M. Tech. Business Administration / The annual report issued by Jozini Municipality (2012) for the financial year 2010/2011 shows that the growth and development of small, micro and medium-sized business enterprises is adversely affected by the lack of entrepreneurial skills, lack of access to SETA-accredited skills based training opportunities, poor socioeconomic conditions, and poor infrastructural development. The purpose of the study was to identify and quantify factors that are known to affect entrepreneurial growth and skills development in the Jozini Municipality region of KwaZulu-Natal Province. The study shows the relationship between skills development, service delivery, entrepreneurship and socio economic empowerment in line with alleviation of poverty among the rural population in KwaZulu-Natal.

The increase of population and economic growth in South Africa has a negative effect on the water resources. Therefore, it should be well managed. The main concerns of the sustainability of water resources are hydropower, irrigation for agriculture, domestic and industries. Hence, the use of integrated water resources management in a single system which is built up by a river basin will help in water resources. This study was focused on water management issues: some of the principal causes of water shortages in UMdloti River are discussed. The current situation of water supply and demand at present is discussed. It also addressed some essential elements of reasonable, cooperative and sustainable water resources management solutions. Many developing countries are characterized as there is limited data availability, water scarcity and decrease of water levels in the dams. The eThekwini municipality is also having similar problems. Water resources have been modelled under this limited data using the hydrological modelling techniques by assessing the streamflow and observed data. The aim of the study was to address the issue of water management how water supply sources can be sustained to be manageable to meet the population growth demand considering the capacity of Hazelmere Dam demand downstream of the dam. Hydrological models, simulation, and decision making support systems were used to achieve all the research objectives. Hazelmere Dam has been modelled so that it can be used efficiently for the benefit of all users downstream of the dam for their economic and ecological benefits. Monthly reservoir inflow data for Hazelmere Dam was obtained from the Department of Water Affairs, South Africa. The nature of data is streamflow volume in mega liter (Ml) recorded for every month of the year. This was converted to mega cubic meter (Mm3) for use in the analysis herein. A period spanning 19 years of data (1994 – 2013) was used for the analysis. Six parametric probability distribution models were developed for estimating the monthly streamflow at Hazelmere Dam. These probability distribution functions include; Normal, Log-Normal (LN), Pearson III, Log-Pearson type III (LP3), Gumbel extreme value type1 (EVI) and Log-Gumbel (LG). It was observed that UMdloti River is smaller when compared with other rivers within the KwaZulu-Natal Province which could make it difficult to implement integrated water resources management. The hydro-meteorological data collected also has some limitations. The meteorological stations are far away to one another and this would make it difficult to attach their readings with the corresponding water basin. The comparison between the observed and simulated streamflow indicated that there was a good agreement between the observed and simulated discharge. Even though, the performance of the model was satisfactory, yet, it should not be generalized equally for all purposes. The erosion on the study area must be addressed by the stakeholders. It must be minimized in order to sustain the water resources of the UMdloti River. Erosion has a bad impact on the environment because it causes environmental degradation as well. Further investigations are recommended that account for the geological characteristics and the source of the base flow to make sure the rate of groundwater is sufficient for any future developments. Harnessing more energy from existing water sources within the frontier of the country is important in capacitating the South African Government’s commitment to reduction of the country’s greenhouse gas emissions and transition to a low-carbon economy while meeting a national target of 3,725 megawatts by 2030. This study also aimed to determine the amount of energy that can be generated from Hazelmere Dam on the uMdloti River, South Africa. Behavioral analyses of the Hazelmere reservoir were performed using plausible scenarios. Feasible alternative reservoir operation models were formulated and investigated to determine the best operating policy and power system configuration. This study determines the amounts of monthly and total annual energy that can be generated from Hazelmere reservoir based on turbines efficiencies of 75%, 85% and 90%. Optimization models were formulated to maximize hydropower generation within the constraints of existing abstractions, hydrological and system constraints. Differential evolution (DE) optimization method was adopted to resolve the optimization models. The methodology was applied for an operating season. The optimization models were formulated to maximize hydropower generation while keeping within the limits of existing irrigation demands. Differential evolution algorithm was employed to search feasible solution space for the best policy. Reservoir behavioural analysis was conducted to inspect the feasibility of generating hydropower from the Hazelmere reservoir under normal flow conditions. Optimization models were formulated to maximize hydropower generation from the dam. DE was employed to resolve the formulated models within the confines of the system constraints. It was found that 527.51 MWH of annual energy may be generated from the dam without system failure. Storage was maintained above critical levels while the reservoir supplied the full demands on the dam throughout the operating period indicating that the system yield is sufficient and there is no immediate need to augment the system. / M

