Dave Hoffman (Temple) has details here.  Already, the leading figure in the Tulane Philosophy Department has left because of the Katrina disaster. Faculty recruitment and retention, together with student recruitment and retention, will surely be crucial issues for Tulane over the next year or two.  Assuming there are no more flooding fiascos, I would expect Tulane to largely succeed on both fronts in the long run, though I imagine there will be other losses in the immediate future.
