- Description: Today the (Transnational) State Apparatuses of neoliberal capitalism, ranging from educational institutions to mass media and financial institutions, have effectively created and channelled desires towards consumerism, predicated on resource-extractive practices, within the context of what Gilles Deleuze calls societies of control. This control has also intensified in the digital era, particularly through Internet-based technologies which provide increasingly efficient platforms for the escalation of commodification – ironically, despite the reality of ecological crisis being precipitated by the related extractive practices to the point where it now threatens the continued existence of life on earth. , Thesis (MA) -- Faculty of Humanities, School of Language, Media and Communication, 2021

- Description: South Africa’s automotive industry is a vital element in the country’s economy. This sector has been a strategically important sector in South Africa, and it is imperative to ensure not only the sustainability of the automotive sector in the country, but also the continued growth of the industry. This study addressed the determinants of South Africa’s automotive exports to BRICS countries. The main aim of the study is to examine South Africa’s automotive industry trade elasticity to economic performance in BRICS countries. An econometric assessment was done using different estimation techniques, namely Dynamic Panel Data General Method of Moments (GMM) on annual data from 2000 to 2016, quantile regression for the same period, and ANOVA analysis. This study used eight endogenous variables in explaining determinants of South African automotive export to BRICS countries. The results from the GMM technique suggested that only four variables out of eight variables were statistically significant, namely, automotive exports lagged once, corporate tax, research and development (R&D), and real exchange rates. Gross Domestic Product (GDP), Foreign Direct Investment (FDI), trade openness, and R&D all reduced automotive exports in South Africa. Quantile regression provided difference compared to the GMM dynamic panel data analysis. In the panel data analysis, corporate tax was positive, while in the quantile regression only Brazil’s corporate tax had a positive effect on South African automotive exports. FDI results in panel data GMM results were the same as quantile, while other variables results were not consistence with the dynamic panel data GMM results. The ANOVA results suggested that significant differences between BRICS countries impact on South Africa’s automotive exports. The findings indicate that South African automotive exports to BRICS have been proven to be elastic in four variables., namely, automotive exports lagged once, corporate tax, research and development (R&D), and real exchange rates. The South African automotive industry implemented policies such as the Motor Industry Development Programme (MIDP) and the Automotive Production and Development Programme (APDP); however, these policies failed to realise the targets set by the v industry. On the policies regarding automotive exports in South Africa, it is equally important to pay attention to corporate tax in South Africa as well as in other BRICS countries. BRICS economies lack policy synchronisation, hence the adverse impact on South African automotive exports. South Africa’s BRICS counterparts are knowledge-driven economies. Developing a strong human base is required in the sector. In addition, there is a need for BRICS countries to have a free trade agreement (FTA) to enhance trade amongst member states. Having free trade could help to make BRICS economic integration more meaningful to BRICS countries and the region. , Thesis (PhD) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 2021

- Description: The study sought to investigate the effect of using English as a language of learning and teaching on learner academic performance in the senior phase of Mthatha District, Eastern Cape Province. This study employed a mixed-method approach. The researcher used both qualitative and quantitative methods to collect data. The study was conducted in 3 semi-rural senior secondary schools that were conveniently selected. The quantitative part employed Likert-type scale questionnaires that were administered to 10 Mathematics (Math), 10 Natural Sciences (NS) and 10 Social Sciences (SS) teachers making a total of 30 teachers and a total of 30 learners from grades 8 and 9. For the qualitative part, nine (9) teachers and eighteen (18) learners from the selected schools were interviewed. The 18 teachers in three schools were observed as they taught Grade 8 and 9 learners in their respective classes. Qualitative data were, thus, gathered through interviews and observations. Quantitative data was collected using Likert-type scale questionnaires and was analysed using descriptive statistics and Microsoft Excel. The voice recorded qualitative data from the participant’s responses were transcribed and analysed manually through coding, forming categories and themes that were used for data presentation. These are some of the findings: The majority of learners do not understand English, therefore, it was difficult for them to understand the teaching and learning of the selected subjects in Senior Phase (SP) using English as the language of learning and teaching (LoLT); Although the majority of learners reported that they usually use English as a LoLT and their home language when learning the selected subjects, they still struggled to ask and answer questions in English in a classroom and during examinations; Learners who experience difficulties in learning the selected subjects through the use of English as a LoLT in SP, were taught in their home language (isiXhosa) by their teachers; English and isiXhosa, in the form of code-switching, were used when teaching the selected subjects; Inadequate teacher training and preparation made it more difficult for the learners to perform well in the selected subjects. The study recommends that: The Department of Education should conduct enough workshops to help HOD’s and teachers who teach the selected subjects to keep abreast of new developments in these subjects. These should be integrated with appropriate teaching strategies and learning and teaching support materials.

