- Description: This study is an investigation on lessons learnt when the language of learners is maintained for teaching and learning mathematics beyond Grade 3 for another 3 years. It is undertaken in Cofimvaba, a rural village of the Eastern Cape in South Africa. We investigate lessons that can be learnt from the Mother Tongue based- Bilingual Education (MTbBE) strategy, that can be replicated. South Africa post-1994 has a Language-in-Education Policy (1997) that provides for the use of all official languages as Languages of Teaching and Learning (LoLT), this has remained on paper as the schooling system focusses on an early –exit model of three years of the Mother Tongue Education (MTE) for the Foundation Phase (FP) then exit to English instruction in Grade 4; this applies to African language learners only. English and Afrikaans speakers have mother tongue education from cradle to university; a benefit they have enjoyed pre- and post-apartheid. Various studies have been conducted to understand the relationship between language and mathematics learning as it is crucial to design mathematics instruction for students who are English Learners (ELs) and/or bilingual. However, in South Africa, there had not been a direct exploration of the achievement of learners in mathematics when their mother tongue is used and sustained throughout the first six years of learning mathematics, while English is a supportive resource. This is the focus of this study. The study lends itself to the adoption of a mixed methods design (QUALT+QUANT), while also employing documents, observation and test scores of learners to obtain data. Content analysis and thematic analysis approaches were used in analyzing the qualitative-type data while a statistical approach was used in the analysis of quantitative data. The main aim of the study was to establish whether in the Cofimvaba pilot, there is any evidence to make a case for extending Mother Tongue Based-bilingual Education (MTBBE) beyond Grade 3 for black African children. Another aim, was to highlight and document the effort that was the first of its kind in South Africa, undertaken in a small rural area to develop isiXhosa as language of Mathematics and Science. The most salient of this effort was the fact that it was underpinned by deliberate theoretical and empirical foundations central to language policy and planning. The finding of this study is that the use of isiXhosa for MTbBE was effective for boosting mathematical and science skills in the mother tongue and English in Grade 6 as demonstrated in Chapter 7 and 8. Lastly, this study demonstrates the power of political will and how a decision backed by financial investment can transform the wider system despite the challenges of transformation. For the first time in the history of education; a poor department has stuck to its guns; unwearied by the negativity surrounding the development of African languages. It committed to the cause of improving the academic achievement of the poorest of the poor. Historically, in implementing a Mathematics Curriculum, the Department of Education (both officials and teachers) has never efficiently implemented the LiEP (1997) in the manner spelt out in its policy documents viz, multilingualism as the norm. The focus has been on a perspective of learners who are learning and must English, then mathematics and ways to get them to know English at all costs. This view creates inequities in the classroom because it places emphasis on what learners don’t know or can’t do. In contrast, this study proposes a sociocultural perspective that shifts away from deficiency models of bilingual learners and instead focuses on describing the resources bilingual students use to communicate mathematically (Moskovich, 1988). Without this shift we will have a limited view of these learners and will design instruction that neglects the competencies they bring to mathematics classrooms. If, instead, we learn to recognize the mathematical ideas these students express in spite of their accents, code-switching, or missing vocabulary, then instruction can build on students’ competencies and resources (Moskovich, 1998). This study recommends a plethora of strategies that must be taken by the Department of Education to widen epistemological access to mathematics for African language learners using MTbBE as a viable strategy.

- Description: This collection of short stories experiments with the idea of the text as it constitutes the world just as much as it is constituted by the world. These short stories use the text as a way to respond to struggles faced by people whose identities do not conform to society’s standards. The stories in here navigate between fantastic and experiential writing which allows the text to speak in its own language. The writing is influenced by that of Mthuthuzeli Matshoba for the realist approach in telling the stories. Ayi Kwei Armah’s writing in Fragments for experientialism that focuses on the dead and the living and which makes specific references to the idea of home – particularly for those who always find it hard to belong. And that of Bruce Sterling’s creation of explosive imagery in science fiction that sticks in the reader’s mind as portrayed in his short story we see things differently. Angela Carter’s brilliance in writing short stories and her approach to magical realism has also been a powerful influence. In telling these stories using a hybrid/fluid approach, I hope to come to terms with being a different “being”. It is to find ways of telling myself that it is okay to be queer, that to be a misfit is no sin. To say this in a language that gives meaning to my own struggles of being. This work is a combination of three disjointed moments of the narrator’s life experiences which are exposed in three sections; It’s My Hand That Wrote, (Un)Tying The Knot and Thoughts. The aim of creating these three moments is to let the reader dive a variety of “truths” of the narrator’s life, instead of aiming to achieve a coherent single “Truth” about one’s life. It’s My Hand That Wrote explores both the unusual and inconsistency of life in a chaotic but explorative fashion.

- Description: This study examined job characteristics and organisational citizenship behaviour among employees in a previously disadvantaged South African University. A structured questionnaire was used to collect data from 149 randomly selected participants. A 5-point Likert scale job characteristics survey by Hackman and Oldham (1975) was used to measure job characteristics while, a 5-point Likert scale by Lee and Allen (2002) on organisational citizenship behaviour was used to measure employee’s organisational citizenship behaviour. Different statistical techniques such as Spearman rho correlation technique and Regression analysis were used to analyse data. The results showed that task significance, skills variety, autonomy and feedback are significantly positively related to organisational citizenship behaviour. There was a non-significant negative relationship between task identity and organisational citizenship behaviour. A combination of two or more job characteristics dimensions were found to report a higher proportion of variance in organisational citizenship behaviour than any one job characteristic separately. The study, thus, recommends that managers must design employees’ jobs or tasks that are more meaningful to stimulate the display of organisational citizenship behaviour. Initiatives that stimulate the use of a variety of skills, promotes feedback, promote task significance and autonomy were suggested as solutions to stimulate the display of OCB. The prevalence of such dimensions on one’s job increase motivation and satisfaction therefore contributing positively towards organisational citizenship behaviour.

- Description: This thesis will interrogate the spatial dynamics and configurations of one of the country’s most prominent cities: Johannesburg. Johannesburg has been, and continues to be, a central focus in the nation’s imaginary. There is a trend within South African science fiction (sf) – both literature and film – to portray Johannesburg as a dystopian, post-law, poverty-stricken space as a means of conceptualising the socioeconomic situation within the country. This study will isolate Johannesburg-based works of sf and interrogate why authors and filmmakers disproportionately return to this setting. Investigated are three contemporary works, namely, Zoo City (2010) by Lauren Beukes, Neill Blomkamp’s film, Chappie (2015), and Dub Steps (2015) by Andrew Miller. This study explores the ways in which South African works of sf serve as social and political critique in the post-apartheid era of financial disparity, the formation of new boundaries, divisions of space and privilege, and the dereliction of critical infrastructure. The primary methodology of this thesis is that of Marxist literary analysis (specifically with reference to Louis Althusser’s theoretical models), which will be conducted alongside discussions of authentic history of the country as well as political developments in order to illustrate how South African sf critically engages with, and succinctly critiques, its context. The aesthetics of African sf are inseparable from the politics of the past and the current moment and through the aesthetics of the future, South Africans can reimagine the politics of the now. This study therefore also revisits a selection of non-sf Johannesburg-set novels published post-1925 and argues that these texts can be studied as early examples of South African dystopian writing. In doing so, this study illustrates that dystopian writing about and in South Africa is not an advent of the 21st century, but an extension of a long history of critical engagement. This thesis suggests that the dystopian genre is helpful in reframing the issues of the present (and the past) so that some form of meaningful change is theorized. The underlying impulse of dystopian cultural production is ultimately hopeful: a worse context is imagined to warn society of its follies so that these shortcomings and issues can be corrected, thereby avoiding the disastrous world(s) portrayed in the fiction. In this way, this study contends that local sf should not be inextricably linked to the melancholia that thoughts of dystopia bring about. Rather, the nuanced criticism contained within these dystopian texts is testament to the country’s ever-enduring spirit of change and transformation.

Joint Modelling Inference for Longitudinal and Time To Event Data with Application to Biomarkers in Medical and Clinical Studies

- Description: In the past couple of decades, longitudinal and survival data analysis have emerged as important and popular concepts of biostatistics and statistics for disease modelling. In recent years, these two statistics concepts have been combined to develop a joint model for longitudinal and survival data analysis. The Joint model is a simultaneous modelling application of longitudinal and survival data while taking into account a possible association between them. In this thesis, three sub-topics (Conditional score approach, estimating equation approach, and modified Cholesky decomposition approach) are utilised to model the association if the independence assumption is violated. Using the conditional score approach, the study investigated the association between longitudinal covariates and the time-to-event process to examine the within-subject measurement error that could influence estimation when the assumption of normality and mutual independence is violated. Given the assumption violation, I proposed an estimating equation approach based on the conditional score to relax parametric distributional assumptions for repeated measures of random effects. I jointly modelled the time-dependent biomarkers and event times using the Cox model with intermittent time-dependent covariates measure, in which the longitudinal model was used to characterize the biomarker underlying (unobservable) trajectory and incorporated as a latent time-dependent covariate in the survival model to predict failure times. Estimates of the parameters were obtained by a restricted maximum likelihood estimate (REML). A modified Cholesky decomposition method was used to capture the within-subject covariance for a positive definite and symmetric matrix, with the assumption that the observed data from different subjects are independent. I illustrated the proposed method by a real data set from a lung study and simulation. An extension to the joint model of longitudinal-survival data was also proposed, in which the longitudinal data has a cumulative and weighted effect on the hazard event function. Using a Bayesian parametric method, I proposed a skewed weighted probability density function to estimate the parameters. The weighted cumulative effect used enabled different longitudinal profiles to be incorporated over time in calculating the hazard ratio between the subjects. The proposed functions provide greater flexibility for modelling the association structure of different longitudinal and survival sub-model. The focus was on the association between the biomarker (serum creatinine, sCr) and the development of end-stage renal disease (ESRD). Since the effect of sCr biomarker is anticipated to be a cumulative effect, with the development of sCr biomarker over time leading to progressively higher damage of the kidney. The approach was applied a simulation for validation of the proposed method

- Description: This thesis examines the memoirs of two South Africa female writers: Noni Jabavu and Sisonke Msimang. In analysing their memoirs, this thesis sets out to contribute to the scholarship which centres the voices of Black women writers. It explores how both writers interrogate the concepts of home, exile and transnationalism. My focus is on the ways in which the writers theorise questions of belonging, and the extent to which their writing provides the opportunity to give voice to the complex nature of belonging. I read the narratives from these two writers alongside each other, as Noni Jabavu is Sisonke Msimang’s literary ancestor. By looking at their works alongside each other, this thesis becomes an intergenerational conversation between the past and the present. Using Black feminist thought and migratory subjectivity, this thesis examines the ways in which these writers connect the personal and the political. Noni and Sisonke navigate the private spaces of home in conversation with the political experience of exile and the nation. In the second chapter, I explore home as ekhaya, isizwe and an imaginary homeland. Ekhaya is the isiXhosa word denoting the family home, where there is a network of family rather than a nuclear family. Home is also isizwe: the isiXhosa word which evokes the nation state, which takes on layered meanings in the context of colonialism and apartheid. Home can also be an imaginary homeland, which is an imagined version of home after a long absence such as exile. In the third chapter, I examine three forms of exile: internal exile, estrangement and political exile. Finally, in chapter four, I analyse transnationalism: a border-crossing which raises questions of power, mobility and kinship. Looking at home, exile and transnationalism together allows for an exploration which challenges taken-for-granted ideas about place and identity. These memoirs illuminate the ways in which Black women constitute and reconstitute their identities according to the places which they access through travel.

- Description: Although several languages in the Khoekhoe branch were historically spoken alongside Afrikaans in bilingual speech communities throughout the Western and Northern Cape, the last century has seen abrupt and catastrophic language loss, resulting in a shift from a bilingual to a monolingual paradigm. However, a number of ethnobotanical surveys conducted in the Namaqualand region of the Northern Cape over the last forty years have recorded the retention of Khoekhoe-branch plant names by monolingual Afrikaans speakers. Such surveys make no attempt to source these loanwords to their Khoekhoe-branch targets, do not make use of the standardised Namibian Khoekhoe orthography, and often resort to transcribing loaned click consonants using only ‘t’. This study undertakes a sociohistorical linguistic investigation into the etymological origins and contemporary usage of these loaned plant names in order to develop a clearer understanding of language contact and lexical borrowing in the Namaqualand region. Following the lexicographical compilation of a representative corpus of loanwords, this study conducts a series of semi-structured interviews with monolingual speakers of Namaqualand Afrikaans. Qualitative sociolinguistic analysis of these interviews reveals that, although loanwords are perceived to be of Nama origin, they are semantically opaque beyond pragmatic reference. Preliminary phonological observations identify a loss of phonemic contrastivity in loaned clicks coupled with a high incidence of variability, and suggest epenthetic stop insertion and epenthetic nasalisation as two possible strategies facilitating click loan. Synthesising these ob servations, this study speculates that the use of loanwords hosting clicks may enjoy a degree of covert prestige in Namaqualand Afrikaans, which may in turn shed light on historical sociolinguistic processes of click diffusion. It recommends that urgent and immediate attention be focused on the usage, sociolinguistic status, and regional variation of Nama within the Northern Cape, and advocates strongly for cooperation and improved communication between linguists and ethnobotanists.

- Description: Although several languages in the Khoekhoe branch were historically spoken alongside Afrikaans in bilingual speech communities throughout the Western and Northern Cape, the last century has seen abrupt and catastrophic language loss, resulting in a shift from a bilingual to a monolingual paradigm. However, a number of ethnobotanical surveys conducted in the Namaqualand region of the Northern Cape over the last forty years have recorded the retention of Khoekhoe-branch plant names by monolingual Afrikaans speakers. Such surveys make no attempt to source these loanwords to their Khoekhoe-branch targets, do not make use of the standardised Namibian Khoekhoe orthography, and often resort to transcribing loaned click consonants using only ‘t’. This study undertakes a sociohistorical linguistic investigation into the etymological origins and contemporary usage of these loaned plant names in order to develop a clearer understanding of language contact and lexical borrowing in the Namaqualand region. Following the lexicographical compilation of a representative corpus of loanwords, this study conducts a series of semi-structured interviews with monolingual speakers of Namaqualand Afrikaans. Qualitative sociolinguistic analysis of these interviews reveals that, although loanwords are perceived to be of Nama origin, they are semantically opaque beyond pragmatic reference.

- Description: The purpose of this research study was to explore and describe the knowledge and the level of awareness of drowning risks amongst adolescents in the Nelson Mandela Metropole, Eastern Cape Province, and South Africa. Drowning is defined as the “process of experiencing respiratory impairment from either submersion or immersion into a water medium” (van Beeck et al 2005:853). Global statistics place drowning as being the third foremost cause of unintentional death worldwide (WHO 2013). The World Health Organization reports that more than 90% of the estimated 370 000 drowning fatalities recorded in 2012 occurred in low and middle income countries (WHO 2014). A qualitative descriptive explorative contextual design was employed in this research study. A non-probability convenience sampling method was used. Adolescents aged 10- 13 years old who attend a public primary school and model C primary school in Nelson Mandela Metropole area in the Eastern Cape Province were the target population who had the specific characteristics of interest and significance to the research phenomenon (Asiamah et al 2017). Four focus group interviews were conducted. The groups consisted of five to ten participants grouped together to discuss the matter. Field notes were also taken by the researcher on what was heard, observed, thought and experienced during the interview process (Streubert & Carpenter 2007). Ethical principles were maintained as well as the concepts of trustworthiness were applied throughout this study.Data analysis was done using Tesch’s approach to open coding in qualitative research. A total of six themes and seven sub-themes arose during the analysis of the data and were completely discussed. The findings suggest that most of the participants are quite aware and knowledgeable of the potential risks that predispose an individual to drowning. The consequences of what happens when a victim is exposed to drowning, however, requires more insight. The risk of being unsupervised as well as not being able to swim was echoed in most of the group interviews. vii A noteworthy finding was the fact that the participants who were involved with some form of water safety programme/s at school were very articulate in their responses to the questions. It was recommended that educational programmes ought to be aligned with current evidence which is reflective of the region’s demographics and dynamics. Even though all researchers do not share the sentiments that swim proficiencies heighten the safety of the individual in and around water, the need for ongoing research initiatives is a significant stimulus that will generate new evidence and inform current preventive strategies. Identification and awareness of drowning risks require a foundation of comprehension in order to better understand and interpret the consequences of these risks. Learn to swim or swim orientation initiatives could potentially assist at primary school level with the safety levels of learners.

- Description: Background: Food preparers and food handlers seem to face difficulties in identifying activities that render food unsafe as a result of food contamination during food preparation. Research has shown that food preparation is a global problem and a potential health risk which can result in food-borne diseases as a result of a lack of knowledge on the principles of hygienic practices and negative attitudes when handling food. Aim: This study aims to determine the knowledge, attitudes and behaviours that motivate food preparers in safe food preparation. Method: Building on existing work in understanding this phenomenon it asks: A purposive sample of male and female participants who prepare food at home were asked to complete a questionnaire. The questionnaire items were developed through focus group interviews and after a pilot study, presented to participants to complete. The items were subjected to principal component analysis (factor analysis), yielding a six-factor solution. The factor means, standard deviations were calculated and reliability was determined for each factor using Cronbach’s alpha as a measure of internal consistency. Group differences were determined through independent samples t-tests and anova. Results: The quantitative analysis demonstrated that food preparers have a fair knowledge and perception of how to prevent contamination. However, their behaviour is various aspects of food preparation might at times put them at risk for contamination. With regards to attitude, when comparing groups, people who prepare food with love and care demonstrated a more positive attitude towards food preparation than those who are less passionate to prepare food. On this basis, hygiene education should focus on the perceived threat to health as cues to action in changing attitudes and adherence to recommendations on hygiene. Conclusion: Further research is required to solicit the views of respondents below the age of 18 with regard to food-handling practices in pre-prepared food to ascertain and prevent further contamination and ensure food safety.

- Description: The dissertation examines the Ugandan labour dispute resolution system by undertaking an analysis of international labour standards and a case study of South Africa’s labour dispute system. The study pronounces the legislative provisions of the Employment Act and Labour Disputes (Arbitration and Settlement) Act that exist for the effective and efficient resolution of labour disputes through an alternative dispute resolution (ADR) system. The study contends for the provision of a proactive and expeditious dispute resolution system that helps to resolve labour disputes in the most effective and efficient manner, without necessarily having to resort to the courts. The dissertation further examines the provisions of relevant international labour standards on labour dispute resolution to ascertain their adequacy as part frameworks that apply to Uganda’s obligation to provide ADR systems that respond to the needs of the labour relations community. The study contends that ratifying particular ILO conventions creates obligations upon a country to comply and apply provisions of these conventions in national legislation. It is further argued that by having ratified those international labour standards that provide for ADR, Uganda assumes specific obligations under international law, enjoining the country to provide the required ADR system of conciliation and arbitration, which is reliable and trusted by the countries citizens. A case study of South Africa is adopted with the primary focus on whether Uganda can learn from South African’s ADR system which is arguably more effective and efficient. South Africa has a labour dispute resolution system that has influenced majority of the Southern African Development Community (SADAC) law, hence prompting this study to borrow its ADR system predominantly the Commission for Conciliation Mediation and Arbitration (CCMA). Despite the differences between Uganda and South Africa, the study also indicates fundamental similarities. Preferably, disputes should be resolved at conciliation level, resulting in the minority of disputes being referred to arbitration or the Industrial Court. This is far from the reality of the situation in Uganda. The study acknowledges that the Labour Disputes (Arbitration and Settlement) Act and Employment Act have put up provisions to establish a fast and effective labour dispute system, however, the gap exists at implementing these effective provisions in the Labour Disputes (Arbitration and Settlement) Act and the Employment Act. These lacunae in implementation make the attainment of an effective and efficient labour dispute resolution difficult. For this reason, the author proposes several remedial interventions in line with international labour standards and lessons from South Africa’s system that look to the future and the continued provision of fast, effective, and user-friendly ADR services. For Uganda to solve successfully apply these remedies, a strong political will as well as concerted efforts from all role players in the labour relations community is required.

- Description: Opuntia ficus-indica is a succulent plant species that originated from Mexico and parts of neighbouring middle-America and introduced in South Africa by white settlers in the eighteenth century. The species is now categorized as invasive in South Africa but has both commercial and non-market uses. This study evaluated the livelihood uses and local perceptions of O. ficus-indica of rural residents in Makana, Ngqushwa and Raymond Mhlaba Local Municipalities in the Eastern Cape province in South Africa. Data on the livelihood uses and local perceptions on the species in the study area were gathered through community focus group discussions and household surveys using semi-structured questionnaires between June 2018 and August 2019. A sample of 150 participants selected via snowball-sampling technique provided detailed accounts on utilization of O. ficus-indica in the study area. The importance of O. ficus-indica as a useful plant species was ubiquitously perceived, with all respondents reporting its contribution towards their livelihood needs and more than three quarters (88.0%) using the species on a regular basis. Majority of the respondents (41.0%) regarded O. ficus-indica as an important source of cash income while about a third (33.0%) regarded the species as an important source of food products and nutrition. Interviews with respondents revealed that O. ficusindica is currently being harvested from the wild with 73.3% of the respondents reporting that the abundance of the species was decreasing. The positive socioeconomic contributions of O. ficus-indica need to be taken into account when assessing the costs resulting from invasions caused by alien plant species. This study is a crucial starting point in trying to understand and initiate the management of alien invasive species such as O. ficus-indica. Results of this study are also important for understanding local peoples’ perceptions of new introductions and management of existing alien plants in the province.

