- Description: The Head of Department (HOD) position at a university has traditionally been viewed as an individual construct. However, due to the demanding nature of such a position, it is not sought-after, as it remains exclusive and unappealing to many academics. Moreover, it is a position that does not encourage inclusive leadership. Tension and role ambiguity are known to arise between the scholarly project on the one hand and management and administrative matters on the other. To address challenges associated with this singular leadership position, an academic department at a South African university adopted a distributed leadership approach in their department as a research experiment. My study was based on this research experiment. I designed this research as an exploratory case study, guided by a socio-cultural conceptualisation of distributed leadership that included a leader-plus and a practice aspect, defined as a product of the interactions of school leaders, followers and their situation. This qualitative case study aimed to describe and explain how a distributed leadership approach was understood and practised in an academic department. It also investigated the enablements and constraints of the approach. Data were generated through document analysis, observation, and individual and focus group interviews. The participants in this study included the departmental leadership team and the department’s academic and administrative staff. Unfortunately, my study took place during the global COVID-19 pandemic and national lockdowns. I had no choice but to adapt my data generation methods due to lockdown restrictions. As a result, most data generation was done via online communication. The study used inductive and abductive analysis to make the data meaningful to the reader. The findings revealed that different participants had different ideas about distributed leadership. Distributed leadership was understood as a socio-cultural practice rather than an individual practice with multiple leaders in relational practice. In addition, this approach was understood as a way of developing and sharing expertise by encouraging teamwork, collegiality and collective decision-making which aligns with the notion of democratic decision-making which creates a platform for the enablement of leadership in others. The study further explored how distributed leadership was practised. The findings were that the HOD position, usually a one-person role, was reconceptualised as a HOD team comprised of three academics and the departmental administrator. The HOD team divided the work among themselves, and this was done according to each individual’s expertise. In addition, leadership within the academic department was not limited to the HOD team but stretched across the department; thus, multiple leaders were evident. Therefore, based on the data, this study discovered that a distributed approach values leadership expertise in others. Consequently, it can be used to promote an inclusive environment in which any organisation member can lead. Inclusivity in the decision-making process was also regarded as a strong practice in the academic department. As a result, this study contends that those in formal positions can develop leadership in others through a distributed leadership approach. Through that, lecturer leadership was enacted through formal faculty and university structures and informally as and when the situation required it. The enablements of this departmental leadership approach included the structural innovation of the Friday check-in as well as the buddy system. These two innovations provided the space for collegiality and the development of voice and leadership. The consultative nature of the HOD team was also viewed as an enablement. Certain factors constrained the distributed leadership approach, one of which was the tension between the hierarchical structure of the university and the more horizontal, distributed leadership approach being piloted in the academic department. In addition to that, another constraint was also very real with the transition to Zoom as an online teaching, learning and supervision platform as a consequence of the COVID-19 pandemic. The final constraint was experienced concerning the department’s history, as it was within a historically White university in South Africa. The effects of this history impacted the departmental culture and, as we know from the literature, institutional culture is extremely difficult to change. Finally, the study concluded that conceptualising distributed leadership as a sociocultural practice with leader-plus and practice aspects provides descriptive language and a solid theoretical and analytical framework for a distributed leadership study. The study makes an important knowledge contribution in the African Higher Education context as limited research has been carried out in this area. Furthermore, in terms of practice, my study serves as a stimulus for leadership discussions that are beneficial to everyone involved in educational institutions as they promote a level of leadership reflexivity, currently absent in many institutions. , Thesis (MEd) -- Faculty of Education, Secondary and Post-School Education, 2023

Corporate failure and ethical resources: a case study of Steinhoff and Carillion

- Description: This study aimed to investigate the impact of disregarding ethical resources on company performance, with a particular focus on Carillion and Steinhoff as case studies. A pragmatist research philosophy was employed using a mixed methods approach, utilizing deductive inferencing to produce archival research. Data was collected from annual financial statements and existing literature on Steinhoff and Carillion's corporate failures. Both content analysis and statistical analysis were employed to analyse the data. The study found that both Carillion and Steinhoff were at the top of their respective industries when they began to underperform due to poor governance. On the part of Carillion, much of its failure can be attributed to aggressive bidding, while for Steinhoff, its failure was due to unscrupulous accounting practices. Corruption and fraud at the top echelon of each of these respective companies began to trickle down to the bottom of the hierarchy. Additionally, Steinhoff used a two-tier board system that promotes information asymmetry between a management board and a supervisory board. This gave Steinhoff’s management board leverage to manipulate company reports and hide information from the supervisory board. Steinhoff equally violated the board’s independence by making former management executives part of the supervisory board, who could potentially be lenient to the management board due to past relationships. This was further exacerbated by the CEO duality, which contributed to Steinhoff’s lack of board independence. Furthermore, Steinhoff’s board was reported to have served as board members for a long time, eventually leading them to create a group culture that negatively affected its board’s independence. Different from Steinhoff, which lacked board independence and board diversity, at face value, Carillion appeared to have a predominantly independent board with diverse experience and external commitments. However, Carillion also lacked board independence in a different way, as some of its board members were previously employed by KPMG. KPMG was also the external auditor of Carillion. This created a scenario where Carillion and KPMG were conniving, which may have affected the objectivity of the external audits on financial performance. Further to this, the CEO held outsized power over the board, which could have also resulted in a lack of independence. This, in turn, facilitated corrupt behaviour within the organisation, which may have contributed to its corporate failure. iv The findings of the study highlight the following three conclusions: i) profits that are premised on reckless, irregular, and fraudulent business and accounting practices are not sustainable; ii) governance structures that do not adhere to sound corporate governance principles result in impaired board independence and negatively affect firm performance; and iii) companies that reach the pinnacle of their success through unethical conduct are ultimately short-lived. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2023