- Description: The President’s power to appoint cabinet members in South Africa constitutes an essential part of the country’s constitutional framework. It is a discretionary power exercised by the President in his capacity as Head of State bestowed on him by the Constitution, which underpins cabinet appointments.The underlying debates in relation to the President’s power to make cabinet appointments lie between justiciability and non-justiciability. In this respect, there are two schools of thought regarding the question whether the exercise of such a power may be the subject of a judicial inquiry, and if so, to what extent. This thesis provides insight into the nature and origin of the President’s power to appoint cabinet members. It also delves deeply into issues raised by the doctrine of separation of powers surrounding the exercise of this power. The core focus of the thesis is on the extent to which the President can be held accountable for making cabinet appointments. The main argument advanced is that because South Africa is a country founded on the principles of constitutional supremacy and the rule of law, every exercise of public power should be subject to the Constitution, including the President’s power to appoint cabinet members. The determination of whether public power is in line with the dictates of the Constitution calls for an independent judiciary, with the power to rule on any aspect of societal disputes. In pursuit of the above, the thesis analyses the constitutional provisions and case law relevant to the President’s powers as Head of State. The research highlights, amongst others, the President’s duty to give reasons for cabinet appointments. On this point it is submitted that the President does have the constitutional obligation to give reasons for cabinet appointments. Comparisons with other jurisdictions on cabinet appointment processes and oversight mechanisms regarding the exercise of that power form the backdrop against which recommendations are made in the thesis. Proposals are advanced for increased legislative oversight in cabinet appointments. Such oversight should focus on inter alia, the President’s duty to furnish reasons for cabinet appointments. The thesis also proposes a constitutional framework in terms of which Parliament plays a role in the selection of appointees to cabinet. The rationale behind this recommendation is the minimising of instances in which the judiciary is accused of overreaching on the powers of the political organs of government. The courts should, however, still retain the power to pronounce whether both the President and Parliament have fulfilled their relevant constitutional obligations in relation to the process of cabinet appointments. , Thesis (PhD) -- Faculty of Law, Public Law, 2021

- Description: An Objective Structured Clinical Examination (OSCE) is a robust method of clinical assessment which, when properly planned and executed, results in a high quality and credible student assessment. However, concerns regarding its uniformity, fairness, objectivity and accuracy have been raised. Concerns regarding the management of the quality of OSCEs at a public College of Nursing in the Eastern Cape were raised by the College’s stakeholders. No best practice guideline had been developed regarding the management of the quality of OSCEs for this College. The aim of this study was therefore to develop a best practice guideline for the management of the quality of OSCEs at a public College of Nursing. The Transformative Pedagogy Theory proposed by Khedkar and Nair was used as a philosophical underpinning for this study. The Joanna Briggs Institute (JBI) model for evidence-based healthcare was used as a theoretical basis for this study. In Phase One, a qualitative, explorative, descriptive and contextual design was used to explore and describe the experiences of nurse educators regarding the management of the quality of OSCEs at a multi-campus public College of Nursing. Semi-structured individual interviews were used to collect data from fourteen (n=14) nurse educators. Thereafter, a qualitative document analysis of fifteen (n=15) external moderators’ reports was conducted to explore the information external moderators shared regarding the management of the quality of OSCEs at a multi-campus public College of Nursing. A document analysis checklist designed by the researcher was used to extract the data from external moderators’ reports. Tesch’s method of data analysis was utilised to analyse the data from the interviews while the data analysis process proposed by Dalglish, Khalid and McMahon was used to analyse the data from the external moderator’s reports. In Phase Two, an integrative literature review was conducted to search, select, extract, appraise and synthesise best practices regarding the management of the quality of OSCEs in health sciences education. The adapted integrative literature review steps, as proposed by de Souza, da Silva and de Carvalho, were utilised to guide this phase. Data of a total of thirteen (n=13) articles were extracted and synthesised. In Phase Three, the findings of Phase One and Phase Two were synthesised, as a basis for informing the development of a best practice guideline for the management of the quality of OSCEs. The National Institute for Health and Care (NICE) and the Appraisal of Guidelines for Research and Evaluation II (AGREE II) frameworks were used as a basis for developing the best practice guideline for the management of the quality of OSCEs at a multi-campus public College of Nursing. The draft best practice guideline was reviewed by eight (n=8) expert reviewers who were experienced in conducting OSCE’s and best practice guideline development. Lincoln and Guba’s principles—namely credibility, transferability, dependability and confirmability were applied to ensure the trustworthiness of the interview data. Wesley’s criteria- namely triangulation, thick description and audit trail were used to ensure the trustworthiness of the document analysis. The principles as stipulated in the Belmont Report were applied in order to ensure the ethical soundness of this study. Findings of the interviews and the document analysis in Phase One revealed that, while there are measures currently in place to facilitate quality in the management of OSCEs in this College of Nursing, there are gaps such as uncertainty in the assessment practices being used and resource constraints that hinder the overall quality of OSCEs. The participants indicated the need for the development of a best practice guideline for the management of the quality of OSCEs at this College. Findings from the integrative literature review in Phase Two revealed three themes, namely: apply quality measures in the preparation and planning phase of OSCEs; apply quality measures in the implementation phase of OSCEs; and apply quality measures in the evaluation phase of OSCEs. For Phase Three, the developed best practice guideline included three recommendations regarding the quality measures that should be applied in each of the three phases of OSCEs. It is recommended for the developed best practice guideline to be further refined, piloted and implemented to be used by nurse educators and other relevant stakeholders Once implemented, the guideline is expected to enhance the management of the quality of OSCEs at the multi-campus College of Nursing and, ultimately, nursing and patient outcomes through quality nursing education and assessment. , Thesis (PhD) -- Faculty of Health Sciences, 2021

