The quality of Graduate Programmes is often associated with the scientific collaboration. This paper discusses how scientific collaboration processes can be identified and characterized through social and complex networks. For this purpose, collaboration networks of bibliographic production, research projects, and committees of PhD theses and Masters’ dissertations by researchers from a graduate program in computational modeling were studied. The data were obtained from CAPES’ reports of the period from 2001 to 2009. Among the studied indices, centrality indices indicate the presence of prominent researchers who influence others and promptly interact with other researchers in the network. The indices of complex networks reveal the presence of the small-world (i.e. these networks are favorable to increase coordination between researchers) phenomenon and indicate a behavior of scale-free degree distribution (i.e. some researchers promote clustering more than others) for one of the studied networks.展开更多

The goal of PET Saúde is to foster the formation of learning groups within the Family Health Strategy scope. While being studied at the city of Feira de Santana, the program was structured with one coordinator and eleven tutorial groups, distributed in 27 family health offices, which constituted a social network where the construction and knowledge diffusion occur. This article proposes the analysis of the information and knowledge flows of this network through the social networks analysis. This study highlights the play of PET Saúde’s coordinator in the processes of organization and articulation as central vertex of the network, and some scholars in the articulation of different tutorial groups. The results show a fragmentation in the PET Saúde network when the coordinator vertex is removed, whereas 5 components are generated where 4 tutorial groups appear isolated.展开更多

Classical approaches using Social Network Analysis indices do not account for this characteristic. We propose two new cohesion indices based on a clique approach, and we redefine the network density using an index of variance of density. We have applied these indices to two coauthorship networks, one comprising researchers that published in Mathematics Education journals and the other comprising researchers from a Computational Modeling Graduate Program. A contextualized and comparative analysis was performed to show the applicability and potential of the indices for analyzing social networks data.展开更多
