[more ▼] 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.

[more ▼] Every culture chooses its own approach and creates its own authority to provide answers to the uncertainties of human life in socety. Since God has become obsolete as the guarantor of our society, it is up to instances such as the State, the People or the Market and the corresponding institutions to act in a way that creates meaning and reduces uncertainty. In the face of worsening crises (climate, wars, representation...), however, these instances are also increasingly losing their binding power, effectiveness and legitimacy. Increasingly, therefore, the focus lies on algorithmic-based technologies, which, due to their number-based approach, are seen as the more reliable supplier of answers to the most pressing questions of our time. Unlike in the case of the previously mentioned instances, here, at least it seems, belief in the validity of their statements is no longer necessary: rather, by resorting to ever more extensive amounts of data, social and individual life is calculated, predictable and correspondingly controllable. Moreover, in the same way - in the sense of technological solutionism - it should be possible to defuse the most pressing crises.Two technologies in particular come to the fore: With blockchain technology, the last factor of uncertainty - the middleman legitimising transactions - is now eliminated: Via algorithmically controlled consensus and automation processes, the decentralised, transparent and unforgeable control and regulation of binary and social processes will become possible and a "more reliable truth than any truth we have ever seen" (Casey/Vigna) will be created. With (General) Artificial Intelligence, an entity is supposed to emerge that, on the basis of extensive data and self-learning algorithms, can replace the human, i.e. fallible intellect, and - eradicating any uncertainties - calculate and answer the unanswerable questions of human life. Against the backdrop of the recent French history of ideas, I will explore in my paper to what extent this is actually a new - safer - form of uncertainty reduction or not; in other words, I will pose the question to what extent blockchains and AI actually eliminate uncertainties or exacerbate existing uncertainties or create entirely new uncertainties.

[more ▼] Dekorporalisierung = Demokratisierung? Öffentliche Meinung im Sog der Virtualisierung Gegenwärtig erleben wir das Aufkommen neuer Technologien, die über den Weg der Dezentralisierung versprechen, gesellschaftlichen Kontexten eine demokratischere Ausrichtung zu verleihen und so der Vassalisierung durch korrupte Institutionen und daten- und clickbait-hungrige Medien-Plattformen etwas entgegenzusetzen: Im virtuellen, dezentral strukturieren Raum soll es möglich werden, individuelle wie gesellschaftliche Angelegenheiten freiheitlicher, offener und demokratischer zu gestalten. Hier ist die Rede von „Netzwerkstaaten“ oder „Cloud Communities“. Neben dem Problem der unweigerlich stattfindenden – und das Demokratische dieser Organisationsformen in Frage stellenden – Homogenisierung stellen sich darüber hinaus Fragen zur Möglichkeit von Öffentlichkeit, Meinung und Politik im anonymisierten und dekorporalisierten Raum: Kann mit Blick auf die Grenzenlosigkeit der Virtualität überhaupt von einem „öffentlichen Raum“ die Rede sein? Und impliziert die Entkörperlichung des Politischen, d.h. seine Loslösung vom geographischen Raum, aber auch vom Körper des Meinungsurhebers wie -trägers wirklich mehr Freiheit und Demokratie? Und welche Auswirkungen hat das für die bei allen Virtualisierungsbestrebungen fortbestehende Öffentlichkeit im traditionellen Staat? Diesen Fragen wird mein Vortrag nachgehen und dabei zudem die Problematik der Urheberlosigkeit von durch KI-Anwendungen wie ChatGPT entstehenden meinungsbildenden wie -vertretenden Texten in den Blick nehmen.

[more ▼] In 2017, the new law declared multilingual education mandatory in Luxembourg where there are 65% of 4-year-old language minority children. To support 40 teachers with the new law requirement that asked teachers to use children’s home languages in the classroom, we offered a 6-month professional development course in translanguaging pedagogy that builds on children’s full linguistic repertoire. Mixed methods were used such as focus groups, questionnaires, and video observations. Through pre- and post-course focus groups we identified three groups of teachers: (1) those with mild monolingual stance who believed that the most important is to develop children’s school language, Luxembourgish, (2) those with mild translanguaging stance who expressed that children’s home languages are important but can hinder children’s Luxembourgish, and (3) those with true translanguaging stance who believed that children’s home languages are necessary for their well-being and development of Luxembourgish. The questionnaires showed that there was a significant increase in teachers’ positive attitudes towards children’s home languages and translanguaging. However, in the video observations we identified both positive and negative examples in teacher-designed activities that, when compared to the focus groups and questionnaires results, seemed paradoxical but portrayed a fuller picture of preschool teachers’ translanguaging stance in Luxembourg.

