Researcher who called plagiarism “the worst type of fraud” retracts paper for…plagiarism

with 32 comments

arq brasAs a reporter on the police beat many years ago, one of us (Adam) used to hang out with a press officer whose desk at the station had the following sign: “Uma boca fechado não recolhe nenhum pé.”

At least, that’s what it would have been had we been in Rio. In Palmer Park, Maryland, the sign read: “A Closed Mouth Gathers No Foot.”

A group of Brazilian researchers has retracted their 2009 article on gut bacteria for plagiarism — but not before one of them decried such behavior as the nadir of scientific misconduct. Read the rest of this entry »

Should this engineering paper have been retracted?

with 26 comments

safetyscienceThe journal Safety Science has retracted a 2013 paper by a group of engineers from Brazil who had published the article previously, albeit in a much abbreviated form, a year earlier.

What makes this case more than a straightforward matter of duplication/self-plagiarism is that the authors greatly expanded upon the earlier article. The initial paper also appeared in a conference proceedings — the  18th World Congress on Ergonomics – Designing a Sustainable Future — priority that, at least in the minds of some, doesn’t really constitute a true publication.

A retracted retraction? Authors salvage entomology paper with image issues

with 8 comments

jtbThe paper is dead. Long live the paper!

Earlier this year, we brought you the case of a group of Brazilian insect researchers who lost two 15-year-old papers in different journals for duplication. One of those papers has been resurrected, albeit in a rather puzzling way.

The article, “Non-local interactions and the dynamics of dispersal in immature insects,” had appeared in the Journal of Theoretical Biology, which had issued the following retraction notice:

Medical journal guilty of citation manipulation retracts two “inadequate” review articles

with 30 comments

clinicsThe Brazilian medical journal Clinics — edited by the Faculdade de Medicina of the University of São Paulo — has lost two more papers in a citation stacking scheme that cost one of the authors his job as editor of the publication.

The first paper, by former editor Mauricio Rocha-e-Silva and Ariane Gomes, was titled “An overview of recently published medical papers in Brazilian scientific journals,” and was published in 2011. As the retraction notice states: Read the rest of this entry »

That’ll do it: Physics paper retracted for a “pattern that is unphysical”

with 8 comments

j phys dLast December, we brought you the story of a math paper that was retracted because it made “no sense mathematically.” Today, we have that retraction’s cousin: A physics paper retracted because some of the data are “unphysical.”

Here’s the notice for “Room temperature ferromagnetism in pure and Co- and Fe-doped CeO2 dilute magnetic oxide: effect of oxygen vacancies and cation valence,” which was published in April 2011 in the Journal of Physics D: Applied Physics: Read the rest of this entry »

The University of São Paulo and Brazil’s National Council of Technological and Scientific Development funding agency (CNPq) have cleared a researcher of fraud following a six-month investigation.

The CNPq’s Commission on Integrity in Scientific Activity noted, however, that “there was failure to exercise rigor in the conduct and dissemination of results [in Rui Curi's work], essential to quality research.” Read the rest of this entry »

A mega-correction for Rui Curi, whose lawyers threatened to sue Science-Fraud.org

with 103 comments

plos oneA Brazilian researcher whose legal threats helped lead to the shutdown of Science-Fraud.org and who has had two papers retracted has had to correct another paper.

The fourth correction for Rui Curi — and we’d call it a mega-correction — is of a paper in PLOS ONE. Curi is the fourth out of 11 authors; someone named Tania Pithon-Curi is the final author:

Like pulling teeth? Dental implant papers retracted for duplication

with 2 comments

jomscoverA group of Brazilian dental researchers has lost two 2012 papers for duplication — twice the typical body count for such situations.

The two articles appeared in the Journal of Orthodontics and the Journal of Oral and Maxillofacial Surgery about four months apart.

The first, from the JOMS, “Selective Use of Hand and Forearm Muscles During Bone Screw Insertion: A Natural Torque Meter,” was published online Aug. 30 — just about the time the Journal of Orthodontics was accepting the duplicate submission.

As the JOMS retraction notice states: Read the rest of this entry »
