The fifth of six expected retractions for copyright infringement has arrived for a group of sex researchers led by Willibrord Weijmar Schultz, this one in the International Journal of Gynecological Cancer of a 1992 article.

As we reported earlier this year, Schultz (whose 1999 paper on sex in an MRI won an Ig Nobel prize) and his colleague,  Mels F. Van Driel, were found not to have committed plagiarism by investigators at the University of Groningen. Instead, they were found guilty of “unintended and unknowing breach of copyright.”

But they were asked to apologize formally to a litany of people — from the editors involved to the sponsors of the research — for what the institution described as “unintended and unknowing breach of copyright” of the work of one Diana Jeffrey, whose 1985 dissertation evidently was very much worth reading.

Here’s the latest retraction notice: Continue reading One more paper down for sex researcher Weijmar Schultz

Are US behavioral science researchers more likely to exaggerate their results?

When Retraction Watch readers think of problematic psychology research, their minds might naturally turn to Diederik Stapel, who now has 54 retractions under his belt. Dirk Smeesters might also tickle the neurons.

But a look at our psychology category shows that psychology retractions are an international phenomenon. (Remember Marc Hauser?) And a new paper in the Proceedings of the National Academy of Sciences (PNAS) suggests that it’s behavioral science researchers in the U.S. who are more likely to exaggerate or cherry-pick their findings.

For the new paper, Daniele Fanelli — whose 2009 paper in PLoS ONE contains some of the best data on the prevalence of misconduct — teamed up with John Ioannidis, well known for his work on “why most published research findings are false.” They looked at Continue reading Are US behavioral science researchers more likely to exaggerate their results?

When 1 equals 2, the result is a retraction

bmcrnA group of psychiatric researchers in Norway has lost their 2013 paper in BMC Research Notes on the effects of antipsychotic medications on the brain after discovering that they’d botched their imaging analyses.

The article, “Does changing from a first generation antipsychotic (perphenazin) to a second generation antipsychotic (risperidone) alter brain activation and motor activity? A case report,” came from a trio of scientists at the University of Bergen and Haukeland University Hospital, also in Bergen. According to the abstract of the paper, which was published last May:

Dental journal gives plenty to chew on in retraction of resin paper

jprostoThe Journal of Prosthodontics has retracted a 2006 paper by a pair of Saudi researchers and given them a pass because of an alleged lack of grasp of English — and, we’d add, publishing ethics.

The article, titled “Effect of Chemical Disinfectants and Repair Materials on the Transverse Strength of Repaired Heat-Polymerized Acrylic Resin,” was written by Ayman Ellakwa and Ali El-Sheikh, from institutions in Dammam, Saudi Arabia.

The paper’s abstract stated:  Continue reading Dental journal gives plenty to chew on in retraction of resin paper

Paper on “better-than-average effect” retracted for being, well, worse than average

pers soc psych bullPerhaps what Garrison Keillor says about people is also true of scientific papers:

Welcome to Lake Wobegon, where all the women are strong, all the men are good-looking, and all the children are above average.

There’s been another retraction in social psychology, but before you lump it together with the field’s problem children — read: Diederik Stapel — it seems to be an example of researchers coming forward about an honest error.

Here’s the notice for “The Motivated Self: Self-Affirmation and the Better-Than-Average Effect,” originally published last year in Personality and Social Psychology Bulletin: Continue reading Paper on “better-than-average effect” retracted for being, well, worse than average

Camomile allergy case report retracted after patients withdraw consent post-publication

aaciIn what may be a first, a researcher in Turkey has withdrawn a paper because the patients whose cases she described wthdrew their consent after it was published.

Here’s the notice, from Allergy, Asthma, & Clinical Immunology, of a paper titled “Severe contact dermatitis due to camomile: a common complementary remedy with potential sensitization risks:” Continue reading Camomile allergy case report retracted after patients withdraw consent post-publication

A real shame: Psychology paper retracted when data behind problematic findings disappear

sjdmThe corresponding author of a paper on whether “a sense of shame heightens the desire for money” has retracted it, he claims, after being unable to repeat his analysis to try to fix an issue in the study.

Here’s the notice for “Shame for money: Shame enhances the incentive value of economic resources,” which appeared in Judgment and Decision Making: Continue reading A real shame: Psychology paper retracted when data behind problematic findings disappear

The brains in Spain fall mainly on…Iran?

braininjWe’ve come across some odd examples of plagiarism in this job, from the fellow who tried to build a CV on the back of another researcher’s work, to the education researcher who, from what we can tell, preferred lifting the work of others to writing her own papers. Here’s another odd one for the pile.

A group of Iranian scholars has lost a paper in Brain Injury because they lifted it wholesale from a previously published article. What’s harder to get one’s mind around, however, is that the two papers were looking at culturally-specific aspects of brain injury. Except that one wasn’t.

The retracted paper, “Frontal acquired brain injury, substance abuse and their common psychological symptoms in the Iranian population,” appeared in 2011. Here’s the abstract, which is still available on the journal’s website (we’ll note that although the abstract is free for all, the retraction notice was behind a pay wall — an error, according to the publisher, which they remedied when we contacted them):  Continue reading The brains in Spain fall mainly on…Iran?

Thorax retracts cystic fibrosis paper with bogus data

thoraxA group of European researchers is retracting their 2012 paper in Thorax on the link between cystic fibrosis and the common cold after discovering that the first author, a promising young microbiologist in Switzerland, had made up her data.

The article, titled “Impaired type I and type III interferon induction and rhinovirus control in human cystic fibrosis airway epithelial cells,” purported to describe:

a novel mechanism to explain the increased susceptibility of patients with CF to rhinovirus infections. A profound impairment of the antiviral early innate response in CF airway epithelial cells was identified, suggesting a potential use of IFNs in the treatment of rhinovirus-induced CF exacerbations.

The lead author was Marjolaine Vareille, who at the time was at the University of Bern. Vareille won a L’Oréal France grant in 2007 from the Fondation L’Oréal – Unesco-French Academy of Sciences. The paper has been cited eight times, according to Thomson Scientific’s Web of Knowledge.

But according to the retraction notice: Continue reading Thorax retracts cystic fibrosis paper with bogus data

Dubious stem cell researcher Moriguchi notches temporary withdrawal, notice of redundant publication

bmj case reportsHisashi Moriguchi, who retracted two papers last year because he and his colleagues could not “guarantee the accuracy of the results and conclusions,” has now had another paper withdrawn — at least temporarily.

A notice on the paper, “Autologous human cardiac stem cells transplantation for the treatment of ischaemic cardiomyopathy: first study of human-induced pluripotent stem (iPS) cell-derived cardiomyocytes transplantation,” which appeared in BMJ Case Reports, now reads: Continue reading Dubious stem cell researcher Moriguchi notches temporary withdrawal, notice of redundant publication
