- Description: Many countries in the world consider the tourism and hospitality industry as the leading employer with huge impact on economic growth. It has significantly contributed to their national Gross Domestic Product (GDP). Several studies conducted world over affirm that tourism contributes above the global average of ten percent. In Zimbabwe, the estimated percentage has also been as high as 10percent. The Tourism and Hospitality Management (THM) program aims to equip youth with critical industry-specific skills and mitigate unemployment. Despite this, literature has revealed that certain graduates struggle to secure industry positions due to a discrepancy between acquired skills and employer expectations. Consequently, some graduates accept menial roles outside the tourism sector, while the industry itself resorts to employing unqualified personnel. The reason lies in ineffective curriculum implementation approaches characterized by a lack of appropriate pedagogical methods. Identifying and implementing effective strategies ensures that graduates possess the requisite skills and competencies demanded by the industry, making their employability much easier. This study used a qualitative approach because of its exploratory, descriptive, and contextual nature. The interpretive paradigm provided participants’ views, opinions, and thoughts on the THM curriculum implementation. The multiple case study research design allowed ample freedom to dig deeper into rich empirical data by examining contemporary trends in implementing the ND3 in THM curriculum at two polytechnic colleges. Non-probability convenience sampling was used to select the two polytechnic colleges. Purposive sampling was used to select twelve (12) students, six (6) lecturers, and two (2) ITTD inspectors. Lecturers and inspectors were interviewed. Data from students was obtained through Focus group discussions. Curriculum documents were reviewed to provide true realities of the THM curriculum implementation. Content analysis was used to analyse data. Rogan and Grayson (2003) curriculum implementation theoretical framework guided the study. The study revealed that lecturers were dissatisfied due to inappropriate pedagogical strategies. A new model to bridge the theory/ practice gap in teaching was developed. The study recommended the adoption of a new and modern teaching model and fix the recruitment process by employing qualified lecturers to teach ND3 in THM students. , Thesis (PhD) -- Faculty of Education, 2024

- Description: The study examines how pre-1994 magisterial districts jurisdictions denied access to justice to many South Africans, and ongoing efforts to reverse this injustice. Delayed rationalisation of the judiciary and reform of the courts territorial jurisdiction during the apartheid era exacerbated the problem. The courts administered justice along spatial racial divide, and given the location of the courts, many black communities had to commute long distances to access justice and at a great cost and inconvenience. The Constitution of South Africa of 1996 provides not only for the right to equality before the law and equal protection and benefit of the law but also the right to access the courts and seek recourse. In a period spanning eight years from December 2014, new magisterial districts were proclaimed in all the nine provinces of South Africa. Despite this milestone and the imperative of the 1996 Constitution, the rationalisation process is still in its infancy: old legislation and judicial structures remain intact; divisions of the High Court continue to exercise jurisdictions determined for the pre-1994 constitutional dispensation. The status quo continues to perpetuate the denial of access to justice to communities especially those living in areas that hitherto formed part of the former homelands and self-governing ‘states’. The study was conducted through a desktop survey of primary and secondary material relevant to the rationalisation process. It drew lessons from the re-demarcation of municipal boundaries which, like magisterial districts, were based on racial laws and policies of the past. It also contrasted rationalisation principles in comparable jurisdictions. The findings provide a useful contribution to the ongoing effort to effect rationalisation of the court system. They also contribute to knowledge and enriches our understanding of the relationship that underpins the administration of justice in a dispensation driven by democratic, human rights and constitutional ethos. , Thesis (PhD (LLD)) -- Faculty of Law, 2024

- Description: Ambidexterity is the capacity of an organisation to develop both exploration and exploitation capabilities simultaneously. These require different types of responses. This thesis investigates the role of ambidexterity in small and medium enterprises (SMEs). Ambidexterity is associated with network capability and value co-creation. In addition, SMEs can benefit from ambidexterity by reducing the risk of failure and promoting growth. The results suggest that ambidexterity in conjunction with networking partnerships and co-creation are key capabilities for small businesses. Secondly, they reveal that SMEs can develop ambidexterity by engaging in both formal and informal learning from their networking partnerships. This is important for policy makers because it suggests that government support for SMEs should focus on developing both formal and informal learning opportunities. Managers of SMEs should also focus on developing both formal and informal learning opportunities. It is an important capability for the success of these businesses. Networks can also be used as a learning mechanism by SMEs. Furthermore, the research also suggests that the use of digital technology networks can be beneficial for the development of ambidexterity. This means that SMEs should consider investing in digital technology networks to enhance their ambidexterity capabilities. Additional research is needed to determine the specific benefits that digital technology networks provide to SMEs. However, the findings suggest that digital technology networks can help to improve the development of ambidexterity. Although networks and co-creation may be necessary for SMEs, they should caution that openness to change can also be risky. It is essential to manage the risks associated with susceptibility to change. SMEs should consider investing in digital technology networks to help them manage these risk. , Thesis (PhD) -- Faculty of Management and Commerce, 2023

