Post-vasectomized azoospermic semen samples (N = 6) were analyzed for short tandem repeats (STR) on the Y-chromosome by using Y-PLEX 6 and the 310 Genetic Analyzer. We have observed a wide variation in the yield of extracted DNA from 12.5-1,000 ng. This variation was attributed to the number of epithelial and/or white blood cells that are present in these azoospermic samples. DNA profiles of these vasectomized males were obtained for all six Y-STR loci, namely DYS393, DYS 19, DYS389II, DYS390, DYS391, and DYS385 amplified by using the Y-PLEX 6. 相似文献

Within the last 35 years health care expenditures have increased from $12 billion t o over $350 billion. Recent concern over these costs have led to a reevaluation of the health care delivery system in the United States. This paper reviews four emerging cost containment models. The discussion focuses on the "market-likell incentives introduced in to the health care delivery system by such strategies. 相似文献

It is important to examine the concomitants of depressive symptoms reported by battered women because of the high frequency and potentially vulnerability-enhancing effects of these symptoms within battering relationships. In the present study, 10 environmental and behavioral skills correlates of depressive symptoms were examined in 136 battered women. The results of the Simultaneous Multiple Regression suggested that 46% of the variance in depression scores could be accounted for by scores on measures of these 10 variables. Four variables were found to be uniquely and significantly associated with depressive symptoms: self-reinforcement, realistic assessment, number of losses, and a history of depression. These results suggest that battered women who realistically assess their battering relationship and who report poor self-reinforcement skills, losses, and histories of depression may be at particular risk for depression. 相似文献

The onset of suicidal ideation in childhood and adolescence 总被引:1,自引:0,他引:1

Event history analysis is used to address questions about the timing of first suicidal ideation during preadolescence and adolescence. Are suicidal thoughts atypical during development? Does the age trajectory of suicidal thoughts parallel that of suicidal actions? Do factors that moderate the risk of suicidal actions also moderate the risk of suicidal thoughts, and does their influence vary by developmental stage? Based on life history data from 364 college students, results indicate that suicidal thoughts in childhood are typical and that the risk of such thoughts begins to increase by age nine. Risk rates are affected by demographic factors (gender, race) and by the experience of parental absence. However, the influence of these factors depends on developmental stage, with whites being at increased risk only during adolescence, and parental absence having its strongest effect during preadolescence. In sum, this study suggests that many children and adolescents contemplate suicide, that the risk of doing so begins to increase at an early age, and that clear similarities exist between those groups at heightened risk for suicidal thought and those at heightened risk for suicidal action. Moreover, this study illustrates the power of employing an analytic technique suitable for modeling transitions. Finally, it highlights the need to model differential influences on suicidal ideation at different stages in development. 相似文献

The Chinese party-state has been depicted in three major forms by the existing studies – the authoritarian state, developmental state and corporatist state. These depictions, however, only offer a partial understanding of the Chinese party-state and have failed to grasp its totality. Drawing upon the theoretical insights of Antonio Gramsci, this article contends that Chinese economic reform inaugurated in 1978 has been a top-down passive revolution and that, after three decades of reform, the role of the Chinese state has been changing from steering the country’s passive revolution to establishing capitalist hegemony. However, it should be noted that although the Chinese state has been undergoing a hegemonic transformation, capitalist hegemony has not been unambiguously established in the country. Some workers have given consent to the ruling class’s leadership, but a segment of workers has been able to transgress hegemony to formulate a radical critique of capitalists and the state. The transition to hegemony in China is a chaotic and tumultuous process of class struggles between the ruling class and the working class. 相似文献

Suicide is a leading cause of death for adolescents. A number of problem behaviors associated with youth suicide fall into the purview of law enforcement personnel, and they are therefore in a position to detect risk and prevent suicidal behaviors. Eight hundred one youth identified as having school difficulty, a group at increased risk for both suicide and legal problems, participated in a paper and pencil survey followed by an interview focusing on suicide risk and protective factors. Linear regression was used to examine the ability of factors within each risk and protective factor dimension to predict current suicide risk. The study goal was to determine the most relevant factors influencing suicide risk in each domain examined. Findings are discussed in terms of implications for assessment and policy for law enforcement personnel. 相似文献

The practice and popularity of restorative justice (RJ) in education has been growing in recent years. RJ can be understood in dramatically different ways by those implementing it. For some, RJ is about creating an environment of and for student engagement that challenges traditional systems of discipline and facilitates learning. For others, RJ is simply another tool for solidifying compliance and meting out punishment, albeit in a kinder, gentler way. This comparative case study focused on the use of RJ in one school in Scotland and one in Canada, exploring the intersection between educator intentions and student experiences. I determined that the key element is not the implementation of RJ, but the school’s predominant relational objectives. In a school where relational objectives are of social control, RJ is utilized to strengthen that control. Where the relational objectives are of social engagement, RJ is utilized to strengthen that engagement. RJ in schools is a window into what is most fundamental to students: relationships. The study argues that RJ, by itself, does not guarantee certain qualities of relationship, but it does allow us to examine those qualities and ask questions of how school relationships are used to engage and/or control students. 相似文献
