- Description: In Africa, many large and extensive wetlands are hydrologically connected to rivers, and their environmental integrity, as well as their influence on downstream flow regimes, depends on the prevailing channel–wetland exchange processes. These processes are inherently complex and vary spatially and temporally. Understanding channel–wetland exchanges is therefore, indispensable for the effective management of wetlands and the associated river basins. However, this information is limited in most of the river basins containing large wetlands in Africa. Furthermore, it is important to understand the links between upstream and downstream flow regimes and the wetland dynamics themselves, specifically where there are water resource developments that may affect these links (upstream developments), or be affected by them (downstream developments). Hydrological modelling of the entire basin using basin-scale models that include wetland components in their structures can be used to provide the information required to manage water resources in such basins. However, the level of detail of wetland processes included in many basin-scale models is typically very low and the lack of understanding of the wetland dynamics makes it difficult to quantify the relevant parameters. Detailed hydraulic models represent the channel-wetland exchanges in a much more explicit manner, but require relatively more data and time resources to establish than coarser scale hydrological models. The main objective of this study was, therefore, to investigate the use of a detailed hydraulic wetland model to provide a better understanding of channel–wetland exchanges and wetland dynamics, and to use the results to improve the parameterisation of a basin-scale model. The study focused on improving the water resource assessments modelling of three data-scarce African river basins that contain large wetlands: the floodplains of the Luangwa and Upper Zambezi River basins and the Usangu wetland in the Upper Great Ruaha River basin. The overall objective was achieved through a combined modelling approach that uses a detailed high-resolution LISFLOOD-FP hydraulic model to inform the structure and parameters of the GW Pitman monthly hydrological model. The results from the LISFLOOD-FP were used to improve the understanding of the channel–wetland exchange dynamics and to establish the wetland parameters required in the GW Pitman model. While some wetland parameters were directly quantified from the LISFLOOD-FP model results, others, which are highly empirical, were estimated by manually calibrating the GW Pitman wetland sub-model implemented in excel spreadsheets containing the LISFLOOD-FP model results. Finally, the GW Pitman model with the inclusion of the estimated wetland parameters was applied for each basin and the results compared to the available downstream observed flow data. The two models have been successfully applied in southern Africa, with the GW Pitman model being one of the most widely applied hydrological models in this region. To address the issue of data scarcity, during setup of these models, the study mainly relied on the global datasets which clearly adds to the overall uncertainty of the modelling approach. However, this is a typical situation for most of the data scarce regions of the continent. A number of challenges were, however, faced during the setup of the LISFLOOD-FP, mainly due to the limitations of the data inputs. Some of the LISFLOOD-FP data inputs include boundary conditions (upstream and downstream), channel cross-sections and wetland topography. In the absence of observed daily flows to quantify the wetland upstream boundary conditions, monthly flow volumes simulated using the GW Pitman monthly model (without including the wetland sub-model) were disaggregated into daily flows using a disaggregation sub-model. The simulated wetland inflows were evaluated using the observed flow data for downstream gauging stations that include the wetland effects. The results highlighted that it is important to understand the possible impacts of each wetland on the downstream flow regime during the evaluations of the model simulation results. Although the disaggregation approach cannot be validated due to a lack of observed data, it at least enables the simulated monthly flows to be used in the daily time step hydraulic model. One of the recommendations is that improvements are required in gauging station networks to provide more observed information for the main river and the larger tributary inflows into these large and important wetland systems. Even a limited amount of newly observed data would be helpful to reduce some of the uncertainties in the combined modelling approach. The SRTM 90 m DEM (used to represent wetland topography) was filtered to reduce local variations and noise effects (mainly vegetation bias), but there were some pixels that falsely affect the inundation results, and the recently released vegetation-corrected DEMs are suggested to improve the simulation results. Channel cross-section values derived from global datasets should be examined because some widths estimated from the Andreadis et al. (2013) dataset were found to be over-generalised and did not reflect widths measured using high-resolution Google Earth in many places. There is an indication that channel cross-sections digitised from Google Earth images can be successfully used in the model setup except in densely vegetated swamps where the values are difficult to estimate, and in such situations, field measured cross-section data are required. Small channels such as those found in the Usangu wetland could play major role in the exchange dynamics, but digitising them all was not straightforward and only key ones were included in the model setup. Clearly, this inevitably introduced uncertainties in the simulated results, and future studies should consider applying methods that simplify extractions of most of these channels from high-resolution images to improve the simulated results. The study demonstrated that the wetland and channel physical characteristics, as well as the seasonal flow magnitude, largely influence the channel–wetland exchanges and wetland dynamics. The inundation results indicated that the area–storage and storage–inflow relationships form hysteretic curves, but the shape of these curves vary with flood magnitude and wetland type. Anticlockwise hysteresis curves were observed in both relationships for the floodplains (Luangwa and Barotse), whereas there appears to be no dominant curve type for the Usangu wetlands. The lack of well-defined hysteretic relationships in the Usangu could be related to some of the difficulties (and resulting uncertainties) that were experienced in setting up the model for this wetland. The storage–inflow relationships in all wetlands have quite complex rising limbs due to multiple flow peaks during the main wet season. The largest inundation area and storage volume for the Barotse and Usangu wetlands occurred after the peak discharge of the wet season, a result that is clearly related to the degree of connectivity between the main channel and those areas of the wetlands that are furthest away from the channel. Hysteresis effects were found to increase with an increase in flood magnitudes and temporal variations in the wetland inflows. Overall, hysteresis behaviour is common in large wetlands and it is recommended that hysteresis curves should be reflected in basin-scale modelling of large river basins with substantial wetland areas. At a daily time scale, inflow–outflow relationships showed a significant peak reduction and a delayed time to peak of several weeks in the Barotse and Usangu wetlands, whereas the attenuation effects of the Luangwa floodplain are minimal. To a large extent, the LISFLOOD-FP results provided useful information to establish wetland parameters and assess the structure of Pitman wetland sub-model. The simple spreadsheet used to estimate wetland parameters did not account for the wetland water transfers from the upstream to the next section downstream (the condition that is included in the LISFLOOD-FP model) for the case when the wetlands were distributed across more than one sub-basin. It is recommended that a method that allows for the upstream wetland inflows and the channel inflows should be included in the spreadsheet. The same is true to the Pitman model structure, and a downstream transfer of water can be modelled through return flows to the channel. The structure of the wetland sub-model was modified to allow an option for the return flows to occur at any time during the simulation period to provide for types of wetlands (e.g. the Luangwa) where spills from the channel and drainage back to the channel occur simultaneously. The setup of the GW Pitman model with the inclusion of wetland parameters improved the simulation results. However, the results for the Usangu wetlands were not very satisfactory and the collection of additional field data related to exchange dynamics is recommended to achieve improvements. The impacts of the Luangwa floodplain on the flow regime of the Luangwa River are very small at the monthly time scale, whereas the Barotse floodplain system and the Usangu wetlands extensively regulate flows of the Zambezi River and the Great Ruaha River, respectively. The results highlighted the possibilities of regionalising some wetland parameters using an understanding of wetland physical characteristics and their water exchange dynamics. However, some parameters remain difficult to quantify in the absence of site-specific information about the water exchange dynamics. The overall conclusion is that the approach implemented in this study presents an important step towards the improvements of water resource assessments modelling for research and practical purposes in data-scarce river basins. This approach is not restricted to the two used models, as it can be applied using different model combinations to achieve similar study purpose.

