1G Social Network Analysis

Note: Readings for a given day are done in advance of that day, whilst exercises are performed the same day during or after class. Please note that the readings will not be discussed specifically in class. They are supplementary materials that well help complete your understanding of the topic. Readings marked "optional" are not in your reading packet nor linked on this page -- find them through your University library.

The class meets every day in room 5N 4.7 from 10:00am to 13:30. We typically move to the lab (A) around 12:00.
