- Description: Shallow coastal marine ecosystems provide important resources to society but are increasingly under threat from anthropogenic impacts. These systems form an interface between land and sea, providing valuable resources. Global environmental change, overexploitation, habitat transformation, pollution and policies aimed at short-term socio-economic gains are driving the loss of natural resources, productivity and biodiversity. Consequently, a comprehensive and holistic understanding of the current and future states of marine ecosystems is essential. This requires insight into the processes involved in maintaining genetic, species, habitat, community and biotope diversity at an ecosystem level. An understanding of ecosystem processes and the ability to detect changes in biodiversity, biotopes, seascape composition and ecosystem functioning require observation made over time and space. In response to this need, Long-Term Ecological Research (LTER) programmes such as those established by the South African Environmental Observation Network (SAEON) supported by the Department of Science and Innovation’s (DSI) Shallow Marine and Coastal Research Infrastructure (SMCRI) collect long–term observational data from different environments and systems. This study aimed to evaluate data collected as part of the developmental phase of a newly established benthic research platform. The datasets constructed are used to develop a baseline description of the benthic biotopes of two study areas within Algoa Bay. It aimed to gain insight into the feasibility of the methods used and the value of the data and derived essential biological variables (EVB). Assessing the sustainability of the programme over time was done through a practical evaluation of the methodology to be used and the technical feasibility of data collection and analysis. It furthermore aimed to assess the data usefulness in describing biodiversity at various scales and its sensitivity in reporting change. This pilot study provides valuable insight into data collection methodologies and introduces new sampling platforms. The baseline dataset consisted of data collected during the first 18 months of the SAEON Benthic Ecosystem Long-Term Ecological Research (BELTER) platform in Algoa Bay, Agulhas ecoregion, Western Indian Ocean, South Africa. This comprised of the collection of images for 150 m2 of the researched benthic seascape and 306 stereo video data streams. The 77 760 point dataset allowed the identification of 12 substrate types, 7 biotopes, 44 sub-biotope units, 377 sessile and sedentary benthic species and 51 ichthyofauna species. The described habitat and benthic communities and the defined benthic biotopes allowed for the assessment of biotope heterogeneity and the construction of a provisional distribution map for the broader biotopes. This work includes a study into the infra- and supra-benthic ichthyofauna associated with the defined biotopes and investigates the role habitat and benthic communities play in the distribution of these fish 3 assemblages. Lastly, it assesses the value of morphological traits and diversity indices for describing and comparing abiotic and biotic components of observed systems within the shallow coastal marine seascape. This study shows that species composition differs significantly between biotopes with habitat type playing a key role in the composition of the benthos. Substrate type, consolidated or unconsolidated, depth and the composition of the soft sediment is the most important determining factors. The White Sands Reef station has a higher species diversity than the St Croix Island Complex station with a higher percentage cover associated with the hard substrate. The dissimilarity between biotopes and communities are generally high although similarity within the biotopes or communities was found to be relatively low. This was considered indicative of high heterogeneity within the biotopes and a patch or mosaic-like distribution of communities within the broader biotope. A fine-scale a posteriori analysis of the data collected confirmed the high heterogeneous nature of both habitat and communities within the broader biotope. The description of the abiotic and biotic variables resulted in the identification of a diverse suite of biotope subunits. The character of the biotope hinges not only on the composition of the substrate and biota present but the contribution of smaller distinct biotopes subunits, their distribution and representation within broader biotopes and the degree these are shared with other broader biotopes. The distribution of these biotope units at different scales is believed to be important in understanding inherent diversity, niche partitioning and connectivity within a highly heterogeneous seascape. Ichthyofauna associated with the broader biotopes were indicative of the substrate type. Low profile reef systems with interspaced sandy stretches supported both reef fish and those typically associated with sandy substrates. Benthic biotopes associated characteristically with higher profile reef systems and less sand or soft sediment were mainly utilized by reef-associated fish species. Substrate type, depth and seasonality were found to be important factors in the observed composition and distribution of ichthyofauna over the seascape. Although fish species were found to have a wide distribution and made use of multiple biotopes the average abundance of the species within the observed assemblages differed. Analysis of ichthyofauna species composition indicated that observed fish assemblages were homogeneous within five of the seven biotopes. Broader biotopes that were found to be significantly different between sample locations are characterised by a diverse complement of biotope subunits and are highly heterogeneous. Traits and diversity indices are important tools for assessing and comparing different systems within the seascape, both spatially and temporally. The classification of the biota into broader phylogenetic groups indicated a significant difference between biotopes. This is especially useful when detailed 4 analysis or species identification is not possible or the skill set is not available. Morphological traits included in this study informed on the physical structure of the communities present and in combination with substrate type provided insight into the three-dimensional structure of the biotope. Species diversity, abundance, density estimates and the Shannon-Weiner diversity index were found to be the most useful diversity indices characterising and comparing biotopes. This was less so for ichthyofauna. Significant differences in the number of species observed were evident only between consolidated and unconsolidated dominated substrates. Although there was no significant difference in the number of individuals observed, both the Shannon-Weiner and Simpson Diversity indices were able to highlight differences in the fish assemblages observed for the different biotopes. The data collected, although permitting a comprehensive baseline assessment of the benthic environment for two research stations within the SAEON Algoa Bay LTER Sentinel Site, is temporally limited. The ichthyofauna dataset used was small and it is understood that the addition of length-frequency analysis of observed ichthyofauna will benefit our understanding of the biotope use by infra- and supra-benthic fish species over their life history within the larger seascape. Seasonal differences were evident and it is expected that datasets spanning several years, including LTER stations within different marine ecosystems types, will provide valuable insights on system dynamics in the short and long term both spatially and temporally. This study is the first attempt to evaluate the methodology developed and data collected in the South African Environmental Observation Network’s, Elwandle Coastal Node as part of the Shallow Marine and Coastal Research Infrastructure Benthic Ecosystem Long-Term Ecological Research (BELTER) platform. Newly designed and developed sample equipment and a sampling regime allowed for the collection of data on a long-term basis. The study was successful in the description of the biotope and biotope subunits for two research stations in Algoa Bay. It permitted the construction of comprehensive species lists for both benthic sessile and sedentary biota and the associated ichthyofauna. The subset of data used was successful in reporting on both spatial and temporal change. This work demonstrates that in the absence of detailed species identifications, traits may be used to describe habitat and community structure and report on abiotic and biotic biotope characteristics. This study furthermore allowed for the comparison of a comprehensive suite of diversity indices highlighting indices that may be especially useful in routine BELTER reporting. , Thesis (PhD) -- Faculty of Science, Ichthyology and Fisheries Science, 2021

- Description: This study sets out to explore the meaning, extent, and impact of the generational divide, between so-called Baby Boomers and their Millennial offspring, on the way news is accessed, consumed, shared, and produced in five purposively selected households in the Johannesburg area. Aside from these widely-used generational identifiers, Baby Boomers and Millennials are also commonly referred to as Digital Immigrants and Digital Natives, respectively. However, in a world where smartphones have become commonplace, and internet connectivity via fixed broadband and mobile data is ubiquitous, it can be argued that digital technologies now serve as a link, or perhaps even a bridge, between younger and older generations living in the same household. The study aims to put this proposition to the test, by interrogating the role of news as a conduit for storytelling and information-sharing in environments where each occupant will typically be using their own devices, with a wide variety of personally-curated news sources and platforms at their fingertips. This fragmentation or individualisation of access to news stands in sharp contrast to the communal traditions of the pre-Internet era, during which families would gather around the TV set to watch the evening newscast, or share sections of the Sunday newspaper according to their age and interest. This research, which seeks to address a gap in the literature of research into intra-generational news consumption in family households in the digital era, identifies points of intersection as well as diversion in media usage habits. An example of the former is the prevalence of WhatsApp as a centralised "meeting-point" for the sharing of useful, hyper-localised information within the family group, and beyond that, as a cross-generational news and discussion platform in its own right. On the opposite end of the spectrum, the study explores strict and seemingly counterintuitive divides between the generations, with some Millennial respondents rejecting social media platforms as "pointless and invasive, and some Baby Boomer parents embracing the platforms as forums for free expression and networking. In line with the key research question, which seeks to identify and analyse news usage and consumption across the generations in a selection of family households, the study considers the ways in which families in the digital era are creating a culture of shared interests and the active sharing of news, breaching the boundaries of their private spaces in a microcosm of the Habermasian public sphere of discourse and opinion. , Thesis (MA) -- Faculty of Humanities, Journalism and Media Studies, 2021

- Description: This thesis consists of an exploration of the interaction between language and the thing in itself in the fiction of John Banville. The thing in itself is that which exceeds the text and to which it cannot refer, even as it is compelled to do so. In exploring this tension, the thesis focuses on how Banville’s writing, in foregrounding the inadequacy of the literary text, makes the reader aware of the existence of what exceeds it. Each of the chapters in the study examines the various strategies through which Banville gestures beyond the text in spite of the limitations placed upon him by form and genre. The first chapter studies the tendency in this writer’s texts to view death as an apotheosis of the soul in which the individual finally has access to the thing in itself, which they had previously encountered as infants before entering language. The second chapter examines how elements of Romantic thought, such as nostalgia, the seniority of the child over the adult and a particular impression of the natural world, contribute to Banville’s attempt to gesture towards the thing in itself. In the third chapter, the role of language in distorting one’s understanding of the other is examined. The final chapter of the thesis examines the narrative strategies (including mise en abyme, ekphrasis, metaphor and catachresis) Banville uses in order to present the reader with excess. Ultimately, this study suggests that Banville uses various narrative strategies to make his reader aware of that which exists outside of the text. By gesturing beyond the novel to the sublime, and by self-reflexively exposing the inner workings of the writing process to the reader, Banville’s texts confront the reader with an intimation of ineluctable excess. , Thesis (MA) -- Faculty of Humanities, Literary Studies in English, 2021

- Description: In an effort to move away from Apartheid and its evils -South Africa and South Africans have committed to a shared moral project -the Rainbow Nation-Building Project (RNP); a project that confers certain moral duties and responsibilities upon its citizens, including a joint commitment to robust inclusivity, equality, and unity. Importantly, however, our environments –be they physical, social, or psychological –are such that they (actively or passively) obscure our awareness of some morally relevant facts about our society, and thereby hinder us as moral agents and therefore threaten our abilities to fulfil our moral project and commitment.What does it mean for us -a society ostensibly committed to the RNP -to be plagued by racism, sexism, queerphobia and xenophobia? What is it that contributes to our complicity regarding social practices and ideas that we would otherwise find morally objectionable? What does it say about our commitment to our publicly-exalted ideals and values (of inclusivity, diversity, reconciliation, justice, and unity) when we are unwittingly complicit in the marginalisation and social exclusion of members of our society? And how can institutions such as universities work to overcome this?In this work, I argue that the obscuring of, and failure to perceive, morally relevant facts that call on us for ethical attention and/or action -a phenomenon I refer to as ‘moral blindness’ -is responsible for at least some of our behaviours and practices that run contrary to our moral ambitions; and therefore has profound implications for us as moral agents and our ability to succeed in our moral goals. Moral blindness, then, is both an epistemic and ethical concern that enables socially unjust systems to perpetuate themselves; and is thus a threat toallmoral projects.I argue that, for South Africa, much of what can be identified as moral blindness is the direct result of the shifting and conflicting socio-cultural conditions the nation finds itself liminally caught amidst in its transition from its Apartheid past and towards its promised inclusive Rainbow Nation future. Commitment to the RNP, I argue, involves a self-transformation and habituation of certain supportive virtues on the part of South Africans to become the kinds of people who are compatible with the Rainbowist society -whom I call Rainbow Citizens. But this self-transformation itself is also a moral project, and therefore subject to the threat that moral blindness presents, and so too can be failed. If all this is true, then it seems that if we do not take moral blindness seriously, we could ultimately fail to become South African. , Thesis (MA) -- Faculty of Humanities, Philosophy, 2021

- Description: The South African abalone, Haliotis midae, is a commercially important species of mollusc which contributes significantly to the value of the South African mariculture industry. One of the primary challenges experienced by abalone farmers is the consistent production of juvenile abalone (spat) in sufficient volumes to keep stocking farms and facilitate expansion of the industry. One of the key production bottlenecks of H. midae is achieving adequate levels of larval attachment and metamorphosis (settlement). The larvae of H. midae are settled on polycarbonate plates which have been pre-conditioned with biofilms in seawater which is pumped ashore onto farms. The seasonal variability in settlement success reported by hatchery managers in South Africa is hypothesised to be as a result of different diatom species compositions colonising the settlement plates at different times of the year, with settlement success being lowest during the winter months. The following study investigated whether the addition of conspecific mucous to biofilms could result in elevated settlement success, and whether there was potential for sterilisation of this mucous. A novel method of mucous application, spraying it onto the plates as opposed to pre-grazing, was tested in settlement assays and the trials revealed the following results: • The addition of H. midae mucous induced significantly more larvae to attach to settlement plates, when mucous was harvested around the spawning season. • Elevated attachment of larvae on mucous treated plates did not result in more post-larvae occupying the plates at the end of trials, and increased mortality is likely attributed to introduction of pathogens in conjunction with mucous. • No increase in the final proportion of settled larvae which had metamorphosed or the rate at which they metamorphosed was observed between mucous application treatments and biofilm only treatments. Subsequent trials assessed whether methods of mucous handling could reduce the biosecurity risk associated with mucous use, and so mucous was either UV irradiated or autoclaved. These trials revealed the following findings: • No difference in attachment was seen between any treatments, including the untreated mucous. This is contrary to the findings of our initial experiments and illustrates that the attachment-inducing properties within mucous may be seasonally expressed. ii • Numbers of observed larvae/post-larvae on plates applied with UV and autoclaved mucous where less stable than biofilms only, especially in the second trial, illustrating that mucous still presents a biosecurity risk even after undergoing these handling methods as it may act as a substrate on which pathogenic bacteria could colonise. , Thesis (MSc) -- Faculty of Science, Ichthyology and Fisheries Science, 2021

- Description: This study contributes to the literature on quality improvement in higher education by examining the structural, cultural and agential constraints and enablements on a quality process at a university in South Africa. It examined four cases and developed an understanding of the complex interaction of structure, culture and agency and the mechanisms that enable or constrain quality improvement in higher education. The study drew on the literature on higher education quality for the theoretical basis for what is known contributes to the way in which quality assurance and improvement is implemented and its impact on the higher education context. Critical Realism provided the ontological framework and conceptual tools to understand and explore the complex social world within which the quality process took place. The literature on the morphogenetic approach provided the analytical framework for the data analysis and findings. The data consisted of a set of documents from a quality process that took place over a five-year period. The data analysis revealed that different departmental contexts impact on how mechanisms are activated. Each school context shapes the way in which people engage with the review process and consequently, processes and procedures are mediated in each context. This research therefore adds to the understanding of the way in which quality processes take place at a micro-level within an institutional context and informs the approach to quality improvement more broadly, nationally and internationally. The research contributes to the knowledge that will inform planning, policies and practices in quality improvement processes in higher education and the findings identify a number of factors (mechanisms) that should inform the way in which a quality process is facilitated, will enable effective self-evaluation and review processes, and consequently are more likely to lead to quality improvement. , Thesis (PhD) -- Faculty of Education, Centre for Higher Education Research, Teaching and Learning, 2021

- Description: Doctoral studies are described as a process of formation and becoming. This is an in-between space between unknowing and knowing, within and without the ivory tower of academia. In this in-between space the doctoral candidate takes the role of a novice and apprentice unlearning the student/unknowing past and learning to become a professional in academia. This project utilises the borderlands theory to understand the experiences of doctoral students as they undergo the process of becoming and intellectual identity formation. Whilst ‘journey’ and other metaphors that have been used to understand doctoral student experiences capture the process of becoming as a progression through the liminal stages – proposal, literature review, context, writing, reading etc. These stages presuppose temporality of being leading to stasis/completion. I argue that such conceptualisation of doctoral studies, although useful, depict one side of the story and provide a limited, monolithic, and homogenising understanding of the spatial configurations of doctoral space and intellectual identity formation. The dominant discourses of doctoral conceived and perceived space, liminal stages and understanding of doctoral student experiences, mask the more latent and intimate liminal stages of intellectual identity formation. Drawing from borderlands theory, I firstly argue for a holistic approach to understanding the spatiality of doctorate studies. Secondly, I argue that liminality is an everyday process integral to human existence where one is always in a state of ideological transition. An important state of liminality is the awareness of ‘Self’ in perpetual motion, caught between two worlds dominated/dominator and two ideologies of oppression/resistance. If this side of liminality is not made visible, institutional spaces, such as the doctorate, privileged with the power to disseminate and position onto-epistemologies as universal can be used to reproduce and reinforce exclusionary onto-epistemologies that subsequently impact intellectual identity formation. Using Lefebvre’s (1991) rhythmanalysis method, I use student experiences not as mere data for analysis, but as an act of envisioning, reinventing and coknowledge production to propose borderlands as a new metaphor to study doctoral spatial realities and the experiences of the students that traverse through it. , Thesis (PhD) -- Faculty of Humanities, Politics and International Studies, 2021

- Description: The persistence of personal identity stands at the heart of many human practices, such as paying individuals for their work or holding people responsible for their actions. As such, it seems important that theories of personal identity are able to account for the practical implications of continuity of personal identity. Mindful of the practical importance of personal identity, Marya Schechtman (1994) argues that her narrative view only accounts for the four features that persons must possess. Any account of personal identity is supposed to make persons capable of possessing these features. She then posits her narrative self-constitution view as an account of personal identity she feels is capable of explaining the link between personal identity and certain features of persons. In this thesis project, I present how the narrative views, as described by Schechtman and others, are interpretive enterprises and that this leads them to a potentially devastating conclusion. The narratives must be constructed from something, and I argue that it is memory. But empirical facts about memory do not allow for it to persist in a quantitative way, but rather in a qualitative way, much like persons. Upon making this argument, I further argue that if mainstream psychological views is correct, this reduces the persistence of memory to resemblance relations. And memory is the building blocks of narrative. If this is the case, then narrative is also reduced to resemblance relations. Narrative, therefore, does not persist through time in a non-qualitative way, and one is better off accepting a psychological theory by virtue of parsimony. Ultimately, I argue that Schechtman and narrative theorists may save narrative views by adopting what I call as a ‘causal narrative view’. A causal narrative view will encapsulate all of the relevant features of the typical narrative view, including the emphasis on construction, but will also add the addendum that narrative states must be placed in a causal relation to each other. , Thesis (MA) -- Faculty of Humanities, Philosophy, 2021

