The University of Louisville has concluded that a much-questioned doctorate it awarded -- for one semester of study -- was legitimate, The Louisville Courier-Journal  reported. The doctorate was awarded to John Deasy in 2004 -- and appears to violate university rules about residency requirements. Deasy, as a school superintendent, had given money to a research center headed by the then-dean of Louisville's education college, who then went on to chair Deasy's dissertation committee, leading to questions about the legitimacy of the degree. But the university found that the "totality of the circumstances" indicated an appropriate process. At the same time, Louisville announced that it is tightening the procedures about exemptions from normal procedures for doctorates. The former dean, Robert Felner, was for years popular with administrators even as he angered many professors.  In October, he was indicted on 10 counts of mail fraud, money-laundering and income-tax evasion related to charges that he fraudulently obtained grants for Louisville and the University of Rhode Island. He has denied wrongdoing.