- Description: South Africa is striving to attain quality equal education; however, this ideal is affected by various factors such as discrimination, learner-related challenges (e.g. dilapidated rural schools, poverty, and violence), educator-related challenges (e.g. low morale and motivation, and poor administration and management of schools), and governmental issues (e.g. a lack of will, lacklustre attitudes, and an inability to deliver resources and/or services). While the National Department of Basic Education is battling to eradicate the backlog of school infrastructure and maintenance, mud schools are still prevalent in rural areas. The present state of poverty-stricken areas is most affected by the mentioned challenges and, as a result, it is necessary to determine the nature and extent of the consequences in terms of academic performance. This study, therefore, investigated the reality of the current rural school situation by investigating the perceptions of learners on the effect of infrastructure development on their academic performance in public secondary schools. Three secondary schools in the Motherwell area in Port Elizabeth were chosen for the research setting. A quantitative research approach was deemed suitable for the study, and a questionnaire was utilised for data collection. A total of 151 questionnaires were completed. The key findings derived from the data indicated that inadequate infrastructure has a negative impact on academic performance. Some of the key issues pertaining to infrastructure included inadequate leisure areas, laboratories, libraries, and sport fields. Overcrowding in classrooms were also found to be prevalent, and posed a major barrier to learning. The findings of the study provided insights into the reality of rural education and were used as a basis for offering recommendations that may assist stakeholders to improve the current situation.

- Description: After almost 25 years of democracy in South Africa, not everyone has access to the same quality education. The responsibility of creating a literate society however cannot rely on the national government and schools alone, but instead needs to fall on the shoulders of various stakeholders. Volunteers in particular have an important role to play in remedying the current literacy crisis experienced in South Africa. This study takes the form of a case study approach and examines the experiences of Project Read literacy volunteers. A telephonic survey and two focus group discussions were conducted in order to determine who it is that volunteers for the programme; what prompts these particular individuals to volunteer; the perceived benefits of volunteering; and how volunteers report on their volunteering experiences. Although the Project Read programme is focused on the early literacy development of learners, volunteers seemed to undergo a developmental process themselves – something they had not anticipated at the start of their volunteering journey. This study illustrates the power of meaningful relationships in breaking down artificial categories and in bringing about important change with regards to the perceptions and attitudes of individuals towards community engagement. It is hoped that the data generated through this study will assist in recruiting and retaining more literacy volunteers through feedback to the NGO. In this way more children will be assisted to enhance their literacy competencies, from which they can build and achieve.

- Description: Mathematics is the foundation for the economic and technological development of any nation. It has been asserted that Mathematics is expected to help in accelerating social, economic and technological progress of any society. Performance of this subject is very important and there are different types of learners; such auditory, visual, and kinesthetic. Auditory learners appreciate listening to the teachers and sit down close to the teachers in class. Visual learners like to see things physically during teaching. They learn by materials like charts, graphs, and pictures. Kinesthetic learners learn by doing. Students can prefer one, two, or three learning styles; all these are subject to the availability of instructional materials. The Primary school level is very important in any educational system and any lack at this level would permeate to other levels of the educational system. Hence, this thesis examines the Learning Styles, Availability, and Utilization of Instructional Materials as Correlates of Grade 6 Learners’ Mathematics Performance in Buffalo City. The study adopted the positivist paradigm and employed the quantitative approach in investigating the phenomenon. The thesis made use of correlational research design as it attempted to find out the effects of learning styles and instructional materials on learners’ performance in Mathematics. Stratified sampling was used to select participants. Stratified sampling is a process of dividing the sample frame into strata to obtain relatively homogenous subgroups; this gave us 1225 Grade 6 learners selected across 35 schools in Buffalo City as the sample of the study. Three instruments which are Students’ Learning Styles Scale (SLSS), Availability and Utilization of Instructional Materials Inventory (AUIMI), and Mathematics Achievement Test (MAT) whose reliability co-efficient are; 0.87, 0.78 and 0.89 respectively. The data collected were analysed using descriptive and inferential statistics. The findings of the study revealed among others; students learning style (visual, auditory, and kinesthetic) have a significant relationship on Grade 6 learners Mathematics performance (B=-.113, t=-3.886, p<0.05). Students learning style (∆R2=.012, ∆F (1, 1223) = 5.047, p < 0.05) emerged as the best predictor of Grade 6 learners Mathematics performance in Buffalo City, while the availability and utilization of instructional materials (∆R2 = .000), ∆F (1,223) = .018, P > 0.05), and gender (∆R2 = .000, ∆F (1,1223) = .036, p>0.05) emerged as better predictors. The study further iv revealed that, Grade six learners with visual learning style ( = 13.242, SD = 5.565) had the best performance in Mathematics at Buffalo City, followed by learners with auditory learning style ( = 12.996, SD = 3.883), and learners with Kinaesthetic learning style ( = 11.525, SD =3.800). The study concluded that one of the most fundamental issues to consider in improving Mathematics performance is the understanding of the learners’ learning styles and effective use of appropriate instructional materials for teaching Mathematics.

- Description: Mathematics is the foundation for the economic and technological development of any nation. It has been asserted that Mathematics is expected to help in accelerating social, economic and technological progress of any society. Performance of this subject is very important and there are different types of learners; such auditory, visual, and kinesthetic. Auditory learners appreciate listening to the teachers and sit down close to the teachers in class. Visual learners like to see things physically during teaching. They learn by materials like charts, graphs, and pictures. Kinesthetic learners learn by doing. Students can prefer one, two, or three learning styles; all these are subject to the availability of instructional materials. The Primary school level is very important in any educational system and any lack at this level would permeate to other levels of the educational system. Hence, this thesis examines the Learning Styles, Availability, and Utilization of Instructional Materials as Correlates of Grade 6 Learners’ Mathematics Performance in Buffalo City. The study adopted the positivist paradigm and employed the quantitative approach in investigating the phenomenon. The thesis made use of correlational research design as it attempted to find out the effects of learning styles and instructional materials on learners’ performance in Mathematics. Stratified sampling was used to select participants. Stratified sampling is a process of dividing the sample frame into strata to obtain relatively homogenous subgroups; this gave us 1225 Grade 6 learners selected across 35 schools in Buffalo City as the sample of the study. Three instruments which are Students’ Learning Styles Scale (SLSS), Availability and Utilization of Instructional Materials Inventory (AUIMI), and Mathematics Achievement Test (MAT) whose reliability co-efficient are; 0.87, 0.78 and 0.89 respectively. The data collected were analysed using descriptive and inferential statistics. The findings of the study revealed among others; students learning style (visual, auditory, and kinesthetic) have a significant relationship on Grade 6 learners Mathematics performance (B=-.113, t=-3.886, p<0.05). Students learning style (∆R2=.012, ∆F (1, 1223) = 5.047, p < 0.05) emerged as the best predictor of Grade 6 learners Mathematics performance in Buffalo City, while the availability and utilization of instructional materials (∆R2 = .000), ∆F (1,223) = .018, P > 0.05), and gender (∆R2 = .000, ∆F (1,1223) = .036, p>0.05) emerged as better predictors.

