Ce résultat s'applique notamment à des formes qui ne se relèvent pas en caractéristique zéro, et peut être vu comme la précision d'un aspect du poids dans la généralisation de la conjecture de modularité de Serre aux formes de Hilbert.

Nul n’ignore la grande érudition d’Umberto Eco ni sa curiosité ouvrant son esprit aux plus vastes horizons. C’est pour cette raison que je me suis intéressée aux jeux d’échos qui résonnent dans son œuvre, tout comme à ceux qui peuplent les créations artistiques qui lui rendent hommage. Qu’il s’agisse de littérature, de cinéma, de linguistique, entre autres domaines, les champs qu’explore Eco se construisent en réseaux qui montrent quel prix il a attaché aux œuvres ouvertes. Ce constat me permettra d’organiser ma conférence-projection autour de la question de l’intertextualité (au sens large), en prenant l’exemple du roman Le Nom de la rose, afin de nous diriger en amont vers les Fictions de Borges et en aval vers l’adaptation cinématographique de ce « polar » médiéval qu’a réalisée Annaud.

In time series analysis and other setups, numerous inference procedures need to use residuals, instead of the unobserved errors. In the present paper, we establish general and versatile results regarding the limit of partial-sum processes of ARMAX residuals. Process limits based on residuals often do not correspond to process limits based on the error terms. To illustrate the generality and versatility of our results, we apply them to misspecified ARMA with correlated errors, nonlinear ARMAX, a range of ARMA processes with infinite-variance errors, ARMA with a unit root and a polynomial time-trend, or with seasonal dummy variables to obtain consistency of kernel estimation of the density of ARMAX errors, the asymptotic distribution of statistics useful for CUSUM tests and change-point problem type of tests, and some local power results.

In this presentation we consider the implications of conceptualizing entrepreneurial as the practice of artifactual design. The concept of design draws attention to the interdependence of agency and material artifacts in the entrepreneur's ability to overcome (or not) the constraints of embodied practice and the contingent environment. We develop a conceptual understanding of how the entrepreneur extends the spatio temporal reach of entrepreneurial agency by embedding entrepreneurial purpose in various artifactual forms - forms which then contextualist subsequent activity. In this process also, the future is created as multiple actors create, enact, test, modify, transform and implement these artifactual forms through embodied practice. [less ▲]

Shimura curves arise as a natural generalisation of elliptic curves. As modular curves, they are constructed as Riemann surfaces, and they turn out to have structure of algebraic curve, i.e. they can be described by some algebraic equations with coefficients in some finite extension of Q. Number theorists are interested in the reductions modulo p of these equations. The problem is that these equations are very difficult to compute. I will describe a method to find these reductions without actually knowing the equation. [less ▲]

In our paper, we will demonstrate how a multimodal conversation analytic approach can shed light on the complex phenomenon of joint problem solving in a Mathematics classroom. Through a fine-grained video based single case analysis (Mondada, 2013; Arend et al., 2014), we will show how three children collaboratively solve mathematical problems by mobilizing various resources. They address each other by talking, gazing, gesturing, changing body position as well as by manipulating artefacts. Multimodal conversation analysis allows us to investigate the ongoing organisation of the children’s problem solving activity in its temporal and sequential unfolding as well as to study the multimodally embodied multiparty utterances in their mutual responsiveness (Streeck et al, 2011). Favouring an interactional approach interested in the coordinated achievement of activity (Arend & Sunnen, 2016), we consider that the progress and the outcome of the problem solving activity emerge in situ from the children’s interactions. By relying on multimodal CA, we may point out how the children achieve mutual understanding while accomplishing a task in a Mathematics lesson. Our paper seeks to make a contribution to investigate group-based classroom activities (Mercer et al, 2004) as well as to sensitise teachers to the high complexity of mutually accomplished classroom tasks.

