16 pages., Via online journal., This study explores potential factors that lead to environmental opinion leadership behaviors such as informing the public about environmental issues and encouraging preventative behaviors among various social groups. Building on the theoretical framework of the diffusion of innovations model, these analyses explore the effects that mass media may have on perceptions of self-efficacy among opinion leaders and how self-efficacy may, in turn, encourage leaders to communicate about aquatic invasive species (AIS) to others in their social networks. Results indicate that mass media and governmental media can have both a positive and negative influence on levels of self-efficacy, and that opinion leaders with higher levels of self-efficacy are more likely to participate in behaviors that could potentially influence their social network(s). These findings not only highlight factors that influence opinion leadership regarding advocacy of environmental behaviors, but also offer insights as to how future campaigns can work with these groups to promote prevention strategies.
13 pages., Via online journal., Access to food is a basic pillar of human development. It is therefore unsurprising that it features so centrally on global development agendas and that a robust, interdisciplinary literature seeks to examine its determinants. This study focuses on the relationship between mobile technology and food access. Specifically, we ask whether mobile technology can strengthen the relationship between food access and certain social and political factors such as remittance flows and political participation. We use Afrobarometer surveys and highly disaggregated data on 2G network coverage to estimate a multilevel model testing how increased connectivity measured by mobile technology influences food access. We show that mobile phone use and higher frequency of use are significantly and positively correlated with food access, but we do not find evidence that remittances and political participation levels can explain the mechanisms linking mobile technology and food access. The study highlights that connectivity can play a powerful role in shaping food outcomes even when controlling for commonly identified impediments such as income constraints or physical isolation. These findings suggest that policies aimed at improving food access should devote attention to strengthening both communication and physical infrastructure.
