- Description: My thesis is a fragmented, non-linear novella, comprised predominantly of experimental prose- poetry and fiction short-stories. I have chosen this approach in form to further explore my interest in ancestry and trauma, death and image-making, “reality” and fantasy, and the tension these invisible barriers create between the inner and outer worlds in which we simultaneously navigate, remember and forget. This thesis has been influenced both in form and content by the works of Eduardo Galeano, Osama Alomar, Lidia Yuknavitch, Susan Steinberg, Claudia Rankine, Lance Olsen, and Yasunari Kawabata, among others.

- Description: Background and aim: Flight attendants forms a significant part in 24-hour aviation industry. Flight attendant fatigue is a significant problem in the aviation industry as it continues to jeopardize the ability to fulfil important safety and security roles which is critical in performance duty of a flight attendant. However, little attention has been accomplished to the workload, working conditions and fatigue of flight attendants crew in transport aircraft. In addition, there is currently less research that have also embraced the problematic of smaller regional/commercial operation (short-haul flight operations) inducing fatigue among short-haul flight attendants as the nature of this operation are often characterised with high productivity expectations in a demanding environment with high time pressures resulting in high workloads and fatigue. Thus, flight attendant fatigue and workload is a worldwide challenge in this operational environment and less attention has been given to the determining factors. Therefore, the aim of the study was to determine the workload factors contributing to flight attendant fatigue during short-haul flight operations. Methods (System analysis): To achieve the research aim, the work system analysis, based on the Smith and Carayon-Sainfort model was chosen as the main research approach which was conducted in two ways; based on existing literature and secondly based on expert interviews. This method provided a systemic aspect to understand the whole work system of flight attendants work during short-haul operations in order to identify all the contributing factors to flight attendant fatigue and workload. Results: The literature analysis and the data from the expert interviews highlighted significant findings to flight attendant fatigue and workload. The reasons for flight attendant fatigue operating short-haul flights can be found at organizational, task, individual, environmental levels and tools and technologies and due to the interaction of the factors. The main factors of flight attendants’ fatigue are thought primarily as a function of scheduling due to irregular, mixed schedules with early starts and late finishes, extended duty days (long working hours), as well as high workload, due to the short turnaround flights, the number of sectors flown in a single duty period and duty length and high jobs demands. In addition, flight duty and rest regulations, confined work space in the cabin, vibrations, noise and lighting, sleeping in an unfamiliar environment, family responsibilities all add to additional stress placed on the body which can influence workload and sleep and consequently influencing fatigue. Conclusion: Overall the study determined that flight attendant fatigue is a significant problem in modern industry of short-haul operations. Using this systematic approach (work system analysis based on the framework of the work system model developed by Smith and Carayon-Sainfort (1989) allowed for an accurate representation of the complexity of flight attendant work environment in short-haul aviation industries, thus contributed to an increased understanding of fatigue and risk factors that span the entire work system and aid in identifying the patterns in combination of work system variables that are associated with increased risk to flight attendant fatigue. Overall flight attendant fatigue is a product of interactions with the short-haul environment. It can have a negative impact on safety, performance and well-being. Therefore, it needs to be managed and dealt with in the near future.

- Description: In the context of tourism, the community is seen as one of many stakeholders, with the other stakeholders being the tourism product owners, the government and tourism marketers. An understanding of a particular community’s perceptions and attitudes and how these perceptions are shaped concerning tourism development is important for decision-makers. The knowledge and involvement of the community in tourism related matters often determine the success of tourism development. The key element of effective planning for tourism is involving the local community and paying attention to their ideas, needs and aspirations, regarding tourism development in their community. Therefore, the aim of this study was to determine Tokyo Sexwale residents’ perceptions of the socio-cultural impacts of tourism in Jeffrey’s Bay. In order to address this aim, the following research objectives were formulated: To conduct a comprehensive literature review on residents’ perceptions of the socio-cultural impacts of tourism; To ascertain the levels of knowledge of Tokyo Sexwale residents about tourism; and To investigate the Tokyo Sexwale residents’ perceptions of the socio-cultural impacts of tourism in Jeffrey’s Bay. In an attempt to address the objectives of this study, a quantitative research approach was adopted. Using the non-probability sampling method, specifically, convenience sampling, the data was collected by conducting the fieldwork in Tokyo Sexwale community in Jeffrey’s Bay from the beginning of June 2019 until the end of August 2019. As a result, completed questionnaires were collected from a sample size of 400 respondents. The findings revealed that 34.7 percent of the respondents were young and aged between 26-35 years. Twenty-seven (27.0) percent of the respondents have been residing in the community for six to ten (6-10) years. A substantial number of respondents had completed a secondary qualification (75.3 percent). The findings further revealed that the majority of respondents were knowledgeable about the statement “Tourism includes holiday trips, travelling away from home for recreational and business purposes” (91.5 percent). Half of the respondents indicated that they interact with tourists more frequently when they visit their area, purchasing goods and services (50.0 percent). With respect to positive and negative socio-cultural impacts of tourism, the findings revealed that 63.5 percent of respondents indicated that tourism has improved the image of Jeffrey’s Bay, while 49.5 percent of respondents indicated that traditional culture is being commercialised as a result of tourism. This study recommends that the local government and tourism businesses in Jeffrey’s Bay should implement community tourism awareness programmes to educate local residents about the potential positive and negative socio-cultural impacts of tourism. This will ensure that local residents of Tokyo Sexwale community are aware of such impacts and reject tourism developments that will be harmful to their community and support those that will benefit them.

- Description: This work describes research undertaken towards the development of a Capability Maturity Model (CMM) for Cyber Ranges (CRs) focused on cyber security. Global cyber security needs are on the rise, and the need for attribution within the cyber domain is of particular concern. This has prompted major efforts to enhance cyber capabilities within organisations to increase their total cyber resilience posture. These efforts include, but are not limited to, the testing of computational devices, networks, and applications, and cyber skills training focused on prevention, detection and cyber attack response. A cyber range allows for the testing of the computational environment. By developing cyber events within a confined virtual or sand-boxed cyber environment, a cyber range can prepare the next generation of cyber security specialists to handle a variety of potential cyber attacks. Cyber ranges have different purposes, each designed to fulfil a different computational testing and cyber training goal; consequently, cyber ranges can vary greatly in the level of variety, capability, maturity and complexity. As cyber ranges proliferate and become more and more valued as tools for cyber security, a method to classify or rate them becomes essential. Yet while a universal criteria for measuring cyber ranges in terms of their capability maturity levels becomes more critical, there are currently very limited resources for researchers aiming to perform this kind of work. For this reason, this work proposes and describes a CMM, designed to give organisations the ability to benchmark the capability maturity of a given cyber range. This research adopted a synthesised approach to the development of a CMM, grounded in prior research and focused on the production of a conceptual model that provides a useful level of abstraction. In order to achieve this goal, the core capability elements of a cyber range are defined with their relative importance, allowing for the development of a proposed classification cyber range levels. An analysis of data gathered during the course of an expert review, together with other research, further supported the development of the conceptual model. In the context of cyber range capability, classification will include the ability of the cyber range to perform its functions optimally with different core capability elements, focusing on the Measurement of Capability (MoC) with its elements, namely effect, performance and threat ability. Cyber range maturity can evolve over time and can be defined through the Measurement of Maturity (MoM) with its elements, namely people, processes, technology. The combination of these measurements utilising the CMM for a CR determines the capability maturity level of a CR. The primary outcome of this research is the proposed level-based CMM framework for a cyber range, developed using adopted and synthesised CMMs, the analysis of an expert review, and the mapping of the results.

- Description: 2015 marked the year students went to great lengths to call on Higher Education institutions and their educators for a decolonised curriculum. This behaviour is attributable to the conditions that they had do study in. Buildings and campuses have colonial names, lectures mostly include White people’s intellectual contributions. Colonialism included colonial knowledge and denied African practices and existence. For centuries African philosophy was excluded and marginalised, which caused much pain and inhumanity. Higher education institutions remain detached from the developmental changes of African communities. Silence in academic disciplines was overwhelming Eurocentric / Westernised. Transformation of Higher Education curriculum in South Africa requires inclusion of African philosophy, and acknowledgement and respect for other cultures’ values, languages and knowledge. Educators play a pivotal role in transferring knowledge to students and producing the leaders for the future. Colonisation has ruled for decades and the effects thereof are still felt in various aspects of life. The education platform can break colonialism and if allowed, bring restoration to indigenous people. South African universities can contribute to society in transforming and decolonising curriculum and giving indigenous people and knowledge their rightful place. An education system free from colonialism positions students to add value to society as their worldviews are taken into consideration. This paper investigates the factors that could lead to a decolonised curriculum. Higher Education institutions have a role to play in ensuring a University free form colonial power and inequality. Decolonisation of the intellectual landscape will result in the decolonisation of the mind.

- Description: The Tsitsa Project focusses on land use management and rural livelihoods in the Tsitsa River catchment in the Eastern Cape Province of South Africa. It is funded by the Department of Environmental Affairs and the environmental monitoring initiative is implemented by Rhodes University, where I am employed as the catchment coordinator. This study explores the environmental monitoring initiative within the bigger Tsitsa Project. Community members in the catchment monitor sediment transportation in the Tsitsa River and its tributaries, which originally became of interest because it is proposed that a dam (Ntabelanga Dam) be established here. This study aims to understand citizen environmental monitoring in the Tsitsa Project; what the project managers regarded as benefits; and how the monitors themselves perceived benefits of participating as monitors. A realist approach was followed, in order to understand the connections between the context and the mechanisms in the project, and how these combined to result in the outcomes observed. Realist research emphasises the importance of context in shaping outcomes such as the achieved benefits of citizen monitoring. Data was collected using a case study method, where each individual monitor and their particular context, was regarded as a case. Semistructured interviews were conducted with 17 monitors and five Tsitsa Project staff; this was supported by field notes and the reviewing of project documents including field reports. The realist analysis looked at the context of the monitors in general and the mechanisms applied by the project in recruiting, training and managing the monitors. A second layer of mechanisms was identified as those responses from the monitors to what the project was introducing to them. Outcomes were both positive and negative, including how long monitors remained in the initiative, what benefits they derived from the process, and what potential benefits they did not achieve. This included lost opportunities to provide recognition for skills and experience gained. Recommendations are made regarding the recruitment, training and management of monitors, to optimise benefits for the monitors, the host institution and the initiative’s staff. The study is significant because of its particular yet representative characteristics and it will assist both the Tsitsa Project, which aims to expand its citizen environmental monitoring initiative, as well as wider Natural Resource Management Programmes in South Africa. It is also hoped that it will contribute to the literature on environmental monitoring as a little researched form of citizen science globally.

