- Description: The Labour Relations Act (LRA) recognises settlement agreements and arbitration awards as mechanisms by which the rights of parties in troubled employment relationships can be asserted. Commission for Conciliation Mediation and Arbitration (CCMA) is a statutory body empowered to make and pronounce on such rights through settlement agreements and arbitration awards. The CCMA caters for those earning within the stipulated ministerial threshold falling outside the existing bargaining forums. However, not much empirical evidence is available to indicate the challenges experienced by parties when attempting to enforce those CCMA rulings to get defaulters to comply. South African law accepts settlement agreements as part of dispute resolution mechanism, but the experience of some who hold settlement agreements is such that they are exposed to prejudice when they are required to have the settlement agreement converted to arbitration awards which essentially requires alteration of the very settlement agreed upon. The broad objective of taking matters to the CCMA for resolution with the possibility of having them resolved at conciliation phase cannot be achieved if a settlement agreement is not worth the paper written on and must be made an arbitration award for enforceability. The two are not the same, nor should they be made to be and trying to give them a similar status for enforceability purposes brings about a myriad of unintended challenges. While it could be argued that there also exists section 158 (1) (c) of the LRA if the requirements of section 142A are challenging, it could also be said that such a provision is inaccessible to indigent individuals who may only be able to invoke that provision at the mercy of legal practitioners willing to take cases pro bono for those parties to even stand a chance at enforcing compliance with a settlement agreement that was entered into voluntarily. Such a system allows for employers to bail out on settlement agreements without consequence make a mockery of the CCMA. To a serious degree, this suggest lack of certainty on the part of CCMA and its ability to bring matters to finality which is an important element to realisation of justice. This study sought to examine the way settlement agreements and arbitration awards are enforced, with dedicated focus on the requirement that must be satisfied in order to have force and effect. With the above in mind, chapter one dealt with how settlement agreements and arbitration awards are given force and effect through the LRA as envisaged in section 142A. The chapter explored challenges brought by the enforcement process and what that may mean to the objectives intended by the legislation. Chapter two encapsulates the framework under which the CCMA operates and enforces its decisions, a framework envisaged to be less formal and non-legalistic for the expedient resolution of labour disputes. Chapter three touches on the challenges met with section 143 implementation and highlights some case law prior and after the LRA amendments. Lastly chapter four looked into the enforcement of international or foreign arbitration awards within the South African context given the affiliation with international organisations such as International Labour Organisation (ILO). While it may be good for South Africa to align herself with international practices, it is worth noting that South Africa is still developing in international arbitration as a mode of alternative dispute resolution, but its prevalence as a preferred dispute resolution mechanism is without a doubt increasing. , Thesis (LLM) -- Faculty of Law, School of Mercantile Law, 2023

- 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 Criminal Law (Sexual Offences and Related Matters) Amendment Act 32 of 2007 (“SORMA”), was promulgated to consolidate the laws relating to sexual offences in South Africa. One of the most important aspects of SORMA was that it made provision for the prosecution of those who engaged in sexual acts with minor children. However, SORMA had a major drawback in that it not only criminalised consensual sexual acts with children by adults, but also criminalised consensual sexual acts between children themselves. Thus, children could be prosecuted for engaging in consensual sexual conduct with each other. Stemming from this peculiar position, the provisions of section 15 (statutory rape) and section 16 (statutory sexual assault), insofar as they related to the prosecution of adolescents for engaging in consensual sexual acts with each other, was constitutionally challenged by various human rights organisations. The Constitutional Court in Teddy Bear Clinic v Minister of Justice and Constitutional Development 2014 (2) SA (CC) found that the provisions of section 15 and 16 of SORMA were unconstitutional insofar as they criminalised consensual sexual acts between adolescents older than 12 but younger than 16. The original version of SORMA, for purposes of sections 15 and 16, defined a child as a person under the age of 16 years. Only children younger than 16 years received protection under SORMA. The provisions of sections 15 and 16 of SORMA were the subject of a constitutional challenge in Teddy Bear Clinic. However, the position of 16 and 17 year old children was not dealt with, as it did not form part of the issues that had to be decided by the court. Subsequent to the Teddy Bear Clinic judgment, SORMA was amended, and the amended version defined a child as a person younger than 18 years. Despite this, 16 and 17 year old children did not fall within the ambit of protection provided by SORMA. They were still exposed to prosecution for consensual sexual acts with their adolescent counterparts. Moreover, they were not protected against adult sexual predators who prey on young children. Effectively, SORMA provided some degree of protection, but such protection is not sufficient, and it is contrary to the best interests of the child principle. vi Thus, this research project seeks to highlight, assess and criticise the failure of SORMA to provide adequate legislative protection to 16 and 17 year old children. They still face the possibility of prosecution for consensual sexual acts with other adolescent children, and, they are not offered any protection from adult sexual predators. This position is unacceptable as it is contrary to the spirit and purport of the Constitution, specifically the best interests of the child principle, an important international law principle. Article 3 (1) of the Convention on the Rights of the Child provides that in all matters concerning children, the best interests of the child shall be a primary consideration. The African Charter on the Rights and Welfare of the Child provides that in all actions concerning the child, the best interests of the child shall be the primary consideration. Thus, the lack of protection of 16 and 17 year old children under SORMA is not only contrary to the Constitution, but also to a fundamental international law principle. , Thesis (LLM) -- Faculty of Law, School of Criminal & Procedural Law, 2023

