About us

The Center of Theory and Methods of Social Network Analysis has been founded by Prof. Andrea Salvini, and a group of researchers and scholars in 2007 at the University of Pisa, Department of Political Science.

The Center is one of the national poles in the sociological field, having a longtime tradition in the areas of Third Sector, Social Capital, Social Work, School and Education, Religion, and Interactions. We also work on qualitative methods, and on qualitative network analysis.

The core activities are different, mainly devoted to combine research and education. We edited an introductive monograph on Social Network Analysis (Pisa University Press, 2007), a successful collective book (FrancoAngeli, 2009), and many other publications on social phenomena and social relationships. The Center organized three International Workshops on Social Network Theory and Methods (2009, 2011, 2013), and a Spring School on Methods of Social Network Analysis with R (2020). We are currently involved in projects and research activities, also in partnership with Institutions, Universities, (public and private) Organizations, both in Italy and abroad.

You’ll find more info about all the previous lines in the related sections of our website.

Due to the particular situation with regard to the spreading of the Covid-19, the Spring School on “Methods of Social Network Analysis with R“, scheduled for April 20 to 24, is temporarily suspended.

The decision is necessary to protect everyone’s health and to encourage a more serene and less difficult participation. The hypothesis on which we are working on is to realize the Summer School from July 6 to 10 or the following week. Further information will be provided shortly. Those who have already paid will be refunded their fees if they are not available to participate on the dates that will be scheduled. Please contact the organizers for details.

The new application deadline is: 31 May 2020.

Abstract. Social Network Analysis is a useful technique for studying emergent behaviours of cooperation, intervention and governance in inter organizational networks. In this work, an empirical study of two networks of organizations operating in local territories in Southern Italy and focusing on Third Sector and welfare activities is presented. The actors are committed to experimenting a model of coordinated intervention induced by two corresponding egos which are local Caritas centres. The nodes of the two graphs are determined by combining egonetwork and whole-network approaches. The weighted edges representing mutual knowledge and collaboration between nodes are determined through interviews with all actors of the local groups. It is shown that metric properties of the networks can be useful indicators to monitor and evaluate endogenous features, e.g. relational and structural embeddedness, and exogenous features characterized by homophili mechanisms. The analysis provides insights on the networks governance of the social interacting organizations and reliable descriptors of the social processes that govern their functioning.
