- Description: Organisations and people find themselves in the era of what is known as the Fourth Industrial Revolution (4IR). Unlike the preceding revolutions, this revolution is characterised by technological advancements that lead to disruptive phenomena. These advancements are growing at an exponential rate. They have brought disruptive innovations that have either reshaped many industries, causing them to lose market share or exit altogether. Some organisations are keen to embrace disruptive innovation to ensure that they are sustainable into the future, while others are only inclined to use known technologies to leverage economies of scale. The 4IR has already been around for a while and is moving at a fast pace. The level of readiness for the automotive assembler, Isuzu Motors South Africa (IMSAf), to take advantage of such technological changes brought by the 4IR, has not yet been measured. The primary objective of this study is to investigate IMSAf’s perceptions and readiness to embrace technological changes brought by the 4IR. The perceptions and readiness are assessed based on the technology embracing organisational framework of efficiencies, innovation, skills and re-training. This study is grounded in the philosophy of positivism and the related method used is a quantitative study to test the research questions in an objective manner. A questionnaire was the sole method of collecting first-hand data from the selected sample. The population size consisted of 139 respondents working in various business units within IMSAf. These individuals are occupying various roles and they have in depth, tacit, and multi-disciplinary knowledge of processes and would be the first to experience technological changes brought by the 4IR. A quantitative analysis technique is applied, such as descriptive and inferential statistics, to analyse data. A literature review on the topic was conducted as well as an empirical study. The results from both the literature review and the empirical study found that with the implementation of 4IR emerging technologies within an organisation, there is a significant improvement on efficiencies, innovation and skills and re-training. Furthermore, the level of awareness and understanding about the benefits of embracing 4IR emerging technologies within IMSAf is significant. , Thesis (MBA) -- Faculty of Business and Economic Sciences, NMU Business School, 2021

- Description: Energy is one of the vital natural resources that contribute towards an improvement in social and economic development. Environmental issues such as climate change have resulted in the exploitation of renewable energy gaining momentum. Renewable ocean energy is one of the renewable sources that have the potential to assist South Africa to achieve its energy policy goals, which include economic development and the management of energy-related environmental and health impacts. The exploitation and exploration of renewable ocean energy in South Africa raise legal concerns. These concerns are the lack of appropriate legal and regulatory frameworks and the possible conflicts among users in the marine environment that may occur as a result of the exploitation and exploration of renewable ocean energy. This dissertation, therefore, addresses these concerns by providing a critical assessment of the regulation of renewable ocean energy in South Africa. Firstly, it provides an introduction and legal background of renewable ocean energy. It proceeds by critically assessing the international requirements with which South Africa needs to comply regarding renewable ocean energy. Following that, the dissertation provides an analysis of the environment and energy legislation and the extent to which they regulate renewable ocean energy. Lastly, taking into account other existing and future activities in the marine environment, there is a discussion of the marine spatial planning (MSP) and other regulatory measures in so far as they relate to the resolution of the conflict in the context of renewable ocean energy. The conclusion is that the existing legislation does not appropriately regulate renewable ocean energy. As a result, the dissertation proposes how the existing legislation may adequately include renewable ocean energy. Furthermore, it makes recommendations. , Thesis (LLM) -- Faculty of Law, Public Law, 2021

The study employed a cross-sectional, correlational design to achieve the objectives. Additionally, a non-probability convenience sampling method was used. Data was collected from retail employees in Gauteng, Pretoria through a composite self-administered paper-and-pencil questionnaire which incorporated a biographical questionnaire, the PCQ-24 and the PWS. To determine whether a relationship exists between the constructs, Pearson’s product-moment correlations were used. To further determine demographical differences, the analysis of variance (ANOVA) was utilised, and post-hoc Tukey HSD tests were used to determine where the differences lie. Results indicated that PsyCap was positively correlated with wellness; and significant differences in the means for both PsyCap and wellness were observed for demographic variables. The study further revealed that PsyCap is predictive of employee wellness. , Thesis (MA) -- Faculty of Business and Economic Sciences, School of Industrial Psychology and Human Resources, 2021

