- Description: The focus of this study is on the role the marriage counsellor should play in the Black community. This role is being placed in sharp perspective as a result of social change affecting the Black family. Problem-solving, including marriage counselling has traditionally been done by the extended family. This role of the family as a natural support system has been weakened by factors such as urbanization and Westernisation. This has prompted Black couples experiencing in particular marriage problems to make use of professional marriage counselling services from specialised and other welfare agencies. A major problem in the rendering of professional counselling services is that they are to a great extent based on Western civilization as far as basic philosophy and underlying assumptions are concerned. Thus intervention modalities used for marital problems in the Black community do not address the real needs of the people. The main objective of this study was to investigate how marriage counselling services are perceived in the Black community. It is expected that research findings would assist the helping professions make the necessary adjustments to make marriage counselling approaches more relevant to problems experienced in married life in the Black community. The study revealed that the family in the Black community is still regarded as the main problem-solver although people do go beyond the family for assistance. The nuclear family has also started to emerge in the Black community and bonds to the bigger family systems are beginning to loosen. The research findings indicated clearly that there is a need for professional marriage counselling and that services of this nature should be extended further into the Black community. A problem in this regard however is that the community will have to be educated to use these services

- Description: The demand for innovative end users of information technology is increasing along with the proliferation of computer equipment within the workplace. This has resulted in increasing demands being made upon educational institutions responsible for the education of computer end users. The demands placed upon the teachers are particularly high. Large class groups and limited physical resources make the task especially difficult. One of the most time consuming, yet important, tasks is that of student evaluation. To effectively assess the practical work of information technology students requires intensive study of the storage media upon which the students'efforts have been saved. The purpose of this study was to assess the suitability of criterion-referenced testing techniques applied to the evaluation of end user computing students. Objective questions were administered to the students using Question Mark, a computer-managed test delivery system which enabled quick and efficient management of scoring and data manipulation for empirical analysis. The study was limited to the classroom situation and the assessment of primary spreadsheet skills. In order to operate within these boundaries, empirical techniques were used which enabled the timeous analysis of the students' test results. The findings of this study proved to be encouraging. Computer-mediated criterion-referenced testing techniques were found to be sufficiently reliable for classroom practice when used to assess primary spreadsheet skills. The validation of the assessment technique proved to be problematic because of the constraints imposed by normal classroom practice as well as the lack of an established methodology for evaluating spreadsheet skills. However, sufficient evidence was obtained to warrant further research aimed at assessing the use of computer-mediated criterion-referenced tests to evaluate information technology end user learning in situations beyond the boundaries of the classroom, such as a national certification examination.

- Description: First tier automotive suppliers in the Nelson Mandela Metropole are under continued pressures created by the process of globalisation. To stay globally competitive suppliers, have to rethink their supply chain strategies. It is important that suppliers understand the environment that it operates within, this environment present first tier automotive suppliers with numerous problems and challenges. An analysis of this problems and challenges are needed and supply chain strategies need to be developed to overcome these problems and challenges. Before these strategies can be developed a full understanding of the supply chain is necessary. This dissertation aims to assess the problems and challenges facing first tier automotive suppliers, give a full understanding of the supply chain and present strategies to overcome these problems and challenges. The supply chain has become less structured and closer partnerships are needed between trading partners. The connectivity, transparency and visibility of the supply chain have improved through developments in the communication technology field. Strategies need to utilise these technologies to create a competitive edge. Effective supply chain strategies need to enable first tier automotive suppliers to deliver materials: At the right time; In the right quantities; At the right quality.

- Description: This portfolio of work represents three research projects on issues related to teacher education. The research was undertaken at Dr. W.B. Rubusana College of Education over a period of three years. The first project is a situational analysis that attempts to determine whether the college is capable of meeting the challenges placed on it by the evolving South African Educational System. The key finding is that the college is not ready to embark on the changes required by the Ministry of Education chiefly because its educators and learners are seemingly not ready to embrace change. The second project is a case study that attempts to determine whether a group of 12 Senior Primary students at the college are able to interpret photographs of the local environment and as such provide evidence of their ability to be environmental educators through the medium of geography. The findings indicate that they are only able to read the photographs at a very superficial level. Their poor communication skills and their disadvantaged backgrounds seem to prevent them from achieving the level of thinking required for them to be effective environmental educators. The third project describes, analyses and evaluates a fieldwork study done with a class of Senior Primary students at the college. While the students did not achieve the necessary progression from 'look and see' to 'enquiry based' fieldwork the project was valuable in that it was an educative experience for both teacher and learner and provides evidence of the value of action research and reflective teaching.

