- Description: My thesis is a collection of poems that focuses on black mothering and motherhood, within the context of the Eastern Cape’s violent history, its oppressive patriarchal cultural traditions and religious structures. Drawing from my own experiences, my poems explore what Toni Morrison calls the historical ‘wounds’ of black women which are transferred to their daughters within everyday spaces like the kitchen and the lounge, through objects like tea cups, chair backs and the various foods that every black girl needs to be able to prepare in order to be ‘marriagable’, and how these continue to hurt and emotionally disfigure us. I also draw influence from Saidiya Hartman, Christina Sharpe and Tina Campt on black lives and the effects of slavery within their daily existences. And I am inspired by the intimacy and care with which Tadeusz Rosewicz writes about his relationship with his mother in Mother Departs and Sandra Cisneros’ use of interconnected vignettes to engage childhood, culture and community within marginalized space. Stylistically I am influenced by the structural innovations in Fred Moten’s The Little Edges and the dreamy landscape in the poetry of Federico Garcia Lorca. My collection includes prose and lyrical poetry, combining more formal sound and rhythmic structures with free verse, to bring to life motherhood and the narratives we carry from childhood into our adult lives.

- Description: This study investigates the importance of initiating career exploration discussions with young people from disadvantaged backgrounds, using the developmental-contextual framework of career development by Vondracek, Lerner & Schulenburg (1986). This model stresses the dynamic relationship between an individual, the ever-changing environment and how each influences the other. Based upon an earlier study by Spencer (1999), this study aims to explore the developmental-contextual model as the basis of successive group discussions at a pivotal moment in the lives of the youth from disadvantaged backgrounds. In addition, it aims to understand individuals’ perceptions of career education and the influences on career decision-making and aspiration. Data were collected through setting up and running a focus group session once a week over a period of five weeks, in which different career-related topics were discussed. The sample consisted of nine unemployed students who were currently not in a tertiary institution between the ages of 18-25 years. The findings indicated a noteworthy need for more relevant career interventions to be investigated and implemented for the diverse South African population. The study’s findings demonstrated that individuals might be more open to exploring career development through group rather than individual counselling. It was found that parents are the main career influencers in their children’s lives. Mothers were experienced as role models, supporters and encouragers while fathers were experienced as absent and unsupportive, playing little or no role in their children’s lives. The participants found this form of career exploration appealing as it allowed for peer consultation and the freedom to discuss career issues in a non-judgemental setting.

- Description: This work explores the synthesis and characterisation of novel symmetrical phthalocyanines and novel asymmetric porphyrins that have been embedded or linked respectively,and electrospun into fibres for application in the photocatalysis of environmental pollutants. The phthalocyanines contain pyrrole moieties without hetero atom linkers to maintain a rigid structure. The porphyrin contains a carboxy moiety utilized to construct an amide bond between the complex and the polymer prior to the spinning process. The new compounds were characterized by elemental analyses, proton nuclear magnetic resonance (HNMR)Fourier-transform infrared spectroscopy (FTIR), MALDI-TOF and UV-vis spectroscopy. The general trends of fluorescence, triplet and singlet oxygen quantum yields are described as well as their appropriate lifetimes. The photocatalytic activity of phthalocyanine embedded fibres were compared against those that had been dyed. Unfortunately, during the degradation process, the dyed fibres leeched compound and the studies could not be continued. It was seen that the porphyrin fibres linked to the polymer showed the most efficient photocatalytic activity against 4-cholorphenol and 4-nonylphenol due to irradiation at lower wavelengths consequently having higher frequencies and transferring more energy.

- Description: Traditional network segmentation allows discrete trust levels to be defined for different network segments, using physical firewalls or routers that control north-south traffic flowing between different interfaces. This technique reduces the attack surface area should an attacker breach one of the perimeter defences. However, east-west traffic flowing between endpoints within the same network segment does not pass through a firewall, and an attacker may be able to move laterally between endpoints within that segment. Network micro-segmentation was designed to address the challenge of controlling east-west traffic, and various solutions have been released with differing levels of capabilities and feature sets. These approaches range from simple network switch Access Control List based segmentation to complex hypervisor based software-defined security segments defined down to the individual workload, container or process level, and enforced via policy based security controls for each segment. Several commercial solutions for network micro-segmentation exist, but these are primarily focused on physical and cloud data centres, and are often accompanied by significant capital outlay and resource requirements. Given these constraints, this research determines whether existing tools provided with operating systems can be re-purposed to implement micro-segmentation and restrict east-west traffic within one or more network segments for a small-to-medium sized corporate network. To this end, a proof-of-concept lab environment was built with a heterogeneous mix of Windows and Linux virtual servers and workstations deployed in an Active Directory domain. The use of Group Policy Objects to deploy IPsec Server and Domain Isolation for controlling traffic between endpoints is examined, in conjunction with IPsec Authenticated Header and Encapsulating Security Payload modes as an additional layer of security. The outcome of the research shows that revisiting existing tools can enable organisations to implement an additional, cost-effective secure layer of defence in their network.

- Description: Visualisation is increasingly being recognised as having a significant role in the learning of mathematics especially when students are solving mathematical problems (Thornton, 2001). It is argued that visualisation is a powerful tool for learners to construct mental and physical representations that correctly mirror mathematical relationships and concepts. To gain a thorough understanding of the scope of visualisation, three Visual Technology for Autonomous Learning of Mathematics (VITALmaths) (www.vitalmaths.com) video clips were uploaded on mobile phones of each of the eleven participating student teachers who used them in their teaching practice. This is in cognisance of the educational potential offered by mobile phones and their current pervasiveness in the daily lives of both teachers and learners in Zambia (Zambia. Ministry of Education [M.O.E], 2013]). This study sought to investigate how VITALmaths video clips on mobile phones could be used by student teachers as a visualisation tool in the teaching of Number Sense. The videos of the lessons formed the core of my analysis. The study was conducted at four primary schools by eleven student teachers of a public university in Zambia. The study is framed as a case study and is grounded within the interpretive paradigm. The findings revealed that the student teachers’ use of the video clips in the classrooms for teaching was generally approached from two perspectives: at the beginning of the lesson or at the end. The videos were used at the beginning of the lesson as a means to introduce a topic or an idea, and at the end of the lesson to consolidate what was taught. The videos were also used to enhance the conceptual understanding of Number Sense. The findings also revealed that students encountered both enabling and constraining factors in their use of mobile phones to teach number sense. The overall findings revealed that, if well utilised, mobile phones as visualisation tools had the potential to enhance the teaching of Mathematics in general and Number Sense in particular, and therefore teachers should be encouraged to use them in their teaching.

- Description: A brief history of political correctness is discussed along with various definitions of it, ranging from political correctness being a benign attempt to prevent offense and avert discrimination to stronger views equating it with Communist censorship or branding it as "cultural Marxism". The aim of the research is to discover what political correctness is, how it relates to freedom of expression and what wider implications and effects it has on society. The moral foundations of rights and free speech in particular are introduced in order to set a framework to determine what authority people and governments have to censor others' expression. Different philosophical views on the limits of free speech are discussed, and arguments for and against hate speech are analysed and related to political correctness. The thesis looks at political correctness on university campuses, which involves speech codes, antidiscrimination legislation and changing the Western canon to a more multicultural syllabus. The recent South African university protests involving issues such as white privilege, university fees and rape are discussed and related to political correctness. The thesis examines the role of political correctness in the censorship of humour, it discusses the historical role of satire in challenging dogmatism and it looks at the psychology behind intolerance. Political correctness appeals to tolerance, which is sometimes elevated at the expense of truth. Truth and tolerance are therefore weighed up, along with their altered definitions in today's relativistic society. The last part of the thesis looks at South Africa's unique brand of political correctness, along with Black Economic Empowerment, colonialism and white guilt, and the research concludes that political correctness is a distinct form of censorship which has developed in modern democracies. The new forms of justice and morality seen in political correctness are distortions of left-wing liberalism, which appeal to different values to those of traditional liberalism.

- Description: This study examined the current plant diversity status and the impact of drivers of change on the peat basins of the Kromme River peatland. It was conducted at six sites over sixty one years in the Eastern Cape Province of South Africa. I reviewed the rapid habitat and biodiversity loss of wetlands globally and discussed the distribution of wetlands and specifically peatlands in South Africa. Plant species diversity was assessed using Modified- Whittaker plots. The influence of environmental variables on floristic composition and distribution was investigated using ordination techniques (DCA and CCA). Land use dynamics were assessed by applying GIS techniques on orthorectified aerial images. Six different peat basins were subjectively classified into good, medium and poor condition peat basins. The good condition peat basin (Krugersland) was the most diverse in plant species (4.1 Shannon-Weiner’s index) (p> 0.20; F = 11.04; df = 2), with the highest mean number of plant species (32.5 ± 3.4). This was followed by the medium condition class (Kammiesbos) (26.5 ± 9.0) and poor condition class (Companjesdrift) (22.5 ± 8.9). On average, species composition was not evenly distributed across the peat basins (p> 0.21; F = 0.94; df = 2), since 77.8% of the Shannon-Weiner evenness index obtained were less than one. However, there were variations in plant species richness across six peat basins as confirmed by Oneway ANOVA test (p= 0.0008, F = 1241.6, df = 4). Key environmental variables that influenced plant species distribution and structure were erosion and grazing intensity, potassium, phosphorus, soil pH and calcium. Total species variance accounted for in the first two axes for ground cover and plant height were 40.7% and 56.4% respectively. Alien species (e.g. Acacia mearnsii and Conyza scabrida) were common in degraded peat basins, whereas good condition peat basins supported indigenous species (e.g., Cyperus denudatus, Chrysanthemoides monolifera and Digitaria eriantha). Analysis of aerial images revealed a general progressive decrease in the peatland area between 1942 and 1969 in the good (Krugersland) and poor (Companjesdrift) condition class, with a marginal increase from 1969 to 2003. Peatland area in the good and poor condition class decreased by 5.3% and 8.3% respectively between 1942 and 1969, with a marginal increase of 1.5% and 4.1% respectively from 1969 to 2003. Annual net rate of change in peatland area over the 61 year period was -0.32% (good condition class) and - 0.79% (poor condition class). Transformed lands were impacted by drivers of change such as alien invasives, agricultural activities, erosion and sediment transport. The area under alien invasives increased by 50% between 1942 and 2003, with an annual net rate of change of +0.82 (good condition class) and +1.63% (poor condition class).

- Description: [Extract from message from Minister of Higher Education, Hon. Naledi Pandor]: It gives me great pleasure to endorse the 7th edition of Study South Africa. The International Education Association of South Africa (IEASA) has once again produced a publication that provides valuable insights and information about South African public universities and their place in the global higher education arena I welcome this publication and congratulate IEASA for its hard work in promoting our higher education institutions internationally. Study South Africa gives a comprehensive picture of higher education in our country. At a glance, the enquirer is able to see all that South African higher education has to offer diversity in terms of institutions, the wide range of affordable courses on offer, the international acceptability of South African qualifications as well as the rich multi-cultural experiences of our campuses. In short, the Guide provides a summary of everything that will assist the potential student to actualise his or her full potential. South African higher education is founded on broad social values such as respect for human life and dignity, commitment to equality and human rights, respect for diversity and nonsexism. Our education system seeks to construct citizens who are conscious of these values and therefore aware of their responsibilities in life and in the lives of others. These values are reflected in the diverse offerings by institutions covered in the Guide. In addition, we have specific mechanisms in place to facilitate internationalisation, and our immigration policies have been relaxed to make it easier for international students, academics and other higher education staff to enter the country and stay for the duration of their planned activity. We also subsidise students from the continent in terms of our policy on the state subsidisation of foreign students at higher education institutions. South Africa shares the global concern about the digital and information divide. We are of the view that access to information is empowering and would therefore like to see as many citizens of our country and the continent connected with the rest of the world, both digitally and in terms of knowledge. By staying in touch with the rest of the world through information sharing and exchange programmes, we minimise this information gap. It is for this reason, therefore, that the work of IEASA in the form of this publication is applauded, because it seeks to promote such exchanges and information sharing. There is no question that through internationalisation we can impact on our political, economic, cultural and social transformation. We can also address our skills shortage, build research capacity, enrich curricula and enhance the student experience. Collectively higher education institutions in South Africa offer an impressive array of information and communication technologies, well stocked and interconnected libraries and some scholars who are among the best in the world, making the country a destination of choice for both Africans and students from abroad. We aspire to make all our international partners, students and staff feel at home and content with what our institutions offer them, pleasant living and study or work environments. We want them to be proud of their association with South African higher education and be ambassadors for the system once they leave South Africa. , 7th Edition

- Description: [Extract from message from Minister of Higher Education, Hon. Naledi Pandor]: It gives me great pleasure to endorse the 7th edition of Study South Africa. The International Education Association of South Africa (IEASA) has once again produced a publication that provides valuable insights and information about South African public universities and their place in the global higher education arena I welcome this publication and congratulate IEASA for its hard work in promoting our higher education institutions internationally. Study South Africa gives a comprehensive picture of higher education in our country.

- Description: [Extract from message from Minister of Higher Education, Hon. Naledi Pandor]: It is a great pleasure for me to give a word of support to the sixth edition of Study South Africa: The Guide to South African Higher Education. I am particularly pleased with the effort and level of commitment shown by the International Education Association of South Africa (IEASA) in promoting South African higher education institutions internationally. The internationalisation of our higher education system is an acknowledgement that South African universities have a valuable contribution to make to the global higher education community, and in particular on the African continent. In this regard, I am pleased to note that of the 52,000 international students enrolled in our institutions, the majority come from the African continent. South Africa's higher education institutions offer unique benefits for international students, blending the experience of living in Africa with the opportunity to obtain internationally recognised qualifications at reasonably affordable costs. Also, high quality educational infrastructure, unique research opportunities, and a rich variety of cultures make South Africa one of the favourable study destinations for many international students. More than ever before our institutions are working hard to ensure that they provide high quality education, comparable to the best in the world. Our institutions continue to strive towards excellence and also to encourage international students, particularly those from Africa, upon completion of their studies to go back and make valuable contributions to the socio-economic development of their home countries. IEASA, Higher Education South Africa (HESA) and our universities have played a valuable role in reinforcing South Africa's international relations in academic and research exchange programmes. The Ministry would like to take this opportunity to commend IEASA and HESA for the dedicated efforts and targeted interventions made towards achieving our national priorities. , 6th Edition

