M.Tech. (Architecture) / This research interest stems from observing at close range (and researching historically) a seemingly impermeable cycle of occupation, violence and abandonment within the inner-city, whose roots stretch back over the past 130 years 1. The cycle has culminated in the 'writing off' of a number of inner-city buildings as 'bad buildings' not fit for habitation or study. This dissertation is both an architectural response and a research inquiry into how design, in its broadest sense, might contribute to an inner city 'vertical settlement' ...

M.Tech. (Architecture) / To heal- to make whole (Heal 2014: [sp]). The journey to good mental health is a multi-faceted one, and one which involves more than solely medical or institutionalised notions of treatment. This research proposal explores a phenomenological approach to understanding space, recognising that our embodied experiences of our environment can inspire, balance and heal the human spirit, to the same degree that can oppress and harm it ...

Integrative Summary: Municipalities are the third level of government and are responsible for delivery of basic services to citizens. They carry the developmental mandate of government and are often the first point of interaction between government and citizens. Being at the front line of service delivery, the issue of fiscal stability of municipalities and their ability to deliver sustainable services is of grave importance (Carter & Ajam 2003). Unfortunately in a South African context most municipalities are not fiscally sustainable (Roos & Stander 2005). In a study of 142 South African municipalities, it was found that poor collection of outstanding debt and irregular or wasteful expenditure were the biggest causes of fiscal stress (Roos & Stander 2005). In fact, in 2004 the difficulties appear to have reached crisis level (Lubbe & Roussouw 2005). The fiscal situation within municipalities was so bad that the South African Local Government Authority (SALGA) implemented a unit specifically to assist municipalities that were at “crisis point” (Roos & Stander, 2005 p. 165). This research report focuses on the evaluation of Igoli 2002 which was a response to fiscal crisis within the City of Johannesburg metropolitan municipality when in 1997 the City of Johannesburg was declared insolvent. The research evaluated the long term sustainability of the Igoli 2002 programme to determine its success in addressing the issues of fiscal stress and crisis facing the municipality. The research also attempted to assess the applicability of international indicators of fiscal stress and crisis to the City of Johannesburg. The research evaluated the Igoli 2002 programme via a financial condition analysis, against international indicators of fiscal stress and crisis and against a logic framework detailing the goals of the programme. The research found that ultimately, the Igoli 2002 intervention implemented by the City of Johannesburg was successful in improving the fiscal position and sustainability of the City. In addition, indicators from predictive models of fiscal stress and crisis were found to be relevant to the City of Johannesburg.

Saving clubs or stokvels have been around in many parts of the World, under different names, for many years and they have been instrumental in teaching people how to save. This research sets to investigate the possible use of stokvels as vehicles, channels or conduits for wealth accumulation among migrant population living in the inner city of Johannesburg. Participants’ contributions and the extent this translates into wealth accumulation among members were critically examined. Furthermore, the study explored whether gender plays any role in terms of stokvels membership and the reasons thereof. The hypothesis of this research was that incomes from stokvels contribute to wealth accumulation of migrants in the inner city of Johannesburg. This study used both quantitative and qualitative research methods to address the research questions and gather relevant data. The use of a mixed approach was adopted as it allows a deeper exploration of the different research objectives and questions of the study. Thematic content analysis was used to analyse the data. The findings of this study have revealed that there is a positive relationship between membership to stokvels and wealth accumulation. Moreover, trust and social capital were found to be pivotal in ensuring success of these groups in terms of who should be accepted into the group. However, many other factors, such as the level of education, the length of stay in South Africa and the marital status of participants could have an impact on wealth status of participants.

M.Phil. (Energy Studies) / In recent years, the costs of electricity in South Africa have increased enormously, thus, most institutions of higher education are seeking ways to manage their utility costs by reducing consumption rates. Hampering their initiatives, however, is the fact that South Africa in general, and buildings in particular, lag the world in knowledge and implementation of demand side management strategies. This case study outlines the efforts of a large metropolitan university in Gauteng to examine the implementation of energy efficiency within the context of the green or sustainable campus movement. The study comprises three core parts: analysis of electricity consumption data; identification of institutional barriers inhibiting implementation of energy efficiency projects, and, lastly establishing key role players responsible for effective implementation. The study found that seasonality and the campus academic calendar both have profound effects on energy consumption. High demand coincides with winter and a distinct correlation was found between peak consumption and core working hours. Consumption peaked at an average of 2 500 kWh during active ‘in-session’ periods. Less active, ‘out-of-session periods’ recorded an average peak of 2 250 kWh. The lowest average peak consumption of 2 100 kWh occurred during ‘recess’ periods. Similar patterns were evident for the maximum demand. It was evident that the university had a high base load (between 1 300 kWh and 1 650 kWh). This high base load could be attributed mainly to the heating and cooling system. To stimulate decision making towards improved options, an energy savings financial model was developed to provide a tool for calculating the return on investment period for energy efficiency projects. Interviews conducted with key role players (in the university’s operations, academic and management divisions) and a staff questionnaire were used to establish the main barriers to energy efficiency implementation: a) the absence of an energy policy; b) a general low level of awareness of institutional energy efficiency activities and (c) the shortage of dedicated, skilled staff to implement energy efficiency projects. The managerial, operational, and financial divisions are arguably the key role players in energy efficiency projects. Lastly, leadership commitment from the highest levels of the university is required. The novel contribution of this thesis is through combining technological and behavioural approaches to energy efficiency at a tertiary institution through a mixed method study design. Key recommendations are presented to stimulate energy efficiency implementation.

Introduction Run-off from Johannesburg mine dumps is a source of environmental pollution and a public health concern. This study focussed on assessing and developing remediation strategies for Manuel Street Park (MSP) that has been affected by run-off from the Princess Mine dump. Study objectives were threefold: to use a survey involving residents living around MSP to determine community use and perception of rehabilitation of the Park; to determine the impact of the addition of a preparation known as “Effective Micro-organisms” (EM®) to polluted Park soil and; to prepare a remediation plan for this Park. Methodology A qualitative survey was conducted amongst users of the park as to their use and perceptions of rehabilitation of the park and their understanding of mine-related pollution and acid mine drainage. Controlled greenhouse trials were conducted to determine optimal germination and growth of Pennisetum clandestinum (Kikuyu grass) in Park soil, with and without EM® or compost. A landscaper was consulted to collate research results to facilitate park rehabilitation. Results Survey participants understood the risks of Acid Mine Drainage (AMD) and other mine pollution and gave valuable information which assisted in understanding local issues concerning the park. Tests with soil polluted with AMD showed that it promoted seed germination while treatment of park soil with fertiliser, compost and enhanced microorganisms improved plant development and growth. Practically, it was determined that the use of EM1 at the park would be difficult because of on-going flooding of the park with contaminated water. For this reason, an improved drainage plan was suggested, along with raised walkways. Conclusion A remediation plan can be implemented on site involving installation of French drains, raised walkways, and soil remediation involving EM® / Agriculture, Animal Health and Human Ecology / M.

M.Tech. (Architectural Technology) / A persons' well-being is characterized as health, happiness, prosperity and as being in a good state of existence. The way in which we maintain our body, by eating the correct foods to exercising on a daily basis, is an important part of maintaining our well-being. Medical authorities regard South Africa a shaving one of the healthiest environments and climates in the world. South Africans get to enjoy sport and outdoor activities, fresh fruit and vegetable sand some of the planets cleanest air (Health issues in South Africa 2011: [sp]). This however is not the case for many South Africans living in poor overcrowded conditions with the lack of basic facilities. Within the medical field are large areas of controversy, particularly with HIV/ AIDS treatments between Traditional medicine and Bio-medicine. The dissertation will not focus on the study of one specific ailment and space related to health care. Instead an attempt is made to create a space where a multitude of medical functions can operate and share space in a symbiotic relationship. This would ultimately create a place of well-being and healing, where public health can be re-invent for a broader audience through mixed use facilities, social interaction and nature. The investigation area of the dissertation takes place in Yeoville and the function of the building will examine the notion of a Mixed Use Healthcare Centre. The architecture will look at the human scale and needs whilst Nature will deal with form and function. The Design intervention attempts to dissect the existing healthcare system and inject new and fresh responses to the ailing problems in the industry. There are currently large gaps in the public and private sectors of South Africa as well as the dialog between Traditional medicine and Bio-medical practices (Richter 2003: [sp]). The concept of the intervention is to provide a closed loop Healthcare system where the project becomes self sustaining within the Social conditions, Function of space and the Well-being of people This will be done by investigating the existing typologies of healthcare systems in South Africa and by combining both Traditional Medicine and Bio-Medicine. This could allow a better communication network to establish between the two disciplines and provide more information about heath and well being to the public. The intervention can become a framework for future health care establishments where a multitude of functions can operate under one roof providing affordable treatment and advice to...

A dissertation submitted to the School of Language, Literature and Media, Faculty of Humanities for the degree of Doctor of Philosophy, March 2017 / Although the burgeoning fields of linguistic and semiotic landscapes (LL and SL) studies provide extensive coverage of urban settings around the globe, it lacks a focus on urban development and the associated phenomenons such as gentrification, with the notable exception of Lou (2016). This dissertation looks at the neighbourhood of Marshalltown, located in the inner city of Johannesburg. Marshalltown is known as the mining district because of its proximity to the original goldmines that sparked the growth of the city. The neighbourhood’s SL has radically shifted from a place of urban decay to a trendy neighbourhood since the late 1990s, after urban development efforts financed by the private sector made the area stand out from the rest of the inner city. The developers working in Marshalltown have purposefully filled it with signs indexing the mining heritage its businesses which tend to cater to the middle-to-upper-classes, thus excluding poorer residents which make up most of the inner city’s population. Against this backdrop, the dissertation aims to answer the following three research questions: 1) How is Marshalltown constructed as a space of heritage, both in its materiality and in its representation in a corpus of media texts? 2) Considering that heritage entails a selection process from a more general historic field, which sections of history are curated in Marshalltown’s SL, which are silenced, and what are the implications for the narratives displayed in the context of post-apartheid South Africa? 3) How is Marshalltown’s urban environment experienced by social actors in a context of globalized trends in urban design which rely on heritage and authenticity to market formerly ignored city centres? The data for this study consists of a corpus of 25 media articles from various outlets, 255 photographs of Marshalltown and its vicinity, ethnographic field notes written between 2012 and 2016, as well as interviews with developers, heritage architect, a deputy director of immovable heritage at the City of Johannesburg, shop owners and people who work in the area. This dissertation aims to contribute to the young field of SL studies, while bringing forth Scollon and Scollon’s (2003) methodological toolkit of geosemiotic which allows for an analysis of signs in place and how people interact with them to draw a pertinent analysis of the construction of place. Geosemiotics is coupled with specific themes for each analytical chapter which brings forth a new way of analysing a SL. Those themes are 1) the language of urban development which drawing on Markus and Cameron (2002) helps analyse the representation of city neighbourhoods; 2) heritage, which brings a temporal perspective to SL studies that I call a chronoscape; 3) authenticity, which brings a visual analysis addition to the recent debate on the topic within sociolinguistics scholarship (Coupland 2003, Bucholtz 2003 and Eckert 2003) and its focus on the discursive construction of what counts as authentic. This study argues that Marshalltown’s post-apartheid SL is carefully designed by a majority of (white) developers wanting to give the area a heritage feel, borrowing from the mining history of the city; thus anchoring a European influenced heritage within their own interpretation of what an African city should look like. The heritage feel of Marshalltown is part of a broader plan to reclaim the city, which means changing the image it acquired previously during an era of urban decay as a dangerous no-go area, into an attractive tourism-friendly urban space. Those changes are achieved by inserting development efforts into the market for authentic urban lifestyle which Marshalltown can provide thanks to its preserved history. The neighbourhood stands out from the rest of the inner city by being privately controlled and maintained thus distancing itself from the popular discourse of inner city Johannesburg and instead developers redesign it as an ideal space for consumption. / XL2018