- Description: Social media is changing the way business is conducted. Almost five billion videos are watched on YouTube every single day. Social media has an extensive worldwide presence. Out of the total global population of over 7,5 billion people, over 4 billion are internet users. Of these, over 3 billion are active on social media. Social media is very influential in today's decision-making processes. Businesses must integrate social media into their strategies. The purpose of this research was to investigate the use of a novel method, Chernoff Faces, to assess and compare the social media brand images of six insurance companies in South Africa based on social conversation measurement. The intention of research was towards observing existing situations at hand and pointing out the game changers that can provide the industry with a new leap. Social media are multidimensional and understanding them requires tracking different measures simultaneously. Integrating social media into a communication strategy leads to a problem in finding the best way to portray and communicate multivariate data. It is essential to find the best way to represent and transmit the data so that marketing executives can quickly and easily monitor changes in brand images. Previous studies have successfully proved the possibility of using this method to gauge a "snapshot in time." This study took the concept further by closely monitoring the results for a set of brands over a period to account for the dynamic nature of social media. Accordingly, the study was a longitudinal study of 30 days. Data on the insurance companies was collected from Social Mention, a social media search and analysis platform that aggregates user-generated content into a single stream of information. A tool in the statistical software Stata, Chernoff's faces, was used to analyse the results by generating facial expressions to the metrics associated with the social mentions of each of the insurance companies. The resulting facial expressions were then analysed to recognise the more favourable and stable brands and those that need appropriate risk management. Managing Social Media is challenging as managers must always keep it as positive as possible. Brand managers, therefore, need a better tool to gauge the mood in social media conversations due to the fast-changing nature of social media and the importance of social media to business especially insurance.

- Description: This thesis compares the extent to which participatory practices have been used by Caritas Zimbabwe, a mainstream NGO, and the Zvimba Community Share Ownership Trust (ZvCSOT), an indigenous Trust, in Zvimba District, Zimbabwe. Participatory development initiatives are common practice in NGO and government development work in Zimbabwe. The thesis begins with a discussion of two aspects of participatory development (PD). Firstly, PD is discussed in relation to decentralization processes where central government transfers administrative and financial authority to sub-national government units in order to enhance the participation of rural communities in development interventions. Secondly, PD is discussed in relation to the increased role of NGOs in development work. During the 1980s and 1990s, shifts in development thinking resulted in NGOs being perceived as important actors who could attend to the development gaps left by an economically incapacitated state. Both NGOs and sub-national government units were seen to be closer to rural communities and so were thought to be in a better position to enhance the participation of these communities in meaningful development projects. An analysis of the practices of the NGO and CSOT under consideration in this study shows that while there has been much rhetorical commitment to participation, community participation in the development interventions of the NGO and the CSOT is inadequate. In introducing and implementing development interventions, there has been a tendency by both the NGO and CSOT to give priority to organizational preferences over local needs. While recognizing the participatory efforts made by mainstream development NGOs (Caritas in particular) and indigenous Trusts (Zvimba Community Share Ownership Trust in particular) in Zimbabwe, this thesis also considers the impact of other factors on participatory development initiatives. A major observation from the study is that in as much as we expect genuine participatory approaches which include grassroots communities’ inputs from the project’s conceptualization all the way to its evaluation, the challenge is that the elites at the higher level (central government and donor offices) have their own development preferences and interests while the elites at the lower levels (local government and NGO offices) also have their own priorities and needs. Consequently, local communities tend to be confined to implementing development projects foisted on them by elites at the higher level as well as those at the lower level. Worse still, the study shows that elites at the lowest level (community) sometimes hijack or take advantage of the imposed projects. Participation has been stalled by elites at various levels of the participatory development ladder. Thus, unless power imbalances are seriously addressed at all levels, participatory development will remain elusive.

