- Description: A change champion has been defined as a person from any level of the organisation who is skilled at initiating, facilitating and implementing change, and who can effectively champion organisational changes. From a review of the literature, it was anticipated that change champions may experience role conflict, due to the multiple roles that they needed to fulfil simultaneously. Informed by organisational role theory, this research investigated the change management programme of a specific public entity as a case study, and analysed the nature of the role conflict that change champions experienced during a specific organisational change. Semi-structured interviews were conducted with four change champions, the change coordinator and the Executive Director Corporate Services. The organisational documents that relate to change management were also consulted with a view to providing background information and an overview of the change management programme. A deductive thematic analysis approach was used to analyse the data. A coding framework was developed prior to the collection of data, and was used for the identification of theoretical codes and themes in the data. The following codes were developed and explored as types of role conflict: role ambiguity, person role conflict, role strain, role overload and role incompatibility. In terms of the findings, this study confirmed that change champions did experience role conflict during organisational change, mainly due to various expectations that come from different role senders. In the light of these findings, it was recommended that senior managers could reduce the incidents of role conflict by training change champions, introducing an orientation programme for new change champions, consider their personal values when appointing them, and allocating sufficient time for change champions to fulfil this additional role. This study has contributed to the body of knowledge by drawing on role theory and applying it to change management, in order to provide insight on the role of change champions during the organisational change, and in particular the role conflict that they experienced.

- Description: This thesis presents a series of three case studies from data collected as part of a research project exploring the process and impact of a service-learning programme with caregivers and their children with neurodevelopmental disabilities. Following a descriptive case series design, both quantitative and qualitative data are presented to create a comprehensive and rich understanding of each case. In particular, the data tracks change processes in the subjective well-being of the caregiver, the quality of the caregiver-child relationship and the functional development of the child over a twenty-one-week period of receiving public health services and an eight-week period of adding the service-learning programme. The paper also presents qualitative data on the caregivers’ perceptions of and experiences of the public services and the servicelearning programme that the caregivers and their children received. The findings provide important insight into the caregivers’ perceptions of giving and receiving care, with the caregivers’ experiencing significant levels of distress and prominent barriers to accessing healthcare that were seemingly eased with the addition of the service-learning programme. The findings also point to a notable disparity between the quantitative findings and the qualitative interviews with questions being raised about the research being viewed as an intervention in itself.

- Description: There has been a significant increase in the prevalence of Ransomware attacks in the preceding four years to date. This indicates that the battle has not yet been won defending against this class of malware. This research proposes that by identifying the similarities within the operational framework of Ransomware strains, a better overall understanding of their operation and function can be achieved. This, in turn, will aid in a quicker response to future attacks. With the average Ransomware attack taking two hours to be identified, it shows that there is not yet a clear understanding as to why these attacks are so successful. Research into Ransomware is limited by what is currently known on the topic. Due to the limitations of the research the decision was taken to only examined three samples of Ransomware from different families. This was decided due to the complexities and comprehensive nature of the research. The in depth nature of the research and the time constraints associated with it did not allow for proof of concept of this framework to be tested on more than three families, but the exploratory work was promising and should be further explored in future research. The aim of the research is to follow the Hybrid-Malware analysis framework which consists of both static and the dynamic analysis phases, in addition to the digital forensic examination of the infected system. This allows for signature-based findings, along with behavioural and forensic findings all in one. This information allows for a better understanding of how this malware is designed and how it infects and remains persistent on a system. The operating system which has been chosen is the Microsoft Window 7 operating system which is still utilised by a significant proportion of Windows users especially in the corporate environment. The experiment process was designed to enable the researcher the ability to collect information regarding the Ransomware and every aspect of its behaviour and communication on a target system. The results can be compared across the three strains to identify the commonalities. The initial hypothesis was that Ransomware variants are all much like an instant cake box consists of specific building blocks which remain the same with the flavouring of the cake mix being the unique feature.

- Description: Corporate Social Responsibility (CSR) requires companies to fulfil certain responsibilities in society that are outside of the core operational activities of the company. The socio-economic dynamics of the region or country that the company operates from, as well as the pressures those stakeholders tend to apply, have a bearing on the direction that the CSR development takes. Mirvis and Googins (2006) described the CSR developmental path followed by international companies. Before that Carroll (1991) had suggested a developmental pyramid that suggested that philanthropy represented the highest level of CSR development. This pyramid was later revised by Visser (2005) in order to suit the African environment. In South Africa CSR development is mainly driven by legislation through the BEE Act of 2003. This has resulted in the birth of industry charters that guide the development of CSR in different industries. To fulfil the requirements of the charter and score vital B-BBEE points, companies have to engage with both internal and external stakeholders, holistically. One such industry is the telecommunications industry, which formed the basis for this research, with special emphasis on the mobile telecommunications industry. The research set out to explore how the industry charter and company practices compared with the existing literature on CSR. The aim of this research was therefore to analyse the existing CSR practices in the mobile telecommunication industry in South Africa, where the B-BBEE Act plays a pivotal role in influencing practice. Using publically available documents, this research conducted an analysis of the B-BBEE components in the telecommunications charter as the catalyst to development of CSR in the South African mobile telecommunications industry, with the three dominant companies, - MTN, Vodacom and Cell C – being utilised as case studies. Key research findings were that transformation is still low in terms of equitable gender and racial representation at the top management level. The industry charter attempts to address these and other social challenges and economic problems. However, it does not address ecological issues that may emanate from the industry operations. Therefore, a CSR assessment framework that addresses all stakeholders for sustainable economic development is proposed.

- Description: This study forms part of a larger project investigating attitudes towards intimate partner violence, dating violence and other forms of gender-based violence with the Rhodes University context. The primary purpose was to establish a baseline descriptive understanding of participants‟ attitudes towards and perceptions of gender-based violence. With the aim to generate results that would somehow inform the larger project, the current study sought to investigate whether a relationship exists between gender-role ideology and attitudes towards gender-based violence amongst a university population which was inclusive of registered students and employees of the university (n = 308). Four samples were categorised: student sample, academic staff sample, administrative support staff sample and operational support staff sample. A once-off, cross sectional survey design was used to obtain the data. The results of the study revealed that the participants in the study uphold largely non-traditional gender-role ideologies, are generally intolerant of dating violence and are rejecting of rape myths. As predicted in the literature, the study revealed that demographics such as gender, religion, age, level of education, number of years spent in the institution, race, and student accommodation have an impact on the relationship between adherence to traditional gender-role ideology and tolerance towards dating violence, as well as on the relationship between adherence to traditional gender-role ideology and rape myth acceptance and the relationship between rape myth acceptance and tolerance towards dating violence. The study contributes to the growing body of knowledge on gender-based violence in institutions of higher learning and could help improve sexual violence prevention programmes in such contexts.

- Description: The sugar cane industry has for many years been a lucrative business with a booming global market. In Zimbabwe, the sugar cane industry is no exception, as it has been regarded as one of the most efficient in the region and even in the world. The sugar cane farms and mills in Zimbabwe are located in Triangle and Chiredzi, in the south-eastern part of the country and they are under the ownership of Tongaat Hullet and the Zimbabwean A2 farmers. The focus of this is on the A2 fast track farms in Hippo Valley, which are now owned by black farmers but as out-growers for Tongaat Hullet. The crucial question addressed in the thesis is whether the A2 sugar cane farmers and their workers, located at the production end of the sugar cane global value chain, are benefitting from their involvement in this value chain. A number of scholars argue that global value chains lead to economic and social upgrading at the production end of the chain, based on thoughts contained in modernisation and trickledown theory. There is an assumption, then, that integration into the global economy leads to economic upgrading which translates into social upgrading. In drawing upon critical global value theorists, bolstered by the Marxist perspective, considers the importance of a more critical view of global value chains in relation to the sugar cane industry in Zimbabwe, with the particular focus on A2 farms. Thus, the main objective of the thesis is to consider the lives and livelihoods of A2 sugar cane farmers and sugar cane workers through a case study, in the context of global value chains and arguments around economic and social upgrading. This is pursued through a case study of six A2 farms, which involved interviewing farmers, supervisors, and both permanent and temporary workers. The thesis concludes that there is no significant evidence of social upgrading amongst the labour force, and that the A2 farmers are in constant tension with Tongaat Hullet in seeking to engage in economic upgrading of their status as commercial farmers.

