- Description: Literacy in South Africa is in crisis. Inadequate learning and teaching materials, extensive curriculum changes, under-resourced schools and under-qualified teachers are all contributing factors to an alarming situation. Grade 1 African language reading schemes in South Africa are failing to provide young children with the necessary and appropriate practice required to facilitate home language literacy acquisition (NEEDU 2013). A detailed analysis of three isiXhosa Grade 1 graded reader series will show the short-comings of texts translated from English with no cognisance of isiXhosa phonic structures and little appreciation for the agglutinative nature of Nguni languages. Formulating a new, effective approach to the development of African language readers to facilitate reading literacy is urgent and of national importance. The innovative phonics-based methodology, as well as an appropriate instructional level used to develop the Vula Bula Grade 1 isiXhosa readers appears to be a viable blueprint for the development of early readers that can effectively help to ameliorate current deficient literacy levels in African languages. This research thus combines applied linguistics with literacy materials development.

- Description: A wide range of research locally points to intermediate phase learners having extremely weak basic number sense resulting in the dominance of inefficient strategies for calculations with the four operations, irrespective of the number range. The grade six Annual National Assessments (ANA) diagnostic reports for 2012 to 2014 also point to errors and misconceptions that tend to dominate learners’ computations in the four basic operations; such errors are often attributed to the use of either tallies or incorrectly applied mathematical procedures. Having the above context in mind and following informal conversations with teachers in the Uitenhage Education District, five teachers expressed an interest in running the afterschool mathematics clubs based on the South African Numeracy Chair (SANC) project model. The SANC project team ran workshops in April, May and June 2016 with nine teachers (five as facilitators and four others as co-facilitators in five different club sites) in which teachers were provided with key resources for use in their clubs. Fifteen club sessions ran in each club with grade six learners across the 2nd and 3rd terms. These clubs form the empirical field for this research, which aims to investigate the nature of learners’ evolving number sense, procedural fluency and teachers’ experiences of working with learners in the club space. The unit of analysis in this study is both the shifts evident in learners’ number sense and procedural fluency as a result of participating in the clubs and the teacher’s experiences of working with learners in those clubs as club facilitators. A social constructivist perspective of learning guides this study. Especially Vygotsky’s (1978) notion that cognitive development stems from social interactions and guided learning within the Zone of Proximal Development (ZPD) of children, guided by more knowledgeable others. Furthermore, Kilpatrick et al.’s (2001) strands of mathematical proficiency provide the conceptual frame with a particular focus on procedural fluency and number sense. A mixed method approach to data collection was used. Quantitative data has been drawn from learner’s scores on pre- and post- assessments on four basic operations. Visual progression spectra have been adopted from the Pushing for Progression (PfP) Programme which is an intervention Programme developed by the SANC project for club facilitators. They provide explanations of learner progression trajectories and how to analyse learner methods. Qualitative narratives were drawn from learner progression data, as well as teacher post club questionnaires and one-to-one teacher interviews. The findings of this research suggest that learner workings when used in conjunction with visual progression spectra can provide important clues to researchers and teachers. This in turn contributes to an understanding of where learners are in their mathematical learning and gives ideas for how to support learners to progress using more flexible methods of calculation, particularly for poor performing learners. Included, is the discussion of the effectiveness of the club space to enable such shifts and improve learner flexibility, fluency and performance as displayed in learner methods and scores of the pre- and post- assessments. The teachers’ observations about the relaxed atmosphere in the club space, small sized groups, learning through play with co-members may have enabled the shifts in procedural fluency and number sense in club learners. Additionally, implications of the study are discussed, and tentative recommendations are made for the DBE to consider.