- Description: The Criminal Law (Sexual Offences and Related Matters) Amendment Act 32 of 2007 (“SORMA”), was promulgated to consolidate the laws relating to sexual offences in South Africa. One of the most important aspects of SORMA was that it made provision for the prosecution of those who engaged in sexual acts with minor children. However, SORMA had a major drawback in that it not only criminalised consensual sexual acts with children by adults, but also criminalised consensual sexual acts between children themselves. Thus, children could be prosecuted for engaging in consensual sexual conduct with each other. Stemming from this peculiar position, the provisions of section 15 (statutory rape) and section 16 (statutory sexual assault), insofar as they related to the prosecution of adolescents for engaging in consensual sexual acts with each other, was constitutionally challenged by various human rights organisations. The Constitutional Court in Teddy Bear Clinic v Minister of Justice and Constitutional Development 2014 (2) SA (CC) found that the provisions of section 15 and 16 of SORMA were unconstitutional insofar as they criminalised consensual sexual acts between adolescents older than 12 but younger than 16. The original version of SORMA, for purposes of sections 15 and 16, defined a child as a person under the age of 16 years. Only children younger than 16 years received protection under SORMA. The provisions of sections 15 and 16 of SORMA were the subject of a constitutional challenge in Teddy Bear Clinic. However, the position of 16 and 17 year old children was not dealt with, as it did not form part of the issues that had to be decided by the court. Subsequent to the Teddy Bear Clinic judgment, SORMA was amended, and the amended version defined a child as a person younger than 18 years. Despite this, 16 and 17 year old children did not fall within the ambit of protection provided by SORMA. They were still exposed to prosecution for consensual sexual acts with their adolescent counterparts. Moreover, they were not protected against adult sexual predators who prey on young children. Effectively, SORMA provided some degree of protection, but such protection is not sufficient, and it is contrary to the best interests of the child principle. vi Thus, this research project seeks to highlight, assess and criticise the failure of SORMA to provide adequate legislative protection to 16 and 17 year old children.

