More notices appear for embattled Cornell food researcher

Journals have posted two corrections alongside papers by Brian Wansink, a food researcher whose work has lately come under fire.

One of the corrected papers was among the initial batch that raised eyebrows last year; after Wansink praised the productivity of one of his researchers, critics suggested four papers contained critical flaws. The questions about his work soon extended to other papers, one of which was retracted in April. That month, an internal review by Cornell University announced that Wansink made numerous mistakes, but did not commit misconduct. Wansink has pledged to reanalyze multiple papers.

One paper that was among those initially criticized has received a formal correction notice from the Journal of Product & Brand Management. The notice, which appears behind a paywall, has drawn fire from a regular critic of Wansink’s work, Jordan Anaya, who argues “this correction actually needs a correction, actually several.”

Here’s the notice for “Peak-end pizza: prices delay evaluations of quality:”

Are there foxes in Tasmania? Follow the poop

Stephen Sarre, based at the University of Canberra in Australia, has made a career out of collecting and analyzing poop.

It’s a tough job, but someone’s got to do it. Part of his work is designed to answer a multi-million dollar question: Is Tasmania home to foxes, a pest that carries rabies and other diseases and can ravage local wildlife? According to the Australian news outlet ABCthe Tasmanian and Australian governments have spent $50 million (AUD) on hunting foxes on the island since 2001 — even though many have debated whether they are even there.

In 2012, after analyzing thousands of fecal samples, Sarre published a paper in the Journal of Applied Ecology which boldly claimed that “Foxes are now widespread in Tasmania.” But many outside researchers didn’t buy it, and quickly voiced their criticisms of the paper, namely that there may be problems with false positives and the methodology used to analyze the samples. Recently, the journal issued an expression of concern for the paper, citing an ongoing investigation into the allegations.

Here’s the expression of concern (paywalled, tsk tsk):

The retraction countdown: How quickly do journals pull papers?

After Tina Wenz was found guilty of scientific misconduct, how long did it take for journals to retract the problematic papers?  The answer: Between three and nine months.

In September 2016, the University of Cologne found that Wenz had committed scientific misconduct in six papers and requested they all be retracted. From that point on, the retraction clock was ticking.

We’ve explored how long it takes a journal to act over the years, and we’ve found that the time between identifying a problem to retracting the paper can vary — and sometimes last years.

In Wenz’s case, one of the papers—published in Cell Metabolism in 2009—had already been retracted in 2015. Three of the remaining five were retracted in December 2016—a 2008 paper in Cell Metabolism, a 2009 paper in Proceedings of the National Academy of Sciences (PNAS), and a 2009 paper in the Journal of Applied Physiology.

In January 2017, the journal IUBMB Life pulled a 2014 paper flagged in the investigation. And just over nine months after Wenz was found guilty of misconduct, the last paper—published in 2013 in Mitochondrion—has been retracted.

The most recent notice states that the University of Cologne requested the retractions, after determining that the data had been “inappropriately manipulated.”

Here’s the retraction notice in Mitochondrion:

Inclusion of “personal correspondence” in evolution paper prompts retraction, new journal policy

Hearsay is not admissible as evidence in court — and it doesn’t seem to go very far in science, either.

A pair of researchers in the field of human evolution have lost a paper which contained data from “personal correspondence” that the providing party apparently did not enjoy seeing in print.

The article, “Early hominin biogeography in Island Southeast Asia,” was published in the September/October 2015 issue of Evolutionary Anthropology. The authors, Roy Larick and Russell Ciochon, are paleoanthropologists and co-founders of the Iowa-Bandung Java Project — a 20-year old collaborative effort to study the origins of early humans in Indonesia.

Plagiarism costs author five papers in five different journals

An engineering researcher has written about models tackling a range of complex issues — security problems in Iraq, poverty in Europe, and emergency responses to humanitarian crises. But there may be some limits to his expertise: Between 2016 and 2017, five journals have retracted five of his papers, citing plagiarism.

Some of the notices describe the plagiarism as “extensive,” “significant,” and “substantial.” One journal editor, who retracted one of Kubilay Kaptan’s papers last year, told us the paper “was simply a direct copy from an existing one.”

The editor noted that Kaptan — who lists his affiliation as the Civil Engineering Department at Beykent University in Istanbul — claimed to be “the victim of a personal smear campaign, which involved submitting plagiarised manuscripts in his name.” We reached out to Kaptan several times by phone and email to verify this claim, but did not hear back.

