- Description: The study explored smallholder farmers’ perceptions of drought tolerant maize in Cork village, Mpumalanga Province. The study analysed the factors that pushed smallholder farmers to grow drought tolerant maize crops. It examined the maize varieties farmers grow and investigated the benefits and the challenges of growing drought tolerant maize crops. The review of literature found that no similar studies have explored the smallholder farmer’s perceptions of drought tolerant maize. The study was guided by a pragmatic research philosophy and it used mixed research methodology to collect data on the research objectives of the study. Purposive sampling was used to select primary respondents and snowball sampling was used to select key informants. The study found that drought and agro-ecological conditions have pushed farmers to grow drought tolerant maize crops and these crops are improving farmer’s agricultural yields and food security. However, drought tolerant maize crop varieties are inaccessible at shops and they are very expensive to buy given the socio-economic status of people living in rural areas of this village. The study recommends that the price of drought tolerant maize seed varieties should be subsidised, availability and easily accessibility to the market should be improved and future studies could investigate the contribution of drought tolerant maize varieties on household food security. , Thesis (MA) -- Faculty of Business and Economic science, 2022

- Description: Estuaries are historically convenient places to build industries, as it was deemed a suitable place to dispose of large quantities of urban and industrial waste into the ocean. At the time it was judged to be appropriate, as rivers can transport and deposit waste into the ocean, which was considered so vast that it is insurmountable. Therefore, metal pollution in estuaries is a well-known occurrence. Coastal wetlands play an important role in the cycling of metals, and act as effective metal sinks. They provide an important ecosystem service acting as accumulators and phytostabilisers, which make toxic levels of the metals unavailable to the rest of the food chain. The overall aim of this study was to assess the metal pollution in the salt marsh (Salicornia tegetaria and Spartina maritima) and seagrass (Zostera capensis) of the heavily developed Swartkops Estuary. Assessing the metals in the estuary will provide information on effective environmental management strategies. Metal concentrations were measured in the rhizosediment of the three wetland plants, bare sediment, and in the tissues (leaves, shoots, and roots) of the selected plant species. Sampling occurred during one seasonal cycle (2019-2020), and in 5 sites along the middle and lower reaches of the estuary. Metal concentrations were not the highest closest to the point sources in the middle reaches, but the metals rather accumulated downstream in Site 3 (Tiger Bay launch site close to the WwTW) and Site 4 (Tippers’ Creek), which were depositional sites. Although these two sites generally displayed the highest metal concentrations, they also had the most seasonal fluctuations in their metal concentrations and sediment characteristics. Flushing events in spring/summer were likely the determining factor of these fluctuations. The mouth of the estuary (Site 5) consistently had much lower metal concentrations, with distinctly more sandy, low organic content sediment, due to marine-influenced flushing. Thus, spatial differences were distinct in the estuary, however seasonal differences did not play an important role in the metal concentrations, indicating that seasonal sampling was not as important as sampling in different sites. Assessing the metal concentrations in different rhizosediment gave important insights on intertidal accumulation and contrasted with the unvegetated (bare) sediment. The metals generally accumulated more, higher up the intertidal range, due to less frequent tidal inundation and flushing — so that metal accumulated in the vegetation in the following order: Z. capensis > S. maritima > S. tegetaria. Moreover, unvegetated (bare sediment) showed much lower metal concentrations compared to the rhizosediment, indicating that the vegetation trapped small particles, and changes the physical environment to concentrate metals in their rhizosphere. Lastly, the plant species all displayed good accumulation of metals in their roots, while Z. capensis also showed remarkable uptake to its leaves. The study identified S. maritima and S. tegetaria as good phytostabilisers, particularly the latter with its vi high metal stocks and slow root turnover rate. The compartmentalization in these plants were unique to each species, corroborating previous assessments that compartmentalization cannot be compared between similar life forms and genera. These results contribute to local and international research on biogeochemistry in wetlands, and assessment of pollution in developed estuaries. Of note is Z. capensis, an endemic Southern African species, which has not been analysed for compartmentalization of metals before. All three of the studied species have potential as metal accumulators, and therefore a sink of metals. They localize the metals, limiting bioaccumulation to the rest of the food chain, which reduces the ecotoxic effect of metals in the environment. Higher accumulation in vegetated (rhizosediment) over bare sediment, make these habitats valuable metal sinks. This increases their importance in estuaries receiving high pollution loads, and they should be prioritized in conservation efforts. Two sites within the Swartkops Estuary, Tippers’ Creek (Site 4) and the Launch Site (Site 3), are potential sites for long-term monitoring due their capacity to trap and accumulate metals. The results of this study will inform local management on the state of metals in the Swartkops Estuary, providing crucial information on the importance of preserving local wetlands for the purpose of regulating toxic levels of metals in the ecosystem. , Thesis (MSc) -- Faculty of Science, Botany, 2022

- Description: high crime rate in South Africa showed an increase in 2018 with recidivism being the highest contributing factor. The increase in recidivism rates is a result of many factors, including the ineffectiveness of rehabilitation programmes. In an attempt to combat the increase in recidivism, its causes have been examined from a number of perspectives, especially social factors. However, very few studies have focussed on psychological factors when studying crime in South Africa. International studies have found personality factors to be a contributing factor towards recidivism. Concordantly, international studies have also established a correlation between early maladaptive schemas, a core component of personality, and crime. This study aimed to explore early maladaptive schemas among reoffenders in Gqeberha, South Africa. The objective of the study was to establish the prevalence of EMS in a sample of repeat offenders from the National Institute for Crime Prevention and the Reintegration of Offenders (NICRO) in Gqeberha. The study used a quantitative methodology and a sample size of 14 participants was utilised. Convenience sampling was utilised to identify reoffenders. The data was collected by administering a short demographical questionnaire and the Young Schema Questionnaire (YSQ). Descriptive statistics and Spearman’s correlations were utilised to analyse the data. , Thesis (MA) -- Faculty of Health Sciences, 2022

- Description: Environmental Health Practitioners (EHPs) play a vital role in providing and facilitating comprehensive proactive environmental health-related services to promote a safe, healthy and clean environment and prevent diseases. The National Environmental Health Policy (South Africa. Department of Health, 2013) referred to environmental health services as critical preventative health services that require adequate financial, human and material resources to significantly contribute to addressing the development goals. South Africa currently faces a quadruple Burden of Diseases (BoD), consisting of HIV and AIDS and TB, High Maternal and Child Mortality, Non-Communicable Diseases and Violence and Injuries, and, more recently, the COVID-19 pandemic. The contributing factors to environmental-related diseases in South Africa include poor hygiene and sanitation practices due to lack of adequate sanitation facilities, poor management of waste, pollution of water and contaminated ambient air. The National Environmental Health Policy, 2013, described the importance of Environmental Health practice in the prevention and reduction of the incidence of diseases emanating from environmental factors, with a strong focus being on communicable diseases. The aim of the study was to examine the role played by EHPs in the epidemiological surveillance of diseases, in particular the prevention and management of Legionnaires’ disease, in one of the municipalities in the Eastern Cape Province. The study, which followed a mixed methods approach, was divided into two phases- phase 1 and phase 2. Phase 1 of the study employed a quantitative method of data collection where EHPs from the Municipality participated in a questionnaire survey, while phase 2 of the study followed a qualitative method of data collection where members of the Outbreak Response Committee from the District H participated in the focus group interviews. EHPs are represented in the Outbreak Response Committee of District H where they play a significant role in the prevention and management of diseases. Data from the questionnaire survey was analysed using the Statistica software programme where descriptive statistics and Spearman’s correlation test were performed. ix Focus group interviews were transcribed verbatim and an independent coder was used to analyse quantitative data from which three themes emerged. The study revealed the unavailability of programmes for prevention and management of Legionnaires’ disease in the Municipality. EHPs and members of the Outbreak Response Committee were found to have uncertainties related to their role in the prevention and management of Legionnaires’ disease. The study further depicted that the involvement of participants in both phase 1 and phase 2 in managing Legionnaires’ disease in their respective areas, is influenced by external factors such as the unavailability of programmes and systems to monitor, prevent and manage Legionnaires’ disease, shortages of staff, financial implications and capacity building. Lastly, the challenges encountered by the EHPs and members of the Outbreak Response Committees should be addressed by their respective managers to improve their response towards prevention and management of Legionnaires’ disease. , Thesis (MA) -- Faculty of Health Sciences, 2022

