- 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: This study investigated a behaviour of South Africa’s economy towards inflows of foreign direct investment (FDI) from Brazil, Russia, India and China (BRICs) economies, during the period 1997 to 2016. The BRICs bloc was coined in 2001 by then chairperson of Goldman Sachs Asset Management, Jim O’Neil. According to Goldman Sach (2001), the BRICs group was collectively expected to overtake the major economic powers over the span of a few decades. Their growth is expected to shape a new economic order and replace the currently dominant advanced economies. South Africa joined the BRICs bloc in 2010 as the jeweler of the world and as a gateway to Africa. It joined the BRICs group at the time when economic growth was at a sluggish rate, and the savings and investment were at the lowest rate. The country had a high unemployment rate, high levels of poverty and income inequality. On the other hand, the BRICs economies had limited intra-BRICs flows amongst themselves. It is against this background that this study investigated the long run impact of BRICs FDI inflows on South Africa’s economic growth, and the causality relationship between South Africa’s economic growth and BRICs FDI inflows. This study contributes to the body of knowledge of economics in South Africa and the literature on foreign direct investment and economic growth in South Africa. The study employed two cointegration methods to investigate the behaviour of South Africa’s economy towards inflows of foreign direct investment from BRICs economies. These are fully modified ordinary least squares (FMOLS) and dynamic ordinary least squares (DOLS). For granger causality, the study employed Stacked and Dumistrescu Hurlin tests. All the models used time series annual data from 1997 to 2016. The Unit root test results confirmed that the variables were stationary at first difference using panel Im, Pesaran, Shin (IPS) and Levin, Lin, Chu (LLC). The research employs four regressions, first, Economic growth and foreign direct investment (i.e. private sector, banking sector and both sectors), human capital, physical capital, household consumption, government expenditure, exports, and arable land; Second, Employment and foreign direct investment, human capital, physical capital, household consumption, government expenditure, exports, and arable land; third, Economic complexity and foreign direct investment, human capital, physical capital, household consumption, government expenditure, exports, and arable land; finally, Unemployment and foreign direct investment, human capital, physical capital, household consumption, government expenditure, exports, and arable land. The cointegration results for private FDI and economic growth, employment, economic complexity, and unemployment. The results show only economic complexity has significant effect on foreign direct investment and other variables show insignificant results. However, this effect is smaller compared to other growth determinants which are included in the regressions. The cointegration results for bank FDI. These results show more similarities with private FDI results and few differences. However, this effect is smaller compared to other growth determinants included in the regressions. These growth determinants, however, show a positive effect of human capital and household consumption on economic growth which is expected. Other interesting results are exports being positively related with economic growth and unemployment but negative with employment and insignificant with economic complexity. Another one is government spending negatively influence economic growth, employment and positively influence unemployment. But insignificant for economic complexity. Total FDI results and other variables. These results are also similar to private and bank FDI results discussed above. Economic complexity shows significant effect with foreign direct investment, yet other variables are insignificant. . Further results show human capital positively related with economic growth, which is expected. However, physical capital and household consumption negatively affects growth. Another one exports show positive influence on economic growth but negatively related with employment. Yet, insignificant with economic complexity and unemployment. Other results government spending shows negative influence with employment but insignificant with economic growth, economic complexity and unemployment. The results for nonlinearity between the variables under review. The results that employment and economic complexity are nonlinear with foreign direct investment and no nonlinearity between unemployment, economic growth and foreign direct investment. For employment, low levels of foreign direct investment (LFDI_private) adversely affects employment but at higher levels (FDI_private_SQ) is insignificant. For economic complexity, low levels of foreign direct investment are insignificant for economic complexity but at higher levels there is a positive effect of squared foreign direct investment on economic complexity. Further results show that economic growth and employment are nonlinear with human capital, physical capital, household consumption and exports. Physical capital and household consumption adversely affect economic growth, yet positively