- Description: This research looks at the process of women’s empowerment in post- 1994 Rwanda, with special focus on twelve cooperatives working in Mayaga region and the way these cooperatives empower women, their households and the community at large. Traditional Rwandan society has been always bound by patriarchy which has not valued the reproductive roles of women as economically productive in their households and the society as a whole. On the one hand, this understanding was reversed in the post-1994 Rwanda by the commitment of the government to gender equality at the highest level of political leadership through progressive policies and legislation. On the other hand, in Mayaga region, cooperatives brought about socio-economic development and changed relationships of gender and power in a patriarchal post-conflict society. The findings from cooperatives in Mayaga region show that to prevent women from reaching their full potential is economic folly. If women are empowered, they can generate important development outcomes such as improved health, education, income levels and conflict resolution. The findings further indicate how women’s empowerment is determined by the livelihood strategies women adopt themselves to respond to their vulnerability, and by the ways in which they express their agency in making a living in a sustainable way, with the available community assets that they have access to (financial, social, human, natural and physical). This research highlights that the accessibility of the community assets used by women in Mayaga region and in Rwanda as a whole is also determined by policies, institutions and processes that are able to influence their livelihoods positively.

Wolfgang Koeppens auseinandersetzung mit der tradition: aspekte der intertextualität in der so genannten nachkriegs‐trilogie

- Description: Wolfgang Koeppen’s three post‐war novels have often been called a trilogy, purely based on their publication in rapid succession in the early 1950s. This study establishes a connection between the works by looking at their roots in Irish, Anglo‐American, French and German modernism, and shows up links between Wolfgang Koeppen, James Joyce, E.E. Cummings, Charles Baudelaire and Thomas Mann. This comparative analysis concludes, by integrating socio‐political factors of life in West Germany after World War II, that Koeppen transcends the modernist tradition – the fact that modernism has become tradition, i.e. it has become “classic”, in contradiction to being “modern”. Koeppen’s texts do not only allude to and build on classic texts and refer to stylistic and narrative modernist elements such as stream‐of‐consciousness and sketching a fragmented society in turmoil; the very act of recurring to myths and texts of the Western canon in order to depict the disaffected individual is an almost post‐modern one.

Witwatersrand genesis: a comparative study of some early gold mining companies, 1886-1894

- Description: Preface: For anyone standing on the ridge of the Witwatersrand on a spring day in September 1886 the sight immediately to the south represented a hive of activity and hope. Nearly a hundred years later ample evidence stretches away on both sides of the watershed to confirm the fulfilment of those early sentiments. It is, nevertheless, all too easy to ignore the struggles and failures which marked the beginnings of the world's greatest gold field in the light of its subsequent abundant success. Only when attention is turned to the individual companies formed to exploit the discovery does the true picture emerge of the lack of adequate technological and managerial knowledge amongst the early pioneers and of the financial frailty of their companies. The object of this thesis is to shed light on these beginnings by reviewing the histories of four of the earliest companies established to work the main reef. The approach adopted is to scrutinize the material available with a view to determining the motivations and actions of the managements of the various companies with regard to their economic environment, whether within or without the individual company. Clearly, the availability of information is a major determinant of the success of any such venture and this was particularly so in the case of the companies considered. With the exception of the Barlow Rand Limited holding of the H. Eckstein and Company Archives, which offers an integral coverage of that firm's dealings with the emerging industry, and which is certainly the most comprehensive source of information available to the researcher, little material relating to specific gold mining companies has survived. Under these circumstances it was necessary to rely heavily for information on the local press. These newspapers proved an invaluable source in this regard. As a mining camp with a limited capacity for generating newsworthy incidents, the newspapers of early Johannesburg found an eager readership for information about the industry which lay at the heart of the community. For their part, the managements of the various mining companies found in the pages of the local press an outlet for intelligence both true and false; the press was a useful vehicle for the publication of directors' and annual reports to meet a wider audience, but similarly it could be and was used to disseminate 'spectacular' reports calculated to influence the status of a company's stock on the local share market. As a research source the press has thus to be approached with caution but its value, if the warning is heeded, is in no way diminished. Beyond these two sources the next most valuable accumulation of data on the early industry is "The Gold Fields Collection" housed in the Cory Library for Historical Research at Rhodes University. As a collection it is far from complete and it is to be hoped that the donors will in future see fit to augment it with further material as this becomes available. It neverthess proved an invaluable source for the investigation of at least one of the companies of the study and for a general background to the industry.

William Blake’s animal symbols: tensions and intersections between science and allegory In Eighteenth-Century attitudes towards animals
- Authors: Singh, Jyoti

- Description: This thesis explores the tensions and intersections between science, allegory, and related eighteenth-century attitudes towards animals in William Blake’s poetry through detailed analysis of individual animal symbols and tropes. It will focus specifically on the period between 1794 and 1820, to coincide with the dates of Blake’s major works. Chapter One outlines Blake’s key philosophies, concentrating on his particular approach to symbolism. By rejecting certain Enlightenment ideals and beliefs surrounding allegory, Blake created his own form of the literary tradition, and the subjects and symbols of his poetry clearly demonstrate shifting allegorical frames. The chapter also explains why he argued for the recognition, and even valorisation, of the imaginative faculty, or “Poetic Genius”, in an era which accepted reason and rational thinking as one of the main means of apprehending the world. Chapter Two considers the significance of Blake’s use of predatory animals in the SONGS Of INNOCENCE and Of EXPERIENCE. In focussing on symbolic animals, the chapter assesses whether the ‘real’ animals (with all their scientific associations) are alluded to, and the extent to which they influence their symbolic counterparts. In choosing these symbols to represent key themes throughout his oeuvre, Blake drew on some familiar associations and contemporary attitudes towards animals, but offered no critique of society’s attitudes to animals. Chapter Three identifies and analyses the “fragments of Eternity” represented in the contraries of “Good” and “Evil”, and “Energy” and “Reason” embodied by the animals in THE MARRIAGE of HEAVEN and HELL. The symbols’ division between “Reason” and “Energy” develops an understanding of the complex attitudes towards animals, both in Blake’s mind, and in that of the eighteenth-century British public. Chapter Four is concerned with Blake’s depictions of the Worm and Serpent in his poetry, and how his conception of “Beulah” provides more insight into these symbols and their functions. It also grapples with Rod Preece’s argument that the poet recognised the sanctity and divinity in all forms of life, and sought to endorse these beliefs through his animal symbols. As the thesis illustrates, though, Blake is not arguing for the sanctity of all life to be upheld, nor does he see any divinity in the beings and objects found in nature. Sanctity and divinity are constructs of the imagination, and it is through exercising the imaginative faculty - the “Poetic Genius’’ - along with our senses and instincts, that we are able to make sense of the world. The study thus concludes by considering the extent to which ‘real’ animals intrude upon Blake’s oeuvre, and attempts to determine the value of reading the symbols through an “animal studies” paradigm. It also argues that ‘real’ animals are inseparable from their cultural and symbolic representations, because these are the only means of interpretation we have.

White writers and Shaka Zulu

- Description: The figure of Shaka (c. 1780-1828) looms massively in the historical and symbolic landscapes of Southern Africa. He has been unquestioningly credited, in varying degrees, with creating the Zulu nation, murderous bloodlust, and military genius, so launching waves of violence across the subcontinent (the "mfecane"). The empirical evidence for this is slight and controversial. More importantly, however, Shaka has attained a mythical reputation on which not only Zulu self-conceptions, but to a significant degree white settler self-identifications have been built. This study describes as comprehensively as possible the genealogy of white Shakan literature, including eyewitness accounts, histories, fictions and poetry. The study argues that the vast majority of these works are characterised by a high degree of incestuous borrowing from one another, and by processes of mythologising catering primarily to the social-psychological needs of the writers. So coherent is this genealogy that the formation of an idealised notion of settler identity can be discerned, especially through the common use of particular textual "gestures". At the same time, while conforming largely to unquestioning modes of discourse such as popularised history and romance fiction, individual writers have attempted to adjust to socio-political circumstances; this study includes four close studies of individual texts. Such close stylistic attention serves to underline the textually-constructed nature of both the figure of Shaka and the "selves" of the writers. The study makes no attempt to reduce its explorations to a single Grand Unified Explanation, and takes eclectic theoretical positions, but it does seek throughout to explore the social-psychological meanings of textual productions of Shaka - in short, to explore the question, Why have white writers written about Shaka in these particular ways?

- Description: Within the context of debates concerning the impact of global media on local youth, this study explores how a sample of South African youth responds to texts which were produced internationally, but distributed locally. Recognising the profound rootedness of media consumption in everyday life, the research examines the way these youth, differentially embedded in the South African economic and ideological formation, use these texts as part of their ongoing attempts to make sense of their lives. The study rejects the 'either/or' formulations that often accompany competing structuralist and culturalist approaches to text/audience relationships. Instead, using a combination of quantitative and qualitative research methods, it seeks to highlight the interplay between agency and structure, between individual choice and the structuring of experience by wider social and historical factors. The findings of the study point to the complex individual and social reasons that lie behind media consumption choices, and the diverse (and socially patterned) reasons why local audiences are either attracted to, or reject, global media. These and other findings, the study argues, highlight the deficiencies of the media imperialism thesis with its definitive claims for cultural homogenisation, seen as the primary, or most politically significant, effect of the globalisation of media. As such, this study should be read as a dialogue with those schools of thought that take a more unequivocal point of view on the impact of globalised media culture.

Ways of seeing over time: the construction and imagination of ‘historic separation’ in Israeli and Palestinian cultures

- Identifier: http://hdl.handle.net/10962/474 , vital:19962
- Description: There exists an international consensus that Palestinian and Israeli societies are ceaselessly and essentially acrimonious. This thesis argues that the conceptualisation of ‘historic separation’ in Palestine/Israel is supported and nourished by national narratives that follow classic historicism and a linear trajectory of essentialised culture progressing over time. Given these patterns in historiography and cultural expressions, conceptualisations of the future are argued to be dominated by the ‘overdetermined’ and ‘sacralised’ pasts that arrest the ability to conceive of alternative horizons. These national narratives are analysed borrowing from the theorisation of Edward Said on hegemonic culture, and Ranjit Guha’s Subaltern critique of historicism. Zionism is argued to function as a cultural hegemony that operates in a mercurial, selfsustaining and vibrant manner that has the effect of what this thesis terms ‘centrifugal magnetism’ on discourse in the region. Palestinian national narratives are held to be in tangential relation to Zionism (a classic colonial master-narrative), thus entering into a ‘terrible embrace’ of destructive colonial/postcolonial repetition that tends towards violent conflict and the discrimination of minorities. This thesis then proposes a ‘way out’ of this historiographical pattern that is argued to tangibly inform the cultural fabric of the region. By drawing on the later works of Mahmoud Darwish, Mustaffa Hallaj and Said, it is proposed that there are traces of a notion of self and community that can be described as postnational. This demands a reconstruction of narratives of the past in the region in a pluralistic fashion that is based upon shared exilic identity in flux over what Darwish termed an ‘open historical space’. Crucially, this alternative postnational narrative opens up conceptualisations of the future and is founded upon a renewed disposition to temporality. This thesis thus concludes by proposing that an understanding of temporality as ‘ecstatic’ and essential to being (Martin Heidegger) should be included as a crucial consideration for the end to conflict and the attainment of just and equitable futures.

Wax secretion in the Cape honeybee (Apis mellifera capensis esch.) in relation to juvenile hormone and age polyethism

- Description: Wax secretion in worker honeybees is significantly related to the age of the worker and, while the secretion pattern remains the same, the absolute amount of wax secreted varies seasonally. Comb building festoons, previously thought to be the site of wax secretion, contain only a fraction of the newly-secreted wax in the nest. Festooning behaviour was also found to be seasonal. The amount of wax secreted by workers was significantly affected by hive. Although age-related changes in behaviour and physiology of worker honeybees appears to be modulated by juvenile hormone (JH), wax secretion is not dependent on JH. Manipulating JH III titres by injecting the hormone and manipulating the only source of the hormone (the corpora allata: CA) did not affect wax secretion. Increasing haemolymph JH titre shortly after ec1osion did not affect the amount of wax produced by workers aged 3 to 21 days, nor could a critical period be found during which elevated hormone titres would affect the rate of wax secretion. Allatectomy of newly eclosed workers did not affect wax production. Removing the putative neural feedback inhibition on the CA did not result in a change in wax production. Implanting CA from older workers into younger workers had no significant effect. Methoprene, a widely-used JH analog, caused reduced wax secretion in workers. It is suggested that methoprene poisons worker honeybees. The results obtained are consistent with an alternative model for wax secretion proposed by Butler (1954). The methodological problems found in this work are present in many other studies. When viewed in this light, the role of JH in polyethism appears dubious and there are alternative models of polyethism that do not have these shortcomings.

Comb building festoons, previously thought to be the site of wax secretion, contain only a fraction of the newly-secreted wax in the nest. Festooning behaviour was also found to be seasonal. The amount of wax secreted by workers was significantly affected by hive. Although age-related changes in behaviour and physiology of worker honeybees appears to be modulated by juvenile hormone (JH), wax secretion is not dependent on JH. Manipulating JH III titres by injecting the hormone and manipulating the only source of the hormone (the corpora allata: CA) did not affect wax secretion. Increasing haemolymph JH titre shortly after ec1osion did not affect the amount of wax produced by workers aged 3 to 21 days, nor could a critical period be found during which elevated hormone titres would affect the rate of wax secretion. Allatectomy of newly eclosed workers did not affect wax production. Removing the putative neural feedback inhibition on the CA did not result in a change in wax production. Implanting CA from older workers into younger workers had no significant effect. Methoprene, a widely-used JH analog, caused reduced wax secretion in workers. It is suggested that methoprene poisons worker honeybees. The results obtained are consistent with an alternative model for wax secretion proposed by Butler (1954). The methodological problems found in this work are present in many other studies. When viewed in this light, the role of JH in polyethism appears dubious and there are alternative models of polyethism that do not have these shortcomings.

- Description: Water regulators and policymakers around the world are increasingly influencing water systems towards efficiency and sustainable consumption. In pursuit of these, most regulators mainly use traditional economic-analysis methods to benchmark water utilities and elicit water-service preferences. There have been discussions of several other techniques that extend the commonly used traditional economic analysis tools in the literature. Regardless of these discussions, the practical application of new economic analysis tools in the water sector remains relatively low. This study intends to extend the existing literature by providing more robust methods that could be useful to water regulators. The study asks four research questions to shed light on whether more robust methods are the way forward in water regulation. More precisely, the study investigates the consistency of efficiency scores obtained from the data envelopment analysis (DEA), stochastic frontier analysis (SFA) and stochastic non-parametric envelopment of data (StoNED) techniques on a sample of South African water utilities. Additionally, the study examines the impact of status quo bias, presentation format and response time on results from discrete choice experiments conducted using a case of the South African water sector. The study reports four main findings. First, we find that the StoNED method (based on the methods of moments estimator) outperformed both SFA and DEA. However, SFA outperformed StoNED, when the latter was based on the pseudolikelihood estimator. Second, we find that including a partially relevant status quo reduced status quo bias but did not significantly affect empirical estimates. Major differences are noted in the marginal willingness to pay (MWTP) estimates reported for one of the sub-samples. Third, we find that presenting attributes and levels using the visuals format generated more statistically significant coefficients than presenting them as text or text-and-visuals. Generally, we find that the presentation format significantly affects choice. Finally, we find that removing fast or slow responses from the sample did not significantly affect both utility function and MWTP results. Based on these findings, the study makes four main recommendations. Firstly, the study argues that StoNED (method of moments estimator) and SFA are more appropriate for estimating efficiency in heterogenous water sectors. The study makes recommendations for future studies that seek to do a methodological cross-checking of the three efficiency analysis techniques in the water sector. Secondly, the study argues that a text-and-visuals experiment improves choice task clarity and yields more robust estimates. Thus, more research on the effects of presentation formats is required in environmental economics so that guidelines on developing valid presentation formats for choice tasks can be established. Finally, the study argues against the exclusion of fast and slow responses from the dataset; and recommends approaches for future studies that investigate the impact of response time on choice.

- Description: This study is premised on the assumption that empowering the small-scale farmers in securing property rights and enforcement of these rights are the prime movers of agricultural development. Logically, it follows that by empowering small-scale farmers and giving them access to resources such as credits, subsidies and extension services the state can play a mediating role in transforming the agricultural land scape in Lesotho. Unless farmers are empowered the water resources in Lesotho will continue to serve the interest of the rent-seeking elite. Given the nature of the issues under investigation, the mixed research methodology (the use of both qualitative and quantitative methods) was used as a method of inquiry in order to get a deeper understanding of the phenomenon of water resources management and its subsequent impact on small scale farming in the rural areas of Lesotho. Both methods played a complimentary role by capitalising on both their strengths and weaknesses so as to provide various dynamics and linkages between the two variables of water resources management and small scale farming. The material condition of small scale farmers is intrinsically associated with the active state mediation in agriculture. Yet, the adopted Integrated Water Resources Management (IWRM) approach is still to materialise. This thesis, thus, argues that there is a need for a more holistic integrated water resources management framework that is livelihoods based and re-emphasises the need for conserving the ecosystem. Therefore, implementing a more holistic integrated water resources management approach is critical and vital in improving agricultural production and subsequently the livelihoods of small scale farmers and households. Although this thesis used Lesotho as the case study, it is hoped that the findings may provide tentative answers for other Sub-Saharan countries on how to properly and efficiently manage water resources so as to boost agricultural production amongst small scale farmers in order to improve human conditions and promote sustainable development in the rural areas.

