- Description: Evaluation of resistant profiles and detection of antimicrobial-resistant genes of bacterial pathogens in the nonclinical milieu is imperative to assess the probable risk of dissemination of resistant genes in the environment. .is paper sought to identify antibiotic-resistant genes in Pseudomonas aeruginosa from nonclinical sources in Mthatha, Eastern Cape, and evaluate its public health implications. Samples collected from abattoir wastewater and aquatic environment were processed by membrane filtration and cultured on CHROMagarTM Pseudomonas medium. Species identification was performed by autoSCAN-4 (Dade Behring Inc., IL). Molecular characterization of the isolates was confirmed using real-time polymerase chain reaction (rPCR) and selected isolates were further screened for the possibility of harboring antimicrobial resistance genes. Fifty-one Pseudomonas species were recovered from abattoir wastewater and surface water samples, out of which thirty-six strains were Pseudomonas aeruginosa (70.6%). .e P. aeruginosa isolates demonstrated resistance to aztreonam (86.1%), ceftazidime (63.9%), piperacillin (58.3%), cefepime (55.6%), imipenem (50%), piperacillin/tazobactam (47.2%), meropenem (41.7%), and levofloxacin (30.6%). Twenty out of thirty-six P. aeruginosa displayed multidrug resistance profiles and were classified as multidrug-resistant (MDR) (55.6%). Most of the bacterial isolates exhibited a high Multiple Antibiotic Resistance (MAR) Index ranging from 0.08 to 0.69 with a mean MAR index of 0.38. In the rPCR analysis of fifteen P. aeruginosa isolates, 14 isolates (93.3%) were detected harboring blaSHV, six isolates (40%) harbored blaTEM, and three isolates (20%) harbored blaCTX-M, being the least occurring ESBL. Results of the current study revealed that P. aeruginosa isolates recovered from nonclinical milieu are resistant to frontline clinically relevant antipseudomonal drugs. .is is concerning as it poses a risk to the environment and constitutes a public health threat. Given the public health relevance, the paper recommends monitoring of multidrug-resistant pathogens in effluent environments.

- Description: ABSTRACT. This study described anatomical, histological and histochemical features of the mucosal layer of the digestive tract of Tilapia sparrmanii Smith, 1840, an omnivorous freshwater fish endemic to Southern Africa. This species exhibited a short thick oesophagus with long deep longitudinal folds (466.68 ± 16.91 µm), and a thick (173.50 ± 10.92 µm) muscular layer that allow the passage of large food items. The mucosa was lined with stratified secretory epithelium rich in goblet cells that secreted neutral and acid mucins. The stomach was a sac-like structure with simple tubular glands surrounded by connective tissue. The mucosa was lined with simple columnar epithelium and the lamina propria exhibited a well-developed layer of gastric glands that occupied the entire length of the cardio-fundic region. The stomach mucosa consisted of epithelial cells with intense neutral mucin secretion which protects against gastric juice. Neck cells of gastric glands synthesized neutral and acid mucins. The intestine was highly coiled and presented a complex pattern of transversal folds internally (villi). Villi length decreased progressively from the anterior to the posterior intestine (p < 0.0001). Tunica muscularis of the mid-intestine had the thinnest thickness among all parts of the intestine (p < 0.0001). Goblet cells whose numbers increased towards the rectum secreted both acid and neutral mucins. The results indicate structural similarities of T. sparrmanii GIT with other tilapia species and will be useful for understanding the physiology of the digestive systems as well as functional components of the GIT.

- Description: Background: Insufficient iodine intake in pregnancy is associated with many adverse pregnancy outcomes. About 90% of African countries are at risk of iodine deficiency due to poor soils and dietary goitrogens. Pregnancy predisposes to insufficient iodine nutrition secondary to increased physiological demand and increased renal loss. Iodine deficiency is re-emerging in countries thought to be replete with pregnant women being the most affected. This review seeks to identify the degree of iodine nutrition in pregnancy on the entire African continent before and after the implementation of national iodization programmes. Methods: A systematic search of published literature will be conducted for observational studies that directly determined the prevalence of insufficient iodine intake among pregnant women in Africa. Electronic databases and grey literature will be searched for baseline data before the implementation of population-based iodine supplementation and for follow-up data up to December 2018. Screening of identified articles and data extraction will be conducted independently by two investigators. Risk of bias and methodological quality of the included studies will be assessed using a risk of bias tool. Appropriate meta-analytic techniques will be used to pool prevalence estimates from studies with similar features, overall and by major characteristics including the region of the study, time period (before and after implementation of iodization programmes), sample size and age. Heterogeneity of the estimates across studies will be quantified and publication bias investigated. This protocol is reported according to Preferred Reporting Items for Systematic reviews and Meta-Analysis protocols (PRISMA-P) 2015 guidelines. Discussion This review will help ascertain the impact of national iodization programmes on the iodine nutrition status in pregnancy in Africa and advise policy on the necessity for monitoring and mitigating iodine deficiency in pregnancy in Africa. This review is part of a thesis that will be submitted to the Faculty of Health Sciences, University of Cape Town, for the award of a PhD in Medicine whose protocol has been granted ethics approval (UCT HREC 135/2018). In addition, the results will be published in a peer-reviewed journal.

- Description: This conceptual paper aimed to explore the transformation of university libraries in South Africa into dynamic learning spaces that cater to evolving academic and social needs of students. In the context of South Africa's rapidly changing higher education landscape, where inclusivity and technological advancements are paramount, the role of university libraries is shifting from traditional information repositories to hubs of collaborative learning and student engagement. The paper employed a qualitative review of literature and an analysis of the existing infrastructures in libraries of Historically Disadvantaged Institutions (HDIs) to identify strategies for this transformation. The findings highlighted the pivotal role libraries play in promoting lifelong learning, enhancing digital literacy, and supporting academic success. Key recommendations include the integration of advanced technology, the creation of flexible, student-centred spaces, and the incorporation of inclusive practices to accommodate diverse student populations. This paper contributes to ongoing research by offering a model for reimagining library spaces in line with global trends, providing insights for other educational institutions seeking to foster dynamic, student-focused learning environments.

- Description: Rhodes University Honorary Doctorate Citation (5 April 2024) Tandabantu Tennyson August: 1980s. South Africa. In the Bantustans of the time, like the Transkei, the youth have little reason for hope. They have much reason for despair. Their choices seem limited to the politics of struggle or to crime, an attempt to gain some kind of advantage from the meagre and unacceptable options on offer. In those bleak times, what was needed was visionaries. People who could see beyond the current circumstances to a different future and imagine how best to prepare for it. Not as idealists, but as pragmatists. What would happen once circumstances change, once the struggle had succeeded? Would we be ready for it? What qualities would the youth need to have in order to both benefit from and participate in a new dispensation? One such visionary was Tandabantu Tennyson August, and it is my distinct pleasure to have the opportunity to tell you more about him. Born in 1948, Mr. August matriculated from Healdtown High School, before pursuing higher education at the University of Transkei, where obtained a Bachelor of Arts degree majoring in English and Geography. This was followed by Comparative Curriculum Studies at the University of South Africa, alongside obtaining teaching certificates from Lovedale and Cicira teacher training colleges, with majors in Physical Science, Mathematics, Science, and Mathematics. This solid educational foundation laid the groundwork for his impactful career in education. He taught at Wongalethu High, St Johns College and was deputy principal at Norwood, before taking up his first principalship, at Thanga High School in 1980. From 1984 to 1990 he was principal of Ndamase High School. During his tenure there, the matric pass rate never fell below 90%. From 1991 to 1995 he was principal Isivivane High School during which time the school was promoted from a primary to a high school. Following his distinguished service at schools, he worked at the Eastern Cape Department of Basic Education, first as a deputy chief education specialist (1996 – 2006) and then as chief education specialist (2006-2010). During that time, he played a pivotal role in establishing (in conjunction with Rhodes University) and being the provincial coordinator the Advanced Certificate in Education in English, followed by ACEs in mathematical literacy and life orientation. In 2016 he received a provincial teaching award for excellence. In 2017 he was awarded the Kade Asmal award for excellence in teaching. To this day, he remains an Executive member of the eastern cape Education advisory council. Quite a career. But there’s something I haven’t mentioned. He was also an accomplished rugby player of international standing. While at Lovedale College, he was selected to represent Border and then the South African African Rugby Board, playing England in Gqeberha in 1972, in a team that would later be known as the black springboks. He eventually received his green and gold springbok blazer as just recognition of his achievement. He incorporated his love of sport into his vision for the youth under his care, as part of his overriding mission of educating the whole person. He got everyone involved in sport, if not as a player, then as a supporter. Especially during his time as principal of Ndamase High School, I am led to believe, it was extremely intimidating for opposing teams to play them. Not only at Ndamase home games, but especially at their away games. There would be one bus for the team players, and six buses for the supporters. From 1986 – 1990: he was president of the Transkei schools` sports union (TSSU). But there’s yet another thing I haven’t mentioned. In 1981, just as his career as an educational leader was really taking off, he was involved in a terrible motor vehicle accident. It left him permanently disabled and, for much of his life, a wheelchair user. Rather than stopping him, it simply added another string to his bow, now as an advocate for the disabled. From 2012 – 2022: Chairperson Eastern Cape South African National Association For Special Education (SANASE): this organization cater for the education and wellbeing of learners with disabilities and special needs. In 2023, he was the national deputy president of the same organisation. From 2013 – to date: he is a Board Member on the National Council of & for persons with disabilities (NCPD). I had the pleasure of an extensive conversation with one of Mr August’s former pupils at Ndamase High, Professor Deyi Mbelani, the current director of Rhodes University’s Institute for the Study of Englishes in Africa. He told me many stories about Mr August’s leadership, that I only wish I had time to share with you now. I put it to Professor Mbelani that, having read about Mr August, the word that stood out for me was “dedication.” He agreed that “dedication” was the word, but that I must not leave out another: “vision”. It is Mr August’s status as a visionary that best defines him, he said. Going back over the above, I think he is right. Mr Chancellor I have the honour to request you to confer the degree of Doctor of Laws honoris causa on the Mr Tandabantu Tennyson August. *The above citation draws heavily on documents submitted as part of the honorary doctorate nomination process and others compiled by the Division of Communications and Advancement. - Tom Martin.

He was also an accomplished rugby player of international standing. While at Lovedale College, he was selected to represent Border and then the South African African Rugby Board, playing England in Gqeberha in 1972, in a team that would later be known as the black springboks. He eventually received his green and gold springbok blazer as just recognition of his achievement. He incorporated his love of sport into his vision for the youth under his care, as part of his overriding mission of educating the whole person. He got everyone involved in sport, if not as a player, then as a supporter. Especially during his time as principal of Ndamase High School, I am led to believe, it was extremely intimidating for opposing teams to play them. Not only at Ndamase home games, but especially at their away games. There would be one bus for the team players, and six buses for the supporters. From 1986 – 1990: he was president of the Transkei schools` sports union (TSSU). But there’s yet another thing I haven’t mentioned. In 1981, just as his career as an educational leader was really taking off, he was involved in a terrible motor vehicle accident. It left him permanently disabled and, for much of his life, a wheelchair user. Rather than stopping him, it simply added another string to his bow, now as an advocate for the disabled. From 2012 – 2022: Chairperson Eastern Cape South African National Association For Special Education (SANASE): this organization cater for the education and wellbeing of learners with disabilities and special needs. In 2023, he was the national deputy president of the same organisation. From 2013 – to date: he is a Board Member on the National Council of & for persons with disabilities (NCPD). I had the pleasure of an extensive conversation with one of Mr August’s former pupils at Ndamase High, Professor Deyi Mbelani, the current director of Rhodes University’s Institute for the Study of Englishes in Africa. He told me many stories about Mr August’s leadership, that I only wish I had time to share with you now. I put it to Professor Mbelani that, having read about Mr August, the word that stood out for me was “dedication.” He agreed that “dedication” was the word, but that I must not leave out another: “vision”. It is Mr August’s status as a visionary that best defines him, he said. Going back over the above, I think he is right. Mr Chancellor I have the honour to request you to confer the degree of Doctor of Laws honoris causa on the Mr Tandabantu Tennyson August. *The above citation draws heavily on documents submitted as part of the honorary doctorate nomination process and others compiled by the Division of Communications and Advancement. - Tom Martin.

- Description: Water shortages are becoming increasingly common and raising awareness thereof has been proposed as a key strategy for empowering citizens with knowledge relevant to promoting water sustainability. This knowledge should incorporate indigenous knowledge, which is unique and confined to a particular culture. Indigenous knowledge has been recognised as the key to sustainable social and economic development. Knowledge incorporated within appropriate technologies can be a transformative solution to promote sustainable consumption of natural resources. This study aimed to develop a framework with strong theoretical connections that can be used as a guide for designing and developing technological solutions for promoting knowledge, attitude, and practices (KAP) of water sustainability. Gamification, serious games, and community social networks were identified as appropriate technologies for implementing these solutions. Design Science Research (DSR) was an appropriate research methodology for this research. As the requirement of the DSR methodology, a framework was designed that considered relevant theories. The two theories (Self-Determination Theory and Social Capital Theory) were incorporated into the framework. The framework can guide other researchers in developing gamified systems that promote the KAPs of water sustainability. This framework was the theoretical artefact of the study. The research context was the Eastern Cape Province of South Africa where the data was collected from two municipalities namely, the Nelson Mandela Bay and Buffalo City Metro, which have both experienced water shortages in recent years. Quantitative and qualitative data collection methods were used. Qualitative data was collected from brainstorming sessions and expert reviews that were conducted with various stakeholders that assisted with designing and evaluating the prototype designs of the gamified solution. For the design of the study’s artefacts, a participatory research approach was adopted. Participants were recruited to complete an online survey, which ran for three months. The findings revealed that citizens’ knowledge is closely correlated to the attitudes and practices of citizens regarding water sustainability. In addition, the findings showed that the knowledge of the citizens in the Eastern Cape Province was relatively low on water practices such as conservation and filtering methods. These results were considered in the design of the practical artefact and the instantiation findings. One limitation of this study was the limited number of indigenous participants in the survey. Other limitations were the lack of experts with indigenous knowledge and the lack of indigenous knowledge documentation. The promotion of water sustainability knowledge in communities would be more effective with the use of gamification and social community networks. In principle, the enhancement in water sustainability knowledge would promote the citizens’ good practices and attitudes (behavioural) related to water sustainability. Since 2015, a significant portion of South Africa's Eastern Cape Province has been suffering from a severe drought. This province is one of the regions of the country where weather patterns have changed dramatically, and as a result, most households were left vulnerable to the water shortage problem. While the broad topic of water sustainability is widely discussed in the literature, the role of appropriate technologies in promoting knowledge of water sustainability is still under-researched. This gap provided a significant potential for investigation by sustainability to design a technological and theoretical solution for promoting knowledge of water sustainability. This study contributes to the body of knowledge by delivering three DSR artefacts namely, a Framework for Designing a Gamified System that Promotes Knowledge of Water Sustainability; the design guidelines that supplement the framework, and a practical instantiation of the framework. , Thesis (DPhil) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2024

- Description: Many academically orientated persons aspire towards having postgraduate qualifications for various reasons. The reasons range from career development to expanding their knowledge in fields related to their current areas of professional specialisation. Some people however do not fulfil that personal need due to academic exclusion from their studies in the university related to taking too long to finish their studies while others just drop out. The current study aimed to develop a model that would assist in facilitating the supervision of postgraduate nursing students to complete their studies in the required and allocated time at nursing education institutions in Gauteng. The objectives of the study were to: explore and describe the perceptions of postgraduate research nursingstudents regarding their preparedness for a joint research journey; explore and describe the perceptions of research supervisors regarding theirpreparedness for a joint research journey; develop a conceptual framework that would underpin the development of amodel to facilitate the preparedness of postgraduate research nursing students(PGRNSs) and supervisors for the research journey at NEIs in Gauteng; and develop and describe a model to facilitate the preparedness of postgraduateresearch nursing students (PGRNSs) and inexperienced research supervisorsfor a joint research journey at NEIs at Gauteng. A theory-generative research design based on a qualitative, explorative, descriptive, and contextual research approach was adopted in this study. Purposive sampling was used to select 16 postgraduate nursing students (8 master’s and 8 doctoral) and 12 research supervisors from universities in Gauteng, South Africa. Data collection was conducted through voice-recorded unstructured interviews, which were transcribed verbatim and analysed using Tesch’s open coding method of data analysis. To ensure the trustworthiness of the study, the researcher used various strategies based on the criteria recommended in Guba’s model of trustworthiness. The criteria were credibility, transferability, confirmability and dependability. Ethical principles, such as respect for a person’s beneficence, non-maleficence, and justice were ensured during the data collection stage. Four broad themes (see Chapter 3) emerged from the data analysis. The themes were: Theme: perceptions regarding postgraduate supervision provided or received Theme: perceptions regarding preparedness for the research journey Theme: support systems influencing preparedness for the research journey Theme: Hope for change in the research progress and concerns to be considered Concept identification and analysis assisted the researcher in putting concepts in a relationship for the development of the model as guided by the six survey elements of Dickoff and James. Although the model was not tested, the researcher and the selected nursing experts were confident that the model is significant to nursing and other disciplines. The model was described and successfully evaluated by a panel of six nursing experts who acknowledged the clarity, generality, accessibility, simplicity, and significant contribution to the nursing environment. The guidelines and recommendations to implement the model in the nursing environment were developed to enhance the application of the model. The model aims to provide a theoretical and structural frame of reference to the head of the department and research supervisors in nursing for the facilitation of the preparedness of the postgraduate students and inexperienced supervisors for a joint research journey to ensure the timeous completion of postgraduate studies. The outcomes of the model include easing the struggle of students during their research studies for acceptable progress within the nursing environment of nursing education institutions. inexperienced research supervisors who experienced challenges to achieving optimum supervision in the nursing environment will also benefit if they apply the developed model. To enhance the applicability of the model, the researcher recommends that the model be tested in postgraduate studies for future benefits before implementation. , Thesis (PhD) -- Faculty of Health Sciences, School of Clinical Care & Medicinal Sciences, 2024

- Description: Universal access to antiretroviral drugs is still a challenge in developing nations. This promoted an investigation into an efficient process towards the synthesis of zidovudine (AZT), a nucleoside reverse transcriptase inhibitor (NRTI) that is used to treat HIV/AIDS. It was the first antiretroviral drug approved by the FDA and it is still widely used today. AZT works by blocking the enzyme reverse transcriptase, which is used by HIV to copy its genetic material. This prevents HIV from replicating and spreading throughout the body. AZT is usually taken in combination with other antiretroviral drugs. AZT was originally used as a single-drug therapy, but it is no longer recommended for this purpose as HIV can become resistant to AZT if it is used alone. Consequently, AZT is most commonly used as part of a combination therapy; this means that it is taken with other antiretroviral drugs. This helps to prevent HIV from becoming resistant to AZT. AZT can be used to prevent mother-to-child transmission of HIV; it is usually given to HIV-positive women during pregnancy and childbirth. AZT can also be used to treat post-exposure prophylaxis (PEP); this is a course of antiretroviral drugs that is taken after a possible exposure to HIV. The application of continuous flow microreactors to reaction chemistries, such as this, could provide a potentially practical solution that could be used to meet the rising needs for antiretroviral drugs in Africa and to give new opportunities for efficient local drug manufacture. Consequently, the focus of this research was to develop safe and efficient processes towards AZT by taking advantage of micro reactor technology. Furthermore, since there is no literature on continuous flow synthesis of this drug, this research extensively unearthed interesting continuous flow processes towards zidovudine. , Thesis (PhD) -- Faculty of Science, School of Biomolecular & Chemical Sciences, 2024

- Description: The nutrition transition, characterised by a shift from traditional, nutrient-dense diets to Westernised, energy-dense, and nutrient-poor diets, has significant health implications globally. In South Africa (SA), particularly among the isiXhosa-speaking population in Nelson Mandela Bay (NMB), this transition has led to the dual burden of undernutrition and overnutrition, increasing the prevalence of non-communicable diseases (NCDs) such as obesity and diabetes. Despite the prevalence of this nutrition phenomenon, limited research has explored the perceptions of nutrition transition among South African communities, although there is literature about the transition itself. Most studies on the research subject were undertaken in Asian and European countries and America. Generally, studies regarding the nutrition transition emphasise the importance of early public health interventions to prevent the transition from reaching critical levels. This research study aimed to answer the question: How do isiXhosa-speaking people in NMB perceive nutritional transition, and what are their knowledge and practices concerning traditional foods? This study’s primary aim was to identify and evaluate the NMB isiXhosa-speaking population’s perceptions regarding nutrition transition and their knowledge and practices concerning traditional foods. Subsequently, the study aimed to develop and test an educational intervention to promote traditional African diets and mitigate the adverse effects of nutrition transition. The researcher employed a multi-method approach, encompassing quantitative and qualitative methods and an exploratory, descriptive, and contextual approach to enhance the research design. Ethical principles guided the study, including autonomy, non-maleficence, beneficence, and justice. The study comprised two phases. Participants were selected through a stratified, clustered sampling technique. In the first phase, data were collected through in-depth interviews, focus group discussions (FGDs), a 24-hour dietary recall questionnaire, and a knowledge and practices The participants were isiXhosa-speaking NMB residents older than 18 years of age. The second phase utilised the first-phase findings to develop an intervention programme. The intervention was implemented, and its efficacy was evaluated through post-intervention surveys, sensory evaluation, and a three-month telephonic follow-up. The findings indicated a significant decline in traditional food knowledge (TFK) and practices among the participants, with a marked shift towards Westernised diets. The primary factors driving this transition were urbanisation, economic constraints, and a lack of awareness about the nutritional benefits of traditional foods. The intervention programme, which included educational workshops and a sensory evaluation using indigenous crops, resulted in improved knowledge and practices regarding indigenous crops among the participants. Post-intervention data showed increased dietary diversity and a greater inclusion of traditional foods in daily diets. The study concluded that nutrition transition poses a significant challenge to the health and well-being of isiXhosa-speaking individuals in NMB. However, targeted interventions that promote traditional African diets can effectively address this issue. The study recommends that policymakers and public health practitioners incorporate culturally relevant and community-driven strategies to promote traditional food consumption. Future research should focus on the long-term impacts of such interventions and explore scalable models for broader implementation. , Thesis (PhD) -- Faculty of Health Sciences, School of Behavioural & Lifestyle Sciences, 2024

- Description: ICT plays a very important role in transforming organisations as well as governments around the world through eGovernment. A good implementation of eGovernment promises to transform and enhance the provision of services to citizens. The benefits of eGovernment will enable the transparency of government and engender the trust of its citizens therein. Citizens will have access to online government services that will minimise the long queues that citizens need to endure to access government services. eGovernment implementation requires ICT technologies, however, dependency on the implementation of ICT technologies to drive eGovernment initiatives will not alone succeed in transforming the delivery of services in government. Therefore, the implementation of ICT technologies in government must be focused on good IT governance principles. Such principles enable the executive council and management to direct and control the application both now and in the future of use of ICT in government. Therefore, this study develops a strategy artefact that is focused on good IT governance principles to assist in the execution of eGovernment programs in the Eastern Cape Provincial Government. , Thesis (MPhil) -- Faculty of Engineering, the Built Environment, and Technology, School of Information Technology, 2024

- Description: International assessments indicate that mathematics education in South Africa is still in a crisis of significant proportions. This is reflected in the low pass rate of Grade 12 mathematics learners in South Africa in general, and in the Eastern Cape Province in particular. In response, the Govan Mbeki Mathematics Development Center (GMMDC) of the Nelson Mandela University (NMU) in the Eastern Cape developed an intervention strategy. A Techno-Blended support Model for teaching and learning mathematics (TBM), used as an intervention strategy, provides learners with potential from disadvantaged communities and under-resourced schools with 21st-century education technology. The defining features of the strategy which distinguishes it from others are that it is technology-enhanced, providing the learner access to mathematics teaching and learning without the need for Internet connectivity, that is, offline, incorporating blended learning into the approach. This ex-post study, using secondary analysis, evaluates the impact of the defining features of the strategy on learners' self-directed learning skills acquisition or enhancement for mathematics learning. Firstly, statistical analysis of secondary qualitative and quantitative data in a mixed methods approach, with primary qualitative data integrated into the secondary qualitative data employing quantification, is undertaken. The quantified data is then compared with the quantitative data (methodologic triangulation technique).

- Description: International assessments indicate that mathematics education in South Africa is still in a crisis of significant proportions. This is reflected in the low pass rate of Grade 12 mathematics learners in South Africa in general, and in the Eastern Cape Province in particular. In response, the Govan Mbeki Mathematics Development Center (GMMDC) of the Nelson Mandela University (NMU) in the Eastern Cape developed an intervention strategy. A Techno-Blended support Model for teaching and learning mathematics (TBM), used as an intervention strategy, provides learners with potential from disadvantaged communities and under-resourced schools with 21st-century education technology. The defining features of the strategy which distinguishes it from others are that it is technology-enhanced, providing the learner access to mathematics teaching and learning without the need for Internet connectivity, that is, offline, incorporating blended learning into the approach. This ex-post study, using secondary analysis, evaluates the impact of the defining features of the strategy on learners' self-directed learning skills acquisition or enhancement for mathematics learning. Firstly, statistical analysis of secondary qualitative and quantitative data in a mixed methods approach, with primary qualitative data integrated into the secondary qualitative data employing quantification, is undertaken. The quantified data is then compared with the quantitative data (methodologic triangulation technique). Secondly, the theory-based Contribution Analysis is undertaken to increase the validity and credibility of the findings of the statistical analysis, providing an additional layer of triangulation. The study revealed that providing 21st-century digital education technology for use offline, within a blended learning environment, leads to a significant improvement in learner mathematics knowledge; conceptual understanding; positive self-perceptions; and finally, to the required intrinsic motivation to learn. Analysed data, obtained from the original study, indicates a positive correlation between learners who participated in the intervention strategy and enrolment in STEM-related courses at tertiary institutes. , Thesis (DPhil) -- Faculty of Education, School of Postgraduate education, 2024

- Description: This study focuses on Amagqirha kwa Xhosa (diviners) who are traditional healers within the Xhosa community. Despite their impact and footprint in the communities, there is limited knowledge regarding their role in managing mental health illnesses, particularly the kind of techniques they employ. In light of this, the study is aimed at exploring the types of techniques and interventions utilized by Amagqirha kwa Xhosa in treating psychological problems and assessing how the knowledge can be incorporated into the training of psychologists. The study employed a qualitative approach with semi-structured one-on-one interviews, using purposive and snowballing sampling strategies. Eight traditional healers from the Nelson Mandela Bay municipality, Eastern Cape, participated in the study, and thematic data analysis was utilised to analyse the data. Two primary themes were revealed in Amagqirha’s experiences with treating mental illness, and the first set core themes are 1. Ukuxilonga (Diagnosing) and 2. Izinto ngokwa ses’Xhoseni ezenza ingulo ye ngqondo (Xhosa Realities and Causes of Mental Illnesses). The second set of core themes revealed Amagqirha’s treatment methods and interventions, and these are 1.Indlela Zokunyanga Zesintu (Tradition Methods of Healing) and 2.Impawu zoxilongo olunemiphumela zobuGqirha (Treatment efficacy in traditional healing). The findings highlight the importance of recognizing diverse knowledge systems in Mental Health care, emphasizing the need for culturally sensitive approaches that respect and take into account cultural context and spirituality of the community/patients. Additionally, the study provides guidelines for mental health practitioners when dealing with clients who align with paradigms other than the Western biomedical paradigm or worldview, highlighting the importance of integrating varying paradigms in approaching mental health practice. , Thesis (MA) -- Faculty of Health Sciences, School of Behavioural & Lifestyle Sciences, 2024

- Description: The main research question for this treatise is to determine whether the South African legal framework provides effective regulations in curbing violent and intractable strikes. To answer the research question, the research explored the evolution of the right to strike in South Africa, analysing its socio-economic impact and the transition from a repressive regime to a democratic one. The study assessed international, regional, and national legal frameworks, focusing on the right to strike and its regulation. Amendments to the LRA, including introducing rules for picketing, mandatory secret ballots for strikes, and advisory arbitration for dysfunctional strikes, were evaluated. The findings indicate that while these amendments represent a significant step in addressing the issues of violent strikes in an employment context, their effectiveness is limited. Persistent challenges include the frequent disregard by trade unions and their members for legal measures. This reflects the deeper socio- economic and political issues. The study suggests that the effectiveness of these legislative changes is hindered by ongoing social and economic inequalities, highlighting the need for broader socio-political solutions beyond legislative amendments. This comprehensive analysis explains the complexities surrounding strike actions in South Africa and the balance between upholding labour rights and maintaining workplace discipline and order. , Thesis (LLM) -- Faculty of Law, School of Mercantile Law, 2024

- Description: Benteler Automotive in the Eastern Cape has experienced challenges over the past five years due to a high rate of staff turnover at the leadership and management levels. As a result, the morale of the employees in the organisation was affected, resulting in decreased levels of job satisfaction, and productivity, high rates of absenteeism, and staff turnover. Hence, this study was conducted to assess employee morale and leadership styles and examine the impact of motivation, leadership styles, and human resource strategies on staff morale, with the intention of proposing managerial interventions to enhance employee morale within the organisation. The study was conducted within a positivist paradigm, and a quantitative research approach was used to investigate the phenomenon. Data were collected from a sample of 300 employees using a closed-ended questionnaire survey, and a response rate of 93% was achieved. The Statistical Package for Social Science (SPSS) Version 21 was used for analysing and reporting on data in line with the research objectives of the study. The analysed data were reported under descriptive and inferential statistical headings, where frequency of the Likert scale responses, measures of central tendencies, Pearson’s correlations, regression analysis, and analysis of variance (ANOVA) were reported. The results of the study indicates that motivation, leadership styles and human resource strategies have a significantly positive influence on employee morale. On the other hand, the results also indicate, in general, that respondents were indifferent to most of the statements pertaining to leadership styles and human resource strategies. The study recommends that management consider implementing fundamental theoretical human resource strategies to enhance employee morale. These strategies include fostering human relations, providing continuous training opportunities to enhance employee knowledge, promoting new skills development, boosting self-confidence, and addressing concerns about job stability. The results of the study have provided practical and conceptual managerial and academic benefits within the field of management and leadership. A future study on the evaluation of the impact of leadership styles and cultural elements on employee morale is an essential element to consider, as it was not covered in this study. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2024

- Description: This study investigates the sustainable growth of taverns within the informal liquor industry in Gqeberha, South Africa. The informal sector is critical for economic development, employing 60% of the world's population and nearly 30% of South Africa's workforce. This study focuses on taverns, a prevalent form of small, medium, and micro-enterprises in South African townships. Despite their economic significance, these taverns face numerous challenges, including limited access to finance, inadequate infrastructure, regulatory hurdles, and competition from larger formal enterprises. The research explores the historical context of the liquor industry in South Africa, highlighting the legacy of racial inequality and the evolution of regulatory frameworks aimed at balancing industry growth and social equity. In addition, the literature covered topics relating to SMMEs and sustainable growth. The study employs a case study strategy and a qualitative methodology where 12 tavern owners in Gqeberha were interviewed using an interview schedule. The thematic data analysis revealed five main challenges that hinder taverns' sustainable growth, namely finance, government interventions and facilities, competition, the COVID-19 Pandemic and crime. In addition, three measures or themes of sustainable growth were identified for these enterprises, such as economic, social and environmental measures for sustainable growth. Finally, based on the findings, a major contribution of this study is the framework of sustainable growth enablers that were presented to SMMEs, including taverns. This study contributes to the understanding of SMMEs in the informal sector and offers practical recommendations for enhancing the sustainable growth of taverns. By addressing the identified challenges and leveraging the proposed enablers, policymakers and stakeholders can create a more supportive environment for these enterprises, ultimately contributing to broader economic development and poverty reduction in South Africa. The insights gained from this study are intended to inform future policies and support mechanisms that can help these enterprises thrive despite their myriad challenges. , Thesis (MCom) -- Faculty of Business and Economic Sciences, School of Management Sciences, 2024

- Description: Grassy ecosystems are essential for human survival, providing key services including food production, water provisioning and moderating climate. Yet, grassy ecosystems remain undervalued due to misconceptions that they are remnants of degraded states of forest – a view that continues to influence climate change policies. This thesis explores the links between wild, free-roaming ungulate grazers and climate drivers, including carbon storage and surface albedo (i.e., reflectance of solar radiation), through their impacts on vegetation and soils. Using black wildebeest (Connochaetes gnou) as a model wild species, I compared their grazing patterns in an Afromontane grassland in the eastern Karoo, South Africa, to those of short-duration cattle grazing systems in similar nearby grasslands (Chapter 2). While short-duration grazing aims to mimic spatiotemporal wild ungulate grazing patterns to supposedly enhance ecosystem functioning and soil carbon stocks, I found that wildebeest had ~50% shorter grazing durations and much shorter rest intervals (1-5 days versus 60-365 days), revealing key differences in grazing patterns that may affect vegetation and climate feedbacks. Next, I examined spatial variations in soil organic carbon (SOC) stocks between grass growth forms that differ in grazing tolerance (Chapter 3). Red grass (Themeda triandra) tussock patches, sensitive to frequent grazing, had higher SOC to a soil depth of 20 cm (61.45 ± 1.59 Mg C·ha-1)than intensively grazed, prostrate-growing Cynodon dactylon grazing lawns (55.43 ± 3.40Mg C·ha-1), likely due to greater shading and soil moisture beneath tussocks which drives microbial decomposition. Seasonal albedo variations were then assessed across distinct grassland patch types among seasons to determine whether albedo varies seasonally at fine patch-scales between grass patches, between shrub and grass patches, and with grazing (Chapter 4). Albedo was lower during the growing season compared to dormancy, and was consistently lower in dwarf shrub (Pentzia incana) encroached patches compared to grass patches. No albedo differences between grazed and less-grazed tussock grass patches of the same species were found, although intensively grazed grazing lawns had consistently higher albedo than most patch types. Finally, I evaluated trade-offs between plant carbon, albedo, and their impacts on radiative forcing (i.e., atmospheric warming/cooling) resulting from patch type changes commonly found in grassy ecosystems (Chapter 5). The loss of perennial grass cover resulted in the highest net positive (warming) effect, mostly due to reduced root biomass. Additionally, shrub encroachment into all patches lowered albedo, but led to negative (cooling) effects from shrub encroachment into bare ground patches due to biomass gains. This thesis challenges current views of grassy landscapes and short-duration grazing systems, emphasizing the need to rethink climate change mitigation strategies to prioritize maintaining heterogeneity, while enhancing carbon sequestration and albedo in grassy ecosystems. , Thesis (PhD) -- Faculty of Science, School of Environmental Sciences, 2024
