Lake St Lucia in northern KwaZulu-Natal, South Africa, experiences severe ecological stress during dry periods largely as a result of diminishing freshwater supplies and conditions of hypersalinity. Possible intervention involves diverting the Mfolozi River to the St Lucia Lake system. However, due to high sediment loading, water from the Mfolozi river requires considerable filtration before a link can be established. A suggested option considered in this study is to restore the existing sugarcane farmlands on the Mfolozi Floodplain (~20 800 ha) to previous wetland conditions to reinstate a sediment removal function amongst other benefits. Proposed restoration will have a direct impact on the industries currently supported by the iSimangaliso Wetland Park and the Mfolozi Floodplain (tourism, sugar, conservation). to understand a measure of such impacts, ecosystem services for both Lake St Lucia and the Mfolozi Floodplain were analysed (flood alleviation, water provision, water purification, sediment regulation, tourism, fisheries, vegetation for harvest, existence, cultural and research). Annual economic values for each ecosystem service were determined by means of valuation methods that included benefit transfer and replacement cost. Results showed a current annual minimum value of the Mfolozi Floodplain and Lake St Lucia as greater than R21 million and R1.1 billion respectively. Partial restoration of the floodplain (~6 000 ha) is expected to increase the sum of all ecosystem services values by approximately 26% for the Mfolozi Floodplain and by 23% for the St Lucia System. Full restoration (~20 800 ha) increases the total ecosystem services value by 88% and 50% for the Mfolozi Floodplain and St Lucia System respectively. Results showed that economic values for existence, fisheries, tourism and water provision increase by the greatest percentage for the St Lucia System under both restoration scenarios. Partial and full restoration of the floodplain will result in the greatest increases in economic value for the services existence, tourism, fisheries and the harvesting of vegetation on the Mfolozi Floodplain.

Rangers, as vanguards of wildlife conservation, are constantly fighting off armed poachers. That makes their work stressful and dangerous. In spite of this, their needs are neglected and are not considered as the focus is on saving wildlife. Undoubtedly, the African continent is not spared from the unrelenting poaching menace that threatens to drive the world’s wildlife spicies into extinction. In response to this scourge, countries, in their quest to safeguard these species from extermination, have signed various treaties, continuously come up with different strategies and pledged their support to fight illegal wildlife trading. This study was conducted at Hluhluwe-iMfolozi Park (HIP) and Mkhuze Game Reserve, which are under the management of Ezemvelo KwaZulu-Natal (KZN) Wildlife Management. These parks have turned into a battlefield between poachers and rangers. The intrinsic case study approach, which is explorative and interpretive in perspective, was used to unravel and describe the experiences from the world view of rangers. A descriptive qualitative research design was used to gain insight from the rangers about their challenges and needs in the workplace. Furthermore, developmental research was used to design and develop a tailor- made technology – a ranger resilience-building model – to assist rangers to deal with their workplace challenges. Focus group discussions were conducted with a group of rangers, while individual semi-structured interviews were conducted with managers in order to solicit information from purposively selected sample of rangers and managers at HIP and Mkhuze Game Reserve, that assisted in the development of the model. Ethical considerations, which involve the informed consent of the participants, confidentiality and privacy, participants’ right to withdraw from the study and the management of information, were applied to ensure that the participants were protected from harm. The collected data was analysed by using codes and themes that best described the experiences of the rangers, and data verification was done before the process of model development. It was evident that rangers are faced with a variety of workplace challenges, such as poor quality of work life, unpleasant living conditions, coupled with poor amenities, inadequte wellness interventions, and the poor management and implementation of policies by the Human Resources (HR) Department. Nevertheless, teamwork and their cultural practices were positive aspects that promoted their coping capacities in dealing with their everyday challenges. / Social Work / D.

