- Description: In the age of digital media, creators are using the versatile nature of information and communication technologies and the ubiquity of the web to publish and distribute texts, circumventing traditional gatekeepers such as publishing institutions. In Africa, where web access and digitisation are relatively new, storytellers are eagerly exploring new mediums and the possibilities that they provide for African narratives and African representation. This thesis looks at the digital platforms of the African Storybook Reader, the FunDza Literacy Project, and Long Story SHORT, as well as Dudu Busani-Dube’s novel Hlomu the Wife, which first gained popularity on a blog platform. It examines three different web series, An African City, The Foxy Five, and Tuko Macho, as well as a transmedia documentary, Love Radio. The texts are grouped into literatures disseminated from digital platforms, localised narratives that explore the urban African woman, and narratives that make use of participatory culture. These are texts that make use of digital tools and platforms to create and disseminate African stories, making diverse and indigenous narratives more easily accessible to both local and global audiences. This thesis argues that digitisation and the global nature of the internet have created opportunities for Africans to become producers and exporters of indigenous information and representation, rather than passive consumers of imported knowledge, or subjects of external characterisation.

- Description: The aim of this study was to develop an understanding of the experiences of caregivers of children with physical disabilities and to explore ways of improving this experience. Although there is a considerable amount of international research on the experiences of caring for children with disabilities, the focus of the methods of enquiry has mainly been on knowledge production and there is limited research conducted using an approach like participatory action research. Secondly, in South Africa, there is still inadequate information regarding the experiences of caregivers who are from low socio-economic backgrounds. It is for these reasons that the current study, which employed PhotoVoice, a participatory research data collection tool, to explore the lived experiences of caregivers of children with physical disabilities from low socio-economic backgrounds was embarked upon. The research methodology comprised two main parts: firstly, a study of relevant literature on the subject matter, in order to gain in-depth understanding of the field; and secondly, qualitative data collection, using PhotoVoice. A sample of six participants between the ages of 22-57 years was selected through purposive and convenience sampling. Cameras were distributed to participants and after processing of images narratives were shared around selected photographs and this was later followed by focused group discussions. This analysis process provided two master themes, which are supported by subordinate themes. The master themes are: 1) The challenges associated with the caregiving experience, 2) The positive side of the caregiving experience. Participants experienced a lack of resources, challenges of mobility, the hopelessness of the situation, loneliness of the experience and the financial burden of caring for a child with physical disabilities as challenges associated with the caregiving role. Whereas the joy brought about by support from family, the health service providers and the Association for People with Physical Disabilities personnel; precious moments shared with the child; and personal growth were associated with the positive side of the caregiving experience. These findings support and expand on the growing knowledge of caring for children with physical disabilities. This research culminated in a sharing of the narratives with stakeholders by caregivers themselves as a way of seeking to influence policy, enhance their well-being and engage in a discussion of exploring ways of improving their experience.

- Description: Sexual harassment continues to be a pernicious problem in institutions of higher education globally and findings indicate that women are the main victims. Extant research has focused largely on experiences of sexual harassment on the part of students. Under-researched are the experiences of academics concerning what Benson (1984) terms “contrapower” harassment -- that is, harassment experienced by academics from subordinates such as students. South Africa’s Ministerial Committee on Transformation and Social Cohesion and the Elimination of Discrimination in Public Higher Education Institutions reported that there exists a culture of silencing around the prevalence of sexual harassment in higher education institutions in South Africa (Soudien Report 2008:37). The concept of power has been pointed out as central to understanding sexual harassment (Cleveland and Kerst 1993:49). Utilising three main constructs in Michel Foucault’s conception of power, namely the idea that power is ubiquitous and omnipresent in social relations; that power disciplines – creating docile bodies and the internalisation of self-regulation, and finally the idea that power is productive – power produces knowledge, truth and forms of resistance, I interpret the experiences of contrapower harassment in its sexual and non-sexual forms on the part of female academics at various universities in South Africa. Given that there is a paucity of qualitative research documenting experiences of contrapower harassment on the part of female academics, this thesis draws on 13 in-depth qualitative interviews with female academics at various South African universities who have experienced contrapower harassment from their students and subordinates at any point in their teaching careers. Their narrated experiences provide insight into the phenomenon of contrapower harassment. These insights provide a window into how female academics continue to experience themselves as being out of place in post-apartheid institutions that are expected to be accommodating of all.

- Description: Zakes Mda is a prominent post-apartheid black South African novelist whose style has been described as experimental. He also wrote plays intended to ‘rally people to action’ during the apartheid years. The changes in the political and social situation in South Africa since 1994 have had significant implications for those writers and artists who produced protest literature and art. The changes in Mda’s own practice and approach to art are themselves quite telling. His experimental novels place him among those African artists pioneering a new chapter for black South African art and the self-reflexive nature of his novels suggest that he is aware of the fact and is consciously forming and reforming his ideas about what it means to be an artist in post-apartheid South Africa. This study will unpack the role of the artist and the function of art in the becoming new South Africa as represented in Zakes Mda’s novels, thereby hypothesizing Mda’s aesthetic philosophy, as may be deduced from his practice, for what an African artist and art should be. This will be done first by locating Mda in the debates around art and literature within the sociopolitical context of a South Africa in transition. Despite the fact that when it comes to public action in the post-apartheid situation, Mda distinguishes between his own role in society as an artist who is a social activist and the role intended for his work, his own novels reveal a desire for the artefact (or artwork) to have a developmental, educational or conscientizing function. This is evident in representations of the effects of art in what this study proposes to be his extended South African black Kunstlerroman, which spans three novels. It is also demonstrated in his ekphrastic novel, The Madonna of Excelsior, in which visual art is interpreted in the process of description, thereby educating the reader. Not only that, but the reader is made into an ‘almost viewer’ and taught how to ‘see’ art. What emerges in the process of this study is Mda’s aesthetic philosophy or what may be termed his ‘aesthetics of liberation’ concerning the role of the artist in post-apartheid South Africa, a suitable African audience and how art works theoretically, as expressed through his fiction.

