Social service providers in the Greater Region report that many children in need of special care and social assistance find themselves in cross-border situations. The legal regulations and practices for the care of children and adolescents can vary considerably from country to country. This can cause delays, breaks or deterioration in the quality of support and sometimes irreversibly worsen the child's situation. Depending on the situation, diagnoses and access to social, medical-social or legal services can change considerably. The EURQUA project deals with cross-border child protection and disability rights within a multinational perspective. [less ▲]

Recent developments in DOLFINx allow for the block assembly of linear algebraic systems arising from discretisations of coupled partial differential equations. Each algebraic block represents a subproblem associated with a coupling of the unknown fields. Designing and implementing robust and scalable solution and preconditioning strategies for block-structured linear systems is an active area of research. In this contribution we show how DOLFINx can now exploit one of the most significant features of PETSc; the dynamic composition of the hierarchical solver and preconditioner options at runtime, see Brown et al [1]. The idea is inspired by the work of Kirby and Mitchell [2] that was originally implemented in the Firedrake Project. One of the most significant benefits of the approach is the possibility to construct advanced preconditioners that require structure beyond a purely algebraic problem description, eg the pressure-convection-diffusion (PCD) approximation of the Schur complement for the Navier–Stokes equations, see Silvester et al [3]. We illustrate the capabilities of our implementation on examples ranging from incompressible flow of a viscous fluid, through temperature-driven convection, to flows described by rate-type viscoelastic fluid models.

Presentation of the workshop : To mark the International Day of Women Rights, the University of Luxembourg is organizing an online workshop on Women in Computing. ICT is today one of the most gendered-divided fields. Gendered stereotypes suggesting that men are more interested in ICT are still active in shaping attitudes. However, this inequality has only started in the 80s. For instance, by 1943, in the USA, almost all people employed in computing were women. It is was common to believe that "programming requires lots of patience, persistence and a capacity for detail and those are traits that many girls have". The speakers of this workshop will shed light on the historical role of women in computing to help us understand how to improve gender inequality in ICT. [less ▲]

In this talk I will sketch the development of an EAP curriculum at the University of Luxembourg Language Centre that takes into account multilingualism, needs analysis, insights into EAP teaching and materials, discussions with stakeholders, and human resources. I will argue for an EAP curriculum approach that trains a set of core skills and enables discipline-specific genre and language learning through awareness-raising activities and corpus search tools. In this view, English for Specific Academic Purposes is not the teaching of disciplinary vocabulary. Instead, teachers use their EAP expertise to ascertain disciplinary needs, compose or evaluate materials, set tasks in line with disciplinary activities, and –importantly- provide the skills and tools to continue (discipline-specific) learning beyond the course. I will draw on examples of EAP course design from my own practice as well as on findings from my published research into EAP coursebook authenticity and multilingual course design. [less ▲]

In this presentation we focus on how lecturers mark important information in their lectures. Being able to identify important information is fundamental to the learning process (Benson, 1989, p. 437), and the different levels of information in a lecture may be highlighted through a careful choice of language, including explicit macro markers (Chaudron & Richards, 1986; Allison & Tauroza, 1995; Jung, 2003; Titsworth & Kiewra, 2004). Previous research has focussed particularly on importance markers in native speaking (NS) lecturer discourse (e.g. Crawford Camiciottoli 2004; Deroey & Taverniers 2011, 2012; Deroey 2012, 2014, 2015). Our study expands this research to compare the use of lexicogrammatical importance markers in both NS and non-native speaker (NNS) lectures. A specially compiled corpus of about 365,000 words of Physical Science lectures was used in our study, featuring a balanced number of words from lectures in Italy (Johnson & Picciuolo, 2020; Picciuolo & Johnson, 2020) as well as in New Zealand, the UK and Malaysia (‘Engineering Lecture Corpus’ ). A qualitative analysis was done to annotate all instances of markers evaluating the importance of lecture content. These included verb, adjective or noun phrases containing an evaluation of importance. Assessment-related expressions were also marked. 378 separate instances were identified. More delicate analysis of the importance-marking phrases was done, with distributions and variations in frequent patterns identified in both NS and NNS lectures. While Verb phrases were found to be the most frequent in both NS and NNS lectures (62%), there was variation in the type of Verb patterns according to NS and NNS, as well as in verb choice. In general, though importance markers were distributed evenly over NS (=191) and NNS (=187) lectures, NS showed more variety than NNS in the type of pattern used, with adjective, metanoun and assessment-related expressions as well as idiomatic expressions figuring more frequently than in NNS, although there were significant differences also within the NS and NNS sub-corpora themselves. Whether these findings show that NNS are more aware of the risks of misunderstanding among their international student audiences (House, 2003; Mauranen, 2006), and thus use a smaller variety of less ambiguous importance markers, or that NNS have fewer language resources to draw on in the first place, awareness-raising among EMI lecturers is vital when preparing teacher training materials, given the expansion of ELF in international academic contexts where both lecturers and students are non-native speakers.

