A Sociological Approach to Indoor Environment in Dwellings : Risk factors for Sick Building Syndrome (SBS) and Discomfort

Engvall, Karin January 2003 (has links)
The principal aim was to study selected aspects of indoor environment in dwellings and their association with symptoms compatible with the sick building syndrome (SBS). A validated questionnaire was developed specifically for residential indoor investigations, using sociological principles and test procedures. The questionnaire was mailed to 14,243 multi-family dwellings in Stockholm, selected by stratified random sampling. Females, subjects with a history of atopy, those above 65 y, and those in new buildings reported more symptoms. Subjects owning their own dwelling had less symptoms. A multiple regression model was developed, to identify residential buildings with a higher than expected occurrence of SBS. In total, 28.5% reported at least one sign of building dampness in their home (condensation on windows, humidity in the bathroom, mouldy odour, water leakage). All indicators of dampness were related to symptoms, even when adjusting for demographic data, and other building characteristics (OR=2.9-6.0). Associations between symptoms and other building data was evaluated in older houses, built before 1961. Subjects in older buildings with a mechanical ventilation system had fewer symptoms. Heating by electric radiators, and wood heating was associated with an increase of most types of symptoms (OR=1.2-5.0). Multiple sealing measures (OR=1.3), and major reconstruction (OR=1.1-1.9), was associated with an increase of symptoms. The effect of seasonal adapted ventilation (SAV) was studied in a small experimental study. A 20% reduction of ventilation flow from 0.5-0.8 ac/h to 0.4-0.5 ACH during the heating season increased the perception of poor indoor air quality in the dwelling in general, and in the bedroom. In conclusion, low building age, and building dampness in the dwelling are associated with SBS. In older houses, mechanical ventilation is beneficial. The thesis did not support the view that energy saving measures in general is an important risk factor for SBS, but major reconstruction and multiple sealing measures can be risk factor for symptoms. Reducing the outdoor ventilation flow below the current Swedish ventilation standard (0.5 ACH) may increase the perception of impaired air quality.

Contested Landscapes/Contested Heritage : history and heritage in Sweden and their archaeological implications concerning the interpretation of the Norrlandian past

Loeffler, David January 2005 (has links)
This case study explores how geo-political power structures influence and/or determine the conception, acceptance and maintenance of what is considered to be valid archaeological knowledge. The nature of this contingency is exemplified through an examination of how the prehistory of Norrland, a region traditionally considered and portrayed as peripheral vis-à-vis the centre-South, was interpreted and presented by Swedish archaeologists during the 20th century. This contextual situation is analysed through the implementation of three interrelated and complimentary perspectives; 1) The relationship between northern and southern Sweden is examined using concepts concerning the nature of colonialism, resulting in the formulation of 20 particulars that typify the colonial experience, circumstances that characterise the historical, and unequal, association that has existed between these two regions for the last 600 years. 2) Ideals of national identity and heritage as manufactured and employed by the kingdom and later by the nation-state, with the assistance of antiquarianism, archaeology and/or centralised cultural management, are outlined. The creation of these various concepts have reinforced and perpetuated the colonial and asymmetrical association between what has naturally come to be viewed as the peripheral-North and the centre-South. 3) A century of archaeological research into the Norrlandian past is studied using the concepts ‘thoughtstyle’ and ‘thought-collective’ as devised by Ludwik Fleck. This analysis disclosed a persistent set of reoccurring explanations that have constantly been invoked when interpreting and presenting the prehistory of Norrland. This archaeological thought-style has normalised the unbalanced power relationship between North and South that has existed for the last 600 years by projecting it far back into the prehistoric past. This case study has demonstrated that archaeologists, unless acutely aware of the historical context in which they themselves move and work, risk legitimising debilitating economic and political power relationships in the present through their study and presentation of the past.

Rede of reeds : land and labour in rural Norfolk

Woolley, Jonathan Paget January 2018 (has links)
The central aim of this thesis is to provide a detailed ethnographic account of the human ecology of the Broads - a protected wetland region in the East of England - focussing upon how working lives shape and are shaped by this reedy landscape. In conversations about the management of the Broads, the concept of "common sense" is a frequent trope; encompassing a wide range of associated meanings. But what are these meanings of "common sense" in English culture, and how do they influence the peoples of England, and landscapes in which they work? This thesis addresses these questions ethnographically; using academic and lay deployments of common sense as a route into the political economy of rural Norfolk. Based on 12 months of fieldwork in the Broads National Park, this thesis draws together interviews and participant observation with land managers of various kinds - including conservationists, farmers, gamekeepers, volunteers, gardeners, and administrators. Chapter 1 dissects the differences between academic and popular understandings of "common sense" as a phrase, and produces an ethnographically-derived, working definition. Chapter 2 examines the attitudes of farmers, establishing "the common" as a root metaphor for social and practical rectitude, actualised through labouring in a shared landscape. Chapter 3 explores how the common is sensed, reflecting upon the diverse sensoria afforded by different degrees of enclosure on a single nature reserve. Chapter 4 explores how the concept of common sense intersects with a prevailing culture of possessive individualism, creating a fragmented society in the Park, wracked by controversies over management. Chapter 5 examines bureaucracy in Broadland - frequently cast as the very antithesis of common sense. In the conclusion, we return to the title, and ask - what do the reeds have to say about land, labour, and human nature?