- Description: This thesis aims to respond to the rise in the production of science fiction in Africa over the last decade, and to show how what I describe as the juju orientation of many of these works does not disqualify them from the genre of science fiction. Rather, I advocate for the recognition of juju ontologies as genuine sources of knowledge about the world, which have been overlooked by the globally dominant scientism that has informed science fiction theorisation to date. In my introduction I outline the theoretical frameworks of juju, science fiction and epistemology with which the thesis is in communication. In my second chapter I re-read Amos Tutuola’s novel The Palm-Wine Drinkard, showing the inherently science fictional structure of the juju-based storytelling that characterises colonial and pre-colonial African literature, as well as the essentiality of science fictional modes to Tutuola’s own prose. My third chapter considers Ian MacDonald’s theorisation of a jujutech aesthetic in African science fiction, wherein the speculations of the genres are rooted in both technoscientific and juju ontologies simultaneously. I account for the role this literary aesthetic plays in Ekari Mbvundula’s “Montague’s Last” to blur the divisions of worldly knowledge enforced by global epistemological inequalities, before showing how Dilman Dila’s A Killing in the Sun presents a critically frontier African epistemology in literary practice, and the value thereof. My fourth chapter considers the role of popular culture and consumption, and how the global literary industry resists juju-based texts. I conclude that juju-based nova and the jujutech aesthetic are not only essentially science fictional literary modes, but important players in science fiction’s role in being epistemologically productive in the future.

- Description: Rhodes University was awash with political tension and activity in the 2015 and 2016 academic years. The University had been the scene of radical protests and demands for change by students. The #RhodesMustFall, #FeesMustFall and the #RUReferenceList protests at Rhodes University started debates, conversations and public lectures amongst students and staff on and off social media on aspects of decoloniality, transformation, free education, issues of safety on campus and gender-based violence (Grocott’s Mail, 2015b). However, very little of this was reflected in the election campaigns of political parties and seemingly, in student engagement with political processes, at least as reflected in this election. The three biggest political parties in South Africa, and the only ones that contested Ward 12 (Rhodes) ANC, EFF, and the DA, were active on social media aiming to directly engage with constituents and draw citizens to the polls. All the parties had former and current Rhodes University students as candidates for councillor. There was a substantial engagement by students on social media, on the Rhodes SRC Facebook page, and on Twitter. However, only 39% of registered students, turned out to cast their vote on election day (IEC, 2016b). This study examines the interpretations and meaning-making amongst young people at Rhodes University, of the political party messages during the 3 August 2016 local government elections on social media. In addition, the study sought to understand whether youth at Rhodes (Rhodes University) actively sought out political party messages on social media (by following the ANC, DA, EFF Facebook and Twitter accounts), or were the messages incidental on their timelines (for example, following news organisations). Finally, the study sought to understand whether the media messages resonated with them and spoke to the issues faced by young people on the campus. The research used qualitative thematic content analysis and focus group discussions to examine the relationship between the content provided by the political party messages and the audience’s process of making sense and derived meaning from the content. Six focus group discussions were convened. This study found that young people are social media enthusiasts, they actively sought election related content on social media by following the Twitter and Facebook accounts of the parties, and from news organisations. Furthermore, the study discovered that, although, young people engaged with the political party messages on social media, they did not feel like the messages were targeted at them, and as such they felt the messages did not speak to them and the issues they face.

- Description: Background: Non-communicable diseases (NCDs) are responsible for 38 million deaths annually, which translates to 68% of global deaths every year. Incidence and prevalence of NCDs are increasing rapidly and the poor bear a disproportionate burden. The increase in NCDs has been primarily due to a proliferation of modifiable risk factors, such as unhealthy diet, physical inactivity, tobacco use, and excessive alcohol consumption. Substance abuse, mainly of alcohol, is a common cause of health problems in almost all countries across the globe. Alcohol abuse is a major contributor to the global burden of diseases and accounts for 3.3 million deaths, approximately 5.9% of all global deaths, annually. Alcohol misuse is the fifth leading risk factor for premature death and disability and is the top risk factor among people between 15 and 49 years of age. The rise of harmful use of alcohol in South Africa contributes to the disease burden faced by the country, with alcohol-related disorders making up 44.6% of all alcohol-attributable disabilities. Strategies to reduce harmful use of alcohol include national policies and educational interventions including health promotion. Health promotion is a common practice in the prevention of NCDs, but workplace health promotion has not yet been well established in many workplaces. Identification of past workplace initiatives and exploring their facilitating and limiting factors is thus important to consider when planning future initiatives. Raising awareness on harmful use of alcohol through workplace health promotion projects can help to prevent and reduce alcohol-related problems. For these health promotion activities to succeed, they need to be developed with consideration of factors such as the environment, culture, and socio-economic standing of the intended target population. Method: This study, conducted at Rhodes University, followed a mixed methods research approach and consisted of two phases. The first phase of the current study was a needs assessment and involved working with the key stakeholders. Using the Community Based Participatory Research approach and the Centres for Disease Control and prevention workplace health model to guide the research, five semi-structured interviews were conducted with key stakeholders to identify factors affecting workplace health promotion, and their opinions on how to improve these initiatives were sought. The participants were asked to identify areas on which the intended intervention should focus, as well as to identify their preferred means of communicating health messages. During this phase, a group of peer educators who volunteered their involvement in the health promotion project focusing on harmful use of alcohol was also identified. The second phase of this project aimed to address concerns raised in the first phase through a health promotion initiative for support staff that focuses on the prevention of NCDs diseases through reducing alcohol related harm. During the educational health promotion phase of the study, three health information leaflets based on harmful use of alcohol were designed. These leaflets went through a series of evaluations by the researchers’ peers, support staff during a pilot study, peer educators and other health professionals to assess content validity, context specificity, and cultural appropriateness for the target group. The health information leaflets were then used as written materials in the educational intervention of the project and were also used to design a poster. Through participatory involvement, a facilitator’s manual on harmful use of alcohol was developed, which was used during the workshops in the implementation phase of the research. The facilitator’s manual was modified based on provided feedback on improving the content of the facilitator’s manual. The readability of the manual was also performed to make it suitable for the end users. The peer educators were also trained through workshops to enable them to promote and raise awareness on harmful use of alcohol to others in the workplace. Workshops were participatory in nature and were also equipped with the completed health information leaflets to distribute to their peers and to use as reference sources of information when needed. Results: Participants in the semi-structured interviews reported that some health promotion initiatives have previously been attempted and advertised to support staff, but there was poor participant participation. Peer educators reported that these initiatives were not communicated to them and venues and work commitments sometimes were barriers to participation in these projects. The peer educators suggested incentivising initiatives for better participation. Another key suggestion was to inform and to include their managers and supervisors in these initiatives so they are permitted to take time off work. Health education material like posters or leaflets were also proposed as modes of delivering health information. During the design of the material to be used for this project’s intended intervention, the health information leaflets were deemed readable, suitable, actionable, context-specific, and culturally appropriate. Workshops conducted during Phase 2 of the study proved to be valuable in training peer educators. Peer educators also deemed the workshops useful, and reported their readiness to be agents of change in the workplace. Conclusions: Based on the input of key stakeholders and peer educators, there is currently no health promotion policy at Rhodes University, especially with respect to NCDs health promotion policies and protocols for NCDs. Health promotion initiatives, especially for support staff, that address NCDs have previously been attempted at the university but were not successful. Factors affecting workplace health promotion were identified. Knowledge of these factors was useful when implementing the health promotion project on harmful use of alcohol. The health leaflets were deemed suitable for use by the target population. Peer educators who went through the workshops and were provided with the facilitators’ manuals concluded that the sessions were useful in their continued participation in the health promotion project. Continued involvement of the Wellness Office and peer educators can assist in ensuring the sustainability of this workplace health initiative.

- Description: Background: Non-communicable diseases (NCDs) are responsible for 38 million deaths annually, which translates to 68% of global deaths every year. Incidence and prevalence of NCDs are increasing rapidly and the poor bear a disproportionate burden. The increase in NCDs has been primarily due to a proliferation of modifiable risk factors, such as unhealthy diet, physical inactivity, tobacco use, and excessive alcohol consumption. Substance abuse, mainly of alcohol, is a common cause of health problems in almost all countries across the globe. Alcohol abuse is a major contributor to the global burden of diseases and accounts for 3.3 million deaths, approximately 5.9% of all global deaths, annually. Alcohol misuse is the fifth leading risk factor for premature death and disability and is the top risk factor among people between 15 and 49 years of age. The rise of harmful use of alcohol in South Africa contributes to the disease burden faced by the country, with alcohol-related disorders making up 44.6% of all alcohol-attributable disabilities. Strategies to reduce harmful use of alcohol include national policies and educational interventions including health promotion. Health promotion is a common practice in the prevention of NCDs, but workplace health promotion has not yet been well established in many workplaces. Identification of past workplace initiatives and exploring their facilitating and limiting factors is thus important to consider when planning future initiatives. Raising awareness on harmful use of alcohol through workplace health promotion projects can help to prevent and reduce alcohol-related problems. For these health promotion activities to succeed, they need to be developed with consideration of factors such as the environment, culture, and socio-economic standing of the intended target population. Method: This study, conducted at Rhodes University, followed a mixed methods research approach and consisted of two phases. The first phase of the current study was a needs assessment and involved working with the key stakeholders. Using the Community Based Participatory Research approach and the Centres for Disease Control and prevention workplace health model to guide the research, five semi-structured interviews were conducted with key stakeholders to identify factors affecting workplace health promotion, and their opinions on how to improve these initiatives were sought. The participants were asked to identify areas on which the intended intervention should focus, as well as to identify their preferred means of communicating health messages. During this phase, a group of peer educators who volunteered their involvement in the health promotion project focusing on harmful use of alcohol was also identified. The second phase of this project aimed to address concerns raised in the first phase through a health promotion initiative for support staff that focuses on the prevention of NCDs diseases through reducing alcohol related harm. During the educational health promotion phase of the study, three health information leaflets based on harmful use of alcohol were designed. These leaflets went through a series of evaluations by the researchers’ peers, support staff during a pilot study, peer educators and other health professionals to assess content validity, context specificity, and cultural appropriateness for the target group. The health information leaflets were then used as written materials in the educational intervention of the project and were also used to design a poster. Through participatory involvement, a facilitator’s manual on harmful use of alcohol was developed, which was used during the workshops in the implementation phase of the research. The facilitator’s manual was modified based on provided feedback on improving the content of the facilitator’s manual. The readability of the manual was also performed to make it suitable for the end users. The peer educators were also trained through workshops to enable them to promote and raise awareness on harmful use of alcohol to others in the workplace. Workshops were participatory in nature and were also equipped with the completed health information leaflets to distribute to their peers and to use as reference sources of information when needed. Results: Participants in the semi-structured interviews reported that some health promotion initiatives have previously been attempted and advertised to support staff, but there was poor participant participation. Peer educators reported that these initiatives were not communicated to them and venues and work commitments sometimes were barriers to participation in these projects. The peer educators suggested incentivising initiatives for better participation. Another key suggestion was to inform and to include their managers and supervisors in these initiatives so they are permitted to take time off work. Health education material like posters or leaflets were also proposed as modes of delivering health information. During the design of the material to be used for this project’s intended intervention, the health information leaflets were deemed readable, suitable, actionable, context-specific, and culturally appropriate. Workshops conducted during Phase 2 of the study proved to be valuable in training peer educators.

