Forced Compliance, Double Forced Compliance and Experimental Dynamics in Social Representations
2007
The present article deals with changes in the subjects’ social representation of a topic (i.e. how they think about “studying at a school”) due to their single or double forced compliance in a counter-attitudinal direction. The single forced compliance was manipulated in two ways, first by having the subjects write an essay (Study 1), and second by having them hold a speech (Study 2). The double forced compliance consisted of having the subject write an essay plus hold a speech (Study 3). The changes in social representation were assessed at two levels, first at the level of the subjects’ responses to a questionnaire (some items of which had central and other items had peripherical meanings…
« Lieux communs : gendarmes et policiers dans les villes de la Troisième République (1870-1914) »

L'application de la loi hors les tribunaux : les gendarmes et les policiers, "leges animatae" de la République (1870-1914) ?
2006
International audience; Les policiers et les gendarmes de la Troisième République sont-ils comme les gardiens qui arrêtent le Joseph K. du Procès et exécutent mécaniquement la sentence de juges incarnant une norme incontestable ? Si les représentations corporatives des forces de l'ordre confortent cette vision kafkaïenne d'une totale application de la loi par les auxiliaires judiciaires, la réalité est d'une diversité plus surprenante ; cette variété pose la question de la mise en œuvre de la loi hors les tribunaux et de son adaptation aux contraintes sociales par les agents chargés de son exécution. La typologie des facteurs favorisant les distorsions entre la lettre de la loi et son appli…

Optical force rectifiers based on PT-symmetric metasurfaces
2018
We introduce here the concept of optical force rectifier based on parity-time symmetric metasurfaces. Directly linked to the properties of non-Hermitian systems engineered by balanced loss and gain constituents, we show that light can exert asymmetric pulling or pushing forces on metasurfaces depending on the direction of the impinging light. This generates a complete force rectification in the vicinity of the exceptional point. Our findings have the potential to spark the design of applications in optical manipulation where the forces, strictly speaking, act unidirectionally. R.A. and B.G. would like to acknowledge financial support from the Max Planck Society. J.C. acknowledges the suppor…
Manufacturing and characterization of Al matrix composites with nano reinforcements via cold spraying
2019
This study aims at developing new routes for manufacturing Al matrix composites (AMCs) strengthened with nano reinforcements by solid-state cold spraying (CS) process. Three different AMCs including CNTs/Al, TiB2/AlSi10Mg and TiB2/7075Al were successfully fabricated by CS of the composite powders prepared using different approaches. The microstructure evolution of as-sprayed composite samples was investigated by means of different characterization methods like X-ray diffraction (XRD), scanning (SEM) and transmission electron microscopy (TEM) and electron backscatter diffraction (SEM/EBSD). The adhesion strength, tribological behaviour, corrosion properties as well as the mechanical performa…
Thermodynamics and kinetics of ion permeation in wild-type and mutated open active conformation of the human α7 nicotinic receptor
2020
Molecular studies of human pentameric ligand-gated ion channels (LGICs) expressed in neurons and at neuromuscular junctions are of utmost importance in the development of therapeutic strategies for neurological disorders. We focus here on the nicotinic acetylcholine receptor nAChR-α7, a homopentameric channel widely expressed in the human brain, with a proven role in a wide spectrum of disorders including schizophrenia and Alzheimer's disease. By exploiting an all-atom structural model of the full (transmembrane and extracellular) protein in the open, agonist-bound conformation we recently developed, we evaluate the free energy and the mean first passage time of single-ion permeation using …
