- Description: The continued growth of world commerce has led to the advance of the permanent establishment principles. These principles are, however, constantly challenged by the developments of e-commerce. This thesis considers the taxing of a permanent establishment and the influence of e-commerce on the concept of a permanent establishment. In 2000, the Organisation for Economic Co-operation and Development (“OECD”) developed and introduced guidelines on how to deal with e-commerce in the context of a permanent establishment. Since the OECD guidelines on e-commerce were issued, the permanent establishment principles have come under further scrutiny. The latest development came about in 2013 with the release of the Base Erosion and Profit Shifting (“BEPS”) Action Plan. This Action Plan addresses the intention of the OECD to deal with the taxing of the digital economy. With the development of e-commerce and the result of e-commerce creating intangible boundaries between countries, the concept of a virtual permanent establishment has emerged. This has resulted in the need to tax a presence of an enterprise in a jurisdiction where no actual physical connection can be established. Various authors have made suggestions on how to ensure that an economy in which business is being carried on is correctly compensated for in the form of taxes. The source of income is the driving force for the imposition of taxation today. The main goal of this thesis was to explore the alignment of the concepts of a permanent establishment and e-commerce in the digital economy. This study therefore examined the concepts of both permanent establishments and e-commerce, and explored authors’ views and suggestions on how to deal with the inter-related effects of these two concepts. The relevant Action Points in the OECD Action Plan were also considered. , Maiden name: Venter, Michelle

- Description: A key incentive for accounting research is to provide evidence on the usefulness of earnings in making economic decisions. Of particular interest over the last two decades is the issue of the quality of financial reporting, specifically the quality of earnings, given the number of global financial scandals reported during that period. The quality of earnings is driven by the choices, estimates and judgments that the accounting standards make available to managers in order to portray the firm’s economic position and performance in a timely and credible manner. However, this leeway in financial reporting also creates opportunities for earnings management. The objective of this thesis is firstly to establish whether earnings manipulation has had the ability to predict cross-sectional returns in South Africa during the 2007-2014 period. In other words, the purpose of this thesis is to find evidence whether the market reacts to earnings management practices, as measured by accruals, and rewards high earnings quality companies with higher equity returns (a process known as the accrual anomaly). The timeframe selected for the research encompasses the global financial crisis, a period in which accounting manipulation incentives are likely to be strong. Secondly, this study attempts to establish the presence of the accrual anomaly amongst growth and value firms. The motivations for earnings management of the former are expected to be strong. Securities are allocated to portfolios according to accruals and the subsequent equity returns are analysed cross-sectionally to establish the existence of the accrual anomaly and hence assessing the usefulness of earnings manipulation in predicting equity returns. To provide evidence for the presence of the accrual anomaly amongst growth and value shares, securities are independently allocated to portfolios according to their book-to-market ratio and accruals and a cross-sectional analysis is performed on their subsequent equity returns. In order to increase the robustness of the tests, two measures of accruals are used: a balance sheet approach and a cash flow measure. Evidence is provided for the presence of the accrual anomaly among South African listed companies for the balance sheet measure of accruals but not the cash flow approach. Whilst the accrual anomaly is significantly present in a growth-neutral-value construct, statistical significance is not established when growth and value shares are considered individually.

- Description: Decision makers have long relied on experts to inform their decision making. Expert judgment analysis is a way to elicit and combine the opinions of a group of experts to facilitate decision making. The use of expert judgment is most appropriate when there is a lack of data for obtaining reasonable statistical results. The experts are asked for advice by one or more decision makers who face a specific real decision problem. The decision makers are outside the group of experts and are jointly responsible and accountable for the decision and committed to finding solutions that everyone can live with. The emphasis is on the decision makers learning from the experts. The focus of this thesis is an overview and comparison of the various elicitation and combination methods available. These include the traditional committee method, the Delphi method, the paired comparisons method, the negative exponential model, Cooke’s classical model, the histogram technique, using the Dirichlet distribution in the case of a set of uncertain proportions which must sum to one, and the employment of overfitting. The supra Bayes approach, the determination of weights for the experts, and combining the opinions of experts where each opinion is associated with a confidence level that represents the expert’s conviction of his own judgment are also considered.

