Editorial mix-up leads to duplication, retraction of physics paper

with one comment

A missed withdrawal request has ed to doubled up publication and a later retraction for Brazilian physicists, through no fault of their own.

Atmospheric Plasma Treatment of Carbon Fibers for Enhancement of Their Adhesion Properties” was presented at an Institute of Physics (IOP) conference in 2010. The proceedings weren’t published until May 2014.

In the meantime, the plasma scientists withdrew their paper from consideration and submitted it to IEEE Transactions on Plasma Science, where it was published in February 2013. Unfortunately, in the four year delay between the conference and the Institute of Physics publication, the withdrawal request got lost.

Here’s the notice: Read the rest of this entry »

Physicists with retraction for a “pattern that was unphysical” lose another for manipulation

with 6 comments

journal of applied physicsIn September, we wrote about the retraction of a physics paper for “a pattern that was unphysical.”

The team, whose first author, R.K. Singhal refused to sign the notice, has had another paper retracted, this one in the Journal of Applied Physics. Here’s the notice for “Study of electronic structure and magnetization correlations in hydrogenated and vacuum annealed Ni doped ZnO:” Read the rest of this entry »

Editor in chief steps down after being found plagiarizing in her own journal

with 12 comments

diab met syndImagine you were a cop, sitting in your squad car at the side of the road with a radar gun, when you clock someone speeding. You turn on your lights, pull the speedster over to the side of the road, and walk to her driver’s side window.

Just as you say “Driver’s license and registration, please,” you realize the driver is your squad captain. Oops.

That must have been something like what it was like — with plagiarism detection software sitting in for the radar gun — for the co-editor-in-chief of Diabetology & Metabolic Syndrome when he realized that Marilia de Brito Gomes, the other co-editor-in-chief, had published two papers in their journal that contained plagiarized passages.

Here’s the notice for “Historical facts of screening and diagnosing diabetes in pregnancy:” Read the rest of this entry »

Did article on doped indium contain a doped image?

with 5 comments

asscoverApplied Surface Science has retracted a 2010 paper by a group of researchers from India and Brazil because one of the figures in the article was suspect.

The paper was titled “Effect of hydrogenation vs. re-heating on intrinsic magnetization of Co doped In2O3.”

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 9 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 »