«Ambitious Amateurs» vise à enquêter sur le soi-disant goût de masse à travers le prisme de la pratique culturelle participative du tournage dans les longues années 1960. Les cinéastes étaient des consommateurs d'un média qu'ils co-créaient eux-mêmes. Ils produisaient pour un cercle de pairs, respectivement pour obtenir la reconnaissance des professionnels. La forme esthétique de ces films et genres, l'excès de sens, ainsi que les idéaux politiques moraux représentent les axes centraux de l'analyse. En outre, les relations entre les membres du club et leurs activités dans les associations faîtières nationales ainsi que les contextes de rencontres transnationales (par exemple l'UNICA, fondée en 1937) doivent être davantage observés. Celui-ci sera exécuté sur les exemples de clubs et de lieux sélectionnés au Luxembourg, en Belgique, en France et en Allemagne. Outre la recherche d'archives et l'histoire orale, les documents cinématographiques eux-mêmes sont la pièce maîtresse de l'analyse. Le sujet est particulièrement pertinent pour la culture générale et l'histoire des médias, en raison de l'évolution historique des tendances à la censure et à l'autocensure concernant la permissivité sexuelle, le militantisme politique ou les déclarations religieuses dans les années 1960. Celles-ci seront liées à la question de l'américanisation, respectivement du rejet de cette dernière dans le discours des créateurs de films européens et de la presse d'actualité. La comparaison internationale facilitera en outre l'affichage des spécificités nationales et des diverses temporalités au sein de l'Europe (occidentale). Simultanément, une possibilité de concevoir certains développements transnationaux potentiels - également au-delà du «rideau de fer» - sera générée. [less ▲]

The European Communities (founded in 1951) with the ECSC and then the European Union started out as an exclusively west European enterprise. The guarantee of the “rule of law” was one of the criteria for accession to the European Union which the EU defined at the Copenhagen European Council in 1993, together with stability of institutions guaranteeing democracy, human rights, and respect for and protection of minorities. the existence of a functioning market economy as well as the capacity to cope with competitive pressure and market forces within the Union. Membership presupposes the candidate's ability to take on the obligations of membership including adherence to the aims of political, economic and monetary union. In their Constitutions today, all the countries of Central and East Europe confess to the “rule of law” as either a fundamental prerequisite or one of the highest values/a fundamental value of the constitutional order as stated (by Czech Republic, Slovakia, Slovenia, Poland), or by declaring their country operates under or is based on the “rule of law” as stated (by the Baltic countries, Hungary), or that it is a “law-governed state” as stated by (Bulgaria; Romania). In doing so, the countries confess to the “rule of law” at least in its formalistic understanding.The crucial question is what the “rule of law” as referred to by the EU in the Copenhagen Criteria and by the Constitutions of the countries of Central and Eastern Europe effectively means. What is the state practice? [less ▲]

Processing high-throughput data-streams has become a major challenge in areas such as real-time event monitoring, complex dataflow processing, and big data analytics. While there has been tremendous progress in distributed stream processing systems in the past few years, the high-throughput and low-latency (a.k.a. high sustainable-throughput) requirement of modern applications is pushing the limits of traditional data processing infrastructures. This paper introduces a new distributed stream data processing engine (DSPE), called “Asynchronous Iterative Routing” or simply AIR, which implements a light-weight, dynamic sharding protocol. AIR expedites a direct and asynchronous communication among all the worker nodes via multiple Message Passing Interface (MPI) communication channels and thereby completely avoids any additional communication overhead with a dedicated master node. With its unique design, AIR scales out to clusters consisting of up to 8 nodes and 224 cores, performing much better than existing DSPEs, and it performs up to 15 times better than Spark and Flink in terms of sustainable-throughput.