- Description: This research was initiated due to declining customer satisfaction indices in the Southern region of Eskom, an electricity utility in South Africa. Given the link between customer satisfaction and purchase intentions, the sustainability of the business is at stake. The validity of the current MaxiCare survey tool is questioned and explored, as is the congruence of management and customers' perceptions regarding the key service quality constructs in the industry. The study's objective was to provide management with a reliable and valid customer satisfaction survey instrument as an alternate to the existing tool and to use the knowledge gained through the research process to recommend improvement strategies aimed at closing specific satisfaction gaps identified. The research was performed in two stages; firstly, semistructured interviews with customers and management to gain an understanding of the most important satisfaction dimensions. These influenced the design of a survey instrument based largely on the SERVPERF tool with the inclusion of importance ratings per item in the second stage. The quantitative survey results were used to assess the reliability and validity of the research and to suggest areas for future work. The results show that communication, quality of supply, assurance and price are uppermost in the consumer's mind. Tangibles are not significant and the inclusion of empathy is inconclusive. Management and customer perceptions at a macro level are closely aligned, however the two populations are not in agreement as to the underlying micro considerations. Similarly, the MaxiCare instrument is found to be valid as a macro indicator but lacks sufficient detail to be useful as a strategic tool and needs to be supplemented with additional sources of market information. The survey instrument used in the second phase is both descriptive and reliable but the number of factors it measures, the mix of items and the inclusion of the 'importance' dimension need further refinement to improve its validity. Future revisions of the tool will provide management with specific information that allows them to focus improvement strategies on disgruntled customers and their key service issues.

- Description: The study focused on the development of an environmental education (EE) strategy framework in the Endangered Wildlife Trust (EWT) of South Africa. Evidence shows that the roles of conservation and biodiversity education could potentially be merged towards producing a practical strategy, beneficial to the organisation and its individual staff members. Questionnaires, interviews and the individual perceptions of staff members, as well as the analysis of relevant documents, suggested that the potential for the practice of EE towards the development of an EE strategy within the organisation is substantial. EWT staff members can contribute towards a change in the way that South Africans think about conservation and nature. Environmental ethics need to be promoted and understood by all. Within the EWT, environmental education activities are in place and diverse, yet they lack any form of monitoring and evaluation. The Trust is already practicing a form of EE but the potential to do more and the opportunities for expansion are unlimited.

- Description: The private and social returns to education literature share the same conclusion: that education is beneficial for both the individual and society. However, the theoretical underpinnings are flawed as the literature does not account for the main feature that leads to the acquisition of education: the private demand for education. An understanding of the factors that motivate the individual to invest in education would lead to a deeper insight as to why both private and social returns to education exist, and would provide a clearer framework on which to base the government funding of education. This thesis provides a first attempt at filling this gap by introducing a method of estimating the returns to government investment in education, which is labelled the ‘labour market drop-out rate approach’. The approach focuses on the social return to education, not in terms of graduate earnings, but in terms of the interaction of the graduate with the economy. The approach introduces a measure of expertise utilisation, based on the premise that there is no social return to an individual acquiring education if he or she does not utilise the acquired knowledge base on entering the labour market. The approach is tested using the labour market for marine scientists in South Africa as a case study. In this case the private demand for education is found to be heavily influenced by the provision of student bursaries from the National Research Foundation, with a resulting estimate of the social return to a degree in marine science being a mere 20% to 25%. Owing to this, a new approach to government investment in marine science is introduced, that of graduate contribution schemes. Of broader significance is the ease of application of this approach, it may be adopted to analyse any funding programme in which a government may decide to invest. As such, the labour market drop-out rate provides an extension to the returns to education literature through its theoretical dealings of the private demand for education, as well as a practical tool which government agencies can use to evaluate the efficacy of any government funding of education.

