- 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: 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

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: 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

- 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

- Description: Regulatory authorities have to date utilised a strategic blend of fiscal and monetary policies in dealing with the unique set of macroeconomic conditions facing South Africa. Government policy intervention has significant implications for economic growth and output within the manufacturing environment. Heterogeneity has also been discerned in relation to the responsiveness of various industries within the manufacturing sector towards both fiscal and monetary policy variable variations. However, given weakened growth prospects, policy alignment issues have been observed. The purpose of this study was firstly, to examine the impact of fiscal and monetary variables on manufacturing sector output in South Africa and secondly, to analyse the manufacturing industry significance of the various monetary transmission mechanism channels. The study made use of quarterly and monthly data to achieve these stated objectives, dated between 1998 and 2020. To achieve the first objective, the study employed the Autoregressive Distributed Lag (ARDL) model given the order of integration of the variables. The empirical results revealed significant, positive relations between tax revenue, deficit financing, nominal effective exchange rate (NEER) and money supply (M3) for total manufacturing (LTOTAL). Contrastingly, there were negative links between LTOTAL, government spending and the lending rate. At a disaggregated industry level, there were positive relations with tax revenue in food and wood industries, although tax revenue was significantly negative for metals. Likewise, to LTOTAL, linkages with spending were significantly negative for wood and metal industries but positive for chemicals. Negative spending signage could be a result of crowding-out. For deficit financing, positive associations within chemicals did not conform to expectations. Similarly, to LTOTAL, wood and metal industries conformed to expectations of negative relations with the lending rate. In respect of the NEER in food and wood production, significant, positive links were established. Contrastingly, a negative linkage existed for chemical activities at the 5% level. Concerning M3 and akin to LTOTAL, the relation with metal industries was positive. However, negative findings for food and chemicals contradicted expectations, suggesting money supply was not efficiently utilised in managing monetary variables in the long-term. The second objective of the study focused on analysing manufacturing industry significance of the various monetary transmission mechanism channels. The Vector Error Correction Model (VECM) were employed to analyse the relationship between the variables. Impulse response and variance decomposition were also constructed to further trace which channel is more significant in influencing manufacturing output. The empirical results revealed that the interest rate channel occupied a relatively significant role in both LTOTAL and several selected manufacturing industries. Shocks accounted for 9.71%, 11.96% and 14.28% of the variance in LTOTAL, metal and chemical industries. The asset price channel also appeared relatively significant, with shocks to the FTSE/JSE all-share index explaining 18.21% and 21.13% of the variation in food and wood production, signifying the most relevant channel for these particular industries and representing the second most important channel for LTOTAL and the other remaining industries. The exchange rate channel also presented as being a more relevant channel for food and wood, but occupied little role in LTOTAL, whilst the credit channel was relatively ineffectual for both LTOTAL and all industries examined. The results obtained imply that government should exercise caution and demonstrate fiscal restraint and that the South African Reserve Bank (SARB) need to take greater consideration of output fluctuations in monetary policy setting. Research has dictated that an expansionary fiscal policy is generally required as a means to achieving increased growth. However, findings obtained at both the aggregate and disaggregated manufacturing level in South Africa largely varied. This implies significant heterogeneity within the South African manufacturing sector in respect of fiscal policy responses. Expansionary fiscal stimulus packages need to be better targeted towards industries that will most benefit. Similarly, monetary policy responses at the aggregate and disaggregated manufacturing level in South Africa were heterogeneous and furthermore, differed when examining combined policy impacts. There was also a heterogeneous response with respect to relevance of the channels, via which monetary policy operated, with the interest rate channel dominating. SARB do take into consideration output fluctuations in policy setting but this is not currently emphasised or legislated. , Thesis (DCom) -- Faculty of Management and Commerce, 2023

- Description: The study was carried out to investigate the training of pre-service Science teachers in the integration of Information and Communication Technology (ICT) in Science teaching at two colleges of education in the Volta region of Ghana. The study aimed to recommend a framework that can be used to enhance the training in ICT integration competencies of pre-service Science teachers at colleges of education in the country. The study was underpinned by two theoretical frameworks: Rogan and Grayson’s curriculum implementation framework and Guzman and Nussbaum’s ICT integration framework and was located within the interpretive paradigm. The qualitative research approach was adopted to generate data on the types of ICT integration competences that pre-service Science teachers are trained in, the pedagogical strategies used, the support provided, and the challenges faced during the training. The study adopted the explanatory case study design. Convenience and purposive sampling were used to select the study sites and participants respectively, which consisted of two teacher education colleges, two heads of Science department, ten lecturers, and 20 pre-service Science teachers. The study’s data collection methods were semi-structured face-to-face interviews with the lecturers, focus group discussions with the pre-service Science teachers, non-participatory lesson observation, and document analysis. The data was analysed using thematic approach. The study established that pre-service Science teachers at the two colleges received training in mastering the usage of ICT tools, relating ICT to teaching; using ICT for assessment and providing feedback, creating an appropriate environment for ICT integration, and developing positive attitudes toward ICT usage. The study revealed the pedagogical strategies used for training the pre-service Science teachers in ICT integration competencies to include a standalone ICT course, demonstration, group work, self-learning and how assessment is carried out. The study also established that there was support from both within and without the college environment in training pre-service Science teachers, although this was inadequate. The major challenges found by the study to be hindering effective pre-service teacher training in ICT integration competencies were lack of technical know-how among lecturers, poor pre-service Science teachers’ backgrounds in ICT, inadequate ICT resources and infrastructure, prolonged organisational and management bureaucracy, and insufficient funding of ICT. The recommendations made included the need for upgrading infrastructure in the colleges while also upgrading lecturers’ competencies in handling ICT in the colleges. An alternative training framework for preparing pre-service Science teachers in ICT integration competencies was also proposed. , Thesis (MEd) -- Faculty of Education, 2023

