- Description: This study examines pre-termination of pregnancy (PTOP) counselling, focussing on issues of language and access, and sociocultural influences. This research examines linguistic and cultural aspects of communication between healthcare providers and clients in PTOP contexts. The overarching aim of this research was to identify patterns that indicate miscommunication and to propose ways to bridge any linguistic and cultural gaps. This research examine how social norms related to turn taking guide healthcare providers - clients interaction and how the clients respond to advice offered during the counselling sessions. The study provides an indepth understanding of linguistic and cultural barriers in public healthcare, and further emphasizes the need for implementation of support systems for cross-cultural and effective patient-centred communication in healthcare. The findings in this study are thatpresent that miscommunication occurs within intercultural and intra-cultural medical encounters. Excessive use of medical terminology causes communication difficulties. Clients often provide a positive response to indicate that they understand what the healthcare provider is communicating. Clients sometimes respond positively out of politeness. This practice is common in some cultures; it often occurs when the recipient is interacting with a figure of authority or someone of higher positioning. It is found that healthcare provider’s value systems sometimes have an impact on their professional conduct, influencing the type of PTOP counselling provided to clients. Sometimes the language and communication barriers have a negative impact on the quality of care/PTOP counselling. This study argues that healthcare provider’s communication styles and value systems influence PTOP counselling. Healthcare providers have the power to control the medical discourse; their turns at talk influence those of clients. The manner in which the nurses and counsellors address the clients elicits a certain response. This study thus suggests that healthcare providers need to improve their communicative skills, be mindful of their position as power holders and adopt a patient-centred approach, which is crucial for clinical and cultural competence.

- Description: This short composition portfolio comprises 40% of the requirements for the Master of Music Degree in performance and composition at Rhodes University. In addition to the music presented here, I played two public exam recitals of 70 minutes each. While I played piano as a child, my main instrument during my BMUS studies at the University of Cape Town (2004-2007) was the saxophone. In 2010 I was diagnosed with Polymyositis(an auto-immune desease) which particularly affected my breathing and therefore my ability to play the saxophone. For this reason I opted to play my recitals on the piano. The first recital focused on interpretations of Swing Era, Bebop and post-Bebop standards such as: Someday my prince will come, What is this thing called love, In your own sweet way, Eternal Triangle, Recordame, Peace, Dolphin Dance, Caravan and Some other blues. The second recital comprised of seven original compositions that were presented in trio, quartet and quintet settings.

- Description: In Zambia, ‘contemporary art’ (as a category constructed by the European-dominated international art world), was introduced by the European settler community and continued within its preserve, remaining largely inaccessible to the indigenous community of Africans until Zambia’s independence in 1964. This thesis traces the integration of Africans into the contemporary art community and attributes the process, in part, to a small group of artists of European descent who played a significant role in engaging with Zambians, working side by side with them, subsequently influencing their art production and implicitly shaping the ways in which ‘Zambian’ art ‘ought to’ look for decades to come. The research traces the early days of contemporary art practice in Zambia to the Lusaka Art Society and Art Centre Foundation that was founded and run by an all-settler group of formally trained artists with a particular inclination towards sculpture and painting. In the wake of the integration however, art production in the formalist manner was further proliferated by the European diplomatic community which would also go as far as dictating artistic subject matter. This thesis argues that the Eurocentric and pre-eminently formalist approach to contemporary art has cost Zambian artists an international presence. I submit that the few instances where contemporary Zambian art practice has penetrated the ‘global art’ scene or caught the attention of international curators is due to artists adopting more radical conceptual approaches to art production, often creating tensions with local viewers. This thesis also examines conceptualism in contemporary Zambian art practice and examines the inequalities of the ‘global art’ world. I argue that conceptual art, although not generally accepted on the Zambian art scene, has played a vital role in helping Zambian artists enter the global art world, albeit modestly.

- Description: The micro-blogging site Twitter, and the social networking site Facebook, are playing a key role in facilitating active political expression in the form of demonstrations against high rates of unemployment, poverty, rampant government repression and corruption. Twitter use in Zimbabwe is very vibrant and it even has its own name, ‘Zwitter.’ Zimbabwe has a closed legacy news media which are highly restricted, and most of the major news outlets are controlled by the state. Another limiting factor to any meaningful practice of deliberative democracy through the media and town hall debates is the intolerance of the ruling party ZANU-PF in dealing with dissenting voices. Thus in Zimbabwean politics, it can be argued that the internet has liberated political debates that have been suppressed and digital media is central to political and social deliberation. This study examines whether there are conversations, turn-taking, and dialogues-all features of deliberations- on the @263Chat Twitter platform which is used as a case study. Qualitative content analysis and interviewing were used to collect the data. The preliminary results of the research show that citizen-led engagements, which are facilitated by @263Chat, have brought to the fore the covert potential of social media platforms to drive political participation and deliberation.

- Description: The recent growth in the unsecured lending market and the bankruptcy of African Bank Investments Limited have brought to light concerns regarding credit extension and the level of household indebtedness in South Africa. This study seeks to investigate the relevant aspects of credit extension in both the secured and unsecured lending markets by firstly analysing contemporary literature and then conducting a more formal empirical analysis. A VAR model is estimated to examine the effects household disposable income and interest rates have on the level of household debt in South Africa for the period 1995Q1-2015Q3. The empirical results indicate that there is no significant deterministic relationship between household disposable income and household debt. However, the results show that such a relationship does exist between interest rate and household debt. Finally, impulse response functions obtained from the VAR estimation are examined which indicate that both shocks too household disposable income and interest rates effect the level of household debt, but that this effect returns to equilibrium within six periods.

- Description: Land and inanimate resources constitute the most dominant theme in the history of Zimbabwe. Questions around land, the environment and natural resources in Zimbabwe have recently focused on the contentious Fast Track Land Reform Programme of the year 2000. Yet Zimbabwe’s land questions are not limited to this contentious land reform programme. Among Zimbabwe’s contentious land questions are those of the Tonga people, displaced in the 1950s to pave way for the construction of the Kariba dam. These people have faced further displacement through conservation-induced restrictions on land and environmental resource use, particularly in the Zambezi Valley and specifically in areas where they were relocated after the dam-induced displacement. This thesis examines the ways in which the Tonga people of Mola in NyamiNyami District have framed their present environment to place imprints in Mola from their Zambezi landscape and to convert Mola into a landscape of home and belonging. It looks at how the Tonga in Mola use these narratives of home and belonging to claim and contest access to environmental resources in the face of an unfettered regime of displacement and restricted environmental resource use. These narratives of home are located within the context of memories of the history of Kariba dam-induced displacement and present-day environmental conservation regime practices. The thesis frames the case study of the Tonga in Mola analytically through the use of mainly a social constructionist theory of landscape and, less so, with reference to the Bourdieusian concept of habitus. It uses qualitative research methods in doing so. The thesis reveals that, for the Tonga of Mola, the environment is a complex mix of physical space (natural environment) and non-physical entities that include ancestors. Because of this, the Mola Tongan environment is multifaceted and this entails landscape as lived reality and a sacred space. The ancestors, referred to locally as banalyo gundu (meaning ‘owners of the land’), constitute a key way in which the Tonga claim belonging to Mola, Lake Kariba and the Zambezi Valley escarpment. The thesis also identifies and highlights the phenomenon of a dual belonging (attachment to two places), namely Mola and the place from which they were displaced. This exists despite the many years since their displacement for the construction of Kariba. Based on their understandings of landscape, the Tonga of Mola construct notions of belonging and entitlement to Mola and Lake Kariba that exclude and include others at the local and national levels. Overall, belonging in Mola is presented and practised as a discursive, socially constructed phenomenon that exists at local and national levels.

