SOCZKA, Luis. Social networks in the process of diffusion of information: From Granovetter’s model to the model of Flache‑Macy. Psicologia [online]. 2005, vol.19, n.1-2, pp.251-262. ISSN 0874-2049.

In any facet of human activity the problem of the channels for innovation diffusion and information transmission must be dealed with. Innovation diffusion is a concept directly linked to the science system and not only to technological or market objects, since innovation objects may also be ideas, new models or theories. In this work the author analyze Granovetter’s “strength of weak ties” and Flache­‑Macy’s social network diffusion models, putting forward that diffusion operates through social networks and those must be seen as the strategic arena for the analysis of social influence studies in the science system.
