Item 120 years of excellence in service to Mining.(The Southern African Institute of Mining and Metallurgy., 2017-04) Musingwini, C.The Wits School of Mining Engineering, which is celebrating 120 years of service to the mining industry, is the seed from which the University of the Witwatersrand grew, and is now the largest mining school in the English-speaking world.Item A picture speaks a thousnd words: understanding women's migration in Johannesburg using visual diaries(Routledge, 2010-09-23) Kihato, CarolineUsing the visual diaries of a group of African women migrants now living in Johannesburg, this article explores what is now termed "ferminization of migration". It does this less by drawing attention to the fact that women are moving than by using women's own images and narratives to reveal dimensions of that experience that have yet to be understood. Centralto the article's arguement is the assertion that images communicate to us in ways that can reveal not only the material conditions of groups that are often hidden from view, but also their own local political locations, and society's own assumptions about them. Women's visual diaries and their narrative reveal the ways in which they negotiate structural impendiments of asylum offialdom, police harassment, patriarchy, unemployment and poverty. The research argues that current understanding of the ferminization of migration fail to reveal the socio-cultural and political complexities of women's mobility on the African continent.Item Abramowitch, Punshow & Schneider Architects.

The collection of papers documents low-income residents’ everyday relationships with the state, through the study of actual practices of interaction with a range of state representatives at the local level (councilors and officials, at various levels of local government). Formal and informal, legal and illegal, confrontational and cooperative, we analyze the multiple tactics of engagement with the state by low-income residents to understand the extent to which they allow access to state resources and to degrees of state recognition, even in contexts of mass poverty, informality and scarce public resources. The modes of interaction with the state also embody and frame low-income residents’ representations of the state, of their expectations, and of their own citizenship. This special issue thus critically draws together a wide-ranging and important debate on governance, and the relationships it constructs between state and civil society. The main question we thus raise in this special issue is how the dynamics of governance reform, with attempted development or deepening of both decentralization and participation, affect everyday practices to access the state and the resulting politics that shape state-society relations in southern contexts. Collectively, the articles in the special issue reflect on the ways in which low-income citizens access to the state challenges existing theories of the state and democracy. Stemming from a research programme entitled ‘The Voices of the Poor in Urban Governance: Participation, Mobilisation and Politics in South African Cities’, this special issue focuses on South African cities primarily but not exclusively. Although the contexts examined have their own specificities, we argue that they provide an interesting and critical context in which to work through the debate from a Southern perspective. South African societies are specific in the huge expectations residents have in the post-apartheid state, and in the ways that ideals continue to be framed in modernist terms, as emblematized by policies of mass public housing delivery and effort towards mass access to urban services. The state, even if it is not so powerful, remains at the core of representations and expectations especially of lower income residents (Borges 2006) – mass urban protests which continue to rise in South African cities today show the disappointment of these expectations rather than a disregard, ignorance or avoidance of the State (Bénit-Gbaffou 2008, Alexander 2010). Attempts to address the gaps between expectation and public delivery have taken the form of major local government restructuring in a post-apartheid context, relying extensively on principles of good governance (decentralization, democratization as well as new public management principles). However, these expectations and experiences of confrontation of civil society with the state co-exist with everyday practices of negotiation, seeking of favours, and clientelism, which also shape residents’ access to resources, and more broadly their representations of the state and the construction of their urban citizenship (Oldfield and Stokke 2004). The South African case is thus particularly relevant to study the interaction between the modern state and good governance ideals, and practices of ‘political society’.Item Acid mine drainage and its governance in the Gauteng City-Region(2015-05) Bobbins, KerryAcid mine drainage (AMD) in the Gauteng City-Region (GCR) has been described in the media as a ticking time bomb after it was officially reported to have begun surfacing from old mining works on the West Rand in 2002 (Masondo et al., 2011; TAU SA, 2011; Slack, 2013). Acid mine drainage occurs when ‘fool’s gold’ (FeS2) or iron pyrite found in mined rock oxidises. This occurs when either underground mine shafts, or crushed conglomerate in Mine Residue Areas (MRAs) on the surface, become exposed to oxygen and water creating run-off that is very high in sulphates – effectively sulphuric acid – and is hazardous to both humans and the environment (McCarthy 2010). Over the last decade, a flurry of news articles have highlighted the threat of acid water decant and its likely effects on human health, the environment, water quality, municipal infrastructure and building foundations in the Johannesburg Central