- Description: Dance has numerous benefits for emotional well-being. For young people specifically it can serve as a prosocial activity where they can engage in a purposeful activity, in a safe space with consistent boundaries and discipline, while surrounded by peers, teachers and positive role models. Recreational spaces that allow young people to feel safe and express themselves is especially important in low socioeconomic areas where there are limited resources and exposure to heightened levels of crime as young people may be less likely to engage in negative behaviours when they have access to alternative, positive activities. This research aimed to explore the lived experiences of a group of young people who participate in dance classes at a community dance project in the Western Cape. The sample group consisted of four young people between the ages of 16 and 20. Semi-structured interviews were conducted with the participants and the interviews were analysed using interpretative phenomenological analysis. Three major themes emerged from the data, namely 1) My exposure to dance - The impact of context, 2) What motivates me to continue attending classes - The fulfilment of the three basic psychological needs, and 3) How does dance make me feel - The experience of emotional well-being through dance. The discussion of the findings yielded many similarities between the experiences of the participants and the relevant literature. Further, it appears that all four participants experience the satisfaction of the three basic psychological needs (competence, autonomy and relatedness) at the centre. This may serve as a motivator to continue attending classes as well as contribute to sustained eudaimonic wellbeing. Recommendations include further studies being conducted with groups of young people engaging in dance projects in different socioeconomic contexts and in different parts of South Africa. This could give us a more rounded understanding of how people young people experience dance class and how it contributes to emotional well-being. Further research could also be conducted with recreational projects that offer other activities in under-resourced areas in order to better inform the development of such recreational activities.

- Description: Population density may exert changes in a variety of behavioural and physiological characters in animals. However, the effects of density-dependence and dispersal are poorly studied in subterranean rodents due to the difficulties involved in observing such effects in wild populations. Using the cooperative breeding Damaraland mole-rat (Fukomys damarensis) as a model species, the effects of population density on body size, growth rates, group size, recruitment, philopatry and dispersal were investigated at two sites (one with low density and one with high density) in the Northern Cape of South Africa. Group size, litter size and the probability of recapture were independent of population density. However, individual body size, recruitment, dispersal rate and dispersal distance were density-dependent. Individuals were significantly larger, juveniles exhibited a significantly higher growth rate, and juvenile recruitment was significantly greater when population density was low. At higher densities, significantly more individuals were lost between capture events which may be indicative of increased rates of dispersal. Mean dispersal distances in mole-rats were reduced at higher densities and increased at lower densities. While both sexes dispersed equally, males were significantly more likely to join an established colony and females created new burrow systems. In addition, four times as many single females were found when population density was low. The apparent differences in the study populations may be attributed to variable annual rainfall or food availability. The greater annual rainfall at the high-density site may provide better habitat conditions and therefore result in an increase in the population density and an increased dispersal rate due to the relaxed ecological constraints such as reduced energetic costs to burrowing. However, the larger body size found at the low-density site may indicate that the available food at that location is of better quality. This study revealed that mole-rats were able to disperse over 1km and therefore a much larger study area would be required in capture-mark-recapture studies to ensure the recapture of the majority of dispersers. Lastly, a surprising find of this study was that females may survive a solitary existence for over two years while awaiting the arrival of a mate.

- Description: This study builds on South African cross-cultural research which highlights the need for careful stratification of normative samples for quality of education and geographical location. The aim of the present study was to produce an expanded set of preliminary norms for learners in the disadvantaged schools of the peri-urban areas of the Eastern Cape, Grahamstown, on the Vassiliou Mathematics Foundation Phase Test (VASSI) and Vassiliou Mathematics Proficiency Test (VASSI), respectively. The test was administered to Grade 1-6 learners in four different schools all within Joza location, Grahamstown. For the learners’ convenience the tests were translated into isiXhosa, the translations were provided together with the original English questions. Archival data collected by honours students was also incorporated in this study. The total number of participants was N=724 which was comprised of 147 grade 1s, 123 grade 2s, 117 grade 3s, 128 grade 4s, 113 grade 5s and 96 grade 6s. Norm-referenced criterion was used in analysing the data. The results of this study are in accordance with those purporting the low performance of disadvantaged learners on the school subject, mathematics. Stanines for the various grades (Grade 1 to 6) were calculated and are presented in the study. This study has demonstrated that although gender, language and other ethnic variables have an impact on mathematics performance, quality of education and socioeconomic status have a significant effect. Further research is needed on the effect of quality of education and socioeconomic status on learners in disadvantaged schools on this test in particular.

