The purpose of this study is to identify, analyze, and describe the social outcomes that may be affected by the environmental risks generated by infrastructure projects; to examine the ways in which vulnerability and exposure to hazards may increase risk in neighborhoods over time; and to examine the implications of addressing the exacerbation of exposure to natural hazards within the traditional environmental justice framework. The Industrial Canal and Lower Ninth Ward were selected as the subjects of this case study because the canal has existed on the perimeter of the neighborhood for nearly one century, isolating Lower Ninth Ward residents from the rest of New Orleans and significantly contributing to two catastrophic flood events. The findings of the study are as follows: (1) the environmental risks associated with infrastructure projects can be magnified when imposed on an already vulnerable neighborhood, and may ultimately result in hazard events which cause displacement and disinvestment. Such consequences can have an impact on micro-level (individual and household) and macro-level (neighborhood) social outcomes; (2) vulnerability and exposure to hazards can initiate a pattern of increased risk that intensifies vulnerability to subsequent hazard events; and, finally, (3) the parallels between the causes and consequences of traditional environmental justice issues and the exacerbation of exposure to natural hazards implies that framing issues relative to natural hazards as matters of justice and articulating the social consequences of not mitigating such hazards can be an excellent way of educating stakeholders and lobbying for resources.

Diepsloot, a township in Johannesburg, South Africa, was used as a case study to explore the perceptions of people in informal settlements towards their role in limiting pollution in their environment. The method followed was qualitative, and primary data were collected through the use of key informants (Ward Councillor and Environmental Health Officer), and three focus groups. Diepsloot is a marginalised residential area located in the Northern perimeter of the City of Johannesburg. The settlement is spatially fragmented, reflects a high residential density and is plagued with high levels of unemployment and poverty. Compounded by poor municipal service delivery, these challenges lead to a range of environmental problems such as overflowing solid waste on the streets, water pollution, and high levels of indoor air pollution. The study found that there were varying levels of commitment to limiting pollution by people in the informal settlement. This (commitment to limiting pollution) was largely dependent on community action through the formation of street committees. In streets where there was community cohesion, street committees were stronger and environmental conditions were better. In contrast, environmental problems were worse where street committees were weak or not operating. Regarding the role of government, the major constraints leading to unresponsive interventions were the limited scale of municipal operation and their poor communication with residents. Suggested corrective measures include recycling, education on pollution and the need for institutional strengthening. Further research aimed at identifying a set of appropriate partnerships and institutions needed for responsive interventions in informal settlements is required.

Even if one is confident that the staff provide the bestpossible treatment, being admitted into hospital is still astressful situation. In recent decades, architecturalresearchers have elaborated on aspects of the patient'sperspective where the design of the physical environment maypositively enhance the healing experience. The emergingunderstanding reveals that this is not an issue to be solvedsimply by decorative design, for it entails the spatialinterpretation and integration of broader and deeper facets ofhuman response, within which suffering, empathy andprofessional care are embraced. This thesis elucidates the patients' use of space accordingto their cultural perceptions in two inpatient wards in aregional hospital in northwestern Namibia. The study appliescase study methodology with the focus on the interactionbetween patients, visitors and nursing staff in relation to thephysical environment. The theoretical basis within medical anthropologyconceptualises sickness as a cultural event in the dual notionillness and disease, signifying two ways of understandingsickness, the individual and the professional interpretations.The Foucauldian theory on discipline and space suggests thatthe biomedical discipline is spatially represented by themodern hospital, from which aspects of illness areexcluded. The results show that circumstances in the physicalenvironment highly influence the patients' illness experienceby possessing certain qualities or by the activities renderedpossible by spatial conditions. The two wards possess manymodern qualities adding to an enclosed and restrictingenvironment. Patients come from a culturally dynamic andchanging context where new approaches to healthcare andhospital physical space are generated. Whereas patients haveintegrated hospital-based biomedicine as a medical alternative,modern hospital space cannot accommodate certain patient needs.Patients, visitors and nursing staff negotiate space in orderto overcome spatial weaknesses. Family members' overnightaccommodation in the hospital, as well as their voluntarycontribution to patient care, are two important aspects whichare not spatially incorporated. An alternative ward design is suggested in which patients'and family members' active participation in the healing processis encouraged, with support from the nursing staff. The higherflexibility the design offers caters for the spatialintegration of future hybrid processes.

Il aura fallu plusieurs années après que l'idée d'une transition de phase à température nulle émerge pour que l'on comprenne l'impact d'un tel point critique quantique sur une vaste région du diagramme de phase. Observé dans de nombreux exemples expérimentaux, ce régime critique quantique n'est toutefois pas encore bien compris sur le plan théorique et nécessite de nouvelles approches. Dans une première partie, nous nous intéressons au point critique quantique ferromagnétique. Après avoir construit une approche contrôlée permettant de décrire le régime critique quantique, nous montrons au travers de la susceptibilité statique de spin que le point critique quantique ferromagnétique est instable, détruit par une interaction effective dynamique à longue portée générée par l'amortissement de Landau des fluctuations de spin. Dans une seconde partie, nous revisitons le cas d'une impureté Kondo exactement écrantée avec une représentation bosonique du spin local et dans une limite de grande dégénérescence de spin N. Nous montrons que dans ce régime, l'état fondamental est un liquide de Fermi non-trivial contrairement à ce qui était communément admis. Nous étendons alors notre méthode au cas de deux impuretés couplées où nos résultats coincident qualitativement avec les approches déjà existantes. Ensuite, nous développons un formalisme de Luttinger-Ward capable de pallier certains défauts de l'approche originale pour la description d'une impureté isolée. Enfin, nous détaillons les bases ainsi que les premiers résultats de l'extension à un réseau Kondo de moments locaux, pertinent pour la compréhension du régime critique quantique des matériaux de type fermions lourds.

L'identification passive d'un système réside dans l'estimation des paramètres qui décrivent ce système uniquement à l'aide de sollicitations ambiantes. Dans le génie civil, cette discipline est appliquée pour le suivi de l'état de santé des structures, on parle de SHM (Structural Health Monitoring) passif. Le SHM passif est généralement réalisé à l'aide d'une instrumentation déployée en surface. La thèse s'est intéressée aux possibilités offertes par une instrumentation qui serait enfouie. Dans une première partie, on établit les résultats associés à l'identification passive des milieux visco-élastiques. L'originalité de ces travaux réside dans la prise en compte d'un modèle de dissipation réaliste, la viscosité, ainsi que du caractère vectoriel des ondes élastiques. Ces résultats théoriques sont validés expérimentalement et démontrent la portabilité du SHM passif en surface au SHM passif en volume. Dans une deuxième partie, on s'intéresse à deux problèmes attachés à l'enfouissement de capteurs: l'estimation passive de leur position (problème SNL, Sensor Network Location problem) et de leur attitude (problème SNA, Sensor Network Attitude problem). Ces problèmes sont résolus grâce à l'identification passive qui fournit, en plus d'information physique sur le milieu, des informations géométriques sur le réseau. En particulier, on peut estimer des distances et des attitudes relatives entre capteurs. A l'aide de ces informations partielles et bruitées, des algorithmes de résolution des problèmes SNL et SNA ont été développés puis validés expérimentalement. Enfin, on synthétise l'apport de la thèse et on identifie les verrous technologiques à lever afin de justifier la faisabilité de l'enfouissement d'un réseau de capteurs dans le but de faire du SHM passif.
