- Description: Historically, placers of economic importance at Sibanye Gold's Beatrix No. 3 Shaft were Beatrix Reef, Aandenk Reef and Composite of the two reefs. Recently, the VS5 placer has emerged to be a significant contributor of ore tonnages mined on the Shaft as mining advances into deeper levels towards the northern portion of the mine lease area. Gold concentration in the VS5 Reef is highly variable from uneconomic, through marginal to economic gold values. A good knowledge of the sedimentological framework of the VS5 Reef was considered necessary in order to interpret the variable distribution of the gold within the VS5 placer. The aim of this study was to determine the depositional environments that played a major role during the formation of the VS5 placer by means of investigating the macroscopic sedimentological parameters of this particular reef. These sedimentological parameters were used as the basis for the subdivision of VS5 Reef into different facies recognized in the mine and surrounding areas. It was recognized that the VS5 placer was formed in a distal, braided fluvial environment by the reworking of the pre-existing Aandenk Reef by new materials containing significant amount of nondurable materials (see definition on page xii) such as shale detritus. Where there is no evidence of reworking of the older Aandenk Reef, the VS5 Reef occurs as poorly sorted, polymictic conglomerate with abundance of non-durable detritus. This is referred to as the Immature (IV) VS5 facies and occurs in the northern portion of the study area. The degree of reworking of the gravel bars by waves and current action resulted in the formation of well sorted, oligomictic conglomerates of the Beatrix facies in the southern portion of the mine. At the boundaries between the Immature VS5 and Beatrix facies occurs the Transitional (Sub-mature) VS5 facies, characterized by reef comprising a polymictic upper portion and a basal more mature oligomictic unit. The Transitional VS5 facies extends across the current central northern mining faces of Beatrix No. 3 Shaft with a northwest-southeast trend. There is a strong correlation between the VS5 lithofacies and distribution of gold mineralization. The Immature VS5 facies is poorly mineralized, with gold values averaging 200 c.m.g/t and lower. The Transitional (Sub-mature) VS5 facies has elevated gold values, ranging from 300 c.m.g/t to 1500 cm.g/t. Mineralization in this unit tend to be bottom loaded as well as at the base of each cyclic unit. The Beatrix facies records the highest grades averaging >1500 cmg/t. The improved understanding of the VS5 lithofacies made it possible to predict gold mineralization and aid planning to mine into viable VS5 areas.

- Description: The principal aim of this study was to assess the socio-economic contribution of nontimber forest product (NTFP) trade to households in Zomba and Machinga, southern Malawi. Quantitative and qualitative data were collected through several methods, including a household survey using questionnaire interviews, focus group discussions, key informant interviews with individual traders, direct observations, and literature review. The quantitative data were analysed statistically using SPPS version 16.0 while the qualitative data were analysed thematically. NTFP trade was the third important source of cash income for 15% of the households, although the level of use, buying and selling of NTFPs varied across the four study villages. All households in all the study villages used firewood (100%), and most used thatch grass (94%), bamboo (96%), wood for building (92%), largely as construction materials. However, the percentage of households buying NTFPs was lower, with the maximum percentage of households being 50%. The percent of households engaged in selling at least one NTFP was lower still at 39%. Substantial cash incomes were generated from firewood and edible orchids sales which provided up to a maximum of Mk180,000, equivalent to US$456, per year. Households joined the trade mostly for an alternative source of cash income due to poverty and to meet basic needs when other options were not available or feasible. Cash income generated from NTFP trade acted as a safety net and a coping strategy when other avenues supporting livelihoods were not accessible. The socio-economic benefits derived from NTFP trade were associated with the quantities collected, sold, market forces influenced by the law of demand and supply. The small amounts of cash income generated by most households were important as they supplemented household cash needs. There was a strong association between NTFP trade as one of the important sources of cash income and the number of months a household had food from their own garden in a year. There was a significant relationship though weak between ranking of NTFP trade and livestock ownership by households. Value chain analysis was used as an analytical tool to understand the processes involved in NTFP trade. The value chains for the products under study were short, dominated by traders and some intermediaries. Most of the products were sold in local markets with little value addition. This study recommends that policy makers should integrate NTFPs into their development plans, emphasizing the establishment of management strategies that will enhance availability and sustainability of the resource. NTFPs contributed to the livelihoods of the households socially and economically through provision of food, cash income, energy for cooking, medicine and construction materials.

