This presentation focuses on the relationship between the language policy, language ideologies and language practices in a nursery class in trilingual Luxembourg. Individual multilingualism is an educational goal in Luxembourg, a small country in central Europe, and, thus, children learn Luxembourgish from the compulsory nursery school, become literate in German in Year 1 and learn oral and written French from Year 2 and Year 3, respectively. Currently, 62.4% of the children do not speak Luxembourgish on school entry (MENJE 2016). Many speak Portuguese, French or a language of the Balkans. As a result, educational policies focus on the teaching of Luxembourgish from preschool, sometimes at the expense of other languages. Gretsch and Kirsch (2015) developed the app iTEO in order to promote innovative teaching methods that capitalize on the children’s diverse language resources and that promote a dynamic view of bilingualism. This ipad app, which allows for the recording and editing of oral speech, was designed with social-constructivist theories and Bakhtin’s theory of dialogism in mind. This case-study presents the ways in which a preschool teacher’s ideological beliefs influence a child’s language use over a period of two years leading to the child’s understanding of the legitimacy of translanguaging. The focus lies on the interplay between the educational policy focusing on the teaching of Luxembourgish, the teacher’s language ideologies rooted in her multilingual identity and in societal multilingualism, and the child’s experiences of separating languages at home (Kirsch, 2014). The data stem from a qualitative, longitudinal study using a multi-method approach. The study shows that dialogue between teachers, parents, children, policy-makers and researchers can contribute to shifting ideologies and to opening up dynamic languaging spaces. [less ▲]

We study pivotal decomposition schemes and investigate classes of pivotally decomposable operations. We provide sufficient conditions on pivotal operations that guarantee that the corresponding classes of pivotally decomposable operations are clones, and show that under certain assumptions these conditions are also necessary. In the latter case, the pivotal operation together with the constant operations generate the corresponding clone. [less ▲]

This paper examines the extent to which well-being levels change in the transition to retirement depending on transitioning from being employed, unemployed, or economically inactive. Whereas transitioning from employment to unemployment has been found to cause a decrease of subjective well-being with more time spent in unemployment, it is not clear how transitioning from unemployment to retirement affects well-being levels. We use the Survey of Health, Ageing and Retirement in Europe to monitor life satisfaction of respondents who retire in between two waves. We portray well-being scores before and after retirement and then identify the change in life satisfaction during the retirement transition using a First Difference model. Results indicate that being unemployed before retirement is associated with an increase in life satisfaction, but presents mainly a catching-up effect compared to employed persons transitioning to retirement. Retirement from labour market inactivity does not lead to significant changes in well-being. Findings are robust to selection into unemployment and country differences. As well-being of unemployed persons recovers after transitioning to retirement, especially the currently unemployed population should be supported to prevent detrimental consequences of economically unfavourable conditions and lower well-being.

Code smells are symptoms of poor design or implementation choices that have a negative effect on several aspects of software maintenance and evolution, such as program comprehension or change- and fault-proneness. This is why researchers have spent a lot of effort on devising methods that help developers to automatically detect them in source code. Almost all the techniques presented in literature are based on the analysis of structural properties extracted from source code, although alternative sources of information (e.g., textual analysis) for code smell detection have also been recently investigated. Nevertheless, some studies have indicated that code smells detected by existing tools based on the analysis of structural properties are generally ignored (and thus not refactored) by the developers. In this paper, we aim at understanding whether code smells detected using textual analysis are perceived and refactored by developers in the same or different way than code smells detected through structural analysis. To this aim, we set up two different experiments. We have first carried out a software repository mining study to analyze how developers act on textually or structurally detected code smells. Subsequently, we have conducted a user study with industrial developers and quality experts in order to qualitatively analyze how they perceive code smells identified using the two different sources of information. Results indicate that textually detected code smells are easier to identify and for this reason they are considered easier to refactor with respect to code smells detected using structural properties. On the other hand, the latter are often perceived as more severe, but more difficult to exactly identify and remove. [less ▲]

