- Description: In this study, we discussed a mathematical model that incorporates important interactions between normal cells, tumor cells, immune cells, and estrogen. The mathematical model was revised to include two control measures; namely surgery and hormone therapy to minimize the number of tumor cells. The model was mathematically analyzed with the premise that the two control measures are positive constants. Locally and globally analyses were performed using a variety of analytical methods to investigate the stability of the breast cancer model. Furthermore, an optimal control problem was formulated and used to determine the best strategy for reducing the number of tumor cells by incorporating hormone therapy and surgery, based on the well-known Pontryagin’s Maximum Principle. The numerical results indicates combining both optimal control measures (surgery and hormone therapy) simultaneously is more efficacious than using single control measure separately in decreasing the number of tumor cells. , Thesis (MSc) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2023

- Description: This study focuses on the parental influence on next-generation family members in South African Black-owned family businesses. In both developed and developing countries, the majority of businesses are family-owned and contribute significantly to their country's economic growth. To be sustainable, family businesses should anticipate, recognise and understand the impact parents have on their next-generation family members’ intentions to join the family business. Controlling a family business with the intent to transfer it to the next family generation is often seen as the defining characteristic of family businesses. Transferring the control of a family business to the next generation presents a critical managerial challenge. It has been noted that parents are the most important influence in a child’s life and could therefore have the greatest influence on their career choice. This study discusses parents' impact on their next-generation family members’ career choices in the context of career choice theories: Holland’s theory of vocational personalities in the work environment, Super’s developmental self-concept theory, and social cognitive career theory. Moreover, the important influence that parents have on their children and the impact of the parent is elaborated on; the characteristics of the parent's job, self-efficacy, outcome expectations, parent's relationship, parental expectations, parent's style, and cultural influence are discussed. In addition, career choice theories in the South African context are also briefly discussed. The lack of desire of next-generation family members to join the family business endangers its long-term sustainability. Although numerous factors influence a person's career choice, including the decision to join their family business, parents are by far the most influential. Therefore, the primary objective of this study was to identify the influence parents have on a next-generation family member’s intention to join the family business. A structured questionnaire was distributed to South African respondents with parents who own a family business. Respondents were identified by means of judgemental sampling. A total of 317 usable questionnaires were subjected to statistical analysis. The validity of the scales measuring the dependent and independent variables was assessed using factor analysis, and the scales’ reliability was confirmed by calculating Cronbach’s alpha coefficients. Both descriptive and inferential statistics were calculated. The family businesses iv associated with the respondents were mostly first-generation owned. The majority of respondents were Xhosa and Zulu speakers and represented family businesses that employed more than five employees. The next-generation family members who participated in this study were predominantly males under the age of 25 years, and most had no post-matric qualification. Multiple regression analysis was used to assess the hypothesised relationships. The results indicate that four parental influences (parental style, culture, self-efficacy and parental identification) significantly influence a next-generation family member’s intention to join the family business. It is important for parents to understand which factors influence their children's decision to join the family business, as this allows the parents to manage these factors best. , Thesis (Ma) -- Faculty of Faculty of Business and Economic Sciences, 2023