Submitted in fulfillment of the requirement for D Phil: Management Sciences (Marketing), Durban University of Technology, Durban, South Africa, 2017. / There has been substantial research related to small and medium-sized Chinese enterprises in various countries. However, little research has been done on marketing by Chinese entrepreneurs in South Africa. Furthermore, no documented research has been conducted on the use of marketing intelligence by Chinese entrepreneurs in KwaZulu-Natal. For entrepreneurs, marketing intelligence plays an important role in the performance of their businesses. This study is aimed at assessing the application of marketing intelligence by Chinese entrepreneurs regarding their survival, growth and success in KwaZulu-Natal, South Africa. This study was conducted within the main industrial areas in KwaZulu-Natal, where Chinese entrepreneurs are based. The research was of a quantitative, descriptive and cross sectional nature, conducted among a sample of 120 business owners, managers, marketing executives and senior staff. The results revealed that the use of marketing intelligence in strategic decision-making by Chinese entrepreneurs in KwaZulu-Natal is very limited. The extent of awareness of marketing intelligence was fairly low. It also emerged that most of the respondents still acknowledged the importance of marketing intelligence and the role it could play in their businesses’ success. Pursuant to the general requirement for an original contribution in a doctoral thesis, the study provides a framework for current and potential Chinese entrepreneurs with regard to the application of marketing intelligence in their marketing planning. / D

Submitted in fulfilment of the requirements of the degree of Master of Technology: Nursing, Durban University of Technology, 2014. / South Africa has a high prevalence of obesity, and many people live with diseases where dietary adaptations are part of the management of the disease. Nurses are important in the facilitation of people obtaining dietary advice. While nutrition education is part of the nursing curriculum, student nurses’ knowledge of nutrition was not known, nor was their dietary intake and nutritional health status. The purpose of the study was to assess the nutrition knowledge of students at a nursing college, and to assess their dietary diversity. A quantitative study was used, with random sampling chosen for selection of campuses and convenience sampling for student group selection. Students of the KwaZulu-Natal College of Nursing were invited to complete a General Nutrition Knowledge Questionnaire. A Food Frequency Questionnaire was completed to assess dietary diversity, and respondents’ anthropometric measurements were recorded to assess Body Mass Index and Waist to Height Ratio. The results showed that a significant percentage of student nurses were overweight or obese. While students had a satisfactory knowledge of dietary recommendations and sources of different nutrients, their ability to make correct food choices, as well as their knowledge of diet-disease relationships was poor. They displayed good dietary diversity in their food intake. There were no statistically significant correlations between the students’ Body Mass Index and their knowledge, which assumes that the individual’s knowledge of nutrition does not directly influence their own food intake. It is recommended that aspects of the content in the nutrition curriculum be emphasised during the training of nurses in order to increase nutrition awareness in areas where knowledge was found to be lacking. / M

Background: In South Africa, limited research has focused on the task demands and workers responses associated with forestry silviculture work, particularly pitting and planting. The methods currently in use are manual, but despite our lack of understanding of the existing demands, advances in forestry engineering have resulted in an introduction of semi-mechanised versions of these tasks. This project aimed to compare the task demands of silviculture tasks using the current manual techniques and the more modern, semi-mechanised techniques. Methods: A holistic investigation focused on the worker characteristics of a sample of black male pitters and black female planters from the Kwa-Zulu Natal forestry industry, as well as biomechanical (spinal kinematics and L5/S1 forces), physiological (heart rate, oxygen consumption and energy expenditure) and psychophysical (ratings of perceived exertion and body discomfort) responses associated with manual and semi-mechanised pitting and planting. Results: The pitting task saw significant improvements in the spinal kinematic measures as a result of the increased mechanisation, with eight of the 16 recorded variables decreasing to a lower level of risk classification. Physiologically, the manual task was associated with a mean heart rate of 157 bt.min⁻¹ and absolute energy expenditure of 11.27 kcal.min⁻¹, which were not found to be significantly different to the values of 143 bt.min⁻¹ and 9.8 kcal.min⁻¹ recorded during the semi-mechanised technique. Psychophysical responses indicated that the workers perceived manual pitting to be more physically demanding than the semi-mechanised method. The manual and semi-mechanised planting tasks were, in general, found to be acceptable from a spinal kinematics perspective, with the majority of variables classified as low risk. However, the maximum sagittal angle was reduced by more than 20 degrees as a result of the new equipment. The physiological and psychophysical demands associated with manual planting were found to be within acceptable limits. Conclusion: In terms of pitting, it can tentatively be concluded that the semi-mechanised technique is better than the manual one, based on the biomechanical and psychophysical findings, however physiological demands require further investigation. When considering the planting techniques, the semi-mechanised method showed a slight improvement from the biomechanical perspective, but further physiological and psychophysical investigations are needed.

