Sudden unexplained death in epilepsy occurs when epilepsy patients die suddenly and unexpectedly in the absence of recent tonic-clonic seizure activity. There is currently no known reliable indicator of acutely lethal seizure activity. Clinical studies record a relationship between recent (within 10-40 minutes) seizure activity and elevated serum prolactin levels, and postictal elevation of prolactin within peripheral vessels has proved clinically useful in determining recent seizure activity. The authors hypothesized that elevated prolactin could be detected in cerebral vessels by immunohistochemical stains, serving as a marker for sudden unexplained death in epilepsy. They conducted a retrospective study of individuals who died in their jurisdiction during the 14 years from 1986 through 1999. The study contained one group of individuals who died of sudden unexplained death in epilepsy, a group with epilepsy who died of some other cause, and a control group whose members died rapidly of a gunshot wound of the torso. Sections of hippocampus and neocortex were obtained and stained with a polyclonal prolactin antibody. No significant difference in the level of immunostaining for prolactin in cerebral vessels was found between the experimental and control groups. A review of the protocols used indicates that revision of certain aspects may provide better immunostaining and more conclusive results.  相似文献

There have been several anthropological studies on trauma analysis in recent literature, but few studies have focused on the differences between the three mechanisms of trauma (sharp force trauma, blunt force trauma and ballistics trauma). The hypothesis of this study is that blunt force and ballistics fracture patterns in the skull can be differentiated using concentric fractures. Two-hundred and eleven injuries from skulls exhibiting concentric fractures were examined to determine if the mechanism of trauma could be determined by beveling direction. Fractures occurring in buttressed and non-buttressed regions were examined separately. Contingency tables and Pearson's Chi-Square were used to evaluate the relationship between the two variables (the mechanism of trauma and the direction of beveling), while Pearson's r correlation was used to determine the strength of the relationship. Contingency tables and Chi-square tests among the entire sample, the buttressed areas, and the non-buttressed areas led to the null hypothesis (no relationship) to be rejected. Pearson's r correlation indicated that the relationship between the variables studied is greater than chance allocation.  相似文献

In the Italian nonprofit field, bank foundations face an increasing demand to account for their grant activity in forms that go beyond traditional financial statements. Consequently, bank foundations have developed specific reports in accordance with a 2001 Italian law that requires a mission report to be included within financial statements. This study investigates the peculiarities of social reporting documents in terms of standards used and formal characteristics, revealing different adoption levels. Contributing to an ongoing debate, the analysis of the reporting practices underlines how the due by law on social accounting could hamper the disclosure in nonprofit organizations.  相似文献

Summer bridge programs are supposed to connect a graduating high school senior’s summer to their first semester in college, easing the transition away from home and into a university setting. Although research is plentiful on the programs, assessments regarding the overall effectiveness of such programs have been mixed (e.g., Cabrera, Miner, and Milem 2013 Cabrera, Nolan, Danielle Miner, and Jeffrey Milem. 2013. “Can A Summer Bridge Program Impact First-Year Persistence And Performance?: A Case Study Of The New Start Summer Program.” Research in Higher Education 54(5): 481498.[Crossref], [Web of Science ®] [Google Scholar]; Douglas and Attewell 2014 Douglas, Daniel, and Paul Attewell. 2014. “The Bridge and the Troll Underneath: Summer Bridge Programs and Degree Completion.” American Journal of Education 121(1): 87109.[Crossref], [Web of Science ®] [Google Scholar]; Grayson 2003 Grayson, J. Paul. 2003. “The Consequences of Early Adjustment to University.” Higher Education 46(4): 411429.[Crossref], [Web of Science ®] [Google Scholar]). As Cabrera, Miner, and Milem (2013 Cabrera, Nolan, Danielle Miner, and Jeffrey Milem. 2013. “Can A Summer Bridge Program Impact First-Year Persistence And Performance?: A Case Study Of The New Start Summer Program.” Research in Higher Education 54(5): 481498.[Crossref], [Web of Science ®] [Google Scholar]) note, many of the studies collect data from participants in a one-time satisfaction survey and/or do not have an equivalent group of students who did not participate in the program from which to compare effectiveness. Our proposed study mitigates these flaws by employing a nonequivalent-groups quasi-experiment (NEG). Our bridge program—called Early Start (ES)— tapped into social, emotional, and academic engagement, as we sought to integrate the students into the university and school communities while holding high expectations and actively involving them in their own learning (Tinto 2004 Tinto, Vincent. 2004. Student Retention and Graduation-Facing the Truth, Living with the Consequences. Washington, DC: The Pell Institute for the Study of Opportunity in Higher Education. [Google Scholar]). Results suggest that not only were students enrolled in our program better socially and emotionally integrated into the university during their first year but they also scored better on content-based political science questions at the end of the fall semester, compared to their non-Early Start peers. Finally, aggregated data indicate an increase in retention for Early Start participants.  相似文献

Sexual minority youth (youth who are attracted to the same sex or endorse a gay/lesbian/bisexual identity) report significantly higher rates of depression and suicidality than heterosexual youth. The minority stress hypothesis contends that the stigma and discrimination experienced by sexual minority youth create a hostile social environment that can lead to chronic stress and mental health problems. The present study used longitudinal mediation models to directly test sexual minority-specific victimization as a potential explanatory mechanism of the mental health disparities of sexual minority youth. One hundred ninety-seven adolescents (14–19 years old; 70 % female; 29 % sexual minority) completed measures of sexual minority-specific victimization, depressive symptoms, and suicidality at two time points 6 months apart. Compared to heterosexual youth, sexual minority youth reported higher levels of sexual minority-specific victimization, depressive symptoms, and suicidality. Sexual minority-specific victimization significantly mediated the effect of sexual minority status on depressive symptoms and suicidality. The results support the minority stress hypothesis that targeted harassment and victimization are partly responsible for the higher levels of depressive symptoms and suicidality found in sexual minority youth. This research lends support to public policy initiatives that reduce bullying and hate crimes because reducing victimization can have a significant impact on the health and well-being of sexual minority youth.  相似文献

In 1956, the Chinese Communist state launched its official language policy, which included the promulgation of a standard spoken language, called Putonghua. Their justification for this policy and their methods for implementation were guided by intellectual and ideological frameworks that formed during decades preceding the policy's rollout. In particular, Communist language reform was predicated on the conceptualization of Putonghua as a holistic language meant to serve the national body—and of local dialects, called fangyan in Chinese, as dependent on Putonghua for their very definition. This article interrogates the history of this framework. Focusing on dialect surveys from the 1930s, Chinese interpretations of Marxist linguistic theory in the early years of the Communist state, and methods of Putonghua promulgation in the late 1950s, this article reconstructs the epistemological regimes that gave meaning to the concept of independence and autonomy as they related to language in modern China.  相似文献

Although future orientation influences a variety of desirable behaviors, few studies have examined the relationship between economic resources and future orientation. In this study, we investigated whether and how asset ownership influences future orientation. We analyzed survey data collected from 3,007 Ghanaian youth and their parents. We used factor analysis to determine the psychometric qualities of our instruments, and propensity score analysis to examine the relationship between asset ownership and future orientation. Results suggest that asset ownership influences future orientation of youth and their parents. However, the direction of the relationship depends on the type of asset. Ownership of household possessions, including televisions contributes to higher levels of future orientation, but livestock ownership has a negative effect on future orientation. We discuss implications for future research, as well as programs for youth and their families.  相似文献