- Description: Mixed liquor includes consortia of microalgae and bacteria produced in high rate algal oxidation ponds (HRAOPs). The consortia of microalgae and bacteria occur as flocs called microalgae-bacterial flocs (MaB-flocs). This study aimed to source bacteria from MaB-flocs generated in HRAOPs and, after isolation and identification, evaluate their potential as plant growth promoting (PGP) microorganisms. Twelve bacterial strains namely ECCN 1b, ECCN 2b, ECCN 3b, ECCN 4b, ECCN 5b, ECCN 6b, ECCN 7b, ECCN 8b, ECCN 9b, ECCN 10b, ECCN 11b, and ECCN 12b were successfully isolated and their molecular identity established using amplified 16S rRNA gene sequence analysis that was compared to sequences deposited in the NCBI gene database. Blast analysis identified these isolates at the genus level as Bacillus strain ECCN 1b, Fictibacillus strain ECCN 2b, Bacillus strain ECCN 3b, Aeromonas strain ECCN 4b, Exiguobacterium strain ECCN 5b, Arthrobacter strain ECCN 6b, Enterobacter strain ECCN 7b, Exiguobacterium strain ECCN 8b, Microbacterium strain ECCN 9b, Pseudomonas ECCN strain 10b, Ancylobacter strain ECCN 11b and Microbacterium strain ECCN 12b. These isolates were able to grow in nutrient broth in a pH range between 6 and 10, with the best growth achieved at pH 8 to 9. The results on the use of carbon substrate revealed that 5 strains including Arthrobacter strain ECCN 6b, Aeromonas strain ECCN 4b, Pseudomonas strain ECCN 10b, Enterobacter strain ECCN 7b and Bacillus strain ECCN 3b were capable of using glucose, sucrose and mannitol. No faecal coliforms were found. However, of the 12 isolates screened for bio-fertilisation potential, Bacillus strain ECCN 1b, Fictibacillus strain ECCN 2b, Bacillus strain ECCN 3b, Aeromonas strain ECCN 4b, Exiguobacterium strain ECCN 5b, Arthrobacter strain ECCN 6b, Enterobacter ECCN strain 7b, Exiguobacterium strain ECCN 8b and Pseudomonas strain ECCN 10b showed multifunctional plant growth promoting (PGP) potential. The potential for PGP included the production of ammonium-N, solubilisation of phosphate-P and potassium-K, oxidation of Mn and production of auxin, indole-3-acetic acid (IAA). Results are discussed in terms of the amount or concentration (mg L-1) of plant essential nutrient and growth regulator produced by these isolated bacteria. Even so, further studies are needed to test and confirm the bio-fertiliser and plant growth promoting activity of these strains in pot trials and field experiments, or both.

The consortia of microalgae and bacteria occur as flocs called microalgae-bacterial flocs (MaB-flocs). This study aimed to source bacteria from MaB-flocs generated in HRAOPs and, after isolation and identification, evaluate their potential as plant growth promoting (PGP) microorganisms. Twelve bacterial strains namely ECCN 1b, ECCN 2b, ECCN 3b, ECCN 4b, ECCN 5b, ECCN 6b, ECCN 7b, ECCN 8b, ECCN 9b, ECCN 10b, ECCN 11b, and ECCN 12b were successfully isolated and their molecular identity established using amplified 16S rRNA gene sequence analysis that was compared to sequences deposited in the NCBI gene database. Blast analysis identified these isolates at the genus level as Bacillus strain ECCN 1b, Fictibacillus strain ECCN 2b, Bacillus strain ECCN 3b, Aeromonas strain ECCN 4b, Exiguobacterium strain ECCN 5b, Arthrobacter strain ECCN 6b, Enterobacter strain ECCN 7b, Exiguobacterium strain ECCN 8b, Microbacterium strain ECCN 9b, Pseudomonas ECCN strain 10b, Ancylobacter strain ECCN 11b and Microbacterium strain ECCN 12b. These isolates were able to grow in nutrient broth in a pH range between 6 and 10, with the best growth achieved at pH 8 to 9. The results on the use of carbon substrate revealed that 5 strains including Arthrobacter strain ECCN 6b, Aeromonas strain ECCN 4b, Pseudomonas strain ECCN 10b, Enterobacter strain ECCN 7b and Bacillus strain ECCN 3b were capable of using glucose, sucrose and mannitol. No faecal coliforms were found. However, of the 12 isolates screened for bio-fertilisation potential, Bacillus strain ECCN 1b, Fictibacillus strain ECCN 2b, Bacillus strain ECCN 3b, Aeromonas strain ECCN 4b, Exiguobacterium strain ECCN 5b, Arthrobacter strain ECCN 6b, Enterobacter ECCN strain 7b, Exiguobacterium strain ECCN 8b and Pseudomonas strain ECCN 10b showed multifunctional plant growth promoting (PGP) potential. The potential for PGP included the production of ammonium-N, solubilisation of phosphate-P and potassium-K, oxidation of Mn and production of auxin, indole-3-acetic acid (IAA). Results are discussed in terms of the amount or concentration (mg L-1) of plant essential nutrient and growth regulator produced by these isolated bacteria. Even so, further studies are needed to test and confirm the bio-fertiliser and plant growth promoting activity of these strains in pot trials and field experiments, or both.

