Pour une approche urbanistique de la conservation et de la mise en valeur du patrimoine bâti : l’expérience du canal de Lachine à Montréal

Thèse réalisée dans le cadre d'une cotutelle avec l'Université Paul Cézanne Aix-Marseille III

Les pratiques des usagers dans les friches urbaines végétalisées et leurs facteurs d’influence : analyse de deux cas montréalais.

Dans l’ère post-industrielle, où la densification apparaît comme une solution afin de freiner l’étalement urbain, la question de l’avenir des terrains en friche devient incontournable. En effet, ceux-ci deviennent hautement convoités par les acteurs du redéveloppement urbain puisqu’ils détiennent un potentiel foncier important. Face à ces pressions, cette recherche s’intéresse à la complexité des terrains en friche, puisqu’il existe une diversité de potentiels, outre le foncier. Parmi ces potentiels, les friches peuvent être utilisées comme des espaces verts urbains. Effectivement, il arrive qu’on retrouve sur ces sites des usagers qui les fréquentent, à différents desseins. L’étude tente ainsi de répertorier et de comprendre les pratiques faites par les usagers, pour deux cas étudiés à Montréal : le Boisé Jean-Milot et le Champ des possibles. L’objectif est non seulement de qualifier ces pratiques, mais également de mettre en évidence les facteurs d’influence qui les sous-tendent. La recherche s’inscrit dans les approches personnes-environnement. D’un point de vue méthodologique, des entretiens in situ ont été menés avec les usagers afin qu’ils puissent expliquer leur expérience vécue de la friche. Les facteurs d’influence ont émergé des discours tenus en entrevue. Les cas étudiés montrent que la friche est un espace d’exception en ville : les friches urbaines végétalisées sont le cadre de pratiques exclusives, en plus de faire vivre une variété d’ambiances à l’usager. Les résultats permettent ainsi de placer la friche comme un espace vert complémentaire au parc urbain. La friche fait partie d’un portfolio d’espaces disponibles, utilisés au moment présent. En relevant les facteurs qui influencent les usagers à fréquenter les friches, on met en lumière des qualités qui pourraient être utiles dans la planification des espaces verts urbains et dans le développement d’une vision innovante pour l’avenir des friches.

Auto-reflexividad, erografía y leitmotivs liminales en la producción narrativa de Mayra Santos-Febres (1995-2009)

La recherche, construction et révision de l’identité nationale ont très longtemps constitué les éléments propulseurs de la production littéraire et intellectuelle de Porto Rico. Pourtant vers le milieu des années 90, un nouveau consensus émerge entre les écrivains qui revendiquent massivement la fin de la littérature en tant que lieu d’où forger la conscience nationale et refuse le leadership intellectuel qui avait jusqu’alors définit le travail littéraire. Les auteurs qui commencent à se manifester à ce moment se désintéressent du nationalisme comme thème littéraire. Le militantisme politique et la volonté de confrontation, modes représentationnels caractéristiques de la génération antérieure, disparaissent pour laisser place à une écriture exploratoire, centrée sur ses propres procédés, et apparemment apolitique. Une telle perte d’ancrages nationaux et territoriaux est significative de la conscience exacerbée que possèdent ces écrivains de la complexité des dynamiques culturelles qui régissent le monde postmoderne et globalisé, ainsi que de la « valeur » et de la position « marginale » qu’on leur attribue dans l’écologie mass-médiatique culturelle actuelle. La production narrative de Mayra Santos-Febres est paradigmatique de ces changements. J’aborde dans son écriture une série de dispositifs métalittéraires, autoréflexifs, « érographiques », et historiographiques qui, bien qu’ils résistent à une catégorisation homogène, démontrent un même intérêt pour des phénomènes interstitiels. En me basant sur les concepts de liminalité, principalement depuis la perspective de Victor Turner et d’écriture auto-réflexive (Patricia Waugh, Linda Hutcheon), j’analyse le positionnement liminal qu’assume Santos-Febres dans la structure culturelle globalisée actuelle, et la façon dont sa prise de position, également liminale, c’est-à-dire, sa prise de parole et son engagement se traduisent par un rapprochement narcissique à l’exercice littéraire autant dans les formes qu’elle crée qu’au niveau sémantique, narratif et discursif. Le premier chapitre analyse les contes « Dilcia M. » et « Acto de Fe » (Pez de vidrio) comme témoignages de l’érosion du patriotisme et militantisme antérieur; « La escritora» (Pez de vidrio) qui marque pour l’auteure un passage vers une esthétique centrée sus ses propres procédés créatifs; et le roman Cualquier miércoles soy tuya qui dramatise le positionnement assumé par les écrivains dans la chaine culturelle globalisée actuelle. Le second chapitre aborde la configuration des corps, espaces urbains et de l’écriture dans El cuerpo correcto qui, à travers une exubérance sexuelle/textuelle, projette des variantes réactualisées de la traditionnelle dichotomie corps/écriture. Le troisième chapitre se penche sur la configuration du travesti dans Sirena Selena vestida de pena. J’y propose de voir le travestisme, le boléro et l’écriture comme un triple exercice métalittéraire. Le dernier chapitre aborde le procédé de re-signification littéraire des images sédimentées de subordination et d’infériorité de sujet « noir ». Nuestra Señora de la Noche se penche sur la re-signification de l’hyper-sexualisation et « exotisation » qui a cimenté la construction de « l’immoralité » de la femme noire. Fe en disfraz aborde le sadomasochisme comme espace de re-signification des schèmes de domination et soumission inscrits dans l’histoire esclavagiste de Porto Rico et du trauma qui origine, et subsiste, d’une telle hiérarchie.

Comparación de las dinámicas de uso y apropiación del espacio público en parques de origen informal y formal: parque Villa de la Torre y parque Cayetano Cañizares

El interés de este estudio de caso es comparar las dinámicas de uso y apropiación del espacio público en parques de origen formal e informal, y discutir sus implicaciones en la vida social y urbana, teniendo como zonas el parque Villa de la Torre (informal) y el parque Cayetano Cañizares (formal). Este trabajo se enmarca en conceptos de uso y apropiación del espacio público, a partir de los cuales se examinan las dinámicas de formalidad e informalidad de los parques zonas de estudio, explorando qué efectos puede tener su origen, y revisando si el parque informal implica falta de apropiación y usos conflictivos, o si por el contrario, las dinámicas que en espacios públicos se dan pueden incluir dinámicas positivas y negativas indistintamente de su origen.

El cinema i la constitució d'un públic popular a Barcelona. El cas del Paral·lel

Between 1895 and 1910 Barcelona saw a whole range of social, political and cultural changes due to the increasingly important emergence of the working masses. At the same time, the cinema arrived in Catalonia, becoming very quickly one of the favorite entertainments of the urban laboring population which was about creating a new culture opposed to the modernist and nineteenth-century elite .This is, broadly speaking, the context that serves as a starting point for a study of the role of cinema in shaping a mass audience in Barcelona, an analysis centered on new urban spaces intended for the leisure of the lower classes emerged with the birth of modern Barcelona, especially the “Paral•lel” avenue, whose opening in 1894 made even more apparent the great social tensions and existing inequalities in Barcelona’s society at the end of the century.

A Reabilitação face à Sustentabilidade : Casa Burguesa do Porto

Os centros históricos são o resultado de um parque habitacional corrente, com uma grande uniformidade, coerência construtiva e espaços urbanos de modo a proporcionar uma identidade própria. Um dos grandes problemas urbanos são as vastas áreas degradadas do ponto de vista arquitetónico como também social, cultural e económico. Conhecidos os principais problemas dos edifícios de habitação e suas causas, para sua resolução existe necessidade de adaptar o processo de reabilitação tradicional ao conceito de sustentabilidade. Estes dois assuntos conjugados são atualmente emergentes, devido à necessidade de reabilitação do parque habitacional, nomeadamente centros históricos. A casa burguesa do Porto apresenta um elevado grau de degradação, porém apesar de existentes as ações de intervenção que sobre ela reincidem, não são proporcionais à necessidade atual. A cidade do Porto é marcada, maioritariamente, pelas Casas Burguesas, das quais foram executadas segundo padrões de conforto e de utilização da época. É, então, fundamental um estudo pormenorizado da casa burguesa do Porto, avaliando o contexto em que esta se encere (na cidade e na respetiva habitação), os subsistemas construtivos e as praticas de reabilitação.

Telefantasy tower blocks: space, place and social realism shake-ups in Misfits

This article considers the ways in which British youth telefantasy Misfits (E4, 2009–13) takes up and makes strange urban spaces familiar from social-realist narratives. Filmed on the sprawling East London estate, Thamesmead, the programme chronicles a group of young offenders who are given powers by a freak storm, turning them into ‘ASBO superheroes’. Misfits depends on its British urban landscapes for the assertion of its ‘authenticity’ within British youth television, using spaces and landscapes familiar from urban youth exploitation cinema and television's narratives of the underclass. After situating the series within existing cultural discourses and recent developments in social-realist representations, the article explores how Misfits disrupts what have become signifiers for the ‘real’ – the brutalism of housing estates, the grey of the concrete and sky – by making them strange, turning them into telefantasy. The series presents the estate as an uncanny place: the domestic, social-realist world shifted into a fantastical space by the storm. Through close analysis, this article explores how the familiar spaces become skewed and unsettling to match our protagonists' isolation, shifting bodies and scrambled sense of self.

Planning in the face of ‘deep divisions’: a view from Beirut, Lebanon

This article discusses planning in the global South-East while focusing on the specific context of social divides, political turmoil and conflict situations. The article proposes a five-way framework based on political science and planning to theory to analyse such contexts. The article explores the case of Beirut, Lebanon that has undergone several episodes of internal and external conflicts resulting in a society splintered along sectarianism. Three Two case studies of open urban spaces and their public activities are analysed using the five-way framework The discussion indicates how economic liberalism that is prevalent in countries of the South-East, along with place-based identities, interest-based identities, consensus orientated processes and institutionalism might facilitate a cultivation of deep values away from a narrowly constructed identity. The article argues that planners should understand the options for positive action that aim to bridge deep divisions and suggests that the five-way framework provides a reference for contextualising in different ways to suit particular contexts. Therefore, the framework is not necessarily restricted to the South-East but could be applicable to any context which manifests deep divisions.

Palhaços: poética e política nas ruas: direito à cultura e à cidade

O presente trabalho analisou ações culturais em logradouros públicos do município do Rio de Janeiro, atualmente chamadas de Arte Pública, no contexto posterior a promulgação em junho de 2012 da Lei do Artista de Rua, que garante o uso livre do espaço urbano para as apresentações artísticas destes grupos e artistas e reconhece oficialmente estas manifestações. A partir deste quadro a pesquisa se propõe a refletir sobre as possíveis contradições entre a mediação cultural que acreditamos ser inerente a este segmento e a institucionalização decorrente desta lei. O estudo da mediação visou ainda pensar em outras formas de participação social no planejamento das políticas culturais. A investigação foi feita prioritariamente com palhaços profissionais que atuem nas ruas, praças, comunidades e outras áreas públicas do município.

De repente, tudo mudou de lugar: refletindo sobre metamorfose urbana e gentrificação em Mossoró-RN

This study aims at solidifying the theoretical bases to provide, above all, an explanation for this phenomenon which currently happens, with a scenario of social, political, economic and cultural transformations worldwide in medium cities. Nevertheless, because it has different dimensions from its transformation axes, gentrification comes with change, but also with the introduction of a new purpose in the space using and occupation, outlining in this context the identity of places from the formation of centralities with the presence of flows with social and economic dynamicsThe current forms of geographic space appropriation show the directions of the senses and ideological profile which recreates the meanings and uses of content and materials from descriptions of a historical past. However, today there is an economic context in the urban space which refers to a search of strategies for change, i.e., the acquisition of parameter aimed at meeting the demands of the relationship between capital and labor, which ends up overriding some actions for the specification of the transformation methods within the urban space to be explained by new needs and also by the agents from the value adding to their interests and investments. Thus, we assume that the appreciation/gentrification of urban spaces may or may not result from the building of a public space, since the dialogic structure as a place of political interaction externalize conflicts and disagreements in general; it keeps segregating spaces. As new spaces are transformed, the access to them tends to happen with particular restriction, whereas some places like parks, shopping malls, high-rise and horizontal condos are the scene for major professional and family events. In this context, the gentrification process is used to designate interventions in the urban environment, in certain city spaces which are considered central to public and private investments. A historical place is permitted to be presented as a scenario, a stage full of attractions, through the transformation process. Studying gentrification consists of an analysis of the underlying interests in the transformation of these areas, and especially of the assessment of the interest level in the private sector to partner in order to modify the landscape. Gentrification results from the transformation processes of capital, which influences the efforts and investments application in order to establish and achieve optimal economic growth, focusing on a location socio-culturally centered in the urban space. Thus, the urban social structure develops in the light of some questions that relate not only the cities growth but also environmental conditions it provides in cities like Mossoro, State of Rio Grande do Norte, Brazil 2005 a 2011.

Povoações, freguesias e vilas na Paraíba Colonial: Pombal e Sousa, 1697-1800

The towns presently named Pombal and Sousa, located in the hinterland of the State of Paraíba, Brazil, still keep vestiges of the colonization process they went through along the 18th and 19th centuries, when they both emerged as settlement nuclei in the extreme West of the then captaincy of Paraíba and attained the status of freguesia and vila in a later period. This research aims to comprehend the process of urban formation and development of the colonial urban nuclei of Pombal and Sousa as they became povoados (hamlets), freguesias (parishes) and vilas (small urban communities with a local government), according to territorial expansion policies implemented by the Portuguese government from 1697 to 1800. The choice of the two urban settlements for this survey lies in the fact that they were part of the great conquest and colonization program undertaken by the Portuguese Crown. Another aspect that was considered was the fact that those towns are the oldest urban nuclei of Paraíba s hinterland. They came into being as early as in the times of the colony, thus producing a favorable environment to the study of the changes that occurred in the captaincy s hinterland scenery resulting from the process of formation and development of the colonial urban space. Three fundamental categories of analysis were defined since they have a direct bearing upon the urban configuration of the two colonization nuclei: povoado, freguesia and vila. The three of them are related to civil and ecclesiastic jurisdictions. Field, documentation and bibliography surveys were undertaken in order to develop the study. They allowed for the finding of vestiges of the old, colonial urban structures and for the development of theoretical analysis based on present-day studies of issues relating to the colonial urban history. The study purposes were, therefore, to try to understand how the old urban nuclei of Pombal and Sousa fit in the territorial expansion policies undertaken by the Portuguese government; to relate the process of urban formation and development of such nuclei with the categories of analysis povoação-freguesia-vila by discussing the relations and influences they exert over one another and their territory, as well as to unveil, as much as possible, the configuration the urban spaces that were shaped along the 18th century

Uma cidade para pessoas: funcionalidade, racionalidade e emotividade nas relações mobiliário urbano, espaço público e cidadãos

This research investigates how functionality, rationality, and emotionality applied to urban furniture design contribute to the organization, legibility, and qualification of public spaces, according to different layouts, physical and visual qualities of the urban furniture as well as the quality of urban infrastructure that may influence the uses and appropriation of urban spaces by pedestrians, turning those spaces into socially centripetal or centrifugal places. The work consists of two parts. First refers to a bibliographical review concerning two main issues of the investigation: product design and legibility of public space, defining the conceptual and theoretical bases, linked to methodological strategies aimed at systemic planning and integrated management of urban furniture design and legibility of public spaces (sidewalks), that are necessary to define the existing relationships among the user s interface (pedestrians); product (urban artifacts); built environment (sidewalks). The second part refers to the achievement of empirical approach throughout visual analysis of public spaces and the functional and qualitative evaluation of the existing urban furniture in the central neighborhood of Cidade Alta, Natal, RN, according to the theoretical researched concepts and methodological procedures. The results expose the weaknesses and levels of intensity arising from the relations among public space, urban furniture, and users, revealing the need for theoretical and practical approaches which would help the decision-making in planning, designing and integrating innovative, sustainable, and ethical solutions in order to design attractive public spaces that could provide sociability and citizenship throughout integrated public management, city systemic thinking and urban identity. The suggested guidelines at the end of this research will provide the necessary strategies to design suitable urban furniture systems according to aesthetic and practical urban infrastructure and city context, aiming to ease visual and physical conflicts that may negatively interfere with the appropriation of public spaces by the citizens

O terciário (re) desenhando a periferia: a região administrativa norte de Natal/RN, na última década do século XX, servicializada na Av. Dr. João Medeiros Filho

The tertiary sector has been (re)defining and (re)qualifying, in an impacting way, the urban spaces in the cities, introducing new elements for the discussion of the relationship center/periphery. In Natal, as an inducing economic activity of its development, it conforms to the new needs of the capital, expanding, being materialized through several processes and spatial forms. We aim at analyzing one of those processes, which has taken its Northern Administrative Area to (re)define the design of its urban space, through the actions developed by the agents involved with the spatialization of the tertiary activities, at the same time as it redimensions its role as a periphery of Natal, contributing to the study of the recent and growing transformations of the Brazilian capitals. The studied district corresponds to 39.4% of the municipal area and, until recently, was composed by precarious reproduction spaces, unprovided of relevant economical activities. After the boom of the development of extensive housing complexes by SFH/BNH, the area, gradually stopped being a dependent area, and it imposed itself as an economically participant region, with the increase of the trade and services sectors, as well as a favorable place for the appearance of new activities. Its reflexes are noticeable in the achieved spatial configuration. As the main road to induct changes, Dr. João Medeiros Filho Avenue presents these new tendencies in the production of the intraurban space, concentrating the largest goods and services equipments of the area, through investments of the private and public sectors, which guarantee the capital allocation for the construction of a new centrality

Adequação bioclimática para os espaços urbanos abertos do centro de Fortaleza, CE

This research presents a study investigating the correlation between the environmental-physycal charcateristics of cities and the formation of its micro-climates. The study was conducted in the central area of Fortaleza characterized as a stable and consolidated area, where the city originated and currently faces serious problems in its urban dynamics. The points of measurements were determined by the elaboration and analysis of topography maps, height of buildings, land use, type of surface coating and vegetation, following the methodology of Katzschner (1997). A zoning map was then determined, according to common morphological characteristics of the 12 measurement points, which were based on a set of Romero s (2001) bioclimatic criteria. Air measurements, temperature, humidity, intensity and direction of winds were made in transect form in two different circuits in the study area, with six points of data collection in each area, in three different times: 6:00 am, 1:00pm and 7:00pm, during two periods of the year: August 2008 and March 2009. The results verified the influence of different environmental-physical types in the behavior of the climatic variables that were collected. A verticalização tão condenada em algumas situações se bem equilibrada e controlada pode reduzir as temperaturas do ar através do sombreamento dos espaços urbanos e possibilidade de maior permeabilidade a ventilação natural. The highest average air temperature and lower humidity were recorded at the point I at all times. This situation may have been in result of the high density, poor vegetation and extended paving of the ground. According to the results, it s clear the positive influence vegetation has on easing air temperature. Another indicator observed that areas with a greater variation in building heights tend to present decreased average air temperature. High rise structure, planned in accordance to urban air quality parameters, can reduce air temperatures by the shading of urban spaces and the possibility of greater penetration of natural ventilation