- Description: Of the eight Millennium Development Goals (MDGs) established in 2000 by the World Health Organisation, Millennium Development Goals 5 aimed at improving maternal health by addressing the high maternal mortality rate and increasing universal access to reproductive health by 2015.Adolescent pregnancy contributes to maternal, perinatal and infant mortality and also worsens the empowerment of young girls by negatively affecting their physical, educational, social, and economic development.This is a pressing public health concern in South Africa. The reduction of adolescent pregnancy is vital for achieving the sustainable human, health social and economic development of society at large. Culturally sensitive interventions to prevent adolescent pregnancies not only integrate the communities' norms, values, practices and behavioural patterns into the intervention's design and implementation but also the historical, social and economic contexts in which they exist. Progress has been made on the research on health promotion and education in South Africa; however communities are often not consulted on the design and conduct of health promotion research projects.The aim of the study was to develop and implement culturally sensitive and appropriate health promotion activities for the prevention of adolescent pregnancy in Grahamstown, Glenmore and Ndwayana communities in the Eastern Cape, South Africa.Two community based organisations and community care workers associated with them participated in this Community Based Participatory Research using the PEN-3 cultural model. The first phase of this study involved semi-structured interviews carried out with 14 community care workers to identify factors and consequences of adolescent pregnancies in their respective communities. The audio-recorded interviews were transcribed and coded using NVivo® 2010 software. The PEN 3 cultural model was adopted in the studyto address the socio-cultural factors contributing to adolescent pregnancy in the communities. The second phase involved a series of interactive workshops with CCWs for a participatory development of the facilitator's manual. Responses from CCWs informed the design of this study's intervention strategies. A facilitator's manual was developed to implement health promotion intervention, leading to the third phase of this study. The guided implementationof the health promotion intervention for the prevention of adolescent pregnancy was carried out over a period of 14 months and evaluated in the final phase of the study. The facilitator's manual was modified based on feedback fromCCWs, on possible improvements and cultural appropriateness. Readability testing guided the final modification of the manual. According to the community care workers, there were a number of adolescents who fell pregnant in their communities each year. The CCWs identified the influence of family members, friends and other stakeholders as contributory factors to adolescent pregnancy. They identified the lack of parental support in informing and educating adolescents about sexual health. Adolescents themselves lacked the maturity to recognise the risks and consequences of adolescent pregnancy. The negative perceptions of contraception in the community were discouraging contraceptive use amongst the adolescents. However, the results showed that enablers such as home and school visits done by the community care workers can be utilised to prevent adolescent pregnancy. Other factors included lack of health promotion materials and activities with information about preventing of adolescent pregnancy, and if available, the material is in English, that the adolescents may not comprehend. Socio-economic factors such as poverty, the Child Support Grant, cross generational relationships and coerced sex further contributed to adolescent pregnancy in the communities.CCWs identified the need for a more comprehensive health promotion intervention to prevent of adolescent pregnancy. A facilitator's manual addressing the prevention of adolescent pregnancy was developed and modified through a series participatory workshops with the community care workers.The facilitator's manual was used by CCWs to conducthealth promotion activities encouraging the prevention of adolescent pregnancies within the community's clinics, schools and during home visits. Community based participatory research methods and the PEN-3cultural model were used to develop this culturally sensitive and community specific adolescent pregnancy intervention for and by the CCWs. The participatory development of the facilitator's manual and the regular interactive workshops with the CCWs were strengthened by embedding this project into the development programs of the two non-governmental organisations contributing to sustainable development programs for women and children.

