- Description: The application of traditional manual techniques for fish detection and classification faces significant challenges, primarily stemming from their labour-intensive nature and limited scalability. Automating these kinds of processes through computer vision practices and machine learning techniques has emerged as a potential solution in recent years. With the development of and increase in ease of access to new technology in recent years, the use of a deep learning object detector known as YOLO (You Only Look Once) in the detection and classification of fish has steadily become notably popular. This thesis thus explores suitable YOLO architectures for detecting and classifying fish. The YOLOv5 and YOLOv8 models were evaluated explicitly for detecting and classifying fish in underwater environments. The selection of these models was based on a literature review highlighting their success in similar applications but remains largely understudied in underwater environments. Therefore, the effectiveness of these models was evaluated through comprehensive experimentation on collected and publicly available underwater fish datasets. In collaboration with the South African Institute of Biodiversity (SAIAB), five datasets were collected and manually annotated for labels for supervised machine learning. Moreover, two publicly available datasets were sourced for comparison to the literature. Furthermore, after determining that the smallest YOLO architectures are better suited to these imbalanced datasets, hyperparameter tuning tailored the models to the characteristics of the various underwater environments used in the research. The popular DeepFish dataset was evaluated to establish a baseline and feasibility of these models in the understudied domain. The results demonstrated high detection accuracy for both YOLOv5 and YOLOv8. However, YOLOv8 outperformed YOLOv5, achieving 97.43% accuracy compared to 94.53%. After experiments on seven datasets, trends revealed YOLOv8’s enhanced generalisation accuracy due to architectural improvements, particularly in detecting smaller fish. Overall, YOLOv8 demonstrated that it is the better fish detection and classification model on diverse data. , Thesis (MSc) -- Faculty of Science, Computer Science, 2024

- Description: Various science curricula including that of Namibia recommend that teaching and learning should start with the knowledge and experiences of learners from their homes and communities. These experiences are the learners’ Indigenous Knowledge (IK) which should be integrated to make science accessible and relevant to learners from diverse sociocultural backgrounds. This suggests that science teachers are encouraged to integrate IK into their teaching to help learners grasp abstract concepts and construct their own understanding of phenomena. However, much literature has revealed that many teachers find it difficult to integrate IK into their science teaching. Some scholars further argue that teachers lack the pedagogical content knowledge to effectively integrate IK. I assume this could be because the science curriculum is not explicit on how IK should be integrated into science teaching. It is against this backdrop that in this study I mobilised the Indigenous technologies of making oshikundu and preserving ombidi to support Grade 10 Biology learners in talking and making sense of diffusion and osmosis. This study was underpinned by the interpretivist and Indigenous research paradigms. Within the Indigenous research paradigm, I focused on Ubuntu as a perspective. A qualitative case study was employed and conducted at a certain school in the northern part of Namibia, in the Ohangwena region. I worked with a group of 35 Grade 10 learners, two Indigenous Knowledge Custodians (KCs) who are the custodians of cultural heritage and one Biology teacher (critical friend) as participants in this study. Qualitative data were collected using a focus group interview (sharing circle), group activity, participatory observation, and learners’ journal reflections. Vygotsky’s sociocultural theory together with Ogunniyi’s Contiguity Argumentative Theory were used as lenses to analyse data. The findings of the study revealed that during the IKCs’ practical demonstrations learners were able to identify science concepts embedded in the cultural practices of making oshikundu and preserving ombidi. The findings further revealed that the practical demonstrations enhanced active participation and interactions among learners. I thus recommend that teachers should tap into IKCs’ cultural heritage by inviting them into their classrooms to make science relevant, accessible and meaningful to learners. , Thesis (MEd) -- Faculty of Education, Secondary and Post-School Education, 2024

- Description: The development and implementation of extreme value theory models has been very significant as they demonstrate an application of statistics that is very much needed in the analysis of extreme events in a wide range of industries, and more recently the cryptocurrency industry. The crypto industry is booming as the phenomenon of cryptocurrencies is spreading worldwide and constantly drawing the attention of investors, the media, as well as financial institutions. Cryptocurrencies are highly volatile assets whose price fluctuations continually lead to the loss of millions in a variety of currencies in the market. In this thesis, the extreme behaviour in the tail of the distribution of returns of Bitcoin will be examined. High-frequency Bitcoin data spanning periods before as well as after the COVID-19 pandemic will be utilised. The Peaks-over-Threshold method will be used to build models based on the generalised Pareto distribution, and both positive returns and negative returns will be modelled. Several techniques to select appropriate thresholds for the models are explored and the goodness-offit of the models assessed to determine the extent to which extreme value theory can model Bitcoin returns sufficiently. The analysis is extended and performed on Bitcoin data from a different crypto exchange to ensure model robustness is achieved. Using Bivariate extreme value theory, a Gumbel copula is fitted by the method of maximum likelihood with censored data to model the dynamic relationship between Bitcoin returns and trading volumes at the extreme tails. The extreme dependence and correlation structures will be analysed using tail dependence coefficients and the related extreme correlation coefficients. All computations are executed in R and the results are recorded in tabular and graphical formats. Tail-related measures of risk, namely Value-at-Risk and Expected Shortfall, are estimated from the extreme value models. Backtesting procedures are performed on the results from the risk models. A comparison between the negative returns of Bitcoin and those of Gold is carried out to determine which is the less risky asset to invest in during extreme market conditions. Extreme risk is calculated using the same extreme value approach and the results show that Bitcoin is riskier than Gold. , Thesis (MSc) -- Faculty of Science, Statistics, 2024

