This paper (30 page PDF) gets the prize for being one of the most complex papers to appear in IRRODL in recent memory, though (I think) reading closely makes it a little less complex than it first appears. The authors are assessing the efficiency of interaction networks with relation to knowledge-seeking and knowledge-demonstrating behaviour, and mapping this against subject-related talk and procedural talk. What do we find? "Courses with smaller enrollment numbers appear to struggle more with generating enough discussion and connecting knowledge seekers with knowledge disseminators (and) subject-related-talk-dominated discussion forums and procedural-talk-dominated discussion forums are significantly different in overall network efficiency and seeking tendency, but not in disseminating tendency."
