  • Description: This dissertation studies the musical lives of seven South African women who have built highprofile national and international careers as jazz musicians. Empirically it records self-reported experiences and actions that they have identified as relevant to their success within a notoriously patriarchal field. Drawing on feminist research methods and Interpretative Phenomenological Analysis the dissertation strives to develop an empathic yet critical epistemological framework attuned to the complexities of their lived experiences as women and as jazz musicians. Theoretically it investigates the power relations at play in the myriad ways they negotiate or have been impelled to negotiate gender and patriarchy as musicians. Chapter one draws attention to the ubiquity of patriarchy in South African and international jazz culture, and highlights the research participants’ numerous successes to date as performers, educators, composers, and bandleaders. Chapter two positions this study in relation to cognate work in South African jazz studies, international feminist jazz studies and feminist phenomenology. Chapters three to five successively consider the participants’ early enculturation as musical and gendered subjects, their agentic responses to structures of patriarchy and/or race as emerging and established professionals, and the ways these experiences have found expression in some of their musical utterances as performers and composers. Fusing art and activism, the participants challenge and transcend masculinist discourses of mastery that still dominate South African jazz as a field of production and aesthetic practice. , Thesis (PhD) -- Faculty of Humanities, Music and Musicology, 2023

  • Description: This study employs high-resolution hydraulic modelling techniques to inform the planning of rehabilitation interventions in unchanneled valley-bottom palmiet wetlands, using the upper Kromme River wetlands as a case study. It investigates the impact of geomorphic processes on the morphology of the valley, how changes in valley morphology affect the flow characteristics (velocity, stream power, depth) of the river, and how these changes affect the geomorphic dynamics of the wetlands. An aerial LiDAR survey was conducted for a 23km-long reach of the upper Kromme River where the wetlands are situated. A high-resolution (5 m) DTM was created from the LiDAR data to examine the valley morphology. Focusing on three major wetland basins, the relationship between valley morphology and geomorphic processes was examined using high-resolution imagery that accompanied the LiDAR survey and Google Satellite imagery. The hydraulic modelling software HEC-RAS was used to investigate the spatial variation in velocity, stream power, and water depth down the surveyed length of the river. The model outputs provide insight into the effect of valley morphology on flow characteristics. The river appears to have a graded longitudinal profile, such that there is a systematic reduction in slope down its length. Water flowing down the river works, through the processes of erosion and deposition, to control the longitudinal slope, channel planform, and geometry to create a valley with a gentle longitudinal slope (approximately 1%) and a broad, near-horizontal valley-bottom in the mountainous landscape of the Cape Fold Mountains. The overall form of the Kromme River valley and wetlands is primarily a consequence of repeated cycles of cutting and filling. Tributary alluvial fans control the initiation of gully erosion in the wetlands, but their effect is diminished in a downstream direction. Despite a 10-fold increase in discharge down the 23km length of river for a given flood magnitude, there is no significant increase in flow velocity, stream power, or depth in a downstream direction. Consequently, the kinetic energy of the water in the lower wetland basin is surprisingly low. These conditions favour the establishment of palmiet. Flows in eroded reaches are much higher than in non-eroded reaches where discharge is spread across a broad valley bottom. In terms of palmiet establishment and regeneration, this means that areas dominated by depositional processes are best suited to the establishment of palmiet. Based on this information, optimal sites to trial new wetland rehabilitation strategies that employ palmiet were selected. This work supports the importance of understanding the role of geomorphology in wetland structure and dynamics when approaching wetland rehabilitation and is likely to be more sympathetic to natural processes than current interventions. , Thesis (MSc) -- Faculty of Science, Geography, 2023

