The obligation of South Africa to provide social security to refugees and asylum seekers during the COVID-19 pandemic
Get PDFCovid-19 a novel pandemic, has wreaked havoc globally, threatening the livelihoods of all, including refugees and asylum seekers. Like all other countries globally, South Africa has gone to great lengths to mitigate the challenges that this pandemic has caused. However, it is far from clear whether these responses are according due regard to the rights of some of the most vulnerable in society, amongst which are refugees. This thesis deals with South Africa’s obligation to provide social security to refugees during the Covid-19 pandemic. It specifically assesses whether South Africa's responses to the Covid-19 pandemic were in adherence to fundamental refugee law principles relevant to the protection of refugees. The study commences with a general introduction, followed by an analysis of the international human rights and refugee law framework relevant to protection of refugees. This framework is used to assess South Africa’s responses. Subsequently, the discussion delves into South Africa’s own national framework on social security. Using the standards identified in both the national and international frameworks, the thesis then proceeds to measure South Africa’s Covid-19 related responses regarding social security to resolve the issue of whether South Africa adhered to these standards in as far the protection of refugees’ right to social security is concerned.Thesis (LLM) -- Faculty of Law, Law, 202
The relationship between trade opennes and government size in South Africa
Get PDFThe relationship between trade openness and government size has drawn interest in the domains of public policy and economics. To add to this discourse, the current study conducts an empirical analysis using annual data covering the years 1994 to 2020, focusing on South Africa as the case study. By analysing the complex dynamics between trade openness and government size, this study aims to offer an insightful analysis of the economic landscape and shed light on the implications for government policies. An autoregressive distributed lag (ARDL) model was utilized in the study, allowing for a thorough analysis of the short- and long-run relationship between trade openness and government size. The empirical findings indicate a substantial positive relationship between trade openness and government size. Moreover, the Granger causality demonstrates that trade openness and government size in South Africa have a unidirectional causal relationship, which further solidifies this relationship, aligning with theoretical literature's compensation hypothesis. Based on the findings indicating a substantial and positive relationship between trade openness and government size, as well as the Granger causality research supporting the compensation hypothesis, certain policy implications emerge. To optimize economic outcomes in South Africa, policy-makers could focus on implementing trade liberalization policies to reduce barriers and promote free trade agreements, facilitating economic integration and access to new markets. Additionally, attention to prudent public expenditure management becomes crucial, ensuring that increased government size is accompanied by efficient allocation of resources to foster economic growth and development.Thesis (Masters) -- Faculty of Economics and Financial Sciences, 202

Towards an effective model for improving Water Sanitation and Hygiene (WASH) by local authorities in Zimbabwe: a case of Runde Rural District Council (RRDC)
No full textThis study is concerned with public service provision with reference to water, sanitation and hygiene (WASH) programming in Runde Rural District in Zimbabwe. This thesis is informed by the Stakeholder theory by Freeman and the Stewardship theory by Donaldson and Davis. The Stakeholder theory emphasises the importance of harnessing the comparative advantages of various stakeholders in rural WASH. Stewardship theorists believe that public administrators and stakeholders have no conflict of interest and that Government creates systems and processes that promote cooperation between them. An anti-positivist or interpretivist case study was conducted. In -depth interviews, observation and documentary analysis were the chief information collection instruments. Twenty (20) participants were purposively selected to participate. The thesis unearthed factors constraining improved WASH services. Local level opportunities for improving WASH programming were identified and used to build a model for effective service delivery in the community. The study recommended establishment of WASH champions at village level, to ensure provision of WASH at household level. The WASH committees at village, community and district level should be inclusive, constituted on the basis of merit and dedication. The thesis ends with the suggestion that further studies that focus on other rural districts in Zimbabwe be carried out. This thesis contributes greatly to this field of study in that it will ensure that the Runde Rural District Council will adopt a stakeholder inclusivity model to address the lack of Water Sanitation and hygiene in their area. The bottom-up approach ensures that all stakeholders have a say in Water Sanitation and Hygiene policy making processes so that the decisions made can be relevant to their challenges in accessing Water Sanitation and Hygiene.Thesis (PhD) -- Faculty of Management and Commerce, 202
The determinants of manufacturing sector growth among East African Community countries
