- Description: The Albany Thicket Biome has undergone extensive degradation over the past century, particularly from overstocking of livestock in the arid types of thicket. The degradation of the biome, coupled with little to no natural recovery, prompted the South African Government to implement the Subtropical Thicket Restoration Programme (STRP) in the early 2000s to rehabilitate degraded thicket using unrooted Portulacaria afra truncheons. The STRP also sought to create job opportunities, bring about social upliftment, promote biodiversity conservation and incentivise farmers and landowners in the region to promote carbon trading and farming of P. afra using carbon credits. However, the survivorship of P. afra planted using the STRP planting protocol has been less than ⁓30% because they are planted in degraded areas, where the truncheons are subjected to harsh biophysical conditions such as hard, capped soil, high soil temperatures, drought and herbivory. The aim of this study, therefore, was to improve the survivorship of P. afra planted in degraded thicket to at least 30%, using modified planting methods. In this study, four treatments were applied in 210 pondings (or micro-dams), each with P. afra planted in them (the first three treatments used rooted cuttings). The first treatment involved watering regimes where pondings were watered at varying frequencies. The second treatment involved planting companion species alongside P. afra while the third treatment involved planting P. afra underneath a nurse canopy. In the fourth treatment, unrooted P. afra truncheons were planted inside pondings. The mean survivorship of the P. afra cuttings was assessed 18 months after planting. The watering regime treatments, including the control, all yielded a survivorship of over 75%, with the significantly highest levels of survivorship being displayed in the weekly watering treatment (90.9 ± 6.8%) (p < 0.01). The companion plant treatment also produced a high mean survivorship of P. afra (94.9 ± 3.6%), significantly higher than that of the nurse plants (87.5 ± 6.3%) (p < 0.01). Among the unrooted truncheons it was found that untreated truncheons had the highest survivorship (76.2 ± 17.6%), with the lowest mean being found in truncheons that were both pruned and scarified (70.8 ± 20.8%), suggesting that this treatment, out of all of them, is the least successful under the prevailing environmental conditions in the study area. However, there was no significant differences among the unrooted truncheon treatments and their respective survivorship values to further substantiate this assertion (p = 0.26). Findings in this study also suggest that planting P. afra cuttings under a nurse plant was ideal for P. afra survivorship due to the nurse plant’s ability to ameliorate the microclimate under which the cuttings can establish and grow. Despite the soil under the nurse canopy having a significantly lower mean soil water potential (-160.9 ± 200.5 kPa), compared to the open areas (-73.4 ± 55.7 kPa) (p = 0.04), the pondings under the nurse canopy still had a lower mean soil temperature (31.4 ± 5.25°C) than the treatments in the open areas (38.5 ± 2.7°C), during the harsh midday sun. These favourable characteristics are reflected in the P. afra cuttings under a nurse canopy having a higher chlorophyll fluorescence (0.76 ± 0.06). compared to those planted in open areas (0.73 ± 0.13), suggesting that the P. afra cuttings in the former treatment had a higher photosynthetic efficiency compared to those in the latter, despite there being no statistically significant difference in chlorophyll fluorescence between the treatments (p = 0.14). Although these findings suggest that applying these modifications to planting P. afra, having achieved its objective of increasing survivorship to well over 50%, is likely to produce favourable results not only in overall survivorship, but also in fast-tracking arid thicket rehabilitation and restoration, further research on these rehabilitation techniques and their effectiveness is required. Furthermore, the downside to these treatments is that they are costly and time consuming, which puts the feasibility of large-scale programmes using these applications into question. Further investigation is required to determine ways in which the cost-effectiveness of these applications can be enhanced. , Thesis (MSc) -- Faculty of Science, Environmental Science, 2023

