- Description: The South African spearfishery forms a small component of South Africa’s complex coastal fishery. Although the smallest, this fishery sector has the largest proportion of data deficient species, and as a consequence is poorly managed. Oplegnathus conwayi (Cape knifejaw) is an example of one of these species for which there is very little and outdated biological and ecological data. This species is among the top target species by recreational spearfishers in South Africa. This thesis aimed to improve our socio-ecological knowledge of the South African spearfishery through the collection of biological and Fishers’ Ecological Knowledge (FEK) information on Oplegnathus conwayi, and human dimension information on the South African spearfishery. Monthly biological samples were collected through routine sampling (spearfishing) and augmented by recreational spearfishers. A total of 254 fish were collected from the warm-temperate coastal zone (East London – Cape Agulhas), 28 from the sub-tropical zone (Durban – East London) and 23 from the cool-temperate zone (Cape Agulhas – Cape Point). The results indicated that Oplegnathus conwayi is a slow-growing species, with a maximum recorded age of 27 years. The population sex ratio was skewed, with males dominant in the population (1M:0.6F). The length- and age-frequency distributions were, however, similar for both sexes. No significant differences were observed between male and female growth (LRT, p > 0.05), with the overall population growth curve being best described as L(t) = 697.15(1-e-0.06(t-6.30)). Males matured at a slightly larger size than females, however, no significant differences were observed (LRT, p > 0.05). The length- and age- at-50% maturity was 330 mm (FL) and 5.73 years for the full population, respectively. Histological analyses showed that Oplegnathus conwayi are asynchronous spawners with a gonochoristic reproductive style. Macroscopic staging and gonadosomatic index results indicated a protracted spawning season for Oplegnathus conwayi, with a peak in spring. A survey was designed and disseminated to collect FEK on the biology and population status of Oplegnathus conwayi and human dimension information on South Africa’s spearfishery. A total of 103 survey responses were received, of which 94 were regarded as specialised (spearfishers who had greater experience, skill and avidity, and maintained spearfishing as an important component of their lifestyle) spearfishers. Based on the responses of the specialist spearfishers, the top four main species caught by spearfishers from this survey were Seriola lalandi (13.9%), Pachymetopon grande (11.7%), Oplegnathus conwayi (11.4%) and Sparodon durbanensis (11%), and the majority of respondents indicated that there had been no changes in abundance, size and catches of these species in the years that they had been spearfishing. Respondents indicated that Oplegnathus conwayi are most commonly targeted in the Eastern Cape and are found at depths of up to 40 m. Respondents also indicated that there may be a seasonal onshore (Summer/Winter) and offshore (Summer/Winter) migration with year-round spawning and a peak in November, December and January. The incorporation of spearfishers into the data collection, both through the collection of specimens and their FEK, was beneficial to this study. Besides providing samples from a broader geographical range than the primary collection area, the collaboration with spearfishers has promoted the inclusion of this group into the management system. The findings of this study also suggest that FEK data can be more reliable if the concept of recreational specialisation is incorporated into data collection. While the FEK suggested that the population was stable, a stock assessment is necessary to fully understand the population status and implement management strategies. Nevertheless, the key life history characteristics (slow growth and late maturation) observed in this study are characteristic of species that is vulnerable to overexploitation, and thus the precautionary approach should be applied. The reproductive information collected in this study has provided information for the implementation of an appropriate size limit regulation for Oplegnathus conwayi. Here, a minimum size limit of 400 mm TL, which corresponds approximately with the length-at-50% maturity of 330 mm FL, would be appropriate to allow fish to mature and spawn, and reduce the likelihood of recruitment overfishing. Reduction in the bag limit from five to two fish per person per day may also be appropriate as a precautionary measure until a stock assessment has been completed. Finally, the incorporation of stakeholder into biological collection and the use of FEK may be a useful approach for other data deficient species and in countries with limited resources for ecological research. , Thesis (MSc) -- Faculty of Science, Ichthyology and Fisheries Science, 2021

