The characterization of complex networks is a procedure that is currently found in several research studies. Nevertheless, few studies present a discussion on networks in which the basic element is a clique. In this paper, we propose an approach based on a network of cliques. This approach...

In the literature of social networks, understanding topological structure is an important scientific issue. In this paper, we construct a network from mobile phone call records and use the cumulative number of calls as a measure of the weight of a social tie. We extract skeletons from the...

We present a dynamical model for the spread of HIV in a finite discrete population of size n represented by the set V. The model takes into account the structure of the sexual network, the density of infected population in each individual’s sexual partners, and a reasonable amount of the...

We explain a possible mechanism of an information spreading on a network which spreads extremely far from a seed node, namely the viral spreading. On the basis of a model of the information spreading in an online social network, in which the dynamics is expressed as a random multiplicative...

The paper gives a theoretical framework for social capital theory under the consideration of social media. Three components exist to explain the causal mechanism in social network sites under the consideration of the social capital theory, which is the technological design, institutional design...

(English) In this working paper we have collected some working notes for the development of an interdisciplinary research on the interaction of Italian teenagers with the scientific information available on the Internet. Despite Internet results to be the main instrument of information of...

This paper investigates the relationship between a CEO’s social network, firm identity, and firm performance. There are two competing theories that predict contradictory outcomes. Following social network theory, one would expect a positive relation between social networks and firm...

In Chinese cities, rural migrants on average are less educated and poorer than the urban locals. Migration is costly, especially for those who choose to move to provinces faraway from their hometowns. A larger fraction of the rural migrants are self-employed than that of the urban locals. The...

As a common practice, various firms initially make information and access to their products/services scarce within a social network; identifying influential players that facilitate information dissemination emerges as a pivotal step for their success. In this paper, we tackle this problem using...
