In recent years, scholars have started to investigate the diverse genealogies of the digital humanities, as part of efforts to consolidate the field by excavating its historical and intellectual underpinnings. This paper discusses the history of what we now call digital history, by focusing on its direct predecessor: the history and computing movement. It argues that understanding the current era of digital history is impossible without knowledge of the transnational history & computing movement out of which it emerged. The paper will first offer a conceptual framework for the nexus between technology and historical research practices and provide a brief outline of the uptake of computing in historical research in the post-WWII period, which was rooted in a broader context of engagement with reproduction and data processing technology that began in the late 19th century. From the 1940s onwards, historians begin to use analog and later digital computing, efforts that truly gained momentum from the early 1960s onwards in the United States, Western Europe and the Eastern bloc led by the Soviet Union, against the backdrop of the Cold War and a general surge in the use of computing in various humanities disciplines. By the late 1960s we begin to see the establishment of networks and structures to support what could be called an emerging transnational field of computing historians. A transition to a new phase began when first micro- and then personal computing were introduced at universities in the early 1980s and a new user generation of computing historians emerged. As had happened almost two decades earlier, a transnational network would develop, but this time formalised in the Association for History and Computing (AHC) which existed until the early 2000s. The AHC’s history, activities, and many publications highlight the transnational outlook and intellectual breadth of the history and computing period and can served to probe the transition to and (dis)continuities with our current era of digital history. As I will argue, the history and computing movement did not simply give rise to digital history around the turn of the millennium. Despite the continued involvement of some older practitioners, many of the new digital historians were, as before, of a different user generation and the transition to digital history was thus much more than discursive.

Seit einigen Jahren hat die ostbelgische Regionalgeschichtsschreibung versucht, den von Philipp Ther geprägten Begriff des ‚Zwischenraums‘ für die Historiografie über diese belgisch-deutsche Grenzregion im 19. und 20. Jahrhundert fruchtbar zu machen. Diese konzeptionellen Überlegungen fanden ihren Niederschlag zunächst in der Buchreihe „Grenzerfahrungen. Eine Geschichte der Deutschsprachigen Gemeinschaft Belgiens“ und dann vor allem in der am C²DH entwickelten virtuellen Ausstellung www.zeitschichten.be (2020). Der erste Teil des Vortrags besteht aus einer Meta-Führung durch die zum 100. Jahrestag der Zugehörigkeit der Region zu Belgien entwickelte Online-Expo. In einem zweiten Schritt sollen auf der Grundlage einiger der darin genutzten Quellen Überlegungen dazu angestellt werden, ob sich die Geschichte Ostbelgiens auch als die eines popkulturellen Zwischenraums deuten lässt. Dabei standen der faktischen Hybridität der regionalen, ländlich geprägten Kultur oftmals von der Sehnsucht nach nationaler Eindeutigkeit geprägte Selbstzuschreibungen entgegen, die die Suche nach dem Platz der Ostbelgier in Belgien, zwischen Belgien und Deutschland und zwischen zwei großen westeuropäischen Sprachräumen widerspiegeln.

The popularization of large-scale federated Genome-Wide Association Study (GWAS) where multiple data owners share their genome data to conduct federated analytics uncovers new privacy issues that have remained unnoticed or not given proper attention. Indeed, as soon as a diverse type of interested parties (e.g., private or public biocenters and governmental institutions from around the globe) and individuals from heterogeneous populations are participating in cooperative studies, interdependent and multi-party privacy appear as crucial issues that are currently not adequately assessed. In fact, in federated GWAS environments, the privacy of individuals and parties does not depend solely on their own behavior anymore but also on others, because a collaborative environment opens new credible adversary models. For instance, one might want to tailor the privacy guarantees to withstand the presence of potentially colluding federation members aiming to violate other members' data privacy and the privacy deterioration that might occur in the presence of interdependent genomic data (e.g., due to the presence of relatives in studies or the perpetuation of previous genomic privacy leaks in future studies). In this work, we catalog and discuss the features, unsolved problems, and challenges to tackle toward truly end-to-end private and practical federated GWAS. [less ▲]

Modern cities all over the world are now more susceptible to flash floods as a result of a rise in the frequency and severity of meteorological events with significant precipitation. For minimizing the risks due to these hydro-meteorological hazards, reliable fore- and now-casting of severe precipitation has become essential. Water vapor can be measured along slant paths by network of ground-based GNSS stations, providing real-time, three-dimensional (3D) distributions of vapor concentrations at an affordable cost. Consequently, these data provide an invaluable additional source of knowledge for monitoring and predicting events with flash flood potential. But site-specific multipath (MP) effects at GNSS stations do affect incoming signals, particularly at low elevations, as is widely known. The bulk of GNSS products for meteorology up to now are based on estimates of ordinary zenith total delay and horizontal gradients with little sensitivity to azimuthal variations, thus these products may not be best suited for estimating 3D distributions of water vapor during storm events. Using slant delays directly, can overcome this lack of azimuthal information. However, at low elevations, this approach is more susceptible to multipath errors. A thunderstorm event which occurred over Turkey and adjacent countries on July 27, 2017, resulting in flash floods and severe infrastructure damage, is used as an example to explore the effects of multipath-corrected slant wet delay (SWD) estimations on monitoring extreme weather events. To reconstruct the one-way SWD, we first added phase residuals derived from the GNSS one-way post-fit observations, which represent the anisotropic component of the SWD. This can also be interpreted as a higher order inhomogeneity component, which is not resolved by ordinary zenith or gradient products. For the generation of site-specific MP correction maps, we stacked the post-fit residuals derived from our Precise Point Positioning (PPP) processing strategy because the MP errors in the GNSS phase observables can adversely impact the SWD along the direction of individual satellites. The spatial stacking was performed in congruent cells as a function of elevation and azimuth. This enables each cell to receive roughly the same number of residuals, providing a better stacking result. The stacking of residuals for a single cell over several days allows the detection and reduction of systematic errors; random errors are minimal because the averaging is done over a suitably sufficient chosen time span. Finally, the one-way SWD were enhanced by applying these MP correction maps for the analysis of the meteorological event. Our study revealed that the anisotropic component contributed up to 11% of one-way SWD estimates. Furthermore, the spatio-temporal changes in SWD as derived from GNSS closely matched the moisture field from the ERA5 re-analysis linked to this weather event. As it turns out, the MP correction maps may also provide a “kind of calibration” for uncalibrated or low-cost GNSS antennas, even for those in mobile phones, as these devices are highly susceptible to MP errors. In turn, this would allow the application of low-cost sensors to accurately estimate SWD for severe weather monitoring in urban regions. [less ▲]

To effectively cope with the intermittency of VRE, power systems will need different flexibility options. The future portfolio of flexibility options will differ among countries, as it will be determined by the political, economic, social, technological, legal, and environmental factors of a country. Thus, some countries might have a greater need for flexibility options than others. Generation and expansion planning for renewable power systems on a national level are complex and require large long-term investments. Therefore, it is crucial to estimate the "need for flexibility" in energy systems from a macro-level. By assessing relevant indicators (e.g., economic) and different boundary conditions (e.g., VRE capacity), power system planners, policymakers, operators, and regulators can evaluate the need for flexibility in power systems and prioritize the needed actions. Published research and international reports do not refer to the countries with the highest need for flexibility options in respective power systems. In this regard, the aim of this paper is to answer the following question: "Which countries in the world have the highest need for flexibility options from a macro-energy systems point of view?" To answer our question, first, we have identified relevant indicators from the literature that can help us to estimate the "need for flexibility" in national power systems. Second, we weighed the different indicators according to their importance by using the analytical hierarchy process (AHP) of the multi- criteria decision analysis (MCDA) process. Finally, this paper proposes a “global index for flexibility need” using these indicators. As for the results, countries were ranked in this index based on indicators and already show us the promising countries with the top 10 dominated by European countries. This index works as a macro-level assessment framework that provides the comparative position of countries with regard to the need for flexibility. This index will help technology providers and increase investor confidence to choose countries with the highest "flexibility need" for technology implementation. This will help relevant stakeholders to focus on key countries first to accelerate the integration of VRE and thus help the global energy transition. [less ▲]