- Description: In the context of rapid globalisation, skilled South African employees and professionals are often attracted overseas to take up new work opportunities in foreign countries. This may cause these individuals no longer to be “ordinarily resident” in South Africa. At the same time, changes in modes of travel, information and communication channels could result in companies and trusts no longer being considered to be tax resident in South Africa, if the place of effective management for these entities is moved to a foreign country and a double taxation agreement between South Africa and that foreign country deems these entities to be exclusively resident in the foreign country. The objective of this thesis was to analyse the tax implications that could arise when a resident natural person, trust or company ceases to be a resident or when a Controlled Foreign Company (CFC) ceases to be a CFC. A detailed analysis of the “exit charge” in section 9H of the Income Tax Act was undertaken to understand its normal tax implications when a natural person, trust or company ceases to be a resident or a CFC ceases to be a CFC. This included an analysis of how a natural person, trust or company ceases to be resident or how a CFC ceases to be a CFC. It was found that certain normal tax principles consistently apply to when a natural person, trust or company ceases to be resident or a CFC ceases to be a CFC. At the same time, certain unique normal tax implications arise for trusts and CFCs since they are impacted by the special tax rules that apply to these entities. Furthermore in the case of a trust, a judicial precedent has established that the “exit charge” remains and is taxable in the trust. For CFCs, there is uncertainty as to whether the “exit charge” could arise when a shareholder ceases to be resident, which results in residents no longer holding more than 50% of the total participation or voting rights in that foreign company.

- Description: The purpose of this study is to explore how Rhodes University (RU) students construct identity through the symbolic consumption of luxury branded clothing and the role played by reference groups in the consumption behaviour. The study employed the Social Identity Theory (SIT) as a theoretical framework which explains the underpinnings of the cognitions and behaviour with the use of group processes (Trepte, 2006). The central principle of SIT lies in individuals classifying themselves and others into in-group (reference groups) and out-group social categories respectively. There has been a gap in the literature pertaining to a full understanding of the identity construction process through symbolic consumption of luxury brands in South Africa (Reed, 2002). The significance of the study is to provide a foundation for an enhanced theory of consumer behaviour in this context. This study employed a qualitative research approach. A non-probability convenience sampling technique was used, and a total of 12 undergraduate and postgraduate students were interviewed. The chosen data collection method was semi-structured in-depth interviews and data were analysed using thematic analysis. The findings of the study revealed that participants consume luxury branded clothing for both functional and symbolic purposes. Various factors emerged that influence the choice of the symbolic consumption behaviour such as income, buying frequency, spending patterns, perceptions and habits around retail shopping and the shopping experience. In addition, results indicated that reference groups (celebrities, family and peers) play a significant role in the symbolic consumption and construction of identity among the participants. In addition, the results also indicated that the RU participants engaged in a ‘save to spend’ technique whereby they save their pocket money so that they spend it on their favourite luxury branded clothing when they leave for the holidays. There was a common reference group that emerged from the study, namely the peer in-group. The influence of reference groups on youth consumers in South Africa may assist with marketing strategies that can be employed when targeting the Generation Y. Additionally, results indicate that luxury branded clothing have an impact on identity construction within the South African context. The respondents tie their identity to their luxury branded clothing as an indication of ‘who they are’ and as an extension of the ‘self’.