Get PDFGiven the concern of the meagre contribution of the manufacturing sector output in total GDP within the East African Community (EAC) member states, the purpose of this study was to in-vestigate whether growth rates in the manufacturing sector output of the five East African Com-munity member states can be explained by variations in the factors of input, productivity and governance. The study benchmarks the growth frameworks of neoclassical growth and its exten-sions, as well as the institutionalist growth theory, which guided the formulation of empirical growth models. Estimation is achieved by implementing first difference generalised method of moments (D-GMM) on a linear dynamic panel model through the specific-to-general modelling technique. Among the factors motivated by the neoclassical growth paradigm and its extensions, estimates from this study indicate that human capital and the gross capital formation input factors can help in predicting variations in manufacturing sector output growth in EAC member countries. Among the productivity factors, estimates show that higher lending rates and increased openness had a significant negative effect on the growth of the manufacturing sector among EAC member states. The productivity variables of foreign direct investment, inflation, domestic credit and financial deepening showed no ability to influence manufacturing sector growth in the EAC member states. Estimates further indicate that among the governance factors, control of corrupt-ion could help boost manufacturing sector output growth among EAC member states. Results from this study show that the governance variables of voice and accountability, and of regulatory quality, had an insignificant effect on the growth of manufacturing sector output among EAC member states. So the study shows that manufacturing sector output variations in EAC member states can partially be explained by the neoclassical and endogenous growth models, with little efficacy in the institutional growth model, suggesting the incompleteness of the growth frame-works adopted in assessing the sources of growth in manufacturing sector output in EAC mem-ber states. The study results suggest that the EAC member states can boost their manufacturing sector output growth by implementing policies and programmes that create incentives for more additions to capital stocks and improving the quality of human resources while equipping people with skills, establishng financial instituitions which offer access to cheap capital, like the East African Development Bank, and adopting import substitution growth strategies which could re-duce the quantity of imports and limit outflows of foreign exchange.Thesis (PhD) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 202
Enhanced peoples housing process and income generation: a case study of the Vulindlela self-help housing programme in Kwazulu-Natal, South Africa
Get PDFThe study presented in this thesis examines the effects of the Vulindlela self-help housing programme’s governmentality on income-generating opportunities by beneficiaries; the rationale and assumptions underpinning the self-help housing programme; and evaluates whether the programme was implemented according to policy. The study also investigates the relationship between the Vulindlela self-help housing programme’s beneficiary involvement, beneficiary satisfaction, and skills development provided by the programme on income opportunities for beneficiaries. Using the empirical case study of the Vulindlela self-help housing programme in KwaZulu-Natal, South Africa, this study verifies the EPHP’s view that self-help housing programmes provide fertile ground for livelihoods, income generation and asset ownership. The study is underpinned by the interpretivist paradigm, which relies on qualitative and quantitative data, comprising primary data (individual key-informant interviews and survey data); as well as secondary qualitative data from desktop research. It utilises a Foucauldian approach, in which the rationalities and practices of the self-help housing programme, and the effects of the technologies of self, power, self-esteem, self-responsibilisation and the market, are evaluated to see how these factors have influenced income generation by beneficiaries in one of the largest self-help housing policy programmes in SA. These technologies are examined in the context of the Vulindlela programme using Foucault’s theory of governmentality. The findings confirm that the Vulindlela programme was implemented according to its policy. However, not all aspects of the policy programme were understood or may have been implemented during the programme. As such, not all participants (i.e. housing beneficiaries, government officials and cooperative directors) understood the intended outcomes nor how these policy outcomes would be realised. Despite many challenges that confronted the implementation of the Vulindlela self-help housing programme, the study concludes that the governmentality of the Vulindlela self-help housing programme had a positive impact on income opportunities for beneficiaries. The programme is one that finds itself held between two contradicting rationalities: neoliberal aspirations (provision of market and income opportunities for cooperatives that vii act as contractors), and moral aspirations (initiating empowerment of disadvantaged beneficiaries/ community development). The rationale behind the Vulindlela self-help housing programme was about providing income opportunities for beneficiaries and was heavily influenced by the neoliberal ideas of the UN-Habitat and the World Bank. Key policy recommendations, informed by implementation challenges of the Vulindlela programme, are offered for policy adjustments, as well as a conceptual framework for the design and implementation of self-help housing programmes to realise intended policy outcomes, that is income generation by housing beneficiaries and enhancement of local economic opportunities through the programme.Thesis (PhD) -- Faculty of Engineering Built Environment and Technology, School of Built Environment and Civil Engineering, 202