In this PhD outline, I will present highlights from my PhD research project on mathematical modelling with real-world information in the classroom, remote teaching and outdoor learning in Luxemburg. Through design-based explanatory studies, I investigated different technology enhanced tasks, learning and teaching settings that could likely engage students in understanding and transferring mathematical modelling to their living environments. The selected design-based research methodology and its characteristics, allowed to adapt task designs, settings and methods during my PhD research project. Hence, firstly, I investigated process skills learning (e.g.: mathematical modelling) with an automated tutoring system (the educational technology software MathemaTIC) within an international project. Although findings were promising, I redesigned my interventions to connect further students mathematical modelling learning to real-world information. Thus, secondly, I performed mathematical modelling tasks with augmented reality on real-world objects in remote teaching and in special needs educations. Utilising findings of these studies and a redesign of the intervention based on outdoor mathematical trails, thirdly, I undertook my final study. In pre-service teacher higher education, I explored outdoor mathematical modelling with an integrated STEAM (Science, technology, engineering, arts, and mathematics) approach. With the aim of such holistic approach, I collected data on education-related perceptions from different stakeholders of elementary school education (students, parents, in-service, and pre service teachers) and developed conceptual frameworks on task creation, mathematical modelling, and stakeholders' roles. In my PhD research project, I aspired to contribute and explain how in-class learning and teaching could be connected and transferred to mathematical modelling within students living environments. Although there are many crucial moments, method choices and findings within these studies, in this report, I will offer highlights of my PhD work and results. [less ▲]

Lorsque les pratiques multilingues en contexte professionnel international sont encadrées par des politiques linguistiques, elles donnent un point d’ancrage pour mesurer les oscillations entre le « prescrit » et l’«existant ». La caractérisation des pratiques multilingues d’une entreprise aéronautique européenne et de l’UNESCO demande de placer notre recherche à la croisée des champs de la linguistique, de la didactique des langues, de la sociologie, et de la psychologie sociale et cognitive. Nous allons présenter les résultats d’analyse des besoins déclarés par les salariés eux-mêmes, des interactions enregistrées en réunions et aussi des bilans d’entretiens. Ces deux terrains de recherche ont des caractéristiques linguistiques similaires : l’utilisation de l’anglais comme langue véhiculaire, la localisation d’un site à Hambourg en Allemagne, leurs sièges sociaux respectifs en France, des communications régulières avec des sites en zone hispanophone, ainsi que l’offre de cours d’anglais, de français, d’allemand et d’espagnol auprès de leurs employés. La polyphonie des discours sur les pratiques multilingues en entreprise montre les tensions existantes entre le choix de l’usage de l’anglais comme lingua franca et celui du français, de l’allemand et de l’espagnol qui ouvre différents « univers du discours » (Charolles 1997). A partir de la question de cadrage, envisagé au plan linguistique comme au plan sociologique, nous essayons d’établir le lien entre posture professionnelle et pratiques langagières. Il semblerait que les faits de pluri-compétences, de pluri-linguisme, de multi-linguisme et de pluri-activités donnent matière à repenser nos méthodologies d’enseignement des langues. Par ailleurs. La relation d’aide (Amério 1991, Lejot 2014) entre les employés favorise le développement des compétences linguistiques dans la langue cible. Notre objectif est ici de faire un lien entre les besoins linguistiques et culturels identifiés en milieu professionnel et le développement des compétences multilingues en milieu universitaire. La personne bilingue n’est pas une somme de deux personnes monolingues (Grosjean 1989), et au même titre, l’enseignement plurilingue n’est pas une somme d’enseignements monolingues au sein d’une même formation en langues appliquées. Des recherches en linguistiques comparatistes (Huemer, Lejot, Deroey 2019) et des méthodes pédagogiques basées sur l’autonomie de l’étudiant ouvrent des perspectives à explorer ou à approfondir.

The highly linguistically and culturally diverse reality of Luxembourg and its school system pose a great challenge to students, families, and teachers alike. This reality tends to produce one of the largest differences in reading performance between Luxembourgish and language minority children compared to other countries (PISA, 2019), which creates inequalities in students’ academic trajectory. Translanguaging as a pedagogy has been established to overcome these inequalities by disrupting language hierarchies and giving language minority children a space and voice to learn and prosper (García, 2019). To address the inequalities and help implement a translanguaging pedagogy in preschool, our project : (1) offered a professional development course in translanguaging to 40 teachers, (2) involves children’s parents to foster home-school collaboration through questionnaires and interviews, and (3) cultivates children’s linguistic, cognitive, and socio-emotional engagement in the classroom through linguistic tests and video observations. We also used focus groups and questionnaires at the beginning and the end of the course. The 18-hour course in Translanguaging (June to December 2019) aimed to challenge the teachers’ perception about multilingualism and equality in their classroom. Through the preliminary results of the focus groups, questionnaires and field notes, we were able to observe some positive changes in the teachers’ attitudes and beliefs about their language minority children such as realizing that language is a tool of communication. Teachers were also more positive about home-school collaboration. However, despite our continuous creative efforts, some teachers still maintained their traditional monolingual stance and conviction of parents’ lack of education and interest. Most of the teachers did, however, not completely overcome a monolingual bias and this remains our main focus in the remaining points and follow-ups of our project. References García, O. (2019).

Alors que l’an dernier étaient célébrés les 50 ans du réseau ARPANET et les 30 ans du World Wide Web, ces anniversaires étaient l’occasion de revenir largement sur les fondements du « réseau des réseaux ». Ce retour aux sources permettait de prendre la mesure des changements intervenus, mais aussi de continuités certaines, ainsi que de valeurs séminales qui sont régulièrement convoquées dans les débats contemporains. Cette intervention se propose de revisiter les héritages des débuts d’Internet et du Web en trois temps : celui de la mémoire, de la nostalgie et de la reconstruction d’un âge d’or d’abord. Ensuite nous aborderons les héritages et patrimoines matériels et immatériels de ces premières communications en réseaux, notamment le patrimoine nativement numérique (Born-Digital Heritage) que sont les archives du Web et les newsgroups de la communauté Usenet. Enfin nous nous intéresserons à la réactualisation récurrente de controverses nées dès les premiers âges du Web, voire en amont (en termes d’anonymisation, régulation, rôle des intermédiaires, neutralité, etc.).

In the past decade, we have witnessed a shift from technological determinism to more attention to the methodological and epistemological changes in historical research which the digital turn has brought about. This talk will focus on how the practice of doing history has changed in the digital age against the background of broader historical developments in the so-called digital humanities. I will argue that, in many ways, hybridity, seen at its most basic level as the integration of 'traditional' and 'digital' approaches, is the new normal for most historians. However, when more broadly conceptualised as the integration of newly emerging tools, technologies, materials, and/or practices in historical research, it also becomes clear that hybridity has a long and often unacknowledged history that predates the advent of computers – analog and digital. Against this backdrop, the first part of my talk traces this unacknowledged history and the debates accompanying the (wo)man-machine encounter in the historical research process more generally. As I will argue, this encounter needs to be qualified according to its most elementary phases (data & information gathering, processing, analysis, and dissemination). Crucially, the speed, enthusiasm, and rate of the uptake of new technologies differs, and has always differed, significantly across these phases. In the second half of the talk, I will then offer a concrete example of these insights by using my research on the diaries of Anne Frank as a case study and will demonstrate the hybrid nature of today's historical research process, both as a reality and potentiality. Exploring the longue durée of the impact of new technologies on the practice of history is not to deny the specificity of the current moment but helps us to see how 'digital' has now come to affect the entire historical profession in ways unseen before. Indeed, technology has become inescapable, even if many historians refuse to acknowledge the fact and remain reluctant to embrace it. Yet, we can only truly ground our current 'digital' practices, and learn from past experiences and expertise, by contextualising and qualifying what is new and what is not. The real challenge for our profession now is to take a mental leap forward and be consciously hybrid, to acknowledge that 'digital' is not merely complementary but integral to the practice of doing history, and purposely reflect its implications.

Numerous scholars advocate for translanguaging pedagogies to increase participation and learning opportunities for all students, in particular students with a migration background (Rosiers, Van Lancker, & Delarue, 2018). Conversely, critics argue that translanguaging can contribute to reiterate unequal participation dynamics and question the equitable access to curricular resources (Hamman, 2018). While most qualitative studies draw on observations of classroom practices of the teachers and/or the students, only few consider the students’ perspectives on these practices. The present paper aims to address this issue. While my doctoral project explores the translanguaging practices of four fourth-graders of different backgrounds and their development over time, this paper investigates their perspectives on translanguaging. From January to December 2018, I observed the students’ interactions with their peers and teachers in Years 4 and 5 and identified and recorded key events. Subsequently, selected events were shown to and discussed with the students. Findings based on recordings from discussions and stimulated recall interviews revealed, first, that translanguaging was the default mode of communication of all four students and was perceived as a common practice. Second, the newcomers reported that they translanguaged to communicate quicker and that translanguaging was particularly frequent in students who were not yet proficient language users. Similarly, students with more experience in the education system perceived translanguaging as an inferior practice and indicated using their home language as a scaffold with other students, but not with their teachers. The students’ self-monitoring connects to the classroom practices. [less ▲]

Point collocation is the oldest way to solve partial differential equations. Methods based on collocation have been studied since decades and many variations have been proposed over the years. More recently, those methods have shown a greater interest thanks to the advances in computing hardware. The collocation methods offer a great flexibility with regards to the discretization of a defined domain and the approximation of the field derivatives. This presentation will introduce the bases of the collocation methods and of the generalized finite difference method. The importance of the selection of the nodes involved in the approximation of the field derivatives will then be presented. Finally two aspects for which the method is particularly attractive will be detailed: the solution of a PDE from a given geometry with minimum discretization effort and the adaptivity of a model based on a posteriori error estimation.

A neoliberal and globally organized social work is the focus of this presentation, which discusses the very first results of an transnational research project on cross-border child protection and disability rights in the Greater Region including Belgium, Germany, France and Luxembourg (EUR&QUA) According to UN Conventions (UNCRC, 1990 and UNCRPD, 2006), States Parties shall ensure and promote the full realisation of all human rights and fundamental freedoms for all children and persons with disabilities. Essentially, the Conventions call upon States Parties to take legislative, administrative and other measures to implement the rights recognised in both Conventions. Such imperatives seem to contradict a neoliberal social policy, which is oriented towards restraint in market intervention, strict austerity and cost reduction, and individualisation of social problems (Cummins, 2018). Actually, initial research results suggest that cross-border social work care for children and their families is not always sufficient. Crossing the border often means breaking off helping relations in the home country and there is hardly any professional exchange between social work providers involved. As a result, a return to the original life context desired by the clients seems hardly feasible (EUR&QUA 2019). Furthermore, practitioners expressed concern that diagnoses and support needs were formulated with a targeted focus on care in a neighbouring country. The research also identified cases that were not in line with the Brussels-II-Treaty on cross-border custody procedures. Some results may be derived less from optimal child protection and disability rights than from neo-liberalism, managerialism and austerity. In order to counter this development, social work needs something like Machiavellian competences (Kusiak, 2018; Drouard, 2008), which consist of critically illuminating a dominant ideology, conducting empirical research and acquiring the corresponding strategic knowledge. To this end, the research project aims to establish a Master's programme to empower future social worker in cross-boarder protection tasks. [less ▲]

In her book “Arbitrary Rule. Slavery, Tyranny, and the Power of Life and Death”, the author Mary Nyquist describes the pairing of slavery and tyranny as "political slavery” and distinguishes it from the institution of slavery. She shows how the concept of political slavery has been used to describe political oppression since ancient times. Terms from the field of slavery were used by opposition groups to identify the tyrant. Nyquist also analyses the persistence of this concept and traces back its use in political philosophy and in literature from Greek and Roman antiquity to the early modern period. Political slavery became part of the tyrant topos. Authors from Late Antiquity give us many examples of how firmly images of slavery were rooted in the minds of contemporaries and how these images were incorporated into literary tradition and political discourse. Images from the world of slavery were applied in a wide variety of contexts, from criticism of an emperor's behavior or illustrating his loss of authority to characterizing the relationship between two emperors at a time when power was divided between pairs or quartets of emperors. The lecture will show how the presentation and perception of emperors of Late Antiquity, such as Diocletian and his co-emperors, were influenced by narratives from the world of slavery. [less ▲]

