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. [less ▲]

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.

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.

www.c2dh.uni.lu The Russian invasion of Ukraine on the 24th of February 2022 shattered long held beliefs and certainties including the idea that all things digital exist in an ephemeral sphere outside of the grim realities of the physical world. Instead, the war emphasized the fragility of servers,data and critical infrastructure to physical threats and their exposure to online attacks. At the same time and thanks to social networks and digital communication tools, new forms of ad-hoc support emerged that gave rise to the agency of individuals in supporting and safeguarding Ukrainian (digital) Cultural Heritage. This round table aims to reflect upon the challenges imposed on these efforts from multiple perspectives – be it from the technical point of view on providing backups and fallback infrastructures up to the impact of data protection regulations and coordination strategies for volunteers. In a discussion between internationally renowned experts we want to take stock in the lessons learned and to understand how to make (digital) cultural heritage more resilient. [less ▲]

Franklin D. Roosevelt recommended that “like the Bible, [the Constitution] ought to be read again and again.” Gustav Heinemann portrayed the Grundgesetz as a “great offering” whose words must become flesh. Nevertheless, does this have any bearing on constitutional adjudication? Although presidents didn’t – and more and more don’t – shy about handling their respective constitutions as bibles, have justices and constitutional scholars proceeded otherwise? Common wisdom may answer yes, they did. The aim of my study is to show that this is not quite the case. I pursue it in reference to two leading liberal democratic constitutional courts, the US Supreme Court and the German Federal Constitutional Court. This happens in three parts: (1) I will engage with court architecture, understood as a testimony to each institution’s articulation for self-justification and self-empowerment; (2) the semantic consecration of constitutional adjudication especially regarding politics, as it took place in the struggles over what was implied by the innovations pushed forward in the contexts of Marbury v. Madison, on the one hand, and of the German Constitutional Court’s Status-Denkschrift, on the other; (3) and legal-methodological debates on the relationship between the Christian Bible and constitutional provisions that run in parallel and connection to these two landmark events. My findings point out that by dint of the disruptive social development that the differentiation between law and politics was and is, constitutional actors in the 19th century United States and 20th century Germany frequently, if not invariably, relied upon religious resources to embed their positions. I interpret this reliance using Hans Blumenberg's phenomenology of history and epochal thresholds and his theory of reoccupations. [less ▲]

Malgré la libre circulation dans l’espace Schengen, la frontiérisation s’est propagée aux régions frontalières en Europe, au plus tard avec la pandémie du Covid-19. Les travaux menés jusqu’à présent sur les fermetures de frontières dans le cadre de la pandémie montrent que les études sur le covidfencing portent principalement sur des questions socio-économiques, de gouvernance et sur la gestion de crise. Le quotidien des habitants des régions frontalières, leur vécu des événements et les identités face à l’autre sont peu pris en compte. La communication traite cette dimension de culture quotidienne pendant la pandémie et analyse la dynamique de rebordering et debordering. Pour ce faire, les exemples de contestation du covidfencing à la frontière luxo-allemande, franco-allemande et germano-polonaise seront discutées en tant que people’s resilience. Ce dernier comprend des protestations, des solidarités ou des actions symboliques qui mettent en évidence les actes de contestation des frontiérisations par les acteurs civils. Les dynamiques de frontiérisation sont des phénomènes récents dans les régions frontalières en Europe et ne sont pas encore pris en compte dans l’étude des régions frontalières. Cependant, il faut s’attendre qu’après la pandémie, les frontiérisations dans les réalités de vie au sein des régions frontalières resteront pertinentes et continuerons à faire l’objet des contestations par ses habitants. L’unilatéralisme politique, l’euroscepticisme persistant ou la montée du populisme dans un contexte de flux migratoires continus n’en sont quelques des facteurs décisifs. C’est dans ce contexte qu’en conclusion seront présentées des perspectives pour l’étude des régions frontalières à l’ère de frontiérisation. [less ▲]