- Description: Child health outcomes in Ghana and Sub-Saharan Africa have remained poor compared to other regions of the world. More than half of the global deaths among children under five years of age occur in sub-Saharan Africa. Neonatal and under five child death rates continue to remain high in Ghana, mainly because of the high death rates recorded in the rural areas. Adequate and prompt utilisation of child healthcare services contributes to improved child health outcomes. Despite all the efforts to improve child health, the utilisation of child healthcare services in rural areas in Ghana such as the Nkwanta South Municipality has remained poor. The purpose of this study was therefore to develop strategies that could facilitate the utilisation of child healthcare services by caregivers for their children in need in the Nkwanta South Municipality, Ghana. A qualitative approach, using an exploratory, descriptive and contextual design was implemented for this study. The research comprised the following three phases. Phase One comprised the empirical phase which explored and described the experiences of three groups of participants namely, nurses who rendered child healthcare services in both hospitals and clinics; caregivers of children under five years of age who utilised the available child healthcare services and caregivers of child under five years of age who did not utilise the available child healthcare services. Data was collected through semi-structured interviews conducted with these participants and analysed qualitatively according to the six steps outlined in Creswell (2014:197). Four main themes and 10 sub-themes emerged from the data analysis and were presented and discussed. Phase Two consisted of the compilation of the conceptual framework using the survey list by Dickoff, James and Wiendenbach (1968:423). The conceptual framework was compiled based on the findings of the empirical phase and the WHO Health for All model which was the theoretical framework that underpinned this study. The conceptual framework was also later used as the lens for the development and description of the strategies to facilitate the utilisation of child healthcare services by caregivers for their children in need in Phase Three. Phase Three of the study was the final phase of the research and it involved the development and description of the strategies that could be used by nurses to facilitate the use of child healthcare services by caregivers for their children in need in Nkwanta South Municipality, Ghana. Five strategies were developed and described in this phase. The five strategies were: training and deployment of nurses; capacity building for nurses to support quality child healthcare delivery; resourcing healthcare facilities; community engagement and participation and stakeholder collaboration. The evaluation criteria of Chinn and Kramer (2011:197) were used by six experts to evaluate the strategies. The strategies were evaluated and found to be understandable, clear, simple, applicable and significant to nursing practice. It can thus be concluded that the purpose of the study was achieved since strategies were developed to facilitate the utilisation of child healthcare services by caregivers for their children in need in the Nkwanta South Municipality, Ghana. , Thesis (PhD) -- Faculty of Health Sciences, 2021

- Description: Child health outcomes in Ghana and Sub-Saharan Africa have remained poor compared to other regions of the world. More than half of the global deaths among children under five years of age occur in sub-Saharan Africa. Neonatal and under five child death rates continue to remain high in Ghana, mainly because of the high death rates recorded in the rural areas. Adequate and prompt utilisation of child healthcare services contributes to improved child health outcomes. Despite all the efforts to improve child health, the utilisation of child healthcare services in rural areas in Ghana such as the Nkwanta South Municipality has remained poor. The purpose of this study was therefore to develop strategies that could facilitate the utilisation of child healthcare services by caregivers for their children in need in the Nkwanta South Municipality, Ghana. A qualitative approach, using an exploratory, descriptive and contextual design was implemented for this study. The research comprised the following three phases.

