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...

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...

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

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...

Online social networks, such as Facebook, amplify the occasions for social comparisons which are detrimental to well-being. The authors test the hypothesis that the use of social networking sites (SNS) increases social comparisons using Italian data from the Multipurpose Household Survey, and...

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 random graph of Erdos and Renyi is one of the oldest and best studied models of a network, and possesses the considerable advantage of being exactly solvable for many of its average properties. However, as a model of real-world networks such as the Internet, social networks or biological...

We study some simple models of disease transmission on small-world networks, in which either the probability of infection by a disease or the probability of its transmission is varied, or both. The resulting models display epidemic behavior when the infection or transmission probability rises...

We study percolation on small-world networks, which has been proposed as a simple model of the propagation of disease. The occupation probabilities of sites and bonds correspond to the susceptibility of individuals to the disease and the transmissibility of the disease respectively. We give an...

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...
