- Description: The predictive nature of the yield curve has been of interest to researchers for years. In this thesis, the evidence for the yield curve as a predictor is examine, specifically as a predictor for bear markets in the JSE stock market for 8 sub-sectoral indices. The study explores a dynamic market timing strategy for timing the South African stock market compared to a normal buy-and-hold strategy. First, probit models are estimated for each of the sectoral indices which did not prove to have tracked well all the bear market phases. Then a dynamic market timing portfolio is simulated against a buy-and-hold only strategy, the dynamic market timing portfolio proved to have outperformed a buy-and-hold strategy for almost all the indices. Thus, a Henriksson-Merton parametric model test which tests for market timing ability was done on these sub-indices. The research finds that the yield curve in South Africa is not a useful tool for a buy-sell strategy for most of the sub-sectoral indices of the JSE. , Thesis (MCom) -- Faculty of Commerce, Economics and Economic History, 2023

- Description: Climate change has caused a combination of effects on the physiology of fishes. Of particular concern are the effects of thermal variability and ocean acidification. Organismal energy budgets change throughout ontogeny and research into the metabolic scope during early life stages is particularly useful in identifying potential bottlenecks. The first part of this thesis aimed to assess the absolute aerobic scope (AAS, described as the difference between the maximum and standard metabolic rates) of individual juveniles from a protected population of the endemic, commercially important seabream, Chrysoblephus laticeps, across a range of ecologically relevant temperatures (T = 11, 14, 18, 22˚C) under present-day conditions (pH = 8.03, pCO2 ≈ 420 μatm) using intermittent flow respirometry. The second component sought to investigate how long-term exposure (from fertilisation to juvenile, ~100 days exposure) to high-pCO2/hypercapnic conditions (pH = 7.63, pCO2 ≈ 1400 μatm), would affect the AAS of juvenile C. laticeps over a range of temperatures. Lower pH conditions were predicted to cause a decrease in the AAS of treatment animals due to additional energetic costs of acid-base regulation. The findings of the first data chapter demonstrated that juvenile C. laticeps reared under current CO2 conditions are tolerant to a wide range of thermal conditions, and individuals with a broad aerobic scope will be the best suited to coping with enhanced thermal variability. In contrast to the expected outcomes of the second data chapter, juvenile C. laticeps reared under high pCO2 conditions displayed greater AAS at high and low temperatures when compared with specimens from high pH conditions. Whilst a high degree of individual phenotypic variation was observed in the metabolic response of both groups, this was reduced at the lower and upper extreme temperatures for high pH and low pH animals respectively. Notably, the variation in treatment animal’s SMR was significantly diminished across all temperatures tested, compared to only a localised reduction in the SMR of high pH animals at cold temperatures. This may be indicative of compensatory pathways affecting energy restructuring and thermally-governed physiological trade-offs under hypercapnia. Given these results, juvenile C. laticeps appear to be more resilient to ocean acidification than anticipated, potentially owing to intrapopulation metabolic phenotypic diversity. This is likely attributed to the parental lineage originating in the Tsitsikamma MPA, which is thought to boast greater phenotypic diversity as a consequence of the refuge that these conservation areas offer from exploitation. Owing to the restriction imposed by the availability of surviving, captive-reared juveniles, the sample size used in this study was relatively low. However, owing to the repeated-measures nature of this research the sample size was sufficient to offer suitable statistical power for the polynomial mixed model used in the analysis. Future research should incorporate both physiological and behavioural responses to multiple environmental stressors to better understand covariation between these two traits, and to detect any behavioural trade-offs that might arise through compensation. In addition, these trials should be repeated using offspring from outside of the MPA to compare whether the same level of resilience and metabolic phenotypic diversity would be present in an exploited population. , Thesis (MSc) -- Faculty of Science, Ichthyology and Fisheries Science, 2023

- Description: The Namibian Science curriculum acknowledges that indigenous knowledge (IK) is an important basis for learning science. Among the shared reasons is that it provides learners with access to abstract scientific concepts. As a result, teachers are encouraged to integrate IK into the teaching and learning of science. However, it seems that there are no explicit guidelines on how IK should be integrated into science classrooms. It is against this backdrop that this study sought to explore how the indigenous technology of making oshikundu (a non-alcoholic beverage) can be mobilised by Grade 8 Life Science teachers to mediate learning of diffusion in their classrooms. The study was underpinned by interpretive and indigenous research paradigms. Within these paradigms, a qualitative case study approach was employed. Four Grade 8 Life Science teachers from four different schools in Okahandja town, Otjozondjupa Region, Namibia, participated in this study. Additionally, an expert community member who was knowledgeable about the indigenous technology of making oshikundu was requested to demonstrate how to make it. In this event, the Life Science teachers had to identify the science concepts embedded in the practice. To gather data, this study made use of semi-structured interviews, workshop discussions, observations and journal reflections. Vygotsky’s sociocultural theory was used as a theoretical framework and Mavhunga and Rollnick’s topic-specific pedagogical content knowledge (TSPCK) was used as an analytical framework. The findings of this study revealed that the teachers’ understanding was positively influenced by the integration of IK which certainly assisted them to relate better to the concept of diffusion. This was validated when teachers extracted emerging science concepts from the indigenous technology of making oshikundu. The implication of this study is that expert community member presentations can greatly enhance sense making of science concepts. The study thus recommends that school-based teachers’ continuing professional development in collaboration with expert community members should be carried out to enhance both the teachers’ subject content knowledge and pedagogical content knowledge on IK integration. , Thesis (MEd) -- Faculty of Education, Secondary and Post-School Education, 2023

- Description: The discourse of identity and community are topics of interest to me. As a citizen living in post-apartheid South Africa, I am captivated by the re-emerging wisdom and knowledge of Nguni cultural philosophies and practices. My practice-based research is interested in a creative interpretation of these ancient philosophies and practices in the context of postcolonial life. The project in many ways re-members through observation of socio-political issues such as inequality, violence, and vandalism as reflections of internal challenges of the individual self in current reality. In essence, my discussion in this paper highlights the need for healing grief and loss for the well-being – physical, emotional, mental, and spiritual – of society. Self-definition is the core of any community and we see this in the philosophy of the African proverb umntu ngumntu ngabantu, ‘I am because you are’. ‘I am’ is a set of beliefs that construct the individual self; our life’s course then becomes a constant molding of the body and the world around us. The wisdom of ubuntu was, and is, a catalyst for many African cultures, as this law recognizes each individual as important and equal in the community. As a descendant of various indigenous clans originating in Africa the well-being and balance of my being is determined by how much I know about who I am. Consequently, being a part of the generation that is experiencing the transitioning phases from apartheid I question the ways we are dealing with the residue of coloniality concerning all aspects of self; the physical, emotional, and mental bodies of self. My creative work is a reflection of the exercises I implemented to cultivate selfhood as a way to participate in and control my reality as a marginalized member of society. The different chapters touch on many intersecting theories about tools for healing/soothing the self. The creative process experimented with the various concepts embedded in the expression ‘I am because you are’. In the process of this research, I learned that knowing yourself is one of the principles of ubuntu, which teaches me that I cannot be or give what I do not have. The themes I explore through the above expression are self-love, self-acceptance, and self-respect using a creative lens. This practice-based research proposes a concept; the act of love as a decolonial gesture. My exhibition Vuleka Mhlaba Ndinegene1 utilizes visual language to convey the need for more conversations on healing using natural elements, as a way to make a connection between self, the natural environment, and community. In the first and second chapters, the paper focuses on practices employed by artists such as Lhola Amira, Guadalupe Maravilla, Buhlebezwe Siwani, Tony Gum, Lina Iris Viktor, and Aida Muleneh, to relate the various approaches to re-member the severed connection between self, nature, and community. This study looks at theories on; holding space, sound healing, earthing, shadow work, astrology, and human consciousness. , Thesis (MFA) -- Faculty of Humanities, Fine Art, 2023

Visual representations of linear algebraic expressions: a case study in a Grade 9 after-school mathematics club

- Description: Visualisation is commonly used as a tool in introducing algebra through visual or kinaesthetic sequences designed to prompt learners' development of a general rule for moving from a term's position to its output value. Fluency in both the concepts and the conventions of elementary algebra are essential to learners, as algebra forms the language in which many advanced mathematical ideas are encoded. Moreover, algebraic fluency is often associated with an ability to think abstractly about arithmetic processes. In many classrooms, however, research has shown that learners often focus on fluency in algebraic conventions rather than concepts, learning how to manipulate expressions without understanding the algorithms they are taught to follow. This trend can be linked to several causes, including teacher-centred mathematics classrooms in which learners are – whether implicitly or explicitly – encouraged to copy formulae and methods in order to ‘get it right in a test’ without necessarily grasping the underlying logical relationships. This case study, therefore, aimed to determine whether there was value in using visual, kinaesthetic models to broaden and deepen learners' use of algebra. To that end, in the context of an extra-curricular mathematics club that aimed to decentre the teachers and demand innovative ideas of the participants, six pairs of Grade 9 learners were tasked with creating visual representations of a linear algebraic expression using coloured building cubes. The responses to this task over the course of five assignments were many and varied and almost universally displayed a sustained internal logic that the learners were able to explain and develop. Most pairs began with a visual list of terms arranged in sets of towers, pyramids or, in one case, a spiral. At the end of the study, all but one of the pairs had settled on a Visual Expression, in which various colours were used to represent elements of the algebra such as the values of the coefficient, the variable and the constant term. The participants' representations grew in complexity over the course of the study and the conformity of the final responses showed that the club was a collaborative space in which learners shared ideas. However, the structure of the Visual Expressions and their own confessions of nerves about ‘getting it wrong’ in the interviews suggest that the participants were stuck in a mindset that led them to seek out and idealise the representation closest to the original algebra, even though that representation revealed little about the structural relationship underlying the expression. , Thesis (MEd) -- Faculty of Education, Secondary and Post-School Education, 2023

