Living With/Out Proximity: Comparing a Contested Concept in Tort

National audienceCertaines femmes victimes de violences conjugales s’inscrivent dans un parcours de résilience et manifestent une attitude positive, voire passionnée, vis-à-vis de l'apprentissage de connaissances et de capacités nouvelles. Cette observation renvoie au concept d'apprenance proposé en sciences de l'éducation (Carré, 2005).Cette attitude d’apprenance, s’exprimant par différentes pratiques particulièrement autodidactes, orientées vers la compréhension de l’événement traumatique (telles que la lecture d’ouvrages spécialisés sur les violences, l’Etat de Stress Post-Traumatique, la résilience, des récits de vie, mais également des recherches sur internet, le suivi de conférences et de stages en développement personnel, …), pourrait-elle favoriser la résilience ? Ces pratiques sont- elles uniquement le fruit de dispositions apprenantes antérieures au traumatisme ou pourraient-elles émerger à la suite de ce dernier ? On peut par ailleurs s’interroger sur les usages et bénéfices personnels et sociaux que ces femmes font de leurs expériences, de leurs nouvelles connaissances et capacités.Cette recherche en cours tend à répondre à ces questions par une étude à la fois qualitative (par des entretiens autobiographiques) et quantitative (par questionnaire), auprès du public cible. L’enquête exploratoire a consisté en des entretiens autobiographiques auprès de 5 femmes ayant été victimes de violences. Ces entretiens ont montré que ces femmes ont multiplié les ressources afin de comprendre leur histoire, pouvoir mettre des mots sur l’événement traumatique et ainsi pouvoir progressivement s’inscrire dans un parcours résilient. L’ensemble de ces ressources les a conduites non seulement à se rétablir, mais également à développer une véritable expertise. Certaines d’entre elles souhaitent, aujourd’hui, mettre à profit leurs connaissances et compétences acquises de manière expérientielle et didactique, afin de soutenir et accompagner d’autres personnes vulnérables.L’objectif de cette recherche sera, d’une part, de comprendre le lien entre l’apprenance comme ressource et la résilience comme parcours. L’apprenance pourrait ainsi être intégrée parmi les facteurs de résilience. D’autre part, cette recherche sera susceptible d’apporter un élément intéressant au domaine de la victimologie et de la psychotraumatologie, en proposant des pistes complémentaires dans l’accompagnement des anciennes victimes de violences, notamment par le rôle facilitateur et incitateur d’apprentissage du psychothérapeute et du travailleur social

Statistical periodicity in driven quantum systems: General formalism and application to noisy Floquet topological chains

Much recent experimental effort has focused on the realization of exotic quantum states and dynamics predicted to occur in periodically driven systems. But how robust are the sought-after features, such as Floquet topological surface states, against unavoidable imperfections in the periodic driving? In this work, we address this question in a broader context and study the dynamics of quantum systems subject to noise with periodically recurring statistics. We show that the stroboscopic time evolution of such systems is described by a noise-averaged Floquet superoperator. The eigenvectors and -values of this superoperator generalize the familiar concepts of Floquet states and quasienergies and allow us to describe decoherence due to noise efficiently. Applying the general formalism to the example of a noisy Floquet topological chain, we re-derive and corroborate our recent findings on the noise-induced decay of topologically protected end states. These results follow directly from an expansion of the end state in eigenvectors of the Floquet superoperator.Comment: 13 pages, 5 figures. This is the final, published versio

Tweets Are Not Created Equal:investigating Twitter's client ecosystem

This article offers an investigation into the developer ecosystem of platforms drawing on the specific case of Twitter and explores how third-party clients enable different “ways of being” on Twitter. It suggests that researchers need to consider digital data as traces of distributed accomplishments between platforms, users, interfaces, and developers. The argument follows three main steps: We discuss how Twitter’s bounded openness enables and structures distributed data production through grammatization of action. We then suggest ways to explore and qualify sources by drawing on a weeklong data set of nearly 32 million tweets, retrieved from Twitter’s 1% random sample. We explore how clients show considerable differences in tweet characteristics and degrees of automation, and outline methodological steps to deploy the source variable to further investigate the heterogeneous practices common metrics risk flattening into singular counts. We conclude by returning to the question about the measures of the medium, suggesting how they might be revisited in the context of increasingly distributed platform ecosystems, and how platform data challenge key ideas of digital methods research

Site determination and thermally assisted tunneling in homogenous nucleation

A combined low-temperature scanning tunneling microscopy and density functional theory study on the binding and diffusion of copper monomers, dimers, and trimers adsorbed on Cu(111) is presented. Whereas atoms in trimers are found in fcc sites only, monomers as well as atoms in dimers can occupy the stable fcc as well as the metastable hcp site. In fact the dimer fcc-hcp configuration was found to be only 1.3 meV less favorable with respect to the fcc-fcc configuration. This enables a confined intra-cell dimer motion, which at temperatures below 5 K is dominated by thermally assisted tunneling.Comment: 4 pages, 4 figure

A platform independent communication library for distributed computing

We present MPWide, a platform independent communication library for performing message passing between supercomputers. Our library couples several local MPI applications through a long distance network using, for example, optical links. The implementation is deliberately kept light-weight, platform independent and the library can be installed and used without administrative privileges. The only requirements are a C++ compiler and at least one open port to a wide area network on each site. In this paper we present the library, describe the user interface, present performance tests and apply MPWide in a large scale cosmological N-body simulation on a network of two computers, one in Amsterdam and the other in Tokyo
