- Description: This study sought to explore the effectiveness of using the strategy instructions approach (SIA) to teaching reading comprehension. This research was necessitated by the fact that most South African children do not perform well when it comes to reading comprehension. Many researchers from the literature, such as Rule (2017) and Pretorius and Klapwijk (2016), revealed that most language teachers, especially English First Additional Language teachers, do not have adequate skills to teach learners reading comprehension effectively. Even though in the Curriculum and Assessment Policy Statement (CAPS) document, which should serve as the ultimate guide for teaching English, some strategies are clearly spelt out to be used to teach reading comprehension, the teachers do not use them. This study used the SIA, which contains some of those strategies in the CAPS documents to teach the reading comprehension to grade 8 learners in Elliotdale CMC in the Amathole East District of the Eastern Cape of the Republic of South Africa. The study also sought to find out if SIA could develop positive attitudes and autonomy in the learners towards reading comprehension. The constructivist theory of learning and the schema theory of teaching reading comprehension were the two theories that underpinned the study. A control group and an experimental group (sampled from three schools) were used to determine the effectiveness of SIA when compared to the traditional teaching approaches used by teachers to teach reading comprehension. The study revealed that the use of SIA to teach reading comprehension developed positive attitudes and autonomy in reading comprehension. Finally, SIA has become effective to increase the performance of learners in reading comprehension. The study recommends that teachers should be trained in the higher institutions to use SIA to teach reading comprehension and teachers in the field should be developed to learn how to use the strategies to teach reading comprehension. In addition, more hours should be allocated on the school timetables for teaching reading comprehension. Finally, more reading materials, together with more reading activities, should be given to learners in the schools, especially schools in the rural areas. , Thesis (Masters) -- Faculty of Education, 2023

- Description: Classroom management strategies in teaching and learning are still a challenge in most high schools. The study investigates how classroom management strategies can be enhanced towards effective teaching and learning in Gauteng Province, South Africa. The research is lenses within an interpretive paradigm and was conducted using a qualitative approach, and a case study research design was employed. The study employed purposive sampling to select relevant participants from high schools. The participants consisted of twelve teachers from three chosen schools in Gauteng Province in the Ekurhuleni North District. Each school had four teachers as participants, making a total of twelve participants. Semi-structured interviews were conducted to elicit information from the participants. Content analysis was applied to analyze and evaluate the data from the conducted semi-structured interviews. The findings were as follows: teachers' ineffectiveness affects classroom management, especially when there is a lack of planning, poor time management, and poor relationship between the learners and teachers. It is suggested that teachers need to take charge of knowing what roles to play, such as being the controller, assessor, and organizer in the classroom setting. Recommendations were made to address the implementation of classroom management strategies in the classroom, whereby active teaching and learning need to take place in the schools. Therefore, it is possible for teachers to successfully implement classroom management by always being flexible, such as being able to read the classroom environment, implementing necessary discipline measures without attracting attention to themselves or interrupting the class session, and prioritizing professionalism always. , Thesis (Masters) -- Faculty of Education, 2023

- Description: Health plays a critical role in economic development, as it directly affects productivity and ultimately leads to higher per capita income. Within the Southern African Development Community (SADC) countries, health capital has immense significance for labour productivity, serving as a catalyst for growth. This study investigated the relationship between health capital and labour productivity in selected SADC countries from 2000 to 2020, with the chosen period primarily based on data availability and coverage for the selected countries during this timeframe. To accomplish this, the study employed the panel autoregressive distributed lag (ARDL) models and techniques, which leverage the advantages of panel data and ARDL models, enabling the analysis of both short-run and long-run relationships, providing a comprehensive understanding of the dynamics between variables over time. The data for the study period was obtained from a single reliable source, The Global Economy, ensuring credibility. The primary finding from the pooled mean group (PMG) estimator indicates a positive and significant relationship between health capital and labour productivity in the short run, suggesting that investments in healthcare can boost productivity. However, contrary to the expected theory and prior assumptions, the long-run findings reveal a negative and significant relationship. This discrepancy highlights the complexity of the health-productivity relationship and necessitates further investigation to comprehend the underlying mechanisms and design effective policy interventions. Policymakers must carefully consider these mixed findings and tailor their strategies accordingly to promote both health and productivity in the long term. It is crucial to strike a balance between immediate gains and sustainable long-term outcomes. , Thesis (Masters) -- Faculty of Economics and Financial Sciences, 2023

- Description: Marketers throughout all industries are investing enormously towards developing and promoting green products and the retail sector is not exempted from this growing trend. The study aimed to investigate the influence of green marketing mix elements (green product, green price, green promotion and green distribution or place) on sustainable consumption and customer loyalty. To achieve the objective, the research study employed a positivist research paradigm anchored by a quantitative approach using descriptive research design. A structured self-administered survey questionnaire was randomly distributed to retail customers of a sample size of 265 respondents. The data was analysed using SPSS for descriptive statistics and Smart PLS for Structural equation modelling. The key findings reveal that all five hypothesised relationships are positive, however, only four are significant. The strongest relationship was found between sustainable consumption and customer loyalty (β=0.432) while the weakest (yet positive) relationship was between green place and sustainable consumption (β=0.078). The study equips the retailers about the key predictors of consumers’ green sustainable consumption behaviour enabling them to tailor their product offerings and formulate marketing strategies to encourage green buying behaviour. The current study can further assists policymakers to ground their discussions when developing regulations that govern how retail industries should promote, price and distribute their green products. , Thesis (Masters) -- Faculty of Economics and financial Sciences, 2023

- Description: Economic growth is regarded as one of the prime macroeconomic objectives of any economy. The study aimed to investigate the determinants of economic growth in South Africa for the period 1994 to 2021 using yearly data obtained from World Bank and IMF. The analysis of all the variables has been provided to show the relationship that the variables have with economic growth in the South African economy. The independent variables used were capital stock, financial development, employment and inflation. In achieving this aim, an Autoregressive Distributive Lag (ARDL) was used since it examines both the short-term and the long-term dynamics of the determinants of economic growth. In addition, Granger causality was used to determine whether the explored variables were causally related to one another. In the long run, the results point out that financial development was significant at 5%, while capital stock and employment were significant at 10%. In the short run, all variables were significant at 1%. The study recommends employment stimulation, investment in capital stock and financial development in order to boost economic growth. , Thesis (Masters) -- Faculty of Economics and Financial Sciences, 2023

- Description: Breaking bad news to patients is a difficult but regular task for doctors in clinical practice (Alshami et al. 2020). In paediatrics, doctors have the additional complexity of communicating difficult information with their young patients and their families (Mǎrginean et al. 2017). Despite this essential skill, clinicians are inadequately prepared, which can contribute to poor patient satisfaction and outcomes, litigation and negatively impact the treating clinician (Brown et al. 2009; Alshami et al. 2020). Aim: The study aimed to assess the knowledge regarding breaking bad news, as well as the attitude and perceptions towards breaking bad news among doctors working in the paediatric department at Dora Nginza Hospital, a regional teaching hospital in Gqeberha, South Africa, and compare the findings to the international literature. Approach: A mixed methods knowledge, attitudes and perceptions study using a self-administered questionnaire was conducted at the paediatric department at Dora Nginza Hospital. The survey population ranged from junior doctors to senior specialist paediatricians in the department. Data were analysed using descriptive statistics and compared to literature available from similar international studies. Impact of study: Despite the importance of this topic, there are limited studies based in South Africa and specifically in paediatrics, which creates a unique context for this study. The setting of Dora Nginza Hospital, with its diverse cultural background of both doctors and patients, provides vital insight into the local 3 challenges of breaking bad news in this context. The further impact of the predominantly junior staff in an overburdened system and the strategies implemented to break bad news in this context provided useful information to adapt protocols to be utilised in this setting. , Thesis (Masters) -- Faculty of Medicine and Health Sciences, 2023

- Description: Small businesses in South Africa are recognized for creating jobs and increasing economic growth. Ever since South Africa experienced load shedding in 2008, small businesses, especially those in the restaurant sector, have been hugely affected by load shedding as they heavily rely on electricity for most of their business operations. Load shedding results in a loss of sales and a decrease in productivity, which reduces their profitability and eventually, sustainability. The purpose of the study was to establish the extent to which load shedding affects the performance of small-scale restaurants in Mthatha, South Africa. A positivist research paradigm was adopted for the study, which was anchored on a quantitative approach using an explanatory research design. A fully structured self-administered questionnaire was sent to 53 small-scale restaurant owners or managers and 51 responded. Data analyzed using SmartPLS4 revealed that load shedding has a negative but insignificant impact on both the profitability and productivity of small-scale restaurants. Based on the results load shedding does not impact the performance of small-scale restaurants in Mthatha as both performance proxies showed a statistically insignificant impact. Looking at the current situation of electricity in South Africa, things are getting worse as it is common for Mthatha people to go the entire day without electricity. This study helps in identifying the extent of the effects load shedding has on small-scale restaurants. This study adds to the findings of prior research on the effects of load shedding on the performance of small-scale restaurants and the study contributed to the body of iii knowledge on the effects of load shedding on the performance of small-scale restaurants and mitigates on existing literature gap where the populace is not aware of the extent to which load shedding has affected the performance of small-scale restaurants. , Faculty of Economics and Financial Sciences, 2023

The study mainly concentrated on collecting the analysed data from principals, deputy principals and heads of departments of secondary schools of Qumbu magisterial district on the basis of my proximity to their schools. A case study research design was adopted as only principals, deputy principals and HODs officially employed by the Department of Education to teach in geographically located secondary schools in Qumbu magisterial district were used as subjects to collect data. The qualitative research approach was employed in this study. A sample of 15 participants who were chosen using purposive sampling were interviewed face-to-face adopting semi-structured interviews to gather data for this study. The findings supported SMTs' use of monitoring curriculum implementation methodologies, but their actual implementation was characterised by a lack of rigour and decisiveness. Evidently, a number of contextual circumstances influenced to what extent the methods that had been decided upon were carried out. It emerged that in some SMTs’ strategies to manage and monitor the quality of teaching and learning in their secondary schools, teacher unions disrupts such systems. This implies that the teacher unions play a detrimental role in limiting effective intervention strategies by management. As long as teacher unions plays a powerful role in tying the hands of management in quality control oversight, management will find it very difficult to make inroads into improving commitment by teachers and progress of learners. The Department of Basic Education and government need to review and revise the powers of teacher unions. , Thesis (Masters) -- Faculty of Education, 2024

- Description: Many Sub-Saharan African countries are endowed with natural resources and yet their public debts are keeping on ballooning. The skyrocketing of these debts can cause a public debt crisis which can further bite on the poor who are already living miserable lives in resource-rich countries. This study examines the impact of natural resource rents on public debt in Sub-Saharan African (SSA) countries from 2000 to 2020, utilising the panel ARDL technique. The main objective of this research work was to investigate the relationship between natural resource rents and public debt in selected resource-rich Sub-Saharan African countries. The panel ARDL technique employed in this study strengthens the analysis by considering both short-run and long-run dynamics. In the short run, a significant and negative relationship is observed between natural resource rents and public debt, aligning with the theoretical expectations of resource-rich economies benefiting from increased revenues. However, in the long run, a contrasting pattern emerges, indicating that natural resource rents contribute to an increase in public debt, highlighting the challenges associated with the resource curse phenomenon. The empirical analysis reveals noteworthy findings with implications for theory, practice, and policy. The findings underscore the need for careful fiscal management and prudent policies in resource-rich countries to avoid excessive debt accumulation over the long term. This highlights the importance of implementing effective governance mechanisms, transparency, and accountability frameworks to manage natural resource revenues responsibly. In conclusion, this study contributes to the understanding of the relationship between natural resource rents and public debt in SSA countries. It emphasizes the importance of balancing short-term fiscal benefits with long-term sustainability and provides valuable insights for policymakers to design and implement effective resource management strategies. , Thesis (Masters) -- Faculty of Economics and Financial Sciences, 2023