- Description: The Office of the Tax Ombud is critical in the protection of South African taxpayers' rights. The office has only been in existence for a little over five years and to ensure that it fulfils the purpose for which it was established, it must be properly structured. This includes that it ought to be independent from any external influence and manipulation. Any such external influence on the Tax Ombud creates the risk that the general public will lose confidence in the Tax Ombud as an independent recourse. The study, therefore, is designed to review the structure relating to the independence and powers of the South African Tax Ombud. The study assesses and evaluates the legislative safeguards of the structure of the Tax Ombud office in order to determine whether the legislative framework (the Tax Administration Act) safeguarding the Office of the Tax Ombud is adequate to ensure its independence and also to ensure a strengthened structure, without interference in the decision-making process of the office. To achieve this, a comparative analysis was made with selected foreign institutions of Tax Ombudsmen, or equivalent institutions, in order to draw from the best international practice. The study found that the structure of the Office of the Tax Ombud is relatively weak and does not fully provide the legislative powers to protect taxpayers from the well-resourced South African Revenue Service. The study also revealed that most of the institutional features in the structure of the South African Tax Ombud were found to be in line with standard international practice. The study has made recommendations aimed at strengthening the structure of the South African Tax Ombud by suggesting reforms in the legislative framework of the Tax Ombud.

- Description: The Postmasburg Manganese Field (PMF), located in the Northern Cape Province of South Africa, is host to some of the largest deposits of iron and manganese metal in the world. These deposits are restricted to a geographical area known as the Maremane Dome, an anticlinal structure defined by folded dolostones of the Campbellrand Subgroup and overlying ironformations of the Asbestos Hills Subgroup of the Neoarchaean-Palaeproterozoic Transvaal Supergroup. Manganese ores associated with the Maremane Dome have been divided into two major classes in the literature: the Wolhaarkop breccia-hosted massive ores of the Eastern Belt, as well as the shale-associated ores of the Western Belt. The Eastern Belt ores have been classed as siliceous in nature, while the Western Belt deposits are reported to be typically ferruginous. These divisions were made based on their varying bulk chemical and mineralogical compositions in conjunction with their different stratigraphic sub-settings. Presently, both deposit types are explained as variants of supergene mineralisation that would have formed through a combination of intense ancient lateritic weathering in the presence of oxygen, extreme residual enrichments in Mn (and Fe), and accumulations in karstic depressions at the expense of underlying manganiferous dolostones. This study revisits these deposits and their origins by sampling representative end-member examples of both Eastern Belt and Western Belt manganese ores in both drillcore (localities Khumani, McCarthy and Leeuwfontein), and outcrop sections (locality Bishop). In an attempt to provide new insights into the processes responsible for the genesis of these deposits, the possibility of hydrothermal influences and associated metasomatic replacement processes is explored in this thesis. This was achieved using standard petrographic and mineralogical techniques (transmitted and reflected light microscopy, XRD , SEM-EDS and EMPA), coupled with bulk-rock geochemical analysis of the same samples using a combination of XRF and LAICP- MS analyses. Combination of field observations, petrographic and mineralogical results, and geochemical data allowed for the re-assessment of the different ore types encountered in the field. Comparative considerations made between the bulk geochemistry of the different end-member ore types revealed no clear-cut compositional distinctions and therefore do not support existing classifications between siliceous (Eastern Belt) and ferruginous (Western Belt) ores. This is supported by trace and REE element data as well, when normalised against average shale. The geochemistry reflects the bulk mineralogy of the ores which is broadly comparable, whereby braunite and hematite appear to be dominant co-existing minerals in both Eastern Belt (Khumani) and Western Belt (Bishop) ore. In the case of the McCarthy locality, manganese ore is cryptomelane-rich and appears to have involved recent supergene overprint over Eastern Belt type ore, whereas the Leeuwfontein ores are far more ferruginous than at any other locality studied and therefore represent a more complex, hybrid type of oxide-rich Mn mineralisation (mainly bixbyitic) within massive hematite iron ore. In terms of gangue mineralogy, the ores share some close similarities through the omnipresence of barite, and the abundance of alkalirich silicate minerals. Eastern Belt ores contain abundant albite and serandite whereas the main alkali-rich phase in Western Belt ores is the mineral ephesite. In both cases, Na contents are therefore high at several wt% levels registered in selected samples. The afore-mentioned alkali enrichments have been variously reported for both these deposit types. The occurrence of high alkalis cannot be explained through classic residual or aqueous supergene systems of ore formation, as proposed in prevailing genetic models in the literature. Together with the detection of halogens such as F and Br through SEM-EDS analyses of ore from both belts, the alkali enrichments suggest possible hydrothermal processes of ore formation involving circulation of metalliferous sodic brines. Selected textural evidence from samples from both ore belts lends support to fluid-related models and allow the proposal for a common hydrothermal-replacement model to have been responsible for ore formation across the broader Maremane Dome region.

- Description: The Postmasburg Manganese Field (PMF), located in the Northern Cape Province of South Africa, is host to some of the largest deposits of iron and manganese metal in the world. These deposits are restricted to a geographical area known as the Maremane Dome, an anticlinal structure defined by folded dolostones of the Campbellrand Subgroup and overlying ironformations of the Asbestos Hills Subgroup of the Neoarchaean-Palaeproterozoic Transvaal Supergroup. Manganese ores associated with the Maremane Dome have been divided into two major classes in the literature: the Wolhaarkop breccia-hosted massive ores of the Eastern Belt, as well as the shale-associated ores of the Western Belt. The Eastern Belt ores have been classed as siliceous in nature, while the Western Belt deposits are reported to be typically ferruginous. These divisions were made based on their varying bulk chemical and mineralogical compositions in conjunction with their different stratigraphic sub-settings. Presently, both deposit types are explained as variants of supergene mineralisation that would have formed through a combination of intense ancient lateritic weathering in the presence of oxygen, extreme residual enrichments in Mn (and Fe), and accumulations in karstic depressions at the expense of underlying manganiferous dolostones. This study revisits these deposits and their origins by sampling representative end-member examples of both Eastern Belt and Western Belt manganese ores in both drillcore (localities Khumani, McCarthy and Leeuwfontein), and outcrop sections (locality Bishop). In an attempt to provide new insights into the processes responsible for the genesis of these deposits, the possibility of hydrothermal influences and associated metasomatic replacement processes is explored in this thesis. This was achieved using standard petrographic and mineralogical techniques (transmitted and reflected light microscopy, XRD , SEM-EDS and EMPA), coupled with bulk-rock geochemical analysis of the same samples using a combination of XRF and LAICP- MS analyses. Combination of field observations, petrographic and mineralogical results, and geochemical data allowed for the re-assessment of the different ore types encountered in the field.