On 24 February 2022, the armed forces of the Russian Federation launched an unprovoked full-scale invasion of Ukraine. This was an unprecedented act of aggression against a sovereign and independent country and goes against fundamental principles of international law. It has been strongly condemned by the international community, including the European Union. As of mid-May, over six million Ukrainian and international refugees are fleeing the war to neighbouring EU and third countries (including Moldova) and eight million people have been displaced internally. This massive inflow of Ukrainian refugees into the EU resulted in the Council adopting the implementing Decision 2022/382 of 4 March 2022, introducing temporary protection as a means of dealing with the crisis. This is the first time, that the Temporary Protection Directive has been triggered in the Member States. The EMN has collected information in relation to the Temporary Protection Directive implementation in Member States (e.g. registration) and how the rights conferred to the Beneficiaries of Temporary Protection are provided (e.g. accommodation, healthcare, education, social welfare, etc.) The objective of this workshop is to increase participants’ knowledge in handling information related to the implementation of TPD. The target audience are EMN Member States and the EMN Service Provider but participation is also open to Commission policy officers, EU MS officials and EU agencies. [less ▲]

Project WARLUX - Soldiers and their Communities in WWII: The Impact and Legacy of War Experiences in Luxembourg", at the Luxembourg Centre for Digital and Contemporary History (C²DH) of the University of Luxembourg researches the personal side of the history of Luxembourgish youth born between 1920 and 1927 who were enrolled into German services under the Nazi occupation of Luxembourg during World War II. The research focuses on personal testimonies and their individual war experience to uncover these men, women, and families' individual experiences. The Methodology includes a biographical approach to offer a micro-historical perspective on single actors to link individual life stories to home communities. WARLUX will analyse the individuals from their social environments, social background, or trajectories during the war and their life in the post-war period based on their biographies. But this is almost where the most significant challenge lies in avoiding pre-existing terminologies, e.g. Nazi terms. When analysing the dataset of contemporary Nazi documents and post-war documents, the sources describe the same objects and elements but require a different interpretation. When building a dataset for independent and objective research, it is crucial to distinguish between the various sources and make the data entries comprehensible. While for the Nazis, volunteers in the Waffen-SS were "exemplary fighters", in post-war Luxembourg, they were "traitors to the fatherland". The young men who deserted from the Wehrmacht during the war, "cowards" and "Wehrkraftzersetzer" for the Nazis, in peacetime "heroes" of the Grand Duchy of Luxembourg. The project has worked with a relational database (nodegoat) so far but is reaching its limits. This database's strength lies in linking objects while assigning strict categories and dates but fails when it comes to flexible and uncertain or ambiguous data. In many sources, there are different variations of dates and circumstances of the targets under study. For example, the Nazi authorities introduced the conscription law in Luxembourg on 30 August 1942. Every man born between 1920 and 1927 was called to register on the conscription lists. Therefore, men who enlisted in the Wehrmacht before this date are considered volunteers, which completely changed their status as mentioned during the war and after returning home. Mapping this scheme in a data model seems "easy" - date of enlistment XX, and then building the category of volunteer yes/no. But as the data repeatedly shows, it is more complex than expected. Volunteers who joined the German forces before August 1942 tried to avoid their "real" enlistment and changed it to an earlier date (reporting to the authorities) because they were aware of the severe consequences they and their families faced after the surrender of the Nazi forces. There are now two dates in the dataset. The relational structure only allows one date for the volunteer "tab". If I had chosen only one date, this case would have been overlooked. The analysis requires a flexible and changeable dataset where the fixed points can be changed depending on the research question. It is always a challenge in historical research. Still, due to the mass data (10,000 objects/persons) that WARLUX uses, it needs a flexible and smooth data structure and, on the other hand, one that is as stringent and reliable as possible.

