M.Sc. (Aquatic Health) / Urban impoundments play both a recreational and functional role in the urban areas. From the recreational point of view these impoundments offer aesthetically pleasing environs as well as habitat for aquatic organisms in a built environment. The functional role of impoundments is related to attenuation of storm water run-off that is released into urban water courses. Storm water run-off can have adverse effects on the ecological integrity of aquatic ecosystems. Water quality will influence other physical and biological components of these systems. It is for this reason that the ecological health of impoundments is assessed from an ecotoxicological perspective, focusing on Westdene and Emmarentia dams in Johannesburg. It has become common practice to use aquatic biota to assess the impacts of human activities on aquatic ecosystems. This is because animals and plants can provide a long-term integrated reflection of water quality, quantity, habitat quality and other environmental conditions. Water and sediment quality were assessed by applying standard techniques and protocols. Fish were utilized as bioindicator organisms in order to quantify the concentrations of metals available in the dam. Abundance of the macro invertebrate community was also measured. Physico-chemical water analyses were done during each sampling period to assess the water quality against the South African Water Quality Guidelines. Ammonia, which can be toxic to aquatic life, remained high in both dams. High phosphate concentration during the low rainfall season in Westdene Dam could result in eutrophication related problems. The microbiological analysis of the water suggests that the main cause of faecal and total coliforms contamination of the impoundments possibly originates from dominant birds, African Sacred Ibis (Threskiornis v aethiopicus) and Egyptian Goose (Alopochen aegyptiaca ) in the dam and others water birds frequenting the dams. Abnormally high concentrations of the heavy metals Nickel and Chromium were found in the water body and fish (Clarias gariepinus and Tilapia sparmanii ) thus indicating bioavailabity of these metals resulting in bioaccumulation in fish. High concentration of Lead in sediment was recorded and may greatly impact benthic macroinvertebrates population and their habitat.

M.Ed. / Afknouery (bullying) is ’n wêreldwye verskynsel en die gevolge raak die afknouer, sy slagoffer en die hele gemeenskap. Hierdie navorsingstudie toon dat afknouery ’n werklikheid en ’n algemene verskynsel ook in óns skole is. Die insette van die skoolhoofde en leerlinge van die Verre Noord Laerskole, van Johannesburg-Oos D9, is gebruik om die omvang van afknouery in hierdie skole te bepaal asook die effektiwiteit van bestaande voorkomende maatreëls. Daar is gefokus op die verskillende vorms van afknouery, die oorsake en gevolge daarvan, die omvang van die probleem en die karaktereienskappe van “bullebakke”en hulle slagoffers. Skole se gedragskodes is onder die soeklig geplaas en voorkomende maatreëls en maniere van ingryping is bespreek. ’n Kwalitatiewe navorsingsmetode is gevolg om ’n diepgaande insig te kry in die skoolhoofde en leerders se menings en ervarings aangaande bogenoemde aspekte. Fokusgroep onderhoude is gebruik om inligting te bekom en die volgende kategorieë is geidentifiseer: • Die omvang van afknouery • Die formulering en implementering van ’n beleid teen afknouery • Strategiese ingrypingsaksie Die bevindings van die navorsing het aan die lig gebring dat die omvang van afknouery in Johannesburg-Oos D9, Verre Noord Laerskole, ernstige afmetings aanneem. Beleidsformulering teen afknouery en die implementering van sulke maatreëls is gebrekkig en te min ondersteuning bestaan vir die ontwikkeling van sodanige maatreëls en/of strategiese ingrypingsprogramme om die probleem aan te spreek. Daar word dus aanbeveel dat hierdie saak dringend en ernstig aandag ontvang en dat skole betrokke raak by voorkomende beleidsvorming en ingrypaksies. Die bekamping van hierdie euwel het ’n noodsaaklikheid geword wat nie langer verontagsaam durf word nie. Om die bestaan van afknouery te ignoreer, is om dit goed te keur!

Purpose – The purpose of this case study research was to develop a theoretical model of integrated reporting for Johannesburg Stock Exchange (JSE) listed companies. Design/Methodology/Approach – The goal of this case study research was to understand how and why integrated reports are prepared, to develop a theoretical model of integrated reporting for JSE listed companies through literature review and analysis of published integrated reports. In addition, to investigate the perceived success of integrated reporting by examining its requirements, objectives, enforceability and implications to the listed companies. Based on the above, to determine how companies fulfil the requirements of integrated reporting and what those requirements are. To determine by comparing published integrated reports of companies, similarities or comparability of the information published on integrated reports ascertaining the measurability of the success of the application of integrated reporting. Practical implications – This case study research provides a useful insight into drivers of integrated reporting. Limitations to the study – The lack of responses from industry experts contacted for interviews considered a limitation in validating the outcome of the study. Originality/Value – This case study research looks at the current adoption and application of integrated reporting by JSE listed companies.

M.Tech. (Fine Art) / The focus of this research is an exploration of aspects of liminality and how it manifests in selected unsanctioned public art interventions in ‘urban places’, specifically, the Johannesburg Central Business District. Liminality informs my own art work and to contextualise my practice I investigate Steven Cohen’s performance/intervention entitled Chandelier (2001-2002), and Alison Kearney’s The Portable Hawkers Museum (2003). I argue that unsanctioned public art maintains a liminal identity, a fluidity of ‘repurposing a space’ that is in constant shift between different dimensions of liminality. Such works create a zone between physical and conceptual space, challenging the relationships between people and places, the artist and the audience. Liminal spaces (such as the underside of bridges for example) provide the platform for new mediation to happen outside of the normal social structures. Homi Bhabha (1994:54) refers to this as a “third space” where transformation may occur, and it is this transformation of space and experience that I aim to explore in my work. In my practical component I present a body of unsanctioned public art interventions consisting of ceramic sculptures placed in urban liminal spaces in Johannesburg. I populate the chosen spaces with imaginative objects that playfully reflect my own cultural hybridity, and resultant liminal existence, in a post-colonial urban society. My practical work thus draws on analyses of the liminal aspects of Cohen and Kearney’s works as well as on aspects of my hybrid existence arising from my status as an immigrant in Johannesburg. Through my art works I attempt to engage with the local inhabitants without the restrictions of institutionalised arenas, allowing for a new experience of both the space and the artwork. Finally I record my own interventions in detail and compile an annotated photographic catalogue to document the sculptures in situ and the ephemeral life span of these unsanctioned public art interventions.

M.Ed.(Educational management) / The extensive changes in South Africa since the first democratic elections in 1994 have impacted immensely on educational governance. The South African Schools Act (RSA, 1996a) has brought about a major reform in education administration by decentralizing school governance to local school communities. The Constitution and its Bill of Rights (RSA, 1996b) has also impacted significantly on all areas of school governance. School management has to take cognizance of the South African Schools Act and the Bill of Rights when developing and implementing all school policies. One of the policies that all schools must have is a disciplinary policy. Notwithstanding the requirement that every public school should have a disciplinary policy to ensure a disciplined teaching and learning environment, there is a perception amongst educators and other stakeholders such as parents that learner discipline at schools is emerging as a serious problem. This is causing many schools to become ineffective institutions of teaching and learning. The aim of this research study was to explore and describe the experiences of school managers and educators of learner discipline in the school and classroom environment, as well as to ascertain from them their perceptions of a zero - tolerance approach to managing learner discipline. This was undertaken in order to formulate principles and guidelines for school managers and educators to effectively implement a zero - tolerance management approach to learner discipline. A qualitative research design that was explorative, descriptive and contextual was employed. This paradigm was chosen because of the relative newness of the topic to be researched in the South African context. The researcher conducted focus group interviews in order to collect data. The data collected were analysed and interpreted from which various themes and categories were identified. Quotations from transcribed interviews were given to substantiate the themes and categories identified through analysis. A literature control was also undertaken whereby these themes and categories were compared further with the relevant literature and also discussed. Several categories could not be substantiated and thus reflects the unique contribution of this research study. The themes and categories that were identified by the researcher and the independent coder, and the literature reviewed, provided the basis for the proposed guidelines formulated by the researcher. The guidelines focused on two aspects, namely, principles on which a zero - tolerance management approach towards learner discipline should be based and, guidelines for educators to use in dealing with the problem of learner discipline in the classroom situation. Since this research study has been limited to the city of Johannesburg one of the recommendations made by the researcher is that further research should be undertaken on the efficacy of a zero - tolerance approach to managing learner discipline in South African schools. Future research studies on this phenomenon must be based more broadly with special emphasis on the experiences and perceptions of educators in the townships of South Africa. Also, this research study should ultimately form the basis for further quantitative research.

Mining has a lasting effect on our communities and urban environments and is especially visible in the City of Johannesburg. The industrial processes that formed the gold mine tailings sites and the natural processes that effect these sites create enchanting port industrial sites. The current remediation includes either unaccessible engineered solutions or a site is left derelict and unsafe. Exploring these processes on the project site, the study investigated how pattern making, derived form residual patterns, can inform the landscape for a recreation space. The combination of natural processes and proposed new processes to form the basis of a recreational landscape is explored. / Mini Dissertation ML(Prof)--University of Pretoria, 2018. / Architecture / ML(Prof) / Unrestricted

Submitted in fulfilment of the requirements for the degree of Doctor of Philosophy, University of the Witwatersrand, Johannesburg, / Between Union in 1910 and the start of World War Two, urban racial segregation in South African cities evolved through three distinct periods. Initially, the predominantly white cities were the target of colonial planning initiatives to reduce overcrowding and prevent the development of industrial slums. After World War One, the regulation of African urbanisation was the primacy focus of urban policy. The living standards of the urban workforce were to be improved and controlled by excluding unemployed African people, by forcing the majority of the urban African workforce into compound quarters, and by establishing limited accommodation for African families in town. The racial administration of urban poverty was entrenched in the 1930s when, faced with the persistent growth of slums.the state bolstered white welfare initiatives and imposed even tighter residential restrictions on blacks living in urban areas.
