A recent article made me realize that it is not generally known that USNews.com has decided not to try to produce its own scholarly impact ranking, which will (happily) leave the field to Professor Gregory Sisk and colleagues at the University of St. Thomas (Minnesota) (their new study should be out next week).   Prior iterations of the Sisk study have already had a significant influence on faculty hiring, including at the University of Virginia–but more on that next week.
