Arteriovenous malformations of the scalp are potential sources of serious bleeding because of their location, inherent weakness, and high flow rates. A 40-year-old man used his vascular lesion as a means of suicide. Selected aspects of the historical background, diagnosis, and treatment of these vascular disorders are described. 相似文献
Interpretations of antemortem and perimortem trauma are complicated when dealing with cases involving extreme exposure to fire. This investigation attempts to discern the signatures of perimortem trauma from heat related trauma. Femora of domestic pig, sus scrofa, with minimal soft tissue and articulated patellae were subjected to varying traumatic forces. Skeletal elements were impacted with blunt and sharp forces, cut with varying instruments, subjected to torsional forces of shot. Bones were burned in various situations in conjunction with Knox County Rural/Metro Fire Department training exercises conducted in Knox County, Tennessee. Following recovery, fragments were subjected to radiographic, macroscopic, and microscopic analyses. Skeletal elements were reconstructed to permit accurate comparison with pre-fire visual records. In addition, fracture surfaces were examined under both transmitted light and scanning electron microscopy in an attempt to discern surface signatures of the causal fracture (trauma, heat, or situational). Results indicate that signatures of sharp force trauma remain evident following incineration. Furthermore, radiopaque spatter was not observed in any shot specimen. However, these initial findings suggest that the interpretation of blunt force and torsional trauma requires a rigorous examination and comparison of fracture patterns in conjunction with surface morphology. 相似文献
Based on official election records from East German constituencies, this paper examines the importance of strategic voting in German Bundestag elections. The results show that: (1) voters do indeed cast strategic ballots; (2) overall, the CDU and SPD benefit most often from strategic votes; (3) up to 9% of voters in the constituency cast strategic votes; and (4) that number was large enough to tip the scales in a number of constituencies, thus affecting the allocation of surplus seats in the Bundestag. 相似文献
Abstract: Trotter and Gleser’s ( 1 - 3 ) stature equations, conventionally used to estimate stature, are not appropriate to use in the modern forensic context. In this study, stature is assessed with a modern (birth years after 1944) American sample (N = 242) derived from the National Institute of Justice Database for Forensic Anthropology in the United States and the Forensic Anthropology Databank. New stature formulae have been calculated using forensic stature (FSTAT) and a combined dataset of forensic, cadaver, and measured statures referred to as Any Stature (ASTAT). The new FSTAT‐based equations had an improved accuracy in Blacks with little improvement over Ousley’s ( 4 ) equations for Whites. ASTAT‐based equations performed equal to those of FSTAT equations and may be more appropriate, because they reflect both the variation in reported statures and in cadaver statures. It is essential to use not only equations based on forensic statures, but also equations based on modern samples. 相似文献
Isoscape refinement is an essential component for accurately predicting region‐of‐origin in forensic investigations involving isotope analysis of unidentified human remains. Stable oxygen (δ18O) and hydrogen (δ2H) isotopes were measured from 57 tap water samples collected across Mississippi to model refined isoscapes for the state. A tap water conversion equation, δ18Otw=1.64 δ18Op?31.35, was developed for the southeastern USA to test the prediction accuracy of the δ18Otw isoscape using individuals with known residential histories. A local Mississippi resident (USAFA‐134) was assigned with 90% probability to the correct region‐of‐origin reported by the participant. Assignments for Georgia residents (USAFA‐118 and USAFA‐205) had variable results, predicting USAFA‐118 from Mississippi and USAFA‐205 as a nonlocal resident. Stable isotope values often overlap geographically and a multi‐isotope approach should be used when narrowing region(s)‐of‐origin(s). This study demonstrates the utility of refining isoscapes and the importance of tissue calibration in prediction assignments of human remains. 相似文献
International statebuilders’ strategy to achieve a peaceful and multi-ethnic Kosovo has shifted from the top-down institutionalization of a multi-ethnic society in the UNMIK period (1999-2008), to the neutral and technical administration of society, with a focus on the reduction of the ethnic divide (EULEX and ICO after 2008). However, despite this evolution in the understanding of statebuilding, this article identifies a dominant sentiment among practitioners of both periods, shared also by academic scholars: further international assistance is key to building a truly inclusive peace. It is argued that this shared assumption rests on the belief that the problems in Kosovo are caused by ethnic thinking—a psychosocial dysfunction. This psychosocial framing of the problem—no matter whether the solution is a process of promoting or de-emphasizing ‘ethnic’ differences—involves a constant and endless international management of Kosovo. 相似文献
Although the oxytocin receptor gene (OXTR) is involved in aggression and social affiliation, it has not been examined in gene-environment interaction studies. This longitudinal study examined the effect of genetic variants in OXTR and its gene-environment interaction with perceived deviant peer affiliation in the trajectories of antisocial behavior in 323 adolescents (182 males) from 13 to 18 years. Annual assessments of reactive and proactive aggression, delinquency, and friends’ delinquency, as well as DNA at age 17 were collected. Gene-based tests yielded no main effect of OXTR, but revealed a significant gene-environment interaction in proactive aggression and delinquency. Variation in the OXTR might affect the influence of deviant peer affiliation on antisocial behavior, contributing to a better understanding of individual differences in antisocial behavior.
While Denmark is widely known as a global exporter of cryopreserved sperm, Danish women’s eggs face a very different fate. This paper combines legal and rhetorical analyses with the concept of sociotechnical imaginaries. In establishing the genealogy of the sociotechnical imaginaries that shaped Danish regulation of the cryopreservation of eggs, we analyse the relevant Acts, Bills, preparatory work, and readings in Parliament, along with the concurrent public and ethical debates that over time relaxed the legal limit for the cryopreservation of eggs to the current five years and today continue to ignite discussions on elective egg freezing. We rely on welfare-state perspectives to discuss why reproduction, in the Danish context, is seen as a legitimate and appropriate sphere to regulate, and we turn to feminist theorizing to discuss the gendered implications captured in the sociotechnical imaginaries of the “Moral State”, “technologies to be tamed”, “the nuclear family”, and “technology as equality and hope”. We end by discussing how an interdisciplinary approach enriches our understanding of the legal, cultural, and political entanglements related to putting eggs on ice. 相似文献
