Postmortem magnetic resonance imaging (MRI) is rarely used for the radiologic assessment of gunshot injuries, although it has clear advantages over postmortem computed tomography (CT) with regard to the imaging of soft tissue injuries. Another benefit in using MRI is that lodged projectiles composed of nonferromagnetic material such as lead present only marginal metal artifacts compared with severe artifacts on CT. This case report presents CT and MRI findings in a case with two gunshot wounds to the neck: a perforating wound and a nonperforating wound with a lead bullet lodged in the cervical spine. The decedent underwent CT and MRI before the scheduled autopsy. A ring of radiopaque material under the dermis in the fatty tissue was identified at both entrance wounds on CT, which was indicative of contact shots. The perforating gunshot was clearly indicated on CT by bullet fragments along the wound channel through the perforated 6th cervical vertebra and the fractured cricoid cartilage at the exit wound. The second trajectory, however, was only assumed based on the presence of gunshot residues at the entrance wound and the position of the lodged bullet. The radiologic assessment was severely impeded by the metal artifacts on CT. Barely noticeable metal artifacts on MRI allowed for clear visualization of the soft tissue injuries and the ruptured medulla oblongata. Only MRI clarified the soft tissue injuries of the brainstem noninvasively, which could provide specific and graphic information on the rapidity of death and the incapacitation of the victim.  相似文献

Hacking trauma is prevalent in forensic cases involving genocide and dismemberment, but research into the identification of this type of trauma is lacking. The present study examines characteristics of hacking and blunt force skeletal trauma in order to determine if there is a point at which blunt force trauma becomes distinguishable from hacking trauma. Ten implements with a range of blade angles (i.e., the striking surface of the implement) were used in conjunction with a controlled-force hacking device to impact 100 limb bones of white-tailed deer (Odocoileus virginianus). Observations of the trauma included the occurrence and degree of fragmentation, the entrance widths of the impacts, and composite scores of six hacking characteristics, especially the distinctive V-shaped kerf. ANOVA tests and regression analyses were used to assess the relationships between these characteristics and the blade angles. A significant relationship (p-value = 0.011) was found between the composite hacking scores and the blade angles, indicating that blunt force and hacking trauma can be distinguished. The entrance widths of the impacts exhibited a significant relationship with the blade angles (p-value = 0.037). There was also a significant relationship between the visibility of a V-shaped kerf in the bones (p-value = 0.003), with visibility decreasing around the 60° blade angle. These data should assist in establishing guidelines to differentiate hacking and blunt force skeletal trauma in cases where the implement is on a spectrum between sharp and blunt.  相似文献

Focusing on identity development explorations enables a greater understanding of contexts that affect immigrant adolescents. Utilizing thematic and grounded narrative analysis of 46 journal writings, during a one-month period, from first and second generation Vietnamese adolescents ranging in age from 15 to 18 (26 residents of a culturally and politically active ethnic enclave in Southern California; 20 adolescents living outside the enclave), this study establishes ways in which a focus on social context and exploration processes illuminates the complexity of immigrant adolescents’ identity formation. The two groups shared many similarities, including precipitants to exploration and steps undertaken to explore identity. However, two factors—social and cultural influences and emotional reactions—revealed interesting contrasts distinguishing enclave from non-enclave dwelling Vietnamese adolescents. Data also suggested that immigrant adolescents strive to integrate different domains of identity (ethnicity, gender, career) both with one another and with the historical, social, and cultural contexts they occupy.

Youth with same-sex desire undergo a process of narrative engagement as they construct configurations of identity that provide meaning and coherence with available sexual taxonomies. This article presents a theoretical analysis and four case studies centering on the relationship among context, desire, and identity for youth with same-sex desire. Through an interpretive, holistic analysis of the personal narratives of youth, we examine the integration of same-sex desire, behavior, and identity in the general life story and the selective appropriation of elements of “master narratives” of sexual identity development. Narratives were characterized by challenges to integrate desire, behavior, and identity into a configuration that conformed to the received sexual taxonomy. Implications for theory and further research on sexual identity development are discussed.  相似文献

The current cross-sectional study investigated the links between various dimensions of organized activity involvement and depressive symptoms, loneliness, and peer victimization in an ethnically and economically diverse sample of adolescents (N = 152; 58% female). Results indicate that adolescents who were involved in organized activities for more years also reported lower levels of loneliness. There was evidence of diminishing returns when adolescents were very highly involved in organized activities; those who were either under- or over-involved reported the highest levels of depressive symptoms. Conversely, findings indicate that adolescents who participated in a narrow or wide range of activity contexts reported the lowest levels of depressive symptoms. In addition, results suggested that the relation between organized activity involvement and adjustment differs among adolescents from diverse ethnic and socioeconomic backgrounds. Findings from the current study also underscore the importance of considering multiple indices of activity involvement when assessing its association with adjustment.

What motivates citizens to run for office? Recent work has shown that early life parental socialization is strongly associated with a desire to run for office. However, parents not only shape their children’s political environment, they also pass along their genes to those same children. A growing area of research has shown that individual differences in a wide range of political behaviors and attitudes are linked to genetic differences. As a result, genetic factors may confound the observed political similarities among parents and their children. This study analyzes Swedish register data containing information on all nominated and elected candidates in the ten parliamentary, county council, and municipal elections from 1982 to 2014 for a large sample of adoptees and their adoptive and biological parents. By studying the similarity in political ambition within both adoptive and biological families, our research design allows us to disentangle so-called “pre-birth” factors, such as genes and pre-natal environment, and “post-birth” factors like parental socialization. We find that the likelihood of standing as a political candidate is twice as high if one’s parent has been a candidate. We also find that the effects of pre-birth and post-birth factors are approximately equal in size. In addition, we test a number of potential pre- and post-birth transmission mechanisms. First, disconfirming our expectations, the pre-birth effects do not seem to be mediated by cognitive ability or leadership skills. Second, consistent with a role modeling mechanism, we find evidence of a strong transmission in candidacy status between rearing mothers and their daughters.  相似文献

Pay for performance (PFP) remains one of the most controversial policy debates in the New Public Management reform era. Skepticism about PFP in the public sector is often grounded in theories of public service motivation that suggest a misalignment between PFP's focus on extrinsic market‐based pay incentives and intrinsically motivated government workers. Frequently missing from this analysis, however, is any consideration for whether PFP leads to positive “sorting” effects on the composition of a government agency's workforce through attraction, selection, and attrition processes. Using data from two waves of the Schools and Staffing Survey, the authors examine whether PFP influences the sorting patterns of K–12 public schoolteachers across U.S. school districts. Findings show that, on average, school districts that adopted PFP secured new teacher hires who had graduated from colleges and universities with average SAT scores that were about 30 points higher than the new teacher cohorts hired by districts that did not adopt PFP.  相似文献

In recent years, Congress has recurrently failed to meet its minimum responsibilities in federal budgeting. This article analyzes whether it is possible to repair this problem, using concepts popularized by Allen Schick in his influential article “The Road to PPB.” His article compared the PPB reform effort to the history of budget process reforms that started with the design of the executive budget. It publicized a logical sequence of budget process improvements that started with control and then advanced through management and planning. The article did not substantially address the role of Congress, but eight years after it was published, Congress reasserted its constitutional role in the budget process. Its record of performance since then has ranged from mixed to dysfunctional. The Congress has been criticized for budgetary delays, micromanagement, myopia, procrastination, indiscipline, and an inability to prioritize intelligently. If these faults are set in stone, then an integrated system of budgeting, as described in “The Road to PPB” and related work, is unattainable. On the other hand, if reform of Congressional budgeting is politically feasible, improvements to that system can utilize the unique contributions that a legislature can make to a good system of budgeting.  相似文献

The following is a brief survey of Marx and Engels’ views on ecology, from the viewpoint of their relevance for 21th-century ecosocialism. While there are some serious limitations in the way both consider the “development of productive forces,” there are powerful insights in their discussion of the destructive consequences of capitalist expansion for the environment—an expansion that generates a disastrous metabolic rift in the exchanges between human societies and nature. Some ecological Marxists distinguish between “first stage ecosocialists”—who believe that Marx analyses on ecological issues are too incomplete and dated to be of real relevance today—and “second stage ecosocialists,” who emphasize the contemporary methodological significance of Marx’s ecological critique of capitalism. This paper tries to argue for a third position (which probably could be accepted by several people of the two groups above): Marx and Engels’ discussion on ecological issues is incomplete and dated but despite these shortcomings it does have real relevance and methodological significance today.  相似文献