Submitted in partial compliance with the requirements for a Master’s Degree in Technology: Homoeopathy, Durban University of Technology, Durban, South Africa, 2015. / South Africa has a dual healthcare system which consists of the public and private healthcare sectors. The private healthcare sector is used by a small percentage of South Africans as its services are more expensive. It makes provision for both allopathic and Complementary Alternative Medicine (CAM) practitioners. In contrast, the public healthcare sector employs only allopathic practitioners. Due to its services being rendered free of charge or at very low cost, it caters for the majority of the population and as a result has become overburdened. South Africa’s healthcare system is undergoing major changes in order to ease the burden on the public sector. The integration of homoeopathy into this sector is a possible viable solution. In order to facilitate integration, homoeopathic practitioners should be in agreement with this radical change and suggest ways in which this paradigm shift can be initiated. Hence, the overall aim of this study was to explore the perceptions of homoeopathic practitioners on their role in the public healthcare system in South Africa. The paucity of research on the perceptions of homoeopathic doctors suggests that this is an unexplored topic. This study therefore employed a qualitative approach based on the grounded theory method. Semi-structured interviews were conducted to determine homoeopathic practitioners’ perceptions of this phenomenon. Participants were selected using snowball sampling. Inclusion and exclusion criteria were also used to guide the selection of the research participants. The participants were interviewed individually using an interview guideline. Each interview was audio recorded and transcribed prior to data analysis. Once transcribed, the data was evaluated and analyzed manually. Four commons themes emerged from the data. The prevalence, frequency and variation (in the frequency) of each theme amongst the participants was established. Further analysis revealed links between all four themes. It was evident that knowledge/awareness of homoeopathy, the homoeopathic education system and the in-practice experiences of homoeopathic doctors all influence integration. These factors represented homoeopathic practitioners’ perceptions on such integration. The identification of the factors that influence integration is a clear indication that the homoeopathic practitioners who participated in this study are aware of their role in the public healthcare system and that the majority would welcome a shift from the private to the public healthcare sector. There is thus a need for further nationwide and more in-depth research on integration. / M

Submitted in fulfillment of the requirements of the Master of Health Sciences in Radiography, Department of Radiography, Durban University of Technology, Durban, South Africa. 2016. / Introduction The staffing crisis in the healthcare profession is an issue of global concern and South Africa is amongst the countries affected. Radiography is one of the professions in allied healthcare, that is affected. The statistics from the Department of Health (DoH) in KwaZulu-Natal (KZN), as at August 2013, indicate a marked decrease in the number of radiographers between 2008 and 2012. Private practice statistics were unavailable as these are confidential. Purpose of the study This study aimed to investigate the factors impacting on the retention of radiographers in KZN, in order to obtain information that may assist the DoH to improve their retention policies. The objectives of the study were to investigate: the reasons why KZN radiographers resign from their places of employment; the reasons why KZN radiographers choose to remain in their place of employment; and the factors that impact on job satisfaction. It was also the intention of this study to identify possible input that may contribute to the retention of KZN radiographers. Methodology This research was conducted in 11 districts of KZN, South Africa. Radiographers in all categories of radiography who had worked in KZN and then left the profession, those who had emigrated, as well as those who were working in KZN were targeted in an attempt to obtain a wide range of data related to the objectives. A quantitative, descriptive survey, using a cross-sectional design, was used. A stratified non-random sampling method was used to select the public and private hospitals from which data was collected. The target sample size was estimated at 300 radiographers from all four categories in both public and private hospitals, however the researcher obtained only 191 participants. The population size of KZN radiographers was 859; a sample size of 266 was required at the 95% confidence level. However, with the high attrition rate, the sample of 191 was more than adequate for the available number of respondents and was considered to be statistically acceptable by the statistician. The response rate was 191, of which 20 responses were received from the 29 emigrants contacted, and 16 responses from the 19 participants who had left the profession. Three questionnaires were used to target the three categories of the respondents. Results of the study The results of this research indicate that radiographers emigrated within ten years of graduating, which is a highly productive age. The workload was the main cause of resignation for four (66,7 percent) emigrants as well as five (31,3 percent) radiographers who had left the profession. Private hospitals were reported as having lower workloads, better facilities and greater financial rewards than public hospitals. Increased remuneration influenced the migration of radiographers from public to private practices. It was also noted that six (37,5 percent) participants reported the crime rate as being one of the three main factors contributing to emigration, while two (12,5 percent) highlighted poor financial reward in KZN. The third main factor was stated to be better prospects for professional advancement abroad. A lack of professional recognition and progression in radiography in KZN was identified by two (12,5 percent) participants as factors that impacted on job satisfaction. Conclusion and Recommendation This research study is of significance to the DoH and Department of Public Service and Administration (DPSA) as the results may be used to assist them in improving the level of retention of radiographers in KZN. The creation of opportunities for professional development, advancement and diversification of the scope of practice for radiographers, as well as role extension and expansion, were factors identified as being important in the retention of radiographers. The working conditions were found to be generally unsatisfactory and needing improvement. It is suggested that retention could be improved through the development of strategies such as introduction of flexible schedules, creation of opportunities for further training and education. It is further suggested that a similar type of study be conducted in other provinces so as to compare the retention challenges facing other provinces in South Africa and thereby gain a national overview. / M