- Description: Most informal sector businesses in developing countries participate indirectly in the tax system through paying Value-Added Tax, as well as import and export duties, without being registered as taxpayers. This effectively results in the collection of lower tax revenue than the informal businesses would be liable for if they were registered as taxpayers. Additionally, the nonregistration of informal sector businesses in the tax system perpetuates a culture of non-tax compliance. Countries in sub-Saharan Africa have responded to this challenge by imposing direct taxes on revenue generated in the informal sector. This thesis discussed the informal sector taxation regimes adopted in Tanzania, Ghana and Zimbabwe, with the aim of identifying direct taxes that could be imposed in South Africa on the revenues generated in the informal sector. The goal of the research was to determine the nature of direct taxes that could be imposed in South Africa on the revenues generated in the informal sector, taking lessons from the sub- Saharan countries of Tanzania, Ghana and Zimbabwe. The research was based in the interpretivist paradigm. The data for the research consisted of documentary data dealing with the legislation and experiences of informal sector taxation in South Africa and the countries forming part of this research. The data were analysed using qualitative non-empirical research methods. South Africa has a presumptive tax model in the form of the Turnover Tax system, and it was recommended that this direct tax could be adapted to integrate the informal sector businesses into the tax base. The study made several recommendations to integrate informal sector businesses into the tax base. These recommendations include the implementation of the tax stamp system to tax informal businesses other than minibus taxi businesses, and an income tax sticker specifically designed for the informal minibus taxi industry. , Thesis (MCom) -- Faculty of Commerce, Accounting, 2022

- Description: This study seeks to improve the data analysis process for individuals and small businesses with limited resources by developing a simplified data analysis software tool that allows users to carry out data analysis effectively and efficiently. Design considerations were identified to address limitations common in such environments, these included making the tool easy-to-use, requiring only a basic understanding of the data analysis process, designing the tool in manner that minimises computing resource requirements and user interaction and implementing it using Python which is open-source, effective and efficient in processing data. We develop a prototype simplified data analysis tool as a proof-of-concept. The tool has two components, namely, core elements which provide functionality for the data anal- ysis process including data collection, transformations, analysis and visualizations, and automation and performance enhancements to improve the data analysis process. The automation enhancements consist of the record and playback macro feature while the performance enhancements include multiprocessing and multi-threading abilities. The data analysis software was developed to analyse various alpha-numeric data formats by using a variety of statistical and mathematical techniques. The record and playback macro feature enhances the data analysis process by saving users time and computing resources when analysing large volumes of data or carrying out repetitive data analysis tasks. The feature has two components namely, the record component that is used to record data analysis steps and the playback component used to execute recorded steps. The simplified data analysis tool has parallelization designed and implemented which allows users to carry out two or more analysis tasks at a time, this improves productivity as users can do other tasks while the tool is processing data using recorded steps in the background. The tool was created and subsequently tested using common analysis scenarios applied to network data, log data and stock data. Results show that decision-making requirements such as accurate information, can be satisfied using this analysis tool. Based on the functionality implemented, similar analysis functionality to that provided by Microsoft Excel is available, but in a simplified manner. Moreover, a more sophisticated macro functionality is provided for the execution of repetitive tasks using the recording feature. Overall, the study found that the simplified data analysis tool is functional, usable, scalable, efficient and can carry out multiple analysis tasks simultaneously. , Thesis (MSc) -- Faculty of Science, Computer Science, 2022

- Description: This study considers the experiences of teachers working with Fetal Alcohol Spectrum Disorders (FASD)-affected children in mainstream schooling. FASD refers to a range of conditions in children resulting from maternal alcohol consumption during pregnancy. Prevalence rates in South Africa are said to be among the highest in the world. There is a paucity of research on FASD-affected children in the Eastern Cape. This study was thus conducted in the Buffalo City Metropolitan Municipality (BCMM). Teachers told stories of their experiences of teaching undiagnosed FASD-affected children in mainstream schooling. The stories reveal the quality of life for children in classrooms and socio-contextual influences of their experiences at school, as well as the responsibilisation of teachers in these settings. This qualitative research is situated within a social constructionism paradigm. The social model of disability was utilised as a theoretical framework for this study to represent the systemic barriers against which FASD-affected learner support in the mainstream school can be conceptualised. A sample of five (5) Black female teachers were interviewed. Data gathering was done by conducting telephonic interviews using the single question inducing narrative, known as SQUIN. A thematic analysis of the data was conducted for the purpose of identifying themes within the data collected. Four superordinate themes emerged from the data, viz. narratives of FASD-affected learners, narratives of parental involvement, narratives of the role of teachers and narratives of stakeholder support. This study reveals a significant level of responsibilisation of teachers. Teachers appear to play a bigger role than just being teachers and they positioned themselves as playing a parental role in relation to FASD-affected learners. FASD-affected learners were positioned as “the problem” in the mainstream classroom whereas the environment is a disabling factor to FASD-affected learners. There is a need for a holistic approach in working with FASD-affected learners from all relevant stakeholders. Key recommendations are made for effective inclusion of FASD-affected learners in mainstream schooling. Future research recommendations include repeating this study in a different geographical area, a focus on senior phase learners and/or a more diverse sample. The findings assist in the development of policies of inclusive education in mainstream schooling and supportive strategies to enhance the developmental trajectory of FASD-affected children. , Thesis (MA) -- Faculty of Humanities, Psychology, 2022

