- Description: Traditional centralised energy systems are coming under increasing pressure because of decarbonisation, decentralisation, and digitisation. A lack of energy security and the inability to manage bi-directional electricity flows constitute two of the biggest challenges faced by centralised systems. Furthermore, in South Africa, the country’s energy system remains monopolised with one large utility satisfying most of the country’s electricity demand. This study is motivated by the need to address energy security within such a monopolised market. To redress the problems highlighted above, this study explores how blockchain and microgrid technology can be integrated to enable decentralised energy production and trading in South Africa. As such, this study develops a fully integrated blockchain-based microgrid energy trading system model. The functional requirements of the system are presented in the form of a business process model. Amongst other benefits, an active blockchain-based microgrid energy trading system provides a means to bolster energy security for the systems’ users. A unique aspect of this study’s approach to energy trading is the utilisation of blockchain’s native tokenizing capabilities. Prosumer energy tokens are minted to create a digital currency for local peer-to-peer energy exchange. A commons-rule based approach is adopted for governing energy resources. As such, this study demonstrates that commons-based solutions provide a feasible alternative to market and profit driven trading for organizing local energy exchange. The primary deliverable of this study satisfies the request of various blockchain researchers for blockchain research to focus on holistic conceptualisations, rather than on the minutiae of blockchain technicalities. Eight core functional requirements of a blockchain energy trading system were identified prior to the construction of the process model. The functional requirements were elicited during a scoping review as a part of the secondary data collection process. Expert review was utilised to verify the functional requirements of the blockchain energy trading system. Once the experts were identified, each expert completed a questionnaire with the intention to verify the requirements. The above process constituted the expert review process for the study. Additionally, the syntactic correctness of the business process model was verified by a business process modelling expert. Weber’s Theory of Evaluation constitutes the theoretical underpinning for the evaluation of the system parts. This study contributes the first publicly accessible business process models of a blockchain-based microgrid energy trading system. This study seeks to advance the discussion of a more integrative and cross disciplinary approach concerning blockchain research, particularly as it pertains to microgrid energy trading. , Thesis (MCom) -- Faculty of Commerce, Department of Information Systems, 2022

- Description: Households consume up to 20% of total global electricity consumption, hence they are important role players in efforts for promoting sustainable consumption. Research on electricity-use behaviour and effectiveness of interventions is important for informing intervention strategies. However, relative to developed countries, research on this subject is lacking in developing countries, where electricity access is limited, and a substantial proportion of households are energy poor. The main goal of this study was to examine reported electricity-use behaviour and the effects of co-designed interventions on household electricity consumption in low-income households in Makhanda, South Africa, using a field-based experiment. Findings from self-reported electricity-use practices showed mixed results, with households reporting both good electricity-use behaviour (e.g., cooling down hot food before refrigeration) and wasteful actions (e.g., leaving appliances on standby). Results showed that electricity-use behaviour was influenced by socio-psychological values including universalism, benevolence, hedonism, and power. Over the intervention period, households exposed to co-designed electricity-saving interventions showed mean electricity savings of about 5.5%, while households in the Partial Treatment and Control group showed increased electricity consumption. Socio-demographic factors such as age and psychological factors (involvement and perceived behavioural control) were very important determinants of household consumption. Broadly, the findings empirically validate the impact of collective problem formulation and co-designing interventions in promoting sustainable actions. , Thesis (MSc) -- Faculty of Science, Environmental Science, 2022

- Description: Organisations face major challenges to address the exploitation of non-renewable resources and consider management considerations for dealing with climate change. Organisations have been pushed to play a part in their carbon footprints and in curbing climate change. Among these organisations are tertiary institutions that can greatly impact environmental sustainability and address carbon dioxide emissions by embarking on renewable energy technologies. Tertiary institutions play a major role in society by the provision of skilled labour and personnel that are equipped to deal with a range of advancements and challenges. The sustainability of these tertiary institutions has thus been called into question due to the impact they can bring to societies. This research thus aims to identify the motives and barriers to renewable energy adoption in tertiary education institutions. To do this, a literature review was conducted to identify possible motives and barriers to renewable energy adoption. These were then compiled into a questionnaire that was sent to respondents of three different institutions. Respondents were then requested to give feedback on each of the motives and barriers. The respondents were also asked general questions found in literature that addressed the adoption of renewable energy technologies in tertiary institutions. The data was collected using the designed questionnaires. The respondents were able to articulate their perceived barriers and motives to the implementation of renewable energy technologies in tertiary institutions. Data analysis was done using thematic analysis. The results showed that the barriers in the implementation of renewable energy technologies in tertiary institutions were: ‘Cost to Install’, ‘Transition Process’ and ‘Government Policies’. The motives on why educational institutions need to embark on renewable energy projects were found to be ‘Energy Independence’, ‘Cleaner Source of Energy’ and ‘Reduction in Carbon Emissions’. The cost of renewable energy technologies, the process of moving from the Eskom grid, and renewable energy policies that are ambiguous were some factors that were highlighted by respondents on why it is challenging to adopt renewable energies in tertiary institutions. On the other hand, the effects of load shedding currently being experienced in the country and the migration to cleaner sources of energy that cause less harm to the environment, are some of the drivers noted by respondents on why tertiary institutions need to embark on renewable energy technologies. More emphasis needs to be put by stakeholders on tertiary institutions to migrate to cleaner sources of energy, and policies need to be put in place in order to promote institutions to adopt these types of energies. Governments and other role-players need to be visible at all times in addressing energy challenges in tertiary institutions in the wake of the recent load-shedding concerns that have been crippling South Africa. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2022