- Description: Many Sub-Saharan African (SSA) countries experience low economic growth rate levels which is worrisome given the demographic window of opportunities in the region. The governments of SSA countries have been putting emphasis on increasing investments in human capital development as it is vital in unlocking potential economic growth through enhancing regional productivity. With this in mind, this study examined the effect of human capital investment on economic growth through productivity in 12 selected SSA countries during the period 2000 to 2017. The selection of these countries and the study period were based on the data availability as well as differences in income growth. The sample represents all the countries in the income growth groups which are low income, lower middle income and upper middle income. In order to examine the overall effect of human capital investment on economic growth the study utilizes two models which are: 1. Human capital investment and productivity in selected SSA countries. 2. Human capital investment and economic growth in selected SSA countries. Model 1 objective of the study was to investigate the effect of human capital investment on productivity in the selected SSA countries. Productivity proxied by labour productivity measured by real output per person employed was the dependent regressed against a host of independent variables which includes human capital investment, foreign direct investment (FDI), total factor productivity (TFP) and labour quantity growth (LQ).The human capital investment components used in the model included: fiscal expenditure on primary education (PEI), secondary education(SEI), tertiary education (TEI) all as a percentage of government expenditure on education; public health(PHI) as a percentage of GDP and domestic private health (DPHI) as a percentage of current health expenditure. Several estimation techniques which include the Pooled Mean Group (PMG), Panel Fully Modified Ordinary Least Square (PFMOLS) and Panel Dynamic Ordinary Least Square (PDOLS) were employed to analyse the relationship between the variables of interest. The empirical findings indicated that all human capital investment components contribute positively to labour productivity except tertiary education investment which had a negative effect. Moreover, the empirical findings also revealed that foreign direct investment and total factor productivity had positive effects on labour productivity while labour quantity growth had a negative effect. Model 2 objective examined the effect of productivity enhanced human capital on economic growth in the sample of countries. It also incorporated the direct channel of the effect of human capital on economic growth in the stated countries. Economic growth (EG) proxied by real GDP growth as the dependent variable and, on the other hand, explanatory variables being productivity enhanced human capital investment (PEHC), human capital (HC), gross fixed capital formation (GFCF), population growth (POP), institutional quality proxied by government effectiveness (GE) and political stability (PS). The same estimation techniques were also employed so as to obtain robust results. The empirical findings revealed that both productivity enhanced human capital investment and human capital contributes positively to economic growth in the selected SSA countries. In addition, the empirical results also proved that gross fixed capital formation, government effectiveness and political stability have positive effects on economic growth whilst population growth has a negative effect. Overall, the results of the study evidenced the existence of a transfer mechanism from human capital investment to economic growth through productivity in the selected SSA countries. The empirical results imply that increasing investment on human capital is of importance in trying to enhance productivity and through this economic growth in the SSA region. The study concludes that there is a potential on enhancing economic growth in the long run in the SSA region if countries invest more on human capital. Therefore, the study recommends that SSA countries must devote more budget to human capital so that free basic education can be offered in both primary and secondary as well as free health care services. With this, the objectives of quality education and health, sustainable and inclusive growth targets of the African Union (AU) Agenda 2063 as well as United Nations (UN) Sustainable Development Goals (SDGs) can be achieved. , Thesis (PhD) -- Faculty of Management and Commerce, 2023

- Description: The study investigated the impact of financial integration on financial development and economic growth in the Southern African Development Community using annual data for the period 2000 to 2018. Literature shows that there is no universally accepted measure of financial integration hence the study utilized the Lane and Milesi-Ferretti measure, foreign direct investment as a percentage of GDP and Chinn-Ito (KAOPEN) index in achieving the objectives of the study. One of the main objectives of the study was to examine the impact of financial integration on financial development in the SADC community. The study utilized first difference GMM to achieve this objective and the results showed that Lane and Milesi-Ferretti measure and foreign direct investment as a percentage of GDP significantly affect financial development whilst Chinn-Ito (KAOPEN) index displayed an insignificant effect. The next step was to investigate the impact of financial integration on economic growth in the SADC region. To accomplish this objective, the study investigated both the direct channel as well as the possibility of financial integration indirectly influencing economic growth through financial development, trade openness, and institutional quality. The Three Stage Least Squares (3SLS) technique was utilized on a system of five simultaneous equations in examining the effect of financial integration on economic growth. The results revealed that financial integration affects economic growth both directly and indirectly. Regarding the indirect channels, only the financial development and institutional quality channel proved to be significant. To ensure the robustness of the results the study checked if the impact of financial integration was sensitive to the measure of financial integration and financial development used. The study employed KAOPEN to proxy financial integration while broad money supply (% of GDP) measured financial development. Robustness results confirmed that financial integration affects economic growth both directly and indirectly. This time, the trade openness channel was significant at 10% which shows the benefits through this channel are significant. This shows that the results of the trade openness channel are inconclusive. When the Lane and Milesi-Ferretti measure of financial integration was employed the impact of the trade openness channel was insignificant whilst a significant impact was found based on KAOPEN. The inconclusive findings for the trade openness channel may indicate the impact of financial integration on economic growth depends on the proxy of financial integration utilized. In addition, the study also gathered some interesting results where financial development, institutional quality, trade openness, and government size (government spending) are significant drivers of financial integration. The study makes some fundamental contributions to literature on financial integration, financial development, and economic growth. Initially, the study provides empirical evidence on the nature of the impact of financial integration on financial development in the SADC. In particular, this study contributes to the body of knowledge by showing that the impact of financial integration on financial development is linear. Secondly, this study makes an original contribution to the literature on the channels through which financial integration affect economic growth in the SADC, providing a more subtlety understanding of the mechanisms at play. Finally, the study provides important policy implications for policymakers and financial regulators in the SADC who seek to promote economic growth through financial integration. The findings of the study imply that deeper financial integration is crucial in the SADC region as it can potentially increase the rate of economic growth in the region. Not only economic growth will be boosted but also the institutional quality and the development of the financial sector of the countries in the region. Based on these findings, the study recommends that the governments of the member countries in the region continue to come up with policies that boost regional and international financial integration. The study suggests that to ensure that they continuously reap positive benefits from financial integration, member countries of the SADC should appoint a board that deals with implementation and accountability. This board must be responsible for ensuring that member countries implement the formulated policies and should also hold member countries accountable in case of failure to implement the formulated policies. Since the region is pursuing financial integration, the region must come up with policies that prioritize domestic developments in the form of financial development, improving domestic institutional quality and reducing trade restrictions in advance in order to ensure that preconditions for financial integration are met. Developing these will attract different forms of financial flows or increase financial openness which will ultimately boost economic growth. , Thesis (PhD) -- Faculty of Management and Commerce, 2023

