We examine the complex relationship between money and happiness. We find that both permanent income and wealth are better predictors of life satisfaction than current income and wealth. They matter not only in absolute terms but also in comparative terms. However, their relative impacts differ. The first exerts a comparison effect – the higher the permanent income of the reference group, the lower life satisfaction – the second exerts an information effect – the higher the permanent wealth of the reference group, the higher life satisfaction. We also show that negative transitory shocks to income reduce life satisfaction while transitory shocks to wealth have no effect. Lastly, we analyse the effects of their components and find that not all of them predict life satisfaction: permanent taxes do not matter, while only the value of permanent real estate, financial and business assets do. Finally, we use quantile regression and analyse to what extent our results vary along the well-being distribution, finding the impacts to be larger at lower levels of life satisfaction. [less ▲]

Dieses Kapitel geht der Frage nach, ob Lehrerüberzeugungen und –erwartungen, je nach sonderpädagogischem Förderbedarf variieren. Außerdem wurde deren Einfluss sowohl auf die Gefühle bei Auseinandersetzung mit der Inklusion von unterschiedlichen Schüler*innen, als auch auf die persönliche Bereitschaft Inklusion umzusetzen, untersucht. Die Studien basieren einerseits auf dem Dualen Prozessmodel der sozialen Kognition und betrachten andererseits das Stereotype-Content-Modell, laut dem Wärme und Kompetenz über 80% der Unterschiedlichkeiten in der Personenwahrnehmung erklären. Die Ergebnisse zeigten, dass Überzeugungen und Erwartungen von dem Typ von Förderbedarf beeinflusst werden. Positivere Überzeugungen bezüglich der Schülermerkmale (Wärme und Kompetenz) und höhere Leistungserwartungen waren hierbei mit positiveren Gefühlen und einer stärker ausgeprägten persönlichen Bereitschaft, die Schüler*innen mit sonderpädagogischem Förderbedarf zu inkludieren, verbunden. Abschließend werden die daraus resultierenden Konsequenzen für die Lehreraus- und -weiterbildung abgeleitet und diskutiert. [less ▲]

In verschiedenen europäischen Ländern führt der Wechsel zur Sekundarschule zu einer bedeutsamen Aufgliederung der Bildungswege, welche ein unterschiedlich hohes Schulleistungsniveau der Schüler*innen voraussetzen. Die Akkuratheit der Zuweisung von Sekundarschulformen bestimmt nicht nur die Optionen der Schüler*innen bei späteren Übergangen im Bildungssystem, sondern beeinflusst auch den weiteren beruflichen und persönlichen Werdegang der Schüler*innen. Schüler*innen mit Migrationshintergrund sind auf die höheren sekundären Schulformen unterrepräsentiert. Inwiefern diese Unterrepräsentation auf stereotypgeprägte Leistungserwartungen zurückzuführen ist, ist bis jetzt unklar, denn es lisgt kein Kriterium vor, um die Urteilsakkuratheit adäquat zu messen. In diesem Kapitel wird ein Ansatz beschrieben, ein solches Akkuratheitskriterium zu entwickeln und zu validieren. In einem zweiten Schritt wird das Kriterium angewendet, um den Zusammenhang zwischen stereotypgeprägten Erwartungen und der Akkuratheit der Übergangsentscheidungen zu untersuchen. Das Kriterium erweist sich als valides Maß und könnte so einen wertvollen Ansatz für weitere Untersuchungen der Akkuratheit von Lehrerurteilen darstellen. Obwohl Lehrer*innen im Allgemeinen eine hohe Urteilsakkuratheit aufweisen, bestätigen die Befunde dennoch die Zusammenhänge zwischen stereotypgeprägten Erwartungen und Urteilsverzerrungen. [less ▲]

Task orientation is currently a prominent concept under discussion in primary school di-dactics. It focuses on tasks along which pupils acquire competences on distinct levels of compe-tence. The qualitative empirical study ANONYMOUS pursues the question which conception of task orientation is present in current textbooks in primary science education. The study follows two foci: (i) the introduction of a new category system for the analysis of the task-orientation potential of tasks, based on the further development of existing category systems for analyzing tasks; and (ii) the analysis of 994 task statements in science textbooks with respect to the di-dactic quality of their task orientation. The sample included nine primary science textbooks, four from Germany and five from Luxembourg. Textbooks were selected from the most fre-quently sold series in the respective country. All tasks of the textbooks were analyzed deduc-tively and inductively by four coders in three steps: (i) identifying tasks with task-oriented po-tential; (ii) itemizing different types of task-orientation potential; and (iii) comparing the text-books with respect to country- and period-specific manifestations of task orientation. Analysis indicated that (i) there are few tasks which meet the criteria of task orientation; (ii) distinct types of task orientation can be generated, among which implicit forms dominate; and (iii) dif-ferences occur in the characteristics of task orientation between older and newer textbooks as well as between German and Luxembourgish ones. Central points of discussion ensue from this: the need to develop models for social and cognitive activation for tasks, challenges for school management and professional development for teachers, and support for pupils—in particular high achieving heterogenization.

