« Le problème de la délimitation des concepts psychologiques chez Wittgenstein »
2010
International audience; la philosophie peut être décrite comme un travail de cartographie conceptuelle. Mais cela implique-t-il que les frontières entre les concepts en question sont parfaitement définies ? Non, répond Wittgenstein. On examine la portée de cette thèse sur un cas à la fois particulier et essentiel : celui des concepts dit ‘psychologiques’.
Dynamic Sustainability Assessment Tool: Case Study of Green Biorefineries in Danish Agriculture
2020
In this work, a novel, dynamic sustainability assessment tool is presented and validated in a case study. This tool combines two methods&mdash
Effect of in Doping on the ZnO Powders Morphology and Microstructure Evolution of ZnO:In Ceramics as a Material for Scintillators
2018
Transparent ZnO ceramics are of interest for use as material for high-efficiency fast scintillators. Doping ZnO ceramics in order to improve complex of their properties is a promising direction. In the present research, the role of indium in the ZnO nanopowders surface interactions and in the change of microstructures and photoluminescence (PL) characteristics of sintered cera-mics is considered. Undoped and 0.13 wt% In doped ZnO ceramics are obtained by hot pressing sintering. It has been found that indium leads to the transition of initially faceted ZnO particles to rounded, contributing to good sintering with formation of diffusion active grain boundaries (GBs). Unlike ZnO ceramics, ZnO:…
The effect of Ag, Pb and Bi impurities on grain boundary sliding and intergranular decohesion in Copper
2016
We investigate the changes in grain boundary sliding (GBS) and intergranular decohesion in copper (Cu), due to the inclusion of bismuth (Bi), lead (Pb) and silver (Ag) substitutional impurity atoms at a $\Sigma$5 (0 1 2) symmetric tilt grain boundary (GB), using a first-principles concurrent multiscale approach. We first study the segregation behavior of the impurities by determining the impurity segregation energy in the vicinity of the GB. We find that the energetically preferred sites are on the GB plane. We investigate the intergranular decohesion of Cu by Bi and Pb impurities and compare this to the effect of Ag impurities by considering the work of separation, $W_s$ and the tensile st…
Visibilities and invisibilities in academic work and career building
2021
In the current turbulent higher education environment, academic work and career building are in a state of flux. The implementation of the principles of New Public Management have intensified managerial control over academic work. Growing dependence on external funding and metrics-based performance assessments have made career building increasingly competitive, selective, and risky. Disciplinary and organisational boundaries have been dissolving as interdisciplinary and cross-sectoral ways of collaboration have become policy priorities. These trends have challenged visible boundaries between disciplines, organisations, sectors, work tasks and academic roles. However, at the same time, new v…
All-inclusiveness in Legal Language. Cross-Cultural Perspectives in Specialized Discourse
2008
This book explores recent theoretical and practical changes in the investigation of language and context, with a particular attention to legal language as a highly specialized discourse. Given the huge variety of human experiences, any approach to language cannot be solely conducted at the level of grammatical rules and structures, but at the level of social contexts and contextual backgrounds as well. In fact, important form-function correlations are discovered when lexico-grammatical investigations are supported by sociocultural and psycho-cognitive enquires about the way in which textual artefacts (and, particularly, specialized texts) are conventionally and linguistically organized and …
Kjønn og religiøse grenser: Unge muslimer og kristnes forhandlinger av kjønn i migrantmenigheter
2019
Artikkelen belyser unge muslimer og kristnes forhandling av kjønn i migrantmenigheter: 1) Hvordan forhandler unge muslimer og kristne forventningene knyttet til kjønn, forbundet med religiøse klesdrakter og kjønnsdelte arbeidsoppgaver? Og 2), hva kan ungdommenes oppfatninger av religiøse koder og kjønnsdelte arbeidsoppgaver fortelle om symbolsk grensedragning mellom deres tilhørighet til en minoritetsgruppe og tilhørighet til majoritetssamfunnet? Data består av 23 kvalitative intervjuer med tenåringer og unge voksne i alderen 16–35 år. Ungdommene forhandlet stadig kleskoder og kjønnsdelte arbeidsoppgaver ut fra ulike religiøse, moralske og kulturelle forventninger. De skilte mellom religion…
Rzeczywistość językowa a lingwistyka
2017
Language reality and linguistics. The author considers the ąuestion of the boundaries of language and linguistics, referring to the so-called full scientific theory. In the complex hierarchical-network structure of this theory, one can distinguish three levels: the philosophical basis, the theoretical-methodological level, and the empirical part. The article focuses on the ontological and epistemologica/-axiological assumptions of the theory of language. One may distinguish between four ways of the existence of language reality, which remain in mutual relatedness (concrete texts, language system, individual and col!ective language awareness). Discussing the contemporary cognitive situation …
A coupled discontinuous Galerkin-Finite Volume framework for solving gas dynamics over embedded geometries
2021
Author(s): Gulizzi, Vincenzo; Almgren, Ann S; Bell, John B | Abstract: We present a computational framework for solving the equations of inviscid gas dynamics using structured grids with embedded geometries. The novelty of the proposed approach is the use of high-order discontinuous Galerkin (dG) schemes and a shock-capturing Finite Volume (FV) scheme coupled via an $hp$ adaptive mesh refinement ($hp$-AMR) strategy that offers high-order accurate resolution of the embedded geometries. The $hp$-AMR strategy is based on a multi-level block-structured domain partition in which each level is represented by block-structured Cartesian grids and the embedded geometry is represented implicitly by a…
SPH modeling of blood flow in cerebral aneurysms
Gli aneurismi cerebrali sono dilatazioni patologiche di arterie cerebrali. Queste patologie hanno un intrinseco rischio di rottura con conseguenti emorragie intracraniche. Sebbene i meccanismi di formazione, crescita e rottura degli aneurismi cerebrali non sono ancora del tutto compresi, è comunemente riconosciuto che in questi processi i fattori emodinamici giocano un ruolo molto importante. Le simulazioni numeriche possono fornire utili informazioni sull'emodinamica e possono essere usate per applicazioni cliniche. Nei tradizionali metodi numerici basati su una griglia di calcolo il processo di discretizzazione dei vasi cerebrali sui quali insiste un aneurisma è molto complesso. D’altra p…
