The reason: Image manipulation — which the authors say didn’t materially affect the conclusions of the paper.
The article, “FAK mediates the activation of cardiac fibroblasts induced by mechanical stress through regulation of the mTOR complex,” came from a group led by Ana Paula Dalla Costa, from the State University of Campinas.
We spoke with International Journal of Biometeorology editor-in-chief Scott Sheridan about the case: Read the rest of this entry »
A missed withdrawal request has led 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.
In 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 »
Imagine 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.
The paper was titled “Effect of hydrogenation vs. re-heating on intrinsic magnetization of Co doped In2O3.”
Not-so-tiny ethics issues as Micron retracts first-ever paper, and authors apologize for five duplicates
Denis de Jesus Lima Guerra, a co-author on 11 chemistry papers that were retracted in 2011 for suspicions of fraud, has lost his position at the Federal University of Mato Grosso (UFMT).
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 »
The 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.