Submitted in partial compliance with the requirements for the Master's Degree in Technology: Chiropractic at the Durban University of Technology, 2013. / Background: Paediatric visits to complementary and alternative medicine (CAM) practitioners results from a wide range of childhood disorders. As there are significant anatomical differences between children and adults, scientific evidence for the effectiveness of chiropractic care for adults is not applicable to paediatrics, leaving a paucity of information supporting the management of paediatric conditions by chiropractors. Most studies regarding paediatrics have been performed in first world countries, leaving a paucity of information about third world countries, where the health care milieu differs. Therefore, this research aimed to determine the practice characteristics regarding paediatric care in chiropractic practices in KwaZulu-Natal. Objectives: This prospective, quantitative, descriptive, cross-sectional study based on a focus group refined and piloted questionnaire, determined the practice characteristics with regards to paediatric practice amongst chiropractors in KwaZulu-Natal. The total sample population was n=118, with each practitioner receiving a Letter of Information and Informed Consent Form and a Questionnaire. Data was analysed using the data analysis tools of Microsoft Office Excel and a p value of <0.05 was considered as statistically significant. Results: A response rate of 36% was obtained. Most of the respondents were middle-aged, female chiropractors who had been practicing for less than a decade. Very few of the chiropractors held paediatric qualifications (18.6%). In terms of paediatric care, most of the respondents used a variety of conservative approaches as evidenced by the type and number of assessments, treatment and management procedures used in practice. Conclusions: The results showed that few chiropractors in KwaZulu-Natal see paediatric patients in their practices; however the chiropractors that managed paediatric conditions were predominantly conservative. This is positive for the chiropractic profession, as it shows diligent and responsible decision making within a vulnerable population group. Future research must assist with facilitating inter-professional relations with other health care professionals and public relations need to be aimed at creating more awareness generally regarding chiropractic paediatric care. / M

A thesis submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Doctor of Philosophy. Johannesburg, 2016. / This study is within the context of the Howiesons Poort Industry of the Middle Stone Age. This is a dynamic period of increasing behavioural and material complexity. In the lithic assembles, this can be seen in a strong bias towards the selection of high-quality fine-grained rocks. This has often been interpreted as evidence for long distance travel, reciprocal exchange, or even increased mobility. This study aims to determine what influence the mechanical properties of rock types exerted on the Middle Stone Age assemblages at Sibudu. This requires a consideration of the distribution of rock types across the landscape surrounding Sibudu Cave. The study was limited to hornfels and dolerite as these rock types dominate the Sibudu assemblage, and quartz and quartzite that were sometimes used at the site are exceedingly difficult to collect in large enough sample sizes to conduct experiments. It was important to carry out tests on the mechanical properties of hornfels and dolerite and to characterise them. Hardness, roughness, elasticity and brittleness dictate the ease of knapping as well as the durability of flaked tools and these rock properties can be measured by the mechanical tests described here. To understand how these properties affect the assemblage in practice, dolerite and hornfels flakes were produced and used experimentally for cutting and scraping leather. The edge damage produced was compared. Finally, preliminary analysis was undertaken of square C4, layer PGS, which forms part of the oldest Howiesons Poort layer at Sibudu. The information and insights gained from the mechanical tests and experimental work were used to interpret the role of mechanical properties for the archaeological sample of PGS. The results show that all rocks used at Sibudu are local, and do not support any models of long distance travel/trade, reciprocal exchange, or models of increased mobility. Dolerite and hornfels form the bulk of the assemblage at all times (except briefly in the post-Howiesons Poort), and there is a bias towards the selection of fine-grained rocks during the Howiesons Poort. Dolerite can be characterised as hard, tough, elastic, and rough, while hornfels is hard, brittle, and fine-grained. These properties affect knapping and the qualities of a tool’s edge. The properties of hornfels allow for knapping accuracy and predictability, and it is better suited to blade production and cutting. However, tool edges are not robust. Dolerite is not as easy to knap, but produces tools with a robust edge that are particularly suited to scraping. Each rock type appears to have fulfilled a different function at Sibudu. Most rock studies geochemically source rocks, establish models of rock procurement or show trends in rock selection for artefact classes. Mechanical studies of rocks have typically formed part of heat treatment debates (Brown et al 2009; Domanski & Webb 1992, 1994; Webb & Domanski 2008). Through the combined approach of mechanical testing, experimental knapping and tool use, and lithic analysis, this research provides a context for possible rock procurement choices at a time in the past when many African sites reveal a changing pattern of rock selection. / LG2017

