- Description: The HIV and AIDS prevalence in Kenya is still high and remains a major health concern despite the Kenyan government’s initiatives to create awareness about the epidemic through inclusion of the HIV and AIDS programme in schools. This is because the provision of sexuality, HIV and AIDS education in schools is not effective. Teachers face various challenges in the effective delivery of the subject due to their discomfort related to these sensitive topics. Therefore, learners are left inadequately supported by the teachers. With an immense variety of conflicting information about sexuality availed to young people through the social media and also through their peers, young people are left at risk of exploring their sexualities with inadequate and wrong information, thus exposing them to HIV infections. Since schools have been identified as ideal sites for the effective delivery of sexuality, HIV and AIDS education, teachers are expected to teach the learners using a variety of pedagogical strategies in order to achieve efficacy in the delivery of this subject, hence the need to explore teaching styles that could provide a safe space for the effective delivery of sexuality, HIV and AIDS education. This study sought to explore teachers’ experiences of using participatory visual methods in teaching sexuality education within the HIV and AIDS education programme in selected Kenyan secondary schools, in order to understand how such methods could affect the teaching of Sexuality education. This study employed a phenomenological research design, interpretivist paradigm and a participatory methodology. Memory accounts, reflective journals and focus group discussions were used for data generation with nine secondary school teachers, from three purposively selected schools in Kenya. Vygotsky’s socio-cultural theory underpinned the study. The findings revealed that teachers are uncomfortable teaching sexuality education because of fear of leading learners astray, fear of victimization and sexualization, and fear of misleading and hurting learners because of lack of knowledge. This resulted in teachers feeling guilty due to ineffective delivery of Sexuality education. The findings also revealed that participatory visual methods were effective for use by the teachers and the learners in the classroom to navigate issues around sexuality, HIV and AIDS. This was because they are learner-centred, thus making learners producers of knowledge while at the same time encouraging optimism in teaching and learning. This study thus recommends pre-service teacher training on participatory methods of teaching. Educational institutions should also arrange for workshops to train in-service teachers on comprehensive sexuality, HIV and AIDS education and how to tackle it in their classrooms. Moreover, curriculum developers should make sexuality, HIV and AIDS education a compulsory subject to give it equal status with other examinable subjects, for it to be taken seriously. It is only through concerted efforts from everyone that Kenya can reach its target of Zero new HIV infections.

- Description: South African public schools in disadvantaged areas are experiencing serious levels of under resourcing which negatively impact the educational experiences of learners. Attempts to lessen such negative impact include involving alumni who know the school‟s context, history and ethos. Unfortunately, the concept of alumni support in terms of mentoring and motivating learners is not the norm in many under resourced schools. This research focuses on fostering partnerships with alumni using participatory action research (PAR), because it is holistic, relationally driven and inclusive. Embedded in complexity theory that views the school community as a nonlinear system of different interacting parts functioning to improve the school context, the research follows actionreflection cycles of a group of ten past pupils and five educators from various backgrounds, levels of education and expertise collaborating with and mobilizing other alumni. Data were generated using drawings, photo voice and interviews. Thematic data analysis was used to build patterns and form categories. The following themes emerged namely, the importance of establishing a collective vision for sustained alumni engagement for alumni‟s personal and professional aspirations to serve the vision of the school, the importance of creating an alumni culture that reinforces the concept of „paying it forward‟. Lastly, establishing a sustainable alumni association through sustained actions and interactions and by creating an organisation of excellence The newly developed alumni structure as a „resource fountain‟ generating and cascading energy around the school emerged as an anchor for sustainability. The cascaded energy evolved into a structured „Alumni Week‟ providing ongoing motivation for current learners to sustain alumni engagement.

- Description: The aim of this study was to explore and describe the intergenerational interactional patterns in a Coloured family where the mother has abused alcohol. Researchers have found that drinking behaviours of parents can have major effects on the children’s lives throughout generations. Substance abuse of a parent has major influences on the family, their interactions, and relationships, mostly between the parent and the child. There is a major gap in the study of the Coloured families and how substance abuse affects their families and children. The study employed Bowen’s constructs of differentiation of self, multigenerational transmission process, triangulation, emotional cut-off, nuclear family emotional system, sibling position, family projection process, and societal regression and utilized analytical generalization of the concepts to achieve its aim. The mother, an older sibling and maternal mother were the main sources of data although the perspective of the mother herself was privileged in the study. Semi-structured interviews were utilized to gather the data. This allowed participants to freely narrate their personal perceptions and experiences of interaction in both the family of origin and the current nuclear family. The research used a single case study of a purposively sampled family. The researcher is a Coloured female who had specific interest in this specific cultural group and their interactional patterns, which optimised cultural familiarity during the research process and reduced the likelihood of potential discriminatory racial bias of the participants. The findings demonstrate that perceptions of interactional patterns in the nuclear family and family of origin coincided with certain of Bowen’s Family Systems concepts, particularly, triangulation and differentiation. However, the need for further exploration of concepts such as the nuclear family emotional system and the family projection process in Coloured families are still needed in future studies. The findings provided insight into the functioning of the relationships and FAMILY INTERACTION IN MATERNAL ALCOHOL ABUSE interactions in both the nuclear family and the family of origin. Limitations of the current study are identified and recommendations for future studies in this field are also offered.

- Description: This thesis will analyse the ways in which fan participation and creation in online communities extends the film world beyond the film object, and the extent to which fandom influences identity within the fan group. The study will seek to determine the ways in which fans become part of the franchise through online engagement, as well as the manner in which they appropriate the franchise identity through their creations. The central hypothesis of the study is that online participation and creation amplifies fan connection with the film franchise, and increases the sense of identification with the world and characters of the films. By being or becoming fans, and engaging with other fans in online and real spaces, they are joining a larger community of people who seem to have blurred the lines between fiction and reality by engaging in a fictional, virtual space as a source of real personal entertainment, based on an anchor media product. This appropriation is enabled through digital communities which expand and extend the reach of fan interaction and further develop the identity of the individual as ‘fan’. Thus, the study will reflect on the implications of fan engagement with the film franchise in the digital space.

- Description: This study is focussed on female teachers teaching sexuality education in the HIV and AIDS curriculum in Zimbabwean urban secondary schools. In spite of the importance of education and HIV and AIDS education in preventing HIV infections, Zimbabwe secondary school Guidance and Counseling teachers are not engaging optimally with the current Guidance and Counseling, HIV and AIDS & Life Skills education curriculum, and hence, they are not serving the needs of the learners in the context of the HIV and AIDS pandemic. This study, therefore, explored the following research question with its set of secondary research questions: How can Guidance and Counseling teachers be enabled to teach sexuality education within the HIV and AIDS education curriculum suitable for the Zimbabwe secondary school context? What are Guidance and Counseling teachers’ understandings and interpretations of the current HIV and AIDS education curriculum in Zimbabwe secondary schools? What are Guidance and Counseling teachers’ values and beliefs that underpin their approach to teaching sexuality education within the HIV and AIDS education curriculum in Zimbabwe secondary schools? What do Guidance and Counseling teachers experience as challenges to teaching the necessary critical content in sexuality education within the HIV and AIDS education curriculum? How can Guidance and Counseling teachers be enabled to overcome the challenges they experience and teach the necessary critical content in sexuality education in the HIV and AIDS education curriculum? Eight female Guidance and Counseling urban secondary school teachers, conveniently and purposively selected from Gweru district in Zimbabwe, comprised the sample of participants. Situated within a qualitative research design, and informed by a critical paradigm, I used participatory visual methodology, with drawing and focus group discussion as methods for data generation. Participatory and thematic analysis was used to analyse the data which was theoretically framed by Cultural Historical Activity Theory, as a lens through which I explained the meaning of my findings. The findings, in four themes, revealed that the Guidance and Counseling teachers have an understanding of the Guidance and Counseling curriculum and made their voices heard on how it was designed but also how it should be designed, with whose input it should be designed and why, and how teachers should be supported in implementing it and ensuring that it is appropriate to the context in which they teach. The Guidance and Counseling teachers reflected on and reconsidered their own values and beliefs in relation to the values underpinning the sexuality education within the HIV and AIDS curriculum in order to fulfil their professional role in the context of the HIV epidemic. Even though the Guidance and Counseling female teachers were enthusiastic to teach sexuality education - in the age of HIV and AIDS - in the particular school and community context, they found themselves in an educational system that did not seem to support their work in an optimal way, and in a community with diverse cultures, cultural practices and beliefs of which some seemed to contradict what was supposed to be taught in the curriculum. The participatory visual methodology, however, enabled a process in which the Guidance and Counseling female teachers could reflect on themselves, the context in which they taught, their sexuality education work and also learn from each other. In this way their agency seemed to have been enabled to address the challenges and consider how they could teach sexuality education in their secondary schools in Zimbabwe. The findings have several implications for policy in terms of the Guidance and Counseling curriculum, resource mobilization, pedagogy, engaging with cultural issues, and supporting vulnerable children; and for practice in terms of teacher professional development, teacher training, and for stakeholder contribution. I therefore argue, drawing on Cultural Historical Activity Theory, that the Guidance and Counseling teachers could be enabled to teach sexuality education if the three Activity Systems, namely the Guidance and Counseling teachers, the school system, and the community, work together as one Activity System, engaging with each other in a generative way focused on the same outcome. The Guidance and Counseling teachers could therefore transform their realities if they are enabled to see how their teaching of sexuality education in school is linked to the context of the school and the culture of the community in which they teach and live, and engage with each other to achieve the same objective, namely teaching sexuality education in secondary schools in Zimbabwe, and in so doing enable the learners to make informed choices in the context of HIV and AIDS.

- Description: The research for this study was guided by the question on whether the financial inclusion improvement strategies of the South African government adequately address the financial inclusion targets, as set out in the National Development Plan. This descriptive non-empirical study was conducted by means of a literature review. The secondary data used for the study were collected from a number of sources, namely: (i) the 2015 Brookings Financial and Digital Inclusion Project report; (ii) the 2014 Global Findex survey; (iii) the InterMedia surveys; (iv) Financial Access surveys; (v) various national FinScope surveys; and (iv) a number of working papers of the World Bank related to financial inclusion. The data revealed that South Africa, with its sophisticated financial sector, was early to adopt policies and initiatives to advance financial inclusion and the country has experienced a noticeable increase in financial inclusion from 61% in 2004 to 87% in 2015. South Africa is 3% away from its National Development Plan goal of 90% financial inclusion by 2030. This indicates that overall, the financial inclusion initiatives adopted by the South African government were successful.

