13th retraction issued for Jesús Ángel Lemus

Proceedings of the Royal Society B- Biological SciencesA 13th retraction has been published for Jesús Ángel Lemus, the Spanish veterinary researcher whose work colleagues have had trouble verifying.

This paper was pulled for similar reasons as his other retractions: After retrying the experiments in two independent labs, fellow authors were “unable to arrive to any sound conclusion about the validity of his analyses.” 

Proceedings of the Royal Society B: Biological Sciences posted the notice September 16, three years after the paper received an expression of concern.

The retraction notice, signed by every co-author but Lemus, reads:

Authors “did not have permission” to use pesticide data

10661An environmental journal is retracting an article about the risks of pesticides to groundwater after determining it contained data that “the authors did not have permission (implicit or explicit) to publish.”

According to the retraction note in Environmental Monitoring and Assessment, the paper said the data came from a non-author’s PhD thesis, but it’s not there. Those mysterious data were used to validate a model for pesticide exposures, described in an excerpt from the abstract:  Continue reading Authors “did not have permission” to use pesticide data

Cochrane withdraws review on zinc for colds for data concerns

Cochrane_LogoThe Cochrane Library has withdrawn a 2013 systematic review on zinc’s ability to fight the common cold.

Cochrane often marks reviews “withdrawn” once new evidence emerges that renders them out of date — but in this case, the review was flagged while the editors investigate issues “regarding the calculation and analysis of data.”

Here’s the notice.

Investigation ends in 6th retraction for Voinnet

PLOS PathogensA sixth paper co-authored by plant researcher Olivier Voinnet has been retracted by PLOS Pathogens “following an investigation into concerns.”

The investigation found “several band duplications” in one figure provided by fifth author, Patrice Dunoyer, who took it from “the Master thesis of a former student working under his supervision, without the prior consultation or consent of this student,” according to the notice. There was also an incorrect “loading control” in another figure, attributed to first author Raphael Sansregret and last author Kamal Bouarab. 

Voinnet and Bouarab, the study’s corresponding authors, took full responsibility for “the publication of this erroneous paper.”

Although investigators found that the raw data in the duplicated figure backed up its conclusions, “given the nature and extent of data manipulation,” the authors asked the journal to retract the paper .

Investigation finds “careless data workup” in alcoholism drug paper

S00142999

An investigation at Karolinska Institute has led to the retraction of a paper about drug treatments for alcoholics, after concluding the article contains a “very careless data workup.”

The paper, “Memantine enhances the inhibitory effects of naltrexone on ethanol consumption,” found that the drug memantine (normally used to treat Alzheimer’s) enhances the effects of naltrexone in rats, which blocks the high of alcohol.  It was published in the European Journal of Pharmacology and has been cited 10 times, according to Thomson Scientific’s Web of Knowledge.

However, its conclusion is now “unreliable,” according to the retraction note:

Marine mammal injury study retracted for using restricted gov’t data

Integrative ZoologyA 2012 paper that analyzed injuries to aquatic mammals in China has been retracted “due to the usage of restricted data from the Ministry of Agriculture of China.”

The authors — from Shandong University in China, The University of Hong Kong and the Peruvian Centre for Cetacean Research — “organized the collection of official documents related to strandings, bycatches and injuries of aquatic mammals in the waters of mainland China from provincial fishery administrations for the years 2000 to 2006,” according to the abstract. However, they may not have been supposed to do that.

Here’s the retraction notice from Integrative Zoology (which is paywalled, tsk, tsk):

Journal corrects CrossFit injury data in paper at center of lawsuit

XLargeThumb.00124278-201509000-00000.CVA study on the trendy and grueling workout regimen known as CrossFit has a correction concerning the number of participants hurt during 10 weeks of training. The paper has been the center of multiple lawsuits  — one by CrossFit, and one by a CrossFit gym owner — for allegedly over-inflating the risks associated with the regimen.

The original paper claimed that 9 of 54 participants dropped out of the study due to “overuse or injury.” The correction note says that just two left for those reasons.

The paper, published in The Journal of Strength and Conditioning Research actually concludes that CrossFit has some benefits. According to the abstract: Continue reading Journal corrects CrossFit injury data in paper at center of lawsuit

Lizards aren’t getting hotter faster than the planet after all, says retraction

EcographyA paper that raised alarms by suggesting lizards were warming even faster than the planet has been retracted after the authors employed the wrong method to measure temperatures.

Some scientists thought that, because of the way lizards retain heat to regulate their cold-blooded bodies, they might be more sensitive to temperature changes. Well, not in this case. The paper has been retracted from Ecography because the scientists erred in calculating the “radiative conductance of the animal” — basically, how much heat it can get rid of — such that the “broad-scale” conclusions of the study are invalid.

The notice for the aptly named paper “Lizards could be warming faster than climate” reads: Continue reading Lizards aren’t getting hotter faster than the planet after all, says retraction

Divorce study felled by a coding error gets a second chance

home_cover (1)A journal has published a corrected version of a widely reported study linking severe illness and divorce rates after it was retracted in July due to a small coding error.

The original, headline-spawning conclusion was that the risk of divorce in a heterosexual marriage increases when the wife falls ill, but not the husband. The revised results — published again in the Journal of Health and Social Behavior, along with lengthy explanations from the authors and editors — are more nuanced: Gender only significantly correlates with divorce rate in the case of heart disease.

The authors’ note, from Iowa State’s Amelia Karraker and Kenzie Latham, at Indiana University-Purdue University Indianapolis, explains that the coding error led them to over-estimate how many marriages ended in divorce:

Former accounting prof adds his 32nd retraction

James Hunton

Another retraction makes 32.5 for former accounting professor James E. Hunton, and earns him the #10 slot on our leaderboard.

Though he resigned from his position at Bentley University in 2012, the story didn’t end there: In 2014, a university investigation found he’d committed misconduct in two papers. The, in June 2015, he notched 25 retractions all at once.

The newly retracted paper, “Effects of Anonymous Whistle- Blowing and Perceived Reputation Threats on Investigations of Whistle-Blowing Allegations by Audit Committee Members,” published in the Journal of Management Studies, suggests that, for public corporations, an anonymous whistleblower might not be as effective as an alert from a known source. The publisher Wiley put out a press release for the paper in 2010, and it succeeded in garnering some coverage.

Whether its conclusion remains valid is unclear, as Hunton didn’t provide evidence to support the validity of the data. The note explains:
