The polymorphism of nine STR loci has been studied in a sample of 598 individuals from the population of Alagoas, Northeastern Brazil. Determination of the allele frequencies as well as of several commonly used statistics in forensic and paternity testing were defined. The most polymorphic loci were TH01 and D7S317. The exact test demonstrated that the nine loci analyzed in the population have no deviation from Hardy–Weinberg equilibrium (P>0.05). 相似文献

Studies of crime at micro places have generally relied on cross‐sectional data and reported the distributions of crime statistics over short periods of time. In this paper we use official crime data to examine the distribution of crime at street segments in Seattle, Washington, over a 14‐year period. We go beyond prior research in two ways. First, we view crime trends at places over a much longer period than other studies that have examined micro places. Second, we use group‐based trajectory analysis to uncover distinctive developmental trends in our data. Our findings support the view that micro places generally have stable concentrations of crime events over time. However, we also find that a relatively small proportion of places belong to groups with steeply rising or declining crime trajectories and that these places are primarily responsible for overall city trends in crime. These findings are particularly important given the more general decline in crime rates observed in Seattle and many other American cities in the 1990s. Our study suggests that the crime drop can be understood not as a general process that occurred across the city landscape but one that was generated in a relatively small group of micro places with strong declining crime trajectories over time. 相似文献

The true impact of heat-induced changes in human bone regarding their sex estimation has not been comprehensively documented having a potentially negative impact on forensic anthropology. The objective of this paper was to evaluate how heat exposure affects sex estimation based on both morphological and metric features. The study focused in both low-to-medium intensity burns and high intensity burns. Selected sexually dimorphic features were analysed in 51 experimentally burnt skeletons from the 21st Century Identified Skeletal Collection. Bones were burnt to maximum temperatures between 450 °C and 1050 °C achieved after 75 to 257 min. Morphological methods tested in this study comprised the recommendations for hipbone features from Buikstra and Ubelaker (1994) and from Bruzek (2002). On the other hand, metric references tested here were the ones from Wasterlain (2000), Curate et al. (2016) and Gonçalves et al. (2013) focused on the humerus, femur, calcaneus and talus. Agreement was tested with Gwet’s AC1 test and was further assessed by calculating the relative amount of perfect agreements. Results demonstrated that heat-induced changes affected not only the scoring of morphological features burnt at high temperatures but also the scoring of features burnt at lower intensities. On the other hand, metric features were only considerably affected in high intensity burns, no major changes being documented for low-to-medium intensity burns. For low-to-medium intensity burns, the Bruzek and Curate et al. methods revealed a better agreement between the pre- and post-burning scores. For high intensity burns, better agreement was obtained by using the Bruzek (2002) and Gonçalves et al. (2013) methods. As expected, heat-induced warping, fracture and metric change had a major impact on the pre- and post-observations’ agreement. Contrary to what has been systematically assumed over the years, this impact is also quite substantial in bones burnt at low-to-medium burn intensities so caution is advised during the analysis of this kind of burnt skeletal material. 相似文献

High‐Performance Human Resource Practices and Employee Outcomes: The Mediating Role of Public Service Motivation 下载免费PDF全文
Ahmed Mohammed Sayed Mostafa Julian Seymour Gould‐Williams Paul Bottomley 《Public administration review》2015,75(5):747-757
This article responds to recent calls for research examining the mechanisms through which high‐performance human resource practices (HPHRPs) affect employee outcomes. Using the theoretical lens of social exchange and process theories, the authors examine one such mechanism, public service motivation, through which HPHRPs influence employees’ affective commitment and organizational citizenship behaviors in public sector organizations. A sample of professionals in the Egyptian health and higher education sectors was used to test a partial mediation model using structural equation modeling. Findings show that public service motivation partially mediated the relationship between HPHRPs and employees’ affective commitment and organizational citizenship behaviors. Similar results were achieved when the system of HPHRPs was disaggregated to consider the individual effects of five human resource practices. 相似文献

Implementing Democratic Equality in Political Parties: Organisational Consequences in the Swedish and the German Pirate Parties 下载免费PDF全文
Nicole Bolleyer Conor Little Felix‐Christopher von Nostitz 《Scandinavian political studies》2015,38(2):158-178
This article theorises and empirically assesses some important intra‐organisational implications of maximising democratic equality in political parties both between followers and members and between members and elites. They include weak member commitment, passivity of the rank‐and‐file membership and – depending on party structure – high levels of internal conflict. To substantiate the arguments, two parties that implement principles of democratic equality in their organisations are examined: the Swedish and German Pirate parties. These cases show, first, that while organisational structures implementing norms of equality allowed them to rapidly mobilise a considerable following, the same structures systematically reduced their capacity to consolidate support in the longer term – a weakness that might eventually put these parties' survival at risk. Second, they show that differences in the extent to which subnational units provide a foundation for member mobilisation helps to explain variation in the level of internal conflict experienced by these parties. 相似文献