Die wissenschaftliche Beschäftigung mit Grenzen hat Konjunktur. Dies hat nicht nur zahllose empirische Fallstudien zur Folge, ebenso eine dynamische Entwicklung von Konzepten und Denkmodellen, die Grenz(raum)phänomene umfassend erfassen sollen. Dabei zu beobachten ist, dass bewährte Prinzipien der kulturwissenschaftlich orientierten Border Studies oft lediglich neu benannt werden und tatsächliche Innovationen noch ausstehen. In dem Vortrag wird daher der Versuch unternommen, die Praxistheorien aus einer Border-Perspektive zu erschließen und ihr Potential für die kulturwissenschaftliche Grenz(raum)forschung zu diskutieren. Die Praxistheorien, wie sie seit über einem Jahrzehnt in der Kultursoziologie intensiv debattiert werden, erlauben Grenzen in ihren sozialen (Re-)Produktionsprozessen in unterschiedlichen Dimensionen zu untersuchen. Als heuristische Werkzeuge berücksichtigen sie die körperlich-materiale Dimension menschlicher Aktivität und setzen keinen kollektiv geteilten oder territorial determinierten Konsens der Sinndeutung voraus. Vielmehr sehen sie die Unberechenbarkeit des Sozialen vor und interessieren sich für Praxislogiken, d.h. für die in (grenzüberschreitenden) Aktivitäten wirksamen und zugleich hervorgebrachten Wissensordnungen. Weiter bietet die Verdichtung von sozialen Praktiken zu (grenzüberschreitenden) Praxisformationen einen vielversprechenden Ansatzpunkt, um Konzepte wie ‚Grenzlandgesellschaft’ oder ‚Diaspora’ sowohl konzeptionell als auch empirisch ‚anders’ zu fassen. Die im Vortrag vorgestellten Überlegungen bilden die erste Annäherung an eine mögliche praxistheoretische Reformulierung der kulturwissenschaftlich orientierten Border Studies. [less ▲]

Official trilingualism is often drawn upon to portray Luxembourg as a heterogeneous society with high levels of linguistic capital, where multilingualism is declared to be an asset both at individual and societal level. With the increased number and shifted geographic origin of migrants from refugee backgrounds new questions surface concerning the linguistic integration of these new arrivals, who are often incorrectly associated with zerolingualism and whose language capital is seldom perceived as a valuable asset. It has been argued that in contexts of forced migration one cannot talk of second or foreign language learning: migrants are not acquiring the language(s) of the mainstream society for the mere reason of approximating native speakers’ performances; these languages form part of their everyday lived experiences, hence they have to appropriate features that best suit their needs. Accordingly, their full linguistic repertoires constitute single integrated continua that include all the language resources they have learned and accumulated. In line with this and contesting the idea of zerolingualism, we maintain that through a wide variety of trajectories ranging from comprehensive learning to informal encounters with languages, migrants from refugee backgrounds have developed partial, truncated competences in several languages that have resulted in complex linguistic repertoires. Our contribution aims at investigating whether the recognition of multilingualism in Luxembourg entails the acknowledgment of the refugees’ full linguistic repertoires, or on the contrary, it remains limited to the appreciation of official trilingualism and proficiency in standard English. In our analysis we are going to rely on data collected in the context of a French language course for beginners, which is offered to newly arrived migrants by volunteer teachers. Besides commenting on the presence (or absence) of multilingual approaches, we seek to explore whether migrant language features are acknowledged as useful resources and how, if at all, the class draws on the fluid use of all the languages present for both learning and functional purposes. On this note, we aim to determine what is more prominent in this context: the monoglossic perspective where languages are conceived in a linear and compartmentalised way or a repertoire-building approach based on awareness and positive attitudes towards teachers’ and learners’ multilingual repertoires.

Eine häufig sehr enge Verflechtung der Interkulturalitätsforschung mit dem Globalisierungsdiskurs hat dazu geführt, dass komplexe interkulturelle Phänomene, die keinen konkreten Bezug dazu haben, kaum Beachtung finden. Dieser Vortrag soll sich interkulturellen Erscheinungsmustern widmen, die sich vor allem im literarischen Feld zeigen und die in einem lebensweltlich-gegenwartszentrierten Raster nicht erfasst werden und für die andere Beschreibungsmodelle gefunden werden müssen. Im Fokus dieses Vortrags soll der Bereich der literarischen Antiken-Rezeption stehen, die mit der Romantik nicht mehr eindeutig als Fortschreibung einer Traditionslinie und „epigonale[ ] Bewahrung der tradierten Muster“ (Riedel) gesehen werden kann. Vielmehr setzt hier – bspw. bei Friedrich Schlegel – eine Distanzierung ein, die Hellas und Rom zu einem Anderen und damit deren literarische Repräsentation für interkulturelle Fragestellungen interessant macht. Besondere Beachtung verdient der Bereich auch deshalb, weil Bezugnahmen auf die griechisch-römische Antike grundsätzlich im intermediären Bereich von Eigenem und Fremdem zu verorten sind und damit in spezifischer Art und Weise als interkulturelles Phänomen gelten können. Überlegungen zur Beschreibung der Antiken-Rezeption als komplexem interkulturellen Phänomen sollen vor allem anhand von Texten aus der Zeit um 1800 angestellt werden. [less ▲]

