Aspects of the biology of the sharptooth catfish, Clarias gariepinus (Burchell, 1822) were studied in a clear coastal lake (Lake Sibaya, KwaZulu.). Catfish reach maturity towards the end of the first year (total length 200-250mm) and breed in summer. Gonadal maturation is cyclical, and most fishes are ripe between September. and January e ach year. Maturation stages and fecundity are described. Twenty-two catfish spawning runs were witnessed. There were no large aggregations of catfish before the Summer rains, as reported in some impoundments and rivers, but catfish accumulated on the shallow terrace immediately before a spawning run. Spawning usually took place in flooded marginal areas after heavy rain on dark calm nights. Peak activity occurred between 20h00 and 02h30. Pre-nuptial aggression, courtship and mating are described and illustrated in detail for the first time from field observations. Gonadal products are released while in amplexus and fertilized externally. The eggs have an adhesive disc for attachment to plants, and develop rapidly. Early development and feeding are described. The growth rate of catfish was determined using rings on the pectoral spines, and validated using recent techniques. C.gariepinus in Lake Sibaya grow rapidly and remain in good condition to a length of 500mm, but larger catfish have a poor growth rate and condition, and few exceed 650mm. The modal length and weight of the Sibaya population is intermediate between that of other populations but the number and condition of larger catfish in Lake Sibaya is lower. Other studies on C.gariepinus growth are reviewed. Very high and low first year increments obtained previously may be due to methodological errors, but catfish do appear to have variable growth rates. The size reached by C.gariepinus is reviewed. Catfish are equipped morphologically and behaviourally to feed on a wide variety of·prey in different situations, but they usually feed at night on exposed, active benthic organisms. Social hunting facilitates the capture of prey which is too fast or manoevrable for a single predator. Food preferences are scored by three different methods and presented for the total catfish population and for different length groups, seasons, and habitats. Juveniles feed more often and on a greater variety of prey, and their condition is better than that of adults. The proportions of several food items in the diet changed at different lake levels as marginal areas became inundated. In particular, increasing lake levels resulted in a change in relative density of three cichlid prey in the shallow water feeding area of catfish. This situation provided the opportunity to study the effect of changing cichlid density on predation by catfish. The world literature on factors influencing the predator-prey relationship in fish is reviewed and several key factors are identified. The interaction of fish predators and prey in Africa, and particularly Lake Sibaya, is examined in detail, and prey density, modified by accessibility, is found to be an important factor. The effect of cichlid prey density on catfish predation was therefore investigated using field collections and experimental observations. Catfish prey on the cichlid species with greatest relative abundance, with some deviations which can be explained in terms of accessibility. The experimental results also describe feeding periodicity, imitative hunting and the effect of water depth , day-night light intensity changes and predator number on predation efficiency on cichlids. Catfish predation is discussed in terms of recent predation theory, and it is concluded that their ability to switch from one prey to another as prey availability (= density+ accessibility) changes , is an an important aspect of their success as predators. Catfish predate more efficiently on invertebrates, but feed largely on fishes after the first year. This preference for fish prey is probably related to food quality, as fishes contributed over 75% of the energy content of all ingested food, as well as abundant protein and the correct amino acid balance. Finally, I conclude that the role of C.gariepinus as a predator on S.mossambicus is three-fold: (a) to enhance species' fitness by removing enfeebled individuals i.e. to act as a 'cleanser' (b) to restrict the distribution of prey under certain conditions i.e. act as a 'restricter' (c) to dampen fluctuations in cichlid abundance i.e. act as a 'regulator'. The relative importance of these roles may alter at different lake levels in Lake Sibaya in response to changes in the vulnerability of fish prey.

Dissertation submitted in partial compliance with the requirements for the Master's Degree in Technology: Education (Management), Durban Institute of Technology, 2003. / The introduction of Curriculum 21 in South Africa in 1998 has brought with it added responsibilities for parents. According to the South African Schools' Act, No.84 (1996), parents have been granted powers to "support teachers in the performance of their task "and "determine subject choices" for their children. However, when Curriculum 21 was introduced in 1998, relevant programmes for introducing parents to these ideas dia not exist. According to Schlebusch and Spady (1999) family, home, identity and respect are important features of Curriculum 21 and only parents can create the best conditions for the academic development of their children. Therefore, the involvement of parents in the education of their children is vital. This dissertation is a case study of a rural KwaZulu- Natal public school, Hopewell Primary School, in which a pilot study of a programme to introduce parents to their responsibilities in the implementation of Curriculum 21, was first introduced. / M

Rehabilitation is a dynamic process influenced by factors related to more than one field of ecology. It is therefore necessary to consider all these components when assessing the rehabilitation, although in the initial stages the successful revegetation of the disturbed areas is the most important criterion. Richards Bay Minerals, on whose mining site this project was carried out, is dredge mining heavy minerals on the north coast of Natal, where they have rehabilitated mined areas since 1978. This project has been carried out to establish: 1) The success of their dune forest rehabilitation using quantitative techniques. 2) The available seed bank in their rehabilitation stands. 3) The similarities in the succession taking place in rehabilitation stands compared to the revegetated stands in the vicinity of Richards Bay. 4) The best methods for creating alternative vegetation communities, especially grasslands, with a high species diversity on the mined tailings. This study reviews only the success of rehabilitation of the natural vegetation but other studies focusing on the insect, reptile, mammal and bird populations are also being undertaken by other researchers. No particular method of determining the success of vegetation rehabilitation has been chosen by restoration ecologists. Therefore in this study a broad range of quantitative techniques were used to show whether successional changes are occurring in the vegetation and physical environment. The results obtained from sampling the rehabilitated vegetation have shown that both the species richness and diversity are increasing as the returned vegetation matures. Levels of soil properties such as Sodium, Phosphate, Calcium and percentage organic matter have also risen with increasing stand age. Community complexity is also increasing with stand age, and TWINSPAN and DECORANA plots have separated out the differently aged stands based on their differences. A "pilot" study was done on the seed bank present in the rehabilitation stands. This has shown the presence of large amounts of early successional, mostly herbaceous species. Seeds of later successional and woody species were scarce which may be a result of the sampling intensity used. However seeds of late successional ground cover species were found in the older stands. Comparisons between the natural revegetation of disturbed areas in the vicinity of Richards Bay and the rehabilitation stands revealed similarities in both species composition and complexity. Species richness and diversity values are comparatively similar for the younger revegetated and older rehabilitation stands, and lWlNSPAN and DECORANA analysis techniques clustered the samples recorded from these areas in close proximity on their relative plots. The oldest revegetated sites contain a number of species found in the rehabilitated vegetation but as Acacia karroo has thinned-out in these stands many of these other species are now mature individuals. Attempts at rehabilitating an area of grassland at Richards Bay Minerals has not produced satisfactory species diversity and experimental manipulations were used to try and increase the diversity of the existing Eragrostis curvula dominated community. Of the several treatments used for the manipulation, a combination of burning and further topsoiling was the most successful in reducing Eragrostis importance and in increasing the species richness. Grassland topsoil spread directly onto the bare tailings produced an extensive vegetation covering over a short period but species richness was not significantly greater than for the existing Eragrostis dominated grassland, and further treatments and management needs to continue if this technique is to be employed. Only a limited amount of alien infestation of the rehabilitated areas was evident from the sampling undertaken during this research. As the removal of alien plants is an ongoing process and the rehabilitation stands are continuously monitored to identify any new invaders, this is not expected to become a problem. From the results of work done overseas and the rehabilitation carried out in South Africa it appears that it is possible to return natural vegetation communities on mined areas. That this is a lengthy process is to be expected but by manipulating the vegetation and continuously monitoring the process it may be possible to speed up development. Areas in need of further research have been identified based on the findings of this project. This will help to reinforce the undertaking of management proposals that will enhance the vegetation recovery and the success of the rehabilitation programme.