- Description: Professional psychology in South Africa has experienced numerous transformations since its tainted historical affiliation with the apartheid regime. However, despite the profession’s attempts to respond to the burgeoning mental health needs of the country, psychologists in South Africa continue to be confronted by a number of challenges within the professional field. International research suggests that early career psychologists, in particular, experience further challenges in adjusting to new professional careers. Considering the dearth of research on this topic within local literature, the aim of this study was to gain an in-depth understanding of the lived professional experiences of recently qualified clinical and counselling psychologists in South Africa, following training. An interpretive phenomenological method was employed to investigate the fundamental early career professional experiences of participants, as well as the meanings participants attributed to these experiences. Four participants were recruited using purposive sampling. Data was collected through the use of semi-structured, one-on-one, Skype interviews, and the interview data were analysed using interpretative phenomenological analysis. The study revealed four super-ordinate themes, including: (i) Training as a ‘rite of passage’; (ii) Expectations for a professional future; (iii) Professional psychology: Entering the work space; and (iv) Future directions. The findings suggest that clinical and counselling psychologists’ experiences as recently qualified professionals in South Africa are both positive and negative, with the overall experience being positive. Emerging themes suggest that early career psychologists are faced by a number of personal and professional challenges on entering the work place. Furthermore, findings suggest that the early career experiences of recently qualified clinical and counselling psychologists in South Africa might not necessarily be due to personal choice, but rather due to greater systemic factors, such as limited available posts, maladministration, the devalued status of mental healthcare in comparison to other healthcare concerns in the country, an unresponsive marketplace and limited efforts by government to accommodate psychologists in different contexts

- Description: The margin of the Southern Africa continent harbours the history about the fragmentation and separation of Gondwana in its basins. The integration of onshore and offshore geology is of primordial importance to understand the complete geological history and evolution of the southern African border. The study focuses on the Gamtoos Basin, where the sediment deposits on the onshore portion are generally unfossiliferous and therefore difficult to correlate with the offshore portion of the basin. In an attempt to do this, several datasets were integrated such as old 2-D seismic reflection data and borehole wells. This data, acquired by SOEKER in the 1970s was purchased from the Petroleum Agency of South Africa (PASA). Some data reprocessing involved digitization and conversion of the old seismic data from TIF format to SEG-Y format. Conventional seismic stratigraphic method (Mitchum, JR, et al., 1977) was used to identify seismic discontinuities and remarkable stratigraphic surfaces and units based on reflection configurations and facies characteristics, and ages of these surfaces were provided by well data. Seismic interpretation was first done on printed seismogram papers, and then integrated into the ‘Kingdom Suite’ software to ensure coherency at all crossing lines. Isochron and Isopach maps (using QGIS, Mirone and tools such as GMT) were created. The first results, allow us to estimate for the first time a precise age calibration of onshore deposit. Furthermore, the delimitation in 5 second-order seismic sequences along the Gamtoos Basin suggest a link between different basin filling dynamics and kinematic phases related to the opening of the Indian and Atlantic Oceans along the southern Africa margins. The study shows that the Gamtoos Basin is an essential area linking the geological histories of both East and Western parts of the Southern Africa continent.

- Description: This thesis explores the use of a postmodernist aesth etic in Alain Mabanckou’s oeuvre, namely Blue White Red, African Psycho, Broken Glass, Memoirs of a Porcupine, Black Bazaar, Tomorrow I’ll Be Twenty, The Lights of Pointe-Noire, and Black Moses. In particular, I show how and why this Afrodiasporic author localises strategies associated with Western postmodernist writing in an African postcolonial context. My central argument is that if postmodernism is a critique of modernity in the West, then it must also be a respon se to enforced modernity in the African postcolonial context. In mounting this argument, I conduct a close reading of Mabanckou’s novels from within the theoretical frameworks of postmodernism and postcolonialism. I demonstrate that Mabanckou’s writing adu mbrates the possibility of a postcolonial postmodernism. Since he is a French-Congolese citizen, his writing evinces aesthetic glocalisation. That is, as a postcolonial writer, he conceives of, and inflects, postmodernism differently from a Western writer, for his experiences of and responses to modernity differ from the latter’s. Far from replicating a politics of disillusionment and despair that informs, even characterises, Western postmodernist fiction, Mabanckou invests hi s African postcolonial writing with a politics of decolonis ation which problematises the effects of enforced modernity. Postmodernism, in other words, accords Mabanckou an ambivalent position from which he interrogates both Western modernity and its African version. Significantly, in this regard, Mabanckou’s writing presents both an extension of and a departure from the pioneering influence of the first generation of African writers such as Chinua Achebe, Ngugi wa Thiong’o, and Wole Soyinka.

