  • Description: Many small business owners struggle to keep their businesses operational due to a lack of financial support. It is unclear whether South African development finance institutions (DFIs) are effective in providing such support to small businesses. The primary objective of this study is to investigate how effective South African DFIs are in fostering sustainable growth in small business enterprises through their financial and non-financial support services. The Gauteng Enterprise Propeller (GEP) is used as a case study. This study is located in the positivistic research tradition and therefore followed a quantitative research approach. Closed-ended questionnaires were distributed to 150 small businesses who were funded by the GEP. Self-constructed instruments were used to measure the independent variables and the dependent variable of the study. Multiple regression analysis was conducted to investigate the hypothesised relationships. Empirical results were that the participants largely disagreed (average mean score of less than two on a five-point scale) that the GEP frequently provides financial and non-financial support to small businesses. The results also demonstrate that the GEP’s marketing material, planning support, financial management and asset acquisition interventions were significantly related to the perceived business success of the sampled small businesses, while operational support interventions were not significantly related. On both a theoretical and practical level, the study adds to the knowledge of which financial and non-financial support interventions play a significant role in the success of small businesses. With the contribution of this study, South African DFIs can improve their financial and non-financial support strategies to assist small businesses in growing their operations. The study also provides a practical assessment of how GEP support recipients experience such support. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2023

  • Description: Oil and gas exploration must have firm and clear environmental protection legislation as a blue economy industry. The Ministry of Mines and Energy regulates offshore oil and gas explorations in Namibia, and this is complemented by the Ministry of Fisheries and Marine Resources, the Ministry of Environment Forestry and Tourism, and the Ministry of Works and Transport to ensure that associated environmental impacts are minimised or mitigated. They govern the environmental protection of offshore oil and gas exploration with one regulation, seven policies, and ten legislations. While these regulations are individually good as they show consideration for most environmental impacts associated with oil and gas explorations, implementation remains challenging due to fragmentation in mandates among the key ministries. A qualitative research approach was used to meet the project objectives. Legislation documents, policy documents, the blue economy, and oil and gas literature were reviewed and interpreted, and they thus provided the content that was analysed to answer the research questions. Which aimed at examining the environmental protection regulations addressing environmental impacts associated with offshore oil and gas exploration in Namibia. Two main environmental impacts were identified, oil spills and underwater noise pollution. While there is adequate consideration for oil spills in the Namibian legislation, there is no specific consideration for underwater noise pollution, a significant environmental impact from offshore upstream activities. Recommendations were made to improve the implementation of environmental protection measures and develop national legislation for mitigating underwater noise pollution. Involving locals (Namibians) in emerging industries, whether marine or not, is critical in identifying environmental threats and socio-economic opportunities, thereby making for an inclusive sector as the blue economy concept intended. , Thesis (MPhil) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 2023

  • Description: The mixed methods action research study explored how collaborative writing and scaffolding practices impacted on the writing performance of students writing in groups. It sought to establish whether using the collaborative writing (CW) method would enhance the writing performance of 55 social work Midlands State University first-year students. Socio-cultural theory (SCT) was employed as the theoretical basis for the study as it emphasises learning in socially constructed environments in which interaction among peers and teachers leads to learning and construction of knowledge. Through the examination of student interactions in two collaborative writing activities, an analysis of student perceptions of CW, and an assessment of student collaboratively produced texts, the study found that the different peer and teacher scaffolding practices that were employed in the collaborative writing sessions significantly enhanced the students’ writing performance. Regardless of the challenges identified in CW, for example, misunderstandings and meaningless contributions from some group members, the research findings revealed that the student interactions offered scaffolding to support their writing activities. For example, validation feedback, link to previous knowledge and the use of correctional feedback were the scaffolding practices used. In addition, the students were able to collaboratively produce better texts with improved cohesive linking, mechanics, organisation, development, structure and vocabulary. The study contributed to L2 collaborative writing literature as it identifies the different student scaffolding approaches and offers an insight into the collaborative writing process and how it could support ESL writing development. However, the methodology posed some limitations, for example, the use of a questionnaire instead of interviews and recording student interactions in a journal instead of audio recording and, lastly, the researcher struggled to balance research demands and her normal teaching load. The study recommends the monitoring of students in CW groups, facilitation of peer/teacher motivation, establishment of group norms and formation of small groups with a maximum number of six members. , Thesis (MA) -- Faculty of Humanities, 2023

  • Description: The paper’s primary goal is to investigate the impact of the Knowledge Economy on the Economic Complexity in Africa. The paper presents the concept of the knowledge economy, an economy where knowledge is the main engine of economic growth and a measure of the knowledge in a country as expressed in the diversification of its products (Economic Complexity). It highlights the knowledge economy framework by the World Bank, which asserts that sustained investments in education, innovation, information and communication technologies, and a conducive economic and institutional environment will lead to increases in the use and creation of knowledge in economic production. Summary findings on machine learning estimates proved method LASSO has the minimum SE, which shows that the method LASSO forecasts the model with much precision than the other methods. The panel quantile regression results designate that the education component, ICT, economic incentives tend to affect ECI significantly and positively, while government indicators and innovation play a partial role. , Thesis (MCom) -- Faculty of Business and Economic Science, School of Economics, Development and Tourism, 2023

  • Description: The exchange rate and political instability are crucial macroeconomic variables strongly related to every economy. In South Africa, exchange rate fluctuations are widely related to major political events. The study analyses the fluctuations in exchange rates by applying exchange rate data over the period 1989 to 2020. The current study, used the predictive quantitative design that combines correlational analysis with predictive modelling. The Unit root results show that political instability and exchange rate are stationary at first difference, and inflation, GDP, political instability, the rule of law, and corruption control and corruption freedom are stationary at level. The Vector Auto Regression model (VAR) was applied to examine the short-run relationship between political instability exchange rate, GDP, inflation, real interest rate, corruption and the rule of law. The results show a short-run relationship between political instability, exchange rate, GDP, inflation, real interest rate, corruption and rule of law. Johansen Cointegration testing was also performed to establish cointegration between variables. The results from the Johansen tests suggest that the model presents a cointegration between political instability, GDP, inflation, real interest rate, corruption and the rule of law and exchange rate, implying that these variables are related and can be combined linearly. The VECM was performed to establish a long-run relationship between variables since cointegration was established between variables. The Vector Error Correction (VEC) model complemented these findings resulting in the null hypothesis that states there is no long-run relationship between variables being rejected. The alternative hypothesis that there is a long-run relationship between variables was accepted. The Granger Causality test was performed to examine the causality between variables and to examine the drivers and causes of exchange rate fluctuations in the VAR model. The results revealed that political instability does not Granger cause exchange rate fluctuations in the short run and that there is a negative relationship between political instability and exchange rate fluctuations. The short-run results revealed that the exchange rate does not Granger cause political instability. However, the exchange rate Granger causes the country's political instability in the long run. This study’s literature review found that political instability harms exchange rates and the economy, and its impact can be felt globally. The results of the study show that there is a negative relationship between political instability and exchange rates. In the short run, the results show that political instability Granger causes inflation. The impulse response function (IRF) was conducted to determine the shock of political instability on the exchange rate. The findings indicate that the magnitude of the shock refers to one standard deviation. The results show that after two years, 92% of the shock in exchange rates is due to the shock on the exchange rate itself, and only 0.12% is due to political instability in the short run. This means that the shock on the exchange rate is associated with the exchange rate itself. The result is consistent with empirical findings in South Africa that fluctuations, in the long run, are largely caused by political instability from corruption. The exchange rate results and the political instability response were used to calibrate the long-run response to exchange rate fluctuation. Political instability was also used to assess the nexus between political instability and economic growth. The results determine a positive relationship between political instability and economic growth. The IRF was performed to track the impact of a variable on other variables (that is, the exchange rate on political instability, GDP, corruption, inflation, real interest rate, the rule of law, and corruption) in the system from several periods in the future. The Autoregressive Integrated Moving Average (ARIMA) model for forecasting was selected because it provides an accurate forecast and satisfies the criteria for an ideal model. The results show that in the future, not much variation can be expected in the long run, meaning that political instability is projected to stabilise from 2021 to 2040, and the exchange rate will increase. The results from the analysis of exchange rates and political instability confirm the existence of a negative relationship between political instability and exchange rates. The findings of the study point to a need for the South African government to immediately respond to an increase in exchange rates and to stabilise the undercurrents caused by macroeconomic shocks. The study will contribute to the theoretical understanding of fluctuations in exchange rates and the formulation of macroeconomic stabilisation. , Thesis (PhD) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism , 2023

  • Description: Branding is crucial to increase and improve competitiveness in the contemporary market. Due to consumers' sophisticated and high standards for various branded items and services, marketers and organisations are now investing in branding to increase the visibility of their goods and services. All industries share this. The high demand for international footwear brands in Ghana has made the local market uncompetitive, causing many local footwear organisations to lose customers and income to their international competitors and ultimately leading to the failure of many local footwear organisations (Agyeman, 2013:24; Vidal, 2022:2). To save Ghana's declining footwear industry, a new footwear brand must be built. The commitment to the effective implementation of the new footwear brand will raise consumer awareness, improve its visual and cognitive image, and increase its competitiveness. The study investigated how footwear manufacturers could build a powerful brand to save Ghana's domestic footwear market. The study also examined how visual identity elements affected the new footwear brand identity development in Ghana's footwear manufacturing industry. The necessary sample was drawn using convenience non-probability sampling approaches, cluster sampling, and basic random probability sampling. A questionnaire was used in the study's quantitative research design to collect the primary data from a sample of 400 consumers who made footwear purchases at Ghana's three biggest malls: Kumasi City Mall, Accra City Mall, and Achimota Mall in the Ashanti and Greater Accra regions, respectively. The questionnaires were distributed to the respondents via email, then, IBM SPSS (version 28)and AMOS software were used to investigate the data. Descriptive statistics andinferential statistics were the two main types of analysis used for the primary data. These provided the frequency tables showing data structures, correlations showing relationships between variables, regressions showing visual identity elements as predictors of footwear brand identity in Ghana. From the empirical results, the visual identity elements: brand name, logo and symbol colour, slogan, and typography had a statistically significant relationship with the new footwear brand identity in Ghana. The results further reveal that brand awareness and brand image significantly measured the new footwear brand identity. , Thesis (DPhil) -- Faculty of Business and Economic Sciences, School of Management Sciences, 2023

  • Description: Exploring gender identity and ideology can broaden our comprehension of how gender roles and responsibilities are carried out, and how disparities may be experienced. It is critical to explore them, within research, to generate new insight into the views and positioning of individuals, within their intimate relationships. Therefore, the aim of this study was to explore and describe the perceptions of isiXhosa men about their roles and responsibilities in intimate relationships. The study was broken down into three objectives which were: to explore perceptions of their role within their relationship, to explore their perceptions of their responsibilities within their relationship; and to explore factors supporting change within the roles and responsibilities. The study took the format of an exploratory descriptive research design. Ten Xhosa men were selected as participants using snowball sampling, and semi-structured interviews were used to gather data. Data was analysed using Braune and Clarke’s (2006) reflexive thematic analysis. The study came to the conclusion that there are two main roles of Xhosa men in intimate relationship, namely: head of the house; and the provider. Three dominant responsibilities were found to be common among the participants, namely, making all main decisions, providing financial support, and responsibility to safeguard. The study also found factors causing Xhosa men to change their roles and responsibilities in intimate relationsh were unemployment, disrespectful partner, extended family needs, demanding job and inadequate income from work. Lastly, the study concluded that the extent to which the changes of the roles and responsibilities among Xhosa men may affect their intimate relationships include break-ups/divorce, domestic violence, dysfunctional families – fragmentation of families and mental and emotional health issues. , Thesis (Ma) -- Faculty of Health Science, 2023

  • Description: Business continuity does not happen by chance, it is rather enabled or propelled by various activities in business operations. This study examines the role of dynamic capabilities and enterprise risk management and their role in the continuity of Small, Micro and Medium Enterprises (SMMEs) in the Nelson Mandela Bay Metropolitan Municipality. Fixated in the positivist paradigm, this study adopted a quantitative research approach to collect data from 105 SMMEs registered with the Nelson Mandela Bay Business Chamber, who were sampled using stratified and convenience sampling. Data was collected via an online survey on Google Forms and analysed using SPSS version 23. Descriptive statistics and statistical analysis methods were applied using SPSS version 23. The analysis was done in three phases. Firstly, the researcher conducted a reliability analysis of the questionnaire, and secondly, a descriptive statistical analysis to examine the research questions. The third phase was a statistical analysis to test the hypothesis. A Pearson‟s correlation test was performed to test the relationship between dynamic capabilities and enterprise risk management. The findings showed that, as enterprise risk is managed, dynamic capabilities increase, and thus there is a significant relationship between dynamic capabilities and enterprise risk management. The correlation between the variables which measured the dynamic capabilities and those which measured enterprise risk management seemed to be significant as they were all above 0.05. Therefore, it can be concluded that dynamic capabilities and enterprise risk management contribute to business continuity. This means that dynamic capabilities enhance business continuity, dynamic capabilities enhance enterprise risk management and enterprise risk management enhances business continuity. To leverage these positive relations, SMMEs ought to employ ERM experts or engage ERM consultants who will design Enterprise Risk management (ERM) strategies that are compatible with their enterprises. It is also recommended for SMMEs to have quarterly evaluations of the Enterprise Risk Management strategies and Dynamic Capabilities that enhance their business continuity planning , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2023

  • Description: Richard Branson reportedly said that “if you ask any successful business person, at some point along the road, they will always have had a great mentor”. The lack of representation of females at senior and executive levels is slowly transforming, yet not at the required rate. The study was conducted to evaluate the role of mentoring in the advancement of female leadership in corporate organisations. The research method that was followed was a qualitative and explanatory inductive approach to interview participants and observe their experiences and opinions with regard to the role of mentoring in the advancement of women through the following themes: job satisfaction, organisational culture, organisational development mentoring and the barriers and challenges that affect women. The focus area includes women in current senior level positions who have aspirations to advance into more senior or executive levels. Semi-structured interviews were conducted with participants and due to the COVID-19 pandemic that has affected the globe, a small group of well-respected individuals was selected according to their credibility. The key observations reflected within the study that the themes which were dominant included the following: 1)inequality, 2) lack of support and the importance of a sponsor/coach and 3) barriersand challenges (the “glass ceiling” and “boys club”) that still exist. The findings of the study will equip the role players within corporate organisations and associated bodies to ensure mentoring is used and encouraged for adoption among all organisations, implement mentorship strategies and apply the ADAPT mentoring model. Furthermore, the findings will serve to bring relevant insights and recommendations to promote more women in senior, executive and board-level positions. The implications of the findings suggest that mentoring is an enabler of advancement leverage for female leadership into senior and executive levels. The limitations of the study were the effects of COVID-19 and the subsequent countrywide lockdown, where constraints of meeting in person, availability of time, network and data constraints availed themselves. The researcher was unbale to ascertain long-term effects of the role of mentoring in advancing female leadership, but rather encourages its main benefits and is positive of the influence it may hold to set a precedent. The study established that the ability to create spaces of empowering women in corporates builds strong, economically viable corporates that promote mentoring to advance female representation. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2023

  • Description: Public sector construction projects in South Africa are not always implemented successfully as a result of professional non-compliance in the construction industry by professionals entrusted with the responsibility to deliver construction projects. Professionals in the construction industry registered with the built environment regulatory bodies must demonstrate professionalism in terms of competency and conduct when carrying out their professional duties as prescribed by the relevant regulatory bodies they belong to. This study utilised a qualitative case study to investigate the state of professional compliance during project implementation in a selected construction industry in Gauteng. A purposive sampling method was adopted to select participants with at least two years’ experience in managing public sector construction project implementation in Gauteng, resulting in 11 participants in the study. Semi-structured interview questions were designed and put to the participants during telephonic interviews. The research findings suggest that professional competency and conduct compliance requirements which contribute to effective project implementation include a relevant qualification as an initial step to become professional in the construction industry, followed by work experience, knowledge and registration with relevant regulatory and professional bodies which also require registered professionals to abide by their ethics and code of conduct. The findings suggest that the forms of non-compliance in terms of professional competency and conduct affecting effective project implementation were the result of a lack of experience or knowledge of construction professionals in relation to the project, poor quality of work and professionals’ neglect of duties. The perceived types of professional non-compliance affecting effective project implementation in the construction industry revealed by the findings included amongst others, breach of obligations, corruption, bribery and fraud, conflict of interest and carelessness; and factors of professional non-compliance such as high discounts, community disruptions, junior staff not been monitored, political relations and competition. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2023

  • Description: The purpose of this study was to determine if the African Union can achieve sustainable and inclusive growth through the adoption of a feminist political economy framework. This was done by investigating the potential gendered impact of the recently operationalised African Continental Free Trade Area (AfCFTA) on African women. The specific indicator of sustainable and inclusive growth utilised was the “income poverty and equity parameter”. Owing to the contemporary nature of the trade agreement, a historical analysis of gender mainstreaming efforts within African Regional Economic Communities was undertaken. This aided in determining the arbitrary treatment of gender provisions in regional trade initiatives. Additionally, a nexus was drawn between the role of African hegemonies and the disregard for gender sensitivity in trade policies. It was found that despite the existence of gender mainstreaming tools, the achievement of sustainable and inclusive growth by the African Union will be unattainable. , Thesis (MA) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 2023

  • Description: Pyrolysis process is one of the most efficient methods in the waste tyre recycling sector at this moment, hence the attention it is receiving. However, this process has some limitations, with the main one being that it is non-conventional and typically energy intensive. In addition, its resultant products have been reported to have significantly poorer properties relative to their virgin counterparts, making it difficult to incorporate them in the mainstream of raw materials. For instance, waste tyre pyrolysis oil typically has poor fuel properties, high sulfur content, high amount of polycyclic aromatic hydrocarbons (PAHs) and strong unpleasant odour; on the other hand, the quality of the recovered carbon black is dependent on the feedstock and the pyrolysis process conditions. Hence the need for further research and development to make the process effective and improve the quality of resultant products. The aim of this research project was to study the impact of pre-pyrolysis treatment of tyre crumbs and post-pyrolysis treatment of the oil using a novel chemical system on the quality/composition of the resultant products. In addition, the study compared the impact of pre- and post-pyrolysis treatments on the optimum pyrolysis time and temperature (energy). The equipment employed in this study included a vertical fixed bed pyrolysis pilot reactor (modified to suit the reaction/experiment) as well as characterization techniques such as fourier transform infrared (FTIR), elemental analysis (carbon, hydrogen, nitrogen and sulfur – CHNS analysis), gas chromatography coupled to mass spectrometer (GCMS), gas chromatography coupled to flame photometric detector (GCFPD), thermo-gravimetric and derivative analysis (TG/DTG isothermal analysis, and proximate analysis) and scanning electron microscope (SEM). The highlight of the findings is that chemically pre-treating tyre crumbs with a mixture of protonic acid and organic solvent before pyrolysis significantly lowered the temperature required to pyrolyze them, from around 400-500 ℃ to 100-115 ℃. This meant that by using the chemical treatment on waste tyres a lot of energy can be saved. In addition, the sulfur content in the oil fraction was reduced from a total of 1.7 wt% to a total of about 0.2 wt%. This also showed that the contaminants in oil were significantly reduced. The oil was condensed into three (3) collectors for fractionation; in collector 2 was about 54 % of the total oil with sulfur content of about 0.015 wt%. The PAHs amounts were also lowered, as literature indicated that PAHs are mostly formed at around 600-700 ℃. It was also found that the oil produced from post-pyrolysis treatment of oil has a petroleum-like smell, whereas the pre-pyrolysis treated oil has a tyre-like pungent odour. Furthermore, the post-pyrolysis treated oil contains higher contents of alkanes and benzene, toluene, xylene (BTX). Findings of this study have a profound potential impact on the waste tyre recycling industry; for example, reduced production energy cost due to lowered temperature required for pyrolysis, improved quality of the products such as lowered sulfur and PAHs content as well as improved quality of the residual char and odour. , Thesis (PhD) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2023

  • Description: The role of Traditional Birth Attendants (TBAs) has been within remote communities for a long time. TBAs remain a major health resource in rural communities in developing countries as well as in some parts of urban areas. South Africa is a long way from effectively utilising TBAs as a community resource to enhance access to maternity services. This qualitative study, with an explorative, contextual, and descriptive design, included ten (n=12) TBAs aged between 38 and 56 years who met the inclusion criteria and were interviewed for the study. The objective of the study was to explore and describe TBAs’ perceptions of their role in caring for women during childbirth in the Nyandeni Sub-district. Data for this study was collected using face-to- face and individual semi-structured interviews, and field notes. Recorded data was transcribed verbatim and analysed using thematic analysis. Three main themes emerged, namely: TBAs perceive their role in caring for women as an essential service to women in the community; they believe that they possess the knowledge to conduct deliveries safely; and acknowledge that collaboration with the Department of Health could strengthen rural midwifery services. , Thesis (Ma) -- Faculty of Health Science, 2023

  • Description: The sudden and immediate transition to online learning during the COVID-19 pandemic brought forth unprecedented challenges, particularly within the education sector. In Africa, this shift was necessitated by the need to safeguard lives and preserve the academic year. However, the absence of adequate contextual consideration introduced additional complexities, influencing how students in the African context navigated their learning experiences during this unique time.This study aimed to comprehensively synthesize the online learning experiences of university students in Africa amid the COVID-19 pandemic and evaluate the influence of these experiences on academic performance. Drawing from the systematic review protocol proposed by Hemingway and Brereton, seven (7) qualitative research articles were rigorously selected based on predefined inclusion criteria and meticulously examined.Thematic analysis of the chosen articles revealed two overarching themes. The first, "Emotional Distress," encapsulated students' experiences of anxiety, depressive emotions, and anger. Contributing factors included limited interaction opportunities, a sense of isolation, insufficient online learning resources, inflexible course structures, and non-conducive learning environments. The second overarching theme, "Growth," encompassed improvements in grades and enhanced self-directed learning abilities.These findings hold significant implications for the enhancement of online learning experiences in Africa. To address the challenges associated with emotional distress and foster growth, we propose the following recommendations: increased focus on social interaction and support mechanisms, equitable access to online resources, flexible course structures, and fostering conducive learning environments. , Thesis (MA) -- Faculty of Social Sciences and Humanities, 2023

  • Description: Climate variability has significant implications for crop production and overall food security. Climate services, which provide tailored and localised climate information, have the potential to enhance farmers' understanding of climate patterns and support informed decision-making. The purpose of the study was to assess the impact of climate services on smallholder farmers’ cropping decisions and household food security. The study adopted a cross-sectional household survey on 217 smallholder crop farming households from Elundini Municipality. Structured questionnaires and face-to-face interviews were used to collect the required data from the farmers. Descriptive analysis was used to identify the types of climate service accessed by smallholder crop farmers in the study area. The probit model was used to examine factors influencing smallholder crop farmers’ access to specific climate services. The household dietary diversity score was used to measure household food security among smallholder crop farmers. The propensity score matching model was used to assess the impact of accessing specific climate services on cropping decisions and household food security. The results indicated that most farmers 77 percent in the study area had access to climate services. The results further showed that many farmers had access to short-term weather forecast 79 percent with very few accessing seasonal forecast 22 percent. The results also revealed that access to both short-term weather and seasonal forecasts is positively influenced by ownership of mobile phones and access to extension services. Similarly, access to short-term weather forecasts is positively influenced by age, monthly income, ownership of radio, timely climate information, and perceiving that climate change has negative effects on crop production. Land size, knowledge of climate change, and climate services accuracy are positive and significant factors influencing access to seasonal forecasts. Most of the smallholder farming households in the study area had higher dietary diversity scores 66 percent. Moreover, access to short-term weather and seasonal forecasts has a positive and significant impact on cropping decisions and household dietary diversity scores. The study concludes that climate services improve cropping decisions and household food security among smallholder crop farmers in Elundini Municipality. The study recommends that there should be investments in awareness programmes that will educate farmers about the importance of climate services and how to acquire and interpret both weather and seasonal forecasts. Stakeholders interested in improving smallholder farmers’ access to climate services should consider whether farmers own smart phones and have access to extension services, arable land, knowledge of climate change, and if the climate services are accurate for smallholder farmers. In addition, to improve crop production and household food security in the face of climate change, access to climate services by smallholder farmers should be considered. , Thesis (MSc) -- Faculty of Science and Agriculture, 2023

  • Description: Ambidexterity is the capacity of an organisation to develop both exploration and exploitation capabilities simultaneously. These require different types of responses. This thesis investigates the role of ambidexterity in small and medium enterprises (SMEs). Ambidexterity is associated with network capability and value co-creation. In addition, SMEs can benefit from ambidexterity by reducing the risk of failure and promoting growth. The results suggest that ambidexterity in conjunction with networking partnerships and co-creation are key capabilities for small businesses. Secondly, they reveal that SMEs can develop ambidexterity by engaging in both formal and informal learning from their networking partnerships. This is important for policy makers because it suggests that government support for SMEs should focus on developing both formal and informal learning opportunities. Managers of SMEs should also focus on developing both formal and informal learning opportunities. It is an important capability for the success of these businesses. Networks can also be used as a learning mechanism by SMEs. Furthermore, the research also suggests that the use of digital technology networks can be beneficial for the development of ambidexterity. This means that SMEs should consider investing in digital technology networks to enhance their ambidexterity capabilities. Additional research is needed to determine the specific benefits that digital technology networks provide to SMEs. However, the findings suggest that digital technology networks can help to improve the development of ambidexterity. Although networks and co-creation may be necessary for SMEs, they should caution that openness to change can also be risky. It is essential to manage the risks associated with susceptibility to change. SMEs should consider investing in digital technology networks to help them manage these risk. , Thesis (PhD) -- Faculty of Management and Commerce, 2023

  • Description: Many Sub-Saharan African (SSA) countries experience low economic growth rate levels which is worrisome given the demographic window of opportunities in the region. The governments of SSA countries have been putting emphasis on increasing investments in human capital development as it is vital in unlocking potential economic growth through enhancing regional productivity. With this in mind, this study examined the effect of human capital investment on economic growth through productivity in 12 selected SSA countries during the period 2000 to 2017. The selection of these countries and the study period were based on the data availability as well as differences in income growth. The sample represents all the countries in the income growth groups which are low income, lower middle income and upper middle income. In order to examine the overall effect of human capital investment on economic growth the study utilizes two models which are: 1. Human capital investment and productivity in selected SSA countries. 2. Human capital investment and economic growth in selected SSA countries. Model 1 objective of the study was to investigate the effect of human capital investment on productivity in the selected SSA countries. Productivity proxied by labour productivity measured by real output per person employed was the dependent regressed against a host of independent variables which includes human capital investment, foreign direct investment (FDI), total factor productivity (TFP) and labour quantity growth (LQ).The human capital investment components used in the model included: fiscal expenditure on primary education (PEI), secondary education(SEI), tertiary education (TEI) all as a percentage of government expenditure on education; public health(PHI) as a percentage of GDP and domestic private health (DPHI) as a percentage of current health expenditure. Several estimation techniques which include the Pooled Mean Group (PMG), Panel Fully Modified Ordinary Least Square (PFMOLS) and Panel Dynamic Ordinary Least Square (PDOLS) were employed to analyse the relationship between the variables of interest. The empirical findings indicated that all human capital investment components contribute positively to labour productivity except tertiary education investment which had a negative effect. Moreover, the empirical findings also revealed that foreign direct investment and total factor productivity had positive effects on labour productivity while labour quantity growth had a negative effect. Model 2 objective examined the effect of productivity enhanced human capital on economic growth in the sample of countries. It also incorporated the direct channel of the effect of human capital on economic growth in the stated countries. Economic growth (EG) proxied by real GDP growth as the dependent variable and, on the other hand, explanatory variables being productivity enhanced human capital investment (PEHC), human capital (HC), gross fixed capital formation (GFCF), population growth (POP), institutional quality proxied by government effectiveness (GE) and political stability (PS). The same estimation techniques were also employed so as to obtain robust results. The empirical findings revealed that both productivity enhanced human capital investment and human capital contributes positively to economic growth in the selected SSA countries. In addition, the empirical results also proved that gross fixed capital formation, government effectiveness and political stability have positive effects on economic growth whilst population growth has a negative effect. Overall, the results of the study evidenced the existence of a transfer mechanism from human capital investment to economic growth through productivity in the selected SSA countries. The empirical results imply that increasing investment on human capital is of importance in trying to enhance productivity and through this economic growth in the SSA region. The study concludes that there is a potential on enhancing economic growth in the long run in the SSA region if countries invest more on human capital. Therefore, the study recommends that SSA countries must devote more budget to human capital so that free basic education can be offered in both primary and secondary as well as free health care services. With this, the objectives of quality education and health, sustainable and inclusive growth targets of the African Union (AU) Agenda 2063 as well as United Nations (UN) Sustainable Development Goals (SDGs) can be achieved. , Thesis (PhD) -- Faculty of Management and Commerce, 2023

  • Description: The study investigated the impact of financial integration on financial development and economic growth in the Southern African Development Community using annual data for the period 2000 to 2018. Literature shows that there is no universally accepted measure of financial integration hence the study utilized the Lane and Milesi-Ferretti measure, foreign direct investment as a percentage of GDP and Chinn-Ito (KAOPEN) index in achieving the objectives of the study. One of the main objectives of the study was to examine the impact of financial integration on financial development in the SADC community. The study utilized first difference GMM to achieve this objective and the results showed that Lane and Milesi-Ferretti measure and foreign direct investment as a percentage of GDP significantly affect financial development whilst Chinn-Ito (KAOPEN) index displayed an insignificant effect. The next step was to investigate the impact of financial integration on economic growth in the SADC region. To accomplish this objective, the study investigated both the direct channel as well as the possibility of financial integration indirectly influencing economic growth through financial development, trade openness, and institutional quality. The Three Stage Least Squares (3SLS) technique was utilized on a system of five simultaneous equations in examining the effect of financial integration on economic growth. The results revealed that financial integration affects economic growth both directly and indirectly. Regarding the indirect channels, only the financial development and institutional quality channel proved to be significant. To ensure the robustness of the results the study checked if the impact of financial integration was sensitive to the measure of financial integration and financial development used. The study employed KAOPEN to proxy financial integration while broad money supply (% of GDP) measured financial development. Robustness results confirmed that financial integration affects economic growth both directly and indirectly. This time, the trade openness channel was significant at 10% which shows the benefits through this channel are significant. This shows that the results of the trade openness channel are inconclusive. When the Lane and Milesi-Ferretti measure of financial integration was employed the impact of the trade openness channel was insignificant whilst a significant impact was found based on KAOPEN. The inconclusive findings for the trade openness channel may indicate the impact of financial integration on economic growth depends on the proxy of financial integration utilized. In addition, the study also gathered some interesting results where financial development, institutional quality, trade openness, and government size (government spending) are significant drivers of financial integration. The study makes some fundamental contributions to literature on financial integration, financial development, and economic growth. Initially, the study provides empirical evidence on the nature of the impact of financial integration on financial development in the SADC. In particular, this study contributes to the body of knowledge by showing that the impact of financial integration on financial development is linear. Secondly, this study makes an original contribution to the literature on the channels through which financial integration affect economic growth in the SADC, providing a more subtlety understanding of the mechanisms at play. Finally, the study provides important policy implications for policymakers and financial regulators in the SADC who seek to promote economic growth through financial integration. The findings of the study imply that deeper financial integration is crucial in the SADC region as it can potentially increase the rate of economic growth in the region. Not only economic growth will be boosted but also the institutional quality and the development of the financial sector of the countries in the region. Based on these findings, the study recommends that the governments of the member countries in the region continue to come up with policies that boost regional and international financial integration. The study suggests that to ensure that they continuously reap positive benefits from financial integration, member countries of the SADC should appoint a board that deals with implementation and accountability. This board must be responsible for ensuring that member countries implement the formulated policies and should also hold member countries accountable in case of failure to implement the formulated policies. Since the region is pursuing financial integration, the region must come up with policies that prioritize domestic developments in the form of financial development, improving domestic institutional quality and reducing trade restrictions in advance in order to ensure that preconditions for financial integration are met. Developing these will attract different forms of financial flows or increase financial openness which will ultimately boost economic growth. , Thesis (PhD) -- Faculty of Management and Commerce, 2023

