- 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.

- Description: The optical limiting performance of indium phthalocyanine-based polymer thin-films with large nonlinear absorption coefficients (βeff) and low limiting threshold intensity (Ilim) are described. The absorption cross-sections and the population dynamics of the excited states are also reported. The excited state absorption cross-sections (σexc) are shown to depend on the transition moment between the T1 and T2 states. βeff values have been shown to be related to the population density of the molecules in the T1 state. The improved optical limiting performance recorded for the investigated phthalocyanine complexes in the presence of polymer matrices has been attributed to the aggregation effects of the complexes in the polymer thin-films. The optical properties of the indium phthalocyanine moieties were found to possess robust sensitivity to a change of the polymer materials.

- Description: Zinc phthalocyanine bearing four ascorbic acid units (formed via ester bond between zinc carboxy phenoxy phthalocyanines and ascorbic acid) was synthesized and characterized using different spectroscopic methods. The complex (with or without ascorbic acid) was further adsorbed onto single walled carbon nanotubes (SWCNTs) and further characterized using Raman spectroscopy, X-ray diffractometry, transmission electron microscopy and thermogravimetric analysis. The photophysical properties of the complexes were studied. The synthesized complex showed better photophysical properties when compared to the carboxy phenoxy phthalocyanines alone, this is evident in the increase of the triplet quantum yields (ΦT), triplet life-times (τT) and singlet oxygen quantum yields (ΦΔ). The zinc phthalocyanines bearing ascorbic acid showed improved triplet life-times even in the presence of SWCNTs.

- Description: Novel low symmetry water-soluble zinc phthalocyanines (ZnPcs, complexes 1 and 2) were synthesized and then mixed with silver nanoflowers. Photophysical and photochemical studies were performed in order to determine the efficiency of complexes 1 and 2 as photosensitizers when alone and when combined with the silver nanoflowers. The Pcs show low fluorescence quantum yields and excellent triplet quantum yields of 0.78 (for 1) and 0.66 (for 2) in aqueous media. The triplet quantum yield values increased to 0.80 and 0.89, respectively, in the presence of silver nanoflowers. Long triplet lifetimes ranging from 180 to 200 μs in DMSO were obtained for complexes 1, 2 and their conjugates with silver nanoflowers.

- Description: It is increasingly being recognized that faster socioeconomic develop-ment in Africa is dependent upon the development of Information and Communication Technology (ICT) Infrastructure for the dissemination of data and educational services. The scalability and flexibility provided by Cloud services in terms of resource management, service provisioning and virtualization makes it an attractive system for use with educational and ICT services. The flexibility of pay-as-you-go models combined with the ability to scale computing, storage and/or networking resources makes Cloud computing an ideal candidate for use with education, re-search and scientific infrastructures. Notwithstanding its benefits, transi-tioning from a traditional IT infrastructure to a Cloud computing para-digm raises security concerns with respect to data storage, data trans-mission and user privacy. This paper presents on-going research for the development of Science, Technology and Innovation (STI) infra-structure for the distribution of Information Communication technologies (ICT) services in the African context. The Inter-Cloud Infrastructure Framework (ICIF) proposed, is conceived as a Cloud computing framework suitable for use with National Research and Education Net-works (NRENs) in the SADC region. The ICIF system is used to create an Inter-Cloud infrastructure, and helps NRENs transition from tradi-tional IT infrastructure systems to the Cloud computing paradigm. It also provides new functional/operational components and Cloud services to support the interconnection and/or interoperability among SADC NRENs through the ICIF infrastructure.

- Description: Poor project performance creates a dilemma for managers in both the public and private sectors. Much research has been conducted on project success, but the relationship between organisational architecture and project success has not been fully explored. This led to the main research question of the study, which was: How can project success be better explained and understood from the perspective of organisational architecture theory? A literature review was conducted on the nature of projects, the project environment, and how project success can be defined and measured, including a discussion on success criteria and critical success factors. Organisational architecture was broken down into its core components. These components were further categorised into structural, operational or procedural, and behavioural (culture, motivation and leadership) components after which literature within each of these components were analysed and discussed. The study used a positivistic paradigm and collected quantitative data that was statistically analysed. An electronic questionnaire was successfully launched and distributed via an email link, which worked through the Nelson Mandela Metropolitan University (NMMU) web survey system. This was done within the framework of built environment projects that are typically implemented through partnerships between the public and private sector. A satisfactory response rate was obtained from built environment professionals in South Africa to allow inference of the sample results to the population. The following hypotheses were tested in this study: H1.1: The perception of South African built environment professionals is that there is a significant relationship between organisational structure and project success. H1.2: The perception of South African built environment professionals is that there is a significant relationship between the use and application of traditional operations management tools and techniques and project success. H1.3: The perception of South African built environment professionals is that there is a significant relationship between organisational culture and project success. H1.4: The perception of South African built environment professionals is that there is a significant relationship between motivation and project success. H1.5: The perception of South African built environment professionals is that there is a significant relationship between leadership and project success. An analysis of the survey results revealed that, according to South African built environment professionals, there is an overall significant relationship between organisational architecture and project success. Following an overview of the main findings, an Organisational Architecture – Project Success (OAPS) framework was presented as a recommendation of how to better explain and understand the relationship between organisational architecture and project success.

- Description: The aim of the study is to investigate effective strategies and processes for public participation in the IDP process in the Buffalo City Metropolitan Municipality. A qualitative study was undertaken and literature review on public participation in terms of the Integrated Development Planning was conducted. Relevant secondary data was sourced and structured interviews were conducted with three (3) ward councillors in the Buffalo City Metropolitan Municipal. Focus group interviews were also conducted with ward committee members from three (3) wards in the Buffalo City Metropolitan Municipality. The findings of this research indicate that ward councilors have limited information on administrative processes. This could lead to ward councillors not be able to provide feedback on various service delivery issues and the progress of the municipal projects. Also ward councillors may not be able to influence public participation if they do not understand their role in administrative processes such as monitoring implementation of council decisions and policies. Ward councillors have no influence on the Integrated Development Planning especially the cost and budget estimates for municipal projects which are intended to benefit the members of the community. On the basis of the key findings, recommendations were made that ward committees should be empowered to deal with the complex developments in the Integrated Development Planning process and ward councillors should play a leading role in the Integrated Development Planning process.

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: 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: This thesis intends to contribute to an enhanced understanding of environmental conflicts and their resolution. To accomplish this task the thesis will ascertain the role that value and interests play in environmental conflicts in order to establish an adequate basis upon which they can be resolved. In the process, the thesis will also examine three different approaches, namely, the Standard Approach; the Environmental Impact Assessment (EIA) framework; and the Structured Decision Making (SDM) approach. First, the standard approach is informed by the understanding that focusing on interests instead of human values makes the resolution of conflicts more tractable. In contrast, this thesis argues that an exclusive focus on interests, in the context of environmental conflict resolution, is inadequate in some important respects because there are other factors to be considered such as the environmental impacts at the root of the conflict. Second, the thesis examines the focus on impacts that characterises EIAs. It argues that this approach remedies the limitations of the standard approach insofar as impacts are understood in terms of object value. However, the EIA approach does not provide much guidance on how to deal with conflicting human values. Third, taking into account the fact that the standard approach does not address the question of object value, while the EIA addresses object value but does not deal directly with human values, the thesis examines the SDM approach to environmental risk decisions. The thesis argues that while the SDM approach claims to deal with conflicts involving human values head-on, it does not provide a viable alternative in terms of environmental conflict resolution. This is because it fails to recognise the key distinction between human values and object value despite acknowledging the presence of multiple value dimensions as a major obstacle to value trade-offs and therefore to the resolution of value conflicts. Finally, the thesis recommends an adequate basis upon which environmental conflicts can be resolved.

