  • Description: My thesis is a collection of poems and prose that explores the disjunction of losses for women and children across the two languages I inhabit, isiXhosa and English. Ukulahlekelwa lithemba, ukudukelwa yingqondo, ukholo, ubuwena, umzimba nothando. For me, isiXhosa captures the innate musicality and deep emotions within a word or a sound that are not available in English. On the other hand, English readily produces visceral images that are more difficult for me to access in isiXhosa. Kolu phononongo ndikwasebenzisa namagama emboleko ukuze ndikhulise isigama. Ndisebenzisa amagama azibeka zinjalo iimvakalelo, angqalileyo kuncwadi lwesiXhosa. Ndisebenzisa zombini ilyric form kunye neprozi ngenxa yesingqi esiphuhliswa yilyric, nangenxa yenkululeko umbali ayifumanayo kwiprozi. As a bilingual writer ndifuthelwe sisingqi nobunzulu bentlungu obufumaneka in the translated and bilingual works of Isabella Motadinyane, noMarina Ivanovna Tsvetaeva, imibongo yeDaikwan eguqulwe nguStephen Watson ethi Song of the Broken String; iimbongi zespanish ezinjengo Antonia Machado; ngendlela abasebenzisa ngayo ulwimi lwabo ukunabisa nokugqithisa umyalezo ngeentlungu abadibana nazo, bakwanaso nesingqi somculo othuthuzelayo kwimibongo yabo. The structure of my thesis is inspired by the innovative mixed genre layout of Sindiswa Busuku-Mathese’s Loud and Yellow Laughter, and the new formats of isiXhosa writing presented in Mthunzikazi Mbugwana’s poetry. My work has also been shaped by the visceral imagery and briefly captured moments of loss in imisebenzi ka S.S Mema, Nontsizi Mgqwetho, noPascale Petit, novangile gantsho. Imisebenzi yabo ikuzobela umfanekiso ngqondweni ophilayo. Bonke abababhali bahambe indlela endinika umdla nendifuna ukuyihamba nam njengombhali omtsha obhala ngeelwimi ezimbini. , My thesis is a collection of poems and prose that explores the disjunction of losses for women and children across the two languages I inhabit, isiXhosa and English.

  • Description: The South African spearfishery forms a small component of South Africa’s complex coastal fishery. Although the smallest, this fishery sector has the largest proportion of data deficient species, and as a consequence is poorly managed. Oplegnathus conwayi (Cape knifejaw) is an example of one of these species for which there is very little and outdated biological and ecological data. This species is among the top target species by recreational spearfishers in South Africa. This thesis aimed to improve our socio-ecological knowledge of the South African spearfishery through the collection of biological and Fishers’ Ecological Knowledge (FEK) information on Oplegnathus conwayi, and human dimension information on the South African spearfishery. Monthly biological samples were collected through routine sampling (spearfishing) and augmented by recreational spearfishers. A total of 254 fish were collected from the warm-temperate coastal zone (East London – Cape Agulhas), 28 from the sub-tropical zone (Durban – East London) and 23 from the cool-temperate zone (Cape Agulhas – Cape Point). The results indicated that Oplegnathus conwayi is a slow-growing species, with a maximum recorded age of 27 years. The population sex ratio was skewed, with males dominant in the population (1M:0.6F). The length- and age-frequency distributions were, however, similar for both sexes. No significant differences were observed between male and female growth (LRT, p > 0.05), with the overall population growth curve being best described as L(t) = 697.15(1-e-0.06(t-6.30)). Males matured at a slightly larger size than females, however, no significant differences were observed (LRT, p > 0.05). The length- and age- at-50% maturity was 330 mm (FL) and 5.73 years for the full population, respectively. Histological analyses showed that Oplegnathus conwayi are asynchronous spawners with a gonochoristic reproductive style. Macroscopic staging and gonadosomatic index results indicated a protracted spawning season for Oplegnathus conwayi, with a peak in spring. A survey was designed and disseminated to collect FEK on the biology and population status of Oplegnathus conwayi and human dimension information on South Africa’s spearfishery. A total of 103 survey responses were received, of which 94 were regarded as specialised (spearfishers who had greater experience, skill and avidity, and maintained spearfishing as an important component of their lifestyle) spearfishers. Based on the responses of the specialist spearfishers, the top four main species caught by spearfishers from this survey were Seriola lalandi (13.9%), Pachymetopon grande (11.7%), Oplegnathus conwayi (11.4%) and Sparodon durbanensis (11%), and the majority of respondents indicated that there had been no changes in abundance, size and catches of these species in the years that they had been spearfishing. Respondents indicated that Oplegnathus conwayi are most commonly targeted in the Eastern Cape and are found at depths of up to 40 m. Respondents also indicated that there may be a seasonal onshore (Summer/Winter) and offshore (Summer/Winter) migration with year-round spawning and a peak in November, December and January. The incorporation of spearfishers into the data collection, both through the collection of specimens and their FEK, was beneficial to this study. Besides providing samples from a broader geographical range than the primary collection area, the collaboration with spearfishers has promoted the inclusion of this group into the management system. The findings of this study also