affects employment. Human capital positively affects economic growth, employment, and unemployment. Exports positively affect economic growth, but negatively affect employment. Further results show nonlinearity between employment and government expenditure. Government expenditure adversely affects employment. Also, economic growth and unemployment show nonlinearity with arable land. Arable land adversely affects economic growth but positively affects unemployment. Nonlinear results for economic growth and economic complexity with foreign direct investment but no nonlinearity in other remaining variables. For economic growth, low levels of foreign direct investment there is a positive effect of foreign direct investment on economic growth, however, at higher levels foreign direct investment are insignificant. For economic complexity, low levels of foreign direct investment are insignificant, yet, higher levels of foreign direct investment there is a positive influence of foreign direct investment on economic complexity. Further results show economic growth and employment that are nonlinear with human capital, physical capital, and household consumption. Human capital positively affects both economic growth and employment. Physical capital and household consumption are adversely affecting economic growth, yet positively affects employment. Further results show nonlinearity between economic growth and government expenditure. Government expenditure adversely affects employment. More results, employment, and unemployment show nonlinearity results with exports. Exports adversely affect employment but positively affects unemployment. Results show economic growth and unemployment that are nonlinear with arable land. Arable land adversely affects economic growth, but positively affect unemployment. Nonlinear results for economic complexity only and other variables show no nonlinearity in the regressions. For economic complexity, low levels of foreign direct investment are insignificant, but at higher levels of foreign direct investment there is positive effect of foreign direct investment on economic complexity. More results show economic growth and employment that are nonlinear with human capital, physical capital, household consumption and exports. Human capital and exports positively affect economic growth, employment, and unemployment. Whereas, physical capital and household consumption adversely affects economic growth and unemployment, yet positively affects employment. Further results show nonlinearity between employment and government expenditure. Government spending adversely affects employment. Further results show nonlinearity between economic growth and unemployment with arable land. Arable land positively affects unemployment, yet adversely affects economic growth. The following section discusses granger causality results. This study also employed granger causality tests. The causality results between economic growth, employment, economic complexity, unemployment, and private foreign direct investment. The causality results show that there is granger causality between economic growth and economic complexity with private foreign direct investment. Whereas, between bank foreign direct investment and other variables there is no granger causality. However, between total foreign direct investment and economic growth and employment there is granger causality. There are a number of policy recommendations that can be drawn from the study. The study results in overall revealed that BRICs (private and bank) FDI inflows had a positive impact on South Africa’s economic growth between 1997 and 2016. The study results suggest that the policy makers should focus the attention on lobbying foreign direct investment from BRICs economies, since this study shows positive impact and relationship between South Africa’s economic growth and BRICs FDI inflows. The BRICs economies should focus on enhancing investment partnership, preventing protectionism, and promoting intra-BRICS flows. In addition, South Africa should eliminate barriers affecting business with BRICs countries. Policy makers should promote the building of new companies (for example Greenfield Investment) so that the economy of South Africa could grow and create employment. , Thesis (MA) -- Faculty of Business and Economic Sciences, Economics, 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: The Government of Zimbabwe is operating using the mantra: ‘Zimbabwe is open for business’. The notion of opening for business requires robust supporting economic infrastructure for enhanced productivity, in the form of reliable supply of electricity, accessible road/railway transport networks and availability of contemporary Information Communication Technology (ICT) infrastructure. The aim of the study was to develop a framework for making financing decisions for public infrastructure in Zimbabwe. The objectives of the study are to: determine the main sources of public infrastructure financing in Zimbabwe; establish innovative finance’s capacity to close the public infrastructure financing gap in Zimbabwe; assess the role played by public-sector accounting in attracting appropriate and efficient mechanisms to finance public infrastructure in Zimbabwe; and ultimately to develop and recommend a framework for selecting suitable