- Description: Although directives exist with respect to promoting sustainable development, financial strategies to cater for collective sustainable development, along with an increasing population, need to be formulated relevant to metropolitan and urban areas. This study determined the infrastructure investment basis of a sustainable city to investigate various funding mechanisms resulting in the design of a model for the financing of sustainable cities. For the study, first the various infrastructure investment alternatives were established from the literature, and thirteen themes and their relevant interventions were identified. Tangible and intangible methods of assessment were then identified as ways to calculate the acceptability of an intervention. A case study based on a hypothetical city was developed to determine the infrastructure investment base. Initially, only one intervention of a theme was populated and then confirmed by city development experts. Thereafter, all the themes were populated, and the acceptability of the interventions were determined. This provided an overview of the investment base of a sustainable city. The investment base facilitated deriving applicable tools and instruments to finance it. As a result, possible finance alternatives were derived for each of the identified themes. Although most of the financing of sustainable cities revolved around public sector finance, the private sector also played an important role for the financing of sustainable cities. Based on the investment base for sustainable cities and the resultant financing thereof, a model for the financing of sustainable cities was developed. The model consisted of four components. Firstly, the model included an application of financing tools and instruments relevant to the identified themes of sustainable city development. Secondly, the model included the application of financing tools and instruments with respect to an immediate interventionist focus, a facilitative focus, a gradual intervention and an enabling intervention. Thirdly, the model included financing tools and instrument types in terms of incentive, opportunity, punitive and mandatory interventions. Fourthly, the model included the application of financing tools and instruments with respect to scale in terms of a city-wide application, sector-wide application, urban application or suburban application. In addition, the model included the application of financing tools and instruments and their relation to addressing poverty within the city context. Although the public sector will always remain the key initiator behind infrastructure development, various mechanisms of financing, along with applicable financing partners and the basis of investment, are required to address future sustainable cities. This study may potentially form the basis of that platform.

The study makes use of quarterly macroeconomic time-series data sets comprising 84 observations, covering the period from 1994Q1 to 2015Q4. The unit root tests conducted employed the Augmented Dickey Fuller (ADF) and Phillips-Perron (PP) tests. The results reveal that the variables become stationary at first difference. The Johansen co-integration technique suggests that there is at least one co-integrating equation among the variables. The results of the Engle-Granger approach, which is residual based, show that the residuals are stationary, thus validating the existence of a long-run relationship between the model variables. The study carried out a Granger causality test. The results indicate that there is a strong Granger causal relationship between the variables (IF) and (FD). Another strong causal relationship emerges between inflation and money supply. The ECM model was employed to identify the speed of adjustment as a response to the departures from the long-run equilibrium path. The estimated coefficient of the ECM error term has the required sign and is statistically significant at the five per cent level of significance. The error term indicates a quick convergence to equilibrium. The study concludes that the dependent variable (FD) is jointly caused by all the independent variables in the long-run. The results of the variance decomposition of the variable (FD) to innovations resulting from IF, MS and RER indicate that own shocks remain the dominant source of total fluctuations in the forecast error of the variables. The findings of the study are efficient and reliable as the estimated model passed all the major diagnostic tests. By implication the findings suggest that the estimated model show high goodness of fit and is thus reliable for policy making. The study recommends a fiscal adjustment that will enhance economic growth. Additionally, a fiscal policy that will aim at identifying and mitigating other possible leakages that narrow the tax base should be considered.

- Description: Body size (Mb) determines an animal’s energy and water demands for thermoregulation. Sexual dimorphism in Mb is common across many species, but its physiological consequences (e.g. energy and water demands) remain poorly understood. In this study, I determined if the sexually dimorphic Cape Sugarbird (Promerops cafer)–males are up to 15% larger than females, show sex-specific foraging patterns and physiological responses. To determine intraspecific variability behavioural in response to temperature, I compared flower visitation rates between male and female Cape Sugarbirds at different times of the day, and among days that varied in maximum air temperature. A total of 1207 males and 561 females were observed. Female Cape Sugarbirds visited flowers more often and continued to feed especially on hot days. Males generally dominated flower resources throughout the day, except on hot days. I also compared physiological responses in EWL, RMR and Tb between males and females at high air temperatures. There were no significant differences between the two sexes. Aggression which was overlooked appeared to have a high influence on foraging behaviour of Cape Sugarbirds. These results suggest that female Cape Sugarbirds will be more prone to energy and water stress during hot and dry summers in the Fynbos region because of resource dominance by male Cape Sugarbirds. Endemic birds, such as the Cape Sugarbird, warrant a conservation priority, especially since they are the dominant pollinator of the Protea plants in the Fynbos biome. The findings of this study will provide insights into population persistence of Cape Sugarbirds in response to predicted heat waves and rise in global temperatures.

