 Machine learning based methods for diagnosis and progression prediction of COVID-19 from imaging data have gained significant attention in the last months, in particular by the use of deep learning models. In this context hundreds of models where proposed with the majority of them trained on public datasets. Data scarcity, mismatch between training and target population, group imbalance, and lack of documentation are important sources of bias, hindering the applicability of these models to real-world clinical practice. Considering that datasets are an essential part of model building and evaluation, a deeper understanding of the current landscape is needed. This paper presents an overview of the currently public available COVID-19 chest X-ray datasets. Each dataset is briefly described and potential strength, limitations and interactions between datasets are identified. In particular, some key properties of current datasets that could be potential sources of bias, impairing models trained on them are pointed out. These descriptions are useful for model building on those datasets, to choose the best dataset according the model goal, to take into account the specific limitations to avoid reporting overconfident benchmark results, and to discuss their impact on the generalisation capabilities in a specific clinical setting.

While the ``hierarchy of science'' has been widely analysed, there is no corresponding study of the status of subfields within a given scientific field. We use bibliometric data to show that subfields of mathematics have a different ``standing'' within the mathematics community. Highly ranked departments tend to specialize in some subfields more than in others, and the same subfields are also over-represented in the most selective mathematics journals or among recipients of top prizes. Moreover this status of subfields evolves markedly over the period of observation (1984--2016), with some subfields gaining and others losing in standing. The status of subfields is related to different publishing habits, but some of those differences are opposite to those observed when considering the hierarchy of scientific fields. We examine possible explanations for the ``status'' of different subfields. Some natural explanations -- availability of funding, importance of applications -- do not appear to function, suggesting that factors internal to the discipline are at work. We propose a different type of explanation, based on a notion of ``focus'' of a subfield, that might or might not be specific to mathematics. [less ▲]

The COVID-19 took by surprise most Member States of the European Union, as they underestimated the rapid spread of the contagion in the continent. The response of the Member States was asymmetrical, individualistic and significantly slow. The first measures taken were to close down the internal borders. The response of the European Union was even slower to the point that and it was not until March 17th 2020 that the external borders were closed. These actions affected legal migration into the European Union from four perspectives: 1) it affected the mobility of those third country nationals who were on temporary stay in the Member States; 2) the entry of third country nationals to do seasonal work; 3) the entry and stay of legal migrants; and 4) the status quo of the third country nationals already residing in the Member States, especially those who have a loss of income. This article will deal with the measures taken by Member States on who to manage the immigration services during the crisis as well as the measures taken in order to deal with overstayers, seasonal workers and other legal migrants. Finally, we will focus in the vulnerable situation that third-country national salaried workers are exposed due to the loss of income or loss of employment in the Member States and the risk of being returned to their country of origin.

The accelerated digitalisation of society along with technological evolution have extended the geographical span of cyber-physical systems. Two main threats have made the reliable and real-time control of these systems challenging: (i) uncertainty in the communication infrastructure induced by scale, openness and heterogeneity of the environment and devices; and (ii) targeted attacks maliciously worsening the impact of the above-mentioned communication uncertainties, disrupting the correctness of real-time applications. This paper addresses those challenges by showing how to build distributed protocols that provide both real-time with practical performance, and scalability in the presence of network faults and attacks. We provide a suite of real-time Byzantine protocols, which we prove correct, starting from a reliable broadcast protocol, called PISTIS, up to atomic broadcast and consensus. This suite simplifies the construction of powerful distributed and decentralized monitoring and control applications, including state-machine replication. Extensive empirical evaluations show- case PISTIS’s robustness, latency, and scalability. For example, PISTIS can withstand message loss (and delay) rates up to 40% in systems with 49 nodes and provides bounded delivery latencies in the order of a few milliseconds. [less ▲]

Over three years have passed since 29 March 2017, the date when the United Kingdom (UK) triggered Article 50 of the Treaty on European Union (TEU). This date has become well-known, for paving the way to multiple legal issues, which mostly depend on the finalisation of an agreement setting the conditions for the future relations between the European Union (EU) and the UK. Despite recent political declarations, the Brexit outcome is now clear, and a transitional period has just begun. As a result, for the resolution of credit institutions established in the EU, the bail-in of liabilities previously established under English law could become problematic. To date, the EU framework for the resolution of credit institutions (namely, the Bank Recovery and Resolution Directive – BRRD) lacks a provision for the direct recognition of liabilities governed under third-country law. However, through its Article 55, the BRRD leaves to the EU Member State (MS) the duty to require entities to include “resolution-proof” clauses or, alternatively, to conclude a binding agreement with the relevant third country. This leaves a legislative gap concerning this direct recognition. By analysing the current EU legal framework for the bail-in of liabilities established with contracts governed by third-country law, with a view to identify its weaknesses, this paper aims at addressing possible practical solutions. The purpose is to ease the resolution process for the relevant administrative authority of the EU MS in charge of the resolution procedure, without the need of an immediate intervention of the legislator. Indeed, a solution for such gap in the BRRD might be disentangled outside the Brexit withdrawal agreement, or with specific arrangements between the EU/EU MS and the UK administrative authorities.

We prove using an integral criterion the existence and completeness of the wave operators corresponding to the Hodge-Laplacians acting on differential p-forms, induced by two quasi-isometric Riemannian metrics g and h on a complete open smooth manifold M. In particular, this result provides a criterion for the absolutely continuous spectra to coincide. The proof is based on gradient estimates obtained by probabilistic Bismut-type formulae for the heat semigroup defined by spectral calculus. By these localised formulae, the integral criterion only requires local curvature bounds and some upper local control on the heat kernel acting on functions, but no control on the injectivity radii. A consequence is a stability result of the absolutely continuous spectrum under a Ricci flow. As an application we concentrate on the important case of conformal perturbations. [less ▲]

"Everything was booked and ready to go for a two-day scientific workshop on education policies in Europe, scheduled for April 23-24, 2020 at the Hertie School in Berlin. The workshop intended to take stock of developments at the European, national and sub-national levels given the European Union’s wrap up of its decade-long Education & Training 2020 strategy (ET 2020), a framework for cooperation in education and training. However, on March 12, we had to cancel the physical meeting on short notice due to the coronavirus crisis. In the following, we share our experiences with the subsequent transition to an alternative online workshop format that took place on April 23, involving 25 participants from 10 countries, and 16 paper presentations. After sketching the workshop’s virtual setup, we discuss strengths, weaknesses, and challenges related to this digital transition. Furthermore, we explore the prospects of such online formats for future academic conferences and networking." [less ▲]

We define a model of international trade with two countries, two vertically differentiated goods, and heterogenous consumers concerning their willingness to pay for quality. Trade generates two sources of pollution: the production of domestic and traded goods, and their transportation between countries. Consumers in both countries manifest home bias which translates into ethnocentric preferences: (i) consumer perceive the quality of the domestic good amplified; and (ii) consumers thrive additional satisfaction when consuming a domestic good rather than a foreign one since only the former can satisfy their sense of place. By contrast, they suffer a psychological penalty when consuming a foreign product. We investigate the role of trade costs and ethnocentric attitude in shaping the equilibrium configuration of the international duopoly. Finally, we uncover the environmental damage from production and from transport in presence of ethnocentrism. [less ▲]

Let λ− and λ+ be two bounded measured laminations on the hyperbolic disk H2, which "strongly fill" (definition below). We consider the left earthquakes along λ− and λ+, considered as maps from the universal Teichmüller space T to itself, and we prove that the composition of those left earthquakes has a fixed point. The proof uses anti-de Sitter geometry. Given a quasi-symmetric homeomorphism u:RP1→RP1, the boundary of the convex hull in AdS3 of its graph in RP1×RP1≃∂AdS3 is the disjoint union of two embedded copies of the hyperbolic plane, pleated along measured geodesic laminations. Our main result is that any pair of bounded measured laminations that "strongly fill" can be obtained in this manner. [less ▲]

The present study examined the dimensionality and the measurement invariance of the Multicultural Ideology Scale (MCI; Berry & Kalin, 1995), and mean differences across different cultural groups within the multilingual, multicultural context of Luxembourg. With 47% of the citizens being non-nationals, minority and majority are increasingly difficult to define and Luxembourg becomes a unique context to study attitudes towards diversity. Our sample included 1488 participants from diverse ethnic backgrounds who completed the survey in German, French or English. In contrast to previous findings, our analyses revealed a two-dimensional structure, distinguishing between positive and negative attitudes towards multiculturalism. The factor structure was partially invariant across ethnocultural groups: Configural and metric invariance were established across natives and non-natives, scalar invariance only across gender groups. Natives and male participants reported more negative attitudes towards multiculturalism. We discuss the importance of assessing measurement invariance and provide recommendations to improve the assessment of psychological multiculturalism. [less ▲]

Contact tracing is an important instrument for national health services to fight epidemics. As part of the COVID-19 situation, many proposals have been made for scaling up contract tracing capacities with the help of smartphone applications, an important but highly critical endeavor due to the privacy risks involved in such solutions. Extending our previously expressed concern, we clearly articulate in this article, the functional and non-functional requirements that any solution has to meet, when striving to serve, not mere collections of individuals, but the whole of a nation, as required in face of such potentially dangerous epidemics. We present a critical information infrastructure, PriLock, a fully-open preliminary architecture proposal and design draft for privacy preserving contact tracing, which we believe can be constructed in a way to fulfill the former requirements. Our architecture leverages the existing regulated mobile communication infrastructure and builds upon the concept of "checks and balances", requiring a majority of independent players to agree to effect any operation on it, thus preventing abuse of the highly sensitive information that must be collected and processed for efficient contact tracing. This is enforced with a largely decentralised layout and highly resilient state-of-the-art technology, which we explain in the paper, finishing by giving a security, dependability and resilience analysis, showing how it meets the defined requirements, even while the infrastructure is under attack.

Today, leveraging the enormous modular power, diversity and flexibility of manycore systems-on-a-chip (SoCs) requires careful orchestration of complex resources, a task left to low-level software, e.g. hypervisors. In current architectures, this software forms a single point of failure and worthwhile target for attacks: once compromised, adversaries gain access to all information and full control over the platform and the environment it controls. This paper proposes Midir, an enhanced manycore architecture, effecting a paradigm shift from SoCs to distributed SoCs. Midir changes the way platform resources are controlled, by retrofitting tile-based fault containment through well known mechanisms, while securing low-overhead quorum-based consensus on all critical operations, in particular privilege management and, thus, management of containment domains. Allowing versatile redundancy management, Midir promotes resilience for all software levels, including at low level. We explain this architecture, its associated algorithms and hardware mechanisms and show, for the example of a Byzantine fault tolerant microhypervisor, that it outperforms the highly efficient MinBFT by one order of magnitude.

Research suggests that systematic tail risk affects the cross-sectional variation in hedge fund returns. Fund’s tail risk is mainly induced by its investments in more tail-sensitive stocks and is positively related to a trading strategy of writing out-of-the-money put options on the equity market index. Hence, high tail risk hedge funds are exposed to higher moments risks; they sell market volatility risk and buy market skewness risk. The relationship between the return spread of a high minus low tail risk strategy and a market volatility factor is expected to be negative and empirically observed to be negative. However, the relationship between a tail risk strategy and a market skewness factor is expected to be positive but I find it to be negative. In this paper, I explore this puzzling result. Using equity-oriented hedge fund return data, I find that equity market skewness risk explains a major part of variations in hedge funds’ tail risk. My results suggest that the observed negative relationship relates to the problem of price pressure associated with “crowded trades” of mutual funds. Given that retail investors are prone to herding, the directional trading of mutual funds is correlated, and their collective actions can generate short-term price pressure on aggregate stock prices (price ‘noise’). Short sellers systematically exploit these patterns not only in the equity lending market, but also in the options market by moving in the opposite direction. Hence, in times when investors shift their funds from bond to equity mutual funds, short selling in the options market, the non-fundamental demand for index put options, induces a negative relationship between risk-neutral market skewness and returns. Accordingly, the long leg of the tail risk strategy appears to be negatively exposed to market skewness risk, which is in contrast to the usual interpretation of option-implied skewness as an indicator of jump risk. My results are in line with empirical evidence that suggests that the shape of the implied volatility curve is attributable to the demand pressure of specific option series and a limited ability of arbitrageurs to bring prices back into alignment.

I evaluate Christine Lagarde´s claim that more female leaders can be associated with more prudence, and less of the risky decision-making that had provoked the crisis. Indeed, the proportion of women who are employed in decision-making and management roles in governments, large enterprises and institutions varies substantially across European countries and is oftentimes below 30%. Research suggests that in addition to biological differences, men and women show morphological dissimilarities in specific brain regions, which explain the observed differences in behavior. As a result, female decision makers tend to be more risk averse, better suited to carefully analyze a problem, superior in multitasking and better in creating solutions that work for a group. Not surprisingly, firms with more female decision makers tend to outperform their peers in terms of productivity, profitability and stock performance while taking fewer risks. In this paper, I aim to explore the effect of female decision making on aggregate equity returns. Relying on an equilibrium asset-pricing model in an economy under jump diffusion, I decompose the moments of the returns of European stock market indices into a diffusive (systematic) risk and an (idiosyncratic) extreme event risk part. For a balanced panel of European countries, I find empirical evidence for a Lehman sisters’ effect: female decision making is an important determinant of (idiosyncratic) extreme event risk. As a result, stock markets in countries with more female decision makers are characterized by higher risk aversion, lower volatility and more positive return asymmetry, primarily driven by extreme event risk, e.g. the lower frequency of negative jumps. Results are robust to the inclusion of various controls for other country- or market-specific characteristics. [less ▲]