and efficient mechanisms to finance public infrastructure in Zimbabwe. According to literature reviewed, public infrastructure is broadly financed by public sector entities using their own resources (internally financed) or through private sector investments and innovative financing instruments (externally financed). When infrastructure is internally financed, the study is theoretically guided by the Public Goods Theory and the Theory of Public Finance and Public Policy. When externally financed, the Risk Return and Pecking Order theories are important. There are many instruments used to finance public infrastructure and one project may be financed using one or more instruments. Therefore, considerations are given to the need for a framework that helps improve the efficiency of the financing decision. The study was designed as a multiple case study that focused on four sectors of economic infrastructure, that is, transport, energy (electricity), ICT as well as water and sanitation. The research used synchronous mixed methods to achieve the objectives of the study. Qualitative research methods addressed the following objectives: a) to determine the main sources of public infrastructure financing in Zimbabwe; b) to establish innovative finance’s capacity to close the public infrastructure financing gap in Zimbabwe; and c) to assess the role played by public-sector accounting in attracting appropriate and efficient mechanisms to finance public infrastructure in Zimbabwe. Whilst to develop and recommend a framework for selecting suitable and efficient mechanisms to finance public infrastructure in Zimbabwe the study combined qualitative and quantitative research methods. Qualitative data was collected through interviews conducted with officials and staff from government ministries, government departments, as well as parastatal enterprises dealing with the four infrastructure types. The same respondents were asked to complete a survey questionnaire used to address part of the objective that developed a framework for public infrastructure financing. Interview data were triangulated using secondary data extracted from reports and financial statements. Some of the secondary data was collected from the World Bank’s development indicators online repository. Qualitative data analysis was done using RQDA, an open-source computer-aided data analysis software. Findings from the study revealed that the main sources of finance for public infrastructure in Zimbabwe are the government through budget appropriations, and concessionary loans from the China Export-Import Bank. There was also finance obtained from multilateral financial institutions such as the Development Bank of Southern Africa and the African Export-Import Bank. The study revealed that there is currently very limited use of innovative financing instruments such as PPPs in financing public infrastructure in Zimbabwe, despite the country having legislation to support such financing arrangements. The innovations in financing observed in the study entail the use of conventional financing mechanisms in unconventional ways. However, there is scope for improving the financing of public infrastructure using innovative financing mechanisms and significantly mitigate the financing gap. Public sector accountants in Zimbabwe are mainly active in financial reporting, although the financial statements for most ministries, government departments and parastatal enterprises had qualified audit opinions from the Auditor General’s office. Public sector accountants are not active in financial management and cost and management accounting responsibilities. As a result, public sector accountants are not adding value to public money through offering advisory services in the efficient investment of public money, as well as financing public infrastructure assets using the most efficient financing mechanism. There is no uniformly applied framework when making financing decisions for public infrastructure in Zimbabwe. Therefore, a framework was developed and is recommended for use by this study. The developed framework entails eight steps that are interrelated and interconnected. Use of the proposed framework requires availability of data about infrastructure projects that have been done in the past. The study recommends that Zimbabwe should ensure a robust framework for protecting private sector investments, which can be achieved by ensuring policy consistency; creating and implementing a legal framework that protects private capital; and having economically viable infrastructure sectors, that are liberalised to allow private sector participation. The Government of Zimbabwe must take deliberate actions that ensure variety of financing options at the disposal of the public sector to lower costs of financing public infrastructure. It is also important to fully operationalise the legislation and policies designed to facilitate the participation of the private sector in financing public sector projects. Such operationalisation entails a decentralisation of the regulations and policies to the provincial and municipal levels. , Thesis (PhD) -- Faculty of Business and Economic Sciences, Accounting, 2021

