A 56-year-old woman died suddenly and unexpectedly of a cardiac tamponade due to spontaneous rupture of the right ventricle. The cardiac rupture occurred on the basis of clinically unsuspected cardiac sarcoidosis. Sudden death due to spontaneous rupture of a cardiac chamber is a previously unreported complication of sarcoidosis.  相似文献

An important component of incumbent support is the reward/punishment calculus of economic voting. Previous work has shown that "clarity of responsibility" within the central state government conditions national economic effects on incumbent vote choice: where clarity is high (low), economic effects are greater (less). This article advances the "clarity of responsibility" argument by considering the effect of multilevel governance on economic voting. In institutional contexts of multilevel governance, the process of correctly assigning responsibility for economic outcomes can be difficult. This article tests the proposition that multilevel governance mutes effects of national economic conditions by undermining responsibility linkages to the national government. Individual-level data from the Comparative Study of Electoral Systems Module 1 are used to test this proposition. Results demonstrate that economic voting is weakest in countries where multilevel governance is most prominent. Findings are discussed in light of the contribution to the economic voting literature and the potential implications of multilevel governance.  相似文献

Medical examiners and coroners (ME/C) in the United States hold statutory responsibility to identify deceased individuals who fall under their jurisdiction. The computer‐assisted decedent identification (CADI) project was designed to modify software used in diagnosis and treatment of spinal injuries into a mathematically validated tool for ME/C identification of fleshed decedents. CADI software analyzes the shapes of targeted vertebral bodies imaged in an array of standard radiographs and quantifies the likelihood that any two of the radiographs contain matching vertebral bodies. Six validation tests measured the repeatability, reliability, and sensitivity of the method, and the effects of age, sex, and number of radiographs in array composition. CADI returned a 92–100% success rate in identifying the true matching pair of vertebrae within arrays of five to 30 radiographs. Further development of CADI is expected to produce a novel identification method for use in ME/C offices that is reliable, timely, and cost‐effective.  相似文献

Population-specific reference data are necessary for sex estimation in forensic anthropological practice. Currently, there are no population-specific data for Hispanics equivalent to data available for American Blacks and Whites. Individuals of Mexican origin represent the largest group of Hispanics in the United States (Spradley and Jantz. 2011. J Forensic Sci;56:289). This paper presents new population-specific sex estimation criteria for postcranial measurements for Mexican Hispanics. Metric data come from positively identified border-crossing fatalities at the Pima County Office of the Medical Examiner and documented cemetery collections curated at Universidad Nacional Autónoma de México and Universidad Autónoma de Yucatán. Stepwise variable selection procedures and discriminant function analyses were utilized to generate classification functions for postcrania. Sectioning points were also created for select measurements. Both the cross-validated classification rates and sectioning points achieved accuracy rates as high as 95% and 92%, respectively. These new criteria will improve sex estimation for US Mexico border crossers and Hispanics in the US.  相似文献

This article explores a geographical dilemma at the heart of union organizing in transnational corporations; namely, how to circulate union power across different spaces when existing labour struggles are generally restricted to single sites. Reflecting on the experience of the International Transport Workers' Federation, this paper argues that single site campaigns have been crucial to its organizing programme. Analysing cases involving dock workers in India and logistics workers in Turkey, it is noted that these struggles are resource intensive but potentially transformational, and should be theorized as ‘resonant places’ in a wider global organizing strategy.  相似文献