[more ▼] We study a dynamic principal-agent model in which the principal is a group whose members hold heterogeneous and evolving values from an agreement with the agent. The principals collectively choose the agent’s offer, which binds all principals if the agent accepts. Learning about the agent’s private information reduces the principals’ conflicts over their joint offer, mitigating a principal’s subsequent losses if she is not decisive. As a consequence, a principal in a group prefers to screen the agent more aggressively than a single principal. We study the dynamics of the principals’ collective choice, and obtain conditions under which decisive members of the group successively trade away their decision-making authority, leading inexorably to the concentration of negotiation power in the hands of a single principal.

[more ▼] Craters are distinctive features on the surfaces of most terrestrial planets such as Mars and Venus. The distribution of craters reveals the relative ages of surface units and provides information on surface geology. Extracting craters is one of the fundamental tasks in planetary research. Although many automated crater detection algorithms have been developed to extract craters from image or topographic data, most of them are applicable only in particular regions, and only a few can be widely used, especially in complex surface settings. On the other side, once we have a reasonable craters data, statistics play an important role in better understanding their features, in particular their distribution. In this workshop, we will demonstrate to participants how basic methodologies with directional statistics and machine learning/deep learning models help in the detection and analysis of craters in our Universe.

[more ▼] In 1997, the Luxembourgish steel company ARBED extinguished the last of its three traditional blast furnaces built between 1965 and 1979 at its production site in Belval, now solely focusing on recycling scrap metal. This marked a milestone in the restructuring of the Luxembourgish steel industry which experienced a far-reaching transformation from mass steel producer and largest employer of the country to a local producer of highly specialized products with a small number of skilled workers beginning in the mid-1970s. This paper traces the history of the three Belval blast furnaces that, despite the conversion of the steel site, managed to prevail to this day. While two of the blast furnaces "Hochofen A" and "Hochofen B" now shape the skyline of the redeveloped urban space and national University campus as industrial monuments, Hochofen C was bought by the Kunming Iron and Steel company in 1996, dismantled and shipped to the Chinese Yunnan province where it remained operational until 2021. Creating three object biographies, this paper compares different approaches to dealing with obsolete industrial artefacts. It analyses (1) the process of de-industrialisation of the Luxembourgish steel industry through which the blast furnaces lost their significance, (2) the classification as cultural heritage and integration into a new urban space, characterized by company, political and public debates and (3) the transaction with China as well as the reception and utilization of HO C at the destination. By examining company records, international reports and media sources, different transnational narratives and contexts of industrial development across time and space are revealed and it is argued that, the blast furnaces have served as symbols of industrialisation, de-industrialisation and re-industrialisation in both Luxembourg and China.

[more ▼] Presentation for the ZZF PhD colloquium of my current (new) book project which explores the history and genealogies of digital history, set within the broader context of the ways in which technology has shaped historical research practices and knowledge production since the late 19th century. The aim is to investigate the intellectual underpinnings of the field we now call digital history by attending to the longue durée of the human-machine encounter in historical research. For over a century, historians have reflected upon the impact of various mechanical aids and computing on their discipline. Along the way, they have debated key epistemological and methodological questions that have resurfaced in our current era of ‘digital history’, yet this is often forgotten. If we accept, however, that historical research practices and knowledge production have always been affected by technology, then how can we qualify what is new in the current moment and what is not? In other words, how can we work towards a self-understanding of the field of digital history that is truly grounded in history?

[more ▼] Nature and humanity have been in constant and varied interactions throughout history and technological epochs. I conjecture that there are benefits to integrating natural characteristics into robot designs for their interactions with humans. I test this conjecture experimentally with a focus on close-range interactions with flying robots, using Research through Design (RtD) and mixed-methods approaches. In my half-PhD seminar, I will discuss the two studies I have carried out, namely: 1) overlaying natural sounds, i.e. birdsong and rain sound, on a noisy flying robot at three proxemic distances (N=56), accepted by ACM THRI journal: https://doi.org/10.1145/3579859; 2) exploring potential usage scenarios of indoor drones (N=66), including investigating the notion of pet drone. In both studies, I found that participants were ambivalent towards the natural characteristics depending on given circumstances. This informs that utilising natural characteristics in human-robot interaction (HRI) may be compelling; however, there are pitfalls, and comprehensive strategies and careful considerations are required. I will also briefly present my research ideas of investigating interactions with bioinspired and biohybrid flying robots for my subsequent studies.

