- Description: This work proposes and demonstrates a novel method for software development that applies formal verification techniques to the design and implementation of concurrent programs. This method is supported by a new software tool, CSPIDER, which translates machine-readable Communicating Sequential Processes (CSP) models into encapsulated, reusable components coded in the Go programming language. In relation to existing CSP implementation techniques, this work is only the second to implement a translator and it provides original support for some CSP language constructs and modelling approaches. The method is evaluated through three case studies: a concurrent sorting array, a trialdivision prime number generator, and a component node for the Ricart-Agrawala distributed mutual exclusion algorithm. Each of these case studies presents the formal verification of safety and functional requirements through CSP model-checking, and it is shown that CSPIDER is capable of generating reusable implementations from each model. The Ricart-Agrawala case study demonstrates the application of the method to the design of a protocol component. This method maintains full compatibility with the primary CSP verification tool. Applying the CSPIDER tool requires minimal commitment to an explicitly defined modelling style and a very small set of pre-translation annotations, but all of these measures can be instated prior to verification. The Go code that CSPIDER produces requires no intervention before it may be used as a component within a larger development. The translator provides a traceable, structured implementation of the CSP model, automatically deriving formal parameters and a channel-based client interface from its interpretation of the CSP model. Each case study demonstrates the use of the translated component within a simple test development.

‘That mountain cannot be beautiful for nothing’: Zakes Mda’s aesthetics of liberation

- Description: Zakes Mda is a prominent post-apartheid black South African novelist whose style has been described as experimental. He also wrote plays intended to ‘rally people to action’ during the apartheid years. The changes in the political and social situation in South Africa since 1994 have had significant implications for those writers and artists who produced protest literature and art. The changes in Mda’s own practice and approach to art are themselves quite telling. His experimental novels place him among those African artists pioneering a new chapter for black South African art and the self-reflexive nature of his novels suggest that he is aware of the fact and is consciously forming and reforming his ideas about what it means to be an artist in post-apartheid South Africa. This study will unpack the role of the artist and the function of art in the becoming new South Africa as represented in Zakes Mda’s novels, thereby hypothesizing Mda’s aesthetic philosophy, as may be deduced from his practice, for what an African artist and art should be. This will be done first by locating Mda in the debates around art and literature within the sociopolitical context of a South Africa in transition. Despite the fact that when it comes to public action in the post-apartheid situation, Mda distinguishes between his own role in society as an artist who is a social activist and the role intended for his work, his own novels reveal a desire for the artefact (or artwork) to have a developmental, educational or conscientizing function. This is evident in representations of the effects of art in what this study proposes to be his extended South African black Kunstlerroman, which spans three novels. It is also demonstrated in his ekphrastic novel, The Madonna of Excelsior, in which visual art is interpreted in the process of description, thereby educating the reader. Not only that, but the reader is made into an ‘almost viewer’ and taught how to ‘see’ art. What emerges in the process of this study is Mda’s aesthetic philosophy or what may be termed his ‘aesthetics of liberation’ concerning the role of the artist in post-apartheid South Africa, a suitable African audience and how art works theoretically, as expressed through his fiction.

