De l’or et des putes : vie et mort d’un village de 'squatters' abitibien

Cette étude s’intéresse au village de squatters de Roc-d’Or, surnommé Putainville, qui apparaît en 1936 avant d’être détruit par le gouvernement provincial au milieu des années 1940. Notre but est de comprendre pourquoi cette agglomération, qui est érigée illégalement sur les terrains gouvernementaux et qui est réputée pour être un important foyer de déviance, est relativement tolérée pendant une décennie avant que les résidences soient détruites ou déménagées à Malartic. D’abord, nous expliquons pourquoi cette agglomération, sans reconnaissance légale et dans laquelle les résidents ne sont pas propriétaires des terrains sur lesquels leurs bâtiments sont érigés, apparaît en Abitibi-Témiscamingue au début des années 1930. Ensuite, nous nous intéressons à l’aspect physique et à la population de Roc-d’Or. Le taux de masculinité, la mobilité, la diversité d’emploi et l’origine ethnique des résidents sont analysés. De plus, nous nous penchons sur la mauvaise réputation de Putainville : autant le contrôle judiciaire que la présence du monde interlope sont étudiés. Finalement, comme les mœurs légères des résidents et l’influence du curé de Malartic sont souvent considérées comme étant à l’origine de la décision d’éliminer ce village, nous évaluons la pertinence de cette croyance et nous déterminons si d’autres motifs, notamment monétaire ou politique, sont aussi entrés en ligne de compte.

Royalties minerais e capacidade de gestão em governos locais: um estudo em municípios mineradores de Minas Gerais

O presente estudo tem por objetivo realizar um diagnóstico da capacidade de gestão pública local dos municípios dependentes da atividade de extração mineral em Minas Gerais, a fim de avaliar seu nível de qualificação, identificar limitações ao fortalecimento institucional da gestão e investigar como a gestão municipal tem evoluído a partir do recebimento dos recursos da Compensação Financeira pela Exploração de Recursos Minerais (CFEM). A variável “capacidade de gestão” foi operacionalizada a partir da metodologia “Government Performance Project” (GPP), que propõe cinco dimensões de análise, a saber: gestão financeira, gestão de capital, gestão de pessoas, gestão de tecnologia da informação e gestão por resultados. Busca-se responder às seguintes questões: nas cidades mineiras dependentes economicamente da atividade de extração mineral, o poder público municipal demonstra capacidade de gestão adequada no desempenho de sua função? O recebimento dos recursos extras tem propiciado a melhoria da qualidade de gestão municipal? Para o desenvolvimento do estudo, realizou-se um estudo de casos múltiplos, tendo sido selecionados três municípios mineiros dependentes há vários anos da atividade de extração mineral: Mariana, Catas Altas e São Gonçalo do Rio Abaixo. Foram realizadas entrevistas semiestruturadas com técnicos, secretários municipais, prefeitos e cidadãos, buscando investigar a capacidade de gestão do poder público local nessas cidades. Embora os três municípios apresentem características comuns, como dependência da atividade mineral, proximidade territorial, contexto econômico e níveis de arrecadação elevados, nota-se que tais municípios representam três realidades diferentes, com níveis de desenvolvimento distintos. Foi possível identificar que os municípios estudados, sobretudo Catas Altas e São Gonçalo do Rio Abaixo, adotam boas práticas na gestão municipal. O município de Mariana apresentou recentemente boas iniciativas de mudança na gestão, entretanto, as mudanças políticas têm impedido que estas sejam concretizadas. Além das dimensões de análise do GPP, foi possível identificar outros fatores relevantes para o fortalecimento institucional da gestão, tais como, planejamento, perfil do gestor e contexto político. Verificou-se ainda que os impactos da mineração não se restringem à cidade mineradora, mas também às cidades localizadas no entorno da mina.

Our Lives, Our Thoughts and Our Allegiance: New Immigrants and American Industry in 1914

Through comparative analysis of the immigrant labor forces at work in iron mining in northern Minnesota, coal mining in Illinois, and steel milling in the Calumet region of Chicago and Gary, this paper addresses the forms of social distance separating and marginalizing new immigrants from American society and trade unionism that existed in 1914, the year that marked the end point of mass immigration from Eastern and Southern Europe. The “new immigration” was a labor migration that congregated its subjects overwhelmingly in what were called "unskilled" or "semi-skilled" forms of labor. Skilled work was largely, with certain variations, the preserve of "American" or old immigrant workers. This labor gulf separating new immigrants and American workers was hardened by a spatial separateness. New immigrants often lived in what have been called industrial villages—the mining town or location, the factory neighborhood— striking in their isolation and insularity from mainstream society. This separateness and insularity became a major preoccupation for corporate managers, Progressive reformers, and for American trade unions as new immigrants began to engage in major labor struggles leading up to 1914. But among the three industries, only the union of coal miners, the United Mine Workers, enjoyed success in organizing the new immigrants. In the steel mills and the iron mines, the unions were either rooted out or failed to gain a foothold at all. The explanation for these differences is to be found in the different forms of industrial development among the industries studied.

Geology and Ore Deposits of the Butte-Highland Gold Mine.

The Butte-Highland mine is situated at the head of Basin Creek, in the Highland mining district, Silver Bow County, about 14 miles south of Butte. The tunnel portal and present surface plant are at an elevation of about 7350 feet above sea level, facing westward across the head of Basin Creek valley. The "ghost" mining town of Highland lies a mile to the east, near the forks of Fish Creek. Access to the mine is obtained at present from Beaudine's siding, 12 miles west. The property may also be reached, with difficulty, over poor roads from Limekiln hill, or from Moose Creek.

Associaçoes comunitárias do meio rural : Um estudo de caso no centro oeste de Minas Gerais

This paper examines the association in a rural mining town in Brazil. The results belong to a master dissertationin Rural Extension on membership organizations and public policies for rural areas aiming to identify the roles performed by membership organizations, the reasons that explained their formation and their relationship with policy making for rural areas in the case studied. It is a case study, for which interviews were conducted with representatives of the organizations in order to deepen into the issues related to their historical, the roles they play and how and whether they participate in development project proposals. The results revealed anup-down process of formation of rural organizations, being created as bargaining tools for achieving collective benefits, reproducing dependency relationships

The Geology and Mineralogy of the Independence Mining District

From 1888 until 1893 the district was a booming mining camp. Seven stamp mills were running and ore was be­ing mined from the Independence, King Solomon, Poorman, Golden, Hidden Treasure and Crown claims. The town of Independence, which was on the Boulder River at the fork of Basin Creek, boasted a population of 400 people.

Geology and Ore Deposits of the Clinton Mining District

This report includes the results of geological investigation of the Clinton Mining District and the Hidden Treasure Mine.The Clinton Mining District is an unorganized mining dis­trict situated in the Garnet Range two and one-half miles northeast of the town of Clinton, Montana, which is on the Northern Pacific Railway and the Chicago, Milwaukee, St. Paul, and Pacific Railroad seventeen miles east of the city of Missoula. The district is in the same range of mountains as the Gar­net Mining District and the drainage from the district covered is to the south into the Hell Gate or Clarks Fork of the Colum­bia River. The main stream is known as Trail creek, which runs in a southerly direction from the area studied.

Geochemistry Of Acid Mine Drainage From A Coal Mining Area And Processes Controlling Metal Attenuation In Stream Waters, Southern Brazil.

Acid drainage influence on the water and sediment quality was investigated in a coal mining area (southern Brazil). Mine drainage showed pH between 3.2 and 4.6 and elevated concentrations of sulfate, As and metals, of which, Fe, Mn and Zn exceeded the limits for the emission of effluents stated in the Brazilian legislation. Arsenic also exceeded the limit, but only slightly. Groundwater monitoring wells from active mines and tailings piles showed pH interval and chemical concentrations similar to those of mine drainage. However, the river and ground water samples of municipal public water supplies revealed a pH range from 7.2 to 7.5 and low chemical concentrations, although Cd concentration slightly exceeded the limit adopted by Brazilian legislation for groundwater. In general, surface waters showed large pH range (6 to 10.8), and changes caused by acid drainage in the chemical composition of these waters were not very significant. Locally, acid drainage seemed to have dissolved carbonate rocks present in the local stratigraphic sequence, attenuating the dispersion of metals and As. Stream sediments presented anomalies of these elements, which were strongly dependent on the proximity of tailings piles and abandoned mines. We found that precipitation processes in sediments and the dilution of dissolved phases were responsible for the attenuation of the concentrations of the metals and As in the acid drainage and river water mixing zone. In general, a larger influence of mining activities on the chemical composition of the surface waters and sediments was observed when enrichment factors in relation to regional background levels were used.

