Human immunodeficiency virus infection in cases presenting to the Philadelphia Medical Examiner's Office.

Serum samples were available from 492 of 1,058 cadavers seen at the Philadelphia Medical Examiner's Office between August 4 and December 15, 1989. These sera were tested for the presence of antibodies to human immunodeficiency virus (HIV) by enzyme-linked immunosorbent assay (ELISA) and Western blot. The overall prevalence of HIV in the autopsy population was 2.24%. The following populations showed increased prevalence as compared to the total sampled population: blacks (3.60%, p less than 0.01), males (2.51%, n.s.), and homicide victims (3.74%, n.s.). Seroprevalence data from this study are compared with those from earlier studies of other related populations, with regard to overall prevalence and risk factor analysis.     

The one-third rule: Learning about the net economic benefit of a subsidy from a single observation

The subsidization of a natural monopoly is justified on welfare-economic grounds if the resulting total economic surplus exceeds total costs. Using rather standard assumptions, a simple check, managing with a minimum of information and, in particular, without virtually any knowledge of the demand curve, is developed which is capable of confirming an existing economic case for subsidization.     

STRUCTURAL INEQUALITY AND HOMICIDE: AN ASSESSMENT OF THE BLACK‐WHITE GAP IN KILLINGS*

This paper examines the relationship between race and violent crime by directly modeling the racial gap in homicide offending for large central cities for 1990. We evaluate the role of black‐white differences in aspects of both disadvantage and resources in explaining which places have wider racial disparities in lethal violence. The results show that where residential segregation is higher, and where whites' levels of homeownership, median income, college graduation, and professional workers exceed those for blacks to a greater degree, African Americans have much higher levels of homicide offending than whites. Based on these results, we conclude that the racial homicide gap is better explained by the greater resources that exist among whites than by the higher levels of disadvantage among blacks.     

Changing security cultures in Europe and Southeast Asia: Implications for inter-regionalism

Recent development in Southeast Asia demonstrates a slowly but steadily changing security culture from, first, an informal, consensus-based and often hidden way of managing security to a more open and explicit discourse and, second, from a statist realist definition of security as hard or military security to a broader, liberal understanding that covers the whole spectrum of human, economic and environmental security. This security culture in the making also touches upon formerly tabooed issues such as sovereignty and humanitarian intervention. The paper argues that the new approach has removed obstacles in relations between Europe and East Asia and contributed to the emergence of security as a cornerstone of the co-operation agenda since 1998. At the same time, however, a rapid translation of the inter-regional discourse on security into a working programme or even specific policies is hindered by the prevalence of diverging views on the nature, scope and degree of institutionalisation in Europe-East Asia relations.     

Zimbabwe black population data on the six short tandem repeat loci – CSF1PO, TPOX, THO1, D3S1358, VWA and FGA

Allele frequencies for six tetrameric short tandem repeat (STR) loci CSF1PO, TPOX, THO1, D3S1358, VWA, and FGA were determined in a Black African sample population from Zimbabwe. All loci are highly polymorphic and meet Hardy-Weinberg expectations. An inter-class correlation test analysis detected only one departure from independence out of 15 pair-wise comparisons of the six loci (i.e., CSF1PO/VWA loci, P=0.026). The allele frequency data at four of the six STR loci in the Black African sample population are similar to African American data.
