Elevators are mechanical transportation devices used to move vertically between different levels of a building. When first developed, elevators lacked the safety features. When safety mechanisms were developed, elevators became a common feature of multistory buildings. Despite their well-regarded safety record, elevators are not without the potential for danger of injury or death. Persons at-risk for elevator-related death include maintenance and construction workers, other employees, and those who are prone to risky behavior. Deaths may be related to asphyxia, blunt force, avulsion injuries, and various forms of environmental trauma. In this review, we report on 48 elevator-related deaths that occurred in nine different medicolegal death investigation jurisdictions within the United States over an approximately 30-year period. The data represents a cross-section of the different types of elevator-related deaths that may be encountered. The review also presents an overview of preventive strategies for the purpose of avoiding future elevator-related fatalities. 相似文献

The special issue ‘Fragile States: A Political Concept’ investigates the emergence, dissemination and reception of the notion of ‘state fragility’. It analyses the process of conceptualisation, examining how the ‘fragile states’ concept was framed by policy makers to describe reality in accordance with their priorities in the fields of development and security. The contributors to the issue investigate the instrumental use of the ‘state fragility’ label in the legitimisation of Western policy interventions in countries facing violence and profound poverty. They also emphasise the agency of actors ‘on the receiving end’, describing how the elites and governments in so-called ‘fragile states’ have incorporated and reinterpreted the concept to fit their own political agendas. A first set of articles examines the role played by the World Bank, the oecd, the European Union and the g7+ coalition of ‘fragile states’ in the transnational diffusion of the concept, which is understood as a critical element in the new discourse on international aid and security. A second set of papers employs three case studies (Sudan, Indonesia and Uganda) to explore the processes of appropriation, reinterpretation and the strategic use of the ‘fragile state’ concept. 相似文献

Persson and Tabellini (The Economic Effects of Constitutions, The MIT Press, Cambridge, 2003) show that presidential regimes and majoritarian election systems have important economic effects. Here, the number of countries is expanded and more recent data is used. In replicating and extending their analyses, we find that the effect of presidential regimes vanishes almost entirely. With regard to electoral systems, the original results are largely confirmed: majoritarian (as opposed to proportional) electoral systems lead to lower government expenditure, lower levels of rent seeking but also lower output per worker. The institutional details, such as the proportion of candidates that are not elected on party lists and district size, are particularly important. 相似文献

AIM:To investigate possible differences in dendritic cells(DC)within intestinal tissue of mice before and after induction of colitis. METHODS:Mucosal DC derived from intestinal tissue,as well as from mesenteric lymph nodes and spleen,were analyzed by fluorescence activated cell sorting(FACS) analysis.Supernatants of these cells were analyzed for secretion of different pro-and anti-inflammatory cytokines. Immunohistochemistry and immunofluorescence were performed on cryosections of mucosal tissue derived fro... 相似文献

Regional conflicts are becoming increasingly complex due to the involvement of an ever more numerous and interconnected set of actors. Previous research has focused on regional conflict systems and has generated theoretical approaches such as the regional security complex paradigm. However, when complex, multifaceted, seemingly contradictory webs of relationships are spun in a region, new tools are needed to analyze and evaluate them. Drawing on previous regional conflict models, we propose a negotiation-oriented framework of regional conflict analysis that explores the type and intensity of relationships between state and nonstate actors in a conflict system. We offer a seven-step scale of relationships (ranging from ally to active armed opponent) that represents a novel contribution to the methodological efforts to analyze relationships in conflict systems. This framework brings to light the relational imbalance of the MENA region and has the potential to contextualize for negotiators and mediators the complex system of conflicts within, and possibly outside, the region. 相似文献

International relations scholars have traditionally focused on state-centered accounts of international legal norm development between nations while sociolegal scholars have focused on Weberian notions of occupational authority. This study advances a constructivist sociolegal approach emphasizing activist action as playing a unique role in shaping international norms. Specifically, this study investigates labor activists' intervention in U.S. bilateral and multilateral free trade agreements (FTAs) to examine why labor activists chose to initiate FTA disputes as a social movement tactic and how strategic interaction with international legal systems has helped them institutionalize and proliferate the International Labor Organizations' core labor standards. Through semi-structured interviews with legal, union, and government officials, alongside a content analysis of cases filed under the U.S. FTA system, this study shows the role activists played in advancing “globalized” standards in international law. This study finds that activists spread norms through a gradual mechanism of accretion, which focuses on the creation of standards and international legal standing over the individual outcomes of any given case. 相似文献

Around 1900, various crimes were still caused by criminal superstition. Criminologists like Hans Gross, Albert Hellwig and August L?wenstimm were engaged in the exploration of this topic aiming at the complete explanation of criminal behaviour linked to superstition. Crimes against pregnant women and infants are particularly good examples to illustrate the problems arising from crimes motivated by superstition. When assessing superstition under scientific and legal aspects, the criminologists applied different approaches, although positivistic rationalization was the most common tendency. In the forensic and legal evaluation of crimes related to superstition the problematical questions were whether the perpetrator was criminally responsible and how the offence was to be legally qualified. In many cases, criminals motivated by superstition were treated with more lenience. 相似文献

The commercialisation of therapeutic products containing regenerative human tissue is regulated by the common law, statute and ethical guidelines in Australia and England, Wales and Northern Ireland. This article examines the regulatory regimes in these jurisdictions and considers whether reform is required to both support scientific research and ensure conformity with modern social views on medical research and the use of human tissue. The authors consider the crucial role of informed consent in striking the balance between the interests of researchers and the interests of the public. 相似文献