- Description: The thesis presents a framework to integrate social entrepreneurship (SE) into development planning in South Africa. Even though there is no consensus on a universally accepted definition of the term, there is concurrence that SE brings about social change that can influence the overall development of the community. In South Africa, SE is thus conceived of as one of the mechanisms for addressing the wicked and persistent socio-economic challenges that face the country. Social entrepreneurship occurs in areas such as education, health, skills development, youth programmes, rehabilitation, safety, food security, poverty, job creation, human rights activism, environmental issues, arts and culture, among others. However, it remains unclear how SE is integrated into the development planning and implementation processes. Questions of integrating SE into development planning are asked within the context of South Africa as a democratic developmental state that intervenes in the development process. It emphasises the mobilization of and engagement with all sectors towards the achievement of its development objectives as articulated in the national development plan (NDP). Also, government recognizes organizations in the social enterprise sector (such as NPOs and NPCs) as stakeholders and development partners who deliver relevant services towards the achievement of these development objectives. However, there is a lack of framework to mobilize and integrate the social enterprise sector and SE into the development planning process. Social entrepreneurship, therefore, tends to occur in insolation from other development programmes. , Thesis (PhD) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 2021

- Description: The research claims that curriculum in Uganda is too westernized to the extent that indigenous Ugandan social ethics which informed pre- colonial curriculum have been totally neglected. Consequently, there are many learned but few socially educated persons in the country. Findings highlighted that teacher educators supported the integration of relevant indigenous knowledges into curriculum because indigenous knowledge is directly linked to the environment within which Ugandan students live, studies and operates after studies. They also believed that IUSEs provides a bedrock for professional conduct to flourish and thus, must be treated as an important component of the curriculum. However, though participants acknowledged the advantages of integrating IUSE into curriculum, they identified a number of obstacles to the integration of IUSEs. For instance: lack of consensus of IUSEs among the fifty-six tribes in Uganda; lack of support by the civil service deployment policy. Some confessed to the lack of adequate knowledge about IUSEs; the feeling of cognitive imperialism that is still possessed by some teacher educators and others. Among the strategies to be used for successful integration, teacher educators highlighted the need for collaborative efforts among all stakeholders, adopting the use of local languages as a medium of instruction and others. Data also revealed that the EFC currently aims at professional mentorship and giving employable skills to the students. The Such a situation manifests itself in the degeneration of ethical values by many Ugandans. This study examined teacher educators’ perspectives on integrating IUSEs in an Education Foundations curriculum (EFC). I used the decolonization theory, anti-colonial theory and indigenous knowledge discursive framework as lenses that framed the study. The findings from the study have implications for formulation of an education philosophy that is anchored in a national philosophy should be designed to guide curriculum designers in Uganda. The study further recommended that NCHE should compel all universities to integrate IUSEs into curriculum treating IUSEs as part of the minimum standards that must be satisfied before program accreditation. , Thesis (PhD) -- Faculty of Education, 2021

- Description: As detections of gravitational waves (GWs) mount, the need to investigate various effects on the propagation of these waves from the time of emission until detection also grows. We investigate how a thin low density dust shell surrounding a gravitational wave source affects the propagation of GWs. The Bondi-Sachs (BS) formalism for the Einstein equations is used for the problem of a gravitational wave (GW) source surrounded by a spherical dust shell. Using linearised perturbation theory, we and the geometry of the regions exterior to, interior to and within the shell. We and that the dust shell causes the gravitational wave to be modified both in magnitude and phase, but without any energy being transferred to or from the dust. This finding is novel. In the context of cosmology, apart from the gravitational redshift, the effects are too small to be measurable; but the effect would be measurable if a GW event were to occur with a source surrounded by a massive shell and with the radius of the shell and the wavelength of the GWs of the same order. We extended our investigation to astrophysical scenarios such as binary black hole (BBH) mergers, binary neutron star (BNS) mergers, and core collapse supernovae (CCSNe). In these scenarios, instead of a monochromatic GW source, as we used in our initial investigation, we consider burst-like GW sources. The thin density shell approach is modified to include thick shells by considering concentric thin shells and integrating. Solutions are then found for these burst-like GW sources using Fourier transforms. We show that GW echoes that are claimed to be present in the Laser Interferometer Gravitational-Wave Observatory (LIGO) data of certain events, could not have been caused by a matter shell. We do and, however, that matter shells surrounding BBH mergers, BNS mergers, and CCSNe could make modifications of order a few percent to a GW signal. These modifications are expected to be measurable in GW data with current detectors if the event is close enough and at a detectable frequency; or in future detectors with increased frequency range and amplitude sensitivity. Substantial use is made of computer algebra in these investigations. In setting the scene for our investigations, we trace the evolution of general relativity (GR) from Einstein's postulation in 1915 to vindication of his theory with the confirmation of the existence of GWs a century later. We discuss the implications of our results to current and future considerations. Calculations of GWs, both analytical and numerical, have normally assumed their propagation from source to a detector on Earth in a vacuum spacetime, and so discounted the effect of intervening matter. As we enter an era of precision GW measurements, it becomes important to quantify any effects due to propagation of GWs through a non-vacuum spacetime Observational confirmation of the modification effect that we and in astrophysical scenarios involving black holes (BHs), neutron stars (NSs) and CCSNe, would also enhance our understanding of the details of the physics of these bodies. , Thesis (PhD) -- Faculty of Science, Mathematics (Pure and Applied), 2021

