- Description: The construction industry is one of the most dangerous industries in the world, with many workplace fatalities every day. The existence of legislation that governs Occupational Health and Safety (OHS) is an intervention to ensure that all governments, employers and employees play their part in establishing and implementing policies that will help secure healthy and safe working environments. The study is qualitative and with the help of an interview guide, semistructured interviews were used to collect the data. The respondents were selected using purposive and snowball sampling methods. Ten managers from ten (five small, five large) construction firms, two employees from each firm, and the OHS inspector from the Department of Labour in Grahamstown were interviewed. Having explored management’s practices, communication methods, training and distribution of information, employee representation and participation, and industrial relations, several conclusions were reached. During the study it was found that there are a number of obstacles that are hampering effective OHS in the construction industry. Some of these include; management’s lack of commitment to a participatory approach in OHS decision-making, limited resources to invest adequately in OHS, and the lack of sufficient trade union involvement. In addition, we know very little about OHS in the construction industry, and the mere existence of OHS legislation does not help reduce the risks associated with construction work, especially when there is a shortage of skilled personnel to enforce the legislation and regulations.

- Description: The education system in Namibia was shaped by the policies located within the framework of the apartheid ideology. Since it gained its independence in 1990, the government positioned education at the top of the national priorities. Thus, there has been a growing realisation of the importance of more democratic forms of leadership in the education system for the country to be able to cater for a democratic society. Amongst others, teachers became active creators and managers of the learning outcomes. In addition, teachers are regarded as agents of change and the driving force for productive teaching and learning. Literature describes how the management in schools has been redistributing authority and power so that a culture of teacher leadership in school communities can grow. More importantly, school improvement depends more on the active involvement of teacher leaders as it is realised that people in formal positions cannot do everything. In this line this study investigated the understanding of teachers and members of management of teacher leadership practice and it further identified the structural and cultural factors which enabled and inhibited this practice in a primary school. This study is a case study of a Primary school in a semi-urban area of Otjozondjupa Region, a central part of Namibia. This study was conducted in the interpretive paradigm and it is a qualitative case in nature, employing semi-structured interviews, observation and document analysis. Triangulation over the data revealed that respondents have an understanding of the concept and that all teachers are involved in leadership roles at school which are more strongly found in the classroom and through involvement with other teachers. Teacher leadership roles at the case study school also occur within the whole school with some limitations and also extend beyond the school. Grant’s (2008) model of teacher leadership was used to analyse the data. The study suggested some hindrances and supporting factors of teacher leadership. The findings suggested that teacher leadership is understood at the case study school and that they experienced factors that enabled and hindered this practice at different stages. Enabling factors included the school structure, further studies and workshops attended, while teacher leadership is impeded by teachers’ unwillingness to collaborate with others and the platoon system. The study recommends future large scale studies, including at secondary schools, so that a broader sense of teacher leadership may emerge.

- Description: Gold exploration in the laterite terrains of the Siguiri basin (Guinea-West Africa) is discussed in this thesis. It seeks to propose and develop effective and reliable geochemical exploration techniques applied in such laterite terrains. The study is also intended to investigate and provide some geological clues as to why, in some target areas, the reconnaissance test drilling across the geochemical anomalies couldn’t intersect economic gold mineralisation. Targets were generated based on soil geochemical results, some of which were drilled without delivering economic discoveries even on areas with strong and consistent geochemical signatures. To find the failure and define the appropriate methods to be used is the core of the thesis. More importantly, the geological observation is aimed at sourcing and establishing the nature and validity of geochemical anomalies within the license area and their relationship with the underlying lithologies and structural networks. The geological field work conducted during this study is mostly based on regolith and surface geological mapping. The thick laterite cover, deep weathering, bedrock geology, gold geochemistry (the gold geochemical anomalous results are defined according to historical data before 2007), soil formations and variations in climate conditions are emphasized to illustrate the importance of mineral element mobility and dispersion in the weathering profiles. The knowledge and experience in regolith geochemistry and regolith mapping provide the advantage to exploration geologists. The depletion of ore resources and reserves in Siguiri and the continuous decline of the gold price in comparison to the complexity of exploring for gold are demanding more scientific-related thoughts and techniques to be integrated in the available geological, geochemical and geophysical information so as to reduce costs. The integration of good exploration strategy and technique may result in the possibility of making viable discoveries in this highly competitive geological environment where the mineral resources become depleted every day.

- Description: Water quality deterioration is reaching crisis proportions in South Africa. Many South African catchments are over-allocated, and decreasing volumes of source water mean increasing concentrations of pollutants. The Crocodile River Catchment in the Mpumalanga province in South Africa was identified through previous research, as a catchment faced with deteriorating source water quality for water users in the catchment. Poor source water quality has become a sufficiently acute concern for the stakeholders in this catchment to co-operate in developing a process that assists with compliance control of their water use and waste disposal to reduce costs, decrease industrial risks as water quality compliance increases, and improve source water quality. The sugar industry is downstream within the Crocodile River Catchment, and is affected by the activities of all upstream water users; the industry is thus dependent on the stakeholders upstream participating in the effective management of the resource. However, the sugar industry is also located just before the confluence of the Crocodile River and Komati River upstream of the Mozambique border, and thus the water quality of the sugar industry effluent will affect the quality of the water that flows into Mozambique. The sugar industry is on the opposite river bank to the Kruger National Park, which has high water resource protection goals. Therefore, the sugar industry has a national role to play in the management of water resources in the Crocodile River Catchment. This study provides a focused view of the role of the sugar industry in the development of a co-operative, integrated water quality management process (IWQMP) in the Crocodile River Catchment. In order to address the objectives of this study, this research drew from an understanding of the social processes that influence water management practices within the sugar industry as well as social processes that influence the role of the Inkomati-Usuthu Catchment Management Agency as the main governing institution in water resource management in the Inkomati Water Management Area. The study also drew from an understanding of scientific knowledge in terms of a water chemistry which describes the upstream and downstream water quality impacts related to the sugar industry. The water quality analysis for the Lower Crocodile River Catchment shows a decline in water quality in terms of Total Dissolved Solids (TDS) loads when moving from below Mbombela to the Mozambique border. The major sources of TDS in the Lower Crocodile River are point source dominated, which may be attributed to the extensive mining, industrial and municipal activities that occur across the catchment. When observing Total Alkalinity (TAL) and pH values from below Mbombela to the furthest monitoring point, there is deterioration in the quality of the water in the Lower Crocodile River, with the Kaap River contributing a negative effect that is diluted by the Crocodile main stem. The Hectorspruit Waste Water Treatment Works (WWTWs) (located in the Lower Crocodile River Catchment) contributes high concentrations of TDS and TAL into the Crocodile River. Total Inorganic Nitrogen and Soluble Reactive Phosphorus concentrations decrease in the lower reaches of the Crocodile River compared with the river below Mbombela, which can be attributed to the extensive sugar cane plantations located in the Lower Crocodile River Catchment acting as an “agricultural wetland” that serves a function of bioremediation resulting in large scale absorption of nutrients. This is an interesting result as earlier assumptions were that fertiliser application would result in an overall increase in nutrient loads and concentrations. Biomonitoring data show no substantial change in aquatic health in the LowerCrocodile River Catchment. For a catchment that has an extensive agricultural land use in terms of sugarcane and citrus production, the Crocodile River is unexpectedly not in a toxic state in terms of aquatic health. This is a positive result and it suggests that pesticide use is strictly controlled in the sugar and citrus industry in the Crocodile River Catchment. For long term sustainability, it is essential for the sugar industry to maintain (and possibly improve) this pesticide management. The social component of this study aimed to provide an analysis of the management practices of the sugar mill as well as examining agricultural practices in the sugar cane fields in relation to water quality management through the use of Cultural Historical Activity System Theory (CHAT). This component showed that there are contradictions within the sugar industry activity system that are considered to be areas of “tension” that can be loosened or focused on to improve the contribution the sugar industry can make to the IWQMP. Surfacing contradictions within the sugar industry activity system and the Inkomati-Usuthu Catchment Management Agency activity systems highlighted areas of potential for learning and change. While an understanding of biophysical processes through scientific knowledge is critical in water management decision making, it is evident that an understanding of other actors, institutions and networks that inform water quality management decision-making also plays a significant role. The notion of improving the role of scientific or biophysical knowledge in contributing to socio-ecologically robust knowledge co-creation, decisions and actions towards resolving water quality problems is emphasised. Specifically, moving towards improving interactions between scientists and other actors (water users in the Crocodile Catchment in this case), so that scientific practices become more orientated towards societal platforms where water quality management is tackled to enable improved water quality management practices. Therefore, linking the social and biophysical components in this study provides a holistic understanding of how the sugar industry can contribute to the development of an IWQMP for the Crocodile River catchment.