- Description: This study was prompted by the observation that learners’ performance in mathematics is low in South Africa. Several factors such as teachers’ qualifications, demotivated learners, and limited school resources have been raised and considered. Although number sense forms the foundation blocks for mathematics understanding, limited academic work has been done to explore implementable mathematics instructional interventions for the enhancement of understanding number sense. The purpose of this study was to contribute an implementable mathematics intervention framework for understanding number sense. Since the study focused on exploring intervention activities, it was guided by the pragmatism research philosophy. Data were captured from purposive samples of teachers and stratified samples of 1050 learners from schools in the Ekurhuleni North district in South Africa. The research design comprises the following sequence: survey, pre-test, intervention, post-test, and evaluation by teachers’ focus group discussion. These activities were carried out parallel to document analysis, which provided bench marks. The main data-capturing instruments were the questionnaires, learners’ test, interview, and document analysis guides. Factors analysis to establish associations, differences, and regression was carried out using SPSS and Excel. The study found that: almost all teachers implemented some form of mathematics interventions. Continuous assessment was the main intervention, followed by problem-solving, and the use of games (which was least preferred). Teachers shunned games because they require more time and management skills. Challenges that teachers experienced when implementing mathematics interventions include their limited knowledge and the lack of resources and support from education authorities who expect and emphasise high pass rates in mathematics. The teachers’ focus group discussions evaluated the intervention and proposed the following sequence for instructional intervention on number sense: Stage 1: parroting of number names, for example, six, two, nine and seven Stage 2: symbolic identification, for example, the symbol 6, 2, 9 and 7 Stage 3: association where a learner group six stones, shows two fingers, etc. Stage 4: seriating or ordering done through oral counting and use of inequality symbols: () to compare and estimate values in problems Stage 5: the four operations for addition (+), subtraction (-), multiplication (x) and division (÷) emphasizing estimation and application. The study recommends the adoption, modification and implementation of mathematics intervention framework to enhance number sense. , Thesis (MEd) -- Faculty of Education, 2022

- Description: Climate change is a threat to communal livestock production, causing increases in the rate and intensity of droughts, floods, pests and diseases, and thus subjecting communal livestock production to vulnerability. Communal farmers rely on rain-fed agriculture and are usually too poorly resourced to cope with the frequency of climate-related events that may be expected in the future. Response and adaptation is vital to ensure the sustainability of livestock production, particularly since it is the main source of survival in communal areas. The Eastern Cape Provincial Policy on Climate Change was introduced in 2010 to facilitate a coordinated approach that assists farmers to respond, adapt and mitigate climate change. The study examines the implementation of the policy to identify farmers’ perceptions of the response rate prior to, during and after climate change disasters. In addition, the study establishes the characteristics of livestock production in the study area, seeking to ascertain how communal livestock farmers CLFs are adapting their practices to ensure sustainable livestock production in the face of climate change. In order to make informed decisions on coping strategies, farmers require access to information on climate change. The study therefore examines the communication channels used by farmers to access such information. Since food security is under threat, the study also assesses the effects of climate change on food security among the CLFs. Multi stage sampling was used to select 388 communal livestock farmers in three local municipalities in Amathole District Municipality. A cross-sectional survey was carried out in five communities randomly selected in the three local municipalities, with data collected by means of a semi-structured questionnaire. Descriptive statistics, inferential statistics, principal component analysis and regression methods were used to analyse the data. The study reveals that communal livestock farmers perceive a poor response rate from extension services before, during and after disasters, and that they have poor access to support materials. All of the respondents practised uncontrolled breeding, attributed to a lack of infrastructure such as fencing. Most farmers kept cattle for income generation. The major constraints of cattle production were diseases and pests. CLFs employed dipping, rotational grazing, water tanks, veld burning and the sale of animals as the main strategies to cope with climate change. CLFs access climate change information through multiple channels. The main sources were other farmers and media such as radio and television, although language barriers hampered full understanding of information conveyed about climate chnage. Farmer-to-farmer contact was a central aspect of the CLFs’ lives that could be better employed in the dissemination of climate change information. The results suggest a positive relationship between diversity of species kept and food security. Assets, the social safety net (mainly grants) and adaptive capacity indicators positively and significantly impacted households’ resilience to food insecurity. The study recommends that the capacity of communal livestock farmers on effective mitigating strategies be improved, making use of mass media; that more work be done by extension services to prepare farmers for adverse events and that relief materials disseminated during periods of disaster be tagged “national emergency” to speed up distribution and use. There is an urgent need for adequate and timely provision of climate change information that will help CLFs to make more effective use of their resources in the face of climate change. Agricultural extension services should address challenges associated with breeding practices, disaster response and adult illiteracy to promote better adaptive capacity and ensure food security among this vulnerable cohort. , Thesis (MSci) -- Faculty of Science and Agriculture, 2022
