- Description: In this portfolio I reflect on issues Covid-19 has brought to our communities and the possibilities of creating a brighter future. My music reflects the struggle that most people have faced in the last two years, the emotions and the conspiracies surrounding the experience, and the effect of solitude. In a time such as this it is almost inevitable that the music being composed is connected to the struggle in society at large. For ma composition is a journal of the heart. The pandemic has created a situation where most are out of touch with each other, have lost all previous routine and structure, where relationships are broken due to lack of personal contact, and almost everyone has unwillingly (or unwittingly) been thrust into self-reflection. Every day sees a new struggle to squeeze in all those pre-pandemic ideals so that some normalcy can be obtained, but this is not a time to be looking back. It’s a time to understand what we are going through, build new joy and excitement for this different life and learn to live the best we can with the opportunities we are given. There has not been a more important time to foster some form of connection with friends and family, and to be as strong and supportive as possible. The portfolio begins with a solo violin piece, Unwelcome Solitude, which exemplifies the loneliness and sadness during the various lockdowns over the last two years, with hints of the past and the difficulties in trying to resurrect pre-Covid-19 times. There are some unusual expressive markings to add to the descriptive effect within the piece. This is followed by The Pandemic, two serialism works: Panic and Pain scored for a string quartet. Both of these pieces apply a flexible use of serialism to emphasize out the emotional aspects of the music, and quite simply; the panic and the pain caused by Covid-19 and the country’s response to the pandemic as a whole. Finally there is a three movement chamber piece titled A Storm Series which quite literally represents the series of events that occur from the upcoming to the closure of a typical Highveld storm. Further than this, these pieces represent the series of events that occurred in South Africa from the first rumour of the Covid-19 virus starting to circle around the world, through the various lockdowns and progression of events in our country and abroad. The final movement of this series, Re-awakening, ends on a positive note representing the rainbow at the end of the storm, and the positive outlook for South Africa to keep persevering through the pandemic. , Thesis (MMus) -- Faculty of Humanities, Music and Musicology, 2022

- Description: This study explored how adult women who have experienced father 'absence' are represented in True Love magazine, a popular South African women's magazine targeting black women readers. The study examined nineteen articles published between 2016 and 2021 in True Love, featuring black women’s stories and clinical psychologists, which mentioned ‘absent’ fathers. Through the lenses of psychoanalytic, traditional African cultural, and feminist theoretical frameworks and their key concepts, the articles were examined in relation to how the effects on the adult women of complicated relationships with their fathers while they were growing up, were represented. The selected articles were analysed using Braun and Clarke's reflexive thematic analysis, and representational themes were identified guided by theoretical frameworks and familiarity with the scholarly literature on father ‘absence’ in South Africa. A wide range of childhood and young adult experiences of father-daughter relationships, and household circumstances, appeared alongside the strong maternal networks which supported these girls and women. Representations and themes of clinical psychologists involved Freudian psychoanalytic frameworks to describe the damaging psychological implications of ‘absent’ fathers, particularly affecting adult women’s capacities to form trusting intimate relationships with men. The adult women’s stories – largely successful businesswomen and/or celebrities in the arts, as represented by True Love feature writers and editors – presented themes of what the women had learnt from their mothers, and how they had overcome difficulties and obstacles. These themes included representations of resilience, and of being ‘survivors’, informed by empowerments from a feminist theoretical framework. These themes also represented the women as working psychotherapeutically to manage their past experiences and psychological distress, to transform their retriggering in adult heterosexual relationships, and to pursue healing and self-actualisation. These representations and themes are argued to have inspirational and motivating implications for girls and women in contemporary South Africa. They generate alternate stories about the longer-term effects and outcomes of father ‘absence’, rather than the prominent 'victim' stories in media and scholarly literature of young women doomed to suffer poor relationships and depression forever. , Thesis (MA) -- Faculty of Humanities, Psychology, 2022

- Description: The Covid-19 pandemic and the associated lockdown regulations suddenly elevated the importance of blended learning in South Africa and worldwide. This has prompted various international and national institutions into action, providing various support services to enhance fast digital adoption in higher education and facilitate out of classroom learning. In this regard, this paper views the pandemic as a necessary evil that can catalyse the adoption of digital learning, particularly, in rural-based universities of South Africa that have been lagging in the digital education front. The paper reviews recent literature and document opportunities that are emerging from the Covid-19 pandemic. These opportunities can assist rural-based universities to sustainably adopt blended learning, catch up with the elite universities, and bridge the digital divide that is still apparent in South Africa. The paper is based on a review of articles, educational policy documents, and government gazettes. The Atlasti version 8 software was utilised to synthesise the literature. It was concluded that various opportunities exist for rural-based universities. To enhance effective digital transformation in rural-based universities, there is a need for alignment of national policy with realities in different institutions, improve human digital apprehension capacity, and increase collaborations between education technologists and education institutions as well as behavioural change among higher education managers. These changes can enable rural-based universities to build on the opportunities presented by the pandemic and digitalise their education programs to align with the inevitable demands of the 4th industrial revolution.

