connie allen & the yale chem dept

yale is planning not to renew the contract for one of the chemistry department lecturers. apparently it is time for her to "move on" according to the deputy provost. of course, since connie is a black woman (not to mention an excellent teacher and mentor) this does not bode well for yale's spoken commitment to faculty diversity. i know, i know, the pool of applicants is small and you guys are trying really hard. but wouldn't trying hard mean that you should at least retain the talented people that you already have?
