1+1 “identical” math papers = retraction

homeHeaderTitleImage_en_USA paper on an equation useful in finance has been retracted after editors discovered an “identical” version had been published in another journal.

The paper, “On the Parametric Interest of the Black-Scholes Equation,” was published in the Thai Journal of Mathematics. According to the introduction, that equation has a practical use:

In financial mathematics, the famous equation named the Black-Scholes equation plays an important role in solving the option price of stocks

(According to The Guardian, it was “The mathematical equation that caused the banks to crash.”)

4th ORI-flagged paper by Oregon student is retracted

home_cover (2)The last of four papers containing data falsified by University of Oregon neuroscience student David Anderson has been retracted.

When the Office of Research Integrity report flagging the papers came out in July, Anderson told us he “made an error in judgment,” and took “full responsibility” for the misconduct.

The newly retracted paper, “A common discrete resource for visual working memory and visual search,” published in Psychological Science, has been cited 28 times, according to Thomson Scientific’s Web of Knowledge. According to the abstract, it demonstrates a possible link between working memory and the ability to “rapidly identify targets hidden among distractors.”

But according to the retraction note, Anderson produced “results that conformed to predictions” by “removing outlier values and replacing outliers with mean values”  in some of the data.

Here’s the retraction note in full:

Mirror image in plant study flagged on PubPeer grows into retraction

djs_mpmi_28_9_cover-online.inddA 2010 paper on plant fungus has been retracted after a comment on PubPeer revealed that a study image had been flipped over and reused to represent two different treatments.

In May, a commenter pointed out the plants in Figure 2a of the paper in the journal Molecular Plant-Microbe Interactions “look remarkably similar.” A commenter writing under the name of corresponding author, Yukio Tosa at Kobe University in Japan, posted a response two days later agreeing with the assessment and stating that the paper should be retracted.

The notice reads: Continue reading Mirror image in plant study flagged on PubPeer grows into retraction

Can you spot the signs of retraction? Just count the errors, says a new study

downloadClinical studies that eventually get retracted are originally published with significantly more errors than non-retracted trials from the same journal, according to a new study in BMJ.

The authors actually called the errors “discrepancies” — for example, mathematical mistakes such as incorrect percentages of patients in a subgroup, contradictory results, or statistical errors.

The study doesn’t predict which papers will eventually be retracted, since such discrepancies occur frequently (including one in the paper itself), but the authors suggest a preponderance could serve as an “early and accessible signal of unreliability.”

According to the authors, all based at Imperial College London, you see a lot more of these in papers that are eventually retracted: Continue reading Can you spot the signs of retraction? Just count the errors, says a new study

Here’s how to keep clinical trial participants honest (and why that’s a big deal)

NEJMAdditional lab tests, creating a clinical trial patient registry, and rewards for honesty are among the advice doled out in this week’s issue of the New England Journal of Medicine for researchers to help avoid the major issue of participants lying to get into clinical trials.

In the Perspective, David B. Resnik and David J. McCann, both based at the National Institutes of Health, address concerns raised by a 2013 survey of clinical trial participants that revealed “high rates” of “deceptive behavior.” Specifically: Continue reading Here’s how to keep clinical trial participants honest (and why that’s a big deal)

Duke researcher with 7 retractions earns two Expressions of Concern

American Journal of Respiratory and Critical Care MedicineData issues continue to plague pulmonary papers co-authored by Duke University professor William Foster and former Duke researcher Erin Potts-Kant. Yesterday, the American Journal of Respiratory and Critical Care Medicine posted an Expression of Concern for two articles from the pair while the findings are “under review.”

The notice was published after the paper’s corresponding author, John Hollingsworth (also at Duke), told the journal that “some of the data published in these articles may be unreliable,” a term that we’ve gotten used to seeing from previous retractions.

Another Expression of Concern from the journal published earlier this year for another paper co-authored by Foster and Potts-Kant turned into a retraction months later. Hollingsworth was a co-author on that paper and another paper retracted from Environmental Health Perspectives in July.

Top official at Indian university plagiarized most of paper

A top official and law researcher at a university in India is facing dismissal after being charged with plagiarizing approximately three-quarters of one of her papers, among other allegations.

Chandra Krishnamurthy, the Vice Chancellor at Pondicherry University, has been “placed under ‘compulsory wait’ by the Union human resource ministry following several charges against her,” according to The Times of India.

A nine-month long investigation by the International Journal of Legal Information confirmed that the majority of one paper on Krishnamurthy’s CV, “Legal Education and Legal Profession in India,” was largely plagiarized.

Here’s the retraction note:

Re-analysis of controversial Paxil study shows drug “ineffective and unsafe” for teens

downloadThe antidepressant Paxil isn’t safe or effective for teens after all, says a re-analysis of a 2001 study published today in The BMJ.

The original 2001 paper in Journal of the American Academy of Child and Adolescent Psychiatry — study 329, as it’s known — helped greenlight use of the drug (generically known as paroxetine) in young people. But it’s faced accusations of ghostwriting, undisclosed conflicts of interest, and issues with data analysis since publication.

According to a BMJ feature, also published today: Continue reading Re-analysis of controversial Paxil study shows drug “ineffective and unsafe” for teens

Fourth retraction for Einstein oncologist due to image manipulations

home_cover (1)Two papers on a potential cancer drug have been retracted following an investigation that found “inappropriate manipulation of bands in gels.”

This makes four retractions by our count for Roman Perez-Soler, an oncologist at the Einstein College of Medicine, and for co-author Yi-He Ling, whose current affiliation is unknown.

Their previous two retractions, which we reported on in 2013, were also for image manipulation. At the time, Perez-Soler told us that Ling “accepted full responsibility for the changes” and he had “returned to his home country.”

The fresh retraction notes, from Molecular Pharmacology, provide a few specifics about the figures that were manipulated this time around.

Kansas ecology prof loses whistleblower protection after alleging misconduct

ecologyThe U.S. government has denied whistleblower protection for a researcher who was fired from Kansas State University after alleging his colleagues misrepresented data in an ecology paper.

Researcher Joseph Craine was asked to leave K-State after being the “subject of a dismissal campaign” by colleagues when he told the Ecology journal that he believed some had been “fraudulently characterizing field studies,” according to the Topeka Capital-Journal.

In response, Craine sought whistleblower protection status from the National Science Foundation — a sponsor of the research — which was recently denied, says the Topeka Capital-Journal:
