- Description: Agriculture plays a paramount role in the economy of many countries including Zimbabwe where more than 70 percent of the population depends on agricultural activities for their livelihoods. Smallholder farmers’ access to agricultural credit is vital for the development and growth of Zimbabwe’s agricultural sector, hence agricultural financing is crucial in rural development. Despite the Government’s efforts to provide affordable agricultural credit services to its majority smallholder farmers’ participation is still meager. The aim of this study is to analyze agricultural financing for resettled farmers in Zimbabwe, with special focus on the command agricultural loans in the Mutare district. A multistage sampling technique was employed in this study. Firstly purposive selection of Manicaland province was carried out because it is endowed with the five natural farming regions found in Zimbabwe. The second stage involved a random selection of 4 out of 7 districts with favorable climatic conditions for maize production. Thirdly, the study also carried out a purposive selection of Mutare district among the four districts with favorable climatic conditions, given the time and financial constraints. The last stage involved the use of stratified sampling technique, where the sample was divided into two strata. Stratum 1 with A1 farmers and stratum two consisting of A2 farmers, and a random sample was selected from each stratum. The study involved 301 A1 farmers and 49 A2 farmers, making a total sample of 350 farmers used for this study. Double hurdle was employed to examine the factors influencing A1 and A2 farmers` participation in command agriculture loans in the study area. Multinomial logistic regression model was also applied to investigate the determinants of command agriculture loan repayment, while propensity score matching technique was used to examine the impacts of command agriculture loans on maize productivity and profitability of A1 and A2 farmers. The results revealed that family size, and distance from the market GMB positively influence farmers likelihood to participate in in the command agricultural loan. While family size, farmer type and distance from the market were proven to have a positive significant influence on the extent of participation in command agriculture. Also training on the command agriculture loan and gender were proven to have a negative signification influence on the extent of farmers` participation in command agriculture loan. The maximum likelihood estimates of the multinomial logistic regression revealed that age and output levels significantly influence resettled farmers` likelihood to partly pay their loans. Also, the likelihood estimates of the multinomial logistic regression showed that distance from the market and output levels have a positive influence on resettled farmers` likelihood of fully paying the command agriculture loan. Access to extension services to extension services was proven to negatively influence farmers` likelihood to fully pay the loan. The results also revealed that participating in command agriculture significantly impacted productivity at the 1 percent level, while it was not significant in the participants' profitability. The results show that participating in command agriculture increases productivity by 0.93 tonnes hectare. The study recommends the intensification of extension service supply to ensure that farmers are receiving relevant agricultural training, mainly on climate change adaptation strategies. This will help resettled farmers to adjust and adapt to their new farming environments and, in turn, have a positive impact on their production levels. Also, to improve farmers’ profitability the GMB selling price should be in American dollars USD and not paid in part RTGS and part USD, because the RTGS part is always outstripped by inflation. , Thesis (MSc) -- 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: The agricultural sector is widely recognized as a crucial factor for promoting sustainable economic development, reducing poverty, and ensuring food security in developing countries. However, in Africa, the agricultural sector continues to underperform, with growth rates falling behind the population growth, this can be attributed to various challenges, including climate change and pest infestation. This has over the years weakened the defence of crops leading to the disruptions in crop production and food security. As such, calls have been made that adoption of the agricultural technology may promote food security through high yields. This is because agricultural technology crops have improved varieties such as drought tolerance and pest resistance traits. However, adoption of improved agricultural technology in Africa has been very sluggish amongst smallholder farmers, particularly for GM seed, this is due to the on-going controversies and compliance requirements regarding GM technologies. The controversies are raised by the unknown benefits and risks associated with the adoption of GM seeds technology. Furthermore, there are mixed benefits associated with GM technology adoption as well as methodological and data gaps associated with assessment of GM impact on the farmer’s welfare. In 2016, five Bt. maize varieties trademarked TELA were developed through the WEMA project. Trials were approved and launched with smallholder farmers in various countries in Africa, and South Africa is not an exception. Several smallholder maize farmers have accessed the TELA Bt. maize varieties through local seed companies and have been producing it for the past seasons. Yet, no study that has been conducted on the impact of the GM TELA Bt. maize technology adoption on yield, income, food security and technical efficiency, hence, a need for such a study. The primary data was collected from 289 183 TELA Bt. and 106 non-TELA Bt. smallholder farmers in Mpumalanga and Limpopo provinces using convenience and snowball sampling techniques. Data were analysed using various analytical tools that included descriptive statistics, gross margin analysis, Household Dietary Diversity Score, Stochastic Frontier Model and the Propensity Score Matching, modelled through the Probit regression model. These tools were utilised to address the objectives. The descriptive statistics show that the TELA Bt. maize variety yielded 61.1 percent more maize output as compared to non-TELA Bt. maize farmers, with an average of 691kg ha and 429kg ha, respectively. The gross margin analysis showed higher subsequent income for the TELA Bt. maize farmers R2 834.93 compared to R2 124.96 for the non-TELA Bt. maize farmers. The results of the HDDS showed a marginal effect of TELA Bt. maize seed technology on food diversity. The average HDDS scores were 8.4 and 7.5 for the TELA Bt. and non-TELA Bt. maize farmers, respectively. The Stochastic Frontier Analysis SFA results revealed that both the TELA Bt. maize farmers and non-TELA Bt. maize farmers were technically inefficient. However, the TELA Bt. maize farmers were better-off than their counterparts, with mean technical efficiency scores of 0.416 and 0.328, respectively. The Propensity Score Matching PSM using the Probit model revealed that gender 0.6064, number of years in farming 0.0099 credit 1.1438 and market access 0.4427 had a positive and significant influence on the decision taken by the farmers to adopt TELA Bt. maize seed technology. However, access to extension services was found to have a negative and significant impact on the adoption of TELA Bt. maize seed technology. The Average Treatment Effect of the Treated ATT using the Nearest Neighbour Matching algorithm indicated that adoption of TELA Bt. maize technology improved farmers’ yields by 254.3kg, income by 0.36 cents and technical efficiency by 8.6 percent. There was no significant relationship observed between adoption of the GM technology and food security. Generally, the results from this study imply that adoption of GM TELA Bt. maize seed technology improves farmers’ yields, income, technical efficiency, as well as food security. The study therefore, recommends increased awareness of the GM seed technology benefits to farmers, coupled with training and capacity development to enhance adoption of seed technology towards improved farmers’ welfare. In addition, there is a need for sustained Research and Development investments towards GM seed technologies to enhance maize productivity and technical efficiency of the farmers. , Thesis (MSc) -- Faculty of Science and Agriculture, 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: 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.

- Description: The current study aimed to investigate the prevalence and seasonal changes of gastro-intestinal parasites GIP of ovine grazed don three different veld types in the communal farming areas of the Eastern Cape Province. A total of 1242 sheep faecal samples were collected monthly between January 2012 and December 2015 to investigate the prevalence and season occurrence of internal parasites. From September to November 2018, a semi-structured questionnaire survey was conducted in three agro-ecological zones, humid Wartburg, semi-humid Allen waters, and arid region Cradock commonages to investigate farmers’ knowledge of the prevalence and occurrence of GIP in sheep. The prevalence of gastro-intestinal parasites was significantly higher in the humid zone roundworms 81 percent and coccidia 37 percent, followed by the semi-humid zone roundworms 75 percent and coccidia 22 percent and the arid zone was the lowest roundworms 71 percent and coccidia 14 percent. Roundworms had significantly higher counts P 0.05 mostly in hot-wet seasons of the year spring and summer and low during dry cold months of the year autumn and winter across all veld types. The humid zone had significantly higher counts P 0.05 in the seasonal occurrence of roundworms and coccidia, followed by humid zone, and very low counts were encountered in the arid zone during the study period. Seasonal occurrence of roundworm species was significant across all veld types, 64 percent of farmers were males and 36 percent were females. The study reveals that helminths and coccidia are major causative agents causing parasitic infections in livestock production, and therefore, good animal health practices management practices including proper hygiene should be followed to prevent parasitic infection in small ruminants. , Thesis (MSc) -- 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: 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: Small businesses play an important role in the growth and success of local economies worldwide. Regrettably, the persistent issue of small business failure stems from external and internal challenges. One of the most important internal challenges is the lack of knowledge required to configure a small business to sustain performance in a dynamic environment. The business's dynamic capabilities and human resource management are vital aspects. This study investigated the mediating role of knowledge-based dynamic capabilities in the relationship between human resource management practices in small businesses, using the AMO framework, and small business performance. The research employed a quantitative approach, utilising convenience and snowball sampling techniques. It yielded valid responses from 231 small businesses in the Eastern Cape region. Statistical analysis was conducted using SPSS version 27 and AMOS version 22. The relationships were tested using the Person correlation coefficient, while simple regression models were used to test the influence of the variables within the study hypotheses. To examine the mediating effect, the Hayes Process Macro was utilised. The analysis unveiled positive and significant relationships between human resource management practices and knowledge-based dynamic capabilities with performance in small businesses. Knowledge-based dynamic capabilities and all its subcomponents also mediated the relationship between all dimensions of small business human resource management practices and performance. The implication of these findings highlights the urgent attention small businesses should give towards human resource management practices and building knowledge-based dynamic capabilities. These findings also alert policymakers and small business managers to what aspects of human resource management practices and knowledge-based dynamic capabilities should be prioritised for optimal performance in small businesses. , Thesis (MBM) -- Faculty of Management and Commerce, 2023

- Description: Small businesses play an important role in the growth and success of local economies worldwide. Regrettably, the persistent issue of small business failure stems from external and internal challenges. One of the most important internal challenges is the lack of knowledge required to configure a small business to sustain performance in a dynamic environment. The business's dynamic capabilities and human resource management are vital aspects. This study investigated the mediating role of knowledge-based dynamic capabilities in the relationship between human resource management practices in small businesses, using the AMO framework, and small business performance. The research employed a quantitative approach, utilising convenience and snowball sampling techniques. It yielded valid responses from 231 small businesses in the Eastern Cape region. Statistical analysis was conducted using SPSS version 27 and AMOS version 22. The relationships were tested using the Person correlation coefficient, while simple regression models were used to test the influence of the variables within the study hypotheses. To examine the mediating effect, the Hayes Process Macro was utilised.

- Description: Competition and access to financial services are lauded as key ingredients in the fight against poverty. While competition enhances markets, fosters innovation, productivity and growth, financial inclusion allows the poor to save, access credit and insurance thereby allowing them to meaningfully contribute to economic growth and also smooth their consumption. Moreover, competition reduces the cost of finance, thereby further expanding the availability of financial services. This suggests an important relationship between competition in the banking sector and financial inclusion. Research in this area is still in its infancy and little consensus exists on both whether the relationship is a robust one or not. There is no unanimity on the direction of causality or whether competition in the financial sector is good or bad for markets. This study examines the nexus between banking competition and financial inclusion in Upper-middle income countries. It employed a panel data set over the period 2011-2017 and Generalized Methods of Moments technique was employed to answer this enquiry. The findings of this study suggest that market power is not bad for financial inclusion in upper-middle income countries. Moreover, the study found that bank competition does not matter in banking the unbanked population in Upper-middle income countries. The implication of the findings of this study is that the focus of the policy makers should not be on policies that reduces concentration and market power in the banking sector, but be on measures that encourages contestability. The threat of entry is sufficient to make banks behave in a competitive manner. , Thesis (PhD) -- Faculty of Management and Commerce, 2023

