- Description: This study seeks to interrogate the presentation of women in selected South African texts written by a male and female South African author, whose central thematic thrust is the role of women in their day-to-day struggles during the apartheid era. An in-depth analysis of the texts enables this dissertation to provide a comparative study of the representation of women in both texts. The study also examines the kinds of fictional representations that are found in the texts and their significance in the emancipation journey of women from the supremacy of apartheid and customary laws. This study is informed by African feminism, focusing on the stance of Obioma Nnaemeka and Molara Ogundipe-Leslie. African feminism is chosen as a framework for exploring the texts because it is a theory shaped by the resistance of African women against Western rule. The theory embraces debates about motherhood and the contestation about the roles of motherhood in a society. The theory ponders how motherhood is a source of empowerment, liberation and achievement in African societies. The theory affirms that women should equip themselves for effective resistance and participation in societal transformation. These two theorists are relevant because they are both committed to a critical investigation that seeks to differentiate present social conditions and their historical development. Their research examines the conceptualization of frameworks aimed at a social and cultural change grounded on the local and everyday experiences of women. The first chapter provides a broad overview of the study. This chapter highlights the significance of the study in terms of what it can contribute to scholarship on the representation of women in South African texts that reflect on the apartheid era, by analysing them through the lens of African feminism. The second chapter provides context to the critical reception of both novels, which outlines the focus of the research. This chapter also provides the theoretical framework, which provides an overview of the relevant theory on African Feminism that informs the study and highlights Nnaemeka and Ogundipe-Leslie’s concepts of ‘Nego-Feminism’ and ‘Stiwanism’. The third chapter focuses on analysing the portrayal of women in the texts, examining their interactions with one another, with men, and the subjugation they endure because of living in a patriarchal society. The fourth chapter provides a comparative study of the texts. Finally, the last chapter provides a conclusion, analysing the research findings. The study thus brings to the fore the similarities and differences in the representation of women in South African texts that were written in different decades by a male and female writer, that are nevertheless highlighting the same issues. Secondly, in exploring how women in the texts challenge the status quo, this research will hopefully expose how women are not constantly compliant and embracing marginalization as some texts present them but can be seen as having emancipative agency. The study, in particular, provides an analysis of the representation of women in the two novels, specifically, intending to compare and contrast the modalities of their representation in these works. , Thesis (MA) -- Faculty of Social Sciences and Humanities, 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: 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: Literature has suggested that Malawians are keen to participate. Malawian’s willingness to participate is evident as the country has recorded high voter turnouts during the elections in recent decades. However, literature also suggests that there is minimal citizen engagement in between elections. Elsewhere, Information and Communication Technologies (ICTs) have been used to enhance citizen engagement, but ICT led citizen engagement is still an emerging field and yet to be explored as an area of research particularly in Malawi. We thus sought to explore if the use of ICTs could improve citizen engagement with councils, councilors, and utility companies that provide water and electricity in Malawi. We developed and deployed an ICT platform called Mzinda which means My location in Malawi’s populous Chichewa language. The platform provided various channels for citizens and duty bearers to engage via SMS, USSD, web and a mobile application. We sought to understand the factors that influence citizen’s behavior intention to use an ICT platform to engage. We applied the modified UTAUT model by including Attitude and Self Efficacy social constructs that have among others been cited as limitations of the UTAUT model. We conducted factor loadings of six social constructs of the modified UTAUT model to validate content and reexamine the model in the context of citizen engagement using ICTs in Malawi. We found that, Attitude and Self Efficacy were not significant determinants of the Behaviour Intention for citizens to use the ICT platform. However, 75% of the Behaviour Intention was influenced by Perfomance Expectancy and Effort Expectancy as moderated by age and gender. Empirical evidence showed that responsiveness and actionability of councils and councillors had improved. We also learned that citizens believed that service delivery had improved and that they had more influence over councils, councillors, and the utility companies because of using the ICT platform. We conclude by noting that improvements in service delivery; enhanced responsiveness and actionability of councils, councillors and the utility companies were not necessarily as a result of the ICT platform alone; but a combination of ICTs and non-technology mechanisms of engaging the stakeholders through community campaigns, radio programs, print media engagement, community meetings and debates among others. It is evident that ICTs are not the panacea of all citizen engagement problems. This research can be useful to researchers and practitioners in the technology and citizen engagement domains. , Thesis (MSc) -- Faculty of Science, Department of Computer Science, 2021

- Description: Background: The increased frequency of occurrence and complexity of disasters, the world over, have called for increased cooperation amongst stakeholders to deliver humanitarian aid. Objectives: This study came as a result of the growing interest focussed on creating and implementing cooperation to facilitate management of supply chain-related activities in the humanitarian sector. This study therefore sought to gain a better understanding of the effectiveness of supply chain cooperation in aid delivery performance variables, specifically in the context of Cyclone Idai humanitarian relief operations in Zimbabwe. Method: A pragmatic research paradigm was adopted, where the researchers took a mixed approach informed by both quantitative and qualitative research tools. Results: Findings of this study show a significant and positive impact of humanitarian supply chain (HSC) cooperation in achieving output, resource and flexibility performance in the delivery of aid. These findings will change the shape of humanitarian response to have more cooperation amongst organisations rather than responding as single entities. Conclusion: This study will therefore contribute to how humanitarian organisations improve their approach to future disasters through cooperation in their supply chain activities. Theoretically, the study will show how supply chain cooperation is key to humanitarian responses, thus improving effectiveness of HSC when put into practice. Policymakers can use these findings to develop a standard framework of how humanitarian organisations should collectively respond to disasters. Keywords: cyclone; humanitarian logistics; relief operations; supply chain; supply chain cooperation.

- 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: Health and safety is accepted as an integral element of the built environment. As construction within the electricity and power supply industry is inevitable, alongside other regulatory systems aimed at ensuring sustainable power supply, health and safety measures, policies, training, management, and incidences become important indicators for the delivery of power supply. This research study explores the health and safety management challenges that are experienced by the construction division of Eskom, South Africa’s national power utility with its head offices in Johannesburg, South Africa. The research explores and identifies factors that affect workers’ on-site behaviour regarding the compliance and adherence to health and safety statutory practices. Using a qualitative research method, and thematic data analysis, the research findings draw on salient emerging themes that allude to the inadequate and insufficient documentation of Eskom procedures, and the failure to make use of recorded past incidents in establishing improved pro-active health and safety management practice and management thereof, are but some of the illuminated factors that emerge from the study findings. For a power utility of its scale and the volume of electricity generation, transmission, and distribution, the compliance to internationally recognised health and safety standards within an appropriate legal framework, are factors that may hinder the successful implementation of its core function. Notwithstanding the fact that the electricity sector of industry, in terms of overall current health, safety and performance, is generally considered to be a lower risk than other industries within the South African economy. Yet this study, in taking cognisance of all four sectors of the energy and power value chain (generation, transmission, distribution and retail), attempts to address the unanswered questions if why and how Eskom, despite its health and safety policies and general compliance to statutory workplace health and safety framework, continues to experience a high level of workplace fatalities in the delivery of its projects. Against a backdrop of reported and documented incidences of time, this research found that the usage of reports to benchmark and re-calibrate policy and preventative procedure is carried out periodically, but in an unstructured manner. The risk this presents is evident in the potential failure to identify proper risk analysis, appropriate health and safety vi performance indicators, and a slow migration to the new ISO 45001 quality standard. Study findings also suggest a lack of training programmes for contractors and employees within Eskom construction projects, as a primary contributing hindrance factor to attaining an improved health and safety management system. Finally, the study also considered new hazards and risks that have, and may still, arise from the uptake and expansion of new technologies, cleaner energy, as well as future trends that would collectively influence health and safety standards along the electricity value chain. The research findings suggest for a more focused goal-setting and the building of competencies to recognise and mitigate risks, especially new risks, and to engage more participatory approaches to setting standards that can be effectively managed and which can contribute to injury reduction through behavioural change. What remains to be explored, will be the changing nature of doing business as the year 2020 witnesses a new confounding pandemic, the Coronavirus (covid-19). Its impact on health and safety in the workplace, and on the entire construction value chain, cost of construction, project management and timeframes, is yet to be determined and factored into the business processes of a large scale public entity such as Eskom. , Thesis (MA) -- Faculty of Engineering, the Built Environment, and Technology, 2021