- Description: It has been recognised in academic and policy debates that a poorly managed exchange rate can have a devastating effect on a country’s economic growth rate. The current literature on the effect of real exchange rate misalignment on economic growth shows mixed and inconclusive results. The floating rate regime by South Africa to which Namibia’s exchange rate is fixed, contributes to exchange fluctuations that Namibia experiences. As exchange rate is one of the fundamental factors that affect economic growth, this study aims to evaluate the effect of real exchange rate misalignment on the Namibian economic growth over the period from 1990 to 2018. The study employs Equilibrium Real Exchange Rate (ERER) Model and Auto-Regressive Distributed Lag (ARDL) models as quantitative research methods approach for estimating the equilibrium exchange rate and establishing the relationship between real exchange rate misalignment and Namibia’s economic growth. The ERER model reveals that the Namibian currency was overvalued over the period under review. Furthermore, the ARDL results confirm that a significant relationship exists between real exchange rate misalignment and Namibia’s economic growth. The study further shows that real exchange rate misalignment (overvaluation) negatively affects Namibia’s growth domestic product (GDP). Consequently, consistent with current literature, the study supports the view that keeping the real exchange rate at levels close to its equilibrium level or slightly below its equilibrium level can promote economic growth in developing economies such as Namibia. The study, therefore, strongly recommends that the Namibian government should consider a currency undervaluation policy in order to promote economic activities and enhance Namibia’s GDP. it is thus crucial for policymakers to effectively manage real exchange rate regularly and ensure that it does not widely deviate from its equilibrium value. The study also recommends that Namibia should diversify its products and ease the trade barriers so as to promote exports that would boost economic activities. , Thesis (MPhil) -- Faculty of Business and Economic Sciences, School of Economics Development and Tourism, 2021

- Description: This research was directed towards the current state of the relationship between the Performance Management Development System and compensation in the City of Cape Town Municipality. The research approach adopted in this study was a qualitative method. Desktop analysis and case study design were used as secondary data collection tools. Since the democratization of South Africa in 1994, the focus has been directed towards the maximising of economic growth and development. The road to development has been challenging since the inception of democracy. Organisations are operating in a dynamic and highly competitive environment which requires adjustments and development of strategies to remain relevant. Compensation is one of the ways different organisations have adopted as a strategy for attracting and retaining suitable employees as well as maintaining performance management. The essence of a well-functioning performance management development system has played a critical role in providing an effective system in the public service. The main objective of compensation is to ensure an organisation has the right resources necessary to motivate employees’ performance needed to achieve the organisational strategy. The study found that a compensation strategy leads to increased employees’ performance. The findings indicated that there is a positive connection between the compensation strategy and the performance of the employees. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2021

Data was collected from an online questionnaire survey sent to 141 Special Economic Zone employees who worked as non-managerial employees. Ninety-four employees responded. The collected data was analysed using statistical tools from SPSS 20. Subsequently, descriptive statistics, including frequencies, percentages, means and standard deviations and correlations were used to summarise information for demographic variables, authentic leadership and well-being. In addition, ANOVA was used to determine sub-group differences. First, it has been shown that project managers were seen by their subordinates as trustworthy leaders. Second, there was a connection between authentic leadership and well-being in the workplace. Third, it was discovered that all aspects of ethical leadership, apart from Work Intrusion (IoW), had a relationship with organisational well-being. Fourth, it has shown that males and females experience different levels of job satisfaction and feel differently about respect for the organisation.

- Description: The current study focused on the representation of women in isiXhosa drama books. The aim of the study was to understand how women are represented in these post-1990 dramas written by both female and male authors. Furthermore, the study aimed to look at whether the authors took note of developments made by African women in a broader context such as social, political, spiritual and economic spheres. The study followed a pragmatic approach which is useful to analyse drama, the meanings and the events related to situations. A discourse analysis was also applied as it is difficult to separate it from pragmatics. This means that the study outlined the correlation of pragmatics with discourse analysis and drama. Four isiXhosa books were selected which are Iinkunzi ezimbini by Hlumela Mothlabane 1994, Yeha mfazi obulala indoda 1997 and Kuphek’amadoda kupheth’abafazi We-ena! 2007 by Lubabalo Livingstone Ngewu and Imida by Nompumezo Buzani 2016. Episodes from the four selected isiXhosa drama books were identified. Upon identifying the episodes, they were categorised in to themes in order to highlight the representation of women in the books. This was done using a qualitative research method because it useful to be used in natural setting to understand meanings and social life. Many themes were identified in the four selected isiXhosa drama books. The dominating themes are women who are educated, employed and do not tolerate ill treatment. This shows that the authors in a way are paying attention to the events occurring post-1990 as some of these were not popular pre-1990. The study acknowledges that there is limited research conducted that analyses drama books from both male and female authors. Therefore, future studies could look into this. , Thesis (MA) -- Faculty of Humanities, School of Language & Literatures, Education, 2021

- Description: The white rhinoceros (Ceratotherium simum) (hereafter rhino) is under threat of becoming extinct due to continued poaching for its horns. In South Africa and elsewhere in Africa private landowners have, over the last few decades, contributed to the conservation of various species, including rhinos, even in areas where they have not occurred historically (i.e., where they are extralimital). Unfortunately, very few studies have investigated the conservation contribution of extralimital white rhinos on private reserves to the overall meta-population and/or their reproductive performance. The first aim of my study was therefore to determine whether or not the white rhinos introduced to a private game reserve in the Eastern Cape Province in 1992 have been successful from a reproductive perspective. I calculated inter-calving intervals, age at first calving, conception period, sex ratio, fecundity and fertility rates for white rhinos over this 28-year period. The average annual population growth rate for the rhinos was 10%, which is higher than the recommended 5% by the Rhino Management Group. Trends in density-dependent parameters such as age at first calving and inter-calving intervals also indicated that my study population is still well below carrying capacity for white rhinos and is contributing positively to white rhino conservation in South Africa. The second aim of my study was to investigate home range size and vegetation preferences of white rhinos. Home ranges were mostly larger for all age groups compared to rhinos in their native range. Previously cultivated lands (dominated by several grass species) were preferred by all rhino age groups. The rehabilitation of these previous agricultural-based pastures has likely contributed to the successful introduction of the white rhino as an extralimital megaherbivore in the Eastern Cape. I conclude that although extralimital white rhino populations in the Eastern Cape can be successful from a reproductive perspective, their potential impact on the indigenous biodiversity of the region should be a key future research priority. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2021

- Description: Poverty is prevalent in the Eastern Cape Province. As a result of poverty and other related factors, there is an increase on percentage of crime. There is a number of case laws where children have been found guilty of committing very serious criminal offences in the Eastern Cape. They are contributing high percentage in crime. In the past, before the dawn of the new constitutional dispensation, children in conflict with the law were not treated any different to adults who were in conflict with the law. There was no separate legislation that was child specific. , Thesis (LLM) -- Faculty of Laws, Criminal and Procedural Law, 2021

- Description: Almost three decades after the official end of the apartheid, South Africa has been on a sturdy path that is characterised by deepening spatial economic inequalities. A plethora of policy instruments unleashed since 1994 had not only failed to stem the tide of poverty and inequality, but had deepened them. As part of this, South Africa’s most ambitious social engineering programme – land reform -- had disappointing outcomes. Premised on a view that these apartheid continuities were embedded in South Africa’s land administration system – which was incoherent and fragmented and requiring a systemic overhaul -- the study sought to explore the potential role of Open Government Data (OGD) in the repurposing of land administration system in the post-apartheid South Africa. To achieve this goal, the study was guided by the following objectives: to explore the ontology and the state of land governance and administration in the context of the post-apartheid South Africa; to undertake an evaluation or assessment of South Africa’s land data ecosystem; and to explore the potential role of OGD in the repurposing of land administration system in the postapartheid of South Africa. This study was steeped in qualitative research methods, underpinned by primary and secondary literature review. While the study was primarily pitched on a national scale – the combination of the systems and multiple scales approaches – yielded results which dislodges solutions that are required outside of the domain of a single state. This is one glaring example of land governance complexities that straddle beyond national scale – specifically in respect of new policy trajectories on trans-national boundaries and governance of water resources. Based on the holistic ontology of land, this study concludes that land administration and land governance overarching conceptual orientation -- concerned with land use decisions made by humans at various scales from a praxis and policy perspective –constitute two sides of the same coin, the former steeped towards practice and the latter steeped towards policy. Drawing from decolonial theories the study concludes that land does not only have multiple dimensions, but it also has multiple meanings, in a manner that calls for an ontological shift away from the western ontology, towards an inclusive and holistic conceptualisation. Historiography that is anchored in de-colonial thinking of South Africa’s land governance helps us understand how and why – colonial/apartheid norms acrimoniously found their way into the post-apartheid order -- the post-apartheid institutions of modernity rest on the same hierarchies of identities, classification and pathologisation. The study concludes that, while the colonial/apartheid administration may be gone, it’s underlying power matrices continue -- i.e. capitalism/European/patriachal/white – in a manner which explains the continuities of South Africa’s spatial inequalities and the associated economic inequalities. The organising principle for land relations (including opportunities) continues to be underpinned by gender, race and class, in ways that expose the mythical dimensions of the 'post-apartheid' underbelly. While identifying the need for homogenisation and rationalistion of colonial, apartheid and post-apartheid institutions (on a national scale) that is insufficient for the transformation of the colonial situation of what is in essence a part of the global system, the study advocates for the ‘repurposing of land governance and administration’ – underpinned by de-colonial thinking. Repurposing is seen as political imaginary that would entail uncoupling thought processes and praxis from the colonial matrices of power. The study goes on to conclude that there is a definite role for Open Government Data in repurposing of land administration in the post-apartheid South Africa – as a necessary, though in and of it’s own it is an insufficient condition to achieve that ideal -- but presents an opportunity to enhance transdisciplinarity approaches and efficiencies in internal government functioning and evidence-based decision making and policy formulation processes. , Thesis (PhD) -- Faculty of Science, Geography, 2021

- Description: The goal of this research was to evaluate the role of strategic leadership in improving strategy implementation in the Eastern Cape Department of Health (ECDOH). According to literature, the strategic leadership actions, namely: determining strategic direction; managing the organisation’s resource portfolio; sustaining an effective organisational culture; emphasising ethical practices; and establishing balanced organisational controls, positively contribute to successful implementation of strategy. The research methodology used in this study was a quantitative research approach. The study used an online survey questionnaire to gather information on the respondents’ perceptions on the role of the strategic leadership actions in strategy implementation in the ECDOH. The survey also gathered respondents’ perceptions on the role of environmental complexity factors in moderating the relationship between the strategic leadership actions and strategy implementation in the ECDOH. The study revealed that determining strategic direction and establishing balanced organisational controls were positively related to strategy implementation in the ECDOH. Managing the organisation’s resource portfolio, sustaining an effective organisational culture as well as emphasising ethical practices were not positively related to strategy implementation in the ECDOH. The study also found that four out of the five environmental complexity factors measured, moderate the relationship between strategic leadership actions and strategy implementation in the ECDOH. Based on the findings, the study recommends that the ECDOH management apply all the strategic leadership actions in improving strategy implementation in the ECDOH and provides detailed recommendations per strategic leadership action. The study also recommends that the ECDOH management take note of the environmental complexity factors that moderate the relationship between the role of strategic leadership actions in the implementation of strategy in the ECDOH and develop plans to mitigate against the risk of these environmental complexity factors. , Thesis (MBA) -- Faculty of Business and Economic Science, NMU Business School, 2021

- Description: This thesis discussed the South African income tax implications, in terms of the Income Tax Act, No. 58 of 1962, arising from complying with Broad-Based Black Economic Empowerment requirements, and related principles established in case law. Various structures and transactions entered into for the purposes of earning points for the B-BBEE scorecard were identified. In the assessment of the deductibility of B-BBEE expenditure in terms of the preamble to section 11, section 11(a) and section 23(g) of the Act, it was highlighted that, in the South African economic environment, B-BBEE compliance represents a competitive advantage for entities. In addition, many South African organisations are required to comply with B-BBEE requirements for legal and regulatory purposes. The analysis of the deductibility of B-BBEE expenditure revealed that taxpayers that incur this expenditure would be carrying on a trade or commencing to do so. It was also concluded that B-BBEE expenditure is incurred in the production of income and would generally not be capital in nature, except in certain circumstances, in which case the Act provides certain allowances. Any deduction will only be allowed in the year of assessment in which the expenditure is actually incurred, or when the taxpayer incurs an unconditional legal obligation. This thesis explored several alternatives to achieve the requirements of the ownership element of B-BBEE and highlighted the income tax implications that arise because of these structures. It was also observed that there are a number of incentives in the Act that could be beneficial to taxpayers seeking to earn points for the remaining elements of the B-BBEE scorecard. A legal interpretive approach, in particular a doctrinal research methodology, was adopted in carrying out this research. This research concluded that the Act facilitates most of the B-BBEE transactions and structures, but due to the complex and sometimes uncertain nature of the tax consequences of B-BBEE transactions and structures, there is a need for further guidance in this area of tax law. , Thesis (MCom) -- Faculty of Commerce, Accounting, 2021

- Description: An employer may wish to change terms and conditions of employment in order to respond to the operational needs of a business. The definition of operational requirements is not limited to initiatives aimed at ensuring the survival of a business but include measures intended to improve its performance. Changes to terms and conditions of employment ordinarily locate themselves within the realm of interest disputes which are mainly resolved through the process of collective bargaining coupled with power play. This means that an employer may not dismiss employees within the context of collective bargaining as a way of compelling compliance with a demand in relation to matters of mutual interest. Section187(1)(c) of the LRA renders any dismissal automatically unfair if the reason for the dismissal is a refusal by employees to accept a demand in respect of any matter of mutual interest. The question that arises relates to the interpretation of this section and the impact thereof on the right of the employer to retrench as envisaged in section 188(1)(a)(ii) of the LRA. This reveals the intersection between collective bargaining and dismissals for operational requirements. In other words, changes to terms and conditions of employment equally influence the performance of the business thereby also fall within the definition of operational requirements. The question therefore is when do employers’ economic needs justify a dismissal of employees who rejects changes to terms and conditions of employment? Secondly, whether or not the relevant provisions, and the whole scheme of the LRA, require retrenchments to be the measure of last resort? These issues shall be explored in this treatise with reference to the relevant provisions of the LRA and relevant case law. , Thesis (LLM) -- Faculty of Law, Mercantile Law, 2021

- Description: Small, micro and medium businesses are regarded as the engine for achieving economic growth and reducing unemployment through unlocking the potential of young entrepreneurs. However, 80% of such young entrepreneurs operating SMMEs fail in their first years of existence. To respond to this challenge, Business Incubators (BI’s) have been established to nurture SMMEs to succeed. Numerous BI’s, such as Godisa, have been established in South Africa with many supported by the Department of Trade and Industry. However, there are still many potential entrepreneurs in need of such help. In this regard, Old Mutual initiated a programme similar to Godisa, called the Infinitum Incubation Programme (IIP). The IIP seeks to groom young, willing and educated entrepreneurs from previously disadvantaged backgrounds, with business skills to help them establish sustainable businesses. Their focus is on Financial Advisors and the programme has been running for two years offering all the support needed by young businesses. Against this background, this study endeavoured to assess whether the initiative has had the intended impact on the Incubatees. Using a qualitative and Interpretivism research approach and a sample of six incubatees, this study addressed its objectives. Questionnaires were sent out to all incubators and incubatees involved in the IIP and a response rate 60% was achieved. These responses were analysed through descriptive statistics and thematic analysis. The results show that the IIP has been successful in identifying suitable incubatees and stakeholders. It also found that the IIP has been successful in equipping incubatees with theoretical business management skills. However, in terms of skills transfer, the programme was not successful. Both incubatees and stakeholders rated the programme poorly. Further, both stakeholders and incubatees perceive the programme to be a very good idea and see potential for success; however, they feel that would be achieved only after significant improvement. The study recommends that the programme improve on the following: gender balance, management and coordination of the programme, improved skills transfer, balance between practice, theory, and providing post-programme mentorship. The study ends by describing limitations and areas for further research. , Thesis (MBA) -- Faculty of Business and Economic Science, NMU Business School, 2021

- Description: Series of compounds were screened using Schrodinger suite (Maestro). The DFT calculations were used for geometry optimization of the ligands using the B3YLYP functional and 6-31G basis set, and these structures were used for docking studies. Maestro was used to predict the activity of thiazole derivatives against HIV-1 protease. The range of estimated inhibition constants for these thiazole derivatives (65 nM-5 μM) indicate moderate to weak activity against HIV-1 protease, given that the activity of current protease inhibitors is typically found have experimental inhibition constants around 0.1-2.0 nM. Twenty compounds were selected based on the docking results and they were synthesized and characterized by NMR, FT-IR and elemental analysis. The cytotoxicity studies were done at two different concentrations (100 μM and 10 μM), using the brine shrimp bioassay. All compounds were highly toxic at 100 μM, with the percentage mortality between 20 to 75%. Eight compounds were selected for the enzyme bioassay based on the results obtained from lower concentration (10 μM). In the enzyme inhibition studies, the profile of HIV-1 activity was done at different inhibitor concentrations (800 μM – 10 μM) by measuring the cleavage of the synthetic substrate (Abz-Thr-lle-PNO2Phe=Gln-Arg-NH2) at excitation wavelength of 345/490 nm using fluorescence. Ligands 5 (unsubstituted derivative), 7 (4-nitro derivative) and 16 (4-methoxy derivative) gave percentage inhibition of 39, 45 and 42%, and this activity was very low compared to the activity of the positive control ritonavir (85% enzyme inhibition). Ligands 8 (4-methoxy derivative) and 12 (4-methoxy derivative) gave enzyme inhibition of 70% and 75%. These results suggest that the presence of the methoxy substituents ii increases activity of these compounds against HIV-1 protease. Most of the compounds gave good IC50 values between 12.5-42.7 nM. The bromo-substituted ligand 7 gave the lowest IC50 (12.5 nM). Ligand 11 also gave a good IC50 value of 14.86 nM. The bromo-substituted derivatives showed to be very active compared to other types of thiazole derivatives. Enzyme kinetics were carried out to compare the inhibition constants obtained via computational modelling. Ligand 7 (4-methoxy derivatives) binds better in the active site of HIV-1 protease than other compounds in Class B, with Ki = 50 nM, Km = 23.8 Nm and Vmax = 83.3 nM/min. The unsubstituted (L5), 4-bromo (L7) and 4-nitro (L8) substituted compounds gave inhibition constants of 100 to 112 nM. The in vitro testing yielded higher activity than that determined in silico. , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2021

In the enzyme inhibition studies, the profile of HIV-1 activity was done at different inhibitor concentrations (800 μM – 10 μM) by measuring the cleavage of the synthetic substrate (Abz-Thr-lle-PNO2Phe=Gln-Arg-NH2) at excitation wavelength of 345/490 nm using fluorescence. Ligands 5 (unsubstituted derivative), 7 (4-nitro derivative) and 16 (4-methoxy derivative) gave percentage inhibition of 39, 45 and 42%, and this activity was very low compared to the activity of the positive control ritonavir (85% enzyme inhibition). Ligands 8 (4-methoxy derivative) and 12 (4-methoxy derivative) gave enzyme inhibition of 70% and 75%. These results suggest that the presence of the methoxy substituents ii increases activity of these compounds against HIV-1 protease. Most of the compounds gave good IC50 values between 12.5-42.7 nM. The bromo-substituted ligand 7 gave the lowest IC50 (12.5 nM). Ligand 11 also gave a good IC50 value of 14.86 nM. The bromo-substituted derivatives showed to be very active compared to other types of thiazole derivatives. Enzyme kinetics were carried out to compare the inhibition constants obtained via computational modelling. Ligand 7 (4-methoxy derivatives) binds better in the active site of HIV-1 protease than other compounds in Class B, with Ki = 50 nM, Km = 23.8 Nm and Vmax = 83.3 nM/min. The unsubstituted (L5), 4-bromo (L7) and 4-nitro (L8) substituted compounds gave inhibition constants of 100 to 112 nM. The in vitro testing yielded higher activity than that determined in silico. , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2021

- Description: Infrared lens production demands a surface with a high degree of accuracy and integrity. Surface roughness is a critical index of the measure of any product’s surface integrity. As a result of this, ultra-high machining technology has enjoyed extensive application, due to the continuous request for components within the range of 1 – 10nm roughness value. This technology has brought about the increased productivity and manufacture of quality products with a top-notch surface finish. Brittle materials such as germanium are hard to machine through the conventional processes such as lapping and polishing. Hence, the ultra-precision machining technology based on single point diamond turning (SPDT), is now been applied to machine germanium in the ductile mode, where material chip removal occurs by plastic deformation instead of a brittle fracture. During machining, selecting the optimal cutting conditions which includes cutting parameters and tool geometry, will not only improve productivity but ensure the minimisation of operating cost. In this research work, SPDT operation was used to conduct two experiments on a (monocrystalline germanium) workpiece. The first experiment was carried out using a diamond tool with a 1.5 mm nose radius, while the second experiment employed the use of a tool having a nose radius of 1.0 mm. A combination of machining parameters for each of the experimental runs were derived from a Box-Behnken method of design and the surface roughness was measured at each interval for both experiments with the aid of a Taylor Hopson PGI Dimension XL profilometer. Acoustic emission (AE) was also used as a quality sensing and tool-monitoring technique, to acquire signals and give indications of the expected surface roughness. Predictive models based on response surface methodology (RSM) and artificial neural networks (ANN), were developed for determining surface roughness. Optimisation was performed using RSM to determine the optimal set of machining factors, which results in optimal condition of the output response. Further investigations on the acquired signals were carried out using signal-processing techniques. Time-domain and time-frequency domain features acquired from the AE signals, together with the process parameters, were employed as input variables in the neural network design, having shown a good association with the surface roughness. ix Conclusively, it can be observed that the predictive model results and the experimental roughness measurements are in good agreement with each other. For accuracy and cost of computation, the RSM and ANN developed models for single-crystal germanium are compared using mean absolute error (MAE). , Thesis (M.Eng) -- Faculty of Engineering, the built environment & Information Technology, 2021

- Description: This study examines evolving definitions of ukuziphatha kahle that historically relied on the preservation of virginity for Zulu girls, who participate in the umemulo ceremony that marks the transition from girlhood to womanhood. It examines notions of Zulu girlhood as understood through preservation - ukugcina isibaya sikaBaba - and through respectability and secrecy - ukuhlonipha nokufihla. The study analyses how conceptions of ukuziphatha kahle (good behavior) have evolved in the context of sexual rights in the performance of Zulu girlhood. It is located in the interdisciplinary literature of global girlhood studies, and African feminist lenses of womanhood and rites of passages. The study draws from 26 interviews with Zulu women who have gone through umemulo, elder women who facilitate virginity testing and umemulo; and female relatives of women who have gone through umemulo in Estcourt, Wembezi, Paapkalius Fountain, Ntabamhlophe and Cornfields in KwaZulu-Natal. This thesis contextualises umemulo and ukuziphatha kahle (good behaviour) in democratic South Africa. Umemulo is a ritual done for a Zulu girl whose behaviour is deemed to be good. While this is clear, what constitutes ukuziphatha kahle (good behaviour) is contested. On stricter terms, ukuziphatha kahle means to be intombi nto (a virgin). The interviews with women who went through umemulo show that most of them were not virgins at the time of the ritual. The elder and younger women expressed that ukuziphatha kahle for them goes beyond the girl’s virginity. Instead, they understand it as a girl who does not have a child, and who has shown respect and obedience to her parents and elders. Strikingly, the study shows an inter-generational collusion between the younger and elder women, who maintain the outward appearance of virginity of the girls who participate in umemulo. The study argues that there are variations of ukuhlonipha (respect), which in the rights context of democratic South Africa overlap into ukufihla (secrecy). Importantly, it is clear that the concept of being a good Zulu womanhood holds and remains important for Zulu girls and women. However, the ways in which Zulu women experience and perform this is complex. The findings show that while many Zulu girls want to be seen as performing accepted good Zulu womanhood, they do so in ways that allow them to enjoy their sexual rights and pleasure. This is not a tension. , Thesis (MA) -- Faculty of Humanities, Politial and International Studies, 2021

