Despite its rich tradition, there are key limitations to researchers' ability to make generalizable inferences about state policy innovation and diffusion. This paper introduces new data and methods to move from empirical analyses of single policies to the analysis of comprehensive populations of policies and rigorously inferred diffusion networks. We have gathered policy adoption data appropriate for estimating policy innovativeness and tracing diffusion ties in a targeted manner (e.g., by policy domain, time period, or policy type) and extended the development of methods necessary to accurately and efficiently infer those ties. Our state policy innovation and diffusion (SPID) database includes 728 different policies coded by topic area. We provide an overview of this new dataset and illustrate two key uses: (i) static and dynamic innovativeness measures and (ii) latent diffusion networks that capture common pathways of diffusion between states across policies. The scope of the data allows us to compare patterns in both across policy topic areas. We conclude that these new resources will enable researchers to empirically investigate classes of questions that were difficult or impossible to study previously, but whose roots go back to the origins of the political science policy innovation and diffusion literature.
To what extent has the growth of Evangelicalism in Latin America contributed to political participation across the region? A number of scholars of religion and politics in the United States have suggested that Evangelicalism promotes the development of civic skills necessary for political engagement, while the Catholic Church, due to its hierarchical structure, provides fewer opportunities for skill acquisition. In this paper, we apply this debate to Latin America to test whether civic skills developed in Catholic and Protestant church activities lead to differential participation rates in 18 countries. We utilize the 2014 Pew Religion in Latin America survey to test these effects, and find that Protestant churches do indeed promote skill‐developing activities at higher rates, but that Catholics, when involved, are more likely to translate this religious participation into political action. We conclude that political scientists must better understand the organizational role of religion in promoting political engagement worldwide.
While a growing literature within the study of subjective well-being demonstrates the impact of socio-political factors on subjective well-being, scholars have conspicuously failed to consider the role of the size and scope of government as determinants of wellbeing. In this study, we examine the size of the public sector as a determinant of crossnational variation in life satisfaction across the industrial democracies. At the individuallevel, we find that public employees are happier and exhibit greater life satisfaction than otherwise similar others. At the aggregate level, the data strongly suggest that the subjective well-being varies positively with the size of the public sector. The implications for the study of life satisfaction are discussed.
The American religious landscape is transforming due to a sharp rise in the percentage of the population that is nonreligious. Political and demographic causes have been proffered but little attention has been paid to the current and potential political impact of these “nones,” especially given the established link between religion, participation, and party politics. I argue that the political impact of nonreligious Americans lies in an unexplored subset of the nonreligious population called committed seculars. Committed seculars de-identify with religion, they adopt secular beliefs, and join organizations structured on secular beliefs. Using a unique survey of a secular organization, the American Humanist Association, I demonstrate that committed seculars are extremely partisan and participatory, and are driven to participate by their ideological extremity in relation to the Democratic Party. These results point to a long-term mobilizing dimension for Democrats and indicate the potential polarizing influence of seculars in party politics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
