What types of researchers are most likely to recycle text? The answers might surprise you

Willem Halffman
Serge Horbach

Historians, economists, biochemists, psychologists: Who reuses their own material most often? Does the rate depend on how many authors a paper has, and how far along a researcher is in his or her career? Serge Horbach and Willem Halffman at Radboud University Nijmegen in the Netherlands tried to answer these questions by reviewing more than 900 papers published by researchers based in The Netherlands. And they were surprised by their findings, published last month by Research Policy.

Retraction Watch: How does the amount of text recycling you identified among researchers at Dutch universities (6.1%) compare to what other studies have shown among other groups of researchers?

Dutch university ordered to pay economist after she was accused of plagiarism

VU UniversityA court in the Netherlands has fined Vrije Universiteit Amsterdam (VU) 7,500 euros to compensate for “immaterial damage” to an economist accused of plagiarism.

Karima Kourtita researcher at VU, has been at the receiving end of anonymous complaints to her institution accusing her of plagiarism and her professor, high-profile economist Peter Nijkamp, of duplication (i.e. self-plagiarism). Kourtit is now seeking to prosecute the unnamed source of the complaint for defamation; the VU told us it will no longer accept fully anonymous complaints.

The case began when VU cancelled Kourtit’s thesis defense for plagiarism, and a report published on the VSNU, the Association of Universities, accused Nijkamp of self-plagiarism.

Peter Nijkamp

The Free University of Amsterdam found Peter Nijkamp, one of the nation’s leading economists who has lost several papers for self-plagiarism, has been found guilty of “questionable research practices,” according to the newly released results of an investigation.

Nijkamp has published a strongly worded criticism of the report (at least according to Google Translate, since his writing is in Dutch).

According to independent student publication Ad Valvas, the commission, led by Jaap Zwemmer, a professor emeritus at the University of Amsterdam, found Nijkamp was guilty of “questionable research practices.” University rector Frank van der Duyn Schouten, on the other hand, said in an official statement that there was “insufficient basis” to claim questionable research practices for each article.

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.