- Description: Background: The global, exponential growth in the elderly population and increased longevity has been well documented. South Africa has the highest proportion of older population in sub-Saharan Africa. Empirical research is lacking on the efficacy of exercise interventions for the elderly to prevent fall risk and increase independent living associated with quality of life. Maintenance of muscular strength of the lower body is important to compensate for various physiological deficits due to the ageing process. Aim: The aim of the study was to determine the effects of an eight-week lower extremity strength training intervention on balance and postural control in female elderly, aged 65 years and older, living in a high socio-economic, urban, residential area in Nelson Mandela Bay in the Eastern Cape region of South Africa. Design and Methods: A true-experimental, pre-test, post-test study design, was used with a comparative experimental and control group. A total number of 21 participants met the inclusion criteria and were randomly assigned to an experimental or control group. The experimental group participated in an eight-week strength training intervention, attending exercise sessions, twice a week. Peak isometric strength of the knee flexors/extensors, adductors/abductors of the hip, and plantar / dorsi-flexors of the ankle were assessed post-intervention, using the FET2 handheld dynamometer. Balance was assessed by means the displacement of centre of pressure during the limits of stability and the ellipse area for postural sway assessment on a Kistler force plate, post-intervention. Medial/lateral displacement of centre of pressure and the mean velocity while descending a self-designed, two-step stair case, were determined after the intervention by measures obtained from a Kistler force plate. Descriptive statistics were calculated for measures of central tendency including means standard deviations. T-scores were used to standardise results obtained. Non-parametric, inferential statistics were used to determine the statistical significance of the results. The Wilcoxon matched pairs test and the Mann-Whitney U tests determined the significance of within group comparisons. Statistical significance was set at p<0.05. Spearman rank order correlations were used to measure the strength of associations Results: Lower extremity isometric strength in musculature around the hip, knee and ankle joints, as well as postural sway in a stationary position with eyes opened, have improved significantly after an eight-week resistance training Programme. Improvements in balance has been indicated by limits of stability in the postural sway stance with eyes closed, and dynamic balance during stair descending, were both not significant. Conclusion: The importance of physical interventions to enable the elderly in living a healthy and independent lifestyle should be promoted in all settings. Muscle strength gains and postural sway improvements could have been attributed to neural adaptation and calls for further investigation into the efficacy of strength training over longer durations. The relevance of incorporating stair negotiation as a functional activity of daily living should potentially be included in exercise Programmeprescription by biokineticists, as insufficient control of dynamic balance has been reported to increase fall risk.

- Description: The production of metal mirrors and critical components for optical devices and aerospace application requires extreme high accuracy and outstanding surface quality. Thus, to achieve such high dimensional accuracies, they are being mainly produced through ultra-high precision machining. Aluminium alloys have been used in the production of components for optics application as well as spaceborne for so many years but with the advancement in technology and demands for a superior material, a new modified grade of aluminium was developed by a rapid solidification process. These grades exhibit a much better mechanical and physical properties while having a finer microstructure. The only downside is the limited research in the correlation of surface roughness and reflectance when single point diamond turned. In this study, rapidly solidified aluminium RSA 905 were used to investigate the effect of varying the cutting parameters on the machined surface finish and its corresponding surface reflectance. The cutting parameters were cutting speed, feed rate and depth of cut. The surface roughness was measured using Taylor Hopson PGI Profilometer while the reflectance factor was measured by using VERTEX 80v Spectrometer. The results were used to develop two predictive models namely; response surface and artificial neural network which have indicated a very high accuracy to the experimental measurements. Finally, the results were very promising for the diamond turning of RSA 905 where it has achieved a very low values of surface roughness and high reflectance in the visual range without the need of any additional production/fabrication steps and to ensure that bi-metallic binding does not take place in extreme low temperatures. Therefore, RSA 905 is a very promising material for optical applications in the visual spectrum.

- Description: This research falls under the general themes of macro-locational determinants and motives of Foreign Direct Investment (FDI) and the challenges faced by FDIs. Specifically, the research focuses on macro-locational determinants of FDI and the motives of Chinese FDI in Cameroon, and the challenges faced by Chinese FDI in Cameroon. This research is motivated by China’s interest in African countries as well as the reciprocal interest in Chinese FDI by African countries, especially Cameroon. While various FDI theories and previous empirical studies indicate that macro-locational determinants of FDI constitute a country’s principal comparative advantage to attract FDI, there is still no universally acceptable set of macro-locational determinants of FDI. Furthermore, some empirical studies assert that Chinese FDI does not follow conventional FDI theories or western approaches to FDI, especially when investing in African countries. It is suggested that some widely accepted macro-locational determinants of FDI are frequently ignored by Chinese FDI. While FDI theories identify four motives for FDI (resource-, market-, efficiency-, and strategic asset-seeking) as the main motives for investing in a foreign country, the motives for Chinese FDI, especially in Africa, have been questioned by some scholars, the media and politicians, due to the significant but seemingly counterintuitive investments made by Chinese state-owned FDI in politically unstable resource-rich African countries. Furthermore, differences in the motives of Chinese privately owned and state-owned firms identified in previous empirical studies have raised concerns, particularly regarding the motives of state-owned Chinese firms in Africa which suggest a stance of neo-colonialism by Chinese state-owned FDI. The research aims to identify the significant macro-locational determinants of Chinese FDI in Cameroon, to provide clarity on the motives of Chinese FDI and to identify the challenges faced by Chinese FDI in Cameroon. To achieve the aim of this research, hypothetical relationships based on FDI theory and previous empirical research were formulated between Chinese FDI and the proposed macro-locational determinants of FDI and the four identified motives of FDI. In this research, a positivist research paradigm using quantitative methods was followed. Accordingly, the research design and methodology was underpinned by the positivist paradigm. A descriptive and analytical survey methodology was utilised, using both primary and secondary data sources. Secondary data was collected from reliable and credible databases for the period 2004 to 2018 to generate a time series to test the hypothetical relationships pertaining to the macro-locational determinants of Chinese FDI in Cameroon. To test the hypothetical relationships pertaining to the motives of Chinese FDI and to identify the challenges of Chinese FDI in Cameroon, primary data was collected by means of a questionnaire using convenience and snowball sampling techniques. The validity of the findings on the macro-locational determinants of FDI was confirmed through unit root and cointegration tests. Confirmatory Factor Analysis (CFA) and Cronbach’s alpha coefficients were used to ensure the validity and reliability of the findings on the motives of FDI. To assess the hypothetical relationships on the motives for Chinese FDI, the hypothetical relationship on the macro-locational determinants of FDI was determined using Ordinary Least Square (OLS) regression, t-tests, one-way ANOVA, descriptive statistics and logistic regression. In addition, descriptive statistics were used to analyse the data on the challenges of Chinese FDI. The findings indicated that the main macro-locational determinants of Chinese FDI in Cameroon included market size, political risk, limited trade openness, real effective exchange rate, interest rate and human capital. The findings also indicated that market-seeking constitutes the main motive of privately owned Chinese FDI in Cameroon. The findings also indicated that the top four challenges faced by Chinese FDI in Cameroon include corruption, the ambiguity of the legal system of Cameroon, the difficulty to negotiate with government and privatisation officials and high levels of taxes. The findings of this research serve as a test of theory, given that they determine whether the macro-locational determinants identified from FDI theories are also significant macro-locational determinants of Chinese FDI. Furthermore, the findings have the potential to assist in policy formulation aimed at encouraging Chinese FDI into Cameroon. The findings could also assist the Cameroonian government to allocate national resources efficiently by prioritising identified macro-locational determinants. The findings provide clarity on the motives of Chinese FDI in Cameroon and could assist the government to negotiate better deals that may enable Cameroon to benefit optimally from Chinese FDI.

