Preserved Crossmodal Integration of Emotional Signals in Binge Drinking
2017
Binge drinking is an alcohol consumption pattern with various psychological and cognitive consequences. As binge drinking showed qualitatively comparable cognitive impairments to those reported in alcohol-dependence, a continuum hypothesis suggests that this habit would be a first step toward alcohol-related disorders. Besides these cognitive impairments, alcohol-dependence is also characterized by large-scale deficits in emotional processing, particularly in crossmodal contexts, and these abilities have scarcely been explored in binge drinking. Emotional decoding, most often based on multiple modalities (e.g., facial expression, prosody or gesture), yet represents a crucial ability for eff…
Frontal Electroencephalogram Alpha Asymmetry during Mental Stress Related to Workplace Noise
2021
This study aims to investigate the effects of workplace noise on neural activity and alpha asymmetries of the prefrontal cortex (PFC) during mental stress conditions. Workplace noise exposure is a pervasive environmental pollutant and is negatively linked to cognitive effects and selective attention. Generally, the stress theory is assumed to underlie the impact of noise on health. Evidence for the impacts of workplace noise on mental stress is lacking. Fifteen healthy volunteer subjects performed the Montreal imaging stress task in quiet and noisy workplaces while their brain activity was recorded using electroencephalography. The salivary alpha-amylase (sAA) was measured before and immedi…

Investigation of Coating Impact on OFDR Optical Remote Fiber-Based Sensors Performances for Their Integration in High Temperature and Radiation Envir…
2016
The response of optical frequency-domain reflectometry-based temperature sensors is here investigated in harsh environments (high temperature, high radiation dose) focusing the attention on the impact of the fiber coating on the sensor performances in such conditions. Our results demonstrate that the various coating types evolve differently under thermal treatment and/or radiations, resulting in a small (<5%) change in the temperature coefficient of the sensor. The identified procedure, consisting of a prethermal treatment of the fiber at its maximum coating operating temperature, is here verified up to 150 °C for higherature acrylate and up to 300 °C for polyamide coating. This method allo…
Intégrer des informations en escamots dans les textes techniques : quels effets sur les processus cognitifs ?
1998
Though computerized sytems now offer a wide range of options for accessing and displaying text or text-picture information, little is known about their effects on the user's cognitive processes. In this paper, we investigate the effect of a computer-specific display (pop-up window) which consists in displaying some pieces of information in windows that appear only under user's action. Experiments were carried out to compare the pop-up window device with other devices used on paper. The experiments dealt with text only as well as text-picture documents and involved various tasks. Results are discussed from a theoretical and a practical point of view.
Les ecclésiastiques devant le tribunal de district de Dijon sous la période révolutionnaire : l'application du gallicanisme
2008
International audience; Avec la constitution civile du clergé du 12 juillet 1790, sanctionnée le 24 août, la Constituante entend imposer son idéal politique aux ecclésiastiques. Ceux-ci, comme sous l'Ancien Régime, sont encadrés et surveillés par les autorités séculières, en particulier par les tribunaux. Aussi, l'étude des archives du tribunal de district de Dijon, statuant au civil et au pénal, apporte-t-elle de précieux compléments aux études nationales et locales, le prisme des litiges ordinaires révélant les conséquences concrètes des nouvelles règles dans la vie quotidienne des clercs. Les registres du tribunal de district de Dijon, pour la période révolutionnaire, comportent plus de …
Ergonomie des documents numériques
2001
14 pages; International audience; Le problème de l'ergonomie des documents numériques est crucial et répond à une insatisfaction fréquente des utilisateurs quant à l'usage de ce type de document. La conception de documents numériques est souvent basée sur des considérations empiriques issues des savoir-faire acquis avec le support papier. Pourtant, une abondante littérature, il est vrai dispersée dans différents champs de recherche, concerne les effets des facteurs de présentation des informations sur écran, tant au niveau perceptif qu'au niveau cognitif. Nous présentons ici une revue des principaux résultats et leurs implications concernant la conception de documents numériques. Les docume…
Skeleton-Based Multiview Reconstruction
2016
International audience; The advantage of skeleton-based 3D reconstruction is to completely generate a single 3D object from well chosen views. Having numerous views is necessary for a reliable reconstruction but projections of skeletons lead to different topologies. We reconstruct 3D objects with curved medial axis (whose topology is a tree) from the perspective skeletons on an arbitrary number of calibrated acquisitions. The main contribution is to estimate the 3D skeleton, from multiple images: its topology is chosen as the closest to those of the perspective skeletons on the set of images, which means that the number of topology changes to map the 3D skeleton topology to topologies on im…
Ergonomie des documents techniques informatisés : expériences et recommandations sur l'utilisation des organisateurs para-linguistiques
1998
Despite an increasing development, the design of computerized documents is still based on intuitive or esthetics concerns, rather than on experimental evidence. However a large body of literature has investigated the effects of various display factors, both on a perceptual and on a cognitive level. We propose here a review of research and its implication on the design of computerized documents.