  • Description: The Jazz stream of the Curriculum and Assessment Policy Statement Further Education and Training music curriculum was introduced in South Africa in 2012 (DBE, 2011a). Despite the intentions of the government to promote diversity, social transformation, and inclusion, subject music is still weighted towards Western Art Music, perpetuating past biases of a Eurocentric model for music education. This study, which uses a mixed-method approach, seeks to create strategies to advance Jazz education in South Africa through an a/r/tographic analysis of the author’s Jazz pedagogical methods at Durban High School in KwaZulu Natal, South Africa. Key approaches include curriculum theory, currere, a/r/tography, among others. After reviewing Jazz pedagogy in the U.S.A. and South Africa as a starting point, using Pinar’s (1994) method of currere, the author demonstrates how past personal music educational processes have led to present Jazz pedagogical methods. Six original compositions were written that outline the influences that infused these methods and added to the creative output related to this research. Interviews were conducted with key stakeholders in the Jazz community to gain perspective about the current state of Jazz education, and with students to provide insight into their reactions to the Jazz stream of CAPS. This presents new information about the curriculum from a learners’ perspective. Ethical clearance for research with children was sought and received (Appendix A). Findings show that the ability of learners to recognise the value in, and identity relating to, their African culture through Jazz points to a pivotal departure from previous Eurocentric music education models. However, despite South Africa being positioned as one of the only countries offering Jazz as a subject choice to high school learners, the selection of Jazz in the subject of Music remains underutilised. This study concludes that for Jazz education to advance in South African high schools, there needs to be intentional engagement with Jazz professionals at the high school level. , Thesis (PhD) -- Faculty of Humanities, Music and Musicology, 2023

  • Description: Globally, SMEs are valued for their contribution to economic growth and development as well as for driving employment. To succeed, small firms require support especially in terms of obtaining funding and financial services that can enable them to meet day to day operational needs. Commercial banks play an important role for the financing of SMEs as small firms generally depend on bank loans to obtain external finance. However, despite the support and contribution, very little attention is given to the actual forms of finance used by small and medium-sized enterprises, the available finance made by lending institutions or investors and the relation between the use of the said debt finance and enterprise performance. Furthermore, several research studies carried out focusing on the effect of debt financing on performance of firms are inconsistent. Thus, this study sought to determine the effectiveness of bank debt finance on the growth of SMEs in Namibia. To achieve the objective of the study, it was important to have it rooted in the pragmatism paradigm; followed by both the deductive and inductive approaches. Interviews were conducted with the six SME owners and structured questionnaires were completed by the seven staff of the selected bank. The study used thematic analysis to analyze primary data from interviews by following three steps namely: reducing the data referred to as coding, analyzing data by creating patterns, and generating themes and drawing conclusion. Data from self-administered questionnaires was populated and textually analyzed aided by tables. The main findings of the study were that: (1) debt financing contributed to the growth and performance of SMEs as all firms under the study who made use of debt had experienced growth in terms of generated profits and acquired assets, (2) during the assessment and approving process, the bank looked at various lending factors and that collateral was not considered as prime to accessing funding, (3) the SMEs were not sufficiently funded and that there was no appropriate funding option for SMEs, (4) in terms of relationships, there was a lack of engagement and support between the bank and the SMEs. The support received from the bank was only in terms of lending. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2023

  • Description: Knowledge-making in universities is not neutral and takes different forms. This thesis critically examines the politics of knowledge to propose and present a transgressive schema for knowledge-making that is co-created with students. It emerges from teaching and learning encounters in the Humanities Extended Studies (ES) Programme at Rhodes University, where for the past decade we have experimented with different ways of knowledge-making that run counter to conventional pedagogic practices. We set up a project for the thesis that allowed us to work with knowledge in ways that are Afrocentric, and that hold and nurture our dreams. The theory and methodology of the project are explained in the first academic paper for this PhD by publication. The project and its derivatives use an African Feminist framing, and centre the ontoepistemologies of African young people who find themselves alienated and marginalised by a western bias in university curricula. Former ES student volunteers came up with topics, responded to them, reviewed each other’s work, and co-wrote two academic papers that demonstrate a praxis of African Feminist research and pedagogic principles. Two further projects practise the principles that emerge from the primary project, and together they have tested knowledge-making cultures that inspire critical thinking and creative humanity. These are explained in two further academic papers. One is co-written with the copresenter of an online inter-continental short course for PhD students on African Feminist Research Methodology. The other is single authored, and introduces the third project, a Political and International Studies third-year course on African Feminist theory. The schema for knowledge-making uses the hand, which holds our dream, as a descriptive metaphor. Each of the five fingers of the hand represents an aspect of how we have collaborated on the projects and in lecture rooms, and what this has taught us about how to nurture and inspire the dreams of young African people through transgressive knowledgemaking cultures. The five aspects – framing, activating, seeing, creating, imagining – are mutually constitutive elements of knowledge-making that are introduced throughout the thesis, and explained in careful detail in the conclusion as a synthesis of the collaborations. , Siphethe amaphupha ezandleni zethu: ukwenza iinckubeko zolwazi ezigxile ekuphazamiseni isiqhelo Isishwankathelo Ukwenziwa kolwazi kwiiunivesithi asiyonto engathathi cala kwaye yenzeka ngeendlelangeendlela.

  • Description: This study focuses on the development of the sono-photodynamic combination therapy (SPDT) activity of phthalocyanines (Pcs) on the cervical and breast cancer cell lines in vitro. The SPDT technique utilizes ultrasound in combination with light to elicit cytotoxic effects for cancer eradication. In this work, a selection of tetra-peripherally substituted Zn(II) cationic and zwitterionic Pcs were prepared. The photophysical parameters of the Pcs were determined including their fluorescence behaviours and efficiency of the triplet excited state population. The effects of the ultrasonic parameters (frequencies (MHz) and power (W.cm-2)) on the stability of the Pcs were evaluated. Four parameters were evaluated: Par I (1 MHz: 1 W.cm-2), Par II (1 MHz: 2 W.cm-2), Par III (3 MHz: 1 W.cm-2) and Par IV (3 MHz: 2 W.cm-2). The stability of the Pcs reduced with the increase in the ultrasonic power (for Par II and Par IV). The Par I showed the least degradation compared to the other parameters and was therefore used for the SPDT treatments. The sonodynamic (SDT), photodynamic (PDT) therapy activities of the Pcs were studied and compared to their SPDT efficacies. The Pcs showed reactive oxygen species generation during the SDT, PDT and SPDT treatments. For the SDT and SPDT, singlet oxygen (1O2) and hydroxyl radicals (•OH) were detected. For PDT, only the 1O2 were detected. The cell cytotoxicity studies for the Pcs showed relatively higher therapeutic efficacies for the SDT treatments compared to the PDT treatments, where the SPDT showed higher therapeutic efficacies compared to both the SDT and PDT monotreatments on both the cell lines in vitro. Overall, the combination treatments were better compared to the monotreatments. The activities of the Pcs were compared by their differences in structures, including the type of R-group, type of quaternizing agent and type of nanoparticle conjugates. , Thesis (PhD) -- Faculty of Science, Chemistry, 2023

  • Description: This thesis investigates Zimbabwean’s immigration to South Africa. Zimbabwean’s immigration to South Africa dates back to the early 2000s. This thesis uses a combination of theories to interrogate and discuss the Zimbabwe special permits and some of the post-apartheid government’s amendments to the South African Citizenship Act and other immigration policies. Some of the theories that theoretically underpin this research project’s methodology include Marxism, Pan-Africanism, Liberalism and culture-based theories. This thesis interrogates the discursive strategies these permits draw on to frame and understand Zimbabwean immigrants in South Africa. This study has found that these permits use similar operating logic as the White South African governments used the migrant labour system to exploit Blacks from all of Southern Africa in the 20th century. For instance, the migrant labour system used during apartheid made all Blacks in South Africa “guest workers” who could be deported at the government’s whim. The apartheid government used racist pass laws to regulate the movement of Black people in South Africa, whereas the post-apartheid government uses Zimbabwean special permits to regulate the movement of Zimbabweans in South Africa. The pass laws were fundamentally racist, and their ultimate objective was to reinforce the idea of White citizenship, whereas the Zimbabwe special permits are not racist. Their colonial similarity, however, lies in how they make Zimbabwean migrants perpetual migrants in South Africa and the various ways in which they cast Zimbabweans as not deserving of South African citizenship. These special permits force Zimbabwe migrants to become “guest workers” who build the post-apartheid economy and then return home when they are no longer “useful” to the economy. This thesis concludes that the post-apartheid Zimbabwe special permits achieve analogous objectives. , Thesis (MA) -- Faculty of Humanities, Political and International Studies, 2023