- Description: This study sought to examine understandings and practices of inclusion as social justice in teacher education programmes in three countries: Canada, South Africa and Zimbabwe. While inclusive education has become an issue of increasing importance globally, contemporary research shows that not much attention has been given to the preparation of teachers as a key element in developing inclusive education systems. Recognising that pre-service teacher education is vital to the success and continued development of inclusive educational practice, the purpose of this qualitative study was to better understand the ways in which inclusion is understood and practiced in the field of teacher education. Using Roy Bhaskar’s (1978) critical realism as a metatheory and drawing on Fraser’s substantive theory of social justice (2008, 2009) and Tronto’s ethic of care (1993, 2013), this study explored the extent to which teacher education faculty and teacher candidates understood and practiced inclusion as an aspect of social justice. The data used in this study was generated through individual and focus group interviews and document analysis in three higher education institutions, one in each of the three countries. In Canada, four teacher educators took part in the interviews while five teacher candidates participated in the focus group. Similarly, in South Africa, three teacher educators and eight teacher candidates participated, and in Zimbabwe, four teacher educators and eight teacher candidates took part in the study respectively. Findings from the study revealed that inclusion still means different things to different people, reflecting contrasting theoretical and ideological orientations from which inclusion is considered, while still remaining a major educational policy concern in all three countries. In the Canadian and South African institutions, inclusion is viewed more in terms of systemic educational change in pursuit of equity, social justice and equal educational opportunities for all learners. In the Zimbabwean institution, the primary focus of inclusion remains creating conditions that make it possible for students with disabilities to overcome barriers to learning and participation by providing specialist educational measures and interventions intended to respond to specific forms of impairment. As a comparative study, it is hoped that this study will contribute to the knowledge of variations and patterns in the ways in which inclusive education is shaped by societal forces such as political, economic and cultural conditions.

- Description: Literature indicates that tax relief measures for persons with disabilities are important as they align with the principle of equity in the allocation of the tax burden. They are a government intervention that assists in decreasing the financial burden of medical care for persons with disabilities. The right of persons with disabilities to an adequate standard of living is contained in the landmark Convention on the Rights of Persons with Disabilities and Optional Protocol, a treaty of the United Nations, which South Africa ratified in 2007. The objective of the research was to provide a comparative study of tax relief measures for persons with disabilities in South Africa with those of Canada and the Republic of Ireland, with a view to identifying potential areas for improvement in South Africa. The requisite information was primarily collected through an extensive analysis of the tax legislation in the jurisdictions. The research found that tax relief measures for persons with disabilities and their families in South Africa are limited when compared with those of Canada and the Republic of Ireland. The comparative study identifies a number of potential tax relief measures for implementation in South Africa.

- Description: Sub-optimal levels of mental workload in automobile drivers is a risk factor for road accidents. However, mental workload as a construct cannot be directly measured. Common indicators of mental workload include heart rate frequency and variability, eye motion and subjective rating tools. Namely, the National Aeronautics and Space Administration Task Load Index (NASA-TLX), its modified, unweighted version called the Raw-TLX, and the Rating Scale of Mental Effort (RSME). Comparisons between the suitability and responsiveness of these mental workload indicators have been almost exclusively examined in driving simulators. However, real-world driving research is important as even high-fidelity simulators cannot capture the complexity of driving scenarios. Hence, this research aimed to compare the suitability and responsiveness of these mental workload indicators in response to real-world driving scenarios. Six participants drove along a set route for an hour while wearing a heart rate monitor and eye tracker. A dashcam was used to capture footage of the different driving scenarios encountered. The set route comprised of driving through the industrial, residential, provincial main road and Rhodes University campus areas. RSME scores were taken during brief stops after driving though each zone. The NASA-TLX questionnaire was administered on completion of the drive and analysed later as the modified Raw-TLX version. The data collected in response to the encountered driving scenarios were sorted into three meta-groupings. (1) Data was segmented according to the different areas that participants drove through. This was termed Area Events and were long duration scenarios of between five and thirty minutes. These driving scenarios were further segmented into two meta-groups with short duration driving scenarios (< 90 seconds). (2) The Common Events meta-group consisted of driving scenarios that were encountered by all participants. These were scenarios were anticipated by drivers. (3) The All Events meta-group was grouped according to all the driving scenarios that were encountered by participants. It consisted of both anticipated and unanticipated driving scenarios of short durations. Data were further analysed using a method of systematically selecting a threshold value for each mental workload indicator. Responses to driving scenarios which surpassed the threshold were considered indicative of an increase in mental workload. The total frequency of higher mental workload events was used as a determiner responsiveness (or ‘sensitivity’) for each mental workload indicator. Mental workload indicators were evaluated for their responsiveness and suitability for assessing mental workload. Results found blink frequency to be a responsive mental workload indicator for all categories of driving scenarios. Blink frequency and duration were the most responsive short duration mental workload indicators. Furthermore, the indicators were able to distinguish between higher and lower mental workload driving scenarios. However, blink parameters are also sensitive to driver fatigue and drowsiness. Further research on distinguishing mental workload from that of fatigue in response to real-world driving was recommended. Pupil diameter, fixation duration, saccade saccade duration and saccade amplitude were found to be responsive short duration mental workload indicators. However, these measures were not determined to be suitable for real-world driving applications. Pupil diameter was confounded by changing illumination levels. Fixation and saccade responses were confounded by the driving task itself as gaze could not be accounted for. For long duration driving scenarios heart rate frequency, heart rate variability: high-frequency power, blink frequency and RSME were found to be responsive and suitable MWL indicators. The Raw-TLX results could not be assessed for responsiveness as it was administered once. However, it was confirmed as a suitable cumulative mental workload indicator in the application of real-world driving. The moderate levels of workload reported by participants agreed with the experimental protocol that prevented inducing sub-optimal mental workload. Blink frequency shows promise as a responsive and suitable mental workload indicator for different types of driving scenarios. More research is needed regarding the assessment of mental workload during short durations using blink frequency and blink duration. For driving durations between five and thirty minutes long, further research into heart rate frequency, heart rate variability: high frequency power, and the RSME was recommended.