[more ▼] Do the historians gathered in the Tensions of Europe network have a particular relationship to archives, to sources, and to their research materials? What does being a historian of technologies, infrastructures, or networks imply, and is there a singularity regarding sources and archives? It is this relationship to the archives, to the sources, to the historical material at large, to the spatialities, and materialities as well, that this conference invites us to question. The issue of “Surprising Sources” can be understood in two ways: first by reflecting on a source that is surprising in its form (use of a series of stamps, unpublished data, a natively digital archive, material traces like abandoned factory, pipes, etc.), and second by presenting a source that is surprising in its content, such as an unexpected discovery in a source that alters the meaning of the research, adds substance to it, or modifies it.

[more ▼] Les techniques sont inséparables de l’activité humaine. Elles relèvent de l’agir et permettent de produire des objets destinés à différentes finalités matérielles (enfoncer un clou, jouer de la musique, observer les étoiles, tuer...) ou conceptuelles (outils méthodologiques, rituels, algorithmes…). Cela signifie notamment que la technique naît d’une représentation spécifique du monde et du soi, et en crée, par son interaction avec le monde, des nouvelles. A l’interface entre l’homme et (sa représentation du ainsi que son action sur) le monde, elle joue un rôle à la fois fonctionnel ainsi que fictionnel et, de par son influence sur l’interprétation du monde et sa transformation, s’avère être un outil de pouvoir. A l’ère de la cybernétique, des données massives, et du gouvernement algorithmique, la technique cherche à dépasser son statut d’objet institué pour devenir – au moins le veut la nouvelle idéologie – elle-même capable d’instituer un ordre symbolique (technicisé), avec des effets inévitables et encore imprévisibles sur les notions de subjectivité et de système politique, juridique, économique, social. Partant de cette interférence dynamique entre technique et symbolique, nous voudrons soulever la question de savoir de quelle manière la conception de la technique se construit et évolue dans les différentes filières des sciences humaines, avec quels effets sur les interactions entre l’homme et le monde, et avec quelles implications de pouvoir.

[more ▼] Im PhD Projekt an der Universität Luxemburg (Betreuer Martin Uhrmacher) geht es zunächst um die Erstellung eines Corpus der gedruckten Altkarten des Raumes zwischen Mittelrhein und Maas, insbesondere der Territorien des Kurstaats Tier und des Herzogtums Luxemburgs. Das Corpus der existierenden Karten wird klassifiziert und genealogisch strukturiert um Abhängigkeiten zwischen den Karten oder Einflüsse von außen aufzeigen zu können. In einem long durée Ansatz wird der Zeitraum von 1500 bis zum Ende des Ancien Regimes betrachtet, geleitet wird die Analyse der Altkarten durch folgende Fragestellungen: – Welche Quellen liegen den Karten zugrunde? Handelt es sich um ältere gedruckte Karten, die mehr oder weniger exakt kopiert wurden, oder gehen sie auf Landesaufnahmen in der Region zurück? – Welche Abhängigkeiten (ähnlich Netzwerkstrukturen) lassen sich in chronologischer Reihung rekonstruieren? Gibt es Primärkarten, die eine große Anzahl späterer Karten beeinflusst haben? – Wer hat aus welchem Interesse die Herstellung von Karten initiiert? Waren es die regionalen Landesherren im Kontext der frühneuzeitlichen Territorialisierung, oder Gelehrte, die neues geographisches Wissen publizieren wollten, oder waren es kaufmännisch orientierte Verleger, die mehr am Gewinn als an der Aktualität der dargestellten Karteninhalte interessiert waren? – Wie lässt sich der Kartenmarkt des Untersuchungsraums beschreiben? Wer kaufte Karten zu welchem Zweck? – In welchem zeitlichen Abstand wurden territoriale Veränderungen in Karten berücksichtigt und wie wurden diese inhaltlich dargestellt? Ein wesentlicher Aspekt der Untersuchung, der im Vortrag thematisiert werden soll, ist die Aufdeckung von Abhängigkeiten und inhaltlichen Beeinflussungen zwischen Karten des Corpus. Ein „Einfluss“ in diesem Kontext wird unterstellt, wenn beide Karten ein hohes Maß an Ähnlichkeit aufweisen und es eine belegbare oder vermutete Beziehung zwischen den Karten bzw. den Autoren gibt. Die Ähnlichkeit wird mit Hilfe der kartometrischen „Distanz“ zweier Karten berechnet oder – falls die Kartometrie keine Aussage erlaubt – durch eine quantitative Analyse der Toponyme nachgewiesen. Je mehr die Ortsnamen in beiden Karten übereinstimmen, umso mehr kann eine Ähnlichkeit angenommen werden. Ein drittes und besonders trennscharfes Instrument ist der Vergleich kartographischer Besonderheiten und Auffälligkeiten. Allerdings reicht eine konstatierte Ähnlichkeit zweier Karten nicht immer aus, um auch einen Einfluss nachzuweisen, denn schließlich können Karten unabhängig entstanden sein und sich trotzdem ähneln. Deshalb muss zusätzlich eine kartographiehistorische Beziehung im analytischen Vergleich zwischen Karten oder durch Beziehungen zwischen den Autoren nachgewiesen werden. Dieser Nachweis gelingt leicht, wenn die Beziehung gut dokumentiert ist (z.B. durch familiäre Beziehungen, die Übernahme einer Kartenmacherwerkstatt, den Verkauf von Kupferplatten, etc.). Schwieriger wird es, wenn Beziehungen durch Indizienketten nur vermutet werden können.