Submitted in fulfilment of the requirements for the Master of Health Sciences in Nursing, Durban University of Technology, 2017. / Tuberculosis (TB) is South Africa’s greatest community health problem. Nurses have a critical role in supporting patients in the TB treatment process. An estimated 480 000 new cases of Multidrug-Resistant Tuberculosis (MDR-TB) and 190 000 people died in 2014. An estimated 43 million lives were saved between 2000 and 2014 with effective diagnosis and treatment of TB. Despite these measures TB remains one of the world’s biggest threats. In an attempt to improve the practice of nurses in the prevention of MDR-TB, the knowledge of nurses with regards to the prevention of MDR-TB is essential. Aim of the Study The aim of the study was to describe the practice of the nurses in the prevention of MDR-TB and to determine whether the practice was effective in the prevention of MDR-TB. Methodology Quantitative, descriptive survey was used to conduct the study. Purposive sampling method was employed to select six primary health care clinics at uThungulu District. The target population consisted of professional nurses and enrolled nurses working in these clinics. The sample size was 122. The questionnaire was used to collect data. Descriptive statistics was used to describe the data graphically. In order to test for significant trends in the data, inferential statistics were applied. Results The findings of the study revealed that nurses were implementing measures of preventing MDR-TB like tracing of patients who interrupted TB treatment although there were inconsistencies with implementation of other measures. There were gaps related to attendance of TB courses by TB staff. Nurses were working in an overcrowded environment where it was difficult to implement measures for preventing MDR-TB. There was an increase in the workload due to the high number of patients having TB. Conclusion In this study, the majority of nurses working in primary health care clinics scored well in infection control measures with regard to practicing cough hygiene, placing patients in a well-ventilated area, collection of sputum from patients suspected of having TB and giving of health education to patients with TB and relatives but there areas that need improvement. The findings indicate knowledge gap with regard to TB. There is a need for attendance of short courses in TB, increase of staff attending to TB patients so as to cope with the workload and efficient allocation of resources. / M

The main focus of this thesis is the child support grant, as part of a broader social security system, in post-apartheid South Africa. Since the end of apartheid of 1994, the new South African government has sought to redress the racial imbalances and inequalities of the past by engaging in measures of redistribution. Central to this pursuit of redistribution has been a restructured system of social grants, of which the child support grant is the most significant. However, the post-apartheid government has adopted a largely neo-liberal macro-economic strategy such that social inequality and endemic poverty remain pervasive particularly amongst the African population, which includes the recipients of the child support grants. In adopting a sustainable livelihoods framework as the main theoretical perspective, the thesis seeks to understand the livelihoods of child support grant mothers in the face of conditions of extreme poverty. It does this through a localised study of twenty child grant mothers in Sinathingi Township in KwaZulu-Natal Province. In examining the livelihoods of these child-grant mothers, the thesis brings to the fore that mothers and their children do not exist as autonomous living units but are embedded in a broader set of social relations, including intra-household relations and relations with the fathers of the grant-children. It also demonstrates that child-grant mothers are not simply victims of structures of poverty in contemporary South Africa, but actively construct their livelihoods through a range of activities and strategies which show perseverance and ingenuity.