- Description: Many South Africans may not have adequate retirement savings when they retire and this has the effect of a low income replacement ratio on retirement that may lead to a decrease in the standard of living of the retiree and in extreme cases the retiree becoming dependent on their family and the government. Owing to this trend of no or inadequate retirement savings, South Africa embarked on a retirement reform journey in 2004. The goal of this research is to determine whether the retirement reform mechanisms outlined by National Treasury would encourage individual retirement savings that should assist South Africans to achieve stability of income in their retirement. This research analysed the current retirement savings options and vehicles available for South Africans, the current tax incentives and disincentives and reviewed the proposed changes to tax incentives and disincentives during the accumulation phase of retirement savings and explained how these proposed tax incentives are harmonised for the accumulation phase of retirement. The research explained how National Treasury aims to limit pre-retirement withdrawals and how it intends to encourage the annuitisation of post-retirement benefits. The penultimate chapter of this research measured the effect (by making certain assumptions) of the changes proposed by National Treasury on the income replacement ratio of the retiree. Throughout the research comparisons were made between The OECD Roadmap for the good design of defined contribution pension plans and National Treasury’s proposals. This research did not directly address the effect of increased life expectancies on retirement savings or increases in youth unemployment and the effect that this may have on retirement savings. The effect of financial charges levied on retirement savings on the income replacement ratio of a retiree was also not explored. Furthermore, not all pension funds are regulated by the Pension Funds Act and how these pension funds can be brought within the purview of the Pension Funds Act was not investigated. Automatic enrolment of retirement savings for all employees in South Africa in retirement vehicles is a further research area that could be addressed.

- Description: This study focuses on two roll-outs of a, year-long National Qualification Framework (NQF) level 5, environmental education learnership in South Africa and attempts at enhancing collaborative learning at workplaces using a familiar social networking site called Facebook. This study uses the Facebook group sites created for the workplace course component of the course as one of the means of data collection. Additional interviews and focus groups with learners and administrators on both Environmental Education Training and Development Practices (EETDP) courses also informed the study. The study is located within the context of the rise of the information age, its effects on socio-ecological landscape at large and ways of using social networking sites in order to facilitate scaffolding and meaning making within zones of proximal development for environmental education learnerships. It also looks at the model of apprenticeship and workplace based learning as it is broadly located at the nexus of the SAQA-led academic inquiry into workplace based learning and professional development. It was found that the use of Facebook on the EETDP learnership allowed for collaborative learning to take place between peer to peer interactions as well as between tutors and learners. It was also noted that scaffolding processes requires both technical assistance and strong instructional input from course tutors. One of the most important findings in terms of collaborative learning and engaging within the Zone of Proximal Development (ZPD) was that learners were able to communicate more effectively and freely with both fellow learners and tutors on course after participating on the Facebook group sites. The study offers recommendations on how a social networking platform like Facebook can be utilised effectively for environmental education. The study recommends that scaffolding of workplace based tasks and concepts needs to be better integrated with the course and in both online and offline interactions between learners. It also illustrates how social networking sites can become powerful tools for creating meaning making when combined with course work.

This research study reports on pertinent findings from a study which set out to determine Rhodes university undergraduate students‟ entrepreneurial intentions and their pull and push factors that have brought them to the decision to become entrepreneurs. A survey, using a 43 question structured web-based instrument was used to capture the responses from undergraduate students across different departments at Rhodes University, Grahamstown. Key findings suggest that few undergraduate students intend to enter into an entrepreneurship career immediately after completion of their studies, whereas many of the respondents were more interested in doing so five years after graduation. The vast majority of students were satisfied without having formal entrepreneurial education and factors such as previous employment in entrepreneurial activities, and family influence had a statistical significant relationship with entrepreneurial intention.