- Description: This qualitative study focuses on business level strategy adopted by Twizza to compete in the bottom of the pyramid market in the Eastern Cape, South Africa. Twizza enjoyed huge success between the years 2010 - 2014 as a medium to large sized manufacturer of carbonated soft drinks in the Eastern Cape. In light of this, the current study seeks to answer the following: What business level strategy did top management at Twizza adopt to compete and grow in the BoP market in the Eastern Cape, South Africa? The study takes the form of a case study to explore and understand the patterns of decisions adopted by Twizza’s top management in competing at the bottom of the pyramid. As such, the main objective of the study was to identify the business level strategy adopted by Twizza which enabled their superior performance within the BoP market. The study adopts Porter`s typology to explore business level strategy. Stratified, purposive sampling was used to identify 4 top managers as participants in this study. A total of 7, semi-structured, interviews were used to collect critical incidents from top management of Twizza. This was the primary data used in this study. This type of data was combined with relevant information which was gathered via published press articles and on-line commentary. The study found that central to Twizza’s business strategy were four pillars, namely, strict control and management of manufacturing costs, product quality equal to that of market leaders, the ability of the organisation to manufacture its own raw materials and ability to ensure product availability to the market to the market. These findings reveal that Twizza employed a hybrid strategy, anchored by cost leadership. Thus, Twizza incorporated elements of differentiation and best value strategies to offer its customers affordable quality.

- Description: There is a considerable body of literature on the challenges faced by learners who speak an African language at home but who are taught through the medium of English. Less research has focused, however, on contexts where isiXhosa-speaking learners have Afrikaans as their Language of Learning and Teaching (LoLT), especially in Foundation Phase classrooms where teachers may not speak their learners’ home language. Such learners face the triple challenge of simultaneously learning a second language, learning to read in that language, and also learning new content and concepts through it. Using a multiple case study design, this investigation explores the mathematics teaching practices of Afrikaans-speaking Grade 3 teachers teaching isiXhosa-speaking learners through the medium of Afrikaans. Separate contextual profiles of the teaching practices of the participating teachers at the three schools are presented. Data were derived from school, classroom, and lesson observations (at least five complete mathematics lessons of each teacher), plus interviews with the teachers and with their school principals. By drawing on Vygotskian sociocultural theory and the interactive model of second language acquisition, this study highlighted the teaching practices of the three teachers as they mediated their learners’ mathematical conceptual development. An inductive data analysis approach was used to isolate recurring themes and patterns. Four main themes were identified: structuring of teaching and learning, facilitating of interaction, language use and implementation of mediating strategies. Analysis of the data shows that all three teachers’ language use displayed high levels of modified input, and high levels of context-embedded support. The levels of scaffolded learner talk were, however, found to be much lower than the levels of teacher talk, especially as far as academic registers were concerned. The teachers’ mediation strategies also displayed high levels of teacher-directed input which, on the whole, did not provide optimal opportunities for learners to develop independent levels of academic discourse. The study highlights the need for further research to inform teacher education and development with regard to more effective support structures to assist teachers with the sorts of challenges outlined above.