- Description: The Living Archive as Pedagogy emerges from Northern Uganda’s experience of war 1986- 2008, between the Lord’s Resistance Army and the Uganda People’s Defense Force previously named the National Resistance Army. This period of war and post-war has been a difficult experience where finding solutions and mechanisms for transition or justice remain complex, restricted, delayed and consequently concealing the reality of lived marginalization from below. The Acholi of Northern Uganda went through predatory atrocities, painful humiliation and unwilled cohabitations with their oppressors during war and post-war. The study explores how the interlinking of archives and pedagogy as independent disciplines can extend possibilities for more transformative education horizons in bottom-up, post-conflict expressions. The study is immersed through a conceptual and theoretical framing in the boundaries of archiving and pedagogy, to understand how the war constructs Acholi’s lived experience in multiple complex ways. While the Acholi re-orient their lives post- war, we recognize their attention in affirming their human agency, ordering of new and different meanings, desiring a different liberation in post-conflict where responsibility in contexts of “up againstness” validates their dwelling and being in spaces that exclude them. The research acknowledges that pedagogy and archiving studies in post-conflict, needs restructuring to challenge the preserving of external and dominant epistemological purviews that order post-conflict reconstruction life. These traditions exclude the experiences of survivor-victims, are tone deaf to community-based groups articulations of post-conflict repair, and neither does lived experiences of the everyday gets organized as an outcome for knowledge. This is discussed at length, as the research responds to its central question of how living archive as pedagogy can offer a transformative education discourse. The conclusion of the study emphasizes self-representation through transformative knowledge positions of I am whom I am, Where I am, Where I Speak, and Where I think. These positions articulate a self-understanding that supports rehistrocizing of post-conflict society as a body resisting exclusion in dominant knowledge formation and institutional omissions. There is evidence of the research foregrounding the formation of person-hood from experiences of ‘up againstness” and knowledge/under-stand[ing] from below. The research facilitates a hermeneutical encounter with specific inscribed bodies of post-conflict experience, the Acholi and Wanjiku whose bodies archive a horizon of possibilities if a different and difficult reading vii of the world is done from locations of struggle to produce consciousness of re-becoming, or returning to the human. These pedagogical experience positions Acholi and Wanjiku as educators, and their lives a living archive. We the readers are invited to a learning process as willing ‘hearers’ of Acholi and Wanjiku testimony, to own responsibility as our practice to ensure they appear in the world to say their truth, as they defy conditions of their oppression. , Thesis (PhD) -- Faculty of Education, School of Education Research and Engagement, 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

- 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

This was done to determine the extent to which Natalie du Toit underwent developmental growth as a result of posttraumatic growth after recuperating from her trauma. Tedeschi and Calhoun’s Posttraumatic Growth Model was used to inform the research. This model was used to describe the life experiences and events that characterised the posttraumatic adjustment of Natalie du Toit and interpret these through Tedeschi and Calhoun’s Posttraumatic Growth Model. The findings revealed a significant extend the existence of all five variables of Tedeschi and Calhoun’s Posttraumatic Growth Model, in the life of Natalie du Toit. , Thesis (MA) -- Faculty of Business and Economic Sciences, 2023

- Description: Money laundering has become common in the world and the introduction of cryptocurrencies has created another avenue that makes it easier to move funds between jurisdictions without anyone knowing. A block chain technology is used to process peer-to-peer electronic payments utilising decentralised virtual currencies known as cryptocurrencies. Although they are not yet regulated, cryptocurrencies are prevalent in South Africa and pose a risk of being used for money laundering and other illicit activities. The regulation of cryptocurrencies in South Africa to prevent money laundering is what is being examined by this research project. The objectives were to understand the concept of money laundering, cryptocurrency and the inherent risks of cryptocurrency in money laundering. An analysis and examination of the difficult concept of cryptocurrency and the risks of money laundering was done. The study demonstrated that cryptocurrencies are decentralised convertible virtual currencies based on cryptographic algorithms. Cryptocurrencies are not monitored by a central body. The research reveals that the use of cryptocurrencies presents risks of money laundering and other illegal activities because of its decentralised, anonymous, peer-to-peer, and unregulated nature. The study focused on the prevention of money laundering using cryptocurrency. International regulatory frameworks of countries such as Canada, United States of America, European Union and Australia were discussed and compared to the South African regulatory developments. It was established that the legal frameworks developed by Canada, the United States of America, the European Union, and Australia aim to mitigate the risk of money laundering associated with the use of cryptocurrencies. Additionally, it was discovered that there is no legislative framework in South Africa to regulate cryptocurrencies, however SARB acknowledged that efforts are being made to develop one. ix It was determined that South Africa urgently needs regulatory interventions in the continued use of cryptocurrencies. The author presented recommendations based on this need, including incorporating cryptocurrencies into the current legal framework by designating them as financial products and adopting a proactive rather than a reactionary approach to the developments of cryptocurrencies. , Thesis (LLM) -- Faculty of Law, School of School of Criminal and Procedural Law, 2023

