- Description: This study delves into how the worlds of computer gaming and fine art intersect, employing DIY feminism to reflect on the gendered world of gaming and the links between simulation, reality, and fantasy within the game of Minecraft. I argue for a feminine craft (crochet) to challenge masculine gaming oppressions and the lack of representation, acceptance, and visibility for women in gaming culture. My research question is taken from the End Poem seen when the player has beaten the game's main boss. There is a line within the poem that asks, “But what true structure did this player create, in the reality behind the screen?” (End Poem, 2022). This is the question I have sought to answer within this study, by exploring a methodological approach that combines autoethnography and phenomenology to create a reflexive personal narrative. , Thesis (MFA) -- Faculty of Humanities, Fine Art, 2023

- Description: The research by practice is made up of three points of interest that aim to incorporate storytelling into the work with reference to the comic book genre. These points of interest are: experiences of mental health issues from a young man’s perspective, a unique autobiographical experience unpacking the young man’s mental health struggle and African oral traditions. These three points of interest work towards the goal of using African subject matter to uncover and present a meaningful narrative of a young man dealing with mental health problems and his father figure’s ongoing sit-down conversation with him. This mini-thesis breaks down the different components of the research by practice and analyses each component while drawing from various theorists and artists. The mini-thesis also builds up to the idea of using original African subject matter (e.g. African oral traditions, specifically African objects, subjects, and locations) as a means of cultivating a locus of African identity in the comic book industry. The research by practice intersects with this mini-thesis in that it acts as an example of how I visualise African subject matter being used in the theorising and creation of comic books. , Thesis (MFA) -- Faculty of Humanities, Fine Art, 2023

- Description: South Africa is a country that has experienced premature deindustrialisation due to its inability to move out of middle-income status. The role of industrial policy in South Africa is pivotal to taking the country to greater economic heights and a higher-income status. South Africa’s historical context indicates that the country experienced its highest GDP growth rates during the apartheid economy. Since the demise of apartheid, the post-apartheid economy has experienced poverty and economic inequality that the South African government cannot eradicate. This thesis addresses the failure of South Africa to overcome premature deindustrialisation, and it discusses the state of the political economy and economic growth in a pre-apartheid and post-apartheid context. The thesis also addressed the significance of industrial policy through the establishment of the Industrial Policy Action Plan (IPAP). The shortcomings and successes of IPAP form a critical part of the research and present an analysis of different economic sectors. This thesis also assesses the state of industrial policy using two countries as case studies: Brazil and South Korea. , Thesis (MEcon) -- Faculty of Commerce, Economics and Economic History, 2023

- Description: Human movements globally have resulted in dispersal and introduction of terrestrial and marine organisms into areas outside of their native range. Species that have been introduced to new habitats can either be alien (not causing any harm to the new environment) or invasive alien species (destroying or competing with the indigenous species for resources). Investigating the source of these introductions is important as it provides baseline information about their biology and evolution. It also allows for better prevention measures for future invasions and for effective conservation strategies. In this study, I investigate the source of the introduced populations of tropical house geckos Hemidactylus mabouia in the Eastern Cape Province using two mitochondrial gene regions, ribosomal 16S and NADH dehydrogenase subunit 4 (ND4). We also look at the potential spread of these species using species distribution models (SDMs). The phylogeny showed that the introduced populations into the Eastern Cape were genetically similar to both H. mabouia lineages found in Central & Southern Africa. The phylogeny produced two clades from which the majority of the introduced samples were grouped in a clade with samples from Angola, DRC, and Mozambique, and only a few nested within the second clade with the South African native population. Haplotype networks from both genes also showed two clades, matching those found in the phylogeny. The introduced samples were associated with samples from Angola and those from South Africa (native) as these localities had a number of shared haplotypes. SDMs showed less evidence that these individuals could naturally move west down the coast as the probability of occurrence was below 0.4 from the Eastern Cape to the Western Cape. Our conclusion was that the introductions may be due to multiple avenues like species moving down the east coast or human translocation including trade routes. From this we can conclude that geckos are largely translocated through human movement as they are known for their opportunistic behaviours as they are commensal with humans. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2023