- Description: For a number of decades now, development non-governmental organisations (DNGOs) have been central to the world-wide development system which involves funding from international donors. Overall, DNGOs rely quite fundamentally on their donors for organisational sustainability, such that upward accountability to donors is inevitable. At the same time, as development agents, DNGOs are often celebrated for the deep participatory methodologies used when engaging with the beneficiaries of their programmes, leading to significant downward accountability – as least potentially. Often, for DNGOs, an awkward tension between upward and downward accountability exists. This thesis considers this tension by examining a DNGO in South Africa, namely, the East Cape Agricultural Research Project (ECARP), which focuses on questions around land redistribution. ECARP works with farm labourers and dwellers on commercial farms and small-scale farmers on redistributed farms. In the context of a broader understanding of ECARP’s mission, capacities and programmes, the thesis looks specifically at ECARP’s food security and sovereignty programme amongst small-scale farmers on redistributed farms. By drawing upon Interface theory, the thesis discusses in detail the diverse manner in which ECARP uses participatory methodologies in this particular programme. The thesis concludes that there is a reasonable degree of downward accountability in this programme, but that this does not distract from the fact that ECARP remains within the tension-riddled space marked by dual demands for accountability.

- Description: Learning is a process that involves building on prior knowledge, enriching and exchanging existing understanding where learners’ knowledge base is scaffolded in the construction of knowledge. Research on the teaching and learning of geometry in mathematics suggests that physical manipulation experiences, especially of shapes, is an important process in learning at all ages. The focus of the study was the migration of Grade 8 learners from one Van Hiele level to the next as a result of teachers incorporating visualisation processes and Van Hiele phases of instructions in their teaching. The study underpinned by the social constructivist’s theory, therefore aimed at teachers developing visual materials and using Van Hiele’s phases of instruction to teach two dimensional figures in Geometry. The study was carried out in Namibia, Zambezi region in Bukalo circuit. It involved four schools, with 93 learners and three teacher participants. The research is an interpretive case study of a planned intervention programme, which took a four weeks to complete. Participating learners wrote a Van Hiele Geometric test prior and post the intervention programme to determine their geometric level of thought. Participating teachers all received training on visualisation in mathematics and the Van Hiele theory before the intervention. During the intervention, teacher planned and each taught three lessons on two-dimensional figures. Qualitative data was collected from classroom observation, stimulus recall interviews and focus group interviews. Quantitative data came from the pre and post-test of learners. This study found that on average, Grade 8 learners who participated in the study were operating at levels lower than expected of pupils at their stage of schooling. This study also found that, visualisation processes and the Van Hiele phases are effective when used in geometry lessons to migrate learners from lower Van Hiele levels to higher. For teachers in the same circuit, partnership and planning of difficult topics on an agreed regular basis is recommended. When planning lessons teachers are encouraged to take advantage of the Van Hiele phases of instructions. This study thus recommends the incorporation of visualisation strategies of teaching geometry in particular at primary and lower secondary levels. Mathematics teachers are further encouraged to design visual materials such as Geoboards to use for every topic in geometry. Such visual materials should be carefully developed and evaluated to ensure that their use in the classroom is effectively linked to concepts under discussion in a given lesson.

- Description: Based on a broad literature review, understanding algebra is a challenge among learners in middle schools around the world. Early researches also indicated that algebra is often taught through inherent symbols and procedures. This does not exclude Namibian learners in secondary schools whom I have worked with for over 10 years. Examination reports (2014, 2016 and 2017) serve as evidence that learners performed poorly (below 45%) in the area of algebra, with these reports indicating that teachers need to strongly emphasise the issue of solving linear equations. Therefore, this study presents a proposed design research in an attempt to help learners develop meaningful understanding of linear algebra at Grade 8 level. Eight learners whose ages ranged from 13 - 14 years from one Namibian secondary school in Oshikoto region, in northern Namibia, were the participants in this study. The learners represented different groups of learning abilities, ranging from low learning abilities to high learning abilities. The designed programme for this intervention consisting of eight lessons was planned for three weeks and the lessons were conducted in the afternoon to avoid any interruption with normal learning hours. The study used four tools for data collection, namely, benchmark tests (pre-test and post-test), observation, focus groups and unstructured interviews. The data collected for this study was inductively analysed. The purpose of this study was to determine whether and how the specific visual and kinaesthetic teaching tools (diagrams, expansion box and balance method) used may have contributed to learners’ understanding of algebraic concepts and techniques (variables, expressions and equations). The study used diagrams (geometrical plane shapes) for separating terms, an expansion box for expanding brackets and the balance method for solving linear equations. The study revealed the use of diagrams helped the learners in understanding the separation of variable and constant terms when simplifying expressions through addition and/or subtraction. Moreover, the study also revealed that the use of an expansion box was useful for the learners in understanding expansion of brackets in expressions with more than one term. Regarding the use of the balance method, the study showed that learners were already able to solve linear equations by the transfer method, hence, the balance method was not necessary.

- Description: With the increase in link speeds and the growth of the Internet, the volume of NetFlow data generated has increased significantly over time and processing these volumes has become a challenge, more specifically a Big Data challenge. With the advent of technologies and architectures designed to handle Big Data volumes, researchers have investigated their application to the processing of NetFlow data. This work builds on prior work wherein a scoring methodology was proposed for identifying anomalies in NetFlow by proposing and implementing a system that allows for automatic, real-time scoring through the adoption of Big Data stream processing architectures. The first part of the research looks at the means of event detection using the scoring approach and implementing as a number of individual, standalone components, each responsible for detecting and scoring a single type of flow trait. The second part is the implementation of these scoring components in a framework, named Themis1, capable of handling high volumes of data with low latency processing times. This was tackled using tools, technologies and architectural elements from the world of Big Data stream processing. The performance of the framework on the stream processing architecture was shown to demonstrate good flow throughput at low processing latencies on a single low end host. The successful demonstration of the framework on a single host opens the way to leverage the scaling capabilities afforded by the architectures and technologies used. This gives weight to the possibility of using this framework for real time threat detection using NetFlow data from larger networked environments.

A historical sociolinguistic study on the conceptualisation and application of justice and law kwisizwe samaXhosa as documented in and extracted From SEK Mqhayi And W.W. Gqoba’s selected writings

- Description: This study seeks to investigate the original meanings contained in lexical terms relating to law (umthetho) and justice (ubulungisa) and their application in the precolonial Xhosa social society as they make appearance in SEK Mqhayi’s novel Ityala lamawele (1914) and WW Gqoba’s Isizwe esinembali, (1873-188/2015). Both of these works were written and initially published at the early point of contact of amaXhosa with the art of writing, and so are set in a ‘traditional’ setting (in the case of Mqhayi) and at early contact with European societies in Eastern Nguni region. This academic endeavour is undertaken by employing critical discourse theoretical framework. The purpose is to investigate the conceptualisation of law and justice amongst amaXhosa, and the extent to which this conceptualisation reflects the philosophical worldview of amaXhosa, as embedded in their language. The paper makes inferences about conceptualisation of law and justice in precolonial Xhosa social settings, and offers proposals on what this conceptual understanding could mean if its potential contribution to the contemporary understanding and application of law and justice in South Africa could be tapped into. The motivation for this study emanates from the current intellectual contestations in higher education that today’s curricula present western knowledge systems as universal while marginalising indigenous epistemologies in teaching, learning and research practices. At the centre of these debates is how research, social and scientific thinking in humanities, is profoundly shaped by imported, racist, western “canonical” texts and theories. The arguments presented by various scholars argue that this enterprise firmly roots the collective imagination of students about the past and present in racist Eurocentric schematic frames, thus creating a problem of identity loss, and an intentional distortion of historical truths. The space for knowledge systems and experiences reflecting African memory and imagination is not only neglected, but distorted too. In this context, the study seeks to delve deeper into how African languages can be used to reconstruct knowledge systems that reflect African ways of understanding society as part of creating a curriculum that depicts “multiversal” ways of knowing (Tisani 2000; Santos, 2014). This study makes several findings, chief amongst which is that the legal and justice systems of the precolonial Xhosa society was both corrective as opposed to today’s punitive court system that South Africa inherited, largely from the West. It seeks to prove that AmaXhosa’s precolonial legal and justice system was focused more on reintegrating the offender back into society. The study further will show how the precolonial amaXhosa justice system was embedded in the concepts of ubulungisa (correct and re-intergrate) and isohlwayo (that which brings one to basics). Through discourse analysis of the early literary isiXhosa texts, the thesis discovers that the application of ubulungisa amongst amaXhosa back then was consistent with the philosophies embedded in the concepts. By exposing the collaboration networks between the white missionaries and the colonial administrators of the nineteenth century, the thesis will show how conspiracies were directed at erasing and displacing these indigenous epistemologies and to replacing them with colonial memories. To this end, missionary accounts, explorer diary entries and reports and early lexicographic material were produced and archived. Furthermore, this study makes a proposition that early written Xhosa texts be entrenched in the today’s curricula in order inform the process of making sense of the social experiences and knowledge systems of the indigenous people of South Africa, from the precolonial-past to the present. Throughout the study, the thesis presents a proposition these early Xhosa texts be studied in relation to their intellectual contributions. This, it is hoped, will boldly challenge the canonised knowledge and racist assumptions about the African knowledge systems and experiences.