Expertenworkshop am 30./31.08.2022 im Landesarchiv NRW in Duisburg: born digitals und die historische Wissenschaft – Annäherungen an eine Quellenkunde für genuin elektronisches Archivmaterial Zu den grundsätzlichen Kompetenzen von Historiker*innen gehört die methodische Quellenkri-tik. Gleichzeitig ist es gute fachliche Tradition, dass Archivar*innen diese Kompetenz immer schon mit Blick auf die in ihren Häusern überlieferten Unterlagen gefördert haben. Archi-var*innen kennen die überlieferten Unterlagen mit ihren Charakteristika, ihren Besonderhei-ten, ihren Entstehungszusammenhängen u.ä.m. Aus diesem Wissen heraus sind viele Standard-werke zur Akten- oder Quellenkunde entstanden, die die Historiker*innen bei ihrer Forschungs-arbeit unterstützen. Aus einer Vielzahl von Werken seien an dieser Stelle beispielhaft Heinrich Otto Meisner, Aktenkunde, ders., Archivalienkunde, Gerhard Schmid, Akten, Jürgen Klooster-huis, Amtliche Aktenkunde der Neuzeit, Michael Hochedlinger, Urkunden- und Aktenlehre der Neuzeit genannt. Mit der digitalen Transformation der gesamten Gesellschaft seit dem ausgehenden 20. Jahrhun-dert unterliegen auch die klassischen historischen Quellen einem fortlaufenden Digitalisie-rungsprozess: Briefe werden zu E-Mails, Akten zu E-Akten, Karteikarten zu Datensätzen etc. Hinzu treten Quellen rein digitaler Natur, die in der analogen Welt keine vergleichbaren Vorgänger hatten wie Websites oder Vorgangsbearbeitungssysteme (Fachverfahren). Archivar*innen haben bereits erste Erfahrungen mit der Sicherung dieser Unterlagen. Gleichzeitig haben Zeithistori-ker*innen begonnen, diese Unterlagen für ihre Arbeiten zu nutzen. Von einem guten fachlichen Standard im Umgang mit dieser jüngsten Überlieferungsschicht sind aber alle noch entfernt, es fehlen Praxiserfahrungen in der Breite wie in der Tiefe und zwar sowohl bei der Überlieferungs-bildung und der Archivierung als auch bei der Nutzung und der Interpretation. Die digitale Transformation in Gesellschaft und Verwaltung fordert(e) also Archivar*innen heraus, Konzepte und Verfahren zu entwickeln, um genuin elektronisches Schriftgut dauerhaft zu erhalten, also ebenso langfristig zu archivieren wie mittelalterliche Urkunden oder neuzeitliche Verwaltungs-akten. Dabei geht es um nichts Geringeres als die Verhinderung einer umfassend fehlenden Überlieferung aus der Zeit des späten 20. und frühen 21. Jahrhunderts, was zugleich deutlich stärkere archivarische Eingriffe in die Quellengestaltung erfordert, als das bei der analogen Über-lieferung der Fall war. Wenngleich diese Hürde sicherlich noch nicht abschließend genommen ist, so stellt sich gleich-zeitig die Frage: Wird die historische Wissenschaft und werden Archivnutzer*innen in der Lage sein, diese genuin elektronischen Unterlagen, die kein analoges Pendant kennen, zu interpre-tieren? Welche Instrumentarien und Werkzeuge liegen vor, um versiert born digitals kompe-tent einordnen und auswerten zu können? Sind die archivarischen Eingriffe hinreichend nach-vollziehbar, so dass die quellenkritische Analyse der Forschung nicht beeinträchtigt wird. Auch wenn es erste Ansätze dazu geben mag, so fehlt aus Sicht des Landesarchivs NRW eine um-fassende und methodengeleitete Quellenkunde für genuin elektronisches Archivgut, insbeson-dere aus der Verwaltung. Vielfach – so der Eindruck – sind diese Archivalien in der historischen Wissenschaft noch nicht bekannt oder man ist damit noch nicht vertraut. Das Landesarchiv NRW möchte sich daher gemeinsam mit Historiker*innen diesem Desiderat annehmen. Es ist be-strebt, die begonnene Bildung und Nutzung von elektronischer Überlieferung auch mit einer fachlich-theoretischen Diskussion zwischen Forschung und Archiven zu begleiten. Zu diesem Zweck organisiert das Landesarchiv NRW einen Workshop für und von Expert*innen aus der Geschichtswissenschaft und dem Archivwesen, um den quellenkritischen Diskurs zu ge-nuin digitaler Überlieferung zwischen Forschung und Archiven zu fördern und einen Impuls für die Entwicklung einer Quellenkunde zu geben. Dieser Workshop soll zum einen als Bestandsauf-nahme und zum anderen – idealiter – als Grundlage für eine Publikation dienen. Auf der Basis der Kenntnisse von Archivar*innen über die gängigen