Unter Experten in Sachen Übersetzungsgeschichte ist Johann Diederich Gries kein Unbekannter. Er zählt z. B. zu den zehn "bedeutende[n] Übersetzerpersönlichkeiten von der frühen Neuzeit bis heute", deren Leben und Werk in der Europäischen Übersetzungsgeschichte von Jörn Albrecht und Iris Plack dargestellt wird. Friedmar Apels von Gottsched und Bode bis Dedecius und Enzensberger reichende "Leseliste zur Geschichte des Übersetzens in Deutschland" umfasst 60 Übersetzer, von Gries werden dessen Calderón- und Tasso-Übersetzungen zur Lektüre empfohlen.
Dorothea Gotfurt, 1907–1995
(2024)
Dorothea Gotfurt kam 1935 als Exilantin nach England. Dort wurde sie zur Übersetzerin. Zwischen 1955 und 1970 veröffentlichte sie vor allem im Scherz-Verlag (Bern), aber auch bei Fischer (Frankfurt/M.), Rowohlt (Reinbek) oder Szolnay (Wien) über dreißig von ihr ins Deutsche gebrachte Romane aus der zeitgenössischen englischsprachigen Literatur.
Die Bibliographie nennt alle in der Deutschen Nationalbibliothek vorhandenen Bücher Grete Fischers. Die Titel wurden mit Ausnahme der drei 1945/46 in Glasgow erschienenen Bücher autoptisch überprüft. Als Verlagslektorin hat sie durch mehrere Jahrzehnte an deutschen und englischen Übersetzungen mitgewirkt, die sich bisher jedoch bibliographisch nicht nachweisen ließen.
Auf Initiative des Schwerpunktes Ökotoxikologie im Masterstudiengang Umweltwissenschaften an der Justus-Liebig-Universität Gießen wurde eine neue Plattform für die Begegnung und Vernetzung der Studierenden untereinander eingerichtet, der sich nun zum ersten Mal jährt. Um mehr Einblicke in das praktische Versuchswesen und Studienangebote anderer Hochschulen zu geben, organisiert der Schwerpunkt Angebotsformate, die über die Vorlesungen hinausgehen. Der »Mittelhessische Tag der Ökotoxikologie« bringt Studierende der Technischen Hochschule Mittelhessen, der Goethe-Universität Frankfurt, der Philipps-Universität Marburg, jüngst auch der Universität Kassel und der JLU am FNU in Homberg (Ohm) zusammen und erlaubt ihnen Einblicke in die ökotoxikologische Forschung und Praxis.

Kinder und Jugendliche beschäftigen sich gerne mit audiovisuellen, auditiven und interaktiven Medien. Das Buch gerät im Mediengeflecht zunehmend in den Hintergrund. Um für die junge Zielgruppe attraktiv zu sein, setzen Verlage auf Bücher, die Themen, Geschichten und Darstellungsweisen aus anderen Medien aufgreifen. Dazu gehören auch die sogenannten Medienbegleitbücher, die in Bezug zu einem Film, einer Serie, einem Hörspiel oder einem digitalen Spiel stehen. Diese Bücher ermöglichen Kindern aufgrund der bereits bekannten Geschichten, Charaktere und Dialoge einen erleichterten Zugang zu Literatur und locken mit besonderen Gratifikationen, die vorlagenfreie Bücher nicht zu bieten haben. Daher sind sie als Lesestoffe auch für die Leseförderung interessant.
Diese Arbeit untersucht daher, welche Stellung Medienbegleitbücher im Kinder- und Jugendbuchmarkt sowie in der Leseförderung haben. Im ersten Teil liegt der Fokus auf der Produktion und Distribution von Begleitbüchern. Mithilfe einer Recherche im Katalog der Deutschen Nationalbibliothek wurden das Marktangebot erarbeitet und Rückschlüsse auf die Entwicklung des Genres gezogen. Jahresbestsellerlisten des Buchreport geben einen Eindruck vom Verkauf der Bücher. Forschungsliteratur zum Thema Lizenzen und Kommunikationspolitik in Verlagen ergänzt den Marktüberblick durch die Perspektive von Handel und Herstellung.
Im folgenden Kapitel werden unter Zuhilfenahme von Forschungsliteratur und Studien die Potenziale der Begleitbücher geschildert. Rezensionen und Bewertungen zu Medienbegleitbüchern auf LovelyBooks und Amazon geben Aufschluss über die Einstellung der Leser*innen und Beiträge in Zeitschriften der Kinder- und Jugendliteratur zeigen die Meinung der Vermittler*innen zu Begleitbüchern.
Der letzte Abschnitt der Arbeit beschäftigt sich mit dem Einsatz der Medienbegleitbücher in der Leseförderung. Stellvertretend für Angebote in der Familie und in Kindertagesstätten wurde die Arbeit der Stiftung Lesen Mainz betrachtet. Eine Analyse der Angebote und ein Experten-Interview geben nähere Einblicke in die Einbindung von Medienbegleitbüchern. Die Didaktik-Forschung gibt Auskunft über die Integration von Medienbegleitbüchern und Medienverbünden in den Unterricht. Im Bereich der außerschulischen Leseförderung wurde der Einsatz von Medienbegleitbüchern in den Lesestunden von Mentor e.V. Mainz mit einer Online-Umfrage unter den Mentor*innen untersucht. Der Katalog der Anna Seghers Bücherei Mainz zeigt das Angebot an Medienbegleitbüchern in Büchereien auf. Der Instagram-Account der Bücherei lässt Rückschlüsse über den Einsatz von Begleitbüchern in Aktionen zu.
Zusammenfassend konnte festgehalten werden, dass Medienbegleitbücher ein wichtiges Segment des Kinder- und Jugendbuchmarktes darstellen, hohe Umsätze generieren können und für den Handel von Bedeutung sind. Aufgrund des vielfältigen Angebots und der verschiedenen Vertriebswege können viele Zielgruppen angesprochen und erreicht sowie Barrieren zum Medium Buch abgebaut werden. Obwohl die Erfahrungen von Familienangehörigen und Mentor*innen belegen, dass sich Begleitbücher positiv auf die Lesemotivation und das Leseverhalten von Kindern und Jugendlichen auswirken können, werden sie in der Leseförderung bislang eher am Rande berücksichtigt. Sie werden zwar empfohlen, aber Konzepte für und Evaluationen von Projekten fehlen. Die Potenziale der Medienbegleitbücher und ihrer Medienverbünde werden daher nicht ausgeschöpft. Medienbegleitbücher sollten zunehmend in den Fokus gerückt und als Chance wahrgenommen werden, Heranwachsende für Bücher zu begeistern und ihre Lesefreude zu wecken.
