- Description: Globally social media has shown unprecedented levels of adoption and Social Media Analytics (SMA) is a rapidly growing topic. For governments, SMA holds the promise of providing tools and frameworks to collect, monitor, analyse and visualise social media data, usually driven by specific requirements from a target application. However, social media data is noisy and unstructured, and organisations struggle to extract knowledge from this data, and convert it into actual intelligence. This study argues that SMA can support intelligent decision-making for Citizen Relationship Management (CzRM). CzRM is a growing effort of governments around the world to strive to respond rapidly to their citizens by fostering a closer relationship thereby creating more effective and efficient service delivery. However, there is a little evidence in literature on empirical studies of any existing decision-making framework for CzRM and SMA adoption. In particular, there is a gap with regards incorporating SMA into decision-making for CzRM of governments, particularly in developing countries like South Africa. The aim of this study was to develop a framework that provides guidelines, including methods and tools, incorporating SMA into decision-making for CzRM in the Gauteng Provincial Government (GPG) and the Free State Provincial Government (FSPG) of South Africa. A Systematic Literature Review (SLR) and conceptual analysis method was conducted to design the Social Media Analytics Framework for Decision-making in the context of CzRM (the SMAF). The findings from the literature review revealed several benefits and challenges with SMA, in particular the shortage of skills, guidelines, methods and tools for SMA. These challenges were used to draft guidelines that were included in the framework, which consists of five components that can be used to derive intelligent information from SMA. The pragmatic philosophy and a case study design was used to generate an in-depth, multifaceted understanding of the underlying problems in the case of the GPG and the FSPG. The German North-West Metropolitan region was used as a third case study to provide a more global perspective and a case of a developed country in terms of Gross Domestic Product. The scope of the study was limited to social media posts by provincial citizens related to CzRM and service delivery. Both formative and summative evaluations of the proposed theoretical framework were conducted. The formative evaluation was conducted v | Page as an Expert Review to receive feedback of the framework from the experts in the field of Computer Science and Information Systems. The findings validated the framework and some minor improvements were made based on the experts’ recommendations. Focus Group Discussions (FGDs) with participants from government managers and decision makers in the three cases were conducted. Case documents for the three cases were collected and reviewed. All collected data was analysed using the Qualitative Content Analysis (QCA) method and common categories and themes were identified. Summative evaluations were conducted in the form of a Field Study, which consisted of an analysis of Twitter data from the three cases, and a closing FGD with Business Intelligence (BI) experts at the primary case of the e-Government department of the GPG. The findings revealed that SMA has been adopted in all three cases; however, while their strategies are comprehensive their implementations are very much in their early stages. The findings also highlighted the status of SMA in government and some potential gaps and areas for implementing the framework. , Thesis (PhD) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2022

- Description: Aim This study aims to provide an understanding and a description of the short-term postfire regeneration and ecology of the fynbos-thicket vegetation on a coastal dune system in the southeastern Cape Floristic Region. Another aim is to assess the recovery of the vegetation community by assessing the growth forms and the disturbance response across a range of species from thicket and fynbos communities and to provide a belowground bud bank classification for each of these species in the coastal dune systems. Location The study site was the Mandela University Reserve and the Noordhoek dune fields, situated in Gqeberha, Eastern Cape, which is part of the south-eastern Cape Floristic Region. The study site hosts thicket-fynbos mosaic vegetation type that occurs in a Mediterranean-Climate Ecosystem (MCE). Methods Firstly, field observations and photographs of plant species were taken weekly to assess and identify the species that were emerging and persisting in the dune system in the first 12 months postfire. Phenological events of the species that emerged (e.g., flowering, fruiting, leaf growth, leaf yellowing, and leaf abscission) were also observed and reported on. Secondly, an excavation of 21 species (e.g., Jamesbrittenia microphylla, Euclea racemosa, Olea exasperata, Searsia laevigata) was conducted to classify the species into their belowground bud bank types. Results There was a rapid emergence of resprouters (facultative resprouters and obligate resprouters) in the first 12 months postfire. This was followed by their growth; primarily occurring after the rainfall events. The dominant resprouting species (facultative resprouters and obligate resprouters) entered the system two weeks after the fire. There was a significant difference in the time to the first emergence of the different regeneration groups postfire (P < 0.001): on average, obligate sprouters (OS) appeared 1 month after fire – two months earlier than facultative sprouters (FS) and four months earlier than non-sprouters (NS). There was no statistical evidence to suggest that the FS and non-sprouters NS emerged at different times postfire; however, most NS species were observed in the system 5 months after fire. 4 Exceptions were the NS species Pelargonium grossularoides and Mesembryanthemum aitonis, both annuals that emerged 1 month after fire. A wide range of OS species that appeared earlier in the system (e.g., Euclea racemosa, Olea exasperata, Searsia laevigata, and Lauridia tetragona) exhibit underground lateral growth with belowground bud banks (BBBs) from which they recover after disturbance. In total, six BBB types were recorded in this study, namely: bud-bearing root, rhizome, rhizophore, woody rhizome, stem tuber, and corms. The bud-bearing root from woody species was the dominant BBB in this system. Main conclusion The return of species that occurs in the first year after fire occurs rapidly in the first 2 months as resprouting species (primarily OS) appear in the system. Following this, the rate of return of species decreases as reseeding species (primarily NS) gradually reestablish and occupy the gaps in the dune fynbos-thicket vegetation. This study has shown that plant species in this ecosystem are adapted to fire disturbance as their populations are able to reestablish through various regeneration strategies, including resprouting from different types of BBB. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: The Eastern Cape Karoo in South Africa has been earmarked for potential Shale Gas development, which has necessitated the understanding of existing ecosystems to be quantiĄed pre-development, in order to have a baseline against which the exploration can be monitored. Termite mounds as baseline mechanisms, are known to be sensitive to ecosystem disturbance and because of their abundance in the exploration zone, have been studied as indicator species. They are both a surface and subsurface phenomena which makes them an ideal baseline monitoring mechanism. Termite mound height, basal circumference and geospatial data was collected against natural and anthropogenic factors: elevation, vegetation, water, soil, geology, human settlements and roads. Mound distributions were observed across four study sites, and seven plots, using a DJI Phantom 4 Pro drone, an aerial and ground survey. Observed mound data on the drone and aerial survey was compared to that of the ground survey. Overall, the drone survey outperformed the aerial survey in recording accurate termite mound data. This was largely attributed to the scale of the study which gave the drone a competitive advantage. It allowed for drone data to be collected at 40 m altitude with an image resolution of 2-6 cm/pixel on each plot. In addition, drone detection accuracy was improved through the ability to generate digital surface models (DSMs) through point clouds and overlaying them with orthomosaics. Considering observed mound spatial point patterns, both the drone and aerial survey were more than 50% percent consistent with the ground survey, although the drone survey detected 28.57% more accurate mound spatial point patterns than the aerial survey. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: Current unprecedented environmental changes threaten food web and ecosystem stability, which is particularly concerning in areas with vulnerable species such as the endangered African penguin Spheniscus demersus. In this study I adopted a holistic approach integrating many ecosystem levels to better understand African penguin behavioural ecology and food web stability. I investigated interplay between physico-chemical parameters and zooplankton functional diversity at various temporal and spatial scales in Algoa Bay. The study further investigated the applicability of zooplankton functional diversity (FD) in inferring African penguin food web stability by comparing the FD of zooplankton found in anchovies regurgitated from African penguins and the ones found in the Bay PELTER Stations. Gut contents of anchovies regurgitated from Bird Island and St Croix penguins were also evaluated using Frequency of Occurrence and Dominance methods and compared between colonies. Zooplankton FD in Algoa Bay varied over time but not at spatial scales with chlorophyll-a, Sea Surface Temperature (SST), turbidity and salinity being potential drivers of zooplankton FD. Chlorophyll-a and salinity were positively correlated with FD, meanwhile FD was inversely correlated to turbidity and SST. The study also observed minor differences in the physico-chemical parameters associated with African penguin foraging grounds, though different dietary preferences were found between the anchovies regurgitated from penguins from the two colonies. Anchovies regurgitated by penguins from Bird Island targeted large sized groups such as Decapods, meanwhile anchovies from the St Croix penguin colony targeted small sized Ostracods and Cirripedia. This study therefore, provides insight on the influence of fluctuations in physico-chemical parameters in shaping zooplankton communities in Algoa Bay. The study also emphasises anchovy dietary plasticity, switching from selective feeding to opportunistic feeding in instances of prey shortages which contributes to a stable African penguin food web in the face of climate change. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: Structurally complex habitats such as seagrass, mangroves, and seaweed are important as nurseries in estuaries and nearshore marine environments. While numerous studies have focussed on structurally complex vegetated habitats in estuaries, few studies have focussed on vegetated nursery habitats (particularly seaweed) in coastal areas and their importance. The main aim of this project is to examine the nature of shallow water vegetated habitat (Zostera capensis seagrass and Plocamium corallorhiza macroalga) usage by juvenile fish in the Algoa Bay shallow water seascape (Swartkops Estuary and Flat Rocks nearshore subtidal reef). This aim was achieved by quantifying and comparing complexity of these two habitat-forming species, and the fish assemblages (relative abundance, richness, size structure and behaviour) across the two habitats. To measure and compare complexity of Z. capensis and P. corallorhiza, canopy height, density and leaf/blade width were sampled. In addition to these structural complexity indices, Fractal D (dimensionless complexity indices) was also quantified using Image software. Zostera capensis (1553.3 Indiv/m2 ) had a slightly higher mean density compared to P. corallorhiza (1303.7 Indiv/m2 ) but the difference was not significant. When sites (within each habitat) were compared, density did not show any significant differences between sites. Canopy height of Z. capensis (56.9 cm) was significantly higher compared to P. corallorhiza (16.6 cm), with no significant differences between sites. On the other hand, P. corallorhiza (0.9 cm) blades were significantly wider than Z. capensis (0.2 cm) leaves. Fractal D values followed the same trend as leaf/blade width with, with P. corallorhiza (1.8) having significantly higher Fractal D values than Z. capensis (1.5). The last two indices also had a positive relationship as Fractal D increased with increasing leaf/blade width. These results show that overall P. corallorhiza is more structurally complex than Z. capensis. Calibrated mini stereo underwater remote video systems (mini stereo-RUVs) were optimised in these two studied habitats to ensure they were suitable to measure and identify juvenile fishes. A pilot optimization study found that a minimum of five deployments and a minimum of 45 minutes filming duration is required to study fish assemblages in these two habitats. For comparison of fish assemblages and assessment of habitat use by fish, mini stereo-RUVs were deployed in both habitats (three sites per habitat) and were left to record for 60 minutes for a v total of five sampling occasions in seagrass and seven sampling occasions in macroalga between 7 September 2020 and 9 April 2021. Collected videos were analysed, with relative abundance (MaxN), richness and fish length extracted. Fish behaviour was also analysed and compared between habitats. Mean fish MaxN was slightly higher in Z. capensis (3.4) than in P. corallorhiza (2.9), although this result was not significant. Species diversity was significantly higher in P. corallorhiza as shown by both richness (Z. capensis = 11 and P. corallorhiza = 18) and the Shannon diversity index (Z. capensis = 1.3 and P. corallorhiza = 1.7). Both habitats were dominated by species from the family Sparidae, with six estuary-associated marine species common between the two habitats. Both Z. capensis and P. corallorhiza were dominated by juvenile fish, with more than 70 % of measured fish being juveniles. Fish length was not significantly different in the two habitats. Juvenile fish assemblages were significantly distinct between the two habitats (ANOSIM). In terms of habitat use, fish behaviour analysis showed that fish use both habitats as nurseries. There was no significant difference in fish behaviour in the two habitats and fish behaviours associated with higher levels of habitat use (slow meandering and feeding) were the most common behaviours in both habitats. Although not significant, feeding behaviour (also associated with a high degree of habitat use) was observed more in macroalga than in the seagrass habitat. Although none of the studied complexity indices could be related to abundance, both leaf/blade width and Fractal Dimension showed a positive relationship with the number of species recorded, while canopy height showed a strong negative relationship with the number of species. Overall, this study shows that Plocamium corallorhiza red macroalga in the shallow marine environment may be as important in shallow marine environments as Zostera capensis seagrass in estuaries as nursery habitats for marine fi , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

