- Description: Property development is a sector which provides economic benefits to many countries worldwide. Such economic benefits are employment provision and GDP contribution to the economy. Interestingly, financial feasibility is one of the tools that can be used to ensure property development projects’ success. It has been therefore recognised that some of the property development entrepreneurs lack financial feasibility know-how which could position their property development businesses into a competitive edge and sustainability in this continuous fluctuating property market. Hence, the aim of this study was to examine the key factors and variable that drive financial feasibility in property development and generate a financial feasibility model which can be used by property development entrepreneurs to analyse the financial feasibility of property development projects. Based on the aim of this study, an extended review of the literature relating to property business, property development, demand planning and risk management within the built environment discipline was conducted in identifying factors affecting the perceived success of financial feasibility for property development projects internationally. The research reviewed literature in the property development industry by identifying the variables for profitability, outside advice, trend analysis and real estate strategies. The research methodology approach that was used for this study, a qualitative explanatory multi-case study where embedded unit of analysis and valuable insight was provided for the success of financial feasibility in property development internationally. Semistructured interviews were conducted with various industry experts as indicated below: • Project Manager at Property Company; • Project Manager at developer; • Development Manager; • Owner of Property Group; • Part time lecturer at NMU Built Environment; • Development consulting company CEO; vi • Trustgro Developments (Pty) Ltd: Managing Director; • Tswaranang Consulting – Managing Director; • Capelo Development Company (Property Development) Director; and • NMBM - Senior Director: Land Planning and Management. The interview questions and primary and secondary propositions were defined together with the validity and reliability of the research. The purpose of the qualitative research was to unravel key factors that determine the perceived success of international financial feasibility of property development projects. Replication logic was used to generalise the results and the findings of this research effort suggested that the following variables emerging from qualitative themes, positively influences the perceived success of the financial feasibility in property development projects: profitability, risk management, outside advice, trend analysis, property cycles and demand planning. The implication arising from this study is that the perceived success of international financial feasibility in property development projects has the following positive influencing factors: profitability, risk management, outside (specialist) advice, trends analysis, property cycles and demand planning which must be considered by property developers and investors to ensure the success of their property development interventions. The curriculum of property development and real estate management practice should equally take into account the afore-mentioned factors. , Thesis (MA) -- Faculty of Engineering, the Built Environment, and Technology, 2022

- Description: One of the major developmental crises an adolescent must overcome before becoming an adult is identity formation. Many studies focused on how the family influences the identity formation of adolescents, but little emphasis has been made specifically on how the absence of a father impacts the adolescent’s development of identity. This study aims to conduct a systematic review to examine the impact of absent fatherhood on the identity formation of adolescents. Several studies, from the year 2010 to date, have explored the impact of father absence on the identity formation of adolescents. The majority of studies conducted have been mostly quantitative and failed to explore the experiences of adolescents raised in absent-father households during this crucial stage of development. This study sought to add to the body of knowledge and bridge that gap by exploring the possible (negative or positive) impact of absent fatherhood in the identity-formation period of adolescents. This was a systematic review study that included a qualitative research design, whereby published literature and studies were identified through searching electronic databases. To synthesize and analyse the data, thematic analysis was used. This study’s exploration discovered that absent fatherhood can be experienced both positively and negatively by adolescents. Positively, it was found that a sense of independency developed in the adolescent and strengthens family relations and unity, with extended family members or external role models becoming more involved in the upbringing of the adolescent. Significantly, on the negative side, adolescents developed anger and resentment towards their absent fathers, questioning their absence and the individual’s sense of who they are and where they belong. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2022

- Description: Monetary policy plays a significant role in countries economic development. The variability in inflation in the SADC region provides room to question the Effectiveness of the transmission of monetary policy as these countries experience inflation in different ways. The study analyses the effectiveness of monetary policy transmission mechanism on the selected 5 SADC countries, South Africa, Botswana, Mauritius, Tanzania, and Zambia. The selection of the countries was mainly based on data availability. To answer the study hypothesis, the study used secondary data from different data sources, employing the Vector Autoregression Regression. The different channels analysed include the exchange rate, interest rates as well as credit channel to measure monetary policy tools. The main variables are, Gross Domestic Product (GDP), Consumer Price Index (CPI)cpi and money supply. Panel unit root was tested to test the stationarity of the variables and the appropriate lag length was determined. Panel VAR model was estimated where the focus was mainly on variance decomposition and impulse response. Then lastly the stability of the model was tested using diagnostic test. The results revealed that interest rates channel and exchange rate channel have a more significant effect in explaining the transmission of macroeconomic shock to the rest of the economy through gpd and cpi. While the credit channel mostly transmits to the rest of the economy through money supply and cpi, its effects from GDP are rather insignificant. It is also noted that interest rates serve as the dominant channel in transmitting monetary policy shocks to the rest of the economy. When central banks decrease prime lending rates for commercial banks, this is passed to consumers making it less expensive to borrow. In the long run, attracts foreign investors which harms the domestic currency. The author has noted that future research could focus on how asset price channel affects the economy. , Thesis (MCom) -- Faculty of Management and Commerce, 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: The discussion on the viability of the Southern African Customs Union (SACU) as a monetary union has been ongoing for years. SACU is the oldest Customs Union in history, formed in 1910. Employing the Optimum Currency Areas (OCA) theory, the study examined SACU’s readiness for a single currency. There are several technical requirements needed to form an OCA, however, one of the most vital of these with regards to a country’s suitability to enter a currency union is Business Cycle Synchronization. Therefore, SACU’s readiness was tested by establishing Business Cycle synchronization between the 5 member states. Although Business Cycles Synchronization have not been proven, SACU countries have moved towards a complete monetary union because of increasing macroeconomic convergence. Our study using Wavelet analysis sets out to establish if there is a synchronization of Business cycles with SACU members. Cyclical components were isolated, from the real GDP growth rate of each country from 1981 to 2020, using the Hodrick-Prescott filter (HP), Band-Pass filter (BP), and the Christiano-Fitzgerald Filter (CF). In the 2 by 2 analysis, our wavelet coherence showed that SACU countries are synchronized with each other, while South Africa displayed its dominance in the union by showing significant synchronization with all the members of the union both in the short and long run. The Vector wavelet analysis results concluded that, as a group, SACU shows much higher degrees of synchronization. The group synchronization is statistically significant throughout the period of study. Furthermore, there is an indication of consistent synchronization, in the long and short run. Overall, the results of our study conclude that there is synchronization in the SACU countries. Therefore, SACU counties can form an OCA as they meet the desirably requirements. , Thesis (MCom) -- Faculty of Business and Economic Sciences, 2022

- Description: Graduates expect to find employment after completing their tertiary qualifications, but they often face various challenges in finding employment. These challenges may be due to a variety of factors such as the type of qualification, structural changes in the economy, lack of experience, or the lack of relevant social networks. This has the potential to affect a graduate’s psychological well-being. The current study explored the psychological impact of unemployment in 100 unemployed graduates between 21 and 35 years of age in Pietermaritzburg. The study was quantitative and used two questionnaires, the GHQ-12 and a self-designed questionnaire, to collect data. Purposive sampling was used to obtain research participants. The Excel spreadsheet and a statistical software package called JASP (2020, version 0.12) was used to analyse data. The findings revealed that unemployment had a negative impact on the participants’ psychological well-being. Participants experienced feelings of high anxiety and depression, and felt stigmatised. Participants also felt shame and experienced lower self-esteem. Unemployment had a financial impact on participants, including financial dependency on family and friends. Some participants blamed themselves, the government system, and the education system for their unemployment. Participants reported to have a positive attitude towards employment, including remaining optimistic about their chances of finding employment. Participants used adaptive coping mechanisms, such as keeping a positive attitude, and maladaptive coping mechanisms, such as hiding their feelings. Further research needs to focus on psychological services that could assist unemployed graduates to find employment through building and maintaining their self-esteem and confidence which are key factors when initially seeking and obtaining work. Unemployment and its impact on psychological well-being has been shown to be to be a complex subject that requires intervention from different parties such as employers and health-care workers, as well as the education system.

