- Description: Deficits in sustained attention are ubiquitous across numerous neuropsychological disorders. Besides being critical in learning, memory, and general cognitive capacity, sustained attention is thought to be the primary foundation for ‘higher’ cognitive functions including, divided, selective, and focused attention. Despite the above, sustained attention remains the lesser-researched form of attention. Sustained attention is thought to be regulated by the default mode network and the central executive network, the latter of which is situated in the dorsolateral prefrontal cortex (DLPFC), a brain region typically associated with sustained attention. Given the contributions of sustained attention in overall cognitive functioning, alternative and natural methods used to enhance this type of executive function are important. One alternative method is yoga exercise, where yoga is thought to place the body into the most favourable state to enhance sustained attention capacity. This study found a significant (p = 0.018) difference between the yoga and control group in incongruent response accuracy scores in the SCWT. However, no statistically significant differences (p < 0.05) were observed in fNIRS individual and group analyses, SCWT congruent and incongruent reaction time, as well as congruent response accuracy. This suggests that short-term yoga practice may improve behavioural markers for sustained attention, at least in terms of cognitive interference. , Thesis (MA) -- Faculty of Humanities, Psychology, 2024

- Description: The rise of multidrug resistance (MDR) has become a pressing global issue, hindering the treatment of cancers and infectious diseases, and imposing a burden on healthcare systems and the economy. The Multidrug and Toxic compound Extrusion (MATE) superfamily of membrane efflux transporters is one of the key players contributing to MDR due to their ability to export a wide range of cationic and hydrophilic xenobiotics, including treatment drugs, from cells, diminishing their efficacy. Targeting MATE transporters holds great promise in achieving some cellular control over MDR, but first, a deeper understanding of their structure-function-dynamics link is required. This study aimed to explore the MATE transporters as potential antimicrobial drug targets using a two-fold in silico approach. First, virtual screening of compounds from the South African Natural Compounds Database (SANCDB) was performed to identify prospective lead inhibitory compounds against the MATE transporters using molecular docking, and top hits were selected based on their binding energy and interaction with the active site on the N-lobe of the protein. Second, to investigate the molecular-level dynamics of their extrusion mechanism, the MATE transporter structures were embedded in a POPC membrane bilayer using the CHARMM-GUI online tool and then subjected to MD simulations for 100 ns with the CHARMM 36m force field using GROMACS. The resulting trajectories were evaluated using three standard metrics – RMSD, RMSF, and Rg; significant global structural changes were observed and key functional regions in both membrane- and non-membrane transmembrane (TM) segments were identified, containing more dynamic and flexible residues than other regions. Furthermore, the MATE transporters showed more of a loosely-packed structure, providing flexibility to allow for conformational switching during their substrate-transport cycle, which is typical for proteins whose secondary structures are composed of all α-helices. The scope of this study lied in the preliminary stages of the computer-aided drug design process, and provided insights that can be used to guide the development of strategies aimed at regulating or inhibiting the function of the MATE transporters, offering a possible future solution to the growing challenge of MDR. , Thesis (MSc) -- Faculty of Science, Biochemistry and Microbiology, 2024

- Description: Machine learning has experienced significant growth in recent decades, driven by advancements in computational power and data storage. One of the applications of machine learning is in the field of number theory. Prime numbers hold significant importance in mathematics and its applications, for example in cryptography, owing to their distinct properties. Therefore, it is crucial to efficiently obtain the complete list of primes below a given threshold, with low relatively computational cost. This study extensively explores a deterministic scheme, proposed by Hawing and Okouma (2016), that is centered around Consecutive Composite Odd Numbers, showing the link between these numbers and prime numbers by examining their internal structure. The main objective of this dissertation is to develop two main artificial intelligence agents capable of learning and recognizing patterns within a list of consecutive composite odd numbers. To achieve this, the mathematical foundations of the deterministic scheme are used to generate a dataset of consecutive composite odd numbers. This dataset is further transformed into a dataset of differences to simplify the prediction problem. A literature review is conducted which encompasses research from the domains of machine learning and deep learning. Two main machine learning algorithms are implemented along with their variations, Long Short-Term Memory Networks and Error Correction Neural Networks. These models are trained independently on two separate but related datasets, the dataset of consecutive composite odd numbers and the dataset of differences between those numbers. The evaluation of these models includes relevant metrics, for example, Root Mean Square Error, Mean Absolute Percentage Error, Theil U coefficient, and Directional Accuracy. Through a comparative analysis, the study identifies the top-performing 3 models, with a particular emphasis on accuracy and computational efficiency. The results indicate that the LSTM model, when trained on difference data and coupled with exponential smoothing, displays superior performance as the most accurate model overall. It achieves a RMSE of 0.08, which significantly outperforms the dataset’s standard deviation of 0.42. This model exceeds the performance of basic estimator models, implying that a data-driven approach utilizing machine learning techniques can provide valuable insights in the field of number theory. The second best model, the ECNN trained on difference data combined with exponential smoothing, achieves an RMSE of 0.28. However, it is worth mentioning that this model is the most computationally efficient, being 32 times faster than the LSTM model. , Thesis (MSc) -- Faculty of Science, Mathematics, 2024

- Description: The COVID-19 pandemic resulted in unprecedented challenges across various aspects of life. In particular, pregnant women encountered unique challenges and circumstances that necessitated adaptation to the experience of the perinatal period1 Satyanarayana et al., (2011). A considerable amount of research has been conducted regarding women's experience of the perinatal period during COVID-19, especially in first world countries. However, inadequate research has been done in the South African context and specifically, there is a lack of qualitative research providing thick descriptions of experience. The analysis describes three master themes supported by subordinate themes. The main themes are (1) A sense of loss and change, (2) Managing COVID-19 and its regulations during the perinatal period, and (3) Glimmers of hope and desirable aftermaths. The study’s findings expand and support the growing literature of women’s experiences on the perinatal period during the COVID-19 pandemic. , Thesis (MA) -- Faculty of Humanities, Psychology, 2024

- Description: The South African current account balance has been deteriorating over the years. An investigation of the correlation between capital mobility and economic growth is of interest as South Africa is heavily reliant on capital inflows to finance the current account deficit. This research topic is of importance as there is need to devise policies that maximise the benefits the nation derives from capital mobility. The benefits that capital flows provide economies, theoretically outweigh the disadvantages, provided that capital flows are absorbed productively. The topic is also of interest in the light of the magnitude of shocks to the South African economy such as the rand crisis, dotcom bubble, stock market bubble, inflation targeting, commodity super cycle, global financial crisis, the Covid-19 pandemic and Russo-Ukrainian War, as these shocks have translated to slower economic growth and higher levels of inflation. These shocks have equally revealed that countries need to have sound macroeconomic policies in order to survive the impact of any crises. The vision 2030 secretariat has identified capital markets as the key providers of capital required for achieving social economic blueprint. The empirical evidence locally is limited in comparison to the empirical evidence from outside of South Africa. This topic is of importance as South African studies on this topic are not as recent and this study aims to bridge that gap. Data were obtained from the South African Reserve Bank Quarterly Bulletin and the World Bank database for the period 1990 to 2022. The Autoregressive Distribution Lag model was employed in order to determine the relationship. This study relied on the supply-leading theory which posits capital markets may positively or negatively affect key indicators of economic growth. The study found that there is a positive long run relationship between net capital flows, saving-investment ratio and economic growth and a negative long run relationship between the degree of trade openness and economic growth. The findings will allow opportunity to address capital flow surges and in turn boost investor confidence. Capital flow management measures can help manage destabilizing exchange rate movements and capital flows coupled with macroprudential tools helping reduce the domestic buildup of vulnerabilities. , Thesis (MCom) -- Faculty of Commerce, Economics and Economic History, 2024

- Description: South Africa’s household debt relative to GDP has risen rapidly over the past decade. There is concern that high levels of household debt may decrease spending in the future and hence in the long run slow down economic growth. Thus, this study investigates the impact of household debt on growth in South Africa from 1987Q3 to 2022Q1. The research draws upon first-generation theories which include the absolute income hypothesis, life cycle hypothesis, and permanent income hypothesis, and second-generation theories which include the neo-Kaleckian model, the Super multiplier model, and the Steindl model. The impact of this relationship is assessed using a Vector Autoregressive (VAR) model, with a Toda-Yamamoto modification for some regressions. It is discovered that household debt has a positive short-term influence on economic growth, however, the influence is weak, and it decreases in the long run. Types of household debt such as credit card debt have shown to have a positive and strong influence on economic growth in South Africa from the short run to the long run, however, mortgage debt has shown weak positive influence on economic growth from the short 105 run to the long run. The study found that the growth maximizing ratios for household debt to 106 GDP ratio is 70 percent. The growth maximising credit card debt level is ZAR 72 403, in nominal terms and for mortgage debt is ZAR 5 980 000. The findings are expected to assist policymakers such as central banks and government authorities in formulating relevant policies to ensure economic sustainability through macro-prudential policy and strategies for household debt management. , Thesis (MEcon) -- Faculty of Commerce, Economics and Economic History, 2024

- Description: Shared perceptions by stakeholders can improve the understanding of managing natural resources. This study aimed to evaluate stakeholders’ perceptions towards co-management of small-scale fisheries to improve the management of these resources. Eleven participants were purposively sampled from government agencies, non-profit organisations and community representatives from Coffee Bay, Port St Johns, Lusikisiki and Xolobeni on the Wild Coast of South Africa. Predetermined themes derived from the literature were used to develop the interview schedule. Semi-structured, one-on-one interviews were conducted to probe the participants’ understanding of the term “co-management” and its objectives, benefits, processes, and outcomes. Data were recorded and transcribed into text, and thematic analysis was used to detect themes that emerged from the data. The results indicated that all participants perceived co-management of Small-scale fisheries as beneficial. Securing access rights through fishing permits was a benefit that was exclusive to the fishers, whereas self-regulation, sharing of information, and mobilising and utilising the strengths of different stakeholders were the benefits noted by all stakeholder participants. Government representatives viewed the involvement of government in the co-management structures of SSF as necessary, whereas the other representatives’ views were that government should be excluded. Incorporating the traditional and government regulatory systems was recommended to manage fisheries resources effectively. The benefits of co-management exceeded costs, suggesting that co-management was viable for the Wild Coast. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2024

- Description: Climate change and resource scarcity have become some of the world's most critical problems and are among the most significant megatrends influencing world leaders' agendas in decision- making (Rothkopf & Casey, 2014; International Social Security Association, 2014). Sustainable procurement has been identified as one of the strategic tools that can resolve these issues to help the world move towards a more sustainable and resilient future (World Bank, 2019). Through sustainable procurement practices, organisations can meet their demand and supply of goods and services while minimising environmental harm, maximising financial returns, and enhancing socioeconomic status (Villena & Gioa, 2020; Bonnemaison, Eldandsson, Ibach & Spiller, 2021). This qualitative research used an Eastern Cape-based higher education institution in South Africa as a case study to investigate factors that influence adopting and implementing sustainable procurement, with resilience as a theoretical foundation, in higher education. The research obtained approval from the participating university as a gatekeeper for the study; it began by drafting a research proposal and securing ethical clearance from Rhodes University. Semi-structured interviews were used with seven higher education procurement staff members to get the data working in procurement in higher education. The findings from the study revealed that managerial support and knowledge of sustainable procurement were determining factors for whether or not a university developed and implemented a strategy for sustainable procurement.Secondly, the participants mostly cited barriers as inadequate financial resources resulting in limitations for the university, therefore partially implementing sustainable practices. Thirdly, the data revealed that university staff in procurement had a basic understanding of sustainable procurement. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2024

This qualitative research used an Eastern Cape-based higher education institution in South Africa as a case study to investigate factors that influence adopting and implementing sustainable procurement, with resilience as a theoretical foundation, in higher education. The research obtained approval from the participating university as a gatekeeper for the study; it began by drafting a research proposal and securing ethical clearance from Rhodes University. Semi-structured interviews were used with seven higher education procurement staff members to get the data working in procurement in higher education. The findings from the study revealed that managerial support and knowledge of sustainable procurement were determining factors for whether or not a university developed and implemented a strategy for sustainable procurement.Secondly, the participants mostly cited barriers as inadequate financial resources resulting in limitations for the university, therefore partially implementing sustainable practices. Thirdly, the data revealed that university staff in procurement had a basic understanding of sustainable procurement. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2024

- Description: This research study aimed to improve the alumni awareness of FGS at Sol Plaatje University in order to enjoy a lifelong connection with their alma mater. Furthermore, this study provides recommendations to Sol Plaatje University on how engage first-generation students (FGS) and alumni more effectively in the future. This study used a mixed-method research design to collect and analyse data. The first phase of data collection used a quantitative research method in the form of a survey to obtain biographical information about the final-year students and to identify FGS as key participants for this study. The second data collection phase employed qualitative research to gain insight into alumni awareness among FGS through an alumni awareness workshop and a follow-up questionnaire. The survey findings revealed that students needed to be informed about alumni and related activities on campus. In addition, all were eager to attend the alumni workshop in the second phase of the study. The study findings revealed that FGS showed improved knowledge of alumni and related activities after attending the alumni awareness workshop. They also indicated their willingness to attend university alumni events such as reunions, homecoming, and fundraising events after graduation. Recommendations include suggestions for Sol Plaatje University to identify FGS at registration and tailor its extracurricular and support programmes to cater for such students. The university should also introduce alumni awareness workshops to prepare students for life after graduation as alumni and for the world of work. Lastly, the university should develop a mentoring programme for its FGS and alumni at an earlier stage to help them transition into and out of the university. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2024

- Description: Guided by the disciplinary power and social comparison theories, this study sought to explore the perceptions of Instagram-related male body ideals amongst young, gym-going men enrolled at Rhodes University. Seven in-depth interviews were conducted, and the responses suggested that Instagram use shaped young men’s body-related perceptions in a variety of complex ways. The findings suggested that Instagram exposed users to a lean and muscular body ideal and that perceptions of this ideal were shaped by factors such as Instagram’s positivity bias, the age of users, and the exposure to the idealised bodies of fitness influencers. Furthermore, perceptions of Instagram’s male body ideal were influenced by context. Black South Africans that attended majority white high schools were more likely to conform to the male body ideals associated with their school environment. In such instances, individuals rejected the body norms associated with their ethnic backgrounds in lieu of striving for a lean and muscular body. Additionally, perceptions of body dissatisfaction were evident in cases where upward social comparisons were made with unrealistic male body ideals. Conformity to Instagram’s male body ideal also suggested that male users were subjected to a coercive form of power that resulted in their active participation in the reproduction of male body ideals. , Thesis (MSocSci) -- Faculty of Humanities, Sociology, 2024

- Description: Small and medium-sized enterprises (SMEs) are viewed as the cornerstone of socio-economic development in many economies globally. The progressive contribution of SMEs to the global economy is irrefutable and enshrined in poverty alleviation, inclusive economic growth, and job creation strategies pursued by many economies worldwide. SMEs are primarily the form of enterprise that accounts for over 90% of all businesses; thus, Small and Medium-sized Enterprises are the main source of employment. SMEs' contribution to value creation is estimated to be above 50% on average. In emerging countries, particularly South Africa, SMEs contribute approximately 45% of the total employment and 33% of the Gross Domestic Product (GDP). In most countries, Small and Medium-sized Enterprises contribute to more than 50% of employment and GDP, and these figures become significantly higher when the informal small business sector is included. World Bank estimated 600 million jobs needed by 2030, making SME development a high priority for many governments worldwide. Despite globally acknowledged SME contributions, small businesses are still faced with many challenges that have ramifications on their survival, growth, and performance. Studies highlighted challenges such as lack of access to finance and funding modalities, appropriate technology and infrastructure, markets and social networks, and lack of research and development, strategic management skills, and inability to perform managerial tasks, among others. Recent studies have been conducted on many of these challenges; however, there is little known about the strategic management challenges that face SMEs and their business performance. Several studies were conducted on some of these strategic management challenges, such as strategic planning, strategic orientation, strategic agility, organisational flexibility, and total quality management. However, a review of studies relevant to SMEs and their performance is silent on the argument regarding the influence of strategic leadership on the performance of SMEs, especially when key drivers of effective strategy implementation mediate strategic leadership. Thus, this study investigated the influence of strategic leadership on the performance of SMEs as mediated by strategy implementation in Nelson Mandela Bay (NMB). A detailed theoretical investigation was conducted on the nature and role of strategic leadership, strategy implementation, and business performance of SMEs. Strategic leadership represents the independent variables of this study, namely: strategic direction, balanced organisational controls, organisational culture, organisation’s resource portfolio, and ethical practice, followed by the mediating variable (strategy implementation) and the dependent variable (business performance). An empirical investigation was also conducted to test the significant influence between these variables. This study adopted a positivistic approach using a quantitative research method. The sample size of the study was 390 respondents. Self-developed and structured questionnaires were physically distributed to 315 SME owners and managers in NMB using a convenience sampling method. Only 229 returned questionnaires were suitable and relevant to this study; thus, a 72.69% response rate was achieved. Returned questionnaires were cleansed, coded, and transferred to a statistical data analysis software called Statistica, version 14.0, for quantitative data analyses. The validity and reliability of the measuring instrument were confirmed using Exploratory Factor Analysis and the calculation of Cronbach’s alpha coefficients. Descriptive statistics was calculated to summarise the empirical data on demographic variables and the main variables of this study. Pearson’s correlations were calculated to determine the correlations between the main variables of this study, and the results confirmed that there is a positive influence between strategic leadership, strategy implementation, and business performance of SMEs. A multiple linear regression analysis was conducted to test the significance of the influence between the main variables of the study. A regression analysis outcome revealed that some of the strategic leadership activities (strategic direction, balanced organisational controls, and organisational culture) have a statistically significant positive influence on the business performance of SMEs. Furthermore, a statistically significant positive influence does exist between strategy implementation and business performance of SMEs. This study’s recommendations were suggested to SME owners/managers. Firstly, to formulate and develop a clear long-term vision of the business for the next 3 to 5 years. Align resources to key areas of business operation and set internal controls that will help set standards of desired performance and ultimately achieve them. Secondly, to formulate and implement shared values that connect employees to the business purpose and the way it is conducted. These shared values must be underpinned by a unique, valuable, and incomparable culture against competitors to gain a competitive edge. Furthermore, consider using rewards to recognise employees who embody the shared values of the business and are committed to the success of the business because of its culture. Thirdly, ensure both strategic and financial controls support strategy implementation and guide employees to achieve performance objectives. Use balanced scorecards to assess the effectiveness of controls in the business and put corrective measures to address performance gaps. Last but not least, invest in staff development and training, technological infrastructure, and set sound processes and systems for the business operation, establish structures that have clear lines of reporting, authority, and delegation. , Thesis (MCom) -- Faculty of Commerce, Management, 2024

- Description: A tenet of the twenty-first century is the monetisation of everything due to commercialisation. The effects of this commercialisation have crept into every aspect of our lives, and although in the art world it has mostly been underhanded in its adoption, the traces of commercialisations touch are still evident in its functioning. Due to this underhandedness there hasn't been much thought put into what 'the monetisation of everything' truly implies for the industry, or how the value of the art object devoted to commercialisation may look like. The Private Collection (exhibition title of the practical component for submission in MFA completion) addresses the concept of object value and, more specifically, how that value is created within the art world through mechanisms of commercialisation that include celebrity cult, functioning of possession (through collecting), and taste. Research into Walter Benjamin's theory of the authenticity of the work of art, and in particular his concept of "aura," has helped inform the creation of a marketing strategy propelled by value driven mechanisms found within the Art Market for The Private Collection. Particular emphasis is placed on how brand value drives sales in this thesis. Thus, The Private Collection: Aura, the Cult of Celebrity, and the Construct of Value in Saleable Works of Art, defines The Private Collection as a tailored system built expressly for engagement with economic forces inside the art industry. As a result, the position of this study is based on the marketability of the object through particular driving forces that have seeped into the value system of the saleable work of art. The position of this thesis is that in this commercialist system, driving forces of value can be sustained within instances of the multiple. The project additionally supports this in maintaining that interaction from a fine art perspective would be limited if restricted to orthodox approaches (a gallery showing, and one print works), which is why a more economically interactive approach (e-commerce) was decided on for the exhibition component. The Private Collection offers an observation that the worth of a saleable work of art has become a warped representation of the commercial context we find ourselves in and that value is only awarded through particular kingmakers of the system.

- Description: The manufacturing industry is one of the greatest contributors to the South African economy. Owing to a competitive and complex automotive climate, it is suggested that only a few automotive manufacturing organisations will remain viable in the coming years, without the optimal reliance on human capital resources to navigate an unpredictable and unfolding landscape. In securing a sustainable future, the engagement of these human capital resources is necessitated. This competitive landscape has resulted in the call for adaptive and flexible leadership. Leadership behaviour is categorised into three streams, namely, transformational leadership, transactional leadership, and non-leadership, which is referred to as laissez-faire leadership. Employee engagement is defined as the extent to which an employee is committed to, and involved in, their operational function and the organisation, whilst portraying a willingness to perform and contribute beyond that which is expected of them. The purpose of this research was to explore the relationship between leadership and employee engagement in an Original Equipment Manufacturer (OEM) in South Africa. This OEM operates in the Eastern Cape and Gauteng Provinces of South Africa. Globally, the OEM launched a leadership journey to facilitate a shared value system that supported a vision towards organisational success, by focusing on transformed ways of working and acting, as a global collective team. The outcome of this desired journey yielded eight Leadership Principles. These Leadership Principles are referred to, and included in the research study, to gain a more robust internal perspective of the leadership behaviours that are most advocated within the OEM, in relation to employee engagement. The objective of this research therefore was to establish the relationship between leadership and employee engagement in the respective OEM, by investigating the impact of transformational leadership and transactional leadership on employee engagement. A triangulation approach was adopted to analyse the data, using a combination of qualitative and quantitative research methodologies. The result when testing the reliability coefficient scores of the leadership instrument described a poor measure for transactional leadership, and a good measure for transformational leadership. Therefore, the results that stemmed from the statistical analysis in relation to transactional leadership could not be trusted. However, in the context of this research, it was found that there is a statistically significant relationship between transformational leadership and employee engagement. Whilst utilising the qualitative research methodology, it was found that there is a limited definition-based relationship between transactional leadership and the eight Leadership Principles. However, there is a definition-based relationship between the Leadership Principles and transformational leadership, owing to similarities found in the definition descriptions between at least six of the eight Leadership Principles. In the investigation of whether there is a definition-based relationship between the Leadership Principles and employee engagement, it was found that a limited definition-based relationship between the eight Leadership Principles and engagement existed. The research therefore met its objectives in determining a relationship between leadership and employee engagement in an Original Equipment Manufacturer in South Africa. , Thesis (MCom) -- Faculty of Commerce, Management, 2024

In the investigation of whether there is a definition-based relationship between the Leadership Principles and employee engagement, it was found that a limited definition-based relationship between the eight Leadership Principles and engagement existed. The research therefore met its objectives in determining a relationship between leadership and employee engagement in an Original Equipment Manufacturer in South Africa. , Thesis (MCom) -- Faculty of Commerce, Management, 2024

- Description: Globally, several empirical studies have demonstrated the ability of the yield spread to predict a recession in a country. In South Africa, previous studies have not only shown the yield curve's predictive power but have further demonstrated that it outperforms other commonly used variables, such as the growth rate of real money supply, changes in stock prices, and the index of leading economic indicators. However, some recent studies have shown that the yield spread (the spread between 10-year bonds and 3-month Treasury bills) gave false signals of recession. In this study, we explore the possible reasons for the false signals of the yield spread by addressing the following questions. Does the yield spread used matter? Does the measure of the business cycle used matter? And do the estimation techniques used matter? To address the first question, unlike the previous studies, this paper uses four different yield spreads- depicting short-term, medium-term, and long-term government bonds against the backdrop of a changing structure of bond holding, which reflects the increasing risk eversion of investors in South Africa. Second, the paper used different measures of business cycles, namely industrial production index, lagging, coincident, and leading economic indicators. The empirical models were estimated using both univariate and multivariate Markov switching models. As economic theory suggests, the univariate Markov switching model was used to determine if each variable exhibits a significant regime switching. The multivariate Markov switching model was estimated for each business cycle and yield spread variable, with each of the other variables serving as a non-switching explanatory variable, thereby addressing potential endogeneity concerns and the predictive power of the explanatory variable. Finally, the multivariate Markov switching model was estimated for three monthly sample periods, a full sample for 1986 to 2022, and two sub-samples – 1986 to 2009 and 2010 to 2022. This analysis consistently reveals significant regime-switching behavior across all the series thus, affirming the superiority of the regime switching model over the standard model used in previous studies. By analyzing the transition probabilities and the expected durations between these regimes, we find that including the spreads in the business cycle model improves the models’ predictability, with the medium-term bonds spread performing better than the usual long-term spread. The smoothed regime probability of the best-performing models is compared with the SARB recession dates; the two closely resemble each other, proving that the Markov switching model can help predict the turning points in the business cycle in South Africa. , Thesis (MCom) -- Faculty of Commerce, Economics and Economic History, 2024

- Description: Genealogy is the study of family history. Family trees are used to show ancestry and visualise family history. Animal family trees are different from human family trees as animals have more offspring to represent in a family tree visualisation. Auctioneering organisations, such as Boere Korporasie Beperk (BKB), provide livestock auction catalogues containing pictures of the animal on sale, the animal’s family tree and its breeding and selection data. Modern-day farming has become data-driven and livestock farmers use various online devices and platforms to obtain information, such as real-time milk production, animal health monitoring and to manage farming operations. This study investigated and compared two Business Intelligence (BI) platforms namely Microsoft Power BI and Tableau (Salesforce) and the Python programming language used in the implementation of cattle family tree charts. Animal family tree visualisation requirements were identified from analysing data collected from 23 agriculture users and auction attendees who responded to an online questionnaire. The results of an online survey showed that agriculture users preferred an animal family tree that resembled a human one, which is not currently used in livestock auction catalogues. A conference paper was published based on the survey results. The Design Science Research Methodology (DSRM) was used to aid in creating animal family tree charts using Power BI, Tableau and Python. The author compared the visualisation tools against selected criteria, such as learnability, portability interoperability and security. Usability evaluations using eye tracking were conducted with agriculture users in a usability lab to compare the artefacts developed using Power BI and Python. Tableau was discarded during the implementation process as it did not produce the required family tree visualisation The Technology Acceptance Model (TAM) theory, which seeks to predict the acceptance and use of technology based on users' perception of its usefulness and ease of use, was used to guide the research study in evaluating the artefacts. According to TAM, the adoption of the proposed technology to solve the problem of a static animal family tree in livestock auction catalogues was dependent on the agriculture user’s beliefs. This was based upon that the technology would help them make better buying decisions at livestock auctions effortlessly. The other theory used in this study was the Task Technology Fit (TTF). This theory was used mainly to create the task list to be used in the usability test. The results showed that the author of this work and the agriculture users preferred the artefact produced by Power BI. The learnability and development time was shorter and the User Interface (UI) created was more intuitive. The findings of this study indicated that the present auction catalogue could be supplemented using interactive online animal family tree visualisations created using Power BI. This study recommended that livestock auctioneering organisations should, in addition to providing paper catalogues, provide farmers with an online platform to view the family trees of cattle on auction to enhance purchasing decisions. , Thesis (MCom) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2024