L'objectif de cette boîte à outils de soutien est d'être mis en œuvre principalement au niveau des cours réguliers d'éducation physique pour aider les enseignants d’éducation physique à adapter leurs contenus et leurs méthodes d'enseignement. La boîte à outils pour la formation des enseignants présente les éléments à mettre en œuvre lors de formations d'enseignants. Celles-ci sont structurées en une partie théorique et une partie pratique. Dans un premier temps, les enseignants sont familiarisés avec le concept MOBAK, la mesure, la procédure de test, le traitement des données et l’évaluation ainsi qu'avec l'interprétation des résultats du test. Dans une deuxième partie, ils apprennent à passer du diagnostic des compétences motrices de base des élèves et des forces et faiblesses identifiées dans l'évaluation à des interventions concrètes en utilisant le cadre de soutien MOBAK et les documents qui l'accompagnent sous la forme d'un support théorique (boîte à outils pour l’enseignant), prêt à être mis en œuvre dans des situations éducatives concrètes pour soutenir les élèves ayant des besoins supplémentaires en compétences motrices de base. Étant donné que la boîte à outils pour la formation des enseignants vise à soutenir et à faciliter la mise en œuvre de la formation théorique des enseignants de soutien modulaire pour les enseignants (Scheuer et Heck, 2020), il sera fait référence au concept et au construit des tests MOBAK (Herrmann, 2018), et au manuel de test MOBAK tout au long de ce document.

Im Rahmen des BMC-EU Projekts (Basic Motor Competencies in Europe) wurde ein Toolkit für die Fortbildung von Sportlehrkräften entwickelt, welches aus einem Fortbildungskonzept inklusive eines Handbuchs (BMC-EU intellectual output 4) besteht. Die Entwicklung dieses Fortbildungskonzepts soll dazu beitragen, dass das modulare Support Toolkit auf der Basis des Konzepts der motorischen Basiskompetenzen (BMC-EU intellectual output 3; Scheuer & Heck, 2020) eingesetzt wird. Das Ziel dieses Support Toolkits ist hauptsächlich der Einsatz auf der Ebene des regulären Sportunterrichts um die Anpassungen, welche den Inhalt und die Methoden des Unterrichtens betreffen, voranzutreiben. Das Toolkit für die Fortbildung von Lehrkräften beinhaltet Materialen, die für die Durchführung einer strukturierten Lehrerfortbildung sowohl im theoretischen als auch im praktischen Teil benötigt werden. Im ersten Schritt werden die Lehrkräfte mit dem MOBAK Konzept, der Datenerhebung, der Testdurchführung, der Datenverarbeitung und –evaluation sowie mit der Interpretation der Testergebnisse vertraut gemacht. Im zweiten Schritt lernen die Lehrkräfte wie sie auf die Stärken und Schwächen ihrer Schülerinnen und Schüler, welche die Ergebnisse aus den Tests zu den motorischen Basiskompetenzen zeigen, fördern können, indem sie das MOBAK Support Toolkit verwenden. Dieses Toolkit kann direkt in konkrete Unterrichtsszenarien eingesetzt werden, um die Schülerinnen und Schüler mit zusätzlichem Förderbedarf in den motorischen Kompetenzen zu unterstützen. Da das Toolkit für die Fortbildung von Lehrkräfte darauf abzielt, die Durchführung des modularen Support Toolkits für Lehrkräfte (Scheuer & Heck, 2020) basierend auf dem MOBAK Konzept (Herrmann, 2018) zu unterstützen und zu ermöglichen, wird in diesem Dokument immer wieder auf das Support Toolkit und das MOBAK Testmanual verwiesen.

Nell’ambito del progetto BMC-EU (Competenze motorie di base in Europa), è stato sviluppato un ulteriore documento utile alla formazione degli insegnanti, che consiste in un manuale di formazione (output intellettuale BMC-EU 4), al fine di implementare il manuale modulare riguardante le competenze motorie di base (produzione intellettuale BMC-EU 3; Scheuer & Heck, 2020). Lo scopo di questo manuale è quello di ampliare i contenuti delle lezioni curriculari di educazione fisica, per proporre gli adattamenti riguardanti le attività ed i metodi. Il manuale contiene i materiali per implementare il processo di formazione degli insegnanti ed è strutturato in una parte teorica e una pratica. In una prima parte, gli insegnanti acquisiscono familiarità con la struttura del MOBAK, la misurazione, l’attuazione delle prove, l’elaborazione e e la valutazione dei dati, nonché con l'interpretazione dei risultati delle prove. In una seconda parte, imparano ad acquisire informazioni sulle competenze motorie di base degli allievi e sui punti di forza e di debolezza identificati nella valutazione. Inoltre, mediante proposte operative presenti nel manuale modulare del MOBAK e negli allegati, è possibile implementare i contesti di apprendimento per sostenere gli allievi con bisogni educativi speciali nelle competenze motorie di base. Il presente manuale per la formazione degli insegnanti è finalizzato a sostenere ed integrare il manuale modulare (Scheuer & Heck, 2020), basato sulla struttura e sui livelli del MOBAK (Herrmann, 2018).

Στο πλαίσιο του έργου BMC-EU (Βασικές Κινητικές Δεξιότητες στην Ευρώπη), αναπτύχθηκε μία εργαλειοθήκη κατάρτισης για εκπαιδευτικούς, αποτελούμενη από τη γενική πρακτική ιδέα και ένα συνοδευτικό εγχειρίδιο χρήστη (BMC-EU πνευματική παραγωγή 4), για να υποστηρίξει την εφαρμογή της υποστηρικτικής εργαλειοθήκης με βάση την έννοια των βασικών κινητικών δεξιοτήτων (BMC-EU πνευματική παραγωγή 3; Scheuer & Heck, 2020). Ο σκοπός της εργαλειοθήκης αυτής είναι να εφαρμοστεί στα μαθήματα φυσικής αγωγής, ώστε να προσαρμοστούν κατάλληλα τόσο το περιεχόμενο όσο και οι μέθοδοι διδασκαλίας της φυσικής αγωγής. Η εργαλειοθήκη κατάρτισης για εκπαιδευτικούς περιέχει υλικό για τη δημιουργία πρακτικών προγραμμάτων για εκπαιδευτικούς δομημένα τόσο σε θεωρητικό, όσο και πρακτικό επίπεδο. Αρχικά, οι εκπαιδευτικοί εξοικειώνονται με την έννοια του ΜΟΒΑΚ, τις μετρήσεις, τη διαδικασία της εξέτασης, την επεξεργασία των δεδομένων και την αξιολόγηση, καθώς και με την ερμηνεία των αποτελεσμάτων. Στη συνέχεια, μαθαίνουν πώς να μεταβούν από τη διάγνωση των βασικών κινητικών δεξιοτήτων και τον εντοπισμό των αντίστοιχων ικανοτήτων των μαθητών, στον σχεδιασμό και την υλοποίηση συγκεκριμένων παρεμβάσεων με τη χρήση του υποστηρικτικού πλαισίου ΜΟΒΑΚ και των συνοδευτικών υποστηρικτικών φυλλαδίων, που είναι έτοιμα προς εφαρμογή σε συγκεκριμένες εκπαιδευτικές συνθήκες για την υποστήριξη μαθητών με πρόσθετες ανάγκες στις βασικές κινητικές δεξιότητες. Η εργαλειοθήκη κατάρτισης για εκπαιδευτικούς έχει ως σκοπό να υποστηρίξει και να διευκολύνει την εφαρμογή της Υποστηρικτικής εργαλειοθήκης για εκπαιδευτικούς (Scheuer & Heck, 2020), που βασίζεται στην έννοια και τις μετρήσεις ΜΟΒΑΚ (Herrmann, 2018).

In the frame of the BMC-EU project (Basic motor competencies in Europe), a teacher training toolkit consisting of a teacher training concept with an accompanying user manual (BMC-EU intellectual output 4) was developed in order to support the implementation of the modular support toolkit on the basis of the concept of basic motor competences (BMC-EU intellectual output 3; Scheuer & Heck, 2020). The aim of this support toolkit is to be implemented mainly at the level of regular physical education lessons to initiate adaptations regarding the content and methods in physical education instruction. The teacher training toolkit contains materials to implement teacher trainings structured in a theoretical and a practical part. In a first step, teachers are familiarized with the MOBAK concept, measurement, test procedure, data procession and evaluation as well as with the interpretation of test results. In a second part, they learn how to get from the diagnosis of the students’ basic motor competencies and the strengths and weaknesses identified in the assessment to concrete interventions by using the MOBAK support framework and the accompanying supportive handouts in form of a modular support toolkit, ready to be implemented in concrete educational situations to support students with additional needs in basic motor competencies. As the teacher training toolkit aims to support and facilitate the implementation of the Modular support toolkit for teachers (Scheuer & Heck, 2020) based on the MOBAK concept and measurement (Herrmann, 2018), reference to the support toolkit and the MOBAK Test manual is given throughout this document [less ▲]

Patient-derived cancer models are essential tools for studying tumor biology and preclinical interventions. Here, we show that glioma patient-derived orthotopic xenografts (PDOXs) enable long-term propagation of patient tumors and represent clinically relevant patient avatars. We created a large collection of PDOXs from primary and recurrent gliomas with and without mutations in IDH1, which retained histopathological, genetic, epigenetic and transcriptomic features of patient tumors with no mouse-specific clonal evolution. Longitudinal PDOX models recapitulate the limited genetic evolution of gliomas observed in patient tumors following treatment. PDOX-derived standardized tumor organoid cultures enabled assessment of drug responses, which were validated in mice. PDOXs showed clinically relevant responses to Temozolomide and to targeted treatments such as EGFR and CDK4/6 inhibitors in (epi)genetically defined groups, according to MGMT promoter and EGFR/CDK status respectively. Dianhydrogalactitol, a bifunctional alkylating agent, showed promising potential against glioblastoma. Our study underlines the clinical relevance of glioma PDOX models for translational research and personalized treatment studies. [less ▲]