[more ▼] This paper will explore a key question for historians today: what are the politics of cultural heritage digitisation and its implications for historical research? What are the benefits and opportunities afforded by digitisation and what challenges arise? How do digital resources shape the historical themes, topics, and debates that can be researched, and how might they influence research agendas more broadly? In what ways can they enable us to ask new research questions or open avenues of inquiry that challenge existing master narratives? Can digital resources facilitate research into transnational histories when most digitization projects are still nationally framed? In short, what biases might digital archives introduce in our work and how does that differ from issues of bias and selection in the ‘paper’ archive? To address questions such as these, I will discuss several key parameters of the politics of digitisation set within a broader historical and global context.

Our virtual exhibition, Minett Stories, investigates the multiple – and sometimes contested – histories and identities of the region, as well as those of the people who lived and worked there. Through 21 stories we describe the various transformations of landscapes, places and people, from the region’s rapid industrialisation in the late 19th century to the steel crisis of the 1970s and the subsequent gradual deindustrialisation. Instead of focusing on the narratives of the large ironworks and steel barons, the stories narrate the lives of ordinary people, the "Minettsdäpp".

[more ▼] In the Euclidean case, it is well-known, by Malgrange and Ehrenpreis, that linear differential operators with constant coefficients are solvable. However, what happens, if we genuinely extend this situation and consider systems of linear invariant differential operators, is still solvable? In the case of $\mathbb{R}^n$ (for some positive integer $n$), the question has been proved mainly by Hörmander. We will show that this remains still true for Riemannian symmetric spaces of non-compact type $X=G/K$, in particular for hyperbolic planes. More precisely, we will present a possible strategy to solve this problem by using the Fourier transform and its Paley-Wiener(-Schwartz) theorem for (distributional) sections of vector bundles over $\mathbb{H}^2=SL(2, \mathbb{R})/SO(2)$.

[more ▼] ZeroPM Webinar: \textlessstrong\textgreater\textlessem\textgreaterAre there really 6 million PFAS in PubChem?\textless/em\textgreater\textless/strong\textgreater The increasing concerns about poly and perfluoroalkyl substances (PFAS) and calls for action upon them as a class has spurred intense debates on how to define and enumerate the “PFAS Chemical Space”. There are now \>50 PFAS lists openly available, including the OECD PFAS list of \textasciitilde4700 PFAS (ENV/JM/MONO(2018)7) and the US EPA PFASMASTER list of \>12000 PFAS. However, searching the large open chemical collection PubChem (114 million chemicals, Feb. 2023) reveals that \textlessstrong\textgreater\textlessem\textgreater\>6 million entries\textless/em\textgreater\textless/strong\textgreater match the latest OECD PFAS definition where PFAS “contains at least one alkyl CF$_\textrm2$ group” (ENV/CBC/MONO(2021)25). This webinar will introduce listeners to the new classification browser in PubChem designed to help navigate these incredible numbers, the “PFAS and Fluorinated Compounds in PubChem Tree” (“PubChem PFAS Tree” for short). The current version contains six main sections: OECD PFAS definition (\>6 million PFAS), organofluorine compounds (\>19 million compounds), other diverse fluorinated compounds, OECD PFAS by chemistry (\>7 million PFAS including salts and mixtures), several PFAS collections (from CompTox, NORMAN-SLE, NIST, OntoChem and PubChem) and finally regulatory collections. We will walk listeners through the PubChem PFAS Tree and the many features it offers to help users explore the PFAS space in PubChem and look forward to lively discussions with the audience afterwards.