However, in the long run, a contrasting pattern emerges, indicating that natural resource rents contribute to an increase in public debt, highlighting the challenges associated with the resource curse phenomenon. The empirical analysis reveals noteworthy findings with implications for theory, practice, and policy. The findings underscore the need for careful fiscal management and prudent policies in resource-rich countries to avoid excessive debt accumulation over the long term. This highlights the importance of implementing effective governance mechanisms, transparency, and accountability frameworks to manage natural resource revenues responsibly. In conclusion, this study contributes to the understanding of the relationship between natural resource rents and public debt in SSA countries. It emphasizes the importance of balancing short-term fiscal benefits with long-term sustainability and provides valuable insights for policymakers to design and implement effective resource management strategies. , Thesis (Masters) -- Faculty of Economics and Financial Sciences, 2023

- Description: Hypertensive disorders in pregnancy (HDP) are the world's second leading cause of maternal mortality and morbidity, with sub-Saharan Africa taking the lead. The prevalence of HDP in Africa is 10%, remarkably higher than the reported global range of 5.2-8%. This study aimed to determine the prevalence and associated risk factors of CT-confirmed neurological complications in patients managed at the labour ward at Nelson Mandela Academic Hospital (NMAH) over two years. Methodology: A retrospective cross-sectional study was conducted on obstetric patients with clinical files at NMAH from January 2018 to December 2020. We tracked and merged hospital admission data and radiological (brain CT) findings in patients managed for HDP at the labour ward at NMAH within the specified period. Descriptive analysis, bivariate and multivariate logistic regression analysis was performed to identify associated clinical risk predictors of neurological complications. Major findings: Of the 5119 patients with HDP, 153 underwent CT scans. Our study found that 78.2% of the scanned patients with HDP were between 18 and 34 years old. Patients younger than 18 years accounted for 10% of the 154 patients who underwent CT-scan. We found that 81.1% had abnormal CT-brain findings, while 18.9% were normal. The most common abnormal finding was posterior reversible encephalopathy syndrome (PRES) (25.1%), followed by cytotoxic oedema (16,5%), neurocysticercosis (15.1%), and dural sinus thrombosis (7.9%). The most common neurological findings on admission were headache (82%), low GCS (60.1%), fits (55.6%), blindness (28.8%), and focal signs (11.5%). In addition, the following risk predictors were statistically associated with PRES: post-partum onset ( aOR=6.26,95% CI 1.02-38.83, p-value0.049 ), blindness (aOR=3.19, 95% CI; 1.07-9.59, p=0.038) and fits (aOR=0.20, 95% CI: 0.64-0.63, p-value=0.006. Recommendations and clinical implications: The most common radiological finding among obstetric patients with HDP in this study is PRES. The most significant risk predictors for PRES are the post-partum onset of symptoms and blindness. As PRES is | 3 associated with significant morbidity and mortality, vigilance and aggressive management should be continued and include the post-partum period. , Thesis (Masters) -- Faculty of Medicine and Health Sciences, 2023

- Description: The primary intention of this study was to explore the extent to which private tutorials relate to Euclidean Geometry performance amongst Grade 12 learners from selected schools in OR Tambo Inland District. The first objective was to examine the correlation between private tutorials and Euclidean Geometry performance. The second research question was to investigate the Euclidean Geometry means scores of students who attend private tutorials as compared to the group of students who do not attend private tutorials. The study had a sample size of 347 participants from four schools. Lev Vygotsky's Socio-cultural Theory was used as a theoretical framework to underpin the study. The study adopted quantitative research methodology to answer the research questions. A questionnaire and a standardised Euclidean Geometry test were administered to collect the data from the participants. Correlational and regression analysis were performed to analyse to data. The outcomes of the study reveal that private tutorials and Euclidean Geometry performance were significantly correlated. Furthermore, private tutorials were found to be the determinant or predictor of performance in Euclidean Geometry. Secondly, students who are attending private tutorials significantly outperformed their counterparts (i.e., students who are not attending private tutorials) in Euclidean Geometry. Recommendations were made to implicate stakeholders to enhance the effective use private tutorials to boost Euclidean Geometry performance while also improvising alternative measures to students who might want to attend private tutorials, but affordability becomes a detrimental hindrance. , Thesis (Masters) -- Faculty of Education, 2023

- Description: This study demonstrates that high energy milling using a planetary disc mill offers a new simple route to the production of polycrystalline silicon nanoparticles which are suitable for electronic applications. By manipulating process variables such as milling duration and mass of the feedstock load, the microstructure of the nanoparticles can be tuned to meet requirements. The internal structure of the nanoparticles prepared by high energy milling was found to predominantly consist of nanocrystalline silicon and their surfaces are characterised by a disordered layer of silicon sub-oxides and an insignificant proportion of fully oxidized silicon. X-ray diffraction (XRD) patterns and Raman spectra were used to calculate the average crystallite size and correlating it to the milling process variables. The surface chemistry of the nanoparticles was elucidated using X-ray photo spectroscopy (XPS) and was also related to the milling parameters. The internal structure, agglomeration and aggregation of the particles were tested using high resolution transmission microscopy (HRTEM) and complemented by scanning electron microscopy (SEM). Conductivity tests were done on the particles to ascertain their suitability for electronic applications. It is demonstrated that the longer the milling time, the smaller the sizes of particles and crystals. The sizes also depended on the mass of feedstock load. 30 g feedstock loads resulted in average nanoparticle size which were 30 - 40 % larger than for 10 g loads. The average size of nanoparticles produced were in the range 50 – 80 nm as measured by SEM. The distribution of the size of particles became less polydisperse with increase in milling time and a reduction in feedstock load. The particles were devoid of significant SiO2 layer and hence were confirmed by conductivity tests to be electrically active. Data from XPS indicate that the silicon nanoparticles have a unique surface chemistry which is consistent with the silicon surfaces being dominantly oxygen terminated. , Thesis (Masters) -- Faculty of Commerce and Administration, 2022

- Description: In-service teachers’ lack of adequate instructional approaches to effectively teach geometric concepts and poor learner performance in geometry were the major rationale for this study. The preparedness of in-service mathematics teachers cannot be overlooked. The aim of this study was to develop in-service mathematics teachers’ skills for integrating GeoGebra in the teaching of geometry in a multiple case study of secondary schools in Oliver Reginald Tambo Inland district. The researcher employed ICTs in education, GeoGebra as a learning object, and in-service teachers as conceptual framework that undergirded the study. For the theoretical framework, this study utilised the Technological Pedagogical and Content Knowledge (TPACK), Constructivist Learning Theory, and the Teaching Change Frame (TCF). This study focused on the technological components of the TPACK framework, such as Technological Knowledge (TK), Technological Content Knowledge (TCK), Technological Pedagogical Knowledge (TPK) and TPACK. The researcher found that constructivism is consistent with the TPACK framework. The implementation of the TPACK was guided and assessed using the Teaching Change Frame. Regarding the methodology, the study followed the pragmatic paradigm and utilised mixed method research following the concurrent triangulation design. Due to the nature of the study, the quantitative method in this study had dominance over the qualitative method. The study was conducted in schools situated in OR Tambo Inland district in Eastern Cape Province of South Africa. Purposive sampling method was adopted to sample twelve schools, in the ratio of seven urban to five rural schools. The sample consisted of 29 secondary mathematics in-service teachers, 20 from urban schools and nine from rural schools. The TPACK questionnaire, training lesson evaluation form, observation schedule checklist and interview were used to collect data. Reliability and validity were ensured through Cronbach’s Alpha reliability test and a pilot study, whereas data trustworthiness was ensured through qualitative measures including member checking. Findings revealed that the intervention to integrate GeoGebra in geometry teaching impacted positively on in-service teachers with a highly statistically significant and a gain of medium to large effect size on pre- and post-intervention. Thus, the positive impact of using GeoGebra in geometry teaching resulted in significant differences before and after the training of in-service teachers. The findings obtained from the training showed that in-service mathematics teachers developed skills of integrating GeoGebra software in their teaching of geometry. After the training, participants felt that integrating GeoGebra in geometry teaching afforded mathematics teachers the opportunity to use learner-centred approaches, teach geometry with confidence, maintain learners’ attention and alertness in class, and improve learners’ performance. Further, findings obtained from observing participants demonstrating their experience in integrating GeoGebra showed that, not only did in-service teachers’ confidence of using GeoGebra improve significantly, but also their ability to use GeoGebra to set geometry questions. The researcher also observed that integrating GeoGebra when teaching geometry had positive effects on teachers’ understanding of geometric concepts. The findings showed significant difference in participants’ confidence in delivering lessons that can combine technology (T), geometry content (C), and pedagogical (P) knowledge. As a contribution, recent literature has been added to the existing body of knowledge in teacher education related to technology integration studies. Among them is the invention of a new teacher training model called Technology Integration Model for Teaching and Learning. Establishing a GeoGebra institute in teacher training institutions, and engaging Department of Basic Education (DBE) or provincial or district curriculum specialists to train mathematics teachers to integrate GeoGebra were recommended for policy and practice. For further research, the study recommends following-up on trained in-service teachers to track their adoption of GeoGebra in geometry teaching, learner’s performance in geometry, and their perceptions of being taught geometry using GeoGebra. , Thesis (D.Ed) -- Faculty of Education Sciences, 2023

- Description: The 2000 to 2020 relationship between oil prices, exchange rates, and foreign direct investment (FDI) in South Africa presents a fascinating case in the global economics. Noteworthy is that this period is marked by some important geopolitical events, technological advancements, and economic shifts that provide a rich ground for analyzing how these three critical factors interact in an emerging country. South Africa, with its unique economic and political landscape, offers an exemplary context for exploring the dynamics of these variables and their collective impact on the nation's economic health and growth. This study conducted an empirical analysis to investigate the association of oil prices, exchange rates, and foreign direct investment (FDI) in South Africa from 2000 to 2020. The research applied the autoregressive distributed lag bounds technique (ARDL) after initial unit root tests indicated different orders of integration (1(0) and 1(1)) for the variables. The results align with the risk aversion theory, revealing a significant and negative relationship between exchange rates and foreign direct investment in the long-term. Conversely, the interaction term EXCH_OIL, interest rates, and inflation demonstrated a significant and positive relationship with foreign direct investment in both the short-run and the long-run. The Granger causality test identified a unidirectional causality from foreign direct investment to exchange rates. This study recommends implementing policies aimed at stabilizing oil prices and exchange rates to entice foreign investment into South Africa. , Thesis (Masters) -- Faculty of Economic and Financial Sciences, 2023

- Description: Financial inclusion has been regarded as a solution to the problem of poor economic well-being by providing quality access to financial services. It also contributes to resource and income distribution and boosts consumption and investment, which lead to an overall stimulation in economic well-being. The aim of the study was to examine the relationship between financial inclusion and economic well-being in South Africa. To achieve this, the study examined the long-run and short-run relationships between financial inclusion and economic well-being in South Africa using quarterly time-series data from 1992 to 2020. The data was obtained from World Bank economic indicators and a SARB statistics enquiry. The study used the Autoregressive Distributed lag bound test and the Error Correction Model to examine the long-run and short-run relationships of the variables. The Granger causality test was conducted to identify the directional causality amongst the variables. The variables used in this study were GDP per capita (GDPPC) as a measure of economic well-being, which is the dependent variable, whereas bank account holders, access to credit, and insurance were used as major explanatory variables. The study discovered that in the long-run, bank account holders and access to credit have a positive significant relationship with GDP per capita, whilst inflation rate indicated a negative relationship with GDP per capita. However, in the short-run results, the study revealed that insurance and inflation rate have a positive relationship with GDP per capita, whereas access to credit presented a negative relationship with GDP per capita. The Granger causality test only indicated a bi-directional causality between inflation rate and GDP per capita. A diagnostic test was conducted in the model and the results revealed that all instruments used in the model are valid and reliable. Based on these findings, the existence of a positive relationship between financial inclusion and economic well-being can be confirmed, hence validating the hypothesis in South Africa. This study recommends that government and policy-makers should focus more on accelerating the expansion of access to credit and insurance at lower transactional costs and management fees, especially for the poor and most vulnerable population in the country. Furthermore, the access to credit, insurance and economic well-being relationship should take place in an inflation framework-sensitive environment. , Thesis (Masters) -- Faculty of Economics and Financial Sciences, 2023

