- Description: This study makes a contribution to the field of sustainable agricultural development and women empowerment in rural South Africa by examining the transformations derived from an expansive learning process with a women farmers group in terms of their food production capability expansion and empowerment as well as the well-being of their local catchment or landscape where their activity was situated. The study took place in the Lutengele villages along the upper reaches of the lower Mzimvubu Catchment near Port St Johns in the Eastern Cape province of South Africa. Women in southern Africa are significant contributors to household livelihoods through their household food production practices and at the same time they are also one of the primary natural resource users in rural landscapes. In this case study, historical and contemporary ethnographic and situational data revealed disjuncture between existing practice and the fulfilment of women aspirations with regard to food security and social and ecological well-being at large. As a result, central to this study were the concepts of aspirations and capabilities and the role that these played in transformative learning processes via formative intervention research (after Engeström’s concept of expansive learning). Expansive learning emerges from Vygotsky’s early work on mediation of learning through language and culture, which gave raise to Cultural Historical Activity Theory (CHAT). Whereas the Capability Approach (CA) recognises that development interventions or initiatives should focus on “expanding the freedom that deprive people from enjoying their valued beings and doings” (Sen, 1999, p. 3), in other words, what people value or have reason to value. The Capability Approach coupled with CHAT deepens the contextual understanding of the agricultural activity system in light of the engendered power dynamics associated with women having access to productive resources, their culturally expected roles and responsibilities in the institution of their households, their families and the community at large, and most importantly, aspects of gerontocracy defined by their age and status in society. In addition, drawing on the Capability Approach as a lens to view agricultural development, social transformation and empowerment, provided the tools to conceptualise participants’ aspirations, their true value and the capabilities necessary for such aspirations to be realised in a context filled with socio-cultural and political power relations and dynamics faced especially by women. The first phase of the study set out to map the context in which the participants’ small-scale food production activity was situated, their aspirations relevant to sustainable agricultural livelihoods, food security, well-being and lastly, the main factors or contradictions inhibiting participants from attaining the aspired food production goals. During the initial phase of the expansive learning cycle I was able to address the first research question: What tensions and contradictions in aspiration-practice relationships shape household food security in the context of catchment management of the women farmers’ group or river forum in the Lutengele area? Twelve contradictions were identified from the historical and contemporary socio-cultural analysis of the home-based food production practices and agricultural activity in relation to the research participants’ envisaged aspirations, which under further scrutiny were thereafter considered by the participants as critical capabilities to pursue during the collective and transformative learning process in the second phase of the study. In the second phase of the study, a series of second stimuli were introduced in the form of conceptual and material tools and tasks with the aim to move participants along the expansive learning process. This led to the unfolding of the collectively defined Capability Learning Pathways for sustainable food production or expansion of their agricultural capability in the context of sustainability of the local micro-catchment or landscape. Through the various Change Laboratory workshops and supporting mini-cycles in the last stages of the formative interventionist research, participants’ learning and development was supported in a way that not only brought individuals together to co-design relevant solutions, strategies and working groups or committees, but also catalysed and amplified transformative agency and the expansion of food production capability, sustainable land use practices and ultimately empowerment. This answered the second and most important research question: Can, and if so, how can expansive social learning processes shape conversion factors for turning available resources into functionings that enhance household food security capabilities and ecological well-being? The methodology of expansive learning and formative interventionist research design intervention, with supporting mediating tools, has proven a positive intervention in the attainment of capabilities (or functionings) in relation to the participant’s aspired livelihoods and consequently improving their well-being as well as their ability to navigate through the various gendered power dynamics, especially for the young women participating in this study. The study proposes expansive learning as a suitable critical and transformative learning theory and methodology for the mediation of collective deliberations and the pursuit of capability development as charted by the learners’ collective and individual aspirations. This is a learning process that not only pursues the learners’ attainment of material and cognitive changes but also opens up new opportunities and most importantly, the freedom to exercise their agency no matter the circumstances they find themselves in – in other words, the freedom to aspire and to be, do and become what one values as instrumentally and intrinsically critical to live a life that they have reason to value. In sum, the unfolding of the expansive learning process happened at three levels: at the value clarification level in terms of human and non-human relationships and social relationality, the institutional level and the practices level. The study recommends further research on the suitability of expansive learning and Change Laboratories as a Capability Expansion Methodology involving human development and Capability Approach practitioners, particularly those with an interest in informal learning and community-based empowering initiatives. Additionally, further studies are also suggested for examining formative interventionist research as a participatory action research approach for capability development work in education and learning research and in different study fields and contexts. , Thesis (PhD) -- Faculty of Education, Education, 2022

