- Description: African Cinema is an entity as diverse as the various countries, languages and cultures on this continent. The entertainment value of Cinema has been more popular than the study of its ideological significance, but nevertheless in a contemporary Africa where politics affect the social, cultural and economical survival of its citizens, Cinema can be used as a valuable asset and a powerful means of communication that can conscientize and educate African audiences. Thomas Hobbes’s leadership model and political theory of sovereignty, though a XVIIth century framework, can theoretically contribute in the analysis of the representation of African leadership styles in Cinema. This article analyzes four fiction films representing four different political leaders in, respectively, South Africa, Uganda, Cameroon and Nigeria. A film content analysis will explore the different representation of leadership styles, the personality of each leader, the power struggles in each society and how this may suggest value judgments about African leadership to the films’ various target audiences.

- Description: This thesis expands on primary field research conducted for my MMus degree. Undertaken in the Saharaui refugee camps of southern Algeria (2004-2005) that research - based on ethnographic data and the analysis of Saharaui music, known as Haul ¹- focussed on the musical system, the social context of musical performance and the music culture in Saharaui refugee camps. This doctoral research examines Saharaui Haul music as practised in Spain and is particularly focussed on its entry, since 1998, into the global market by way of the World Music label, Nubenegra records. The encounter between Saharaui musicians and Nubenegra records has created a new type of Saharaui Haul which is different to that played in the refugee camps. This phenomenon has emerged as a result of western music producers compelling Saharaui musicians to introduce musical changes so that both parties may be considered as musical agents occupying different positions on a continuum of tradition and change. Nubenegra undertook the commodification of Saharaui music and disseminated it from the camps to the rest of the world. A musical and social analysis of the relationship between Nubenegra and Saharaui musicians living in Spain will form the basis of the research in this thesis. In particular, Mariem Hassan is an example of a musician who had her music disseminated through the relationship with Nubenegra and she is promoted as the music ambassador of the Western Sahara. I collaborated with her as a composer and performer on her last album, El Aaiun egdat (Aaiun in fire), in 2012² and gained first hand insight into the relationship between Mariem and Nubenegra. This thesis reflects on this relationship and my role in facilitating this encounter.

- Description: The new curriculum in Namibia has introduced a new approach to teaching and learning requiring teachers to make use of learners’ prior everyday knowledge (PEK) including indigenous knowledge (IK) and practical work/activities. It further emphasizes some variations in teaching methods such as; the use of analogies, the use of mind maps, and so forth with the aim to actively involve learners in the learning process and develop skills to solve global challenges. The emphasis is on understanding of knowledge, skills and the will to use them appropriately throughout their lives. The main aim of this study was to understand and document how Biology teachers mediate learning of the topic respiration. Informed by an interpretive paradigm, a qualitative case study was conducted at two secondary schools in the Kunene region. The participants were selected using a convenience sampling. Data were gathered using three main sources, namely, documents, semi-structured interview questions which culminated into a questionnaire and observations. Triangulation was thus used to give credibility, objectivity and validity to the interpretation of the data. Data analysis in this case study involved a multi-stage process of organizing, coding and categorizing, synthesizing and summarizing. The audio recorded lessons were transcribed into text and I analyzed data using a colour coding technique by segmenting and labelling text to identify descriptions and broad themes in the data. Vygotsky’s Mediation of Learning and Social Constructivism in conjunction with Shulman’s Pedagogical Content Knowledge (PCK) informed the data analysis process. Teacher-learner interactions were the main theme for mediation of learning (social constructivist perspective), hence during analysis I paid more attention to moments where interactions evolved and I used PCK to gain insights in teaching and instructional strategies used by teachers. The findings of this study revealed that: 1) teachers endeavor to use a variety of teaching methods such as the use of a mind maps and question and answer method. Learners were keen to ask questions in order to understand this topic. 2) The study also revealed that a lack of practical activities is one of the challenges teachers are faced with. Based on my research findings, I therefore suggest that there is a need for continuous professional development of biology teachers and capacity building in order to improve both their content and pedagogical content knowledge.

- Description: This study emerged in response to the poor performance in Biology at my school. The Ministry of Education Biology (NSSCO) Examiners’ report (2011) for Paper 3 indicates that learners proved to have difficulties in designing experiments, failed to give a distinction between apparatus and the experiment. The 2012 Examiners’ report on transpiration also highlights that learners were not exposed to practical work. Furthermore, the 2012 report notes that teachers need to work on their learners’ drawing and spelling of terms. It is against this backdrop that a qualitative study was conducted at a school in Oshikoto, using a sample of two teachers. The study’s purpose was to investigate how grade 11 Biology teachers mediate learning of the topic on transpiration. Social Constructivism and Pedagogical Content Knowledge formed the framework used to analyse data gathered from document analysis, interviews and observations. The study findings were that teachers use locally available material for demonstration during practical work, elicit prior knowledge, use a chalkboard to summarise content to learners, and use a question and answer method as strategies in mediating learning on transpiration. In addition, the teachers use homework, scaffolding activities, group work, code-switching, feedback on activities, as well as the use of analogies. Despite efforts by participant teachers to mediate learning of transpiration, shortage of equipment for conducting practical work, poor English proficiency among teachers and learners, and little emphasis on graphing by the syllabus proved to be barriers to their efforts. This study thus recommends that in order to improve on teaching transpiration, teachers need to co-plan lessons, conduct practical work, code-switch during lessons, ensure effective assessment, and include lessons on graphing. Furthermore, teachers need continued training on how to teach transpiration.

- Description: This research focused on an investigation of the pedagogy and strategies used by Grade 11 Life Sciences teachers when mediating Biodiversity concepts with English second language learners. My interest in this investigation was triggered by the Examiners’ Reports for Life Sciences from 2009 to 2012 which consistently noted learner challenges in answering, interpreting and analysing questions during exams. The reports highlighted learners’ lack of understanding of the questions which led to them providing irrelevant information in their exam scripts. These reports claimed that challenges experienced by these learners could be attributed to language issues experienced by English second language learners. Influenced by these reports, a qualitative case study of two Senior Secondary schools in East London, Eastern Cape South Africa was conducted. Underpinned by an interpretive paradigm and driven by the desire to achieve an in-depth understanding of the case under study, three phases of information gathering were followed. The first phase was that of gathering information through document analysis. Documents were analysed to gain insights and understanding of the issue before conducting interviews. The next phase was that of gathering information through semi-structured interviews followed by classroom observations. Findings from these observations were verified through stimulated recall interviews which provided clarity on the intentionality of choosing a certain method and strategy over another when assisting learners in making meaning of biodiversity concepts. The main findings of this study are that factors which limit learner understanding of biodiversity concepts are a result of a combination of factors such as failure to interpret questions, spelling problems which alter meaning of concepts and an inability to make distinctions among closely related concepts within the topic of Biodiversity. Responding to these factors, teachers demonstrated knowledge of a variety of teaching strategies to support learners. The choice of teaching strategies seemed to be guided by their experiences as well as the challenges they often encounter. Furthermore, teachers’ reflections on their practice provided opportunities for them to identify strengths and limitations of their choice of strategies and possibilities for improvement. It was also noted that factors such as large class sizes, gaps in content knowledge and a lack of detail in chalkboard summary limited the effectiveness of their teaching strategies. The study recommends that: • Teacher-learner ratio needs to be considered for effective support; • There is still a need to capacitate educators in environmental education. In-service training should focus on developing teacher understanding of foundational knowledge in life sciences; and • Teachers need to improve their chalkboard summary skills to increase the level of support that could be provided by comprehensive chalkboard summary through the elaboration of ideas

- Description: The National Curriculum of Education was implemented with the broad view of including all learners as laid out in the document Toward Education for All. The curriculum emphasised that the topic distillation should be studied. According to the Examiners Reports, the topic distillation is one of the topics where learners face difficulties in the Namibian Senior Secondary Certificate Ordinary (NSSCO) examination Grade 12. This led me to do research on understanding how Physical Science teachers mediate the topic distillation in Namibia specifically in the Kavango region. The study was carried out at two rural schools with two teachers teaching Grade 11. The community member who I asked to demonstrate the making of Kashipembe was also a participant during this study. Kashipembe is a local cultural brew alcohol beverage commonly made in the Kavango East and West Regions of Namibia, which was used as a learning context in this research study. The study used a qualitative case study underpinned by an interpretive paradigm. Data was generated through the use of document analysis, semi-structured interviews, stimulated recall interviews, lesson observations, brainstorming and practical demonstration of making Kashipembe. These different methods of data gathering were used with the aim of triangulating and validating the data. Therefore, my theoretical framework adopted Vygotsky’s (1986) mediation of learning, social constructivism and pedagogical content knowledge according to Shulman’s (1986) theory. The emergent themes were identified inductively and they were colour coded. These themes were later developed into analytic statements which were used in the study. The findings indicate that the use of community knowledge and experience during the teaching of scientific concepts like distillation is important. These findings can also be used by the practising teachers to make their teaching more effective in the curriculums where distillation is included. Therefore, the Namibian curriculum developers need to include this community knowledge in the curriculum to make it easier for the learners to make sense of the topic distillation.

