Au début des années 1920, la ville de Montréal se retrouve dans une situation assez unique. À l’époque, les États-Unis et toutes les provinces canadiennes à l’exception du Québec ont adopté la prohibition de la vente d’alcool. Mais même au Québec, environ la moitié de la population de la province est alors touchée par des prohibitions locales (votées au niveau municipal), des prohibitions qui ont largement perduré tout au long de la période à l’étude. Durant cette ère de prohibition de l’alcool nord-américaine, Montréal est la plus grande ville, et une des seules sur le continent non régie par une loi sur la prohibition. C’est aussi celle qui dispose des lois les plus libérales envers l’alcool des deux côtés du 49ème parallèle grâce à la création de la Commission des Liqueurs de Québec (CLQ), le premier système de contrôle gouvernemental de l’alcool en Amérique du Nord. C’est dans ce contexte que Montréal devient une rare oasis dans un continent assoiffé et le plus grand cobaye du modèle de contrôle gouvernemental de l’alcool. Ce mémoire examine les impacts de cette conjoncture sur le développement de cette ville, de son industrie touristique, de sa vie nocturne et de sa réputation. En premier lieu, le mémoire présente une mise en contexte de la situation aux États-Unis, au Canada et au Québec afin de faire ressortir le caractère unique de Montréal pendant cette période. En deuxième lieu, l’essor du tourisme dit « de liqueur » et de la vie nocturne montréalaise, à la fois légale et illicite, est exploré. En dernier lieu, le mémoire met au jour l’impact que cette conjoncture a eu sur la construction de la réputation de la ville à travers l’examen des écrits des anti- et pro-prohibitionnistes qui ont chacun propagé des visions idéalisées et démonisées de cette ville « bien arrosée », ainsi que des documents associés à l’essor du tourisme, tels que les chansons, les guides touristiques et les récits de voyage, qui, pour leur part, ont présenté un image plus romancée de la métropole et associée à un refuge festif de la prohibition. Malgré leurs différences, ces trois visions de Montréal l’ont néanmoins associée à la liberté, que ce soit une liberté ordonnée, dangereuse ou bien émancipatrice. Ainsi, à partir de l’expérience de la prohibition et du tourisme de liqueur, Montréal devient connue comme une ville « ouverte », dans ses acceptions à la fois positives et négatives.

