Author who threatened to sue Retraction Watch has another paper withdrawn

cureusBenjamin Jacob Hayempour, the researcher who threatened to sue us for asking questions about a retraction for plagiarism, has had another paper withdrawn.

The paper, published online in the journal Cureus, was titled “Novel Determinants of Tumour Radiosensitivity Post-Large-Scale Compound Library Screening” and had been available at http://www.cureus.com/articles/2394-novel-determinants-of-tumour-radiosensitivity-post-large-scale-compound-library-screening since January 13, but that URL now redirects to Cureus’s homepage.

We asked Cureus editor-in-chief John Adler for details, and he responded: Continue reading Author who threatened to sue Retraction Watch has another paper withdrawn

Another retraction for former record holder Joachim Boldt

bjaWith all the fuss about Yoshitaka Fujii, the current record holder for most retractions, you can be forgiven for forgetting that Joachim Boldt once owned that title, at least for about a year.

Well, Boldt has another retraction, although he’d need to double his tally (which is in the range of 90) to match Fujii’s “impressive” haul.

The new paper is, well, old, having been published in 1996, some 14 years before Boldt’s tribulations began. The article was titled “Influence of different volume therapy regimens on regulators of the circulation in the critically ill.” It appeared in the British Journal of Anaesthesia, and has been cited 45 times, according to Thomson Scientific’s Web of Knowledge.

According to the notice: Continue reading Another retraction for former record holder Joachim Boldt

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

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

Karel Bezouška, who broke into lab to tamper with investigation, has JACS paper retracted

jacsat_v136i001.inddKarel Bezouška, who, as we noted last year “broke into a lab refrigerator so he could tamper with samples being used to try to replicate the experiments during the investigation,” has had his fourth paper retracted.

Here’s the notice, for “Synthesis of Multivalent Glycoconjugates Containing the Immunoactive LELTE Peptide: Effect of Glycosylation on Cellular Activation and Natural Killing by Human Peripheral Blood Mononuclear Cells,” in the Journal of the American Chemical Society (JACS): Continue reading Karel Bezouška, who broke into lab to tamper with investigation, has JACS paper retracted

Dutch economist Nijkamp embroiled in plagiarism and duplication scandal

The Dutch papers are reporting that Peter Nijkamp, one of the leading economists in The Netherlands, has been embroiled in what looks like a self-plagiarism scandal following the cancellation of a thesis defense by one of his graduate students because of plagiarism.

We say “what looks like” because it’s tough to figure out what’s alleged here, given our reliance on translations. Best we can tell, the allegations against his graduate student are for plagiarism, while those against Nijkamp are for duplication, a.k.a. self-plagiarism.

According to the Google translation of this piece in our friends at the Volkskrant: Continue reading Dutch economist Nijkamp embroiled in plagiarism and duplication scandal

First retraction appears in case of cardiologist Poldermans

EBPOM_00219_M3Don Poldermans, the cardiology researcher in the Netherlands whose prominent career came to disgrace in a rather confusing scandal, finally has a retraction.

Poldermans, formerly of Erasmus Medical Center, copped to charges of misconduct but not of fraud in the case — which, if you speak Dutch, you can read about in detail here.

As we wrote in 2012: Continue reading First retraction appears in case of cardiologist Poldermans

Another retraction for sex researcher Weijmar Schultz

Willibrord Weijmar Schultz, the Groningen sex researcher (and Ig Nobel winner) who misused the 1985 thesis of an American scholar, and the work of another researcher, in at least five published articles, has tallied another retraction in the affair, his sixth.

As we reported earlier, Schultz had been cleared of plagiarism but found to have abused the work (in an “unintended and unknowing” fashion, we’re told) of one Diana Jeffrey, by taking passages from her dissertation without acknowledgement. These articles are pretty long in the tooth, having been published in the 1990s.

The latest, in the Journal of Sex Education and Therapy, appeared in 1992. Titled “Sexual rehabilitation after gynecological cancer treatment,” Schultz wrote it with a colleague H.B.M. Van de Wiel, whose name shows up on the other retractions, too.

According to the notice: Continue reading Another retraction for sex researcher Weijmar Schultz