- Description: Estuaries require sufficient quantity, quality and appropriate timing of freshwater inflow, referred to as environmental flow requirements, to ensure adequate health and functioning. In South Africa the environmental flow requirements of estuaries is determined using Resource Directed Measures (RDM). The present health and importance of an estuary must be considered when determining the ecological flow required to maintain an estuary in its desired state. An Estuarine Health Index that quantifies changes in abiotic and biotic components from natural conditions to present day is used. Health of biotic components is assessed according to changes in species richness, abundance and community composition. There has, however, been debate regarding the calculation of these attributes. In particular, for macrophytes, the inclusion of all habitat within the Estuarine Functional Zone (i.e. 5 m topographical contour) would affect the health and changes over time determined in past assessments. This is due to different areas being included as different areas would be included The aim of this study was to test the validity and suggest improvements to South Africa’s RDM macrophyte health score determination. The health of macrophytes were assessed at varying levels of intensity from desktop studies to thorough field studies. Rapid field studies provided a visual estimate of macrophyte health; while the intermediate and comprehensive assessments quantified change by mapping the distribution of macrophyte habitats from aerial photographs. These approaches were applied to the 64 estuaries within the Mvoti-Mzimkulu Water Management Area (WMA 11), situated in KwaZulu-Natal (KZN) on the subtropical east coast. Historically, these estuaries have supported restricted macrophyte habitats. Consequently, estuaries that presently or historically supported range limited habitats such as mangroves and swamp forest are considered important. Submerged macrophytes are scarce in KZN estuaries due to siltation and low turbidity and thus estuaries supporting this macrophyte habitat are also important. Based on available literature important estuaries were highlighted and selected for field studies. Transects spanning from the estuary water channel to the boundary of the EFZ provided a generalised distribution of KZN vegetation along an elevation gradient. The transition from estuarine to terrestrial vegetation can be used to improve the current EFZ boundaries, as estuarine area has been found to occur outside of the 5 m contour in some estuaries. Results from the desktop assessment indicated that most of the estuaries are moderately modified. There was a 50 % similarity in the macrophyte health scores determined by the desktop assessment to the 2011 National Biodiversity Assessment (NBA). Field studies mostly confirmed the desktop assessment aside from seven estuaries that had different scores. There has been a significant loss of macrophyte habitat with 100% loss of certain habitats from 9 of the 22 estuaries for which there were field assessments. Submerged macrophytes were not found at any of the estuaries that were assessed in the field. Black mangroves, Bruguiera gymnorrhiza (L.) Lam., were rediscovered at Ngane Estuary, however the few individuals could not be considered a ‘mappable’ community (i.e. <0.5 ha). Mtamvuna and Mkomazi estuaries both supported small stands of mangroves that, compared to data from 2006, appeared healthy. Macrophyte habitats and surrounding coastal forest matched the species composition described in the Vegetation Map of South Africa. The freshwater mangrove or Powder puff tree, Barringtonia racemosa (L.) Roxb, was not abundant in the estuaries. It was only found at four (Damba, Fafa, Little Amanzimtoti and Mvoti) of the estuaries that were assessed in the field. Important estuaries, from a botanical perspective, included some of the larger estuaries such as Mgeni, Durban Bay and Sipingo. Smaller, healthier estuaries that presently support mangrove and swamp forest habitat were also identified as important from a botanical perspective. Macrophyte habitats have mainly been lost due to non-flow related pressures. Sugarcane cultivation occurred within the floodplain of 25% of the estuaries. Nutrient enrichment was evident for 12.5% of the estuaries and reed encroachment was evident for 27% of estuaries for which there were field assessments. Development, aside from the N2 road bridges, was evident for 40% of the estuaries assessed in the field. Invasive plant species, including aquatic invasive plants, were present in all estuaries assessed in the field. The extent of invasive plant species was related to the degree of disturbance and surrounding land use pressures. The Mkomazi and Mvoti estuaries that were assessed at a comprehensive level, as they have earmarked for further water abstraction, had the poorest macrophyte health scores. The macrophyte health of these estuaries was much lower than previously determined by the NBA. The decline in health was attributed to the removal of macrophyte habitat for sugarcane cultivation and development as well as displacement by invasive plant species. The areas covered by the macrophyte habitats also differed from the NBA highlighting the importance of updated mapping and ground truthing. Largely differing macrophyte health scores were produced when attributes were calculated using different combinations of macrophyte habitats. Results indicate that only macrophyte habitats and no other floodplain vegetation should be included when calculating abundance. All macrophyte habitats, physical habitats and floodplain should be incorporated when calculating community composition. The minimum of these attributes is used as the overall macrophyte health score as a precautionary approach is followed. Scoring of health is subjective and the only benchmark for determining the most appropriate method is comparion with previous RDM studies. This study illustrates the need for a standardised RDM scoring method that is presented in a manner that ensures the same results irregardless of the speciliast conducting the study. The updated estuary health and importance scores for WMA 11 are necessary to inform management, particularly as few of the estuaries receive formal protection. In conclusion, this study contributed to the limited knowledge of the estuaries of WMA 11 and assisted in determining appropriate methods for assessing the health and importance of estuary macrophytes.

- Description: Businesses have been criticised for their contribution towards the ever-increasing rate of destruction of the natural environment. Although businesses have responded by adapting their management practices, production processes and products, they still face a number of challenges in reducing their environmental impact. One way in which businesses have responded to the environmental crisis is by implementing environmental management systems. Despite the importance of environmental management implementation, researchers have neglected to identify the antecedents that could lead to environmental management system implementation in South African small and medium-sized businesses. Indeed, much of the research on environmental management has concentrated on large business in Europe or the United States. The limited research that has been conducted on environmental management in small and medium-sized businesses has been descriptive in nature, and fails to produce results that are generalisable and that advance the understanding on this topic. Given this situation, the objective of this study was to develop and empirically test a theoretical model to explain the implementation of environmental management systems in small and medium-sized businesses. A quantitative survey methodology was adopted in this study to test the proposed theoretical model empirically. In total, 417 small and medium-sized businesses participated in the survey; 326 of these were not implementing an environmental management system, and 91 were implementing such a system. Descriptive statistics were used to summarise the sample data. The findings of this analysis suggest that the respondents had a favourable attitude toward environmental management systems; they were aware of environmental issues; they perceived themselves and their businesses as able to deal with the barriers to environmental management system implementation; they felt personally obligated to reduce their business‟ environmental impact; and they perceived actions aimed at reducing their businesses‟ environmental impact as socially desirable. To test the hypothesised relationships in the theoretical model, correlation and multiple regression analyses were used. The hypotheses dealing with the relationship between the environmental antecedents and the owner-manager‟s intention to implement an environmental management system, and the actual implementation of an environmental management system, were supported in this study. Thus, the environmental antecedents were found to be positively related to the small and medium-sized business owners‟ intention to implement an environmental management system; to their formal and informal implementation of an environmental management system; and to their practices related to waste management and legal compliance. Empirical evidence to support the hypothesised effect of resource constraints as a moderating variable was found in this study. In terms of environmental values, support was found for the moderating effect of egoistic, altruistic, and biospheric values. In terms of the biographical characteristics of the business owners, significant moderating effects were found for gender and age, but not for education. Gender influenced the relationships between the environmental antecedents, attitude towards an environmental management system and personal pro-environmental norms, and the intention to implement an environmental management system. Age moderated the relationship between subjective pro-environmental norms, waste management, and legal compliance. Given the empirical evidence provided in this study, it is recommended that greater awareness of environmental issues be fostered among small and medium-sized business owners as well as the individuals who influence their decision-making. There is also a need to reinforce the positive business outcomes of environmental management system implementation, as well as the personal and social obligations to protect the natural environment among small and medium-sized business owners.

- 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: The therapeutic potential of stem cells is already being harnessed in clinical trails. Of even greater therapeutic potential has been the discovery of mechanisms to reprogram differentiated cells into a pluripotent stem cell-like state known as induced pluripotent stem cells (iPSCs). Stem cell nature is governed and maintained by a hierarchy of transcription factors, the apex of which is OCT4. Although much research has elucidated the transcriptional regulation of OCT4, OCT4 regulated gene expression profiles and OCT4 transcriptional activation mechanisms in both stem cell biology and cellular reprogramming to iPSCs, the fundamental biochemistry surrounding the OCT4 transcription factor remains largely unknown. In order to analyze the biochemical relationship between HSP90 and human OCT4 we developed an exogenous active human OCT4 expression model with human OCT4 under transcriptional control of a constitutive promoter. We identified the direct interaction between HSP90 and human OCT4 despite the fact that the proteins predominantly display differential subcellular localizations. We show that HSP90 inhibition resulted in degradation of human OCT4 via the ubiquitin proteasome degradation pathway. As human OCT4 and HSP90 did not interact in the nucleus, we suggest that HSP90 functions in the cytoplasmic stabilization of human OCT4. Our analysis suggests HSP90 inhibition inhibits the transcriptional activity of human OCT4 dimers without affecting monomeric OCT4 activity. Additionally our data suggests that the HSP90 and human OCT4 complex is modulated by phosphorylation events either promoting or abrogating the interaction between HSP90 and human OCT4. Our data suggest that human OCT4 displays the characteristics describing HSP90 client proteins, therefore we identify human OCT4 as a putative HSP90 client protein. The regulation of the transcription factor OCT4 by HSP90 provides fundamental insights into the complex biochemistry of stem cell biology. This may also be suggestive that HSP90 not only regulates stem cell biology by maintaining routine cellular homeostasis but additionally through the direct regulation of pluripotency factors. , Thesis (PhD) -- Faculty of Science, Biochemistry and Microbiology, 2015

- 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: Small and Medium Size Enterprises (SMEs) are considered a vital catalyst for economic growth and a source of job creation. In South Africa, with the high levels of unemployment, the contribution made by SMEs is of particular importance. However this sector of the economy is plagued by a high rate of business failure. In an effort to improve the current situation, this study sought to identify which business practices and entrepreneurial traits are present in SMEs in the Eastern Cape that may enhance business performance. The research was carried out amongst SMEs in the Eastern Cape however the results and recommendations of the study can be applied to SMEs in other parts of the country. The research methodology employed in this study was a quantitative approach. A web-based survey was distributed to potential respondents. The criteria used in identify potential respondents for the purpose of this study was that, the SME had to have less than 200 employees and been in business for more than three years. A combination of snowball and convenience sampling was used to select the sample. The researcher developed a conceptual framework using the literature as basis. The survey was distributed to 40 potential respondents. A total of 21 responses were received which translates to a 51 percent response rate. Data analysis was performed by means of descriptive and inferential statistics. The study confirmed the existence of a significant relationship between the independent variables being human resource management, accounting, technology, internal controls and entrepreneurial traits and the dependent variables being business performance. The study affirmed the notion that certain business practices and entrepreneurial traits should be prevalent in a SMEs business in order to enhance business performance. The findings of this study are such that these business practices should be present however the variables highlighted here are not absolute as there are other business practices that are of equal importance.

