Dans une démarche inspirée des sciences de la nature, le behaviorisme logique se présente comme une théorie philosophique visant à rendre compte des états mentaux de façon « objective », en réduisant ceux-ci au comportement observable. Comme l’énonçait déjà Hempel, il s’agit de traduire tout énoncé psychologique en un énoncé où ne figurent plus que des concepts physiques de façon à faire l’économie de la dimension subjective de l’expérience, laquelle ne constituerait rien de plus qu’un simple rouage à vide, inessentiel à l’état mental lui-même. Dans cet article, je propose d’examiner les principaux arguments, désormais jugés classiques, avancés par Wittgenstein, Ryle et Dennett en faveur de cette théorie. Mon but est non seulement de mettre au jour les déficiences de l’argumentation et les présupposés problématiques qui la guident, mais plus fondamentalement de montrer en quoi cette doctrine, en dépit de la popularité qu’elle s’est acquise en philosophie contemporaine, s’avère à l’analyse inconsistante.

The minimally conscious state (MCS) has been sub-categorized in MCS plus and MCS minus, i.e. respectively with and without command following capacity. Here we aimed at characterizing differences in MCS plus as compared to MCS minus by means of functional connectivity (FC). Resting state functional magnetic resonance imagery (fMRI) was acquired in 292 MCS patients and a seed-based analysis was conducted on a convenience sample of 19 MCS patients (10 MCS plus and 9 MCS minus) and 35 healthy controls. We investigated the left and right frontoparietal networks (FPN), the auditory network and the default mode network (DMN). We employed a ROI-to-ROI analysis and a voxel-based morphometry in order to investigate the inter-hemispheric connectivity and the grey and white matter volume, respectively. A significantly higher FC was found in MCS plus as compared to MCS minus in the left FPN, specifically between the left dorso-lateral prefrontal cortex and the left temporo-occipital fusiform cortex (TOFC). The FC of auditory network, right FPN and DMN, inter-hemispheric connectivity and structure of grey and white matter did not show differences between patients groups. The clinical sub-categorization of MCS is therefore sustained by FC differences in a language-related executive control network. These patient groups are not differentiated by networks involved in auditory processing, perception of surroundings and internal thoughts, nor by differences in inter-hemispheric connectivity and in morphology.

With four years of nearly-continuous photometry from Kepler, we are finally in a good position to apply asteroseismology to $\gamma$ Doradus stars. In particular several analyses have demonstrated the possibility to detect non-uniform period spacings, which have been predicted to be directly related to rotation. In the present work, we define a new seismic diagnostic for rotation in $\gamma$ Doradus stars that are too rapidly rotating to present rotational splittings. Based on the non uniformity of their period spacings, we define the observable $\Sigma$ as the slope of the period spacing when plotted as a function of period. We provide a one-to-one relation between this observable $\Sigma$ and the internal rotation, which applies widely in the instability strip of $\gamma$ Doradus stars. We apply the diagnostic to a handful of stars observed by Kepler. Thanks to g-modes in $\gamma$ Doradus stars, we are now able to determine the internal rotation of stars on the lower main sequence, which is still not possible for Sun-like stars. [less ▲]

The tomato leafminer, Tuta absoluta (Lepidoptera: Gelechiidae), is a widespread devastating pest that develops on tomato and other economically important solanaceous crops. Current semiochemically-based management strategies still fail to significantly reduce damages and need to be improved. Here we describe under scanning and transmission electron microscopy the structure and distribution of the sensilla that are displayed on adult antennae. These were similar in size between males (3424.4 ± 135.3 μm) and females (3292.1 ± 111.5 μm), being segmented into a scape, a pedicel, and a distal filiform flagellum. Eight morphological sensilla types were observed on both sexes: Böhm’s bristles, sensilla squamiformia, sensilla trichodea, sensilla basiconica (two subtypes), sensilla chaetica, sensilla coeloconica, sensilla auricillica, and sensilla styloconica. The main sexual dimorphism was related to the higher abundance of sensilla trichodea in males, twice as abundant as in females. The putative functional significance of the different sensilla types regarding the insect ecology is discussed based on the available literature. This work provides descriptions of the antennae and related sensory structures. We expect these results to help develop further electrophysiological investigations aiming to a better understanding of T. absoluta olfaction. [less ▲]

Le système belge de pension comporte des éléments de redistribution en faveur des bas revenus. Cependant, l'espérance de vie d'un individu est corrélée positivement avec ses revenus. Par conséquent, les gens avec un revenu important bénéficient généralement de leur pension de retraite pendant un nombre d'année plus important, ce qui remet potentiellement en cause le caractère redistributif du système.

Chronic colonic inflammation in ulcerative colitis (UC) may induce dysplasia, which can itself progress and transform into neoplasia. Diagnosis of dysplasia in UC remains difficult particularly when tissue inflammation is present. The aim of this retrospective pilot study was to highlight proteins specifically associated with inflammation induced dysplasia in UC. We performed a pilot experiment on 15 Formalin-Fixed, Paraffin-Embedded (FFPE) samples isolated from 5 cases of UC patients with a Polypoïd Pedunculated dysplasia (UC-PP). We compared the proteomes of the UC-PP, the inflammatory (UC-I) and the normal (UC-NL) tissues of each patient. We performed Laser Capture Microdissection (LCM) in order to collect only epithelial cells, avoiding inflammatory infiltrating ones. Label free proteomic analysis using a 2D-nanoUPLC coupled with a hybrid Quadrupole-Orbitrap was applied, as well as differential analysis on the paired samples. Immunohistochemistry (IHC) characterisation of one of the selected proteins of interest was used for validation. Out of 985 quantified proteins, 7 were found significantly more abundant in UC-PP compared to UC-I tissues, with 6 being only detected in UC-PP using proteomics. One of these is Solute Carrier Family 12 member 2 (SLC12A2), also known as Na-K-2Cl co-transporter 1 (NKCC1), a protein involved in ionic balance, in T-cell migration promotion and in some features involved in cancer development like proliferation, migration or invasion. IHC results obtained were in correlation with proteomic results and showed that SLC12A2 was more abundant in UC-PP tissue than in UC-I and UC-NL tissues, with a signal clearly delimiting the dysplastic region from the surrounding inflammatory tissue. This pilot experiment shows a different proteomic profile in inflammation-associated dysplasia and simple inflammation. This should be replicated using other types of dysplasia in IBD. SLC12A2 could be a potential biomarker of inflammation-associated dysplasia. [less ▲]

Social media are now essential platforms for marketing communications, and the volume of consumer-brand in- teractions on these platforms is exploding. Even so, it remains unclear how brands should communicate with consumers to foster relationships and, in particular, to gain their trust. A fundamental decision in this regard is the choice of a communication style, specifically, whether an informal or a formal style should be used in social media communications. In this paper, we investigate how adopting an informal (vs. formal) communication style affects brand trust and demonstrate that using an informal style can either have a positive or negative effect on brand trust, depending on whether consumers are familiar with the brand or not. We further show that these ef- fects occur because consumers expect brands to behave according to social norms, such that the use of an infor- mal style is perceived to be appropriate for familiar brands and inappropriate for unfamiliar ones.