  • Description: While depression is experienced worldwide, the World Health Organization indicated that over 80% of this disease burden is found in low- and middle-income countries, with 16% of depressive disorder cases being found in Africa. Specifically, in South Africa, the lifetime prevalence of major depressive disorder is 9.7%. Research conducted on traditional healing estimates that as high as 80% of black individuals in South Africa choose to consult traditional healers. Although there was initial consensus that the use of traditional healers reflected a lack of access to alternative resources, more recent research has however indicated that traditional healers are consulted even when psychiatric facilities and medication are available. Research has illustrated that many patients that chose to consult traditional healers do so as a result of their shared beliefs, and traditional healers' ability to understand the cultural frameworks underlying illness. The current study investigated how traditional healers in the Eastern Cape perceive and treat phenomena currently understood as the symptoms of depression and how these understandings can be incorporated into collaborations between Western medicine and traditional healing practice. A qualitative research design was used to examine the perspectives and treatment methods of isiXhosa traditional healers in the Eastern Cape. Four healers participated in the study. Key findings indicated that there is no single cause or definition of the phenomenon of depression by healers. Causality is greatly attributed to spiritual causes and ancestors play a key role in guiding the diagnosis and multiple treatment interventions employed by healers to treat the experience of depression. Finally, all traditional healers expressed a willingness to collaborate and work with the Western healthcare system, however, they indicated a strong need for greater recognition as a valid healthcare system. , Thesis (MA) -- Faculty of Humanities, Psychology, 2023

  • Description: Land use change has increased in southern Africa as many livestock farms convert to game reserves, to restore degraded and overgrazed lands. This leads to a change in herbivore communities with potential positive and negative consequences for vegetation and landscape productivity. This study aimed to look at the effect of land use change and subsequent herbivore community changes, on thicket vegetation structure, composition, and landscape productivity. To attain the study objectives, data were collected from four game reserves and their adjacent livestock farms within the Eastern Cape province in South Africa. These sites were selected because they are within the Subtropical Thicket biome (similar vegetation) and were once used for livestock farming. At each study site, vegetation composition and structure were assessed using a unique bush clump sampling technique along fence line contrasts. Six plots were sampled at each site, three plots on the game reserve lands and three plots on the adjacent livestock farmlands during the dry (July/August 2020) and wet (January/February 2021) seasons. The Normalized Difference Vegetation Index (NDVI), in-situ leaf area index (LAI) and the fraction of intercepted photosynthetically active radiation (FIPAR), were used to assess vegetation productivity between the two land use types. Additionally, diet of an extralimital herbivore, giraffe (Giraffa camelopardalis), was assessed during contrasting seasons (dry and wet) to infer the role this species might have on these landscapes. The diet of giraffes was assessed through field observations, recording plant species that giraffes were feeding on. Floristic results showed that there were no differences in vegetation structure, species composition and richness between the two land types. There was no difference in the overall diversity of plant species on the game reserves than in the adjacent livestock farms. The primary productivity was greater on the game reserves compared to the livestock farms. Field observations of giraffe feeding showed that they fed predominantly on Vachellia karroo followed by Searsia longispina. Their diets did not differ between the two seasons. My study provides an insight into the effects of changing land use and this information can be used to infer the extent to which these changes might have on restoration of degraded landscape and how land use changes may be effective in restoring the degraded thicket vegetation caused by overgrazing and overstocking of domestic livestock. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2023

