The sexual abuse of children has become recognised as a major problem affecting children in most, if not all, countries of the world. The prevention of such abuse has, in the last decade, become an issue of international significance. In South Africa, prevention efforts are mainly informal ad hoc strategies initiated by individuals or organisations. As such they suffer from being short-lived and often isolated. Prevention efforts fall into the general categories of primary, secondary and tertiary prevention. Primary prevention focuses on preventing abuse from occurring at all. There are two main aspects to this type of prevention. The first aims at teaching children to protect themselves. The second aims at preventing the development of a disposition to abuse. This study set out to suggest and justify the adoption of a national strategy appropriate to the South African situation, including an overview of what can be done through the schooling system. This strategy will provide a framework and context for individual efforts, and hopefully stimulate new programmes. In addition, a detailed prevention programme for implementation in the secondary school, through the medium of the subject Guidance, was developed. This programme addressed itself mainly to that primary aspect of prevention concerned with preventing people from developing a disposition to abuse. The programme consists of lesson plans, teacher's notes and worksheet materials for pupils.

Text in Afrikaans / Die aard en omvang van motorvoertuigdiefstal in Suid-Afrika, het die ondersoeker aangespoor om 'n studie van die verskynsel soos dit in die Pretoria-Sentraal polisiestasiegebied voorkom, te loods. Data wat uit die dokumentere studie van gebeure ingesamel is, is rekenkundig gekwantifiseer en het besondere misdaadpatrone wat betrekking het op motordiefstal aan die lig gebring. Dit het tot die formulering van 'n multidissiplinere misdaadvoorkomingsbestuursmodel bygedra. Vanwee die erns van die verskynsel en die ekonomiese implikasies wat dit meebring, moet daar op 'n voortdurende grondslag navorsing uitgevoer word ten einde metodes te verskaf om die omvang van motorvoertuigdiefstal te verminder. Die owerheid moet 'n belangrike rol speel in die oplossing van die probleem. / The nature and extent of motorvehicle theft in South Africa encouraged the researcher to pilot a study into the phenomenon as it manifests itself at the Pretoria-Central police station area. Data gathered, in a documentary study of events, has been arithmetically quantified and reveal particular crime patterns relating to motorcar theft. This contributed to the formulation of a multidisciplinary crime prevention management model. Due to the seriousness of the phenomenon and the economic implications it causes, in depth research needs to be undertaken on a continuous basis to establish means to reduce the extent of motorvehicle theft. The authorities should play an important role in resolving the problem. / Criminology and Security Science / M.A. (Kriminologie)

Assessment tools have been used for various purposes, including for protecting children from maltreatment. The main aim of this study was to to evaluate and determine the relevance of the Family Assessment for Leased Developed Countries (FALDC) assessment tool for child protection services in the Eastern Cape Province. The research was conducted using the social developmental welfare approach (Patel, 2005) and ecological systems theory (Healy, 2005). The study made use of the qualitative research method; in doing so the study made use of the case study design. In using the qualitative research method, focus group discussions were conducted with 29 social workers involved in child protection services. The findings of the study indicated that the FALDC assessment tool provides information useful for child protection services even though it contains sections that are regarded as less relevant to child protection. The study also founded that the FALDC assessment tool is relevant to child protection in the South African context, yet it needs to be aligned so that it provides much of the information desired by those involved in child protection. A conclusion drawn from this study is that the FALDC assessment tool appears to be relevant for child protection services. The FALDC assessment tool needs to be adjusted taking into consideration other aspects important to child protection in the South African child protection context.

M.Phil. / Three test and certification bodies in the explosion prevention field currently exist in South Africa. One of these bodies was started in 2003 and faced a significant number of challenges in competition with the two other wellestablished bodies / institutions. This dissertation covers some of the internal and external challenges especially with respect to strategic marketing in a small and specialized industrial market, but also in the global market. The dissertation is based on the basic requirements, analysis and implementation of a marketing strategy and marketing plan, covering both the theoretical aspects and the specific challenges as experienced by the body in the case study. Market research, market segmentation, industry analysis, competitive analysis, aspects of industrial marketing and SWOT Analysis are topics included in the development of the strategic and marketing plan for the business in the case study.

