This study examines views about police legitimacy and competence in neighbourhoods over time. The study compares theories about police legitimacy, the cooperation hypothesis, and the collective security hypothesis to predict violence. Findings suggest that when police legitimacy is deficient in neighbourhoods, a culture supportive of violence to resolve disputes may develop. Results show the importance of police competence to suppress violence and build collective efficacy. Finally, police are more successful in neighbourhoods that are collectively efficacious. The cooperation hypothesis is fully supported, but the collective security hypothesis and LaFree’s legitimacy theory receive partial support. Findings underscore the merit of examining neighbourhood consequences of police legitimacy, including how institutions, like police, can impact neighbourhood socialisation processes and are impacted by them.  相似文献

As drug overdose deaths across the United States continue to rise, there is increasing interest in field testing of illicit substances. This work discusses a paper-based analytical device (idPAD) that can run a library of 12 colorimetric tests at the same time, each detecting different chemical functional groups and materials found in illicit drugs, distractor substances, and cutting agents. The idPAD requires no electricity, costs less than $2 USD, and requires minimal training to operate. The results of the 12 tests form a color barcode which is “read” by comparison to standard images. The accuracy of the idPAD was assessed using samples of heroin, cocaine HCl, crack, and methamphetamine at concentrations of 25%–100% in a lactose matrix, as well as pure lactose. Based on 840 “reads” by three different users, the idPAD showed 95% sensitivity and 100% specificity for detecting these drugs; the most common error was mistaking cocaine HCl for crack or crack for cocaine HCl. In a second step, samples of heroin, cocaine, and methamphetamine (n = 30) and distractor substances (pharmaceuticals, cutting agents, and other illicit drugs, n = 64) were tested by two readers, yielding a sensitivity of 100% and specificity of 97%. Targeted substances were detected reliably at 55–180 μg/lane, and the idPAD was found to be stable for at least 3 months when stored at room temperature. The library approach used in the idPAD may provide the accuracy and robustness necessary for a presumptive field drug test.  相似文献

Expressive suppression is regarded as a generally ineffective emotion regulation strategy and appears to be associated with the development of depressive symptoms among adolescents. However, the mechanisms linking suppression to depressive symptoms are not well understood. The main aim of this study was to examine two potential mediators of the prospective relationship from depressive symptoms to expressive suppression among adolescents: parental support and peer victimization. Structural equation modelling was used to construct a three-wave cross-lagged model (n?=?2,051 adolescents, 48.5?% female, at baseline; 1,465 with data at all three time points) with all possible longitudinal linkages. Depressive symptoms preceded decreases in perceived parental support 1?year later. Decreases in parental support mediated the relationship between depressive symptoms and increases in expressive suppression over a 2-year period. Multi-group analyses show that the mediation model tested was significant for girls, but not for boys. No evidence for other mediating models was found. Although initial suppression preceded increases in depressive symptoms 1?year later, we did not find any evidence for the reversed link from suppression to depressive symptoms. Clear evidence for a reciprocal relationship between depressive symptoms and parental support was found. However, only limited and inconsistent support was found for a reciprocal relationship between depressive symptoms and peer victimization. Finally, although some evidence for a unidirectional relationship from parental support to increases in suppression was found, no significant prospective relationship was found between peer victimization and suppression. The implications of our clear results for parental support, and mostly lacking results for peer victimization, are discussed.  相似文献

ABSTRACT

Acts of cyberterrorism represent potential, significant negative effects to property, infrastructure systems, security, and an overall way of life. These disruptions garner significant attention from government and the public. Managers concerned by threats of cyberterrorism should understand the components that enhance organizational competence so that doubt and fear do not overtake organizational members when faced with such extreme events. Although organizational competence is important in everyday organizational behaviors, the presence of confidence in organizational abilities is especially critical when operating in the midst of the ambiguity and destructive disruptions associated with cyberterrorist threats. We empirically assess three factors associated with competence for organizations facing simulated cyberterror attacks. Our results support the relationship between two of these factors—organizational identification and deference to expertise—with organizational competence. These findings contribute to research concerning the antecedents critical to organizational competence and also add to the growing research on cyberterrorism.  相似文献

Abstract: Governments in Canada have recently been exploring new accountability measures within intergovernmental relations. Public reporting has become the preferred mechanism in a range of policy areas, including early learning and child-care, and the authors assess its effectiveness as an accountability measure. The article is based on their experience with a community capacity-building project that considers the relationship between the public policy, funding and accountability mechanisms under the federal/provincial/territorial agreements related to child-care. The authors argue that in its current form, public reporting has not lived up to its promise of accountability to citizens. This evaluation is based on the standards that governments have set for themselves under the federal/provincial/territorial agreements, as well as guidelines set by the Public Sector Accounting Board, an independent body that develops accounting standards over time through consultation with governments.  相似文献

Former South African Prime Minister Jan Smuts’s 1930 European and North American tour included a series of interactions with diasporic African and African American activists and intelligentsia. Among Smuts’s many remarks stands a particular speech he delivered in New York City, when he called Africans “the most patient of all animals, next to the ass.” Naturally, this and other comments touched off a firestorm of controversy surrounding Smuts, his visit, and segregationist South Africa’s laws. Utilizing news coverage, correspondence, and recollections of the trip, this article uses his visit as a lens into both African American relations with Africa and white American foundation work toward the continent and, especially, South Africa. It argues that the 1930 visit represents an early example of black internationalism and solidarity, reflecting a shift from sociocultural connections between Africa and the diaspora to creating political movements on behalf of African people. To contextualize this visit, we assess events surrounding a meeting that the Phelps-Stokes Fund organized for Smuts at Howard University, using this as a lens into the two disparate, yet interlocked, communities.  相似文献

Psychopathic traits are associated with violent, aggressive behaviors and recidivism in adulthood. To increase positive treatment outcomes, it is arguably beneficial to identify and treat psychopathy as early as possible. Furthermore, because research shows that the effectiveness of behavior modification is likely to be affected by the social information-processing patterns of aggressive children, it is important to understand the relationship between conduct-disordered traits and social cognitions. The results of this study showed that callous/unemotional traits in a community-based sample of behavior-disordered youth (57 male, 19 female; 10-19 years of age; 63% African American) significantly predicted values in obtaining a tangible reward and getting into trouble or being punished. However, callous/unemotional traits, impulsivity/conduct problems, and narcissism failed to predict positive expectations regarding receiving a tangible reward, reducing aversive treatment, and demonstration of dominance. Implications for these results are presented.  相似文献