Submitted in fulfillment of the requirements for the degree of Master of Health Sciences (Nursing), Durban University of Technology, Durban, South Africa, 2017. / BACKGROUND: Quiet often when students return from clinical placement, complain of being abused by patients and their relatives. Student nurses view clinical placement as an anxiety producing part of the nursing programme (Magnavita and Heponiemi 2011: 208). As a result, some resign and leave nursing fearing for their lives. AIM OF THE STUDY: To determine the extent and types of violence experienced by student nurses from patients and their relatives or friends in public hospitals in KwaZulu-Natal, and whether this leads to intentions to leave the nursing profession. METHODOLOGY: A quantitative, descriptive cross sectional survey approach conducted amongst student nurses (n=421) at KwaZulu-Natal College Nursing R425 Program starting from their first year of training up to the midwifery module. Self-Administered Questionnaires (SAQ) were used to collect data and data analysed using SPSS version 23. RESULTS: All respondents (n=421) completed the SAQ (annexure B). Many student nurses, especially female students, are victims of intimidation, bullying and verbal abuse as opposed to physical and sexual abuse by patients’ relatives and patients. The workplace violence against student nurses resulted in anger and absenteeism. The majority have not reported any abuse and they were not even aware of any policy that exists in their institutions against any form of violence. DISCUSSION: Findings in this study revealed that student nurses, like all other nurses, were also at a high risk of workplace violence. This may be because nurses have the closest contact with patients and their relatives; hence they are at high risk of exposure to violence. Since all settings are potentially high risk for violence, it is therefore necessary for the management to improve security in all high-risk areas for the student nurses to be safe. RECOMMENDATIONS: Public hospitals and the Department of Health (DOH) needs to formulate clear policies regarding violence against student nurses, and information on how to report the occurrence. There is a need for development or improvement of policies, procedures and intervention strategies. The DOH needs to address the issues of violence by implementing strategies to create a supportive environment that facilitates empowerment for the positive emotional wellbeing of student nurses. Managers have the responsibility to create and maintain zero tolerance regarding workplace violence. Public hospitals need to employ Managers with required skills and higher education to deal with workplace violence. There is a need for further research and more details on workplace violence and its cause. / M

Submitted in fulfillment of the requirement for the Degree of Master of Management Sciences Specialising in Business Administration, Durban University of Technology, Durban, South Africa, 2017. / In the electricity prepayment metering industry the continuous increase in customers’ expectations and technological innovation demand that leading firms in the industry differentiate themselves from the competition by going beyond customers’ present expectations. Thus, organizations which have set their goals on mere customer satisfaction are, from a customers’ perspective, deemed to be of limited value and may subsequently lack the anticipation and preparation essential to meet the demands of the future. Electricity prepayment metering market competition today is forcing organisations to seek the means to gain customer satisfaction, and thus aim to sustain their future in times of economic instability. The study revealed that the most effective way to retain customer satisfaction is consistent service quality that decreases the cost of attracting new customers and raises sales and market share. The quality of service is one of the most effective factors in creating competitive advantages and advance business. Factors that influence customer satisfaction in the electricity prepayment industry were investigated and tested. The study also attempted to identify the critical factors, as identified in the literature, among those investigated: service quality, customer expectations, customer perception and customer retention. Against this background, the study sought to determine the interrelationship between customer satisfaction and the critical factors of customer satisfaction with Conlog Electricity Prepayment Meters in KwaZulu-Natal. The research developed to ascertain subjects’ perceptions of the critical factors of customer satisfaction; determine the interrelationship among the critical factors of customer satisfaction; and explore the relationship between customer satisfaction and the critical factors of customer satisfaction. The research population comprising of Conlog electricity prepayment metering customers in KwaZulu-Natal was selected and interviewed. Questionnaires were distributed through electronic mail and self-administered for data collection and a sample of twelve respondents was selected for interview. Interviews were analysed using conversational analysis and the data collected from the interviews were merged with the questionnaire data, seeking depth as well as breadth. Data collected from respondents was analysed using descriptive and inferential statistical techniques. The tool utilised to analyze data was the Statistical Package for the Social Sciences (SPSS) version 22 (SPSS Inc., Chicago, Illinois, USA). A p value < 0.05 was considered as statistically significant. Conclusions and recommendations were drawn from the literature and the findings of the study. The results of the study revealed that service quality is the most significant critical factor of customer satisfaction. The study recommends that the management of Conlog can use the specific data obtained from the measurement of service quality in their strategies and plans. The study further recommends that Conlog allocates resources to this effect to provide better service to their customers. The results and findings of the study will provide further information concerning customer satisfaction and customer perception in the prepayment metering industry in KwaZulu-Natal. It will also contribute to future industry research, setting the ground for further research in measuring levels of customer satisfaction in the electricity prepayment industry in South Africa. / M