Abstract zur Tagung „Kommunale Selbstinszenierung“ der Internationalen Kommission für Stadtgeschichte, des Schweizerischen Arbeitskreises für Stadtgeschichte und des NCCR 'Mediality. Historical Perspectives' Universität Zürich, 3./4./5. September 2015 Martin Uhrmacher (Universität Luxemburg) „Leprosorien als kommunale Repräsentationsbauten im vorstädtischen Raum. Ein neuer Blick auf eine bisher wenig beachtete städtische Baugattung“ Die vor den Mauern mittelalterlicher und frühneuzeitlicher Städte gelegenen Leprosorien werden heute zumeist noch immer als abgelegene und verborgene Orte der Exklusion angesehen, durch Zäune und Mauern von der Außenwelt getrennt. Dementsprechend wird auch der Baugattung „Leprosorium“ nur wenig architektonischer Wert zugebilligt, wie bspw. im Ausstellungskatalog „Aussatz – Lepra – Hansen-Krankheit: Demnach hatten sie „keinerlei repräsentative Bedeutung, im Gegenteil: eher unauffällig sollten sie sein, verborgen vor dem Blick der Stadtbewohner und Reisenden“. Im 2005 von Monika Escher und Frank G. Hirschmann publizierten Syntheseband „Die urbanen Zentren des hohen und späten Mittelalters“ zur Geschichte mittelalterlicher Städte zwischen Rhein und Maas werden Leprosorien zudem als „nicht wertungsrelevantes“ Urbanitäts- und Zentralitätskriterium“ bezeichnet; begründet mit der angeblichen „Tatsache, daß in der Regel der topographische Bezug zur Stadt gering war“. In der jüngeren Forschung hat sich diese Einschätzung nun grundlegend gewandelt. Leprosorien gelten aufgrund ihrer besonders prominent und exponiert ausgewählten Standorte an Kreuzungen, Brücken und Hauptausfallstraßen als präsente und das städtische Umland prägende kommunale Einrichtungen, die ein fester Bestandteil der städtischen Lebenswelt waren. Sie dienten nicht dazu, ihre Bewohner zu verstecken, sondern waren vielmehr mit Stiftungen und Spenden versehene städtische Einrichtungen, die vom Rat und den Bürgern auch als Prestigeobjekte betrachtet wurden. Anhand ausgewählter Beispiele wird aufgezeigt, wie Leprosorien als Repräsentationsobjekte der Stadtgemeinden auch dem bürgerlichen Selbstverständnis Ausdruck verliehen. [less ▲]