[more ▼] Avant de constituer une ‘archive’ ou ‘collection’ se déroule une pratique en apparence banale : celle du stockage. C'est à la fois une pratique triviale et technique, qui relève d’usages individuels (stockage de musique, de photos personnelles, de données…) mais aussi collectifs (stockage par les médias eux-mêmes, les institutions patrimoniales…). Katharina Niemeyer et Valérie Schafer reviendront sur le numéro spécial qu’elles ont récemment coordonné et qui analyse la question du stockage dans une perspective historique, médiatique et matérielle. La problématique de la rencontre entre l’analogique et le numérique est ici au cœur de la réflexion : quelles répercussions de ce contexte renouvelé du stockage pour les usagers, pour les industries médiatiques, pour les institutions patrimoniales ou encore pour l’écriture de cette histoire ? Quels défis se présentent aux archivistes ? Comment se négocie le passage entre analogique et numérique, entre continuités et ruptures ? En présentant des exemples (CD-Rom, stockage pair-à-pair, etc.) qui couvrent le stockage par, dans et pour les médias, la rencontre souhaite également engager un échange sur une pratique transversale aux médias et usages médiatiques et sur un sujet inépuisable.

[more ▼] La perspective actionnelle, au centre des cours de langues depuis les années 2000, prend en compte le besoin de communiquer des apprenants. Ces derniers sont habitués à réaliser des tâches en contexte pour communiquer dans la langue cible, alors comment rendre aujourd’hui l’apprentissage du lexique dynamique pour nourrir ces interactions dans le contexte multilingue de l’enseignement secondaire au Luxembourg ? Dans cette communication, nous allons explorer plusieurs ressources (l’art et des applications numériques spécialisées sur le lexique) et les travailler sur différents supports (le téléphone et les tablettes). Ces outils didactisés offrent des stratégies d’enseignement-apprentissage en classe inversée ou en enseignement hybride, tout en permettant -nous le verrons-, de maintenir l’attention des élèves en cours de français. Cette démarche facilite également la mise en place de la pédagogie différenciée auprès d’un public aux niveaux hérétogènes (Français Langue Etrangère, Français Langue Seconde, et Français Langue Maternelle).

[more ▼] We study a dynamic principal-agent model in which the principal is a group whose members hold heterogeneous and evolving values from an agreement with the agent. The principals collectively choose the agent’s offer, which binds all principals if the agent accepts. Learning about the agent’s private information reduces the principals’ conflicts over their joint offer, mitigating a principal’s subsequent losses if she is not decisive. As a consequence, a principal in a group prefers to screen the agent more aggressively than a single principal. We study the dynamics of the principals’ collective choice, and obtain conditions under which decisive members of the group successively trade away their decision-making authority, leading inexorably to the concentration of negotiation power in the hands of a single principal.

[more ▼] The University of Luxembourg (UL) is currently contributing to the most recent reprocessing effort of the International GNSS Service (IGS) Tide Gauge Benchmark Monitoring Working Group (TIGA-WG) with multi-constellation GNSS solutions, including GPS, GLONASS and Galileo. As part of this new reprocessing and reanalysis effort of GNSS data including stations at or near tide gauges worldwide, several model enhancements consistent with the IGS’s recent effort have been incorporated. During 1994 to 2022 the network generally contains data from over 700 stations. The IGS has placed high importance on unifying processing standards because homogeneous and consistent reprocessing of all GNSS data over the complete time span is necessary for estimating useful geophysical parameters, such as long-term trends in station positions. In addition to the reprocessing of the data, the time series analysis strategy is crucial for deriving accurate long-term estimates. In order to obtain the best parameter estimates and the most realistic uncertainties, it is anticipated that a number of stochastic and deterministic models will be fitted to the position time series. Additionally, the stochastic properties of the series will be investigated. Existing automated processes will be updated with the most recent developments in geodetic time series analysis due to the vast number of stations. Through the full reprocessing of all GNSS observations and the state-of-the-art analysis of the daily position time series, this study will be able to obtain highly accurate estimates of horizontal and vertical land movements that can be employed for the most challenging applications such as correcting coastal sea level records for a better understanding in their changes and constraining glacial isostatic adjustment models. During this presentation, we will provide details on the current reprocessing, present preliminary results and a first cross-evaluation of the vertical land movement estimates.