- Description: The Curriculum and Assessment Policy Statement (CAPS) for Physical sciences in South African states that learners should carryout formal experiments Formal experiments contribute immensely to the development of laboratory skills and scientific knowledge, as well as understanding science concepts and theories. However, research shows that many teachers do not support and/or guide learners in formal experiments. The aim of this study was to explore and understand the attitude of Grade 11 Physical sciences teachers in Buffalo City Metropolitan District (BCM), in the Eastern Cape province regarding formal experiments. The TALIS framework was used to unpack teachers’ perceptions and understanding of formal experiments and related practical activities. A qualitative approach within the interpretative paradigm was employed in which an open-ended questionnaire and face to face interviews were conducted as data collection tools. The sample comprised ten participants (4 males and 6 females) of ages ranging from 20 to 54 years The data collection process involved three phases that included a pre-intervention questionnaire, an intervention workshop and post intervention face to face interview. Most of the participants 7(70%) confirmed that they did not carry out all formal experiments as prescribed in the CAPS document. The results revealed that most teachers do not understand the purpose of practical work and /or formal experiments, which is a possible explanation for the negative attitude towards the formal experiments teachers hold. The study also revealed that some participants 4(40%) did not understand the link between science pedagogy and the nature of science. It was discovered from the results that negative attitude towards formal experiments was due to lack of resources, lack of knowledge to guide learners to carry out the experiments, lack of time, and overcrowded classes. , Thesis (MEd) -- Faculty of Education, School of Postgraduate Education, 2024

- Description: Offshore benthic ecosystems (> 200 m depth) are challenging to access and remain poorly studied globally. Epifaunal invertebrates comprise a critical trophic level in benthic ecosystems and can serve as indicators of the overall health and functioning. There is limited knowledge of South Africa’s offshore marine environment and benthic ecosystem functioning due to limitations in funding, resources, and the lack of suitable science-based monitoring tools which are vital for sustainable management into the future. The aim of this research was to improve the understanding of epifaunal functioning as well as their potential physical drivers in 13 South African offshore biogeographic ecotypes. The objectives of this study were threefold: 1) to investigate the functional composition of benthic epifauna from 13 biogeographic ecotypes, 2) to quantify the Functional Diversity (FD) associated with epifaunal traits between the different assemblages (i.e. biogeographic ecotypes), and 3) to evaluate the relationship between physical variables and epifaunal functional traits at the biogeographic ecotype level. Biological trait-based approaches were applied to a subset of 80 benthic epifaunal species collected from 909 offshore stations along the west and south coasts of South Africa. Nine biological traits (associated with life history, morphology and behavioural characteristics exhibited by each species) were classified into 39 modalities and weighted with biomass. Community Weighted Means (CWMs) were used to evaluate the benthic epifaunal functional trait composition of the 13 biogeographic ecotypes. Functional composition across the 13 ecotype assemblages on the west and south coast appeared to be dominated by species with similar trait compositions, such as large, long-lived, surface crawling/burrowing/filter-feeding epifauna with medium to no mobility, however, their percentage of contribution to trait expression (CWMs) was higher on the west coast. Functional diversity indices (alpha and beta) showed higher overall FD for west coast ecotypes, with most ecotypes on the continental shelf (except slopes and canyons) being significantly different (p<0.05) from ecotypes on the south coast. The global RLQ (three-table co-inertia) test did not reveal a significant relationship between biomass and physical variables or between biomass and traits (p>0.05). The fourth-corner method was used to test the significance of individual traitenvironment relationships. The fourth-corner results were similar overall to the RLQ analysis, revealing that three physical variables (temperature, depth, and fluorescence) were significantly correlated to two trait modalities belonging to the feeding mode filter-feeders (FM1) and scavengers (FM5). Scavengers were positively correlated with depth and negatively with temperature, while filter-feeders were positively correlated with fluorescence levels. This indicated that the presence of scavenging epifauna increased with a decrease in temperature and an increase in depth. While a positive significant correlation between filter-feeders and fluorescence suggested their potential tolerance or preference for environmental conditions with high levels of fluorescence. This research was the first such study to explore the functional composition and diversity of benthic epifauna and their relationship with potential physical drivers in offshore west and south coast benthic biogeographic ecotypes of South Africa. The application of new tools to quantify the functional diversity of epifauna as indicators of ecosystem health, and their potential physical drivers. This provided a platform on which to advance our understanding of benthic communities and the roles they play in ecosystem functioning under changing environments. Functional trait-based approaches such as those applied in this study can provide us with vital information on the relationship between biodiversity, ecosystem functioning, and physical drivers. Environmental stressors and changing climate patterns threaten to impact marine ecosystems and their functioning. Benthic epifauna are especially sensitive to changes in their environment and these fluctuations could potentially lead to the loss of certain benthic functionality, altering the thresholds these ecosystems have to response to disturbances. This undermines the stability of these ecosystems which can have ripple effects on the health of these ecosystems and their ability to provide the ecosystem services humans dependent on. Having suitable tools to track current and predict future changes will therefore be vital to inform management and conservation strategies for sustainable ocean utilisation. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2023