- Description: The Government of Zimbabwe is operating using the mantra: ‘Zimbabwe is open for business’. The notion of opening for business requires robust supporting economic infrastructure for enhanced productivity, in the form of reliable supply of electricity, accessible road/railway transport networks and availability of contemporary Information Communication Technology (ICT) infrastructure. The aim of the study was to develop a framework for making financing decisions for public infrastructure in Zimbabwe. The objectives of the study are to: determine the main sources of public infrastructure financing in Zimbabwe; establish innovative finance’s capacity to close the public infrastructure financing gap in Zimbabwe; assess the role played by public-sector accounting in attracting appropriate and efficient mechanisms to finance public infrastructure in Zimbabwe; and ultimately to develop and recommend a framework for selecting suitable and efficient mechanisms to finance public infrastructure in Zimbabwe. According to literature reviewed, public infrastructure is broadly financed by public sector entities using their own resources (internally financed) or through private sector investments and innovative financing instruments (externally financed). When infrastructure is internally financed, the study is theoretically guided by the Public Goods Theory and the Theory of Public Finance and Public Policy. When externally financed, the Risk Return and Pecking Order theories are important. There are many instruments used to finance public infrastructure and one project may be financed using one or more instruments. Therefore, considerations are given to the need for a framework that helps improve the efficiency of the financing decision. The study was designed as a multiple case study that focused on four sectors of economic infrastructure, that is, transport, energy (electricity), ICT as well as water and sanitation. The research used synchronous mixed methods to achieve the objectives of the study. Qualitative research methods addressed the following objectives: a) to determine the main sources of public infrastructure financing in Zimbabwe; b) to establish innovative finance’s capacity to close the public infrastructure financing gap in Zimbabwe; and c) to assess the role played by public-sector accounting in attracting appropriate and efficient mechanisms to finance public infrastructure in Zimbabwe.

A problematisation of Afrikaner identity subject positions as found in the coverage of contemporary Afrikaans music in HUISGENOOT magazine discourse

- Description: Through the lens of Foucauldian genealogy, this thesis problematises the subject positions towards Afrikaner identity reflected in contemporary Afrikaans songs covered by Huisgenoot magazine. Such a genealogical exploration thematises the games of truth underpinning the formation of Huisgenoot, highlights its role in solidifying white Afrikaner Nationalist discourse of apartheid, observes its more populist, profit-oriented approach from the 1970s onwards and considers the residual echoing of its former discursive orientation. The song analysis of selected Afrikaans songs/music videos covered in Huisgenoot is guided by the semiotics of Nicholas Cook, such that it frames the analytical question of how such music is driven by conformance, contest and complementation between multi-media elements in ways that make meaning possible. Accordingly, this methodology resonates with the non-essentialising focus of Foucauldian problematisation, premised on critical resistance that makes new responses simultaneously possible. The self-reflexive autoethnographical approach employed, entailing the author’s dialogical engagement with her own ‘Afrikaner self’, similarly facilitates the dynamic interplay between multiplicities. Correlatively, on the one hand, more ‘closed’ and more ‘open’ Afrikaner identity positions reflected within the songs are analysed, as well as seemingly ‘reconciliatory’ / collaborative’ musical manifestations which ultimately revert back to more ‘closed’ identity constructs. But on the other hand, observation of adherence to a ‘white-black’ dichotomy within songs that manifest more ‘closed’ identity positions also leads to consideration of the parallels between the goals of white Afrikaner Nationalism and the current Decolonisation narrative, which is informed by Black Consciousness thought and generated by the ‘Colonisation of a Special Kind’ ANC policy. Both such Decolonisation rhetoric and the countering rhetoric of the Neo-Afrikaner Protest Movement (NAP) are thus identified as metanarratives, underpinned by a ‘white-black’ dichotomy. In this regard, while Huisgenoot’s predisposition towards songs manifesting more ‘closed’ Afrikaner identity positions is considered in terms of its aforementioned profit-oriented endeavour to appeal to its ostensible primary readership, an encouraging increase in coverage of coloured artists is both noted and occasionally seen to overlap with its coverage of songs manifesting more ‘open’ Afrikaner identity positions. Among the latter one may – again in Foucauldian terms – differentiate between songs focussed on an engagement in cross-cultural relations of power, and songs intent on shattering states of domination of power blocks, often through shocking juxtaposition of disparate elements. These more violently dismantling endeavours, it is argued, comprise examples of Foucauldian transversal struggles, although their