Although interest in research utilization in the policy process has grown, how advocates strategically deploy different types of evidence to influence lawmakers remains not well understood. In this paper, we draw on the Advocacy Coalition Framework and the Narrative Policy Framework to show how various types of evidence—from empirical findings to personal anecdotes—were utilized by advocates during the 2 years leading to the passage of California’s historic 2010 law to extend foster care. The result was a generous and flexible entitlement policy passed with bipartisan support in the context of a recession, a state budget deficit, and an ambivalent governor. We find that leaders of a diverse advocacy coalition strategically showcased different types of evidence at specific moments in the legislative process. Each evidence type can be tied to a specific narrative element and strategy. Advocates first used research evidence to convince lawmakers of the policy’s effectiveness, then used professional expertise and benefit-cost analysis to convince them it would come at an acceptable cost, and finally used personal narratives to motivate them to act. We conclude that though benefit-cost analyses play an integral role in policymaking during a time of austerity, advocacy coalitions may still benefit from personal stories that lend emotional potency and urgency. 相似文献

Individuals are the single largest source of campaign contributions, yet we know little about their motivations. For instance, the existing literature questions whether individual contributors sophisticatedly differentiate among candidates according to policy positions, particularly among same‐party candidates. We analyze this issue by combining data from a new survey of over 2,800 in‐ and out‐of‐state donors associated with the 2012 Senate elections, FEC data on contributors’ professions, and legislative records. Three major findings emerge. First, policy agreement between a donor's positions and a senator's roll calls significantly influences the likelihood of giving, even for same‐party contributors. Second, there is a significant effect of committee membership corresponding to a donor's occupation; this holds even for donors who claim that other motivations dominate, but it does not appear to be motivated by an expectation of access. Third, conditional upon a donation occurring, its size is determined by factors outside a legislator's control. 相似文献

In federal systems, both state governments and firms have incentives to strategically locate polluting facilities where the environmental and health consequences will be borne as much as possible by residents of other jurisdictions. We analyze air polluter location in the United States using a spatial point pattern model, which models where events occur in latitude and longitude. Our analyses indicate that major air polluters are significantly more likely to be located near a state's downwind border than a control group of other industrial facilities, results that are robust to a wide variety of model specifications and measurement strategies. This effect is particularly pronounced for facilities with toxic air emissions. The observed pattern of polluter location varies systematically across states and time in ways that suggest it is responsive to public policy at both the national and state levels. 相似文献

This article examines whether the Citizens' Initiative (CI) in Finland has enhanced inclusion in processes of political agenda‐setting. Democratic innovations such as CIs have been proposed as a solution to the challenges facing Western democracies. CIs are expected to increase political inclusion by allowing citizens to set the political agenda and by mobilising otherwise marginalised or passive citizens. However, the empirical evidence on this proposition remains scarce. This study examines the impact of the CI in Finland on political inclusion. It relies on the Civic Voluntarism Model (CVM) to determine whether the CI mobilises citizens who otherwise tend to be less involved in political matters and thereby enhances inclusiveness. The data come from the Finnish National Election Study 2015 (FNES2015), which is a cross‐sectional representative survey conducted in the wake of the national parliamentary elections in April 2015. Logistic regression models are used in the article to examine the relative importance of socioeconomic resources and civic skills, psychological political engagement and recruitment networks. The results show that while users have many of the familiar traits of political activists, the CI also activates marginalised groups. Most importantly, young citizens are likely to support CIs and the Internet constitutes a central recruitment network. In this sense, the CI has helped increase democratic inclusiveness. 相似文献

A hallmark finding in the study of public opinion is that many citizens approach the political realm with one‐sided attitudes that color their judgments, making attitude change difficult. This finding highlights the importance of citizens with weak prior attitudes, since they might represent a segment of the electorate that is more susceptible to influence. The judgment processes of citizens with weak attitudes, however, are poorly understood. Drawing from dual‐process models in psychology, I test the idea that citizens with weak explicit attitudes rely on implicit attitudes as they render political judgments. I find support for this conjecture in experimental and observational data. There are two main contributions. First, I show that an important and understudied segment of the electorate arrives at political decisions via automatic (but nonetheless predictable) mental processes. Second, I characterize the conditions under which implicit political attitudes matter more and less. 相似文献