Videography is a valuable tool in biological and ecological studies. Using video footage obtained during previous coelacanth surveys, this thesis investigated coelacanths and their associated habitats in the submarine canyons of iSimangaliso Wetland Park, South Africa. This thesis aimed to (1) describe the biological habitats within the submarine canyons, (2) determine coelacanth distribution within these habitats, and (3) assess the use of computer-aided identification to successfully identify individual coelacanths. Seven different habitat types were noted with the most distinctive being the canyon margins that consisted of dense agglomerations of gorgonians, wire and whip corals, and sponges. Results suggested that although substratum type has a great influence on invertebrate community structure in the canyons, depth is the principal factor. Coelacanths were associated with cave habitats within the steep rocky canyon walls. Habitat analyses allowed predictive classification tree models to be constructed. Depth, underlying percentage of rock, and percentage cover of gorgonians and sponges were the most important variables for determining coelacanth presence and absence. The overall correct classification rate for the model was estimated at 96.6%, correctly predicting coelacanth absence (> 99%) better than presence (60%). Because coelacanths have a unique spot pattern it was possible to quickly and accurately identify specific individuals photographically using computer-aided identification software. Without any manual intervention by an operator the software accurately identified between 56 and 92% of the individuals. Identification success increased to 100% if the operator could also manually select from other potential matching photographs. It was also shown that fish exhibiting a yaw angle not exceeding 60° could be accurately identified in photographs. Each of the sections presented in this thesis represent a possible step towards analysing coelacanth-related habitats, locating and then analysing new habitats. Steps include first locating a population and then performing a habitat analysis. Coelacanth location within the different habitats can then be determined allowing the development of predictive models to potentially identify possible locations of new populations. The final step is to identify individual fish within the population for assessing demographic parameters and population monitoring.

Loggerhead and leatherback sea turtles nest on the beaches of the north-eastern portion of Kwazulu-Natal within the iSimangaliso Wetland Park. Loggerheads place ~60 percent of all nests within an 8 km stretch of beach, whereas leatherbacks tend to space their nests more evenly along the entire length of the monitoring area. The study aimed to determine nest site fidelity of loggerheads and leatherbacks (using four decades of nesting data housed by Ezemvelo KZN Wildlife) and the factors that influence nest site selection of both species within the 56 km of turtle monitoring area (32N to 100S) and the 5 km area of high-density loggerhead nesting (0N to 12N). The effectiveness of nest site selection was then determined through the hatching success of loggerheads over the 5km area (0N to 12N). Results showed that loggerheads show a high degree of nest site fidelity (~3 km) with nest site fidelity of individuals increasing over subsequent seasons of nesting, as well as these individuals using the same stretches of beach for nesting (the most popular area being 1N to 4N for repeat nesters). Leatherbacks displayed nest site fidelity of ~9 km and this did not increase over successive seasons of nesting. In terms of nest site selection, loggerheads and leatherbacks both avoided areas where low shore rock was present, whereas both species preferred nesting on beaches of intermediate morphodynamic state. Leatherback nesting was significantly higher in areas with wider surf zones. Both species were able to surpass the high water mark when nesting as nests below this point would be almost certainly doomed. Hatching success of loggerheads was comparative to high (83 %) relative to other studies, however, nest success varied across the beach from beacon 1N to 12N. Areas where highest nest success was observed were not areas of highest nest density presumably due to artificial lighting. Results from this study increase our understanding of the evolutionary biology of loggerhead and leatherback turtles in South Africa and the effectiveness of loggerhead nest site selection through hatching success.