- Description: This research study focuses on nurses’ experiences of participating in an abortion counselling training programme in the Eastern Cape Province (E.C), using a grounded theory and symbolic interactionism framework. The study aims to investigate how participating in a women-centred abortion counselling training course offered through the Critical Studies in Sexualities and Reproduction research unit may modify or improve nurses’ practice of abortion counselling and understanding of quality abortion services. Through purposive sampling, nine research participants working as abortion providers in EC health care facilities were recruited. Research data were produced using discussions around prior abortion counselling experiences, a reflective activity, power point case presentations conducted within the counselling training, and semi-structured interviews conducted two months after the training with five of the providers. A grounded theory analysis was used to generate themes that highlighted different aspects that enabled or hindered access to quality abortion services. In accordance with prior research, it was revealed that nurses undergo abortion training but there is limited content on abortion counselling training. Findings from this study reveal the modifications of practice and understanding of quality abortion services of nurses who participated in the client-centred abortion counselling training course. Themes of change that emerged from the nurses’ experiences were rendering counselling services in a non- judgemental, non-directive way, being acknowledged and recognized for the services they offer as abortion providers, and accepting that abortion is a reproductive legal right that can be accessed whenever a woman in need of the service requests it. The findings of this research also indicate that, despite the controversy and stigma attached to providing abortion services, the participants were motivated to continue offering abortion services because they felt equipped since undergoing abortion counselling training. The training course improved reported abortion counselling practices, but systematic issues such as lack of managerial support, space for individual counselling and procedure equipment continue to undermine services. , Thesis (MA) -- Faculty of Humanities, Psychology, 2023

- Description: Non-Timber Forest Products (NTFPs) are wild biological resources obtained from natural landscapes, agricultural systems, and rural and urban regions for a variety of uses. NTFPs contribute significantly to livelihoods and living standards by offering a variety of socioeconomic benefits such as food, health, income generation, and safety nets. These multiple benefits are provided by a wide diversity of plant, animal and fungal species in different settings. However, the precise number of NTFP species used depends on the scale of assessment, namely use by individuals, by households and by villages. Consequently, it is difficult to compare numbers of species used between studies because of the differing scales. As a result, the objective of this study was to determine the number of NTFP species used at three different scales and how each is correlated with appropriate scale-dependent contextual variables. This objective was met by sampling individuals and whole households in five villages in the Vhembe District in Limpopo Province, South Africa. Twenty households were randomly selected in each village, providing a total sample of 100 households and 179 individuals in those households. In each household, every adult member was interviewed individually about the NTFPs that they used or knew. The major questions covered the NTFP species used, the respondents' socioeconomic level, the NTFP species used previously, and if the number of NTFP species are changing in the landscape. Data were reported per individual as well as per household and per village. The household level was derived by adding the responses of all the adults in each household but excluding duplicates. The same approach was used at the village scale, namely, the data across the 20 households were pooled, and duplicates were omitted. Patterns of NTFP use were examined by type of NTFP, and analysis using standard statistical tests, along with a Principal Components Analysis and a multivariate Detrended Correspondence Analysis of the NTFP species composition across villages. A total of 275 species of NTFPs were mentioned across the entire sample, including 81 species of firewood, 48 species of edible insects, 43 species of wild vegetables, 40 species of edible fruits, 38 species of wood utensils, 28 species of medicinal plants, 23 species of thatch grass, 19 species of poles, 19 species of wood for carvings, nine species of reeds, eight species of mushroom, and eight species of fodder. Of these species, some species had more than one use. Approximately 90% of the species used by the respondents were native species. Wild vegetables (e.g., Corchorus olitorius, Amaranthus capensis, Bidens pilosa), firewood (e.g., Colophospermum mopane, Parinari curatellifolia, Combretum hereroense), wild fruit (e.g., Landolphia kirkii, Vangueria infausta), and edible insects (e.g., Imbrasia belina, Macrotermes michaelseni, Encosternum delegorguei) were the most often used NTFPs by communities in the Vhembe area. Most of the households relied on NTFPs for subsistence. At the scale of an individual, the mean number of NTFP species used was 26.8±12.6 across the five villages. When considering a household, the mean number was 36.1±10.7 species. When aggregated across the 20 households per village, the mean number per village was 105.2±34.1 species. The species accumulation curve showed that 20 households per village were reasonably representative for four of the five villages. The results from the principal component analysis (PCA) and correlation analysis revealed that age, education, and employment status were significantly associated with the number of species used by individuals, whereas gender showed no clear correlation. At the household scale, household size was positively related with the number of species used, but income level and income source were not. At the village scale, attributes such as proximity to a town, settlement type, vegetation type, and distance to a nearby savanna all had some influence on the number of NTFP species listed. Most of the respondents felt that the number of species used had increased over the last 10–15 years, although some stated the opposite. Increases were attributed by traditional councils bans, the establishment of protected areas, and restoration. Activities eroding the number of NTFP species were identified as clear felling for farming, climate change, and over-harvesting. This study suggests that communities must be made more aware of the overharvesting of NTFP species in the savanna to avoid biodiversity loss. , Thesis (MSc) -- Faculty of Science, Environmental Science, 2023

- Description: Non-Timber Forest Products (NTFPs) are wild biological resources obtained from natural landscapes, agricultural systems, and rural and urban regions for a variety of uses. NTFPs contribute significantly to livelihoods and living standards by offering a variety of socioeconomic benefits such as food, health, income generation, and safety nets. These multiple benefits are provided by a wide diversity of plant, animal and fungal species in different settings. However, the precise number of NTFP species used depends on the scale of assessment, namely use by individuals, by households and by villages. Consequently, it is difficult to compare numbers of species used between studies because of the differing scales. As a result, the objective of this study was to determine the number of NTFP species used at three different scales and how each is correlated with appropriate scale-dependent contextual variables. This objective was met by sampling individuals and whole households in five villages in the Vhembe District in Limpopo Province, South Africa. Twenty households were randomly selected in each village, providing a total sample of 100 households and 179 individuals in those households. In each household, every adult member was interviewed individually about the NTFPs that they used or knew. The major questions covered the NTFP species used, the respondents' socioeconomic level, the NTFP species used previously, and if the number of NTFP species are changing in the landscape. Data were reported per individual as well as per household and per village. The household level was derived by adding the responses of all the adults in each household but excluding duplicates. The same approach was used at the village scale, namely, the data across the 20 households were pooled, and duplicates were omitted.

- Description: Job performance and professional commitment are potent drivers of organisational efficiency and overall organisational prosperity, respectively. The severe lack in research regarding these constructs in relation to the pharmaceutical industry or to pharmacists specifically, provided the prime opportunity for the present research to fill this gap. The aim of the present research was therefore to determine the factors influencing professional commitment and job performance in pharmacists in Nelson Mandela Bay, given the Covid-119 environment. A quantitative research approach was adopted for the present study and involved the distribution of a likert—scale questionnaire measuring the dependent variables – professional commitment and job performance and the independent variables – work stress, job commitment, self-esteem and emotional intelligence. A total of 142 surveys were analysed, signalling a response rate of 94.6 67 %. The key findings of the statical analysis show that work stress is negatively related to affective professional commitment and job performance. Job commitment was positively related to job performance and affective professional commitment and self-esteem have a directly positive effect on affective professional commitment. Social skills and self-motivation (as components of emotional intelligence) had a positive relationship with job performance and professional commitment, respectively. Based on these findings, several managerial implications and recommendations were offered. , Thesis (MBA) -- Faculty of Business and Economic Sciences, 2022