After the Second World War, in line with its new strategic choice Luxembourg resolutely set out on the road to international multilateralism and European integration, being in 1951 one of the six founding members of the European Coal and Steel Community (ECSC), and in 1952 - the workplace of the newly established European Community institutions. Since then, Luxembourg has played and continues to act as a mediator and a force for ideas in the EU, either as a member State, or through some of its leaders (including Joseph Bech, Pierre Werner, Gaston Thorn, Jacques Santer, Jean-Claude Juncker). Based on a wide range of sources from public and private archives, this presentation aims to illustrate how the Grand-Duchy had become a master of small states diplomacy and a consensus builder in the European integration history, and to demonstrate that the influential nature if its leadership gave Luxembourg a role that far outweighed the country’s socio-economic impact.

Beginning in the 20th century, Luxembourg experienced several periods of transition. The largely agriculture-based economy became industrialized, driven by a powerful steel industry which remained the dominant sector from the immediate post-Second World War years to the mid-1970s. In 1974 the steel industry began to decline, marking the end of the ‘Trente Glorieuses’. Luxembourg was forced to implement considerable structural changes and embarked on its second major transition, from an industrial economy to a service economy based on the financial sector. To guarantee its future position in a competitive globalized environment, the country needed to diversify its economy by focusing on state-of-the-art fields with high added value, while preserving the competitiveness of the financial sector. Luxembourg continued to prioritize innovation as the main driver of sustainable and inclusive growth, embarking on its digital transition in order to build a "smart nation". [less ▲]

Council Regulation No 1024/2013 (‘SSM Regulation’ or ‘SSMR’) confers exclusive competence on the ECB to carry out specific supervisory tasks with regard to credit institutions established in the Euro Area Member States. When the ECB carries out its supervisory tasks, it is “considered, as appropriate, the competent authority or the designated authority in the participating Member States as established by the relevant Union law”. Any reference made in the CRD IV to a National competent authority (NCA) shall thus be read as a reference to the ECB whenever the ECB is competent. However, this does not turn the ECB into a super NCA. Although the SSMR has granted the ECB most of the powers necessary to carry out its new tasks, the ECB lacks certain specific powers that national laws have given to national supervisors. Filling this gap and ensuring a high level of consistency in the exercise of prudential supervision require the definition of complex administrative composite procedures where the identification of responsibility and accountability of the ECB and the NCAs is particularly blurred. Ten years after the creation of the SSM, it will be time to consider a number of developments in the legal framework, as this contribution will discuss in conclusion. [less ▲]

The purpose of our Hivi research project (https://hivi.uni.lu) is to historicise and to contextualise online virality through the different ages of the Web. This allows to grasp the evolution of digital cultures, as well as the changes of platforms, audience, formats, and the cross-platform, transnational and transmedia circulations of Internet phenomena (memes, online challenges, etc.). There are also continuities of practices to be retrieved, such as trolling, participation and remix. Even in the short time of the history of the Web, viral phenomena have undergone rapid and constant changes, due to the evolution of the Web (appearance or disappearance of platforms and web sites, changes of interfaces, etc.), of digital practices (may it be related to content production or consumption), and of the phenomena themselves, which are flexible, adaptable and versatile. To reflect on the temporalities and spatialities of these ephemeral and changing phenomena, this talk will present the sources and tools we are currently using, the methodological challenges we are also facing while exploring a large amount of data and sources (may it be on the living or archived web).

From the Hampster Dance, All your Base are belong to us and the Dancing Baby in the second half of the 1990s to Bernie’s mittens at the US presidential inauguration and the image macros of the Evergreen blocked in the Suez Canal, through Disaster Girl or Distracted Boyfriend to name but a few, memes and Internet phenomena have become in the last twenty years an important part of our digital cultures (Shifman, 2014). After presenting why historicising virality matters (which is the purpose of our Hivi research project supported by the Luxembourg National Research Fund and conducted at the University of Luxembourg, https://hivi.uni.lu), this talk will focus on the challenges related to sources. Historicising online virality requires to first acknowledge how difficult it is to build corpora and develop chronological views in the vast and heterogeneous amount of data lakes and sources available on the live web and in web archives. All these repositories preserve viral content in a very different manner, covering different frames and periods, while the actors who come into play have different size and motivations, from giant platforms (Twitter, YouTube - see Burgess and Green 2018, etc.) to small communities, through heritagisation platform (i.e. Know Your Meme - see Pettis, 2021) and web archives. Therefore, it is necessary to consider the many levels of politics, curation and agencies at stake when studying the history and heritagisation of memes and Internet phenomena and their impact. Finally, temporalities and scales are also challenging, and scalability is key for studying the spreadability of digital contents, notably in a long-term perspective. There is a constant need for balancing between several scales to study circulation and flow (Jenkins, 2009), processes, participation (Milner, 2018) and appropriation, while recontextualizing memes and Internet phenomena in their complex and changing environments (changes of platforms, of participation, of audience, of meaning...).

