Spring 2007 Schedule

Prof Steve Borgatti MB 813 Home


Assignments are due on the day they are listed (except for the very first class -- those readings should be read immediately after class). All items subject to change without notice. Please check the schedule frequently. Before printing articles, try reading them online. Is all that ink and toner really necessary?

Most of the links for journal articles require you to be logged in via your BC id in order to recognize you as legitimate members of the community. Click here for more information. The notation "LCG" is used to refer to the Lattin, Carroll and Green  text book. For example, "LCG 1,2" refers to chapters 1 and 2 of that book.