Cette lecture, tant critique, comparative, et théorique que pédagogique, s’ancre dans le constat, premièrement, qu’il advient aux étudiantEs en littérature de se (re)poser la question des coûts et complicités qu’apprendre à lire et à écrire présuppose aujourd’hui; deuxièmement, que nos pratiques littéraires se trament au sein de lieux empreints de différences, que l’on peut nommer, selon le contexte, métaphore, récit, ville; et, troisièmement, que les efforts et investissements requis sont tout autant couteux et interminable qu’un plaisir et une nécessité politique. Ces conclusions tendent vers l’abstrait et le théorique, mais le langage en lequel elles sont articulées, langage corporel et urbain, de la dépendance et de la violence, cherche d’autant plus une qualité matérielle et concrète. Or, l’introduction propose un survol des lectures et comparaisons de Heroine de Gail Scott qui centre ce projet; identifie les contextes institutionnels, historiques, et personnels qui risquent, ensuite, de décentrer celui-ci. Le premier chapitre permet de cerner le matérialisme littéraire qui me sert de méthode par laquelle la littérature, à la fois, sollicite et offre une réponse à ces interrogations théoriques. Inspirée de l’œuvre de Gail Scott et Réjean Ducharme, premièrement, et de Walter Benjamin, Elisabeth Grosz, et Pierre Macherey ensuite, ‘matérialisme’ fait référence à cette collection de figures de pratiques littéraires et urbaines qui proviennent, par exemple, de Georges Perec, Michel DeCerteau, Barbara Johnson, et Patricia Smart, et qui invitent ensuite une réflexions sur les relations entre corporalité et narrativité, entre la nécessité et la contingence du littéraire. De plus, une collection de figures d’un Montréal littéraire et d’une cité pédagogique, acquis des œuvres de Zygmunt Bauman, Partricia Godbout, et Lewis Mumford, constitue en effet un vocabulaire nous permettant de mieux découvrir (et donc enseigner) ce que lire et apprendre requiert. Le deuxième chapitre propose une lecture comparée de Heroine et des romans des auteures québécoises Anne Dandurand, Marie Gagnon, et Tess Fragoulis, dans le contexte, premièrement, les débats entourant l’institutionnalisation de la littérature (anglo)Québécoise et, deuxièmement, des questions pédagogiques et politiques plus larges et plus urgentes que nous pose, encore aujourd’hui, cette violence récurrente qui s’acharna, par exemple, sur la Polytechnique en 1989. Or, cette intersection de la violence meurtrière, la pratique littéraire, et la pédagogie qui en résulte se pose et s’articule, encore, par le biais d’une collection de figures de styles. En fait, à travers le roman de Scott et de l’œuvre critique qui en fait la lecture, une série de craques invite à reconnaître Heroine comme étant, ce que j’appelle, un récit de dépendance, au sein duquel se concrétise une temporalité récursive et une logique d’introjection nous permettant de mieux comprendre la violence et, par conséquent, le pouvoir d’une pratique littéraire sur laquelle, ensuite, j’appuie ma pédagogie en devenir. Jetant, finalement, un regard rétrospectif sur l’oeuvre dans son entier, la conclusion de ce projet se tourne aussi vers l’avant, c’est-à-dire, vers ce que mes lectures dites matérialistes de la littérature canadienne et québécoise contribuent à mon enseignement de la langue anglaise en Corée du Sud. C’est dans ce contexte que les propos de Jacques Rancière occasionnent un dernier questionnement quant à l’historique des débats et des structures pédagogiques en Corée, d’une part, et, de l’autre, les conclusions que cette lecture de la fiction théorique de Gail Scott nous livre.

The thesis entitled "Studies on the eco-physiology of heterotrophic and indicator bacteria in the marine environments of Kerala" embodies the results of an investigation carried out by the candidate at the Central Marine Fisheries Research Institute, Cochin. It is presentedd under 4 chapters in two parts (Parts A & B) and includes 6 sections. The material for the study was collected in the Cochin backwater during April 1972 to February. 1973, March 1974 to February 1975, July 1975 to June 1976 and in the ishore area during January to October, 1978 and an account of the heterotropic and indicator bacteria are given with intensity charts and tables. Samples from all the stations contained significant quantities of heterotrophs (Part A, Section I) and faecal pollution indicators (Section II). Maximum number of heterotrophic bacteria was observed during the postmonsoon period. The total counts betwen one station and the other did not vary as much as the counts between months did. The distribution was characterised by overdispersion. During 1972-73 in all the stations except the fourth the minimum heterotrophs (Total counts) were recorded during the monsoon period. Minimum counts were observed during the premonsoon period, with an increasing trend from the premonsoon to postmonsoon seasons. Maximum counts were recorded during monsoon months during 1974-75. No significant difference was noted in the total plate count between stations, months and regions. Seasonal variations in sea water was meagre during 1975-76, whereas in sediments variations were prominent during monsoon in Station I - near the mouth of the sewage effluent of Cochin City and in postmonsoon at Station II in the Mattancherry Channel and Station III near barmouth

An efficient passenger road transport system is a boon to any city and an inefficient one its bane. Passenger bus transport operation involves various aspects like passenger convenience, profitability of operation and social, technological and environmental factors. The author’s interest in this area was aroused when he conducted a traffic survey of Trivandrum City in 1979. While some studies on the performance of the Kerala State Road Transport Corporation in specific areas like finance, inventory control etc. have already been made, no study has been made from the operational point of view. The study is also the first one of its kind in dealing with the transportation problems for a second order city like Trivandrum. The objective of this research study is to develop a scientific basis for analysing and understanding the various operational aspects of urban bus transport management like assessing travel demand, depot location, fleet allocation, vehicle scheduling, maintenance etc. The operation of public road transportation in Trivandrum City is analysed on the basis of this theoretical background. The studies made have relevance to any medium sized city in India or even abroad. If not properly managed, deterioration of any public utility system is a natural process and it adversely affects the consumers, the economy and the nation. Making any system more efficient requires careful analysis, judicious decision making and proper implementation. It is hoped that this study will throw some light into the various operational aspects of urban passenger road transport management which can be of some help to make it perform more efficiently

Kochi, the commercial capital of Kerala, South India and second most important city next to Mumbai on the Western coast is a land having a wide variety of residential environments. Due to rapid population growth, changing lifestyles, food habits and living standards, institutional weaknesses, improper choice of technology and public apathy, the present pattern of the city can be classified as that of haphazard growth with typical problems characteristics of unplanned urban development especially in the case of solid waste management. To have a better living condition for us and our future generations, we must know where we are now and how far we need to go. We, each individual must calculate how much nature we use and compare it to how much nature we have available. This can be achieved by applying the concept of ecological footprint. Ecological footprint analysis (EFA) is a quantitative tool that represents the ecological load imposed on earth by humans in spatial terms. The aim of applying EFA to Kochi city is to quantify the consumption and waste generation of a population and to compare it with the existing biocapacity. By quantifying the ecological footprint we can formulate strategies to reduce the footprint and there by having a sustainable living. The paper discusses the various footprint components of Kochi city and in detail analyses the waste footprint of the residential areas using waste footprint analyzer. An attempt is also made to suggest some waste foot print reduction strategies thereby making the city sustainable as far as solid waste management is concerned.

Abstract: This dissertation generally concentrates on the relationships between “gender” and “space” in the present time of urban life in capital city of Tehran. “Gender” as a changing social construct, differentiated within societies and through time, studied this time by investigation on “gender attitude” or “gender identity” means attitudes towards “gender” issues regarding Tehran residences. “Space” as a concept integrated from physical and social constituents investigated through focus on “spatial attitude” means attitudes towards using “living spaces” including private space of “house”, semi private semi public space of neighborhood and finally public spaces of the city. “Activities and practices” in space concentrated instead of “physical” space; this perspective to “space” discussed as the most justified implication of “space” in this debate regarding current situations in city of Tehran. Under a systematic approach, the interactions and interconnections between “gender” and “space” as two constituent variables of social organization investigated by focus on the different associations presented between different “gender identities” and their different “spatial identities”; in fact, “spatial identity” manifests “gender identity” and in opposite direction, “spatial identity” influences to construction of “gender identity”. The hypotheses of case study in Tehran defined as followed: • “Gender identity” is reflected on “spatial identity”. Various “gender identities” in Tehran present different perspectives of “space” or they identify “space” by different values. • As “gender identity” internalizes patriarchal oppression, it internalizes associated “spatial” oppression too. • Within the same social class, different “gender identities” related to men and women, present interconnected qualities, compared with “gender identities” related to men or women of different social classes. This situation could be found in the “spatial” perspectives of different groups of men and women too. • Following the upper hypotheses, “spatial” oppression differs among social classes of Tehran living in different parts of this city. This research undertook a qualitative study in Tehran by interviewing with different parents of both young daughter and son regarding their attitudes towards gender issues from one side and activities and behaviors of their children in different spaces from the other side. Results of case study indicated the parallel changes of parents’ attitudes towards “gender” and “spatial” issues; it means strong connection between “gender” and “space”. It revealed association of “equal” spatial attitudes with “open, neutral” gender attitudes, and also the association of “biased, unequal” spatial identities with “conservative patriarchal” gender identities. It was cleared too that this variable concept – gender space - changes by “sex”; mothers comparing fathers presented more equitable notions towards “gender spatial” issues. It changes too by “social class” and “educational level”, that means “gender spatial” identity getting more open equitable among more educated people of middle and upper classes. “Breadwinning status in the family” also presents its effect on the changes of “gender spatial” identity so participant breadwinners in the family expressed relatively more equitable notions comparing householders and housekeepers. And finally, “gender spatial” identity changes through “place” in the city and regarding South – North line of the city. The illustration of changes of “gender spatial” identity from “open” to “conservative” among society indicated not only vertical variation across social classes, furthermore the horizontal changing among each social class. These results also confirmed hypotheses while made precision on the third one regarding variable of sex. More investigations pointed to some inclusive spatial attitudes throughout society penetrated to different groups of “gender identities”, to “opens” as to “conservatives”, also to groups between them, by two opposite features; first kind, conservative biased spatial practices in favor of patriarchal gender relations and the second, progressive neutral actions in favor of equal gender relations. While the major reason for the inclusive conservative practices was referred to the social insecurity for women, the second neutral ones associated to more formal & safer spaces of the city. In conclusion, while both trends are associated deeply with the important issues of “sex” & “body” in patriarchal thoughts, still strong, they are the consequences of the transitional period of social change in macro level, and the challenges involved regarding interactions between social orders, between old system of patriarchy, the traditional biased “gender spatial” relations and the new one of equal relations. The case study drew an inhomogeneous illustration regarding gender spatial aspects of life in Tehran, the opposite groups of “open” and “conservative”, and the large group of “semi open semi conservative” between them. In macro perspective it presents contradicted social groups according their general life styles; they are the manifestations of challenging trends towards tradition and modernity in Iranian society. This illustration while presents unstable social situations, necessitates probing solutions for social integration; exploring the directions could make heterogeneous social groups close in the way they think and the form they live in spaces. Democratic approaches like participatory development planning might be helpful for the city in its way to more solidarity and sustainability regarding its social spatial – gender as well – development, in macro levels of social spatial planning and in micro levels of physical planning, in private space of house and in public spaces of the city.

The main objective of this PhD research study is to provide a perspective on the urban growth management and sustainable development in Palestine, and more specifically in Hebron district as a case study. Hebron is located 36 km south of Jerusalem, with an overall population size of around 600,000 people living in a total area around1246km2. Hebron is the biggest Palestinian district that has 16 municipalities and 154 localities. The research discusses and analyzes the urban planning system, economical and environmental policies and the solution required to manage and integrate the development elements to develop a sustainable development plan for Hebron. The research provides answers for fundamental questions such as what kind and definition of sustainable development are applicable to the Palestinian case?. What are the sustainability problems there and how the Israeli occupation and unstable political condition affect the sustainable development in Palestine? What are the urban growth management and sustainability policies and actions required from government, public and privets sector in Palestine? The fast urban growth in Palestine is facing many problems and challenges due to the increase in the population size and the resulting impact of this increase including, but not limited to, the demand of new houses, need for more infrastructure services, demands on new industrial, commercial, educational and health projects, which in turn reduces the area of agricultural lands and threatens the natural resources and environment. There are also other associated sustainability problems like the absence of effective plans or regulations that control urban expansion, the absence of sufficient sustainable development plans at the national levels for the district, new job requirements, Israeli restrictions and occupation for more than 60 years, existence of construction factories near residential areas, poor public awareness and poor governmental funds for service projects and development plans. The study consists of nine chapters. Chapter One includes an introduction, study objectives, problems and justifications, while Chapter Two has a theoretical background on sustainability topic and definitions of sustainability. The Palestinian urban planning laws and local government systems are discussed in Chapter Three and the methodology of research is detailed in Chapter Four. As for Chapter Five, it provides a general background on Hebron District including demographical and economical profiles, along with recommendations related to sustainable development for each profile Chapter Six addresses the urban environment, sustainability priorities and policies required. Chapter Seven discusses and analyzes infrastructure services including transportation, water and wastewater. As for Chapter Eight, it addresses the land use, housing and urban expansion beside the cultural heritage, natural heritage with relevant sustainable development polices and recommendations. Finally, Chapter Nine includes a conclusion and comprehensive recommendations integrating all of urban and sustainability event in one map. Hebron has a deep history including a rich cultural heritage aged by thousands of years, with 47% of Hebron district population under 14 years old. Being the biggest Palestinian district, Hebron has thousands of industrial and economical organizations beside a large agricultural sector at Palestine level. This gives Hebron a potential to play major roles in developing a national sustainability plan, as the current urban planning system in Palestine needs urgent reform and development to fulfill the sustainability requirement. The municipalities and ministers should find permanent financial aid for urban planning and development studies so as to face future challenges. The Palestinian government can benefit from available local human resources in development projects; hence Palestinian people have sufficient qualifications in most sectors. The Palestinian people also can invest in the privet sector in Palestine in case businessmen have been encouraged and clear investment laws and plans have been developed. The study provides recommendations associated to the sustainable development in Palestine in general and Hebron, as a case study, in specific. Recommendations include increasing the privet sector as well as the public involvement in urban growth management, and stopping unplanned urban expansion, subjecting granting building permits of new projects to the no-harm environmental impact assessment, increasing the coordination and cooperation between localities and central bodies, protection and renovation of old cites and green areas, increasing the quality and quantity of infrastructure services, establishing district urban planning department to coordinate and organize urban planning and sustainable development activities. Also, among recommendations come dividing Hebron into three planning and administrative areas (north, central and south), and dividing the sustainable development and implementation period (2010 to 2025) into three main phases. Finally, the study strongly recommends benefiting from the same urban development plans in similar districts at national and international levels, also to use new technologies and information systems in urban planning process.

