Les Balkans sont devenus l’objet d’une importante littérature qui s’attache à déconstruire l’image créée par l’Occident. En mettant l’accent sur les représentations populaires, ces études se basent sur des fictions littéraires et cinématographiques, textes journalistiques, récits de voyageurs, documents politiques et diplomatiques, etc. Ainsi, le balkanisme scientifique semble moins exploré. L’historienne Diana Mishkova se donne donc comme objectif de proposer « une reconstruction historique ...

Определени са стойности в нормативния документ „Временна инструкция за оценка на железния път с пътеизмерителна мотриса ЕМ-120 „PLASSER & THEURER“ за I Категория скорост 130 ˂ V ≤ 160 km/h за клас „В“ – железен път в редовна експлоатация и клас „С“- за допустима безопасна експлоатация. Предложена е промяна на методиката за определяне на балната оценка, като се добавя стойността на оценката за междурелсието, като основен параметър от геометрията на железния път, и формулата да е както следва: където: - QI - обобщен качествен индекс (бална оценка за състоянието на железния път по ос и ниво); - SDV - стандартно отклонение за вертикални пропадания (оценка за състояние по ниво); - SDA - стандартно отклонение за състоянието за флеш (оценка за състояние по ос); - SDT - стандартно отклонение за шахматно пропадане (оценка за състояние по ниво); - SDG - стандартно отклонение за междурелсие (оценка за състояние по ос). This dissertation determines the standardization criteria in a document entitled “Temporary instructions for assessing railway track conditions with an ЕМ-120 „PLASSER & THEURER“ Inspection Body for I Category speed 130 ˂ V ≤ 160 km/h in Class B - railway track in regular exploitation and class C - acceptable level of safe exploitation. The dissertation proposes a methodology for measuring the quality index by including measurements of the gauge as an integral parameter in the railway track geometry. The proposed formula is as follows: where: - QI is a summary quality index (a score assessing the railway track conditions based on axis and level); - SDV is standard deviation of the vertical alignment (assessment based on the condition of the level); - SDA is standard deviation of the horizontal alignment (assessment based on the condition of the axis); - SDT is standard deviation of the twist (assessment based the condition of the level); - SDG is standard deviation of the gauge (assessment based on the condition of the axis).

Les usages généralisés de TIC sont souvent interprétés en termes d’extension de la démocratie ou de révolution numérique. Le constat de la centralité des pratiques numériques dans le quotidien de tous les adolescents semble largement partagé. Ces pratiques « déterritorialisées » conduisent-elles les adolescents à des références culturelles et à des contacts sociaux différents de ceux qu’ils ont dans le monde non virtuel immédiat ? Quel type de ressources les lycéens de milieux défavorisés acq...

Comment expliquer la coexistence de deux logiques qui semblent contradictoires ? Pourquoi la mondialisation progresse-t-elle sans estomper les mouvances nationales-identitaires ? Jean-François Bayart s’attaque à la logique même qui fonde cette question. L’enthnonationalisme dissocie les deux phénomènes comme des entités qui s’excluent mutuellement : l’absence de l’un garantirait la prospérité de l’autre. L’auteur s’engage dès lors à démontrer le lien entre la globalisation comme processus d’e...

A virtual testing of double cantilever beam interlaminar fracture toughness sandwich specimens under different types of dynamic loads and loading rates is considered. The nonlinear dynamic response of those sandwich specimens being fractured during the test is numerically examined using the two-dimensional finite element model within the ABAQUSTM code. The interaction integral method is exploited to extract the dynamic stress intensity factor. Cohesive elements allocated along the face/core interface are used to simulate the dynamic fracturing of the specimens.

Thème majeur en philosophie, en sociologie et en psychologie, revendication centrale de mouvements sociaux, la reconnaissance a commencé, depuis plusieurs années déjà, à intéresser les sciences de l’information et de la communication. La dimension temporelle, partie intégrante d’analyses en sciences sociales, est l’objet de diverses théorisations. Pourtant, les deux concepts semblent se rencontrer rarement dans des études de terrain. Ce constat guide le travail collectif dirigé par Jean-Claud...