- Description: South Africa is a semi-arid area with an average annual rainfall of approximately 450mm, 60 per cent of which goes towards irrigation. Current irrigation systems generally apply water in a uniform manner across a field, which is both inefficient and can kill the plants. The Internet of Things (IoT), an emerging technology involving the utilization of sensors and actuators to build complex feedback systems, present an opportunity to build a smart irrigation solution. This research project illustrates the development of the field components of a water monitoring system using off the shelf and inexpensive components, exploring at the same time how easy or difficult it would be for a general Computer Science graduate to use hardware components and associated tools within the IoT area. The problem was initially broken down through a classical top-down process, in order to identify the components such as micro-computers, micro- controllers, sensors and network connections, that would be needed to build the solution. I then selected the Raspberry Pi 3, the Arduino Arduino Uno, the MH-Sensor-Series hygrometer, the MQTT messaging protocol, and the ZigBee communication protocol as implemented in the XBee S2C. Once the components were identified, the work followed a bottom-up approach: I studied the components in isolation and relative to each other, through a structured series of experiments, with each experiment addressing a specific component and examining how easy was to use the component. While each experiment allowed the author to acquire and deepen her understanding of each component, and progressively built a more sophisticated prototype, towards the complete solution. I found the vast majority of the identified components and tools to be easy to use, well documented, and most importantly, mature for consumption by our target user, until I encountered the MQTT-SN (MQTT-Sensor Network) implementation, not as mature as the rest. This resulted in us designing and implementing a light-weight, general ZigBee/MQTT gateway, named “yoGa” (Yonella's Gateway) from the author. At the end of the research, I was able to build the field components of a smart irrigation system using the selected tools, including the yoGa gateway, proving practically that a Computer Science graduate from a South African University can become productive in the emerging IoT area. , Thesis (MSc) -- Faculty of Science, Computer Science, 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

- Description: Malaria, cancer and bacterial infections are numbered among the highest causes of fatalities. Most of the drugs used to combat these diseases suffer from resistance, poor absorption and bioavailability and high toxicity. Therefore, delivering a drug requires an excellent drug delivery system that must provide the medication at the site of action in the minimum time possible. Cholesterol is a sterol that is abundantly found in the human body and forms a part in the structure and organization of cell membranes. Many researchers have used cholesterol, especially in organic synthesis, because of its ready availability, low cost and functional groups that can be readily derivatized. In this research, different therapeutic agents (anticancer, antimalarial and antibacterial) were conjugated to cholesterol, and the synthesized compounds were characterized using FTIR, 1H and 13C NMR, Mass Spectroscopy, 2D 1H-13C, HSQC NMR and tested for in vitro biological activity. Thirteen compounds were successfully synthesized. CHS-Cur was the most effective against all Gram-positive bacterial strains, while CHS-Cur, CHS-ZD and C-CAC-ZD were effective against all the bacterial strains. C-CAC-Pyr showed good antiplasmodial activity with 97.75 and 97.83% inhibition at 20 and 10 μg/ml concentrations, respectively. The biological activity of some of the compounds was increased by the conjugation of cholesterol, while others displayed reduced biological activity. In vitro cytotoxicity of the synthesized compounds on HeLa (cervical cancer) cells showed that compounds 2 (7.559 μg/mL), 3 (5.840 μg/mL), 5 (1.44 mg/mL), 7 (4.308 μg/mL) and 11 (3.295 μg/mL) exhibited some good anticancer activity with IC50 values of less than 10 μg/mL. Treating T3T fibroblast cells with compounds 2, 4, 5, 6, and 10 did not reveal a cytotoxic effect on the normal cells when compared to the control, cisplatin. , Thesis (MSc) (Chemistry) -- University of Fort Hare, 2021

- Description: The purpose of the study was to assess multi-grade classroom teaching strategies in rural primary schools at Amatole East Education District. The lens with which to view pedagogical practices of multi-grade teaching was through Bronfenbrenner Ecological System on Human Development and Vygotsky’s Social Learning Theory. An interpretivist paradigm within a qualitative research approach was chosen as befitting the study. The study sampled four primary schools in Amathole East Education District, with eight participants purposively selected. Data collection methods included semi-structured interviews, classroom observations and documents. Data gathering instruments utilised were Interview Schedule, Observation Sheets and Document Checklist. Data was analysed and interpreted through thematic and content analysis. Peer tutoring, self-directed learning and group-work were found to be the most effective teaching strategies in classroom-based teaching. Instructional techniques that involved teacher–directed activities and learner-directed learning activities were viewed as most beneficial for learners in multi-grade settings. However, multi-grade teachers struggled in coping with the utilisation of time and resources in teaching learners of different grade levels combined in the same classroom. The study concludes that during separate grade teaching, grade-by-grade approach, thematic teaching or individual seatwork utilisation of differentiated tasks accommodate application of a variety of teaching strategies. Thus the study suggests that pedagogical practices can be differentiated to address learners’ diverse learning needs, paying more attention to struggling learners. It is further recommended that teachers in multi-grade situations be equipped with special multi-grade teacher training through in-service training programs to overcome challenges of teaching in multi-grade settings. , Thesis (MEd) -- Faculty of Education, 2021
