- 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: 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 financial sector plays a pivotal role in an economy of a country; hence the importance of financial sector development cannot be underestimated. Financial sector development is widely regarded as another conduit through which financial innovation and economic growth can be alleviated. The study firstly empirically examines the effect of financial sector development on financial innovation and also the impact of financial sector development and financial innovation on economic growth in selected Southern African Development Community (SADC) countries, employing the Generalized Method of Moments (GMM) technique for the period 1990 to 2020. Empirical results revealed that financial sector development overall does have an impact on financial innovation in the selected SADC countries. And also, financial sector development together with financial innovation does have an impact on economic growth in the selected SADC countries. However, on the relationship between financial system stability, financial innovation and economic growth, results reveal that a stable financial system is beneficial to new technological advancement and improved economic growth. Therefore, the overall findings from the study indicate that financial access or financial inclusion and financial stability is what increases financial innovation and boosts economic growth instead of mere financial sector development at a broader level. , Thesis (MCom) -- Faculty of Management and Commerce, 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 endeavoured to investigate the perspectives of principals and practitioners working in selected early childhood development (ECD) centres in the Buffalo Municipal District in the Eastern Cape, on the use of play-based techniques in educational and pedagogical practices of 3 to 4 years age group. Although most practitioners are aware of the significance of play-based learning, many report experiencing challenges when attempting to incorporate play-based strategies into their teaching of, and lessons aimed at, young children ages 3 to 4 years. For the purpose of ECD, it is recommended that the teaching of, and learning by, young children take the form of play (NCF, DBE, 2015). In this particular research undertaking, a qualitative design approach was adopted. A descriptive case study approach with semi-structured interviews as the key method of data generation was used to study play-based approaches between practitioners and children ages birth to four years at three ECD centres located within the Buffalo City Municipality District. Face-to-face interviews were conducted with the three principals of the ECD centres and six practitioners, during the data-collection phase. Recording of the interviews was done then they were transcribed and thematic coding employed before the data were analysed for themes. The study participants’ responses revealed that the insufficient professional training of practitioners, on play-based approaches, presented a challenge. Play as a way of teaching and developing young children is further hampered by a variety of issues such as poor infrastructure, unqualified practitioners, funding of the ECD centres and lack of relevant resources prevalent in the ECD sector. As the findings indicate, government intervention will facilitate the training of practitioners for in-depth knowledge and understanding of play methodology in ECD, while the sector will benefit from additional funding and infrastructure provision as this has impact on indoor and outdoor play-based activities, as well as the appointment of qualified human resources instead of job seekers. , Thesis (MEd) -- Faculty of Education, 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.

- 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.

- 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 contamination of lotic ecosystems caused by agricultural, industrial, and anthropogenic activities has attracted the attention of researchers, authorities, and scientists because these waterbodies are of social and economic importance to human livelihoods. Pesticides and insecticides are a group of compounds that are toxic to pests and insects, respectively. Organophosphate pesticides (OPs) can be released into different environmental matrices through several sources including agricultural and urban runoff. They are one of the three main classes of synthetic organic pesticides that are used in agricultural sector and very often end up in other destinations than their target sites. In this study, four OPs, namely, ronnel, malathion, parathion and Durban were investigated. The Buffalo River Estuary, located in East London, is one of most popular areas and the river is a major source of raw water abstraction for three municipalities in the Eastern Cape Province, South Africa. Sediment samples were collected from six points in the estuary and soil samples were taken from a nearby dumpsite in winter and spring seasons of 2021. The physicochemical parameters of the samples including particle size, moisture content, oil and grease and organic carbon were determined. The samples were then extracted by ultra-sonication, the final extracts were analyzed using GC-μECD and the risk quotient (RQ) method was used to evaluate the risk of OP exposure to aquatic organisms. Polymer modified cyclodextrin (β-CD) for the removal of parathion in sediment and soil was synthesized and the morphology of the modified β-CD and vibrations of the synthesized material were determined using scanning electron microscope (SEM) and Fourier transform infrared (FTIR) spectroscopy, respectively. The limit of detection (LOD) and the limit of quantification (LOQ) of the OPs investigated were in the range of 0.09 to 2.99 and 0.274 to 9.06 μg/L, respectively. OPs gave a good recovery except for malathion, which had a recovery percentage lower than 70%. Calibration curves were plotted for the four OPs and were linear with relative standard deviations (RSD) ranging from 1.02 to 3.50, and correlation coefficients (R2) ranging from 0.9935 to 0.9972. The mean concentrations for sediments and soil in both seasons varied from 0.00231 to 63.8 μg/g in winter and from 0.0017 to 36.6 μg/g in spring, with malathion being the predominant congener and dursban being the least dominant in both seasons. In winter, the particle size percentages of the sediment and soil samples ranged from 34.4 to 79.4 percentage, 15.4 to 23.9 percentage and from 7.77 to 38.3 percentage for coarse, medium, and fine fractions, respectively. While in spring, the particle size for the course, medium and fine mesh fractions ranged from 37.4 to 74.6 percentage, 14.1 to 25.1 percentage and 12.4 to 35.0 percentage respectively; the percentage moisture content varied from 43.0 to 73.1 in winter, and from 57.1 to 63.4 in spring. In the soil samples, the physicochemical properties were lower in winter except for the n- hexane extractable material (HEM), which significantly decreased in spring from 2.6 to 1.63 mg/kg; while for sediments, the oil and grease ranged from 1.77 to 10.3 mg/kg in winter and from 1.63 to 4.28 mg/kg in spring. The risk quotient method was used to determine the risk of OP exposure to sediment-dwelling organisms and the results obtained indicated that the levels of OPs in this study, especially dursban, can pose a high risk to the organisms in sediments, with RQs higher than ten (˃10) in both winter and summer. The Pearson product-moment correlation showed that parathion had a weak correlation with every other variable except for malathion in winter, whereas in spring, parathion correlated very weakly with malathion; suggesting that products containing parathion are mostly used to control pests found in crops, such as corn and mosquitos, which are most active in the spring season. There was a very strong correlation between dursban and ronnel in spring and winter, implying that an increase in dursban concentration resulted in an increase in the concentration of ronnel. To determine the efficiency of the synthesized adsorbent CD-chitosan-alginate for the removal of Parathion from soil and sediment, different parameters such as concentration, time, pH and dose were varied. The adsorption capacity was found to be highest at pH 2 (99.19 percentage), when 3 mL of the adsorbent was used for 30 minutes. , Thesis (Msci) -- Faculty of Science and Agriculture, 2023

- Description: Water and sanitation are basic human needs. It is also a constitutional right for all citizens in South Africa to have access to both water and sanitation. Supply of water and sanitation services in South Africa is characterised by both achievements and challenges. As informed by literature, in South Africa it is evident that water and sanitation still hold many challenges in poor communities, particularly in informal settlements. This study was conducted with the purpose of evaluating water and sanitation challenges in the informal settlements of Duncan Village and make recommendations, where applicable, to the local municipality for possible remedies. Despite the provision of water and sanitation by the Buffalo City Metro Municipality, the study reveals that there are serious water and sanitation challenges in Duncan Village. High water losses, illegal water connections, illegal sanitation connections causing sewer spillages, vandalism of both water and sanitation service infrastructure, and lack of operations and maintenance are identified as the key water and sanitation challenges. According to the findings, the causes of these challenges include the municipality's lack of proper planning for informal settlements; lack of visibility of municipal water and sanitation officials in informal settlements; lack of awareness; lack of public participation; overpopulation; lack of