- Description: The last 30 years since the early 1990s has seen the heightened promotion of organic farming as a sustainable farming option in Zambia. The main objectives of this research study were to carry out an analysis of organic farming systems in order to understand factors affecting adoption, as well as reasons why some organic farmers discontinue using the approach. The study involved four districts in Zambia: Mazabuka, Chikankata, Lusaka and Chongwe. Specifically, the research investigated challenges and limitations of organic agronomic practices, and analysed factors that influence adopters and disadopters of organic agriculture. Primary data were collected through interviews and by administering semi-structured questionnaires. The research population comprised approximately 250 farmers adopters and disadopters, with the sample size being 50 farmers chosen across four districts using systematic random sampling methods. Additionally, five observation research field trials were conducted in order to gather practical data on individual farmer’s crop management practices. Farmers adopting and maintaining organic methods reported several reasons for embracing the system, some of which are: organic farming is regenerative; it is environmentally responsible; it uses manure, believed to help build healthy soils rich in organic matter with better nutrient and moisture holding capacity; pesticides and synthetic fertilizers are not used, reducing the levels of toxic residues in organic products which ultimately promotes health. Labour constraints, pest and disease challenges and weed problems were some of the reasons for disadoption. Data showed that disadopters had lower education (48% had primary education), were older and with slightly more children. Although there were more women adopting organic agriculture compared to men, the difference was small 56% and 44% women and men respectively. Among disadopters there were more women (67%) compared to men (33%). Overall, the study results suggest that promotion of organic agriculture should be encouraged through liaison with government departments such as the Zambian Department of Agriculture to include organic agriculture when developing policies. In general, organic farmers have positive opinions concerning the benefits resulting from organic agriculture. Organic farmers should enjoy equal opportunities to conventional agriculture in the provision of extension services, input support, infrastructural development, access to financial resources to procure farm machinery, and equipment and most important of all, they should get fair prices for their organic produce and products. , Thesis (PhD) -- Faculty of Science, School of Environmental Sciences, 2021

- Description: Unequivocally, the traditional male circumcision as rite of passage in South African communities has been embraced for its role in shaping the behaviour among the initiates. This rite was highly valuable during the yesteryears as the traditional male circumcision initiates portrayed compliance with the society’s moral codes and cultural goalposts. Inopportunely, on the other hand, during the contemporary epoch this rite of passage and the cultural underpinnings embedded in it appear to be eroding and shifting from the initial purpose of inculcating good behaviour and morals. This study seeks to compare the behaviour of the yesteryears’ traditional male circumcision initiates and those of the contemporary epoch in Cala, Sakhisizwe Local Municipality and Mdantsane, Buffalo City Municipality in Eastern Cape. This study aimed to achieve the following objectives: (i) to explore the policy differences informing TMC practices in yesteryears and in the contemporary epoch; (ii) to identify the similarities and differences between the behaviour of the contemporary initiates and those of yesteryears; and (iii) to establish the environmental factors motivating the change of the behaviour apparent among the contemporary initiates as well as those of the yesteryears. This study is underpinned by the socio- cultural perspective, anomie theory, and social learning theory. Methodologically, this study was qualitative in nature, where the data was collected through one-on-one in-depth interviews, focus group discussions, and Key informants interviews. An interview guide with open-ended questions was used to collect the data. A sample size of forty (40) participants was purposively selected for interviews. The data collection process was cross- sectional in design. Content analysis was employed to analyze the data and findings were presented thematically. The study established policy differences informing TMC during the yesteryears and the contemporary epoch, in that the yesteryears’ policy environment was culturally grounded; while the contemporary one’s is informed by the current national constitution and human rights perspectives. In relation to the policy issues, the study further established elements of illusionary interpretation of rights by the contemporary TMC initiates; poor implementation of policy guiding TMC practice. Further, the study revealed behavioural and morality differences between the yesteryears’ and the contemporary TMC initiates. For instance, the yesteryears’ TMC initiates were reported to be more responsible and well- mannered as compared to the contemporary ones. The shortfalls in expected behaviour and morality for the contemporary TMC initiates were attributed to modernization, and education in the contemporary initiation schools, which does not meet the societal expectations. On the environmental factors motivating the change of behaviour of the TMC initiates; Yesteryears’ TMC initiates complying with moral codes and cultural goalposts; Non-compliance to the moral codes and cultural goalposts by the contemporary TMC initiates; Culture of alcoholism during the contemporary epoch. Based on these findings, this study recommends that the government of South Africa should augment the existing TMC policies to ensure that traditional male circumcision as rite of passage achieves its socio-cultural objective of shaping behaviour and morals. The study further recommends training for traditional nurses “amakhankatha” and traditional surgeons “iingcibi”; and hosting cultural events for cultural resuscitation. The conclusions of this study state that the government must work hand in hand with cultural custodians to ensure that traditional male circumcision practice shapes good behaviour and morals of the initiates. This is because glaring gaps associated with the rite. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2021