South Africa is not well-endowed with indigenous forests and those that remain are known to be degraded and declining at an alarming rate. This constitutes a direct threat to the quality of life of the resource-poor rural households which are directly dependent on the resources indigenous forests offer, as well as to ecological integrity. It is also recognised that the declining tree resources, particularly the indigenous tree species of high value, are increasingly threatened by a number of growing subsistence demands. This emphasises the need to establish, cultivate and conserve high-value tree species. Community forestry is recognised as a viable option for optimising land productivity; reducing pressure on indigenous forests and woodlands; ensuring a sustainable supply of desired tree products and services; and improving the quality of life of the resource-poor rural households. The primary purpose of Community Forestry Development (CFD) in the Hlabisa District is the provision of an information service and of technical support to enhance the livelihoods of rural communities by means of tree-related resources. Community forestry mainly focuses on tree resources that form an integral part of or contribute to rural people’s livelihoods. This includes small-scale growers (woodlots), woodlands and indigenous forests. Community forestry can be defined as tree growing and managed by the people for the people. Community forestry encompasses a wide range of activities which include farm forestry, agroforestry, village planting, woodlots, woodland management and indigenous-forest management by rural people, as well as tree planting in urban and peri-urban areas. Natural forests in South Africa account for less than 1 percent of the total land area. It has been suggested that these natural forests will no longer be able to meet the demand for forest products by 2020. The KwaZulu Department of Agriculture and Forestry embarked on community forestry in 1976 (but only on an ad hoc basis) as a possible solution to this dilemma. Later, the two South African pulp and paper giants, SAPPI and Mondi, started the Project Grow and Khulanathi Schemes respectively. One of the objectives of out-grower schemes was to encourage rural communities to plant trees on their own lands for the economic, social and environmental benefits trees offer. For example, timber could be sold to forestry companies. Financial assistance was offered to these communities to encourage implementation of such schemes. This exercise was aimed at bringing economic activity, capacity- building and community empowerment to the rural areas. The growers would benefit from the financial assistance and the readily available market provided by the company, while the company would be able to satisfy its demand for timber.

This study formed part of a larger provincial marine systematic conservation plan for KwaZulu-Natal (KZN), South Africa, called SeaPLAN. Owing to budget and time constraints, not all ± 1640 fish species that occur in the region were considered. A method to prioritise species was therefore developed to identify those species which were most at most risk of being excluded by a conservation plan based primarily on habitat representation (i.e. SeaPLAN). The method was based on three underlying principles: (i) species with limited conservation options; (ii) threatened species; and (iii) inherently vulnerable species. From these three principles, seven criteria were defined (e.g. endemic or rare species). Sixtyseven species met the qualifying conditions for these criteria and were consequently included in this study (FishPLAN). In order to map the distributions of these 67 fish species, the spatial and temporal accuracy of existing marine fish data for KZN was investigated. Only 17 percent of the data evaluated met the spatial resolution requirements of 1 km2, while temporal resolution was high: >99 percent of the data were collected at daily resolution. A resulting recommendation is that future data collection employ handheld data recording devices (with GPS capability), in order to increase the spatial accuracy of data, minimise human error and improve the efficiency of data flow. Species life cycle envelopes (SLICES) were developed to capture spatial differences in areas occupied during three life-cycle phases (reproductive, juvenile and feeding). Two distribution modelling techniques were used: Maxent, which uses quantitative data, and CHARMS (cartographic habitat association range models), which uses qualitative range data. A combination of statistical and biological criteria was used to determine the most informative and appropriate model for each species. Species distribution models (SDMs) were constructed for three temporal partitions of the data: annual, summer and winter. Patterns of species richness developed from the seasonal models showed seasonal differences in patterns that conformed to known seasonal distributions of fish assemblages: richness was higher in southern KZN during winter, while it was higher in northern KZN during summer. The resulting SDMs were used to develop a conservation plan for fish: conservation targets were set using the minimum recommended baseline of 20 percent of a species’ range, to which biological retention targets (additional proportion of the range) were added, in an attempt to ensure species persistence. The conservation targets were then adjusted using catch per unit effort (CPUE) data to match seasonal abundance of a given species. Within the existing network of marine protected areas (MPAs), none of the species’ targets are met by MPA sanctuary zones (zone As) alone, and all species require greater areas of protection. Three areas, namely offshore of the Tugela River mouth, the reefs offshore of Durban, and Aliwal Shoal, were consistently identified as being important in addition to existing MPAs for conservation of the fish species investigated. The greater efficiency of a seasonal MPA network to protect seasonally varying distributions of biodiversity, suggests that this may be a useful tool to consider in conservation management. The outcome of a conservation plan from this study (FishPLAN) was finally compared with the broader, more inclusive conservation plan, SeaPLAN. This comparison demonstrated how conservation plans based on a single group of species run the risk of identifying areas that are appropriate only for the relevant species, and might fail to conserve biodiversity as a whole.

