I've been trying to find the dissertation of someone who advertises that they hold a "doctorate of management" from the "University of Phoenix". The degree requires a dissertation, but the school does not require the dissertation to be published, apparently, because neither is the work listed on ProQuest, nor does the University's own library hold it. My liaison indicated that the author may have deliberately chosen not to distribute the work. I have not yet been able to obtain a copy.
Is this obscurantist practice rare at good universities & common at for-profit universities?
Any other factors at play in the unavailability of a graduate dissertation in the United States?
