A supposer que le concept de valeur soit un concept empirique, qui a sa source dans l'expérience, de quel type est l'expérience de la valeur? Dans les pages suivantes, je suggère qu’Ehrenfels et Meinong ont apporté certaines améliorations substantielles à la position de Brentano. Ces améliorations résident essentiellement dans les deux points suivants : (1) les volitions se caractérisent par une dimension « active » ou conative qui fait défaut aux sentiments, ce qui interdit de les ranger dans une seule et même « classe » de phénomènes psychiques ; (2) le concept de valeur trouve son origine empirique dans les volitions ou les phénomènes conatifs, non dans les sentiments ou phénomènes affectifs.

Diffusion kurtosis imaging (DKI) is a promising extension of diffusion tensor imaging, giving new insights into the white matter microstructure and providing new biomarkers. Given the rapidly increasing number of studies, DKI has a potential to establish itself as a valuable tool in brain diagnostics. However, to become a routine procedure, DKI still needs to be improved in terms of robustness, reliability, and reproducibility. As it requires acquisitions at higher diffusion31 weightings, results are more affected by noise than in diffusion tensor imaging. The lack of standard procedures for post-processing, especially for noise correction, might become a significant obstacle for the use of DKI in clinical routine limiting its application. We considered two noise correction schemes accounting for the noise properties of multichannel phased-array coils, in order to improve the data quality at signal-to-noise ratio (SNR) typical for DKI. The SNR dependence of estimated DKI metrics such as mean kurtosis (MK), mean diffusivity (MD) and fractional anisotropy (FA) is investigated for these noise correction approaches in Monte Carlo simulations and in in vivo human studies. The intra-subject reproducibility is investigated in a single subject study by varying the SNR level and SNR spatial distribution. Then the impact of the noise correction on inter-subject variability is evaluated in a homogeneous sample of 25 healthy volunteers. Results show a strong impact of noise correction on the MK estimate, while the estimation of FA and MD was affected to a lesser extent. Both intra- and inter-subject SNR related variability of the MK estimate is considerably reduced after correction for the noise bias, providing more accurate and reproducible measures. In this work, we have proposed a straightforward method that improves accuracy of DKI metrics. This should contribute to standardization of DKI applications in clinical studies and making valuable inferences in group analysis and longitudinal studies. [less ▲]

From both a scientific and a practical point of view, two major trends seem to presently rule the adult training field: the psychosociological trend and the ergonomic trend. Though each one has widely contributed in developing training in organizational human resources development, we fail to see any significant level of understanding between the two trends or any dialogue based on scientific objectivity. The aim of this present paper is to hopefully initiate a dialogue with an eye towards development in training practices. A better understanding of these main approaches would bring help to those who seek to train personnel and to better orientate their choice of training. [less ▲]

Although mobility management by employers is an increasingly common practice, literature is scarce on the real impact of the applied measures. In this perspective, the objective of this paper is to assess the impact on car use of the measures adopted by employers located in Wallonia. In order to achieve this objective, the article develops simulations that put forward the impact of the measures based on their interrelations with other modal choice factors. Our assessment leads to the conclusion that measures promoting public transport and car-pooling can reduce solo car driving between 7,2 % and 8,4 %. In contrast to our assumption, measures promoting public transport are less effective in central areas than in urban outskirts. Regarding measures promoting the use of bicycle, the findings suggest that the modal shift occurs from other modes rather than from car use. [less ▲]

Objectives: Patients with locked-in syndrome often self-report a higher quality of life than generally expected. This study reports third-person attitudes towards several salient issues on locked-in syndrome. Methods: Close-ended survey among conference attendees from 33 European countries. Analysis included chi-square tests and logistic regressions. Results: From the 3332 respondents (33% physicians, 18% other clinicians, 49% other professions; 47% religious), 90% agreed that patients with locked-in syndrome can feel pain. The majority (75%) disagreed with treatment withdrawal, but 56% did not wish to be kept alive if they imagined themselves in this condition (p50.001). Religious and southern Europeans opposed to treatment withdrawal more often than non-religious (p50.001) and participants from the North (p¼0.001). When the locked-in syndrome was compared to disorders of consciousness, more respondents endorsed that being in a chronic locked-in syndrome was worse than being in a vegetative state or minimally conscious state for patients (59%) than they thought for families (40%, p50.001). Conclusions: Personal characteristics mediate opinions about locked-in syndrome. The dissociation between personal preferences and general opinions underlie the difference in perspective in disability. Ethical responses to dilemmas involving patients with locked-in syndrome should consider the diverging ethical attitudes of stakeholders. [less ▲]

When nodules of lime are embedded into concrete, the expansion accompanying the transformation of CaO into Ca(OH)2 induces stresses and strains in both the lime nodule and in the concrete matrix. The concrete cover thickness, the diameter and the shape of the lime nodule as well as the mechanical characteristics of concrete and lime are the key parameters influencing the development of internal pressure and hence controlling the risk of cracking or pop-out. In order to study the effect of lime into cementitious concretes, laboratory investigations and modelling have been performed and show that the minimum cover thickness necessary to avoid the development of the pop-out phenomenon is estimated of the order of half the diameter of the inclusion. This is coming from the observation that expansion happens inside the porosity of the hydrated lime Ca(OH)2: ESEM and DRX analysis confirm the effect of confinement in the development of crystals.

This paper considers a trajectory-based approach to determine control signals superimposed to those of existing controllers so as to enhance the damping of electromechanical oscillations. This approach is framed as a discrete-time, multi-step optimization problem which can be solved by model-based and/or by learning-based methods. This paper proposes to apply a model-free tree-based batch mode Reinforcement Learning (RL) algorithm to perform such a supplementary damping control based only on information collected from observed trajectories of the power system. This RL-based supplementary damping control scheme is first implemented on a single generator and then several possibilities are investigated for extending it to multiple generators. Simulations are carried out on a 16-generators medium size power system model, where also possible benefits of combining this RL-based control with Model Predictive Control (MPC) are assessed.

L'immense espace géographique qui va de la Terre de Feu au Sud du Texas et des côtes du Chili aux Petites Antilles fut le théâtre d'une histoire marquée par d’incessants mouvements migratoires qui débutèrent au XVIe siècle avec la colonisation. La diversité et l’ampleur de ces flux d'hommes de toutes races, de toutes provenances et de toutes croyances ont été à l'origine de phénomènes d'acculturation complexes et variés. Les musiques indigènes, européennes et africaines ont été réinterprétées, recréées pour aboutir à des formes inédites variant selon les régions ou le degré d’influence de chacune des sources. Ce vocabulaire est destiné à donner un aperçu de cette immense richesse et à éclairer le public francophone sur ces traditions musicales qui, pour certaines, se sont largement diffusées. [less ▲]

La scène du télégraphe optique, dans Le Comte de Monte-Cristo, aide à mettre en lumière la modernité du roman. Cette modernité tient pour une part à une ligne de continuité établie entre chronique judiciaire et fable romanesque, sur fond de réseau télégraphique. Elle tient plus encore au fait que cet épisode du télégraphe rend singulièrement visible l’allégorie de la communication que le roman développe à différents niveaux de sa construction narrative, allant de son incipit très sémiologique à la « voile blanche » qui signalera sur fond d’azur méditerranéen, quatorze cents pages plus loin, le départ d’un Monte-Cristo ayant recouvré son identité perdue, en passant par les deux figures successivement incarnées par son héros, dépeint en victime sacrificielle puis en expert d’une communication dont il saura jouer de tous les ressorts — rapidité de déplacement, contrôle de l’information, maîtrise des formes spéculatives et fiduciaires de l’économie, dévoiement des formes anthropologiques de l’échange social, etc. — pour l’emporter finalement sur les trois pouvoirs coalisés de la Politique (Morcerf), de la Justice (Villefort) et de la Banque (Danglars) ; tout cela orchestré par une triple métaphore du sang, de l’argent et de l’information, dont la signification réversible ne peut être séparée d’une doctrine saint-simonienne que Dumas à la fois relaie et révoque. De même que le couloir de communication établi au château d’If entre la cellule de Dantès et celle de Faria, la scène du télégraphe fait ainsi office de point de cristallisation d’une symbolique diffuse. Cette scène si cardinale, il s'agit ici de montrer qu’elle est non seulement grosse encore de tout un savoir à dimension technique autant qu’anthropologique, mais également porteuse, vers d’autres zones du roman, d’une assez étonnante préfiguration du télégraphe électrique, en cheville avec une modernité technique dont Dumas faufile les signes de façon plus ou moins cryptée dans la trame de son roman.
