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

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.

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

This paper, which uses data on National Park visitors between 1979 and 1998 and every county in the United States, is the
most exhaustive examination to date of how visitors affect crime. After controlling for many other factors that influence
crime, the county-level regressions consistently indicate that national park visitors have no effect on either property or
violent crime. These results are true for a variety of different measures of park visitors, for different empirical specifications,
and for different regression formats. We therefore conclude that some visitor types have no impact on crime. This conclusion
sheds light on the empirical issue of whether only some types of recreational visitors increase crime or whether visitors,
regardless of their type, necessarily increase crime. 相似文献

The current evidence base for in-home services in child welfare is limited, with insufficient research on the use of in-home services among ethnically diverse populations. This article describes a case study examining the use of a community-defined practice and evidence approach to develop tribally based in-home service models with Alaska Native communities. The models were co-created by tribal elders, community members, and service providers, with technical assistance provided by the Western and Pacific Child Welfare Implementation Center (WPIC). Research findings suggest that this is an effective approach to developing culturally appropriate child welfare practices while also building local support and ownership. 相似文献