The present contribution seeks to advance psychological approaches in inclusion of persons with a disability or health condition in decent work. People with disabilities and mental ill health appear to be among the most neglected groups when it comes to integration into the labour market (ILO, 2018; WHO, 2011). Article 27 of the CRPD emphasises equal access to the labour market as a governmental obligation and obliges signatory states to take appropriate measures (CRPD, 2006). However, specific programmes and measures to promote the employment of people with disabilities based on a human image of "protean career attitude" (Fugate, Kinicki, & Ashforth, 2004) often achieve only moderate success despite the involvement of psychological services, as shown by the example of national concepts in Luxembourg (Limbach-Reich, 2019). Searching for reasons one can identify two main strands which, on the one hand, concern the perspective of people with disabilities in sheltered workshops with regard to the general labour market and, on the other hand, appear in the employers' insufficient recruitment practice (WHO, 2011). As the present study shows, for the majority of people in sheltered workshops this form of employment is the more attractive alternative under the given circumstances. Inclusion in the first labour market is only sought by a minority. The reasons given for the preference for a protected employment status are overstrain and negative experiences on the first labour market. At the same time, in an increasingly neo-liberal employment market, the willingness to employ people with disabilities seems to be only slightly pronounced. The majority of the population of disabled workers in a workshop are not considered attractive for the existing labour market, as they do not correspond to the propagated image of the individual oriented towards career advancement, entrepreneurship aspiration and self-optimisation (Seithe, 2013). In conclusion, it is demanded that psychology should review prevailing neoliberal assumptions about the human behaviour and become more politically involved. In particular, psychology has to ask itself whether, by pursuing inclusion in the labour market exclusively, it fails and contributes to blaming the victims, especially those with mental and psychological disabilities. If in the future there are fewer and fewer people available for paid work and unconditional basic income will rise (Harari, 2015; Kela, 2019), then psychology, in cooperation with other disciplines, must also face up to the challenges and develop approaches that make psychological well-being and self-actualisation possible beyond the overarching neoliberal employment rigor.

This paper deals with a question that is becoming increasingly important for historians who work with digitised cultural heritage: what are the politics of digitisation and what are its implications for historical research? Is the often-lauded democratising potential of digitisation also offset by risks, inherent in selection processes that might privilege the digitisation of heritage corresponding to existing national master narratives, the availability of funding and/or the priorities set by cultural policies and certain research agendas? How does transnational heritage fit into this picture when most digitisation projects are, in one way or another, nationally framed? What biases can digital archives introduce in our work and how does that differ from issues of bias and selection in the ‘paper’ archive? In discussing these questions, I will provide a couple of examples before emphasising the importance of more transparency in this regard and the need for guidelines about how digital archives are constituted. A key point to highlight is that professional historians can and should be more open to learn from the experience of digital archivists and librarians who are at the forefront of the digital turn in heritage work.

For almost all primes p of K, we consider the order of the cyclic group (G mod p), and ask whether this number lies in a given arithmetic progression.

In this work, we present our preliminary results on the 6-way coupling of 3 numerical solvers: XDEM for the Discrete Element Method (DEM), OpenFOAM for Computation Fluid Dynamics (CFD), and deal.II for Finite Element Method (FEM). We relied on the existing preCICE adapters for OpenFOAM and deal.II and we have implemented a new preCICE adapter for the eXtended Discrete Element Method (XDEM), an innovative DEM software developed at the University of Luxembourg. The XDEM adapter permits coupling of the particulate phase of DEM with CFD and FEM: - DEM+FEM is a surface coupling that performs the exchange of surface forces and displacement between the particles and a deformable solid; - DEM+CFD is a volume coupling that performs the exchange of porosity, momentum, drag force and buoyancy between the particles and the fluid. Put together with the pre-existing CFD+FEM coupling, we obtain a 6-way coupled multi-physics solver for particles, fluid and deformable solids. We have tested and evaluated our multi-physics solver on the tutorial case “Cylinder with a flap” derived from the benchmarking case of Turek and Hron, that we extended to include a particulate phase solved by XDEM.