In political terms, European integration and multilateral cooperation enabled Luxembourg to become an equal partner in the decision-making processes and leadership of European organizations. In economic terms, these features gave the country the tools it needed to forge a development model that could underpin the creative growth of its social market economy, while preserving the majority of its vital interests—particularly the steel industry and the financial centre—over the long term. Focusing primarily on the 1970 Werner Report, which served as a blueprint for the European single currency - the euro - the presentation examines a key period in European integration history and one of the major European achievements of Luxembourg and of Pierre Werner (29 December 1913– 24 June 2002), former Prime Minister, Finance Minister and Foreign Minister of Luxembourg, who left his mark on the future of his country and is unanimously recognised as one of the architects of Economic and Monetary Union.

The associated constitutive relation is consequently using principal quantities and captured by the parameter-free representation using a deep neural network. The presentation investigates certain physics-motivated requirements imposed on the architecture of the artificial neural network such as symmetry and objectivity criteria. The training phase of the constitutive ANN operator employs a loss function which ensures the identified consistency conditions. The prediction phase exploits a constitutive blending approach to stabilise the numerical solution procedure in the presence of typically local stretch/stress extrema. The presented approach is implemented using FEniCS and builds on symbolic representation of the ANN operator based on the Unified Form Language (UFL). The neural network is constructed, trained, and tested using PyTorch. Numerical benchmarks demonstrate the ability of the presented formalism to describe non-trivial load-deformation trajectories of 3D test specimens. [less ▲]

As famous as the quotation by Lawrence Lessing “Code is law”, the sentence by David Clark at a meeting at the IETF in 1992 “We reject kings, presidents and voting, we believe in rough consensus and running code” became a “motto for Internet standardization” (Russell, 2006) that invites us to have a look at the past relationships and intertwinements between networks design and governance. From the 1970s topics related to distribution and openness have become key in networks infrastructures, while complementary issues related to asymmetries and multi-stakeholderism (Raymond and DeNardis 2015) have been emphasized in the 1990s and 2000s, and notably during the WSIS in Tunis and Geneva. Research related to Internet governance (Mueller and Badiei, 2020; Musiani, Schafer, 2021) has also brought to the table strong issues related to agencies, privacy, and many others that have strongly followed the development of networks and their uses as well as controversies related to net neutrality or information flows for example (DeNardis, 2020). This presentation will go through several historical case studies and rethink them through the lens of infrastructure design and governance, from Arpanet in the 1970s, XNS and then the OSI (Russell, 2014), to web archives (Schafer, Winters 2021) and research infrastructures today, through past designs and attempts, related to the Web and Xanadu, the Minitel (Schafer, Thierry, 2012; Mailland, Driscoll, 2017), platforms like Wuala (Musiani, 2022) and Wikipedia (Cardon and Levrel, 2009). This will allow us to explore some notions and approach related to closure, secret, incentives, empowerment, while finally moving from “governance” to “good governance” and its challenges. [less ▲]

