- Description: In marine protected areas (MPAs), the radically open nature of marine ecosystems, the seemingly contradictory short-term goals of fisheries management (resource use) and conservation efforts (biodiversity protection), the variety of stakeholders, and the inherently political nature of space ha ve contributed to a disconnect between policy and practice. Many groups operate in an MPA at various spatial and socio-political scales, from national government bodies to local community groups, as such an MPA can be viewed as a complex, multi-scale and multi-level social-ecological system (SES). A greater understanding of the multi-scale processes driving the spatial resilience of SES can help address scale mismatches between continuous ecological change and the long-term governance of a seascape. South Africa has a long history of spaces and natural resources being politicised and faces high levels of unemployment and political frustration. Marine governance has been characterised as being siloed, lacking transparency regarding government processes and even between departments, and not properly addressing the needs of local communities; resulting in scale and level mismatches throughout the multi-scale processes (from national policies to local regulations)therefore, it is pertinent to understand the interactions between various national policies, their implementation, and their impacts. Using a spatial resilience lens, I set out to understand scale alignment in South Africa’s marine governance systems as it relates to MPAs. A spatial resilience lens emphasises analysis of both spatial and temporal scales, thus highlighting the multi-scale variables and interactions that occur within a system. I first sought to understand the policy and management across national and regional scales by conducting a series of semi-structured interviews with experts which were analysed using thematic analysis. I then approached the question of alignment from a local to national scale by using the Table Mountain National Park Marine Protected Area as a case study, here I carried out a series of workshops and interviews with line fishers, women’s groups, and eco-tourism operators from three different communities. Experts identified six themes when describing the structure of gove rnance in South African MPAs; they consisted of: government departments and marine legislation, management level factors, communication and information sharing, local level factors, biophysical factors, and scale. Communication and information sharing was the most mentioned referenced theme (40.26 %). The relationships between the communities and other actors (i.e. how communities are impacted, or impact on, the Department of Environmental Affairs , the Department of Agriculture Forestry and Fisheries, and Park Authorities) contributed 67.27 % to the total number of mentions, 91 % of which were from the following themes: communication and information sharing, local level factors, biophysical factors, and scale. My results indicate that weak, top-down relationships dominate the governance system in South Africa. During the Cape Town workshops I applied the spatial resilience lens in three ways. Firstly, the participants collaborated on a mapping exercise discussing the existing zone types within the MPA, as well as developing their own. There was an 87.87 % overlap of community designed zones on the existing MPA zones, however the types of zones designed by the community were different. Secondly, I carried out a document analysis and used information from the workshops to analyse the status and rights designation of important species for different user groups. The results show that the various stakeholder groups, while all active in the marine environment, interact with the ecosystem at different scales and with differing species. The differing interactions between groups result in challenges such as representation and complicated power dynamics between user groups. Finally, I asked participants to discuss factors that affect their ability to gain a livelihood from the sea. The external elements and their effects differed between the user groups, identifying important socio-political interactions. Whilst the external elements were all geographically distinct and localised, the spatial resilience lens allowed for a cross-scale, and to a certain extent cross-sector, understanding of these elements thus producing a more holistic understanding. My thesis shows that user groups operate on different spatial scales within the marine environment as a result of social, economic, and political influences leading to several scale-based challenges. The identified scale-based challenges have contributed to misalignments in marine governance in South Africa. My study shows that scale mismatches have important implications for understanding how marine policy influences user groups and identified pathways that affected policy implementation , and identifies future research application of a spatial resilience lens within social-ecological systems, for example it’s potential use in understanding the gendered nature of MPAs

- Description: The pedagogical practice choices teachers make when teaching writing in Grade-9 English first- language classrooms, as well as the extent to which these pedagogical practices appear to enable or constrain learners’ acquisition of writing skills as per grade-specific curricular expectations, are the focus of the study. It draws from Bernstein’s (1971) curriculum and society theory, as well as genre theory. Located within the qualitative case study approach, it is designed to investigate the reasons for Grade-9 English first-language learners’ underperformance in Paper 2, the composition component of the Namibian external examinations. Drawing from the interpretivist paradigm, the study uses one-on-one interviews, semi-structured classroom observations, as well as documentary evidence of the Namibian English first-language syllabus and examples of learners’ written work, to generate data. The research site and study participants were purposefully selected. The study involves two Grade-9 English first-language teachers and classrooms at one Namibian High School, and took place from the second to the third terms of 2017.

- Description: This research undertook an investigation in digital archaeology, modernisation, and revitalisation of the InetVis software application, developed at Rhodes University in 2007. InetVis allows users to visualise network traffic in an interactive 3D scatter plot. This software is based on the idea of the Spinning Cube of Potential Doom, introduced by Stephen Lau. The original InetVis research project aimed to extend this concept and implementation, specifically for use in analysing network telescope traffic. The InetVis source code was examined and ported to run on modern operating systems. The porting process involved updating the UI framework, Qt, from version 3 to 5, as well as adding support for 64-bit compilation. This research extended its usefulness with the implementation of new, high-value, features and improvements. The most notable new features include the addition of a general settings framework, improved screenshot generation, automated visualisation modes, new keyboard shortcuts, and support for building and running InetVis on macOS. Additional features and improvements were identified for future work. These consist of support for a plug-in architecture and an extended heads-up display. A user survey was then conducted, determining that respondents found InetVis to be easy to use and useful. The user survey also allowed the identification of new and proposed features that the respondents found to be most useful. At this point, no other tool offers the simplicity and user-friendliness of InetVis when it comes to the analysis of network packet captures, especially those from network telescopes.

- Description: A series of structurally related BODIPY dyes were synthesised and characterised. Their photophysical properties were studied in order to determine whether they would be suitable candidates for use as photosensitisers in the photodynamic therapy (PDT) treatment of cancer. The synthesis of two highly fluorescent BODIPY cores was achieved via the acid-catalysed condensation of a pyrrole and a functionalised aldehyde. In order to promote intersystem crossing, and hence improve the singlet oxygen generation of these dyes, bromine atoms were added at the 2,6-positions of the BODIPY core. These dibrominated analogues showed good singlet oxygen quantum yields, and excellent photostability in ethanol. In order to red-shift the main spectral bands of the BODIPY dyes towards the therapeutic window, vinyl/ styryl groups were introduced at the 3-, 5-, and 7-positions via a modified Knoevengal condensation reaction. The addition of vinyl/ styryl groups to the BODIPY core caused an increase in fluorescence quantum yield as well as a decrease in singlet oxygen quantum yield with respect to the dibrominated analogues. However, two of the red-shifted BODIPY dyes still showed moderate singlet oxygen quantum yields. The use of BODIPY dyes in nonlinear optics (NLO) was explored. The nonlinear optical characterisations and optical limiting properties of a series of 3,5-dithienylenevinylene BODIPY dyes were studied, both in dimethylformamide (DMF) solution and when embedded in poly(bisphenol A carbonate) (PBC) as thin films. The 3,5-dithienylenevinylene BODIPY dyes showed typical nonlinear absorption behaviour, with reverse saturable absorption (RSA) profiles, indicating that they have potential as optical limiters. The second-order hyperpolarizability (Y), and third-order nonlinear susceptibility (/m[/(3)]) values are also reported for these dyes. The optical limiting values of one of the BODIPY dyes in solution, and two of the BODIPY-embedded PBC films, were below the maximum threshold of 0.95 J-cm-2. The effect of addition of substituents on the electronic structure of the BODIPY dyes was investigated using TD-DFT calculations. The calculated trends closely followed those determined experimentally.

- Description: My writing contains elements of hard-boiled detective fiction and crime writing. My stories, written in isiXhosa and English and a mixture of both, transplant these genres into a South African township setting where gang violence dominates and life is cheap. They are driven by uniquely South African characters, brutal crime scenes and fear-inspiring suspense, but none the less still full of humour. I want my work to entertain the reader while also looking realistically and critically at the problem of crime in our townships. I draw on influences of African and Latin American writers to create South African crime fiction in a realistic urban setting, with dynamic characters and sharp dialogue. , Le ngqokelela yamabali iqulathe amabali angobomi babantu abasezilokishini nabo bahlala ezilalini.

- Description: The success of Nigeria’s 2015 general elections was unexpected, given the tense political and security climate in which the polls were conducted. It is against this backdrop that this study explores the contribution of four newspapers (The Guardian, Vanguard, Independent and Leadership) and, in particular, their editorials, to the relatively peaceful and mostly credible 2015 general elections in Nigeria. This qualitative study, located with an interpretivist tradition, draws on both in-depth individual interviews with editorial writers, and thematic content analysis of selected editorials to explore three themes: - violence-free polls, rational voting and credible electoral process. These newspaper editorials made moral and ethical appeals urging “supra-national” and patriotic attitudes as well as more detailed process interventions. Drawing from the theories of argumentation, the research suggests that three kinds (forensic, epideictic and deliberative) of arguments were made and three modes of argumentation (logos, pathos and ethos) were used by editorial writers to advance their arguments. This study examines what the editorial writers hoped to achieve and the normative ideals they drew on in the discharge of what they saw as their editorial duties. Drawing on theoretical insights from normative theories of journalism, and particularly social responsibility theory, this research posits that editorial writers hoped to arrest the spate of violence in the Nigerian polity, raise the level of discussion and redirect the attention of politicians in particular to core issues confronting ordinary Nigerians. The study finds a correlation between the editorials written and the normative ideals embodied in the social responsibility theory, which, the study finds, is the most influential normative ideal in the ‘mainstream’ Nigerian news media, at least in print. This study thus argues that in view of the range and frequency of focus on three core themes, and the persuasive power of writing, a case can be made for the editorials of these four major newspapers playing a constructive and positive role and making some contribution to the eventual peaceful and credible outcome of 2015 national elections in Nigeria.

- Description: E-governance is a comprehensive and well-thought out notion as it brings forth a change in the way governments communicate to citizens and to each other. Since the RSA government relies on regular consultations with the citizens in order to improve service delivery, e-governance approaches inspires citizens to be active agent of local democracy by means of providing information and participation on issues that matters the most to the society. The effectiveness of e-governance takes into account four systemic intentions which are as follows: Increased government accountability; Increased government transparency; Increased government efficiency and; Increased citizen’s trust In order for the RSA government, more particularly at the local level, to ensure quality of life to the citizens, the modernisation of government services and operations is very important. E-governance can now be considered as a source or tool for sharing ideas and initiatives that deliver a mutual enrichment. In other words, the citizens are the determining factor and actors for the rules and the role of the local bureaucrats as well as for the corresponding ICT tools persist to be developed. This treatise undertakes a strategic view and an evaluation of e- governance in local municipalities as the means of improving and transforming the delivery of services and access to information for citizens. Consequently this paper affords an exploratory analysis between e-governance and the six core elements of technology (i.e. e-strategy, e-skills development, e-services, IT governance and ICT infrastructure and e-leadership) believed to contribute positively in the effectiveness of e-governance. Finally, recommendations are made as a result of analysing the literature study and empirical study to ensure the implementation of the key initiatives of e-governance that can add value to the Nelson Mandela Bay Municipality (NMBM).