- Description: In many parts of South Africa, complete allocation of surface water reservoirs together with current drought conditions has led to serious water shortages and subsequent awareness regarding the importance to save water. Grahamstown is no different, with water problems relating to low supply and high demand being compounded by insufficient treatment capacity and aging infrastructure. Groundwater is an alternative water resource that could potentially act as a supplementary and/or emergency supply to the town, reducing the reliability on surface reservoirs. Groundwater however, is a hidden resource and requires an understanding of various aquifer properties and continuous monitoring and modelling so not to permanently disrupt the natural system but rather achieve sustainable management. Grahamstown is situated towards the northern extent of the Cape Fold Belt (CFB) system, within a synclinal fold structure. The local geology forms two local aquifer systems beneath Grahamstown that directly influence both the dynamics and quality of the groundwater. These underground reservoirs are the Witpoort and Dwyka aquifers and can be described as a semi-confined, fractured, quartzitic sandstone aquifer and an unconfined, fractured, tillite aquifer, respectively. Separating these aquifer systems is a shale aquitard, although due to the fractured nature of the rocks in the region there is most likely some groundwater interaction between them. Evaluation of geological formations together with the monitoring of 31 local boreholes presented a valuable conceptualisation of the local system and allowed for the application of methods to estimate recharge. Recharge estimation is one of the most crucial factors when managing aquifer systems as it can be used to determine what proportion of rainfall contributes to the subsurface reservoir and therefore, the sustainable amount that can be extracted. Various methods have been developed to estimate recharge, however due to the uncertainty surrounding groundwater systems, especially fractured aquifers, it was important to apply multiple methods to validate results. The water-table fluctuation (WTF) and cumulative rainfall departure (CRD) are two methods that were used in the present study to determine recharge. These methods rely on water-table changes in boreholes and specifically how they respond to rainfall events. Along with the WTF and CRD methods, a modelling approach was also used to estimate recharge which focused on the dynamics of a natural groundwater outlet, termed the Fairview Spring. This natural spring system is located just outside the main town of Grahamstown, within the Witpoort aquifer system, and is an important water resource to many residents due to poor supply and quality of municipal water. Monitoring the discharge of this spring allowed for the development of a model which attempts to recreate the discharge conditions observed. Along with groundwater recharge, other processes added to the model include evapotranspiration, storage, interflow spring outflow and groundwater outflow. Several different model simulation scenarios provided valuable insight into the greater groundwater dynamics. In terms of groundwater quality, nine borehole samples and one spring sample were analysed for major ions (Ca, Na, K, Cl, Mg, SO4, HCO3), metals (Cu, Fe, Mn) as well as pH and electrical conductivity. Overall electrical conductivity levels and major ion concentrations were lower in the Witpoort aquifer indicating a better groundwater quality compared to that of the Dwyka aquifer. Of the three metals included in the analysis, Mn proved to be the most significant and the highest concentrations were produced for samples that intersected the shale aquitard unit, suggesting that Mn-containing groundwater is drawn from this geological layer. Development of a supplementary and/or emergency groundwater supply requires careful consideration of the geology, quantity, quality, and recharge in the study site. All these aspects were assessed as well as deliberation into the potential infrastructural costs involved. Through conceptualisation of the system; evidence gathered during basic monitoring; and a simple spring model, the current study aimed to explore certain management strategies and recommend potential options going forward. The hidden nature of the resource together with the heterogeneity of fracture networks creates an inevitable uncertainty surrounding the system. Proper development and management of the aquifer can only be achieved if the system is continually monitored, modelled and utilised sustainably.

