Influence of the drawing process on the defect generation in multistep-index germanium-doped optical fibers

2009

International audience; Variation of germanium lone pair center (GLPC) concentration in germanosilicate multistep-index optical fibers and preforms was studied using confocal microscopy luminescence technique. The experimental results provide evidence that in the central core region ([Ge] ~11 wt. % ) of our specific canonical samples the ratio [GLPC]/[Ge] is five times larger in fiber than in preforms. The relative influence of the glass composition and of the drawing process on the generation efficiency of the GLPC defects that drive the glass photosensitivity is discussed. The radial distribution of these defects suggests a possible enhancement of the defect creation related to the intern…

Le rituel irlandais de consécration des églises au Moyen Âge : le témoignage des sources irlandaises et bretonnes

2011

L’étude du seul traité irlandais sur la consécration des églises (xie siècle) et sa comparaison avec les sacramentaires et ordines du viiie siècle permettent de relever des analogies avec la liturgie gallicane, mêlée de quelques éléments orientaux. La découverte d’un schéma de dédicace dans le ms 477 d’Angers (ixe siècle), d’origine bretonne (Landévennec) et d’influence irlandaise, confirme quant à elle les singularités du rituel irlandais : inscription d’un double alphabet latin sur le sol ; utilisation de psaumes de malédiction ; circumambulation de l’église en récitant des psaumes graduels. Les textes hagiographiques du viie siècle complètent la compréhension du rituel irlandais : alors …

Voltaire et la justice d'Ancien Régime : la médiatisation d'une imposture intellectuelle

2010

Voltaire passe aujourd’hui pour un heros du progres judiciaire. Il doit cette reputation a des affaires exceptionnelles, rencontrees au soir de sa vie, ou il a su deployer avec succes son genie de la communication. A cette occasion, il a presente un tableau inexact de la justice penale de son temps. La posterite a, le plus souvent, recopie et repete aveuglement les critiques du philosophe sans en verifier la veracite, faisant ainsi passer l’arbre pour la foret et nourrissant une legende noire encore trop vivace.

Who and how? : Preservice teachers as active agents developing professional identities

2016

Abstract This study is part of an ongoing action research project with preservice class teachers in Finland. The study aims to better understand the forms agency takes in preservice teachers' professional identity development. Through the dialogical analysis of student assignments, this study outlines how student teachers are active within their own development and the way in which experiences are drawn on as preservice teachers exert their identity-agency. The results of this study provide a relational picture of identity development highlighting the way in which identity-agency is contextualized, potentially nourished by the relationships between self and other and dependent on experience.

Documenting the indignation: Responses to the 2008 financial crisis in contemporary Spanish cinema

2017

ABSTRACTThe aim of this article is to analyze two Spanish documentary films that reflect on the 2008 financial crisis in Spain, Mercado de futuros (Mercedes Alvarez, 2011) and No estamos solos (Pere Joan Ventura, 2015). These movies could be marked as political for their choice of a collective protagonist and for dealing with the issues of inequality with the purpose of appealing to mobilization and resistance to the neoliberal Western agenda that have provoked social cutbacks after the 2008 crisis. Mercedes Alvarez and Pere Joan Ventura follow the tradition of political documentaries traced by filmmakers such as Dziga Vertov, Joris Ivens, Pere Portabella, and Basilio Martin Patino and open…

Use of code-mixing by young hearing children of Deaf parents

2016

In this study we followed the characteristics and use of code-mixing by eight KODAs – hearing children of Deaf parents – from the age of 12 to 36 months. The children's interaction was video-recorded twice a year during three different play sessions: with their Deaf parent, with the Deaf parent and a hearing adult, and with the hearing adult alone. Additionally, data were collected on the children's overall language development in both sign language and spoken language. Our results showed that the children preferred to produce code-blends – simultaneous production of semantically congruent signs and words – in a way that was in accordance with the morphosyntactic structure of both languages…

Asymmetries of Knowledge and Epistemic Change in Social Gaming Interaction

2014

While a growing number of studies investigate the role of knowledge and interactional management of knowledge asymmetries in conversation analysis, the epistemic organization of multilingual and second language interactions is still largely unexplored. This article addresses this issue by investigating how knowledge asymmetries and changing positions with regard to knowledge impact social interaction in multilingual gaming activities. Drawing on a collection of video recordings of social gaming sessions collected over a two year period and involving the same two participants, we examine how the participants orient to knowledge and deal with knowledge asymmetries while solving game-related p…

Case Distribution and Nominalization: Evidence from Finnish

2009

.  In many languages, case is distributed among many grammatical elements inside of argument DPs. This article shows that case distribution in Finnish is sensitive to certain nontrivial structural properties of those DPs. This makes it possible to use case distribution as a tool to investigate the internal structure of a variety of DPs, including nominalized clauses. It is argued, based on such new evidence, that (i) there exists a syntactic nominalizer head n within various kinds of nominal phrases, and that (ii) genitive argument DPs of nominalized clauses undergo raising analogous to the EPP-triggered DP raising in finite clauses. Furthermore, these genitive arguments are base-generated …
