Extreme fragmentation can complicate the inventory of human skeletal remains. In such cases, skeletal mass can provide information regarding skeleton completeness and the minimum number of individuals. For that purpose, several references for skeletal mass can be used to establish comparisons and draw inferences regarding those parameters. However, little is known about the feasibility of establishing comparisons between inherently different materials, as is the case of curated reference skeletal collections and human remains recovered from forensic and archaeological settings. The objective of this paper was to investigate the effect of inhumation, weather and heat exposure on the skeletal mass of two different bone types. This was investigated on a sample of 30 human bone fragments (14 trabecular bones and 16 compact bones) that was experimentally buried for two years after being submitted to one of four different heat treatments (left unburned; 500?°C; 900?°C; 1000?°C). Bones were exhumed periodically to assess time-related mass variation. Skeletal mass varied substantially, decreasing and increasing in accordance to the interchanging dry and wet seasons. However, trends were not the same for the two bone types and the four temperature thresholds. The reason for this appears to be related to water absorption and to the differential heat-induced changes in bone microporosity, volume, and composition. Our results suggest that mass comparisons against published references should be performed only after the skeletal remains have been preemptively dried from exogenous water. 相似文献

The extent to which community members are willing to cooperate with the police and become involved with various community crime prevention programs depends on citizen perceptions of the police and of the community in which they reside. The purpose of the present study is to explore factors that affect support for community policing in a small rural city. Findings revealed that the majority of respondents supported community policing. Using community survey data collected from over 400 citizens in a small metropolitan area in the intermountain West, this study also explored the importance of demographic factors, community characteristics, and public perceptions and experiences with police in predicting citizens’ support for community policing. Citizen support for community-oriented policing varied somewhat by demographic factors (i.e., gender, education), and by community characteristics (i.e., disorder, social cohesion). 相似文献

The Effect of Paramilitary Protest Policing on Protestors' Trust in the Police: The Case of the “Occupy Israel” Movement 下载免费PDF全文
The use of paramilitary methods in civil policing tasks has become common in Western police agencies. Despite propositions that such methods should undermine the relationship between the police and the public, the effect of paramilitary policing on public trust in the police has not been empirically tested. In the present study, we examine this question in the context of protest policing, which has become a major concern for Western police agencies. Using a survey of 470 protesters who participated in “Occupy” protest events in Israel in 2012, we find that the perceived use of paramilitary methods has an independent and negative effect on trust, stronger than that of police effectiveness and the “neutrality” component of procedural justice. In‐depth interviews suggest that the significance of paramilitarism may be the result of a sense of alienation and criminalization it elicits among protesters who generally perceive themselves as law‐abiding citizens. 相似文献

Recent literature has recast the history of the British empire as a vast project of intervention in and reordering of colonial legal administrations. Closer inspection of local moments of legal reform, however, reveals substantial complications and contradictions in that project. This article re-considers Governor Richard Bourke's Punishment and Summary Jurisdiction Act 1832, the most celebrated legal intervention in the history of the ‘convict colony’ of New South Wales by a governor whose liberalism and humanitarianism epitomized the spirit of imperial reform agendas. The nature and objectives of Bourke's so-called Fifty Lashes Act are widely misunderstood. This article shows that while Bourke positioned his Act as a matter of legal urgency, its core aim was to render convict punishment more useful and economical. Moreover, Bourke's reforms were less innovative than is commonly assumed, being mostly required to re-assert and refine existing law that was being disregarded. Nevertheless, Bourke's reforms did address long-contested legal issues surrounding the summary jurisdiction of colonial magistrates and the local application of English transportation law. The backstory to the Act reveals the remarkably complicated and truly disordered state of the law in New South Wales, but this article also shows how the implementation of legal reform was seasoned with confusion and caution. 相似文献

This study focuses on regional entrepreneurial ecosystems and offers a complex model of start-ups, Regional Entrepreneurship and Development Index (REDI) and six domains of the entrepreneurial ecosystem (culture, formal institutions, infrastructure and amenities, IT, Melting Pot and demand). Altogether they capture the contextual features of socioeconomic, institutional and information environment in cities. To explain variations in entrepreneurship in a cross-section of 70 European cities, we utilize exploratory factor analysis and structural equation modelling for regional systems of entrepreneurship using individual perception surveys by Eurostat and the REDI. This study supports policymakers and scholars in development of new policies conducive to regional systems of innovation and entrepreneurship and serves as a basis for future research on urban entrepreneurial ecosystems. 相似文献
