Vers le haut : la valeur d’usage du toit vert privé : le point de vue de professionnels de l’immobilier œuvrant sur le Plateau Mont-Royal

Cette recherche s’intéresse à la valeur d’usage du toit vert dans l’arrondissement du Plateau Mont-Royal, de la Ville de Montréal. Spécifiquement, elle s’intéresse à l’état problématique qu’est l’étalement urbain en tentant l’estimation de la valeur d’usage du toit vert, de la cour arrière et du balcon-terrasse soutenue par le dispositif argumentaire immobilier propre à chacun des aménagements. L’étalement urbain est la source de graves problèmes et la résorption de ses effets néfastes est devenue une priorité dans l’aménagement du territoire. L’une des principales raisons sousjacentes à l’exode urbain est la valeur d’usage accordée à la parcelle extérieure qu’offre l’habitat unifamilial pavillonnaire. Dans cette situation, la question est de savoir si l’insertion d’espaces verts privés en milieu urbain peut participer à la résorption de l’exode urbain. Or, dans l’agglomération, le sol manque. Le toit vert privé apparaît comme une alternative astucieuse, bien que limitée, au terrain entourant la maison. Reste à savoir si les gens le valorisent tel un espace vert privé d’extrême proximité, à même le sol. À la lueur de l’analyse, il advient que le toit vert ne présente pas de valeur d’usage comparable à celle de la cour arrière dans le contexte observé, précisément parce que leurs publics cibles s’opposent d’emblée. En revanche, le balcon-terrasse et le toit vert semblent être, en fonction des données construites, des aménagements à valeur d’usage comparable.

Les patterns de Christopher Alexander appliqués aux cuisines domiciliaires modernes

La présente recherche traite des conflits d’aménagement pouvant être décelés dans les cuisines domiciliaires modernes. L’ajout d’objets mécanisés au rituel alimentaire quotidien a su changer la dynamique du lieu. En effet, l’architecture des cuisines modernes en Occident présente de grandes contradictions. Basées sur des standards architecturaux, les cuisines modulaires ne reflètent pas la variété et l’unicité des aliments auxquels les cuisines sont dédiées. Les cuisines devraient être le miroir de la vivacité naturelle des aliments et des échanges humains que la nourriture génère à travers le plaisir et le partage. Dans l’espoir de proposer des outils afin de rééquilibrer la dynamique de cette pièce, un cadre théorique basé sur les théories architecturales de l’architecte et mathématicien anglais Christopher Alexander a été établi. Supportant la présente recherche, ces théories architecturales s’inspirent de la structure et de la composition des choses de la nature et des monuments anciens afin d’établir des balises d’aménagement simples et équilibrées (qualité de vie, patterns, configuration des événements, configurations de l’espace, ...). Ces théories ont aidé à concevoir une formule d’ateliers participatifs qui visent à outiller les occupants, qui sont très souvent des non-professionnels du domaine de l’architecture et du design. Ces ateliers proposent un cheminement bien encadré qui permet aux participants de retravailler leur espace de cuisine respectif selon leurs goûts et leurs besoins. En fournissant un plan de l’étage où se situe la cuisine, quelques crayons, règles et autres matériel de dessin, les participants ont pour tâche de réaménager leur cuisine en un espace de cuisine idéal. La deuxième étape, qui elle se réalise en équipe avec tous les occupants participants de la demeure, consiste à réduire l’ampleur des changements afin d’arriver à un résultat réaliste. L’enthousiasme noté tout au long de ce processus a ainsi permis de confirmer que les non-professionnels du domaine de l’architecture et du design peuvent développer un intérêt marqué pour l’amélioration de leurs interactions quotidiennes, avec l’espace et entre les occupants, lorsque bien accompagnés dans cette tâche. Grâce aux propos et aux plans recueillis durant les séances d’ateliers participatifs ainsi qu’à l’analyse de ces données, une série d’interprétations ont émergé. Les données ont notamment démontrées l’influence positive de l’utilisation des patterns d’Alexander. L’analyse permet, en outre, de noter les tendances d’aménagement ayant émergé de l’utilisation des patterns dans les espaces de cuisine : définitivement, les cuisines se sont transformées en espace de vie partagé et polyvalent. Finalement, la présente recherche se conclut grâce à une série de recommandations qui traitent de la structure des cuisines, des ateliers participatifs et des patterns. Tout d’abord, l’impact de ces notions sur les espaces retravaillés par les participants est impressionnant. Les espaces sont bien organisés, vastes et, surtout, reflètent les occupants qui y vivent au quotidien. De plus, ayant démontré la facilité d’utilisation et la polyvalence des patterns, il a été jugé que certains aspects devraient être améliorés tels que l’actualisation de certains patterns, le prolongement du processus d’ateliers, le perfectionnement de la méthode et la diffusion des résultats.

Les articulations de l'arabité et du genre à travers les chaines d'équivalence : le cas de Uprising of Women in the Arab World

Ce mémoire de maîtrise s’intéresse aux nouvelles expressions protestataires qui ont émergé après les soulèvements connus sous le « printemps arabe » en prenant, comme objet d’analyse, Uprising of Women in the Arab World (UWAW), une page Facebook qui œuvre pour les droits des femmes à travers le « monde arabe ». Ce travail propose de saisir cette page Facebook à travers les croisements d’enjeux d’arabité et de genre, dans une perspective discursive critique. La notion d’arabité désigne une appartenance commune au « monde arabe » qui reposerait sur la production de référents religieux et linguistiques partagés par l’ensemble des pays arabes. Le genre est abordé comme un langage privilégié pour signifier les rapports de pouvoir (Scott, 1988). Afin de mettre en lumière les différentes intersections de l’arabité et du genre, je propose de recourir au concept d’articulation (Hall, 1980). Ce dernier réfère à l’assemblage de différentes pratiques de production qui constituent un discours. Cette mise en relation, non-nécessaire, s’effectue dans une conjoncture régie par les forces hégémoniques du moment. Ainsi, le concept d’articulation permet d’explorer ce que font dans leur (co)présence les discours hétérogènes par et dans lesquels l’arabité et le genre sont rendus visibles dans et à travers la page UWAW. Ces articulations sont questionnées à partir du concept de chaine d’équivalence de Laclau (2008) qui désigne une condensation de revendications hétérogènes, à travers des relations d’équivalence et de différence. Ces dernières se produisent à travers l’affirmation des particularités des revendications, tandis que les relations d’équivalence sont basées sur la mise en avant de la communalité des revendications. Cette recherche est guidée par la proposition de recherche suivante : UWAW peut être comprise comme un espace discursif traversé par des chaines d’équivalences où les articulations de l’arabité et du genre se matérialiseraient selon des relations d’équivalence et de différence. Elle fait l’objet d’une analyse critique de trois campagnes ayant eu cours sur l’UWAW en 2014. Ces dernières sont abordées comme des lieux de discours, soit des espaces construits dans et par un recours à des discours spécifiques qui participent à la production de savoirs situés dont ils sont aussi, de quelque manière, les produits. Ainsi, l’analyse s’attarde à comprendre comment la production de sens repose sur des discours concurrentiels qui puisent dans des savoirs différents qu’ils contribuent à faire circuler. L’analyse démontre la grande hétérogénéité de l’arabité qui s’est manifestée sous un visage distinct dans chaque campagne. Elle est homogénéisée et universalisée dans Do You know, clivée dans Israël Apartheid Week, et citoyenne dans « Je ne resterai pas silencieuse ». Le genre est davantage stabilisé, puisqu’il agit principalement comme force universalisante dans les trois campagnes.

Some Generalizations of Fuzzy Metrizability

The main purpose of the study is to extent concept of the class of spaces called ‘generalized metric spaces’ to fuzzy context and investigates its properties. Any class of spaces defined by a property possessed by all metric spaces could technically be called as a class of ‘generalized metric spaces’. But the term is meant for classes, which are ‘close’ to metrizable spaces in some under certain kinds of mappings. The theory of generalized metric spaces is closely related to ‘metrization theory’. The class of spaces likes Morita’s M- spaces, Borges’s w-spaces, Arhangelskii’s p-spaces, Okuyama’s  spaces have major roles in the theory of generalized metric spaces. The thesis introduces fuzzy metrizable spaces, fuzzy submetrizable spaces and proves some characterizations of fuzzy submetrizable spaces, and also the fuzzy generalized metric spaces like fuzzy w-spaces, fuzzy Moore spaces, fuzzy M-spaces, fuzzy k-spaces, fuzzy -spaces study of their properties, prove some equivalent conditions for fuzzy p-spaces. The concept of a network is one of the most useful tools in the theory of generalized metric spaces. The -spaces is a class of generalized metric spaces having a network.

Box Products in Fuzzy Topological Spaces and Related Topics

The topology as the product set with a base chosen as all products of open sets in the individual spaces. This topology is known as box topology. The main objective of this study is to extend the concept of box products to fuzzy box products and to obtain some results regarding them. Owing to the fact that box products have plenty of applications in uniform and covering properties, here made an attempt to explore some inter relations of fuzzy uniform properties and fuzzy covering properties in fuzzy box products. Even though the main focus is on fuzzy box products, some brief sketches regarding hereditarily fuzzy normal spaces and fuzzy nabla product is also provided. The main results obtained include characterization of fuzzy Hausdroffness and fuzzy regularity of box products of fuzzy topological spaces. The investigation of the completeness of fuzzy uniformities in fuzzy box products proved that a fuzzy box product of spaces is fuzzy topologically complete if each co-ordinate space is fuzzy topologically complete. The thesis also prove that the fuzzy box product of a family of fuzzy α-paracompact spaces is fuzzy topologically complete. In Fuzzy box product of hereditarily fuzzy normal spaces, the main result obtained is that if a fuzzy box product of spaces is hereditarily fuzzy normal ,then every countable subset of it is fuzzy closed. It also deals with the notion of fuzzy nabla product of spaces which is a quotient of fuzzy box product. Here the study deals the relation connecting fuzzy box product and fuzzy nabla product

Socio-Economic Dimensions of Health Care Development Among Tribals in Kerala: A Study of Tribal Communities in Wynad

The contemporary explanations and discussions of the relationship between medicine and health, and society centre around assumptions that can be broadly classified into three setsl. The first set considers health and illness as predominantly ‘biological’ and therefore, having nothing to do with the social and economic environment in which it occurs. The struggle to combat illness therefore, lies entirely within the purview of modern medicine which is neutral to economic or social change. The second considers practice of medicine as a natural science. It allows the doctor to separate himself from his subject matter, the patient, in the samelway as the natural scientist is assumed to separate himself from his subject matter, the natural world. As a 'science' and with the scientific method, it can produce unchallengable and autonomous body of knowledge which is free from the wider social and economic context. The third, different from the above, recognises the relationship between health, medicine and society. Social and environmental aspects as determinants of illness or of health comes to sharp focus here and it assigns to medicine the status of a mediator, the only viable mediator, between people and diseases. In this scheme of things the usefulness of medicine is unquestionable but the problem lies in not having enough of it to go arounds.

Understanding Recreational Services of Urban Riverfront Space for Planning Purposes

In the process of urbanization, natural and semi-natural landscapes are increasingly cherished as open space and recreational resource. Urban rivers are part of this kind of resource and thus play an important role in managing urban resilience and health. Employing the example of Tianjin, this doctoral dissertation research aims at learning to understand how to plan and design for the interface zones between urban water courses and for the land areas adjacent to such water courses. This research also aims at learning how to link waterfront space with other urban space in order to make a recreational space system for the benefit of people. Five questions of this dissertation are: 1) what is the role of rivers in spatial and open space planning? 2) What are the human needs regarding outdoor open space? 3) How do river and water front spatial structures affect people's recreational activities? 4) How to define the recreational service of urban river and waterfront open space? 5) How might answering these question change planning and design of urban open space? Quantitative and qualitative empirical approaches were combined in this study for which literature review and theoretical explorations provide the basis. Empirical investigations were conducted in the city of Tianjin. The quantitative approach includes conducting 267 quantitative interviews, and the qualitative approach includes carrying out field observations and mappings. GIS served to support analysis and visualization of empirical information that was generated through this study. By responding to the five research questions, findings and lessons include the following: 1) In the course of time rivers have gained importance in all levels and scales of spatial planning and decision making. Regarding the development of ecological networks, mainly at national scale, rivers are considered significant linear elements. Regarding regional and comprehensive development, river basins and watersheds are often considered as the structural link for strategic ecological, economic, social and recreational planning. For purposes of urban planning, particularly regarding recreational services in cities, the distribution of urban open spaces often follows the structure of river systems. 2) For the purpose of classifying human recreational needs that relate to outdoor open space Maslow's hierarchy of human needs serves as theoretical basis. The classes include geographical, safety, physiological, social and aesthetic need. These classes serve as references while analyzing river and waterfront open space and other kinds of open space. 3) Regarding the question how river and waterfront spatial structures might affect people's recreational activities, eight different landscape units were identified and compared in the case study area. Considering the thermal conditions of Tianjin, one of these landscape units was identified as affording the optimal spatial arrangement which mostly meets recreational needs. The size and the shape of open space, and the plants present in an open space have been observed as being most relevant regarding recreational activities. 4) Regarding the recreational service of urban river and waterfront open space the results of this research suggest that the recreational service is felt less intensively as the distances between water 183 front and open space user’s places of residence are increasing. As a method for estimating this ‘Service Distance Effect’ the following formula may be used: Y = a*ebx. In this equation Y means the ‘Service Distance’ between homes and open space, and X means the percentage of the people who live within this service distance. Coefficient "a" represents the distance of the residential area nearest to the water front. The coefficient "b" is a comprehensive capability index that refers to the size of the available and suitable recreational area. 5) Answers found to the questions above have implications for the planning and design of urban open space. The results from the quantitative study of recreational services of waterfront open space were applied to the assessment of river-based open space systems. It is recommended that such assessments might be done employing the network analysis function available with any GIS. In addition, several practical planning and designing suggestions are made that would help remedy any insufficient base for satisfying recreational needs. The understanding of recreational need is considered helpful for the proposing planning and designing ideas and for the changing of urban landscapes. In the course of time Tianjin's urban water system has shrunk considerably. At the same time rivers and water courses have shaped Tianjin's urban structure in noticeable ways. In the process of urbanization water has become increasingly important to the citizens and their everyday recreations. Much needs to be changed in order to improve recreational opportunities and to better provide for a livable city, most importantly when considering the increasing number of old people. Suggestions made that are based on results of this study, might be implemented in Tianjin. They are 1) to promote the quality of the waterfront open space and to make all linear waterfront area accessible recreational spaces. Then, 2), it is advisable to advocate the concept of green streets and to combine green streets with river open space in order to form an everyday recreational network. And 3) any sound urban everyday recreational service made cannot rely on only urban rivers; the whole urban structure needs to be improved, including adding small open space and optimize the form of urban communities, finally producing a multi-functional urban recreational network.

On optimal computation of MPLS label binding for multipoint-to-point connections

Most network operators have considered reducing Label Switched Routers (LSR) label spaces (i.e. the number of labels that can be used) as a means of simplifying management of underlaying Virtual Private Networks (VPNs) and, hence, reducing operational expenditure (OPEX). This letter discusses the problem of reducing the label spaces in Multiprotocol Label Switched (MPLS) networks using label merging - better known as MultiPoint-to-Point (MP2P) connections. Because of its origins in IP, MP2P connections have been considered to have tree- shapes with Label Switched Paths (LSP) as branches. Due to this fact, previous works by many authors affirm that the problem of minimizing the label space using MP2P in MPLS - the Merging Problem - cannot be solved optimally with a polynomial algorithm (NP-complete), since it involves a hard- decision problem. However, in this letter, the Merging Problem is analyzed, from the perspective of MPLS, and it is deduced that tree-shapes in MP2P connections are irrelevant. By overriding this tree-shape consideration, it is possible to perform label merging in polynomial time. Based on how MPLS signaling works, this letter proposes an algorithm to compute the minimum number of labels using label merging: the Full Label Merging algorithm. As conclusion, we reclassify the Merging Problem as Polynomial-solvable, instead of NP-complete. In addition, simulation experiments confirm that without the tree-branch selection problem, more labels can be reduced

All-Optical Label Stacking: Easing the Trade-offs Between Routing and Architecture Cost in All-Optical Packet Switching

All-optical label swapping (AOLS) forms a key technology towards the implementation of all-optical packet switching nodes (AOPS) for the future optical Internet. The capital expenditures of the deployment of AOLS increases with the size of the label spaces (i.e. the number of used labels), since a special optical device is needed for each recognized label on every node. Label space sizes are affected by the way in which demands are routed. For instance, while shortest-path routing leads to the usage of fewer labels but high link utilization, minimum interference routing leads to the opposite. This paper studies all-optical label stacking (AOLStack), which is an extension of the AOLS architecture. AOLStack aims at reducing label spaces while easing the compromise with link utilization. In this paper, an integer lineal program is proposed with the objective of analyzing the softening of the aforementioned trade-off due to AOLStack. Furthermore, a heuristic aiming at finding good solutions in polynomial-time is proposed as well. Simulation results show that AOLStack either a) reduces the label spaces with a low increase in the link utilization or, similarly, b) uses better the residual bandwidth to decrease the number of labels even more