- Description: The 2011 revision to the scope of practice of counselling psychology in South Africa has renewed debates about what is it that should distinguish counselling psychology as a distinctive area of practice and research in South Africa. This study reports the findings of a survey of a sample of 228 South African registered counselling psychologists, including the extent to which they endorse the traditional values of their category, the extent to which they endorse the current scope of practice for counselling psychology, and measures of career satisfaction. Findings are that women and white practitioners comprise the large majority of the category. Counselling psychologists strongly endorse most of the traditional values of the category and are generally highly satisfied with their careers. Surprisingly, given these findings, only a large minority indicate that they would choose counselling psychology again knowing what they know now. Most significant, the findings of a multiple regression analysis indicate that endorsement of the scope of practice most strongly predicts career satisfaction scores, followed closely by black racial identification, years of experience, and then endorsement of counselling psychology values. Logistic regression analysis to predict which counselling psychologists would choose counselling psychology again knowing what they know now, revealed that only endorsement of counselling psychology values and endorsement of the scope practice made a significant contribution to predictions. This study provides a snapshot of the current status of South African counselling psychology today and it remains that in the next ten years, there will be significant changes as the category changes across the globe.

- Description: This is a phenomenological study designed to investigate English teachers’ understandings of the concept of English Across the Curriculum (EAC), and the extent to which such understandings inform their pedagogic practices at the Senior Primary phase, in a Namibian context. The study was located within the qualitative, interpretive paradigm, using a multi-method approach of semi-structured interviews, classroom observations and documentary evidence as research instruments. The participants were three English second-language teachers at a primary school in a suburban area. Findings from the study revealed that there were several understandings of EAC, and though there might have been an underlying understanding of the concept, classroom practices were incongruent with what EAC requires. It was also found that there are documents based on social constructivist and Genre Theory in the National Professional Standards for teachers, but teachers were not familiar with the content of these documents and they were not used by teachers as guiding documents on how they need to implement EAC. It is recommended that English teachers receive continuous professional development courses on language development theories and EAC, as well as specific training to implement EAC so that “every teacher can be a language teacher”.

- Description: Very Long Baseline Interferometry (VLBI) has significant advantages in disentangling active galactic nuclei (AGN) from star formation, particularly at intermediate to high-redshift due to its high angular resolution and insensitivity to dust. Surveys using VLBI arrays are only just becoming practical over wide areas with numerous developments and innovations (such as multi-phase centre techniques) in observation and data analysis techniques. However, fully automated pipelines for VLBI data analysis are based on old software packages and are unable to incorporate new calibration and imaging algorithms. In this work, the researcher developed a pipeline for VLBI data analysis which integrates a recent wide-field imaging algorithm, RFI excision, and a purpose-built source finding algorithm specifically developed for the 64kx64k wide-field VLBI images. The researcher used this novel pipeline to process 6% (~ 9 arcmin2 of the total 160 arcmin2) of the data from the CANDELS GOODS- North extragalactic field at 1.6 GHz. The milli-arcsec scale images have an average rms of a ~ 10 uJy/beam. Forty four (44) candidate sources were detected, most of which are at sub-mJy flux densities, having brightness temperatures and luminosities of >5x105 K and >6x1021 W Hz-1 respectively. This work demonstrates that automated post-processing pipelines for wide-field, uniform sensitivity VLBI surveys are feasible and indeed made more efficient with new software, wide-field imaging algorithms and more purpose-built source- finders. This broadens the discovery space for future wide-field surveys with upcoming arrays such as the African VLBI Network (AVN), MeerKAT and the Square Kilometre Array (SKA).