- Description: Elevated CO2 (eCO2) and rising global temperatures have the potential to alter plant-insect interactions with important implications for plant community structure and function. Previous studies on plant-insect interactions have shown that eCO2 will affect insect feeding guilds differently, impacting negatively, positively or having very little effect. The implications of this on the global invasive plant biological control programme is largely unknown. This study investigates the response of one of the world’s most invasive aquatic plants, Pontederia ( = Eichhornia) crassipes Mart. (Pontederiaceae), to predicted eCO2 conditions of 800 ppm and how this may affect the feeding response of two biological control agents representing different feeding guilds; the leaf chewing Cornops aquaticum Brüner (Orthoptera: Acrididae) and the phloem-feeding Megamelus scutellaris Berg (Hemiptera: Delphacidae). A factorial eCO2 x feeding impact study was conducted at the Rhodes University Elevated CO2 Facility in the Eastern Cape Province of South Africa over 13 weeks in the growing season of 2019. The effect of insect herbivory by C. aquaticum and M. scutellaris at two atmospheric CO2 concentrations, representing current and future predicted concentrations (400 ppm and 800 ppm) on P. crassipes was examined through both biomass and ecophysiological measures. Assimilation rates, C:N ratio, total dry weight and relative growth rate of P. crassipes were unaffected by eCO2 conditions, and plants experienced no CO2 fertilization in eutrophic water conditions representative of South African waterways. Effects of eCO2 on insect herbivory varied depending on the feeding guild. Pontederia crassipes showed compensatory growth responses when exposed to C. aquaticum herbivory regardless of CO2 treatment, but chewing herbivory damage remained constant, and the agent maintained efficacy. Pontederia crassipes showed down-regulation of photosynthesis when exposed to M. scutellaris due to eCO2-related feeding responses by M. scutellaris increasing substantially through a significant (30%) increase in adult population density under eCO2 conditions. These results indicate that the plant-insect interactions that underpin biological control programmes for P. crassipes should remain successful under future CO2 conditions. Phloem-feeding insect damage (M. scutellaris) was significantly greater than chewing damage in this study, suggesting that invasive plant biological control programmes will need to shift focus away from the charismatic chewing insect herbivores and onto the often-neglected phloem-feeding biological control agents due to their overwhelmingly positive response to eCO2. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2022

- Description: Pereskia aculeata Miller (Cactaceae) is a primitive creeping cactus that originated from South America and has become an invasive alien plant in South Africa and Australia. Due to its vine-like growth form mechanical and chemical control are not feasible options for its control, therefore biological control is the best option for controlling this plant. Phenrica guerini (Bechyné) (Chrysomelidae) is a leaf-feeding flea beetle that has been released as a biological control agent against Pe. aculeata in South Africa and has been shown to be damaging at some sites in the country. In this thesis, further studies into the use of Ph. guerini as a biological control agent against Pe. aculeata were conducted to determine whether the beetle should be released as an agent against the target weed in Australia. The host range of a potential biological control agent is important to determine as only monophagous agents, or agents with suitably restricted host ranges, should be considered for release. Host specificity testing was conducted to determine if Ph. guerini was suitably specific for release in Australia. Phenrica guerini larvae only fed and partially developed on three out of 25 test plants, but failed to pupate on any plants besides Pe. aculeata. Adult beetles did not feed on any test plants and only oviposited on one test plant species. Phenrica guerini did not develop on any plant other than the target weed and is therefore suitably host specific for release in Australia. The efficacy of a potential agent is also important to consider as the release of an ineffective agent can reduce the success of a biological control programme. A laboratory based pre-release efficacy assessment was done to determine the impact that Ph. guerini could have on Pe. aculeata. There was a significant difference between the control plants and those with larvae, with an average of 72 (S.E. ± 12.33) less leaves on plants with feeding and the main stem of the plant being 11.1 cm (S.E. ± 7.17) shorter. Although there were no significant differences observed in the number of additional stems, and weights of the different plant parts, this was not a long term study and many of these differences would not have been observed in a short period. Based on the impact observed on the leaves and the main stem, and various field studies that have been done to assess the impact of Ph. guerini on Pe. aculeata in the field in South Africa, Ph. guerini appears to be a potentially damaging agent. As Pe. aculeata is still in its early stages of invasion in Australia the beetle has the potential to be damaging and reduce the invasion trajectory of the plant. This study showed that the beetle is suitably host specific and potentially damaging enough to be recommended for release as a biological control agent against Pe. aculeata in Australia. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2022

- Description: There is a need to promote positive financial behaviour in South Africa. According to the Human Sciences Research Council (2018), South African financial behaviour culture emphasises a financially vulnerable nation in terms of not having enough income for future planning and lacking financial self-control. In its key role in influencing financial behaviour, financial socialisation, which is characterised by interactions with indirect, or purposive financial education and communication of financial norms influencing financial behaviours, attitudes, knowledge, capabilities, and self-efficacy of consumers, is the topic of this study. The purpose of the study was to investigate the influence of financial socialisation agents on financial (actual and self-assessed) knowledge, financial self-efficacy and financial behaviour among South African consumers. Based on Glenn’s (2018) framework, Xiao et al. (2009) socialisation and Moschis et al. (1978) consumer socialisation theory, the financial socialisation theoretical framework is provided for this study. Literature review provided an overview of past studies on the concepts of financial socialisation, financial (actual and self-assessed) knowledge, financial self-efficacy and financial behaviour. Therefore, a positivistic research paradigm was adopted, which used a cross-sectional correlational research methodology. This study analysed data primarily collected by a questionnaire survey of South African social attitudes to financial literacy by the Human Sciences Research Council (2011), using a multi-staged sampling technique in all South African provinces of consumers of 16 years and older. Descriptive statistics showed that most respondents were black African females between the ages of 26 and 35 years. Most held Matric certificates and were in paid employment for 30 hours or more per week. Most respondents considered family to be the most influential financial socialisation agent, followed by friends, then the bank. Actual financial knowledge of respondents, was indicated as relatively high. Results on self-assessed financial knowledge showed that most of the respondents considered their level of financial knowledge to be neutral. Using Pearson product-moment correlations to measure the strength and correlations of relationships, positive significant correlations were found between financial socialisation agents, financial (actual and self-assessed) knowledge and financial self-efficacy, while a negative and insignificant correlation was found between financial socialisation agents and financial behaviour. Multiple regression analysis results testing the hypotheses of the study demonstrated that financial socialisation agents have a significant positive influence on financial (actual and self-assessed) knowledge and financial self-efficacy; a significant influence on financial behaviour was not reported. Self-assessed financial knowledge showed a positive significant influence on financial self-efficacy and actual financial knowledge had an insignificant negative influence on financial self-efficacy. Actual financial knowledge had a significant positive influence on financial behaviour, whereby a positive yet insignificant relationship was found between self-assessed knowledge and financial behaviour. In the end, recommendations for the results indicate that financial educators need to develop a financial education plan that will include other content areas of financial knowledge such as identified by Huston (2010) and Lusardi and Mitchell (2011); the most important recommendation would be to help consumers have an accurate understanding of their own level of financial knowledge and to improve financial self-efficacy in consumers, financial socialisation experiences such as offering encouragement to open a bank account, to save and invest money, and presenting opportunities to practise financial skills, may increase consumers’ self-efficacy and lead to positive financial behaviours. , Thesis (MCom) -- Faculty of Commerce, Management, 2022

