- Description: Employee engagement is a critical aspect of organisational success, and with the increasing adoption of flexible working arrangements (FWAs), understanding its determinants becomes crucial. However, many organisations are struggling to keep employees engaged while offering them flexible working patterns. Therefore, this study aimed to determine the factors that influence employee engagement among employees of the Road Accident Fund (RAF) in South Africa after the introduction of flexible working arrangements. To achieve the main aim of this study, a literature study was undertaken on employee engagement and a flexible working environment. The main focus of the literature study was to determine the factors with the most potential to influence employee engagement in the context of a flexible working environment. These factors emerged as work-life balance, employee wellbeing, leadership, rewards and recognition, learning and development, employee involvement, effective communication and workplace flexibility. This led to conducting an empirical study utilising a self-administered online survey as the data collection instrument to determine the influence of these factors on the engagement of RAF employees. A scale was developed to determine these factors and the current engagement level of employees at the RAF was measured using the Utrecht Work Engagement Scale (UWES) (2002). A descriptive and correlational research design was employed, utilising a convenience sampling method with a final sample of 413 achieved. Data was analysed using descriptive and inferential techniques, including Cronbach’s Alpha, frequency distributions, measure of central tendencies and exploratory factor analysis (EFA), product moment correlation, t-tests, analysis of variance (ANOVA) and chi-square tests. This included the testing for potential relationships between the variables of interest.The results of the empirical study revealed some of factors that were identified in the literature review of this study were found to have a positive influence on the engagement of employees working in the flexible working environment offered by the RAF. These factors are employee well-being, leadership, reward and recognition, learning and development, employee involvement, effective communication and workplace flexibility (time). The factors that were excluded by the results were work-life balance and workplace flexibility (place). These exceptions imply that these factors have less influence on the overall employee engagement levels at the RAF. Moreover, the levels of engagement of RAF employees were found to be at a moderate level. Furthermore, the results indicated that regardless of whether employees utilised FWAs or not, their levels of engagement remained at a moderate level. In other words, the utilisation of FWAs did not appear to significantly impact on the overall engagement levels of employees, and both groups exhibited similar moderate engagement levels. The findings also suggest that the RAF should maintain and enhance the factors that have a positive influence on employee engagement. In addition, the organisation should work on addressing those factors that do not play as significant a role in influencing engagement as the other factors. By taking these steps, the RAF can effectively enhance the overall level of employee engagement among its workforce. , Thesis (MCom) -- Faculty of Business and Economic Sciences, School of Industrial Psychology and Human Resources, 2023

- Description: Geological mapping in the Lesotho-Drakensberg Mountains spans over 100 years with du Toit and Stockley being the major contributors to the published maps and to the understanding of emplacement of the Karoo Large Igneous Province (KLIP) in the countries of South Africa and Lesotho. Despite the detailed previous work, there remains limited data on paleoenvironmental changes at the contact between the sedimentary and volcanic sequences of the upper Karoo Supergroup. This study aims to map the lithostratigraphic boundaries, volcano-sedimentary facies and faults near Ha Mosi in southern Lesotho. A total 48 rock samples were collected for petrography, XRF and ICP-MS analyses. The new results were used to characterize the local chemostratigraphy and to propose new regional correlations across Lesotho and South Africa. In this thesis, eight lithostratigraphic units were defined with a total thickness of 550 m. The first two units (Units 1 and 2) comprise massive and bedded sandstones, interpreted as possible floodplain and ephemeral lacustrine deposits; these are ascribed to the upper Stormberg Group. These units are unconformably overlain by locally preserved thin basaltic (Unit 3) flows that are characterised by high Zr/Nb and Zr/Y ratios; and low Ti/Zr and P/Zr ratios similar to the Golden Gate Unit of the Drakensberg Group. The lava flows are overlain by bedded sandstone ascribed to Unit 4 and volcaniclastic breccia ascribed to Units 5 and 6. Unit 6 consists of a monolithic breccia that is composed of angular sandstone clasts similar to those of the underlying Stormberg Group. The monolithic breccia transitions upwards into a massive megaclastic clast-supported volcanic breccia, which consists of angular to sub-rounded basaltic and doleritic boulders. Petrified wood fragments are found within the megaclastic breccia, indicating the presence of vegetation during deposition and enhanced preservation. Unit 6 laterally grades into Unit 5, which is characterised by poorly bedded breccia composed of angular sandstone, mudstone clasts with minor basaltic and doleritic clasts and, breccia intraclasts. The breccia units are often associated with reworked sediments interpreted to be deposited by fluvial systems. The breccia is conformably overlain by basaltic lava flows (Unit 8) characterised by high Ti/Zr and P/Zr ratios and moderate to low Zr/Y and Zr/Nb ratios compared to the Unit 3 lavas and is similar to that of the Sani Pass Unit of the Drakensberg Group. The basaltic sequences in the Ha Mosi studied area preserve both pahoehoe textures and pillow lavas, indicating subaerial and subaqueous volcanism. The studied lithologies are intruded by gabbro and dolerites of the Karoo Dolerite Suite at 183 Ma. This stratigraphy records the transition from sedimentation in the Karoo Basin through to a dominantly volcanic succession, which has importance in terms of the Toarcian extinction at ca. 182 Ma. Mapped faults and associated fractures are orientated predominantly NW-SE with the hanging walls moved maximum 80 m to the south. The different dykes and fault structures possibly relate to the Weddel Triple Junction that developed during the Early Jurassic break up of Gondwana, between 200 and 180 Ma. The mapped lavas show that the magma source was a chemically heterogenous mantle that was subjected to different degrees of partial melting, with the introduction of small-scale chemical heterogeneities. The geodynamic setting is comparable to the Afar Triangle of north-east Africa where active tectonics created a large-scale NW-SE orientated fault system in response to crustal thinning and rifting. In both the Afar and Lesotho, vertical movements created lowlands that allow for the preservation of volcanic breccia and basalts with pillow lavas. These findings show that existing geological models in the Drakensberg-Lesotho Mountains can be improved upon detailed field mapping and geochemistry. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2023

- Description: Financial deepening and economic growth have received much attention in the literature. However, there remains a significant gap in understanding the relationship between financial deepening, and bank performance especially within the context of South African commercial banks. This research aims to investigate the empirical relationship between financial deepening and the performance of all South African commercial banks from 1987 to 2019. The research adopts a descriptive research design and utilizes secondary data along with time series analysis techniques. The research empirically investigates the relationship between financial deepening and bank performance, using financial deepening indicators such as Market Capitalisation (MC), Credit to the private sector (CR), Money Stock (MS), and Bank liquidity (BL). Control variables such as Gross Domestic Product (GDP), Inflation rate (IF), and Lending interest rate (LR) are also considered. The autoregressive distributed lag bounds testing (ARDL) method is employed to test the relationship between financial deepening and bank performance. The autoregressive distributed lag bounds testing (ARDL) method is employed to test the relationship between financial deepening and bank performance of South African commercial banks. The findings indicate that financial deepening has both short-term and long-term impacts on bank performance. Each component of the financial deepening indicators demonstrates a strong and statistically significant relationship with bank performance. This empirical evidence suggests that financial deepening has made a positive contribution to the profitability of South African commercial banks. Furthermore, the analysis reveals a long-run equilibrium relationship between financial deepening and the economic performance of the South African banking sector. This research addresses the gap between theoretical beliefs and empirical evidence by establishing a robust and positive contribution of financial deepening to the profitability of South African commercial banks. The findings highlight the significance of financial deepening in enhancing bank performance in South Africa. , Thesis (MCom) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 2023

- Description: In this thesis, we constructed some versions of finite difference scheme for the Burgers-Huxley equation and for a set of partial differential equations (PDEs) arising in biofilm formation. The Burgers-Huxley equation serves as a fundamental model that describes the interaction between reaction mechanisms, convection effects, and diffusion transport. It has applications in the study of wave mechanics, population dynamics, physiology, fluid mechanics to list but a few. The study of biofilm formation is becoming increasingly important due to micro-organisms (i.e. bacteria) forming a protected mode from the host defense mechanism which may result in alteration in the host gene transcription and growth rate. Applications can be found useful in the treatment of bacterial infections, contamination of foods and water quality. We designed two nonstandard finite difference and two exponential finite difference schemes for the Burgers-Huxley equation. Numerical experiments with six cases and in three different regimes were studied. We show that the nonstandard scheme preserves the properties of the continuous equation which include positivity and boundedness. The stability region of the explicit exponential scheme was obtained and we outlined the algorithm for the implicit exponential scheme. The performance of the four schemes are compared in regard to absolute error, relative error, L1 and L∞ norms. For a singularly perturbed Burgers-Huxley equation, a novel nonstandard finite difference technique is constructed. It is demonstrated numerically that the NSFD scheme outperforms the classical scheme by comparing maximum pointwise errors and rate of convergence. We then solved the 2D Burgers-Huxley equation using four novel nonstandard finite difference schemes (NSFD1, NSFD2, NSFD3 and NSFD4). The numerical profiles from NSFD1 and NSFD2 exhibit some deviation from the exact profile. Our quest for a better performing scheme led to the modification of NSFD1 using the remainder effect technique. NSFD4 was designed by employing the time splitting approach. All the schemes preserve the properties of the continuous model (positivity and boundedness). The performance of all the schemes are analysed. We construct three nonstandard finite difference schemes for the equations modelling biomass equation and coupled substrate-biomass system of equations respectively. We checked the accuracy of our scheme by the conservation of physical properties (positivity, boundedness, biofilm formation and annihilation) since an analytical solution is not available. We show the instability, lack of conservation of physical properties by the classical scheme. Our proposed scheme shows good performance when compared with other results in the literature. The results here give more insight into the benefits of the nonstandard finite difference approximations. , Thesis (DPhil) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics , 2023

- Description: This treatise presents the formulation of an operational efficient strategy for the National Health Laboratory Services (NHLS) in the Eastern Cape. Operational inefficiency in the NHLS has the potential to delay laboratory results delivery for necessary health intervention, which may have a negative impact on individuals’ health or lead to death. The aim of the study is to highlight inadequacies that may cause poor service delivery and formulate an operational plan for the NHLS in the Eastern Cape. Strategic efficiency is derived from the resource-based and agent theories. Even though there is a difference between service and manufacturing industries, the operational strategic framework can be used in both. A strategic framework is implemented by assessing market requirements and using the top-down or bottom-up approach. To monitor and regulate these strategies, one can utilise, among others, scorecards, corporate social responsibility and risk management. This is a qualitative research study using semi-structured interviews to gather information from 11 participants. The study targeted managers in the NHLS Eastern Cape region, with a non-probability method, as the large number of managers in the entire region made it impossible to do a random study. Furthermore, the data were analysed by the thematic analysis method. The literature review identified six factors that influence public sector efficiency, namely, compliance issues, ethics, financial expense management, resource optimisation, accountability and service delivery. The primary study revealed several inadequacies in the NHLS Eastern Cape, namely, inefficient human resources practices, underutilising technology, ambiguous policies, delayed turnaround time, lack of financial training for management and lack of support from cross-functional departments. In addition, the results of the study warrant the following recommendations: Proper orientation of staff, with modules pertaining not only to their duties and reporting structure but also to the policies of the organisations and conduct; SWOT analyses and surveys could also be used to assess internal staff and external factors that may hinder efficiency; the installation of solar panels for laboratories, starting with the vulnerable labs in remote , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2023

- Description: Offshore benthic ecosystems (> 200 m depth) are challenging to access and remain poorly studied globally. Epifaunal invertebrates comprise a critical trophic level in benthic ecosystems and can serve as indicators of the overall health and functioning. There is limited knowledge of South Africa’s offshore marine environment and benthic ecosystem functioning due to limitations in funding, resources, and the lack of suitable science-based monitoring tools which are vital for sustainable management into the future. The aim of this research was to improve the understanding of epifaunal functioning as well as their potential physical drivers in 13 South African offshore biogeographic ecotypes. The objectives of this study were threefold: 1) to investigate the functional composition of benthic epifauna from 13 biogeographic ecotypes, 2) to quantify the Functional Diversity (FD) associated with epifaunal traits between the different assemblages (i.e. biogeographic ecotypes), and 3) to evaluate the relationship between physical variables and epifaunal functional traits at the biogeographic ecotype level. Biological trait-based approaches were applied to a subset of 80 benthic epifaunal species collected from 909 offshore stations along the west and south coasts of South Africa. Nine biological traits (associated with life history, morphology and behavioural characteristics exhibited by each species) were classified into 39 modalities and weighted with biomass. Community Weighted Means (CWMs) were used to evaluate the benthic epifaunal functional trait composition of the 13 biogeographic ecotypes. Functional composition across the 13 ecotype assemblages on the west and south coast appeared to be dominated by species with similar trait compositions, such as large, long-lived, surface crawling/burrowing/filter-feeding epifauna with medium to no mobility, however, their percentage of contribution to trait expression (CWMs) was higher on the west coast. Functional diversity indices (alpha and beta) showed higher overall FD for west coast ecotypes, with most ecotypes on the continental shelf (except slopes and canyons) being significantly different (p<0.05) from ecotypes on the south coast. The global RLQ (three-table co-inertia) test did not reveal a significant relationship between biomass and physical variables or between biomass and traits (p>0.05). The fourth-corner method was used to test the significance of individual traitenvironment relationships. The fourth-corner results were similar overall to the RLQ analysis, revealing that three physical variables (temperature, depth, and fluorescence) were significantly correlated to two trait modalities belonging to the feeding mode filter-feeders (FM1) and scavengers (FM5). Scavengers were positively correlated with depth and negatively with temperature, while filter-feeders were positively correlated with fluorescence levels. This indicated that the presence of scavenging epifauna increased with a decrease in temperature and an increase in depth. While a positive significant correlation between filter-feeders and fluorescence suggested their potential tolerance or preference for environmental conditions with high levels of fluorescence. This research was the first such study to explore the functional composition and diversity of benthic epifauna and their relationship with potential physical drivers in offshore west and south coast benthic biogeographic ecotypes of South Africa. The application of new tools to quantify the functional diversity of epifauna as indicators of ecosystem health, and their potential physical drivers. This provided a platform on which to advance our understanding of benthic communities and the roles they play in ecosystem functioning under changing environments.

- Description: Offshore benthic ecosystems (> 200 m depth) are challenging to access and remain poorly studied globally. Epifaunal invertebrates comprise a critical trophic level in benthic ecosystems and can serve as indicators of the overall health and functioning. There is limited knowledge of South Africa’s offshore marine environment and benthic ecosystem functioning due to limitations in funding, resources, and the lack of suitable science-based monitoring tools which are vital for sustainable management into the future. The aim of this research was to improve the understanding of epifaunal functioning as well as their potential physical drivers in 13 South African offshore biogeographic ecotypes. The objectives of this study were threefold: 1) to investigate the functional composition of benthic epifauna from 13 biogeographic ecotypes, 2) to quantify the Functional Diversity (FD) associated with epifaunal traits between the different assemblages (i.e. biogeographic ecotypes), and 3) to evaluate the relationship between physical variables and epifaunal functional traits at the biogeographic ecotype level. Biological trait-based approaches were applied to a subset of 80 benthic epifaunal species collected from 909 offshore stations along the west and south coasts of South Africa. Nine biological traits (associated with life history, morphology and behavioural characteristics exhibited by each species) were classified into 39 modalities and weighted with biomass. Community Weighted Means (CWMs) were used to evaluate the benthic epifaunal functional trait composition of the 13 biogeographic ecotypes. Functional composition across the 13 ecotype assemblages on the west and south coast appeared to be dominated by species with similar trait compositions, such as large, long-lived, surface crawling/burrowing/filter-feeding epifauna with medium to no mobility, however, their percentage of contribution to trait expression (CWMs) was higher on the west coast. Functional diversity indices (alpha and beta) showed higher overall FD for west coast ecotypes, with most ecotypes on the continental shelf (except slopes and canyons) being significantly different (p<0.05) from ecotypes on the south coast. The global RLQ (three-table co-inertia) test did not reveal a significant relationship between biomass and physical variables or between biomass and traits (p>0.05). The fourth-corner method was used to test the significance of individual traitenvironment relationships. The fourth-corner results were similar overall to the RLQ analysis, revealing that three physical variables (temperature, depth, and fluorescence) were significantly correlated to two trait modalities belonging to the feeding mode filter-feeders (FM1) and scavengers (FM5). Scavengers were positively correlated with depth and negatively with temperature, while filter-feeders were positively correlated with fluorescence levels. This indicated that the presence of scavenging epifauna increased with a decrease in temperature and an increase in depth. While a positive significant correlation between filter-feeders and fluorescence suggested their potential tolerance or preference for environmental conditions with high levels of fluorescence. This research was the first such study to explore the functional composition and diversity of benthic epifauna and their relationship with potential physical drivers in offshore west and south coast benthic biogeographic ecotypes of South Africa. The application of new tools to quantify the functional diversity of epifauna as indicators of ecosystem health, and their potential physical drivers. This provided a platform on which to advance our understanding of benthic communities and the roles they play in ecosystem functioning under changing environments. Functional trait-based approaches such as those applied in this study can provide us with vital information on the relationship between biodiversity, ecosystem functioning, and physical drivers. Environmental stressors and changing climate patterns threaten to impact marine ecosystems and their functioning. Benthic epifauna are especially sensitive to changes in their environment and these fluctuations could potentially lead to the loss of certain benthic functionality, altering the thresholds these ecosystems have to response to disturbances. This undermines the stability of these ecosystems which can have ripple effects on the health of these ecosystems and their ability to provide the ecosystem services humans dependent on.

- Description: Honouring the dead is upheld in religions and cultures across the world and embedded in rituals and rites of passage that must be adhered to. In many instances, religio-cultural beliefs synthesise or overlap, creating a mutual influence on the person. These religio-cultural rituals are symbolic and important for the living, but they are also equally important for the dead in order to ensure that their souls are returned to the source of their belief system. The COVID-19 lockdown restrictions in South Africa altered death ceremonies and rituals by limiting social gatherings to 50 people to ensure safety protocols like mask wearing and physical distancing. Additionally, family members were prohibited from interacting with the deceased’s body, including performing rituals like washing and dressing, to prevent virus spread. The resultant psychological consequences of these changes to burial practices have not been fully explored in the South African context, and given the importance rituals play, it becomes important to understand them. Studying the psychological consequences of the changes provided insights into individuals’ grief and loss coping in the absence of traditional burial rituals and practices. This is aimed at assisting with the development of interventions for mental health and well-being in future crises. The study explored the psychological consequences of COVID-19 lockdown restrictions on AmaXhosa burial practices and rituals in the Eastern Cape Province of South Africa. AmaXhosa have a rich cultural heritage that places great significance on death and burial rituals. These rituals serve as a way to honour and remember the deceased, provide closure for the bereaved, and maintain social cohesion within the community. The absence of these rituals during the COVID-19 lockdown had consequences for the AmaXhosa’s psychological and religio-cultural well-being. The exploration of their experiences was thus important because it shed light on the importance of these rituals and will help devise innovative ways to address their psychological needs during times of loss. The study utilised a qualitative method, conducting interviews with AmaXhosa aged 18 and older. Participants , Thesis (PhD) -- Faculty of Health Science, 2023

- Description: This research study came about as a result of healthcare failures and underperformance at the Eastern Cape Department of Health, causing procurement delays. Procurement is central to the government service delivery system as it promotes goals that are secondary to the primary aim of procurement, such as using procurement to promote social, industrial, or environmental policies. The ultimate goal of the study was to research the root cause for procurement delays and how improvements can be brought about through studying procurement industry trends. The critical step to resolve bottlenecks in the procurement system is to investigate the root cause. Six causes of procurement delays emerged from the literature due to: (1) procurement staff, (2) procurement irregularities, (3) poor budget planning and demand forecasting, (4) poor communication, (5) procurement structure, and, (6) manual systems used for procurement transactions. Guided by these causes of procurement delays, the researcher developed a questionnaire to understand the cause of delays at the Eastern Cape Department of Health. An interpretivism research paradigm (quantitative) was selected to analyze research on best practices. The researcher distributed questionnaires as a method for collecting data from the identified sample size of 90. The purpose of the questionnaire was to validate the data collected during the literature review. Out of the distributed sample, 69 responses were received and used for analysis, thus representing a 74% response rate, which is considered acceptable. The researcher used descriptive analysis to interpret data. The study's key findings indicated that ECDOH employees had been fairly trained on the SCM policies within the department. However, there is a concerning representation of 40,6% of employees who have not been provided with training, which could impact responsiveness to the procurement process. The study further revealed that 85,5% of employees understood the impact of procurement delays due to irregular expenditure (an Auditor General repeat finding for the ECDOH). , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2023

- Description: Immigration remains an issue of constant and recuring debate which in many instances has reached extreme limits of violent confrontation. South Africa has been at the forefront of this debate given the history of migration that has led to the creation of the modern state. In this context, the current era has presented contestations on the implications of immigration to the country and how that relates to human development. With this backdrop, this thesis sought to investigate international immigration and its relation to human development outcomes within context of the democratic era in South Africa. Thus, the study focused on evaluating the differences between immigrants and non-immigrants in terms of physical and mental health, subjective wellbeing, and education. Furthermore, the study evaluated the relationship between immigration concentration across provinces and human development outcomes in aggregate. The comprehensive results focusing on both the full and racial specific sample identified that there are no significant differences between immigrants and non-immigrants in terms of health pinned to self-reported health. This finding supports small scale studies in South Africa and other countries which divert from the immigrant-paradox paradigm although this could be accounted for by convergence adjustments to the healthy immigrant effect. In terms of mental health and subjective wellbeing, the results showed that immigrants are significantly less likely to report depressive level scores on the CEDS-10 scale. Thus, the study demonstrated that the healthy immigrant effect holds in relation to depression. Contrarily, in terms of satisfaction with life, no significant differences are found between immigrants and non-immigrants, thus pointing to possible sudden convergence upwards in satisfaction with life, particularly considering most immigrants are from countries with lower levels of satisfaction with life. In relation to education findings, it was demonstrated that there are no significant differences between immigrant and non-immigrant students in terms of progression. Thus, neither the straight-line nor immigrant-paradox argument prevails as found mostly in the Global North. Lastly, regional analysis which accounted for human development across provinces showed that a significant positive relationship exists between immigration concentration and human development overall coupled with the component accounting for education diverting from panel studies. Furthermore, insignificant relationship is found in terms of health and income supporting findings by the study of no differences between immigrants and non-immigrants. Thus, this thesis proved that the pessimistic view on immigrants significantly diverting from the overall health and education levels coupled with negative relationship with human development are not supported empirically within the context of post-apartheid South Africa. Results of this study provide evidence that is critical to formulate policy, both in terms of immigration and further factors identified as important markers, on issues of education and physical and mental health such as race, gender, and wealth. In this regard, the differences in findings from those in countries especially in Global North challenge policies based on theoretical and empirical formulations that lack account for countries especially in the Global South which have increased levels of both inequality and poverty. Thus, it is critical that policies reflect the socioeconomic issues a country faces and informed by research that takes regional factors within a country to account. The study prescribes policies which aim to reduce discrimination due to unproved assumptions and those that aim to ensure that racial and income inequality are tackled within the country. In terms of immigration, rollout of awareness projects and campaigns, coupled with regional policies and projects rooted in communities to ensure participation of both sending and receiving countries will create platforms for better structuring of policies to tackle immigration especially given the integration goals of the African Union. Moreover, critical revaluation of policies and implementation thereof is critical given results identify inequality with those that are African, Coloured, and from poorer households facing lower levels of health, education and high levels of depression scores coupled with life dissatisfaction. Policies should thus, focus on ensuring that redistributive investments are enabled and implemented efficiently for better outcomes in terms of access to education, health, and economic opportunities for the disadvantaged. In enabling such projects with considerations of societal needs and immigration policies, strides could be made given that most contestations arise out of increased inequalities and socioeconomic destitution. , Thesis (PhD) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 2023

- Description: The heightened competition for skilled students, capable staff, and government funding has spurred Zimbabwean higher education institutions to engage in competitive efforts. Due to the intense competition in the higher education sector, higher education institutions have become more market-oriented than before. Furthermore, the increased offering of online programmes by higher education institutions during the COVID-19 pandemic period has increased the bargaining power of students. Higher education institutions have therefore taken initiatives to promote their institutions through various interactive digital marketing activities. Digital marketing activities have brought about innovative changes and opportunities for higher education marketers. Higher education marketers, specifically university marketers, are taking advantage of the opportunity to market their institutions through digital marketing activities, thereby gaining a competitive advantage over other institutions of higher education such as polytechnics. There is, therefore, a need for polytechnics to effectively utilise digital marketing activities such as websites, text messaging, social media marketing and email marketing for brand awareness purposes so that they gain a competitive advantage over other institutions of higher learning. The study aimed to empirically evaluate the influence of digital marketing activities on brand awareness of Zimbabwe polytechnics and to propose a model that can be adopted by Zimbabwean polytechnics in an attempt to enhance their brand awareness. As such, a conceptual model was constructed from the literature review to investigate the relationship between digital marketing activities (independent variable) and brand awareness (dependent variable). Based on the comprehensive literature review, four digital marketing activities (website, text messaging, social media marketing and email marketing) were identified in the Zimbabwean polytechnic context. The study further identified the digital marketing activities sub-factors that were adopted in the development of a customised measuring instrument that was used to evaluate the influence of digital marketing activities on brand awareness of Zimbabwean polytechnics. These sub-factors included web design, navigation, interactivity and relevance for website; personalisation, interactivity, timeliness and reliability for text messaging; interactivity, sharing of content, advocacy and credibility for social media marketing and personalisation, interest, informativeness, interactivity and efficiency for email marketing. Furthermore, five hypotheses were formulated and three hypotheses were supported while two hypotheses were rejected. The positivist paradigm, the descriptive research design and the quantitative approach were used in the current study. The study‟s target population consisted of the registered student population of the two Zimbabwean polytechnics in the Midlands province, in the Applied Sciences, Commerce and Engineering divisions. The respondents were selected using non-probability sampling, specifically convenience sampling. Data was collected through an email survey, whereby a web-based self-administered questionnaire was distributed to the Applied Sciences, Commerce and Engineering students with assistance from the Information Technology Departments of the two polytechnics. The measuring instrument consisted of three sections with section A having nominal scales to gather demographic data from respondents. Section B consisted of scaled items that measured the influence of digital marketing activities, while section C measured brand awareness focussing on the three levels of brand awareness. A total of 500 completed questionnaires were received from the two polytechnics. Out of the 500 completed questionnaires, a total of 492 questionnaires had usable responses. Therefore, the current study had a response rate of 98.4%. The study further used descriptive statistics and inferential statistics to interpret the data. The descriptive statistics utilised included frequency measures of central tendency and measures of dispersion or variation. Regarding inferential statistics, the study utilised the CFA, Pearson‟s correlation coefficient, regression analysis, p-value independent sample t-test, ANOVAs and the Welch Robust test, Tukey HSD test, the Games-Howell test and the Cohen‟s d tests. The findings of the study revealed a significant relationship and a strong correlation between digital marketing activities and brand awareness. Regarding website use and brand awareness, a significant relationship and a moderate correlation were determined. The results further revealed an insignificant relationship but a moderate correlation between text messaging and brand awareness. The empirical results also revealed a significant relationship and a strong correlation between social media marketing and brand awareness. Finally, an insignificant relationship and a moderate correlation were revealed between email marketing and brand awareness in the current study. Based on the empirical results, this study gave recommendations to polytechnic marketers. Under the website use items, the study revealed that the respondents had a less positive experience with the web design of the polytechnics' websites. It was recommended that polytechnic marketers should take pragmatic steps to enhance their polytechnic web designs so that students can take note of the college information on well-organised polytechnic websites. The study also found that the respondents felt the need to experience more personalisation and timeliness of the polytechnics' text messaging. Therefore the polytechnic marketers were advised to personalise their text messages each time that they send them to students enabling them to build long-lasting relationships with students. Regarding the timeliness of text messaging, the polytechnic marketers were advised to send text messages to students at the right time when they need the information so that the disseminated information is readily accepted by the students. The polytechnic marketers were also advised to provide up-to-date polytechnic information on their social media pages after the respondents indicated the need to experience more sharing of content on the colleges' social media pages through the provision of up-to-date information. Lastly, the empirical results revealed that the respondents felt the need to experience more personalisation and the provision of interesting content through polytechnic email marketing. Therefore the Zimbabwean polytechnic marketers were strongly recommended to personalise the students' emails to motivate students to engage with them personally. The polytechnic marketers were further recommended to include interesting content in students' emails so that they draw the students' attention to polytechnic information in their emails. The study made the following important contributions. Firstly, the study made contributions to theory, literature, knowledge, society and marketing practitioners within the context of digital marketing activities and brand awareness in Zimbabwean polytechnics. Secondly, the current study provided the measuring instrument and a model that adds to scholarly work and provides a basis for future research in the marketing of Zimbabwean polytechnics. Thirdly, the study will assist in the enhancement of brand awareness of Zimbabwean polytechnics, enabling them to attract academically gifted students who will become productive workers, self-reliant entrepreneurs and responsible citizens. Lastly, the model will also provide a basis for future reference for polytechnic marketers in their marketing efforts for competitive advantage purposes. The current study had limitations that comprised uneven sample distribution, the adoption of limited social media variables and the exclusion of external stakeholders from the current study. Finally, the study made recommendations for future areas of study. , Thesis (PhD) -- Faculty of Business and Economic Sciences, School of Management Sciences, 2023

The study further identified the digital marketing activities sub-factors that were adopted in the development of a customised measuring instrument that was used to evaluate the influence of digital marketing activities on brand awareness of Zimbabwean polytechnics. These sub-factors included web design, navigation, interactivity and relevance for website; personalisation, interactivity, timeliness and reliability for text messaging; interactivity, sharing of content, advocacy and credibility for social media marketing and personalisation, interest, informativeness, interactivity and efficiency for email marketing. Furthermore, five hypotheses were formulated and three hypotheses were supported while two hypotheses were rejected. The positivist paradigm, the descriptive research design and the quantitative approach were used in the current study. The study‟s target population consisted of the registered student population of the two Zimbabwean polytechnics in the Midlands province, in the Applied Sciences, Commerce and Engineering divisions. The respondents were selected using non-probability sampling, specifically convenience sampling. Data was collected through an email survey, whereby a web-based self-administered questionnaire was distributed to the Applied Sciences, Commerce and Engineering students with assistance from the Information Technology Departments of the two polytechnics. The measuring instrument consisted of three sections with section A having nominal scales to gather demographic data from respondents. Section B consisted of scaled items that measured the influence of digital marketing activities, while section C measured brand awareness focussing on the three levels of brand awareness. A total of 500 completed questionnaires were received from the two polytechnics. Out of the 500 completed questionnaires, a total of 492 questionnaires had usable responses. Therefore, the current study had a response rate of 98.4%. The study further used descriptive statistics and inferential statistics to interpret the data. The descriptive statistics utilised included frequency measures of central tendency and measures of dispersion or variation. Regarding inferential statistics, the study utilised the CFA, Pearson‟s correlation coefficient, regression analysis, p-value independent sample t-test, ANOVAs and the Welch Robust test, Tukey HSD test, the Games-Howell test and the Cohen‟s d tests. The findings of the study revealed a significant relationship and a strong correlation between digital marketing activities and brand awareness. Regarding website use and brand awareness, a significant relationship and a moderate correlation were determined. The results further revealed an insignificant relationship but a moderate correlation between text messaging and brand awareness. The empirical results also revealed a significant relationship and a strong correlation between social media marketing and brand awareness. Finally, an insignificant relationship and a moderate correlation were revealed between email marketing and brand awareness in the current study. Based on the empirical results, this study gave recommendations to polytechnic marketers. Under the website use items, the study revealed that the respondents had a less positive experience with the web design of the polytechnics' websites. It was recommended that polytechnic marketers should take pragmatic steps to enhance their polytechnic web designs so that students can take note of the college information on well-organised polytechnic websites. The study also found that the respondents felt the need to experience more personalisation and timeliness of the polytechnics' text messaging. Therefore the polytechnic marketers were advised to personalise their text messages each time that they send them to students enabling them to build long-lasting relationships with students. Regarding the timeliness of text messaging, the polytechnic marketers were advised to send text messages to students at the right time when they need the information so that the disseminated information is readily accepted by the students. The polytechnic marketers were also advised to provide up-to-date polytechnic information on their social media pages after the respondents indicated the need to experience more sharing of content on the colleges' social media pages through the provision of up-to-date information. Lastly, the empirical results revealed that the respondents felt the need to experience more personalisation and the provision of interesting content through polytechnic email marketing. Therefore the Zimbabwean polytechnic marketers were strongly recommended to personalise the students' emails to motivate students to engage with them personally. The polytechnic marketers were further recommended to include interesting content in students' emails so that they draw the students' attention to polytechnic information in their emails. The study made the following important contributions. Firstly, the study made contributions to theory, literature, knowledge, society and marketing practitioners within the context of digital marketing activities and brand awareness in Zimbabwean polytechnics. Secondly, the current study provided the measuring instrument and a model that adds to scholarly work and provides a basis for future research in the marketing of Zimbabwean polytechnics. Thirdly, the study will assist in the enhancement of brand awareness of Zimbabwean polytechnics, enabling them to attract academically gifted students who will become productive workers, self-reliant entrepreneurs and responsible citizens. Lastly, the model will also provide a basis for future reference for polytechnic marketers in their marketing efforts for competitive advantage purposes. The current study had limitations that comprised uneven sample distribution, the adoption of limited social media variables and the exclusion of external stakeholders from the current study. Finally, the study made recommendations for future areas of study. , Thesis (PhD) -- Faculty of Business and Economic Sciences, School of Management Sciences, 2023

- Description: Sea turtles are ecologically important species that have endured a history of overexploitation. Combined with their long, complex life cycles and ongoing anthropogenic pressures, they remain conservation-dependent. Conservation efforts worldwide focus on sea turtle nesting beach protection, however, comprehensive management strategies require an understanding of their lives at sea which are often spent in distant waters. This understanding is hindered by the relative challenges of in-water studies. South Africa has also focused research and conservation efforts on nesting adult female loggerheads (Caretta caretta) and leatherbacks (Dermochelys coriacea), largely overlooking the species or age classes remaining at sea. Green turtles (Chelonia mydas), hawksbills (Eretmochelys imbricata) and non-breeding loggerheads are frequently stranded and rehabilitated by aquaria, and observed by recreational divers on reefs, suggesting year-round residency along the country’s entire seaboard. Recent technological advancements in photo-identification methods for sea turtles, underwater photography and internet connectivity allowing even recreational divers to become citizen scientists now place us on the verge of an exciting opportunity to unravel the cryptic in-water ecology of these species. The overall aim of this study was to conduct the first assessment of relative abundance, demographics, distribution, and behaviour of sea turtles on reefs within the iSimangaliso and Aliwal Shoal Marine Protected Areas (MPAs) on the east coast of South Africa. A robust photo-identification database was established from research dives, voluntourism and citizen science contributions over a two-year period. From 1057 sightings in the two MPAs, a total of 227 individual sea turtles were identified constituting three species (green turtles: n = 120; hawksbills: n = 46; loggerheads: n = 61). Their relative abundance was proportional to the overall sizes of the South West Indian Ocean (SWIO) populations (green turtles > hawksbills > loggerheads > leatherbacks). However, sightings per unit effort (SPUE) showed that loggerheads were more prevalent than hawksbills in iSimangaliso, likely due to its proximity to this loggerhead rookery. Reefs supported mixed size aggregations with juvenile to adult-sized green turtles (straight carapace lengths, SCLs of 44.9–99.2 cm), whilst hawksbills were mostly juveniles or subadults (SCL range: 37.4–73.4 cm) and loggerheads were mostly adult-sized (SCL range: 66.9–81 cm). Adult sex ratios were slightly female-biased but not significantly different from 1:1. The longest minimum residence periods recorded for individual subadult green and hawksbill turtles (676 and 675 days respectively) and adult-sized loggerheads (621 days) were suggestive of residency. Resident sea turtle activities were typical; they wereobserved foraging, resting, cleaning and interacting year-round, whilst only loggerheads and leatherbacks were observed in breeding behaviour (e.g., patrolling and mating) just after the seasonal arrival of transient individuals. This study thus reveals that the east coast of South Africa hosts regionally important resident and transient sea turtle aggregations with some of the highest SPUE results recorded for the region. This first attempt at monitoring foraging grounds using a variety of techniques and stakeholder groups can serve as the baseline assessment for future work and the foundation for a long-term in-water monitoring programme, allowing for expansion along the entire coastline. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2023

- Description: Direct anthropogenic impacts on vulnerable marine ecosystems are growing and require effective conservation measures. Integrating the cost impacts of conservation interventions and optimising the spatiotemporal scale of management interventions may improve cohesion between opposing marine users. This study aimed to integrate spatial and temporal models to advise dynamic penguin-fishery management plans in Algoa Bay, off Gqeberha, South Africa, that would maximise penguin foraging success while minimising the impact on the fishing industry. Determining the foraging locations important to breeding penguins is fundamental when understanding the relationship between fisheries and prey availability. Using Global Positioning System (GPS) data gathered from feeding trips of breeding African penguins between 2012 and 2017, and a hidden Markov model, three behavioural states (foraging, commuting, transitioning) were inferred and used as conservation targets in spatial prioritisation using the prioritizr package in R. The cost to the fishery was estimated using the catch of pelagic fish by the fishing industry between 2012 and 2015 as the proxy. The energetic cost to penguins was the distance they travelled from their breeding colony. Nine prioritisation scenarios, varying in levels of conservation for penguins, spatial cohesion and costs to fisheries, were developed using all year’s combined data to explore an ‘optimal’ closure configuration. The optimal closure was determined as an area which met the targets for penguin conservation, with a low cost to the fishery, close to the breeding colony and spatially clumped. The best solution from each scenario was isolated and the solution for the conservation target of 20% foraging habitat, 10% commuting habitat and 10% transitioning habitat and a boundary penalty of 0.01 (a dimensionless value that is used to reduce spatial fragmentation – increasing the value of the parameter signals that it is important to minimise the total exposed boundary of the prioritisation by favouring solutions where units are clumped together) was chosen as the optimal closure. This configuration was used as a static closure and applied to individual fishing seasons to estimate how the cost of a static closure design to the fishery would vary between seasons. Subsequently, a dynamic closure was designed using the same optimal configuration criteria every year, and the cost to the fishing industry was compared seasonally with the cost of a static closure. The cost to fisheries of dynamic closures was consistently lower than that of a static closure and the area required to meet the penguin feeding targets was drastically reduced. While dynamic closure scenarios show promise to minimise costs to the industry while meeting penguin conservation targets, these configurations were designed retrospectively with data collected after the end of the fishery seasons. For efficient management, the closures need to be designed by using data collected at an appropriate temporal scale. For that, the critical missing dimension to this study is the addition of real-time data on pelagic fish positions, areas of fishing intensity and sites of penguin foraging to create appropriate recommendations for up-to-date fishery exclusion zones. Therefore, the priority now is to explore methods of collecting real-time data on pelagic fish abundance, feeding behaviour of penguins at sea, site and mass of pelagic fishery catch, and using these data to delineate real-time, dynamic closures, coupled with a governance and management strategy that can implement dynamic closures. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2023

- Description: This dissertation examines the competitiveness of management consulting (MC) of small, medium, and micro enterprises (SMMEs) in serving state-owned enterprises (SOEs) in South Africa (SA). The research focused on the preparedness, scalability, and sustainability of MC SMMEs in addressing the strategic challenges faced by SOEs. The mixed-method approach combined self-administered interviews with management consultants and a comprehensive literature review. The qualitative research method allowed for an in-depth exploration of the factors influencing the competitiveness of MC SMMEs. The interviews revealed that MC SMMEs possess the necessary technical expertise and skills, yet they face hurdles related to scalability and sustainability inherent in SMMEs. These challenges include limited access to funding, inadequate marketing capacities, and delayed payment for services rendered. The study highlights that MC SMMEs can handle high-value projects for SOEs but they encounter difficulties within the SOE environment, which is marked by ethical concerns. It emphasises the importance of vigilance and maintaining discipline in service delivery to address these challenges. Additionally, the research provides practical recommendations for SOEs to support and facilitate the growth of MC SMMEs, enabling innovative solutions in their services. By evaluating the competitiveness of MC SMMEs in serving SOEs, this research contributes to understanding the MC industry landscape in SA. It aims to assist in strengthening the capabilities and credibility of local MC SMMEs, fostering their growth and sustainability. The findings offer valuable insights for policymakers, industry practitioners, and stakeholders seeking to enhance the role of MC SMMEs in driving economic growth and innovation within the context of SOEs. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2023

- Description: Colon cancer like any other cancer is a condition in which cells grow uncontrollably and may even spread to other regions of the body through metastasis. Colon cancer was ranked the second leading cause of cancer related deaths worldwide in 2018. Research to advance treatment of cancer keeps advancing daily, However, a big challenge is drug-induced side effects due to toxicity against normal body cells. Therefore, the development of controlled release technologies in conjunction with targeted drug delivery may provide a more efficient and less dangerous approach to overcome the limits of traditional chemotherapy. Including the creation of nanoscale delivery vehicles capable of directing the release of chemotherapeutic drugs into cancer cells only. This study aims to investigate p14 peptide that would specifically target colorectal cancer cells and not normal body cells to develop a targeted drug delivery system using gold nanoparticles. This study serves as a pilot study of the primary aim. To achieve this, the effect of the peptide p14 and peptide functionalized gold nanoparticles (p14-AuNP) on colon cancer cells (HT-29) and normal epithelial cells (KMST-6) was determined. Firstly, gold nanoparticles were chemically synthesised and then functionalized with p14 peptide through Polyethylene glycol. Then assessment of their effect through in vitro cytotoxicity assay (MTT) and gene expression analysis (RT-qPCR) was conducted. Nanoparticles’ synthesis and functionalization was performed and confirmed: In vitro cytotoxicity through MTT assay was successfully conducted and p14-AuNP showed toxicity against colon cancer cells and lesser toxicity towards normal cells as compared to 5-Flourouracil (commercially approved drug for colon cancer treatment). Gene expression analysis revealed that apoptosis was induced in both cell lines by p14-AuNP either through upregulation of caspase 3, 7 and/or BCL2. A cell survival gene, AKT1, also had significant effect on this. CDC42 was downregulated which indicates that cell proliferation was inhibited. , Thesis (MSc) -- Faculty of Science, School of Biomolecular & Chemical Sciences, 2023

- Description: The seasonal and interannual variability of the coastal Benguela upwelling system is described using 22 years (September 1993 - December 2014) of a regional Ocean model (ROMS) output. The model-derived SSTs are evaluated against satellite SSTs (GHRSST) and biases between the datasets investigated, allowing for confidence in using the ROMS data to investigate details of spatial and temporal variability over the Benguela System. Variability of coastal SSTs are investigated together with alongshore winds (from the ERA-Interim Reanalysis product). The driver of the seasonality in upwelling in the Benguela region is the seasonal shift of the South Atlantic High pressure system, leading to an enhanced seasonal signal in the southern Benguela (with strongest upwelling favourable winds in austral spring and summer). In the northern Benguela, the seasonal signal reduces with the peak of upwelling favourable winds shifting to late winter and spring. Interannual variability is evident in the model and is investigated with respect to various modes of climate variability. Though the direct relationship of the Benguela upwelling system to large-scale climate modes such as SAM and ENSO is not clear in most places, some evidence was found for their connection. For instance, in the southernmost cell of the southern Benguela a significant positive and negative correlation exists between SST and wind respectively with ENSO during summer months. This relates to increased (decreased) winds and decreased (increased) SST during La Niña (El Niño) events. Although there was no direct correlation with either SST or alongshore wind anywhere in the Benguela system, there was some indication of its importance. A trend toward a positive SAM (i.e a more poleward position of the South Atlantic High-Pressure system) was consistent with a trend toward enhanced winds and reduced SSTs in the southernmost upwelling cell. In addition to this, there was evidence to suggest that when SAM and ENSO are out-of-phase, which occurred primarily during summer months, the wind and SST response is amplified. This seemed to be particularly true in the first 10 years of the timeseries when the anomalies were strongly alternating. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2023

- Description: The study is an instrumental case study of Isadora Duncan (1877 - 1927). She was a pioneer of modern dance as she developed her unique style of dance that was free-flowing and natural. She further developed her own dance philosophy, which drew the attention of many as its archetypal dancer was a woman who embodied a space that was equal and free. She was not only revolutionary in her unique dance style but also for her strong beliefs. Isadora Duncan believed in anti-marriage, bearing children out of wedlock, and fighting for the emancipation of women where she used dance, her philosophy and post-performance lectures to communicate her thoughts and beliefs. An Instrumental case study is a qualitative method of enquiry, which entails researching an event or individual as a means of providing or gaining insight into a particular phenomenon. Similar to that of a psychobiography, the individual subject can be explored through the lens of a psychological theory for the purpose of creating a coherent psychological case study. The psychoanalytical lens of Carl Jung was used to explore and describe certain aspects of the life and work of Isadora Duncan. The subfield of the Psychology of Women provides a contextual description for the challenges that women faced in the past and in the present, and additionally presents the primary aim of the proposed study. Isadora Duncan was chosen due to her unique dance movement, both literally and figuratively as she developed her ability in giving voice to those emotions that women often kept hidden. She lived during significant times which included radical transformations that brought about noticeable change politically, socially, and culturally. Despite the reformative motions, it did not dismiss its own challenges especially for women. Women faced a constant struggle for freedom from oppression, community rights and gender equality, and Isadora Duncan was no exception to these challenges. Extensive biographical information data was collected and processed into salient features. The study integrates the theory of Carl Jung, the life and dance philosophy of Isadora Duncan and the v challenges faced by women over the centuries and demonstrates the value of using an instrumental case study as a method of inquiry into the exploration of a unique individual. The Psychology of Women provides an understanding of how those past challenges may still be modern-day concerns for the psychology of women today. The findings of the study demonstrated that Isadora Duncan was a unique and innovate women who pushed the boundaries socially. She was determined to perform her unique dance style in times that required women to conform to the cultural expectations. However, in times of trouble and despair, she was able to turn to dance as the individual and collective voice. The contribution of the study rests with its demonstration of the value of a holistic and reflexive exploration of a unique individual woman. It demonstrates the value and application of Jung’s in-depth theoretical understanding of the archetypes in human behaviour and the use of dance as a healing process for psychologically wounded women. Therefore, specific reference to the true inner voice of women allows insight into how clinicians might assist female clients who struggle to release their true inner voice. Furthermore, the study contributes to building knowledge of the challenges that women face in society and allows for future research of exploring integrative theoretical frameworks in understanding the healing of psychologically fragmented women in the 21st century. , Thesis (Ma) -- Faculty of Health Science, 2023

- Description: The growing concern about the negative impact of tourism on the social, cultural, and economic systems of local communities has caused policymakers to envision improved methods of tourism management. Governments realise that the feasibility of protected areas is dependent on giving considerable attention to the livelihoods of host communities and, according to them, a greater role in the management of protected areas. The worrying poverty rate of national park adjacent communities in Uganda has prompted an inquiry into the key drivers that could enhance sustainable livelihoods. As such, an inquiry into the intervention of tourism social enterprises in enhancing the livelihood of park adjacent communities has been sought. Presently, limited academic research has been conducted on the influence of vulnerability context, livelihood capital access and livelihood strategies on enhancing the sustainable livelihood outcomes of national park adjacent communities. Furthermore, the links between tourism social entrepreneurship and sustainable livelihoods have hardly been explored in literature. Against this background, the primary objective of this study is to investigate the influence of vulnerability context, livelihood capital access and livelihood strategies on the sustainable livelihood outcomes of national park adjacent communities where tourism social entrepreneurship is practised in Uganda. Considering the primary objective of the study and the researcher’s assumptions, a positivistic research paradigm with a deductive approach to theory development was adopted. A quantitative methodological approach was selected, and a survey research strategy and a cross-sectional approach were employed. The study used a questionnaire to gather primary data from potential respondents who were selected through simple random sampling. From the data collection, 364 usable questionnaires from Uganda Community Tourism Association (UCOTA) – exemplifying a tourism social enterprise were obtained. The primary data collected was analysed to investigate the hypothesised relationships between the independent and dependent variables. An Exploratory Factor Analysis (EFA) was performed to establish the factor structure of the variables and a confirmatory factor analysis (CFA) for each of the factors was assessed based on various goodness-of-fit indices. The suitability of the measuring instrument was determined by the validity and reliability tests from which the average variance extracted (AVE) estimates and squared correlations between the constructs and Cronbach’s alpha coefficients were reported; validity and reliability assessments of the factors were conducted to confirm the suitability of the measuring instrument. A modified hypothesised model was derived based on these analyses, after which the descriptive statistics and correlation results on the dependent and independent variables were then reported. The study used Structural Equation Modelling (SEM) statistical technique to test the significance of the hypothesised relationships. Significant relationships between resilience to shock and sustainable livelihood outcomes (improved well-being) and also resilience to seasonality and sustainable livelihood outcomes (improved well-being) for the case of vulnerability context. With regard to livelihood capital access, a significant relationship was found between social capital access and sustainable livelihood outcomes (improved well-being). A significant relationship between tourism-related strategies and sustainable livelihood outcomes (improved well-being was also found).This study has contributed to the body of knowledge of sustainable livelihoods in general as well as how vulnerability context, livelihood capital access and livelihood strategies influence sustainable livelihood outcomes of national park adjacent communities where tourism social entrepreneurship is practised. Theoretically, this study contributes to the application and extension of the sustainable livelihood framework by integrating a theory of access and the capability approach in assessing livelihoods. Practical recommendations were made that could enhance the sustainable livelihood of national park adjacent communities. , Thesis (PhD) -- Faculty of Business and Economic Sciences, School of Management Sciences, 2023

- Description: Background: Workers accidents at work have been demonstrated to be increasingly common and expensive, particularly in developing nations like South Africa. The failure of employers and employees to support and comply to (OHS) regulations measures frequently leads to injuries and accidents that are extremely expensive for both the employer and employees. Regardless of South African legislations that aim to prevent accidents and injuries, scourging statistics of industrial accidents are still a characteristic of OHS. Objectives: This study investigates knowledge gaps, attitude, and the practice of municipal workers regarding OHS at Garden Route District Municipality (GRDM) in the Western Cape Province of South Africa. Methodology: Quantitative approach was taken, and questionnaires were administered to 188 workers employed by the GRDM. A probability sampling method of stratified sampling method was utilised. Results: This study concluded that the workers of the GRDM are knowledgeable about OHS in their workplaces and that municipal workers positively perceive OHS issues in their workplaces. The main reason for this positive perception is because of the management support that the workers receive from the GRDM with regards to OHS matters. Furthermore most workers positively perceived OHS protocols and measures undertaken at the GRDM. Statistical tests proved that the municipal workers who positively perceived OHS protocols and measures were significantly higher (p< 0.05) than those that negatively perceived OHS protocols. Conclusion: The study revealed that GRDM workers were knowledgeable on OHS protocols. This was because of the support that they get from their employer as well as personal health and safety concerns. They positively perceived the OSH measures that are put in place to prevent accidents and injuries. It is only an insignificant percentage of individuals that disagreed with some of the OHS measures and protocols. This study contributes immeasurably to academic research in the field of OHS and extends knowledge that relates workers’ perceptions, safety awareness, as well as workers’ adherence to safety and behaviour. , Thesis (Ma) -- Faculty of Health Science, 2023

- Description: The emergence of social media (SM) in the academic arena has demonstrated the potential for innovation in teaching and learning. Moreover, its appeal is enhanced by its accessibility and affordability. Consequently, the use of SM has increased globally and has influenced interaction and socialisation amongst educators and learners. In addition, SM has affected learning and how educators teach and collaborate with learners when constructing knowledge in higher education settings. However, despite its advantages, nurse educators' use of SM is less than optimal in teaching. Therefore, the study aimed to explore nurse educators' knowledge, attitudes and practices regarding the use of SM as a teaching strategy at a public nursing college in the province of Limpopo, South Africa. The research design employed for this study was quantitative, explorative, descriptive and contextual, and Roger’s diffusion of innovation theory underpinned the study. Stratified, proportionate sampling was used to select the nurse educators who were respondents to the study’s survey via a questionnaire as the data collection instrument. An educator as a specialist in the use of SM, a statistician and the study supervisors reviewed the questionnaire. A pilot study was conducted to check the validity and reliability of the data collection instrument. Data gathered through the survey was statistically analysed to produce descriptive statistics. The researcher adhered to the ethical principles of respect, beneficence, and justice. The research results indicated that the nurse educators in the study were knowledgeable about SM platforms. Moreover, although they had a positive attitude towards incorporating SM as a teaching strategy. Therefore, based on the research results, recommendations were to facilitate the use of SM as a teaching strategy. , Thesis (Ma) -- Faculty of Health Science, 2023
