  • Description: The last 'Trial Update" reported on Comrade Moss’s case until mid-March. This report covers the period from that time up until 25th April.STADLER - "ANC EXPERT" Brigadier Stadler testified that the ANC had made certain calls to organisations within the country which, according to his "research", had been followed by organisations in the country. As examples he gave the ANC’s call for ungovernability, the formation of organs of people’s power and the destruction of town councils. During cross-examination Stadler conceded that he was not able to give examples of any direct link between the ANC and organisations inside the coutry but he said an inference could be drawn by looking at the ANC’s call and the behaviour of organisations inside the country.

  • Description: Background: Insufficient iodine intake in pregnancy is associated with many adverse pregnancy outcomes. About 90% of African countries are at risk of iodine deficiency due to poor soils and dietary goitrogens. Pregnancy predisposes to insufficient iodine nutrition secondary to increased physiological demand and increased renal loss. Iodine deficiency is re-emerging in countries thought to be replete with pregnant women being the most affected. This review seeks to identify the degree of iodine nutrition in pregnancy on the entire African continent before and after the implementation of national iodization programmes. Methods: A systematic search of published literature will be conducted for observational studies that directly determined the prevalence of insufficient iodine intake among pregnant women in Africa. Electronic databases and grey literature will be searched for baseline data before the implementation of population-based iodine supplementation and for follow-up data up to December 2018. Screening of identified articles and data extraction will be conducted independently by two investigators. Risk of bias and methodological quality of the included studies will be assessed using a risk of bias tool. Appropriate meta-analytic techniques will be used to pool prevalence estimates from studies with similar features, overall and by major characteristics including the region of the study, time period (before and after implementation of iodization programmes), sample size and age. Heterogeneity of the estimates across studies will be quantified and publication bias investigated. This protocol is reported according to Preferred Reporting Items for Systematic reviews and Meta-Analysis protocols (PRISMA-P) 2015 guidelines. Discussion This review will help ascertain the impact of national iodization programmes on the iodine nutrition status in pregnancy in Africa and advise policy on the necessity for monitoring and mitigating iodine deficiency in pregnancy in Africa. This review is part of a thesis that will be submitted to the Faculty of Health Sciences, University of Cape Town, for the award of a PhD in Medicine whose protocol has been granted ethics approval (UCT HREC 135/2018). In addition, the results will be published in a peer-reviewed journal.

  • Description: In recent years, the concept of entrepreneurial ecosystems increased in status amongst policy makers, scholars, practitioners, and mainstream media as a regional economic development strategy. Yet, despite the opportunities presented by the entrepreneurial ecosystem, it is both under-theorized and lacks data on a sub-national scale. Furthermore, research from an African and sub-Saharan African context remains in its infancy. The limited research within these resource-constrained countries creates a challenge to determine the underlying factors that influence entrepreneurship. As a result, developing economies, as in the case of sub-Saharan Africa, have applied generalizations of the entrepreneurial ecosystem, which undermine the temporal differences of places and reduce the potential to benefit from agglomeration economies. With the National Development Plan: Vision 2030, the South African government strives to achieve an inclusive economy through enhancing the capacity of the state, building capabilities, and promoting partnerships amongst sectors. Motivated by the mandate to redress the inequality caused by economic exclusion, the South African government has taken counteractive measures focused on promoting entrepreneurship as a key driver of economic growth. Despite the measures placed, South Africa struggles with high levels of inequality with a Gini coefficient of 0.63, unemployment of 32.6% and negative GDP per capita growth of - 8.137%. Furthermore, most small businesses in South Africa are informal, which means that a disproportionate concentration of employment exists in the informal sector. Against this backdrop, the problem addressed in this study is based on the challenge of creating productive entrepreneurship that acknowledges the unique structure and resources of Nelson Mandela Bay. To address this gap, a critical inquiry into entrepreneurial ecosystems was motivated. First, the inquiry is focused on a real-world context, namely Nelson Mandela Bay, which is one of the eight metropolitan regions in South Africa, a developing economy. Second, the inquiry uses multiple perspectives through multiple data collection methods. To commence the inquiry, a literature review was conducted on secondary sources to identify the factors influencing entrepreneurial ecosystems and formed the basis of the theoretical framework. The study followed the pragmatism research philosophy and used an abductive research approach. A mixed method research design was utilized and followed a sequential independent process, which was performed in two phases and independently analyzed. , Thesis (DBA) -- Faculty of Business and Economic Sciences, 2021

  • Description: Climate change continues to pose a threat to mankind. Its impacts are evident in both developed and developing countries. South Africa is a no exception to the climate change problems. Climate change in South Africa has affected water availability which subsequently affects food security of the country. This research study investigated the impacts of climate change on food security in South Africa. South Africa’s food security is severely affected by climate change and as a result, the South African government through the Department of Agriculture, Forestry and Fisheries has devised strategies to respond to climate change and ensure food security in the country. The study analysed government documents and articles about climate change from 2008 to 2018. The study employed content analysis as a data analysis method and the study developed eighteen codes and from those codes, four themes emerged. The research findings highlight that South Africa is a food secure nation only at a national level. In addition, the findings highlighted that climate change poses a significant threat on the agricultural sector which ultimately affects food security in South Africa. The climate change impacts in South Africa include an increase in temperatures, rise in sea water levels, and floods. Climate change in South Africa continues to pose a significant threat in the GDP as it affects crop production and livestock farming, which ultimately affects the exports of the country. , Thesis (MA) -- Faculty of Business and Economic Sciences, Economics, Development & Tourism, 2021