- Description: The main aim of this research is to examine the hip hop scene in Grahamstown, Eastern Cape and whether hip hop can serve as a significant platform to discuss women’s lived experiences. This study also places focus on how female rappers construct their rap personas, as well as how they are perceived by their male counterparts. In order to understand the multifaceted viewpoints, it was necessary to interview both male and female hip hop artists. Eight interviews were conducted with eight young black rappers who are actively involved in the Grahamstown hip hop scene. It was found that hip hop, like any other art form, is a significant platform for women to express themselves, however gender constraints limit who is willing to listen to and promote their music. Male rappers advocate for women to talk about their stories, yet are more unlikely to listen because it does not relate to their struggles. In addition, there seem to be four specific tropes that female rappers choose to construct their identities from. Female rappers tend to create their personas around: Queen Mother, Fly Sista, Bitch with Attitude, and Lesbian. However, these categories are fluid and it was found that women navigate these categories depending on their audience and message they want to convey at a particular moment. Lastly, there is a split between Grahamstown West (Rhodes University) and Grahamstown East (township). University students are unlikely to perform in the township, and township residents rarely perform at organised events in Grahamstown West. In addition, Rhodes University students are more likely to feature on the university run radio station, rather than Radio Grahamstown, the local community radio.

- Description: Significant challenges exist in contemporary Zimbabwe with regard to urban government, including with specific reference to citizenship participation and service delivery capacities. One of the crucial factors considered in the existing literature when examining urban government is the extent to which the central government intrudes in the affairs of urban government. This is particularly important given that, in recent years, many urban governments have been controlled by the main opposition party in the country. In this context, the thesis offers a critical examination of urban government in contemporary Zimbabwe by focusing on urban government in Harare (the capital) and, even more specifically, on the high-density, low-income area of Glenview. Harare is one of two metropolitan urban areas in Zimbabwe, along with Bulawayo, and is governed by the Harare City Council. While the central state’s relationship with urban governments (including Harare) in Zimbabwe is important, and is examined in this thesis, the primary concern is how this and other factors affect citizenship participation and service delivery in Harare. In pursuing this, the thesis draws upon social capital theory (including questions around trust and networks) to facilitate a critical analysis of urban government, citizenship participation and service delivery in Harare and Glenview specifically. The fieldwork for this thesis involved a qualitative research methodology, including informal interviews with relevant local stakeholders in Harare and associated documents. The thesis concludes that localised political, social and other contextual factors in Harare undercut the prospects for meaningful citizenship participation (with forms of social exclusion existing) and that this has negative implications for effective and efficient service delivery mechanisms.

- Description: Using the theoretical framework of symbolic interactionism, this research sought to analyse and explore how Rhodes University students, both depressed and not depressed, understand depression, and how their understanding influences their interaction with people who do suffer from depression. For the purposes of this paper, eight participants were involved in an in-depth interview process. Out of the eight participants, six of them suffered from depression while the other remaining two participants had never suffered from depression, but they were close to someone who had depression. The findings of this research varied, some understood depression as a mental disturbance, others understood it as a condition that affects your emotions, and others understood it as a multifaceted condition that is highly subjective and cannot be understood using standardized measures. The participants’ personal experience and introduction into a new environment, in this context, university, changed their understanding of depression. The change in how they understood depression correlated with the change in how they interacted with depressed people.

- Description: The primary objective of this study was to understand to the role that discourse on traditional medicine plays in the choices that Rhodes University students and staff make regarding who they consult when they are sick. A secondary objective was to explore the participants’ views on the Department of Health’s draft policy on the institutionalisation of African traditional medicine and potential collaboration with the biomedical health care system. This was a qualitative study that used in-depth interviews and questionnaires to collect data, which was interpreted using thematic data analysis. A key finding was that participants were mostly influenced by their families with regard to the health care choices – either biomedical or traditional medicine. And that affordability, accessibility and availability are not important factors in health care choices as suggested by literature. Participants also based their decisions on what they believed would help them, either biomedicine or traditional medicine.

- Description: South Africa has a very high prevalence rate of HIV infections, this is why this exploratory qualitative study examines the Rhodes University’s HIV policy and its awareness programmes, with a specific focus on Pre-Exposure Prophylaxis (PrEP). The World Health Organisation’s (2016-2017) recommendations for Pre-exposure Prophylaxis has been accepted and rolled-out nationwide by the South African Department of Health. This is to maintain the HIV-negative status of not only the general public, but specifically students at higher institutions of learning. PrEP has been integrated with other HIV prevention methods through the Higher Education and Training HIV/AIDS programme. Semi-structured in-depth interviews were conducted with five female and four male students, and six health care staff members at Rhodes University. Data was thematically analysed, and the findings show that there is a lack of knowledge of both the HIV policy and Pre-Exposure Prophylaxis among the participating students. However, the staff members are knowledgeable due to the fact that they work in health care.
