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

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:

Authors retract leptin paper due to “fabricated data”

CellPress_ak2The authors of a study on the effects of the hormone leptin on the liver have retracted it from Cell Metabolism, almost four months after the Office of Research Integrity (ORI) determined it contained faked data, courtesy of its first author.

However, the authors say that the paper’s conclusions remain valid, and are supported by new experiments and additional research by outside groups.

Here’s more from the retraction notice: Continue reading Authors retract leptin paper due to “fabricated data”

Public health expert Stephen Leeder has been ousted as editor of Australia’s top medical journal after he questioned the decision to outsource the journal’s production and other tasks to publishing giant Elsevier.

Leeder, emeritus professor at the University of Sydney, told the Medical Observer he was asked to leave when he and the journal’s publisher, AMPCo, couldn’t see eye to eye on the decision:

Drug study pulled after researchers admit altering trial protocol

egypt anaesthesiaThe Egyptian Journal of Anaesthesia is retracting a 2014 paper by a pair of researchers at Cairo University who appear to have tinkered with their protocol after having received ethics approval.

The paper, titled “Can Sugammadex improve the reversal profile of Atracurium under Sevoflurane anesthesia?” was written by Heba Ismail Ahmed Nagy and Hany Wafik Elkadi, both in the department of anesthesiology.

Sugammadex, or Bridion, is given to rapidly reverse the effects of drugs that keep patients motionless during surgery. It is available throughout the world but not, as it happens, in the United States, where the Food and Drug Administration has refused to approve the agent because of fears that it might provoke severe allergic-like reactions.

According to the retraction notice:

Snail egg article retracted for fishing for material from six other papers

APJTB_ak1The first author of a review article on extracting pharmacological compounds from marine organisms, published in the Asian Pacific Journal of Tropical Biomedicine, has retracted it due to plagiarism.

There were also some authorship issues, according to the retraction notice for the paper, which absolves the last author, based at Pondicherry University in India, from responsibility:

This article has been retracted at the request of the Editor-in-Chief and the First Author. Both the first author and the journal’s editor confirmed that Dr. A Yogamoorthi is not responsible for the plagiarism since his/her name was added without consent.

There is one other author, R. Siva Sankar, also based at Pondicherry. Somewhere along the way, according to the retraction note, the paper scooped up wording from six papers previously published by researchers in Australia. Here’s more from the retraction note for “Antimicrobial secondary metabolites from marine gastropod egg capsules and egg masses”: Continue reading Snail egg article retracted for fishing for material from six other papers

Skeleton crew’s second paper broken over methodology issues; more retractions to appear

Olga Panagiotopoulou, via University of Queensland

Bone researcher Olga Panagiotopoulou of the University of Queensland has lost a second paper over “errors in the validation protocol and data.”

The retracted paper in the Journal of Biomechanics, about primate jaws, was subject to an expression of concern in May 2014 November 2013, one of two Panagiotopoulou’s group issued last year over methodological problems. The other paper was later retracted. According to Panagiotopoulou, there will be two more retractions forthcoming, both in the Journal of Anatomy. 

According John Hutchinson, last author of the other retracted paper, that withdrawal was the result of an investigation at his school, the Royal Veterinary College.

Panagiotopoulou emailed us with an explanation:

Cancer team loses two papers for image manipulation

bba_2A team spread across multiple institutions in China and McGill University in Canada has retracted two cancer papers over “inaccurate and inappropriately processed Western Blots.”

Some of the figures were also reused between the two articles, both in Biochimica et Biophysica Acta General Subjects.

The articles both tested the cancer-fighting properties of a derivative of the active compound present in Boswellia serrata gum resin.
