We study basic information treatments regarding sexual orientation using randomized experiments in three countries with strong and widespread anti-gay attitudes: Serbia, Turkey, and Ukraine. Participants who received information about the economic costs to society of sexual orientation discrimination were significantly more likely than those in a control group to support equal employment opportunities based on sexual orientation. Information that the World Health Organization (WHO) does not regard homosexuality as a mental illness increased social acceptance of sexual minorities, but only for those who reported trust in the WHO. Our results have important implications for policymakers aiming to expand the rights of lesbian, gay, and bisexual people worldwide.  相似文献

This study clarifies three important issues regarding situational or opportunity theories of victimization: (1) whether engaging in risk activities triggers violent assault during specific, often fleeting moments, (2) how environmental settings along individuals’ daily paths affect their risk of violent assault, and (3) whether situational triggers have differential effects on violent assault during the day versus night. Using an innovative GIS-assisted interview technique, 298 young male violent assault victims in Philadelphia, PA described their activity paths over the course of the day of being assaulted. Case-crossover analyses compared each subject’s exposure status at the time of assault with his own statuses earlier in the day (stratified by daytime and nighttime). Being at an outdoor/public space, conducting unstructured activities, and absence of guardians increase the likelihood of violent victimization at a fine spatial–temporal scale at both daytime and nighttime. Yet, the presence of friends and environmental characteristics have differential effects on violent victimization at daytime versus nighttime. Moreover, individual risk activities appeared to exhibit better predictive performance than did environmental characteristics in our space–time situational analyses. This study demonstrates the value of documenting how individuals navigate their daily activity space, and ultimately advances our understanding of youth violence from a real-time, real-life standpoint.  相似文献

School shooting tragedies and the juvenile justice system’s movement toward a retributive and punitive framework gravely impacted how primary and secondary school students, disproportionately urban districts, used security measures to lock down campuses and build “fortress-like” schools. This iteration of control on school campuses emerged in tandem with the most recent generation’s zero tolerance approach to student violence and problems; a policy widely regarded as ineffective in urban, suburban, and rural districts. As school shootings continue to impact state legislative action and public reactions to school management, this paper takes a critical approach to school security policies and reviews the evidence on the risk for school violence and how to move away from student control approaches that do not improve school safety. Instead, the incorporation of prosocial education and school engagement efforts finds that school and student safety is improved. These, and related approaches to student body management, decreases campus violence and may also minimize the risk of some school shootings - as rare as these tragic incidents are across the nation’s schools. The interplay of schools, students, and the juvenile and family courts is ongoing. Knowing how school districts can best approach their campus environments, safety, and learning is important for school social workers and court personnel because of how often these systems work, or do not work, together.  相似文献

The relationship between votes and seats in the legislature lies at the heart of democratic governance. However, there has been little previous work on the downstream effects of partisan gerrymandering on the health of political parties. In this study, we conduct a comprehensive examination of the impact of partisan advantage in the districting process on an array of downstream outcomes. We find that districting bias impedes numerous party functions at both the congressional and state house levels. Candidates are less likely to contest districts when their party is disadvantaged by a districting plan. Candidates that do choose to run are more likely to have weak resumes. Donors are less willing to contribute money. And ordinary voters are less apt to support the targeted party. These results suggest that gerrymandering has long-term effects on the health of the democratic process beyond simply costing or gaining parties seats in the legislature.  相似文献

Pilot and demonstration (P&D) projects are commonly deployed to catalyze early adoption of technology but are poorly understood in terms of mechanism and impact. We conceptually distinguish unique functions of pilots and demonstrations, then examine whether they accelerate adoption in the case of green building technology. To identify effects on adoption, we develop a difference-in-difference-in-differences strategy, exploiting variation in timing, location, and technologies of green building P&Ds. Results indicate local quarterly green building adoption rates double following completion of a P&D project. Further analyses examine mechanisms driving this effect. The results suggest green building demonstration projects create learning externalities, proliferating technology diffusion in local markets and through building owner networks. Together, these results suggest that investments in P&D projects by public and private actors can lower costs for subsequent adoption.  相似文献

The political discourse is characterised by two opposing ideals of hard and soft Brexit. In this article, we present evidence of attitudinal types that map neatly onto these archetypal views. The hard Brexit view is defined by issues that eurosceptics prioritise, most prominently sovereignty. By contrast, europhiles prioritise cooperation with Europe in terms of scientific collaboration and market access. However, attitudinal types are not either/or in the minds of the British public, and many prioritise all or none of the issues. Further, the two opposing positions together account for 37 per cent of the public's view. That is, just over one‐third differentiate between the salient issues in ways congruent with political ideals. National identity plays a particular role in the sociodemographic profiles of these attitude types. Older people have a strong stance in any direction (sovereignty, cooperation, or both), but national identity is linked to differentiated positions (sovereignty only or cooperation only).  相似文献

Data from 117 countries over the period 2006 to 2011 are used to estimate a macroeconomic cross-country system of equations that examines the association between terrorism, self-reported life satisfaction, and national income. Results indicate that terrorism is negatively associated with life satisfaction, whereas no such association is found between terrorism and real GDP per worker. Stark contrasts are found, however, between OECD and non-OECD members. In all, our results suggest that the social costs of terrorism are potentially much higher than the economic costs, and measuring only the conventional economic costs of terrorism significantly underestimates the true costs.  相似文献
