La linguistique des grammaires françaises publiées en Espagne dans la première moitié du XIXe siècle
2005
RésuméDans cet article, nous examinons un corpus de 13 grammaires pour l’enseignement du français aux Espagnols, éditées dans la première moitié du XIXe siècle. Nous prenons en compte, dans une analyse de type transversal, (1) les sources citées par les auteurs ; (2) la nature de la définition de la grammaire et le nombre des parties du discours ; (3) la définition du nom (avec la présence ou non du schéma canonique de la déclinaison ou des classes spécifiques de cet élément) ; (4) la définition du verbe avec la présence ou non des catégories canoniques) ; et (5) la syntaxe. Notre objectif est de déterminer la linguistique explicite et implicite de ces grammaires scolaires, à une époque où …
Intercultural Listening: Measuring Listening Concepts with the LCI-R
2016
Listening is an integral part of communication, yet more research is conducted on the speaker as opposed to the listener. Previous research established a general schema of listening as a concept-driven behavior with four factors (Imhof & Janusik, 2006). Further testing by Bodie (2010) confirmed the factor structure and reduced the number of items from 33 to 15 (LCI-R). What is not known is whether the constructs are consistent across cultures. This study investigates whether the LCI-R can fit independent data comprising samples from the United States, Europe, and Japan. Results show that the instrument can be used cross-culturally when listening concepts are of interest and need to be measu…
Body schema plasticity after stroke: subjective and neurophysiological correlates of the rubber hand illusion
2017
[EN] Stroke can lead to motor impairments that can affect the body structure and restraint mobility. We hypothesize that brain lesions and their motor sequelae can distort the body schema, a sensorimotor map of body parts and elements in the peripersonal space through which human beings embody the reachable space and ready the body for forthcoming movements. Two main constructs have been identified in the embodiment mechanism: body-ownership, the sense that the body that one inhabits is his/her own, and agency, the sense that one can move and control his/her body. To test this, the present study simultaneously investigated different embodiment subcomponents (body-ownership, localization, an…
Biased postural vertical in humans with hemispheric cerebral lesions.
1998
International audience; This study was aimed at demonstrating the existence of a biased postural vertical in humans with a recent cerebral lesion. The postural vertical of patients and controls was analysed comparatively using a self-regulated balancing task, performed in sitting posture. Patients displayed a quite constant (19/22) contralesional tilt of the postural vertical (mean -2.6 degrees), varying with the severity of their spatial neglect and hemianaethesia. Eight of them showed a pathological contralesional bias (mean -5.5 degrees) as compared to normals. This result indicates an asymmetric process of somatic graviceptive information due to some cerebral lesions. When patients were…
Far Space Remapping by Tool Use: A rTMS Study Over the Right Posterior Parietal Cortex
2015
Abstract Background In previous studies, rTMS has been successfully employed to interfere with the right posterior parietal cortex (rPPC) inducing neglect-like behavior in healthy subjects. Several studies have shown that the use of tools can modulate the boundaries between near and far space: indeed when far space is reached by the stick, far space can be remapped as near. Objective The aim of the present study was to investigate whether once that rTMS on the rPPC has selectively induced neglect-like bias in the near space (but not in the far space), neglect can appears also in the far space when the subjects used a tool to perform the task. Methods Fifteen right-handed healthy subjects ex…
Online Metric Learning Methods Using Soft Margins and Least Squares Formulations
2012
Online metric learning using margin maximization has been introduced as a way to learn appropriate dissimilarity measures in an efficient way when information as pairs of examples is given to the learning system in a progressive way. These schemes have several practical advantages with regard to global ones in which a training set needs to be processed. On the other hand, they may suffer from a poor performance depending on the quality of the examples and the particular tuning or other implementation details. This paper formulates several online metric learning alternatives using a passive-aggressive schema. A new formulation of the online problem using least squares is also introduced. The…
An empirical study of recommendations in OLAP reporting tool
2015
This paper presents the results of the experimental study that was performed in laboratory settings in the context of the OLAP reporting tool developed and put to operation at the University. The study was targeted to explore which of the modes for generating recommendations in the OLAP reporting tool has a deeper impact on users (i.e. produces more accurate recommendations). Each of the modes of the recommendation component â report structure, user activity, and semantic â employs a separate content-based method that takes advantage of OLAP schema metadata and aggregate functions. Gained data are assessed (i) quantitatively by means of the precision/recall and other metrics from the lo…
Dimension enrichment with factual data during the design of multidimensional models: application to bird biodiversity
2015
20 pages; International audience; Data warehouses (DW) and OLAP systems are technologies allowing the on-line analysis of huge volume of data according to decision-makers’ needs. Designing DW involves taking into account functional requirements and data sources (mixed design methodology) [1]. But, for complex applications, existing automatic design methodologies seem inefficient. In some cases, decision-makers need querying, as a dimension, data which have been defined as facts by actual automatic mixed approachs. Therefore, in this paper, we offer a new mixed refinement methodology relevant to constellation multidimensional schema. The proposed methodolgy allows to decision-makers to enric…
Relativistic Versus Nonrelativistic ΛN Correlations in the Weak Decay of Hypernuclei
1995
We establish the reasons for the different effect of short range correlations in the nonmesonic decay of Λ hypernuclei found by relativistic and nonrelativistic approaches. By means of a schematic microscopic model for the origin of correlations, the appropriate method to include them in nuclear processes, via a correlation function, is derived and is found to be the one used in the nonrelativistic approach.
Defining Components in a MetaCASE Environment
2000
In this paper we describe how to improve method reusability in a metaCASE environment called MetaEdit+. The suggested component based approach helps unify design artefacts into components with explicit interfaces and meaningful context descriptions. We describe a method artefact from three perspectives: concept, content, and context. We create a component concept by using a hierarchical facet-based schema, and represent contextual relationship types by using definitional and reuse dependency, usage context, and implementation context links. This is the first attempt to explicitly define components into a metaCASE environment.