- Description: The housing market contributes significantly to economic growth. On this background, the study examined South Africa’s housing market dynamics, particularly determinants of demand, supply, and formal housing prices. Furthermore, the study looked at the impact of housing prices on economic growth from 1994:Q1 to 2019:Q2. The study period is important as it covers the new political dispensation in South Africa where the country entered a new democracy in 1994. The first three objectives of the study were to identify the determinants of housing demand, supply, and prices. The theory of demand and supply provided the theoretical framework for these models. Estimation of the housing demand, supply and price models was done by the employing Seemingly Unrelated Regression (SUR) technique. The Three Stage Least Squares (3SLS) model was estimated for robustness. Findings from SUR and 3SLS confirmed that Housing Demand (HD) is negatively and significantly influenced by residential Building Costs per Square Meter (BCSM), Housing Supply (HS) and Financial Costs (FC); and positively influenced by House Prices (HP). In addition, HS is negatively affected by BCSM, HD, Production Costs (PC) and Urban Population (UP); and positively influenced by HP and Residential Construction Confidence (RC). Lastly, HP are negatively affected by Prime Overdraft Rate (POR) and RC; and positively influenced by BCSM, HS, HD, Coincident Business Cycle Indicator (CBC) and residential Valuation (VAL). The fourth objective was to examine the impact of house prices on economic growth. An economic model was specified with Gross Domestic Product (GDP) as its dependent variable. The new growth theory provided the theoretical framework for this model. The Johansen co-integration technique confirmed a long run-term relationship between economic growth and house prices. The Vector Error Correction Model (VECM) was estimated to analyze the long and short run relationship among the variables. Empirical results confirmed that house prices have a positive impact on economic growth. Results further confirmed that CBC and Unemployment Rate (UR) are also positively related to GDP. POR and Leading Business Cycle indicator (LEBC) are negatively related to GDP. Granger Causality test was performed to analyze the causality between house prices and economic growth. The results indicated that there is a long run unidirectional causality from house prices to economic growth. With these results, the study recommends policy formation emanating from continuous research by establishing a human settlement agency or task team. The team can establish procedures for data collection and maintain a database for all kinds of housing market data. Their mandate includes research on commissioning of new towns and/or cities to boost housing supply. The government should avail more land and relax restrictive regulations and minimize red tape to ensure that houses are supplied to meet the growing demand as well as to stabilize prices. Policies to promote confidence and stabilize building costs are needed. These variables indicated significant influence on housing dynamics. It is also recommended to incentivize households to participate on the mortgage market. This assist both households through the wealth effect which positively influence increase in economic activity in South Africa. , Thesis (DCom) -- Faculty of Management and Commerce, 2023

- Description: Developing countries are increasingly recognising the need for promoting women entrepreneurship. Within Africa, women’s contribution tends to be ignored. Thus, gender discrimination, the lack of finance, limited education, limited technical skills, role conflicts, and culture are among the most cited barriers for women entrepreneurship. Recent literature challenges the notion that all aforementioned factors are barriers to entrepreneurial action. To contribute to knowledge, this study sensitises the culture element. Accordingly, there is a growing body of knowledge that is viewing culture as an enabler (and not a barrier) of women entrepreneurship. Two factors are at the core of this argument: (1) culture, as it is understood, in the contemporary literature is not appropriately conceptualised from an African perspective. (2) The definition of entrepreneurship as it relates to the developing countries is restrictive. These definitions ignore various economic activities undertaken mostly by women, which if carefully considered are indeed entrepreneurship. Therefore, it was appropriate for this thesis to explore the issues of both culture and entrepreneurship within the existing body of literature with the intention of gaining a knowledge of the dynamics of women's entrepreneurship in Africa. The scant research that has been done on the entrepreneurial dynamics of women and, in particular, how culture influences the latter, was recognized as a lacuna in the existing body of literature. Consequently, this study considered cultural determinants of entrepreneurship as well as the transmission of entrepreneurship across generations. The thesis was undertaken using a qualitative methodology. Using snowballing sampling technique, female entrepreneurs from 3 provinces (i.e., Gauteng, Limpopo, and Eastern Cape) in South Africa participated in the study. Data were gathered through in-depth interviews. The transcribed interviews were analyzed using thematic analysis. Findings revealed, among others, that there is a misconception on what constitutes “true African culture.” Thus, results suggest that the conceptualisation of culture in the African context, contrasts the conceptualisation in previous (non-African) literature. Furthermore, some elements of culture are indeed barriers. Interestingly, personal factors such as characteristics of women entrepreneurs and entrepreneurial intentions have also contributed to the barriers to women entrepreneurship. Finally, the study proposes a framework for leveraging culture to be an entrepreneurial enabler for women entrepreneurship. , Thesis (PhD) -- Faculty of Management and Commerce, 2023

- Description: The aim of progressing learners is to allow them to move with their age cohort, thereby boosting their motivation levels. It is believed that this would encourage these learners to study hard and produce good academic results. The Grade Progression Policy also assumes that the dropout rate caused by learners’ academic underperformance would be reduced. Despite the existence of the Grade Progression Policy, it seems that there is still high failure and dropout rates among progressed Grade 12 learners in the Eastern Cape Province. This qualitative case study was premised on the interpretivist paradigm and explored the implementation of the Grade Progression Policy and its implications on progressed Grade 12 learners’ identities. Twelve teachers (four principals, four Departmental Heads, four Post Level One teachers), and four learners were purposively selected in four secondary schools in the Amathole East Education District. Data was collected through semi-structured interviews and documentary analysis. The data was analysed by means of thematic approach. The data showed that the implementation of Grade Progression Policy brought about learner-teacher adversarial relations. Findings also showed that teachers had a negative attitude to the Grade Progression Policy and were unwilling to adapt to change. They had low morale and blamed the Department of Education for not giving them support. With regards to the implications of grade progression on Grade 12 learners’ identities, it emerged from the data that these learners were negatively affected by the implementation of this policy as their self-esteem was reportedly low. They felt stigmatized and regarded themselves as learners who could not achieve academically. Although most of the selected learners reported that it enhanced their motivation levels, it also transpired from the data that progressed Grade 12 learners were not achieving academically and were inadequately given support by the teachers. The study concluded therefore that the policy did not sufficiently address the intention of the DoE in terms of improving learners’ academic performance and enhancement of learners’ psychosocial identities. , Thesis (PhD) -- Faculty of Education, 2023

- Description: Flukes and snail-borne diseases present significant challenges to livestock production, particularly impacting the dairy industry in the Eastern Cape Province, South Africa. Despite the challenges faced by the dairy sector, the level of knowledge and awareness among dairy farm personnel regarding the prevalence of bovine fasciolosis is unknown in Eastern Cape Province. Additionally, the genomic sequence of Fasciola spp. in dairy cattle slaughtered under abattoir conditions remains undisclosed. The primary objective of the titled study is to evaluate the knowledge, awareness, and molecular epidemiology of fasciolosis in dairy cattle slaughtered in three commercial abattoirs in the Eastern Cape province of South Africa. A structured questionnaire was prepared and randomly administered to 152 dairy farm personnel to investigate the knowledge and awareness of the aetiology, risk factors, and clinical signs of bovine fasciolosis among dairy farm personnel in the Eastern Cape Province, South Africa. A higher proportion of respondents from coastal regions were knowledgeable about the aetiology P equals 0.001 and the intermediate host P equals 0.000 of fasciolosis than those from the inland farms. A higher proportion of dairy farm personnel were not knowledgeable about the clinical signs of fasciolosis P equals 0.000 and the zoonotic potential P equals 0.001 of the disease. All farm personnel knew that season P 0.001 is a risk factor associated with snail-borne disease and occur throughout the year. However, the majority 63.2 percent of farm personnel agreed that fasciolosis was more prevalent in the summer followed by spring 27.6 percent, autumn 4.7 percent and winter 4.7 percent. Experiment 2 examined the body condition scores, fluke intensity, liver pathology, and carcass quality of various dairy cattle genotypes affected by Fasciola spp. infection, within three high-capacity abattoirs located in the Eastern Cape Province, South Africa. Milder infections were significantly noted to occur at a higher rate P 0.05 in Cross-bred cattle 46.9 percent followed by Holstein Friesian 39.5 percent and Jersey 30.9 percent cattle. Conversely, moderate infections were more prevalent P 0.05 among Jersey cattle 28.0 percent followed by Holstein Friesian 15.4 percent and Cross bred 1.9 percent cattle. Severe infections were more frequent P 0.05 in Holstein-Friesian 45.1 percent, followed by Jersey 41.9 percent and then Cross-bred 31.7 percent cattle. Heavy infections were observed in cattle with poor body condition scores in CA3. Mild infections were observed more in cattle with moderate body condition scores in CA3 and CA1 and less in CA2. Chapter 5 compared the detection rate of Fasciola infections using four different methods real-time quantitative polymerase chain reaction qPCR faecal sedimentation, antibody enzyme linked immunosorbent assay Ab ELISA and post-mortem liver examination among naturally infected cattle slaughtered at the abattoirs in the Eastern Cape Province, South Africa. A total of 145 slaughter cattle were screened for Fasciola infestation by liver examination, and corresponding samples from individual animals were analysed in the laboratory using Ab ELISA faecal sedimentation, and qPCR. The detection rate by liver inspection gold standard was significantly P 0.0001 higher than that by sedimentation and Ab ELISA but not significantly P 0.05 different from that by qPCR P equals 0.198. Post-mortem liver examination 94.5 percent and qPCR 90.4 percent had higher detection rate compared to Ab ELISA 22.6 percent and sedimentation 3.53 percent, respectively. The agreement between Ab ELISA and sedimentation was poor to slight kappa equals to minus 0.09 and with qPCR it was 0.008. The fourth experiment investigated genomic sequence of Fasciola spp. from faecal sample of slaughtered dairy cattle in Eastern Cape Province South Africa. Sequential and phylogenetic analyses were conducted to detect the presence of Fasciola spp. from the faecal samples obtained at the high throughput abattoirs. Fasciola hepatica and F. gigantica ITS 2 sequences were obtained by amplifying the 364 bp and 300 bp genes, respectively using species specific conventional PCR assays followed by cloning and sequencing. The phylogenetic tree revealed the presence of Fasciola hepatica as the only aetiological agent infecting dairy cattle in the Eastern Cape Province South Africa. The study concluded that dairy farm personnel lacks knowledge about zoonotic potentials, aetiological agents of fasciolosis high fluke intensity and its impact on carcasses sensitivity and suitability of detection methods. The study observed Fasciola hepatica as the only trematode spp. present in Eastern Cape Province South Africa. , Thesis (PhD) -- Faculty of Science and Agriculture, 2023

- Description: This study investigated the effectiveness of the communication strategies used to implement the migration of telephone services from post-paid to prepaid billing at TelOne Zimbabwe. This study adopted the Freeman‟s stakeholder theory and the Lewin‟s change model to analyse the factors that influenced the effectiveness of the communication strategies used by TelOne before, during and after the change implementation as a way to communicate the initiative with its stakeholders. A qualitative approach was utilised and the key research methods used included document analysis, participant observation, as well as 21 face-to-face and 79 telephonic semi-structured interviews conducted with respondents from among TelOne managers, employees and the customers. The documents and respondents were purposively sampled based on the researcher‟s knowledge of their relevance in the study. The findings revealed several factors that mired effective change communication strategies such as company image, stakeholder recognition and communication centralisation. To curb these communication challenges, the study proposes Thrive organisational communication change model TOCC that encourages organisations to communicate the initiative to its relevant internal and external stakeholders considering their views and addressing factors that might hinder effective communication as a strategy to enhance successful change management. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2023

- Description: South Africa continues to experience unacceptably high Human Immunodeficiency Virus HIV incidence rates among youths aged 15 to 24 years. Remarkably, this is despite the numerous youth HIV prevention programmes that have been implemented in the country. Unfortunately, the programmes have not significantly curbed the spread of HIV due to the partial and fragmented nature of their implementation. The programmes are also observed to be weak in addressing complex economic factors recognised as important structural drivers for vulnerabilities that put youths at risk of HIV infection. To address this challenge, there is increased adoption and implementation of the Combination Social Protection introduced in this research as the CSP by Non-Governmental Organisations NGOs. The CSP is a youth empowerment programming strategy whose critical foundations are entrenched in combining economic strengthening interventions and HIV prevention education. CSP could provide youths with a set of indispensable life skills that enhance their competencies and agency to make informed and effective decisions regarding their health and economic lives. Despite its growing traction, little is known regarding links between the CSP and its abilities to improve HIV prevention outcomes for youths. Given the paucity of research, this study aimed to explore the experiences of youths participating in the CSP and HIV prevention programme, with a particular focus on the resource-constrained settings of Gauteng Province in South Africa. This study employed a collective case study design, within the qualitative approach, and was exploratory. In-depth individual interviews were conducted with 30 youths from six established NGOs in the City of Johannesburg (CoJ). Qualitative thematic analysis was employed as a data analysis strategy. Focus groups were separately with six practitioners from the same six NGOs, and five officials from the Department of Social Development (DSD). Both phases of data collection were guided by interview themes, which were aligned with the objectives of the study. The findings of the study point to the fact that the CSP’s innovative and holistic approach offered numerous transformative and empowering benefits to youths. It equipped them with basic informational resources, capabilities, and social assets to safeguard their health and aid their economic advancement. The programme’s mixedgender sessions provided space, freedom, and support for youths to engage on issues of gender, differential access to health and socio-economic opportunities. Another major finding of the study was that improvement of economic aptitude (brought about by financial literacy education), employability, and entrepreneurship training stirred a sense of agency and purposefulness among youths, which in turn, prompted them to be more focused on achieving long-term objectives instead of indulging in risky sexual practices. Conversely, findings revealed that the programme had limited opportunities and did not create an adequate supportive environment for youths to develop successful entrepreneurial or income-generating projects. There was also no structure to assist youths to access apprenticeship and employment markets. The study specifically recognised that the programme’s efforts to develop youths’ entrepreneurship and employability capabilities were curtailed by a lack of mentorshipnand access to financial capital for start-up costs. With these findings in mind, recommendations are made for the creation of an enabling environment by purposefully engaging youths, establishing collaborative relations with communities, and building networks with businesses and financial institutions that can help youths with capital, mentorship, and linkages to internship and wage employment. Such collaborations could be fundamental in unravelling the impact of the programme on building livelihoods and reducing HIV among youths. Hence, this study proposes a model with strategies to support the successful implementation of economic strengthening interventions for youths. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2023