suggest that FEK data can be more reliable if the concept of recreational specialisation is incorporated into data collection. While the FEK suggested that the population was stable, a stock assessment is necessary to fully understand the population status and implement management strategies. Nevertheless, the key life history characteristics (slow growth and late maturation) observed in this study are characteristic of species that is vulnerable to overexploitation, and thus the precautionary approach should be applied. The reproductive information collected in this study has provided information for the implementation of an appropriate size limit regulation for Oplegnathus conwayi. Here, a minimum size limit of 400 mm TL, which corresponds approximately with the length-at-50% maturity of 330 mm FL, would be appropriate to allow fish to mature and spawn, and reduce the likelihood of recruitment overfishing. Reduction in the bag limit from five to two fish per person per day may also be appropriate as a precautionary measure until a stock assessment has been completed. Finally, the incorporation of stakeholder into biological collection and the use of FEK may be a useful approach for other data deficient species and in countries with limited resources for ecological research. , Thesis (MSc) -- Faculty of Science, Ichthyology and Fisheries Science, 2021

  • Description: This research project constituted as a thesis of limited scope for a Masters in Education Degree (i.e. as 50% of the degree) focusses on a job creation programme named ‘Groen Sebenza’ [Green Work]. Groen Sebenza is an environmental education ‘incubator’ programme driven and implemented by the South African National Biodiversity Institute (SANBI) to unlock green jobs and bridge the gap between education and job opportunities in the biodiversity sector in South Africa. The programme is a key intervention to strengthen biodiversity human capacity development in the biodiversity sector in South Africa, seeking to contribute to transformation of the biodiversity sector, and also address issues of youth unemployment in the country. The young ‘interns’ in the programme were called ‘pioneers’ at the start of the project. This research project explores how a host institution operating as a community of practice within a landscape of practice managed to implement the Groen Sebenza programme by absorbing and appointing all their pioneers into sustainable jobs beyond the pilot project. I sought to better understand the process of supporting and empowering unemployed youth into sustainable green jobs within the Groen Sebenza partnership programme. I drew on Community of Practice (CoP) theory, and its value creation framework to develop this understanding, and I under-laboured the analysis with a social realist analysis of enabling and constraining factors. The unit of analysis of a Community of Practice was a useful focus for the study, as these mentors, managers, and administrators were all involved in supporting the empowerment and retention of the young pioneers in the host institution. To develop deeper insight into the learning and knowing, and value created in and by the Groen Sebenza CoP in the Host Institution, I also sought insight into enabling and constraining factors and how these shaped and contributed to empowerment and retention of the pioneers in sustainable green jobs. The research addressed the main question of ‘How do processes of learning, knowing and value creation contribute to empowerment and retention of unemployed youth in a successful Host Institution in the Groen Sebenza programme, and what enabled or constrained the empowerment and retention processes and outcomes?’. Three sub-questions were used in the study, which focussed on the mentoring, training and workplace experiences and how they contribute to the process of learning and knowing within the Groen Sebenza Community of Practice in the Host Institution? [Addressed in Chapter 4], the value creation elements that emerged in the implementation of the programme in support and empowerment of the pioneers in the Host institution’s Groen Sebenza CoP? [Addressed in Chapter 5], and the enabling and constraining factors that shaped and contributed to the uptake of the Pioneers into sustainable green jobs at the Host Institution within the Groen Sebenza Programme? [Addressed in Chapter 6]. The research was conducted as a qualitative case study, in which I used semi-structured interviews as a key data source, as well as document analysis, and a questionnaire. The study drew on inductive, abductive and retroductive modes of inference since I sought to explore an understanding of the practices and learning that occurred that contributed and led to the successful uptake of Pioneers into jobs, as well as the enabling and constraining factors. The study was interpretive at the epistemic level, and had a social realist under-labouring at the ontological level. Key findings of the study point to the development of enabling cultures of mentoring in workplaces, and the provision of a diversity of workplace learning experiences including formal training. It also points to the importance of personal emergent properties amongst mentors and pioneers that embrace a willingness to work together and build strong relationships, and to learn together. Learning in the community of practice was shown to develop identity and a sense of belonging as pioneers were given meaningful tasks to do and their training and interactions with mentors was experienced as meaningful and relevant. The contributions of the pioneers to the institutional mandate was appreciated by the mentors and therefore also well supported within an empowerment orientation. Various structural factors contributed to this enabling situation, most notably strong support from management as well as good co-operation across divisions. Constraining factors included the physical distances in the province, as well as financial and technical issues such as poor ICT communication systems. Overall, though the study showed that a strong approach to learning in communities of practice supported by empowering mentoring can lead to the integration of young pioneers into sustainable green jobs in the environmental sector. A whole institution approach to this process is, however, needed, and the organisation needs to develop a culture of social learning. As recently as September 2020 as this study was being finalised, the Presidential Employment Stimulus Plan (Office of the President, 2020) following the initial economic shocks emanating from the COVID-19 pandemic, made yet another commitment to using the Groen Sebenza model to create and support sustainable job creation for young people in South Africa today in the environmental sector. This study has been developed and designed to understand those processes and enabling conditions that can support retention and empowerment of young people to take up jobs in the environmental sector today. Its recommendations may therefore be of value to those involved in seeking to support sustainable impacts in terms of retention and employment in programmes such as the Groen Sebenza, and in the Groen Sebenza programme itself as it continues to unfold as a key job creation tool for unemployed youth. , Thesis (MEd) -- Faculty of Education, Education, 2021

  • Description: This thesis interrogates the relationship between the Dispute Settlement Understanding and Africa Continental Free Trade Area dispute settlement mechanism, in light of the conflict of jurisdiction. The conflict of jurisdiction is an adverse effect of the fragmentation of international law. The uncoordinated proliferation of international treaties has increased occurrences of overlapping memberships and overlapping subject matter regulation amongst treaties. Whenever the overlaps mentioned above exist, and a dispute arises concerning matters of overlap, that dispute can be heard in more than one tribunal, giving rise to a conflict of jurisdiction. Jurisdictional conflicts are a problem because they breed uncertainty in the adjudication of disputes; they increase the risk of forum shopping, conflict of rulings, protracted litigation, and waste resources. There is a significant risk for jurisdictional conflicts between the World Trade Organisation and Africa Continental Free Trade Area agreements, because of membership and subject matter overlaps. To mitigate the problems caused by jurisdictional conflicts, the Africa Continental Free Trade Area agreement has incorporated a fork-in-the-road clause. Fork-in-the-road provisions allow parties to choose their preferred forum, and once the forum is chosen, the parties are prohibited from bringing the same dispute to another tribunal. Unfortunately, fork-in-the-road clauses are insufficient in resolving jurisdictional conflicts because they do not bind the Dispute Settlement Understanding. It is only bound to enforce World Trade Organisation obligations and not non-World Trade Organisation obligations. The extent to which non-World Trade Organisation norms apply in the Dispute Settlement Understanding is unsettled, making it difficult to conclude whether a fork-in-the-road provision will be effective an effective solution to potential jurisdictional conflicts. In this thesis, the researcher investigates the prospects of the World Trade Organisation applying the AfCFTA fork-in-the-road clause, directly, as a potential solution to the conflict of jurisdiction. In addition, the researcher will also investigate an alternative means of applying the AfCFTA fork-in-the-road provision, indirectly, using the World Trade Organisation procedural good faith provisions. In conclusion, the researcher provides recommendations on how the World Trade Organisation and the AfCFTA agreement can facilitate the application of fork-in-the-road clauses in the Dispute Settlement Understanding to resolve the conflict of jurisdiction. , Thesis (LLM) -- Faculty of Law, Law, 2021

  • Description: Satoshi Nakamoto, the pseudo-identity accredit with the paper that sparked the implementation of Bitcoin, is famously quoted as remarking, electronically of course, that “If you don’t believe it or don’t get it, I don’t have time to try and convince you, sorry” (Tsapis, 2019, p. 1). What is noticeable, 12 years after the famed Satoshi paper that initiated Bitcoin (Nakamoto, 2008), is that blockchain at the very least has staying power and potentially wide application. A lesser known figure Marc Kenisberg, founder of Bitcoin Chaser which is one of the many companies formed around the Bitcoin ecosystem, summarised it well saying “…Blockchain is the tech - Bitcoin is merely the first mainstream manifestation of its potential” (Tsapis, 2019, p. 1). With blockchain still trying to reach its potential and still maturing on its way towards a mainstream technology the main question that arises for security professionals is how do I ensure we do it securely? This research seeks to address that question by proposing a decision-making model that can be used by a security professional