- Description: The world over, contrasting company performance by firms in the same operating environment and industry has been a conundrum. Firms do not operate in a vacuum, but within spheres where various factors around them affect their performances. To that end, heterogeneous firm performance is a common phenomenon that is influenced by a number of factors, including how management develops appropriate selections, trade-offs and calculated choices to be dissimilar from other players in the market in order to gain a competitive advantage that will lead to superior financial performance. A collection of actions that management puts in place to out-perform competing firms in order to achieve greater profitability is called corporate strategy. These plans of action include the effective management of the socio-political and cultural institutions in a manner beneficial to the organisation. This plan of action on the socio-political and cultural institutions gives rise to institutional strategic management. The formulation of corporate strategies is done through a process that involves a set of rules, ideas or beliefs called frameworks, which include the Resource Based Strategy Framework, Business Models, Innovation and Institutionalism. Research has shown that the financial performance of firms is driven by a number of factors, namely corporate strategy, industry competitiveness, operating environment and core competencies amongst other factors. There is a plethora of determinants for the performance of firms and the complexity in the current business environment that has contributed to some models becoming obsolete while others remain relevant. It is against this background that the primary research objective of establishing a corporate strategy framework used by Zimbabwean firms to increase financial performance was developed. To answer this primary research objective, secondary objectives to (a) determine the impact of the Resource-Based Strategy Framework on the financial performance of firms in Zimbabwe; (b) ascertain the impact of business models using Porter’s Generic Strategies Framework on the financial performance of firms in Zimbabwe; (c) determine the impact of the Institutional Strategy Framework on the financial performance of firms in Zimbabwe; (d) determine the impact of the Innovation Strategy Framework on the financial performance of firms in Zimbabwe; (e) establish the joint impact of the Resource-Based Strategy framework, Business Models, Institutional Strategies and Innovation Strategies on the financial performance of firms in Zimbabwe; and (f) establish other corporate strategy frameworks used by Zimbabwean firms to increase financial performance, were developed. The study population was the Zimbabwe Stock Exchange (ZSE) listed firms that fairly represented all the major operating sectors and firms in Zimbabwe. The researcher adopted a mixed research design incorporating both qualitative and quantitative methods in order to best reflect the critical strategy elements that were increasing financial performance in Zimbabwean firms. Qualitative data was collected through interviews conducted with executive managers of ZSE firms. Triangulation was achieved by comparing and contrasting data collected from interviews to secondary data extracted from websites, reports and audited financial statements. Both qualitative and quantitative data analysis was done using RQDA, an open-source computer-aided data software. ZSE listed firms were categorised into the five sectors of basic materials, consumer goods, consumer services, financial services and industrials. These firms were further categorised into excellent, medium, poor and very poor performers. Collected data was analysed to establish strategies that were used by excellent, medium, poor and very poor firms to see if they were using the same and figure out the impact of the various strategy frameworks on the financial performance on Zimbabwean firms. Data was analysed using univariate, ordinal and binomial logistics regression analysis. These data analysis models confirmed that RBS was a significant driver of financial performance for ZSE listed firms when all the strategy frameworks were combined. However, evaluating the impact of each strategy framework separately showed that all the frameworks were significant in driving financial performance, with the exception of the Institutional Strategy Framework. All the firms were doing more or less the same on Institutional Strategy Framework (ISF), hence it could not be a predictor of financial performance under the regression models. However, the ISF had a high score on univariate evaluation method. It is against this background that the study recommended the use of the Resource Based Strategy Framework (RBS) in pursuit of increasing financial performance of firms as this has been empirically found to have a significant impact on the financial performance of firms in Zimbabwe. , Thesis (DBA) -- Faculty of Business and Economic Sciences, 2021

- Description: Available literature suggests that there is a need to gain more understanding of what students’ environmental attitudes and knowledge are and how they are developed by education systems. Education, in general, plays an important role in students’ attitudes and their knowledge of the world around them. It can shape students’ awareness of their natural environment and contribute to their understanding of environmental issues. Education can also strengthen students’ critical thinking, build awareness, stimulate problem solving, and promote sustainable practices. It has the potential to empower students to address global challenges from their own diverse perspectives and prepare them to uphold the economy. Education can improve and maintain societal wellbeing and can help students to maintain the natural environment, along with achieving sustainable development. Environmental education, specifically, can play a big role in how students deal with the natural environment. The primary aim of this qualitative research study was to examine first-year students’ environmental attitudes and knowledge in the School of Natural Resource Management at the Nelson Mandela University George Campus, South Africa. First-year students’ environmental attitudes and knowledge were examined as they entered the university, and then again at the end of the first semester once they had completed a module in ecology. More specifically, at the outset of the research the objectives were (1) to establish an understanding of the baseline environmental attitudes and knowledge of first-year students who were undertaking three ecological modules being offered by the School of Natural Resource Management; (2) to assess the changes in the first-year students’ environmental attitudes and knowledge, using a post-intervention strategy; (3) to understand what type of teaching approaches were used by the lecturers teaching the ecological modules; and (4) to evaluate how the teaching approaches of the lecturers influenced the baseline environmental attitudes and knowledge of the student group. This research took place in the midst of the Corona Virus pandemic, which had significantly influenced the teaching and learning environment. Multiple education systems, including those of the Nelson Mandela University George Campus, had to rapidly transition to online teaching and learning. So, although unplanned for, this research could not ignore the rapid transition to online teaching and learning and the role it played in shaping the first-year School of Natural Resource Management students’ environmental attitudes and knowledge. It also impacted the teaching approaches of the environmental lecturers. An additional objective in response to the rapid transition to online teaching and learning was, therefore, added: (5) to understand the experiences of the first-year School of Natural Resource Management students and the three environmental lecturers who had to rapidly transition to online teaching and learning. Data was collected via questionnaires and semi-structured interviews with students and staff in the School of Natural Resource Management at Nelson Mandela University George Campus within three different natural resource management programs, namely Agriculture, Nature Conservation, and Forestry. Baseline questionnaires were conducted with 107 students for a baseline assessment as the students entered the university. An online post-intervention questionnaire was conducted with 33 of the initial group of students at the end of the semester for a post-intervention assessment. In-depth semi-structured interviews were conducted with three environmental lectures before they taught their three ecology modules in each of the programs. Additional online semi-structured interviews were also done with the same three environmental lectures after the rapid transition to online teaching and learning took place. The significant findings from this research were analyzed and discussed. This included the baseline environmental attitudes and knowledge of the student body upon arrival at the university and the changes in their environmental attitudes and knowledge after they were exposed to the ecology modules taught in each of the programs. The discussion also included the teaching approaches adopted by the environmental lecturers and the influence their teaching approaches had on the students’ environmental attitudes and knowledge. In addition, the results shed light on the experiences of students and lecturers during the rapid transition to online teaching and learning. The main conclusions reached were that the first-year School of Natural Resource Management students did not have a deep understanding of ecological concepts prior to arriving at university, but they did show a concern for the natural environment. Their lack of understanding was reduced as the students progressed with the ecology module. A greater understanding resulted in a change in students’ perspectives on the ecological module, their program, and the industry they were preparing to enter after being exposed to the ecology module. The environmental lecturers’ teaching approaches contributed to improving the students’ environmental attitudes and knowledge. When it came to the rapid transition to online teaching and learning, both the first-year School of Natural Resource Management students and environmental lecturers experienced benefits and challenges. , Thesis (MSc) -- Faculty of Science, School of Natural Resource Management, 2021