elektronischen Archivalien einerseits und durch das Bündeln vorhandener Ansätze geschichtswissenschaftlicher Auswertungsmethoden für born digitals andererseits sollen Überlegungen für eine Quellenkunde elektronischer Unterla-gen weiterentwickelt werden. Der Workshop grenzt sich insofern von den üblichen Herangehensweisen in den Digital Humani-ties ab, als dass Forschungsdaten, Digitalisate von analogem Archivgut, Datenbankanalysen und andere Methoden der Recherche in digitalen (Online-)Daten (Data Mining etc.) oder der digita-len Präsentation und Diskussion von Forschungsergebnissen nicht thematisiert werden. Zentral diskutiert werden soll das elektronische Archivgut, das den Großteil des genuin elektronischen Schriftguts aus den anbietungspflichtigen Behörden, also die neue und künftige Überlieferung der öffentlichen Verwaltung darstellt, nämlich elektronische Akten, Fachverfahren, ungeordnete Dateiablagen, daneben aber auch Informationen im Internet und in den Sozialen Medien. In der ersten Sektion „Einführendes und Grundlegendes“ werden Fragestellung und Themenzu-schnitt des Workshops dargelegt sowie die Terminologie aus zwei Perspektiven zur Diskussion gestellt. Ferner wird erörtert, worin die „Digitale Transformation“ in der Verwaltung besteht und was die Konsequenzen für die Generierung von genuin elektronischen Verwaltungsunterla-gen sind: Welche Daten und Informationen entstehen? Worin unterscheiden sich genuin elekt-ronische Unterlagen von den bekannten analogen Verwaltungsakten, was ist das spezifisch Digi-tale? Wie verändern sich Systematik und Aggregation von Verwaltungsdaten? In welchem Maße greifen Archive im Zuge der digitalen Überlieferungsbildung und der elektronischen Archivie-rung in die Daten ein? Welche Bedeutung kommt dabei den signifikanten Eigenschaften, den Metadaten und den Versionierungsangaben zu? In den Sektionen II und III stehen typische und spezifische digitale Objekttypen im Fokus hin-sichtlich der archivierten Formate und Kontexte sowie hinsichtlich der Methoden der quellen-kritischen Einordnung und quellenkundlichen Auswertung. Ausgehend von den Kenntnissen zu diesen Objekten soll u.a. Folgendes diskutiert werden: Welche technischen, verwaltungsorgani-satorischen und archivfachlichen Kenntnisse sind für eine methodenbasierte, wissenschaftliche Interpretation der ausgewählten Unterlagentypen als historische Quellen erforderlich? Welche Anforderungen sollten Archive erfüllen, damit eine quellenkritische Auswertung der elektroni-schen Überlieferung gewährleistet ist? Was muss ein „Werkzeugkasten“ beinhalten, damit er als methodenbasierte „Quellenkunde für genuin elektronisches Archivgut“ dienen und in die Ver-mittlung von Geschichtswissenschaft einfließen kann? Was wäre beispielsweise Inhalt eines Grundseminars „Quellenkunde genuin elektronischen Verwaltungsschriftguts“? Zu diskutieren ist, welche bisherigen „Werkzeuge“ können – ggf. leicht abgewandelt – auch auf born digitals angewandt werden, welche müssen neu entwickelt werden und was kann u.U. aufgrund der Digitalität der Quellen neu erforscht werden. In der Abschlussdiskussion soll neben einem Resümee ein Ausblick auf ein mögliches Publikati-onsprojekt gewagt werden, etwa: Was ist der Bedarf der Geschichtswissenschaft? Welche Art von Quellenkunde wird benötigt? Kann es ein gemeinsames Projekt für eine Quellenkunde ge-ben? Der zweitägige Workshop ist so gestaltet, dass die archivfachlichen Perspektiven mit denen der Geschichtswissenschaft eng verzahnt miteinander im Dialog stehen. Deshalb wird jedes Thema von zwei Impulsreferaten (à ca. 15-20 Minuten) je von einer/m Archivar*in und einer/m Histori-ker*in eingeleitet. In den verbleibenden ca. 30 Minuten ist Raum für die Diskussion. Anders als die vorhergehenden Sektionen ist die Sektion III als „Workshop im Workshop“ organisiert: Die quellenkritische Betrachtung von einerseits E-Akten und andererseits elektronischen Fachver-fahren wird von zwei Archivarinnen vorbereitet und durchgeführt. Daneben sollen gemeinsam konkrete Beispiele von elektronischen Unterlagen angeschaut und diskutiert werden. Die von Dr. Bischoff moderierte Abschlussdiskussion wird zunächst von einem Historiker mit einem Kommentar zur Tagung eingeleitet. [less ▲]

