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

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:

Biologist banned by second publisher

TF

Plant researcher Jaime A. Teixeira da Silva has been banned from submitting papers to any journals published by Taylor & Francis. The reason: “continuing challenges” to their procedures and the use of “inflammatory language.”

This is the second time Teixeira da Silva has been banned by a publisher —  last year Elsevier journal Scientia Horticulturae told him that they refused to review his papers following “personal attacks and threats.”

Apparently, Taylor & Francis has too become frustrated with Teixeira da Silva’s communication strategy. Anthony Trioli, from Taylor & Francis, told Teixeira da Silva in an email (to which Teixeira da Silva copied us on his reply) that they would no longer accept his papers:

Marine mammal injury study retracted for using restricted gov’t data

Integrative ZoologyA 2012 paper that analyzed injuries to aquatic mammals in China has been retracted “due to the usage of restricted data from the Ministry of Agriculture of China.”

The authors — from Shandong University in China, The University of Hong Kong and the Peruvian Centre for Cetacean Research — “organized the collection of official documents related to strandings, bycatches and injuries of aquatic mammals in the waters of mainland China from provincial fishery administrations for the years 2000 to 2006,” according to the abstract. However, they may not have been supposed to do that.

Here’s the retraction notice from Integrative Zoology (which is paywalled, tsk, tsk):

Crime journal’s meteoric rise due to questionable self-citation: analysis

JCJShould it be a crime for editors to cite work in their own journal?

Last year, the Journal of Criminal Justice became the top-ranked journal in the field of criminology, but critics say that its meteoric rise is due in part to the editor’s penchant for self-citation.

As Thomas Baker of the University of Central Florida, writes in the September/October issue of the The Criminologist, a newsletter of the American Society of Criminology: Continue reading Crime journal’s meteoric rise due to questionable self-citation: analysis

Plagiarism count for mathematician updated to four papers

S00220396After we reported on a retraction for a 13-year old paper by Mohammed Aassila, a reader alerted us to two retractions and an editorial notice for the mathematician. Each of the notes is several years old.

That makes a total of four problematic papers for Aassila. Each is plagued by the same thing: plagiarism.

Here is the retraction note for “The influence of nonlocal nonlinearities on the long time behavior of solutions of diffusion problems,” published in the Journal of Differential Equations:

Stem cell researcher Jacob Hanna’s correction count updated to 10

Thanks to some eagle-eyed readers, we’ve been alerted to some corrections for high profile stem cell scientist Jacob Hanna that we had missed, bringing our count to one retraction and 13 errata on 10 papers.

The problems in the work range from duplications of images, to inadvertent deletions in figures, to failures by his co-authors to disclose funding sources or conflicts of interest. Hanna is the first or last author on 4 of the papers, and one of several on the rest.

First up, a correction to a Cell paper on which Hanna is the first author:

NSF investigation of high-profile plant retractions ends in two debarments

A nearly ten-year-long series of investigations into a pair of plant physiologists who received millions in funding from the U.S. National Science Foundation has resulted in debarments of less than two years for each of the researchers.

The NSF Office of Inspector General recently posted its close-out report on its decision and a review of the University’s investigation, which had recommended a total of eight retractions or corrections. Although the investigator’s names have been redacted, the text of retractions and corrections quoted in the report corresponds to papers by Continue reading NSF investigation of high-profile plant retractions ends in two debarments

Retraction of grizzly bear-diabetes study follows departure of Amgen scientist for data manipulation

cov150h
The retracted paper made the cover of the August 2014 issue of the journal.

A study that looked to hibernating bears to understand the mechanisms behind diabetes has been retracted because an author based at the biotech company Amgen “manipulated specific experimental data” in two figures.

According to the The Wall Street Journal, Amgen discovered the manipulation while reviewing the data following publication of the paper,”Grizzly bears exhibit augmented insulin sensitivity while obese prior to a reversible insulin resistance during hibernation.” Published in Cell Metabolism last year, the paper has been cited 8 times, according to Thomson Scientific’s Web of Knowledge.

A press release from the journal last year — coverage in Science and Nature followed — explained the purpose of the study:

Former UCSF grad student fudged data in two papers

ORIA former graduate student at the University of California, San Francisco “knowingly falsified and/or fabricated” data in two published papers, according to the Office of Research Integrity.

According to a case summary published this morning, Peter Littlefield was working on his PhD, studying the ways that cells respond to external signals, when he published the two problematic papers. He is the first author on the papers; Natalia Jura, whose lab he worked in, is the last on both.

The report’s findings are based on, among other sources, “the respondent’s admission.”

The first paper, “Structural analysis of the EGFR/HER3 heterodimer reveals the molecular basis for activating HER3 mutations” was published in Science Signaling and has been cited twice, according to Thomson Scientific’s Web of Knowledge.

Three figures in the paper are problematic, says the ORI summary:
