  • Description: The increase in female participation in sport has led to an increase in research reporting on the relationship between fitness and menstrual cycle (F&M) data. Fitness variables such as VO2 max and heart rate are influenced by menstrual hormones and change with the different phases of a cycle. People frequently track both their F&M data, to understand their long-term activity and their body’s changes during the different cycle phases. Both these data sets are tracked and visualised separately to help people understand their data, however little work has been done to visualise the relationship between the two data sets. A process that guides the creation of an integrated F&M visualisation does not exist. This research aimed to develop and adopt a process that could be used to successfully guide the creation of an integrated F&M visualisation. The study followed the Design Science Research Methodology (DSRM) to create a primary and secondary artefact – the process and instantiation thereof. The DSRM was applied in iterative cycles where the process was developed, instantiations created and evaluated by participants. To develop the process, existing data processing and visualisation processes were reviewed from literature, to assess their successes and shortcomings. The review of existing processes revealed what steps, and factors related to those steps, would need to be considered. The process review highlighted the importance of five process steps: planning, collection, access, integration, and visualisation. Once the conceptual process was designed, it was adapted for the goal of creating an integrated F&M data visualisation. Prior to implementation, the process was first tested in a pilot study to ensure its validity before involving participants in data collection. After the process pilot study, the final implementation of the process took place and participants were recruited. In the first step of the process, the different fitness data types that are influenced by the menstrual cycle, and vice versa, were identified through a literature review. In the second step, devices to be used for data collection were evaluated and tested through exploratory testing and review of user manuals available online. The third and fourth steps, access, and integration were informed by further exploratory testing and review of relevant literature. The fifth step, data visualisation, was guided by relevant studies, Hick’s law, and the Schema Theory. Two Iterations of DSR were conducted in two phases. Phase 1 (P1) was the instantiation of the planning, collection, access, and processing steps. Participants wore smartwatches while going about their daily lives and working out and tracked their menstrual cycle to collect data. P1data was used to create several instantiations of the process. The second phase (P2) was the instantiation the visualisation step. The final visualisations, resulting from the instantiations, were evaluated by participants in P2. The review notes were used to improve both the process and the final visualisations. Both P1 and P2 were repeated (iterated) twice. The recommended process can be used by anyone who wants to create an integrated F&M visualisation and was designed to be modular so that users could choose to follow the whole process or only specific steps. The findings of this research can provide guidance to users, developers and smartwatch manufacturers of what people’s preferences are for these integrated visualisations. It also provides guidance for those who wish to create their own visualisations without needing prior programming experience or knowledge, since easy to use, online visualisation tools are recommended. The process instantiations will assist people, especially women, to better understand their menstrual cycle and how it affects their physical well-being. , Thesis (MCom) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2024

  • Description: A racially segregated culture historically influenced the growth of psychological testing and evaluation in South Africa. Thus, South Africa's multicultural and multilingual community poses difficulties for psychologists in their daily work. Most of the psychological tests used by psychologists are predominantly normed in either or only English/Afrikaans. Given the economic and professional resources required to develop new standardised tests for the broader South African population, the current status quo is set to continue for the foreseeable future. Consequently, language barriers pose a challenge when psychometric standardised tests are administered in a language that is different from that of the client, and as a result, psychologists must develop ways to enhance the fairness of these measures for their client base. The avenue of research that was explored is how psychologists overcome the language boundary when assessing clients who speak an indigenous first language, particularly isiXhosa. As such, this study explored this question through qualitative methods. Through purposive sampling, nine psychologists were invited to share their practical expertise on this topic, using semi-structured online interviews. The findings of this study suggested several core themes providing useful methods for other psychologists facing the same challenge, including the challenges with administering psychological tests with isiXhosa clients, the availability of standardised tests in the South African context, and the importance of determining the client’s language proficiency. Five themes with several sub-themes emerged from the study. The study contributes to the currently limited existing body of knowledge, and subsequently to the research area that this study explores - thus further providing guidelines that practitioners can employ when working with clients who are isiXhosa speaking. , Thesis (MA) -- Faculty of Health Science, School of Behavioural & Lifestyle Sciences, 2024

  • Description: The outbreak of the Covid-19 pandemic affected the whole world. Consequently, countries were forced to lock down and citizens had to be quarantined to control the spread of the virus. Accordingly, the World Health Organization (WHO) came up with safety measures to try and mitigate the spread of the virus. These measures included Covid-19 health communication, and this communication was transmitted mostly through the media. However, this crucial health communication was mostly conveyed in English. The cascading of the Covid-19 health communication in English proved to be problematic worldwide especially for linguistically diverse countries like South Africa. As a result, the South African government had to put measures in place to ensure that the health communication regarding Covid-19 could reach every citizen in the country by commissioning translation services to urgently translate terms relating to Covid-19 into all the South African indigenous languages including isiXhosa. Hence the South African government and City of Tshwane decided to enlist the services of the South African Centre for Digital Language Resources (SaDiLaR) and the Pan South African Language Board (PanSALB) to translate the Covid-19 terminology into all the indigenous languages spoken in the country. This study therefore aims to examine the quality and the accuracy of the translated Covid-19 terms into isiXhosa especially since the translation of these terms had to be done urgently. The study will follow a qualitative method approach and use the skopos theory as the lens of the study. Skopos refers to purpose, intention, and aim. The theory is known as a purpose for action and the reader in this theory is important in determining the purpose of the translation at hand. In evaluating the terminology that has been translated the theory will be applied to determine whether the purpose and the aim of the terminology was adequately carried out to the intended audience. The English terms and isiXhosa terms collected in this research which will be analysed are sourced from the material that was developed and compiled by SaDiLaR and PanSALB and subsequently cascaded to the public during the Covid-19 pandemic. The study will analyse only the (75) translated isiXhosa terms. , Thesis (MA) -- Faculty of Humanities, School of Language, Media and Communication, 2024

  • Description: Information Security Management System (ISMS) is a set of processes to protect institution information assets and information and to preserve confidentiality, integrity, and availability of institutional information. In the world of computers, it is known that there is no silver bullet when it comes to protecting an IT infrastructure. At some point, an organisation will face a security breach, and how it deals with the information security incident depending on the robustness of its processes and the strategy for handling incidents. In today’s world, information communication and technology (ICT) is integral in automating manual tasks that can take hours and even days to execute. The more institutions depend on technology, the more they become vulnerable to cyber threats. This could result in an institution losing its competitive edge, facing legal issues, loss of reputation, customer confidence and productivity, and lastly, financial loss. Various information security standards, frameworks, and methodologies can be applied to protect information assets. Many of these best practices define the ‘what’ and not the ‘how’ making it even more complex for institutions such as Higher Education to implement ISMS. The study aims is to develop a strategy for handling information security incidents that Higher Education Institutions can follow to improve how incidents, cyber threats and breaches are handled. The primary research objective is addressed through several secondary research objectives, namely, to investigate current strategies that Higher Education Institutions can utilise for the handling of information security incidents, to understand various challenges that Higher Education Institutions encounter when handling information security incidents, to assess the current capacity of relevant personnel in handling information security incidents through semi-structured interviews. A detailed literature review was undertaken to delve into existing various information security standards, frameworks, and methodologies. In addition, an investigation was conducted on ISMS adoption and implementation by institutions and Higher Education Institutions in general and how modern best practices such as ISO2700x, COBIT, ITIL, NIST, etc, relate to ISMS. Furthermore, semi-structured interviews were conducted to determine information security incidents at South African Higher Education Institutions. Expert interviews are utilised to evaluate the proposed strategy and provide input. The literature review findings, together with results obtained from semi-structured and expert interviews, are used to develop a strategy evaluated for its robustness, effectiveness, and suitability for the purpose. The developed strategy can be considered a beneficial tool for Higher Education Institutions in South Africa for handling information security incidents. This study’s findings significantly contribute to ISMS research in Higher Education Institutions in South Africa. In conclusion, findings of the study can be summarized as follows. The first chapter, which is also an introduction, sets out the scene for the entire research study undertaken by first highlighting information technology as an integral part of any business nowadays. Higher education institutions collect, process and store sensitive information of current and prospective students and employees, which might be of value to hackers. An information security management system (ISMS) can minimise damage by ensuring information assets are protected from a wide range of threats and business resilience in case of a breach or an incident. Chapter 2 reviews the existing literature for these frameworks, standards, and methods. In addition, various ISMS challenges and limitations within Higher Education Institutions were explored. The third chapter outlines the research design process and an emphasises that it must be based on real-world or tangible challenges. The fourth chapter presented and discussed results that were obtained from semi-structured interviews. The study’s analysis and findings vividly show that there is a need to implement a strategy to handle information security incidents for South African higher education institutions. The strategic management approach used to formulate a strategy to address the identified real problem is discussed in detail in chapter 5. The strategy is developed based on the information gathered from the literature review and semi-structured interviews. The results of the assessment of the proposed strategy carried out by the experts are presented in Chapter 6.The chapter also includes recommendations made by the experts to improve the proposedstrategy. , Thesis (MPhil) -- Faculty of Engineering, the Built Environment and Technology, School of Information Technology, 2024

  • Description: Effectively managing information technology (IT) resources has become a significant concern for organizations, both large and small, as they conduct their business operations. IT governance, characterized as the decision-making process ensuring alignment with business strategy, optimal utilization of IT assets, and the effective management of risk and organizational value, plays a crucial role in addressing this concern. Within this landscape, an IT shared services model emerges as a strategic approach to develop, maintain, and deliver innovative services, thereby enhancing effective and efficient service delivery. This model is perceived to not only innovate services but also to liberate other departments, enabling them to focus on their core competencies. This study positions IT governance as a comprehensive umbrella process that guides the implementation of IT shared services. A well-guided implementation of IT shared services is anticipated to contribute significantly to the success of IT projects, ultimately benefiting all activities supported by these services. The implementation of shared IT services in academic tertiary institutions is not well documented or discussed. This study thus is done in such an academic context. This study focuses on developing a strategic framework for the implementation of IT Shared Services at tertiary education providers. The specific case study used for the development of the strategy is Nelson Mandela University. The scope of the project focuses on the development, proposal, and expert review of a strategy for implementing IT shared services effectively in alignment with Governance Practices. The practical implementation of the strategy falls beyond the scope of this study. , Thesis (MPhil) -- Faculty of Engineering, the Built Environment and Technology, School of Information Technology, 2024

  • Description: As finding employment in South Africa remains difficult, venture creation is a necessary alternative source of income and employment. The literature suggests that a university should serve as an incubator for student entrepreneurs and provide a supportive environment for their entrepreneurial ventures. Universities are also important to the development of entrepreneurial thinking among faculty, students, and other stakeholders. Furthermore, a university-based entrepreneurial ecosystem (U-BEE) is perceived as a source of support for successful student start-up ventures. The literature suggests that the elements of U-BEEs and the interaction between them vary depending on regional and local conditions. Furthermore, the key components of a U-BEE are not appropriate for all regions or contexts. As U-BEEs are dynamic and student start-ups vary, the need exists to understand the interacting elements of the system before it can be built, or the strategies implemented. Against this background, the primary objective of this study was to map and assess a student U-BEE in a developing country context. The current study was situated in an interpretive research paradigm and deductive reasoning was applied. As a single case study research strategy was used and based on convenience sampling, Nelson Mandela University (NMU) was selected as the case to be investigated. Data was collected through a document review, surveying 33 respondents as well as conducting semi-structured interviews with 12 entrepreneurship stakeholders at one point in time. Deductive codes and thematic analysis were used to analyze the data. Through identifying and delineating the elements of NMU’s student U-BEE, it was noted that the elements in the system varied in degree of importance and prevalence. The elements investigated were people, infrastructure, funding, leadership and governance, entrepreneurship activities, reward system, collaboration, monitoring and evaluation, as well as organizational culture and outcomes. Several people were identified as supporting student entrepreneurship at NMU ranging from top management, and academics to support staff. Although a science and technology park did not exist at NMU, the findings showed that physical infrastructure and IT facilities existed to support student entrepreneurship. Despite some funding being provided for student entrepreneurship support (SES) development, none was provided for entrepreneurial infrastructure. Some top management personnel were identified as providing leadership for SES at NMU including the Vice-Chancellor who was committed to contributing to the ecosystem. In addition, various co-curricular SES activities were identified as taking place at NMU with most being offered free to registered students. However, NMU did not provide any incentives to encourage staff or students to provide SES at NMU and no formal system for rewards existed. Several internal and external collaborations to provide SES activities effectively at NMU were identified, with most occurring through the Entrepreneurship Development in Higher Education Community of Practice Network. SES activities were not monitored at NMU, but some student entrepreneurship data was handled by the Department of Institutional Planning. As a result, NMU was not perceived as having an entrepreneurially supportive culture, and the use of metrics to establish measurable outcomes were limited. In addition to identifying the challenges faced when building a student U-BEE ecosystem in a developing country context, the study elaborated on several suggestions on how these challenges could be overcome and what improvements could be made in terms of SES at NMU. The challenges identified related to NMU being under-resourced in terms of funds, staff, and infrastructure to support student entrepreneurship. In general, the findings of this study highlighted the need for student entrepreneurship to be a strategic priority at NMU. The increased involvement of top management, entrepreneurship staff, students, and other stakeholders needs to be encouraged and incentivized. In addition, faculties across the university should encourage student entrepreneurship involvement and encourage students to participate in programmes offered on campuses. The importance of appropriately skilled staff to handle all matters relating to student entrepreneurship was also emphasized. This study has theoretical significance because it identifies, maps, and assesses the elements of a student U-BEE in a developing country context. As such, it paves the way for future researchers to investigate other universities in these contexts, and to undertake further empirical studies. This study also has practical significance in that it makes several recommendations that might be of value to stakeholders within U-BEEs in developing country contexts. , Thesis (MCom) -- Faculty of Business and Economic Sciences, School of Management Sciences, 2024

  • Description: Youth unemployment is a persistent and pressing challenge faced by communities and governments worldwide. In Buffalo City Metropolitan Municipality, a region characterised by its diverse socioeconomic landscape and unique set of opportunities and constraints, the issue of youth unemployment is of particular concern. The Isiqalo Youth Fund was established as a strategic initiative to address this challenge and promote economic empowerment and employability among the youth. This fund was designed to provide financial support and resources to young individuals in the municipality, offering them the opportunity to gain the skills, training, and experience required to enter the workforce and make meaningful contributions to the local economy. The study aimed to assess the implementation of the Isiqalo Youth Fund, which aims to facilitate youth employment in Buffalo City Metropolitan Municipality. The study utilised the qualitative research methodology, and the sample was selected using a purposive sampling technique. The sample for this study comprised ten youth beneficiaries of the Isiqalo Youth Fund, five officials from the Office of the Premier, and five officials from the Department of Economic Development, Environmental Affairs and Tourism (DEDEAT) responsible for the administration and oversight of the fund. Semi-structured interviews were conducted to capture the experiences and perceptions of the youth beneficiaries and the insights of the officials involved in the implementation of the Isiqalo Youth Fund. The study’s findings from the beneficiaries’ perspective indicate that accessing the Isiqalo Youth Fund is associated with several challenges, such as high levels of bureaucracy, poor fund management, a lack of information, lack of proper monitoring and evaluation mechanisms, and complex application procedures. The findings from the administrators’ perspectives indicated that a lack of ethics, fair dealing, and accountability adversely influenced the effective administration of the Isiqalo Youth Fund. The study recommends that local authorities and stakeholders collaborate to simplify the application process, improve fund management, increase awareness, offer support and mentorship, and enhance project monitoring and evaluation. , Thesis (MA) -- Faculty of Humanities, School of Public Management and Leadership, 2024

  • Description: The central aim of this study was to assess the engagement of supply chain stakeholders, namely OEMs and an automotive supplier, in relation to customer-specific requirements. This objective was accomplished by identifying the communication methods employed by both parties for addressing customer-specific needs. Additionally, the study aimed to pinpoint the factors that promoted engagement between OEMs and automotive suppliers concerning these requirements. Conversely, it aimed to uncover the factors that hindered such engagement. Lastly, the research aimed to evaluate whether this engagement effectively alleviated the pressures faced by the automotive supplier regarding customer-specific requirements. The broader goal of the research was to comprehend how supply chain stakeholder engagement operated between OEMs and an automotive supplier with respect to customer-specific requirements. This was pursued through secondary objectives, which entailed examining how communication transpired between OEMs and an automotive supplier, the degree of participatory nature in this communication, the barriers and catalysts influencing customer-specific requirements, and whether this engagement mitigated the pressures borne by the automotive supplier. These objectives were instrumental in revealing opportunities for enhancing OEM communication, thereby positively contributing to their relationships with supply chain partners and mitigating the added burdens they faced. The research followed a qualitative case study design, utilizing semi-structured interviews to delve into the experiences of participants carefully selected from an automotive supplier. These participants were chosen based on their interactions with OEM customers, thereby providing pertinent insights into these interactions. Thematic analysis was employed for data analysis, uncovering codes, categories, and overarching themes from participants’ responses. The findings of the research highlighted certain consistent themes, shedding light on which communication methods were employed more frequently, as well as the rationale behind their usage. Notably, online platforms emerged as a popular channel, and daily communication was preferred. The research also revealed a recurring theme wherein OEMs assumed a controlling role, rather than fostering a mutually advantageous partnership in addressing issues. Additionally, communication barriers were observed in the use of online portals for communication by the automotive supplier. In these themes, variations were discerned in communication channels. These differences were rooted in participants’ responsibilities, decision-making authority, and designated roles. Consequently, the perception of communication channels varied among participants. However, similarities were also noted in the participants’ feedback regarding communication channels. The research highlighted the necessity for improved two-way communication and emphasized the need for a collaborative approach between OEMs and the automotive supplier, rather than a unilateral one. The research underscored an evident power imbalance between OEMs and the automotive supplier. In essence, the crux of a successful and mutually beneficial engagement between OEMs and the automotive supplier lies in transparent communication, adaptability, and a shared willingness to find solutions that cater to both sides. By focusing on these core principles, it is plausible to establish a scenario that benefits both parties and nurtures a robust and enduring partnership. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2024

  • Description: Cancer is a disease caused by uncontrolled growth and spreading of abnormal cells to distant body parts. Approximately 19.3 million and 10 million new cancer cases and cancer deaths, respectively were recorded in 2020. Despite advancements in prevention and therapeutic strategies, cancer remains a global health problem. Cancer patients are increasingly seeking complementary and alternative medicines, of which herbal medicines are the most common form of CAM used by patients. Numerous in vitro and in vivo studies of herbal medicines in cancer have shown that they have antioxidant and anticancer (antitumor and anti-proliferative) properties. While concurrent use with conventional cancer treatments may improve treatment efficacy, alleviate chemotherapy-related side effects, boost the immune system, or impede drug resistance, it can also prompt drug-herbal interactions, and this may affect the pharmacodynamics and pharmacokinetics of the chemotherapeutic drug. This study aimed to determine relevant pharmacodynamic interactions with chemotherapeutic drugs and investigate such interactions' mechanisms. The objectives of the study were to screen the cytotoxicity effects of drug compounds, herbal extracts, and drug-herb combinations, to determine the ability of treatments to induce apoptosis, and to determine the most beneficial treatment. The cytotoxic effects of cisplatin in HeLa cells, tamoxifen in MCF7 cells, 5-fluorouracil in Caco-2 cells, and grapeseed, green tea, fermented rooibos, and green rooibos in all the listed cell lines were evaluated individually and in combination using the bis-Benzamide H 33342 trihydrochloride/propidium iodide (Hoechst 33342/PI) dual staining method. CompuSyn 1.0 Software was used to quantify synergism and antagonism. The mechanism of apoptosis induction of the different synergetic combinations, drug compounds, and herbal extracts was illustrated by quantitative fluorescence image analysis, specifically cell cycle analysis, phosphatidylserine translocation, mitochondrial membrane potential analysis, caspase 3 activation, and reactive oxygen species production using the relevant contrast dyes. Grapeseed displayed cytotoxicity towards MCF7 and HeLa cells (IC50 57.98 and 83.28 μg/mL, respectively). Green tea was only cytotoxic against HeLa cells at an IC50 of 91,92 μg/mL. None of the extracts displayed cytotoxicity against Caco-2 cells (IC50 values > 200μg/mL). If the herbal extracts had inconclusive IC50 values in the three cell lines subsequent experiments were conducted using 100 μg/mL. The results showed that most of the combinations were antagonistic but, some combinations had synergistic or enhancement effects(1:3 for cisplatin with grape seed or green tea and tamoxifen with grapeseed or green tea, and 3:1 for cisplatin with green tea as well as for tamoxifen with fermented rooibos or green rooibos, and all the 1:1 combinations of 5- fluorouracil with all herbal extracts) with a combination index (CI) < 1. Grape seed and green tea were found to induce apoptosis in the three cell lines. Assays that were conducted to detect apoptosis induction showed positive staining for phosphatidylserine (PS), activated caspase 3, and reactive oxygen species (ROS), mitochondrial membrane depolarization. Analysis of the cell cycle showed two things; 1) that grape seed and green tea were apoptotic in HeLa and MCF7 cells only, and 2) the extracts of green tea and green rooibos, and the combinations of grape seed with all drug compounds arrested the cell in more than one phase of the cell cycle. The combinations of grapeseed and green tea potentially induced apoptosis in various manners but those with both rooibos extracts were unclear in all the cell lines. The results for combinations with grapeseed and green tea are promising and provide a basis for further research as combinations of chemotherapeutic drugs and herbal extracts may be effective therapeutic strategies. , Thesis (MPharm) -- Faculty of Health Sciences, School of Clinical Care & Medicinal Sciences, 2024

  • Description: Breast cancer constitutes 23% of all cancers in South African females. Curcumin and Nigella sativa have anti-cancer, anti-metastatic and antioxidant-properties and may be effective against breast cancer. This study focused on the effect of N. sativa extracts or thymoquinone and curcumin, individually and in combination, on breast cancer cells. An MTT assay showed that curcumin reduced cell viability by 50% (IC50) at 18 ± 2.63 μg/mL and thymoquinone (TQ) at 5 ± 0.95 μg/mL against the MDA-MB-231 cells. The IC50 values for curcumin and TQ were 35 ± 6.98 μg/mL and 4 ± 0.96 μg/mL against the MCF-7 cells, respectively. The IC50 value for the NSBE was determined to be 350 ± 55 μg/mL. The IC50 value of NSAE did not fall within the selected concentration range. Synergism was noted for combinations of NSBE with curcumin, and combinations of TQ with curcumin, against both MCF-7 and MDA-MB-231 cells. Two synergistic combinations per treatment per cell line, as determined by the combination index analysis, were chosen for further investigation. The combinations and individual treatments tested against the MCF-10A cells, were not significant, except for NSBE80:CURC20 combination. Curcumin had the most significant anti-oxidant activity; however, no link was noted between the anti-oxidant activity and the cytotoxicity of the combinations. The combination treatments induced apoptosis more effectively than the individual treatments. Caspase-3 dependent apoptosis was noted for NSBE10:CURC90 and TQ80:CURC20 combinations against the MDA-MB-231 cells, and the TQ60:CURC40 combination against the MCF-7 cells. The individual and combined treatments effectively reduced MDA-MB-231 cell adhesion to fibronectin, but not all reduced the cell adhesion to laminin. Based on these results, the combinations of curcumin with TQ or NSBE, have promising anticancer benefits against breast cancer. , Thesis (MSc) -- Faculty of Science, School of Biomolecular & Chemical Sciences, 2024

  • Description: Mathematics in South Africa is one of the subjects that is considered ‘difficult’ by many learners. The proof of this statement is reflected by the low mathematical pass rate in many South African schools. One of the challenges that has been highlighted by learners and teachers is that the language of mathematics is challenging. This implies that learners find it difficult to understand some of the mathematical terminologies and content that is being taught. The main reason for the challenge of grasping mathematical terminologies that has been cited by learners and educators is the language of learning and teaching (LOLT). Mathematics is taught in English in most South African schools even though many learners speak one of the indigenous South African official languages (if one excludes English and Afrikaans) at home and get to use and be exposed to English as the medium of learning and teaching only at school. While mathematics remains a challenge in South Africa, research shows that when home languages are used in a mathematics classroom, it enhances the learners understanding. However, it is not always simple to transfer mathematics from English to an African language. There are complexities associated with translation that include the lack of vocabulary in the target language which in this case is Xitsonga. The lack of terminologies in Xitsonga is one of the challenges that occur during the process of translation. This purpose of this research is to examine the challenges of translating mathematical terminologies from English into Xitsonga and to find the strategies that can be used to assist learners to improve their understanding of mathematics. As such, a qualitative research method will be used to select the mathematical terminologies extracted froma mathematics bilingual dictionary with the aim of examining the quality of the translation and identifying the challenges that have been experience by translators. , Thesis (MA) -- Faculty of Humanities, School of Language, Media and Communication, 2024

  • Description: The catalytic converter industry plays a crucial role in enhancing the sustainability of automotive and industrial processes by mitigating the environmental impact of harmful emissions. Catalytic converters are devices that use catalysts to facilitate chemical reactions, converting the pollutants in exhaust gases into less harmful substances. It has become necessary to investigate the current and future state of the catalytic converter industry, due to the stringent emissions regulations being adapted across the world, including the introduction of alternative powered vehicles. The primary objective of this study is to identify sustainable strategies that could be adapted by the catalytic converter industry to ensure sustainability of the market. The study was conducted using a qualitative phenomenological approach. A total of 12 participants were chosen for the study and in-depth interviews were used as data collection tool to accomplish the objectives of the study. A thematic qualitative data analysis approach was taken to analyse and identify emerging themes from the collected data. As the industry is extremely dynamic, it becomes very difficult to update data for analysis purposes, therefore it becomes complicated to challenge the growth opportunities for the industry. It is therefore recommended to conduct thorough market analysis considering factors, such as market trends, regional variations, key players, and supply-demand dynamics. A deeper dive into the influences of the electric and hydrogen technologies’ effect on the catalytic converter industry, is key to identify potential opportunities and challenges associated with the move to greener transportation. The findings of this study established that the catalytic converter industry should adopt a multifaceted strategy, that includes regulatory compliance, technological innovation, environmental responsibility, and a willingness to adapt to shifting market dynamics. The ability of this industry to strike a balance between environmental stewardship and economic viability, will determine its future success. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2024

  • Description: The advent of the digital age provided businesses with new opportunities and ways of doing business digitally. Digital commerce encompasses many aspects, one of which is electronic commerce (e-commerce). Due to the rise of e-commerce, the retail industry specifically has undergone a significant transformation, with e-commerce offering new business models to companies. E-commerce retailers like Amazon, TakeAlot, eBay, and Alibaba have successfully developed online stores and disrupted the traditional face-to-face retail trade. Brick-and-mortar retailers, once the dominant force, now find themselves in an increasingly competitive environment. The agriculture retail sector is no different and new disruptions and opportunities caused by e-commerce necessitated the agriculture retail sector to also consider e-commerce’s impact and implement changes where necessary. The COVID-19 pandemic further disrupted the traditional methods of doing business due to lockdowns and social distancing measures implemented by governments globally. COVID-19’s impact along with a changing business environment, inclined an agriculture retailer in South Africa, the Humansdorpse Landbou Koöperasie, trading as The Co-Op, to explore e-commerce as a new business model to support and enhance their customers purchasing experience. The aim of this study is to determine the factors that influence the adoption of an online model for an agriculture retailer in South Africa. A literature review on e-commerce and the agriculture retail sector was conducted, and from the literature a conceptual model was proposed, which identified the main factors that influence the adoption of an online model for an agriculture retailer. A questionnaire was developed and translated into three languages - Afrikaans, English and IsiXhosa - and distributed to customers of The Co-Op. The results obtained from the questionnaire were statistically analysed. After conducting correlation and Chi-Square tests the relationship between the identified independent factors and the dependent factor was determined. The study identified that the independent factors of: Acceptance of Internet Technology, Online Shopping, Delivery, Methods of Payment, and Product Range positively influence the dependent factor, the Co-Op Online Shopping and thus the adoption thereof. The study thus confirmed the need for an online model for The Co-Op. The study contributes theoretically by discussing agriculture retail and technology acceptance within the realm of the Technology Acceptance Model and the Theory of Planned Behaviour. The study’s practical contribution includes a tested hypothesised model that can be used for future research by other agriculture retailers. Additionally, research on this topic can be expanded to other agricultural retailers in South Africa and Africa. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2024

  • Description: Banking institutions promote loyalty programmes that offer customers cost saving benefits. The research investigates the perceived loyalty programme benefits from a customer perspective. The research analyses the customer satisfaction and the effect the banking loyalty programmes has on customer behaviour post Covid-19. Focusing on customer retention and customer relationship management, banking institutions have adopted loyalty programmes as a strategic tool to enhance customer loyalty and satisfaction. The findings of this research provided valuable insights into the key factors that drives customer loyalty and engagement with banking loyalty programmes. This study used quantitative research methodology utilizing surveys and statistical analyses to gather and interpret data using simple random sampling from a diverse sample of banking customers from the Gqeberha area. A response rate of 50.5% was achieved in this study. The findings of this study underscore a pivotal realisation that banking loyalty programmes in isolation prove insufficient to exert a significant influence on banking customer behaviour in the post-Covid era. A contemporary approach is required to meet the evolving expectations and dynamics within the customer base. The study observed that digital transformation and strategic partnerships are a key determinant in shaping banking customer behaviour, hence the study advocates for a synergised approach, where banking loyalty programmes, digital transformation, and strategic partnerships operate in tandem. It is recommended that banks should understand the dynamics of consumer behaviour in the context of loyalty programmes, hence they can optimize their strategies to strengthen their position and relationships with their customers. Traditional silos of banking loyalty programmes must integrate and adapt to the current banking customer preferences, this holistic approach is not just a recommendation but also imperative for sustainable growth and resilience in the banking sector. The study will contribute to academic research and offer practical implications for banking executive seeking to build, design and implement effective loyalty programmes in a highly competitive banking industry. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2024

  • Description: In today's world, technology has changed how people live and behave. The influence of technology contemplates a similar change in the education processes of teaching and learning. Many governments worldwide invest hugely in providing technological tools and facilities and training teachers to improve teaching and learning. The availability and access to technologies in schools seem to offer teachers opportunities to develop technological knowledge and integrate technology into teaching. Literature indicates that teachers must possess technological pedagogical content knowledge (TPACK) to integrate technology into teaching and learning processes effectively. However, other scholars have also suggested that teachers' TPACK develops and is shaped by many contexts. This study, therefore, sought to assess the rural senior primary Natural science teachers' TPACK. This qualitative case study was conducted with senior primary Natural science teachers in the educational circuit of Endola. An interpretive paradigm underpinned the study. The study employed semi-structured questionnaires, semi-structured interviews, focus group interviews, and observation to collect the data. The study used the TPACK as a theoretical and analytical framework. The study results showed that participants had a firmer grasp of subject content (CK) and traditional teaching methods (Pedagogical Knowledge - PK and Pedagogical Content Knowledge - PCK) compared to technological knowledge (TK) and technology-based pedagogies (Technological Pedagogical Knowledge - TPK, Technological Content Knowledge - TCK, and Technological Pedagogical Content Knowledge (TPCK). Findings support that the participants draw upon sources of Technological Pedagogical Content Knowledge (TPACK) closely aligned with Content Knowledge (CK), Technological Content Knowledge (TCK), and Technological Pedagogical Knowledge (TPK) to integrate technology. The study included inadequate professional development, teachers' attitudes, insufficient hardware and internet connectivity, limited technological knowledge, time constraints, and restricted access to technology tools and resources as obstacles for teachers attempting to incorporate technology into their classrooms effectively. Furthermore, the data highlights ICT training and teachers' interest as enablers that motivated participants to integrate technology into their teaching practices. Therefore, the study recommends professional development programs focusing on providing science teachers with practical skills to utilise different technologies and address common technical issues. , Thesis (MEd) -- Faculty of Education, Secondary and Post-School Education, 2024

  • Description: This study sought to assess the management of water services in the Fairview community within the Ixopo town under the Harry Gwala District Municipality (HGDM). The study was further motivated by the need to ascertain stakeholders’ perceptions on the response to water shortage challenges in the Fairview community, assess Fairview community members’ knowledge, and identify opportunities brought about by water shortages in this community. The study was anchored on the service quality model (SERVQUAL) as the theoretical framework. The research design of the study was exploratory and used both qualitative and quantitative methods. The target population of the study consisted of ordinary members of the Fairview community and managerial staff at the HGDM. The qualitative part of the study involved eight (n = 8) managerial employees at the municipality. In total, 120 questionnaires were despatched, and 110 were returned, which gave a 92% response rate for the quantitative part of the study. The questionnaire respondents were chosen by random sampling, while the interview respondents were chosen by purposive sampling. The quantitative data were analysed using descriptive and inferential statistics, while the qualitative data were analysed using applied thematic analysis. The study revealed that there is generally a negative perception of the municipal responses to addressing water supply challenges and that the municipality does not always act promptly to water supply challenges. Perceptions of poor-quality service provision regarding responsiveness, reliability, assurance, and empathy were found. The findings also revealed that the Fairview community members are generally knowledgeable about water conservation. The study unveiled opportunities for addressing water supply challenges, such as mobilising funds from stakeholders to build additional water reticulation, harvesting capacity, and modernisation of water management, and recommends that the municipality immediately conduct public participation meetings and citizen satisfaction surveys to ascertain community service delivery expectations, followed by developing service quality standards and performance agreements with municipal staff to improve residents’ perceptions of the municipality’s ability to respond to water supply challenges. , Thesis (MPA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2024