- Description: The continuous flow synthesis of trimethoprim, an antibiotic, was investigated in this study from simple commercially available reagents, such as aniline and dimethylamine. The first step of the synthesis involves a highly exothermic Michael reaction, between acrylonitrile and dimethylamine; process intensification through miniaturization provides a safe and efficient method of synthesis through the use of microreactors. This is afforded by their large surface area-to-volume ratio; one of the many characteristics of continuous flow synthesis that allows for rapid heat dissipation allowing for exothermic reaction to be conducted safely at ambient or higher temperatures. This study was optimized on a Chemtrix Labtrix® Start unit using a Chemtrix reactor achieving a conversion of 99% in 12 sec residence time at 25oC. Subsequently the base catalyzed condensation of the intermediate with 3,4,5- trimethoxybenzaldehyde was investigated using Little Things Factory reactors (Channel diameter: 1.0mm). Maximum conversion (100%) was obtained at 80oC in 20 mins. Due to the poor cyclisation observed with this intermediate, according to literature findings, the 3-dimethylamino group was substituted for aniline. The optimisation for this acid catalysed substitution reaction was performed on a homemade PTFE tubing reactor (Diameter: 0.5mm) and it was found that at 120oC in 10 mins residence time a conversion of 97% was obtained. From the results obtained, an investigation into an integrated process for the condensation and substitution reaction was done using the Little Things Factory system (Channel Diameter: 1.0mm) coupled with a homemade PTFE coil reactor (Diameter: 0.5mm). This process, under optimum conditions of temperature 80oC and residence time of 30 mins, attained a conversion of 76%.

- Description: Exploitation of fish populations can exacerbate the effects of climate change, yet our understanding of their synergistic effects remains limited. As fish are increasingly exposed to temperatures on the edges of their optimal thermal performance window, their physiological response is expected to shape their future performance. It is therefore concerning that exploitation can select for specific physiological phenotypes, as this may affect fished populations’ physiological response to temperature change. A recent laboratory study revealed fewer high-performance metabolic-scope phenotypes in an exploited population of the marine Sparid Chrysoblepus laticeps across a range of experimental temperatures in comparison to an unexploited population. This suggested that individuals in exploited populations may have less available energy for aerobic performance at thermal extremes, which may reduce the resilience of the population to changes in temperature. However, since laboratory experiments exclude numerous other variables that fish encounter in the wild, it was necessary to test this finding in a natural setting. This thesis aimed to further develop the laboratory study by assessing whether exploitation effects the wild energetic response of C. laticeps to thermal variability. To achieve this, the field metabolic rate of C. laticeps, a resident and endemic South African fish, from a near-pristine population (Tsitsikamma National Park) and a heavily exploited population (Port Elizabeth) was compared using acoustic accelerometry. A laboratory-based study using a swim-tunnel respirometer and accelerometer transmitters was conducted to develop a model to predict metabolic rate from acceleration data at temperatures from 10 to 22⁰C. Acceleration, temperature, mass and population (exploited/unexploited) were found to be the best predictors of the metabolic rate of C. laticeps and were incorporated into the model to estimate the field metabolic rate of fish tagged with acoustic accelerometers in the wild. To examine the combined effects of temperature and exploitation on the field metabolic rate of C. laticeps in their natural state, two fine-scale telemetry arrays with temperature loggers were used to assess the acceleration of the fish across different temperatures in the wild for three months during a period of high thermal variability. Ten fish from the exploited and unexploited populations were caught, surgically implanted with accelerometer transmitters and released back into the wild. Close to 500 000 and 400 000 acceleration estimates were recorded from wild exploited and unexploited fish, respectively. The field metabolic rate of both populations was estimated by combining the field acceleration and temperature data with the laboratory calibration model. The field metabolic rate of C. laticeps from the exploited population was constrained near cold and warm extremes compared to no constraints observed in the unexploited population. This was attributed to reduced inter-individual variability in the field metabolic rate-temperature relationship within the exploited population. There appeared to be a greater proportion of individuals that maintained a high field metabolic rate at extreme temperatures in the unexploited population. In contrast, all but one fish from the exploited population did not maintain a high field metabolic rate at extreme temperatures. These findings aligned with the laboratory-based metabolic-scope study on both populations of C. laticeps and demonstrate that passive-fishing may be removing thermally tolerant individuals and rendering exploited populations less resilient to thermal change. These findings are discussed in the context of fisheries management and particularly on the role that marine protected areas could play in maintaining physiological diversity, and therefore the resilience of fish in the Anthropocene. This study highlights the importance of applied conservation physiology in understanding the consequences of fisheries-induced evolution in an increasingly variable climate.

- Description: Electronic Tax is a convenient system that enables taxpayers to submit their tax returns electronically, from home or from the office at any time of the day during the tax filing season. However, the electronic tax system has faced challenges over the years and to date. Thus, the reason for this study was to recommend user experience and usability principles for the electronic tax system to enhance the experience of taxpayers when using the electronic tax submission system. These principles contributed to improving the electronic tax system and increasing the adoption of the system among taxpayers who still submit their tax returns, manually. The study firstly described the problem, which forms part of the foundation for this research, namely development, which then led to the research questions and objectives, forming the core for the development of this study. User experience and usability principles are available for an online system, but there are limited studies on these factors regarding the electronic tax system. This study emphasized the importance of applying the user experience and usability principles to the electronic tax system. The various factors that affect the South African electronic tax system as a case study, have also been identified, including those that prompt other taxpayers to file at the SARS branch. As a result, to prove this theory, a questionnaire was sent only to electronic taxpayers to investigate how they perceive the electronic tax system. It can be concluded that the system has both advantages and disadvantages. An advantage is that the electronic tax system enables taxpayers to submit returns online from home or the office, instead of waiting in queues at the SARS branch. Disadvantages include that some taxpayers are concerned that their information is not safe and some encounter error messages and solutions while interacting with the system and these are not in a simple language for them to understand and recover. The user experience and usability principles have been recommended based on the responses obtained from the questionnaire.

- Description: The global automotive industry faces an emerging turning point where an unceasing dependence on costly fossil fuels and a growing concern over global warming is driving the industry to form new possibilities. A major challenge for decision makers is to assure that the consumer market is informed about both the advantages and disadvantageous of electric vehicle technology. A significant amount of research has been done on both the operational ability of electric vehicles and consumer resistance and preferences towards new technology and the marketing of electric vehicles. Given the retail relationship between key industry stakeholders such as the Original Equipment Manufacturers, franchised dealership network and potential electric vehicle consumers, the transition towards new electric vehicle technology represents an important strategic realignment for dealerships in order to sell electric vehicles along with traditional internal combustion engine vehicles and questions their operational capacity to do so successfully. The primary data was collected from a sample of forty respondents by means of an online questionnaire. The questionnaire was designed from literature and using similar extracts from other electric vehicle consumer resistance studies questionnaires. An email containing a Universal Resource Link (URL) to the questionnaire was sent and by means of snowball sampling, a representative sample of forty-eight respondents participated in the study who fully completed all the sections of the questionnaire. Interviews were conducted with Senior Management of local dealerships in the Port Elizabeth area. The interviews were executed in the same method as a ‘walk-in’ potential customer. Participation therefore was based on the willingness, readiness and availability of management. Three dealerships who already sell electric vehicles as well as two dealership who still only sell traditional internal combustion engine vehicles participated in the interviews. In addition, the National Automobile Dealers Association (NADA) commented on the strategic realignment of the South African industry as a whole. The results indicated that the majority of respondents believed that electric vehicles were a suitable alternative to the traditional internal combustion engine vehicle and were willing to personally contribute to improved sustainable mobility. Uncertainty remained with consumers and there was unwillingness to purchase and electric vehicle within the next five years. Electric vehicles were also believed to perform better but there was uncertainty about the return that would be achieved from investment in an electric vehicle despite the reduction in their carbon footprint and the associated image boost with family and colleagues. Furthermore, there appeared to be an alignment amongst the interviewees that South Africa does not face and immediate threat in terms of electric vehicles as the anticipated tipping point is envisaged to be in the region of 2030 onwards, however NADA as a professional industry body still warns that this is not a set point in time and that market forces could change the outlook and adaption dramatically.

- Description: The aim and scope of this study is to analyse the novel Yakhal’ Indoda (2010) written by Siphiwo Mahala. Since this book was written in the period known as the modern times in the new South Africa, it therefore tends to focus on the issues that disturb the peace of the citizens of South Africa exactly in this period of democratic South Africa. For that reason, the objective of this study is to associate the factors which Mahala has written about with those that are found in the contemporary South Africa which are regarded as issues disturbing the lives of South Africans at present. As it is of importance before the researcher deals with the central issue, there has to be a thorough knowledge of the theory of the subject that is being discussed at hand. The Literature Review with regard to this study takes into account the books written by Satyo, Duka, Brooks and Warren, to mention just a few. These authors, from their different academic perspectives, do their best on explaining the theory of the issues that will be discussed in this study. The Theoretical Framework that will be used in this study consists of the views of the writers who fought for a better political dispensation in the countries that were previously colonized. In this regard, the views of Ngùgì wa Thiong’o, and those of Steve Biko will be assessed in this study. The method that will be used in conducting this research is none other than that of Text Analysis. This simply means the researching student will focus mainly on the books found at the UFH library and other libraries. The chapter titles and their relevant outlines follow below: Chapter One is an introduction for this entire research. This chapter focuses more on the aims of this study, the importance or significance, limitations, methodology to be followed. Furthermore, this chapter gives a brief background of the author of the novel that will be analysed as well as the background of the novel. Chapter Two focuses on the theory of this research. This will be done through two theories. The researcher will first present a theory of the novel, as well as the Postcolonial theory. Under the novel theory, the researcher will discuss some vii features of the novel. However, the researcher’s emphasis will be on the theme that underlies in Mahala’s novel, Yakhal’ Indoda (2010). Chapter Three focuses on the theme of this research. The researcher will analyse the way Mahala portrays crime, corruption, unemployment and poverty in his novel. The researcher then will validate Mahala’s point of view against other authors with regards to the identified problems. Chapter Four focuses on the problems found in the Department of Education as well as rights of women as depicted in Mahala’s novel, Yakhal’ Indoda (2010). This will be accomplished through validation of the experienced and witnessed events in the new South Africa. Chapter Five focuses on the factors and events that are commonly associated with the Departments of Health and in Local Government, which are life threatening to society. This will be done by the researcher, pointing out some problems that Mahala in his book Yakhal’ Indoda (2010) attributes to the mentioned departments. Chapter Six is the general conclusion and exegesis on the study. This chapter gives a brief summary of the previous chapters, the findings regarding this study.

- Description: With a focus on my artistic practice, this paper seeks to interrogate the tensions and overlaps in various representations of transcendence that have shaped my spirituality by interrogating how these have featured in Eurocentric Christian iconography and Zambian cultural practices, particularly cultural artefacts used for spiritual flight, housed in Zambian museums. Transcendence is understood by some as a change in a person’s physiological or psychological state that allows them to go beyond their experience of time, place or being. I understand transcendence to be the moment that one’s spirit is elevated beyond the limitations of their physical body. The use of Biblical text relating to flight will also be discussed as a comparative study to explore how transcendence through flight operates within Christianity and a Zambian cultural context. Furthermore, I shall interrogate how black artists (particularly Zambian), such as Laurence Yombwe, address the omission of black people from Christian iconography (which is predominantly depicted as white people). I aim to highlight the important role that representation plays in allowing for an individual to experience transcendence. I believe inculturation is a fitting solution to address some of the pitfalls in Christian iconography brought about due to the lack of representation of black people. Inculturation can be understood as an adaptation in the way the gospel of Jesus is preached to non-Christian cultures, and in turn, how these cultures influence the teachings of the gospel. Finally, I will explore how transcendence as a concept applies in my artworks and how the materials I use highlight this concept. Through my art, I grapple to combine what seem like disparate spiritual paradigms, arising from my culture and my faith. My artwork seeks to contribute to the work that particular artists (a majority of them black) are grappling with to correct the lack of representation of black people in Christian iconography. I will use the notion of inculturation as an avenue through which to interrogate the tensions I experience while exploring the concept of transcendence.

- Description: With a focus on my artistic practice, this paper seeks to interrogate the tensions and overlaps in various representations of transcendence that have shaped my spirituality by interrogating how these have featured in Eurocentric Christian iconography and Zambian cultural practices, particularly cultural artefacts used for spiritual flight, housed in Zambian museums. Transcendence is understood by some as a change in a person’s physiological or psychological state that allows them to go beyond their experience of time, place or being. I understand transcendence to be the moment that one’s spirit is elevated beyond the limitations of their physical body. The use of Biblical text relating to flight will also be discussed as a comparative study to explore how transcendence through flight operates within Christianity and a Zambian cultural context. Furthermore, I shall interrogate how black artists (particularly Zambian), such as Laurence Yombwe, address the omission of black people from Christian iconography (which is predominantly depicted as white people). I aim to highlight the important role that representation plays in allowing for an individual to experience transcendence.

- Description: To the extent that teleological thinking is metaphysically suspect, many theorists attempt to shift the stigma of functional explanations by reducing function ascriptions, and aim thus to de-legitimise an appeal to teleological causal relations in an analysis of function. The point is to dispel the mystery which envelops the application of function concepts by reformulating biological functional explanations so as to dispense with teleology. My project is to interrogate the success with which teleological explanations have thus been eliminated in the biological sciences, and, over the course of this thesis, I conclude that a kind of teleological causation nevertheless remains the most adequate explanatory ground of natural products. My proposal is that functional explanations are causal explanations for the presence and maintenance of self-reproducing systems. I contend that, insofar as the attribution of function presupposes the valuation of a function-bearing system as a causal necessity for its constituent parts, functional explanation references distinct and irreducible holistic properties. Using Kantian metaphysics to frame the discussion, this thesis aims first to explore critically the subject of functional characterisations of biological phenomena, and second, the metaphysical basis of modern science. Its chief contributions to the philosophical function debate reside in proposing novel arguments in justification of what I consider is an improved formulation of an attempted definition of biological function, in which teleological causal powers are explicitly recognised and accommodated in functional explanation. Moreover, this thesis attempts a naturalistic reconstruction of the metaphysical entailments of the real causality of a whole

- Description: Tuberculosis (TB) is a multi-organ infection caused by rod-shaped acid-fast Mycobacterium tuberculosis. The World Health Organization (WHO) ranks TB among the top 10 fatal infections and the leading the cause of death from a single infection. In 2017, TB was responsible for an estimated 1.3 million deaths among both the HIV negative and positive populations worldwide (WHO, 2018). Approximately 23% (roughly 1.7 billion) of the world’s population is estimated to have latent TB with a high risk of reverting to active TB infection. In 2017, an estimated 558,000 people developed drug resistant TB worldwide with 82% of the cases being multi-drug resistant TB (WHO, 2018). South Africa is ranked among the 30 high TB burdened countries with a TB incidence of 322,000 cases in 2017 accounting for 3% of the world’s TB cases. TB is curable and is clinically managed through a combination of intensive and continuation phases of first-line drugs (isoniazid, rifampicin, ethambutol, and pyrazinamide). Second-line drugs which include fluoroquinolones, injectable aminoglycoside and injectable polypeptides are used in cases of first line drug resistance. The third-line drugs include amoxicillin, clofazimine, linezolid and imipenem. These have variable but unproven efficacy to TB and are the last resort in cases of total drug resistance (Jilani et al., 2019). TB drug resistance to first-line drugs especially isoniazid in M. tuberculosis has been attributed to single nucleotide polymorphisms (SNPs) in the catalase peroxidase enzyme (katG), a protein important in the activation of the pro-drug isoniazid. The SNPs especially at position 315 of the katG enzyme are believed to reduce the sensitivity of the M. tuberculosis to isoniazid while still maintaining the enzyme’s catalytic activity - a mechanism not completely understood. KatG protein is important for protecting the bacteria from hydro peroxides and hydroxyl radicals present in an aerobic environment. This study focused on understanding the mechanism of isoniazid drug resistance in M. tuberculosis as a result of high confidence mutations in the katG through modelling the enzyme with its respective variants, performing MD simulations to explore the protein behaviour, calculating the dynamic residue network analysis (DRN) of the variants in respect to the wild type katG and finally performing alanine scanning. From the MD simulations, it was observed that the high confidence mutations i.e. S140R, S140N, G279D, G285D, S315T, S315I, S315R, S315N, G316D, S457I and G593D were not only reducing the backbone flexibility of the protein but also reducing the protein’s conformational variation and space. All the variant protein structures were observed to be more compact compared to the wild type. Residue fluctuation results indicated reduced residue flexibility across all variants in the loop region (position 26-110) responsible for katG dimerization. In addition, mutation S315T is believed to reduce the size of the active site access channel in the protein. From the DRN data, residues in the interface region between the N and C-terminal domains were observed to gain importance in the variants irrespective of the mutation location indicating an allosteric effect of the mutations on the interface region. Alanine scanning results established that residue Leucine at position 48 was not only important in the protein communication but also a destabilizing residue across all the variants. The study not only demonstrated change in the protein behaviour but also showed allosteric effect of the mutations in the katG protein.

- Description: This thesis is concerned with the crisis of xenophobia in South Africa. It argues, firstly, that xenophobia itself is not primarily a reaction to poverty, inequality, or any other set of social conditions. Rather, xenophobia must be considered to be a collective political discourse which has arisen in post-apartheid South Africa from an exclusionary conception of state nationalism. Where this work may be distinguished from the majority of research on xenophobia in South Africa is in the fact that its particular focus is on instances where ‘ordinary’ South Africans have challenged and resisted xenophobic violence in their communities through collective political mobilisation. I suggest that these sites of resistance deserve careful consideration in their own right. I argue that they may demonstrate a subjective break with the oppressive politics of state nationalism through the affirmation of alternative political conceptions. Drawing on the political theory of Sylvain Lazarus, and his principal thesis that people are capable of thinking politics in ways which can subjectively think beyond the social and the extant (underscored by his political and methodological axiom, people think), this thesis argues that these sites of resistance show that people – and especially those who are considered to be marginalised from the domain of legitimate politics – can and do think politically, and it is in the thought of people that new and potentially emancipatory visions of politics may emerge.

Understanding the links between smallholder farmers and retailers of meat and vegetables in Mthatha, Mqanduli, Port St Johns and Tsolo, Eastern Cape, South Africa