- Description: Background: The prevalence of Substance Use Disorders (SUDs) amongst the genderqueer population is a huge concern in the public mental health system. The genderqueer population’s help-seeking barriers have been attributed to SUD treatment centre’s questionable ability to be responsive to the unique mental health needs of genderqueer individuals. Aim: The aim of this study is to conduct a systematic review on mental healthcare workers‟ responsiveness and gender-sensitivity towards the genderqueer population in SUD treatment centres. Methods: Employing the Joanna Briggs Institute’s (JBIs) systematic review method, 25 qualitative articles were included in this study. A thematic analysis was used to examine the data. Results: The analysis revealed that SUD treatment centres are experienced as discriminatory and unreceptive by the genderqueer population due to several barriers. The barriers identified were structural, financial, personal, cultural and the use of a heterosexual framework to treat SUD which led to abuse, isolation, and stigma. Mental healthcare providers lack skills in working with genderqueer individuals as well as a lack of knowledge on genderqueer related needs. Lack of gender sensitivity affects genderqueer individuals in accessing SUD treatment centres and the progress they make. This magnified the need and importance of specialised gender-responsive and gender-sensitive training in working with genderqueer individuals. Twelve interventions to address the areas of difficulty were identified. , Thesis (MA) -- Faculty of Humanities, Psychology, 2021

- Description: Freshwater crayfish have become one of the most widely introduced freshwater taxa globally. Crayfish introductions have not spared the African continent, which, apart from Madagascar, is naturally devoid of native freshwater crayfish. These introductions are of concern because invasive crayfish have generally been shown to cause strong impacts on recipient ecosystems outside Africa. This study therefore set out to compile up-to-date information regarding crayfish introductions in Africa, their pathways and distributions and to improve our understanding of the nature and magnitude of their environmental impacts. A systematic review revealed that nine crayfish species have been introduced into the continent with five of those, Astacus astacus, Cherax quadricarinatus, Faxonius limosus, Procambarus clarkii and Procambarus virginalis, having established naturalised populations in fourteen African countries (Chapter 2). The main driver of these crayfish introductions was to provide socio-economic benefits but there is limited evidence of success. The thesis further documents attempts made to address crayfish knowledge gaps in Africa, including standardisation of C. quadricarinatus sampling gear (Chapter 3), determination of the distribution of C. quadricarinatus in the recently invaded Upper Zambezi Basin (Chapter 4), and predicting ecological and socioeconomic impacts of two crayfish species that are spreading rapidly in Southern Africa, namely, C. quadricarinatus and P. clarkii (Chapters 5 – 8). To standardise C. quadricarinatus sampling methods in Africa, two methods used in Southern Africa were compared and the Promar® collapsible trap baited with dry pellets was recommended as the best approach for C. quadricarinatus abundance studies due to the high catch per unit effort (CPUE), probability of capture and the suitability of dry dog food as a standard bait. This standard approach was used for crayfish surveys in the Zambezi Basin to comprehensively determine the spread and establishment of C. quadricarinatus across the basin. The establishment of C. quadricarinatus in the Barotse Floodplain, Upper Zambezi Floodplains freshwater ecoregion was confirmed. Although the probability of capture and catch per unit effort (CPUE) of C. quadricarinatus in the Barotse floodplain were similar to that of older invasions in the basin (Lake Kariba and Kafue River), morphometric differences among C. quadricarinatus populations sampled from these invaded regions were detected. Although crayfish were not detected in other regions, for example, the Okavango Floodplains ecoregions, C. quadricarinatus have the potential to spread at a downstream and upstream rate of 49 and 12 km·year-1, impacting native biota therein. To evaluate the potential for ecological impacts, the consumer-resource dynamics of C. quadricarinatus and P. clarkii were described in comparison to a native trophic analogue, the freshwater crab of the Potamonautes genus, preying on various native taxa ubiquitous to African aquatic and terrestrial ecosystems. The use of functional response (FR) and consumption experiments in this study showed the potential impacts of the two crayfish species on native resources and on resources that support livelihoods in invaded ecosystems. This in most cases was a result of their high attack parameter, which also resulted in high functional responses ratios (FRRs) compared to native crabs. The crayfish FR, FRRs and consumption rates were mostly enhanced under the high temperature treatments. The FRs and consumption results were then combined with the field biomasses of crayfish and crabs to calculate the relative impact potential (RIP) to successfully predict the degree of impact caused by crayfish species relative to crabs. Crayfish species consistently displayed RIP scores > 1 relative to the native crab irrespective of region, which were higher for the summer than the winter season, suggesting greater impact of the invaders compared to the native species. This study further estimated the socioeconomic losses due to catch spoilage by C. quadricarinatus which are up to 1500 t per year in the invaded Kafue River Basin, which translates to an annual income loss of US$ 2 million. Information provided in this study is vital for conservation management and to compel policymakers to develop appropriate conservation management tools within regulatory frameworks, which could stop or minimise the spread of crayfish species and protect Africa from further losing aquatic biodiversity. , Thesis (PhD) -- Faculty of Science, Ichthyology and Fisheries Science, 2021

- Description: Freshwater crayfish have become one of the most widely introduced freshwater taxa globally. Crayfish introductions have not spared the African continent, which, apart from Madagascar, is naturally devoid of native freshwater crayfish. These introductions are of concern because invasive crayfish have generally been shown to cause strong impacts on recipient ecosystems outside Africa. This study therefore set out to compile up-to-date information regarding crayfish introductions in Africa, their pathways and distributions and to improve our understanding of the nature and magnitude of their environmental impacts.

- Description: Surveys are an essential tool for collecting data and most surveys use complex sampling designs to collect the data. Complex sampling designs are used mainly to enhance representativeness in the sample by accounting for the underlying structure of the population. This often results in data that are non-independent and clustered. Ignoring complex design features such as clustering, stratification, multistage and unequal probability sampling may result in inaccurate and incorrect inference. An overview of, and difference between, design-based and model-based approaches to inference for complex survey data has been discussed. This study adopts a model-based approach. The objective of this study is to discuss and describe the modelling approach in analysing complex survey data. This is specifically done by introducing the principle inference methods under which data from complex surveys may be analysed. In particular, discussions on the theory and methods of model fitting for the analysis of complex survey data are presented. We begin by discussing unique features of complex survey data and explore appropriate methods of analysis that account for the complexity inherent in the survey data. We also explore the widely applied logistic regression modelling of binary data in a complex sample survey context. In particular, four forms of logistic regression models are fitted. These models are generalized linear models, multilevel models, mixed effects models and generalized linear mixed models. Simulated complex survey data are used to illustrate the methods and models. Various R packages are used for the analysis. The results presented and discussed in this thesis indicate that a logistic mixed model with first and second level predictors has a better fit compared to a logistic mixed model with first level predictors. In addition, a logistic multilevel model with first and second level predictors and nested random effects provides a better fit to the data compared to other logistic multilevel fitted models. Similar results were obtained from fitting a generalized logistic mixed model with first and second level predictor variables and a generalized linear mixed model with first and second level predictors and nested random effects. , Thesis (MSC) -- Faculty of Science, Statistics, 2021

- Description: This case study explored how schools and teachers interpret and implement the Language in Education Policy for their classroom practices. Scholars like Alexander and Block (2012) note that the South African Language in Education Policy (LiEP) is one of the advanced policies globally. Other scholars like Perry (2015) and Ngcobo (2015) state that the policy in South Africa has failed when it comes to implementation. It is against this background that the research explored how schools and teachers interpret and implement the Language in Education Policy for their classroom practice in three primary schools in Kuruman, Northern Cape. The research methodology was qualitative and it used a case study approach. The study is informed and framed by the Language Policy framework and the CDA (Critical Discourse Analysis). The research sites were three Grade 4 classes and the participants were three teachers, three principals and three SGB Chairpersons from three different schools (one school in deep rural, another in semi-urban and the third in urban) in Kuruman. This case study, located in the interpretive