Link formation pattern during emergency response network dynamics

This study aims to understand the mechanisms of emergency response network evolution by quantitatively examining the link formation pattern among participants involved in a real emergency collaboration network. This is achieved by identifying the participants’ characteristics which can affect forming new links over time. The result indicates the existence of cumulative advantage process, where highly connected participants gain more new links over time. It also reveals the structural position of participants involved in a response network, i.e. brokering position, affects their number of future links. Understanding the link formation pattern is important for understanding the mechanisms of network evolution which help predict more precisely the behavior of actors and dynamics of network structure over time. This can assist researchers, decision makers and practitioners to manage and support the collaboration of actors in their systems in order to reach their organizational goals. The overall findings can contribute further to the development of network organizational theory in different contexts especially disaster and emergency response management.