Previous research suggests that the cross-section of stock returns has substantial exposure to risks captured by higher moments in market returns. In particular, the market skewness risk premium is negative, statistically and economically significant, and cannot be explained by other common risk factors or firm characteristics. This is somewhat counterintuitive when one considers the usual interpretation of e.g. option-implied skewness as an indicator of jump risk or downside risk in the stock market. I find that price pressure associated with “crowded trades” of mutual funds is partly explaining the observed negative price of market skewness risk. Given that retail investors are prone to herding, the directional trading of mutual funds is correlated, and their collective actions can generate short-term price pressure on aggregate stock prices. Short sellers systematically exploit these patterns not only in the equity lending market, but also in the options market by moving in the opposite direction. Therefore, during flight-to-risk (FTR) episodes, when equity funds experience inflows and market prices are contaminated by ‘noise’, negative shifts in market skewness are due to short selling and do not necessarily reflect market participants’ fear about increased downside risk in the stock market. Therefore, stocks with a negative past skewness exposure perform well, because they positively correlate with the ‘noise’ component. As a result, while the expected market skewness risk premium is positive, the observed one is on average negative. I find that, firstly, net exchanges of equity funds are affecting the cross-section of stock returns, leading to a significant negative market skewness risk premium. Secondly, while the volatility risk premium appears to vary over time, the skewness risk premium is found to be constant. Thirdly, in line with my hypothesis, the market skewness risk premium is only significantly negative in months when retail investors transfer their money from bond funds to equity funds. Various robustness checks confirm the validity of the results. My findings also suggest that price ‘noise’ induced by uninformed trading is not vanished at the aggregate level. [less ▲]

In the frame of the BMC-EU project (Basic motor competencies in Europe), a support framework and a modular support toolkit on the basis of the concept of basic motor competences and the results of the data collection in phase 1 of the project was developed as part of intellectual output 3. The aim of this toolkit is to be implemented mainly at the level of regular physical education lessons to initiate adaptations regarding the content and methods in physical education instruction. In a first step, the support framework was developed for getting from the diagnosis of the students’ basic motor competencies and the strengths and weaknesses identified in the assessment to concrete interventions. Based on this framework, supportive handouts in form of a modular support toolkit were developed, ready to be implemented in concrete educational situations to support students with additional needs in basic motor competencies. The modular support toolkit includes guidelines for the interpretation of MOBAK (Motorische Basiskompetenzen; German for basic motor competencies) test results, the MOBAK support framework, a glossary, as well as the modular support toolkit with materials for physical education teachers in the form of MOBAK task description cards and MOBAK activity cards based on principles of variation and on a competence-oriented approach.

Bitcoin is the oldest and most widely established cryptocurrency network with the highest market capitalization among all cryptocurrencies. Although bitcoin (with lowercase b) is increasingly viewed as a digital asset belonging to a new asset class, the Bitcoin network (with uppercase B) is a decentralized financial market infrastructure (dFMI) that clears and settles transactions in its native asset without relying on the conventional financial market infrastructures (FMIs). To be a reliable asset class as well as a dFMI, however, Bitcoin needs to have robust governance arrangements; whether such arrangements are built into the protocol (i.e., on-chain governance mechanisms) or relegated to the participants in the Bitcoin network (i.e., off-chain governance mechanisms), or are composed of a combination of both mechanisms (i.e., a hybrid form of governance). This paper studies Bitcoin governance with a focus on its alleged shortcomings. In so doing, after defining Bitcoin governance and its objectives, the paper puts forward an idiosyncratic governance model whose main objective is to preserve and maximize the main value proposition of Bitcoin, i.e., its censorship-resistant property, which allows participants to transact in an environment with minimum social trust. Therefore, Bitcoin governance, including the processes through which Bitcoin governance crises have been resolved and the standards against which the Bitcoin Improvement Proposals (BIPs) are examined, should be analyzed in light of the prevailing narrative of Bitcoin as a censorship-resistant store of value and payment infrastructure. Within such a special governance model, this paper seeks to identify the potential shortcomings in Bitcoin governance by reference to the major governance crises that posed serious threats to Bitcoin in the last decade. It concludes that the existing governance arrangements in the Bitcoin network have been largely successful in dealing with Bitcoin’s major crises that would have otherwise become existential threats to the Bitcoin network.

We investigate the terms arising in an identity for hyperbolic surfaces proved by Luo and Tan, namely showing that they vary monotonically in terms of lengths and that they verify certain convexity properties. Using these properties, we deduce two results. As a first application, we show how to deduce a theorem of Thurston which states, in particular for closed hyperbolic surfaces, that if a simple length spectrum "dominates" another, then in fact the two surfaces are isometric. As a second application, we show how to find upper bounds on the number of pairs of pants of bounded length that only depend on the boundary length and the topology of the surface. [less ▲]

In this paper, we explore the fiscal impact of immigrants in Europe applying a quantile regression approach to data from the European Survey on Living Conditions (EU-SILC) for the period 2007-2015. Our estimations show that not only on average but also in almost all income quantiles, the fiscal position of both European and non-European migrants is not significantly different from that of native citizens. Furthermore, non-EU migrants are net contributors as compared to the corresponding native citizens in the Netherlands and Belgium for various quantiles. Lastly, we examine the link between migrants’ fiscal position and the fiscal perception of native European citizens measured using ESS data. We find a conflicting relationship: countries where migrants are perceived negatively are instead countries where they are net fiscal contributors and vice versa. [less ▲]

In this article, exponential contraction in Wasserstein distance for heat semigroups of diffusion processes on Riemannian manifolds is established under curvature conditions where Ricci curvature is not necessarily required to be non-negative. Compared to the results of Wang (2016), we focus on explicit estimates for the exponential contraction rate. Moreover, we show that our results extend to manifolds evolving under a geometric flow. As application, for the time-inhomogeneous semigroups, we obtain a gradient estimate with an exponential contraction rate under weak curvature conditions, as well as uniqueness of the corresponding evolution system of measures.

In this note, we report several solutions to the STARK-Friendly Hash Challenge: a competition with the goal of finding collisions for several hash functions designed specifically for zero-knowledge proofs (ZKP) and multiparty computations (MPC). We managed to find collisions for 3 instances of 91-bit hash functions. The method used is the classic parallel collision search with distinguished points from van Oorshot and Wiener (1994). As this is a general attack on hash functions, it does not exhibit any particular weakness of the chosen hash functions. The crucial part is to optimize the implementations to make the attack cost realistic, and we describe several arithmetic tricks. [less ▲]

Even though the Paris Agreement posits the need to align overall financial flows with low-carbon and climate-resilient development in the heart of its objectives, developing countries face ample constraints in mitigating and adapting to climate change, while concomitantly embarking on reconciling the curbing of climate change with development concerns. Climate finance constitutes an enabling means not only for assisting developing countries in building capacities and enabling environments to address climate change in compliance with their commitments under the Paris Agreement, but most importantly for ushering a long-term development shift towards sustainability. This article furthers the discourse on what it means to be ‘legally ready’ for climate finance. It argues that legal reforms present a means to overcome legal barriers undermining climate finance effectiveness in developing countries, aimed at mainstreaming climate change considerations across all sectors and national policies, stimulating climate-related flows from all sources of finance, and instituting a paradigm shift towards climate-resilient development. First, it elaborates on the role of law in building climate finance readiness, the key legal barriers encountered in developing countries, and the main legal approaches and regulatory tools likely to enhance the four main capacities required to be ready for climate finance. Second, it illustrates the laws and policies currently implemented in Bangladesh concerning the country’s readiness for climate finance. The article concludes premised on the case study of Bangladesh that legal reforms are essential in developing countries, in order to ensure long-term climate finance effectiveness steering transformative changes.

The current COVID-19 outbreak represents a most serious challenge for societies worldwide. It isendangering the health of millions of people, and resulting in severe socioeconomic challenges dueto lock-down measures. Governments worldwide aim to devise exit strategies to revive the economywhile keeping the pandemic under control. The problem is that the effects of distinct measures arenot well quantified. This paper compares several suppression approaches and potential exit strategiesusing a new extended epidemic SEIR model. It concludes that while rapid and strong lock-down isan effective pandemic suppression measure, a combination of other strategies such as social distanc-ing, active protection and removal can achieve similar suppression synergistically. This quantitativeunderstanding will support the establishment of mid- and long-term interventions. Finally, the paperprovides an online tool that allows researchers and decision makers to interactively simulate diversescenarios with our model. [less ▲]

We study the class of symmetric $n$-ary bands. These are $n$-ary semigroups $(X,F)$ such that $F$ is invariant under the action of permutations and idempotent, i.e., satisfies $F(x,\ldots,x)=x$ for all $x\in X$. We first provide a structure theorem for these symmetric $n$-ary bands that extends the classical (strong) semilattice decomposition of certain classes of bands. We introduce the concept of strong $n$-ary semilattice of $n$-ary semigroups and we show that the symmetric $n$-ary bands are exactly the strong $n$-ary semilattices of $n$-ary extensions of Abelian groups whose exponents divide $n-1$. Finally, we use the structure theorem to obtain necessary and sufficient conditions for a symmetric $n$-ary band to be reducible to a semigroup. [less ▲]