- Description: No formal study on the incidence and extent of medullated and coloured fibres has been performed in South Africa. The purpose of this research project was to investigate the validity of the claims that there has been an increase in the production of wool contaminated with medullated and coloured fibres. Therefore, the main aim of this study was to determine whether the incidence and extent of medullated and coloured fibres in the South African wool clip have changed over time. Secondly, the study aimed to determine whether the incidence and extent of medullated and coloured fibres have a distinct geographic distribution. This study explored eight years of wool production records (2010 to 2017) obtained from BKB, the largest wool broker in South Africa. For the purpose of this research, the wool-producing areas of South Africa were divided into 6 regions, according to average annual rainfall, vegetation type and major farming practices applied in the area. Statistical analysis of the data included descriptive statistics, analysis of variance and post-hoc tests, as well as regression analyses. This study succeeded in quantifying the extent and prevalence of contamination with medullated and coloured fibres in the South African wool clip. The overarching conclusions were: • Floating kemp is the most important contaminant of wool in South Africa, with the incidence of harsh kemp and coloured fibres being very low. • Generally, the most important areas that need attention in combatting contamination in the South African wool clip, are the Mixed Farming Summer Rainfall Region, the Semi-Arid Grassveld and the High Rainfall Grassland. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: This treatise aimed to critically analyse a taxpayer’s rights relating to a request by SARS for relevant material, in respect of an audit (including information requested for the audit of prescribed tax periods). The study also considers whether such a request for relevant material infringes or threatens a taxpayer’s constitutional rights to privacy, information and just administrative action that is lawful, reasonable and procedurally fair. The research considered the information-gathering powers awarded to SARS in terms sections 3(2), 40 and 46 of the TAA versus a taxpayer’s rights to privacy, information and just administrative action in terms of the Constitution. The reasonable and justifiable limitation of taxpayers’ rights, in terms of the general limitation clause contained in section 36(1) of the Constitution, was also considered. The research method consisted of a literature review of various articles, journals, publications, books, statutes and related commentary, judicial decisions and comments of experts. The study revealed the following: • The definition of ‘relevant material’ allows SARS alone to subjectively determine what information is ‘foreseeably relevant’ for the ‘administration of a tax Act’, in respect of an audit. The threshold of what documentation is ‘foreseeably relevant’, is low, and the application of what is foreseeably relevant follows very broad grounds. • SARS’s discretion cannot be easily challenged as the provisions of section 46 of the TAA are peremptory and give rise to mandatory obligations, unless the taxpayer has ‘just cause’ for not providing the relevant material to SARS. • SARS must meet all the jurisdictional requirements of section 3(2) of the TAA to justify that the selection of a taxpayer for an audit or the request for relevant material is necessary for the purposes of the ‘administration of a tax Act’ and is not related to a ‘fishing expedition’ or some other ‘ulterior purpose’. • A taxpayer should evaluate the scope of the information requested to determine if it is ‘frivolous, over-zealous or patently irrelevant’ and falls outside the provisions of section 3(2). It is submitted that a taxpayer could resist such requests to information, to which SARS is not lawfully entitled, to ensure that its constitutional rights are not violated. • A taxpayer is not entitled to the information that SARS used to select it for an audit or SARS’s internal guidelines or policy manuals that are used by its assessors. The risk x indicators and red flags used by SARS to select a taxpayer for an audit constitute ‘SARS confidential information’ and a taxpayer does not have any legal right to specific reasons as to why his tax return has been selected for an audit. • SARS’s decision to request relevant material (or to conduct an audit) is a preliminary or initial step of a process and does not constitute ‘administrative action’ in terms of the PAJA, as it does not adversely affect a taxpayer’s rights nor have a direct external legal effect. A taxpayer therefore cannot rely on the PAJA to refuse such a request. • Even non-administrative action is subject to the broad constitutional ‘principle of legality’, which is an aspect of the rule of law implicit in the Constitution and provides a safety net when the PAJA does not apply. SARS must act within the scope of section 46 and the information requested must constitute ‘relevant material’ and must be ‘foreseeably relevant’ for the purposes of ‘administration of a tax Act’. SARS may not exercise its discretionary investigative powers in an arbitrary or irrational manner and its requests for information must be based on sound, rational decision-making. , Thesis (MA) -- Faculty of Business and Economic science, 2022

- Description: The volume of information generated lately has led to information overload, which has impacted researchers’ decision-making capabilities. Researchers have access to a variety of digital libraries to retrieve information. Digital libraries often offer access to a number of journal articles and books. Although digital libraries have search mechanisms it still takes much time to find related research papers. The main aim of this study was to develop a model that uses machine learning techniques to recommend related research papers. The conceptual model was informed by literature on recommender systems in other domains. Furthermore, a literature survey on machine learning techniques helped to identify candidate techniques that could be used. The model comprises four phases. These phases are completed twice, the first time for learning from the data and the second time when a recommendation is sought. The four phases are: (1) identify and remove stopwords, (2) stemming the data, (3) identify the topics for the model, and (4) measuring similarity between documents. The model is implemented and demonstrated using a prototype to recommend research papers using a natural language processing approach. The prototype underwent three iterations. The first iteration focused on understanding the problem domain by exploring how recommender systems and related techniques work. The second iteration focused on pre-processing techniques, topic modeling and similarity measures of two probability distributions. The third iteration focused on refining the prototype, and documenting the lessons learned throughout the process. Practical lessons were learned while finalising the model and constructing the prototype. These practical lessons should help to identify opportunities for future research. , Thesis (MA) -- Faculty of Engineering, the Built Environment, and Technology, 2022

- Description: Micro contractors (MCs) in construction are pivotal to the growth of the South African economy. The South African construction industry has world-class H&S legislation and regulation; however, frequent accidents occur at an alarmingly high level. Accident statistics presented in this thesis paint a worrying picture of a vicious cycle of recurrent accidents and injuries in the South African construction industry. Whilst governments planned National Development Programme will provide opportunities for MCs, in hindsight there’s dire need to have solid foundation of H&S development prior to MCs expanding operations into small and medium sized enterprises. The grouping of very small contractors into MCs under the definition of Schedule 1 of the National Small Business Act (NSBA) may result in fewer Health & Safety (H&S) initiatives aimed at the MCs, given the turnover limit has a maximum of R10 million per annum. The topic incorporated ’reasonably practicable’, to identify what MCs currently know, and ought to know, about the hazards or risks on construction sites, and then develop a pragmatic framework to eliminate or minimise risk. MCs generally did not understand H&S regulations hence carried out tasks for the sake of compliance. Punitive measures and enforcement of H&S regulations have done little to reduce the number of accidents. The study provided context for management and employees at MCs to approach H&S in a logical approach without circumventing H&S regulations. The challenges affecting MCs determined that there’s need for specialised H&S legislation and regulation to be developed for MCs that factors socio-economic challenges of literacy, skills, affordability, and poverty. Consequently, structured methods of support by stakeholders in the form of support and mentorship would result in a significant improvement of MCs’ H&S performance. Standards such as the ISO 45001:2018 state that it can be implemented for all size of construction firms. Whilst this standard may be suitable for MCs in developed countries there exists a vacuum in terms of its applicability to MCs in South Africa. The main objective was to develop a framework for MCs that will help to reduce accidents while simultaneously improving sustainability and service delivery. ii The research adopted an interpretivism philosophical position, which is reliant on people's views and conduct. The research applied deductive reasoning by survey technique and to construct a theory of H&S issues and corrective measures through research questions. The study adopted a mixed method research approach using a survey sent to the members of the South African Institute of Occupational Safety and Health (Saiosh), persons registered with the South African South African Council for the Project and Construction Management Professions (SACPCMP), and members of the Association of Construction Health and Safety Management (ACHSAM), and using the thematic analysis of data from 16 interviews representatives of member organisations, H&S consultants, and PCs. Accident statistics obtained from the Federated Employers Mutual Assurance (FEM) were also analysed. The study findings indicate that a reasonably practicable H&S programme must be developed for MCs due to the ‘onerous’ requirements arising from the Occupational Health and Safety Act (OHS Act) and Construction Regulations (CR). The study determined that it would be unaffordable for MCs to implement and maintain the ISO 45001:2018 standard. H&S practices at MCs under guidance of a H&S practitioner can be deemed to be undertaken frequently, as opposed to infrequently, however, new entrant MCs struggled to comply with H&S legislation and regulations and that has resulted in a H&S culture being generally non-existent or difficult to establish. The significance of this study lies in the recommendations that are proposed. Effective H&S in MCs require greater support from the Department of Employment and Labour (DEL), member organisations and the PCs in construction. The study proposes that a national H&S logbook be set up to record H&S compliance and accidents at MCs. Furthermore, a phased approach should be instituted for improving H&S. These phases should include phase one, for new entrant MCs from zero to three years, phase two for MCs during the development and growth phase from three to five years, and MCs deemed competent with H&S should be encouraged or required to train and mentor new entrant MCs. , Thesis (MA) -- Faculty of Engineering, the Built Environment, and Technology, 2022

- Description: The fast-moving consumer goods (FMCG) sector contributes significantly to the gross domestic product (GDP) growth of the country. It is however regarded as one of the unpredictable sectors due to rapid technological advancements, new regulations, and intense competition. This has therefore led to the growth in importance of reverse logistics (RL) since the FMCG sector cannot avoid RL. This is because FMCG can be damaged in transit, recalled, returned due to unsatisfied customers, defects, or scrap material, amongst others. It is therefore important for the sector to implement RL practices and strategies that can lead to the firm’s competitiveness. This will further assist in recapturing the value of the products. Recently, RL has gained a lot of attention in both research and in practice. Nevertheless, not so much research has been done in the FMCG sector in SA. Through the implementation of RL practices, strategies and an effective RL management system, this sector will achieve many goals as well as lead to the firm’s competitiveness. The current study mainly sought to develop an RL competitiveness framework to help guide FMCG retailers. The study also investigated the RL practices, best practices, critical success factors (CSFs), strategies and their influence on the firm’s competitiveness. A positivist research philosophy, which combined descriptive and explanatory research was employed. Data was collected through two close-ended questionnaires, via SurveyMonkey, from 418 FMCG retailers and consumers. The descriptive results from the Statistical package for the Social Sciences (SPSS) version 27 showed that FMCG retailers to a great extent implement the recalling of products. The results also revealed that FMCG retailers have centralised returns centres, and they share information and collaborate with suppliers for effective remanufacturing of products that have reached their end of shelf life, as highly implemented RL best practice, amongst others. Little understanding of the importance of RL, high costs associated with adopting RL practices, lack of top management support on RL initiatives, high cost of RL technology and customers’ unwillingness to pay extra for any RL practices and initiatives were identified as the key RL challenges faced by FMCG retailers. The descriptive results further cited financial resources, employment of skilled personnel to handle RL, having knowledge on RL and technology as the extremely critical factors in the successful v implementation of RL among FMCG retailers. The following RL strategies were identified as the highly implemented among FMCG retailers: integration of forward logistics (FL) and RL, the implementation of new technology, the adherence to environmental policies and regulations, knowledge management, eco-compatibility, and strategic alliances The structural equation modelling (SEM) analysis conducted using AMOS version 27, revealed that RL practices have a positive and significant influence on RL strategies. The results also revealed that RL strategies have a positive and significant influence on the firm’s competitiveness. The mediation results revealed that RL strategies fully mediate the relationship between the firm’s competitiveness and RL practices. Based on the empirical results and reviewed literature, a conceptual model and an RL competitiveness framework were developed and suggested. Moreover, the study recommended that the managers increase customer awareness of RL practices implemented by FMCG retail firms, train and educate their personnel on RL, enhance RL strategies to improve RL practices implementation success, and enforce RL formal policies. This study significantly contributes towards the development of future studies in RL and firm competitiveness through new insight and contribution to the body of knowledge. , Thesis (PhD) -- Faculty of Business and Economic science, 2022

