Toxicologic findings in the USS Iowa disaster. 总被引:5,自引:0,他引:5
The toxicologic results from the 47 victims of the explosion on the USS Iowa are presented. Good correlation between carboxyhemoglobin saturations and cause of death was found. There were no correlations between blood cyanide concentrations and causes of death. Volatile analysis suggested postmortem ethanol production rather than antemortem ethanol ingestion. No drugs except nicotine were detected in any of the victims. 相似文献

A 6-month-old girl died suddenly without any previous symptoms of heart failure. Autopsy examination showed cardiomegaly (97 g) with a severely fibrotized myocardium. The left coronary artery was originating from the pulmonary artery. Histologically, the myocardium showed myocardial infarcts of different ages, as well as grossly thickened arterial branches due to increased flow in left-right shunt. We suggest that rare anomalies of the coronary arteries should be considered in the autopsies of suspected sudden infant death syndrome cases. 相似文献

The impact of high temperatures (24 to 39 degrees C) and low to moderately high humidities (20 to 70%) on the applicability of TLC systems for drug identification was studied during a 6 month climatologic cycle in Burkina Faso (West Africa). In general, the Rf values as observed on the plates were found to be substantially affected as compared with values obtained at temperate climates. Some TLC systems were more affected than others and the largest deviations of up to 30 Rf units were at low humidities. Tropical conditions also had a negative effect on the reproducibility of Rf values. However, when an Rf-correction procedure was applied, using reference mixtures of known drugs on each plate, accuracy as well as reproducibility of the resulting Rfc values were drastically improved and data thus corrected were found to be compatible with existing TLC data bases developed under moderate climatological conditions. The impact of high to extremely high humidities (70 to 100%) remains to be investigated. 相似文献

Many attempts have been made over the last several decades to improve communication among law enforcement agencies. This article
is a case study of a “low-level” data sharing project in Florida that could serve as a national model. The Florida Law Enforcement
Data Sharing Consortium is a partnership between the University of Central Florida and more than one hundred law enforcement
agencies. It offers an inexpensive, yet technically advanced alternative to the proprietary data sharing model. Its distributed
architecture was endorsed by the Markle Foundation, the 9/11 Commission, and the 2004 National Security Act. Civil liberties
concerns raised by this and other types of data sharing projects are discussed. 相似文献

Experiencing a criminal victimization is among one of the most stressful human experiences. A cross-sectional study of victims of violent crime and victims of nonviolent crime suggests that there are statistically significant differences in experiences in the initial aftermath of the crime event and a few common effects. This article describes the common effects that are associated with criminal victimization in the context of intense distress and discusses the theoretical implications of well-being in the coping process. One hundred seventy-five victims of violent or nonviolent crime were interviewed. Implications for social work practice and theory and future research are delineated. 相似文献

U.S. Supreme Court Justice Thurgood Marshall offered his opinion regarding the utility of public opinion polls as a tool for assessing the “evolving standards of decency” regarding capital punishment. His arguments became known as the Marshall hypotheses and spawned a considerable body of empirical testing. The three Marshall hypotheses are: (1) support for capital punishment is inversely associated with knowledge about it, (2) exposure to information about capital punishment produces sentiments in opposition to capital punishment, but (3) exposure to information about capital punishment will have no impact on those who support it for retributive reasons. The results of previous tests of these hypotheses were somewhat mixed but supportive. None of these studies, however, examined the effects of change in knowledge levels with changes, if any, in death penalty attitudes and beliefs as needed for a more complete test of the Marshall hypotheses. The present study addressed this shortcoming. The results provided mixed support for these three hypotheses. That is, death penalty supporters were somewhat less informed than death penalty opponents; exposure to death penalty information and knowledge gains tended to be associated with attitudinal change in a directions suggested by these hypotheses; but, retributivists' attitudes toward and beliefs about capital punishment were not any more resistant to change than were the attitudes and beliefs of non-retributivists. 相似文献

Fair Trade has become a dynamic and successful dimension of an emerging counter-tendency to the neo-liberal globalisation regime. This study explores some of the dilemmas facing the Fair Trade movement as it seeks to broaden and deepen its impact among the rural poor of Latin America's coffee sector. We argue that the efforts to broaden Fair Trade's economic impact among poor, small-scale producers are creating challenges for deepening the political impact of a movement that is based on social justice and environmental sustainability. The study is based on two years' research and seven case studies of Mexican and Central American small-scale farmer cooperatives producing coffee for the Fair Trade market. 相似文献