- Description: This dissertation tests the claim made by a large membership-based organisation that it is a social movement. The organisation, Vulamasango Singene (VS) operates across the rural areas of large parts of the Eastern Cape Province. It has, for twenty years, advocated for the re-opening of land restitution claims for a specific category of forced removal known as “betterment”. This study provides an analysis of an organisation that has yet to achieve its objective in spite of sufficient financial resources, logistical and strategic support, numeric strength and the legal clarity of its demand. The research is situated within the framework of social movement theory. The study examined the origins, institutional infrastructure, demographic make-up, activities and culture of VS. These were analysed against four components that are identified in the literature as key characteristics of a social movement. These are: (i) informal networks (as opposed to structured and managed engagements); (ii) a plurality of actors (as opposed to a homogenous grouping); (iii) mobilising around issues of conflict; and (iv) sharing common beliefs and demonstrating solidarity. Data were gathered through an archival study and field research. Semi-structured interviews were carried out with a sample of VS’s leadership, and staff of the non-governmental organisation in which VS originated, as well as expert informants in the land reform arena. The findings with respect to each of the criteria were: (i) VS’s structure was rigid and internal communication was largely formal. (ii) There was almost no demographic or political diversity within VS. (iii) VS had, in the past, mobilised around issues of conflict, but there had been no mobilisation for ten years. (iv) While there was some evidence of sharing common beliefs and demonstrating solidarity, this was limited. The conclusion reached was that VS is not a social movement. This does not imply that VS is not an important democratic or representative organisation. It does, however, provide a theoretical position from which VS, and other organisations, can direct further action. The study touched on the relationship between northern donors, local professional NGOs and grassroots organisations in South Africa. Interactions among these institutions impact on the way that organisations and social movements develop. Comparisons with other similar organisations were made and similarities and differences were highlighted. It was suggested that, because of the importance of the issue, further research in this regard is necessary. , Thesis (MA) -- Faculty of Humanities, Sociology, 2023

These are: (i) informal networks (as opposed to structured and managed engagements); (ii) a plurality of actors (as opposed to a homogenous grouping); (iii) mobilising around issues of conflict; and (iv) sharing common beliefs and demonstrating solidarity. Data were gathered through an archival study and field research. Semi-structured interviews were carried out with a sample of VS’s leadership, and staff of the non-governmental organisation in which VS originated, as well as expert informants in the land reform arena. The findings with respect to each of the criteria were: (i) VS’s structure was rigid and internal communication was largely formal. (ii) There was almost no demographic or political diversity within VS. (iii) VS had, in the past, mobilised around issues of conflict, but there had been no mobilisation for ten years. (iv) While there was some evidence of sharing common beliefs and demonstrating solidarity, this was limited. The conclusion reached was that VS is not a social movement. This does not imply that VS is not an important democratic or representative organisation. It does, however, provide a theoretical position from which VS, and other organisations, can direct further action. The study touched on the relationship between northern donors, local professional NGOs and grassroots organisations in South Africa. Interactions among these institutions impact on the way that organisations and social movements develop. Comparisons with other similar organisations were made and similarities and differences were highlighted. It was suggested that, because of the importance of the issue, further research in this regard is necessary. , Thesis (MA) -- Faculty of Humanities, Sociology, 2023

- Description: Poor service delivery is a challenge that has continued to plague the constitutional democracy of South Africa. Legislation has, in response, been passed to ensure efficient service delivery. Despite this legislation, municipal service delivery has been alarmingly poor, and reports on municipal performance and newspaper articles have corroborated this. On the causes of poor service delivery, the existing literature appears to have focused on financial mismanagement, corruption, and the incapacity of officials. Absent from existing literature are discussions on how municipal service delivery is affected by the lack of interrelatedness between municipal public resource management processes (such as revenue collection, expenditure management and oversight). This dissertation addresses this gap by examining the municipal public resource management processes from an oversight perspective. The study sought to analyse the effectiveness of year-end oversight at Amathole District Municipality (ADM) over water and sanitation services. This research aimed to study the year-end oversight over service delivery with reference to the Municipal Public Resource Management (MPRM) model. According to the model, effective service delivery includes inter alia effective oversight, as oversight forms part of the entire system of the municipal resource management cycle. Thus, for the MPRM model, oversight should be exercised on all these processes. The research was a desktop analysis that used both a qualitative and quantitative research methodology. The primary document analysed was the ADM Oversight Report (OR). This report is produced by the Municipal Public Accounts Committee (MPAC) and reflects the year-end oversight conducted by the MPAC on the municipality's activities. In the analysis of the OR, it was concluded that the ADM MPAC had failed to conduct effective year-end oversight of W&S services. The efficacy of the ADM MPAC's year-end oversight was measured against guidelines for effective year-end oversight from the National Treasury and the MPRM model. The findings suggested that there were inefficiencies in the manner that the ADM MPAC exercised its year-end oversight. , Thesis (MA) -- Faculty of Humanities, Sociology, 2023

