  • Description: The Big Mac Index was developed in 1986 by The Economist magazine as a playful take on the Purchasing Power Parity theory. Its purpose is to indicate whether a currency is overpriced or undervalued in relation to the real exchange rate and whether it can be used as a reliable indicator of exchange rate predictions. There are two versions of the Big Mac Index: the raw Big Mac Index and the adjusted Big Mac Index. If appropriate, this index might be developed into an economic theory that can be applied to corporate finance, international trade, and international finance. To determine which Big Mac Index measure is a better indicator of exchange rate valuation, a comparison analysis was conducted. This study set out to determine how well the adjusted Big Mac Index performed as a gauge for exchange rate valuation. The research then compares the two Big Mac Index measures' ability to anticipate future exchange rates in order to determine which is more accurate. Data from the South African Reserve Bank and The Economist databases covering 37 nations from 2000 to 2022 were used for the analysis. Exchange rate misalignment trends were assessed globally, and the results indicated that the adjusted BMI was a more accurate measure of purchasing power. Tests of correlation revealed that there was a positive association between the real exchange rate and the Big Mac Index. Findings from a panel ARDL Model indicated that taking into consideration country-specific GDP variations and group heterogeneity can enhance the real exchange rates' ability to predict the raw BMI. The research also focused on the South African Rand to ascertain whether the Big Mac Index validates the Purchasing Power Parity theoretical framework. Using cointegration tests and graphic analysis, it was possible to find evidence for a cointegrating relationship between the real exchange rate and the Big Mac Index measures during the last 20 years. Additionally, a positive correlation between the modified Big Mac Index and terms of trade was discovered in the results, confirming the hypothesis that the Big Mac Index satisfies current account assumptions. Finally, a VEC model demonstrated that the modified BMI outperforms the raw BMI in terms of forecasting estimates. Overall, the study found that the Big Mac Index is more than a bit of fun as per its origin. The results showed that the adjusted Big Mac Index has practical applications and the potential to be considered as an economic theory. , Thesis (MCom) -- Faculty of Commerce, Economics and Economic History, 2024

  • Description: I am a ceramic sculptor. I make use of clay that I have sourced from Joza, the Makhanda location, and Cofimvaba in a rural area called Magwala. I process this clay and then use it to create a visual and tangible representation of the anxiety I experience as a queer black woman living in South Africa. Unongayindoda is a word that has been used by isiXhosa speaking people in my village to call me ever since I was a child. This is a word that I have chosen to own, in much the same way that some people have chosen to own the word “queer.” My experience of being unongayindoda has had an impact on my mental health, and the process of digging clay, processing it for use and then using it to create my work has become very therapeutic for me. My work’s primary aim is to explore the use of clay as a representative embodiment of anxiety in my work as a rural black queer sculptor who identifies as unongayindoda. The thesis component of my work is a qualitative study informed by autoethnography, practice and art-based research. , Thesis (MA) -- Faculty of Humanities, Fine Art, 2024

  • Description: Globally, agriculture is an essential part of people’s livelihoods, contributing to rural economies and food security. However, cultivated land abandonment, the intentional or unintentional cessation of agricultural activities for takeover by other land uses, is becoming increasingly common. Although widely studied, the outcomes of cultivated land abandonment are highly context-dependent and varied. Understanding this phenomenon would thus benefit from placed-based social-ecological case study perspectives, particularly in more understudied contexts. This study represents such a perspective, taking a social-ecological approach to understand how land abandonment has emerged and what its consequences are for the desired future outcomes in the Hlankomo and Lower Tsitsana villages in the Tsitsa River catchment. Drawing on McGinnis & Ostrom’s (2009) framework, I framed cultivated land abandonment in my study area as a “focal action situation” informed by the interaction of natural resource systems, governance systems, actors, and resource units. To better understand the current state of the natural resource system and important ecological (resource) units (grass), I used two measures of ecological condition: a rapid assessment test that provided a broad, if superficial, understanding of degradation and land condition, and a veld condition assessment that provided an understanding of grassland composition and quality in abandoned fields. I also used aerial photographs to assess the extent of changes in abandoned cultivation in the catchment. To understand actors, governance systems, how they interacted with natural resource systems and units for land abandonment to emerge, and what implications these interactions may have for the future of these lands, I used semi-structured interviews. The Rapid Assessment Test tool showed that the abandoned cultivated fields were dominated by grasses (58.3%), while shrubs (11%) and succulents (11%) were the least prevalent. The veld assessment identified sixteen grass species in both villages, with Aristida junciformis (23%) and Eragrostis plana (22.2 %) being the most dominant. The grazing statuses of the grasses showed that there were more Increaser II species, followed by Increaser III, Exotic, Increaser I and Decreaser species, respectively. There were more grass species with low grazing and average grazing values than grass species with high grazing values. The Rapid Assessment tool and the Veld assessment showed that the fields were dominated by poor grass species that grow on degraded lands. The results thus showed that the abandoned cultivated lands are degraded and in poor condition, as they are covered mainly by poor grass species that are dominant in over-utilised and overgrazed areas. The aerial photographs showed a decline in cultivated lands from 1966 to 2015, with a significant decline between 1966 and 2003. The land under cultivation between 1966 and 2003 decreased by 95 %, resulting in an annual decline of 2.56 %. The land under cultivation from 2003 and 2015 decreased by 60 %, resulting in a decline of 4 % per year. Local people corroborated the increase in cultivated land abandonment in the interviews, and this is why I attempt to understand why abandoned cultivated land happened (how the resource system and governance systems/actors interacted to shape cultivated land abandonment). As in other South African rural contexts, reasons people gave for land cultivation abandonment revealed the strongly intertwined nature of ecological and social systems, including no fence, livestock eating crops, no cattle, lack of labour, migration, lack of resources (money and equipment), parents passing on, expensive fertilizers, rainfall variability, dependency on grants, lack of interest and laziness. People had different views about the future of the abandoned cultivated lands, suggesting building homes, recreational parks, poultry farms, and recultivating and livestock protection camps, while others indicated that they didn’t care what happens to the abandoned fields. Many people still value abandoned lands and would prefer for the land to be recultivated, but they are held back by factors beyond their control, such as no fencing and a lack of governmental support in the form of fertilisers and machinery for ploughing. Additionally, our ecological results suggest that, due to the degraded states of these lands, significant rehabilitation would be required to realize these desired outcomes. Overall, this study shows the social-ecological complexity that drives cultivated land abandonment in the Tsitsa River catchment, providing a context-specific understanding of the drivers and consequences of abandoned cultivated land, future options more specific to these villages, and the broader Tsitsa catchment. At the same time, my study also corroborates similar studies in rural African and other global South contexts, thus supporting generalizable knowledge that can be used in the development of agrarian, social and environmental policies in these regions. , Thesis (MSc) -- Faculty of Science, Environmental Science, 2024

  • 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

  • Description: This study empirically examined the interconnection among bank competition, regulation and stability of eighteen Zimbabwean banks during the period 2011-2017. Zscore, Capital Adequacy Ratio (CAD), and Loans market share and Deposits market share which are proxies for stability, regulation and competition respectively were examined firstly using the Panel Vector Autoregressive (PVAR) model. Model 1 used loans market share as a proxy for competition and model 2 used deposits market share instead. The stability test using Eigenvalue Stability Condition showed that the PVAR model is unstable. Secondly, the above variables and five bank specific variables (i.e., credit risk, management efficiency, liquidity, return on assets and bank size) were estimated using the Feasible Generalised Least Squares (FGLS) model. The study documents that competition positively contributed to stability and regulation negatively influenced the stability of the Zimbabwean banks. Meanwhile, bank size and credit risk have a negative relationship with stability; management efficiency and liquidity have a positive relationship. Return On Assets has a negative and positive relationship with stability in model 1 and model 2, respectively. The findings implied that to enhance stability, banks must experience a competitive environment, reasonably low minimum capital requirements and cautiously designed regulatory frameworks. , Thesis (MCom) -- Faculty of Commerce, Economics and Economic History, 2023