Living Our Lives on the Edge: Power, Space and Sexual Orientation in Cape Town Townships, South Africa

Much of social science literature about South African cities fails to represent its complex spectrum of sexual practices and associated identities. The unintended effects of such representations are that a compulsory heterosexuality is naturalised in, and reiterative with, dominant constructions of blackness in townships. In this paper, we argue that the assertion of discreet lesbian and gay identities in black townships of a South African city such as Cape Town is influenced by the historical racial and socio-economic divides that have marked urban landscape. In their efforts to recoup a positive sense of gendered personhood, residents have constructed a moral economy anchored in reproductive heterosexuality. We draw upon ethnographic data to show how sexual minorities live their lives vicariously in spaces they have prised open within the extant sex/gender binary. They are able to assert the identities of moffie and man-vrou (mannish woman) without threatening the dominant ideology of heterosexuality.

Novel Primate-Specific Genes, RMEL 1, 2 and 3, with Highly Restricted Expression in Melanoma, Assessed by New Data Mining Tool

Melanoma is a highly aggressive and therapy resistant tumor for which the identification of specific markers and therapeutic targets is highly desirable. We describe here the development and use of a bioinformatic pipeline tool, made publicly available under the name of EST2TSE, for the in silico detection of candidate genes with tissue-specific expression. Using this tool we mined the human EST (Expressed Sequence Tag) database for sequences derived exclusively from melanoma. We found 29 UniGene clusters of multiple ESTs with the potential to predict novel genes with melanoma-specific expression. Using a diverse panel of human tissues and cell lines, we validated the expression of a subset of three previously uncharacterized genes (clusters Hs.295012, Hs.518391, and Hs.559350) to be highly restricted to melanoma/melanocytes and named them RMEL1, 2 and 3, respectively. Expression analysis in nevi, primary melanomas, and metastatic melanomas revealed RMEL1 as a novel melanocytic lineage-specific gene up-regulated during melanoma development. RMEL2 expression was restricted to melanoma tissues and glioblastoma. RMEL3 showed strong up-regulation in nevi and was lost in metastatic tumors. Interestingly, we found correlations of RMEL2 and RMEL3 expression with improved patient outcome, suggesting tumor and/or metastasis suppressor functions for these genes. The three genes are composed of multiple exons and map to 2q12.2, 1q25.3, and 5q11.2, respectively. They are well conserved throughout primates, but not other genomes, and were predicted as having no coding potential, although primate-conserved and human-specific short ORFs could be found. Hairpin RNA secondary structures were also predicted. Concluding, this work offers new melanoma-specific genes for future validation as prognostic markers or as targets for the development of therapeutic strategies to treat melanoma.

Data Mining Applied to Harmonic Current Sources Identification in Residential Consumers

This work proposes a method based on both preprocessing and data mining with the objective of identify harmonic current sources in residential consumers. In addition, this methodology can also be applied to identify linear and nonlinear loads. It should be emphasized that the entire database was obtained through laboratory essays, i.e., real data were acquired from residential loads. Thus, the residential system created in laboratory was fed by a configurable power source and in its output were placed the loads and the power quality analyzers (all measurements were stored in a microcomputer). So, the data were submitted to pre-processing, which was based on attribute selection techniques in order to minimize the complexity in identifying the loads. A newer database was generated maintaining only the attributes selected, thus, Artificial Neural Networks were trained to realized the identification of loads. In order to validate the methodology proposed, the loads were fed both under ideal conditions (without harmonics), but also by harmonic voltages within limits pre-established. These limits are in accordance with IEEE Std. 519-1992 and PRODIST (procedures to delivery energy employed by Brazilian`s utilities). The results obtained seek to validate the methodology proposed and furnish a method that can serve as alternative to conventional methods.
