- Description: This research study explores indigenous sorghum food management practices as a pathway towards sustainable food systems. The level of hunger is ever-increasing, and so is the global population. Regions less industrialized and developed suffer the most as they host growing populations and most of the worlds undernourished. Further intensified in this problem are a culling and unforgiving food systems run by a few conglomerates and a knowledge system driven by a histography of ‘othering’ even in its knowledge creation process. Although there exist institutions such as the United Nations Food and Agricultural programs, these remain relegated to policy and intergovernmental level, in the process, not being mindful of the real food issues faced at the grassroots level. This research study centralizes indigenous food practices to make sense of how rural and indigenous livelihoods such as those located in the Moshana village thrive and survive in a monopolized and urban-centred food climate like South Africa. By interviewing 12 participants, living, and taking part in the Moshana village food systems and employing stringent face-to-face semi-structured interviews, we present an indigenous food system as experienced and shared by Moshana Village Community members. The findings present an array of indigenous and food management practices, perspectives through an African ecological philosophical view. Conceptually inspired by the works of Vandana Shiva and many global south thinkers on seeds, grains and sustainable indigenous food systems, this study hopes to reinsert back the centrality of food in the growing field of African Sociology. The findings clearly show that elderly women are preserving the Sorghum knowledge and preservation processes. These practices have assisted the Moshana Village community members to cope with food shortages and lockdown restrictions during the strict COVID-19 lockdown in South Africa. The study concludes with clear need for the archiving and intergenerational communication of food management within the rural communities. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2022

- Description: This study was concerned with exploring and describing a solution to optimise access to development finance for SMMEs in South Africa. SMMEs and entrepreneurs have long been identified as key drivers of economic development, job creation, and poverty elevation. In response to this and, in an effort to support SMMEs, the South African Government has established a number of development finance institutions with a specific mandate to support SMMEs by providing them with both financial and non-financial support. However, this much-needed support is constrained by several independent factors. The objective of the study was to identify information technologies that are currently available in the financial sector and explore how they can be integrated into development finance institutions (DFIs) and SMMEs to streamline their access to finance. The research started with a structured literature review, followed by a qualitative case study research design, and utilised ten (10) embedded units of analysis. These respondents consisted of industry experts in the field of SMME finance, senior employees within the sampled developmental finance institutions, as well as experts in the financial technology sector. The findings of the study, through the views of the sampled industry experts and relevant literature reviewed, revealed that it can be collectively summarised that there is a need for information technology such as Fintech in the development finance and SMME sector in South Africa. It is evident that a need exists to streamline the current application process to access development finance for SMMEs looking for finance. There is a significant misalignment between the current demand for development finance by SMMEs and the magnitude of finance supplied by DFIs to SMMEs looking for finance. The study then concluded with practical recommendations for the streamlining of development finance by using relevant Fin tech solutions. , Thesis (MBA) -- Faculty of Business and Economic Science, 2022

