The presence now of the Web in every area of life demands studies which constitute it simultaneously both as itself a contextualising object and as anchored in a context. Contextualising because today it directly influences an infinite number of objects, which can no longer be studied without taking account of their echoes online. In transmedia dynamics in particular, we can see how the Web is increasingly becoming an ever-present backdrop to controversies, to the configuration of information and even to interpersonal relationships. Equally, the Web must find its own contextualisation, first of all – since we are historians – from a diachronic perspective. The first challenge is not to remain within the limits set by the technology itself. This twofold approach (the Web in context and the Web as context) suggests how focused we need to be on the construction of an ever-changing socio-technical reality – a return to a totalising, process-focused history which takes account of ongoing developments. We should resist the effects of any discourse tending to fix realities or establish, in hieratic or metonymic fashion, an image of ‘THE’ Web. The present analysis falls into three main sections, which interrogate, in turn, the diachronic or temporal contextualisation, the boundaries or spatial contextualisation, and finally collective and individual experiences of the Web.

The initial setting of fresh concrete is mainly caused by the dissolution of cement grains and the precipitation of calcium-silicate-hydrates during cement hydration. Progressing hydration drives the transition from a dense suspension to a porous solid phase. Fresh mixture of self-compacting concrete (SCC) can be considered as a phase-changing multi-component material and can be described as a continuum at the macro scale, interacting with a set of transport-reaction-diffusion processes which in turn are driven by phenomena at the level of the microstructure. This contribution focuses on a predictive model for the setting of fresh SCC where the liquid-solid phase transition is captured by a phase-field variable using the Ginzburg-Landau type free energy function. Hydration-related chemical reactions together with heat and mass transfer are volume coupled with the mechanical behaviour and determined by the environmental conditions. The weak form of the predictive model is discretised using the finite element method and implemented with the FEniCS computational framework. [less ▲]

The following report contains the results of the Luxembourgish Health Behaviour in School-aged Children (HBSC) study, which was conducted in the year 2014. The HBSC study is a cross-national survey study that collects data every four years in school classes across Europe, Asia and Canada. In Luxembourg, students from primary and secondary schools that teach according to the Luxembourgish curriculum were included in the study. This report contains the data of 7233 students aged 11 to 18 years old. The HBSC study inquires about a wide range of topics, including questions on subjective well-being, nutrition, physical activity, social relationships in- and outside of school, use of addictive substances and sexual behaviour. This report examines these topics mainly with regard to socio-demographic characteristics. With regards to gender, neither boys nor girls are at a clear disadvantage for the researched themes. The position of boys and girls depends on the theme, which means that for certain themes boys are at a disadvantage, whereas for other themes girls are at a disadvantage. Boys indicate higher rates of substance use (alcohol, tobacco and cannabis), higher rates of overweight and they watch more television than girls. However, girls report less physical activity, lower rates of breakfast consumption, more health complaints and lower life satisfaction compared to boys. For almost all the indicators examined, the 11-12-year-olds have the best scores and often the next group (13-14-year-olds) is already performing significantly worse. The only exception in this pattern was found for the variable of bullying: the older the students are, the less often they are victims of bullying. The age 12-13 is therefore considered a critical phase of life from a health perspective. Additionally, the social status of students is of relevance for their health. The large majority of indicators show that the higher the family affluence, the better the results reported by students. Students from the Fondamental are younger, and thus obtain better scores for the majority of indicators than the students from secondary schools. Within secondary schools, better scores are obtained by Secondaire classique students compared to Secondaire technique students. In the international comparison, Luxembourgish students are inconspicuous and often placed in the midfield with average scores. Compared to students in other countries, Luxembourgish students report to do more sports and they report fewer occasions of drunkenness in their life. However, Luxembourg obtained low scores for two indicators: Luxembourgish students have a high number of health complaints (e.g. pain, problems falling asleep, nervousness) and their life satisfaction is relatively low.

This chapter seeks to show the value of a relational, practice-oriented approach – what in STS vocabulary is called ‘unpacking black boxes’, or doing a sociology ‘of assemblages’. The chapter examines how this approach can shed light on the hybrid mobilizations of innovators, consumers, users and entrepreneurs – alongside their creations and cultures – that have made the Web the complex socio-technical system it is today.

The reign of William IV represents a period concerned with questions of national identity, not only in a national context, but also in a global one. Periodicals of the time, such as the Athenaeum, present the co-existence of two related, but inherently opposite conceptions of literature and its functions: Goethe’s idea of Weltliteratur is contemporaneous to developments in the formation and consolidation of national literatures, which can be observed to co-exist even in the early nineteenth-century. World literature, as imagined by Goethe in the 1930s, represents a way of circumventing the inward-looking attitude of nationalism, and of prioritising fluidity and flexibility over stability. National literature, as practiced widely during the nineteenth century, represents a way of grounding national genius in literary texts, either by scrutinising only the works of authors of a specific nationality, or by comparing them in a transnational, intercultural perspective. This article investigates two series of articles published almost concurrently in the Athenaeum: ‘A Biographical and Critical History of the Literature of the last Fifty Years’, by Allan Cunningham in 1833, and ‘Literature of the Nineteenth Century’, by diverse authors between 1834 and 1838. This article highlights the co-existence between different authorial focalisations in historicising and historiographing literature, demonstrating the malleability, undecidability, and arbitrariness of dominant models of national literary identities. I argue that during the 1830s, the Athenaeum’s outlook is decidedly cosmopolitan and international as the contributors engage with European literature equally often as they do with British texts. They are also eager to stretch the readers’ awareness beyond the European context, embracing the wealth of ideas, styles, and perspectives as culturally enriching, but not exotic, erudition.