to guide them through ensuring appropriate security for blockchain deployments. This research is certainly not the first attempt at discussing the security of the blockchain and will not be the last, as the technology around blockchain and distributed ledger technology is still rapidly evolving. What this research does try to achieve is not to delve into extremely specific areas of blockchain security, or get bogged down in technical details, but to provide a reference framework that aims to cover all the major areas to be considered. The approach followed was to review the literature regarding blockchain and to identify the main security areas to be addressed. It then proposes a decision-making model and tests the model against a fictitious but relevant real-world example. It concludes with learnings from this research. The reader can be the judge, but the model aims to be a practical valuable resource to be used by any security professional, to navigate the security aspects logically and understandably when being involved in a blockchain deployment. In contrast to the Satoshi quote, this research tries to convince the reader and assist him/her in understanding the security choices related to every blockchain deployment. , Thesis (MSc) -- Faculty of Science, Computer 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: The worldwide popularity of social networking sites (SNSs) and the technical features they offer users have created many opportunities for malicious individuals to exploit the behavioral tendencies of their users via social engineering tactics. The self-representation and social interactions on SNSs encourage users to reveal their personalities in a way which characterises their behaviour. Frequent engagement on SNSs may also reinforce the performance of certain activities, such as sharing and clicking on links, at a “habitual” level on these sites. Subsequently, this may also influence users to overlook phishing posts and messages on SNSs and thus not apply sufficient cognitive effort in their decision-making. As users do not expect phishing threats on these sites, they may become accustomed to behaving in this manner which may consequently put them at risk of such attacks. Using an online survey, primary data was collected from 215 final-year undergraduate students. Employing structural equation modelling techniques, the associations between the Big Five personality traits, habits and information processing were examined with the aim to identify users susceptible to phishing on SNSs. Moreover, other behavioural factors such as social norms, computer self-efficacy and perceived risk were examined in terms of their influence on phishing susceptibility. The results of the analysis revealed the following key findings: 1) users with the personality traits of extraversion, agreeableness and neuroticism are more likely to perform habitual behaviour, while conscientious users are least likely; 2) users who perform certain behaviours out of habit are directly susceptible to phishing attacks; 3) users who behave out of habit are likely to apply a heuristic mode of processing and are therefore more susceptible to phishing attacks on SNSs than those who apply systematic processing; 4) users with higher computer self-efficacy are less susceptible to phishing; and 5) users who are influenced by social norms are at greater risk of phishing. This study makes a contribution to scholarship and to practice, as it is the first empirical study to investigate, in one comprehensive model, the relationship between personality traits, habit and their effect on information processing which may influence susceptibility to phishing on SNSs. The findings of this study may assist organisations in the customisation of an individual anti-phishing training programme to target specific dispositional factors in vulnerable users. By using a similar instrument to the one used in this study, pre-assessments could determine and classify certain risk profiles that make users vulnerable to phishing attacks. , Thesis (PhD) -- Faculty of Commerce, Information Systems, 2021

  • Description: A number of studies have examined the franchisee/franchisor relationship to investigate how to select the correct franchisee and, subsequently, how to maintain a productive franchisee/franchisor relationship. A literature review was therefore conducted on the selection process and the maintenance of the franchisee/ franchisor relationship. The literature suggests that a set of selection criteria to increase the chance of a successful franchisee/franchisor relationship has not been clearly identified. Therefore, this study’s first objectives are: 1) the selection criteria that are used by the franchisor in selecting franchisees. Specifically, how RE/MAX South Africa selects local franchisees; and 2) how the franchisor manages the relationship to ensure compliance by the franchisees who have been selected. For this study, the selection criteria identified by Nevin (1999) and Olm et al. (1988) will serve as the basis of the first part of the study. The four selection criteria categories that have been identified by Nevin (1999) include: financial capability; experience and management skill; demographic characteristics; and attitude towards business. The literature reveals that the viewpoint of the franchisee is often overlooked by researchers, and yet the need of the franchisee should be ascertained to increase the chance of a successful franchisee/franchisor relationship. The literature has indicated that if