- Description: While climate change and rapid urbanisation are impacting our cities and existing infrastructure, population growth and resource scarcity are placing unprecedented pressure on our food systems. In light of such challenges and the Sustainable Development Goals, resilient solutions are being sought to move both urban development and food production towards a more sustainable future. In this context, Urban Agriculture (UA) has been identified as a possible mechanism to complement rural food production with many associated social, economic and environmental benefits for urban communities. Some of these benefits include increased food system resilience, better urban environmental management, circular and productive reuse of urban wastes, employment opportunities, reduced food miles and the promotion of social inclusivity. Through a sustainable food system lens and underpinned by Resilience Theory, this research study sets out to investigate and explore the considerations for UA development. The research study reviews UA literature to identify and analyse the common challenges which act as barriers to implementation, as well as the current or potential opportunities which could be leveraged to drive UA development. The insights gained from literature on UA and UA development frameworks; and the data gathered from qualitative interviews with experts working in UA-related fields in South Africa (SA), were used to build a conceptual framework for UA development in SA. The conceptual framework developed is intended to be used as a guide for local municipalities, urban planners, urban farmers, urban communities and UA support organisations in their approach to developing UA initiatives. The findings from this research study reveal that UA development in SA involves numerous actors at both provincial and municipal levels; and within private institutions, businesses, universities, farmer organisations and society. The findings also reveal that UA currently occurs at many levels in SA, with each level drawing a particular range of participants due to the various social, economic and/or environmental features of the initiative. Along with challenges associated with land access, the lack of UA-related knowledge, the threat of theft, vandalism and soil contamination (to name a few); a lack of understanding of how agriculture can fit into urban spaces was found to be a major obstacle. The findings suggest that this lack of understanding has led to an under-realisation of the full potential of UA in South African towns and cities; and an inability to incentivise and optimise the development of UA. Considering the findings derived from the investigation, the study proposes five major considerations for UA development in SA, all of which are unpacked in the conceptual framework. The study concludes by making recommendations for UA decision-makers and UA organisations to consider for future developments.

- Description: The Department of Basic Education (DBE) examiners’ diagnostic reports for 2012-2019 indicate that National Senior Certificate (NSC) learners mostly perform poorly in examination questions based on scientific investigations. The low performance by learners in these questions has been attributed to the failure by teachers to effectively mediate the learning of scientific concepts due to lack of science laboratories or poorly resourced laboratories in most rural schools. As a result, most learners are finding that scientific concepts are decontextualized and hence abstract. Thus, this study explored making use of Virtual Lab to mediate learning of scientific investigations using the topic Energy transformations. The study was located within an interpretive paradigm and a qualitative case study approach was employed. The study was conducted in four different rural schools in the Joe Gqabi district and seven Grade 11 Life Sciences teachers participated. Data was generated using semi-structured questionnaires, semi-structured interviews, lesson observation, workshop discussions, and journal reflections. The study was informed by Vygotsky’s (1978) Socio-Cultural Theory (SCT) as the theoretical framework, and Thompson and Mishra’s (2006) Technological Pedagogical Content Knowledge (TPACK) as the analytical framework. The results of this study showed that most educators have a positive predisposition towards the integration of Information and Communication Technologies (ICT) in their practice. The study found that using the Virtual Lab to teach Life Sciences has several benefits such as safe environment for conducting experiments; convenience and accessibility; positive teacher and learner attitudes and improvement on learner performance; elimination of physical limitations of a real lab; and availability top-class lab equipment and up-to-date reagents. The study also revealed some shortcomings that were associated with the use of the Virtual Lab. These are; lack of lab partner and peer-learning; and lack of direct supervision by a more knowledgeable facilitator. This study concluded that using the Virtual Lab enhances the quality of teaching scientific experiments in the selected under-resourced rural secondary schools. The study recommends the adoption of the Virtual Lab as a viable alternative to the conventional lab.

- Description: Higher concentrations of CO2 in the atmosphere is a major influence on climate change globally. Climate change is caused by greenhouse gases trapping too much heat from the sun in the atmosphere and thus, altering the climate through a rise in global surface temperatures and changing precipitation patterns. CO2 is the most prominent greenhouse gas found in the atmosphere and it is reported that by the turn of the century the CO2 concentration levels will have doubled if the current rate of emissions continues. However, the increase in atmospheric levels of the gas has been found to increase the capacity of maize plants and their water use efficiency to achieve higher yields through CO2 fertilisation. Simulation experiments conducted by the Rhodes University Botany Department found that the effect of elevated levels of CO2 of double the current concentration offsets the negative effects of drought on maize. A case study was conducted on commercial maize farmers in two regions of the Free State province in South Africa to estimate the economic impact of climate change on maize production. Although production is increasing in the province, adaptation to the changing climate is key to the sustainability of production. There is a trade-off between the negative effects of higher CO2 levels changing the climate and the positive effect of CO2 fertilisation. As predicted, the economic impact of climate change is the disruption of farming practices and the increase in costs of production as a result of adapting to climate change. Using a gross margin analysis, the study found that the larger maize farmers who benefit from economies of scale are able to adapt and grow their production whilst the smaller farmers are being pushed out of the market.

- Description: My thesis is a collection of poems that focuses on black mothering and motherhood, within the context of the Eastern Cape’s violent history, its oppressive patriarchal cultural traditions and religious structures. Drawing from my own experiences, my poems explore what Toni Morrison calls the historical ‘wounds’ of black women which are transferred to their daughters within everyday spaces like the kitchen and the lounge, through objects like tea cups, chair backs and the various foods that every black girl needs to be able to prepare in order to be ‘marriagable’, and how these continue to hurt and emotionally disfigure us. I also draw influence from Saidiya Hartman, Christina Sharpe and Tina Campt on black lives and the effects of slavery within their daily existences. And I am inspired by the intimacy and care with which Tadeusz Rosewicz writes about his relationship with his mother in Mother Departs and Sandra Cisneros’ use of interconnected vignettes to engage childhood, culture and community within marginalized space. Stylistically I am influenced by the structural innovations in Fred Moten’s The Little Edges and the dreamy landscape in the poetry of Federico Garcia Lorca. My collection includes prose and lyrical poetry, combining more formal sound and rhythmic structures with free verse, to bring to life motherhood and the narratives we carry from childhood into our adult lives.

- Description: Second- and third-generation calibration methods filter out subtle effects in interferometer data, and therefore yield significantly higher dynamic ranges. The basis of these calibration techniques relies on building a model of the sky and corrupting it with models of the effects acting on the sources. The sensitivities of modern instruments call for more elaborate models to capture the level of detail that is required to achieve accurate calibration. This thesis implements two types of models to be used in for second- and third-generation calibration. The first model implemented is shapelets, which can be used to model radio source morphologies directly in uv space. The second model implemented is Zernike polynomials, which can be used to represent the primary beam of the antenna. We implement these models in the CODEX-AFRICANUS package and provide a set of unit tests for each model. Additionally, we compare our implementations against other methods of representing these objects and instrumental effects, namely NIFTY-GRIDDER against shapelets and a FITS-interpolation method against the Zernike polynomials. We find that to achieve sufficient accuracy, our implementation of the shapelet model has a higher runtime to that of the NIFTY-GRIDDER. However, the NIFTY-GRIDDER cannot simulate a component-based sky model while the shapelet model can. Additionally, the shapelet model is fully parametric, which allows for integration into a parameterised solver. We find that, while having a smaller memory footprint, our Zernike model has a greater computational complexity than that of the FITS-interpolated method. However, we find that the Zernike implementation has floating-point accuracy in its modelling, while the FITS-interpolated model loses some accuracy through the discretisation of the beam.