Evidence of predation pressure on sensitive species by raccoons based on parasitological studies
(2024)
Highlights
• Parasitological analyses were carried out on 108 free-ranging raccoons in Germany.
• Three endoparasite species were newly discovered, alongside 13 parasites already known.
• A high prevalence of the pathogenic nematode Baylisascaris procyonis was identified.
• Uncovering endoparasites provides insights into predation events from the past.
• Stomach contents show serious negative impact of raccoons on native amphibians.
Abstract
To demonstrate predation and potential impacts of raccoons on various species, a total of 108 raccoons from aquatic-associated nature reserves and natural areas in three federal states of Germany, Hesse (n = 36), Saxony-Anhalt (n = 36) and Brandenburg (n = 36), were investigated from a dietary ecological perspective in the present study. Fecal analyses and stomach content examinations were conducted for this purpose. Additionally, as a supplementary method for analyzing the dietary spectrum of raccoons, the parasite fauna was considered, as metazoan parasites, in particular, can serve as indicators for the species and origin of food organisms. While stomach content analyses allow for a detailed recording of trophic relationships solely at the time of sampling, parasitological examinations enable inferences about more distant interaction processes. With their different developmental stages and heteroxenous life cycles involving specific, sometimes obligate, intermediate hosts, they utilize the food web to reach their definitive host. The results of this study clearly demonstrate that spawning areas of amphibians and reptiles were predominantly utilized as food resources by raccoons in the study areas. Thus, common toad (Bufo bufo), common newt (Lissotriton vulgaris), grass frog (Rana temporaria), and grass snake (Natrix natrix) were identified as food organisms for raccoons. The detection of the parasite species Euryhelmis squamula, Isthmiophora melis, and Physocephalus sexalatus with partially high infestation rates also suggests that both amphibians and reptiles belong to the established dietary components of raccoons from an ecological perspective, as amphibians and reptiles are obligate intermediate hosts in the respective parasitic life cycles of the detected parasites. The study clearly demonstrates that raccoons have a significant impact on occurrence-sensitive animal species in certain areas and, as an invasive species, can exert a negative influence on native species and ecosystems.
L'obiettivo del presente articolo è quello di offrire una visione complementare a quella abituale del romanzo "Die Entdeckung der Currywurst" di Uwe Timm in cui vengano privilegiati gli aspetti del romanzo che lo identificano come opera di World Literature. Se fino ad ora il romanzo è stato principalmente letto come un romanzo tedesco di guerra, con questa lettura si intende far emergere gli aspetti che di esso oltrepassano i confini nazionali e linguistici. Per fare questo si osserveranno in breve i punti di contatto fra la WL e la letteratura postcoloniale, dalla quale la WL stessa ha origine. In particolare si concentrerà l'attenzione sugli elementi del romanzo che evidenziano il rapporto con le letterature e culture di oltre confine, come la cornice narrativa, in cui la narrazione principale si iscrive; le contaminazioni letterarie che emergono dal racconto e infine i numerosi esempi di relazione fra centro e periferia. Inoltre, verrà evidenziato come il periodo storico in cui il romanzo è ambientato, ovvero quello della 'Stunde Null', abbia esso stesso dei contatti intrinseci con le teorie postcoloniali. Si mostrerà come la tesi dell'afferenza del presente romanzo alla WL, sia sostenuta dal fatto che anche attraverso romanzi precedenti, Uwe Timm mostra un interesse spiccato nei confronti delle realtà degli altri paesi e continenti e dell’eredità coloniale dell'Europa.
Arbeit und Spiel fungieren im allgemeinen Sprachgebrauch als Gegensätze. Spielen wird im Kontext dieser Oppositionsbeziehung als autotelische Handlung, also als eine freiwillige Beschäftigung mit unproduktivem Charakter, definiert, die primär der Freude oder Entspannung dient. Arbeiten hingegen wird als zweckorientierte Tätigkeit gefasst, die mit Ernsthaftigkeit und Mühsal assoziiert wird. In einer sich verändernden Arbeitswelt lösen sich diese binären Zuordnungen, sofern sie in dieser Schärfe überhaupt jemals bestanden haben, jedoch zunehmend auf. Arbeit und Spiel verschränken sich, sie bilden Hybridformen aus, bei denen sich Verschiebungen von Spielenden zu Arbeitenden und umgekehrt beobachten lassen. Die Etablierung der Spieleindustrie als Wirtschaftsbranche oder die Professionalisierung des Wettkampfsports bringen beispielsweise Formen des Play-as-Work hervor: "Sämtliche Tätigkeiten mit einer unterstellten Wirkabsicht können demnach als Arbeit begriffen werden. Daher können auch aus traditionellen Gründen oder aus Unterhaltungs- und Zerstreuungsgründen ausgeführte Tätigkeiten nunmehr als Arbeit verstanden werden, wenn ihnen eine Wirkabsicht unterstellt werden kann." Zudem werden in Arbeitsbereichen der postfordistischen Wissensökonomie ludische Elemente wie Kreativität, Improvisation oder Risikobereitschaft in einer Abwendung von der normierten Rationalisierung von Arbeit des Taylorismus aufgewertet und spielhaftes Arbeiten ohne kodifizierte Regeln (wieder) als Mittel wirtschaftlicher Produktivität erkannt. Seit den 1990er Jahren lassen sich ferner Tendenzen einer zunehmenden Entgrenzung und Subjektivierung von Erwerbstätigkeit ausmachen; hierbei wird die mit der Industrialisierung entstandene Trennung von Arbeit und Leben abgeschwächt und das Konzept Arbeit neu definiert, denn diese wird nun nicht mehr vornehmlich negativ als Plage oder göttliche Strafe gerahmt, sondern positiv als Mittel der Selbstverwirklichung konnotiert. Arbeit soll infolgedessen spielend von der Hand gehen und Vergnügen bereiten. Auf diese Weise wird eine work-as-play-Mentalität erzeugt, die die Differenz von Ernst und Spiel in der Betrachtungsweise der Handlung festmacht: Es hängt vom Ausführenden ab, ob eine Tätigkeit als Spiel oder als Arbeit klassifiziert wird. So kann letztlich jede Aktivität einfach zum Spiel erklärt werden. [...] Im Fokus dieses Artikels soll jedoch eine andere Form der Hybridisierung von Arbeit und Spiel stehen: die Repräsentation von Büroarbeit im Computerspiel. [...] Untersucht werden soll im Folgenden, welche Inszenierungsstrategien und Spielmechaniken eingesetzt werden, um das Büro spielbar zu machen. Wie wird das Setting für das Gameplay funktionalisiert und wie werden Arbeitsprozesse ludifiziert? Zu welcher Form des Spiels lädt das Büro ein? Welche Aspekte des Büroalltags werden aufgegriffen und welche Erzählungen sowie Figuren werden mit dem Schauplatz verbunden? Des Weiteren soll analysiert werden, wie über die räumliche Ästhetik inhaltliche Aussagen über die kulturelle Bedeutung und gesellschaftliche Wahrnehmung des Büros transportiert werden.