- Description: Marital satisfaction may be described as the extent to which one’s expectations, desires and needs are being satisfied in their marriage. Studies that concern marital satisfaction provide us with crucial insights into factors that support or compromise the longevity of long-term, committed relationships. Little work has been done in understanding the role of cultural practices in marital satisfaction particularly in Africa, and South Africa more specifically. Ukuyalwa is a Xhosa ritual that takes place during a Xhosa traditional wedding, whereby the bride is introduced to the (traditional) guiding practices of her new home by the women of the family together with her sisters-in-law. This study informs the practice of African psychology as formulated by Ratele (2017b).Critical African psychology as a framework recognizes the construction of culture alongside political, socioeconomic, and historical matrices. These are acknowledged as an important element in psychological theories, methods, and explanations. This research project aimed to identify the discourses that circulate around ukuyalwa as a Xhosa cultural practice and consider the implications for the marital satisfaction of amaXhosa couples. The study interviewed 3 Xhosa couples of varying ages who had been married for different durations to develop an understanding of their experiences of ukuyalwa and marital satisfaction. Data was analyzed using a Foucauldian Discourse Analysis (FDA) which allowed for the identifications of the discourses that the couples used to construct ukuyalwa and marital satisfaction. The couples discursively constructed marriage as ‘divine unity’, ‘unification of families’ and ‘partnership’. Ukuyalwa was constructed as a ‘gendered process’, ideas of tradition and modernity, and a ‘foundation’ also became apparent. Satisfaction was constructed as ‘open communication’ and ‘work’. The couples’ positions shifted in their conversations, where in some instances they were 'learners’, ‘initiates’, and/or ‘passive’, and in other instances, they were ‘in charge’, ‘knowledgeable’, and ‘experts’. The discourses of culture, religion, and partnership circulated prominently in relation to marriage, ukuyalwa, and marital satisfaction. The findings of the study speak to how the couples’ constructions of marriage and cultural customs such as ukuyalwa are valuable as they often inform how couples behave in their marriage relationships and what they regard as satisfactory to them when it comes to marriage. These insights into what informs the couples’ ideas on marriage and satisfaction can be utilised in informing couples therapy interventions. , Thesis (MA) -- Faculty of Humanities, Psychology, 2023

- Description: The foundation of the South African narrative is framed by identity politics; a politics instituted at the intersection of race and class to exclude all people considered non-White concerning the socioeconomic and political landscape of the country. The preamble of the Freedom Charter signed in 1955 declared that the country belongs to all who live in it: Black and White people. The dominant constructivist narratives of addressing the racial dichotomy obliterate the injustice suffered by the Khoe-San people whose identity was overshadowed under the homogeneous term, Coloured people. Following the first democratic elections, at the negotiations of the Convention for a Democratic South Africa (CODESA) in 1996, Khoe-San people were once again excluded and played no significant role in deciding the future of the new South Africa. The epistemic injustice suffered by the Khoe-San people, the loss of land, language, and cultural heritage were glanced over in the new democratic dispensation. In this thesis, I hone into the identity politics and identity formation of the Khoe-San people, after 1994. The self-identifying Khoe-San people became visible to the democratic state through various forms of activism and networking across provinces foregrounding the concept of indigeneity to address issues of exclusion and marginalisation. The phenomenon of indigeneity, bestowed on Khoe-San people by the United Nations Declaration on the Rights of Indigenous People (UNDRIP) created a path for the Khoe-San people to be in conversation with state organs to address their plight of the loss of land linked to identity, language, culture, heritage, and other social ills experienced in their communities. The thesis illustrates the vagueness of Coloured identity under the Apartheid state, and the preconceived narrative that Coloured people were a privileged group; precludes and obliterates the epistemic injustice suffered by Khoe-San people. The transnational conceptualisation and global politics of indigenous peoples; the particularity of indigeneity in relation to First Nation Status, in the South African context, destabilises identity politics and the four-tier racial categorisation system used by the Apartheid state carried through by the national government under democracy. The conceptualisation of this global discourse on indigeneity brought a new consciousness in sections of the Coloured community where self-identifying Khoe-San people question their place in the democratic dispensation. , Thesis (PhD) -- Faculty of Humanities, Anthropology, 2023

- Description: Learning to read for meaning and enjoyment in the Junior Primary phase is an essential goal for every child during their primary schooling. Despite this, reading for meaning and enjoyment in the Namibian context, specifically for primary learners, remains a concern. Current research suggests that there are very few studies that have been done in Namibia that examine the pedagogical practices of Junior Primary teachers to develop learners’ reading competence. In view of that, this study focused on the pedagogical practices of Junior Primary teachers in mediating reading in their classrooms. The study is a qualitative interpretive case study using observation and interviews as tools to generate in-depth data on how teachers teach reading. The study sample comprised of three Junior Primary teachers from Grades 1-3 who participated in this study. The selection criteria were based on historical background and the culture of teaching reading lessons for Grade 1-3 teachers. The study revealed some factors that impede the teaching of reading. Amongst them are a lack of in-service training, language barriers, and the lack of resources. The study found that English used as the LoLT (Language of Learning and Teaching) at the school where the study took place made it difficult for the teachers to convey the correct information to the learners due to a lack of proficiency. The study revealed that this situation limited most of the learners’ reading opportunities. Theory of Practice Architecture (ToPA), in particular by Kemmis and Grootenboer (2008), was used as an explanatory and analytical tool. This research asked the questions: 1.What pedagogical practices do Junior Primary teachers employ to mediate reading? and 2. What factors enable and constrain the pedagogical practices of teachers? As a way forward, this study recommends for a compulsory reading program be instituted at Higher Education Institutions responsible for teacher education. This should empower the teachers to enter a Junior Primary classroom with more confidence to teach the various reading components. This study recommends continuous in-service courses for teachers. The study further recommends that the Ministry of Education, Arts and Culture make provisions for textbooks in all schools for all learners if the learners reading performance is to improve in Namibia. , Thesis (MEd) -- Faculty of Education, Education, 2023

- Description: Microbial communities of bacteria, viruses, algae, protozoans and fungi participate profoundly in aquatic systems, particularly in mediating processes such as primary production, decomposition, and biogeochemical cycles. In addition, microbiomes produce extracellular polymeric substances (EPS) which encompass a hydrated exopolymer mainly constituted of carbohydrates and proteins. The exopolymer aid proliferation and persistence of biofilms on their resident surfaces. There is however paucity of data on functional diversity of microbiomes in arid zone temporary wetlands with previous research having mainly focused on permanent systems in the northern hemisphere. In the face of ongoing climatic changes and anthropogenic threats to wetlands, it is imperative to assess the health status of aquatic systems in relation to microbial productivity dynamics. In this thesis, colorimetric methods and sequence–based metagenomics were conducted to quantify microbial EPS production and bacterial metagenome functions, respectively. This study was conducted in Khakhea–Bray region (North–West, South Africa) in June 2021 and January 2022 with a focus on evaluating microbial patterns of distribution between seasons (i.e., Dry and Wet) and varying depth i.e., deepest zones (Deep), intermediate depth (Mid) and shallowest regions (Edge). Additionally, potential relationships between EPS and either water content or organic matter content (OM content) were evaluated. In this study it was hypothesized that wet phases and deeper zones will have high EPS production and support more functions in comparison to shallowest regions and dry phases. Carbohydrates and proteins were quantified using the Dubois method and modified Lowry procedure, respectively. Carbohydrates generally occurred in higher proportions than proteins, suggesting that EPS found in these systems was largely diatom produced. The wet phases (wet season and inundation periods) supported more EPS production compared to the dry phases. The results of principal components analysis (PCA) and Spearman’s correlations suggested that EPS was highly correlated with sediment water content among other assessed variables. No significant associations were established between EPS and organic matter content. Spatial distribution of EPS demonstrated similar patterns between the deepest (Deep) and the intermediate depth zones (Mid) however the shallow regions (Edge) had significantly lower concentrations. Bacterial characterization was established by amplification of the 16S rRNA gene using illumina–sequencing protocol. Enzyme functions associated with biogeochemical pathways were predicted in PICRUSt2 bioinformatics pipeline. A total of 15 042 Unique Amplicon Sequence Variants (ASVs) were observed to be affiliated to 51 bacterial phyla and 1 127 genera. All top genera had commonality in heat tolerance. Firmicutes, dominated at phyla level with 59 % (mean ± sd, 19 ± 13 %) relative abundance followed by Actinobacteria and Proteobacteria both at 34 % (18 ± 7 %) and (18 ± 6 %), respectively. Microbial diversity matrices highlighted significant differences in beta diversity more than alpha diversity. Bacterial microbiomes were more distinct between seasons compared to within season, suggesting that functions were seasonally driven. These findings were supported by highest rates of denitrification, carbohydrate degradation and EPS production by core microbiomes in the wet season as compared to low rates of nitrogen mineralisation, carbon fixation and nitrification in the dry season. The present findings represent a first attempt in evaluating sequence–based metagenomics in semi–arid southern African temporary pan ecosystem. Both microbial EPS and bacterial functional potential were highly driven by water availability, with highest rates mainly associated with maximum inundation compared to dry states of pans. It can therefore be suggested that extended dry periods are threatening to microbially mediated processes in temporary wetlands, with implications to loss of biodiversity due to desiccation resulting in poor nutrient cycling. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2023

