L'interpretazione dei trattati che determinano frontiere
2015
L'articolo intende dimostrare che l'interpretazione dei trattati che determinano frontiere presenta interessanti differenze rispetto alle regole codificate nella Convenzione di Vienna. Più precisamente. per quanto concerne gli effetti giuridici, i trattati in materia di fontiere sono stati interpretati secondo le direttive metodologiche indicate nella Convenzione di Vienna, attribuendo peraltro una certa importanza al principio della "stabilità delle frontiere". Un approccio diverso è generalmente adottato invece per quanto riguarda l'interpretazione delle clausole che definiscono le frontiere dal punto di vista del loro contenuto. In primo luogo, il principio della stabilità delle frontier…
Frontières des communautés polarisées : application à l'étude des théories complotistes autour des vaccins
2021
Les données des réseaux sociaux sont de plus en plus utilisées pour en extraire de la valeur, dans des domaines tels que le marketing, la politique ou la sociologie. Celles-ci peuvent être représentées sous forme de graphes, en modélisant précisément les interactions à travers des liens dirigés et pondérés. Dans l'analyse des données des réseaux sociaux, l'étude des communautés est une étape essentielle. Toutefois, pour une interprétation fine des phénomènes, il est également nécessaire d'étudier leurs interactions et de pouvoir détecter des traces de polarisation. Nous proposons une méthode qui permet d'évaluer l'antagonisme des communautés et d'identifier leurs frontières dans des réseaux…

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…
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…
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…
Crossing Phrase Boundaries In Music
2018
This paper presents a new model for segmenting symbolic music data into phrases. It is based on the idea that melodic phrases tend to consist of notes, which increase rather than decrease in length towards the phrase end. Previous research implies that the timing of note events might be a stronger predictor of both theoretical and perceived segmentation than pitch information. Our approach therefore relies only on temporal information about note onsets. Phrase boundaries are predicted at those points in a melody where the difference between subsequent note-to-note intervals reaches minimal values. On its own, the proposed model is parameter-free, does not require adjustments to fit a partic…
Enablers of and constraints on employees' information sharing on enterprise social media
2020
PurposeThe purpose of this study is to investigate the various enablers of and constraints on employees' information sharing on an enterprise social media platform. It draws on two theoretical perspectives, communication privacy management theory and the technology affordance framework, as well as on empirical data in an attempt to paint a comprehensive picture of the factors shaping employees' decisions to share or not share information on enterprise social media.Design/methodology/approachThis qualitative field study is based on semi-structured interviews and enterprise social media review data from a large Nordic media organization.FindingsOn an enterprise social media platform, privacy …