- Description: Marine top predators often occupy broad geographical ranges that encompass varied habitats. Therefore, a pre-requisite towards conserving these animals is to determine the components of their realized niche, and investigate whether a species is a specialist or a generalist. For generalist species, it is also necessary to understand if local specialisation occurs. Uncovering these components can allow us to build models of a species realized niche that may then be used to infer habitat use in unsampled locations. However, fully understanding the components of a marine top predators realized niche is challenging owing to the limited opportunity for in situ observations. Overcoming these limitations is a key step in marine top predator research. It will enhance our understanding of trophic coupling in marine systems, and aid in the development of tools to better study these predators in their dynamic environment. Seabirds, penguins (Spheniscids) in particular, are a group of animals for which investigating their realized niche is of vital importance. This is because numerous species face growing uncertainty in the Anthropocene, and in a time of rapid environmental change there is furthermore a need to better understand the potential use of these birds as indicators of ecosystem health. The aim of this thesis, therefore, is to investigate the foraging ecology of gentoo penguins (Pygoscelis papua) at the Falkland Islands. At the Falkland Islands, limited historical information exists regarding this species foraging ecology, with most information coming from a single location at the Falklands. As the Falkland Islands have the world’s largest population of gentoo penguins, elucidating factors influencing this population will have global relevance. Furthermore, historical information indicated potential competition with fisheries, and with prospecting for hydrocarbons and an inshore fishery, there is a need to understand the distribution of these birds across the islands. Penguins are also well suited to carry biologging devices allowing for in situ observations of inter and intraspecific interactions, as well as habitat specific interactions. In this study, I sampled birds over three breeding seasons, from four breeding colonies - chosen for their varied surrounding at sea habitat - across the Falkland Islands. I investigated the diet with stomach content and stable isotope analysis, the at-sea distribution with GPS and time depth recorders, and how these birds behaved at sea using custom made animal-borne camera loggers. Furthermore, I developed a method to recognise prey encounter events from back mounted accelerometers, using a supervised machine learning approach. As part of the first species specific description of diet at this scale for the Falklands, I revealed six key prey items for the birds: rock cod (Patagonotothen spp.), lobster krill (Munida spp.), Falkland herring (Sprattus fuegensis), Patagonian squid (Doryteuthis gahi), juvenile fish (likely all nototheniids), and southern blue whiting (Micromesistius australis). The use of animal-borne camera loggers verified that not only do gentoo penguins consume a diverse array of prey items, but they adopted various methods to capture and pursue prey, with evidence of birds following optimal foraging theory. Prey composition varied significantly between study sites with the at-sea distribution and habitat use of penguins reflecting that of local prey. Birds from colonies close to gently sloping, shallow waters, foraged primarily in a benthic manner and had larger niche widths. However, those at a colony surrounded by steeply sloping, deeper waters, typically foraged in a pelagic manner. Contrasting diet patterns were also prevalent from stable isotope data, and the niche widths of birds relating to both stomach content and stable isotope data were larger at colonies where benthic foraging was prevalent. Therefore, it was clear that surrounding bathymetry played a key role in shaping this species’ foraging ecology, and that at the population level at the Falkland Islands birds are generalists. However, at individual colonies some specialisation occurs to take advantage of locally available prey. I developed habitat distribution models - via boosted regression trees – which transferred well in time but poorly across space. Reasons for poor model transfer might relate to the generalist foraging nature of these birds and the reduced availability of environmental predictors owing to the limited range of these birds. I furthermore developed a method to identify prey encounter events that can also, to a degree, distinguish between prey items. This method will be a promising approach to refine habitat distribution models in future. These habitat distribution models could potentially contribute to marine spatial planning at the Falkland Islands. Footage from animal-borne camera loggers clearly showed that prey behaviour can significantly influence trophic coupling in marine systems and should be accounted for in studies using marine top predators as samplers of mid to lower trophic level species. Ultimately, flexibility in foraging strategies and inter-colony variation will play a critical role when assessing factors such as interspecific competition or overlap with anthropogenic activities.

- Description: The Eastern Cape Karoo region is semi-arid with highly variable rainfall. This variability in rainfall sustains a mosaic of surface freshwater bodies that range from permanently to temporarily inundated. These waterbodies provide habitats for diverse invertebrate assemblages. The imminent hydraulic fracturing for shale gas has a potential to modify the water regime, with particular risk of salinisation. Accumulation of salts in freshwater wetlands results in loss of biodiversity, as invertebrate species shift from salt intolerant to salt tolerant species. This study therefore aims to expand on existing knowledge and provide new information on the distribution, diversity and structure of macroinvertebrate assemblages associated with various freshwater bodies in the region prior to shale gas exploration. Limnological and ecological aspects of thirty-three waterbodies (rivers, dams and depression wetlands) were investigated between November 2014 and March 2016. An experimental study on the effects of salinity on hatching success of branchiopod resting eggs was also included in the research. Rivers were characterised by high conductivity and depression wetlands by high turbidity, while dams had relatively higher pH than the other two waterbody types. In terms of global phosphorus interpretation guidelines, the results indicate that freshwater systems in the study region are predominantly eutrophic, indicating that agricultural run-off, particularly from livestock dung (goats, cattle and sheep), is an important source of phosphorus in the freshwater systems studied. Our results revealed new distribution records for branchiopod crustaceans in the Eastern Cape region, including the first record of Laevicaudata. Results showed that the sampled variables were unable to explain the variation in physicochemistry and invertebrate assemblage of several sites. Waterbody type, whether a depression wetland or a river, was the only factor that consistently showed an effect on the composition of both physicochemical data and invertebrate data. Depression wetlands ranged from completely bare to being extensively covered by macrophytes. Therefore, the effect of macrophyte cover in structuring macroinvertebrate assemblages was the focus of further investigation. The results indicated that the macrophyte cover gradient had little influence on the structure of the invertebrate assemblages in the depression wetlands, while only the presence/absence of vegetation significantly influenced the structure of the invertebrate assemblages in these systems. Surface area, dissolved inorganic nitrogen and pelagic chlorophyll-a were the environmental variables that best explained the variation in the macroinvertebrate assemblages among the sites. However, the differences in macroinvertebrate richness, abundance and distribution patterns among sites were only weakly influenced by local and regional environmental factors. These findings suggest that invertebrate in temporary wetland systems are adapted to the highly variable nature of temporary habitats, thus the influence of local variables is negligible. Results of the experimental study, on the effect of salinity on hatching success of branchiopod resting eggs, revealed that hatchling abundance and diversity of large branchiopods was significantly reduced at salinities of 2.5 g L−1 and above. Salt-tolerant taxa such as Copepoda and Ostracoda were the only ones to emerge in the highest salinity of 10 g L−1. Thus, should the region continue to experience increasing aridity and possible shale gas development, which all aggravate the salinisation problem, severe loss of branchiopod diversity (Anostraca, Laevicaudata, Spinicaudata and Notostraca) is likely to occur. This may lead to considerable decline in invertebrate diversity in the region, with cascading effects on food webs and ecosystem functions. The findings of this study can potentially be used in comparative studies on wetland invertebrate ecology in other semi-arid regions and in the formulation of policy and strategies for biodiversity conservation.

