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

This article examines the impact of the Human Rights Act on the government's constitutional proposals for reform of the role of the Lord Chancellor and the appointment of the judiciary. It also looks at the uncertain acceptance of a 'human rights' culture by the department charged with lead responsibility for its implementation. It concludes that the government went further than was required in reforming the role of the Lord Chancellor. As a consequence, considerable - and possibly undue – weight now hangs on the enlarged role of the Lord Chief Justice. Meanwhile, the Department of Constitutional Affairs and its ministers have rejected the 'rule of law' brief of the Lord Chancellor without clarity as to where such responsibilities might now be adequately located within government. 相似文献

Environmental liability and harmonization in the presence of transboundary effects and hidden assets
Henry van Egteren R. Todd Smith Andrew Eckert 《European Journal of Law and Economics》2006,22(2):143-163
Within the context of transboundary disputes, this paper seeks to determine which liability concept, negligence or strict
liability, performs better when assets are secure against foreign claims for transboundary damages. Our results indicate that,
if assets are hidden from foreign claims, strict liability will not implement the socially optimal outcome, but neither will
negligence. However, even though the socially optimal outcome is not always achieved, strict liability weakly dominates negligence.
These results suggest that the harmonization of statues that deal with transboundary pollution should be based on strict liability
not negligence.

This study examined crime and violence against abortion clinics, testing elements of several theories that may help explain the variation of such attacks. The study theoretically and methodologically improved upon the prior research on abortion-related crime and violence. Theoretically, it investigated previously unexamined hypotheses from the social movement literature that may be relevant to this type of behavior. Methodologically, it used more careful measures for several variables, employed unique and heretofore ignored data bases, and examined hundreds of criminal acts across several types of crime (e.g., violence, vandalism, and harassment) directed at abortion clinics. Employing robust logistic regression and correcting for clustering of clinics by state, the study investigated the cross-sectional effects of state-level cultural and structural characteristics on anti-abortion crimes against clinics and staff. Results indicated that some crimes against clinics are more likely in areas where female empowerment is weaker, female victimization is more tolerated, and the anti-abortion movement has failed to reduce abortions. 相似文献

The public's perception of the police is important because it is linked to several important outcomes, including compliance and cooperation with police. Long recognized as being important, research has investigated the factors associated with citizens' evaluations of the police. The way police do their jobs, in addition to what they accomplish, has recently emerged as being a significant determinant of citizens' evaluations of police. What remains largely unexamined is whether this relationship varies across distinct types of contacts between the police and citizens. The current study estimated the effects of citizens' perceptions of procedural justice on overall ratings of officer performance across three types of police–citizen encounters. Results showed that procedurally fair treatment is the most important predictor of citizens' evaluations. 相似文献

This study used data from 299 police officers from 12 municipal police departments across the state of Virginia to determine
the relationship between education and police performance. Performance was measured by supervisor evaluations of each officer's
overall performance, communication skills, public relations skills, report writing skills, response to new training, decision
making ability, and commitment to the police department. Significant correlations were found between education and most measures
of performance. Most importantly, the results show a significant correlation between overall performance and education (r=24,
p.<001). The only variables not proving to be significantly related to education were objective measures of the volume of
arrests, number of times the officer required discipline, and number of accidents. Interestingly, the benefits of a college
education do not become apparent until police officers gain experience. In addition, police, officers with only a high school
diploma decreased in overall performance after five years of experience. 相似文献
