Thesis (M.Sc.(Med.))--University of the Witwatersrand, Faculty of Health Sciences, 2012. / Neurodevelopmental delay has been documented in up to 97.5% ofHIV-infected childfen in Soweto who were not yet on ART. With growing numbers of children in South Africa being successfully treated with antiretroviral treatment (ART), the effects of ART on neurocognitive functioning in children require investigation. The objective of this study was to determine the extent of neurodevelopmental delay in stable HIV -infected preschool children (aged) 5-6 years) receiving ART and compare it to an apparently healthy . (unconfirmed HIV-status) group of preschool children. Thirty HIV-infected preschool children (virologically and immunologically stable on ART for> 1 year) were conveniently sampled from 350 eligible children on ART at the Harriet Shezi Children's Clinic in Soweto, Johannesburg. The comparison group comprised thirty well-nourished preschool children attending the Lilian Ngoyi Primary Health Care Clinic in Soweto for routine immunisations. Each child was assessed using the Griffiths Mental Development Scales-Extended Revised Version (GMDS-ER), at a single point in time. The overall developmental z-scores on GMDS-ER were <-2 (indicating severe delay) in 27 (90%) children in the HIV-infected group compared to 23 (76%) in the comparison group (p=0.166). Mental handicap (overall GQ<70) was evident in 46.7% of children in the HIV -infected group compared to 10% in the comparison group (p= 0.002). There was a 7.88-fold increased likelihood of severe delay in the HIV infected group. The HIV -infected group and comparison group had significantly different (p=0.001) mean overall GQ scores of70 (95% CI: 66.0-74.0) and 78 (95% CI: 75.6- 80.5), respectively, with lower mean scores in the HIV -infected group in all individual domains. Early initiation of ART in HIV-infected infants may improve cognitive functioning among this group, however, intervention strategies which optimize early cognitive development for all children in the area, need to be urgently considered.

Economic events may cause structural changes in markets. To know the effect of the economic event we should analyze the structural changes in the market demand and supply. The purpose of this dissertation is to analyze the effect of selected economic events on market demand and supply using econometric models. Structural changes can be modeled according to the types of changes. For an abrupt and instantaneous break, a dummy variable model can be used. For a smooth and gradual movement, proxy variables which represent the event can be applied, if we know the variables. If we don‟t know the appropriate proxy variables, a smooth transition regression model can be employed. The BSE (Bovine Spongiform Encephalopathy) outbreak in the U.S. in 2003 is assumed to make abrupt and instantaneous changes in Korean meat consumption. To analyze the effect on Korean meat consumption, the Korean demands of beef, pork, chicken, and U.S. beef are estimated using an LA/AIDS (Linear Approximate Almost Ideal Demand System) model with the dummy variable specifying the time before and after the BSE. From the results we can confirm that food safety concerns caused by the BSE case changed Korean meat consumption structure. Korean beef and U.S. beef became less elastic, and pork and chicken got more elastic to budget. Korean beef became less price elastic, but pork and U.S. beef got more price elastic. The changes of U.S. natural gas supply caused by technology development and depletion in reserves are analyzed using a smooth transition regression model. From the results, we can confirm that the productivity improvement by technology development is greater than the labor cost increase by depletion, but not greater than the capital cost increase by depletion in mid-2000s. The effects of posting the winning bid in a repeated Vickrey auction are examined using a proxy variable. By applying an unobserved effect Tobit model to the experimental auction done by Corrigan and Rousu (2006) for a candy bar, we can confirm that the changes of bidding behavior are significant, especially when the winning bid is high. By extracting the bid affiliation effects, we showed that true willingness to pay can be estimated.
