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 international diffusion of electoral systems: The spread of mechanisms tempering proportional representation across Europe 下载免费PDF全文
There is an assumption in much of the electoral engineering literature that domestic episodes of electoral system choice occur in a vacuum, isolated from international influences. Yet this assumption remains largely untested, despite the comparative focus of much of that literature. This article focuses on part of this gap by considering two electoral mechanisms that seek to limit party system fragmentation under proportional representation – low district magnitudes and high electoral thresholds – and shows that the mechanisms have spread across many European countries during the post‐1945 period. Analyses reveal that national legislators are more likely to adopt one of these electoral mechanisms when a large number of peer countries have made similar choices within the last two or three years. This effect is robust to various model specifications and to the inclusion of multiple controls. The article also offers some qualitative evidence from case studies and parliamentary debates. 相似文献

The aim of this study was to analyze the differences between the handwritings of schizophrenia patients and healthy subjects in addition to the changes that occurred in schizophrenia patients' handwriting in response to the treatment. The test subjects were 29 schizophrenia patients and 29 healthy individuals with the same age, gender, and dominant hand. The changes in the handwritings were examined according to 14 different parameters. On the day of admittance, the percentage of extra letters was 16.7%, and after 7–10 days of hospitalization, it rose to 33.3%. The percentage of skipped words decreased from 29.2% to 16.7% after 7–10 days of hospitalization, and to 10% after 3 weeks. The letters written by schizophrenia patients are significantly larger in height and width compared to the control group. The schizophrenia patients showed a higher incidence of crossed-out letters, adding extra words, missing punctuation as well as missing words. 相似文献

In this article my purpose is to go thoroughly into the ideas expressed by economists regarding the legitimacy of absolute property rights. I visit the Lockian argument taken up by Murray Rothbard (1.1) and the principle of the finder keeper clarified by Israel Kizner (1.2). I argue that it is impossible to legitimate either the property of the finder keeper or the property of oneself if man does not think of himself as an individual. Indeed individualism becomes the cultural prerequisite required to acknowledge the rights of the finder keeper and the goods obtained through labour. Here, Hayek's complex individualism is akin to the hypothesis of the social animal of Benjamin Constant and the work of Gabriel Tarde on the transformation of law. The individual is both an effect and a cause of property rights. 相似文献

This article uses a case-study methodology to explore the impact of problematic relationships on the initiation of consensus-building efforts. The article notes that poor relations hinder the initiation process, while the expectation of benefits likely to result from the effort fosters the involvement of parties. The association between poor relations and expected benefits is explored with a focus on the appeal of collaboration. Strategies are then outlined to help facilitators to deal with problematic relationships by mitigating poor relations, highlighting incentives for participation, and building on the appeal of collaboration. Facilitators can use these strategies to increase their chances of success in initiating consensus-building efforts. 相似文献

In its final months the outgoing Thompson Liberal Ministry was largely pre-occupied with the implementation of its New Directions strategy. It introduced a public service bill in December to bring about greater effectiveness in the public service and ensure that its policy priorities were understood, thus complementing the Effectiveness Review Committee already set up, and it began a review of the three central coordinating agencies, the Public Service Board, the Treasury and the Department of the Premier, with an independent American consultant. The thrust of these three measures was to advise the government on proposals to set up new departments, relocate personnel and manpower resources, to set up programs for effectiveness reviews, and to bring forward amendments to the Public Service Act of 1974 which had followed Sir Henry Bland's inquiry in the early 1970s. These were intended to give the Public Service Board extended powers to allow it to conduct effectiveness reviews into statutory authorities, to extend Board employment powers to such authorities and to bring them into the public service framework, ensuring a more cohesive and less fragmented State public service. Senior staff could now be employed on term appointments, with performance-oriented objectives, giving greater flexibility at the top. And finally, the Board was to have power to become involved in specific industrial issues at the departmental level, sharpening its current generalized industrial powers. 相似文献
