online in Molecular Biotechnology on October 31 and retracted shortly after on December 14: Continue reading Students withdraw report of private stem cell retreat

Authors contest retractions for “high degrees of similarity” with previous papers

A group of researchers has lost two papers due to “high degrees of similarity with previously published works,” according to the notices.

The authors are objecting to the retractions, however, arguing the journal never gave them an opportunity to show their work is different from the previous papers.

Both papers were published in the International Journal of Plastics Technology, and share the same three authors, all based at Charan Singh University in India. They were retracted by the Editor in Chief, according to the notices.

Effect of dynamic cross-linking on melt rheological properties of isotactic polypropylene (iPP)/ethylene–propylene diene rubber (EPDM)/nitrile rubber (NBR) elastomeric blends” was published in 2011. Here’s the retraction notice:

How did a book chapter end up with two authors who didn’t contribute to it?

An erratum for a book chapter about water pollution has removed two out of the three original authors. 

What’s more, the notice specifies that “any mistakes or omissions are the sole responsibility” of the remaining author, Michael Yodzis of the University of Guelph in Ontario, Canada. 

This isn’t something we see every day, but one of the removed authors told us he believes the paper is scientifically valid — he just didn’t have anything to do with it. Yodzis told us he included the two authors by mistake, after believing he had corresponded with them about the paper, which was an extension of their previous work together.

Here’s the erratum, issued in December: Continue reading How did a book chapter end up with two authors who didn’t contribute to it?