- Description: The endangered Western Leopard Toad (Amietophrynus pantherinus) is endemic to the winter-rainfall parts of the Western Cape, areas which are also favoured for human settlement. Residents in the Noordhoek area witnessed many toads being killed on roads during their annual migration to breeding ponds. Concerned citizens mobilised a volunteer group to mitigate this threat to the species. Toad NUTS (Noordhoek Unpaid Toad Savers), a well-established and successful citizen science group is explored as a case study of how environmental citizenship emerges in a citizen science group. This research has three research goals. Firstly to probe the enabling and constraining factors shaping the Toad NUTS practices, secondly to investigate the learning dynamics in the citizen science group and thirdly to understand how participation in citizen science develops environmental citizenship. Practice architectures theory (Kemmis & Grootenboer, 2008) was used to explore how cultural-discursive, economic-material and social-political arrangements shape the practices of the Toad NUTS group. The Toad NUTS group was identified as a community of practice, therefore Lave and Wenger’s (1991) communities of practice theory was used to better understand the social learning processes within the group. The Global Citizenship Education international policy document was used to capture the aims of citizenship education as it relates to environmental issues and identifies the competencies that citizenship education initiatives should develop. The practices of the Toad NUTS group were investigated for evidence of the goals and competencies identified in the Global Citizenship Education policy documents of environmental citizenship. Data was generated through documentary research, surveys, a questionnaire, semi-structured interviews and observations. The data was stored, organised and analysed using NVivo data management software in three phases corresponding to the three research goals. With respect to Goal 1, the evidence suggested that there are various shaping arrangements of cultural-discursive, material-economic and social-political configurations which influence Toad NUTS practices. Volunteers must learn to navigate these arrangements in order to successfully implement conservation strategies. The shaping features identified were the WhatsApp group communication system used by volunteers; public awareness and education strategies; equipment, material and funding required for implementing the group’s practices; power balances and exchanges between stakeholders in the conservation field; bureaucratic processes and scientist-lay person exchanges. Very important for facilitating social-political connections to various stakeholders, is the membership Toad NUTS enjoys on the Western Leopard Toad Conservation Committee. With respect to Goal 2, four interconnected components of learning were investigated. These were: learning as belonging, learning as doing, learning as meaning-making experience and learning as becoming. Members learn by doing things together like training, patrolling and deliberating problems in the field. They learn by exploring what is collectively known from past and unfolding experiences. Evidence showed that learning deepens as Toad NUTS members perceive their praxis as meaningful and their identities evolve as their knowledge and experience grows. This strengthens members’ sense of belonging and identification with the Toad NUTS group. In time the group develops a reputation and the wider community acknowledges the expertise and knowledge that resides with the group. With respect to Goal 3, it was found that volunteers who have a predisposition for environmental citizenship are more likely to join a citizen science group. Although volunteers care about nature and want to make a difference, it is after gaining access to the embedded knowledge and knowledge processes of the citizen science group that they realise meaningful sustainable solutions to the issue(s) that the project is concerned with. It was found that knowledge paired with reasoned practice enables the agency of volunteers to bring about positive and meaningful change in the local environment. If facilitated carefully, citizen science can make positive contributions to the field, in this instance, conservation, while allowing volunteers to exercise environmental citizenship engaging in participative governance with regard to the project.

- Description: High failure rates in English as a second language at secondary school level have become a concern in the Namibian education sector. From 2005 until 2013, the overall performance of the grade 12 learners in English as a second language on Ordinary level in the Oshana region was unsatisfactory. In fact, only a minority (18.52 percent) of the grade 12 learners obtained a grading in the range of A to D in comparison to the majority (81.48 percent) of learners who obtained a grading of E to U. The poor performance was attributed to: poor sentence structure, syllabification and spelling (Directorate of National Examination and Assessment, 2007-2010). The causes of these low performance rates however, were not scientifically explored in this region. Therefore this study embarked on an investigation in order to identify the reasons behind the low performance rates of the grade 12 Oshiwambo speaking learners of English and to determine whether the impressionistic results from the Directorate’s report correlate with the present study’s findings. In order to understand the dynamic linguistic system of the learners, a contrastive analysis of Oshiwambo and English was done in order to investigate the potential origins of some of the errors. An error analysis approach was also used to identify, classify and interpret the non-standard forms produced by the learners in their written work. Based on the results obtained from this study, a more comprehensible assessment rubric was devised to help identify learners’ written errors. A group of 100 learners from five different schools in the Oshana region was asked to write an essay of 150 to 200 words in English. The essays were analysed using Corder’s (1967) conceptual framework which outlines the steps that a researcher uses when undertaking an error analysis study. The errors were categorised according to Keshavarz’s (2006) linguistic error taxonomy. Based on this taxonomy, the results revealed that learners largely made errors in the following categories: phonology/orthography, morpho-syntax, lexico-semantics, discourse and techniquepunctuation. The study concluded that these errors were most likely due to: first language interference, overgeneralisation, ignorance of rule restriction and carelessness. Other proposed probable causes were context of learning and lack of knowledge of English grammar. The study makes a significant contribution, in that the findings can be used as a guide for the Namibian Ministry of Education in improving the status quo at schools and informing the line Ministry on various methods of dealing with language difficulties faced by learners. The findings can also empower teachers to help learners with difficulties in English language learning, thereby enabling learners to improve their English language proficiency. The study has proposed methods of intervention in order to facilitate the teaching of English as a second language in the Oshana region. In addition, the study has devised an easily applied assessment rubric that will assist in identifying non-standard forms of language used by learners. The reason for designing a new rubric is because the rubric which is currently being used is believed to be subjective, inconsistent and lacks transparency. , Name in Graduation Programme as: Nghikembua, Anneli Ndapanda