monitoring; and lack of operations and maintenance budget to help keep the provided facilities intact and usable. The study's key recommendations include intense involvement of the municipality and the ward councillors, ownership by the residents, monitoring of water and sanitation facilities, operations and maintenance, and formalising Duncan Village informal settlements. This was accomplished using questionnaires to gather, analyse, and interpret the collected data. The study targeted residents, ward councillors, and a municipal officer from the municipality's Water and Sanitation section as respondents , Thesis (MSci) -- Faculty of Science and Agriculture, 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: The application of Information and Communication Technologies (ICT) in agriculture can augment farmers' production capabilities, this is a perception for all farmers worldwide, but there are some in communal areas who may not be as exposed to ICT tools as their commercial counterparts in urban areas, especially in developed communities. Food security in any society is a vital measure that should always be treated with high priority since humankind's existence is based on food availability. One major challenge with farmers in communal areas has been the marketing of their farm produce effectively to avoid wastage, get more value, and bridge the gap between themselves and urban commercial farmers. This challenge includes food wastage, untimely information, and market accessibility due to distance restraint. ICT can beused to bring a functional platform to assist this challenge. In this context, communal farmers have a challenge. The aim of this research was to design and develop an easy-to-use mobilebased e-marketing application for marketing farm products for communal farmers in Alice community, South Africa. Before design and development, review of challenges of farmers on the reception and communication of sensitive information pertaining to food security. Effective communication of farm produce baseline information on awareness and adaptation of mobile ICT technology of communal farmers was investigated. A mixed method was used through reviews of literature and as well distribution of questionnaires to get an understanding of the present state of communal farmers’ marketing problems. Furthermore, a prototyping methodology was used in the development of the mobile-based application for this research. The result of this research demonstrated the need for communal farmers to market their farm products at their convenience. An easy-to-use mobile-based e-market application was then developed; the application is an android application that will assist communal farmers in marketing their farm products as soon as they are available to avoid food wastage. The application performance and evaluation assessment indicated that the tool would maximize farm productivity and profitability and, facilitate concise and effective access to the market, as well as eliminate the need for an intermediary. , Thesis (MSci) -- Faculty of Science and Agriculture, 2023

- Description: This study aimed to exam the implementation of the Department of Social Development’s Fatherhood Strategy by Families South Africa (FAMSA) Eastern Cape. FAMSA is a non-profit organization providing vital services to people in families while providing them with psychosocial and emotional support. FAMSA has been in existence since 1954. To achieve this aim, the study’s objectives were underpinned by understanding the implementation of the Department of Social Development’s Fatherhood Strategy in Buffalo City Metro, establishing FAMSA’s response to the implementation of the Department of Social Development’s Fatherhood Strategy as well as exploring the challenges faced by FAMSA in implementing the Department of Social Development’s Fatherhood Strategy. A qualitative research methodology was implemented to gather information from FAMSA and DSD. Findings from literature revealed that the fatherhood strategy has been a concern worldwide evidenced by the high levels of father-child non-residency. Data from this study revealed that FAMSA had been implementing the programme effectively regardless of numerous challenges that include funding human resources. Conclusively, a lot must be done to advocate for fatherhood. Recommendations also point to the need for several interventions which need to be done in research, social work practice and also policy formulation and development. , Thesis (MA) -- Faculty of Social Sciences and Humanities, 2023

