Migrant labor and sexually transmitted disease: AIDS in Africa

Acquired immune deficiency syndrome (AIDS) is worldwide, but the clinical and epidemiological pattern of the disease in Africa is different from that in developed areas. "Type 1 AIDS" occurs in industrialized North America and Europe; it has a distinctive sex ratio (16:1) and risk pattern of IV drug use and sexual practices. "Type 2 AIDS" occurs in Third World countries, particularly in eastern, southern, and central Africa. It is characterized by an entirely different sex ratio (1:1) and by distinctively different risk patterns. Both epidemics are caused by the HIV-1 virus. The key concept for understanding the origins of the differences between Type 1 and Type 2 AIDS is the migratory labor system in eastern, central, and southern Africa. This system causes long absences, increased family breakdown, and increased numbers of sexual partners. Historically the organization of this labor market has created a population which suffers from epidemics of sexually transmitted diseases. These historical patterns are presented as evidence for the contemporary transmission of AIDS. When contemporary AIDS and HIV-1 seropositivity prevalence data are examined, a systematic temporal and geographic pattern emerges for the AIDS epidemic in Africa. Despite a paucity of good data, the prevalence data from eastern, central, and southern Africa support the thesis of migrant labor's role in the transmission of AIDS.     

Unintended Consequences of Land Rights Reform: The Case of the 1998 Uganda Land Act

Empirical studies of land rights privatisation have tended to underemphasise the unintended impacts of land rights reform relative to establishing whether the predicted impacts have occurred. This article, in reviewing some of the unintended consequences of the 1998 Uganda Land Act, draws attention to ways in which intended impacts may be undercut by lack of both consultation and foresight in anticipating responses to new legal provisions and by lack of adequate resourcing of the reform process. It also recognises that unintended outcomes may sometimes reflect appropriate adaptations of legal provisions at the local level, and briefly considers what light the Ugandan experience can throw on recent proposals for Normalisation of informal property rights in the Third World.     

Are Conventional Farmers Conventional? Analysis of the Environmental Orientations of Conventional New Zealand Farmers*

Abstract Within the political economy of agriculture and agrofood literatures there are examples of approaches that reject simple dichotomies between alternatives and the mainstream. In line with such approaches, we challenge the assumption that alternative agriculture, and its attendant improved environmental practices, alternative management styles, less intensive approaches, and better approaches to animal and ecosystem welfare, is the only source of agricultural sustainability. This article uses national farm‐survey results for New Zealand's sheep and beef, dairy, and horticulture sectors to examine conventional farmers, measure their assessments of farming practices, and assess their environmental orientation. Analysis identifies a proenvironmental cluster of farmers in each sector characterized by a higher environmental‐orientation score and distinct ratings of other farm practices queried in the survey. We interpret the results in terms of the exposure of different agricultural sectors to the effects of market‐based, audited, best‐practice schemes. The presence of shades of “greenness” among conventional farmers has important implications for environmental management and for our understanding of the various and complex pathways toward the greening of agrofood systems.     

No safety net for disabled children in residential institutions in Ireland

The voices of adults and children with disabilities who have experienced violence and abuse are slowly beginning to surface in the public domain. Segregated residential institutions run by religious congregations appear to be dangerous places for children with disabilities and perceived differences – according to the former residents, speaking and communicating to us today as adults in Ireland. A statutory Commission to Inquire into Child Abuse in Ireland attracted important numbers of former residents – witnesses – who recounted appalling experiences of violence as children. The UN Convention on the Rights of Persons with Disabilities contains articles concerning the prevention of cruelty, sexual assault, violence and acts of humiliation that may be useful for countries like Ireland which have been unable to ratify the Convention. The protection of children with disabilities requires legal reform in Ireland, statutory licensing, monitoring and inspection of the segregated centres where children with disabilities are living.     

The probability integral for a bivariate generalization of the non-central t

An expression for the probability integral of a bivariate generalization of the non-central t distribution is derived. This expression is then used to construct tables for various combinations of parameter values     

Family Structure and Educational Attainment: Sex Differences among Urban Blacks

Abstract

This research evaluates the impact of family structure on the educational attainment of northern urban blacks. Separate analyses of male and female adults reveal little support for the traditional view that the “broken home” lowers the achievement of black males. Rather, we find it is black females, especially in segregated contexts, who have been most adversely affected by parental absence. These findings are interpreted as reflecting the different relationship of males and females to the family under conditions of structurally-induced poverty.