- Description: This study evaluates the efficacy of the Bridges to the Future Initiative - South Africa 2 (BFI) tablet program on early literacy skills, as well as the ways in which learner-operated technology interacts with a traditional South African education system. The BFI is a curriculum-aligned early literacy development intervention implemented through technology in grades 2 and 3 in Northern Sotho1 first-language schools. A mixed-methods research design was utilized, involving three components: a literacy skills test administered through a time sequence trial design; a curriculum-aligned uptake and retention test using a pre-post design; and a qualitative research component including classroom observation, participant interviews and prompted drawings by learners. Paired sample t-tests show significantly higher gains during the treatment period in fluency and comprehension, and significantly higher gains in the control period in decoding individual words. It is theorized that this is due to teacher emphasis on emergent literacy. When initial ability is taken into consideration, all ability levels gain more on average during the treatment period in at least one measured skill. Regression analysis determines that time spent on the BFI program is not the most significant determiner of gains in the intervention period. Qualitative analysis supports this finding and suggests that program use cannot replace quality classroom practice in advancing literacy skills. Learners performed better after a delayed retention period than in an initial uptake test, indicating high rates of retention of knowledge gained through program use and traditional instruction, but inconsistent access to literacy skills gained.

The taxation of illegal income in South Africa: the basis on which proceeds from a unilateral taking should be taxed

- Description: In South Africa, income tax is levied in terms of the Income Tax Act, 58 of 1962, and the calculation of a taxpayer’s taxable income and ultimately the tax liability commences with considering what constitutes the taxpayer’s gross income. In terms of the definition of “gross income” a person can be taxed either on receipts or accruals. The definition makes no reference, however, to the legality of receipts or accruals. The main issue addressed in this thesis is the interpretation of the term “receipt” in relation to the proceeds from a unilateral taking (theft) and whether the concept of a receipt in relation to theft should be interpreted using the subjective approach used in MP Finance Group CC (In Liquidation) v C:SARS, or the objective approach. An interpretative research approach was used to provide clarity on the matter. The documentary data used for the research consists of South African tax legislation, case law, textbooks and journal articles. The thesis also analysed SARS’ view in Interpretation Note 80 that MP Finance Group CC (In Liquidation) v C:SARS is authority for a unilateral taking being a receipt, and the correctness of this viewpoint. A brief comparative analysis was done of the basis on which illegal income flowing from a unilateral taking is taxed in Australia, New Zealand and America. These countries have legislative provisions that specifically deal with how the proceeds from theft in the hands of a thief should be treated for tax purposes. The thesis concludes that, although the court in MP Finance Group CC (In Liquidation) v C:SARS shed some light on the issue of the taxability of income from illegal activities, the basis on which proceeds from theft may be taxed, as opposed to the basis on which proceeds from other illegal activities like fraud are taxed, remains a grey area in our law. The thesis recommends the introduction of a legislative provision in order to provide a more unified, consistent and effective approach when taxing all illegal income.

- Description: Syn-tectonic quartz veins formed along faults, folds and tension gashes in rocks of the Cape Supergroup (CSG) of the central Cape Fold Belt (CFB) comprise mainly hydrous saline fluids. These veins may also contain CO₂ Syn-tectonic quartz veins formed along faults, folds and tension gashes in rocks of the Cape Supergroup CO₂ , or CH4 and CO₂, or neither CO₂ nor CH4. The majority of inclusions are two-phase and fluid rich, and the most common fluid composition is H2O-NaCl. The final melting temperature, and therefore salinity, differs very little across different structures (fluids in all structures show maximum salinities between 2.5 and 6 wt% NaCl equivalent). Thrusts, reverse faults, strike- and oblique-slip faults, and folds all have similar homogenization temperatures (Th). Primary H2O-NaCl inclusions show Th between ~130 and 200 °C, and H2O-NaCl-CO₂ inclusions have slightly higher Th, between ~140 and 240 °C. Secondary inclusions in all structures have a similar Th range to primary inclusions, but have a lower maximum Th (~130-180 °C). Inclusions containing CH4 have the highest Th (~210 - 300 °C). Microthermobarometry indicates that fluids associated with contractional structures, such as thrust faults or folds, from the Ordovician lower Table Mountain Group (TMG) show lower greenschist facies trapping conditions (~170-175 MPa and ~240-300 °C). These veins also show a plastic deformation overprint (recrystallization of quartz and foam textures), at temperatures higher than the trapping conditions (~ ≥300 °C), indicating that temperatures increased subsequent to hydraulic fracturing, quartz precipitation and thrust slip. These structures formed on a prograde path, at approximately 335 Ma, at a time when the overlying CSG rock column was approximately 6800 m thick. This event pre-dated the thermal peak of the Cape Orogeny at ~276-261 Ma by ~60 million years. Further up in the stratigraphy of the CFB, in the Devonian upper Bokkeveld Group, fluid inclusions in quartz veins associated with a thrust fault show similar trapping pressure (~200 MPa) to the structures in the lower CFB. At 335 Ma, the stratigraphic overburden on this sample locality would not have been sufficiently thick to exert the calculated pressure. This fault may have formed at a later time. The observed pressure of ~200 MPa may have been created either by the higher Bokkeveld Group, the entire Witteberg Group, and further CSG rocks that were eroded prior to the deposition of the Permo-Triassic Karoo Supergroup, or by tectonic thickening of the CSG by prograde thrusting. Still further up in the CSG, fluids from a fold sample from the Witteberg Group record quartz precipitation at lower greenschist facies conditions and subsequent plastic deformation during folding. The formation of this fold postdates the thrusting in the lower TMG, and may correlate in time with deformation during the thermal peak in Middle Permian time (~276-261 Ma).

