About half of the nations that experience civil war eventually relapse into renewed conflict within a few years after the original war ends. This observation has motivated a stream of research into the factors that affect the risk of peace failure in the aftermath of civil war. While the outcome of the previous civil war—for example, military victory versus peace agreement—structures the post-war environment in ways that affect the risk of peace failure, the capacity of the post-war state to enact and implement policies that affect the incentives for and capacity of groups to undertake armed violence as a means of advancing their interests should also affect the risks of peace failure. Using Geddes’ categories of nondemocratic regime types, we will present a theory of how different regime types have varying capacities to repress and/or implement accommodative policies that affect the risk of peace failure. We test propositions derived from this theory with a series of event history models. Our findings suggest that while peace agreements significantly increase the duration of post-civil war peace, peace agreements involving some types of nondemocratic regimes actually increase the risk of post-civil war peace failure.  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

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

This article reviews recent advances in the study of the European Court of Justice (ECJ) and its political impact at the European and member state levels. New quantitative as well as qualitative analyses show with great empirical precision that member state preferences guide the Court. The article summarises these findings, but argues that greater attention needs to be given to the (over-)constitutionalisation of EU law in order to fully capture the political impact of ECJ jurisprudence. Even if European judges are less activist than is often assumed and individual decisions are more restrained in the face of member state opposition, incrementally, case law evolves in a highly expansive fashion. And, exercising caution regarding unrealistic expectations about quasi-deterministic judicial law-making, it is found that the Court’s constitutionalised jurisprudence impacts heavily on European and member state policy-making.  相似文献

This study of the state frontline workforce breaks new ground by conducting an institutional analysis of rule abidance in the People's Republic of China (PRC). We draw upon a survey (n = 1,721) of Chengguan officers, the main players in regulatory enforcement of civil law in urban China, to explore the influence of autocratic one‐party rule on the meaning of and variation in rule abidance in China. The majority of Chengguan officers are rule followers, and demographic differences show little deviation from this norm. However, institutional factors associated with one‐party rule, particularly upward accountability, the privilege of administrative rank, and unequal access to power and resources, are significant in shaping differences in rule following among Chengguan officers. We conclude with a discussion of the similarities in institutional pressures on urban regulatory policing in China and the United States.  相似文献

Attachment, affect, and sex shape responsivity to psychosocial stress. Concurrent social contexts influence cortisol secretion, a stress hormone and biological marker of hypothalamic–pituitary–adrenal axis activity. Patterns of attachment, emotion status, and sex were hypothesized to relate to bifurcated, that is, accentuated and attenuated, cortisol reactivity. The theoretical framework for this study posits that multiple individual differences mediate a cortisol stress response. The effects of two psychosocial stress interventions, a modified Trier Social Stress Test for Teens and the Frustration Social Stressor for Adolescents were developed and investigated with early adolescents. Both of these protocols induced a significant stress reaction and evoked predicted bifurcation in cortisol responses; an increase or decrease from baseline to reactivity. In Study I, 120 predominantly middle-class, Euro-Canadian early adolescents with a mean age of 13.43 years were studied. The girls’ attenuated cortisol reactivity to the public performance stressor related significantly to their self-reported lower maternal-attachment and higher trait-anger. In Study II, a community sample of 146 predominantly Euro-Canadian middle-class youth, with an average age of 14.5 years participated. Their self-reports of higher trait-anger and trait-anxiety, and lower parental attachment by both sexes related differentially to accentuated and attenuated cortisol reactivity to the frustration stressor. Thus, attachment, affect, sex, and the stressor contextual factors were associated with the adrenal-cortical responses of these adolescents through complex interactions. Further studies of individual differences in physiological responses to stress are called for in order to clarify the identities of concurrent protective and risk factors in the psychosocial stress and physiological stress responses of early adolescents.  相似文献
