The discrete Pompeiu problem is stemmed from an integral-geometric question on the plane. The problem is whether we can reconstruct a function if we know the average values of the function on every congruent copy of a given pattern. After introducing the theory of spectral analysis on discrete Abelian groups, I show some results for the discrete version of the problem. One of the arguments is connected to a coloring problem of the plane. One of them is a geometric construction and some others based on some geometric and combinatoric properties of the plane. I also mention some unsolved questions of the topic. My talk is based on a joint work with M. Laczkovich and Cs. Vincze. [less ▲]

Series of workshops tailored towards early-career researchers in Luxembourg explaining the publishing process and how Open Access fits in the traditional journal-subscription based model. The idea is to break some of the myths around OA (e.g. OA is a journal, OA is only possible the gold way) by presenting the 'Green' (self-archiving) and 'gold' (paying Article Processing Charges) routes. Some of the benefits are presented, along with the main Luxembourgish funder FNR's mandate. The presentation uploaded was given to PhDs and post-docs from the Luxembourg Institute of Health on 13/12/2017. [less ▲]

This paper argues for a hybrid approach to historical research that combines ’traditional’ with digital hermeneutical approaches in a new practice of doing history. As the digital turn alters and affects all parts of the historical research process, this is a pressing challenge and need for all historians, not just for those engaged in ‘big data’ projects. Indeed, hybridity is, and should be, the new normal. Yet while most historians are accustomed to deploying digital approaches in the information gathering stage of their research, they often refrain from ‘going digital’ in its processing and especially analysis stages. Describing a number of digital tools used in work done on the diaries of Anne frank, the paper critically analyses and demonstrates the added value of incorporating them in all stages of historical research. Digital approaches enhance the methodological repertoire furnished by ‘traditional’ close reading practices. Hybrid approaches thus expand our intellectual horizons and the analytical power we bring to bear upon our sources. [less ▲]

Due to the separation between the historical and legal fields which have examined the issue of WWII reparations, no generally accepted definition of their current status exists either in the historical, legal or political spheres. This lack of clarity has greatly contributed to this issue remaining unresolved until the present. In his talk, Spero Paravantes looks at the way the issue was used by the Big Three in their dealings with each other after WWII. In light of the Greek government’s continued pursuit of WWI and WWII debts it claims are owed by Germany, and the recent claims made by the Polish government, this talk summarizes the historical, legal and political scholarship on the issue and also comments on its effect on relations between members of the Eurozone and the way in which responses to the issue of WWII reparations, and indeed the legacy of the war itself, have brought political and cultural divisions within the Eurozone again to forefront.

Dr Paravantes' presentation, " European Migrations post-WWII: Past, Present and Future, " will discuss the history of migrations and migration/refugee policy within the EU, from the beginning of the integration process and the formation of the European Coal and Steel Community (ECSC) until the present. The talk will focus on earlier migrations within Western Europe, the rules established to regulate internal and external migration, and the steps which the various iterations of the European Union and its individual members took to deal with them. The overarching objective of this presentation is to place current events, and reactions to them, into the context of European integration and to examine misconceptions about migration policy and borders in the EU.

We investigate the class of binary associative and quasitrivial operations on a given finite set. Here quasitriviality (also known as conserva-tiveness) means that the operation always outputs one of its input values. We also examine the special situations where the operations are commutative and nondecreasing. In the latter case, these operations reduce to discrete uninorms, which are discrete fuzzy connectives that play an important role in fuzzy logic. As we will see nondecreasing, associative and quasitrivial operations are chara-cterized in terms of total and weak orderings through the so-called single-peakedness property introduced in social choice theory by Duncan Black. This will enable visual interpretaions of the above mentioned algebraic properties. Motivated by these results, we will also address a number of counting issues: we enumerate all binary associative and quasitrivial operations on a given finite set as well as of those operations that are commutative, are nondecreasing, have neutral and/or annihilator elements. As we will see, these considerations lead to several, previously unknown, integer sequences. [less ▲]

Previous language attitude models assign a privileged status to language behavior as important factor that influence speaker evaluations. Moreover, language is framed by extra-linguistic cues (e.g., speaker’s social group membership) that may affect evaluative outcomes (e.g., Myers-Scotton, 2006). In previous research, a conceptual overlap exist between the evaluations of languages, nationality groups, and individual speakers. Consequently, the distinction between language and nationality attitudes has not been addressed. Moreover, dual-process theories argue that people hold two types of attitudes towards the same object, an explicit and an implicit attitude (e.g., Wilson, Lindsey, & Schooler, 2000). Thus, we examined whether language and nationality attitudes affect speaker evaluations, both on an explicit and implicit level. Explicit assessments were examined with questionnaires and implicit assessments were measured with audio Implicit Association Tests and an affective priming task. Our study findings (N = 79) in Luxembourg, a linguistically diverse country with three official languages, revealed that implicit nationality attitudes significantly predicted implicit speaker evaluations such that a stronger implicit preference for the Luxembourgish national group was associated with an increase in the preference for speakers of the Luxembourgish national group. This implicit in-group favoritism is discussed in the light of its implications for future research. [less ▲]

Die internationale Ausrichtung von Städten wirkt sich vielfach als Problem für Wohnungsmärkte aus. Die steigende Nachfrage führt zu Angebotsverknappungen und direkten wie indirekten Folgeeffekten im Markt insgesamt. Auf diese Weise entwickelt sich das Wohnungswesen zunehmend kritisch. Der Beitrag diskutiert dieses Problem am empirischen Beispiel Luxemburgs, einem stark internationalisierten Kleinstaat und bedeutenden Finanz- und EU-Standort. In Luxemburg gilt der Erwerb von Wohneigentum zwecks Wertsteigerung nach wie vor als Credo einer stark liberalistisch geprägten, konservativen Wohnungsbaupolitik. Zugleich stellt dies für viele Luxemburger als auch für die stetig wachsende Anzahl der im Großherzogtum ansässigen Ausländer die Grundlage für lukrative Vermögensanlagen dar. Seit der globalen Finanz- und Wirtschaftskrise steht die Anwerbung ausländischer Investoren zunehmend auf der wirtschaftspolitischen Agenda. Die ökonomische Stabilität des Landes und die relative Sicherheit von Immobilieninvestitionen fördern diese Entwicklung. Öffentlicher Wohnungsbau ist nach wie vor eine Randerscheinung. Die einzige Antwort, die in dieser Situation zu einem Konsens führt, sind Baulückenprogramme, verdichtetes Wohnen und urbane Großprojekte. Diese profitorientierte Wirtschaftsentwicklung ist im europäischen Kontext nicht einzigartig. Sie führte jedoch in diesem spezifischen Fall in der Vergangenheit zu beispiellosen Folgen: Bezogen auf die geringe Größe des Landes und im Licht eines starken, primär migrationsbedingten Bevölkerungsanstiegs, wachsender Einkommensunterschiede und einem immer stärker werdenden Nachfrageüberhang, wird bezahlbarer Wohnraum zunehmend knapp. Dieser Trend zeichnet sich nicht nur im Ballungsgebiet der Hauptstadt ab, sondern indes auch in ländlich geprägten, peripheren Gebieten des Kleinstaats. Bisher vorherrschende Machtverhältnisse, Ideologien und Kulturen geraten immer mehr unter Druck. Spannungen zwischen Mehrheiten und Minderheiten, Eigentümern und Mietern werden immer deutlicher, aber deren Aushandlung spielt sich oftmals in einem Vakuum ab. Die Verschuldung der Haushalte steigt weiter an. Nach der globalen Finanzkrise haben sich jedoch einige bottom-up Wohnungsbauinitiativen gegründet. Sie tragen dazu bei, den Diskurs über die Wohnungsfrage öffentlich auszutragen und bieten somit die Chance für die Etablierung von alternativen Wohnmodellen. Die Aushandlungsprozesse um diese neuen Bewältigungsstrategien finden jedoch statt in einem Setting, in dem die Devise „der Markt wird es schon richten“ seit Jahren die Politik (beg)leitet. Ihre Implementation ist langwierig. Die Kombination von sozioökonomischen Rahmenbedingungen, starken Interessengruppen sowie informellen Arrangements hat zu institutionellen Lock-Ins geführt, die eine Hürde für die Etablierung von Alternativen darstellen.

Parmi les multiples notions ou perspectives à travers lesquelles les processus de recomposition des solidarités peuvent être appréhendées, celle de l’inclusion joue aujourd’hui (intensifié par CPDH, 2006) un rôle primordial, y compris dans les domaines du travail social. Selon Ebersold (2009), les discours sur l’inclusion tendent à reconfigurer la légitimité des institutions socio-éducatives et à réadapter leurs rôles et missions en faveur d’une société plus inclusive. Dans la perspective des droits de l'homme, l’inclusion est vue comme un outil ou un moyen approprié pour atteindre l’objectif de la création d’une société dite inclusive, où la non-discrimination, l’égalité des chances et la pleine et égale jouissance de tous les droits de l’homme et de toutes les libertés fondamentales par les personnes en situation de handicap vont de soi (Limbach-Reich, 2015; Gardeou, 2012). A côté du terme d’inclusion scolaire, le terme d’inclusion sociale n’était toutefois que d’un emploi rare dans le langage politique en Europe avant l’émergence de la Stratégie de Lisbonne (2000). Il a poursuivi sa progression triomphante dans le système économique du néolibéralisme et a été remplacé par celui d’inclusion active en insistant sur le principe «pas de droit sans devoir» (Euzéby, 2010). En travail social, la réception du discours sur l’inclusion et la participation sociale, en particulier dans le contexte du handicap, consiste souvent à déterminer les différences qui semblent exister entre intégration et inclusion (Plaisance, et al. 2007), mais n'aborde pas l'utilisation ambivalente de la terminologie et ne pose pas la question du pouvoir et du (manque de) solidarité (Becker, 2016). En ce qui concerne le Luxembourg, le discours de la CPDH entre de plus en plus en conflit avec une gouvernementalité (Foucault, 2004) basée sur le néolibéralisme, qui considère les personnes handicapées comme «capital humain» auquel il faut faire acquérir le habitus (Bourdieu, 1997) du «protean worker» (Lifton, 1993). Cette évolution tend à créer des inégalités dues aux mérites, qui sont considérées comme justes même en cas de personnes handicapées et en conséquences aliment l'exclusion sociale par le processus de gestion les difficultés comme problèmes individuelles à guérir par et en travail social (Hamzaoui, 2015). Dans la méritocratie néolibérale, l’intervention sociale est en plus en danger de devenir un organe de contrôle (cf. Staub-Bernasconi, 2007) sous le sceau de l’inclusion qui légitime l’exclusion des personnes perçues comme étant incapables de bénéficier d’une éducation «normale» et d’être compétitifs sur le marché du travail. L'objet de cette présentation est d’examiner les conséquences de la politique d’inclusion en faveur des personnes en situation de handicap. [less ▲]

In this overview talk, we will illustrate the arithmetic significance of the coefficients of modular forms, from classical examples to the modern point of view of Galois representations. From that on, one is naturally lead to questions on the distribution of the coefficients in various senses. We will briefly touch on some of them, report on recent theorems and state some open questions. When investigating arithmetical properties of coefficients through Galois representations, their ramification properties are an important object to study. One notices that forms of -so called- weight one play a special role that will be explained. The importance of Galois representations coming from modular forms is that one expects all Galois representations satisfying reasonable "geometric" assumption to arise in such a way. As a special case, we will explain the theorem of Khare and Wintenberger, formerly called Serre's modularity conjecture, and conjectural generalisations. Whereas Galois representations are usually very hard to calculate directly on a computer, modular forms are pretty simple to compute. We will briefly touch on this and what kind of information one can get. If time allows, we will also touch on an application to the so-called inverse Galois problem. [less ▲]

The number of foreigners living in Luxembourg is still rising and represents today about 48% of the inhabitants. This study focuses on the description and mapping of the place of residence for the different nationalities living in Luxembourg. It seeks to underline differences through indicators built from the 2011 census data. We focus on the territorial distribution of the different nationalities by taking into account the urban structure and distance to jobs. If differences according to nationalities in the residential behavior of households can be empirically identified they may raise issues of spatial equity and (un)equal accessibility to job market. We analyse whether the geographic location of different nationalities in Luxembourg is linked to urbanisation level, the distance to the “poles d´emploi” or general accessibility to jobs. [less ▲]

Aufgrund der sozioökonomischen und räumlichen Entwicklung des Großherzogtums ist der luxemburgische Wohnungsmarkt seit mehr als zwei Jahrzehnten vor allem durch ausgeprägte und dauerhafte Knappheiten und hohe Kauf- und Mietpreise gekennzeichnet. Etliche Städte und Metropolregionen in Europa zeigen ähnliche Tendenzen auf. Spezifisch für unseren Fall sind jedoch erstens die geringe Größe des Landes sowie zweitens die fortwährenden wirtschaftlichen und demografischen Dynamiken, sie sich zum Teil in sehr starken grenzüberschreitenden, internationalen und sogar globalen Verflechtungen ausdrücken. Die Relevanz der „Internationalisierung“ des Wohnens in (und um) Luxemburg in all ihren Facetten ist allerdings nicht nur aus politischer und soziokultureller Sicht gegeben. Wegen seiner Besonderheit war der Fall in der Vergangenheit auch immer wieder Gegenstand wissenschaftlicher Untersuchungen. Bis auf einige wenige Ausnahmen waren diese Studien meist quantitativ angelegt und beschränkten sich vor allem auf die durch die sozioökonomischen Entwicklungen verursachten räumlichen Effekte der Internationalisierung des Wohnens. So wurden zwischen seit Mitte der 2000er Jahre z.B. mehrere Studien über Grenzpendlerströme und deren Auswirkungen auf das Wirtschaftswachstum, die Mobilität und das Wohnen in Luxemburg durchgeführt. Auch das Ausmaß und die Beweggründe für den Abzug von im Großherzogtum lebenden luxemburgischen und ausländischen Bürgern in das grenznahe Ausland wurde im Detail erforscht. Der luxemburgische Immobilienmarkt ist durch eine sehr dynamische Entwicklung und einen hohen Grad an Internationalität gekennzeichnet ist. Unser Beitrag zielt hauptsächlich darauf ab, die bisher vorherrschende wissenschaftliche Debatte über die Frage der Internationalisierung des Luxemburger Wohnungsmarktes erneut zu öffnen und sie um den Aspekt der Governance zu erweitern. Auf diese Weise sollen einerseits der Begriff der „Internationalisierung“ mit seinen z.T. sehr unterschiedlichen Wirkungsweisen im Bereich des Wohnens in Luxemburg differenzierter ergründet und andererseits neue Forschungsansätze entwickelt werden. Unsere Aussagen beruhen im Wesentlichen auf der Auswertung von Dokumenten und Sekundärmaterial zum Thema sowie der aktiven Mitwirkung an relevanten Fachdiskussionen zum Thema Wohnen in Luxemburg.

Luxembourg’s steadily growing economy attracts many migrants from all over the globe. As a result, the country’s trilingualism is being replaced by a more complex multilingualism with a growing importance of English. The paper gives a quick overview of the historic evolution based on sociolinguistic surveys of 1984, 1997 and 2008, followed by an in-depth description of today’s situation based on two language related questions of the Luxembourgish census 2011: Which language do you know the best? Which languages do you speak on a regular basis at home, at school and at work? The census data tell how many people use English in different contexts and who these people are. The focus will be on the language situation at work. A correspondence analysis reveals strong correlations between languages and occupations reflecting a split of the labour market: English dominates in high skilled jobs in the private sector, whereas Portuguese is the main language in low skilled jobs in the private sector, and Luxembourgish is the main language in the public sector. French and German are used more evenly across all occupations and sectors. These results highlight the link between the use of languages and competing social positions. [less ▲]

Let p be a fixed prime number. It has been known for a long time that there are only finitely many Galois extensions K/Q with Galois group a finite irreducible subgroup of GL_2(F_p^bar) that are imaginary and unramified outside p. In contrast, there are infinitely many such with Galois group inside GL_2(Z_p^bar), even if one restricts to ones coming from modular forms (this restriction is believed to be local at p). It is tempting to ask what happens "in between" F_p^bar and Z_p^bar, i.e. whether there is still finiteness modulo fixed prime powers. In the talk, I will motivate and explain a conjecture made with Ian Kiming and Nadim Rustom stating that the set of such Galois extensions `modulo p^m' (a proper definition will be given in the talk) coming from modular forms is finite. I will present partial results and a relation of the finiteness conjecture to a strong question by Kevin Buzzard. The talk is based on joint work with Ian Kiming and Nadim Rustom. [less ▲]

This project explores the issue of immunities of Heads of State and State officials for international crimes before international courts and international criminal tribunals and courts. My presentation begins with the Rome Statute provisions and the International Criminal Court’s case law on the issue; it then turns to the jurisprudence of the international criminal tribunals and specialised, internationalised, hybrid courts, in an attempt to provide a concise but as far as possible comprehensive analysis; it proceeds with an analysis under public international law and the International Court of Justice (hereinafter ‘ICJ’) case law. As the question of immunities is currently under review at the International Law Commission (hereinafter ‘ILC’), an analysis of the ILC Reports thus far is included. Finally, the project will address the question of how national courts and national law have dealt with Article 27 of the Rome Statute [less ▲]

Today's decision makers in fields ranging from engineering to psychology, from medicine to economics and/or homeland security are faced with remarkable new technologies, huge amounts of information to help them in reaching good decisions, and the ability to share information at unprecedented speeds and quantities. These tools and resources should lead to better decisions. Yet, the tools bring with them daunting new problems: the massive amounts of data available are often incomplete, unreliable and/or distributed and there is great uncertainty in them; interoperating/distributed decision makers and decision making devices need to be coordinated; many sources of data need to be fused into a good decision; information sharing under new cooperation/competition arrangements raises security problems. When faced with such issues, there are few highly efficient algorithms available to support decision makers. The objective of Algorithmic Decision Theory (ADT) is to improve the ability of decision makers to perform well when facing these new challenges and problems through the use of methods from theoretical computer science, in particular algorithmic methods. The primary goal of ADT is hence to explore and develop algorithmic approaches for solving decision problems arising in a variety of applications areas. Examples include, but are not limited to: - Computational tractability/intractability of social consensus and multiple criteria compromise functions; - Improvement of decision support and recommender systems; - Development of automatic decision devices including on-line decision procedures; - Robust decision making; - Learning for multi-agent systems and other on-line decision devices. This presentation will focus more specifically on multiple criteria decision aiding methodology, the actual research field of the author. [less ▲]

Dans cet exposé, je vais donner les idées principales de mon travail avec Mladen Dimitrov dans lequel nous démontrons que la représentation galoisienne associée à toute forme modulaire de Hilbert de poids un en caractéristique p et de niveau premier à p est non-ramifiée en p. 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.

The conference “Benelux, Europe and the Cold War, the power of non-powers”, which took place on 30 and 31 March 2017 at the University of Luxembourg, was the first of three events planned in the FNR-funded CORE junior project “Benelux”, as part of its public outreach and academic output objectives. The conference sought to highlight asymmetrical power relations in the Cold War period of European integration by examining European security. What was/is European security in the context of the Cold War? How was and is it conceived? What role did “non-powers” play in European security, and how did they help define it? This conference investigated these and other related questions by re-examining the US/European relationship in the early Cold War and the role that developments during this period played in the European integration movement. In so doing, the conference also showcased findings which helped unify historiographies of the Cold War and European integration. [less ▲]

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.

Many studies have shown that humans can easily extract numerical characteristics of single digits such as numerical magnitude and parity status. We investigated whether spontaneous processing of magnitude or parity status can be observed when participants are passively presented with sequences of briefly displayed Arabic digits. We assessed the parity processing by presenting seven odd digit numbers followed by one even digit (and reverse) with a sinusoidal contrast modulation at a frequency of 10HZ in one-minute sequences. The same paradigm and frequencies were used to investigate magnitude processing (i.e. seven digits smaller than five followed by one digit larger than five; and reverse) and control condition (i.e. sequence of 1-4-6-9 followed by 2-3-7 or 8). We observed a strong EEG activation on right parietal electrodes and a weaker activation on left parietal electrodes in all conditions. Left and right activations were stronger in the parity than in the other conditions, reflecting an automatic retrieval of parity information conveyed by the Arabic digits. The weaker activation during the magnitude task could reflect a more complicated access of the information corresponding to magnitude status. Right activations during the control task could be due to the fact that subjects can quickly learn to categorize numbers arbitrarily. These neuronal activation patterns are consistent with the neuro-imaging literature describing the localization of basic numerical processing. Our findings indicate that magnitude and parity status are extracted automatically from Arabic digits, even when numerical stimuli are presented without instructions at a high presentation rate.

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.
