- 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

- 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

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

- Description: This thesis forms part of the Nelson Mandela University biomass and nanotechnology project, which aims at using agricultural waste for many applications, including biomedical applications, water treatment, and agricultural films. Pineapple leaf fiber (PALF) is one of the natural fibers with the highest cellulose content (about 80%), and they produce about 2.5–3.3% of the weight of green leaves. However, the other parts of the pineapple fruit, such as the leaves and crown, are still treated as waste due to a lack of understanding of the benefits and risks of these parts of the pineapple fruit. The transformation of PALF as a renewable and abundantly available natural residue into cellulose fibers (CFs) will reduce the waste accumulated in the atmosphere, and it will add value to the cultivation of pineapple. In the biomedical industry, CF is very promising in terms of drug delivery. Cellulose acetate is a remarkable biomaterial extensively used in biomedical applications due to its properties such as being non-toxic, non-irritant, biodegradable, heat resistant, and less hygroscopic. In this research, the isolation, functionalization, and characterization of cellulose from PALFs were conducted. The PALFs were dried and ground into small particles before being alkali treated with sodium hydroxide to remove the non-cellulosic components. Moreover, the remaining lignin in the residue was removed using sodium chlorite and acetic acid; this process is known as the bleaching process. The bleaching process resulted in white CFs, which was an indication of the successful removal of the non-cellulosic material. The obtained CFs were further functionalized using acetic acid, acetic anhydride, and sulfuric acid, and this reaction is known as the acetylation reaction. Subsequently, both treated, untreated, and functionalized CFs were characterised using the following instruments: FTIR, SEM, SPM, TGA, XRD, and XPS. In the FTIR data of raw PALFs, the following functional groups were more pronounced: C-O, C=C-O, and C=O, whereas peak C-O-C disappeared and peak CH2, C-O, were less pronounced. These FTIR results confirmed the successful removal of non-cellulosic components. The SEM and SPM images visually suggested the partial removal of hemicellulose and lignin from the raw PALFs after the chemical treatment, which are the cementing materials around the fiber bundles. The TGA studies revealed good thermal stability for the isolated CFs from PALFs. The XRD diffractograms of the PALFs showed a cellulose I crystal pattern where the peaks were located at angular positions (2θ) of around 18°, 26°, and 41°. Lastly, after the functionalization of CFs, the cellulose structure remained intact (not damaged); instead, the newly ix introduced functional groups (the acetyl group) were attached at the ends of the cellulose structure. These results are therefore confirmation of the successful removal of non-cellulose material from the PALFs after the chemical treatment. , Thesis (MSc) -- Faculty of Science, School of Natural Resource Science and Management, 2023

- Description: Creep-resistant 1CrMoV steels are used for high-pressure turbine rotors in fossil fuel power stations operating at steam temperatures up to 565 °C in the creep regime. The upper bainitic microstructure of 1CrMoV rotors changes when exposed to high temperature service over long periods. The aim of this study was to relate these microstructural changes for service exposed 1CrMoV rotor steels to the remaining creep life as determined using existing methods. Analytical electron microscopy was used to quantitatively study the microstructural evolution of service-exposed 1CrMoV steel rotors. 1CrMoV rotor steel samples were characterised in the initial state, and three long-term (272 h to 300 kh) service exposed states. Detailed microstructural investigations were conducted to analyse the cavities; bainitic laths and packets; dislocations; carbide phases and their size, population, composition. The creep life fractions were estimated using conventional life assessment methods based on creep cavitation and hardness. The creep life fraction consumed of the rotors, estimated based on the creep cavities and hardness data, ranged from ~0.5 to 1. Electron backscattered diffraction (EBSD) was used to analyse the bainitic packets, laths, misorientations, and dislocations, which showed that the bainitic lath surface area to volume (SV) correlated with service time. The precipitates were extracted from the Fe-matrix using extraction replication and were further investigated using transmission Kikuchi diffraction (TKD), scanning transmission electron microscopy (STEM), selected area electron diffraction (SAED), and energy dispersive spectroscopy (EDS). STEM-EDS and TKD identified M3C, MC, M2C, M7C3, and M23C6 (M = Fe, Cr, Mo, V, Mn) in the 1CrMoV steels. STEM-EDS measurements revealed that Fe/Cr ratios in M3C decreased from 4.5 (initial state) to 2.5 (>272 kh). The Fe/Cr and Fe/Mo ratios in overall carbides decreased from 5 and 10 (initial state) to 1 and 2 (>272 kh), respectively. The TKD analysis indicated that the relative phase proportion of M2C and M7C3 carbides, relative to the total extracted carbides, is positively correlated with service exposure. These microstructural features correlate with the creep life fraction consumed and could potentially be used as another indicator of the remnant creep life. , Thesis (PhD) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics. 2023

- Description: In this study, we discussed a mathematical model that incorporates important interactions between normal cells, tumor cells, immune cells, and estrogen. The mathematical model was revised to include two control measures; namely surgery and hormone therapy to minimize the number of tumor cells. The model was mathematically analyzed with the premise that the two control measures are positive constants. Locally and globally analyses were performed using a variety of analytical methods to investigate the stability of the breast cancer model. Furthermore, an optimal control problem was formulated and used to determine the best strategy for reducing the number of tumor cells by incorporating hormone therapy and surgery, based on the well-known Pontryagin’s Maximum Principle. The numerical results indicates combining both optimal control measures (surgery and hormone therapy) simultaneously is more efficacious than using single control measure separately in decreasing the number of tumor cells. , Thesis (MSc) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2023

- Description: The high rates of unemployment and poverty in South Africa are significant barriers to economic advancement in the country. According to Statistics South Africa (2022), the country’s unemployment rate is 34.5 percent, while it has been reported that the proportion of the population living in poverty was 55.5 percent in 2020. Social entrepreneurship has been recognised as a means of tackling these socioeconomic challenges, by providing innovative social solutions. However, the lack of a universal definition for social entrepreneurship has caused misperceptions regarding its potential for job creation, poverty alleviation and economic development. In order to understand the relationship between social entrepreneurship and job creation, this study focused on existent perceptions of social entrepreneurship as pertaining to job creation in South Africa; the study used the Buffalo City Metropolitan Municipality as a case study. An in-depth literature review was conducted on the relevant literature related to the concept of social entrepreneurship, and its role in job creation. This study employed a qualitative research approach, in this respect, it relied on inductive reasoning. The research design followed the hermeneutic phenomenological method, for which non-probability purposive sampling was used in order to select participants. The study sample comprised of twelve social entrepreneurs registered on the Buffalo City Metropolitan Municipality's Local Economic Development database for social entrepreneurs. For the purpose of data collection, the study employed semi-structured interviews which relied on open-ended questions; in this regard, the study achieved a 100 percent response rate. The primary research findings indicated that the youth of the Buffalo City Metropolitan Municipality participate in, and promote, social entrepreneurship as a solution to the metropole’s high youth unemployment rate. The results of the study support current government policy by encouraging the implementation of local government policy initiatives that support social entrepreneurship, which could eventually result in the creation of jobs, and a decline in the country's unemployment rate. In addition, the study identified the need for government support, specifically in terms of the provision of funding and resources as a perceived government function; this would assist in the creation of social entrepreneurshipbased jobs. The study contributes to the existent body of work on the phenomenon of social entrepreneurship, and to further understanding the role this phenomenon plays in job creation in South Africa. Local government should acknowledge and support social entrepreneurship through the improvement of its current systems and the reallocation of government resources, so as to encourage openness and participation, in order to foster an environment that is vi favorable to social innovation. Furthermore, by capitalizing on the commercial aspects of social enterprises, and abandoning reliance on traditional Local Economic Development policies, local government can develop policy frameworks that promote socio-economic development in the Buffalo City Metropolitan Municipality , Thesis (MA) -- Faculty of business and economic sciences, 2023

- Description: Mental illness has become a global concern, with consequences that may result in a mental health pandemic. Studies conducted on mental illness suggest that religious and cultural beliefs not only affect the expression of mental illness, but also the diagnosis and treatment of mental conditions. South Africa is a country imbued with cultural and religious diversity, which creates different groupings of people, holding diverse beliefs regarding mental illness. In many contexts, supernatural beliefs, traditional healing and indigenous medicines and treatments are considered in the treatment of the symptoms associated with mental illnesses, especially on contexts where there is a reliance on religio-cultural beliefs. Even though there has been a significant increase in the contribution to research focusing on mental health in diverse contexts, much of this research has focused on subjective experiences. Little to no information is available on population-based studies in South Africa regarding mental illness in diverse contexts, thus limiting the generalisation of findings related to cultural and religious influences on mental illness. This dearth of information further limits the development of psychological interventions. The study aimed to explore how mental illness is perceived by the participants and thereafter explored the influence of culture and religion in coping with mental illness by the residents of the Eastern Cape. The study was quantitative in nature and adopted an exploratory-descriptive design. The researcher made use of a questionnaire as a research tool and QuestionPro was utilized as a platform. A convenience sampling technique was utilised. In ensuring rigour of the study, the researcher ensured maximal validity (accurate representation of the data) and reliability (ability to repeat the research procedure). Ethical principles have been adhered to as per the principles on the Belmont Report, to ensure safety of the participants and this includes anonymity, confidentiality and the right to withdraw from participation in the study. Data has been analysed using descriptive and inferential statistics. A sample size of 101 participants from the general population of residents of the Eastern Cape completed the online survey. The results of the study revealed that the residents of the Eastern Cape have substantial knowledge pertaining the cause of mental illness and indicated both positive and negative attitudes towards the mentally ill and possess coping strategies to deal with a mental illness. In addition, the results show that there is a relation between religion/culture and coping with a mental illness by the participants of the study. The findings of this study emphasize the necessity of public education efforts that understand and respect people's cultural diversity, as well as teamwork among traditional and medical professionals. Future studies should focus on the use of discourse analysis to better investigate indigenous groups' conceptions of mental illness and their views about its aetiology and treatment. , Thesis (MA) -- Faculty of Health Sciences, School of Behavioural Science, 2023

- Description: Personal Branding is deemed as an unavoidable aspect of entrepreneurship and social acceptance. Individuals should establish, develop, maintain and take advantage of a Personal Brand. The benefits of a Personal Brand should be embraced and used to market themselves and highlight their uniqueness. The aim is to investigate the relationship between Professional Life, Social Media Presence, Values, Competencies, Communication as the independent variables and Personal Branding as the dependent variable. It was concluded that there are important factors that positively influence Interpersonal Personal Brand as well as Intellectual Personal Brand, which are the two components that make up Personal Brand. There is limited research on the factors that influence Personal Branding in South Africa. Through literature review, factors were identified and used to form a conceptual model. This model was tested to measure their relationship with Personal Branding. An online questionnaire was distributed to MBA students, family and friends who made up the study’s respondents. The results obtained after conducting correlation and ChiSquare tests were used to determine the relationship between the identified factors with Personal Branding. This study explores how individuals can use Personal Branding as a marketing tool. These individuals include those who want to create or further expand their current Personal Brand and use it as a marketing tool. This treatise explored the factors needed to be considered for Personal Branding a marketing tool for individuals. Personal Branding can be used at the beginning of a career, during a transition of a career or even when wanting to explore a new career. Personal Brand was initially considered the only factor. However, this study concludes that Personal Branding is made of up of two components: Interpersonal Personal Branding as well as Intellectual Personal Branding. The findings concluded that independent factors, Professional Life, Values, Competencies and Communication all have a positive significant influence on Personal Branding as a whole, as well as the components it is made up of, Interpersonal Personal Branding and Intellectual Personal Branding. The independent factor Social Media Presence positively influences Interpersonal Personal Branding only. v This study makes theoretical contributions by broadening the definition of Personal Branding. The study defines the research methodologies for Personal Branding which could be used for future studies. The Associative Network Theory in relevance to Personal Branding is explored. The practical contribution of this research includes a hypothesised model which was tested. This study should be repeated to include a bigger sample size that is more equally distributed within South Africa. Additionally, for future studies, it would be recommended to incorporate the development of Personal Branding as an independent factor to measure its effect on Personal Branding. Another recommendation for further research is to conduct research on policies, which can be put forward to assist with the managing of Personal Branding for entrepreneurs. , Thesis (MSc) -- Faculty of Business and Economic Sciences, 2023

- Description: This study endeavoured to investigate the perspectives of principals and practitioners working in selected early childhood development (ECD) centres in the Buffalo Municipal District in the Eastern Cape, on the use of play-based techniques in educational and pedagogical practices of 3 to 4 years age group. Although most practitioners are aware of the significance of play-based learning, many report experiencing challenges when attempting to incorporate play-based strategies into their teaching of, and lessons aimed at, young children ages 3 to 4 years. For the purpose of ECD, it is recommended that the teaching of, and learning by, young children take the form of play (NCF, DBE, 2015). In this particular research undertaking, a qualitative design approach was adopted. A descriptive case study approach with semi-structured interviews as the key method of data generation was used to study play-based approaches between practitioners and children ages birth to four years at three ECD centres located within the Buffalo City Municipality District. Face-to-face interviews were conducted with the three principals of the ECD centres and six practitioners, during the data-collection phase. Recording of the interviews was done then they were transcribed and thematic coding employed before the data were analysed for themes. The study participants’ responses revealed that the insufficient professional training of practitioners, on play-based approaches, presented a challenge. Play as a way of teaching and developing young children is further hampered by a variety of issues such as poor infrastructure, unqualified practitioners, funding of the ECD centres and lack of relevant resources prevalent in the ECD sector. As the findings indicate, government intervention will facilitate the training of practitioners for in-depth knowledge and understanding of play methodology in ECD, while the sector will benefit from additional funding and infrastructure provision as this has impact on indoor and outdoor play-based activities, as well as the appointment of qualified human resources instead of job seekers. , Thesis (MEd) -- Faculty of Education, 2023