- Description: The high rates of unemployment and poverty in South Africa are significant barriers to economic advancement in the country. According to Statistics South Africa (2022), the country’s unemployment rate is 34.5 percent, while it has been reported that the proportion of the population living in poverty was 55.5 percent in 2020. Social entrepreneurship has been recognised as a means of tackling these socioeconomic challenges, by providing innovative social solutions. However, the lack of a universal definition for social entrepreneurship has caused misperceptions regarding its potential for job creation, poverty alleviation and economic development. In order to understand the relationship between social entrepreneurship and job creation, this study focused on existent perceptions of social entrepreneurship as pertaining to job creation in South Africa; the study used the Buffalo City Metropolitan Municipality as a case study. An in-depth literature review was conducted on the relevant literature related to the concept of social entrepreneurship, and its role in job creation. This study employed a qualitative research approach, in this respect, it relied on inductive reasoning. The research design followed the hermeneutic phenomenological method, for which non-probability purposive sampling was used in order to select participants. The study sample comprised of twelve social entrepreneurs registered on the Buffalo City Metropolitan Municipality's Local Economic Development database for social entrepreneurs. For the purpose of data collection, the study employed semi-structured interviews which relied on open-ended questions; in this regard, the study achieved a 100 percent response rate. The primary research findings indicated that the youth of the Buffalo City Metropolitan Municipality participate in, and promote, social entrepreneurship as a solution to the metropole’s high youth unemployment rate. The results of the study support current government policy by encouraging the implementation of local government policy initiatives that support social entrepreneurship, which could eventually result in the creation of jobs, and a decline in the country's unemployment rate. In addition, the study identified the need for government support, specifically in terms of the provision of funding and resources as a perceived government function; this would assist in the creation of social entrepreneurshipbased jobs. The study contributes to the existent body of work on the phenomenon of social entrepreneurship, and to further understanding the role this phenomenon plays in job creation in South Africa. Local government should acknowledge and support social entrepreneurship through the improvement of its current systems and the reallocation of government resources, so as to encourage openness and participation, in order to foster an environment that is vi favorable to social innovation. Furthermore, by capitalizing on the commercial aspects of social enterprises, and abandoning reliance on traditional Local Economic Development policies, local government can develop policy frameworks that promote socio-economic development in the Buffalo City Metropolitan Municipality , Thesis (MA) -- Faculty of business and economic sciences, 2023

- Description: Mental illness has become a global concern, with consequences that may result in a mental health pandemic. Studies conducted on mental illness suggest that religious and cultural beliefs not only affect the expression of mental illness, but also the diagnosis and treatment of mental conditions. South Africa is a country imbued with cultural and religious diversity, which creates different groupings of people, holding diverse beliefs regarding mental illness. In many contexts, supernatural beliefs, traditional healing and indigenous medicines and treatments are considered in the treatment of the symptoms associated with mental illnesses, especially on contexts where there is a reliance on religio-cultural beliefs. Even though there has been a significant increase in the contribution to research focusing on mental health in diverse contexts, much of this research has focused on subjective experiences. Little to no information is available on population-based studies in South Africa regarding mental illness in diverse contexts, thus limiting the generalisation of findings related to cultural and religious influences on mental illness. This dearth of information further limits the development of psychological interventions. The study aimed to explore how mental illness is perceived by the participants and thereafter explored the influence of culture and religion in coping with mental illness by the residents of the Eastern Cape. The study was quantitative in nature and adopted an exploratory-descriptive design. The researcher made use of a questionnaire as a research tool and QuestionPro was utilized as a platform. A convenience sampling technique was utilised. In ensuring rigour of the study, the researcher ensured maximal validity (accurate representation of the data) and reliability (ability to repeat the research procedure). Ethical principles have been adhered to as per the principles on the Belmont Report, to ensure safety of the participants and this includes anonymity, confidentiality and the right to withdraw from participation in the study. Data has been analysed using descriptive and inferential statistics. A sample size of 101 participants from the general population of residents of the Eastern Cape completed the online survey. The results of the study revealed that the residents of the Eastern Cape have substantial knowledge pertaining the cause of mental illness and indicated both positive and negative attitudes towards the mentally ill and possess coping strategies to deal with a mental illness. In addition, the results show that there is a relation between religion/culture and coping with a mental illness by the participants of the study. The findings of this study emphasize the necessity of public education efforts that understand and respect people's cultural diversity, as well as teamwork among traditional and medical professionals. Future studies should focus on the use of discourse analysis to better investigate indigenous groups' conceptions of mental illness and their views about its aetiology and treatment. , Thesis (MA) -- Faculty of Health Sciences, School of Behavioural Science, 2023