Submitted in fulfilment of the requirements of the Master of Applied Science in Food and Nutrition, Durban University of Technology, Durban, South Africa, 2016. / Background: The occurrence of absenteeism observed at the Coastal KZN FET College is very large. However, absenteeism of this magnitude is not inconsistent with observations from other educational institutions and work places around the world. Generally, absenteeism is coupled to the absence of good health, the presence of one or more non-communicable disease and the paucity of physical exercise undertaken by the personnel. Absenteeism in the work place results in avoidable financial costs to the employer, the employee, and the country as a whole. The wealth of literature shows that health concerns concerning adults are diet related. Diabetes, heart disease, hypertension, obesity, cancer and other non-communicable diseases (NCD’s) are increasing at an alarming rate, daily. A double-burden plagues South Africa: on the one hand there is over-nutrition (an excessive consumption of nutrients); while on the other there is under-nutrition (an insufficient intake of nutrients by certain groups of individuals). Factors such as urbanisation, globalisation, physical inactivity and consumer financial buying power have a significant influence on these health concerns. Aim: The data gathered in this study will be used to develop nutrition wellness education material as a component of a wellness programme for staff members at the Swinton Campus of the KZN Coastal FET College in Mobeni. Methodology: A needs analysis was undertaken to determine whether nutrition wellness education material as a component of a wellness programme for the institution was appropriate. Three 24-hour recall questionnaires gathered from the staff, data on eating habits and nutrient intake were undertaken/collected. A food frequency questionnaire collected data on the frequency and variety of foods eaten. A health questionnaire gathered data on self-reported illnesses, consumption of alcohol, and smoking habits. The demographics of the group, living conditions, and amount of money earned and spent on food was assessed through a socio-demographic questionnaire. Anthropometric measurements assessed included blood pressure, waist circumference, BMI and Waist-to-height-ratio (WHtR). Results: The sample consisted of 138 participants of which 44% (n=61) were men and 56% (n=77) were women. Less than 50% of the respondents were food secure: only 65 persons (47.1%) in the sample always had money to purchase food. In this group 63.93% of the men and 71.43% of the woman were obese. Subsequently 86% of the women exceeded the waist cut-off point of 88cm while 16.39% of the men were above the 102cm cut-off point. Findings revealed that 42.62% of the men and 25.9% of the women had pre-hypertension while 8.20% of the men and 5.90% of the women were hypertensive. This study indicated that this group was nutrient deficient. The fruit and vegetable intake was between 134.44g - 175.69g per day for men and 124.00g - 183.30g per day for women. Energy, dietary fibre, vitamin A, vitamin D, calcium, magnesium and iodine were below the nutrient adequacy ratio. There were positive correlations between age and systolic blood pressure, waist circumference and systolic blood pressure, waist circumference and diastolic blood pressure and waist-to-height ratio and BMI. Conclusion: Central obesity and to a lesser extent hypertension as well as deficiencies in nutrients and minerals were present in this group. Although the participants indicated a good variety of food, the quality and quantities consumed were not adequate. A link between diet, physical activity and diseases of lifestyle has been demonstrated. A need for nutrition education as a component of the wellness programme is indicated. Nutrition education is important both within and outside the workplace. To make lifestyle changes it is essential that education and knowledge is made available. Behavioural habits including eating habits are principally learnt. If bad behaviour habits can be learnt, good behaviour habits can also be instilled. The proposed intervention is aimed at reducing the incidence of absenteeism and decreasing the presence of non-communicable diseases. It is important for staff members at a FET college to be present in the classroom so that education of quality can be conveyed to learners. Further, the good health of staff members facilitates the ability of teachers to perform their important task of educating young minds at all educational institutions. / M
