In this study we revisit the question of black representation on city councils and school boards using a novel substantive and methodological approach and longitudinal data for a sample of over 300 boards and councils. Conceptualizing black representation as a two-stage process, we fit Mullahy's hurdle Poisson models to explain whether and to what extent blacks achieve representation in local legislatures. We find that while the size of the black population and electoral arrangements matter more than ever, especially for overcoming the representational hurdle, the extent to which the black population is concentrated is also strongly associated with black council representation. Further, whereas black resources and opportunities to build "rainbow" coalitions with Latinos or liberal whites are marginally if at all related to black legislative representation, we find that legislative size is an underappreciated mechanism by which to increase representation, particularly in at-large systems, and is perhaps the best predictor of moving towards additional representation.  相似文献

Traditional studies of minority incorporation focus on the redistribution of public resources that purportedly follows black gains in representation. The present study departs from this approach by focusing on the attitudinal effects of black leadership. Two research questions guide this study: To what extent do blacks' assessments of neighborhood services and conditions stem from black representation in local executive and legislative offices? Are these attitudinal effects rooted in policy and service delivery outcomes? Employing survey data from 3,000 blacks embedded in 52 cities and 53 school districts, this study reveals that blacks report higher levels of satisfaction with their neighborhood conditions, police services, and public schools when represented by blacks in city hall and on school boards and that these evaluations are most positive when improvements in local services are conspicuous. Overall, these findings extend conventional conceptualizations of substantive benefits and challenge more pessimistic accounts regarding the effects of black representation in local politics.  相似文献

This research examined the impact of eyewitness identification decisions on student-investigators. Undergraduates played the role of police investigators and interviewed student-witnesses who had been shown either a good or poor view of the perpetrator in a videotaped crime. Based on information obtained from the witness, student-investigators then chose a suspect from a database containing information about potential suspects and rated the probability that their suspect was the culprit. Investigators then administered a photo lineup to witnesses, and re-rated the probability that their suspect was guilty. Student-investigators were highly influenced by eyewitness identification decisions, typically overestimating the information gained from the identification decision (except under conditions that led witnesses to be very accurate), and were generally unable to differentiate between accurate and inaccurate witnesses.

This paper examines the relation between parental migration and children’s health in Ghana (N = 2760) and Nigeria (N = 2168) and considers four dimensions of parental migration: the type of separation, parental migration and the caregiver, stability of care arrangements, and the availability of remittances. By employing an ordered scale of children’s self-rated health, we found that children with international migrant parents who are divorced/separated are less likely than children in non-migrant families to have good health. The magnitude of the effects are higher in Nigeria, attesting for a greater vulnerability of Nigerian children in divorced migrant families. Among children with parents living abroad who are stably married, specific dimensions of children’s transnational life are associated with negative health, while others are not. This study highlights the sensitivity of results to the context of parent-child separation and to the transnational dimension being measured.  相似文献

Motor vehicle driver fatalities (≥18 years) from the files at Forensic Science South Australia were reviewed from January 2008 to December 2018 for cases in which either positive blood sample for methamphetamine (MA) or an illegal blood alcohol concentration (BAC) >0.05g/100 ml were found. Three hundred driver deaths were found with MA detected in 28 cases (age range 21–62 years; ave. 37.8 years; M:F 23:5). Hundred and fifteen cases with a BAC > 0.05 g/100 ml were identified (age range 18–67 years; ave 35.7 years; M:F 95:20). No change was found in numbers of MA cases, although alcohol cases showed a significant decline (p < 0.001). Drunk driving-related fatal crashes tended to occur in the evening (5 p.m. to 11 p.m.), while MA-related fatal crashes had a longer peak extending from late evening until late morning (11 p.m. to 8 a.m.). This study has demonstrated that while roadside breath testing, legislative changes, and increased monitoring have resulted in reduced levels of drunk driving, similar safety countermeasures have had negligible effects on MA use in drivers. Continued monitoring of MA use by drivers will, therefore, be necessary to assess the possible effects, or not, of new countermeasures.  相似文献