paradigm, employed individual semi-structured interviews, non-participant classroom observations, document analyses and field notes for data collection. The study revealed that teachers are not versed in LiEP and their classroom practice is therefore not based on policy but on their own perceptions. Classroom practices were incongruent with what the Language in Education Policy requires. Even other documents which support the Language in Education Policy like the school language policies, were not used as guiding documents for classroom practice. Lastly, this study revealed that, despite a plethora of literature on how practice engages and disengages with Language in Education Policy (LiEP), the deconstruction of colonial and apartheid education is still a challenge especially in language use, perceptions of mother tongue instruction and the hegemony of English. One of the recommendations of this study is that teachers must be taught to use Languages of Learning and teaching required in their areas and they should also be given continuous professional development courses on policies so as to improve their practice. Language Policy Units should be set up within the provincial and district Departments of Education that would support the implementation of LiEP. , Thesis (MEd) -- Faculty of Education, Education, 2021

- Description: The Equal Weight View is a frequently discussed position in the philosophy of disagreement. It holds that when someone disagrees with an epistemic peer, they should adjust their belief to be closer to their peer’s belief. While the reasons for adopting this response to disagreement have been debated, there has been less discussion about its utility as a tool for handling real-world disagreements. In this thesis I pursue a version of the Equal Weight View which is useful in practice. I argue that traditional applications of the Equal Weight View do not reflect its underlying principles when they are used to resolve real-world disagreements. I develop an idealized application of the Equal Weight View that addresses the problems traditional applications face in real-world scenarios. Unfortunately, addressing these problems results in an application that is unrealistically cognitively demanding. The application trades being insensitive to the environment it would be used in for being insensitive to the limits of its user. I suggest that we might be able to save the idealized application and work around those limits by either externalizing or simplifying the most demanding aspects of the application. Externalization is best achieved by making use of some kind of computer assistance. Simplification involves replacing taxing data tracking and computation with heuristic methods. While neither approach is ideal, I argue that both get us closer to resolving disagreements in accordance with the underlying principles of the Equal Weight View than traditional applications do. , Thesis (MA) -- Faculty of Humanities, Philosophy, 2021

- Description: This study examines the everyday conceptions and navigations of citizenship by Xhosa widows. It examines widows’ own understandings and experiences of citizenship once the official mourning period, known amongst amaXhosa as ukuzila, has ended. The study draws from 14 interviews with Xhosa widows from the Amalinda, Tsholomnqa, Mdantsane, Magcumeni, KwaNonkcampa, and Dimbaza areas in the Eastern Cape, South Africa. This thesis contextualises claims to widowhood in the context of democratic South Africa, and the various ways in which widowed women conceptualise their lives after ukuzila. While ukuzila itself is written about in the literature, the contentious claims to widowhood and the ways in which women come to make sense of their lives in the post-mourning period remains largely unexplored. Interviews were conducted with women who had undertaken customary and/or civil marriages, had divorced or separated from their partners, or had cohabited. They reveal that widowhood is tenuous and as such, remains contested and contestable. The study demonstrates that much of the claims to widowhood are made because of the undeniable labour that women perform during the partnerships, where they are the primary economic providers. The study shows that whether in the formal and informal sector, women have been central in building the economic livelihoods of their families. In the post-mourning period, the theme of ukuhlala (to stay) that is articulated by widows, shows that they choose to remain in their marital homes to protect what they have laboured for. The findings demonstrate that the key to ‘good’ widowhood is intricately linked to ‘good’ motherhood. For Xhosa widows, much of their decision-making, and livelihood strategies, rests on how they craft good livelihoods for their families. These include a negotiation of feminist economies with woman-centred networks, a reliance on spirituality, as well as negotiations for dignity and respect within the homestead through the protection and maintenance of what they have built over the years. , Thesis (MA) -- Faculty of Humanities, Political and International Studies, 2021
