- Description: The research presented in this thesis is based on my interest and experience in forms of African music, ethnomusicology, and studying mbira with Professor Emeritus Andrew Tracey. When I arrived in South Africa in 2019 to join Rhodes University’s Applied Ethnomusicology programme, I chose to study the mbira with Tracey as the idea of learning more about Zimbabwe through music was important to the formation of my identity. Through the lens of embodied learning and a practice-based approach in this research, I evaluate how Tracey’s numerous contributions to African music pedagogy have improved prospects for African music scholars and students in terms of contributing to the goals of applied ethnomusicology. The primary purpose of this thesis is to respond to the absence of serious scrutiny of existing pedagogical approaches to African music at universities across South Africa. The contribution this research makes will be valuable to African music programmes across the continent as well as to practitioners of African traditional instruments, such as the marimba, mbira, timbila xylophones, nyanga pan pipes, and valimba xylophones. The thesis comprises five chapters. The first presents an introduction to the research, and its goals, procedures and approaches, along with an outline of the subsequent chapters. Tracey’s biography is covered in the second chapter. A consideration of the state of African music teaching in other African countries such as Ghana, Kenya, and Zimbabwe; the history of African music; and the state of African music pedagogy in tertiary institutions in South Africa constitutes the third chapter. Chapter 4 comprises an analysis of Tracey’s articles and data gathered from interviews, as well as my personal reflections as Tracey’s student. The final chapter presents a summary of the preceding chapters, the study’s findings, and suggestions for further research. A multidisciplinary approach was used for this thesis. The results finds that Tracey’s articles had six common themes which he wrote about and are a contribution to African music pedagogy. These themes are the history of instruments, the structure of the instrument, the learning/playing technique, structure of the instrument, transcription and dance steps. , Thesis (MMus) -- Faculty of Humanities, Music and Musicology, 2022

- Description: Provincial government departments do not have good audit reports on the information security section. The underlying issues are human factors associated with employee interaction with Information and Communication Technology (ICT). The problem to be addressed is how a provincial government needs to focus on employees’ information security awareness so that there is a residual improvement in information security culture to realise unqualified government audits for information security. A case study approach that focused on the provincial government departments in the Eastern Cape Province was used. The primary data was collected using semi-structured interviews containing questions related to information security awareness. Microsoft Teams was used to conduct online semi-structured interviews with 12 provincial government IT staff from two identified provincial departments. The data was analysed using thematic analysis and MS Excel for coding. The findings then were used to determine the outcome of this study which is the framework for preparing an information security awareness programme. The outcome of the study was achieved by condensing the themes that emerged in both the primary and secondary data. The framework was then explained as a way of recommending the importance of preparing information security awareness and training programmes in changing information security behaviour. The derived artefact of this study is an information security awareness framework that can be utilised in a provincial government department to increase the awareness of information security amongst government employees. The contribution of this study is a framework based on the Protection Motivation Theory and the Organisational Culture, to ascertain employees’ actions in relation to information risks and threats; requirements for preparing an information security awareness program for public sector employees and to determine the requirements to be considered when building information security culture in provincial government departments. The proposed framework can then be used to establish an information security culture within the government departments, which will mitigate security risks and threats. The significance of this study as per the constructs of ISA and training show that it can challenge thinking of how ISA can be prepared for not only provincial government but also for state-owned entities or local government. , Thesis (MCom) (Information Systems) -- University of Fort Hare, 2022

- Description: A Smart Home Control System can provide a secure home, convenience, comfort, and interactivity of life in a particular home. The system can enable the automatic controlling of a house via a Smart Phone. These systems are becoming vital and widely used in homes to improve conditions of life. Most commercial home automation systems are expensive and their maintenance would require experts who understand the underlying implementation of the systems. This study developed a mobile-based home automation system prototype. The system was developed using the waterfall model methodology. To evaluate the developed system, the study used a simulation method. Ten trials were conducted to determine the performance of the implemented system. The mean time to failure was used to evaluate the system’ reliability. The system’s performance analysis revealed that the developed system performed better than the two other approaches; the Bluetooth and ZigBee. The developed system showed a 0 percent error, while the Bluetooth had 8 percent error and ZigBee 6 percent error. The reliability results showed the average lifespan of assets in the system before they could fail. Knowing the lifespan of an asset before it fails can help in reducing downtime of the system by planning or scheduling maintenance and develop an improved maintenance strategy. , Thesis (MSc) -- Faculty of Science and Agriculture, 2021

- Description: Background: The development of antimicrobial resistance (AMR) has been linked to the increased and irrational use of antimicrobial medicines. The aim of this study was to investigate the antimicrobial prescribing practices in the paediatric medical ward at Mahalapye District Hospital (MDH) in Botswana and to determine whether antimicrobial stewardship (AMS) measures were being implemented at the hospital. Methods A cross-sectional, descriptive, mixed methods, observational approach was taken in this study. The study site was the paediatric medical ward (PMW) at MDH. Information about the antimicrobials prescribed for paediatric patients from January 2018 to December 2018 was collected from patients’ information files and compared to national antimicrobial prescribing guidelines to determine prescribers’ adherence. Qualitative semi-structured interviews were conducted with members of staff at MDH to determine whether antimicrobial stewardship (AMS) measures were adopted at the hospital. Results A total of 278 patients were included in this study, 12 of these were admitted twice during the study period. In total 290 admissions were analysed, with 659 antimicrobial medicines prescribed. The most common diagnoses were pneumonia (36.9%), acute gastroenteritis (20.7%), upper respiratory tract infections (3.4%), and bronchiolitis (3.1%). The most prescribed antimicrobials were ampicillin (21.4%), gentamicin (21.2%), and cefotaxime (8.3%). Adherence to guidelines was relatively good, with 82.7% of antimicrobials prescribed for the patients in the study having been prescribed in compliance with the national prescribing guidelines. The semi-structured interviews highlighted the fact that staff knew about AMS and AMR in general, however awareness of an AMS committee at MDH varied. The AMS committee was a multidisciplinary committee, which was a subcommittee of the Drugs and Therapeutics Committee (DTC). Discussion and Conclusion The results suggest that adherence to prescribing guidelines was relatively high compared to other paediatric antimicrobial utilisation studies in African countries. Prescribing of antimicrobial medicines was consistent with other African countries. The long period of time that it takes for microbiological test results to become available means that most prescribers rely on empirical prescribing. The antimicrobial committee is a multidisciplinary committee with defined roles for its members, consistent with international guidelines for implementing an AMS committee at a hospital. , Thesis (MPharm) -- Faculty of Pharmacy, Pharmacy, 2022

- Description: Preventive and curative eye-care services are a critical component of care for patients diagnosed with chronic diseases. The South African constitution guarantees health as a fundamental human right of all citizens. While most chronically ill patients are managed at the primary health care centers, eye care services are currently contracted to private service providers. The extent to which people, especially the chronically ill patients, have access to eye-care service under the current structure is less understood. The study aims to establish the effectiveness and sustainability of the eye-care service delivery model at the Michael Mapongwane CHC, with specific reference to access to eye-care services. Specifically, the study examined the rate and determinants of eye-care service utilisation, assess user’s satisfaction and perspectives of primary health workers and private service providers regarding the current structure of eye-care services. The study adopted a descriptive and explanatory design, which involved a survey and semi-structured interviews. The survey was conducted among 423 patients attending the two primary health centers selected for this study. Patients with chronic illness were recruited over a period of one month. Overall, 365 patients with chronic illness and 58 patients without chronic illness took part in the study. Descriptive and inferential statistics were used to analyse the quantitative date. Purposive sampling was used to select nine health workers and 10 private eye-care service providers for the semi-structured interviews. The data obtained were transcribed and coded. Thematic content analysis was performed on the qualitative data. The results show that less than half of the respondents (n=168) had ever had an eye test, and an even lower proportion (n=115) had had an eye test in the past two years. Age, female sex, formal rural dwelling, marital status, and income were significantly associated with ever having an eye test done. The results reveal a gross inequality in access to eye care test. Only 19.2% of patients diagnosed with hypertension had had their eyes examined. Even fewer proportions of the patients (8.5%) had had their eyes examined during or after diagnosis for hypertension. Likewise, only one in three patients diagnosed with diabetes has had their eyes examined before or after they were diagnosed with diabetes. The majority of patients who had used the services affirmed that it was easy to access eye care services. While most respondents agreed that waiting time to make an appointment was not too long, over half of them affirmed that waiting to see an eye doctor was too long. Most users were reasonably satisfied with the eye care services received. Primary health care providers highlighted challenges such as work overload, poor infrastructure, and patient’s forgetfulness of the appointment dates as factors affecting access to eye care services in their clinic. The primary challenges the private eye-care service providers experienced were small rooms or inappropriate clinic rooms, language barrier and inadequate support from the clinics. In conclusion, this study has shown that access to preventive and curative health care services was among patients attending primary health care centres, and especially those with chronic illness. The current structure of eye care services makes it difficult for patients to access care and for providers to provide quality care. , Thesis (MPH) -- Faculty of Health Sciences, 2022

- Description: Since the dawn of democracy in 1994, the government of the Republic of South Africa (RSA) has launched numerous development programmes. These include youth empowerment initiatives aimed at developing the capacity of the youth in order for them to contribute to the economy. Optimistic prospects for any country depend on developing its young people. The measures to drive youth-focused delivery and to ensure youth development ought to move further than the establishment of structures and the delivering of policy statements. Government departments and municipalities are expected to implement meaningful youth empowerment programmes and ventures that are visible and that are adequately monitored. This study explored and assessed the effects of the Expanded Public Works Programme (EPWP) on youth empowerment. It used a case study of Amathole District in the Eastern Cape, South Africa province. The study utilised the qualitative technique to provide solutions to the research problem and to provide responses to the research hypothesis of the study. The sample comprised ten public representatives and thirty youth beneficiaries. In line with the purposive sampling approach, two sets of data were generated: the first set from public managers of the programme, and the second from programme beneficiaries. The researcher made use of the qualitative thematic content analysis approach, where data was analysed to arrive at emerging themes. The study was delimited to the effects of EPWP on youth empowerment. It was also limited to Amathole District within the Eastern Cape province. The results showed that most of the beneficiaries were engaged on a period of 1 to 12 months. This shows that most of participants were not engaged for viable and long periods, which they would need to truly increase their financial or monetary position in their households and have ample time to attain expertise. The results further indicated that in some cases the EPWP provides financial and income support to beneficiaries, but in some it does not. In general, the results showed that the EPWP reduces poverty because participants are able to look after their families and relatives after taking part in the EPWP. However, the training and skills participants attained in the EPWP interventions did not help them find employment elsewhere. This is linked to the findings that showed that beneficiaries were not provided with training certificates. Therefore, to enhance the execution of the EPWP and speed up poverty reduction, equity and joblessness in South Africa, the study recommends that ECDPW in ADM Area should design projects/programmes that are attractive to youth and that will equip them with necessary skills to empower youth to participant in the job market after the leave the programme. Furthermore, the study also recommends that the ECDPW in ADM Area consider public private partnership (PPP) for additional funding for the provision of adequate personal protective equipment (PPE) and training to participants. , Thesis (MPA) -- University of Fort Hare, 2022

- Description: Globally, concern have been raised against the quality of teaching and learning driven by international institution such as the United Nations Educational, Scientific and Cultural Organization and agenda of the Education for All policy. In South Africa, the QTL in secondary school remains low and compromised despite the implementation of EFA policy and use of EDOs in South Africa generally and King Williams Town (KWT) in particular. The drive of this study is to assess the role played by EDOs in supporting QTL in selected secondary schools in King Williams Town District. The study used a qualitative approach, a case study design was followed and the case in point for this study is EDOs in KWT district. Their roles where assessed between two secondary schools namely Enoch Sontonga high school and Nosizwe high school. Ten (10) interviews using face-to face and telephonic method. The study managed to conduct five face-to-face interviews among EDOs as they were conveniently located during a period of workshops in the circuit and two educators and three principals were interviewed electronically. Purposive and convenience sampling techniques were used to select participants. Using the Popper’s theory of learning perspective the study found out that quality teaching and learning in KWT schools is dependent on factors such as time on task, scope of learning, learning environment, teaching methods and strategies, support and monitoring programmes, the teacher preparedness and their motivation and availability of attractive incentives to retain quality practitioners in their classrooms. The study found out that presently the EDOs are performing various roles such as offering support to the SMT through helping them understand their function within the school and the broader education system and helping in developing systems for monitoring and recording progress made by learners towards achievement of targets set. However, there are challenges encountered by EDOs when supporting schools to improve the QTL that were discussed namely, lack of human resources and material resources; educator resistance; non-academic activities; learner and teacher absenteeism; programmes alignment; and work overload. These challenges can be addressed using strategies such as human resources training and recruitment; programmes coordination and stakeholder cooperation; transport provision; consequence management; attitude change and policy alignment and implementation. The study recommends investment in leadership, Monitoring and evaluation, stakeholder engagement and training. , Thesis (MPA) -- University of Fort Hare, 2022

- Description: Globally, concern have been raised against the quality of teaching and learning driven by international institution such as the United Nations Educational, Scientific and Cultural Organization and agenda of the Education for All policy. In South Africa, the QTL in secondary school remains low and compromised despite the implementation of EFA policy and use of EDOs in South Africa generally and King Williams Town (KWT) in particular. The drive of this study is to assess the role played by EDOs in supporting QTL in selected secondary schools in King Williams Town District. The study used a qualitative approach, a case study design was followed and the case in point for this study is EDOs in KWT district. Their roles where assessed between two secondary schools namely Enoch Sontonga high school and Nosizwe high school. Ten (10) interviews using face-to face and telephonic method. The study managed to conduct five face-to-face interviews among EDOs as they were conveniently located during a period of workshops in the circuit and two educators and three principals were interviewed electronically. Purposive and convenience sampling techniques were used to select participants. Using the Popper’s theory of learning perspective the study found out that quality teaching and learning in KWT schools is dependent on factors such as time on task, scope of learning, learning environment, teaching methods and strategies, support and monitoring programmes, the teacher preparedness and their motivation and availability of attractive incentives to retain quality practitioners in their classrooms. The study found out that presently the EDOs are performing various roles such as offering support to the SMT through helping them understand their function within the school and the broader education system and helping in developing systems for monitoring and recording progress made by learners towards achievement of targets set. However, there are challenges encountered by EDOs when supporting schools to improve the QTL that were discussed namely, lack of human resources and material resources; educator resistance; non-academic activities; learner and teacher absenteeism; programmes alignment; and work overload. These challenges can be addressed using strategies such as human resources training and recruitment; programmes coordination and stakeholder cooperation; transport provision; consequence management; attitude change and policy alignment and implementation.

- Description: Better access to high-quality and relevant skills development is essential if South Africa is to achieve its National Development Plan (NDP) 2030 goals. The importance of training opportunities in promoting competence cannot be overstated. Equipping the workforce with the skills needed is a strategic priority for all developing countries’ national growth and progress. This paper seeks to investigate a nexus between employee skills development and competence in the Eastern Cape Department of Education (ECDoE). The paper employed a qualitative research technique and the explanatory research design to achieve its desired objectives. The results of the paper confirmed that skills training and development strategy, when implemented by institutions, ensures that staff is empowered, informed, and taught, which results in better efficiency and effectiveness. In this situation, spin-offs will benefit public organizations since employees’ increased abilities open new opportunities for long-term employment growth and organizational effectiveness. Furthermore, the knowledgeable and well-trained individual would make sound organizational decisions while successfully listening to the clients' problems. The benefits will flow down to the areas where these organizations are headquartered, and the improved image will be the goal for the ECDoE. The conclusion drawn is that Skills Development Act aims to provide skills to the South African workforce, ensure that employees have more opportunities for skill acquisition, provide opportunities for new entrants to gain work experience. The ECDoE should invest more in skills development to increase the competencies of its employees. This will guarantee the achievement of its aims and objectives, through competent employees. , Thesis (MPA) -- University of Fort Hare, 2021

- Description: In developing countries, including South Africa, breast cancer is the primary cause of cancer-related deaths among women. TNBC (triple-negative breast cancer) is an aggressive breast cancer subtype that is more prevalent in women of African descent. This subtype lacks the key receptors, namely the estrogen receptor (ER-), progesterone receptor (PR-), and human epidermal growth factor receptor 2 (HER2-) that are the basis of successful targeted therapies for other subtypes of the disease. To date, there are no effective, standardized targeted therapies for TNBC. Artemisinin is an anti-malarial drug and numerous derivatives of the compound have been developed to improve the potency and solubility of the parent compound. Artemisinin and its derivatives have gained attention as potential anti-cancer agents; however, such studies have not yet progressed to clinical trials and the precise mechanism of action of these compounds is yet to be fully explained. In this study, artemisinin, and its known derivative artesunate, as well as a novel derivative, WHN11, were investigated as DNA damage-inducing agents in TNBC. WHN11 was found to be the most potent of the three compounds, displaying an IC50 of 3.20 μM against HCC70 cells, artemisinin displayed an IC50 of 214.70 μM and artesunate displayed an IC50 of 25.48 μM. The compounds were less toxic to the MCF12A non-cancerous cells, with IC50 values 298.30, 87.53, and 8.35 μM for artemisinin, artesunate, and WHN11, respectively, and displayed selectivity indices of 1.39, 3.44 and 2.61 μM for artemisinin, artesunate, and WHN11, respectively. In silico and in vitro studies revealed that the artemisinin compounds bind to DNA through the minor groove. While all three compounds were able to bind to DNA, a comet assay revealed that only artemisinin and artesunate, and not WHN11, were able to cause DNA damage compared to the vehicle control, DMSO. Finally, a topoisomerase I (TOPO I) enzyme assay demonstrated that while the compounds appeared to display a degree of inhibition of TOPO I, as evidenced by a downward shift in the plasmid band on the agarose gel, they were not able to fully inhibit the enzyme to return the plasmid to the supercoiled conformation. In addition, combination studies revealed that artemisinin, artesunate, and WHN11 acted synergistically in combination with camptothecin, but displayed either an additive (artemisinin) or antagonistic (artesunate and WHN11) relationship when used in combination with etoposide. In conclusion, artemisinin, its known derivative artesunate, and novel and highly toxic derivative WHN11, all bind to DNA via the minor groove, however only artemisinin and artesunate, and not WHN11, cause DNA damage, indicating a potentially different mechanism of action of the three artemisinins. All three compounds act synergistically with camptothecin, which suggests interference with topoisomerase activity, partially supported by slight inhibition of TOPO I activity, and could indicate either direct inhibition of the enzyme or interference with enzyme function by competitive binding to the DNA. Further studies could help explore alternate DNA damage assays, to validate these findings, and the effect of the compounds on TOPO II activity could also be assessed. , Thesis (MSc) -- Faculty of Science, Biochemistry and Microbiology, 2022

- Description: This research centres on the holistic assessments of spatial and temporal dimensions of soil erosion zones based on the parameters of geomorphometry, hydro-statistics, and land use/cover dynamics. The study used a case study approach based on a clustered framework model of soil erosion parameters in the Tyume River basin in Eastern Cape, South Africa. The methods adopted for the investigation are, namely; non-parametric time-series assessment of streamflow dataset, semidecadal assessment of land use/cover (LU/C) dynamics, geospatial analysis of geomorphometric variables, vulnerability analysis of soil erosion zones, regression analysis of determination coefficient, and Receiver Operating Characteristic Curve (ROC). The delineation of soil erosion zones was based on the integrated analysis of the parameters of geomorphometry, geology, hydrology, and land use/ cover. The result of the hydro-statistical analysis of the Tyume River reports a major decline in the inter-annual regime frequency of storm flow based on the Mann- Kendall (MK) test and Sen’s slope assessment in 1992 (p-value = 0.031), 1997 (p-value = 0.045), 2003 (p-value = 0.021), 2008 (p-value = 0.003), and 2016 (p-value = 0.002). The MK test depicted a recurrence of peak streamflow acceleration in every three years based on low-flow and highflow transition. The sensitivity of LU/C to temporal dynamics of streamflow trends shown by the coefficient of correlation of trends of the LU/C water bodies with streamflow semi-decadal acceleration indicates a moderately relevant relationship, R = 0.76. The temporal analysis of LU/C and hydro-statistical analysis shows that the Tyume basin was highly vulnerable to soil erosion by water in 1999, 2009, and 2019. The vulnerability of the Tyume River basin in 2019 is exceptional and this is due to the conversion of forested area (woodland) into a built-up environment and farmland, with a high vulnerability in 2019 due to the slump in the rate of change of woodland and precipitation, and the increase in the rate of built-up and agricultural activities. The soil erosion vulnerability mapping divides the river basin into the critical high, high, moderate, low, nonvulnerable zones that cover 40 km2, 135 km2, 209 km2, and 186 km2 respectively. Regression analysis shows that the areas of soil erosion in the Tyume basin are moderately represented by the model (R2 = 56) while the model performance assessment based on success rate and prediction rate estimation from the area under the ROC curve shows that the model is good, Area Under Curve of the ROC = 0.899, and 0.897. The analysis suggests that soil erosion is driven by the impact of land use/land cover change, particularly in areas of high drainage density. Significantly, high vegetation density played a vital role in lowering high-flow on the hill-slope and low topographic wetness area as well as in areas with erodible geologic properties. The study, therefore, recommends the advocacy of crop rotation method of agricultural practice in the highly critical areas of soil erosion and recommends the development of riparian forests around the Tyume River. The study provides important information for environmental stakeholders on degradable areas which may require the urgent implementation of sustainable development measures. , Thesis (MPhil) -- Faculty of Science and Agriculture, 2022

- Description: With South Africa's long history of colonialism and racial oppression, there are still services in the country that many South Africans cannot relate to, including psychology. Research shows that many South Africans experience and are affected by mental distress due to several factors, including poverty, unemployment, and traumatic experiences. Managing and treating such distress has always been challenging for most South Africans. Some debates question the relevance of psychological services from the West in a South African context. This study explores other approaches to psychology that look beyond the Biopsychosocial model when dealing with certain types of disorders in an African context. African psychology, or the Afrocentric approach, looks at what is beneath the surface, not just the presenting problem. Mainstream psychology strives to be universal and applicable to all. However, African psychology disagrees with this notion. African psychology perceives human beings as strongly influenced by social and cultural influences. The focus of this approach includes the spiritual realm and the attached meanings. There is evidence for the need to merge Traditional and Western medicine. The research methodology for this study is qualitative, using Interpretative Phenomenological Analysis. IPA allows for a critical engagement with the ways in which participants construct their reality. The researcher carried out semi-structured interviews to enable participants, all traditional healers (3 female and 2 male), to narrate their experiences dealing with mentally distressed clients. The accounts of these traditional healers were analysed focusing on people who have experienced mental distress. From the analysis and synthesis of the themes, findings illustrate how traditional healers conceptualise and construct mental distress from an African Psychology paradigm. An emerging core theme was the importance of the divine call and its influence on the chosen treatments. More studies are needed to illustrate the potential for collaboration between African Traditional healing and EuroAmerican healing practices, to provide holistic services to people in need. , Thesis (MA) -- Faculty of Humanities, Psychology, 2022

- Description: Hepatitis B infection is a deadly infectious disease caused by the hepatitis B virus and is responsible for many deaths every year worldwide. Despite medication and vaccines against hepatitis B infection, it still presents high morbidity and mortality among populations. This is partly due to factors such as a long medication period of the existing treatments, resulting in poor patient compliance and leading to treatment failure. In addition, this situation can be responsible for the observed emerging drug resistance. Hence, novel drugs and drug delivery systems are needed to tackle this matter. Many strategies have been used to develop long-acting drug delivery systems treatment for several infectious diseases. Hydrogel drug delivery systems have shown interesting results as controlled drug delivery systems for several drugs. Therefore, the present study aimed to develop chitosan grafted poly (acrylamide-co-acrylic acid) hydrogel and apply it as a pH-sensitive controlled delivery system of tenofovir disoproxil fumarate (TDF). TDF is a nucleoside reverse transcriptase inhibitor used as first-line treatment of hepatitis B chronic infection and in the treatment of other viral infections. The free-radical polymerization method was utilized to modify chitosan by grafting acrylamide and acrylic acid and using N, N’-methylene bisacrylamide as the crosslinking agent to prepare the hydrogel, followed by an optimization of parameters that could affect the swelling capacity. The prepared chitosan-g-poly(acrylamide-co-acrylic acid) hydrogel was characterized using Fourier Transmission Infra-red spectroscopy (FTIR), X-Ray Diffraction (XRD), Thermal Gravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC), Energy-dispersive X-ray spectroscopy (EDS), Scanning Electron Microscopy (SEM), and was evaluated for cytotoxicity using a HeLa cell assay. TDF was used as a drug model, it was loaded by the swelling equilibrium method, following by the investigation of the release profile of TDF-loaded hydrogel at pH 1.2 and 7.4. A successful synthesis of chitosan grafted poly(acrylamide-co-acrylic acid) hydrogel was confirmed by Fourier Transmission Infra-red spectroscopy (FTIR), X-Ray Diffraction Spectroscopy (XRD), Thermal Gravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC), Energy-dispersive X-ray spectroscopy (EDS) and Scanning Electron Microscopy (SEM). Optimization results showed that the ratio of monomers impacted the swelling ratio of the hydrogel and both the concentration of the crosslinking agent, and the reaction initiator also affected the swelling ratio. The synthesized hydrogels were sensitive to pH and ionic strength. Hydrogel swelling was lower in acidic solutions and higher in neutral and basic solutions and decreased with the increasing ionic strength. Furthermore, SEM results revealed that hydrogel have a rough and fibrous surface structure with numerous pores. Cytotoxicity studies demonstrated that the hydrogel was non-cytotoxic at 50 μg/ml against HeLa cells which suggested a good biocompatibility of the material. TDF was loaded and released from the hydrogels and showed an encapsulation efficiency and drug loading percentage ranging from 81-96% and 8-10%, respectively. TDF release profile was found to be low in buffer solution of pH 1.2 (in the range of 5-10%) and much higher (38-53%) at pH 7.4 within 96 hours. TDF maintained its chemical integrity after release and the hydrogels can therefore be proposed as a new controlled-release drug delivery system for hepatitis B treatment. , Thesis (MSc) -- Faculty of Science, Chemistry, 2022

Hydrogel swelling was lower in acidic solutions and higher in neutral and basic solutions and decreased with the increasing ionic strength. Furthermore, SEM results revealed that hydrogel have a rough and fibrous surface structure with numerous pores. Cytotoxicity studies demonstrated that the hydrogel was non-cytotoxic at 50 μg/ml against HeLa cells which suggested a good biocompatibility of the material. TDF was loaded and released from the hydrogels and showed an encapsulation efficiency and drug loading percentage ranging from 81-96% and 8-10%, respectively. TDF release profile was found to be low in buffer solution of pH 1.2 (in the range of 5-10%) and much higher (38-53%) at pH 7.4 within 96 hours. TDF maintained its chemical integrity after release and the hydrogels can therefore be proposed as a new controlled-release drug delivery system for hepatitis B treatment. , Thesis (MSc) -- Faculty of Science, Chemistry, 2022

- Description: The SADC region is a 15-member states grouping. Countries in the region have experienced low growth coupled with high levels of poverty and inequality. Attracting FDI to the region has been top priority. However, much is still to be realised. The study employed the Generalised Method of Moments (GMM) technique for the period 1980 to 2019. Empirical results show that financial sector development and financial openness are important determinants of foreign direct investment (FDI) inflows. The results also showed that institutional quality is also a very important variable in determining the inflow of FDI, even though its effect is conditional on financial sector development and financial openness. These results imply that countries with good institutional framework, as well as a developed financial sector and are financially open tend to attract more capital inflows in the form of FDI, thereby creating adequate conditions to boost private sector and investment abroad. Countries in the SADC region should therefore pursue policies which are aimed at improving the institutional framework, the level of financial sector development and further enhance the openness of their financial openness. , Thesis (MCom,) -- Faculty of Management and Commerce, 2022

- Description: The citrus industry contributes significantly to the South African agricultural sector. Thaumatotibia leucotreta (Meyrick) (Lepidoptera: Tortricidae) is highly important to the South African citrus industry as it is classified as a phytosanitary pest by most international markets. Thaumatotibia leucotreta has caused an estimated annual loss of up to R100 million to the industry. In order to control T. leucotreta in South Africa, an integrated pest management (IPM) programme has been used. One of the components of this programme is Cryptophlebia leucotreta granulovirus (CrleGV), which has been formulated to a registered biopesticide namely Cryptogran and has been successfully applied in the field for over 15 years. To use CrleGV as biopesticides, quantification of the viral particles is required to perform bioassays for field trials and formulation, among other applications. Darkfield microscopy is a traditional method used for the quantification of CrleGV; however, the method is characterised as being subjective, tedious, labour intensive, and time-consuming. This study aims to develop and optimise a qPCR technique to accurately quantify CrleGV-SA OBs using plasmid DNA for downstream applications. Firstly, lef-8, lef-9, and granulin conserved genes from CrleGV-SA and CrleGV-CV3 genome sequences were analysed by performing multiple alignments to evaluate the degree of identity between these genes. This was done to design two sets of oligonucleotides (internal and external) from regions with the highest identity. Subsequently, in silico testing was done to evaluate the designed oligonucleotides to determine whether they specifically bind to the selected target regions. Secondly, three sets of DNA plasmids (pJET1.2-Gran, pJET1.2-lef-9, and pJET1.2-lef-8) were constructed, each containing a target region for either granulin, lef-9, and lef-8 genes for use as standards in a downstream qPCR assay. This was achieved by first extracting gDNA from CrleGV-SA OBs and using the gDNA as a template to PCR amplify the target regions of the selected gene regions with the designed oligonucleotides. Subsequently, the PCR amplified regions were then directly ligated into the pJET1.2/blunt vector, and the plasmids were confirmed by colony PCR, restriction enzyme digestion, and Sanger sequencing. Thirdly, two different methods of CrleGV-SA gDNA extraction were compared to determine which method has the best yields in terms of concentration. The extraction methods compared were the Quick-DNA Miniprep Plus kit according to manufacturer’s instructions (Method 1a), pre-treatment with Na2CO3 prior to using the Quick-DNA Miniprep Plus kit (Method 1b), pre- treatment with Na2CO3, and neutralisation with Tris-HCl prior to gDNA extraction using the Quick-DNA Miniprep Plus kit (Method 1c) and the CTAB method (Method 2). The gDNA concentration and purity for all samples were determined using a Nanodrop spectrophotometer. Method 1c (Na2CO3 and Tris-HCl pre-treated plus Quick-DNA Miniprep Plus kit) was the most efficient at extracting genomic DNA compared with the other methods, resulting in the highest DNA concentration in short processing time. Fourthly, plasmid standards were evaluated for use in the qPCR assay. This was done as it was important to consider the efficacy of the oligonucleotides; including the ability of the oligonucleotides to anneal to the appropriate segment of DNA without extensive formation of oligonucleotides dimers, non-specific annealing, or formation of secondary structure. In addition, it was done to ensure that highly accurate standard curves were generated. The standard curves were to be utilised in the downstream qPCR assay to determine the quantity of test samples by interpolation, reading from the values within the standard curve. Lastly, darkfield microscopy and qPCR methods of enumeration were compared to verify their accuracy and determine the most consistent and comparable method. This was achieved by quantifying the purified, crude-purified, and viral formulated CrleGV-SA suspensions using these methods. Subsequently, a statistical analysis was conducted to compare the results produced by the two enumeration methods. The obtained results showed that the granulin, lef- 8 and lef-9 qPCR values did not significantly differ from the darkfield microscopy results. The findings of this study revealed that the two assays, lef-8 qPCR and lef-9 qPCR, were more robust, sensitive, and efficient for the quantification of CrleGV-SA. Thus, this study has successfully developed a qPCR assay that is comparable with the traditional darkfield microscopy counting technique. This is the first study to use the qPCR technique to enumerate CrleGV-SA using plasmid standards. The developed qPCR assay is reliable, rapid, and cost- effective and has a great potential to be used as an alternative method to darkfield microscopy in the laboratory and commercial settings. , Thesis (MSc) -- Faculty of Science, Biochemistry and Microbiology, 2022

- Description: High school teachers in South Africa have been voicing out their distress to the government, caused by the indiscipline of learners. The indiscipline became evident after the South African government scrapped punitive behaviour modification methods such as corporal punishment. Although the government had introduced alternative forms of behaviour modification, the teachers still maintain that these are not effective hence the rife indiscipline behaviour among high school learners. This study reviewed 14 articles on the impact of the alternative forms of punishment on high school learners’ indiscipline and the teachers’ motivation. Further, the studies highlight several factors involved in developing the learners’ indiscipline. This review indicates that high school learners’ indiscipline continues to be rife in South African schools and negatively affects high school teachers’ motivation. This is regardless of the government's introduction of alternative forms of punishment. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2022

- Description: Monitoring and evaluation have gained popularity due to the rising demand for the public sector to enhance both policy and project outcomes. A rising number of countries are pursuing outcomes orientation by establishing and enhancing their government's monitoring and evaluation system. The researcher discovered that the E.C DEDEAT lacks a thorough mechanism for monitoring and evaluating government performance and the effect of service delivery. As a result, the researcher set out to investigate the implementation of the GWM&E system. The study adopted a qualitative approach. Questionnaires, semi-structured interviews, and document analysis were used to collect data, and a content analysis was adopted to analyze data. The study revealed that South Africa had set various legislative frameworks to support monitoring and evaluation. There is a significant shift from traditional methods of accountability towards public sector monitoring and evaluation. While this is true, the study also found out that monitoring systems are still faced with various challenges within the department. Lastly, the study proffered recommendations on how public sector monitoring and evaluation can be enhanced. , Thesis (MPA) -- University of Fort Hare, 2022

- Description: Climate is an important factor in agricultural production. The world is facing climate change and variability, which result in high temperatures, low rainfall patterns, shortage of water and persistent droughts. Climate change poses a significant threat to South Africa’s water resources, food security, health, infrastructure, ecosystem services and biodiversity. Negative impacts of climate variability on agriculture, especially on maize the staple crop, will worsen the food security status of the nation as most of South Africa’s maize crop is produced in summer and highly depends on rainfall. This study attempted to assess the impact of climate on maize production in South Africa using secondary time series data for the period 1937 to 2018. Rainfall and temperature were used as proxies for climate variability. The Granger Causality Model was used to examine the causal linkages between climatic variables (temperature or rainfall) and maize output in South Africa for the study period. The major outcome of the analysis was that there is a two-way causal relationship between maize production and temperature. The results also indicated that there is uni-directional causality between maize yield and rainfall. Furthermore, the Variance Decomposition Model was used to forecast the relationship between climatic elements and maize production in South Africa. The result showed that all variables have an effect on maize yield, with temperature having the least effect. The last objective of the study was to profile the maize output trend for the period from 1937 to 2018. The main findings from the analysis indicate that maize production in South Africa has a general upward slope. The study recommends that the government should intensify the provision of irrigation systems for the farmers in the most vulnerable areas to mitigate the climate change. Government should also embark on massive campaigns using a variety of media to create the needed public awareness on climate change and its impact on food security. , Thesis (MSc) -- Faculty of Science and Agriculture, 2022

- Description: Due to the disabling effects of severe labour pains, labour pain management remains an important topic in midwifery and needs to be reviewed more often. According to studies, various pain relief options, both pharmacological and non-pharmacological, are available to help women cope with pain, but midwives did not employ these techniques adequately because of various experiences. Studies further indicate that, though the limited number of these techniques were employed they were not effective on some women. Thus, the purpose of this research study was to explore and describe midwives’ experiences on pharmacological and non-pharmacological labour pain management in the Lejweleputswa District of the Free State Province. This study employed a qualitative, descriptive, explorative, and contextual design. A purposive sampling technique was used to select the participants. The target population was midwives who work in the maternity wards of the institutions under study with three to five years’ experience in midwifery. Individual, face-face, semi-structured interviews were conducted; these were recorded for the researcher’s reference purposes, so as not to overlook important information. In addition, the researcher made use of field notes, recording in them what was heard, observed, felt, experienced, and thought during the interview. Ethical principles and trustworthiness were maintained throughout this study. Data analysis was done using Tesch’s approach to open coding in qualitative research. Confidentiality and anonymity were ensured throughout the interviews. The nine themes and 19 sub-themes that emerged during data analysis were discussed comprehensively. The findings indicate that midwives use both pharmacological and non-pharmacological methods in managing labour pain. Some methods are effective in relieving pain for certain mothers, while other methods proved ineffective. Midwives administer Pethidine and Phenergan as per doctors’ prescription; non-pharmacological methods, such as back massage, deep breathing exercises, mobilisation, and warm baths or showers are also employed. Midwives provide pharmacological methods to all women in labour, and routinely employ non- pharmacological methods. Although the midwives are willing to manage patients’ pain, they face certain challenges, such as shortage of staff, increased workload, as well as inadequate resources. This leads to inadequate provision of non-pharmacological care. In conclusion, the midwives’ experiences were that both pharmacological and non-pharmacological techniques were used for all labouring women and they had relaxing and calming effects on some women, resulting to them giving birth with ease, although for some they were not effective. In addition, the pharmacological interventions caused drowsiness to some women and babies. The findings will provide evidence-based information to the Free State Department of Health in order to assist policymakers and stakeholders in initiating and developing appropriate policies, guidelines, and interventions that can improve labour pain management. The Free State Department of Health should consider using other opioids and non-opioids in managing labour pain to broaden the scope of pain relief methods available to the midwives. , Thesis (MPH) -- Faculty of Health Sciences, 2022

Midwives administer Pethidine and Phenergan as per doctors’ prescription; non-pharmacological methods, such as back massage, deep breathing exercises, mobilisation, and warm baths or showers are also employed. Midwives provide pharmacological methods to all women in labour, and routinely employ non- pharmacological methods. Although the midwives are willing to manage patients’ pain, they face certain challenges, such as shortage of staff, increased workload, as well as inadequate resources. This leads to inadequate provision of non-pharmacological care. In conclusion, the midwives’ experiences were that both pharmacological and non-pharmacological techniques were used for all labouring women and they had relaxing and calming effects on some women, resulting to them giving birth with ease, although for some they were not effective. In addition, the pharmacological interventions caused drowsiness to some women and babies. The findings will provide evidence-based information to the Free State Department of Health in order to assist policymakers and stakeholders in initiating and developing appropriate policies, guidelines, and interventions that can improve labour pain management. The Free State Department of Health should consider using other opioids and non-opioids in managing labour pain to broaden the scope of pain relief methods available to the midwives. , Thesis (MPH) -- Faculty of Health Sciences, 2022

- Description: Medical male circumcision has been shown to reduce female to male HIV transmission. This study was designed to examine the underlying factors responsible for, or influencing, the inability of the health care system to achieve the MMC targets in selected hospitals in KZN. The objective of this study to was explore the challenges that lead to failure of the government to meet set targets, regarding the implementation of the MMC programme in the province of KZN, as perceived by the health care workers. Methodology A mixed quantitative and qualitative study where 150 questionnaires were used and in-depth open-ended interviews were conducted. Participants were from Clairwood and Wentworth hospitals in the district of eThekwini, KwaZulu-Natal. Eighteen healthcare workers (nurse managers, doctors, nurses and counsellors) were purposively selected from the two hospitals. Results Findings showed that poor marketing of MMC, in line with the cultural and religious inclination of the catchment populations, had an effect on the targets. The fear of pain by the male clients came out as the biggest factor followed by the fear of having an HIV test done. The six weeks healing period before indulgence in sexual intercourse had a part to play in the reluctance of clients to do MMC. Some clients feared losing the ability to have an erection post MMC and would therefore not come for MMC. Other contributory factors for failure to reach targets included shortage of staff, poor mobilisation by the staff due to lack of training on how to mobilise and how to market MMC, lack of availability of mobilisation and marketing resources, inadequate and inequitable allocated of resources. Other factors include, lack of incentives for staff to stay in the programme or even within the Department, lack of training, cultural and religious beliefs in the community. The staff also felt that the MMC targets were too high. Notwithstanding, the staff members were willing to learn how to market MMC and to mobilise clients. Clients and community education on the importance of MMC and the combination of this process with good sexual behaviour would improve MMC uptake and reduce HIV prevalence and the incidence. Conclusions The fear of pain, fear to do HIV test and the fear to loose erection were the most prominent reasons why the males would not come for MMC procedure. , Thesis (MPH) -- Faculty of Health Sciences, Public Health, 2022