- Description: While research has explored the risk factors that contribute to alcohol use during pregnancy among South African women, such studies have mostly been quantitative in nature. There is a growing body of research that contextualises and articulates the attitudes, beliefs, and underlying motivations that influence drinking during pregnancy. However, few qualitative studies explore the cultural, economic, familial, and social contexts within which drinking during pregnancy takes place. Studies which have explored these contexts have been conducted in other geographical regions such as Australia, Canada, New Zealand, and the United States but their findings are not generalisable to South Africa. Drawing on a feminist poststructuralist as well as a narrative-discursive approach including Foucault’s (1978) theory of power, this study sought to explore women’s narratives of the personal and interpersonal circumstances under which drinking during pregnancy takes place in terms of the discourses used to construct these narratives and the subject positions made available within these discourses. This allowed for the practice of alcohol use during pregnancy to be understood within the social and cultural narratives, practices, and discourses around pregnancy as well as gendered and social relations. Using the narrative interview method set out by Wengraf (2001), thirteen, unemployed ‘Black’ women from an area in the Eastern Cape were recruited and interviewed. Seven discourses emerged from the narratives namely, a discourse of ‘stress and coping’ ‘hegemonic masculinities’, ‘peer pressure’, ‘disablement and developmental delay’, ‘good mothering/appropriate pregnancies’, ‘culture’, and ‘religion’. These discourses informed the five narrative categories which emerged: narratives about the pregnancy, narratives about the drinking, narratives that justify/explain drinking, narratives that condemn the drinking, and narratives about the women knowing the effects of drinking during pregnancy. Within these narratives, the women mainly positioned themselves as dependent on alcohol during their pregnancies in order to cope with stress caused by various circumstances which were mainly centred on a lack of support from their partners, paternity denial, infidelity and unreliableness. As such, the women in this study mainly justified their drinking during pregnancy and in constructing this narrative, the ‘stress and coping’ discourse as well as the ‘male/masculine provider’ discourse were mainly drawn upon. In reflecting on this analysis, this study argues that alcohol use during pregnancy should be understood within the broader environmental and social context that makes a pregnancy challenging and/or difficult and thus necessitates drinking during pregnancy. Recommendations for future research include expanding the diversity of participants as well as interviewing healthcare providers and women who are currently pregnant, drinking, and part of an intervention aimed at addressing alcohol use during pregnancy so as to obtain a holistic understanding of engaging in this practice. The study makes key recommendations for interventions in practice to help work towards ensuring that the practice of alcohol use during pregnancy is not individualised, decontextualized, and stigmatised.

- Description: This thesis comprises two sections: the first section considers who is a refugee and who is not a refugee; and the second section illustrates the necessity of amending the present international laws and conventions to include other people who should also be recognised as refugees. The critical issue regarding the definition of a refugee, is whether or not there is adequate evidence concerning the current understanding of the notion of who a refugee is. Therefore, in order to reach these goals, this thesis is divided into five chapters. The first chapter explores the definitions pertaining to what it means to be a refugee. The second chapter takes into account the different types of victims that are excluded from the notion of refugee. The third chapter considers the consequences of having a restricted understanding who qualifies to be a refugee. The fourth chapter provides alternative solutions that would assist in providing a more comprehensive definition. Furthermore, chapter five discusses the necessity to further expand the refugee concept to include other forms of victims that are not already included. Overall, this thesis seeks to support expansion of the term ‘refugee‘ since the reasons for forced migration have changed, and individuals are not only fleeing from individual persecution, for instance, but from other situations that can be considered to fall under forced migration. Consequently, extending the definition of the term ‘refugee‘ should occur, because refusing to consider revising the term amounts to a refusal to show acceptance and empathy to today‘s other migrants who are also experiencing survival challenges in their home countries.

- Description: This study explores the construction of the identity of professional pilots through a case study of a flying school in South Africa. Here, a 15-20-month period of intensive study and training of students, fresh from school or college, leads in most cases to the attainment of a Commercial or Airline Transport Pilot’s Licence. The construction of identity is a continuous process and a lifelong project and hence this study can only reflect upon the factors influencing the early stages of a pilot’s career, until the point where the licenced Pilot leaves the Air School and enters full time employment with a commercial undertaking, but it is argued that this is a crucial step in the formation of professional identity, habitus in Bourdieu’s terms. The culture of the air School reflects the military background of the founders of the school and the staff employed in senior positions. The school, which is residential, observes a strict regime of Ground School and Practical Flying Training and a high standard of performance and personal conduct is demanded, both during training and in off duty hours and excessive consumption of alcohol and smoking are discouraged, and drug use absolutely taboo. Progress with training at the school is closely monitored and a disciplined environment maintained by surveillance cameras, house monitors and security guards; in Foucauldian terms, a modern version of the Panopticon, but somewhat less than Goffman’s Total Institution. It was found that the construction of a flying identity for most of the students entering the air school commenced in childhood or early adulthood, through the influence of friends and relatives and they enter the school with the firm intention of becoming Professional pilots. Full participation of the author in the Ground School revealed how professionalization is implemented through the discipline and rigor of the training methods employed. Through mastery of a complex body of theoretical knowledge in the Ground School and the practical skill of learning to fly in a one-on-one relationship with an instructor, the students gain confidence and efficacy which contributes to their self-respect and maturity. The international reputation of the school, confers prestige upon its graduates and they benefit from membership of a profession which commands respect and a high level of income. In large measure, the thesis shows, the success of the School is a function of the founders’ ‘invention of tradition’ focusing on the wartime training school that existed on the site and the many echoes of those times in the (re)construction of its buildings and facilities, continuing in the approach of the multinational that now owns the School.

- Description: This dissertation explores what a sample of South African lawyers understand about the roles they play in digital public spaces, and whether they perceive their contributions as impacting on journalism in general and legal knowledge among the public more broadly. The communications revolution triggered by web 2.0 interactivity has created a new media ecosystem in which mainstream media journalists co-exist with a variety of non-journalist content producers - including professionals like lawyers, who contribute to media content. This study specifically explores current debates about how the media ecosystem is changing in the digital age, including journalistic practices and routines and the role of journalism within a democracy and daily life. Thomas Hanitzsch and Tim Vos’s recent taxonomy of journalistic functions and roles in society is adapted by combining the domains of politics and daily life, to better describe the roles of non-journalists like the eleven digitally active members of the South African legal community in this study. Using qualitative interviews and content analysis research methods, the study suggests lawyers’ practices and routines challenge current theorisation about the new media ecosystem and digital public sphere in particular ways, suggesting that the affective nature of social media interactions between the lawyers and members of the public is more usefully understood via drawing on Chantal Mouffe’s concept of agonistic public spaces and Axel Bruns and Tim Highfield’s theorisation of ‘public sphericules’ than Jurgen Habermas’s conceptualisation of a rational public sphere. The study found that all of the digitally active lawyers played one or more active roles in contributing news, opinion and debate about legal and social justice matters on different digital public spaces, even though most were reluctant to describe what they do as journalism. The study concludes that this select group of lawyers do complement and enhance the work of journalists covering the legal field in the new media ecosystem in South Africa. It suggests that much more can be done by both journalists and the legal community to deepen co-operation to further enhance public knowledge about the workings of the South African legal system, in relation to legal rights and the rule of law.