- Description: Section 11(a) of the Income Tax Act 58 of 1962 entitles taxpayers to a deduction in respect of expenditure actually incurred, provided that all the other requirements of section 11 and section 23 of the Act have been met. A company may issue its own shares, credited as fully paid up, as a payment for trading stock or services rendered, as was the case in C:SARS v Labat Africa (2011) 74 SATC 1. The question that was raised by this decision is whether the issue of shares constitutes “expenditure” as contemplated in section 11(a) of the Act. It is trite that a share in a company is a bundle of rights which entitle the holder to dividends when declared and to a vote in shareholders’ meetings and that a share does not come into the hands of a shareholder by way of transfer from the company, but is rather created as a bundle of rights for him in the company. In C: SARS v Labat Africa, the Supreme Court of Appeal decided that to issue shares as a payment for goods is not expenditure as contemplated in section 11(a) of the Act. The Act does not define “expenditure”. It has been interpreted in certain cases as a payment of money or disbursement, while it has been interpreted as the undertaking of a legal obligation in other cases. The Labat Africa case has been criticised for its interpretation of expenditure on the grounds that it is contrary to the principle that “actually incurred” does not mean “actually paid”. This research has argued that, in the context of the Labat Africa case, which related to an issue of shares in payment for goods, Harms AP’s judgment was concerned with showing why a share issue is not expenditure. He could not have intended to deny a deduction to transactions such as credit purchases.

- Description: The underpricing of initial public offerings (IPOs) and their subsequent low long-run performance represents one of the anomalies observed in primary markets worldwide. However, the depth and breadth of it varies from country to country, and sector to sector. Literature has documented that the phenomenon surrounding the long-run post issue performance of IPOs is not unique and that quite similar patterns can be found regarding firms making seasoned equity offerings (SEOs). This study is an empirical analysis of public equity offerings listed on the Johannesburg Stock Exchange (JSE). Using data for 141 South African IPOs that were listed on the JSE Mainboard from 2001 to 2010, significant short-run underpricing is found. A sector wise analysis of three broad sectors indicated that the ‘other’ sector had the largest IPO underpricing after the first few days of trading. The year-wise analysis is also documented. In the long-run this study showed that IPOs in South Africa underperformed two out of three benchmarks in 36 full months post listing. In contrast, using data for 50 South African SEOs during 2003 to 2010, superior SEO performance is found over a 36-month period when assessed using a size and industry adjusted benchmark. Various cross-sectional and time-series patterns in the aftermarket performance of IPO and SEO firms are also documented

Head of state immunity under the Rome statute of the International Criminal Court: an analysis of the contemporary legal issues and the African Union’s response to the prosecution of African heads of state

- Description: This research examines the impact of head of state immunity on the relationship between Africa and the International Criminal Court (ICC). Thus, it investigates the position of heads of state immunity before international criminal tribunals with special regard to the ICC and assesses the response of African States Parties to the Rome Statute of the International Criminal Court (Rome Statute) to their cooperation obligation under article 98 (1). In addition, it seeks to ascertain the extent to which the African Union (AU) decisions impact on the decision of African States Parties to the Rome Statute to cooperate with the ICC and determine the legality of Article 46 bis of the Protocol on Amendments to the Protocol on the Statute of the African Court of Justice and Human Rights (the Amendment Protocol). Thereafter, it appraises the possible impact of these developments on the application of the principles of international criminal justice in Africa and finally, makes recommendation on ways in which the AU-ICC relationship can be improved. The thesis begins by discussing immunity as a rule of customary international law and the exceptions to its application with regard to international criminal law. This paves way for the analysis of the cooperation regime of the ICC and exceptions thereto with special focus on immunity under article 98 (1) of the Rome Statute. The factors arising from the AU decisions relating to cooperation with the ICC are also discussed with a view to determine their justification under international law. The thesis draws on examples from Chad, Kenya and Malawi to illustrate the manner in which African States Parties to the Rome Statute respond to their cooperation obligation and to what extent this response is affected by the AU position. Lastly, the position of article 46 A bis of the Amendment Protocol, which safeguards immunity based on official capacity, is analysed with a view to determine how the introduction of this new provision is likely to affect the application of international criminal law in the African continent. Drawing on the study of the issues above, the thesis comes to the following conclusions. First, the application of immunity before a particular tribunal depends on the factors influencing its establishment and its mandate as provided for in the constitutive instrument. Secondly, states parties to the Rome Statute can rely on article 98 (1) to deny the ICC request for the arrest and surrender of President Bashir because he is the head of a non-party state. Thirdly, the AU’s position does not have a direct impact on the decisions by African States Parties to the Rome Statute on the issue of the arrest and surrender of President Bashir to the ICC. Fourthly, some of the AU grievances against the ICC have justification in international law and therefore deserve the attention of the ICC and the international community. Fifthly, article 46 A bis is in line with the principles of international law on immunities. Given these findings, the thesis recommends that the AU-ICC relationship should be mended in the interest of international criminal justice. And that this can be done by: strengthening the capacity of African States and Africa as a region to deal with international crime occurring in Africa; forging a deeper cooperation between the AU and the United Nations Security Council (UNSC) in ICC related matters; and by the ICC adopting a broad interpretation of its discretion during the prosecution of heads of state. This would allow the ICC to mete out justice without jeopardizing the proper functioning of the states whose heads are on trial.

- Description: The present study provides the results of detailed mapping and analysis of structures encountered in Seguelen pit of Siguiri gold mine, Guinea, where the Siguiri mine is geo-tectonically located in the Baoulé-Mossi domain of Man Shield in West African craton. The gold deposit is hosted in low-grade metamorphic sediments of turbidites sequences which form part of the Lower Proterozoic of Birimian Super group. Three rock formations of Balato, Fatoya and Kintinian underlay the overall pits. The Siguiri gold mine is characterized by the deep weathering profile, developed over the rocks reaching 200 m below the surface in some areas and often capped by the lateritic gravel or duricrust. The rock formations at Seguelen area are characterised by strong bedding monotonously dipping towards SW and trending NW-SE. The lithology of the host rocks has strong control on the disseminated mineralisation throughout the deposit. Two domains of rock formations are clearly distinguished at Seguelen: Fatoya Formation(Ffm) domain ; and Kintinian Formation (Kfm) domain. The two domains are separated by a contact zone of 1.7 m wide parallel to bedding and characterised by the presence of quartz fragments as well as thinly sheeted shale and black shale. This contact zone is identified as disconformity. The major tectonic deformation which has affected the region is known as D2 corresponding to the Eburnean orogeny. The major D2 related structures is the regional thrust striking N-S over an area of 12 km long and 3 km wide and within which corridors all Siguiri gold Mine open pits are located. In the N-S trending structures, there is east-northeast shortening and north-northwest extension. There is pervasive hydrothermal alteration (carbonatization and sideritization) and supergene alteration in the all pits. The hydrothermal alteration attests the intensity of hydrothermal fluid-flow over the host rocks. The hydrothermal fluids flowed along the fractures and within the wall rocks through bedding plans to form numerous auriferous quartz veins bearing disseminated sulphides through chemical reaction between fluids and wall rocks, which are remarkable at Seguelen pit. Three quartz vein sets are distinguished at Seguelen: NNE-SSW quartz vein set NE-SW quartz vein set NW-SE quartz vein set The NE-SW and NNE-SSW quartz veins are often lenticular and associated with the bulk mineralisation.

- Description: Feedbacks between abiotic variables and community structure in Antarctica are poorly understood. Research is, therefore, required to elucidate the patterns of biodiversity that exist and the factors that influence them, particularly under changing climates. Landscape processes affect environmental heterogeneity, which in turn affect patterns of biodiversity. Two inland Antarctic nunataks, Robertskollen and the Northern Buttress of Vesleskarvet, were selected for investigation to determine the potential impact of selected environmental factors on lichen distribution and abundance, at the intra- and inter-nunatak scales. Lichens were found to prefer rock faces with dips between 1° and 45°, and northern/southern aspects. Lichen colonisation was mostly in microtopographical features that result from rock weathering. The distribution of lichens was found to be regular at the intra- and inter-nunatak scale, whereas lichen abundance was found to be mostly influenced by temperature. On the Northern Buttress, rock hardness displays a similar pattern to lichen abundance, both of which are suggested to be a function of exposure time, which is dependent on deglaciation. The two nunataks serve as excellent laboratories that can potentially be used as proxies for investigating the possible impacts of climate change

- Description: Amartya Sen argued that poverty was the “deprivation” of the capability to lead a “good life”, therefore ending poverty meant meeting basic physical and social needs, and enabling meaningful economic and political choices. The principal objective of this research was to investigate whether (and if so, in what ways) post-apartheid state-provided non-contributory cash social grants in South Africa reduced “poverty” in Sen’s sense. This thesis used Ezibeleni, a historically black working class township at Queenstown, in the Eastern Cape, as a reference area. Using in-depth interviews, it found that social grants did help reduce poverty, both in terms of helping meet basic needs and enabling grant recipients to make more choices, including facilitating job searches and small businesses. However, it was also found that grants fall short of ending poverty, as the grants were too small to adequately cover basic needs in the context of large family sizes, a serious and long-term lack of resources, persistent unemployment, and high indebtedness, and could also enable only a limited expansion of choices. The grants played a positive role, but were inadequate to remove the “unfreedoms” facing the poor.

- Description: My study explores the politics of viewing and the gaze. I argue that the gaze both arrests and objectifies the body, which in turn transforms subjects into objects therefore regulating social behaviour. The basic notion of the gaze will be explored throughout this thesis and thereby contextualizes my sculptures, which are casts of my naked body. My particular concern lies in how the ideas of surveillance have had an influence on architecture and buildings in Grahamstown. Throughout this mini thesis, I will explore a number of architectural spaces of Grahamstown such as the Provost prison, Fort Selwyn and the Camera Obscura which I argue were all designed based on the ideas of surveillance. The entanglement of Grahamstown architecture and the female form as a subject of voyeurism forms an important part of this thesis, as the context of Grahamstown architecture is centered on visibility, which in turn subjects people to a form of discipline. The Provost Prison, the Camera Obscura and the forts of Grahamstown are all good examples of this. Outside of this, the female body is also subjected to the gaze, which in turn suggests that the female body is also under surveillance and as a result also becomes disciplined. My installation is a response to Antony Gormley’s Event Horizon, in which he placed 33 steel and fibreglass casts of his own naked body at an elevated level on buildings around Manhattan and Brazil. In this discussion I have contextualized my work with reference to the ideas of different theorists. The three main theorists I have cited are Michel Foucault, Jonathan Crary and Laura Mulvey. Foucault is specifically cited due to his discussion on Panoptic power, surveillance and docile bodies. Crary makes a number of important points with regards to the ideological operations of the Camera Obscura as well as its history while Laura Mulvey’s writings form the basis of the voyeuristic gaze from the perspective of a feminist.

However, HIV-associated neurocognitive decline still persists in the era of ARVs. Within the framework of brain plasticity, a number of researchers have begun to assess the feasibility of cognitive rehabilitation therapy as a complement to ARVs to reverse neurocognitive decline as a result of HIV (e.g., Becker et al., 2012). Only one study has been conducted in South Africa, by Zondo & Mulder (2014), assessing the efficacy of cognitive rehabilitation in a paediatric sample. The current research builds on the above mentioned study by implementing an experimental approach to examine the effect of cognitive rehabilitation in a sample of both HIV positive and HIV negative children. Five HIV positive and six HIV negative children were assigned to either an experimental or control group. The experimental group underwent two months of cognitive rehabilitation therapy remediating sustained attention, whereas the control group took part in placebo activities. Sustained attention measures were taken before and after the intervention training sessions, using a sustained attention subtest from the Test of Everyday Attention for Children (TEA-CH). A Mann Whitney U Test revealed that the experimental group (Mdn=38.50) did not differ significantly from the control group (Mdn = 37.00) after the cognitive rehabilitation intervention, U=12.00, z= -.55, p= .66, r= -.17. But a Wilcoxon Signed Rank Test found that there was a significant improvement from pretest scores (Mdn=31.00) to posttest scores (Mdn=38.00) following the rehabilitation for HIV positive participants in the sample, T=15.00, z = -2.02, p= .04, r= -.90. This raises the possibility that cognitive rehabilitation could be used as a low cost intervention in underdeveloped contexts

- Description: This thesis used the events of the 2007 financial crisis as a means of being able to add to the research already done on South African unit trusts. The objective was to study the risk-adjusted performance of South African general equity unit trusts against the market during the period between 2005 and 2014. This period took into account the bull market preceding the financial crisis, the market crash of 2007 and the subsequent market recovery that followed. Data was obtained online through the I-Net BFA data base and included 161 general equity unit trusts that contained a full data set. In addition to the general equity unit trusts, the Satrix40 was studied to compare a passive unit trust against those that are actively managed. The 10 year Government bond was also used as a risk-free rate to add to the comparisons of performance results. The Sharpe, Treynor and Jensen measures were applied to the data with the results adding more support to the opinions that markets are fairly efficient and active investment strategies are being challenged by consistently well performing passive investments. Throughout the duration of the study, taking into account the varying economic cycles, the Satrix40 passive investment showed the best average overall return on simple return calculations as well as during the risk-adjusted measurements. In support of active investment management, unit trusts showed their best relative performance figures during the period of the financial crisis. This suggested that active financial managers were able to make the active calls necessary to weather the storm of the financial crisis. While the study did have its limitations, the results it produced are intended to offer investors further knowledge in enabling them to make more educated investment decisions in the future.

- Description: South African history is rooted in racial identities, inequalities and injustices, which the post-apartheid government has sought to address for twenty years since 1994. The transition to a post-apartheid society though has been a difficult one with the social structure and everyday life still marked by the racial past. Though racial classifications on an official basis no longer exist, racial identities continue to pervade the country. Of particular significance to this thesis are black identities including the possibility of black inferiority, which I examine in relation to black post-graduate university students in contemporary South Africa, specifically at Rhodes University. In examining this topic, I draw extensively on the work of Frantz Fanon, who wrote about both colonial society and the emerging post-colonial experience. Fanon was a young black intellectual whose work was in part based on his own experiences of being a once-colonised black person in a world which he perceived as being dominated by whiteness. In his work he expresses his own perceptions of whiteness and how the black identity has come to be shaped by and around this dominant white foundation. Fanon extensively discussed the lives of black intellectuals and elites, and demonstrated how the black identity becomes shaped by and around the world of whiteness. In doing so, he raised a range of themes, such as black inferiority, mimicry and double consciousness. I draw upon the work of Fanon in a critically sympathetic manner to delve into the experiences of black postgraduate students as they negotiate their way through a university setting dominated by a white institutional culture. I bring to the fore the argument that the racial identities of these students is not fixed and sutured but, rather, is marked by considerable fluidity and ambiguity such that black identity must be understood not just as a state of being but also as a process of becoming.

- Description: Teachers’ perceptions are that currently dissemination in schools is ineffective and must change. The tensions that surround the dissemination of the reports are late arrival of Examiners’ reports which clash with preparation of learners for the first term examinations. Furthermore, the time the Examiners’ reports get into teachers’ hands are late and thus result in teachers rushing through it to incorporate the recommendations given in it in the second term or in some instances teachers do not attend to it at all. The number of copies of the Examiners’ reports provided to schools appears to be inadequate. HODs still having to duplicate reports before disseminating them add to their work load and further delay dissemination of the reports to individual subject teachers. Although the teaching and learning approach in Namibian classrooms should be based on LCE, dissemination of the actual physical reports are currently restricted to teachers only with them only verbally communicating feedback given in the reports to their learners. Support in dissemination of Examiners’ reports from peers and superiors in the majority of the schools appear to be lacking. Changes would like to be seen in the timing the Examiners’ reports are available at schools, the number of hard copies provided to schools and exploring and embarking on alternative ways of disseminating the reports. The percentage of utilization of the Examiners’ reports is relatively high, yet still not the optimum. A reasonable number of Namibian learners are disadvantaged and not exposed to a source of information that can make their Biology learning more efficient because some of their teachers are not using Examiners’ reports in their teaching. The main reason for non-utilization of the reports by Biology teachers is a result of inefficient dissemination at individual schools. The argument being that if the reports are not given to the teachers they and especially novice teachers will not know about the existence of this useful teaching and learning resource. Examiners’ reports are an important and systematic impartial source of high quality data on learning in the Namibian education system. Therefore, effective dissemination and utilization of the reports must be advocated and strengthened. DNEA and the Khomas regional office should embark on tapping into available development in information technology by doing research into the possibility of disseminating the Examiners’ reports electronically. A pilot in this regard should be conducted in the Khomas region as a measure to ensure dissemination can become more efficient in the future. To ensure that teachers optimally utilize the Examiners’ reports, they should be provided to schools when the school first term commences. The Khomas regional office should strengthen their involvement in utilization by arranging annual workshops where the content of the reports can be discussed to ensure that the feedback given in the reports can aid in developing and strengthening Biology teachers’ subject content knowledge as well as pedagogical content knowledge. Optimal utilization of Examiners’ reports can enable mediation in learners which can ensure effective learning and mastery of Biology by learners which can ultimately lead to an improvement in pass rate in Biology. Therefore, appropriate support to aid teachers’ professional development can enhance maximum utilization. Furthermore, an area for future research could be to give the Examiners’ reports to learners to determine the impact it has on their learning.