  • Description: Chromolaena odorata (L.) RM King and H Rob. (Asteraceae) has been subject to a biological control programme in South Africa for over three decades. A shoot-tip boring moth, Dichrorampha odorata Brown and Zachariades (Lepidoptera: Tortricidae), originating from Jamaica, was released as a biological control agent in 2013 but despite the release of substantial numbers of the insect, it has not established a permanent field population. Because climate incompatibility is a major constraint for classical biological control of invasive plants, and based on the differences in climate between Jamaica and South Africa and field observations at release sites, aspects of the thermal physiology of D. odorata were investigated to elucidate reasons for its failure to establish. Developmental time decreased with increasing temperatures ranging from 20 °C to 30 °C, with incomplete development for immature stages at 18 °C and 32 °C. The developmental threshold, t, was calculated as 8.45 °C with 872.4 degree-days required to complete development (K). A maximum of 6.5 generations per year was projected for D. odorata in South Africa, with the heavily infested eastern region of the country being the most eco-climatically suitable for establishment. The lower lethal temperature (LLT50) of larvae and adults was –4.5 and 1.8 °C, respectively. The upper lethal temperature (ULT50) for larvae was 39.6 °C whilst that of adults was 41.0 °C. Larvae thus had better cold tolerance compared to adults whereas adults had better heat tolerance compared to larvae. The critical thermal (CT) limits for adults were 3.4 ± 0.07 to 43.7 ± 0.12 °C. Acclimation at 20 °C for 7 days resulted in increased cold and heat tolerance with a CTmin and CTmax of 1.9 ± 0.06 and 44.4 ± 0.07 °C respectively, compared to the relative control, acclimated at 25 °C. Acclimation at 30 °C improved neither cold (CTmin: 5.9 ± 0.08 °C) nor heat tolerance (CTmax: 42.9 ± 0.10 °C). These results suggest that thermal requirements fall within field temperatures and are thus not the main constraining factor leading to poor establishment of D. odorata in South Africa.

  • Description: The South African Broadcasting Corporation (SABC) is mandated as the public broadcaster to provide news content in all South Africa’s official languages. While this has been a challenge on traditional broadcast platforms, online resources, such as social media pages, present an opportunity for the SABC to support the creation and sharing of content in African languages. With relatively little national news and current affairs content available online in indigenous languages, this study investigates the way that SABC News online offerings in the isiZulu language have the potential to contribute to public debates in terms of Habermas’ concept of a public sphere and its adaptation to the online domain, taking into consideration scholarly critiques of its suitability in the African context. The SABC News Current Affairs programme Yilungelo Lakho serves as a case study to examine the potential for the SABC to share African-language news content online. The programme is broadcast primarily in the Nguni languages, and the online audience on Facebook often choose to respond in isiZulu or other African languages. Semi-structured indepth interviews were conducted with three members of the production team and three contributors to the Facebook page. A textual analysis of Facebook posts across 13 episodes, with a total of 497 comments from 306 online contributors highlights the manner in which online interaction promotes or hampers the inclusion of isiZulu speakers in SABC News and Current Affairs discussions, rational deliberation on the SABC Current Affairs programme, and fragmentation and overlap across different online platforms. While multilingual interactions on the Yilungelo Lakho Facebook page make for complex curation, the findings suggest the need for African language content to support public discussions and point to an opportunity for the public broadcaster to fulfil its mandate. , Thesis (MA) -- Faculty of Humanities, School of Journalism and Media Studies, 2022

  • Description: Over the last few years, there has been a notable increase in popularity in the use of cannabidiol (CBD) as a form of alternative medicinal treatment for various illnesses. CBD, a by-product of the cannabis plant, is an isolate and does not contain the psychoactive agent, tetrahydrocannabinol (THC). Endometriosis and Polycystic Ovarian Syndrome (PCOS) are chronic reproductive health sicknesses that are increasingly experienced by women. In the absence of cures, biomedical treatment for these diseases aim to manage symptoms, for example; heavy bleeding, heightened levels of pain, and insomnia. CBD offers an alternative to women who feel that biomedical interventions are no longer able to maintain their health and well-being. CBD positions itself as a natural remedy claiming to be safe and effective. This research study, mainly through qualitative data collection, focused on experiences of Zimbabwean and South African women living with endometriosis and/ or PCOS, who have turned to CBD to manage their symptoms. The importance of this study was to position itself within patients’ lived experiences. The research study found that CBD indeed has numerous benefits, including pain management, alleviating stress, and anxiety. Through the emergent themes from the data, it became clear that women are marginalised and treated unequally in the biomedical healthcare sphere. Feminist Anthropology and Structural Violence was applied to analyse the data collected to explore the patriarchal nature of the biomedical healthcare system and the experiences that women have, which has led them to turn to alternative treatments. , Thesis (MSocSci) -- Faculty of Humanities, Anthropology, 2022

