Social influence and the diffusion of user-created content

Abstract: Social influence determines to a large extent what we adopt and when we adopt it. This is just as true in the digital domain as it is in real life, and has become of increasing importance due to the deluge of user-created content on the Internet. In this paper, we present an empirical study of user-to-user content transfer occurring in the context of a time-evolving social network in Second Life, a massively multiplayer virtual world.We identify and model social influence based on the change in adoption rate following the actions of one's friends and find that the social network plays a significant role in the adoption of content. Adoption rates quicken as the number of friends adopting increases and this effect varies with the connectivity of a particular user. We further find that sharing among friends occurs more rapidly than sharing among strangers, but that content that diffuses primarily through social influence tends to have a more limited audience. Finally, we examine the role of individuals, finding that some play a more active role in distributing content than others, but that these influencers are distinct from the early adopters.

Integration of targeted health interventions into health systems: a conceptual framework for analysis

Abstract: The benefits of integrating programmes that emphasize specific interventions into health systems to improve health outcomes have been widely debated. This debate has been driven by narrow binary considerations of integrated (horizontal) versus non-integrated (vertical) programmes, and characterized by polarization of views with protagonists for and against integration arguing the relative merits of each approach. The presence of both integrated and non-integrated programmes in many countries suggests benefits to each approach. While the terms 'vertical' and 'integrated' are widely used, they each describe a range of phenomena. In practice the dichotomy between vertical and horizontal is not rigid and the extent of verticality or integration varies between programmes. However, systematic analysis of the relative merits of integration in various contexts and for different interventions is complicated as there is no commonly accepted definition of 'integration'-a term loosely used to describe a variety of organizational arrangements for a range of programmes in different settings. We present an analytical framework which enables deconstruction of the term integration into multiple facets, each corresponding to a critical health system function. Our conceptual framework builds on theoretical propositions and empirical research in innovation studies, and in particular adoption and diffusion of innovations within health systems, and builds on our own earlier empirical research. It brings together the critical elements that affect adoption, diffusion and assimilation of a health intervention, and in doing so enables systematic and holistic exploration of the extent to which different interventions are integrated in varied settings and the reasons for the variation. The conceptual framework and the analytical approach we propose are intended to facilitate analysis in evaluative and formative studies of-and policies on-integration, for use in systematically comparing and contrasting health interventions in a country or in different settings to generate meaningful evidence to inform policy.

An Exploratory Examination of the Influence of National Culture on Cross-National Product Diffusion

Abstract: This study examines the direct influence of national culture on the cross-national diffusion of innovations. Focusing on seven technological innovations across 13 European countries, the authors use Hofstede's multidimensional approach to culture to investigate this relationship. They find support linking four cultural dimensions—individualism, masculinity, power distance, and long-term orientation—to cross-national product diffusion. The findings suggest that national culture explains a relatively sizable amount of variation in cross-national diffusion rates. The authors discuss theoretical and practical implications of these results, including prescriptive guidance with respect to product launch strategy and tactics.

Design of innovation policy through diagnostic analysis: identification of systemic problems (or failures)

Abstract: “Activities” in innovation systems are the determinants of the development and diffusion of innovations. Examples are RD it provides a framework for identification of systemic problems (or failures) in innovation systems.