Business District (CBD). These reports have fuelled anxieties around when and where decant will take place and who will be affected by AMD. In response to these concerns, government, through the National Department of Water Affairs (DWA), has introduced a set of immediate and short-term interventions to overcome decant in the West Rand. These have allowed AMD to be framed as an environmental emergency. DWA has also set in motion a process to develop a long-term solution that, through a broader and more inclusive approach, will solve various AMD issues over time including its impact on the Gauteng water supply. In relation to both these two government interventions – the immediate/short and long-term solutions – very few stakeholders or members of the public know enough about AMD and its governance to understand what the real challenges are and how they should respond. Even fewer are able to piece together the series of events that led up to the current and proposed set of actions taken by DWA to tackle AMD. This paper argues that the current trajectory of government-led responses has suspended meaningful public engagement and debate, and the result is a grey cloud of misinterpreted facts and presumed motives that has cast a shadow of misunderstanding, which in turn exacerbates the anxieties of affected communities and interested stakeholder groupsItem Advancing international collaboration through the Global Mineral Professionals Alliance (GMPA).(The Southern African Institute of Mining and Metallurgy., 2017-03) Musingwini, C.Extract from Editorial: The GMPA is currently composed of six sister institutes: the Australasian Institute of Mining and Metallurgy (AusIMM), the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), the Institute of Materials, Mining and Metallurgy (IOM3), the SAIMM, the Society for Mining, Metallurgy and Exploration Inc. (SME), and the Instituto de Ingenieros de Minas del Peru (IIMP).Item Adventures in City Data: An Ethnographic Story(Gauteng City-Region Observatory, 2022-12) Shirley RobinsonSouth Africa is urbanising rapidly, and its economic landscape is continuously changing as a consequence. In this context, city governments and urban scientists have long called for better access to city economic data. The National Treasury has reinforced this demand, insisting that intra-city economic data is critical in order to improve planning, performance and investment in South Africa’s cities. A wealth of data is collected by the South African Revenue Service (SARS) in the course of its routine operations assessing the tax obligations of companies and individual taxpayers. In addition to its bureaucratic purpose, this data represents an enormous potential resource for a detailed understanding of the urban economy. Until recently, this resource has been underutilised because it was not available in an anonymised and geocoded form. At a practical level, however, the significant amount of energy and time required to access, clean and align administrative datasets to make them usable is not generally understood. This GCRO Occasional Paper presents an ethnographic account of a decade-long journey in city economic data collation by the author who, as a long-term technical advisor to the National Treasury’s Government Technical Advisory Centre (GTAC), led the work on the city economic data programme in support of the first phase of the National Treasury’s Cities Support Programme (CSP). After observing the critical need for anonymised and geocoded economic administrative data in policy formulation and urban research, this paper examines the reasons for the limited availability of datasets able to show the location of economic activity and employment at a disaggregated local level. The paper details how the National Treasury’s collaboration with the World Bank in 2016 to produce the Urbanisation Review of South Africa stimulated and directed the efforts of GTAC and the Economies of Regions Learning Network (ERLN) to pursue official sources of city-level administrative data. The paper goes on to recount subsequent National Treasury/CSP collaborations with Statistics South Africa, SARS and the Unemployment Insurance Fund (UIF) to collect and collate anonymised and geocoded city economic data from sources other than national general surveys. Despite progress, these efforts were ultimately stymied due to practical and governance constraints. Nevertheless, in a parallel process, these collaborations ultimately bore fruit in the establishment of a secure administrative data centre at the National Treasury that stores anonymised data, which can then be geocoded using postal codes. This secure data centre in turn, after the author had left the process, ultimately provided a foundation for the milestone publication of the 2021 City Spatial Economic Data Reports. The paper concludes by reflecting on the insights from this ethnographic account around possibilities for improving the integrity of the city spatial economic data resource, and enhancing its use in credible, evidence-based urban analysis. First, these conclusions highlight broader institutional and public management concerns in the current governance environment on which future steps to improve the city spatial economic data will depend. Second, the paper points out that, despite the long journey travelled, business classification uncertainty still remains. Solving these governance and data puzzles may further enhance the incredible potential that such a rich data resource holds for evidence-based policy aimed at creating a more just and equal society in South Africa.Item African Architect; a Journal devoted to the interests of the Architectural Profession in South Africa(Institutes of South African Architects and the Chapter of South African Quantity Surveyors, 1914)African Architect; a Journal devoted to the interests of