Seeing triple: Optics paper proves to be one of three, retracted

joptA team of physicists has lost their 2013 paper in the Journal of Optics after the publisher learned that the article had already appeared in print twice before.

The article, “Inscription of narrow bandwidth Bragg gratings in polymer optical fibers,” came from researchers at the Instituto de Telecomunicacoes, in Portugal, and the Aston Institute of Photonic Technologies, in Birmingham, England. Per the abstract: Continue reading Seeing triple: Optics paper proves to be one of three, retracted

Second retraction for chemist from Portugal who forged names, data

chemengjrnChemical Engineering Journal has retracted a 2011 article from a group of researchers in Portugal after determining that the scientists made up their data.

The clincher: According to the journal, the researchers did not possess the proper lab equipment to perform the study as reported.

The article, “Detoxification of high-strength liquid pollutants in an ozone bubble column reactor: Gas–liquid flow patterns, interphase mass transfer and chemical depuration,” appeared in August 2011 and was written by Rodrigo J. G. Lopes and Rosa M. Quinta-Ferreira, from the Group on Environmental, Reaction and Separation Engineering in the Department of Chemical Engineering at the University of Coimbra. The paper has been cited twice, according to Thomson Scientific’s Web of Knowledge, both times by the original authors.

Here’s what the abstract has to say about the work: Continue reading Second retraction for chemist from Portugal who forged names, data

A new plagiarism euphemism: “language from already published sources without using proper citation methods”

crestA recent issue of Critical Reviews in Environmental Science and Technology (CREST) adds a new euphemism for plagiarism to our rapidly growing list.

There are two retractions in the issue of the Taylor & Francis journal. One is for “Remediation of Heavy Metal Contaminated Soils: An Overview of Site Remediation Techniques,” by a group from Portugal: Continue reading A new plagiarism euphemism: “language from already published sources without using proper citation methods”

University of Lisbon investigation that spawned neuroscience retractions found no evidence of misconduct

j neuroscienceYesterday, we reported on two retractions in the Journal of Neuroscience whose notices referred to a University of Lisbon report that had determined there was  “substantial data misrepresentation” in the original articles.  The notice didn’t say anything about misconduct, but when we see “misrepresentation,” we tend to think — as do many others — that there had been funny business.

But we heard back this morning from the senior author of the study, Ana M. Sebastião, and there’s a lot more to this story. It turns out that the University of Lisbon committee that wrote the report concluded, unanimously, that Continue reading University of Lisbon investigation that spawned neuroscience retractions found no evidence of misconduct