Durante la crisis financiera global de 2008 muchas organizaciones y mercados financieros tuvieron que terminar sus operaciones o replantearlas debido a los choques que golpearon el bienestar de sus empresas. A pesar de esta grave situación, en la actualidad se pueden encontrar empresas que se recuperaron y salieron del terrible panorama que les presentó la crisis, incluso encontrando nuevas oportunidades de negocio y fortaleciendo su futuro. Esta capacidad que algunas organizaciones tuvieron y que permitió su salida victoriosa de la crisis se denomina resiliencia, la cual es la capacidad de sobreponerse a los efectos negativos de choques internos o externos (Briguglio, Cordina, Farrugia & Vella 2009). Por tanto en el presente trabajo se estudiará esta capacidad tanto en la organización como en los líderes para hallar factores que mejoren el desempeño de las empresas en crisis como la que ocurrió en el 2008 – 2009. Primero se realizará un estudio sobre los sucesos y el desarrollo de la crisis subprime del año 2008 para tener un entendimiento claro de sus antecedentes, desarrollo, magnitud y consecuencias. Posteriormente se realizará un estudio profundo sobre la teoría de la resiliencia organizacional y la resiliencia en el líder como individuo y los estilos de liderazgo. Finalmente teniendo un sustento teórico tanto de la crisis como del concepto de resiliencia se tomarán casos de estudio de empresas que lograron perdurar en la crisis financiera del 2008 y empresas que no lograron sobrevivir para posteriormente hallar características del líder y del liderazgo que puedan aumentar o afectar la capacidad de resiliencia de las organizaciones con el objetivo de brindar herramientas a los líderes actuales para que manejen de forma eficiente y eficaz las empresas en un mundo complejo y variable como el actual.

Purpose: To examine the ‘interrater reliability’ of the Alberta Infant Motor Scale (AIMS) in term and preterm born infants between 10 to 16 months age from Talca province, Maule Region - Chile. Subjects: 115 infants between 10 to 16 months age were incorporated to the study; 95 term born infants were attended in the local Health Centre in Talca City, and 20 preterm infants belonged to the Premature Infants Follow-Up Programme of Talca Regional Hospital. Methods: The motor behaviour of each infant was recorded and later it was assessed by two trained assessors using AIMS. It was obtained the total AIMS’ score and also from prone, supine, seated, and stand subscales. For ‘interrater reliability’ analysis it was used the Intraclass Coefficient of Correlation (ICC), the Standard Error of Measurement (SEM) and 95% limits of agreement. Results: The obtained ICC for the total scores AIMS were major than 0.94 (p<0.0002) for term and preterm born infants. The SEM of total scores was less than 3.1 points, higher than what was found in other similar studies. The 95% limits of agreement were +5.3 to -4.1 points and +7.7 to – 3.9 points in term and preterm born, respectively, revealing ‘interrater agreement’. Conclusion: The AIMS showed adequate ‘interrater reliable’ levels when was applied in Chilean term and preterm born from 10 to 16 month’s age.

