From the theory of compensatory Internet use, escapism through videogames may constitute a coping strategy that is sometimes helpful but, in some cases, maladaptive. Yet, evidence supporting this view has, to date, been gathered only through the use of explicit self-reported questionnaires, which are known to be biased. Accordingly, the aim of the current study was to test whether the escapism motive is related to a preference for the virtual environment. Method. A laboratory task that allowed the measurement of implicit attitudes, namely, the Affect Misattribution Procedure was created with stimuli from real world and videogames. The task was administered online with a series of questionnaire and completed by 273 online gamers from the community. Results. The results showed that participants had more positive attitudes toward pictures depicting virtual environments than toward those depicting real environments. Furthermore, those participants who frequently used videogames to escape real life and were highly engaged in video gaming had a more pronounced positive implicit attitude toward the virtual environment. Discussion. This study contributes to a better understanding of the psychological processes underlying escapism in videogames and calls for a refinement of the escapism construct, which can be related to both problematic (i.e., potential coping strategy) and nonproblematic patterns of videogame use. Among the limitations, it should be noted that the selection of stimuli related to videogames is restricted to one genre of game, and that the participants’ environment could not be controlled due to the online design.

In the present paper, a model-based fault/attack tolerant scheme is proposed to cope with cyber-threats on Cyber-Physicals Systems. A common scheme based on observers is designed and a state feedback control based on an aperiodic event-triggered framework is given with control synthesis and condition on the switching time. Classical fault tolerant control with Bi-linear Matrix Inequality () approaches are used to achieve novel and better security strategy based on an event-triggered control implementation. The purpose of using the event-based implementation would be to reduce (limit) the total number of transmissions to only instances when the networked control system (NCS) needs attention. Simulation results on a real-time laboratory three tank system are given to show the attack-tolerant control ability despite data deception attacks on both actuators and sensors. A detection/isolation scheme based on residual observers bank is also proposed. [less ▲]

This paper historicizes “rigour”, discipline” and “systematic” as inventions of a certain rational spirit of Enlightenment that was radicalized during the 19th century. These terms acquired temporary value in a transition during the 19th century when a culture of research was established within a modern episteme. Beginning in the 20th century, this development was perceived as problematic, triggering criticism from philosophy and the arts, and even within the sciences. “Discipline”, “rigour” and “systematic” have changed meanings over time, and recent contributions from Digital Humanities are promising for a renewed critical debate about rigour in research. Both digital humanities and quantitative research deal with big data sets aimed at providing a large-scale analysis. However, unlike most quantitative research, digital humanities explore uncertainties as their main focus. Attention to the human-machine collaboration has led to more expansive thinking in scientific research. Digital humanities go further by advancing a metaperspective that deals with the material hermeneutics of data accumulation itself. [less ▲]

The automatic identification of core concepts addressed by a learning resource is an important task in favor of organizing content for educational purposes and for the next generation of learner support systems. We present a set of strategies for core concept identification on the basis of a semantic representation built using the open and available knowledge in the so-called Knowledge Graphs (KGs). Different unsupervised weighting strategies, as well as a supervised method that operates on the semantic representation, were implemented for core concept identification. In order to test the effectiveness of the proposed strategies, a human-expert annotated dataset of 96 learning resources extracted from MOOCs was built. In our experiments, we show the capacity of the semantic representation for the core-concept identification task as well as the superiority of the supervised method. [less ▲]

Cette intervention se propose d'étudier les politiques institutionnelles d'archivage du Web à plusieurs échelles, depuis les aspects organisationnels propres à une institution jusqu'aux enjeux de gouvernance globaux et internationaux. Il s'agira aussi d'étudier en quoi "des formes spécifiques de pouvoir et d'autorité" (Winner, 198 121) peuvent être décelées au sein des processus comme des artefacts produits. Une réflexion sur les périmètres de sélection des contenus (et leurs éventuels biais), la curation à la fois humaine et technique, l'équilibre entre nouvelles formes d'action et cadres imposés (par exemple dans le cadre du dépôt légal) permettra de dévoiler les multiples strates politiques à l'oeuvre dans l'archivage du Web.

As the country with the highest percentage of immigration in Europe, Luxembourg has a very diverse school population. This doctoral project is part of the research project ‘CALIDIE’ that investigates how multilingualism can be capitalized on. In Luxembourg, the teaching of Luxembourgish, German and French accounts for 40.5% of all curricular time. Assessment studies have shown that students of Portuguese, French and Slavic heritage underperform compared to Luxembourgish and German-speaking students in primary schools (MENJE, 2017). While studies in preschool, Year 1 and Year 2 classes show that some teachers begin to draw on children’s semiotic repertoires (Kirsch 2017), the present project targets Years 4 and 5. The focus lies on translanguaging practices. Translanguaging is the enactment of a person’s linguistic and non-linguistic resources. Research in bilingual and trilingual school contexts has shown that translanguaging can promote knowledge, understanding and academic success (García & Sylvan 2011). To help students learn, teachers need to encourage students to make use of their resources in a strategic and responsible way, whatever the status of the languages (García, Johnson & Seltzer 2017). In this paper, I examine the extent to which a fourth-grader of Slovenian language background deploys (or does not deploy) his linguistic repertoire while interacting with peers. Data are drawn from eighteen days of observation and video-recordings of the students’ language use in German, French and Science lessons from September 2017 to July 2018 in a state school in Eastern Luxembourg. The thematic analysis focuses on classroom interactions among students; the learning activities; the languages; and the purposes of their (in)flexible language use. Preliminary results show that peer interactions and child-led learning activities are scarce; the students communicate in the language of instruction; and translanguaging is used to (help) participate. The findings are tentative because data collection is on-going. [less ▲]