- Description: Documenting areas with natural groundwater reservior connectivity using isotopes before the anticipated shale gas development in the Karoo Basin of South Africa could contribute to developing legislative framework for hydraulic fracturing. In this study, groundwater dynamics (primarily connectivity between old/deep and low temperature modern/shallow (<25°C) groundwater) are studied using isotopes (14C, δ18O-δ2H, 3H, and δ13C) in conjunction with geochemical parameters (sampling depth (masl) and (mbgl), temperature (°C), Electrical Conductivity (EC) (μS/m) and sustainable yield (l/s)). Previous groundwater studies conducted in the Karoo Basin suggest that 14C (pMC) has the least overlap among isotope signature constraints between the different aquifer/groundwater groups. The outcomes of 14C analysis for this study suggest that one groundwater sample is an old/deep groundwater sample (<53 pMC), and that three groundwater samples are composed of shallow/young groundwater mixed with old/deep groundwater (<74 pMC). These four relatively older samples have calculated 14C ages ≥ 1700 years and were collected from boreholes that are north-east of the Cape Mountains (~50 km). The position of these samples suggests that deep-seated faults within the Cape Mountains and the basement of the southern Karoo Basin act as preferential pathways for deep groundwater migration (as is consistent with existing deep geophysical data) to shallower depths (<60 mbgl) where it cools and/or mixes with low temperature groundwater (<25°C). Three more groundwater samples were found to match the relatively old calculated 14C ages (≥ 1700 years) of the groundwater samples collected close to the Cape Mountains even though they have modern 14C (pMC) concentrations (>74 pMC). This implies that adjusting the 14C content in Dissolved Inorganic Carbon (DIC) based on its dilution by 14C free carbonates is influential in controlling the mixed groundwater ages, and that relatively older groundwater occurs at shallow depths in other parts of the study area possibly due to linked fault systems between deep and shallow aquifers. δ18O-δ2H relationships for the sampled groundwater suggest that groundwater samples collected within the main drainage of the Great Fish River plot close to the Global Meteoric Water Line (GMWL) indicating that the recharge water to this groundwater does not experience significant evaporation. The average isotope composition of the recharging water for the all of the sampled groundwater is -7.90 ‰ and -46.72 ‰ for δ18O and δ2H, respectively. This result plots halfway between rainwater 18O-2H relationship lines for the Indian Ocean and the Atlantic Ocean. This suggests that the rainwater from which the sampled groundwater was derived from evolved from both the Indian and Atlantic Ocean waters.

- Description: South Africa occupies a unique space in terms of the decolonization of the continent of Africa. While massive projects of decolonization where happening across the continent, South Africa was subjected to a conservative and racialised project of segregation. This arrested development makes for an interesting anachronism in South Africa as disconcerting “Third- World” and “First-World” economies emerged creating an anomalous temporality. I was born just a month before the inimitable Ruth First was unceremoniously assassinated in Mozambique in 1982. While further South, one of the most underreported conflicts of apartheid South Africa was in its nascent stages no further than a kilometer away from my house. I am referring of course to the violent clashes between factions of both the Inkatha Freedom Party (IFP) and the African National Congress (ANC), played in the men’s hostel of the third largest township in the country, Umlazi, South of Durban. These would only come to have meaning to me later, when I was at university. I mention these cultural and perhaps socio-political artefacts in so far as they relate to the kind of environment that lead to this research enquiry. Which is to say that as social beings, we are in fact products of the things that affect the social environment that we exist in. This is not a new idea. What is particularly interesting for this enquiry is the eclecticism of the emblems that survive to shapes one’s own identity and perception of the world around them. Within the above stated mini-biography lies a complex matrix of emotions and extrapolated meanings mediated through a conflicted and negotiated understanding of what the social history of South Africa meant for my own personal history. This paper is an attempt to think through articulations of time as they are constituted by future-orientated subjectivities extending back to varied pasts. It does so by exploring a recent work of black South African self-writing, Jacob Dlamini’s Native Nostalgia (2009). Considering the text’s treatment of time, I argue that porous conceptions of temporality open up possibilities for self-enunciation. What Paul Gilroy has described as “the signs of sameness” (2000, 101). Meaning that these could be quantified and as such researchable and in fact applied across various cultural texts (including but not limited to film). The body of work from South African documentary filmmaker Rehad Desai provides an interesting case study to examine Jacob Dlamini’s thematic pre-occupations with nostalgia. Nostalgia here is used to see if such pre-occupations can be applied to a filmic body of work. Desai’s body of work is interesting to this enquiry because it almost exclusively deals with the temporalities of South Africa as “refracted through the prism of the past”. By this I mean Desai through his work appears to reflect on South Africa’s storied past as it affects current happenings. It is the intention of this paper to argue that Desai deals with his subject (the evolution of the South African political landscape) in similar terms to the way Jacob Dlamini explores the notion of reflective nostalgia.