The aim of this work is to recover Henri Lefèbvre's methodological contributions for (re)thinking the right to the city, based on the need to know the appropriation of space´s dialectical triad. Empirically, it refers to the urban genesis of Mar del Plata (Argentina), an intermediate Latin American city, and its heterogeneous socio-territorial forms of appropriating inhabitance, or different forms of appropriating goods of use, that lead to think about opening to the transformation of the capitalist social order, and of its urban order, naturalized after the fetischism of private property.

La ciudad y los procesos que ésta desencadena en su entorno territorial han variado, de acuerdo con el momento histórico y contexto geográfico donde ocurrió, está ocurriendo o sucederá, por lo tanto, lo primero y lo segundo, son tan cambiantes, como lo son los elementos constitutivos de ese espacio ocupado, apropiado y gobernado.Son pocos los asuntos sobre los cuales coinciden las distintas comunidades académicas y disciplinas que se encargan del estudio de los procesos urbanos, como urbanistas, arquitectos, geógrafos, sociólogos, politólogos, ingenieros o planificadores; por ejemplo, con relación a la definición de lo urbano o lo qué podemos entender por ciudad; tal vez hay mayor acuerdo por lo que no es, como se constata con los espacios dedicados, exclusiva o principalmente a las actividades productivas agropecuarias. De la misma manera, sobre lo que se considera como espacio público, ya que algunos le dan un énfasis estructural y físico, como uno de los elementos rígidos que constituyen el espacio ocupado, mientras que otros, además de lo físico, rescatan de él referentes históricos, culturales y simbólicos.En la actualidad viene ganando audiencia la postura que combina lo físico y material de la ciudad y el espacio público, con lo inmaterial y simbólico de los mismos, lo que le confiere un nuevo sentido. De este tipo de convergencias, surge el escenario que contribuye a construir el ciudadano que requiere y demanda la ciudad.De acuerdo con lo anterior, el análisis que aquí se presenta se aborda a partir de tres aspectos relevantes: en primer lugar, se reiteran algunos de los caminos andados, para esbozar algunas de las nuevas perspectivas sobre la ciudad y el espacio público, tal como se sugiere en el título del artículo; en segundo lugar, relacionar aspectos históricos, conceptuales y aplicados sobre la ciudad y de esta con el espacio público, con base en el caso de Bogotá y finalmente plantear algunos de los desafíos que surgen de esta interacción, a partir de algunas reflexiones que buscan vincular esta temática con las ciencias sociales y en particular con la ciencia política.-----The city and the processes triggered by the city in its territorial environment have changed, according to the historical moment and the geographical context in which it happened, is happening, or will happen; therefore, the former and the latter are as changing as the elements of that occupied, appropriated, and governed space.There are very few subjects on which there is an agreement among the different academic communities and disciplines that study urban processes, such as town planners, architects, geographers, sociologists, political scientists, engineers, or planners. For example, regarding the definition of the urban matters or what we may understand as a city, a greater agreement may be found on what it is not, as shown with spaces exclusively or mainly dedicated to the productive agricultural/livestock activities. Likewise, regarding what is deemed as public space, because some people stress the structural and physical aspect as one of the rigid elements that comprise the occupied space, while others rescue, in addition to the physical, the historical, cultural, and symbolic references.The position that considers the physical and material city and public space combined with their immaterial and symbolic aspects has been gaining terrain lately, providing them with a whole new sense. From these convergences arises the scenario that contributes to the building of the citizenship required and demanded by the city.According to the foregoing, the analysis presented here is addressed from three relevant aspects: First, reiterating some of the already treated topics to outline some new perspectives on the city and the public space, as suggested in the title of this article; second, relating historical, conceptual, and applied aspects of the city and such aspects of the city related to the public space, based on the case of Bogotá; and finally, formulating some challenges arising form this interaction, based on certain thoughts that seek to link this topic with the Social Sciences and, in particular, with the Political Sciences.

