Human cannibal cases are relatively rare in modern civilized societies. We report a single case of familial cannibalism that occurred in Oklahoma in 1977. The investigation posed unique problems in pathology, psychiatry, criminalistics, and serology.  相似文献

This paper describes the monitored outpatient treatment program for Psychiatry Security Review Board (PSRB) clients in the largest single community treatment agency in the Oregon system. We describe 161 persons referred to this agency for evaluation and treatment. Ninety-one PSRB clients received treatment and of this group 51% had their conditional release revoked by the PSRB. The most frequent cause of revocation was noncompliance with treatment. There were only 11 crimes committed during the study period, four of which were in the felony range. The majority of PSRB clients are chronically mentally ill persons. We discuss both the treatment approach and our results in light of a recently published research agenda for insanity acquittees.  相似文献

This study examines public opinion in Costa Rica and El Salvador regarding regional integration in Central America. Recent efforts at regional integration as well as the response of the governments of the above countries to those efforts are reviewed. Public opinion toward regional integration is significantly more positive but less structured in El Salvador than in Costa Rica. Differences in the international and domestic contexts help to explain the differential responses in these two countries. Likewise, contextual factors help to account for differences between Central American and European publics in attitudes toward regional integration. Charles L. Davis is associate professor of political science at the University of Kentucky. His interests are Latin American politics and comparative political behavior. Matthew J. Gabel is assistant professor of political science at the University of Kentucky. His interests are European politics and the politics of regional integration. Kenneth M. Coleman is a former professor at the University of Kentucky, the University of North Carolina-Chapel Hill, and the University of New Mexico. His interests are Latin American politics and public opinion.  相似文献

The principal aim of our study is to contribute to the debate over whether regulation is enacted in the interest of consumers, producers, political agents, or some combination of these. We examine the legislative debates and subsequent regulatory bills surrounding road transportation regulation in Ireland in light of the three dominant theories which purport to explain the existence of regulation: the public interest theory and the so-called Chicago and Virginia theories. A unique feature of our study is an attempt to integrate specific rhetorical concepts used in the public policy debates into the theoretical analysis of regulation. One noteworthy conclusion of our study is that theories of economic processes affect the shaping and results of public policy.  相似文献

Demographic and trend analysis of 881 consecutive suicides in blacks and whites is presented. For the years 1975 through 1984, the suicide rate was 15.1/100 000 and did not significantly change. White males were overrepresented in all age groups, had an overall suicide rate of 34.9, and showed a small but statistically significant increase in rate which was not accounted for by any specific age group. White females, in general, were represented in proportion to their prevalence in the population, and those ages 20 to 24 demonstrated an increasing suicide rate which was small. Black males were at highest risk in their twenties, showed no significant trends, and were also represented near their prevalence in the population. Black females of all ages were underrepresented, and had low suicide rates which decreased with time. No significant rate changes were noted for teenagers or the elderly. Firearms was the method of choice in all groups, although methods varied with age, race, and sex, and male children preferred hanging. Small but significant increases were noted for the prevalence of nondrug methods in females and carbon monoxide deaths in white males. Similarities and differences to larger scale studies are discussed. Suicide may have characteristics unique to given geographical areas and pervasive to all areas. The authors advocate study and publication of local data to clarify further the nature of suicide.  相似文献
