Insight et schizophrénie : revue de la littérature

Abstract: Resume Objectifs Ce travail consiste en une revue de la litterature mettant en evidence les differentes conceptions et les differentes modalites d’evaluation de l’insight des patients atteints de schizophrenie qui en decoulent. Il s’agit en effet de montrer que l’insight designe un phenomene possedant de multiples facettes et dimensions. Methode Les differentes conceptions et methodes d’evaluation de l’insight seront passees en revue afin de montrer la complexite du phenomene d’insight, la difficulte qu’il y a a evaluer de facon multidimensionnelle l’insight et a mettre en lien les dimensions specifiques (clinique, cognitif, processuel) qui sont impliquees dans l’evolution (favorable, defavorable) du trouble schizophrenique et de sa prise en charge. Resultats Cette revue de la litterature met en evidence la complexite de la notion d’insight dans le cadre de la schizophrenie. L’absence de consensus dans la definition de l’insight amene a penser l’insight dans la schizophrenie comme un phenomene complexe. L’une des consequences est alors la difficulte a l’evaluer de facon standardisee. Discussion Si la conscience de la maladie apparait comme un enjeu dans la prise en charge des patients, aucun consensus ne se degage dans les effets positifs ou deleteres qu’un bon degre d’insight pourrait avoir sur le patient, son trouble et sa prise en charge. Conclusion Afin de mieux comprendre les effets de l’insight, dans un travail en cours, des patients atteints de schizophrenie a des degres divers de remission seront interroges avec des outils multidimensionnels et un entretien standardise. L’objectif sera de confronter non seulement les points de vue (experts/patients) sur ce qu’est l’insight mais aussi de determiner de quelles facons les dimensions specifiques de l’insight pourraient etre importantes dans la prise en charge des patients atteints de schizophrenie.

Forced vibration analysis of composite beams based on the variable separation method

Abstract: This paper proposes a new strategy based on the proper generalized decomposition method to solve the forced vibration problem in two-dimensional (2D) layered beams. The approach redefines the probl...

Investigating Eye Contact Effect on People's Name Retrieval in Normal Aging and in Alzheimer's Disease.

Abstract: Difficulty in recalling people's name is one of the most universally experienced changes in old age and would also constitute one of the earliest symptom of Alzheimer's disease (AD). Direct gaze, i.e., another individual's gaze directed to the observer that leads to eye contact, has been shown to improve memory for faces and concomitant verbal information. Here, we investigated whether this effect extends to memory for Face-Name association and can thus enhance names' retrieval in normal aging and in AD, at the early stage of the disease. Twenty AD patients, 20 older adults and 25 young adults participated in our study. Subjects were presented with faces displaying either direct or averted gaze in association with a name presented orally. They were then asked to perform a surprise recognition test for each pair of stimuli, in a sequential fashion (i.e., first categorizing a face as old or new and then associating a name using a forced-choice procedure). Results showed that direct gaze does not improve memory for Face-Name association. Yet, we observed an overall direct gaze memory effect over faces and names independently, across our populations, showing that eye contact enhances the encoding of concomitantly presented stimuli. Our results are the first empirical evidence that eye contact benefits memory throughout the course of aging and lead to better delimit the actual power of eye contact on memory.

Adaptive Composition and QoS Optimization of Conversational Services through Graph Planning Encoding

Abstract: Service-Oriented Computing supports description, publication, discovery, composition of services as well as QoS optimization of service composition to fulfil end-user needs. Yet, service composition processes commonly assume that service descriptions and user needs share the same abstraction level, and that services have been pre-designed to integrate. To release these strong assumptions and to augment the possibilities of composition, we add adaptation features into the service composition process using semantic structures for exchanged data, for service functionalities, and for user needs. Graph planning encodings enable us to retrieve service compositions efficiently. Our composition technique supports conversations for both services and user needs, and it is fully automated and can interact with state-of-the-art graph planning tools. In addition to service composition, QoS optimization aims at satisfying end-user needs about quality requirements. However, most existing work on QoS optimization is studied on the assumption that services are stateless. To obtain a solution with the best QoS value, we propose a QoS-aware service composition method to achieve QoS optimization during the adaptive composition over conversational services. An example is given as a preliminary proof of our QoS-aware service composition method.
