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.

What’s the difference between plagiarism and “unintended and unknowing breach of copyright?”

In our work here at Retraction Watch, we’ve seen a number of euphemisms for plagiarism. (See slides 18-22 of this presentation for a selection.) Today, in following up on a case we covered last month, we’ve learned of a new way to avoid saying the dreaded p-word.

We reported in June that sex researcher Willibrord Weijmar Schultz had retracted two papers. One was for “substantial overlap between this paper and an earlier published paper by Talli Yehuda Rosenbaum,” while the other was for “breach of warranties made by the authors with respect to originality” and failure to cite a dissertation.

Two more retractions from Weijmar Schultz, for exactly the same reasons as the second one above, have just appeared. One was of a 1991 paper in Sexual and Marital Therapy (now Sexual and Relationship Therapy), while the other was of a 2003 article in the Journal of Sex & Marital Therapy.

The Journal of Sex & Marital Therapy notice reads as follows: Continue reading What’s the difference between plagiarism and “unintended and unknowing breach of copyright?”