- Description: Water is essential for food production, however South Africa’s water is already under pressure due to increasing population, food demand, and climate change, amongst other factors. Over the past years, there has been increasing demand for agricultural water use for food production due to these factors. Rainwater harvesting and conservation (RWH&C) for food production is one of the most promising approaches to address increasing demand of water. The Rhodes University Environmental Learning Research Centre have led a project with the Water Research Commission (Project No. K5/2277) focusing on the dissemination of RWH&C practice knowledge that involves some of the extension services in the Nkonkobe Municipality in the Eastern Cape, called the ‘Amanzi [Water] for Food’ project. While extension services were included in the project, the wider role of extension services in ‘disseminating’ RWH&C knowledge amongst farmers is not clear, a problem which provides the focus for this research, especially since there are changes in the designated role of extension services to become more responsive and reflexive in relation to farmers emerging needs, and in response to wider issues such as climate change and water scarcity. In general, there is agreement that the role of extension is to be active within the farming community, to facilitate social interactions and collaborative processes that often focus on activities that are intended to find, assess, interpret and adapt information, knowledge and evidence that are suitable for farmer’s needs. Extension should also be available to identify arising issues that the farmers experience that can be solved by the use of research knowledge. However, little is known with regard to whether extension officers are taking up this role effectively, especially in relation to RWH&C knowledge. Using document analysis, semi-structured interviews, field-based observations and focus group discussions, this research seeks to demonstrate the role of extension services in facilitating and supporting social learning of RWH&C practices amongst rural smallholder farmers for improved food security. It provides insight into the way in which extension officers are able to facilitate social learning using RWH&C knowledge, and the issues that affect the adoption of social learning approaches to extension support related to RWH&C knowledge uptake and dissemination.

- Description: Credit ratings play a well-established part in modern financial markets, reducing asymmetric information between investors and borrowers. In particular, sovereign credit ratings allow the world’s lesser-known economies to access a wider pool of international capital, while simultaneously allowing international investors to access a more diverse set of investment opportunities. The importance of sovereign credit ratings in terms of the cost of government debt in developing nations was observed. The relationship between sovereign credit ratings and average bond spreads over the time period spanning 2006 – 2017 was examined in 25 emerging economies. Regression analysis in the form of fixed-effects and random-effects models was used to determine the impact of changes in sovereign credit ratings on the cost of sovereign debt, controlling for certain macroeconomic factors. It was concluded that sovereign credit ratings are relevant in helping to determine the cost of sovereign debt for developing economies, but that they are not the only factor considered by global markets. The thesis therefore recommended further research into the factors affecting the cost of sovereign debt as well as further refinements to the methodologies that ratings agencies use to assign ratings.

- Description: Worldwide, there has been a growing realisation of the importance of Cultural and Creative Industries as a driving force for employment creation, income generation and economic growth. Therefore, there is a need in South Africa to study and understand these industries setting, and business environment. Shweshwe is a unique local fabric produced by Da Gama Textiles in the Eastern Cape province of South Africa. This fabric is used by many micro-enterprises as an input to make clothes and other items for traditional cultural celebrations and ceremonies. This study is about the micro-enterprises who use South Africa made textiles (i.e. shweshwe textile) as business input. More specifically, it looks at employment creation and income generation opportunities of the micro-enterprises that use shweshwe textile as an input. These micro-enterprises and shweshwe production are being threatened by the rising influx of cheaper ready-made imported clothes that mimic the shweshwe designs and colours, in some cases, the logo as well. This study also plans to estimate the size and discover the attributes of the micro-enterprises that use shweshwe as an input in their businesses in South Africa, in order to estimate the impact of the counterfeit shweshwe imports on those micro-enterprises. This study adopted a mixed-methods approach-using a combination of both qualitative and quantitative data collection methods. Face-to-face interviews with questionnaires, were done with a total sample of 62 owners of the micro-enterprises that use shweshwe as input, in the Western Cape (Cape Town) and Eastern Cape (i.e. Makhanda and East London), South Africa. Self-administered questionnaires were emailed to 20 Jackson’s Stores managers across the country. Lastly, face-to-face interviews were done with the key stakeholder-the representative of Cowie trading (the main shweshwe distributor) and Da Gama Textiles (the factory of shweshwe), during a field visit. The Qualitative data was analysed using thematic analysis, whereas the quantitative data was analysed using inferential and descriptive statistics. The results show, that the micro-enterprises that use shweshwe as input are a significant contributor in terms of employment creation and income generation in South Africa. They also reveal that there is a big number of micro-enterprises that use shweshwe as an input in SA. The findings showed an estimate of between 5077 and 6000 small businesses that are using shweshwe an input, which are associated with 10 900 to 12 900 jobs. It was also found out that there is a transformation in this industry, and that this sector is B-BEE compliant. There are also high levels of human capital in this industry. This is an important finding revealing that there is potential for future growth in this sector. Results also found that the majority micro-enterprise owners (80%) have no other source of income, meaning that they are highly reliant on their shweshwe sewing business income. Additionally, 85% of those business, shweshwe garments makes up half or more of their sewing business proceeds. This reveals that a decline in income caused by the import of ready-made clothes in “fake” shweshwe will have a negative impact on the micro-enterprises’ ability to contribute to economic growth and job creation in this industry. To show the impact of the import of ready-made clothes in “fake” shweshwe on the micro-enterprises’ ability to contribute to economic growth and job creation in this industry. In the questionnaires that were used to conduct face-to-face interviews with the micro-enterprises, respondents were asked to indicate whether they had other sources of income other than the income they generate from the shweshwe sewing business. They were further asked as follow up question to choose from a given list of possible options containing a range of percentages of their business income that comes from the work sewn with shweshwe. This question was asked in order to be able to see, if there were to be a decline in income caused by the import of ready-made clothes in “fake” shweshwe what impact it would have on the micro-enterprises that use shweshwe as an input. The theory of industrial organisation has adopted the view of that businesses operating in the formal sector are more efficient and productive than those in the informal sector (Lobato, 2010). The study found that the micro-enterprises that operate in the formal sector generate more turnover than the ones that operate in the informal sector. However, the theory was further tested by running OLS regression, the results showed that operating in the informal sector does not affect turnover when other variables are controlled for, however, that it does affect job creation. In closing, this thesis provides suggestions on how to support, and protect the micro-enterprises that use shweshwe as an input, in order to enhance this industry’s potential also to ensure its continuous contribution in terms of employment creation and income generation in South Africa.