Der Begriff der Verblendung, ein oft implizit immer wiederkehrendes Thema in der Literatur, Philosophie, und auch in der Religion, hat eine komplexe Bedeutungsebene, die es vielleicht wohl zu bewahren gilt, anstatt sie zu fixieren und damit die Lesemöglichkeiten, die er eröffnen kann, zu reduzieren. Das Wort, das Offenes (etwa eine Hingabe an einen Glauben, die auch eine Selbsttäuschung, ein Fehler sein kann, aber auch Mut bedeuten kann) und Verborgenes (eine mehr oder weniger bewusste Täuschung anderer) zugleich andeutet, entzieht sich durch diese doppelte Struktur von 'Oberfläche' und 'Hintergrund' in gewisser Weise, ohnehin einer festen BeDeutungsgebung. In besonderer Weise bleibt der Begriff mit dem als 'Verliebtheit' umschriebenen Zustand als einer ambivalenten un/wahren, irrational und affektiv besetzten, relationalen, inneren Vorstellung und äußeren Projektion des Selbst und eines Anderen verbunden. Der Begriff kann die Hingabe an eine (trügerische) Romantik oder eine (trügerische) Hingabe an eine Romantik meinen, der ein Selbst und ein Anderes in eine affektive Beziehung zueinander setzt, und so auch die Möglichkeit des Unheimlichen, das Hineinbrechen eines Trug(-Bild)-es kennzeichnen. Dies wiederum ist engstens mit Angst und Wut, den oft als destruktiv dargestellten Affekten und affektiv besetzten Effekten verbunden. Verblendung ist somit auch ein Begriff, der Vorstellungen von 'Rationalität' und (affektiv-besetzter) 'Irrationalität', von 'Richtigkeit' und 'Falschheit' beinhaltet.
This paper relies on an unedited and unpublished nineteenth century love correspondence of a heterosexual couple from the German speaking area. The aim of this study is to contribute to the knowledge regarding the nineteenth century love experience of ordinary and unknown lovers. In fact, while there are plenty of books on love correspondences of famous personalities, little research has been dedicated to love letters and romantic experiences of 'ordinary and unknown' people. For this reason the main aim of this article is to shed light on love stories and love experiences that otherwise will fall into the abyss of oblivion. A new theory regarding the love experience in the nineteenth will be proposed: in this century love was perceived more in its material than in its abstract nature; I argue that in the nineteenth love was more about what people did, than to what they said. Lovers are in constant need of material and 'seeable' proof in order to perceive the love of their partners as real and authentic. The examples extrapolated from the following correspondence will corroborate this statement. Furthermore, this article has the purpose to underline the great value of love letters not only from an historical perspective (being evidence of past lives and dynamics), but also and more importantly from a cultural and societal one: analyzing love letters means to acquire knowledge not only about cultural and societal dynamics, but also and more importantly to add knowledge to the love discourse. In fact, they say a lot about the way people talked, expressed and materialized love in their daily lives. Correspondences without any publication in view are the most precious ones because they represent an unregulated and more spontaneous expression 'of the language of the heart'.
E.T.A. Hoffmanns Erzählung "Der Sandmann" ist dank Freuds Interpretation zu einem seiner wichtigsten Werke geworden. Die Novelle, die die Leser mit dem jungen Studenten Nathanael, der mit sich ein Kindheitstrauma trägt, bekannt macht, ist ein komplexes Werk, das auch den weltbekannten Mediziner fasziniert hat. Diese Arbeit befasst sich mit der schon erwähnten Novelle, mit Freuds Artikel "Das Unheimliche" und mit der sehr relevanten Verfilmung aus dem Jahr 2012. Das Motiv des Unheimlichen kommt in dieser Arbeit als eine Kontaktstelle vor, die auf drei verschiedenen Ebenen interpretiert wird: aus der Perspektive des Unheimlichen in der Novelle, aus Sigmund Freuds Perspektive und wie es im Film auftaucht. Ziel dieser Arbeit ist es zu beweisen, dass das Motiv des Unheimlichen in der Verfilmung anders als im Buch begriffen werden kann, d.h. dass Freuds Motiv des Unheimlichen im Text als gruseliger und verwirrender empfunden werden kann.
Der interdisziplinäre Sammelband eröffnet neue Perspektiven auf den Stil als bislang unterkonturierte literaturwissenschaftliche Leitkategorie unter transnationalen, wissens-, gattungs- und sprachgeschichtlichen Gesichtspunkten. Im 18. Jahrhundert zeichnet sich im Nachdenken über Schreibarten eine Neujustierung der Stilkategorie ab, die den Stil zur Reflexionsgröße für ästhetische Diskurse macht. Der Band sondiert die Pluralisierung, Historisierung und Individualisierung der Stilkategorie, die ihr neue literatur- und kulturtheoretische Anwendungsbereiche eröffnet. Die Bewegungen zwischen den Sprachen, Literaturen, Medien und semantischen Feldern erschließt die Publikation, indem sie europäische Vergleichshorizonte eröffnet und literatur- ebenso wie sprachwissenschaftliche Ansätze präsentiert. Damit leistet sie einen Beitrag zum Feld der komparatistisch ausgerichteten Germanistik, insbesondere der Literatur- und Kulturgeschichte des 18. Jahrhunderts und des europäischen Kulturtransfers.
Beyond well-established difficulties with working memory in individuals with attention deficit hyperactivity disorder (ADHD), evidence is emerging that other memory processes may also be affected. We investigated, first, which memory processes show differences in adults and adolescents with ADHD in comparison to control participants, focusing on working and short-term memory, initial learning, interference, delayed and recognition memory. Second, we investigated whether ADHD severity, co-occurring depressive symptoms, IQ and physical fitness are associated with the memory performance in the individuals with ADHD.