- Description: The legitimacy of the judiciary is dependent on the racial and gender diversity of the courts. As a result of the oppressive policies imposed by the apartheid government, the High Court judiciary in 1994 was composed almost exclusively of white men. Judges were appointed at the behest of the executive arm of government and political considerations undoubtedly played a role in the selection process. As a result, the integrity of the judiciary was severely compromised in that the composition was entirely unrepresentative of the population it served, and they were appointed in order to further the strict racial policies of the apartheid government. The Constitution of the Republic of South Africa came into being through multi-party negotiations and is to form the basis of a complete transformation of the South African society. In a clear move away from the judicial appointments procedure of the past, the Constitution specifies that judges are to be selected by the Judicial Services Commission which is an independent body composed of members from all three branches of the government. In its selection, the JSC is guided by section 174(2) of the Constitution which requires that the racial and gender demographics of the judiciary must be considered when judges are appointed so as to make the bench broadly reflective of the South Africa population. Systemic discrimination of the past denied women the opportunity to gain the necessary knowledge and experience to be eligible for appointment to the bench. Special measures are therefore needed to advance women’s career path to the judiciary. In 2010, the Judicial Services Commission adopted selection criteria to be considered when shortlisting and selecting candidates to be recommended to the President for judicial appointment. Included in these criteria is the consideration of symbolism and potential. Special measures to advance persons who were previously disadvantaged by discriminatory practices are permissible in terms of section 9(2) of the Constitution. It recognises that true substantive equality will not be achieved without special measures aimed at remedying to disadvantage still felt by many people in South Africa, including women. The imposition of such measures does, however, have limitations. In the judiciary, specifically, demographic considerations can not be the primary consideration when judges are appointed. This could lead to a judiciary that is incapable to dispense justice to the population it serves because it does not have the required skill, knowledge and experience. On the other hand, if judges are appointed solely on technical merit, the judiciary is likely to remain male-dominated. The JSC therefore has to carefully balance the need for demographic transformation of the judiciary with the need to appoint technically competent judges. In Minister of Finance v van Heerden, the Constitutional Court laid down three requirements which remedial measures must meet in order to pass constitutional muster. Firstly, the beneficiaries targeted by the remedial measure must be persons who have been discriminated against in the past. Secondly, it must be designed to protect or advance previously disadvantaged persons. Lastly, the remedial measures must promote the achievement of equality in the long term. Once a measures meets all three of these requirements, it is not considered to be unfair discrimination against previously advantaged persons who do not stand to benefit from the measure in question. To safeguard the independence of the judiciary, judges are not considered to be employees of the state. This means that the provisions contained in labour legislation which requires the adoption of a formal employment equity plan when imposing affirmative action measures is not directly applicable to the appointment of judges. The Promotion of Equality and Prevention of Unfair Discrimination Act envisages the adoption of equality plans in all spheres not governed by labour legislation. These provisions are, however, not yet in force. As a result, there is no legislation that requires the Judicial Services Commission to adopt a formal affirmative action policy, and appointments made to address the gender imbalances on the judiciary are made on an ad hoc basis which runs counter to the test formulated in van Heerden. A related problem is that the Judicial Services Commission has not given sufficient content on the criteria needed for judicial appointment. For instance, even though the Judicial Services Commission does consider the technical competence, it has not published any guidance as to what is considered to be the minimum threshold of formal qualifications or experience needed to be appointed to judicial office. This has led many people to speculate that certain judges are appointed for ulterior purposes or, alternatively, that there exists some racial or gender bias within the Judicial Services Commission. This holds unfortunate consequences for the perceived legitimacy of the judiciary and strengthens the call for more structure and clarity in the appointment of judges.