  • Description: This study considers the experiences of teachers working with Fetal Alcohol Spectrum Disorders (FASD)-affected children in mainstream schooling. FASD refers to a range of conditions in children resulting from maternal alcohol consumption during pregnancy. Prevalence rates in South Africa are said to be among the highest in the world. There is a paucity of research on FASD-affected children in the Eastern Cape. This study was thus conducted in the Buffalo City Metropolitan Municipality (BCMM). Teachers told stories of their experiences of teaching undiagnosed FASD-affected children in mainstream schooling. The stories reveal the quality of life for children in classrooms and socio-contextual influences of their experiences at school, as well as the responsibilisation of teachers in these settings. This qualitative research is situated within a social constructionism paradigm. The social model of disability was utilised as a theoretical framework for this study to represent the systemic barriers against which FASD-affected learner support in the mainstream school can be conceptualised. A sample of five (5) Black female teachers were interviewed. Data gathering was done by conducting telephonic interviews using the single question inducing narrative, known as SQUIN. A thematic analysis of the data was conducted for the purpose of identifying themes within the data collected. Four superordinate themes emerged from the data, viz. narratives of FASD-affected learners, narratives of parental involvement, narratives of the role of teachers and narratives of stakeholder support. This study reveals a significant level of responsibilisation of teachers. Teachers appear to play a bigger role than just being teachers and they positioned themselves as playing a parental role in relation to FASD-affected learners. FASD-affected learners were positioned as “the problem” in the mainstream classroom whereas the environment is a disabling factor to FASD-affected learners. There is a need for a holistic approach in working with FASD-affected learners from all relevant stakeholders. Key recommendations are made for effective inclusion of FASD-affected learners in mainstream schooling. Future research recommendations include repeating this study in a different geographical area, a focus on senior phase learners and/or a more diverse sample. The findings assist in the development of policies of inclusive education in mainstream schooling and supportive strategies to enhance the developmental trajectory of FASD-affected children. , Thesis (MA) -- Faculty of Humanities, Psychology, 2022

  • Description: This thesis centres itself around an investigation into the representations of the relationship between intimacies and ideas of romance, love, desire, and vulnerability in male relationships. The premise for this body of work was sparked by my own observations on the conflation of sex and intimacy in representations of queer male love—particularly (but not exclusively) in mainstream film and media. Whilst intimacy and sex are not unrelated, the over-emphasis on the physical when trying to represent the connection between two men led me to consider other ways in which a relationship or special connection could be gestured towards — through other kinds of signifiers that last longer than physical contact and point to the importance of a particular connection. In the introduction, I consider my own experiences as a closeted queer teen when contemplating representations of queer relationships in mainstream media. I explore several studies by gender and film theorists who consider reasons and modes in which the representations of queer intimacies on-screen are distorted to favour a presumed heterosexual audience. In the first chapter, I discuss two potential means by which to relay a more complex emotional state via the use of narrative signifiers. I examine T.S. Eliot's (1919) theory on the objective correlative in narratives as a means to explore the emotional state of a character through metaphors which open up the reading rather than illustrating it through dialogue or direct speech. I then explore Susan Stewart's (1992) ideas on souvenirs of personal experience. In Chapter Two, I conduct a close reading of three mainstream films, which employ such signifiers in the attempt to share more complex representations of queer male intimacies through well-developed storylines and characters. The films Brokeback Mountain (2006), Moonlight (2016), and Call Me by Your Name (2017) have been selected based on their use of the objective correlative and souvenirs as plot devices (rather than exclusively physical intimacy) to demonstrate the emotional resonance between characters. The third and final chapter explores my own use of objective correlatives and souvenirs as symbolic, narrative devices in my practical body of work: an online garden of remembrance. My practical work focuses largely on the process of creation of these intimacy objects (the objective correlative or the souvenir) through an investigation into my own poetry, which details my experiences of intimacies with other men, specifically where vulnerability and secrecy played a large role. , Thesis (MFA) -- Faculty of Humanities, Fine Arts, 2022
