The objective of this paper is to theoretically analyze how human interaction may evolve in a world characterized by the explosion of online networking and other Web-mediated ways of building and nurturing relationships. The analysis shows that online networking yields a storage mechanism...

Empirical studies have documented a decline in indicators of social participation in the last decades. The responsibility of social disengagement has been often attributed to pervasive busyness and the rising pressure of time. In this paper we argue that computer-mediated interaction, and...

Review of Immigrant Networks and Social Capital by Carl L. Bankston III. Cambridge, UK, and Malden, MA: Polity.

We use a unique dataset to study how participation in two specific types of nonprofit organizations, i.e. social welfare associations and social cooperatives, affects individual social capital. A descriptive analysis shows that both the types of organization have a positive impact. The...

Social media have been credited with the potential of reinvigorating trust by offering new opportunities for social and political participation. This view has been recently challenged by the rising phenomenon of online incivility, which has made the environment of social networking sites hostile...

The contribution of this paper to the social capital literature is threefold. It first develops an innovative framework for measuring social capital, which allows for quantification of five different components of the multidimensional concept of social capital. Secondly, it provides a single,...

The study of social networks, and in particular the spread of disease on networks, has attracted considerable recent attention in the physical and mathematical literature. In this paper, we show that a large class of standard epidemiological models, the so-called susceptible/infective/recovered...

The small-world network model is a simple model of the structure of social networks, which simultaneously possesses characteristics of both regular lattices and random graphs. The model consists of a one-dimensional lattice with a low density of shortcuts added between randomly selected pairs of...

A number of recent studies have focused on the statistical properties of networked systems such as social networks and the World-Wide Web. Researchers have concentrated particularly on a few properties which seem to be common to many networks: the small-world property, power-law degree...

A network is robust to the extent that it is not vulnerable to disconnection by removal of nodes. The minimum number of nodes that need be removed to disconnect a pair of other nodes is called the connectivity of the pair. It can be proved that the connectivity is also equal to the number of...