- Description: My novella comprises inter-linked fragments that combine fiction, autobiography and creative non-fiction. Ranging fluidly from pre-colonial times to the present, and largely set in South Africa but cutting across the native/diaspora divide, the project draws on historical and archival documents, found and fictive letters, oral testimonies and inadmissible facts, mythologies, ghost voices and fictional speculation. It uses the slim slippery voice of autobiography to cast a big shadow of doubt on the certitudes of authorial truth, harnessing multiple voices to disorient settled notions about self/other, black/white and man/machine. My intention is to explore possibilities of being that exceed the human. I draw inspiration from Zoë Wicomb's novella, You Can’t Get Lost In Cape Town, Mariama Ba’s So Long a Letter and Mikhail Shishkin’s letter-narratives in Maidenhair. The narrative voice that threads stand-alone fragments seeks to express the demotics of subjects in search of a language for their unlanguaged ‘grammar of suffering’.

All mid-vowels preceding a high vowel take on the feature advanced tongue root (ATR) (e.g. thɛnga ‘buy’ → thengisa ‘sell’; bɔna 'see' → bonisa 'cause to see') (Harris 1987). The process of mid-vowel assimilation for the feature [+ATR] is consistent in all instances in which the mid-vowel occurs preceding a high vowel trigger, unless harmony is blocked by the low opaque vowel [a]. This is the analysis presented in Jokweni & Thipa (1996) the only previous literature to address the vowel harmony process of isiXhosa in detail. As an alternative approach to the rule-based phonology applied in the analysis presented by Jokweni & Thipa (1996), I propose the introduction of Optimality theory (OT) (Prince & Smolensky 1993, Bakovic 2000, and Pulleyblank 2002). I will present a map of the harmony system of isiXhosa using OT, while also presenting acoustic data to supplement the selected examples provided in Jokweni & Thipa (1996). This acoustic investigation will determine whether the harmonic feature is ATR, and how this feature patterns among vowels in different phonological contexts. In this paper vowel harmony is achieved through the implication of numerous rules, and with very specific directional and prosodic limitations on the spread of [+ATR]. Using generalisations based on my own collected data as well as those reported in previous literature, I have developed a constraint ranking to account for the harmony process in isiXhosa. By adapting the No-disagreement approach to harmony (Pulleyblank 2002), the final constraint ranking has the capacity to derive the optimal phonetic candidate for every harmony case. A selection of spread constraints is used to account for the raising as well as blocking processes, by driving either regressive or progressive spreading. Within the original No-disagreement approach a spread constraint would recognised only one feature in its prohibition of disagreeing segments. However, in the adapted approach the spread constraint driving [+ATR] assimilation is combined with a feature of correspondence (Krämer 2001) which considers the height as well as the ATR value of the sequential segments. The constraint is therefore adapted to consider more than one feature and is not activated unless the sequential segments agree for this particular feature. The regressive spread constraint is therefore only activated when the consecutive segments have an agreeing height value. The introduction of this adaptation was necessary to provide a more nuanced OT approach with the capacity to effectively characterise the idiosyncrasies observed in this harmony pattern. The harmony constraints are therefore no longer contradict one another by simultaneously driving harmony in opposite directions. Furthermore, the direct acoustic analysis is completed by means of the PRAAT software, to answer the salient question of the definitive harmonic feature. To provide a multiplicity of empirical evidence I have recorded utterances containing a number of vowel combinations. Each combination positions the alternating mid-vowels in a particular phonological context from which instances of ATR alternations have been extracted and phonetically analysed. Using the generalisations reported in Jokweni & Thipa (1996) as a starting point, the acoustic signal of each mid-vowel within a set phonological context is annotated for a predicted ATR value. Hence, if a mid-vowel occurs preceding a high vowel it is annotated as [+ATR] etc. The data sets representing each of the mid-variants found in a specific phonological context are then plotted into vowel charts and compared by means of statistical analysis (Baayen 2008, Bluman 2000). The results are then used to determine whether any significant phonetic alternation is occurring, and what the acoustic distinction between [+ATR] & [-ATR] variants is essentially comprised of. The final acoustic results indicate a significant difference between the mid-vowel ATR variants extracted from specific phonological contexts. Hence, due to co-articulatory effects or some other phonological influence the realisation of [+/-ATR] variants exist along a spectrum, and are therefore not phonetically consistent, but indicate a different acoustic make-up across the various groups.

- Description: Four different techniques to make taxonomic decisions concerning different species in Scarabaeinae are being investigated. Firstly, I made measurements of the body dimensions which are plotted on a two dimensional graph. This method is successfully used to erect one new species, Copris crassus Deschodt and Davis, 2015, and to establish the synonymy of Copris bihamatus Balthasar, 1965 with Copris fidius (Olivier, 1789). Thereafter the classical or traditional comparative method is used to propose seven new species Scarabaeolus soutpansbergensis (Deschodt and Davis 2015), Scarabaeolus megaparvulus (Davis and Deschodt 2015), Scarabaeolus niemandi (Deschodt and Davis 2015), Scarabaeolus carniphilus (Davis and Deschodt 2015), Scarabaeolus ermienae (Deschodt and Davis 2015), Scarabaeolus planipennis (Davis and Deschodt 2015) and Scarabaeolus afronitidus (Davis and Deschodt 2015) and formally synonymise Scarabaeolus vansoni (Ferreira, 1958) with Scarabaeolus lucidulus (Boheman, 1860) and Scarabaeolus xavieri (Ferreira, 1968) with Scarabaeolus andreaei (zur Strassen, 1963). Morphometric measurements of external structures of a group of flightless relict beetles in the tribe Canthonini are used to compile a nexus file which is analysed with computer software. The interpretation of these results is used here to support the erection of a new genus Drogo Deschodt, Davis & Scholtz 2016, Lastly I analysed the DNA sequences of specimens from different species belonging to a species complex in the genus Epirinus Reiche, 1841 occurring over a wide geographic range. These sequences are used together with external morphological characters to propose the synonymy of Epirinus hluhluwensis Medina & Scholtz 2005 and Epirinus ngomae Medina & Scholtz 2005 with Epirinus davisi Scholtz & Howden 1987.

- Description: Stable isotope (SI) ratios of carbon (δ13C) and nitrogen (δ15N) are now widely used as biomarkers in ecological studies to provide information about food web structuring. However, understanding trophic relationships using SI analysis requires not only knowledge of SI values of predator and prey, but also accurate discrimination factors (DFs), which can differ among species and by physiological state. This thesis examined three questions using captive birds from the South African Foundation for the Conservation of Coastal Birds (SANCCOB). First, the effects of ontogeny on δ13C and δ15N ratios of African penguins (Spheniscus demersus) were assessed. Blood samples were collected from penguins in four age classes (P3 chicks, blues, juveniles and adults) concurrently with their diet (sardine (Sardinops sagax) and formula). Second, to assess the influence of breeding physiology on SI ratios, the blood of ten breeding pairs of penguins was sampled over a five-month period from June to October 2016. Following laying, each pair was categorised into one of three (four for whole blood) egg production phases (initial yolk deposition, rapid yolk deposition and post-laying) and their influences on SI ratios were tested. Third, species differences in DFs were evaluated for African penguins, kelp and Hartlaub’s gulls (Larus dominicanus and L. hartlaubii), greater crested terns (Thalasseus bergii) and Cape cormorants (Phalacrocorax capensis). Flying birds were mostly fed sardine with a small but unknown amount of sardinella (Sardinella aurita), DFs were therefore estimated for a 50:50 sardine:sardinella diet, a 75:25 sardine:sardinella diet and a 100% sardine diet for each flying bird species. The DFs were assessed for the whole blood (WB), red blood cells (RBC), plasma (PL) and delipidated plasma of the penguins, and only WB for the flying birds as well as flesh, whole fish, delipidated flesh and delipidated whole fish for fish species, and for formula. Results indicated that age influenced both the δ13C and δ15N of WB, only the δ15N of RBC and the δ13C of delipidated PL. The assessment of breeding physiology yielded a significant interaction between the effects of egg production phase and sex on the δ13C of WB; females had significantly lower δ13C in the rapid yolk deposition phase than the other two phases and all males. The δ13C of PL was affected only by sex, with females having a significantly lower δ13C value than males. Neither physiological state nor sex influenced the other blood components. Differences were found among the three DFs in the non-penguin species, but not for all consumer – prey tissue combinations. There were also significant differences among species with a DF calculated from a diet with the most probable prey proportions eaten. Depending on the combination of consumer and prey tissue used to calculate the DF, a different conclusion regarding trophic information can be reached. A literature review updated with the present data showed that no general pattern or grouping of similar species with regards to DF values could be drawn, highlighting the importance of determining species- and tissue-specific DFs. Thus age, egg production, tissue and species all influenced the SI values of bird blood and therefore their DFs. Not all physiological conditions affect all blood components in the same way, making different components more or less sensitive to physiological influences. Though their influence is at a small enough scale that it is unlikely to hamper correct conclusion in ecological studies, it is crucial that these factors are considered when using SI analysis (SIA). When uncertainties exist for some coefficients in wild studies, SIA should therefore be combined to other dietary techniques to determine the food web structure as best as possible.

- Description: Wetlands are critical ecosystems that can provide services of great social, economic and environmental value to the society. Yet, in South Africa, hillslope seep wetlands are among the most threatened ecosystems due to human-induced activities and are disappearing rapidly. Further, despite the potential vulnerability of hillslope seep wetland to disturbances, and their criticality in relation to all year round provision of forage for livestock grazing, they are among the most poorly studied wetland systems. Using a social-ecological system framing, and drawing on a range of ecological and social sciences methods, this study shed light on ways in which an integrative approach can contribute to sustainable utilisation of hillslope seep wetlands in the Tsitsa River catchment in the Eastern Cape province of South Africa. The study specific objectives were to i) evaluate the performance of Floristic Quality Assessment Index (FQAI), WET-Health and Floristic Assessment Quotient for Wetlands Index (FQAWet) indices for assessing hillslope seep wetlands ecological health ii) develop a trait-based approach for assessing the potential resilience and vulnerability of hillslope seep wetland plant species to disturbances, iii) assess the role of hillslope seep wetlands in the local communities in relation to livestock, and explore understanding of local people about the value of hillslope seep wetlands, iv) demonstrate collaborative insights emerging from an integrative social-ecological system research process to inform sustainable management of hillslope seep wetlands. A total of 11 hillslope seep wetlands were visually classified based on the level of erosion. Plant species composition within the wetlands was determined along a 100 m line transects across the hillslope wetland sites. 5 quadrats of 0.2m2 were also placed along transect for vegetation collection and cover. The plant species collected were used to calculate (FQAI) and FQAWet scores to evaluate the condition of hillslope seep wetlands. The degree of human disturbances was assessed using the Anthropogenic Activity Index (AAI), an index for qualitatively assessing the degree of human disturbance based on visual inspection of a wetland site. Factors represented in the AAI, include: (i) surrounding land use intensity; (ii) soil disturbance; (iii) hydrological alteration; (iv) habitat alteration within wetland; (v) vegetation community quality. The vegetation samples were collected in summer 2016 and winter 2017. All assessed indices were regressed against AAI to evaluate their performances. All assessed indices FQAI, FQAWet and WET-Health showed that hillslope seep wetland were impacted by human activities. FQAIall and WET-Health showed the strongest response to AAI in winter, while FQAIdom and FAQWet showed a weak response to AAI in all seasons. Overall, the findings of this study suggest that FQAIall and WET-Health are potentially better tools for assessing the biological conditions of hillslope seep wetland in South Africa. A novel trait-based approach was developed using seven plant traits and 27 trait attributes. Based on the developed approach, plant species were grouped into three potentially vulnerable groups in relation to grazing pressure. It was then predicted that species belonging to the highly vulnerable group would be less dominant at the highly disturbed sites, as well as in the winter season when grazing pressure is at its highest. The result corresponds largely with the seasonal predictions; however this was not the case for sites. The approach developed in this study worked and it was useful for predicting the potential responses of plant species in hillslope seep wetlands to grazing pressure. The success of the approach seasonally could be attributed to the careful selection of the traits, reflecting the mechanistic relationship between the grazing mode of stress on vegetation and trait-mediated biotic response. However, this still need to be refined using accurate vegetation cover methods that might have had impact on the lack of correspondence within sites. The results of the present study revealed that communities largely perceive hillslope seep wetlands as important ecosystems for their livelihoods. They recognise that the importance stems from services provided by the wetlands, particularly for livestock grazing during the dry season. Although hillslope seep wetlands are viewed as important ecosystems for livelihoods, the communities also perceive these wetlands as highly eroded ecosystems. Community members indicate willingness to strengthen local natural resource governance systems, which could lead to better management of hillslope seep wetlands. A range of protective strategies for hillslope seep were suggested by community members, including fencing, active herding and rotational grazing. The study suggests that active involvement of local communities is critical to the successful management of natural resources. The study highlights the need to consider the role of local people as influential components within social-ecological systems in order to promote effective management and conservation interventions of hillslope seep wetlands. Overall, the study highlights the criticality of an integrative social-ecological system approach for holistic management of hillslope seep wetlands within the studied catchment.