- Description: As abalone are slow-growing animals there is a high investment of capital, running costs and labour in commercial abalone farming. Revenue needs to be maximised by achieving fast growth rates. A foremost driver of abalone growth is feed intake and feeding intensity of the abalone as well as the feeding regimen a farm utilises. While feed intake is well-documented in H. midae, there is a paucity of information regarding this aspect in abalone above 70 g and the relationship between feeding intensity, feed conversion rate (FCR) and daily growth rate needs to be documented. Similarly, there are a limited number of studies dealing with the effects of different pellet types of the same formulation, that differ only in shape and size, on feed intake and production in H. midae. This study made use of both a controlled laboratory experiment and commercial-scale farm experiment with the aim of testing whether feed intake information produced under laboratory conditions can provide good estimates of feed intake under farming conditions, which can further be implemented into feeding strategies on abalone farms. This study quantified daily feed intake (F) in 10 – 20 g, 100 – 110 g and 150 – 160 g abalone weight classes using two different pellet types and determined the relationship between the duration of feed availability and feed intake under laboratory conditions. The effect of three different pellet type strategies (fed daily: a leaf-only strategy = L d-1, a short-pellet only strategy = SP d-1, and a strategy that used both = B d-1) on abalone production parameters under farming conditions such as growth rate, feed conversion ratio (FCR), feeding intensity (FI) and weight variation of 30 – 40 g H. midae was also investigated. A commercial-scale farm study was designed to test the effect of four commercially relevant feeding regimens (three size-specific regimens and one commercially practiced feeding method) on the growth, FCR, feeding intensity and weight variation of these three abalone weight classes while taking into account an economic model to assess the profitability of each feeding regimen. Daily feed intake as a percentage of body mass (% BM d-1) was a function of abalone weight class between the 10 – 20 g and two larger weight classes 100 – 110 g and 150 – 160 g p < 0.0001), however feed intake was not different between the 100 – 110 g and 150 – 160 g weight classes. Pellet type did not affect feed intake in all abalone weight classes (p = 0.15). Feed intake (F) was positively linearly correlated with duration of feed availability (h) in the 10 – 20 g weight class (r2 = 0.76, p <0.00001) and logarithmically correlated in the 100 – 110 g (r2 = 0.25, p < 0.02) and 150 – 160 g (r2 = 0.52, p < 0.0001) weight classes (10 – 20 g abalone-1: 3 F (% BM) = 0.02(h) + 0.1976, 100 – 110 g abalone-1: F (% BM) = log10(h)*0.17 + 0.17, 150 – 160 g abalone-1: F (% BM) = log10(h)*0.36 + 0.07). There was no significant difference in monthly average abalone weight, daily growth rate (G), FCR and feeding intensity between each pellet type strategy (G: p = 0.60, FCR: p = 0.62, FI: p = 0.54 ). However, abalone grew well over the 112-day growth period with average abalone weight increasing significantly between each monthly sample time (pooled pellet type strategy: Huynh-Feldt correction; p < 0.00001). Furthermore, abalone fed the leaf-only pellet type strategy (L d-1) fell into higher weight classes after a 112-day growth period (Z test: 50 – 70 g: 72%) which was 16.1 % higher compared to the SP d-1 and B d-1 strategies. Daily growth rate (r2 = 0.34, p < 0.01) and FCR (r2 = 0.42, p < 0.004) was negatively correlated and FCR was positively correlated with daily feeding intensity, respectively (G = - 2.59 (FI) + 1.526, FCR = 8.8082 (FI) – 2.7108). Feeding regimen affected the production parameters of three abalone weight classes. The method practiced on the farm resulted in the best growth in the 10 – 20 g abalone weight class. The farm feeding method resulted in slower yet more efficient growth rates (lowest FCR values) in the abalone weight classes, 100 – 110 g and 150 – 160 g abalone- 1. However, size-specific feeding regimens resulted in the fastest growth rates but resulted in higher FCR values (less efficient). The relationship between feeding intensity, daily growth rate and FCR all showed that an increase in feeding intensity results in increased daily growth rates and FCR values. The economic model suggests that the higher FCR values associated with size-specific regimens, which have higher associated costs to producing abalone, were greatly outweighed by the growth attained by the abalone in the 100 – 110 g and 150 – 160 g weight classes. The size-specific regimens generated a higher potential monetary value of abalone after a 112-day period, which would consequently result in higher income for abalone farms. For abalone ranging from 100 – 110 and 150 – 160 grams, the economic model suggested that in a quarterly grading schedule (112 days) that abalone be fed the size specific daily rations, which is a function of body mass, at 0.35 % BM d-1 and 0.352 % BM d-1, respectively. The two experimental conditions used in this study produced feed intake and production parameter information that is beneficial to South African abalone farmers. The small-scale laboratory study produced information on feed intake that can be used as reference values as to what abalone in these weight classes can consume on a daily basis. The laboratory study can provide estimates of feed intake under farming conditions but should only be used as minimum 4 values when determining size-specific feeding regimens. To maximise abalone growth, farmers should utilise size-specific feeding regimens for abalone above 30 g. Daily growth rate and FCR can be predicted as a function of the abalone’s feeding intensity. Further studies are needed to determine the effects of abalone weight class on production parameters when testing different pellet types as well as an exploration into behavioural studies focusing on diet preferences. Additionally, future studies need to take into consideration abalone above the weight of 100 g with additional focus of research on behavioural, genetic and environmental aspects on abalone feed intake. , Thesis (MSc) -- Faculty of Science, Ichthyology and Fisheries Science, 2023

- Description: In this study, secondary metabolites isolated from Erythrina caffra, a medicinal plant indigenous to South Africa, were investigated. E. caffra is well-known for its healing properties and it is traditionally used for treating bacterial infections like tuberculosis (TB), abscesses, tooth aches and ear infections. Its extracts have also been used to treat cancer. Though many studies have been done on this plant, most of them tended to focus solely on the isolated compounds. In the present study however, extracts, fractions and isolated compounds from E. caffra were evaluated for their anticancer, anti-oxidant, anti-enzymatic, antibacterial and cytotoxicity. The methanol crude extract (B1) from the stem bark of E. caffra was used to extract alkaloidic fractions (B2 and B3) using ethyl acetate and n-butanol respectively, a third fraction (B4) was also extracted using ethyl acetate this fraction was called a neutral fraction. The neutral fraction (B4) was fractionated and through a sequence of column chromatography three active secondary metabolites were isolated. The isolated compounds included Lupeol (1), stigmasterol (2) and 5,7-Dihydroxy-4'-methoxy-3',5'-diprenylflavanone (3). These isolated compounds were characterized and identified using spectroscopic techniques including IR, NMR and high-resolution Mass Spectrometry. Using the cell line HCC-70, isolated from a primary ductal carcinoma, in vitro anticancer assays were carried out on the crude extract from the bark, fractions, isolated compounds and an unseparated mixture of two compounds. These samples were also evaluated for their anti-oxidant, anti-enzymatic, antibacterial and cytotoxicity activities. The crude extract inhibited the cell viability by over 30% and had no effect on the HeLa cells at concentrations of 20μM. Abyssinone V’ 4-methyl-ether (3) and the mixture of stigmasterol (2) and an unidentified compound exhibited potent anticancer activity against the HCC-70 cell line with IC50 of 18.05μM and 9.04μM respectively. Antibacterial assays were also carried out on the crude extracts, fractions and concoctions made from the fractions with the best activity combined with the ones that performed poorly. The concoctions were prepared as two separate series (S and N series). The crude extract inhibited more than 80% of the Staphylococcus aureus cells at a concentration of 20μM with only minimal damage to the HeLa cells. In the concoctions however, the N series managed to inhibit over 96% of the S. aureus while exhibiting no cytotoxicity towards HeLa cells. The extract and its fractions also showed good anti-oxidant activities. Molecular docking of these compounds was done on the Human estrogen receptor (PDB ID:3ERT) and Abyssinone V’ 4-methyl-ether (3) showed the best docking score of -6.6 Kcal/mol, for the simulation against Epidermal growth factor receptor (PDB ID: 1M17) Stigmasterol (2) showed the best docking score of -3.8 Kcal/mol. In silico docking on 3ERT and 1M17 were done to test the binding affinity of the isolated compounds to the proteins which are well known to be overexpressed in some types of cancer. Flavonoids isolated from Erythrina species have been reported to possess good antiplasmodial activity. However, due to the minute amounts isolated in the present study in-vitro assays could not be carried out. Nevertheless, in-silico assays were conducted on the most prominent protozoal parasite which causes malaria in the majority of African countries. In-silico simulations were done against Plasmodium falciparum protein (PDB ID: 7KJH), of the tested