- Description: The aim of this oral history study is to explore the ways in which constructions of gender have brought women to the point where they now bear most of the burden of responsibility in their relationships with men and for the wellbeing of children. This study speaks into the gap of the undocumented history of women's lived experience as told by women themselves. It is a generational study which charts the transformations and coping strategies of women in Xhosa households since the 1940s. The study found that the familial burdens related to women's sexuality and fertility, raising of children and financial responsibilities in a time of HIV / AIDS have increased. Teenage pregnancies, the discipline of children, HIV / AIDS and the ever present aspects of poverty are major issues these women face. The stress of day to day demands on their lives precluded them the opportunity to reflect on the underlying causes and historical roots of their circumstances. Little understanding of the gendered order of their lives was expressed by the respondents. The use of feminist methodology authenticated the women's stories as they produced knowledge of their lived experience. The interview questions raised awareness of the gender bias underlying much of their struggles at home. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: The study takes place in the context of the Southern African Development Community’s Regional Environmental Education Programme (SADC REEP). The SADC REEP is a programme of the Food Agriculture and Natural Resources Directorate of the SADC Secretariat. The programme is implemented through four components namely policy, networking, training and learning support materials development. The bulk of the policy budget is in the form of seed funding to support policy initiatives in the member states. The intention of this study is to illuminate factors that influence the deployment and use of seed funding to support environmental education policy processes within the SADC REEP. To sharpen the understanding of the context within which these activities take place, the study looks at the global and regional landscape of policy events and their influence on policy in the sub-region. The study also looks at the landscape of the fields within which environmental education is embedded, the power relations, and the notion of agency in environmental education policy processes. The discourse in environmental education policy processes is analyzed by drawing on Bourdieu’s constructivist structuralism to highlight some of the social and institutional complexities in dynamic fields, capital and policy context. The research takes a qualitative interpretative approach using case study methodology to explore the processes and influences that have a bearing on the SADC REEP policy sub-component, specifically the deployment and use of seed funding for policy initiatives. The findings show the complexity of the variables at play in shaping the processes of developing and reviewing environmental education policies in the sub-region. These variables include discourse that is used, economics and politics of the responsible institutions and actors, as well as relationships between the environmental field and education field. The results point towards a need to clearly understand the policy context within which the SADC REEP is operating in order to make correct assumptions, to develop realist expectations, and to put in place appropriate mechanisms that will effect the expectations. The study recommends further probing of the relationship between the actors and networks in relation to the success of policy processes. It also recommends a further exploration of the SADC REEP’s open-ended approach with respect to articulating the monitoring and consolidation of the successes in supporting environmental education policy processes.

- Description: Commonage is land that is usually found adjacent to a town, which is owned by the local municipality and acquired through state grants or, historically, through the church. Since the new government dispensation in 1994, poor and previously disadvantaged residents have acquired access rights to commonage for agricultural purposes. Through the Department of Land Affair’s Commonage Programme, local municipalities are acquiring more commonage land for purposes of agriculture and grazing livestock. Commonages are increasingly being recognised as an important livelihood asset for the poor and unemployed residents’ of towns and rapid urbanisation is contributing to the increasing use of commonage for livelihood provisioning. Some municipalities view commonage as a key asset to promote Local Economic Development, while others are finding it difficult to manage the land effectively, to the extent that some analysts see tragic ecological consequences occurring due to over-grazing. This has been likened to the “tragedy of the commons” as advocated by Hardin in 1968. Commonage and common property resource systems have many similarities and co-management has been advocated as a potential management regime for commonage. Researching the policy framework, institutional structures and management bodies involved in commonage, gave a better understanding of the governance and management of the commonages in Grahamstown, Fort Beaufort and Bathurst. Current management attempts are not ensuring the efficient, equitable and sustainable use of these commonages. The governance framework is not adequately supporting proper management. In an environment of resource-poor institutional bodies, adaptive co-management could prove to be the most effective system to ensure the sustainable use and development of this natural resource. Furthermore, commonage is no longer contributing to the Land Reform Programme. Commonage should be better integrated into agrarian reform through lease schemes and an efficient Emerging Farmer Programme.