Rapid Synthesis of Thiol-Co-Capped CdTe/CdSe/ZnSe Multi-Core-Shell QDs and Their Encapsulation in Liposomes and Chitosan Nanoparticles; Comparative Bio-compatibility Studies Using Hela and Vero Cells
Get PDFThe common method that has been used to reduce the toxicity posed to living cells by CdTe Quantum Dots (QDs) is through the synthesis of CdTe multi-core-shells nanoparticles. In this process, the surface of CdTe QDs is usually coated by less toxic ZnS or ZnSe shells. This heterostructure compound does not only reduce the toxicity of CdTe QDs but can also be used in applications such as deep tissue imaging. The heterostructures can be in numerous forms such as CdTe/CdSe/ZnSe or CdTe/CdSe/ZnS or CdTe/CdS/ZnS multi-core-shell QDs. However, the drawbacks attributed to the fabrication of these compounds is long synthesis times (6- 24 h) in achieving the highest wavelength emission maxima. Others are the use of toxic reagents and poor reproducibility of synthesized materials. An additional problem is that the ZnSe or ZnS coating is insufficient to completely protect the highly toxic Cd metal from escaping into immediate solution. This limits their use in biochemistry and with living systems. Liposomes and biopolymers such as chitosan are known to be environmentally friendly compounds that have been used in various studies as delivery systems for QDs and model drugs for drug delivery applications. They are generally non-toxic and highly bio-compatible. In this study, the rapid synthesis of thiol-co-capped CdTe/CdSe/ZnSe multi-core-shell QDs with a maximum reaction time of 35 mins, gave reliable QDs with emission maxima at 625 nm. The multi-core-shell QDs were encapsulated in two different bio-compatible environments, namely liposome and chitosan nanoparticles (CNP) at 14 different formulations (F) for liposome and 12 different formulations for CNP. Cytotoxicity and florescence imaging studies using HeLa and Vero cells, were used to investigate the improved bio-compatibility. Various characterization techniques were used to elucidate the optical properties, morphology and physico-chemical properties of the QDs and nanocomposites. Two of the best formulations, QD-liposome vesicles (LVs)-F12 and QD-CNP-F9 (with chitosan), demonstrated high loading efficiencies of 42 ± 6 % and 59 ± 5 %, respectively. While the plain CdTe QDs showed high toxicity, some of the encapsulated materials, QD-LVs-F1 and F12, depicted no-toxicity against the cells (IC50 > 0.5 mg/ml). The QDs also retained most of their fluorescence and properties and could easily be tracked in cells and visualized around the nucleus, indicating the successful internalization of the QDs in the cytosol. These results shows that encapsulation of CdTe multi-core-shell QDs in liposomes produce better bio-compatibility compared to multi-core-shell QDs and better than CNP coating. These particles therefore show good promise in cell-labelling, drug delivery studies. Their core-shell nanoparticles have also shown good behavior in enhancing the memory of a device which is based on some recent collaborated works.Thesis (PhD) -- Faculty of Science, Chemistry, 202
The morphogenesis of higher education leadership: a social realist exploratory journey
Get PDFThe purpose of the study underpinning this thesis was to explore the tensions experienced by university leaders as they balance politics, power and the academic project whilst pursuing their ultimate concerns in the world. Universities are undergoing constant change, particularly in the present time of hypercomplexity, where the discourses of globalisation and neoliberalism condition higher education institutions and their leaders. This predisposes universities to operate as a market economy rather than as a public good. University leaders are under immense pressure as they seek to reposition themselves and exercise their agency in steering their institutions in a landscape fraught with complexity and contestation about the very nature of the modern university. The study was located in a traditional university in South Africa, which added another layer of complexity given the history of Apartheid and, the use of education as a means of discriminating against the black majority population, and the subsequent attempts by the government to transform the system following the first democratic election of 1994. Bhaskar’s (1989) critical realism and Archer’s (1998, 2000) social realism were used to frame the study theoretically. Bhaskar argues for the understanding of the world as an ‘open system’ in which experiences and events emerge from the tendential interplay of mechanisms at a layer of reality not directly accessible to empirical observation. Archer’s (2000) social realism draws on critical realism to provide a set of tools that allows an exploration of the social world in more detail. This study draws on the tools of analytical dualism, or the temporary separation of structure, culture and agency for analytical purposes, and Archer’s (1998) morphogenetic framework, which allows for the exploration of change, or non-change, over time. The overarching goal of the study was to explore how leaders at one South African university were enabled