- Description: The context of higher education in South Africa which has been shaped by the legacies of the old apartheid system is faced with a paramount task of the continuous process of restructuring and change. In shaping the restructuring and change of the higher education system the concept of transformation has been a constant theme for the post-apartheid government policies. However more recently we have seen the heightened prominence of the concept of change understood as decolonisation of South African higher education – as opposed to “transformation‘. This thesis was concerned with how these concepts of change, “transformation‘ and “decolonisation‘ have been used in debates surrounding higher education in South Africa. The thesis compares and contrasts the ways and context in which they are used. This study of 177 South African newspaper articles taken form independent media stables from the time 2008 to the present provides an analysis of representations of higher education change as “transformation‘ and as “decolonisation‘ evinced in the corpus. This required using both content and framing analysis as a method to analyse the corpus. Three themes emerged from the analysis that are relevant to the comparison between South African higher education institutional change represented as “transformation‘ and South African higher education institutional change represented at “decolonisation‘: the first theme concerns the differences and similarities in how the two terms are defined; the second theme concerns how the two ideas play themselves out when it comes to curriculum change and the final theme concerns the implications of seeing change as “transformation‘ and seeing change as “decolonisation‘ for changing institutional cultures.

- Description: South Africa has the highest number of people living with HIV and AIDS in the world. The HIV pandemic has, and continues to have, negative implications for communities and individuals, especially women, in South Africa and beyond. HIV and AIDS has left women disproportionately more infected and affected than men because of social, cultural and economic factors, leading to the feminisation of HIV. South African NGOs have tried to fill in the gap and to respond to the HIV pandemic, either independently or in partnership with government departments. In this context, the purpose of this thesis is to provide a critical analysis of NGO programmes in Makhanda (in the Eastern Cape Province) to ascertain whether NGOs address the feminisation of HIV and, if so, how. In doing so, the study utilises qualitative analysis with the use of interviews, a focus group discussion and primary documents as research methods. The study concludes that local government in Makhanda has failed to address women’s vulnerabilities to HIV and that it does not provide a sufficiently enabling environment for NGOs in this regard. In addition, inadequate funding from donors, alongside issues of accountability and the failure to engage in HIV programmes from a perspective founded in feminism, were factors found to contribute to NGOs not fully considering women’s vulnerabilities to HIV. Resultantly, NGOs in Makhanda rarely, at least intentionally, address the feminisation of HIV.

- Description: This research presents a case study on the nature of social enterprise in Slovenia. From a resource-based view (RBV), the case study has been used to show what some of the intangible resources are that can be used to promote sustainable social enterprise (SE). The purpose of this research study is to analyse social enterprises in Slovenia in order to establish a framework which other social entrepreneurs can use as the basis from which to operate and achieve competitive advantage. It is an important piece of research for both the process of social enterprise development in Slovenia, as well as to provide ideas and thoughts as to the way forward in this sector for other developing societies. Social enterprise is a developing field and it has been be important to develop cases to begin to explore the concept with real life actualities. The goal is to provide a clearer conceptualisation from which other social entrepreneurs can use as the basis to analyse, plan and improve social enterprise in their own specific contexts. The primary purpose of the study is thus to unpack the core elements that identify social enterprise in Slovenia using the resource-based view. The research aims to understand social enterprise within Slovenia in relation to where it occurs, which are the main industries concerned, and what are the unique resources used to promote sustainable growth. To achieve this, the research was guided by the resource-based view for social enterprise as highlighted by Day and Jean-Denis (2016) as well as that proposed by Bacq and Eddleston (2018). A mind map for a possible route towards improved implementation and understanding of social enterprise in Slovenia, was done through accessing registered social enterprises. This database was from the Ministry of Economic Development in Slovenia. An analysis of 2591 social enterprise, a desktop review of the Slovenian legislation on social enterprise and the unpacking of unique resources available to Slovenian social enterprise was done. This provided a perfect test case to show how the provision of legislation, supportive structures; financial targets, a regional vision and government mentoring social enterprise enhance a contested terrain in Slovenia. Findings highlighted that there have been sustainable successes, but not at the levels expected. It is clear that the government has created various unique resources to build and develop the social enterprise (SE) sector. From an RBV analysis of the social enterprise environment in Slovenia, it is essential to have resources such as legislation, mind-set, in migration (labour) and youth skills be created, monitored and supported. However, there is a need for improved monitoring and tighter implementation of the legislation for social enterprise to provide the solution to destructive social ills.