We assessed 205 participants with ADHD (mean age 25.8 years, SD 7.99) and 50 control participants (mean age 21.1 years, SD 5.07) on cognitive tasks including the digit span forward (DSF) and backward (DSB), the Rey Auditory Verbal Learning Test (RAVLT), and the vocabulary and matrix reasoning subtests of the Wechsler Abbreviated Scale of Intelligence. Participants with ADHD were additionally assessed on ADHD severity, depression symptoms and cardiorespiratory fitness. A series of regressions were run, with sensitivity analyses performed when variables were skewed.
ADHD-control comparisons were significant for DSF, DSB, delayed and recognition memory, with people with ADHD performing less well than the control participants. The result for recognition memory was no longer significant in sensitivity analysis. Memory performance was not associated with greater ADHD or depression symptoms severity. IQ was positively associated with all memory variables except DSF. Cardiorespiratory fitness was negatively associated with the majority of RAVLT variables.
Individuals with ADHD showed difficulties with working memory, short-term memory and delayed memory, as well as a potential difficulty with recognition memory, despite preserved initial learning.
Targeted protein degradation (TPD) has recently emerged as an exciting new drug modality. However, the strategy of developing small molecule-based protein degraders has evolved over the past two decades and has now established molecular tags that are already in clinical use, as well as chimeric molecules, PROteolysis TArgeting Chimeras (PROTACs), based mainly on ligand systems developed for the two E3 ligases CRBN and VHL. The large size of the human E3 ligase family suggests that PROTACs can be developed by targeting a large diversity of E3 ligases, some of which have restricted expression patterns with the potential to design disease- or tissue-specific degraders. Indeed, many new E3 ligands have been published recently, confirming the druggability of E3 ligases. This review summarises recent data on E3 ligases and highlights the challenges in developing these molecules into efficient PROTACs rivalling the established degrader systems.
Isothermal titration calorimetry (ITC) is a widely used technique for the characterization of protein-protein and protein-ligand interactions. It provides information on the stoichiometry, affinity, and the thermodynamic driving forces of interactions. This chapter exemplifies the use of ITC to investigate interactions between human autophagy modifiers (LC3/GABARAP proteins) and their interaction partners, the LIR motif containing sequences. The purpose of this report is to present a detailed protocol for the production of LC3/GABARAP-interacting LIR peptides using E. coli expression systems. In addition, we outline the design of ITC experiments using the LC3/GABARAP:peptide interactions as an example. Comprehensive troubleshooting notes are provided to facilitate the adaptation of these protocols to different ligand-receptor systems. The methodology outlined for studying protein-ligand interactions will help to avoid common errors and misinterpretations of experimental results.
Die Lincoln-Siedlung in der Wissenschaftsstadt Darmstadt ist sowohl bundesweites Modellprojekt in Sachen nachhaltiger Mobilität als auch Gegenstand verschiedener Forschungsprojekte. Im Projekt NaMoLi II wird die Zufriedenheit der Bewohnenden in der Lincoln-Siedlung mit dem Mobilitätskonzept und seiner Umsetzung analysiert. Des Weiteren wird geprüft, ob und in welcher Form die vorhandenen Rahmenbedingungen eine nachhaltige Mobilität fördern und wie sich die im Quartier bzw. im Umfeld vorhandenen Angebote der Versorgung und sozialen Infrastruktur auf das Mobilitätsverhalten insbesondere neu Zugezogener auswirken. Hierzu hat eine ausgewählte Bevölkerungsgruppe aus der Lincoln-Siedlung über einen Zeitraum von einer Woche Tagebuchprotokolle ihrer täglichen Mobilität geführt. Teilgenommen haben 14 Haushalte mit insgesamt 28 Personen, die zum Zeitpunkt der Erhebung maximal 15 Monate im Quartier gelebt haben. Die Protokolle wurden von allen Haushaltsangehörigen ab dem Grundschulalter geführt, jüngere Kinder sind in den Tagebüchern der Eltern erfasst. Notiert wurden Wegezwecke und Wegeziele, das genutzte Verkehrsmittel, Start- und Ankunftszeit sowie die (geschätzte) Entfernung. Des Weiteren wurden Kennwerte zur Haushaltsstruktur erhoben, zu geänderten Gewohnheiten nach dem Umzug in die Lincoln-Siedlung sowie nach Problemen in der Alltagsmobilität gefragt. Die Ergebnisse der Mobilitätstagebücher bieten einen interessanten Einblick in den Mobilitätsalltag einer spezifischen Teilnahmegruppe, die ein besonderes Interesse an Mobilitätsthemen gezeigt hat und die sich weitgehend nachhaltig in ihrem Alltag bewegt. Das Fahrrad ist das wichtigste Verkehrsmittel, gefolgt von den eigenen Füßen. Die Mehrzahl der Wegeziele liegt innerhalb eines Radius von bis zu zwei Kilometer. Die multimodalen Angebote im Quartier werden gut genutzt. Es hat sich gezeigt, dass die Methode der Tagebuchprotokolle über einen längeren Zeitraum zielführend ist, um Hinweise für die Alltagstauglichkeit des Mobilitätskonzeptes sowie zu dessen Weiterentwicklung bzw. Nachsteuerung zu erlangen.
This study analyses potential consequences of exiting the Targeted Long-Term Refinancing Operations (TLTRO) of the European Central Bank (ECB). Thanks to its asset purchase programs, the Eurosystem still holds plenty of reserves even with a full exit from the TLTROs. This explains why voluntary and mandatory repayments of TLTRO III borrowing went smoothly. Nevertheless, the more liquidity is drained from the banking system, the more important becomes interbank market borrowing and lending, ideally between euro area member states. Right now, the usual fault lines of the euro area show up. The German banking system has plenty of reserves while there are first signs of aggregate scarcity in the Italian banking system. This does not need to be a source of concern if the interbank market can be sufficiently reactivated. Moreover, the ECB has several tools to address possible future liquidity shortages.