- Description: The essence of this thesis was to study the effectiveness of integrating digital media technologies within the pedagogical approaches adopted and implemented in private and public high schools in a comparative manner. The study looked closely at private and public high schools of the Eastern Cape Province, to study the gaps of accessibility to technology by schools. The study identified the Eastern Cape Province as having a problem of poor performance in matric results at the end of each year as compared to other South African provinces. In order to select the relevant sample for the study, the researcher has utilized two secondary schools private and public in Makhanda Grahamstown and one public secondary school in Alice. The pragmatic paradigm was used to inform the study and used the mixed methods approach to data collection. The researcher distributed closed ended questionnaires to the learners in the three selected secondary schools and semi-structured interviews for the principals of the schools. The key findings reveal that the digital media tools are used for the teaching and learning purposes as well as communication to the schools’ stakeholders. The findings also revealed that various online platforms are utilized for teaching and sharing of information. For example, D6 and Ibambisa School Communicator app, WhatsApp groups for learners, Facebook, Instagram and School website for potential stakeholders. Hence, the results of this study should contribute to the field of ICTs and education in the country to solve the problems facing the teaching and learning systems of private and public schools of the Eastern Cape. Most schools (especially the public) do not have access to digital media tools in their classrooms. Thus, they still depend heavily on the textbooks, which may be outdated or not enough for all learners. In response to the issues faced by the Eastern Cape secondary schools and the findings, the researcher has suggested a model named the Digital Media and Pedagogy Integration DMPI Model of Communication. This model will contribute to the body of knowledge by providing advice to the Department of Basic Education on how teachers and learners can utilize digital media tools effectively. Also, the study has recommended that there is a need for provision of computer literacy training for teachers in secondary schools in this digital age. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2023

- Description: This study investigates the role of Forte FM, Mdantsane FM and Rhodes Music Community Radios in disseminating the different kinds of messages on the nexus between the impacts of climate change and food security in the Eastern Cape Province, South Africa. Therefore, the study aims to investigate how these community radio stations play their informative, educative and entertainment roles regarding climate change and food security awareness programmes to their listeners. The study employed the qualitative research approach and convenience, and non-probability samplings techniques were subsequently used to select samples for this study. In-depth interviews were conducted individually for Forte FM, Mdantsane FM and Rhodes Music community radio programme managers respectively, who serve as the key informants. One focus group discussion each was held with residents of Golf Course, Mdantsane and Grahamstown areas where these radio stations broadcast from, with eight participants in each focus group. The total number of participants for the focus group discussions was 24 participants. The collected data were coded into themes using NVivo 12 software to generate the theme nodes and case nodes as key findings, analysis and then interpreted. The findings of this study confirmed that these three community radio stations do contribute to climate change communication through their programmes that focus on climate change and food security related issues. Another vital finding from the study showed that listeners do benefit immensely from these climate change and food security related programmes of the under-study community radio stations. Hence, listeners physical, social, and cognitive well-being of their climatic environment have been greatly impacted. In the same vein, the findings of this study further revealed that the rural communities who are mostly affected by the impacts of climate change on food security have been well informed and enlightened on the suitable ways to enhance a sustainable food security and climate adaptation system through Forte FM, Mdantsane FM, and Rhodes Music community radio stations. Significantly, this study has been able to come up with two suggested models and the conceptual frameworks, which are the Local Action Adaptive Communication (LAAC) Model and the Indigenous Behavioral Change Conceptual (IBCC) Model. These models are focused on increasing listeners interests, adaptation, and behavioral change on climate change issues. The models are also aimed at ensuring better climate change and food security communication Author. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2023