coverage in Huisgenoot is also attributed to their shock value and/or record sales, rather than their transformational potential. Furthermore, such Huisgenoot coverage is also seen to place more transformationally oriented artists at risk of media ‘domestication’, with its concomitant inhibiting of creativity. Finally, the researcher’s commitment to creative problematisation of her own Afrikaner identity, coupled with acknowledgement of her inescapable textual entrapment, culminates in her acceptance of the continual flux characterising dialogical power relations, before she – in accordance with the Foucauldian methodology employed – presents all ‘conclusions’ in a non-dictatorial spirit of ‘truth creation’, desirous of continual self/other dialogue. , Thesis (PhD) -- Faculty of Humanities, 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: In recent years, Education for Sustainable Development (ESD) has been a significant focus for research pertaining to teacher education and transformative approaches to teaching and learning. However, there has been less specific focus on the implementation of ESD in the context of higher education. This study, therefore, explored the use of an ESD-based teaching and learning approach in an undergraduate Development Studies programme. The focus was on developing a teaching approach that was informed by the principles of ESD and which could assist Development Studies lecturers in creating a more transformative, student-centred environment. This study was a qualitative undertaking, conducted at the Nelson Mandela University’s (NMU) Development Studies undergraduate programme. The ESD-based approach was implemented by two participating lecturers who utilised the approach across four undergraduate classes. Qualitative data were generated through a systematic literature analysis (SLA), exploratory interviews, student exercises and assessments, focus group discussions, and reflective journal entries. The gathered data were then analysed using a framework analysis rubric adapted from the theoretical framework utilised in the study. In addition, the data were coded using the six coding techniques promoted by Saldaña (2013). The findings suggest that the ESD-based approach developed in the study could effectively contribute towards promoting ESD in the Development Studies programme. The findings also suggest that, when properly implemented, the ESD-based approach could assist lecturers in creating a more transformative learning environment where students have greater control over their learning experience. In addition, this study found that students in the selected Development Studies undergraduate programme could benefit from continued exposure to the teaching methods and techniques adopted in the approach. The implementation of the approach also uncovered some of the inhibiting factors that may prevent an ESD-based approach being mainstreamed into the context of higher education. , Thesis (DPhil) -- Faculty of Business and Economic Sciences, Development Studies, 2021

- Description: Infertility remains a major clinical and social problem, affecting approximately one in every ten couples. The implications of infertility range from physical abuse to denial of family property, divorce, psychological problems, such as withdrawal, anxiety and depression to social isolation, scorn, rejection and stigmatisation. The health of infertile couples needs holistic attention because, while their medical and surgical needs are addressed to correct physical and physiological barriers of infertility, their psychological and emotive needs, which constitute the psychosocial aspects of infertility, need to be addressed as well. The current study explored and described the experiences of couples with infertility and primary caregivers who rendered care to couples. The study aimed to develop a best practice psychosocial-cultural care guideline for primary caregivers to enhance the management of couples experiencing infertility in Talensi and Nabdam districts of the Upper East Region in Ghana. The study followed a qualitative design while making use of explorative, descriptive contextual and interpretive ethnographic approaches. The research populations comprised couples experiencing infertility and the primary caregivers who cared for them, consisting of public health nurses and midwives. The research study comprised three phases. In Phase 1, semi-structured interviews, narrative sketching and storytelling were used to collect data on experiences of couples with infertility while semi-structured interviews were used to explore and describe the experiences of primary caregivers who cared for them. The interviews were transcribed and analysed using Tesch’s eight steps of data analysis to make sense of the data collected. The researcher ensured the validity of the study by conforming to the Lincoln and Guba’s approach to trustworthiness by using an independent coder to validate the researcher’s coding. In Phase 2, an integrative literature review was conducted to identify previous guidelines and systematic reviews regarding psychosocial–cultural care of infertility. Relevant guidelines and reviews were selected and critically appraised. Data were extracted and synthesised for the development of a best practice guideline for psychosocial–cultural care of couples experiencing infertility. An independent appraiser critically appraised relevant guidelines to ensure trustworthiness. In phase 3, the findings of Phases 1 and 2 were integrated to formulate a draft best practice guideline for psychosocial–cultural care of couples experiencing infertility. The guideline was reviewed by a six-member expert panel and modified based on their recommendations, suggestions and comments leading to the finalisation of the best practice psychosocial–cultural care guideline for primary caregivers of couples experiencing infertility in the Talensi and Nabdam districts in Ghana. , Thesis (PhD) -- Faculty of Health 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: 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