- Description: Extensive evidence of atrocities committed against black workers on white-owned farms has consistently been uncovered by progressive organisations working in the rural areas in South Africa. The evidence suggests the need for a thorough and systematic investigation of the nature and extent of violence on the farms, as well as a more systematic exposure of the findings. For the most part, the personality of rural South Africa remains a mystery to urban dwellers. The Black Sash and its rural project, the Transvaal Rural Action Committee (TRAC), approached the Project for the Study of Violence to undertake this research and this report was first presented at the Project's seminar programme at the University of the Witwatersrand. Its findings have provoked strong responses from the farming sector. Kobus Kleyhans, the Deputy Director, General Services of the South African Agricultural Union (SAAU), was quoted in The Star as saying, ‘According to my observations, the situation (on the farms) is quite different. I reject these findings with contempt; they are nothing near the real situation... I will not deny, that some farmers do not treat their workers as they should, but this sort of information is not representative’. (The Star; October 1990) In reply, it should be emphasised that firstly, while this study was conducted only in the South Eastern Transvaal, the case studies in this report are not isolated incidents but were selected out of a large range of similar occurrences in the area. Secondly, rural advice offices in the Western and Northern Transvaal, have reported similar cases of violent abuse of labourers on white owned farms in their areas. Although the specific contours of the communities in these regions have not been investigated, some of the case studies directly corroborate the findings of this report. The timing of this report is opportune as it coincides with President De Klerk’s announcement that the Land Acts of 1913 and 1936 are to be abolished. These Acts have been pivotal in forging and determining the violent and exploitative relations on the land. The announcement is therefore welcomed as a significant step towards creating the conditions for changing the balance of power on the land. At the same time, this report serves as a warning against the belief that the scrapping of the Land Acts will put an end to the varying forms of violence on the farms. Just as repealing these laws will not necessarily ensure equitable redistribution of the land in South Africa, so too do they not necessarily signal a move towards more equitable labour relations on white farms. This report makes this clear in three ways. Firstly, the racist attitudes and convictions of many white farmers is shown to underpin much of the violence on the farms. These attitudes will prevail well after the scrapping of the Acts. A reversal of these attitudes will only take place after a lengthy educative process undertaken by groups such as the local churches, the South African Agricultural Union, the Rural Foundation etc. Secondly, it is the very fear of white farmers and their increasingly vulnerable position, that has contributed to a growing pattern of abusive behaviour against farmworkers. The strength of the opposition of hundreds of white farmers to the scrapping of the Land Acts was demonstrated in their march on the union buildings just after the announcement was made. Thirdly, the networks that have contributed - directly and indirectly - to the violence on the farms, such as the courts and police, are still firmly entrenched in the rural areas. For these reasons, a campaign against against farmworker abuse is more pertinent than ever before. We are calling for several steps to be taken. , Revised Edition

- Description: Non-profit organisations (NPOs) contribute to our society by addressing needs through value-creation activities which are normally not addressed by normal for-profit organisations. These NPOs generate their income through donations, fundraising and market activities such as the sale of products or services. However, in the pursuit of organisational sustainability, these NPOs need to ensure that their income meets their expenditure needs over the long run, to allow continuous value creation and to pursue their mission. An organisation’s business model can be visualised through a business model framework (BMF), which have been illustrated to be useful tools for organisations to test new business models, plan and coordinate activities, and to communicate how an organisations business model works to stakeholders. The use of BMFs by NPOs may be useful for similar purposes. However, a key challenge for NPOs and their management is adapting for-profit tools to be more applicable to the NPO environment. Whilst there has been some progress within the literature on adapting these for-profit business model tools to NPOs, this area of research is relatively underrepresented in the literature. The single case study method, exploratory in nature, following a deductive approach with a theoretical framework was used to evaluate the NPO Business model framework for NPOs with multiple income streams (Sanderse, 2014) appropriateness for the Centre for Biological Control (CBC), a mission-driven research organisation located within Rhodes University. The study made use of an interpretivist paradigm through the lens of resource-based theory. The contextual environment of the CBC was similar to other NPOs in that their organisational sustainability was at risk due to uncertainty about the availability of long-term funding. The CBC is actively diversifying their income streams by establishing new partnerships, which increase the capacity and resource base of the organisation to improve its flexibility in meeting current and potential funders’ needs. The NPO Business model framework for NPOs with multiple income streams was found to be a suitable BMF to visualise the holistic operations of the CBC. However, the role of governance-related matters being represented in this BMF was found to be lacking. An amended framework including governance as part of the Business model framework for NPOs with multiple income streams was developed. This improved the BMF, by allowing for further contextual insight into the CBCs business model as governance played a major role in the key activities and income-generating strategies they participate in. The role a BMF has in assisting an organisation with resource management activities was also explored. A suitable BMF, which allows for a holistic and explicit display of an organisation’s business model, would assist in determining how resources could be better managed or orchestrated to pursue different potential income-generating strategies or improve the efficiency of how resources are used in the current business model. This study contributed to business model theory by further testing the Business model framework for NPOs with multiple income streams as a tool to visualise an NPOs business model and identifying that once the governance block was added, this BMF became more suitable within the CBCs context. A minor contribution to resource based theory was the exploration of the potential roles BMFs play in resource management, which should be further investigated in line with additional research questions proposed. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2023

