- Description: The research effort developed four possible scenarios for the future of banking in South Africa towards 2055. The scenarios sought to stimulate thought on the possible, probable, plausible and preferred effects of disruptive innovation and regulation in the South African banking sector. The scenarios were developed in strict accordance with the 5 stages, and 9 steps, of the scenario-based planning process of futures studies. A conceptual futures studies model for banking in South Africa was developed to guide and clarify the way in which the research on South African banking can be integrated into the body of existing futures studies theory. The research study began with a comprehensive environmental scan, where various megatrends and driving forces are identified. A PESTEL analysis provided a deeper understanding of the driving forces. A Real-Time Delphi study was conducted in order to validate and prioritise the megatrends and driving forces that emerged. As a result, the research study was able to present four plausible scenarios that provide a better understanding of the future of banking in South Africa over the decades to come. The research presents banking as a complex, multi-faceted sector that is heavily influenced by advances in technology. The Real-Time Delphi research allowed the aggregation of expert knowledge. This is used as a guide to assist decision-makers and industry leaders in the adoption of appropriate business models and strategies towards a preferred future state. The research defined the Integrated Vision as the preferred future state for the South African banking sector towards 2055. The study closes a research gap where current strategies deviate from proposed strategies that drive the achievement of the Integrated Vision by 2055. Finally, contextually aligned practical recommendations are provided to assist decision-makers, industry leaders and change agents to work towards a preferable future state. The proposed recommendations are placed into broad categories of innovation, financial inclusion and collaborative regulatory relationships. The research makes a meaningful contribution to the South African banking sector by introducing a forward-looking, systems-thinking approach to disruptive innovation and regulation in the South African context.

- Description: 3D printing is one of the most disruptive technologies that truly has the potential to change medicine and healthcare by making care affordable, accessible and personalized. It can bring a new era if printers become more sophisticated, printing biomaterials gets safely regulated and the public acquires a common sense about how 3D printing works. An understanding and appreciation of the possible futures of 3D printing technology will be of great value to various stakeholders within the country. This research will identify and describe current drivers that should be appreciated for the government, business communities, academic institutions, healthcare provider’s policy makers and the society at large to make intelligent decisions about the future of 3D printing in medical devices. This study is aimed at identifying the possible futures of 3D printing in orthopaedic devices in South Africa. Causal Layered Analysis (CLA) and the Six Pillars of Futures were identified as the preferred methodologies to be utilised to respond to the research objectives of this study. A detailed literature study was undertaken to evaluate the existing body of knowledge on the research topic. The literature study revealed that several factors needs to be addressed before 3D printing is completely integrated into everyday joint reconstruction surgery. Having already made a big impact in the medical sector, three-dimensional printing (3DP) technology continues to push the boundaries of cost efficiency, convenience, and customization. It has transformed some aspects of medical device production. To date, 3D printing has been employed predominantly by hobbyists, product designers and a few select industrial applications, but the performance of additive manufacturing equipment is quickly evolving, the choice of materials is increasing, and prices of both materials and printers are falling rapidly, all factors through which 3D printing is swiftly progressing to attain wider consumer acceptance and a greater number of manufacturing uses.

- Description: The study aimed at undertaking a comparative investigation of the gendered nature of intra-household decision making in the use of social grants and to ascertain its impact on selected households in Zimbabwe and South Africa as a comparative study. A methodological triangulated approach was used in the study where both quantitative and qualitative approaches were adopted. A total of 250 heads of households were selected as a sample from the study population. Herein, 200 respondents were given the survey questionnaire (100 respondents from Zimbabwe and another 100 from South Africa). A larger number of respondents were sampled for quantitative data in order to improve validity and generalisability of the results. Interview participants for this study were conveniently selected from communities benefiting from cash transfers and social grants. The researcher then interviewed a total of 50 participants (25 from Zimbabwe plus another 25 from South Africa). The samples for the study were arrived at using the multi stage sampling techniques. From these samples two data sets were obtained namely quantitative and qualitative. The study yielded that there are more social grants that are targeted at benefiting older people in Zimbabwe whereas there are a variety of social grants that are aimed at benefiting people from all age groups in South Africa. The study also established that the nature of intrahousehold decision making is determined by the variations of the recipients’ age variations. In Zimbabwe It was revealed that most of the recipients who were younger than 65 years bought basic needs, while in South Africa the recipients mostly used the money for entertainment, savings and clothes. The current economic situations in these two countries determine their spending patterns. Both in Zimbabwe vi and South Africa, recipients older than 65 years used their money to buy agricultural inputs. In both countries most of the beneficiaries were female because there are the primary caregivers and also because of the increased number of female headed households precipitated by high divorce rates. It also emerged in the study that there are many factors that influencethe gendered nature of intra household decision making dynamics such as cultural, available resources, number of dependents. These factors have the potential to either reinforce or offset the impact of social grants. Furthermore, the decision-making roles for men and women in both Zimbabwe and South Africa were determined by income and economic activities, food security and basic needs; marital status, family and social structures. But on the whole, it was revealed in the study that the responsibility of the head of household to provide leadership and make crucial decisions such as using social grants money. In both countries members from outside the nucleus family were also involved in making decisions on behalf of the beneficiaries. Elderly people retained the majority of the decision-making power in most of the households in both Zimbabwe and South Africa. It also emerged that in most households in both countries, decision making on the use of social grant money was arrived at after consultations particularly between spouses. In order to enhance productive decision making and optimise the social grants usefulness, the study recommends that there should be monitoring and evaluation on how the social grants are being used and who is behind the decision-making process. More so, a conceptual framework was also suggested to explain intrahousehold decision dynamics.

