Epidemic Potential in Human Sexual Networks: Connectivity and The Development of STD Cores
		Introduction • What features of networks matter? STD Cores • Definition • Implications for network structure Structural Cohesion • Definition • Cohesive Blocking: Structure & Position • Structural Cohesion = STD cores Three Questions: • Implications of Large Scale Net. Models • Empirical Evidence for Cohesive Cores • Development of Core groups in low-degree networks Future Extensions • Extension to dynamic networks
