A Corporate View of Housing and Community in a Company Town: Copper Cliff, 1886 to 1920.

Goltz, Eileen January 1990 (has links)
Traces the development of the company town of Copper Cliff (now part of Sudbury), Ontario, to show how a corporation viewed the purpose of such a community and how it was used to meet company ends. Copper Cliff was a settlement around the copper mines of the Canadian Copper Company. A highly pragmatic solution to the problem of getting workers to resettle in out-of-the-way places, these towns usually had their houses, water and systems, schools, roads, stores, and entertainment centers built and financed by the primary company operating in the area. To the company, the housing and the town in general were investments, and also a 'tool' for controlling workers. / Based on company records and local archives; 6 tables, 8 illus., 72 notes.

The Glass Cliff: Differences In Perceived Suitability And Leadership Ability Of Men And Women For Leadership Positions In High And Poor Performing Companies

Uyar, Esra 01 August 2011 (has links) (PDF)
The purpose of this thesis was to investigate perception of glass cliff in a Turkish sample. Glass cliff refers to a phenomenon whereby women are over-represented in risky leadership positions. Thus, the current study explored the effect of company performance and candidate gender on perceived suitability and on perceived leadership ability of the candidate for the leadership position. The thesis also examined moderating effects of ambivalent sexism (hostile and benevolent sexism) on the relationship between company performance and perceived suitability as well as on the relationship between company performance and perceived leadership ability of the female candidate. The data were collected from 167 MBA students through quantitative methods. The results of the analyses indicated that compared to an equally qualified male candidate, female candidate was perceived as more suitable and more able as a leader when the company performance was declining. Moreover, the female candidate was perceived as more able when the company performance was declining rather than improving. Participants evaluated the male candidate as more suitable when the company performance was improving rather than declining. The results of the moderation analyses revealed that declining company performance predicted an increase in perceived suitability and leadership ability of the female candidate for the participants who have low benevolent sexism scores. The major contributions of the present study are (1) examining the perception of glass cliff phenomenon for the first time in Turkey, and (2) showing the impact of benevolent sexism on glass cliff.

Apport d'une base de données d'éboulements rocheux obtenues par scanner laser dans la caractérisation des conditions de rupture et processus associés / Contribution of rockfall databases obtained by laser scanner in the characterization of failure conditions and process

D'amato, Julie 15 December 2015 (has links)
Ce travail de thèse a consisté à établir une base de données d'éboulements rocheux la plus exhaustive possible (pour des volumes supérieurs à 0,1 m3) pour une paroi rocheuse active dominant l'agglomération grenobloise, en utilisant des données de scanner laser et de photographie. Le site d'étude est une falaise calcaire de plusieurs kilomètres en bordure du massif de la Chartreuse, constituée de deux barres de morphologies différentes, l'une en calcaire lité, l'autre en calcaire massif.Les nuages de points issus du scanner laser permettent de reconstituer la falaise et les compartiments éboulés en 3D. Les données de surface des falaises, ainsi que des informations sur la localisation, les dimensions, le mécanisme de rupture propre à chaque compartiment ont été analysées pour caractériser l'évolution morphologique des deux falaises. Il apparait que la falaise inférieure, dont la morphologie dépend fortement de la fracturation et de l'érosion torrentielle des marnes sous-jacentes, présente une fréquence d'éboulement 22 fois plus importante que la falaise supérieure, de morphologie et pente régulière. De plus, dans la falaise inférieure, le taux d'érosion est 4 fois plus élevé entre 900 et 1000 m d'altitude, qu'entre 1000 et 1100 m. Cela montre que le régime d'érosion de cette falaise est transitoire, alors que celui de la falaise supérieure pourrait être permanent.Les éboulements rocheux détectés ont également été datés par un suivi photographique pendant 2,5 ans. Un suivi quasi-continu (1 photo toutes les 10 min), avec un objectif grand angle a permis de dater 214 éboulements de plus de 0,1 m3. Un suivi mensuel, avec un téléobjectif, a permis de dater 854 éboulements de plus de 0,01 m3. L'analyse de ces deux bases de données montre que la fréquence d'éboulements rocheux peut être 7 fois plus grande lors d'un épisode de gel-dégel que sans évènement météorologique particulier, et 4,5 fois plus grande lors d'un épisode de pluie. De plus, elle devient 26 fois plus grande si l'intensité depuis le début de l'épisode est supérieure à 5 mm/h. A partir de ces résultats, une échelle de 4 niveaux d'aléa a pu être proposée pour la prévision de l'aléa. La base de données plus précise et la définition des épisodes de gel-dégel ont permis de distinguer différentes phases dans un épisode de gel-dégel : refroidissement à température négative, réchauffement à température négative, et dégel (à température positive). Il apparait que les éboulements rocheux se produisent plus fréquemment lors des périodes de réchauffement (à température négative) et de dégel que lors des périodes de refroidissement. Cela suggère que les éboulements sont causés par la dilatation thermique de la glace plutôt que par la dilatation due au changement de phase. Ils peuvent cependant ne se produire que lors du dégel, car la cohésion de l'interface roche-glace peut être suffisante pour tenir le bloc jusqu'à la fonte de la glace. Des expériences in situ et en laboratoire ont permis de mesurer la pression de glace dans une fissure avec écoulement d'eau. Elles montrent que la glace formée par accrétion (gel de gouttes ou films d'eau) n'exerce pas de pression sur les parois rocheuses. / Using laser scanner data, an exhaustive rockfall database (for volume larger than 0.1 m3) has been established for a rockwall located near the town of Grenoble (France). The study site is a long double cliff, on the eastern border of the Chartreuse Massif. The two cliffs consist respectively of thinly bedded and massive limestone, which show different structures, morphologies and rockfall activities.The 3D point clouds obtained by laser scanner allow to detect and model the fallen compartments in 3D. Information about cliff surface, and localization, dimensions, failure mechanism for each compartment were obtained and analyzed in order to characterize the morphological evolutions of the two cliffs. It appears that the morphology and the slope of the lower cliff is related to fracturing and torrential erosion which occurs in the marls below the cliff. The rockfall frequency for this lower cliff is 22 times higher than for the upper cliff. Moreover, in the lower cliff the erosion rate is at least 4 times higher for an elevation between 900 and 1000 m than between 1000 and 1100 m. These results show that the erosion process in the lower cliff is in a transient state, whereas it could be in a steady state in the upper cliff. The morphology and the slope of the upper cliff is more regular than for the lower cliff.Rockfalls have been dated by photographic surveys during 2.5 years. A near-continuous survey (1 photo each 10 mn) with a wide-angle lens have allowed dating 214 rockfalls larger than 0.1 m3, and a monthly survey with a telephoto lens, dating 854 rockfalls larger than 0.01 m3. The analysis of the two data bases shows that the rockfall frequency is 7 times higher during freeze-thaw episodes than without meteorological event, and 4.5 times higher during rainfall episodes. Moreover, it becomes 26 times higher when the mean rainfall intensity (since the beginning of the rainfall episode) is higher than 5 mm/h. Based on these results, a 4-level hazard scale has been proposed for hazard prediction. The more precise data base and freeze-thaw episode definition make it possible to distinguish different phases in freeze-thaw episodes: negative temperature cooling periods, negative temperature warming periods and thawing periods. It appears that rockfalls occur more frequently during warming and thawing periods than during cooling periods. It can be inferred that rockfalls are caused by thermal ice dilatation rather than by dilatation due to the phase transition. But they may occur only when the ice melt, because the cohesion of the ice-rock interface can be sufficient to hold the failed rock compartment until the ice melt. The formation of ice in rock cracks has been studied in the field and in laboratory to highlight its influence on rockfall triggering. It has been shown that ice forming by an accretion process (freezing of water drops) doesn't exert a pressure on the crack walls.