- Description: This is a qualitative study exploring the integration of mental health into primary healthcare in the Kingdom of Eswatini. 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.

- Description: The aim of this study is to assess control systems in asset management at the Middledrift Department of Correctional Services. It seeks to establish how control systems are used as asset management tools for financial reporting and for compliance with financial management prescripts as prescribed by the Auditor-General. The specific objectives of the study are to assess the nature of control systems used in asset management at the Middledrift Department of Correctional Services; to establish the extent to which financial reporting control systems comply with financial management regulations prescribed by the Auditor-General; and to establish the mechanisms, processes, and procedures that are in place at the Middledrift Department of Correctional Services for compliance with financial management regulations in asset management This study is motivated by the repetition of qualified audit reports on asset management the Middledrift Department of Correctional services keeps on receiving over the years. The study is therefore, significant in that it seeks to address how the Middledrift Department of Correctional Services can best address issues of complying fully with financial management regulations in asset management, so as to ensure that issues highlighted in the Auditor-General’s report do not recur. This study adopted a qualitative research methodology. Data was collected by means of interviews, focus-group discussions, observations and official documents. In-depth interviews were conducted with the head of the correctional centre, head of supply chain management and four employees within the supply chain management section. Focus group interviews were conducted in three groups. The first and second group consisted of 5 asset controllers each and the third group consisted of 5 sub-asset controllers. The researcher observed how assets are verified in the Middledrift Department of Correctional Services, and observed the process of asset reconciliation between Basic Accounting System and Logistical Information System. The sample for this study consisted of 21 respondents (n=21)comprising of the following respondents: the head of correctional centre, head of supply chain management, four employees within the supply chain management section, 10 asset controllers and five sub-asset controllers. The respondents were selected using purposive/judgemental sampling. Data obtained through transcribed in-depth interviews, focus group discussions was transcribed verbatim.

- Description: The aim of this study is to assess control systems in asset management at the Middledrift Department of Correctional Services. It seeks to establish how control systems are used as asset management tools for financial reporting and for compliance with financial management prescripts as prescribed by the Auditor-General. The specific objectives of the study are to assess the nature of control systems used in asset management at the Middledrift Department of Correctional Services; to establish the extent to which financial reporting control systems comply with financial management regulations prescribed by the Auditor-General; and to establish the mechanisms, processes, and procedures that are in place at the Middledrift Department of Correctional Services for compliance with financial management regulations in asset management This study is motivated by the repetition of qualified audit reports on asset management the Middledrift Department of Correctional services keeps on receiving over the years. The study is therefore, significant in that it seeks to address how the Middledrift Department of Correctional Services can best address issues of complying fully with financial management regulations in asset management, so as to ensure that issues highlighted in the Auditor-General’s report do not recur. This study adopted a qualitative research methodology. Data was collected by means of interviews, focus-group discussions, observations and official documents. In-depth interviews were conducted with the head of the correctional centre, head of supply chain management and four employees within the supply chain management section. Focus group interviews were conducted in three groups. The first and second group consisted of 5 asset controllers each and the third group consisted of 5 sub-asset controllers. The researcher observed how assets are verified in the Middledrift Department of Correctional Services, and observed the process of asset reconciliation between Basic Accounting System and Logistical Information System. The sample for this study consisted of 21 respondents (n=21)comprising of the following respondents: the head of correctional centre, head of supply chain management, four employees within the supply chain management section, 10 asset controllers and five sub-asset controllers. The respondents were selected using purposive/judgemental sampling. Data obtained through transcribed in-depth interviews, focus group discussions was transcribed verbatim. The transcribed data as well as data from observations were analysed using opencoding. Emerging codes and patterns were clustered into themes the data was compared within the categories to establish connections in the meanings as well as variations. The results of the ii study suggests that control systems used in asset management at the Middledrift Department of Correctional Services are far from satisfactory.

