Naturally preserved and embalmed bodies from archeological contexts represent a powerful source of information for forensic investigators. They allow one to ascertain pathology, cause of death, to enhance diagnostic methodology, and to improve the analysis of altered remains. We investigated the complete head and lung remnants of a 3,500‐year‐old Egyptian dignitary by radiological, microscopic, and genetic approaches. The individual, a middle‐aged male, suffered from severe periodontitis, mild atherosclerosis, and experienced cardiogenic pulmonary insufficiency with recurrent mini‐bleeds and pulmonary edema. Histology and ancient DNA analyses excluded the presence of Mycobacterium tuberculosis or of any other pathogenic species. Based on our collection of evidence, we propose that acute decompensation complicating chronic cardiac insufficiency was the likely cause of death. The underlying causes for this failure remain unknown although chronic hypertension appears to be the most likely candidate. Our finding represents the earliest reported case of chronic heart failure in ancient mummies.  相似文献

Nonprofits seek to enhance their reputation for responsible management by joining voluntary regulation mechanisms such as accountability clubs. Because external stakeholders cannot fully observe nonprofits’ compliance with club obligations, clubs incorporate mechanisms to monitor compliance and impose sanctions. Yet including monitoring and sanctioning mechanisms increases the cost of club membership for nonprofits. What factors account for the variation in the strength of monitoring and sanctioning mechanisms in voluntary accountability clubs? An analysis of 224 clubs suggests that stringent monitoring and sanctioning mechanisms are more likely in fund‐raising‐focused clubs, clubs that offer certification (as opposed to only outlining a code of conduct), and clubs with greater longevity. The macro context in which clubs function also shapes their institutional design: clubs in OECD countries and clubs with global membership are less likely to incorporate monitoring and sanctioning mechanisms than clubs in non‐OECD countries and single‐country clubs, respectively.  相似文献

In this article, we identify the unfolding unintended consequences which flow from one instance of policy layering in Australia's National Disability Insurance Scheme (NDIS). We show how use of a causal diagram, which highlights feedback loops and emergent properties, to map complex chains of causal factors can assist policy scholars and policy practitioners to understand the likely direction of change and possible responses. In the case of Australia's National Disability Insurance Scheme, our analysis suggests that the likely direction of change will work against two of the fundamental design features of the NDIS: providing participants with more choice and control, and ensuring all eligible Australians are able to access appropriate services and supports regardless of where they live. Our analysis points to the use of price regulation as the site of potential intervention because of the role it plays in subsequent feedback loops and the development of the two, unwelcome, emergent properties.  相似文献

The Racial and Religious Hatred Act 2006 has a frenetic history. It is the culmination of six attempts in Parliament in the last twelve years to make incitement to religious hatred unlawful. 1 1 Lord Lester proposed two amendments to the Criminal Justice and Public Order Bill, June 1994 and the (Lord) Bishop of Oxford moved an amendment in July 1994. Lord Avebury introduced a Religious Offences Bill in 2001. The government has tried three times: in the Anti‐Terrorism, Crime and Security Bill in 2001; in the Serious Organised Crime and Police Bill, introduced in November 2004 and (successfully) in the Racial and Religious Hatred Bill, introduced June 2005.
Each attempt has met with intense criticism. But now that the legislation is here, what may it achieve?  相似文献

"产翁制"这一风俗在世界许多地方都曾见于古文献记载或人种志.产翁制的本质是什么尽管学者们存在着分歧,但有一说影响巨大,即"产翁制"是母权制向父权制过渡的产物.事实上,这只是一个假设,母系制与父系制之间并无必然的承继关系,母系也不能必然导致母权.我国学者在古典进化论思想的影响下,在研究"产翁制"时,对古文献的理解存在着严重偏差,应该引起文化史研究者的重视.  相似文献

This study examined the self-regulatory process of moral disengagement in adolescent social bullying. Moral disengagement was assessed at the individual level, as well as within reciprocated very best friendships. At the dyadic level, this study investigated the role of friendship quality in moderating the influence of a very best friend’s moral disengagement on adolescents’ social bullying. The sample consisted of 710 mainly White students (306 males, 12–17 years). Results showed adolescents’ proneness to moral disengagement was associated with increased social bullying. Further, a very best friend’s moral disengagement was associated with higher social bullying for those who perceived positive qualities in their friendship. The findings highlight the importance of close friends in fostering adolescents’ social bullying.  相似文献

商业贿赂表现形式纷繁芜杂,对商业贿赂的治理带来诸多难题,科学界定商业贿赂的概念,分析其特点和规律,是治理商业贿赂的首要和前提。对商业贿赂的商业应当作广义的理解,不能仅仅包括商品的买卖活动;商业贿赂具有主体的广泛性、商业贿赂行为所侵犯客体的多重性、行为人主观上的故意性和行为客观上的违法性等特点。贿赂是一种以财物为媒介物的由行贿方和受贿方组成的相互关系的链条。行贿是贿赂链条的起点,起决定作用的是受贿方。商业贿赂与其他贿赂相比,具有连续性和稳定性,贿赂物数额较大,贿赂手段形式更加多样,具有更大的社会危害性。  相似文献