It is an important piece of research for both the process of social enterprise development in Slovenia, as well as to provide ideas and thoughts as to the way forward in this sector for other developing societies. Social enterprise is a developing field and it has been be important to develop cases to begin to explore the concept with real life actualities. The goal is to provide a clearer conceptualisation from which other social entrepreneurs can use as the basis to analyse, plan and improve social enterprise in their own specific contexts. The primary purpose of the study is thus to unpack the core elements that identify social enterprise in Slovenia using the resource-based view. The research aims to understand social enterprise within Slovenia in relation to where it occurs, which are the main industries concerned, and what are the unique resources used to promote sustainable growth. To achieve this, the research was guided by the resource-based view for social enterprise as highlighted by Day and Jean-Denis (2016) as well as that proposed by Bacq and Eddleston (2018). A mind map for a possible route towards improved implementation and understanding of social enterprise in Slovenia, was done through accessing registered social enterprises. This database was from the Ministry of Economic Development in Slovenia. An analysis of 2591 social enterprise, a desktop review of the Slovenian legislation on social enterprise and the unpacking of unique resources available to Slovenian social enterprise was done. This provided a perfect test case to show how the provision of legislation, supportive structures; financial targets, a regional vision and government mentoring social enterprise enhance a contested terrain in Slovenia. Findings highlighted that there have been sustainable successes, but not at the levels expected. It is clear that the government has created various unique resources to build and develop the social enterprise (SE) sector. From an RBV analysis of the social enterprise environment in Slovenia, it is essential to have resources such as legislation, mind-set, in migration (labour) and youth skills be created, monitored and supported. However, there is a need for improved monitoring and tighter implementation of the legislation for social enterprise to provide the solution to destructive social ills.

A critical analysis of the de-peasantisation process in Nepal with specific reference to the role of state land policies since the 1950s

- Description: The principal objective of this thesis is to offer a critical analysis of the process of de-peasantisation in Nepal since 1950, with a particular focus on the capitalist neo-liberal restructuring of the economy beginning in the early 1990s. The analysis begins by tracing the legacy of feudal land practices and landholdings from the pre-1950 Rana and Shah dynasties. It was under these feudal dynasties that economic and political institutions of extraction first emerged, leading to a landlord-peasant agrarian economy in which peasants (often as tenants/sharecroppers and smallholders) were subordinate to the power nexus between feudal landlords and the ruling dynasties. After 1950, a window of democratic opening was soon interrupted by the formation of the party-less Panchayat system, which lasted from 1960 to 1990. In 1964, a major land reform measure was enacted under the Lands Act, with the goal of enhancing the security and livelihood of the peasantry. However, this process was met with significant resistance by feudal landlords, and actually led to deepening insecurity and the loss of land by peasants, with farmers belonging to lower castes and indigenous groups experiencing this with a greater degree of intensity. The overall result of this period was the beginnings of what is referred to in this study as de-peasantisation. This line of analysis shows that the institutions of extraction remained firmly in place even after the reforms of this period. Finally, the neo-liberal period, which was marked by land titling, the marketisation of land, and the commercialisation of agriculture, represents the late entry of capitalism into Nepal. This period saw the deepening and widening of the process of de-peasantisation, including further loss of peasants’ access to land and a general turn to wage-labour. In this regard, despite propagating the slogan ‘land to the tillers’, the major political parties in Nepal (including the Maoist party) have failed to defend the interests of the peasantry. Some progressive civil society groups have recently sought to do better, but there is also evidence of peasant organisations themselves seeking to resist and oppose the de-peasantisation effects of neo-liberal restructuring. This thesis thus considers the form and extent of de-peasantisation in Nepal, and some responses to it, over an extended period. A broad Marxist-based political economy perspective has been adopted in pursuing the principal thesis objective, but one which argues that there is a symbiotic relationship between economic and political power, such that the latter is not reducible to the former. The thesis draws upon original fieldwork in twenty districts of Nepal, including through the use of a survey, interviews, observations, case studies, and focus group discussions, thus combining both quantitative and qualitative research methods. Based on this fieldwork, it becomes clear that (i) there are major social, economic, and political forces behind the processes of de-peasantisation in the studied districts (and in Nepal more broadly), and that (ii) the Nepali peasantry is becoming increasingly landless, or land-short, and subject to processes of proletarianisation.

- Description: The objective of the turnover tax system is to reduce the administrative burden on micro businesses and to contribute positively to boosting these businesses and the economic growth of South Africa. The over-arching goal of this research was to analyse the South African turnover tax to investigate to what extent the turnover tax system complies with generally accepted principles of a good tax system. The research was conducted within an interpretative post-positivism paradigm, applied a qualitative research methodology, and a doctrinal research method. A detailed review of the literature was conducted to establish the nature of South African turnover tax system and the extent of its compliance with generally accepted principles of a good tax system. The literature review included an in-depth analysis of the South African turnover tax system, an in-depth analysis of generally accepted principles of a good tax system, and an investigation of the extent to which turnover tax system complies with various elements of the principles of a good tax system. It was found in this study that the turnover tax system does not comply with certain of the elements of generally accepted principles of a good tax system and the study proposed several recommendations for the improvement of the turnover tax system. These recommendations include the establishment of training initiatives for micro business owners, reviewing the regulations pertaining to turnover tax and providing digital administration of turnover tax.