- Description: Drug-induced liver injury (DILI) is recognized as a significant clinical problem, which may account for up to 50% of all cases of acute liver failure. DILI is initiated by the bioactivation of parent drug molecules to produce chemically reactive metabolites. These reactive intermediates induce mitochondrial dysfunction and oxidative stress leading to glutathione (GSH) depletion and damage to cellular proteins, lipids and nucleic acids, which eventually culminates in necrotic cell death. The principal objective of this study is to establish an in vitro screening platform to identify potential hepatoprotective natural products (plants and mushrooms) from South Africa (SA). Aqueous plant extracts (Cyclopia intermedia, Opuntia ficus indica and Kigelia africana), and aqueous and ethanolic macrofungal extracts (Ganoderma lucidum, Russula capensis, Pleurotus ostreatus and Lenzites elegans) were prepared and screened against HepG2 and VERO cells to assess their safety using Hoechst 33342-PI dual labelling. A drug-induced hepatotoxic model was established, using the dietary supplement menadione (vitamin K3). Hoechst 33342- PI, -CellROX® Orange and -TMRE dual labelling was used for necrosis, oxidative stress and mitochondrial membrane potential depolarization (ΔΨm) detection, respectively. The accuracy of the hepatoprotection model was confirmed through HepG2 cellbased assays (Hoechst 33342- PI, -CellROX® Orange and -TMRE dual labelling) that measured the protective effects of natural products against the menadione-induced toxicity, anti-oxidant assays (DPPH, NO, ORAC, CAPe and FRAP) that measured their anti-oxidant potential and enzyme assays (βglucuronidase, carboxylesterase and CYP450 isoform 3A4) that measured their effects on drug metabolism. Silymarin was used as a positive control for each assay. Menadione displayed significant cell death, increased oxidative stress and decreased ΔΨm at an elevated concentration of 100 μM; confirming the hepatotoxicity model, where necroptosis was suspected to be menadione’s cell death mode. Only ethanolic G. lucidum was cytotoxic. All three aqueous plant extracts demonstrated strong anti-oxidant capacities out of all the tested extracts; where C. intermedia displayed the most promising DPPH, NO, ORAC, CAPe and FRAP activity, followed by aqueous G. lucidum. Aqueous plant and ethanolic macrofungal extracts (C. intermedia, O. ficus indica, K. africana, and ethanolic P. ostreatus, R. capensis) displayed decreased menadione-induced ROS production and protected against menadione-induced ΔΨm depolarization, posing them and aqueous G. lucidum potential therapeutic interventions for DILI. Ethanolic L. elegans demonstrated the highest enzyme inhibition for each assay and presented genotoxicity, ruling it out as a therapeutic strategy against DILI. Together these assays addressed several aspects relating to DILI and hepatoprotection, and served as a good starting point in evaluating the therapeutic value of natural products from South Africa.

- Description: Handicrafts made in Kenya are popular with tourists and provides income to many artists. One such artist is Joseph Morris Njau Mung’othi, who renamed himself Morris ‘Foit’ out of respect for a Czech professor, Francis Foit who mentored him. The use of natural materials [non-timber forest products (NTFP)] for making handicrafts is common, but what is less common is the use of dead wood for making sculptures. This is a case study of a Kenyan sculptor who uses deadwood for carving, and has risen out of poverty by selling his art. He educated his five children and accumulated assets including a two-storeyed house-cum-studio and a car. Furthermore, his art gave him opportunities to travel to Uganda, Botswana and the United States. He is also the founder of an art center in Nairobi called the Kuona Trust, which supports local artists to exhibit and sell their work. This case study clearly demonstrates how the use of a NTFP product (in this case deadwood) helped Foit’s family rise above poverty.

- Description: Hypolithic habitats are important for the persistence of fauna that utilize these habitats as refuges and resource patches. Little is known, however, about the composition and structure of this community in the semi-arid Karoo. The current study therefore aims to explore the patterns and processes behind hypolithic communities, through determining the effect of rock size and baboon presence on the hypolithic community, the influence of rock size on the microclimate experienced under rocks, as well as determining the short- (over five days) and long- (over 12 months) term colonisation of the hypolithic habitat following a rock rolling disturbance, in a semi-arid Karoo environment. The hypolithic fauna encountered, and the temperature and moisture content experienced under a range of rock sizes were measured. Additionally, hypolithic fauna under rocks that were rolled to mimic rock rolling by baboons were sampled after a set period (i.e. over five days and 12 months). Large rocks were found to provide a more stable microclimate than small rocks. The probability of hypolithic fauna presence was influenced by rock size and season, and hypolithic fauna abundance (except in the dry season), richness, body size and biomass did not correlate with rock size. Additionally, the probability of detecting hypolithic fauna under intermediate sized and larger rocks was greater in the presence of baboons than in the absence of baboons, and in the presence of baboons hypolithic fauna richness increased with rock size. Furthermore, it was shown that hypolithic fauna abundance and biomass did not differ under rolled rocks over a short- (i.e. over five days) or long- (i.e. over 12 months) term period. The short-term colonisation of hypolithic habitats was not influenced by season or rock density. Lastly, most of the change in hypolithic community composition (over 12 months) occurred in the first three months and thereafter the hypolithic community composition approached pre-disturbance levels in month 12. The hypolithic habitat was shown to be influenced by a variety of conditions and processes affecting hypolithic community composition and structure. This study therefore contributes to our understanding of the hypolithic invertebrate community in the eastern Karoo, and the influence of rock size, baboon presence, microclimate and colonisation on hypolithic community composition and structure.