- Description: In most South African schools Grade 12 Physical Sciences learners are generally not performing well. As Examiners’ Reports reveal, they are particularly weak on the topic of electrical circuits. Because of this, the Examiners recommended that conventional practical activities and revision should be implemented to improve learners’ performance whilst they are in Grade 11. These factors contributed to the rationale of this study in using the ‘straw electricity’ analogy in conjunction with a conventional practical activity to mediate learners’ sense making of Ohm’s law. The study falls within the interpretive paradigm, whose focus is on the understanding of human world-views. Within the interpretive paradigm a qualitative case study approach was employed. It is a case study because it aimed to investigate a group of learners in a given context. This qualitative case study used purposive sampling to select participants. Various data gathering techniques were employed, namely, documents, observations and stimulated recall interviews. The gathered data was analysed so as to determine the indicators of how learners made sense of Ohm’s law. The findings of this study are that learners were able to construct new knowledge within a social context where the ‘straw electricity’ analogy, using easily accessible resources, was incorporated in tandem with a conventional practical classroom task. Moreover, the ‘straw electricity’ analogy enabled a better understanding of science concepts as it tested and supported different learning skills.

- Description: Thermoluminescence of synthetic quartz annealed at 1000 ºC for 10 minutes has been studied. The aim was to study mechanisms of thermoluminescence in annealed synthetic quartz and to discuss the results in terms of the physics of point defects. The sample was irradiated with a beta dose of 10 Gy of beta radiation and then heated at a linear heating rate of 1 ºC.s-1 up to 500 ºC. The thermoluminescence (TL) glow curve consists of three glow peaks. Peak I at 74 0C (main peak) with high intensity as compared to the other two peaks. Peak II at 144 ºC is more intense than peak III at 180 ºC. This study was on the main peak (MP) at 74 ºC and peak III at 180 ºC. Kinetic analysis was carried out to determine the trap depth E, frequency factor s and the order of kinetics b of both peaks using the initial rise, peak shape, variable heating rate, glow curve deconvolution and isothermal TL methods. The values of kinetic parameters obtained were around 0.7 to 1.0 eV for trap depth and in the interval of 108 to 1015 s-¹ for frequency factor for both peaks. The effect of heating rate from 0.5 to 5 ºC.s-¹ on the TL peak intensity and peak temperature was observed. Also the effect of thermal quenching was observed at high heating rates. Since the TL glow curve has overlapping TL peaks, the Tm-Tstop method from 54 ºC up to 64 ºC and E -Tstop methods were introduced where a first order single peak was observed. Phototransfered thermoluminescence (PTTL) was investigated and characterized by three peaks. First PTTL peak I at 72 ºC, peak II at 134 ºC and peak III at 176 ºC. Analysis was carried out on peaks I and III for the effect of dose dependence from 20-200 Gy. Thermal fading was observed on PTTL peaks I and III, after storage time of 30 minutes.