Das Ziel der BMBF-finanzierten Forschungsprojekte „Nachhaltige Mobilität in Lincoln 1“ und „Nachhaltige Mobilität in Lincoln 2“ ist es, Erkenntnisse zu Veränderungen im Mobilitätsverhalten von Personen zu erlangen, die in ein autoreduziertes Quartier umziehen. Dazu wurden zwei aufeinander aufbauende Vollbefragungen der erwachsenen Bewohner*innen der autoreduzierten Lincoln-Siedlung in Darmstadt durchgeführt. Im Rahmen der ersten Befragung im Jahr 2020 wurden 1.140, im Rahmen der zweiten Befragungswelle, 2021, 1.614 Fragebögen verteilt. Der Rücklauf belief sich 2020 auf n = 166 (14,6 %), in 2021 auf n = 231 (14,3 %). Der vorliegende Bericht beschreibt das methodische Vorgehen im Rahmen der Befragungen. Hierfür wird auf das besondere Panel-Design der Studie eingegangen. Dieses ermöglicht sowohl Einblicke in den Umzug in die Siedlung, als auch in das Leben in der Siedlung im Verlauf eines Jahres, und die damit einhergehenden Veränderungen im individuelle Mobilitätsverhalten. Der Bericht stellt dazu die zentralen Inhalte des Fragebogens vor und erläutert die Durchführung der Befragungen. In deren Rahmen wurden die Bewohner*innen der Lincoln-Siedlung insgesamt dreimal kontaktiert. Um die Bereitschaft zur Teilnahme zu steigern, wurden im Vorfeld der Erhebungen mittels einer Pressemitteilung auf die Befragung aufmerksam gemacht und Ankündigungsschreiben in die Briefkästen der Bewohner*innen verteilt. Eine Woche nach der eigentlichen Fragebogenverteilung wurden Erinnerungsschreiben verteilt. Ferner geht der Methodenbericht auf den Umgang mit dem Rücklauf sowie auf die Datenaufbereitung und - eingabe ein, bevor die soziodemographischen Daten der Teilnehmer*innen auf ihre Repräsentativität geprüft werden.
Almost ten years after the European Commission action plan on building a capital markets union (CMU) and despite incremental progress, e.g. in the form of the EU Listing Act, the picture looks dire. Stock exchanges, securities markets, and supervisory authorities remain largely national, and, in many cases, European companies have decided to exclusively list overseas. Notwithstanding the economic and financial benefits of market integration, CMU has become a geopolitical necessity. A unified capital market can bolster resilience, strategic autonomy, and economic sovereignty, reduce dependence on external funding, and may foster economic cooperation between member states.
The reason for the persistent stand-still in Europe’s CMU development is not so much the conflict between market- and state-based integration, but rather the hesitancy of national regulatory and supervisory bodies to relinquish powers. If EU member states wanted to get real about CMU (as they say, and as they should), they need to openly accept the loss of sovereignty that follows from a true unified capital market. Building on economic as well as historical evidence, the paper offers viable proposals on how to design competent institutions within the current European framework.
This note outlines the case for speedy capital market integration and for the adoption of a common regulatory framework and single supervisory authority from a political economy perspective. We also show the alternative case for harmonization and centralization via regulatory competition, elaborating how competition between EU jurisdictions by way of full mutual recognition may lead to a (cost-)efficient and standardized legal framework for capital markets. Lastly, the note addresses the political economy conflict that underpins the implementation of both models for integrating capital markets. We point out that, in both cases, national authorities experience a loss of legislative and jurisdictional competence at the national level. We predict that any plan to foster a stronger capital market union, following an institution based or a market-based strategy, will face opposition from powerful national stakeholders.
The economic rise of China has changed the global economy. The authors explore China’s transformation from a low-cost manufacturing hub to an increasingly innovation- and service-driven economy. Major growth drivers for the period 2010-2025 are analysed, including the paradigms of “Made in China” and the “Dual Circulation Strategy”. The export intensity of China’s economy is declining overall, with a tendency towards greater regional diversification and a gradual decoupling from North America and the European Union. At the same time, trade and investment activities are increasingly geared to the Belt and Road Initiative. Furthermore, labour and energy cost advantages for manufacturing operations in China are likely to diminish in the coming years, calling into question China’s attractiveness as a global manufacturing hub. In this regard, the further development of regional and industrial clusters is pivotal for China to enhance its global competitiveness and remain an attractive destination for foreign direct investment (FDI) in the medium term. On the other hand, high productivity in science and technology and rich deposits of critical minerals put China in a favourable position in advanced industries. Important challenges include the still wide development gap between rural and urban areas, the structural mismatch in the labour market, with persistently high youth unemployment, and the race to achieve carbon neutrality by 2060.
Highlights
• Family structure transitions decrease academic school track attendance among children of less educated parents.
• Children of highly educated fathers in single-mother families also have lower outcomes.
• Reduced income and increased exposure to poverty are relevant mediators.
• There is no cumulative disadvantage linked to a further transition to a stepfamily.
• Previous parental separation does not affect educational outcomes for children residing with a highly educated stepfather.
Abstract
Recent research has documented that the effect of parental separation on children’s educational outcomes depends on socioeconomic background. Yet, parental separation could lead to a stable single-parent family or to a further transition to a stepfamily. Little is known about how the effect of family structure transitions on educational outcomes depends on the education of parents and stepparents, and there has been limited empirical research into the mechanisms that explain heterogeneity in the effects of family transitions. Using longitudinal data from the German Socio-Economic Panel and models with entropy balancing and sibling fixed effects, I explore the heterogeneous effects of family transitions during early and middle childhood on academic secondary school track attendance, grades and aspirations. I find that family transitions only reduce the academic school track attendance among children of less educated parents living in stepfamilies or with a single mother after parental separation, and among children of highly educated fathers living in single-mother families. The mechanisms that partly explain these effects relate to reduced income and exposure to poverty after parental separation. The findings underscore the importance of considering the stepparent's educational level, indicating that the adverse consequences of parental separation on educational outcomes are mitigated when a highly educated stepfather becomes part of the family. Overall, these findings align more closely with the resource perspective than the family stability perspective.

• Pre-service teachershave stereotypes towards pupils with autism, Down syndrome and dyslexia.
• Pupils with Down syndrome, autism and dyslexia are associated with distinctive stereotypes.
• These stereotypes can be classified in three resp. four different dimensions.
Abstract
Stereotypes about pupils with special educational needs are prevalent both in society and among pre- and in-service teachers. However, little is known about the specific stereotypes pre-service teachers associate with autistic pupils, pupils with Down syndrome, and pupils with dyslexia. We explored these in two studies. Study 1 (N=13) involved qualitative interviews to identify potential stereotype content. Study 2 (N=213) used these findings to create a questionnaire to quantify these stereotypes. We found distinct stereotypes associated with all three groups of pupils. For successful inclusion, teachers must recognize the uniqueness of each pupil, including those with different diagnoses.
Research around the “glass escalator” demonstrates that men receive promotions faster than women in women-dominated occupations. However, it remains unclear how overall establishment composition affects the glass escalator. We use German longitudinal linked employer-employee data (LIAB) between 2012 and 2019 to examine how occupational and establishment gender composition shape gender differences in promotions to management. Establishment gender composition moderates the glass escalator, meaning women's mobility disadvantages in women-dominated jobs are most pronounced in men-dominated establishments. We hypothesize that changing occupational status is a central mechanism: When occupations mirror the composition of the establishment, their status increases locally. Higher occupational status offsets lower leadership expectations attributed to women and increases women's promotion odds relative to their male colleagues.