- Description: Generation of electricity from solar energy by photovoltaic systems has the potential to reduce dependence on non-renewable sources for electrical energy production. It can also reduce the cost of electricity for consumers by moving away from the traditional models of centralised generation combined with extensive transmission. The prices of photovoltaic system components have decreased so dramatically in recent years that nowadays a large portion of the cost of electricity produced by photovoltaic systems is due to the cost of investment capital rather than the cost of the physical parts of the system. The cost of capital is determined by the perceived risk of the investment and is contingent on predictive models whose aim is to project outputs reasonably achievable by the system. The output of a photovoltaic system depends strongly on external factors, like solar radiation and temperature, as well as internal, system specific factors. Models that can accurately predict the output of a photovoltaic system have direct impact on investment cost. Several measures, like root-mean-square-error or coincident of determination, have been used in the past to assess accuracy of models but they appear to be inadequate for the task. I suggest a new method, comprising qualitative and quantitative measures, for model evaluation and introduce two new quantities to assess the predictive capabilities of the models. Models of several photovoltaic systems in Namibia were created, the new evaluation approach was applied to them and the results were compared to the conclusions that would have been drawn if the old measures were used. Outdoor current-voltage measurements are used to assess the power output and general state of the solar generator of a photovoltaic system, but the measured values strongly depend on irradiance and temperature. The prevailing approach has been to transform the current-voltage characteristics to standard-test-conditions with the so-called translation equations and then compare the translated power to the nominal value. The translated value of the power, however, depends on the translation equations used and is not necessarily an accurate reaction of the state of the solar generator. I have proposed a new method for assessment of the state of the solar generator that relies only on the measured quantities and does not require translations to standard-test-conditions. This alternative method has been used in the assessment of the condition of the solar generators in the systems included in this study.

Evaluation of pre-treatment methods on production of bioethanol from bagasse and sugarcane trash

