You are cordially invited to submit a contribution to "Collective
Behaviors and Networks", a one-day satellite event of the 2013
European Conference on Complex Systems (ECCS'13), to be held in
Barcelona, September 19, 2013.

Goal of this workshop is to provide a discussion venue about advances
in the study of networks applied to the dynamics of social collective
behaviors. Particular attention will be devoted, but not limited to,
the following topics:

- Group formation, evolution and group behavior analysis.
- Modeling, tracking and forecasting dynamic groups in social
media.
- Community detection and dynamic community structure analysis.
- Social simulation, cultural, opinion, and normative dynamics.
- Empirical calibration and validation of agent-based social
models.
- Models of social capital, collective action, social movements.
- Coevolution of network and behavior.