- Description: A vast body of literature reveals the paradigm shift of South Africa’s economy from an agricultural community to an industrial economy. Elbra (2013) illustrated that South African mining host communities viewed that mineral endowments have become a “resource curse” instead of a driver of local economic development for the benefit of the community. To understand the mining and community conflict and their subsequent complexities, the Marikana massacre in August 2012 must be revisited (Bell, 2016). The problems may be broadly summarised as a lack of stakeholder engagement and inclusivity. Studies involving stakeholder management and co-management focused on the identification of stakeholders and their management. The research evaluated the co-management practices between mine management and a local community. It considered the challenges that emanated from the co-management practices. The primary focus of this research has been to evaluate the co-management features between the mine management and the local community and to identify the challenges associated with co-management from a mine management perspective. Furthermore, the research attempted to find effective co-management practices between the mine management and the local community which may be used to improve the partnership. Armitage, Berkes and Doubleplay (2007) recognised that in facilitating effective co-management, the commitment towards fulfilling good governance and accountability was paramount in ensuring that the rights and obligations of both private and public actors were achieved. However, Ran and Qi (2018) acknowledged that such partnerships were not immune to challenges because the poor implementation of co-management features like power-sharing could collapse a co-management partnership. This study aimed to evaluate the current co-management practices from the mine management’s perspective. A literature search revealed the range of co-management features that explained the different use of practices. The features included co-management and power sharing, co-management and institution building, co-management and trust and social capital, co-management as a process, co-management and problem solving, and co-management and governance. The study evaluated the co-management features between the mine management and the local community, identified the current challenges associated with co-management from a mine management perspective and attempted to make recommendations on effective co-management practices between the mine management and a local community. A qualitative case study method was employed. This method allowed the researcher to evaluate multifaceted matters which may have been investigated in the past but not inconsiderable detail (Baxter and Jack, 2008). Data was sampled using purposive sampling. This was because the population sample was chosen according to their roles and responsibilities and their involvement in the co-management between the mine management and the local community. Data was collected through semi-structured interviews and document analyses. The findings of the research were derived from a range of company documents. Thematic analysis was employed to understand the practices of co-management which underpinned the co-management partnership between the mine management and the local community. It was found that there was a positive relationship between the literature study and the response from the mine management. The shared responsibilities emerged out of a dialogue characterised by deliberation and negotiations between the mine management and the stakeholders. Berkes (2009), asserted that co-management bore a resemblance to the process of the sharing of ideas of how responsibilities could be better shared and that it emanated from a process of deliberation and negotiation. Furthermore, if the evolution of the co-management partnership was not managed carefully, it could pose a risk to the partnership itself. It was acknowledged by the research respondents that there were complications involved in having the community as a shareholder in the mine, but equally, the community showed an appreciation of being involved in building a sustainable mine. The model of sustainable partnership emphasised that any viable partnership should adopt this model to achieve a sustainable performance (Thomson and Boutilier, 2011). This research showed that the co-management practices between the mine management and the local community concurred with the findings of Zvarivadza (2018). Trust and transparency between mine management and the community could go a long way in ensuring that the mine fulfilled its legal responsibilities in the local community where the mine is located.

- Description: SMEs in South Africa and other developing countries have been slow to take up sustainability reporting. This qualitative study is aimed to study the challenges and barriers faced by SMEs, together with the potential benefits for SMEs participating in this type of reporting. It also makes recommendations about how SMEs can participate in and benefit from sustainability reporting. The study shows that indeed there are several challenges in terms of getting involved in sustainability reporting for SMEs. On the other hand, the research finds that the SMEs who are already participating in sustainability reporting can show the benefits of engaging in sustainability reporting and that these benefits far outweigh the challenges. The participating SMEs are also able to show that they have attained a competitive advantage as a result of engaging in sustainability reporting. If, however, sustainability reporting is to become entrenched into SMEs, a few changes need to take place to address challenges such as lack of information about sustainability reporting and its benefits, lack of regulations and more importantly, lack of awareness about sustainable development. As the South African government begins to respond to issues such as climate change, skills development and good governance, it will become necessary for them to introduce regulations to manage this risk. It is also highly possible that in the next few years, reporting will become a regulatory requirement that SMEs will be forced to comply with to continue to do business. The SMEs who are already practising sustainability practices will benefit from being first movers. Those SMEs who start sooner rather than later will already have the internal resources and capabilities to take advantage of the legislative environment. They will have a head start over their rivals in terms of gaining competitive advantage.

The study shows that indeed there are several challenges in terms of getting involved in sustainability reporting for SMEs. On the other hand, the research finds that the SMEs who are already participating in sustainability reporting can show the benefits of engaging in sustainability reporting and that these benefits far outweigh the challenges. The participating SMEs are also able to show that they have attained a competitive advantage as a result of engaging in sustainability reporting. If, however, sustainability reporting is to become entrenched into SMEs, a few changes need to take place to address challenges such as lack of information about sustainability reporting and its benefits, lack of regulations and more importantly, lack of awareness about sustainable development. As the South African government begins to respond to issues such as climate change, skills development and good governance, it will become necessary for them to introduce regulations to manage this risk. It is also highly possible that in the next few years, reporting will become a regulatory requirement that SMEs will be forced to comply with to continue to do business. The SMEs who are already practising sustainability practices will benefit from being first movers. Those SMEs who start sooner rather than later will already have the internal resources and capabilities to take advantage of the legislative environment. They will have a head start over their rivals in terms of gaining competitive advantage.

- Description: The phenomenon currently understood as ‘borderline personality disorder’ (BPD) has been complex and multifaceted since its inception. Previous studies have focused on the validity of The Diagnostic and Statistical Manual of Mental Disorders (DSM) conceptualisation of BPD, aetiologies of BPD, the psychologies of persons diagnosed with BPD, and the gendered nature of BPD. This study aimed to specifically explore South African practising psychologists’ perceptions of BPD. Through thematic analysis from a constructivist, post-modern paradigm, this study aimed to explore the perceptions and experiences of practising psychologists on BPD, as well as the usefulness of the DSM in working with BPD in a non-western society such as South Africa (SA). The study sampled two Counselling and two Clinical psychologists practising in the South African context, with exposure to and experience in working with BPD. Collectively, results in this study identified psychologists’ perceptions of shortcomings in the usefulness of the DSM’s approach to categorising phenomena associated with BPD, and brought attention to a need for further research and attention into the role of psychologists’ in the construction of BPD. This study seeks to represent psychologists’ practical experiences and perceptions, in an attempt to add contextually relevant findings on the DSM’s construction of BPD, and to contribute to challenging the stigma and misunderstanding associated with BPD. Specific practice implications and recommendations for future research are discussed within.

- Description: Social media has revolutionized the way people send and receive information by creating a new level of interconnected communication. However, the use of the Internet and social media brings about various ways in which a user’s personal data can be put at risk. This study aims to investigate what drives the disclosure of personal information online and whether an increase in awareness of the value of personal information motivates users to safeguard their information. Fourteen university students participated in a mixed-methods experiment, where they completed a questionnaire before and after being shown the data stored about them by online platforms to determine if changes occur in their intention to disclose. Following completing the initial questionnaire, the participant viewed the personal data stored about them by Facebook, Google, and Instagram. Other online tools such as Social Profile Checker, Facebook View As, and HaveIBeenPawned were used to see the information publicly available about each participant. Together these findings were discussed in a semi-structured interview to determine the influence of attitudes, subjective norms, and awareness on the cost-benefit analysis users conduct when disclosing information online. Overall, the findings indicate that users are able to disregard their concerns due to a resigned and apathetic attitude towards privacy. Furthermore, subjective norms enhanced by FOMO further allow users to overlook potential risks to their information in order to avoid social isolation and sanction. Alternatively, an increased awareness of the personal value of information and having experienced a previous privacy violation encourage the protection of information and limited disclosure. Thus, this study provides insight into privacy and information disclosure on social media in South Africa. It reveals more insight into the cost-benefit analysis users conduct by combining the Theory of Planned Behaviour with the Privacy Calculus Model, as well as the antecedent factors of Trust in the Social Media Provider, FOMO, and Personal Valuation of Information.

- Description: The goal of this study was to determine whether asymmetric price transmission (APT) exists between the prices of South African UG-2 Chrome ore, Charge Chrome, Nickel and Chinese Domestic 304 Stainless steel Cold Rolled Coil prices. Monthly time series data for the period January 2009 to July 2019 was analysed. The Non-Linear Autoregressive Distributive Lag (NARDL) model was applied to test for the presence of price asymmetry between the four variables. Firstly, it was observed that the four variables are cointegrated in the long-run. Secondly, no evidence of price asymmetry was found to be present within the Stainless steel supply chain. The reason for this is most likely due to the extremely close-knit and highly concentrated nature of this industry at each level within the supply chain. The industry can be very opaque to external observers even though the distribution of pricing information is very efficient for participants within the industry.

- Description: Music holds a privileged position in enhancing therapeutic well-being, supporting life skills development in youth and adolescents, and shaping cultural identities. As such, music has been closely related to youth culture, especially as it pertains to youth rehabilitation and identity formation. Studies (e.g., Duffy and Fuller, 2000; Miranda et al, 2013; Strayhorn, 2011; Tomasello, 2016) highlight the value of utilising music in youth rehabilitation, and acknowledge the intrinsic value of music to facilitate psychological and social change for individuals who would not otherwise benefit from psycho-education, or other didactic modes of youth rehabilitation. That said, Tyson (2005) developed the RAP music scale to psychometrically validate the underlying constructs of youth’ attitudes and perception of rap music in the United States of America, in order to use the instrument for music-based youth rehabilitation programs. The development of the RAP music scale informed the creation and validation of the Kwaito-music Attitude and Perception (KMP) Scale, the subject of my Masters thesis. Following suggestions from Morrison (2014), my study sought to psychometrically validate the properties of the Kwaito-music Attitude and Perception (KMP) Scale. The KMP was found to be a reliable measure of kwaito music attitudes and perception amongst a sample of South African youth who listen to this genre of music. The internal consistency of the questionnaire revealed a Cronbach’s α (Alpha) value of 0.820. Limitations of the project including reduced factor extraction and sample size constrains are discussed. It is envisioned that results from this study will find resonance with youth-community programs, and rehabilitation projects utilising music as a medium of healing amongst South African youth.

- Description: Information Technology (IT) is growing rapidly and has become an integral part of daily life. It provides a boundless list of services and opportunities, generating boundless sources of information, which could be abused or exploited. Due to this growth, there are thousands of new users added to the grid using computer systems in a static and mobile environment; this fact alone creates endless volumes of data to be exploited and hardware devices to be abused by the wrong people. The growth in the IT environment adds challenges that may affect users in their personal, professional, and business lives. There are constant threats on corporate and private computer networks and computer systems. In the corporate environment companies try to eliminate the threat by testing networks making use of penetration tests and by implementing cyber awareness programs to make employees more aware of the cyber threat. Penetration tests and vulnerability assessments are undervalued; are seen as a formality and are not used to increase system security. If used regularly the computer system will be more secure and attacks minimized. With the growth in technology, industries all over the globe become fully dependent on information systems in doing their day-to-day business. As technology evolves and new technology becomes available, the bigger the risk becomes to protect against the dangers which come with this new technology. For industry to protect itself against this growth in technology, personnel with a certain skill set is needed. This is where cyber security plays a very important role in the protection of information systems to ensure the confidentiality, integrity and availability of the information system itself and the data on the system. Due to this drive to secure information systems, the need for cyber security by professionals is on the rise as well. It is estimated that there is a shortage of one million cyber security professionals globally. What is the reason for this skills shortage? Will it be possible to close this skills shortage gap? This study is about identifying the skills gap and identifying possible ways to close this skills gap. In this study, research was conducted on the cyber security international standards, cyber security training at universities and international certification focusing specifically on penetration testing, the evaluation of the need of industry while recruiting new penetration testers, finishing with suggestions on how to fill possible gaps in the skills market with a conclusion.

- Description: Domestic service has long been a major sector of the South African labour market, for black women particularly, who must support their family and children. Existing research has stressed the way in which race, class and gender has shaped the oppressive character of domestic service in South Africa. In this narrative study a new slant is provided on this existing theoretical discussion of domestic labour, one that is focused on exploring the agentic human being beyond ‘the servant question’. This study uses narrative interviews with domestic workers in Makhanda/Grahamstown in the Eastern Cape province of South Africa to show how we can expand on potentially limited or constricted passive ‘domestic worker identities’ and ideas/beliefs about women who do domestic work. A performative and positioning narrative analysis is used to explore the subject positions of domestic workers in their stories about their childcare arrangements. This analysis examines multiple shifting identities and positions that are used by domestic workers in relation to their maternal subjectivity and their audience (here, a white trainee-psychologist esearcher), while highlighting the significance of narrative methodology in making these positions visible. The areas of focus were their history, experience of domestic work, life outside of domestic work, family network/dynamics and personal childcare arrangements. Under these areas of focus the following was analysed: the ways in which the storyteller positioned herself in her narrative, how she compared/contrasted or located herself in relation to the other, claims of identity that were made, what she incorporated or purposefully left out, words and phrases that were chosen, which sections of talk were embellished or elaborated on and appeals that were made to the interviewer (Riessman, 2002). Through exploring the micro-practices of domestic workers’ lives the study found that there were various subject positions constructed and used by this group of women. Findings showed that domestic workers positioned themselves actively as breadwinners, good mothers who give their children opportunities that they were not given, nurturers and crafty mothers who secure good care for their children. In contrast to these active subject positions, positions of sacrifice were performed when domestic workers spoke about leaving their young children in the care of another while they worked. The study also found that participants managed complex positions of disappointment and unmet expectations for a better life in the new South Africa by using narratives of resistance and agency. In certain instances, identity appeals were made to the interviewer that they, and other women who do domestic work, are entrepreneurial and creative with their income and possess skills outside of their day-to-day household cleaning jobs. This was interpreted as an attempt to extend the domestic worker identity positioning beyond the traditionally accepted notions of unskilled/uneducated women who do domestic work. In the study this allowed for more subject positions to be taken up in terms of identities and selves, beyond just being a “domestic worker”.