the Architectural Profession in South AfricaItem African Architect; the Journal of the Association of Transvaal Architects(Institutes of South African Architects and the Chapter of South African Quantity Surveyors, 1912)African Architect; the Journal of the Association of Transvaal ArchitectsItem African Architect; the Journal of the Association of Transvaal Architects(Institutes of South African Architects and the Chapter of South African Quantity Surveyors, 1911)African Architect; the Journal of the Association of Transvaal ArchitectsItem African Architect; the Journal of the Association of Transvaal Architects(Institutes of South African Architects and the Chapter of South African Quantity Surveyors, 1913)African Architect; the Journal of the Association of Transvaal ArchitectsItem Aiton Court: Relocating Conservation between Poverty and Modern Idealism(International committee for documentation and conservation of buildings, sites and neighbourhoods of the modern movement, 2013-01) le Roux, Hannah; Hart, Brendan; Mayat, YasminAiton Court, in Johannesburg, is a case study in how heritage and economics clash in economically constrained cities. This iconic and formally innovative Modern apartment block from 1937 is located in an area where the income levels of tenants are now very low. Although the building is protected by legislation, the viability of its restoration is being further tested by a rent boycott. The article covers the building’s history, and questions how to approach its conservation differently, given the strong demand for housing at a cost level that would be excluded by purely market–led gentrification. We propose that locating conservation strategies in relation to the building’s history and to other subsidies aimed at the public good may provide other routes to preserving Aiton Court.Item Alterations to existing House(ELLE, 2009) Le Roux, HannahThis tiny project added a small, largely indeterminate space to my house. It faces the garden and resolves the difficulty of a house with an existing kitchen on the north. The L shaped sliding doors and windows can be opened in different configurations, and along with the mobile, folding table, allow for winter/summer, indoor/outdoor, public/private variations of eating or just working in this stoep.Item An evaluation of the applicability of the extended situational leadership model to lower level management in the South African construction industry(University of the Witwatersrand, 1990-08-10) Cocotos, GeorgeThe vast majority of theories and models that have been developed around the concept of leadership have been conceptualized, and tested in the USA and other countries outside South Africa as discussed in the literature survey, Chapter 2 of this dissertation). Furthermore, the models developed have largely been theoretical models aimed to help leaders only to identify the most appropriate leadership style to use. None have however attempted to develop a model that leaders can use to implement the most appropriate leadership style once it has been chosen. Consequently, A D Jaff, using the most integrated and recently developed Situational Leadership Theory and Mode 1 of Hersey and Blanchard as a data base, developed the first leadership implementation model - The Extended Situational Leadership Model. Since AD Jaff's implementation model is a combination of various other leadership mode ls and theories, in order to fully understand the development of the Extended SL Model, all the relevant models are researched in this dissertation (see Chapter 2). This dissertation attempts to test the applicability of the Extended SL Model in a practical construction environment in South Africa. It further attempts to make adaptations to the model where relevant, after testing its performance value through the administration of 3 questionnaires to a sample of potential/practising black leaders (on-site construction managers). (This lS surveyed in Chapters 3 to 6 of this dissertation). The objective of this dissertation is therefore to attempt to test, and where necessary, to adapt AD Jaff's Extended SL Model so that : 1) this theoretical model may be implemented practically in a South African construction working environment (i.e. to prove that the mode 1 does work in practice) ( see Chapter 4). and to test whether 2) the adapted mode 1 is applicable for the training of future black Low-Level leaders in the South African construction environment. The adapted form of the model will, I believe, prove to be a useful tool for the training of black leaders within the South African construction organisations, where the volatile industry and changing economic and political environment of South Africa with ensure the emergence of black South African Low Level leaders in the construction industry in the near future.Item Analysis of Bounded Distance Decoding for Reed Solomon Codes.(South African Institute of Electrical Engineers., 2018-09) Babalola, O.P.; Versfeld, D.J.J.Bounded distance decoding of Reed-Solomon codes involves finding a unique codeword if there is at least one codeword within the given distance. A corrupted message having errors that is less than or equal to half the minimum distance corresponds to a unique codeword and therefore, the probability of decoding error is one for a minimum distance decoder. However, increasing the decoding radius to be slightly higher than half of the minimum distance may result in multiple codewords within the Hamming sphere. In this study, we computed the probability of having unique codewords for (7, k) RS codes when the decoding radius is increased from the error correcting capability t to t+1. Simulation results show a significant effect of the code rates on the probability of having unique codewords. It also shows that the probability of having unique codeword for low rate codes is close to one.
