This is an illuminating article from the Chronicle's monthly(?) magazine which compares sorority life at Duke with that of my own alma mater, UNC:

Having never been directly involved with a greek org at Duke (though I have many friends and acquaintances who have been and still are), I'm not really in a position to provide any valuable commentary on the climate of its system. However, I will say that, as an outside observer, it seems to me that sororities are rather disenfranchised by Duke's administration, especially as compared to the privileges given to fraternities and "selective living groups" (basically, groups that resemble local greek orgs without greek-letter names). Therefore, it's no real surprise to me that the author of the first article is struggling to find empowerment through her collegiate involvement in her sorority.
