L'INFLUENCE DE L'INTRUSION PERÇUE SUR LES COMPORTEMENTS DE RÉSISTANCE AUX FORMATS DE PUBLICITÉ SUR INTERNET
2012
Drawing from the theoretical framework defined by Roux (2007), this research examines the relationship between perceived advertising intrusion (Anzieu, 1994) and manifestations of consumer resistance (Hirschman, 1970). The results show that the intrusion does not significantly affect the expression or intention to return to the website. However, it influences positively defection and negatively purchase intention of the product promoted in the ad.
L’ADULTO COME SPECCHIO. MODALITÀ COMUNICATIVE E APPRENDIMENTO
2021
Numerose ricerche sull’infanzia condotte a partire dal secolo scorso, hanno mostrato come i bambini, fin dai primi mesi di vita, siano attivi e propositivi nella interazione con gli altri esseri umani. In una prospettiva educativa, di promozione dei processi di apprendimento e di sostegno alla costruzione di una immagine di sé positiva e fiduciosa nelle proprie potenzialità, sono di grande importanza le modalità comunicative e relazionali degli adulti significativi. A tali modalità farò riferimento nel mio contributo, soffermandomi sul rispecchiamento verbale e non verbale, nelle sue diverse forme, approfondendone le ragioni teoriche e metodologiche e riflettendo su come possa attuarsi una …
L’engagement des chercheurs dans la vulgarisation scientifique
2012
International audience; Quelle attitude ont les chercheurs vis-à-vis de la vulgarisation scientifique ? Voilà une question que tout médiateur scientifique est amené à se poser. Elle intéresse aussi les gouvernements et les grandes institutions scientifiques qui incitent les chercheurs à communiquer auprès du grand public et cherchent des solutions pour améliorer cette communication.Nous avons recherché des études et des enquêtes qui, depuis 1992, auraient proposé des diagnostics sur l’attitude, l’intérêt et surtout l’engagement des chercheurs dans cette pratique de vulgarisation. Notre propos s’articulera autour d’une étude clé, publiée en 2007 par Ellen Poliakoff et Thomas L Webb qui s’int…
Villes, densité et fractalité
1995
International audience; Ce bref article résumé les résultats d'analyses fractales effectuées sur les villes françaises à plusieurs dates pour deux niveaux d'observation: les tissus urbains caractérisés par la distribution spatiale des surfaces bâties d'une part, et le semis des villes de différentes tailles dans l'ensemble du territoire français d'autre part. Les méthodes de mesure sont rapidement expliquées, l'accent est mis sur la signification des nombres obtenus, leur comparaison d'une ville à l'autre et leur évolution au cours du temps.
Nonlinear Time-Series Adaptation for Land Cover Classification
2017
Automatic land cover classification from satellite image time series is of paramount relevance to assess vegetation and crop status, with important implications in agriculture, biofuels, and food. However, due to the high cost and human resources needed to characterize and classify land cover through field campaigns, a recurrent limiting factor is the lack of available labeled data. On top of this, the biophysical–geophysical variables exhibit particular temporal structures that need to be exploited. Land cover classification based on image time series is very complex because of the data manifold distortions through time. We propose the use of the kernel manifold alignment (KEMA) method for…

L'évolution de l'occupation humaine : l'analyse spatiale exploratoire des données.Le problème de l'incertitude et de l'hétérogénéité des données en a…
2011
The analysis of the evolution of the settlement requires a lot of methodological questioning. Despite a frequent use of the spatial analysis methods, few works return to their methodological problems. This article proposes to make a comparison and a discussion around two exploratory statistical methods (the K function of Ripley and the Kernel Density Estimation). It seems that scale, quality and quantity of input data, are three essential parameters to be taken into account so as to lead a spatial analysis in archaeology. In intrinsic way, archaeological data are non homogeneous. For that purpose, our article proposes a multi scalar approach integrating the non homogeneousness character of …
Offensive Transitions in High-Performance Football: Differences Between UEFA Euro 2008 and UEFA Euro 2016
2019
[Abstract] Coaches, footballers and researchers agree that offensive transitions are one of the most important moments in football today. In a sport where defense over attack dominates, with low scores on the scoreboard, the importance of these actions from the offensive point of view becomes very important. Despite this, scientific literature is still very limited on this topic. Therefore, the objectives set out in the present investigation have been two: first, by means of a proportion analysis and the application of a chisquare test, it was intended to describe the possible differences between the offensive transitions made in the UEFA Euro 2008 and UEFA Euro 2016; then, through differen…
2015
The combination of local orientation collinearity and spatial frequency contrast in contour integration was studied in two experiments using a 2AFC contour detection and discrimination task. Target contours were defined by local orientation collinearity, spatial frequency contrast between contour and background elements, or both cues. Experiments differed in the source of spatial frequency contrast by manipulating the spatial frequency of either contour or background elements. Cue summation gains, defined as the performance benefit of double cue conditions over single cue conditions, were evaluated and tested against the predictions derived from probability summation and linear summation. S…
L'évaluation socio-économique des infrastructures de transport : enrichir les approches du développement territorial
2007
International audience; Dans les années récentes, en France, le processus décisionnel en matière de grands équipements a sensiblement évolué, débouchant sur des réponses institutionnelles en termes de procédures adaptées. Ceci a eu pour conséquence d'accroître l'exigence informationnelle destinée à alimenter les débats, éclairer les problématiques abordées, leur donner un contenu le plus objectivé possible. L'une des principales thématiques systématiquement abordées dans le cadre de ces procédures participatives, est celle du développement territorial, dont l'importance en fait un des éléments essentiels de l'acceptabilité sociale. Les enseignements des observatoires socio-économiques autor…