Understanding educator-mediated conflict resolution in a preschool environment: the experiences and feelings of preschool educators

- Description: This thesis discusses the experiences and feelings of preschool educators when resolving situations of conflict between preschool children. Data was collected by means of semistructured individual interviews with preschool educators and a video recorder recording conflict situations among preschool children focusing on educator resolution strategies. Grounded theory was used as a data analysis technique to analyse the data collected. The analysis revealed that the preschool educators under study do not use mediation as a conflict resolution strategy but use various strategies that include, prevention, directive approach, arbitration, myths and threats and rules. Data analysis also revealed that these preschool educators encounter experiences and feelings before, while and after intervening in the conflict situations of children. These findings imply that preschool educators lack the professional skill of conflict resolution. This suggests an urgent need of restructuring of the preschool educator’s training to include conflict resolution training as one of their important component. Educators and parents also need to be consulted or involved in the process of restructuring the training.

An analysis of the compliance approach used by revenue authorities with specific reference to case selection and risk profiling

- Description: The vision of probably all revenue authorities is to promote compliance with the provisions of the taxation laws and to ensure responsible enforcement by the revenue authorities, thereby contributing to the economic well being of the country. As with virtually all revenue authorities the South African Revenue Services has to a large extent implemented the self-assessment approach to tax assessments. Because this system depends on this process of selfassessment, an effective risk-based audit approach is required to ensure that tax compliance and responsible enforcement is adhered to. An effective case selection methodology is required for revenue authorities to make informed choices on how best to direct their activities in order to address areas of greatest risk. Given these imperatives, the purpose of this study is to examine the case selection methodologies used by certain revenue authorities, including the South African Revenue Services, and to focus on the key elements of case selection: the use of computerised database systems, industry profiles, third party data and the role of the risk profiler. The results of the study indicate that the case selection methodology of the South African Revenue Services is lacking in some areas. Computerised risk analysis is limited to a certain classes of taxpayers and other aspects of concern are also highlighted in this study.

Participation and dialogue in development

- Description: "Participation" is a frequently articulated requirement within the context of community development. Yet despite this, the concept of participation is neither comprehensively theorised, nor entirely unproblematic. The theoretical paucity surrounding participation is particularly marked within accounts of its interactional and relational dynamics . This thesis is accordingly concerned with theorising the interactional and relational features of participation in, and for, development. To this end a small development intervention, constituted as an agricultural co-operative within a rural area of South Africa, is examined. In this inquiry the phenomenon of participation is viewed through the lens of dialogical-activity. This enables explication of the "joint activity" directed towards participatory development, within the focal research setting. The overarching theoretical framework for this thesis is conferred by Activity theory. Orientated towards examining the collective and artefactually mediated nature of human action, Activity theory is foregrounded in Y. Engeström's (1989; 1999b) analytic schema of the Activity System. This Activity System framework is expanded by the inclusion of communicative and semiotic elements; an inclusion effected by reference to R. Engeström's theory of communicative action (1995,1999), which in turn, draws on theoretical precepts gleaned from the work of Mikhail Bakhtin. The resultant fusing of dialogue and activity therefore serves to extend Activity theoretical insights. The results of this research are based on data collected from a multitude of sources within the focal participatory development research setting, including internal project documentation, interview transcripts and field notes. The dialogical Bakhtin-derived an alytic categories of speech genre , voice and social language were drawn on in order to examine this textual data , and to explicate the interactional and relational features of participatory development. Analysis of these served to reveal the polyphony of (speech genre constituted) voices, wherein the phenomenon of participation is disparately accentuated. The results chapter moreover discusses the substantial mismatches and discontinuities in the referential object invoked by the various roleplayers, within the focal research context. This thesis considers the sources of these discontinuities and tensions, including how they point to historically constituted contradictions within participatory development. It furthermore briefly examines the opportunities and affordances these offer up for expansive new forms of activity. Finally, in re-examining participation and development, the complex, and sometimes antithetic relationship that exists between these two concepts and their associated social practices, are considered.