- Description: Over the years, scholars have noted the importance of organisations managing the performance of their employees by effectively maintaining their commitment. Hence, l ite rature highlighted that employee s have the potential to be recognised as a source of competitive advantage for an organisation and not a resource of an organisation. The main aim of the study was to explore the role of supervisors in developing employee commitment in a Namibian Public Ins titution from the subordinates’ perspective. The focus of this research was to understand how subordinates were included in decision making and were supported by their supervisors , and on how subordinates received feed b ack on role fulfilment and performance from their supervisors. Furthermore, the study described how subordinates viewed the leadership behaviour of their supervisors and how this i nfluenced employee commitment. The data was collected using qualitative me t hods through semi - structured face - to - face interview s with the subordinates of the selected institution. During this study, a sample of 15 subordinates taken from a population of 266 within the institution’s structure was inte rviewed . The interview quest ion s were based on how supervisors included subordinates in decision making, developed subordinates ’ support and delivered feedback on role and performance. The study used secondary data to determine the level of performance against set targets of the inst itu tion, using the annual performance report of the institution. In addition , the study used the staff access control syste m to determine the work time s of employees Lastly, the study analysed the data regarding staff resignation for the last five years to a ssess the level of staff turnover rate of the institution. The study f ound that the subordinates felt the re should be greater subordinate inclusion in decision making, increased levels of re gular feedback and higher levels of support shown by supervis ors t o subordinates when e xecuting their jobs. The study further highlighted the importance of supervisors to develop the ability of shifting from one leadership style to another depending on the situation at hand. The study reviewed six leadership style s that could influence commitment . Therefore, the study recommend s th at the institution direct its attention towards developing the situational leadership skills of their supervisors and developing their skills to enable them to better harmonise teamwork, increas e regular communication and give regular feedback to their subordinates . The results from this research will be beneficial to public institutions within the region and will, in add ition, enhance the academic body of literature in this field . The s tudy will draw the attention of supervisors to the importance of their behaviour, conduct, and their subsequent impact on employee commitment.

- Description: The geology of the SE limb of the Kromberg type-section, its origin and its evolution has remained controversial for more than five decades since its discovery by Viljoen and Viljoen (1969). Different lithostratigraphy and geodynamic models have been proposed that were centred around two end-member models, a continuous layer-cake stratigraphy model (Viljoen and Viljoen, 1969c, Lowe et al., 1999) or a tectono-stratigraphic model (de Wit et al., 2011, Furnes et al., 2012). Additionally, the Kromberg type-section mafic-ultramafic sequence represents a relatively thin, dismembered sequence compared to other formations or ‘complexes’ in the Onverwacht Group. Previous geology workers relied on the field interpretations for the construction of the geological architecture of the Kromberg type-section; but no petrographic analyses were conducted for accurate, integrated geological characterization of different rock compositions. To address controversies centred around the Kromberg type-section geology and geodynamic setting, this study is aimed at testing previously proposed stratigraphic and geodynamic models by integrating high-resolution geological mapping, petrography, mineral chemistry and whole-rock geochemistry to verify rock characterization. The aim is to accurately reconstruct the volcano-sedimentary architecture of the Kromberg type-section and to compare this to the results of previous fieldwork. Moreover, the manner in which the Kromberg sequence may relate to current Archean geodynamic models is evaluated, and a new model explaining the origin and evolution of the Kromberg type sequence is proposed. The integration of high-resolution field mapping, petrography and geochemistry has allowed for a high precision study and that has resulted in the construction of a new geological architecture for the SE limb of the Kromberg type-section. The stratigraphic thickness of the SE limb of the Kromberg sequence comprises dominant c. 80% volcanic rocks and minor c. 15% intrusive rocks, intercalated by 7 volcano-sedimentary chert horizons (c. 5%). Four main rock types (groups) are present in the Kromberg type-section with two sub-types of komatiitic basalts (the Badplaas-type and Geluk-types), Fe-rich tholeiitic basalt, cumulate peridotite, and a metadunite. Although the Kromberg type-section records sub-greenschist to lower greenschist facies, more than 50% of the rock samples classify as altered with parts of the stratigraphy recording extensive chloritization and severe ocean-floor silicification. Geochemical data revealed an enrichment in SiO2, K2O, Ba, Rb and variation in HREE for highly silicified samples whereas, chloritized samples are enriched in FeO and have concave upward LREE patterns. Partially chloritized tholeiites and komatiitic basalts have overlapping SiO2 signatures, relatively flat REE patterns and a small negative Nb anomaly in the primitive mantle-normalized spider diagrams. This thesis provides the first Lu-Hf isotope data on whole rock samples from the Kromberg type-section. The εHf values at t=3.33 Ga range between -0.62 to +4.18 and Hf model ages range between 3.43 - 4.27 Ga. The rock compositions are compared to the geochemistry of other greenstone belt rocks, which are considered to provide insight onto the geodynamic setting under which the Kromberg mafic-ultramafic sequence formed. The rock compositions reveal plume-related processes where a primitive mantle melt interacts with recycled mafic crust or mafic lower crust of older units of the Onverwacht Group. Only a small Nb anomaly is found in some samples and the data plots outside the subduction zone (forearc and back-arc) field. Rare-Earth element profiles are flat and not consistent with a subduction zone signature, as proposed in previous studies. Rifting of an oceanic floor in a juvenile basin is proposed for the formation of the Kromberg type-section rocks, prior to being tectonically accreted during regional transpressional deformation at c. 3.23 Ga.

- Description: This study sought to investigate the experiences of leaders involved in a transition from specialist role to leadership role at the Eastern Cape Development Agency, South Africa. A qualitative case study within a constructivist paradigm was adopted. Bridges’ (1991) theory of transition was used in this study to understand and analyse the process of transition in this study. The study used purposive sampling technique, where six leaders were selected and interviewed. The data was analysed through inductive and content analysis techniques. The findings are presented thematically and supported with participants verbatim. The study established that as specialists transition to leadership roles they experience lack of role clarity, stress (role strain), resistance, inadequate support, shock, increased work load (role strain) and role conflict. These experiences influence on their role identity, expertise, peer relationships and financial status. The study also established that for smooth and successful transition, consultation, participation, proper succession planning, and training is vitally important. This was necessary to ease the tension between management, leadership, specialist responsibilities, and resistance from specialists. The study recommends adequate support and preparation in all stages of transition to ensure that the organization benefits from the transition.

- Description: South Africa is on track to attaining the 2030 Agenda on reducing under-five deaths to 25 deaths per 1000 live births at its current momentum, however an unacceptable amount of infants are still at risk from preventable illnesses. Malnutrition is the major underlined cause of infant mortality rates in South Africa. Exclusive breastfeeding rates are low nationwide due to low exposure to breastfeeding information, some mothers having other commitments and others having breastfeeding difficulties. Implementation and expansion of simple, cost-effective interventions, such as exclusive breastfeeding for six months to reduce and/or prevent infant mortality rates, remains low in South Africa. The aim of the study was to determine one infant health issue of major concern to participants in two rural villages in the Eastern Cape, namely Glenmore and Ndwayana. The identified infant health issue was used to design an educational intervention in the villages. This was the second phase of this study. A community-based participatory approach was utilized in which the Angus Gillis Foundation, a non-profit organization that works in these communities, was one of the stakeholders. Stock status of WHO priority medicines for infants, semi-structured interviews and focus group discussions were carried out during the baseline study. The intervention phase contained pre-2 intervention semi-structured interviews with ten pregnant women followed by an educational intervention with nine out of the ten; and finally, a post-intervention with seven out of the ten women. A questionnaire was completed by members of the Angus Gillis Foundation to provide feedback on the sustainability of the intervention. Semi-structured interviews revealed that medicines stocked at the clinic parallel those indicated in the WHO priority medicines list for infants. The results from the focus group discussions indicated that mothers do not exclusively breastfeed their infants during the first six months. Pre- and post-intervention results on exclusive breastfeeding illustrated a positive change in participants’ knowledge and intent to breastfeed exclusively for six months. They showed a better understanding of the importance of exclusive breastfeeding and indicated a more focussed intention and confidence to carry out optimal breastfeeding practices. In the questionnaire the members of the Angus Gillis Foundation stated that the intervention is sustainable as it was linked with the existing networks. These include educational programs carried out in the villages by the foundation together with positive health champions, community health workers and women self-help groups; which will be able to build on the present knowledge base. Finally, the study also included the design of a booklet on the identified infant health issue. In conclusion, participants highlighted lack of understanding regarding breastfeeding as an issue of concern during the baseline phase of the study. This community-based educational intervention improved the understanding of breastfeeding among the participants, resulting in a positive change in perception with regards to exclusive breastfeeding practices.

