- Description: South Africa is recognised as a country with unusually high levels of rape and sexual violence. The majority of those who experience sexual violence do not acknowledge, disclose or report it, and do not access support. Many factors have been identified which can inhibit acknowledgement and disclosure. While silence is to be honoured as a chosen response, unwanted silencing is of concern. The annual Silent Protest at Rhodes University is a day-long anti-rape protest which draws attention to the attitudes and practices which silence victim-survivors, and enacts solidarity with victim-survivors of sexual violence. I conducted a three year “critically engaged, activist ethnography” with the community of Silent Protestors and organisers. My focus was on the stories that victim-survivors told about the impacts of participating in the protest. Changes in the research context allowed for a participatory action research cycle to be incorporated into the methodology. This offered an opportunity to implement and evaluate some changes suggested by my research contributors. My contributor’s narratives highlighted the ways in which as a society we position those who have been subjected to sexual violence in ways that are limited and limiting and which diminish victim-survivors’ sense of agency and value. This malignant positioning restricts the choices available to victim-survivors. The anticipation of being positioned in negative ways can inhibit victim-survivors from disclosing a violation and accessing care and justice. Participation in the Silent Protest seems to stand against some of the factors which inhibit acknowledgement and disclosure. Through their participation many women took up opportunities to share their story with at least one other person and to receive and offer care. Most described participation as having been beneficial and having helped them move towards living well again. The ways in which the Silent Protest positioned victim-survivors and the choices they were offered in relation to that positioning seemed to open up opportunities for thinking, feeling and acting in ways that they preferred. This suggests that interventions which mobilise both political resistance and mutual care hold promise for developing more accessible and effective services to those affected by sexual violence. , Thesis (PhD) -- Faculty of Humanities, Psychology, 2023

'ORPHEIOI HYMNOI' The generic contexts of the Orphic Hymns

- Description: Uncertainty surrounds the circumstances of Orphic Hymns’ composition and their intended use. Their author has substituted their own identity for that of the mythological poet and there is no certain reference to the extant collection in any ancient source. They are, in this sense, decontextualised. This study aims to make a contribution to the ongoing debate concerning the hymns’ composition, and the original function they might have served, through an analysis of their poetic and generic contexts. Following a detailed survey of scholarship on the hymns, I reflect first on the collection as a unified text, the constitutive parts of the individual hymns and the methods they employ for addressing, describing and praying to the gods. I then study a select group of stylistic features that the hymns prominently display: their use of phonic effects, including etymological figures, of antithesis and symmetrical patterning, and their extensive repetition of poetic formulae. In each case I discuss the deployment and significance of these poetic elements within the collection and consider the intertextual parallels suggested by their recurrence in Greek literary texts of all periods. This analysis reveals the hymns’ engagement with an overlapping set of poetic traditions, including, most prominently, cultic hymns and oracles, gnomic poetry, the theological discourses of the Presocratic philosophers and, in particular, Orphic poetry in its many forms. It suggests moreover that the hymns engage deeply with the oral strategies of the earliest Greek poets, underscoring the conclusion reached by several recent scholars, that the extant collection is essentially performative and was intended to be recited and heard. I argue that the Orphic Hymns were not a unique text in their employment of the stylistic features studied here, but drew extensively upon earlier hymns composed in Orpheus’ name. I further consider, in the light of this argument, the bearing this study has on the unresolved questions of the hymns’ composition, whether by a single author or many, and the aims of the poet(s) who composed them. , Thesis (PhD) -- Faculty of Humanities, School of Languages and Literature Studies, 2022

- Description: Urbanisation is occurring on a massive scale globally and even more so in the less developed regions of the Global South including sub-Saharan Africa (SSA). Like other developing regions of the world, urbanisation in SSA is not occurring alongside a corresponding growth in urban economies. Resultantly, it is taking place in tandem with the rising scourge of urban poverty, including food insecurity. While urban food insecurity is a clear challenge in SSA, the challenge has however not been met with equal vigour in policy making and implementation circles and even in academia. Problematically, the urban food security literature often focuses on one element of the food system without giving due attention to other components of the system. Resultantly, broader systemic failures and the dynamics related to the different actors across the system-elements are missed. There has thus been recent calls to embrace urban governance in studying urban food systems, which this study does. The thesis examines the urban food system in Bulawayo (in Zimbabwe) with specific reference to urban governance and household food security to understand sociologically the complex multi-dimensional processes, structures, systems, and practices underpinning the urban food system. As a result of the complex nature of food systems, an eclectic analytical framework is employed encompassing Obeng Odoom’s DED framework, Clapp and Fuchs’ framework of power, Gaventa’s power cube and theories of everyday life derived from de Certeau and Lefebvre. Methodologically, the study is informed by a Critical Realism paradigm which accommodates the convergent mixed methods research design employed. The research strategy employed was that of a survey and case study. Key findings reveal that the Bulawayo food system, from production to consumption, is complex and is nested within broader national and international food systems. Although without a direct and explicit mandate on food security, the local authority is at the centre of urban governance processes as it employs a plethora of strategies to influence the nature of the food system. However, the study reveals that the food system is as much a construction from below through the agential activities of the urban poor. , Thesis (PhD) -- Faculty of Humanities, Sociology, 2022

- Description: This thesis examines the introduction and development of western medical practices in colonial spaces with particular reference to midwifery practices in colonial Ibadan, Nigeria, from 1893 to 1960. This has become necessary because of the importance placed on childbirth and maternal healthcare in the twentieth century. The trends and changes in midwifery and midwifery practices in colonial Ibadan are seen as reflections of other transformations in British African colonies at large. The study begins with a detailed historical analysis of the major metropolitan and local factors that informed the introduction and development of Western obstetrics in colonial Ibadan, Nigeria. It proceeds to examine the development of Western midwifery practices in colonial Ibadan; highlighting the contributions of the Ibadan people to the development of Western midwifery practices and emphasizing policies affecting development, and implementation of Western obstetrics. The thesis goes further to reveal the prejudiced nature of colonial medical policies, and the ways it shaped various responses especially from rural folks who were particularly marginalized since the 1920s when maternal healthcare policies was implemented in the urban areas till the 1950s when a reformed policy for rural medical service scheme was introduced to the rural folks. Thus, influencing the ways they imagined and appropriated ideas of western obstetrics alongside African traditional midwifery practices. The idea is to demonstrate in this thesis the extent to which the precincts in colonial medical policies, most especially the establishment of maternity hospitals, clinics and dispensaries, and the institutionalization of western obstetrics, inspired critical and ingenious responses from colonial doctors, colonial officials, the missionaries, patients, African trained midwives, traditional medical practitioners and the African population in general. Placing all of these historical events within a wider context, this thesis borrows insights from the social history of medicine in an attempt to reconstruct the colonial medical practices in Ibadan, Nigeria, through the sites of midwifery practices and maternal welfare services from 1893 to 1960. This is in addition to its dependence on a comparatively rich, but skewed historical evidence, including a plethora of annual medical reports, official reports of the department of medical and sanitary services, official correspondences within the colonial government in Ibadan and Nigeria, and between the colonial government and the colonial office in the United Kingdom. Details of African responses to medical policies were garnered from oral testimonies, newspaper publications and correspondences between the African public and the colonial government in Ibadan. In exploring this historical evidence, the thesis reveals very interesting details of colonial perceptions about African health and their underlining motives for introducing western medical ideas, the various medical schemes and policies used in driving colonial interest and the ways Africans imagined, re-imagined, and appropriated Western medical practices. , Thesis (PhD) -- Faculty of Humanities, History, 2022

- Description: This thesis seeks to understand the social and cultural experiences of Zimbabwean teachers, as foreigners, in KwaZulu-Natal townships, and KwaZulu-Natal township secondary schools, in South Africa. It examines the ways in which Zimbabwean teachers negotiate the social, cultural, and institutional milieu of KwaZulu-Natal townships and secondary schools. In doing so, the thesis draws upon social interface theory, as this theory facilitates an examination and understanding of the ways in which the Zimbabwean teachers interpret the spaces (and lifeworld) of South Africans and, simultaneously, navigate their way in and through these spaces along social and cultural interfaces. While the focus is on the perspectives and practices of the Zimbabwean teachers, the thesis recognises and shows that their socio-cultural experiences are constituted and configured in significant ways by their daily encounters with South Africans. The fieldwork for the thesis involved primarily in-depth interviews with thirty Zimbabwean teachers residing in six selected KwaZulu-Natal townships (and teaching at six different secondary schools), as well as fifteen South African teachers, five school administrators and thirty other South African citizens. The sample of Zimbabwean teachers was stratified in relation to the different townships, as well as gender and the number of years teaching in South Africa, so as to investigate whether and how these variables may configure the socio-cultural experiences of these teachers. A consideration of variation in the number of years of teaching in South Africa in particular allowed for an examination of possible shifts in socio-cultural experiences over time, as negotiation along interfaces is an ongoing and contingent process. The findings demonstrate a range of experiences and challenges faced by Zimbabwean teachers in KwaZulu-Natal (with regard to both township and school life), some of which they share with South African teachers but many of which are unique to them. At the same time, there are important differences amongst Zimbabwean teachers in relation to how they interface with South African citizens and teachers. While some teachers negotiate local spaces through active socialising and assimilating into the lifeworld (township life of South Africans and the institutional culture of township schools), other teachers move through the space by way of isolation, withdrawal, and alienation. In general, in terms of adjusting to the lifeworld of South Africans in KwaZulu-Natal townships and schools, Zimbabwean teachers pursue different routes which, in the end, made sense to them and about which they express some degree of personal comfort. , Lo mbhalo wobuhlakani uzama ukuqonda inhlalo kanye namasiko abahlangabezana nako othisha baseZimbabwe njengabantu bokufika emalokishini akwaZulu-Natal, kanye nasezikoleni zamabanga athe thuthu zasemalokishini akwaZulu-Natal eNingizimu-Afrika. Uhlolisisa izindlela labo thisha ababonisana ngazo ngamasiko kanye nenhlalakahle yasezikoleni zasemalokishini akwaZulu-Natal. Ngokwenzanjalo, lo mbhalo udonsa umhlahlandlela wenhlalakahle nokuhlangana ngoba ukungena kwabo endaweni yakwaZulu-Natal, labo thisha bahumusha indawo baphinde babonisane bachushisane ngenqubekela phambili yabo nangenhlalo namasiko abahlangabezana nawo. Ukuhlanganisa othisha baseNingizimu-Afrika nezakhamuzi kumele kusebenzisane ngokulingana. Abahlangabezana nakho kwakhiwa ngokubambisana phakathi kwabaseZimbabwe kanye nabaseNingizimu-Afrika ukuze izwi labaseNingizimu-Afrika lingagqibeki ngoba sekunakekelwa kakhulu abseZimbabwe. Umsebenzi wasensimini walo mbhalo wobuhlakani uhlanganisa ucwaningo kothisha abangani-30 baseZimbabwe abahlala ezindaweni ezingu-6 ezikhethekile ezisemalokishini akwaZulu-Natal, nothisha abayi-15 baseNingizimu-Afrika kanye nabaphathi bezikole abayi-5. Kubuye kwenziwa ucwaningo kwizakhamuzi ezingama-30 zaseNingizimu-Afrika. Isampula lihlanganiswe ngokubuka indawo lapho aphuma khona umuntu, kanye neminyaka aseyifundisile eNingizimu-Afrika. Ucwaningo lubukisise kakhulu indlela ababuka ngayo inhlalakahle namasiko kube kubukisiswa nenani leminyaka aseyifundisile umuntu ngamunye ukuze kuhlolisiswe izinguquko zokuxoxisana ezidalwe yisikhathi asihlalile umuntu phakathi kothisha abasebancane nalabo asebekhulile. Imiphumela yocwaningo iveza iznselele ezahlukene ababhekene nazo othisha baseZimbabwe njengoba bengabahlali baseNingizimu-Afrika. Ezinye zalezi nselele ziqhamuka ngokwehlukana kwemiphakathi kwabaseZimbabwe kanye nabaseNingizimu-Afrika. Ngokunjalo kunomehluko obalulekayo kothisha baseZimbabwe mayelana nendlela ukuxoxisana nokubonisana okuqhubeka ngayo. Kukhona labo ukungena bathi khaxa emiphakathini nasezimpilweni abakuzo eNingizimu-Afrika nasezikoleni abakuzo namasiko nenhlalakahle yakulezo zindawo ngakolunye uhlangothi abanye othisha bazithole bephila njengenhlwa bephila ngabodwana eNingizimu-Afrika. Kodwa ekugcineni kwakho konke, lolu cwaningo luthola ukuthi othisha baseZimbabwe ezikoleni zasemalokishini akwaZulu-Natal lapha eNingizimu-Afrika bazakhela impilo eyenza umuntu ngamunye azizwe ehlaliseke kahle eNingizimu- Afrika ngendlela ephelele nethokomalisa yena ngo kwakhe. , Thesis (PhD) -- Faculty of Humanities, Sociology, 2022

- Description: Freshwater fishes are in global decline and fish as a group are the most imperilled of all vertebrates. Freshwater systems are among the most threatened globally, largely owing to their comparatively high species and habitat diversity while occupying a minute fraction of the Earth’s surface. In South Africa, invasion by non-native fishes has had a devastating effect on freshwater systems across the country. Numerous other stressors and anthropogenic impacts continue to impact these systems, including habitat degradation, water abstraction and global change effects. In general, South African freshwater systems are under-studied and there is a lack of baseline biological and ecological studies on many freshwater fish species. The Cape Fold Ecoregion (CFE) of South Africa is a particularly vulnerable region, with many range-restricted species and highly fragmented native fish ranges following high invasion rates. Within the CFE, the Olifants-Doring River System (ODRS) is of primary concern owing to the high endemism and imperilled status of its freshwater fish species. The Rondegat River in the ODRS is of notable conservation value, as it hosts populations of important endemic CFE species. This river is unique, being the site of the first alien fish eradication programme of its kind in South Africa. Thus the Rondegat River, and in particular its imperilled cyprinid assemblage, is used here as a case study of the responses and community dynamics of recovering freshwater fish species. The members of this cyprinid assemblage are Sedercypris calidus, Pseudobarbus phlegethon and Labeobarbus seeberi. Sedercypris calidus and L. seeberi are listed by the International Union for the Conservation of Nature (IUCN) as “Near-Threatened”, while P. phlegethon is listed as “Endangered”. Understanding the dynamics and responses to understudied vulnerable fish communities in the wake of restoration efforts was the overarching goal of this thesis. The first chapter served as a review of current knowledge of the CFE, the Rondegat River, the myriad stressors that have impacted on or are projected to affect this region, and the freshwater fish species on which those stressors act. My first investigations served as an extension of the existing Rondegat River monitoring programme, making use of remote underwater video (RUV) data to assess relative abundance and habitat associations of the focal species (Chapter 2). A relatively limited spatial range of P. phlegethon was established, which was suggested to be a result of relatively highly specialised habitat requirements and sensitivity to disturbance. Sedercypris calidus was confirmed as a relatively more abundant and ubiquitous species across the length of the Rondegat River, sharing much of the lower and middle reaches with L. seeberi. I sought to use experimental trials of functional response, as a proxy for feeding performance, across representative temperatures and relevant prey types, in the spatially overlapping S. calidus and L. seeberi (Chapter 3). Labeobarbus seeberi generally outcompeted S. calidus across temperature treatments and prey types. The ecomorphology and diet of all three species were used to construct trophic profiles, which suggested that there was a high degree of feeding capacity overlap between L. seeberi and S. calidus, while P. phlegethon diverged from the other two species (Chapter 4). Gut content suggested that all three species overlapped broadly in diet. This indicated that the realised trophic niche of these species is similar, despite some morphological specialisation. I then used RUV data to investigate in-situ feeding behaviours, with the aim to disentangle the nuances of community dynamics and mechanisms of coexistence in the cyprinid assemblage (Chapter 5). I found that, despite the higher feeding performance of L. seeberi (Chapter 3) and its overlaps in diet and feeding capacity with S. calidus (Chapter 4), S. calidus is able to mitigate competitive pressures through foraging mode switching and exploitation of allochthonous food inputs. Evidence for further habitat and prey selectivity in Pseudobarbus phlegethon was gathered based on dependence on complex habitats and pool refugia for the majority of its feeding, supporting this species as a headwater specialist; alongside signals of its spatial and habitat use patterns (Chapter 2). While S. calidus and L. seeberi were found to be less habitat-specific than P. phlegethon, caution was noted in the potential for ongoing stressors, such as habitat destruction, loss of river connectivity and global change effects, to impact on the reproductive success of these two species. Stressors affecting the habitats and sensitive invertebrate taxa upon which all three species depend continue to threaten the Rondegat system, highlighting the need to maintain ecosystem integrity through conservation interventions. There remains significant scope to maintain restoration efforts in the Rondegat River and other river systems of the CFE, through direct conservation actions, enhanced community awareness, indigenous riparian vegetation restoration and involvement of local stakeholders in various conservation-centred activities. , Thesis (PhD) -- Faculty of Science, Ichthyology and Fisheries Science, 2022

- Description: Extract from Introduction: “In the cover bands I worked with, I used to do what all my colleagues in these bands were doing to learn and remember repertoire; transcribe “by ear” and then rehearse with the whole band. Later, when I joined “909” [a cover band named after the “909” model of drum-box developed and built by the Japanese company, Roland] I learned to extend that skill by notating my transcriptions and then playing from these self-made keyboard parts. All the instrumentalists in that band likewise played from their own notated transcriptions and, from that time onward it became rarer for me to do any kind of performance work without a set of self-made parts to read from or refer to. I had thus reverted to performing from musical notation. Even later, when I became involved almost exclusively in improvisational music performance, I never quite abandoned the notion of having notated keyboard or piano parts to hand, as a reference or guide. Since about 1990, I have led a life that has increasingly left pop music behind and instead embraced working with improvising musicians; those who wish to explore South African folk idioms in their compositional and performance output, as well as others who have a deep love of jazz music. At the same time, I have re-entered the realm of classical music and music-making; often through writing arrangements of my own music, which would incorporate classically trained players, as well as in response to commissions to compose [for particular musicians or groups of musicians] fully notated pieces of music – such as the works in this PhD portfolio. Yet, there are many circumstantial factors that feed into my composing, and exert an influence on my creativity. A major step in this particular direction came during 2002 when composer, Michael Blake, asked me to contribute to The Bow Project. This commission brought me into close contact with the [then intact and very active] Sontonga Quartet. Several further requests for, and commissions of, new works followed on from there. Two such works constitute the major portion of the portfolio to which these reflexive commentaries refer.” , Thesis (PhD) -- Faculty of Humanities, Music and Musicology, 2022

- Description: Type 2 diabetes mellitus (T2DM) and cancer are major non-communicable diseases causing a heavy morbidity-mortality and economic burden globally. The therapeutic efforts in managing these diseases are primarily chemotherapeutic and are associated with demerits, including side effects and toxicity, limiting the prescribed amounts. These dosage limits may cause drug resistance, another major challenge in maintaining quality global health. The pursuit of novel natural bioproducts is a reasonable strategy to add to the arsenal against T2DM and cancer. Fucoidans, sulphated fucose polysaccharides abundant in brown seaweeds, have recently become popular for their biological activities, including anti-diabetic and anti-cancer properties. However, endemic South African brown seaweeds have not been adequately explored. Therefore, this study sought to characterise fucoidans extracted from South African brown seaweeds and elucidate their structure to their biological activities. Also, this study highlighted carbohydrate and glucose metabolism as major target processes in the control efforts of T2DM and cancer using fucoidans. Harvested brown seaweeds were identified as Ecklonia radiata and Sargassum elegans. E. maxima was kindly donated by KelpX. The fucoidans were then extracted using hot water, EDTA assisted, and acid extraction protocols. The integrity of the extracted fucoidan was confirmed through structural analysis using FTIR, NMR and TGA. The fucoidan extracts were then chemically characterised to determine their carbohydrate and monosaccharide composition and sulphate content. The characterised fucoidans were profiled for inhibiting the major amylolytic enzymes, namely α-amylase and α-glucosidase. The mode of inhibition by fucoidans and synergy experiments with the commercial anti-diabetic drug acarbose were also investigated. Furthermore, the fucoidans were screened for potential anti-cancer activities on the human colorectal HCT116 cancer cell line. The cytotoxicity of fucoidans was quantified using the resazurin assay. The effect of fucoidan on HCT116 cell adhesion on the tissue culture plastic was also investigated using the crystal violet-based cell adhesion assay. In addition, cancer antimigration properties of fucoidans were also investigated using 2D wound healing and 3D spheroid-based assays. Furthermore, the long-term survival of HCT116 cells was investigated through the clonogenic assay after treatment with fucoidans. Lastly, glucose uptake and lactate export assays revealed the influence of fucoidan on glucose uptake and the glycolytic flux of HCT116 cells. Fucoidans were successfully extracted with a yield between 2.2% and 14.2% on a dry weight basis. EDTA extracts produced the highest yields than the water and the acid extracts. Ecklonia spp. fucoidans displayed the highest total carbohydrate content, with glucose and galactose being the major monosaccharides. S. elegans and commercial Fucus vesiculosus had lower carbohydrate contents but contained more sulphates than the Ecklonia spp. fucoidans. Furthermore, the extracted fucoidan contained little to no contaminants, including proteins, phenolics and uronic acids. In addition, the extracted fucoidans were determined to be >100 kDa through ultracentrifugation. Mass spectrometry also detected the most abundant peak for all fucoidans to be around 700 Da (m/z). Extracted fucoidans inhibited the activity of α-glucosidase more strongly than the commercial anti-diabetic agent acarbose but were inactive on α-amylase. Fucoidans were also shown to be mixed inhibitors of α-glucosidase. Compellingly, fucoidans synergistically inhibited α-glucosidase in combination with the anti-diabetic agent acarbose, highlighting prospects for combination therapy. Finally, fucoidans demonstrated some anti-proliferative characteristics on HCT116 cancer cells by inhibiting their ability to adhere to the tissue culture plate matrix. Furthermore, some fucoidan extracts inhibited the migration of HCT116 cancer cells from 3D spheroids. Some of our fucoidan extracts also inhibited HCT116 colony formation, demonstrating inhibition of long-term cell survival. The E. maxima water extract also inhibited glucose uptake by HCT116 cells, thereby influencing the glycolytic flux. In conclusion, biologically active fucoidans were successfully extracted from South African brown seaweeds. These fucoidans demonstrated anti-diabetic and anti-cancer properties, revealing their relevance as potential drugs for these diseases. , Thesis (PhD) -- Faculty of Science, Biochemistry and Microbiology, 2022

- Description: This study makes a contribution to the field of sustainable agricultural development and women empowerment in rural South Africa by examining the transformations derived from an expansive learning process with a women farmers group in terms of their food production capability expansion and empowerment as well as the well-being of their local catchment or landscape where their activity was situated. The study took place in the Lutengele villages along the upper reaches of the lower Mzimvubu Catchment near Port St Johns in the Eastern Cape province of South Africa. Women in southern Africa are significant contributors to household livelihoods through their household food production practices and at the same time they are also one of the primary natural resource users in rural landscapes. In this case study, historical and contemporary ethnographic and situational data revealed disjuncture between existing practice and the fulfilment of women aspirations with regard to food security and social and ecological well-being at large. As a result, central to this study were the concepts of aspirations and capabilities and the role that these played in transformative learning processes via formative intervention research (after Engeström’s concept of expansive learning). Expansive learning emerges from Vygotsky’s early work on mediation of learning through language and culture, which gave raise to Cultural Historical Activity Theory (CHAT). Whereas the Capability Approach (CA) recognises that development interventions or initiatives should focus on “expanding the freedom that deprive people from enjoying their valued beings and doings” (Sen, 1999, p. 3), in other words, what people value or have reason to value. The Capability Approach coupled with CHAT deepens the contextual understanding of the agricultural activity system in light of the engendered power dynamics associated with women having access to productive resources, their culturally expected roles and responsibilities in the institution of their households, their families and the community at large, and most importantly, aspects of gerontocracy defined by their age and status in society. In addition, drawing on the Capability Approach as a lens to view agricultural development, social transformation and empowerment, provided the tools to conceptualise participants’ aspirations, their true value and the capabilities necessary for such aspirations to be realised in a context filled with socio-cultural and political power relations and dynamics faced especially by women. The first phase of the study set out to map the context in which the participants’ small-scale food production activity was situated, their aspirations relevant to sustainable agricultural livelihoods, food security, well-being and lastly, the main factors or contradictions inhibiting participants from attaining the aspired food production goals. During the initial phase of the expansive learning cycle I was able to address the first research question: What tensions and contradictions in aspiration-practice relationships shape household food security in the context of catchment management of the women farmers’ group or river forum in the Lutengele area? Twelve contradictions were identified from the historical and contemporary socio-cultural analysis of the home-based food production practices and agricultural activity in relation to the research participants’ envisaged aspirations, which under further scrutiny were thereafter considered by the participants as critical capabilities to pursue during the collective and transformative learning process in the second phase of the study. In the second phase of the study, a series of second stimuli were introduced in the form of conceptual and material tools and tasks with the aim to move participants along the expansive learning process. This led to the unfolding of the collectively defined Capability Learning Pathways for sustainable food production or expansion of their agricultural capability in the context of sustainability of the local micro-catchment or landscape. Through the various Change Laboratory workshops and supporting mini-cycles in the last stages of the formative interventionist research, participants’ learning and development was supported in a way that not only brought individuals together to co-design relevant solutions, strategies and working groups or committees, but also catalysed and amplified transformative agency and the expansion of food production capability, sustainable land use practices and ultimately empowerment. This answered the second and most important research question: Can, and if so, how can expansive social learning processes shape conversion factors for turning available resources into functionings that enhance household food security capabilities and ecological well-being? The methodology of expansive learning and formative interventionist research design intervention, with supporting mediating tools, has proven a positive intervention in the attainment of capabilities (or functionings) in relation to the participant’s aspired livelihoods and consequently improving their well-being as well as their ability to navigate through the various gendered power dynamics, especially for the young women participating in this study. The study proposes expansive learning as a suitable critical and transformative learning theory and methodology for the mediation of collective deliberations and the pursuit of capability development as charted by the learners’ collective and individual aspirations. This is a learning process that not only pursues the learners’ attainment of material and cognitive changes but also opens up new opportunities and most importantly, the freedom to exercise their agency no matter the circumstances they find themselves in – in other words, the freedom to aspire and to be, do and become what one values as instrumentally and intrinsically critical to live a life that they have reason to value. In sum, the unfolding of the expansive learning process happened at three levels: at the value clarification level in terms of human and non-human relationships and social relationality, the institutional level and the practices level. The study recommends further research on the suitability of expansive learning and Change Laboratories as a Capability Expansion Methodology involving human development and Capability Approach practitioners, particularly those with an interest in informal learning and community-based empowering initiatives. Additionally, further studies are also suggested for examining formative interventionist research as a participatory action research approach for capability development work in education and learning research and in different study fields and contexts. , Thesis (PhD) -- Faculty of Education, Education, 2022

- Description: This study makes a contribution to the field of sustainable agricultural development and women empowerment in rural South Africa by examining the transformations derived from an expansive learning process with a women farmers group in terms of their food production capability expansion and empowerment as well as the well-being of their local catchment or landscape where their activity was situated. The study took place in the Lutengele villages along the upper reaches of the lower Mzimvubu Catchment near Port St Johns in the Eastern Cape province of South Africa. Women in southern Africa are significant contributors to household livelihoods through their household food production practices and at the same time they are also one of the primary natural resource users in rural landscapes. In this case study, historical and contemporary ethnographic and situational data revealed disjuncture between existing practice and the fulfilment of women aspirations with regard to food security and social and ecological well-being at large. As a result, central to this study were the concepts of aspirations and capabilities and the role that these played in transformative learning processes via formative intervention research (after Engeström’s concept of expansive learning). Expansive learning emerges from Vygotsky’s early work on mediation of learning through language and culture, which gave raise to Cultural Historical Activity Theory (CHAT). Whereas the Capability Approach (CA) recognises that development interventions or initiatives should focus on “expanding the freedom that deprive people from enjoying their valued beings and doings” (Sen, 1999, p. 3), in other words, what people value or have reason to value. The Capability Approach coupled with CHAT deepens the contextual understanding of the agricultural activity system in light of the engendered power dynamics associated with women having access to productive resources, their culturally expected roles and responsibilities in the institution of their households, their families and the community at large, and most importantly, aspects of gerontocracy defined by their age and status in society. In addition, drawing on the Capability Approach as a lens to view agricultural development, social transformation and empowerment, provided the tools to conceptualise participants’ aspirations, their true value and the capabilities necessary for such aspirations to be realised in a context filled with socio-cultural and political power relations and dynamics faced especially by women. The first phase of the study set out to map the context in which the participants’ small-scale food production activity was situated, their aspirations relevant to sustainable agricultural livelihoods, food security, well-being and lastly, the main factors or contradictions inhibiting participants from attaining the aspired food production goals. During the initial phase of the expansive learning cycle I was able to address the first research question: What tensions and contradictions in aspiration-practice relationships shape household food security in the context of catchment management of the women farmers’ group or river forum in the Lutengele area? Twelve contradictions were identified from the historical and contemporary socio-cultural analysis of the home-based food production practices and agricultural activity in relation to the research participants’ envisaged aspirations, which under further scrutiny were thereafter considered by the participants as critical capabilities to pursue during the collective and transformative learning process in the second phase of the study. In the second phase of the study, a series of second stimuli were introduced in the form of conceptual and material tools and tasks with the aim to move participants along the expansive learning process. This led to the unfolding of the collectively defined Capability Learning Pathways for sustainable food production or expansion of their agricultural capability in the context of sustainability of the local micro-catchment or landscape. Through the various Change Laboratory workshops and supporting mini-cycles in the last stages of the formative interventionist research, participants’ learning and development was supported in a way that not only brought individuals together to co-design relevant solutions, strategies and working groups or committees, but also catalysed and amplified transformative agency and the expansion of food production capability, sustainable land use practices and ultimately empowerment. This answered the second and most important research question: Can, and if so, how can expansive social learning processes shape conversion factors for turning available resources into functionings that enhance household food security capabilities and ecological well-being? The methodology of expansive learning and formative interventionist research design intervention, with supporting mediating tools, has proven a positive intervention in the attainment of capabilities (or functionings) in relation to the participant’s aspired livelihoods and consequently improving their well-being as well as their ability to navigate through the various gendered power dynamics, especially for the young women participating in this study. The study proposes expansive learning as a suitable critical and transformative learning theory and methodology for the mediation of collective deliberations and the pursuit of capability development as charted by the learners’ collective and individual aspirations. This is a learning process that not only pursues the learners’ attainment of material and cognitive changes but also opens up new opportunities and most importantly, the freedom to exercise their agency no matter the circumstances they find themselves in – in other words, the freedom to aspire and to be, do and become what one values as instrumentally and intrinsically critical to live a life that they have reason to value. In sum, the unfolding of the expansive learning process happened at three levels: at the value clarification level in terms of human and non-human relationships and social relationality, the institutional level and the practices level. The study recommends further research on the suitability of expansive learning and Change Laboratories as a Capability Expansion Methodology involving human development and Capability Approach practitioners, particularly those with an interest in informal learning and community-based empowering initiatives. Additionally, further studies are also suggested for examining formative interventionist research as a participatory action research approach for capability development work in education and learning research and in different study fields and contexts. , Thesis (PhD) -- Faculty of Education, Education, 2022

- Description: Land degradation is a global phenomenon which is having serious negative consequences for rural livelihoods, which depend quite fundamentally on land and its resources. At the same time, one of the key conditions contributing to land degradation relates to rural livelihood practices, insofar as these practices fail to protect the land. Hence, there sometimes exists a mutually-reinforcing process of decline, in relation to both land vitality and livelihoods vitality over time. This thesis seeks to investigate and understand this complex land-livelihoods process through a case study of two fast track farms in the Shurugwi District of contemporary Zimbabwe. In the year 2000, the Zimbabwean government introduced the fast track land reform programme which fundamentally reconfigured the rural landscape. In particular, it led to the formation of A1 farms (containing small-scale farming units called A1 plots), onto which people were resettled for purposes of enhancing their livelihoods. The case study focuses on two A1 farms in the district, namely, Selukwe Peak and Adare farms. Through a longitudinal study of land and livelihoods on these A1 farms, this study seeks to identify the multi-faceted character of land degradation on the farms, the multi-layered conditions (or causes) facilitating land degradation (specifically, the farm-based livelihood practices) and the effects of this land degradation on these very livelihood practices. This includes a focus on farmers’ understandings of land degradation and how these understandings may or may not condition livelihood practices on the two farms. Of particular importance is the presence of not only agricultural practices, but also high levels of illegal and legal mining on the farms and in the surrounding areas. In pursuing this study, the thesis draws upon the Sustainable Livelihoods Approach alongside Margaret Archer’s morphogenetic sociological perspective. Combined, they provide an intricate understanding of the relevance of both structure and agency to the analysis. A qualitative methodology was used, and this involved a questionnaire survey, in- depth interviews, life histories, focus group discussions and transect walks. The study concludes that the livelihood strategies undertaken by the villagers of Selukwe Peak and Adare farms are key causes of land degradation, as are the land-degrading activities of illegal and legal miners. The A1 villagers are aware that their activities are causing land degradation but they continue these activities because they are pushed by circumstances beyond their control. Hence, both proximate and underlying causes are of some significance in understanding land degradation and livelihoods on the two farms, and their interrelationships. , Thesis (PhD) -- Faculty of Humanities, Sociology, 2022

- Description: Postal organisations play an important role in the provision of basic communication services. In Zimbabwe, post offices have a large physical distribution network of over 240 post offices country-wide to make communication services accessible to the populace. However, e-substitution has threatened mail business significantly. Postal operators globally are experiencing declining mail volumes in the face of advanced information and communication technologies. The overall goal of this thesis was to undertake a socio-historical analysis of organisational change at ZimPost using Taylorism, Fordism and post-Fordism as broad ideal types to explain how industry evolves in different phases of capitalism. National politics and economics play an integral role in how Taylorism, Fordism and post-Fordism assumed at ZimPost. Studies on these broad organising types have mainly focused on private sector organisations. However, this thesis argues that these analytical paradigms are also valid in public sector organisations, but they will unfold differently given the context in which change is experienced. Using a qualitative approach, the study established that the 1980s and 1990s can best be described as the ‘golden years’ of postal services in Zimbabwe, characterised by mass production and mass consumption of postal products and services. At that time the Posts and Telecommunications Corporation enjoyed a monopoly of postal services in the country. The stable market share, competitive salaries for postal workers, increased unionisation and a fairly stable economy enabled a Fordist regime of accumulation to develop. The cycle broke down when the mode of regulation was weakened by national economic and political changes towards the late 1990s. PTC started to experience a decline in the consumption of postal products. The decline was also attributed to increased competition from smaller private courier operators that could provide specialised services to a market with changing needs. With increased competition, the advancement of information, and communication technologies, mail volumes dwindled. This period can best be described as the crisis of Fordism at ZimPost. In the year 2000, the government unbundled the posts and telecommunications corporation to create four companies including Zimbabwe Posts. This was perceived as one of the most radical organisational changes in the history of postal services in Zimbabwe. More organisational changes took place at ZimPost that can best be described as characteristics of post-Fordism. These changes were attempts by ZimPost to remain relevant in light of the economic, political and technological changes taking place in the country. The postal operator introduced customised products in the form of agency services, supported by increased use of information and communication technologies in the post office. Organisational changes at ZimPost were shaped mainly by the economic and political environment in which they took place. Organisational change is complex, changes do not follow a linear pattern, they are processual. , Thesis (PhD) -- Faculty of Humanities, Sociology, 2022

- Description: The field of supramolecular chemistry has grown large and wide in both deepness of understanding, range of topics covered and scope and applications. Supramolecular self-assemblies are facilitated by a wide range of non-covalent intra and inter molecular interactions that range from hydrogen bonding to π-interaction and van der Waals. Macrocyclic compounds such as cucurbiturils and calixarenes have emerged as important classes of compounds with excellent potential of forming supramolecular assemblies. The porous nature of these compounds enables them to form host-guest supramolecular complexes stabilized by diverse range of non-covalent interactions. Furthermore, these compounds contain donor atoms capable of forming bonds with metal ions to yield metal complexes with interesting porous characteristics that deviate from their traditional hydrophobic cavity. The versatile nature of the resulting pores imply that they can accommodate diverse types of guests. This work explores the synthesis and characterization of a host of calixarenes and cucurbiturils. Self-assembly of these macrocycles with various metal ions results to the formation of porous metal organic framework (MOF) complexes. Four new calixarene typed compounds obtained from aromatic aldehydes and twenty-six cucurbituril metal complexes are reported. These macrocylces and their metal complexes also form supramolecular complexes with DMSO, methanol, isoniazid hydrochloride and ciprofloxacin hydrochlorides through either self-assembly, mechanochemistry and exposure to solvent vapors. The bulk materials have been characterized using nuclear magnetic resonance spectroscopy (NMR), Fourier transformed infrared spectroscopy (FTIR), powder and single crystal diffraction techniques and thermal studies thermogravimetric analysis (TGA) and differential thermal calorimetry (DSC). Data obtained from this study reveals that calixarenes can form supramolecular complexes with a frequently used laboratory solvents with BN22 showing appreciable selectivity for DMSO sorption from a solvent mixture. These compounds also form supramolecular complexes with drug molecules such as isoniazid and ciprofloxacin. Furthermore, the data reveals that choice of synthetic route of supramolecular ensembles dictates if the guest drug molecule will occupy the intrinsic or extrinsic pores of cucurbituril complexes. Biological studies on the obtained complexes reveal that the cucurbituril complexes are non-cytotoxic while the calixarenes show antibacterial activity against Escherichia coli and Staphylococcus aureus. Additionally, the study showed that ciprofloxacin can be successfully released from a calixarene host in a simulated body fluid although the host was also found to cross the dialysis membrane. The results of this study are important in that; - they can be exploited and developed in the selective sorption of certain guests and - that they can be used in the development of drug delivery systems that play a dual role of delivery and therapeutic activity. , Thesis (PhD) -- Faculty of Science, Chemistry, 2022

- Description: Community engagement (CE) is now widely considered a core function of higher education worldwide. In South African higher education institutions (HEIs), there is an increasing focus on CE as a means of transforming the role of the university in society, though the forms and shapes of CE vary by institution. CE is positioned as part of the means of addressing the challenges within the South African education system, such as ensuring equity in academic access in the face of diversity and making sure higher education institutions are responsive to the needs of society. Community Engagement is increasingly being afforded the same status as teaching and learning and research in higher education. The idea that higher education should function as a public good is central to this. This study reflects on how CE can be expansively viewed as places of learning for students to achieve epistemic access with epistemic justice, particularly in increasing diverse and changing contexts. Despite the growing research on CE in HEIs, there is comparatively limited focus on the intersection between CE and language use and potential linkages with identity and epistemic access and success. Given that one of the major challenges in South African HEIs relate to difficulties experienced by students whose home language is not English, the experiences of students learning within CE contexts within those institutions warrants investigation. The main aim of this study was to explore second language English speaking students’ experiences of language in the Engaged Citizen Programme, a Community Engagement programme at Rhodes University aimed at offering students the opportunity of enhanced learning, giving students the opportunity to evaluate the theories and ideas taught in the university against the realities of the South African context. The programme is also intended to offer students the opportunity to learn with and from communities and thereby enable personal growth (ECP Handbook: 2020; p.3). Using an in-depth phenomenological approach, this study explored diverse students’ experiences of language use in both community engaged programmes and in the classroom as a basis for understanding the role language plays in such spaces and the impact of these programmes on epistemic access, justice and success for students in HEIs. The study explored the role that CE plays for second language English students as they navigate complex questions of identity and belonging in HEIs. In CE activities, such as the Engaged Citizen Programme, unlike traditional classroom learning, English is often not the medium of instruction, as learning takes place in community sites, where multiple other languages are spoken. In the traditional classrooms, English is the dominant medium of instruction which can bring challenges for students whose home language is not English. Students are faced with various challenges including failure to communicate effectively and understand content knowledge. Significantly this study found that this often related to a sense of self-worth and belonging and constrained their participation and engagement in class. It was evident from the students’ reflections on their experiences in the Engaged Citizen Programme that CE provided a more flexible space generally more comfortable to these participants; a space that promotes engaged learning without rigid rules. The students’ reflections affirmed the contribution of CE in promoting engagement of students outside the formal classes and enhancing the ways in which they use language freely. It was also evident from the students’ reflections that CE provided a space in which students can identify who they are and have a sense of belonging. In the context of diversity, the majority of the students said they come to the university feeling a level of under preparedness and cannot identity with dominant groups. The reflections from the students’ experiences therefore offer some insights into ways in which we can actively promote CE in supporting student access and addressing issues of epistemic justice in higher education. The findings suggest that many of the benefits of CE, such as higher levels of interaction and significant amounts of translanguaging, need to be brought into the formal classroom spaces because they enhanced student engagement. While CE was also seen to be challenging and there were calls for more support, the essence of the experience was as a space of personal development and awareness of social responsibility. The explicit normative value of CE was in contrast to the absence of such considerations in the formal HE curriculum and the student experiences suggest that much could be learned from this. The use of English, both on campus and in CE activities, was found to be value-laden and politically charged. The participants, black students who spoke English as an additional language, all related experiences of English being positioned as a ‘superior’ language. The students who were highly fluent in English experienced being positioned as ‘showing off’ and seen to have ‘forgotten their roots’. Students who were not highly fluent in English, on the other hand, often constrained their participation in class because they experienced concern that their mispronunciations and accents may be mocked. The essence of the experience of language use in both formal classroom settings and in CE activities is that this is tightly bound to identity and is ideologically fraught. This requires more explicit conversation in all learning spaces. , Kubatirana pamwe nenharaunda (KPN) (CE) iko zvino kwave kutariswa zvakanyanya sembiru yebasa redzidzo yepamusoro pasirese.

- Description: Community engagement (CE) is now widely considered a core function of higher education worldwide. In South African higher education institutions (HEIs), there is an increasing focus on CE as a means of transforming the role of the university in society, though the forms and shapes of CE vary by institution. CE is positioned as part of the means of addressing the challenges within the South African education system, such as ensuring equity in academic access in the face of diversity and making sure higher education institutions are responsive to the needs of society. Community Engagement is increasingly being afforded the same status as teaching and learning and research in higher education. The idea that higher education should function as a public good is central to this. This study reflects on how CE can be expansively viewed as places of learning for students to achieve epistemic access with epistemic justice, particularly in increasing diverse and changing contexts. Despite the growing research on CE in HEIs, there is comparatively limited focus on the intersection between CE and language use and potential linkages with identity and epistemic access and success. Given that one of the major challenges in South African HEIs relate to difficulties experienced by students whose home language is not English, the experiences of students learning within CE contexts within those institutions warrants investigation. The main aim of this study was to explore second language English speaking students’ experiences of language in the Engaged Citizen Programme, a Community Engagement programme at Rhodes University aimed at offering students the opportunity of enhanced learning, giving students the opportunity to evaluate the theories and ideas taught in the university against the realities of the South African context. The programme is also intended to offer students the opportunity to learn with and from communities and thereby enable personal growth (ECP Handbook: 2020; p.3). Using an in-depth phenomenological approach, this study explored diverse students’ experiences of language use in both community engaged programmes and in the classroom as a basis for understanding the role language plays in such spaces and the impact of these programmes on epistemic access, justice and success for students in HEIs. The study explored the role that CE plays for second language English students as they navigate complex questions of identity and belonging in HEIs. In CE activities, such as the Engaged Citizen Programme, unlike traditional classroom learning, English is often not the medium of instruction, as learning takes place in community sites, where multiple other languages are spoken. In the traditional classrooms, English is the dominant medium of instruction which can bring challenges for students whose home language is not English. Students are faced with various challenges including failure to communicate effectively and understand content knowledge. Significantly this study found that this often related to a sense of self-worth and belonging and constrained their participation and engagement in class. It was evident from the students’ reflections on their experiences in the Engaged Citizen Programme that CE provided a more flexible space generally more comfortable to these participants; a space that promotes engaged learning without rigid rules. The students’ reflections affirmed the contribution of CE in promoting engagement of students outside the formal classes and enhancing the ways in which they use language freely. It was also evident from the students’ reflections that CE provided a space in which students can identify who they are and have a sense of belonging. In the context of diversity, the majority of the students said they come to the university feeling a level of under preparedness and cannot identity with dominant groups. The reflections from the students’ experiences therefore offer some insights into ways in which we can actively promote CE in supporting student access and addressing issues of epistemic justice in higher education. The findings suggest that many of the benefits of CE, such as higher levels of interaction and significant amounts of translanguaging, need to be brought into the formal classroom spaces because they enhanced student engagement.

- Description: The study explores the enablements and constraints in the uptake of educational technologies in the South African higher education system. This is a multiple institutional study which considers the differentiated nature of higher education institutions in South Africa and reflects on the implications of this for the use of educational technology (EdTech). EdTech is seen as an important aspect of 21st century education. As an established practice in many universities it has made a significant impact on teaching and learning practices. However, EdTech is often presented as a panacea to educational problems and implemented without consideration of the contexts in which it is used. Data was collected from the educational technology units of 22 of the 26 public higher education institutions and the main sources of this data were an online survey questionnaire related to the uptake of educational technologies and semi-structured interviews. For the research analysis, Archer’s analytical dualism and morphogenetic cycle provided a framework with the understanding that a social phenomenon such as EdTech emerges from a complex interplay of multiple mechanisms rather than through simple unidirectional causality. The framework directed me to analyse structure, culture and agency as separate entities allowing an understanding of the complex and rapidly growing phenomenon of EdTech. Analytical dualism provides guiding principles on how agential actions, structural resources, and cultural practices emerge and allows an understanding of how agents experience and respond to structures and cultures in social fields, for example, the uptake of EdTech for teaching and learning. The morphogenetic cycle reveals the historical nature the EdTech uptake with events happening over a period of time so that past events, which possess structural and cultural mechanisms, condition agency in socio-cultural interaction. The study identified several mechanisms enabling and constraining the uptake of EdTech, and while the findings are not exhaustive, they do indicate important enablements and constraints which the sector would do well to consider as it enters a post-pandemic phase. The data was collected prior to the pandemic and thus provides an understanding of what allowed for the uptake of EdTech when face-to-face teaching and learning was the norm. While the pandemic resulted in a rapid pivot to Emergency Remote Teaching (ERT), and fundamentally changed the face of EdTech in the South African higher education sector and around the world, the findings of this study remain pertinent. Archer argues that when a new person or structure is introduced, it occurs within a pre-existing context and so what emerges should not be seen to be simply caused by that new person or structure. Rather, its emergent properties are exercised within the conditioning effects of the pre-existing structures, cultures and agents. The Covid-19 virus brought about significant effects around the world, but it would be a mistake for us to assume that the effects were the same across different national higher education systems or even across different universities within a country. For us to understand both what occurred during the pivot to ERT and to consider the implications of this for the future of EdTech, it is imperative that we understand the pre-existing conditions in which ERT was implemented. This thesis offers a rich picture of these pre-existing conditions. Key findings include the extreme extent to which universities differed in their resourcing and uptake of EdTech prior to the pandemic. In some universities, there were well-resourced EdTech centres while in others, the implementation of EdTech was seen to be the responsibility of the IT department. Even where EdTech staff were employed, the nature of this employment varied greatly. In some cases, such staff were seen as educational experts who were hired as academics and often worked within academic development centres. In other cases, such staff were employed as administrative support staff. Another difference pertained to whether they were employed on contract (often funded through project funding) or on a permanent basis. These differences in employment and the positioning of the EdTech staff were seen to greatly condition the levels of credibility they enjoyed and the kinds of work they could undertake. If they were employed as support staff, they were more likely to be seen to be responsible for providing academics with end-user technical assistance. If they were employed as academics, they were more likely to be seen to be responsible for providing pedagogical and curriculum development support in using EdTech for teaching and learning. Another set of findings related to the extent to which EdTech was seen to be valued within each university, such as by being included in promotions criteria, mentioned in institutional strategies, and supported by university management. Where this was not the case, this constrained the uptake of EdTech. In all cases, the EdTech staff reported working almost exclusively with academics who sought to develop their EdTech capability on a voluntary basis because it aligned to what Archer terms their ‘personal projects’. At times a departmental champion, especially in the form of the Head of Department as a social actor, led to EdTech uptake spreading across the academic body. There was evidence of some resistance to the use of EdTech and a great deal of anxiety among some academics. This was seen to be implicated in concerns that at times EdTech was seen to be a ‘dumping ground’ and the Learning Management System positioned simply as a repository of materials. Many academics reported being pushed by their students to integrate more technology in their teaching. Many students seem to be adept at using technology and can see its potential pedagogical benefits and so placed pressure for this to be increased. There were however concerns that the notion of ‘Digital Natives’, that is millennial students who were born into a technological era, was only a partial picture of the student body. The ‘Digital Divide’ meant that there was highly uneven access to hardware, data, bandwidth, and technological literacies among the student body. For many students, their only access to technology was while they were physically on campus, a finding that was to have extreme implications for the pivot to ERT. This research will be valuable to the field of educational technology and enhance the understanding of what is needed to enable the uptake of educational technologies in higher education teaching and learning in pedagogically sound ways. As the sector responds to the pandemic and reflects on lessons learned during this time, it will be important to look to the conditions outlined in this study as they continue to enable and constrain the uptake of educational technology. , Ucwaningo olwethulwe yindlela elandela imigomo ka-Bhaskar kanye no-Archer yesayensi yezenhlalo ehlola ukuze inikeze incazelo yokuvumeleka nezithiyo ekuthathweni kwezifundo ezisekwe ubuchwepheshe besimanje. Lolu ucwaningo lwezikhungo eziningi zemfundo ephakeme, futhi inhloso yalo enkulu bekuwukuhlonza ukuthi kwavela kanjani izindlela ezehlukene ukuze kuvunyelwe futhi kuvinjwe ukusetshenziswa kobuchwepheshe bezemfundo ezikhungweni zemfundo ephakeme ezehlukene eNingizimu Afrika. Izifundo ezisekwe ubuchwepheshe besimanje (EdTechs) ibonwa njengezici ezibalulekile zemfundo yekhulu lamashumi amabili nanye (21st century), futhi njengomkhuba osunguliwe emanyuvesi ibe nomthelela omkhulu ekufundiseni nasekufundeni. Kodwa-ke, i-EdTechs ivame ukwethulwa njengekhambi ezinkingeni zemfundo futhi yacwaningwa ngaphandle kokucabangela izimo lapho isetshenziswa khona. Ngenxa yalokho, kwaba nesidingo sokuqonda kangcono ukuthi ukutholwa kwayo kwehlukaniswa kanjani phakathi nohlelo lwemfundo ephakeme olungalingani emaNyuvesi ahlukene. Ubufakazi buqoqwe ezingxenyeni zobuchwepheshe bezemfundo zezikhungo zemfundo ephakeme zikahulumeni ezingamashumi amabili nambili (22) kwezingamashumi amabili nesithupha (26) futhi imithombo eyinhloko yalobufakazi kwakuwuhlu lwemibuzo lwenhlolovo oluku-inthanethi oluhlobene nokusetshenziswa kobuchwepheshe bezemfundo kwase kulandela kanye nezingxoxiswano ezihlelwe kancane. Ukuze kuhlaziywe ucwaningo, i-analytical dualism ngokuka-Archer kanye nomjikelezo we-morphogenetic (uzalo kabusha) unikeze uhlaka lokuhlaziywa kokutholwa kobuchwepheshe bezemfundo njengokusebenzelana okuqhubekayo phakathi kwezifundiswa nabasebenzi bomnyango bobuchwepheshe besimanje (EdTech staff). Ekuhlaziyeni, ngixoxa ngokuthi uhlaka lungiqondise kanjani ukuba ngihlaziye isakhiwo, isiko kanye nokwenza kwabantu njengezinhlangano ezihlukene nokuthi kungani lolu hlaka lufaneleka ukuze siqonde lesi simo esiyinkimbinkimbi nesikhula ngokushesha sezemfundo zobuchwepheshe besimanje. Ubumbaxambili bokuhlaziya buhlinzeka ngohlaka oluvumela abacwaningi ezimweni zomphakathi ukuthi babone futhi bahlaziye izindlela ezikhiqizayo neziyisisekelo, okuhlanganisa izindlela zokwenza ngokusebenzisa ukuxhumana komphakathi. Iphinde inikeze izimiso eziqondisayo zokuthi ezinye izenzo zokwenza komuntu kanye nemikhuba yamasiko zivela kanjani kanye nokuqonda ukuthi abenzi nabasebenzi bezemfundo, nokuthi abhekana kanjani futhi asabela kanjani ezakhiweni namasiko emikhakheni yezenhlalo, isibonelo, ukutholwa kwe-EdTechs ekufundiseni nokufunda. Ngaphezu kwalokho, umjikelezo we-morphogenetic wembula ubunjalo bomlando ukuthathwa kwe-EdTechs nezenzakalo ezenzeka esikhathini esithile ukuze izehlakalo ezidlule ezinezindlela zesakhiwo nezamasiko zibekezelele izenzo zezifundiswa njenge-ejensi ezovela ekusebenzelaneni kwezenhlalo namasiko. Izakhiwo ezivelayo zesakhiwo, isiko kanye nezabenzi zibonwa njengezindlela ezibalulekile ezivumela futhi zibambe iqhaza ekuthathweni kobuchwepheshe bezemfundo ekufundiseni nokufunda yizifundiswa. Ngakho-ke, ucwaningo luveza ukuthi kungani ukuthathwa kunezindlela ezivumelayo neziphoqayo futhi ukuxhumana phakathi kwesakhiwo, isiko kanye nomenzi kudala ukucabangela kwesimo okungaba okuncomayo noma okuphikisanayo ngokwemvelo. Imvume yokulandelana kwesimo yencazelo yokuthi kungani kunokuhlangenwe nakho okuhlukile ekuthathweni kwalawa ma-EdTech avela ezikhungweni ezehlukene esimweni semfundo ephakeme yaseNingizimu Afrika. Lolu cwaningo luzobaluleka emkhakheni wezobuchwepheshe bezemfundo futhi luthuthukise ukuqonda kwalokho okudingekayo ukuze kusetshenziswe ubuchwepheshe bezemfundo ekufundiseni nasekufundeni imfundo ephakeme. , Thesis (PhD) -- Faculty of Education, Centre for Higher Education Research, Teaching and Learning, 2022

EdTech is seen as an important aspect of 21st century education. As an established practice in many universities it has made a significant impact on teaching and learning practices. However, EdTech is often presented as a panacea to educational problems and implemented without consideration of the contexts in which it is used. Data was collected from the educational technology units of 22 of the 26 public higher education institutions and the main sources of this data were an online survey questionnaire related to the uptake of educational technologies and semi-structured interviews. For the research analysis, Archer’s analytical dualism and morphogenetic cycle provided a framework with the understanding that a social phenomenon such as EdTech emerges from a complex interplay of multiple mechanisms rather than through simple unidirectional causality. The framework directed me to analyse structure, culture and agency as separate entities allowing an understanding of the complex and rapidly growing phenomenon of EdTech. Analytical dualism provides guiding principles on how agential actions, structural resources, and cultural practices emerge and allows an understanding of how agents experience and respond to structures and cultures in social fields, for example, the uptake of EdTech for teaching and learning. The morphogenetic cycle reveals the historical nature the EdTech uptake with events happening over a period of time so that past events, which possess structural and cultural mechanisms, condition agency in socio-cultural interaction. The study identified several mechanisms enabling and constraining the uptake of EdTech, and while the findings are not exhaustive, they do indicate important enablements and constraints which the sector would do well to consider as it enters a post-pandemic phase. The data was collected prior to the pandemic and thus provides an understanding of what allowed for the uptake of EdTech when face-to-face teaching and learning was the norm. While the pandemic resulted in a rapid pivot to Emergency Remote Teaching (ERT), and fundamentally changed the face of EdTech in the South African higher education sector and around the world, the findings of this study remain pertinent. Archer argues that when a new person or structure is introduced, it occurs within a pre-existing context and so what emerges should not be seen to be simply caused by that new person or structure. Rather, its emergent properties are exercised within the conditioning effects of the pre-existing structures, cultures and agents. The Covid-19 virus brought about significant effects around the world, but it would be a mistake for us to assume that the effects were the same across different national higher education systems or even across different universities within a country. For us to understand both what occurred during the pivot to ERT and to consider the implications of this for the future of EdTech, it is imperative that we understand the pre-existing conditions in which ERT was implemented. This thesis offers a rich picture of these pre-existing conditions. Key findings include the extreme extent to which universities differed in their resourcing and uptake of EdTech prior to the pandemic. In some universities, there were well-resourced EdTech centres while in others, the implementation of EdTech was seen to be the responsibility of the IT department. Even where EdTech staff were employed, the nature of this employment varied greatly. In some cases, such staff were seen as educational experts who were hired as academics and often worked within academic development centres. In other cases, such staff were employed as administrative support staff. Another difference pertained to whether they were employed on contract (often funded through project funding) or on a permanent basis. These differences in employment and the positioning of the EdTech staff were seen to greatly condition the levels of credibility they enjoyed and the kinds of work they could undertake. If they were employed as support staff, they were more likely to be seen to be responsible for providing academics with end-user technical assistance. If they were employed as academics, they were more likely to be seen to be responsible for providing pedagogical and curriculum development support in using EdTech for teaching and learning. Another set of findings related to the extent to which EdTech was seen to be valued within each university, such as by being included in promotions criteria, mentioned in institutional strategies, and supported by university management. Where this was not the case, this constrained the uptake of EdTech. In all cases, the EdTech staff reported working almost exclusively with academics who sought to develop their EdTech capability on a voluntary basis because it aligned to what Archer terms their ‘personal projects’. At times a departmental champion, especially in the form of the Head of Department as a social actor, led to EdTech uptake spreading across the academic body. There was evidence of some resistance to the use of EdTech and a great deal of anxiety among some academics. This was seen to be implicated in concerns that at times EdTech was seen to be a ‘dumping ground’ and the Learning Management System positioned simply as a repository of materials. Many academics reported being pushed by their students to integrate more technology in their teaching. Many students seem to be adept at using technology and can see its potential pedagogical benefits and so placed pressure for this to be increased. There were however concerns that the notion of ‘Digital Natives’, that is millennial students who were born into a technological era, was only a partial picture of the student body. The ‘Digital Divide’ meant that there was highly uneven access to hardware, data, bandwidth, and technological literacies among the student body. For many students, their only access to technology was while they were physically on campus, a finding that was to have extreme implications for the pivot to ERT. This research will be valuable to the field of educational technology and enhance the understanding of what is needed to enable the uptake of educational technologies in higher education teaching and learning in pedagogically sound ways. As the sector responds to the pandemic and reflects on lessons learned during this time, it will be important to look to the conditions outlined in this study as they continue to enable and constrain the uptake of educational technology. , Ucwaningo olwethulwe yindlela elandela imigomo ka-Bhaskar kanye no-Archer yesayensi yezenhlalo ehlola ukuze inikeze incazelo yokuvumeleka nezithiyo ekuthathweni kwezifundo ezisekwe ubuchwepheshe besimanje. Lolu ucwaningo lwezikhungo eziningi zemfundo ephakeme, futhi inhloso yalo enkulu bekuwukuhlonza ukuthi kwavela kanjani izindlela ezehlukene ukuze kuvunyelwe futhi kuvinjwe ukusetshenziswa kobuchwepheshe bezemfundo ezikhungweni zemfundo ephakeme ezehlukene eNingizimu Afrika. Izifundo ezisekwe ubuchwepheshe besimanje (EdTechs) ibonwa njengezici ezibalulekile zemfundo yekhulu lamashumi amabili nanye (21st century), futhi njengomkhuba osunguliwe emanyuvesi ibe nomthelela omkhulu ekufundiseni nasekufundeni. Kodwa-ke, i-EdTechs ivame ukwethulwa njengekhambi ezinkingeni zemfundo futhi yacwaningwa ngaphandle kokucabangela izimo lapho isetshenziswa khona. Ngenxa yalokho, kwaba nesidingo sokuqonda kangcono ukuthi ukutholwa kwayo kwehlukaniswa kanjani phakathi nohlelo lwemfundo ephakeme olungalingani emaNyuvesi ahlukene. Ubufakazi buqoqwe ezingxenyeni zobuchwepheshe bezemfundo zezikhungo zemfundo ephakeme zikahulumeni ezingamashumi amabili nambili (22) kwezingamashumi amabili nesithupha (26) futhi imithombo eyinhloko yalobufakazi kwakuwuhlu lwemibuzo lwenhlolovo oluku-inthanethi oluhlobene nokusetshenziswa kobuchwepheshe bezemfundo kwase kulandela kanye nezingxoxiswano ezihlelwe kancane. Ukuze kuhlaziywe ucwaningo, i-analytical dualism ngokuka-Archer kanye nomjikelezo we-morphogenetic (uzalo kabusha) unikeze uhlaka lokuhlaziywa kokutholwa kobuchwepheshe bezemfundo njengokusebenzelana okuqhubekayo phakathi kwezifundiswa nabasebenzi bomnyango bobuchwepheshe besimanje (EdTech staff). Ekuhlaziyeni, ngixoxa ngokuthi uhlaka lungiqondise kanjani ukuba ngihlaziye isakhiwo, isiko kanye nokwenza kwabantu njengezinhlangano ezihlukene nokuthi kungani lolu hlaka lufaneleka ukuze siqonde lesi simo esiyinkimbinkimbi nesikhula ngokushesha sezemfundo zobuchwepheshe besimanje. Ubumbaxambili bokuhlaziya buhlinzeka ngohlaka oluvumela abacwaningi ezimweni zomphakathi ukuthi babone futhi bahlaziye izindlela ezikhiqizayo neziyisisekelo, okuhlanganisa izindlela zokwenza ngokusebenzisa ukuxhumana komphakathi. Iphinde inikeze izimiso eziqondisayo zokuthi ezinye izenzo zokwenza komuntu kanye nemikhuba yamasiko zivela kanjani kanye nokuqonda ukuthi abenzi nabasebenzi bezemfundo, nokuthi abhekana kanjani futhi asabela kanjani ezakhiweni namasiko emikhakheni yezenhlalo, isibonelo, ukutholwa kwe-EdTechs ekufundiseni nokufunda. Ngaphezu kwalokho, umjikelezo we-morphogenetic wembula ubunjalo bomlando ukuthathwa kwe-EdTechs nezenzakalo ezenzeka esikhathini esithile ukuze izehlakalo ezidlule ezinezindlela zesakhiwo nezamasiko zibekezelele izenzo zezifundiswa njenge-ejensi ezovela ekusebenzelaneni kwezenhlalo namasiko. Izakhiwo ezivelayo zesakhiwo, isiko kanye nezabenzi zibonwa njengezindlela ezibalulekile ezivumela futhi zibambe iqhaza ekuthathweni kobuchwepheshe bezemfundo ekufundiseni nokufunda yizifundiswa. Ngakho-ke, ucwaningo luveza ukuthi kungani ukuthathwa kunezindlela ezivumelayo neziphoqayo futhi ukuxhumana phakathi kwesakhiwo, isiko kanye nomenzi kudala ukucabangela kwesimo okungaba okuncomayo noma okuphikisanayo ngokwemvelo. Imvume yokulandelana kwesimo yencazelo yokuthi kungani kunokuhlangenwe nakho okuhlukile ekuthathweni kwalawa ma-EdTech avela ezikhungweni ezehlukene esimweni semfundo ephakeme yaseNingizimu Afrika. Lolu cwaningo luzobaluleka emkhakheni wezobuchwepheshe bezemfundo futhi luthuthukise ukuqonda kwalokho okudingekayo ukuze kusetshenziswe ubuchwepheshe bezemfundo ekufundiseni nasekufundeni imfundo ephakeme. , Thesis (PhD) -- Faculty of Education, Centre for Higher Education Research, Teaching and Learning, 2022

- Description: There are many examples of institutions which have made false claims, or performed certain acts, that have had, to varying degrees, a negative impact on their societies. For example, many corporations go to great lengths to present themselves as being environmentally friendly when in fact they are not. Many corporations have also been forced to recall dangerous products which they at one time or another insisted were safe. Research teams have misled participants with regard to what they can expect from their participation in studies, with grave consequences. Governments throughout the world are mired in corruption, and yet deny that this is so. One possible explanation is that in such situations these institutions are simply lying. However, another possible explanation is that these institutions are self-deceived, or lying to themselves. Recently it has been suggested that self-deception is something that affects certain groups as well as individuals. Given that institutions can wield a great deal of political, social and economic power, if institutions are capable of self-deception there is room for things to go awry on a very large scale with potentially dire consequences. Yet the explanations currently on offer for group-level self-deception appear to amount to instances of individual self-deception (either to certain key individual members of those groups being self-deceived, or to all or most members of a group sharing the same self-deceptive belief), and as such I do not regard the explanations currently on offer as satisfactory. I propose that there are certain situations in which we ought to see institutions themselves as self-deceived or lying to themselves. While the terms ‘self-deception’ and ‘lying to oneself’ are often used interchangeably, I differentiate between the two and argue that both institutional self-deception and an institution lying to itself are institution-level phenomena, and do not rely on any individual within the institution being self-deceived or lying to themselves. That this is so is of relevance to our attributions of accountability, and makes changes to institutional structure and procedures the focus of concern when it comes to preventing an institution succumbing to self-deception or lying to itself. , Thesis (PhD) -- Faculty of Humanities, Philosophy, 2022

- Description: In the Eastern Cape of South Africa, rural small-scale farmers live in uncertain times characterized by climate change and variability, which intensify social, political and financial inequalities. Therefore, there is a need to increase the understanding and interpretation of climate information to minimize crop production risk, reduce rural small-scale farmers’ vulnerability to climate, and maximize opportunities. Increasing the resilience among rural small-scale farmers requires appropriate and viable practical approaches. By using systems thinking approach (and the Raymond Mhlaba Municipality in the Eastern Cape as a study area), this research disseminates the complex nature of current climate information frameworks. Through inputs from farmers (through a Farmers Research Group methodology) and climate data, this thesis developed a new framework for communicating climate information (herein referred as the climate information communication systems framework) to rural small-scale farmers. The proposed climate information communication systems framework successfully integrates scientific and traditional knowledge. The framework constitutes certain stages, where the farming system and crop identification is the first stage. The second stage is the requirements stage, which has two relationships: scientist to crop requirements and farmers to crop requirements. At the scientist to crop requirements level, users will examine crop requirements by combining climatic data and crop simulations, while at the farmers to crop requirement, rural small-scale farmers use the scientific information to plan for the farming season. The farmer then decides the planting and growing period as well as the harvest timing. The study suggests that building links between rural small-scale farmers, extension officers, and scientists makes sharing information easier. The proposed climate information framework design illustrates that stakeholders now have a personal relationship with climate information transmission and can influence the different actions to reduce the effect of climate change unpredictability. The study established that climate change and variability influence recent agricultural output trends. Recent temperature and rainfall trends could have resulted in low crop productivity in the study area. The study also reflected that women are a critical resource in agriculture and rural economy and that middle-aged men and youth are less interested in farming. The findings also showed that women are more receptive to climate information; hence, to promote access and use of climate information remains vital to consider gender-specific aspects for appropriate decision-making in the agriculture sector. The study also recommends enhancing the Farmers Research Group technique. In the past, the scope of this methodology has been narrowly focused, and it must be explored to incorporate additional types of climate information and more debate about how climate is related to the decisions farmers for implementation or consideration. , Thesis (PhD) -- Faculty of Science and Agriculture, 2022

- Description: Early childhood development is fundamental to human development and success in later life. Several stakeholders influence that development. Developmental policies are advocating for formal education provision at that early childhood age. Therefore, relationships and interactions of these stakeholders are of paramount importance in ensuring effective early childhood education provisioning – especially between parents and practitioners. Yet it has been reported that sharing of information concerning children’s educational development is not happening between parents and ECD practitioners. ECD centres are said to face many problems such as poor teaching and learning which may result in weak childhood educational development. Some of these challenges can be addressed through enhancing the partnership between parents and the ECD practitioners. The purpose of this study was therefore to explore the parents and practitioners’ partnership in early childhood education provisioning in ECD centres in the East London district. This study used the mixed method approach in the sampling, data collection and data analysis processes. The study focused on the partnership between parents and ECD practitioners, on how they work together, their views, how they communicate, on decision making and the strategies to enhance the partnership of parents and practitioners. Research questions in this study required both qualitative and quantitative data and analysis techniques. Quantitative data was collected from the ECD practitioners and principals by using questionnaires and qualitative data was collected through interviews with the parents. Quantitative data was analysed using SPSS and qualitative data was analysed using the thematic approach. The findings indicated that both parents and practitioners are working together in supporting learning and development. Parents are said to provide resources for use at the centre. Parents and practitioners are using different modes of communication for the learning and development of the children, including technology-based WhatsApp and emails. Practitioners are said to include parents in some decision making. The results indicated that even though some parents are working together with practitioners, while other parents are still showing ignorance and lack of knowledge on how they can partner for the educational development of the children. , Thesis (PhD) -- Faculty of Education, 2022
