Targeted Cooperative Actions Shape Social Networks

Origin and Structure of Dynamic Cooperative Networks

Societies are built on social interactions among individuals. Cooperation represents the simplest form of a social interaction: one individual provides a benefit to another one at a cost to itself. Social networks represent a dynamical abstraction of social interactions in a society. The behaviour of an individual towards others and of others towards the individual shape the individual's neighb...

Dependency in Cooperative Boolean Games

Cooperative boolean games are coalitional games with both goals and costs associated to actions, and dependence networks for boolean games are a kind of social networks representing how the actions of other agents have an influence on the achievement of an agent’s goal. In this paper, we introduce two new types of dependence networks, called the abstract dependence network and the refined depen...

Cooperative Networks in Interorganizational Settings: Analyzing Cyber-Collective Action

As evident in the mass protests during the Arab Spring and the Occupy movements, social media based platforms tremendously helped the protesters spread messages, organize, and mobilize support for their campaigns. The emergence of these cybercollective movements has driven much attention and frequently made headlines in the news. These instances of collective actions are documented as mere jour...

The narrow gap between norms and cooperative behaviour in a reindeer herding community

Cooperation evolves on social networks and is shaped, in part, by norms: beliefs and expectations about the behaviour of others or of oneself. Networks of cooperative social partners and associated norms are vital for pastoralists, such as Saami reindeer herders in northern Norway. However, little is known quantitatively about how norms structure pastoralists' social networks or shape cooperati...