- Description: The study reported here utilised a theory of levels of geometric thinking. This theory was proposed and developed by two Dutch mathematics educators, Pierre van Hiele and his wife, Dina van Hiele-Geldof. The van Hiele theory enables investigations into why many students experience difficulties in learning geometry. In many nations, such as the UK, the USA, Netherlands, the USSR and to a certain extent, Nigeria and South Africa, research evidence has indicated that the overall students’ mathematical competencies are linked to their geometric thinking levels. This study is the first of its kind to apply the van Hiele theory of geometric thinking in the Namibian context to analyse geometrical conceptualisation in Grade 12 mathematics students. In all, 50 Grade 12 students (20 from School A and 30 from School B) were involved in this study. These students wrote a van Hiele Geometry Test adapted from the Cognitive Development and Achievement in Secondary School Geometry test items. Thereafter, a clinical interview with the aid of manipulatives was conducted. The results from this study indicated that many of the School A and School B students who participated in the research have a weak conceptual understanding of geometric concepts: 35% of the School A and 40% of the School B subsamples were at the prerecognition level. 25% and 30% of the School A, and 20% and 23.3% of the School B students were at van Hiele levels 1 and 2 respectively. An equal number of students but different in percentages, 2 (10%) in School A and 2 (6.7%) in School B, were at van Hiele level 3. Only one student from School B attained van Hiele level 4. These results were found to be consistent with those of previous similar studies in UK, USA, Nigeria and South Africa. The findings of this study also highlight issues of how the Namibian Grade 12 geometry syllabus should be aligned with the van Hiele levels of geometric thinking as well as the use of appropriate and correct language in geometrical thinking and problem solving.

- Description: Most central banks use short-term interest rates as their main instrument of monetary policy. It is assumed that a change in policy rate will influence interest rates set by commercial banks, but this is not usually the case. Commercial banks adjust their interest rates in response to changes in policy rate with lags, which make their interest rates sticky. Stickiness in commercial banks interest rates have been seen as an obstacle to the smooth transmission of monetary policy decisions. Despite the importance of the transmission process, little attention has been given to a systematic measurement of the degree of response of commercial banks‟ interest rates to changes in monetary policy stance in the Anglophone West African countries, specifically within the West African Monetary Zone (WAMZ) economies. Against this backdrop, this study explores the interest rate adjustment dynamics using monthly interest rate series on discount rate, treasury bill rate, commercial banks‟ deposit and lending rates from 1989 to 2009 (for Gambia, Nigeria and Sierra Leone) and from 2000 to 2009 (for Ghana). Specifically, the study set out to examine how lending and deposit rates respond to changes in the official rates and to see whether there is a convergence among the rates over time. Also, to examine the relative adjustment of commercial bank lending rates to changes in the official rate when there is disequilibrium. The analyses were twofold: a full sample period and a rolling window analysis. Following Cottarelli and Kourelis (1994), the study employed cointegration technique and an asymmetric error correction model to obtain the short-run and long-run parameters from which the error correction coefficients, mean adjustment lags and asymmetric mean adjustment lags were estimated. The results for the entire sample period revealed that the long-run pass-through in Nigeria was 81% and 67% for lending rates and deposit rates respectively. In Ghana, it was 66% and 69% for lending and deposit rates respectively. While in Sierra Leone, long-run pass-through was 62% and 72% for lending and deposit rates respectively. In Gambia, it was 50% and 40% for lending and deposit rates respectively. On the other hand, the short-run pass-through was found to be lower compared to the long-run pass-through: in Nigeria it was 66% and 47%; in Gambia, 26% and 29%; in Sierra Leone, 30% and 13%; and in Ghana, -6% and 35% for lending and deposit rates respectively in each country. The pass-through estimates for the rolling windows were mixed for short-run and long-run pass-through. The mean adjustment lags suggest that the speed of adjustment of Lending rates for full sample period were two, two, seven and twelve months in Nigeria, Ghana, Sierra Leone and Gambia respectively. While for deposit rates they were five, six, seven and eighteen for Ghana, Nigeria, Gambia and Sierra Leone respectively. The average speeds of adjustment for the rolling windows were four and five months for lending and deposit rates respectively. Weak evidence of convergence was found in lending and deposit rates in the short-run and long-run pass-through among the countries. However, the results suggest that the magnitude and speed of the pass-through amongst the countries on average were high compared to emerging Asian countries. Significant asymmetric adjustments were found in the lending rates for Gambia and Sierra Leone, while in Gambia and Nigeria there were asymmetries in deposit rates. Based on the evidence provided, interest rate pass-through is high in Nigeria and Ghana compared to Gambia and Sierra Leone and this calls for the harmonization of financial policies on the part of the financial authorities in the WAMZ. Viewed solely from an interest rate pass-through, the lack of convergence among the countries suggests that WAMZ is far from ready for a monetary union. The relatively low pass-through in some of the countries suggests rigidity in the banking system which may be due to underdevelopment of the system. Thus efforts geared toward strengthening the banking system and the financial system as whole would further enhance the prospect of a monetary union among them.

