- Description: Zodwa Wabantu, a South African celebrity recently made popular by the Daily Sun, a local tabloid newspaper, is notorious as an older working-class woman who fearlessly challenges social norms of feminine respectability and beauty. Her assertion of sexual autonomy and her forays into self-surveillance and body-modification, mediated by the Daily Sun and other tabloid and social media platforms, could be read as a local iteration of a global postfeminist subjectivity. However, the widespread social opprobrium she faces must be accounted for: Using Connell’s model of the gender order together with a coloniality frame, I argue that northern critiques of postfeminism omit to consider the forms of patriarchy established by colonialism in southern locales such as South Africa. The local patriarchal gender order, made visible within the tabloid reportage, provides the context within which the meaning of Zodwa Wabanu’s contemporary postfeminist identity is constructed. I examine a range of Zodwa Wabantu’s (self)representations in Daily Sun and other digital media in the light of this context, and conclude that a close examination of the local gender order assists in understanding the limits of postfeminism’s hegemony.

- Description: In recent years there has been a growing focus internationally on the low participation of females in Economics, both in academia and business. While female enrolment in higher education, including other maths-based subjects, has grown substantially, this has not been the case for Economics. Economics, particularly as one progresses through postgraduate studies to doctoral degrees now stands out as an outlier. A number of reasons have been advanced for this, including the nature of the subject, the type of people it attracts and the lack of female role models. Male and female enrolments in South African HEIs have grown between 2007 and 2017, but females have grown at a faster rate, thus increasing the female share of total enrolments to 59%. Female students are more successful and so make up an even greater proportion of South African graduates. Female enrolments and graduates are also higher than in the US. As in the US there is a significant drop off in female representation when progressing from undergraduate to postgraduate studies in South Africa. When looking at Economics in South Africa in comparison to the broad CESM categories, female enrolment in Economics Bachelor degrees is significantly lower than in Business and Humanities, but on a par with STEM subjects. At the Doctoral level, there are sharp drop offs in female enrolments for all categories. Business and Economics are the laggards at the Doctoral level, below STEM and Humanities. Furthermore, females make up a minority of academic staff in South African HEIs, with males dominating in especially the higher academic ranks. As one moves up the academic ladder, the female share decreases. This research analyses gender compositions of staff and students at South African HEIs. National data are obtained from government publications and data relating to four specific South African universities was obtained directly from the universities. Questionnaires were sent to a sample of academic staff and students who are in the field of economics to identify whether there is a role model effect for economics students and whether female academics experience the same forms of biases, discrimination, or treatment as that identified in international studies. It was concluded that while there are drop offs in the overall female representation of students at the Masters and Doctoral levels in South Africa, this share is gradually increasing. Additionally, Economics seems to perform better than what is depicted in the US, and in comparison to some STEM subjects in South Africa. Furthermore, the environment within the field of academic economics for both female students and staff seems to be more positive than what the international literature depicts for the US. But there are nonetheless different levels of satisfaction between male and female academic economists. While the student surveys revealed that female Economics students do not attach great importance to female role models, there is some evidence of correlation between the percentage of female professors and the percentage of female PhD students across a range of STEM subjects in South Africa. , Thesis (MCom) -- Faculty of Commerce, Economics and Economic History, 2020

- Description: Product development using quality by design is a proactive and risk-based approach that shifts the manufacturing process from empirical to science-based. Risk assessment was performed to identify and analyse risk areas for the manufacture of captopril pellets. Twelve experimental runs were performed using a Plackett-Burman screening design. Pareto plots revealed the effect of formulation and process variables on the responses monitored and facilitated the identification of the most critical parameters for optimization of the formulation. A response surface methodology approach in conjunction with a central composite design was used to optimize the Eudragit® RL 30D (15-30 ml), microcrystalline cellulose (20-40 % w/w), sodium starch glycolate (2-5 % w/w) and spheronizer speed (650-1050 rpm).

- Description: Dental development and eruption sequences have prevailed as the gold standard in age estimations of previously unidentified immature individuals within a legal context. However, in the absence of the dentition, skeletal assessments have served as a frequently applied alternative. While various cranial and postcranial skeletal elements have been used in estimating age of the immature skeleton, little is known about the anthropometric value of the pars basilaris, pars lateralis and femur as skeletal age estimation tools. Thus, this study aimed to assess if these bones of the immature human skeleton were useful elements in estimating the age of prenatal and postnatal individuals. These bones were excised from the remains of 74 unclaimed human immature individuals and evaluated using traditional anthropometric methods. The study sample was sourced from the Johannesburg Forensic Pathology Services (JFPS) and the Johannesburg Forensic Paediatric Collection (JFPC), University of the Witwatersrand and subdivided into an early prenatal (younger than 30 gestational weeks); late prenatal (30 to 40 gestational weeks) and postnatal (birth to 7.5 months) age ranges.

- Description: Understanding molecular mechanisms underlying the complexity of allosteric regulation in proteins has attracted considerable attention in drug discovery due to the benefits and versatility of allosteric modulators in providing desirable selectivity against protein targets while minimizing toxicity and other side effects. The proliferation of novel computational approaches for predicting ligand–protein interactions and binding using dynamic and network-centric perspectives has led to new insights into allosteric mechanisms and facilitated computer-based discovery of allosteric drugs. Although no absolute method of experimental and in silico allosteric drug/site discovery exists, current methods are still being improved. As such, the critical analysis and integration of established approaches into robust, reproducible, and customizable computational pipelines with experimental feedback could make allosteric drug discovery more efficient and reliable. In this article, we review computational approaches for allosteric drug discovery and discuss how these tools can be utilized to develop consensus workflows for in silico identification of allosteric sites and modulators with some applications to pathogen resistance and precision medicine. The emerging realization that allosteric modulators can exploit distinct regulatory mechanisms and can provide access to targeted modulation of protein activities could open opportunities for probing biological processes and in silico design of drug combinations with improved therapeutic indices and a broad range of activities.

- Description: In this era of precision medicine, insights into the resistance mechanism of drugs are integral for the development of potent therapeutics. Here, we sought to understand the contribution of four point mutations (N51I, C59R, S108N, and I164L) within the active site of the malaria parasite enzyme dihydrofolate reductase (DHFR) towards the resistance of the antimalarial drug pyrimethamine. Homology modeling was used to obtain full-length models of wild type (WT) and mutant DHFR. Molecular docking was employed to dock pyrimethamine onto the generated structures. Subsequent all-atom molecular dynamics (MD) simulations and binding free-energy computations highlighted that pyrimethamine’s stability and affinity inversely relates to the number of mutations within its binding site and, hence, resistance severity.

- Description: Asymmetric mono-carboxy-porphyrins, (5-(4-carboxyphenyl)−10,15,20-tris(pentafluorophenyl)porphyrinato zinc(II) (1), 5-(4-carboxyphenyl)−10,15,20-triphenylporphyrinato zinc(II) (2) and 5-(4-carboxyphenyl)−10,15,20-tris(2-thienyl)porphyrinato zinc(II) (3), were linked to Ag nanoparticles (AgNPs) through amide bonds and self-assembly (the latter only for 3). The porphyrins and conjugates were used for photodynamic antimicrobial chemotherapy (PACT) against Staphylococcus aureus. PACT uses singlet oxygen for antimicrobial activity. Complex 3 and its conjugates had higher singlet oxygen quantum yields and higher log reduction when compared with the rest of the porphyrins and corresponding conjugates. These high log reductions for 3 and its conjugate were attributed to the presence of sulfur groups whereby there was more interaction with the bacterial membrane.

- Description: Asymmetric mono-carboxy-porphyrins, (5-(4-carboxyphenyl)−10,15,20-tris(pentafluorophenyl)porphyrinato zinc(II) (1), 5-(4-carboxyphenyl)−10,15,20-triphenylporphyrinato zinc(II) (2) and 5-(4-carboxyphenyl)−10,15,20-tris(2-thienyl)porphyrinato zinc(II) (3), were linked to Ag nanoparticles (AgNPs) through amide bonds and self-assembly (the latter only for 3). The porphyrins and conjugates were used for photodynamic antimicrobial chemotherapy (PACT) against Staphylococcus aureus. PACT uses singlet oxygen for antimicrobial activity. Complex 3 and its conjugates had higher singlet oxygen quantum yields and higher log reduction when compared with the rest of the porphyrins and corresponding conjugates. These high log reductions for 3 and its conjugate were attributed to the presence of sulfur groups whereby there was more interaction with the bacterial membrane.

- Description: Writers as diverse as Oscar Wilde (1915), Matthew Arnold (1960), Erich Fromm (1997) and a proliferation of contemporary self-help gurus, variously assert that it is preferable for people to focus on “being”, or to value “who you are”, instead of emphasising “having” or the material possessions you have acquired. These discourses assert that individuals content with “being” are happier and more fulfilled than those involved in the constant (and alienating) motion of acquiring material goods as representations of themselves (de Botton, 2004; Fromm, 1997; James, 2007). This thesis provides an in-depth critical exploration of one of these ideal “ways of being”: authenticity. It does not seek to discover what authenticity is in an empirical sense, nor to define what it should be in a normative sense, but to map the cultural work done by changing and often contradictory discourses of personal authenticity. More specifically, this study uses a qualitative research design, social constructionist theoretical framework, and discourse analytic method to critically discuss the discursive constructions of subject authenticity in South African brand culture. The sample consisted of (1.) ten marketing campaigns of several large, mainstream brands, which were popular in South Africa from 2015 to 2017, and (2.) fifteen smaller South African “craft” brands popular in the “artisanal” context. The analysis is presented in two distinct, but interrelated, sections (namely, Selling Stories and Crafting Authenticity), where the relevant discourses of authenticity for each data set are explored in depth. Through this analysis the thesis provides a critical discussion of the ways in which these discourses of authenticity work to produce and maintain, (or challenge and subvert), subject positions, ideologies, and power relations that structure contemporary South African society.

- Description: Language-in-education policy in South Africa is underpinned by the Constitution. The gap that this research addresses is the inconsistency of policy implementation and the actual teaching of isiXhosa in primary schools. It analyses the official and overt language policy and the (covert) language practices at schools. Semi-structured interviews were conducted with language teachers and principals. Data were also gathered from classroom observations and document analysis in the Eastern Cape and Gauteng. On the one hand, there are standard language policy documents that exist. These advocate for English as a language of learning and teaching and isiXhosa as a subject. On the other hand, the daily reality in classrooms partly reflects this policy implementation.

- Description: The aim of this research was to understand university students’ self-reported reading practices. The students attended the University of Fort Hare in South Africa, a historically black institution in a rural and under-resourced setting. A framework of New Literacy Studies (NLS) was used to understand students’ self-reported reading practices and the links between these and their identities. Tools provided by Gee, 2005, Gee, 2011 were applied to conduct a CDA of focus group discussions. In the ‘We Blacks’ Discourse, interviewees ‘othered’ the idea of reading as not being culturally valued. It was closely allied to the ‘Resistance to Reading’ Discourse, as participants explained that they tended to disregard books and did not enjoy leisure reading. The ‘Better Than Us’ discourse was drawn upon to suggest that reading was associated with attitudes of superiority. These discourses tended to homogenise class and other differences between black students and indicated the ways in which their experiences made adopting academic identities difficult. The analysis suggests that the racism of the past continues to impact students’ reading identities. The article concludes that the effects of these and related discourses require a response across the education sector, and transformative pedagogies might be needed in higher education.

