How does social capital matter to the creation of neighbourhood networks in cities? Social housing in Portugal is some times viewed as a single architectural and building environment development failure. This article discusses a relevant Portuguese urban planning landscape and aims to contribute to the discussion of one of its main purpose – the social housing experiment. The author discusses the case of this landscape as urban policy-making and evaluates its implementation and relevance. She hypothesizes that “neighbourhood units” have become a relevant case in the context of neighbourhood planning and housing social-mix in Lisbon. Firstly, she uses theoretical arguments and findings to discuss an urban experiment - Alvalade Landscape. Secondly, the paper analyses relevant data that demonstrates its links to the housing policies thus enriching the urban design. The article offers evidence from the Alvalade Landscape case study in Lisbon of theoretical and empirical community ties in the 1940s. Thirdly, the paper identifies some elements such as community units, social mix, sidewalks, and that have an impact on neighbourhood design as well as people’s lives. The findings show that supportive neighbour ties provide important network resources (social capital) concerning daily life, illness, support or financial aid. Finally, the paper suggests the relevance that social neighbourhood community has in housing programs and policies.
This chapter examines social networks in the Portuguese society, and the impact of these social networks on organizations regarding Computer-Mediated Communication. The results describe a Portuguese case study and attempt to answer the following question: How does Computer-Mediated Communication contribute to social networking in organizations? This chapter examines the emails and phone calls exchanged during the year 2008 by employees working for a Portuguese bank in order to identify nodes, roles, positions, types of relations, types of networks and centrality measures. Overall there were 93.654 internal calls and 542.674 emails exchanged between the actors. The findings suggest that emailing is the preferred means of communication, although frequency increases with hierarchy communication. Collaborative work between departments functions as the emergence of a network. The results confirm the relevance of computer networks to support social networks in organizations, and its potential concerning data analysis outside the traditional surveys, and the possibility of introducing Internet sources.
This paper provides a comprehensive overview of evolution and innovation in social network analysis to the paradigm of social networking. It explains how the development of sociological theory and the structural properties of social groups matter to computer science and communications. Authors such as Moreno, John Barnes and Harrison C. White provide evidence of a growing body of literature addressing the networking of people, organizations and communities to explain the structure of society. This perspective has passed from sociology to other fields, changing understandings of social phenomena. Social networks remain a potent concept for analyzing computer science and communications. This paper shows how and why this has occurred and examines substantive areas in which social network analysis has been applied-mainly how the advantages of graphic visualization and computer software packages have influenced SNA in different audiences and publics leading to the unfolding of social networking to different audiences and publics.