The world has entered the third decade of the HIV and AIDS epidemic under different times in which the epidemic is treatable. The International Labour Organisation (ILO) (2005) declares HIV and AIDS a developmental crisis destroying developmental gains over generations. Since HIV and AIDS affect the most productive segment of the labour force, it is therefore not only a threat to development but also to the world of work without which development will be sacrificed (ILO, 2001). Collaborative response efforts that seek to mitigate the HIV pandemic by government, business and higher education institutions have been fraught with challenges. The main challenge that beset these efforts is that, in the absence of an HIV vaccine, voluntary counselling and testing remains the gateway to access treatment and care. Regrettably, participation in VCT has been confronted by challenges of low utilisation. This precedes the objectives of this study, which were to explore and describe factors that serve as barriers and facilitators of workplace VCT programmes with the objective to improve participation in these programmes. The current study was a product of a qualitative and exploratory-descriptive research design. A nonprobability convenience sampling method was used to sample participants for this study. The targeted population in this study were the non-academic employees of an academic institution in the Eastern Cape. Data was collected by means of focus group discussions and by using semi-structured interviews. The focus group samples comprised of an equal number of men and women with an overall participation of fifty-six participants. Data obtained was transcribed, thematically analysed and coded using Henning, Van Rensburg, and Smit's (2004) qualitative analysis and interpretation method. Findings of this research revealed that factors that facilitate and inhibit voluntary counselling and testing are psychosocial and cultural by nature. At psychosocial level, participants reported factors that facilitate voluntary counselling and testing to include psychological readiness to go for HIV testing, reassurances of confidentiality of HIV test results and normalising HIV testing (making the process more like that for screening and diagnostic testing). Cultural factors included cultural practices and beliefs such as "intonjane" and traditional circumcision - positive cultural nurturers that could facilitate VCT participation. Results of this study showed a lack of basic knowledge about VCT and fear of knowing one's status, fear of breach of confidentiality, fear of being stigmatised and a lack of trust towards health professional as the major psychosocial factors that serve as barriers to VCT participation. The cultural barriers to VCT pointed to hegemonic masculinity as a socially constructed gender identity that encourages gender inequalities and undermines efforts to improve HIV testing. The study suggested that strategies to increase VCT participation should consider leadership support of VCT programmes, incentivisation of VCT programmes, institutionalisation of HIV and AIDS education and the establishment of integrated wellness services for employees.

Avian influenza is an infectious disease of birds caused by the Type A strain of the influenza virus. The disease, which was first identified in Italy more than 100 years ago, occurs worldwide (World Health Organization, 2006a). The current outbreak of the highly pathogenic avian influenza A (H5N1), which began in Southeast Asia in mid-2003, is the largest and most severe on record. Never before in the recorded history of this disease have so many countries been simultaneously affected. Since the last pandemic in 1968-1969, the risk of an influenza pandemic has not been considered greater than at the present time. The importance of intervention strategies had become increasingly evident throughout the world. The World Health Organization provides a generic outline for preparedness plans to assist countries in their preparations to respond to a possible avian influenza pandemic. These guidelines may be modified as the epidemiology of avian influenza evolves. The South African National Department of Health has developed national guidelines in the form of an avian influenza preparedness plan. These draft guidelines do not provide detailed Environmental Health work methods and - procedures for the effective surveillance and control of the disease. The general purpose of this study is to develop a standardised set of Environmental Health work methods and - procedures, which will contribute to the effective surveillance and control of avian influenza in the Eastern Cape province – South Africa. Within the context of the purpose of this study, a qualitative, explorative, descriptive, inductive and deductive research design will be used. The methods of data collection will be documentary research, telephonic as well as in-depth personal interviews. In this study, documentary research will be the primary method of data collection. With a qualitative approach, the researcher will be the human instrument for data analysis. The process of qualitative data analysis will be based on data reduction and interpretation; and will be conducted as an activity simultaneously with data collection, data interpretation and narrative reporting writing.