- Description: Financial inclusion has been regarded as a solution to the problem of poor economic well-being by providing quality access to financial services. It also contributes to resource and income distribution and boosts consumption and investment, which lead to an overall stimulation in economic well-being. The aim of the study was to examine the relationship between financial inclusion and economic well-being in South Africa. To achieve this, the study examined the long-run and short-run relationships between financial inclusion and economic well-being in South Africa using quarterly time-series data from 1992 to 2020. The data was obtained from World Bank economic indicators and a SARB statistics enquiry. The study used the Autoregressive Distributed lag bound test and the Error Correction Model to examine the long-run and short-run relationships of the variables. The Granger causality test was conducted to identify the directional causality amongst the variables. The variables used in this study were GDP per capita (GDPPC) as a measure of economic well-being, which is the dependent variable, whereas bank account holders, access to credit, and insurance were used as major explanatory variables. The study discovered that in the long-run, bank account holders and access to credit have a positive significant relationship with GDP per capita, whilst inflation rate indicated a negative relationship with GDP per capita. However, in the short-run results, the study revealed that insurance and inflation rate have a positive relationship with GDP per capita, whereas access to credit presented a negative relationship with GDP per capita.

- Description: The relationship between trade openness and government size has drawn interest in the domains of public policy and economics. To add to this discourse, the current study conducts an empirical analysis using annual data covering the years 1994 to 2020, focusing on South Africa as the case study. By analysing the complex dynamics between trade openness and government size, this study aims to offer an insightful analysis of the economic landscape and shed light on the implications for government policies. An autoregressive distributed lag (ARDL) model was utilized in the study, allowing for a thorough analysis of the short- and long-run relationship between trade openness and government size. The empirical findings indicate a substantial positive relationship between trade openness and government size. Moreover, the Granger causality demonstrates that trade openness and government size in South Africa have a unidirectional causal relationship, which further solidifies this relationship, aligning with theoretical literature's compensation hypothesis. Based on the findings indicating a substantial and positive relationship between trade openness and government size, as well as the Granger causality research supporting the compensation hypothesis, certain policy implications emerge. To optimize economic outcomes in South Africa, policy-makers could focus on implementing trade liberalization policies to reduce barriers and promote free trade agreements, facilitating economic integration and access to new markets. Additionally, attention to prudent public expenditure management becomes crucial, ensuring that increased government size is accompanied by efficient allocation of resources to foster economic growth and development. , Thesis (Masters) -- Faculty of Economics and Financial Sciences, 2023

- Description: The aim of the study was to explore the roles that principals play in the functionality of the South African schools. The Instructional Leadership Theory was used, and a case study design was followed. Detailed individual and group discussions were done to get rich data from 5 participants from 5 purposively carefully chosen high schools. Through thematic analysis of the interviews, three major findings emerged. One of the key findings was that school principals in this study relied overwhelmingly on the old knowledge they acquired from their junior degrees, and from observations, to lead the schools. As such, there was a leadership gap in their daily execution of roles. This study concludes that school principals are not as capacitated and well developed to perform their everyday roles in South African schools. It was recommended that the Department of Education offer on-going development plans to up-skill the school principals so that they can be professional and administratively ready for their roles. , Thesis (Masters) -- Faculty of Education, 2023