- Description: Hypolithic habitats are important for the persistence of fauna that utilize these habitats as refuges and resource patches. Little is known, however, about the composition and structure of this community in the semi-arid Karoo. The current study therefore aims to explore the patterns and processes behind hypolithic communities, through determining the effect of rock size and baboon presence on the hypolithic community, the influence of rock size on the microclimate experienced under rocks, as well as determining the short- (over five days) and long- (over 12 months) term colonisation of the hypolithic habitat following a rock rolling disturbance, in a semi-arid Karoo environment. The hypolithic fauna encountered, and the temperature and moisture content experienced under a range of rock sizes were measured. Additionally, hypolithic fauna under rocks that were rolled to mimic rock rolling by baboons were sampled after a set period (i.e. over five days and 12 months). Large rocks were found to provide a more stable microclimate than small rocks. The probability of hypolithic fauna presence was influenced by rock size and season, and hypolithic fauna abundance (except in the dry season), richness, body size and biomass did not correlate with rock size. Additionally, the probability of detecting hypolithic fauna under intermediate sized and larger rocks was greater in the presence of baboons than in the absence of baboons, and in the presence of baboons hypolithic fauna richness increased with rock size. Furthermore, it was shown that hypolithic fauna abundance and biomass did not differ under rolled rocks over a short- (i.e. over five days) or long- (i.e. over 12 months) term period.

- Description: The study examined the relationship between capital structure and bank performance in South Africa using five small banks and the two big banks from 2002-2017. Fixed effects model, Pooled and the random effects model were utilised to test the relationship between capital structure and bank performance. Return on assets and the earnings per share were used as a measure for financial performance while the debt to equity ratio and the debt to assets ratio were used as proxies for capital structure. The results show that there is a negative significant relationship between return on assets and the two capital structure measures meaning that higher leverage ratios lead to lower profits measured by return on assets. while there is a negative significant relationship between earnings per share and the capital structure meaning that higher leverage ratios lead to lower profits. The study recommends that financial managers of banks should maintain lower debt than equity in their mix of capital structure as more debts is not good for the performance of banks.

- Description: Trade unions play an important role in the South African labour relations. Power relations in the workplace favour the employers in terms of decision-making due to the resources that employers have at their disposal, as compared to single employees. In order for employees to be at par with employers during collective bargaining, they join or form trade unions. In South Africa for example, the apartheid government was against trade unions as they were viewed as a threat to the hegemony of the apartheid regime. The democratic dispensation that was ushered in, 1994, sought to change that through a tripartite arrangement between employees, employers and the government. This was done to ensure that trade unions become part of the decision making process on workplace related matters. The South African Constitution of 1996 states that every employee has the right to form and join a trade union and participate in the activities and programmes of a trade union. Trade unions are also able to influence policy related decisions as they participate in decision-making bodies like the National Economic Development and Labour Council (NEDLAC) and the International Labour Organisation (ILO). Government has enacted legislation that gives effect to the rights that are enshrined in the Constitution. Through protection afforded by legislation, trade unions are able to recruit members in different sectors and with sufficient sector representation are able to form sector specific Bargaining Councils with Employers’ Organisations representing such sectors, that are able to negotiate terms and conditions of employment for employees in that sector. This study considers and evaluates the rights conferred to trade unions by the Constitution and legislation. The study focuses on the impact of dwindling trade union membership numbers on collective bargaining in South Africa and makes a brief comparison with the European Union (EU). It examines the history of trade unions and the causes of the reduction of trade union membership numbers in South Africa and the EU. Case law is considered in order to gain an understanding of the changing collective bargaining landscape in South Africa. Consideration is given to some of the challenges faced by trade unions in seeking new members and this study makes recommendations of measures that could be put in place to assist trade unions increase their presence in the workplace.

- Description: African elephants (Loxodonta africana) were absent from large portions of the Eastern Cape Province of South Africa for more than 100 years following widespread hunting for ivory. However, recent shifts in land use practices have resulted in the establishment of many private game reserves throughout the region. Some of these reserves have reintroduced elephants, raising management concerns because of the perceived impact that elephants can have on vegetation and the animals that rely on it for resources. My thesis aimed to assess the role of elephants in determining the structure and complexity of the locally important Thicket Biome and how medium and large mammals are affected. I quantified the woody and succulent components of Albany Thicket across nine reserves with elephants between May 2016 and November 2017 using a modified Point-Centre-Quarter method. Camera traps were deployed at each site for the duration of a calendar year to measure the relative abundances of all medium and large mammals at the sites. Across all study sites, climatic conditions (specifically rainfall and temperature) were the primary drivers of woody vegetation structure and diversity. Elephants appeared to have little influence since they were reintroduced at low densities 20 years ago. The associated mammal communities were mostly influenced by the height and basal area coverage of the thicket across the sites. I conclude that because elephant populations have been maintained at relatively low densities across my study sites, negative effects on the thicket vegetation and the associated mammal communities were not observed. In fact, the establishment of private game reserves, even with elephants, present may offer sustainable conservation for the threatened Albany Thicket. However, these elephant populations are still relatively new and changes to the vegetation are likely to be cumulative. Thus, future research should focus on how the vegetation is affected over time. To this end, I recommend the establishment of permanent sampling stations across all reserves with elephants in the Eastern Cape Province.

- Description: This study provides an analysis of financial and growth dynamics with a view to assess the impact of financial development on economic growth in Ghana. The study also examines the extent to which financial developments in Ghana are affecting capital accumulation and industrial sector growth. The analysis was performed by examining the financial development indicators and economic growth data for Ghana over the period from 1965 to 2016. The study was motivated by the theoretical indications that improvements in financial intermediation within the economy can induce growth of the real sector and thus lead to economic growth. There have been notable structural and financial sector reforms in Ghana since the early and late 1980s. The indications in the financial sector portray improvement in the measures of financial development in the post-reform era as compared to the years before. The findings of the study complement existing research findings and information on finance-growth association as well as the influence that finance has on the sources of growth. The study adopted real per capita gross domestic product (GDP) as a measure of economic growth. In addition, three real sector indicators serving as the sources of growth, included; capital accumulation, industrial value-added and manufacturing value added. The analysis also adopts four financial indicators, expressed as percentage shares of GDP, namely; domestic credit to private sector, total domestic credit provided by financial sector, broad money supply and financial sector deposits—as measures of financial development. The analysis of the impact of the financial development on capital accumulation, industrial output growth, manufacturing productivity and economic growth were estimated using the linear regression estimation techniques within the GMM estimation approach. The study, additionally, examined the short-run and long-run impacts of financial development on economic growth indicators by employing the Vector Autoregressive Regression (VAR) within the Autoregressive Distributed Lag (ARDL) approach. The study further assesses the direction of causality between financial development and economic growth indicators using the cointegration and Engle-Granger causality testing approach within VAR models. The Bayesian Vector Auto Regression (BVAR) models were applied to examine the drivers of economic growth and to assess the sensitivity of economic growth to financial development and macro-economic shocks. This assessment was carried out to examine the maximising behaviour of financial development and to find out if there exists threshold point beyond which finance adversely affects economic growth in Ghana. The results showed that credit to private sector shows a strong positive persistence in promoting economic growth in Ghana. The results show that financial development dynamics in Ghana positively affect long run economic growth and further indicate that the rate of impact was relatively higher in the post reform period of 1984 to 2016. The study further found a bi-directional causal association between financial development and economic growth. Regarding the sources of growth, the study found that financial development strongly contributes positively to capital accumulation in the long-term, however, the findings further suggested that, to some extent, the growing size of finance dampens capital formation and economic growth. This suggested the existence of inefficiencies in the expanding size of total credit offered by the financial system in Ghana. The study further found a long-run positive association between financial development and industrial productivity (except for manufacturing) growth in Ghana, with industry growth substantially determined by private credit. The results of the assessment on the sensitivity of economic growth to shocks in financial development indicators show that Ghana ‘s economic growth is, to a larger extent, influenced by domestic credit provided to the private sector. Also, the results showed that economic growth has been highly responsive to macro-economic shocks such as government expenditure and industrial sector growth although industrial growth seems to show a strong negative persistence on Ghana ‘s economy. The results from the analysis of finance and economic growth shows that existence of different optimal growth maximising points domestic credit, broad money, financial sector deposits and the overall financial development ratios as depicted by the various inverted U-shaped relationship between the financial development indicators and economic growth. The optimal size or maximising positions or thresholds for private credit and total credit were found to be at approximately 20.0 per cent and 28.0 per cent of GDP, respectively. On the other hand, the optimal size or minimum positions or thresholds for broad money supply and total financial sector deposits were found to be at approximately 19.0 per cent and 10.0 per cent of GDP, respectively. With regards to broad money supply-to-GDP and financial sector deposit-to-GDP ratios, the respective averages of 23.19 per cent and 13.77 per cent for the period 1965-2015 are higher than the minimum required thresholds of 19.00 per cent and 10.00 per cent, respectively. The findings show that financial developments have a strong positive association with economic growth, but the results also give the indication that although financial development can enhance growth and inefficiencies in the financial system can equally dampen growth at some levels. overall, the study found that financial reforms have positively contributed to economic growth in Ghana and the impacts of financial development on economic growth in Ghana have been higher in the post-reform era. The effect of financial reforms on capital accumulation was not significant although the study established that the impact of structural reforms was strong and adversely affected capital accumulation in Ghana. With regards to the industrial productivity growth, the study found a positive association between financial development and industry growth in Ghana. It was, however, observed that financial reforms have fails to significantly affect growth of industrial productivity and the impact of financial development on industry sector growth in Ghana are low but the sector experienced relatively higher growth in the pre-reform era.

- Description: Modern day organisations compete in an ever growing and highly competitive global environment. International competitiveness continues to play a critical role in ensuring that both organisations and employees grow and succeed. An organisation’s and employee’s ability to innovate remains one of the key factors in ensuring that they remain competitive and relevant amongst global organisations. Globalisation, access to advanced technology and the enhanced ability to travel has further enabled consumers and to keep up to date with international trends. These phenomena’s make it increasingly and ever important to remain relevant and innovate to attract new customers or consumers and to retain the current ones. The term job embeddedness relates to the relationships employees have between the organisation they work for and the community they form part of. It is felt that a link may exist between job embeddedness and employees engagement in innovative work behaviours to ensure that employees continuously generate new and improved processes, ideas, technologies to contribute to the organisations success. It is against this setting that an empirical study was created for the purpose of concluding evidential data needed to draw conclusions and make recommendations to leadership within organisation’s relating to the impact that job embeddedness has on engagement in innovative work behaviours. Furthermore, the impact of job embeddedness is tested against employee’s engagement in innovative work behaviours. 90 professional part-time executive MBA programme individuals who were enrolled at the Nelson Mandela University Business School in South Africa and who are based at the four major centres of the Business School, which included Port Elizabeth, Cape Town, Durban and Johannesburg were approached to take part in this study. These individuals were employed in a variety of spheres in industry, including engineering, financial services, information technology, accounting and management in organisations that spanned a multitude of additional industries. As a result of these individuals participation, 549 participants took part in the survey. Key findings of the study includes that employee fit into the organisation, employee fit into the community and employee perceived sacrifice in the event of leaving the organisation are all significantly related to engagement in innovative work behaviours. A key recommendation of the study would be that in order to increase the organisational aspect of job embeddedness, organisational leaders would need to consider ways to or place emphasis on factors that would promote organisational fit and organisational sacrifice.

Furthermore, the impact of job embeddedness is tested against employee’s engagement in innovative work behaviours. 90 professional part-time executive MBA programme individuals who were enrolled at the Nelson Mandela University Business School in South Africa and who are based at the four major centres of the Business School, which included Port Elizabeth, Cape Town, Durban and Johannesburg were approached to take part in this study. These individuals were employed in a variety of spheres in industry, including engineering, financial services, information technology, accounting and management in organisations that spanned a multitude of additional industries. As a result of these individuals participation, 549 participants took part in the survey. Key findings of the study includes that employee fit into the organisation, employee fit into the community and employee perceived sacrifice in the event of leaving the organisation are all significantly related to engagement in innovative work behaviours. A key recommendation of the study would be that in order to increase the organisational aspect of job embeddedness, organisational leaders would need to consider ways to or place emphasis on factors that would promote organisational fit and organisational sacrifice.

- Description: Land reform in South Africa, which is comprised of land redistribution, land tenure reform, and land restitution, continues to be an emotive subject and has largely racially polarised South Africa. The slow pace of land reform, expropriation, the amount of land to be returned to black people, debates around the role of the Constitution in land reform, the market-based approach and the perceived negative attitude of white farmers have dominated the debates on land reform. There is, therefore, a huge chorus on the struggles for land acquisition and less on what happens when people are given land. A few studies on post-settlement livelihoods experience have managed to close this gap slightly in the literature by showing that land reform has contributed little or no material and livelihood benefits to beneficiaries and that many farms are lying idle after land reform, especially land restitution, projects. These studies on post-settlement livelihoods experiences of land reform beneficiaries have not managed to capture fully the “voices” of beneficiaries on land and livelihoods. This dissertation seeks to provide a sociological documentation of the post-settlement livelihood experiences of land restitution beneficiaries. It does this by primarily tracing the ability and/or the inability of land restitution beneficiaries of Macleantown, about 40 kilometres northwest of East London, in the Eastern Cape to reconstruct livelihoods after resettlement, bearing in mind that these land restitution beneficiaries have been resettled twice, during forced removals in the 1970s and after land restitution, post-1994. Therefore, the study engages with questions of whether or in what ways land compensated restitution beneficiaries have managed to reconstruct livelihoods after land transfer. To capture the livelihood experiences of land restitution beneficiaries fully, I also studied the Salem restitution case, which is 20km away from Grahamstown in the Eastern Cape. Because land restitution involves resettlement, I decided to use two resettlement theories, namely Thayer Scudder’s four stages model and Michael Cernea’s Impoverishment Risks and Reconstruction (IRR), to understand risks associated with resettlement. Additionally, since this dissertation seeks to understand and document livelihood reconstruction and poverty reduction within the context of restitution resettlement, I also utilised the Sustainable Livelihoods approach and Amartya Sen’s capabilities approach. This thesis is based on multiple research methods that include documentary study, focus group discussions, conversations, archival research, in-depth interviews, transect walks, participant observation and life histories. My findings show that land transfer under the land restitution programme has largely not enabled land beneficiaries in Macleantown and Salem to reconstruct land-based livelihoods after settlement. I also established that land restitution beneficiaries face risks that are identified by resettlement theorists such as lack of proper planning, resettling trauma, struggles in community reconstruction and poverty. Beneficiaries have not managed to reap any meaningful benefits from the land, meaning that restitution has not led to self-sufficiency for these beneficiaries because all land beneficiaries are heavily dependent on social grants. However, one needs to emphasize that land restitution has restored the dignity of beneficiaries because beneficiaries have accessed their forefathers’ land that they fought for. This is because beneficiaries believed that it was their duty to fight for their land on behalf of their ancestors. I reach the conclusion that the whole idea that restitution claimants who are scattered all over can be grouped into a Community Property Association (CPA) and farm collectively as a ‘community’ to improve livelihoods is a misleading romanticisation of the envisaged outcomes of the land restitution project. Time has passed after land dispossession and land claimants are different human beings to what they were before land dispossession, i.e. far from the agrarian society they were before land dispossession. Group dynamics, lack of adequate post-settlement support (PSS), land reform designs, lack of commercial agricultural skills, as well as entitlement syndrome, old age of beneficiaries, infighting and marginality of agricultural business has made it nearly impossible for restitution beneficiaries to reconstruct land-based livelihoods. Additionally, the government appears to be more interested in ‘correcting apartheid’ rather than creating viable farms. It is important to state that this thesis does not advocate for the erasure of the restitution programme or to belittle land beneficiaries but argues for the rethinking of the restitution model in the context of massive failures, as well as coming up with a new and flexible model of land restitution that will meet the modern needs of beneficiaries. This thesis contributes to an understanding of the risks and the challenges of livelihoods reconstruction faced by resettling communities through an investigation into the post-settlement livelihoods experiences of land restitution beneficiaries through ‘thick descriptions’.

- Description: Ethical leaders consistently set ethical principles within the institution and act in accordance with them; hence, leaders should be a key source of ethical guidance for employees. As the business world is constantly evolving, leaders increasingly are required to ethically lead across different sectors. Current literature on ethical leadership and its influence of employees reflects mostly a Western, European and Asian-based private-sector perspective, pointing toward a compliance-oriented understanding of ethical and unethical leadership. This study examined how perceived ethical orientation of a leader has an impact on employees’ predisposition to behave ethically within a South African context. Qualitative data was collected as the study adopted the interpretivist paradigm, which made it easier for participants to use descriptive words and qualifying statements to express the level of influence their leaders had on their ethical orientation. The target population of the study included all staff of the institution; and participants were chosen using the purposive sampling method. Data was collected from 12 employees using semi-structure interviews. Thereafter, thematic analysis was used to identify and organise participants’ experiences into themes that established the basis for the study findings. These findings confirmed that perceived leader ethical orientation has an impact on employees’ predisposition to behave ethically. The study found that ethical leaders had a track record of being consistent, honest, trustworthy, truthful and credible, and being a role model. In addition, the study also found that unethical leaders are easily identifiable by their perpetual inability to uphold principles of integrity, reliability, rationality, and social justice and fairness. The researcher concluded that the moral identity of the leader has an influence on followers’ predisposition to behave ethically or unethically. The implications of this study are that ethical morals, by their very nature, are transferable from one person to the other and ethical leadership was one antecedent through which this transfer takes place. However, ethical leadership was not the only apparatus that influenced employees’ ethical predisposition and these afford opportunities for future research.

- Description: The practice of Development-Induced Displacement and Resettlement (DIDR), historically, has often led to negative consequences for those affected by development projects, including but not limited to, the construction of large dams. Although DIDR arises from the need to provide goods and services that characterise development, it often leaves those who are forced to give up their assets, resources, and long standing social networks in dire socio-economic conditions as a result of resettlement. In many such cases, the provision for losses suffered by those primarily affected is often insufficient, leading to further losses experienced as a result of the complete life change experienced by those affected by resettlement. Research has shown that the insufficiency of such provisions for losses is attributable to not only the value of the provision itself, but also the manner in which resettlement processes are implemented. While early on, researchers believed that the development of policies would have a significant, positive impact on the practice of resettlement and its outcomes, evidence would later show that the development of policies alone is not a panacea for all challenges associated with forced resettlement. Further research revealed that resettlement is characterised by inherent and active complexities which are often at play, and may impede effective implementation. Hence, while the development of policies is essential, both the development and implementation of policies must be undertaken in a manner that seeks to actively address the inherent complexities of resettlement. This thesis aims to explore the implementation of resettlement policies in two case studies, where in one case, resettlement was informed by national policy, and in the other, by policies developed by a parastatal tasked with the responsibility of executing resettlement. The study makes a comparative analysis between the two cases, and explores the factors at play in the implementation of resettlement policies – whether such factors serve to facilitate or impede effective implementation – as well as the nature of the outcomes on the ground. As an overarching goal, the research aims to provide a basis upon which a framework for the development of a national level policy of resettlement may be developed. In this regard, the thesis undertakes a comparison of the Indian resettlement case with the Lesotho case. The former, in addition to having developed a resettlement policy at the national level, has a long history of experience in forced resettlement and displacement, from which invaluable lessons have been learned. The latter, on the other hand, has no resettlement policy at the national level, although the country has also experienced forced resettlement dating back to nearly three decades ago. Although India and Lesotho have distinct social, cultural, economic and demographic characteristics, research has shown that the complexities of forced resettlement, and their outcomes on affected people, are largely applicable across the different contexts. Hence, certain dimensions and lessons can be transferable from the Indian case to the Lesotho case, and vice versa. However, for the purpose of this thesis, the focus is on providing a basis for national policy development in Lesotho, in light of Indian policies and practice. The empirical basis of the thesis is an ethnographic study undertaken in relation to the Chandil Dam resettlement case in Jharkhand, India and the Mohale Dam resettlement case in Maseru, Lesotho. The thesis engaged both qualitative and quantitative research methods, as well as four, complementary theoretical tools that analyse the effects of forced resettlement on affected people. The thesis reveals that the negative consequences of forced resettlement resulting from its inherent complexities continue to manifest with concerning effects on the lives of those affected. It shows that the implementation of policies is a complex process that requires collaborative effort from a wide range of stakeholders in a given context. National policies of resettlement are, thus, instrumental in this regard, as they can create an enabling environment for the facilitation of collaborative efforts towards sustainable livelihood re-establishment for those who involuntarily suffer losses to resettlement.

- Description: Health holds an important position in maintainable economic development since it is both a prerequisite for and an outcome of economic development. This means that health contributes hugely to the attainment of sustainable development and health outcomes. The importance of health is demonstrated in the Millennium Development Goals (MDGs) where three of the eight goals are aimed at improving health outcomes. Despite progress made by other middle-income countries in achieving health-related MDGs, South Africa still has worse health outcomes and experiences a challenge in attaining positive outcomes for these goals (Coovadia et al., 2009; Malaudzi 2016). This study’s main focus was to identify the association between public health expenditure and health outcomes in South Africa’s nine provinces from 2002 to 2016. The study implemented fixed effects and a random effects panel data estimation technique to control for time effects and individual province heterogeneity. This was followed by employing the Hausman specification test to identify the fixed effects model as the appropriate estimator for the study. The study also employed the seemingly unrelated regression (SUR) model and the least squares dummy variable (LSDV) model to examine the impact of public health expenditure on each province separately. The findings from the study elucidated that the relationship between public health expenditure and health outcomes in South Africa varied across provinces depending provincial management and infrastructure availability.

- Description: The study sought to investigate the impact of public libraries in developing information literacy in libraries in the Eastern Cape Province of South Africa: a case study of Buffalo City Municipality public libraries in King William’s Town. The objectives of the study were to find out how these three libraries in Buffalo City Metro public libraries ensure equity of library and information services provision to the user communities, to find out how public libraries support education and lifelong learning, to identify the challenges that public libraries face in rendering library and information services with reference to the three libraries, and to investigate the role of library professionals in marketing the library services to the community. Both quantitative and qualitative research methodologies were employed in a descriptive survey. The main research instrument was a questionnaire supported by face to face interviews. A total of 297 questionnaires were distributed and 200 were returned giving a response rate of 67.3%. The quantitative data which was collected through questionnaire was presented using graphs and tables, while qualitative was analysed manually by content analysis, using the notes that were taken by the researcher from the respondents during the interview sessions and reported verbatim in some instances. The findings showed that regardless of South African LIS environment having contradictions resulting from years of apartheid, most of the Buffalo City Metro public library patrons indicated that they experienced fair and equitable access to library and information services. In addition to participants’ quantitative responses, the qualitative excerpts from librarians attested to the library having a classification system that allows easy access to library resources. In addition, findings of the study also revealed that the Buffalo City Metro public libraries have a diversity of users, ranging from different age groups and social standing. The results from the current study revealed that the Buffalo City metropolitan public library users have little knowledge about literacy programmes that are taking place in the library. The findings also indicated that the Buffalo City Metro public libraries market library services by word of mouth, posters and notice boards. One of the major findings of the study is that Buffalo City Metro public libraries are faced with financial constraints and that led to a myriad of challenges ranging from inadequate library operating hours; limited information sources; lack of information retrieval training to patrons; internet connectivity issues; xii lack of professional staff and lack of training on the latest technological trends. The study concludes that the Buffalo City Metro public libraries should establish a marketing strategy to motivate for funding. The study recommended that the Buffalo City public libraries should create an integrated system for all libraries in the metromunicipality that encourages adult literacy programme to raise awareness of information literacy.

- Description: This study seeks to assess the effect of public spending on economic growth, employment, and poverty reduction. The co-existence of a sound fiscal policy and a substantial government expenditure but insignificant returns in terms of social development suggests the potential of a dilemma that needs to be investigated, and to reflect on the dynamics of selected marginalised groups of people and marginalised areas. Hence, the “social inclusion” strategy of the RDP in 1994, and the “inclusive economy” strategy of the NDP in 2014 were implemented with one single objective in mind, that is to narrow the gaps associated with the legacy of apartheid. Despite the implantation of government plans like the RDP and recently the NDP, and regardless of the effective use of fiscal policy, low growth has continued during the post-recession era; unemployment and inequality have persistently remained at high levels. This paradox has led to controversies around fiscal policy’s dual role of stimulating economic growth and income redistribution. To achieve the research objective, the study employs four types of empirical techniques: the nonlinear autoregressive distributive lag (N-ARDL) cointegration model; the economy-wide Leontief approach calibrated on the supply and use tables (dynamic SUT model); a partial general equilibrium approach based on the Social Accounting Matrix (SAM model) used for micro-simulations; and lastly a contemporaneous dynamic computable general equilibrium (CGE) model to assess the effect of fiscal policy on macroeconomic and socioeconomic variables. The study found that during the post-recession era, expansionary fiscal policy had a positive but minute effect on growth, employment and poverty reduction. The effect of government spending has had a minimal effect on historically marginalised groups of people and marginalised areas. This is why a tortoise pace in reducing poverty and inequality has persisted. So, the study recommends that governments should follow a priorities-based government spending policy which fits well with the current situation of the country. Moreover, South Africa needs to adopt international standards and best practices of “science-based strategic” rather than that of “evidence-based strategy” and ensure that only programmes that have proved to be effective be financed in the fiscal budget.

- Description: This study seeks to assess the effect of public spending on economic growth, employment, and poverty reduction. The co-existence of a sound fiscal policy and a substantial government expenditure but insignificant returns in terms of social development suggests the potential of a dilemma that needs to be investigated, and to reflect on the dynamics of selected marginalised groups of people and marginalised areas. Hence, the “social inclusion” strategy of the RDP in 1994, and the “inclusive economy” strategy of the NDP in 2014 were implemented with one single objective in mind, that is to narrow the gaps associated with the legacy of apartheid. Despite the implantation of government plans like the RDP and recently the NDP, and regardless of the effective use of fiscal policy, low growth has continued during the post-recession era; unemployment and inequality have persistently remained at high levels. This paradox has led to controversies around fiscal policy’s dual role of stimulating economic growth and income redistribution. To achieve the research objective, the study employs four types of empirical techniques: the nonlinear autoregressive distributive lag (N-ARDL) cointegration model; the economy-wide Leontief approach calibrated on the supply and use tables (dynamic SUT model); a partial general equilibrium approach based on the Social Accounting Matrix (SAM model) used for micro-simulations; and lastly a contemporaneous dynamic computable general equilibrium (CGE) model to assess the effect of fiscal policy on macroeconomic and socioeconomic variables. The study found that during the post-recession era, expansionary fiscal policy had a positive but minute effect on growth, employment and poverty reduction. The effect of government spending has had a minimal effect on historically marginalised groups of people and marginalised areas. This is why a tortoise pace in reducing poverty and inequality has persisted. So, the study recommends that governments should follow a priorities-based government spending policy which fits well with the current situation of the country. Moreover, South Africa needs to adopt international standards and best practices of “science-based strategic” rather than that of “evidence-based strategy” and ensure that only programmes that have proved to be effective be financed in the fiscal budget.