- Description: Wheat is generally one of the dominant crops globally, being mainly used for human food and livestock feed. Due to climate change, drought makes it challenging to produce enough wheat mostly under dryland production regions in South Africa. Drought stress has severely reduced wheat yield by up to 70 percent, and adversely compromised wheat grain quality. The adoption of drought-tolerant cultivars offers a sustainable and low-cost solution for increasing wheat yields and minimise importing the crop to meet national requirements. The main objective of this study was to investigate the response of different wheat genotypes to drought and optimum conditions in the Eastern Cape Province, South Africa. Forty diverse wheat genotypes were evaluated in this study. The specific objectives were: (i) to evaluate the response of wheat genotypes under optimum and drought-stressed field conditions; (ii) to determine the effect of terminal drought stress on wheat grain quality composition; and (iii) to identify appropriate drought tolerance indices that can be used as selection tools under field conditions. This study was conducted in the field using a 5x8 alpha lattice design, replicated twice under two water regimes (drought and optimum) over two consecutive winter seasons of 2020 and 2021 at two different sites namely University of Fort Hare Research Farm in Alice, and Zanyokwe irrigation scheme in Keiskamahoek. Drought stress was imposed from 50% flowering up to physiological maturity. Data on agro-physiological traits such as duration to heading (DTH); flowering (DTF); maturity (DTM); plant height (HT); spike length (SL); number of spikelets per spike (SPS); kernels per spike (KPS); and grain yield (GY (kg/ha)) was subjected to the analysis of variance using Genstat 18th edition. As the study took place over two sites, a combined ANOVA table revealed significant differences (p0.001) among genotypes, and all interactions such as genotype by water regime (GWR); genotype by seasons (GS) for all studied traits. Notably, the extent and severity of drought differed between geographical regions and between seasons. This necessitated the adoption of the additive main effect and multiplicative interaction analysis (AMMI) for the identification of stable genotypes under two different water regimes over two sites. Regarding grain yield, superior and/or stable genotypes included G5 (4334 kg/ha under optimum, and 2871kg/ha under drought), and G22 (4418 kg/ha under optimum, and 2624kg/ha under drought) at the UFH site. G21 (3194 kg/ha under optimum, and 2938 kg/ha under drought), G33 (2552kg/ha under optimum, and 3810 kg/ha under drought), and G35 (2688 kg/ha under optimum, and 3309 kg/ha under drought) at the ZAN site. Stable genotypes across sites included G21 and G33. There were generally weak correlations between agro-physiological traits and grain yield. From the experiment, grain quality traits such as fixed protein (PF); wet gluten (WG); hectolitre mass (HLM); and thousand kernel weight (TKW) were also examined. A combined ANOVA revealed significant differences (p0.001) among the interaction of genotypes by environments (GE) for all traits except PF. This implies that the performance of wheat genotypes across sites was also different, and therefore, necessitated separate analysis of variance for each site. Significant differences (p0.001) among genotypes (G), water regimes (WR), and the interaction of genotypes by water regime (GWR) were observed for all studied quality traits except PF in both sites. GWR showed no significant differences for TKW in the ZAN site. The stability in the performance of genotypes across water regimes was further determined. G38 was stable for wet gluten; G31 and G26 were stable for PF; G36 was stable for HLM; and G11, G15, and G29 were stable for TKW at the UFH site. G6 was stable for both WG and PF; G13 and G15 were stable for HLM; and G35, G21, and G40 were stable for TKW at the ZAN site. These results suggest that the quality of wheat grains was affected under drought stress conditions except PF. Average grain yield data under both stressed (Ys) and optimum (Yp) conditions was used to compute a number of different drought tolerance indices. These include mean productivity (MP); geometric mean productivity (GMP); harmonic mean (HM); Tolerance index (TOL), stress susceptible index (SSI), sensitive drought index (SDI), and stress tolerance index (STI). The aim was to identify appropriate drought tolerance indices that can be used as selection tools under drought stress. MP, GMP, and HM were the more appropriate indices as they had a strong and positive correlation with grain yield under both drought and optimum conditions. However, genotypes G5, G22, G8, and G21 were more tolerant and stable as they showed high mean values. Based on the results, G19, G16, G2, and G20 were more sensitive to drought as they showed low values of MP, GMP, and HM. Overall, genotype: G5, G21, G22, and G33 are recommended for production under drought and optimum conditions, as they showed stable performance across water regimes. Principal component analysis also revealed that MP, GMP, and HM were the only indices that had positive loadings into the first principal component. , Thesis (MSc) -- Faculty of Science and Agriculture, 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.