- Description: Third-party logistics (3PL) providers have continued to be key players in the supply chain network and have witnessed a growth in the usage of information technology. This growth has enhanced the volume of structured and unstructured data that is collected at a high velocity, and is of rich variety, sometimes described as “Big Data”. Leaders in the 3PL industry are constantly seeking to effectively and efficiently mature their abilities to exploit this data to gain business value through data-driven decision-making (DDDM). DDDM helps the leaders to reduce the reliance they place on observations and intuition to make crucial business decisions in a volatile business environment. The aim of this research was to develop a prescriptive model for DDDM in 3PLs. The model consists of iterative elements that prescribe guidelines to decision-makers in the 3PL industry on how to adopt DDDM. A literature review of existing theoretical frameworks and models for DDDM was conducted to determine the extent to which they contribute towards DDDM for 3PLs. The Design-Science Research Methodology (DSRM) was followed to address the aim of the research and applied to pragmatically and iteratively develop and evaluate the artefact (the model for DDDM) in the real-world context of a 3PL. The literature findings revealed that the challenges with DDDM in organisations include three main categories of challenges related to data quality, data management, vision and capabilities. Once the challenges with DDDM were established, a prescriptive model was designed and developed for DDDM in 3PLs. Qualitative data was collected from semi-structured interviews to gain an understanding of the problems and possible solutions in the real-world context of 3PLs. An As-Is Analysis in the real-world case 3PL company confirmed the challenges identified in literature, and that data is still used in the 3PL company for descriptive and diagnostic analytics to aid with the decision-making processes. This highlights that there is still room for maturity into using data for predictive and prescriptive analytics that will, in turn, improve the decision-making process. An improved second version of the model was demonstrated to the participants (the targeted users), who had the opportunity to evaluate the model. The findings revealed that the model provided clear guidelines on how to make data-driven decisions and that the feedback loop and the data culture aspects highlighted in the design were some of the important features of the model. Some improvements were suggested by participants. A field study of three data analytics tools was conducted to identify the advantages and disadvantages of each as well as to highlight the status of DDDM at the real-world case 3PL. The limitations of the second version of the model, together with the recommendations from the participants were used to inform the improved and revised third version of the model. , Thesis (MSc) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2021

- Description: Family businesses are the predominant form of business globally and their importance to the economies of countries and job creation are often highlighted. In comparison to non-family businesses, family businesses are often described as having several unique characteristics such as a long-term orientation, being more emotions-laden, and having multiple family generations work in the business. Family businesses are also more deeply rooted in their cultures and values than non-family businesses are, and it is these values that contribute to their uniqueness and longevity. The dominant cultures and values found in family businesses are often associated with those of the founders and their families, and most founders want successive generations to run their family businesses according to established traditions and core values. Despite their importance in both developed and developing economies, family businesses face significant challenges to survive and prosper across generations. One such challenge involves the transmission of values from business founders and/or current leaders to the next generation of family members. If these values are not transmitted to and shared by the next generation, and not entrenched into the functions and processes of their family business, the functioning of the family and the family business are at risk. Existing research on values in family businesses reveals limited knowledge of values transmission to the next generation of family members. In addition, questions remain unanswered as to how values are institutionalised and entrenched into family businesses, and how these values contribute to their longevity and success. Given the need to understand the role of values in the transgenerational success of family businesses, many research calls have been made to investigate the nature of values, values transmission and values entrenchment among family businesses, including those in developing countries. In response to these calls the primary objective of this study was to provide a framework for explaining how values are transmitted among indigenous Black South African business owning families and how these values are entrenched into their family businesses. Investigating values in the context of indigenous Black South African business owning families highlights the influence of indigenous culture on the transmission and entrenchment processes. This study is positioned in the interpretivism and the postmodernism research paradigm. Both deductive and inductive reasoning to theory development and qualitative methodological approach were adopted to create new and richer understandings and interpretations of the phenomena under investigation. Utilising a multiple and descriptive case study methodology, data was collected from seven indigenous Black South African family businesses through semi-structured interviews. To corroborate the interview findings, observations, document analysis and field notes were also used for data collection, which was then analysed utilising reflexive thematic analysis. , Thesis (PhD) -- Faculty of Business and Economic Sciences, 2021

- Description: Riparian vegetation provides an array of various ecosystem functions and has significantly shaped the conditions of catchments. It has strong controls on fluvial geomorphology and erosion processes. The Mgwalana catchment has been intensively studied over the years and the current environmental condition of the study has been linked to land use history. The catchment has been subjected to land use/cover changes (LUCC) over the years. However, spatial variations in riparian vegetation, their implications for stream bank stability and the contribution of land tenure systems to stream channel degradation are poorly understood. The study sought to assess the implications of the spatial variations in riparian vegetation density for stream bank erosion in relation to land tenure on a catchment scale. Land tenure units comprising the catchment of study are traditional and betterment villages (communal lands), and former white commercial farms. A three-pronged approach using GIS and remote sensing, field investigations and laboratory procedures for soil analysis was employed in this study. Variations of riparian vegetation density in the catchment were mapped using ArcGIS for the two land tenure units to assess the spatial variations of riparian density along stream reaches and to determine the spatial relationship between land tenure units and riparian vegetation diminution. Other mapped shape files include sediment accumulation zones to analyse the spatial relationship between riparian vegetation density and sediment sinks. LUCC classification and analysis of the Normalized Difference Vegetation Index (NDVI) were carried out in IDRISI Selva, using Landsat 8 TM imagery of 2018 to represent the current spatial riparian vegetation variations in the catchment. Field investigations were conducted to determine the coupling among hillslope gully erosion, riparian vegetation density and sink areas; and to assess physical characteristics of soil. This would permit an assessment of the implications of riparian vegetation for stream bank erosion and sediment accumulation within the tenure units. Soil samples were taken from scantily and densely vegetated stream reaches, as well as measurements of channel widths and depths. Analyses of soil physical properties viz; grain size distribution, bulk density, soil texture and aggregate stability were done. Results demonstrated that a sparse riparian vegetation distribution was consistent with the communal villages, confined to the upper catchment area. Dense riparian vegetation distribution was consistent with former commercial farms in the lower catchment area. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2021

- Description: This study used a mixed methods approach to provide a systematic review of sustainability reports in South African listed companies that are included in the FTSE/JSE Responsible Investment Index. The purpose was to explore sustainability report content to guide companies of what should be included in such a report. A content analysis schedule was developed to provide the basis for the information to be extracted from the sustainability reports. Three categories, namely, biographical information, reporting format and the theoretical framework were included in the schedule. The sustainability reports of 18 South African JSE SRI Index companies listed on the JSE 2 July 2019 from the mining, retail and investment sectors were included in the sample. The main results showed that the majority of companies in the mining sector used sustainability reports, while nearly half of the companies in the retail sector used sustainability reports. Companies in the investment sector used a variety of reports with a third using integrated reports. Most companies used the JSE listing requirements as their guiding tool in developing their sustainability reports. Environmental issues also seemed to play a major role in sustainability development of a company irrespective of the sector to which it belonged. This systematic review identified the need for a regulator for sustainability reporting and the standardisation of sustainability report content. , Thesis (MCom) -- Faculty of Business and Economic Sciences, 2021