- Description: Contract compliance has continuously played a vital role in the development of nations globally. It is important, because it enhances the efficiency and success of projects; ensures value for money; mitigates risks and saves a considerable amount of time and resources. Despite its importance, projects continue to fail due to poor communication, untimely deliveries, poor quality deliveries and the lack of a suitable compliance environment. This study helped to address the aforementioned challenges by creating an enabling environment for contract compliance in procuring and disposing entities (PDEs) in state departments in Uganda. The purpose of this study was to determine the enabling factors necessary for contract compliance and how it can be effectively used to assist PDEs in the Ugandan context. This purpose was achieved through a qualitative research approach that provided insights into the need for contract compliance among PDEs and the perceptions thereof; the contract compliance processes; challenges associated with contract compliance and the factors to be considered when creating an enabling environment for contract compliance. Data was gathered from telephonic interviews with twenty one participants and focus group discussions via the Zoom online platform with eight participants, bringing the total number of participants to twenty nine. Participants included auditors, accounting officers, heads of finance departments, heads of procurement departments and procurement officers. Data was collected using an interview guide and analysed by means of content and thematic analyses. A conceptual framework for creating a suitable environment for contract compliance in PDEs was developed. Findings indicate that the critical factors for creating an enabling environment include: communication; reporting; records management; institutional structure; compliance checks; enforcement; a legal and regulatory framework; and evaluation. Other factors include: stakeholder involvement; contract management; funding; openness; ethical orientation; and capacity building. The proposed conceptual framework serves as a valuable resource for researchers and practitioners, especially those involved in public procurement. , Thesis (DPhil) -- Faculty of Business and Economic Sciences, Business Management, 2021

- Description: Physical Education (PE) is vital for the holistic development of Foundation Phase learners. Foundation Phase teachers working in low resource contexts, however, being generalists rather than specialists, struggle to teach PE effectively, even when supplied with programmes by external experts. I was interested in finding out why, and what could be done to help them integrate Fundamental Movement Skills (FMS) into their teaching, to benefit their learners. I proceeded from the hypothesis that teachers should play an active part in their own development, otherwise any Continual Professional Teacher Development (CPTD) would not bring about the change desired. I argued that if CPTD training and support is embedded within their context and based on teaching philosophies that foster teacher transformation, empowerment, and advocacy, then teachers might be more likely to commit to teaching PE. My aim in this study was thus to develop a collaborative process of CPTD with Foundation Phase teachers in low resource schools to enrich their pedagogical content knowledge (PCK) of PE and FMS within their contexts of social disadvantage. I initially adopted a qualitative design, but during this study, I realised that a more participatory approach was needed. I therefore present my study in two phases In Phase One, I answered the question: What are Foundation Phase teachers’ experiences of implementing PE in low resource schools? I did so to inform the design of an appropriately suited CPTD model for Phase Two of this study. I used a qualitative research design situated within the interpretive paradigm. I purposively sampled 24 Foundation Phase teachers to partake in semi-structured interviews. Thematic analysis revealed three broad themes, namely, personal, and systemic barriers to PE, as well as positive responses to challenges. The overlap between themes was significant, highlighting the complexity of teachers’ experiences and perceptions of PE. Teachers’ positive responses emphasised that they possess the creativity and advocacy to overcome challenges posed and necessitated that I adopt a participatory design to work with teachers to develop a collaborative form of CPTD. Phase Two of this study was guided by the questions set by