Challenges of post-apartheid state-owned company pension fund reform: a case study of the controversy around the Transnet-Transport Pension Fund

- Description: This thesis examines the restructuring of the pension funds of Transnet, a South African state-owned company involved in transportation, from the 1990s. Two of its main pension funds, the Transport-Transnet Pension sub-Fund (TTPF) and the Transnet Second Defined Benefit Fund (TSDBF), have been surrounded by controversy, with major court actions brought by aggrieved pensioners in 2006-2012 and again from 2013, and smaller cases in 1997-1999 and 2004. (There were also a number of smaller cases, mostly unsuccessful, but the thesis will not examine them). The case that started in 2013 is the biggest class action in the country‟s history, and makes claims of serious mismanagement and bad faith against the Transnet management. But the fundamental grievance is that (according to the 2013 legal case) “more than 80% of pensioners earn less than R4 000.00 a month… 62 % earn less than R2 500.00… 45% of the pensioners earn less than the state‟s ordinary old-age pension” grant for the poor. Although that case is ongoing, this thesis examines the background and controversies that frame the case. It provides an overview of the history and development of the South African pensions system and South African state-owned companies; it examines how these have been shaped by the apartheid and post-apartheid periods, and by the rise of neo-liberalism; it examines the evolution of Transnet and its pensions systems, from the early days of the South African Railways and Harbours Administration (SAR&H, formed 1910), to its restructuring into the South African Transport Services (SATS) in 1982, and then into Transnet in 1990. The thesis shows that the operations of the TTPF and TSDBF, which are closed to new members, have had serious effects on pensioners that rely upon them. Pensions are very low (the main reason for the various court cases), and this is for a range of reasons. Annual increases in pensions are formally set at below-inflation levels, leading to falling real incomes. More pressure on pensioners‟ livelihoods has arisen from Transnet‟s cuts to other benefits, like the medical aid Transmed, provided to pensioners. While the schemes are solvent, the pensions generally started at a low base, partly because most pensioners were relatively poorly paid workers before retirement (and the pensions were linked to former salaries). There is also a racial dimension: while most white workers at SAR&H/ SATS and Transnet were poorly paid, black, Coloured and Indian workers were paid even worse, and, further, were only brought into the pension schemes late. Both TTPF and TSDBF are defined benefit funds, which means members are guaranteed specific benefits at retirement, with the employer obligated to inject funds to meet shortfalls where needed. Yet neither the state nor Transnet has been willing to take actions to lift the basic pensions, such as investments into the funds, or to make systematic ex gratia payments to bring the pensions to a reasonable level, to remove historic racial inequalities between pensioners, to increase medical aid co-payments or coverage or to otherwise address the pensioners‟ situation. It does not seem that the reason for the problems is that the two funds have been severely mismanaged or asset-stripped, as alleged in the 2013 class action: it must be noted that both funds report surpluses. But the surpluses are possible because the pensions are low and falling in real terms, and the numbers of pensioners declining due to deaths. It seems clear that Transnet is unable or unwilling to act to decisively improve the situation of the pensioners: ensuring a surplus on existing pension funds is a major goal. This is partly because Transnet itself has ongoing financial problems, and partly because it operates in the context of neo-liberal restructuring, like corporatisation, commercialisation and privatisation, which places limits on the additional funding of the funds. At the same time, the pensioners have very little real, as opposed to a nominal, say in the administration of the pension schemes, limiting their ability to affect the rules and administration or raise issues. The thesis seeks to use historical institutionalism, which sees policies and major institutions, including state-owned companies, as shaped by power and conflict, especially between classes. This is used to try and explain changing state policies and the changing role and actions of state-owned companies, as a way of understanding Transnet‟s actions, as well as its treatment of its pensioners.