and constrained as they exercised their agency in the pursuit of projects they had identified to address their ultimate concerns about the world more generally and higher education in particular. However, the study also sought to explore the construct of leadership itself in a specific context by using Archer’s (2007, 2012) theoretical work on reflexivity. The study drew on in-depth interviews with senior leaders at the institution, including two vice-chancellors. The interviews were subjected to analysis, and the inferential tools of abduction and retroduction were used to identify the interplay of mechanisms located at the level of the Real, the deepest layer of reality posited by Bhaskar (1978), which led to the events and experiences reported by leaders. A literature review was used to identify additional theories that were used in the processes of abduction and retroduction. The study revealed that change, or rather non-change, is often concealed in cultural rhetoric veiled in leadership practices in acts assimilating past ideology and codified rules and practices with new codified rules and practices. Leaders often draw on powerful relational networks as they reflexively exercise their agency, and these networks can also work to constrain change.Thesis (PhD) -- Faculty of Education, Education 202
Formulating an operational efficient strategy for the national health laboratory services in the Eastern Cape
No full textThis treatise presents the formulation of an operational efficient strategy for the National Health Laboratory Services (NHLS) in the Eastern Cape. Operational inefficiency in the NHLS has the potential to delay laboratory results delivery for necessary health intervention, which may have a negative impact on individuals’ health or lead to death. The aim of the study is to highlight inadequacies that may cause poor service delivery and formulate an operational plan for the NHLS in the Eastern Cape. Strategic efficiency is derived from the resource-based and agent theories. Even though there is a difference between service and manufacturing industries, the operational strategic framework can be used in both. A strategic framework is implemented by assessing market requirements and using the top-down or bottom-up approach. To monitor and regulate these strategies, one can utilise, among others, scorecards, corporate social responsibility and risk management. This is a qualitative research study using semi-structured interviews to gather information from 11 participants. The study targeted managers in the NHLS Eastern Cape region, with a non-probability method, as the large number of managers in the entire region made it impossible to do a random study. Furthermore, the data were analysed by the thematic analysis method. The literature review identified six factors that influence public sector efficiency, namely, compliance issues, ethics, financial expense management, resource optimisation, accountability and service delivery. The primary study revealed several inadequacies in the NHLS Eastern Cape, namely, inefficient human resources practices, underutilising technology, ambiguous policies, delayed turnaround time, lack of financial training for management and lack of support from cross-functional departments. In addition, the results of the study warrant the following recommendations: Proper orientation of staff, with modules pertaining not only to their duties and reporting structure but also to the policies of the organisations and conduct; SWOT analyses and surveys could also be used to assess internal staff and external factors that may hinder efficiency; the installation of solar panels for laboratories, starting with the vulnerable labs in remote areas, wireless internet technology, mobile applications and software. The region also needs to practice good corporate governance, update its policies regularly and budget for all operations, including quasi fiscal activities. Lastly, support departments need to comply with an ISO certification.Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 202
The contribution of women to household food security in Makholokeong Village and Diyatalawa village, Free State Province
Get PDFThe study investigated the contribution of women to household food security in Makholokoeng village and Diyatalawa village, Free State Province. Women’s contribution to household food security is poorly documented and misunderstood. Most often women’s contribution is considered as part of the duties of women as a wife and mother than as an occupation to be vaunted for both the household and national economy. Women play crucial roles in household food security as food producers, processors, and food providers for their families. Despite these crucial roles women remain unrecognised as main contributors of household food security. The study was guided by pragmatic research philosophy that used Participatory Rural Appraisal tool amongst other data collection tools to answer the objectives of the study. The study findings show that there is a clear-cut of the agricultural roles men and women perform in agriculture but the involvement of women in decision-making varies with crops and the type of household. The contribution of women to household food security is evident. However, women continue to face challenges which are limiting the role of women in household food security. The study recommends that further studies should be conducted to investigate gender roles in agriculture; and the effectiveness of gender equality policy implementation in agricultural initiatives.Thesis (MA) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 202