compounds Abyssinone V’ 4-methyl-ether (3) was found possess the best docking score of -4.4 Kcal/mol. The molecular docking of 7KJH was done to assess the inhibitory potential of the isolated compounds on protozoal parasites. Pharmacokinetic properties of the isolated compounds were also assessed in silico to assist in evaluating the drug likeness of these compounds. The compounds showed a percent human oral absorption of 100% except for Abyssinone V’ 4-methyl-ether (3), which showed 93.83%, this indicates a remarkable oral bioavailability. Stigamsterol (2) exhibited a Caco-2 cell permeability (QPPCaco) greater than 500 which indicates outstanding results for good intestinal absorption. The compounds also displayed a blood-brain partition co-efficient (QPlogBB) ranging from -1.433 to 0.128 suggesting they will have less potential to cross the blood-brain barrier, thus reducing any CNS related toxicity. Molecular networking of the crude extracts and the fractions was done through GNPS which allowed the identification of known compounds including one isolated in the present study, Abyssinone V’ 4-methyl-ether (3). Possible derivatives that have not been isolated from this plant before were also putatively identified. , Thesis (MSc) -- Faculty of Science, Chemistry, 2023

- Description: The purpose of this study is to determine whether foreign aid influences the quality of life in South Africa. To do so, the study analyses the relationship between foreign aid and the human development index (HDI). HDI consists of three other indices: the index of wellbeing, the index of education, and the index of income. To measure the relationship between foreign aid and HDI, five Autoregressive Distributed Lag (ARDL) models are used in estimating the effect of foreign aid on HDI as well as life expectancy, education level, unemployment, and GDP per capita from 1993 to 2019. Income, population density, and credit are given to the private sector are part of the empirical models as controlled variables. The results show that no significant relationship exists between foreign aid and HDI, education, and GDP, while aid is linked to a lower life expectancy rate and unemployment. These findings imply that aid can increase the HDI in South Africa by contributing to a decreased unemployment rate, and thus policy makers should establish concrete plans and develop economic strategies that focus on creating incentives that attract more aid, especially in the short run. This can lead to a decrease in the unemployment rate, which is often regarded as South Africa’s biggest economic issue. , Thesis (Ma) -- Faculty of Faculty of Business and Economic Sciences, 2023

- Description: Organisations of the 21st century face a plethora of changes due to globalisation, a world referred to as volatile, uncertain, complex and ambiguous (VUCA). Organisations must consider pertinent stakeholders, specifically employees, and by representation, trade unions, during organisational change attempts. The study has explored the role of trade unions during organisational change in South African organisations. A literature review was conducted, which explored, amongst others, factors driving change, organisational change management models, the labour relations landscape in South Africa and the role of trade unions in organisational change. The empirical study included semi-structured interviews and a survey with a questionnaire. An exploratory sequential mixed methods research design was followed, with semi-structured interviews conducted with trade union representatives and human resource/employment relations managers. Thereafter, an online self-administered survey was conducted focusing on employees. A non-probability judgement design was employed in sampling the participants for the qualitative approach, and five (N = 5) HR/employment relations managers and six (N = 6) trade union representatives were interviewed. Random sampling was employed for the quantitative component and 74 questionnaires were completed. The interviews were thematically analysed while for the survey, exploratory factor and correlation analysis were used. The factor analysis extracted three factors: Before Change; During Change; and After Change. Based on the results recommendations for senior management, HR/ER managers; and for trade unions were presented. The recommendations include that organisations use the framework as a guide to involve trade unions. Trade unions and their representatives need to be acknowledged as important stakeholders before change is introduced. Knowledge of labour law is essential and a culture of open communication must be evident before, during and after change. Trade unions should organise conferences (Indabas) to reorientate and reskill themselves about their role during organisational change within South African organisations. The main contribution of the study is that HR/ER managers and trade union representatives should utilise the framework developed in this study to advance best practices in respect of the role of trade unions in organisational change in the South African context. , Thesis (Ma) --Faculty of Faculty of Business and Economic Sciences, 2023

- Description: The causative agent of African trypanosomiasis, Trypanosoma brucei (T. brucei), has an expanded retinue of specialized heat shock proteins, which have been identified as crucial to the progression of the disease. These play a central role in disease progression and transmission through their involvement in cell-cycle pathways which bring about cell-cycle arrest and differentiation. Hsp70 proteins are essential for the maintenance of proteostasis in the cell. Mitochondrial Hsp70 (mtHsp70) is a highly conserved molecular chaperone required for both the translocation of nuclear encoded proteins across the two mitochondrial membranes and the subsequent folding of proteins in the matrix. The T. brucei genome encodes three copies of mtHsp70 which are 100% identical. MtHsp70 self-aggregates, a property unique to this isoform, and an Hsp70 escort protein (Hep1) is required to maintain the molecular chaperone in a soluble, functional state. This study aimed to compare the solubilizing interaction of Hep1 from T. brucei and Homo sapiens (H. sapien). The recently introduced Alphafold program was used to analyze the structures of mtHsp70 and Hep1 proteins and allowed observations of structures unavailable to other modelling techniques. The GVFEV motif found in the ATPase domain of mtHsp70s interacted with the linker region, resulting in aggregation, the Alphafold models produced indicated that the replacement of the lysine (K) residue within the KTFEV motif of DnaK (prokaryotic Hsp70) with Glycine (G), may abrogate bond formation between the motif and a region between lobe I and II of the ATPase domain. This may facilitate the aggregation reaction of mtHsp70 orthologues and provides a residue of interest for future studies. Both TbHep1 and HsHep1 reduced the thermal aggregation of TbmtHsp70 and mortalin (H. sapien mtHsp70) respectively, however, TbHep1 was ~ 15 % less effective than HsHep1 at higher concentrations (4 uM). TbHep1 itself appeared to be aggregation-prone when under conditions of thermal stress, Alphafold models suggest this may be due to an N-terminal α- helical structure not present in HsHep1. These results indicate that TbHep1 is functionally similar to HsHep1, however, the orthologue may operate in a unique manner which requires further investigation. , Thesis (MSc) -- Faculty of Science, Biotechnology Innovation Centre, 2023

- Description: My thesis explores township life through the eyes of a young boy, Sengwayo, whose life changes when a strange man arrives unexpectedly to stay with his family. The man is introduced as his uncle but nothing further is said about him. Sengwayo soon begins to experience visions and decides to find out who this man really is. His search for truth soon becomes obsessive and culminates in tragedy. As we follow Sengwayo in his quest of uncovering the truth it becomes difficult to differentiate between Sengwayo’s imagination and reality. This thesis collapses the distance between what is and what could be. It does this by alternating short sentences mostly used in the poetry of maskanda lyrics, and in the stream of consciousness found in jazz improvisation. In literary terms, the thesis draws influence from the rants and rhyme schemes of Lesego Rampolokeng, the tone and pace of Sony Labou Tansi and the surrealism in Mangaliso Buzani’s work. , Thesis (MA) -- Faculty of Humanities, School of Languages and Literatures, 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: 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: Immanuel Kant is a key thinker in the History of Western Philosophy whose ideas continue to fascinate contemporary English-speaking academic philosophers. One such idea is Kant's conception of transcendental arguments. Although these arguments do not originate in Kant's philosophy, Kant's conception of them occupies a special place in the English-speaking literature on the topic. A growing trend in this literature is to claim that Kant's transcendental arguments are unique because they aim to achieve an anti-skeptical end through deductive means. I call the basic assumption behind readings of transcendental arguments like these the deductive/anti-skeptical assumption. This assumption claims that deduction is the best means to achieve an anti-skeptical end. In this thesis, I argue that accepting this assumption is one way to misinterpret transcendental arguments because—even though it seems compelling at first blush—it must be false. The resultant twist is that transcendental arguments cannot be deductive, which, in turn, means that understanding that Kant's transcendental arguments are not deductive in nature is itself no small detail for understanding the version of Kant's 'not-deductive' solution to skepticism developed here. , Thesis (MA) -- Faculty of Humanities, Philosophy, 2023

- Description: International literature has tested the effectiveness of translanguaging as a pedagogic tool to enhance learning in a bilingual classroom; however, with the recent curriculum reform and education sector policy, there is no direct claim in the National policy frameworks on the prominence of translanguaging as an effective tool in classroom pedagogy in Namibian schools. This research attempted to investigate the role of translanguaging as a pedagogic tool to enhance learning in the multilingual intermediate English Second Language (ESL) phase as the Language of Learning and Teaching (LoLT) for the intermediate phase, Grades 4-7, in the Erongo Region, Namibia. The study is within the interpretive paradigm and adopts a qualitative methodology using a qualitative multi-case study approach of exploring and understanding differences and similarities between cases. Data collection consisted mainly of open-ended interviews and observations (purposive sampling) of the participating teachers. The research sites and study participants were purposely selected as both schools, diversely located in urban and rural contexts of the region, are enacting the National Language Policy as proposed. This entails using Mother Tongue Instruction (MTI) from Grades 0-3 and then transitioning to English-monolingual instruction from Grades 4 onwards. The study was designed to investigate the role of translanguaging pedagogy in enhancing learning in the Second Language (L2) classroom, without prejudice of social classes - the elite and marginalized communities. It investigated the extent to which teachers’ use of translanguaging pedagogy enhances ESL learning as the LoLT to intermediate phase learners transitioning from MTI to English-only instruction. The main theories underpinning this study are the Vygotskian and Translanguaging theories supported by Krashen and Cummins’ Cognitive Underlying Proficiency (CUP) Model. The outcomes of the study reveal that in both schools translanguaging was supported by content subject teachers and English LoLT teachers and that it positively contributed to improving learner understanding of important concepts in several subjects. However, Mother Tongue (MT) teachers did not support the use of translanguaging and believed that it slowed down the learning of English. , Thesis (MEd) -- Faculty of Education, Institute for the Study of Englishes in Africa, 2023

- Description: The Head of Department (HOD) position at a university has traditionally been viewed as an individual construct. However, due to the demanding nature of such a position, it is not sought-after, as it remains exclusive and unappealing to many academics. Moreover, it is a position that does not encourage inclusive leadership. Tension and role ambiguity are known to arise between the scholarly project on the one hand and management and administrative matters on the other. To address challenges associated with this singular leadership position, an academic department at a South African university adopted a distributed leadership approach in their department as a research experiment. My study was based on this research experiment. I designed this research as an exploratory case study, guided by a socio-cultural conceptualisation of distributed leadership that included a leader-plus and a practice aspect, defined as a product of the interactions of school leaders, followers and their situation. This qualitative case study aimed to describe and explain how a distributed leadership approach was understood and practised in an academic department. It also investigated the enablements and constraints of the approach. Data were generated through document analysis, observation, and individual and focus group interviews. The participants in this study included the departmental leadership team and the department’s academic and administrative staff. Unfortunately, my study took place during the global COVID-19 pandemic and national lockdowns. I had no choice but to adapt my data generation methods due to lockdown restrictions. As a result, most data generation was done via online communication. The study used inductive and abductive analysis to make the data meaningful to the reader. The findings revealed that different participants had different ideas about distributed leadership. Distributed leadership was understood as a socio-cultural practice rather than an individual practice with multiple leaders in relational practice. In addition, this approach was understood as a way of developing and sharing expertise by encouraging teamwork, collegiality and collective decision-making which aligns with the notion of democratic decision-making which creates a platform for the enablement of leadership in others. The study further explored how distributed leadership was practised. The findings were that the HOD position, usually a one-person role, was reconceptualised as a HOD team comprised of three academics and the departmental administrator. The HOD team divided the work among themselves, and this was done according to each individual’s expertise. In addition, leadership within the academic department was not limited to the HOD team but stretched across the department; thus, multiple leaders were evident. Therefore, based on the data, this study discovered that a distributed approach values leadership expertise in others. Consequently, it can be used to promote an inclusive environment in which any organisation member can lead. Inclusivity in the decision-making process was also regarded as a strong practice in the academic department. As a result, this study contends that those in formal positions can develop leadership in others through a distributed leadership approach. Through that, lecturer leadership was enacted through formal faculty and university structures and informally as and when the situation required it. The enablements of this departmental leadership approach included the structural innovation of the Friday check-in as well as the buddy system. These two innovations provided the space for collegiality and the development of voice and leadership. The consultative nature of the HOD team was also viewed as an enablement. Certain factors constrained the distributed leadership approach, one of which was the tension between the hierarchical structure of the university and the more horizontal, distributed leadership approach being piloted in the academic department. In addition to that, another constraint was also very real with the transition to Zoom as an online teaching, learning and supervision platform as a consequence of the COVID-19 pandemic. The final constraint was experienced concerning the department’s history, as it was within a historically White university in South Africa. The effects of this history impacted the departmental culture and, as we know from the literature, institutional culture is extremely difficult to change. Finally, the study concluded that conceptualising distributed leadership as a sociocultural practice with leader-plus and practice aspects provides descriptive language and a solid theoretical and analytical framework for a distributed leadership study. The study makes an important knowledge contribution in the African Higher Education context as limited research has been carried out in this area. Furthermore, in terms of practice, my study serves as a stimulus for leadership discussions that are beneficial to everyone involved in educational institutions as they promote a level of leadership reflexivity, currently absent in many institutions. , Thesis (MEd) -- Faculty of Education, Secondary and Post-School Education, 2023

- Description: Climate change is predicted to displace thousands of people across the globe. Due to their geographical location and limited resources available for adaptation, this will particularly impact those in developing states, who might have to flee from the growing frequency and severity of rising sea levels, drought and desertification, and acute natural disasters such as floods, wildfires, and hurricanes. This is likely to have pervasive effects on the moral interests of those affected, threatening loss of life, the deterioration of livelihoods, and for small island states even complete or substantial loss of state territory. In this thesis I will argue that we should conceive of this situation as a problem of global justice. Though some argue that questions of justice only arise within the state, I will argue that global economic and political institutions have contributed to the plight of climate migrants, and that following from Darrel Moellendorf’s theory of associational justice, this enduring impact results in an association and duties of justice that transcend state borders. To respect the dignity of climate migrants, such an unjust association needs to be rectified by establishing ethical principles that could be reasonably endorsed by everyone affected. Drawing from Gillian Brock, I will argue that the best way to rectify the situation is through establishing a principle of distributive justice which focuses on ‘agency needs’: needs whose fulfilment is necessary for human agency. Using this framework, I then provide some recommendations of what is owed to climate migrants to achieve justice for them. I also consider how these duties of justice should be distributed, first critiquing a dominant approach that attributes duties primarily to polluters. In the end, I recommend that duties should be dispersed between all those who support the global institutions responsible, those who have been high polluters since 1990, and the most affluent in the world. As the effects of climate change become increasingly pronounced within the next fifty years, establishing what is owed to those displaced is of utmost importance, and I hope this thesis shows how normative philosophy can help us think through these urgent questions. , Thesis (MA) -- Faculty of Humanities, Philosophy, 2022

- Description: This study examines educational governance in schools for internally displaced learners in Puntland, Somalia. Many Somalis have been internally displaced from the south and central of Somalia and neighbouring regions because of armed insurgence, as well as climate and ecological disasters. Communities of internally displaced Somalis who have settled in the north-eastern region of Somalia, together with the Ministry of Education and nongovernmental organisations such as Relief International, have established schools for internally displaced learners. The study uses interviews with teachers, school principals and school committee members to examine their experiences of how schools are governed, specifically in terms of the bottom-up and top-down approaches to peacebuilding education. This research study is the first of its kind to examine the experiences of education actors in internally displaced person schools in Somalia. It provides crucial, new information on northern NGOs and how they shape the governance of knowledge and resources in Somali schools and how Somali education actors interpret and respond to these interventions. Drawing on education studies and international relations, it develops a transdisciplinary framing of peacebuilding education and specifically focuses on the top-down and bottom-up approaches to peacebuilding education provision. It weaves these two disciplinary perspectives together to help establish the implications of the security sector in education and broadly post-conflict reconstruction. The study finds that donors, international NGOs and government actors use a top-down approach to education, which may sit at odds with local needs and priorities. It finds that Somali knowledge and values are marginalised in the curriculum and teachers’ professional development and that the distribution of resources such as teacher salaries and school feeding programmes is fragmented, opaque and lacking in accountability. The study emphasises that the exclusion of local voices may further contribute to the causes underlying conflict. , Thesis (MA) -- Faculty of Humanities, Political and International Studies, 2022

- Description: Dans un couple, la négociation de l’espace domestique est contesté. Dans le conte « La Barbe Bleue » (1697) de Charles Perrault, cette négociation de l’espace est particulièrement dangereuse. Le mari a un espace privé à lui, interdite à sa femme, dans lequel il cache un secret sinistre : il a tué toutes les épouses précédentes. L’existence de cette pièce menace l’équilibre du foyer, mettant en question le droit à un espace privé, et révélant le danger de garder un secret quand on vit en couple. Quand l’épouse franchit le seuil de la pièce interdite, son mari se met en colère et s’apprête à la tuer. Il s’ensuit une lutte acharnée entre homme et femme, devenus adversaires. Puisque la chambre interdite joue un rôle capital dans ce récit, cela suggère que les éléments spatiaux jouent un rôle significatif au sein du couple. Alors, on vise à analyser le cadre domestique et son rôle dans le rapport entre les personnages. Avant leur mariage, l’épouse avait déjà une idée que Barbe Bleue n’était pas honorable, ce qui remet en question sa décision d’épouser cet homme. Au même temps, on se demande pourquoi l’époux aurait tué toutes les épouses précédentes. Cela incite le lecteur à chercher à mieux comprendre les personnages. A cette fin, on vise à considérer les personnages comme des espaces, eux aussi, ce qui permettra une analyse approfondie de leur caractère et de leurs rapports personnels. Nous ferons la comparaison du conte perraultien avec les versions contemporaines de notre époque de Tahar Ben Jelloun et d’Amélie Nothomb. Dans la version jellounienne, l’intrigue se déroule dans un cadre musulman et maghrébin, tandis que le récit nothombien se situe à Paris. Ces ouvrages présentent donc des perspectives neuves sur Barbe Bleue et sa dernière épouse, et sur le cadre dans lequel ils se trouvent. , For a couple, negotiating the spatial dynamics of their home can be a challenging feat. In the story of “Bluebeard” (1697) by Charles Perrault, this negotiation is presented in an even more grim light. The husband sets aside a private room for himself, off-limits to his wife, in which he conceals a deadly secret, that he has murdered his previous wives. The very existence of this forbidden chamber threatens the stability of the household and raises the question about whether secret unshared spaces between partners are tenable, and indeed whether spouses have the right to keep secrets. When the wife enters this forbidden room and discovers the corpses of his previous wives she provokes the anger of her husband, who then attempts to kill her as punishment. A fierce struggle ensues between husband and wife, who have now become adversaries. Because the forbidden chamber plays a key role in this story, this tells us that space is very important to the relationship between the couple. Thus, we intend to explore the domestic sphere and its role in the relationship between the characters. Prior to their marriage, the wife already has an indication as to her husband’s dubious character, which calls into question her decision to marry him. We also wonder why Bluebeard might have murdered his previous wives. To understand them better, the characters will be considered as spaces, an approach which has the potential to offer a deeper and more holistic analysis of their characters and their personal relationships. We will be comparing Perrault’s tale to two revisions by Tahar Ben Jelloun and Amélie Nothomb, which place the story into different contexts: the Islamic world and modern-day Paris respectively. These two revisions provide interesting and new perspectives on the couple in the domestic space and the ways in which the characters are represented. , Thesis (MA) -- Faculty of Humanities, School of Languages and Literatures, 2023