- Description: The study investigated the effect of sovereign credit rating on the banking sector in South Africa. Four different models with different measures of the banking sector were used to investigate this effect. In the first model Tobit model was used to analyse the effect of sovereign credit rating on bank ratings in South Africa. The study found that sovereign credit ratings have a significant positive effect on bank credit ratings. Using GMM with a sample of 11 banks, with bank lending as the measure for the banking sector, the study found that sovereign credit ratings (SCR) have a positive and significant effect on bank lending by commercial banks in South Africa. The study also used net interest margin, a measure for bank profitability as a third proxy for the banking sector and found that sovereign credit ratings have a significant positive effect on bank profitability. Furthermore, the study used bank stability measured by Z-Score to assess the effect of sovereign credit rating on the banking sector in South Africa. Taking a different approach and using ARDL, the study found that SCR has a positive long-run relationship with Z-Score. Based on the findings in all four models, the study concluded that the sovereign credit rating has a positive and significant effect on the banking sector in South Africa. This means that the sovereign credit ratings upgrade will lead to an improvement in the banking sector. A sovereign credit rating downgrade will be detrimental to the banking sector in South Africa. The study has shown that there are interlinkages between the public and the private sector; therefore, government must come up with strategic policies to ensure stability and reduction of government debt. Policymakers of the banking sector should also strengthen policies that will ensure banks remain profitable and stable even during a sovereign crisis. An effective and efficient asset management is important for the survival of South African commercial banks. The study recommends that both the private and public sector should work in cooperation when formulating policies so that the impact of the regulatory measure on commercial banks is taken into consideration. , Thesis (PhD) -- Faculty of Business and Economic science, 2022

- Description: This thesis examines contestations around access to state-provided housing or simply state housing in South Africa, using a case study of two sites in Buffalo City Municipality, and with a particular focus on occupation without ownership through informal and illegal means. While the South African state, based on an official human rights discourse and regime, seeks to provide state housing to the urban poor, massive housing backlogs continue to exist within urban spaces. As a result, the urban poor turn to self-provisioning through the construction of informal settlements or backyard shacks, waiting at times indefinitely to be allocated a state house via the official housing waiting lists. To overcome this problem, some amongst the urban poor opt to circumvent the process by invading and illegally occupying state houses, leading to occupation without ownership. In doing so, they draw upon their own moral rights-claims to justify their actions. The thesis examines the multiple causes for occupation and ownership contestations in the two research sites as well as the different forms that these contestations take. The study is framed theoretically in terms of a sociology of human rights, identifying and analysing how moral claims to rights amongst ordinary people often come into conflict with a legal-institutional conception of rights adopted by the state. The study also draws on a diverse array of theorists whose work speaks to the manner in which ordinary citizens develop their own ways of acting contrary to state officialdom. Using interpretive sociology, the study considers the views and practices of those illegally occupying houses without ownership and those who feel victimised by these informal actions. It considers these intra-community dynamics in light of the machinations of local state powerholders at municipal level. As with interpretive sociology, then, the thesis privileges social realms of meanings, interpretations, experiences and practices of human agents. Informal state housing occupations in the Buffalo City Municipality are caused by a number of factors related to state incapacity, weak policies and poor planning, corruption, resource constraints and so on. The study vividly demonstrates the tensions arising and existing between the South African state’s legal human rights regime and locally-constructed moral-rights regimes amongst the urban poor. This tension is seen in the interrelated phenomena of ‘occupation without ownership’ and ‘ownership without occupation’, as the poor draw upon and use ordinary logics of rights for recourse. The thesis shows how diverse rights regimes lead to intra-community conflict, in particular along generational and racial lines. , Thesis (PhD) -- Humanities, Sociology, 2022

- Description: The Albany Thicket Biome has undergone extensive degradation over the past century, particularly from overstocking of livestock in the arid types of thicket. The degradation of the biome, coupled with little to no natural recovery, prompted the South African Government to implement the Subtropical Thicket Restoration Programme (STRP) in the early 2000s to rehabilitate degraded thicket using unrooted Portulacaria afra truncheons. The STRP also sought to create job opportunities, bring about social upliftment, promote biodiversity conservation and incentivise farmers and landowners in the region to promote carbon trading and farming of P. afra using carbon credits. However, the survivorship of P. afra planted using the STRP planting protocol has been less than ⁓30% because they are planted in degraded areas, where the truncheons are subjected to harsh biophysical conditions such as hard, capped soil, high soil temperatures, drought and herbivory. The aim of this study, therefore, was to improve the survivorship of P. afra planted in degraded thicket to at least 30%, using modified planting methods. In this study, four treatments were applied in 210 pondings (or micro-dams), each with P. afra planted in them (the first three treatments used rooted cuttings). The first treatment involved watering regimes where pondings were watered at varying frequencies. The second treatment involved planting companion species alongside P. afra while the third treatment involved planting P. afra underneath a nurse canopy. In the fourth treatment, unrooted P. afra truncheons were planted inside pondings. The mean survivorship of the P. afra cuttings was assessed 18 months after planting. The watering regime treatments, including the control, all yielded a survivorship of over 75%, with the significantly highest levels of survivorship being displayed in the weekly watering treatment (90.9 ± 6.8%) (p < 0.01). The companion plant treatment also produced a high mean survivorship of P. afra (94.9 ± 3.6%), significantly higher than that of the nurse plants (87.5 ± 6.3%) (p < 0.01). Among the unrooted truncheons it was found that untreated truncheons had the highest survivorship (76.2 ± 17.6%), with the lowest mean being found in truncheons that were both pruned and scarified (70.8 ± 20.8%), suggesting that this treatment, out of all of them, is the least successful under the prevailing environmental conditions in the study area. However, there was no significant differences among the unrooted truncheon treatments and their respective survivorship values to further substantiate this assertion (p = 0.26). Findings in this study also suggest that planting P. afra cuttings under a nurse plant was ideal for P. afra survivorship due to the nurse plant’s ability to ameliorate the microclimate under which the cuttings can establish and grow. Despite the soil under the nurse canopy having a significantly lower mean soil water potential (-160.9 ± 200.5 kPa), compared to the open areas (-73.4 ± 55.7 kPa) (p = 0.04), the pondings under the nurse canopy still had a lower mean soil temperature (31.4 ± 5.25°C) than the treatments in the open areas (38.5 ± 2.7°C), during the harsh midday sun. These favourable characteristics are reflected in the P. afra cuttings under a nurse canopy having a higher chlorophyll fluorescence (0.76 ± 0.06). compared to those planted in open areas (0.73 ± 0.13), suggesting that the P. afra cuttings in the former treatment had a higher photosynthetic efficiency compared to those in the latter, despite there being no statistically significant difference in chlorophyll fluorescence between the treatments (p = 0.14). Although these findings suggest that applying these modifications to planting P. afra, having achieved its objective of increasing survivorship to well over 50%, is likely to produce favourable results not only in overall survivorship, but also in fast-tracking arid thicket rehabilitation and restoration, further research on these rehabilitation techniques and their effectiveness is required. Furthermore, the downside to these treatments is that they are costly and time consuming, which puts the feasibility of large-scale programmes using these applications into question. Further investigation is required to determine ways in which the cost-effectiveness of these applications can be enhanced. , Thesis (MSc) -- Faculty of Science, Environmental Science, 2023

- Description: The Albany Thicket Biome has undergone extensive degradation over the past century, particularly from overstocking of livestock in the arid types of thicket. The degradation of the biome, coupled with little to no natural recovery, prompted the South African Government to implement the Subtropical Thicket Restoration Programme (STRP) in the early 2000s to rehabilitate degraded thicket using unrooted Portulacaria afra truncheons. The STRP also sought to create job opportunities, bring about social upliftment, promote biodiversity conservation and incentivise farmers and landowners in the region to promote carbon trading and farming of P. afra using carbon credits. However, the survivorship of P. afra planted using the STRP planting protocol has been less than ⁓30% because they are planted in degraded areas, where the truncheons are subjected to harsh biophysical conditions such as hard, capped soil, high soil temperatures, drought and herbivory. The aim of this study, therefore, was to improve the survivorship of P. afra planted in degraded thicket to at least 30%, using modified planting methods.

- Description: Diabetes mellitus is recorded as a significant health crisis in South Africa and various medicinal plants are used for the management of diabetes. However, the chemistry and bioactivity associated with these plants' antidiabetic activity are still lacking. Cissampelos capensis L.f. and Strychnos henningsii Gilg are among the plants utilised to manage diabetes in the Eastern Cape Province, South Africa. C. capensis and S. henningsii are known for their isoquinoline – and indole alkaloids, respectively. Other phytochemical groups associated with antidiabetic activity are the phenols, flavonoids, and terpenes. Thus, this study aimed to evaluate in-depth the phytochemical profiling, alkaloidal identification, and structural characterisation of phytochemicals isolated from these plants. Also, subsequent in vitro antidiabetic screening of the crude extracts and isolated compounds from both plants was done. The phytochemical profiling was performed by employing a qualitative and quantitative approach through high-performance thin layer chromatography (HPTLC) and UV-spectrometry. Further analysis for the identification of alkaloids was done by using LCMS. Fractionation and purification of crude extracts were achieved through crystallisation and various chromatographic techniques. NMR, HRMS, UV/Vis, FTIR, and XRD spectroscopic techniques were used to characterise isolated compounds. In vitro antidiabetic activity screening involved the investigation of cytotoxicity, antioxidant activity, alpha-amylase – and/or alpha-glucosidase inhibition (particular to type II diabetes). C. capensis and S. henningsii extracts tested positive for alkaloids, phenolics, flavonoids, and terpenes through HPTLC screening. Quantitative estimation by UV spectrometry of these phytochemical groups detected the highest concentration of alkaloids, followed by flavonoids, phenolics, and terpenes content. The in vitro antidiabetic biological screening of the various crude extracts suggested that the presence of alkaloids, flavonoids, phenolics, and terpenes fostered favourable biological activity. The LCMS of the known alkaloidal constituents from C. capensis detected the presence of ten alkaloids, including glaziovine, lauroscholtzine, pronuciferine and vi salutardine. Seven known alkaloids and one triterpene were detected from S. henningsii, including holtsiine, 23-hdroxyspermostrychnine, henningsiine, and the triterpene, friedelin. These findings suggest that C. capensis and S. henningsii have similar phytochemical constituents compared to the species reported in literature. However, the distribution of the phytochemicals in the various plant parts differed from previous accounts. , Thesis (PhD) -- Faculty of Science,School of Biomecular and Chemical Sciences , 2022

- Description: The influence of urbanization and industrialization on natural resources results in complex water resource management. In South Africa, there has been escalating rural-urban migration, a growing population in urban areas, and the mushrooming of informal settlements in cities over the last five decades. In the pursuit of protecting water resources, these contextual realities create a significant challenge to policymakers, planners, and implementers. Due to rapid population growth, climate change, recent droughts, and growing competition among agricultural, industrial, commercial, environmental, and domestic sectors, water resources are presently under severe stress in South Africa. This situation necessitates the effective management of water resources. This study completed a situational assessment for the Swartkops Catchment to examine the extent of pollution, mapped sources of pollution, investigated water quality governance and identified hot spot areas to provide the foundation for effective and efficient catchment management. To determine the current water quality status of the Swartkops Catchment, this current study investigated spatial and temporal variation in physico-chemical parameters, nutrients, and faecal bacteria. This study applied a mixed-method research design using semi-structured interviews and focus groups discussions as data collection methods to investigate the water quality governance of the Swartkops Catchment. Following the situational assessment of the Swartkops Catchment, the effectiveness of applying innovative smart catchment practices to improve water quality was investigated. The word smart in this context refers to innovative mechanisms that will ensure effective and efficient water resources management. The PHP scripting language (Hypertext Preprocessor), Android studio, Wampserver, and JavaScript were used to develop the Water Use Screening System (WUSS) and Pollution Incident Reporting System (PRS). In South Africa, stormwater infrastructure suffers from unsustainable utilization. Stormwater systems discharge into many of the country‘s rivers and estuaries, including Swartkops, leading to water quality degradation. To improve the Recommended Ecological Category (REC) of the Swartkops Estuary to Category C, drivers that contribute to poor water quality must be understood to inform appropriate management interventions. Results from sampling in Markman Canal were compared with historical water quality data. The present study showed that the Markman Canal contributed faecal bacteria, nutrients, and trace metals to the Swartkops Estuary. The Markman Canal was the greatest source of trace metals to the Swartkops Estuary compared to the other point sources entering the estuary. The results show that arsenic and mercury levels in the Markman Canal and the Swartkops Estuary were higher than that previously measured. Iron and copper concentrations were higher in the Markman Canal whereas only copper increased in the Swartkops Estuary. , Thesis (PhD) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: Food insecurity is a prevailing problem and according to a report released in 2019 by the Food and Agriculture Organization (FAO), about 2 billion people in the world experience moderate or severe food insecurity (FAO, IFAD, UNICEF, WFP and WHO 2019: vii). Consequently, if we are to make a significant change in these statistics, the actions taken to “tackle these troubling trends will have to be bolder, not only in scale but also in terms of multisectoral collaboration” (2019: viii). It is against this backdrop that this study will explore the discursive landscape around four social media applications - OLIO, Too Good To Go (TGTG), KHULA and OneFarm Share - working to fight food waste, tackle food insecurity and reimagine the food system. This study is situated in the field of media studies and adopts a qualitative approach, with hermeneutics as the specific research strategy which “[seeks] understanding, rather than to offer explanation” (Kinsella 2006: n.p). This study maps the development of media effect theories over the years and explores where it is today, drawing on key thinkers in the space of new media including Lister, Manovich and Castells. This is followed by a discussion of food insecurity globally, and then locally within a South African context, as well as through the lens of ecosocialism drawing on voices such as Kovel and Löwy. This will lead to a content analysis of the four selected applications exploring the discursive landscape around each, and what similarities and disparities emerge. , Thesis (MA) -- Faculty of Humanities, Language, Media and Communications, 2022

- Description: Over the last few decades since the independence of most African countries, which coincided with that of Asia, the economic growth between the two continents has not been the same. As an example, in the year 1965, exports and incomes per capita were much higher in Ghana compared to Korea and it was anticipated that this trend would continue into the future. But these projections were shown to be way off the mark as Koreas’ exports per capita overtook Ghana’s in 1972, and its income level surpassed Ghana’s four years later. Between 1965 and 1995 Korea’s exports increased by 400 times in current dollars. Meanwhile, Ghana’s increased only by 4 times, and real earnings per capita fell to a fraction of their earlier value (World Bank, 2000). This raises questions regarding the tools available for use in the pursuit of economic growth. This study then attempts to examine the role of institutional quality in moderating the impacts of fiscal policy on economic growth in sub-Saharan African economies. Objectives of the study firstly included the investigation of the effect of fiscal policy on economic growth, it then explored the effect of institutional quality on economic growth which was then followed by the analysis of whether the impact of fiscal policy on economic growth is dependent on institutional quality. This dissertation employs the Generalised Method of Moments to analyse the effect of fiscal policy on economic growth given institutional quality for sub-Saharan African countries for the period from 1996 to 2018. The findings show that the conduct of fiscal policy under improved institutional quality positively and significantly improve sub-Saharan African countries output. SSA countries should strengthen independent institutional bodies that prosecute economic crimes through employing participatory and transparent decision-making processes. Citizens should have freedom of association, expression and a free media. Also, African countries should support African agendas that are aligning with global development agenda. Sub-Saharan African countries should strengthen institutions that widen democratic space, civil liberty and the participation of citizen in the development agenda of a country. , Thesis (MA) -- Faculty of Business and Economic sciences, 2022

- Description: imbabwe's socio-economic development crisis revived citizen agency and birthed several social movements. The purpose of this study is to investigate the challenges that social movements face in holding the Zimbabwean government to account for Zimbabwe’s crisis. Three social movements, Occupy Africa Unity Square, #Tajamuka/Sesjikile and #ThisFlag were selected for in-depth qualitative inquiry. The study examined their activities between 2013 – 2020 during which time they were the most prominent social movements in Zimbabwe. Primary data was derived from social media and key informant interviews. Secondary data was derived from a desktop review of textbooks, commentaries, social movement documents, journal, and online newspaper articles. Using the Thematic Data Analysis technique, data was organized into three themes namely the socio-economic challenges faced by Zimbabweans, the role played by social movements to bring the Zimbabwean government to account for the socio-economic development crisis and the challenges social movements encountered in the process. The Critical Discourse Analysis (CDA) found that social movements collectively engaged in protest action, lobbying, shutdowns, and legal action to make the government accountable for socio-economic injustices. In exacting government accountability, Zimbabwean social movements encounter the challenges of overreliance on social media, limited civic space, a decline of social movements, individual centered movement leadership, disengaged citizenry, absence of strategic plans, an uncooperative government and disunity amongst activists. This study recommends social movements’ leaders to develop protracted strategies for mobilisation beyond urban centers. It also recommends that movements prioritise socio-economic reforms and development projects which bring material benefits to citizens as these are more likely to be realised in the immediate future as opposed to political reforms. To revamp the Zimbabwean economy, the study recommends the citizens of Zimbabwe to be more actively involved in the affairs of their country, the armed forces to establish strong institutions and reconsider the role they should play to ensure socio-economic or political transformation and the government to demonstrate political will to deal with the crisis in Zimbabwe by instituting political reforms. , Thesis (MA) -- Faculty of Business and Economic science, 2022

- Description: imbabwe's socio-economic development crisis revived citizen agency and birthed several social movements. The purpose of this study is to investigate the challenges that social movements face in holding the Zimbabwean government to account for Zimbabwe’s crisis. Three social movements, Occupy Africa Unity Square, #Tajamuka/Sesjikile and #ThisFlag were selected for in-depth qualitative inquiry. The study examined their activities between 2013 – 2020 during which time they were the most prominent social movements in Zimbabwe. Primary data was derived from social media and key informant interviews. Secondary data was derived from a desktop review of textbooks, commentaries, social movement documents, journal, and online newspaper articles.

- Description: This study explores the nature and scope of food insecurity among postgraduate students at Nelson Mandela University, South Africa. The study employed a mixed method approach to access postgraduate students and university officials to investigate the prevalence of food insecurity. The approach also assesses the demographic factors; academic and mental implications along with the coping mechanisms associated with the experiences of food insecurity in higher education South Africa. The study incorporates an adapted conceptual framework from Alaimo’s food insecurity socio-economic risk models (2005) to understand the higher education context. Alaimo’s model seeks to connect the household conditions and broader systematic socio-economic mechanisms that households adopt to secure food. This model was adapted and employed in understanding the data collected while using a mixed-method approach between June and August 2021. The study employed an online survey for only postgraduate students enrolled at Nelson Mandela University (NMU) during the time of the study. This was supplemented by semi-structured interviews with student affairs officials that are directly involved in the formulation of strategies used to alleviate food insecurity at NMU. With 78 postgraduate students responding to the online survey, the study seems to confirm some of the studies done in this field on the inadequacy of food banks and food gardens in addressing food challenges effectively on campus. Similarly, the study found that the experiences of food insecurity were prevalent amongst postgraduate students that identified as black, low-income, and making access of the campus clinic for food relief. The study concluded by recommending a collaborative and a multi-level systematic approach in alleviating food insecurity in higher education. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2022

- Description: This study investigated the perceived impacts of Swartkop Nature Reserve on community livelihoods in Motherwell, Gqeberha in the Eastern Cape of South Africa. The study was motivated by tons of litter and rubble due to neglect of the nature reserve by the community and the municipality. These problems have the potential to cause pollution and ecological degradation. The study was therefore pursued to understand the reasons behind the neglect of the nature reserve, determine how the community is involved in governance and management of the nature reserve and analyse their perceptions about the impact of Swartkop Nature Reserve on their livelihood and community development. The qualitative research methodology was utilised and primary data obtained through self-administered unstructured interviews with thirty-two participants. The participants of the study were from the community of Motherwell; particularly residents of wards 6, 7 and 9. These residents were chosen because of their proximity to the nature reserve and the fact that they are more affected than any other ward that is not as close to the nature reserve. The study found that lack of education and awareness, lack of collaboration between the community and municipality, lack of activism among residents, poor upbringing of some participants are some of the reasons that have contributed towards littering and illegal dumping. Furthermore, failure by the municipality to provide services to the community, especially in collecting refuse and provision of designated landfill, was another finding about what has contributed to the littering on the nature reserve. In terms of impact on livelihoods, the study revealed several activities such as farming, harvesting of medicinal plants, recreational activities, recycling and fishing which could enable the community benefit from the nature reserve. Based on the findings, the study recommends a redeclaration of Swartkop Nature Reserve to incorporate heritage and culture as predominant activities that should take place. Furthermore, it is recommended that the municipality should strive to halt the expansion of the informal settlement and illegal dumping of refuse and rubble in the nature reserve as these are major risks that threaten the biodiversity of the nature reserve. A partnership was proposed between the municipality and the community vi through its Community Trust and Ward-Based Cooperatives as consultative platforms. This partnership between the municipality and community should champion the conservation of the nature reserve which will include reserve management planning, fencing and security, law enforcement, rehabilitation, reintroduction of animals and socio-economic development to create employment and entrepreneurial opportunities for the community of Motherwell. , Thesis (MA) -- Faculty of Business and Economic science, 2022

- Description: Social media technologies are ubiquitous and have become essential information and communication technology applications for society. These technologies provide end-users with the experience of interacting with different social media platforms and socialising with other end-users on these platforms. They also contribute towards the personal development of end-users and the development of the social media community, which has become an important part of their everyday lives. As social media technology evolves, measuring end-user engagement becomes challenging. In the existing literature, the measured engagement, such as the end-user’s activities, typically represents an aspect of the experience that the end-users have with the technology. This view is a single dimension of the end-user’s engagement and, at the same time, a limited representation of the actual interaction the end-users have with the technology. In addition to the behavioural aspect, other dimensions that occur during the interaction are the emotional and cognitive aspects. Together, these three aspects of end-user engagement occur simultaneously during the interaction period. Therefore, there is a need to define and design a broader view of the end-user’s engagement with social media technology. The main research objective of this thesis is to develop an artefact that informs the design of social media technology based on the knowledge or understanding of the end-user’s perspectives of the emotional, cognitive, and behavioural aspects when engaging with social media technology. Also, this study has three sub-research objectives. The first sub-research objective is to define end-user’s engagement and interaction using a concept called User experience engagement and interaction. This concept is proposed to holistically represent the three-dimensional engagement that end-users have with social media technology. The second sub-research objective is to identify an approach to derive some design guidelines and heuristics for social media technology engagement and interaction. The third sub-research objective is to determine how to constitute the end-users experience and design elements into a method. Moreover, this study follows a design science research paradigm. This approach, which combines a literature review, a case study, and an illustrative scenario, was used in the research process to achieve the three sub-research objectives. Specifically, the literature viii review and the case study focus on defining the end-users’ emotional, cognitive and behavioural engagement with social media technology. Findings were used to interpret end user engagement and develop the design method that would aid designers and developers to enhance end user engagement and interaction with social media technologies. , Thesis (PhD) -- Faculty of Engineering, the Built Environment, and Technology, 2022

- Description: The purpose of this dissertation is to explore the notion of skin, its functions, and dysfunctions as the basis for the conceptual as well as theoretical output of this work. The problem statement aims to establish whether cathartic relief can be achieved through the process of visualizing skin as the abject other. Every human and animal is born with skin. The epidermis is the outermost of three layers that make up the skin. This layer provides a barrier to infection from environmental pathogens and regulates the amount of water released from the body into the atmosphere through trans epidermal water loss (Bouwstra, 2003:34). Although the human skin serves as a protective barrier, the skin itself can be a source of physical as well as emotional pain. I was born with Epidermolysis Bullosa (EB), a rare and genetic skin condition that results in extensive blistering and wounding of the skin caused by mechanical trauma. The process of friction, wounding and healing has been a part of my physical being and daily affairs since I can remember. According to Cervero, ―Pain is our most powerful emotion, an essential learning tool, a major factor in our relationship with the world, and the source of much of our social behavior‖ (2012:34).I believe that my personal experience with EB has affected how I view the functions and importance of skin. In this study I explore the purposes and functions of skin through both a physical and psychological lense I also investigate the role skin plays in forming identity. The works of artists such as Frida Kahlo, Eva Hesse and Alina Szapocznikow are carefully considered in understanding different approaches and mediums used in engaging with the experience of catharsis. Investigations are made into theories on Abjection, the Skin-Ego, Materiality and Catharsis in order to sufficiently inform and shape the outcomes of the creative process. The creative and research processes have resulted in the body of artwork, entitled Skin- deep: transforming dysfunction into function, which is presented as a narrative installation and exhibition of abstract sculptural work. Ultimately, the body of work and research attempts to validate that the notion of skin (as the abject other skin) can be artistically explored to achieve cathartic relief. , Thesis (MA) -- Faculty of Humanities, School of Visual and Performing Arts, 2022

- Description: Background: “Linkage to care” is an essential strategy in place for the retention of HIV diagnosed clients on treatment. It is vital throughout the management and care of an HIV client. Aim of the study was to explore the effectiveness of “linkage to care” of HIV clients following the diagnosis in the Engcobo sub-district, Eastern cape. Methodology: Qualitative, explorative, descriptive study design was used to explore and describe the effectiveness of “linkage to care” of HIV clients following diagnosis in the Engcobo sub-district. The population for the study were all healthcare workers, who are involved in the program of “linkage to care” of HIV positive clients. Purposive Sampling was used to select professional nurses, Community healthcare workers, Lay counsellors, linkage officers who are involved in the linkage of HIV positive patients and the facility managers whom their facilities provide HIV care services. Interview guide was used to collect data and Tesch’s method was used to analyse data. Findings: Themes that emerged from the study were flexible time to “linkage to care”; use of different policies; administration; team activities and “linkage to care” benefits. Recommendations: Training on “linkage to care”; case management model; TIER.NET system upgrade/ linkage App development, patient information packs; standardised extended hours; transport assistance/outreach mobile services. Conclusion “Linkage to care” is a team effort, it needs collaboration and knowledge. Despite the implementation of a linkage program, there are challenges that the department of health needs to act on as addressed on researcher’s recommendations. , Thesis (MPA) -- Faculty of Health Sciences, 2022