A critical appraisal of Saule’s portrayal of women as Amadelakufa (resilient)

- Description: This study seeks to explore how Professor Ncedile Saule’s works Vuleka Mhlaba (2006), Inkululeko Isentabeni (2010) and Libambe Lingatshoni (2017), depict female characters to reveal the inner resilience women embody. It is important to portray females as bold, intelligent and courageous beings as African women are subjected to major patriarchal myths. South Africa prides itself with a progressive Constitution and Bill of Rights that speaks of gender equality and the liberation of all persons. However, in practice women still live under patriarchal bondages and their efforts are side-lined, thus, the essentiality of writings that contributes towards the empowerment of women through displaying their resilience. Women in literature are mostly depicted as subordinate, submissive and emotional. At times they are portrayed as victims. They are very seldom portrayed as heroes or independent beings. They are constantly placed behind a man instead of in front of a man. This research aims to display women as heroes in their own capacity, without having to be dimmed by a man. The researcher decided to utilise writings of a male author so as to provide a different perspective from the norm that most male authors are known to write about in issues pertaining female characters. This is also deliberately done to encourage more male writers to change the mythical narration about women and start admiring their contributions without having them shadow any man. The projection of female resilience through the gaze of a male author gives hope that there are men who see and admire women’s efforts. It also indicates that men realise now that African feminisms are not against men and instead advocate for equality between men and women and recognise the greatness that could come out of a partnership between the two genders. Women’s behaviour and characteristics are mostly socially constructed, hence the need to exhibit the boldness that black women possess, instead of them only being utilised as nurturing sources and household caretakers. One of the purposes of this research study is to illustrate the resilience that women possess and analyse the forms of torment that women in Saule’s chosen novels have experienced and how their experience engenders resilience and a determination to succeed. The women in Saule’s three novels selected for this study break the traditional status quo. The approach that this paper will utilize is that of African Feminisms, focusing on Walker’s Womanism, Ogunyemi’s Africana Womanism, and Stiwanism as the theoretical approaches. This is because African Feminisms concentrates on the issues related to gender, race and class that African women across spectrums face.

- Description: Far-reaching reforms of the TVET college system – including a merger and frequent revisioning of the colleges’ role in the educational landscape of South Africa – have focused renewed attention on this sector. The fact that the sector has been plagued by poor performance – even to the extent that several colleges have been placed under administration – suggests problems at the level of leadership. This study sought to explore key role-players’ understanding of the leadership and management challenges faced by a TVET college and, by examining responses to these challenges, develop a sense of what leadership means in the sector. The study drew on three leadership theories – distributed leadership, transactional leadership as depicted in political models of management, and critical leadership – to help make sense of the findings. A qualitative case study design was used to explore key respondents’ views and lived experiences. The respondents were the principal, two deputy principals, a council member, three campus managers and a programme head. Interviews, questionnaires and document analysis were the chief data collection tools. The study found that critical leadership was the dominant approach at the college. This was revealed in the college leadership’s awareness of broader societal needs and its own role in operating in a socially just manner. College leadership also revealed signs of rejecting the status quo and opposing state control and bureaucracy, in favour of reactionary initiatives. There was limited evidence of distributed and transactional leadership. In fact, ‘leadership’ as such, seemed not to be part of the college discourse, suggesting that the concept and habit of leadership was not broadly discussed, shared and promoted. This sense was strengthened by the fact that at the time of the study, the college was headed by a charismatic and visionary leader. Indeed, the problem at the college seemed to be the Department of Higher Education and Training, which has failed the college in a number of ways.

- Description: This interdisciplinary research located in the research area of forensic linguistics seeks to provide a critique of the monolingual language of record directive for courts in South Africa, while investigating how university language policies contribute the formulation of a monolingual language of record policy for courts, by graduating monolingual LLB students. The research commences with identifying the research problem, goals and objectives and how the language of record policy for courts is linked to university language planning. The research proceeds to an overview of scholarly literature concerning the historical developments of language planning in both the legal system and higher education in South Africa. The theoretical principles concerning the enacting of language legislation and policies is advanced in relation to the constitutional framework. This research furthermore provides a thorough critique of the constitutional framework where the language rights the other related language provisions are discussed in relation to the theory and the application thereof in case law. The research explicates that the language rights of African language speaking litigants is unfairly limited and that access to justice for these litigants is either unattainable or achieved to a lesser extent. The disparities between language, law and power are brought to the fore, where the relevant legislation and language policies fail to determine the language of record in courts as well as legislate the African language requirements for legal practitioners in giving meaning to the constitutional language rights. The language policies of six selected universities is discussed in relation to the legal system’s legislative and policy frameworks, outlining the need to transform the language of learning and teaching and develop the curriculum to support the legal system. In doing so, the shortcomings of the interpretation profession in South Africa are highlighted and the effects thereof on the language rights of litigants. This thesis advances seven African and international case studies, comprising Kenya, Morocco, Nigeria, Australia, Belgium, Canada and India. Each of the case studies provides an in-depth analysis of the language of record/proceedings in courts and the language competencies of legal practitioners and judicial officers in relation to their university education. The African case studies are illustrative that English on the African continent in courts and higher education is dominate and the resultant loss of indigenous languages marginalises people from mainstream society. The international case studies provide two models, Belgium and Canada, which South Africa can emulate, in enacting new legislation and policies and the amendment of current legislation, to ensure bilingual/ multilingual language policies are drafted for courts per province, where the language demographics present majority spoken languages alongside English. Furthermore, where courts interpret language rights and legislative and policy provisions in a purposive manner, where African language speakers are able to, fully realise their rights. Australia and India as multilingual models serve as important case studies where South Africa can learn from what to avoid, how to subvert challenges or adequately address these. These case studies highlight the dangers of a political elite who pursue an English only agenda at the expense of the indigenous languages and the speakers thereof. This thesis in conclusion provides interdisciplinary recommendations that need to be implemented in order to address the language question in South African courts and higher education.