- Description: Personal Branding is deemed as an unavoidable aspect of entrepreneurship and social acceptance. Individuals should establish, develop, maintain and take advantage of a Personal Brand. The benefits of a Personal Brand should be embraced and used to market themselves and highlight their uniqueness. The aim is to investigate the relationship between Professional Life, Social Media Presence, Values, Competencies, Communication as the independent variables and Personal Branding as the dependent variable. It was concluded that there are important factors that positively influence Interpersonal Personal Brand as well as Intellectual Personal Brand, which are the two components that make up Personal Brand. There is limited research on the factors that influence Personal Branding in South Africa. Through literature review, factors were identified and used to form a conceptual model. This model was tested to measure their relationship with Personal Branding. An online questionnaire was distributed to MBA students, family and friends who made up the study’s respondents. The results obtained after conducting correlation and ChiSquare tests were used to determine the relationship between the identified factors with Personal Branding. This study explores how individuals can use Personal Branding as a marketing tool. These individuals include those who want to create or further expand their current Personal Brand and use it as a marketing tool. This treatise explored the factors needed to be considered for Personal Branding a marketing tool for individuals. Personal Branding can be used at the beginning of a career, during a transition of a career or even when wanting to explore a new career. Personal Brand was initially considered the only factor. However, this study concludes that Personal Branding is made of up of two components: Interpersonal Personal Branding as well as Intellectual Personal Branding. The findings concluded that independent factors, Professional Life, Values, Competencies and Communication all have a positive significant influence on Personal Branding as a whole, as well as the components it is made up of, Interpersonal Personal Branding and Intellectual Personal Branding. The independent factor Social Media Presence positively influences Interpersonal Personal Branding only. v This study makes theoretical contributions by broadening the definition of Personal Branding. The study defines the research methodologies for Personal Branding which could be used for future studies. The Associative Network Theory in relevance to Personal Branding is explored. The practical contribution of this research includes a hypothesised model which was tested. This study should be repeated to include a bigger sample size that is more equally distributed within South Africa. Additionally, for future studies, it would be recommended to incorporate the development of Personal Branding as an independent factor to measure its effect on Personal Branding. Another recommendation for further research is to conduct research on policies, which can be put forward to assist with the managing of Personal Branding for entrepreneurs. , Thesis (MSc) -- Faculty of Business and Economic Sciences, 2023

- Description: This study endeavoured to investigate the perspectives of principals and practitioners working in selected early childhood development (ECD) centres in the Buffalo Municipal District in the Eastern Cape, on the use of play-based techniques in educational and pedagogical practices of 3 to 4 years age group. Although most practitioners are aware of the significance of play-based learning, many report experiencing challenges when attempting to incorporate play-based strategies into their teaching of, and lessons aimed at, young children ages 3 to 4 years. For the purpose of ECD, it is recommended that the teaching of, and learning by, young children take the form of play (NCF, DBE, 2015). In this particular research undertaking, a qualitative design approach was adopted. A descriptive case study approach with semi-structured interviews as the key method of data generation was used to study play-based approaches between practitioners and children ages birth to four years at three ECD centres located within the Buffalo City Municipality District. Face-to-face interviews were conducted with the three principals of the ECD centres and six practitioners, during the data-collection phase. Recording of the interviews was done then they were transcribed and thematic coding employed before the data were analysed for themes. The study participants’ responses revealed that the insufficient professional training of practitioners, on play-based approaches, presented a challenge. Play as a way of teaching and developing young children is further hampered by a variety of issues such as poor infrastructure, unqualified practitioners, funding of the ECD centres and lack of relevant resources prevalent in the ECD sector. As the findings indicate, government intervention will facilitate the training of practitioners for in-depth knowledge and understanding of play methodology in ECD, while the sector will benefit from additional funding and infrastructure provision as this has impact on indoor and outdoor play-based activities, as well as the appointment of qualified human resources instead of job seekers. , Thesis (MEd) -- Faculty of Education, 2023

- Description: The South African public sector has become known for poor service delivery due to a number of factors; these factors include a lack of innovation, or inadequate innovation, which could be as a result of the compliance requirements of various laws and regulations. As a result, the public sector must find ways to innovate within its operating context, even as efforts are being made to reform its structure and manner of operation. This research followed a case study approach, focussed on a provincial government department in the Western Cape province of South Africa, in order to investigate the role of leader-initiated innovation triggers in motivating employees to innovate. The premise was that staff would be motivated to innovate if public sector top leadership demonstrate that it is possible to do so within the current operational framework; this would, potentially, lead to the successful establishment of an innovation culture within the organisation. The methodology employed in this empirical study was exploratory sequential mixed methods research. Senior management from the case subject organisation were interviewed in order to obtain their views on pertinent issues relating to the research topic. Themes that emerged from the interviews were combined with key elements from the literature review in order to formulate a model of how leader-initiated innovation triggers can potentially motivate employees to innovate. The model was subsequently tested, quantitatively, using a questionnaire survey. The study responded to the primary research objective by establishing the existence of moderately positive relationships between leader-initiated innovation triggers and employee motivation to innovate; this confirmed that leaders' display of certain practices, actions and behaviours can motivate employees to innovate and, subsequently, help build an innovation culture within a bureaucratic public sector environment. , Thesis (MA) -- Faculty of Faculty of Business and Economic Sciences, 2023