- Description: A variety of methods have been researched on for bioethanol preparation from different feedstocks. Amongst the available feedstock, one such feedstock is the sugarcane plant. In most of the research on bioethanol preparation with sugarcane the sugary juice has been widely used, with the bagasse and trash having been discarded as waste. The “waste” bagasse and trash are usually removed and thrown away or burnt during harvesting or in sugar mills to supplement energy requirements. This research on lignocellulosic bagasse and trash was done so as not to discard them but to rather find ways in which to use this biomass constructively. Alternatives to burning that can potentially add value to this biomass need to be researched on by evaluating their hydrolysis content. The different lignocellulose pretreatment methods of concentrated and dilute acid pretreatment, with subsequent enzyme hydrolysis as well as alkali and oxidative alkali pretreatment with enzyme hydrolysis were experimented on the bagasse and trash for hydrolysis efficiency and effectiveness. There are two types of acid hydrolysis which were investigated on which are concentrated and dilute sulphuric acid pretreatments. Use of concentrated sulphuric acid yielded the highest amounts of reducing sugars but also resulted in the highest amounts of downstream process inhibitors formation. This resulted in the need for neutralisation steps which in turn increase the overall costs of using this method to obtain reducing sugars. It has however the advantage of occurring at a faster rate, within minutes or hours, than using biological enzymes which took days, up to 72 hours to obtain the highest reducing sugar amounts. Dilute sulphuric acid pretreatment offered the advantage of using fewer chemicals which are therefore less severe on equipment and result in fewer fermentation inhibitors being formed. Dilute sulphuric acid hydrolysis also takes a relatively shorter period than biological methods of pretreatment. A challenge of fermentation inhibitors formed during acid hydrolysis was countered by using the methods of overliming (calcium hydroxide) and comparing it to neutralization with sodium hydroxide. Alkali pretreatment with sodium hydroxide was researched on by applying different pretreatment concentrations during experiments on the lignocellulosic biomass. There was an increase in the available quantities of cellulose with a significant reduction in lignin with pretreatment. Alkali pretreatment proved effective in exposing the cellulose which made v more cellulose surface area available to cellulase enzymes for enzyme hydrolysis. The highest yield of reducing sugars was obtained from hydrolysates pretreated with 0.25 M sodium hydroxide for 60 min and a period of 72 h of enzyme hydrolysis. In general the longer the pretreatment time the more reducing sugars were produced from the enzyme hydrolysis. Alkali peroxide pretreatment also resulted in significant reductions in lignin quantities of lignocellulose material. In this method sodium hydroxide in combination with hydrogen peroxide were used in pretreating the biomass. Hydrolysates with even fewer fermentation inhibitors were produced as a result. The highest percentage concentration of cellulose of 63% (g/g) was achieved after pretreatment of bagasse with 5% alkali hydrogen peroxide and trash with 0,25M sodium hydroxide pretreatment. Pretreatment of biomass using alkali with subsequent enzymatic hydrolysis gave the highest yields of fermentable sugars of 38% (g/g) using 7% (v/v) alkali peroxide pre-treated trash than 36% (g/g) for 5% (v/v) with the least inhibitors. Reducing sugar yields of 25% (g/g) and 22% (g/g) were obtained after pretreatment with concentrated and dilute acid respectively. Neutralization of the acid hydrolysates was necessary to reduce inhibitors formed with neutralisation by sodium hydroxide resulting in low dilutions and loss of fermentable sugars as unlike in the case of overliming. Subsequent steps of fermenting the reducing sugars resulting from pretreatment into bioethanol were based on using the yeast Saccharomyces cerevisae. Pretreatment hydrolysates from alkali peroxide experiments produced higher bioethanol yields of 13.7 (g/l) after enzyme hydrolysates versus 6.9 (g/l) bioethanol from dilute acid hydrolyzates. A comparison of the effects of time showed there was more bioethanol yield of 13.7 (g/l) after 72 h of fermentation with the yeast versus 7.0 (g/l) bioethanol after pretreatment for 24 h. The only drawback is the longer fermentation period which thus reduces the process and so reduces the value of the increase in yield

- Description: In South Africa, most of our children learn in a language other than their home language. Language and Literacy is thus a major concern for many of them who are trying to make meaning of literature. This study was part of a continuing community dialogic engagement project, between the university and a rural high school in Paterson, a rural settlement in the Eastern Cape. The selected school – ‘Sandhill High’ has English as the Language of Teaching and Learning (LOLT) but has predominantly isiXhosa- and a smaller number of Afrikaans home language learners. The aim of this research was to explore how English second language learners, in a rural high school engage with and experience a dialogic approach to writing as a social practice. This was firstly done by, investigating in which ways dialogic writing might encourage participation in literacy as a social practice. Secondly, exploring in which ways the choices of language might engage learners in responding to text. A qualitative, participatory case study was used to interpret the phenomena. To adequately address the research questions, this study was underpinned by Bakhtin’s theory on Dialogism, viewed through the lens of a third space. As this study was about writing, theories of literacies and second language writing were also reviewed. Dialogic journals offer reflective spaces for learners to record their thinking and because reading and writing complement each other, both need ongoing practice. The data was gathered using the dialogic journals and focus group discussions. Data was analysed in a process of thematic narrative analysis. Participation was voluntary and 16, grade 10 learners of the school participated in the study. The significance of this study was that it enabled learners to engage with texts using their choice of language to participate in dialogic journal writing as a social practice.

- Description: HIV is a disease that has a myriad of effects across different settings, and its prevalence varies across countries with different epidemiological drivers. The growing and disproportionate impact on young women has encouraged new ideas in HIV prevention strategies. The profusion of studies on HIV prevention strategies notwithstanding, the aspect of condom innovation has been largely ignored in literature. Drawing on the Diffusion of Innovation theory, this study examines how Max condoms have gained popularity among young women aged 18-24 years. The hypotheses are tested using an innovation-decision conceptual model and a comprehensive data set of 131 participants from rural, peri-urban and urban districts in KwaZulu Natal. Results reveal that the impact of marketing material and an effective public launch were significant in increasing Max condoms uptake, while the influence of peers and other members of one’s social system are critical for normalising the behaviour change. Young women have adopted Max condoms and uptake is continually influenced by positive perception of Max condoms’ relative advantage.

- Description: This study sets out to analyse the co-emergence of visualisation and reasoning processes when selected learners engaged in solving word problems. The study argues that visualisation processes and mathematical reasoning processes are closely interlinked in the process of engaging in any mathematical activity. This qualitative research project adopted a case study methodology embedded within a broader interpretative orientation. The research participants were a cohort of 17 mixedgender and mixed-ability Grade 11 learners from a private school in southern Namibia. Data was collected in three phases and comprised of one-on-one task-based interviews in the first phase, focus group task-based interviews in the second, and semi-structured reflective interviews in the third. The analytical framework was informed by elements of enactivism and consisted of a hybrid of observable visualisation and mathematical reasoning indicators. The study was framed by an enactivist perspective that served as a linking mediator to bring visualisation and reasoning processes together, and as a lens through which the coemergence of these processes was observed and analysed. The key enactivist concepts of structural coupling and co-emergence were the two mediating ideas that enabled me to discuss the links between visualisation and reasoning that emerged whilst my participants solved the set word problems. The study argues that the visualisation processes enacted by the participants when solving these problems are inseparable from the reasoning processes that the participants brought to bear; that is, they co-emerged.

- Description: The Performance management and development system has been introduced in the South African Public Service with the intention of monitoring, reviewing, assessing performance, developing under performers, recognising and rewarding good performance of the public officials. It is also there to develop the public officials who fail to attain required expectations. This study focuses on investigating whether employees do understand Performance Management and development system for the effectiveness of employee performance in the Eastern Cape Office of the Premier and that this has with the motivation of the public sector in the Eastern Cape, and the correlation that this has with the motivation of the public officials to improve performance. A qualitative research design was used for this study to investigate whether employees do understand effectiveness of PMDS on employees performance. The research design consisted of a case study where seven interview questions were conducted with the first employees from level four to level eight (operational staff), middle managers from level nine to level twelve and senior managers in the Office of the Premier Eastern Cape. Data analysis led to thematic analysis two themes were developed from the objectives of the study. This study has made the following recommendations: The employees in the Office of the Premier should be regularly monitored and evaluated on how to implement performance management and developed system. As a result, the study will give more understanding in aligning with the OTP strategy and drive individual performance, but will also assist all levels of employees within the OTP: EC in understanding the day to day operational activities of performance management. It will also help employee support and talent management professionals in knowing and understanding the best practices to adopt, in managing their individual performance levels.

- Description: The purpose of this research is to explore access and control of biodiversity in the context of biopiracy with specific reference to the case of pelargonium sidoides in the Raymond Mhlaba Local Municipality. The research is informed by the increased appropriation of local biodiversity and indigenous knowledge by industry as well as global debates on promoting sustainable resource utilisation and sustainable rural livelihoods. This study adopts a two-pronged conceptual approach mainly, Marx’s Ecology and the Sustainable Rural Livelihoods Framework (SRLF). The former provides useful insights into the processes and dynamics of power asymmetries between developed and developing countries, capital accumulation, inherent displacement and the predatory nature of capitalism. Whilst the latter addresses how livelihoods are fashioned in a holistic way. As a significant starting point the South African political economy is examined through the lens of the two economies debate. This research is primarily qualitative using in-depth interviews, observations and archival research as the primary data collection techniques. Preliminary site visits were conducted to negotiate access. Key informants of the study were representatives of the core groups (interested and affected stakeholders) involved in the case of pelargonium sidoides. Specifically, participants included representatives from the Imingcangathelo Community Development Trust and the Masakhane Community Property Association, local harvesters, local community members, monitoring and enforcement environmental officers, plant breeders (cultivators), scientists, local businessmen involved in natural resource trade, academics, legal representatives and non-governmental organisations. The Rhodes University research ethical guidelines were followed accordingly. The findings of the study suggest that trade in pelargonium sidoides is influenced by a complex and dynamic interplay between the state-industry-rural elite coalitions. Moreover, that this activity is largely centralised and exclusionary. This process is depicted in the unsustainable utilisation of pelargonium sidoides and other natural resources, the dismantling of local livelihoods, exploitation of harvesters and an incoherent environmental governance structure. At the core of this unequal system of exchange is industry, which effectively functions to generate profits whilst dispossessing peripheral communities such as the Masakhane community. The study therefore, argues that in order for local communities to access the trade there needs to be a shift in this system of unequal exchange. Not only regarding beneficiation, but in building community capacity and becoming involved as critical stakeholders in the governance of resources in the study area. The study found that there are competing narratives that inform the status and sustainability of pelargonium sidoides. Furthermore, given the current trajectory of the Masakhane community’s struggle for land, access to natural resources and exclusion from decision-making regarding pelargonium sidoides, the area will continue to be underdeveloped with concomitant poverty, inequality and comprised rural livelihoods.

- Description: Previous studies conducted on wool production in the communal areas of the Eastern Cape have concluded future research should focus on whether the observed differences in average wool price received between shearing sheds are due to differences in clip preparation (i.e. classing) or differences in the quality of the wool being produced (i.e. genetics).The objective of this study was to establish whether there are indeed geographical differences in the average wool price received by communal wool producers in the Eastern Cape and, if so, whether this difference in earnings is attributable to differences in the quality of wool produced and/or clip preparation. The current research explored eight years of wool production records of communal wool farmers (2009/10 to 2016/17) obtained from BKB, the largest wool broker in South Africa. Statistical analyses included descriptive statistics, analysis of variance, parametric tests (i.e. t-test) and multiple regression analysis. The conclusions drawn from this study are: that there are indeed statistically significant differences in the average wool price received between the different geographic areas of the Eastern Cape communal regions, and that the primary determining factor is wool quality, while clip preparation also plays an important but secondary role. The study identified specific geographic areas where developmental interventions are most critical, with specific emphasis on improving the genetic composition of the wool sheep flocks. Specific strategies are recommended, namely:Removing inferior-quality rams and replacing them with superior-quality rams to prevent any inferior nondescript rams from breeding and producing progeny; Replacing the inferior-quality nondescript ewes in specific areas with superior-quality ewes, and Improving the survival rate of lambs and thereby contributing towards expediting the rate of genetic improvement of the communal wool sheep flocks.