  • Description: Unemployment is a long-standing and pressing socio-economic phenomenon that affects, markedly, both developed and developing countries. Although, in one way or another, many people are affected by unemployment, the reviewed literature concurs that youth unemployment is a critical component of the overall unemployment challenge. Indeed, the burden of unemployment is borne, tremendously, by young people, especially those who are Not in Education, Employment, or Training (NEETs). The International Labour Organisation (ILO) has declared youth unemployment a global crisis, with approximately 67,6 million unemployed young people worldwide in 2018. In South Africa, the youth unemployment rate escalated to 56.4 per cent in the second quarter of 2019. This disturbing level of unemployment among young people poses a serious threat—for as long as young people stay unemployed. Indeed, the cost of unemployment is too high, not only does it engender discontent among young people who are floundering in poverty and frustration, but it can also trigger or perpetuate all sorts of social, political, and economic effects. These effects only exacerbate the already intricate and onerous global agenda of tackling unemployment— because they give rise to other socio-economic ills (e.g., crime, among others) that also need to be addressed. Owing to this grave and perpetual challenge of unemployment, exploring and understanding the dynamics of youth unemployment continues to be of paramount importance worldwide. This thesis, in particular, seeks to investigate the factors that impede on the employment of the NEETs category, as it may be extremely difficult for them to enter the labour market— and they may lose hope of entering the labour market later in life, if they are unsuccessful while still young. Unlike graduates or other youth categories (i.e., matriculants) who have better chances in the labour market, some young people (by virtue of being ‘dropouts’, teenage moms/dads, having failed matric, among other reasons), remain the most vulnerable to unemployment. For this reason, the primary aim of this thesis is to examine the ways in which employers’ recruitment strategies advantage or disadvantage young people (NEETs). The secondary aims include: (a) examining how employers' perceptions and attitudes, regarding the NEETs youths, influence their recruitment decisions when it comes to employing young people; and (b) understanding the ways in which government strategies (devised to combat youth unemployment) influence employers’ decisions to recruit the youths’ or not. In essence, this study seeks to explore the demand-side factors in the labour market that can help us understand how employers’ recruitment decisions (or recruitment behaviour) affect the employment prospects of young people in the labour market. The focus on demand-side factors is motivated by Labour Market Segmentation (LMS) theories, which serve as the theoretical framework of this thesis. LMS theories’ significance lies in their opposition to neoclassical economics, that posit the existence of a unified labour market (which operates like all other markets), consisting of buyers and sellers in ‘free’ competition. According to neoclassical theory, the difference between workers’ employment and wages is determined by ‘individual preferences’ and investments in ‘human capital’ (skills, experience, formal education, etc.). By contrast, LMS theorists argue that labour markets are fragmented, and that differences on the demand side imply differences in compensations that are not totally determined by individual workers' human capital. Inspired by the claims of LMS theories, this study elected to explore demand-side factors by applying qualitative research methods and techniques to gather and analyse the data gathered, and to ultimately address the research objectives. In particular, non-probability sampling was used to sample 20 firms from four sectors (manufacturing, retail/hospitality, finance, transportation) in the Johannesburg (CBD) region. The respondents were all asked a series of semi-structured questions in order to yield qualitative results that would help determine the employers’ dispositions towards young people; and about the government’s strategies that address youth unemployment. The aim is to provide an in-depth, nuanced understanding of how the respondents’ dispositions influence the inclusion or exclusion of young people in the employers’ recruitment considerations. The aggregate results of the study generally indicate that—although there are innumerable factors that affect young peoples' employment prospects—young people (without skills and tertiary education or matric) are actually being employed, and are still being considered for employment by the majority of the sampled employers (predominantly from retail/hospitality firms). Only a minority of employers stated, categorically, that they do not employ young people, and do not intend to do so. Conversely, the results also reveal that the the majority of employers often recruit young people for general and entry-level jobs that are often offered on a non-standard employment basis. At face value, the employment of young people (without skills) in the majority of the sampled firms may seem to make a difference—and it probably does, for as long as young people are exposed to the world of work. However, in the 4 grand scheme of things, the kind of employment offered in these firms is also problematic, because it is, basically, transient and unsustainable. As such, the young people that occupy these jobs are most likely to find themselves back in the unemployment queues whenever the ‘part-time’ or ‘temporary’ employment contracts are terminated. These jobs are especially problematic because policies such as the National Development Plan (NDP) 2030—in line with Sustainable Development Goals—aim to reduce poverty by creating sustainable employment. Contrarily, these kinds of jobs make it hard to achieve poverty reduction, because they are inherently unsustainable and barely lift people (especially young people) from unemployment and poverty. Based on these results, it can be asserted that the proliferation of non-standard employment compromises the agenda for decent work, and it delays the already sluggish Sustainable Development goal of creating sustainable employment (among other goals). This, then, reveals that there is still a stark and long-standing need for more radical strategies that will ensure the creation of sustainable jobs—without which the unemployment crisis will be far from over. Moreover, the results further indicate that the reasons why the minority of the sampled employers do not employ young people boil down to the fact that young people usually do not have what employers look for in their potential recruits; or that young people do not have what employers believe will contribute to the growth and productivity of their firms. In essence, employers will never employ any young person (or any jobseeker in general) that will be a liability than an asset in their firms. Over and above, this thesis corroborates many of the explanations—encapsulated in the growing literature—for rising unemployment, as well as the claims that unemployment is highly pronounced among young people. However, the contribution of this thesis is that it further offers a nuanced view to understanding the demand-side factors (as additional determinants) that hinder the employment of young people (especially those who make up the NEETs category). , Thesis (PhD) -- Faculty of Humanities, Sociology, 2022