the participating teachers. Ten Foundation Phase teachers from two schools volunteered to be part of the study. In Cycle One they asked: What do we need to learn to be able to effectively implement PE? The findings of Cycle One led them to ask the following question in Cycle Two: How can we improve our confidence to teach PE within our school contexts? Participants did so through collaboratively creating PE lessons which they then implemented and evaluated. The findings of Phase Two highlighted how Foundation Phase teachers can be guided to empower themselves to overcome the barriers to teaching PE that they face in their low resource schools. Based on teachers’ CPTD experiences, I then addressed the third question of this study: What CPTD guidelines can be generated to enable Foundation Phase teachers to improve on and to implement their PCK of PE and FMS at low resource schools? Five CPTD guidelines aimed at collaborative and transformative PE-based CPTD focused on whole school transformation were identified. I provide a graphic depiction of the CPTD guidelines that explains how it can be operationalised. These CPTD guidelines and process model provide valuable knowledge to inform CPTD policy and practice of PE in the Foundation Phase in low resource schools. , Thesis (PhD) -- Faculty of Health Sciences, 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: The purpose of this study was to develop four scenarios for South Africa over the next forty years. The Positive Seed scenario portrays a positive image of hope and determination, with positive institutional innovations, as well as positive innovative learning methodologies. While the Shankar scenario also portrays positive institutional innovations, it is lacking in terms of innovation learning methodologies. The Negative Seed is lacking in both innovation learning methodologies, as well as institutional innovations. Finally, the fourth scenario, that of the ‘What If’ scenario, portrays a scenario whether good innovative learning methodologies exist, or not, but lacks institutional innovativeness. The goal of this thesis was not only to affirm the known and knowable about the skills-development environment, but it is also aimed at exploring its future within the 4IR towards 2060. This was achieved by scenario planning and the Causal Layered Analyses (CLA) methodology, which is designed to help navigate through this creative process. This thesis starts off by identifying the forces of change, which it then combines in various ways to create the set of scenarios about how the future of the skills-development sector could evolve towards 2060. This thesis provides useful insight into drivers for change for the South African skills-development sector and how to anticipate skills-readiness in South Africa within the 4IR towards 2060 in accordance with the CLA and scenario planning methods. This thesis looks at the future of skills-development in South Africa over the next forty years from a decision makers point of view. , Thesis (DBA) -- Faculty of Business and Economic Sciences, Business Administration, 2021

- Description: The purpose of this study was to develop four scenarios for South Africa over the next forty years. The Positive Seed scenario portrays a positive image of hope and determination, with positive institutional innovations, as well as positive innovative learning methodologies. While the Shankar scenario also portrays positive institutional innovations, it is lacking in terms of innovation learning methodologies. The Negative Seed is lacking in both innovation learning methodologies, as well as institutional innovations. Finally, the fourth scenario, that of the ‘What If’ scenario, portrays a scenario whether good innovative learning methodologies exist, or not, but lacks institutional innovativeness. The goal of this thesis was not only to affirm the known and knowable about the skills-development environment, but it is also aimed at exploring its future within the 4IR towards 2060. This was achieved by scenario planning and the Causal Layered Analyses (CLA) methodology, which is designed to help navigate through this creative process. This thesis starts off by identifying the forces of change, which it then combines in various ways to create the set of scenarios about how the future of the skills-development sector could evolve towards 2060. This thesis provides useful insight into drivers for change for the South African skills-development sector and how to anticipate skills-readiness in South Africa within the 4IR towards 2060 in accordance with the CLA and scenario planning methods. This thesis looks at the future of skills-development in South Africa over the next forty years from a decision makers point of view. , Thesis (DBA) -- Faculty of Business and Economic Sciences, Business Administration, 2021