- Description: Palaeoichnology, the study of fossil tracks and traces, has had a relatively late start on the Cape south coast of South Africa. Since its inception in 2007 the Cape south coast ichnology project has led to the identification of 326 Pleistocene vertebrate ichnosites in aeolianites (cemented dunes) and cemented foreshore deposits between the community of Arniston in the west and the Robberg Peninsula in the east, a distance of approximately 350 kilometres. As a result, significant palaeoevironmental, palaeocological and palaeoanthropological inferences have been made. This thesis brings together this corpus of work, and attempts to answer the question of how ichnology can inform the understanding of the Cape south coast Pleistocene environment, and how the trace fossil record can complement the body fossil record. Achieving this objective involves the development of a definitive regional account. This includes descriptions of the regional geological context, Quaternary sea-level changes, and the state of knowledge of the region’s Pleistocene palaeoenvironment, palaeoanthropology, and body fossil record, along with an understanding of the roles of substrate and taphonomy in regional ichnology. A discussion of geochronology includes the age results from specimens submitted for dating through optically stimulated luminescence – dated deposits range in age from Marine Isotope Stage 11 through Marine Isotope Srage 3. The body of the thesis is formed by systematic descriptions of the vertebrate ichnosites, accompanied by interpretation and comments. Three databases have been compiled: ichnosites, photographs, and photogrammetry images. In synthesizing this data, four underlying questions are addressed: what is the global relevance of the Cape south coast ichnosites, how can these studies complement the vertebrate body fossil record, how can they contribute to the understanding of Pleistocene palaeoenvironments and palaeocology, and how can they contribute to palaeoanthropology? The Cape south coast is of global ichnological importance. Unanticipated findings which augment the sparse reptilian body fossil record include tracks and traces of crocodiles, monitor lizards, very large tortoises (the first of their kind in the global record), and hatchling sea turtles. Two new ichnogenera have been erected to describe the sea turtle tracks, each containing a new ichnospecies: ustralochelichnus agulhasii and Marinerichnus latus. Avian ichnosites are the oldest in southern v Africa, and include the presence of tracks of larger-than-expected birds, which may represent large chronosubspecies or may suggest the possibility of extinctions which are not evident from the body fossil record. Unique examples of the non-hominin mammalian ichnosites include sand-swimming traces that resemble those of the ‘Namib mole’: as a result a new ichnogenus (Natatorichnus) has been erected, containing two ichnospecies, N. subarenosa and N. sulcatus. The first elephant trunk-drag impressions and the first pinniped ichnosites in the global record have been identified. The role of elephant tracks as precursors to coastal potholes was previously unsuspected. Equid tracksites indicate a widespread presence of the extinct giant Cape horse (Equus capensis). The identification of a giraffe tracksite represents a major range extension. In particular, tracks and traces of giraffe, crocodiles, breeding sea turtles, and sand-swimming golden moles have significant palaeoenvironmental implications. , Thesis (PhD) -- Faculty of Science, School of Environmental Sciences, 2023

- Description: Forest nurseries are exposed to many challenges during the production of plant material, with pests and pathogens two of the most important. Management of pests and diseases require the use of multiple methods, including cultural, biological, and chemical control strategies in an integrated nursery pest management plan (IPM). In most nurseries, where hygiene practices and biological controls do not prevent the presence of pests and pathogens, they are managed through the use of pesticides. Forestry companies are regulated by both Government and Forestry Certification bodies. These include South African legislation pertaining to pesticides regulated by the Registrar Act 36 of 1947, the Forest Stewardship Council (FSC) and the Programme for the Endorsement of Forest Certification (PEFC). A limited number of pesticides, with an even more limited range of active ingredients, and not targeting all known plantation forestry pests/pathogens, are currently registered for use against pests and pathogens in plantation forestry in South Africa. Many of these have been in use for more than a decade, posing a serious risk in terms of resistance build-up. There is a major need for the identification and testing of additional/alternative products (biological natural or synthetic) for use against the range of pests and pathogens that occur on the various plantation tree species and hybrid combinations that are raised in nurseries. , Thesis (MSc) -- Faculty of Science, School of Natural Resource Science & Management, 2023

- Description: Throughout the recent history of South Africa, the increasing requirements from state and private sector healthcare institutions have relied heavily upon medical imaging technologies for the purposes of improved patient healthcare and service quality standards. Developments in this field of healthcare have seen many interesting and challenging operational changes: from the first implementation and use of X-ray equipment demonstrated in Krugersdorp in 1899; to the current advanced digital systems found in the medical imaging services sector of healthcare. This research study measured the medical imaging operational staff perceptions about new advanced medical imaging equipment and technologies. The theory crossed the academic disciplines through a quantitative survey about technology, operations management and healthcare. Together with staff perceptions about future medical imaging technologies’ usefulness and ease of use, the findings may impact their daily operations within a conducive technology acceptance management paradigm. , Thesis (MA) -- Faculty of Faculty of Business and Economic Sciences, 2023