- Description: The real estate transaction process has been described as inefficient and technologically outdated due to numerous stakeholders and predominantly paper-based operations. Despite the apparent bottlenecks in the current process, the implementation of new technology into the real estate sector has lagged. Several attempts have been made to modernise and digitise the business process but committed integration of assisting technology has lacked attention. This study examined the applicability and potential integration of blockchain technology into the business process of South African real estate transactions. Blockchain’s novelty means that research in this space, especially within South Africa, is limited. Of the research that has been conducted, no models of the business processes for South African or blockchain-based real estate transactions have been constructed. This study provides two business process models, illustrating the two different processes. The main contribution of this paper was an integrated business process model, illustrating how the various processes and stakeholder interactions for South African blockchain-based real estate transactions are conducted on one transaction platform, common to all participating stakeholders. This platform was named the South African Blockchain Land Exchange System (SABLES), which manages and facilitates these transactions in their entirety from start to finish. This model depicts an enhanced business process that provides increased security, transparency, and speed. These benefits will be realised by those who register, adopt, and transact on the platform. Through in-depth interviews, the integrated business process model was assessed. The findings produced a final and combined thematic map, representing the main themes of the analysed interview data, namely blockchain implementation strategies, business process applicability, information technology assimilation, current transaction context, and PropTech 3.0 success factors. The discussion revealed that the current transaction process lacks technological innovation, which increases pressure on the conveyancing role. It was also revealed that there is not only a need within the industry, but a desire, for newer technologies to assist the transaction process. In order to streamline and improve efficiency, business processes should leverage digital records and data, and strive for a solution beyond digitisation, achieving digitalisation. Digitalisation recognises digital documents as official and legal documents as opposed to simply being digital back-ups. This, coupled with the business process models, represent theoretical contributions.

- Description: In this article, I use the capability approach to explore the role that the science, mathematics and technical subjects (SMTs) teacher education curriculum can play as a ‘gender conversion factor’. This comes amidst evidence that a major hindrance to the participation of girls in these disciplines is a lack of gender responsiveness in the pedagogy applied in schools. Seven teacher educators, who were purposively sampled at a Technical Teachers’ College in Zimbabwe, were the research participants. I adopted a case study design in which I used in-depth interviews, focus-group discussions and document analysis to generate data. Data was analysed deductively using predetermined themes based on an analytical tool anchored on Sen’s two, but quite distinct, aspects of freedom, that is, the opportunity aspect and the process aspect of freedom. The findings reveal that there is a limited awareness of gender issues among teacher educators, and that these issues are not being transformed into curriculum practice. All in all, it is evident that curriculum practices of SMTs teacher educators are riddled with gender blindness and so trainee teachers graduate from college without the necessary agency to deal with personal, social and environmental conversion factors that can play a role in girls converting the curriculum into functionings (beings and doings) and wider freedoms and valued beings and doings (capabilities).

- Description: Interest in mobile government (m-government) is growing globally. Mobile government refers to the use of wireless and mobile technologies to deliver services to citizens, businesses, employees and other government entities. Presently, technological advancements take place despite questions on whether the existing policy and regulatory frameworks are suitable to regulate the effects of m-government. With m-government, municipal operations take place in virtual spaces where the consequences of such operations are still largely unknown and the frameworks that are apt to minimise any long-term effects on society are yet to be defined. This conceptual article suggests that ethical frameworks should be encouraged as part of mobile government implementation in municipalities to encourage reflective municipal practices and to improve judgement and behaviour in m-government decision-making. It contributes to debates on approaches to comprehensively support and guide mobile government towards positive municipal service delivery outcomes.