the franchisors can keep the franchisees satisfied, the opportunity of franchise success and gaining franchisee compliance is much greater. In other words, if a franchisor can attain the correct people and know exactly what they want out of a franchise relationship, this will provide the franchise with a greater chance of success. The third objective of this research is, therefore, to analyse – from the perspective of both franchisees and their franchisor - how the relationship between them is maintained, and ultimately how the franchisor gains compliance from the franchisees. The model of Trust and Compliance (Davies, Lassar, Manolis, Prince and Winsor, 2011), which sets out the relationship between satisfaction, conflict, trust and compliance, was used to examine the franchisee/franchisor relationship. The practices of RE/MAX South Africa served as a case study for this research. Interviews were conducted, with the CEO and five franchisees, to identify the criteria used to select franchisees and gain a holistic understanding of the process of maintaining the relationship. The interview questions were structured using the Davies et al (2011) Model of Trust and Compliance. The data analysis technique that was used to analyse the interviews was thematic analysis. The findings firstly revealed that due to the fluid and low barriers to entry within the real estate industry, RE/MAX as an organisation does not have a standardised set of selection criteria but that an in-house guideline, called the RE/MAX Formula, was vital to this selection process. Secondly, in maintaining the franchisee/franchisor relationship and referring to the four factors of the trust and compliance model (Davies et al., 2011), the following key findings were noted. Firstly, the relationship between satisfaction and trust was primarily based around reciprocation within the franchisee/franchisor relationship. Secondly, various sources of conflict were identified, and it was noted that if conflict was not dealt with adequately, there was a breakdown of trust within the relationship. Finally, the building of trust was based on transparency, accountability, goal congruency and credibility. Recommendations for franchise management and further research were made. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2021

  • Description: Nations in Sub-Saharan Africa tend to experience some of the worst levels of human development and economic freedom in the world. Previous research has shown that there is a positive and significant correlation between these two macroeconomic facets. Further research has shown that if nations' policy-makers can manage their resources and capabilities appropriately, then this could improve their economic freedom and human development levels. This study aims to analyse the relationship between the scores of the 12 different components of the Index of Economic Freedom (IEF) and the overall Human Development Index (HDI) scores of Sub-Saharan African nations. The specific selection of nations utilised in the study are the 16 countries that make up the Southern African Development Community (SADC). Based on a review of the literature on human development, economic freedom, and the Resource Based Theory (RBT) on a macro-level, a correlational study was conducted to determine the relationship between the relevant variables. The information was collected from the Heritage Foundation and the United Nations Development Program (UNDP), respectively. The data and scores collected and used in the study are from the years 2015 to 2019. The correlational results demonstrated that nine of the 12 components of the IEF has a positive and significant correlation with HDI within the selected African nations. The strongest correlation being between 'Property Rights' and HDI. Therefore, it is likely that if the property rights within a nation are upheld, said nation would have higher levels of human development. The three components that proved to have an insignificant result with HDI were; 'Tax Burden', 'Government Spending', and 'Fiscal Health'. The results indicate that all components that fall under the category of 'Government Size' share no significant correlational relationship with human development. It is recommended that governments and policy-makers take this into consideration when managing their resources and capabilities to improve the nation's human development. Further research is required to identify the specifics on how this management and allocation of resources can be utilised effectively to improve the human development and economic freedom in Sub-Saharan Africa. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2021

  • Description: The feasibility of incorporating efavirenz (EFV), an antiretroviral agent against HIV into a lipid-based self-emulsifying drug delivery system (SEDDS) containing vegetable oils was investigated. EFV has poor aqueous solubility and is classified under the Biopharmaceutical Classification System (BCS) as a class II compound with highly permeability, its aqueous solubility is less than 10 mg/ml and is defined as a practically insoluble compound with a consequent poor bioavailability of approximately 40%, and erratic dissolution behaviour. SEDDS formulations have been shown to improve the aqueous solubility and consequently the bioavailability of BCS II compounds such as EFV. EFV is a first line antiviral agent used in combination with other agents in antiretroviral therapy (ART). Among the number of NNRTIs approved for use in HIV treatment, EFV is one of the most commonly prescribed drug. Statistical methods and Design of Experiments (DoE) using Response Surface Methodology (RSM), specifically a Central Composite Design (CCD), were used to facilitate the development of a reversed-phase high performance liquid chromatographic (HPLC) method for the quantitation of EFV during formulation product and process development studies. A rapid, accurate, precise and sensitive HPLC method with ultraviolet (UV) detection was developed, optimised and validated for the in-vitro analysis of EFV in a total run time under 10 minutes for the elution of both EFV and loratidine which was used as the internal standard (IS). The method was then successfully applied to the determination of EFV in commercially available tablets. Excipient screening was undertaken using solubility studies and revealed that EFV had highest solubility in flaxseed oil in comparison to soybean, macadamia, grapeseed, sunflower and olive oils. The non-ionic Tween® 80 and Span® 20 were selected as surfactant and co-surfactant, respectively with ethanol co-solvent as they exhibited improved miscibility with co-solvent. Pre-formulation studies were undertaken to investigate the compatibility of the API with excipients and to identify a nano-emulsion region and other emulsion types using pseudoternary phase diagrams. The phase behaviour of crude cold pressed flaxseed oil with the selected non-ionic surfactants revealed an area within pseudo-ternary phase diagrams for different surfactant-mixtures formed gels/semisolid structures which can be exploited for other drug delivery strategies that require such properties. Fourier transform infrared spectroscopy (FT-IR), powder x-ray diffraction (XRD) and Raman spectroscopy were used to identify and assess the compatibility of EFV with chosen excipients. 2 A reduction in the peak intensity was observed for EFV when combined with each hydrophobic/lipid excipient evaluated revealing that there was a marked reduction in the crystallinity of the EFV. A decrease in crystallinity in comparison with the bulk API may indicate that EFV were amorphous or sequestered in a molecular dispersion and exhibited an increased solubility for the molecule. Flaxseed oil was used as the oil phase in studies for the optimization of surfactant mixtures undertaken using DoE, specifically a D-optimal mixtures design with the flaxseed oil content set at 10% m/m was performed. Solutions from the desired optimization function were produced based on desirability and five nanoemulsion formulations were produced and characterized in terms of in vitro release of efavirenz, drug loading capacity, Zeta Potential, droplet sizes and polydispersity index (PDI). Kinetically stable nanoemulsions containing 10% m/m flaxseed oil were successfully manufactured and assessed. Droplet sizes ranged between 156 and 225 nm, Zeta Potential between −24 and −41 mV and all formulations were found to be monodisperse with polydispersity indices ≤ 0.487. SEDDS formulations of EFV in nano-sized carriers were developed and optimised, in vitro drug release varied with varying amounts of ethanol in the formulation producing formulations that exhibited differently modulated drug in-vitro release profiles that may be further manipulated for better performance and therapeutic outcomes in terms of solubility and possibly bioavailability of EFV when delivered using SEDDS rather than using tablets which in turn may lead to better therapeutic outcomes for patients with HIV. , Thesis (MSc) -- Faculty of Pharmacy, Pharmacy, 2021

  • Description: Appropriate menstrual hygiene management is affected by taboos and secrecy surrounding menstruation. Inadequate information and knowledge about menstruation and lack of resources for managing menstruation hygienically have impacted adolescent girls on a psychosocial and physical level. Consequently, the dignity of schoolgirls during the onset of menstruation through puberty and adolescent phases is jeopardised. It is therefore imperative to understand the normal physiological changes that school-going children from Grades 6 to 12 undergo and acknowledge how these changes affect their education within the school environment. In the Makana district, Eastern Cape, South Africa, the topic of menstrual hygiene management is under-researched at schools and, therefore, this research explores school educators’ perceptions of menstrual hygiene management at primary, secondary and private schools in this area. Schools have a responsibility to create a safe environment for learners’ education, which includes the topic of menstruation without discriminating against or labelling menstruating girls. This research found that the topic of menstruation is only discussed in Life Science and Life Orientation subjects and only covers the physiological changes of the body. These subjects, however, exclude the topic of menstrual hygiene management. This study found that several schools in the Makana district are not adequately equipped to provide for the needs of menstruating girls and therefore educators need to be prepared to deal with menstruation in the school context. The educators are also required to go for regular training or workshops to equip them to manage menstruation in a school environment. The infrastructure of a school includes water and sanitation which are components of menstrual hygiene management. The infrastructure at the participating public schools was inadequate and therefore impacted on the menstrual hygiene management for the girls. The unavailability of water, the non-existence of a sick room and lack of a waste disposal system at some public schools presented further challenges for menstrual hygiene management. A qualitative research method was applied in this study and a symbolic interactionism approach was used. , Thesis (MA) -- Faculty of Humanities, Sociology, 2021

  • Description: This study responded to urbanisation as one of the challenges affecting youths’ lifestyles in this century. Children and youth around the world are living in overpopulated, polluted and unsafe environments which fail to produce opportunities for learning, play and recreation (World Health Organisation [WHO], 2017). This study explored these issues in the context of Makhanda with an intervention to engage youth in sustainability practices, to help them to strengthen sustainable lifestyles. The participants in this research were members of two eco-clubs from two schools in Makhanda ranging in age from 12-14 years (primary school) and 15-17 years (high school). The study explored how learning processes within a club intervention contributed to the well- being of participating youth and their capacity to live sustainable and fulfilling lives. The research explored (with participants) eight themes as matters of concern namely, ‘education’, ‘home-life’, ‘energy use’, ‘mobility’, ‘leisure and communication’, ‘waste’, ‘water’ and ‘food’. Detailed case narratives exploring Wals’ social learning stages were used to explore the themes. These themes were explored through photo narratives of the youths’ lives and matters of concern in sustainability issues, risks and practices emanating from the Makhanda context. The pedagogical framework for the intervention was guided by Wals’ social learning framework for mobilizing sustainability practices. Social learning interaction took place through all the stages of the framework and the challenges and potentials of the educational intervention were explored in relation to each stage. From the six themes suggested above the youth chose food and water as themes to take forward as a response project. The project pursued was a vegetable garden in which the youth were actively engaged in order to seek and try out sustainable ways of living. An interpretive approach was used within the interpretive paradigm. Qualitative data were generated through focus group discussions, observations, individual interviews and document analysis. Practice architectures theory was used analytically to explore the dynamics of the emergent sustainability practices initiated by the eco-club youth. I used it as a change method and a tool for initiating social learning actions for ‘sustainability practices’ projects. The study indicated that the youth’s key challenges affecting sustainability of their lifestyles are: lack of access to basic infrastructure, recreational facilities, electricity supply, transport, security and water. In this study, it was clear that much of the youth’s involvement in these matters of concern and sustainability issues was at the level of participating in the six themes through Wals’ social learning processes. This allowed youths to develop their knowledge and skills on how to participate in the gardening project rather than simply focusing on the environmental matters of concern in question. The Handprint Resource Books have been designed for educators who are looking for practical ideas to work with in the learning areas of the National Curriculum. The focus is on sustainability practices that can be taken up within the perspective that each learning area brings to environment and sustainability concerns. The use of the Handprint Resource Books promoted active youth participation and interaction encouraging youth to be reflective thinkers, which led to understanding of the issues and the sustainability practices that emerged during the discussions. The Handprint Resource Books focused on sustainability practices within the learning area of environment and sustainability concerns. Due to her facilitation skills, an environmental expert’s presentation on a sustainability topic enabled youths to select the intended project. The involvement of youth in the implementation of the vegetable garden as a sustainability practice empowered youth to be more confident in engaging in a collective action for change as they developed the capability to share and start their own vegetable gardens at their homes. , Thesis (MEd) -- Faculty of Education, Environmental Learning Research Centre, 2021

  • Description: University students are at risk for reduced mental wellbeing, particularly during the Covid-19 pandemic, and among the most common problems experienced are academic distress and eating concerns. Through a stress-coping model lens, a link between academic distress and disordered eating in student populations appears possible but has not previously been explored. The present study examines this relationship in a South African undergraduate sample. Data were collected during the Covid-19 pandemic using a cross-sectional, correlational survey design and the Counseling Center Assessment of Psychological Symptoms (CCAPS). The results of a multiple regression analysis indicate that academic distress most strongly predicts eating concerns, followed by the demographic variables of female gender and black racial identification. This novel finding suggests that academic institutions should consider the broader academic environment as point of intervention for the prevention and treatment of disordered eating in students. , Thesis (MA) -- Faculty of Humanities, Psychology, 2021

  • Description: The African wildcat (Felis lybica cafra) is the most common and widely distributed of all wildcats. The southern Kalahari in South Africa offers favourable conditions for African wildcats and supports high wildcat densities on protected and unprotected land. African wildcats have been reported as livestock predators on South African farms, however wildcat-livestock predation is usually reported as infrequent and to have a low financial impact on the farmer. The aim of this study was, firstly, to determine what natural prey species were available for African wildcats on unprotected land and, secondly, to determine the extent of human-wildcat conflict on unprotected land in the southern Kalahari. The frequency of occurrence of potential African wildcat prey was determined through small mammal trapping, camera trap surveys and direct observations. The results indicated that a variety of the African wildcat’s natural prey species occurred on unprotected land and that the dune and adjacent ‘street' habitats most likely supported the majority of small mammals which are preferred prey for African wildcats. The African wildcat’s human-predator conflict status was determined through interview questionnaires (n = 22) with participants who owned or managed farms in the southern Kalahari. African wildcats were perceived to occur on 100% of farms, to be common in the region, to be the top livestock predator on 68% of farms and to be responsible for 46% (n = 1542 newborn lambs) of all livestock deaths in 2020. African wildcats were, however, not viewed in the same negative light as black-backed jackals (Canis mesomelas) and caracals (Caracal caracal), who received more negativity from participants and who had the highest persecution rates in my study area. This result could potentially be explained by a combination of generationally taught hatred towards certain species and due to the perceived livestock loss (e.g. livestock size and species) caused by each predator species. It is important to research and monitor wildcats outside protected areas to obtain a deeper knowledge of wildcat behaviour, abundance, population dynamics and other aspects of their ecology. By doing this, specific conservation and management questions can be addressed and through the knowledge of the natural history of a species, conservation failures can be avoided. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2021

  • Description: Over the years, there have been complaints of poor service delivery in Zimbabwe’s Urban Councils. Newspapers in Zimbabwe have been filled with stories of poor service delivery and citizen grievances. Existing literature on service delivery has focused on the causes of poor service delivery, blaming them solely on the local government authorities. The literature has blamed poor service delivery in Zimbabwe on corruption, polarisation, politicisation, and incapacitation amongst other things. What is not highlighted is the role that citizens play and their responsibility in ensuring that there is proper service delivery. This thesis discusses the ways in which citizens participate in local government service delivery in Chiredzi which is an urban Council in Zimbabwe. To establish citizen participation in Chiredzi, this theory draws upon the social capital theory focusing on its trust, network, and norms aspect. Social capital facilitates an analysis of citizen participation and service delivery in Chiredzi. For this study,a qualitative research methodology was used. This methodology consisted of semi-structured telephone interviews with participants together with relevant documents. It was concluded that there is a need to educate citizens on their roles and responsibilities in local government to improve the state of service delivery. , Thesis (MSocSci) -- Faculty of Humanities, Sociology, 2021

  • Description: The purpose of this Namibian case study was to investigate how different types of gestures are used to support the construction of mathematical meaning making in teaching and learning. Gestures of three selected Grade 8 mathematics teachers were observed and analysed. This study was intended to answer the following research question: how do selected Grade 8 mathematics teachers use gestures as visualisation tools to support mathematical meaning making? The study was framed by an enactivist perspective and the research was oriented in the interpretive paradigm. Data were collected through video-recorded observations of three selected teachers and through stimulus recall interviews. In order to generate rich data and support validity, five lessons per selected teacher were video recorded. The study found that the participating teachers incorporated a variety of mathematical gestures into their lessons in order to support and provide mathematical meaning. Further, this study found that gestures facilitated meaning making in mathematics. The findings in the study suggest a need for mathematics teachers to be trained in using gestures appropriately to communicate mathematically in their lessons. In addition, this study discovered a new type of gesture – the overlapping gesture in addition to McNeill's (1992) types, namely: pointing gestures, metaphor gestures, beating gestures and iconic gestures. This case study also showed that the more experienced the teachers are, the more mathematical gestures they produce during their mathematics lessons. , Thesis (MEd) -- Faculty of Education, Education, 2021
