本研究以美國早期的都市社會學與社會心理學的理論，瞭解都市化對都市生活影響的一些表徵，包括大量的人口、差異化的個體、高人口密度，以及有別於鄉村的都市生活面貌，例如冷淡、拘謹、膚淺、利益導向、理性的社會情境等。由於台灣快速都市化讓社會整體進步與發達，但都市的意象不免讓人感到冷漠、疏離與隔離，此是否誠如過去西方的都市社會研究結果一般，源於都市空間會影響都市人的心理與外顯的生活方式，此引發本研究進一步探究之動機。有鑑於過去以都市空間規劃為研究主軸之文獻，顯少有學者直接將「生活方式」與「都市空間」兩大議題做關聯性的探討，而台灣早期60、70年代的都市社會學者，曾以社區凝聚、社區發展、社區意識或是鄰里關係進行討論，但時至今日此類的研究亦顯得零星且分散。因此，本研究關懷都市空間與都市人的議題，以西方文獻中的實證經驗來觀察台灣都市社會的情況，並予以驗證假設一：都市人的空間使用行為會因不同社經背景而有差異；假設二：移入都市生活的居民其自身價值觀將會有所改變；假設三：價值觀的改變會對生活方式與使用都市空間的行為產生影響；假設四：都市人的生活方式會對空間使用產生影響，並與空間課題的產生有所關聯；假設五：都市空間與生活方式有所關聯。 因此，本研究在文獻回顧與推演台灣都市社會的情境後，抽樣台北市大安及士林兩區的居民，瞭解遷移者在價值觀、生活方式與空間使用的情況，並以敘述性統計分析與結構方程模式(SEM)歸納問卷結果，回應研究假設，並驗證都市空間與生活方式之關聯。最後，參照實證結果研擬重塑都市空間新風貌之目標與對策體系，做為提昇都市空間品質的建議；而此建議亦可供政府與規劃單位及後續研究者在政策操作上與研究時之參考。最後，獲致以下幾點結論： 一、本研究認為遷移者進入都市生活後，其價值觀可能被改變或是強化的面向，包括自我防衛、個人主義、經濟報酬、理性、容忍五大價值觀。而生活達一定時間後，生活方式將會受到都市環境的影響，以致呈現較互不干涉(疏離)、社區意識缺乏、務實生活(精確計算)，以及重娛樂休閒的傾向。 二、本研究提出都市空間諸多課題，例如社區空間意識衰頹、公共空間私有化、人行空間被遺忘、消費空間主導地方空間的興衰、人工空間取代生態空間，以及空間的過度與不當利用，可能與都市人被強化或改變後的價值觀與生活方式息息相關。而經由敘述性統計分析及SEM的分析，已驗證本研究所提出之五大假設。 三、本研究認為都市空間是自變數亦是應變數。因此，經由實質與非實質規劃策略之研擬，將可重塑都市空間的面貌，並經由影響生活方式來發掘與提高都市社會互動和社會資本的發展，從而再次影響都市人使用空間的行為與態度。本研究研擬實質空間規劃策略，分成三大目標、三項標的與六大對策--提供適當合宜的公共空間、營造巷弄的春天、提高都市空間水平流動性、形塑友善人行空間的元素、增加非機動車的通行空間、經營都市的精耕主義。同時亦認為，都市人的生活方式亦應搭配做一調整(此屬非實質的規劃策略)，例如建立具有社區鄰里道德規範與共識之生活方式、提高民眾參與度之生活方式、推廣植栽與綠化生活方式，或是推展永續的旅行行為，亦即步行生活方式。 / Based on theories of urban sociology and social psychology, this study explores the effects of urbanization on the urban life, including large population, heterogeneous, and high density. The differences of life style features between country and urban areas are discussed, such as indifferent, reserved, superficial, self-interest, and intellectuality and so on. With the rapid urbanization in Taiwan, society has been entirely improving and developing. However, the image of urban area makes people feel indifferent and segregation. Whether this result is the same as which of the studies found in western society brings me to conduct this study. According to literature review, there lacks scholars directly putting “lifestyle” and “urban space” into a relative discussion. The urban sociologists in 60s and 70s in Taiwan had discussed about community coherence, development, consciousness or neighborhood relationship, while to now this kind of research becomes fragmentary. Hence, this study concerns with issues between the urban space and urban residents. With the western literature review, this study observes the conditions of urban society in Taiwan and proposes the following hypotheses. First of all, the behavior of urban residents who utilize the space will be different due to the social economic status. Second, the self-value will be changed after the residents move to urban areas. Third, the change of value system will influence lifestyle and the utilization of urban space. Forth, the lifestyle of urban residents will affect the way of using urban space. Fifth, there is a connection between urban space and lifestyle. This study conducts a survey in Daan and Shilin districts to explore the value system, lifestyle, and the way of using urban space of immigrants. It employs statistic analysis and SEM to generalize the result of questionnaires in order to verify the above hypotheses and the connection between urban space and lifestyle. Then, based on the outcome of verification, this study suggests several strategies for reshaping the image and functions of urban space. Consequently, this study provides conclusions as follows. 一、The value system of immigrants, such as self-protection, egoism, economic reward, rationality, and toleration will be changed or intensified after people move into urban areas. The lifestyle, however, will be influenced by urban environment after a certain time of living in urban areas. And the characteristics of lifestyle include the sense of aloofness, the lack of community consciousness, material life, and the tendency of focusing on entertainment. 二、According to the SEM analysis, this study has verified the five hypotheses. This study also infers that the degenerative consciousness of community, the personalization for public space, the pedestrian space into oblivion, the wax and wane of regional space led by consumption space, artificial space replacing ecologic space, and the overuse and misuse of space are all relevant to the change of value system and lifestyle of urban residents. 三、This study develops several strategies for reshaping the image of urban space which may further influence urban residents’ lifestyle, attitude, and behaviors toward space utilization and urban environment. In order to create a livable urban space, this study suggests relevant strategies, such as providing decent public space, improving the accessibility of urban space, ameliorating friendly pedestrian space, increasing the walking space, and embellishing urban space through new urbanism.

Diese Dissertation diskutiert am Beispiel der symbolischen Kämpfe zwischen kürzlich Zugezogenen und den Resten alteingesessener subkultureller Gruppen im Berliner Stadtteil Prenzlauer Berg die Frage, welche Rolle Orte bei der Konstruktion räumlicher und sozialer Identitäten spielen und entlang welcher Grenzziehungen diese Identifikationen organisiert werden. Empirisch stützt sich die Arbeit auf Tiefeninterviews mit den oben genannten Gruppen und einer Mediendiskursanalyse zum umstrittenen Symbol „Prenzlauer Berg“. Soziale Identität, das simultane Wechselspiel interner Identifikation und externer Kategorisierung (Jenkins 1996), ist eng verbunden mit der Frage nach Zugehörigkeit. Das Konzept des elective belonging (Savage et al. 2005) zeigt die Verbindung von Lebensstil und Wohnort. Diese Arbeit weist darüber hinaus auf den Zusammenhang zwischen einer starken symbolischen und praktischen Nachbarschaftsnutzung (Blokland 2011) der Zugezogenen und deren hoher Ortsidentifikation hin. Die eingesessene Subkultur Prenzlauer Bergs interpretiert diese symbolische Nutzung als einen Angriff auf die alte Ordnung im Kiez und bezieht ihre Verbindung mit dem Ort, infolge der fundamentalen Wandlungsprozesse, aus dem Erinnern (Halbwachs 1991) an eine Zeit, in der sie selbst sich den Raum aneigneten. Damit stellen sie der neuen Bedeutung Prenzlauer Bergs eine frühere Bedeutung, d.h. eine spezifische Vorstellung räumlicher Normalität, entgegen. Ausdruck dieser konkurrierenden Definitionen von Zugehörigkeit sind symbolische Grenzziehungen (Lamont; Molnár 2002) gegenüber neuen Bewohner_innen, die sich auch im medialen Diskurs über den Prenzlauer Berg wiederfinden. Dabei wird klar, dass die subkulturellen Stimmen zwar die Definition von Zugehörigkeit dominieren, der identifikatorische Zugriff auf die Nachbarschaft aber nur noch selektiv gelingt. Demgegenüber müssen die kürzlich Zugezogenen stetig um die Legitimation ihrer Zugehörigkeit kämpfen. / This thesis explores the role of place within constructions of social and spatial identities, and symbolic boundary work using the case of existing subcultural groups and affluent newcomers in the Berlin district of Prenzlauer Berg. Empirically, this work draws on in-depth-interviews with both groups as well as a media discourse analysis of the contested meanings of the symbol ‘Prenzlauer Berg’. Social identity, understood as the simultaneous interplay of internal identification and external categorization (Jenkins 1996) is strongly related to a sense of belonging. While the concept of elective belonging (Savage et al. 2005) shows a connection between lifestyle and neighbourhood, this thesis also points to the strong relationship between symbolic and practical neighbourhood use (Blokland 2011), and place identification of newcomers. Subcultural groups read the newcomers’ symbolic neighbourhood use as an attack on the old order of the “Kiez”. Due to substantial neighbourhood change, these subcultures draw on remembering times (Halbwachs 1991) when their neighbourhood use was strong, both symbolically and practically. In this process, an old meaning of the neighbourhood (i.e. a specific notion of what the place used to be) is constructed in contrast to new meanings. These constructions are expressed in symbolic boundary work (Lamont; Molnár 2002) towards newcomers, a process which powerfully connects to media discourse. It becomes clear, then, that although a definition of belonging is dominated by the subculture, their access to the neighbourhood in terms of identification is only selective. In contrast, newcomers have to constantly defend their legitimacy to belong.

Diese Dissertation forscht in der Philosophie und in der Theorie des Sozialraumes, und kommt zu einer theoretischen Betrachtung des Sozialraumes, die helfen kann, Sozialprozesse in Berlin zu erklären. Bezug nehmend auf Lefebvres, Theorien der Unterschiedlichkeit und der Vielfältigkeit wird spatialisiert. Im Gegenzug werden anhand von Theorien, der Unterschiedlichkeit und Vielfältigkeit, die auf transnationalem Urbanismus, und der feministischen Geographie basieren, die Grenzen der lefebvreschen Theorie des Sozialunterschiedes herausgestellt. Während die Theorien von Lefebvre schwerpunktmäßig auf Marx basieren, basieren die feministischen poststructural Theorien des Unterschiedes in der Darlegung auf endloser Flexibilität, Zerteilung und radikaler Vielfältigkeit. Es gibt folglich eine unüberwindbare Kluft zwei theoretischen Perspektiven. Um die Beschränkungen und die Möglichkeiten dieser Perspektiven zu veranschaulichen, werden zwei soziale Phänomene beschrieben Das erste ist die Entwickelung der Hausbesetzerszene in Berlin nach dem Mauerfall. Das zweite sind die Erfahrungen, der Newcomers in Berlin. Einige Grenzen der Hausbesetzer und der Newcomers werden durch die Anwendung der Theorien des produzierten Raumes von Lefebvre, der flexiblen Vielfältigkeit von Doreen Massey, der übernationalen feministischen Geographie von Geraldine Pratt, und der radikalen Flexibilität und Fragmentation von Zygmunt Bauman deutlich. Die Geographie der Hausbesetzerbewegungs- und die Geschichte der Newcomers decken nicht nur einen Mangel an Zentralität, sondern auch ein umfangreiches überterritoriales Netz auf. Sie zeigen auch, dass Unterschiedlichkeit sich im Raum materialisiert. Eine Brücke zwischen Lefebvre und poststruktureller Unterschiedlichkeit konnte durch das Überdenken der für Lefebvre notwendigen Zentralität des Sozialraumes, so wie des ökonomische Reduktionismus gefunden werden. Gleichzeitig, kann der Diskurs der Unterschiedlichkeit einen Nutzen aus einer tieferen Analyse der materiellen Form des Raumes. Diese Abhandlung ist folglich ein Zugang zum allgemeinen Überdenken der räumlichen Sozialtheorie. / This ideational dissertation delves into the philosophy and theory of social space, and arrives at a theoretical vision of social space which can help explain social processes in Berlin. Drawing on Lefebvre, theories of difference and multiplicity are spatialised. Conversely, drawing on theories of difference and multiplicity from transnational urbanism and feminist geography, the limits of Lefebvre’s theory of social difference are exposed. While the theories of Lefebvre are heavily based on Marx, the feminist poststructural theories of difference are based in the discourse on infinite flexibility, fragmentation, and radical multiplicity. There is thus a gaping cleft between the two theoretical perspectives. To illustrate the limitations and possibilities of these perspectives, two social phenomena are described. The first involves the post-Wall squatter scene in Berlin. The second involves experiences of newcomers in Berlin. By examining the theory of produced space from Lefebvre, the theories of coeval and flexible multiplicity from Doreen Massey, the theories transnational feminist geographies of Geraldine Pratt, and the imagery of flexible everything from Zygmunt Bauman, some theoretical borders of squatters and newcomers come into focus. The geographies of squatter movements and newcomers’ history reveal not only a profound lack of centrality, rather an extensive trans-territorial network. They also show that difference is deeply spatialised and material. A bridge between Lefebvre and poststructuralist difference might be found in the rethinking Lefebvre’s necessary centrality of social space, as the economic reductionism his Marxism requires. At the same time, the discourse on difference might benefit from a deeper analysis of the materiality of space. This dissertation is therefore an entry point into the general rethinking of social space.

In settings such as hotels, bars and boutiques, things like cars, sodas, clothes, and cities, are fueled with the symbolic capital of graffiti. The purpose of this ethnographic study is to understand how graffiti writers, through marketing, increase the value of their work, as well as that of other products, and how this commercialization affects the meaning of graffiti.  Utilizing a perspective of social constructionism, the analysis shows how actors and social fields that are constructed as incongruous (e.g., art galleries and graffiti culture), are at the same time being mixed together to create something new, and thus create value. This study shows how practices that are considered marginal, or deviant, at the same time generate value within the general economy. Deploying an abductive approach, and building on ample empirical material, this study shows that the narrative of graffiti as something illegal is one of the main traits that enables graffiti writers to exchange subcultural capital for economic. The results show that previous research, investigating graffiti from a dichotomous perspective of either art or vandalism, do not give a satisfactory understanding of this diverse subculture.   The empirical material consists of 30 participant observations in public events, in Sweden during the autumn of 2014, where graffiti is turned into a commodity embodied with subcultural capital. Moreover, four in-depth interviews were executed with graffiti writers who have sold their competence and art for purposes of marketing, and one group interview with three of their customers. Further, several documents were collected and analyzed.

This PhD study is at the intersection of people, place and technology and pioneers innovative development approaches towards interactive social networking systems informed by community, social and urban studies and employs human-centred and participatory design methods. The project delivers a greater understanding of the potential for internet-based systems to support and facilitate social networks of urban residents and the role of those networks to foster neighbourhood identity and social capital. Departing from conventional notions that regard communities as collectives, this study builds upon more contemporary interpretations of community inherent in Castells’ and Wellman’s theories of the network society and networked individualism. The thesis challenges the view that a mere re-appropriation of applications used to support dispersed virtual communities of interest is adequate to meet the place and proximity-based design requirements that community networks in urban neighbourhoods pose. The overarching principal research aim of the study is to propose new ways of conceptualising the roles of social networks of urban residents to better inform the design of new technology facilitating urban neighbourhood developments. Addressing this aim requires a new understanding of the roles of social networks of urban residents. The study sets out to critique the implicit theories underlying technology design in this area and to propose a more appropriate theory based on recent developments in the field and empirical findings from the study. The key research questions are: 1. What theoretical model can better represent social interaction of residents in inner-city apartment buildings? 2. How can relevant research methods be adapted to take the network qualities of social interactions into account? 3. What are the implications of a new understanding of social networks for the design of technology that supports the growth of neighbourhoods? 4. What are the implications of a new understanding of social networks for an urban architecture that supports the growth of neighbourhoods? Within a framework of action research, the study follows a case study approach of three different inner-city residential apartment complexes in Brisbane. Research methods are mostly qualitative and ethnographic and include surveys, focus groups, participant observation and interviews, as well as participatory design. The study delivers innovative outcomes on three levels: 1. Theoretical innovation with an analytical translation of Wellman’s notion of networked individualism and a conceptualisation of the communicative ecology model into the context of system design that supports social networks of residents in inner-city apartment buildings; 2. Methodological innovation with the presentation of Network Action Research, an addition to the action research family which pays particular attention to the network quality of social formations in communities; 3. Empirical innovation with research findings which indicate that the key factors influencing the successful design and uptake of interactive systems to support social networks in urban neighbourhoods. They include the swarming social behaviour of urban dwellers, the dynamics of their existing communicative ecology, and the serendipitous, voluntary and place-based quality of interaction between residents on the basis of choice, like-mindedness, mutual interest and support needs. Findings are presented in three parts to audiences interested in people, technology and place. Drawing on social, urban and computer sciences, this research project delivers insights which will assist efforts to facilitate urban neighbourhood community building with new media and network ICTs. Understanding the issues and challenges as well as opportunities and strengths in forming a local meshwork of social networks will help Australians negotiate the complex web of daily choices, access a greater social safety net, and participate in the socio-cultural and socio-economic life of their city. This in turn will contribute to greater social inclusion, urban sustainability and healthier local economies.

Por meio de uma abordagem que busca ir além das determinantes estrututrais de organização e formação do território metropolitano, o trabalho procura apontar os sentidos contidos nas trajetórias urbanas inscritas nos projetos migratórios dos próprios bolivianos. O trabalho utiliza, entre outras fontes, dados quantitativos (Censo 2000, registro de bolivianos no Sistema Único de Saúde) e qualitativos (entrevistas semidigiridas e observação de campo), sendo estruturado em três dimensões de análise. A primera é uma breve descrição do contexto das migrações na Bolívia, para situar as origens dos movimentos migratórios para o Brasil, desde os anos 1950. Focamos El Alto (departamento de La Paz), com base na hipótese de que o maior contingente populacional da migração boliviana à RMSP, a partir dos anos 1980, é oriundo desta cidade. A segunda dimensão consiste em apresentar a localização dos bolivianos na escala metropolitana, privilegiando alguns pontos de sua agregação. A terceira, enfim, contempla a escala microssocial, analisando as trajetórias urbanas dos bolivianos neste espaço e, entendendo o mesmo como recurso, busca acompanhar seu uso por estes migrantes / Abstract: This research aims to understand the socioterritorial insertion of Bolivian migrants in São Paulo Metropolitan Region (RMSP). Through an analysis that goes beyond the structural determinants of organization and formation of São Paulo's metropolitan territory, the dissertation focus the urban trajectories inserted in the migratory projects of the migrants themselves. Among others sources, the work uses quantitative data (2000 Census, data from the register of Bolivians in the Unified National Health System) and qualitative (semistructured interviews and field work), to present three dimensions of analysis. The first is a brief description of the migratory context in Bolivia, to point out the origins of the migratory movements to Brazil, since 1950's. We focus on the city of El Alto (La Paz's department), based on the the hypothesis of that the most part of of the Bolivian migration to the RMSP, since the 1980's, is derived from this city. The second dimension presents the Bolivians location at the Metropolitan scale, focusing some of its aggregation points. The third, contemplates the microssocial scale, analyzing the urban trajectories of the Bolivians in this territory and, taking it as a resource, aims to understand its appropriation by the migrants / Mestrado / Mestre em Demografia

O projeto da casa popular ou ¿habitação social¿ apresenta uma arquitetura padrão e fechada que não leva em consideração as necessidades individuais das famílias moradoras, gerando frustrações com relação ao produto final. Os futuros moradores, excluídos da fase de elaboração do desenho de suas casas, acabam encarando uma segunda luta pela moradia adequada: a adaptação da casa padrão de forma a transformá-la em uma moradia que realmente atenda às necessidades de sua família. No entanto, o processo de transformação das casas populares passa a ser uma batalha individual para essas famílias, sem o apoio do Estado. O presente trabalho analisa o processo de planejamento, negociação, construção e transformação de casas populares em um Projeto Habitacional brasileiro, destacando a participação das famílias mutirantes ¿ futuros moradores ¿ nesses processos. Utiliza-se o referencial teórico do Construtivismo Social da Tecnologia, com destaque para as relações entre gêneros. Desta forma, alguns aspectos foram observados, como: os grupos sociais relevantes, os conflitos de interesses entre os grupos, a influência dos moradores no processo de decisão e implementação dos acordos entre grupos, fechamento das situações de conflito, além da participação das mulheres na construção física e social das casas populares. A análise se baseia, principalmente, na observação direta da atuação do grupo de moradores e representantes da Prefeitura durante reuniões para discussão dos rumos do Projeto Habitacional no bairro Jardim dos Lírios, em Americana/SP. Algumas entrevistas com os principais atores envolvidos no caso estudado contribuíram para o desenvolvimento da pesquisa. A organização dos futuros moradores ¿ em especial das mulheres ¿ com o objetivo de criar estratégias para influenciar o processo de desenvolvimento do artefato, conquistando alterações no desenho inicial das casas tem-se mostrado um grande avanço na busca por projetos habitacionais mais participativos e democráticos / Abstract: Although the Brazilian housing programs presents some facilities to low-income families, they tend to exclude future residents from the participation in the decision-making process about their own houses. The ¿social housing¿ project presents a standard and closed design, which does not take into consideration the residents¿ needs and life styles.The tenants, after receiving the standard houses, have to struggle again, by rebuilding and transforming the received units, in order to achieve what they consider as adequate housing. At this stage, however, the process of transformation of the popular houses becomes an individual battle for these families, without State support. The present work analyzes the process of planning, negotiation, construction and transformation of popular houses in a Brazilian Housing Project, with a special focus on the participation of the future residents in these processes. The research is undertaken in line with the framework of the social construction of technology (SCOT). As such, it is concerned with the social process of building of popular houses in a Brazilian Housing Project, identifying all relevant social groups involved, their interests and views about the final artefact (the house unit), as well as their strategies to shape the artefact. The analysis has also identified situations of conflict among social actors, negotiation processes and agreements reached. Special attention was given to the women¿s role in the whole process. The analysis is based, mainly, on direct observation of the performance of the participants during the meetings between the group of future residents and representatives of the City Hall. Interviews with key actors in the housing project contributed to the development of the research. The organization of the group of residents - in special of the women - to influence the construction process and to search alterations in the initial design of the house has proved to be a new and successful route to more participative and democratic housing projects / Mestrado / Mestre em Política Científica e Tecnológica

A partir d’une ethnographie de la mobilité des travailleurs colombiens originaires de classes moyennes urbaines, cette recherche explore les recompositions spatiales, sociales et d’entraide, à la lumière d’une mondialisation qui prône la flexibilité tout en limitant la mobilité de certains. Les Colombiens font parti du groupe des indésirables au niveau de la mobilité internationale et passent par des formes de contournement et de dénationalisation; mais ils sont bien placés au sein de l’échelle des migrants aux Etats-Unis où ils reconstruisent des identités positives. Cette approche contribue aux études sur les latinos aux Etats-Unis en y positionnant le groupe des Colombiens qui bien que numériquement important est aujourd’hui invisible, mais aussi au débat sur le rôle des réseaux sociaux dans les mobilités. Ces migrants n’utilisent les réseaux d’origine nationale que comme une aide parmi d’autres et la méfiance joue un rôle récurrent dans les liens qu’ils développent. L’approche multi sites incluant le pays d’origine a permis de mieux interpréter les stratégies des personnes qui se construisent au sein d’un seul champ social. L’étude rend compte de la remise en question des hiérarchies et du rôle des femmes au sein des relations transnationales. Enfin, ce travail questionne la fonction de la ville globale et des quartiers multi ethniques non ségrégués dans l’accueil des migrants. En effet, loin des schémas des quartiers ethniques isolés, les Colombiens ont construit différents «espaces colombiens» dont Jackson Heights, dans le Queens, serait un nœud essentiel leur donnant accès à un capital social au niveau du «Grand New York», mais aussi de certains réseaux transnationaux. / Based on the ethnography of the mobility of middle-class Colombian workers of urban origin, this research explores the spatial, social and solidarity reconstructions, amidst a globalization process which advocates for flexibility while restricting the mobility of certain individuals. Colombians belong to an undesirable group when it comes to international mobility and they go through certain forms of bypassing and citizenship denial; however they are well positioned when it comes to the social standing of migrants in the United States, finding ways to recreate positive identities. This approach contributes to the studies about Latinos in the United States, not only placing Colombians within this group, currently invisible in spite of their growing number, but also placing them in the debate of the roll of social networks in mobilities. These migrants only use the national origin networks as an aid among others and distrust plays a recurrent roll in the connections they develop. The multi city approach, including the country of origin, has allowed a better interpretation of the strategies of persons who grow in a unique social field. This study brings back the question of hierarchy and of the roll of women in transnational relationships. Finally, this study questions the function of the global city and of non segregated multi-ethnical neighbourhoods concerning the reception of migrants. In fact, far from the schemes of isolated ethnic neighbourhoods, Colombians have built different «Colombian spaces», Jackson Heights in Queens being an essential knot giving them access to a social capital, not only at a «Great New York» level, but also to certain transnational networks.

Aujourd’hui, le terme de logement social est généralement associé en France à l’activité de construction et de gestion locative réalisée par les organismes HLM. Depuis l’invention des Habitations à Bon Marché à la fin du 19ème siècle, le contenu de cette catégorie n’a cependant cessé d’évoluer. La diversité des acteurs qui sont à l’origine de l’émergence du logement social et la multiplicité des causes qu’ils défendent ont été étudiées par les travaux portant sur les « réformateurs sociaux » au tournant du 20ème siècle. Mais ces questions sont peu traitées par les recherches historiques et sociologiques qui portent sur le mouvement HLM depuis les années 1950. Cette thèse entend donc examiner la recomposition des frontières du secteur du logement social depuis cette date en se penchant sur la diversité interne du mouvement HLM et sur les rapports de force qui le traversent. Pour cela, elle prend pour objet principal des acteurs minoritaires parmi les élites dirigeantes de ce mouvement : les promoteurs et spécialistes de l’accession dite « sociale » à la propriété. Elle analyse les processus qui rendent cette activité plus ou moins légitime selon les périodes, qui font évoluer son cadre juridique, et modifient les pratiques économiques auxquelles renvoie ce terme. A partir d’un travail réalisé à partir de sources écrites (dépouillement d’archives publiques et de publications du mouvement HLM), d’une enquête de terrain menée auprès de responsables nationaux de fédérations professionnelles ainsi que de dirigeants d’organismes, complétée par des sources statistiques, cette thèse cherche ainsi à rompre avec une vision homogénéisante du secteur du logement social, comme institution et groupe d’acteurs aux intérêts et aux positions unifiées. / Social housing is a term usually associated in France with the building and the management of rental housing by the organisations of « Habitations à Loyer modéré » in France. However, since the creation of these institutions at the end of the 19th century, the meaning of the term « social housing » as kept evolving. The diversity of the actors who contributed to the institutionnalisation of a social housing sector, and of their discording views on the form it shoud take, has been thoroughly studied by research on social reformers at the turn of the 20th century. By contrast, these questions have been little studied by sociological or historical research on social housing since the 1950’s. This research aims at analyzing how the frontiers of the social housing sector have evolved since then, taking into account the inner diversity of the HLM movement, and the power struggles which characterizes this institution. To that purpose, it focuses on a specific category of actors, which hold a minority situation in the HLM movement, the promoters of « social » home-ownership. It analyzes the processes through which this specific activity gains or loses legitimacy in this institution, the evolution of its legal framework and of its economic content. Relying on a the study of public archives, on a fieldwork conducted on the political and economic elites of the HLM movement, and on the use of statistical data, this research aims at breaking with the homogeneous image which is often given of this institution, too often seen as a unified interest group.