The Echo Cliff structure: identification and analysis of a possible Kansan impact structure

Lane, Adam Eldon January 1900 (has links)
Master of Science / Department of Geology / Abdelmoneam Raef / Matthew W. Totten / This study examines an ovoid drainage feature southwest of Topeka, Kansas, whose discovery sparked a flurry of activity. Geomicrobial and surface gamma ray surveys indicated possible vertical migration of hydrocarbons, and a ground magnetic survey produced anomalies that resemble the profile of a crater. The area was dubbed the Echo Cliff structure and considered analogous to the Ames structure in Oklahoma, an Ordovician impact structure remarkable for significant hydrocarbon recovery. However, four wells drilled in the area were dry and abandoned. The Echo Cliff structure did yield further indications of its origins by the discovery of possible shocked quartz in drill cuttings from the Ordovician Simpson Group. Our study integrated well log analysis, geophysical modeling, and petrographic analysis to verify or refute the proposed identity of the Echo Cliff structure. Well logs from the area were used to create a structural and stratigraphic cross-section in Petrel® 2016. A gravity survey was conducted in the study area and combined with an aeromagnetic survey, donated by Applied Geophyics, Inc., to use as the basis for geophysical modeling within GM-SYS®. Finally, drill cuttings from the Simpson Group of two wells in the study area were mounted for thin sectioning. These thin sections were examined for planar deformation features, which are indicative of an impact event. The structural and stratigraphic cross sections indicated minimal variation in the subsurface, which is uncharacteristic of an impact event. The GM-SYS® geophysical models seem to indicate that variations in the topography of the Precambrian basement and faulting from the Bolivar-Mansfield Tectonic Zone are responsible for the geophysical anomalies and possibly the current drainage pattern of the study area. Finally, no planar deformation features were observed in any of the examined thin sections. Therefore, there is currently no evidence in support of the claim that the Echo Cliff structure is an impact structure.

On the coast of Fortim, the sea cliffs are distributed in the coastal plain and along the left bank of the river Jaguaribe, where you can see the highest population density and concentration of infrastructure associated with the tourism. The research is inserted in the municipality of Fortim, the main spatial extent its sea cliffs coastline, compartmentalized into three sectors of study, occupying in total an area of 7.089.3 hectares (70, 89 km²), for which was held analysis of landscape dynamics in an integrated way, linking the environmental aspects of the socioeconomic conditions in order to contribute to environmental planning and management that are consistent with the reality in question. The research is headed in the analysis of the dynamics and typology of the landscape, following thus systemic assumptions from the theoretical and methodological foundations of Geoecology landscape. The research stages permeated the field research for application checklist and collection of environmental data, granulometric analysis of sediments, water analysis and cartographic products, which used RapidEye 2013 satellite images on the scales of 1: 40,000 and 1: 80,000. They were, in the stages mentioned, the sea cliffs of Fortim are formed by rocks of the Barreiras Group and in some sectors are associated with Formation Tibau rocks; generally they consist of medium sands and strongly cemented sandstones. Regarding the forms of use and occupation of coastal, activities were identified developed in Permanent Preservation Areas, such as shrimp farming in fluviomarinha plain of the river Pirangi, allotments and second homes, mainly on the tops of sea cliffs, contributing mainly to the mischaracterization of the landscape and the privatization of space. In some sectors, there is no occupation of the sea cliffs, however the small stretch of beach strip makes the vulnerable side to wave action. It was also noted, through physical, chemical and microbiological analyzes, the quality of water from community wells is committed to consumption, especially in areas of high population density. In this sense, one should promote the management of the area, being necessary to know the coastal carrying capacity with cliffs with a view to preventing and minimizing possible negative influence on natural systems and human populations that live in the surrounding areas of these environments. / As falésias são importantes morfologias no contexto paisagístico costeiro cearense, configurando-se em escarpas abruptas e instáveis nas zonas costeiras, influenciadas pelo fluxo eólico, pluvial e, principalmente, marinho, tendo sua formação associada, principalmente, à deposição dos sedimentos do Grupo Barreiras. No litoral de Fortim, as falésias estão distribuídas na planície litorânea e ao longo da margem esquerda do rio Jaguaribe, onde se pode notar maior adensamento populacional e concentração de infraestruturas associadas ao veraneio e ao turismo. A pesquisa se insere no Município de Fortim, tendo como principal abrangência espacial o seu litoral de falésias, compartimentado em três setores de estudo, que ocupam no total uma área de 7.089,3 hectares (70, 89 km²), para a qual se realizou análise da dinâmica paisagística de modo integrado, relacionando os aspectos físico-ambientais às condições socioeconômicas, a fim de contribuir para um planejamento e gestão ambiental que sejam compatíveis com a realidade em questão. A pesquisa se encaminhou na análise da dinâmica e tipologia da paisagem, seguindo, assim, pressupostos sistêmicos desde as bases teórico-metodológicas da Geoecologia da Paisagem. As etapas da pesquisa perpassaram os levantamentos de campo para aplicação de checklist e coleta de dados ambientais, análise granulométrica de sedimentos, análises de água e de produtos cartográficos, em que se utilizou imagens de satélite RapidEye 2013 nas escalas de 1:40.000 e 1:80.000. Verificou-se, nas etapas mencionadas, que as falésias de Fortim são formadas por rochas do Grupo Barreiras e em alguns setores estão associadas às rochas da Formação Tibau; em geral, são constituídas por areias médias e arenitos fortemente cimentados. Em relação às formas de uso e ocupação no litoral, foram identificadas atividades desenvolvidas em Áreas de Preservação Permanente, como a carcinicultura na planície fluviomarinha do rio Pirangi, loteamentos e segundas residências, principalmente, nos topos de falésias, que contribuem, sobretudo, para a descaracterização da paisagem e na privatização do espaço. Em alguns setores, não há ocupação nas falésias, contudo a pequena extensão da faixa de praia torna a vertente vulnerável à ação das ondas. Verificou-se, também, por meio de análises físico-químicas e microbiológicas, que a qualidade da água de poços comunitários encontra-se comprometida para consumo, principalmente nas áreas de maior adensamento populacional. Nesse sentido, deve-se promover o gerenciamento da área, sendo preciso conhecer a capacidade de suporte de litorais com falésias, com vistas a prevenir e minimizar possíveis influxos negativos aos sistemas naturais e às populações humanas que habitam o entorno desses ambientes.

