We’re not “citation police:” No more errata for omitted citations, says economics journal

An economics journal has corrected a paper for the second time for failing to cite previous studies — and said in a separate note that it no longer plans to publish similar errata, with rare exceptions. 

In September 2015, we reported on the first erratum for “Incentives for Creativity” — a paper that analyzed ways of inspiring creativity in the workplace — after it failed to cite relevant papers. One year on, the same paper has another erratum for a similar reason: not citing relevant papers from another field.

You don’t often see two errata for the same mistake — omitted citations — on one paper. Even less often do you see journal editors co-publishing a note saying they don’t plan on issuing any more such notices. Here’s an excerpt from the editor’s note in Experimental Economics: Continue reading We’re not “citation police:” No more errata for omitted citations, says economics journal

U.S. gov’t scientist says he was banned from climate research at work — so he used a pseudonym

A scientist working for the U.S. government says he was told not to work on climate research during working hours, nor reveal his government affiliation when presenting results. So he published his research under a pseudonym instead.

The researcher explains all this in a recent erratum for one of the papers he published under a different moniker — confirming why he and his co-author used the same pseudonyms to publish another now-withdrawn paper that presented some controversial climate findings. That withdrawal — which we covered in in September (as did the Washington Post) — raised eyebrows after Twitter users began pointing out that the authors — Den Volokin and Lark ReLlez — have similar names to another pair of researchers: Ned Nikolov and Karl Zeller. 

Nikolov’s use of a pseudonym even prompted a misconduct investigation by his employer, the U.S. Department of Agriculture Forest Service.

Here’s the erratum, issued last week for a 2014 paper in SpringerPlus:

Genetics study flagged for reliability issues by Frontiers journal

frontiers-in-geneticsA genetics journal has issued an expression of concern (EOC) for a study after an investigation by its chief editors.

According to the notice in Frontiers in Genetics, the authors of the paper — based at Hokkaido University in Sapporo, Japan — are conducting further experiments to resolve the issues raised by the journal’s investigation.

In February, the same paper received a corrigendum due to errors in the assembly of one of the figures.

Here’s the EOC, issued earlier this week: Continue reading Genetics study flagged for reliability issues by Frontiers journal

Authors retract third cancer paper for missing original data

international-journal-of-oncologyResearchers have retracted their third paper due to missing original data, following an investigation at their former institution in New York.

We’ve previously reported on two retractions of papers co-authored by Bhagavathi Narayanan and Narayanan K. Narayanan, previously based at the New York University (NYU) School of Medicine. The studies were pulled when the pair couldn’t provide original images to investigators at NYU School of Medicine. One author has blamed the lack of original data on the abrupt closure of her previous institution in 2004, after it allegedly misspent millions in federal grants. 

However, the latest retraction affects a paper published eight years later in the International Journal of Oncology. Its coauthors include Bhagavathi Narayanan, Narayanan K. Narayanan and Rajkishen Narayanan; we haven’t been able to uncover if there is a relation between them.

A spokesperson for the NYU School of Medicine sent us this statement: Continue reading Authors retract third cancer paper for missing original data

Leading diabetes researcher acted negligently, probe concludes

Kathrin Maelder
Kathrin Maedler

Several duplications in the work of a prominent diabetes researcher were the result of negligence, but there is not enough evidence to support charges of misconduct, according to an investigation at her university in Germany.

Recently, we’ve reported on several notices for papers co-authored by Kathrin Maedler, a researcher at the University of Bremen. So far, Maedler has one retraction, multiple corrections, and two expressions of concern to her name, after several of her papers were questioned on PubPeer. Previously, the University of Zurich in Switzerland — where Maedler completed her PhD in 2002 — determined there was a lack of evidence to support allegations of misconduct in papers that were part of her doctoral thesis. 

Last week, the University of Bremen released its own investigation report (in German), which we translated using One Hour Translation. It concludes that Maedler Continue reading Leading diabetes researcher acted negligently, probe concludes

Authors fix three Diabetes papers flagged for image issues

diabetesResearchers have corrected three studies published in the journal Diabetes after users flagged issues with the images on PubPeer.

All three papers share a number of authors, including the same last and corresponding author, Aimin Xu, from The University of Hong Kong.

Since the corrections appear relatively extensive, we asked the journal if retractions were ever on the table. According to Chris Kohler, associate publisher, scholarly journals at American Diabetes Association, which publishes Diabetes, an ethical panel reviewed the papers before allowing the authors to issue the errata, all of which were published online this month: Continue reading Authors fix three Diabetes papers flagged for image issues

CrossFit can sue over error in paper it claims cost the brand millions

court-caseA California court ruled that fitness empire CrossFit can proceed to trial with its lawsuit against a competitor, alleging it published falsified data that hurt the company’s reputation, according to recently released court documents.

The case pits the popular for-profit CrossFit brand against the non-profit National Strength and Conditioning Association (NSCA), which published the 2013 study in question.

CrossFit claims it lost upwards of $8 million afer researchers concluded that 16 percent of CrossFit participants in a small study left the exercise program because of injury. However, in a 2015 erratum, the authors – led by Steven T. Devor, director of the Exercise Science Laboratory at The Ohio State University — noted that follow up showed only 2 participants out of the 11 drop-outs mentioned their health as a reason.

The study appeared in the Journal of Strength & Conditioning Research, published by CrossFit competitor NSCA, which also promotes fitness programs.  CrossFit claims the results in the paper cost it revenues from people paying for seminars at CrossFit, Inc. affiliate gyms.

“CrossFit is now eager to go to trial. More eager than ever,” a CrossFit spokesperson told Retraction Watch: Continue reading CrossFit can sue over error in paper it claims cost the brand millions

Spanish lab admits to image manipulation, retracts one paper, corrects another

JBCA group has retracted one paper and corrected another in the Journal of Biological Chemistry (JBC) for image manipulations.

Last author José G. Castaño told us the manipulation occurred at the Universidad Autónoma de Madrid, where he and one other co-author are based. He declined to name who was responsible.

Here’s the retraction notice for “Cytomegalovirus promoter up-regulation is the major cause of increased protein levels of unstable reporter proteins after treatment of living cells with proteasome inhibitors:”

Author lifts from one paper in two different articles. Why does one journal retract, while the other corrects?

circ resAre there instances when similarities between papers should be fixed by a correction, rather than a retraction?

We’re asking ourselves that question after seeing two journals take very different approaches to a somewhat similar situation. Last year, Frontiers in Physiology retracted a paper by Anastasios Lymperopoulos at Nova Southeastern University in Florida because of an “an unacceptable level of similarity” to a 2009 review article by different authors. But more recently, after Circulation Research discovered another paper co-authored by Lymperopoulos also contained similar text from the same 2009 review, it decided to correct the passages.

The last author of the Circulation Research paper told us the overlap between the two papers was less than 5%, and the journal never suggested the authors retract the paper.

Here’s the correction notice in Circulation Research:
