- Description: Coastal zones the world over are particularly attractive for the development of human settlements. Naturally, this trend frequently results in human induced disturbances of sensitive ecosystems, often resulting in dramatic and unintended consequences. The South African coastline is no stranger to this phenomenon. Dynamics at the population-environment-development interface in the coastal zone often presents affected communities and institutions with complex challenges. An infamous case along the South African coastline is the settlement of St Francis Bay, the focus of this dissertation. St Francis Bay was established as a holiday village around sixty years ago and its economy is today firmly dependent on the fragile bond and reciprocal relationship between the tourist trade and the integrity of sandy beaches. The dissertation, against this background and drawing from complex systems theory, explores the links between human activity and the biophysical environment and the ominous costs and consequences that are produced at the local population-environment-development interface. Domains that are considered within the nexus of relevant aspects include the wind-driven sediment bypass system across the local headland; climate change; the local economy; social wellbeing, inequality and social justice; as well urban planning and political governance. The desktop study applied to St Francis Bay made use of Geographic Information Systems and statistical information to form the basis of the methodological approach in this dissertation. The Population-Environment-Development nexus was formed as a result. The results illustrate how critical levels of beach erosion are connected amidst an intricate reciprocal nexus to these and other aspects. It demonstrates that the sustainability of the settlement hinges on the understanding of such linkages and underscores the relevance of the methodological approach that is applied. The sustainability of the environment and the resulting impact on the quality of life of the human population remains a challenge for future generations as well as governance systems. By acknowledging and understanding the complexity that exists in coastal zones allows for future research on the topic to be explored and enable key role players to proactively intervene to benefit the population and the environment. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2023

- Description: Modern shoppers are inundated with purchasing options in every product category, with thousands of brands competing for their patronage. It has therefore become increasingly important for organisations to differentiate product offerings in the market if they want to be competitive. It has further been highlighted that an individual’s experience of a brand is of paramount importance, as it is directly linked to brand loyalty. A vehicle for creating memorable brand experiences is the utilisation of multi-sensory experiences or sensory branding. Within the context of traditional or in-store shopping, sensory branding encompasses the use of visual, auditory, olfactory, tactile and gustatory stimuli to adjust consumer purchasing behaviour. However, more and more consumers are opting for online shopping, spurred on by the effects of the global COVID-19 pandemic, and are no less demanding of brands online than they would be in-store. The cosmetics and personal care industry is one of the more predominant gainers from e-commerce. The skincare industry exhibited one of the largest growth rates from 2019 – 2025 and had an estimated market value of $155.8 billion in 2022. When considering the South African skincare industry in isolation, there is no exception, categorised by high average growth rates and many competitive players in the market. This is apparent when considering that the skincare industry within South Africa is expcted to grow annually by 5.48% from 2023 to 2027, translating to an industry value of $788.4 million by 2027 (Statista 2023). With reference to in-store shopping for skincare products, sensory marketing strategies have been known to be heavily relied on. Therefore, with consumers moving towards online shopping, it is essential for skincare businesses to consider how to deliver sensory experiences online as well as in-store. Whilst the importance of the use of sensory branding and marketing in the skincare industry is notable, both in-store and online, it was established that while there is research available on sensory branding, there is very limited academic research on digital sensory branding and the sensory branding of v skincare products. Moreover, to the researcher’s knowledge, no academic literature specifically investigates the digital sensory branding of skincare brands. Therefore, this study will contribute not only by adding academic research to the topic being investigated but also through rreccomendations made based on the outcomes of this study to skincare brands in South Africa. From the comprehensive literature review, a conceptual model was constructed to investigate the relationship between traditional and digital sensory branding strategies (independent variables) and brand loyalty (dependent variable). Two sets of hypotheses were formulated relating to the identified variables of this study and the empirical research conducted was utilised to deduce whether these hypotheses should be rejected or supported. To conduct the empirical research needed for this study, certain research methodology was employed. This study made use of a positivistic paradigm and a quantitative approach. The target population of this study constituted consumers who had purchased skincare products in-store as well as online and, as no true sample frame existed, respondents were selected through the use of non-probability sampling, more specifically, convenience sampling. To collect the data, an online survey was used, with the specific data collection instrument being a web-based self-administered questionnaire, which was distributed via social media platforms, such as Facebook and LinkedIn, as well as via email. Section A of the questionnaire focused on the demographic details of the respondents, while Section B – Section F related to the variables of the study. A total of 372 potential respondents started the questionnaire, however only 321 questionnaires were deemed usable after the data had been coded and cleaned, indicating a response rate of 86.3%. This study made use of both descriptive (measures of central tendency as well as standard deviation and skewness) and inferential (SEM Models, Primary Models, Pearson’s correlation coefficients, Chi-Square test of Association, ANOVAs and Welch Robust test, Tukey test and Games Howell Test as well as Cohen’s d) statistics to interpret the data, which was graphically illustrated. vi The empirical investigation conducted in this study between the variables and sub-variables revealed that significant relationships exist between traditional sensory branding strategies (traditional olfactory and tactile stimuli) and digital sensory branding strategies (digital visual, olfactory and tactile stimuli) and brand loyalty, with refence to the skincare industry. It was further notable that, with specific reference to the skincare industry, the sense of sight, smell and touch are key factors for sensory branding, whereas auditory stimuli were found to only be useful when used in unison with the other senses. Moreover, with reference to in-store shopping, it was deduced that consumers shop for skincare mostly via retail outlets, which could lead to sensory overload. Furthermore, the results of this study suggest that younger consumers are price sensitive. Based on the pertinent empirical results, and corresponding literature findings, of this study, recommendations were provided to businesses operating in the skincare industry. With reference to in-store trading, it was recommended that because skincare is mostly sold via retail outlets, the brand itself does not have control over all sensory stimuli to which the consumer is exposed. As a result, consumers may be subject to sensory overload and skincare brands should keep their sensory branding in-store simple. Moreover, skincare brands could make use of an in-store aesthetician or beautician, which would facilitate consumer-product interaction. With regards to online trading, a recommendation for skincare brands would be to use moving images or GIFs, which will allow the consumer to more easily imagine the feel of the product. Moreover, skincare brands can make use of brand ambassadors to create “unboxing” videos, which will convey more clearly the sensory information of the product and instil confidence in consumers. Reccomendations were also made with reference to the financial state of consumers, as the financial position of the respondents could influence their decision making. The limitations of this study comprised the availability of reliable existing sources to support the study as the concept of digital sensory branding is still relatively new and, due to the study being focused on the skincare industry, taste stimuli were excluded as they were found to have no relevance. Finally, vii based on all the literature findings and empirical results, recommendations for future areas of study were made. This study provides evidence that both traditional and digital sensory branding strategies have an influence on, or relationship with, brand loyalty. Through this study, the importance of sensory branding, with specific reference to the skincare industry, is brought to light. Furthermore, skincare brands can utilise the information provided to improve the experience of their consumers when shopping in-store, as well as online, thereby increasing their base of brand loyal consumers. , Thesis (PhD) -- Faculty of Business and Economic Sciences, 2023

- Description: Determinants of performance in KZN Nonprofit organisations operating in the health sector is explored by this research paper. The focus is on the role played by sustainability orientation and dynamic capabilities on the organisational perfomance. Sustainability orientation and dynamic capabilities have received little empirical attention within the NPO sector. Most, of the research done has focused on for-profit organisations. Local NPOs in the health sector are facing many challenges. These are fueled by the high demand for services and scarcity of resources to deliver on their social mission. This study aims to examine the stated constructs. Furthermore, the study aims to help NPOs build sustainable organisations and adopt strategies that will increase the efficiency and effectiveness in their operations. The study employed a quantitative methodology. An online survey and experiental analysis were conducted on a sample of 156 respondents. All of the participants belong to local NPOs in the health sector in KZN. The hypotheses were tested by applying multiple linear regression. The Cronbach’s alpha coefficient was used to assess the reliability of the established variables and constructs. The results of the analysis show a significant and positive relationship between sustainability orientation and organisational performance. The study also found that the ability to sense, seize, and reconfigure mediate the relationship and positively influence the performance. These results provide important insight for local NPOs, policy makers, and current practices concerned about developing sustainable organisations. This implies that there is a chance for local NPOs to grow, attract funders and remain sustainable. In addition the results could help to build a reputable brand in their respective fields. , Thesis (MA) -- Faculty of Faculty of Business and Economic Sciences, 2023

- Description: The Addo Elephant National Park (AENP) is an ecologically sensitive environment where the increase in elephant population, especially in a changing climate is a recipe for landscape degradation and biodiversity loss. The Park is situated in the drought prone Eastern Cape Province, however, the effects of drought on thicket vegetation is less understood. This study aimed to distinguish elephant-induced thicket degradation from the effects of climatic factors, using remote sensing, GIS, and statistical techniques. To characterise and map vegetation conditions of the reserve temporal series Landsat imagery (n = 22) from 1998 to 2018 were analysed. Vegetation states were determined using Normalised Difference Vegetation Index (NDVI) derived from the growing season of the study period. Using supervised per-pixel image classification technique, the NDVI values characterized into distinct land cover classes viz (1) Intact Thicket, (2) Transformed Thicket, (3) Degraded Thicket, (4) Bare Ground and (6) Water Bodies. Post-classification change detection and landscape fragmentation analysis was performed. Climatic data were obtained from existing weather stations and raster surface of accumulated rainfall and mean maximum temperature were developed using the Inverse Distance Weighting (IDW). Time series analysis was implemented on the NDVI and climatic condition data by plotting annual measures to indicate variable trends. Temporal trend analysis was performed on the NDVI data using the nonparametric Mann-Kendall trend analysis test to indicate thicket vegetation condition improvement and general degradation. The Residual Trend (RESTREND) approach was employed to remove the effect of rainfall on vegetation productivity. This involved using the Ordinary Least Square regression functionality in ArcMap to compute the relationship between ∑NDVI and accumulated rainfall for every pixel for the study period. The products of the regression were assessed using Pearson’s Correlation (r) at a significance level of 90% (p-value ≤ 0.1) to distinguish strong relationships. Overlay analysis was performed, using the NDVI trend slope and the correlation coefficient (r) raster surfaces, to model vegetation dynamics influenced by elephant activities. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2023

- Description: Rangelands offer great opportunities for mutualisms between nature conservation and economic productivity if positive feedback loops can be identified and described. The effects of different livestock management practices are controversial. This research examined the effect of different grazing intensities on soil health using springtails (Collembola) and ants (Formicidae) as bioindicators, combined with soil and vegetation variables. The relationship between rangeland managers and rangeland ecosystems, particularly with regard to feedback loops between land care and economic production, was also investigated. Bioindicator samples were collected at different treatments of livestock grazing intensity and a questionnaire was submitted to 65 rangeland managers in the semi-arid Nama-Karoo biome of South Africa. In most cases we found no significant relationship between grazing intensity and Collembola and ant community composition, vegetation variables, and soil variables. The few significant relationships we found were contradictory in their implications for the effect of high intensity grazing on soil health. The results suggested that differences in livestock management are relatively unimportant for soil health, at least in semi-arid systems under conditions immediately following a drought. The questionnaire yielded results on outline of management practices, basis of management decisions, consequences of monitoring veld to inform management decisions, and indicators of successful management. Respondents characterized by higher ecological fluency focused on livestock production when making management decisions, stocked at higher densities, and monitored the rangeland ecosystem to inform their decisions. For monitoring the ecosystem, they used bioindicators such as diversity of biota, successional stage, and ecologically important functional groups. We concluded that the development of ecological knowledge in rangeland managers enables the establishment of feedback loops between ecosystem services and services to ecosystems, which are desirable for economic productivity and nature conservation. Development of relevant ecological knowledge and management techniques should be based on forums and dialogue among rangeland managers, developing distributed cognition and resilience in the community of rangeland managers. , Thesis (MSc) -- Faculty of Science, School Natural Resource Science and Management, 2023

- Description: The majority of the land reform beneficiaries have remained poor, with some being worse off than before. Despite the various government initiatives to address issues of food insecurity and poverty alleviation, there has been slow progress in terms of producing enough food to ensure local and national food security. In South Africa, the Recapitalisation and Development Programme (RECAP) was initiated to alleviate the challenges faced by land redistribution and restitution recipient farmers such as inadequate post-settlement support to increase farms production output in order for them to become successful commercial farms. Several farmers have benefitted from this programme and the have been able to increase production output while others are still struggling, or worse showing zero output. These mixed outcomes call into question the efficacy of RECAP and the need to understand why some farmers are successful while others are not. This study adopted a qualitative comparative case study approach of six RECAP beneficiary citrus farms located in the Amathole District of the Eastern Cape as well as their respective strategic partner and mentors. The findings of the study were analysed with the employ of reflexive thematic analysis. The study found that RECAP recipient citrus producers in Amathole have experienced varying degrees of success with access to finance being the key obstacle to success. Significantly, the study found that the challenges around finance do not relate primarily to the purchase of inputs to production, as was the previous understanding, but rather relate to the securing of title deeds and having a history of receiving finance which combined allow farmers to access additional finance when needed. The findings of this study have practical implications for policymakers as land reform and food security remain key Development challenges in South Africa that have been exacerbated by climate change. , Thesis (Ma) -- Faculty of Faculty of Business and Economic Sciences, 2023

In South Africa, the Recapitalisation and Development Programme (RECAP) was initiated to alleviate the challenges faced by land redistribution and restitution recipient farmers such as inadequate post-settlement support to increase farms production output in order for them to become successful commercial farms. Several farmers have benefitted from this programme and the have been able to increase production output while others are still struggling, or worse showing zero output. These mixed outcomes call into question the efficacy of RECAP and the need to understand why some farmers are successful while others are not. This study adopted a qualitative comparative case study approach of six RECAP beneficiary citrus farms located in the Amathole District of the Eastern Cape as well as their respective strategic partner and mentors. The findings of the study were analysed with the employ of reflexive thematic analysis. The study found that RECAP recipient citrus producers in Amathole have experienced varying degrees of success with access to finance being the key obstacle to success. Significantly, the study found that the challenges around finance do not relate primarily to the purchase of inputs to production, as was the previous understanding, but rather relate to the securing of title deeds and having a history of receiving finance which combined allow farmers to access additional finance when needed. The findings of this study have practical implications for policymakers as land reform and food security remain key Development challenges in South Africa that have been exacerbated by climate change. , Thesis (Ma) -- Faculty of Faculty of Business and Economic Sciences, 2023

- Description: Estuaries are notable for their biodiversity, productive and invertible fisheries, and significant capacities. This study assesses the economic value of the Swartkops and Sundays estuaries in Algoa Bay, Gqeberha, to estuary users and local communities1 . The data was collected from December 2021 to April 2022, during the summer and autumn seasons. The seasons are considered peak times; however, international travel was restricted during Covid-19 level one lockdown. The study employs both the Travel Cost method and the Choice experiment method. Based on the findings, anglers and bait collectors in Swartkops Estuary sell their catches for an average of R77.41. The majority of these anglers and bait collectors earn between R0 and R1 583 per month and rely on catch and bait for a living, with the majority of participants benefiting from provisioning ecosystem service. Sundays estuary users, on the other hand, primarily use the estuary for recreational purposes. Anglers visiting Swartkops and Sundays estuaries spend R4 709 128 and R2 203 158 annually on food and beverages, fuel/transport costs, bait. This contributes R7 534 572.67 and R3 525 052.18 to the local economy in Nelson Mandela Bay Municipality based on the multiplier. The study emphasizes the importance of estuary management and monitoring to preserve and protect them for future generations. The primary issue is to extract resources from the Swartkops and Sundays estuaries in a sustainable manner while also protecting them. Estuaries can help grow the economy if managed well and used in a sustainable way. , Thesis (MA) -- Faculty of Business and Economic Science, 2023

- Description: The effects of pests and the need to produce adequate food have influenced small-scale farmers in disadvantaged communities to adopt and utilise natural plant pesticides to improve harvests in many Southern African Development Communities. However, the phytochemistry associated with these indigenous plants’ pesticide activity still needs to be explored. The lack of evidence of scientific knowledge of the plant species has caused a lot of health issues among the users of indigenous plant pesticides. Solanum incanum is among the plants utilised to control cabbage aphids in Mkoba village, Zimbabwe. Solanum species are known for their steroidal compounds which comprise glycoalkaloids and saponins. This study evaluated the knowledge, opinions, and attitudes of the vegetable peasant farming community in Gweru regarding their use of the indigenous plant (S. incanum) as a pesticide. The study also reported the phytochemical profiling, structural characterisation of the isolated compounds, and biological and pesticidal activity evaluation of phytochemicals isolated from S. incanum. A descriptive survey was carried out to assess the knowledge, attitude, and practices of a conveniently sampled group of vegetable farmers in Mkoba village who use S. incanum as a pesticide. Forty-nine respondents comprised of 19 males and 30 females of ages ranging from 15 to above 60 years took part in the study by answering an open and closed-ended questionnaire. The survey revealed that parents and neighbours were instrumental in disseminating pesticidal information in the community. Brassica napus were the most grown.vegetable and vulnerable to cabbage aphids. Mixed opinions amongst the respondents varied regarding the health and environmental impact of S. incanum as a pesticide. Seventy-five percent (75%) of the respondents supported the use of S. incanum as a pesticide whilst 25% claimed that the use of S. incanum was the source of the health problems experienced in the community. The survey demonstrated that (45)91% of the farmers displayed poor practices regarding the disposal of empty pesticide containers and the use of personal protective clothing. The most prevalent symptoms in the community were skin rash, nausea, headache, and poor vision and these symptoms were common in the age group 30 to 60 years. , Thesis (PhD) -- Faculty of Science, School of biomolecular and Chemical Sciences, 2023

- Description: South Africa continues to experience unacceptably high Human Immunodeficiency Virus HIV incidence rates among youths aged 15 to 24 years. Remarkably, this is despite the numerous youth HIV prevention programmes that have been implemented in the country. Unfortunately, the programmes have not significantly curbed the spread of HIV due to the partial and fragmented nature of their implementation. The programmes are also observed to be weak in addressing complex economic factors recognised as important structural drivers for vulnerabilities that put youths at risk of HIV infection. To address this challenge, there is increased adoption and implementation of the Combination Social Protection introduced in this research as the CSP by Non-Governmental Organisations NGOs. The CSP is a youth empowerment programming strategy whose critical foundations are entrenched in combining economic strengthening interventions and HIV prevention education. CSP could provide youths with a set of indispensable life skills that enhance their competencies and agency to make informed and effective decisions regarding their health and economic lives. Despite its growing traction, little is known regarding links between the CSP and its abilities to improve HIV prevention outcomes for youths. Given the paucity of research, this study aimed to explore the experiences of youths participating in the CSP and HIV prevention programme, with a particular focus on the resource-constrained settings of Gauteng Province in South Africa. This study employed a collective case study design, within the qualitative approach, and was exploratory. In-depth individual interviews were conducted with 30 youths from six established NGOs in the City of Johannesburg (CoJ). Qualitative thematic analysis was employed as a data analysis strategy. Focus groups were separately with six practitioners from the same six NGOs, and five officials from the Department of Social Development (DSD). Both phases of data collection were guided by interview themes, which were aligned with the objectives of the study. The findings of the study point to the fact that the CSP’s innovative and holistic approach offered numerous transformative and empowering benefits to youths. It equipped them with basic informational resources, capabilities, and social assets to safeguard their health and aid their economic advancement. The programme’s mixedgender sessions provided space, freedom, and support for youths to engage on issues of gender, differential access to health and socio-economic opportunities. Another major finding of the study was that improvement of economic aptitude (brought about by financial literacy education), employability, and entrepreneurship training stirred a sense of agency and purposefulness among youths, which in turn, prompted them to be more focused on achieving long-term objectives instead of indulging in risky sexual practices. Conversely, findings revealed that the programme had limited opportunities and did not create an adequate supportive environment for youths to develop successful entrepreneurial or income-generating projects. There was also no structure to assist youths to access apprenticeship and employment markets. The study specifically recognised that the programme’s efforts to develop youths’ entrepreneurship and employability capabilities were curtailed by a lack of mentorshipnand access to financial capital for start-up costs. With these findings in mind, recommendations are made for the creation of an enabling environment by purposefully engaging youths, establishing collaborative relations with communities, and building networks with businesses and financial institutions that can help youths with capital, mentorship, and linkages to internship and wage employment. Such collaborations could be fundamental in unravelling the impact of the programme on building livelihoods and reducing HIV among youths. Hence, this study proposes a model with strategies to support the successful implementation of economic strengthening interventions for youths. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2023

- Description: Morphologies have evolved due to trade-offs between competing selective pressures. This is especially true for the skull. Not only does it contain the brain and the organs that are responsible for sensory function, but it is also contains components that play important roles in feeding, breathing, balance, defence, aggression and communication. The pinnipeds, a group of species that has evolved from terrestrial origins and became adapted to the marine environment, are under numerous selective pressures within the marine environment. These species have had to evolve in order to capture and process food underwater, and to dive. In addition, they are also characterised by substantial sexual size dimorphism in some species. Pinnipeds also make use of numerous marine and haul-out habitats with varying characteristics and complexity. Hybridisation has been recorded among pinnipeds, resulting in the production of hybrid offspring with characteristics that are different to their parent species. The aim of the study was to investigate the effect of these life history characteristics on skull and mandible morphology of pinniped species using three dimensional geometric morphometrics. To achieve this, 43 skull and 15 mandible 3D landmarks were collected using a Microscribe G2X digitizer with 0.2mm accuracy, on the skull and mandibles of 17 species of pinnipeds across three families, and one hybrid species. In total, 96 specimens across these species were examined. Data on the different life history characteristics of each species were collected from the literature. These data were plotted onto the PCA results in order to create and visually compare minimum convex polygons for each life history category. The results found that phylogeny, feeding strategy and sexual dimorphism were the most important factors in explaining differences in pinniped skull and mandible shape and size. may have resulted in these changes. Similarly, the inclusion of more species, covering a broader range of life histories may be beneficial. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2023

- Description: The increase in the number of channels driven by technology trajectory over the years have led to a change in customer behaviour. Customers move around different retailer platforms during a single purchase; even so customers still expect a superior and seamless customer experience while navigating these channels. The present study built on studies conducted in countries such as China, Spain, India, United Kingdom amongst others to determine if the learnings from these countries can be applied in the South African context. This study used an interpretivist phenomenological approach and interviewed a qualitative sample of participants to gain insights on their experiences while shopping in these retailers. This study will assist Information Technology managers with prioritisation of their technology roadmaps. This study will also contribute to computer science studies because programmers will have a context of a customer’s perspective when developing omnichannel solutions. Lastly, the study can be used by governments and policy makers in developing national strategic plans relating to shared economy because the study highlights the need to omnichannel retailing in remote areas. The findings from the research were summarised into five themes customer experience, convenience, product, support, and security. The optimal South African omnichannel retail experience is one that allows the customer to seamlessly move across channels by integrating the retailing mix elements of product, place, promotion, price. To achieve this experience, retailers must integrate the customer’s profile information and ensure that the customer’s payment details are secure and are able to seamlessly login in all the retailer platforms. Contrary to the researcher’s expectations, South African customers do not expect an omnichannel support. They expect to keep online support separate from in-store support. , Thesis (MA) -- Faculty of Business and Economic Sciences, 2023

- Description: The South African automotive industry is a key driver of the economy and industrialisation of the country. The Covid-19 pandemic has had adverse effects on many industries globally. In the automotive industry, Covid-19 affected the supply chain resulting in a shortage of semi-conductors, which are essential in the microchips used in the vehicle assembly process. The delays in supply resulted in decreased production volumes and thus a decline in sales which has had an adverse effect on the economic growth of the industry. Therefore, the automotive industry must be sustainable and agile to be competitive globally. This study aimed to focus on total quality management (TQM) practices as a tool for competitive advantage. TQM is significant for sustainability, business continuity and competitive advantage. The study highlights the relevance of TQM practices in the global automotive industry and in South Africa where the study was performed. The organisations at the base of the study are multinational original equipment manufacturers (OEMs) that manufacture passenger vehicles for both local and export markets. This quantitative study investigated the relationship between leadership support, quality culture, education and training, structure and resources, and strategic quality plan as the independent variables and TQM practices as the dependent variable. A closed-ended online survey with 70 respondents was employed to collect the data from the OEMs. The findings are that there is a positive and significant correlation between the variables. Leadership support, quality culture and strategic quality planning have more influence on the success of TQM practices. Education and training, and structure and resources have a moderate influence on TQM practices. Managers in quality assurance and production in automotive organisations need to prioritise leadership support, quality culture and strategic quality planning for TQM practices to succeed. , Thesis (MA) -- Faculty of Faculty of Business and Economic Sciences, 2023

- Description: The financial sector plays a pivotal role in an economy of a country; hence the importance of financial sector development cannot be underestimated. Financial sector development is widely regarded as another conduit through which financial innovation and economic growth can be alleviated. The study firstly empirically examines the effect of financial sector development on financial innovation and also the impact of financial sector development and financial innovation on economic growth in selected Southern African Development Community (SADC) countries, employing the Generalized Method of Moments (GMM) technique for the period 1990 to 2020. Empirical results revealed that financial sector development overall does have an impact on financial innovation in the selected SADC countries. And also, financial sector development together with financial innovation does have an impact on economic growth in the selected SADC countries. However, on the relationship between financial system stability, financial innovation and economic growth, results reveal that a stable financial system is beneficial to new technological advancement and improved economic growth. Therefore, the overall findings from the study indicate that financial access or financial inclusion and financial stability is what increases financial innovation and boosts economic growth instead of mere financial sector development at a broader level. , Thesis (MCom) -- Faculty of Management and Commerce, 2023

Empirical results revealed that financial sector development overall does have an impact on financial innovation in the selected SADC countries. And also, financial sector development together with financial innovation does have an impact on economic growth in the selected SADC countries. However, on the relationship between financial system stability, financial innovation and economic growth, results reveal that a stable financial system is beneficial to new technological advancement and improved economic growth. Therefore, the overall findings from the study indicate that financial access or financial inclusion and financial stability is what increases financial innovation and boosts economic growth instead of mere financial sector development at a broader level. , Thesis (MCom) -- Faculty of Management and Commerce, 2023

- Description: The study examined the relationship between fiscal consolidation and economic growth in South Africa (SA) in comparison with the Organisation for Economic Cooperation and Development (OECD) countries. The study emphasizes the use of fiscal consolidation as a tool to stimulate economic growth and reduce the budget deficit, focusing on the reforms of public revenues and expenditures. Moreover, the study employed the panel Autoregressive Distributed Lag (PARDL) model to explore the relationship between fiscal consolidation and economic growth in SA and three OECD countries from the period 1990 - 2018. The cointegration analysis confirmed the existence of cointegration between the variables which suggested that there is a long-run relationship among the variables. As a result, both long and short run dynamic models were evaluated. The result of the study shows that fiscal consolidation positively affects economic growth in South Africa in the long run, whilst in OECD countries fiscal consolidation negatively affects economic growth, both in the short and long run. Low government debt in South Africa due to lower deficit translated to a higher economic growth whilst higher debt level in OECD countries due to higher government spending translated to higher economic growth, one of the main differences in the relationship between fiscal consolidation and economic growth in South Africa and OECD countries is their spending pattern. Majority of South Africa’s budget is spent on inefficient state-owned enterprises, which have accounted for the bulk of government contingent liabilities, resulting in high borrowing costs, which consequently lead to high borrowing cost, thus the rising central government debt as a percentage of GDP. Unlike in SA, OECD countries spend towards capital expenditure specifically in priority areas such as infrastructure, Technology, and transport hence their high debt levels result in higher economic growth. In attempt to stimulate South Africa's economic growth, it is recommended that South Africa implement effective fiscal consolidations based on expenditure adjustments rather than revenue adjustments, as expenditure adjustments are more likely to reduce deficits and debt-to-GDP ratios and are more effective. In addition, the South African fiscal stimulus package can be used to invest more in infrastructure to increase private capital accumulation and stimulate economic growth. However, South Africa must exercise caution when reducing expenditures to avoid a reduction in development spending, which could lead to a decline in unemployment. , Thesis (Ma) -- Faculty of Faculty of Business and Economic Sciences, 2023

- Description: The purpose of this study is to determine whether foreign aid influences the quality of life in South Africa. To do so, the study analyses the relationship between foreign aid and the human development index (HDI). HDI consists of three other indices: the index of wellbeing, the index of education, and the index of income. To measure the relationship between foreign aid and HDI, five Autoregressive Distributed Lag (ARDL) models are used in estimating the effect of foreign aid on HDI as well as life expectancy, education level, unemployment, and GDP per capita from 1993 to 2019. Income, population density, and credit are given to the private sector are part of the empirical models as controlled variables. The results show that no significant relationship exists between foreign aid and HDI, education, and GDP, while aid is linked to a lower life expectancy rate and unemployment. These findings imply that aid can increase the HDI in South Africa by contributing to a decreased unemployment rate, and thus policy makers should establish concrete plans and develop economic strategies that focus on creating incentives that attract more aid, especially in the short run. This can lead to a decrease in the unemployment rate, which is often regarded as South Africa’s biggest economic issue. , Thesis (Ma) -- Faculty of Faculty of Business and Economic Sciences, 2023

- Description: The essence of this thesis was to study the effectiveness of integrating digital media technologies within the pedagogical approaches adopted and implemented in private and public high schools in a comparative manner. The study looked closely at private and public high schools of the Eastern Cape Province, to study the gaps of accessibility to technology by schools. The study identified the Eastern Cape Province as having a problem of poor performance in matric results at the end of each year as compared to other South African provinces. In order to select the relevant sample for the study, the researcher has utilized two secondary schools private and public in Makhanda Grahamstown and one public secondary school in Alice. The pragmatic paradigm was used to inform the study and used the mixed methods approach to data collection. The researcher distributed closed ended questionnaires to the learners in the three selected secondary schools and semi-structured interviews for the principals of the schools. The key findings reveal that the digital media tools are used for the teaching and learning purposes as well as communication to the schools’ stakeholders. The findings also revealed that various online platforms are utilized for teaching and sharing of information. For example, D6 and Ibambisa School Communicator app, WhatsApp groups for learners, Facebook, Instagram and School website for potential stakeholders. Hence, the results of this study should contribute to the field of ICTs and education in the country to solve the problems facing the teaching and learning systems of private and public schools of the Eastern Cape. Most schools (especially the public) do not have access to digital media tools in their classrooms. Thus, they still depend heavily on the textbooks, which may be outdated or not enough for all learners. In response to the issues faced by the Eastern Cape secondary schools and the findings, the researcher has suggested a model named the Digital Media and Pedagogy Integration DMPI Model of Communication. This model will contribute to the body of knowledge by providing advice to the Department of Basic Education on how teachers and learners can utilize digital media tools effectively. Also, the study has recommended that there is a need for provision of computer literacy training for teachers in secondary schools in this digital age. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2023

- Description: Saving electricity is a trending topic due to the electricity challenges that are being faced globally. Smart environments are environments that are equipped with physical objects, which include computers, sensors, actuators, smartphones, and wearable devices interconnected together through the Internet of Things. The Internet of Things provides a network to achieve communication, and computation abilities to provide individuals with smart services anytime, and anywhere. Rapid developments in information technology have increased the number of smart appliances being used, leading to increased electricity usage. Devices and appliances in Smart Environments continue to consume electricity even when not in use, because of the standby function. The problems arise as the electricity consumption of the standby function accumulates to large amounts. Effective communication through visualisation of the electricity consumption in a Smart Environment provides a viable solution to reducing the consumption of electricity. This research aimed to design and developed a visualisation system that successfully communicates electricity consumption to the user using a variety of visualisation techniques. The Design Science Research Methodology was used to address the research questions and was used to iteratively design and develop an energy usage visualisation system. The visualisation system was created for the Smart Lab at the Nelson Mandela University's Department of Computing Sciences. A usability study was conducted to assess the usability and efficacy of the system. The system was found to be usable and effective in communicating power usage to potential customers, since the participants were able to complete the tasks in a short amount of time. The positive results show that visualisation can aid in communicating electricity usage to customers, resulting in a possible reduction in electricity consumption and improved decision-making. , Thesis (MSc) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2023

- Description: All around the world there are small, medium and micro-enterprises (SMMEs) that help by creating jobs and contributing to gross domestic product. However, funding is a major problem that limits the growth and development of SMMEs. Funding challenges have increased, hence the need for research to be conducted in Komani, in South Africa‟s Eastern Cape Province, to see how the challenge can be overcome. This research aims at investigating the funding challenges experienced by SMMEs in Komani. The objectives of the research were to: evaluate the effect of funding challenges on the number of people employed in SMMEs; establish reasons why SMMEs fail to obtain funding from major financial institutions; to examine the avenues available for funding SMMEs; and to recommend to policymakers and SMMEs how to solve the problem of funding. However, previous research in Komani has not managed to investigate this problem with regard to the research process and the method used. This research is based on the positivistic paradigm and used the quantitative method to investigate the funding challenges. The research population was 441 SMMEs; of them 82 SMMEs were sampled using questionnaires. Data collected was analysed using Excel and Stata. Pearson Chi-square test of association from Stata and Excel Analysis ToolPak were used. The study found that most SMMEs use retained earnings and informal funding to finance their operations. It also found that most SMMEs were unaware of government support agencies like SEFA. The research recommends that more must be done to raise awareness on a regular basis to make sure that all SMMEs are aware of the financial support system that the government has for the SMMEs. Financial institutions will need to lower their requirements when SMMEs apply for finance. Finally, SMMEs are supported financially by both the government and the private sector to employ more people. However, the government could also create a guarantee scheme for SMMEs to ensure successful credit applications , Thesis (MA) -- Faculty of business and economic sciences, 2023

- Description: The study aimed to determine whether plant species could be classified by using high resolution aerial imagery and a convolutional neural network (CNN). The full capabilities of a CNN were examined including testing whether the platform could be used for land cover and the evaluation of land change over time. A drone or unmanned aerial vehicle (UAV) was used to collect the aerial data of the study area, and 45 subplots were used for the image analysis. The CNN was coded and operated in RStudio, and digitised data from the input imagery were used as training and validation data by the programme to learn features. Four classifications were performed using various quantities of input data to access the performance of the neural network. In addition, tests were performed to understand whether the CNN could be used as a land cover and land change detection tool. Accuracy assessments were done on the results to test reliability and accuracy. The best-performing classification achieved an average user and producer accuracy of above 90%, while the overall accuracy was 93%, and the kappa coefficient score was 0.86. The CNN was also able to predict the land coverage area of Opuntia to be within 4% of the ground truthing data area. A change in land cover over time was detected by the programme after the manual clearing of the invasive plant had been undertaken. This research has determined that the use of a CNN in remote sensing is a very powerful tool for supervised image classifications and that it can be used for monitoring land cover by accurately estimating the spatial distribution of plant species and by monitoring the species' growth or decline over time. A CNN could also be used as a tool for landowners to prove that they are making efforts to clear invasive species from their land. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2023

- Description: As the Anthropocene continues to be characterised by ever rising temperature highs, increasingly sporadic and extreme climatic events, and their accompanying mass mortality events, climate scientists now warn that the continued climate destabilisation may for the first time in recorded history prevent terrestrial homeothermic endotherms from being able to thermoregulate. Having evolved to maintain body temperatures (Tbs) well above their ambient (Ta) conditions, these endotherms have evolved a suite of adaptations to a colder environment to allow for homeothermic thermoregulation to occur. However, by the same vein, having evolved in a colder climate to stay warm also has led to a reduced capacity to prevent heat stress when temperature conditions are elevated. In absence of behavioural counter measures, the only physiological means available to thermoregulation to prevent such heat stress is that of evaporative water loss (EWL). If still inefficient, the endotherm will risk becoming hyperthermic. Literature has established that excessive heat exposure or reduced evaporative cooling capacities strain or retard thermoregulatory processes. If an endotherm experiences severe heat exposure, the rate at which passive heating is experienced will increase. Should an endotherm be in a humid environment, evaporative cooling efficiency is reduced. As a result, these two abiotic factors are therefore known to contribute towards heat storage, and therefore thermal stress. However, should both factors occur in the same environment, the heat stress effects are compounded, creating an environment dangerous for thermoregulating endotherms. For this reason, authors have emphasised that future wet-bulb (Tw) conditions may pose a penultimate threat to thermoregulating endotherms. Being a measure of coldest temperature attainable as a result of evaporative cooling, Tw has been proposed to represent a lower temperature thermal limit to endothermic thermoregulation. Once reaching a 2°C differential below an endotherms Tb (Tb – Tw = 2˚C), Tw is believed to impede the evaporative cooling process and, consequentially, commit endotherms to becoming hyperthermic. Considering that most mammals defend constant Tbs within the range of predicted Tw maxima increases that future Tw conditions may pose a significant threat to mammalian thermoregulation. However, to date, despite being well supported in the literature, ii empirical investigations into how extreme Tw conditions will affect endothermic thermoregulation are scant. Therefore, understanding of the proposed inhibitory nature of extreme Tw conditions is lacking. Considering that such conditions are to have a profound effect of endothermic survival, this dearth in understanding could prove fatal. As such, this thesis sought to provide evidence on how extreme Tw conditions may affect thermoregulatory processes in homeothermic endotherms. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2023