- Description: The Caledon River Basin is located on one of the most water-scarce region on the African continent. The water resources of the Caledon River Basin play a pivotal role in socio-economic activities in both Lesotho and South Africa but the basin experiences recurrent severe droughts and frequent water shortages. The Caledon River is mostly used for commercial and subsistence agriculture, industrial and domestic supply. The resources are also important beyond the basin’s boundaries as the water is transferred to the nearby Modder River. The Caledon River is also a significant tributary to the Orange-Senqu Basin, which is shared by five southern African countries. However, the water resources in the basin are under continuous threat as a result of rapidly growing population, economic growth as well as changing climate, amongst others. It is therefore important that the hydrological regime and water resources of the basin are thoroughly evaluated and assessed so that they can be sustainably managed and utilised for maximum economic benefits. Climate change has been identified by the international community as one of the most prominent threats to peace, food security and livelihood and southern Africa as among the most vulnerable regions of the world. Water resources are perceived as a natural resource which will be affected the most by the changing climate conditions. Global warming is expected to bring more severe, prolonged droughts and exacerbate water shortages in this region. The current study is mainly focused on investigating the impacts of climate change on the water resources of the Caledon River Basin. The main objectives of the current study included assessing the past and current hydrological characteristics of the Caledon River Basin under current state of the physical environment, observed climate conditions and estimated water use; detecting any changes in the future rainfall and evaporative demands relative to present conditions and evaluating the impacts of climate on the basin’s hydrological regime and water resources availability for the future climate scenario, 2046-2065. To achieve these objectives the study used observed hydrological, meteorological data sets and the basin’s physical characteristics to establish parameters of the Pitman and WEAP hydrological models. Hydrological modelling is an integral part of hydrological investigations and evaluations. The various sources of uncertainties in the outputs of the climate and hydrological models were identified and quantified, as an integral part of the whole exercise. The 2-step approach of the uncertainty version of the model was used to estimate a range of parameters yielding behavioural natural flow ensembles. This approach uses the regional and local hydrological signals to constrain the model parameter ranges. The estimated parameters were also employed to guide the calibration process of the Water Evaluation And Planning (WEAP) model. The two models incorporated the estimated water uses within the basin to establish the present day flow simulations and they were found to sufficiently simulate the present day flows, as compared to the observed flows. There is an indication therefore, that WEAP can be successfully applied in other regions for hydrological investigations. Possible changes in future climate regime of the basin were evaluated by analysing downscaled temperature and rainfall outputs from a set of 9 climate models. The predictions are based on the A2 greenhouse gases emission scenario which assumes a continuous increase in emission rates. While the climate models agree that temperature, and hence, evapotranspiration will increase in the future, they demonstrate significant disagreement on whether rainfall will decrease or increase and by how much. The disagreement of the GCMs on projected future rainfall constitutes a major uncertainty in the prediction of water resources availability of the basin. This is to the extent that according to 7 out of 9 climate models used, the stream flow in four sub-basins (D21E, D22B, D23D and D23F) in the Caledon River Basin is projected to decrease below the present day flows, while two models (IPSL and MIUB) consistently project enhanced water resource availability in the basin in the future. The differences in the GCM projections highlight the margin of uncertainty involved predicting the future status of water resources in the basin. Such uncertainty should not be ignored and these results can be useful in aiding decision-makers to develop policies that are robust and that encompass all possibilities. In an attempt to reduce the known uncertainties, the study recommends upgrading of the hydrological monitoring network within the Caledon River Basin to facilitate improved hydrological evaluation and management. It also suggests the use of updated climate change data from the newest generation climate models, as well as integrating the findings of the current research into water resources decision making process.

- Description: This study set out to investigate the structuring, recontextualisation and circulation of waste management knowledge in the South African environmental Expanded Public Works Programme (EPWP) Waste Management Projects. In this thesis these projects also referred to as the Working on Waste (WoW) programme or focus area within the Environmental Protection and Infrastructure Programme (EPIP) hosted by the National Department of Environmental Affairs. Expanded Public Work Programmes are a strategy used by governments to address unemployment and in South Africa; the programmes also seek to address a need for skills development. In this study, the focus is on EPWP waste management knowledge, training programmes and activities only. With waste management knowledge as the core interest, the focus of the investigation was on knowledge circulation of waste management via informal (participation in the project) and formal training of workers at Level 2 National Qualifications Framework (NQF). The study started by firstly investigating what waste management knowledge is produced in the Field of Production via scientific research and policy. It then studied how this waste management knowledge is recontextualised into qualifications and skills programmes designed in the official recontextualising field and learning materials and training programmes designed and offered in the professional recontextualising field. The study also focused on the knowledge of workers and their experience of training in the EPWP workplaces, with an emphasis on rural workplaces. This is where the Department of Environmental Affairs (DEA) is placing emphasis on training for job creation, empowerment and skills development, and it is also where a number of EPWP Working on Waste programmes are being implemented. The aim was also to develop an understanding of how knowledge circulates amongst learners in training sessions and in workplaces. To do this, I drew on Bernstein’s theory of the pedagogical device which provides theoretical lenses and a language of description to explain how knowledge is recontextualised from the field of production to the field of reproduction. To investigate the structuring of this knowledge by official and pedagogical recontextualisers, I drew on the work of Maton, who offers a Legitimation Code Theory to explain the principles structuring knowledge, of which I used specialisation and semantics (two of his suite of knowledge structuring principles) for analysis. The questions that guided the study throughout were: 1. What is the structure of legitimate knowledge and knowers in waste management? 2. What are the underlying principles underpinning knowledge and knowers in waste management? 3. How is the knowledge recontextualised in waste management training qualifications, documents and manuals for worker training at NQF Level 2? 4. How is the knowledge reproduced and evaluated in the waste management EPWP training activities (formal) and workplaces (informal)? 5. How does waste management knowledge circulate amongst the workers in the EPWP training activities and workplaces? For this study I used the case study method, focusing only on one field or DEA EPWP focus area (waste management) and one programme (EPWP Working on Waste), looking in more depth at two cases (two similar types of projects) within the EPWP Working on Waste programme, though they are situated in different areas and though I could only carry through observations of actual workplace training in one of the two sites due to contextual circumstances. The first project was situated in the Amathole District Municipality while the second one was situated in the Chris Hani District Municipality, both of which are in the rural towns of the former Transkei region in the Eastern Cape, South Africa. This area has been at the forefront in accessing funding for these projects due to the level of poverty surrounding these towns and the inability of the local government sphere to deliver on its mandate in the region. Data was collected through document analysis, questionnaires, interviews and observations. Documents analysed were research documents produced by researchers at the level of production as well as legal frameworks guiding waste management processes in this country. Qualifications and Unit Standards at Level 2, as well as training materials designed by providers were analysed. Training in one of the projects was observed and workers in both sites were interviewed twice. The main finding of the study is that waste management knowledge is characterised by interdisciplinarity and a strong epistemic relation which emphasises procedural and technical forms of knowledge. The study found that the knowledge constructed in the field, as well as the policies, qualifications and training programmes are all consequently characterised by a strong epistemic code (ER+) and a weak social relations code (SR-). The study also identified a ‘code clash’ with the knowledge of workers in rural towns whose knowledge and experience of waste management was found to reflect a strong social relation (SR+) and weak epistemic code (ER-), a pattern which was traced back to a similar code in waste management knowledge at home and school (i.e. workers’ prior knowledge and learning experiences). This created difficulties for the trainers who sought to use strategies of descending from the abstract to the concrete in various ‘descending’ semantic waves that tended to move from high levels of semantic density (SD+) to lower levels of semantic density (SD-) as the training provider sought to contextualise a range of concepts. This was the main strategy identified for mediating waste management knowledge reflecting a dominant pattern of SD+/SG- to SD-/SG+ (with SG meaning semantic gravity). This shows that the trainer seldom started mediating concepts from the basis of workers’ prior knowledge and experience and observations showed little responsiveness from workers resulting from this strategy. Despite this, the study found that workers did develop an improved understanding of specialised waste management knowledge over time, especially through observing and doing more complex tasks in the workplace. The study offers a model for addressing the pedagogical difficulty identified around the code clash, and suggests that further attention needs to be given to ‘ascending’ from the concrete to the abstract in pedagogical practices. The study also pointed to the need for a more inclusive knowledge framework for waste management training, especially in the field of recontextualisation (both the official and pedagogical recontextualisation fields) to extend possibilities for workers to learn more about economic potential and access routes into more sustainable jobs. It identifies the need for a more systemic approach to waste management in rural towns and municipalities, improved compliance and also proposes that better waste management practices are modelled to avoid performative contradictions between the knowledge promoted in the field of production and the official and pedagogical recontextualising fields and the field of reproduction, where workers are learning this knowledge via a mix of accredited training and exposure to participation in waste management practices. This study contributes to new knowledge in that it offers an epistemically grounded and theorised pedagogical process model for Level 2 Waste Management Training (in the EPWP programmes, but potentially also more broadly) that accords with the need for a strong epistemic relation code (ER+) embodied in the need for learning scientific and technical waste management knowledge and procedures. It also addresses workers’ needs for greater epistemic access and participation in knowledge building and application of waste management knowledge in praxis as per the purpose of the EPW training programmes, thereby potentially opening up more sustainable learning pathways for them out of poverty through the EPWP training opportunities. The study has pointed to key areas for further research, including further research on the proposed model, further research into Level 2 pedagogical practices and further research into the foundations of waste management learning in schools. Most of the workers who were participating in the training in the EPWP programmes were educated at above Level 2 before participating in the projects, yet their knowledge and experience of waste management was mostly based on everyday knowledge, pointing to an absence of adequate waste management education in schools in rural contexts in South Africa. The study has also made various recommendations for improving waste management education and training at Level 2 in EPWP programmes in rural areas in particular (but potentially also more widely), notably the need to develop a more inclusive knowledge framework that includes historical and economic knowledge more explicitly at all levels of the recontextualisation process; improved pedagogical and assessment practices that take better account of learners knowledge and experiences in knowledge building processes; and giving attention to structural and systemic approaches to waste management in rural areas to avoid performative contradictions that arise between the knowledge being promoted in the field of production and the field of reproduction and the actual context of waste management.

This shows that the trainer seldom started mediating concepts from the basis of workers’ prior knowledge and experience and observations showed little responsiveness from workers resulting from this strategy. Despite this, the study found that workers did develop an improved understanding of specialised waste management knowledge over time, especially through observing and doing more complex tasks in the workplace. The study offers a model for addressing the pedagogical difficulty identified around the code clash, and suggests that further attention needs to be given to ‘ascending’ from the concrete to the abstract in pedagogical practices. The study also pointed to the need for a more inclusive knowledge framework for waste management training, especially in the field of recontextualisation (both the official and pedagogical recontextualisation fields) to extend possibilities for workers to learn more about economic potential and access routes into more sustainable jobs. It identifies the need for a more systemic approach to waste management in rural towns and municipalities, improved compliance and also proposes that better waste management practices are modelled to avoid performative contradictions between the knowledge promoted in the field of production and the official and pedagogical recontextualising fields and the field of reproduction, where workers are learning this knowledge via a mix of accredited training and exposure to participation in waste management practices. This study contributes to new knowledge in that it offers an epistemically grounded and theorised pedagogical process model for Level 2 Waste Management Training (in the EPWP programmes, but potentially also more broadly) that accords with the need for a strong epistemic relation code (ER+) embodied in the need for learning scientific and technical waste management knowledge and procedures. It also addresses workers’ needs for greater epistemic access and participation in knowledge building and application of waste management knowledge in praxis as per the purpose of the EPW training programmes, thereby potentially opening up more sustainable learning pathways for them out of poverty through the EPWP training opportunities. The study has pointed to key areas for further research, including further research on the proposed model, further research into Level 2 pedagogical practices and further research into the foundations of waste management learning in schools. Most of the workers who were participating in the training in the EPWP programmes were educated at above Level 2 before participating in the projects, yet their knowledge and experience of waste management was mostly based on everyday knowledge, pointing to an absence of adequate waste management education in schools in rural contexts in South Africa. The study has also made various recommendations for improving waste management education and training at Level 2 in EPWP programmes in rural areas in particular (but potentially also more widely), notably the need to develop a more inclusive knowledge framework that includes historical and economic knowledge more explicitly at all levels of the recontextualisation process; improved pedagogical and assessment practices that take better account of learners knowledge and experiences in knowledge building processes; and giving attention to structural and systemic approaches to waste management in rural areas to avoid performative contradictions that arise between the knowledge being promoted in the field of production and the field of reproduction and the actual context of waste management.

- Description: Walking as a way to experience a place is a relatively understudied area of phenomenological study. Furthermore, globally (the world) and locally (South Africa) the study of the experience of tertiary education institutions as walked environments is minimal (see Puig-Ribera et al., 2008; Speck et al., 2010; Mtolo, 2017). However, the events of the South African #MustFall moment – especially the #RhodesMustFall part of the moment and how it began with the desecration of a statue that was walked past and found to be a misplaced artefact in a society that is in postcolonial/post-Apartheid times and space – highlighted the pressing need to study the experience of the university as a place through which habitual walking takes the student through moments of movement, rest, and encounter that are a highly consequential way in which placeness is experienced. This study is a way to document how students at Rhodes University experience the university’s placeness quality, through habitual walking, in an example of the way in which a place is experienced through moments of movement, rest, and encounter. For this study in-depth mobile interviews were conducted with 12 student participants from Rhodes University. The interviews were video-recorded as the participants talked while traversing through habitually walked areas of the campus that are the meaning-infused spaces which make up the Rhodes University that they traverse through on a daily basis. The dissertation found that in the experience of Rhodes University, through habitually walking its placeness, people experience moments of movement, rest, and encounter that are highly targeted and personalised. The experience of the Rhodes University campus is an experience of people and the built-up and decorated environment along similar lines. People bring to the experience of their walked space past experiences which inform consequentially how any space that is walked is experienced. People further employ strategies to ensure that the experience of walking a space is more to their desired quality as an experience, which ends up being meaningful and most likely to affect future instances of walking through meaning-infusing and meaning-infused space. Ultimately, the habitual walking of Rhodes University consequentially informs the relationship between students and Rhodes University’s placeness, as the walking is a way of learning how to be within a placeness that is engaged through alternating moments of movement, rest, and encounter that incrementally ‘open’ for experience Rhodes University in such a targeted manner that every student eventually has their personal and customised Rhodes University by virtue of it being just those sites and situations which have been engaged through habitual walking.