Our contribution aims at investigating the communication challenges brought by a rather abrupt and recent change in Luxembourg’s refugee intake patterns, reflected in the increased number and shifted geographic origin of international protection applicants. We have adopted a border studies approach to explore the new linguistic and social reality, which emerges through continuous interactions between the diverse, mobile and multilingual society of Luxembourg, on one hand, and on the other hand, the linguistic and cultural repertoires that recently arrived asylum seekers – mostly Syrians, Iraqis and Afghanis – bring to this context. We argue that theoretical and applied knowledge generated by previous research on multilingualism in cross-border regions is transferable to this new field of inquiry. [less ▲]

Since 1958 a series of new reform programmes, known as “New Math reform” tried to fundamentally deconstruct the mathematics education of schools in the United States. This reform aimed to promote the “problem-solving” abilities in students and was a means to modernise not just the school math education but also the idea of why students should learn mathematics. Later, the reform project travelled to Europe through the support of the OECD and some other international or European organisation. This paper briefly reviews the process of the adaptation of this reform project in Luxembourg during the 1960s and 1970s. The aim is to look at how the ideological background about mathematics education, and in general education, mattered in the preceding of this school reform. [less ▲]

This contribution aims at investigating the language policies that are in place in Luxembourg to support the linguistic integration of adult migrants from refugee backgrounds. A rather abrupt and recent change in the country’s refugee intake patterns -reflected in the increased number and shifted geographic origin of international protection applicants- is presenting new challenges for the process of integration and the actors involved. Language is a crucial aspect for inclusion and participation in working and social life, especially in highly diverse, mobile and multilingual contexts such as Luxembourg. It has been demonstrated that in multilingual environments people are more likely to establish effective ways of communication without sharing a common language code, principally through the productive-creative combination of all available language and other communication resources. Against this background, the present contribution examines the presence (or absence) of multilingual approaches in local policies for linguistic integration and language learning. In this connection, I am going to explore whether the inclusion of multilingualism entails the acknowledgment of the asylum applicants’ full linguistic repertoires, or whether it remains limited to the appreciation of those languages that are generally recognized in our context such as French, English, German or Luxembourgish. Similarly, the purposes and forms of available linguistic training are going to be discussed, with particular focus on the organization of formal language education, language training for low educated and illiterate asylum applicants, policy measures for the support of informal/non-formal language learning activities, and potential integration of language learning with professional development and social participation. Main policies at national and organizational level are going to be reviewed and commented on using interview data from key actors involved in the process. The aim is to offer different perspectives on the linguistic integration of adult migrants from refugee backgrounds in Luxembourg. [less ▲]

In the standard paradigm of isogeometric analysis, the geometry and the simulation spaces are tightly integrated, i.e. the same non-uniform rational B-splines (NURBS) space, which is used for the geometry representation of the domain, is employed for the numerical solution of the problem over the domain. However, there are situations where this tight integration is a bane rather than a boon. Such situations arise where, e.g., (1) the geometry of the domain is simple enough to be represented by low order NURBS, whereas the unknown (exact) solution of the problem is sufficiently regular, and thus, the numerical solution can be obtained with improved accuracy by using NURBS of order higher than that required for the geometry, (2) the constraint of using the same space for the geometry and the numerical solution is particularly undesirable, such as in the shape and topology optimization, and (3) the solution of the problem has low regularity but for the curved boundary of the domain one can employ higher order NURBS. Therefore, we propose to weaken this constraint. An extensive study of patch tests on various combinations of polynomial degree, geometry type, and various cases of varying degrees and control variables between the geometry and the numerical solution will be discussed. It will be shown, with concrete reasoning, that why patch test fails in certain cases, and that those cases should be avoided in practice. Thereafter, selective numerical examples will be presented to address some of the above-mentioned situations, and it will be shown that weakening the tight coupling between geometry and simulation offers more flexibility in choosing the numerical solution spaces, and thus, improved accuracy of the numerical solution.