- Description: The foundations of African feminisms are intertwined with the historical liberation of the African continent. Joice Mujuru’s five decades in Zimbabwean political parties are no different in showing the gendered nature of the fight against the intersectional oppressions of nation, race, class and gender. The research aimed to examine the political life of Joice Mujuru between 1973 and 2018 in various political roles and what this might mean for how women political leaders participate and make decisions as autonomous individuals within political parties in Zimbabwe. This study is a political biography of Joice Mujuru’s ideas and leadership in political parties in Zimbabwe since 1973, when she joined the Zimbabwe African National Union – Patriotic Front (ZANU-PF) as a guerilla of its military wing, the Zimbabwe African National Liberation Army (ZANLA). Mujuru was the only woman in the first ZANU-PF cabinet in 1980. She served the Zimbabwean government in different cabinet positions and became the first female vice-president in 2004, until her ousting in 2014. This study is based on an interview with Mujuru, and nine interviews with one Member of Parliament, two independent political party candidates, three academics, two CSO activists, the leader of LEAD political party in Zimbabwe and personal communication with a celebrated Zimbabwean writer. The study uses the concept of “patriarchal bargain” (Kandiyoti, 1988; Makhunga, 2016) and “femocracy” (Mama, 1995b) to show that Mujuru’s participation in political parties has been shaped by compromising and negotiating a complex web of patriarchal constraints for acceptance and respect. This study shows that wifehood and motherhood, the idea of musha mukadzi (‘woman as home’), stands out as a defining factor for Mujuru in her identity formation as a political party leader and how she views the roles of other women in Zimbabwean political parties and politics. I term this political identity maternal dignity, which is a collective set of ideas of maternal respect determining women’s participation in political parties. The study shows that Mujuru uses dominant ideas of maternal dignity as a tool of self-presentation and self-preservation to survive as a political leader. Mujuru’s expulsion from ZANU-PF and her subsequent leadership in other political parties demonstrates the ways in which maternal dignity limits women from shaping alternative ideas of leadership outside of respectable womanhood. Through a political biography of Mujuru, the study reaches the conclusion that post-independence Zimbabwe offers limited space for women’s leadership, whether those women have liberation history credentials or not. The strategy of maternal dignity that Mujuru has used to navigate her political career is a “patriarchal bargain” with limited possibilities for women’s meaningful participation, and the transformation of political parties and governance in Zimbabwe. , Thesis (MA) -- Faculty of Humanities, Political and International Studies, 2022

- Description: The major economic copper sulphide deposits hosted in the late Mesoproterozoic intrusions of the Koperberg Suite in the O’okiep Copper District immediately overlie sulphur-bearing paragneisses of the Khurisberg Subgroup in an otherwise low-sulphur granitic basement. The dominant sulphide assemblage (chalcopyrite and bornite) hosted in the Koperberg Suite is also atypical of the intermediate solid solution (iss) assemblage (chalcopyrite and pyrrhotite) observed in most Cu-Ni magmatic sulphide deposits. This study presents sulphur isotope and in-situ trace element analysis of sulphides from the Koperberg Suite and the Khurisberg Subgroup with the view of placing constraints on the role of sulphide-bearing supracrustal metasedimentary of the Khurisberg Subgroup as a source of additional sulphur in the genesis of these deposits, and ore-forming (sulphide formation) processes which result in trace element variations registered by sulphides hosted in the Koperberg Suite. The high concentrations (up to 2100 ppm) of monosulphide solid solution (mss)-incompatible trace elements (e.g., Te, Se, Bi, Ag, Pb), and the depletion in Ni and Co (<40 ppm) of sulphides hosted in the Koperberg Suite are instead consistent with the derivation of such sulphides from a Cu-rich sulphide melt which segregated from a Ni-rich sulphide melt prior to magma emplacement in the middle crust, in agreement with one of the petrogenetic models for the Koperberg Suite proposed in the existing literature. The low S/Se ratios ( ̴650-10300) of sulphides hosted in the Koperberg Suite and the high S/Se ratios ( ̴18800-56000) registered by the main sulphide phase (pyrite) in the Khurisberg Subgroup argues against crustal contamination of the Koperberg Suite magmas by the Khurisberg Subgroup. The S/Se and Cu/S ratios of coexisting bornite and chalcopyrite hosted in the Koperberg Suite are positively correlated with the bornite modal abundance in the Koperberg Suite. Such trends are interpreted to be consistent with progressive oxidation of sulphide melt, a process which results in the crystallisation of iss-bornite assemblage and/or replacement of iss with bornite due to the enrichment of Cu and depletion in S of the sulphide melt. The oxidation of sulphide melt is likely to have been effectuated by the fractional crystallisation of mss in a prior sulphide melt segregation event and/or the fractional crystallisation of Fe2+-dominated silicate phases. Fractionation of the Cu-rich melt sulphide melt (segregated from mss) also tends to enrich the residual sulphide melts in Se. Thus, the chalcopyrite-dominated assemblage with S/Se ratios of ̴1300-10200 observed in the less basic rocks in the Koperberg Suite (leucodiorites and leuconorites) is interpreted to have formed from the least evolved sulphide melt, whereas the bornite-dominated assemblage with S/Se ratios of ̴650-5500 observed in the more mafic members of the Koperberg Suite (orthopyroxenites and norites) is interpreted to have formed from the most evolved sulphide melt. The ẟ34S isotopic signatures in sulphides of the Koperberg Suite (-1.4 to +1.91‰) and the proposed contaminant, the Khurisberg Subgroup (-1.2 to +3.5‰), overlap with the those of the Koperberg Suite below the Khurisberg Subgroup (+0.74‰) and typical mantle-derived magmatic rocks (0 ± iv 2‰). Hence, the sulphur isotope variations are inconclusive as an indicator of possible crustal sulphur assimilation into the intruding mantle magma. However, considering the trace element systematics and the sulphur isotope data, the Koperberg magmas likely attained sulphur saturation at deeper crustal levels. , Thesis (MSc) -- Faculty of Science, Geology, 2022

- Description: The empirical study investigates the relationship between inflation, credit markets and economic growth in the context of Brazil, Russia, India, China and South Africa (BRICS) countries. The BRICS group consists of five emerging market economies and was first coined by Jim O’Neil of Goldman Sachs in 2001 whereby initially the bloc consisted of only Brazil, Russia, India, China, South Africa joined the BRICS group in 2010. The BRICS bloc was deemed to be the top fast-growing economies that showed great potential for growth. Consequent to the 2008 global financial crisis, there has been a large change in economic thinking as policy-makers have struggled to overcome the economic misfortunes caused by the crisis. Amongst the emerging countries, the BRICS countries have in effect, established a New Development Bank to play the role of the credit facilitator the BRICS countries and other emerging countries as well. This BRICS New Development Bank was established in 2014 and already has identified and funded some projects within the BRICS countries. Moreover, the main objective of this bank is to provide credit to be utilised for infrastructure, climate change measures, as well as to ensure sustainable development. Against this backdrop, the current study investigates the role played by credit and the extent of development in credit markets on enhancing growth in the BRICS countries, particularly looking at the levels of inflation that are conducive to credit market development. The study notes that in order for credit expansion to be successful, the credit received by a country must reflect positively on a country’s economic growth. In other words, with more credit coming into a country, the expected result is that there will also be a rise in economic growth. Furthermore, seeing that inflation erodes the value of money, this credit or these funds that a country receives may not have the expected influence on growth. Therefore, the study finds it imperative to investigate the levels at which inflation allows for credit expansion to promote growth in a country. Furthermore, central banks play an important role in credit markets via the interest rate channel and the study examines the role of monetary policy in credit markets of each of the BRICS countries by looking at the inflation targeting regime as well as the absence thereof within these countries. Moreover, BRICS central banks share more or less the same goal of maintaining price stability and low inflation through various monetary policy tools. Therefore, achieving this objective will allow a central bank to gain both investor and consumer confidence which plays a role in a country’s investment rates. Moreover, inflation that is not controlled results in uncertainty which makes investors hesitant and unwilling to embark on investments. Ha, Ivanova, Ohnsorge and Unsal (2019) associate a developed financial sector with low inflation, stating that stable inflation rates eliminate uncertainty and avoids the erosion of the value of money. The current study used an Autoregressive Distributed Lag (ARDL) model to examine the linear co-integration and Non-linear Autoregressive Distributed Lag (NARDL) for the non-linear empirical analysis of the relationship between inflation, credit markets and economic growth in BRICS countries. The non-linearity of this relationship is important to study as there has been many debates on the nature of the inflation-growth relationships with some studies implying that it is positive, some say it is a negative relationship and some say it is non-linear. The annual data time series is extracted from the World Bank Indicators and the Penn State database covering the period 1960-2019. The main variables used in the study are Inflation (CPI), Credit (Domestic Credit to Private Sector) and Economic growth (GDP). The study conducted various regressions including the total of five linear regressions which were run individually for each country, the non-linear regressions consisted of three regressions for each country which were on 1) Only Inflation partitioned, (2) Only Credit partitioned and (3) both Inflation and Credit were partitioned. The partitioning of the variables is made possible by the NARDL model which allows variables to be partially decomposed into negative and positive sums to identify thresholds of variables which have various effects on other variables. The overall findings of the study suggest that although inflation exerts various effects on growth, according to this study’s results, it does not have a significant impact on credit for all the countries except for China whereby credit in general is conducive to economic growth and Brazil where growth is enhanced when credit is declining. The study revealed that generally, inflation exerts a negative impact on growth, therefore, authorities must focus on keeping inflation rates low particularly for Russia, India and South Africa as Brazil’s results suggest that rising inflation is conducive to its economic growth in the long run. According to the findings of this study, credit does not have the significant impact on growth even under different inflation thresholds. Furthermore, this does not imply that the credit channel is a futile tool for authorities, the relationship between inflation, credit and growth particularly with the hypothesis that inflation enhances credit market development and therefore growth, is not significant. , Thesis (MCom) -- Faculty of Business and Economic Sciences, School of Economics, Development & Tourism, 2021

- Description: The empirical study investigates the relationship between inflation, credit markets and economic growth in the context of Brazil, Russia, India, China and South Africa (BRICS) countries. The BRICS group consists of five emerging market economies and was first coined by Jim O’Neil of Goldman Sachs in 2001 whereby initially the bloc consisted of only Brazil, Russia, India, China, South Africa joined the BRICS group in 2010. The BRICS bloc was deemed to be the top fast-growing economies that showed great potential for growth. Consequent to the 2008 global financial crisis, there has been a large change in economic thinking as policy-makers have struggled to overcome the economic misfortunes caused by the crisis. Amongst the emerging countries, the BRICS countries have in effect, established a New Development Bank to play the role of the credit facilitator the BRICS countries and other emerging countries as well. This BRICS New Development Bank was established in 2014 and already has identified and funded some projects within the BRICS countries. Moreover, the main objective of this bank is to provide credit to be utilised for infrastructure, climate change measures, as well as to ensure sustainable development. Against this backdrop, the current study investigates the role played by credit and the extent of development in credit markets on enhancing growth in the BRICS countries, particularly looking at the levels of inflation that are conducive to credit market development. The study notes that in order for credit expansion to be successful, the credit received by a country must reflect positively on a country’s economic growth. In other words, with more credit coming into a country, the expected result is that there will also be a rise in economic growth. Furthermore, seeing that inflation erodes the value of money, this credit or these funds that a country receives may not have the expected influence on growth. Therefore, the study finds it imperative to investigate the levels at which inflation allows for credit expansion to promote growth in a country. Furthermore, central banks play an important role in credit markets via the interest rate channel and the study examines the role of monetary policy in credit markets of each of the BRICS countries by looking at the inflation targeting regime as well as the absence thereof within these countries. Moreover, BRICS central banks share more or less the same goal of maintaining price stability and low inflation through various monetary policy tools. Therefore, achieving this objective will allow a central bank to gain both investor and consumer confidence which plays a role in a country’s investment rates. Moreover, inflation that is not controlled results in uncertainty which makes investors hesitant and unwilling to embark on investments. Ha, Ivanova, Ohnsorge and Unsal (2019) associate a developed financial sector with low inflation, stating that stable inflation rates eliminate uncertainty and avoids the erosion of the value of money. The current study used an Autoregressive Distributed Lag (ARDL) model to examine the linear co-integration and Non-linear Autoregressive Distributed Lag (NARDL) for the non-linear empirical analysis of the relationship between inflation, credit markets and economic growth in BRICS countries. The non-linearity of this relationship is important to study as there has been many debates on the nature of the inflation-growth relationships with some studies implying that it is positive, some say it is a negative relationship and some say it is non-linear. The annual data time series is extracted from the World Bank Indicators and the Penn State database covering the period 1960-2019. The main variables used in the study are Inflation (CPI), Credit (Domestic Credit to Private Sector) and Economic growth (GDP). The study conducted various regressions including the total of five linear regressions which were run individually for each country, the non-linear regressions consisted of three regressions for each country which were on 1) Only Inflation partitioned, (2) Only Credit partitioned and (3) both Inflation and Credit were partitioned. The partitioning of the variables is made possible by the NARDL model which allows variables to be partially decomposed into negative and positive sums to identify thresholds of variables which have various effects on other variables. The overall findings of the study suggest that although inflation exerts various effects on growth, according to this study’s results, it does not have a significant impact on credit for all the countries except for China whereby credit in general is conducive to economic growth and Brazil where growth is enhanced when credit is declining. The study revealed that generally, inflation exerts a negative impact on growth, therefore, authorities must focus on keeping inflation rates low particularly for Russia, India and South Africa as Brazil’s results suggest that rising inflation is conducive to its economic growth in the long run. According to the findings of this study, credit does not have the significant impact on growth even under different inflation thresholds. Furthermore, this does not imply that the credit channel is a futile tool for authorities, the relationship between inflation, credit and growth particularly with the hypothesis that inflation enhances credit market development and therefore growth, is not significant. , Thesis (MCom) -- Faculty of Business and Economic Sciences, School of Economics, Development & Tourism, 2021