Here’s the most recent retraction, for a 2016 paper published in Journal of Refugee Studies  Continue reading Plagiarism costs author five papers in five different journals

12 years after researcher found guilty of misconduct, journal retracts paper

In 2005, the U.S. Office of Research Integrity found an obesity researcher had engaged in scientific misconduct.

More specifically, the ORI report revealed that Eric Poehlman, then based at the University of Vermont, had “falsified and fabricated” data in 10 papers. The 2005 report asked that the journals issue retractions or corrections to the papers. By 2006, six of those papers were retracted (1, 2, 3, 4, 5, 6). In 2006, a judge sentenced Poehlman to one year and one day in prison for falsifying research data.

In 2015, we explored how long it takes a journal to retract a paper. We found that four of the 10 papers had still not been retracted — one appeared to be missing from Medline, another had received a correction (as the ORI report requested), and two had not been retracted or corrected (1, 2).

Until now. Continue reading 12 years after researcher found guilty of misconduct, journal retracts paper

Journal hit by citation scandal named among top in field

It’s been a mixed year for Wiley’s Land Degradation & Development.

Following accusations of citation irregularities at the journal (whose its Impact Factor rose dramatically from 3.089 in 2014 to 8.145 in 2015), its editor was asked to resign. Another editor resigned shortly after.

But last week, Clarivate Analytics named the journal among the top 10 in the field of climate change, as part of its annual Journal Citation Reports.

The annual report also lists a number of journals that have been suppressed from Clarivate’s analysis “due to anomalous citation patterns;” Land Degradation & Development is not listed among the 13 journals this year.

A spokesperson for Clarivate told us:

A retraction gets retracted — but the first author’s contract is still terminated

After issuing a retraction notice May 30 for a biomedical engineering paper, the journal has since pulled the notice, citing “a potential problem.”

After doing some digging, we’ve learned more about the “potential problem.”

Apparently, the retraction was requested by Nanyang Technological University (NTU) in Singapore. NTU has been investigating the first author for months, after it received an allegation about an unrelated manuscript. As a result, NTU terminated first author Hamidreza Namazi‘s contract as a research fellow earlier this year.

As part of the investigation, NTU began to look at Namazi’s other papers, and discovered several with potential problems — including this one, which NTU believes did not receive proper ethical approvals. So it contacted the journal to raise its concerns.

Namazi, however, told us that he and his colleague obtained approval from another organization, but didn’t make that clear in the paper — so the journal has retracted its retraction notice while it investigates Namazi’s claim.

In place of the original retraction notice, a notice now reads:

Authors retract two plant biology papers over duplicated images

Plant scientists have issued two retractions after noticing several images had been duplicated within and across the papers.

The papers both appeared in March 2002 in The Plant Cell and The Plant Journal.

The last author on both papers — Jonathan Jones, a professor and group leader at The Sainsbury Laboratory in Norwich, UK — took responsibility for the duplications. He told us:

As last author I was responsible for checking the papers but did not notice the similarities between figures in the different papers.  I regret this and took action as soon as I realized there was an issue. Both papers went through peer review and the issue was not picked up at that point either.

Susana Rivas, the first author on both papers, has collaborated with beleaguered plant scientist Oliver Voinnet — and was a second author on one of his eight retractions (which we covered here).

The editor-in-chief of TPJ Christoph Benning said that, after the authors contacted them, the journals looked into the issue, confirmed the duplications and then retracted the papers: Continue reading Authors retract two plant biology papers over duplicated images

Journal retracts Ohio State CrossFit study at center of lawsuits

The fallout continues for a study conducted at a local CrossFit gym by researchers at The Ohio State University. First it was corrected, now it’s been retracted, and it continues to be the basis of litigation against both the authors and the publisher.

Editors at the Journal of Strength and Conditioning Research have decided to pull the 2013 study after learning that the research protocol had not been approved by Ohio State’s institutional review board (IRB).

Over the past few years, the study has spawned several lawsuits, including a defamation suit brought by gym owner Mitch Potterf against Ohio State that landed him a six-figure settlement, as well as an ongoing suit by Potterf against the National Strength and Conditioning Association (NSCA, which publishes the journal). The CrossFit brand has also sued the NSCA. [See update at end of post for more on that case.]

An NSCA statement issued May 30 describes what happened: Continue reading Journal retracts Ohio State CrossFit study at center of lawsuits