- Description: Distinct day-night changes in ambient light are recognised as an important driver of animal activity patterns, with predictable changes to the structure and composition of animal communities between day and night. While day-night variation in the structure of animal communities has been well researched for terrestrial organisms and shallow marine fish communities around the world, there has been limited research of this type conducted on South Africa’s rocky reef fish communities. Consequently, we have a poor understanding of how nocturnal reef fish communities are structured and the day-night activity patterns of species inhabiting both shallow (10-30m) and deep-aphotic (55-100m) reefs. This research was conducted at two warm-temperate South African rocky reefs situated in Algoa Bay. The importance of natural ambient light in shaping the distribution of reef fish communities at shallow and deep-aphotic reef sites was demonstrated using baited remote underwater stereo-video systems (stereo-BRUVs). Distinct day and night fish communities were sampled at shallow and deep-aphotic reef sites. These differences were driven by significant changes in species richness (p < 0.001), species abundance (p < 0.001) and community composition (p < 0.001). These shifts appeared to be driven by day-night activity patterns that were the result of increased detectability of certain species at either day or night. The majority of species belonging to the family Sparidae showed evidence of strict diurnal activity, with their activity being further restricted to shallow reefs. These species showed evidence that they may enter micro-habitats within the reef at night. Similar activity patterns were shown for other top predatory teleost species and low level consumers, with substantial reductions in abundances, or no recordings at night throughout this study. Shallow reefs at day harboured the most diverse fish community. It is therefore hypothesised that this habitat was associated with conditions that offered improved access to resources for many visual species. In addition, the diverse community inhabiting shallow reefs at day is associated with a high risk of negative interspecies interactions, such as competition and predation. It is hypothesised that the biotic conditions associated with shallow reefs at day drove three movement patterns identified in this study; Pagellus bellottii natalensis showed evidence of movement onto shallow reefs at night from adjacent sandy flats, while Pterogymnus laniarius and Squalus sp. 1 showed evidence of movement onto shallow reefs at night from the deep- aphotic reefs that remain dark throughout the diel cycle. It is further hypothesised that other species which showed evidence for nocturnal activity, i.e. Galeichthys ater, Eptatretus hexatrema and Haploblepharus edwardsii, may enter sheltered micro-habitats within the reef during day light hours. These findings have highlighted the complex patterns that have evolved within marine fish to allow multiple species to coexist and exploit productive reef ecosystems by partitioning resource use and activity patterns at day or night, between depth zones and habitat types.

- Description: This research assesses the drivers of sustainability disclosure in Liberty Holdings. The relevance of reporting on sustainability is growing for both listed and non-listed companies in South Africa. However, many companies many companies still coming to terms with reporting process, although others are doing exceptionally well. Liberty Holdings is one of the insurance organisations that has continuously improved their sustainability reporting and disclosure of their sustainability issues, in a sector that previously perceived such concerns as low on their agenda, due to the perception that they had a low impact on the sector. The research findings reveal that the process of sustainability disclosure in Liberty Holdings is driven by several elements that are strategically linked and are aligned to the core strategy of the organisation. The findings also indicate that in order to understand and implement viable sustainability processes, the processes must be embedded in a well-informed sustainability strategy that is aligned with this core strategy.

- Description: Early stage fishes (larvae and early juveniles) were collected from an array of shallow water (±1.5m) habitats on the warm-temperate southern Angolan coastline between June 2014 and June 2015. This study, the first assessment of the early stages of coastal fishes in Angola, provides important new understanding of non-estuarine shallow water nursery habitat use by coastal fishes from the region. In total, 51 species from 18 teleost families were observed. The exposed surf zone was dominated by postflexion larvae, while the moderately exposed beach and sheltered bay were dominated by early juveniles. Both fish density and diversity peaked in the wet season (Feb – Apr 2015) for all habitats, attributed to the influx of summer spawning species. Diplodus sargus dominated catches from the exposed surf zone, and the timing of observations supports the growing consensus that sparid spawning is dictated by temperature, not season. The similitude of the observed species to those observed in warm temperate South Africa highlights the historical connection of the warm-temperate study area with warm-temperate South Africa, prior to the formation of the Benguela Current as a vicariant barrier. The classification of the study assemblage into established estuarine utilization categories showed that the surf zone hosted more exclusively marine species than comparable surf zones in South Africa, attributed to the absence of estuaries in southern Angola. However, the observation of the marine estuarine dependent Mugil cephalus in this study area devoid of estuaries suggests that estuarine dependency may be regionally specific for some taxa. It appears that the warm, sheltered, nutrient rich waters of Tombua Bay provide typically estuarine associated taxa with a suitable alternative, non-estuarine nursery habitat. This study provides evidence that the importance of estuaries as critical nursery habitats has been overemphasized for some warm-temperate coastal fishes. However, the absence of other marine estuarine dependent species from the study area suggests that some warm-temperate taxa do intrinsically rely on estuarine function for survival.

