- Description: The quality of nursing care delivery is closely tied to positive patient outcomes and satisfaction. However, in Ghana's public hospitals, particularly in the Bono region, the standard of nursing care often falls short. Media reports have highlighted instances of poor nursing care, leading to increased patient morbidity and mortality in this area. Consequently, this study aimed to develop strategies that could be implemented by stakeholders to optimize the quality of nursing care for patients in public hospitals within the Sunyani municipality in the Bono region of Ghana. The Donabedian model of quality was the theoretical framework that underpinned this study. A qualitative, explorative, descriptive and contextual research design was employed. The study was conducted in four phases: Phase One: This empirical phase explored and described participants' perceptions of nursing care quality in Bono region's public hospitals. Data were collected through semi-structured interviews including purposively selected patient participants (n=18), professional nurses (n=18) and nurse managers (n=3) and analysed qualitatively following Creswell and Tesch’s (2021) six-step process. From this analysis, three main themes related to perceptions emerged-facilitators of, barriers to and outcomes of quality nursing care—and were thoroughly discussed. Phase Two: An integrative literature review was conducted to search, select, appraise, extract, and synthesise existing relevant literature on quality nursing care in public hospitals of lower to middle-income countries (LMICs). This review followed four stages recommended by Whittemore and Knafl (2005). The identified literature was critically appraised using the John Hopkins Nursing Evidence and Non-Research Evidence appraisal tools. The appraised literature was analysed, yielding nine strategies for optimizing the quality of nursing care in public hospitals from 12 articles under two themes: “Daily nursing care-related strategies” and “Organizational related strategies”. Phase Three: The findings from Phases One and Two were synthesised to develop a conceptual framework for strategies to optimize quality nursing care in Bono region's public hospitals. This framework was based on Dickoff et al.’s (1968) theory development outline. The resulting framework guided the drafting of the (I-CARE) strategies, an acronym for Implementing ABSTRACT v organizational strategies, Commitment to attributes and practices, Augmenting outcomes, Rendering holistic and patient-centered care, and Enhancing resources and support for quality nursing care. Phase Four: The I-CARE strategies were reviewed and validated by four experts with extensive backgrounds in strategy development and quality nursing care. The experts' modifications and recommendations were incorporated in finalizing the strategies. The strategies, when implemented, are expected to enhance the optimization of nursing care quality in Bono region's public hospitals, ultimately leading to better patient outcomes and satisfaction. , Thesis (PhD) -- Faculty of Health Sciences, School of Clinical Care & Medicinal Sciences, 2024

- Description: When an employer subjects an employee to a formal disciplinary process, the employer appoints a presiding officer to whom it cedes either wholly or partly its decision-making powers. Wholly in that the presiding officer would render a finding and impose a sanction. Partly, in that the presiding officer would render a finding and only provide the employer with a recommendation on sanction, which the employer would either accept or reject. The State in its capacity as employer has been afforded the ability to utilise section 158(1)(h) of the Labour Relations Act, 1995 (LRA) to review the decisions of presiding officers appointed over internal disciplinary proceedings. Despite the wording of section 158(1)(h), the courts have restricted its use by employees employed by the State. The courts have held that a State employee would have to utilise the ordinary dispute resolution pathways made available in the LRA to challenge the decisions the State takes in its capacity as an employer. When exercising the prerogative to discipline, all employers, including the State, must primarily comply with the substantive and procedural requirements outlined in Schedule 8 of the LRA. Notwithstanding the primary measure of fairness, the employer’s decision to discipline and dismiss would also be pitched and measured against its adopted internal disciplinary code and procedure document. It has been questioned in a Labour Court judgement whether the State should continue to be afforded the benefit of the section 158(1)(h) review. The Labour Court judgement ventures into the consequences the use of section 158(1)(h) would have on the unfair dismissal dispute resolution pathway afforded by the LRA and proposed that it would be ideal for the State to utilise alternatives when attempting to alter the sanction or finding of its internal presiding officers. The alternatives proposed include the internal review of findings or sanctions, the unilateral substitution of sanctions, increasing sanctions on appeal and the practice of subjecting the employee to a second hearing. Applying the alternatives to the current circumstances and collective bargaining agreements applicable in the public service, the State would not be able to utilise the alternatives, save for subjecting the employee to a second hearing in exceptional circumstances. In all other instances, including convening an internal review, increasing a sanction during an appeal, or unilaterally substituting the sanction would conflict with the prevailing internal disciplinary code and procedure in the public service. In as much as the Labour Court judgment attempts to put into perspective the consequences the use of section 158(1)(h) would have on the subsequent dispute resolution pathways, the State should not be unduly bound by irrational findings or sanctions imposed by presiding officers appointed to preside over its internal disciplinary hearings. , Thesis (LLM) -- Faculty of Law, School of Mercantile Law, 2024

- Description: The public sector infrastructure departments in South Africa rely on construction companies as the major stakeholders in the implementation and maintenance of infrastructure facilities including schools. The Limpopo Province is faced with a serious challenge of underperforming contractors. This in turn affects the Provincial Government’s effective delivery of the much-needed quality infrastructure and facilities. A significant number of schools in the province are faced with infrastructure challenges including sanitation facilities, deteriorating school buildings, storm damage, inadequate infrastructure for special schools, water provision, and general maintenance. This study sought to understand the challenges faced by contractors and further explored whether the effective application of project management methodologies can have a positive impact on improving the current underperformance. Due to the nature of the study, a qualitative research method was employed to collect data. An interpretivist paradigm was adopted as the research philosophy, as it allowed for a flexible and in-depth investigation approach. The study utilized an exploratory research design. The targeted population for the study was carefully selected to obtain relevant and reliable data, and a purposive sampling technique was chosen. Semi-structured interviews were conducted as the primary data collection method, enabling the collection of first-hand information. To ensure accuracy and prevent loss of information, the research process involved recording and transcribing the interviews, using an inductive analysis approach. Eighteen out of the twenty targeted participants were successfully interviewed, resulting in a response rate of 90%. The findings of the study revealed that poor planning, inadequate financial management, inexperienced staff, interference from stakeholders, and a misunderstanding of project scope were among the many factors contributing to poor contractor performance. Furthermore, contractors, particularly Small and Medium Enterprises (SMEs), faced serious challenges during project implementation, including a lack of proper training, budget constraints, and delayed payments from clients. Based on the study's findings, it is recommended that contractors invest in planning and cost management software, including project management methodologies such as Agile, Waterfall, and MS Project. Further, contractors are encouraged to employ adequately skilled and qualified site personnel. Clients should also consider supporting underperforming contractors by pairing them with proven-performing ones to encourage mentorship and other forms of capacity building. , Thesis (MSc) -- Faculty of Engineering, the Built Environment, and Technology, School of Building and Human Settlements Management, 2024

- Description: In South Africa, learning in the Foundation Phase happens in a child’s home language, thus all eleven official languages, nine of them being African languages, must and are used as languages of teaching and learning in this phase. Teacher training, however, does not happen in all eleven official languages. The dominant language of training teachers across the country is English, even in classroom contexts where the language of learning and teaching may be an African language. This raises concerns about whether student teachers trained in English can translate mathematics content knowledge into an African language. This is particularly concerning given the country’s consistent underperformance in mathematics and literacy. Against this backdrop, this qualitative study aimed to explore Foundation Phase student teachers’ perspectives on their experiences of teaching mathematics using isiXhosa during teaching practice. The question that this study sought to answer was: what are student teachers’ perspectives on their experiences of teaching mathematics in isiXhosa during teaching practice? Drawing upon classroom observations and semi-structured individual interviews as the primary methods of data collection, the study explored the mediation of mathematics learning using isiXhosa, the pedagogical challenges encountered by student teachers, the strategies employed to address these challenges, and the influence of university training on their preparation. Findings reveal a significant discrepancy between the language of instruction used in university training which is English, and the language required for teaching practice which is isiXhosa. Student teachers expressed struggles in translating theoretical knowledge into practical application, leading to diminished confidence and pedagogical inefficacy. However, participants also demonstrated resilience through innovative strategies such as code-switching, visual aids, and collaborative learning approaches. The study highlights the urgent need for comprehensive language support and pedagogical training programmes to bridge the gap between theory and practice in isiXhosa-medium mathematics instruction. Recommendations are provided for educational institutions, especially the case study university, to enhance the preparation of student teachers and promote effective mathematics education in multilingual contexts. , Thesis (MEd) -- Faculty of Education, School of Primary School Education: Foundation Phase, 2024

- Description: Undergraduate nursing students worldwide experience stress and anxiety due to the demands of nursing education, which include challenges related to academic workloads and the clinical environment. This, in turn, may impede programme completion and continuation in nursing careers. Resilience is recognised as an effective attribute for nursing students in adapting to stressors and has been found to have a beneficial impact on learning experiences, academic performance, and professional practice. Despite numerous research studies conducted on resilience in the health professions, there remains little empirical work that has explored undergraduate nursing students' understanding and experience of their resilience. The purpose of this study was thus to explore undergraduate nursing students’ perceptions of their resilience at a nursing education institution in the Eastern Cape, South Africa, and to compile recommendations for a resilience training programme in undergraduate nursing education. A qualitative, explorative, descriptive, and contextual research design was implemented, with the study underpinned by the Resilience Ecological Stress Model. Third and fourth-year nursing students were recruited by purposive sampling, following which data was collected online by means of eleven individual semi-structured interviews conducted and recorded on the Microsoft (MS) Teams platform. Data was analysed using Braun and Clarke’s six steps of reflexive thematic analysis, generating codes and themes. The following themes were identified: participants’ perceptions of their challenges while studying nursing, participants’ understanding and experience of resilience, and participants’ views on the unique requirements of the degree in nursing. Findings indicated that nursing students perceive resilience as a beneficial attribute in mitigating the stress and anxiety evoked by their diverse challenges. Recommendations for nursing education were formulated based on the theoretical framework constructs and the findings of the study. , Thesis (MCur) -- Faculty of Health Sciences, School of Clinical Care & Medicinal Sciences, 2024

- Description: The pervasive underdiagnosis and undertreatment of mental health issues among males, exacerbated by societal expectations of masculinity, represent a significant public health concern. This study addresses the critical gap in understanding how sociocultural constructs of masculinity influence mental health help-seeking behaviours among males in South Africa, a context marked by high rates of crime, violence, substance abuse, and male suicides. Adopting a qualitative research approach, this study conducted in-depth interviews with 12 participants, employing convenience and snowball sampling techniques to achieve data saturation. Thematic analysis was utilised to systematically identify and interpret patterns of meaning within the data, focusing on participants' understandings of mental health, the impact of sociocultural constructions of masculinity on their help-seeking behaviours, and the barriers they encounter. The findings illuminate the profound impact of sociocultural constructs of masculinity on male mental health help-seeking behaviours, revealing significant barriers rooted in societal stigma, traditional masculinity norms, and a lack of tailored mental health services. The study also introduces a conceptual model illustrating the influences on mental health acknowledgement and help-seeking behaviour among males in South Africa, underscored by a reflective analysis of exploring male emotional well-being. This study highlights the urgent need for culturally sensitive mental health care interventions that address the unique challenges faced by men in South African communities. By challenging societal norms and advocating for improved mental health awareness and services tailored to men, this research contributes to the broader discourse on gender, mental health, and social change, offering insights for researchers, policymakers, and practitioners aiming to enhance male mental health outcomes. , Thesis (MA) -- Faculty of Health Sciences, School of Behavioural & Lifestyle Sciences, 2024

- Description: Radiographers use ionising radiation to produce radiographic images and the use of ionising radiation in healthcare has both benefits and risks for patients and healthcare professionals. It is therefore important that radiographers mitigate the risks associated with ionising radiation. It is for this reason that radiation protection measures are applied to ensure the safety of patients, staff, and the public. Furthermore, radiographers are also responsible for mentoring radiography students and inculcate the use of radiation protection measures when students undergo their workplace learning. This mentoring takes place in the clinical setting with its characteristics that may or may not advance the application of radiation protection measures. The aim of this study was to investigate the lived experiences of final-year undergraduate radiography students applying radiation protection measures in the clinical setting and to propose strategies to foster the integration of radiation protection theory into clinical practice. This study was located in the interpretivist paradigm using phenomenology as a research method and theoretical framework to achieve the stated aim. The target population for this qualitative study included all registered final-year undergraduate radiography students at the local university who perform their WPL at the accredited training hospitals in the Eastern Cape Province as this cohort of students have more clinical experience than the first-, second- and third-year students. The target population comprised 28 students. Purposive sampling was employed to select the group of radiography students to interview. The study used phenomenological interviews as a data collection tool and the collected data was explicated using a self-developed method. The trustworthiness of the study was ensured by applying Guba’s model of trustworthiness that includes credibility, transferability, confirmability, dependability and authenticity and was further enhanced by reflecting on the balanced integration, openness, concreteness, and resonance of the study. This study employed an ethical framework referred to as principlism that includes the notions of autonomy, beneficence, non-maleficence and justice.Data explication was conducted using three cycles of explication. Cycle one produced interpretive profiles for each participant. The interpretive profiles revealed the life histories of each participant as well as the utterances of participants related to the three sub-questions. Cycle two produced four themes. Theme one described participants’ being with others such as radiographers, clinical supervisors, medical doctors, and patients and revealed the tension between participants’ belonging and being unwanted. Theme two characterised the clinical setting as a place where several factors flow together to provide participants with their individualised experiences. Theme two revealed the emotional distress; the learning through trial-and-error; the independent learning; learning that is coupled with humiliation as experienced by participants. The clinical space was also characterised as a place to be survived, a place where students have to be inconspicuous and understand the acceptable levels of engagement with others. It is also a place where theory and practice at times is in alignment at other times not in alignment. The clinical setting could also be a place of self-doubt and insecurity, a place of personal growth, and a place where historical events are significant. Theme three disclosed the unspoken lessons that were conveyed through the actions and behaviours of individuals in the clinical environment. Unintended lesson one is that radiation protection measures are not important. Lesson two suggest that classroom teaching about radiation protection is not valid in the clinical setting, and finally that incivility towards radiography students is acceptable. Theme four revealed the difficulties experienced by radiography students when navigating ethical dilemmas.

- Description: Radiographers use ionising radiation to produce radiographic images and the use of ionising radiation in healthcare has both benefits and risks for patients and healthcare professionals. It is therefore important that radiographers mitigate the risks associated with ionising radiation. It is for this reason that radiation protection measures are applied to ensure the safety of patients, staff, and the public. Furthermore, radiographers are also responsible for mentoring radiography students and inculcate the use of radiation protection measures when students undergo their workplace learning. This mentoring takes place in the clinical setting with its characteristics that may or may not advance the application of radiation protection measures. The aim of this study was to investigate the lived experiences of final-year undergraduate radiography students applying radiation protection measures in the clinical setting and to propose strategies to foster the integration of radiation protection theory into clinical practice. This study was located in the interpretivist paradigm using phenomenology as a research method and theoretical framework to achieve the stated aim. The target population for this qualitative study included all registered final-year undergraduate radiography students at the local university who perform their WPL at the accredited training hospitals in the Eastern Cape Province as this cohort of students have more clinical experience than the first-, second- and third-year students. The target population comprised 28 students. Purposive sampling was employed to select the group of radiography students to interview. The study used phenomenological interviews as a data collection tool and the collected data was explicated using a self-developed method. The trustworthiness of the study was ensured by applying Guba’s model of trustworthiness that includes credibility, transferability, confirmability, dependability and authenticity and was further enhanced by reflecting on the balanced integration, openness, concreteness, and resonance of the study. This study employed an ethical framework referred to as principlism that includes the notions of autonomy, beneficence, non-maleficence and justice.Data explication was conducted using three cycles of explication. Cycle one produced interpretive profiles for each participant. The interpretive profiles revealed the life histories of each participant as well as the utterances of participants related to the three sub-questions. Cycle two produced four themes. Theme one described participants’ being with others such as radiographers, clinical supervisors, medical doctors, and patients and revealed the tension between participants’ belonging and being unwanted. Theme two characterised the clinical setting as a place where several factors flow together to provide participants with their individualised experiences. Theme two revealed the emotional distress; the learning through trial-and-error; the independent learning; learning that is coupled with humiliation as experienced by participants. The clinical space was also characterised as a place to be survived, a place where students have to be inconspicuous and understand the acceptable levels of engagement with others. It is also a place where theory and practice at times is in alignment at other times not in alignment. The clinical setting could also be a place of self-doubt and insecurity, a place of personal growth, and a place where historical events are significant. Theme three disclosed the unspoken lessons that were conveyed through the actions and behaviours of individuals in the clinical environment. Unintended lesson one is that radiation protection measures are not important. Lesson two suggest that classroom teaching about radiation protection is not valid in the clinical setting, and finally that incivility towards radiography students is acceptable. Theme four revealed the difficulties experienced by radiography students when navigating ethical dilemmas. The theme revealed radiographers’ and radiologists’ indifference towards radiation protection, the non-application of radiation protection measures, and the inconsistency and apathy towards radiation protection measures. Cycle three viewed the experiences of participants through the lens of Dasein’s disclosedness. This revealed the exclusive language used by participants, the largely negative mood and participants’ disconnection from the imaging department.Finally, the study presented new and important insights by probing the topic of radiation protection in a novel way by using phenomenology to focus on the lived experiences of final-year undergraduate students applying radiation protection measures in the clinical setting.

- 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: Euthanasia remains a contentious subject of debate in countries around the world and in South Africa. The South African court system has been faced with requests for the decriminalisation of euthanasia. However, it remains illegal to practice euthanasia in South Africa. This is set by common law as there is no legislation formally regulating euthanasia. Euthanasia provides relief from suffering for patients with terminal illnesses that cause severe suffering and a decrease in their quality of life. Individual autonomy is recognised as patients are given the ability to choose how to end their lives once they make the decision to terminate their lives. In this study, an examination on physician-assisted euthanasia and its current legal position in South Africa will be conducted. Key terms are defined, such as euthanasia - distinguishing active and passive euthanasia as well as physician-assisted suicide. South African law permits the withdrawal of life-sustaining treatments which may be viewed as passive euthanasia. This is done with the consent of the patient and the medical practitioners involved are not held criminally liable should the withholding of treatment cause the death of the patient. Relevant constitutional rights will be examined to make a case for the legalisation of physician-assisted euthanasia. These rights include the right to dignity, the right to life, the right to equality, the right to freedom of religion, belief and opinion, and the limitation clause. Common law, case law and statutory law will also be considered. The recommendations of the South African Law Commission in its report (project 86) will be examined as well. An analysis will be conducted on how foreign jurisdictions have accepted physician-assisted euthanasia and implemented legislative measures to safeguard and regulate how medical practitioners practice it. Canada is an example of such a jurisdiction and an analysis has been conducted on how courts in Canada have made a case for the decriminalisation of physician-assisted euthanasia. Canadian courts relied on rights such as the right to life and freedom of opinion. viii When arguing for or against the legalisation of euthanasia, the ethical perspectives of both arguments must be considered. The ‘slippery slope’ will be discussed to demonstrate an ethical argument against euthanasia. The ethical framework of utilitarianism will be discussed as an argument for euthanasia. In line with the title of this research, the physician’s role in the process of euthanasia will also be discussed. After weighing the key arguments, this research concludes that physician-assisted euthanasia ought to be legalised in South Africa. Recommendations are further suggested on how euthanasia ought to be regulated should it be legalised. The recommendations serve as a means of addressing the possibility of abuse and illegal conduct from medical practitioners and the public. Through this study, the aim is to contribute to the debate on physician-assisted euthanasia and to advance the development of a euthanasia-related legislation in South Africa. , Thesis (LLM) -- Faculty of Law, School of Criminal and Procedural Law, 2024

- Description: Natural products have been extensively studied for their anticancer potential, and several widely used anticancer drugs have natural origins. Many studies have demonstrated that natural compounds can induce paraptosis in various tumour cell lines. Paraptosis is a caspase-independent cell death mechanism characterised by cytoplasmic vacuolation arising from the endoplasmic reticulum (ER) and the mitochondria. The molecular mechanism of paraptosis is unclear; however, the literature indicates that dysregulation of calcium signalling plays an important role in paraptosis induction, particularly calcium-mediated signalling between the ER and mitochondria. This study aimed to identify and characterise the mechanism of cell death induced by a phytocannabinoid ratio which induced significant cytoplasmic vacuolation in the MCF7 breast cancer cell line. Several techniques were employed to address the aim of the study. The crystal violet assay was used to detect changes in viability. Several pathway inhibitors, as well as fluorescent staining and analysis using high-content screening (HCS), were used to measure the induction of various cell death mechanisms. Morphological changes were investigated using light and transmission electron microscopy. The phytocannabinoid ratio induced significant cell death and cytoplasmic vacuolation in MCF7 cells; however, the same trend was not observed in the MCF10A non-tumourigenic breast cell line. No cell cycle arrest, apoptosis, necrosis, autophagy, or ferroptosis induction was detected in MCF7 cells, suggesting that an alternative mechanism of cell death was induced. Vacuolation and cell death induced by the phytocannabinoid ratio were inhibited by cycloheximide, suggesting a dependence on protein synthesis, which is characteristic of paraptosis induction. The mechanism of paraptosis induction by the phytocannabinoid ratio was investigated, and it was found that treatment 1) induced ER dilation and mitochondrial swelling; 2) induced significant ER stress, mitochondrial calcium overload, and mitochondrial dysfunction which appeared to be mediated by the voltage-dependent anion channel (VDAC); and 3) significantly impaired all mitochondrial metabolic pathways. Overall, the data demonstrated that paraptosis induced by the cannabinoid ratio is mediated by calcium flux from the ER to the mitochondria. This highlighted a novel mechanism of phytocannabinoid-induced cell death and emphasised the anti-cancer potential of the use of phytocannabinoid ratios as opposed to individual phytocannabinoids, expanding their potential for use as anticancer agents. , Thesis (PhD) -- Faculty of Science, School of Biomolecular & Chemical Sciences, 2024

- Description: As per the regulations outlined by the South African Nursing Council (SANC), nursing students must fulfil a specified number of clinical hours to become registered practitioners. Regulation R425 and R174 mandates that undergraduate nursing students complete clinical hours in General Nursing Science (GNS), including a component in the operating room (OR) as part of their specialization. However, the educational experiences of Bachelor of Nursing (BON) students in the OR setting are not always positive. The intensity and urgency of perioperative activities in the OR can sometimes leave nursing students feeling threatened and overwhelmed, hindering their ability to view the OR as a conducive clinical learning environment (CLE). The purpose of the study was to gain an understanding of undergraduate nursing students’ learning experiences of the OR environment in public and private hospitals while achieving the learning objectives for course completion. The study followed a qualitative, exploratory, descriptive and contextual design. Undergraduate nursing students based at a higher education institution (HEI) undergoing a four-year BON degree and who had exposure to the OR environment were invited to participate in the study. Data collection involved interviewing 20 participants using focus group discussions. Data was transcribed verbatim and analysed thematically using Tesch’s method of analysis. Vygotsky’s theory of sociocultural learning was used as a lens to explore the OR learning experiences of the nursing students placed at both public and private hospitals. An adapted version of the AGREE II tool was used as a framework to develop recommendations to optimise the learning experiences of nursing students in the OR environment. The analysis yielded three overarching themes and nine related sub-themes. It was evident that these students encountered challenges when adapting to the OR environment. These challenges were attributed to factors such as the reception and support they received in the CLE, their level of preparedness for OR procedures, and the numerous factors influencing their learning opportunities within the OR. The findings propose that enhancing nursing students’ preparation, along with implementing a structured induction programme, could lead to a more favourable experience in the OR and optimise learning outcomes. Additionally, fostering supportive mentorship programmes with OR professional nurses or staff trained to introduce nursing students to the OR, promoting professional communication between nursing education institutions (NEIs) and hospital OR management, are pivotal measures for maximizing learning opportunities and nurturing the professional growth of nursing students within the OR environment. Recommendations were developed using an adapted version of the AGREE II tool as a framework to optimise the learning experiences of nursing students in the OR environment. , Thesis (MCur) -- Faculty of Health Sciences, School of Clinical Care & Medicinal Sciences, 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: In this dissertation, three cross-diffusion models which require positivity-preserving solutions are solved using standard and nonstandard finite difference methods and physics-informed neural networks. The three models are a basic reaction-diffusion-chemotaxis model, a convective predator-prey pursuit and evasion model, and a two-dimensional Keller-Segel chemotaxis model. All three models involve systems of nonlinear coupled partial differential equations subject to some specified initial and boundary conditions for which no exact solution is known. It is not possible to obtain the stability region of the standard finite difference methods for the three models theoretically and therefore a range of values of temporal step size at a given spatial step size for reasonable solutions is obtained by running some numerical experiments.

- Description: In this dissertation, three cross-diffusion models which require positivity-preserving solutions are solved using standard and nonstandard finite difference methods and physics-informed neural networks. The three models are a basic reaction-diffusion-chemotaxis model, a convective predator-prey pursuit and evasion model, and a two-dimensional Keller-Segel chemotaxis model. All three models involve systems of nonlinear coupled partial differential equations subject to some specified initial and boundary conditions for which no exact solution is known. It is not possible to obtain the stability region of the standard finite difference methods for the three models theoretically and therefore a range of values of temporal step size at a given spatial step size for reasonable solutions is obtained by running some numerical experiments. It is observed that the standard finite difference schemes are not always positivity-preserving, and this is why nonstandard finite difference schemes are necessary. Chapter 1 provides some background detail on partial differential equations, cross-diffusion equations, finite difference methods, and artificial neural networks.

- Description: Tuberculosis remains a significant public health challenge due to the complexity and compliance issues of its treatment, the prevalence of latent infections, the high rate of HIV co-infection, and the spread of drug-resistant strains. This highlights the need to search for new antimycobacterial drugs. Natural products have historically been used as sources for the discovery of pharmaceuticals. Although medicinal macrofungi have been exploited in traditional folk medicines for the treatment of various diseases, research into their antimycobacterial activity remains limited.The aim of this study was to isolate, identify, and characterise the antimycobacterial compound(s) present in ethanol fruiting body extracts of Gymnopilus junonius (Fr.) P.D. Orton (Hymenogastraceae) and Rhodofomitopsis lilacinogilva (Berk.) B.K. Cui, M.L. Han, & Y.C. Dai (Fomitopsidaceae), as well as to investigate their mechanism of action and potential toxicity using in vitro and in vivo screening methods.Bioassay-guided fractionation was conducted using column chromatography and preparative thin-layer chromatography to isolate the active antimycobacterial fraction/compound from ethanol extracts of G. junonius and R. lilacinogilva. Antimycobacterial activity against M. tuberculosis H37Rv was screened using a resazurin microplate assay (REMA). The chemical structure was elucidated employing 1D-(1H NMR) and 2D NMR spectroscopy (HSQC, HMBC) techniques, along with High- Performance Liquid Chromatography High-Resolution Electron Spray Ionisation Mass Spectrometry (HPLC-HRESI-MS). Transmission electron microscopy (TEM) was utilised to observe the ultrastructural changes in M. tuberculosis induced by the active fraction/compound. Toxicity assessment was performed on African green monkeykidney (Vero) and human hepatoma (C3A) cell lines using various staining techniques to observe the potential risk for hepatotoxicity (CellRox orange, TMRE, and MTG staining) and genotoxicity (NucRed staining). In vivo toxicity of extracts was evaluated using a zebrafish embryo/larvae model to observe developmental and teratogenic effects.The bioassay-guided fractionation of G. junonius and R. lilacinogilva extracts yielded an active compound and a fraction displaying inhibitory activity against M. tuberculosis, with MIC values of 31.25 μg/mL and 250 μg/mL, respectively. Gymnopilene was identified as the main active compound isolated from G. junonius, while fraction 8 from R. lilacinogilva contained a predominant constituent resembling a pachymic acid derivative. Transmission electron microscopy revealed ultrastructural damage to M. tuberculosis cells upon treatment with gymnopilene and fraction 8, which was observed as the disruption and disintegration of the cell wall. In vitro toxicity assessment indicated a reduction in the cell density in both Vero and C3A cell lines following exposure to the fractions/gymnopilene. Although there were no significant alterations in the production of reactive oxygen species, changes in mitochondrial dynamics were observed. Genotoxic assessment showed no significant changes. In vivo toxicity assessment showed no significant effects for G. junonius against the zebrafish embryos/larvae, whereas R. lilacinogilva remained toxic and induced developmental abnormalities over a 72-hour time period.The findings of this study highlight the potential of macrofungi as a valuable source of bioactive compounds, confirming the significance of natural products in drug discovery. Notably, this research represents the first to demonstrate that the predominant compound, gymnopilene, isolated from G. junonius exhibits inhibitory activity against M. tuberculosis, contributing to the novelty of the study. Furthermore, the study expands our understanding of the antimycobacterial properties of the selected macrofungal species, G. junonius and R. lilacinogilva, by demonstrating the ultrastructural damage to M. tuberculosis cell wall induced by treatment. However, it is important to recognise the potential toxicity identified through in vitro and/or in vivo screening assays. The observed toxicity may hamper their suitability formdrug development. Future investigations could explore the inclusion of additional in vitro based models, perhaps more complex and physiologically relevant models alongside the in vivo screening model to assess the therapeutic potential of isolated fractions/compounds. , Thesis (PhD) -- Faculty of Science, School of Biomolecular & Chemical Sciences, 2024

- Description: The study highlights the misrepresentation of people with disabilities in the media, and how it can lead to social exclusion of people with disabilities and misunderstanding of the disability identity. The research question involves disability representation, wheelchair-disabled identity, illustration and participatory design. The study focuses specifically on wheelchair disability and uses a participatory design approach, which allows for wheelchair users collectively to be part of the research. The three different models of disability, namely the medical model, the social model and the cultural model. The South African definition of disability is explored, and images and photographic examples of past representations of disability are examined to identify stereotypes, such as the freak, the medicalised disabled body and the pitiful victim. Positive illustrations, paintings and posters of people living with disabilities are analysed, focusing on physical disability and representation, which reveals that illustration can instil good staring habits from non-disabled viewers, to create a more inclusive society. A qualitative research approach is employed to gain a better understanding of a specific phenomenon. The specific phenomenon was the representation of wheelchair disability identities, and to untangle this, three research approaches were used, namely autoethnography, case studies and participatory design. A total of 10 wheelchair-disabled persons, from Cheshire Home Summerstrand in Gqeberha participated in the study. It was found that by involving participants in the practical development process, more positive illustrations of disability representation can be produced, allowing for clearer communication of the disability identity. The responses to the interview questions confirmed that people with disabilities believe that non-disabled people have misconceptions about the disability identity. The research thus aims to challenge these misconceptions and motivate more positive interpretations and understanding of the disability identity through visual communication. , Thesis (MVA) -- Faculty of Humanities, School of Visual and Performing Arts, 2024

- Description: With the rise in popularity of electric vehicles and portable electronic devices, having a reliable, lightweight, and long-lasting battery is crucial. This has led to the mass commercialisation of lithium-ion batteries (LIB’s) because they offer several advantages over other battery technologies. Over the years, one of the concerns was with the ease with which the batteries can burn or explode when subjected to certain extreme conditions. In order to build trust in these products and to expand the technology into more diverse applications, safety aspects of the batteries has become of widespread concern resulting in a key area of research. One aspect of improving the safety is by reducing the flammability of the battery by the addition of certain chemicals that stop or suppress the thermal runaway effect. However, this in-turn reduces the battery’s capacity and life-cycle performance. Researchers have used the idea of encapsulating these chemicals thereby physically separating them within the lithium-ion battery (LIB) electrolyte system with a minimum effect on performance. This research aims to explore use of R-diols and R-amines as additives that upon a thermal trigger would react with the lithium-ion battery electrolyte to stop the effect of the thermal runaway by forming carbamate derivatives which are gel-like or form solid aggregates. The R-diols or R-amines can react with electrolyte at higher temperatures with the lithium-hexafluorophosphate acting as a catalyst. This change in the physical state of the electrolyte increases the resistance inside the battery which then hinders ion movement and forms a physical barrier to reduce the effect of short circuiting when the separator or other components are damaged due to higher temperatures. , Thesis (MSc) -- Faculty of Science, School of Biomolecular & Chemical Sciences, 2024

- Description: This study examines the effect of the alcohol ban from 2020 to 2021 on consumer preferences and consumption habits. The COVID-19 virus was first detected in China, in 2019. The virus spread rapidly, crippling health care systems across the world. As the disease spread, countries began looking at ways to reduce the strain on the health care system caused by other factors (Gu, 2020). The first case in South Africa was recorded on 5 March 2020. South Africa reacted quickly and decided to implement a hard lockdown on alcohol, 22 days after the first case was recorded (Murhula & Nunlall, 2021). Due to the high number of trauma-related cases, which affected the healthcare system and South Africa’s reputation for being a country that consumes high volumes of alcohol, the government needed swift action. This alcohol ban sent shock waves across the country and alcohol consumers began to panic (BBC, 2020). In addition, the alcohol ban caused people to alter their consumption behaviours and some even resorted to homebrewing alcohol during the lockdown. Alcohol was available through the illicit market, which came at a premium price with limited options. This study originated from the alcohol ban, as consumers were exposed to brands, they otherwise would not have considered if all alcohol beverages were available. The scarcity of alcohol products, the excessive prices of alcohol and the effort it took to obtain alcohol, played a major role in altering drinking behaviours and brand preferences post the alcohol ban. Results from the study indicated that age and gender played no significant role in alcohol consumption, brand preference across categories were affected with two of nine alcohol categories experiencing a decline in consumption, from before to after the ban. During the ban, the majority of respondents consumed alcohol with some resorting to homebrewed alcohol, which showed a significant increase in consumption during the ban. The opportunity to further this study would be to investigate the increase in low alcoholic beverages and non-alcohol beverages as key avenues for organisations within the alcohol industry. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2024

- Description: Economic diversification has been at the forefront of many countries’ socio-economic development agendas, especially resource-rich developing countries. It is seen as a tool for attaining socio-economic development. After independence as a strategy to resolve socio-economic challenges, most developing economies like Namibia implemented policies and strategies enabling economic diversification. This study provides an empirical analysis of Namibia’s economic diversification and socio-economic development between 1990 and 2021. The study used a concurrent mixed research methodology involving quantitative secondary and qualitative interview-based primary data to assist in filling any gaps left by either methodology. The interviews helped expand and validate the secondary data results. The quantitative component of the study focuses on determining the level of economic diversification, the drivers of that diversification and the effect of economic diversification on socio-economic development. The study used the Tress and Ogive indices to proxy for economic diversification, while employment, poverty reduction and economic growth represent socio-economic development. Reading from these economic diversification measures, Namibia’s economy is relatively diversified but remains in the initial stage, with Tress and Ogive indices levels of 48.09/6.03. The study also found that in the long run, foreign direct investment (FDI), education and institutional quality lead to increased economic diversification while inflation discourage economic diversification. In the short run, FDI and education enhances diversification while inflation, financial sector development and earnings from natural resources lead to a decline in economic diversification. In examining the effect of economic diversification on socio-economic development, the results show that it has a positive influence on employment creation, poverty reduction and economic growth in the long and the short term. So overall the study found that economic diversification contributes positively to socio-economic development. To validate the quantitative results, six senior executives from five entities which includes ministries, government agencies and the private sector were selected purposively for interviews on their perception of economic diversification in Namibia and the data were analysed thematically. The results were inconclusive with regard to the effectiveness of the enabling policies. The participants agreed the enabling policies had contributed to employment, poverty reduction, income equality and economic growth. However, more needs to be done, like creating value chain-connected sectors that create seasonal employment, for the contribution to be sustainable. The study also found that the cost of doing business (mainly taxation and the cost of water and electricity); policies and institutional frameworks (like immigration, trade and investment laws); competitiveness of the economy in terms of its size, quality of human capital, manufacturing capacity and economic uncertainty are the leading challenges affecting the progress of Namibia’s economic diversification process. This researcher drew up several recommendations for the Namibian government to continue enhancing economic diversification to address the socio-economic challenges of unemployment, poverty and income inequality through investment in productive areas of the manufacturing and services sectors which can contribute to growth and employment. The government also needs to address the challenges hindering the progress of economic diversification in the country to create an environment that can foster economic diversification. The study recommends targeted intervention to enhance the attractiveness of other sectors so as to wean the economy off its high dependence on the primary sector through the provision of both fiscal and non-fiscal incentives. The required human capital development should be harnessed through investment in capabilities like vocational skills that are needed for economic diversification and socio-economic development to be achieved. Good governance should be attained by fighting corruption to enhance investment confidence.

- Description: Economic diversification has been at the forefront of many countries’ socio-economic development agendas, especially resource-rich developing countries. It is seen as a tool for attaining socio-economic development. After independence as a strategy to resolve socio-economic challenges, most developing economies like Namibia implemented policies and strategies enabling economic diversification. This study provides an empirical analysis of Namibia’s economic diversification and socio-economic development between 1990 and 2021. The study used a concurrent mixed research methodology involving quantitative secondary and qualitative interview-based primary data to assist in filling any gaps left by either methodology. The interviews helped expand and validate the secondary data results. The quantitative component of the study focuses on determining the level of economic diversification, the drivers of that diversification and the effect of economic diversification on socio-economic development. The study used the Tress and Ogive indices to proxy for economic diversification, while employment, poverty reduction and economic growth represent socio-economic development. Reading from these economic diversification measures, Namibia’s economy is relatively diversified but remains in the initial stage, with Tress and Ogive indices levels of 48.09/6.03. The study also found that in the long run, foreign direct investment (FDI), education and institutional quality lead to increased economic diversification while inflation discourage economic diversification. In the short run, FDI and education enhances diversification while inflation, financial sector development and earnings from natural resources lead to a decline in economic diversification. In examining the effect of economic diversification on socio-economic development, the results show that it has a positive influence on employment creation, poverty reduction and economic growth in the long and the short term. So overall the study found that economic diversification contributes positively to socio-economic development. To validate the quantitative results, six senior executives from five entities which includes ministries, government agencies and the private sector were selected purposively for interviews on their perception of economic diversification in Namibia and the data were analysed thematically. The results were inconclusive with regard to the effectiveness of the enabling policies. The participants agreed the enabling policies had contributed to employment, poverty reduction, income equality and economic growth. However, more needs to be done, like creating value chain-connected sectors that create seasonal employment, for the contribution to be sustainable. The study also found that the cost of doing business (mainly taxation and the cost of water and electricity); policies and institutional frameworks (like immigration, trade and investment laws); competitiveness of the economy in terms of its size, quality of human capital, manufacturing capacity and economic uncertainty are the leading challenges affecting the progress of Namibia’s economic diversification process. This researcher drew up several recommendations for the Namibian government to continue enhancing economic diversification to address the socio-economic challenges of unemployment, poverty and income inequality through investment in productive areas of the manufacturing and services sectors which can contribute to growth and employment. The government also needs to address the challenges hindering the progress of economic diversification in the country to create an environment that can foster economic diversification. The study recommends targeted intervention to enhance the attractiveness of other sectors so as to wean the economy off its high dependence on the primary sector through the provision of both fiscal and non-fiscal incentives. The required human capital development should be harnessed through investment in capabilities like vocational skills that are needed for economic diversification and socio-economic development to be achieved. Good governance should be attained by fighting corruption to enhance investment confidence. It further recommends that Namibia ratifies and implement the SADC protocol on trade and the African Continental Free Trade Area (AfCFTA) agreement to increase market accessibility and address the country’s market size, which is currently uncompetitive for investment. , Thesis (PhD) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 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