- Description: The thesis provides a critique of sworn statement translations in the South African Police Service. The study is a mixed method study, which is rooted in Translation and Forensic Linguistics. It focuses on translations of two languages, IsiXhosa and English, an activity that was observed by the researcher at the Ndevana Police Station under the Buffalo City Municipality near King William’s Town in the Eastern Cape Province. In addition to the data collection strategies, among others, the study also collected data through the use of questionnaires responded to by the Ndevana Location’s community members. Furthermore, it used a method of consented interviews with the police officers. The main aim of these interviews was to unearth the police officers’ views on whether they require Translators and Forensic Linguists to assist them. Moreover, the other data collection strategy used was the consented recordings of verbal statements made by complainants, facilitated by the capturing of translated written dockets after the reporting of an incident. The police officers involved and who were available in the precinct were Constables, Sergeants, Detectives, Warrant officers and the Captain. The study period was 90 days, and the data presented in the form of graphs is contained in the relevant upcoming chapters. The findings of the study were that there was indeed a need for Translators and/or Forensic Linguists in the precinct, as the statistics revealed, by both the police officers and the community members. An analysis of the transcribed material, the interviews with the police and the verbal statements made by the complainants written by the police were evidence of the need for Translators and Forensic Linguists by the South African Police Services.

The main aim of these interviews was to unearth the police officers’ views on whether they require Translators and Forensic Linguists to assist them. Moreover, the other data collection strategy used was the consented recordings of verbal statements made by complainants, facilitated by the capturing of translated written dockets after the reporting of an incident. The police officers involved and who were available in the precinct were Constables, Sergeants, Detectives, Warrant officers and the Captain. The study period was 90 days, and the data presented in the form of graphs is contained in the relevant upcoming chapters. The findings of the study were that there was indeed a need for Translators and/or Forensic Linguists in the precinct, as the statistics revealed, by both the police officers and the community members. An analysis of the transcribed material, the interviews with the police and the verbal statements made by the complainants written by the police were evidence of the need for Translators and Forensic Linguists by the South African Police Services.

- Description: The primary objective of this study was to assess the pattern of change in neurocognitive performance for adolescent athletes on baseline measures of the Immediate Post Concussion Assessment and Cognitive Testing (ImPACT) test, over five consecutive years, with a view to providing an indication of the optimal interval for repeat baseline testing of high school athletes. Participants were non-clinical, predominantly South African high school athletes in the overall age range 13 to 18 years (N = 108), divided into five groups (Grades 8,9, 10, 11 and 12), and tested at five test intervals. Repeated-measures ANOVA analyses examined differences in score performance across the test intervals for each of the five composite scores of the ImPACT test (Verbal Memory, Visual Memory, Visual Motor Speed, Reaction Time, Impulse Control). For the Verbal Memory, Visual Memory, Visual Motor Speed and Reaction Time composites there were significant neurocognitive score changes between several test intervals. Taking these results into account, in conjunction with substantial variability in performance, it is concluded that there is a need for annual baseline testing throughout the high school years. The secondary objective was to generate normative tables (Means and Standard Deviations) on the ImPACT test for the five participant groups at each of the five test intervals, including data for: the five composite scores (Verbal Memory, Visual Memory, Visual Motor Speed, Reaction Time, Impulse Control); for the twelve subtest scores test that go to make up the composite scores; and for four additional memory subcomponent scores (Word Memory immediate recall, Word Memory delayed recall, Design Memory immediate recall, Design Memory delayed recall). The results provide a clinical and heuristic normative platform for future use with brain injured individuals, which can be used to facilitate clinical interpretations of postconcussion assessments.

- Description: The Namibian Education system, after the country gained independence, introduced various reforms to ensure the attainment of the educational goals of access, quality, equity and democracy in schools. One of the policies introduced to promote democracy in our schools was The Educational Act 16 of 2001, which gave birth to the establishment of Learners Representatives Councils (LRC) in schools. The LRC body is the legal learner leadership body established to ensure learners are represented in school leadership. However, various studies have revealed that this legal body of learners in many schools has been merely ‘rubber-stamping’ decisions made by teachers; learners have had very little input in decisions that affect them as learners. Thus, I was prompted to conduct this formative intervention study on learner leadership at an urban combined school in Namibia. Informed by distributed and transformative leadership theories, the study aimed to develop leadership within the LRC members and the needed expansive transformation regarding leadership practices in school. The intention was for learners to be enabled to practice their democratic right in decision-making processes in matters that concerned their schooling and learning. This study was theoretically and analytically framed by second generation CulturalHistorical Activity Theory. The participants included 12 LRC members, the LRC liaison teacher, the class register teacher, three school management team members and the principal. The research method was a case study, underpinned by the critical paradigm to bring about the fundamental expansive transformation in learner leadership practices at the case study school. This qualitative study was divided into two phases, a contextual profiling phase and an intervention phase. Data were generated through document analysis, observation, questionnaires, focus group interviews and Change Laboratory Workshops. The data were generated to answer the over-arching question: How learner voice and leadership can be developed within a Learner Representative Council (LRC) in an urban combined school, Namibia. The data were analysed inductively and abductively. The key findings were: first, there were a variety of understandings of the concept learner leadership; second, the involvement of LRC members in decision-making processes was limited to involvement in organising extracurricular activities and controlling of other learners at school; third, leadership development opportunities for learners at the case study school were only provided through training at the beginning of the year and the LRC carrying out various activities and roles at the case study school. Several challenges that constrained the LRC voice and leadership development were surfaced and, through Change Laboratory Workshops, the participants of the activity system together with me (the researcher-interventionist), identified the expansive learning opportunities to develop leadership amongst Learner Representative Council (LRC) members. In the final analysis, this study will contribute to the production of knowledge on the concept of learner leadership in the context of Namibia. Fellow scholars, professionals, colleagues and policy makers in education are requested to engage with this thesis to contribute to our understanding of this important aspect of our field and speak back to policy.