A thesis submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Doctor of Philosophy The support of the Global Change and Sustainability Research Institute (GCSRI) towards this research is hereby acknowledged. Opinions expressed and conclusions arrived at, are those of the author and are not necessarily to be attributed to the GCSRI. February 2017 in Johannesburg, South Africa / Global change, specifically land cover change and climate change, are recognised as the leading drivers of biodiversity loss worldwide. Habitat loss has resulted in a loss of biodiversity and led to significant declines in species populations. Climate change is altering species distributions, ecosystem composition and phenology. Conservation planning is required to offset these dynamic threats to species persistence into the future. Plants form the basis of trophic structure and functioning and may not be able to track changing environmental conditions as well as mobile species. They thus represent an essential starting point for understanding climate change and habitat loss impacts. The patterns and processes which generate and maintain floristic diversity must be explored before global change impacts on these communities can be assessed and planned for at a landscape scale. This thesis investigates the environmental variables structuring indigenous plant community composition, pattern and turnover in grassland and savanna systems in KwaZulu-Natal. The threats posed by land cover change and climate change are explored and a coarse-grained landscape connectivity map developed to impart maximum resilience in order to maintain floristic diversity in the era of anthropogenically induced global change. The environmental variables correlated to floristic pattern and turnover were temperature, soil fertility and precipitation variables. The orientation of the temperature gradient conflicts with the soil fertility gradient, hence species with particular soil requirements will be hampered in their efforts to track the temperature gradient. The gradients were non-linear with turnover highest on dystrophic soils in warm and drier summer regions. The major drivers of land cover change were cropped agriculture, timber plantations (agroforestry), rural and urban development, dams and mines. The drivers of change differed according to land tenure type. The average rate of habitat loss in the province over an 18 year period was 1.2% per annum, levels which are considered unsustainable. A target level of 50% of natural habitat remaining is recommended. Environmental domains were identified using the environmental correlates of plant community composition. These were used to investigate climate change impacts using a collection of downscaled climate models. Conditions suiting savanna species are set to increase at the expense of conditions suiting grassland species raising significant challenges for the conservation of grasslands. Indices of habitat intactness and climatic stability were used to develop a vulnerability framework to guide conservation actions to mitigate global change impacts on floristic diversity. Building on the insights gained from the study, a connectivity map linking protected areas was developed, that if implemented, will maximise the opportunity to maintain floristic diversity into the future. The spatial location of the corridors was prioritised based on broad scale climatic refugia, high turnover areas and important plant areas for endemic and threatened species. The corridors were aligned along the major climatic gradients driving floristic pattern. The corridors represent the most natural and cost-effective way for species to adapt to climate change and persist in the landscape. This thesis provides new insights into two global threats facing plant communities in KwaZulu-Natal and provides a suite of products that inform dynamic conservation planning and directs appropriate conservation action. The results may be used to inform policy and legislation. / MT2017

Submitted in fulfilment of the requirements for D.Tech: Nursing in the Faculty of Health Sciences, Durban University of Technology, 2009. / BACKGROUND In South Africa, Integration of Services Policy was enacted in 1996 with the aim of increasing health service utilization by increasing the accessibility of all services at Primary Health Care (PHC) level. However, the problem with the policy arises in the implementation of integrated PHC (IPHC) as there is no agreed upon understanding of what this phenomenon means in the South African context. Hence, there is a need for shared views on this phenomenon. METHODS A cross-sectional study, using a qualitative approach was employed in this study in order to analyze IPHC in KwaZulu-Natal (KZN). A grounded theory approach was selected as it is a method known for its ability to make the greatest contribution in areas where little research has been done and when new viewpoints are needed to describe the familiar phenomenon that is not clearly understood. Policy makers and co-ordinators of PHC at national, provincial and district levels as well as PHC nurses at functional level participated in the study. The data was collected by means of observations and interviews. The sample size for interviews was comprised of 38 participants. RESULTS It emerged that there were three core categories that were used by the participants as discriminatory dimensions of IPHC in South Africa. These core categories were (a) comprehensive health care, (b) supermarket approach and (c) one stop shop. Based on the findings of the study, it was concluded that the phenomenon, IPHC meant different things in different contexts.