- Description: Commercial forestry plantations in South Africa play an important role in the economy of the country, contributing 1.2% towards the gross domestic product, as well as with job creation in rural communities. Currently plantation forests occupy 1.1% (1.2 million hectares) of the South African land surface, of which 75 000 hectares are re-established each year. Eucalypts are the preferred species in the commercial forestry industry as they have the ability to grow fast. In addition, desirable characteristics from different eucalypt species can be combined to develop hybrids that can be used to further improve productivity. In South Africa, eucalypt plantations are mostly found in the warm temperate and sub-tropical zones situated in the KwaZulu-Natal and Mpumalanga Provinces. Various strategies are used to increase productivity and maximise site occupancy, including genetic tree improvement, site-species matching, optimising stand densities, management for risk (abiotic and biotic), as well as improved silviculture. Intensive silviculture is practiced by forest companies to maximise initial tree survival and reduce the time to canopy closure. This includes practices such as site preparation, slash management, tree protection, pruning and thinning, fertilisation and vegetation management treatments. Of the silvicultural aspects that are important during re-establishment, pitting, plant quality (plant size) and watering techniques/regimes have all been shown to influence short-term stand productivity. Despite research carried out on these individual components, recommendations as to best operating practices are varied and have changed over the years, with the application of these practices also varying across companies. Furthermore, there is limited published information related to the interaction between these practices, as well as any longer-term impacts of these factors on stand productivity. The objective of the present study was to gain an understanding of the impacts of pitting, plant quality (plant size), planting depth and watering on tree survival, growth and uniformity in South African Eucalyptus plantations. The study was carried out using three separate field trial series. In a first experiment, two field trials compared post-establishment performance of eucalypts planted using various pitting methods. The two trials were planted using Eucalyptus grandis and E. grandis x E. nitens on two contrasting sites, one at Greenhill in the KwaZulu-Natal Midlands and one at Vroegeveld in Mpumalanga. Four manual (notch, agricultural hoe, mattock, road pick) and three motor-manual heads (inverted A, Archimedes screw and Mondi-designed pitting head) were used to prepare and determine the effect of pit size/quality on tree survival, growth and uniformity. The notch pit implement created the smallest pit (1 L volume) compared to the other pitting implements (4 – 6 L volumes). For both trials, pitting method did not have a significant impact on the success of re-establishment or longer-term tree performance (6 yrs 7 mos at Greenhill and 3 yrs 7 mos at Vroegeveld). This indicates that for the sites and the species tested, all pitting implements could be considered viable alternatives. Other factors, such as operational costs, efficiency and ergonomics should be considered when selecting appropriate pitting methods together with tree performance. In a second experiment, three field trials were implemented to test three main factors: plant size (small and large); planting depth (standard and deep); and watering (dry and water planting). The eight treatments (2 x 2 x 2 factorial) were replicated four times and laid out in a randomised complete blocks design. The trials were established across a range of site types (Mt Home in Kwazulu-Natal, Vroegeveld in Mpumalanga and Trust in Zululand) in the summer rainfall region of South Africa using various eucalypt genera (E. dunnii, E. grandis x E. nitens and E. grandis x E. urophylla). Tree performance was assessed, with results up to four, six and seven years presented for the different sites. Results show that planting larger plants had the highest overall survival (x̄ = 81%) compared to smaller plants (x̄ = 58%), which also resulted in improved basal area and volume across all sites. Larger plants were able to tolerate a wider range of site conditions, thus providing an advantage for re-establishment. The cost-to-benefit of this however needs to be assessed, particularly in the context of current operational nursery standards. The benefits of deeper planting and applying water at planting are less clear, but appear to be beneficial under water stress conditions, such as on sandy sites when the weather is hot and dry. A third experiment tested the interaction between different methods of pit preparation (manual versus motor-manual), dry versus water planting, and re-watering at periodic intervals. The experiment consisted of one field trial established with E. dunnii in Greytown, KwaZulu-Natal. Twelve treatments (2 x 6 factorial) were replicated four times and laid out in a split-plot design, with the main factor of watering regime forming the whole plots, and pitting method the sub-plots. Differences in pit size, pit quality and tree performance were assessed. Pit dimensions and soil friability for the two pitting treatments were different, but pit volumes were similar (manually prepared pits = 4.7 L; motor-manually prepared pits = 4.4 L). Differences in pit soil moisture content were detected between dry planting (4.1%) and all other treatments (9.9%). Rainfall occurred in week 1 - 4 after planting (55.2 mm). Subsequently re-watering, relative to watering only at planting, was not beneficial. No significant growth differences occurred between the two pitting methods, nor was there any interaction between the main factors (pitting methods x watering regimes). Survival for dry planting (75%) was significantly lower than all the other treatments (92%), with a weakly significant difference in Biomass index (corrected) (BIc) at one year. Different pit qualities, determined by pitting method, will not significantly affect early eucalypt performance. However, the addition of water or hydrogel (as opposed to dry planting) will improve early eucalypt survival and growth. Eucalypt survival, growth and uniformity in South Africa continue to be impacted by an increase in mechanisation, changing climate conditions and the use of unskilled labour. It is therefore necessary to implement silvicultural practices which improve survival, growth and uniformity. Planting seedlings into good quality pits (regardless of pitting method) with water has shown to improve survival. It is also beneficial in terms of survival to plant larger (prime) plants at a deeper depth especially on sites with drought conditions. Despite all the establishment trials which have been implemented under controlled conditions, high mortality is still experienced and could be due to the lack of knowledge on the effects of plant quality and handling on post planting performance (particularly survival). In future, plant quality and handling in combination with various planting densities and the application of plant stress relievers should be considered to improve survival..