- Description: Background: Globally, literature has shown that rugby players struggle to return to the same level of performance post anterior cruciate ligament (ACL) reconstruction. This phenomenon is further exacerbated amongst South African Rugby players, compounded by the ranking of the national team amongst the top ten rugby teams worldwide. Paired with the psychosocial aspect of return to play, the physical and physiological competence of the knee joint is of pivotal importance. Purpose: To compare relative dynamic stability scores paired with electromyography (EMG) scores between the injured and uninjured legs, thereby enabling an explorative, descriptive report on dynamic proprioceptive abilities post ACL reconstruction (ACLR). The study findings therefore aim to inform rehabilitative practice in a rugby player who underwent ACLR. Study Design: A quantitative, explorative and descriptive design was used, with a purposive sampling strategy. Methods: Biographical and anthropometrical data was measured upon inception. Muscular activation was measured using electromyography (EMG) placements on quadriceps muscles which included the vastus medialis obliques (VMO), and vastus lateralis (VL). Dynamic proprioception was measured using the star excursion balance test (SEBT) and normalised to leg length. A neuromuscular fatigue protocol was used to measure the impact of neuromuscular fatigue on dynamic stability, and muscle activation between the injured and uninjured lower limbs. Results: A sample of 15 participants from the South Western Districts (SWD) rugby team, fitting the inclusion criteria, were included in the study. The average age was 27±2.7 years. The results indicated that fatigue did not significantly affect the SEBT scores between the injured and uninjured lower limbs. However, the VMO muscle activation showed a statistically significant difference in muscle firing in a pre-fatigue state. This difference was evident in two of the eight directions namely anteromedial direction (p = 0.041), and in the lateral direction (p = 0.047). Furthermore, these result differences were favoured in the uninjured limb. No significant differences between the injured and uninjured lower limbs were found in respect to VMO and VL muscle activation, in a fatigued state. vi Conclusion: Practically translated, the study results showed that the injured lower limb, showed no significant differences in dynamic stability during both the non-fatigued and the fatigued SEBT. Therefore, the finding of this study is a steppingstone towards informing return to play criteria for adequate dynamic knee stability and proprioception. It should be noted that further research is necessary to refine return to play criteria and thereby decrease the risk for re-injury.

No significant differences between the injured and uninjured lower limbs were found in respect to VMO and VL muscle activation, in a fatigued state. vi Conclusion: Practically translated, the study results showed that the injured lower limb, showed no significant differences in dynamic stability during both the non-fatigued and the fatigued SEBT. Therefore, the finding of this study is a steppingstone towards informing return to play criteria for adequate dynamic knee stability and proprioception. It should be noted that further research is necessary to refine return to play criteria and thereby decrease the risk for re-injury.

- 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: Breast cancer is the most prevalent cancer in women and triple negative breast cancer (TNBC) is one of the most aggressive breast cancer subtypes. Current breast cancer therapies are associated with several side effects and less effective treatment. Therefore, the development of new approaches to improve cancer treatment are needed. The use of gold nanoparticles (AuNPs) for anti-cancer effects is one of the most promising research areas in the field of nanotechnology, because nanoparticles are readily functionalized and can passively accumulate at the tumor site without affecting healthy tissues. The green synthesis of AuNPs is an eco-friendly, costeffective, fast, and non-toxic method that is associated with fewer side effects.The aim of this study was to evaluate the cytotoxicity and apoptotic activity exhibted by Vernonia amygdalina gold nanoparticles (VA-AuNPs) in triple negative breast cancer cell lines. The aqueous extract of Vernonia amygdalina was used to reduce gold salts to form VA-AuNPs. The VA-AuNPs were synthesised at a temperature of 100 °C and pH 7. The synthesised green AuNPs were charactised using ultraviolet-visible spectroscopy, dynamic light scattering, and high resolution transmission electron microscopy. Spherical VA-AuNPs were succesfully synthesized with average size of 17.11 ± 2.82 nm and a zeta potential of -36.55 ± 1.15 mV. The MTT assay revealed that VA-AuNPs significantly reduced (p cell viability for both mouse (E0771) and human (MDA-MB231) TNBC cell lines in a dose-dependent manner. The PrestoBlue assay showed a consistent decrease in cell numbers over time, suggesting either a decrease in proliferation or increase in apoptosis. The apoptotic effects of VAAuNPs were assessed using the CaspGLOW Fluorescein active caspase-8 staining kit. It indicated that caspase 8 was activated when cells were treated with VA-AuNPs. E0771 and MDA-MB231 cells were compared when treated with VA-AuNP and a similar trend was established. The HRTEM image showed VA-AuNPs in an vesiclelike structure inside the cell. It can be concluded that the VA-AuNPs showed anticancer activities against TNBC cells. Caspase 8 is activated by VA-AuNPs, confirming the induction of apoptosis, but does not exclude the activation of the intrinsic apoptotic pathway or inhibition of proliferation activity. E0771 and MDA-MB231 cells showed similar cytotoxic activity and thus expected that the mechanism of action in these cell lines should also be similar. Future in vivo research, using the mouse model inoculated with E0771 TNBC cells, should be justified and comparable with human TNBC cells. , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2022

- Description: SA has a high number of reported cases of multidrug-resistant tuberculosis (MDR-TB). Bedaquiline is a newly approved active ingredient of an anti-tuberculosis drug with high potency against MDR-TB. The limited access to this life-saving medicine to many people in the world has driven a great deal of research effort by the scientific community to find new, better and more practical approaches to this drug. However, many of the reported synthetic procedures suffer from long reaction times, which in turn require many hours of effort by the chemists conducting the reactions. This has prompted us to investigate an efficient process towards the synthesis to produce the key intermediates of bedaquiline using continuous flow technology. Additionally, since there is not much literature on continuous flow synthesis of bedaquiline, this research revealed interesting continuous flow processes towards the drug. Chapter 1: In order to provide insight, the first chapter of this dissertation presents a comprehensive background and literature review on tuberculosis; its pathogenesis, impact, medicines available for the treatment as well as the drug classes with novel mode of action and new chemical entities. Furthermore, bedaquiline is discussed in detail with the various synthetic protocols of the drug. An introduction to continuous flow chemistry is discussed, along with an outline of its advantages and disadvantages. Chapter 2: The second chapter encompasses the experimental procedures utilized for both batch and continuous flow syntheses. The three key intermediates of bedaquiline were synthesized in batch synthesis and these compounds were characterized using 1H-NMR, 13C-NMR and FT-IR spectroscopy. Subsequently, the continuous flow synthesis protocols for the preparations of these intermediates and their optimization are outlined. Chapter 3: The results are explained in this chapter with detailed discussions of the batch synthesis and the continuous flow optimization of each step within the scope of this research. The investigation started with the batch preparation of the primary intermediate, N-(4-bromophenyl)-3-phenylpropanamide via an amidation reaction between 3-phenylpropanoyl chloride and p-bromoaniline. The primary intermediate then undergoes a subsequent formylation and cyclization via a Vilsmeier–Haack reaction to yield 3-benzyl-6-bromo-2-chloroquinoline. The chloroquinoline ii intermediate undergoes a methoxylation reaction to form 3-benzyl-6-bromo-2- methoxyquinoline. Subsequently, the batch protocol was transferred into continuous flow systems, optimized by varying reaction parameters within the synthesis route to achieve the as much yield as possible. The optimization studies showed an improvement in conversions in the various steps with shorter reaction times. The first step was optimized in a 0.2ml microreactor and because of the enhanced safety of flow chemistry, this exothermic amidation reaction was optimised at elevated temperatures to afford the primary intermediate at a 100% conversion within a residence time of 5 seconds using DMF as a solvent with DIPEA as a base. Next, the Vilsmier-Haack cyclization and chlorination was optimised in flow to afford the 2-chloroquinoline intermediate. The ability to use a back pressure regulator allowed for investigation of the effect of high temperature on the reaction and the 2- chloroquinoline intermediate was obtained at 78% conversion in a residence time of 30 min at 150 ⁰C using acetonitrile as a solvent. Subsequently, the optimization of the third step in flow to afford the central core intermediate of bedaquiline, 3-benzyl-6-bromo-2-methoxyquinoline, achieved 100% conversion in DMSO/MeOH solvent system at a residence time of 5 min. The effect of temperature, molar equivalence and solvent on reaction conversions could be observed in these steps. The results obtained from this study clearly demonstrated the successful establishment of an efficient flow chemistry protocol that can be used to successfully synthesize all intermediates within the scope of this research. , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2022

- Description: Over the last decade, a bold move has been made by researchers to shift focus on improving and establishing accurate and reliable measures of economic activity across the globe. With an everchanging global economic landscape, unreliable GDP statistics and the lack thereof have held a nascent impact on formulating appropriate stabilization policies. This, in turn, have affected the affairs of nations, especially low income and developing ones. In an attempt to find alternative ways to measure economic activity, night time lights data have emerged in numerous empirical studies as a novel way of attempting to measure economic growth and development. Various studies have found this to be useful for countries that do not have statistical capabilities such as poor nations, while other studies have put forward arguments in favour of a possible non-linear relationship between GDP and night time lights data. Against this background, this study implores night time lights data extensively to establish whether it can serve as a possible measure of GDP in Sub-Saharan Africa between 1992 and 2012. Based on the results obtained from testing for a positive correlation between GDP and night time lights data in Sub-Saharan Africa, the study further aim to use night time lights data as a measure of GDP in the regressions against proxies of well-being, urbanization, and environmental degradation. The significance of the study relates to the fact that the estimation accuracy of GDP is positively influenced by spatial and radiation resolution of night time lights data. In addition, by taking a country-specific approach using more advanced econometric estimation techniques, this study improves on the empirical literature pertaining to African countries. All facets of pooled ordinary least squares (POLS), the pooled mean group estimators, as well as the wavelet coherence estimation techniques were the three approaches used to investigated correlations between night time lights data and economic activity. Overall findings indicate little evidence that night time lights data derived from the DMSP-OLS archive can serve as a strong measure of GDP in regressions across the Sub-Saharan African region. Recommendations and avenues for future research are outlined at the end of the study. , Thesis (PhD) -- Faculty of Business and Economics Science, School of Applied Accounting, 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

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

- Description: Cost control in the South African public health sector has become a major concern due to the amount of money that the government loses every financial year. If costs in the South African public health sector are not kept under control there might be catastrophic consequences. Regardless of the challenges in controlling costs in the health sector, scant studies have explored the cost control phenomenon, which is seen as a scientific management technique to control and lessen the cost of conducting business. Keeping costs under control in the health sector became particularly important during the COVID-19 pandemic when the budgetary burden on the health sector worsened. This study aimed to identify challenges to cost control in the Eastern Cape Department of Health and come up with recommendations on how the challenges can be addressed. The study followed a qualitative research approach and an interview schedule with open-ended questions was prepared to answer the research questions that were formulated. The research sample consisted of 13 employees of the Eastern Cape Department of Health with work experience ranging between 11 and 15 years to ensure credible data. The study’s findings revealed that the participants who were interviewed had an idea of the cost control concept; that cost containment committees help reduce costs by monitoring and evaluating expenditure to ensure that the funds that are spent result in added value; that cost control is an important concept in the health sector, as it ensures that expenditure is reduced and that the influx of undocumented immigrants exerts unexpected pressure on the health sector as these people are generally not taken into account when the budget is drawn up. Findings from the study could assist in formulating strategies that can be employed to improve cost control in the health sector, for example, immunisation and educating employees and management about cost control measures and how they can be implemented. , Thesis (MBA) -- Faculty of Business and Economic Science, 2022

- Description: Today, a number of disciplines across the social sciences have begun to pay attention to gender; however, gender studies suggest a degree of empowerment for feminist knowledge and not enough recognition that men, too, are gendered beings. As the gender spectrum acknowledges inclusions across options of the gendered form, a greater understanding of gender experiences is required to assist in the development of solutions and systemic changes in society. The study uses qualitative research methods such as one on one interviews to open conversations with self- identified gay men, leading to a deeper understanding of masculinities and what it means to be a man within contemporary society. The proposition made in this study on the notions of men and masculinities is that they can be seen as a gender puzzle, or a gendered Rubik’s Cube, which when considered in this way contribute towards a better understanding of humanity. A Rubik’s Cube approach could facilitate the proposed changes of a deeper analysis of men and masculinities. This study fundamentally explores the lived experiences of the participants and how these experiences come alive in relation to masculinities in contemporary society and offers recommendations to facility positive change, such as about the understanding, the role, the process, and the purpose of ‘coming out’ as a gendered form of both expression and self-identity. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2022

- Description: In the South African context, the demand for network connectivity as a basic human right has increased (BusinessTech, 2022). In urban areas with functioning telecommunication network coverage the demand has heightened while there is also significant growth in the demand for network connectivity in remote and rural areas such as villages, small towns, as well as peri-urban areas. The rising demand for network coverage as well as the initiative to recognise network coverage as a basic human right prompted the South African government to put a plan in place for the supply of free internet data to low-income households (BusinessTech, 2022). The main aim of the study was to investigate the need for the construction, upgrade, and installation of telecommunications tower mast infrastructure in areas of the Eastern Cape that have a great need for the services. This was achieved by analysing the various requirements and challenges that technical teams are faced with within the telecommunications sector, and in doing so, the study aimed to understand the ways in which the infrastructure gap among different socio-economic groups in the country may be closed. The findings of the study suggest that, although there is a demand for construction of new tower mast infrastructure, there is a greater need for improving the existing infrastructure. It is recommended that this may be done through initiatives aimed at protecting the existing infrastructure against vandals, ensuring rural communities are assisted in the use of funds obtained from the leasing of land, there are more stringent consequence management processes in place for individuals who mismanage resources obtained from tower mast infrastructure, and that infrastructure sharing and the upgrade of existing infrastructure is the best alternative in increasing network coverage for rural areas. , Thesis (MA) -- Faculty of Engineering, the Built Environment, and Technology, 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: Many businesses are becoming more aware of the importance of employee well-being and health. There has been increasing public interest in merging wellness activities with an employer's obligations. This shift toward healthy workplaces and empowered individuals reflects a correlation between organisational well-being and pleasant psychological states. As a result, several programmes such as Employee Assistance Programmes (EAP) and Employee Wellness Programmes were established to address workplace wellness issues. Employee Wellness Programmes are intervention programmes targeted at improving the well-being of employees. The epidemic has underlined what was already obvious prior to the virus's emergence: that firms no longer require hero leaders. Today's most effective leadership at all levels is not about technical knowledge or knowing all the answers. It is about being human, displaying vulnerability, connecting with others, while being able to unlock their potential, in addition to communicating a clear direction. This study was conducted to determine the preparedness of leaders to manage employee wellness at lower, middle and upper management levels at Continental Tyres South Africa (SA). For this study, primary data was collected by means of semistructured interviews. Qualitative data was collected by conducting interviews with employees from lower, middle and upper management. Face-to-face interviews, using open ended questions, were used to assess managers’ preparedness to address staff wellbeing. Employee wellbeing is a vital component for any organisation's performance in all facets of business operations, according to the findings. Fundamental training is required to ensure leaders are prepared to deal with employee wellness issues. The absence of this training is a major contributor to inadequate policies, procedures, and cultures that should promote employee wellness in an organisation. The lack of training that would contribute to leader preparedness in managing employee wellness has been apparent in this study. Another emerging conclusion that was highlighted in this study is the lack of prioritisation of wellness initiatives and awareness of resources available to employees. This conclusion is a key factor in understanding why there is such a iii deficiency in fundamental training for leaders within the organisation. The lack of prioritisation could have a direct impact on the lack of training offered to leaders in the organisation. , Thesis (MBA) -- Faculty of Business and Economic Science, 2022

- Description: This research study explores indigenous sorghum food management practices as a pathway towards sustainable food systems. The level of hunger is ever-increasing, and so is the global population. Regions less industrialized and developed suffer the most as they host growing populations and most of the worlds undernourished. Further intensified in this problem are a culling and unforgiving food systems run by a few conglomerates and a knowledge system driven by a histography of ‘othering’ even in its knowledge creation process. Although there exist institutions such as the United Nations Food and Agricultural programs, these remain relegated to policy and intergovernmental level, in the process, not being mindful of the real food issues faced at the grassroots level. This research study centralizes indigenous food practices to make sense of how rural and indigenous livelihoods such as those located in the Moshana village thrive and survive in a monopolized and urban-centred food climate like South Africa. By interviewing 12 participants, living, and taking part in the Moshana village food systems and employing stringent face-to-face semi-structured interviews, we present an indigenous food system as experienced and shared by Moshana Village Community members. The findings present an array of indigenous and food management practices, perspectives through an African ecological philosophical view. Conceptually inspired by the works of Vandana Shiva and many global south thinkers on seeds, grains and sustainable indigenous food systems, this study hopes to reinsert back the centrality of food in the growing field of African Sociology. The findings clearly show that elderly women are preserving the Sorghum knowledge and preservation processes. These practices have assisted the Moshana Village community members to cope with food shortages and lockdown restrictions during the strict COVID-19 lockdown in South Africa. The study concludes with clear need for the archiving and intergenerational communication of food management within the rural communities. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2022