- Description: In their official language policy, nearly all Sub-Saharan African states use their indigenous language(s) as Language of Learning and Teaching (LoLT) only at the beginning of primary schools. This is also the case in Malawi. The curricula in the various school subjects are also highly dominated by ‘Western’ ideas and include very little Indigenous Knowledge (IK). Nevertheless, indigenous languages are frequently used during lessons. This research focused on answering the following questions: How is a meaningful Science Education for pupils in Malawi possible? Does the inclusion of IK and teaching through African Languages assist pupils in any way? Research was done in the Northern Region of Malawi. To obtain a better understanding, semi-structured interviews and ethnographic observations were conducted. The main focus of these interviews was on the subject of ‘Agriculture’.

Demonstrating that symbolic spaces such as these have increasingly become the location of choice for the practice and performance of contemporary politics in the last decade, the book shows how this has led to the securitization of urban public space. Highlighting specific changes that have been made, such as the installation of closed-circuit television or the limitation of access to certain streets, plazas and buildings, the book analyses the impact of different approaches to securitization.

- Description: Arid environments provide ideal ground for investigating the mechanisms of adaptive evolution. High temperatures and low water availability are relentless stressors for many endotherms, including birds; yet birds persist in deserts. While physiological adaptation probably involves metabolic phenotypes, the underlying mechanisms (plasticity, genetics) are largely uncharacterized. To explore this, we took an intraspecific approach that focused on a species that is resident over a mesic to arid gradient, the Karoo scrub‐robin (Cercotrichas coryphaeus). Specifically, we integrated environmental (climatic and primary productivity), physiological (metabolic rates: a measure of energy expenditure), genotypic (genetic variation underlying the machinery of energy production) and microbiome (involved in processing food from where energy is retrieved) data, to infer the mechanism of physiological adaptation. We that found the variation in energetic physiology phenotypes and gut microbiome composition are associated with environmental features as well as with variation in genes underlying energy metabolic pathways. Specifically, we identified a small list of candidate adaptive genes, some of them with known ties to relevant physiology phenotypes. Together our results suggest that selective pressures on energetic physiology mediated by genes related to energy homeostasis and possibly microbiota composition may facilitate adaptation to local conditions and provide an explanation to the high avian intraspecific divergence observed in harsh environments.

- Description: In 2007, a former South African Defence Force (SADF) paratrooper, Marius van Niekerk, embarked on a journey to confront his shameful memories relating to his role in the Angolan Civil War. From Sweden (where he had gone into exile), Van Niekerk returned to Angola, where he had been deployed during the mid-1980s, and recruited three other veterans of the war to join his party: Patrick Johannes, who had been coerced to fight for the Popular Armed Forces for the Liberation of Angola (FAPLA); Samuel Machado Amaru, who was forcefully enlisted by the National Union for the Total Independence of Angola (UNITA); and Mario Mahonga, who had fought for the Portuguese colonial army before he was recruited by the SADF to fight against the Popular Movement for the Liberation of Angola (MPLA) regime. Van Niekerk had been conscripted at the age of seventeen, and the others had been coerced into their respective militias at more tender ages. It is not clear how the three Angolans were induced to participate in the project, whose objectives they evidently did not share.

- Description: The synthesis and characterization of a novel BODIPY dye functionalized with bis-boronic acid groups to enable direct glucose sensing through selective recognition of carbohydrates is reported. Styrylation with boronic acid groups at the 3,5-positions of the BODIPY core results in an extension of the π-conjugation system of the dye and in a red-shift of the main absorption band from 500 to 637 nm. The functionalized BODIPY dye was adsorbed on a glassy carbon electrode using the drop and dry method. Modified and bare electrodes were characterized using cyclic voltammetry and scanning electrochemical microscopy, while glucose detection was carried out by using differential pulse voltammetry and chronoamperometry. The detection limit was determined to be 1.42 μM. The dye was found to be selective and sensitive towards glucose, since likely interferences have only minor effects on the glucose detection.

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