So, was it plagiarism? Journal retracts three papers over “citation and attribution errors”

When several recent submissions raised a red flag, a pediatrics journal decided to investigate. The journal, Pediatrics in Review, discovered “citation and attribution errors” in three case studies, which the journal has now retracted.  

Luann Zanzola, the managing editor of the journal, explained that the editors caught the errors when they scanned the three papers—one published in 2014 and two in 2015—using the plagiarism detection software, iThenticate. Zanzola told us that the three case studies “were flagged for high iThenticate scores,” and when the authors could not adequately explain the amount of text overlap, the editors retracted the papers.

The retraction notices for the three papers, published in the journal’s September 2017 issue, are identical: Continue reading So, was it plagiarism? Journal retracts three papers over “citation and attribution errors”

Journal adds concern notice to paper by psychologist Jens Förster

A social psychology journal has added an expression of concern to a paper by prominent social psychologist Jens Förster, whose work has been subject to much scrutiny.

This is the latest in a long-running saga involving Förster. The 2012 paper in the Journal of Experimental Social Psychology had been flagged by a 2015 report describing an investigation into Förster’s work, which had concluded the paper likely contained unreliable data. Several other papers that received similar designations in that report have either been retracted or received expressions of concern (EoC).

The (paywalled) notice provides a lengthy explanation for why the journal chose to add an EoC, rather than retract the paper, as the University of Amsterdam had recommended. Here is an excerpt:

Miffed at exclusion from a meta-analysis, researcher writes own “expression of concern”

On June 10, Psycho-Oncology, a journal that publishes research on the “psychological, social, behavioral, and ethical” side of cancer, received a complaint.

In a letter, Ad Kaptein, a researcher at the Leiden University Medical Centre, in the Netherlands, wrote to say that a review and meta-analysis published by the journal that month hadn’t adequately cited the relevant literature in the field, including seven studies co-authored by Kaptein himself. The authors of the original paper say they had considered citing Kaptein’s work but decided against it, for various reasons.

The journal considered Kaptein’s complaint valid enough to publish his letter. But the letter carries the title “Expression of concern” — a term usually reserved for editorial notices issued by the journal to warn readers about some aspects of an article. But in this case, the author supplied the term, not the journal — yet the letter is tagged as an Expression of Concern on PubMed, giving the impression the paper has received a formal editorial notice.

Journal Co-Editor Maggie Watson told Retraction Watch:

Controversial Australian journalist’s paper flagged by journal

The Journal of Biological Chemistry has added an expression of concern to a 2003 paper that arose from the PhD thesis of a once-prominent — and controversial — science journalist in Australia.

The first author of the paper is Maryanne Demasi, a journalist whose reporting created unintentional headlines in recent years. In 2013, she produced a controversial series about cholesterol and fat (and even cast doubt on cholesterol-lowering drugs known as statins); in 2016, she was fired from the science program Catalyst, after it aired an episode alleging wi-fi could cause brain tumors.

Now, it appears the research community is taking a second look at some of the work underlying her PhD in rheumatology from Royal Adelaide Hospital. Here’s the notice from the journal:

Prominent food researcher retracts paper from JAMA journal, replaces it with multiple fixes

Brian Wansink

Earlier this week, we reported that high-profile food researcher Brian Wansink — who’s faced months of criticisms about his research — had issued his second retraction. On Thursday, he issued his third.

The retracted paper — a 2012 research letter in the Archives of Pediatrics and Adolescent Medicine, now JAMA Pediatrics — reported that children were more likely to choose an apple over a cookie if the apple included an Elmo sticker. The same day the paper was retracted, Wansink and his co-authors published a replacement version that includes multiple changes, including to the methodology and the results.

The retraction notice lists the mistakes, which the authors say they made “inadvertently:”

Reader complaints prompt retraction of meta-analysis of heart-failure drug

A cardiology journal has retracted a 2016 meta-analysis after the editors had an, ahem, change of heart about the rigor of the study.

The article, “Ivabradine as adjuvant treatment for chronic heart failure,” was published in the International Journal of Cardiology, an Elsevier title.

The authors, a group at the Federal University of São Paulo, Brazil, concluded that: Continue reading Reader complaints prompt retraction of meta-analysis of heart-failure drug

Surgery journal retracts two papers it didn’t mean to publish

The Annals of Surgery has retracted two papers it never intended to publish.

According to journal’s editor, Keith Lillemoe, the papers—published in 2015, two months apart—had undergone full peer review and were rejected, “like 90% of submissions to our journal:”

The decision was clear and the authors were notified.

But somehow, Lillemoe said, “our publishing team mistakenly published the papers and placed them into [e-pub] status totally unbeknownst to the editorial team.”

The authors of one paper told us they were unhappy with how the journal handled the situation.

Lillemoe noted:

Journal republishes withdrawn paper on emergency care prices, amid controversy

The Annals of Emergency Medicine has republished a controversial paper it withdrew earlier this year which compared the cost of emergency care at different types of facilities.

Because the paper drew heavy criticism when it was originally released, the journal has published a revised version, along with several editorials and discussions between the authors and critics. One point of contention: The analysis stems from data provided by an insurance company — Blue Cross Blue Shield — which it declined to share.

The paper — originally published in February —  caught national attention (and raised concerns among some emergency care providers) when it reported the cost of treatment in emergency departments can be significantly higher than at urgent care centers, even for the same conditions. The journal withdrew the paper in spring, and re-published it Tuesday, with minor changes.

First author Vivian Ho at Rice University told us she made “slight changes”  to some headings, phrases, and the appendix, but:

Another retraction hits high-profile food researcher under fire

Brian Wansink

It’s been a rough year for Brian Wansink.

Last year, the prominent food researcher posted a blog praising a student for her productivity in his lab. But when Wansink described his methods, readers became concerned that the lab was using improper research techniques to generate more publications. Earlier this year, researchers posted an analysis of four papers by Wansink about pizza consumption to PeerJ, saying they discovered more than 150 inconsistencies in the data. Now, one of those four papers has been retracted.

On Friday, BMC Nutrition posted a brief notice about the 2015 paper, which examined whether people who pay different amounts for all-you-can-eat Italian buffets feel more or less guilty about how much they ate. The notice says the retraction stems from concerns about the data analysis, and the authors do not agree with the journal’s decision.

The new retraction is the second for Wansink, director of the Food and Brand Lab at Cornell.

Here’s the complete retraction notice:

Two more retractions for former US prof who altered dozens of images

Two journals have retracted papers by a biologist who was recently found guilty of misconduct by his former employer, the University of Colorado Denver, bringing the total to five.

The investigation report by UC Denver, which we obtained earlier this year via a public records request, had recommended one of the two newest retractions, which appears in the journal Hepatology. The other retraction, in the Journal of Immunology, was not flagged by the report — which found, among other conclusions, that Almut Grenz had altered multiple values in research that had already been submitted for peer review.

Here’s the notice for the Journal of Immunology paper:
