Trade, innovation and interdependence : a spatial econometric approach

2015

This thesis studies the consequences for innovation of international trade allowing for spatial interdependence. Indeed, the mechanisms through which international trade affects innovation are based on highlighting factors that, because they are the source of increasing returns, represent real engines of the growth. Yet, the accumulation process of these factors depends on effects which are constraints in space .First, trade flows by which technology is supposed to transmit between countries are interdependent. Second, the results highlighted in existing literature capture only the direct effect of trade on innovation. However, it is possible that a country benefits technology from an anoth…

The spectrum of weakly coupled map lattices

1998

We consider weakly coupled analytic expanding circle maps on the lattice Zd (for d 2 l), with small coupling strength c and coupling between two sites decaying exponentially with the distance. We study the spectrum of the associated (Perron-Frobenius) transfer operators. We give a FrCchet space on which the operator associated to the full system has a simple eigenvalue at 1 (corresponding to the SRB measure p* previously obtained by Bricmont-Kupiainen (BKl)) and the rest of the spectrum, except maybe for continuous spectrum, is inside a disc of radius smaller than one. For d = 1 we also construct Banach spaces of densities with respect to pr on which perturbation theory, applied to the diff…

La décomposition canonique et la cointégration

1994

This paper has introduced state space models for cointegrated time series. In doing so, the notion of cointegration is slightly generalized. We develop the notion of dynamic aggregation link with error correction model and common trends.

One Phase Commit: A Low Overhead Atomic Commitment Protocol for Scalable Metadata Services

2012

As the number of client machines in high end computing clusters increases, the file system cannot keep up with the resulting volume of requests, using a centralized metadata server. This problem will be even more prominent with the advent of the exascale computing age. In this context, the centralized metadata server represents a bottleneck for the scaling of the file system performance as well as a single point of failure. To overcome this problem, file systems are evolving from centralized metadata services to distributed metadata services. The metadata distribution raises a number of additional problems that must be taken into account. In this paper we will focus on the problem of managi…

Iconography and monumental art in "feodal space" from the 10th to the 12th century : the depiction of the Three Kings and its spread

2012

This dissertation deals with the iconography of the Three Kings from the Xth to the XIIth century, by means of a study of its adaptation on monumental decoration in Latin Europe, so as to unravel how it was adapted by feudal society. In order to do so, the first question is that of the new royal status acquired in the Xth century by the Magi from the Gospel of Matthew, analyzed thanks to the concept of “ruler figure” that emerged at the time and was depicted by Marc Bloch in Les Rois thaumaturges (1924) and Ernst Kantorowicz in the The King’s Two Bodies (1957). The aim is to define where the newly defined Three Kings stand in the intricate network of “ties between man and man” theorized by …

Espaces du quotidien et dynamiques de l’altérité pendant le confinement

2022

This study is the first result of the research entitled "Mon Espace Vécu" (My Lived Space) conducted in Italy during the first lockdown of 2020 (March-June), which was imposed by the government to contain the Covid-19 pandemic. During that period, the authors collected hundreds of textual testimonies from volunteers experiencing everyday spaces during the pandemic. The reflection, conducted from the perspective of cultural geography and cultural anthropology, develops from the analysis of some of these testimonies. Specifically, this paper focuses on the forms of semantization of space and the relationship between the body, space, and dynamic identity/otherness.

Culture et patrimoine dans les municipalités : une communication politique en quête de consensus ? : enjeux démocratiques des questions culturelles e…

2017

This research falls mainly into the field of political communication. It tries to comprehend cultural and patrimonial questions as essentiel political communication issue in the municipalities in France. Having chosen two fields (Nice and Dijon), established a theoretical tool and a methodology, we started to hypothesize as follows : the political communication, relating to matters of culture and heritage in the local democratic life, builds up as two differing communication systems in each city. Our work draws on a corpus composed of semi-structured interviews with elected representatives, their speeches and other additional sources (speeches in the media, public and private archives of th…

L’Horta, agricultura y ciudad: historia y presente. Valencia capital mundial de la alimentación en 2017 / L’Horta, agriculture and city: history…

2018

La produccion agraria en fresco para el consumo de proximidad se plantea como una opcion para el mantenimiento de la Huerta como paisaje unico y como una estrategia complementaria de desarrollo (Especializacion Inteligente). El nuevo plan subregional de ordenacion del territorio de la Huerta de Valencia, y la ley que lo acompana, ponen en primer plano la recuperacion del valor productivo de este espacio como parte de la nueva Infraestructura Verde. En el articulo estas cuestiones se ponen en relacion con la declaracion de Valencia como capital mundial de la alimentacion; un ejemplo de «reconversion» de la estrategia de grandes eventos del pasado, pero con una orientacion diametralmente opue…
