Retraction-plagued management researcher hit with expression of concern

OrgBehav_ak13The editor-in-chief of Organizational Behavior and Human Decision Processes has issued an Expression of Concern about a 2011 paper that explores the link between ethical leadership and employee performance.

The paper, “Linking ethical leadership to employee performance: The roles of leader–member exchange, self-efficacy, and organizational identification,” is one of seven that were flagged in a report by Arizona State University (ASU) that investigated the corresponding author, Frederick Walumbwa, for possible research misconduct, as we noted in November.

“The fit statistics reported in the article contain many errors,” the notice says. It goes on to say that “it is difficult to understand the implications of these errors unless the raw data is made available” — but that the authors were not able to provide it. Here’s the full text of the expression of concern: Continue reading Retraction-plagued management researcher hit with expression of concern

Harvard biofilm paper in Cell breaks down after challenged findings can’t be repeated

CELL_161_4.inddResearchers at Harvard have retracted a Cell paper on biofilm disassembly after they repeated the experiment—following contradictory results from another team—and the new results “can no longer support” the original conclusions.

The 2012 paper, “A Self-Produced Trigger for Biofilm Disassembly that Targets Exopolysaccharide,” describes a factor called norspermidine, produced by the bacteria Bacillus subtilis, that appeared to break down biofilms. The researchers used it to prevent biofilm formation of B. subtilis, Escherichia coli, and Staphylococcus aureus. The paper was cited 72 times, according to Thomson Scientific’s Web of Knowledge.

Two years after it was published, a team from University of Texas Southwestern Medical Center in Dallas and the University of Dundee in the UK contradicted the findings in another Cell publication, “Norspermidine Is Not a Self-Produced Trigger for Biofilm Disassembly.” This time, the authors concluded that norspermidine is not present in B. subtilis biofilms, and actually promotes, rather than breaks down, biofilms. They wrote: Continue reading Harvard biofilm paper in Cell breaks down after challenged findings can’t be repeated

Déjà vu: JBC epigenetics paper is retracted, then largely re-published with fewer authors

JBCA group of authors have withdrawn a 2011 Journal of Biological Chemistry paper, but then appear to have re-published almost the same paper a month later, only this time with just five of the original nine authors.

The paper, “HDAC3-dependent reversible lysine acetylation of cardiac myosin heavy chain isoforms modulates their enzymatic and motor activity,” concerns a type of protein regulation important to cardiac stress. Written by researchers at the University of Chicago and the University of Pittsburgh, it has been cited 16 times, according to Thomson Scientific’s Web of Knowledge. It was rated “Exceptional” by a reviewer on the Faculty of 1000 website.

As we’ve come to expect from the JBC, here’s the full retraction notice, in all its inexplicit glory: Continue reading Déjà vu: JBC epigenetics paper is retracted, then largely re-published with fewer authors

Third retraction for GWU biologist as university seeks to dismiss his $8 million lawsuit

Cancer biologist Rakesh Kumar has chalked up another retraction, this time for “identical,” “duplicated,” and “replicated” figures and images.

It comes on the heels of a flurry of motions in Kumar’s $8 million lawsuit against his employer, George Washington University, for breach of contract and emotional distress because it removed him as department chair last year and placed his research on hold. Kumar remains employed by the university.

The retracted paper, published in Development in 2004, “Metastasis-associated protein 1 deregulation causes inappropriate mammary gland development and tumorigenesis,” analyzed the role of a protein, MTA1, in mammary gland development and cancer. It was published while Kumar was at M.D. Anderson in Houston, and has been cited 81 times, according to Thomson Scientific’s Web of Knowledge.

By our count, Kumar now has three retractions and five corrections. Numerous anonymous comments on Kumar’s papers have been posted on PubPeer, many of them critiquing images. Here’s the complete notice from Development: Continue reading Third retraction for GWU biologist as university seeks to dismiss his $8 million lawsuit

Dude, whose gene is that? Genetics paper retracted for lack of permission

pbrPlant Biotechnology Reports is retracting a 2009 paper by a group of researchers in South Korea because the authors submitted the article “without the permission” of the owner of a gene used in the study.

The paper abstract is no longer online, though the Committee on Publication Ethics (COPE) recommends that retraction notices be linked to the retracted article wherever possible. So we can’t even tell you what the paper is about, outside of its title: “T1 transgenic tobacco plants carrying multicopy T-DNAs at the same locus exhibit various expression levels of transgenes.”

Here’s all we’ve got—the retraction notice itself: Continue reading Dude, whose gene is that? Genetics paper retracted for lack of permission

Double-dipping equals double retraction for fracking paper

tran por medTransport in Porous Media and the Journal of Petroleum Science and Engineering have retracted two articles on shale gas by Chinese researchers for duplication and other “mistakes.”

The articles came from a group at the State Key Laboratory of Oil and Gas Reservoir Geology and Exploitation at Southwest Petroleum University, in Chengdu. The articles share a corresponding author.

According to the abstract of the TPM paper, “Pressure Transient Analysis for Multi-stage Fractured Horizontal Wells in Shale Gas Reservoirs”:

The presented model could be used to interpret pressure signals more accurately for shale gas reservoirs.

Make that a double, according to its notice:

Undisclosed industry funding prompts correction of fracking paper

152 page minimum spine. Editor: Matt Hotze, JEM: Esther RTP:  Diane Murphy

Environmental Science & Technology has issued a correction for a March 2015 paper on methane contamination from gas wells after learning that the authors failed to disclose funding from Chesapeake Energy Corp., a major U.S. energy producer.

The paper, “Methane Concentrations in Water Wells Unrelated to Proximity to Existing Oil and Gas Wells in Northeastern Pennsylvania,” came from a group led by Donald Siegel, of Syracuse University. In the correction, Siegel acknowledges having received “funding privately” from Chesapeake for the study, which found: Continue reading Undisclosed industry funding prompts correction of fracking paper

Highly cited cancer researcher pulls review for “similar text and illustrations”

AbdomImaging_ak8The author of a 2006 review article published in Abdominal Imaging has retracted it because it hews too closely to previously published articles.

The review described the latest imaging techniques used in cancer, focusing on genitourinary conditions.

Here’s the full text of the retraction notice for “New Horizons in Genitourinary Oncologic Imaging”:

Drunk rats paper wasted by “significant statistical errors”, among other issues

MolBiolRep_ak5Authors from Xinxiang Medical University in Weihui, China, are retracting a 2014 paper in Molecular Biology Reports because… well, because lots of things.

The researchers exposed nine rats to acute levels of alcohol then compared them to unexposed mice rats, noting differences in gene expression and molecular pathways.

But no one is toasting these findings anymore. Here are the details behind the retraction, courtesy of the notice:
