- Description: There have been many initiatives that have been implemented to motivate women to enter and remain in the engineering field in South Africa and across the world. However, research has shown that the numbers of women representation in the engineering sector is still very low. It was the aim of this study to explore essential themes that can be adopted to improve career growth and retention of women in the engineering automotive industry sector of Gqeberha. The study further seeks to formulate a set of key organisational culture attributes that needs to be incorporated into organisations to improve female artisans’ career advancement and retention. The research took a positivist/postposivist paradigm, with a quantitative research approach using a probability sampling method. A structured self-administered questionnaire was distributed electronically to female respondents employed in the automotive companies located within Gqeberha with the aim of obtaining information to achieve the research objectives, targeting a population of female artisans employed in these organisations. Seventy-five (75) questionnaires were distributed, forty-one (41) were completed and returned, which represents a 54.67% response rate. The research found that there is a significant relationship between organisational culture, career advancement and employee retention. The main themes that emerged from the study of employee retention were sense of security, transparency and innovation. While training and development opportunities were found to be important for career advancement. Key recommendations from the research are that organisations must frequently conduct their own organisational culture surveys, short-incentive schemes for engineering managers and human resources managers be linked to gender diversity and provision of mentors for female artisans , Thesis (Ma) -- Faculty of Faculty of Business and Economic Sciences, 2023

- Description: The wineries of the Cape winelands are increasingly engaging in corporate social responsibility (CSR) and corporate citizenship (CC). Both these practices are widely viewed as having the potential to increase business success of these wineries. There is however a lack of research on the state of these practices in these wineries especially against the background of reports of exploitation of workers on winelands. The aim of this study is therefore to investigate the state of CSR and CC in the Cape winelands wineries and the impact that these practices have on the business success of these wineries. The study is located in the positivistic research tradition. The data was collected using a closed-ended questionnaire which was distributed to 100 employees (managers and general workers) in the wineries. The questionnaire items were anchored on a Likert-style (disagree to agree) answering scale. Pearson correlations and multiple regression coefficients, as well as descriptive statistics were used. Eventually only 42 respondents participated in the study. The empirical findings indicated that CSR (focusing on its economic, environmental, and social impacts) and CC were significantly positively related to the business success of the wineries in the Cape winelands. CC emerged as the strongest determinant of the business success of these wineries. The empirical results also revealed reasonable to high levels of CSR and CC prevalence in these wineries. Although limitations were experienced in the study, useful managerial recommendations emerged from it empirical results. The study therefore indicated some important areas for future research. , Thesis (Ma) -- Faculty of Faculty of Business and Economic Sciences, 2023

- Description: South Africa has low levels of financial literacy. This includes students, even though they are educated. The literature reveals South African students struggle to grasp personal finance concepts, specifically related to saving, monitoring debt and budgeting. It is well-known that financial education improves financial literacy, however, financial education is not implemented as a stand-alone subject for students at primary and high school level in the South African context. Financial education is only implemented into specific learning areas in the curricula such as Economic Management Sciences, Mathematical Literacy, Mathematics, Accounting, Business Studies and Economics. At university level, some students from specific faculties are exposed to a financial education module. A gap in the literature warranted a longitudinal investigation among students to discover the impact of university financial education on financial literacy. There is a lack of research to assess the financial literacy of students by measuring their financial knowledge and financial skills objectively. It is crucial to determine whether a relationship exists between financial education and financial literacy involving South African students. Hence, according to this, the primary objective of the study was to investigate the influence of financial education on financial literacy of Higher Certificate (Business Studies) students at Nelson Mandela University. The rationale behind choosing these students as a sample is because the programme comprises a Fundamentals of Personal Finance module which focused on day-to-day financial education. Two literature review chapters were conducted to accomplish the primary objective of the study. The first literature review focused on the nature and importance of financial education, core components of financial education, sources of financial education, personal finance module as well as the impact of financial education on financial literacy. This led to the second literature review, which examined the exposure of financial education on financial literacy levels. In addition, financial literacy components and the relationship between financial education on financial literacy were discussed. Thereafter, the hypotheses of the study were developed to empirically test the sample on their financial literacy levels before and after exposure to financial vi education by measuring financial knowledge, financial skills, financial attitude and financial behaviour. An online questionnaire was used to collect data from the respondents before exposure to the Fundamentals of Finance module to determine their financial literacy levels. The same questionnaire was completed by the respondents to discover whether financial literacy levels stayed the same, declined or improved after exposure to financial education. Through convenience and criterion sampling, 233 usable questionnaires were collected before exposure to financial education which translated into an effective rate of 64.54 percent. Following this, 77 usable questionnaires were collected after financial education exposure which was interpreted as an effective rate of 61.60 percent. The low response rate was due to the level of computer literacy amongst the respondents, some respondents may have not had access to a laptop, computer desktop or mobile device, and the respondents were busy preparing for examinations. The empirical data was analysed through STATISTICA by performing Confirmatory Factor Analysis (CFA) tests, reliability tests (Cronbach Alpha), descriptive statistics related to the demographics of the respondents, mean scores and standard deviations. Further statistical analyses were conducted through Pearson’s Product Moment Correlation Coefficient tests to determine the nature of the relationships between financial knowledge, financial skills, financial attitude and financial behaviour. Paired t-tests were conducted to discover the differences in the mean scores in the financial literacy levels of respondents before and after exposure to financial education. The empirical results revealed significant relationships between financial education and financial knowledge; financial education and financial skills; financial education and financial attitude; financial education and financial behaviour. This led to all four hypotheses of the study being accepted. The financial knowledge, financial skills and financial attitude of Higher Certificate (Business Studies) students did not improve after completing the Fundamentals of Personal Finance module. Only the financial behaviour of these students improved after financial education exposure. The results of the study provided the basis for the development of recommendations to improve financial literacy levels by providing financial education content that is suitable for individuals in different stages of their lives. , Thesis (MA) -- Faculty of Faculty of Business and Economic Sciences, 2023

- Description: The aim of the public sector is to deliver effective and efficient services whilst reducing these delivery costs (Price Waterhouse Coopers, 2007). In addressing this aim of public service delivery, the objective of the study was to investigate the impact of leadership on service delivery in a specific public sector. The researcher utilised a non-experimental correlation research design where the participants were entry level officials from region six within the National Department of Employment and Labour in the Eastern Cape, who reported to the first level of management (supervisors/team leaders). A probability sampling design with a cluster sampling method was used, wherein the population was grouped and a cluster was chosen. The sample consisted of officials who delivered services to the public at an entry administrative level either in a direct role or a supporting role. These officials reported to the first line of leadership in the hierarchy (supervisors/team leaders). Questionnaires were used as the primary source of data collection to solicit data from participants and obtain feedback on leadership behaviour on operational and service delivery issues in the workplace. The data was processed by statistical calculations of the mean, median, mode and standard deviation. The Cronbach Alpha as a test of internal validity, was used to test for reliability and validity. The findings of the study revealed that the department strived to improve leadership and service delivery in rendering public service which will naturally contribute to the 2030 vision of the National Development Plan and the fulfilment of the organisational mandate (South Africa National Planning Commission, 2012). , Thesis (MA) -- Faculty of Faculty of Business and Economic Sciences, 2023

- Description: The intensive nature of plantation forestry in South Africa requires efficiency and financial viability in production systems, amidst a complex growing environment subjected to changing macro-climatic patterns. The success of plantation forestry operations depends, amongst others, on our understanding of tree growth and wood formation patterns in response to variable growing conditions in both space and time. This study was conducted on the two most commonly used species in the southern and Eastern Cape forestry regions, i.e., Pinus radiata and P. elliottii. The region is regarded as highly suitable for plantation forestry in terms of climatic conditions, but soil characteristics pose several challenges due to nutritional disorders and poor drainage. The study focused on investigating the influence of both soil and climatic conditions on the growth and Wood Density properties of the two species, and to establish functional relationships where possible. The two species showed comparable growth rates at the reference age of 13 years on the range of sites sampled in the study area. An analysis of variance showed greater differences in Site Index between than within sample plots, pointing towards the possible influence of site on growth variation. Correlations between climatic variables and the growth of both species were generally weak and contradictory. Possible reasons for this phenomenon are discussed. It is proposed that the general favourable climatic profile of the region and hydromorphic nature of soils reduce the chances of significant correlations between variables influencing moisture availability and tree growth. The analysis of correlations between soil parameters and tree growth revealed some influence of soil organic C and Na on the growth of P. elliottii. This is discussed in terms of our understanding of the influence of soil parent material and soil ecology. The absence of any correlations between soil chemical parameters and the growth of P. radiata was conspicuous. This is in contradiction with earlier studies on the species in the region and can possibly be explained in terms of the site-specific fertilizing policy of the industry, as well as the less diverse range of sites sampled than in the past, which can mask or reduce nutrient limitations for tree growth. However, P. radiata did show a high level of sensitivity towards effective soil depth. Site-quality prediction models are proposed for the two species, but with variable application value due to the limited options of significant control variables that can be considered for inclusion in the models. , Thesis (MSc) -- Faculty of Science, School of Natural Resource Science and Management, 2023

- Description: The global impact of family businesses is increasing in a significant manner. The importance of family businesses has been recognised by academic institutions through the establishment of family business research centres and academic programmes for family businesses, as well as practitioner-oriented journals in family business studies. In most developed and developing market economies, family businesses have been projected as one of the primary forms of private enterprise that play an important role in both national and global economies, including South Africa. In other words, in the global innovation context, family businesses are considered to be the backbone of economic development. Given the importance of innovation to family businesses in contributing to economic growth and sustainability across generations, as well as the limited research that has been conducted on South African family businesses and innovation, the primary objective of this research was to investigate the relationship of selected drivers of innovation and Innovation outputs in South-African family businesses, as well as how the family, through its Socioemotional wealth, moderates the relationships between the drivers of innovation and Innovation outputs. This study uses the socioemotional wealth (SEW) and the resource-based theory (RBV) as the basis of its theoretical orientation. The following drivers of innovation were identified during the literature review (independent variable), namely: Financial capital, Human capital and leadership, Social capital, Learning orientation, Entrepreneurial orientation, Market orientation, Organisational culture, and Knowledge management as having an impact on Innovation outputs (dependent variable). In addition, Socioemotional wealth (SEW) was hypothesised as having a moderating influence on the relationships between the drivers of innovation and Innovation ouptuts. Four demographic variables (Size of the business, Age of the business, Generation of the family and Industry of operation) were identified as having a potential influence on the hypothesised relationships. Each of the constructs were clearly defined and then operationalised. Operationalisation was done by using reliable and valid items sourced from tested vii measuring instruments used in previous studies, as well as a number of self-generated items based on secondary sources. A structured questionnaire was made available online to respondents identified by means of the convenience snowball sampling technique, and data was collected from 331 family businesses in South Africa. The usable questionnaires were subjected to various data analyses techniques. Confirmatory Factor Analyses (CFA) were performed on each factor that confirms the factor structures by using various goodness-of-fit indices. Subsequent to the CFAs, the validity and reliability of the measuring instrument was assessed. As a result of these analyses, three new independent variables emerged as drivers of Innovation outputs in South African family businesses, namely: Funding of research and innovation, Financial, human and social capital resources, and Shared business vision, resources information and knowledge. In addition the SEW construct revealed two dimensions as dependant variables, namely: Family influence, control and commitment and Business reputation and commitment. The reliability of the measuring instrument was evaluated using Cronbach’s alpha coefficients, while the assessment of validity involved calculations of the average variance extracted (AVE) estimates and squared correlations between constructs. Structural Equation Modelling (SEM) was the main statistical procedure used to test the significance of the relationships hypothesised between the various independent, moderating and dependent variables. The main finding of the study reveals that there is a significant positive relationship between Financial, human and social capital resources, and Innovation outputs. There is also a significant positive relationship between Shared business vision, resources, information and knowledge and Innovation outputs. Furthermore, Family influence, control and commitment positively moderates the relationship between Shared business vision, resources, information and knowledge and Innovation outputs. while Business reputation and succession positively moderates the relationship between Financial, human, social capital resources, and Innovation outputs. Finally, Business reputation and succession positively moderates the relationship between Shared business vision, resources, information and knowledge viii and Innovation outputs. Concerning the selected demographic variables, this study found that Age of the business has a significant influence on Innovation outputs. This study makes several theoretical and practical contributions. This study is the first of its kind that investigates the relationship between the drivers of innovation and Innovation outputs of South African family businesses. Second, this study is the first to investigate how the family, through its Socioemotional wealth, moderates the relationships between the drivers of innovation and Innovation outputs of South African family businesses. Having a better understanding of how and when the family system impacts the innovation decisions in the family business is important because it helps researchers understand the differences between family businesses (i.e. family firm heterogeneity) and non-family businesses. Third, the findings indicated that the adaptation of the SEW and RBV theories was accurate in understanding how the family, through its socioemotional wealth, influences innovation decisions. Fourth, concerning the selected demographic variables, this study found that Age of the business has a significant influence on Innovation outputs. This finding is another valuable contribution to the literature on innovation, given the inconsistent and sometimes inconclusive findings concerning the relationship between age of the business and innovation activities. The study's final theoretical contribution is the development of a measurement tool that accurately assesses the drivers of innovation and innovation outputs and the influence of the five dimensions of socioemotional wealth. Other family business researchers, business mentors and or family business owners themselves can use this measurement tool to assess and monitor factors that have an impact on innovation activities inside their businesses. Practically, this study makes several suggestions on how family business owners and managers could improve the Innovation outputs of their businesses and become aware of how the family could influence the innovation choices and decisions made in the business. , Thesis (PhD) -- Faculty of Faculty of Business and Economic Sciences, 2023

The following drivers of innovation were identified during the literature review (independent variable), namely: Financial capital, Human capital and leadership, Social capital, Learning orientation, Entrepreneurial orientation, Market orientation, Organisational culture, and Knowledge management as having an impact on Innovation outputs (dependent variable). In addition, Socioemotional wealth (SEW) was hypothesised as having a moderating influence on the relationships between the drivers of innovation and Innovation ouptuts. Four demographic variables (Size of the business, Age of the business, Generation of the family and Industry of operation) were identified as having a potential influence on the hypothesised relationships. Each of the constructs were clearly defined and then operationalised. Operationalisation was done by using reliable and valid items sourced from tested vii measuring instruments used in previous studies, as well as a number of self-generated items based on secondary sources. A structured questionnaire was made available online to respondents identified by means of the convenience snowball sampling technique, and data was collected from 331 family businesses in South Africa. The usable questionnaires were subjected to various data analyses techniques. Confirmatory Factor Analyses (CFA) were performed on each factor that confirms the factor structures by using various goodness-of-fit indices. Subsequent to the CFAs, the validity and reliability of the measuring instrument was assessed. As a result of these analyses, three new independent variables emerged as drivers of Innovation outputs in South African family businesses, namely: Funding of research and innovation, Financial, human and social capital resources, and Shared business vision, resources information and knowledge. In addition the SEW construct revealed two dimensions as dependant variables, namely: Family influence, control and commitment and Business reputation and commitment. The reliability of the measuring instrument was evaluated using Cronbach’s alpha coefficients, while the assessment of validity involved calculations of the average variance extracted (AVE) estimates and squared correlations between constructs. Structural Equation Modelling (SEM) was the main statistical procedure used to test the significance of the relationships hypothesised between the various independent, moderating and dependent variables. The main finding of the study reveals that there is a significant positive relationship between Financial, human and social capital resources, and Innovation outputs. There is also a significant positive relationship between Shared business vision, resources, information and knowledge and Innovation outputs. Furthermore, Family influence, control and commitment positively moderates the relationship between Shared business vision, resources, information and knowledge and Innovation outputs. while Business reputation and succession positively moderates the relationship between Financial, human, social capital resources, and Innovation outputs. Finally, Business reputation and succession positively moderates the relationship between Shared business vision, resources, information and knowledge viii and Innovation outputs. Concerning the selected demographic variables, this study found that Age of the business has a significant influence on Innovation outputs. This study makes several theoretical and practical contributions. This study is the first of its kind that investigates the relationship between the drivers of innovation and Innovation outputs of South African family businesses. Second, this study is the first to investigate how the family, through its Socioemotional wealth, moderates the relationships between the drivers of innovation and Innovation outputs of South African family businesses. Having a better understanding of how and when the family system impacts the innovation decisions in the family business is important because it helps researchers understand the differences between family businesses (i.e. family firm heterogeneity) and non-family businesses. Third, the findings indicated that the adaptation of the SEW and RBV theories was accurate in understanding how the family, through its socioemotional wealth, influences innovation decisions. Fourth, concerning the selected demographic variables, this study found that Age of the business has a significant influence on Innovation outputs. This finding is another valuable contribution to the literature on innovation, given the inconsistent and sometimes inconclusive findings concerning the relationship between age of the business and innovation activities. The study's final theoretical contribution is the development of a measurement tool that accurately assesses the drivers of innovation and innovation outputs and the influence of the five dimensions of socioemotional wealth. Other family business researchers, business mentors and or family business owners themselves can use this measurement tool to assess and monitor factors that have an impact on innovation activities inside their businesses. Practically, this study makes several suggestions on how family business owners and managers could improve the Innovation outputs of their businesses and become aware of how the family could influence the innovation choices and decisions made in the business. , Thesis (PhD) -- Faculty of Faculty of Business and Economic Sciences, 2023

- Description: The introduction of Self-Service Checkout Systems (SSCOs) has disrupted and continues to transform grocery retail businesses particularly in the age of the 4th Industrial Revolution (4IR), which is characterised by the pervasive presence of technological innovation in multiple sectors. SSCOs have over the years made significant in-roads in the grocery retail sector, particularly in the developed world with few exceptions of implementation in the developing world. Self Service Technologies (SST) have been used across various industries for many years in order to improve customer experience, or to address business priorities, or both. SSCOs (an SST technology) within grocery retail, have been purported to increase customer convenience, efficiency and bolster the competitive advantage of various businesses, amongst other benefits. The benefits and opportunities, risk and challenges, impact on business, perceptions of customers and customer acceptance of SSCOs have been and continue to be widely studied within the retail sector of the developed and in some parts of the developing world. The understanding and implementation of SSCOs in developing countries in general and South Africa in particular are at an embryonic stage. Questions of implementation, acceptance and adoption of SSCOs in South Africa are under-researched and nascent. However, despite their vagueness within the South African grocery retail sector, there are instances where SSCOs have been implemented in South Africa. Taking into account the fact that the South African grocery retail sector is heavily influenced by the adoption of technological innovation and follows the trends from the developed world, it is only a matter of time before SSCOs become mainstream technologies in South Africa. This is more so particularly in the era of the 4IR where technology is increasingly transforming entire industries. Against this backdrop, this study addresses the question of acceptance of SSCOs within the grocery retail sector in South Africa. Whilst grocery retailers consider whether to implement SSCOs, they have to ask themselves a number of pertinent questions, not in the least whether customers would be willing to adopt the use of the technology. It is in light of this acceptability of SSCOs that the research engaged grocery retailers to investigate their perception regarding the factors that affect the acceptance of SSCOs within the South African grocery retail sector. This study followed a qualitative research design. Participants were management and owners of the SPAR retail group in South Africa. Twenty-three participants took part in the study and seventeen participant’s responses were accepted for analysis. An online open ended vi | P a g e questionnaire was used to collect data from participants and a thematic analysis was applied to the collected data in order to search for themes within the data. The Technology Acceptance Model (TAM) and the Theory of Diffusion of Innovation (DOI) were used as frameworks to interpret the study findings. The results of the study indicate that the South African grocery retail sector is innovative and implements various technologies. Further, a number of grocery retailers are actively considering the implementation of SSCOs. A number of factors that promote that acceptance of SSCOs were identified by the study, for example, customer experience at checkout, which includes convenience and efficiency and business profitability. On the other hand, there are factors that hinder the acceptance of SSCOs, which include factors like loss of employment, poor infrastructure and the cost of implementation amongst others. Based on the results of the study a theoretical framework was developed, which was used to give recommendations to the grocery retail sector in order to offer guidance regarding the implementation of SSCOs in South Africa. Finally, areas and orientations of future research were identified. This study contributes to the literature on SSCOs in South Africa in particular and the developing world in general. In addition, this study contributes to academic theory and business practise by applying the Diffusion of Innovation Theory and the Technology Acceptance Model to a unique context in a new way, i.e. SSCOs in the grocery retail sector in South Africa. The limitation of the study is that the participants were from one grocery retail organisation and thus probably represent a certain grocery retail outlook based on the culture of the organisation. Future research would need to be more inclusive and have a heterogeneous research sample in order to be more reflective of multiple organisations and cultures within the grocery retail sector in South Africa. The introduction of SSCOs in South Africa will transform the grocery retail sector. The understanding of the technology and its acceptance within the sector is critical to help grocery retailers develop strategies to drive business growth, improve customer experience and capitalise on the direction of transformation that technology brings to the sector. , Thesis (MA) -- Faculty of Faculty of Business and Economic Sciences, 2023

- Description: The use of biomass as an alternate source of energy has grown in popularity. Different types of biomass are obtained from a variety of sources including natural forests, forestry plantations and agriculture residues. However, forestry residues have been identified as the most promising source, due to the wide variety of plant products including leaves, twigs, branches, merchantable stem, stumps and roots. The main sources of plantation forest biomass are residues from thinning, clearfell and conventional products such as pulpwood and sawn timber operations. These residues can accumulate between 4.3 to 9.4 billion tonnes annually around the world. The biomass availability in plantation forests has led to the development of different harvesting systems to help collect the products from infield to sawmill. Biomass harvesting has mainly been achieved through mechanised systems because of their high yields. However, the use of manual systems has been neglected due to technical limitations and financial viability. Thus, in South Africa, there is no scientific research looking at manual systems of collecting biomass from plantations. Because of this, different forestry stakeholders, including small growers and contractors using manual systems for biomass harvesting have limited knowledge regarding what to expect in terms of recoverable amounts, productivity and cost. This research examines the productivity of the manual biomass collection and the quantification of recovered and unrecovered residues after mechanised full tree (FT) and semi mechanised tree length (TL) harvesting operations in Pinus patula compartments. A total number of 8 plots with +/-200 standing trees were marked in each system. The diameter and height of all marked trees were measured to determine tree volume. Moreover, the quantification of recoverable woody biomass was determined, where after, a residues assessment method using plots and line transects was used to determine the amount of unrecovered residues. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2023

- Description: Organisations of the 21st century face a plethora of changes due to globalisation, a world referred to as volatile, uncertain, complex and ambiguous (VUCA). Organisations must consider pertinent stakeholders, specifically employees, and by representation, trade unions, during organisational change attempts. The study has explored the role of trade unions during organisational change in South African organisations. A literature review was conducted, which explored, amongst others, factors driving change, organisational change management models, the labour relations landscape in South Africa and the role of trade unions in organisational change. The empirical study included semi-structured interviews and a survey with a questionnaire. An exploratory sequential mixed methods research design was followed, with semi-structured interviews conducted with trade union representatives and human resource/employment relations managers. Thereafter, an online self-administered survey was conducted focusing on employees. A non-probability judgement design was employed in sampling the participants for the qualitative approach, and five (N = 5) HR/employment relations managers and six (N = 6) trade union representatives were interviewed. Random sampling was employed for the quantitative component and 74 questionnaires were completed. The interviews were thematically analysed while for the survey, exploratory factor and correlation analysis were used. The factor analysis extracted three factors: Before Change; During Change; and After Change. Based on the results recommendations for senior management, HR/ER managers; and for trade unions were presented. The recommendations include that organisations use the framework as a guide to involve trade unions. Trade unions and their representatives need to be acknowledged as important stakeholders before change is introduced. Knowledge of labour law is essential and a culture of open communication must be evident before, during and after change. Trade unions should organise conferences (Indabas) to reorientate and reskill themselves about their role during organisational change within South African organisations. The main contribution of the study is that HR/ER managers and trade union representatives should utilise the framework developed in this study to advance best practices in respect of the role of trade unions in organisational change in the South African context. , Thesis (Ma) --Faculty of Faculty of Business and Economic Sciences, 2023

- Description: Land is the most valuable resource in every nation since it supports all aspects of life by giving people food, shelter, and water. In South Africa, the legacy of the colonial past remains with ongoing poverty, landlessness, inequality, and insecurity to this day. Large tracts of property are still owned by the minority who benefited from apartheid colonialism, the land issue continues to be a major concern in South African politics. After 1994 the Department of Land Affairs released a White Paper on Land Reform that served as the model for many subsequent land reform initiatives, including land restitution. Former Bantustans contain a sizable quantity of unsurveyed land that is kept in trust and administered by traditional leaders who serve as custodians. In order to return the land to its rightful owners through land restitution as well as other land reform initiatives, the government established a legal organization, the Communal Property Association (CPA), against which the land could be registered. This study focuses on CPAs located on unsurveyed communal land in the Eastern Cape Province's OR Tambo District. There has been discussion in parliament and among academics about the effectiveness of CPAs in addressing socioeconomic needs. Various studies and departmental assessments have revealed that CPAs are not in compliance with the Act that governs them, and the Department of Agriculture, Rural Development, and Land Reform developed a regularization intervention strategy to close administrative gaps in slow land transfer, membership, financial reporting, asset management, and accountability. This study investigates whether CPAs provide socioeconomic benefits, and assesses their current practicability. Five CPAs were sampled, each located in different towns in the OR Tambo District of the Eastern Cape. The findings are that while there has been a socio-economic impact in the broader community where CPAs are located there has been limited benefit to intended beneficiaries. CPAs and their administration are in dire need of change. Too large CPA groupings, a lack of understanding of the constitution, a lack of business skills, a lack of asset management, corrupt transactions on CPA land, traditional leadership interference, delays in land surveying and transfer, a lack of government support, and land invasions are all challenges. The government needs to prioritize land surveying and transfer to beneficiaries in order to reduce land invasions and conflicts with traditional leaders. , Thesis (MA) -- Faculty of Faculty of Business and Economic Sciences, 2023

- Description: Salt marshes are one of the most productive ecosystems globally. These ‘blue carbon’ habitats are in many respects resilient to climate change effects, able to track sea level rise and act as carbon sinks. Since salt marshes are economically and ecologically essential habitats (for example providing foraging grounds for invertebrates, fish, birds and humans), understanding the processes that control their structure is crucial to best maintain ecosystem services provided by these habitats. For decades the importance of top-down forces, such as grazing, has not been recognised as being important in controlling salt marsh plant productivity. Rather, bottom-up forces, such as the availability of oxygen, was thought to be the main constraint to primary production. Therefore, a better understanding of salt marsh ecosystem dynamics and whether grazer control exists is needed. Although grazer top-down control has been demonstrated in salt marshes in locations such as the United States, this has not been investigated in South Africa. This is a crucial knowledge gap locally considering the importance of salt marsh ecosystems. The aim of this study was therefore to determine what role consumers play in structuring South Africa’s estuarine salt marsh vegetation, thereby also contextualising this process internationally. In order to achieve this, the abundance of grapsoid crabs was estimated and related to key salt marsh features, such as Spartina maritima stem height and stem density, which was quantified from observational surveys. Sampling took place at the beginning and end of the early-spring and late-summer growth period (September 2021 and April 2022) in the Knysna, Kromme and Swartkops estuaries. If a correlation was observed between crab density and salt marsh features, it was important to determine whether they consume the salt marsh vegetation or if the effect was due to their burrowing activities. Hence, the diet of grapsoid crabs was investigated using stable isotope and gut content analysis. To examine the importance of crab grazing in controlling the growth of salt marsh vegetation, crab abundance was manipulated in situ by means of exclusion cages. This experiment ran for five months in the Kromme Estuary, from November 2021 to March 2022 over the salt marsh growing season. An ex situ feeding experiment was also conducted on 30 crab specimens collected from the Kromme Estuary, during May 2022. These crabs were starved for 48 hours and thereafter fed different components of Spartina (growing and dead blades, and roots and rhizomes).

- Description: Salt marshes are one of the most productive ecosystems globally. These ‘blue carbon’ habitats are in many respects resilient to climate change effects, able to track sea level rise and act as carbon sinks. Since salt marshes are economically and ecologically essential habitats (for example providing foraging grounds for invertebrates, fish, birds and humans), understanding the processes that control their structure is crucial to best maintain ecosystem services provided by these habitats. For decades the importance of top-down forces, such as grazing, has not been recognised as being important in controlling salt marsh plant productivity. Rather, bottom-up forces, such as the availability of oxygen, was thought to be the main constraint to primary production. Therefore, a better understanding of salt marsh ecosystem dynamics and whether grazer control exists is needed. Although grazer top-down control has been demonstrated in salt marshes in locations such as the United States, this has not been investigated in South Africa. This is a crucial knowledge gap locally considering the importance of salt marsh ecosystems. The aim of this study was therefore to determine what role consumers play in structuring South Africa’s estuarine salt marsh vegetation, thereby also contextualising this process internationally. In order to achieve this, the abundance of grapsoid crabs was estimated and related to key salt marsh features, such as Spartina maritima stem height and stem density, which was quantified from observational surveys. Sampling took place at the beginning and end of the early-spring and late-summer growth period (September 2021 and April 2022) in the Knysna, Kromme and Swartkops estuaries. If a correlation was observed between crab density and salt marsh features, it was important to determine whether they consume the salt marsh vegetation or if the effect was due to their burrowing activities. Hence, the diet of grapsoid crabs was investigated using stable isotope and gut content analysis. To examine the importance of crab grazing in controlling the growth of salt marsh vegetation, crab abundance was manipulated in situ by means of exclusion cages. This experiment ran for five months in the Kromme Estuary, from November 2021 to March 2022 over the salt marsh growing season. An ex situ feeding experiment was also conducted on 30 crab specimens collected from the Kromme Estuary, during May 2022. These crabs were starved for 48 hours and thereafter fed different components of Spartina (growing and dead blades, and roots and rhizomes). The food consumed was quantified as the change in plant length and dry weight after 48 hours, which gave a maximum grazing rate for the different food sources. It was found that crabs are having a minimal impact on the salt marsh vegetation structure. Spartina maritima does form an important component of the diet of grapsoid crabs, however, this is not their only source of food, and possibly not their preferred source of food. They are however contributing to sediment properties through their burrowing activities. The iii ex situ feeding experiment showed that grapsoid crabs can consume all vegetative components of Spartina, with a significantly greater amount of roots and rhizomes consumed. There was no consistent effect in terms of the exclusion of grazers, indicating that other mitigating factors could be reducing the impacts of grapsoid exclusion in situ. Together, these findings contribute knowledge that can be used to inform conservation by quantifying what the salt marsh risks losing in the absence or overabundance of crabs, as has occurred elsewhere globally.

- Description: The study sought to explore township economic performance and contribution towards economic development in Nelson Mandela Bay, using the circular flow of money model. The study surveyed households and businesses in one of the townships in Nelson Mandela Bay (Kwazakhele). The survey reached out to 100 households and 100 businesses, totalling 200 participants. Data were analysed using descriptive and inferential statistics. The current state of the township economy is not a desirable one. There are more leakages than injections into the township economy. More township residents (especially high-income earners) choose to shop outside the township for goods because the township does not have the goods that residents need. Key findings show that township businesses are small in nature, primarily sole propriety and operate informally in the streets. Most people who work, earn R3500 and below and spend most of their income on food and groceries. Supply for the most consumed products in the township comes mainly from outside the township, and there is no circular flow in the township economy. However, there are more people working inside the township than those who work outside the township. More essential goods are found in the township than before, so residents do not have to travel outside the township to get basic groceries and food. Other findings show that the government is not intervening enough to help the township businesses through policy implementation and financial aid. Businesses in the township do not pay taxes, and this can limit what the government can do to help them. There are other business constraints that are prohibiting the township businesses to reach the optimum level, and the top cited constraint is Crime. The study recommended that government should intervene by passing a bill like the Gauteng Township Economy Bill that aims at assisting township businesses. Households should come up with other streams of income through entrepreneurship so that they can not only depend on government social grants for income. Businesses should form bulk buying groups to increase buying power to be competitive. Lastly, businesses should seek alternative sources of power because electricity is expensive, and the load-shedding is prohibiting township businesses from running efficiently. , Thesis (MA) -- Faculty of Faculty of Business and Economic Sciences, 2023

- Description: The importance of technological innovation transfer to a country’s socio-economic development cannot be underestimated. This is because technological innovation provides the base for today’s knowledge-based economy. As a developing economy, Ghana faces several socio-economic development challenges as those of other developing economies. Despite these socio-economic challenges, it has been shown that thriving Small and Medium Size Enterprises (SMEs) in Ghana, could help improve the socio-economic development of the Ghanaian economy. Notwithstanding the valuable contributions of SMEs to socio-economic development in Ghana, there appears to be a more significant disconnect between research outcomes from research institutions to SMEs in the areas of technological innovation transfer. It appears there is no bridge between research institutions and SMEs. Against this backdrop, the study aimed at investigating how the transfer of technological innovation from research institutions to SMEs could enable SMEs to thrive and improve the socio-economic development of the Ghanaian economy. A mixed methods research approach was used for the study. The study applied a stratified sampling technique to select 432 CEOs of SMEs from a total population of 481CEOs which represents all CEOs of SMEs in the Association of Ghana Industries (AGI) database in Accra, Ghana as of December 2018. A purposive sampling technique was also used to select ten (10) directors of research institutions from a total number of nineteen (19) research institutions, (including the CSIRs and public tertiary educational institutions), based in Accra, Ghana. The study site, Accra, Ghana, was chosen because of its thriving SME populations and world-class research institutions. While a probit regression model was used to address only the objective three (3) of the research objectives, a descriptive statistical analysis was used via the usage of the SPSS software to generate the mean, standard deviation and percentages on the trend and distribution of the study variables among the study population. However, thematic analysis which enables the examination of the data to identify common themes was used on the qualitative data. The empirical results from the study indicated that technological innovation received from research institutions did not address SMEs' needs and did not result in products and services needed by the Ghanaian community. The study found low collaboration between research institutions and SMEs; and indicated that policy direction towards research institutions and SMEs' collaboration was the essential factor in boosting the efforts to drive collaborations. The study has made a valuable contribution to knowledge by showcasing a framework for successfully transferring technological innovation from research institutions to iii SMEs. The study also contributes to the Helix and triple helix models of innovation by indicating that the successful transfer of technological innovation goes beyond the production of basic research by research institutions and the adoption of basic research by SMEs. Thus, successful technological innovation transfer hinges mainly on effective collaboration between the parties involved. In this regard, the study also contributes to theory, as it is one of the first studies to directly address the problem concerning how the transfer of technological innovation from research institutions to SMEs could enable SMEs thrive and improve the socio-economic development of the Ghanaian economy. The study could enable policymakers/governments to understand the existing gap between research institutions and SMEs and how they can work together to harness technological innovation for the betterment of socio-economic development in Ghana. It also generates new empirical knowledge on research and SMEs. The new knowledge in technological innovations could shape theory and policy decision-making, resulting in enhanced sustainable socio-economic development in Ghana. , Thesis (PhD) -- Faculty of Business and Economic Sciences, 2023

- Description: This study investigates the role of Forte FM, Mdantsane FM and Rhodes Music Community Radios in disseminating the different kinds of messages on the nexus between the impacts of climate change and food security in the Eastern Cape Province, South Africa. Therefore, the study aims to investigate how these community radio stations play their informative, educative and entertainment roles regarding climate change and food security awareness programmes to their listeners. The study employed the qualitative research approach and convenience, and non-probability samplings techniques were subsequently used to select samples for this study. In-depth interviews were conducted individually for Forte FM, Mdantsane FM and Rhodes Music community radio programme managers respectively, who serve as the key informants. One focus group discussion each was held with residents of Golf Course, Mdantsane and Grahamstown areas where these radio stations broadcast from, with eight participants in each focus group. The total number of participants for the focus group discussions was 24 participants. The collected data were coded into themes using NVivo 12 software to generate the theme nodes and case nodes as key findings, analysis and then interpreted. The findings of this study confirmed that these three community radio stations do contribute to climate change communication through their programmes that focus on climate change and food security related issues. Another vital finding from the study showed that listeners do benefit immensely from these climate change and food security related programmes of the under-study community radio stations. Hence, listeners physical, social, and cognitive well-being of their climatic environment have been greatly impacted. In the same vein, the findings of this study further revealed that the rural communities who are mostly affected by the impacts of climate change on food security have been well informed and enlightened on the suitable ways to enhance a sustainable food security and climate adaptation system through Forte FM, Mdantsane FM, and Rhodes Music community radio stations. Significantly, this study has been able to come up with two suggested models and the conceptual frameworks, which are the Local Action Adaptive Communication (LAAC) Model and the Indigenous Behavioral Change Conceptual (IBCC) Model. These models are focused on increasing listeners interests, adaptation, and behavioral change on climate change issues. The models are also aimed at ensuring better climate change and food security communication Author. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2023

- Description: Tenofovir disoproxil fumarate (TDF) is a prescription drug used to treat and prevent human immunodeficiency virus (HIV) infections. It aids in the reduction of HIV in the body, allowing the immune system to function more effectively. This reduces the risk of HIV complications, such as infections, whilst improving the quality of life. TDF belongs to the nucleotide reverse transcriptase inhibitors category of drugs. These drugs limit the ability of the reverse transcriptase, an enzyme essential for each virus to replicate itself. A reduction in the cost of HIV treatment could improve supply security and make it more accessible to patients in need. Thus, this project aims to use flow technology to achieve a guaranteed supply chain and access. In this thesis, a method for the synthesis of TDF was developed using microreactors starting from the readily available adenine. The method was adapted from the traditional batch synthesis as currently there is no literature on the synthesis of TDF in flow chemistry. The batch methods used for the synthesis of the working standards were successfully translated to flow systems. For the best results to be obtained, optimisation of the reaction temperature, reagent molar equivalents and concentration was critical. From the optimisation studies, an improvement in conversion is evident throughout all stages. The flow synthesis of the first intermediate resulted in a conversion of 100 % in N,N-dimethylformamide in 6 min residence time. This study was conducted at 200 °C, which is higher than the boiling point of the solvent with the aid of a back pressure regulator. A key reagent in the synthesis of tenofovir, namely ((tosyloxy)methyl)phosphonic acid, had to be synthesised and it was successfully produced in 96 % yield. The second intermediate was synthesised through a successful coupling reaction between (R)-9-(2-hydroxypropyl)adenine and ((tosyloxy)methyl)- phosphonic acid, which afforded a 100 % conversion of tenofovir in 20 min total residence time. The multistep synthesis of tenofovir was a success as it afforded a 65 % overall conversion. The prodrug TDF was successfully synthesised at 120 °C with a 30 min residence time, yielding a conversion of 100 %. ii | P a g e This thesis consists of four chapters. Chapter one describes the background on HIV and a literature review on HIV drugs. This chapter also demonstrates flow chemistry and microreactors in detail and different routes for the synthesis of TDF in traditional batch methods. Chapter two provides a detailed methodology for batch synthesis and flow synthesis with analytical data. 1H-NMR, 13C-NMR and FTIR spectroscopy was used to evaluate all the compounds synthesised in this chapter. Chapter three thoroughly discusses the results that were obtained graphically, showing that the flow synthesis gives better yields than batch synthesis. In chapter 4, the conclusion of the whole investigation is stated along with the future work for the preparation of TDF. , Thesis (PhD) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2023

- Description: In-hospital mortality prediction remains an important task in Intensive Care Units (ICUs). In particular, the estimated in-hospital mortality risk is essential to describe case-mix, for research and clinical auditing purposes. Furthermore, in settings with limited hospital resources (e.g beds) such as the South African public health care system, the estimated in-hospital mortality risk is essential for resource allocation and to inform local patient triage guidelines. Commonly used models for prediction of in-hospital mortality in ICU patients includes, but not limited to, the Simplified Acute Physiology Score III (SAPS III). The SAPS III model was developed in 2005. Notably, the SAPS III model was developed without data collected from African based hospitals. Given the general application of the SAPS III model, including benchmarking and quality control, the development of such a model based on local data is of paramount importance. To this end, this study developed a model for prediction of in-hospital mortality based on data collected in a hospital in South Africa. Logistic regression modelling was used to develop the proposed mortality risk assessment model. The results indicated that the proposed model exhibited superior discrimination and classification abilities compared to the SAPS III model. Future research includes the external validation of the proposed model in different hospitals in South Africa. , Thesis (PhD) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2023

- Description: Generally, rural areas continue to experience high poverty levels and low incomes, which seem to be occasioned by high unemployment rates, limited educational attainments, and devastating floods and droughts. This situation is further exacerbated by increase in crime rates, making livelihoods even more difficult. To mitigate such adverse situations, rural households employ diverse strategies, including maintaining community gardens, one-home-one-garden schemes, as well as livestock and poultry production. The most prevalent livelihood strategy in South Africa or KwaZulu-Natal is broiler production, since it needs less space and a short production cycle compared to other livestock or crop enterprises. At the same time, income is generated over a short period. Besides, the government of KwaZulu Natal has actively intervened in the sector as part of its broader poverty reduction strategy and farmer support programmes. In KwaZulu-Natal Province, the provincial government has been supporting broiler producers for many years. While substantial research work has been done in the province on livelihood strategies, including livestock production on a province-wide basis, there is no information about how successful the broiler production funded by the government has being. Broader concerns about production problems have not been assuaged based on systematic studies and evidence. It is this wise that this study was initiated. The objective is to assess the economic viability of government-funded small-scale broiler projects in the KwaZulu-Natal Province of South Africa and determine the implications for poverty reduction and food security. Data were collected from the government-funded small-scale broiler producers that are residing in Northern KwaZulu-Natal districts uThungulu, Zululand and uMkhanyakude. A total of 75 small-scale broiler projects 25 broiler projects in each district were selected by probability sampling procedure for the interviews. Questionnaires that combined both close-ended and open-ended questions were used to collect primary data, which include production and marketing, as well as the factors that influence the profitability of the small-scale broiler projects. After collection, data were captured and encoded on spreadsheets in Microsoft Excel and exported to Statistical Package for the Social Science (SPSS) software version 26 and STATA for analyses. Descriptive statistics applied include frequencies and means. In addition, a gross margin (GM) and gross profit margin (GPM) analysis were employed to assess the profitability of government-funded small-scale broiler projects. Both profitability and gross margin analyses were used as proxies for farmers’ motivation and incentives to participate in broiler production. Further analyses were conducted to determine the model that best explains the underlying relationships. Initially, the Multiple Linear Regression Model was applied to determine the factors influencing the profitability of government-funded small-scale broiler projects. The indication was that while positive profits were revealed, the system seemed to fall short of its potential. In light of that, it was decided to fit another model to estimate the technical efficiency of the system and gain an understanding of the causes of any inefficiency that might exist in the production system. In that regard, the one-step Stochastic Frontier Model was employed to show that the technical efficiency of broiler production systems in the project area was positively and significantly influenced by flock size, the quantity of feeds and labour costs, while medication played no role possibly because of weak extension coverage. An inefficiency model fitted as part of the one-step model suggested that age, gender and educational level were significant influencers of technical inefficiency, with the possibility that the older the farmers, the more technically inefficient the system possibly because of the strenuousness of commercial poultry production. In addition, it was found that the more educated the farmer, the less inefficient the farm, which conversely means that the system becomes more efficient as the farmer receives more education. The negative coefficient of the gender variable also implies that for farms managed by female farmers, the system was less inefficient, which is more technically efficient, and this can be explained by women’s propensity to be more gentle, caring and sensitive in managing the chickens than their male counterparts. Heteroskedasticity tests and corrections were conducted in the one-step estimation technique to show that variations in the inefficiency term (μ) and the stochastic error term were explained by age and educational level for the most part. Clearly, improvements in the broiler industry in KwaZulu-Natal will depend to a large extent on the knowledge and experience of the farmers and substantial enlargement of the flock size of adequately fed birds. Attention to these elements is expected to have important practical implications for sustainable broiler poultry development and food security in the project area, as well as locations possessing identical features and characteristics. , Thesis (MSci) -- Faculty of Science and Agriculture, 2023

- Description: Generally, rural areas continue to experience high poverty levels and low incomes, which seem to be occasioned by high unemployment rates, limited educational attainments, and devastating floods and droughts. This situation is further exacerbated by increase in crime rates, making livelihoods even more difficult. To mitigate such adverse situations, rural households employ diverse strategies, including maintaining community gardens, one-home-one-garden schemes, as well as livestock and poultry production. The most prevalent livelihood strategy in South Africa or KwaZulu-Natal is broiler production, since it needs less space and a short production cycle compared to other livestock or crop enterprises. At the same time, income is generated over a short period. Besides, the government of KwaZulu Natal has actively intervened in the sector as part of its broader poverty reduction strategy and farmer support programmes. In KwaZulu-Natal Province, the provincial government has been supporting broiler producers for many years. While substantial research work has been done in the province on livelihood strategies, including livestock production on a province-wide basis, there is no information about how successful the broiler production funded by the government has being.

- Description: Sustainability has been the focal point of sustainable tourism development in South Africa for a number of years. The ability of attractions to depict the culture of an area and provide visitors with locally produced goods that remain economically viable for vendors, remains crucial for tourism development. Hence, farmers’ markets have recently been identified as potential visitor attractions that can provide sustainable development for communities. However, farmers’ markets and their clientele who attend have not received the necessary scholarly attention particularly within the Western Cape region of South Africa. To further understand what role farmers markets can play in the tourism economy; this study sought to examine the perceptions of visitors at the Outeniqua Farmers’ Market in George. The research objectives were: • To determine the demographic profile of visitors to the Outeniqua Farmers’ Market. • To ascertain the preferences of visitors with regard to the type of products offered at the Outeniqua Farmers’ Market. • To determine whether the Outeniqua Farmers’ Market serves as an attraction to visitors. • To analyse which factors motivate visitors to attend the Outeniqua Farmers’ Market. • To examine the visitors understanding of the impact of COVID-19 pandemic on the Outeniqua Farmers’ Market. To accomplish the objectives of this study, previous research undertaken was consulted in order to better understand how farmers’ markets were performing around the world. In addition, to what methodological approaches would be most appropriate to utilise for such a study. The literature consulted revealed disparate differences in perceptions between farmers’ market visitors in Northern as opposed to Southern hemisphere countries. The effects of COVID 19 and the influence of visitor perceptions on travel behaviour were expounded on. Also, previous research revealed that a quantitative survey would be useful for the study as respondents would be accessible at the farmers’ market to solicit information since it was a confined area. v The findings revealed that visitors were mostly locals to the area, comprising primarily white middle-aged females who often attend with family groups. Furthermore, visitors thoroughly enjoyed the overall experience the market presented. It is further complemented by the availability of ready-to-eat foods as well as the provision of social interactions within a secure environment, while scrutinising the environmental friendliness and uniqueness of the products. , Thesis (MA) -- Faculty of Business and Economic Science, 2023