- Description: Although the Rwandan genocide (itsembabwoko in Kinyarwanda) has often been compared with the Holocaust, in terms of literary and cinematic narratives it has been largely underrepresented, with the notable exception of the release of the films Hotel Rwanda (2004) and Sometimes in April (2005), as well as novels such as Gil Courtemanche’s A Sunday at the Pool in Kigali (2003). However, although there is now a larger oeuvre of works on the subject, they are often not widely known or disseminated beyond their countries of origin. Of even greater concern is the fact that most cinematic narratives on itsembabwoko rely on Western narrative structures in their approach to storytelling. As a result, trauma in these narratives largely tends to focus on the experiences of Western protagonists or on Rwandan protagonists from a Western point of view. This tendency can be tied to the use of Western trauma theory in exploring the effects of the genocide on its witnesses and survivors, at the expense of arguably more relevant postcolonial trauma theory. This presents a problem in theorising the trauma of itsembabwoko, which occurred in a highly specific historical context involving the processes of colonization and decolonization, and in which the difficulties in unifying a population which had been split along socio-economic lines since pre-colonial times remained unresolved. Despite its shortcomings in the postcolonial African context, it would be a mistake to dismiss Yale trauma theory entirely, however, since theorists such as Cathy Caruth still provide valuable insights into the effects of trauma on both the individual and the collective. As a result, I have sought to find commonalities between the two schools of thought, so as to create a more nuanced view of itsembabwoko, its repercussions and the violence preceding it. In writing this thesis, I have selected mostly Rwandan authors, often survivors of the genocide, whose works provide an alternative view of Rwanda’s violent history to that presented in the works mentioned above. Given that the majority of the texts I focus on have been released more recently – mostly the mid-2010s – and are less well-known than their Western counterparts, they provide the opportunity to compare first-hand accounts with those that can only partially recreate the terror of anti-Tutsi violence in Rwanda. My analysis hopefully provides a new perspective on the dominant narratives which have shaped the way in which non-Rwandan (predominantly Western) audiences understand the genocide. The overall aim of this thesis, then, is to demonstrate the importance of placing the genocide and its resultant trauma in a broader historical context, with a view to establishing that it is shortsighted to ignore the impact of pre- and post-genocide trauma on the Rwandan people when discussing itsembabwoko. Though this has been achieved in socio-historical studies, such as Mahmood Mamdani’s When Victims Become Killers: Colonialism, Nativism, and the Genocide in Rwanda, very little has been produced on literary and cinematic representations of the genocide. , Thesis (MA) -- Faculty of Humanities, Literary Studies in English 2023

- Description: Oenothera species (Myrtales: Onagraceae), commonly known as evening primroses, were introduced to South Africa for various purposes, where they established alien populations and expanded their distribution nationwide. Although some of these species are listed as emerging invaders in South Africa, their invasive status is currently unclear. This study assessed the invasive status of eight Oenothera species listed as emerging invaders in South Africa, namely, O. biennis, O. glazioviana, O. laciniata, O. indecora, O. stricta, O. jamesii and O. rosea. The study also focused on the biotic interactions of Oenothera with native arthropod species to assess any potential ecological impacts. The distribution of the eight Oenothera species was mapped using available occurrence records from sources such as the SAPIA database, herbarium records, and BRAHMS database. Additional records were collected by conducting field surveys in KwaZulu- Natal and Eastern Cape provinces. The distribution of these species was mapped using QGIS. Most Oenothera species were found in the Eastern Cape, KwaZulu-Natal, Gauteng, Free State, Mpumalanga and Western Cape provinces, while North-West, Northern Cape, and Limpopo provinces had fewer species. The grassland, savanna and fynbos biomes had more Oenothera species than other biomes in South Africa. The results indicated that O. biennis, O. glaziviana, and O. rosea are spreading at a preceding rate. In South Africa, the species flower predominantly in the spring and summer seasons. Species distribution modelling was conducted using Maxent to identify climatically suitable areas for establishing evening primrose populations. Species distribution models results show that the climatically suitable areas are concentrated in the central, eastern, and south-western regions of South Africa. The most considerable climatic variables contributing to the distribution of most Oenothera species were the annual mean temperature and precipitation during the driest month. To evaluate biotic interactions between native arthropods and Oenothera species and assess the potential ecological impacts, arthropods were collected from two Oenothera species (O. biennis and O. glazioviana) in different localities (only in Eastern Cape: East London and Fort Beaufort). The arthropods collected were identified, and diversity indices were calculated to determine the diversity of native arthropods collected in sites where these species are present. The overall number of individual arthropods collected was 768, belonging to six orders. These arthropod species belong to three feeding guilds: herbivores, predators, and palynivores. The ANOVA results showed that these species statistically differ in diversity for all the diversity indices. Overall, there were significant interactions between the arthropods’ orders and their feeding guilds. Lastly, the risk analysis framework assessed the potential for managing and listing two species (O. biennis and O. rosea) in the NEM: BA A&IS list. After considering all the likelihood elements, environmental, socioeconomic, and potential impacts, the risks posed by Oenothera biennis in South Africa were found to be high. The recommendation of this analysis suggests that O. biennis and O. rosea species be listed as category 1b in the NEMBA A & IS regulations list. The results of this study indicate that these congeners experience ecological differences, resulting in their varied distribution and invasion. Furthermore, they offer new insights regarding the geographical patterns and potential distribution of Oenothera species in South Africa. Moreover, it also provides recommendations for the management of the species in the South African context. , Thesis (MSc) -- Faculty of Science and Agriculture, 2023

- Description: The Covid-19 pandemic has created the largest disruption of education systems in human history. The closure of schools and other learning spaces has impacted billions of learners worldwide. The mitigative measures and many new standard operating procedures have brought restrictions and many challenges. The face-to-face traditional teaching method lost its value, and teaching shifted to distance through the integration of technologies. The integration of technologies necessitated the emergency remote teaching process, as it is one of the distance teaching modes that can make teaching possible even for less technologically privileged nations. Literature has shown that the integration and usage of technology during teaching support the development of technological pedagogical and content knowledge (TPACK) of teachers. This study, therefore, sought to investigate how the integration and use of technology during the emergency remote teaching of Covid-19 developed the secondary school teachers’ technological pedagogical and content knowledge. The study is underpinned by an interpretive paradigm, and a qualitative case study approach was employed. It was conducted in seven secondary schools in the Endola education circuit, Ohangwena region, with the purposeful participation of twenty-six secondary school teachers. Data was collected using semi-structured questionnaires and semi-structured interviews. The study was informed by Vygotsky’s (1978) sociocultural theory together with the TPACK framework of Thompson and Mishra (2007) as both theoretical and analytical frameworks. The study's results showed that teachers made use of existing technological resources to sustain their teaching efforts during ERT. They encountered various challenges, including a lack of technological expertise (knowledge) among both teachers and learners. The shift to virtual instruction during ERT supported teachers in developing proficient technological pedagogical content knowledge. This research concludes that schools possess the necessary technological infrastructure to enable teachers to incorporate technology into their teaching methods. Furthermore, it highlights that teachers generally hold favourable attitudes toward integrating technology into their instruction. Nevertheless, it recommends that there is a need for improving both in-service and pre-service teachers’ training and support for effectively teaching in online and blended learning environments. , Thesis (MEd) -- Faculty of Education, Secondary and Post-School Education, 2023

- Description: This study investigated the Granger causality of tourism and economic growth in the Republics of Botswana and Madagascar during the period 1995 2019. The study was inspired by speculation regarding the influence of tourism on the economic growth of the two countries, given that the literature cautions that the relationship is not always direct and obvious, but rather depends on the country and changes over time. The ARDL-bounds F-test was used to test for co-integration and for Granger causality, with the ECM-based multivariate Granger-causality test used. The results confirm that tourism and economic growth have a prevailing stable, long-run co-integration in both countries, with a unidirectional causation, in that tourism is propelled by economic growth. These findings support the growth-led tourism GDP TOR hypothesis for both countries, and do not corroborate the popular tourism-led growth TPR GDP hypothesis. The study findings imply that both countries’ rich natural resources are insufficient to propel tourism growth and drive GDP in the absence of a supportive economic environment. The study therefore recommends that investment and policy efforts in Botswana and Madagascar focus more on overall economic development than at tourism per se. This would create an environment conducive for attracting and retaining visitors to these countries, and thus boost tourism. , Thesis (MSc) -- Faculty of Science and Agriculture, 2023

- Description: Wildfires are complicated incidents that arise as results of both natural causes and anthropological activities. They have long been regarded as the most devastating phenomena globally. Wildfires are considered a powerful natural factor which has detrimental effect on the global environment. This study was aimed at developing logit calibration models for wildfire smoke prediction based on Sentinel-2 multispectral data and machine learning techniques. Remotely sensed data, in the form of the Sentinel-2 imagery, was used as the base from which wildfire smoke plumes were spectrally characterized and distinguished from clouds and flame using endmember selection. The Smoke Detection Index (SDI) was generated to detect the relative abundance of smoke from the imagery. The Cloud Detection Index (CDI) was also generated from Sentinel-2 imagery to detect the relative abundance of clouds. The bi-level thresholding technique was also used to characterize wildfire smoke from the imagery. The logit models were developed through multilayer perceptron (MLP) neural network to predict wildfire smoke plumes. The Relative Operator Characteristic - Area Under the Curve (ROC-AUC) metrics was used to evaluate the logit models performance. The spectral signature pattern from endmembers revealed that wildfire smoke behaves different across Sentinel-2 multispectral channels with shortwave 1 channel (SWIR-1) exhibiting the highest radiance value. The signature patterns from endmember selection also revealed the distinctive spectral characterization of smoke from those of clouds. The findings showed that whilst smoke exhibited high radiance value on SWIR-1 channel, clouds exhibited high radiance value in the near infrared (NIR), signifying that smoke and cloud are spectrally separatable in the NIR. The smoke-containing pixels from bi-level thresholding were characterized by SDI values that ranged between 0.089 and 0.561. Suggesting that pixels associated with wildfire smoke are limited to this range of values. The logit models developed showed that smoke is predicted in SWIR-2. The ROC-AUC value obtained by this model was 0.77. The Implications emerging from the ROC-AUC results revealed that MLP model employed on the SWIR-2 band present a viable and accurate prediction of wildfire smoke plume. The findings of this study suggest that wildfire smoke is efficiently predicted at the shortwave channels of the electromagnetic spectrum. The wildfire smoke can be spectrally distinguished from cloud in the near infrared channel. , Thesis (MSc) -- Faculty of Science and Agriculture, 2023

Suggesting that pixels associated with wildfire smoke are limited to this range of values. The logit models developed showed that smoke is predicted in SWIR-2. The ROC-AUC value obtained by this model was 0.77. The Implications emerging from the ROC-AUC results revealed that MLP model employed on the SWIR-2 band present a viable and accurate prediction of wildfire smoke plume. The findings of this study suggest that wildfire smoke is efficiently predicted at the shortwave channels of the electromagnetic spectrum. The wildfire smoke can be spectrally distinguished from cloud in the near infrared channel. , Thesis (MSc) -- Faculty of Science and Agriculture, 2023

- Description: A disease named COVID-19 almost destroyed the human population. It is caused by the SARS CoV 2 virus which emerged in 2019 and rapidly spread worldwide forcing all countries to shut down. This virus uses non-structural proteins to complete its invasion and development inside the host. The non-structural protein 2 NSP2 defined as the RNA binding protein involved in coronavirus genome replication and decreases the human immune response is key for this virus’s development and invasion. It is believed that the NSP2 associate themselves with polyamines and heat shock proteins inside the host cell, to proceed with the viral development and this study aimed to investigate how SARS CoV 2 virus key non-structural proteins NSP2 utilizes polyamines and heat shock proteins using the molecular docking approach and molecular dynamics MD. In this present study a docking approach was used. The dockings were done on ClusPro, and analysis was done on Discovery Studio, chimera, and PyMOL. One of the enzymes that are involved in the regulation of polyamine biosynthesis, adenosylmethionine decarboxylase AdoMetDC was used in investigating the polyamine binding to the viral NSP2, and major heat shock proteins HSPs HSP40, HSP70, and HSP90 were used in the investigation of the binding of HSPs to viral non-structural proteins NSP2. The results obtained show that 32 interactions were formed when docking heat shock protein 40 HSP40 with the SARS CoV 2 NSP2, but the area that has the highest interactions was from amino acid Ala554 to His557. Asp553 plays a very crucial role in this interaction forming six interactions. Heat shock protein 70 produced about 28 interactions when docked with the SARS CoV 2 NSP2. But the section with the most bonds was from position 550 to 560 of the ligand. Human heat shock protein 90 HSP90 formed 19 interactions when docked with the SARS CoV 2 viral NSP2. MD revealed Arg458, Asn508, Met297, Arg301 and Tr417 active residues. And pharmacophore modeling indicated zinc inhibitors as crucial for inhibiting this virus. Enough interactions were produced with ideal bonds lengths, and it can be said that the functioning of the SARS CoV2 viral non-structural proteins functioning majorly depends on the presence of the heat shock proteins at hand for proper formation and depends on polyamines for complete development and correct functioning. , Thesis (MSc) -- Faculty of Science and Agriculture, 2023

- Description: Root crops, such as sweet potatoes, are important sources of carbohydrates in the pacific region where soils are generally of inferior quality. Sweet potato leaves are said to be more nutritious when compared with storage roots, therefore can be used as a source of nutrition by human beings. Sweet potatoes like other vegetables are perishable and therefore they need to be processed in order to increase storage life. The shelf life of perishable vegetables can be increased by the use of drying methods. This brings an opportunity area for research to realize the full potential of sweet potatoes. Sweet potatoes can be developed as a sustainable crop for diverse nutritionally enhanced and value-added food products to promote human nutrition. Thus, the study sought to develop nitrogen level that could result in maximum yield of tubers while the green leaves are harvested for human consumption. The study also sought to find the best suitable drying method to extend the shelf life of orange-fleshed sweet potatoes OFSP leaves. The research was conducted at the University of Fort Hare glasshouse, Alice, in the Eastern Cape Province of South Africa. OFSP plants were grown at the UFH research farm, harvested and sorted according to their different age groups. The leaves were then taken to the glasshouse for the experiment to be conducted. The first experiment followed CRD 4x3 factorial replicated 3 times, with 4 levels of leaf age (upper, middle, lower, basal) and 3 levels of drying sun, shade, oven. The second experiment followed a RCBD replicated five times, with 4 levels of N 50 100 150, and 200 kgha randomly allocated. All the nutritional analysis was done based on the recommendations by the Association of Official Chemists A.O.A.C. Statistical analysis was done using SAS, Version 9.1. Where a significant difference was detected, variable means were separated using Fisher’s protected least significant difference p 0.05. , Thesis (MSc) -- Faculty of Science and Agriculture, 2023

- Description: Excerpt from Introduction: My interest in the Zulu royal family intensified as I began to read many stories and have lengthy conversations with members of the Zulu royal family and others, including Dr Maxwell Shamase (University of Zululand), about Zulu history. I was struck by the power and prowess of Princess Mkabayi (1750-1843). The elders were said to be speechless when she spoke. According to Shamase, a common Zulu expression which references Mkabayi’s well-known verbal skill is Umuntu ukhuluma kome umlomo, and translates as [like Mkabayi] the speaker speaks clearly and leaves no room for misunderstandings and misinterpretations. I found her to be a brilliant strategist with a servant heart and one whom history had not given due credit, and I was inspired to bring her story to life by setting it to music. I wanted to explore whether or not the events surrounding Mkabayi led to a change of consciousness among the Zulu nation, and I used this as a theme for my symphonic work about her. The lives of Queen Nandi (King Shaka’s mother) and Princess Mkabayi (King Shaka’s aunt) made for fascinating stories I had been privileged to discover, and I felt they were South African treasures to be elevated and shared with the world. The two works listed above form part of my repertoire based on Zulu royal history which are collectively known as “The Royal Trilogy,” and I have come to think of them as part of a developing “urban classical repertoire”. The Royal Trilogy is a set of three compositions with 33 independent scenes linking historical events and people. It includes the following entitled symphonic works for full orchestra: Nandi iNdlovukazi yezi Ndlovukazi (hereinafter “Queen Nandi”), Inkosazane Mkabayi (hereinafter “Princess Mkabayi”), and iNkosi uShaka: Umbono, Isizwe, Isiphetho - King Shaka: A Vision, A Nation, A Destiny (hereinafter “King Shaka”). Nandi premiered on 22 September 2016 as part of “A Musical Tribute Celebrating 200 Years of the Zulu Monarchy,” and “Mkabayi” premiered on 6 September 2018 under a programme titled “Princess Mkabayi: Celebrating Heritage Month”. Both pieces were performed at the Durban City Hall by the KwaZulu-Natal Philharmonic Orchestra with a mass Zulu choir (combination of the Clermont Community Choir, Prince Mshiyeni Choir, and Thokozani Choral Society) for socio-economic and ethnically diverse audiences. The final work, “King Shaka,” is expected to premiere in 2023. A future adaption of the Royal Trilogy is envisioned as an Afro Fusion Contemporary Ballet. , Thesis (MMus) -- Faculty of Humanities, Music & Musicology, 2023

A critical analysis of the criteria applied in South Africa to distinguish an independent contractor from an employee for income tax purposes

- Description: The study set out to critically analyse the criteria used by South Africa to determine the distinction between independent contractors and employees. Comparisons are also drawn with the criteria used in the United Kingdom(UK) and New Zealand (NZ) to assess whether there are new ideas that can be drawn from these and help improve the criteria used in South Africa. This was motivated by the ongoing debates around this issue and the desire to make a contribution that might bring some new insights and clarity. Under South African tax legislation employers are only obliged to deduct income tax from persons identified as employees while on the other hand, they cannot deduct tax contributions from the money paid to independent contractors for services rendered. Furthermore, there is no statutory definition for the term “independent contractor” in the Income Tax Act of South Africa nor in the country’s labour legislation. The definition of this term has largely been established by the labour courts in instances where disputes have arisen around these matters. Using a doctrinal research method (including a comparative legal research), which is a qualitative research approach, articles, statutes, judgements, explanatory memoranda, and policy documents on the subject under investigation were analysed. It is submitted that the criteria used in the two countries used in the comparison are similar to the ones used in South Africa, with some variations. All three countries use similar tests to make their determinations and a survey of the UK and NZ’s case law indicates that the most preferred criteria are the multifactoral approach to determine the true nature of the relationship between employers and their employees. This approach has been found to be more flexible which allows it to accommodate the changes that are occurring in the world of work. In the South African context, the labour court has adopted a substance-over-form approach in making their determinations, arguing that the nature of the working relationship between employer and employee is a more important indicator than the mere contents of a written contract. The labour court has also used labour legislation mainly to assist in the interpretation of the distinction between independent contractors and employees. The study established that the criteria used in the UK is a bit more complex because workers are put in three different categories and the definition of employee is not 4 uniform in all the available statutes. In New Zealand the multiple factor approach is preferred just like in South Africa. In conclusion is submitted that the study established that there is nothing, other than the UK’s Mutuality of Obligation Test, that would assist in further clarifying the criteria used to classify employees or independent contractors in South Africa , Thesis (MA) -- Faculty of Faculty of Business and Economic Sciences, 2023