- Description: The Earth's health is deteriorating and will deteriorate even more rapidly unless people adopt eco-friendly policies. Green building has long been a concept but it has not yet been universally applied in practice. The concept of sustainability emerged in the 1970s and can be associated with the energy crisis and environmental pollution concerns. This research is aimed at investigating whether building “green” is more demanding than non-green buildings in terms of cost and the use of green materials against traditional materials; whether professionals in the construction industry are knowledgeable in terms of green buildings; and lastly, to determine whether green buildings are contributing significantly to the environment. The literature reviewed and results of quantitative research amongst professionals from the Island of Mauritius formed the basis of the study. The study revealed that green building is expensive relative to traditional buildings considering. However, the concepts employed (for example: lower energy use, less waste disposal, lower water usage, and sustainable design) provide green buildings with long term savings. Furthermore, the scarcity of natural materials makes it expensive. The study also showed that contractors and professionals have a preference for traditional materials over green materials thus making them more familiar with traditional materials. Contractors and professionals are believed to understand green materials only on a limited basis. This may be attributed to the specific environmental issues involved; however, the research revealed that the professionals are familiar with the basic concepts of green buildings. Lastly, the research showed that green building is still at its infancy but the benefits of green buildings are understood; resulting in green buildings having a good growth potential. The study should be valuable to construction industry professional and clients.

- Description: Fundamental changes in the global economy are changing the basis of organisational competitive advantage. The challenge in attaining a competitive advantage is characterised by factors such as increased competition, market volatility, geographically dispersed operations, customer awareness, raising workforce diversity and stringent regulatory regimes. These factors have driven, and in turn have been driven by, an increasing complexity of products, services and the processes that create value, resulting in changes in the structural and functional dimensions of the organisation. Business executives and academics recognise the shift in value creating assets from the traditional land, labour and capital to intangible assets such as knowledge and information becoming the most important resources an organisation can muster.The combination and integration of intangible assets such as human resources, structural and relational resources has been grouped under the umbrella of intellectual capital. This study comprises of a single descriptive case study analysis to ascertain how intellectual capital is managed strategically to gain a competitive advantage in an organisation in the banking and financial services sector in Zambia. Based on document review and semi-structured interviews, this thesis investigated the extent to which an organisation in the banking and financial services sector in Zambia leveraged intellectual capital to gain competitive advantage. In this study it was found that there is a low level appreciation of the intellectual capital phenomenon as a strategic management tool in the participating organisation. However, the organisation has adopted aspects of intellectual capital and has implemented them successfully accounting for the organisation‘s competitive edge in the market.