- Description: In the context of South Africa, the supply of intermediate to high-level skills is central to economic growth and development. The post-school education and training sector is a critical source of these skills. Technical and Vocational Education and Training (TVET) colleges are expected to provide the intermediate to high-level skills that are required in a fast-changing global and national economy. In addition to fulfilling the goal of meeting the skills needs of the country, TVET colleges are expected to expand access to education and training opportunities and create pathways that will ensure smooth transitions for learners from college to employment. Using the third-generation labour market segmentation approach to the study of labour markets, this study sought to investigate the various socio-political factors that influence TVET college students’ perceptions about employment opportunities in the labour market with a NCV qualification. Using a qualitative methodology, this research investigated whether TVET students at Eastcape Midlands College felt adequately prepared for the labour market with their prospective post-secondary school qualification. The findings varied, with some students being of the view that the theoretical component of their programme of study could be improved to better prepare them for the labour market, and others, being of the view that the practical component could be improved. At a general level, the findings showed that the students did not have perfect knowledge of the availability of employment opportunities for their prospective qualifications.

- Description: This is a multiple case study of language practices in relation to the language-in-education policy of Botswana. The impetus for this study came after realising a decline in the academic achievement of learners as they move to higher levels of education. Taking into cognisance other factors like socio-economic background and marginalised communities, this study intended to investigate language practices at 3 primary schools at Standard 1, Standard 4 and Standard 7. Cases were selected from 3 various schools in different districts that present the language situation in Botswana. School A was in Kgalagadi district where the dominant spoken language is Shekgalagarhi, a minority language of Botswana. School B was in Southern district where the dominant spoken language is Setswana, the national language of Botswana and School C was in Gaborone city, the capital city of Botswana, where languages of Botswana come into contact and parents mainly use English to communicate with their children at home. Observation of language practices at these schools was the primary technique of data collection. The researcher also used questionnaires and focus group discussions for authentication. It was realised that whereas the language-in-education policy of Botswana is monoglossic, as it separates languages into separate functions, language practices in the three primary schools were transglossic, as they involved the use of different language varieties in the classroom.

- Description: This is a multiple case study of language practices in relation to the language-in-education policy of Botswana. The impetus for this study came after realising a decline in the academic achievement of learners as they move to higher levels of education. Taking into cognisance other factors like socio-economic background and marginalised communities, this study intended to investigate language practices at 3 primary schools at Standard 1, Standard 4 and Standard 7. Cases were selected from 3 various schools in different districts that present the language situation in Botswana. School A was in Kgalagadi district where the dominant spoken language is Shekgalagarhi, a minority language of Botswana. School B was in Southern district where the dominant spoken language is Setswana, the national language of Botswana and School C was in Gaborone city, the capital city of Botswana, where languages of Botswana come into contact and parents mainly use English to communicate with their children at home. Observation of language practices at these schools was the primary technique of data collection. The researcher also used questionnaires and focus group discussions for authentication. It was realised that whereas the language-in-education policy of Botswana is monoglossic, as it separates languages into separate functions, language practices in the three primary schools were transglossic, as they involved the use of different language varieties in the classroom. However, the researcher discovered that there was limited translanguaging that limited learner creativity and participation in class. The language practices revealed compliance and non-compliance of some schools to the national language-in-education policy. The researcher found language teaching to be one of the factors that limited content acquisition in content subject lessons. Realising the irrelevance of the policy to the linguistic needs of learners, this study proposes guidelines on the implementation of a multilingual micro policy that considers both the strong and the weak versions of translanguaging.