- Description: Mining has been a key driver of socioeconomic change, economic growth and environmental impact for decades. However, the industry’s volatility and its negative social and environmental effects are sources of concern. In this context, the study investigated the stakeholders’ perceptions of Shared Value (SV) within the mining industry of South Africa. This included establishing antecedents and outcomes of SV within the South African mining industry. The study also aimed to fill the research gap and contribute to the existing body of knowledge regarding the mining industry and SV in South Africa. The comprehensive literature review in this study included discussion on the overview of the South African mining industry, theories related to SV, theoretical perspectives on SV, and the experiential studies supporting the study’s hypothetical model. The empirical investigation conducted by means of a survey was undertaken under the unprecedented conditions of COVID-19 pandemic. The primary data was statistically examined in six phases: exploratory factor analysis (EFA); Cronbach’s alpha; descriptive statistics; Pearson’s product correlation; and regression analysis. The ANOVA was also conducted to determine the influence of demographic factors on SV perceptions. The empirical results confirmed that automation and innovation (through three pillars, namely, innovation for value chain inclusivity, automation and business model innovation, infrastructure development) and employment conditions are the antecedents of SV. The study illustrated three approaches of SV: reconceiving the product/service and markets, reimagining value chain productivity and development of the enabling environment. Furthermore, the study revealed competitive advantage and sustainability performance as the outcomes of SV. This study makes a notable contribution throughout management and strategy practices as it provides insightful guidelines for stakeholders to understand how to adapt and enforce SV strategies, while empirical results could also be utilised by the government as a guide to formulate policies and strategies relating to the mining industry. , Thesis (DPhil) -- Faculty of Business and Economic Sciences, Business Management, 2021

- 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: Estuaries are complex systems and should be defined as social-ecological systems. This study investigated whether the Swartkops Estuary was managed as a socialecological system and also argued for the resource to be characterised as a commonpool resource due to its ‘open access’ nature and being utilised by many users. People often live in close proximity to estuarine resources. This means that the ecological component of the estuary cannot be managed separately from the social system. There are feedbacks that result from the interactions taking place between the ecological and social components and these need to be considered. Furthermore, the interactions between humans and estuaries are complex and do not change in a linear, predictable manner. The research methods investigated two research aims: (i) to investigate whether social-ecological systems approaches are currently being adopted in the Swartkops Estuary; and (ii) the sustainable management of the Swartkops Estuary and potentially other estuaries in South Africa. The following research objectives formed the basis of this study: (i) to examine the current management system of the Swartkops Estuary; (ii) to determine and map the social and institutional actors for the Swartkops Estuary; (iii) to analyse the views of local stakeholders, authorities (policy makers) and policy implementers on the use of a social-ecological systems approach in the integrated management of the Swartkops Estuary; and (iv) to illustrate the potential advantages of adopting a social-ecological systems approach for ecosystem services and society. A mixed-method research design was applied in this study using questionnaires, semistructured interviews and focus groups discussions as data collection methods. The ecosystem services approach is one of the accepted approaches that links humans and ecosystems and the results of this study has demonstrated that the habitats of the Swartkops Estuary provide ecosystems systems to various stakeholders. Through the application of the natures’ contribution to peoples lens, this study has shown that estuaries contribute both positively (ecosystem services) and negatively (ecosystem disservices) to people. The findings of this study have revealed that the Swartkops Estuary faces sustainability challenges related to free-riding and the tragedy of the commons dichotomy. The governance of the Swartkops Estuary is weak due to the limited implementation of policy and regulatory requirements. This inadequacy in implementation has led to the overexploitation of living resources in the Swartkops Estuary because the ‘rulesin use’ are not respected and adhered to by users. This study therefore proposes guiding principles and practical implications for each of the following dimensions: (i) social-ecological systems; (ii) common-pool resources; and (iii) governance for integrated sustainable estuarine management. Challenges faced by estuaries are not only of ecological, social or economic nature; they involve a combination of all three. The sustainability of estuaries is therefore complex and requires management and governance that is designed to cope with, and adapt to, the social-ecological system changes. The novel contribution of this study is moving away from the orthodox approaches of examining the Swartkops Estuary by applying the SES approach to assess the governance of the estuary as a common-pool resource. , Thesis (DPhil) -- Faculty of Humanities, Development Studies, 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