- Description: The aim of this study was to investigate spatial changes in the trophic and energy pathways of the benthic community in the shallow shelf waters of the sub-Antarctic Prince Edward Islands (PEI). A combination of stable isotope and fatty acid analyses were used to provide a time-integrated view of the assimilated feeding history of selected components of the PEI benthic community. This study forms part of the larger project entitled “Variability in the Southern Ocean ecosystems” and is a contribution to the South African National Antarctic Programme (SANAP). During austral autumn 2009, benthic specimens were collected from 10 stations (from depths of 70 to 295 m) in different regions around the PEI: inter-island shelf (upstream, between and downstream of the islands) and nearshore. Historical data were combined with new data collected during 2009 to assess the long-term trends in the feeding ecology of the benthos in the region of the islands. The stable isotope and fatty acid signatures of the benthic suspension- and deposit-feeding organisms generated during this study suggested that these two communities incorporated both phytoplankton and kelp in their diets. Stable isotope, and to a lesser extent fatty acid signatures, indicated that kelp contributed more to the diets of those organisms in close proximity to the kelp beds (nearshore stations) than those from the inter-island region. Overall, however, pelagic phytoplankton was the dominant food source in the diets of all organisms, even for those living near the kelp beds. Notable exceptions were the sponges and bryozoans, in which kelp and phytoplankton contributed similar proportions to their diets, most likely resulting from a size restricted feeding mode. There were, therefore, no distinct spatial differences in the importance of the various food sources. However, fatty acid compositional data indicated increased food quality between and within the lee of the islands compared to upstream. The organisms collected upstream of the PEI had substantially lower quantities of total fatty acids (TFAs) than organisms of the same species collected from nearshore, open shelf or downstream stations. The increased food quality between and within the lee of the islands was likely a result of the “island mass effect”, which reflects increased phytoplankton concentrations at the PEI. The fatty acid profiles of hyperbenthic shrimp Nauticaris marionis, a key species in the PEI ecosystem, revealed no distinct ontogenetic or spatial patterns. This result is in contrast to the stable isotope analyses, which detected both spatial and ontogenetic differences in the diet of the shrimp. Nearshore shrimp were more ₁₃C-enriched than those from the inter-island region, suggesting increased kelp entering the food web within these regions. In addition, the shrimps demonstrated enrichment in δ₁₃C and δ₁₅N signatures with an increase in size, resulting in a relatively distinct separation of size classes, thus reflecting niche separation through their diets. The fatty acid profiles revealed that the shrimp all contained large proportions of polyunsaturated fatty acids (PUFAs) and essential fatty acids (EFAs), indicating that the quality of food consumed was similar among size class and region despite the niche separation and variation in carbon sources utilised. In addition, diatom and dinoflagellate fatty acids (20:5ω3 and 22:6ω3, respectively) occurred in the highest proportions in N. marionis, highlighting the importance of phytoplankton (indirectly) in their diet. These results represent strong evidence that phytoplankton is an importance food source in the PEI ecosystem. The temporal investigation of isotope signatures in the benthos at the PEI indicated that N. marionis demonstrated an overall depletion in δ₁₃C signatures over the period of 1984 to 2009 (nearshore: -2.55 ‰, inter-island: -2.32 ‰). Overall, the benthic community showed similar depletions in δ13C signatures (from -1.96 to -4.70 ‰), suggesting that shifts have occurred in the carbon signatures at the base of the food web. The depletion in δ₁₃C signatures of the benthos at the PEI most likely reflects increased contributions of smaller slow growing phytoplankton cells (more depleted signatures than large fast growing cells) in the diets of these organisms over time. These diet shifts, in turn, suggest a decrease in productivity has occurred at the islands, likely due to a decreased frequency and intensity of the “island mass effect”. Decreased phytoplankton productivity at the PEI likely results from the southward shift in the average position of the sub-Antarctic Front (SAF), most likely in response to climate change, which in turn promotes flow-through conditions rather than retention at the PEI.