  • Description: In this thesis, we present adsorptive removal of nitrogen-containing compounds from fuel oil as an alternative to complement conventional hydrotreatment to obtain ultra-low sulfur and nitrogen levels. This is in cognizance of the challenges nitrogen-containing compounds pose to the hydrotreatment process, particularly their inhibition and/or poisoning of the catalysts used in the process, of which basic nitrogen-containing compounds are the major culprits. Selectivity is the biggest challenge for adsorptive removal of nitrogen-containing compounds. We explore reticular synthesis of metal organic frameworks and the use of coordinatively unsaturated metal sites in 1-dimensional coordination polymers to achieve good selectivity for nitrogen-containing compounds. In the first part of the thesis, reticular synthesis of metal organic frameworks to control the size of the cavity, and strategically use the linkers and metal centres was envisaged. In this work we explored variation of the metal centres in the secondary building units (SBUs of the MOFs as the first step to the testing and implementation of the design strategies. Carbazole, representing carbazoles which the major compounds that remain in hydrotreated fuel, was the target compound. Four MOFs of zinc (Zn-CDC-bpe), copper (Cu-CDC-bpe), nickel (Ni-CDC-bpe) and cobalt (Co-CDC-bpe) based on the formation of a dinuclear metal paddlewheel SBUs with the ligand 9H-Carbazole-3,6-dicarboxylic acid (H2CDC) and occupation of the axial positions of the paddlewheel by 1,2-Bis(4-pyridyl)ethane (bpe) to form porous networks were synthesized. A fifth MOF containing only CDC which forms a [Zn4O(O2C-R)5(O2HC-R)] SBU was also synthesized (Zn-CDC). The ligand H2CDC was inspired by the possibility of improving selectivity for carbazole via π–π interactions through the more preferred parallel-offset stacking as well as the possibility for further substitution of the carbazole N-H to add groups that improve selectivity. The sizes of the MOF cavities can then be controlled by choosing different lengths of ligands analogous to 1,2-Bis(4-pyridyl)ethane (bpe), e.g. 4,4’-bipyridine and pyrazine. All the MOFs showed good selectivity of carbazole. The Zn-CDC MOF also had good selectivity for the basic nitrogen-containing compounds tested: quinoline, isoquinoline, quinaldine and 1-naphthylamine. Its uptake of carbazole was also slightly higher. This was attributed to the presence of an unsaturated Zn site in the SBU. Adsorption in all the MOFs was primarily due to physisorption. It was concluded that the role of the metal centre does not play a significant role in the adsorption of carbazole besides providing a template for reticular synthesis. , Thesis (PhD) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2021

  • Description: Over the past decades there has been a drastic decline in our ocean’s health that has resulted in fish depletion as well as marine life endangerment. This is largely due to human and economic activities such as commercial fishing, ship to ship bunkering and dumping of waste material at sea. The lack of governance and law enforcement has been a catalyst to the ocean’s fast approaching death. Although many laws and legislation exist to direct and encourage appropriate behaviour to preserve the ocean and marine life as well as ensure equality and equal access, the follow through and adherence have been lacking. This study was guided by the aim to develop a strategy for the implementation of a corporate governance framework to enhance compliance to environmental legislation in Algoa Bay to better protect the ocean, marine life and the rich biodiversity in the region which in extension will be beneficial to society and the oceans economy, as a thriving ocean is good for fishing, investments, imports, exports and tourism which is crucial for a booming oceans economy. The methodology applied in this research is a qualitative approach that used semi- structured interviews targeted at owners and managers of organisations to extract data regarding the level of compliance by those operating in the Algoa Bay region to marine and environmental legislation to decipher where decision making leaned and if it was slanted more towards non-compliance. The findings of the study demonstrate that organisations are not fully compliant to marine and environmental legislation despite being environmentally aware and portraying themselves as such to the public. This has been largely due to poor law enforcement practices and organisations valuing profit over compliance. As a result, African Penguins and many other fish species have become endangered. A corporate governance framework to enhance compliance will benefit society and promote job creation by employing more law enforcement agents to ensure the laws are being adhered to which will improve the socio-economic state for Algoa Bay and preserve the biodiversity and marine resources. , Thesis (MCom) -- Faculty of Business and Economic Sciences, 2021

  • Description: The empirical study investigates the relationship between inflation, credit markets and economic growth in the context of Brazil, Russia, India, China and South Africa (BRICS) countries. The BRICS group consists of five emerging market economies and was first coined by Jim O’Neil of Goldman Sachs in 2001 whereby initially the bloc consisted of only Brazil, Russia, India, China, South Africa joined the BRICS group in 2010. The BRICS bloc was deemed to be the top fast-growing economies that showed great potential for growth. Consequent to the 2008 global financial crisis, there has been a large change in economic thinking as policy-makers have struggled to overcome the economic misfortunes caused by the crisis. Amongst the emerging countries, the BRICS countries have in effect, established a New Development Bank to play the role of the credit facilitator the BRICS countries and other emerging countries as well. This BRICS New Development Bank was established in 2014 and already has identified and funded some projects within the BRICS countries. Moreover, the main objective of this bank is to provide credit to be utilised for infrastructure, climate change measures, as well as to ensure sustainable development. Against this backdrop, the current study investigates the role played by credit and the extent of development in credit markets on enhancing growth in the BRICS countries, particularly looking at the levels of inflation that are conducive to credit market development. The study notes that in order for credit expansion to be successful, the credit received by a country must reflect positively on a country’s economic growth. In other words, with more credit coming into a country, the expected result is that there will also be a rise in economic growth. Furthermore, seeing that inflation erodes the value of money, this credit or these funds that a country receives may not have the expected influence on growth. Therefore, the study finds it imperative to investigate the levels at which inflation allows for credit expansion to promote growth in a country. Furthermore, central banks play an important role in credit markets via the interest rate channel and the study examines the role of monetary policy in credit markets of each of the BRICS countries by looking at the inflation targeting regime as well as the absence thereof within these countries. Moreover, BRICS central banks share more or less the same goal of maintaining price stability and low inflation through various monetary policy tools. Therefore, achieving this objective will allow a central bank to gain both investor and consumer confidence which plays a role in a country’s investment rates. Moreover, inflation that is not controlled results in uncertainty which makes investors hesitant and unwilling to embark on investments. Ha, Ivanova, Ohnsorge and Unsal (2019) associate a developed financial sector with low inflation, stating that stable inflation rates eliminate uncertainty and avoids the erosion of the value of money. The current study used an Autoregressive Distributed Lag (ARDL) model to examine the linear co-integration and Non-linear Autoregressive Distributed Lag (NARDL) for the non-linear empirical analysis of the relationship between inflation, credit markets and economic growth in BRICS countries. The non-linearity of this relationship is important to study as there has been many debates on the nature of the inflation-growth relationships with some studies implying that it is positive, some say it is a negative relationship and some say it is non-linear. The annual data time series is extracted from the World Bank Indicators and the Penn State database covering the period 1960-2019. The main variables used in the study are Inflation (CPI), Credit (Domestic Credit to Private Sector) and Economic growth (GDP). The study conducted various regressions including the total of five linear regressions which were run individually for each country, the non-linear regressions consisted of three regressions for each country which were on 1) Only Inflation partitioned, (2) Only Credit partitioned and (3) both Inflation and Credit were partitioned. The partitioning of the variables is made possible by the NARDL model which allows variables to be partially decomposed into negative and positive sums to identify thresholds of variables which have various effects on other variables. The overall findings of the study suggest that although inflation exerts various effects on growth, according to this study’s results, it does not have a significant impact on credit for all the countries except for China whereby credit in general is conducive to economic growth and Brazil where growth is enhanced when credit is declining. The study revealed that generally, inflation exerts a negative impact on growth, therefore, authorities must focus on keeping inflation rates low particularly for Russia, India and South Africa as Brazil’s results suggest that rising inflation is conducive to its economic growth in the long run. According to the findings of this study, credit does not have the significant impact on growth even under different inflation thresholds. Furthermore, this does not imply that the credit channel is a futile tool for authorities, the relationship between inflation, credit and growth particularly with the hypothesis that inflation enhances credit market development and therefore growth, is not significant. , Thesis (MCom) -- Faculty of Business and Economic Sciences, School of Economics, Development & Tourism, 2021

  • Description: The mobile telecommunications industry has been a fundamental and an important enabler in the advancement of the South African economy, with mobile network providers investing billions of rands in mobile infrastructure and facilitating a functional and progressive global marketplace (ICASA Annual Performance Plan, 2020/21). South Africa’s telecommunications system is one of the most sophisticated in the emerging markets, and according to Gillwald, Mothobi, and Rademan (2018, p.6), various indices including the ICT Development Index corroborate this view. The deployment of wireless communications networks in the country has had immeasurable social benefits for many consumers. The most rural areas of the country are now able to experience the convenience and ubiquity that comes with having access to mobile network technology. Though mobile network provision is making progress in terms of bridging the digital divide, inhibitors exist within the mobile competitive landscape that prevent consumers from exploring the full benefits of the advanced technologies at their disposal. According to Chinembiri (2020, p.6), mobile data costs remain high and out of reach for the average South African consumer, despite the recent requisite data price reduction by the dominant mobile network service providers. The prepaid segment is dominated by customers who either carry multiple SIM cards or switch between mobile network operators. The adoption by ICASA of the Mobile Number Portability (MNP), the process through which customers switch between mobile operators and keep their mobile number (Yadav, Dabhade, & Dabhade, 2013, p.1), resulted in significant reduction in switching costs thus perpetuating the migration of subscribers between mobile network providers. According to Olufemi and Strydom (2018, p. 52), the fiercest competition experienced by South African mobile providers is in the prepaid market. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2021

  • Description: Upwelling, bay-scale currents, fronts and mixing in Algoa Bay and St Francis Bay occur over both short and long time periods. These physical ocean dynamics drive the temporal and spatial distribution of nutrients in the bays, there by influencing primary and secondary production. Thermal gradients and fronts are driven by the wind and open ocean influences, such as the Agulhas Current, daily and seasonal variations in solar radiation, long and short period waves, air-sea fluxes, coastal trapped waves and terrestrial freshwater inflow. These phenomena are poorly understood along this part of the coastline and were the focus of this study. I investigated the dominant temperature scales of variability in both bays, to determine which isotherm is best suited to describe temperature fluctuations and thermocline spatiotemporal variability in and between the two bays. I investigated upwelling spatiotemporal variability in the two bays and tested whether upwelling occurs at the opposite sides of the bays with a change in wind direction. Thereafter studied the occurrence and drivers of winter upwelling events. The wind-driven current spatiotemporal variability and correlations were investigated at the extremities of the two bays. The daily, intra-seasonal and yearly variation in temperature structures in Algoa Bay and St. Francis Bay were mainly driven by the local winds, coastal topography, and bathymetry. The most suitable isotherm to describe thermal fluctuations and variability in Algoa Bay shallower sites was 16.5 °C and its mean depth was 16.2 m. The best isotherm for the deeper sites in Algoa Bay was 15.7 °C with a depth of 33.1 m. The average temperature and depth of the best isotherm to describe thermal fluctuations in St. Francis Bay for the shallower sites was15.80 °C and 16.83 m, and for the deeper sites it was 15.10 °C and 32.08 m. Algoa Bay showed an average cooling trend of -0.000172 °C per year, whereas in St. Francis Bay a warming average trend of 0.0188 °C per year was observed over the study period often and six years, respectively. The wind, Coriolis Effect and Ekman Transport were the main external forces that influenced upwelling throughout the year. Since the available mesoscale indices for upwelling intensity lack the resolution needed to characterize and compare inner-shelf upwelling regimes at small spatial scales, I developed a new local, quantitative index of thermal variability. Index calculations were based on hourly records of in site depth-averaged temperatures, measured at 6 sites in St. Francis Bay and at 8 sites in Algoa Bay. Using the Multivariate Upwelling Zone Index of Cooling (MUZIC) I found that Woody Cape and Blue Horizon Bay had the highest upwelling intensity in Algoa Bay and St. Francis Bay, respectively. The other sites were ordinated and ranked according to their upwelling rates and intensity. Evidence of wind-driven winter upwelling was found to be a common occurrence in both bays. There was no obvious current seasonality observed, however, strong spectral signals in the period of a weather band (4 –7 days) were present. Current structures were generally positively correlated with wind variations in both bays. Thus, when westerly/easterly winds blew the overall surface current direction was eastward/westward. I observed a pronounced current spatiotemporal variability that was driven by local winds. The Bird Island surface currents in Algoa Bay were strongly correlated at 0–lag day with the winds, however, in Cape Recife the strongest correlations were usually observed at 1–lag day highlighting the spatiotemporal influence of wind regimes on current structures in Algoa Bay. Bird Island current speeds were higher and had an obvious bimodal directional variation (south westward /north eastward) compared to Cape Recife currents, which generally had a slower current speed with a strong west-north westward direction. In St. Francis Bay, the Schoenmakerskop surface currents showed weak positive correlation with winds at 0–lag day, however, stronger negative correlations were observed at 4–lag days. The current surface speeds in Schoenmakerskop were the lowest and varied directionally between north-north eastward and south-south eastward. The basic data requirements (i.e. SST/ UTR and ADCP time series) and the simplicity of the calculations make these indices a useful tool to apply to a large number of sites nationally and internationally, and to examine the generality of community and population-level responses to physical forcing. , Thesis (PhD) -- Faculty of Science, Journalsim and Media Studies, 2021

  • Description: The present study aimed to investigate perceptions of small-scale vegetable farmers on drought mitigation strategies in the Amathole District Municipality of the Eastern Cape Province. The research objective was to investigate what small-scale vegetable farmers’ perceptions and readiness are in terms of strategies to cope with drought conditions. The study was conducted within the Mbashe, Mnquma, Amahlathi and Great Kei local municipalities of the Eastern Cape. Primary data collection was conducted among 44 small-scale vegetable farmers of the Amathole municipal district. These are farmers who receive social support from the government, are registered with the Department of Rural Development and Agrarian Reform and contribute to the fight against food insecurity in the Amathole district. The primary data was also collected from 13 agricultural extension officers with high experience in advising small-scale farmers residing in the Amathole district. Data collection took place in various local municipalities under Amathole District Municipality, namely: Mbashe, Mnquma, Amahlathi and Great Kei. A multi-method approach was adopted in this study as an appropriate technique to create an improved quality of research which eliminates the deep-rooted bias to either qualitative or quantitative methods alone. A self-administered questionnaires with both closed and open-ended questions – one for the small-scale farmer survey and the second for the extension officer survey – was employed as data collection instrument. The demographic characteristics of small-scale vegetable farmers in the survey area indicated that the present majority of farmers are married male Xhosa farmers between the ages of 56 and 65 years old, with a secondary level of education. The majority of the farmers are typically resource-poor − which implies that the added menace of drought poses the risk that small-scale vegetable farming could decline to mere subsistence level or worse. Drought was found to be a major problem in Mbashe, Mnquma, Amahlathi and Great Kei local municipalities within the Amathole municipal district, with an acute impact on farmers’ production and generation of income. From the data, it emerged that farmers are not sufficiently informed about and do not receive specific training in drought mitigation strategies. Farmers rely on drought alleviation methods but there is a lack of adaptive strategies and timely, long-term ii state intervention. Being resource-poor, these small-scale producers are reliant on natural resources – notably water for irrigating crops. The study established further that there is neither the resources nor sufficient training by and involvement of the extension service. Farmers therefore rely on the use of drought coping mechanisms and drought mitigation techniques and on adapting their production systems. The information-sharing sessions recommended can assist in improving rural livelihoods and the productivity of small-scale vegetable farmers. The absence of engagement of youth in farming means that modern conservation and innovative farming techniques and systems are not implemented towards reducing the impacts of climate change − as well as revitalizing rural areas such Amathole. Access to education about drought, improved drought coping mechanisms and adaptive strategies should be created to facilitate an exchange of traditional and modern agricultural information. The development of infrastructure in rural communities and farming areas is another factor crucial to improving farming systems and operations in the Amathole municipal district. , Thesis (MSc) -- Faculty of Science, School of Natural Resource Management, 2021

  • Description: Throughout history entrepreneurship has played an integral part in society. It improves standard of living, develops new markets, and puts ideas into effect while fostering economic growth and job creation. Over the recent years, the countries around the world have experienced unprecedented economic meltdowns. Economic events and prospects in industrialised countries like Europe, Asia, and America have a direct and immediate impact on developing countries, particularly Africa. Positive economic growth of Africa's key trading partners has a direct impact on the continent's economy. Africa's key trading partners' negative economic growth has unfavourable effects for the continent's economy. This was recently further exposed and exacerbated by the novel Corona virus pandemic. The worldwide economic crises have resulted in global financial melt downs, volatile exchange rates, fluctuating steel prices, soaring labour costs, and more importantly competitiveness in markets. In South Africa this has contributed to very high rates of youth unemployment, stagnant economic growth, volatile socio-economic environment, and high failure of small, medium, and micro enterprises (SMMEs) amongst other factors. South African SMMEs have been identified as key role players and drivers for job creation; the industry already absorbs most of the employed population. They are a potential mechanism for creation of new and sustainable employment opportunities. Furthermore, they contribute to the Gross Domestic Product (GDP) of the country yet experience a high failure rate. A successful enterprise has a massive social impact and economic contribution in a country. It is therefore indisputable that the field of entrepreneurship has received immense academic interest. The current Volatile, Uncertain, Complex and Ambiguous socio-economic environment necessitates strategies that are aimed at the growth, innovativeness, adaptability, and agility of entrepreneurs and SMMEs. This will enable them to reach their full potential and effectively deliver on job creation and economic growth. The purpose of this research treatise is to develop a development framework for SMMEs and entrepreneurs in the Nelson Mandela Metro. This was achieved by applying academic insights and an extensive literature review on personality traits of entrepreneurs, the internal and external environment, and their contribution to the success of entrepreneurial ventures, which has led to the development of research propositions. The study is quantitative research on 45 SMMEs from the Nelson Mandela Metro. It contributes positively to the academic field of entrepreneurship, SMMEs and to the existing academic body of knowledge with a positive contribution on entrepreneurial traits, business development, strategy formulation and strategy implementation. , Thesis (MBA) -- Faculty of Business and Economic Sciences, 2021

  • Description: Increasingly, students across the world in various tertiary institutions are faced with many challenges ranging from financial difficulties, accommodation, academic exclusion and many other challenges. Subsequently, the students’ academic performance suffers due to these challenges. This thesis therefore aims to focus on the perspectives of the post-graduate students at the Nelson Mandela University regarding the notion of wellbeing. This thesis attempts to uses a sociological indigenous perspective of wellbeing of “impilo” in describing well-being. Therefore, the thesis uses wellness as a conceptual framework to understand the challenges faced by postgraduate students at Nelson Mandela University. The thesis was conducted in Port Elizabeth, at Nelson Mandela University campus of Summerstrand focusing on post-graduate students in faculty of humanities. A qualitative research design and qualitative digital ethnographic research methodology was chosen as suitable for answering the research question. Data was collected using semi-structured interviews and transcribed verbatim. Data analysis included identifying consistent themes around notions of well-being and experiences of changing university culture in the responses. The thesis main findings reveal the impact of how the changing university institutional culture impacts post-graduate student’s wellbeing.The research found that students are affected by institutional cultures and this is narrated through their experience of university life and their reflections on #MustFall movements. The participants have detailed how the cultures in the university have a greater impact on the well-being on student because the university is more than just a place of learning but their home. The participants also detailed new colloquial ways of describing well-being using the term “inerves” and “umgowo” are general ways of describing their well-being. The dissertation has contributed to the limited body of knowledge in the context of post-graduate students experience and conception of well-being in the South African higher education , Thesis (MA) -- Faculty of Humanities, Government and Social Studies, 2021

  • Description: The current globalisation is pressuring both developed and developing nations to fast-track change and development with the intention of improving the living standards of the people. With limited financial resources and razor-thin budgets, national governments now turn to private sector to collaborate in financing infrastructure that is critical for economic and social growth. Despite the increase in public-private partnership (PPP) investments in Zambia, there have not been any formal assessments of the PPPs to evaluate their impact on Zambia’s economic growth and economic development. This research evaluates the impact of PPPs on Zambia’s economic growth (proxied by gross domestic product [GDP]) and economic development (proxied by unemployment, household consumption and Gini coefficient). The research adopts the auto-regressive distributed lag (ARDL) model as the time series approach to investigating the relationship between PPPs and gross domestic product (GDP) as well as the economic development. The ARDL model was also used for evaluating the impact of PPPs on Zambia’s GDP and economic development for the 18 years from 2000 to 2017. Thirty-two self-administered questionnaires (SAQs) were received and seven interviews were conducted with key research informants. The key research informants for both the SAQs and interviews were purposively selected to provide insights into the impact of PPPs on Zambia’s GDP and economic development. The ARDL model results have established that there is a stable and long-run relationship between PPPs and Zambia’s economic growth. Similarly, insights obtained from SAQs and interviews show that PPPs are not only important in Zambia but are related to economic growth. Therefore, Zambia should continue harnessing and promoting viable PPPs to enhance its economic growth. This also entails that private sector should continue providing financial resources and expertise to spur Zambia’s economic activities. Through the use of F-statistics, the ARDL model results reveal that PPPs are cointegrated with household consumption, unemployment and the Gini coefficient. As such the ARDL model results confirm the existence of a stable and long-run relationship between PPPs and economic development. The insights obtained from SAQs and interviews highlight that PPPs in Zambia are important. Furthermore, the insights from the key informants suggest that there is a relationship between PPPs and economic development. Hence, Zambia’s continued harnessing of PPP investments is pivotal in its quest to improve the living standards of ordinary people. Using long-run coefficients, the ARDL model results demonstrate that PPPs impact Zambia’s GDP positively. PPPs have spurred economic activities through the creation of businesses. Similarly, the insights from key informants demonstrate that PPPs relate positively to GDP. The overall results suggest that PPPs impact GDP positively. As PPPs impact GDP positively, the government of the Republic of Zambia should continue harnessing the PPP investments as a pro-poor model that bolsters economic activities and fosters economic growth. The harnessing of PPP investments means that the Zambian government, through its Finance Ministry, should scale up investments in PPPs and widen the scope of sectors for PPP investments so as to achieve inclusive and faster economic growth. The ARDL model results show that PPPs affect economic development positively through increases in household consumption and reductions in unemployment rates. However, the data on the Gini coefficient reveal that PPPs have a negative impact on economic development, as PPPs contributed to the rise in the Gini coefficient for the period under review. The key informants’ insights reveal that PPPs affect economic development positively by increasing household consumption and reducing the unemployment rate and the Gini coefficient. The mixed results on the Gini coefficient data representing income inequalities could be attributed to low-quality jobs and poor employment conditions created through PPP projects. Overall, the study’s results show that PPPs have a positive impact on economic development, as they have created businesses and employment thereby contributing to the increase in household consumption. Consequently, the Zambian government should continue engaging the private sector in PPP projects. The government should also scale up PPP investments and widen their scope to include other sectors of the economy as PPP present a viable option for the continued spurring of economic activities, the creation of employment and improvements in household consumption. The research results suggest that PPPs play an important role in improving economic growth and economic development thereby supporting the original intention of the PPP strategy for both developed and developing countries. The research strongly recommends the scaling up of investments in PPPs to contribute to the reduction or eradication of poverty in Zambia – and in other developing countries in Africa. The scaling up of PPP investments has implications that require attention from policy makers. There is a need for the development and dissemination of PPP policy guidelines to improve the design, development and implementation of PPPs in Zambia. The scaling up of investments in PPPs also requires changes to be made to the current PPP Act to widen the scope of PPP investments so as to include additional economic sectors to increase GDP, improve household consumption, create new jobs and reduce the Gini coefficient in Zambia. As PPP processes are complex, increased investments in PPPs will require further training of the PPP department’s staff, the contracting authorities and the private sector to improve their regulatory and technical capacity in the design, development and implementation of PPP projects. , Thesis (PhD) -- Faculty of Business and Economic Sciences, 2021

  • Description: The South African spearfishery forms a small component of South Africa’s complex coastal fishery. Although the smallest, this fishery sector has the largest proportion of data deficient species, and as a consequence is poorly managed. Oplegnathus conwayi (Cape knifejaw) is an example of one of these species for which there is very little and outdated biological and ecological data. This species is among the top target species by recreational spearfishers in South Africa. This thesis aimed to improve our socio-ecological knowledge of the South African spearfishery through the collection of biological and Fishers’ Ecological Knowledge (FEK) information on Oplegnathus conwayi, and human dimension information on the South African spearfishery. Monthly biological samples were collected through routine sampling (spearfishing) and augmented by recreational spearfishers. A total of 254 fish were collected from the warm-temperate coastal zone (East London – Cape Agulhas), 28 from the sub-tropical zone (Durban – East London) and 23 from the cool-temperate zone (Cape Agulhas – Cape Point). The results indicated that Oplegnathus conwayi is a slow-growing species, with a maximum recorded age of 27 years. The population sex ratio was skewed, with males dominant in the population (1M:0.6F). The length- and age-frequency distributions were, however, similar for both sexes. No significant differences were observed between male and female growth (LRT, p > 0.05), with the overall population growth curve being best described as L(t) = 697.15(1-e-0.06(t-6.30)). Males matured at a slightly larger size than females, however, no significant differences were observed (LRT, p > 0.05). The length- and age- at-50% maturity was 330 mm (FL) and 5.73 years for the full population, respectively. Histological analyses showed that Oplegnathus conwayi are asynchronous spawners with a gonochoristic reproductive style. Macroscopic staging and gonadosomatic index results indicated a protracted spawning season for Oplegnathus conwayi, with a peak in spring. A survey was designed and disseminated to collect FEK on the biology and population status of Oplegnathus conwayi and human dimension information on South Africa’s spearfishery. A total of 103 survey responses were received, of which 94 were regarded as specialised (spearfishers who had greater experience, skill and avidity, and maintained spearfishing as an important component of their lifestyle) spearfishers. Based on the responses of the specialist spearfishers, the top four main species caught by spearfishers from this survey were Seriola lalandi (13.9%), Pachymetopon grande (11.7%), Oplegnathus conwayi (11.4%) and Sparodon durbanensis (11%), and the majority of respondents indicated that there had been no changes in abundance, size and catches of these species in the years that they had been spearfishing. Respondents indicated that Oplegnathus conwayi are most commonly targeted in the Eastern Cape and are found at depths of up to 40 m. Respondents also indicated that there may be a seasonal onshore (Summer/Winter) and offshore (Summer/Winter) migration with year-round spawning and a peak in November, December and January. The incorporation of spearfishers into the data collection, both through the collection of specimens and their FEK, was beneficial to this study. Besides providing samples from a broader geographical range than the primary collection area, the collaboration with spearfishers has promoted the inclusion of this group into the management system. The findings of this study also suggest that FEK data can be more reliable if the concept of recreational specialisation is incorporated into data collection. While the FEK suggested that the population was stable, a stock assessment is necessary to fully understand the population status and implement management strategies. Nevertheless, the key life history characteristics (slow growth and late maturation) observed in this study are characteristic of species that is vulnerable to overexploitation, and thus the precautionary approach should be applied. The reproductive information collected in this study has provided information for the implementation of an appropriate size limit regulation for Oplegnathus conwayi. Here, a minimum size limit of 400 mm TL, which corresponds approximately with the length-at-50% maturity of 330 mm FL, would be appropriate to allow fish to mature and spawn, and reduce the likelihood of recruitment overfishing. Reduction in the bag limit from five to two fish per person per day may also be appropriate as a precautionary measure until a stock assessment has been completed. Finally, the incorporation of stakeholder into biological collection and the use of FEK may be a useful approach for other data deficient species and in countries with limited resources for ecological research. , Thesis (MSc) -- Faculty of Science, Ichthyology and Fisheries Science, 2021

  • Description: This research project constituted as a thesis of limited scope for a Masters in Education Degree (i.e. as 50% of the degree) focusses on a job creation programme named ‘Groen Sebenza’ [Green Work]. Groen Sebenza is an environmental education ‘incubator’ programme driven and implemented by the South African National Biodiversity Institute (SANBI) to unlock green jobs and bridge the gap between education and job opportunities in the biodiversity sector in South Africa. The programme is a key intervention to strengthen biodiversity human capacity development in the biodiversity sector in South Africa, seeking to contribute to transformation of the biodiversity sector, and also address issues of youth unemployment in the country. The young ‘interns’ in the programme were called ‘pioneers’ at the start of the project. This research project explores how a host institution operating as a community of practice within a landscape of practice managed to implement the Groen Sebenza programme by absorbing and appointing all their pioneers into sustainable jobs beyond the pilot project. I sought to better understand the process of supporting and empowering unemployed youth into sustainable green jobs within the Groen Sebenza partnership programme. I drew on Community of Practice (CoP) theory, and its value creation framework to develop this understanding, and I under-laboured the analysis with a social realist analysis of enabling and constraining factors. The unit of analysis of a Community of Practice was a useful focus for the study, as these mentors, managers, and administrators were all involved in supporting the empowerment and retention of the young pioneers in the host institution. To develop deeper insight into the learning and knowing, and value created in and by the Groen Sebenza CoP in the Host Institution, I also sought insight into enabling and constraining factors and how these shaped and contributed to empowerment and retention of the pioneers in sustainable green jobs. The research addressed the main question of ‘How do processes of learning, knowing and value creation contribute to empowerment and retention of unemployed youth in a successful Host Institution in the Groen Sebenza programme, and what enabled or constrained the empowerment and retention processes and outcomes?’. Three sub-questions were used in the study, which focussed on the mentoring, training and workplace experiences and how they contribute to the process of learning and knowing within the Groen Sebenza Community of Practice in the Host Institution? [Addressed in Chapter 4], the value creation elements that emerged in the implementation of the programme in support and empowerment of the pioneers in the Host institution’s Groen Sebenza CoP? [Addressed in Chapter 5], and the enabling and constraining factors that shaped and contributed to the uptake of the Pioneers into sustainable green jobs at the Host Institution within the Groen Sebenza Programme? [Addressed in Chapter 6]. The research was conducted as a qualitative case study, in which I used semi-structured interviews as a key data source, as well as document analysis, and a questionnaire. The study drew on inductive, abductive and retroductive modes of inference since I sought to explore an understanding of the practices and learning that occurred that contributed and led to the successful uptake of Pioneers into jobs, as well as the enabling and constraining factors. The study was interpretive at the epistemic level, and had a social realist under-labouring at the ontological level. Key findings of the study point to the development of enabling cultures of mentoring in workplaces, and the provision of a diversity of workplace learning experiences including formal training. It also points to the importance of personal emergent properties amongst mentors and pioneers that embrace a willingness to work together and build strong relationships, and to learn together. Learning in the community of practice was shown to develop identity and a sense of belonging as pioneers were given meaningful tasks to do and their training and interactions with mentors was experienced as meaningful and relevant. The contributions of the pioneers to the institutional mandate was appreciated by the mentors and therefore also well supported within an empowerment orientation. Various structural factors contributed to this enabling situation, most notably strong support from management as well as good co-operation across divisions. Constraining factors included the physical distances in the province, as well as financial and technical issues such as poor ICT communication systems. Overall, though the study showed that a strong approach to learning in communities of practice supported by empowering mentoring can lead to the integration of young pioneers into sustainable green jobs in the environmental sector. A whole institution approach to this process is, however, needed, and the organisation needs to develop a culture of social learning. As recently as September 2020 as this study was being finalised, the Presidential Employment Stimulus Plan (Office of the President, 2020) following the initial economic shocks emanating from the COVID-19 pandemic, made yet another commitment to using the Groen Sebenza model to create and support sustainable job creation for young people in South Africa today in the environmental sector. This study has been developed and designed to understand those processes and enabling conditions that can support retention and empowerment of young people to take up jobs in the environmental sector today. Its recommendations may therefore be of value to those involved in seeking to support sustainable impacts in terms of retention and employment in programmes such as the Groen Sebenza, and in the Groen Sebenza programme itself as it continues to unfold as a key job creation tool for unemployed youth. , Thesis (MEd) -- Faculty of Education, Education, 2021