- Description: These Aesthetics Are Not New draws inspiration from the effect of digital technological progress on a consumer society. The Internet as a source of ubiquitous imagery reaffirms the idea that in a Post-Internet age there is nothing new, only conditions affected by a networked way of life. In this thesis I attempt to question contemporary ideas of representation and art making, specifically within the medium of oil paint, in a digitally consumed culture of instantaneous access. I interrogate the repetitive imagery that pervades our online experiences, and I speak about how I use my grasp of painterly knowledge and lexicon to replicate digital conditions in the real world to further cement my position that contemporary aesthetics, (digital, physical or both) are not new. I first introduce the reader to the idea of the Post-Internet, exploring the digital’s encroachment on our physical spaces and it’s relation to the politics of the medium of Oil Paint. I then address the concept of the Image-Object, and unpack this idea by comparing and contrasting emoji’s in relation to gestural mark making and the ascription of meaning through iconographic methods in Oil Painting. This culminates in an analysis of my physical practice in relation to these ideas, and concludes with my observations on the future of our ways of seeing, as affected by the Internet and technological progression.

- Description: The Eastern Cape of South Africa is characterised by water scarcity, constraint on usage, and inter-basin transfers. Water from the Gamtoos River catchment supplies water users both within the catchment and outside the catchment boundaries. This requires careful management of water and land to prevent overexploitation. However, management is complex as it is divided among various stakeholders with differing interests. Political geoecology is an approach that has the potential to provide holistic insight into the catchment’s water context. It was proposed to account for spatial patterns underlying interrelationships between resource distribution, human productive activity, and power relations by integrating the fields of political ecology and geoecology. This research was undertaken to further develop political geoecology as an approach for examining human-environment relations in geography through a case study of land and water management in the Gamtoos River catchment and its subcatchments. Distribution of resources and human influences were elucidated through generation of maps. To facilitate spatial analysis, the study area was delineated into catchment zones. Additionally, stakeholders were identified and classified at local, regional, national, and international levels. Power relations between stakeholders were investigated through qualitative content analysis of transcribed semi-structured interviews and survey questionnaires that were administered to 34 research participants (selected through purposive and snowball sampling) directly involved in resource management in the catchment. Findings were spatially interpreted for each of the zones. The source zone was characterised by natural vegetation, steep, rugged topography, limited access ability, and power relations around restoration and conservation interests, which arose most significantly in the Baviaanskloof. The natural recapture zone was characterised by irrigated cultivation in areas of less harsh terrain in the upstream (Baviaanskloof and Kouga) sub-catchments. In the marginal Baviaanskloof, localised power relations over water distribution primarily arose. In the thriving commercial farming context of the Kouga, power relations included a local upstream-downstream legal conflict, competing levels of governance, issues with establishing water users’ associations (WUAs), and lack of adequate implementation of processes by government. Regional power relations are most prominent in the thriving commercial farming context of the overlapping regulated recapture and final use zones in the downstream Gamtoos sub-catchment. The reliance on upstream sub-catchments and tensions with the city of Port Elizabeth over water use are mediated through decisions made at the national level. Non-location specific power relations included indirect influence through energy, markets, and standards organisations, barriers in government preventing successful process implementation, and equity issues (particularly limiting the success of emerging farmers). These results illustrated that resource distribution, human productive activity, and power relations combine to produce unique characteristics in each of the zones in the Gamtoos catchment. The application of political geoecology in this case study situated the approach as useful for examining human- environment relations in geography.

- Description: Baited remote underwater stereo-video systems (stereo-BRUVs) were developed to determine fish abundance and size structure in a more unbiased, and relatively non-invasive manner across a broader range of depths and habitats than conventional sampling methods achieve. These characteristics make stereo-BRUVs particularly useful for research inside marine protected areas (MPAs) where researchers are required to minimize disturbance to the protected environment. Although stereo-BRUVs have been widely used around the world, they are novel to South Africa and standardised protocols for their application are required. As such, this study aimed to address i) the effect of different bait types, namely pilchard (Sardinops sagax), squid (Loligo reynaudi) and bivalves (Crassostrea gigas and Perna perna) on the observed reef fish assemblage structure and ii) the effect of artificial illumination (lighting) on the observed reef fish assemblage structure sampled with stereo-BRUVs. One key component of the stereo-BRUVs methodology is the application of bait to attract fish into the field of view. Globally, pilchard is the most often used bait type for stereo- BRUVs, however, its suitability has never been tested comparatively against other bait types for South African conditions. Significant differences in fish abundance and assemblage structure were recorded between stereo-BRUVs deployments when applying the different bait types. The bivalve baits, oyster and mussel, were typically poor when sampling the reef fish assemblages of the region. Pilchard and squid were sampled in similar communities and were able to attract the majority of the reef fish from the region, suggesting they are suitable bait types for stereo-BRUVs in the Agulhas ecoregion. However, a power analysis indicated that roughly twice the amount of samples are required to effectively sample the same abundances of Chrysoblephus laticeps (roman) and Cheilodactylidae (fingerfins) species when sampling with squid as opposed to pilchard. Both bait types can be locally sourced, however, squid is considerably more expensive than pilchard. Considering the difference in cost, together with the fact that twice as much squid bait is required, squid is not a cost-effective option relative to pilchard. As such this study recommends that pilchard is the most appropriate bait for the Agulhas ecoregion of South Africa. Due to low light levels, artificial lighting is required when conducting remote video research in the sub-photic zone. Blue light has a shorter wavelength than other colour lights and attenuates slower through water. In addition, blue lighting has no recorded effect on fish behaviour and has proven to be a successful light colour for underwater sampling. The use of lighting is unavoidable for sub-photic stereo-BRUVs sampling and is recommended for all stereo-BRUVs sampling for comparability of data from environments characterised by different light levels. A study was conducted to test the necessity of artificial lighting when sampling from environments characterised by ambient light levels adequate for stereo- BRUVs sampling, a comparative to measure the effect of light on the fish assemblage structure. Of the more commonly detected fish species (those observed in >50% of the samples), most were seen at similar abundances in samples using lighting and in those without lighting. No significant differences were observed in fish length data between samples collected with and samples collected without lighting. This suggests that standardised stereo-BRUVs sampling across photic zones on the continental shelf of South Africa can be collected without blue lighting when ambient light levels are sufficient to see the survey area.

I will aim to construct an account that is value driven rather than nature driven as it seems that this is where the problem lies. In order to do this I will assess two current accounts of understanding and show that they cannot adequately explain the value that we give to understanding, nor do they explain how we understand.

- Description: The world is becoming increasingly complex and uncertain due to increasing levels of social- ecological change. Rural communities in sub-Saharan Africa are faced with multiple interconnected challenges such as population growth, environmental change, economic recession and climatic changes, amongst others. Such challenges can play a key role in determining vulnerability and food security, particularly for natural resource product- dependent societies that have limited livelihood sources. Studies that consider understanding how society and ecosystems simultaneously interact and respond to new and exacerbated drivers are increasingly needed. Therefore, this study was conducted in Fairbairn village, Eastern Cape, South Africa with the purpose of exploring multi-scale historical processes and current related trends in livelihood and environmental change, and the implications for future trajectories under a changing climate. This study applied social-ecological thinking and several conceptual approaches were combined to provide a lens for exploring the changes taking place. These included, inter alia, complexity theory, social-ecological systems, the sustainable livelihoods approach and the Intergovernmental Platform on Biodiversity and Ecosystem Services framework and principles. The study employed a mixed method approach to gather data, which included a household survey, aerial photography, historical records as well as Participatory Learning and Action, focus group discussions, and Participatory Scenario techniques. Quantitative data were analysed using Excel and Statistica version 13, whilst coding was used for thematic analysis of qualitative data. The main objective of this study was to explore multi-scale historical processes and current related trends of livelihood and environmental change, and the implications of these for future trajectories under a changing climate. Livelihood and landscape changes in Fairbairn village are embedded within a history of direct state intervention and more recently, improvements in basic service delivery. The findings show that natural resource products still form an important part of people’s livelihoods despite many other changes over the last fifteen years. A high proportion of households continue to utilise different products to meet household needs. The most widely used products are fuelwood, wild herbs and wild fruits. More so, my results revealed a significant increase in the number of people commercialising natural resource products over the past fifteen years. Furthermore, I found that rural livelihoods in Fairbairn are heavily dependent on external income and consumption and have become increasingly divorced from local production patterns. My results depict a steady decline of cultivated fields with a corresponding increase of home gardens since the 1960s. Therefore, the results demonstrate that current livelihood strategies are an expression of historical processes interacting with current contextual complexities. Given the complex and multidimensional issues at play in Fairbairn, the study highlights that there is no straightforward answer regarding future livelihood strategies. However, participatory scenario deliberations revealed that the youth were much more open to diversified and even very different forms of livelihood strategies in the future, whilst community leaders and elders remained firmly attached to farming activities. Understanding the diversity of past livelihood changes, together with current trends, can help to better contextualise future livelihood trajectories and this can therefore help rural communities identify and avoid undesirable futures under a changing climate.

- Description: This thesis examines the link between social movements with the legal system to enforce human rights within the public health sector in regards to access to HIV and AIDS-related disease treatment. Research shows large scale incapacity for the provision of such essential medications within the public health sector; this is not merely an issue for those in the developing world. This thesis demonstrates that it is an issue that is faced by those using the public health sector services to access essential HIV and AIDS medications and it shows that certain people are unaware of their human rights to have fair and equal access to such essential medications. Although there is abundant research studies on HIV and AIDS in South Africa, there is a lack of studies that look into the impact that social movements have had in strong-arming, to a certain extent, the government in holding it accountable for infringing its constitutional promises to all citizens. This thesis is set against a backdrop where, the crisis of lack of access to essential medications in the public health sector which is closely intertwined with the collapsing health care system and it is combined with the issues of international patent policy for essential medication and developing countries like South Africa, who are trying to tackle this hurdle straight on. This thesis argues that the social injustices of rights violations integrated with the issues of international patent laws aggravate the access to essential medications in the public health sector in the country. This thesis adopts the use of a Rights-Based Approach, which is built on the foundational understanding that at the centre the focus is on human rights. In using the rights-based approach the intention is to outline ways in which to improve and further develop the ability of individuals and communities to recognize their rights. The findings show that the important factor of using a Rights- Based Approach is that it puts the pressure on the state to legitimately fulfil its obligation to its people. Thus the thesis evaluates the use of combining the legal system to enforce human rights and the role of social movements to realize the right to health for South Africans that use the public health sector to access essential HIV and AIDS antiretroviral drugs. This research paper shows that the Treatment Action Campaign and Section27 have contributed to the recent transformation of the public health sector in South Africa. They have achieved this through the implementation of rights-based education campaigns as well as HIV and AIDS education particularly geared for those that use the public health sector facilities, to attain access to essential medications; not only for HIV and AIDS but also for tuberculosis and other AIDS-related disease treatment. The thesis further highlights that the Treatment Action Campaign and Section27 have assisted in greatly improving the access to HIV and AIDS essential medications for prevention of Mother to Child Treatment Programs. The findings of the research paper outline that the main issue lies in the fact that even though essential medications for HIV and AIDS are now more available, the medical infrastructure is one of the main problems accounting for the lack of service delivery of these essential medications in the country’s public health sector.

- Description: The aim of this study is to investigate why well planned policies are not getting implemented as intended. The study was conducted in the offices of Amathole District Municipality (ADM) in the Eastern Cape Province, including the cooperative project in Alice as one of the projects that was coordinated by the ADM. Concerning the research design and methodology, a qualitative research design was used. The data collection process involved conducting unstructured interviews with the officers from the Amathole District Municipality office (the ADM officers / the municipality officers) and the members of cooperative projects (cooperatives/projects). Mainly, an ethnographic approach was used; it involved embracing participant observation in the ADM offices for approximately 6 months. As the researcher, I participated as one of the ADM’s officers in different activities, namely: attending meetings and one workshop, and accompanying the development officer while conducting an observation of various projects in Butterworth. The findings in the study disclose that the disjuncture between policy planning and implementation may be attributed to 4 factors, which are associated with the ADM office as the development agency for the Amathole region. These are: the incapability to respond to policy implementation complexities, failure to exploit policy implementation complexities as learning opportunities, the insufficient understanding of ‘process monitoring’ as a tool that could be integrated in projects management, as well as the execution of policy implementation in the absence of policy documents as a guide in implementation processes. Moreover, these factors are examined as being related to each other, and they will be discussed in detail in the course of the thesis.

Unity and diversity, love and conflict: an exploration of the philosophy of life in C.S. Lewis’s Cosmic Trilogy
- Authors: James, Michael William

- Description: The subject of this thesis is to explore the philosophy of life that informs C.S. Lewis’s Cosmic Trilogy (Out of the Silent Planet, Perelandra and That Hideous Strength). These texts are “spiritual adventures” which exemplify Lewis’s phenomenology of spiritual progress - the movement from self-centredness to Other-centredness. I perform a close reading of the trilogy and attempt to understand the way(s) in which the three major thematic threads - Conflict, Love, and the relationship between Unity and Diversity - all contribute to the proposed phenomenology of the spirit. In the final chapter, I use Kierkegaard’s “stages in life’s way” (the aesthetic, ethical and religious) as a structural frame for understanding the trilogy’s dialectical movement. I also take the unusual step of codifying the fruits of my exploration into what I call ‘the Cosmic Manifesto,’ which serves as my creative engagement with the results of the philosophical exploration. My research shows that the philosophy of life is expressed through a tripartite spiritual journey. The traveller firstly visits the sphere of Mars, which entails developing clear perception and overcoming fear of the Other. Next, the traveller must pass through the sphere of Venus, where - through courageous action on behalf of the Other - s/he learns the nature of self-sacrificial love. Successfully traversing these two stages, the traveller then apprehends the spirit of Harmonia, the love-child of Mars and Venus. As a result, the ideal relation between the self and the Other - unity in diversity - is discovered. I conclude that the philosophy of life underlying the trilogy is both aesthetically, ethically and religiously rich, and is an insightful perspective on a “life worth living.”

Walking the Spatial Triad: how do Rhodians experience Rhodes University as a place?

- Description: Globally and locally the documentation of the experience of the tertiary education institution as a place in the human or cultural geography sense of the word is an under-utilised academic exercise. Locally, however, with the 2015 #RhodesMustFall moment which highlighted South Africa's tertiary education institutions as places of meaning and accompanying experience, the documentation of such overlooked place experience became ever more pressing. The purpose of this thesis is to document how some members of the population of one South African tertiary education, the Rhodians of Rhodes University, experience that university as the place that it is to them. This is a phenomenological documentation of experience as the thesis makes it a point to look at a selection of Rhodians and their experience of emplacement in the place that is Rhodes University. In-depth mobile interviews, closely related to transect walks, were conducted with 12 Rhodians randomly selected in the hope for maximum sample variation. The interviews were conducted with the aid of a camera recording each participant’s daily transit route through campus as they reflected on their experience of Rhodes University as the place it is for them. The thesis finds that the experience of Rhodes University as a place is highly informed by the university's built and decorated environment being a visual experience that is both walked through as part of living in the place, and wherein people find themselves engaging in social relations with other Rhodians. The thesis also finds that the experience of Rhodes University as a place is also highly informed by previous experiences of places as visual and social activity entities - that the participants bring other places with them into this place. The Rhodians who participated in this research experience the placeness of Rhodes University as an emplacement that is part old, part modern, part intrigue, and part contest. Socially the university is found to be both challenging and negotiable in line with what the individual Rhodian is and is not willing to do in accordance with their emplacement and its social demands. Ultimately, the experience of Rhodes University as a place is highly determined by the individual Rhodian's past experiences of emplacement and the expectations that they bring with them which shape what their present place is to them.
