Within the quick nano-fabrication techniques evolution and the increasing needs in low space and energy opto-electronic functions on-chip integration, studies and control of electromagnetic resonances of sub-micrometric objects are crucial issues. One aim of this work was then to improve our knowledge of the light-matter interaction. To this end, optical near-field experiments and complementary numerical development of models have been performed to study electromagnetic resonances due to light-matter interaction in sub-micrometric resonators. As an introduction, the first part of the manuscript presents the main phenomena involved in near-field optical microscopy and the used SNOM operation…
Mesures, développement : le statut de la créativité en question
2016
Les particularités inhérentes à la créativité en tant que compétence transversale, analysées à partir d’une revue de littérature en psychologie et sociologie sur la mesure, le développement et les effets de la créativité, semblent lui conférer un statut restreint au sein du système éducatif français. D’une part, les incertitudes autour des effets à long terme de la créativité, tout comme la logique adéquationniste structurant l’organisation scolaire, maintiennent cette compétence à l’écart des principales finalités assignées au système éducatif français. D’autre part, celui-ci n’est pas outillé pour la mesurer, étant donné que ses méthodes d’évaluation ne permettent pas d’appréhender cette …
La vulgarisation scientifique et les doctorants : mesure de l'engagement, exploration d'effets sur le chercheur
2018
We ask two questions: what are the factors that influence researchers’ public engagement activities (PEA)? And what are the impacts of these activities on the researcher? After presenting a historical overview of PEA, we analyze 20 surveys carried out between 1967 and 2014. We identify some global trends: PEA is generally positively perceived, researcher’s engagement is occasional but robust. Besides those trends some differences appear between studies based on theoretical models and empirical studies: the latter report complaints such as lack of time or lack of recognition, whereas theoretical-based ones challenge these statements.To further explore our two questions, we used two approache…
Essay on the integration of interactions in the treatment effect evaluation : the contribution of spatial econometrics methods
2015
This thesis focuses on the integration of interactions in the estimation of the public policy’s effect. Indeed, the estimation standard methods usually rely on strong assumptions that exclude partially or completely the interaction effect both in the selection process of beneficiaries and in the performance of the policy. However, the validity of these assumptions is questionable, particularly in the context of a non-experimental policy because an individual according as it is the beneficiary or not the policy, is not isolated: he interacts with his neighborhood. Thus, the estimated effect of the policy by traditional methods is likely to be biased (underestimation or overestimation) theref…
Photo-thermal control of surface plasmon mode propagation at telecom wavelengths
2016
Surface plasmon polaritons (SPPs) is the promising versatile platform proposed for guiding electromagnetic waves at nanoscale dimensions. In this context dynamic control of SPPs prop- agation is of paramount importance. Thermo-optical (TO) effect is considered as an efficient technique for performing active control of plasmonic devices. Among the thermo-optical based plasmonic devices demonstrated so far TO coefficient is dominantly provided by a dielectric material on top of the metal sustaining the SPP mode, however, the role of TO properties of the metal has been rarely investigated for plasmonic applications especially at the telecom frequency ranges. Therefore, the aim of this thesis i…
L’appropriation territoriale des nouvelles gares TGV périphériques françaises au miroir des SCOT (Schéma de Cohérence Territoriale)
2019
International audience; Face à la grande diversité des dynamiques territoriales liées à la grande vitesse ferroviaire et aux difficultés rencontrées pour isoler l’influence de la nouvelle offre de transport des autres facteurs intervenant dans les évolutions socio-économiques et spatiales des territoires, les chercheurs s’attachent désormais davantage à la compréhension des processus par lesquels naissent les changements territoriaux en questionnant la façon dont les acteurs territoriaux s’approprient à travers leurs comportements, leurs pratiques et leurs représentations, la nouvelle offre de transport. Comme l’ont montré de nombreux travaux, l’infrastructure et les nouvelles conditions d’…
Économétrie spatiale : l'autocorrélation spatiale dans les modèles de régression linéaire
2002
Spatial Econometrics : Automatic Spatial Correlation in Linear Regression Models. The aim of this article is to describe the tools necessary to factor in automatic spatial correlation determined by the absence of independence between geographical observations, within the framework of linear regression models. While it is often accepted that spatial data in cross-sections are independent, this assumption is rarely justified. On the contrary, it needs to be tested systematically. After explaining the ways in which to model automatic spatial correlation, we therefore describe estimation and inference procedures geared to econometric models that factor in this effect explicitly. Lastly, we prop…

NEIGHBORHOOD EFFECTS IN SPATIAL HOUSING VALUE MODELS. THE CASE OF THE METROPOLITAN AREA OF PARIS (1999)
2009
In hedonic housing models, the spatial dimension of housing values are traditionally processed by the impact of neighborhood variables and accessibility variables. In this paper we show that spatial effects might remain once neighborhood effects and accessibility have been controlled for. We notably stress on three sides of neighborhood effects: social capital, social status and social externalities and consider the accessibility to the primary economic center as describing the urban spatial trend. Using spatial econometrics specifications of the hedonic equation, we estimate whether spatial effects impact the housing values. Our empirical case concerns the Metropolitan Area (MA) of Paris i…