  • Description: This thesis interrogates the relationship between the Dispute Settlement Understanding and Africa Continental Free Trade Area dispute settlement mechanism, in light of the conflict of jurisdiction. The conflict of jurisdiction is an adverse effect of the fragmentation of international law. The uncoordinated proliferation of international treaties has increased occurrences of overlapping memberships and overlapping subject matter regulation amongst treaties. Whenever the overlaps mentioned above exist, and a dispute arises concerning matters of overlap, that dispute can be heard in more than one tribunal, giving rise to a conflict of jurisdiction. Jurisdictional conflicts are a problem because they breed uncertainty in the adjudication of disputes; they increase the risk of forum shopping, conflict of rulings, protracted litigation, and waste resources. There is a significant risk for jurisdictional conflicts between the World Trade Organisation and Africa Continental Free Trade Area agreements, because of membership and subject matter overlaps. To mitigate the problems caused by jurisdictional conflicts, the Africa Continental Free Trade Area agreement has incorporated a fork-in-the-road clause. Fork-in-the-road provisions allow parties to choose their preferred forum, and once the forum is chosen, the parties are prohibited from bringing the same dispute to another tribunal. Unfortunately, fork-in-the-road clauses are insufficient in resolving jurisdictional conflicts because they do not bind the Dispute Settlement Understanding. It is only bound to enforce World Trade Organisation obligations and not non-World Trade Organisation obligations. The extent to which non-World Trade Organisation norms apply in the Dispute Settlement Understanding is unsettled, making it difficult to conclude whether a fork-in-the-road provision will be effective an effective solution to potential jurisdictional conflicts. In this thesis, the researcher investigates the prospects of the World Trade Organisation applying the AfCFTA fork-in-the-road clause, directly, as a potential solution to the conflict of jurisdiction. In addition, the researcher will also investigate an alternative means of applying the AfCFTA fork-in-the-road provision, indirectly, using the World Trade Organisation procedural good faith provisions. In conclusion, the researcher provides recommendations on how the World Trade Organisation and the AfCFTA agreement can facilitate the application of fork-in-the-road clauses in the Dispute Settlement Understanding to resolve the conflict of jurisdiction. , Thesis (LLM) -- Faculty of Law, Law, 2021

  • Description: Satoshi Nakamoto, the pseudo-identity accredit with the paper that sparked the implementation of Bitcoin, is famously quoted as remarking, electronically of course, that “If you don’t believe it or don’t get it, I don’t have time to try and convince you, sorry” (Tsapis, 2019, p. 1). What is noticeable, 12 years after the famed Satoshi paper that initiated Bitcoin (Nakamoto, 2008), is that blockchain at the very least has staying power and potentially wide application. A lesser known figure Marc Kenisberg, founder of Bitcoin Chaser which is one of the many companies formed around the Bitcoin ecosystem, summarised it well saying “…Blockchain is the tech - Bitcoin is merely the first mainstream manifestation of its potential” (Tsapis, 2019, p. 1). With blockchain still trying to reach its potential and still maturing on its way towards a mainstream technology the main question that arises for security professionals is how do I ensure we do it securely? This research seeks to address that question by proposing a decision-making model that can be used by a security professional to guide them through ensuring appropriate security for blockchain deployments. This research is certainly not the first attempt at discussing the security of the blockchain and will not be the last, as the technology around blockchain and distributed ledger technology is still rapidly evolving. What this research does try to achieve is not to delve into extremely specific areas of blockchain security, or get bogged down in technical details, but to provide a reference framework that aims to cover all the major areas to be considered. The approach followed was to review the literature regarding blockchain and to identify the main security areas to be addressed. It then proposes a decision-making model and tests the model against a fictitious but relevant real-world example. It concludes with learnings from this research. The reader can be the judge, but the model aims to be a practical valuable resource to be used by any security professional, to navigate the security aspects logically and understandably when being involved in a blockchain deployment. In contrast to the Satoshi quote, this research tries to convince the reader and assist him/her in understanding the security choices related to every blockchain deployment. , Thesis (MSc) -- Faculty of Science, Computer Science, 2021

  • Description: Education in South Africa is said to be in crisis in recent years as many learners cannot pass standardised tests at the correct grade level. This has encouraged the South African Government and the Department of Basic Education (DBE) to introduce technology, specifically Tablet PCs, into education to improve learning outcomes in South African government schools. Furthermore, because of the coronavirus pandemic that started in 2020, educators were increasingly expected to find alternative, digital, online methods to continue teaching learners. Thus, the need for remote or distance education suddenly became an important factor in creating a need for online, remote learning. Against this backdrop this study aimed to determine how and in what ways educators could be supported to promote effective use of Tablet PCs both in the classroom and for distance learning. This study used Action Design Research to develop a guide based on both theory and the results gathered from the educator participants at a local secondary government school in Makhanda, South Africa. The finalised guide presents recommendations to educators, principals, and the DBE to promote acceptance and adoption of technology in the classroom and for distance learning. These recommendations include the provision of data, technological training and pedagogical support, a functioning community of practice, an online learning community of practice, and support from the DBE. Other enrichment factors were also recommended. , Thesis (MCom) -- Faculty of Commerce, Information Systems, 2021