This paper studies the specificities of the regulation of shadow banking in Europe. It argues that the idiosyncratic features of the EU shadow banking sector call for a different (or indigenized) regulatory approach from that of the US. It highlights striking differences between the EU and the US shadow banking sectors based on both market structure and legal micro-infrastructure of the shadow banking sectors in these two jurisdictions. These different institutional and legal infrastructures of the shadow banking activities, instruments, and entities, as well as the different trajectories in the evolution of the banking and shadow banking sectors in terms of business models, size and composition of actors and transactions can be the driving force behind the differential regulatory treatment of shadow banking in the EU and the US. In highlighting the differences between shadow banking across the Atlantic, this paper focuses on the repo markets, as the main instruments and activities that play a significant role in credit intermediation outside the regulatory perimeter of the traditional or regular banking system. It then discusses one specific segment of the shadow banking entities, i.e., Money Market Funds (MMFs), and highlights the fundamental differences in the structure, functioning, and existing regulatory treatment of the MMFs in the US and the EU. The paper concludes that the market structure, business models, as well as legacy legal and regulatory frameworks of shadow banking (as well as banking) display substantial differences in the US and the EU. The findings in this paper rally against one-size-fits-all approaches to addressing the problems of the shadow banking system worldwide and recommends differentiated and more nuanced regulatory approaches to regulating shadow banking across the Atlantic. By implication, any adoption of the US regulatory framework or recommendations of international fora for the shadow banking sector by the EU regulatory authorities should not overlook these differences.

Early life adversity (ELA) may cause permanent disturbances in brain-body signaling. These disturbances are thought to contribute to physical symptoms and emotional dysregulation in adulthood. The current study investigated the effects of childhood trauma on young adults’ interoceptive accuracy as an indicator of brain-body communication that may be dysregulated by ELA. Sixty-six participants completed an online-questionnaire followed by a laboratory session including the socially-evaluated cold pressor stress test during which ECG, salivary cortisol and interoceptive accuracy were assessed. Childhood trauma was negatively related to interoceptive accuracy (IAc) after the stressor. This stress-effect could not be observed for heart rate and cortisol, which were unrelated to IAc. Participants reporting higher baseline unpleasantness exhibited lower IAc after the stressor, while increases in unpleasantness due to the stressor were associated with higher IAc. Unpleasantness at baseline mediated the effect of childhood trauma on IAc after the stressor. [less ▲]

This paper explores the interface between central banks and cryptocurrencies. Focusing on the European Central Bank (ECB), it identifies the potential threats that the rise of cryptocurrencies would pose to the basic and ancillary tasks of the ECB, in particular, its monetary policy operations and the exercise of its supervisory functions over credit institutions and payment systems. The paper finds that cryptocurrencies can potentially have both direct – through their potential impact on the price stability and monetary policy, and central banks’ monopoly over issuing base money – and indirect effects on central banks, mainly through the institutions and systems that fall under the ECB’s scope of competence. To address the challenges posed by cryptocurrencies, the ECB may take both legal (including supervisory and oversight) measures and non-legal (or technical) measures. With respect to technical measures, the ECB - to the extent falling within the scope of its competence - may focus on improving the efficiency of existing payment systems and addressing the existing frictions in market infrastructures to indirectly affect the cryptocurrency markets. Alternatively, it can venture into issuing Central Bank Digital Currency (CBDC). Regarding legal measures, central banks could envisage regulating cryptocurrencies either directly or indirectly. However, as the most significant potential impact of cryptocurrencies on central banks is likely to be indirect through the impact of cryptocurrencies on the banking and payment systems, and given the limitations on the ECB’s mandate and its regulatory and supervisory tools, it is apposite for the ECB to consider using indirect strategies and tools to influence cryptocurrency markets. This indirect approach can be implemented through the ECB’s existing supervisory and oversight powers over the banking and payment systems. This paper specifies the direct and indirect measures and assesses their merits in addressing the concerns about cryptocurrencies. [less ▲]

Time-dependent Origin–Destination (OD) demand flows are fundamental inputs for Dynamic Traffic Assignment (DTA) systems and real-time traffic management. This work introduces a novel state-space framework to estimate these demand flows in an online context. Specifically, we propose to explicitly include trip-chaining behavior within the state-space formulation, which is solved using the well-established Kalman Filtering technique. While existing works already consider structural information and recursive behavior within the online demand estimation problem, this information has been always considered at the OD level. In this study, we introduce this structural information by explicitly representing trip-chaining within the estimation framework. The advantage is twofold. First, all trips belonging to the same tour can be jointly calibrated. Second, given the estimation during a certain time interval, a prediction of the structural deviation over the whole day can be obtained without the need to run additional simulations. The effectiveness of the proposed methodology is demonstrated first on a toy network and then on a large real-world network. Results show that the model improves the prediction performance with respect to a conventional Kalman Filtering approach. We also show that, on the basis of the estimation of the morning commute, the model can be used to predict the evening commute without need of running additional simulations. [less ▲]