- Description: Soil erosion by water is the major source of soil degradation in the world, and South Africa (SA) is not an exception particularly in the Free State (FS) Province. In South Africa, the Caledon River Catchment in the FS Province has been identified as one of the regions where soil erosion has been prevalent for decades. Evidence across many parts of the catchment show a widespread of soil erosion and the contaminant flux associated with sediment into river systems and reservoirs; including the Welbedatcht dam and Carthcart-drift dam in Ladybrand. It is of these issues that the current work aimed at enhancing the understanding of sediment sources and soil erosion dynamics at the Caledon River Basin. The objectives of the study were to locate sources of suspended sediments and to assess and quantify the contribution of Land Use Cover (LUC) classes to water erosion and sediment yield at a sub – catchment level of the Caledon River Basin. To achieve the objectives set out for this research, a study was conducted at a sub - catchment level of the Caledon River Basin in the FS Province, South Africa. The sediment–fingerprinting approach and the Revised Universal Soil Loss Equation (RUSLE) model were used in the study under Geographic Information System (GIS) settings. A qualitative and quantitative interpretation of the geochemical data were used to evaluate the potential for distinguishing catchment sediment sources. The application of multivariate sediment mixing models incorporating Monte Carlo simulations was undertaken to investigate recent variations in sediment sources. Lastly, to document the impact of LUC change on soil erosion; data from soil profile database, Landsat 8 OLI–TIRS and climate (i.e. rainfall) were used to assess and map the spatial and temporal pattern changes of soil erosion at a sub – catchment level as related to LUC changes. In this study, the sub–catchment was classified into 6 LUC classes. Thereafter soil erosion was quantified for three consecutive years namely; 2015, 2016 and 2018 using the soil erosion factors as GIS–layers. The investigation of sediment source types and spatial provenance in the catchment showed that the grassland areas have consistently been the main sediment source (83 percent) throughout the study period. Findings further showed that there was an increase in contributions from cultivation and abandoned cultivated fields. Sediment contribution from surface sources was dominant (54 percent) and thereafter, subsurface sediment input increased (62 percent). This trend is indicative of increased severity of gully erosion in the area and thus is consistent with other studies. To comprehend the influence of LUC class modification dynamics on soil erosion, water erosion in particular at the sub-catchment commencing from 2015 to 2018 (4 years), multi-temporal Landsat 8 information jointly with the RUSLE model were used. A post-classification, LUC class alteration comparison revealed that water bodies, shrubs and forested region and grassland declined by 0.27 percent, 15.60 percent, and 37.60 percent, respectively. On the other hand, regions under Bad lands, and bare-soil and built-up regions including agricultural region expanded by 2.22 percent, 5.78 percent, and 45.67 percent respectively, between 2015 to 2018 study period. The average yearly soil loss decreased at the sub-catchment and was 10.23,5.71 and 5.82 t ⋅ ha -1 ⋅ yr-1 for 2015, 2016 and 2018 respectively. Although soil loss lessened for the duration of the perceived period, a closer scrutiny revealed that there were nonetheless seeming signs of persistent escalation in soil loss risk. These signs were mostly shown in the elevated parts of the sub-catchment as shown by the red regions on the soil loss map. Additional examination of soil loss findings by LUC classes categories further indicated that most LUC classes categories, including Bare-soil and built-up area, agricultural-land, grassland, and region under shrubs and forests, showed increased soil loss levels during the 4 years’ study period at the sub-catchment. The information on the comparative vividness of diverse sediment sources given by the study must be observed as a noteworthy development towards an understanding of the sediment source dynamics in agricultural river based catchments; more so of the Caledon River Basin. Further research is recommended for other erosion prone catchments in South Africa to identify additional evidence of the spatial and temporal variations in soil erosion and sediment sources. The results of the study suggest that the procedure of assimilating the GIS and RS with the RUSLE model is not just precise, time-efficient and exact in recognizing soil erosion susceptible regions in geospatial and temporal standings. However, it is a cost-efficient substitute to standard field-founded approaches. , Thesis (MSc) (Soil Science) -- University of Fort Hare, 2021