- Description: The leerfish (Lichia amia), is a large, primarily coastal recreational fish species with a distribution extending from Portugal down the west coast of African to southern Mozambique. Owing to its large size (30 kg), strong fighting abilities and habit of taking surface artificial lures, this species has taken on an iconic stature among shore-based recreational anglers. Its reputation has made it an important angling tourism species that makes an important contribution to the economy of developing countries. For example, the species brought US$243 per harvested kilogramme into the local southern Angola economy. Despite its high value, little is known about its movement patterns in the northern Benguela coastal region, a region which includes southern Angola and northern Namibia. While much is known about the migratory patterns of the South African stock of L. amia, recent molecular studies have shown that the northern Benguela stock of L. amia has been isolated from the South African population for at least two million years, a consequence of the development of the cold Lüderitz upwelling cell in southern Namibia. Although the global population of L. amia is considered a single species, prominent biogeographic barriers within its distribution and subtle morphological differences between specimens captured within its tropical versus warm-temperate distribution suggest otherwise. A multi-method approach incorporating passive acoustic telemetry (PAT), recreational catch-per-unit-effort (CPUE) and conventional tagging (CT) in southern Angola, as well as recreational fisher-ecological knowledge (FEK) from Namibia, was used to investigate the large-scale movement patterns of L. amia within the northern Benguela coastal region. While each method had its own associated limitations, the combination provided a holistic picture of the population's seasonal migratory patterns. Furthermore, PAT successfully identified partial migration with 25% vs 75% of monitored fish exhibiting resident (movements < 100 km) or migratory (movements > 100 km) behaviour, respectively. Further behavioural diversity was observed with ‘resident’, ‘roaming’ and ‘embayment’ contingents identified based on varying levels of affinity to certain habitats. The presence of both resident and migratory individuals within the northernmost study during June and July, combined with available biological information, suggested that area-specific spawning may take place. While PAT, CPUE and CT largely aligned in determining area specific high-area use, results from network analyses and mixed effects models conducted on the PAT data supported the spawning hypothesis, with anomalous behaviour around specific receivers during the spawning season. All fish, regardless of behavioural contingent, displayed similar movement behaviour during the spawning season and this was driven by factors generally associated with reproduction, such as lunar illumination. Interestingly, these drivers were different from those that determined the area specific use of individuals outside of the spawning season. The environmental drivers of longshore migration into the northern study site were identified as a decline in water temperature and shorter day lengths. The results of this study highlight the importance of using a multi-method approach in determining migratory movement behaviour, area specific area use, and stock structure of key fisheries species. The identification of different behavioural contingents highlights the importance of acknowledging individual variation in movement and habitat-use patterns. This is particularly relevant as future climate change and spatiotemporal variation in fishing effort may artificially skew natural selection processes to favour certain behavioural groups. This study also highlighted the importance of scientists forming relationships with resource-users, such as recreational angling lodges in areas where limited research has been conducted. This is particularly relevant within the West African context where little is known about many of the fish species that are being increasingly targeted by tourism angling ventures.

- Description: The leerfish (Lichia amia), is a large, primarily coastal recreational fish species with a distribution extending from Portugal down the west coast of African to southern Mozambique. Owing to its large size (30 kg), strong fighting abilities and habit of taking surface artificial lures, this species has taken on an iconic stature among shore-based recreational anglers. Its reputation has made it an important angling tourism species that makes an important contribution to the economy of developing countries. For example, the species brought US$243 per harvested kilogramme into the local southern Angola economy. Despite its high value, little is known about its movement patterns in the northern Benguela coastal region, a region which includes southern Angola and northern Namibia. While much is known about the migratory patterns of the South African stock of L. amia, recent molecular studies have shown that the northern Benguela stock of L. amia has been isolated from the South African population for at least two million years, a consequence of the development of the cold Lüderitz upwelling cell in southern Namibia. Although the global population of L. amia is considered a single species, prominent biogeographic barriers within its distribution and subtle morphological differences between specimens captured within its tropical versus warm-temperate distribution suggest otherwise. A multi-method approach incorporating passive acoustic telemetry (PAT), recreational catch-per-unit-effort (CPUE) and conventional tagging (CT) in southern Angola, as well as recreational fisher-ecological knowledge (FEK) from Namibia, was used to investigate the large-scale movement patterns of L. amia within the northern Benguela coastal region. While each method had its own associated limitations, the combination provided a holistic picture of the population's seasonal migratory patterns. Furthermore, PAT successfully identified partial migration with 25% vs 75% of monitored fish exhibiting resident (movements < 100 km) or migratory (movements > 100 km) behaviour, respectively.