This study is a step in the right direction as it pragmatically attempts to find a constructivism-driven pedagogical strategy that would optimise the attainment of the learning goals of Physical Sciences learners in their various academic settings. To accomplish the research aim, a mixed methods design, in which a non-equivalent (pre-test and post-tests) control-group quasi-experimental design was adopted for quantitative data collection and analysis, and an exploratory case study was adopted for qualitative data collection and analysis. The intervention in the experimental group was case study teaching, whereas in the control group it was the traditional lecture method of teaching science. The topic from the syllabus on which case study teaching was tested was Electricity and Magnetism. The population of the study was all Grade 10 learners studying Physical Sciences in the secondary schools of Sekhukhune East District. The sample consisted of 122 learners from four schools (70 learners from two rural (29 for experimental group and 41 for control group) and 52 from two urban schools (30 experimental group and 22 control group)). Two schools were treated as the experimental groups and the other two as control groups. A multistep sampling process was implemented in selecting the participating schools. Quantitative data was collected using a reading comprehension test, Critical Thinking in Electricity and Magnetism (CTEM) test and a summary writing task that was marked using a Holistic Critical Thinking Scoring Rubric (HCTSR) that was developed by Facione and Facione (1994) and analysed through both descriptive (means) and inferential (two-tailed t-test, Mann Whitney U test and effect size) statistics computed through PSPP statistical pack. Qualitative data was collected through classroom observation (participant observer) in which field notes were kept and face-to-face interviews were conducted, tape recorded and transcribed for analysis. Qualitative data was analysed thematically. , Thesis (PHD) -- Faculty of Education, 2021

- Description: Psychological assessment forms part of Roman Catholic seminary admissions in Southern Africa. The present study sought to explore and describe the perceptions and experiences of the role, purpose, and nature of the use of psychology in Roman Catholic seminary admissions in the territory of the Southern African Catholic Bishops’ Conference. A qualitative research design was selected, which utilised the grounded theory method. Church authorities and clinicians, recruited by means of purposive snowball sampling, were interviewed in individual semi-structured interviews. The findings were interpreted in relation to the narrative of a vocation to the Roman Catholic priesthood, international practice guidelines, as well as literature regarding the context of the Southern African Roman Catholic Church. Proposed guidelines for this process in Southern Africa were generated based on the experiences of the participants and this iterative process of thematic analysis. Potential guidelines, grounded in the research data, emerged in the following focus areas: the vocation to the priesthood, contextual and systemic factors, the clinician, the assessment process, factors to be assessed, the psychological report, the decision to admit to seminary, feedback, and psychology in formation. These are recommended to the Southern African Catholic Bishops’ Conference in draft form to be implemented in a participatory manner. , Thesis (PhD) -- Faculty of Health Sciences, 2021

- Description: This study examined the implementation of Tourism curriculum in Secondary Schools in Fort Beaufort Education District in the Eastern Cape. The study arose from a concern that despite the Government of the Eastern Cape organizing workshops to facilitate the implementation of Tourism curriculum for secondary school teachers, research has shown that teachers have not improved their classroom practice. It discussed the concept of Tourism curriculum implementation and highlighted problems militating against curriculum implementation at secondary school level. The researcher adopted the mixed method methodology which is embedded in the post-positivist research paradigm. The post-positivist research paradigm explains the way things are and views objectivity as an ideal that can never be achieved, however research should be conducted with greater awareness of subjectivity. By combining qualitative and quantitative methodologies, it assisted the researcher to strike a balance and avoid being subjective on issues of teacher capacity, teaching strategies and assessment, availability and use of resources and support and monitoring. The research methods used in this study include questionnaires, interviews, document analysis and observations. The findings of the study showed that there are limitations in the implementation of Tourism curriculum because of lack of capacity of School management Teams and teachers who are implementing NCS Tourism. Although the teaching strategies and assessment are stipulated in the curriculum document teachers are not using appropriate methods and assessment. Moreover, there are crucial resources and facilities provided by SMTs and the Department of Education to implement Tourism curriculum, inadequate compared to those provided for other subjects. Moreover there are limitations in terms of support (including training) and monitoring systems which are in place to enable the implementation of NCS Tourism. Possible areas for future research were highlighted and recommendations were made, for example the researcher recommends teachers to be trained adequately in order to effectively implement the Tourism curriculum. Teachers should be encouraged to use new learner-centred teaching strategies and resources should be provided in all secondary schools through the combined effort of the government, Fort Beaufort Education district and the School Management Teams (SMTs). Support and monitoring systems should be in place for proper implementation of Tourism curriculum. Tourism industries should contribute through provision of instructional materials and teachers as implementers of the curriculum should be involved in decision-making and curriculum planning. The government should employ enough teachers qualified to teach Tourism. On the other hand subject advisors should be adequately trained to enable them to provide relevant support to teachers in Fort Beaufort secondary schools. All stakeholders should be involved in fostering skills and capacities at local level to develop sustainable Tourism and local development in an integrated way. The study identified a possible an alternative model for the implementation of Tourism curriculum. , Thesis (PhD) -- Faculty of Education, 2012