- Description: The concept of a Smart City has evolved over the last three decades and has attracted the increasing interest of the scientific research community. Unfortunately, many Smart City projects and initiatives do not provide the value expected by all the stakeholders. Many of the reasons for this relate to a lack of data management, data integration, data access and stakeholder participation. People are an integral part of any city’s ecosystem, and the Smart City concept was introduced to address the challenges of an ever-growing global population leading to the risk of depletion of economic, environmental and social resources. The problem addressed in this study is based on the challenges preventing the creation of the value of smart cities or stakeholders. Limited research has been published on the status of Smart City initiatives or on the impact of various success factors on the potential value creation for stakeholders including citizens. Studies on initiatives in developing countries, such as South Africa are even less. Whilst some challenges and constraints related to smart cities in Africa have been reported, there are no studies reporting on initiatives across the data value chain that consider all types of stakeholders, nor the impact of these initiatives. This study addressed this gap in research and designed a theoretical Value Alignment Smart City Stakeholder (VASCS) Model based on a Systematic Literature Review and a review of related theories. The model has important components that should form part of any Smart City project or Smart City initiative. These five main components are: 1) nine Smart City dimensions with related success factors; 2) four stakeholder roles (enablers, providers, utilisers and users); 3) the data value chain; and 4) the five phases of stakeholder benefits/value realisation that can be linked to; 5) stakeholder value alignment. This study applied the VASCS Model to Smart City initiatives in two case studies in the Eastern Cape Province of South Africa, which were the Nelson Mandela Bay and Buffalo City to investigate and understand the status of such initiatives and the alignment of value thereof. The stakeholder interviews were conducted in two rounds with various stakeholders of Smart City initiatives, referred to as cases in the two case studies. An expert review of the VASCS Model was conducted with eight experts in the field of Information Systems and Smart Cities. The findings of this review served to confirm the components of the model, with only minor improvements recommended. It was confirmed that all of the components need to be considered in planning Smart City projects. The first round consisted of six interviews with enablers and providers and the second round consisted of 22 interviews with users, utilisers and citizens. The interviews investigated the value and impact experienced by stakeholders of these initiatives, with a particular focus on the users, utilisers and citizens of the cases. The interview data was transcribed and qualitatively analysed by using Atlas.tiand Excel. The data was analysed according to the Technological, Organisational and Environmental theory constructs and other identified themes. The interview analysis findings revealed several drivers for these initiatives, which were primarily cost reduction, integration and quality assurance. The results also highlighted access to resources, such as technical skills as a challenge. Another challenge identified was connectivity related to access to data and the digital and physical divide that can impact decision making. The main benefits of Smart City initiatives highlighted were the provision of infrastructure, education and training and digitalisation. The theoretical contribution of this study is the VASCS Model, which can assist other researchers and practitioners with knowledge of the factors, drivers, challenges and value obtained in Smart City initiatives. The model has two supplementary components: A Stakeholder Classification Model and a Smart City Success Factor Evaluation Template. The practical contribution of this study is the potential use of the VASCS Model by practitioners, city management, researchers and other stakeholders, who can use the model, with the related model and template for planning and evaluating Smart City initiatives. The model can be used to classify the digital activities according to a Smart City’s success factors while evaluating the value created by these activities. The impact of these initiatives can then be assessed through value realisation and alignment for stakeholders. The scientific contribution is the adoption of the model to the cases in the Eastern Cape. To reveal in depth, rich, interview findings that provide important lessons learnt relating to the value created for the stakeholders and the addition of these findings to the body of knowledge. , Thesis (PhD) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2021

- Description: Housing delivery in South Africa is a crucial and topical issue affecting many citizens. The primary objective of the study was to determine the role of administrative justice in the implementation of the Reconstructive and Development Programme (RDP) in Berlin Town, in the province of the Eastern Cape in South Africa. In addition, the aim of this study was to explore the challenges of RDP housing in the study area, as a way of probing whether housing needs were being met. The study was conducted using a qualitative research methodology in gathering data from Berlin Town residents, Buffalo City Metropolitan Municipality staff and Berlin Town councillors. The data analysis revealed that respondents affirmed the importance of administrative justice and the effective implementation of the RDP with regard to housing. Based on the findings of the study, the researcher recommends that the Buffalo City Metropolitan Municipality prioritise the full implementation of the Integrated Development Plan (IDP) in dealing with the housing backlog and challenges in Berlin Town. Moreover, the findings of this study revealed that it is possible to highlight specific recommendations that can be used by various other local municipalities. Thus, the research study showed that efficient local municipal operations have a direct impact on the delivery of RDP houses. Relating to ethical considerations, the researcher ensured that all the requirements for credible research were met throughout the study. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2021

- Description: Businesses are under threat and will need to continuously improve if they are to survive, compete successfully and grow in the global marketplace. This is particularly the case for the manufacturing sector where continuous improvement in the quest to become efficient is of utmost importance. Lean Manufacturing (LM) has been implemented globally and has proven itself to be a benchmark manufacturing practice for achieving continuous improvement directed at business success with respect to increase revenue and business growth. Within the South African manufacturing industry, especially amongst automotive manufacturing sector, Lean Manufacturing has been widely implemented with mixed success. As Lean Manufacturing affects both processes and people, lean principles become key contributors for successful implementation within manufacturing. This study aimed to identify key principles required to improve the success of Lean Manufacturing implementation in the local manufacturing industry in South Africa. The research conducted identified pertinent aspects of LM that could be applied within the SA context. It begins with a review of current literature on Lean Manufacturing, exploring several topics which are relevant to the study. Lean Manufacturing literature was then summarised and tabulated into the Principles and supportive behavioural elements for successful Lean implementation. Important aspects identified during the research that are required for successful LM implementation were Teamwork, Engagement / Commitment, Ideas / Suggestions, Communication, Improvement Culture, Training and Committed Leadership. Then, a literature review on African Leadership was conducted, exploring various elements of leadership and principles that are instilled in leaders within Africa. Key elements from this literature were summarised and tabulated into the Principles and supportive behavioural elements within African Leadership. For African Leadership, principles such as Communalism, Collectivism, Humaneness, Mutual Respect and Cross Cultural Literacy were identified as Uniquely African Traditional Leadership Principles required to be present for successful Lean implementation. These summaries formed the basis from which two self-constructed questionnaires and a Uniquely African Traditional Leadership Principles Interview were compiled. The two self-constructed questionnaires and interview were used as measuring instruments to measure the presence of the above mentioned principles and behavioural elements within organisations and determine whether they have an impact on the sustainability of Lean Manufacturing implementation. Finding from this research indicated that the Uniquely African Traditional Leadership Principles identified were present within organisations, but to an even greater extent within organisations that have successfully implemented Lean Manufacturing. This indicates that Uniquely African Traditional Leadership Principles have a positive effect on the sustainability of Lean Manufacturing implementation. The researcher recommends that, to further improve the presence of Uniquely African Traditional Leadership Principles and principles that display successful LI within organisations, focus be placed on the principles and supportive behavioural elements detailed within this document. , Thesis (DBA) -- Faculty of Business and Economic Sciences, 2021

- Description: Businesses are under threat and will need to continuously improve if they are to survive, compete successfully and grow in the global marketplace. This is particularly the case for the manufacturing sector where continuous improvement in the quest to become efficient is of utmost importance. Lean Manufacturing (LM) has been implemented globally and has proven itself to be a benchmark manufacturing practice for achieving continuous improvement directed at business success with respect to increase revenue and business growth. Within the South African manufacturing industry, especially amongst automotive manufacturing sector, Lean Manufacturing has been widely implemented with mixed success. As Lean Manufacturing affects both processes and people, lean principles become key contributors for successful implementation within manufacturing. This study aimed to identify key principles required to improve the success of Lean Manufacturing implementation in the local manufacturing industry in South Africa. The research conducted identified pertinent aspects of LM that could be applied within the SA context. It begins with a review of current literature on Lean Manufacturing, exploring several topics which are relevant to the study. Lean Manufacturing literature was then summarised and tabulated into the Principles and supportive behavioural elements for successful Lean implementation. Important aspects identified during the research that are required for successful LM implementation were Teamwork, Engagement / Commitment, Ideas / Suggestions, Communication, Improvement Culture, Training and Committed Leadership. Then, a literature review on African Leadership was conducted, exploring various elements of leadership and principles that are instilled in leaders within Africa.

- Description: The role that is played by Non-Governmental Organisations in aiding development initiatives can never be overemphasised. These organisations have partnered with numerous States, mostly in developing countries, in spearheading, facilitating, and evaluating various development programmes. Yet, they face daunting futures as their constant reliability on donor funds has affected their sustainability. To this end, their efforts in addressing social, economic, and even political challenges in a sustainable manner is greatly compromised. This research seeks to assess the financial sustainability of local NGOs with Thandusana as a case study. It further explores factors other than funding that influences an organisation's financial sustainability. These factors are income diversification, sound financial management practices, good donor relationships and own income generation. The research concurred with many other scholars that local non-governmental organisations in South Africa are financially unsustainable and are dependent on donor funds, and Thandusana is no exception. After having found out that Thandusana is not geared to create its own income-generating activities, the research concludes by recommending that the governing board establish structures that commit funds for profit-making ventures which are in turn used to sponsor their non-profit functions but caution should be exercised lest they abandon their missions for profit-making. This study employed a qualitative research approach and is based on an interpretive paradigm. The research used a descriptive case study design. Data was collected using document compilation while document analysis was the data analysis tool. Non-probability sampling was used in selecting the sample that was used. , Thesis (MADS) -- Faculty of Business and Economic Sciences, 2021

- Description: In recent years, the concept of entrepreneurial ecosystems increased in status amongst policy makers, scholars, practitioners, and mainstream media as a regional economic development strategy. Yet, despite the opportunities presented by the entrepreneurial ecosystem, it is both under-theorized and lacks data on a sub-national scale. Furthermore, research from an African and sub-Saharan African context remains in its infancy. The limited research within these resource-constrained countries creates a challenge to determine the underlying factors that influence entrepreneurship. As a result, developing economies, as in the case of sub-Saharan Africa, have applied generalizations of the entrepreneurial ecosystem, which undermine the temporal differences of places and reduce the potential to benefit from agglomeration economies. With the National Development Plan: Vision 2030, the South African government strives to achieve an inclusive economy through enhancing the capacity of the state, building capabilities, and promoting partnerships amongst sectors. Motivated by the mandate to redress the inequality caused by economic exclusion, the South African government has taken counteractive measures focused on promoting entrepreneurship as a key driver of economic growth. Despite the measures placed, South Africa struggles with high levels of inequality with a Gini coefficient of 0.63, unemployment of 32.6% and negative GDP per capita growth of - 8.137%. Furthermore, most small businesses in South Africa are informal, which means that a disproportionate concentration of employment exists in the informal sector. Against this backdrop, the problem addressed in this study is based on the challenge of creating productive entrepreneurship that acknowledges the unique structure and resources of Nelson Mandela Bay. To address this gap, a critical inquiry into entrepreneurial ecosystems was motivated. First, the inquiry is focused on a real-world context, namely Nelson Mandela Bay, which is one of the eight metropolitan regions in South Africa, a developing economy. Second, the inquiry uses multiple perspectives through multiple data collection methods. To commence the inquiry, a literature review was conducted on secondary sources to identify the factors influencing entrepreneurial ecosystems and formed the basis of the theoretical framework. The study followed the pragmatism research philosophy and used an abductive research approach. A mixed method research design was utilized and followed a sequential independent process, which was performed in two phases and independently analyzed. , Thesis (DBA) -- Faculty of Business and Economic Sciences, 2021

- Description: Ocean health provides the foundation for human health through the provisioning of ecosystem services. Increasing demands on ocean space and resources are, however, resulting in a decline in ocean health, with direct and indirect knock-on effects on marine uses and ultimately on human health. In response, there is a growing need to acknowledge and better manage complex human-ocean interactions. This has been recognised in global sustainable development goals and in integrated ocean management processes, leading to widespread endorsement of an ecosystem-based marine spatial planning (MSP) process, including in South Africa. In support of the national MSP process, significant progress has been made in understanding the spatial extent of marine activities and associated marine pressures, but the temporal dynamics of marine activities and interconnections with the marine environment are less well understood. To plan for the growth of marine activities and associated user conflicts, the drivers of these temporal dynamics and associated feedback effects need to be analysed and potential policy and management interventions identified and tested. To support South Africa’s national MSP process, this study adopts a systems analysis approach, using system dynamics modelling, to explore the temporal change in marine uses under alternative growth scenarios in Algoa Bay. Algoa Bay is an appropriate study area because it is experiencing a rapid expansion of marine activities, coupled with a growing uncertainty regarding marine sustainability outcomes. To assist future marine management decisions, the Algoa Marine Systems Analysis Tool (Algoa MSAT) was developed, comprising seven sub-models. Five of the sub-models represent selected marine uses in Algoa Bay, whereas the sixth and seventh integrate the outputs from each marine use in terms of sustainable management indicators (marine health, marine wealth and marine labour). Model development primarily adopted an expert-based model ling approach, although the involvement of stakeholders, through a collaborative modelling process, assisted in integrating knowledge on different marine sectors’ activities, impacts and planning visions into the model framework. Model results were generated under different scenarios to investigate changes in the growth of marine activities and marine sustainability indicators under different levels of ocean governance. Under the baseline (or business-as-usual) model scenario, marine activities were shown to grow increasingly within their respective management limits, with an increase in marine wealth and labour and a consequential decrease in marine health. This scenario particularly highlights that current ocean governance practices are ineffective in sustaining the projected growth of the marine uses, particularly for those that are vulnerable to negative changes in marine health. Conversely, sectors that hold more value in marine wealth and are more resilient to changes in marine health, may continue to grow regardless of negative knock-on effects of the health of the marine environment and on other uses in the bay. This emphasises that an alternative governance strategy is needed to achieve the long-term goal of an ecosystem-based MSP process, as required by South African MSP legislation. To achieve this will require multiple, adaptive cross-sectoral management interventions that are directed towards the ‘deeper leverage points’ that are able to maintain the growth of marine activities within appropriate limits defined by marine health. Using the model interface developed in this project, decision-makers and stakeholders can use the model to explore the temporal dynamics in marine activities under different governance scenarios. Although the model is limited to Algoa Bay, the model boundary can be adapted to assist in marine planning processes at national or trans-national scales. Such analytical assessments and tools are critical to progress the ecosystem-based management approach in MSP, as is required to achieve global sustainable development goals. , Thesis (PhD) -- Faculty of Science, Coastal and Marine Research Unit, 2021

- Description: Web-based technologies have fostered an online environment where information can be disseminated in a fast and cost-effective manner whilst targeting large and diverse audiences. Unfortunately, the rise and evolution of web-based technologies have also created an environment where false information, commonly referred to as “fake news”, spreads rapidly. The effects of this spread can be catastrophic. Finding solutions to the problem of fake news is complicated for a myriad of reasons, such as: what is defined as fake news, the lack of quality datasets available to researchers, the topics covered in such data, and the fact that datasets exist in a variety of languages. The effects of false information dissemination can result in reputational damage, financial damage to affected brands, and ultimately, misinformed online news readers who can make misinformed decisions. The objective of the study is to propose a set of guidelines that can be used by other system developers to implement misinformation detection tools and systems. The guidelines are constructed using findings from the experimentation phase of the project and information uncovered in the literature review conducted as part of the study. A selection of machine and deep learning approaches are examined to test the applicability of cues that could separate fake online articles from real online news articles. Key performance metrics such as precision, recall, accuracy, F1-score, and ROC are used to measure the performance of the selected machine learning and deep learning models. To demonstrate the practicality of the guidelines and allow for reproducibility of the research, each guideline provides background information relating to the identified problem, a solution to the problem through pseudocode, code excerpts using the Python programming language, and points of consideration that may assist with the implementation. , Thesis (MA) --Faculty of Engineering, the Built Environment, and Technology, 2021

- Description: Corporate governance is regarded as a system by which an organisation is directed and controlled and it is concerned with structures and responsibilities within organisations. Public entities’ corporate governance is a concept that is gaining more interest, both in specialized literature and in practice. Corporate governance practices are not standard across countries and this dissimilarity is a result of diverse legal structures and cultural settings adopted by different states and provinces. The Eastern Cape Public Entities (ECPEs) have an important role to play in pursuing the economic, social and developmental state agenda. The EC province has ten (10) public entities with mandates and enabling legislations to enhance the provincial economic development, growth and sustainability issues. Of the ten (10) public entities, one entity was used for pilot study. Furthermore, one public entity decided to withdraw from the study, as it was voluntary to participate and that resulted in eight public entities participating. In terms of the questionnaire returns, forty-four (44) responses were received from eight (8) public entities. The main objective of this study was to investigate selected factors impacting on effective corporate governance of ECPEs. In this study, positivistic research paradigm was utilised by means of quantitative research method. Non-probability sampling was used. Primary data was collected using the survey method by means of structured self-administered questionnaires. The empirical results showed that ethical value, organisational culture and policy regulatory framework had a statistically significant impact on corporate governance of ECPEs; while employee morale, leadership, and role clarification were found not to have a statistically significant impact on corporate governance. The findings of this study are envisaged to assist in ensuring effective governance of public entities in order to encourage accountability, public confidence or trust in the corporate system and to drive public policy. Furthermore, the findings can help public entities to achieve what is expected, in terms of work performance objectives or productivity in accordance with the norms and standards. , Thesis (MCom) -- Faculty of Business and Economic Sciences, 2021

- Description: Environmental Education (EE) is essential for addressing environmental challenges.The advantages of EE are undeniable; it might be used to address specific environmental concerns and their implications, as well as to modify behaviours that lead to environmental catastrophes.EE strengthens people's resilience to climaterelated hazards. Global environmental issues have heightened interest in educational policy outcomes and their implications for economic growth and social citizenship. It is worth noting that an effective EE policy has a significant influence on the development of learners' environmental literacy. This study assessed the implementation of environmental education school policy in the Buffalo City Metro Education District, South Africa. This study adopted the pragmatism paradigm of Mixed Method Research(MMR). Concurrent triangulation, which is a design that employs a single data collection technique in which quantitative and qualitative data gathering and analysis are carried out independently yet concurrently, was used for this study. The target population of this study involved 60,412 teachers, 1,770,289 learners in 5205 public schools, and 1 Pro-EE civil society organisation in the Eastern Cape province. This was narrowed down to over 268 public and independent schools, teachers, and principals within the enclave of the Buffalo Metropolitan education district. The study adopted stratified purposeful and simple random probability sampling. In this technique, the sampling frame of the study was divided into strata or groups (principals, teachers, learners, and CSOs) and a sample was purposefully selected from each stratum (Migiro & Magangi, 2011). The stratified purposeful random sampling techniques draw data from 10 principals, 175 teachers, 1500 learners, and 1 CSO. Structured questionnaire; Implementation of EE Policy Questionnaire (IEEPQ) whose reliability co-efficient value using Cronbach Alpha was 0.74, semi-structured interview and documents were the instruments used to collect data for this study. The data were analysed using descriptive statistics of percentage, mean, and standard deviation for the quantitative data while the thematic approach of sorting, coding, transcribing, and categorization was used for the qualitative data. The study revealed the following. When asked whether teachers had studied environmental education in tertiary institutions as part of their professional training, the majority of the teachers'respondents, 108, representing 61.7percent, disagreed with this view. On the flip side, a handful of teachers 67, (38.3percent) agreed with the view of having had some sort of EE knowledge during their professional training as teachers. With regards to the view that learners learn environmental issues through other subjects, most of the learner respondents, 1316 representing 87.7percent, agreed with this view. On the contrary, a minority of the respondents 184 (12,3percent) had a dissenting opinion. This indicates that most learners in school learn about environmental concerns through other traditional subjects. The study established that EE content is manifest in teachers' and learners' textbooks, teaching methods, and co-curricular activities. However, the study identified lapses in how teachers and learners integrate EE into their day-to-day practices. Therefore, the implementation of the EE policy seems to be an exercise in futility. The absence of a policy guideline document has made teachers and school administrators incapacitated in the implementation of EE school policy. , Thesis (PhD) -- Faculty of Education, 2022

- Description: Environmental Education (EE) is essential for addressing environmental challenges.The advantages of EE are undeniable; it might be used to address specific environmental concerns and their implications, as well as to modify behaviours that lead to environmental catastrophes.EE strengthens people's resilience to climaterelated hazards. Global environmental issues have heightened interest in educational policy outcomes and their implications for economic growth and social citizenship. It is worth noting that an effective EE policy has a significant influence on the development of learners' environmental literacy. This study assessed the implementation of environmental education school policy in the Buffalo City Metro Education District, South Africa. This study adopted the pragmatism paradigm of Mixed Method Research(MMR). Concurrent triangulation, which is a design that employs a single data collection technique in which quantitative and qualitative data gathering and analysis are carried out independently yet concurrently, was used for this study. The target population of this study involved 60,412 teachers, 1,770,289 learners in 5205 public schools, and 1 Pro-EE civil society organisation in the Eastern Cape province. This was narrowed down to over 268 public and independent schools, teachers, and principals within the enclave of the Buffalo Metropolitan education district. The study adopted stratified purposeful and simple random probability sampling. In this technique, the sampling frame of the study was divided into strata or groups (principals, teachers, learners, and CSOs) and a sample was purposefully selected from each stratum (Migiro & Magangi, 2011). The stratified purposeful random sampling techniques draw data from 10 principals, 175 teachers, 1500 learners, and 1 CSO. Structured questionnaire; Implementation of EE Policy Questionnaire (IEEPQ) whose reliability co-efficient value using Cronbach Alpha was 0.74, semi-structured interview and documents were the instruments used to collect data for this study. The data were analysed using descriptive statistics of percentage, mean, and standard deviation for the quantitative data while the thematic approach of sorting, coding, transcribing, and categorization was used for the qualitative data. The study revealed the following. When asked whether teachers had studied environmental education in tertiary institutions as part of their professional training, the majority of the teachers'respondents, 108, representing 61.7percent, disagreed with this view. On the flip side, a handful of teachers 67, (38.3percent) agreed with the view of having had some sort of EE knowledge during their professional training as teachers.