Les phénomènes viraux et en particulier les gifs et les mèmes ont donné lieu à des études (par H. Jenkins, L. Shifman, R. Milner, D. Kaplan et N. Nova, J. Eppink, A. Wagener et bien d’autres) qui éclairent les phénomènes de circulation, participation, partage (cf. également les recherches de N. John) et transformation au sein des cultures numériques. Les phénomènes viraux sont bien sûr présents dès les débuts du Web et certains voient dans les émoticones ou la loi de Godwin leurs premières occurrences (J. McGrath). La fin des années 1990 marque par ailleurs le succès du Dancing Baby, de la Hampster Dance ou de All Your Base Are Belong To Us. Les réseaux socio-numériques ont accéléré ces circulations, par ailleurs transplateformes, tout en mettant au défi le chercheur qui souhaite appréhender et historiciser la viralité. C’est notamment l’ambition du projet HIVI (A history of Online Virality) à l’université du Luxembourg (2021-2024). Sans surprise un premier défi est celui des archives et de la constitution de corpus. La présentation les abordera autour de trois axes: tout d’abord le défi de la masse et de l’hétérogénéité des sources, de leur périmètre, mais aussi l’inégale préservation des phénomènes Internet, ainsi que la pluralité des espaces de patrimonialisation et modes de curation seront présentés; ensuite nous nous intéresserons plus particulièrement aux sources nativement numériques conservées dans les archives du Web, et leurs défis en termes de préservation, recherchabilité, contextualisation. Enfin des enjeux méthodologiques, notamment liés aux temporalités et spatialités seront soulevés, pour engager la discussion sur les apports mais aussi les limites des sources nativement numériques.

The Werner Committee's work was characterised by political and doctrinal differences between “economists” (the countries with weak currencies – France, Belgium and, to a certain extent, Italy) and “monetarists” (the countries with strong currencies – Germany and the Netherlands)– namely, those who saw monetary integration as a means of economic integration and those for whom it was the ultimate goal. The conflict was ultimately resolved by the adoption of a parallel approach between economic cooperation and monetary coordination in the Member States, a principle of equilibrium on the basis of which Pierre Werner was able to secure a consensus. This paper makes extensive use of Pierre Werner’s previously unpublished archives and a collection of original oral history accounts with key players of European monetary integration. An interdisciplinary approach, together with digital methodologies (network analysis and the TXM corpus analysis framework), will be used to explore the negotiations within the Werner Committee by examining the dynamics between group members, their emerging views on EMU, their political commitment to a European currency, the similarities and differences between their ideas, their personal networks, the influence of their respective countries, their theoretical and methodological input and their contribution to the political agreement.

Der historische Atlas der Stadt Luxemburg wurde im Unterschied zu bisher veröffentlichten Atlanten anderer Städte allein für eine Veröffentlichung im Internet konzipiert. Seit 2019 ist er im Internet auf der Seite luxatlas.lu zugänglich und wurde seither kontinuierlich ausgebaut, überarbeitet und verbessert, sowohl technisch als auch inhaltlich. Aktuell bietet sich Nutzern die Möglichkeit, eine Vielzahl historischer Altkarten und Luftbilder der Stadt Luxemburg aus dem Zeitraum zwischen 1560 und 2017 in beliebig wählbaren Zoomstufen zu betrachten und auf transparenten Ebenen passgenau übereinanderliegend miteinander zu vergleichen. Ergänzend lassen sich historische Fotos und Ansichten sowie erläuternde Texte zur Stadtgeschichte und zu ausgewählten Gebäuden oder anderen Infrastrukturelementen einblenden. Der Luxatlas dokumentiert historische Veränderungsprozesse diachron für Forschungszwecke. Dabei steht die reine Visualisierung von Forschungsergebnissen aber nicht im Vordergrund. Vielmehr dient der Atlas selbst als Instrument zur Gewinnung neuen Wissens. Erst durch die Überlagerung verschiedener kartographischer Zeitschichten und die Verknüpfung von historischen, architektonischen, demografischen, wirtschaftlichen und städtebaulichen Informationen wird die Verteilung bestimmter räumlicher Phänomene sichtbar und kann von Nutzern interpretiert und analysiert werden. Auf diese Weise wird die interaktive Karte zu einem zentralen Instrument des Wissenserwerbs. Um die Vorteile einer Webpublikation bestmöglich umzusetzen, basiert der Luxatlas auf Open-Source-Software. Dies ermöglicht die Entwicklung maßgeschneiderter WebGIS-Anwendungen für die spezifischen Anforderungen des Projektes. Der Vortag wird neben der Projektvorstellung auch die methodischen und quellenkritischen Herausforderungen beleuchten und den geplanten weiteren Ausbau zur Diskussion stellen. [less ▲]

