- Description: There appears to be a growing body of literature focusing on PTSD and HIV-related PTSD (the diagnosis of HIV being the significant traumatic event) amongst HIV-positive samples, but only a few African studies that attempt to estimate the prevalence of PTSD amongst HIV-positive people, and even fewer that attempt to estimate the prevalence of HIV-related PTSD. The systemic review presented in this study is currently fully inclusive and is the most up-to-date available. Estimates of the prevalence of PTSD and HIV-related PTSD in South Africa range from 0.7 to 54.1% and, 4.2 to 40% respectively. The current cross-sectional study made use of a mixed-method approach to investigate traumatic life events, PTSD and HIV-related PTSD within a primary health-care centre in KwaZulu-Natal. The quantitative sample consisted of 159 adults (18-50 years) who were compliant on ARV medication. Using the CIDI-PTSD module, the adapted CIDI-PTSD module for HIV, and IES-R, findings indicated that 62% had reported some kind of traumatic event in their lifetime, with 29.6% of participants meeting the criteria for lifetime PTSD, and 40.9% meeting the criteria for lifetime HIV-related PTSD. Altogether, 57.9% of individuals met the criteria for some form of PTSD (either regular PTSD or HIV-related PTSD), and 12.6% met the criteria for both PTSD and HIV-related PTSD. Of the different categories of traumatic events, interpersonal violence has the highest rate of PTSD, followed by a diagnosis of and living with HIV, and then disaster. Furthermore, the IES-R was compared for its usefulness as a screening measure for PTSD against both the CIDI, but results suggest that it is an inferior screening measure to the PDS. The qualitative study consisted of six participants who were examined using IPA methodology informed by the Ehlers and Clark (2000) Model of trauma. Their experiences revealed experiences of stigma, a number of negative appraisals, negative emotions and coping behaviours. Some of the latter might serve as compensatory mechanisms to avoid negative judgements. Hypervigilance seems to be a feature of ARV-compliance that might confer added vulnerability to PTSD and other anxiety disorders.

