This paper focuses on U.S. senators and their home‐state approval ratings from 1981 to 1997. We examine these ratings to assess the relative impacts of tactical factors, such as the senators' bill sponsorship and media activity, and contextual influences, such as economic performance, state population size, and the evaluations and behavior of other elected officials. We find that the senators' own tactical behavior affects the approval ratings, but a stronger influence is the context in which the senators operate.  相似文献

Three hypotheses have been used to describe the male propensity for sexual aggression towards women: a general propensity to offend, a specific propensity to sexually offend and a combination of both. In this paper, using structural equation modeling, we compared the relative utility of these three hypotheses in explaining criminal activity in adulthood of sexual aggressors of women. In total, 209 adult males who were convicted of at least one sexual offence were included in the study. Results indicate that a propensity model emphasizing the role of an early and persistent general propensity to act in an antisocial manner during childhood and adolescence is most adequate to explain sexual aggressors' criminal activity. After controlling for the role of this propensity, a specific propensity characterized by high sexualization and deviant sexual interests explained only a modest proportion of variance of the sexual criminal activity.  相似文献

Ministerial portfolios are the most obvious payoffs for parties entering a governing coalition in parliamentary democracies. This renders the bargaining over portfolios an important phase of the government formation process. The question of ‘who gets what, and why?’ in terms of ministerial remits has not yet received much attention by coalition or party scholars. This article focuses on this qualitative aspect of portfolio allocation and uses a new comparative dataset to evaluate a number of hypotheses that can be drawn from the literature. The main hypothesis is that parties which, in their election manifestos, emphasise themes corresponding to the policy remit of specific cabinet portfolios are more likely to obtain control over these portfolios. The results show that policy saliency is indeed an important predictor of portfolio allocation in postwar Western European parliamentary democracies.  相似文献

We use data from the National Incident‐Based Reporting System (NIBRS) to examine the effects of age on the risk of sexual and physical assault in prisons and jails. Our evidence suggests that male inmates of all ages tend to sexually assault young men. The preference for the young is much stronger for sexual than for physical assault, which suggests that the young are sexually assaulted because of their sexual attractiveness rather than because of their vulnerability. We argue that the strong relationship between sexual attractiveness and age reduces opportunities for consensual sex among older inmates. As a result of blocked opportunities for consensual sex, older men are much more likely to commit sexual assault than one would expect, given the general tendency of young men to be more violent. Thus, the age–attractiveness relationship can parsimoniously explain the contrasting age patterns one observes for offenders and victims.  相似文献

Prime ministers often have to work with prime ministerial aspirants, senior ministers who regard themselves as possible successors. But can these challengers seize the job when the prime ministers are reluctant to stand down? Using evidence from Canada, Britain and Australia, the article explores the conditions in which successions have taken place and the capacity of the prime ministerial aspirants to expedite the process. It identifies three alternative strategies that are shaped by the party rules in the different countries. The aspirants may flee, fight or fulminate. Which strategy will best improve their chances of winning the top job depends on the traditional or developing modes of leadership election that their parties have adopted. Some processes provide the means to assassinate the leader. Others have no opportunity to act; rivals can do nothing but wait, either in or outside parliament. The article finds that the broader the constituency that elects the leaders, the more secure those leaders are when their reputation declines.  相似文献

Existing studies have generally measured collective efficacy by combining survey respondents’ ratings of their local area into an overall summary for each neighborhood. Naturally, this approach results in a substantive focus on the variation in average levels of collective efficacy between neighborhoods. In this article, we focus on the variation in consensus of collective efficacy judgments. To account for differential consensus among neighborhoods, we use a mixed‐effects location‐scale model, with variability in the consensus of judgments treated as an additional neighborhood‐level random effect. Our results show that neighborhoods in London differ, not just in their average levels of collective efficacy but also in the extent to which residents agree with one another in their assessments. In accord with findings for U.S. cities, our results show that consensus in collective efficacy assessments is affected by the ethnic composition of neighborhoods. Additionally, we show that heterogeneity in collective efficacy assessments is consequential, with higher levels of criminal victimization, worry about crime, and risk avoidance behavior in areas where collective efficacy consensus is low.  相似文献

Since Hobbes (1957 [1651] and Beccaria (1963 [1764]), scholars have theorized that the emotion of fear is critical for deterrence. Nevertheless, contemporary deterrence researchers have mostly overlooked the distinction between perceived sanction risk and fear of apprehension. Whereas perceived risk is a cognitive judgment, fear involves visceral feelings of anxiety or dread. Equally important, a theory explicating the influence of deterrence on both criminal propensity and situational offending has remained elusive. We develop a theoretical model in which perceived risk and fear are distinguished at both the general and situational levels. We test this theoretical model with data from a set of survey‐based experiments conducted in 2016 with a nationwide sample of adults (N = 965). We find that perceived risk and fear are empirically distinct and that perceived risk is positively related to fear at both the general and situational levels. Certain background and situational factors have indirect effects through perceived risk on fear. In turn, perceived risk has indirect effects through fear on both criminal propensity and situational intentions to offend. Fear's inclusion increases explanatory power for both criminal propensity and situational offending intentions. Fear is a stronger predictor than either self‐control or prior offending of situational intentions to offend.  相似文献
