[pt] Este trabalho analisa se a eleição de mineradores como prefeitos em municípios brasileiros tem implicações sobre o gasto público ambiental e a saúde pública. Primeiro, ao combinar diferentes bases de dados públicas administrativas, este trabalho identifica candidatos a prefeitos que detém uma licença de mineração. Então, eu seleciono eleições com margem de vitória estreita para aplicar uma regressão com descontinuidade que estima os impactos de eleger um prefeito minerador na despesa pública ambiental. Na sequência, utilizando diferenças-em-diferenças, eu foco na eleição de prefeitos mineradores de ouro, cuja extração artesanal é altamente tóxica, e verifico se a potencial emissão de mercúrio pelos garimpos afeta a saúde pública em municípios vizinhos. Em ambos os casos, este trabalho não encontra um efeito causal estatisticamente significante, porém, a análise carece de poder estatístico por conta do tamanho reduzido da amostra. / [en] This paper analyses whether electing a miner as mayor in a Brazilian municipality has implications on municipal environmental expenditure and general health. First, by merging different public administrative data, this paper identifies candidates for municipal office in Brazil who hold a mining permit. Then, I use close elections to apply a regression discontinuity design to estimate the impact of electing a miner mayor on public environmental expense. Furthermore, by using a difference-in-differences approach, I focus on the election of mayors who mine gold, a highly contaminating activity, and check whether potential mercury contamination due to gold mining affects health outcomes in neighboring municipalities. In both cases, this paper does not find a statistically significant causal effect, however, the analysis lacks statistical power due to the small sample size.

Countries and governments around the world have accepted the scientific argument on the prevalence and the possible effect of global warming and climate change on the environment, world economy and ultimately human life (Nhamo, 2011). Amongst all industrial corporations, the mining industry is the biggest environmental polluter due to its extractive nature and energy intensive operations. However because of its economic importance, it cannot be abandoned, instead it needs to find a win-win situation, where it continues to succeed but minimizes environmental damage. This thesis aims to examine the possible impact of clean technology on the sustainability of South African gold mining sector. Specifically, the study aims to determine the drivers behind the move towards clean technologies and methods, identify challenges and opportunities associated with this transition at Harmony Gold’s Kusasalethu mine. This was achieved through using Kusasalethu as a case study to which investigations of the effectiveness of clean technology and methods were carried out. The case study was multidimensional; exploring the effect of clean technology on energy consumption, greenhouse gas emission (GHG), water consumption, cyanide management and Kusasalethu’s financial performance. While the case study was largely qualitative it involved quantitative data analysis that had to be triangulated with other data sources and data gathering instruments to achieve legitimacy. This meant that the study had to adopt the mixed research methods. The instruments used included; key informant interviews, and document analysis, structured questionnaire and a set of open ended questions that served as interview guide. The qualitative data were analyzed by means of coding, descriptions, typologies, taxonomies and visual representations, whilst quantitative data were processed through Microsoft Excel to generate various forms of descriptive statistics. The findings indicate that resource consumption (energy, water, cyanide) depends on the mine design and gold output rate. Clean technology implementation at Kusasalethu helped the mine reduce energy consumption and GHG emissions. However scope 2 (indirect GHG emissions associated with energy consumption) is also determined by coal production technologies and methods used by coal mines. Although data on Kusasalethu water and cyanide management and related technologies was not available, the aggregate data for all Harmony Gold mines indicated higher annual water and cyanide consumption during 2010 and 2012. In terms of Kusasalethu’s financial performance and clean technology adaptation, acquisition of clean technologies increased capital expenditure temporarily. However, the positive effects of the clean technology transition and implementation minimized operational cost and increased operational profit greatly. Although adopting clean technologies calls for increased capital expenditure, this study reveals that this expenditure pays off in lower operation costs for the mine and the environment benefits through lower GHG emission. However, clean technologies are yet to impact significantly in lowering water and cyanide consumption levels as they do with energy consumption. The study concluded that clean technology and methods played a positive role on Kusasalethu’s environmental impact and financial performance by reducing energy consumption and GHG emissions. Though, more need to be done in terms of water and cyanide management. / Environmental Sciences / M. Sc. (Environmental Management)

Memento Mori, Latin for “remember thy death,” implores us to be mindful that death is both inevitable and inescapable. What of the records created during the process of dying and about death? Based upon wide-ranging archival research into primary documents, this thesis explores the rich sources of both official, public records, and personal, private ones, relating to mortality on the small-town Canadian frontier before 1950. The community of Red Lake, Ontario, which was established on the frontier as the result of the Red Lake gold rush of 1926, is the subject of a case study. Rather than merely cataloguing sources, this thesis illustrates that by adapting aspects from such archival appraisal methodologies as macroappraisal and documentation strategy, one is able to make available to researchers a wider range of sources relevant to the themes of dying and death. Specifically, by employing a documentation strategy methodology to identify and illuminate the records of human activities surrounding the functions of dying and death, archivists can offer to researchers the opportunity to locate relevant records wherever they may physically be. Since this is an Archival Studies thesis, it does not provide an historical analysis of dying and death, but is an archival study of the types of records related to the theme of mortality on the Canadian frontier: how those records were created, their character, and their capture and preservation in a small community. This thesis is organized into three chapters and a conclusion. Chapter One explores some relevant trends in the secondary literature of three fields: archival appraisal and description, small town or local development on the frontier, and dying and death as human activities. Chapter Two sets the context in which the thesis analyzes mortality on the frontier by outlining the relevant history of the Red Lake District of Northwestern Ontario and its pioneers. The focus is especially on the gold-mining boom years from the mid-1920s until shortly after the Second World War. The heart of the thesis, Chapter Three, is a case study of the various records creators, human activities, and resultant records related to mortality. It is organized according to three phases or functional categories surrounding dying, death, and memorialization. The conclusion summarizes the usefulness of the case study, in light of the literature review in Chapter One. It also suggests areas of further research, including aspects not covered herein, of the records of dying and death on the Canadian frontier. The documentation strategy, adapted from the original methods employed by archivists Helen Samuels and Richard Cox, was found to work best when deployed as a research and descriptive tool for exploring and documenting the records of mortality, more so than its original purpose as an acquisition tool. The strategy has wide-ranging usefulness discovering and then describing a “virtual” documentation universe relating to record-generating human functions and activities. / February 2008

This paper examines the different share valuation methods and principles likely to be used by a court in determining the fair value of dissenting shareholders’ shares in appraisal proceedings in terms of section 164(14) of the Companies Act 2008. It is submitted that the valuation principles and methods used by the courts will affect the operation of the triggering actions contemplated in subsections 164(2)(a) - (b). It is proposed that section 164 court appraisals are likely to be guided by the valuation methods and principles developed in section 252 and section 440K court appraisals under the Companies Act 1973, as well as by the decisions of the courts in the state of Delaware relating to share valuations under the appraisal remedy. It is further proposed that the purpose ascribed to the appraisal remedy will influence the application of these valuation methods and principles. / Mercantile Law / LL.M. (Corporate law)