  • Description: The purpose of this investigation was to add a scientific element to the understanding of run out opportunities in T20 (twenty/twenty) formats, which would in turn, provide recommendations to players and coaches around the topic of run outs. Due to a lack of research in this field, the study was two-fold, as there is little research known on this topic. Firstly, surveying experienced coaches on what they would expect to take place during run out opportunities from different areas of the field in a T20 game. Secondly, the study looked at what happened during successful and unsuccessful run outs from different areas of the field in two Indian Premier League (IPL) seasons. The aim of the study was to determine what variables, within an area of fielding, led to a successful or non-successful run out from different zones in the field. Coaches were required to fill out a survey which asked them to give their expectations on run out opportunities during a T20 competition. The data from the questionnaire would be used to gain a greater understanding of the way coaches understand different characteristics of run outs and whether this matched the findings of the second part of this study. The second part of the study investigated run out opportunities in two consecutive IPL seasons, based on video footage, looking at how different variables impacted successful or marginally missed run out opportunities in different areas of the field and at different times of the game. The areas were put into four different zones. Zone 1 being close to the batter, zone 2 being in the inner ring, zone 3 being on the edge of the ring and zone 4 being boundary fielders. Most of the coaches believed that in zone 1 of the field, the bowler would have the most opportunities, where in fact, based on the video footage, these fell to the wicket-keeper. In zone 2 there were a larger range of fielding positions (10) that run outs fell to when analysing video footage. The coaches supported this by often naming the same fielding positions. There was a divide in zone 3. Most run out opportunities from the video footage came to extra cover, where most coaches didn’t believe that would be the case and rather mentioned mid-off and mid-on. When analysing video footage in zone 4, it had two fielding positions (long on and deep mid-wicket) make up the majority of run out chances in this area and these two positions were quoted by most of the coaches as having the most run out opportunities fall to them. Throughout the findings, as concluded from the video footage, there were some results that matched the coaches’ expectation and some results where findings from the video footage differed from the coaches’ expectations. These findings are all useful. Firstly, it validates coaching practices. Secondly, it provides coaches with greater insight as to where they aren’t getting it correct in their fielding training. In conclusion, this study found that although coaches perceptions, for the most part, matched what took place on the field, there were instances where we saw the opposite action take place. This has important practical implications for coaching and practice. , Thesis (MSc) -- Faculty of Science, Human Kinetics and Ergonomics, 2022