Whither South Africa – neoliberalism or an embodied communitarian indigenous ethic?

- Description: This thesis offers a critique of neoliberal transformation in South Africa, which process results in growing social inequality and political apathy among citizens. Many scholars have made political-economic and historical analyses of the neoliberal transition, emphasizing structural changes at work at a ‘macro’ level. However, little attention has been paid to changes that have taken place in South Africa at the ‘micro’ level – changes to individual subjectivity and gender codes. That said, the thesis opens by summarizing the above mentioned political-economic accounts of neoliberalism in South Africa, because such works are indispensable to understanding how the regime is embedded within and buttressed by major global institutions. Yet, to achieve a holistic grasp of ‘neoliberal South Africa,’ more is needed. A sociological investigation into the impact of neoliberalism on ordinary people’s self-identification uncovers deep cultural reasons for the continued perpetuation of this unjust political-economic system. Only if it can be understood why people comply with the system in the face of suffering, can effective counter-measures be proposed and implemented over time. This thesis is inherently transdisciplinary. The approach rejects the privileging of one discipline over others, and likewise cautions against collapsing or dissolving disciplines into one another. Instead, recognizing the valuable contribution that each discipline can make to critical scrutiny of a particular issue, a form of methodological transversalism is used to bring different disciplines into dialogue with one another. Following this interplay of structural and subjective analysis, the thesis uncovers the role that consumerism plays in the political neutralization of South Africans. Consumer culture, tied as it is to profitable accumulation, instigates the neoliberal ‘values’ of economistic calculation, competition, and social atomization. This ethos is inculcated in individuals, both at work and during leisure hours. Moreover, consumerism derives much of its power from its ‘sexual sell,’ the creation of fashionable and ‘exemplary’ models of masculinity and femininity. In South Africa, these hegemonic gender models serve to instill competitive individualism while derogating indigenous values. The thesis proposes that in order to counter neoliberal hegemony in South Africa, and begin reclaiming the cultural autonomy of its peoples, it is important to invigorate indigenous communitarian practices and norms. The original contribution of this thesis consists in placing the African ethos of ubuntu in transversal dialogue with global ecological feminist voices. Both political perspectives reinforce a liberatory alternative vision for a future based on principles of embodied relationality, care giving and protection of community.

- Description: The study sought to examine human resource management strategies and their contributions to effective local government systems in Manicaland, Zimbabwe. Local government in Zimbabwe, though being nearest to the people, is showing evidence of failure to discharge its mandate. Various factors have been used to explain the reasons behind local government‘s failures to provide services. None of these have touched on the role played by people management in ensuring local government performance. This was notwithstanding the fact that towards the last two decades of the twentieth century research emerged glorifying human resources as the source of organizational excellence. Consequently, being motivated by the fact that good people management strategies lead to excellent organizational performance, attention in this study focused on people management strategies in local government in Zimbabwe. The study adopted a mixed approach with a strong inclination towards qualitative methodology. The data was gleaned from documents from local authorities, interviews, focus group interviews and questionnaire surveys. The study focused on local authorities in Manicaland Province. The results of the study confirmed the existence of human resource management strategies in local authorities in Manicaland, Zimbabwe. The human resource management strategies have however not resulted in excellent performance of local authorities. The reason behind this is attributable to severe resource constraints.

