Condomínios fechados: a produção habitacional contemporânea e a auto-exclusão dos ricos no espaço urbano de Natal RN (1995 2003)

The present work analyzes the fast evolution of gated communities in Natal-RN´s urban space. Characterized by the occupation of large areas, providing private security and utilities, this kind of real estate use arises a long list of questions and issues from society and scholars, due to privatization of urban space, bending of law constraints and the lack of an integrated planning of the cities where they are built. The reasons for its fast growth in Brazil s urban areas are analyzed, considering the impact on formal urban planning and municipal services and on the identification of urbanistic, architectural pattern and constraints, as well as legal, social and economic issues. This study is based on the detailed analysis of the first three units of gated communities built in the urban space in Natal, between 1995 and 2003, including their evolution throughout time and the specific social and economic reasons for its present widespread adoption in Brazilian real estate market and, particulary, in our city. The main objective of this piece of work is to answer the why s and how s these phenomena evolved, setting a basis for the definition of adequate public policies and regulation of this kind of urban land use

Paisagem, um patrimônio esquecido: subsídios para a construção de uma metodologia de valoração e proteção do cenário natural litorâneo

The so-called "residential tourism" came to intensify the previous occupation of the coastal zones, characterized by traditional beach houses, and brought significant consequences for their spatial configuration, and especially for its scenic value of the landscape. Although there is the intention to regulate the activities of enterprising groups by some legal instruments to control the use and occupation of land, and to contain some negative effects, the actions of government are still inefficient in trying to follow the implications on the landscape from the accelerated growth of the real estate and touristic sectors. Supported in the speech of economic development and income generation, public managers prioritize areas to attract tourists to the detriment of preserving important physical attributes of the natural environment that contribute significantly to the quality of life. The result can be noticed in the use of natural elements as one of the major components in the land valorization, and in the immediate attraction of investors and enterprising. Therefore, the objective of this work is to contribute to the debate on the landscape preservation a little detailed thematic in view of their relevance in the current context - by indicating subsidies to the creation of a methodology for the evaluation and protection of coastal zones that may assist the government in creating new instruments, and better prepare it in control of the occupation of these areas. For such, was followed two ways to analysis: the indirect method and the direct method. The first is grounded in the evaluation of landscape attributes, which is based on the work of Raquel Tardin (2008) and Eduardo Cuesta, Encarnación Algarra and Isabel Pastor (2001). The second, based on the research of Leticia and Carlos Hardt (2010) and on the concepts of phenomenology - expressed by Antonio Christofoletti (1985) and Yi-Fu Tuan (1983) - considers the population perspective on the quality of the natural scenery. Developed through cartographic materials, photographic collections and quantitative tables, this dissertation utilized as a case study the beaches of Barra de Tabatinga and Camurupim, located in the city of Nísia Floresta/RN. Despite already being sighted spaces of advanced stage of landscape degradation in these locations, areas of remarkable scenic value can still be found, what reinforce the urgency in adopting preservationists actions. The absence of laws focused on the management and protection of the landscape singularities associated with the inefficiency of the government to invigilate the land occupation in coastal zones, encourage the excessive action of the real estate-tourism, and consequently make the government the main responsible for the environmental and landscape impacts in these areas - by its omission or by their connivance. Therefore, the legislation permeates this entire process and constitutes itself as the most effective way to guarantee the right to the landscape to present and future generations. Are also pointed some important considerations to build a methodology, especially concerning possibilities of improvements and adaptations of its applicability in each case

Reutilização de imóveis de interesse patrimonial, voltados para a ahabitação: um estudo de caso na Ribeira-Natal/RN

This work analyzes the reutilization of real estate of patrimonial interest, come back toward habitation. One understands as real estate of patrimonial interest the old ones that present relevant architectural typologies that must be preserved; some buildings that represent characteristic architectural styles of a determined period; some valued real estates for the history of the city (historical, memory and image signification that has of certain places) and buildings with exceptional artistic elements. In short, real estate of patrimonial interest. The place or site to be studied will be the neighborhood of the Ribeira, because is an area that protects a bigger interest for the historic patrimony of the city. The habitation use was thought as a booster element of revitalization processes of degradable historic site, contributing to the preservation of artistic, architectural and historic patrimony, and thus to stimulate the accomplishment of the re-qualification of the neighborhood of the Ribeira. It is intended with the present study to examine alternatives to make possible habitation re (uses) in the historical quarter of the Ribeira in old constructions of patrimonial value

Conflitos ambientais no Pontal da Barra - Pelotas/RS - desde uma perspectiva etnográfica na educação ambiental

Este trabalho tem como propósito explicitar a relação de injustiça ambiental e as controvérsias entre atores sociais com distintos modos de significação e apropriação territorial no contexto de um conflito ambiental na localidade do Pontal da Barra, praia do Laranjal, Pelotas - RS. Desde uma perspectiva etnográfica, objetiva-se incorporar a dimensão do conflito enquanto elemento central de análise. Para isso, partiu-se da proposta analítica de explicitação do conflito como forma de mapeamento dos diferentes atores sociais em interação, contemplando suas visões, posições, interesses, discursos e estratégias de disputa e legitimação no campo ambiental. Consiste em um conflito ambiental que insurgiu a partir da proposta de implantação de um loteamento residencial no contexto de urbanização do balneário do Laranjal durante a década de 1980, envolvendo os seguintes atores sociais: moradores removidos e os que permanecem no Pontal da Barra; membros da comunidade científica e movimento ambientalista local; empresário do ramo imobiliário e turístico no Pontal da Barra e a intervenção de instâncias públicas. Destaca-se a posição dos moradores, vistos em situação de marginalidade, que passaram a representar obstáculos e entraves, tanto para os interesses imobiliários e turísticos na localidade como para uma parcela significativa de ambientalistas que visam à preservação integral da área do Pontal da Barra. Em conjunto a essas iniciativas de grupos organizados sobressai a posição do Estado enquanto mediador desses conflitos e agente que procura executar estratégias de controle e planejamento do espaço, envolvendo as disputas territoriais e os discursos ambientais em questão. Perante esses órgãos do Estado e setores da iniciativa privada, a situação desses moradores caracteriza-se pela irregularidade fundiária, no qual seu espaço habitado não é reconhecido como deles. Dessa forma, este trabalho foi desenvolvido a partir da seguinte questão: tendo em vista os diferentes atores sociais envolvidos, como tem se configurado, desde a década de 1980, o conflito ambiental em torno da disputa territorial pelo Pontal da Barra, Pelotas/RS. Nessa perspectiva, busca-se desconstruir a retórica hegemônica e dominante que escamoteia as diferenças e naturaliza as desigualdades entre os atores sociais envolvidos procurando silenciar e despolitizar a participação pública no debate dos conflitos ambientais, para, através desse entendimento, corroborar com a discussão de uma Educação Ambiental crítica que tenha nos conflitos existentes a sua pauta de pesquisa e de ação.

The impact of indoor air quality and contaminants on respiratory health of older people living in long-term care residences in Porto

Background: persons who are 65 years or older often spend an important part of their lives indoors thus adverse indoor climate might influence their health status. Objective: to evaluate the influence of indoor air quality and contaminants on older people’s respiratory health. Design: cross-sectional study. Setting: 21 long-term care residences (LTC) in the city of Porto, Portugal. Subjects: older people living in LTC with ≥65 years old. Methods: the Portuguese version of BOLD questionnaire was administered by an interviewer to older residents able to participate (n = 143). Indoor air contaminants (IAC) were measured twice, during winter and summer in 135 areas. Mixed effects logistic regression models were used to study the association between the health questionnaire results and the monitored IAC, adjusted for age, smoking habits, gender and number of years living in the LTC. Results: cough (23%) and sputum (12%) were the major respiratory symptoms, and allergic rhinitis (18%) the main selfreported illness. Overall particulate matter up to 2.5 micrometres in size median concentration was above the reference levels both in winter and summer seasons. Peak values of particulate matter up to 10 micrometres in size (PM10), total volatile organic compounds, carbon dioxide, bacteria and fungi exceeded the reference levels. Older people exposed to PM10 above the reference levels demonstrated higher odds of allergic rhinitis (OR = 2.9, 95% CI: 1.1–7.2). Conclusion: high levels of PM10 were associated with 3-fold odds of allergic rhinitis. No association was found between indoor air chemical and biological contaminants and respiratory symptoms.

A Multidimensional Approach to Social Support: the Questionnaire on the Frequency of and Satisfaction with Social Support (QFSSS)

The Questionnaire on the Frequency of and Satisfaction with Social Support (QFSSS) was designed to assess the frequency of and the degree of satisfaction with perceived social support received from different sources in relation to three types of support: emotional, informational, and instrumental. This study tested the reliability of the questionnaire scores and its criterion and structural validity. The data were drawn from survey interviews of 2042 Spanish people. The results show high internal consistency (values of Cronbach's alpha ranged from .763 to .952). The correlational analysis showed significant positive associations between QFSSS scores and measures of subjective well-being and perceived social support, as well as significant negative associations with measures of loneliness (values of Pearson's r correlation ranged from .11 to .97). Confirmatory factor analysis using structural equation modelling verified an internal 4-factor structure that corresponds to the sources of support analysed: partner, family, friends, and community (values ranged from .93 to .95 for the Goodness of Fit Index (GFI); from .95 to .98 for the Comparative Fit Index (CFI); and from .10 to .07 for the Root Mean Square Error of Approximation (RMSEA)). These results confirm the validity of the QFSSS as a versatile tool which is suitable for the multidimensional assessment of social support.

Critique féministe matérialiste du droit civil québécois : le travail « domestique » et les violences sexuées, les « impensés » du droit du logement

Cette recherche constitue un essai de théorie critique féministe matérialiste et radicale. Elle poursuit principalement un objectif de dénonciation de la structure actuelle du droit du logement. À partir d’un cadre conceptuel fondé sur le féminisme matérialiste et radical, elle souhaite faire ressortir le point de vue de la classe des femmes dans l’habitation. Le droit du logement est ici utilisé dans un sens large, puisqu’il se réfère à la fois au logement comme phénomène juridique, mais aussi sociologique. À l’intérieur de la discipline juridique, il renvoie à l’ensemble des législations actuellement en vigueur au Québec en ce qui concerne la vie à domicile. Notre étude se concentre sur deux modes d’occupation des lieux, à travers le droit de propriété et le système locatif. Le droit au logement fait l’objet d’une reconnaissance internationale dans les textes portant sur les droits humains. Il est reconnu comme le « droit à un logement suffisant ». Au Canada et au Québec, il ne fait pas l’objet d’une reconnaissance explicite, malgré les engagements pris sur la scène internationale. Un portrait statistique, appuyé sur le critère du sexe, permet de mettre en évidence qu’il existe des écarts entre les hommes et les femmes en ce qui concerne la mise en application du droit du logement. Les femmes accèdent plus difficilement à un logement; elles y effectuent la majorité du travail domestique, de service et de « care » et elles sont les principales victimes des violences commises à domicile. Dans le système d’habitation, l’expérience des femmes se comprend comme une appropriation à la fois privée et collective par la classe des hommes, telle que réfléchie par Colette Guillaumin, qui se concentre autour de la division sexuelle du travail et des violences sexuées. Le droit du logement, dans sa forme actuelle, repose sur l’appropriation de la force de travail des femmes et de leur corps. Ces deux critères permettent de construire une grille d’analyse féministe matérialiste et radicale pour analyser la structure du droit du logement, tel que conçu en droit civil. Cette analyse féministe permet également de situer le droit étatique comme une pratique patriarcale. Cette dernière contribue à assurer le maintien du système d’habitation, qui est assimilable à un système hégémonique, au sens développé par Gramsci. Cette étude réfléchit sur le droit du logement dans le climat politique néolibéral. Le néolibéralisme est développé comme une idéologie qui impose une rationalité marchande à l’ensemble des politiques étatiques. À partir d’une méthode décrite comme métathéorique externe radicalement réflexive, puisqu’elle propose l’importation d’outils conceptuels étrangers à la discipline du droit moderne, nous réfléchissons de manière radicale la construction du droit civil et des institutions qui encadrent le droit du logement. La collecte des données s’effectue à partir de la recherche documentaire. Quatre institutions du droit civil seront examinées dans le détail, soit le sujet du droit, la dichotomie privé/public, la médiation du droit du logement par les biens immeubles, à travers le rapport contractuel et le droit de propriété, et finalement les notaires. L’analyse féministe du sujet du droit insiste sur un paradoxe. D’une part, l’universalité présumée de ce sujet, laquelle permet de poser l’égalité et la liberté pour toutes les personnes juridiques. Or, plutôt que d’être neutre sexuellement comme le prétend le droit positif, nous démontrons comment ce sujet est constamment un membre de la classe des hommes. D’autre part, nous analysons comment le droit reconnaît le sexe de ses sujets, mais surtout comment cette sexualité est construite sur l’idéologie naturaliste. Ce modèle de sujet masculin est fondamental dans la construction du droit du logement. L’étude féministe de la dichotomie privé/public en fait ressortir le caractère situé. En effet, si par essence aucun domaine ou enjeu n’est en soit privé ou public, le processus de qualification, lui, est un acte de pouvoir. Nous verrons comment le droit civil crée des zones de droit privé, comprises comme des zones de non-droit pour les femmes. La qualification de privé dévalue également le travail accompli par cette classe de sexe. Le droit du logement est pourtant centré sur le rapport contractuel et sur le droit de propriété. Il importe alors d’examiner la nature du consentement donné par les femmes comme groupe social dans les contrats de vente et de location. Ces contrats ne prennent pas en compte l’expérience des femmes dans leur formation. Les catégories qui y sont attachées, telles que vendeur.e ou locataire, représentent le point de vue de la classe des hommes. Bien que la popularité de la copropriété auprès de la classe des femmes semble porteuse d’un vent de changement, nous analysons comment le discours dominant qui l’entoure instrumentalise certaines revendications féministes, tout en laissant dans l’ombre la question du travail domestique et des violences sexuées. Finalement, nous nous intéressons aux notaires en les repensant comme des intellectuel.les organiques, tels que conçu.es par Gramsci, pour la classe des hommes. Cette fonction d’intellectuel.les permet de mettre en lumière comment chaque transaction immobilière favorise la reproduction des intérêts patriarcaux, remettant ainsi en question la nature des devoirs de conseil et d’impartialité du notariat. À la lumière de cette analyse, le Code civil du Québec est qualifié dans une perspective féministe matérialiste et radicale pour devenir un système qui institutionnalise l’appropriation des femmes par l’entremise du droit du logement. Ce travail de recherche permet d’envisager certaines pistes de réflexion pour des rénovations potentielles des pratiques juridiques entourant le droit du logement, notamment la pratique notariale, tournées vers des objectifs féministes de justice sociale.

Effects of nitrogen limitation on Dunaliella sp.–Alteromonas sp. interactions: from mutualistic to competitive relationships.

Interactions between photosynthetic and non-photosynthetic microorganisms play an essential role in natural aquatic environments and the contribution of bacteria and microalgae to the nitrogen cycle can lead to both competitive and mutualistic relationships. Nitrogen is considered to be, with phosphorus and iron, one of the main limiting nutrients for primary production in the oceans and its availability experiences large temporal and geographical variations. For these reasons, it is important to understand how competitive and mutualistic interactions between photosynthetic and heterotrophic microorganisms are impacted by nitrogen limitation. In a previous study performed in batch cultures, the addition of a selected bacterial strain of Alteromonas sp. resulted in a final biomass increase in the green alga Dunaliella sp. as a result of higher nitrogen incorporation into the algal cells. The present work focuses on testing the potential of the same microalgae–bacteria association and nitrogen interactions in chemostats limited by nitrogen. Axenic and mixed cultures were compared at two dilution rates to evaluate the impact of nitrogen limitation on interactions. The addition of bacteria resulted in increased cell size in the microalgae, as well as decreased carbon incorporation, which was exacerbated by high nitrogen limitation. Biochemical analyses for the different components including microalgae, bacteria, non-living particulate matter, and dissolved organic matter, suggested that bacteria uptake carbon from carbon-rich particulate matter released by microalgae. Dissolved organic nitrogen released by microalgae was apparently not taken up by bacteria, which casts doubt on the remineralization of dissolved organic nitrogen by Alteromonas sp. in chemostats. Dunaliella sp. obtained ammonium-nitrogen more efficiently under lower nitrogen limitation. Overall, we revealed competition between microalgae and bacteria for ammonium when this was in continuous but limited supply. Competition for mineral nitrogen increased with nitrogen limitation. From our study we suggest that competitive or mutualistic relationships between microalgae and bacteria largely depend on the ecophysiological status of the two microorganisms. The outcome of microalgae–bacteria interactions in natural and artificial ecosystems largely depends on environmental factors. Our results indicate the need to improve understanding of the interaction/s between these microbial players

La expansión urbanizadora en el interior alicantino. Indicadores e incertidumbres

El fin del último periodo de expansión urbanizadora en 2006, coincide con el inicio de una crisis productiva que ha provocado que multitud de planes urbanísticos, iniciados o no, sean paralizados o descartados. Se trata de un urbanismo latente que genera grandes incertidumbres sobre municipios que habían apostado fuertemente por el crecimiento urbano. Esta situación se observa en la provincia de Alicante, especialmente en zonas de interior que experimentan un auge inmobiliario desde el año 2000. La comunicación analiza la expansión urbanizadora provincial en el periodo 2000-2006 y plantea las incertidumbres generadas por los más de 30 proyectos urbanísticos latentes en las comarcas interiores del Alto y Medio Vinalopó.