  • Description: Medication adherence is a patient's active and voluntary participation in following all the recommendations and instructions agreed upon with a health care provider such as a pharmacist. Adherence is a multidimensional phenomenon determined by the interplay of five factors: patient-related factors, socioeconomic factors, condition-related factors, health system-related factors, and therapy-related factors. Medication non-adherence is a problem in many countries, especially low to middle-income countries, including South Africa (SA). In low to middle-income countries, non-adherence is often worse due to insufficient health resources and inequities in access to health care. Medication adherence is a global problem and has raised the need for research and review. Many healthcare professionals, especially pharmacists, have an essential role in promoting medication adherence. This study described, explained and evaluated the policies in SA relating to the pharmacist's role in promoting medication adherence. Furthermore, it described medication adherence-related education at four universities in South Africa. The study was qualitative, and a two-phased approach was employed. In the first phase, a document analysis of the pharmacist’s role in supporting medication adherence was conducted as described in national policies and guidelines in SA. A total of 38 documents were analysed, including critical documents such as the South African Pharmacy Council Good Pharmacy Practice Manual and Associated SAPC rules (GPP) manual, National Drug Policy (NDP), Standard treatment guidelines (STGS) and Integrated Adherence Guidelines. The READ approach was used in conducting the document analysis and involved (1) preparing materials, (2) extracting data, (3) analysing data, and (4) distilling findings. The critical roles of pharmacists in medication adherence that were identified were in drug use, supply and management, dispensing, therapeutic drug monitoring, pharmacovigilance, pharmaceutical care, and special programmes like antimicrobial stewardship (AMS), multi-drug resistant tuberculosis (MDR-TB) care and antiretroviral treatment (ARV) and chronic conditions. In the second phase, in-depth interviews were conducted with lecturers to investigate and report on the inclusion of medication adherence and the teaching thereof in the curriculum of the Bachelor of Pharmacy Degree (BPharm) in pharmacy institutions in SA. Purposive sampling was used, and seven lecturers from four different institutions participated in the interviews. The interviews were conducted via Zoom® and were transcribed and analysed using thematic analysis. The teaching of medication adherence in the BPharm curriculum of the respective interviewed pharmacy institutions was explored. It was found that the topic of medication adherence was integrated into all subjects throughout the curriculum and not taught as a formal course. Although medication adherence is taught in many disciplines, it is predominantly in pharmacy practice in all institutions. The teaching methods identified included lectures, case studies, workshops, tutorials, practicals, readings, tasks, assignments and videos. The perceived effectiveness of the teaching methods was explored; also the time spent teaching medication adherence and the time efficiency. Student understanding, interest and engagement with the topic were explored and determined through their assessment performance and class attendance. In conclusion, from policies, the pharmacist's role concerning adherence is indirectly integrated into many other roles. It is often not distinguishable from that of other healthcare professionals and is often implied as part of a more generic role. Pharmacy students are educated on medication adherence and the skills and knowledge required to identify, monitor and support patient adherence to therapy. However, there is scope to increase the course content on medication adherence. There is a need to identify effective strategies for preparing pharmacists to assist patients in medication adherence. , Thesis (MPharm) -- Faculty of Pharmacy, 2023