- Description: This study on learner absenteeism takes place in the Namibian context with a focus on the Kavango region, located in Northern Namibia, where absenteeism has been identified as a problem. The intention of the study is to find out the relationship between learner absenteeism and environmental factors. The research question was framed as: How do environmental factors influence learner absenteeism in schools, conceptualised as human activity systems in the Kavango Region (Namibia)? The wider intention of this study is to inform processes that can be put in place to reduce the impact of environmental factors on learner absenteeism, with the ultimate view of improving the quality of education. The literature review provides insight into learner absenteeism in developing and developed nations. It outlines the Namibian policies developed for improving learner attendance and retention of learners in schools, with the view of improving access to school. The study is located within the broader goals of education of Namibia. The research adopts a qualitative interpretive approach, and focuses on environmental factors influencing learner absenteeism in six case studies, which are selected schools in the Kavango province. The study uses a variety of tools such as questionnaires, focus group interviews, observations and interviews as well as document analysis. It uses a combination of inductive and abductive modes of inference in the data analysis. It draws on systems thinking to develop a model that theorises the interrelated roles of different stakeholders, namely, learners, teachers, parents, educational officials (including the regional office and the Ministry of Education). It proposes possible strategies for reduction of learner absenteeism that could contribute towards the improvement of the quality of education. It also mentions the benefits of reducing learner absenteeism in the schools involved in the case study. The findings clearly show that poverty is the main environmental factor that influences learner attendance. The impact of poverty does not, however, occur in isolation; it interacts and has influence over other environmental factors such as alcohol abuse, sickness, lack of parental involvement, lack of motivation from stakeholders and household work. The study also found certain educational factors influenced learner absenteeism, such as teacher attitude, pedagogical styles, and lack of security. The study ends with recommendations to reduce learner absenteeism and recommendations for further research.

- Description: Experience has shown that effective fisheries governance requires a sound understanding of fisheries as systems incorporating both ecological and human dimensions. The Ecosystem Approach to Fisheries requires that the human components of these systems be considered when developing management and governance frameworks. While the potential for inland fisheries to contribute towards societal welfare and the development of rural livelihoods is becoming increasingly apparent, developing South African inland fisheries requires a careful consideration of both their positive and negative impacts, given that they revolve mainly around five of the world‟s top 100 invasive species. This thesis aimed to explore the value of inland recreational fisheries to rural livelihoods in the Amathole District of South Africa, to the regional economy, and to anglers themselves. Three methods were used to isolate this value. Economic impact analysis was used to estimate the combined total economic impact of the 2011 Divisional Tournament (n=31) and the 2012 Amatola Bass Classic (n=100) on the regional economy of the Amathole District, estimated to be R106 625. The travel cost method was applied to data from the 2012 Amatola Bass Classic in order to estimate the social welfare generated by this tournament. The Negative Binomial model, corrected for truncation and endogenous stratification, estimated this value at R 1 960 090. The sustainable livelihoods framework was used to conduct a broad-based analysis of the value of Amatola Wild Trout, the firm which constitutes the fishery surrounding the rural village of Cata. It was found that the fishery had been responsible for a modest pecuniary impact on the community of Cata within its first two years of establishment, although significant improvements in human capital were found to have resulted from the development of the fishery. These results provide insights into the economic dimension of fisheries in the Amathole District, and will prove useful when weighing up the positive and negative impacts of non-native fish species, particularly when informing decisions regarding their potential eradication.