This research was initiated as a result of the ever-evolving sophistication of criminal syndicates in their perseverance of organised crime and their use of electronic covert methodologies. Based on the researcher’s extensive managerial and operational experience, and on his unofficial observation of prosecutors, investigators and intelligence operatives, it became clear to him that there is a lack of evidence in court regarding serious and organised crime prosecutions. This can be attributed to the lack of use of investigative techniques, or investigative techniques being incorrectly used and/or a lack of knowledge regarding the use of investigative techniques. One such example of an investigative technique is surveillance or electronic surveillance. In this research study, the use and legality of electronic surveillance as a technique in the fight against organised crime, is discussed. Both national and international literature have been perused on the topic in question. Interviews were conducted with experienced former SAPS officers who were exposed to the use of electronic surveillance in the investigation of organised crime, as well as interviews with prosecutors, outlining the positive attributes of, as well as the shortcomings in, the use of electronic surveillance as an investigative tool in the investigation of organised crime. Surveillance or electronic surveillance has been in existence for a long period of time, but its usage or “know how” has been limited to only a few. The main purpose of the research is to highlight the importance of electronic surveillance as a covert technique in the investigation of organised crime. / Criminology and Security Science / M. Tech.

A Thesis submitted in fulfillment of the requirements for the degree of Doctor of Philosophy in Community Psychology in the Department of Psychology at the University of Zululand, 2007. / The major aim of the study was to determine whether broad-based initiatives, such as community based stigma reduction intervention programmes (later) based on the findings of the study, could have an impact on the uptake of HIV-testing and disclosure rate. The total sample comprised of 15 females and 15 males that were chosen from one of the support groups based at one of the selected Hospitals in KwaZulu-Natal Province. With the assistance of the hospital officials, the researcher was able to use the purposive sampling technique in selecting the respondents. From the themes, it became evident that people living with HIV and AIDS are faced with an important dilemma regarding whether or not they should reveal the HIV-positive status to significant others, in-depth interviews with the focus groups produced the following themes as accounts of emotional observations: isolation, social stigma, anger, revenge and depression. In the light of the findings of the study, a need arose for the establishment of an intervention programme aimed at addressing the common barriers associated with HIV disclosure. Community Psychology in particular, played a major role in shaping this study because of its action focus on groups. / National Research Fund (NRF)

A dissertation submitted in partial fulfilment of the Degree of Master of Library and Information Science (MLIS), in the Faculty of Arts at the University of Zululand, 2004. / The study defined customer care as an activity that allows customers to make direct contact with an organization to pass comments on products and their use. It also observed customer care as a customer service that seeks to acquire new customers, provide superior customer satisfaction, and build customer loyalty. The aim of the study was to investigate customer care strategies and services in academic libraries in tertiary institutions in KwaZulu-Natal. Two research assumptions were made. Firstly, it is assumed that academic libraries in South Africa do not have operational customer care strategies and services in place. Secondly, there is a relationship between poor information use and customer service and lack of customer care strategies and services in academic libraries in tertiary institutions. The study targeted 401 respondents, 307 students and 79 academic staff as well as 15 library staff. The study applied both quantitative and qualitative approaches and the population targeted was sampled by the use of stratified random sampling techniques. Three hundred and eighty six (386) questionnaires were distributed to both academics and students while interviews were conducted with the library management or unit and committee responsible for customer care. Statistical Package for Social Sciences (SPSS) was used to analyze data from academic staff and students. This software was selected because it is a user friendly data management and analysis package that can perform a variety of data analysis tests and presentation functions. Additionally, Microsoft Excel was used to analyze data collected from the library staff respondents. The study focused mainly on the problem areas, which depicts customer care policy and structures, customer care products and services, conducting of customer care, satisfaction of customers and strategies of customer care. It was discovered that some academic libraries do not have a formal policy on customer care in place. However, respondents were aware of and familiar with customer care policies in their libraries. Additionally, awareness and familiarity with information products and services was found to be known among library users. Furthermore, it was found that academic libraries do not have proper methods and strategies of customer care. Even those strategies that exist, are unknown among library users. It was further drawn out that library users are satisfied with information resources offered by their libraries. The study therefore, recommends that academic libraries should have a unit/person and committee responsible for customer care in place. In addition to that, library staff should attend workshops on customer care, to get formal training on how to deal with customers. It was observed that proper strategies and methods of conducting customer care must be implemented.
