Author objects to retraction for not “faithfully represented” immunology figures

The Journal of ImmunologyAll but one of the authors of a study about the immune response to H. pylori have agreed to a retraction in The Journal of Immunology, due to two of the paper’s figures not being “faithfully represented.”

Authors of the 2006 paper said they were unable to provide the original unedited scans “due to inadequate archiving dating back almost 10 years.” The authors — with the exception of the first author, Sushil Kumar Pathak, apologized for the error.

The notice, which has been appended to the pdf, reads:

Violent songs can lead to spicy food, and other lessons we learned from corrected graphic

S00221031

A correction to a 2011 paper doesn’t change its main conclusion: Hearing song lyrics about violence — “let the bodies hit the floor,” for example — can prompt aggressive behavior, even more so than violent imagery in music videos.

The correction follows an investigation by Macquarie University that found errors in data analysis to be an “honest mistake.”

During the study — “The effect of auditory versus visual violent media exposure on aggressive behaviour: The role of song lyrics, video clips and musical tone,” published in the Journal of Experimental Social Psychology — the authors measured the effect of violent songs or imagery using the “hot sauce paradigm.” In this model, researchers estimate people’s level of aggression by how much hot sauce they give another person to eat. The study found that, indeed, people who are exposed to violence — particularly, lyrics —  give more hot sauce to their neighbors. It has been cited 6 times, according to Thomson Scientific’s Web of Knowledge.

One aspect of the paper prompted a tweet from a Dutch journalist: Continue reading Violent songs can lead to spicy food, and other lessons we learned from corrected graphic

“Rigging of the peer-review process” kills parasite paper

s13369083k

A paper on nematode parasites appears to have been infected with a nasty strain of a publishing problem known as fake peer review. By our count, the phenomenon has felled approximately 250 papers in total.

The affected review, “The important role of matrix metalloproteinases in nematode parasites,” explores a type of enzyme secreted by the parasite. Published in Helminthologia, it’s been cited once, according to Thomson Scientific’s Web of Knowledge.

Unfortunately, the retraction note doesn’t give us too many details about how the peer review process was manipulated:

Predatory journals published 400,000 papers in 2014: Report

BMC medicineThe number of so-called “predatory” open-access journals that allegedly sidestep publishing standards in order to make money off of article processing charges has dramatically expanded in recent years, and three-quarters of authors are based in either Asia or Africa, according to a new analysis from BMC Medicine.*

The number of articles published by predatory journals spiked from 53,000 in 2010 to around 420,000 in 2014, appearing in 8,000 active journals. By comparison, some 1.4-2 million papers are indexed in PubMed and similar vetted databases every year.

These types of papers have become a major problem, according to Jeffrey Beall, a librarian at the University of Colorado Denver who studies the phenomenon: Continue reading Predatory journals published 400,000 papers in 2014: Report

Investigation finds “careless data workup” in alcoholism drug paper

S00142999

An investigation at Karolinska Institute has led to the retraction of a paper about drug treatments for alcoholics, after concluding the article contains a “very careless data workup.”

The paper, “Memantine enhances the inhibitory effects of naltrexone on ethanol consumption,” found that the drug memantine (normally used to treat Alzheimer’s) enhances the effects of naltrexone in rats, which blocks the high of alcohol.  It was published in the European Journal of Pharmacology and has been cited 10 times, according to Thomson Scientific’s Web of Knowledge.

However, its conclusion is now “unreliable,” according to the retraction note:

Should peer review be open, and rely less on author-picked reviewers? Study says…

BMJ openAfter reviewing hundreds of peer review reports from three journals, authors representing publishers BioMed Central and Springer suggest there may be some benefits to using “open” peer review — where both authors and reviewers reveal their identity — and not relying on reviewers hand-picked by the authors themselves.

But the conclusions are nuanced — they found that reviewers recommended by authors do just as good a job as other reviewers, but are more likely to tell the journal to publish the paper. In a journal that always uses open reviews — BMC Infectious Diseases — reviews are “of higher quality” than at a journal where authors are blinded to reviewers, but when one journal made a switch from a blinded to an open system, the quality didn’t improve.

Here’s what the authors conclude in the abstract of the paper, published today in BMJ Open: Continue reading Should peer review be open, and rely less on author-picked reviewers? Study says…

Following criticism, BMJ “clarifies” dietary guidelines investigation

downloadThe BMJ has issued two “clarifications” to an investigation it published last week that questioned whether the new U.S. dietary guidelines were evidence-based.

The article criticized several aspects of the new dietary guidelines, such as “deleting meat from the list of foods recommended as part of its healthy diets” — without, according to author Nina Teicholz, reviewing the scientific literature on meat. However, according to the clarification, that sentence should have specified “lean” meats.

After The BMJ‘s article appeared, an analysis on The Verge questioned whether Teicholz was guided by her own opinions. She’s the author of a book The Big Fat Surprise: Why Butter, Meat and Cheese Belong in a Healthy Diet. The Dietary Guidelines Advisory Committee also posted a lengthy “rapid response” — The BMJ‘s refined version of a comment section — to Teicholz’s article, saying it “strongly disagrees with many of the statements represented as facts.”

This afternoon, Rebecca Coombes, head of investigations and features at The BMJ, posted a response: Continue reading Following criticism, BMJ “clarifies” dietary guidelines investigation

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:

50 years later, is it time to retract a retraction by a Nobel prize-winning author?

Georg Wittig
Georg Wittig

It’s not often that an article is retracted only to be later proven correct. But that may have happened this past summer in the chemistry literature.

In July, a group of researchers recapitulated an experiment largely similar to one that Nobelist Georg Wittig had performed – and subsequently retracted — decades earlier. Their findings suggest Wittig may actually have gotten it right the first time.

On July 27, Peter Chen of ETH Zurich and colleagues published an article online in the journal Angewandte Chemie International Edition that describes a new method for appending a carbon atom to an unsaturated hydrocarbon to create a three-membered ring – a useful chemical transformation known as cyclopropanation. Yet, it was not the first time researchers had reported such a process. As Chen and his colleagues note in the Israel Journal of Chemistry, Georg Wittig of the Ruprecht-Karls-Universität Heidelberg (who would go on to win the chemistry Nobel Prize in 1979) and Volker Franzen reported a similar reaction in 1960 in Angewandte Chemie, a German-language publication.