- Description: Caring behaviour, which is defined as nurturing another to whom one feels a personal sense of commitment and responsibility, is fundamental to the psychosocial component of midwifery. Midwives ought to show respect, kindness and continuous psychosocial support during childbirth to women, who have the right to receive the highest possible standard of care and to be treated with dignity and respect before, during and after childbirth. However, an increasing number of complaints of the uncaring behaviour of midwives towards labouring women has indicated a problem that has not been fully researched. Therefore, the study aimed to identify and describe caring behaviours in the context of midwives in Botswana; determine the inhibiting factors of caring behaviours of midwives during childbirth; and make recommendations to midwives and unit managers based on Swanson’s (1991) Theory of Caring, which might lead to the optimisation of caring behaviour in Botswana midwives. A quantitative, descriptive research design was followed to answer the research questions, and a structured, self-administered questionnaire, which had been developed by the researcher based on the literature review, was used to capture data. A purposive sampling method was used to select 200 respondents working in maternity units in the Kgatleng and Greater Gaborone regional health districts in Botswana. The questionnaire was evaluated for reliability and validity to ensure that it consistently and accurately measured what it was intended to measure. A pilot study was conducted with 10 midwives who met the criteria for participation in the study to pre-test the feasibility of the questionnaire in preparation for the main study. In addition, ethical principles, such as informed consent, respect for persons, anonymity, confidentiality and beneficence were followed throughout the study. The questionnaire consisted of questions and statements. It was divided into three sections. Section A: Demographic attributes; Section B: Identification and description of the caring behaviour of midwives: Section C: Determination of the inhibiting factors of caring behaviours in midwifery. The data provided by the respondent’s answers to the questionnaires were statistically analysed using the Statistical Package for Social Science (SPSS®): Version 27 with the assistance of a statistician, thereby generating descriptive and inferential statistics. v The results of the data analysis revealed that most of the respondents provided positive responses, thereby indicating caring behaviour in midwifery practice. However, several factors that inhibit the caring behaviour of midwives were identified, such as a shortage of staff, work overload, a poor working environment, the inconsistent selection of staff for professional development, a lack of equipment, the young age of some of the woman (less than 15 years), the parity of the woman (more than one child) and the negative behaviour of many of the women. Therefore, recommendations for midwives and unit managers based on the five processes of Swanson’s (1991) Theory of Caring were made that could be used to optimise midwifery care in Botswana. , Thesis (MNurs)-- Faculty of Faculty of Health Sciences, 2022

- Description: The perceptions of causes of depression are diverse, formulated from many different factors such as personal experiences, education, generational and cultural influences, and religious beliefs. While there is a large body of literature on both depression and religion and culture, there is a limited amount available that synthesizes the findings of multiple different studies, finding key common themes. Therefore, this review aimed to develop a comprehensive understanding of how religious and cultural narratives describe and influence depression. As a result, a meta-ethnography was carried out to synthesise existing literature on cultural-religious narratives of depression within a South African context. Five published journal articles were sampled for translation and synthesis. From this process, three key themes were developed, namely Conflictual Coexistence, Observation-Based Discernment, and Status or Stigma. The result is a lens that is formed through a mixture of traditional cultural religious traditions and beliefs interconnected with contemporary ways of understanding and being. This framework for diagnosing and treating a mental illness is heavily reliant on observable symptoms. As a result, status or stigma can be attached to multiple aspects of the situation surrounding an individual with or suspected of having a mental illness. Stigmatisation can be noted to form a cycle that becomes inclusive of prognosis, finance/employment and not being able to fulfil culturally held expectations. As a result, future research, and therapeutic intervention of this mental disorder within this demographic will be better informed. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2022

- Description: This study investigated the impact of investment 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 matrix 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 post-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 imbalances between formal and informal employment. The study commends that the government follow a priorities-weighted state spending policy which concurrently targets projects generating high GVA and employment multipliers and with high capacity to address the disparity caused by the legacy of Apartheid. , Thesis (MEcon) -- Faculty of Business and Economic Science, School of Applied Accounting, 2022

- Description: This research aims to determine how the principle of anticipatory self-defence, in line with article 51 of the UN Charter, can be applied to the context of maritime cybersecurity. Despite the debates by some scholars to clarify the international law position on anticipatory self-defence in the maritime context, there is no universally accepted legal provision for States to rely on in carrying out anticipatory self-defence against imminent maritime cyber-attacks. This raises the questions concerning the lawful steps States can take in self-defence against maritime cyber-attacks. This research shows the challenges facing States in their bid to comply with the provision of article 51 of the UN Charter to anticipatorily defend against an MCA. The recommendations made are intended to guide States in making policies and mapping our strategies to lawfully tackle the emerging threat of cyber-attacks against maritime security. , Thesis (LLD) -- Faculty of Law, School of Environmental Sciences, 2022

- Description: The therapeutic relationship established between a psychologist and a client is considered one of the main factors determining successful psychotherapy outcomes. While this may be the case, there remain inconsistencies in the literature and debate regarding its influence, especially when contextual factors such as diverse beliefs, may influence the therapeutic relationship. Furthermore, there is a scarcity of information focusing on psychologists’ experiences working within the culturally diverse South African context. This study aimed to better understand, from a psychologist’s perspective, the growth and change promoting factors they feel are influencing successful therapeutic outcomes within the South African context. This was pursued recognising that the diverse belief systems in South Africa, which do not always adhere to biomedical conceptualisations of health and illness, may influence the therapeutic interaction. This study explored the following research question: What are the key factors that promote growth and change in individual psychotherapy within the diverse South African context? Drawing on a qualitative approach, an explorative descriptive research design was chosen as it enabled the researcher to explore the perceptions of the participants on the given topic. The sampling technique that was employed was non-probability purposive sampling and psychologists registered with the Health Professionals Council of South Africa formed part of the sample. In-depth online interviewing was employed as the data collection tool, using online platforms like Microsoft Teams and Zoom. Data were analysed using Braun and Clarke’s thematic analysis guidelines and themes that were identified was reported. , Thesis (MA) -- Faculty of Health Sciences, 2022

- Description: The purpose of this study was to investigate the factors that affect understanding of business strategy at different levels of the organisation. The investigation was done by looking at relationship between the business strategy (as a dependant variable) and the organisational structure, the employee level or position, skills, experience and education (as independent variables). These factors were investigated through the analysis of literature and empirical study. The results of this analysis were recorded through the last two chapters (chapter four and five). As in most organisations, there is sometimes different interpretations of business strategy by employees at different levels (or sometimes across) of the organisational structure. This study does not just seek to add value in the literature but also to equip managers tasked with enrolling out business strategies. The basis of the study emanates from corporate failures associated with the business strategies and the failure of implementation and this is discussed further in chapter one with reference to specific sources. The empirical study that was conducted attracted a good response, as there was more than 100 percent response rate, through the use of latest technology and social media. The main conclusions, managerial implications and theoretical framework that came through from the study, are clearly stated in the last chapter, chapter five and can help managers that formulate or implement to business strategies, to ensure that there is great understanding within their workplaces. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2022

- Description: The desperate need for South Africa to develop its oil industry is driven by the goal of improving the social and economic situation in the State. This goal has sparked an interest in expanding the exploration and exploitation of oil within the marine environment to the extent of venturing into uncharted deeper waters.1 This interest has been met with a constant reminder of the Deepwater Horizon explosion as one of the many events that stirred up concerns within the global community on the possibility of an oil spill causing pollution within the marine environment. Also, that explosion and its effects have demonstrated the need for the global community to closely monitor and effectively regulate environmental matters, including the exploration and exploitation of oil and the prevention of oil pollution.2 Therefore, the recent discovery of additional oil deposits in South Africa has confirmed the need to revisit the current legal system regulating the impact on the marine environment including the exploration and exploitation of oil.3 An oil spill causing pollution amongst other pollutants is a significant contributor to loss and damage to the marine environment and its habitat. In developing States like South Africa, an oil spill causing pollution can present challenges due to the scarcity of resources, technology, and knowledge to prepare, prevent and combat the spreading of the pollutant. As it stands, in the event of an oil spill, States must rely on international cooperation and expertise to ensure that the impact does not cause irreversible harm and degradation to the marine environment. South Africa within the global community gives effect to international law by adopting domestic laws that regulate the exploration and exploitation of oil to protect the environment from oil spills causing oil pollution within the marine environment. In addition, the liability caused by oil spills plays a vital role in the need to rehabilitate the marine environment and compensate the aggrieved parties. , Thesis (LLM) -- Faculty of Law, Department of Public law , 2022

- Description: The desperate need for South Africa to develop its oil industry is driven by the goal of improving the social and economic situation in the State. This goal has sparked an interest in expanding the exploration and exploitation of oil within the marine environment to the extent of venturing into uncharted deeper waters.1 This interest has been met with a constant reminder of the Deepwater Horizon explosion as one of the many events that stirred up concerns within the global community on the possibility of an oil spill causing pollution within the marine environment. Also, that explosion and its effects have demonstrated the need for the global community to closely monitor and effectively regulate environmental matters, including the exploration and exploitation of oil and the prevention of oil pollution.2 Therefore, the recent discovery of additional oil deposits in South Africa has confirmed the need to revisit the current legal system regulating the impact on the marine environment including the exploration and exploitation of oil.3 An oil spill causing pollution amongst other pollutants is a significant contributor to loss and damage to the marine environment and its habitat. In developing States like South Africa, an oil spill causing pollution can present challenges due to the scarcity of resources, technology, and knowledge to prepare, prevent and combat the spreading of the pollutant. As it stands, in the event of an oil spill, States must rely on international cooperation and expertise to ensure that the impact does not cause irreversible harm and degradation to the marine environment. South Africa within the global community gives effect to international law by adopting domestic laws that regulate the exploration and exploitation of oil to protect the environment from oil spills causing oil pollution within the marine environment. In addition, the liability caused by oil spills plays a vital role in the need to rehabilitate the marine environment and compensate the aggrieved parties. , Thesis (LLM) -- Faculty of Law, Department of Public law , 2022

- Description: The environmental challenge posed by waste tyres is a serious global crisis from which South Africa is not isolated. The concept of tyre rubber reclamation into reusable rubber over the years has been on the increase, however, despite the environmental and economic advantages offered by the reclaiming process the main demerits of the resulting rubber include its relatively poor physical and mechanical properties when compared to newly manufactured rubber. The deterioration of these properties arises from the structural changes which occur during the reclaiming process. To overcome this disadvantage, reclaimed rubber can be blended with other rubbers such as natural rubber to compensate for its weak properties. However, there is stilll a limited industrial application of reclaimed/natural rubber blends due to their brittleness and relatively poor impact strength. By adding reinforcing fillers, the mechanical properties of the blends can be significantly improved. In recent years, there has been a renewed interest in the use of lignocellulosic materials as fillers, modifiers and reinforcements in polymeric materials. They are receiving attention because they are the most abundantly available raw materials on earth, and they offer greater versatility compared to inorganic fillers. Being the most abundant renewable agricultural derived lignocellulosic biomass after cellulose, and as far as polymer composites and blends are concerned, lignin has shown promise as a well-received and sustainable alternative to inorganic fillers due to its low-cost production and ability to improve on the biodegradability of polyolefins and minimise loss of ultimate mechanical properties of polymer matrices. The main aim of the research is to investigate the effect of lignin on the properties of reclaimed/natural rubber (RR/NR) blends for possible low-density and eco-friendly rubber materials. The motivation for the research arises from the global challenges that are connected to the dynamic increase of rubber wastes, especially in the form of used tyres and the potential availability of lignin from its annual production from the sugarcane pulp mills, which is regarded as waste. A mixture design of experiments was used to formulate different blends of lignin with reclaimed and natural rubber.

- Description: Background: Aminoglycosides are highly effective against Gram-negative bacteria, including ESKAPE pathogens. However, aminoglycosides can cause nephrotoxicity and ototoxicity. Therapeutic drug monitoring (TDM) performed in patients receiving aminoglycosides can potentially reduce the development of antimicrobial resistance as well as aminoglycoside-induced toxicity and side effects. Primary Aim: The study aimed to identify TDM practices and subsequently develop a model for aminoglycoside TDM at a private hospital in the Eastern Cape. Methodology: Phase One involved the collection of data from the hospital’s database, using a purpose-designed data collection tool. Data from 135 eligible patients who received aminoglycoside therapy from June 2019 to June 2020 were reviewed. Data was captured, coded and analysed (using differential analysis). Semi-structured interviews were conducted (Phase Two) with three physicians and five pharmacists. Interview transcripts were coded using a combination of inductive and deductive coding techniques, followed by thematic analysis. The data was triangulated and used, together with recommendations from similar guidelines, to design a context-specific model for aminoglycoside TDM at the hospital. Results and Discussion: Results from Phases One and Two showed that TDM was not being performed correctly at the hospital. The overall incidence of aminoglycoside TDM was 19.26% (N = 135). The highest incidence of TDM occurred in ICU patients (n = 31; 51.61%). Drug monitoring was not consistently conducted in elderly (≥65 years) patients, or in those with signs of renal impairment; even though interviewed physicians and pharmacists identified elderly and renally impaired patients as “high risk” patients. Challenges regarding implementation of aminoglycoside TDM were explored. A lack of competent staff and time constraints were identified as major barriers to quality TDM services. Conclusion: The daily practices and TDM challenges at the site were considered during the design of the aminoglycoside TDM model, which can potentially facilitate better execution and monitoring practices for aminoglycosides at the private hospital. , Thesis (MA) -- Faculty of Health Sciences 2022

- Description: In the process of achieving social equity and local development in Ghana, the empowerment and improvement of the lives of women remain critical factors, because of the existing role women and girls assume in the household and larger communal setting. In Northern Ghana culture and religion have historically side-lined, and in some cases, completely excluded women from participating in the dialogues, economic and political processes that lead to, or facilitate the transformation and development of their households and communities. Even though the media has largely contributed to the discrimination and stereotype of women through how women are represented in mainstream media, the Ghanaian media, in its assumed role as the “fourth estate of the realm” has the power to explicitly advocate and implicitly frame messages which can accelerate the processes of social change, women’s empowerment and social inclusion through the community radio broadcast system (Diedong, 2017: pp. 59, 64). After 30 years of the liberalization of the Ghanaian media and 25 years after the opening of the first community radio station, there have been few studies of how community radio influences women’s empowerment, how it gives opportunity for women to participate in political processes and whether, and how, it strengthens the livelihood capabilities of women. This research was motivated by the empowerment theory and the theory of participatory development communications. The researcher also makes references to feminist media theory in his arguments about the need for women to have access to radio in order to make their own content and also listen to content produced by other women. This study adopted a mixed methods research approach and collected data through programme analysis of the sampled radio stations, focus group discussions and semi-structured interviews. After field data was collected, they were analysed in themes that focus on the objectives of this study, data is presented through thematic discourse methods in order to help the researcher draw conclusions and propose a framework to guide practitioners in the implementation of communication for development projects which use mass media in targeting women for development objectives. My analyses are broadly presented in three chapters with each chapter focusing on one research objective. Based on the data, the researcher discovered that, community radio improves the livelihoods of women in Northern Ghana by providing them with agricultural programming which teaches women new farming techniques and how to practice sustainable agriculture while improving the yield of their crops. The study also found out that community radio provides. opportunities for women to monitor how public funds meant for community development projects are allocated, disbursed, and used for their intended purposes, by creating an avenue of two-way communication and dialogue between women, their district officers, and their elected leaders. Based on the findings of the study, the researcher concludes that, it is important for development practitioners who use mass media to implement women-focused projects to conduct a contextual analysis of the communities, the women, and the identified stakeholders of the intended project because every community is unique. Whereas all women in rural areas are vulnerable and underprivileged. To some extent, their needs and preferences are different because of their different levels of education and income status. , Thesis (PhD) -- Faculty of Humanities, School of Language and Communications, 2022

- Description: Good corporate governance is one of the fundamental principles that enhance the efficiency and sustainability of any entity. It enables an entity to create value for its various stakeholders. This study focuses on the socio-economic impact of poor corporate governance of South African state-owned entities, particularly Eskom, Transnet and South African Airways since the democratic dispensation. The study examines the root cause of poor corporate governance and provides recommendations to address the root cause. Eskom, Transnet and South African Airways, like many other state-owned entities have a significant role in the country’s socio-economic development and yet in recent years they have made news for wrong reasons. There have been numerous reports of poor corporate governance which resulted in the establishment of a Commission of Enquiry into state capture. Two of the three parts of the report of the Commission suggest that poor corporate governance is prevalent in these entities. Some of the root causes that were evident are excessive political interference, ineffective leadership and conflicting governance legislation. This has come at a huge cost to the socio-economic objectives of the government. The future existence of these entities is under treat. There have been notable instances of retrenchments that came at a time when the rate of unemployment is at a record high. Productivity has slowed down, with prolonged periods of unstable power supply being one of the contributing factors. This has suppressed economic growth. These entities have also cost the fiscus billions of rands in government bailouts, funds which could have been used for other important social or capital investment programmes. Some of the suggestions that have been brought forward to curb the culture of poor corporate governance include legislative reform that will provide certainty in terms of governance and provide clear distinctions between the roles of political heads and administrators in the form of board members, COEs and executives. For the recommendations to be effective there needs to be commitment to ethical leadership on the part of political leaders. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2022

- Description: The crux of this study is an analysis of the relations between corporate power and public policy in South Africa, in the period 1996 to 2014. The study’s focus is on corporate power’s influence on South Africa’s public policy and the various means through which power is exerted by the former to shape and control the latter, through the influence of the public policy process and outcome. The study achieves this by arguing that the GEAR and BEE policies failed to achieve their stated objectives, and instead serve as conduits for the exertion of inordinate public policy influence by corporate power. The study analyses how the placing of ANC leaders on major corporate boards has influenced South Africa’s public policy. The study will also examine the ways in which private corporate donations influence public officeholders in the governing ANC. The study also seeks to explore why the ANC with its seemingly progressive stance and history is susceptible to following neoliberal policies pushed for by political forces largely but not exclusively outside the party in the industries described to be targets of redistribution, mining, energy, and finance. The study asserts that private corporate donations made to the governing ANC have a corrupting effect on public policy and corrode democratic decision making and ultimately the public good. This study presents the argument that the ANC-aligned black political elite was co-opted into the structure of economic dominance with the GEAR and BEE policies and hence the prevalence of neoliberal economic policy in post-apartheid South Africa. The study also addresses the intricate relationship between the corporate and political elite, business, and money in South Africa’s elitist public policy landscape , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2022

- Description: Developing countries, such as South Africa, have been on a mission to reduce corruption, particularly in the public sector, and to collect as much revenue as possible through taxation to fund the government expenditures. Low levels of corruption, preferable zero and higher tax collections, can boost a country's economic growth and development by creating jobs and increasing economic activity, which leads to economic growth. South Africa is one of the economies that are characterised by high levels of corruption. For South Africa to attract more foreign investors in the country, it should ensure that resources are used efficiently and that any act of corruption is punished. This study looked at the effects of taxation and corruption on economic growth from 1975 to 2019. An econometric analysis technique was used in the study to test the impact of taxation and corruption on economic growth. The augmented Dickey–Fuller method was used to test for unit root. According to the results of the tests, unit root l(1) is rejected in favour of the stationarity alternative. The empirical analysis used the Autoregressive Distributed Lag Model (ARDL) bounds testing approach of cointegration advocated by Pesaran, Shin, and Smith (2001) to examine for the longrun equilibrium among taxation and corruption on economic growth. The Wald causality test was also used to investigate the causal relationship between taxation, corruption, and economic growth. According to the Bounds test results, there is long-run co-integrating positive relationship between trade openness and GDP, gross capital formation, Corruption, and income taxation.

