- Description: Aims: It is argued that one’s sense of self is threatened and eroded by mental illness. According to the narrative perspective, one’s personal life narrative is displaced and maintained by a story of illness. However, dialogical self theorists argue that mental illness limits the number of ‘I’ positions available within an individual, resulting in the positions/voices becoming rigid and being dominated by a singular, monological position. The aims of this qualitative study are to attempt to understand and examine psychiatric inpatients’ personal lived experiences of an art group. The goal of the study is to focus on the impact of the art-making process on these patients with regards to the construction of their sense of self. Design: A qualitative research design was used in the study. Method: Four psychiatric in-patient art group members – three male and one female, between the ages of 27 and 40 – were interviewed. A semi-structured interview schedule consisting of sixteen questions focusing on the interviewees’ experiences of the art group was used. The interviews were analysed using an interpretive phenomenological analysis. Results: Three superordinate themes emerged: What the Participants Gained From the Art Group, Sense of Community and Leaving a Mark, and The Experience of Self in the Art group. All three Superordinate themes fall within the participants’ experience of the art group. Conclusion: All four of the participants expressed positive feelings and enjoyment towards the art group. Participation in the art group provided the participants with a sense of pride, achievement and hope within their lives. As a result of participation on the art group, one of the four participants was able to construct a thin alternative experience and sense of self.

- Description: One of Africa’s neglected tropical diseases, African Trypanosomiasis, is not only fatal but also has a crippling impact on economic development. Heat shock proteins play a wide range of roles in the cell and they are required to assist the parasite as it moves from a cold blooded insect vector to a warm blooded mammalian host. The expression of heat shock proteins increases during these heat shock conditions, and this is considered to play a role in differentiation of these vector-borne parasites. Heat shock protein 70 (Hsp70) is an important molecular chaperone that is involved in protein homeostasis, Hsp40 acts as a co-chaperone and stimulates its intrinsically weak ATPase activity. In silico analysis of the T. brucei genome has revealed the existence of 12 Hsp70 proteins and 65 Hsp40 proteins to date. A novel Hsp70, TbHsp70.c, was recently identified in T. brucei. Different from the prototypical Hsp70, TbHsp70.c contains an acidic substrate binding domain and lacks the C-terminal EEVD motif. By implication the substrate range and mechanism by which the substrates are recognized may be novel. The ability of a Type I Hsp40, Tbj2, to function as a co-chaperone of TbHsp70.c was investigated. The main objective of this study was to biochemically characterize TbHsp70.c and its partnership with Tbj2 to further enhance our knowledge of parasite biology. TbHsp70.c and Tbj2 were heterologously expressed and purified and both proteins displayed chaperone activities in their ability to suppress aggregation of thermolabile MDH. TbHsp70.c also suppressed aggregation of rhodanese. ATPase assays revealed that the ATPase activity of TbHsp70.c was stimulated by Tbj2. The targeted inhibition of the function of heat shock proteins is emerging as a tool to combat disease. The small molecule modulators quercetin and methylene blue are known to inhibit the ATPase activity of Hsp70. However, methylene blue did not significantly inhibit the ATPase activity of TbHsp70.c; while quercetin, did inhibit the ATPase activity. In vivo heat stress experiments indicated an up-regulation of the expression levels of TbHsp70.c. RNA interference studies showed partial knockdown of TbHsp70.c with no detrimental effect on the parasite. Fluorescence microscopy studies of TbHsp70.c showed a probable cytoplasmic subcellular localization. In this study both TbHsp70.c and Tbj2 demonstrated chaperone activity and Tbj2 possibly functions as a co-chaperone of TbHsp70.c.

- Description: The teaching profession, like many other professions, has rules and regulations that guide the conduct of its members. Teachers and those who aspire to take up teaching are expected to conduct themselves and discharge their duties in an impeccably professional manner. However, there is concern especially among education authorities regarding unprofessional conduct of some of those employed in schools and colleges. This action research study is a response to this concern. Its goal was to explore issues of professional conduct as part of the induction process of new members entering the teaching profession, and to thereby develop a better understanding of how best to raise student teachers’ awareness around professional conduct issues. The study used a qualitative research framework located in the interpretive paradigm. Three theoretical frameworks informed the design and subsequent analysis of the findings, namely, Burn’s transformational leadership, Mezirow’s transformative learning and Kolb’s theory of experiential learning. Two cycles of workshops around issues of professional conduct were conducted over a period of four weeks with a sample of 40 pre-service student teachers: final year students enrolled in the college’s three year Diploma in Education programme, all members of a science education class. Data collection strategies used were semi-structured interviews, observation and the use of reflective journals, among others. Analysis of the data involved identification of emerging themes and patterns. Initial findings indicate that prior to the commencement of the cycles of action research, participants appeared to have a limited understanding around issues of professional conduct, but that this changed as they participated in the workshops. The data of the study suggest that further steps need to be taken to establish optimal ways of incorporating professional conduct issues into the college’s teaching curriculum.