Abstract Konferenz 200 Jahre Wiener Kongress Martin Uhrmacher Neue Staaten – neue Grenzen. Die Großregion zwischen den Grenzbereinigungen des Ancien Régime und der Neuordnung durch den Wiener Kongress (1779 – 1816). Der Vortrag untersucht die Veränderung von Grenzen und Ihre Entwicklung von sich teils überlagernden und durch Enklaven und Gemeinsherrschaften durchsetzten historisch gewachsenen Grenzsäumen hin zu begradigten, fest definierten und teils naturräumlichen Scheidelinien folgenden Staatsgrenzen. In der heutigen Großregion vollzog sich dieser fundamentale Wandel in nur drei Jahrzehnten: Er gliederte die Region vollkommen neu. Zunächst waren es 1779 mit dem Brüsseler Vertrag nach jahrzehntelangen Verhandlungen endlich zu einem Ausgleich zwischen Österreich und Frankreich gekommen, der die Grenzstreitigkeiten beseitigte und neue, begradigte Grenzen exakt festlegte. Ein ähnlicher Vertrag wurde auch zwischen Österreich und Kurtrier abgeschlossen. Doch die als endgültig geplanten Regelungen bestanden nur wenige Jahre: Infolge der französischen Revolution annektierte die französische Republik am 1. Oktober 1795 die österreichischen Niederlande mit dem Herzogtum Luxemburg und kurz darauf auch Kurtrier und die anderen linksrheinischen Territorien. Alle Staaten wurden aufgelöst und gehörten nun zum französischen Staatsgebiet; Teile der alten Grenzen bestanden als Départementsgrenzen weiter. Nach der Absetzung Napoleons beschloss der Wiener Kongress 1815 eine Neuordnung Europas. Doch im Maas-Moselraum blieben mit Ausnahme Frankreichs alle Territorien und Landesherrschaften, die hier seit dem Früh- und Hochmittelalter bestanden hatten verschwunden. Sie wurden ersetzt durch das neu gegründete Großherzogtum Luxemburg und das ebenfalls neu gegründete Königreich der Vereinigten Niederlande sowie durch die preußische Rheinprovinz, die den gesamten östlichen Teil umfasste. Bei der territorialen Neugliederung griff man in Teilen auf die bis 1795 bestehenden Grenzen des alten Herzogtums zurück. In der Schlussakte des Wiener Kongresses behandeln die Artikel 66 bis 69 das Großherzogtum Luxemburg. Hier werden die Grenzen des neuen Staates allerdings nur grob umrissen; detaillierte Regelungen blieben späteren Verträgen vorbehalten. Unstrittig war die Süd- und Westgrenze mit Frankreich; sie entsprach der 1769/79 festgesetzten und bis 1795 gültigen Linie mit Ausnahme des ehemaligen Herzogtums Bouillon als Zugewinn. Vollkommen neu festgelegt wurde jedoch die Ostgrenze: Mit der Schlussakte des Wiener Kongresses waren alle hier an Luxemburg angrenzenden Gebiete an das Königreich Preußen gefallen. In den Verträgen von Aachen (26. Juni 1816) und Kleve (7. Oktober 1816) einigten sich die niederländische und die preußische Seite darauf, dass die Flussläufe von Mosel, Sauer und Our zukünftig die gemeinsame Grenze bildeten. Hier offenbart sich ein grundlegender Wandel im Verständnis und der Genese von Grenzen: Bisher waren territoriale Veränderungen auf Grundlage historisch gewachsener Herrschaftsstrukturen vorgenommen worden. So konnten kleinere Herrschaften aber auch größere Gebietskonglomerate zwar durch Tausch, Verkauf, Abtretung oder - wie durch Frankreich praktiziert - als „Reunionen“ die territoriale Zugehörigkeit wechseln. Dabei wurden jedoch die historisch gewachsenen Grenzen beachtet, sogar noch bei der Einrichtung der französischen Départements 1795. Mit der Wahl des Flußverlaufs von Sauer und Our als Grenze zwischen Luxemburg und Preußen wurde dieses Prinzip durchbrochen und ein naturräumliches Gliederungselement als neu geschaffene Grenze gewählt.

The paper considers ‘octroyed’, ‘conceded’ or ‘granted’ constitutions of 19th century Europe whose common roots are to be found in the French ‘Charte constitutionnelle’ of 1814. These Charters stem from a paternalistic process of domestic constitution-making engaged unilaterally by a monarch possessing the de facto constituent power and exercising it without the direct involvement of a body representing the people. Such octroyed constitutions, which are of course to be opposed to democratically established ones, show nevertheless a number of specific characteristics which distinguish them also from ‘imposed constitutions’ in the usual sense. The expression ‘constitutional octroy’ should not be used as a synonym for any process leading to an ‘imposed Constitution’. The contribution aims to develop and to validate or invalidate the value of a series of distinctive criteria and possible elements of a definition of ‘octroyed’ or ‘granted’ constitutions in order to underline their specificity.