- Description: This thesis examines an aspect of economic and technological history which has been little explored in South African history. It argues that the military subjugation and the economic development of the Cape Colony, and particularly of the Eastern Cape, were contingent upon good transportation. The geography of the country, which included relatively impassable mountains and numerous often flooded rivers, necessitated bridges as well as roads. Both were expensive. As a leader in industrial technology, Britain was well placed to extend bridge-building skills to its colonies. This thesis examines the processes by which a small and undeveloped colony strove to create an efficient technological infrastructure. As wagon traffic increased through progress, delays in crossing rivers became a hindrance leading to agitation for bridges. It will be shown that the construction of wagon bridges over the numerous rivers encountered in the Eastern Cape Colony was imperative for the initial free flow of military forces and for later commercial expansion as new towns were established. The eastward expansion was led by the military during the frontier wars followed by the Royal Engineers who built roads and bridges along the eastern frontier. The new Colonial Secretary John Montagu, who arrived in 1843, boosted the colonial finances by overhauling the administration. He established the Central Road Board, an organisation that would drive the building of mountain passes, roads and bridges. The Public Works Department succeeded the Central Road Board and with the financial intervention of the Crown Agents for the Colonies, carried on with an extensive programme of road and bridge building. From the 1870s wagon bridge building lagged behind the huge railway building enterprise in response to the opening up of the diamond and gold mines. The final quarter of the 19th century saw increased bridge building activity in the Eastern Cape with the construction of many iron lattice girder, stone masonry arch and timber trestle bridges. The surviving bridges remain as mute testimony to the skill and expertise of British engineers such as Lewis, Woodifield, Robinson, Fforde, Wakefield, Berkley, Grier, Newey, Westhoven and others.

- Description: Climate variability and change as well as sea level rise poses significant challenges to livelihoods, water and food security in small island developing states (SIDSs) including the Zanzibar Islands. Thus, without planned strategic adaptation, the future projected changes in climate and sea level will intensify the vulnerability of these sensitive areas. This thesis is based on research conducted in two sites located in the north eastern parts of each island, namely Kiuyu Mbuyuni, Pemba Island and Matemwe, Unguja Island. The research focused firstly on assessing the vulnerability of these two coastal communities to climate variability and change and other stressors. This included investigation of (1) the perceptions of fishers, farmers and seaweed farmers regarding climate stressors and shocks and associated risks and impacts, (2) existing and possible future water and food security issues, and (3) household's access to important livelihood assets. This was followed by an exploration of the coping and adaptive responses of farmers, fishers and seaweed farmers to perceived shocks and stresses and some of the barriers to these responses. Lastly, an analysis of the implications of the findings for achieving sustainable coastal livelihoods and a resilient coastal community was undertaken. The general picture that emerges is that local people along the east coasts of both islands are already vulnerable to a wide range of stressors. Although variability in rainfall is not a new phenomenon in these areas, increasing frequency of dry spells and coastal floods resulting from the influence of El Niño and La Niña events exert enormous pressures on local activities (fishing, farming and seaweed farming) which are the crux of the local economy. The main argument of the study is that the nature and characteristics of these activities are the main source of sensitivity amongst these communities and this creates high levels of vulnerability to climate shocks and trends. This vulnerability is evidenced by the reoccurrence of localised food shortages and the observed food and water insecurity. The study found that food insecurity is a result of unreliable rainfall, drought and seasonality changes. These interacted with other contextual factors such as poor soil, low purchasing power and the lack of livelihood diversification options. In addition to exposure to these almost unavoidable risks from climate variability, the vulnerability of the local communities along the east coasts is also influenced by the low level of capital stocks and limited access to the assets that are important for coping and adaptation. Despite this, some households managed to overcome barriers and adapt in various ways both within the three main livelihood sectors (fishing, farming and seaweed farming) as well as through adopting options outside these sectors resulting in diversification of the livelihood portfolio. However, the study found that most of the strategies opted for by fishers, farmers and seaweed farmers were mainly spontaneous. Few planned adaptation measures supported by state authorities were observed across the sites, with the exception of the provision of motorised boats which were specifically meant to increase physical assets amongst fishers, reduce pressure in the marine conservation areas and prevent overfishing in-shore. Furthermore, numerous strategies that people adopted were discontinued when further barriers were encountered. Interestingly, some of the barriers that prevented households adapting were the same ones that forced households that had responded to abandon their adaptations. To increase resilience amongst east coast communities to current and future predicted changes in climate and sea level, the study argues that traditional livelihood activities (fishing, farming and seaweed farming) need to be better supported, and access to a range of livelihood assets improved. This may be achieved through increased access to local sources of water and facilitation of rainwater harvesting, expanding the livelihood options available to people and increasing climate change awareness, and access to sources of credit.

Vitamin E supplementation and secondary metabolites interactions and effects on melanoma growth

- Description: The present study was undertaken to determine the effects and possible mechanism of action of vitamin E succinate on malignant murine melanoma (BL6) and non-malignant monkey kidney (LLCMK) cell growth in vitro. Studies revealed that supplementation of 5, 7 and lOJLg/ml vitamin E succinate significantly inhibited BL6 cell growth, while in LLCMK cells no significant increase or decrease in growth was observed. The actual mechanism by which vitamin E succinate inhibits BL6 cell growth is at present unclear. Studies have suggested a radical or oxidant involvement in a number of degenerative diseases such as cancer, and that supplementation of antioxidant vitamins such as vitamin E may function to reduce cancer cell growth by quenching free radical species and preventing lipid peroxidation. In addition to its antioxidant role in a cell, vitamin E is believed to modulate the activities of various enzymes and metabolites in the eicosanoid pathway. Hence, this study investigated the effects of vitamin E succinate supplementation on free radical and lipid peroxidation levels, as well as the activities of various enzymes and metabolites ill the eicosanoid pathway. Throughout this study, emphasis was placed on BL6 melanoma cells since the magnitude of the relationship between LLCMK growth and the levels of various enzymes and metabolites in the eicosanoid pathway varied considerably from one experiment to another and did not show the consistent trend found with the BL6 cells. A decrease in cell growth was found to be accompanied by a concomitant increase rather than a decrease in the levels of free radicals and lipid peroxidation, suggesting that the growth inhibitory effects of vitamin E succinate on BL6 cells in vitro was not due to its antioxidant properties associated with the vitamin E component, but rather due to one or more of its other potential roles within the cell. This proposal was further strengthened by findings that vitamin E succinate, a non-physiological antioxidant in its esterified form, did not undergo significant cleavage to free vitamin E in the BL6 cells. Vitamin E succinate is believed to modulate membrane bound enzyme activities through physicochemical interactions with membrane lipids and changes in membrane fluidity. Hence, this study investigated the role of vitamin E succinate in modulating the activity of various enzymes and secondary messengers in the eicosanoid pathway. Supplementation of l-lOjLg/ml vitamin E succinate resulted in an overall increase in phospholipase A2 activity while cyclooxygenase and adenyl ate cyclase activities were found to be significantly increased at vitamin E succinate concentrations of 7 and WjLg/ml respectively. A significant increase in" 5-LOX activity was observed a! 10jLg/mi supplementation. The suggestion that vitamin E succinate modulates membrane bound enzyme activities was further strengthened by uptake and cellular distribution studies, which showed significantly higher levels of vitamin E succinate in membrane fractions of BL6 cells when compared with stroma fractions. Another factor which could account for elevated PLA2,-5-LOX and COX activities in BL6 cells as a result of vitamin E succinate supplementation, was that of intracellular calcium levels. Supplementation of BL6 cells with 1-7 jLg/ml vitamin E succinate resulted in an overall increase in intracellular calcium levels. These changes in calcium levels however were positively correlated with changes in PLA2 activity only. Since the rate of prostaglandin synthesis is controlled by phospholipase A2 activity, and net prostagiandin production is dependant on cyclooxygenase activity, the effects of vitamin E succinate supplementation on prostaglandin levels in BL6 cells was determined. Vitamin E succinate supplementation resulted in a significant decrease in prostaglandin D2 levels at vitamin E succinate concentrations of 3, 5, 7 and lOjLg/ml respectively, while prostaglandin F2a levels were significantly decreased at 1-10jLg/ml vitamin E succinate. The increases in prostaglandin E2 and 12 levels were inversely related to BL6 cell growth suggesting that both prostaglandins may act as negative regulators of BL6 cell growth. When comparing prostaglandin E2 levels to prostaglandin 12 levels in BL6 cells, significantly higher levels of prostaglandin E2 were found, suggesting that vitamin E succinate effects were mediated primarily through an increase in prostaglandin E2 levels. Furthermore, prostaglandin E2 levels are believed to modulate adenylate cyclase activity. It is therefore reasonable to conclude that the increased adenyl ate cyclase activity found in BL6 cells was dependant on prostaglandin E2 levels, since increases in prostaglandin E2 levels at 7 and lOjLg/ml vitamin E succinate correlated with an increase in adenylate cyclase activity and cyclic adenosine monophosphate levels. Thus it appeared that the observed inhibitory effects of vitamin E succinate supplementation on BL6 cell growth was not due to the antioxidant properties associated with the vitamin E component of the vitamin E succinate molecule, but was rather mediated in part through a cascade effect initiated by phospholipase A2 activation and archidonic acid release. This initial effect then appeared to result in an increase in cyclooxygenase activity and activation of a prostaglandin E2-adenylate cyclase-cyclic adenosine monophosphate linked system, ultimately altering cyclic adenosine monophosphate levels and inhibiting BL6 cell growth. This was confirmed when BL6 cells were supplemented with indomethacin, a cyclooxygenase inhibitor. Supplementation with the inhibitor resulted in vitamin E succinate having no inhibitory effects on BL6 cell growth. Furthermore, when comparing the levels of prostaglandin ~, adenylate cyclase activity and cyclIC adenosine monophosphate in the indomethacin treated cultures to non-indomethacin treated cultures, markedly lower levels of these metabolites were found in the indomethacin treated cultures. The cause of the increase in free radical and lipid peroxidation levels in BL6 cells following vitamin E succinate supplementation was further investigated. Cyclooxygenase enzymes are believed to generate free radical species and contribute to lipid peroxidation levels during catalytic activity. Markedly lower levels of free radicals and lipid peroxidation in indomethacin treated cultures were found when compared with vitamin E succinate treated cultures alone, suggesting that the increases in free radical and lipid peroxidation levels in BL6 cells supplemented with vitamin E succinate were indirectly due to an increase in cyclooxygenase activity in these cells.

Furthermore, prostaglandin E2 levels are believed to modulate adenylate cyclase activity. It is therefore reasonable to conclude that the increased adenyl ate cyclase activity found in BL6 cells was dependant on prostaglandin E2 levels, since increases in prostaglandin E2 levels at 7 and lOjLg/ml vitamin E succinate correlated with an increase in adenylate cyclase activity and cyclic adenosine monophosphate levels. Thus it appeared that the observed inhibitory effects of vitamin E succinate supplementation on BL6 cell growth was not due to the antioxidant properties associated with the vitamin E component of the vitamin E succinate molecule, but was rather mediated in part through a cascade effect initiated by phospholipase A2 activation and archidonic acid release. This initial effect then appeared to result in an increase in cyclooxygenase activity and activation of a prostaglandin E2-adenylate cyclase-cyclic adenosine monophosphate linked system, ultimately altering cyclic adenosine monophosphate levels and inhibiting BL6 cell growth. This was confirmed when BL6 cells were supplemented with indomethacin, a cyclooxygenase inhibitor. Supplementation with the inhibitor resulted in vitamin E succinate having no inhibitory effects on BL6 cell growth. Furthermore, when comparing the levels of prostaglandin ~, adenylate cyclase activity and cyclIC adenosine monophosphate in the indomethacin treated cultures to non-indomethacin treated cultures, markedly lower levels of these metabolites were found in the indomethacin treated cultures. The cause of the increase in free radical and lipid peroxidation levels in BL6 cells following vitamin E succinate supplementation was further investigated. Cyclooxygenase enzymes are believed to generate free radical species and contribute to lipid peroxidation levels during catalytic activity. Markedly lower levels of free radicals and lipid peroxidation in indomethacin treated cultures were found when compared with vitamin E succinate treated cultures alone, suggesting that the increases in free radical and lipid peroxidation levels in BL6 cells supplemented with vitamin E succinate were indirectly due to an increase in cyclooxygenase activity in these cells.

- Description: This study analyses artworks by contemporary Palestinian artists that respond to visual narratives of division in social space from a perspective grounded in a South African context. The state of Israel is built on Historic Palestine. Political Zionism has created an ideological narrative of division that positions people of the Jewish faith as the rightful heirs to the land on which Palestinians have lived for centuries. In order to execute their vision of an exclusively Jewish nation state, the founding pioneers of political Zionism colonised and ethnically cleansed Historic Palestine, establishing Israel in 1948. To sustain the exclusive claim to Palestinian land, Israel has divided the space and the people in it at every possible level. The greatest testament to these efforts is the Israeli apartheid wall and checkpoint security system that can be described as a monumental visual narrative of division. With each second that passes, Israel claims more Palestinian land and expands on existing fences, walls and barriers. It is no secret that the Occupied Palestinian Territories are rapidly transforming into open-air prisons. Israel has stolen the Palestinian horizon line and replaced it with a concrete wall that blocks out light, vision and optimism. Within the shadows of these conflicted, traumatised sites of division, Palestinian artists seek openings, cracks and loopholes that signal the possibility for physical and psychological transgression of these seemingly impenetrable structures of division. I have developed a creative methodology that can be understood through the metaphor of ‘looking with the skin’ as a way to identify and analyse visual narratives of division and artistic responses to sites of division in Palestinian social space. Looking with the skin combines aspects of participant observation (specifically the emphasis on engaged fieldwork) from the discipline of Anthropology with the method of visual analysis from the discipline of Art History. In my application of this method through primary fieldwork conducted within the Occupied Palestinian West Bank Territory from 2013 and 2014, I have learnt that Israel’s colonisation, military occupation and system of apartheid directly impacts the ability of Palestinian artists to make and disseminate their work as well as the choice of content within their artwork. The artworks analysed in this thesis by the artists Khaled Jarrar, Y ael Bartana, Larissa Sansour, Hasan Darahgmeh, Fareh Saleh and Emily Jacir can be positioned in relation to artworks by artists based within a South African context, namely Thando Mama, Serge Alain Nitegeka and Doung Anwar Jahangeer. In this thesis I present a combination of my own photographic documentation of sites of division with the West Bank OPT in relation to the specific artworks made by the artists mentioned above. In my analysis of the photographic documentation and the artists’ work I highlight similarities, parallels, threads and intersecting narratives that connect different artists to one another and to the sites of division they are responding to within their artistic practice. This study carves a small conceptual pathway through ideological and physical walls from South Africa to Palestine through the study of contemporary art and visual culture.

Versions of confinement: Melville's bodies and the psychology of conquest

- Description: This thesis explores aspects of Melville’s presentation of both the whale and the human bodies in Moby-Dick and human bodies in other important novels. It argues that Melville uses his presentation of bodies to explore some of the versions of confinement those bodies experience, and by doing so, analyses the psychology which subtends that confinement. Throughout Melville’s works bodies are confined, both within literal spatial limits and by the psychology which creates and/or accepts these spatial limits. The thesis argues that perhaps the most important version of bodily confinement Melville addresses is the impulse to conquer bodies, both that of the other and one’s own. It adopts a largely psychoanalytic approach to interpreting bodies and their impulse to conquer, so that the body is seen to figure both in its actions and its external appearance the operations of the inner psyche. The figure of the body is equally prevalent in Melville’s exploration of nationalist conquest, where, as with Manifest Destiny and antebellum expansionism, the psychological and physical lack experienced by characters can be read as motivating factors in the ideology of conquest. A final important strand of the thesis is its argument in favour of a gradual shift in Melville’s interpretation of the value and possibility of genuine communion between human beings and between humans and the whale. One may read Typee as an attempt by Melville to explore the possibility of a this-worldly utopia in which human beings can return to a version of primitive interconnectedness. This exploration may be seen to be extended in Moby-Dick, particularly in Ishmael’s attempts to find communion with others and in some moments of encounter with the whales. The thesis uses phenomenology as a theory to interpret what Melville is trying to suggest in these moments of encounter. However, it argues, finally, that such encounter, or ‘intersubjectivity’ is eventually jettisoned, especially in the works after Moby-Dick. By the end of Melville’s life and work, any hope of an intersubjective utopia he may have harboured as a younger man have been removed in favour of a refusal actually to assert any final ‘truth’ about social, political or even religious experience. Billy Budd, his last body, is hanged, and his final word is silence.

Vernacular radio and peace building in Kenya: a study of popular vernacular radio stations in three conflict-prone regions

- Description: In Kenya, just like in most African countries, ethnicity-related conflicts are a common phenomenon. Often times, the media, especially vernacular radio has been accused of incitement to violence as was in the case of 1994 Rwanda genocide and the 2007 post-election violence in Kenya. As a result, numerous studies have focused on the role that the media, especially vernacular radio plays in perpetuating ethnic conflict, while very little has been done to establish its role in peace building. Therefore, this study was informed by the assumption that the media is a double edged sword; while it can fuel tension and lead to conflict, it can also contribute to peace between conflicting parties. It therefore sought to establish the role that vernacular radio play in peace building in Kenya. The literature reviewed showed that vernacular radio has the potential to promote peace in society. The study was therefore guided by the social responsibility theory which underpins the necessity for the media/ journalist to keep society’s interest as a top priority. This means that the society expects journalists to be accountable, liable and responsible in carrying out their duties. This study utilized both qualitative and quantitative research methods. Using a case study of popular vernacular radio stations in three conflict prone regions in Kenya, the researcher employed content analysis, questionnaires and interviews as tools for data collection. The results indicate that the stations have put in place specific policies aimed at ensuring impartiality in reporting and that journalists adhere to them in their work. The stations also work in partnership with other peace practitioners by developing programs that are aimed at promoting peace within and between communities. Furthermore, the findings indicate that the stations’ journalists largely understand and comply with the sections of the Code of Conduct for the Practice of Journalism in Kenya which addresses the need for responsible conflict reporting. Based on these findings, the study therefore concludes that vernacular radio stations working in conflict prone regions in Kenya play a positive role in peace building. However, the study recommends more specialized trainings for journalists in order for these stations to be more effective in this role of peace building.