- Description: This article uses an appraisal analysis of 40 letters to the Daily Sun and The Times newspapers in South Africa to illustrate a reconceptualisation of the Engagement system. It discusses dialogism (Bakhtin 1981), which inspired the creation of the Engagement framework by White (2003), who classified attempts to either align or disalign readers with a writer’s stance. Contrary to the options for dialogic Engagement proposed by Martin and White (2005) and White and Don (2012), the data suggests that not all Engagement strategies carry equal power of alignment, as the framework’s systemic layout implies. This prompts a re-thinking of the Engagement categories as occurring along a continuum of their strength.

- Description: This study is part of a larger research programme that seeks to contribute towards an understanding of South Africa's complex literacy landscape and formulate strategies that may address these particularly in the Foundation Phase. It is a case study of one public primary school in Grahamstown where isiXhosa is used as a medium of instruction until Grade 3, after which the medium of instruction changes to English. This transition is not helped by the little reading that happens in the language at the FP. The learners under study are Grade 3 isiXhosa first language speakers, learning English as a First Additional Language (FAL) with limited exposure to the language. Through a qualitative participatory action research process, the study investigated the extent to which a reading club in general and a responsive reading programme in particular, might develop learners' English vocabulary at this particular school. The value of reading clubs as a vehicle for second language learning as well as the importance of considering learner needs in the development of the reading programme are key contributions this study makes. The study draws on social constructivism as a theoretical framework based on the principle that learning is a social acitvity. Vygotsky (1978) states that language learning (LL) takes place through interactions in meaningful events, rather that through isolated language activities. The process is seen as holistic, that is, each mode of language supoorts and enhances overall language development. Furthermore, LL develops in relation to the context in which it is used, that is, it develops according to the situation, the topic under discussion and the relationship betwwen participants. Language also develops through active engagement of the learners. The role of the teacher or a more competent other is then seen as that of a facilitator in a learning context in which learners are viewed as equally capable of contributing to their learning through learning from and with each other (Holt and Willard-Holt, 2000). Vygotsky's theory of social interaction has been influential in highlighting the important role of social and cultural contexts in extending children's learning. The preliminary results of this study point toward the importance of the learning environment, particularly an informal environment in second language development. The results also highlight the need for learners (a) to be provided with opportunities to engage with meaningful and authentic texts, (b) to be allowed to make their own book choices, (c) to participate in large group, small group and individual activities to enable them to engage with a variety of texts, and (d) to confront vocabulary in a variety of ways through multiple texts and genres.

- Description: Biocultural diversity has been conceptualised as the sum of the world’s differences regarding biological diversity at all levels and cultural diversity in all its manifestations, and their interactions. The concept is often framed in the context of conservation as a retention versus loss model by emphasizing the religious and spiritual values of the natural environment and the positive interactions between traditional indigenous people and conservation of natural ecosystems and indigenous species. On the basis of our research amongst the ‘non-traditional’ amaXhosa in South Africa, we argue that this interpretation is too narrow and that the concept needs to be reappraised in order to capture the dynamic, complex and relational nature of bio-cultural diversity relations. We conclude that the concept involves a complex of human values and practices related to the three main dimensions of biodiversity at landscapes, species and genetic levels.

- Description: Success in business is for the most part defined in financial terms and, because of this, business operations are almost entirely, if not entirely, directed to this end. The principle behind this rationale has been informed by the thought that the best contribution businesses can make to social justice is to focus on the bottom line. By appealing to enlightened self-interest and the high premium people place on freedom, neoliberal economists like Milton Friedman and Friedrich Hayek argue that maximising profits is necessarily socially responsible. And, moreover, that not to pursue this end is socially irresponsible. Social responsibility is the ultimate justification that thinkers such as Friedman and Hayek appeal to when claiming that the business of business is to maximise profit. Yet this position is internally inconsistent. The position is ultimately justified by what is socially just but this means that in fact social justice, and not profit-making, ought to be the end of business. I shall argue that taking this commitment seriously involves rejecting the idea that the aim of business is to maximise profits. This is not to say that businesses should not make profits, rather it implies that this feature is not what ultimately makes them successful. The central contribution of this project is to resolve the contradictions embedded in the traditional approach to business by arguing that the primary aim of business is the promotion of social justice. To this end success in business needs to be redefined so that it reflects the achievement of its ultimate ends and not simply its instrumental means (profit) to the realisation of these aims. We ought then to revise our fundamental assumptions about the structures and policies that are necessary for business to achieve its real end of social justice.