The globalisation of the digital economy is indicative of a changing multidimensional paradigm driven by a number of factors: the primacy of intangible assets in value creation; a growing transnational and international dimension in the production and consumption of goods and services; the transition from human labour to artificial intelligence; the increasing dominance of networks of stakeholders over individual players; the emergence of new forms of sharing, creation, collaboration and innovation; and the need to harmonise rules, standards and policies (including in the area of taxation) within a multilateral framework. In a competitive geopolitical environment, the EU, characterised by disparities between its Member States and sometimes opposing national interests, is some way behind China and the uncontested leader of the digital pack, the United States. But Europe can carve out a place for itself alongside these digital giants, since it outperforms its competitors in some sectors of the DSM. These include the production of digital services (the main driver of digital globalisation) and the digital consumption of financial operations. [less ▲]

She joined the Christian Social People’s Party (CSV) and was elected to the Luxembourg Chamber of Deputies (1979-1989 and since 2018), where she particularly focused on social affairs and international relations, before becoming a Member of the European Parliament for three terms (1981-1999 and 2014-2018) and turning her attention to social affairs, employment and the working environment, as well as civil liberties.

Co-organization of the conference: This conference, organised by the Robert Schuman Initiative for European Affairs with the support of the C²DH, aims to examine the relationship between the Internet, EU regulation and market integration from a historical perspective. The speakers will analyse how the development of the Internet has facilitated market integration while also creating major regulatory challenges at the EU level, e.g. peering between ISPs, the taxation of electronic commerce, data protection issues, etc. We are also honoured to welcome Dr Viviane Reding, who will speak about her action as European Commissioner for Information Society and Media (2004-2010). Speakers: Elena Danescu (C²DH, University of Luxembourg), Stefan Gadringer (University of Salzburg), Christian Henrich-Franke (University of Siegen), and Dr Viviane Reding, Member of the Chamber of Deputies of Luxembourg (since 2018) and Member of the European Commission (1999-2014) – the first European Commissioner with responsibility for the Information Society and Media. Moderation by Frédéric Allemand, Andreas Fickers, David Howarth and Valérie Schafer (University of Luxembourg). [less ▲]

Si les historien-ne-s se sont d’abord intéressé-es à l’histoire d’Internet avant celle du World Wide Web, la recherche dédiée au Web s’est développée ces dernières années, en lien avec un intérêt croissant pour les usages et les cultures numériques. Les archives du Web ont également contribué à stimuler l’intérêt pour la Toile et cette intervention se propose de revenir sur ces jalons historiographiques récents et majeurs. Aussi nous interrogerons en trois temps les territoires balisés, mais aussi les opportunités qui s’ouvrent pour l’histoire du Web : après avoir considéré les recherches liées aux « temps pionniers » et au World Wide Web en tant qu’innovation socio-technique, seront abordés les travaux portant sur le « Web en contexte » (et notamment à l’échelle nationale). Enfin, le « Web en société » et ses cultures numériques sont également devenus un terrain d’étude fécond, pour lequel nous développerons également quelques exemples et pistes de recherche. Ces trois axes invitent à penser l’écriture d’une histoire qui nous parle autant du Web du passé que du présent de la recherche. [less ▲]

Placing the design and use of computing devices into a broader context, I focus on the societal, business, and labour developments at the basis of new computer models. One of five carefully selected case studies considers the use of Powers-Samas and later I.C.T. punched card equipment in accounting at the Helena Rubinstein make-up concern in London during the 1950s. For each case my research looks into changes in occupations after the introduction of new computer models, as well as its influence on the work space and workflow of employees. Finally, I study gender stereotypes in advertisements of the computers, and in this case of the punched card equipment. During the Work in Progress session I will briefly introduce my overall research approach and demonstrate which sources are available, and what is still missing for the punched card equipment case study.