- Description: Ecosystem engineering refers to the way that organisms control the structure and function of ecosystems. It has been suggested that palmiet (Prionium serratum, Thurniaceae) works as an ecosystem engineer, shaping peat wetlands in South Africa. However, there is currently a paucity of evidence supporting this claim. Palmiet has a dense root, rhizome and stem system that forms dense stands, growing from channel banks into fast flowing river channels. This slows river flows, traps sediment, which builds up riverbeds and ultimately blocks river channels, turning the river into a wetland. The aim of this study was to determine if palmiet is an ecosystem engineer and to document its pattern of colonisation and the nature of its control of a fluvial system. This was achieved by undertaking vegetation surveys in the Kromrivier Wetland in the Eastern Cape. The data was analyzed using vegetation classification and ordination, where vegetation communities were linked to environmental factors. It was found that palmiet occupied three distinctive habitats; 1) on near-horizontal valley- bottom habitats filled with sediments that are a mixture of autochthonous organic sediment and allochthonous clastic fines, 2) the bed of gullies that have recently filled with coarse grained clastic sediment, and 3) open water bodies. Three conceptual models were developed, one that accounts for the process of gully bed colonisation, sediment trapping and gully filling, another involving rapid colonisation of sedimentary fill from tributary sediment sources that block a gully, and the third involving colonisation of open-water areas that form in former gullies upstream of the blockage. The study suggests that the wetland has been characterised by repeated cutting and filling cycles, despite which, palmiet has repeatedly reinstated diffuse flow conditions across the valley floor. Palmiet was indicated to exert a key control on fluvial form and dynamics of the wetlands in the Kromrivier valley.

Drawing predominantly on archival sources the primary concern of the thesis is to expose and interrogate certain aspects of this historical moment of popular politics which can be seen as emancipatory. In particular the notions of egalitarianism and universal human dignity will be analysed in relation to the popular political subjectivities, formations and praxes of the Mpondo revolts. In so doing this thesis attempts to make a meaningful contribution to present day debates concerning alternative theories of human emancipation by showing what emancipatory politics looked like historically and in practise within the context of the Mpondo revolts.

- Description: My short stories are about the circumstances in which black gold miners in Welkom in the 1980s and 1990s found themselves. These mineworkers - I was one of them - made up a large, uneducated segment of personnel because our work required strength and good health only. We came from all over the African continent. The places we had to live in were like jails or military barracks, sometimes with twenty or more of us sharing a single room. Because of these conditions, we shared our pains, and the pains of wives, children and relatives of those who were killed or disabled by their work, the repatriation of those who lost their capacity to continue working because of accidents and work, and work-related illnesses. We did not share the same language, and so we had to learn Fanakalo, the language of South African mine workers. My stories show how pain and happiness rub shoulders with each other in the miners' life, because besides the dangerous work there was also cultural entertainment, religious practices, robbery by tsotsis, and many prostitutes. The book Buzani Kubawo by Witness K. Tamsanqa has been an important influence on my writing. Other influences have been L.L. Sebe's Ucamngco and P.T. Mtuze's Alitshoni Lingaphumi. , La mabali angeemeko zabembi-migodi baseWelkom phaya kwiminyaka ephakathi koo-1980 noo-1990. Aba basebenzi, endandingomnye wabo, babeliqela elivisayo elingafundanga — bezingca ngamandla. Sasiphuma mbombo zonke zeli lase-Afrika. Indawo esasihlala kuyo ibifana nqwa nezisele zentolongo okanye izindlu zasemkhosini. Amashumi amabini amadoda elala ndlwini - nye. Ngenxa yaloo meko sachubelana amabali ngeemeko zobomi bethu, ngabafazi nabantwana, nezizalwane, nangeengozi esasingena kuzo nokugoduswa kwabo bagulayo. Kwathi kuba sasithetha iilwimi ngeelwimi safundiswa isiFanakalo. Amabali am abonisa iintlungu ezayame kulonwabo kuloo meko yasemigodini kuba yayikho nemidlalo nemigcobo ezonwabisayo ngokweentlanga ngeentlanga. Sasikwajongene nootsotsi kunye neentwazana ezithengisa ngemizimba. Ababhali abathe banefuthe ekubhaleni kwam baquka aba: uW.K. Thamsanqa ngencwadi yakhe ethi "Buzani kubawo," uP.T. Mtuze ngeyakhe ethi "Alitshoni Lingaphumi," kunye no L.L. Sebe ngencwadi yakhe ethi "Ucamngco."
