TL;DR: In this paper, the authors investigate two rural populations of Indian and Kenyan potters who have to decide whether to adopt new, objectively more efficient and economically more attractive, technical/stylistic options.
Abstract: The recent literature on “complex contagions” challenges Granovetter’s classic hypothesis on the strength of weak ties and argues that, when the actors’ choice requires reinforcement from several sources, it is the structure of strong ties that really matters to sustain rapid and wide diffusion. The paper contributes to this debate by reporting on a small-N study that relies on a unique combination of ethnographic data, social network analysis, and computational models. In particular, we investigate two rural populations of Indian and Kenyan potters who have to decide whether to adopt new, objectively more efficient and economically more attractive, technical/stylistic options. Qualitative field data show that religious sub-communities within the Indian and Kenyan populations exhibit markedly different diffusion rates and speed over the last thirty years. To account for these differences, we first analyze empirically observed kinship networks and advice networks, and, then, we recreate the actual aggregate diffusion curves through a series of empirically calibrated agent-based simulations. Combining the two methods, we show that, while single exposure through heterophilious weak ties were sufficient to initiate the diffusion process, large bridges made of strong ties can in fact lead to faster or slower diffusion depending on the type of signals circulating in the network. We conclude that, even in presence of “complex contagions,” dense local ties cannot be regarded as a sufficient condition for faster diffusion.

TL;DR: In this article, the authors discuss the impact of market competition on the diffusion of new communication technologies, and the broad-scale impacts of this interaction include a shift in the social evaluation of newness and a shortening of product life cycles.

TL;DR: In this article, a quali-quantitative approach is employed to tackle the content of the administered semi-structured interviews and to map them into a connected set of nodes representing concepts as provided by the selected informants.

TL;DR: In this article, an excellent opportunity to assess such a diffusion is provided in sub-Saharan Africa where a series of changes in governmental regimes had been brought about by explicit or implicit uses of force.
Abstract: social communication network. The geographic scale within which such diffusion processes occur is localized. While less extensive, there also are some empirical studies that have dealt with the diffusion of innovations within regional and national settings [3; 9; 18; 23]. Characteristically, such studies are concerned with the spread of new techniques, organizations, or ideas over large geographic areas; often the adopting unit is a business, a city, or some other institution. Another distinguishing feature of diffusion processes at this geographic scale is that innovations are thought to filter down the urban hierarchy. By contrast, those at the international scale are extremely small in number, and even fewer deal with the spatial diffusion of political phenomena. However, an excellent opportunity to assess such a diffusion is provided in sub-Saharan Africa where a series of changes in governmental regimes had been brought about by explicit or implicit uses of force. Most of the countries in the sub-Saha-

TL;DR: The Rape Prevention and Education (RPE) Program's theory model, Creating Safer Communities: The Rape Prevention Education Model of Community Change, provides family social workers with a framework for examining and changing the individual and social factors that lead to sexual violence as mentioned in this paper.
Abstract: Social work practice has long focused on the connections between an individual and the social environment that affect the individual's social functioning. The Rape Prevention and Education (RPE) Program's theory model, Creating Safer Communities: The Rape Prevention and Education Model of Community Change, provides family social workers with a framework for examining and changing the individual and social factors that lead to sexual violence. This model connects two societal change theories, community readiness and diffusion of innovations, with three individual level theories, theory of reasoned action, theory of planned behavior and the health belief model, for the purpose of ending sexual violence. The Centers for Disease Control and Prevention (CDC) created this theory model to promote the use of theory-based prevention strategies among RPE Program grantees. In this article the authors (1) describe the theoretical underpinnings of the RPE theory model; (2) explore how one RPE grantee, supported with f...