- Description: It is commonly accepted that one of the challenges faced by smallholder farmers is lack of ‘access to markets’. This is especially so against the backdrop of the supermarket revolution, which is widely understood to give advantage to large-scale farmers at the expense of smallholder farmers. Given that supermarkets are now well established even within South Africa’s former homelands, it would seem that even smallholders based in these areas are at a disadvantage. The purpose of this study is to delve deeply into the market access of smallholder farmers, and to do so specifically across a large area of the former Transkei where supermarkets are well established and where there are also a range of other types of retailers. The study seeks to understand the links between smallholder farmers and diverse kinds of food retailers of meat and vegetables in and around the towns of Mthatha, Mqanduli, Port St Johns and Tsolo in the Eastern Cape Province, South Africa. For each of these sites, the study estimates the share of purchased fresh vegetables and meat that ultimately originates from smallholder farmers within the former Transkei, as opposed to large-scale farmers further afield. The findings suggest that smallholder farmers account for about 24% to 40% of fresh vegetables, and 3% to 13% of meat. The difference between vegetables and meat seems to relate to the fact that smallholder farmers account for a reasonably large share of the fresh vegetables sold by at least some supermarkets, whereas smallholder livestock farmers are largely unable to sell to abattoirs, whether because of the standards imposed by these abattoirs (including the one in Mthatha), or because of the cost of transport. The differences between sites appear to be a function of several factors, including differential market size and resource endowments. The study further sought to identify the advantages and disadvantages that the different types of retailers experience in procuring from smallholder farmers, and also identify the advantages and disadvantages that smallholder farmers experience in supplying different types of retailers. The advantage of working with smallholder farmers is that smallholder farmers can even deliver on Sundays, unlike other suppliers that refuse to work during weekends. The disadvantage is that smallholder farmers are not producing consistently therefore it is hard to rely on smallholder farmers for supply of produce. The advantage that smallholder farmers experience in supplying different types of retailers is that they get their cash right away after delivering the produce. The challenge that smallholder farmers experience when supplying food retailers is that some of the supermarkets will see the sample and order large quantity, however on the day of delivery they will complain and say it is not the good quality so the farmers must reduce the selling price. The study suggests the strategy that could be used by farmers to access the market, which is to enhance knowledge of market skills and negotiation skills.

- Description: Traditionally, coastal communities along the Wild Coast in the Eastern Cape, used mangrove forests for their livelihoods and socio-economic needs. Mangroves along the Eastern Cape coast are threatened by both natural and human factors. The wood obtained from the mangroves by rural households was used as poles for house and fence construction, firewood, and traditional medicine. This is a threat to the status of several mangrove species in this and surrounding areas. The harvesting of mangrove trees will have a direct and indirect effect on the other biotic and abiotic components of the mangrove ecosystems. The Department of Agriculture, Forestry and Fisheries (DAFF) (currently the Department of Environment, Forestry and Fisheries, or DEFF), through the National Forest Act no 84 of 1998, was directly responsible for the wellbeing of the national forests in South Africa. This also includes the mangroves as a specific national forest type. Several estuaries with mangroves occur within state forests. The harvesting and clear-felling of trees for timber and land conversion and associated waste of harvested mangrove poles and laths causes the many changes in mangrove forests. The aim of this study was to develop a framework for sustainable management of the mangroves for the Mtambalala forest management unit. This was done in relation to the requirements of the current legislation, policy guidelines and business plan of the management authority. The aim was pursued through two specific objectives. The first objective was to understand the variation in the composition in different parts of the Ntafufu Estuary, and the population dynamics of the main mangrove species, as basis for the development of sustainable resource use practices. Plots along transects were used to measure seedling to adult ratios, population structure and abiotic characteristics. The second objective was to understand the community use and requirements of mangrove wood from the Ntafufu Estuary. A participatory approach was followed to collect demographic data from each community, the requirements of mangrove poles and behaviour of harvesters. This was used to set up a framework to guide the sustainable management of mangroves based on the current status and stand dynamics of the mangrove communities. There are three mangrove species found in the Ntafufu Estuary: Bruguiera gymnorhiza (black mangrove) regenerates under the mangrove canopy and forms layers of even-aged stands. Avicennia marina (white mangrove) does not regenerate under a mangrove canopy i.e. the seedlings establish outside the canopy. A few Rhizophora mucronata (red mangrove) trees exist in the lower intertidal zone and form multiple stems on stilt roots. The mangrove associate, Hibiscus tiliaceus (wild cotton tree- mangrove associate), forms dense clusters of scrambling stems. Some of the Avicennia individuals show signs of mangrove bleeding and one individual of Bruguiera showed indications of disease. Mngazana and Ntafufu Estuaries had the highest tree densities of 2594 and 1402 trees ha-1 respectively, typical of riverine mangrove forest. The seedling to adult ratio was high in this study: 12.8 for B. gymnorrhiza and 24.3 for A. marina. Abandoned cut stems and laths were found during the study. Bark harvested for traditional medicine and cattle feeding in mangroves was also prevalent and expected to reduce the health of the forest. Mangroves in the Ntafufu Estuary are expanding, and the population structure of the three mangrove species showed a healthy balance between young and mature stems. The harvesting of Black mangrove (B. gymnorrhiza) poles for mainly roof construction is relatively limited. As part of the functions of the DAFF, the use of the mangrove resources has to be balanced with the resource availability from the mangroves, and this should result in a healthy functioning mangrove forest. Development of a participatory forest management (PFM) plan for a forest estate and its forest management unit, require an understanding of the mangrove communities and their dynamics, and the current level of resource use associated with the mangroves. The study recommended that a Mangrove Pole Harvesters Group is needed to practice silviculture through guidance of relevant governmental personnel.