- Description: The study sought to examine human resource management strategies and their contributions to effective local government systems in Manicaland, Zimbabwe. Local government in Zimbabwe, though being nearest to the people, is showing evidence of failure to discharge its mandate. Various factors have been used to explain the reasons behind local government‘s failures to provide services. None of these have touched on the role played by people management in ensuring local government performance. This was notwithstanding the fact that towards the last two decades of the twentieth century research emerged glorifying human resources as the source of organizational excellence. Consequently, being motivated by the fact that good people management strategies lead to excellent organizational performance, attention in this study focused on people management strategies in local government in Zimbabwe. The study adopted a mixed approach with a strong inclination towards qualitative methodology. The data was gleaned from documents from local authorities, interviews, focus group interviews and questionnaire surveys. The study focused on local authorities in Manicaland Province. The results of the study confirmed the existence of human resource management strategies in local authorities in Manicaland, Zimbabwe. The human resource management strategies have however not resulted in excellent performance of local authorities. The reason behind this is attributable to severe resource constraints. Excellent people management strategies were found to be on paper as there were no resources to support them. The dearth of resources in local authorities was found to be attributed to the economic, political, legal and social factors engulfing the local government system in Zimbabwe. Consequently, local government in Zimbabwe remain stressed and in dire need of a ―Lazarus moment‖.

- Description: This study investigates teachers‘ experiences on English as the language of learning and teaching of isiXhosa learners. It critically examines the teachers‘ practices and experiences towards English as the sole language of learning and teaching LOLT at two different primary schools in Ncerha in the East London District in the Eastern Cape. The study is guided by the fact that most learners use their mother tongue isiXhosa in classroom as well as outside classroom contexts. Furthermore, some teachers use the translation method as they code-switch to their home language when teaching content subjects as well as English but learners are expected to answer the test and examination questions in English Maphalala 1988.Theoretically, this study is underpinned by the constructivist view of language learning Gaserfeld 2003 and English as an international language Sivasubramaniam, 2011. On the basis of the ecological and the constructivist approaches to language learning, Sivasubramaniam 2011 p53 views language as a creative instrument of meaning which has the power to create meaning anew and afresh‘ each time that someone uses it. The study makes use of the qualitative research method with a case study design. The data collected was analysed within the framework of discourse analysis.The findings of this study suggest some instrumental motivations for the use of English as LOLT. Some of these motivations are studying abroad, business with foreign investors Abongdia, 2009 and integrative motivations as the learner might be able to communicate with people from different countries Lambert and Gardner, 1972 Baker 2006 and Abongdia 2009. , Thesis (MEd) -- Faculty of Education, 2015

- Description: The 1996 Constitution of South Africa is ranked as one of the most liberal and democratic constitutions in the world. The right to freedom of sexual orientation, equality and the freedom of association amongst other rights is in its Bill of Rights and are thus inherently assured and protected in post- apartheid, democratic South Africa. However, the Lesbian Gay Bisexual and Transgender (LGBT) community continue to face discrimination and prejudice despite this newly established constitutional order. The present study is interested in how, in the light of the equality clause in the South African constitution, homosexuality is represented and constructed in the South African media. The thesis examines representations of homosexuality between the years 1999-2013 in articles collected from the Independent Online media site which incorporates 30 newspapers. The approach focuses on the topics, overall news report schemata, local meanings, style and rhetoric of the news reports. The results of the study show that negative attitudes towards homosexuality are framed in three main ways: homosexuality is represented as "unAfrican"; "ungodly" and "unnatural". I argue that rather than extreme forms of violence (such as "corrective rape" and murder) directed against LGBT citizens being interpreted as the aberrant behaviour of a few, these need to be understood in the context of the circulation of the above justificatory narratives.

- Description: Deon van der Walt was, at the height of his career, considered the leading lyric tenor of his generation. In a career that spanned more than 25 years he performed in the great opera houses of the world and sang for the leading conductors of the time, sharing the stage with the best singers in the world. He was the first male South African to accomplish the so-called “grand slam” of opera, having sung in the Royal Opera House, Covent Garden (London), Wiener Staatsoper (Vienna), La Scala (Milan) and the Metropolitan Opera House (New York). He was also a prolific oratorio and lieder singer, collaborating with the best artists the musical world had to offer. In addition he left a large recorded legacy, both published and unpublished. His untimely death on 29 November 2005 was extensively reported on both locally and abroad - a fact which again highlighted the importance of his personal and professional contribution to the international opera world.The Deon van der Walt Collection is the single most important key to unlocking the life and career of one of the most successful South African opera singers of all time. It was bequeathed to the Nelson Mandela Metropolitan University (NMMU) Library the Deon van der Walt Trust in 2007. The collection is made up of an arbitrary assortment of books, documents, sound and video recordings that were left in van der Walt’s Zürich accommodations at the time of his death in 2005. It is housed in separate section on the lower level of the South Campus Library of the NMMU. The collection has been partially catalogued by the NMMU Library but left largely unattended for the last 6 years. The compiling of an annotated catalogue of this collection is the vital first step in connecting the dots of an extraordinary musical career that was hailed as one of the greatest of his time.

- Description: In this study I focus on a number of collections of short fiction by the South African writers Joël Matlou, Sindiwe Magona, Zoë Wicomb and Ivan Vladislavić, all of which evince certain of the characteristics of short story cycles or sequences. In other words, they display what Forrest L. Ingram describes as “a double tendency of asserting the individuality of [their] components on the one hand and of highlighting, on the other, the bonds of unity which make the many into a single whole”. The cycle form, thus defined, is characterised by a paradoxical yet productive and frequently unresolved tension between “the individuality of each of the stories and the necessities of the larger unit”, between “the one and the many”, and between cohesion and fragmentation. It is this “dynamic structure of connection and disconnection” which singularly equips the genre to represent the interrelationship of singular and collective identities, or the “coherent multiplicity of community”. Ingram, for example, asserts that “Numerous and varied connective strands draw the co-protagonists of any story cycle into a single community. … However this community may be achieved, it usually can be said to constitute the central character of a cycle”. Not unsurprisingly, then, in its dominant manifestations over much of the twentieth century the short story cycle demonstrated a marked inclination towards regionalism and the depiction of localised enclaves, and this tendency towards “place-based short story cycles” in which topographical unity is a conspicuous feature was as pronounced in South Africa as elsewhere. However, the specific collections which are my concern here increasingly employ innovative and self-reflexive narrative strategies that unsettle generic expectations and interrogate the notions of regionalism and community conventionally associated with the short story cycle. My investigation seeks to explain this shift in emphasis, and its particular significance within the South African context.

- Description: This treatise is a qualitative study that critically explores a current body of knowledge significant to the development of the female adolescent voice. The female adolescent voice is a field that is relatively under-researched in comparison to the male adolescent voice, although research in this regard has shown an increase in interest in the last two decades (Gackle 2011: 11). However, information related to the male adolescent voice still far outweighs the female adolescent voice. This study, through the use of six secondary objectives, identifies and highlights areas of the female adolescent voice development, where much of the current research lacks depth and insight. It therefore analyses and compares applicable literature in an attempt principally to contribute to a more structured and academic approach in this field. Insight into the auditory effects that occur during physiological mutation is further supported by investigating the functioning of the female voice registers and the respective influences of these on the different phases of vocal development of the female adolescent. The assistance and expertise of the conductor in this process, as well as in common areas such as voice classification, auditioning, voice placement, and repertoire selection are investigated to further consolidate and compare possible interventions for problems pertaining specifically to the female adolescent voice. The study concludes with a summary of the treatise and proposes suggestions for further study in this field.

- Description: This project asserts that revolution is characterised by the expression of unthinkable possibilities, and so addresses the paradox implicit in any attempt to "write revolution." That is, how does one represent revolution without reducing it to an ordered term of reference, and thereby subduing its radical character? Additionally, can transformative action be conceptualised as a creative project to which an ethical subject may, and in fact should, be drawn? To answer these questions, my investigation develops in three strands. I combine the radical theory of Alain Badiou with similar affirmations of revolutionary intervention from Slavoj Žižek and Paulo Freire, and so create an aesthetic that affirms revolutionaries as agents of supplementary creativity. My first purpose is thus to establish revolution as a productive enterprise that enables peace, rather than a destructive undertaking that introduces violence. This done, I apply the resultant conceptual tools to literary representations of radical transformation, and demonstrate that my aesthetic enables new readings of the literature of revolution to which it is applied. In the course of my analysis, I also evaluate the suitability of Badiou's ethic as a standpoint from which to engage with literature on revolution. Ultimately, then, the aesthetic I construct not only contests the notion that radical transformation is always destructive, but also renders one sensitive to revolutionary literature's excessive and supplementary dimensions.

In particular, it is concerned with the representation of Johannesburg, and specifically Hillbrow, in relation to the space of the rural, the suburban enclave and the city of Cape Town. I argue that while so-called urban ‘slums’ such as Hillbrow have been denigrated in the local imaginary, the texts that I have selected draw attention to the potentialities of such spaces. Rather than aspiring to ‘First World’ aesthetics of modernity then, we might come to see such spaces as Hillbrow anew, and even to learn from them as models, so as to better create more fully integrated and dynamic African cities.

- Description: This qualitative case study was undertaken in order to explore the experiences of drum set students who apply themselves to James Dreier’s Standard Tune Learning Sequence (STLS) in a self-directed learning environment. These experiences ultimately shed light on how best to implement Differentiated Instruction to the STLS. The study draws on the experience of three adult drum students under the instruction of the author. The students were provided with the STLS and left to proceed with it on their own. They were asked to keep a record of their progress in the form of a learning journal. These learning journals were used, in conjunction with transcribed interviews and learner profiles, as data for this study and as such were subjected to Interpretative Phenomenological Analysis. The study recognizes three factors which affect the student’s successful progression through the STLS: readiness, interest and meaning. Each factor is discussed in relation to literature on differentiated Instruction. Recommendations are made regarding the implementation of Differentiated Instruction to the STLS.

- Description: This thesis reports on a multiple case study PhD project that aimed to investigate meaningful and critical development of knowledge and strategies to teach visual literacy, a component of English First Additional Language (FAL) in six under-resourced schools of the Eastern Cape of South Africa. The study begins by locating visual literacy within a broad framework of literacy as a social practice, and discusses its importance. Further, it discusses complexities of making sense of and teaching visual literacy, especially for the majority of in-service teachers who experienced visual literacy neither as learners nor as teacher trainees. The gap between the curriculum and teachers’ classroom practices is what triggered this study to adopt a transformative paradigm. The main research question is, “How can teacher professional development in English Language Teaching advance in-service teachers’ knowledge of and strategies for meaningful and critical teaching and learning of visual literacy?” To respond to this question, I drew on cultural historical activity theory (CHAT) and critical realism (CR) to design four phases of this study that incorporated the seven stages of an expansive learning cycle. These phases focussed on exploring and expanding teachers’ sense making and teaching of visual literacy. I collected data through interviews, document analysis, videoed lessons and change laboratory (CL) workshops. I designed a data analysis tool that brought together CHAT, CR, multimodal social semiotics, critical discourse analysis and pedagogical discourse to make sense of the data. Through a process of reflexivity, the study illuminated layers of factors that constrained meaningful and critical teaching of visual literacy in the empirical, the actual and the real domains of reality. These factors include teachers’ unconscious reproduction of discourses of domination, their intolerance of diverse cultural discourses, resistance to curriculum change, and the fact that they are comfortable with the status quo. I brought these factors to CL workshops for expansive learning. The study contributes in-depth insight into English FAL in-service teacher development in the area of visual literacy. By locating the study within meaning making and teaching of visual literacy, it was possible to interrogate access, diversity, domination and design in teachers’ classroom practices. As a result of this study participants were made aware of the extent to which these factors enabled or hindered meaningful and critical teaching. Participants repositioned themselves as subjects of the activity system, thereby mobilising their agency to take control of the structures and cultures that condition their teaching.

- Description: The central argument of this thesis asserts that in the process of challenging dominant subject positions, such as whiteness, performance creates the possibilities for new or alternative arrangements of desire. It examines how the creative process of desire is forestalled (reified) by habitual representations of whiteness as a privileged position, and proposes that performance can be a valid form of resistance to static conceptions of race and subjectivity. The discussion takes into account how the privilege of whiteness finds representation through forms of neo-liberalism and neo-colonialism in the post apartheid context. The analysis focuses on the work of white South African artists whose work offers a critique from within the privileged “centre” of whiteness. The research is situated within the inter-disciplinary field of performance studies entailing a reading and application of critical texts to the analysis. Alongside this qualitative methodology surfaces a subjective dialogue with the information presented on whiteness. Part Two includes an analysis of Steven Cohen’s The Cradle of Humankind (2011), Brett Bailey’s Exhibit A (2011) and Michael MacGarry’s LHR-JNB (2010). Each section examines the way in which the respective works engage in a questioning of whiteness through performance. Part Three investigates South African rap-rave duo, Die Antwoord and how their appropriation of Zef interrogates desires for an essential authenticity. Part Four focuses on my own performance practice and the proposed value of engaging with a form of practice-led research. This is particularly relevant in relation to critical race studies that require a level of self-reflexivity from the researcher. It presents an analysis of the work entitled Villain (2012) as a disturbance of theatrical desire through a process of ‘becoming’. This notion of meaning and identity as ‘becoming’ is argued as a strategy to challenge prevailing modes of perception which can possibly restore the production of desire to the viewer. The thesis concludes with the notion that performance can offer a mode of immanent ethics which is significant in creating both vulnerable and critical forms of whiteness.