Cet ouvrage s’inscrit dans le cadre d’une histoire jeune et très contemporaine, celle d’Internet, du Web et des cultures numériques et explore leur fabrique dans les années 1990 en France. Cette recherche, à la croisée de l’histoire des médias, de l’histoire de l’innovation, et de l’histoire sociale et culturelle, reflète les apports d’une approche française de l’histoire d’Internet et du Web. Matérialité et infrastructures, temporalités et trajectoires, espaces et territoires traversent les cinq chapitres du livre. Ils apportent des arguments au choix d’une analyse nationale d’un phénomène pourtant transnational, en s’intéressant à l’attribution des noms de domaine et à la francophonie au sein de la Toile, à la transition entre la culture Minitel et celle du Web, ou encore à la place d’un État qui passe du volontarisme et du monopole des télécommunications à la dérégulation et aux imaginaires des autoroutes puis de la société de l’information. Explorant les pratiques, difficultés, tâtonnements de la période et le tournant grand public du Web, on croise au cours de cette navigation des informaticiens, des entrepreneurs, des politiques, des passionnés de science-fiction, des militants, autant d’acteurs qui se confrontent, débattent, co-construisent. Ils vous invitent à les suivre dans un chantier entre « cathédrale et bazar », pour reprendre Eric Raymond, dont l’exotisme mais aussi l’actualité des débats ne cessent de nous frapper. Bienvenue dans le Cyberespace des années 1990 ! [less ▲]

They challenge our definition of social networks, invite us to consider the continuities and disruptions between these past experiences and those of today, but also the traces left by these communities, to better consider the future of our born-digital heritage.

In this paper, we investigate resource allocation and relay selection in a dual-hop orthogonal frequency division multiplexing (OFDM)-based multi-user network where amplify-and-forward (AF) enabled relays facilitate simultaneous wireless information and power transfer (SWIPT) to the end-users. In this context, we address an optimization problem to maximize the end-users’ sum-rate subjected to transmit power and harvested energy constraints. Furthermore, the problem is formulated for both time-switching (TS) and power-splitting (PS) SWIPT schemes.We aim at optimizing the users’ SWIPT splitting factors as well as sub-carrier–destination assignment, sub-carrier pairing, and relay–destination coupling metrics. This kind of joint evaluation is combinatorial in nature with non-linear structure involving mixed-integer programming. In this vein, we propose a sub-optimal low complex sequential resource distribution (SRD) method to solve the aforementioned problem. The performance of the proposed SRD technique is compared with a semi-random resource allocation and relay selection approach. Simulation results reveal the benefits of the proposed design under several parameter values with various operating conditions to illustrate the efficiency of SWIPT schemes for the proposed techniques.

The recent expansion of Islamic banks raises questions on its economic implications. The aim of this paper is to investigate the impact of Islamic banking development on access to credit. We combine data from a unique hand-collected database that covers Islamic banks with firm-level data covering developing and emerging countries over the period of 2006 to 2009. We find that Islamic banking development has overall no impact on credit constraints, while banking development and conventional banking development alleviate obstacles to financing. However Islamic banking development exerts a positive impact on access to credit when conventional banking development is low. Hence we support the view that Islamic banking does not overall alleviate obstacles to financing, but it can act as substitute to conventional banking. [less ▲]

Most geotechnical design codes and books use the equations of Meyerhof or Terzaghi to calculate shallow foundations. These equations are based on the failure mechanism published by Prandtl for shallow strip foundations. The common idea is that failure of a footing occurs in all cases according to a Prandtl-wedge failure mechanism. To check the failure mechanism and the equations of the currently used bearing capacity factors and correction factors, a large number of finite-element calculations of strip and circular footings have been made. The finite-element calculations show that in cases of soils with high friction angles, soils without cohesion or a surcharge, footings with inclined loading or circular footings, not the Prandtl-wedge failure mechanism, but other failure mechanisms occur. In addition, the currently used equations for the bearing capacity factors and correction factors are too high. Therefore, new equations have been presented in this article. For some correction factors, for example, the inclination factors and the cohesion slope factor, an analytical solution is found. [less ▲]

Ce chapitre présente les résultats de trois collectes de données (2014, 2015, 2016) des ÉpStan au cycle 2.1 et présente avec quelles compétences scolaires les élèves débutent leur scolarité au début du cycle 2.1 et comment celles-ci évoluent sur deux ans. De manière générale, nos résultats montrent que les compétences disciplinaires du cycle 1 portant sur les trois domaines d’apprentissage observés (« compréhension de l’oral en luxembourgeois », « compréhension de l’écrit» et « mathématiques ») sont acquises. Au début du cycle 2.1, la majorité des élèves atteint le Niveau Avancé dans l’ensemble des trois domaines d’apprentissage considérés. Deux ans plus tard, au cycle 3.1, la répartition des élèves sur les différents niveaux de compétence est plus négative qu’au cycle 2.1 et ceci dans la mesure où moins d’enfants ont atteint le Niveau Socle dans l’ensemble des trois domaines d’apprentissage observés. Nos résultats montrent également que, dès le début de la scolarité, différents facteurs extrascolaires (tels que le statut socio-économique et le contexte linguistique) ont une influence extrêmement forte sur les résultats des épreuves et que cette influence augmente au fil des années.