- Description: This study explored the change relation of multi-temporal land-use/land-cover (LULC) conditions in order to determine how they contribute to change in surface runoff volumes and peak discharge, in an effort to predict flash flooding within the Jukskei River catchment. The research is divided into three main parts: (1) LULC change modeling, (2) rainfall-runoff modeling, and (3) flash floods prediction. Three multi-temporal satellite images of Landsat-5 MMS (1987), Landsat-5 TM (2001) and Landsat-8 OLI (2015) were used for LULC modeling. The analysis of the LULC model revealed that there is a continuous increment in built-up area, from 37.7% to 56.2%, in the expense of other LULC classes for the 28-years preceding this study (i.e., 1987 to 2015). Rainfall-runoff model output results revealed that, for these 28 years, there has been an increase in surface runoff due to change in LULC by 21.5%, 32.9% and 45.5% for 1987, 2001 and 2015, respectively. Due to an increase in surface runoff volume and impervious surface over time, the analysis of HEC-RAS/GeoRAS showed that floodplain extent, flood depth, flood velocity, depth-velocity and the level of damage increases especially in low elevation areas and areas at closed proximity to the Jukskei River. Thus, the building structures and infrastructures are at risk of being affected by flash floods during the rainy season. The findings of this study are expected to be used as basic data for the identification of causative factors of flash floods, areas that generate high surface runoff volume, and the prediction of flash floods within the catchment in future. The flood damage maps developed in this study will be useful to policy-makers and the relevant authorities, as well as to local residents, in finding suitable measures for residential development along the floodplain while reducing flood risk in the study area. , Thesis (PhD) -- Faculty of Science, School of Environmental Sciences, 2021

- Description: While considerable progress has been made regarding access to higher education in South Africa for previously excluded and disadvantaged students, great challenges are experienced in terms of student well-being. One of the key factors contributing to students’ ability to complete their studies successfully is food-related challenges. Various programmes have been introduced at institutions of higher education to assist and support students who lack funds for food. However, these programmes are characteristic of the welfarist model, as it is often based on needs, short-term by nature, and dependent on external resources. Furthermore, it reduces students to the role of passive beneficiaries. This research answers the question of how student hunger can be addressed through co-generating a people-centred approach at one higher education institution in South Africa. The study was underpinned by Sen’s capabilities approach to enable a theoretical understanding of the issue of student hunger. Additionally, Korten’s people-centred development provided the value base of the study to place students at the centre of the problem-solving process. An approach to student hunger that would be participative, student-centred, and enhancing nutritional capabilities was invited. Situated within the critical paradigm, I employed the participatory action research design to facilitate a process whereby students critically questioned the issue of hunger and took action to address the issue. Eight students from various study fields volunteered to co-research the issue of student hunger. Over the period of one year, we generated data using different methods (including photovoice, community self-survey, workshops, purposeful group discussions, focus group discussions, and my reflective notes). We applied cyclical processes to plan, implement, and reflect on actions intended to address student hunger. Through a combination of collaborative and individual processes of data analysis, we responded to four subquestions through four phases, which culminated in the co-construction of a people-centred approach to student hunger. Students’ conceptualisations of student hunger revealed two types: hunger of the stomach and hunger of the mind. The cyclical relationship between the two types infers that nutritional well-being is not achieved adequately when students have the means to acquire food. Choices regarding the utilisation of the available means also need consideration. The findings revealed that students apply the conscientisation framework in the ways that they plan to address student hunger. Applying value-driven processes, actions entailed physical dialogues with groups of people. The approach developed in this study offers strategies for the stakeholders who attend to student hunger, to collaborate and make contributions towards comprehensively resolving the complex issue. It primarily could be useful to institutions of higher education as the suggested coordinators of a collaborative structure. A second part of the developed approach puts forward a strategy to address the financial capabilities of students. The study contributes a consideration to constraints that stem from students’ mindsets and adoption of a prevailing culture that maintains student hunger. This demonstrates that resolutions to addressing student hunger might be more effective and sustainable if the context, views and participation of people experiencing the hunger are considered. , Thesis (PhD) -- Faculty of Health Sciences, 2021

