L'adolescent face à la relation d'emprise scolaire : entre adaptations secondaires et arrangements ordinaires
2009
L’article etudie l’hypothese d’un desir d’emprise au cœur de toute relation pedagogique, et la relation d’emprise, quelle que soit la modalite qu’elle revet, represente une veritable formation defensive, permettant d’occulter le manque devoile par la rencontre de l’autre. De ce scenario, se degagent des regles communes a toutes les relations d’emprise : l’instrumentalisation de l’autre et l’impossibilite pour celui-ci de rompre le cycle d’echange dans lequel il donne plus qu’il ne prend, la rupture etant construite comme de l’ordre de l’injustifiable et supposant un passage en force, un acte de rebellion ou de violence. Comment les adolescents se maintiennent-ils comme sujets desirants dans…
The “chimney forest” of the deep Montenegrin margin, south-eastern Adriatic Sea
2015
A spectacular field of columnar carbonates has been discovered on the Montenegrin margin in the southern Adriatic Sea at a depth of about 450 m. The site exposes many columnar carbonates protruding from the substrate or abated on the bottom. Such carbonates attain maximum visible lengths of ca. 60 cm with diameters up to 20 cm; display an annular growth, and are either hollow or plugged by indurated sediment. Petrographic and geochemical analyses document the pervasive presence of dolomite, and delta C-13 values as low as -30%(0) VPDB. These 'chimneys' are therefore interpreted as former conduits related to hydrocarbon expulsion in this sector of the Adriatic basin. However, available data …
Transdiagnostic dimensions of psychopathology at first episode psychosis: findings from the multinational EU-GEI study.
2019
Background\ud The value of the nosological distinction between non-affective and affective psychosis has frequently been challenged. We aimed to investigate the transdiagnostic dimensional structure and associated characteristics of psychopathology at First Episode Psychosis (FEP). Regardless of diagnostic categories, we expected that positive symptoms occurred more frequently in ethnic minority groups and in more densely populated environments, and that negative symptoms were associated with indices of neurodevelopmental impairment.\ud \ud Method\ud This study included 2182 FEP individuals recruited across six countries, as part of the EUropean network of national schizophrenia networks st…
A genome-wide association study identifies two loci associated with heart failure due to dilated cardiomyopathy
2011
Dilated cardiomyopathy (DCM) is a major cause of heart failure with a high familial recurrence risk. So far, the genetics of DCM remains largely unresolved. We conducted the first genome-wide association study (GWAS) to identify loci contributing to sporadic DCM.One thousand one hundred and seventy-nine DCM patients and 1108 controls contributed to the discovery phase. Pools of DNA stratified on disease status, population, age, and gender were constituted and used for testing association of DCM with 517 382 single nucleotide polymorphisms (SNPs). Three DCM-associated SNPs were confirmed by individual genotyping (P5.0 10(-7)), and two of them, rs10927875 and rs2234962, were replicated in ind…
Constraints representing a meta-stable régime facilitate exploration during practice and transfer of learning in a complex multi-articular task
2018
Previous investigations have shown that inducing meta-stability\ud in behavior can be achieved by overlapping affordances through constraint\ud manipulation, allowing cooperative and competitive tendencies to\ud functionally coexist. The purpose of this paper was to test a number of\ud conditions applying these design principles on performance during skills\ud practice and transfer. Of additional interest, was whether the existing\ud skill level interacted with the environmental properties of the\ud experimental tasks (varying indoor climbing routes). Two skill groups\ud practised on three routes per session over four separate sessions. At the\ud end of the final session, climbers undertook…
Three-Factor Structure of Adult Attachment in the Workplace: Comparison of British, French, and Italian Samples
2014
The goal was to compare three-factor and two-factor solutions and construct validity of the Adult Attachment in the Workplace (AAW) questionnaire. Participants were 660 volunteers from three countries (France, Italy, and Great Britain). The two-factor model of Neustadt, Chamorro-Premuzic, & Furnham (2006) and the three-factor theoretical model of Collins and Read (1990) were compared. Construct validity was assessed by calculating correlations among the two- and three-factor AAW, the Workplace Attachment Scale, and the Organizational Commitment Scale. The three-factor structure differentiated between the three attachment styles, i.e., secure, preoccupied, and avoidant. There were modera…
What is French for déjà vu? Descriptions of déjà vu in native French and English speakers
2015
Little is known about how people characterise and classify the experience of deja vu. The term deja vu might capture a range of different phenomena and people may use it differently. We examined the description of deja vu in two languages: French and English, hypothesising that the use of deja vu would vary between the two languages. In French, the phrase deja vu can be used to indicate a veridical experience of recognition - as in "I have already seen this face before". However, the same is not true in English. In an online questionnaire, we found equal rates of deja vu amongst French and English speakers, and key differences in how the experience was described. As expected, the French gro…
Between a Rock and Hard Place: Combined Effects of Authentic Leadership, Organizational Identification, and Team Prototypicality on Managerial Prohib…
2019
AbstractManagers are installed by the organization’s stakeholders and shareholders to increase the organization’s value; at the same time, they depend on their subordinates’ acceptance to fulfill this leadership role. If the interest of the organization collides with the interest of their team, some managers act in the interest of their followers accepting potential disadvantages for their organizations and/or external stakeholders. In two experimental studies comprised mainly of German (N = 111) and US (N = 323) managers, we examined combined effects of authentic leadership, organizational identification, and self-perceived team prototypicality on managerial integrity operationalized as ex…
Effectance and control as determinants of video game enjoyment
2007
This article explores video game enjoyment originated by games' key characteristic, interactivity. An online experiment (N = 500) tested experiences of effectance (perceived influence on the game world) and of being in control as mechanisms that link interactivity to enjoyment. A video game was manipulated to either allow normal play, reduce perceived effectance, or reduce perceived control. Enjoyment ratings suggest that effectance is an important factor in video game enjoyment but that the relationship between control of the game situation and enjoyment is more complex. © 2007 Mary Ann Liebert, Inc.
Clonal heterogeneity of thymic B cells from early-onset myasthenia gravis patients with antibodies against the acetylcholine receptor
2014
Myasthenia gravis (MG) with antibodies against the acetylcholine receptor (AChR-MG) is considered as a prototypic autoimmune disease. The thymus is important in the pathophysiology of the disease since thymus hyperplasia is a characteristic of early-onset AChR-MG and patients often improve after thymectomy. We hypothesized that thymic B cell and antibody repertoires of AChR-MG patients differ intrinsically from those of control individuals. Using immortalization with Epstein Barr Virus and Toll-like receptor 9 activation, we isolated and characterized monoclonal B cell lines from 5 MG patients and 8 controls. Only 2 of 570 immortalized B cell clones from MG patients produced antibodies agai…
