- Description: This thesis reports on the discursive construal of intersectional physical identities, with particular reference to ‘black’ female characters, in two novels: Sindiwe Magona’s Mother to Mother, and Edyth Bulbring’s The Mark. These novels are prescribed for Grade 10 English Home Language learners in all South African public schools. Gendered identity construction in texts has been widely discussed in critical linguistics, with some research showing that the ways in which bodies are construed reveal the hegemonic and stereotypical gendering of men and women. However, these arguments have not adequately addressed the intersectional nature of identity construction. This thesis employs Corpus-based Critical Discourse Analysis to investigate the complex physical identities of, especially, ‘black’ female characters in these two novels. The inclusion of Corpus Linguistics is essential for uncovering hidden patterns of language choice, while the analytical techniques and theoretical notions from Critical Discourse Analysis provide the explanatory power that underpins the qualitative analysis. The uses to which nine key body parts are put reveal discourse prosodies showing different intersectional realisations for intimacy, power, violence, emotion, and racial marking. These discourse prosodies are most starkly realised in the two body parts, one from each novel, that are statistically most clearly linked to ‘black’ female characters. HAIR in The Mark is used variously as a racial marker, a target for racism, and a symbol for racial pride. HEART in Mother to Mother is used almost exclusively to symbolise the emotional pain of a mother’s love, and how empathy for another mother’s pain can bridge racial divides. Principal findings reveal that both novels provide very necessary lessons in cross-racial empathy, pride in ‘blackness,’ and interracial relationships. However, it is of concern that these novels also exhibit an over-valorisation of motherhood, largely stereotypical depictions of gender roles, and ableist language. In sum, both novels promote some of the transformative principles of the national curriculum, and are shown to have a bearing on nation building.

“When the rainbow is enuf”: black postgraduate women’s experiences and perceptions of higher education and institutional culture – a case study of Rhodes University

- Description: This thesis sets out to investigate the perceptions which Black postgraduate students hold of the present-day toward Historically White Universities (hereafter referred to as HWUs) in South Africa as unique sites from which to investigate institutional culture and the legacy of educational marginalisation. Black women are of particular focus because of the interlocking nature of social inequalities that uniquely influence their comparable experience in the academy. Rhodes University, a top-ranked traditional university provides the institutional site for this investigation into HWUs. This thesis seeks to further explore the suggestion that desegregation of South Africa's institutions of higher learning have meant access, but not always acceptance. The paper explores what Black women students perceive to be Rhodes University's institutional culture and its impact on their lived realities. Subsequently, these women have learned who they are, and what place they occupy in South Africa today, through navigating a space not necessarily accommodating to Blackness and difference. There exists a plethora of literature on the issues which Black women scholars systematically encounter daily in the academy, in sub-Saharan Africa and beyond. Nonetheless, there needs to be a further inquiry on the question of belonging of Black womanhood in HWU post the student-led movements of the past few years that have renewed the challenge to South Africa's colonial past, its neoliberal present, and its scourge of gender-based violence. This paper captures an ongoing conversation around the role of Black women in addressing transformation in HWU. As a Black woman in an HWU, I found myself wondering whether there are certain experiences students like me have in common – realities with nuances we call to identify with to some extent. I collected data from six Black women with whom I conducted interviews, and used it to compile this report and its analysis. I believe that the social significance of this study speaks to the importance of hearing the stories of subaltern groups that are positioned in spaces of privilege, yet continue to be defined by the disadvantage of their gender, race, and various other factors.

- Description: Since the first human-to-human heart transplant in the world was performed by Prof Chris Barnard in Cape Town in 1967, heart transplantation has become the gold standard to treat people suffering from end stage heart failure. This thesis explores heart recipients’ perceptions and experiences of their chronic heart illness before and after transplantation. It examines the medical experience in terms of the clinical diagnosis, the standard of communication about the illness and the proposed treatment, and the post-transplant regime. It also reflects how recipients make sense of heart disease and learn to live with a transplanted heart. The thesis also shows the extent to which the recipients’ culture and individual identity impact such complex medical issues as end stage heart failure and transplantation. Qualitative research was undertaken in private sector heart transplant programmes in South Africa. The study is underpinned by Mishel’s (1990) uncertainty theory as well as by social constructionism.