Within the transition from pen-and-paper to digital solutions, many tablet-based note-taking apps have been developed. In addition, sketchnoting, a highly visual form of note-taking, has gained in popularity, especially in teaching and learning. While current solutions already reduce the burden of organizing and searching through stacks of paper, they provide little support in finding additional information related to the notes, and search capabilities are mostly limited to textual queries and content. In this paper, we present a novel solution for digital sketchnoting aimed at enhancing the learning experience of students. In addition to common capabilities such as handwriting recognition, our note-taking app integrates semantic annotation and drawing recognition. Handwritten notes are recognized and passed through concept recognition and entity linking tools to enable a knowledge graph-based integration of contextually relevant learning resources. We extend traditional search capabilities by including the semantic metadata from the related material as well as enabling visual queries to find recognized sketches. Finally, resembling the exchange of paper notes among students, our app allows to share the semantically enhanced notes with other devices. [less ▲]

The mobile app Schnëssen is intended to establish a state-of-the-art digital platform to collect data on the present-day language situation of Luxembourgish by means of crowd-sourcing and to document and present results to a broader public. Users can participate in a large set of audio recordings tasks and in sociolinguistic surveys. By presenting all audio recordings via an interactive map, participants can explore the language variation of their language. In the first year of data collection, around 210.000 recordings could be collected for numerous variation phenomena from all linguistic levels and over 2800 sociolinguistic questionnaires have been filled out. The app allowed us to compile thus the largest systematic spoken language corpus of Luxembourgish. [less ▲]

Für die großflächige, deutschlandweite Kartierung und Analyse der Familiennamen (FamilienN, im Folgenden steht „N“ für Name(n)) stellt bis heute die nach Postleitzahlen gegliederte Datenbank der Telefonanschlüsse, wie sie im Telefonbuch der Deutschen Telekom von 2005 verzeichnet sind die Datenbasis des Projekts 'Deutscher Familiennamenatlas' dar. Im Folgenden werden wir eine neue umfangreiche Datenbasis der deutschen FamilienN vorstellen, die die bisherige um eine historische Dimension erweitern wird. Es handelt sich um die Datenbank der Verlustlisten der Kriegsteilnehmer des Ersten Weltkriegs, die mit ihren rund 7,7 Millionen Namenträgern aus allen Gebieten des damaligen Deutschen Reichs die gesamte FamilienN-Landschaft des ausgehenden 19. Jh. umfassen. Mit dieser neuen Datenbasis wird es möglich sein, die heutige FamilienN-Landschaft mit derjenigen vor 130 Jahren zu vergleichen und damit zum ersten Mal die regionale Festigkeit bzw. Veränderung der FamilienN zu erforschen. Unberührt von den großen europäischen Migrationswellen des 20. Jh. und erst am Beginn der durch die Industrialisierung beschleunigten Urbanisierung, repräsentieren die Verlustlisten die Namenverteilung einer im Vergleich zu heute deutlich weniger mobilen, überwiegend ländlichen Gesellschaft. Über diese neue Kartierungsgrundlage hinaus leisten die Verlustlisten wertvolle Dienste bei der Etymologisierung, bei sprachgeschichtlichen, dialektologischen oder graphematischen Fragestellungen sowie für die Migrationsforschung.

In light of the current tendency of regulating space resources activities through national legislation, this article addresses the validity of such emerging practice under Public International Law (PIL). To this end, the article first recalls the traditional debate between Monism and Dualism about the relationship between municipal and international law. This analysis is further completed by focusing also on the counter-position between two cornerstones of PIL, the principles of State sovereignty and Pacta Sunt Servanda. Next, the article assesses the exposure of national law “integrating” international law, focusing on ex post conflicts between the two sources as regulated by Article 27 of the Vienna Convention on the Law of Treaties. Accordingly, the article will show that States not willing to adapt their national laws will have to face international responsibility under the Draft Articles on State Responsibility for Internationally Wrongful Acts. Based on the above, the article then presents the related legal consequences, both at the international and national levels. Finally, the article closes by assessing the role of interpretative declarations and the defense of persistent objector as possible legal tools for dissenting States. [less ▲]

Over the recent years, Unmanned Aerial Vehicles' (UAVs) technology developed rapidly. In turn shedding light on a wide range of potential civil and commercial applications ranging from mapping and surveillance, parcel delivery to more demanding ones that require UAVs to operate in heterogeneous swarms. However, with the great advantages UAVs bring, they are expected to soon dominate the shared, low-altitude airspace over populated cities, introducing multiple new research challenges in safely managing the unprecedented traffic demands. The main contribution of this work is addressing the complex problem of UAV traffic management at an abstract level by proposing a structure for the uncontrolled low-altitude airspace. The paper proposes a model of the airspace as a weighted multilayer network of nodes and airways and presents a set of experimental simulations of UAV traffic for the verification and validation of the model. Finally, the paper outlines our intended future work. [less ▲]
