Theoretical approaches for geometric optimization of urban forms : towards a fractal development of the city
2017
This thesis aims to establish a urban structure that optimizes inhabitant's preferences. In other words, we want to find out which city shape answers the best the residents' aspirations, according to their consumption preferences for urban and green amenities. By considering a theoretical field of study and by characterizing the population by a Cobb-Douglas behavioral pattern, we will build step by step a city, assuming successive arrivais of new individuals, in order to find out which geometric shape gives the most suitable answer. The final goal of this thesis is there to suggest a city with a fractal shape as an appro- priate answer to the resident's expectations. We will show that this …
La valeur de la proximité pour une nouvelle interface métabolique
2016
La proximité constitue le noeud conceptuel de la première loi de la géographie de Tobler qui affirme que « tout interagit avec tout, mais deux objets proches ont plus de chance de le faire que deux objets éloignés ». Le concept de proximité ne s’arrête donc pas à une notion purement géographique, mais il acquiert une autre dimension lorsqu’il révèle la composante qualitative des relations au niveau matériel et humain. Bailly (1998) estime que la “proximité” est une condition essentielle pour raccourcir les distances sociales, économiques et culturelles, afin de réduire les tensions et maximiser les interactions entre les acteurs territoriaux.
Interactions, spillovers de connaissance et croissance des villes européennes. Faut-il préférer la géographie, le climat institutionnel ou les réseau…
2013
Knowledge spillovers within urban economies are also sources of spillovers between cities. We examine how knowledge spillovers influenced the economic growth of 82 European metropolises over the 1990-2005 period. We model knowledge spillovers between cities on the basis of five specific interaction patterns based on geography, networks of multinational firms in advanced services, institutional climate and two combinations of these factors. Spatial models are estimated to detail the effects of growth factors in terms of spillovers and externalities. We show that spillovers are local rather than global and that interactions among cities accelerate the convergence process based on gross value …

Coping with the costs of car dependency : A system of expedients used by low-income households on the outskirts of Dijon and Paris
2018
International audience; Living on low incomes and in a car-dependent area is often interpreted as a double burden for households, even if the two characteristics are often interdependent. While their capacity for mobility is lower, low-income households in outer suburban areas are nonetheless mobile. Their capacities in this domain should not be underestimated or overlooked. They can command a set of alternative practices or expedients to deal with car-related economic stress by a set of resources derived essentially from spatial proximity. This article aims to present and analyse the diversity of these expedients for the case of outer suburban areas around Paris and Dijon. The analysis of …
VILMODes, Ville et mobilité durables, évaluation par la simulation
2014
Dans le contexte actuel de vulnérabilité des systèmes urbains fondés sur la mobilité automobile, il devient crucial d’anticiper les relations entre mobilité et localisation des espaces résidentiels. Sur cette question, un débat controversé s’est installé à propos des stratégies de transport et d’urbanisation. De nombreux auteurs ont pointé la périurbanisation du doigt et proposé un retour à une ville compacte et dense qui favoriserait l’utilisation des transports publics et permettrait une bonne accessibilité aux aménités, en même temps qu’elle réduirait la ségrégation sociale. D’autres auteurs ont par contre émis des doutes en montrant que la ville compacte a souvent pour corollaire un ris…

Depression and obesity, data from a national administrative database study: Geographic evidence for an epidemiological overlap
2019
BackgroundDepression and obesity are two major conditions with both psychological and somatic burdens. Some data suggest strong connections between depression and obesity and more particularly associated prevalence of both disorders. However, little is known about the geographical distribution of these two diseases. This study aimed to determine if there is spatial overlap between obesity and depression using data from the entire French territory.MethodsData for 5,627 geographic codes for metropolitan France were collected from the two national hospital databases (PMSI-MCO and RIM-P) for the year 2016. We identified people who were depressed, obese or both registered in the two public medic…
