A master's student at the University in Oslo, according to a report (in Norwegian) on the university home page, discovered that his instructor had published one of his texts in the August 2011 issue of Edda.
The master's student had written a hjemmeeksamen (take-home test) about the novel by Thure Erik Lund called Inn in 2009. The instructor published the article on the same topic. The master's student registered a complaint with the university ombud for good scientific practice and requested that the next possible issue of Edda publish a correction naming him as co-author.
The university investigated the matter. The professor said that he had apparently used the take-home test for the next course and had believed the text was his own. The university has found that the instructor must ensure that a correction is published, and that this publication will not count for tenure or be listed as a university publication.
I find it good that the university has published this, including the names of the participants, on the university home page. Thanks to Gunnar for the link!