Specifically, the research focuses on macro-locational determinants of FDI and the motives of Chinese FDI in Cameroon, and the challenges faced by Chinese FDI in Cameroon. This research is motivated by China’s interest in African countries as well as the reciprocal interest in Chinese FDI by African countries, especially Cameroon. While various FDI theories and previous empirical studies indicate that macro-locational determinants of FDI constitute a country’s principal comparative advantage to attract FDI, there is still no universally acceptable set of macro-locational determinants of FDI. Furthermore, some empirical studies assert that Chinese FDI does not follow conventional FDI theories or western approaches to FDI, especially when investing in African countries. It is suggested that some widely accepted macro-locational determinants of FDI are frequently ignored by Chinese FDI. While FDI theories identify four motives for FDI (resource-, market-, efficiency-, and strategic asset-seeking) as the main motives for investing in a foreign country, the motives for Chinese FDI, especially in Africa, have been questioned by some scholars, the media and politicians, due to the significant but seemingly counterintuitive investments made by Chinese state-owned FDI in politically unstable resource-rich African countries. Furthermore, differences in the motives of Chinese privately owned and state-owned firms identified in previous empirical studies have raised concerns, particularly regarding the motives of state-owned Chinese firms in Africa which suggest a stance of neo-colonialism by Chinese state-owned FDI. The research aims to identify the significant macro-locational determinants of Chinese FDI in Cameroon, to provide clarity on the motives of Chinese FDI and to identify the challenges faced by Chinese FDI in Cameroon. To achieve the aim of this research, hypothetical relationships based on FDI theory and previous empirical research were formulated between Chinese FDI and the proposed macro-locational determinants of FDI and the four identified motives of FDI. In this research, a positivist research paradigm using quantitative methods was followed. Accordingly, the research design and methodology was underpinned by the positivist paradigm. A descriptive and analytical survey methodology was utilised, using both primary and secondary data sources. Secondary data was collected from reliable and credible databases for the period 2004 to 2018 to generate a time series to test the hypothetical relationships pertaining to the macro-locational determinants of Chinese FDI in Cameroon. To test the hypothetical relationships pertaining to the motives of Chinese FDI and to identify the challenges of Chinese FDI in Cameroon, primary data was collected by means of a questionnaire using convenience and snowball sampling techniques. The validity of the findings on the macro-locational determinants of FDI was confirmed through unit root and cointegration tests. Confirmatory Factor Analysis (CFA) and Cronbach’s alpha coefficients were used to ensure the validity and reliability of the findings on the motives of FDI. To assess the hypothetical relationships on the motives for Chinese FDI, the hypothetical relationship on the macro-locational determinants of FDI was determined using Ordinary Least Square (OLS) regression, t-tests, one-way ANOVA, descriptive statistics and logistic regression. In addition, descriptive statistics were used to analyse the data on the challenges of Chinese FDI. The findings indicated that the main macro-locational determinants of Chinese FDI in Cameroon included market size, political risk, limited trade openness, real effective exchange rate, interest rate and human capital. The findings also indicated that market-seeking constitutes the main motive of privately owned Chinese FDI in Cameroon. The findings also indicated that the top four challenges faced by Chinese FDI in Cameroon include corruption, the ambiguity of the legal system of Cameroon, the difficulty to negotiate with government and privatisation officials and high levels of taxes. The findings of this research serve as a test of theory, given that they determine whether the macro-locational determinants identified from FDI theories are also significant macro-locational determinants of Chinese FDI. Furthermore, the findings have the potential to assist in policy formulation aimed at encouraging Chinese FDI into Cameroon. The findings could also assist the Cameroonian government to allocate national resources efficiently by prioritising identified macro-locational determinants. The findings provide clarity on the motives of Chinese FDI in Cameroon and could assist the government to negotiate better deals that may enable Cameroon to benefit optimally from Chinese FDI.
