Bills signed into law in Pennsylvania last week include what some observers are calling the most sweeping changes in the State System of Higher Education since its formation, in 1982, The Philadelphia Inquirer reported. One change eases a conflict-of-interest clause that had barred professors at the system’s 14 universities from commercializing products derived from their research. Another clears the way for the universities to begin offering doctorates. (Those restrictions did not apply to Pennsylvania State University and three other state-related universities.) Faculty leaders were optimistic, but said they hoped the universities’ focus would remain on teaching and not shift too heavily toward research.
