DNA profiling evidence presented in court should be accompanied by a reliable estimate of its evidential weight. In calculating such statistics, allele frequencies from commonly employed autosomal microsatellite loci are required. These allele frequencies should be collected at a level that appropriately represents the genetic diversity that exists in the population. Typically this occurs at broadly defined bio-geographic categories, such as Caucasian or Asian. Datasets are commonly administered at the jurisdictional level. This paper focuses on Australian jurisdictions and assesses whether this current practice is appropriate for Aboriginal Australian and Caucasian populations alike. In keeping with other studies we observe negligible differences between Caucasian populations within Australia when segregated geographically. However segregation of Aboriginal Australian population data along contemporary State and Territory lines appears to mask the diversity that exists within this subpopulation. For this reason datasets collated along more traditional lines may be more appropriate, particularly to distinguish the most genetically differentiated populations residing in the north of the continent. 相似文献

The municipal zoning process in the United States has come under increasing attack as a tool to create and maintain suburban socioeconomic homogeneity by mandating sprawl‐producing single‐family detached houses at the expense of less costly townhouses, apartments, and mobile homes. Beginning in the 1970s, the Supreme Courts of the neighboring states of Pennsylvania and New Jersey addressed municipal exclusionary zoning in different ways: Pennsylvania empowered residential developers to compel municipalities practicing exclusionary zoning to authorize market‐rate development of all types of housing, while developer empowerment in New Jersey was conditioned upon inclusion of low‐ and moderate‐income units. Using aerial survey and housing census data over a 20‐year period, this article finds that outcomes by housing type over a 20‐year period in Pennsylvania municipalities around Philadelphia were more diverse than those in adjacent New Jersey municipalities. © 2004 by the Association for Public Policy Analysis and Management. 相似文献

Leading police scholars and practitioners were asked to reflect on the most urgent issues that need to be addressed on the topic of use of force. Four themes emerged from their contributions: use of force and de-escalation training needs to improve and be evaluated; new ways of conceptualizing use of force encounters and better use of force response models need to be developed; the inequitable application of force, and how to remediate biases, needs to be more fully understood; and misconceptions about police use of force need to be identified and corrected. The highlighted topics serve as an agenda for future research. Such research should provide greater insight into when, where, and why force is used by police officers, and how it can be applied appropriately. If implemented, the practical recommendations included in the contributions should have a positive impact on police performance, public trust and confidence in the police, and citizen and officer safety. 相似文献

When multiple taxing jurisdictions overlap and fail to account for one another’s actions, they over-tax the common base. This is a prediction of the anticommons model, in which numerous parties have authority to exclude others from using a resource. This model further predicts that when governments over-tax the base, private parties will underutilize the resource, and underutilization will be greater as the number of parties with exclusion rights rises. We test these predictions by studying cell phone taxation and local option tax authority, which allows some cities, counties, and special-purpose districts to levy taxes on cell phone use. Consistent with theory, we find that the tax rate on cell phone service is higher when local governments have the option to tax. Further, the percentage of households owning cell phones is lower when there is the local option to tax, and ownership rates fall with the number of taxes levied. 相似文献
