The azygos vein ascends along the thoracic spine through the mediastinum and drains into the superior vena cava at the level of the fourth thoracic vertebra. Fracture-dislocation of the mid-thoracic spine, as a result of blunt thoracic trauma, can tear the azygos vein. Four such fatal cases (three motor vehicle accidents and one fall) were studied, only one of which was recognized prior to death. The vein can also be torn, in the absence of skeletal injuries, by horizontal acceleration/deceleration forces. The pathologist must consider azygos vein laceration as a possible cause of either hemothorax or hemomediastinum or both in a victim of a blunt chest trauma, if that individual had persistent hypotension during the few hours before death and no identifiable source of hemorrhage can be found postmortem in sites such as the heart, great vessels, lung, and chest wall. A fracture-dislocation of the thoracic spine may not necessarily be present. Azygos vein laceration seems to be an uncommon cause of hemothorax and hemomediastinum; however, this injury is probably more frequent than is implied by the few cases described in the medical literature.  相似文献

A meta-analysis investigating the relationship between marital satisfaction/discord and intimate partner violence (IPV) in heterosexual relationships was conducted with 32 articles. Overall, a small-to-moderate effect size (r = −0.27) indicated a significant and negative relationship existed between marital satisfaction/discord and IPV. Moderator analyses found no differences between effect size based on construct examined (discord or satisfaction). However, the magnitudes of observed effect sizes were influenced by other moderator variables, including the use of standardized versus non-standardized measures, gender of the offender and victim, role in the violence (perpetrator versus victim), and sample type (clinical versus community). The data suggests that gender is an especially important moderator variable in understanding the relationship between marital satisfaction/discord and IPV.  相似文献

This article examines Marshall Dimock's thought on the relation between public administration and law. The examination revolves around his book, Law and Dynamic Administration,but also incorporates insights from his many other works. Dimock treated the idea of rule of law as an important source of authority and guiding principles for both the public administrative and legal professions. He criticized the legal profession harshly for its tendency in this century to disparage and reject law as such a source. Its treatment of law has led to many abuses that affect the legitimacy and efficacy of all who govern in our society. Dimock hoped to reunify the fields with a common jurisprudence that is mindful of public, institutional needs. In the process, he pressed the point that public administrators should be legal artisans in their own right, contributing confidently to the content and processes of the law for public benefit.  相似文献

This article argues for the importance of more focused scholarly attention on the development of mass‐elite linkages ‐ and in particular those linkages that transcend the electoral connection ‐ for understanding democratic consolidation, drawing on the post‐communist experience of the Czech Republic as a case study. Starting with the government's loss of its majority in the 1996 Czech elections amidst favourable economic conditions, we argue that this electoral result goes beyond the response to policy priorities to point to larger deficits in the development of channels of access and communication in the policy‐making process. Such deficits, characteristic of the post‐communist experience regionally, are not merely legacies of the stunted civil societies of the communist period, but also reflect a post‐communist style of governance that may itself discourage regularized citizen and associational input. As the episodic electoral connection alone cannot bear the weight of democratic consolidation, the risk is a pattern of mass‐elite linkages that creates a punctuated politics of elections and street demonstrations.  相似文献

This study examines whether the incidence of crossburnings rises in areas where white supremacist organizations, such as the Christian Knights of the Ku Klux Klan, have held rallies or demonstrations. Using data from two public interest groups, Klanwatch and North Carolinians Against Racial and Religious Violence, we track crossburnings and white supremacist activities in 100 North Carolina counties annually for the period 1987–1993. Various statistical models, including an event count analysis that allows each county to have its own level or reporting bias, indicate that the base rate at which crossburnings occur rises sharply in counties where a demonstration has taken place. Since none of the suspected crossburners has apparent ties to white supremacist groups, it may be that white supremacist rallies encourage fellow travelers to engage in this form of racial intimidation.  相似文献