- Description: Customer Experience (CX) is the measurement of interaction between a customer and an organisation over a long time. Customer Experience is a strategic marketing effort that aims to improve the customer journey and touchpoints with the organisations’ product and services. It involves the complete customer journey – starting with the search process, purchase and after-sale processes of the experience. Google Trends identified that online users from all over the world search the key words “Customer Experience” more, often than not. This study considered a reliable measure for Customer Experience. This study endeavours to explore Customer Experience in the grocery retail sector in South Africa to put customer needs at the centre of their business. Extensive research on Customer Experience exist, however Customer Experience in the grocery retail sector in South Africa has not been measured using Professor Phillip Klaus’s new scale in CX. A broad literature review was conducted and Factors influencing Customer Experience in the grocery retail sector were identified and explored. The academic literature selected for the study is founded in the academic theories of Experienced Utility and Service-Dominant (S-D) Logic. The literature formed the foundation for the conceptual model that included the proposed Brand Experience (BE), Service Experience (SE) and Post-purchase / Consumption Experience (PE) independent factors. This treatise formed part of a bigger study of Customer Experience undertaken, using a questionnaire distributed via email, which 858 respondents completed. The study was quantitative. Data analysis included the use of descriptive and inferential statistics, Exploratory Factor Analysis, Reliability and Validity of Measurement, One-Sample T-Tests and the measurement of relationship between the factors. There is a need for companies to explore and understand CX in order to differentiate themselves strategically and to improve the bottom line. This study contributes to the body of knowledge by using academic literature and theories to explore Customer Experience in the grocery retail sector in South Africa. BE involves the customers’ perception of the brand and influence the customer’s experience. Customers look for clues to help inform their SE and expect companies to know their product and basic service promise. The findings of the study identified that BE and SE had a positive and significant influence on each other. Customers will show signs of commitment to an organisation during a positive PE. Similarly, the findings concluded that PE and CX had a statistical and practical significant positive correlation. PE was highlighted as a key determinant of CX. A positive CX will lead to a repeat purchases. Marketing managers need to take into account these factors when formulating CX strategies to influence the bottom line of the organisation. This study concludes with managerial recommendations that the grocery retail sector can implement to influence CX. Some of the recommendations include the appointment of a professional to manage all social media content; training and development opportunities for employees to enhance customer and shopping experience; and the use of customer data from loyalty programmes to promote personalised offers. In summary, a continuous review of CX with the emphasis on PE is recommended, to understand the changing needs of customers in the grocery retail sector. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business Administration, 2021

- Description: This paper proposes a franchise framework to ensure improved alignment between the franchisee and the franchisor in the South African retail tyre franchise industry. Countless studies have established that worldwide franchises offer more sustainable business development for entrepreneurs and a higher success rate for start-up businesses. This is, however, not an exclusive formula for success as the relationship between the franchisee and franchisor is dynamic with the economic landscape always changing. Entrepreneurs often display traits that do not always coincide with the franchisor’s framework. By developing a framework, the study aimed to supply possible solutions for improved alignment between the franchisee and the franchisor resulting in a prosperous relationship enabling economic growth and impacting positively on the unemployment crises in South Africa. A literature study was followed up with a case study research approach. The context was singular, namely a branded fitment centre franchise within the tyre fitment industry in South Africa. A schedule of interview protocols was undertaken with embedded multiple units of analyses based on feedback from franchise industry expert, franchisor representatives and franchisees who own various fitment centres. The case study research explored the factors that contributed to the successful alignment of the entrepreneurial paradigm to the franchise network requirements within a national franchise retail tyre fitment brand. Factors that ensure improved alignment between the franchisee and the franchisor requirements were explored in this research. Franchising provides comparable risks and benefits associated with other entrepreneurial ventures. However, entrepreneurs have a stronger chance of survival when aligning themselves with a franchise network. Franchising is critical for economic development. The study indicates that franchising influences the entrepreneurial paradigm. The entrepreneurial spirit needs to be curtailed to ensure compliance at times. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business Administration, 2021

- Description: This research project was developed from the idea that children's drawings reflect both their internal emotional lives and their external lived worlds. The subjects of the project were sexually abused children referred to Fort England Hospital during the first half of 1992. The Kinetic-Tree-House-Person projective drawing test was used as an instrument of assessment in conjunction with the Maudsley Child Psychiatric interview technique. Indications of the effects of sexual abuse were sought in drawing tests administered before and after interventions of ten sessions of group play therapy. Drawing tests were also administered to a control group of children. The research project explored the effectiveness of group play therapy interventions through comparison of pre intervention and post intervention drawings. The rationale for this project was the high incidence of rape and sexual abuse of prepubescent black young women in the Eastern Cape particularly, and in South Africa generally. There is need for both assessments of screening instruments and validation of therapeutic interventions if this problem is to be addressed adequately. , Thesis (MA) -- Faculty of Humanities, Psychology, 1993

- Description: The aim of this thesis is to explore and clarify what the experience of psychotherapy with ex-detainees entails. This investigation and analysis is conducted within the framework of a phenomenological method. The researcher elicits both the ex-detainees' and the therapist's experiences of psychotherapy. Initially the problematic nature of research in psychotherapy is layed out. This is followed by an overview of literature and theory on trauma and its conceptualizations from various psychotherapeutic perspectives. The treatment implications in each case are mentioned. Trauma occurs in the detention experience so detention is then briefly looked at in terms of torture basically and the detention syndrome, post traumatic stress disorder. Core personality processes in relation to this diagnosis are given and the stress recovery process is summarized. , Thesis (MA) -- Faculty of Humanities, Psychology, 1988