- Description: Loosely following a narrative form and structure, this thesis begins, in chapter one, by considering people who occupy a peripheral position in - or on the fringe of - society. In so doing, it analyses the dichotomy created between centre and periphery, the line between qualities or features that are set up as different or opposed. The chapter begins by contextualising my own engagement with the themes and narratives dealt with. It then looks at the representation and significance of historical and cultural characters such as the tramp and the wanderer, the medieval wildman and the outcast, the madman and the prophet, and relates this to some extent to my own narrative. The dichotomy between culture and nature is thus examined here. The paper then moves on, in chapter two, to examine concerns around landscape, and considers how we engage or separate ourselves from it. The theme of walking is examined closely from an experiential, phenomenological standpoint, especially as an activity which allows greater connection to, and engagement with, the landscape. The relationship between landscape, place, and identity is also explored, looking at how identity is interwoven with connection to place, and, broadly, what this might mean for displaced people. These discussions and ideas are then brought to bear again on my personal narrative. In chapter three I explore again the separation between dichotomous concepts as looked at in chapter one; I examine the separations between, and within, people, as well as between people and their environment. Here, however, the line of separation is explored not as an impermeable barrier, but as a liminal space of potential and possibility. With this in mind I look at sacred or liminal places within the landscape, as well as the idea of the sublime. I also consider the camera from this perspective, and finally present my own exhibition and body of work, reviewing it in the light of the narratives and themes explored through the thesis.

- Description: This mini-thesis investigates the concepts of refusal and rupture as a postdramatic revolt and how these terms can be applied and read within the context of analysing contemporary devised performance in South Africa. The argument focuses on the efficacy of Hans-Thies Lehmann’s postdramatic terminology and the potential of its use in an appreciation of contemporary performance analysis. I investigate the potential in South African contemporary devised performance practice to challenge prevailing modes of traditional dramatic expectation in order to restore the experience of discovery and questioning in the spectator. This research is approached through a qualitative process which entails a reading and application of selected critical texts to the analysis with an application of Lehmann’s terminology. This reading/application is engaged in a dialogue with the interpretative and experiential aspects of selected South African devised performances with particular focus on four cross-disciplinary works selected for analysis. Chapter One functions as an introduction to the concept of postdramatic theatre and the application of the terms refusal and rupture as deconstructive keywords in the process of a devised performance. Chapter Two is an analysis of several South African contemporary performances with particular focus on Body of Evidence (2009) by Siwela Sonke Dance Company, Wreckage (2011) a collaboration by Ubom! Eastern Cape Drama Company and First Physical Theatre Company, Discharge (2012) by First Physical Theatre Company, and Drifting (2013) by The Rhodes University Drama Department. This mini-thesis concludes with the idea that with an understanding of refusal and rupture in a postdramatic revolt, contemporary devised performance achieves an awakening in its spectators by deconstructing the expectation of understanding and the need for resolve; the assumption and need for traditional dramatic structures and rules are challenged. Instead, it awakes an experience of discovery and questioning.

- Description: Snappers of the genus Lutjanus are small to large predatory fishes occurring in inshore circumtropical and subtropical waters throughout the world. These fishes support fisheries across their distribution range. Within the Western Indian Ocean (WIO), previous studies on Lutjanus kasmira revealed limited spatial genetic differentiation, whereas Lutjanus fulviflamma showed high genetic connectivity. The phylogenetic relationships among WIO snappers are unknown. Previous studies in the Indo-Pacific (IP) did not include any WIO representatives. This study examined (1) the phylogeographic patterns in Lutjanus bohar, L. fulviflamma and L. lutjanus to understand the origins and factors influencing the distribution of diversity in the region, (2) how the physical environment, biological, and ecological factors influence genetic diversity, (3) the placement of WIO snappers in context to those from the IP, as well as the placement of taxa not included previously, (4) extent of differentiation among conspecifics from the two regions, and (5) the relationship of the Caesionidae to the Lutjanidae. Samples were sourced from across the WIO and from peripheral localities, where possible. DNA sequence data were generated from two mitochondrial gene regions (cyt-b and NADH-2) and a nuclear gene region (S7 intron 1). Data were analysed under a phylogeographic framework to examine genetic structure, diversity and differentiation among identified regions for each of the three species. Other sequence data were generated from two mitochondrial gene regions (COII and 16S rDNA) to examine the phylogenetic placement of WIO snappers in context of the IP snappers and the relationship of the Caesionidae to the Lutjanidae. Lutjanus bohar and L. fulviflamma displayed high genetic diversity, but lower diversities were observed for L. lutjanus. Genetic differentiation was observed between Mozambique and Maldives in L. bohar. Lutjanus fulviflamma was differentiated in South Africa, Mozambique, Mauritius and Thailand, while differentiation was observed between Kenya and Tanzania in Lutjanus lutjanus. Overall, low genetic differentiation and high connectivity were observed for each of the three species. This differentiation may result from intrinsic features of the species and extrinsic features of the environment, whereas the connectivity is mainly influenced by the pelagic larval duration. These patterns of differentiation are in accordance with a proposed vicariant biogeographic hypothesis for the origins of regional faunas of the IP. Phylogenies were similar to those published, with additional taxa not altering the previous groupings found. Conspecifics from the two regions clustered together, with varying degrees of differentiation among the WIO and IP, depending on the species. Members of the Caesionidae were nested within Lutjanidae, suggesting that morphological characters separating the two families are taxonomically insignificant. This affirms previous notions that the Caesionidae should be a subfamily within the Lutjanidae. This is the first multi-gene study, examining differentiation in multiple species of snapper over a wide geographic area in the WIO, and the results of this study could have potential implications for fisheries management and conservation.

- Description: Alteration index three (AI3), which calculates the balances between three microbially-secreted enzymes, potentially enables differences between soils due to contrasting management practices to be quantified in relative terms. The ability of AI3 to distinguish between apple orchard soils under conventional and organic production protocols, and to reflect tree performance, were tested in a maturing 'Cripps Pink'/M7 apple orchard. Activities of β-glucosidase, phosphatase and urease were determined colourimetrically in extracts of tree-row top-soils (0-15 cm) taken during September and January over five consecutive seasons. Soil organic matter content was determined by dichromate oxidation. Stem circumference and yield were measured manually. AI3 correlated significantly (p = 0.05) with soil organic matter, yield and yield efficiency. AI3 may thus be a useful indicator of relative apple tree performance under organic and conventional soil surface management practices.

- Description: Wild foods are an integral component of the household food basket, yet their quantified contribution to food security relative to other sources in the context of HIV/AIDS, climate change and variability remains underexplored. This study was carried out in Willowvale and Lesseyton which are rural communities in the Eastern Cape province of South Africa. Willowvale is a relatively remote, medium-rainfall coastal community, while Lesseyton is a peri-urban low rainfall inland community. Qualitative and quantitative methods were used to collect data from 78 HIV/AIDS afflicted households with 329 individuals and 87 non-afflicted households with 365 individuals in the two study sites. Households were visited quarterly over 12 months to assess food acquisition methods, dietary intake and quality, and levels of food security, and to determine strategies employed by households to cope with droughts. The wild foods investigated were wild meat, wild birds, wild fish, wild mushrooms, wild leafy vegetables and wild fruits. Diets were moderately well-balanced and limited in variety, with cereal items contributing 52 % to total calorie intake. Mid-upper arm circumference measurements showed that all respondents were adequately nourished. The bulk of the food consumed by households was purchased, with supplementation from own production, wild vegetables and wild fruits. In Willowvale, wild vegetables comprised 46 % of overall vegetable consumption for afflicted households and 32 % for non-afflicted households, while own fruit production comprised 100 % of fruit consumption. In Lesseyton, wild vegetables comprised only 6 % and 4 % of vegetable consumption for afflicted and non-afflicted households, while wild fruit comprised 63 % and 41 % for afflicted and non-afflicted households. More than 80 % of respondents from both afflicted and non-afflicted households had sufficient daily kilocalories, although the majority of afflicted households felt they were food insecure and sometimes collected wild foods as one of their multiple coping strategies. Hunting and gathering of wild foods was associated with site, household affliction status, gender, age and season. More than 80 % of respondents ate wild vegetables and said they were more drought tolerant than conventional vegetables, making them the most consumed wild food and approximately 16 % of respondents ate wild birds, making them the least consumed wild food. Approximately 14 % of respondents from afflicted households in Willowvale sold wild fish, whilst 34 % of respondents from afflicted households and 7 % from non-afflicted households sold wild fruits in Lesseyton. Strategies adopted by households to cope with droughts were different between the two study sites, and households in Willowvale used a wider range of strategies. Given the devastating effects of HIV/AIDS coupled with the drawbacks of climate change and variability on food security, wild foods represent a free and easy way for vulnerable households to obtain food.

However, little is known about the spatial and temporal scales of their habitat use and associated ecological role. In this study, we employed passive acoustic telemetry to investigate the residency patterns and migration dynamics of 18 adult bull sharks (195–283 cm total length) tagged in southern Mozambique for a period of between 10 and 22 months. The majority of sharks (n = 16) exhibited temporally and spatially variable residency patterns interspersed with migration events. Ten individuals undertook coastal migrations that ranged between 433 and 709 km (mean = 533 km) with eight of these sharks returning to the study site.

- Description: The most widespread intervention in South Africa into the sexualities of young people is school based sexuality education. However there is a dearth of research in this area, and studies that have been conducted highlight major weaknesses with implementation. Research from Western countries indicates that the messages conveyed in sexuality education are resisted if they conflict with the desired sexual subjectivities of young people. This indicates a need for further research into desired youth sexualities, and school based sexuality education. While South African studies of young people‘s talk about sexualities have been conducted, there is a paucity of literature in this area from a discursive perspective. This study is situated within a feminist post-structuralist paradigm, utilising a performative-performance analytical approach which synthesises Butlerian theory with a narrative-discursive methodology. This approach enables an analysis of both the macro-discursive power webs within which sexualities are situated, and the micro-discursive activity through which sexual subject positions are constructed. I used this approach to analyse the talk of groups of students from a Further Education and Training College about the sexualities of High School learners and their own past sexuality education. Findings showed that that the most dominant discursive resources which were utilised to construct sexualities were societal sexual norms discourses. These foundational discourses constructed gendered sexualities of compulsory hyper-heterosex for men, and compulsory compliant girlfriendhood for women. Such gendered sexualities reinforced patriarchal and abusive gendered and sexual practices. Ways in which participants troubled the dominant gendered sexualities through the performance of alternative sexual positions were analysed, as these 'troubling' performances indicate mutable aspects of the normative gendered field. Participants drew on a discourse of disconnect when talking about their school sexuality education, and their parents‘ (lack of) communication with them about sex. This suggests that adultist attempts to construct a 'responsible' sexual subject position for young people are resisted when such a position is constructed in a non-relational manner. Collusion between the constructed gendered sexualities and the discourse of disconnect results in the un-performability of a 'responsible' sexual subject position. These findings were used to provide suggestions for enhancing school based sexuality interventions.

- Description: That countries with high natural resource abundance should experience slower economic growth than those with low resource abundance seems contrary to what would be expected, considering the developmental head-start such resources afford. Yet Sachs and Warner (1997) found that economies with a high share of natural resource exports in national income in 1970 tended to experience slower economic growth in the two decades that followed. This finding, that natural resources are a “curse” rather than a blessing, has become generally accepted. This thesis sought to test whether the conclusion drawn from their data – that higher natural resource abundance leads to slower economic growth – is still correct. It sought to test their findings first by correcting for their use of resource intensity (natural resources share of exports) as a proxy for abundance. Using measures of resource abundance for 1995 as a proxy for abundance in previous decades, it was found that higher resource abundance was not associated with lower economic growth in the 1970s and 1980s. This finding is contrary to that of Sachs and Warner (1997, 2001). Secondly, this thesis tested whether the natural resource curse effect was still present for the period 1995–2010. This was done by observing the effect of both resource abundance and resource intensity on economic growth during 1995–2010. In both cases no resource curse effect was found, for this more recent period. The resource curse had disappeared regardless of whether one uses Sachs and Warner’s (1997, 2001) measure of resource intensity or a measure of resource abundance. Natural resources should therefore no longer be considered a “curse”. In explaining the difference for the impact of resource intensity between the 1970-90 period measured by Sachs and Warner (1997, 2001) and the more recent period 1995-2010 it was found that the Dutch Disease effect has decreased significantly since the 1970s and 1980s. This could partly explain why the resource curse has disappeared when measured in terms of resource intensity. Thus it was concluded that the natural resource curse existed in the period 1970-90 only when measured in terms of resource intensity but not when measured relative to resource abundance. The negative effects of natural resources on economic growth have disappeared in terms of both resource intensity and resource abundance in the more recent time period.