- Description: This thesis utilises an interdisciplinary approach to understand the political significance of the experimental poetics used by Claudia Rankine in Citizen: An American Lyric and Koleka Putuma in Collective Amnesia. Rankine and Putuma offer contemporary reflections on what it means to occupy marginalised spaces in society. These artists experiment with formal and conventional aspects of literature to explore and create new definitions of what it means to be Black in society. Their works and techniques allow for thinking outside of dominant ideologies of race and posit alternative Black identities that are not found within canonical theory on Blackness. This project reflects on existing theories of Black subjectivity as evident in Frantz Fanon’s Black Skin, White Masks and Aimé Césaire’s Notebook on the Return to My Native Land. While these theorists did not reject the role of Black women in Western civilisation, they should be read as a moment in a series of counter-discourse to the Black Other rather than the finite canon of Black subjectivity. The emergence of Rankine and Putuma’s experimental poetics works to disrupt the conflation of the Black subject with the Black heteronormative male. Using Michelle M. Wright’s Physics of Blackness as its primary theoretical framework, this project advocates alternative and disruptive readings of Blackness that potentially shift Blackness away from its conflation with nationalism, masculinity and heteronormativity. This thesis uses a dialogical approach between political theory and literature which allows for Citizen and Collective Amnesia to be read as acts of resistance to epistemological erasure and as articulations of the politics relevant to the poets’ lived experiences. Both the United States and South Africa have a history of institutionalised racial segregation, which allows Rankine and Putuma to be read in relation to one another. Where the Civil Rights movement and the anti-apartheid struggle were both foregrounded as male-lead liberation movements contemporary social movements including #blacklivesmatter and #feesmustfall have initiated a return to the androcentric philosophies of Malcom X and Steve Biko, for example. As such Rankine and Putuma’s literature and art marks a reclamation of female empowerment and visibility in the face of a political rhetoric that continues to be masculine and nationalist in nature. In the absence of a space where Black female and queer bodies are adequately recognised, the poetry they write creates a space of self-representation and recognition.

- Description: The focus of this study centered on investigating the perceptions and opinions surrounding the eruption of strike action and its effectiveness during a collective bargaining process. The case study employed was the 2018 municipal strike in Port Elizabeth, organised by the South African Municipal Workers Union (SAMWU). A Marxist theoretical framework was chosen for this study. It argues that strike action is a means through which workers communicate their dissatisfaction or enforce particular demands, with trade unions playing a protagonist’s role. Strike action, generally, is caused by a plethora of reasons ranging from disciplinary issues and conditions and hours of work, to be mention a few. However, the major force behind strike eruption is the wage agenda, as workers are always striving to get better wages while employers, on the other hand, attempt to reduce them so as to increase profits. South Africa has had its fair share of municipal strike action ever since the apartheid period, the early stages of democracy up to the contemporary times of the 21st century with various strategies, successes and losses being experienced. Democracy in South Africa also saw some developments in the labour sphere in relation to statutes surrounding strike action. The LRA and the Constitution of South Africa inform the right to strike and offer guidelines as well as consequences that steer strike action in a direction that does not jeopardize the workers, employers and the general public. The research found that workers do understand what strike action is, its causes and its various implications. Furthermore, it was discovered that this worker tool has been successful in putting pressure on the negotiation process as well as luring employers back to the negotiation table, for example. However, it was also uncovered that there are present, factors that hampered the impact of strike action during the bargaining procedure in focus. These are namely, the political institutionalization of trade unions, ill-equipped union leaders, a reluctance to implement strike agreements by employers, the use of violence by municipal workers during the strike, to mention but a few. Therefore, when looking at the strike in question, the effectiveness of strike action during the collective bargaining process was found to be easily contestable.

For some clinicians it may spark a lifelong interest in clinical investigation, while for many others it may provide a potential publication opportunity. Integrating the specific requirements of an MMed mini-dissertation with those of standard medical publications can be difficult for first-time authors and their supervisors; published guidance caters to full-length laboratory Master’s or doctoral research. We suggest that research is more likely to be publishable if it is locally relevant, has a clear clinical message and is coherently presented.

- Description: The impact of formulation and process variables on the in-vitro release of prednisone from a multiple-unit pellet system was investigated. Box-Behnken Response Surface Methodology (RSM) was used to generate multivariate experiments. The extrusion-spheronization method was used to produce pellets and dissolution studies were performed using United States Pharmacopoeia (USP) Apparatus 2 as described in USP XXIV. Analysis of dissolution test samples was performed using a reversed-phase high-performance liquid chromatography (RP-HPLC) method. Four formulation and process variables viz., microcrystalline cellulose concentration, sodium starch glycolate concentration, spheronization time and extrusion speed were investigated and drug release, aspect ratio and yield were monitored for the trained artificial neural networks (ANN). To achieve accurate prediction, data generated from experimentation were used to train a multi-layer perceptron (MLP) using back propagation (BP) and the Broyden-Fletcher-Goldfarb-Shanno (BFGS) 57 training algorithm until a satisfactory value of root mean square error (RMSE) was observed. The study revealed that the in-vitro release profile of prednisone was significantly impacted by microcrystalline cellulose concentration and sodium starch glycolate concentration. Increasing microcrystalline cellulose concentration retarded dissolution rate whereas increasing sodium starch glycolate concentration improved dissolution rate. Spheronization time and extrusion speed had minimal impact on prednisone release but had a significant impact on extrudate and pellet quality. This work demonstrated that RSM can be successfully used concurrently with ANN for dosage form manufacture to permit the exploration of experimental regions that are omitted when using RSM alone.

- Description: Urban sustainability and justice depend upon the flow of water across complex urban space. Yet, the characteristics of urban space produce a fragmented sense of our water resources. Cape Town, South Africa, the context of this research, is one such city whose water challenges have been exacerbated by climate change-induced drought, to the extent that the city nearly shut off the water running to residents’ taps. This context presents a particular challenge for the focus of this special issue, transformative and transgressive learning, an emerging arena of thought and practice concerned with learning processes that might foster more sustainable socio-ecological relations. The empirical material for this research draws from 12 arts-based inquiry workshops run with youth in an environmental organisation over four months, exploring a local water crisis. The data were generated through an engaged arts-based research process. The paper traces how transformative and transgressive learning in the context of urban water crisis might be characterised as making (non)sense by bringing the empirical material into dialogue with five entry points of transformative and transgressive learning literature rooted in Freirean educational praxis. This paper crafts and engages the concept of making (non)sense, a way of thinking about qualities and processes of learning praxis that responds to the wicked sustainability challenges we face today, particularly in terms of a Global South perspective. I argue such a praxis needs qualities and processes that disrupt and trouble the norm in the context of the socio-ecological challenge of urban water.

- Description: The Water Research Commission (WRC) is well known for its high quality knowledge products. The Water Utilisation in Agriculture (WUA) section has, over the years, produced valuable knowledge to guide the harvesting and conservation of rainwater to improve agricultural productivity among smallholder crop farmers and household food producers. This knowledge is useful for especially the many women farmers around the country growing crops to feed their families, and whenever possible selling excess to generate some income. However, one of the problems experienced in the field is that this knowledge does not always reach the intended audience. This is the problem that the Amanzi [Water] for Food project was engaged with.

- Description: The Water Research Commission (WRC) is well known for its high quality knowledge products. The Water Utilisation in Agriculture (WUA) section has, over the years, produced valuable knowledge to guide the harvesting and conservation of rainwater to improve agricultural productivity among smallholder crop farmers and household food producers. This knowledge is useful for especially the many women farmers around the country growing crops to feed their families, and whenever possible selling excess to generate some income. However, one of the problems experienced in the field is that this knowledge does not always reach the intended audience. This is the problem that the Amanzi [Water] for Food project was engaged with.

- Description: This paper explores the emergence of transgressive learning in CHAT-informed development work research in a networked organic agriculture case study in Zimbabwe, based on intervention research involving district organic associations tackling interconnected issues of climate change, water, food security and solidarity. The study established that We change laboratories can be used to support transgressive learning through: confronting unproductive local norms; collective reframing of problematic issues; stimulating expansive learning and sustainability transformations in minds, relationships and landscapes across time. The study also confirms the need for fourth generation CHAT to address the complex social-ecological problems of today.

- Description: This paper explores the use of systems theory to inform the mainstreaming of sustainability in a university’s functions as it responds to sustainable development challenges in its local context. Offering a case study of Rhodes University, the paper shows how the use of systems models and concepts, underpinned by a critical realist ontology and an understanding of morphogenetic change processes, have the potential to enable universities to mobilise their operations to respond to local sustainability challenges. In this instance, the success of such an approach is shown to depend on commitments from the university community and the availability of enabling inputs, such as financial and human resources. The paper concludes with reflections and recommendations to inform further development of a newly emerging systems approach in sustainability mainstreaming at Rhodes University, and other institutions pursuing similar approaches and goals.

- Description: Those of us who work in water resource management have found that very few knowledge/research resources are accessible to most people. This happens because resources are not disseminated properly (or at all), or because they are inappropriately technicist, or because potential readers are hampered by low education. What is the best way to make water research accessible to as many people as possible and especially to people whose lives would be affected by the research? In the early 1980s an attempt was made to address this issue when Robert Berold edited People's Workbook (EDA 1981), a user-friendly book that presented basic technical information for rural people – not only on water, but also on agriculture, health, building construction, and income generation. The book included real-life interviews, and was disseminated by rural fieldworkers. Perhaps because there was nothing like it at the time, it was enormously popular.

- Description: Objective: To assess the burden of iodine deficiency in pregnancy in Africa using estimated pregnancy median urinary iodine concentration (pMUIC). Design: pMUIC for each African country was estimated using a regression equation derived by correlating the school-age children (SAC) median UIC (mUIC) and pMUIC from countries around the globe, and the SAC mUIC data for African countries obtained from the Iodine Global Network (IGN) 2017 and 2019 Score cards. Setting: Iodine deficiency was endemic in many African countries before the introduction of iodine fortification, mainly through universal salt iodisation programmes about 25 years ago. There is a scarcity of data on the level of iodine nutrition in pregnancy in Africa. Women living in settings with pMUIC below 150 μg/l are at risk of iodine deficiency-related pregnancy complications. Participants: Fifty of the fifty-five African countries that had data on iodine nutrition status. Results: A cut-off school age mUIC ≤ 175 μg/l is correlated with insufficient iodine intake in pregnancy (pregnancy mUIC ≤ 150 μg/l). Twenty-two African countries had SAC mUIC less than 175 μg/l, which correlated with insufficient iodine intake during pregnancy (pMUIC less than 150 μg/l). However, nine of these twenty-two countries had adequate iodine intake based on SAC mUIC. Conclusions: There is likely a high prevalence of insufficient iodine intake in pregnancy, including in some African countries classified as having adequate iodine intake in the general population. A SAC mUIC ≤ 175 μ