Therefore, a positivistic research paradigm was adopted, which used a cross-sectional correlational research methodology. This study analysed data primarily collected by a questionnaire survey of South African social attitudes to financial literacy by the Human Sciences Research Council (2011), using a multi-staged sampling technique in all South African provinces of consumers of 16 years and older. Descriptive statistics showed that most respondents were black African females between the ages of 26 and 35 years. Most held Matric certificates and were in paid employment for 30 hours or more per week. Most respondents considered family to be the most influential financial socialisation agent, followed by friends, then the bank. Actual financial knowledge of respondents, was indicated as relatively high. Results on self-assessed financial knowledge showed that most of the respondents considered their level of financial knowledge to be neutral. Using Pearson product-moment correlations to measure the strength and correlations of relationships, positive significant correlations were found between financial socialisation agents, financial (actual and self-assessed) knowledge and financial self-efficacy, while a negative and insignificant correlation was found between financial socialisation agents and financial behaviour. Multiple regression analysis results testing the hypotheses of the study demonstrated that financial socialisation agents have a significant positive influence on financial (actual and self-assessed) knowledge and financial self-efficacy; a significant influence on financial behaviour was not reported. Self-assessed financial knowledge showed a positive significant influence on financial self-efficacy and actual financial knowledge had an insignificant negative influence on financial self-efficacy. Actual financial knowledge had a significant positive influence on financial behaviour, whereby a positive yet insignificant relationship was found between self-assessed knowledge and financial behaviour. In the end, recommendations for the results indicate that financial educators need to develop a financial education plan that will include other content areas of financial knowledge such as identified by Huston (2010) and Lusardi and Mitchell (2011); the most important recommendation would be to help consumers have an accurate understanding of their own level of financial knowledge and to improve financial self-efficacy in consumers, financial socialisation experiences such as offering encouragement to open a bank account, to save and invest money, and presenting opportunities to practise financial skills, may increase consumers’ self-efficacy and lead to positive financial behaviours. , Thesis (MCom) -- Faculty of Commerce, Management, 2022

- Description: Honeybush (Cyclopia spp.) is an endemic legume to the fynbos region of South Africa, and certain species of the genus are used to make health tonics. There are growing international markets for such products and, currently, wild populations of the species Cyclopia intermedia are disproportionately relied upon to support this increase. Due to the sensitivity and ecological complexity of the resource, serious concerns about sustainability and regulation have arisen. The social landscape of the resource is equally as complex, and solutions for alleviating pressure on wild populations, such as reducing or banning harvesting, and switching to commercial cultivation are untenable in every case. A possible option, which has been used in the wildflower industry, is to augment (increase) wild populations by planting seeds or seedlings directly into the veld. The main focus of this research was to explore the viability of using augmentation to boost wild populations of C. intermedia through field trials. In support of this broad aim, research objectives addressed understanding the ecological habitat conditions of the species, quantifying the economic potential of augmentation, characterizing wild populations and conducting seed germination tests. GIS methods were used to locate sites most representative of natural conditions on different post-fire aged veld on a farm in the Kouga mountains. The study characterized habitat conditions by collecting soil and vegetation samples at plots where honeybush was present and absent within close proximity. Vegetation diversity was only slightly higher in presence plots, and no clear pattern between absence and presence plots was observed for soil properties. However, post-fire site age did significantly influence certain nutrient levels. The augmentation trial results indicate that seedlings have a much higher survival rate than seeds on average. Survival success varied unpredictably between plots where wild honeybush was already present and adjacent plots where it was absent. Post-fire site age influenced seedling growth and seed survival positively with the newly burnt plots showing the best growth rates overall. The cost-benefit analysis reveals that seeds are a better option as they require low-cost inputs and carry less risk, unlike seedlings which may have higher survival but are more expensive. The study recommends using trials to assess survival before choosing an option. Out of five natural populations of honeybush that were assessed only one showed seedling recruitment and three young plants were found between two of the other sites. Growth characteristics of populations showed expected variability based on site conditions and disturbance history. Growth appears to be rapid in the first-year post disturbance, thereafter slowing down. Average stem numbers and basal circumference increased concurrently for both harvested and unharvested populations. Due to the influence of natural conditions such as slope aspect and soil properties on plant morphology, it is best to compare harvested and unharvested individuals from the same site and preferably within close proximity to minimize such differences. Using seed sourced from the same parent population is critical to preserving genetic integrity and little is understood about germination characteristics from wild C. intermedia populations. The study tested germination rates between green and brown seed and alternative collection methods. When comparisons were done within farms on two occasions collection and seed colour did have a significant influence. Overall, the influence of which farm the seeds were collected from appeared to play the biggest role in determining germination. , Thesis (MSc) -- Faculty of Science, Geography, 2022

I am motivated by writers who use what I would term reflective expressionism to evoke empathy by tapping into innate, universal emotions. In particular Tiff Holland’s vivid telling of family in the novella Betty Superman where she navigates complex relationships, and bell hooks’ memoirs Bone Black: Memories of Girlhood written as poetic vignettes in fluctuating points of view to draw attention to the intricacies of social structures. Joanna Walsh’s Vertigo has strongly influenced my approach to writing through her compelling imagery and use of motif in fragmented prose that delves into the psyche of her characters. I am also inspired by Lidia Yuknavitch’s visceral use of language, identifying with her invitation: “You deserve to sit at the table.

- Description: Deteriorating environmental water quality is one of the complex challenges in South Africa that threaten freshwater ecosystem health and functionality. An emerging concern is the contestation of water quality regulatory instruments such as standards in water use licences (WUL), and the resource quality objectives. In the Vaal Barrage catchment where this study was undertaken these contestations were evident, suggesting the need for both technical and social solutions to water quality changes in socio-ecological systems. The Vaal Barrage catchment within the lower section of the Upper Vaal is a highly developed, urbanised, and complex catchment supporting and contributing to the social-economic development of Gauteng Province and the entire country, as the Upper Vaal contribute 20% to the Gross Domestic Product of South Africa. This study explores the motivations for stakeholders’ contestations of water quality regulatory instruments in order to contribute to ways in which water resource users and regulators can collaboratively address water quality challenges in the Vaal Barrage catchment. The study also explores water quality scenarios and their ecological and management implications. Document analysis, participant observations and a semi-structured questionnaire were deployed to explore stakeholders’ motivations, values, and perceptions of the water quality regulatory instruments. The results were triangulated to gain better insights into research participants responses. To explore water quality management scenarios, the study applied a water quality systems assessment model Decision Support System (DSS). The DSS was recently developed as part of a bigger project within the Vaal Barrage catchment. Regarding stakeholders’ motivation for contesting water quality regulatory instruments in the catchment, the results revealed a perceived lack of scientific credibility and defensibility in the processes used for deriving standards in WUL, a lack of transparent linkage between the WUL and resource quality objectives, and the increased need for stakeholder engagement in the resource quality objective formulation process. Furthermore, the study revealed punitive measures, education and awareness, self-regulation as mechanisms to encourage compliance. The applied DSS results showed that high nutrient loads, sulphate and total dissolved solids sourced from upstream catchments contribute to water quality deterioration in the Vaal Barrage catchment. The results also showed that the Vaal Barrage catchment could not host additional licence emitters because of TDS, phosphate and nitrate levels, which pose a serious risk to the ecology of the Vaal Barrage catchment, indicating that system had exceeded its assimilative capacity for critical water quality variables. Lastly, the results evidenced the need for collaborative action by the waste emitters within the Vaal Barrage catchment, particularly collaboration between upstream and downstream waste emitters. The study has far-reaching implications for water quality management in South Africa. These include i) the need for transparent and open processes and methods for deriving standards in water use licence, ii) the need for a water quality DSS that recognises catchment hydrological complexity in deriving standards in WUL, and for linking WUL and Resource Quality Objectives (RQOs), iii) collaboration between resources users, and between the resources users and the regulators to bring pollution to acceptable levels and iv) both social and technical solutions are necessary for managing water quality challenge, particularly in a highly developed catchment such as the Vaal Barrage system. , Thesis (MSc) -- Faculty of Science, Institute for Water Research, 2022

- Description: This study investigated the extent to which gays and lesbians access quality sexual and reproductive health (SRH) services in Pretoria and Bulawayo. The study also examines the facilitators and barriers for accessing the same services. Theoretically, the study was grounded in the Health Belief Model (Hochbaum, 1958, modified by Rosenstock, 1974 and Siddiqui, 2016). To answer the research questions, a mixed methods approach was applied involving both qualitative and quantitative data collection methods. A total of 30 key informant interviews, eight focus group discussions and 387 questionnaires were administered using purposive, time location and snowball sampling approaches in the two cities. The study found that the most commonly available sexual and reproductive health (SRH) services were contraceptive services, sexually transmitted infections (STI) services and Human immunodeficiency syndrome (HIV) services. The services were provided at public health facilities, drop-in centres and through outreach activities operated by Civil Society Organizations (CSOs). The least available services that gays and lesbians required as part of a comprehensive package were access to information, education and communications (IEC) materials and mental health and psychosocial support services (MHPSS). Several service providers were not adhering to the World Health Organization (WHO) guidelines for provision of comprehensive services for key populations including gays and lesbians. Critical gaps noted included the absence of key populations-only service hours, lack of options for clinicians to attend to them, presence of a stigma and discrimination free environment and provision of comprehensive package of services under one roof. Most of the referral facilities had limited drugs, equipment and supplies for cancer screening and they had no HIV prevention, sex change, in-vitro fertilization, and sterilization services and procedures. The quality of physical facilities and SRH services in both cities did not meet the expectations of gays and lesbians, acting as a barrier to their health seeking behaviour. Stigma and discrimination from healthcare workers was a huge barrier affecting access across all public health facilities. The acts of stigmatisation and discrimination affected the perceptions that gays and lesbians had regarding the quality of the services and compromised access of the same. In view of these health system challenges, the study recommends that there is need for public authorities in both cities to address the bottlenecks and barriers affecting access to SRH services and products such as lubricants, affordable quality condoms, dental dams and latex gloves while reinforcing the facilitating factors promoting access. Healthcare workers need further training on how to provide comprehensive services for gays and lesbians according to the WHO guidelines. Public health authorities in Bulawayo and Pretoria should build upon the identified factors which facilitated the access to SRH services and use of products such as condoms and lubricants. These factors require strengthening of community-based organizations and networks that work directly with gays and lesbians in both Bulawayo and Pretoria. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2021

- Description: Most developing countries in the African continent, including South Africa, seem to be lagging behind in research, policy development, and how to prevent cybersecurity threats. These findings are evident in the significant number of cyberattacks recorded in the Cost of Data Breach Study and Global Analysis by Ponemon Institute. Research studies are placing the blame on the element of portability in electronic health records (EHRs) that has contributed to numerous vulnerabilities to hospital healthcare data. As a result, the healthcare information of patients in those hospitals that are equipped with interconnected medical devices is exposed to cybersecurity threats. The purpose of the study was to develop a healthcare contingency management framework that can be used by healthcare institutions to mitigate cybersecurity threats to EHRs in the public health sector in South Africa. The integrated systems theory (IST) which amalgamated five different theories relating to information security management was used as a theoretical foundation in this study. In achieving this purpose, the literature review was selected as the research design best suited to answer the question presented in this research study. An expert review was used to refine the framework outcome using interviews and questionnaires. The contribution that will be made by this study will be in a form of a conceptual framework that will be used to mitigate cybersecurity threats concerning EHRs in the public health sector. The healthcare contingency management framework (HCMF) can be adopted by either the National Health Department or Provincial Health Department to be used by healthcare facilities as a guide in reviewing their support function, process management, governance management, and their contingency management. Similar future studies need to be conducted on large scale such as in the whole public sector with the focus on the health sector. , Thesis (MA) -- Faculty of Management and Commerce, 2021

- Description: While research shows that the recognition and integration of indigenous knowledge (IK) is an important issue for developing culturally responsive strategies when teaching and learning science to, and by, indigenous people, little has been said about cultural taboos of a sexual nature and their effects on teaching and learning. This study investigated issues of taboo language use when teaching topics of a sexual nature during high school Biology classes. It also investigated the effects of a teacher development intervention based on Ogunniyi’s Contiguity Argumentation Theory (CATPD) towards culturally responsive teaching strategies. Four phases in one cycle of a Critical Participatory Action Learning and Action Research (CPALAR) design were used in schools located in deep rural villages with a sample of Life Science Grade 12 teachers. Initially, 30 teachers answered a semi-structured questionnaire aimed at identifying cultural restrictions that could impede the teaching of sexual concepts (Stage 1). Stages 2-4 included seven participants of both gender. Data were generated from two sets of drawings with descriptions and audio recorded focus group discussions. The teaching of a collectively developed Indigenised Teaching Strategy lesson by a group-selected ‘modelteacher’ was video-recorded and analysed. Written participant evaluation is presented in a flow chart. Data analysis was done by manual thematic data analysis and by using Atlas ti. 8. The use of multiple data collection strategies contributed to the trustworthiness and credibility of the study. The few existing studies on cultural taboos report avoidance of using the vernacular for biological terminology and promote the exclusive use of standard, terms in English. In contrast, Xhosa IK-based sexual euphemisms derived from elderly, unlearned Xhosa women were successfully used for teaching sexual concepts. The teachers reported their findings through the cultural lens of Xhosa people. Cognitive change from the suppressed level in the CAT hierarchy to a more harmonious equipollent level of understanding was brought about using Bakhtin’s theory of heteroglossia and the indigenist cognitive perspective of Contiguity Argumentation Theory. This cognitive shift enabled verbalisation of the culturally avoided taboo sexual concepts. The transition in thinking symbolised transformation in terms of critical pedagogy. The claim is made that using Contiguity Argumentation Theory (CAT) and Bakhtin’s explanations of heteroglossia provides an effective professional intervention in a deeply culturally determined Xhosa community. While not generalisable, the effect of this strategy should be of value when considering teacher development in indigenous communities and disciplines. , Thesis (PhD) -- Faculty of Education, 2021

- Description: While research shows that the recognition and integration of indigenous knowledge (IK) is an important issue for developing culturally responsive strategies when teaching and learning science to, and by, indigenous people, little has been said about cultural taboos of a sexual nature and their effects on teaching and learning. This study investigated issues of taboo language use when teaching topics of a sexual nature during high school Biology classes. It also investigated the effects of a teacher development intervention based on Ogunniyi’s Contiguity Argumentation Theory (CATPD) towards culturally responsive teaching strategies. Four phases in one cycle of a Critical Participatory Action Learning and Action Research (CPALAR) design were used in schools located in deep rural villages with a sample of Life Science Grade 12 teachers. Initially, 30 teachers answered a semi-structured questionnaire aimed at identifying cultural restrictions that could impede the teaching of sexual concepts (Stage 1). Stages 2-4 included seven participants of both gender. Data were generated from two sets of drawings with descriptions and audio recorded focus group discussions. The teaching of a collectively developed Indigenised Teaching Strategy lesson by a group-selected ‘modelteacher’ was video-recorded and analysed. Written participant evaluation is presented in a flow chart. Data analysis was done by manual thematic data analysis and by using Atlas ti. 8. The use of multiple data collection strategies contributed to the trustworthiness and credibility of the study. The few existing studies on cultural taboos report avoidance of using the vernacular for biological terminology and promote the exclusive use of standard, terms in English. In contrast, Xhosa IK-based sexual euphemisms derived from elderly, unlearned Xhosa women were successfully used for teaching sexual concepts. The teachers reported their findings through the cultural lens of Xhosa people. Cognitive change from the suppressed level in the CAT hierarchy to a more harmonious equipollent level of understanding was brought about using Bakhtin’s theory of heteroglossia and the indigenist cognitive perspective of Contiguity Argumentation Theory. This cognitive shift enabled verbalisation of the culturally avoided taboo sexual concepts. The transition in thinking symbolised transformation in terms of critical pedagogy. The claim is made that using Contiguity Argumentation Theory (CAT) and Bakhtin’s explanations of heteroglossia provides an effective professional intervention in a deeply culturally determined Xhosa community. While not generalisable, the effect of this strategy should be of value when considering teacher development in indigenous communities and disciplines. , Thesis (PhD) -- Faculty of Education, 2021

- Description: It is the norm that job creation becomes the responsibility of entrepreneurs in the area where they operate. The role of the state is legislatively to create a conducive environment for the entrepreneurs to flourish and do their respective businesses in a manner that is beneficial to themselves and the society at large. This study was conducted in Chris Hani District municipality. The district consists of six Local Municipalities where it coordinates their activities and renders support where necessary. Over the past few years, the district has been inundated with requests for financial support from SMMEs. In this regard the researcher undertook to do a follow up in the form of this study to the extent in which the SMMEs contribute to job creation in the district. The study undertook both a qualitative and quantitative approach in ensuring they complement one another and to allow effective engagements with the SMMEs as the core of the study. The sampled respondents/participants in the study were given questionnaires to respond to that would assist the researcher in analysing the raw data and be able to arrive at a particular conclusion in relation to the research questions. Respondents were given an opportunity to respond to questionnaires for a period of two weeks at the comfort of their homes. The results of the study indicate that those firms with a good track record, high annual turnover, sophistication and diverse skills, good credit record, good cash flow, proper financial records, bankable and viable business plans, collateral and registered for VAT were more likely to have a higher impact on the creation of both the short- and long-term employment as they are in a more sustainable position. The conclusion of the study is that the internal factors turned to have the greatest influence on SMME sustainability and job creation in this regard. However, there is more to be done by the private and public SMME support agencies. The study recommends that in-depth empirical research be conducted on the support services provided by private and public SMME support agencies in terms of the services that they offer and the effectiveness of the services and how these are communicated to potential customers. It is also recommended that training workshops aimed at addressing the internal constraints identified be conducted. It is further recommended that the development and implementation of sector-specific mentoring programmes for the owner-managers of the SMMEs be implemented for them to positively contribute to job creation in the region. Strategies to improve the awareness of support services provided by SMME support agencies need to be developed. This would ensure the effective use of these services by SMMEs. It is also recommended that SMME support agencies staff be trained in order to better understand and be more responsive to the owner managers’ needs. , Thesis (MADS) -- Faculty of Business and Economic Sciences, 2021

- Description: Background Medical equipment assumes a major part in diagnosis, prevention and treatment of diseases as well as illness and rehabilitation of patients. The maintenance of medical equipment is one of the most vital components in quality health care service delivery and it should not be ignored in the hospital. Therefore, it is critical that medical equipment must be maintained, and be in good working condition to ensure it completes its life cycle, also to prevent possible injuries to the patients and clinicians/end-users. Proper maintenance of medical equipment needs compliance with the manufacturer’s recommendations. Inappropriate maintenance of medical equipment leads to medical equipment malfunctioning, decreases the level of medical equipment performance, and wastes money and other resources. The equipment downtime makes health care services not accessible to patients. Maintenance includes the following activities, medical equipment acceptance, preventive maintenance, inspection, calibration and repair following the manufacturer’s recommendations. Aim of the study The purpose of the study was to assess compliance to the maintenance procedures of medical equipment in a selected hospital in Oliver Reginald Tambo District, Eastern Cape Province. Methodology A qualitative descriptive design was used to access information regarding compliance with the maintenance of medical equipment in a selected hospital, in Oliver Reginald Tambo District, Eastern Cape. The compliance was accessed at the selected hospital that has eight departments. The research objectives gave a framework for how the research was to be conducted. The data was collected through semi-structured interviews until data saturation. An open coding Tesch’s qualitative method was used for data analysis. A purposive sampling technique was used to select participants who were knowledgeable and responsible for management of medical equipment maintenance. The participants were experienced clinicians and technicians answerable for medical equipment maintenance and management. The researcher adhered to ethical and trustworthiness principles. Findings The following themes and their related categories emerged as compliance procedures adhered to/applied: i) Determinants of applied procedures; ii) Compliance with maintenance that is facilitate frequent checks, daily regular testing of equipment; iii) Report faulty equipment; iv) Send equipment for repairs; v) Do follow up on repairs; and vi) Keep machines working all the time. Contributory factors to non-compliance included: Unavailability of funds; technical staff shortage; lack of technical training; non-compliance in performance of quality checks; lack of training of end users; lack of set of maintenance plans; and long procurement process. Complications aligned with non-compliance: Inappropriate referral patients; inaccessibility of health care services; and misdiagnosing patients. Recommendations The strengthening of clinical engineering department with human resources (technical staff), finance (funds for spare parts) and physical resources (workspace, testing equipment and tools, service manuals etc.) Prioritise medical equipment maintenance also improvement of maintenance budget allocation and utilization. Provision of training for end users and technical staff. Establishment and implementation of maintenance plan and improvement of procurement processes. Conclusion The selected hospital is partially compliant with the maintenance of medical equipment because the hospital performs only reactive maintenance. It evidently appeared that affected service delivery is initiated by the shortage of technical staff and equipment availability and reliability. The hospital needs to focus and improve on the above mentioned factors affecting medical equipment maintenance. The results showed that improper maintenance of medical equipment contributes to the overcrowding of tertiary hospitals through unnecessary referrals due to medical equipment malfunctioning. The study contributes to improving the maintenance management of medical equipment. , Thesis (MPH) -- Faculty of Health Sciences, 2021

- Description: An automotive manufacturer can generate big data through accessible data points from internal and external Internet of Things (IoT) data sources connected to the production line. Big data analytics needs to be applied to these large and complex datasets to realise the associated opportunities, such as an improved manufacturing process, optimised supply chain management, competitive advantage and business growth. In order to store, manage and process the data, automotive manufacturers are using Apache Hadoop technology. Apache Hadoop is a cost-effective, scalable, and fault-tolerant technology. However, there has been a concern raised regarding the privacy of big data in Apache Hadoop. A key challenge in Hadoop technology is its ineffective security model, making the data susceptible to unauthorised users. Consequently, a breach in data privacy results in automotive manufacturers becoming victims of theft of trade secrets and intellectual property via corporate spies. This theft has a negative impact and results in the loss of company reputation, business competitiveness and business growth in the automotive market. This study investigated a solution to ensure big data privacy when using Hadoop technology. The Selective Organisational Information Privacy and Security Violations Model (SOIPSVM) and the Capability Maturity Model (CMM) provided the theoretical base for this study. The researcher undertook a literature analysis and qualitative study to understand and address the identified research problem. The primary data was collected from ten Information Technology (IT) specialists at a local automotive manufacturer. These specialists participated in an interview session, which also included the completion of a questionnaire. All questions were pre-determined and open-ended, and the participants' responses were recorded. Primary data was analysed using the inductive approach by identifying relevant themes and sub-themes. In contrast, the literature analysis included academic journals, conference proceedings, websites, and books, which were critically discussed in this study. This study's findings indicated various measures to be implemented by the automotive manufacturer to address the research problem. Critical success factors were derived from the identified measures, which addressed significant data privacy issues in using Hadoop technology. The identified critical success factors included: control of internal and external data sources; monitor the value of big data towards improving the automotive manufacturing process and user behaviour; implementation of user authentication; encryption to secure data; disaster recovery and backup plan; execution of authorisation and Access Control List (ACLS); conduct audits and regular reviews of user access to data; apply data masking to sensitive data and tokenization to secure data; build own infrastructure to store and analyse data; install regular security updates and update passwords regularly. Each factor had a purpose that examined big data management, governance and compliance in detail. The identified factors contributed towards ensuring data privacy in the use of Hadoop technology. These factors were categorised into contextual and rule and regulatory conditions adopted from the SOIPSVM. Identified conditions were then aligned to the five-level CMM. Each condition was expanded upon at various maturity levels to form a framework that addressed the main research problem. The framework's application was described as an independent assessment of each critical success factor and provided a guide through various maturity levels. The framework's purpose was to address and overcome big data privacy concerns in using Hadoop technology at a local automotive manufacturer. , Thesis (MCom) (Information Systems) -- University of Fort Hare, 2021

- Description: A cynical eviction is an unlawful eviction where, in the course of the eviction, the evictee's home is destroyed. They are a notorious brand of eviction which has darkly coloured South Africa's history and social geography. And they persist still to this day. The cynicality of a cynical eviction lies in the fact that because the home, and its composite materials, are destroyed, application of the mandament van spolie is precluded. With the obvious remedy barred, there is academic and judicial disagreement about which remedy should be used instead. Some have argued that, despite the technical difficulties, the mandament van spolie should be relied on, while others insist that the extraordinary constitutional remedy, crafted in the Tswelopele case, is the best option. This dissertation argues that there are obvious shortcomings with both two remedies, and investigates whether a third remedy, the possessory action, might be better-suited. It finds that, while the possessory action has many benefits, it too is deficient in some respects. It ultimately concludes that all three remedies are only, at best, partially appropriate for addressing cynical evictions and that whichever remedy is the most appropriate in the instant cynical eviction should be preferred for that particular case. , Thesis (LLM) -- Faculty of Law, 2021

- Description: Dentistry offers several caries-preventive measures, some of which emphasise not only patient’s responsibility to manage their disease, but also how dental professionals should manage it. Consequently, this study aimed to examine the knowledge, attitudes, and practices of adult patients towards treatment options relating to dental caries in the geographical context of Buffalo City Metropolitan Municipality, situated in the Eastern Cape Province of South Africa. Purpose Firstly, this quantitative study set out to assess the existing oral health knowledge, attitudes, and practices among an adult population visiting dental health facilities in Buffalo City Metropolitan Municipality, in East London, Eastern Cape, South Africa. Secondly, it aimed to examine the prevalence of dental caries, periodontal diseases and tooth associated diseases in this specific setting. Furthermore, the study sought to provide baseline data in order to organise a successful dental prevention programme. The data obtained will determine the layout of policies to be put forward to the Department of Health. Methodology The researcher took a quantitative approach and conducted descriptive surveys from November 2019 to March 2020. A close-ended, structured questionnaire for data collection was designed based on the aspects of knowledge, attitudes, practices and behaviour pertaining to the area of dental caries. A clinical examination of dental status was performed using dental probes, dental mirrors and tooth air-drying. All decay, and missing, filled or restored teeth due to dental caries, along with the presence of calculus, gingival, and periodontal lesions were recorded. Results Participants had an average knowledge score of 80percent with a 95percent confidence interval of (76percent; 84percent). The majority knew the importance of cleaning their teeth (88.9percent), were aware of the effects of sugary diets (80.7percent), avoided sugary foods (64.6percent), and lastly were aware of the causes of dental caries (71.3percent). However it is concerning that most had never visited a dentist, as reflected by 69.1percent of participants agreeing or strongly agreeing. At least 70percent of those who responded were satisfied with their dentists in that they ( the dentists) freely share ideas and opinions and provide advice on options for dental care. The study revealed a high prevalence of dental caries with a ratio of 6.23. Conclusions The majority of the participants affirmed the importance of visiting the dentist for a routine dental examination. In addition, the majority are aware that sugary diets are associated with dental caries. However, there is a high prevalence of dental caries among participants in this setting. Therefore, dentists should provide preventive measures, along with professional restorative and plaque removal, to curb the burden of dental caries and periodontal diseases. The type and extent of preventive measures must be adjusted according to the patient’s individual needs. Dental health professionals must collaborate with other health-care providers to promote preventive dental health. , Thesis (MPH) -- Faculty of Health Sciences, 2021

- Description: Implanon NXT also referred to as subdermal Implant, is a long-acting subdermal contraceptive method available in the South African public health care system since 2014. The implant was introduced to broaden the choice for women of childbearing age to delay or prevent unwanted pregnancies. Following a surge in popularity, reports of early removals and frequent adverse effects led to a significant decrease in its uptake in the country. Insufficient knowledge on Implanon, poor management of side effects, poor counseling by health care workers, and lack of partner support were the main themes that were picked from the interview, influencing uptake or early removals of the Implanon. The major concerning side effect reported was uncontrolled and irregular heavy bleeding The purpose of the study was to explore the factors associated with low uptake and early removals of Implanon NXT among women of reproductive age in one district in Limpopo province. A qualitative research design was used, primarily as exploratory and descriptive in nature. Participants were identified using non-probable, purposeful voluntary sampling. Data collection was achieved using open-ended structured interviews with sixteen (16) women aged from18-49. Data was analysed using thematic method of organizing data into categories, followed by coding and sorting the data to identify patterns and interpret the meanings and responses. An independent consultant was involved to confirm the thematic areas identified after which consensus discussions took place to finalize the analysed data. From the results, it appeared that there was a need that Implanon should be marketed by use of digital platforms and print media for information sharing. These platforms should be utilized by DOH from the National, provincial, district, facility and community levels. There should be clear protocol on how to manage different kinds of side effects, and this information should be rolled out to the implementation level. Health Care workers should provide client education and counselling services to the clients about the effectiveness of the method. Male partner involvement is crucial to provide support for women on contraceptives and to support their contraceptive choices. Mentorship will help providers to attain their proficiency in Implanon counselling, insertions, and removals. Lastly, availing adequate and effective youth-friendly services to enable young people to open up more about challenges and options that can be explored. For the adolescents and youth, these services should be provided by trained providers not at the general unit, where there is a mixture of adult population and the elderly, but at youth zones to enhance the uptake of Implanon NXT. Recommendations are for clinical practice area, for generic student education as well as for further research. The conclusions confirm that the government need to revitalise the Implanon program, to drive the uptake and reduce early removals. Training of health workers and mentorship should emphasize more comprehensive counselling, provide adequate information on what is to be expected and more importantly, how to treat and manage the side effects. That early removals due to side effects become the last option as information need to be widely available to all users utilising the traditional methods and modern methods such as digital platforms to spread the correct information and create demand for the Implanon. The functional service-provision-based youth-friendly services which will cater for the needs of young women and adolescents is highlighted as it provides a comfortable and conducive environment to provide and receive a comprehensive sexual reproductive health and rights services. , Thesis (MPH) -- Faculty of Health Sciences, 2021

- Description: Implanon NXT also referred to as subdermal Implant, is a long-acting subdermal contraceptive method available in the South African public health care system since 2014. The implant was introduced to broaden the choice for women of childbearing age to delay or prevent unwanted pregnancies. Following a surge in popularity, reports of early removals and frequent adverse effects led to a significant decrease in its uptake in the country. Insufficient knowledge on Implanon, poor management of side effects, poor counseling by health care workers, and lack of partner support were the main themes that were picked from the interview, influencing uptake or early removals of the Implanon. The major concerning side effect reported was uncontrolled and irregular heavy bleeding The purpose of the study was to explore the factors associated with low uptake and early removals of Implanon NXT among women of reproductive age in one district in Limpopo province. A qualitative research design was used, primarily as exploratory and descriptive in nature. Participants were identified using non-probable, purposeful voluntary sampling.

- Description: Walter Sisulu University recruits students from the deep rural areas as well as students from urban areas all over the Eastern Cape Province. Students coming from rural areas are completely different from students coming from urban areas. The difference is caused by the different quality of infrastructure each area is exposed to. Urban students are exposed to high quality education whereas rural students have very poor infrastructure that they can hardly use to better their education. Urban students are exposed to all kinds of mass media and they are taught how to use and manipulate them. For rural students the exposure to mass media is too rare to the point where only the minority is able to use them. Therefore, this research was done to find out if there are any differences in understanding social and current events between urban and rural students studying public relations management at Walter Sisulu University. The study therefore sought to find out if this came as a result of their differentiated exposure to the mass media. Literature collected shows that rural students do not benefit as much as urban students from the knowledge and information communicated by the mass media. This is because rural areas lack electricity for television and radio usage, they lack quality roads for newspapers to be delivered to rural areas. However, questionnaires and interviews show that when at university, rural students struggle to cope in their first year of studies but their performance becomes better in their second and final year of study. , Thesis (MSoc Sci) (Communication) -- University of Fort Hare, 2021

- Description: Parasuicide is a problem that affects the youth locally and globally. Parasuicide has negative psychological impacts on youth. This study was designed to assess elements of parasuicide in the Buffalo City Metropolitan Municipality of South Africa, using records of patients admitted to Frere and Cecilia Makiwane hospitals between 2016 and 2020. The purpose of the study was to conduct a descriptive retrospective review of parasuicide among youth to determine trends, causes, and contributing factors of committing parasuicide. Methods A retrospective, quantitative and descriptive study was conducted with 200 files of patients aged between 18 and 35 years conveniently sampled. These patients diagnosed as committed parasuicide and were admitted at Frere and Cecilia Makiwane hospitals over a period of four years from 1 April 2016 to 31 March 202. Only record files of patients’ residing in East London and Mdantsane catchment area were selected. Raw data was collected for a period of twelve weeks using a developed data collection tool developed in Ms Excel spreadsheet. Results In this sample, the large number of the patients were under 26 years (60.5%), female (57%), single (92.5%), and Black (99.5%). Furthermore, majority of the patients had attained secondary education (89.5%), were unemployed (83%) and living with their families (59%). There were different methods and agents used by participants to commit parasuicide and reasons differed from person to person. Among patients who reported a suicide attempt, organophosphates were most commonly used agent for self-poisoning (47%, n=94), followed by substances such as use of drugs and alcohol (n=57, 28.5%), violence (n=27, 13.5%), corrosive agents including bleach and Jik (n=11, 5.5%), and hydrogen peroxide including acidic sub-stances like battery acid (n=11, 5.5%). The common reason found in the study and indicates participants had psychiatric disorder (34.5%). Conclusion Limiting access to organophosphate agents and other lethal means is an effective strategy that should be adopted to prevent parasuicide among youth. Timely identification of risks or warning signs, social prevention and immediate intervention at the state level will play an important role in controlling parasuicide among youth. Moreover, improving health care services with psychotherapy support would empower youth with skills that would enhance their self-confidence, self-worth and resilience. Consequently, attainment of these attributes would result in the prevention and control of parasuicide amongst youth. , Thesis (MPH) -- Faculty of Health Sciences, 2021