"To learn how to speak": a study of Jeremy Cronin's poetry

- Description: In the chapters that follow, the porous boundary between the public and the private in Jeremy Cronin’s poetry is investigated in his three collections, Inside (1983), Even the Dead: Poems, Parables and a Jeremiad (1996) and More Than a Casual Contact (2006). I argue two particular Marxist theorists are central to reading Cronin’s poetry: Bertolt Brecht, and his notion of the Verfremdungseffekt, and Walter Benjamin and his work on historical materialism, primarily the essay On the Concept of History / Theses on the Philosophy of History (1940). Both theorists focus on the work of art in a historically contextualized manner, which extends the challenge to the boundary between the public and the private. Their work is underpinned by the desire to draw out hidden narratives occluded under the grand narratives of history and capitalist ideas of progress. I argue that these are the major preoccupations in Cronin’s oeuvre as well. As such Cronin’s poetry may be seen to write against a perspective that proposes a linear conceptualisation of history. The poetry therefore challenges the notion that art speaks of ‘universal truths.’ Such ideas of History and Truth, if viewed uncritically, allow for a tendency to conceive of the past as unchanging, which subconsciously promotes the idea that social and political realities are merely logical evolutionary steps. I argue that Cronin’s poetry is thus purposefully interruptive in the way that it confronts the damaging consequences of the linear conceptualisation of history and the universal truth it promotes. His work attempts to find new ways of connection and expression through learning from South Africa’s violent past. The significance of understanding each other and the historical environment as opposed to imposing perspectives that underwrite the symbolic order requires the transformation rather than the simple transferral of power, and is a central focus throughout Cronin’s oeuvre. This position suggests that while the struggle for political freedom may be over, the necessity to rethink how South Africans relate to each other is only beginning. Chapter One will focus on positioning Cronin, the poet and public figure, in South African literature and literary criticism. In this regard, two general trends have operated as critical paradigms in the study of South African poetry, namely Formalism (or ‘prac crit’) and a Marxist inflected materialism, which have in many ways perpetuated the division between the private and the public. This has resulted in poetry being read with an exclusive focus on either one of these two aspects, overlooking the possibilities of dialogue that may take place between them. Cronin’s perspective on these polarised responses will be discussed, which will illustrate the similarity of his position to Ndebele’s notion of the ‘ordinary’ which suggests a way beyond these binaries. This will lead to a discussion of how South African poets responded to the transition phase, suggesting that the elements of the polarisation still remained. Considering the major influences and paradigms when reading Cronin’s oeuvre provides a foundation for the following three chapters. These include Cronin’s use of Romanticism, Bertolt Brecht and the V-Effekt and Walter Benjamin’s perspectives on historical materialism. In addition to these three theoretical paradigms, the relevance of Pablo Neruda’s poetry to Cronin’s work is also foregrounded. In Chapter Two, the focus will be on Cronin’s first collection of poetry, Inside, concentrating on Cronin’s use of language as a way of constructing poetry in the sparseness of the prison experience. This will show an abiding preoccupation of learning to speak in a language that considers the material context out of which it emerges. In this regard, the poems “Poem-Shrike” “Prologue” and “Cave-site” are analysed. In addition, one of the central poems in Cronin’s oeuvre, “To learn how to speak […],” will be examined in order to illustrate how the poet extends this project on a meta-poetic level, asking for South African poets to ‘learn how to speak’ in the voices of South African experience and histories. I will show how this is linked to Cronin’s “Walking on Air” which illustrates how the V-Effeckt recovers the small private histories through re-telling the life story of James Matthews, a fellow prisoner incarcerated for his anti-apartheid activism, revealing how this story is intimately connected to the public sphere. In Chapter Three, Cronin’s second collection: Even the Dead: Poems, Parables and a Jeremiad will be examined. In the poem “Three Reasons for a Mixed, Umrabulo, Round-the-Corner Poetry” Cronin resists inherited Western poetic conventions by incorporating and subverting versions of the Romantic aesthetic, arguing for poetry to be immersed in South African multi-lingual and multi-cultural experiences. “Even the Dead” reveals how Cronin uses Walter Benjamin’s perspectives on historical materialism to confront amnesia. In terms of the themes established in “To learn how to speak […]”, the poem “Moorage” demonstrates how the public and private can never be separated in Cronin’s work. The final section of this chapter will examine how Cronin responds to Pablo Neruda’s poems “I am explaining a few things” and “The Education of a Chieftain,” and how these poems challenge narratives that privilege the ‘great leader’ instead of the so-called smaller individuals’ stories. Chapter Four examines selections from Cronin’s third collection, focusing on Cronin’s use of the automobile, charting an ambiguous trajectory through the ‘new’ South Africa. The examination of the poems “Where to begin?”, “Switchback” and “End of the century - which is why wipers,” all attempt to include individuals left on the margins of the narrative of global freeways and neo-liberal capitalist progress. The poems present an interrogation of how ‘vision’ is constructed. This will show that the poetry responds to the experiences of the marginalised under these grand narratives in a primarily fragmentary and interruptive manner. This in effect constitutes the culmination of Cronin’s poetic journey and the search for new ways of envisaging South Africa’s future and finding a new language with which to speak it.

- 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: At present the Swedish points system is one of the main determinants of an applicant either being granted or refused entry into many South African higher education institutions (HEIs). Using a grounded theory approach, this article interprets the experiences of participants whose school performance and therefore university 'entry points' were lower than the expected norm. Despite not meeting standard university entry requirements, these students succeeded at university, completing their degrees in the minimum time available and going on to higher degrees. The journey of these participants - from low entry points to academic success - suggests that points based on school performance are not necessarily the best way of identifying students' potential to succeed in the contemporary South African educational context. If their entry points were not a good indication of their ability to thrive at university, the article asks, what is it about these participants that accounts for their success? And what implications does this have for South African practice, not only with regard to admissions policies but also in relation to the responsibilities of HEIs to students once they are admitted?

- Description: Gibson Ncube’s ‘Sexual/Textual Politics: Rethinking gender and sexuality in gay Moroccan literature’ focuses on an emerging body of gay literature that is developing within the larger framework of Moroccan literature. Ncube attempts to illustrate how the contemporary narratives of Rachid O. and Abdellah Taïa portray the quotidian experiences of minority sexualities who strive to exist in the hegemonic heteropatriarchies of Moroccan societies. These narratives challenge and destabilise the heteronormative ideals of Arab-Muslim communities and endeavour to offer alternative ways of thinking about marginalised sexualities in the public space. This analysis draws on the feminist underpinnings of Maria Pia Lara to argue that private gay narratives have the potential to re-imagine the public domain.

- 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.

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: In South Africa, the quality of health care is directly related to the concept of patient-centred care and the enactment of the Batho Pele Principles and the Patients’ Rights Charter. The quality of health care delivery has dropped drastically, and reports in the media indicate that public hospitals in the Eastern Cape Province are on the brink of collapse, with thousands of patients being treated in condemned hospitals. Receiving and rendering health care in the face of such challenges, the question arose: “Are patients receiving patient-centred care in public hospitals?” The answer to this rhetorical inquiry appeared to be obvious, but this research study explored and described professional nurses’ perceptions of patient-centred care in public hospitals and their understanding of evidence-based practice and best practice guidelines. The proposed study followed a qualitative, exploratory, descriptive and contextual design. The research population included professional nurses who are employed in public hospitals in Nelson Mandela Bay, and consisted of nurse managers and nurses who work in the wards. The research study consisted of three phases. In Phase 1, semi-structured interviews and focus groups were conducted with nurse managers and professional nurses working in the wards in order to collect data about their perceptions of patient-centred care and their understanding of evidence-based practice and best practice guidelines. The interviews were transcribed and Tesch’s eight steps of data analysis were followed to create meaning from the data collected. Themes were identified and grouped together to form new categories. The researcher ensured the validity of the study by conforming to Lincoln and Guba’s model of trustworthiness, which consists of the following four constructs: credibility, transferability, dependability and confirmability. An independent coder assisted with the coding process. In Phase 2, an integrative literature review was conducted in order to identify previous guidelines regarding best practice for patient-centred care. Relevant guidelines were selected, critically appraised, data was extracted and synthesised for the development of a best practice guideline for patient-centred care. An independent appraiser critically appraised the guidelines, thereby ensuring trustworthiness. In Phase 3, the data in Phase 1 and Phase 2 were integrated to formulate a draft best practice guideline for patient-centred care. The guideline was submitted to an expert panel for review and was modified according to the recommendations of the panel, whereby the best practice guideline for patient-centred care in public hospitals in Nelson Mandela Bay was finalized.

- Description: [Integrative executive summary] NCP Chlorchem (Pty) Ltd manufactures and distributes Chlor alkali products such as chlorine, hydrochloric acid, caustic soda flakes, etc. and in the process generates both hazardous and general waste. Following changes in South African waste management legislation in 2011, the organisation’s waste service provider had to increase the costs associated with the handling of site’s hazardous waste. Top management of NCP Chlorchem (Pty) Ltd requested a meeting with the waste service provider in order to establish the reasons behind the price increase. In that meeting, which the researcher attended, the waste service provider explained the changes in waste legislation and how it was going to impact on their business. Top management understood the reasons behind the price increase; however, they requested the waste service provider to review the price increase. The waste service provider gave the top management of NCP Chlorchem (Pty) Ltd assurance that they were going to discuss the price reduction request with their own senior management and would provide feedback. The researcher did not participate in the feedback meetings; however, to this day, NCP Chlorchem (Pty) Ltd still uses the services of the same waste service provider. The effect the escalating annual waste handling costs has had on NCP Chlorchem (Pty) Ltd’s management team led to the study. Environmental impacts have costs that directly impact on company’s bottom line, such as the costs associated with the generation of waste. Although environmental costs are only one of the many costs incurred by businesses, they deserve management’s attention. According to Jasch (2003), there is an apparent lack of awareness and understanding of the magnitude of the environmental costs generated by organisations, and many opportunities for cost savings through good environmental management are lost. However, using a relatively new tool in environmental management, that is, environmental management accounting (EMA), management would ensure that relevant and significant environmental costs are considered when making business decisions (Jasch, 2003). The main purpose of the thesis is to explore the level of awareness of environmental costs associated with hazardous waste within NCP Chlorchem (Pty) Ltd. In order to carry out the study, literature about environmental and cost accounting as well as literature on waste management was reviewed. Questionnaires were distributed to staff members, and meetings were held with different senior personnel. This case study seeks to answer the following questions: What is NCP Chlorchem (Pty) Ltd’s staff members’ level of understanding of waste management? What is the level of awareness of NCP Chlorchem (Pty) Ltd’s staff of environmental costs with regard to the generation, handling, transportation and disposal of hazardous waste? How can the current traditional accounting within the organisation be integrated with environmental management accounting? The findings of the first research objective revealed that staff members knew the site’s waste streams as per the South African legal definition of waste and as identified in the site’s environmental management system documentation. The conceptual approach to waste management is underpinned by the waste hierarchy. The respondents support the waste hierarchy in its approach to waste management, which is prevention of waste, reduction, reuse, recycle and safe disposal of waste as the last resort. Lack of awareness of environmental management, among other things, was cited as the cause of waste. In addition to that, the respondents believe the waste hierarchy can be achieved by employing recycling facilities, following procedures and by carrying out environmental awareness campaigns. Improving process design and control and including changes in raw material was cited, among other things, as the respondents’ perception on how waste can be reduced. The findings of the respondents’ understanding of waste hierarchy revealed that staff members understood waste management. The respondents cited the impacts of waste on the business as financial impact on the business, impact on their bonuses, and possible loss of business. In relation to the second research objective, it was found that staff members knew the hazardous waste streams and identified amongst other waste, sludge and chlorine emissions as NCP Chlorchem (Pty) Ltd’s hazardous waste. However, with regard to environmental management accounting data, an average of 55.1% of respondents were not familiar with the physical and monetary components of EMA. An average of 19.6% of respondents who were aware of EMA might have been senior personnel. It could further be established that those who were familiar with EMA information were actually working with the data, either for reporting purposes, or for employing waste minimisation strategies, as well as awareness purposes, to their juniors. On average, 80% of the respondents perceived the production department as the area within site that has the EMA information.

