A third retraction stemming from Cardiff investigations

cancer research 1113We’ve been reporting on retractions of research published by Cardiff University scientists following an investigation into their work. On Monday, we noted a new retraction of work by the group in Cancer Research, which we thought was the second retraction following one in the Journal of Immunology in 2011. But it turns out there was another retraction published at the same time in the same journal, which we now know about thanks to commenter David Hardman and PubPeer.

“Just significant” results have been around for decades in psychology — but have gotten worse: study

qjepLast year, two psychology researchers set out to figure out whether the statistical results psychologists were reporting in the literature were distributed the way you’d expect. We’ll let the authors, E.J. Masicampo, of Wake Forest, and Daniel Lalande, of the Université du Québec à Chicoutimi, explain why they did that:

The psychology literature is meant to comprise scientific observations that further people’s understanding of the human mind and human behaviour. However, due to strong incentives to publish, the main focus of psychological scientists may often shift from practising rigorous and informative science to meeting standards for publication. One such standard is obtaining statistically significant results. In line with null hypothesis significance testing (NHST), for an effect to be considered statistically significant, its corresponding p value must be less than .05.

When Masicampo and Lalande looked at a year’s worth of three highly cited psychology journals — the Journal of Experimental Psychology: General; Journal of Personality and Social Psychology; and Psychological Science — from 2007 to 2008, they found: Continue reading “Just significant” results have been around for decades in psychology — but have gotten worse: study

Former Cardiff researcher found guilty of misconduct “very disappointed,” calls process “unprofessional”

cardiffYesterday, we reported on the second retraction in a case at Cardiff University, which had found misconduct by a former scientist. Cancer Research, which published the retraction, said that scientist, Rossen Donev, could not be reached.

Donev responded to our request for comment this morning: Continue reading Former Cardiff researcher found guilty of misconduct “very disappointed,” calls process “unprofessional”

Second retraction stemming from Cardiff investigations appears

cancer research 1113A second retraction of a paper by a Cardiff University researcher found to have committed misconduct has appeared.

In April, a Cardiff investigation found that Rossen Donev, a former researcher at the university, had manipulated images in four different papers. Donev, who was at the University of Swansea until August, according to his LinkedIn profile, and is now director of Biomed Consult Ltd., had already retracted a Journal of Immunology paper in late 2011 after a different Cardiff investigation.

The investigation cleared co-author and dean Paul Morgan of misconduct. Morgan resigned from Cardiff in August, but “he categorically denied that his decision had anything to do with the misconduct investigation,” according to Times Higher Education.

Here’s the new notice, from Cancer Research: Continue reading Second retraction stemming from Cardiff investigations appears

Spying on The Onion: Journal retracts drone paper for duplication

euro j agronomyWhen you think of drones, you probably think of deadly strikes in faraway lands. But what about studying crops?

Take “Use of digital photography from unmanned aerial vehicles for estimation of leaf area index in onion (Allium cepa L.),” a study published earlier this year in the European Journal of Agronomy by researchers from Spain: Continue reading Spying on The Onion: Journal retracts drone paper for duplication

Doing the right thing: Scientists reward authors who report their own errors, says study

scientificreportsWe’ve always like to highlight cases in which scientists do the right thing and retract problematic papers themselves, rather than being forced to by editors and publishers. Apparently, according to a new paper by economists and management scholars, scientists reward that sort of behavior, too.

The study by Benjamin Jones of the Kellogg School of Management at Northwestern University and the National Bureau of Economic Research and colleagues, “The Retraction Penalty: Evidence from the Web of Science,” was published yesterday in Scientific Reports, a Nature Publishing Group title.

The authors lay out what they do: Continue reading Doing the right thing: Scientists reward authors who report their own errors, says study

Two detailed retraction notices correct the cardiology record

jaccTwo American College of Cardiology conference abstracts published earlier this year in the Journal of the American College of Cardiology (JACC) have been retracted, one because the authors were actually measuring something other than what they reported, and the other because newer software invalidated the results.

Here’s the notice for “Worsening of Pre-Existing Valvulopathy With A New Obesity Drug Lorcaserin, A Selective 5-Hydroxytryptamine 2C Receptor Agonist: A Meta-Analysis of Randomized Controlled Trials” by Hemang B. Panchal, Parthav Patel, Brijal Patel, Rakeshkumar Patel, and Henry Philip of East Tennessee State University: Continue reading Two detailed retraction notices correct the cardiology record

Henry IV, part 2: No retraction necessary, say some authors of royal head identification paper

Last week, we reported that some of the authors of a 2010 paper in the BMJ claiming to have identified Henry IV’s head thought the study should be retracted based on new evidence. Some of the other authors have now responded to that call for retraction, which appeared on the BMJ’s site alongside the paper.

Philippe Charlier, the corresponding author of the original paper, and five of the original paper’s 15 co-authors conclude after reviewing the evidence that

Ask Retraction Watch: Is a t-test no longer publishable?

Another installment of Ask Retraction Watch:

Recently I heard a graduate student was told by their advisor, ‘Don’t do a t-test, it’s not publishable.’  This seems ridiculous to me as the t-test is a robust test to aid in answering a hypothesis.  So my question is: is a t-test no longer publishable?  And if so, is this true for higher tiered journals, or all peer-reviewed journals?

I would very much appreciate hearing the opinions of your readers on this issue – do they feel they need to run more ‘elaborate’ statistics (e.g., multivariate, modeling, etc.) in order for their research to be publishable?  And if so, do researchers knowingly violate the assumptions of these more elaborate statistical tests so they can be ‘publishable’?

Irony alert: Forensic experts have paper retracted for plagiarism

ijmbrTime to roll out the irony meter again.

A group of scientists from Uttar Pradesh, India, who study forensic bioinformatics have had a paper retracted for something that can generally be detected with a specialized form of forensic software: Plagiarism.

Here’s the notice for Kumar Ajay, Singh Neetu, Gaurav S.S. “Forensic Bioinformatics: An innovative technological advancement in the field of Forensic Medicine and Diagnosis,” signed by O.A. Sofola, editor-in-chief: Continue reading Irony alert: Forensic experts have paper retracted for plagiarism