Cet ouvrage fait découvrir une séance des ateliers de recherche méthodologiques organisés par l’Ina. Lors de ce débat repris en intégral, deux sociologues, Antonio Casilli et Dominique Cardon, essaient de délimiter les réalités que la notion de digital labor recouvre. Il s’agit d’un ensemble de pratiques numériques, mais aussi d’un domaine de recherche relativement récent. Dans la première partie de cet opuscule, l’exposé d’Antonio Casilli propose une définition souple et dynamique de digital...

In this study, the dynamics and fracture of sandwich plates containing a pre-existing skin-to-core interfacial damage and subinterfacial core damage induced by an incident impact is examined. The dynamic response of sandwich plates with debonding that is allowed to be growing with a time, is simulated by using the finite element method within the ABAQUS code. The forced vibration analysis of impact-damaged sandwich plates is carried out accounting for contact and friction conditions within the debonded region in the simulations with ABAQUS. The damage mechanics approach implemented into ABAQUS via cohesive elements is used for modelling the debonding propagation under impulsive and harmonic loading. The influence of the skin-to-core debonding growth on the global nonlinear dynamics and strength of the sandwich plates is studied in detail.

En sociologue des médias, Vincent Goulet (2010) a déjà consacré d’importants travaux aux rapports des classes populaires à l’information. Son enquête de terrain dans un quartier populaire de l’agglomération bordelaise a mis en évidence des classes populaires beaucoup moins « perdues » ou « dépossédées » que les critiques des médias les décrivaient. C’est par l’évocation d’un constat bruyamment repris par les spécialistes et les critiques des médias que Goulet, essayiste engagé cette fois-ci,...

Since 1951, when the anthropologist Cora DuBois used the term culture shock, many studies relating to cross-cultural adaptation have been produced. Based on research relating to cross-cultural adaptation, the mobile researcher could be helped to move into the period of adjustment as soon as possible in order to avoid culture shock. Organised activities (e.g. social events, trainings) for mobile researchers can act as a catalyst to help them overcome the cultural shock. In order to sustain the Mobile Researcher Integration, the EURAXESS staff involved in the ImpactE project designed a Programme of Effective Soft-Skills Development for Internationally Mobile Researchers, taking into account the social, cultural and professional needs of mobile researchers. Through working together for two years, the ImpactE team has benefitted from the theoretical approaches of cross-cultural adaptation, undertaking practical workshops with peers – the EURAXESS staff - and experimental trainings with internationally mobile researchers, resulting in this Train the Trainer Guide for EURAXESS staff. We have chosen practical topics, substantiated by a few appendices, including templates to be used for organising events for mobile researchers, Moreover, the selective list of references provides resources used and published by the project team, other EURAXESS network manuals, theoretical resources, and practical tools for organising training. The list is organised by grouping the references by the mentioned topics. Most of the references are online resources.

We detect topological semigroups that are topological paragroups, i.e., are isomorphic to a Rees product of a topological group over topological spaces with a continuous sandwich function. We prove that a simple topological semigroup $S$ is a topological paragroup if one of the following conditions is satisfied: (1) $S$ is completely simple and the maximal subgroups of $S$ are topological groups, (2) $S$ contains an idempotent and the square $S\times S$ is countably compact or pseudocompact, (3) $S$ is sequentially compact or each power of $S$ is countably compact. The last item generalizes an old Wallace's result saying that each simple compact topological semigroup is a topological paragroup., 8 pages

We prove that the semigroup operation of a topological semigroup $S$ extends to a continuous semigroup operation on its the Stone-\v{C}ech compactification $\beta S$ provided $S$ is a pseudocompact openly factorizable space, which means that each map $f:S\to Y$ to a second countable space $Y$ can be written as the composition $f=g\circ p$ of an open map $p:X\to Z$ onto a second countable space $Z$ and a map $g:Z\to Y$. We present a spectral characterization of openly factorizable spaces and establish some properties of such spaces., Comment: 13 pages