- Description: Forest nurseries are exposed to many challenges during the production of plant material, with pests and pathogens two of the most important. Management of pests and diseases require the use of multiple methods, including cultural, biological, and chemical control strategies in an integrated nursery pest management plan (IPM). In most nurseries, where hygiene practices and biological controls do not prevent the presence of pests and pathogens, they are managed through the use of pesticides. Forestry companies are regulated by both Government and Forestry Certification bodies. These include South African legislation pertaining to pesticides regulated by the Registrar Act 36 of 1947, the Forest Stewardship Council (FSC) and the Programme for the Endorsement of Forest Certification (PEFC). A limited number of pesticides, with an even more limited range of active ingredients, and not targeting all known plantation forestry pests/pathogens, are currently registered for use against pests and pathogens in plantation forestry in South Africa. Many of these have been in use for more than a decade, posing a serious risk in terms of resistance build-up. There is a major need for the identification and testing of additional/alternative products (biological natural or synthetic) for use against the range of pests and pathogens that occur on the various plantation tree species and hybrid combinations that are raised in nurseries. , Thesis (MSc) -- Faculty of Science, School of Natural Resource Science & Management, 2023

- Description: The South African education system is severely faced with high dropout challenges. In recent years, the Department of Basic Education witnessed a significant improvement in learners' dropout rates. To address the high rates of learners dropping out of school, the government introduced the Policy on Progression (2013). This study aimed to explore teachers’ perceptions of the Policy on Progression. The qualitative research approach guided this study. A phenomenology was employed in this study. Purposive sampling was chosen to select the participants of this study. Teachers teaching in the FET Phase in New Brighton high schools participated in the study. The participants consisted of ten (10) teachers, two (2) Post Level 1, and three (3) School Management Team (SMT) members from each school. Semi-structured interviews were used to collect data for this study. The research procedure involved interviewing teacher participants about their lived experiences within the context of their teaching environments. Raw data were transcribed, analysed using thematic analysis, and reduced into smaller units to understand them. The raw data were categorised into units of meaning for analysis and the identification of themes. A policy can negatively impact teaching, learning, and assessment if not interpreted correctly and implemented appropriately. This impact of interpretation and implementation of this policy has behavioural implications that affect the well-being of learners and teachers. In this study, the researcher sought to understand whether teachers and the school management teams believe that the Policy on Progression has yielded the intended results by exploring teacher perceptions dealing with high school progression. Thus, new understandings of the policy would emerge, and the participants would advise the stakeholders about the policy from an informed position. The findings of this study reveal the fair part of the Policy on Progression on learners, as it allows continuity. The findings further reveal that the Policy on Promotion has yielded the intended results. However, the findings of this study revealed a partial relationship that exists between the parents of the progressed learner. Furthermore, the findings indicate challenges in the Policy on Progression such as favouritism, inconsistency, lack of monitoring from the Department of Basic Education, and inferences with the progression process. , Thesis (MEd) -- Faculty of Education, 2022023

- Description: Throughout the recent history of South Africa, the increasing requirements from state and private sector healthcare institutions have relied heavily upon medical imaging technologies for the purposes of improved patient healthcare and service quality standards. Developments in this field of healthcare have seen many interesting and challenging operational changes: from the first implementation and use of X-ray equipment demonstrated in Krugersdorp in 1899; to the current advanced digital systems found in the medical imaging services sector of healthcare. This research study measured the medical imaging operational staff perceptions about new advanced medical imaging equipment and technologies. The theory crossed the academic disciplines through a quantitative survey about technology, operations management and healthcare. Together with staff perceptions about future medical imaging technologies’ usefulness and ease of use, the findings may impact their daily operations within a conducive technology acceptance management paradigm. , Thesis (MA) -- Faculty of Faculty of Business and Economic Sciences, 2023

- Description: The notion of public participation in decision-making processes is one of the mechanisms that seek to entrench equality and transform social coherence between government and citizens. This view relates to the provision of quality and sustainability of goods and services. The individuals, both in their capacity as citizens and consumers of public goods and services should be allowed to participate in the development that affect in terms of the regulatory frameworks. They should be permitted and encouraged to express their views on governance and development matters pertaining to them. Nevertheless, there are number of factors that impede the participation of the local communities in development planning processes, such as a communication gap between government officials and communities, socio-economic inequalities, poor service delivery, unemployment, a lack of capacity building and transparency to mention a few. The planning and implementation of municipal projects should be accepted only after considerable discussion and consultation with communities. This process is seen as allowing deprived groups and individuals to have voices in future development initiatives. As such, public participation enables for full involvement of ordinary members of the community in decision making, planning, designing, organising and executing development initiatives that affect them. The Researcher decided to embark on a study entitled: The assessment of public participation as a model to enhance development in local government. The case of Raymond Mhlaba Local Municipality in the Eastern Cape. Adopting the quantitative research design, data was collected through questionnaires for the key informants consisting of 3 participants, 3 officials from Raymond Mhlaba Municipality. Data was also collected through in-depth semi-structured interviews with members of the communities from Kataga in Adelaide, Gaga Village in Alice and Magaleni location in Fort Beaufort. Eighteen (18) community members were selected to participate in the study from both communities inclusive of ward councillors. Community members were organised into 1 focus group participants in each location (comprising of 6 people per group).To support the data obtained from focus group 3 key informants from Raymond Mhlaba Municipality participated in the investigation. A heterogeneous population of 21 respondents participated in this study. The thematic analysis was vii used to analyse data. The findings consistently show that the ability of a local government to work effectively dependent on inclusive planning, implementation and decision making processes. This means that local government development is also required for the impartial and efficient operation of public institutions. Public confidence in local municipalities is expressed as one of the main factors that determine the government‘s competitiveness. , Thesis (MA) -- Faculty of Faculty of Business and Economic Sciences, 2023

- Description: The rise of humankind has caused pollution, increasing damage to the environment. The actions of humans over hundreds of years have led to an increase in the release of heavy metal cations in concentrations that are toxic to plants, animals and humans. These toxic metals can find their way into humans’ diets through water sources or bioaccumulation in plants and animals such as fish. Heavy metals such as lead and mercury are known to cause serious health issues when consumed, affecting the functioning of the circulatory and nervous systems and causing developmental disorders. Other metal cations, such as iron and copper, can be found in the human body. However, detrimental health issues can occur when normal concentrations are disturbed (either too high or too low). Iron, for example, can be toxic if in excess in the human body, causing damage to the liver and heart and can cause neuroinflammation and Alzheimer’s disease. Many methods have been employed to detect and measure the concentrations of toxic metal cations. However, these methods are performed in a laboratory and need skilled operators using expensive equipment. This results in long and tedious sample collection, long feedback time and costly analysis. Chemosensors have been researched and proposed as a cost-effective, on-site, real-time alternative for use as metal detectors. Chemosensory can selectively detect specific metal cations and can be sensitive up to the nanomolar range. Various chemosensors have been synthesised and screened for their colourimetric and fluorometric abilities. Colourimetric chemosensors can be used to visually detect cationic and anionic analytes, whereas fluorometric chemosensors are used to detect anions using their emission properties which handheld devices can measure. , Thesis (PhD) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2023

- Description: The global livestock production systems are changing due to a variety of factors, which have an impact on the price of red meat. The supply of weaners (cattle) is affected by a number of factors including the type of production system, feed costs, diseases and weather conditions. The demand for weaners (cattle) is affected by factors including, amongst various others, consumers’ perception of quality, value for money, health benefits, economic profile, expandable income, urbanisation and socio-economic factors. These factors are complex and interrelated in terms of their potential impact on weaner prices and have a significant influence on production and investment decisions in the industry. This study used quantitative research to investigate the relationship between the factors influencing the price of weaners (cattle). For the purpose of data collection, a closed ended questionnaire was distributed to the respondents. This study was done using non-probability sampling. The sampling method used in this study is referred to as snowball sampling, which is a process using networks. The data was analysed to conclude which factors are impacting the price of weaners (cattle) the most. The results show that the supply factors of weaners are experiencing increasing pressure with changing weather conditions, input costs and animal diseases. The demand factors such as quality, currency and population are increasing the complexity, which implies the market is changing from a producer orientated market to a consumer orientated market. The study provides a framework to predict future prices of weaners, which is expected to influence both production and investment decisions which contribute toward the sustainability of the industry. The study recommends that the South African weaner (cattle) industry has experienced a significant increase in demand, both locally and globally. Meeting this growing demand has its own complexity that limits weaner farmers’ supply of weaners.

- Description: This study examines the effect of Illicit Financial Flows (IFFs) and capital flight on Zimbabwe’s economic growth and development. The study data covered the period 1980-2020 applying the Autoregressive Distributed Lag (ARDL) regression model to assess the relationship between IFFs and capital flight and Zimbabwe’s economic growth and development. Most empirical studies on developing countries show that in both the short and long run, IFFs and capital flight not only reduce the revenue base of the economy but its multiplier effects result in a negative significant relationship between economic growth and development. This supports the continued call for policymakers and government to develop effective policies and continue to have intergovernmental and bilateral engagements to share knowledge and information to deter and control these activities. Unless these activities are controlled, most developing countries will have revenue shortfalls that will have to be funded from Other Donor Assistance (ODA), AID and loans. The study used two ARDL models to assess the impact of GDP and Manufacturing output to assess the impact. GDP and Manufacturing output have been chosen as the proxies of economic growth. Data showed that capital flight had a positive coefficient relationship with GDP in the long run. It was statistically significant and capital flight also had a negative and insignificant effect on manufacturing output during the period 1980-2020. Thus, Zimbabwe should effectively engage in policies and measures that identify and deter IFFs and capital flight activities because the multiplier effects of the activities have a negative impact on economic growth and development. The continued depletion of state resources discredits the objectives of the government to achieve the 2030 Millennium Development Goals. Government expenditure in nonproductive sectors must be avoided, instead, priority must be given to sectors that attract investors and stimulate economic growth and development. , Thesis (MA) -- Faculty of business and economic sciences, 2023

- Description: As the researcher believes leaders and leadership to be products of both nature and nurture, this phenomenological study was focused on the use and effectiveness of action learning methodology to develop first-line leadership competence. This study aimed to understand the training and developmental experiences of first-line managers during a leadership development programme using an action learning approach. The main research question: “How effective is action learning in developing first-line leadership competence at BASF South Africa”, was supported by five secondary research questions focused on the KASH-in-Transit Leadership Programme and the extent that participants, mentors and departmental managers perceived that action learning developed the leadership competencies of participants, and specifically leadership competence aligned to the BASF Global Competency Model. It also focused on the factors, elements or conditions in the KASH-in-Transit Leadership Programme that were effective and/or ineffective in developing these leadership competencies. Using these research questions as a guide, the current study posed open-ended interview questions that explored participants’ experiences in developing competencies aligned to the BASF global competency framework. The theoretical framework for the study was guided by the constructs of adult learning, action learning and leadership development as well as the link between learning, action learning and leadership development. Data was collected from 15 participants (12 coater drivers, 2 mentors and 1 manager) through the use of observations, action learning sessions and semi-structured interviews, with the interviews transcribed and then analysed using Atlas.ti qualitative analysis software. The information collected and succeeding analysis may help the development of future leaders within BASF South Africa as well as help close the gap in the literature on action learning as a leadership development tool. Action learning as a modern-day approach is capable of developing leadership at multiple levels and contexts, building collaborative partnerships and networks that aid in organisational development. The research findings led to the development of five themes surrounding the phenomenon of action learning as a means to develop first-line leadership competence: (1) Learning transfer has internal and external levers, (2) viii 70 + 20 + 10 = leader and leadership competence, (3) Facilitator and Mentor are catalysts for action AND learning, (4) Leadership development is built with connections and stumbling blocks, and (5) Development is part of succession. Individuals were challenged through exposure to real-world practices while being supported by a facilitation and mentoring system that offered critical, constructive feedback. The objective was to create career experiences and establish environmental influences that will stimulate developmental growth while facilitating an individual’s ability to learn from experience. , Thesis (MA) -- Faculty of Faculty of Business and Economic Sciences, 2023

- 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
