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

The radical political and economic reforms sweeping through former socialist countries during the last several decades have facilitated economic growth and urbanization. During this period of market reform and urbanization, citizen participation is greatly needed yet easily lost to other priorities. We employ stakeholder theory to examine whether citizen participation differs between large and small cities and between the poor and non‐poor people in Vietnam. Using data from a sample of citizens in five centrally managed cities, we found that citizens in large cities and citizens that belong to “unofficially poor” groups participate less. For policy makers, this implies that citizen participation should be of central importance in the management of current cities' expansions. In addition, the categorization of “poor households” needs to be closely monitored to minimize the risk of de facto poor households being excluded from the group.

Abstract

Deinstitutionalisation movements of the mid-1900s led to changes in policy and practice in the management of people with special needs (defined for this article as people with severe and persistent mental illness, intellectual disabilities and high levels of personality factors that interfere with treatment participation). Although the majority of clients with special needs receive care in community settings and interact more with family, friends and others in the community, some such clients require more rigorous case management. For clients who have offended, especially sexually, community-based services are scarce, and concerns regarding reoffence potential often supersede traditional understandings of diminished capacity. Recent reports suggest that jails and prisons have replaced hospitals as the institutions-of-choice for clients with special needs who engage in inappropriate conduct. This paper examines policies and practices regarding community risk management of people with special needs who have sexually offended. Vignettes are provided to illustrate how some clients and agencies have been affected, and suggestions are made to ensure best practices in risk management and public safety.  相似文献

Most studies that have focused on female serial killers (FSKs), although informative, have examined limited sample sizes. We consulted mass media reports of demographics, motives, methods, mental health, and victim characteristics of 64 FSKs who committed their crimes in the US from 1821 to 2008. Consistent with other studies, our data showed that FSKs were typically White, educated, have been married, and held a caregiving role (e.g. mother, health care worker). Nearly 40% of FSKs in this sample experienced some form of mental illness. Their most common motive for murder was financial gain, and their most common method of killing was poisoning. FSKs knew all or most of their victims, and most were related to their victims. In all cases, FSKs targeted at least one victim who was a child, elderly, or infirm – those who had little chance of fighting back. We interpret these killers’ behaviors from clinical and evolutionary angles.  相似文献
