The forensic diagnosis of cardiac contusion has hitherto been based mainly on anamnesis, concomitant thoracic injuries and the detection of macroscopic changes to the heart. Parallel histological and serological investigations of the heart-specific troponins have been conducted with varying results. This paper aims to show whether heart-specific troponins are suitable as a means of securing the diagnosis in proven cases of cardiac contusion and of determining which of the three heart-specific troponins cTnT, cTnI and cTnC are most significant in serology and histology for postmortem diagnosis.In the study, 25 cases of known cardiac contusion and 11 controls without vital myocardial trauma taken from autopsy material were prospectively investigated. Investigation of the venous serum revealed significant differences in the concentrations of the case and control groups for troponin T (mean value 5.5056 versus 0.4982; p = 0.014), for troponin C (mean value 263.9280 versus 68.5640; p = 0.001) and for troponin I (mean value 1404.0560 versus 36.1650; p = 0.003). In histology there are also significantly different depletions between the groups investigated (cTnT: p = 0.002; cTnC: p = 0.003; cTnI: p < 0.001) taking into account the autolysis time. 相似文献

This article investigates the hypothesis that 19th-century working class families in Leuven, Belgium, were controlling their fertility by means of birth spacing for household economic reasons. Detailed life-course data were collected in order to construct, on one hand, a set of covariates that represent the influences of natural fertility on birth intervals and, on the other, a number of family variables that represent the hypothetical, household economic motivation to space births. The findings strongly suggest that birth intervals were not merely a function of natural fertility differences and that family strategic spacing behavior also played a role. 相似文献

This study examines how programs sponsored through the National Institute of Standards and Technology's Manufacturing Extension
Partnership (MEP) have influenced the organization and delivery of industrial modernization services to small and medium-sized
manufacturers in regions in the United States. The study found that increased service coordination has occurred and that this,
in turn, has mostly improved the quality and comprehensiveness of assistance delivered to firms. But there are also some costs
and drawbacks associated with multi-partner service delivery approaches. The study identifies and examines best practices
that can help MEP centers increase the effectiveness of service coordination.
This paper draws upon research supported by the U.S. Department of Commerce, National Institute of Standards and Technology
under award 50SBNBC8305. The views expressed are the authors' and do not necessarily reflect those of the research sponsor. 相似文献

AbstractDecentralization reforms introduced to Africa have not always delivered the intended outcomes. Through interaction with the broader historical, political, social and economic context, reforms seem to have engendered political consequences beyond decentralization itself. Most of the literature on decentralization and development emphasizes questions of institutional design and policy, but here we expand the focus of analysis and incorporate the harder-to-pin-down political patterns marking the workings of decentralization in Africa. Through the case-studies of Ghana, Senegal, Zimbabwe, Namibia, Ethiopia and Uganda we seek to connect the debates on development with the scholarly literatures on comparative federalism, comparative decentralization and local democracy. The conclusion that emerges is that no magic formula which can turn countries into peaceful, stable and prosperous democracies overnight exists. And, importing formal institutions without regard to the local historical, political, social and economic context risks leaving us with elegant but dysfunctional iron houses in the tropical heat. 相似文献

In 2013, the Laos Ministry of Education and Sports (MoES) commissioned a mid-term review of the Education Sector Development Plan 2011–2015 (ESDP, Lao People's Democratic Republic, Ministry of Education and Sports 2010). Plan International, a United Nations Girls Education Initiative partner, worked with MoES to lead a gender audit for the mid-term review. The gender audit strengthened the mid-term review and contributed to the design of the new ESDP. A MoES gender and inclusion working group was established, providing an institutional structure to support focused policy dialogue and address recommendations. This note recommends the inclusion of gender audits within mid-term reviews and final evaluations of sectoral plans to ensure that investments adequately address gender equality. 相似文献

This article addresses the vagueness, and the interpretative challenges associated with, international investment agreements (IIAs) and develops a new normative framework for interpreting these treaties. It focuses on the historical embedding of investment protection as a means of facilitating economic development as well as upon its synthetic public law nature. The analysis shows that a teleological approach to interpretation imposes boundaries on the meaning of substantive IIA provisions. The article then elaborates how the transnational dimension of IIAs provides a benchmark, which is the level of protection offered to economic actors against interference by the state in countries with the highest rule of law standards. The article then shows how the resulting challenges of comparative public law could be addressed through the methodology of re‐ and pre‐statement of transnational uniform ‘principles’: sophisticated and detailed rules striking the proper balance between private economic interests and the public regulatory interest, so as to provide more legal certainty for both investors and host states. 相似文献