Die Studiengänge an der Universität Luxemburg sind überwiegend mehrsprachig. Vor diesem Hintergrund sind die mehrsprachigen Kompetenzen unserer studentischen Hilfskräfte im Sprachenzentrum von zentraler Bedeutung. In diesem Zusammenhang werden den Studierenden Peer-Tutoring- und Tandemprogramme angeboten, um sie bei ihrem Integrationsprozess in unser Universitätssystem zu unterstützen. Wir haben im Rahmen eines gemeinsamen Kurses der sechs Sprachzentren der Grenzuniversitäten, der Studierende sprachlich und kulturell auf eine zukünftige Mobilität vorbereiten, ein Tandemmodul integriert, das diese Studierenden zur gegenseitigen Hilfe unter Gleichaltrigen anregen soll. Wenn sich Tandems ergeben sollten, schulen wir unsere studentischen Hilfskräfte darin, Gruppen bei der Durchführung von Tandem-Aktivitäten zu begleiten. Die Studierenden müssen sich auf drei bzw. vier Aktivitäten einigen, die sie gemeinsam durchführen. Um den Nutzen dieser Partnerschaft zwischen Studierenden und studentischen Hilfskräften zu maximieren, werden wir in dieser Mitteilung über die Entwicklung einer Vorgehensweise und eine Verstärkung der Begleitinstrumente nachdenken, die darauf abzielen, ihre "Tandem-Sitzungen" in Gruppen zu strukturieren.

Carbonopolis: Letz bring it down! is a prototype board game that stimulates awareness and encourages exchange on six climate change topics impacting Luxembourg: urban heat islands, extreme weather, quality of life, mobility, housing and the food system. Whilst playing, participants discover and discuss potential sustainable planning initiatives for carbon descent. Aimed at groups of multicultural players, the game was inspired by snakes and ladders and integrates three type of playing cards: (1) multiple-choice questions for knowledge testing (2) planning initiative cards for value-driven policy prioritisation and (3) crisis cards for critically reflecting on current policy impacts. The initial game design was conceived by two academics. Then in the spirit of co-design, as a sustainability action for all, and with the goal of building partnerships beyond the formal curriculum we integrated three Master student assistants and one doctoral student into the process, especially in the graphic design and game evaluation. During play sessions students assumed different roles: players, game leaders and game observers. The game provided an opportunity to raise awareness of local sustainability challenges and nurture future advocates. Additionally, the process provided an interactive and playful method for new co-productive curriculum development and the development of team-based relationships between staff and students. [less ▲]

The lecture by Inna Ganschow in the framework of LuxTime Machine is about two years in the history of the Minette region, from 1942 to 1944. The reconstruction focuses on the life in the camp of the female forced labourers who had been deported from the Soviet Union for slave labor in the steel industry of Luxembourg. "The big data of the past" as much as the so called ego-docments like letters, photos and memories after the liberation allow to get to the bottom of the daily life of thousands of the Soviet teenagers, who lived directly at the plant in the barracks behind the barbed wire, were subjected to an enormous workload and had neither enough food nor free time.

The multitude of chemicals to which we are exposed is ever increasing, with over 110 million chemicals in the largest open chemical databases, over 350,000 in global use inventories, and over 70,000 estimated to be in household use alone. Detectable molecules in exposomics can be captured using non-target high resolution mass spectrometry (HRMS), but despite the size of the chemical space, scientists cannot yet identify most of the tens of thousands of features in each sample, leading to critical bottlenecks in identification and data interpretation. This talk will cover European and worldwide community initiatives and resources to help connect environmental expert knowledge and observations towards a better understanding of the exposome, including various open cheminformatics and computational mass spectrometry approaches such as the NORMAN Suspect List Exchange, MassBank, MetFrag and PubChemLite for Exposomics.
