The purpose of this paper is to assess the effects of data aggregation on a specification of the relationship between sex and arrest rate trends. The analysis focuses on the empirical implications when arrest data are aggregated across dimensions that are likely to affect the sex-crime relationship. The data for the analysis consist of 4,119,358 male and female adult arrests in New York State for the 13-year period ending in 1984. Results indicate that race, regional differences, and the legal seriousness of the arrest charge produce significantly different patterns of sex convergence across time. On the basis of these results, we suggest serious limitations in past analyses of female crime rates and in the value of Uniform Crime Report (UCR) data for addressing theoretically relevant questions concerning the social correlates of official crime. 相似文献

In a case of first impression, and one of the few cases interpretingthe statute at issue, a district court in New York City hasheld that the Audio Home Recording Act, 17 USC sections 1001et seq. (AHRA), does not immunize a distributorof digital audio recording devices (DARDs) from copyright liabilitywhen the infringement claims are based on the distributor'sallegedly infringing activity in its simultaneous role as asatellite radio broadcaster. The case illustrates the ambiguousnature of digital transmissions, which can be treated as distributionsof musical works as well as digital performances. 相似文献

This research examines the utility of patella outline shape for matching 3D scans of patellae to knee radiographs using elliptical Fourier analysis and subjective methods of human visual comparison of patellae across radiographs for identification purposes. Repeat radiographs were captured of cadaver's knees for visual comparison before patellae were extracted and skeletonized for quantitative comparisons. Quantitative methods provided significant narrowing down of the candidate pool to just a few potential matches (<5% of original sample), while the human analysts showed high capacity for correctly matching radiographs, irrespective of educational level (positive predictive value = 99.8%). The successful computerized matching based on a single quantified patella trait (outline shape) helps explain the potency achieved by subjective visual examination. This work adds to a growing body of studies demonstrating the value of single isolated infracranial bones for human identification via radiographic comparison. 相似文献

The Valsalva maneuver is used in clinical medicine for the diagnosis and/or treatment of various cardiovascular conditions. It can also be used in activities of daily living, such as defecation. Due to the cardiovascular effects produced during the Valsalva maneuver, it may be contraindicated in certain medical conditions and could be a trigger of sudden cardiac death. The incidence and prevalence of death following Valsalva maneuver in the presence of underlying cardiovascular disease, or “commode cardia,” has not been examined. In 2012, the Wayne County Medical Examiner's Office (Detroit, MI) investigated 21 deaths that occurred on the toilet, fourteen of which were due to cardiovascular disease. In another 31 deaths in the bathroom due to cardiovascular disease, the possibility that the decedent defecated immediately prior to death could not be excluded. Hence, the incidence of commode cardia in this population ranges from 2.3 to 7.4% of all cardiovascular‐related deaths. 相似文献

This article analyzes the science fiction (SF) manga 7 Billion Needles in order to show how an overt visual and narrative emphasis on character emotions and psychology can contribute to science fiction's political potential by emphasizing the similarities between dialogue as a form of emotional therapy and the act of exploring alternative environments. This article also demonstrates how science fiction manga provides a template by which character emotion can become so integrated into the SF narratives and worlds that emotion itself becomes ‘science fictional’. 相似文献

Change in perspective between antemortem and postmortem imaging sessions (radiograph to radiograph and surface scan to radiograph) may cause different 2D renderings of the same osseous element complicating comparisons for identification. In this study, clavicle shape changes due to radiographic positioning and 3D laser scanning were examined in 20 right‐side specimens, as pertinent to chest radiograph comparisons. Results indicate substantial changes in clavicle form with short source‐to‐image receptor distance, elevation of the element from the image receptor, and movement of the element away from the center beam (10% mean square for shape). Although quantitative shape differences were small when the clavicle was in close opposition to the image receptor (3% mean square), important qualitative differences remained with large distances from the center beam (e.g., conoid tubercle presence/absence). The significance of these results for image superimposition and computer‐automated‐shape‐based searches of radiographic libraries to find matching candidates is discussed. 相似文献

In recent years Western policy towards Afghanistan has been marked by inconsistencies and errors. This article explores United States (US) soldiers' perceptions of the enemy in Afghanistan based on oral history interviews with dissenting combat soldiers who served in the Afghan theatre. By foregrounding soldiers' attitudes towards the enemy, this study includes marginalized voices, often overlooked, that challenge prevailing misconceptions. General David Petraeus, the former commander of US forces in Afghanistan, has argued that significant battlefield decisions are not reserved for generals alone. Petraeus' counterinsurgency programme promotes ‘strategic corporals’ whose decisions hold important consequences. If strategic corporals are involved in military decision-making, it follows that their interpretation of the conflict may also hold strategic implications for the researcher. Soldiers' views of war are not the final, authoritative verdict. However, this article suggests that these strategic corporals should be included in a complex matrix of interpretation to broaden US understanding of the enemy. 相似文献