Both Z. capensis and P. corallorhiza were dominated by juvenile fish, with more than 70 % of measured fish being juveniles. Fish length was not significantly different in the two habitats. Juvenile fish assemblages were significantly distinct between the two habitats (ANOSIM). In terms of habitat use, fish behaviour analysis showed that fish use both habitats as nurseries. There was no significant difference in fish behaviour in the two habitats and fish behaviours associated with higher levels of habitat use (slow meandering and feeding) were the most common behaviours in both habitats. Although not significant, feeding behaviour (also associated with a high degree of habitat use) was observed more in macroalga than in the seagrass habitat. Although none of the studied complexity indices could be related to abundance, both leaf/blade width and Fractal Dimension showed a positive relationship with the number of species recorded, while canopy height showed a strong negative relationship with the number of species. Overall, this study shows that Plocamium corallorhiza red macroalga in the shallow marine environment may be as important in shallow marine environments as Zostera capensis seagrass in estuaries as nursery habitats for marine fi , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: Solar energy has become an attractive and environmentally mindful method in electrical power generation as it contributes significantly to meeting the high demand for the power needed for socio and economic developments. The rise in deployment of Photovoltaic (PV) facilities with large capacity creates the need for accurate and reliable PV inspection techniques for optimum performance, the longevity of PV modules and quick return on PV investment. The performance of PV modules in the field is often monitored through several inspection methods that require a rapid throughput such as Thermal Infrared (TIR) imaging and current-voltage (I-V) measurements. Unmanned Aerial Vehicle (UAV) based TIR imaging is widely applied in large PV plants since it is cost-effective and is usually conducted in-situ while the plant is operating at irradiance levels above 600 W.m-2 . One of the outcomes of the interpretations of TIR images is an attempt to quantify the energy loss in PV plants associated with the abnormal thermal signatures identified on TIR images. No standard procedure has yet outlined the quantification of energy loss related to TIR images of underperforming modules since the interpretation of TIR images remains a challenge. PV modules operate under dynamic operating conditions which can influence the results and interpretation of thermal and electrical characterisation measurements. Dynamic operation conditions refer to any disorders in the operation of the modules and cells which cause a change in the current and voltage characteristics of the PV source. These dynamic operation conditions include; changesin load conditions, irradiance, soiling and shading levels. The tests were done under steady state conditions. Although measurements are generally done while the operating conditions are as steady as possible, some changes in conditions have a profound effect on thermal and electrical measurements. In this study, these effects and some of the changes in conditions that cause them were studied. , Thesis (PhD) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2022

- Description: Coastal ecosystems provide society with important ecosystem services: climate regulation, biogeochemical nutrient and waste cycling, food security, shoreline protection, tourism, and recreational support. Increased anthropogenic pressure on coastal ecosystems and changing environmental variables ultimately affect the provision of ecosystem services. Mesozooplankton are key trophic species and biological indicators of change within the marine environment and provide sound predictions of ecosystem responses to a changing climate due to their short life cycles and physiology linked to temperature. Algoa Bay has been the subject of extensive research and monitoring and encompasses a marine protected area (Addo Elephant National Park MPA). The Underwater Vision Profiler 5 (UVP5) was utilised with conventional sampling techniques of the PELTER monitoring program (i.e., Bongo nets) to investigate mesozooplankton (200 – 2000 µm) and particle (> 100 µm) dynamics within the dynamic coastal ecosystem of Algoa Bay, located within warmtemperate South Africa, in spring 2020 and summer 2021. This study revealed seasonal shifts in mesozooplankton taxa succession from spring herbivorous/omnivorous, dominated by copepods, to summer omnivorous/carnivorous mesozooplankton, dominated by copepods, Noctiluca sp., Cladocera, doliolids, salps and siphonophores. The mesozooplankton integrated abundance (mean ± standard error) increased from spring to summer, with 101 ± 26 (min. – max.: 18 – 200) x 103 ind m¯ 2 and 422 ± 80 (min. – max.: 37 – 1056) x 103 ind m¯ 2 , respectively. In summer, mesozooplankton composition was affected by the passage of a Natal Pulse, identified from satellite-derived sea level anomaly data. This study also provided the first vertical profiles of copepod distributions and suspended particles in Algoa Bay, with a peak of small particle (< 1 mm ESD) biomass close to the bottom and often, but not systematically, higher copepod abundances above the thermocline. The results presented herein are expected to contribute to the understanding of the coastal pelagic ecosystem in Algoa Bay in response to environmental perturbations , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: Elaborate plumage ornamentation in birds has fascinated scientists since the 1800s. The evolution and persistence of elaborate and costly ornamentation seemed to be in opposition to the theory of natural selection. However, over the years research has revealed the role and functional significance of elaborate plumage ornamentation in sexual selection. Recent studies have shown that the energetic costs associated with moulting into new plumages are higher than maintenance costs, but these costs have not been quantified for species that exhibit elaborate breeding plumage ornamentation for sexual selection. In addition, for these sexually selected ornamental traits (signals) to have evolved and be maintained, there must be some aspect of individual quality that they convey to the receiver. Despite a large body of literature on sexual selection, honest signalling and ornamental plumage in birds, the physiological correlates of honest signalling during sexual selection and the messages these signals convey to the receivers are poorly understood. In this study, I investigated four aspects related to the honesty of the sexual selection signal. These were (i) seasonal variation in standardised resting metabolic rates of breeding and non-breeding birds, (ii) moult phenology, (iii) physiological parameters linked to honest signalling, and (iv) the energetic costs of production and maintenance of elaborate plumage ornamentation using three species from the Euplectes genus as model species. The three species selected, the red-collared widowbird (Euplectes ardens), fan-tailed widowbird (Euplectes axillaris) and the southern red bishop (Euplectes orix) represent a gradient of plumage elaboration and although the receivers of the sexual selection signals are known for these three species, the energetic cost of the signals and the underlying message the signals convey remain unknown. I measured seasonal variation in resting metabolic rate (RMR), body mass (Mb), thermoneutral zone (TNZ) and body temperature (Tb) over the course of two years in the three selected Euplectes species (E. ardens, E. axillaris and E. orix; chapter 2). My results showed no significant effect of season on RMR (except in E. orix females) suggesting that in these species the metabolic costs in summer (associated with breeding season) are comparable to the metabolic costs associated with thermoregulation during winter. Contrary to my prediction that metabolic costs would increase along a gradient of increasing tail length (due to the energetic costs Webb V associated with elaborate plumage ornamentation), I found no significant effect of species. The lack of a significant result indicates that once the initial investment in plumage is complete, other predictor variables play a role (in this case body mass). , Thesis (PhD) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: The therapeutic relationship established between a psychologist and a client is considered one of the main factors determining successful psychotherapy outcomes. While this may be the case, there remain inconsistencies in the literature and debate regarding its influence, especially when contextual factors such as diverse beliefs, may influence the therapeutic relationship. Furthermore, there is a scarcity of information focusing on psychologists’ experiences working within the culturally diverse South African context. This study aimed to better understand, from a psychologist’s perspective, the growth and change promoting factors they feel are influencing successful therapeutic outcomes within the South African context. This was pursued recognising that the diverse belief systems in South Africa, which do not always adhere to biomedical conceptualisations of health and illness, may influence the therapeutic interaction. This study explored the following research question: What are the key factors that promote growth and change in individual psychotherapy within the diverse South African context? Drawing on a qualitative approach, an explorative descriptive research design was chosen as it enabled the researcher to explore the perceptions of the participants on the given topic. The sampling technique that was employed was non-probability purposive sampling and psychologists registered with the Health Professionals Council of South Africa formed part of the sample. In-depth online interviewing was employed as the data collection tool, using online platforms like Microsoft Teams and Zoom. Data were analysed using Braun and Clarke’s thematic analysis guidelines and themes that were identified was reported. , Thesis (MA) -- Faculty of Health Sciences, 2022

- Description: Over the coming decades, Africa is expected to experience disturbing effects due to climate change and increased land cover change due to human influences presenting a significant concern for the future well-being of human and biological systems, the latter being the foundation of ecosystem services supplied to humanity. Therefore, unprecedented transdisciplinary cooperation, coordination, and integration amongst researchers, government, and civil society are necessary to increase the resiliency of these systems. This study aims to provide an outline of the Africa Alive Corridors (AAC) as an essential model for the encouragement of sustainable development through Earth Stewardship science. These aims are accompanied by the quantification and forward modelling for land cover change of the Critical Zone over 10 Great Lake Basins across one of the AAC, the Western Rift Valley Corridor (WRVC), in East Africa between the years 2018 and 2060. This approach provides the foundation for implementing improved regional governance, better encouragement of sustainable development beyond the 2030 United Nations Sustainable Development Goals, and education programs, such as the AAC, that promote socio-ecological resilience through Earth Stewardship Science. The AAC archives a portion of East Africa as the WRVC, a corridor along the western branch of the East African Rift System that highlights twenty heritage nodes, primarily great lakes, mountain ranges, national parks, and biological hotspots. These heritage entities are associated with ca. 12-million-years of evolution and transformation of the East African topography and related African Great Lake (AGL) systems. The thesis defines the study area by delineating AGL basins intersected by the WRVC. Across these basins, land cover change analysis provides a platform for an integrated assessment of the projected health of the corridor region. Existing land cover datasets provide the initial conditions of the study area for 2008 and 2013. Land cover between 2008 and 2013 is cross-tabulated using the Land Cover Module in the Terrset software, followed by the iii delineation of sub-models and driver variable identification. The Multi-Layer Perceptron algorithm provides the transition potentials between tree cover, urban area, cropland, wetland, and open area classes. Change quantification and prediction using Markov Chain analysis are then established for 2018, 2030, and 2060. The model successfully simulated future land cover change and concluded that: (1) proximity to existing human activity, proximity to existing tree cover, and population are the primary drivers of change; (2) the dominant land cover of the ten lake basins for 2018 was cropland at ca. 48%, followed by tree cover at ca. 33%; (3) total anthropogenic change over the coming four decades equates to over ca. 52 000 km2 (5 200 000 ha), and particularly (4) an urban area is expected to increase by >130%. This assessment ultimately provides a platform for regional governance development at the basin scale and Earth Stewardship science in East Africa. These changes require transdisciplinary action from researchers to civil society. The AAC provides the foundation for understanding the dynamics of the systems that support life across broader spatial and temporal resolutions in Africa, highlighting the need for future generations to build socio-ecological resilience to anticipate challenges such as biodiversity loss posed by climate change and excessive land cover change. , Thesis (DSc) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: Estuaries occur at the interface between the terrestrial and marine environment and as such act as the last ‘filtering’ mechanism prior to nutrient pollution entering the adjacent ocean. This study focused on the Swartkops Estuary which is eutrophic and requires the removal of nutrients. The role of phytoplankton as nutrient filters and storage of nutrients by seagrass and salt marsh was investigated. This study found that phytoplankton temporarily took up a large percentage of dissolved inorganic nitrogen (max. 99%) and dissolved silica (max. 76%) and limited amounts of dissolved inorganic phosphorus (max. 18%). The amount of carbon, nitrogen and phosphorus stored by the salt marsh species Spartina maritima and Salicornia tegetaria and the seagrass species Zostera capensis were determined. It was found that the salt marsh grass Spartina maritima stored the most nutrients (149.61 ± 16.59 N g m-2 ; 105.44 ± 13.41 P g m-2 ; 1690.52 ± 168.90 C g m-2 ), while for the salt marsh succulent Salicornia tegetaria less nutrients were stored (27.01 ± 4.17 N g m-2 ; 22.97 ± 3.21 P g m-2 ; 458.66 ± 69.43 C g m-2 ). Zostera capensis also acted as a nutrient store (22.17 ± 6.94 N g m-2 ; 23.75 ± 4.70 P g m-2 ; 221.10 ± 26.74 C g m-2 ). The macrophytes were able to store nutrients for longer periods and thus prevent these nutrients from being exported into the adjacent ocean. On the contrary, phytoplankton uptake was temporary as the nutrients are released once the bloom decays. Without intervention there will be an increase of harmful algal blooms (HABs) and fish kills in the eutrophic Swartkops Estuary. Nutrient input from upstream wastewater treatment works, canals and stormwater run-off must be reduced. Conservation and management of the seagrass and salt marsh habitats is needed to ensure the long-term storage of nutrients , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: Uncertainty surrounds the circumstances of Orphic Hymns’ composition and their intended use. Their author has substituted their own identity for that of the mythological poet and there is no certain reference to the extant collection in any ancient source. They are, in this sense, decontextualised. This study aims to make a contribution to the ongoing debate concerning the hymns’ composition, and the original function they might have served, through an analysis of their poetic and generic contexts. Following a detailed survey of scholarship on the hymns, I reflect first on the collection as a unified text, the constitutive parts of the individual hymns and the methods they employ for addressing, describing and praying to the gods. I then study a select group of stylistic features that the hymns prominently display: their use of phonic effects, including etymological figures, of antithesis and symmetrical patterning, and their extensive repetition of poetic formulae. In each case I discuss the deployment and significance of these poetic elements within the collection and consider the intertextual parallels suggested by their recurrence in Greek literary texts of all periods. This analysis reveals the hymns’ engagement with an overlapping set of poetic traditions, including, most prominently, cultic hymns and oracles, gnomic poetry, the theological discourses of the Presocratic philosophers and, in particular, Orphic poetry in its many forms. It suggests moreover that the hymns engage deeply with the oral strategies of the earliest Greek poets, underscoring the conclusion reached by several recent scholars, that the extant collection is essentially performative and was intended to be recited and heard. I argue that the Orphic Hymns were not a unique text in their employment of the stylistic features studied here, but drew extensively upon earlier hymns composed in Orpheus’ name. I further consider, in the light of this argument, the bearing this study has on the unresolved questions of the hymns’ composition, whether by a single author or many, and the aims of the poet(s) who composed them. , Thesis (PhD) -- Faculty of Humanities, School of Languages and Literature Studies, 2022

- Description: Urbanisation is occurring on a massive scale globally and even more so in the less developed regions of the Global South including sub-Saharan Africa (SSA). Like other developing regions of the world, urbanisation in SSA is not occurring alongside a corresponding growth in urban economies. Resultantly, it is taking place in tandem with the rising scourge of urban poverty, including food insecurity. While urban food insecurity is a clear challenge in SSA, the challenge has however not been met with equal vigour in policy making and implementation circles and even in academia. Problematically, the urban food security literature often focuses on one element of the food system without giving due attention to other components of the system. Resultantly, broader systemic failures and the dynamics related to the different actors across the system-elements are missed. There has thus been recent calls to embrace urban governance in studying urban food systems, which this study does. The thesis examines the urban food system in Bulawayo (in Zimbabwe) with specific reference to urban governance and household food security to understand sociologically the complex multi-dimensional processes, structures, systems, and practices underpinning the urban food system. As a result of the complex nature of food systems, an eclectic analytical framework is employed encompassing Obeng Odoom’s DED framework, Clapp and Fuchs’ framework of power, Gaventa’s power cube and theories of everyday life derived from de Certeau and Lefebvre. Methodologically, the study is informed by a Critical Realism paradigm which accommodates the convergent mixed methods research design employed. The research strategy employed was that of a survey and case study. Key findings reveal that the Bulawayo food system, from production to consumption, is complex and is nested within broader national and international food systems. Although without a direct and explicit mandate on food security, the local authority is at the centre of urban governance processes as it employs a plethora of strategies to influence the nature of the food system. However, the study reveals that the food system is as much a construction from below through the agential activities of the urban poor. , Thesis (PhD) -- Faculty of Humanities, Sociology, 2022

- Description: Unemployment is a long-standing and pressing socio-economic phenomenon that affects, markedly, both developed and developing countries. Although, in one way or another, many people are affected by unemployment, the reviewed literature concurs that youth unemployment is a critical component of the overall unemployment challenge. Indeed, the burden of unemployment is borne, tremendously, by young people, especially those who are Not in Education, Employment, or Training (NEETs). The International Labour Organisation (ILO) has declared youth unemployment a global crisis, with approximately 67,6 million unemployed young people worldwide in 2018. In South Africa, the youth unemployment rate escalated to 56.4 per cent in the second quarter of 2019. This disturbing level of unemployment among young people poses a serious threat—for as long as young people stay unemployed. Indeed, the cost of unemployment is too high, not only does it engender discontent among young people who are floundering in poverty and frustration, but it can also trigger or perpetuate all sorts of social, political, and economic effects. These effects only exacerbate the already intricate and onerous global agenda of tackling unemployment— because they give rise to other socio-economic ills (e.g., crime, among others) that also need to be addressed. Owing to this grave and perpetual challenge of unemployment, exploring and understanding the dynamics of youth unemployment continues to be of paramount importance worldwide. This thesis, in particular, seeks to investigate the factors that impede on the employment of the NEETs category, as it may be extremely difficult for them to enter the labour market— and they may lose hope of entering the labour market later in life, if they are unsuccessful while still young. Unlike graduates or other youth categories (i.e., matriculants) who have better chances in the labour market, some young people (by virtue of being ‘dropouts’, teenage moms/dads, having failed matric, among other reasons), remain the most vulnerable to unemployment. For this reason, the primary aim of this thesis is to examine the ways in which employers’ recruitment strategies advantage or disadvantage young people (NEETs). The secondary aims include: (a) examining how employers' perceptions and attitudes, regarding the NEETs youths, influence their recruitment decisions when it comes to employing young people; and (b) understanding the ways in which government strategies (devised to combat youth unemployment) influence employers’ decisions to recruit the youths’ or not. In essence, this study seeks to explore the demand-side factors in the labour market that can help us understand how employers’ recruitment decisions (or recruitment behaviour) affect the employment prospects of young people in the labour market. The focus on demand-side factors is motivated by Labour Market Segmentation (LMS) theories, which serve as the theoretical framework of this thesis. LMS theories’ significance lies in their opposition to neoclassical economics, that posit the existence of a unified labour market (which operates like all other markets), consisting of buyers and sellers in ‘free’ competition. According to neoclassical theory, the difference between workers’ employment and wages is determined by ‘individual preferences’ and investments in ‘human capital’ (skills, experience, formal education, etc.). By contrast, LMS theorists argue that labour markets are fragmented, and that differences on the demand side imply differences in compensations that are not totally determined by individual workers' human capital. Inspired by the claims of LMS theories, this study elected to explore demand-side factors by applying qualitative research methods and techniques to gather and analyse the data gathered, and to ultimately address the research objectives. In particular, non-probability sampling was used to sample 20 firms from four sectors (manufacturing, retail/hospitality, finance, transportation) in the Johannesburg (CBD) region. The respondents were all asked a series of semi-structured questions in order to yield qualitative results that would help determine the employers’ dispositions towards young people; and about the government’s strategies that address youth unemployment. The aim is to provide an in-depth, nuanced understanding of how the respondents’ dispositions influence the inclusion or exclusion of young people in the employers’ recruitment considerations. The aggregate results of the study generally indicate that—although there are innumerable factors that affect young peoples' employment prospects—young people (without skills and tertiary education or matric) are actually being employed, and are still being considered for employment by the majority of the sampled employers (predominantly from retail/hospitality firms). Only a minority of employers stated, categorically, that they do not employ young people, and do not intend to do so. Conversely, the results also reveal that the the majority of employers often recruit young people for general and entry-level jobs that are often offered on a non-standard employment basis. At face value, the employment of young people (without skills) in the majority of the sampled firms may seem to make a difference—and it probably does, for as long as young people are exposed to the world of work. However, in the 4 grand scheme of things, the kind of employment offered in these firms is also problematic, because it is, basically, transient and unsustainable. As such, the young people that occupy these jobs are most likely to find themselves back in the unemployment queues whenever the ‘part-time’ or ‘temporary’ employment contracts are terminated. These jobs are especially problematic because policies such as the National Development Plan (NDP) 2030—in line with Sustainable Development Goals—aim to reduce poverty by creating sustainable employment. Contrarily, these kinds of jobs make it hard to achieve poverty reduction, because they are inherently unsustainable and barely lift people (especially young people) from unemployment and poverty. Based on these results, it can be asserted that the proliferation of non-standard employment compromises the agenda for decent work, and it delays the already sluggish Sustainable Development goal of creating sustainable employment (among other goals). This, then, reveals that there is still a stark and long-standing need for more radical strategies that will ensure the creation of sustainable jobs—without which the unemployment crisis will be far from over. Moreover, the results further indicate that the reasons why the minority of the sampled employers do not employ young people boil down to the fact that young people usually do not have what employers look for in their potential recruits; or that young people do not have what employers believe will contribute to the growth and productivity of their firms. In essence, employers will never employ any young person (or any jobseeker in general) that will be a liability than an asset in their firms. Over and above, this thesis corroborates many of the explanations—encapsulated in the growing literature—for rising unemployment, as well as the claims that unemployment is highly pronounced among young people. However, the contribution of this thesis is that it further offers a nuanced view to understanding the demand-side factors (as additional determinants) that hinder the employment of young people (especially those who make up the NEETs category). , Thesis (PhD) -- Faculty of Humanities, Sociology, 2022

- Description: This modest research project was situated in a multilingual Early Childhood Development (ECD) setting in the Eastern Cape (EC) province of South Africa. In the context of high levels of poverty and unemployment in the EC, issues such as under-funding, the nature of the training of practitioners, translating the importance of learning through play into practice, difficulties dealing with diverse cultural practices and the use of multiple languages, all impact ECD provision. Research has shown that parental involvement and creating parent-school partnerships can assist children to progress at school. The overall objectives of this project were to explore how a team in an ECD centre might communicate more effectively with parents and how early stimulation practices in home and school might benefit the child’s development. The theoretical framework draws upon Vygotsky’s (1978) socio-cultural historical theory, Bernstein’s (1971) elaborated and restricted language codes and Bourdieu’s (1977) concepts of social reproduction. A research project in the Netherlands Thuis in School, used an education partnership approach (Iliás et al., 2019). They developed a manual that was adapted for our local context by drawing from the theories mentioned, and to counter the dominant approaches where parenting programs have often been offered from a deficit, narrow perspective. Action Research guided the interventionist approach to workshop sessions, to enable mutual capacity-building of parents and practitioners. To ensure informed consent, participants’ first languages were used. High risk factors related to photographs and videos of participating parents and minor children were successfully addressed. Pre- and post-interviews and workshop data were analysed using template analysis, within a constructivist paradigm. Findings include vignettes to introduce the contexts and parents' ideas prior to the sessions. Then, sessions are summarised as action cycles, with key participants' responses. Finally, post-session evaluations highlight the topics the parents found most meaningful; and parents’ and practitioner accounts of changes in practices. This research illustrates ways that educational partnership elements can influence practice and policy, to improve home and school environments for the benefit of children. , Thesis (PhD) -- Faculty of Humanities, Psychology, 2022

- Description: Since the 21st century, digital finance has emerged as a critical enabler and an excellent tool for meeting the UN 2030 Sustainable Development Goals (SDGs) through increasing financial inclusion and poverty reduction. The objective of achieving universal financial access by 2030 has led to recognising that financial inclusion has a significant role in economic growth and poverty eradication. The literature demonstrates that access to finance can affect poverty through access to credit, enabling savings, thereby facilitating intertemporal consumption smoothing. Digital finance is key to unlocking financial inclusion, particularly in developing countries. Building capacity in digital payments is one of the best ways to ensure a faster, better, and more cost-effective way to access financial services. The gender gap in developing countries states that (59% of men were reported to have a bank account in 2014, while 50% of women only had a bank account). Some groups, including women and the rural poor, are financially excluded compared to others. This study applied panel data regression analysis and structural equation modelling to investigate the nature of digital finance, its relationship with poverty and the transmission mechanism from digital finance to poverty in selected Sub-Saharan Countries. The results indicate that remittance is one of the most significant determinants of the use of digital finance in the Sub-Saharan region compared to other determinants of use for digital finance. Regarding the transmission mechanism between digital finance and poverty, the path analysis results suggest that the channel for remittance in the transmission mechanism has a more substantial impact on reducing poverty than savings in the Sub-Saharan region. The study recommends that remittance is essential, but savings are not critical in this digital age. This study contributed to literature by identifying the transmission mechanism between digital finance and poverty. This is beneficial to researchers and policymakers . It provides policy practitioners with a reference point on a model to build upon towards providing solutions to the problem, Sub-Saharan Countries encounter on delivering sustainable and broad-based economic growth. The study concludes by proposing that digital finance, particularly mobile money presents an excellent opportunity to increase access to finance and reduce poverty. , Thesis (PhD) -- Faculty of Management and Commerce, 2022

This study contributed to literature by identifying the transmission mechanism between digital finance and poverty. This is beneficial to researchers and policymakers . It provides policy practitioners with a reference point on a model to build upon towards providing solutions to the problem, Sub-Saharan Countries encounter on delivering sustainable and broad-based economic growth. The study concludes by proposing that digital finance, particularly mobile money presents an excellent opportunity to increase access to finance and reduce poverty. , Thesis (PhD) -- Faculty of Management and Commerce, 2022

- Description: This study investigates the constructions of land expropriation without compensation (LEwC) in the discourses of two mainstream media, Moneyweb and City Press, and two ground-up platforms, Afriforum and the African Farmers’ Association of South Africa (AFASA). It follows the February 2018 adoption by Parliament, of LEwC as a policy to reorder the country’s unequal and racially bifurcated economy. The motivations for, and opposition to the policy locate land as ‘the issue’ in conquest and capitalism. How land is signified therefore, is important to the understandings of ‘restitution’ and/or ‘resolution’. The news platforms selected here are diverse: Moneyweb focuses on investments. City Press concerns itself with politics. Afriforum and AFASA are alternative sphericules linked to ethnically- polarised quotidian concerns with land as a key focus. Discourses are central to how citizens see and construct themselves and one another as subjects. As such, media frames can be connected to justice and inter-‘race’ complexities. This is a study of media influences in cultivating certain meanings and understandings of tenuous and fractious political situations characterised by inequality and interracial enmity. The thesis draws from the Epistemologies of the South as well as Marxism to constitute the locus of its enunciation of colonisation, liberal capitalism, land question, justice, ideology, discourse, and framing. This framework is geared towards emic understanding of interrelated local and global contexts of the land question. Conceptual clarity is key to the development of an emancipatory imagination. Qualitative framing analysis and critical discourse analysis are used in this study to examine a diachronic corpus of 124 articles from the four platforms covering 167-days, from the adoption of the LEwC motion through the initial round of public hearings. The findings suggest a strong influence of the structures of coloniality in discourses across a wide political spectrum. The frames and counter-frames in the four platforms are simultaneously divergent and similar. Some are reactionary and conservative, others are liberal-transformational and even radical-prefigurative. All however, orbit around abyssal, North-centric, liberal capitalist normativity as the centripetal centre. The study proposes rethinking of the land question, a radical exorcism from land discourses, of structures of coloniality of power, knowledge, and being. Their mobilisation, predominance and naturalisation in political communication is anti-transformation and helps keep Black South Africans to this day, under the heavy yoke of an oppressive colonial and Apartheid reality as perpetual economic slaves. , Thesis (PhD) -- Faculty of Humanities, Journalism and Media Studies, 2022

- Description: Clinical governance (CG) is the system through which health authorities are accountable for continuously improving the quality of their services and safeguarding high standards of care by creating an environment in which clinical excellence flourishes. South Africa is one of the countries where CG has not been successfully implemented. This study sought to explore the CG implementation challenges in the Mpumalanga province, South Africa. The study objectives included the seven pillars of CG. The study was a qualitative and exploratory, using purposive sampling technique to select study participants. A total of twenty-two (22) individuals were selected for the study. Semi-structured interviews were used for data collection. Each interview was transcribed verbatim by the researcher. Confidentiality was ensured through the coding of interviewee names. The content analysis technique was used for data analysis, using the study objectives as themes. The study found general lack of understanding of the concept of CG, poor performance of clinical audits, sub-standard clinical performance and effectiveness, poor clinical risk management, poor patient and public involvement in patient care, lack of evidence-based practice and research, inadequate training and development of healthcare workers, and sub-standard health information management across the department. The researcher recommends that the CG policy be prioritised by the Mpumalanga DOH, that systems be put in place to facilitate policy implementation, and that the departmental staff establishments at all levels, prioritise healthcare professionals in key leadership positions. In conclusion, there are numerous challenges that confront the Mpumalanga Department of Health regarding the implementation of clinical governance, requiring urgent attention. , Thesis (PhD) -- Faculty of Health Sciences, 2022

Consumerism, authenticity and African communalism

- Description: Let me state, from the outset, that the issues raised below may be considered from various vantage points – Capitalism, Marxism, etc. However, this thesis is an endeavour to account for the loss of authenticity due to the most salient features of the consumer paradigm, which is the manufactured object, the production line and the proliferation of said objects. True relationships, or shall we say authentic dialogue, is based upon a difference of viewpoints – or epistemic distance – between the interlocutors. This difference of opinion, it may be argued, allows for a cognitive jostling between the subjects involved and represents, as it were, the reciprocal back and forth movement of ideas that betokens actively engaged dialogue. Crucial, then, to true, and by extension authentic, relationships is an epistemic distance steeped in variegated, heterogeneous points of view. For it is in sharing the differences in our points of view or interpretations of the world that we may start a dialogue far removed from each other and then sustain said dialogue in an attempt to reconcile our differences. The continuation of the dialogue, then, depends upon difference. Without the latter difference, the conditions of true dialogue, which is also a marker of authentic relationships, the need for sustained debate is forfeited and the dialogue ceases to serve a purpose – for the subjects involved in the intellectual jostling and exchange of ideas may already anticipate the thoughts of the other. In so anticipating the thoughts of the other, what is brought to the fore is not the ideas of the other, and by extension the other’s existence distinct from mine, but rather my own existence and thoughts. Were I and the