- Description: This study was concerned with exploring and describing a solution to optimise access to development finance for SMMEs in South Africa. SMMEs and entrepreneurs have long been identified as key drivers of economic development, job creation, and poverty elevation. In response to this and, in an effort to support SMMEs, the South African Government has established a number of development finance institutions with a specific mandate to support SMMEs by providing them with both financial and non-financial support. However, this much-needed support is constrained by several independent factors. The objective of the study was to identify information technologies that are currently available in the financial sector and explore how they can be integrated into development finance institutions (DFIs) and SMMEs to streamline their access to finance. The research started with a structured literature review, followed by a qualitative case study research design, and utilised ten (10) embedded units of analysis. These respondents consisted of industry experts in the field of SMME finance, senior employees within the sampled developmental finance institutions, as well as experts in the financial technology sector. The findings of the study, through the views of the sampled industry experts and relevant literature reviewed, revealed that it can be collectively summarised that there is a need for information technology such as Fintech in the development finance and SMME sector in South Africa. It is evident that a need exists to streamline the current application process to access development finance for SMMEs looking for finance. There is a significant misalignment between the current demand for development finance by SMMEs and the magnitude of finance supplied by DFIs to SMMEs looking for finance. The study then concluded with practical recommendations for the streamlining of development finance by using relevant Fin tech solutions. , Thesis (MBA) -- Faculty of Business and Economic Science, 2022

Midwives ought to show respect, kindness and continuous psychosocial support during childbirth to women, who have the right to receive the highest possible standard of care and to be treated with dignity and respect before, during and after childbirth. However, an increasing number of complaints of the uncaring behaviour of midwives towards labouring women has indicated a problem that has not been fully researched. Therefore, the study aimed to identify and describe caring behaviours in the context of midwives in Botswana; determine the inhibiting factors of caring behaviours of midwives during childbirth; and make recommendations to midwives and unit managers based on Swanson’s (1991) Theory of Caring, which might lead to the optimisation of caring behaviour in Botswana midwives. A quantitative, descriptive research design was followed to answer the research questions, and a structured, self-administered questionnaire, which had been developed by the researcher based on the literature review, was used to capture data. A purposive sampling method was used to select 200 respondents working in maternity units in the Kgatleng and Greater Gaborone regional health districts in Botswana. The questionnaire was evaluated for reliability and validity to ensure that it consistently and accurately measured what it was intended to measure. A pilot study was conducted with 10 midwives who met the criteria for participation in the study to pre-test the feasibility of the questionnaire in preparation for the main study. In addition, ethical principles, such as informed consent, respect for persons, anonymity, confidentiality and beneficence were followed throughout the study. The questionnaire consisted of questions and statements. It was divided into three sections. Section A: Demographic attributes; Section B: Identification and description of the caring behaviour of midwives: Section C: Determination of the inhibiting factors of caring behaviours in midwifery. The data provided by the respondent’s answers to the questionnaires were statistically analysed using the Statistical Package for Social Science (SPSS®): Version 27 with the assistance of a statistician, thereby generating descriptive and inferential statistics. v The results of the data analysis revealed that most of the respondents provided positive responses, thereby indicating caring behaviour in midwifery practice. However, several factors that inhibit the caring behaviour of midwives were identified, such as a shortage of staff, work overload, a poor working environment, the inconsistent selection of staff for professional development, a lack of equipment, the young age of some of the woman (less than 15 years), the parity of the woman (more than one child) and the negative behaviour of many of the women. Therefore, recommendations for midwives and unit managers based on the five processes of Swanson’s (1991) Theory of Caring were made that could be used to optimise midwifery care in Botswana. , Thesis (MNurs)-- Faculty of Faculty of Health Sciences, 2022
