Five periods of ice advance in the North Klondike-upper Blackstone basins of the Ogilvie Mountains are recognized by the downvalley sequence of progressively older moraines. The youngest occurred during the last millennium and is represented by glacierets and fresh moraines. The other advances are of the Pleistocene Epoch; from youngest to oldest they are: Age I (valley glacier stage), Age II (transection glacier), Age IIA (transection glacier with piedmont) and Age III (mountain ice cap). Evidence for Age III is limited to the north slope of the ranges. Age IIA was recognized only on the north slope and may represent a slightly older pulse of the Age II. This chronosequence is tentatively correlated with those elsewhere in the northern Cordillera. Within the region an array of surficial elements indicates that a continuous and discontinuous mosaic of processes have operated interdependently during the Quaternary. A product of these processes is mapped under one of eight facies - attention being directed to the varieties of features associated with the glacial and periglacial cycles. Of the latter, active, inactive and degradational forms exist. Strong correlations between the distribution of some types of surficial features and the underlying bedrock geology are recognized. No changes in morphology, permafrost distribution, pebble weathering, pedogenesis and floral succession could be related to the ages of the Pleistocene moraines. The influence of permafrost on all ages of moraines, the variability in their environment of deposition, and an edaphic and climatic discontinuity produce greater differences than does the age factor. In the northern half of the study area, permafrost and associated phenomena were observed to greatly retard chemical alteration; on the other hand, they permit the development of only a vegetational and pedological "polyclimax", rather than a single mesic climax, in a time span of less than 11,000-15,000 years. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate

The history of trade among Indian groups of the Canadian Yukon has included changes in the quantity and type of goods involved and, more importantly, changes in the social relations between the people who conducted this trade. These relations were between distinct native groups at first, and later directly between Indians and White traders. In this study historical data on the changes in trade is organized into convenient stages by identifying types of trade institutions. Four such stages are described and analyzed with reference to the major conditioning factors for trade in the area and at the time. These stages are (1) Inter-tribal trade, when exchanges were conducted between partners of different native groups; (2) Trading chief trade, m which an Indian group leader handled relations with White traders; (3) Monopoly trade, in which a quasi-debt relationship handled trade between traders and individual trappers; and (4) Market trade, in which trade is handled through separate fur market and retail market institutions. Institutions are treated in this study as having a set of several purposes related to the complementary aims of participants. Changes between one stage and the next are seen as a regrouping of these purposes into new sets, which become the focus of hew institutions. This view of institutional change arises from an analysis of the changes in trade relations in the Yukon, and is compared with a somewhat similar analysis of social change developed "by Talcott Parsons and Neil Smelser. / Arts, Faculty of / Anthropology, Department of / Graduate

Ogilvie Mountains breccia (OMB) is in Early (?) to Late Proterozoic rocks of the Coal Creek Inlier, southern Ogilvie Mountains, Yukon Territory. Host rocks are the Wernecke Supergroup (Fairchild Lake, Quartet and Gillespie Lake groups) and lower Fifteenmile group. Distribution and cross-cutting relationships of the breccia were delineated by regional mapping. OMB was classified by clast type and matrix composition. Ogilvie Mountains breccia crops out discontinuously along two east-trending belts called the Northern Breccia Belt (NBB) and the Southern Breccia Belt (SBB). The NBB extends across approximately 40 km of the map area, and the SBB is about 15 km long. Individual bodies of OMB vary from dyke- and sill-like to pod-like. The breccia belts each coincide with a regional structure. The NBB coincides with a north side down reverse fault—an inferred ruptured anticline—called the Monster fault. The SBB coincides with a north side down fault called the Fifteenmile fault. These faults, at least in part, guided ascending breccia. The age of OMB is constrained by field relationships and galena lead isotope data. It is younger than the Gillespie Lake Group, and is at least as old as the lower Fifteenmile group because it intrudes both of these units. A galena lead isotope model age for the Hart River stratiform massive sulphide deposit that is in Gillespie Lake Group rocks is 1.45 Ga. Galena from veinlets cutting a dyke that cuts OMB in lower Fifteenmile group rocks is 0.90 Ga in age. Therefore the age of OMB formation is between 1.45 and 0.90 Ga. Ogilvie Mountains breccia (OMB) has been classified into monolithic (oligomictic) and heterolithic (polymictic) lithologies. These have been further divided by major matrix components—end members are carbonate-rich, hematite-rich and chlorite-rich. Monolithic breccias with carbonate matrices dominate the NBB. Heterolithic breccias are abundant locally in the NBB, but are prevalent in the SBB. Fragments were derived mainly from the Wernecke Supergroup. In the SBB fragments from the lower Fifteenmile group are present. Uncommon mafic igneous fragments were from local dykes. OMB are generally fragment dominated. Recognized fragments are up to several 10s of metres across and grade into matrix sized grains. Hydrothermal alteration has locally overprinted OMB and introduced silica, hematite and sulphide minerals. This mineralization has received limited attention from the mineral exploration industry. Rare earth element chemistry reflects a lack of mantle or deep-seated igneous process in the formation of OMB. However, this may be only an apparent lack because flooding by a large volume of sedimentary material could obscure a REE pattern indicative of another source. The genesis of OMB is significantly similar to modern mud diapirs. It is proposed that OMB originated from pressurized, underconsolidated fine grained limey sediments (Fairchild Lake Group). These were trapped below and loaded by turbidites (Quartet Group) and younger units. Tectonics and the initiation of major faults apparently triggered movement of the pressurized fluid-rich medium. The resulting bodies of breccia are sill-like and diapir-like sedimentary intrusions. Fluid-rich phases may have caused hydrofracturing (brittle failure) of the surrounding rocks (especially in the hanging wall). Breccia intrusion would have increased the width of the passage way while encorporating more fragments. Iron- and oxygen-rich hydrothermal fluids apparently were associated with the diapirism. Presumably these fluids are responsible for the high contents of hematite and iron carbonate in fragments, and especially, in the matrix of the breccias. Exhalation of these fluids may have formed the sedimentary iron formations that are spatially associated with the breccias. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate

In March of 1987, the Geologic Survey of Canada conducted a major seismic refraction experiment in the Mackenzie Delta-Southern Beaufort Sea-Northern Yukon area. This study involves the analysis of a portion of the resulting data set. A 2D velocity profile through the Richardson Mountains of the northern Yukon has been constructed using raytracing to model the travel-times and amplitudes. The line is approximately 320 km long, running from a shotpointon the Eagle Plains in the south to one 50 km offshore in Mackenzie Bay to the north, with an average receiver spacing of 3.5 km. An additional shotpoint is located at Shingle Point, on the shore of Mackenzie Bay. A series of four sedimentary basins separated by major structural highs produces a complex basement structure. Two distinct upper crustal layers were modelled, a 5.95 km/s layer overlying a 6.3 km/s layer, as well as a lower crustal layer with a velocity of 7.25 km/s. Crustal velocity gradients are low (≤ 0.005 s⁻¹). The 6.3 km/s layer pinches out beneath the Beaufort-Mackenzie Basin in the north, accompanied by a thinning of the lower crust from a thickness of 20 km in the south to less than 10 km beneath MB. This results in the crust as a whole thinning from a thickness of 50 km under the Richardson Mountains to only 40 km under the Beaufort-Mackenzie Basin. The velocity of the upper mantle is 7.95 km/s. The modelling of shear wave arrivals indicate Poisson's ratios of 0.23 ±0.02 in the upper crust and 0.25 + 0.02 in the lower crust. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate

The Master's thesis is focused on the migration of population within the Czech republic. The migration flows within each individual region are explored and compared with selected economic indicators of the regions. Regions of the Czech republic are chosen as the main units for analysis, complemented by research on individual counties. The analysis highlights key trends in spatial movement of the population in the recent years. Subsequently the analysis focused on, whether the population movement is associated with an economic attractiveness of given administrative unit. The hypothesis being whether the increase in economic indicators of an administrative unit is follow by an increase in migration inflows to that unit. This hypothesis was not confirmed in any of the analyzed regions; only a weak correlation was established.

This study addressed the social determinants of health with a specific focus on three factors in the social environment that either individually or collectively have an influence on health status: gender, socioeconomic status (SES), and people's social relationships. The purpose of the study was to examine whether people's social relationships mediate the effects of SES on self-rated health status and to assess whether these effects differ for women and men. The research questions were examined by formulating a theoretical model and evaluating the hypothesized relationships through the use of structural equation modelling. The analyses were conducted using LISREL on data from 1,239 non-First Nations Yukon residents who participated in the Territory's 1993 Health Promotion Survey. The results of this study suggest that household income significantly affected women's and men's health by influencing aspects of their social relationships. A higher overall rating of the quality of one's social relationships was associated with positive health ratings for both women and men while the perception that support would be available if needed significantly affected only women's self-ratings of their health. Received social support was negatively associated with women's health, but not men's, suggesting that the context in which support is received has an important influence on women's health. Relationship strain, as measured by care provided to several sources, was not significantly related to women's or men's health-ratings. The analyses also identify important interrelationships among the dimensions of social relationships studied as well as some gender differences among these relationships. For both women and men, positive evaluations of the importance of social relationships for their health and a greater number of social ties significantly influenced ratings of the overall quality of their social relationships. Having more social ties also positively influenced the perception of availability of social support for both women and men. The quality of their social relationships influenced the perceived availability of social support only for women. Given the focus of provincial and federal governments in seeking reform of their health-care systems, attention to modifiable determinants of health presents an opportunity to contribute to this reform process. The findings of this study contribute to our understanding of the effects of SES on health by providing support for gender interactions in a set of relationships where aspects of people's social relationships mediate the effects of income on health status. These findings provide support for gender-specific mechanisms by which income level influences perceived health status by shaping people's social relationships, the quality of those relationships and the support they offer. / Graduate and Postdoctoral Studies / Graduate

A tese realiza estudo sobre a mediação dos movimentos sociais na produção social do território, referenciado na perspectiva histórico-dialética. Relativamente às técnicas de pesquisa, selecionou-se uma referência bibliográfica, além da documental, apoiouse ainda em dados empíricos que foram coletados por meio de entrevistas, as quais realizaramse no Assentamento Cajueiro, em Parnaíba-PI. A história do Assentamento se estrutura em paralelo à implantação de projetos agrícolas de grande porte, como aqueles, realizados no município, no âmbito do plano de desenvolvimento proposto ao território. Explora-se elementos sobre o processo de organização de homens e mulheres, desde o período de ocupação da área até a consolidação do assentamento dando ênfase à mediação dos movimentos sociais, especialmente o Movimento dos Trabalhadores Rurais Sem Terra, na contínua negociação por seus direitos, o qual, o é neste sentido, o principal mobilizador e também mediador das conquistas dos residentes no assentamento. A pesquisa apresenta questões de gênero tramadas nesse processo, considerando as demandas das mulheres e o atendimento via ações públicas. Identifica-se a dificuldade de organização dos residentes no Assentamento, que assumem as atividades internas e, ao mesmo tempo buscam outras formas de remuneração temporária, na produção de frutas do Projeto de Irrigação. A proposta de desenvolvimento rural, em curso, vem aprofundando as desigualdades através de um planejamento territorial que direciona sua produção para o mercado externo, enquanto o assentamento permanece à margem das ações do Estado. / The analysis of the environmental and gender inequality addresses issues concerning the different processes of historical socio-use, production and struggle for ownership of land by men and women. The thesis conducts study on the mediation of social movements in social production of territory, referenced in historical and dialectical perspective. With regard to research techniques, selected a literature reference, in addition to the documentary, also supported it on empirical data were collected through interviews, which took place in the Assentamento Cajueiro in Parnaíba-PI. The history of the settlement is structured in parallel to the implementation of large-scale agricultural projects, such as those carried out in the city, under the development plan proposed to the territory. It explores elements of the process of organization of men and women from the period of occupation of the area until the consolidation of the settlement walk emphasis on mediation of social movements, especially the Movimento dos Trabalhadores Rurais Sem Terra in continuous trading for their rights, which, it is in this sense, the main mobiliser and also mediator of the achievements of residents in the settlement. The research presents gender concocted this process, considering the demands of women and care via public actions. Identifies the difficulty of organizing residents in the settlement, which take the internal activities and at the same time seeking other forms of temporary compensation, in fruit Irrigation Project. The proposed rural development programs in place has deepened inequalities through a territorial planning that directs its production to foreign markets, while the settlement remains on the margins of state actions.

This dissertation is an effort to understand the processes and systems housed within the infrastructure of a dynamic urban environment. Jeppestown, or Jeppe, as it is known by its inhabitants, is a post-industrial wasteland on the eastern outskirts of Johannesburg CBD (central business district). This rich cultural landscape was formed over generations by optimistic prospectors intrigued by the illusion of riches posed by the City of Gold. The project is focused on linking and transforming voids within the urban fabric, which are threatened by gentrification, into a healthy and productive network of public space. Guided by mapping and observation techniques, the designer can formulate the conception for a landscape architectural intervention aimed at maintaining and amplifying certain aspects coinciding with the ritualistic activities of everyday life as established within Jeppestown. Anchored by a series of social and economic nodes, a spinal development emerges, addressing thresholds between public and private realms by investigating edges as vessels for environmental and social systems. The designer uses a combination of existing characteristics of this urban artefact and newly introduced sustainable design principles to carve a coherent and productive public environment from an amalgamated entity termed the landscape slate. / Dissertation (ML(Prof))--University of Pretoria, 2014. / Architecture / ML(Prof) / Unrestricted

Subsequently, the realization of policies, theoretically, aimed at nature conservation, guided by the concept of sustainable development, created the necessary condition for maintaining the hegemonic production mode, starting from the harmony between economic growth and environmental conservation. In Acre, it is from 1999 the sustainable development takes shape as the main political element of government management of the Popular Front. Among the various projects supported by the government at the time, was the implementation of Programs to Reduce Emissions from Desforestation and Degradation (REDD), based on the sale of carbon to central countries as a menas of guaranteeing the process of acumulation and expansion of the model and legitimization of the Green Economy. At Seringal Itatinga, in Manoel Urbano, it officially becomes the territory for the implementation of these policies in 2010, with the Purus Tropical Forest Conservation Project. However, the reports of community members state that far from what was initially proposed, the interests of the large financiers and landowners involved in the project are prioritized, forming a scenario of territorial, human and symbolic violations by imposing a land use model that it does not match the traditional and historical knowledge of the community.