  • Description: This study is a socio-political aspect of Zimbabwean history. It examines the development of youth political violence starting from the late 1950s when violent forms of African political mobilisation emerged to 2018 when the first election without Robert Mugabe was held. It explores how early nationalist parties such as the Salisbury City Youth League (SCYL), Southern Rhodesia African National Congress (SRANC), National Democratic Party (NDP), Zimbabwe African People’s Union (ZAPU) and later the Zimbabwe African National Union (ZANU) mobilised and socialised youths into political violence to understand the roots of the violent political culture in Zimbabwe. This study shows that youths were an important part of the strategies of these political parties in countering the violence of the colonial state as well as mobilising mass support for the movements during the liberation struggle. It reveals that war collaborators (mujibhas and chimbwidos) were central role players in instigating political violence against innocent and defenceless people during the war. In the 1980s and 1990s, the Youth brigades and the ZANU-PF Youth League became a key constituent for state-socialist developmental goals but they were at times manipulated as a resource for political violence when Mugabe’s power was challenged. The study shows that more grotesque violence occurred in the 2000s era when the National Youth Service (NYS) was introduced and state-sanctioned vigilante groups like Chipangano in Mbare emerged in response to the rise of the Movement for Democratic Change (MDC) and diminishing of consensual power. This study argues that youth were not mere victims and perpetrators of political violence, but they were a collection of various interest sub-groups with diverse agendas and a sense of agency. Some joined violent groups for their social mobility, power, impunity and economic opportunities availed to the group members. Data for this study was drawn from Mbare and Highfields (in Harare Province) and Uzumba-Maramba-Pfungwe (in Mashonaland East Province). , Thesis (PhD) -- Faculty of Humanities, History, 2022

  • Description: The main objective of this thesis is to investigate how conscious hip hop culture is used to reconstruct and influence urban youth identities in South Africa, in the case of Fingo Village, Makhanda. In addition, it aims to understand how the South African conscious hip hop scene, appropriated from the West, can be used to shape the identities of the urban youth, instead of the materialistic commercial/mainstream gangsta rap that is currently dominating popular culture and media today. Kellner’s (1995: 10) multicultural critical approach is appropriate for this thesis, as it “provides a critical multiculturalist politics and media pedagogy that aims to make people sensitive to the relations of power and domination which are encoded in cultural texts, such as those of television and film, or new technologies and media such as Internet, and social networking”. Moreover, in the words of Cvetkovich and Kellner (cited in Dolby, 2010:11), this dissertation “investigates the increasing influence of global popular culture and its possibility to equip the urban youth with new sources of identification”, as well as opportunities for social change. In Makhanda, rappers, community activists, B-Boy crews, graffiti artists, spoken-word poets, photographers, and journalists all assembled in Fingo Village for the social event Around Hip Hop, at the multipurpose Fingo square, between 2011 and 2019. Today, Around Hip Hop is an arts based organization that produces hip hop mixtapes, short documentaries, and educational events aimed at creating a cross-cultural exchange and increasing awareness of South African politics. Around Hip Hop has hosted various events, dialogues, and performances where hip hop is used as a cultural expression, which continuously creates spaces for the urban youth to rethink and reconstruct their identities; not only as artists, but as audience members as well. Events, such as The Return of the Cypher, Intyatyamo Elityeni, and Business beyond Fingo Festival all form part of Around Hip Hop. The Return of the Cypher is an open music event, where rappers, usually gathered in a circular formation with one or more artists performing in the middle, showcase their skills. Semi-structured interviews were conducted with eight local hip hop artists in Makhanda, in order to investigate how conscious hip hop is used to rethink and reconstruct urban youth identities. , Thesis (MA) -- Faculty of Humanities, Sociology, 2022