- Description: According to the Progress in International Reading Literacy Study (PIRLS, 2016), 78% of grade four children in South Africa's poorest communities lack access to adequate educational resources and infrastructure, which prevents them from reading for meaning in any language. Children in South Africa lack the foundational reading abilities required to finish grade four in compliance with international standards. This project used the participatory action learning and action research (PALAR) approach to prepare mothers to create a digital storybook as learner support material and because participatory action research is a method of evaluation that generates data about an ongoing change process and encourages learning amongst the people most intimately connected to the change. The study centred on the use of digital storytelling as a literacy resource to create learning experiences in the literacy classroom, as well as to determine how PALAR can be used as a methodology to aid mothers in creating a digital storybook. The research objectives guided the workshops held over five weeks with twelve grade four learners’ mothers. I held a two to three-hour, one-day start-up workshop that was recorded and documented. The key advisory set (KAS) members received baseline checklists, which were then sent to the action learning set (ALS) members in their respective groups. The information received from the checklist was used as discussion points in the follow-up workshops. Critical discourse analysis (CDA) served as the foundation for the data analysis. The generated data was interpreted and analysed using Schneider’s (2013) ten work steps. The data-gathering method was based on a qualitative approach and the study was underpinned by critical theory and critical pedagogy that enabled a collective approach which results in greater epistemic justice. The principal, parents, and learning support specialists (LSSs) had informal pre-entry talks before the start of the official data collection. A total of twelve participants were chosen for this study based on their willingness to participate and their being parents or guardians of children in grade four. The research objectives informed three iterative cycles of planning, observing, and reflecting. The usage of both open and closed coding led to the emergence of three main themes, which were understanding literacy, communication between school and parents, and learning materials. iii New categories were created because of the continuous comparison and analysis that were employed between cycles to answer the sub- and main research questions. Data generated throughout the three cycles revealed the mothers' concerns, misconceptions and level of knowledge and commitment to the creation of literacy resources and the possibility of creating a digital storybook. Despite the workshops generating advancement and excitement, the findings indicate that the participants' assessments of their role in the creation of learning materials varied. The report indicates that the parents felt powerless to influence educational decisions based on their past and present experiences regarding their involvement and interaction with the school. It is necessary to employ strategies to put parents at ease and to reassure them that their opinions are important and required to ensure their children’s educational achievement. Essentially, this means ascertaining how to guarantee closer relationships between parents, teachers and learners. Recommendations are made regarding parental involvement in curriculum development based on the study's findings. The recommendations include effective parent-teacher communication through parental involvement in curriculum development, increased parent-teacher interaction to meet learners’ needs more effectively, and finally, an expansion of the study considering a larger sample size, a new study site, and an expansion of the goals beyond the digital storybook. , Thesis (MEd) -- Faculty of Education, 2023

- Description: Students from all over the world now have the opportunity to access a wide variety of high-quality educational resources thanks to the rise of online learn- ing. In recent years, there has been a rise in popularity of online education among both students and teachers. This pattern has only continued to in- crease with the occurrence of global events such as the COVID-19 pandemic, which forced many people to work and study from home. Therefore, it is crucial that online courses are presented in a manner that is suitable for a diverse range of potential students. Many educators lack the necessary experience to move their physical courses to an online environment, which has become a recent trend. Ed- ucators tend to teach in the manner in which they were taught, which may not translate well to online learning delivery. Moreover, many learners today are assumed to possess the necessary knowledge and skills to participate in online learning without much thought. The combination of assumed learner knowledge and lack of online-specific teaching experience can result in the introduction of artificial barriers to the student’s learning by educators. If left unaddressed, these artificial barriers or artificial learning thresholds can cause the student to experience anxiety, a lack of engagement, and a lack of motivation to complete the course for which they are enrolled in. The global expansion of online education has increased the demand for professional training and specialised knowledge to help teachers instruct stu- dents and create online course materials. First, this dissertation highlights some of the success and challenge factors of online learning. It discusses threshold concepts and suggests that artificial barriers or artificial thresholds can hinder online learning.

- Description: Students from all over the world now have the opportunity to access a wide variety of high-quality educational resources thanks to the rise of online learn- ing. In recent years, there has been a rise in popularity of online education among both students and teachers. This pattern has only continued to in- crease with the occurrence of global events such as the COVID-19 pandemic, which forced many people to work and study from home. Therefore, it is crucial that online courses are presented in a manner that is suitable for a diverse range of potential students. Many educators lack the necessary experience to move their physical courses to an online environment, which has become a recent trend. Ed- ucators tend to teach in the manner in which they were taught, which may not translate well to online learning delivery. Moreover, many learners today are assumed to possess the necessary knowledge and skills to participate in online learning without much thought. The combination of assumed learner knowledge and lack of online-specific teaching experience can result in the introduction of artificial barriers to the student’s learning by educators. If left unaddressed, these artificial barriers or artificial learning thresholds can cause the student to experience anxiety, a lack of engagement, and a lack of motivation to complete the course for which they are enrolled in. The global expansion of online education has increased the demand for professional training and specialised knowledge to help teachers instruct stu- dents and create online course materials. First, this dissertation highlights some of the success and challenge factors of online learning. It discusses threshold concepts and suggests that artificial barriers or artificial thresholds can hinder online learning.
