Objectivos

Why do some organisations have self-destructive behaviours while others grow and innovate? Why do fans of a football team mostly hang out with fans of the same football team? Which strategies are used by corporate elites to increase their political and economic power? Why is difficult for an immigrant to integrate in the country of residence? Or why is it so easy for someone already rich to get richer? By using the method of social network analysis (SNA) we can answer questions as these. In this course, various types of social networks (intra and inter organizational) will be analysed as to understand socio-economic dynamics such as collective action, diffusion of information, interlocking directorships, elite formation, social capital development, etc. The software UCINET, NETdraw and Key player will be used.