A case study of a pre-service mathematics education course to grow and develop proficient teaching in mathematics in the intermediate phase

- Description: This research study investigated the ways in which a mathematics module, informed by an enactivist philosophy, enabled pre-service teachers to unpack the reality of their teaching practice in terms of proficient teaching. Given the generally poor mathematics results in South Africa it is not enough for teachers to be merely proficient in Mathematics. They also need to be in a position to explain important mathematical concepts to children in a manner that will encourage and develop an understanding of the basic mathematical concepts. It was my intention with this study to determine whether a mathematics education module, that embraced the underlying themes of enactivism as part of its teaching pedagogy, could have the potential to develop and increase the skills of pre-service teachers’ teaching for proficiency in Mathematics. The mathematics module was underpinned by five themes of enactivism namely: autonomy, embodiment, emergence, sense-making and experience and was designed to supplement the pre-service teachers’ basic skills in Mathematics in the Intermediate Phase. This mathematics module was offered to fourth year pre-service teachers completing a B.Ed. in the Foundation Phase at a private institute specialising in the training of teachers. The theoretical framework was informed by enactivism and how the themes of enactivism could be used as a vehicle to develop teaching proficiency. The study was qualitative in nature and situated within an interpretivist paradigm. The specific perspectives of interpretivism that were used were hermeneutics, phenomenology and reflexivity. The research design was a case study that contained elements of action research and encompassed three phases of data collection. The first phase focused on the pre-service teachers’ approach to teaching Mathematics and what this brought forth in terms of the reality of their teaching practice and the problems they encountered. The second phase undertook to determine what growth and development of teaching proficiency in Mathematics had emerged over the research period. The final phase was undertaken after the pre-service teachers had graduated and were employed as full time teachers in the Intermediate Phase. The analytical framework and lens through which the data was analysed was that of Kilpatrick, Swafford and Findell’s (2001) strands of mathematical proficiency. The argument that I present is that the themes of enactivism did contribute to the growth of the pre-service teachers’ teaching for mathematical proficiency. The themes of embodiment and experience were major contributions in revealing that this was a reality for the pre-service teachers from a practical perspective and was what they would be able to take away with them. However the theme of emergence stood out as the principle that generated the most awareness and growth and which, in turn, affected the participants’ autonomy.

The purpose of this case study was to explore and describe the process of child-centred therapy with a four-year-old child with PTSD. An exploratory descriptive case study approach was utilised as it allowed for an in-depth description of a phenomenon in its therapeutic context. Data was collected through multiple sources to establish a comprehensive database. The data was analysed through Alexander’s content analysis and Guba’s model of trustworthiness. Findings included themes observed in the research participant dealing with PTSD of perfectionism, control, shame, mistrust, needing control, and perfectionism. The therapist’s application of Axline’s principles indicated these principles being enough for treating PTSD in a child. Some of those principles had immediate impact while others were cumulative in their effect.