- Description: It is increasingly recognized that the cultural and creative industries (CCIs) can play an important role in economic growth and development. Governments around the world, including South Africa, are implementing culture‐led economic growth and development strategies on national and regional scales. CCIs tend to cluster around large cities because of existing hard and soft infrastructure such as networking advantages and access to skilled labour, however, much less is known about the potential of the CCIs to drive rural development. This thesis thus investigates the potential of the CCIs to cluster in small towns and rural areas. Moreover, it examines the relationship between the CCIs and socio‐economic development. The CCIs have been touted as a catalyst for economic growth and development and so have often been used in urban regeneration schemes. The Sarah Baartman District (SBD) of South Africa’s Eastern Cape has identified culture as a potential new economic driver. Establishing a new development path is necessary as the former economic mainstay, agriculture, has declined in the region, creating poverty and unemployment problems. However, the SBD has only small towns which, according to the literature, are not suited to CCI clustering. Despite this, there is evidence of cultural clustering in some of the SBD’s small towns like Nieu Bethesda and Bathurst. This research therefore conducted an audit of the CCIs in the district and used geographic information systems (GIS) to map their locations by UNESCO Framework of Cultural Statistics (FCS) domains in order to determine the extent to which clustering has occurred in a small town setting. The audit identified 1 048 CCIs operating in the district and determined that clustering is possible within some small towns, depending on their demographic, economic, social, geographic and historic characteristics. For small towns where clusters exist or the potential for cluster formation is present, the domains in which the town holds a comparative advantage, based on domain proportions and location quotients, should be pursued for local economic development (LED). In this case, Visual Arts and Crafts and Cultural Heritage were prominent throughout the district while Design and Creative Services and Performance and Celebration had small regional concentrations. Theory suggests that the presence of CCIs is linked to higher levels of economic development as the creative class is more likely to be attracted to more highly developed areas, usually large cities. Furthermore, spillover effects from cultural activity promotes further development under the virtuous cycle. To investigate the relationship between CCI clusters and socio‐economic development, the locational data of municipal level CCI numbers is overlaid with a regional development indicator, a socio‐economic status index, which is based on census data and includes economic and social components. Results show that there is a general positive trend of CCIs locating in larger numbers (clustering) in areas with higher socio‐economic development performances.

- Description: The need for detailed spatial soil information is increasing in the fields of environmental studies, agriculture as well as engineering practices. Regarding soil erosion in South Africa, border lines between sensitive soil forms in the Duplex soil group and resistant soil forms in the Oxidic soil group need to be mapped to a high accuracy to prevent/manage erosion and major soil losses. In third world countries like South Africa, digital soil mapping (DSM) with the use of machine learning can provide the solutions to fill numerous gaps in these related fields. Local DSM research has been ongoing at the University of the Free State and related institutions for the past eleven years. It has also been used commercially and can therefore be regarded as fruitful. The National Resource Management unit of the Department of Environmental Affairs required a soil map regarding the susceptibility of the soil to erosion for catchment T35 D-E (87 000 hectares) in the Mzimvubu management area of the Eastern Cape, South Africa. Through a DSM approach, machine learning was used to predict the occurrence of soil forms and soil families in accordance with the South African Soil Classification System. A total of 591 soil observations were made at specific points, pre-determined with the conditioned Latin Hypercube sampling (cLHS) method. These pre-determined points were classified into nineteen soil forms and forty eight soil families. The soils were then further divided into nine soil groups, based on their inherent sensitivity to erosion. Outlier observations were omitted from the dataset to create a reliable framework to predict the soil groups as influenced by the SCORPAN factors. These soil groups were mapped and evaluated with an accuracy of 68% and a Kappa statistic value of 0.42 that compare well with other soil maps, both locally and internationally. Mapping soil with an acceptable accuracy with such a high level of detail on catchment scale would be a tremendous advantage to soil scientists and environmental workforces in southern Africa. Future work should focus on DSM training, to broaden the base of DSM skills available in southern Africa. This will ensure that soil information would be included in addressing an increasing amount of real world problems at catchment scales.

Through a DSM approach, machine learning was used to predict the occurrence of soil forms and soil families in accordance with the South African Soil Classification System. A total of 591 soil observations were made at specific points, pre-determined with the conditioned Latin Hypercube sampling (cLHS) method. These pre-determined points were classified into nineteen soil forms and forty eight soil families. The soils were then further divided into nine soil groups, based on their inherent sensitivity to erosion. Outlier observations were omitted from the dataset to create a reliable framework to predict the soil groups as influenced by the SCORPAN factors. These soil groups were mapped and evaluated with an accuracy of 68% and a Kappa statistic value of 0.42 that compare well with other soil maps, both locally and internationally. Mapping soil with an acceptable accuracy with such a high level of detail on catchment scale would be a tremendous advantage to soil scientists and environmental workforces in southern Africa. Future work should focus on DSM training, to broaden the base of DSM skills available in southern Africa. This will ensure that soil information would be included in addressing an increasing amount of real world problems at catchment scales.