- Description: High failure rates in English as a second language at secondary school level have become a concern in the Namibian education sector. From 2005 until 2013, the overall performance of the grade 12 learners in English as a second language on Ordinary level in the Oshana region was unsatisfactory. In fact, only a minority (18.52 percent) of the grade 12 learners obtained a grading in the range of A to D in comparison to the majority (81.48 percent) of learners who obtained a grading of E to U. The poor performance was attributed to: poor sentence structure, syllabification and spelling (Directorate of National Examination and Assessment, 2007-2010). The causes of these low performance rates however, were not scientifically explored in this region. Therefore this study embarked on an investigation in order to identify the reasons behind the low performance rates of the grade 12 Oshiwambo speaking learners of English and to determine whether the impressionistic results from the Directorate’s report correlate with the present study’s findings. In order to understand the dynamic linguistic system of the learners, a contrastive analysis of Oshiwambo and English was done in order to investigate the potential origins of some of the errors. An error analysis approach was also used to identify, classify and interpret the non-standard forms produced by the learners in their written work.

Evaluating coverage of the environment: a comparative study of the observations of academics and journalists

- Description: This study is a comparative analysis of the way that academics and journalists evaluate media coverage of news about the environment. The purpose is to gain insight into the kind of contributions that each of these groups can make to debates about the role that such coverage should play within processes of public deliberations about the environment. The dissertation begins by establishing theoretical terms of reference for assessing discussions of the journalistic coverage of the environment. It proposes that it is of value to consider the conceptualisation, within such discussions, of credible knowledge about the environment and, more particularly, to establish whether such conceptualisation is based within a positivist, interpretive, or critical realist paradigm. It is demonstrated that each of these epistemological traditions brings valuable perspectives to the discussion of journalism about the environment within such literature. It is, however, the positivist perspective that remains dominant, and this limits the extent to which the potential of the other two epistemological positions are fully realized. It is also demonstrated that there is a tendency, within this literature, to focus on the performance of individual journalists with minimal attention to the particularities of institutional and social context. It is proposed that this tendency results from the adherence to a positivist approach to the evaluation of journalism. The dissertation then describes the design and implementation of the empirical component of the study - dealing with decisions made about the overall methodological framing, the choice of method, the fieldwork plan and the approach to analysis. It is explained that the aim of the empirical component was to examine South African print journalists’ discussions of coverage of the environment in their own publications, and to compare such discussion to that which is represented in the academic literature. The dissertation then presents a summary of the themes that emerged from the analysis of the interview material that formed part of this empirical work. It is demonstrated that the evaluation of coverage of the environment, as articulated by the research participants, is informed by many of the assumptions and values that can be identified within academic literature. Such evaluation is, furthermore, similarly informed by a positivist, interpretive and critical treatment of knowledge - with, again, a tendency for the positivist position to dominate. One important difference is that the research participants include more references to institutional context. It is proposed, however, that the tendency to prioritise a positivist epistemological framing continues to place limitations on the extent to which the participants are able to fully articulate their knowledge about such context.

- Description: The neo-liberal restructuring of state assets and facilities, which has taken place internationally over the past three decades, as well as in South Africa, has been a matter of great controversy. Privatisation, in particular, has been a polarising issue, especially when applied to fields like healthcare. Supporters of privatisation view it as cutting costs, mobilising funding, expertise and innovation, resulting in improved delivery, and opening possibilities for a spread of ownership. Critics claim the process involves retrenchments, declining services for the (poorer) majority of people, and a focus on the elites as citizens become transformed into customers, and with any economic empowerment going to the already prosperous. This thesis examines these issues by looking at the privatisation of hospitals in South Africa, with a case study of the Netcare-Settlers Public Private Partnership (PPP) (also known as the Settlers Private Hospital) in Grahamstown, South Africa. Netcare is South Africa’s largest private hospital company, and also has substantial operations in the United Kingdom. The thesis sets out the context: a highly inequitable healthcare system in the country, the rise of privatisation in the apartheid and post-apartheid eras, and healthcare privatisation. In terms of the Netcare-Settlers PPP, the thesis examines how the PPP was structured and developed, focusing on the impact of the PPP on non-clinical operations. The thesis argues that the results of the PPP are mixed, that it has greatly improved areas like facilities, maintenance, cleaning and catering, performed less well in increasing the doctor/ patient ratio or in attracting specialists, and is associated with the widespread and problematic use of outsourcing of service workers like cleaners and security. Overall, the PPP has improved healthcare, with some effective sharing of resources between the public and private parts of the hospital, but also relies on a pool of relatively low waged, under-unionised, labour. In terms of the general debate over privatisation, the Netcare-Settlers PPP shows that both supporters and critics have some valid points, and that privatisation in practice is not an either/ or, black/ white, good/ bad proposition, but something more complex. The success and failure of PPPs depend on the details of the contracts, and these can be used to maximise the performance of both the public and private partners. Better contracts may help avoid the uneven results seen at institutions like the Netcare-Settlers PPP.

- Description: This is a qualitative study which focuses on how Liberty Life Swaziland distributes microinsurance to the bottom of the pyramid within Swaziland. Using stratified purposive sampling, this study identified 5 managers within Liberty Life and 4 managers from brokerages and affinity partners who had a minimum of 3 years’ experience in distribution of microinsurance. Semi-structured and in-depth interviews were conducted by the researcher with these managers. Interviews were stopped when there was data saturation. To induce emerging themes from the data, open-coding and constant comparison technique was used. Findings in this study reveal that to distribute microinsurance to low income households, Liberty Life objectives are to; (1) provide relevant solutions in a cost effective manner, thus keeping premiums as affordable as possible, (2) provide simple products which are easy to understand by customers, (3) make services accessible, and (4) make doing business easy. In this regard, Liberty Life distribution strategy is to partner with bulk retailing entities that have a client base they already service and benefit from nationwide presence and infrastructure. Lastly, the perspectives of both internal and external stakeholders in microinsurance are discussed to evaluate the challenges and successes experienced in implementing the distribution strategy. This study is valuable to critically understand the current distribution strategy from the viewpoint of key intermediaries, but also pinpoint how efforts to achieve microinsurance distribution objectives can be enhanced. Lastly, the study recommends that; a selection criteria be set for distribution partners, partnership with mobile network operators, investment in continuous training of distribution partners and knowledge sharing between Liberty and intermediaries to cease the opportunity at the bottom of the pyramid.

- Description: The focus of this study is on the experiences of a small sample of local women who have been recently diagnosed with HIV. The aim of the research was to give these women an opportunity to express their first-hand, personal accounts of living with HIV. Five isiXhosa-speaking women were recruited and interviewed. These accounts were collected and analysed within in the methodological framework of Interpretative Phenomenological Analysis, a qualitative approach that is becoming increasingly popular in the broad fields of health and clinical psychology. Data was analysed for meaningful units, which were interpreted inductively and hermeneutically, and categorised into super-ordinate themes. Five themes within the participants’ experiences of living with HIV were identified: (1) experiences of diagnosis, (2) experiences of stigma, (3) social support, (4) coping strategies, and (5) HIV as one of many assaults to self. Implicated in these experiences are the ways in which these women have appraised themselves and their situation after an HIV-positive diagnosis, appraisals that are shaped by HIV-related stigma. A variety of negative emotional reactions are common following the diagnosis, often compounded by the direct experiences of HIV-related stigma. Women in the study adopted different kinds of coping strategies based on the resources and social support available to them. Also significant is that for these women who had typically endured a variety of traumatic life events, a positive diagnosis was simply one of many life challenges

- Description: The thesis is inspired by recent interests in oxide zinc ores caused by new developments in the technology of hydrometallurgy. The improved techniques turned the non-sulphide zinc ores in to attractive exploration targets due to a number of advantages such as low metal recovery costs and favorable environmental aspects such as the obvious absence of sulfur (Large, 2001). Historically extraction of zinc metal from oxide ores was not possible until recently. The metallurgical complexity resulted in a lack of interest and hence some economic oxide zinc ores might have been missed by conventional exploration techniques. The study presents a review of exploration status at Skorpion mine based on different exploration techniques and their application to sulphide and oxide zinc ore exploration. The challenge facing the mineral exploration industry today is the inability to detect mineral deposits under cover. Therefore a key to successful exploration program lies in the selection of the right exploration technique. Important parameters that should be highlighted in the exploration methodology are the geological situation of an area, equipment applicability and effectiveness, survey limitation, equipment mobilization and the safety aspects involved. The aim of this thesis is to provide a general guideline for sulphide and non-sulphide zinc ore exploration on the Skorpion area and other similar geological environments. Geochemical surveys appears to be more complimentary in exploration of non-sulphide zinc exploration. Although geochemical techniques are preferred, it is equally important to choose the right soil horizon. Furthermore, sample media may mean the difference between success and failure in geochemical exploration of non-sulphide zinc mineralization, due to high mobility of zinc in the surficial environment. On cost comparison, surface geochemical surveys programs are more cost effective except for litho-geochemical sampling which are commonly carried out through subsurface drilling. Geophysical techniques have limited application in exploration of non-sulphide zinc mineralization due to a lack of major physical properties (e.g., magnetic and electrical properties) in non-sulphides unlike their sulphide counterparts. However geophysical methods are commendable in delineating massive and disseminated sulphides mainly if they are associated with major Fe minerals (pyrrhotite or magnetite). In addition, geophysical techniques may be effective in mapping of subsurface primary and secondary structures such as basin faults which might have acted as pathways for metal-rich fluids. Terms non-sulphide and oxide zinc mineralization are used interchangeably throughout the thesis. Recommendations on regional and local target generation are presented in the thesis to give some basic guide lines on target generation strategies. The most important conclusion reached in this study is that, success in exploration for non-sulphide or sulphide zinc mineralization might be enhanced through the integrated exploration methodology.

Exploring Grade 12 biology teachers' perceptions and experiences of the dissemination and utilization of Examiners' reports in the Khomas region of Namibia: a case study

- 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.

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.

- Description: ICTs have had a tremendous impact on our educational environment. There have been a huge number of developments and support in implementation of ICT in Higher Education teaching and learning, also referred to as e-learning. Similarly there appears to be quite a number of research conducted on the use of ICTs in blended learning settings worldwide and as well as in South Africa. Very little research however, has focussed on the experiences of lecturers with e-learning, specifically as it relates to Learning Management Systems (LMS). In trying to meet the requirements of its academic programmes and be in line with new developments worldwide, the University which is the focus of this study pilot projected the use of an LMS in a blended learning approach which integrates face-to-face classes with Blackboard, an ICT-based system or tool. Following the implementation of the pilot project, this study explores the experiences of lecturers in their blended learning environments at this university in the Eastern Cape province of South Africa. The research design was that of an interpretative paradigm within a qualitative research approach in a case study methodology. Purposive sampling of six lecturers from departments within faculties across two campuses was done. The data was gathered through interviews, a follow-up questionnaire and document analysis was employed. Using Critical and Social Realism as meta-theories the study employed aspects of Activity Theory as substantive theory to understand particular experiences of blended learning environments and identify conditions which enable and constrain engagement in these environments so as to explore potential lessons to inform the kind of educational support which could be offered to facilitate uptake of the LMS.

- Description: In the past two decades, a considerable amount of research has been carried out on the phenomenon of excessive Internet use, variously termed Internet addiction, Internet dependency and problematic Internet use. Despite this, there is still little agreement as to what constitutes this phenomenon, whether it should be considered a clinical disorder or not and what leads to this excessive or maladaptive use. The terminology used in this study is that of Problematic Internet Use (PIU). Several theoretical models have been proposed in the understanding of PIU including personality models, operant conditioning models, social cognitive and cognitive behavioural models (Davis, 2001; LaRose, lin & Eastin, 2003; Young, 1999). A proposed gap in the literature is the lack of studies exploring participant experiences of problematic Internet use. It is for this reason that this study aimed at exploring the experiences of a small sample of individuals with self-identified problematic Internet use. The implications of this phenomenological data for the above-mentioned theoretical models were then reviewed. This study used an Interpretative Phenomenological Analysis (IPA) approach in exploring these aims. A sample of four participants was selected through purposive sampling techniques. Four major themes emerged from the analysis namely: Escapism, Social Insecurity and Validation, Perfectionism and Control. These experiences of participants were also explored in terms of the conceptual models reviewed in order to compare how closely they related to participant experiences. A strong inter-relationship was found between the four themes mentioned above. The Internet appeared to provide a sense of control and validation to these individuals while simultaneously rendering them unable to maintain control of their Internet usage in relation to this. This sense of control was experienced through an escape from negative emotions, offline obligations and at times a dissatisfactory position in reality. Of the four models reviewed, the Social Cognitive model proposed by LaRose et al. (2003) appeared to offer the most relevant understanding of PIU to participant experiences. The presence of maladaptive cognitions also appeared to feature strongly as an underlying factor in participants' PIU, as theorised by cognitive behavioural models (Davis, 2001; Young, 1999) Finally recommendations are made for further more detailed exploration of PIU using interpretative, experiential methods.