- Description: The applications of machine learning have created an opportunity to deal with complex problems currently encountered in radio astronomy data processing. Calibration is one of the most important data processing steps required to produce high dynamic range images. This process involves the determination of calibration parameters, both instrumental and astronomical, to correct the collected data. Typically, astronomers use a package such as Common Astronomy Software Applications (CASA) to compute the gain solutions based on regular observations of a known calibrator source. In this work we present applications of machine learning to first generation calibration (1GC), using the KAT-7 telescope environmental and pointing sensor data recorded during observations. Applying machine learning to 1GC, as opposed to calculating the gain solutions in CASA, has shown evidence of reducing computation, as well as accurately predict the 1GC gain solutions representing the behaviour of the antenna during an observation. These methods are computationally less expensive, however they have not fully learned to generalise in predicting accurate 1GC solutions by looking at environmental and pointing sensors. We call this multi-output regression model ZCal, which is based on random forest, decision trees, extremely randomized trees and K-nearest neighbor algorithms. The prediction error obtained during the testing of our model on testing data is ≈ 0.01 < rmse < 0.09 for gain amplitude per antenna, and 0.2 rad < rmse <0.5 rad for gain phase. This shows that the instrumental parameters used to train our model more strongly correlate with gain amplitude effects than phase.

- Description: Reality television or “factual entertainment” is a hybrid of old television formats and factual programming in order to create a “new” entertaining show designed to draw the attention of audiences and increase viewership ratings. South African Idol is one popular local example. Adapted from the British programme Pop Idol, the show promises upward mobility for the young star who wins the competition. This show has become a subject of conversation amongst young people in South Africa who aspire to the “success” and “celebrity” status that is produced by participating on the show. This paper uses a Cultural Studies framework in order to examine the relationship between texts and audiences as an aspect of the “circuit of culture,” with its interrelated moments of production, texts, consumption and lived experience. My research focuses on the text and audience “moments” of this circuit. Audience studies research suggests that we should situate television viewing and the meanings made of TV programs in the natural setting of the home, and that this setting should be taken seriously as a unit of analysis. This study therefore, seeks to understand the ways in which audiences make meaning of this television programme within the domestic context.

- Description: Communal rangelands provide habitat to many plants and animals. However, there is evidence that livestock cause range degradation. Range degradation occurs because livestock select grazing based on the availability of resources such as water and forage material, their use of the landscape is non-uniform, consequently causing resource deterioration. Range management is thus necessary because communities depend on range condition for livestock productivity. However, precise quantification of livestock distribution within communal rangelands is lacking. In developed countries, Global Positioning Systems (GPS) collars have been used to monitor wildlife and domestic livestock in pastures and seem to have worked efficiently. However, in a developing country like South Africa, GPS technology to monitor animal behaviour has been used only for wildlife on privately owned land. The high costs of monitoring livestock herds in large open areas such as communal rangelands have resulted in little or no monitoring of domestic livestock using GPS technology. This study links monitored livestock distribution to physical landscape variables in Mgwalana, and uses the modelled relationship to predict livestock distribution in quaternary catchments, T12A and T35A-E. The research addresses the questions (1) where do livestock spend time in the wet and dry seasons? And (2) how can areas of potential livestock distribution be identified in other catchments where actual distribution is unknown? Livestock were tracked during the wet and dry seasons using GPS collars. The resulting distribution data is combined with selected physical landscape variables to identify selectivity. The GPS location data and the physical landscape variables are used to predict potential livestock distribution where distribution is unknown in quaternary catchments (T12A and T35A-E). The ArcGIS Predictive Analysis Tool (PAT) was used to extract the selected landscape variable ranges based on the GPS location data and identify areas with the same conditions in the quaternary catchments were subsequently selected. The key findings are that livestock prefer accessible areas with gentle terrain near water sources, avoiding south-facing slopes which receive less solar radiation and tend to be cooler. Livestock are attracted to vegetation in riparian zones. Rural communal lands are dominated by poverty, and land-based livelihood strategies can potentially contribute to the well-being of the community. Therefore, understanding livestock distribution can contribute to a rangeland management strategy aimed at improving range condition which could increase livestock productivity and contribute to the livelihoods of local people.

Primary healthcare forms the basis of any healthcare service provision. Primary Healthcare for mental health is an essential component of any well-functioning health system. Making mental healthcare available in primary healthcare allows for early detection and early treatment while it is still easier and cheaper. Purposive sampling was used to recruit nursesand a government official in the Hhohho region in the Kingdom of Eswatini.The study found that there are major challenges in the primary health care clinics, and this negatively affects the WHO (2001) proposal on mental health integration into primary health care. This finding is similar to other low-income countries’ challenges in mental health integration into primary health care. The impact of neo-liberal policies on healthcare in Eswatini is explored and it is clear these policies impact the ability of the Ministry of Health to provide health care. The study also drew on the symbolic interaction perspective to understand the meanings that nurses attach to mental illness and their experiences mental health care.

Mesoscale alongshore and cross-shore transport and settlement of invertebrate larvae on the south east coast of South Africa

- Description: Pelagic larval stages of most marine benthic species are important in maintaining coastal populations of adults. Several physio-chemical factors such as currents, winds, larval behaviour and time have an influence on the dispersal and transport of larvae to the adult habitat but their role is however still poorly understood. The aim of this study was to investigate the alongshore and cross-shore transport and temporal delivery of invertebrate larvae at four sites (Kenton on Sea, Cannon Rocks, Schoenmakerskop and Cape St Francis) along the south east coast of Eastern Cape, South Africa. Larval distribution of several taxa was determined during two sampling periods, by collecting water samples at nearshore line transects (3 distances: 900m, 1500m and 2400m – perpendicular to the shore) and at three depths (surface, thermocline/middle, bottom), which ranged from 15m (inshore) to 50m (offshore). Physical properties (current speed and direction, dissolved oxygen, fluorescence, turbidity, temperature, salinity, pH, pressure, density and conductivity) were measured and coupled in order to further understand larval distribution. The larvae were analysed as both total abundance and separately as the abundances of a variety of taxa which were: Perna perna, Mytilus galloprovincialis, oysters, early and late nauplii and cyprids. Larval settlement and recruitment on the rocky shores were measured by monthly deployment and collection of 20 (10 each for barnacles and mussels) artificial collectors at each site, which were preserved in ethanol or frozen for further processing. Multiple Permutational Multivariate Analysis of Variance (PERMANOVA) analyses were used to test the effects of site, depth and distance from the shore for the nearshore larvae (taxa analysed separately). In addition, a distance based linear model (distLM) was performed to analyse the relationship between the total larval abundance and the above mentioned physical variables. Multiple two-way analyses of variance (ANOVA) were performed to test the effects of months and sites on the settlement and recruitment of the larvae (P. perna, M. galloprovincialis, other bivalves, cyprids and juvenile barnacles) arriving on the shore. For the nearshore larval distribution, results from the PERMANOVAs revealed that most taxa showed a significant site and depth interactions with the exception of ‘early nauplii’ taxon. Also nearly all taxa were found within the thermocline, besides ‘oyster’ and ‘cyprids’ which were located at thermocline or bottom. Larvae were also located at variable distances from the shore, with most occurring at the offshore stations. Furthermore, there was a geographical separation of larval abundance according to sites, with most larvae located at Cannon Rocks and Kenton on Sea and least at Schoenmakerskop and Cape St Francis. For the settlement and recruitment, most taxa showed a seasonal trend, with the highest abundance of settlers and recruits expectedly appearing during the summer months of the sampling period. Additionally there was a site effect for most taxa (P. perna, M. galloprovincialis, other bivalves and juvenile barnacles), where settlers and recruits were mostly found at Cannon Rocks. Significant differences in abundance of settlers and recruits amongst the four sites indicate spatial and temporal variability for the targeted 180km stretch of coast. Overall for this study, taxon and ontogenetic stage of larvae were important in the distribution and abundance of larvae. Throughout the time frame of nearshore and intertidal sampling, Cannon Rocks consistently resulted as a ‘hot spot’ for larval abundance, settlement and recruitment, while a broad west to east separation was also observed. These results hence highlight that within this stretch of c.180km coast, time, taxon, ontogeny and post-settlement factors influence early dynamics of benthic populations.

- Description: The Skorpion none-sulphide Zinc Deposit is located in the para-autochtonous Port Nolloth Zone of the Gariep Belt, which overlays the Lower-Proterozoic Orange River Group basement rocks (Corrans et al., 1993). Situated in close proximity to the larger Rosh Pinah Zn-Pb deposit, the Skorpion Deposit contained a resource of 24.6 Mt at 10.6 % Zn and unquantified Cu and Pb prior to mining. To date, zinc has been the only metal exploited, with minor amounts of copper as a by-product. This study aims at understanding the mineralogical composition of the Skorpion lead mineralization and understanding the relationship between lead and the major metals such as zinc and copper in order to form a basis for further work that could determine the potential of processing lead as a by-product. As part of the study, work was also done on lead isotopes mainly with the aim of understanding the mineralization genesis and to determine the differences between the Skorpion and Rosh Pinah deposit which rationalize the inferior economic potential of the Skorpion lead mineralization. Results of the study have shown that majority of the lead mineralization is hosted by the felsic metavolcanics as galena and subordinately in the metasiliciclastics as pyromorphite, a lead manganese phosphate. In terms of the mineral textures, the lead minerals appear to be mainly secondary phases that have been remobilized and reprecipitated around pyrite, within pyrite cracks and intergrown with minerals such as chalcocite and greenockite. Lead has been mainly concentrated along fault zones. The elevated pyromorphite concentrations tend to occur within gossanous zones in close association with iron and manganese oxides. These textures represent supergene enrichment of a sulphide proto ore. However, contrary to copper and zinc mineralization, lead was not remobilized far from the proto ore merely as a function of its poor mobility in acidic fluids (Reddy et al., 1995). This substantiates the concentration of secondary lead in the felsic metavolcanics and to a much lesser extent, in the metasiliciclastics. Both secondary zinc and copper were reprecipitated in the metasiliciclastics, further away from the sulphide proto ore, hosted mainly by the felsic metavolcanics. The average lead isotope ratios of 206Pb/204Pb (17.26), 207Pb/204Pb (15.60) and 208Pb/204Pb (37.42) resemble results provided by Frimmel (2004) for both the Skorpion and Rosh Pinah deposits. For the Skorpion samples from Frimmel (2004) had the following average ratios: 206Pb/204Pb (17.29), 207Pb/204Pb (15.59) and 208Pb/204Pb (37.51). The Rosh Pinah samples had the following average ratios: 206Pb/204Pb (17.17), 207Pb/204Pb (15.61) and 208Pb/204Pb (37.45). These results indicate lead derivation from the lower 2.0 Ga Eburnean pre-Gariep basement in agreement with and Frimmel et al. (2004). The host felsic metavolcanics might have been derived from melting of the basement rocks during the formation of the Adamastor Ocean. In comparison to the Rosh Pinah deposit lead isotope signatures, the Skorpion lead isotopes overlap with the Rosh Pinah deposit isotopes, but have a much narrower range. This is an indication of a much shorter lived and potentially faster mineralization event contrary to the SEDEX type Rosh Pinah deposit. The smaller tonnage of the Skorpion deposit, its inferior lead concentrations and the elevated radiogenic lead isotopes point toward a VMS deposit which was formed in a small graben fed by shallow conduits during a short lived mineralization event. Sedimentary rocks covered the forming deposit at a fast rate and impaired the deposit advancement. The interaction between the upper crustal rocks and the mineralizing fluids is what may have resulted in the elevated radiogenic lead signature. In contrast to this, SEDEX deposits such as the Rosh Pinah Deposit, are generally fed by deep seated conduits that allow more longer lived leaching of metals from the underlying basement rocks and generally allow minor influence from upper crustal rocks.

- Description: The Skorpion none-sulphide Zinc Deposit is located in the para-autochtonous Port Nolloth Zone of the Gariep Belt, which overlays the Lower-Proterozoic Orange River Group basement rocks (Corrans et al., 1993). Situated in close proximity to the larger Rosh Pinah Zn-Pb deposit, the Skorpion Deposit contained a resource of 24.6 Mt at 10.6 % Zn and unquantified Cu and Pb prior to mining. To date, zinc has been the only metal exploited, with minor amounts of copper as a by-product. This study aims at understanding the mineralogical composition of the Skorpion lead mineralization and understanding the relationship between lead and the major metals such as zinc and copper in order to form a basis for further work that could determine the potential of processing lead as a by-product. As part of the study, work was also done on lead isotopes mainly with the aim of understanding the mineralization genesis and to determine the differences between the Skorpion and Rosh Pinah deposit which rationalize the inferior economic potential of the Skorpion lead mineralization. Results of the study have shown that majority of the lead mineralization is hosted by the felsic metavolcanics as galena and subordinately in the metasiliciclastics as pyromorphite, a lead manganese phosphate. In terms of the mineral textures, the lead minerals appear to be mainly secondary phases that have been remobilized and reprecipitated around pyrite, within pyrite cracks and intergrown with minerals such as chalcocite and greenockite. Lead has been mainly concentrated along fault zones. The elevated pyromorphite concentrations tend to occur within gossanous zones in close association with iron and manganese oxides. These textures represent supergene enrichment of a sulphide proto ore. However, contrary to copper and zinc mineralization, lead was not remobilized far from the proto ore merely as a function of its poor mobility in acidic fluids (Reddy et al., 1995). This substantiates the concentration of secondary lead in the felsic metavolcanics and to a much lesser extent, in the metasiliciclastics. Both secondary zinc and copper were reprecipitated in the metasiliciclastics, further away from the sulphide proto ore, hosted mainly by the felsic metavolcanics. The average lead isotope ratios of 206Pb/204Pb (17.26), 207Pb/204Pb (15.60) and 208Pb/204Pb (37.42) resemble results provided by Frimmel (2004) for both the Skorpion and Rosh Pinah deposits. For the Skorpion samples from Frimmel (2004) had the following average ratios: 206Pb/204Pb (17.29), 207Pb/204Pb (15.59) and 208Pb/204Pb (37.51). The Rosh Pinah samples had the following average ratios: 206Pb/204Pb (17.17), 207Pb/204Pb (15.61) and 208Pb/204Pb (37.45). These results indicate lead derivation from the lower 2.0 Ga Eburnean pre-Gariep basement in agreement with and Frimmel et al. (2004). The host felsic metavolcanics might have been derived from melting of the basement rocks during the formation of the Adamastor Ocean. In comparison to the Rosh Pinah deposit lead isotope signatures, the Skorpion lead isotopes overlap with the Rosh Pinah deposit isotopes, but have a much narrower range. This is an indication of a much shorter lived and potentially faster mineralization event contrary to the SEDEX type Rosh Pinah deposit. The smaller tonnage of the Skorpion deposit, its inferior lead concentrations and the elevated radiogenic lead isotopes point toward a VMS deposit which was formed in a small graben fed by shallow conduits during a short lived mineralization event. Sedimentary rocks covered the forming deposit at a fast rate and impaired the deposit advancement. The interaction between the upper crustal rocks and the mineralizing fluids is what may have resulted in the elevated radiogenic lead signature. In contrast to this, SEDEX deposits such as the Rosh Pinah Deposit, are generally fed by deep seated conduits that allow more longer lived leaching of metals from the underlying basement rocks and generally allow minor influence from upper crustal rocks.

- Description: This research undertook an investigation in digital archaeology, modernisation, and revitalisation of the InetVis software application, developed at Rhodes University in 2007. InetVis allows users to visualise network traffic in an interactive 3D scatter plot. This software is based on the idea of the Spinning Cube of Potential Doom, introduced by Stephen Lau. The original InetVis research project aimed to extend this concept and implementation, specifically for use in analysing network telescope traffic. The InetVis source code was examined and ported to run on modern operating systems. The porting process involved updating the UI framework, Qt, from version 3 to 5, as well as adding support for 64-bit compilation. This research extended its usefulness with the implementation of new, high-value, features and improvements. The most notable new features include the addition of a general settings framework, improved screenshot generation, automated visualisation modes, new keyboard shortcuts, and support for building and running InetVis on macOS. Additional features and improvements were identified for future work. These consist of support for a plug-in architecture and an extended heads-up display. A user survey was then conducted, determining that respondents found InetVis to be easy to use and useful. The user survey also allowed the identification of new and proposed features that the respondents found to be most useful. At this point, no other tool offers the simplicity and user-friendliness of InetVis when it comes to the analysis of network packet captures, especially those from network telescopes.

- Description: The title of my exhibition Bittersoet alludes to the self-exploratory nature of my practice, as I interrogate the personal memories associated with objects that characterise the relationship between myself and my mother (mamma). This supporting document, Narratives and Home: Remembering an almost forgotten walk, considers the key conceptual concerns informing my practice. In this mini-thesis, I address the question: ‘What is a home?’. Drawing from my own Fine Art Practice, I explore how home can be examined as a product of the imagination, rather than only as a physical place. I consider how ‘home’ is constructed as the primary objective within an ideological framework defined by history, memory and narrative. Engaging beyond the idea of ‘home’ as a fixed structure or place, I examine the idea of ‘home’ as something fluid that is negotiated and defined by the interaction between objects and language. It is concerned with dialectics of memory and narrative as they pertain directly to an experience of both searching for and reimagining home through metaphorical representations. In particular, I explore how home can be seen as equally familiar and unfamiliar, existing in-between, always changing, never fixed, rather in a constant state of flux. The concept of home is addressed in a dialogical process by using Afrikaans as my mother tongue, I narrate informal conversations between myself and my mother. These conversations transform and expand into hybrid words, memories and narratives to form a layered continuous dialogue between my practice and research. This notion relates to exploring oneself and the ‘fictions’ of the past. The self being fundamental to the individual comprehension of both ‘place’ and ‘space’.

