A 22-year-old Korean soldier, who had received blows to the neck and epigastrium from an officer 10 h earlier, suddenly died after massive hematemesis. He had been in relatively good health except for episodes of blood-tinged vomiting approximately 5 and 7 months prior to this event. Postmortem examination revealed angiodysplasia involving the gastroesophageal junction, and the stomach was distended with blood. No abnormal findings were present around the whole viscera, and the duodenum was free of blood. The pathologic significance of upper gastrointestinal angiodysplasia as a potential source of bleeding and a chronologic correlation between the trauma and bleeding are discussed. 相似文献

We tested competing hypotheses derived from Gottfredson and Hirschis (1990) general theory and Moffitt's (1993a) developmental theory of antisocial behavior. The developmental theory argues that different factors give rise to antisocial behavior at different points in the life course. In contrast, the general theory maintains that the factor underlying antisocial behavior (i.e., criminal propensity) is the same at all ages. To test these competing predictions, we used longitudinal data spanning from age 5 to age 18 for the male subjects in the Dunedin Multidisciplinary Health and Development Study. Using reports from three sources (parents, teachers, and the boys themselves), we estimated second-order confirmatory factor models of antisocial behavior. These models provided consistent support for the developmental theory, showing that separate latent factors underlie childhood and adolescent antisocial behavior. Moreover, we found that these childhood and adolescent factors related in ways predicted by Moffitt's developmental theory to four correlates of antisocial behavior: Childhood antisocial behavior was related more strongly than adolescent antisocial behavior to low verbal ability, by per activity, and negative/impulsive personality, whereas adolescent antisocial behavior was related more strongly than childhood antisocial behavior to peer delinquency. The two underlying latent factors also showed the predicted differential relations to later criminal convictions: Childhood antisocial behavior was significantly more strongly associated with convictions for violence, while adolescent antisocial behavior was significantly more strongly associated with convictions for nonviolent offenses. 相似文献

Why is that former dominant or single party regimes, especiallythose in Africa, have generally survived and even emerged strengthenedafter the introduction of multi-party competitive elections?In Côte d'lvoire since 1990 the ruling party has beenable to win elections by using incumbency to present itselfas the organization most likely to be capable of putting togethera winning coalition. In a society segmented by a multiplicityof cultural and religious divisions and where political poweris a zero-sum game, the logic of democratic representation meansthat no group can afford to be excluded. Yet in the 1990 and1995 Ivorian elections .the opposition attacked die ethnic characterof the government and deliberately mobilized ethnic minorities,regional and religious (Islamic) sentiments. They thereforefailed to escape, in electoral terms, from their extremely localizedstrongholds. Their attempt to mobilize around an anti-foreignerplatform in 1990 rebounded in 1995 when the government itselftook over their ultra-nationalist stance by excludingnon-Ivorians from the elections. The consequent exclusion ofthe opposition's favoured Presidential candidate and the failureof the opposition alliance to agree on a non-northern, non-Islamicalternative candidate led to a violent boycott and the eventualcollapse of the opposition alliance. 相似文献

Incarceration rates in the United States dramatically increased over the past several decades. This trend has drawn significant academic attention to prison overcrowding and its potential effect on inmate misconduct. The empirical relationship between inmate misconduct and overcrowding, however, is less than clear. To be sure, studies indicating positive, negative, and null relationships can all be found in the literature. The current research subjects this body of literature to a meta-analysis in an effort to: (1) clarify the direction and strength of the relationship between overcrowding and rates of prison misconduct across all studies, and (2) to uncover the degree to which variation in research outcomes can be attributed to methodological differences across studies. Results indicate that prison crowding has little substantive impact on inmate misconduct. Implications of the findings are discussed in detail. 相似文献

Those in need of employment and training programs face a variety of difficulties. Accordingly, the federal response to labor market problems has encompassed a wide range of initiatives. These include preparing people for work (through skills training, the Job Corps, work experience programs); improving the functioning of the labor market (through matching workers with jobs, establishing a minimum wage, and the Targeted Jobs Tax Credit program); and preventing discrimination. Unresolved issues in these areas are examined. They include who should be targeted for federal assistance, which levels of government can best operate programs, how public versus private efforts should be balanced, how limited resources should be distributed, and how the welfare versus work question should be resolved. 相似文献

Observations of high velocity bloodspatter on adjacent objects 总被引:1,自引:0,他引:1
In a recent homicide investigation, high velocity backspatter was observed on the sleeve cuff of the accused. These minute droplets were discovered only after microscopic examination and were limited in number. A study was initiated to determine if these were truly backspatter droplets or transferred blood produced from light contact with a bloody item. It was observed that the backspattered blood was primarily limited to contact or near contact shots. An exception was a shot into an already bloody surface. It was found that backspattered blood would deposit on the shooter's shirt sleeve irrespective of the weave pattern. Transferred blood was observed only on the fiber tops. This information was found to be useful in reconstruction of events in suicides as well as possible homicides. 相似文献
