Strategic Position

The issue of information diffusion in small-world social networks was first systematically brought to light by Mark Granovetter in his seminal paper “The Strength of Weak Ties” in 1973 and has been an area of active academic studies in the past three decades. This chapter discusses information proliferation mechanisms in massive online social networks (MOSN). In particular, the following aspects of information diffusion processes are addressed: the role and the strategic position of influential spreaders of information; the pathways in the social networks that serve as conduits for communication and information flow; mathematical models describing proliferation processes; short-term and long-term dynamics of information diffusion, and secrecy of information diffusion.

Strength Of Weak Ties

This paper presents and discusses some of the results of practical application of Social Network Analysis for Information (SNA) to a nonprofit organization, the publishing house Cidade Nova. The article starts by presenting the empirical and methodological options and refers the social networks basic terminology, after which the research procedures are detailed. Lastly, results from the actors Information Social Network (ISN) and from the complete ISN (where alters are included) are presented, to which were used degree, closeness and betweenness centralities, the strength of weak ties of Granovetter and the lambda (?) set measures.

Contact Frequency

This study investigated the instrumental value of resources embedded in online social networks. 49 primary participants solicited a total of 588 secondary participants who were asked to complete a modest task. Approximately 16 per cent of all secondary participants responded (N = 98) to the request. 8.5 per cent of weak ties responded and strong ties were about three times more likely to respond. Perceived reciprocity, contact frequency and a composite measure of tie strength were all positively related to enacted support.

The Relationship

This study explores whether social interaction with dissimilar others can lead to pro-environmental behavior. Dissimilar others are people who differ from the person in question (e.g., in terms of lifestyle or culture). While most research focuses on homogenous social networks (e.g., spatial communities), we explore the potential of network heterophily. Specifically, using data (n = 1370) from the Flemish Survey on Sociocultural Shifts, we examine the relationship between network heterophily and pro-environmental behavior (i.e., shopping decisions and curtailment behavior). Building on Granovetter’s study on ‘the strength of weak ties’, we emphasize the importance of social ties that provide novel information and social expectations. Through interaction with dissimilar others, people may create a heterogeneous network in which a diversity of information and social expectations with regard to pro-environmental behavior circulates. We expect that network heterophily may foster pro-environmental behavior. Our findings indicate that pro-environmental behavior may indeed be positively related to interaction with dissimilar others, partly because people with many dissimilar ties know more about environmental problems and are more concerned about them. This study therefore shows that network heterophily promotes pro-environmental behavior. The paper concludes with a discussion of the functionality of dissimilarity and some avenues for future research.