- Description: In our technology- and information-infused world, cyberspace is an integral part of modern-day society. As the number of active cyberspace users increases, so too does the chances of a cyber threat finding a vulnerable target increase. All cyber users who are exposed to cyber risks need to be educated about cyber security. Human beings play a key role in the implementation and governing of an entire cybersecurity and cybersafety solution. The effectiveness of any cybersecurity and cybersafety solutions in a societal or individual context is dependent on the human beings involved in the process. If these human beings are either unaware or not knowledgeable about their roles in the security solution they become the weak link in these cybersecurity solutions. It is essential that all users be educated to combat any threats. Children are a particularly vulnerable subgroup within society. They are digital natives and make use of ICT, and online services with increasing frequency, but this does not mean they are knowledgeable about or behaving securely in their cyber activities. Children will be exposed to cyberspace throughout their lifetimes. Therefore, cybersecurity and cybersafety should be taught to children as a life-skill. There is a lack of well-known, comprehensive cybersecurity and cybersafety educational campaigns which target school children. Most existing information security and cybersecurity education campaigns limit their scope. Literature reports mainly on education campaigns focused on primary businesses, government agencies and tertiary education institutions. Additionally, most guidance for the design and implementation of security and safety campaigns: are for an organisational context, only target organisational users, and mostly provide high-level design recommendations. This thesis addressed the lack of guidance for designing and implementing cybersecurity and cybersafety educational campaigns suited to school learners as a target audience. The thesis aimed to offer guidance for designing and implementing education campaigns that educate school learners about cybersecurity and cybersafety. This was done through the implementation of an action research process over a five-year period. The action research process involved cybersecurity and cybersafety educational interventions at multiple schools. A total of 18 actionable guidelines were derived from this research to guide the design and implementation of cybersecurity and cybersafety education campaigns which aim to educate school children.

Gypsum deposits associated with the Whitehill Formation (Ecca Group) in the Steytlerville-Jansenville Area, Southern Karoo, South Africa

- Description: The Steyterville-Jansenville gypsum field is one of South Africa’s smaller deposits, yet plays host to several gypsum mines, both past and present. This study aims to deconstruct the processes involved in the precipitation of various quantities and grades of gypsum in the lower Ecca Group of the Karoo Supergroup. The calcium and sulphate ions required to form the gypsum mineral (CaSO4•2H2O) are derived from the mid- to lower-shale of the Whitehill Formation, which is carbonate- and pyrite-rich. Gypsum formation is dependent on the availability of pyrite as opposed to calcite, which is in abundance throughout the 30m thick, Early Ufimian (late Permian) Whitehill Formation. Weathered shale, which has been folded and faulted, forms the host environment in which gypsum has precipitated. Folding of the shale occurs as a series of large- and medium-scale anticlines and synclines that strike east to west. These structures, which formed during the Cape Orogeny indicate that stresses were exerted from the south-southwest towards the north-northeast. Folded calcite veins surrounded by amorphous pyrite, observed in thin section suggest that pyrite and calcite were precipitated together prior to a deformation event. Oxidation of pyrite following these deformation events results in the concentration of sulphides within the hinge zones of the folds (weakest zone) and this is where the larger gypsum deposits are found at the surface. Carbonate concretions in the Whitehill Formation up to 5m in length and 3m in width are common in the study area, and suggest a relationship with the deposition of the shale whereby calcium-rich nuclei grew in a concentric fashion during a non-depositional hiatus period. This period is also associated with a higher concentration of pyrite and could explain the occurrence of concretions together with adjacent gypsum-rich shale. Pyrite framboids observed under the Scanning Electron Microscope (SEM) provide evidence to suggest concentric growth of initially deposited microcrystals including nucleation and growth of nodules and concretions observed within the Whitehill Formation. Prerequisites for gypsum formation also include restricted drainage such as a pan, a clay layer in the drainage area and an arid climate where evaporation exceeds precipitation. The preferred surface conditions for gypsum formation would be low-lying areas which are surrounded by gently-sloping topography promoting the concentration of aqueous solutions in a calcite- and pyrite-rich area. Groundwater solution would initially dissolve the calcite and clay minerals, and pyrite and the quartz minerals would remain in the host rock. Areas with greater calcite and clay pores would accommodate more groundwater and thus promote a greater surface area for chemical reactions. This enhances the potential for the oxidation of pyrite to form sulphate ions, which can later combine with calcium ions to precipitate gypsum crystals. Alternatively, the oxidation of pyrite, which produces acidity, dissolves the carbonate host and the calcium- and sulphate-rich solution then precipitates gypsum. The combination of the structural and geomorphological processes is key to the formation of economic gypsum deposits. The potential for extensive gypsum reserves within the Steytlerville-Jansenville field remains valid, provided the target is located over a predominantly weathered Whitehill Formation outcrop, preferably in an area which has undergone extensive deformation (such as a fold hinge zone), and is favourable for the concentration of ground and surface water within a low-lying area.

- Description: The main aim of the analysis is to investigate the intermestic factors that led to political decay in Zimbabwe. By thoroughly assessing the dynamics of political development, one is then able to identify the factors that drive a state towards political decay. The study commences by delineating the domestic factors that contributed to the crisis in Zimbabwe. One unravels how the absence of democracy leads states to political decay. Democracy structured on effective institutions, good governance, transparency and a good relationship between civil society and the state are identified as being key factors that contribute towards political development. By assessing these factors meticulously, one is able to identify how disregarding them leads to political decay as evident in the case study. The study also explores how failed government policies can lead to political decay. Thus, ESAPs, the chaotic land reform program and corruption are discussed as being key contributing factors of political decay in Zimbabwe. The study makes use of interviews with 15 participants. The main objective of interviews in this study is to be able to compare the lived experiences of Zimbabweans vis a vis the information gathered from secondary sources. Also, by using thematic analysis on the gathered data, one will be able to unravel the participants’ perceptions regarding factors that led to stunted political development in the country. Contrastingly, the study seeks to explore whether domestic factors alone can be blamed for the crisis. One begins to question if external factors were also responsible for the crisis in the country. A closer look at the topic of discussion reveals that the AU, SADC and the EU also contributed to the crisis in Zimbabwe. Through the use of discourse analysis, one explores the reactions of the SADC and AU and how quiet diplomacy and the lack of a sterner response towards Mugabe led to an exacerbation of the crisis. Leaders who blatantly disregard the principles of democracy ought to be punished accordingly and not appeased, as in this case study. The EU sanctions on the country are also critically analysed and identified as being key contributors to the crisis. One ponders on whether they can be identified as a selfish response to protect EU interests in the country and punish Mugabe. By the end of the analysis it should be clear that both internal and external factors contributed to the political decay in Zimbabwe, as no country can live in complete isolation from other states in this global era.

- Description: In this study, I investigated the interaction between two megaherbivores, the African elephant and white rhinoceros, that has the potential to impact grazing lawns of which white rhino are the creators and maintainers and elephants are potentially the modifiers. I hypothesized that as elephants browse, they discard a variety of coarse woody debris onto the ground; should this woody debris (of varying amounts and sizes) fall onto grazing lawns, white rhino either move them, consume grass around the woody debris or abandon the lawn entirely. If high levels of woody debris are deposited here, grazing by white rhino is likely to be prevented, at which time I predicted that mesoherbivores would have a competitive advantage in accessing forage that white rhino cannot. I examined the mechanistic links between different levels of elephant-deposited woody debris and grass response at a point scale and feeding patch spatial scale of grazing lawns in an African savanna. In addition, I assessed the response of mesoherbivores in terms of vigilance behaviour with increasing levels of predation risk posed by increasing levels of woody debris. I present the first evidence of an indirect effect of elephant on white rhino foraging behaviour. I demonstrate how increasing levels of woody debris lead to a decreasing probability of foraging by white rhino. I also demonstrate how the probability of foraging by mesoherbivores increases as the amount of forage increases. However, since this study took place during a severe drought where resources are extremely limited, I was unable to properly separate the effects of elephant-deposited woody debris from the severe lack of rainfall on grass response and subsequently herbivore foraging behaviour. Due possibly to the drought, mesoherbivores responded less or not at all to risk factors such as woody debris therefore woody debris was not a predictor of vigilance behaviour in my study. This study contributes to our understanding of how the impacts of elephants, as ecosystem engineers, have cascading effects on savanna ecosystems. My study showed that elephant impact mediates the foraging behaviour of white rhino during a drought. However, under average rainfall periods, my original hypothesized effect of the indirect impacts of elephants on white rhino foraging and grazing lawn dynamics could still hold. This key hypothesis that I was unable to test under ‘normal’ conditions due to the drought is still valid and functionally important for understanding the ecosystem processes driving grazing lawn formation, persistence and composition in African savannas where elephants and white rhinos coexist.

- Description: Petroleum companies are critical to the Nigerian economy, as the petroleum sector is the biggest earner and spender of foreign exchange and the highest employer of labour. The industry is however faced with challenges of unprecedented fluctuation of commodity prices, exchange rates, a series of divestments, host communities’ demands, oil theft, project shelving, and destruction of infrastructure. Workforce cutting and consolidations are also the order of the day and current financial risk management (FRM) systems in companies appear not to be working. FRM systems in Nigerian petroleum companies have failed because risk managers did not have one generally accepted framework to manage financial risks such as fluctuations in commodity prices, exchange rates, interest rates, and in the demand and supply of crude oil and gas. There was a need for an integrated framework that is more descriptive and that does not rely only on mathematical models, separate management of each financial risk, and specific focus on the downside risk and derivatives. Mathematical models have presented weaknesses in the identification of issues, dissemination of information, policy formulation, planning, type and the institution of risk culture or delimitation of authority and in responsibility through the organisational structure. Mathematical models could not fully reduce the identification, communication, structure, and environmental scanning of FRM to mathematical models. The present study was the first attempt at an FRM framework that integrated all the financial risks strategically and took into consideration all the critical success factors that can solve the problems and challenges facing the Nigerian petroleum companies in the long term. The primary objective of the study was therefore to develop an FRM framework for the petroleum industry of Nigeria. The study collected data using a mixed methods approach to generate quantitative and qualitative data regarding financial risks facing the petroleum industry and possible methods of managing these risks effectively. The final sample consisted of 70 top-, middle- and lower-level managers, as well as five experts in the industry. Questionnaires were administered to practitioners in the south-eastern and south-western regions of Nigeria, and semi-structured interviews were conducted with financial risk management experts in the petroleum industry. Descriptive and inferential statistics were used in analysing the data. The study succeeded in developing a framework that: provides a thorough understanding and proper evaluation of the most important financial risks petroleum companies face; identifies the type and extent of top management support needed in a strategic FRM system; identifies and operationalises the financial risk culture that should be fostered to achieve FRM success; identifies the organisational structure that supports the successful achievement of FRM; identifies and operationalises the organisation communication flow that supports the successful achievement of FRM; identifies and operationalises oversight and control to support the successful achievement of FRM; and specifies the amount of training that supports the successful achievement of FRM. By implementing this framework, petroleum organisations in Nigeria will go a long way in successfully managing financial risks in that industry.

- Description: Post-colonial school curricula in Africa, which are mostly dominated by western values, knowledge and pedagogies at the expense of indigenous knowledge (IK) and epistemologies, remain a major area of concern in education. After decades of debate on the relevance of IK and its suitability for integration in school curricula, there appears to be a shift in paradigm towards recognising indigenous ways of knowing and transforming curricula towards using inclusive, contextual and practical content and pedagogies that reflect the changing needs of African society. Despite specific provisions in the South African and Kenyan constitutions and education policy documents, the development and implementation of IK integrated curricula remains a major concern. Teacher educators are important stakeholders in terms of the integration of IK and, as such, this qualitative study, which is framed within an interpretivist philosophical view and draws on a case study methodology, explores teacher educators‘ perceptions of value, place and position of IK in the school curriculum. The samples, which were drawn from two African universities, one in South Africa and one in Kenya, comprised ten purposively selected teacher educators from local indigenous communities in each university. Data were generated via a semi-structured questionnaire, a modified focus group discussion (Imbizo/Baraza) process, and individual semi-structured interviews. The data generated were analysed thematically and revealed that the participating teacher educators have shared conceptual understandings of indigenous knowledge and advocate for more inclusive appropriation and integration of indigenous languages, agriculture, herbal medicine, technological and scientific indigenous knowledge items that they feel are still marginalised in the school curriculum of their respective countries. An inclusive education approach was proposed in which both modern knowledge and IK are intertwined in the curriculum in order to serve the current needs of indigenous cultures and society in general.

- Description: The main objective of this study is to determine the impacts of internal service quality on customer satisfaction with specific reference to Department of Roads and Public Works Sarah Baartman Region (DRPW-SBR). The provision of high quality internal services to customers through policies and systems that support service delivery has a huge impact on customer satisfaction. Public organisations are generally criticised for service delivery inefficiencies and poor quality services; the DRPW-SBR is not an exception from such criticism. A study of this nature can be considered as a valuable undertaking that provides valuable insight as to the important internal service quality factors hindering DRPW-SBR from delivering services and satisfying customers. The study was specifically looking at investigating internal service quality dimensions as measured by the way of professionalism, responsiveness, tangibility, flexibility and reliability, play in the achievement of perceived customer satisfaction within DRPW-SBR. The research was set up in such a way that internal customers who were employees of DRPW-SBR and external customers who were employees of other departments served by DRPW-SBR, constituted the sample participants. The methodology considered most suitable was a quantitative research whereby questionnaires were utilised to collect primary data. The questionnaires were based on a five-point Likert scale measuring instruments that ranged from (1) strongly disagree to (5) strongly agree. Questionnaires were distributed to those respondents selected of whom 101 respondents participated; the results were calculated using a STATISTICA program. The key findings indicated that internal service quality played a vital role in achieving perceived customer satisfaction. Important internal service dimensions that were found to be significant in increasing perceived customer satisfaction within DRPW -SBR were reliability, flexibility and professionalism. Responsiveness and tangibility were found not to exert positive influence on perceived customer satisfaction within DRPW-SBR.

- Description: The main objective of this study is to determine the impacts of internal service quality on customer satisfaction with specific reference to Department of Roads and Public Works Sarah Baartman Region (DRPW-SBR). The provision of high quality internal services to customers through policies and systems that support service delivery has a huge impact on customer satisfaction. Public organisations are generally criticised for service delivery inefficiencies and poor quality services; the DRPW-SBR is not an exception from such criticism. A study of this nature can be considered as a valuable undertaking that provides valuable insight as to the important internal service quality factors hindering DRPW-SBR from delivering services and satisfying customers. The study was specifically looking at investigating internal service quality dimensions as measured by the way of professionalism, responsiveness, tangibility, flexibility and reliability, play in the achievement of perceived customer satisfaction within DRPW-SBR. The research was set up in such a way that internal customers who were employees of DRPW-SBR and external customers who were employees of other departments served by DRPW-SBR, constituted the sample participants. The methodology considered most suitable was a quantitative research whereby questionnaires were utilised to collect primary data. The questionnaires were based on a five-point Likert scale measuring instruments that ranged from (1) strongly disagree to (5) strongly agree. Questionnaires were distributed to those respondents selected of whom 101 respondents participated; the results were calculated using a STATISTICA program. The key findings indicated that internal service quality played a vital role in achieving perceived customer satisfaction. Important internal service dimensions that were found to be significant in increasing perceived customer satisfaction within DRPW -SBR were reliability, flexibility and professionalism. Responsiveness and tangibility were found not to exert positive influence on perceived customer satisfaction within DRPW-SBR.

- Description: The year 2015 marked a significant year in South African History and it ignited a deep desire in the hearts of locals in Port Elizabeth, Nelson Mandela Bay Metropolitan to question and engage with the city’s ambivalent heritage landscape and heritage discourse. The year 2015 was the year in which the country witnessed the rise community movements that called for the removal of Victorian and Apartheid era heritages across the country. The year also saw a rise in violent service delivery protests and a rise in the amount of xenophobic attacks across the county, including Port Elizabeth. In this thesis, positioned within the field of heritage studies (Anthropology) and employing the concept of the ubuhlanti (Kraal) as a tool to understand the former within a heritage framework. The thesis unpacks and demonstrate how the city centre of Port Elizabeth can be likened to the concept of the ubuhlanti. The ubuhlanti: an intimate community space, which has the potential to double up as an exclusionary space, excluding those who do not possess the necessary social capital to enter its centre.