Este trabajo examina la teoría sobre guerras civiles y resolución de conflictos con el fin de contestar la pregunta: ¿por qué fracasan o progresan los procesos de paz? Se miraron los procesos de paz en Colombia en los últimos cinco años cuando comenzó y fracasó el proceso de paz con las Fuerzas Armadas Revolucionarias de Colombia, FARC y comenzaron con las Autodefensas Unidas de Colombia, AUC. La teoría revela la relevancia de factores económicos, políticos, participación externa y militares para explicar por que fallan o prosperan los procesos de paz. Por su parte, el fracaso de las negociaciones con las FARC puede explicarse por razones de estrategia militar, el rol de la violencia durante la negociación y la falta de participación internacional. De otro lado, evitando todos los puntos sensibles de la negociación inicial, las AUC ganaron apoyo de la opinión publica y la confianza del gobierno para iniciar los diálogos. De esta forma, tenemos dos procesos recientes en Colombia para analizar: uno que fallo y el otro que esta progresando. El análisis de estos procesos puede ayudarnos a contestar la pregunta inicial de este trabajo.

La configuración de lugares como áreas de protección ambiental puede ser vista como un proceso técnico y objetivo, en el que se crean políticas públicas que definen prácticas adecuadas e inadecuadas en el lugar. Pero esta configuración es un proceso histórico y negociado. Este se construye en contante diálogo entre diferentes actores que se preocupan por definir qué es la naturaleza y el cuidado ambiental, y las percepciones que individuos que habitan en o cerca a estos lugares construyen en su diario vivir. Es así como la configuración socioambiental de lugares como áreas de protección ocurre por transformaciones en la forma de percibir un lugar, la relaciones con este y sobre todo, prácticas y relaciones que se traducen en formas de negociar nociones de naturaleza y cuidado ambiental. Esta negociación tiene grandes implicaciones en los individuos, particularmente en su subjetividad. Es decir, en hechos como la forma de nombrarlo, caminarlo, observar las especies, iniciar proyectos de agricultura orgánica, cambiar prácticas productivas, el cerramiento de zonas para proteger las fuentes de agua o zonas de vegetación. También sobre su subjetividad, la manera como se sienten frente al lugar, como juzgan sus acciones y las de otros y cómo construyen objetivos personales con respecto a la idea de cuidado ambiental.

The objective of this paper is to introduce a diVerent approach, called the ecological-longitudinal, to carrying out pooled analysis in time series ecological studies. Because it gives a larger number of data points and, hence, increases the statistical power of the analysis, this approach, unlike conventional ones, allows the complementation of aspects such as accommodation of random effect models, of lags, of interaction between pollutants and between pollutants and meteorological variables, that are hardly implemented in conventional approaches. Design—The approach is illustrated by providing quantitative estimates of the short-termeVects of air pollution on mortality in three Spanish cities, Barcelona,Valencia and Vigo, for the period 1992–1994. Because the dependent variable was a count, a Poisson generalised linear model was first specified. Several modelling issues are worth mentioning. Firstly, because the relations between mortality and explanatory variables were nonlinear, cubic splines were used for covariate control, leading to a generalised additive model, GAM. Secondly, the effects of the predictors on the response were allowed to occur with some lag. Thirdly, the residual autocorrelation, because of imperfect control, was controlled for by means of an autoregressive Poisson GAM. Finally, the longitudinal design demanded the consideration of the existence of individual heterogeneity, requiring the consideration of mixed models. Main results—The estimates of the relative risks obtained from the individual analyses varied across cities, particularly those associated with sulphur dioxide. The highest relative risks corresponded to black smoke in Valencia. These estimates were higher than those obtained from the ecological-longitudinal analysis. Relative risks estimated from this latter analysis were practically identical across cities, 1.00638 (95% confidence intervals 1.0002, 1.0011) for a black smoke increase of 10 μg/m3 and 1.00415 (95% CI 1.0001, 1.0007) for a increase of 10 μg/m3 of sulphur dioxide. Because the statistical power is higher than in the individual analysis more interactions were statistically significant,especially those among air pollutants and meteorological variables. Conclusions—Air pollutant levels were related to mortality in the three cities of the study, Barcelona, Valencia and Vigo. These results were consistent with similar studies in other cities, with other multicentric studies and coherent with both, previous individual, for each city, and multicentric studies for all three cities
