In Norway, self plagiarism has been a hot topic. Should it be treated as "ordinary" plagiarism if a student re-uses parts of an earlier assignment they have written themselves? And more generally, is it okay for institutions to provide commercial institutions copies of the work of students who cannot say no? To what degree should students be in control of what happens to their work (i.e., can they put some kind of license to it, to limit what it is used for)? Should the students be compensated when their papers are used to increase the value (i.e., database) of a third-party company?
