Thomas Hegghammer offers the text [PDF] of a recent lecture on in his recent research - sounds fascinating:
My lecture today has a fancy title, but it is basically about what jihadis do in their spare time. Before you sneak out the back door and tweet “underwhelming”, let me say that this is the most interesting topic I have ever worked on, and it is much more important than it seems. My main message today is this: the non-military activities of terrorist groups can shed important new light on how extremists think and behave. In fact, I’ll go so far as claiming that this topic is one of the last major, unexplored frontiers of terrorism research, one that merits an entire new research program. Although I’ll be talking mainly about the culture of jihadi groups, the perspective and concepts I present can be applied to any type of rebel group.