- Description: Developing countries, such as South Africa, have been on a mission to reduce corruption, particularly in the public sector, and to collect as much revenue as possible through taxation to fund the government expenditures. Low levels of corruption, preferable zero and higher tax collections, can boost a country's economic growth and development by creating jobs and increasing economic activity, which leads to economic growth. South Africa is one of the economies that are characterised by high levels of corruption. For South Africa to attract more foreign investors in the country, it should ensure that resources are used efficiently and that any act of corruption is punished. This study looked at the effects of taxation and corruption on economic growth from 1975 to 2019. An econometric analysis technique was used in the study to test the impact of taxation and corruption on economic growth. The augmented Dickey–Fuller method was used to test for unit root. According to the results of the tests, unit root l(1) is rejected in favour of the stationarity alternative. The empirical analysis used the Autoregressive Distributed Lag Model (ARDL) bounds testing approach of cointegration advocated by Pesaran, Shin, and Smith (2001) to examine for the longrun equilibrium among taxation and corruption on economic growth. The Wald causality test was also used to investigate the causal relationship between taxation, corruption, and economic growth. According to the Bounds test results, there is long-run co-integrating positive relationship between trade openness and GDP, gross capital formation, Corruption, and income taxation. Furthermore, when dependent variable was tested for longrun impact, the results confirmed that taxation and corruption have insignificant impact on economic growth. Trade openness, as a percentage of GDP, has insignificant positive relationship with economic growth in South Africa. Gross Capital Formation, as a percentage of GDP, is positively related to economic growth. Furthermore, short-run findings suggest a positive significant relationship between trade openness as a percentage of Gross domestic product. Corruption and income taxation have negative and insignificant effect on GDP in the short term. Furthermore, GDP and gross capital formation have negative relationship. V Government should also encourage the culture of transparency and accountability as far as corruption is concerned to stimulate economic growth. This will also create a culture where government officials are called upon to explain their government expenditure patterns and be held accountable for any misuse of any funds flowing into the country. , Thesis (MCom)-- Faculty of Business and Economic Science, 2022

- Description: On 23 March 2020, the onset of the Covid 19 Pandemic in South Africa brought with it anxiety, uncertainty and volatility. Change was forced upon everyday life in an unprecedented way. The aim of this study was to determine how professional practices in the built environment are adapting to the forced changes from the perspective of spatial design, functionality and perception. By means of literature reviews and survey responses, insight can be obtained as to the effect of the forced changes on professional practices in South Africa. The effect of the changes and how they are being adapted to, and implemented within the built environment, becomes important, in order to fully understand such changes, from the point-of-view of quality-control mechanisms, skills and knowledge transfer and communication. A mixed-use research approach was used to gather the data; and the outcome of the study aims to identify how the forced change fully affected work-place practices and the people in them. An initial pilot questionnaire was circulated to a small group of professionals in the built environment. Following this, a web-based survey was distributed via the professional-practice governing bodies to Architects, Engineers and Quantity Surveyors within South Africa. Both professionally registered and candidate professionals were invited to participate in the survey. A low response rate of 31% was received. The data from the 47 respondents were captured on the data base. The data were then analysed by the researcher; and by a semantic approach, themes and trends were identified and assumptions were made, based on the results. The respondents identified with the forced changes; and it has emerged that the forced changes are only implemented when necessary or legislated. It was also evident that the remote working environment is not conducive to productive work flow, skills development and quality control in the built-environment sector. The study further makes recommendations, based on the objectives identified. , Thesis (MA) -- Faculty of Engineering, the Built Environment, and Technology, 2022

- Description: In democracies and purportedly free market economies, questions of “who gets what, when, and how” ought to be resolved mainly through free competition, where those with the competitive advantage on merit are guaranteed to succeed. If it is political parties, they only have to compete well and fairly to win elections. If it is businesses, they ought to have the best value and price and they win customers. However, there are institutions which regulate this competition and political economic behaviour. Interest groups such as business chambers, industry and professional associations, as well as various structures of representation engage in the political economic space to sway the distribution outcomes from these “institutions” in the favour of their members. To do so, at times they use methods that affirm the principles and spirit of free competition and at other times, they do not. This thesis reviews the political economy of transformation within the construction sector in Nelson Mandela Bay to further advance knowledge within the subfield of political economy in South Africa. By looking at a specific economic sector, the study adds an important element to the sub-discipline, a nuance to the debates about the role of the state in the economy or macroeconomic policy and the much studied mining-energy complex. The study focuses on the role of small business forums created mostly by newcomers within the construction sector in the city and the methods they used to increase the share of their members in construction sector revenues. Their methods were unconventional and earned them the unfavourable term of ‘the construction mafia’. Through a grounded theoretical research process, this study details the story of the rise and fall of forums and dissects it in line with ongoing debates within political economy and related disciplines, particularly about the nexus between politics and business as well as the role of interest groups in pluralist political systems. Among other things, the study finds that the forums did not see the construction industry as a free market and did not take principles of competition in the sector as a given. As such, they sought to make and remake institutions of the sector in ways that could increase their share of revenues. In similar fashion to the roles of iinjoli nosokhaya in traditional isiXhosa ceremonies, they accorded to themselves the right to distribute benefits to their members contrary to legal and general market prescripts. , Thesis (PhD) -- Faculty of Humanities, School of Government and Social sciences, 2022

- Description: Gqom music has grown from being a relatively obscure sub-genre of South African Kwaito into a globally recognised sonic identity and social movement. Gqom, as a distinct music style, has featured heavily in mass media since 2015, spawning social phenomena such as viral dance challenges on various social media platforms, and constituting a launch pad for the careers of musicians such as DJ Lag and the Distruction Boyz. Gqom also featured in the international motion picture Black Panther in 2018, and in the 2019 Lion King: The Gift album by American pop icon Beyoncé. Although the origins of Gqom, its characteristics, impact, and ascension to noteworthiness have received attention in the form of newspaper articles, online blogs, YouTube documentaries, etc, and small treatises or academic articles, little literature has been generated about the music and its theoretical construction as sonic and social phenomena. I argue that by using the theoretical scaffolds of ‘identity politics’, specifically ‘identities in music’, one is better able to understand Gqom as reflective of a broader social urban youth identity characterised by partying and political disillusionment. In other words, I make the case for an intergroup identification that prioritises in-group musical identities associated with Gqom and its phenomenology of practices which I have excavated using an ethnographic qualitative method. , Thesis (MMus) -- Faculty of Humanities, School of Visual and performing Arts, 2022

- Description: I investigated potential links between the diversification of African primate lineages and the physical evolution of the continent. I compared published phylogenetic trees based on mitochondrial and nuclear DNA for five clades: (a) Lorisoidea (galagos and pottos); (b) arboreal guenon monkeys (Cercopithecus and its allies); (c) living apes (including humans); (d) Papionini (baboons); and (e) savanna or “vervet” monkeys (Chlorocebus). I compared primate divergence dates with the ages of tectonic events, patterns of climatic change, and their palaeo-vegetational consequences. Based on present primate distributions, I estimated likely geographic locations of the divergence events. Finally, I compared the phylogenetic patterns of the primate clades with hominin evolutionary scenarios. Phylogenetic comparisons indicated three time periods when rates of speciation increased across the five primate clades: the Eocene – Oligocene transition (34 – 32 Ma); the mid-late Miocene (10 – 5 Ma); and the Pliocene – Pleistocene transition (2.7 – 2.3 Ma). Concentrated bursts of lineage splitting indicate a broadscale causal relationship between environmental change and lineage divergence. Human evolution followed similar biogeographic patterns to those of other primate clades. Tectonic events, climatic changes and palaeo-vegetational shifts are intimately connected, and have synergistic effects on biotic diversity. Tectonic events influence climatic change through their effects on oceanic circulation, planetary temperatures and rainfall patterns. Additionally, tectonic uplift and erosion may create geographic barriers to organismal dispersal across the continent, increasing the likelihood of geographic separation of populations and speciation. Recently evolved primate species show high levels of hybridisation for several generations after their initial divergence. Genus Homo generated ~10 species over 2.5 Ma. The emergence of these taxa likely involved substantial hybridisation, as demonstrated by the presence of Neanderthal genes within the H. sapiens genome. I suggest that this hybridisation contributed to the difficulties palaeoanthropologists often experience in distinguishing fossil hominin taxa. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022