- Description: The study aims to map the transition of a traditional university into an entrepreneurial university. The concept of the entrepreneurial university has been established as a game changer in the development and innovation spheres at higher education institutions worldwide. In the year 2002, the South African Higher Education sector embarked on a modelling and redefining journey which gave birth to the National Plan for Higher Education. The Entrepreneurship Development in Higher Education has undertaken work done on the entrepreneurial university which gave rise to the mapping that breeds ground towards policy. This study sought to investigate whether there is a conducive environment at Rhodes University, with an entrepreneurial climate to develop institutional capabilities and build new networks. The research highlights the current direction of Rhodes University and elaborates on the potential for the transition towards an entrepreneurial university. An overview of the entrepreneurial university was provided through an analysis of literature, which dominated in the more developed countries compared to South Africa. The researcher adopted a qualitative research study to capture the direct experiences of the individuals that are in the institution. A questionnaire was designed using the Organisation for Economic Co-operation and Development Guiding Framework and the direct perceptions of academics from the university were documented. The objectives were firstly, to explore elements of leadership and governance that enhance transformation of Higher Education Institution from a traditional university towards an entrepreneurial university. Secondly, to investigate internal resources that enhance Organisational Capacity with specific reference to people and incentives. Lastly, to determine how Teaching and Learning strengthen entrepreneurship development. The interviews revealed that the challenges faced by the institution were closely linked to those recognized by existing literature. What was interesting to note, limited funding and support were regarded as the most significant problems, closely followed by unskilled people and lack of infrastructure. It is suggested that cultivating and nurturing an entrepreneurial culture is of paramount importance together with the creation of a policy framework. Furthermore, the study concluded with practical recommendations proposed to management regarding the three strategic lenses. The research also illustrated that Rhodes University may not be viewed as being entrepreneurial but certainly has pockets of entrepreneurship and innovative activities.

- Description: Coming out of more than a century of concern over the commercialization and monopolization of media ownership, this study highlights some areas of opportunity for alternative media in the United States. Holding an ideal of participatory democracy, driven by an educated electorate, the research considers an example of US media action, Ye s ! magazine, from the perspective of alternative media and social movement theories. As alternative media are most generally a response to the mainstream model which acts in the interests of profit rather than public participation in politics, this thesis will cover not only democratic responsibility, but also mainstream media ownership and organization when considering the current manifestation of Ye s ! magazine. Inspired by a frustration with the concentration of mainstream media ownership, and consequently journalistic homogenization, this research explores opportunities for democratic media divergence and contestation. After 18 years of publication, Ye s ! was chosen as an ideal candidate for research due to its sustainability and longevity as one such critical media organization. Through in-depth interviews with Yes! personnel, and ideological analysis of Yes! articles, the following case study research explores the complexities that construct Ye s ! magazine, a corporately independent publication from Bainbridge Island, Washington.

- Description: Calibration in radio interferometry describes the process of estimating and correcting for instrumental errors from data. Direction-Dependent (DD) calibration entails correcting for corruptions which vary across the sky. For small field of view observations, DD corruptions can be ignored but for wide fild observations, it is crucial to account for them. Traditional maximum likelihood calibration is not necessarily efficient in low signal-to-noise ratio (SNR) scenarios and this can lead to ovefitting. This can bias continuum subtraction and hence, restrict the spectral line studies. Since DD effects are expected to vary smoothly across the sky, the gains can be parametrised as a smooth function of the sky coordinates. Hence, we implement a solver where the atmosphere is modelled using a time-variant 2-dimensional phase screen with an arbitrary known frequency dependence. We assume arbitrary linear basis functions for the gains over the phase screen. The implemented solver is ptimised using the diagonal approximation of the Hessian as shown in previous studies. We present a few simulations to illustrate the performance of the solver.