Im Rahmen des luxemburgischen Schulmonitorings werden Schlüsselkompetenzen der Schülerinnen und Schüler der luxemburgischen Regelschulen in regelmäßigen Abständen durch die so genannten Épreuves Standardisées (ÉpStan) gemessen. Diese längsschnittliche Begleitung der Schülerinnen und Schüler birgt die einmalige Chance, neue Erklärungsansätze für ein (alt)bekanntes Problem des luxemburgischen Schulsystems zu finden: die großen Unterschiede der Bildungschancen von Schülerinnen und Schüler je nach Geschlecht, sprachlichem und sozioökonomischem Hintergrund. Der vorliegende Beitrag gibt nun einen ersten Einblick in die längsschnittliche Kompetenzentwicklung in den Bereichen Deutsch-Leseverstehen und Mathematik. Hierfür werden die Testergebnisse der untersuchten Schülerkohorte aus den ÉpStan-Kompetenztests 2010 in der 3.Schulstufe den Leistungen in der 9. Schulstufe im Jahre 2016 gegenübergestellt. Die Darstellung der Entwicklungsverläufe mittels Sankey-Flussdiagrammen, erlaubt ein schnelles und intuitives Verständnis, von welchem Kompetenzniveau die Schülerinnen und Schüler in der 3. Klasse starten und welches sie schließlich in der 9. Klasse erreichen. Der Effekt von nachgewiesenermaßen einflussreichen, demografischen (Hintergrund-) Merkmalen wie Geschlecht, sprachlichem Hintergrund und sozioökonomischem Status wird dabei gesondert analysiert. Beim Blick auf die generellen Entwicklungsverläufe in den Bereichen Deutsch-Leseverstehen und Mathematik fällt vor allem eine sehr hohe Stabilität der Kompetenzeinstufungen auf: Schülerinnen und Schüler der 3. Klasse, deren Leistungen auf dem (erwartungskonformen) Niveau Socle oder Niveau Avancé liegen, verfügen in der Regel auch 6 Jahre später über hohe Deutsch- bzw. Mathematikkompetenzen. Umgekehrt verbleibt die Mehrheit der Schülerinnen und Schüler mit anfänglich schwachen Leistungen auch später auf einem niedrigen Kompetenzniveau. Bezieht man nun die Teilergebnisse zum Sprachhintergrund mit ein, lässt sich ganz klar folgern, dass die Unterrichtssprache hierfür einen entscheidenden Faktor darstellt: Schülerinnen und Schüler, die Luxemburgisch oder Deutsch als Muttersprache angeben, können sowohl in Deutsch-Leseverstehen als auch in Mathematik eher ein hohes Niveau halten bzw. sich im Laufe ihrer Schulkarriere auf ein solches verbessern. Portugiesischsprachige bzw. frankophone Schülerinnen und Schüler, die im Allgemeinen ohnehin auf einem niedrigeren Kompetenzniveau starten, können sich nur teilweise deutlich verbessern, profitieren aber vom Wechsel der Unterrichtssprache im Secondaire. Die Analysen zeigen darüber hinaus, dass typische Geschlechtsunterschiede, die auf einen Vorteil für Mädchen beim Lesen und einen leichten Vorteil für Jungen in Mathematik hindeuten, schon anfangs der 3. Klasse bestehen, und über die folgenden 6 Jahre weitgehend stabil bleiben. Zusammenfassend bestätigen die Ergebnisse die bereits mehrfach aufgezeigten landestypischen Probleme, erlauben aber eine feinere Aufschlüsselung und zeitliche Verortung der Wechselwirkungen zwischen Unterrichtssprache, sprachlichem und sozioökonomischem Schülerhintergrund, und bilden so die Grundlage für effektivere Interventionen.

In Luxembourg children engage daily in multilingual practices outside early childhood institutions but often face monolingual practices within (Neumann, 2015). Despite research having debunked the need for strict language separation for effective language learning, children are deprived from drawing on their complete linguistic repertoire (Neumann, 2015). In 2017 Luxembourg has opted for multilingual education in the early years. Formal and non-formal education settings are now required to offer the teaching of Luxembourgish, a familiarization with French and a valorisation of the children’s home languages. Whereas researchers have analysed inclusive language pedagogies (García, Johnson & Seltzer, 2017), studies seldomly examine the children’s active participation and peer interactions in early years settings implementing such multilingual pedagogies (Schwartz & Gorbatt, 2018). The present doctoral study is part of the research project MuLiPEC (Kirsch, 2016-2019) which aims at developing multilingual pedagogies through professional development in early childhood. Drawing on a sociocultural perspective, this paper focusses on two three-year-old children in two non-formal settings and investigates their languaging and interactions with peers and practitioners over a year. The data stem from 31 days of participant observation and videography of the children’s interactions with peers and practitioners and from eight interviews with the practitioners. The ongoing data analysis is based on thematic and interaction analysis. The preliminary findings, firstly, indicate that the children translanguaged, making use of their home language French, features of at least two other languages (e.g. German, English) and non-verbal communication (e.g. actions, gestures, pointing). Secondly, the children developed competences in Luxembourgish and learned new words in other languages from their peers and the practitioners. Finally, akin to Corsaro (2018), the children reproduced the practitioners’ language strategies (e.g. labelling, corrective feedback, translanguaging) during peer interactions and adapted their languaging to their interlocutors. The findings should contribute to research on dynamic multilingual practices and their impact on peer interactions in early childhood education. Corsaro, W.A. (2018).
