ABSTRACTCampus sexual assault (SA) policies and sexual consent definitions have not been widely studied. The study team conducted a nationally representative review of college and university websites (n = 995), assessing the prevalence of publicly accessible online policies and definitions and examining associations with school characteristics. A content analysis was performed on a subsample (n = 100) of consent definitions. Most schools (93.0%) had an SA policy and consent definition (87.6%) available online. Schools were more likely to have a policy or consent definition if they were large (≥5,000 students), public, or had a female enrollment of ≥33%. Detail and comprehensiveness of definitions varied. Findings highlight opportunities for schools—especially small schools, private schools, and those with more male students—to increase access to SA policies and consent definitions. 相似文献

Though political scientists generally understand the origins of native‐born reactions to foreigners, less is known about how anti‐immigrant contexts trigger a political response within immigrant groups. I address this question by studying the connection between xenophobic rhetoric and Latino politics. I claim that xenophobic rhetoric raises the salience of ethnic identity and impugns its worth. This identity threat leads high‐identifying group members to engage in political efforts that assert their group's positive value, whereas low identifiers shun political opportunities to bolster their group's devaluation. I test these claims with an experiment embedded in a nationally representative opinion survey of Latino adults. In light of xenophobic rhetoric, I find that relative to low identifiers, high‐identifying Latinos become less politically trusting, more ethnocentric, and increasingly supportive of policies that emphasize ingroup pride. These results clarify xenophobic rhetoric's role in amplifying the influence of ethnic identity on immigrant politics. 相似文献

Performance‐Related Pay and the Crowding Out of Motivation in the Public Sector: A Randomized Field Experiment

This article advances our understanding of the effects of monetary rewards on public employee performance and of the contingencies that may moderate these effects. In a randomized control‐group experiment with nurses working at a local health authority in Italy, performance‐related pay (PRP) had a larger effect on task performance when the rewards were kept secret than when they were disclosed. The negative interaction between PRP and visibility was stronger among participants who were exposed to direct contact with a beneficiary of their efforts, which heightened their perception of making a positive difference in other people's lives. These results are consistent with theoretical predictions that monetary incentives for activities with a prosocial impact may crowd out employee image motivation. There were no crowding‐out effects when a symbolic reward was substituted for the monetary incentive. 相似文献

Chief Justice Roberts's Health Care Decision Disrobed: The Microfoundations of the Supreme Court's Legitimacy

The 2012 challenge to the Affordable Care Act was an unusual opportunity for people to form or reassess opinions about the Supreme Court. We utilize panel data coupled with as‐if random assignment to reports that Chief Justice Roberts's decision was politically motivated to investigate the microfoundations of the Court's legitimacy. Specifically, we test the effects of changes in individuals' ideological congruence with the Court and exposure to the nonlegalistic account of the decision. We find that both affect perceptions of the Court's legitimacy. Moreover, we show that these mechanisms interact in important ways and that prior beliefs that the Court is a legalistic institution magnify the effect of updating one's ideological proximity to the Court. While we demonstrate that individuals can and did update their views for multiple reasons, we also highlight constraints that allow for aggregate stability in spite of individual‐level change. 相似文献

It is argued in this article that threatening stimuli affect political participation levels among non‐authoritarians more than among authoritarians. Focusing on socioethnic diversity, which is known to be particularly threatening to authoritarians and to relate negatively to political participation in the general public, analyses of individual‐ and macro‐level data from 53 countries is presented which supports this thesis. Participation levels among authoritarians are largely static, regardless of a country's level of socioethnic heterogeneity, while non‐authoritarians participate considerably less in countries with relatively high levels of socioethnic heterogeneity. This suggests that authoritarians participate to a proportionately greater degree in the most diverse countries. 相似文献