PET probes targeting fibroblasts are frequently used for varying applications in oncology. In recent years, the clinical spectrum has been expanded towards cardiovascular medicine, e.g., after myocardial infarction, in aortic stenosis or as a non-invasive read-out of atherosclerosis. We herein provide a brief overview of the current status of this PET radiotracer in the context of cardiovascular disease, including translational and clinical evidence. In addition, we will also briefly discuss future applications, e.g., the use of fibroblast-targeting PET to investigate bilateral organ function along the cardiorenal axis.
Interferon-stimulated gene-15 (ISG15) is an interferon-induced protein with two ubiquitin-like (Ubl) domains linked by a short peptide chain, and the conjugated protein of the ISGylation system. Similar to ubiquitin and other Ubls, ISG15 is ligated to its target proteins with a series of E1, E2, and E3 enzymes known as Uba7, Ube2L6/UbcH8, and HERC5, respectively. Ube2L6/UbcH8 plays a literal central role in ISGylation, underscoring it as an important drug target for boosting innate antiviral immunity. Depending on the type of conjugated protein and the ultimate target protein, E2 enzymes have been shown to function as monomers, dimers, or both. UbcH8 has been crystalized in both monomeric and dimeric forms, but the functional state is unclear. Here, we used a combined approach of small-angle X-ray scattering (SAXS) and nuclear magnetic resonance (NMR) spectroscopy to characterize UbcH8′s oligomeric state in solution. SAXS revealed a dimeric UbcH8 structure that could be dissociated when fused with an N-terminal glutathione S-transferase molecule. NMR spectroscopy validated the presence of a concentration-dependent monomer-dimer equilibrium and suggested a backside dimerization interface. Chemical shift perturbation and peak intensity analysis further suggest dimer-induced conformational dynamics at ISG15 and E3 interfaces - providing hypotheses for the protein′s functional mechanisms. Our study highlights the power of combining NMR and SAXS techniques in providing structural information about proteins in solution.

Abstract
Marburg virus, a member of the Filoviridae, is the causative agent of Marburg virus disease (MVD), a hemorrhagic fever with a case fatality rate of up to 90 %. Acute kidney injury is common in MVD and is associated with increased mortality, but its pathogenesis in MVD remains poorly understood. Interestingly, autopsies show the presence of viral proteins in different parts of the nephron, particularly in proximal tubular cells (PTC). These findings suggest a potential role for the virus in the development of MVD-related kidney injury. To shed light on this effect, we infected primary human PTC with Lake Victoria Marburg virus and conducted transcriptomic analysis at multiple time points. Unexpectedly, infection did not induce marked cytopathic effects in primary tubular cells at 20 and 40 h post infection. However, gene expression analysis revealed robust renal viral replication and dysregulation of genes essential for different cellular functions. The gene sets mainly downregulated in PTC were associated with the targets of the transcription factors MYC and E2F, DNA repair, the G2M checkpoint, as well as oxidative phosphorylation. Importantly, the downregulated factors comprise PGC-1α, a well-known factor in acute and chronic kidney injury. By contrast, the most highly upregulated gene sets were those related to the inflammatory response and cholesterol homeostasis. In conclusion, Marburg virus infects and replicates in human primary PTC and induces downregulation of processes known to be relevant for acute kidney injury as well as a strong inflammatory response.
Background: Urachal cancer (UrC) is a rare disease with limited availability of representative incidence and clinical data. Although, the prevalence is accounting for less than 1% of bladder tumors, the 5-year survival rate is around only 50% for patients with resectable tumors, and even worse for patients with metastatic disease. Due to the lack of comprehensive prospective studies, our current knowledge of UrC is still limited.
Objective: The present study aimed to summarize the available registry-based studies with unselected UrC patients to evaluate its incidence and clinicopathological characteristics.
Material and methods: We conducted a systematic literature search of registry-based UrC publications on the 15th of May 2023 in 5 databases, which identified 4,748 publications. After duplicate removal and selection by 2 independent investigators, 6 publications proved to be appropriate for the final meta-analysis. Estimated incidence and clinicopathological parameters were extracted.
Results: Estimated incidence ranged between 0.022 and 0.060/ 100.000 person-years, with the highest occurrence in Japan and the lowest in Canada, while the random effect model calculated an overall incidence rate of 0.04 (95%CI: 0.03–0.05) 100.000 person-years. The median age at first diagnosis was 60 years (range: 58–64). The female to male ratio was 2:3. Lymph node or distant metastases were present in 9% and 14% of patients. The predominant tumour type was adenocarcinoma (86%) followed by urothelial carcinoma (12%) and squamous cell carcinoma (2%). The 5-year survival rate was 51.0% with 95%CI: 45.2–57.4.
Conclusions: Our study provides an up-to-date comparison of estimated incidence rates between 6 countries of 3 continents based on rigorously selected registry-based studies. The results suggest low incidence rates for UrC with considerable geographic differences. The present meta-analysis provides unbiased registry-based data on the incidence, clinicopathological parameters and survival of UrC.
Highlights
• Parents with and without migration background differ in educational knowledge.
• Parents with migration background have less educational knowledge on average.
• Variations in educational knowledge by immigrant groups.
• Social and cultural resources are central to explaining knowledge differences.
• Acculturation strategies prove to be of little relevance.
Abstract
Although extant research persistently highlights the importance of information for educational decision-making, better understanding the existence of, and the underlying reasons for, informational differences between immigrant and non-immigrant parents is important. This study examines the differences in the level of information between immigrant and non-immigrant parents of third graders just before they make probably their most important educational decision in the German education system. We draw on approaches highlighting the importance of resources and parents’ acculturation to explain the informational differences between immigrant and non-immigrant parents. Employing linear regression and probability models on data from the National Educational Panel Study in Germany (N = 3961), we demonstrate that all immigrant groups, particularly those from Turkey, the former Yugoslavia, the Middle East, and northern Africa, are significantly less informed than parents without own immigration experience. This result is evident both in our overall test and in various domains of the test, which analyze different aspects of information relevant to parents’ educational decision-making. Furthermore, different endowments with social and cultural capital largely explain the informational differences between parents with and without an immigrant background. In contrast, different acculturation strategies are almost negligible in explaining the differences in the level of information. Our findings provide important insights for research on migration-related inequalities in educational decision-making and for developing interventions to improve migrant parents’ ability to make well-informed and thus intended educational decisions.