- Description: The aim of this case study was to investigate the key factors contributing to the high failure and high dropout rates at a FET College. The FET College selected for the purpose of this study is situated in a city in the Eastern Cape. The Minister of Labour declared in 2006 that FET Colleges in South Africa have a central role to play in assisting youth in gaining skills, in order to realise the South African Government’s goal of halving poverty and unemployment by 2014. The South African Government spent R1.9 million on the recapitalisation of colleges in 2005 to improve the FET Sector. According to the Green Paper (DHET, 2012), the FET College sector is weak and the throughput rate of the 2007 NC (V) cohort nationally was 4 percent and the dropout rate between 13 percent and 25 percent. The average pass rate for the successful completion of NC (V) students at FET Colleges in the Eastern Cape was 12 percent for 2007. The research design selected for this study was an explanatory intrinsic case study of a qualitative nature, with the aim to provide a comprehensive depiction of the case. Data was gathered from various sources and at different stages at the particular college campus. Questionnaires, semi-structured interviews and document interrogations were employed to gather descriptive qualitative data. Demographic information on the students who had dropped out assisted in the profiling of students at risk of dropping out of college. The findings derived from the data showed that multiple factors caused the high student dropout and failure rates, prominent among which was a lack of finances, impacting on accommodation and transport, which in turn impacted on student attendance. A lack of motivation and commitment from students seemed to further contribute to the high student failure and dropout rates. In addition, the students’ perceptions and expectations of the FET College, the barriers to academic success and views about support services were explored. Finally, the present circumstances and plans of students who had dropped out were investigated.

- Description: The aim of this study was to investigate the role Excel could play in influencing Mathematics and Mathematical literacy learners’ interpretation of functions and their attitude towards Mathematics. I used a Mathematical Graphical Diagnostic (MGD) test, an attitude questionnaire, a reflective questionnaire and semi-structured interviews as instruments. The MGD test and the attitude questionnaire were given to 72 volunteer grade 11 learners at a former Model C school in Port Elizabeth, in the Eastern Cape. This group included 50 pure Mathematics learners and 22 Mathematical literacy learners. From this group, a smaller group of 10 learners further took part in the rest of the study were they went through an intervention were Excel was used as a teaching tool, covering concepts concerning functions. This group included 6 pure Mathematics and 4 Mathematical literacy learners. The 10 learners then re-wrote the MDG test and refilled the attitude questionnaire after the intervention. A reflective questionnaire was administered to the 10 learners after the intervention, with 5 learners from the 10 undergoing interviews in order to meet the objectives of the study. The administration of the MDG test and attitude questionnaire, interviews and reflective questionnaire enabled me to explore the relationship between learner performance and their attitude towards Mathematics as a subject, as well as the comparing the attitudes and performances between pure Mathematics and Mathematical Literacy learners. The study followed a qualitative research design, with an element of quantitative research. The qualitative data yielded findings that revealed the effectiveness of using Excel in teaching functions while the quantitative data revealed the difference in attitude and ability between pure Mathematics and Mathematical Literacy leaners. The findings of the study revealed that Excel played a major role in improving pure Mathematics learners’ results but not those of the Mathematical Literacy learners.

- Description: The aim of this study was to investigate the role Excel could play in influencing Mathematics and Mathematical literacy learners’ interpretation of functions and their attitude towards Mathematics. I used a Mathematical Graphical Diagnostic (MGD) test, an attitude questionnaire, a reflective questionnaire and semi-structured interviews as instruments. The MGD test and the attitude questionnaire were given to 72 volunteer grade 11 learners at a former Model C school in Port Elizabeth, in the Eastern Cape. This group included 50 pure Mathematics learners and 22 Mathematical literacy learners. From this group, a smaller group of 10 learners further took part in the rest of the study were they went through an intervention were Excel was used as a teaching tool, covering concepts concerning functions. This group included 6 pure Mathematics and 4 Mathematical literacy learners. The 10 learners then re-wrote the MDG test and refilled the attitude questionnaire after the intervention. A reflective questionnaire was administered to the 10 learners after the intervention, with 5 learners from the 10 undergoing interviews in order to meet the objectives of the study. The administration of the MDG test and attitude questionnaire, interviews and reflective questionnaire enabled me to explore the relationship between learner performance and their attitude towards Mathematics as a subject, as well as the comparing the attitudes and performances between pure Mathematics and Mathematical Literacy learners. The study followed a qualitative research design, with an element of quantitative research. The qualitative data yielded findings that revealed the effectiveness of using Excel in teaching functions while the quantitative data revealed the difference in attitude and ability between pure Mathematics and Mathematical Literacy leaners. The findings of the study revealed that Excel played a major role in improving pure Mathematics learners’ results but not those of the Mathematical Literacy learners. The study also showed that technology does not necessarily impact on learners’ attitudes positively.