other to share a constellation of beliefs, I am left with only that which I already believe in and so only with my own thoughts. The other’s differing opinion is crucial to their appearing to me as an element discreet and distinct from me. For if the other’s being is in essence of the same ilk as mine – and with that I mean if the other’s points of view and adopted systems of praxis mirror mine – we are like trees in a forest. The existence of collective nouns attests to this latter remark; we are prone to see the forest, not the similar trees that constitute it. Now the question arises as to the constitution of the self; what is it that makes up the character and nature of a person and how, if at all, may subjects be said to differ epistemically? According to Sartre, the ego is a transcendent object for consciousness, meaning that it exists out there in the world just like other objects. This is the case because consciousness is essentially empty. Recall Sartre’s famous claim that existence precedes essence, which in turn means that consciousness, or the ego, is filled up inchmeal with contents outside itself. In other words, that with which we are engaged constitutes the contents of consciousness. Repeated exposure to certain objects, or phenomena, brings about the cultivation of states and qualities – these, as it were, constituting the ego in the end. Moreover, these states and qualities, as arisen from repeated exposure to like phenomena, will instil in the subject a certain proclivity for a certain manner of action under specific conditions. As such, having been presented with something disagreeable many times over, a state of repulsion might gain a foothold in my ego regarding the phenomenon in question. This in turn will dictate how I act in the presence of said phenomenon or any other phenomena that include, adumbrationally, some of the qualities of the original phenomenon. As such, then, my actions are reflections of the states that I experience in the presence of certain objects or phenomena and, it may be argued, reflexively represent the world around me as that which constitutes my ego. The facticity of the world, then, has a great bearing upon the manner in which I perceive and engage the world. However, claims Sartre, facticity is but one side of the coin. The world and its meaning are constituted by what Sartre calls brute meaning. This refers to the fact that meaning is a matter of public opinion and does not precede the phenomenon or object itself – the latter being, in essence, but a bare, pliable, monstrous mass of being-in-itself. Due to this occurrence of meaning being man made, we are in a unique position of freedom. We are, he further claims, capable of transcending these brute meanings, enabling us to avail ourselves of the objects or phenomena in question in a bespoke manner. Freedom to choose how we interact with and interpret the world is thus the ontological ground of choice. We have, on the one side, the world in its undifferentiated state – being-in-itself – and on the other the possibility to give this world a specific meaning in accordance with our intentions – being-for-itself. Freedom to choose, so construed, thus ontologically underlies the very fabric of our existence, hence the claim that we are condemned to be free. Choosing whether to continue along the path set out by our original factual condition or to transcend it and make of it something different altogether is thus not a choice at all, but the obligatory condition of the human condition. Once again, this is the case because consciousness, as per Sartre, is empty to start with and can only be filled with the contents of phenomena or objects in accordance with our intentional engagement of them. However, Sartre continues, this freedom of meaning and the fact that brute existents represent nothing more than the convergence of publicly ascribed meaning awaken in the subject a certain nausea – a nausea born of the fact that we, the people, are at every junction in a position where we have to choose the meaning of life. Determinism, thusly, does not exist and we are not only free to choose the meanings of our own lives, but are responsible for what our lives become. This realisation proves to be too much for most to stomach and leads them along a specific path of choice: over-identification with either their factual realities or with the possibility to transcend the latter. Either way, what they aim to achieve with this overidentification is the suppression of the nauseating reality that reality is nought but what we make it to be and we are thus responsible for what it becomes. Sartre calls this bad faith. Pandering to this proclivity towards bad faith, or alternatively, the propensity for overidentification with either side on the facticity/transcendence dichotomy, we find consumerism. The consumer paradigm delineates happiness as an objective ideal, attainable through the acquisition of specific markers of demonstrable happiness. At the same time, it also provides an answer to the nauseating reality that we, humans, are never fully determined beings, but find ourselves vacillating between our factual constraints and our transcendences thereof. It offers us the crystalised means of becoming this or that individual by way of populating our immediate and personal surroundings with signifiers of happiness. Considering, moreover, that a liberalist conception of human being clearly indicates that individuation of each subject is an important aspect of existence, authenticity in terms of rights emerge as a corollary of said individuation. Each individual, so construed, is given the opportunity, the right, to acquire said markers of happiness and individuation. Obtaining these, it may be argued, allows the individual two things: firstly, to quell the nausea that haunts our dualistic lives by concretising it altogether and so doing highlighting the factual side of things; and secondly, to become discreet and individuated subjects, authentic in their beings. However, the authenticity so begotten provides nought but a thin veneer of idiosyncrasy, as the markers of said authenticity are publicly available and so the same for everyone. The problem, thus, of self-individuation is resolved by providing the subject the means of over-identification with their factual realities whilst convincing them, the consumers, that the objects on offer will afford them a degree of happiness and set them apart from their fellow subjects. The unfortunate upshot of this is that subjects all avail themselves of the same set of objects in an attempt to quell the nausea that besets the individual plunged into an undifferentiated existence. We are here at the heart of the matter. Due to the proliferation of like objects throughout the life-world, a specific system of praxis is implied. So as to navigate the life-world and utilise the similar objects that populate it, consumers are driven towards shared ideologies and courses of action. Moreover, their intentions also converge, as they all seek to establish a web of objects around them that would bespeak their individuation and happiness. Where the life-world has become such a homogeneous landscape, it may be argued, in line with Sartrean thought, that the contents of consciousness would also be similar for all. And where the contents of consciousness is similar for all, we may argue that reasoning would be similar for all. It is at this point that dialogue breaks down, for there is nothing epistemically to separate interlocutors and therefore no differences of opinion to sustain true dialogue. If, as it was reasoned some pages prior, it is the case that sustained dialogue provides the predicate upon which authentic relationships are to be based, the collapse of this epistemic distance between consumers must then also lead to a collapse of authentic relationships. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2022