Understanding the underlying mechanisms that link psychopathology and physical comorbidities in schizophrenia is crucial since decreased physical fitness and overweight pose major risk factors for cardio-vascular diseases and decrease the patients’ life expectancies. We hypothesize that altered reward anticipation plays an important role in this. We implemented the Monetary Incentive Delay task in a MR scanner and a fitness test battery to compare schizophrenia patients (SZ, n = 43) with sex- and age-matched healthy controls (HC, n = 36) as to reward processing and their physical fitness. We found differences in reward anticipation between SZs and HCs, whereby increased activity in HCs positively correlated with overall physical condition and negatively correlated with psychopathology. On the other handy, SZs revealed stronger activity in the posterior cingulate cortex and in cerebellar regions during reward anticipation, which could be linked to decreased overall physical fitness. These findings demonstrate that a dysregulated reward system is not only responsible for the symptomatology of schizophrenia, but might also be involved in physical comorbidities which could pave the way for future lifestyle therapy interventions.
From hunting and foraging to clearing land for agriculture, humans modify forest biodiversity, landscapes, and climate. Forests constantly undergo disturbance–recovery dynamics and understanding them is a major objective of ecologists and conservationists. Chronosequences are a useful tool for understanding global restoration efforts. They represent a space-for-time substitution approach suited for the quantification of the resistance of ecosystem properties to withstand disturbance and the resilience of these properties until reaching pre-disturbance levels. Here we introduce a newly established chronosequence with 62 plots (50 ⍰ 50 m) in active cacao plantations and pastures, early and late regeneration, and mature old-growth forests, across a 200 km2 area in the extremely wet Chocó rainforest. Our chronosequence covers by far the largest total area of plots compared to others in the Neotropics. Plots ranged from 159–615 masl in a forested landscape with 74 ± 2.8 % forest cover within a 1-km radius including substantial old-growth forest cover. Land-use legacy and regeneration time were not confounded by elevation. We tested how six forest structure variables (maximum tree height and DBH, basal area, number of stems, vertical vegetation heterogeneity, and light availability), aboveground biomass (AGB), and rarefied tree species richness change along our chronosequence. Forest structure variables, AGB, and tree species richness increased with regeneration time and are predicted to reach similar levels to those in old-growth forests after ca. 30–116, 202, and 108 yrs, respectively. Compared to previous work in the Neotropics, old-growth forests in Canandé accumulate high AGB that takes one of the largest time spans reported until total recovery. Our chronosequence comprises one of the largest tree species pools, covers the largest total area of regenerating and old-growth forests, and has higher forest cover than other Neotropical chronosequences. Hence, our chronosequence can be used to determine the time for recovery and stability (resistance and resilience) of different taxa and ecosystem functions, including species interaction networks. This integrative effort will ultimately help to understand how one of the most diverse forests on the planet recovers from large-scale disturbances.
We create an alternative version of the present utility value formula to explicitly show that every store-of-value in the economy bears utility-interest (non-pecuniary income) for ist holder regardless of possible interest earnings from financial markets. In addition, we generalize the well-known welfare measures of consumer and producer surplus as present value concepts and apply them not only for the production and usage of consumer goods and durables but also for money and other financial assets. This helps us, inter alia, to formalize the circumstances under which even a producer of legal tender might become insolvent. We also develop a new measure of seigniorage and demonstrate why the well-established concept of monetary seigniorage is flawed. Our framework also allows us to formulate the conditions for liability-issued money such as inside money and financial instruments such as debt certificates to become – somewhat paradoxically – net wealth of the society.
Highlights
• CD62p + exosomes were significantly increased in septic polytrauma-patients, while CD40+, as well as CD49e + exosomes were diminished.
• Exosomal IL-6 concentration in septic patients reflects the systemic IL-6.
• Exosomal IL-10 concentration seemed to be constant in patients and healthy controls.
• Decrease of miR-21 in exosomes was associated with the development of sepsis, while exosomal miR-93, miR-155 and miR-92a were not specifically altered.
Abstract
Sepsis as a severe systemic inflammation leads oftentimes to organ dysfunction and subsequently to death. In polytrauma patients, septic complications represent with 45% the predominant cause of late death and are responsible for extremely high costs in the healthcare system. Therefore, clinicians have to detect as early as possible the begin of sepsis to improve the patient's outcome. One new promising diagnostic tool to diagnose septic complications in polytraumatized patients are exosomes.
Plasma samples from polytraumatized patients (Injury Severity Score (ISS) ≥16) which developed sepsis (n = 10) and without sepsis (n = 10), were collected at emergency room (ER), 24h and 5 days after trauma. The EVs subpopulations were investigated by a bead-based multiplex flow cytometry measurement of surface epitopes and were compared with plasma EVs from healthy controls (n = 10). Moreover, exosomal cytokine concentrations were measured via high-sensitive ELISA and were correlated with systemic concentrations. For miRNA cargo analysis, we analysed the miRNAs miR-1298-5p, miR-1262, miR-125b-5p, miR-92a-3p, miR-93-5p, miR-155-5p and miR-21-5p and compared their exosomal concentrations by means of RT-qPCR.
CD62p + exosomes were significantly increased in septic polytrauma-patients (p ≤ 0.05), while CD40+exosomes, as well as CD49e + exosomes were diminished (p ≤ 0.05). Furthermore, we observed that the exosomal IL-6 concentration reflects the systemic IL-6 concentration (r2 = 0.63) and did not significantly alter between patients with and without sepsis. The exosomal IL-10 concentration seemed to be constant in all patients and healthy controls. We observed that a decrease of miR-21-5p in exosomes was associated with the development of sepsis (p ≤ 0.05), while exosomal miR-93-5p, miR-155-5p and miR-92a-3p were not specifically altered in septic patients.
Taken together, the present study in polytraumatized patients demonstrated that the development of sepsis is associated with an increase of CD62p + exosomes. Furthermore, the exosomal cargo was changed in septic patients: miR-21-5p was diminished.
We prove that the projectivized strata of differentials are not contained in pointed Brill-Noether divisors, with only a few exceptions. For a generic element in a stratum of differentials, we show that many of the associated pointed Brill-Noether loci are of expected dimension. We use our results to study the Auel-Haburcak Conjecture: We obtain new non-containments between maximal Brill-Noether loci in Mg. Our results regarding quadratic differentials imply that the quadratic strata in genus 6 are uniruled.
Highlights
• Artificial intelligence systems for mechanically ventilated patients are increasing.