- Description: Generally, rural areas continue to experience high poverty levels and low incomes, which seem to be occasioned by high unemployment rates, limited educational attainments, and devastating floods and droughts. This situation is further exacerbated by increase in crime rates, making livelihoods even more difficult. To mitigate such adverse situations, rural households employ diverse strategies, including maintaining community gardens, one-home-one-garden schemes, as well as livestock and poultry production. The most prevalent livelihood strategy in South Africa or KwaZulu-Natal is broiler production, since it needs less space and a short production cycle compared to other livestock or crop enterprises. At the same time, income is generated over a short period. Besides, the government of KwaZulu Natal has actively intervened in the sector as part of its broader poverty reduction strategy and farmer support programmes. In KwaZulu-Natal Province, the provincial government has been supporting broiler producers for many years. While substantial research work has been done in the province on livelihood strategies, including livestock production on a province-wide basis, there is no information about how successful the broiler production funded by the government has being. Broader concerns about production problems have not been assuaged based on systematic studies and evidence. It is this wise that this study was initiated. The objective is to assess the economic viability of government-funded small-scale broiler projects in the KwaZulu-Natal Province of South Africa and determine the implications for poverty reduction and food security. Data were collected from the government-funded small-scale broiler producers that are residing in Northern KwaZulu-Natal districts uThungulu, Zululand and uMkhanyakude. A total of 75 small-scale broiler projects 25 broiler projects in each district were selected by probability sampling procedure for the interviews. Questionnaires that combined both close-ended and open-ended questions were used to collect primary data, which include production and marketing, as well as the factors that influence the profitability of the small-scale broiler projects. After collection, data were captured and encoded on spreadsheets in Microsoft Excel and exported to Statistical Package for the Social Science (SPSS) software version 26 and STATA for analyses. Descriptive statistics applied include frequencies and means. In addition, a gross margin (GM) and gross profit margin (GPM) analysis were employed to assess the profitability of government-funded small-scale broiler projects. Both profitability and gross margin analyses were used as proxies for farmers’ motivation and incentives to participate in broiler production. Further analyses were conducted to determine the model that best explains the underlying relationships. Initially, the Multiple Linear Regression Model was applied to determine the factors influencing the profitability of government-funded small-scale broiler projects. The indication was that while positive profits were revealed, the system seemed to fall short of its potential. In light of that, it was decided to fit another model to estimate the technical efficiency of the system and gain an understanding of the causes of any inefficiency that might exist in the production system. In that regard, the one-step Stochastic Frontier Model was employed to show that the technical efficiency of broiler production systems in the project area was positively and significantly influenced by flock size, the quantity of feeds and labour costs, while medication played no role possibly because of weak extension coverage. An inefficiency model fitted as part of the one-step model suggested that age, gender and educational level were significant influencers of technical inefficiency, with the possibility that the older the farmers, the more technically inefficient the system possibly because of the strenuousness of commercial poultry production. In addition, it was found that the more educated the farmer, the less inefficient the farm, which conversely means that the system becomes more efficient as the farmer receives more education. The negative coefficient of the gender variable also implies that for farms managed by female farmers, the system was less inefficient, which is more technically efficient, and this can be explained by women’s propensity to be more gentle, caring and sensitive in managing the chickens than their male counterparts. Heteroskedasticity tests and corrections were conducted in the one-step estimation technique to show that variations in the inefficiency term (μ) and the stochastic error term were explained by age and educational level for the most part. Clearly, improvements in the broiler industry in KwaZulu-Natal will depend to a large extent on the knowledge and experience of the farmers and substantial enlargement of the flock size of adequately fed birds. Attention to these elements is expected to have important practical implications for sustainable broiler poultry development and food security in the project area, as well as locations possessing identical features and characteristics. , Thesis (MSci) -- Faculty of Science and Agriculture, 2023

- Description: The adoption of international instruments namely, the Model Law on Electronic Commerce, the Model Law on Electronic Signatures and the United Nations Convention on the use of Electronic Communications in International Contracts was mainly necessitated by the need to remove unnecessary obstacles to the development of e-commerce. However, many years later, countries in the Southern African Development Community (SADC) are grappling with the effective regulation of e-commerce. Globally, e-commerce has been embraced as an instrument for boosting economic growth to achieve various developmental goals including employment creation and poverty alleviation, among others. Given its significance and transnational nature, a comprehensive harmonised regulatory framework that enhances regulatory certainty remains a sine qua non to the development of e-commerce. This study examines the SADC’s regulatory approach to e-commerce and questions whether it has successfully harmonised e-commerce laws in a way that enhances legal certainty in e-commerce transactions. It observes that, notwithstanding the adoption of the SADC Model Law on Electronic Transactions and Ecommerce, the regulation of e-commerce in most SADC countries remains archaic, fragmented and unpredictable. In order to draw lessons for the development of an e-commerce regulatory framework that enhances legal certainty and predictability in e-commerce transactions, the study explores the regulatory approach to e-commerce of various Regional Economic Communities (REC) namely the Association of Southeast Asian Nations (ASEAN), the Economic Community of West African States (ECOWAS), the East African Community (EAC) and the European Union (EU). In the end, the study proposes the development of a community law on e-commerce in SADC. It recommends some pertinent changes in the legal formulation and institutional framework of the SADC Treaty to ensure that the community law on e-commerce is adopted and implemented effectively by Member States. The study further advances that there is a need for SADC Member States to have the necessary political will and commitment to adopt and implement a community law on e-commerce. , Thesis (LLD) -- Faculty of Law, 2023

- Description: The Municipal Infrastructure Grant (MIG) was established in order to alleviate poverty and provide the environment for local economic development by providing financial assistance to municipalities for the construction of infrastructure. Many municipalities, including the O.R. Tambo District Municipality, have failed to deliver infrastructure that is adequate and long-lasting, as seen by the numerous protests that have taken place around the metropolis. With this study, the effectiveness and efficiency of Municipal Infrastructure Grant (MIG) projects supported by the Municipal Infrastructure Grant (MIG) in the O.R. Tambo District Municipality was evaluated (ORTDM). The data for this study was gathered through the use of a mixed-method research strategy. 15 people of the community completed a structured questionnaire on a Likert scale, and 13 ORTDM experts completed a semi-structured questionnaire. For analysing quantitative data, descriptive and inferential statistics were utilised, and when analysing qualitative data, a theme analysis was used. The findings of this study revealed that: • There is a disparity between theory and practice regarding the achievement of the objectives of the MIG and the implementation of M&E Systems in ORTDM. Whilst the professionals at ORTDM are knowledgeable of the processes or frameworks to ensure that all work plans and budgets are being maintained, community members are adamant that the objectives of the MIG projects are not being achieved, and M&E Systems are poorly applied at ORTDM. • There is a great disparity between the views of the professionals who believed that many strengths or merits are associated with the Monitoring and Evaluation Systems for MIG Projects at the ORTDM and the community members who revealed many inefficiencies and weaknesses in current M&E systems in MIG projects in ORTDM. • It is possible that the ORTDM is falling behind in the provision of services to its communities. • Projects that are well managed and provide economic advantages as well as better quality of life to all dwellers within their poor communities, as is the case at ORTDM, elicit greater interest and satisfaction from community members. The supply of essential utilities including drinking water, sanitary facilities, roadways, and public lighting are all included in these projects. Professionals at ORTDM had divergent views regarding compliance by ORTDM with existing M&E policy and the condition attached to MIG Funding. The professionals at ORTDM believe that ORTDM can address issues of infrastructure backlog, and the project management structure, current projects, key players and their roles, policies and guidelines that guide the overall monitoring and evaluation work are well defined. On the other hand, feedback from the community members revealed a lack of compliance by ORTDM with existing M&E policies and the condition attached to MIG Funding. In general, inadequate governance coexists with an extensive and complex regulatory framework designed to enhance outcomes in MIG projects at ORTDM. As a result, it's possible to conclude that ORTDM's generally weak governance of MIG projects is due to a lack of compliance rather than any serious regulatory deficiencies. That is, rather than a lack of legislation, governance problems are the result of officials failing to implement legal regulations. Considering the myriads of service delivery challenges that have been identified in MIG projects at ORTDM, the proposed recommendations for enhancing transparency and accountability in MIG projects at ORTDM are very significant. Recommendations such as intervention by the national treasury, enhancing community participation, physical verification of projects, strengthening of political oversight committees, etc., are crucial and extremely relevant because they emanated from the actors (ORTDM professionals) who are conversant with the challenges of the MIG projects at ORTDM. , Thesis (PhD) -- Faculty of Management and Commerce, 2023

