A finding in the autopsy of John Paul Jones, the American Revolutionary War naval hero, may explain his terminal illness. During his last 2 years, he had a persistent productive cough and dyspnea. Ten days before death, he developed rapidly progressive dependent edema and ascites. He died in France in 1792. His body, preserved in alcohol in a lead coffin, was, in 1905, removed to the United States. Glomerulonephritis was noted on an autopsy, performed in France, but there was no comment then or since about ventricular wall thickness being the same in both ventricles at 5–6 mm. Hypertrophy and dilatation with biventricular failure followed by tissue shrinkage during 113 years in alcohol could have resulted in these ventricular wall findings. Systemic hypertension and left ventricular failure are consistent with his respiratory symptoms complicated perhaps by pulmonary emboli, right ventricular failure with tricuspid regurgitation, peripheral congestion, and jaundice.  相似文献

This article stands at the confluence of three streams of historical social science analysis: the sociological study of power relations within the family, the regional demography of historical Europe, and the study of spatial patterning of historical family forms in Europe. It is a first exercise in the design and application of a new ‘master variable’ for cross-cultural studies of family organization and relations. This indexed composite measure, which the authors call the Index of Patriarchy, incorporates a range of variables related to familial behaviour, including nuptiality and age at marriage, living arrangements, post-marital residence, power relations within domestic groups, the position of the aged, and the sex of the offspring. The index combines all these items, with each being given equal weight in the calculation of the final score, which represents the varying degrees of sex- and age-related social inequality (‘patriarchal bias’) in different societal and familial settings. In order to explore the comparative advantages of the index, the authors use information from census and census-like microdata for 91 regions of historical Europe covering more than 700,000 individuals living in 143,000 domestic groups, from the Atlantic to the Urals. The index allows the authors to identify regions with different degrees of patriarchy within a single country, across the regions of a single country, or across and within many broader zones of historical Europe. The unprecedented patterning of the many elements of power relations and agency contained in the index generates new ways of accounting for both the geographies and the histories of family organization across the European landmass.  相似文献

In recent years, there has been a marked increase in the demand for global data on historical family systems, both in the social sciences and in the humanities. Until lately, however, scholars interested in historical global family variation had to rely on simplified and often ahistorical world-scale classifications of family systems by world geographic regions. This article communicates Mosaic to the scholarly community – one of the largest infrastructural projects in the history of historical demography and family sociology. The article provides a brief history of the project, a discussion of the main issues involved in creating the database (including sampling and representativeness), and Mosaic's data structure and coverage. In the remainder of the article, the authors provide an overview of methodological and research opportunities that the project can offer to scholars, showing how the most pertinent problems of historical family demography can be tackled in more systematic ways than previously.  相似文献

组织学生考试是高校重要的工作,但现在的考试形式大多是教师手工出题、阅卷,虽然出现了相应的答题卡形式,减少了老师一定的阅卷负担,但效率还是较低的。利用网络和数据库技术,结合目前硬件价格普遍下跌与宽带网大力建设的有利时机,基于B/S模式研究开发了试题库与在线考试系统。它运用方便、操作简单,效率较高,同时也大大减轻了教师出题、组卷和改卷等繁重的工作量。  相似文献

Biotechnology, rather than being defined as a distinct industry like steelmaking or shipbuilding, is instead a scientific knowledge base—a rapidly evolving technology—that has economically valuable applications in such diverse industries as pharmaceuticals, medical diagnostics, agriculture, bioenvironmental remediation, and chemical processing. Biotechnology has captured the imagination of ambitious scientific investigators and investors seeking high rates of return, as well as state economic development officials who hope to anchor the industry in their locality and reap the industry's economic and employment rewards. Biotech is still at an early stage of its development, and there are many competing hypotheses about its future development. Most importantly, biotechnology involves the commercialization of science resources in which the federal and state governments have made substantial investment. One key question is how to leverage this investment for future economic growth. This article explores the policy issue related to the commercialization of biotechnology, its role as an engine of economic development, and the appropriate public policy response.  相似文献

自奥巴马政府以来,特别是新冠肺炎疫情暴发后,国家安全在美国全球供应链调整中的影响日益彰显。在国家安全的视域下,美国政府调整全球供应链的逻辑依据为“国防论”与“选择性贸易保护主义”。美国的国家安全侧重国家利益与价值,全球供应链调整则诉求产品(或服务)的可替换性,二者交互作用,贸易保护主义性质的“国防论”与“选择性贸易保护主义”就成为分析美国全球供应链调整的理论分析框架。“国防论”侧重诠释具有国防意义产品(或服务)的进出口,而“选择性贸易保护主义”则分析了普通贸易实践对美国整体福利乃至国家安全的损害。美国在国家安全视域下调整全球供应链的路径依赖于软硬两种手段。一是无弹性的硬手段,表现为官僚体制、决策机制、相关法律制度与管理规范,美国全球供应链上的企业必须遵守,其具有吓阻功能。二是具有弹性的软手段,体现为国家战略以及政策说明等,其不具有强制性。基于此,这一研究有助于进一步厘清时下美国政府变动不居的对华经贸政策,构建合作与开放的中美经贸关系。  相似文献

试析对区域性国际组织运用武力的法律控制   总被引:2,自引:0,他引:2  
区域组织运用武力问题在科索沃战争后更为引人关注。在联合国宪章体系下 ,区域组织运用武力有三种类型。其中 ,集体自卫和授权型运用武力对及时有效地反对地区霸权主义、维护国际和平与安全具有重要意义。但从国际关系实践来看 ,区域组织运用武力尤其是授权型运用武力存在着较多问题 ,只有对其实行有效控制 ,才能发挥区域组织在维护国际和平与安全方面的作用  相似文献