- Description: The digital gap has been hitting rural schools across the world. This has also been witnessed in South Africa. This digital gap is a result of inequality amongst households. Hence, learners and teachers from rural schools cannot access technologies as urban learners and teachers do. This situation has caused a lack of connectivity, lack of information about ICT, lack of resources, and lack of skilled teachers in rural schools. Globally, almost all countries have shifted to do things online. However, some countries struggled to shift successfully such as India. The introduction of elearning in South African government schools was done with the aim of improving results performance and to develop skills in learners and allow a flexible learning environment. In some urban and semi-urban areas, teachers are able to use new technologies to teach; however, rural teachers are bound to use traditional teaching only. The problem actually surfaced when the new pandemic known as COVID-19 started in Wuhan, China, in 2019 and spread across the world. This also affected the South African education systems, where teachers and learners were ordered to stay away from school premises and institutions, as way of preventing the virus from spreading. Rural teachers could not perform any academic activities, like urban schools did, to reach out to their learners as they wished because of the challenges stated above. Using e-learning during the 2020 pandemic was an unending nightmare for these rural teachers as they faced more challenges than those that had existed prior to COVID-19. The identified challenges discussed in this paper are those that were experienced by Alfred Nzo district teachers. This paper also refers to how e-learning was used by these teachers. Challenges identified in the literature were addressed through guidance of the UTUAT model which was adopted for the study. Each problem was categorised in line with UTUAT model four construct. The two branches of philosophies were brought in which are ontology and epistemology. Ontology asks question about the reality or existence of something and epistemology asks question about proving he existence of something. This study adopted the qualitative approach and followed that approach in terms of research paradigm, data sampling, data collection and analysis and techniques. Interviews were conducted with 15 teachers (teachers, head of department, school principal and subject advisor) from high and primary school levels, after the consent forms had been issued to obtain permission to proceed with interviews. Notes and audio recordings were made use of during interview sessions for data analysis purposes, with NVivo being used to analyse the data. Form the issues identified, these are the themes that were created which are:poor understanding of the concept “e-learning” by rural educators, high levels of resistance from educators, pedagogy of educators, insufficient support of the concept “e-learning”, poor implementation of e-learning. Lastly, after the data had been collected and analysed, this study developed five new success factors that should be implemented by the Department of Basic Education (DBE) to address issues identified as themes after thorough analysis of the literature and interviews. , Thesis (MIS) -- Faculty of Management and Commerce, 2023

- Description: This research study explores the impact of risky cybersecurity behaviours on effectively utilising High-Performance Computing Systems within Historically Disadvantaged Institutions in South Africa. The investigation utilises the Theory of Planned Behaviour and the Security Behaviour Intentions Scale to examine the attitudes, intentions, and actual usage patterns of High-Performance Computing Systems among students and staff members. Following the positivism paradigm, this study formulated hypotheses aimed at achieving the objectives. The research sample comprised of 306 users of High-Performance Computing systems selected through the convenience sampling. Employing a quantitative approach, the study used a crosssectional survey research design to collect and analyse data to achieve the study's objectives. The study's findings revealed a significant negative relationship between risky cybersecurity behaviours and attitudes toward High-Performance Computing Systems, highlighting the adverse impact of such behaviours on users' perceptions and acceptance of these systems. However, an insignificant relationship was found between attitudes toward High-Performance Computing Systems and the intention to use them. This suggests that attitudes alone may not substantially influence user behaviour in this context, contradicting the initially proposed relationship. Furthermore, the investigation identified an insignificant correlation between the intention to use High-Performance Computing Systems and the actual utilization of these systems, indicating a gap between intention and behaviour. This implies that the study's hypothesized relationship between these latent variables was not supported. Lastly, a noteworthy correlation emerged between social influence and the effective use of High- Performance Computing Systems, supporting the relationship between these variables. In summary, this research significantly enhances comprehension of the challenges and repercussions associated with cybersecurity behaviour in adopting and utilising High- Performance Computing Systems across five South African Historically Disadvantaged Institutions. It underscores the importance of addressing risky behaviours, enhancing user education, and implementing secure systems. These actions are essential for fostering the effective utilisation of High-Performance Computing Systems and unlocking their potential benefits for economic growth and educational advancements in South Africa. , Thesis (MIS) -- 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
