Chutzpah: Authors blame PLOS ONE for failing to find plagiarism in paper on Botulinum toxin

plosonelogoHoly Chutzpah, Batman! A team of researchers in India has retracted their 2012 paper in PLoS One on botulinum toxin for plagiarism — while blaming the journal for failing to use its “soft wares” to catch the plagiarism.

The article, “Small-Molecule Quinolinol Inhibitor Identified Provides Protection against BoNT/A in Mice,” was written by a group from the Defence Research and Development Establishment, in Madhya Pradesh.

According to the retraction notice: Continue reading Chutzpah: Authors blame PLOS ONE for failing to find plagiarism in paper on Botulinum toxin

Fredrickson-Losada “positivity ratio” paper partially withdrawn

am psychIn 2005, Barbara Fredrickson and Marcial Losada published a paper in American Psychologist making a bold and specific claim:

…the authors predict that a ratio of positive to negative affect at or above 2.9 will characterize individuals in flourishing mental health.

The paper made quite a splash. It has been cited 360 times, according to Thomson Scientific’s Web of Knowledge, and formed the basis of a 2009 book by Fredrickson, Positivity: Top-Notch Research Reveals the 3 to 1 Ratio That Will Change Your Life.

But something didn’t sit right with Nick Brown, a psychology grad student at the University of East London. He found the paper’s claims wanting, and contacted Alan Sokal — yes, that Alan Sokal, who published a fake paper in Social Text in 1996. Sokal agreed, and he, Brown, and Harris Friedman published a critique of the paper in July of this year in American Psychologist. Its abstract: Continue reading Fredrickson-Losada “positivity ratio” paper partially withdrawn

Doing the right thing: Researchers retract quorum sensing paper after public process

We’ll say it again: We like being able to point out when researchers stand up and do the right thing, even at personal cost.

In December 2011, Pamela C. Ronald, of the University of California, Davis, and colleagues published a paper in PLOS ONE,”Small Protein-Mediated Quorum Sensing in a Gram-Negative Bacterium.” Such quorum sensing research is a “hot topic” right now, so not surprisingly the paper caught the attention of other scientists, and the media, including the Western Farm Press. The study has been cited eight times, according to Thomson Scientific’s Web of Knowledge.

One of those scientists who took notice was Ronald’s UC Davis colleague Jonathan Eisen, who posted about the paper on his blog. That was on January 9, 2012. But if you go to that post today, you’ll see that Eisen struck through most of it, and added this comment: Continue reading Doing the right thing: Researchers retract quorum sensing paper after public process

Real problems with retracted shame and money paper revealed

sjdmLast month, we reported on a retraction in Judgment and Decision Making that said “problems were discovered with the data.” At the time, corresponding author Wen-Bin Chiou, of National Sun Yat-sen University in Taiwan, told us that a research assistant who had since left the lab hadn’t kept questionnaires used in the research, making replication impossible.

But it turns out that wasn’t the whole story of “Shame for money: Shame enhances the incentive value of economic resources,” to put it charitably. We’ve now heard from people familiar with the case and can provide a fuller account.

The problems with the paper, according to our source, Continue reading Real problems with retracted shame and money paper revealed

What happened to Joachim Boldt’s 88 papers that were supposed to be retracted?

a&amisconductcoverCHICAGO — Almost two years after editors at 18 journals agreed in March 2011 to retract 88 of former retraction record holder Joachim Boldt’s papers, 10% of them hadn’t been retracted.

That’s what Nadia Elia, Liz Wager, and Martin Tramer reported here Sunday in an abstract at the Seventh International Congress on Peer Review and Biomedical Publication. Elia and Tramer are editors at the European Journal of Anaesthesiology, while Wager is former chair of the Committee on Publication Ethics (COPE).

As of January 2013, nine of the papers hadn’t been retracted, Tramer said, while only five — all in one journal — had completely followed COPE guidelines, with adequate retraction notices, made freely available, along with  PDFs properly marked “Retracted.” From the abstract (see page 18): Continue reading What happened to Joachim Boldt’s 88 papers that were supposed to be retracted?

Papers on potential cancer drugs retracted for image manipulation

ccr 9-13A group of researchers at the Einstein College of Medicine in the Bronx, New York has retracted two papers for image manipulation.

The retraction notices for “PM02734 (Elisidepsin) Induces Caspase-Independent Cell Death Associated with Features of Autophagy, Inhibition of the Akt/mTOR Signaling Pathway, and Activation of Death-Associated Protein Kinase” and “The Phosphatase Inhibitor Menadione (Vitamin K3) Protects Cells from EGFR Inhibition by Erlotinib and Cetuximab” say the same thing: Continue reading Papers on potential cancer drugs retracted for image manipulation

Too much skin in the game, as duplications force retraction of psoriasis paper

actadermA group of dermatology researchers from Egypt who passed around a psoriasis paper like a bottle of sunscreen at the beach have been burned (sorry) by a journal that caught them in the act.

Acta Dermatovenerologica Alpina, Pannonica et Adriatica is retracting the 2009 article “Association of cytokine gene polymorphisms with psoriasis in cases from the Nile Delta of Egypt” after discovering that they were far from the first publication to print the paper.

Here’s the retraction notice (it’s a pdf): Continue reading Too much skin in the game, as duplications force retraction of psoriasis paper

Frontiers papers on GMO debate, diabetes retracted for improperly cited text

frontiers plantThe author of a review article on diabetes has been forced to retract the paper after it emerged that he failed to properly credit some of the text — an omission we generally associate with the word plagiarism.

The article, “Colonic flora, probiotics, obesity and diabetes,” was written by Paul Marik, of Eastern Virginia Medical School, and appeared in July 2012 in Frontiers in Endocrinology. It has been cited once, according to Thomson Scientific’s Web of Knowledge.

Here’s the retraction notice:

Sir, that’s not my colon: Journal has a bite of a chicken and egg problem

Case report: An 85-year-old man eats some chicken and unknowingly swallows a bone. After two days of worsening abdominal pain, he shows up to the emergency room. A CT scan reveals the bone perforating his colon. He is rushed to surgery, which is successful. Then, during his otherwise uneventful recovery, he develops female breasts.

That’s not exactly the case report that showed up in the International Journal of Surgical Case Reports earlier this month, but then again, the images in the relevant case report aren’t exactly of someone’s colon, either.

With a warning that the clinical images below are mildly NSFW, here’s Figure 1 from the cleverly titled “Chicken or the leg: Sigmoid colon perforation by ingested poultry fibula proximal to an occult malignancy:” Continue reading Sir, that’s not my colon: Journal has a bite of a chicken and egg problem