- 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.

The importance of these mental skills is seen in the number of athletes who have formally started training using mental skills training programmes (MST) according to the literature. The study of mental skills in South Africa lags behind other countries like USA, UK and Sweden. This particular study explored the use of mental skills by road running athletes. The study was conducted with six competitive marathon athletes. Semi-structured interviews were conducted as part of an elaborate qualitative methodology design. The data collected from these semi-structured interviews was analysed using thematic analysis. The results show that road running athletes use mental skills that include; mental rehearsal, planning, goal setting and self-talk. The athletes in this research showed the importance of mental skills and it is recommended that formal training in these mental skills will be highly beneficial not only to road running athletes but for all South African sports people in general

- Description: This thesis project examines the work of three female Nigerian authors: Chimamanda Ngozi Adichie, Sefi Atta and Chika Unigwe. They are part of a growing number of young African writers who are receiving international acclaim and challenging narratives that have long defined the continent in pejorative terms. They question what it means to be female and African in a transcultural, global world but counter discourses that are both restrictive and prescriptive. Their female characters are not imaged in binary terms as either victims or villains. For all three writers, the African story has to be told in its entirety incorporating what some may argue are negative stereotypes but doing so in a manner that examines and undermines those same stereotypes. For the purposes of the thesis, I focus on their first novels: Adichie’s Purple Hibiscus, Atta’s Everything Good Will Come and Unigwe’s On Black Sisters’ Street. Chapter One examines Purple Hibiscus and argues that the novel is much more than a coming of age story or, as some critics have posited, an allegory of the postcolonial state. Chapter Two highlights Atta’s use of fairly familiar feminist theories but grounds them in the lived realities of the African city. All three authors are concerned with issues of violence and death. Unigwe’s novel, which forms the focus of Chapter Three, offers a critical perspective on how both of those themes intersect with the increasing commercialisation of global culture. Her characters are female sex workers whose lives are irrevocably altered by the murder of one of their colleagues. I conclude by arguing that the three novels offer a nuanced if not necessarily new understanding of the various social, economic and political forces that continue to shape the lives of women on the continent.

- Description: Modern organisations make substantial investments in Information Technology (IT). Corporate governance practices can no longer ignore the importance of effectively governing IT. Consequently, the third King Report on Corporate Governance (King III) makes specific provision for IT governance, which is implemented through the establishment of an IT governance framework. The purpose of this research is to develop a generic IT governance framework, suitable to any large South African organisation in the public or private sector. The literature considered for this research confirmed the extent of standards and practices available in support of IT governance, together with the roles and structures required to implement them. These included well-known publications such as COBIT, Prince2, ITIL and ISO/IEC27000. Based on the literature review, a theoretical Processes, Enablers and Structures (PES) IT Governance Framework was formulated. The framework was further explored by means of a survey of and structured interview with ten Chief Information Officers (CIOs) of South African organisations with a turnover in excess of R1bn per annum. The final PES IT Governance Framework comprises three dimensions, each of which contains a set of constituent components: • Processes: Strategic Alignment, Value Delivery, Resource Management, Risk Management and Performance Measurement. • Enablers: IT Sub Processes, Supporting Documentation, IT Control Framework, Technology Architecture, Desirable Practice, IT Portfolio Management and Regulation. • Structures: The Board, Office of the CIO, IT Steering Committee, Technology Architecture Forum, IT Programme Management Office and Information Security Organisation. As the number of regulatory requirements and associated compliance pressures grow, the importance of an effective IT governance framework also becomes more prominent. The PES IT Governance Framework offers a uniquely practical approach to addressing IT governance principles that are often regarded as abstract. The final PES IT Governance Framework provides clear guidance on how organisations could implement an IT governance framework, which addresses the strategic alignment of IT to business, value delivery by IT investments, IT risk management, IT resource management and IT performance measurement.