• The clinical and financial impact of these models are often unexamined.
• We developed a generic health-economic model for artificial intelligence systems.
• This model assesses the cost-effectiveness for many different scenarios.
• The developed framework is easily adjustable to other (clinical) situations.
Abstract
Purpose: The health and economic consequences of artificial intelligence (AI) systems for mechanically ventilated intensive care unit patients often remain unstudied. Early health technology assessments (HTA) can examine the potential impact of AI systems by using available data and simulations. Therefore, we developed a generic health-economic model suitable for early HTA of AI systems for mechanically ventilated patients.
Materials and methods: Our generic health-economic model simulates mechanically ventilated patients from their hospitalisation until their death. The model simulates two scenarios, care as usual and care with the AI system, and compares these scenarios to estimate their cost-effectiveness.
Results: The generic health-economic model we developed is suitable for estimating the cost-effectiveness of various AI systems. By varying input parameters and assumptions, the model can examine the cost-effectiveness of AI systems across a wide range of different clinical settings.
Conclusions: Using the proposed generic health-economic model, investors and innovators can easily assess whether implementing a certain AI system is likely to be cost-effective before an exact clinical impact is determined. The results of the early HTA can aid investors and innovators in deployment of AI systems by supporting development decisions, informing value-based pricing, clinical trial design, and selection of target patient groups.
Highlights
• Gender cues are defined differently across languages.
• We propose a new refined and standardized definition of gender transparency.
• Gender transparency is quantifiable with values that match theoretical expectations.
• We present the first quantitative method to measure the gender transparency of languages.
Abstract
Languages can express grammatical gender through different ortho-phonological regularities present in nouns (e.g., the cues “-o” and “-a” for the masculine and the feminine respectively in Italian, Portuguese, or Spanish). The term “gender transparency” was coined to describe these regularities (Bates et al., 1995). In gendered languages, we can hence distinguish between transparent nouns, i.e., those displaying form regularities; opaque nouns, i.e., those with ambiguous endings; and irregular nouns, i.e., those that display the typical form regularities but are associated with the opposite gender. Following a descriptive analysis of such regularities, languages have been recently classified according to their degree of gender transparency, which seems relevant in regard to gender acquisition and processing. Yet, there are certain inconsistencies in determining which languages are overall transparent and which are opaque. In particular, it is not clear whether some other complex regularities such as derivational suffixes are also “transparent” cues for gender, what really constitutes an “opaque” noun, or which role orthography and morphology have in transparency. Given the existing inconsistencies in classifying languages as transparent or opaque, this work introduces a proposal to assess gender transparency systematically. Our methodology adapts the standardized factors proposed by Audring (2019) to analyse the relative complexity of gender systems. Such factors are adapted to gender transparency on the basis of the literature on gender acquisition and processing. To support the feasibility of such a proposal, the concepts have been instantiated in a quantitative model to obtain for the first time an objective measure of gender transparency using European Portuguese and Dutch as instances of target languages. Our results coincide with the theoretically expected outcome: European Portuguese obtains a high value of gender transparency while Dutch obtains a moderately low one. Future adaptations of this model to the gender systems of other languages could allow the continuum of gender transparency to sustain robust predictions in studies on gender processing and acquisition.
Invitation, to exi(s)t
(2024)
This joint piece aspires to be a dialogue. In a dialogue, people speak and, most importantly, listen, from their respective positions. Drawing from Trinh T. Minh-ha's notion of speaking nearby, Dulley and Streva reflect on the relationship between authorship, authority, and authoritarianism; the parallel between listening and reading, on the one hand, and speaking and writing, on the other hand; the entanglement between disciplinary systems of knowledge and colonial structures of power; the opacity of others and the imperialistic drive to reduce them to transparency; the supposed subject of knowledge and the void. As they converse on these matters, they speak nearby authors from both the so-called Global South and the so-called Global North who are thus juxtaposed, further developed, and displaced towards a politics and ethics of fugitivity. What follows is an invitation to exi(s)t.
We use a structural VAR model to study the German natural gas market and investigate the impact of the 2022 Russian supply stop on the German economy. Combining conventional and narrative sign restrictions, we find that gas supply and demand shocks have large and persistent price effects, while output effects tend to be moderate. The 2022 natural gas price spike was driven by adverse supply
shocks and positive storage demand shocks, as Germany filled its inventories before the winter. Counterfactual simulations of an embargo on natural gas imports from Russia indicate similar positive price and negative output effects compared to what we observe in the data.
The EU Commission proposed a regulation on artificial intelligence (AI) on 21 April 2021, which categorizes the use of AI in “social credit” as a prohibited application. This paper examines the definition and structure of the Social Credit System in China, which comprises various systems operating at different levels and sectors. The analysis focuses on two main subsystems: the database and one-stop inquiry platform for financial credit records, and the social governance tool designed to facilitate legal and political compliance. The development of the commercial customer credit reference is also explored. This paper further discusses the impacts and concerns associated with the implementation of the Chinese social credit system to raise awareness. The objective is to offer insights from the existing system and contribute to the ongoing discussion on regulating AI applications in social credit within the EU.
Customer loyalty is a critical measure for success, showing if a firm's product is received well by its customers. To understand its development over time, two fundamental questions must be answered: (I) How will current customers' loyalty develop, and (II) will new customers' loyalty differ from current customers' loyalty? The authors empirically answer these questions based on a data set including ~500 B2B web technologies with jointly ~325 million customers spanning over 24 years. They show that loyalty hardly develops and, if so, it rather decreases than increases. The loyalty of current customers rarely changes and, if so, rather increases than decreases. New customers are most likely less loyal than current customers. These results show that by failing to account for these underlying developments, stakeholders, in most cases, draw the wrong conclusions about product value measured via customer lifetime value.
Existing table retrieval approaches estimate each table’s relevance for a particular information need and return a ranking of the most relevant tables. This approach is not ideal since the returned tables often include irrelevant data and the required information may be scattered across multiple tables. To address these issues, we propose the idea of fine-grained structured table retrieval and present our vision of R2D2, a system which slices tables into small tiles that are later composed into a structured result that is tailored to the user-provided information need. An initial evaluation of our approach demonstrates how our idea can improve table retrieval and relevant downstream tasks such as table question answering.
The significance of data and Artificial Intelligence (AI) has a profound impact on all industries, presenting both challenges and opportunities. Given its power and relevance, AI has not gone unnoticed in the public affairs sector. The upcoming German federal election in 2025 brings discussions about AI to the forefront, raising questions about the extent to which data will drive the public affairs field and how it will be handled.