- Description: The researcher conducted a sociological investigation into the persistence of child labour in the fishing communities of Uganda, specifically in the Ssese Islands, Kalangala District, on the Kisaba and Nakibanga landing sites situate in Bukasa. The study aimed at investigating the sociological aspects of persistent child labour practices in the fishing communities. The study employed a qualitative research method with a descriptive case study design, utilising an interpretive paradigm. The case study design facilitated the researcher’s investigation into child labour practices in their natural settings. The study employed mainly in-depth interviews, focus group discussions and observations for data collection. Data analysis was performed utilising the ATLAS.ti computer software package to identify the sociological factors involved with employing child labour. The Various themes emerged from the data analysis. The study established that despite the Ugandan Government domesticating all the UN/ILO Conventions on Rights of a Child and Worst Forms of Child Labour, the OAU Charter on Child Rights and Welfare and also instituting legal frameworks at national level, the practice of using child labour persists. The findings disclosed that economic, sociological and structural factors appear to perpetuate child labour in the fishing communities. Economic factors such as poverty, unemployment or underemployment, then sociological aspects such as men abandoning their helpless families on landing sites as they follow the fish according to seasons. Furthermore, the community attitudes such as low value for education, child labour being a normal trend and part of apprenticeship for the children. Again, there are structural issues such as the inadequate implementation and the weak enforcement of the legal frameworks, including insufficient infrastructures such as schooling facilities. These factors appear to perpetuate child labour in the fishing communities. The study concluded that there is an urgent need to address the issues associated with the persistence of child labour in the fishing communities. The study recommends employing a holistic multipronged approach through bottom-up participatory planning and integrating stakeholders at various levels. This could enhance efforts and share ideas and resources that can result in effective operations in order to eliminate child labour in the fishing communities. , Thesis (DPhil) -- Faculty of Humanities, 2021

- Description: A large part of this computational study focussed on selectivity patterns for 4-penten- 1-oxyl radical 1,5- and 1,6-cyclisations and for those of analogous 5-hexenyl, 4- penten-1-aminyl, 4-penten-1-iminyl and 3-phenylpropan-1-oxyl radicals. The study furthermore included cyclisation reactions of the radical cations of 4-penten-1-ol and 3-phenylpropan-1-ol. Calculations were performed for all applicable species involved in the two cyclisation modes studied, i.e. 1,5- and 1,6-cyclisation. These species included radical and radical cation precursors, as well as relevant radical transition state structures and radical adducts. All cyclisation systems investigated used the Density Functional Theory (DFT) functional B3LYP with a combination of eight basis sets. Each basis set used was a progressively higher level of theory than B3LYP/6-31G* which was used as a starting point. Cyclisations for unsubstituted species, e.g. the 4-penten-1-oxyl radical 1,5- and 1,6-cyclisations, were also simulated using the ωB97X-D and ωB97X-V functionals which account for dispersive effects. The same set of eight basis sets were used with these two functionals. , Thesis (PhD) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2021

- Description: A large part of this computational study focussed on selectivity patterns for 4-penten- 1-oxyl radical 1,5- and 1,6-cyclisations and for those of analogous 5-hexenyl, 4- penten-1-aminyl, 4-penten-1-iminyl and 3-phenylpropan-1-oxyl radicals. The study furthermore included cyclisation reactions of the radical cations of 4-penten-1-ol and 3-phenylpropan-1-ol. Calculations were performed for all applicable species involved in the two cyclisation modes studied, i.e. 1,5- and 1,6-cyclisation. These species included radical and radical cation precursors, as well as relevant radical transition state structures and radical adducts. All cyclisation systems investigated used the Density Functional Theory (DFT) functional B3LYP with a combination of eight basis sets. Each basis set used was a progressively higher level of theory than B3LYP/6-31G* which was used as a starting point. Cyclisations for unsubstituted species, e.g. the 4-penten-1-oxyl radical 1,5- and 1,6-cyclisations, were also simulated using the ωB97X-D and ωB97X-V functionals which account for dispersive effects. The same set of eight basis sets were used with these two functionals. , Thesis (PhD) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2021