- Description: In this project, the researcher evaluates revenue collection and allocation challenges faced by South African Municipalities in the case of NDLAMBE Local Municipality and this research project consist of five Chapters. Chapter one introduces and outlines the setting of the study and also provides the problem statement, research questions, research objectives and significance of the study. The chapter further clarifies the key concepts and terms that were used in the study, delimitation and limitations of the study. Chapter two provides a critical discussion of the concept of revenue collection and allocation, focusing on the various perspective of revenue. A source of municipal revenue and revenue collection and allocation model is explained as well as theoretical framework that guides it. Chapter three gives an account of the research design and methodology used in the study and in this study the researcher used the qualitative research approach as a data collection technique and document surveys were used because it is cheap and it saves time. The chapter also highlights the revenue collection and allocation applicable to the study and conclude by discussing the data analysis techniques that were used in the empirical study. Chapter four dealt with the data analysis of data collected presentation and discussion of the results and the researcher analyzed data using the filtering technique and content analysis. Chapter five drew conclusions and made scientific recommendations based on the research findings.The municipality is largely dependent on grants from upper spheres of government and generate less than 20 percent of current expenditures from own resources. As a whole, the revenue collection and allocation challenge of the NDLAMBE Local Municipality, given the current scenario of flows, is a reason for concern. Due to historical and political factors, local governments in South Africa differ substantially in terms of potential revenue base, but it may be that in many cases potential revenue is not exploited and that the high level of dependency on grants, high level of bad debts and lack of political will to be more self-reliant is the result of poor revenue in NDLAMBE Local Municipality.

- 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 research is based on reflections of various practitioners and their views on how public participation processes may or may not contribute to effective EIA decisions. It is therefore grounded in what is described as practitioner-based research. To study comparative development activities effectively, one must draw on many disciplines and construct a balanced understanding of historical and contemporary development processes. No single conventional disciplinary area of research is able to integrate the issues of public participation, EIA and decision-making in the context of the current development debate. The emergence of Trans-disciplinary areas of research allows for such integration. The Africa Earth Observatory Network (AEON) institute creates the space for this study to achieve an integrated response to the question of the effectiveness of public participation in EIA and decision-making. This further creates the opportunity to contribute and expand the growing body of knowledge and literature of public participation in the earth stewardship science discipline. Making use of triangulation, this study fulfils four major tasks: firstly, an assessment is made on the historical and theoretical importance, process and outcome of both EIA and public participation internationally and in South Africa. Secondly, three prominent case studies (i) the Coega IDZ, (ii) the Pondoland N2 Toll Road, and (iii) the anticipated Hydraulic Fracturing in the Karoo each focusses on concerns of an environmental, socio-economic, and political nature to assess if the public participation process has had influence, if any, on the final decisions for these projects to go-ahead. Thirdly, a survey was conducted to establish the views and perceptions of practitioners in the EIA and public participation domain on the effectiveness of public participation in EIA processes. Lastly, face-to-face interviews were conducted with various ‘pracademics’, i.e. consultants, practitioners, government, and non-governmental officials to establish their views on how public participation may or may not influence EIA decisions. Utilising the International Association for Public Participation’s (IAP2) participation spectrum as an evaluation tool, this research explores thirteen key criteria normally attributed to effective public participation. This provides a scale (inform, involve, consult, collaborate) to assess whether public participation in EIA in South Africa is least effective (inform) or most effective (collaborate). My research confirms that in South Africa an enabling environment to address impacts on our environment is emerging. One of the main challenges remains putting in place robust, clear and effective regulations, models or approaches that provide for effective public participation and decision-making in EIAs. My research also suggests that the legislation on which EIA is based cannot by itself guarantee the effectiveness of public participation processes. In practice, EIA is an institutional process of power division between different actors, and the practitioner or ‘pracademic’ has to play a more fundamental role to ensure effectiveness and fairness in the public participation process. Academic commentators should therefore call for new approaches that emphasise collaborative interaction between decision-makers and the public as well as deliberation amongst participants.