- Description: COVID-19, as a disease resulting from SARS-CoV-2 infection, and a pandemic has had a devastating effect on the world. There are limited effective measures that control the spread and treatment of COVID-19 illness. The homodimeric cysteine main protease (Mpro) is crucial to the life cycle of the virus, as it cleaves the large polyproteins 1a and 1ab into matured, functional non-structural proteins. The Mpro exhibits high degrees of conservation in sequence, structure and specificity across coronavirus species, making it an ideal drug target. The Mpro substrate-binding profiles remain, despite the resolution of its recognition sequence and cleavage points (Leu-Gln↓(Ser/Ala/Gly)). In this study, a series of hexapeptide sequences containing the appropriate recognition sequence and cleavage points were generated and screened against the Mpro to study these binding profiles, and to further be the basis for efficiency-driven drug design. A multi-conformer hexapeptide substrate library comprising optimised 81000 models of 810 unique sequences was generated using RDKit within the context of python. Terminal capping with ACE and NMe was effected using SMILES and SMARTS matching. Multiple hexapeptides were complexed with chain B of crystallographic Mpro (PDS ID: 6XHM), following the validation of chain B for this purpose using AutoDock Vina at high levels of exhaustiveness (480). The resulting Vina scores ranged between -8.7 and -7.0 kcal.mol-1, and the reproducibility of best poses was validated through redocking. Ligand efficiency indices were calculated to identify substrate residues with high binding efficiency at their respective positions, revealing Val (P3), Ala (P1′); and Gly and Ala (P2′ and P3′) as leading efficient binders. Binding efficiencies were lowered by molecular weight. Substrate recognition was assessed by mapping of binding subsites, and Mpro specificity was evaluated through the resolution of intermolecular interaction at the binding interface. Molecular dynamics simulations for 20 ns were performed to assess the stability and behaviour of 132 Mpro systems complexed with KLQ*** substrates. Principal component analysis (PCA), was performed to assess II protein motions and conformational changes during the simulations. A strategy was formulated to classify and evaluate relations in the Mpro PCA motions, revealing four main clades of similarity. Similarity within a clade (Group 2) and dissimilarity between clades were confirmed. Trajectory visualisation revealed complex stability, substrate unbinding and dimer dissociation for various Mpro systems. , Thesis (MSc) -- Faculty of Science, Biochemistry and Microbiology, 2022

- Description: Biodiversity forms the basis of the ecosystem services that society depends on. However, humanity has caused an increase in the extinction rates up to 100 times higher than that of evolutionary background levels. Recent studies found that biodiversity conservation becomes successful when it is grounded in local support. Support for conservation of biodiversity depends on peoples’ knowledge of biodiversity, their attitudes and awareness of the number of species that are present and that are threatened with extinction. However, some studies have shown that the public has little knowledge about the concept of biodiversity and have poor biodiversity identification skills. There is growing concern that people know and are more concerned about global biodiversity loss than what is happening around them locally. The notion that people know and are more concerned about global biodiversity loss rather than local, has not been deeply studied. Most studies have been in developed countries, with limited studies in developing countries and countries that have high diversity such as South Africa. Having accurate knowledge about biodiversity and the environment is said to be the key predictor of intention to change behaviour in relation to biodiversity. Therefore, the purpose of this study was to understand the knowledge and concern (if any) people have of biodiversity at global and local scales. More so, it set out to determine how familiar people are with the term biodiversity, what they consider as forces leading to biodiversity decline, the level of concern that they have for biodiversity loss and if knowledge and concern is influenced by demographic profiles. To achieve this aim, a total of 220 random interviews were conducted in three towns within the Maputaland-Pondoland-Albany Hotspot in South Africa. The results show that respondents are familiar with the term biodiversity. There was a strong relationship between having heard of the term and the ability to define it with 55 % of the respondents aware of it and able to define it. Respondents had moderate knowledge general knowledge related to biodiversity. Gender, education and childhood background did play a role in the knowledge of biodiversity. Women had more knowledge about biodiversity than men, highly educated respondents knew more and the youth knew more than older respondents. The results of this study found that there were no respondents who could not name any local species from South Africa. However, things changed at global level with 32 % of the participants unable to name species at global level. Endangered species are still relatively unknown, as the majority of respondents could not name any at district (84 %) or at global level (61 %). Charismatic species were known the most by respondents as 52 % mentioned them at national level and 59 % at global level. This study also assessed if there is concern for biodiversity loss. The results showed that there is concern for biodiversity with 71 % of the respondents in support for conservation and 60 % of the respondents willing to donate towards conservation. This study found that reasons for conservation related to the level of products consumed directly from the environment. Those that supported conservation for use values consumed more products from the environment than those who were in support for non-use values. Furtherly, this study found that women were more concerned about biodiversity loss than men. Highly educated respondents were more concerned and the youth was not. Furtherly, this study found that knowledge about biodiversity loss corelated with concern. For example, women had more knowledge and were more concerned about biodiversity loss. Overall, this study has shown that there is some knowledge and concern that people have about biodiversity and its loss. This can assist the relevant policy makers and researchers to know where intervention is needed to increase the knowledge that people have of biodiversity loss and which aspects of biodiversity people are most concerned about. This is so that new policies and conservation measures can include what is appealing to the local people so that support for conservation can be built and accepted by local people. , Thesis (MSc) -- Faculty of Science, Environmental Science, 2022

- Description: Land degradation is a global phenomenon which is having serious negative consequences for rural livelihoods, which depend quite fundamentally on land and its resources. At the same time, one of the key conditions contributing to land degradation relates to rural livelihood practices, insofar as these practices fail to protect the land. Hence, there sometimes exists a mutually-reinforcing process of decline, in relation to both land vitality and livelihoods vitality over time. This thesis seeks to investigate and understand this complex land-livelihoods process through a case study of two fast track farms in the Shurugwi District of contemporary Zimbabwe. In the year 2000, the Zimbabwean government introduced the fast track land reform programme which fundamentally reconfigured the rural landscape. In particular, it led to the formation of A1 farms (containing small-scale farming units called A1 plots), onto which people were resettled for purposes of enhancing their livelihoods. The case study focuses on two A1 farms in the district, namely, Selukwe Peak and Adare farms. Through a longitudinal study of land and livelihoods on these A1 farms, this study seeks to identify the multi-faceted character of land degradation on the farms, the multi-layered conditions (or causes) facilitating land degradation (specifically, the farm-based livelihood practices) and the effects of this land degradation on these very livelihood practices. This includes a focus on farmers’ understandings of land degradation and how these understandings may or may not condition livelihood practices on the two farms. Of particular importance is the presence of not only agricultural practices, but also high levels of illegal and legal mining on the farms and in the surrounding areas. In pursuing this study, the thesis draws upon the Sustainable Livelihoods Approach alongside Margaret Archer’s morphogenetic sociological perspective. Combined, they provide an intricate understanding of the relevance of both structure and agency to the analysis. A qualitative methodology was used, and this involved a questionnaire survey, in- depth interviews, life histories, focus group discussions and transect walks. The study concludes that the livelihood strategies undertaken by the villagers of Selukwe Peak and Adare farms are key causes of land degradation, as are the land-degrading activities of illegal and legal miners. The A1 villagers are aware that their activities are causing land degradation but they continue these activities because they are pushed by circumstances beyond their control. Hence, both proximate and underlying causes are of some significance in understanding land degradation and livelihoods on the two farms, and their interrelationships. , Thesis (PhD) -- Faculty of Humanities, Sociology, 2022

- Description: Coastal habitats, and more specifically, intertidal habitats, host a unique range of biodiversity and are key areas for many fish and invertebrate species across one or more of their life stages. This is due to the provision of microhabitats which offer an escape from harsh environmental stressors and predation as well as increased food supply, hence increasing chances of survival. Due to the growing human population however, coastal habitats are being replaced by artificial structures (jetties, seawalls, piers, breakwaters) which partially or heavily fragment the natural environment through urbanisation-related expansion processes. These coastal infrastructures also have different physical properties from the natural environment and therefore tend to support different biological assemblages and can potentially alter the existing biodiversity and its functionality. The overall aim of this project was therefore to evaluate the use of artificial and natural intertidal microhabitats by fish and invertebrate larvae along the South African, Eastern Cape coastline. As independent case studies, fieldwork was conducted at an urban (Port Alfred Marina) and rocky shore (Kenton-on-Sea) site. Within each of these study sites, two replicated sheltered subsites were selected, which represented microhabitats. Samples were collected from these replicated microhabitats from September 2019 to February 2020 using light traps which targeted phototactic larval species, as well as a portable pump, for photo-neutral/negative taxa. All samples were preserved onsite in 99% ethanol and specimens were later counted and identified in the laboratory to the lowest possible taxonomic level using a stereomicroscope. Additionally, DNA barcoding was conducted on selected larval taxa for verification of morphological identification as well as contributing to the field of larval taxonomy through development of public database records. The barcoding technique was effective in positively identifying 96% and 58% of fish and invertebrate larvae sampled, respectively (overall identification success of 86%), to either family, genus or species level. Results of microhabitat use indicate higher larval abundances associated with artificial structures as compared to natural structures, with significant differences between the selected microhabitats within the rocky shores and the marina respectively, across months. High numbers of several early stage taxa were observed within the selected microhabitats in the marina, with Pinnotheres sp. (zoea) (Family: Pinnotheridae) being the most abundant invertebrate larval taxon collected at the artificial microhabitats of jetties and vertical walls. Fish larvae of Omobranchus woodi (preflexion) and Etrumeus whiteheadi (postflexion) were the most dominant at the selected artificial microhabitats within the marina. The DNA barcoding tool used in the current study to verify morphological identification proved to be instrumental in the accuracy of the reliable data collection of the early life stages present in these habitats. These results suggest that artificial structures may provide refugia for the vulnerable very early life stages of species and, in turn, play a potential facilitative role in reproductive and population connectivity which could result in replenishment of natural populations. It is therefore possible that these urban habitats could be considered as hubs for maintenance of coastal biodiversity. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2022

- Description: Giant kingfish Caranx ignobilis, the largest species in the family Carangidae, are global icons as apex marine predators. They are widespread in tropical to subtropical regions globally, where they are of high importance to ecosystems and fisheries. During summer, adults aggregate for spawning, making them vulnerable to overfishing. The world’s largest recorded C. ignobilis aggregation is in southern Mozambique. Some of these aggregating individuals (an unknown proportion) have been recorded passing into South African waters. Furthermore, a unique aggregation of adult C. ignobilis in South Africa’s Mtentu Estuary has attracted global attention but remains unexplained, hence warranting investigation. Research on C. ignobilis globally has shown relatively small home ranges. Research in southern Africa has been limited and inconclusive. Thus, the broad aim of this study is to describe the movement patterns of C. ignobilis from southern Africa. Long-term (36 years) mark-recapture data from the Oceanographic Research Institute’s Co-operative Fish Tagging Project, comprising 3 729 tagged C. ignobilis and 144 recaptures, were analysed. While 74% of recaptures were recorded < 1 km from the tagging location, long-distance movements of up to 419 km were also recorded (mean = 15 km). Although adults moved significantly (p < 0.01) greater distances than juveniles, they also displayed high levels of site fidelity. Seasonal trends included evidence of a summer migration; however, there was still considerable uncertainty regarding exact movements. Therefore, 43 C. ignobilis were acoustically tagged and subsequently monitored along the east coast for over five years with the Acoustic Tracking Array Platform’s passive receiver array. All acoustically tagged adult C. ignobilis migrated to southern Mozambique each year (with minor exceptions), from distances of up to 632 km. When not migrating, South African-based fish showed consistent inter-annual fidelity to individual home ranges. Although coastal home range length (excluding migrations) varied considerably between individuals, even the mean length (92 km) was greater than any previously recorded C. ignobilis home range, globally. In contrast to the southern Mozambique aggregation, the Mtentu Estuary aggregation seems to comprise of individuals showing fidelity to that region. The passive tracking of eight acoustically tagged individuals in the Mtentu Estuary revealed clear trends. Statistical modelling showed that estuarine presence was strongly associated with periods of cold coastal upwelling. Diel movement patterns showed that the utilisation of warm surface waters ~ 4 km upstream during the day was followed by nightly departures to the mouth or sea. Thus, it is likely that this majestic aggregation is for thermal refuge; specifically, for daily re-warming after feeding in cold waters at night. Findings from this study are of global ecological interest and have direct applications for local fisheries management and the development of sustainable eco-tourism. Protecting these vulnerable aggregations is of the utmost importance for the future of this species in southern Africa. , Thesis (MSc) -- Faculty of Science, Ichthyology and Fisheries Science, 2022

- Description: South Africa, as a post-apartheid state is still grappling with socio-economic inequalities such as poverty, unemployment, and inequality. Local government is mandated to play a developmental role and has a responsibility to redress these socio-economic inequalities at grassroots level. According to the Constitution of South Africa, the local government sphere is obligated to adopt and practice good governance. Whilst good governance means different things to different people, this study argues that good governance is characterised by transparency and accountability, and the use of public resources in an accountable and sustainable manner in order to ensure the progressive realisation of the needs of the municipal residents. This study explores the relationship between oversight and service delivery by examining the Municipal Public Accounts Committee’s oversight of electricity services in Raymond Mhlaba Municipality (herein referred to as RMM) in South Africa’s Eastern Cape Province. It makes use of a case-study research design to inform its data collection and analysis. Officials responsible for electricity service provision and councillors responsible for overseeing the performance of electricity services in RMM were interviewed. These interviews were analysed together with a document analysis of RMM, and a review of relevant local government legislation. The research findings indicate that the Municipal Public Accounts Committee (herein referred to as the MPAC) in RMM failed to engage in effective oversight due to (1) a lack of familiarity with the municipality’s plans for electricity services, (2) a lack of familiarity with the targets for revenue collection and expenditure management for electricity services, and (3) a lack of rigorous oversight and monitoring of the municipality’s spending and implementation of targets set out in its electricity plans. This study, therefore, reflects the realities of non-effective oversight in municipalities in the Eastern Cape and proposes a model which can improve some of the dire oversight practices which are prevalent in rural municipalities such as RMM. , Thesis (MSocSci) -- Faculty of Humanities, Sociology, 2022

- Description: Nearly every philosopher in English-speaking world has heard of Ockham’s Razor, which is given in one of two ways, don’t multiply entities beyond necessity and all things being equal choose the simpler explanation. Yet it is unclear from the scholarship whether the use of Ockham’s Razor is justified in science and philosophy. However, if it can be shown to ‘get’ us truth, it would gain an unequivocal justification, as disputes that are continued after the parties to the substantive truth of one or the other are defined as frivolous. Alternative, one may contend that explanation could have other criteria of success. The implication of a direct connection between the razor and truth comes with ontological commitments, namely a commitment to realism (about universals) and philosophical theism. This is contrary to the razor’s use as a tool of nominalism and naturalism. I argue in this thesis there that the only possible non-circular justification for Ockham’s Razor is truth and that therefore certain philosophical positions are excluded from using the razor to animate their positions. There is an additional, second criteria for the success of our inquiry, namely the justification must in some way be consistent with the razor, which means the chosen explanation for the razor, must be simpler than any of its rivals and not have superfluous entities, otherwise our justification would be contrary to the advice of the razor. We are presented with a Scylla and Charybdis type problem, we avoid a circularity on the one hand and on the other we must not contradict the razor itself, these are contrary intellectual impulses. So firstly I will look at disciplines outside philosophy for some initial inspiration. If we could answer this question in a ‘non’ philosophical way, the problem would have solved itself in a way that require little change of practice. If lawyers or scientist can account for the razor properly, there is not really a problem of justification, at least not a philosophical one. Second, I consider the realist and theist positions, namely an argument of Aristotle’s in the Posterior Analytics and part of Aquinas’ On the Divine Simplicity. Further, I consider the work of Ockham as a nominalist. Lastly, I consider modern and contemporary philosophy, in the form of Hume, Quine and Sober (a modern writer on the razor). The aim here is to ‘stress test’ the philosophical resources of the various systems and analyse the results to see if they can produce a non-circular result. , Thesis (MA) -- Faculty of Humanities, Philosophy, 2022

- Description: Postal organisations play an important role in the provision of basic communication services. In Zimbabwe, post offices have a large physical distribution network of over 240 post offices country-wide to make communication services accessible to the populace. However, e-substitution has threatened mail business significantly. Postal operators globally are experiencing declining mail volumes in the face of advanced information and communication technologies. The overall goal of this thesis was to undertake a socio-historical analysis of organisational change at ZimPost using Taylorism, Fordism and post-Fordism as broad ideal types to explain how industry evolves in different phases of capitalism. National politics and economics play an integral role in how Taylorism, Fordism and post-Fordism assumed at ZimPost. Studies on these broad organising types have mainly focused on private sector organisations. However, this thesis argues that these analytical paradigms are also valid in public sector organisations, but they will unfold differently given the context in which change is experienced. Using a qualitative approach, the study established that the 1980s and 1990s can best be described as the ‘golden years’ of postal services in Zimbabwe, characterised by mass production and mass consumption of postal products and services. At that time the Posts and Telecommunications Corporation enjoyed a monopoly of postal services in the country. The stable market share, competitive salaries for postal workers, increased unionisation and a fairly stable economy enabled a Fordist regime of accumulation to develop. The cycle broke down when the mode of regulation was weakened by national economic and political changes towards the late 1990s. PTC started to experience a decline in the consumption of postal products. The decline was also attributed to increased competition from smaller private courier operators that could provide specialised services to a market with changing needs. With increased competition, the advancement of information, and communication technologies, mail volumes dwindled. This period can best be described as the crisis of Fordism at ZimPost. In the year 2000, the government unbundled the posts and telecommunications corporation to create four companies including Zimbabwe Posts. This was perceived as one of the most radical organisational changes in the history of postal services in Zimbabwe. More organisational changes took place at ZimPost that can best be described as characteristics of post-Fordism. These changes were attempts by ZimPost to remain relevant in light of the economic, political and technological changes taking place in the country. The postal operator introduced customised products in the form of agency services, supported by increased use of information and communication technologies in the post office. Organisational changes at ZimPost were shaped mainly by the economic and political environment in which they took place. Organisational change is complex, changes do not follow a linear pattern, they are processual. , Thesis (PhD) -- Faculty of Humanities, Sociology, 2022

In Zimbabwe, post offices have a large physical distribution network of over 240 post offices country-wide to make communication services accessible to the populace. However, e-substitution has threatened mail business significantly. Postal operators globally are experiencing declining mail volumes in the face of advanced information and communication technologies. The overall goal of this thesis was to undertake a socio-historical analysis of organisational change at ZimPost using Taylorism, Fordism and post-Fordism as broad ideal types to explain how industry evolves in different phases of capitalism. National politics and economics play an integral role in how Taylorism, Fordism and post-Fordism assumed at ZimPost. Studies on these broad organising types have mainly focused on private sector organisations. However, this thesis argues that these analytical paradigms are also valid in public sector organisations, but they will unfold differently given the context in which change is experienced. Using a qualitative approach, the study established that the 1980s and 1990s can best be described as the ‘golden years’ of postal services in Zimbabwe, characterised by mass production and mass consumption of postal products and services. At that time the Posts and Telecommunications Corporation enjoyed a monopoly of postal services in the country. The stable market share, competitive salaries for postal workers, increased unionisation and a fairly stable economy enabled a Fordist regime of accumulation to develop. The cycle broke down when the mode of regulation was weakened by national economic and political changes towards the late 1990s. PTC started to experience a decline in the consumption of postal products. The decline was also attributed to increased competition from smaller private courier operators that could provide specialised services to a market with changing needs. With increased competition, the advancement of information, and communication technologies, mail volumes dwindled. This period can best be described as the crisis of Fordism at ZimPost. In the year 2000, the government unbundled the posts and telecommunications corporation to create four companies including Zimbabwe Posts. This was perceived as one of the most radical organisational changes in the history of postal services in Zimbabwe. More organisational changes took place at ZimPost that can best be described as characteristics of post-Fordism. These changes were attempts by ZimPost to remain relevant in light of the economic, political and technological changes taking place in the country. The postal operator introduced customised products in the form of agency services, supported by increased use of information and communication technologies in the post office. Organisational changes at ZimPost were shaped mainly by the economic and political environment in which they took place. Organisational change is complex, changes do not follow a linear pattern, they are processual. , Thesis (PhD) -- Faculty of Humanities, Sociology, 2023

- Description: The field of supramolecular chemistry has grown large and wide in both deepness of understanding, range of topics covered and scope and applications. Supramolecular self-assemblies are facilitated by a wide range of non-covalent intra and inter molecular interactions that range from hydrogen bonding to π-interaction and van der Waals. Macrocyclic compounds such as cucurbiturils and calixarenes have emerged as important classes of compounds with excellent potential of forming supramolecular assemblies. The porous nature of these compounds enables them to form host-guest supramolecular complexes stabilized by diverse range of non-covalent interactions. Furthermore, these compounds contain donor atoms capable of forming bonds with metal ions to yield metal complexes with interesting porous characteristics that deviate from their traditional hydrophobic cavity. The versatile nature of the resulting pores imply that they can accommodate diverse types of guests. This work explores the synthesis and characterization of a host of calixarenes and cucurbiturils. Self-assembly of these macrocycles with various metal ions results to the formation of porous metal organic framework (MOF) complexes. Four new calixarene typed compounds obtained from aromatic aldehydes and twenty-six cucurbituril metal complexes are reported. These macrocylces and their metal complexes also form supramolecular complexes with DMSO, methanol, isoniazid hydrochloride and ciprofloxacin hydrochlorides through either self-assembly, mechanochemistry and exposure to solvent vapors. The bulk materials have been characterized using nuclear magnetic resonance spectroscopy (NMR), Fourier transformed infrared spectroscopy (FTIR), powder and single crystal diffraction techniques and thermal studies thermogravimetric analysis (TGA) and differential thermal calorimetry (DSC). Data obtained from this study reveals that calixarenes can form supramolecular complexes with a frequently used laboratory solvents with BN22 showing appreciable selectivity for DMSO sorption from a solvent mixture. These compounds also form supramolecular complexes with drug molecules such as isoniazid and ciprofloxacin. Furthermore, the data reveals that choice of synthetic route of supramolecular ensembles dictates if the guest drug molecule will occupy the intrinsic or extrinsic pores of cucurbituril complexes. Biological studies on the obtained complexes reveal that the cucurbituril complexes are non-cytotoxic while the calixarenes show antibacterial activity against Escherichia coli and Staphylococcus aureus. Additionally, the study showed that ciprofloxacin can be successfully released from a calixarene host in a simulated body fluid although the host was also found to cross the dialysis membrane. The results of this study are important in that; - they can be exploited and developed in the selective sorption of certain guests and - that they can be used in the development of drug delivery systems that play a dual role of delivery and therapeutic activity. , Thesis (PhD) -- Faculty of Science, Chemistry, 2022

- Description: Mozambique tilapia, Oreochromis mossambicus, a native southern African species now co-occurs with invasive Nile tilapia, Oreochromis niloticus throughout much of the distribution of the former. The spread of O. niloticus in South Africa has been attributed to escapees from aquaculture facilities, placing O. mossambicus at risk through competition for habitat and food resources, as well as through hybridisation. To better manage invasions, a comprehensive understanding of the biology, ecology and behaviour of both native and invasive species is required. The aim of this research was to comparatively assess the biology of O. mossambicus and O. niloticus, their food resource use characteristics and potential competitive interactions to infer impact risks associated with O. niloticus invasion dynamics. In addition to lack of sufficient autecological knowledge on O. niloticus in general, the challenge in the Eastern Cape is that relatively little regional knowledge is available on the biology and ecology of the native O. mossambicus. To address this, a total of 101 O. mossambicus individuals (32 - 297 mm LT) were sampled from the Sunday River catchment and their age and growth determined using sectioned sagittal otoliths. The largest female was 288.8 mm with a parameter estimate of LT (mm) = 272 (1-e-0.331(t=0.772)) and the largest male was 297 mm described as LT (mm) = 331.9 (1-e-0.167(t=1.192)). The growth parameter estimate age for combined sexes was best described as LT (mm) = 322.5 (1-e-0.201(t=1.027)). The growth rate was initially rapid for O. mossambicus and the asymptotic length reached after four years. The length-at-50% maturity was reached at 106.45 mm LT (R2 = 0.57) for the entire population. There was a significant difference (ᵡ2 = 8,047, df = 1, p-value = 0.0045) in the sex ratio between males and females which was skewed towards males 1:1.89 (F:M). Comparisons with O. niloticus were based on literature and these showed that O. niloticus had faster growth rates than O. mossambicus. These results serve as a baseline study in predicting the potential impacts of O. niloticus if it was to be introduced in the Eastern Cape region. Furthermore, although these two species are known to share habitat and food resources, feeding dynamics within the context of relative impact on prey resources, and competition potential between the species, are largely lacking. I used experimental functional response procedures to contrast the food consumption dynamics of each species and to assess for any multiple predator effects (MPEs) between these two closely related fishes. This was done by contrasting functional responses between individual species under single predator scenarios, predicted multiple predator functional response dynamics based on the individual species outputs, and actually observed functional responses under multiple predator conditions. Results showed that both Nile tilapia and Mozambique tilapia depicted a destabilizing Type II functional response. In both single and conspecific pairing Nile tilapia had significantly greater functional responses than Mozambique tilapia, hence greater overall predatory potential than its native congeneric Mozambique tilapia. Attack rates were also greater for Nile tilapia than Mozambique tilapia with both species showing similar handling times in single trials. However, no evidence for MPEs were detected, given lack of differences between predicted and observed functional responses under heterospecific conditions. These results suggest that Nile tilapia do not adjust their food intake in the presence of heterospecific competitors, but do consume more than Mozambique tilapia and are better at finding food when it is present at low densities. Feeding-related morphological characteristics may influence predatory performance of a species and can further provide information on the species’ capacity to locate, attack and consume different prey items. The feeding capacities between O. mossambicus and O. niloticus were compared based on morphological traits in order to determine whether differences existed, and if these differences place the invasive O. niloticus at an advantageous position in terms of resource acquisition and consumption over its native congener. Principal component analysis for functional morphology traits showed overlap between O. niloticus and O. mossambicus. Oreochromis niloticus had distinctively larger lower jaw closing force, gill resistance and gill raker length which facilitated greater feeding capacities for the invasive species over the native O. mossambicus. Trophic profiles depicted high dietary overlap between the two species. Although O. niloticus had a greater feeding capacity towards phytoplankton, plants, fish (ambush), fish (pursuit) and larvae, while O. mossambicus only showed greater feeding capacity towards zooplankton. While dietary overlap and similarities in morphological traits between native and invasive species may result in exploitative competition between the species, O. niloticus seems to be more versatile in its feeding and capable of consuming food web components that O. mossambicus may not be able to handle. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2022

- Description: Background: Feedback proves to be a valuable tool in behaviour change as it is said to increase compliance and improve the effectiveness of interventions. Interventions that focus on decreasing sedentary behaviour as an independent factor from physical activity are necessary, especially for office workers who spend most of their day seated. There is insufficient knowledge regarding the effectiveness of feedback as a tool to decrease sedentary behaviour. This project implemented a tool that can be used to determine this. To take advantage of the cost-effectiveness and scalability of digital technologies, a mobile application was selected as the mode of delivery. Method: The application was designed as an intervention, using the Theoretical Domains Framework. It was then implemented into a fully functioning application through an agile development process, using Xam- arin.Forms framework. Due to challenges with this framework, a second application was developed using the React Native framework. Pilot studies were used for testing, with the final one consisting of Rhodes University employees. Results: The Xamarin.Forms application proved to be unfeasible; some users experienced fatal errors and crashes. The React Native application worked as desired and produced accurate and consistent step count readings, proving feasible from a functionality standpoint. The agile methodology enabled the developer to focus on implementing and testing one component at a time, which made the development process more manageable. Conclusion: Future work must conduct empirical studies to determine if feedback is an effective tool compared to a control group and which type of feedback (between goal-setting and social comparison) is most effective. , Thesis (MSc) -- Faculty of Science, Computer Science, 2022

- Description: In their efforts for a place in the economy, many South African women have embraced opportunities in the informal sector such as selling products for big Multi-Level Marketers (MLMs), who generally operate on a pyramid structure of commissions. This qualitative study investigates the meanings African women engaged in MLMs in Makhanda make of such work and examines how they construct notions of progress and success through their social media practices. The study was conducted in the strictest lockdown period and pioneered a research method that used Zoom to facilitate screen sharing on mobile phones to create an online version of the scroll-back method for Facebook. As expected for women working in a society increasingly integrated in a global neoliberal order, many of the meanings the women construct are rooted in neoliberal discourses that celebrate hyper-individualism and competition. This firstly includes constructing success through personal stories of self-appreciation, through which these women embody the MLM’s brand, while simultaneously improving their position in the market as sellers. Secondly, the women invest considerable effort on social media in constructing MLM work as epitomising stability in the context of the growing precarity that characterises their everyday lives. However, other meanings draw on the local African context. Here the women make sense of the inequalities that characterise the MLM pyramid structures, by constructing top players in the upline as a symbolic vanguard trailblazing freedom from a racist past through showcasing paths out of poverty. More interestingly, success is constructed as both resulting from and serving collective ways of being rooted in the discourse of African humanism. Here success is recognised as emerging from dense place-based networks in the neighbourhood built on trust and obligation, now replicated on social media. In conclusion, the study speculates that the worlds of meaning facilitated by MLMs might provide ways for neoliberal and traditional discourses to find points of synergy, and so serve as entry points into a neoliberal order that interestingly nevertheless draws on communal cultures of obligation and patronage. , Thesis (MA) -- Faculty of Humanities, School of Journalism and Media Studies, 2022

- Description: Community engagement (CE) is now widely considered a core function of higher education worldwide. In South African higher education institutions (HEIs), there is an increasing focus on CE as a means of transforming the role of the university in society, though the forms and shapes of CE vary by institution. CE is positioned as part of the means of addressing the challenges within the South African education system, such as ensuring equity in academic access in the face of diversity and making sure higher education institutions are responsive to the needs of society. Community Engagement is increasingly being afforded the same status as teaching and learning and research in higher education. The idea that higher education should function as a public good is central to this. This study reflects on how CE can be expansively viewed as places of learning for students to achieve epistemic access with epistemic justice, particularly in increasing diverse and changing contexts. Despite the growing research on CE in HEIs, there is comparatively limited focus on the intersection between CE and language use and potential linkages with identity and epistemic access and success. Given that one of the major challenges in South African HEIs relate to difficulties experienced by students whose home language is not English, the experiences of students learning within CE contexts within those institutions warrants investigation. The main aim of this study was to explore second language English speaking students’ experiences of language in the Engaged Citizen Programme, a Community Engagement programme at Rhodes University aimed at offering students the opportunity of enhanced learning, giving students the opportunity to evaluate the theories and ideas taught in the university against the realities of the South African context. The programme is also intended to offer students the opportunity to learn with and from communities and thereby enable personal growth (ECP Handbook: 2020; p.3). Using an in-depth phenomenological approach, this study explored diverse students’ experiences of language use in both community engaged programmes and in the classroom as a basis for understanding the role language plays in such spaces and the impact of these programmes on epistemic access, justice and success for students in HEIs. The study explored the role that CE plays for second language English students as they navigate complex questions of identity and belonging in HEIs. In CE activities, such as the Engaged Citizen Programme, unlike traditional classroom learning, English is often not the medium of instruction, as learning takes place in community sites, where multiple other languages are spoken. In the traditional classrooms, English is the dominant medium of instruction which can bring challenges for students whose home language is not English. Students are faced with various challenges including failure to communicate effectively and understand content knowledge. Significantly this study found that this often related to a sense of self-worth and belonging and constrained their participation and engagement in class. It was evident from the students’ reflections on their experiences in the Engaged Citizen Programme that CE provided a more flexible space generally more comfortable to these participants; a space that promotes engaged learning without rigid rules. The students’ reflections affirmed the contribution of CE in promoting engagement of students outside the formal classes and enhancing the ways in which they use language freely. It was also evident from the students’ reflections that CE provided a space in which students can identify who they are and have a sense of belonging. In the context of diversity, the majority of the students said they come to the university feeling a level of under preparedness and cannot identity with dominant groups. The reflections from the students’ experiences therefore offer some insights into ways in which we can actively promote CE in supporting student access and addressing issues of epistemic justice in higher education. The findings suggest that many of the benefits of CE, such as higher levels of interaction and significant amounts of translanguaging, need to be brought into the formal classroom spaces because they enhanced student engagement. While CE was also seen to be challenging and there were calls for more support, the essence of the experience was as a space of personal development and awareness of social responsibility. The explicit normative value of CE was in contrast to the absence of such considerations in the formal HE curriculum and the student experiences suggest that much could be learned from this. The use of English, both on campus and in CE activities, was found to be value-laden and politically charged. The participants, black students who spoke English as an additional language, all related experiences of English being positioned as a ‘superior’ language. The students who were highly fluent in English experienced being positioned as ‘showing off’ and seen to have ‘forgotten their roots’. Students who were not highly fluent in English, on the other hand, often constrained their participation in class because they experienced concern that their mispronunciations and accents may be mocked. The essence of the experience of language use in both formal classroom settings and in CE activities is that this is tightly bound to identity and is ideologically fraught. This requires more explicit conversation in all learning spaces. , Kubatirana pamwe nenharaunda (KPN) (CE) iko zvino kwave kutariswa zvakanyanya sembiru yebasa redzidzo yepamusoro pasirese.

- Description: The taxation of informal sector business is increasingly becoming a topical issue in many developing countries, and Zimbabwe is no exception. The Zimbabwean government has been experiencing shrinking revenue in the wake of an increased informal sector and a declining formal sector. In an effort to broaden the tax base and increase revenue for government in Zimbabwe, presumptive tax levied against certain informal sector activities was first introduced in 2005 and later expanded to other sectors. Despite the effort, the informal sector has responded with low tax morale and non-compliance, which creates the need to reassess the current administrative strategies in a bid to build a successful tax system for the informal sector. The main goal of the research is to establish clear, innovative and practical administrative strategies that can be adopted by the Zimbabwe Revenue Authority in taxing the informal sector in Zimbabwe. An initial investigation was done to identify the current state of affairs in relation to informal sector taxation in Zimbabwe. A number of challenges were recorded and the research the sought to learn from examples of recent innovation in administrative strategies successfully applied in taxing the informal sector in other jurisdictions like Tanzania and Ghana. Learning from these examples, a number of practical administrative strategies that are mindful of the Zimbabwean economic context were proposed. , Thesis (MCom) -- Faculty of Commerce, Accounting, 2022

- Description: The rise of Social Networking Sites (SNSs) has raised concerns about the negative impact social media platforms, and in particular Facebook, has on their users. Research has linked the excessive use of Facebook with mental health challenges such as loneliness, depression, and stress. This research examined how Yolanda Dyantyi, a gender rights activist registered as a student from 2015 to 2017 at Rhodes University, used Facebook as an outlet following the #RUreferencelist protests and her subsequent permanent exclusion from the institution for her role in the protests. The study explored Dyanti’s use of Facebook, examining in particular her ongoing activism, her mental health challenges, and her struggles to re-establish herself in a community after the exclusion from Rhodes. The study employed an intersectional feminist theoretical framework and drew on a qualitative content analysis, a semi-structured interview, and the scroll back method to review the Facebook posts she had made. A thematic analysis of the data showed that Dyantyi is a multifaceted, and evolving Facebook user and contrary to existing research her prolific use of Facebook has had positive effects on her mental health and has enabled her to build social capital. The study suggests that activism is an important component to research alongside studies of mental health on such media platforms. , Thesis (MA) -- Faculty of Humanities, School of Journalism and Media Studies, 2022

- Description: International trade plays an essential role in economic development strategies. In literature, foreign trade is identified as a driver of economic growth. In recent times there has been an expansion in the scope of investigations around the role of international trade to include its links with poverty alleviation. Poverty alleviation is explicitly identified as the first goal on the 2030 agenda for sustainable development under the Sustainable Development Goals and implicitly defined in goal 10. International trade is seen as the engine behind achieving the goal. South Africa records excessive poverty and inequality levels by international standards for a middle-income country. The most recent Poverty Trends Report for 2006 - 2015 reports 55.5% of the population living in poverty. Inequality statistics reported a per capita expenditure Gini coefficient of 0.65 in 2015, evidence that the country has high levels of inequality. The country's severe poverty, unemployment, and inequality prompt policymakers to formulate developmental policies around the underlying structural challenges. Trade openness has increased since the end of the Apartheid era. Despite the increased trade openness, economic growth has been insufficient in reducing the high unemployment and poverty levels, presenting a challenge for economists, who argue that trade openness is pro-growth and pro-poor. In the South African case, the lack of change in the structural challenges of poverty, unemployment and inequality has raised concerns over whether the trade policy reforms made since 1994 interfere with development objectives. This study aims to investigate the impact of trade liberalisation on poverty, using the three channels, namely enterprise, distribution, and government that have been researched within the McCulloch, Winters and Cirera framework. Specifically, it investigates the linkages via the transmission mechanism in which trade affects poverty in South Africa by mapping the transmission mechanisms from trade liberalisation to poverty alleviation, whilst identifying the possible challenges to the transmission mechanisms and lastly, analysing the stylised facts around trade and poverty in South Africa. To answer the question of this study, quantitative data from National Income Dynamic Study (NIDS) was merged longitudinally and aggregated with the industry tariff data sourced from the World Trade Organisation (WTO) and United Nations Conference on Trade and Development (UNCTAD) statistics. A path analysis was undertaken to map the transmission mechanism, whilst descriptive statistics were used to identify the possible associated challenges. The results show that the most significant channel of transmission are the enterprise and distribution channel. However, the effects are of a small margin and a more comprehensive trade policy yield a higher margin of poverty alleviation. , Thesis (MCom) -- Faculty of Commerce, Economics and Economic History, 2022