- Description: he total size of the South African Business Process Outsourcing sector is not growing as quickly as other global BPO locations like the Philippines and India. The sector has been identified by the South African government as a key sector for economic growth and for reducing unemployment. Reviewed frameworks are not exhaustive in providing a framework that is suitable for countries with an apartheid history like South Africa, so, the main aim of this study has been, therefore, to develop a structural model for sustainable growth of the South African BPO sector. The research was two phased: Firstly, it interrogated existing theories and models on BPO growth to identify variables for BPO growth. The variables were identified as talent pool, infrastructure, accessibility, lower costs, and legislative framework. The relationships between variables were hypothesised. The reviewed literature discussed the global economy and traced the origins of outsourcing as rooted in the advent of Information Technology and computer-enabled production which enabled fragmented processes which could be in any part of the world. The literature showed that competition for markets, coupled with a glut of products on the market, forced creativity which resulted in companies seeking operations in low-cost locations. The first popular locations for BPO operations were India and the Philippines, with emerging locations, like South Africa, positioning themselves to tap into this global development. Secondly, a quantitative study was performed using a web-based questionnaire which was sent to a sample of BPO executives in the BPO value chain in South Africa to test relationships among between variables. The results of the study showed statistically significant relationships between talent pool, infrastructure, lower costs, accessibility and legislative framework with BPO growth, albeit with varying degrees of strength. Contrary to popular belief, lower costs are no longer the most important driver of BPO location choice. Accessibility and legislative framework have also been confirmed by data as variables affecting BPO growth. After the computation of the relationships, the research concluded that the model developed is a good fit for BPO growth. , Thesis (PhD) -- Faculty of Engineering, the Built Environment, and Technology, 2022

- Description: A survey of food safety practices and microbial risk related to ready-to-eat chicken in food outlets from a university campus in South Africa was investigated. The objective of the study was to determine the food safety practices and hygiene knowledge of food handlers in food outlets at a South African university campus. Six food outlets out of the thirteen university food outlets that were similar in type were selected for the study. These six food outlets were selected based on establish criteria but did not comply with HACCP principles. To assess the possible contamination risk related to hygiene practices and processing of ready-to-eat chicken, Total Viable Count, Escherichia coli, Salmonella and Staphylococcus aureus counts were determined using standard methods. A validated questionnaire was used to assess the educational levels of each of the 27 participating food handlers; as well as the determination of the food handlers’ personal and general hygiene. Microbial levels of each food handler hand, aprons, as well as the microbial contamination levels of direct food contact surfaces, and ready-to-eat chicken at each facility were evaluated using standard methods. Several risky non-conforming personal and general hygiene practices were detected during the study. Appropriate corrective actions such as an intensive food hygiene training programme accompanied by a food management system should be implemented in all food facilities. , Thesis (MA) -- Faculty of Health Sciences, 2022

- Description: The study sought to explore the nature and extent to which community participation takes place for sustainable rural development at Malamule village, to better understand how to accelerate participation at both a regional and local level leading to sustainable development. The study further investigated how community members participate and involve themselves in sustainable rural development processes and at the same time, it identified approaches used to encourage community participation and sustainability of rural development. A qualitative research methodology was adopted where semi-structured telephone interviews were conducted with community members and project managers from two NGOs in Malamule village. A thematic analysis was adopted in this study as it drew on a few thoughts introduced from the hypothetical framework supporting this investigation. There were four main findings of the study: 1) that community members of Malamule consider participation as a tool of emancipation and that they are not just development beneficiaries but influencers; 2) that the existence of NGOs brings about significant relief to the community of Malamule, while too much dependency on them could cause long term problems if the community does not learn to be self-sufficient; 3) that only a small amount of resources, or support, is needed to set up something sustainable; and 4) that the community of Malamule is undergoing many challenges, which results in class disputes that eventually translate into lack of unity. The following is recommended: that NGOs prioritise full involvement of the target communities to promote participation; that NGOs must continue to create awareness in Malamule through consistently training and equipping community members; and that there is a need for the community members and NGOs to continue working together so that sustainable development can be achieved. , Thesis (MA) -- Faculty of Business and Economic Sciences, 2022

- Description: The South African Information Technology (IT) sector is experiencing a chronic skills shortage, and the skills gap is widening. South African organisations try to retain existing skilled IT professionals in order to compete on a global platform, whilst simultaneously competing against international organisations who poach IT professionals from South Africa in what is referred to as “brain drain”. The South African IT sector is an increasingly important contributor to South Africa’s GDP, with several international corporates investing and creating opportunities in South Arica, including IBM, Dell, Microsoft and Intel. The retention of skilled IT professionals in South Africa is complex and costly due to the high demand for these professionals. An overview of the literature was provided that commenced with a broad analysis of strategic talent management frameworks in order to present a holistic view of talent management. From this broad analysis, the literature review narrowed the focus to the retention of talent. This section focused on the impact of organisational culture and employee engagement, whilst considering the critical roles that managers and leaders play in culture and employee engagement pertinent to the South African IT sector. The research paradigm adopted for this research was interpretivist and the methodology was qualitative research. The empirical data was collected through conducting semi-structured interviews with six IT professionals with extensive experience in the sector, and who directly play a role in the management and retention of skilled IT professionals. Various themes were developed from the interviews, with a focus on the extent of the skills gap and considerations regarding organisational culture, employee engagement and expectations from leaders and managers detailed in the themes. Finally, a talent retention framework for the South African IT sector was developed from the emerging themes. The themes included culture and the work environment, remuneration and benefits, continuous growth and employee engagement. , Thesis (MA) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: Climate change is widely acknowledged as one of humanity's most pressing problems in the twenty-first century. The emission of greenhouse gases (GHGs) has changed the earth's normal climate cycle by raising the earth's surface temperature. The severity and frequency of various natural catastrophes, such as storms, floods, heat waves, and droughts, have increased as the earth's surface temperature has risen. These events have a devastating effect on populated areas; contaminating clean drinking water, leading to uncontrollable wildfires, damaging properties and infrastructure, environmental pollution, and loss of life. The increase in GHG emissions is largely contributed to by the built environment and the human activities within these areas. This research aimed to investigate the current state of climate change and the impact on the built environment. Furthermore, a quantitative approach was taken with regards to the research and a descriptive survey was conducted among professionals that work within the built environment, namely architects, project managers, construction managers, and electrical and mechanical engineers. The salient findings are: very few participants actively participate in activities to enhance their knowledge of climate change; most participants have a good understanding of what climate change is, although they make no extra effort to implement mitigating strategies on their projects other than what is required by the local council; most participants are unsure with respect to the impact that climate change has on the built environment, and most participants are unaware of global initiatives that South Africa has contributed to, to reduce GHG emissions. Governments and organisations around the world have implemented rules and regulations to regulate and decrease GHGs in the atmosphere, but it is still increasing at an accelerated rate. The increase of GHG emissions is devastating on all sectors of the built environment and will only intensify over time. As advancements are made to reduce GHG emissions progress has also been made to adapt to an ever-changing climate, specifically in the construction industry. Architecture and building processes have evolved to not only reduce the harmful effects on the environment but also to be more efficient and sustainable. , Thesis (MA) -- Faculty of Engineering, the Built Environment, and Technology, 2022

- Description: The South African higher education geography is one that is met with contesting ideas. The establishment of the university in Africa was a project to mimic the exclusionary nature of the western university. Of centering a particular knowledge and way of being, leaving African women and other marginalised groups outside of the culture of the space and away from the possibility of being knowledge producers. The end of Apartheid, signaled an opportunity for new policies that address racial, gendered and various other lines of oppression and marginalisation. Universities, Technical and Vocational Education and Training (TVET) colleges with different histories were merged to make way for the new South Africa. Access to institutions of higher education opened up across geographies, making way for a multicultural student and staff demographic. This transformation has also led to the transformation of the leadership structures of such spaces, with currently only five institutions being led by female and women, out of twenty-six in the country. The aim of this study is to understand the experiences of African women who are leaders in universities, focusing on how they negotiate a history of being excluded in the space with the present context of being able to influence the future of higher education. Using an African feminist lens, I draw on five individual interviews and secondary data from previous studies to excavate phenomenological experiences. The findings reveal that feminist traits of equality of social justice are integral in how the participants perform their leadership. The findings also show experiences of belonging in the culture of the university cause a great deal of tension of which the leaders are constantly working to change, to establish different cultures of being and existing in the South African university. , Thesis (MA) -- Faculty of Humanities, School of governmental science and social sciences, 2022

- Description: The study examined performance management and organizational success in local government administration in South Africa with a focus on Buffalo City Metropolitan Municipality (BCMM), Eastern Cape Province. It adopted the mixed method approach, namely, qualitative, and quantitative research methods. In-depth face-to-face interviews were conducted with a sample of 20 participants from Buffalo City Metropolitan Municipality (BCMM) who were selected using the purposive sampling technique. The study also distributed 100 questionnaires to BCMM employees who were selected using random sampling technique. The target population of the study was the employees of BCMM. Based on the analysis of data, the study found that the municipality did not have an electronic system; they were using a manual system in their performance management. Further to this, the respondents also highlighted that there was no approved Performance Management System (PMS) policy framework that had been endorsed by the council of the municipality. From this conclusion, the study recommended that the municipality must have an approved PMS policy framework and it should be implemented at all levels of employment within the organization. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2022

- Description: This research study investigated the Motherwell Township community members regarding academic drop out. The Motherwell Township is located in the city of Port Elizabeth and it is one of the largest townships in South Africa. The current outlook of South Africa’s education system has many challenges which is greatly impacted by poverty, insufficient resources and inequalities in terms of schooling, race and class. South Africa is one of the many countries with a high number of students who do not complete their university studies. This influences the young people’s future as it reduces the chances of employment. To understand the factors that contribute to academic drop out, this research study explored factors that causes female and male students to drop out. The community members provided the following reasons; lack of financial stability to sustain their academic tuition, poor performance, peer pressure, consumption of harmful substances such as alcohol and drugs, pregnancy, rape and illnesses. These factors suggested three underlying themes that influence students to remain in school namely, improvement of health facilities, better financial policies e.g. university scholarships and reduction of poverty. The objectives of this study are as follows: to investigate the causes of academic drop outs in Motherwell Township, to contribute with the anthropology of education particularly with reference to Motherwell Township in the Eastern Cape Province and to come up with recommendations with the view to address some of the challenges faced by the people who are affected. , Thesis (MA) -- Faculty of Humanities, Sociology and Anthropology, 2022

- Description: This study investigated the impact in the telecommunication and broadband sectors on growth, employment creation, and poverty alleviation. It employs micro-simulation techniques and an economy-wide Leontief-based social accounting matric multiplier model to assess empirically the influence that fiscal injection into these sectors has in achieving South Africa's macroeconomic objectives. The study found positive but declining trends in output multipliers in the telecommunication sector over the past recession period (2009-18), signifying the enervation of the intersectoral multiplier effect over the post-recession period. Fiscal injection into the telecommunication and broadband sectors led to poverty reduction and to job creation in South Africa. However, the overall findings of this study highlight gender biases, spatial imbalances between urban and non-urban, an age gulf between young people and adults and further imbalance between formal and informal employment. The study commends that the government follows a priorities- weighted state spending policy which concurrently targets projects generating high gross value added and employment multipliers and with high capacity to address the disparity caused by the legacy of aparthied , Thesis (MA) -- Faculty of Business and Economic science, 2022