Gambling disorder is a well-established behavioural addiction, which was classified with substance-related disorders in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders. Although craving was introduced as a new diagnostic criterion for substance-related disorders, it was not included for gambling disorder. This study aimed to explore the experience of gambling craving and to evaluate whether the elaborated intrusion theory of desire (EIT), a cognitive model of craving, fits gambling craving. A mixed methods study was conducted among 31 non-clinical gamblers. The qualitative part consisted of open-ended questions targeting the components of the EIT. The quantitative part consisted of a questionnaire designed to assess triggers and descriptions of gambling craving. Qualitative analysis revealed six distinct conceptual categories related to gambling craving: positive and negative affect, external cues, mental imageries, thoughts and physiological sensations. The quantitative analysis highlighted the most relevant triggers (e.g. spontaneous thoughts) and experiential characteristics (e.g. visual imagery) of gambling craving. The present study allowed the authors to support the relevance of the EIT as it applies to gambling craving by disentangling its core features. Findings from this study suggest that the use of interventions derived from the EIT may be relevant for problem gambling treatment. [less ▲]

This paper aims to design joint precoding and onboard beamforming of a multiple gateway multibeam satellite system, either in a hybrid space-ground mode, or in a totally on-board one. In such an architecture, with employing high throughput full frequency reuse pattern over both user and feeder links, each gateway serves a cluster of adjacent beams such that the adjacent clusters are served through a set of gateways that are located at different geographical areas. However, such a system brings in two challenges to overcome. First, the interference in both user and feeder links is the bottleneck of the whole system and applying interference mitigation techniques becomes necessary. Second, as the data demand increases, the ground and space segments should employ extensive bandwidth resources in the feeder link accordingly. This entails embedding an extra number of gateways aiming to support a fair balance between the increasing demand and the corresponding required feeder link resources. To solve these problems, this study investigates the impact of employing a joint multiple gateway architecture and on-board beamforming scheme. It is shown that by properly designing the on-board beamforming scheme, the number of gateways can be kept affordable even if the data demand increases. Moreover, Zero Forcing (ZF) precoding techniques are considered to cope with the interference in both user and feeder links which embed in the following premises: (i) each gateway constructs a part of block ZF precoding matrix, (ii) the satellite and gateways perform the precoding scheme, and (iii) a joint design of ZF precoding and on-board beamforming at the payload of the satellite so that no signal processing scheme is conceived at the gateways. The provided simulation results depict the performance gain obtained by our proposed schemes. [less ▲]

In this work, a strategy for the parallelization of a two-way CFD-DEM coupling is investigated. It consists on adopting balanced overlapping partitions for the CFD and the DEM domains, that aims to reduce the memory consumption and inter-process communication between CFD and DEM. Two benchmarks are proposed to assess the consistency and scalability of this approach, coupled execution on 252 cores shows that less than 1\% of time is used to perform inter-physics data exchange.

This contribution frames the notions of inclusion and mental health by describing trends in European societies at the social and economic level that will have direct consequences for a participative civil society and social cohesion. Starting point is the observation that the world faces challenges at the start of the 21st century that are new and unprecedented in its history. The four global forces that break all the trends known so far in human history include urbanization, accelerating technological development, greater global connections, and population ageing. The authors first describe the scale of population ageing, as ageing populations characterize several developed economies. In a second step, they highlight some consequences of population ageing for social welfare and in a third part they elaborate on the notion of justice and inclusion in rapidly changing societies.

The integrative force of the Member States’ status on the judicial function is expressed through the loyalty obligation to provide remedies sufficient to ensure effective legal protection in the fields covered by Union law (Art 19, par 1, subpar 2, TEU). Member States have to ensure access to the national judge, who has been entrusted with a European mandate, and who is in measure to cooperate with the Court of Justice through the preliminary reference procedure. The Member States establish in this way an integrated judicial function. The exercise of such a function by the national judge, in cooperation with the Court of Justice and under the control of the Member State, implies integrative dynamic, which however depends on the balancing exercise with national procedural autonomy and the margin of appreciation of the national judge.