- Description: In many parts of the developing world, participation in the management of ‘protected areas’ is among the most tangible indices of how the rural population encounters formal conservation policies, strategies and ideologies. However, some scholars have argued that the sharing of the burdens and benefits of participation is devoid of equity. While some analysts have emphasised the imperative of multi-stakeholder participation in nature conservation, citing this as a crucial socio-ecological investment, others have highlighted the inherent contradictions in the process, describing it as an avenue for manipulation, tokenism and exploitation. This study is located in this debate and focuses on narratives around the participation of different stakeholders in the management of Dwesa-Cwebe Nature Reserve and its adjacent communities in the rural Wild-Coast, Eastern Cape, South Africa. The researcher notes that research on the degrees and participation dynamics among various role players involved in the management of protected areas in South Africa, Dwesa-Cwebe Nature Reserve in particular is limited. Against this background, this study contributes to ongoing discussions on protected area management in South Africa but seeks to expand this discussion by interrogating the nature and degrees of participation within the Dwesa-Cwebe Nature Reserve - to deepen intellectual understanding on the significant role played by protected areas in engendering participatory democracy, equity, justice as well as meeting the needs of marginalised communities. Primary data for the thesis were collected using in-depth and key-informant interviews with officials from government institutions and parastatals, politicians and traditional authority figures. Focus group discussions were held with ‘youth’ participants as well as ‘elders’ in the Reserve’s adjacent communities. An analysis of policy and other government documents sought to outline the institutional attributes of protected areas management in South Africa and the underpinning ideas. A thematic analysis of the corpus of empirical information helped to show how these institutional attributes inhere in Dwesa-Cwebe Nature Reserve as well as the epistemic challenge these attributes pose vis-à-vis indigenous ecological ideas and practices in the adjacent ‘indigenous’ communities. The study revealed that participation is perceived differently by various stakeholders due to multiple, mutually contradictory impulses. While institutional stakeholders attached great importance to the structural role of institutional frameworks, hence the vigorous reliance on formal conservation strategies, narratives from community members drew attention to ‘equity deficits’. The study also found that while the selected Reserve may have fostered cooperation between government and the adjacent communities, conflict and distrust ran deep between these stakeholders. From these and other findings, the study concluded that ecological participation in the study area was characterised by clusters of stakeholders who regard one another as ‘epistemic outsiders’ and related to one another as such, with practical consequences – especially for the long-term sustainability of the Reserve. In the main, the thesis rests on the argument that in the face of epistemic differences, dominance and marginalisation could become a defining feature of protected area management that cannot be readily resolved through the mere process of participation. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2023

- Description: This 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, 2023

- Description: Globally, the increasing rate of antimicrobial resistance against our currently available drugs has been a serious public concern. Due to the selective nature of antibiotics, bacteria are expected to develop resistance against them over time, but the current scourge of antimicrobial resistance is aggravated by factors other than the expected evolutionary trend. The use and overuse of antibiotics in clinical and agricultural contexts have led to the fast rise of multidrug-resistant MDR microorganisms. A scenario that necessitates an upsurge in the clinical failures observed with our current drug arsenals is expected to rise if left unchecked. One of the significant drivers implicated in the spread of antimicrobial resistance genes is the integrons. These are mobile genetic elements found on pathogenicity islands, transposons, and plasmids, easing their distribution among various bacteria. They are considered efficient gene expression systems that naturally capture, integrate gene cassettes GCs and immediately express the captured antimicrobial resistance genes on the GCs due to the inherent promoters on their structures. Integrons have been known to confer resistance against most classes of antibiotics. These include all known β-lactams, chloramphenicol, trimethoprim, erythromycin, aminoglycosides, quinolones, streptothricin, lincomycin, rifampicin, fosfomycin, and antiseptics of the quaternary ammonium compound family. They have been detected in bacterial populations under direct or indirect antibiotic pressure in clinical, agricultural, and environmental contexts. The emergence of MDR in Enterobacteriaceae is a critical public health issue that has attracted the World Health Organization WHO, which classified them as one of the critical priority pathogens urgently requiring new antibiotics. The resistance phenomenon has proven most of the current antibiotics ineffective, further compounded by the slow pace of the discovery of new antibiotics, necessitating the hunt for new, practical remedies. One of such is the exploration of synergy among existing antibiotics. Two medications combined have a higher impact, thereby allowing current antibiotics to be salvaged for use in treating MDR bacteria, even if the bacteria are resistant against one or both antibiotics separately. Hence, this research focused on the occurrence and prevalence of multidrug resistance and the characterization of integrons and their associated gene cassettes in members of Enterobacteriaceae, including Klebsiella pneumoniae, Klebsiella oxytoca, Enterobacter cloacae, Escherichia coli, and Citrobacter spp. recovered from animal droppings, rivers, and effluents of hospital and wastewater treatment plants in Eastern Cape Province, South Africa. The inhibitory effect of combining two drugs belonging to different antibiotic classes to obtain a possible potentiating effect against some multidrug-resistant Enterobacteriaceae isolates harbouring integrons were examined and studied. The isolates were identified using the conventional molecular Polymerase Chain Reaction with specific primers. The antimicrobial resistance profile and the production of Extended-spectrum and metallo β-lactamase were detected using disk diffusion technique DDT, double-disk synergy test DDST, and ethylenediaminetetraacetic acid EDTA tests, respectively. The PCR-based screening method, DNA sequencing analyses, and restriction fragment length polymorphism RFLP were used to characterize the integrons and their associated GCs. Furthermore, Enterobacterial Repetitive Intergenic Consensus ERIC PCR determined the genotypic relationships between some specific species. The various antibiotics' minimum inhibitory concentration MIC was determined using the broth microdilution, while the checkerboard method was used to determine the fractional inhibitory concentration indices FICIs. The time-kill assays TKAs were further used to confirm the synergism observed from the checkerboard assays. Most of the isolates were resistant against most antibiotics tested and were considered MDR. The least resistance was observed against imipenem, a carbapenem, one of the drugs of last resort. Also present were the ESBL and MBL producers, with a few isolates co-producing the enzymes. A high prevalence of integrons was observed in the isolates, with class 1 integrons being the most frequently detected. Some isolates co-harboured the intI1 and intI2 genes and were classified as class1 plus 2 integrons. Although Citrobacter spp. had the least number of isolates among the Enterobacteriaceae studied, it harboured the most diverse gene cassette arrays. The various gene cassette arrays were identified as follows: For Klebsiella spp. Aac 6 Ib, aadA1 dfrA1, and dfrA1 sat2; for Citrobacter spp., dfrA5 aac3 Ib, aac6 ib, aadA1dfrA1 aadA1, aadA1-dfrA1, aadA5 dfrA17, and dfrA21-aac3-Ib; for E. coli dfrA21- aac-3-Ib, dfrA5-aac-3-Ib, aadA1 dfrA1, and aadA5 dfrA17 and for E. cloacae aadA1 dfrA1, dfrA7 dfrA21 dfrA5 aac 3 Ib, and dfrA1 sat2. The GC array dfrA1 sat2 was the only array detected in class 2 integrons which are analogous to that found in Tn7, dfrA1-sat2-aadA1, with the deletion of the last GC aadA1. These detected GCs confer resistance against aminoglycosides, including streptomycin and spectinomycin, and trimethoprim, further increasing the resistance spectrum of the bacterial species harbouring them. The detection of integrons and their associated GC and the presence of these β-lactamases is also associated with coresistance against other classes of antibiotics by bacterial species harbouring them, further limiting treatment options. The checkerboard assays combining antibiotics against these drug-resistant integron harbouring Enterobacteriaceae revealed that 26.3 percent 10 over 38 of the interactions were categorized as synergistic, while 73.7 percent 28 over 38 were indifferent. None of the combinations was antagonistic. The TKAs revealed all the synergistic interactions as bactericidal. Therefore, the combinations of gentamicin with tetracycline, ciprofloxacin, and ceftazidime against Multidrug-resistant MDR Klebsiella pneumoniae; tetracycline-ceftazidime combination against MDR Escherichia coli, colistin combinations with ceftazidime and gentamicin, and tetracycline-gentamicin combinations against MDR Citrobacter freundii may be future therapeutic alternatives. , Thesis (MSci) -- Faculty of Science and Agriculture, 2023

