This study investigated the value of antemortem (AM) and postmortem (PM) radiographs of the claviculae and C3-T4 vertebrae to identify skeletons of missing U.S. soldiers from past military operations. In total, 12 field-recovered skeletons and AM chest radiographs of 1460 individuals were used. For each skeleton, examiners analyzed an array of AM chest radiographs (up to 1000 individuals) and attempted to identify the correct PM/AM radiographic match. When examiners were able to compare all images within a single test, only true-positive identifications were made. When AM radiographs were presented one-at-a-time, in sequential order, and without examiners having knowledge of array size, erroneous identifications resulted but they were almost exclusively made by untrained examiners (accuracy = 35% vs. 90% for trained examiners). This study demonstrates the value of chest radiographs for the identification of disarticulated and even eroded skeletons, but only when methods are wielded by trained examiners.  相似文献

The determination of the cause and manner of death for a body recovered from the water can be difficult because of a lack of autopsy findings specific for drowning. This case report describes a 30-year-old man found submerged at the bottom of a hotel pool. An autopsy revealed scleral hemorrhages and fascial hemorrhages of multiple muscles of the anterior and posterior neck bilaterally. No evidence of traumatic injury was on the surface of the body. An investigation by law enforcement found no evidence of foul play. The occurrence of petechial and neck hemorrhage in a body recovered from the water is controversial, and a review of this literature will be given. We suggest that fascial hemorrhages of the muscles of the neck, as well as cephalic hemorrhages, can be explained by drowning-related elevated central venous pressure that is communicated to the head through the valveless veins of the neck.  相似文献

This paper articulates a citation‐based approach to science policy evaluation and employs that approach to investigate the impact of the United States’ 2001 policy regarding the federal funding of human embryonic stem cell (hESC) research. We evaluate the impact of the policy on the level of U.S. hESC research, the U.S. position at the knowledge frontier, and the strategic response of U.S. scientists. Consistent with recent research on the science of science and innovation policy, we employ a difference‐in‐differences approach using bibliometric data with the aim of analyzing the causal impact of the policy on cumulative research. Our estimates suggest that in the aftermath of the 2001 policy, U.S. production of hESC research lagged 35 to 40 percent behind anticipated levels. However, this relative decline was largely concentrated in the years 2001 to 2003 and ameliorated over time. The rebound in U.S. hESC research after 2003 was driven by contributions by researchers at elite U.S. institutions and U.S. researchers who collaborated with international partners. The results suggest that scientists respond strategically to research funding restrictions and that modest science policy shifts can have a significant influence on the within‐country composition of research and the pattern of global research collaboration.  相似文献

In this article I take up a conceptual question: What is the distinction between ‘the law’ and the behavior the law regulates, or, as I formulate it, the distinction between what is ‘inside’ the law and what is ‘outside’ it? That conceptual question is in play in (at least) three different doctrinal domains: the constitutional law doctrines regarding the limits on the delegation of legislative powers; the criminal law doctrines regarding mistakes of law; and the constitutional rights doctrines that turn on the distinction between state action and the acts of non-state actors. I argue that legal doctrines should turn solely on normative considerations and should not turn on answers to conceptual questions. However, the doctrines I discuss appear to turn on the conceptual question regarding what is ‘inside’ and ‘outside’ the law. I show how each of these doctrinal areas appears to raise this conceptual issue, and I explain how the doctrines might or might not escape being held hostage to conceptual controversy.  相似文献

Eine nebenvertragliche, dem Vertragsabschluss nachfolgende Beratungs- und Warnpflicht des (Haftpflicht-) Versicherers ist zumindest dann zu bejahen, wenn der Fall durch folgende Umst?nde gekennzeichnet ist: Eine neue Rsp, die dem Versicherer – dem auch der Wunsch des Versicherten nach umfassendem Versicherungsschutz bekannt war – wohl nicht entgangen sein kann, führt zu existenzbedrohenden Berufsrisiken einer bestimmten, überschaubaren Gruppe von nach denselben Bedingungen Versicherten (hier: Gyn?kologen). Geht es um die Verfehlung eines für eine solche Gruppe von Versicherungsnehmern typischen Deckungsbedürfnisses (also die Absicherung ihrer besonderen Berufsrisiken [hier: Haftung aus "wrongful birth"]), kann daher schon die (weitere) Kenntnis des Versicherers, dass der Versicherungsnehmer dieser Gruppe angeh?rt und umfassenden Versicherungsschutz anstrebt, eine solche Verpflichtung ausl?sen.  相似文献

As the new drug Spice hit the market in 2006 and was a hot topic in the media, the general issue of legal highs has been brought to the attention of a large number of (young) people. One of these so called legal highs are the seeds of Argyreia nervosa, also known as Hawaiian Baby Woodrose, which contains the psychotropic alkaloid lysergic acid amide (LSA). A study was designed to assess how driving ability is affected by Argyreia nervosa. However, the study could not be continued due to severe adverse effects in 3 of 4 subjects, such as cardiovascular dysregulation in two and a psychosis like state in one subject. All of the participants recovered completely within 9h after ingestion. Despite body normalized doses interindividually highly differing reactions in type and intensity were observed. Furthermore, fluctuating alkaloid contents in seeds and multi-drug intoxications make the use of this legal high far more dangerous than commonly believed.  相似文献
