Food is one of the main routes by which xenobiotic (synthetic) chemicals enter the body of man and wildlife. The routes could be from wrappers in which the foods are presented with possible transfer of the compounds to consumers, hence need for regular screening. The research work is aimed at investigating possible prevalence of phthalate esters in selected foods (cheese, polony and vienna) and their plastic wrappers from commercial stores in Tshwane metropolis. Food samples were purchased from selected stores, taken to the laboratory and stored at 4oC until analysed. Analysis was done by soxhlet extraction while determination and quantification of phthalates was carried out using Gas Chromatography-Flame Ionization Detection (GC-FID). Quality assurance of the process was by standard addition of the phthalate ester standards. Results obtained revealed good chromatographic separation of the analysed esters which ranged from 5.55 min for Dimethyl phthalate (DMP) to 8.96 min for Benzylbutyl phthalate (BBP). Instrumental detection limit of the esters varied from 0.03 - 0.05 μg/kg. The percentage recovery of the phthalate esters ranged from 75 – 90% from spiked cheese samples; 33 – 66% from spiked polony samples and 69 – 99% from spiked vienna samples. These recoveries are quite acceptable and applicable to the analysis and quantification of the compounds in the samples with the exception of Dibutyl phthalate (DBP) (33%); DMP (34%) and BBP (46 %) in polony samples. Results from chromatographic quantification revealed the absence of or non-detection of most of the analysed phthalate esters in the selected food samples. However, level of 0.031 μg/kg of BBP - 0.816 μg/kg of DMP were obtained in some of the analysed samples. / Environmental Sciences / M. Sc. (Environmental Science)

In South African Law, sex work is currently mainly dealt with in terms of the Sexual Offences and Related Matters Act 32 of 2007, although other legislation, such as the Aliens Control Act 3 of 1993 also contains provisions that are peripherally relevant to sex work. In addition, municipal by-laws play an important role in the regulation of sex work, especially outdoor sex work. These by-laws are often aimed at addressing the more visible aspects of outdoor sex work. This dissertation aims to analyse the policing methods used by the police when policing sex work in Sunnyside, and whether the police have the ability and capacity to enforce current legislation in this regard. The enormous incidents of dehumanization and abuse of sex workers by the police who are supposed to enforce the Sexual Offences Act 32 of 2007 and the previous legislation on sex work questions whether the police should be given more or less powers in dealing with this crime. This dissertation aims to conduct an in-depth analysis of relevant literature in order to provide a background for the discussion on the origins of sex work and the different legal models for dealing with sex work. The study also endeavours to establish a frame of reference for considering different legal models to deal with sex work and to identify different policies and legal approaches to sex work, and to consider the impact of the current laws regulating sex workers and the harm that result from this. The dissertation aims to explore and describe the challenges that the police in Sunnyside experience, and also to analyse the difficulties that sex workers often encounter. The knowledge generated in this study will enhance the existing knowledge in the policing of sex work, and will also serve to educate the police, criminal justice institutions, and the community about the nature and extent of the problems that policing agencies experience when policing sex workers in Sunnyside. / Police Practice / M.

Text in Afrikaans / The researchers' own interaction with the community caused her to recognize that the safety of pre-schoolers and toddlers in high risk areas are being jeopardised because sexual education is not applied soon enough. The aim of this research study was to determine the needs of role-players in the high risk area in terms of community education regarding the safety of pre-schoolers. A quantitative approach was followed, which focussed on applied research and the exploratory and descriptive objectives of the research in order to facilitate a better understanding of the research phenomenon and to understand the specifics of the situation. The Randomised Cross-sectional Survey design was implemented. The analysed findings were presented graphically and interpreted in order to reach conclusions and present the recommendations of the study. The general conclusion based upon the empirical findings of the study is that there is a great need for community education regarding the safety of pre-schoolers in the high-risk area, Danville. / Social Work / M.

This study is a need assessment for the establishment of an HIV and AIDS support group within the South African Police Services (SAPS), Head Office Divisions and the purpose was to explore the extent to which an HIV and AIDS support group was needed for HIV and AIDS-infected and affected personnel within the South African Police Services (SAPS). The SAPS employees as well as HIV and AIDS programme managers participated in the study. A combination of quantitative and qualitative data was used in the study. The former was obtained from a survey of 90 SAPS personnel based at the SAPS Head Office Divisions in Pretoria. The latter, on the other hand, was obtained from in-depth interviews with five SAPS HIV and AIDS programme managers, also based at Head Office Divisions in Pretoria.The overall results showed that an internal workplace HIV and AIDS support group for infected and affected employees was seen as necessary to deal with the psycho-social and emotional needs of the personnel. The study participants were generally of the view that such a support group would go a long way in addressing some of the challenges and obstacles – such as stigma, discrimination, judgement and so forth – faced by HIV and AIDS-infected and faced employees within the SAPS. In general, it was envisaged that a workplace support group would create a warm and caring environment that would enable employees to feel safe and supported by their colleagues – including commanders and managers – in dealing with their HIV and AIDS situations. / Health Studies / M.A. (Social Behaviour Studies in HIV and AIDS)

Women face a greater risk of HIV infection worldwide than men. This study explored socio-economic, cultural and environmental factors influencing young women’s vulnerability to HIV. A quantitative explorative study was conducted among young women in Sunnyside, Pretoria. A sample of 158 young women in the age group 18 to 24 years from all language groups was randomly selected to participate in this study. The findings showed that poverty, peer pressure and multiple sexual partners were the main factors that influenced young women in Sunnyside’s vulnerability to HIV. Behavioural change and social change were recommended as long-term processes, which need to be taken into consideration. Findings from the Sexual Relationship Power Scales show that young women between 18 and 21 years experience physical abuse, emotional abuse, sexual abuse and forced sex in their relationships. The study concluded with specific recommendations for the successful implementation of policy makers and planners to protect women. / Health Studies / M.A. (Social Behaviour Studies in HIV/AIDS)

The positive role and fundamental contribution of entrepreneurship on a global and national level is an unconditional phenomenon pertaining to economic growth. There are though various perspectives and opinions on the format and context of contribution. One of these perspectives embraces the obstacles involved in the entrepreneurial process hindering contribution and economic catalisation. This study follows a focused approach towards investigating a critical obstacle and specifically the access to finance, within an indicated geographical area. The research intervention has obtained a large and reliable data set to examine the contention that there are obstacles faced by entrepreneurs in accessing small business finance in the Tshwane area. The findings of the study support this contention and also the fact that conventional financing mechanisms do not allow for cost-effective provision of finance to large numbers of entrepreneurs seeking small quantities of finance. Poverty and lack of assets mean that many people do not have the collateral needed to access formal financing. / Business Management / M. Comm. (Business Management)

This study focuses on the psycho-social challenges faced by HIV/AIDS lay counsellors at a Voluntary Counselling and Testing (VCT) site in Tshwane, South Africa. A qualitative approach was employed by using semi-structured interviews with open-ended questions to obtain information from four lay counsellors, who provide pre- and post-test counselling at a VCT site. The results indicate that the management of clients’ emotions and needs pose enormous challenges to HIV/AIDS lay counsellors who do not receive any formal psycho-social support at VCT sites. The research participants in this study resort to their own coping mechanisms to deal with the challenges – with varying degrees of success. The recommendation is made that a formal support programme should be put in place at VCT sites, which will allow HIV/AIDS lay counsellors to respond to the many demands placed on them. Such a programme can help prevent burnout and a high turnover in lay counsellors. / Social Work / M. A. (Social Behaviour Studies in HIV/AIDS)