- Description: Recent advances in satellite sensor technology and micrometeorological instrumentation for water flux measurement, coupled with the expansion of automatic weather station networks that provide routine measurements of near-surface climate variables, present new opportunities for combining satellite and ground-based instrumentation to obtain distributed estimates of vegetation water use over wide areas in South Africa. In this study, a novel approach is tested, which uses satellite leaf area index (LAI) data retrieved by the Moderate Resolution Imaging Spectroradiometer (MODIS) to inform the FAO-56 Penman-Monteith equation for calculating reference evaporation (ET₀) of vegetation phenological activity. The model (ETMODIS) was validated at four sites in three different ecosystems across the country, including semi-arid savanna near Skukuza, mixed community grassland at Bellevue, near Pietermaritzburg, and Groenkop, a mixed evergreen indigenous forest near George, to determine potential for application over wider areas of the South African land surface towards meeting water resource management objectives. At Skukuza, evaluated against 170 days of flux data measured at a permanent eddy covariance (EC) flux tower in 2007, the model (ETMODIS) predicted 194.8 mm evapotranspiration relative to 148.9 mm measured fluxes, an overestimate of 31.7 %, (r² = 0.67). At an adjacent site, evaluated against flux data measured on two discrete periods of seven and eight days in February and May of 2005 using a large aperture scintillometer (SLS), ETMODIS predicted 27.4 mm and 6.7 mm evapotranspiration respectively, relative to measured fluxes of 32.5 and 8.2 mm, underestimates of 15.7 % and 18.3 % in each case (r² = 0.67 and 0.34, respectively). At Bellevue, evaluated against 235 days of evapotranspiration data measured using a surface layer scintillometer (SLS) in 2003, ETMODIS predicted 266.9 mm evapotranspiration relative to 460.2 mm measured fluxes, an underestimate of 42 % (r² = 0.67). At Groenkop, evaluated against data measured using a SLS over three discrete periods of four, seven and seven days in February, June and September/October respectively, ETMODIS predicted 9.7 mm, 10.3 mm and 17.0 mm evapotranspiration, relative to measured fluxes of 10.9 mm, 14.6 mm and 23. 9 mm, underestimates of 22.4 %, 11.2 % and 24.1 % in each case (r² = 0.98, 0.43 and 0.80, respectively). Total measured evapotranspiration exceeded total modelled evapotranspiration in all cases, with the exception of the flux tower site at Skukuza, where evapotranspiration was overestimated by ETMODIS by 31.7 % relative to measured (EC) values for the 170 days in 2007 where corresponding modelled and measured data were available. The most significant differences in measured versus predicted data were recorded at the Skukuza flux tower site in 2007 (31.7 % overestimate), and the Bellevue SLS flux site in 2003 (42 % underestimate); coefficients of determination, a measure of the extent to which modelled data are able to explain observed data at validation periods, with just two exceptions, were within a range of 0.67 – 0.98. Several sources of error and uncertainty were identified, relating predominantly to uncertainties in measured flux data used to evaluate ETMODIS, uncertainties in MODIS LAI submitted to ETMODIS, and uncertainties in ETMODIS itself, including model assumptions, and specific uncertainties relating to various inputs; further application of the model is required to test these uncertainties however, and establish confidence limits in performance. Nevertheless, the results of this study suggest that the technique is generally able to produce estimates of vegetation water use to within reasonably close approximations of measurements acquired using micrometeorological instruments, with r² values within the range of other peer-reviewed satellite remote sensing-based approaches.

- Description: Two species of hake (Merluccius capensis and Merluccius paradoxus) account for most of Namibia’s fisheries catch, and they are important secondary consumers in the Benguela Current ecosystem. Inferences on their trophic relationships have been based mainly on stomach content analyses. However, such data are limited temporally because they represent only snapshots of recent feeding, and are quantitatively biased because of variation in the digestion rates of different prey. The principal aim of the thesis was to understand the trophic relationships of two hake species relative to each other, their known prey and top predators (demersal sharks) in the northern Benguela Current ecosystem (Namibia), using time-integrating trophic biomarkers. By using stable isotope (carbon and nitrogen) and fatty acid signatures of their muscle tissues, my overall objectives were to produce new knowledge about 1) hake ontogenic trophic relationships, 2) the contributions of different prey to hake diets, 3) hake dietary differences, and 4) some aspects of hake’s trophic relationships with demersal sharks. Tissues of hake (n=358), their potential prey (n=455), and demersal sharks (n=42) were collected between 2008 and 2012 during demersal bottom trawl surveys off Namibia, for stable isotope and fatty acid analyses.

- Description: The study sought to investigate the management of medical records for healthcare service at the Victoria Public Hospital in the Eastern Cape Province. The objectives of the study were to describe the present records management practices in Victoria Hospital; find out the existing infrastructure for the management of patient medical records at the Victoria Hospital; determine the compliance of patient medical records management in Victoria Hospital with relevant national legislative and regulatory framework; find out the security of patient medical records at the Victoria Hospital. Quantitative and qualitative approaches were employed. The sample was drawn from the service providers and from the healthcare service users. Questionnaires, interviews and observation were used to collect data. The findings showed that Victoria Hospital uses manual records management system in the creation, maintenance and usage of records. In the findings, there were challenges related to misfiling and missing patient folders which sometimes lead to the creation of new patient folders. Also, the study discovered that the time spent in the retrieval of patient folders could negatively affect the timely delivery of healthcare services. The study recommended the adoption of electronic records management system as most public healthcare institutions in the country are rapidly shifting to electronic records management system. The use of electronic records management system is believed to be efficiently and effectively promoting easy accessibility, retrieval of patient medical records and allows easy communication amongst the healthcare service institutions and healthcare practitioners.