- Description: This study explores the different perceptions of mobile media in relation to development within Dwesa, a marginalised rural community in South Africa. The proliferation of mobile phones and increasing access to the internet in Africa, and South Africa in particular, is extensively documented and attempts have been made to explore its impact on development. Drawing on adapted aspects of the Diffusion of innovation theory (DoI), the study seeks to understand the relative advantage, compatibility with needs and values, and observable benefits of using mobile media for a rural community. I provide a critical discussion of the concept of development and its relationship with digital technologies and innovation. I reflect on the Diffusion of innovation theory, highlighting its critiques, adaptations and modifications in studies, particularly in the Global South. The present study employs a qualitative methodology and relies on focus groups, semi-structured interviews and observation as methods of data collection. Participants were divided into three focus groups based on Rogers classification of innovativeness (early adopters, majority adopters and late/non-adopters) and I conducted two follow-up interviews with participants of each focus group. I analysed the data thematically. Research participants identified several areas where mobile media contributed to development and positive change, such as lowering the cost of access to information and communication, staying in touch with distant relatives, increasing access to services and providing entertainment, especially among young people. The participants noted that despite these positive changes, that mobile media on its own cannot be expected to address challenges of infrastructure and public service delivery. Research findings also revealed that mobile media might interfere with socio-cultural values of respect, human dignity and privacy. I conclude that, while mobile media is generally considered as beneficial, its critical role in improving the socio-economic conditions of people in Dwesa still remains in doubt. The study provides an opportunity to further investigate the compatibility of mobile media with socio-cultural values along the lines of age and gender, and address issues of digital skills and digital marginalisation.

- Description: South Africa is characterised by cultural and biological diversity which constitute a unique context in which to conduct educational research, such as this doctoral study looking at human capital development in the marine biodiversity context. The drive for transformation in the country is also a major factor to consider when researching any sector of the economy, in this case, the biodiversity sector. The biodiversity sector includes organisations involved in biodiversity conservation, research and management. Previous research in the sector has found a clear need for well-thought out workplace skills plans within conservation and research organisations. The national Biodiversity Human Capital Development Strategy that was produced in 2010 by the South African National Biodiversity Institute outlines how all the organisations involved in the biodiversity sector of South Africa need to participate in strengthening the sector through a range of human capital development strategies. This includes extending the existing human capacity of managers and scientists who are already in the workplace, i.e. up-skilling. In particular, ‘scarce’ skills, as identified by the national Environmental Sector Skills Plan need further attention and development. The scarce skills relevant to this study are: protected area managers; ecosystem managers and post-graduate researchers, hence the focus on managers and scientists in this research. The marine sector falls within the biodiversity sector and it faces multiple conservation challenges which are complex and it is therefore essential to have skilled and capable managers and scientists in place. By investigating the up-skilling opportunities and practices available to these marine professionals, the goal is to understand if and how learning takes place in the marine sector of South Africa. The main research question of this study is: How do up-skilling opportunities and practices enable learning in, through and for the workplace, by marine professionals? In addition, three sub-questions provide finer details and introduce the central concepts of the research: I. What up-skilling opportunities and professional practices exist in or for, marine research and conservation organisations and how are they constituted and enacted via practice-based sayings, doings and relatings? II. How do the individuals learn and exercise their agency within the socio-material realities of the marine scientific and management context, through making use of up-skilling opportunities that are both formal (e.g. course based) and informal? III. How do generative mechanisms shape the constitution and enactment of up-skilling opportunities and practices, and the learning and agency of marine professionals (scientists and managers)? The theoretical work of this study consisted of, first, considering sensitising concepts which included: defining skill and knowledge; considering what an up-skilling opportunity might look like; workplace learning (both formal and informal learning); professional practices, lifelong learning or adult education, and agency in the workplace. Critical realism was then employed as the meta-theory that underlabours this research, while the substantive theories used for analysis purposes were socio-materialism and practice theory. Of course, critical realism is a socio-material theory itself, and Bhaskar’s four-planar social being or Social Cube was used to interpret and synthesise the findings in the data chapters. The methodological framework of this study explores the implications of critical realism for research design and analysis and includes a contextual profiling phase, semi-structured interviews, analysis of documents and peer-reviewed papers, as well as observations. There are nine case studies that form the focus of this research and in total 18 research participants were involved. Data analysis included abduction and retroduction as the primary modes of inference and the main analytical tool was the framework of practice architectures where I took the ‘sayings’, ‘doings’ and ‘relatings’ as themes. Further themes were developed from the other relevant theories used in this study; hence socio-materialism, learning, agency, and formal and informal opportunities, were also used as themes when coding the data. Issues around validity, ethics and reflexivity are key elements of the research design and were carefully considered throughout the research process. The principal data chapters are structured in such a way that each sub-question is considered and ultimately the findings are presented in the form of generative mechanisms which included: the politics of social transformation and knowledge as a driving force of up-skilling; the influence of individual disposition and passion or will; the importance of the socio-material realities and realistic expectations; and how relationality is critical for the marine sector. Agency was a cross-cutting theme in all the discussions around learning, practices and the role of the material, and was highly influential on the mechanisms that have been described in this study. The experiences, events and mechanisms that were uncovered in this research provide insight into the forms of learning as these relate to up-skilling that occur in the marine sector, as well as the complex relationships between formal and informal learning. The professional practices that occur in the everyday working lives of the marine professionals were shown to be an integral part of the learning process, while formal, certified opportunities are important for strengthening the field and building conservation competence in the country. By uncovering the deeper structures and mechanisms that have power and causal efficacy when it comes to up-skilling opportunities, learning and professional practices, this study has contributed to the field of environmental education as it shows how up-skilling processes operate in complex formations that involve formal and informal learning processes in workplaces. The study also offers a more nuanced view of the relational objects in this field, such as up-skilling and workplace learning, via the inclusion of a socio-material analysis. Through a theoretical and methodological framework that focused on the material using the tools of practice theory and Bhaskar’s depth ontology and four-planar social being (to synthesise and interpret the findings from a critical realist perspective), this research highlights the unique context of up-skilling opportunities and practices in the marine sector and reveals the crucial role of agency in workplace practices. This leads to a better understanding of the up-skilling opportunities and practices of marine professionals in South Africa, which ultimately contributes towards improved human capital development in the biodiversity and environmental sectors. Through offering more complex insights into the forms of learning and up-skilling, as well as a distinct methodological contribution, this research has broader relevance for workplace learning research.
