abstract: The AIDS epidemic has tremendously impacted the population of Mozambique. The rate of newly infected young women continues to grow disproportionately which is why consideration of health interventions specific to this population to combat the spread of the disease is critical. The Health Belief Model emphasizes the importance of self efficiency in the process of health related behavioral changes. Previous research has found that low levels of autonomy increase one's risk of contracting HIV/AIDS. This research uses data from a study conducted in 2006 in Mozambique to test whether higher levels of autonomy are associated with the practice of self protective behaviors related to the contraction of HIV/AIDS. Results suggest that some measures of autonomy such as education are positively associated with the practice of self protective behaviors. However, higher levels of decision making powers were negatively associated with the practice of self protective behaviors. / Dissertation/Thesis / M.A. Sociology 2011

Newspaper article: "This thorn tree, standing in the heart of Lourenco Marques business district, is reputed to be over 100 years old. Legend says it is the tree under which transport riders from the Transvaal used to outspan after the long trek to Delgoa Bay. It is also claimed as the tree under which Sir Percy Fitzpatrick and his immortal Jock camped before leaving for the interior.”

Stigma is broadly considered as an important obstacle in HIV prevention and treatment. In Mozambique, more PLWHIV have access to treatment than ever. ART increased their QoL and created a new context for stigma production. This cross-sectional study conducted in Northern Mozambique explored a possible association between stigma and QoL. The Berger Stigma Scale and WHOQOL-BREF were used to measure levels of HIV-related stigma and perceived QoL in two groups of PLWHIV receiving ARV, with participation in a HBC programme as the independent variable. The study uncovered a weak to moderate negative correlation between stigma and QoL scores. Statistically significant differences were discovered between the groups’ scores on the Berger Stigma Scale and a higher perceived QoL for PLWHIV in the HBC group on three WHOQOL-BREF subscales and on the overall score. The scores on the social relationships subscale indicated lower perceived QoL for PLWHIV in the HBC group. / Sociology / M.A. (Social Behaviour Studies in HIV/AIDS)

M.Sc. / Aquatic toxicology is the qualitative and quantitative study of toxic effects of pollutants on aquatic organisms. The main goal in toxicity testing is to predict, in combination with other environmental factors, with known accuracy, a concentration of a specific toxicant that will not harm a system and to make this prediction in a responsible and cost effective manner. There are a variety of unique toxicity tests, with fish being one of the most popular organisms to work with, due to being the best-understood organism in the aquatic environment and its commercial importance. Zinc, copper and cadmium are three biologically important heavy metals that are commonly used in various industries. Low concentrations zinc and copper are essential micronutrients for both plants and animals, but in higher concentrations they become toxic to the environment and its biota. Cadmium has a chemical structure similar to that of zinc and is often found in association with it, but it is a very toxic substance. The effects of zinc, copper and cadmium on the free-embryo life stage (yolk sac phase) of Oreochromis mossambicus were examined, for evaluation as a possible ¡§early life stage¡¨ fish lethality assessment. ¡§Fish early life stage tests¡¨ are considered to be relatively quick, comparable and inexpensive screening tools for testing effluents and chemicals. The yolk-sac stage is considered the most sensitive life stage in fish. O. mossambicus free-embryos feed endogenously and are indigenous to southern Africa and are therefore a good choice for lethality testing. The effects of the same metals on randomly selected Culicidae (mosquito) larvae were also tested. The reason for randomly selected larvae was to determine the possibility of doing toxicity testing without a species-specific culture. Mosquitoes are very common and well known due to being vectors of various human diseases. Recommendations towards future studies, to determine the usefulness of both O. mossambicus embryos and Culicidae larvae as biological indicator organisms, were also looked at. / Prof. G.J. Steyn