Hiérarchisation des facteurs d'érosion des falaises côtières du site au globe / Ranking sea cliff eroding factors from site to global scale

Prémaillon, Mélody 06 December 2018 (has links)
Cette thèse a pour but de comprendre quels processus contrôlent l'érosion des falaises côtières à deux échelles spatiales. Nous avons d'abord réalisé une étude locale de la falaise de flysch de Socoa (Pays Basque), dont la spécificité est un fort contrôle structural. Elle a été suivie annuellement par photogrammétrie pendant 6 ans. Cette falaise résistante recule lentement, à 3,4 mm/an. Son erosion est le fait de départ de blocs, majoritairement au niveau des arêtes libres. Ensuite, afin d'aborder l'échelle globale, une base de données (GlobR2C2, Global Recession Rates of Coastal Cliffs) a été créée. Elle est la première à recenser les taux d'érosion publiés et à les comparer à des forçages météo-marins issus de grilles mondiales. Nous l'avons traitée par analyse statistique exploratoire et par random forest. La résistance de la roche parait être le premier facteur contrôlant le taux d'érosion. Au second ordre, apparaissent le nombre de jours de gel par an et le marnage. / The aim of this PhD is to understand factors controlling sea cliff erosion at both local scale, based on Socoa cliff (Basque country) and at global scale. The specificity of Socoa's flysch cliff is its strong structural control. A 6 year photogrammetric study from annual records was conducted. This resistant cliff erodes slowly at 3.4 mm/yr and rockfalls occur mostly at cliff edge. A database called GlobR2C2 (Global Recession Rates of Coastal Cliffs) was set up. It is the first one to compile erosion rate data extracted from literature and to compare it to marine and continental forcing, extracted from worldwide grids and reanalyses. It was statistically analysed through exploratory analysis and random forest. At global scale, rock resistance appears to be the primary factor controlling cliff erosion. Second orders factors are the number of frost day per year and the average tidal range.
