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

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:

The 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 »
