- Description: In a world where technology is evolving at an alarming rate there have been so many advancements and developments in the marketing field and how consumers engage in accessing products and services. In general, a great body of literature on information technology shows evidence that areas such as mobile banking and organisational technology adoption have been explored. However, limited attention has been dedicated to consumer adoption or acceptance stages of technology, particularly chatbots in the South African context. Apart from that, during the peak of the Covid 19 pandemic, consumers had to adjust to mainly doing transactions online as there was a restriction in accessing banking halls. Given this backdrop, the aim of this study is to address this particular research gap through investigating factors influencing consumers’ adoption of chatbot assisted marketing activities in the South African banking industry. The research was inspired and constructed upon three research theories, namely Technology Acceptance Model (TAM), The Diffusion of Innovation Theory (DoIT) and Unified Theory of Acceptance and Use of Technology 2 (UTAUT2). Based on these theories, a hypothesised model was formulated with eight independent variables, namely Perceived Usefulness, Perceived Ease of Use, Facilitating Conditions, Price Value, Hedonic Motivation, Social Influence, Perceived Compatibility and Relative Advantage. The dependent variable was put forward as Chatbot Adoption. Descriptive and explanatory research designs were selected for this study, utilising a quantitative research methodology. In addressing the objectives of the study, secondary data was collected through the internet, magazines, newspapers, articles, journals and books to aid in completing the literature chapters and construction of the measuring instrument. Primary data was also collected through a self-administered questionnaire which was created on QuestionPro and the link was distributed to the respondents. The population under study were consumers of the banking industry products and services in South Africa. The target respondents consisted of consumers who hold valid bank account and have used or experienced online activities within the banking sector. A non-probability vii sampling method through convenience and snowball sampling was adopted to recruit the respondents. Data were obtained from 151 usable survey questionnaires. The data collected from the respondents was coded and captured on a Microsoft excel spreadsheet which was then followed by analysing of data using IBM SPSS version 16. From the analysed results, all the suggested independent variables were retained as the respondents confirm in varying degrees the influence on behaviour that the factors have. The study found that the eight independent factors have practical and statistically significant correlation with consumer adoption of chatbot assisted marketing activities within the South African banking industry. In addition, the inferential ranking of the factors indicates that Relative Advantage, Perceived Usefulness and Price Value fall under one group of significant factors perceived by consumers in their decision to adopt chatbot assisted marketing activities. It can therefore be concluded that it is useful for the banking industry to implement the identified factors and recommendations offered to enhance the use of chatbots in consumers’ online banking activities as the responses obtained are in general favourable. The study thus contributes theoretically and practically to the body of knowledge particularly digital marketing through chatbots in the banking sector. Therefore, the findings can be useful for financial marketing, digital banking and the suggested model can help the marketing and artificial intelligence departments in the banking industry in the decision-making process. , Thesis (Ma) -- Faculty of Faculty of Business and Economic 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

- 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 use of technology alone cannot ensure a secure environment for organisations. Consideration should be given to the human aspect of cybersecurity. User errors are rooted in a lack of awareness and ignorance. A security awareness programme allows organisations to equip employees with the knowledge required to safeguard their data. The Security Education and Training (SEAT) course provided at the Nelson Mandela University seeks to bridge the gap by providing the necessary tools to equip students to be better employees for their future employers. However, the SEAT course is fairly outdated and has a poor user experience. Gamification has therefore been considered to address the user experience of the SEAT course. Incorporating game elements can help to increase the positive user experience of a system. User experience designers use gamification and well-chosen game elements to improve user experience. People enjoy using systems that are full of excitement, and that challenge and encourage a competitive spirit. The primary objective of this study is to provide recommendations for the gamification of the user experience of the SEAT course at the Nelson Mandela University. The primary objective is further divided into several secondary objectives that aim to address the proposed problem. The secondary objectives are to investigate user experience, identifying the most common user experience evaluation methods; to understand gamification and to identify relevant game elements that could enhance the user experience of the SEAT course at the Nelson Mandela University; to evaluate the user experience of the Nelson Mandela University SEAT course and to identify opportunities to implement the identified game elements; to implement the identified game elements into the selected module of the SEAT course. A literature review was conducted to gather an understanding of user experience, user experience evaluation methods, gamification, and game elements. A prototype was created using the information gathered in the literature review, based on a component of the SEAT course. The prototype incorporates different game elements that foster motivation in users. The prototype is used as a proof-of-concept, demonstrating that gamification can address the user experience of the SEAT course. Self-evaluations were conducted on both the SEAT course and the prototype, as a first step in comparing the user experience of the original SEAT course with the proof-of-concept prototype. Finally, gamification recommendations were proposed to address the user experience of the SEAT course. , Thesis (MIT) -- Faculty of Engineering, the Built Environment and Information Technology, School of Information Techonology, 2023

- Description: Health and safety (H&S) coordination between main contractors and subcontractors on construction projects is one of the most important factors for the success of a project. The aim of this study was to develop a framework to improve H&S coordination between main contractors and subcontractors on the Medupi power station project, and the objectives were to ascertain the H&S measures used to assess the H&S risks towards the reduction of hazards and injuries; assess the enforcement mechanisms of H&S regulations, and examine the challenges encountered in terms of the coordination of H&S at the Medupi power station project. Moreover, this research addressed the significant issue of possible ineffective coordination of H&S guidelines and policies in the South African construction industry, as well as at the Medupi power station project. This research will help to alleviate incidents and accidents at the Medupi power station project. The research entailed a review of the literature pertaining to H&S, and a questionnaire survey that was used to gain insight into the working conditions on site and to evaluate the state of H&S coordination, its implications, and compliance with the Construction Regulations by all parties concerned. A purposive sampling method was adopted to survey contractors working on the Medupi power station project. The research findings revealed that inadequate H&S communication between main contractors and subcontractors negatively affected project performance as it resulted in the occurrence of accidents on site. The research findings also revealed that most respondents, both main contractors and subcontractors, were aware, and clearly understood the required H&S practices. However, a small number indicated that they were uncertain with respect to such practices. This indicated that there was a gap in terms of H&S coordination between the main contractors and subcontractors on the Medupi power station project. The research findings further revealed that lack of commitment to H&S practices, inadequate communication / consultation relative to the implementation of the H&S management system (H&SMS), inadequate resources as well as inadequate contractor relations between the main contractors and subcontractors constituted barriers in terms of the H&SMS. 5 Recommendations included a need for the following relative to H&S: management leadership, worker participation, hazard identification and control, education and training, programme evaluation and improvement, and optimum communication and coordination for employers on multi-employer work sites. , Thesis (MSc) -- Faculty of Engineering, the Built Environment and Technology, 2023

- Description: In South Africa the construction industry has grown by more than 15% per annum over the past five-years and the construction industry is facing several pressures to decrease costs, improve productivity and to develop a competitive edge in terms of quality of service and customer satisfaction. Faced with a growing demand for service delivery the industry must seek new and improved ways to stay competitive in this market space. By effectively analysing the construction market all role players within the AEC industry can adopt new trends and techniques being implemented by either their foreign counterparts or direct competitors. One of these trends within the industry is technological innovations; each designed to play a beneficial role in construction industry advancements. It is clear that our industry is moving forward at an alarming rate, yet our foreign counterparts seem to be one step ahead. Based on the 2010 Soccer World Cup it was clear that the South African AEC Industry had the ability to conform and deliver on world class infrastructure, yet we still seem to have a slow adoption rate surrounding technological innovations. Investigating the depth of knowledge based around the most popular technological innovations currently being implemented can provide a clear view as to what S.A industry role players see as potentially profitable within our marketplace and the steps that could be taken to provide further research pertaining to those technological innovations which are being overlooked. Establishing the most prominent barriers preventing technological adoption within the South African AEC Industry can effectively be compared with those faced by foreign counterparts to mirror their solutions to similar problems. Finally, by establishing whether resistance to a changing environment plays a vital role in the hindrance to technological adoption one can access the extent to which the AEC Industry may effectively change based on a projected industry time frame. , Thesis (MSc) -- Faculty of Engineering, the Built Environment and Technology, School of the Built Environment, 2023

- Description: Worldwide, the topic of inner-city decay and regeneration continues to attract a lot of attention from various parties and organisations. This is largely due to the fact that Central Business Districts (CBDs) remain the heartbeat of any city’s economic, social and political vibrancy. It therefore remains an ongoing process for the government and private stakeholders to keep on devising strategies aimed at revitalising the inner-city. The problem of urban decay is however experienced more in the developing third world and is characterised by high unemployment rates, high crime rates, depopulation, desolate-looking landscapes, abandonment of buildings, split families amongst others. Urban decay does not have one single cause, but rather a combination of many, including poor urban planning, redlining, poverty, suburbanization, and racial discrimination. These factors have resulted in urban sprawl as property owners preferred to migrate from the increasingly toxic social and economic environment that now became of the inner-city. The study seeks to investigate the current state of urban decay in South African CBDs with a case study of Gqeberha metro city, it also investigates current efforts and measures in place for regeneration and lastly, recommendations that have been put and continue to be put in place for inner-city regeneration. The state of inner-city infrastructure, property development finance options, town planning requirements and regulations and the investment case are other factors that have been investigated. Various other aspects of inner-city dynamics in the context of property development have been explored with findings from extensive literature review and structured interviews enabling the researcher to come up with recommendations for sustainable inner-city regeneration. , Thesis (MSBE) --Faculty of Engineering Built Environment and Information Technology, School of Built Environment and Civil Engineering, 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

- 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: The principle of justification in radiographic imaging aims to best answer a medical question while evaluating the expected benefits of radiation exposure against the probable detriment to the individual patient. The implementation of justification in radiography requires the assessment and evaluation of chest mobile radiographic requests against justification criteria, considering the underpinning principles of radiation: justification, optimisation and authorisation. Diagnostic chest mobile radiographic imaging has been part of healthcare for the last century. Medico-legal requirements by the professional registration body, the Health Professions Council of South Africa (HPCSA), identify justification as an advocated and obligatory practice among radiographers. Yet, justification remains an inconsistent practice among South African radiographers due to several challenges in the healthcare setting. The aim of this study was to investigate the experiences of radiographers regarding the justification of chest mobile radiographic examination requests in a private radiology practice in the Nelson Mandela Bay Health District (NMBHD). A qualitative, exploratory-descriptive and contextual research design was used to gain in-depth data of the experiences of South African radiographers regarding the justification of chest mobile radiographic requests. Data were gathered from the participants using unstructured, open-ended, in-depth individual interviews. Data were transcribed verbatim and coded using Tesch’s eight steps of data coding and analysis process. Two principal themes were constructed during data analysis. Theme one identified the barriers and associated affective responses related to the appropriate implementation of justification of mobile chest radiographic examinations. Theme two recognised recommendations to enhance the implementation of justification by radiographers for mobile chest radiographic examinations. The research study was governed by methods to ensure trustworthiness and ethical practices. Based on the findings of this study, four recommendations were developed to assist radiographers to establish whether a request for mobile radiographic chest examinations is appropriately justified, which can contribute to establishing a radiation safety culture in the research setting pertaining to chest mobile radiography. , Thesis (MSc) -- Faculty of Health Science, School of Clinical Care Sciences, 2023

- Description: The main objective of the study was to evaluate building infrastructure delivery within the Department of Public Works and Infrastructure, Eastern Cape Province. The Department of Public Works and Infrastructure is a governmental section in charge for the development of infrastructure and delivery of government projects. The study adopted a quantitative research approach; the sampling technique that was used for the current study is the convenience sampling technique. This technique is also referred to as availability or accidental sampling. The population for the study consisted of respondents from the construction-consulting firms and contractors such as the Aurecon Group, Haw and Inglis Civil Engineering, the Metro Bay Municipality, and the National Home Builders Registration Council. The number of questionnaire that was distributed is about thirty-three (33) and about 36.4% response rate received. The findings of the study revealed the impact of the late payment on the progress of building infrastructure projects. The study indicated that, delayed payment to the contractor can affect the can affect the productivity adversely. It is also established that delayed payment includes unrealistic cash flows, error in clams, financial challenges and disagreements relating to the valuation of work. This implies that, payments that are processed on time to the contractors can be of critical importance on the success of the project, whilst on the other hand non-payment or delayed payment have a negative impact on the implementation of construction projects. In the context of building infrastructure projects delay is a regular and common problem, which has a negative impact on the overall project success particularly in the Eastern Cape Province. , Thesis (MSc) -- Faculty of Engineering, the Built Environment and Technology, School of Built Environment, 2023

- Description: The study aimed to affirm the appropriate leadership skills required of a project manager for a successful construction project. The study investigated the most prominent leadership skills among the City of Cape Town project managers, the most prominent project success factors, and the relationship between the prominent leadership skills and project success factors. Lastly, it determined the strategy to be used to enhance the leadership skills of the City of Cape Town construction project managers. The research was established upon the problem statement from which the sub-questions and hypotheses were derived. The research followed the explanatory sequential mixed method whereby primary data was first collected through a quantitative method and followed by a qualitative method. A pragmatism paradigm philosophy was used for its flexibility to combine both quantitative and qualitative research. The deductive and inductive approaches were used because they suited both qualitative and quantitative data. The research survey determined that communication is the most prominent leadership skill among the City of Cape Town project managers. Concerning the project success factor, quality was identified to be the most prominent project success factor among the City of Cape Town construction projects. The Pearson correlation analysis was subsequently undertaken to determine whether there is a relationship between leadership skills and project success factors. The results illustrated a strong and positive relationship between leadership skills and project success, indicating leadership skills lead to project success. The qualitative research portion of the study investigated what strategy can be implemented to enhance the leadership skills of City of Cape Town project managers. The findings confirmed that training and support-structure strategies are appropriate to improve a construction project manager’s leadership skills and that training does not guarantee good leadership performance; however, applying the training, monitoring, and mentoring leads to good leadership performance. The study also revealed that a support structure involves utilising consultants who are leadership experts. Recruiting professional officers for all departments within the City who would work in conjunction with project managers and senior managers is another form of a support structure to be used. Lastly, setting up one-on-one support sessions with project managers can also be useful. Every construction project manager needs to have leadership skills, and it is therefore recommended that the City choose a suitable strategy; however, combining the above strategies is also possible. , Thesis (MSc) -- Faculty of Engineering, School of the Built Environment and Technology, 2023
