- Description: Financial inclusion is widely regarded as another conduit through which poverty can be alleviated. However, both theoretical and empirical literature does not reach consensus on the effect of financial inclusion on poverty. Against this background, the study empirically examines the effect of financial inclusion on poverty in selected Southern African Development Community (SADC) countries, which include (Botswana, Malawi, Mauritius, Namibia, South Africa, Tanzania, and Zambia). The author employs the Generalized Method of Moments (GMM) technique for the period 1980 to 2019. Based on the Financial Intermediation Theory and the Social Justice Theory: Tunnel effect, 5 different models were estimated. Variables used to capture the different dimensions of financial inclusion include ATMs per 1000km and Bank Accounts per 1000 adults as well as Bank’s private Credit to GDP and Commercial Bank branches per 1000 adults’. The control variables used in the study are; GDP per Capita, Government Consumption, Inflation and Education. Empirical results revealed that financial inclusion reduces the level of poverty in the selected SADC states. The results also revealed that GDP per capita and government spending have a negative effect on poverty in the region. An interesting finding, even though not the major focus of the study was the effect of education. The results revealed that lower levels of education may exacerbate the level of poverty in the region. At the same time, tertiary education was found to have a negative and significant effect on poverty. The empirical results imply that policy makers should center their focus on reforms that will ensure that more people are financially included in the region. Also policies promoting high growth levels and acquisition of higher levels of education should be pursued. , Thesis (MCom) (Economics) -- University of Fort Hare, 2021

- Description: Ntabankulu extends from latitude 30° 51' 09"S to 31° 09' 10" S and from longitude 29° 06' 51"E to 29° 23' 49"E in the Eastern Cape Province of South Africa. Ntabankulu Local Municipality has 141 villages with 125 976 population size. About 36% of villages do not have water sources, 38% have partial functional water sources, 6% have non-functional water sources, and 20 % have reliable water sources, primarily rivers (Mnceba, Caba and Mzimvubu). Water is scarce in this area, especially in the dry season when perennial rivers and springs become dry. This research investigates groundwater potential zones and identifies suitable aquifers that can be developed to augment the water resources. The study involved: literature review, remote sensing, borehole and springs data, geological, petrographic and geophysical (gravity, magnetic and electrical resistivity) analyses. Each method has its purpose in finding the potential groundwater zones. Ntabankulu Local Municipality is located on the Karoo Supergroup in Ecca and Beaufort Group, Adelaide Subgroup and Balfour Formation. During field analysis, it was observed that this area consists of sandstone, shale and dolerite sills, dykes and complex rings. Fining up sequences, massive bedding, concretions, and spheroidal weathering were observed in sandstone, shale, and dolerite, respectively. Groundwater seepages are found within these structures. Sandstones are yellow due to the presence of limonite because of the continuous seepage. Red coloured laminated shale reflects that the rock has an iron oxidation state with hematite (Fe2O3) on the sediments. The Geographical Information Systems (GIS) method was used to extract lineaments. Lineaments dominate Ntabankulu with an NW-SE direction. Some of the lineaments are due to Karoo igneous intrusions, and others are due to neotectonic activities. Ntabankulu is located on the eastern and northern neotectonic belts. Geological maps and lineament maps were compared; it was observed that sandstones and shales are found on high liinament density areas. High yielding boreholes and springs coincide with lineaments, and some lineaments are faults. Hence areas that have high lineaments density could be groundwater potential zones. There are geological structures (faults, joints, and fractures) that are present. Systematic and non-systematic joints are found on sandstones which are due to extensional stress. These joints have been reactivated and acted as strike-slip faults. All these geological structures increase the porosity and permeability of the rocks. It was observed that the area of Ntabankulu consists of coarse-grained and medium-grained sandstone with quartz and orthoclase minerals. Dolerite consists of labradorite, clinopyroxene, olivine, oxide minerals with twinning formed during cooling and magma crystallisation. The gravity and magnetic methods were used to study the subsurface rock density contrasts and susceptibilities, respectively. The gravity and magnetic maps were generated in Geosoft Oasis 8.3 software. High gravity zones coincide with some of the mapped Karoo intrusions. Unmapped dolerite intrusions, lineaments and faults were inferred. The magnetic method delineated the subsurface structures (lineaments and faults), which are known to control groundwater accumulation. These structures and inferred dolerite intrusions helped in identifying groundwater potential zones. Groundwater potential zones were inferred in sedimentary rocks between dolerite intrusions and areas where sills and dykes intersect. A total of six vertical electrical soundings (VES) were conducted at Mzalwaneni and Tabankulu town areas using the Schlumberger configuration array with a maximum penetration depth of about 25- 33 m. The VES data were modelled in Winresist and Surfer 9 software to obtain 1D models and geoelectric sections, respectively. These 1D models have three layers with response curves of H-type. The top layer is about 0.4 - 0.7 m thick, with resistivity values from 12.3 – 1885.9 Ωm and is topsoil (sand and clay). The second layer of thickness 5.2 – 13.3 m has low resistivity values from 23.1- 44.9 Ωm. This layer is interpreted to be fractured shales and sandstones possibly containing water. The third layer of high resistivity values of 145.9 – 727.4 Ωm is inferred to be sandstone. The simultaneous interpretation of resistivity and normalised chargeability revealed that groundwater potential zones are characterised by low resistivity values and low normalised chargeability values for layers from 0.7 - 13.3 m depth. The groundwatwer in the area of Ntabankulu can be found on unconfined aquifers. , Thesis (MSc) -- Faculty of Science and Agriculture, 2021

- Description: Coastal urban expansion is on an upward trajectory, which poses serious threats to ecosystem functioning, human wellbeing and the general environment across the globe. It is on this premise that this study brings to the fore the growing complexity of environmental sustainability problems in a former apartheid space, as characterized by coastal urbanization and the intricacies of vegetation conservation. Consequently, literature utilized for this study reveals that urban expansion has led to an uncontrolled threat to the coastal ecosystem, culminating in soil erosion, environmental pollution through illegal dumping of solid waste, loss of coastal vegetation to other land use types, among others. Therefore, constant monitoring of these spaces is needed due to their fragility, as they are pivotal in the earth-atmosphere processes to the benefit of the entire humanity. To this end, the current study offers critical analysis and insights about the South African coastal ecological space. The essence of using BCMM in its consideration as an ecological space and former apartheid territory brings to the fore a scientific explanation of the spatial configuration and changes in the CVEs of the study area during the post-colonial era. In the course of investigating this study, the Urban Green Sustainability (UGS) theory was adopted in the course of selecting the review of literature, methodological approach and analysis of results. A mixed methodological approach (qualitative, quantitative and geospatial techniques) was explored in data collection and analysis. 254 copies of the questionnaire were returned and analysed for this research. Results generated revealed by the BCMM respondents confirms the occurrence of uncontrolled urbanization, deforestation and crop cultivation as major causes of coastal vegetation loss. In the same vein, the LULC classification results revealed that about 466 km2 of forest vegetation has been lost in BCMM from 1998-2018. Also, LULC classification results were validated by performing the Normalized Difference Built-Up Index (NDBI), Normalized Difference Vegetative Index (NDVI), Kappa’s coefficient (k), coefficient of determination (R2) and Pearson’s Product Moment Correlation (P) tests. The results also revealed that the built-up area had increased from 194 km2 in 1998 to 814 km2 in 2008. Further, all statistical tests revealed very good and highly correlated overall classification accuracies (of R2=0.89 and P=0.86) during the study period (1998 – 2018). This study makes a clarion call towards the rehabilitation of degraded coastal environments and proffers solutions towards the actualization of environmentally sustainable CVEs which offers optimal ecosystem services. , Thesis (PhD) -- Faculty of Science and Agriculture, 2021

- Description: Much has been written on the scourge of human trafficking, with majority of previous research focussing on trends, forms, as well as the regulatory framework for countering the scourge. Despite the presence of a vast body of knowledge on human trafficking, less attention has been given to the operational dynamics that are involved in the investigation and prosecution of human trafficking cases. This paper, which is based on a literature and documentary survey, evaluates the challenges that are encountered by the criminal justice players in responding to human trafficking. The paper specifically focuses on the challenges that are faced by law enforcement agencies in the investigation of human trafficking, as well as the challenges that are faced in the prosecution of human trafficking offenders. Whilst the paper takes a global approach to the problem, much attention is given to South Africa and Zimbabwe- two neighbouring Southern African nations.

- Description: Studies have revealed that persistent organic pollutants (POPs) are omnipresent in our environment; almost all human beings have definite levels of POPs in their bodies. Even fetus and embryos are not spared; they have been found to bear certain levels of POPs. So far, there are about 28 chemicals listed as POPs among which are polybrominated diphenyl ethers (PBDEs) and polychlorinated naphthalenes (PCNs). PCN and PBDE distributions have been reported from different sources around the world, but studies relating to PCNs occurrence and distribution in Africa, especially South Africa is still minimal. PBDEs have been reported to cause diabetes, cancer, damage to reproductive system, thyroid, liver and other vital organs in the body, while PCNs have been linked to chloracne (severe skin reactions/lesions) and liver disease (yellow atrophy) in humans, chicken oedema and X-disease in cattle. Hence, this study evaluates PCN levels in water and sediment samples from three waterbodies: North End Lake (NEL), Chatty River (CHA) and Makman Canal (MMC), while PBDE levels was reported in NEL and CHA samples. The three sites are located in Port Elizabeth, Eastern Cape Province (ECP) of South Africa. The lake serves as a recreational resort while the latter two waterbodies are tributaries discharging into the Swartkop Estuary, an important estuary in ECP. Water samples were extracted with C18 cartridges (solid phase), while soxhlet was employed for the extraction of sediments. Water and sediment extricates were purified and quantified with gas chromatography-micro electron capture detector (GC-μECD). Forty-seven (47) water samples and 44 sediment samples were collected in August until December 2020 from six sampling points in NEL, five points in each of CHA and MMC. All the samples were evaluated for physicochemical properties, PBDEs and PCNs using validated standard methods. The sampling period covered three South Africa seasons: August (winter), October (spring) and December (summer). The physicochemical parameters (PP) of NEL water samples for the three seasons generally varied as follows: temperature (15.3–23°C), pH (7.9–10.3), oxidation-reduction potential, ORP (23.4-110 mV), atmospheric pressure, AP (14.52-15.56 PSI), turbidity (15.1–167 NTU), electrical conductivity, EC (114–1291 μS/cm), total dissolved solids, TDS (55-645 mg/L), total suspended solids, TSS (20–107 mg/L) and salinity (0.05–0.65 PSU). All the PPs except for turbidity and TSS are within acceptable limits. NEL sediments had moisture content (MC), organic matter (OM) and organic carbon (OC) in the range of 0.04–8.0percent, 0.08–2.2percent and 0.05–1.8percent, respectively. The sum of eight PCN congeners Σ8PCNs and six PBDE congeners Σ6PBDEs in NEL water samples ranged from 0.164–2.934 μg/L and 0.009-1.025 μg/L individually. The values for Σ8PCNs and Σ6PBDEs in NEL sediment samples varied from 0.991–237 μg/kg and 0.354-28.850 μg/kg, respectively. The calculated hazard quotient (HQ) corresponding to the non-carcinogenic health risk associated with PBDEs in NEL water samples was 2.0×10-3-1.4×10-1, while the TEQ values due to PCNs varied from 6.10×10-7- 3.12×10-3 μg/L in NEL water samples and 3.70×10-5-1.96×10-2 μg/kg dw in sediments. The PP values for CHA water samples include temperature (15.4–22.9°C), pH (7.7–10.5), TDS (991–1771 mg/L), TSS (6–41 mg/L), turbidity (1.0–198 NTU), EC (1981–3542 μS/cm), AP (14.60–14.80 PSI), ORP (-339.1-51.3 mV), and salinity (1.02–1.87 PSU). The EC, TDS and salinity exceeded acceptable values at certain points. The sediments of CHA have MC, OM and OC contents ranging from 0.01-10.2percent, 0.2-1.3percent and 0.1-0.8percent in that order. Sum of Σ8PCNs, Σ6PBDEs in CHA water and sediment samples ranged from 0.026–1.054 μg/L, 0.007-0.079 μg/L and 0.429–1888.468 μg/kg, 0.347-6.468 μg/kg individually. The HQ in CHA water samples was 1.6×10-3-7.7×10-3 and the estimated TEQ was 1.0×10-7-6.62×10-5 μg/L and 1.10×10−5-6.40×10−2 μg/kg in water and sediments, respectively. The temperatures for MMC water samples ranged from 15.6-24.5°C, while other PPs recorded were as follows: pH (8.4-10.2), TDS (943–4002 mg/L), TSS (7-491 mg/L), turbidity (2.9-154.2 NTU), EC (1885-8004 μS/cm), AP (14.53–14.82 PSI), ORP (7.8-130 mV) and salinity (0.96-4.47 PSU). MMC’s sediments recorded MC, OM and OC varying as 0.4- 18.9percent, 0.2-4.5percent and 0.1-2.6percent, respectively across the three seasons. The Σ8PCNs for MMC water and sediment samples were 0.035–0.699 μg/L and 0.260–6744 μg/kg. The TEQ values in MMC water and sediment samples were 1.19×10-7-1.47×10-4 μg/L and 4.43×10−5- 4.19×10−1 μg/kg, respectively. The results are all less than one, and this suggests that the selected water is safe. Results showed that NEL water had highest TEQ, PCN and PBDE concentrations, while MMC sediments recorded maximum TEQ and PCN levels in this study. PBDE concentrations in NEL sediments were above the other site. In conclusion, NEL water was most polluted with both pollutants (PCNs and PBDEs), but MMC sediments contained more PCNs. There is need for the immediate remediation of these selected waterbodies. , Thesis (PhD) -- Faculty of Science and Agriculture, 2021

Water and sediment extricates were purified and quantified with gas chromatography-micro electron capture detector (GC-μECD). Forty-seven (47) water samples and 44 sediment samples were collected in August until December 2020 from six sampling points in NEL, five points in each of CHA and MMC. All the samples were evaluated for physicochemical properties, PBDEs and PCNs using validated standard methods. The sampling period covered three South Africa seasons: August (winter), October (spring) and December (summer). The physicochemical parameters (PP) of NEL water samples for the three seasons generally varied as follows: temperature (15.3–23°C), pH (7.9–10.3), oxidation-reduction potential, ORP (23.4-110 mV), atmospheric pressure, AP (14.52-15.56 PSI), turbidity (15.1–167 NTU), electrical conductivity, EC (114–1291 μS/cm), total dissolved solids, TDS (55-645 mg/L), total suspended solids, TSS (20–107 mg/L) and salinity (0.05–0.65 PSU). All the PPs except for turbidity and TSS are within acceptable limits. NEL sediments had moisture content (MC), organic matter (OM) and organic carbon (OC) in the range of 0.04–8.0percent, 0.08–2.2percent and 0.05–1.8percent, respectively. The sum of eight PCN congeners Σ8PCNs and six PBDE congeners Σ6PBDEs in NEL water samples ranged from 0.164–2.934 μg/L and 0.009-1.025 μg/L individually. The values for Σ8PCNs and Σ6PBDEs in NEL sediment samples varied from 0.991–237 μg/kg and 0.354-28.850 μg/kg, respectively. The calculated hazard quotient (HQ) corresponding to the non-carcinogenic health risk associated with PBDEs in NEL water samples was 2.0×10-3-1.4×10-1, while the TEQ values due to PCNs varied from 6.10×10-7- 3.12×10-3 μg/L in NEL water samples and 3.70×10-5-1.96×10-2 μg/kg dw in sediments. The PP values for CHA water samples include temperature (15.4–22.9°C), pH (7.7–10.5), TDS (991–1771 mg/L), TSS (6–41 mg/L), turbidity (1.0–198 NTU), EC (1981–3542 μS/cm), AP (14.60–14.80 PSI), ORP (-339.1-51.3 mV), and salinity (1.02–1.87 PSU). The EC, TDS and salinity exceeded acceptable values at certain points. The sediments of CHA have MC, OM and OC contents ranging from 0.01-10.2percent, 0.2-1.3percent and 0.1-0.8percent in that order. Sum of Σ8PCNs, Σ6PBDEs in CHA water and sediment samples ranged from 0.026–1.054 μg/L, 0.007-0.079 μg/L and 0.429–1888.468 μg/kg, 0.347-6.468 μg/kg individually. The HQ in CHA water samples was 1.6×10-3-7.7×10-3 and the estimated TEQ was 1.0×10-7-6.62×10-5 μg/L and 1.10×10−5-6.40×10−2 μg/kg in water and sediments, respectively. The temperatures for MMC water samples ranged from 15.6-24.5°C, while other PPs recorded were as follows: pH (8.4-10.2), TDS (943–4002 mg/L), TSS (7-491 mg/L), turbidity (2.9-154.2 NTU), EC (1885-8004 μS/cm), AP (14.53–14.82 PSI), ORP (7.8-130 mV) and salinity (0.96-4.47 PSU). MMC’s sediments recorded MC, OM and OC varying as 0.4- 18.9percent, 0.2-4.5percent and 0.1-2.6percent, respectively across the three seasons. The Σ8PCNs for MMC water and sediment samples were 0.035–0.699 μg/L and 0.260–6744 μg/kg. The TEQ values in MMC water and sediment samples were 1.19×10-7-1.47×10-4 μg/L and 4.43×10−5- 4.19×10−1 μg/kg, respectively. The results are all less than one, and this suggests that the selected water is safe. Results showed that NEL water had highest TEQ, PCN and PBDE concentrations, while MMC sediments recorded maximum TEQ and PCN levels in this study. PBDE concentrations in NEL sediments were above the other site. In conclusion, NEL water was most polluted with both pollutants (PCNs and PBDEs), but MMC sediments contained more PCNs. There is need for the immediate remediation of these selected waterbodies. , Thesis (PhD) -- Faculty of Science and Agriculture, 2021

- Description: Gender-based violence is a global epidemic. Masculinities-focused interventions have a positive influence on behaviour and contribute toward positive attitudes and gender equality (Das et al., 2012). These interventions have a positive influence on factors associated with gender-based violence. However, some studies found that this influence is behavioural and does not influence patriarchal beliefs (Jewkes et al., 2010; Roy & Das, 2014). Highlighting that intervention on gender-based violence requires redress. This research sought to establish what has been published in academic literature on the influence of masculinities on gender-based violence. The research was addressed through the social constructionist paradigm; it used a mixed methods approach to research. A content-analysis was applied to 100 published academic articles that were sampled from the University of Fort Hare’s online library database using purposive sampling. The research method and design is appropriately suited to the theoretical framework – social constructionism. Qualitative Data Analysis (QDA) software was used to code the quantitative and qualitative data through deductive and inductive means. The quantitative results were interpreted using descriptive statistics. The qualitative findings were analysed using thematic analysis (Braun and Clarke, 2006). The research in this sample is mostly qualitative, majority of the research within the sample was published between 2007 and 2018, and male participants are primarily focused on within research on this topic. Majority of the research within the sample was conducted using North American Participants. The findings support previous literature. They indicated that masculine norms, compensatory masculinity, and victimization of gender non-conforming individuals are the most prominent themes within the sample. The results indicated various gaps within the research. There is an indication that different dimensions of masculinity are associated with different forms of gender-based violence. It is recommended that future research focus on the different dimensions of masculinity and their association with various forms of genderbased violence in order to appropriately inform preventative strategies and intervention. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2021

- Description: This study analyses a selected cohort of black South African novelists‟ depiction of the real burning issues of the post-Apartheid South Africa. The ideas that the study is concerned with in the novel under study, are based on the aspect of theme and how it is utilised by the respective authors to address the social, economic and political issues in the post-Apartheid South Africa. The study is an investigation of the extent to which black South African novelists have depicted the aforementioned issues. The research highlights those issues that the novels under study addressed and continues by revealing how the authors depict these issues in their texts. Moreover, the study concludes that literature has a role to play in the society and recommends that it should be reliable and useful to the society. It further recommends that literature should not ignore societal issues and should be corrective in its approach. The study is comprised of six chapters: Chapter One functions as an introduction to the study. It provides information on the aims and objectives of the study, the background information on the novels under study and South African literature itself. The chapter also outlines the method and the theories, which will be used in the study. It concludes by addressing the significance of the study. Chapter Two provides a detailed analysis of the theories, which will be used in the study. This includes the Marxism and Realism theory, Afrocentric theory and the Feminist Literary theory. It also defines the concept of theme and outlines its characteristics. It discusses post-colonial literature and its development in Africa. The chapter will conclude with a disclosure of the role of theme and of the author in the African novel. Chapter Three addresses the depiction of burning issues in Mpe‟s novel “Welcome to Our Hillbrow”. It discusses the real post-colonial challenges confronting the society during the post-Apartheid South Africa. It determines whether the novel under study adequately addresses these issues. Chapter Four identifies and addresses the depiction of burning post-colonial issues in Magona‟s novel “Beauty‟s Gift”. It unveils the themes that are dealt with in the novel under study thereby linking them effectively to the current situation in the new South Africa. Chapter Five unveils the central themes in Mahala‟s Novel “When a Man Cries” and it illustrates how the author protests against the ills of post-Apartheid South Africa. Chapter Six serves as the conclusion of the study and brings out the findings and recommendations of the study. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2021

- Description: Soap operas are no longer only televised but the producers or content creators are branching out to other media, to make their content available to all kinds of audience. Increasingly, soap opera episodes can be shared not only on TV but also on the internet and this means its audience reach is extended. The focus of the study was on online audience of the South African soap opera 7de Laan, this exploratory study was conducted to assess the participation and activities of an online fan community. The study focused on a convenience sample of 10 asynchronous commentary forums attached to the 7de Laan YouTube channel. The sample included 1011 participants collectively providing 2312 comments. User names are not used in this study. The study intended to achieve the following objectives: 1. To conduct a qualitative content analysis of references to characters during the course of the ten episodes; 2. To find out what the users say about those characters and the plots in which they occur; and 3. To measure the coding in order to gain an impression of the interests and concerns of participants making up the online audience with respect to the soap opera narrative. The data set was coded and explored by means of the Qualitative data analysis programme NVivo 10. The raw material was collated into individual files for each participant, and imported into analysis programme. The analysis proceeded as three stages. The first stage revealed those characters that interested participants, ranging from those who attracted the most interest, to those who attracted the least. The second stage aimed to find out what themes coincided with these characters. The third stage aimed to find out what participants through about the soap opera 7de Laan itself. These stages correspond to three sets of appendices. The findings show a close correspondence between the relative airing of the five sub-plots that constitute the soap opera narrative, and the interest that online audience participants show through their comments. , Thesis (MSoc Sci) (Communication) --Faculty of Social Science and Humanities , 2021

- Description: In the past two decades, there has been increasing pressure for small-scale inland fisheries to play a central role in food and nutrient security for poor communities in South Africa. For decades, South African inland fisheries have focussed on the exploitation of large fish species and generally ignored the exploitation of inland small fish species (SFS). This research aimed to assess the ecology and small-scale fishery potential of the estuarine round-herring, Gilchristella aestuaria. To understand the ecology of G. aestuaria better, morphometric trait analysis and fish condition of populations in relation to environmental variables (salinity, pH, temperature, turbidity and chlorophyll-a) were done. Fish were supplemented with samples acquired from the SAIAB collection facility for 14 sites to cover all the three South African biogeographic regions, stretching from Lake Sibaya (KZN) to the Orange River estuary in the western parts of the country. The morphometric trait analysis showed that G. aestuaria populations can be distinguished based on the trait variation, however there were many overlaps for populations that are interconnected, with distant/ geographically separated populations showing clear differences. Morphometric traits of the G. aestuaria population were significantly different, however there was no strong directional relationship with environmental variables and variation in morphometric traits. However, fish condition as measured by Fulton’s condition (K) and relative weight (Wr) showed variation between populations found in different environments. These differences suggest that these populations must be managed differently if G. aestuaria is to be exploited in managed fisheries. To determine the potential nutrient value of G. aestuaria to the human diet, samples from two freshwater sites and five estuarine sites were analysed for essential macro and micronutrients. The nutrient content of G. aestuaria revealed there is potential for exploitation, as the species has a high macro (protein and fat) and micronutrient composition (calcium, iron and zinc). Mean ± SD of selected nutrients were protein (61.7±5.0 g/100g), fat (20.4±3.7g/ 100g), calcium (3507.5±314.0mg), iron (40.37±14.0mg/ 100g), zinc (22.47±5.6mg/ 100) and vitamin A (37.3±44.4 RAE/ 100g). The nutrient composition of fish collected from freshwater sites was comparable to those collected from estuarine environments. Using the recommended dietary allowances (RDA) from literature, the mass of fish and the number of fish that would provide a minimum amount for each nutrient were calculated. A child would require only 13.4g of dry G. aestuaria or approximately 74 dried fish to meet the daily requirements of zinc. Other minerals such as iron and calcium also showed a similar low weight or number of fish required to meet daily requirements for the different categories. A small number of G. aestuaria are needed to meet RDA for groups (children, adult men, adult women, pregnant women and lactating mothers). A comparison was done for the nutrient composition of G. aestuaria with reference species that are already harvested for human consumption in some African and Asian countries. The protein content of G. aestuaria was comparable to Chisense (Microthrissa moeruensis) and Kapenta Limnothrissa miodon), while the fat composition was more than twice Chisense and Kapenta. Comparing the mineral composition, G. aestuaria had more than three times higher calcium than Mola (Amblypharyngodon mola) and Puti (Puntius sophore). Zinc composition was four times higher than M. moeruensis and L. miodon. Further exploration of the ecology of G. aestuaria was studied using the Sundays River irrigations ponds as a case study that would represent small impoundments across South Africa. Species rank abundance curve and catch per unit effort (CPUE) on the Sundays Irrigation ponds revealed that G. aestuaria dominated numerically and biomass in the Sundays River irrigation ponds. To assess the potential of harvesting G. aestuaria harvesting experiments were conducted using depletion (removal) sampling. Catchweight (kg) ranged from 2.16 (1.03; 3.28) to 61.25 (44.40; 78.09) kg and the estimated biomass from the depletion model ranged from 1.05 to 40.19 kg/ha for September 2019. The depletion model revealed that small impoundments have high biomass per hectare of G. aestuaria ranging from which indicates that the species may not support a commercial fishery but small-scale fisheries. In conclusion, G. aestuaria could become a meaningful contribution to the food and nutrient security of poor communities where available as a food source through small-scale fishery exploitation. The extent of this contribution may depend on its production potential in various regions and environments. More research is however needed to determine the long-term sustainability of harvesting of G aestuaria by looking at how populations respond to harvesting. , Thesis (PhD) -- Faculty of Science and Agriculture, 2021

- Description: The increasing incidences of climate change and its registered negative effects have disturbed the entire world, with the coastal areas being the worst hit. Given the fact that coastal areas are becoming centres of global population settlement. An attempt to explore climate change-related disasters and risks is an important aspect in building communities' adaptation and resilience, especially for the most vulnerable global south. Consequently, climate change adaptation (CCA) and disaster risk reduction (DRR) have become fundamentally linked to offering sustainable solutions to address climate change and related disaster risk problems witnessed frequently in recent years. However, the assessment of synergy between CCA and DRR for coastal areas remains fragmented, vague and limited, especially for Sub-Saharan Africa and thus the need for exploration. Furthermore, the urban populace and planning stakeholders are grappling with the challenges of seeking ways to integrate adaptation measures into human livelihoods and planning systems. Also, considering complex issues inhibiting sustainable planning, for example, poor communication of climate risks affecting coastal areas, little records of hazards disclosure and disaster history, inundation and/or sea level rise etc warranted further investigation. Accordingly, the synergies between CCA and DRR in addressing various climate change-related disaster risks, especially for the coastal areas and cities was explored in this study. To this end, given the complexity of CCA and DRR, trio-theories were adopted, which included Resilience Theory (RT), Social Vulnerability Theory (SVT) and Protective Motivation Theory (PMT) as the study’s theoretical underpinnings using East London Coastal City as a case study. Consequently, a multi-method approach was employed using a review of literature, bibliometric analysis, field survey, geographic information system (GIS), and remote sensing. The first objective reveals that there is a need for convergence and harmonisation of CCA and DRR policy, programme, and practice to improve sustainable planning outcomes. Accordingly, the study proposed the adoption of a problem analysis model (PAM) for place function sustainability and local or community level resilience building. The second objective revealed that the Sendai framework for disaster risk reduction has not been fully operationalised at the local and global scales. However, in South Africa, there are efforts to streamline DRR across manifold sectors through the Integrated Urban Development Framework (IUDF). Therefore, disaster risk managers and climate change adaptation stakeholders at the local level need to embrace the position of the SFDRR to possibly offer sound and sustainable results to the most vulnerable. In addition, a bibliometric analysis on climate change adaptation from 1996 – 2019 highlights the need for more African countries' engagement and cross-collaboration between developing and developed countries in CCA research to advance sustainable solutions and improve resilience. The third objective revealed the need for more awareness, flexibility, and adaptability among stakeholders at various levels as fundamental ingredients for CCA and DRR sustainable planning outcomes. The fourth objective highlighted that floods were recorded as the most predominant hydro-meteorological hazard (n=118, 81.9percent) in the East London, coastal city. Finally, the fifth objective portrayed that many communities, populace, buildings (types), and areas are exposed to flood disaster risks, especially, communities such as Nahoon Park Valley, Sunrise on Sea, Beacon Bay, Buffalo, Gonubie, and East London are among the most vulnerable. The study recommends that early action and warning systems should be adopted, and allocation proper building codes to boost awareness to reduce the potential flood disaster risks. Moreover, the study reveals the significance of local flood disaster risk mapping in advancing CCA and DRR to ensure the implementation of coherent spatial planning for sustainable planning outcomes. The overall lessons learnt from this study are vital in contributing to the attainment of the sustainable development goals (SDGs) such as goal 11: sustainable cities and communities, and goal 13: climate action, including the seven targets and four priorities for action of the Sendai framework at a local level. The study results are deemed critical in guiding city planners, decision-makers, disaster risk managers, local communities among others towards the development of a more resilient coastal community. In general, the study calls for the integration of CCA and DRR initiatives to be premised on PAM for sustainable planning outcomes to achieve sustainable development goals and reduction of fatalities from climate-related disasters. , Thesis (PhD) -- Faculty of Science and Agriculture, 2021

- Description: The increasing incidences of climate change and its registered negative effects have disturbed the entire world, with the coastal areas being the worst hit. Given the fact that coastal areas are becoming centres of global population settlement. An attempt to explore climate change-related disasters and risks is an important aspect in building communities' adaptation and resilience, especially for the most vulnerable global south. Consequently, climate change adaptation (CCA) and disaster risk reduction (DRR) have become fundamentally linked to offering sustainable solutions to address climate change and related disaster risk problems witnessed frequently in recent years. However, the assessment of synergy between CCA and DRR for coastal areas remains fragmented, vague and limited, especially for Sub-Saharan Africa and thus the need for exploration. Furthermore, the urban populace and planning stakeholders are grappling with the challenges of seeking ways to integrate adaptation measures into human livelihoods and planning systems. Also, considering complex issues inhibiting sustainable planning, for example, poor communication of climate risks affecting coastal areas, little records of hazards disclosure and disaster history, inundation and/or sea level rise etc warranted further investigation.

- Description: This study was conducted to explore and understand how black South African parents residing in a township, experience raising a child with an intellectual disability. It was important to investigate this under-researched phenomenon to have a holistic understanding of the personal experiences and meanings that black South African parents have over the years attached to, and experienced in their journeys of raising a child with intellectual impairments in low economic areas. An Interpretive qualitative approach was adopted to explore and understand the experiences of raising a child with an intellectual disability in a township by black South African parents. Non-probability snowball and purposive sampling methods were used to develop the sample for this study. Four parents residing in two townships (Mdantsane and Ducan Village) around the Buffalo City Municipality which is situated in the Eastern Cape province participated in this study. Data was collected through personal, face to face and individual interviews which were audio-recorded and transcribed verbatim. Braun and Clarke’s six steps of thematic analysis was employed to analyse the data that was collected. The results of this study showed that raising children with intellectual disabilities in a township is challenging. Parents tend to feel that they are alone on this journey because of the lack of support, acceptance and understanding they receive from family members, the community and even teachers. Furthermore, the study found that being financially disadvantaged is a challenge when it comes to raising a child with an intellectual disability. Participants in this study indicated that the unconditional love they have for their children motivates them daily to raise their children and that they have hopes and dreams for their children despite the children’s impairments. This study recommends that the department of education hold more psychoeducation workshops on intellectual disability, especially for teachers in mainstream and inclusive schools who educate children with intellectual disabilities. Furthermore, more awareness campaigns in townships to educate the community on intellectual disability are recommended. , Thesis (MSoc Sci) (Counselling Psychology) --Faculty of Social Science and Humanities, 2021

- Description: My thesis is a collection of prose pieces in the form of short stories, flash fiction and prose poetry drawing on memory and lived experiences to explore the trauma of death, grief and displacement, solace and the paroxysms of home. As a young woman from an Indian South Africa community, Hindu superstitions and folktales are my second skin, and shape both my worldview and my writing. I am inspired by Lidia Yuknavitch’s observation that, “all artists see things that are not there”, and by Dambudzo Marechera’s belief that, “Beneath reality, there is always fantasy: the writer’s task is to reveal it, to open it out, to feel it, to experience it.” In my stories about trauma and grief, I often distort the line between seen and unseen worlds, where, for example, hauntings are taken seriously as lived experiences. I have also been influenced by Han Kang’s The White Book, Kali Fajardo-Anstine’s Sabrina & Corina, and Sandra Cisneros’ The House on Mango Street. Read together, Kang’s stand-alone short stories form part of a greater collective ‘memory’ or ‘life’; Fajardo-Anstine’s collection illustrates how to write about a specific female Latina community while still telling individual stories; and Cisneros’ fragments of memories tell the story of a person’s life in narratives which are as long or short as they need to be. , Thesis (MA) -- Faculty of Humanities, School of Languages and Literatures, 2021

- Description: Jeffrey Lionel Dahmer is an infamous serial killer and cannibal. He was described as a normal, but shy little boy, yet developed into an adult who brutally murdered, engaged in necrophiliac acts, dismembered and ate parts of his victims. This study took the form of an intrinsic case study with the aim to explore and describe the personality development of Jeffrey Dahmer. This exploration examined Dahmer’s known childhood experiences through the theoretical perspective of Otto Kernberg’s (1974, 1975, 1976) Object Relations Theory, in order to understand how Dahmer’s personality was formed. Data was collected from multiple resources, including books, authoritative biographies, academic articles, and internet sources available in the public domain. It was analysed using Miles, Huberman, and Saldaña’s (2014) three-step process namely, data condensation, data display, and conclusion drawing and verification. This study’s findings confirmed the formation of pathological behavioural patterns supported by primitive defence mechanisms, associated with Kernberg’s lower level pathologies. It reflected Dahmer’s pathological formation of psychic structures seen in a diffuse identity and impaired formation of the superego, that supported these patterns. Additionally, the research was valuable in enhancing the researcher’s insight into personality development according to Kernberg’s Object Relations Theory. This study may also be beneficial to practising clinicians and professionals as an example of the early identification of personality pathology. , Thesis (MA) -- Faculty of Health Sciences, 2021

- Description: The Government of Zimbabwe is operating using the mantra: ‘Zimbabwe is open for business’. The notion of opening for business requires robust supporting economic infrastructure for enhanced productivity, in the form of reliable supply of electricity, accessible road/railway transport networks and availability of contemporary Information Communication Technology (ICT) infrastructure. The aim of the study was to develop a framework for making financing decisions for public infrastructure in Zimbabwe. The objectives of the study are to: determine the main sources of public infrastructure financing in Zimbabwe; establish innovative finance’s capacity to close the public infrastructure financing gap in Zimbabwe; assess the role played by public-sector accounting in attracting appropriate and efficient mechanisms to finance public infrastructure in Zimbabwe; and ultimately to develop and recommend a framework for selecting suitable and efficient mechanisms to finance public infrastructure in Zimbabwe. According to literature reviewed, public infrastructure is broadly financed by public sector entities using their own resources (internally financed) or through private sector investments and innovative financing instruments (externally financed). When infrastructure is internally financed, the study is theoretically guided by the Public Goods Theory and the Theory of Public Finance and Public Policy. When externally financed, the Risk Return and Pecking Order theories are important. There are many instruments used to finance public infrastructure and one project may be financed using one or more instruments. Therefore, considerations are given to the need for a framework that helps improve the efficiency of the financing decision. The study was designed as a multiple case study that focused on four sectors of economic infrastructure, that is, transport, energy (electricity), ICT as well as water and sanitation. The research used synchronous mixed methods to achieve the objectives of the study. Qualitative research methods addressed the following objectives: a) to determine the main sources of public infrastructure financing in Zimbabwe; b) to establish innovative finance’s capacity to close the public infrastructure financing gap in Zimbabwe; and c) to assess the role played by public-sector accounting in attracting appropriate and efficient mechanisms to finance public infrastructure in Zimbabwe. Whilst to develop and recommend a framework for selecting suitable and efficient mechanisms to finance public infrastructure in Zimbabwe the study combined qualitative and quantitative research methods. Qualitative data was collected through interviews conducted with officials and staff from government ministries, government departments, as well as parastatal enterprises dealing with the four infrastructure types. The same respondents were asked to complete a survey questionnaire used to address part of the objective that developed a framework for public infrastructure financing. Interview data were triangulated using secondary data extracted from reports and financial statements. Some of the secondary data was collected from the World Bank’s development indicators online repository. Qualitative data analysis was done using RQDA, an open-source computer-aided data analysis software. Findings from the study revealed that the main sources of finance for public infrastructure in Zimbabwe are the government through budget appropriations, and concessionary loans from the China Export-Import Bank. There was also finance obtained from multilateral financial institutions such as the Development Bank of Southern Africa and the African Export-Import Bank. The study revealed that there is currently very limited use of innovative financing instruments such as PPPs in financing public infrastructure in Zimbabwe, despite the country having legislation to support such financing arrangements. The innovations in financing observed in the study entail the use of conventional financing mechanisms in unconventional ways. However, there is scope for improving the financing of public infrastructure using innovative financing mechanisms and significantly mitigate the financing gap. Public sector accountants in Zimbabwe are mainly active in financial reporting, although the financial statements for most ministries, government departments and parastatal enterprises had qualified audit opinions from the Auditor General’s office. Public sector accountants are not active in financial management and cost and management accounting responsibilities. As a result, public sector accountants are not adding value to public money through offering advisory services in the efficient investment of public money, as well as financing public infrastructure assets using the most efficient financing mechanism. There is no uniformly applied framework when making financing decisions for public infrastructure in Zimbabwe. Therefore, a framework was developed and is recommended for use by this study. The developed framework entails eight steps that are interrelated and interconnected. Use of the proposed framework requires availability of data about infrastructure projects that have been done in the past. The study recommends that Zimbabwe should ensure a robust framework for protecting private sector investments, which can be achieved by ensuring policy consistency; creating and implementing a legal framework that protects private capital; and having economically viable infrastructure sectors, that are liberalised to allow private sector participation. The Government of Zimbabwe must take deliberate actions that ensure variety of financing options at the disposal of the public sector to lower costs of financing public infrastructure. It is also important to fully operationalise the legislation and policies designed to facilitate the participation of the private sector in financing public sector projects. Such operationalisation entails a decentralisation of the regulations and policies to the provincial and municipal levels. , Thesis (PhD) -- Faculty of Business and Economic Sciences, Accounting, 2021

- Description: In South Africa, substance abuse and sexual assault and/or abuse are major concerns. Society has become desensitised to these topics because of its high prevalence rate. Substance abuse is often greeted with stereotypes and prejudices that view individuals as a problem to society. The proposed research employed a qualitative, exploratory, and descriptive strategy of inquiry, guided by narrative biographical research design. Social constructionism was employed as a theoretical framework to explore how an individual had constructed her life story, with a specific focus on her experience of sexual trauma and subsequent substance abuse. A non-probability purposive sampling method was used to recruit a research participant who was in the public domain as a motivational speaker in an attempt to guard against retraumatisation. Two data collection methods were employed, namely one-on-one semi-structured interviews and an invitation to the participant to journal about her experience, guided by specific stimulus questions. Thematic narrative analysis was employed as a method of data analysis. The outcome of the investigation had provided a narrative account of the research question at hand with the following themes coming to the forefront:- Early childhood experiences ( pre-sexual abuse), sexual trauma, recovery and meaning making. , Thesis (MA) -- Faculty of Health Sciences, 2021

Such a genealogical exploration thematises the games of truth underpinning the formation of Huisgenoot, highlights its role in solidifying white Afrikaner Nationalist discourse of apartheid, observes its more populist, profit-oriented approach from the 1970s onwards and considers the residual echoing of its former discursive orientation. The song analysis of selected Afrikaans songs/music videos covered in Huisgenoot is guided by the semiotics of Nicholas Cook, such that it frames the analytical question of how such music is driven by conformance, contest and complementation between multi-media elements in ways that make meaning possible. Accordingly, this methodology resonates with the non-essentialising focus of Foucauldian problematisation, premised on critical resistance that makes new responses simultaneously possible. The self-reflexive autoethnographical approach employed, entailing the author’s dialogical engagement with her own ‘Afrikaner self’, similarly facilitates the dynamic interplay between multiplicities. Correlatively, on the one hand, more ‘closed’ and more ‘open’ Afrikaner identity positions reflected within the songs are analysed, as well as seemingly ‘reconciliatory’ / collaborative’ musical manifestations which ultimately revert back to more ‘closed’ identity constructs. But on the other hand, observation of adherence to a ‘white-black’ dichotomy within songs that manifest more ‘closed’ identity positions also leads to consideration of the parallels between the goals of white Afrikaner Nationalism and the current Decolonisation narrative, which is informed by Black Consciousness thought and generated by the ‘Colonisation of a Special Kind’ ANC policy. Both such Decolonisation rhetoric and the countering rhetoric of the Neo-Afrikaner Protest Movement (NAP) are thus identified as metanarratives, underpinned by a ‘white-black’ dichotomy. In this regard, while Huisgenoot’s predisposition towards songs manifesting more ‘closed’ Afrikaner identity positions is considered in terms of its aforementioned profit-oriented endeavour to appeal to its ostensible primary readership, an encouraging increase in coverage of coloured artists is both noted and occasionally seen to overlap with its coverage of songs manifesting more ‘open’ Afrikaner identity positions. Among the latter one may – again in Foucauldian terms – differentiate between songs focussed on an engagement in cross-cultural relations of power, and songs intent on shattering states of domination of power blocks, often through shocking juxtaposition of disparate elements. These more violently dismantling endeavours, it is argued, comprise examples of Foucauldian transversal struggles, although their coverage in Huisgenoot is also attributed to their shock value and/or record sales, rather than their transformational potential. Furthermore, such Huisgenoot coverage is also seen to place more transformationally oriented artists at risk of media ‘domestication’, with its concomitant inhibiting of creativity. Finally, the researcher’s commitment to creative problematisation of her own Afrikaner identity, coupled with acknowledgement of her inescapable textual entrapment, culminates in her acceptance of the continual flux characterising dialogical power relations, before she – in accordance with the Foucauldian methodology employed – presents all ‘conclusions’ in a non-dictatorial spirit of ‘truth creation’, desirous of continual self/other dialogue. , Thesis (PhD) -- Faculty of Humanities, 2021

- Description: Gavin Maxwell was an author and naturalist. He published a memoir called A Ring of Bright Water, which shaped the way millions of readers viewed nature. Maxwell wrote simple prose which paints an idyllic and moving picture of his time spent in his “lost paradise”, alongside his beloved animals, most notably his otters. However, in reality Maxwell was a man in conflict, seen in volatile relationships, financial recklessness, and the preference for the company of animals over people. The aim of this study was to explore Maxwell’s life to gain insight into his personality development. This was achieved by applying Otto Kernberg’s Object Relations Theory to his life experiences. In doing so the author hoped to gain an understanding of the personality dynamics that led to Maxwell’s relational difficulties and eccentricities. Data was collected by triangulating multiple sources of information on his life. Miles and Huberman’s (1994) three step approach was used to analyse data collected. These steps are: data reduction, data display, and conclusion drawing and verification. The research study found that Maxwell’s personality development was likely arrested at the third stage of Kernberg’s model. Maxwell relied primarily on immature defence mechanisms based in splitting and possessed a fragile ego structure which he protected through grandiosity. The findings indicated that Maxwell’s personality falls in the borderline level of functioning with a strong likelihood of pathological narcissism. , Thesis (MA) -- Faculty of Health Sciences, 2021

- Description: The researcher conducted a sociological investigation into the persistence of child labour in the fishing communities of Uganda, specifically in the Ssese Islands, Kalangala District, on the Kisaba and Nakibanga landing sites situate in Bukasa. The study aimed at investigating the sociological aspects of persistent child labour practices in the fishing communities. The study employed a qualitative research method with a descriptive case study design, utilising an interpretive paradigm. The case study design facilitated the researcher’s investigation into child labour practices in their natural settings. The study employed mainly in-depth interviews, focus group discussions and observations for data collection. Data analysis was performed utilising the ATLAS.ti computer software package to identify the sociological factors involved with employing child labour. The Various themes emerged from the data analysis. The study established that despite the Ugandan Government domesticating all the UN/ILO Conventions on Rights of a Child and Worst Forms of Child Labour, the OAU Charter on Child Rights and Welfare and also instituting legal frameworks at national level, the practice of using child labour persists. The findings disclosed that economic, sociological and structural factors appear to perpetuate child labour in the fishing communities. Economic factors such as poverty, unemployment or underemployment, then sociological aspects such as men abandoning their helpless families on landing sites as they follow the fish according to seasons. Furthermore, the community attitudes such as low value for education, child labour being a normal trend and part of apprenticeship for the children. Again, there are structural issues such as the inadequate implementation and the weak enforcement of the legal frameworks, including insufficient infrastructures such as schooling facilities. These factors appear to perpetuate child labour in the fishing communities. The study concluded that there is an urgent need to address the issues associated with the persistence of child labour in the fishing communities. The study recommends employing a holistic multipronged approach through bottom-up participatory planning and integrating stakeholders at various levels. This could enhance efforts and share ideas and resources that can result in effective operations in order to eliminate child labour in the fishing communities. , Thesis (DPhil) -- Faculty of Humanities, 2021

- Description: Our understanding of the evolution of dune morphology has been hampered by a lack of empirical observations of airflow behaviour over dune forms. Sand dunes intrude into the atmospheric boundary layer and convergence of streamlines results in an acceleration of airflow up the windward slopes of dunes. This study examines the airflow structure and corresponding bedform development on the windward slope of a 7 m high transverse dune on the edge of the Alexandria coastal dunefield, Algoa Bay, South Africa. The Alexandria dunefield is subjected to a trimodal wind regime, consisting of the dominant south-westerly which blows all year round, summer easterlies and winter northwesterlies. The morphology of the study dune, Dune13, is controlled by the easterlies and north-westerlies, and reverses seasonally with respect to these two winds. Seven section lines 30 m apart and normal to the dune crest were surveyed regularly over the period of a year to monitor the reversal process. Three detailed topographic surveys were also done during this period. Airflow behaviour was monitored during the year. Wind speed profiles on the windward slope of the dune were measured using 4 to 5 vertical arrays of anemometers positioned from the base of the dune to the crest on a 1 selected section line. Usually 4 to 5 anemometers were deployed in each vertical array, from a height of 6 to 10 cm above the surface, up to a height of 150 cm above the surface. Initially 8 microanemometers were available; ultimately 28 anemometers were run simultaneously. An independent weather station at an elevation of 6 m recorded the unaccelerated flow. Local gradient measurements and erosion and deposition rates were recorded along selected section lines. Strong summer easterly winds (14 m/sec at 1.4 m above the dune crest) were measured on a dune slope in the process of being transformed from a slipface to a stoss slope. The following winter, light north-westerly winds (typically B m/sec at 1.6 m above the dune crest) were measured on the new windward slope already reversed by the prevailing winter wind. Airflow data confirm the compression of airflow against the windward slope resulting in a non-logarithmic wind speed profile. Compression results in an increased shear velocity within 30 cm of the dune surface, and the dune slope is eroded. Higher up in the wind speed profile, shear velocity decreases to 0.1 m/sec. It is not known at what height the wind speed profile recovers from the intrusion of the dune into the boundary layer. High values of shear velocity (1.6 m/sec) above the rounded crestal area of the dune record the recovery of the wind speed profile from flow divergence, which is a response to the rapid reduction of dune gradient and is accompanied by deposition of sand in this region. 2 The erosion pin data act as a simple and sensitive test for changes in gradient, reflecting the dune's response to changes in the airflow regime. The shape of the dune plays a major role in determining the extent of the compression and the distribution of shear velocity up the slope. Increased shear velocity is experienced on that part of the slope which is nonaerodynamic with respect to the prevailing wind. Under unidirectional conditions, feedback between flow and form results ultimately in a slope with a curvature such that shear velocity increases systematically upslope. The survey data and erosion pin data record the reversal process as the dune achieves a new steady state during each wind season. The existence of a non-logarithmic wind speed profile makes it difficult to know what relevant measure of shear velocity is to be used in sand transport equations. Future work should include wind speed measurements within 10 cm of the surface. An ideal study modelling aeolian bedform development would utilise wind tunnel measurements, combined with field measurements such as obtained in this study, for comparison with numerical modelling. The study needs to be extended to 3-dimensional airflow measurements. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2021

- Description: This thesis explores the distinction between commissioning and curating, adopting the Bienal de São Paulo (or Bienal) as its conceptual propeller and point of departure. The thesis regards exhibitions as palimpsests, in other words, platforms built on previous conscious or sublimated models, beyond the Venetian model inaugurated in 1895. By looking at world expositions, particularly the Cape presence at the Colonial and Indian Exhibition of 1886, this project traces a lineage of commissioners, from Sir Henry Cole to Sydney Cowper through to the Director of the Pretoria Art Museum, Albert Werth. It distinguishes these men, their vision and allegiances from the curatorial model instantiated in South Africa by the late Okwui Enwezor as a consequence of the Second Johannesburg Biennale, held in 1997. The aim of this research has been to provide a partial but crucial account of this shift, and to remain attentive to the silences and deletions, to what happens in the interstice, at transitionary moments of ‘betweenness.’ I ask that readers consider the 1979 Bienal as an instance of an interstice where the occluded and silenced ghost of modernist artist Leonard Tshehla Mohapi Matsoso, who represented South Africa at the 1973 edition of the Bienal, garnering a substantial award for his work in drawing, resides. Matsoso was the first and only Black South African artist to receive this accolade. This thesis posits that Matsoso’s absence from the exhibition in 1979, an exhibition where he would rightly have featured, constitutes a curatorial haunting, wedged in the archive of the Bienal’s history, and an opportunity for revision and evaluation of commissioning vis-àvis curating. In reading the exhibition histories’ archive “along the grain” (Stoler 2002), the commissioner emerges as a man of letters, a privileged social category found in the archive; a colonial authority whose status was founded as much on his display of European learning as on his studied ignorance of local knowledge; an implementer of the taxonomic state and modernist art historical canon (in the case of Werth); a cultivator of the fine arts of deference, dissemblance and persuasion. At a later stage and moment of dissonance and disruption, the independent curator emerges to reconsider, question and expand the canon, distancing him/herself from the (South African) State to serve the artist or artists and a wider community. This research aims to contribute, albeit in a small way, to a reappraisal of the position of Leonard Tshehla Mohapi Matsoso in South African modernism, and the distinction between commissioning and curating. , Thesis (PhD)--Rhodes University, Faculty of Humanities, Department of Fine Art, 2021