- Description: The study explored the implemention of inclusive education in primary schools in the uMgungundlovu area, in the province of KwaZulu-Natal, South Africa. Locally and globally, the notion of inclusive education has presented various difficulties relating to the understanding stakeholders have of inclusive education and also in terms of embracing it and implementing it in schools. Stakeholders in South Africa have experienced similar challenges regarding a clear and common understanding of inclusive education and ensuring effective implementation. Despite various reforms adopted by the South African government, learners experiencing barriers to learning have persistently suffered inadequate access to quality education and equal learning opportunities. The reviewed literature has highlighted numerous challenges that have constrained effective implementation of inclusive education in South African schools. The reviewed literature also indicated that some teachers had negative attitudes towards inclusive education, and that such attitudes were linked to the lack of clear understanding of what inclusive education was about. At the core of this study is the fact that very little is known in South Africa about the implementation of inclusive education. Therefore, this study sought to unravel how chools implement inclusive education and, in that process, contribute to a deeper understanding of this phenomenon. The study utilised the Theory of Planned Behaviour as a theoretical framework and inclusive pedagogy as a conceptual framework to explore the implementation of inclusive education in four study schools. A qualitative approach underpinned by an interpretive research paradigm was adopted. Purposive sampling techniques were used to select twenty educators, four learners experiencing barriers to learning and four parents of learners experiencing barriers to learning to participate in this study. Four techniques were used to produce qualitative data, namely, semi-structured interviews, observations, documents’ review, and focus group discussions. Semi-structured interviews with educators and learners experiencing barriers to learning were utilised to generate data in the four selected primary schools. In addition to semi structured interviews, learners were also observed during lessons. Relevant documents kept in the schools were also reviewed to augment data generated through interviews. Focus group discussions were held with four parents of the learners experiencing barriers to learning. Data were analysed employing qualitative content analysis to come up with themes. The findings revealed that there was no common understanding amongst the teachers about what constituted inclusive education. Most educators understood inclusive education as referring to accommodating all learners in the classroom to reach their potential. These educators would help all learners, including those with barriers to learning thus contributing to the implementation of inclusive education in their schools. However, the findings also revealed that some educators understood inclusive education as referring to a situation where all learners received quality education, but those with barriers to learning being accommodated in special schools or special classrooms separate from their counterparts. The findings indicated that there was a lack of knowledge about inclusive education and such a lack contributed to misunderstandings about the essence of inclusive education. In addition, teachers lacked skills in dealing with learners experiencing barriers to learning, resulting in inefficient and ineffective implementation of inclusive education. It was evident from the findings that the curriculum was inflexible and the teachers lacked capacity to customise the content to the needs of all the learners, especially those experiencing learning barriers. Therefore, for teachers to implement inclusive education, it was necessary that content had to be flexible to meet the educational needs of all learners. The findings further revealed that using various teaching methods, such as visual objects and demonstrations was helpful in adapting the rigid curriculum and making it user friendly for learners experiencing barriers to learning. In addition, the research findings revealed that group work and peer learning assisted educators to implement inclusive education. Research findings also revealed that implementing inclusive education was hindered by various systematic factors, such as lack of parental support, overcrowding in classrooms, and socioeconomic challenges. I concluded that there is a remarkable knowledge deficit that can be addressed by training, including pre-service and ongoing professional development activities for teachers. I can also conclude that based on the findings educators require training on inclusive education, beginning with teachers currently in the system. The training can then be included in the curriculum of pre-service educators so that they can obtain a clear understanding of inclusive education and thus develop positive attitudes towards inclusive education. Similarly, school management teams require training on their own so that they can be able to provide adequate and effective support to the teachers in the classrooms. Another recommendation is that educators should be capacitated and developed in inclusive education to enhance their confidence in delivering the curriculum and to handle learners experiencing barriers to learning. Similarly, it is recommended that there be a collaboration between schools, homes, and other stakeholders to assist learners experiencing barriers to learning on their education journey, thus effectively implementing inclusive education in schools. Finally, a model for the improvement of inclusive education is proposed. , Thesis (PhD) -- Faculty of Education, 2023