- Description: Microbial communities of bacteria, viruses, algae, protozoans and fungi participate profoundly in aquatic systems, particularly in mediating processes such as primary production, decomposition, and biogeochemical cycles. In addition, microbiomes produce extracellular polymeric substances (EPS) which encompass a hydrated exopolymer mainly constituted of carbohydrates and proteins. The exopolymer aid proliferation and persistence of biofilms on their resident surfaces. There is however paucity of data on functional diversity of microbiomes in arid zone temporary wetlands with previous research having mainly focused on permanent systems in the northern hemisphere. In the face of ongoing climatic changes and anthropogenic threats to wetlands, it is imperative to assess the health status of aquatic systems in relation to microbial productivity dynamics. In this thesis, colorimetric methods and sequence–based metagenomics were conducted to quantify microbial EPS production and bacterial metagenome functions, respectively.

- Description: This thesis reports on the synthesis, characterization, photophysiochemical properties of morpholine substituted symmetrical and asymmetrical porphyrins. The synthesized porphyrins are conjugated to cancer selective biomolecules (folic acid and biotin) which are linked to nitrogen doped graphene quantum dots, as potential photosensitizers for photodynamic therapy (PDT). The symmetrical morpholine porphyrin complexes 2 (Sn(IV) 5,10,15,20 tetra-4-morpholinyl porphyrin) and 3 (Zn 5,10,15,20 tetra-4-morpholinyl porphyrin) had the same substituent but different central metals, and they were both conjugated to biotin decorated nitrogen doped graphene quantum dots (B-NGQDs), however complex 2 (Sn(IV) 5,10,15,20 tetra-4-morpholinyl porphyrin) was conjugated to B-NGQDs through an ester bond and complex 3 (Zinc 5,10,15,20 tetra-4-morpholinyl porphyrin) through 𝜋-𝜋 stacking. The effect of asymmetry was studied by comparing complex 3 (Zn 5,10,15,20 tetra-4-morpholinyl porphyrin) and complex 5 (Zn 5- bromophenyl-10-15-20-(tris-4- morpholinyl) porphyrin). Complex 5 (Zn 5- bromophenyl-10-15-20-(tris-4- morpholinyl) porphyrin) was an asymmetric porphyrin with morpholine and bromine as substituents. It was observed that asymmetry enhances singlet oxygen quantum yield and PDT activity. It was also observed that folic acid is a better targeting biomolecule when compared to biotin, and this was studied by comparing complex 3 conjugated to B-NGQDs and complex 3 conjugated to folic acid decorated nitrogen doped graphene quantum dots (FA-NGQDs). 3-FA-NGQDs had a better cellular uptake and PDT activity. , Thesis (MSc) -- Faculty of Science, Chemistry, 2023

- Description: Mathematics is a language that is rich in visual representations (Mudaly & Rampersad, 2010). Visual Representations assist us in developing our reasoning skills when solving a problem and our understanding of the relationships between concepts (Ozkan et al., 2018). This thesis focuses on the different visual representations (VR) in South African Foundation Phase mathematics textbooks and workbooks. Textbooks and workbooks play an important role in developing an understanding of mathematical concepts for both teachers and learners (Harries & Spooner, 2000). While teachers generally rely heavily on textbooks, they were a key resource while schools were closed due to COVID-19 lockdown regulations. The theory of Constructivism forms part of the theoretical framework for this study. Constructivism advocates that learners actively construct knowledge through experiences rather than passively receiving knowledge from the outside (Von Glaserfeld, 2001). Vygotsky believed that social interactions create experiences that facilitate the learning and meaning-making process (Vygotsky, 1978). This case study is underpinned by an interpretivist paradigm as it sought to examine the nature of VRs in three Grades 1 - 3 textbooks/workbooks. My research approach is primarily qualitative with descriptive statistics to assist in developing a more comprehensive understanding of the research questions. The study was guided by the analytic tool designed by Fotakopoulou and Spiliotopoulou (2008) which I adapted for Foundation Phase mathematics use. The framework provides insight on the type of VR, VRs relation to content, VRs relation to reality, the function of the VR and dimensionality of a VR. While the workbooks had many more VRs than textbooks, the dominant type of VR in textbooks and workbooks are images. The VRs mostly have a strong relation to content with a realistic relation to reality as they were predominantly 2D representation of a 3D object that had an exemplifying function (type b). , Thesis (MEd) -- Faculty of Education, Education, 2023

- Description: Property development is a sector which provides economic benefits to many countries worldwide. Such economic benefits are employment provision and GDP contribution to the economy. Interestingly, financial feasibility is one of the tools that can be used to ensure property development projects’ success. It has been therefore recognised that some of the property development entrepreneurs lack financial feasibility know-how which could position their property development businesses into a competitive edge and sustainability in this continuous fluctuating property market. Hence, the aim of this study was to examine the key factors and variable that drive financial feasibility in property development and generate a financial feasibility model which can be used by property development entrepreneurs to analyse the financial feasibility of property development projects. Based on the aim of this study, an extended review of the literature relating to property business, property development, demand planning and risk management within the built environment discipline was conducted in identifying factors affecting the perceived success of financial feasibility for property development projects internationally. The research reviewed literature in the property development industry by identifying the variables for profitability, outside advice, trend analysis and real estate strategies. The research methodology approach that was used for this study, a qualitative explanatory multi-case study where embedded unit of analysis and valuable insight was provided for the success of financial feasibility in property development internationally. Semistructured interviews were conducted with various industry experts as indicated below: • Project Manager at Property Company; • Project Manager at developer; • Development Manager; • Owner of Property Group; • Part time lecturer at NMU Built Environment; • Development consulting company CEO; vi • Trustgro Developments (Pty) Ltd: Managing Director; • Tswaranang Consulting – Managing Director; • Capelo Development Company (Property Development) Director; and • NMBM - Senior Director: Land Planning and Management. The interview questions and primary and secondary propositions were defined together with the validity and reliability of the research. The purpose of the qualitative research was to unravel key factors that determine the perceived success of international financial feasibility of property development projects. Replication logic was used to generalise the results and the findings of this research effort suggested that the following variables emerging from qualitative themes, positively influences the perceived success of the financial feasibility in property development projects: profitability, risk management, outside advice, trend analysis, property cycles and demand planning. The implication arising from this study is that the perceived success of international financial feasibility in property development projects has the following positive influencing factors: profitability, risk management, outside (specialist) advice, trends analysis, property cycles and demand planning which must be considered by property developers and investors to ensure the success of their property development interventions. The curriculum of property development and real estate management practice should equally take into account the afore-mentioned factors. , Thesis (MA) -- Faculty of Engineering, the Built Environment, and Technology, 2022

- Description: The purpose of this study was to evaluate the successes and failures of multiculturalism in South Africa and Canada through the lens of critical multiculturalism as its theoretical frame. As Canada is widely-acknowledged as having one of the best multiculturalism policy and implementation programmes in the world, this study aimed to draw lessons from the Canadian model of multiculturalism in order to make recommendations to improve multicultural practices in South Africa. It is worth noting that multiculturalism in Canada is not perfect as government still struggles to implement inclusive and reconciliatory programmes for the previously colonised Indigenous communities. This study used a qualitative thematic analysis to enable a comparison of multiculturalism in these two countries. The findings of this study suggest that having a comprehensive multiculturalism policy is fundamental to ensure that aspirations of a socially cohesive multiculturalism are not merely philosophical, but are formulated into government policies, with guidelines for implementation through the guidance of critical multiculturalism theory. The findings of this study also suggest that the persistent racialised socio-economic inequalities in South Africa continue to undermine multiculturalism and nation-building efforts. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2022

- Description: Preeclampsia is the new onset of hypertension and is one of the leading causes of maternal mortality in South Africa and the world. Preeclampsia is usually diagnosed after 20 weeks’ gestation. Due to South Africa’s poor level of antenatal care, the prediction of pregnant women at risk of developing preeclampsia can be an essential component of improving the level of antenatal. This study used an antenatal care dataset from a South African obstetrician. A review of the literature and existing systems was conducted to identify the eight risk factors. These risk factors are systolic blood pressure, diastolic blood pressure, maternal age, body mass index, diabetes status, hypertension history, nulliparity, and maternal disease. This study used antenatal care datasets from a South African obstetrician. Two models were developed that could accurately predict the development of preeclampsia, one before 16 weeks’ gestation and the other within three check-ups. The model was evaluated using five evaluation metrics: classification accuracy, area under the curve, precision, recall and F-Score. The results of this study show a promising future for the use of machine learning models in health care. To the researcher’s knowledge, this model is the first machine learning model for predicting preeclampsia using a South African dataset. Future work will revolve around validating the model on data collected from field studies in hospitals and clinics around South Africa , Thesis (MSc) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2022

- Description: In democracies and purportedly free market economies, questions of “who gets what, when, and how” ought to be resolved mainly through free competition, where those with the competitive advantage on merit are guaranteed to succeed. If it is political parties, they only have to compete well and fairly to win elections. If it is businesses, they ought to have the best value and price and they win customers. However, there are institutions which regulate this competition and political economic behaviour. Interest groups such as business chambers, industry and professional associations, as well as various structures of representation engage in the political economic space to sway the distribution outcomes from these “institutions” in the favour of their members. To do so, at times they use methods that affirm the principles and spirit of free competition and at other times, they do not. This thesis reviews the political economy of transformation within the construction sector in Nelson Mandela Bay to further advance knowledge within the subfield of political economy in South Africa. By looking at a specific economic sector, the study adds an important element to the sub-discipline, a nuance to the debates about the role of the state in the economy or macroeconomic policy and the much studied mining-energy complex. The study focuses on the role of small business forums created mostly by newcomers within the construction sector in the city and the methods they used to increase the share of their members in construction sector revenues. Their methods were unconventional and earned them the unfavourable term of ‘the construction mafia’. Through a grounded theoretical research process, this study details the story of the rise and fall of forums and dissects it in line with ongoing debates within political economy and related disciplines, particularly about the nexus between politics and business as well as the role of interest groups in pluralist political systems.

As such, they sought to make and remake institutions of the sector in ways that could increase their share of revenues.

- Description: In democracies and purportedly free market economies, questions of “who gets what, when, and how” ought to be resolved mainly through free competition, where those with the competitive advantage on merit are guaranteed to succeed. If it is political parties, they only have to compete well and fairly to win elections. If it is businesses, they ought to have the best value and price and they win customers. However, there are institutions which regulate this competition and political economic behaviour. Interest groups such as business chambers, industry and professional associations, as well as various structures of representation engage in the political economic space to sway the distribution outcomes from these “institutions” in the favour of their members. To do so, at times they use methods that affirm the principles and spirit of free competition and at other times, they do not. This thesis reviews the political economy of transformation within the construction sector in Nelson Mandela Bay to further advance knowledge within the subfield of political economy in South Africa. By looking at a specific economic sector, the study adds an important element to the sub-discipline, a nuance to the debates about the role of the state in the economy or macroeconomic policy and the much studied mining-energy complex. The study focuses on the role of small business forums created mostly by newcomers within the construction sector in the city and the methods they used to increase the share of their members in construction sector revenues. Their methods were unconventional and earned them the unfavourable term of ‘the construction mafia’. Through a grounded theoretical research process, this study details the story of the rise and fall of forums and dissects it in line with ongoing debates within political economy and related disciplines, particularly about the nexus between politics and business as well as the role of interest groups in pluralist political systems. Among other things, the study finds that the forums did not see the construction industry as a free market and did not take principles of competition in the sector as a given. As such, they sought to make and remake institutions of the sector in ways that could increase their share of revenues. In similar fashion to the roles of iinjoli nosokhaya in traditional isiXhosa ceremonies, they accorded to themselves the right to distribute benefits to their members contrary to legal and general market prescripts. , Thesis (PhD) -- Faculty of Humanities, School of Government and Social sciences, 2022

- Description: Globally social media has shown unprecedented levels of adoption and Social Media Analytics (SMA) is a rapidly growing topic. For governments, SMA holds the promise of providing tools and frameworks to collect, monitor, analyse and visualise social media data, usually driven by specific requirements from a target application. However, social media data is noisy and unstructured, and organisations struggle to extract knowledge from this data, and convert it into actual intelligence. This study argues that SMA can support intelligent decision-making for Citizen Relationship Management (CzRM). CzRM is a growing effort of governments around the world to strive to respond rapidly to their citizens by fostering a closer relationship thereby creating more effective and efficient service delivery. However, there is a little evidence in literature on empirical studies of any existing decision-making framework for CzRM and SMA adoption. In particular, there is a gap with regards incorporating SMA into decision-making for CzRM of governments, particularly in developing countries like South Africa. The aim of this study was to develop a framework that provides guidelines, including methods and tools, incorporating SMA into decision-making for CzRM in the Gauteng Provincial Government (GPG) and the Free State Provincial Government (FSPG) of South Africa. A Systematic Literature Review (SLR) and conceptual analysis method was conducted to design the Social Media Analytics Framework for Decision-making in the context of CzRM (the SMAF). The findings from the literature review revealed several benefits and challenges with SMA, in particular the shortage of skills, guidelines, methods and tools for SMA. These challenges were used to draft guidelines that were included in the framework, which consists of five components that can be used to derive intelligent information from SMA. The pragmatic philosophy and a case study design was used to generate an in-depth, multifaceted understanding of the underlying problems in the case of the GPG and the FSPG. The German North-West Metropolitan region was used as a third case study to provide a more global perspective and a case of a developed country in terms of Gross Domestic Product. The scope of the study was limited to social media posts by provincial citizens related to CzRM and service delivery. Both formative and summative evaluations of the proposed theoretical framework were conducted. The formative evaluation was conducted v | Page as an Expert Review to receive feedback of the framework from the experts in the field of Computer Science and Information Systems. The findings validated the framework and some minor improvements were made based on the experts’ recommendations. Focus Group Discussions (FGDs) with participants from government managers and decision makers in the three cases were conducted. Case documents for the three cases were collected and reviewed. All collected data was analysed using the Qualitative Content Analysis (QCA) method and common categories and themes were identified. Summative evaluations were conducted in the form of a Field Study, which consisted of an analysis of Twitter data from the three cases, and a closing FGD with Business Intelligence (BI) experts at the primary case of the e-Government department of the GPG. The findings revealed that SMA has been adopted in all three cases; however, while their strategies are comprehensive their implementations are very much in their early stages. The findings also highlighted the status of SMA in government and some potential gaps and areas for implementing the framework. , Thesis (PhD) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2022

- Description: The food supply chain plays an important role in the Zimbabwean food industry. More so sustainable food supply chain management (SFSCM) is a subject that has not received much attention, and yet it is so pertinent in determining food security in Zimbabwe. Zimbabwe has faced episodes of inadequate grain/cereal food reserves, hence the urgent need to develop a stakeholder framework for sustainable food supply chain management. The main objective of the study was to develop a stakeholder framework for SFSCM in the food industry. To accomplish the main objective, the research intended to achieve the following sub-objectives, namely to: establish the drivers for SFSCM; identify SFSCM practices within the food industry; identify the key stakeholders’ dynamic capabilities (SDCs) in the food industry and identify challenges faced by stakeholders in implementing SFSCM. The study also sought to establish the influence of: SFSCM drivers on implementing SFSCM practices; SFSCM drivers on SDCs; SFSCM practices on SDCs; SFSCM practices on SFSCM performance; SFSCM drivers on SFSCM performance; and SDCs on SFSCM performance. This study further sought to assess the mediation effect of: SFSCM drivers on the relationship between SFSCM practices and SDCs; SDCs on the relationship between SFSCM practices and SFSCM performance; SFSCM drivers on the relationship between SDCs and SFSCM performance and finally to assess the mediation effect of SDCs on the relationship between SFSCM drivers and SFSCM performance. This study employed a pragmatic philosophy that allowed for the collection of primary data using a fixed concurrent mixed methods (qualitative and quantitative) approach. The data analysis for this research included qualitative data from 22 participants and quantitative data from 292 respondents, all of whom were recruited through nine gatekeepers (Grain Marketing Board, Consumer Council of Zimbabwe, Food and Nutrition Association of Zimbabwe, Grain Millers Association of Zimbabwe, Ministry of Lands, Agriculture, Water and Rural Resettlement, Chartered Institute of Purchasing and Supply, Food and Agriculture Organization in Zimbabwe, Confederation of Zimbabwe Retailers and Zimbabwe National Chamber of Commerce). A thematic analysis was used to analyse qualitative data. For the quantitative data, the Statistical Package for the Social Sciences (SPSS) version 27 package was used to perform descriptive analysis, and principal component analysis for factor reduction and dimensional groups. Analysis of a Moment Structures (AMOS 26) program was used viii to perform structural equation modelling (SEM) for model fit evaluations and hypothesis tests. The mixed methods approach (both qualitative and quantitative) results identified regulatory pressure, market pressure, societal pressure, availability of resources, organisational culture and corporate objectives as some of the key SFSCM drivers. Additionally, the results identified the following as the key SFSCM practices: waste management, carbon emission reduction, logistics optimisation, water conservation, energy conservation, cost reduction and price efficiency, employment of competent people, cultivation of profitable grain crops, corporate social responsibility, fair distribution of food, human development on nutritious food consumption, food donations and continuously conducting consumer tastes surveys. Further, the mixed methods approach results cited the following key SDCs: sensing, seizing, reconfiguration, reflexive control, partner development, co-evolving and supply chain integration capabilities. Major challenges faced by stakeholders when implementing SFSCM were also identified and these involved lack of resources, lack of top management commitment, poor information sharing, lack of mutual trust amongst stakeholders, unmotivated employees, lack of government support, ever-changing food regulations, poor customer demand for sustainable and healthy foods, corruption and economic hardship challenges. The study also sought to establish relationships amongst variables. The mixed methods approach results revealed that SFSCM drivers have a positive influence on SFSCM practices, SDCs and SFSCM performance. The results also report a positive and significant influence of SFSCM practices on SDCs. The results further indicate that SDCs have a positive and significant influence on SFSCM performance. Although the qualitative findings reported a positive influence of SFSCM practices on SFSCM performance, the quantitative results from the SEM path analysis reported a very weak positive and insignificant influence of SFSCM practices on SFSCM performance. Mediation analysis was also performed using the quantitative data analysis only, and the results revealed that SFSCM drivers have significant partial mediation effect on the relationship between SFSCM practices and SDCs. The results also report that SDCs have a significant full mediation effect on the relationship between SFSCM practices and SFSCM performance. SFSCM drivers were found to have a significant ix partial mediation influence on the relationship between SDCs and SFSCM performance. Lastly, SDCs have a significant partial mediation effect on the relationship between SFSCM drivers and SFSCM performance. Based on the empirical results, conclusions were drawn, and recommendations were made. The research proposes a new stakeholder framework for SFSCM in the food industry. The study recommends that stakeholders consider providing training and education to all employees about the critical role of SFSCM in ensuring Zimbabwe's food security. Additionally, policymakers are urged to implement supply chain anticorruption and fair-trading policies in order to boost SFSCM performance. Stakeholder institutions are also urged to reward internal stakeholders who perform exceptionally well in terms of SFSCM in order to positively motivate all staff, and ultimately improve SFSCM. , Thesis (PHD) -- Faculty of Business and Economic Sciences, Business School, 2022

- Description: One of the major developmental crises an adolescent must overcome before becoming an adult is identity formation. Many studies focused on how the family influences the identity formation of adolescents, but little emphasis has been made specifically on how the absence of a father impacts the adolescent’s development of identity. This study aims to conduct a systematic review to examine the impact of absent fatherhood on the identity formation of adolescents. Several studies, from the year 2010 to date, have explored the impact of father absence on the identity formation of adolescents. The majority of studies conducted have been mostly quantitative and failed to explore the experiences of adolescents raised in absent-father households during this crucial stage of development. This study sought to add to the body of knowledge and bridge that gap by exploring the possible (negative or positive) impact of absent fatherhood in the identity-formation period of adolescents. This was a systematic review study that included a qualitative research design, whereby published literature and studies were identified through searching electronic databases. To synthesize and analyse the data, thematic analysis was used. This study’s exploration discovered that absent fatherhood can be experienced both positively and negatively by adolescents. Positively, it was found that a sense of independency developed in the adolescent and strengthens family relations and unity, with extended family members or external role models becoming more involved in the upbringing of the adolescent. Significantly, on the negative side, adolescents developed anger and resentment towards their absent fathers, questioning their absence and the individual’s sense of who they are and where they belong. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2022

- Description: Since the dawn of South Africa’s constitutional democracy, the right to strike has been protected. It is perceived to be fundamental to orderly collective bargaining and the courts have stressed the need to ensure that it is not unjustifiably limited or undermined. In the collective bargaining process, employers and employees have mechanisms at their disposal and a power-play ensues. One such mechanism, for striking employees, is to withhold their labour in an effort to compel employers to succumb to their demands. Newspaper articles and the jurisprudence that has emerged from the courts illustrate that strike-related violence has become a destructive feature of industrial action.[1] Not only are strikes destructive to the economy but they are often associated with violence. The courts have been inundated with claims seeking to interdict violent and protracted strikes. While many commentators are of the view that strike violence is a result of underlying socio-economic issues, which should be addressed by the government, employers and the general public often bear the brunt of the destruction and mayhem left in the wake of violent strikes. In the wake of one of the worst tragedies, the Marikana massacre, which saw 32 striking miners shot and killed when police opened fire at Lonmin's operations in the Northwest province, the South African government, organised labour, and employers were compelled to take swift action to address the deficiencies that existed when it came to the constitutionally entrenched right to strike. The Labour Relations Amendment Act 8 of 2018 seeks to address this. Whilst some of the provisions introduced by the amendments have been the subject matter of litigation resulting in progressive judgments, other provisions are yet to be judicially tested. , Thesis (LLM) -- Faculty of Law, Department of Mercantile law, 2022

- Description: The perceptions of causes of depression are diverse, formulated from many different factors such as personal experiences, education, generational and cultural influences, and religious beliefs. While there is a large body of literature on both depression and religion and culture, there is a limited amount available that synthesizes the findings of multiple different studies, finding key common themes. Therefore, this review aimed to develop a comprehensive understanding of how religious and cultural narratives describe and influence depression. As a result, a meta-ethnography was carried out to synthesise existing literature on cultural-religious narratives of depression within a South African context. Five published journal articles were sampled for translation and synthesis. From this process, three key themes were developed, namely Conflictual Coexistence, Observation-Based Discernment, and Status or Stigma. The result is a lens that is formed through a mixture of traditional cultural religious traditions and beliefs interconnected with contemporary ways of understanding and being. This framework for diagnosing and treating a mental illness is heavily reliant on observable symptoms. As a result, status or stigma can be attached to multiple aspects of the situation surrounding an individual with or suspected of having a mental illness. Stigmatisation can be noted to form a cycle that becomes inclusive of prognosis, finance/employment and not being able to fulfil culturally held expectations. As a result, future research, and therapeutic intervention of this mental disorder within this demographic will be better informed. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2022