Perdurabilidad empresarial: concepto y significados

Los grandes aportes generados por las antiguas civilizaciones y los filósofos más destacados a lo largo del tiempo, permiten entender la procedencia de algunos términos de los que hoy en día se hace uso. Estas contribuciones comienzan a través de la concepción del término tiempo, desde la antigüedad hasta los tiempos modernos, las cuales conllevan a entender que el tiempo es aquel que define la durabilidad de las cosas. De acuerdo a esto, se propone un acercamiento sobre el origen del término perdurabilidad, el cual será la base de la presente investigación. Entender la procedencia del término y el uso que se le da a sí mismo, facilita la aplicación el ámbito empresarial; el cual, a partir de diferentes posturas de autores nacionales e internacionales y basados en los parámetros que ha establecido la Universidad del Rosario, se establece un marco teórico de apoyo para futuras investigaciones dedicadas a la perdurabilidad empresarial. Asimismo, se establecen o se plasman algunos principios o factores de éxito que ayudan a que una empresa logre traspasar fronteras en tiempo y en rentabilidad; es decir que no solo permanezca muchos años en el mercado, sino que además se mantenga en constante crecimiento y rentabilidad.

Label space reduction in GMPLs and All-Optical Label Swapping networks

All-Optical Label Swapping (AOLS) es una tecnología clave para la implementación de nodos de conmutación completamente óptica de paquetes. Sin embargo, el costo de su desarrollo es proporcional al tamaño del espacio de etiquetas (label space). Debido a que los principios de funcionamiento de AOLS son casos particulares de los del MultiProtocol Label Switching (MPLS), esta tesis estudia métodos generales, aplicables a ambos, con el propósito de reducir el espacio de etiquetas tanto como sea posible. Modelos de programación lineal entera y heurísticas son propuestos para el caso en el que se permite apilar una etiqueta extra. Encontramos que cerca del 50% del espacio de etiquetas puede ser reducido, si se permite colocar una etiqueta extra en la pila. Además, particularmente para AOLS, encontramos que se puede reducir el espacio de etiquetas cerca al 25% si se duplica la capacidad de los enlaces y se permite re-encaminar el tráfico.

Interoperability for eLearning Service Management and Provision

Learning Objects offer flexibility and adaptability for users to request personalised information for learning. There are standards to guide the development of learning objects. However, individual developers may customise these standards for serving different purposes when defining, describing, managing and providing learning objects, which are normally stored in heterogeneous repositories. Barriers to interoperability hinder sharing of learning services and subsequently affect quality of instructional design as learners expect to be able to receive their personalised learning content. All these impose difficulties to the users in getting the right information from the right sources. This paper investigates the interoperability issues in eLearning services management and provision and presents an approach to resolve interoperability at three levels.

Imagining migration: Placing children's understanding of 'moving house' in Malawi and Lesotho

Research pertaining to children's geographies has mainly focused on children's physical experiences of space, with their 'imagined geographies' receiving far less attention. The few studies of children's imagined geographies that exist tend to focus on children's national identities and their understanding of distant places. However, children's lives are not necessarily static and they often move between places. Research has not so far considered children's images of these transitional spaces or how such images are constructed. Through an examination of over 800 thematic drawings and stories, regarding 'moving house, produced by children aged 10-17 years in urban and rural communities of Lesotho and Malawi, this paper explores southern African children's representations of migration. The research considers how ideas of migration are culturally-constructed based on notions of family, home and kinship, particularly in relation to the fluid family structure characteristic of most southern African societies. The results suggest that most children imagine migration as a household rather than an individual process.. rarely including micro -migrations between extended family households in their drawings. Further, children's images of migration are place-rooted in everyday life experiences. Their representations concentrate on the reasons for migration, both negative and positive, which are specifically related to their local social and environmental situations and whether house moves take place locally or over longer distances. The paper concludes by exploring the implications of these conceptualisations of moving house for children's contemporary migration experiences, particularly in light of changing family structures due to the effects of the HIV/AIDS pandernic.
