Those who turn out in American primary elections are a small and unrepresentative subset of the population. Why do citizens forgo participation in nominating contests yet vote in general elections? We argue that limited contact lowers participation in primary elections. We present results from a randomized field experiment with near 150,000 letters in California’s 2014 primary. Each letter went to one of the four million Californians who had participated in recent general elections but not in primaries. We find that a single letter increased turnout by 0.5 points from a base rate of 9.3 percent. This increase is more than twice the average effect calculated in a recent meta-analysis and represents a proportional increase of 5.4 percent. Our experiment shows that registrants who typically abstain from primaries—and who are thus often ignored by campaigns—can be effectively mobilized.  相似文献

Concerns over the toxic by‐products produced by traditional ammunition have led to an increase in popularity of nontoxic ammunition. In this work, the chemical composition of six brands of nontoxic ammunition was investigated and compared to that of a road flare, which served as an environmental source with similar composition. Five rounds of each brand were fired while a further five were disassembled and the primer alone was fired. Particles collected from all samples, including the road flare, were analyzed by scanning electron microscopy with energy dispersive X‐ray analysis. Common elements among the different ammunition brands included aluminum, potassium, silicon, calcium, and strontium. Spectra were then subjected to principal components analysis in which association of the primer to the intact ammunition sample was generally possible, with distinction among brands and from the road flare sample. Further, PCA loadings plots indicated the elements responsible for the association and discrimination observed.  相似文献

Recent work on the ethics of war has struggled to simultaneously justify two central tenets of international law: the Permission to kill enemy combatants, and the Prohibition on targeting enemy noncombatants. Recently, just war theorists have turned to collectivist considerations as a way out of this problem. In this paper, I reject the argument that all and only unjust combatants are liable to be killed in virtue of their complicity in the wrongful war fought by their side, and that noncombatants are not permissible targets because they are not complicit. I then argue that just combatants have some reason to direct force against unjust combatants rather than unjust noncombatants, because they should respect the reasonable self-determining decisions of other political communities, when those communities settle on the distribution of a negative surplus of cost for which they are collectively but not individually responsible. These collectivist reasons will not fully justify the Permission and the Prohibition, but they can contribute to that justification.  相似文献

How do public administrators understand social equity toward lesbian, gay, and bisexual (LGB) individuals and communities? To better understand social equity, this study uses data on the views of public and nonprofit administrators in 33 countries in Africa on LGB people. Based on these responses, we gain a better understanding of homophobia in public administrators. Furthermore, this data helps public administrators to explore how social equity might look differently to public and nonprofit administrators in different countries. Building on this foundation, this study proposes understanding social equity from both a Micro (individual) and a Macro (cultural)-perspective. Bringing in this micro- and macro-perspective can help public administrators and researchers to discuss how individuals and organizations identify “vulnerable” populations and appropriate ways to support vulnerable groups.  相似文献

Citizens and victims perceive the criminal justice system to be protracted. Blame for lengthy delays has disproportionately fallen on detective work. To that end, these analyses explore how long it took 184 detectives to work index crimes. Data suggest that more serious crimes, cases with a known suspect, and offenses that did not result in an arrest are most likely to be investigated and worked more promptly by detectives. Detectives, however, continue to exercise a great deal of discretion in if and when cases are worked once they are assigned. These findings are discussed as they relate to police performance indicators, the allocation of departmental resources, issues of crime control, and citizen satisfaction with the police.  相似文献

The study was conducted to evaluate the effectiveness of health services training provided with different methods in combating of intimate partner violence (IPV) against women. The intervention group of the study consisted of 132 healthcare workers (HCW) and 249 HCWs in the control group. According to the result of study, training given to the intervention group was more effective in increasing the knowledge level, compared to the control group. Furthermore, comparison of the HCWs in the intervention group with the control group revealed that the attitudes towards emotional, psychological and sexual violence and justifying myths changed positively. In this scope, it can be said that intervention training was effective in terms of improving knowledge and attitude on IPV. However, it is determined that the training given to both groups was inefficient in terms of turning into behaviour.  相似文献

We present a formal model of an intelligence agency that must divide its resources between the collection and analysis of information pertaining to terror plots. The model highlights the negative consequences of queues which form when collection exceeds analytic capacity. We incorporate the response of a terrorist organization to the operating characteristics of the intelligence system it faces, and solve for equilibrium strategies for the intelligence system and terrorist organization. Our results demonstrate the importance of properly balancing resources between collection and analysis, and stand in contrast to the observed state of overcollection in US intelligence agencies.  相似文献

This study examined how youths’ gender is related to the educational expectations of urban, low-income African American youth, their parents, and their teachers. As predicted, African American boys (ages 9–16) reported lower expectations for future educational attainment than did their female counterparts. Parents and teachers also reported lower expectations for African American boys (ages 6–16) than for girls. These findings held even when controlling for academic achievement. Contrary to predictions, the magnitude of the difference in expectations for males vs. females did not increase as a function of youths’ age. In keeping with our hypotheses, parental expectations fully mediated the relation between youths’ gender and youths’ expectations. Finally, certain school-based factors (i.e., positive teacher expectations and positive youth perceptions of the school environment) appeared to protect youths’ expectations from the deleterious impact of low parental expectations.

Jury research has dealt almost exclusively with the American system wherein 6-12 laypersons decide verdicts under a unanimity or non-unanimity rule. However, most Western European countries follow the escabinado system, in which laypersons and judges together decide verdict and sentence, under a non-unanimous rule. We experimentally compared the processes and outcomes of both types of juries. Under the guise of a Student Judicial panel, seven undergraduate students in Spain comprised 10 juries, whereas five undergraduates and two fifth-year Law students comprised 10 escabinado juries. We assessed pre- and post-discussion verdict, penalty, and confidence, discussion content, and subjective reactions to the discussion and outcome. Escabinado jury deliberations were driven by the imbalance of power between trained and lay jurors. Escabinado and lay juries differed in their perception of the deliberation but not in their outcomes. Implications for the impact of cultural differences and task requirements in jury decision-making are drawn.  相似文献