Public History and history didactics are two subdisciplines of history that focus on reaching the world outside the academy. Both put an emphasis on “practising” history while at the same time grounding practice on theoretical reflection and empirical research with the ultimate goal of developing the most effective strategies of reaching diverse audiences to enhance historical knowledge and understanding. This roundtable explores what we mean by international public history and by the internationalization of history didactics, drawing on initiatives such as The Italian Public History Manifesto (2016) issued by the Italian Association of Public History (Associazione Italiana di Public History (AIPH). Our discussion will revolve around questions such as How must we re-shape history didactics and public history so that we take full account of transnational, diasporic and other identities based on class, gender, race, ethnicity, religion, sexuality, or ability? How can we enhance knowledge building globally by embracing different local experiences and perceptions? How do we address imbalances and the traditional North American and European centredness of our subdisciplines? [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 ▲]

Machine leaning (ML), an imposing but not necessarily new method, is living today its golden age by achieving unforeseen results in numerous industrial applications. On the other side, Space Weather (SW), which describes changing environmental conditions in near-Earth space, is becoming more and more important to our society. But how can SW benefit from the ongoing ML revolution? In the last decade, many researchers, like E. Camporeale, showed that SW possesses all the ingredients often required for a successful ML application. Using this large and freely data set of in situ and remote observations collected over several decades of space missions, it is possible to forecast and nowcast solar activity and thus protect our increasing satellites constellations and us! In this talk, we will give a warm introduction to this field and point out a number of open challenges that we believe is worth to discuss and to undertake. [less ▲]

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 case of Rn (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. More precisely, we will present a possible strategy to solve this problem by using the Fourier trans- form and its Paley-Wiener(-Schwartz) theorem for (distributional) sections of vector bundles over X. We will get complete solvability for the hyperbolic plane H2 = SL(2, R)/SO(2) and beyond. This work was part of my doctoral dissertation supervised by Martin Olbrich. [less ▲]