- Description: The problems of reading and incomprehension found in South African schools are often linked to children‟s differences of phonological acquisition rates and the articulation of consonants. This is according to the report of the Impact Study of the System Method for Reading Success study (SMRS) of 2009. This problem has always been associated with the racial inequalities that have previously ruled the South African education system. An understanding of the existence of the differences in children‟s articulation of consonants between the English-speaking and the isiXhosa-speaking children may lead to further understanding of the causes of such differences and the application of strategies that are aimed at remedying that situation. While many studies have been conducted in the area of language acquisition, this study found it necessary to contribute further to this debate. This study investigated the different rates of consonant articulation between pre-school-going Englishspeaking and isiXhosa-speaking children of 2-6 years of age. The main aim was to establish which of these two cohorts have early phonological acquisition of consonants and, therefore, master their articulation and why. 26 children from the two pre-schools within the East London directorate weren sampled, 13 consisting of females and males from each of the two pre-primary schools. This study used informal interviews and case study as the means of data collection as well as a case study as its investigation strategy. Children‟s speech utterances were recorded in order to analyse and compare with respect to order of acquisition, types of errors as well as the ages at which consonants were acquired. This study ensured a high degree of validity as well as giving due consideration to ethical matters in order to ensure the reliability of the results.

The implications of these results to education stakeholders, particularly the teachers and other related professionals who deal with children with articulation disorders on a daily basis, will create an understanding as well as an awareness of the existence of such problems. Policies formulated will have to take the existence of articulation disorders into consideration. The distribution of resources relevant to the needs of children will include and cater for children with such disorders. Further research is recommended to investigate more around this area of study to a point where solutions for the existing differences of articulation of consonants for one group of children over another are realised.The study found that isiXhosa speaking children have earlier consonant acquisition than English-speaking children do.

- Description: The study compared fresh milk as group control to three different milk replacers (Blossom® Easymix, Denkavit® Milk-Bar and Surromel® Calf) and two milk supplements (Byboost Calf® and SupaCalf®) mixed with fresh milk at Fernwood Dairy Farm in Alexandria, Eastern Cape. The objectives of the study were to compare the growth rate of the calves in a trial from day two to 49 at weaning and to calculate average daily gain with the aim of comparison of the cost/weight gain ratio of each liquid feed fed. Sixty Holstein (60) heifer calves were used in a completely randomised design to calculate average daily body weight gains in the six calf groups fed six different milk feeds. Calves were fed four litres liquid feeds every day. Water and solid feeds (Olifantskop® calf starter pellets and lucerne hay) were available. Results comprise of details regarding weather conditions, weight gain results, and body stature measurements, including body weight, wither height, hip height and heart girth. Statistical analysis of the weight gain and body stature measurements was essential to determine the usefulness and reliability of the research data. Results of the statistical calculations indicated that the body weight gain data provided very useful results with statistical significant differences between the six groups (F=5.09; P=0.0008). Body stature measurements are not as reliable. Results are summarised as follows: Liquid feed Cost/kg weight gain Average daily gain • Fresh milk R 34.29 0.50 kg/day • Blossom®Easymix R39.25 0.35 kg/day • Denkavit® Milk-Bar R22.57 0.42 kg/day • Surromel® Calf R23.48 0.39 kg/day • Fresh milk + Byboost Calf® R37.46 0.47 kg/day • Fresh milk +SupaCalf® R29.76 0.62 kg/day Comparison of the cost/weight gain ratio of milk replacers and fresh milk draws the following conclusions: The cost of feeding a calf was significantly lower when milk replacers Denkavit® and Surromel® were used; however this yielded a lower average daily gain when compared with that of fresh milk. Denkavit® milk replacer had a lower cost than fresh milk in terms of the average daily gain. The cost of the Denkavit was the lowest of all the products (R22.56/kg) and was in the fourth position in weight gain (0.42kg/day). Surromel® lay in the fifth place for both cost (R23.48/kg) and weight gain (0.39 kg/day). Blossom® Easymix milk replacer had a higher cost than fresh milk. Blossom was the most costly of all the feeds (R39.25/kg) but had the lowest average daily gain (0.35 kg/day). Comparison of fresh milk plus additives to fresh milk alone: The use of SupaCalf® additive to fresh milk resulted in the highest average daily gain of 0.62 kg/day at a cost of R29.76/kg which was more cost effective than the control fresh milk group (0.50 kg/day, R34.29/kg), When using Byboost® additive the average daily gain of 0.47 kg/day at a cost of R37.46, less cost effective than fresh milk (0.50 kg/day, R34.29). Statistical analysis of body stature measurements yielded one significant result(F=3.20; p=0.0140) confirming that use of SupaCalf® additive resulted in the biggest heart girth increase at 16.90 cm and the smallest being Blossom® Easymix at 11.88 cm. Figure for the control fresh milk group was 12.86 cm. Dairy calves all over the world are fed different feeds depending on the farm owner or manager’s preference and budget. For those who have been in the industry for a while as well as the newcomers, this study can help when weighing options and deciding on which feeds to use.

A comparative evolutionary approach to gum-feeding in Galago Moholi and Microcebus Griseorufus

- Description: Gums are soluble plant exudates rich in complex carbohydrates. In primates, the consumption of gum (gummivory) has been described as a primitive, fall-back diet exhibited when other food sources become scarce, particularly during dry periods. In apparent support for this interpretation, gummivory is often observed in nocturnal strepsirhines (tooth-combed primates) believed to have retained many primitive features. The complex carbohydrates in gums, however, are also known to be difficult to digest, and require particular alimentary adaptations. The hypothesis of a primitive diet predicts that gummivorous strepsirhines should use homologous digestive strategies, while the presence of different digestive adaptations in different lineages would suggest convergent evolution. I compared the digestive adaptations to gummivory in two small strepsirhine taxa, African lesser bushbabies (Galago moholi) and Malagasy reddish-grey mouse lemurs (Microcebus griseorufus). Both taxa digest gum primarily by fermentation, and have enlarged caeca for this process, but only G. moholi has an ansa coli in which digestion can be continued. In captive feeding experiments, the faeces of wild-caught G. moholi and M. griseorufus showed no significant difference in their digestive efficiency of gum compared with a control food (banana), and the banana and gum samples showed no significant difference in nutrient concentration and overall composition. To gain a broader understanding of the origins of gummivory in strepsirhines, I used a phylogenetic method to reconstruct their dietary evolution. My results indicate that gummivory evolved convergently in several primate lineages, apparently in response to environmental hypervariability. I conducted biochemical analyses of the secondary compounds found in gums that are regularly consumed, and preliminary results show that Commiphora spp. have a number of compounds, while Acacia spp. show no such traces. The absence of secondary compounds from M. griseorufus faeces suggests that the animals have physiological means for either converting them into digestible products or detoxifying and excreting them in their urine. Finally, I compared the distribution patterns of G. moholi and M. griseorufus with climatic parameters; both study taxa inhabit regions in which the dry season is characterised by little to no rainfall, a drought that may persist for months. Similar climatic regions are occupied by other gum-feeders, including the marsupial gliders (Petauridae) of Australia.

- Description: In this study, we report on the covalent linking of carboxylic acid functionalized silica nanoparticles with zinc phthalocyanine mono-substituted non-peripherally and peripherally with either a 4-amino phenoxy (1, peripheral and 2, non-peripheral) or an amino group (3 peripheral). The grafting is achieved via the formation of an amide bond between the carboxylic acid of the silica nanoparticles and the amino group of the phthalocyanine complexes. The hybrid nanoparticles retained the amorphous nature of silica nanoparticles after conjugation. A slight decrease in fluorescence and a general improvement in triplet quantum yields compared to free Pcs were observed. Triplet lifetimes for 2-SiNPs and 3-SiNPs also improved when compared to the free phthalocyanine. The changes in singlet oxygen quantum yields upon conjugation were minimal.

- Description: This thesis explored different perceptions of extrinsic and intrinsic motivation in an intercultural context. The main objective of this study was to investigate similarities and differences concerning extrinsic and intrinsic motivation in the workplace between the German and the South African culture by examining individuals with working experience and tertiary education. It provides background information about motivation and a historical overview of previous and current motivational theories as well as cultural influences and differences. In addition, regarding the two cultures the researcher aimed to investigate similarities and differences between other demographics such as gender, age and income. The literature review provides information about extrinsic and intrinsic motivation retrieved from previous research and puts it into an intercultural context. The researcher conducted a quantitative, exploratory study. The data was gathered using an existing research instrument, which was distributed online. The sample comprised 374 respondents. This sample was conducted by a combination of quota and snowball sampling. The obtained data is evaluated and presented in text and table form. The results revealed preferences for intrinsic motivators for the whole sample and higher motivation for the South African part of the sample. Demographic characteristics played a minor role.

- Description: Online information access on mobile devices is increasing as a result of the growth in the use of Internet-enabled handheld (or pocket-size) devices. The combined influence of recent enabling technologies such as Web 2.0, mobile app stores and improved wireless networks have driven the increase in online applications that allow users to access various types of information on mobile devices regardless of time and location. Examples of such applications (usually shortened to app) include: social media, such as FacebookTM App and TwitterTM App, banking applications such as (Standard Bank South Africa)TM Mobile Banking App and First National Bank (FNB) BankingTM App, and news application such as news 24TM App and BBCTM News App. Online businesses involved in buying, selling and business transaction processing activities via the Internet have exploited the opportunity to extend electronic commerce (e-commerce) initiatives into mobile commerce (m-commerce). Online businesses that interact with end user customers implement business to consumer (B2C) m-commerce applications that enable customers to access and browse product catalogue information on mobile devices, anytime, anywhere. Customers accessing electronic product catalogue information on a mobile device face a number of challenges such as a long list of products presented on a small screen and a longer information download time. These challenges mainly originate from the limiting and dynamic nature of the mobile apps operating environment, for example, dynamic location, bandwidth fluctuations and, diverse and limited device features, collectively referred to as context. The goal of this research was to design and implement a context-aware model that can be incorporated into an m-commerce application in order to improve the presentation of product catalogue information on m-commerce storefronts. The motivation for selecting product catalogue is prompted by literature which indicates that improved presentation of information in m-commerce (and e-commerce) applications has a positive impact on usability of the websites. Usable m-commerce (and e-commerce) websites improve efficiency in consumer behaviour that impacts sales, profits and business growth. The context-aware model aimed at collecting context information within the user environment and utilising it to determine optimal retrieval and presentation of product catalogue in m-commerce. An integrated logical context sensor and Mathematical algorithms were implemented in the context-aware model. The integrated logical context sensor was responsible for the collection of different types of predetermined context information such as device specification or capabilities, connection bandwidth, location and time of the day as well as the user profile. The algorithms transformed the collected context information into usable formats and enabled optimal retrieval and presentation of product catalogue data on a specific mobile device. Open-source implementation tools were utilised to implement components of the model including: HTML5, PhP, JavaScript and MySQL database. The context-aware model was incorporated into an existing m-commerce application. Two user evaluation studies were conducted during the course of the research. The first evaluation was to evaluate the accuracy of information collected by the context sensor component of the model. This survey was conducted with a sample of 30 users from different countries across the world. In-between the context sensor and main evaluation surveys, a pilot study was conducted with a sample of 19 users with great experience in mobile application development and use from SAP Next Business and Technology, Africa. Finally an overall user evaluation study was conducted with a sample of 30 users from a remote area called Kgautswane in Limpopo Province, South Africa. The results obtained indicate that the context-aware model was able to determine accurate context information in real-time and effectively determine how much product information should be retrieved and how the information should be presented on a mobile device interface. Two main contributions emerged from the research, first the research contributed to the field of mobile Human Computer Interaction. During the research, techniques of evaluating and improving usability of mobile applications were demonstrated. Secondly, the research made a significant contribution to the upcoming field of context-aware computing. The research brought clarity with regard to context-aware computing which is lacking in existing, current research despite the field’s proven impact of improving usability of applications. Researchers can utilise contributions made in this research to develop further techniques and usable context-aware solutions.

- Description: Online information access on mobile devices is increasing as a result of the growth in the use of Internet-enabled handheld (or pocket-size) devices. The combined influence of recent enabling technologies such as Web 2.0, mobile app stores and improved wireless networks have driven the increase in online applications that allow users to access various types of information on mobile devices regardless of time and location. Examples of such applications (usually shortened to app) include: social media, such as FacebookTM App and TwitterTM App, banking applications such as (Standard Bank South Africa)TM Mobile Banking App and First National Bank (FNB) BankingTM App, and news application such as news 24TM App and BBCTM News App. Online businesses involved in buying, selling and business transaction processing activities via the Internet have exploited the opportunity to extend electronic commerce (e-commerce) initiatives into mobile commerce (m-commerce). Online businesses that interact with end user customers implement business to consumer (B2C) m-commerce applications that enable customers to access and browse product catalogue information on mobile devices, anytime, anywhere. Customers accessing electronic product catalogue information on a mobile device face a number of challenges such as a long list of products presented on a small screen and a longer information download time.