Dépendance des personnes âgées et devise républicaine : quelles articulations ? Cette thèse examine l'accompagnement professionnel de la dépendance, sujet d'intérêt public, au regard des principes républicains de liberté, d'égalité dont procède l'équité territoriale et de fraternité, dont découle la solidarité. La démarche géographique, innovante sur cet objet, analyse l'offre professionnelle en France métropolitaine de manière transversale, selon des méthodes quantitatives et qualitatives, et à plusieurs échelles territoriales. Il s'agit d'étudier la territorialisation de l'accompagnement des personnes âgées, c'est-à-dire son appréhension à partir de réalités spatiales et des processus afférents. Trois axes sont retenus. D’abord, les termes majeurs de l'étude, tels vieillissement ou dépendance, outre des chiffres-clés nationaux, sont éclairés par des réalités historiques et des témoignages d'acteurs, dans des perspectives nationales et locales. Une analyse de l'organisation actuelle de l'offre à destination des personnes âgées dépendantes est réalisée, incluant aides à domicile et auxiliaires de vie sociale, services de soins infirmiers à domicile et infirmiers libéraux, établissements d'hébergement pour personnes âgées dépendantes, ainsi que les structures de coordination. La seconde partie de la thèse se polarise sur les ancrages territoriaux de l'offre professionnelle. Certes, les offres étudiées sont de proximité, en témoigne leur comparaison avec d'autres types d'équipements. Leur présence dans les départements n'est cependant pas homogène, les infirmiers libéraux sont par exemple davantage présents dans les départements du littoral méditerranéen, quand les aides à domicile et auxiliaires de vie sociale interviennent davantage dans les départements du Nord de la France. Entre complémentarités et substitutions, cette recherche étudie les enjeux économiques, sociaux et politiques découlant d'une répartition spatiale différenciée. Dans la dernière partie de thèse, deux thèmes révélateurs sont approfondis. Le non-recours à l'Allocation personnalisée d'autonomie à domicile, prestation solidaire de compensation de la dépendance attribuée par les Conseils départementaux sur demande de la personne est d’abord étudié. Ensuite, les déterminants des migrations des personnes lors de leur entrée en EHPAD. La difficulté est induite par le fait que de mêmes comportements, de non-recours ou de migrations, peuvent à la fois refléter les choix des personnes, et une défaillance des pouvoirs publics à proposer une offre adaptée et disponibles sur les territoires. Une analyse des déterminants individuels, appuyée sur des bases de données détaillées et sur les témoignages d'acteurs locaux permet de distinguer la limite entre liberté individuelle et responsabilité des pouvoirs publics. Cette étude produit des diagnostics territorialisés, outils potentiels d'aide à la décision, pour la Drees qui en est le financeur et les quatre Conseils départementaux partenaires / This thesis is based upon the French republican principles of Freedom, Equality which proceeds the territorial Equity of and Fraternity, fromwhich ensues Solidarity. Their application is studied on a matter of public interest: the professional care of the elderly dependence of inmainland France. The geographical approach implemented is innovative on this object. It analyzes the professional offer in a transverse way, thanks to quantitative and qualitative methods, and on several territorial scales.This paper seeks to study the territorialisation of elderly care, that is to say its apprehension from spatial realities and relative processes. Mythesis is composed of three themed chapters. The first section of this paper will examine, the major terms of the study, such as ageing ordependence, in addition national key figures, are highlighted by historical realities and actors' testimonies, in national and local perspectives.An analysis of the current organization of the offer aimed at dependent elderly persons is realized, including at home caregiver and at homesocial workers, at home nursing services and private nurses, nursing homes, as well as the coordinating structures.The second part of this study focuses on the territorial anchoring of the professional offer. Although, the offers studied are mainly locals, asevidenced by their comparison with other types of organizations, their presence in departments (The term department in this case refers toFrench administrative divisions) is not however homogeneous. Indeed private nurses are more present for instance in the departments of theFrench Mediterranean coast, whereas at home caregivers and at home social workers intervene more in northern departments of France.Between complementarities and substitutions, this research investigates the economic, social and political stakes ensuing from adifferentiated territorial distribution.In the last part of this paper, two revealing themes are explored in-depth. Firstly the non take-of an important allowance to pay forprofessional care, attributed by the departmental Councils, at the request of the dependent elderly person is studied. Then, the determinants ofthe migrations of people during their entering to nursing homes are analyzed. The difficulty is due to the fact that the same behaviours, nontake-up of allowances or migrations, can reflect at the same time the choices of the people, and a failure of public authorities to propose asuitable offer available throughout the territory. An analysis of the individual determinants, based on detailed databases and on testimonies oflocal actors allows to distinguish the limit between personal freedom and responsibility of public authorities.This study produces diagnoses by territories, it is a potential decision-making tool, for D.R.E.E.S (which stands for French NationalDepartment for Research, Studies, Evaluation and Statistics, Ministry of Health) and four departmental Councils partners
