Les classes en Europe se diversifient. Cette diversification transforme l’exercice du métier enseignant tout en lui offrant de nouvelles opportunités de développement. Cet article explore l’hypothèse qu’en utilisant des outils issus de paradigmes au départ distincts – les approches multimodales du discours issues de la sémiotique sociale et les travaux sur le plurilinguisme dans le champ de la linguistique appliquée – on peut faire émerger une vision plus compréhensive des dilemmes et des questions que la diversité pose, en particulier pour l’enseignant débutant. En partant de l’analyse d’une première leçon de français dans une classe très internationale et un contexte d’enseignement trilingue, l’article s’attache à dresser une première cartographie de ces dilemmes. Cinq défis en particulier sont relevés (relatifs à la différenciation, la reconnaissance du travail sémiotique, l’évaluation, la reconnaissance des répertoires des élèves, et aux compétences linguistiques des enseignants). La cartographie est posée comme un préalable nécessaire à une réflexion plus large sur les moyens d’action à mettre en oeuvre pour soutenir l’action enseignante en contexte linguistiquement hétérogène.

Illegal employment by third country nationals is a reality in Luxembourg. However, as well as in the case of grey and informal economy, it is rather hard to grasp or quantify to which extent. Nevertheless, the problem is not as significant as the one of the posted workers which is more relevant and worrisome and needs to be situated in the context of a labour market of the Greater Region. In the past, several labour related regularisation measures have been implemented in Luxembourg in order to provide both employers and employees the possibility to regularise situations of illegal employment. The last labour related regularisation measure was implemented in early 2013 in the context of the transposition of the Employers' Sanctions Directive 2009/52 by law of 21 December 2012. During this regularisation, the Directorate of Immigration received 664 applications. These regularisations give a partial indication of the extent of the phenomenon, even though these numbers do not provide a real picture of the problem because the conditions of this regularisation were very strict and in a very short time frame (less than two months) and a certain number of irregular migrants’ workers were not willing to expose themselves by applying and preferred to remain undetected. This regularisation also provided information on the main sectors were the phenomenon is found in order of importance: HORECA, cleaning, crafts, industry and construction. The Ministry of Labour, Employment and Social and Solidary Economy at the end of the regularisation has insisted in the need to increase the number of controls to employers. The law of 21 December 2012 established administrative as well as criminal sanctions for employers who illegally employ irregularly staying third country nationals, particularly in relation to offenses to the Labour Code in aggravating circumstances. This law amended also article 89 of the Immigration Law abrogating the possibility of making labour related regularisations. The Inspectorate of Labour (‘Inspection de Travail et des Mines’, hereafter called ITM), which is in charge of labour inspections and the control of illegal employment of TCNs in Luxembourg, is currently going through a restructuring phase following the latest audit of this administration from January 2015. Particularly the current insufficient number of staff of the ITM, which is in need of a significant short term increase of staff, represents a main challenge in the field of illegal employment in Luxembourg. It is also in the context of this restructuring phase of the responsible administration that the drafting of this study presented a number of challenges, especially in relation to the operational and statistical part of the template. The information regarding the conditions to be fulfilled by both the employers and the employees in the context of an employment relationship are available on the website of the concerned authorities. Furthermore, they are disseminated by the NGOs working in the field, even though there are no specific campaigns targeted to prevent illegal employment of TCNs. The matter was raised in the context of the ‘social identification badge’, which was introduced in 2013 in order to fight against social dumping in particular in the construction sector. One national stakeholder suggested that the ‘social identification badge’ could be revised and adapted to other economic sectors in order to better monitor and prevent illegal employment. In regards to access to justice and enforcement of rights of illegally employed TCNs, Luxembourg foresees the right for illegally employed TCNs to make a claim against their employer, including in cases in which they have, or have been, returned. This claim falls under the general provisions concerning the right to bring a case before civil courts. The Labour Code establishes that the employer who has employed an irregular staying third-country national must pay to the third-country national the following amounts: 1) salaries and any other emoluments, which a similar employee would have benefited for the same employment; 2) the total amount of outstanding remuneration as well as the cost of the transfer of these amounts to the third-country national to the country to which s/he is returned; 3) the total amount of unpaid social contributions and taxes, including administrative fines, as well as, court and legal fees. In addition, the Labour Code establishes that the third-country national who has been illegally employed before the execution of any return decision has to be systematically and objectively informed by the control agents of his/her rights to recover the outstanding remunerations and back payments, as well as the right to benefit from free of charge legal aid in order to attempt a recovery action against the employer, even if the third-country national has already been returned. Labour unions can support and assist TCNs in legal proceedings related to social and labour law, provided that they have been given a mandate to do so. Eventual costs of administrative and civil proceedings can be taken in charge by the labour unions if the TCN is a member of the respective labour union. The Law does not establish fines against TCN’s who were illegally employed. The TCN may be issued a return decision and lose his/her residence rights; however, the Directorate of immigration processes these situations on a case-by-case basis and inform the persons concerned to terminate the illegal employment situation.

The paper focuses on damage detection of civil engineering structures and especially on concrete bridges. A method for structural health monitoring based on vibrational measurements is presented and discussed. Experimentally identified modal parameters (eigenfrequencies, mode shapes and modal masses) of bridge structures are used to calculate the inverse stiffness matrix, the so-called flexibility matrix. By monitoring of the stiffness matrix, damage can easily be detected, quantified and localized by tracking changes of its individual elements. However, based on dynamic field measurements, the acquisition of the flexibility matrix instead of the stiffness matrix is often the only choice and hence more relevant for practice. But the flexibility-based quantification and localisation of damage are often possible but more difficult, as it depends on the type of support and the location of the damage. These issues are discussed and synthetized, that is an originality of this paper and is believed useful for engineers in the damage detection of different bridge structures. First the theoretical background is briefly repeated prior to the illustration of the differences between stiffness and flexibility matrix on analytical and numerical examples. Then the flexibility-based detection is demonstrated on two true bridges with real-time measurement data and the results are promising. [less ▲]

A study was conducted in four new energy efficient schools in Luxembourg with excellent primary energy consumption values, where the indoor thermal comfort and the air quality was assessed by technical measurements and by surveys. Two schools were equipped with mechanical ventilation with heat recovery and two were without, i.e. ventilation there was manually controlled by opening the windows. Further to the C02-concentration as indicator for the air quality all other important comfort parameters were measured, why the well-known indicators according to FANGER could be calculated, i.e. the „Predicted Mean Vote (PMV)“ and the „Predicted Percentage of Dissatisfied (PPD)“. The individual perceived indoor comfort was analyzed by standardized questionnaires for a period of four weeks. One aim of the study was to compare natural ventilation by opening and closing the windows with the mechanical ventilation in all named aspects. In total there was a good agreement between the measurements and the survey. The results show that in general mechanical ventilation in schools lead to better physical measured values and to better subjective perception of the users. However those buildings suffer from a very low relative humidity, though it is rarely sensed by the occupants. Furthermore, in one of the mechanically ventilated buildings the air velocity was very high and led to draft-perception. The detected air temperature was heterogeneous and independent of the ventilation concept, leading to an individual judgement of PMV for the different buildings. Users should always have the possibility of interaction and control to adjust the indoor climate according to their individual needs and to correct smaller technical shortcomings. [less ▲]

Growth of hard-rod monolayers via deposition is studied in a lattice model using rods with discrete orientations and in a continuum model with hard spherocylinders. The lattice model is treated with kinetic Monte Carlo simulations and dynamic density functional theory while the continuum model is studied by dynamic Monte Carlo simulations equivalent to diffusive dynamics. The evolution of nematic order (excess of upright particles, “standing-up” transition) is an entropic effect and is mainly governed by the equilibrium solution, rendering a continuous transition [Paper I, M. Oettel et al., J. Chem. Phys. 145, 074902 (2016)]. Strong non-equilibrium effects (e.g., a noticeable dependence on the ratio of rates for translational and rotational moves) are found for attractive substrate potentials favoring lying rods. Results from the lattice and the continuum models agree qualitatively if the relevant characteristic times for diffusion, relaxation of nematic order, and deposition are matched properly. Applicability of these monolayer results to multilayer growth is discussed for a continuum-model realization in three dimensions where spherocylinders are deposited continuously onto a substrate via diffusion.

With this article we want to illustrate how the central publications of the European Union legitimate a role of Career Guidance Services (CGS) that help in establishing a desired form of social order. Using the Sociology of Knowledge Approach to Discourse, we reconstructed four typical metaphorical conceptualisations of CGS that go along with desirable and taken-for-granted subject positions. The results reveal the assigned active role of CGS in establishing a specific vision of and in transforming the European society. We conclude by outlining the ways in which critique is expressed within the discourse and by highlighting the inherent ambivalences of these practices of critique. [less ▲]

This paper investigates a self-organized critical approach for dynamically load-balancing computational workloads. The proposed model is based on the Bak-Tang-Wiesenfeld sandpile: a cellular automaton that works in a critical regime at the edge of chaos. In analogy to grains of sand, tasks arrive, pile up and slip through the different processing elements or sites of the system. When a pile exceeds a certain threshold, it collapses and initiates an avalanche of migrating tasks, i.e. producing load-balancing. We show that the frequency of such avalanches is in power-law relation with their sizes, a scale-invariant fingerprint of self-organized criticality that emerges without any tuning of parameters. Such an emergent pattern has organic properties such as the self-organization of tasks into resources or the self-optimization of the computing performance. The conducted experimentation also reveals that the system is in balanced (i.e. not driving to overloaded or underutilized resources) as long as the arrival rate of tasks equals the processing power of the system. Taking advantage of this fact, we hypothesize that the processing elements can be turned on and off depending on the state of the workload as to maximize the utilization of resources. An interesting side-effect is that the overall energy consumption of the system is minimized without compromising the quality of service. [less ▲]

Strain gradient plasticity theories are being widely used for fracture assessment, as they provide a richer description of crack tip fields by incorporating the influence of geometrically necessary dislocations. Characterizing the behavior at the small scales involved in crack tip deformation requires, however, the use of a very refined mesh within microns to the crack. In this work a novel and efficient gradient-enhanced numerical framework is developed by means of the extended finite element method (X-FEM). A mechanism-based gradient plasticity model is employed and the approximation of the displacement field is enriched with the stress singularity of the gradient-dominated solution. Results reveal that the proposed numerical methodology largely outperforms the standard finite element approach. The present work could have important implications on the use of microstructurally-motivated models in large scale applications. The non-linear X-FEM code developed in MATLAB can be downloaded from www.empaneda.com/codes. [less ▲]