- Description: Swahili, a national and official language in Kenya, is in wide use in the country as an inter-ethnic medium of communication and, generally, as a lingua franca. The operative language policy for lower primary–up to grade three–provides for the use of languages of the catchment as languages of instruction. The languages of the catchment refer to the more than 42 indigenous languages spoken in the country. The purpose of this study was to determine and discuss institutional and extra-institutional factors that might favour adoption of Swahili as the best medium–in the current sociolinguistic realities–in the ‘language-of-the-catchment-based’ literacy learning in Ekegusii-speaking areas of western Kenya. Data were obtained through classroom observations, teacher and church leaders’ interviews, observation and analysis of language trends at church worship services, and critical literature review.

- Description: Boat-based whale-watching (BBWW) is a rapidly growing marine tourism industry globally and in South Africa (SA). BBWW in SA was established in 1998, and since then the number of permits available has doubled from 20 to 40. However, the establishment and past growth of the industry was undertaken without ecological research or impact assessments. Global research has shown that BBWW has the potential to cause short-term changes in cetacean behaviour and movement, which in turn can have long-term population-level consequences. National policies to grow ocean economies in SA may encourage excessive growth in the BBWW industry, impacting the ecological sustainability. In the absence of long-term impact data, the BBWW industry should be managed to minimise short-term changes. This study aimed to determine the social and ecological status of the SA BBWW industry, using Plettenberg Bay as a case study, to inform its long term sustainability. To achieve this aim: 1) the short-term behavioural and movement responses of six cetacean species to encounters with commercial BBWW vessels were measured; 2) the efficacy of three permit regulations (approach speed, approach angle, and encounter duration) to prevent short-term behavioural changes in three cetacean species was measured; 3) rates of compliance of BBWWoperators with current regulations were recorded; 4) BBWW tourists’ expectations of and satisfaction with the industry were investigated; as well as 5) operators’ views on the current permit regulations of the industry All research was conducted between September 2018 and November 2020 in Plettenberg Bay (SA) where two BBWW companies operating two vessels each are active. Three dolphin (bottlenose, common and humpback dolphins) and three whale (Bryde’s, humpback and southern right whales) species are targeted by the industry, and were encountered during this study. , Thesis (PhD) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: This study set out to explore and describe in the form of a qualitative case study, an iteration of a Fundisa for Change teacher professional development programme, in this case the Teaching Life & Living short course presented to seventeen teachers as part of their Advanced Certificate in Teaching (ACT) Senior Phase Natural Sciences, at the University of Cape Town. The focus of the research was on describing how the development of teacher environmental pedagogical content knowledge (PCK) was supported and constructed in the course. The Consensus Model of Teacher Professional Knowledge and Skill, an outcome of the 2012 PCK Summit, was used to define the concept of PCK and also contributed the concept of amplifiers and filters as processes that mediate the development of teacher PCK. The study drew on Borko’s (2004) model of a professional development system, using the elements of course, teachers, facilitators and context as an analytical framework. Data generated included a teacher contextual profile questionnaire, audio-recordings of group work, course outputs and reflection and evaluation forms. Data analysis had two phases: the first phase concentrated on the development of analytic memos based on particular data sources whereas the second phase worked across data sources to present the evidence relating to each of the professional development system elements. The study found that teachers were supported in the development of their environmental PCK by the collaborative learning opportunities afforded by the course. Emergent PCK was organised according to five components: assessment knowledge; pedagogical knowledge; content knowledge; knowledge of learners; and, curricular knowledge. Emergent teacher learning ranged in specificity from general, to subject-specific, to domain-specific, and lastly to topic-specific knowledge. Teacher beliefs and orientations, prior knowledge and contexts brought into the professional development system were described as amplifiers and filters to teacher learning of PCK. In particular there were several contextual factors that emerged as themes from the data that had potentially filtering effects. Recommendations included that facilitators create an atmosphere conducive to collaborative learning, that evidence of learner conceptual understanding be examined during the course, that teachers be exposed to in-depth examples of canonical PCK and that more modelling of formative assessment strategies are presented.

- Description: Jeffrey Lionel Dahmer is an infamous serial killer and cannibal. He was described as a normal, but shy little boy, yet developed into an adult who brutally murdered, engaged in necrophiliac acts, dismembered and ate parts of his victims. This study took the form of an intrinsic case study with the aim to explore and describe the personality development of Jeffrey Dahmer. This exploration examined Dahmer’s known childhood experiences through the theoretical perspective of Otto Kernberg’s (1974, 1975, 1976) Object Relations Theory, in order to understand how Dahmer’s personality was formed. Data was collected from multiple resources, including books, authoritative biographies, academic articles, and internet sources available in the public domain. It was analysed using Miles, Huberman, and Saldaña’s (2014) three-step process namely, data condensation, data display, and conclusion drawing and verification. This study’s findings confirmed the formation of pathological behavioural patterns supported by primitive defence mechanisms, associated with Kernberg’s lower level pathologies. It reflected Dahmer’s pathological formation of psychic structures seen in a diffuse identity and impaired formation of the superego, that supported these patterns. Additionally, the research was valuable in enhancing the researcher’s insight into personality development according to Kernberg’s Object Relations Theory. This study may also be beneficial to practising clinicians and professionals as an example of the early identification of personality pathology. , Thesis (MA) -- Faculty of Health Sciences, 2021

- Description: This research project constituted as a thesis of limited scope for a Masters in Education Degree (i.e. as 50% of the degree) focusses on a job creation programme named ‘Groen Sebenza’ [Green Work]. Groen Sebenza is an environmental education ‘incubator’ programme driven and implemented by the South African National Biodiversity Institute (SANBI) to unlock green jobs and bridge the gap between education and job opportunities in the biodiversity sector in South Africa. The programme is a key intervention to strengthen biodiversity human capacity development in the biodiversity sector in South Africa, seeking to contribute to transformation of the biodiversity sector, and also address issues of youth unemployment in the country. The young ‘interns’ in the programme were called ‘pioneers’ at the start of the project. This research project explores how a host institution operating as a community of practice within a landscape of practice managed to implement the Groen Sebenza programme by absorbing and appointing all their pioneers into sustainable jobs beyond the pilot project. I sought to better understand the process of supporting and empowering unemployed youth into sustainable green jobs within the Groen Sebenza partnership programme. I drew on Community of Practice (CoP) theory, and its value creation framework to develop this understanding, and I under-laboured the analysis with a social realist analysis of enabling and constraining factors. The unit of analysis of a Community of Practice was a useful focus for the study, as these mentors, managers, and administrators were all involved in supporting the empowerment and retention of the young pioneers in the host institution. To develop deeper insight into the learning and knowing, and value created in and by the Groen Sebenza CoP in the Host Institution, I also sought insight into enabling and constraining factors and how these shaped and contributed to empowerment and retention of the pioneers in sustainable green jobs. The research addressed the main question of ‘How do processes of learning, knowing and value creation contribute to empowerment and retention of unemployed youth in a successful Host Institution in the Groen Sebenza programme, and what enabled or constrained the empowerment and retention processes and outcomes?’. Three sub-questions were used in the study, which focussed on the mentoring, training and workplace experiences and how they contribute to the process of learning and knowing within the Groen Sebenza Community of Practice in the Host Institution? [Addressed in Chapter 4], the value creation elements that emerged in the implementation of the programme in support and empowerment of the pioneers in the Host institution’s Groen Sebenza CoP? [Addressed in Chapter 5], and the enabling and constraining factors that shaped and contributed to the uptake of the Pioneers into sustainable green jobs at the Host Institution within the Groen Sebenza Programme? [Addressed in Chapter 6]. The research was conducted as a qualitative case study, in which I used semi-structured interviews as a key data source, as well as document analysis, and a questionnaire. The study drew on inductive, abductive and retroductive modes of inference since I sought to explore an understanding of the practices and learning that occurred that contributed and led to the successful uptake of Pioneers into jobs, as well as the enabling and constraining factors. The study was interpretive at the epistemic level, and had a social realist under-labouring at the ontological level. Key findings of the study point to the development of enabling cultures of mentoring in workplaces, and the provision of a diversity of workplace learning experiences including formal training. It also points to the importance of personal emergent properties amongst mentors and pioneers that embrace a willingness to work together and build strong relationships, and to learn together. Learning in the community of practice was shown to develop identity and a sense of belonging as pioneers were given meaningful tasks to do and their training and interactions with mentors was experienced as meaningful and relevant. The contributions of the pioneers to the institutional mandate was appreciated by the mentors and therefore also well supported within an empowerment orientation. Various structural factors contributed to this enabling situation, most notably strong support from management as well as good co-operation across divisions. Constraining factors included the physical distances in the province, as well as financial and technical issues such as poor ICT communication systems. Overall, though the study showed that a strong approach to learning in communities of practice supported by empowering mentoring can lead to the integration of young pioneers into sustainable green jobs in the environmental sector. A whole institution approach to this process is, however, needed, and the organisation needs to develop a culture of social learning. As recently as September 2020 as this study was being finalised, the Presidential Employment Stimulus Plan (Office of the President, 2020) following the initial economic shocks emanating from the COVID-19 pandemic, made yet another commitment to using the Groen Sebenza model to create and support sustainable job creation for young people in South Africa today in the environmental sector. This study has been developed and designed to understand those processes and enabling conditions that can support retention and empowerment of young people to take up jobs in the environmental sector today. Its recommendations may therefore be of value to those involved in seeking to support sustainable impacts in terms of retention and employment in programmes such as the Groen Sebenza, and in the Groen Sebenza programme itself as it continues to unfold as a key job creation tool for unemployed youth. , Thesis (MEd) -- Faculty of Education, Education, 2021

- Description: A change champion has been defined as a person from any level of the organisation who is skilled at initiating, facilitating and implementing change, and who can effectively champion organisational changes. From a review of the literature, it was anticipated that change champions may experience role conflict, due to the multiple roles that they needed to fulfil simultaneously. Informed by organisational role theory, this research investigated the change management programme of a specific public entity as a case study, and analysed the nature of the role conflict that change champions experienced during a specific organisational change. Semi-structured interviews were conducted with four change champions, the change coordinator and the Executive Director Corporate Services. The organisational documents that relate to change management were also consulted with a view to providing background information and an overview of the change management programme. A deductive thematic analysis approach was used to analyse the data. A coding framework was developed prior to the collection of data, and was used for the identification of theoretical codes and themes in the data. The following codes were developed and explored as types of role conflict: role ambiguity, person role conflict, role strain, role overload and role incompatibility. In terms of the findings, this study confirmed that change champions did experience role conflict during organisational change, mainly due to various expectations that come from different role senders. In the light of these findings, it was recommended that senior managers could reduce the incidents of role conflict by training change champions, introducing an orientation programme for new change champions, consider their personal values when appointing them, and allocating sufficient time for change champions to fulfil this additional role. This study has contributed to the body of knowledge by drawing on role theory and applying it to change management, in order to provide insight on the role of change champions during the organisational change, and in particular the role conflict that they experienced.

- Description: A change champion has been defined as a person from any level of the organisation who is skilled at initiating, facilitating and implementing change, and who can effectively champion organisational changes. From a review of the literature, it was anticipated that change champions may experience role conflict, due to the multiple roles that they needed to fulfil simultaneously. Informed by organisational role theory, this research investigated the change management programme of a specific public entity as a case study, and analysed the nature of the role conflict that change champions experienced during a specific organisational change. Semi-structured interviews were conducted with four change champions, the change coordinator and the Executive Director Corporate Services. The organisational documents that relate to change management were also consulted with a view to providing background information and an overview of the change management programme. A deductive thematic analysis approach was used to analyse the data. A coding framework was developed prior to the collection of data, and was used for the identification of theoretical codes and themes in the data. The following codes were developed and explored as types of role conflict: role ambiguity, person role conflict, role strain, role overload and role incompatibility. In terms of the findings, this study confirmed that change champions did experience role conflict during organisational change, mainly due to various expectations that come from different role senders. In the light of these findings, it was recommended that senior managers could reduce the incidents of role conflict by training change champions, introducing an orientation programme for new change champions, consider their personal values when appointing them, and allocating sufficient time for change champions to fulfil this additional role. This study has contributed to the body of knowledge by drawing on role theory and applying it to change management, in order to provide insight on the role of change champions during the organisational change, and in particular the role conflict that they experienced.

- Description: This research investigation is based on continuous improvement changes arising from - and related to - ISO 9001 implementation at Sundays River Citrus Company (SRCC), which is one of the biggest packers, marketers, and exporters of citrus fruit in South Africa. The Board of SRCC adopted ISO 9001 to ensure organizational efficiency and sustainability while improving quality control, customer service, teamwork and leadership. However, research indicates not all organizations that have Implemented ISO 9001 realize the intended benefits. While no research was available on the citrus agriculture industry, research in the tourism industry indicates that not only did some companies not realize the expected benefits, but also incurred substantial investment costs. It is estimated that approximately thirty to ninety percent of change initiatives fail to meet their objectives, and research studies also indicate that middle managers play a critical role that can influence the outcomes of a change project. However, Balogun (2003) indicates that middle managers play a complex role and are exposed to role conflict, which can influence the outcomes of change initiatives. In this context, this research study aimed to investigate the role conflicts experienced by middle managers during the process of an ISO 9001 continuous improvement change. The study draws on role theory, applying it to their management of change. The following role conflict types were investigated: (1) intra-sender conflict, (2) inter-sender role conflict, (3) inter-role conflict, (4) role ambiguity and (5) role strain. The research approach is qualitative, and has adopted a post-positivist paradigm, utilizing a deductive qualitative method. The study adopted a case study approach. Data was gathered mainly from interviews and supported by organizational documents. Semi structured interviews were conducted with questions formulated through the use of the coding manual (See Appendix C) to ensure alignment of data collection with the research propositions derived from literature. A deductive thematic analysis method was used to analyze the interview data. The research findings confirmed that during continuous improvement change, as middle managers strived to satisfy the incompatible expectations of role senders (mainly senior and junior managers), they experienced the five role conflict types. The study findings also indicate that middle managers experience conflicts due to the incompatible expectations of other role senders such as quality and marketing departments. The findings suggest that middle managers are managing these conflicts, but notes that they do require some assistance and support from senior management. The study concludes with managerial and research recommendations. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2023

- Description: Publisher version , Reconciling conservation and social justice imperatives is a major challenge facing many postcolonial states worldwide. Where historically disenfranchised communities have laid legal claim to protected areas, the typical resolution has been collaborative management agreements between the state and claimant communities. The real outcomes of such strategies for people and ecosystems have been seriously questioned, although alternative approaches are seldom explored. Here, we reflect on one such alternative that was pursued in a case in South Africa, where the land was handed back to the community and a replacement protected area created. Our objective was to explore the opportunities and trade-offs associated with this approach for communities and conservation agencies alike, and to compare these to typical collaborative management outcomes. Methods included key informant interviews, focus group discussions and household surveys. We find that, surprisingly, this approach created more benefits for the conservation agency than for claimant communities. Indeed, the community experiences bore a striking resemblance to those experienced in collaborative management settings: intra-community conflict, confusion over leadership and serious questions about the boundaries of the “community”. Processes aimed at redressing past injustice in disputes over conservation land, regardless of the approach adopted, must bring with them a strong commitment to building institutional and leadership capacities within communities, and pay serious attention to the ways in which equity and social justice can be fostered after the settlement of a land claim. Settlement agreements are frequently treated as the final step towards social justice, but are in fact just the beginning.

- Description: This case study research on the effect of leadership on organizational culture, is based on a small luxury tourism organization – Belmond Safaris – based in Maun, Botswana. The study set out to determine critical incidents that occurred during the tenure of the current general manager with the intention of uncovering her leadership behaviour and how it has shaped the culture of the organization. The literature review identified quantitative and qualitative approaches to researching organizational culture, but settles on Schein’s theory of organizational culture (Schein, 1992; 2010) as the approach adopted in this study. Furthermore, it reviews the various roles of strategic leaders and how these affect the culture of the organization. The study follows a qualitative methodology and applies the Critical Incident Technique to explore how, as a leader, the behaviour of the general manager shaped the organization’s culture. Data triangulation is achieved through the use of multiple sources – interviews, analysis of company documents and the examination of minutes of management meetings. Following the fieldwork, the evidence within the findings of the study required a theoretical reorientation and a shift from strategic leadership to a new focus on relational leadership, highlighting the prominence of social exchanges between the general manager and employees, as opposed to economic exchanges. The study concludes by acknowledging the limitations and delimitations of the study, which include time constraints as well as the deliberate exclusion of certain participants (e.g. camp managers) from the study. In its conclusion the study also presents recommendations for future studies. The researcher recommends a broader study within the tourism industry, as well as a larger and more inclusive sample size, in order to obtain better insights into the study of culture and leadership within organizations.

- Description: This research was a case study of responsible leadership in a renewable energy organisation in the Eastern Cape. The study aimed to understand and describe how a renewable energy organisation applies responsible leadership to build trust. The four objectives of the study were namely to: (1) describe how the organisation interacts with its stakeholders to build trust; (2) understand how the members of the organisation demonstrate the characteristics of responsible leadership; (3) understand how different stakeholders perceive and experience the interaction of the company with established stakeholders; (4) make recommendations that a renewable energy organisation can exercise the characteristics of responsible leadership to develop its stakeholder engagement framework. In the study the stakeholder theory was applied as the theoretical framework, and the theory encourages organisations to determine the "power, legitimacy, and urgency" of stakeholders with whom they interact. A qualitative approach was used in this study. The data collection method was semi-structured interviews for all 12 participants. Data were analysed through a deductive thematic approach to identify, analyse and report patterns or themes within the data collected. The study showed that the wind farm unintentionally applies some components of responsible leadership among its stakeholders. Openness, transparency, and communication are critical actions that this organisation undertakes to cultivate trust among both its internal and external stakeholders. External stakeholders experience this organisation differently. There are mixed feelings regarding how the wind farm conducts its stakeholder engagement activities, particularly relating to landowners and government institutions. A stakeholder engagement framework is imperative if an organisation is to maintain cordial relations with its stakeholders. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2023

- Description: Floods occurred in the Ndlambe Local Municipality in South Africa in October 2012. During various stages of the post-disaster recovery, bacterial concentrations were measured in water and soil samples from the flood zone. All drinking water concentrations of E. coli were below 1–3 colony forming units per 100 millilitres (CFUs/100 mL). The flood waters contained between 46500 to more than 100000 CFUs/100 mL of E. coli. {The concentrations of Salmonella spp. in the flood waters varied from 5000 to 250000 CFUs/100 mL. The presumptive Vibrio spp. concentrations in flood waters ranged from 1000 to over 150000 CFUs/100 mL. {The soil concentrations for E. coli ranged from 1 to above 330 colony-forming units per 1 g of soil dry weight (CFUs/g). The soil concentrations of Salmonella spp. varied from below 1 to 22 CFUs/g. The estimated airborne fungal concentrations ranged from 16820 to 28540 colony-forming units per 1 cubic meter. An outbreak of an infectious disease was recorded among the volunteers who assisted with the post-disaster recovery. The likely bacterial causative agents included strains of Aeromonas spp. and Vibrio cholerae. Any human contact with either the contaminated flood waters or of flooded dwellings should only occur, if the individuals in questions are equipped with the full-body personal protective gear. Non-governmental stakeholders performed majority of the post-disaster recovery operations, as the local government could only cover 11% of the required costs. Applying sanitation funds to disaster recovery and increased use of the low-cost flood defence products in high risk areas could provide a solution for the future.

- Description: No formal study on the incidence and extent of medullated and coloured fibres has been performed in South Africa. The purpose of this research project was to investigate the validity of the claims that there has been an increase in the production of wool contaminated with medullated and coloured fibres. Therefore, the main aim of this study was to determine whether the incidence and extent of medullated and coloured fibres in the South African wool clip have changed over time. Secondly, the study aimed to determine whether the incidence and extent of medullated and coloured fibres have a distinct geographic distribution. This study explored eight years of wool production records (2010 to 2017) obtained from BKB, the largest wool broker in South Africa. For the purpose of this research, the wool-producing areas of South Africa were divided into 6 regions, according to average annual rainfall, vegetation type and major farming practices applied in the area. Statistical analysis of the data included descriptive statistics, analysis of variance and post-hoc tests, as well as regression analyses. This study succeeded in quantifying the extent and prevalence of contamination with medullated and coloured fibres in the South African wool clip. The overarching conclusions were: • Floating kemp is the most important contaminant of wool in South Africa, with the incidence of harsh kemp and coloured fibres being very low. • Generally, the most important areas that need attention in combatting contamination in the South African wool clip, are the Mixed Farming Summer Rainfall Region, the Semi-Arid Grassveld and the High Rainfall Grassland. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022