- 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: The yellowtail kingfish, Seriola lalandi, is a carnivorous species, which require high levels 40 Percent of protein in its diet of which a significant portion comes from fishmeal. Fishmeal is usually the main ingredient when formulating a diet for carnivorous fish because of its high protein content, good digestibility and balanced essential amino acid profile. The use of fishmeal in diet formulations has decreased because of high prices and short supply. Aquaculturists have little alternative but to reduce the amount used or replace it with alternative suitable protein sources. This study aimed to contribute to the optimization of protein requirements and fishmeal replacement in the diet of juvenile yellowtail in a Recirculating Aquaculture System RAS. This study was conducted at the marine finfish farm, Kingfish Enterprises Pty Ltd in the East London Industrial Development Zone ELIDZ in a purpose designed RAS. The first experiment investigated the effect of dietary protein level on survival, growth, food conversion ratio FCR and health of juvenile yellowtail in a RAS. Four iso-calorific diets containing different dietary protein levels 38 Percent , 44 Percent , 50 Percent and 56 Percent were formulated. Each diet was fed to three RAS tanks holding juvenile yellowtail 30 fish per tank for 49 days. Dietary protein levels did not influence survival of juvenile yellowtail. Specific growth rate SGR p equal 0.003) was greater in fish fed 56 Percent protein compared to fish fed 38 Percent protein but there were no differences between the 56 Percent , 50 Percent and 44 Percent protein diets. There were no differences in protein efficiency ratio PER between the four diets. FCR decreased with increasing protein level with fish being fed the 56 Percent protein yielding the lowest FCR 1.26 compared to fish fed 38 Percent protein 1.76 p equal 0.003, however, there was no difference between the 44 Percent , 50 Percent and 56 Percent protein levels. The hepatocytes of fish fed high dietary lipid content diet with 38 Percent and 44 Percent protein showed large lipid vacuole zones in the cytoplasm p greater 0.001. Body protein, ash, moisture, and lipid was not affected by different dietary protein levels. In terms of producing a diet with best growth at the lowest cost, a 44 Percent protein diet is considered as optimal for juvenile yellowtail in RAS. The second experiment investigated the effect of partial and full replacement of fishmeal with a mixture of alternative protein sources chicken meal, blood meal, and soybean meal in equal proportions that are more sustainable and less costly. Four experimental diets were formulated to be iso-nitrogenous 44 Percent protein and iso-calorific 19.50 Mg/Kg as follows: 1 a control diet with fishmeal as the only protein source which was the same formulation as the 44 Percent diet used in the first experiment, 2 control diet in which 33 Percent of fishmeal was replaced with the protein mixture, 3 control diet in which 67 Percent of fishmeal was replaced with the protein mixture and 4 control diet in which 100 Percent of fishmeal was replaced with the protein mixture. Different fishmeal levels in the diets did not have an effect on the survival on juvenile yellowtail. Specific growth rate SGR was greater for fish fed 67 and 100 Percent fishmeal p equal 0.017 compared to fish fed 0 Percent fishmeal. There were, however, no differences in SGR between fish fed 33, 67, and 100 Percent fishmeal. Condition factor CF was significantly affected by the interaction between dietary treatment and time with average values lower at the end of experiment compared to the start of the experiment. On day 28 p equal 0.02 and 49 p equal 0.01, CF of fish fed 67 and 100 Percent fishmeal diet differed significantly from those fed the 0 Percent fishmeal diet but 33, 67, and 100 Percent fishmeal diets did not differ from each other . Feed conversion ratio FCR was significantly affected by fishmeal replacement with fish on fishmeal-containing diets showing lower FCRs compared to those on fishmeal-free diets p equal 0.001. Fish fed diets containing 67 and 100 Percent fishmeal had low PER 0.026 compared to fish fed 0 Percent fishmeal. There were, however, no differences in PER between fish fed 33, 67, and 100 Percent fishmeal. Hepatosomatic index HSI was not affected by levels of fishmeal replacement in the diet. Body protein, ash, moisture, and lipid was not affected by partial and full replacement of fishmeal. The results indicate that full replacement of fishmeal 0 Percent diet had the worst SGR, FCR, and PER. The remaining three diets were statistically similar which suggests that a diet with 33 Percent fishmeal produces as good growth, FCR and PER as 67 and 100 Percent fishmeal diets. However, as there were also similarities in SGR and PER for the 0 and 33 Percent fishmeal diets, it is therefore recommended that future studies focus on the region between 33-67 Percent to find the optimal break point for the various growth indicators. This study has provided foundation for the formulation of yellowtail kingfish diet which is suitable for use in a RAS. , Thesis (MSci) -- Faculty of Science and Agriculture, 2023