Communautés natives des fourmis de la litière en forêts naturelles de Guyane française et impact de la conversion forestière en plantations monospécifiques / Native communities of leaf-litter ant communities in natural forests of French Guiana, and impact of forest conversion in monocultural tree plantations

Groc, Sarah 09 December 2011 (has links)
Les fourmis sont des organismes cibles appropriés pour les études environnementales. Au cours de notre étude, nous nous sommes focalisés sur les fourmis de la litière via l'application de deux méthodes de récolte complémentaires selon le protocole all (ants of leaf litter). Dans les forêts naturelles de Guyane française, l'hétérogénéité environnementale et les perturbations structurent les communautés de fourmis de la litière en influençant la richesse, la diversité, l'abondance et la densité en espèces ainsi que les compositions taxonomique et fonctionnelle. Chaque type de formation végétale possède une communauté spécifique. La fragmentation et la conversion des forêts en plantations ont entrainé une altération plus ou moins profonde des communautés; cette variabilité est fonction du type d’agriculture et des espèces d'essences cultivées. Bien que l'altération des communautés se soit révélée maximale dans la plupart des monocultures, les plantations de cacaoyers ont un potentiel de conservation réel. Enfin, dans un contexte ou il est urgent de simplifier l'intégration des arthropodes dans les études de conservation, de contrôle et de suivi de la santé des écosystèmes terrestres, la méthode des réseaux de neurones est apparue comme un outil puissant pour mettre en évidence et analyser les patrons des communautés de fourmis. / Ants are reliable and relevant target organisms for environmental surveys. In our study, we focused on litter-dwelling ants through the use of two complementary sampling methods that were implemented according to the ants of leaf litter (all) protocol. In pristine forests of french guiana, leaf-litter ant communities are structured by environmental heterogeneity and natural perturbations - which influence species richness, diversity, abundance and density, as well as taxonomic and functional composition. This results in habitat-specific communities for each vegetal formation. Forest fragmentation and conversion into monocultures have led to a more or less deep alteration of the ant communities; this variability depends on the type of agricultural system and cultivated tree species. Although the intensity of community alteration peaked in tree monocultures, cocoa plantation exhibited a real potential for native species conservation. Finally, in the current context where simplifying the integration of arthropods into conservation programs as well as into surveys designed to monitor and manage the environment is critical, the use of neural networks appears to be a powerful tool for reliably highlighting and analyzing ant communities patterns.

Living in a World Heritage site: ethnography of the Fez medina (Morocco) / Habiter un site du patrimoine mondial: ethnographie de la médina de Fès (Maroc)

Istasse, Manon 23 September 2013 (has links)
I aim to make explicit the actualisation of heritage, following this orienting question: how do human beings come to qualify a thing, be it tangible or intangible, as heritage? I argue that heritage is at the same time a quality allocated by human beings in their relation with things and a fiction that circulates between and anchors in situation(s). To support this assertion, I focus on one element of official heritage, namely houses in the medina of Fez in Morocco, a World Heritage site listed in 1981. <p>Firstly, I follow medina houses in terms of networks, that is to say the various ways to engage with their materiality in the everyday life. In this ethnographic report, I wonder how to inhabit houses located in a World Heritage site. This ethnography allows to question notions such as legality, taste, privacy, hospitality tradition or agency, and it brings to the fore a debate concerning the skills of Moroccan inhabitants to take care of their house and their blindness to heritage. I argue that houses have another story the official heritage one because they offer holds, affordances, to which human actors qualify. Heritage is one of these qualities. <p>I then focus on heritage as a trajectory to shed light on how houses cross the heritage border – are qualified as heritage. I firstly add the category of autodidact experts and I propose a wider definition of expertise as an ability "to speak in the name of". I then underline the importance of senses and affects in the relation with houses and I suggest that they are one possible component in the heritage qualification together with actions and justification. Finally, I argue that better than the notion of heritage border, the notion of attachment allows grasping the qualification of houses as heritage for it stresses both the similarities and the differences between houses and elements of heritage. Heritage as a quality results from a "plus of attention" and relates to nostalgia or a feeling of threat, loss and disappearing; values related to purity, materiality and time; and actions of preservation and transmission. <p>Finally, houses may be heritage through their qualification but heritage is also something else than houses in Fez, such as a label or a justification for members of institution in charge of tourism development or heritage preservation, a tool for sustainable development in the context of international projects, a definition assorted with criteria, an object to preserve for experts, an object of research in the field of social sciences, or a legal object. These are forms of heritage circulating between situations in which they anchor and are actualised. Each form has its own characteristics, its own criteria of (e)valuation, while all the forms share similarities that I define as the heritage fiction, namely a specific relation to the past, the idea of culture as a specific entity, the importance of experts, and moral principles. In a last time, I take as a basis the circulation and the anchorage of the heritage fiction and its forms to think of the local and the global as qualities and not as scales or levels. <p><p>Mon objectif est d'expliciter l'actualisation du patrimoine en décrivant la manière dont les individus qualifient une chose, dans ce cas les maisons de la médina de Fès au Maroc (site du patrimoine mondial depuis 1981), de patrimoine. Dans ce cadre, je définis le patrimoine à la fois comme une qualité que les individus attribuent à cette chose dans leur relation avec elle, et comme une fiction qui circule entre et s'ancre en situation(s). <p>Tout d'abord, je m'intéresse aux réseaux qui passent par et se croisent dans les maisons et je pose la question de l'engagement des individus avec la matérialité des maisons. Cette ethnographie de l'habitat quotidien dans un site du patrimoine mondial permet d'aborder des notions telles la légalité, le goût, l'intimité, l'hospitalité, la tradition ou l'agency. Elle met également en avant un débat sur les compétences des habitants à prendre soin de leur maison et sur leur aveuglement au patrimoine. Je défends l'idée que les maisons ont une autre histoire que celle, officielle, du patrimoine national et mondial et qu'elles proposent aux individus des prises et affordances que ces derniers peuvent qualifier. Le patrimoine est une de ces qualités. <p>Une étude de la trajectoire du patrimoine permet alors d'expliciter comment les maisons traversent la frontière patrimoniale (sont qualifiées de patrimoine). Tout en proposant une définition plus large de l'expertise comme la capacité de "parler au nom de", je relative l'opposition entre experts et non-experts avec la catégorie intermédiaire d'amateur. Je souligne également l'importance des sens et des affects dans la relation aux maisons qui, tout comme les actions et les justifications, constituent des composantes possibles de la qualification patrimoniale. Enfin, la notion d'attachement, mieux que celle de frontière patrimoniale, met en lumière à la fois ce qui est similaire et ce qui distingue les maisons et les éléments de patrimoine. Le patrimoine est une qualité qui résulte d'un "plus d'attention" relatifs à de la nostalgie ou un sentiment de perte, de menace ou de disparition; des valeurs de pureté, matérielles et temporelles; et des actions de préservation et de transmission. <p>Finalement, le patrimoine est aussi autre chose que des maisons à Fès, comme un objet à préserver, un objet légal, un objet de recherche pour les universitaires, un label servant de justification ou d'accroche promotionnelle de la ville, un outil dans le cadre du développement durable, une définition assortie de critères. Ces multiples patrimoines sont autant de formes de la "fiction patrimoniale" qui circulent entre et s'ancrent en situation(s). Si chacune possède ses caractéristiques et critères d'évaluation, toutes partagent les caractéristiques de la fiction patrimoniale, à savoir un rapport spécifique au temps, l'importance des experts, des principes moraux et une idée de la culture comme entité particulière. Je me base sur la circulation et l'ancrage de la fiction et de ses formes pour penser le local et le global comme des qualités d'une chose et non comme des niveaux ou des échelles. <p> / Doctorat en Sciences politiques et sociales / info:eu-repo/semantics/nonPublished

Kompaktní formy bydlení / Compact Forms of Housing

Májek, Jan Unknown Date (has links)
"The compact forms of housing" is a term with which the Czech interior design yet do not often occur. This concept densely built low-rise residential files yet carries a strong potential not only in matters of mere living, but also offers one of the progressive alternative ways of living environment in general. Examined form of residential buildings is becoming increasingly important especially in specific situations where conventional housing is failing and instead generates other social problems. This thesis is primarily seeking the maximum extent available to document the issue of a compact housing, describe its basic form and point out the historical roots of this typology. The acquired knowledge was then subjected to an in-depth analysis, the output of which is to be the most comprehensive characterization researched the topic and its inclusion in the context of the standard forms of housing. The result is a set of research information, assumptions and typological bases that determine the primary urban, architectural, or social limits of the residential category. This work attempts to take into account the specified topic in the broader context of housing as a basic human need. As a result of findings would be its contribution to the culture scene in our home and create a theoretical material that would become an essential information base for creating compact residential files. The conclusions of this research can be further developed, tested and refined in the educational process at the faculties of architecture or in the practice. The results of research could stimulate interest in this type of housing and contribute to the enrichment of Czech housing scene of a synthetic form, which will form the connecting link between the typological family house and an apartment building. Low-rise housing complexes with a high population density can also create an effective counterbalance to the typical suburban development of part-time family home and offer method, respectively one of the alternative ways to be with this dilapidated urban housing estate deal.
