Retractions have arrived in the case of Peter Nijkamp, a leading Dutch economist accused of duplication and plagiarism. The Review of Economic Analysis has removed two of Nijkamp’s articles for self-plagiarism.
According to the NRC Handelsblad website (courtesy of Google translate):
The affair university economics professor Peter Nijkamp and his PhD student Karima Kourtit has escalated. The editors of the journal Review of Economic Analysis (RoEA) appears to have withdrawn because of self-plagiarism two scientific articles (reuse your own work earlier without acknowledgment), NRC Handelsblad discovered last week at the RoEA website.
The website reports that “significant parts” of the reclusive articles have appeared in other publications Nijkamp and Nijkamp / Kourtit, “without reference orderly” earlier. It involves work Nijkamp alone and work of VU economist Frank Bruinsma with Nijkamp and Kourtit.
Science reported last week that Jens Förster, the former University of Amsterdam social psychologist embroiled in data fabrication controversy, may have stumbled in his defense by muddling the timeline of his disputed studies in public statements.
The real challenge to Förster’s timeline may lie in e-mails between him and Pieter Verhoeven, his research assistant at UvA from September 2008 to June 2009, who made the correspondence available to Förster’s accuser. In it, the two discuss how to conduct what are evidently the same experiments Förster’s blog declares were completed much earlier in Bremen. For instance, among the stimuli used are three unintelligible audio recordings, which the 2011 paper says were described to the subjects as “Moldavian” poems. In an 18 May 2009 e-mail, Verhoeven comes up with the idea to describe the poem that way, rather than as Malaysian, because the reader of the poem has a German accent.
But in a yet another lengthy open letter to colleagues and friends, Förster insists that he conducted the studies in Germany before coming to the University of Amsterdam. And he hints darkly at the end that those seeking to cast doubt on his research may be doing so for personal gain: Read the rest of this entry »
Last November we wrote about the retraction of a 2010 paper in PNAS by Annemie Schuerwegh and colleagues. Schuerwegh had been fired from Leiden University in The Netherlands for fraud, which said there would be a second retraction coming.
The article, “Anti-citrullinated protein antibodies in rheumatoid arthritis: a functional role for mast cells and basophils?” had appeared in the Annals of the Rheumatic Diseases. According to the retraction notice: Read the rest of this entry »
Dirk Smeesters, the former Erasmus University psychology researcher found to have committed misconduct, is up to half a dozen retractions.
Both notices, in the Journal of Consumer Research, where Smeesters has already had one retraction, are paywalled. Here’s one, for a paper cited seven times, according to Thomson Scientific’s Web of Knowledge: Read the rest of this entry »
Jens Förster, the Dutch social psychologist accused of misconduct, has posted an open letter on his lab’s website in which he denies wrongdoing.
The letter, in English and dated May 11, offers a detailed rebuttal to the investigation’s conclusions. It also offers a rationale for Förster’s decision not to post his data on the Internet. And it’s followed by a briefer letter from Nira Liberman, who identifies herself as a collaborator of Förster’s.
We present the letter in full below:
Last week we wrote about the 2012 complaint that triggered the investigation into Jens Förster, the social psychologist at the University of Amsterdam whose work has come under scrutiny for possible fraud.
Now we have the findings of the official investigation by Landelijk Orgaan Wetenschappelijke Integriteit (the Dutch National Board for Scientific Integrity, often referred to as LOWI) — which clearly indicates that the institution believes Förster made up results.
We have obtained a copy of the report that led to the investigation of Jens Förster, the social psychologist at the University of Amsterdam, which is calling for the retraction of a 2012 article by the researcher for manipulated data.
As we reported earlier, Förster has denied any wrongdoing in the matter.
Retraction Watch has obtained an email from Jens Förster, the social psychologist in the Netherlands who, as Dutch media reported this week, was the target of a misconduct investigation at the University of Amsterdam. The inquiry led to the call for the retraction of a paper by Förster and a colleague, Markus Denzler, over concerns of data manipulation.
Förster denies those claims and said Denzler was not involved in the heavy lifting for the study in question: Read the rest of this entry »
