Thanks, Don, for the plug. In the article he referred to (cite below) I 
analyze observational data (who spoke to whom and when in business 
meetings) in conjunction with network questionnaire data. My premise is 
that behavior--including but not limited to conversational behavior--is 
subject to myriad constraints that complicate and even confound the 
translation of subjective ties (e.g. who considers whom a friend) into 
observed behavior. I didn't QAP the matrices but never expected them to 
correlate well, since ties only engender behavior insofar as the flow of 
action creates the right opportunities. My approach was to ask whether 
particular conversational behaviors (such as talking to someone after 
they address the group) were especially likely to coincide with 
pre-existing network ties controlling for the distribution of 
conversational opportunities. The cite:

Gibson, D. R. (2005). "Taking Turns and Talking Ties: Network Structure 
and Conversational Sequences." American Journal of Sociology 110(6): 
1561-97.

I explore a similar problem in another recent article, where I simulate 
dyadic encounters given starting ("friendship") networks and scheduling 
constraints--the fact that if you're here you can't be somewhere else. 
(As one anonymous reviewer noted, it's ironic that we're only now 
discovering scheduling constraints given that electronic communication 
is relieving them somewhat. Point taken, if you're out there.) Not 
surprisingly, the behavioral network doesn't look a whole lot like the 
friendship network, especially around central people. More surprising 
are the consequences for diffusion. That cite:

Gibson, D. R. (2005). "Concurrency and Commitment: Network Scheduling 
and its Consequences for Diffusion." Journal of Mathematical Sociology 
29: 295-323.