- Description: In recent years South Africa’s foreign and local denominated debt has been downgraded by the three major global credit agencies, Moody’s, Standard and Poor’s (S&P) and Fitch. The foreign debt has been downgraded to speculative grade or ‘junk’ status by all three agencies. Local debt has been downgraded to ‘junk’ by S& P and Fitch, but Moody’s currently maintains local debt at the lowest level of investment grade. Many economists believe that South Africa’s rapidly rising debt levels are the major contributor to the decisions to downgrade South Africa’s debt. Yet many countries with higher levels of debt continue to be rated investment grade. Clearly, factors other than the actual level of debt are important in determining the credit rating agencies’ rating decisions. The literature suggests several variables are important in determining a country’s sovereign credit rating. These variables include not just the ratio of government debt to gross domestic product, but also a country’s real growth rate, inflation, gross domestic product per capita, external balance to gross domestic product, default history and the level of economic development. In examining the proposition that it is not a country’s debt level per se that matters, but rather the dynamics surrounding that debt, this research also includes three additional variables that are not usually mentioned in the literature. These, based on van der Merwe (1993), are the real GDP growth rate less the real interest rate, the ratio of the fiscal balance to GDP, and the ratio of government interest payments to government expenditure. The purpose of this addition is to examine whether rather than a country’s debt level (debt to GDP variable), it is the sustainability of a country’s ability to service debt, as indicated by the three additional ‘debt dynamic’ variables, that is most important when determining sovereign credit ratings. Panel data analysis for a sample of 12 countries over the period 1996Q1 to 2017Q4 indicates that of the broad macroeconomic variables mentioned in the literature, government debt to GDP, the real growth rate, inflation (cpi), and default history are all statistically significant, with the coefficients having the correct signs in all specification of the model, with the exception of the real growth rate in Models 2 and 3. With regards to the debt dynamic variables, the real growth rate less the real interest rate, as well as the interest payments to government expenditure variables are found to be significant determinants of sovereign credit ratings. Thus, the findings of the research suggest that the level of debt alone is an inadequate determinant of sovereign credit ratings. The dynamics of debt along with other macroeconomic variables are also important determinants of a country’s credit rating. Concerning policy recommendations, it is evident that debt sustainability is important for sovereign credit ratings. Evidence of the direct importance of economic growth in determining credit ratings is mixed, but growth is a key driver of debt dynamics variables and therefore of ratings. This suggests that policy should focus on stimulating growth to reduce the gap between real growth and real interest rates as well as increasing the denominator of the debt to GDP ratio and increase the size of the tax base, which would improve government’s ability to service the interest payments on its debt.

- Description: This thesis has looked at the complex interplay between media consumption and identity formation amongst a group of black South African male students within the context of a racially homogenous communal viewing area located on the Rhodes University campus during the #FMF protests in 2016. Using qualitative research methods the study concluded that the group context of communal viewing helped the students structure and make sense of their daily lives. They actively divorced themselves from the main student populace in an attempt to escape lived experiences of a repressive institutional culture expressed through the university’s monolingual language policies, aesthetics and course material. These students embodied the characteristics of a diasporic community characterised by displacement, dispersal and the continuous re-articulation of differences across contradictory social, cultural and economic contexts. They grappled with an alienating environment by creating a safe space for cultural reproduction aided by the communal consumption of local television programmes. Preferences for local content broadcast in African languages were shaped by a linguistic marginalisation experienced on the Rhodes campus. The politicisation of the context through #FMF in turn politicised the students’ subjectivities leading to a need to be informed of the movement’s progression through evening news broadcasts. Discussions around campus life were dominated by #FMF and the collective experiences of marginalisation in and from the university space. Communal viewing of local television shows allowed this group of students to transcend decades of essentialised African ethnic divisions bringing forward a group identity premised on a lived hegemony signified by blackness.