At present there is no cure or vaccine for Human Immuno-deficiency Virus (HIV) or Acquired Immune Deficiency Syndrome (AIDS) therefore prevention programmes are seen as the only means of reducing the spread of the disease. HIV/AIDS education programmes in schools have been identified as the most effective intervention because billions of children can be reached worldwide and because schools are the one social institution with which most children come into contact. Young people in particular have been identified as the age group most in need of a preventative programme. The aim of this study is to explore the perceptions of grade six and seven learners with regard to the Life Skills programme focusing on HIV/AIDS education in the Port Elizabeth region. In order to fulfill the above aim a qualitative study was undertaken within an exploratory descriptive approach. A non-probability, convenient sample of six schools were selected. Focus groups, utilising an unstructured interview, were used to gather qualitative data about the perceptions of grade six and seven learners. The focus groups consisted of 10-12 participants. The data was thematically analysed using Tesch’s approach. The major findings of the present study included the following: 1. Learners’ perceptions of completing the questionnaire were generally positive in nature. Negative perceptions related to practical issues such as the length of the questionnaire and the time of administration. 2. Learner’s perceptions of the programme were generally positive. 3. Learners’ felt more comfortable discussing HIV/AIDS with parents and teachers. xi 4. Learners’ appeared to be well informed about high-risk behaviour related to HIV/AIDS and existing myths. 5. Contact with HIV+ people is non-existent. However, learner’s felt that the programme had fostered positive attitudes towards HIV+ people. 6. Learner’s felt that schools had an important role to play in sharing information about HIV/AIDS. These findings seem to indicate positive outcomes for the programme as a whole, in that is was successful in terms of conveying information regarding HIV/AIDS; it led to positive changes in attitudes, especially towards HIV+ people; and it confirmed the school as the best setting for implementing HIV/AIDS Life Skills programmes.

M.Sc. / The induction of heat shock proteins (HSPs) in human monocytes during a pathogen challenge is a sophisticated selective response and plays an important role in cytoprotection from inflammation-related stress, including oxidative injury. We investigated the accumulation of the inducible isoform of the 70 kDa HSP, Hsp70, in peripheral blood monocytes from 12 healthy donors in response to Mycobacterium tuberculosis (M.tb) using flow cytometry, biometabolic labeling or Western blot analysis. Cells from each donor, prepared on two different occasions, were exposed to virulent (H37Rv) and attenuated (H37Ra) strains of M.tb at two bacterium : monocyte ratios (1:1 and 10:1) for 3 h and allowed to recover for an additional 2 h or 24 h. In spite of a prominent inter-individual variation, H37Ra (1:1, 2 h) significantly induced the mean Hsp70 accumulation (p<0.05) compared to normal cells, while H37Rv (10:1, 24 h) significantly suppressed the mean Hsp70 levels (p<0.001) in monocyte compared to normal monocytes or monocytes exposed to H37Ra. Survival of H37Rv-infected monocytes showed a significant correlation with Hsp70 levels. These results suggest a protective role of Hsp70 in host defense against mycobacterial infection. Cell death due to insufficient endogenous levels of Hsp70 implies a novel pathogenic strategy for virulence of M. tuberculosis.

The aim of this study was to develop a standardised set of Environmental-Health work methods and procedures, with the purpose of contributing to the effective surveillance and control of Cholera in the KwaZulu-Natal province, South Africa. The researcher followed a qualitative research design, which was explorative, descriptive, inductive and deductive by nature. The methods of data collection were documentary research and focus-group interviews. A documentary research approach was employed as the primary method of data collection for the study. The researcher has used semi-structured questions to obtain relevant information from the participants in the focus groups. The purpose of using semi-structured questions in the focus groups was to draw on their knowledge and experience of communicable disease surveillance and control in relation to Cholera, as well as to ascertain their views on the role of the Environmental-Health Practitioners in the Communicable - Disease Outbreak- Response Teams at the three different spheres of government. The process of qualitative data analysis was followed. This was based on data reduction and interpretation; and it was conducted as an activity simultaneously with data collection, data interpretation (coding) and narrative writing. The information obtained from the analysed data assisted in the development of the environmentalhealth work methods and procedures for the surveillance and control of Cholera in the KwaZulu-Natal province, South Africa. In this study, firstly, the epidemiology of Cholera was described and analysed against the background of its manifestation in South Africa. Secondly, the national health care system, with specific reference to the place and role of environmental health practitioners at national, provincial and municipal spheres – in relation to Cholera surveillance and control – was analysed. Thirdly, the relevant research that has been done globally has been analysed against the background of the findings of the above, together with work methods and procedures to be used by environmental-health practitioners during the surveillance and control of Cholera in the KwaZulu-Natal Province, South Africa. These include, inter alia: Work methods and procedures for Cholera case investigation; Work methods and procedures for sanitary investigations; and Work methods and procedures for identifying the sources of contamination in environmental waters. Finally, the conclusion and limitations was presented, and appropriate recommendations were made. These include: he need to educate all role - players, on the recent developments in the identification of Vibrio cholerae from environmental surface waters; Communication systems should be developed that allow the Director: Environmental Health to communicate urgent environmental health information directly to the Minister of Health; he training of environmental-health practitioners on detailed work methods and procedures for the surveillance and control of Cholera; and the existing national Cholera control guidelines need to be updated to include relevant environmental health situations when emergencies arise.
