The 1993 Supreme Court case Daubert v. Merrell-Dow Pharmaceuticals, Inc. underscores the importance of validating forensic science techniques. This research examines the validity of using posterior-anterior radiographs of the hand to make positive identifications of unknown human remains. Furthermore, this study was constructed to satisfy the requirements of Daubert's guidelines of scientific validity by establishing a standard methodology for hand radiograph analysis, testing the technique, and noting rates of error. This validation study required twelve participant examiners from the forensic science community, working independently, to attempt to match 10 simulated postmortem radiographs of skeletonized hands to 40 simulated antemortem radiographs of fleshed cadaver hands. The overall accuracy rate of the twelve examiners was 95%, while their collective sensitivity and specificity were 95% and 92%, respectively. However, the accuracy of each examiner was related to the amount of radiological training and experience of the observer. Six Ph.D. forensic anthropologists and four experienced forensic anthropology graduate students correctly identified all the matches. Participant examiners noted bone morphology, trabecular patterns of the proximal and middle phalanges, and distinctive radiopaque and radiolucent features as the anatomical features that aided the identification process. The hand can be an important skeletal element for radiographic positive identification because it contains 27 individual bones for comparative analysis. 相似文献

This paper reports a bilaterally symmetrical cranio-facial fracture pattern that is observed in self-inflicted, midline gunshot wounds. Five cases of self-inflicted gunshots wounds are presented as follows: two high-powered rifle cases, two shotgun cases, and one handgun case. In all five cases the remains were either decomposing or skeletonized and submitted to forensic anthropologists. Following identification, the main focus of the anthropological examination was the analysis of perimortem trauma to the skeleton. In each case, the skull was submitted in a highly fragmented state. Nevertheless, by focusing on the pattern of perimortem cranio-facial fractures, the anthropologists contributed key information regarding the circumstances of death. The observed symmetrical cranio-facial fracture patterns in the above cases are described in detail and interpreted. The specific location of the linear fractures is discussed, as well as the theoretical rationale behind the location in terms of skeletal architecture, such as buttresses, struts, and sutures. The interpretive framework provided by this paper may prove helpful to others who are faced with similar cases of cranio-facial fracturing. 相似文献

The relative effectiveness of two interventions for dealing with 200 court-referred spousal abusers is examined. The overall failure rate is 17.5%, with most recidivism occurring during the first 6 months after treatment. Offenders who completed a 14-week group treatment program called SAFE manifest significantly lower rates of recidivism (10.6%) than do offenders who did not complete the mandated treatment (38.8%). Some high-risk clients are referred to a cognitive restructuring treatment program called R&R, and those completing both programs (despite their high-risk status) have a recidivism rate of only 23.5%. Prediction of recidivism is difficult, with the LSI-R scores correctly predicting only 66% of the outcomes, using a cut score of 11.5. The exploration of other predictors is encouraged. 相似文献

We report a case in which a 33-year-old man was discovered unconscious following a fistfight with another man. Emergency neurosurgical efforts to repair a depressed temporoparietal skull fracture and associated brain injuries were unsuccessful. The forensic anthropologist and pathologist worked in tandem to sort out a complex combination of cranial evidence, including healed antemortem trauma, perimortem blunt force trauma, remote and recent neurosurgical intervention, and the craniotomy cut performed at autopsy. The victim had suffered head injuries and a right temporoparietal craniotomy ten years prior to death. The perimortem cranial fractures were centrally located within a surgically repaired roundel of bone involving portions of the right temporal and parietal bones. Reportedly, the victim was punched on the right side of his head as he was lying on the ground with the left side of his head against an asphalt surface. A primary question in the case was whether a blow with a fist could have produced the observed cranial injuries. To adequately answer that question, known data on the minimum amount of force required to fracture the temporoparietal region were compared to data on the amount of force generated by a blow with a fist. A biomechanics expert demonstrated that a single blow with a fist to the rigidly supported head of the victim could generate the required force to produce the observed fractures. The previous medical condition possibly predisposed the victim to the cranial fractures and contributed to the depressed nature of the fractures. Although depressed cranial fractures do not typically result from a blow with a fist, it was determined in this case that the fracture pattern was consistent with a punch to the head. 相似文献

When Congress ended the immigration of Chinese laborers in 1882, the Chinese population was over 95% male. While there has been much disagreement about why so few women came, the more fruitful question may be to ask how Chinese women were able to immigrate to the United States at all. Central to their immigration were legal arguments for lawful Chinese immigrants-primarily merchants and native-bom citizens-to bring their wives to the United States. Due to racial restrictions barring them from independent entry or marital naturalization, Chinese wives appealed to the uncodified gender privileges of their husbands in turn-of-the-century legal society: the natural right of a man to the company of his wife and children. In the face of a bureaucratic structure designed to sift immigrants by race, judges ruled that racial admission policies must conform to established gender privileges. The power of these arguments was tested in cases involving the deportation of Chinese women admitted as wives. While initially evading registration regulations for immigrants, Chinese women were unsuccessful at evading regulations concerning prostitution. This failure underscored the performative aspects of husbands' rights arguments, especially the image of the dutiful wife and husband and the class-based ideal of the elite merchant or citizen. 相似文献

This paper examines mobilization and conversion perspectives of opinion change during election campaigns. We demonstrate that opinion volatility during ballot proposition contests often reflects mobilization of awareness more than conversion of opinions. Furthermore, we find little support for the hypothesis that media spending affects opinions on the propositions examined here. An examination of other information sources suggests that many voters are able to use cues other than advertising when making decisions.An earlier version of this paper was presented at the Western Political Science Association meeting, Pasadena, California, March 22, 1993.

Many concerned with how government functions consider creating competition between bureaucracies an attractive option. Others are skeptical of what impact rival agencies have when they are operating within a political context. Reflecting these discrepant viewpoints, some scholars believe that regulators will compete vigorously for resources and responsibilities; others assert that agency members will act passively as they attempt to protect their autonomy. To assess these contrasting perspectives and determine why competitive agency structures might exist, the following analysis examines one of the classic situations where agencies can serve as functional substitutes: the relationship between the United States Forest Service and the National Park Service. The results demonstrate that agencies put far more weight on autonomy than competition. The principal advantage of functional rivalry for politicians—at least where federal lands are concerned—is to expand the choice set of alternatives available to them. 相似文献