In the standard paradigm of isogeometric analysis [2, 1], the geometry and the simulation spaces are tightly integrated, i.e. the non-uniform rational B-splines (NURBS) space, which is used for the geometry representation of the domain, is also employed for the numerical solution of the problem over the domain. However, in certain situations, such as, when the geometry of the domain can be represented by low order NURBS but the numerical solution can be obtained with improved accuracy by using NURBS of order higher than that required for the geometry; or in the shape and topology optimization where the constraint of using the same space for the geometry and the numerical solution is not favorable, this tight coupling is disadvantageous. Therefore, we study the effect of decoupling the spaces for the geometry representation and the numerical solution, though still using the prevalent functions in CAD/CAGD. To begin with, we perform the patch tests on various combinations of polynomial degree, geometry type, and various cases of varying degrees and control variables between the geometry and the numerical solution. This shows that certain cases, perhaps intuitive, should be avoided in practice because patch test fails. The above-mentioned situations are further explored with some numerical examples, which shows that weakening the tight coupling between geometry and simulation offers more flexibility in choosing the numerical solution spaces.

The present course will focus on intergenerational family relations over the life-span from the perspective of developmental psychology. In the first section, we will have a closer look at central definitions, models and concepts from life-span developmental psychology–for instance, life-span models of development, structuring the life course, developmental tasks, normative and non-normative life events, and the concept of generation. In the second part, we will focus on key concepts in the study of intergenerational family relations, such as intergenerational solidarity, conflict and ambivalence. Further, specific research evidence regarding intergenerational relations over the life span (including adolescent-parent, adult child-parent as well as grandchild-grandparent relations) will be presented and discussed, also taking into account cross-cultural aspects and intergenerational relations in the context of migration.

The course will present an overview of recent developments, which will enable students to make informed choices in terms of discretization and model selection in solving numerical problems in mechanics. We will cover discretization strategies ranging from the standard finite element method, the smoothed finite element method, the extended finite element method, polygonal and virtual element methods, meshfree methods. The applications range between fracture of heterogeneous materials and biomedical simulations. The intended learning outcomes of the course are such that the students will be: - able to critically assess discretization schemes in mechanics - able to implement simple error estimators for finite element methods - familiar with basic multi-scale methods for fracture and their limitations - able to follow basic literature in model error and model selection, in particular based on Bayesian inference Course participants will learn these topics through lectures and hands-on numerical experiments.

Ageing and migration have become key issues in many European countries today, as a large number of first generation immigrants of the 1970s are currently approaching retirement age. In this context, also questions regarding the intergenerational relations and intergenerational solidarity between first generation parents and their adult children - who have grown up in the host country - have gained high importance. Although the idea of return migration might often be well present in the lives of ageing migrants, an actual permanent return to the country of origin seems to be enacted more seldom, especially when the own children have settled down permanently in the receiving country. It is therefore of prime importance to learn more about the particular needs and resources of older migrants and their families. Ageing migrants face undoubtedly a special situation: The acculturation situation may result in an increased need for social support due to fewer sociocultural resources in the host country. Within migrant families, an acculturation gap between first and second generation might further lead to different expectations regarding intergenerational solidarity and support, and this can cause intergenerational strain and have negative effects on well-being of the different family members. The present training session will address issues of relationship quality (such as solidarity, conflict, ambivalence) as well as aspects of intergenerational value transmission between ageing first generation parents and their adult children in the context of migration. Both theoretical considerations as well as results from a recent study on Portuguese immigrant families in Luxembourg (IRMA – Intergenerational Relations in the Light of Migration and Ageing, funded by the Fonds National de la Recherche Luxembourg) will be presented and discussed.