- Description: This study explores the mechanisms contained in the Employment Equity Act of 1998 (EEA) that are in place to ensure that all employers comply with the EEA. The research introduces the topic and the background of the EEA and further discusses its important provisions. The EEA is an Act which was adopted to enable section 9 and 23 (1) of the Constitution. It is there to ensure equality in the workplace. The purpose of the EEA is to eliminate unfair discrimination in the workplace and promote equity for designated groups. This research discusses the application of the EEA and its interpretation by our courts. It does this by discussing leading cases of the EEA and other relevant fields of the labour law. Amongst other discussions in the research is the case of South African Police Service v Solidarity obo Bernard. In this case, a white female employee referred a matter of unfair discrimination to the court for her non-appointment, even though she was the only one who qualified for the job. The employer had preferred a black female candidate for the position. The court held that the discrimination was fair and relied on the employers Employment Equity Plan to determine whether the discrimination was just and equitable in terms of section 36 of the Constitution. Thereafter, this research considers the role of different bodies or structures that are in place to ensure compliance and implementation of affirmative action policies as outlined in the EEA. At the centre of this research is the role played by the inspectorate, the Commission for Employment Equity, and the Director General of the Department of Employment and Labour. These are the structures of the Department of Employment and Labour that are charged with enforcement of the labour laws and policies. Each structure has its own legislative duties. For example, in terms of the EEA, the inspector must conduct inspections for the employer’s workplace, make recommendations for compliance where it is necessary, and issue fines as a final sanction for non-compliance. On the other hand, the Commission for Employment Equity (CEE) investigating compliance, issuing annual reports, doing compliance reviews, issuing certificates of compliance and non-compliance and awards etc. In addition, the research also explores the enforcement penalties imposed by the EEA. It also incorporates a comparative study between the penalties imposed by South Africa with that of Namibia and Canada. This study will show how Canada’s EEA and South Africa are lenient compared to the Namibian one. In Namibia, non-compliance is not only sanctioned with fines but with other harsh sanctions that have detrimental effects on non-complying employers. Finally, the research makes a summary and findings of the study. Thereafter, it discusses the failures and shortfalls of the EEA. These critiques are made in comparison with other EEA such as Namibia, and further the researcher offers her personal critiques and recommendations to the current system. It then concludes by summarising the findings of the final chapter , Thesis (LLM) -- Faculty of Law, School of of Labour Law, 2023

- Description: Many people, particularly in South Africa, turn to borrowing money to pay for their everyday expenses. It is also generally acknowledged that mortgage financing is crucial to our economy and that it should remain readily available to people with a variety of incomes. Banks, and other secured lenders need confirmations that their security is reasonably safe to ensure that this remains the case. A debtor with immovable property is preferred because should the debtor fail to comply with his contractual obligations and there is no movable property to attach, the creditor will proceed to attach the immovable property of that debtor. In South Africa the law relating to debt enforcement proceedings and the provisions of the Insolvent Act allow for the attachment of the primary residence of a debtor/insolvent. There is a judicial process that is followed for the attachment of the house through debt enforcement. During insolvency the debtor is divested of his property immediately after granting of the sequestration order. These proceedings go as far as stripping a poor person of even a RDP house that they obtained through the Housing Act, a programme designed to provide housing to the poor. This study examines the relationship between the right to access housing and the right to human dignity, considering South Africa's past, the idea of transformative constitutionalism, and the argument that the 1996 South African Constitution's transformative vision is one that is committed to addressing socio-economic inequality. The legal position in South Africa is compared to that of the United Kingdom and the recommendation made by the study is that a stay in proceedings during insolvency for a defined period before the home of the insolvent is sold in execution would help advance the goals of the government and protect rights of those people whose estates are declared insolvent. Further, a complete exclusion of RDP houses from debt enforcement proceeding and insolvency, is suggested. The rights to equality and the right to property are considered in favour of the creditor. All rights are considered against the limitation clause, and it is submitted that a stay in sale of the primary household for a specific period during insolvency proceedings and the complete exclusion of RDP homes from sales in execution and sales during sequestration would not amount to an unjustifiable limitation of the creditor’s rights. , Thesis (LLM) -- Faculty of Law, School of School of Private Law, 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: This study empirically investigates the nature of the relationship between savings and economic growth in SACU member countries, namely: South Africa, Botswana, Lesotho, Namibia, and Eswatini, using panel data for the period 1990-2021. A high savings rate is believed to be instrumental in stimulating economic growth, making it vital is for policy makers to understand the nature of the relationship existing between savings and economic growth in order to design and implement appropriate policies. To ensure robustness of the empirical results, this study applied different panel data estimation procedures. Using Pooled OLS, Random Effect, Fully Modified OLS, Dynamic OLS and Mean Group, Pool Mean Group and Dynamic Fixed Effect, the study discovered that gross domestic savings have a positive impact on economic growth among SACU member countries. Based on the results, gross domestic savings emerged with different coefficients indicating sensitivity to the estimation technique although statistically significant. Furthermore, the study dealt with the issue of linearity in the savings-growth nexus, by estimating the threshold level. Estimated results reveal evidence that gross domestic savings above 16 percent threshold have a negative effect on economic growth, while below the threshold, level savings impact economic growth positively. The study recommends, among other things, that policy makers design and implement policies that promote financial inclusion to mobilise domestic savings so as to increase economic growth. The major goal of economic policy should be to encourage households to save and ensure that domestic savings are invested in productive projects and sectors of the economy. , Thesis (PhD) -- Faculty of Faculty of Business and Economic 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

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: South Africa has a violent and oppressive past. They are various historical incidents1 of extreme cruelty perpetrated by the previous apartheid regime. Much of the modern South African democratic state was forged by protests. During the 1970s and 80s, the legislator by passing unjust laws was used to assist the government to maintain the oppression of the people of South Africa. From the Soweto uprising in the 1970s to the current service delivery protests of the 21st century, gatherings have always had the potential for deadly violence. The motivation for this research started with the emotions evoked by the iconic picture of the body of Hector Pietersen2 being carried after being shot by the police. Strikingly the images of the killing by the police of Andries Tatane conjured further questions concerning the use of deadly force within crowd management situations. The research undertook an analysis of the use of force by the police during crowd management situations. A brief analysis of South African law relating to the use of force by the police prior to 1996 is provided. There are legislative prescripts for the use of force during the maintenance of public order. It must be noted that the legislation falls short on providing clear, concise authority for the use of deadly force. Normally, the use of force by the police and civilians for the purpose of arrest is regulated by the Criminal Procedure Act3 , whereas the Regulation of Gatherings Act4 providing the authority for the use of force by the police in crowd management situations to preserve public order. At first glance, section 49 of the CPA seems to validate arguments that it violates some constitutionally protected rights, among which are the right to dignity, life, to freedom and security of the person, against cruel, inhuman or degrading treatment or punishment and to a fair trial, which includes the right to be presumed innocent. Section 49 however, withstood Constitutional muster as set out in Re: S v Walters & another. As the right to life is a non derogable right.5 The limitation of this right may lead to constitutional scrutiny. The emphasis will thus be on ensuring that the balance with regards to proportionality in the use of deadly force is maintained. During the research it became apparent that the police, especially during crowd management situations, served political interests.6 This had the unintended consequence that the laws were applied to suit the political narrative and not the rule of law. The use of force in the policing arena is controversial. It is very clear that any misuse of force in crowd management situations will evoke the historical wounds associated with apartheid. However, within crowd management, the use of force and the authority to use deadly force is absolutely necessary. The Marikana massacre was used to highlight the mistakes that police have made during inappropriate use of force and its catastrophic consequences.7 It was observed that the legislative framework concerning the use of force, whether under section 49 of the CPA or section 9 of the RGA, is incoherent and too complex. The research argues for simplicity and accuracy within policy and applicable legislative alignment. The linkages from the applicable legislation to the institutional policies should never be outdated or incorrectly formulated. The violent rhetoric from politicians such as ex-president Jacob Zuma, 8 Minister Fikile Mbalula 9 and Bheki Cele10 fuels the argument that the police are susceptible to misdirected notions and may cause the police act unlawfully. The Constitution requires the police to “enforce the law”11 and as such there is an obligation on the police to do this within the constitutional parameters. The correct use of deadly force will only be achieved if the SAPS adequately resource, train and regularly refresh their members regarding the use of force when policing protests. , Thesis (LLM -- Faculty of Law, School of Criminal and Procedural Law, 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). 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. These results influence how salt marshes are managed, and highlight how not recognising the importance of consumers, such as crabs, could misalign management objectives. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022