- Description: This study is an initial attempt to identify the most common Afrikaans diction challenges experienced by non-Afrikaans mother tongue speaking choirs, and to explore means of confronting these challenges. No dedicated source exists for choral diction in Afrikaans as a foreign language. This study reviews personal views and literature from various fields that would inform several key elements necessary for the creation of such a source. The primary data for this study was collected through study questionnaires, completed by expert choral conductors who are highly regarded for their success in teaching and performing Afrikaans diction in non-Afrikaans mother tongue speaking choirs, in performance settings such as the ATKV-Applous Choir Competition. Through its proposition of methods for the improvement of Afrikaans diction practices in the non-Afrikaans choral setting, the study promotes the prolific composition of Afrikaans choral literature, and its ubiquitous inclusion in choral repertoire both in South Africa and abroad.

- Description:
Stavudine (D4T) has been used as first line treatment for HIV/AIDS and is part of highly active anti retroviral treatment (HAART). It is an affordable medicine and its use is beneficial in resource limited settings. However D4T exhibits dose dependent side effects that may lead to non-adherence in patients. This study was undertaken to formulate, develop and manufacture a dosage form that could reduce dose dependent side effects by decreasing the dose of D4T but still exhibit antiretroviral (ARV) activity. The use of sustained release (SR) formulations of D4T that ensure constant levels of the D4T in the body would not only optimize therapy but also reduce the incidence of side effects thereby increasing patient adherence. SR microparticles containing 30mg D4T were manufactured and loaded into size 3 hard gelatine capsules prior to analysis. The D4T microparticles were manufactured by microencapsulation using non-aqueous oil-in-oil solvent evaporation approach. D4T-excipient, excipient-excipient interactions and D4T purity were assessed using Infrared Spectroscopy (IR), Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA). Copolymers synthesized from acrylic and methacrylic acid esters viz., Eudragit® RSPO and S100 were used as rate retardant materials and the effect of microcrystalline cellulose (Avicel® PH102) on the microparticles was also investigated. Magnesium stearate was used as a droplet stabilizer and n-hexane was added to harden the microspheres formed in a liquid paraffin continuous phase. The microparticles were optimized using a Box Behnken design and Response Surface Methodology (RSM). The microparticles were characterized in terms of their flow properties and encapsulation efficiency (% EE), in addition to visualization of the surface morphology with Scanning Electron Microscopy. In vitro D4T release studies were performed using USP Apparatus III in media of different pH and the samples were analysed using a validated High Performance Liquid Chromatographic (HPLC) method with ultraviolet (UV) detection that had been developed and optimized using a Central Composite Design (CCD). The method was validated according to ICH guidelines. The IR spectra and DSC thermographs revealed that D4T exhibited thermal stability and there was no evidence of D4T-excipient and excipient-excipient interactions. The microparticles that were produced were white, free flowing and were obtained in a high yield with high encapsulation efficiency. Scanning Electron Microscopy studies revealed that the microparticles were spherical and porous in nature. In vitro D4T release extended to 12 hours and the mechanism of release was established using model dependent methods by fitting the data to a Zero order, First order, Higuchi and Hixson Crowell model. It was observed that the mechanism of D4T release was diffusion-controlled and that the data was best fitted to the Higuchi model with correlation coefficients > 0.9. The release mechanism was confirmed using the Korsmeyer-Peppas model that revealed that most of the formulations exhibited anomalous transport kinetics with the release exponent, n, ranging from 0.5
