Sexual Violence and HIV/AIDS in Sub-Saharan Africa: An Intimate Link

Sexual violence is an epidemic that often overlaps with the AIDS pandemic and is often a cause and consequence of the spread of HIV/AIDS amongst women and girls. Presently, half or more of the 40 million people infected with HIV in the world are women. Millions of those infected are aged 15-24 years and have suffered some form of intimate partner violence. This group accounts for half of all new infections. In sub-Saharan Africa, young women account for 75% of HIV infections and are approximately two-and-a-half times more likely to be infected than young men of the same age (UNAIDS, Report on the Global AIDS Epidemic: 4th Global Report, Geneva, 2004). What makes women, especially girls and younger women, so disproportionately vulnerable to HIV infection, and why have current AIDS control efforts in sub-Saharan Africa largely failed to stem the epidemic in this gender?     

Assessment of physico-chemical properties and metal contents of water and sediments of Bodo Creek,Niger Delta,Nigeria

Some physico-chemical properties and the concentrations of the metals Fe, Mn, Ni, Cd, Cr, Co, Cu, Pb, and Zn in water and sediments were examined from September 2011 to January 2012 in Bodo Creek, where oil spills have been recurrent. Temperature, pH, total dissolved solid, conductivity, salinity, dissolved oxygen, biological oxygen demand (BOD), chemical oxygen demand (COD), total hardness, sulfate, nitrate, and phosphate were determined in surface water. Particle size, total organic matter (TOM), and pH were also determined in the sediments. The parameters were within permissible limits except the mean values of BOD, COD, total hardness, and sulfate that exceeded levels permissible for domestic use. The sediments consisted mainly of sand, with TOM ranging from 0.2% to 5.5%. With the exception of cadmium that was below detection limit, metal levels (mg kg^?1) in the sediments were 12 (Mn), 1070 (Fe), 10 (Cu), 10 (Zn), 5.3 (Cr), 1.1 (Pb), 1.0 (Ni), and 0.5 (Co) while in water they were 24, 98, 21, 6.9, 4.0, 0.6, 0.18, and 0.16, respectively. The latter were higher than World Health Organization recommended permissible levels for both surface and drinking water.     

Health sector reform in Nigeria: A perspective on human rights and gender issues

Public health and human rights are complementary approaches to promoting and protecting human dignity and well-being. The aim of this paper is to examine international provisions and national policies on health and human rights that regulate the health system in Nigeria, along with the institutional arrangements created for the design and implementation of health services. The paper reviews the framework for policy formulation and planning on health matters and emphasizes the responsibilities of the state to implement Millennium Development Goals and international obligations of human rights. It highlights the importance and impact of gender and reproductive rights on health system performance and concludes by proposing legal strategies to improve health outcomes in the country.     

Sexual Violence and HIV/AIDS in Sub-Saharan Africa: An Intimate Link

Abstract

This paper critically examines how privatisation and liberalisation of electricity provision is reconstructing energy consumption practices. The paper discusses the commercial restructuring of the electricity industry in the UK over the last four years, illustrating how a reconfiguration of production and consumption interests is transforming the utility marketplace: differentiating the value of resource units, distinguishing between infrastructure suppliers and stratifying utility customers. This process is shown to be resulting in differential forms of service provision as utility companies actively engage with more lucrative customers, presenting opportunities for environmental innovation, while disengaging from unprofitable customers and heightening social polarisation.     

Effect of chronic exposure to drilling fluid XP-07 on gonad histology in Tilapia guineensis

Changes in Tilapia guineensis gonads exposed for 12 weeks to XP-07 at a concentration of 2.5, 1.25, 0.63, or 0.32% were investigated using a static renewal method. The histological changes noted in the gonads of the exposed fish were inhibition of maturation in oocytes or spermatogenesis. In contrast, the four stages of sperm or ova development were present in the control fish and spawning occurred. The increasing degeneration (artesia) of maturing egg resulted in complete absence of matured eggs in the female gonads of fish exposed to highest concentration (2.5%) of drilling fluid. The gonadal somatic index (GSI) values were recorded in a decreasing order towards the higher tested concentrations. The GSI values ranged from 3.11 to 1.47% in females and from 0.42 to 0.16% in males, whereas in control, it was 3.18% for females and 0.52% for males. Data showed that XP-07 exerted adverse effects on reproductive processes, which led to impairment in the reproductive success of T. guineensis.