With stunning green landscapes, exemplary public transport, and picturesque walkable cities, Switzerland often occupies the public imaginary of a place that has tackled sustainable development. This research, however, looks under the hood and finds that this development path supports not only modes of capital accumulation, but also certain less sustainable patterns of development and governance. This paper examines this apparent paradox by looking at the role of sustainable development as a master-signifier in Swiss urban development processes. Empirical observations were made in the Glatt Valley of Switzerland, where governing officials of small municipalities are confronted with coordinating urban development under growth pressure within cantonal and federal policy frameworks that claim sustainable development. It can be seen that sustainable development is an empty master-signifier that policy makers engage to justify the quilting of a certain hegemonic discourses of power that reflect in further uneven urban development. By reproducing business as usual market-led urban growth, fragmentation is maintained as are social spatial disparities are entrenched. [less ▲]

We also study the primes p for which the index of \alpha_i mod p is a fixed integer or lies in a given set of integers for each i. An additional condition on the Frobenius conjugacy class of p may be considered. Such results are generalizations of a theorem of Ziegler from 2006, which concerns the case r=1 of this problem.

In this paper, we analyze theoretically and empirically the effects of tax changes on firms’ profits in extractive industries. In the theoretical part, we assume a country that levies a profit tax and a royalty on the profits of extractive firms to maximize its tax revenues. The mining companies may reduce their taxable income by cost manipulation. By analyzing the optimal choice of the government and of the firms, we first establish the optimal tax policy and then we investigate the impact of the optimal fiscal policy on firms’ profits. In the empirical part of the paper, we estimate the effect of the profit tax and royalty on the extracting firms’ profit in African countries during the period spanning from 2007 to 2018. We use the Mining Intelligence database to constitute a panel of annual individual data from a database of 363 gold mines located in 21 Sub-Saharan countries. We obtain an inverse relationship between the tax rate change of the two tax instruments and the profit of the firms. [less ▲]

National parliaments tend to delegate a range of tasks related to EU affairs scrutiny to their administrations. However, there is considerable variation in the extent to which national parliaments invest in EU affairs staff. This raises two questions: what is the source of this diversity, and what is its impact on the EU affairs scrutiny of national parliaments? This paper argues that greater investments in EU affairs staff are associated with public Euroscepticism, large parliaments and parliaments with strong scrutiny powers. A large EU staff is, in turn, associated with parliaments that are relatively active in EU affairs scrutiny. This is particularly true for the 15 EU member states that joined before 2004. [less ▲]

Topologically protected qubits based on nanostructures hosting Majorana bound states (MBSs) hold great promise for fault-tolerant quantum computing. We study the transport properties of nanowire networks hosting MBSs with a focus on the effects of the charging energy and the overlap between neighboring MBSs in short mesoscopic samples. In particular, we investigate structures hosting four MBSs such as T-junctions and Majorana boxes. Using a master equation in the Markovian approximation, we discuss the leading transport processes mediated by the MBSs. Single-electron tunneling and processes involving creation and annihilation of Cooper pairs dominate in the sequential tunneling limit. In the cotunneling regime the charge in the MBSs network is fixed and transport is governed by transitions via virtual intermediate states. Our results show that four-terminal measurements in the T-junction and Majorana box geometries can be useful tools for the characterization of the properties of MBSs with finite overlaps and charging energy.

The aim of this article is to analyse the 2019 European election in Luxembourg and to contextualize it by comparing it with past elections. The article presents the party landscape, the electoral campaign, the electoral system and the results of the 2019 European election. The results are then analysed in the context of past national and European elections in order to establish whether European elections are second-order elections in Luxembourg, how electoral volatility evolved over time, whether there is a rise in Eurosceptic parties and how the representation of women has evolved since 1979.

We study the geometry of the foliation by constant Gaussian curvature surfaces (S_k)_k of a hyperbolic end, and how it relates to the structures of its boundary at infinity and of its pleated boundary. First, we show that the Thurston and the Schwarzian parametrizations are the limits of two families of parametrizations of the space of hyperbolic ends, defined by Labourie in 1992 in terms of the geometry of the leaves S_k. We give a new description of the renormalized volume using the constant curvature foliation. We prove a generalization of McMullen's Kleinian reciprocity theorem, which replaces the role of the Schwarzian parametrization with Labourie's parametrizations. Finally, we describe the constant curvature foliation of a hyperbolic end as the integral curve of a time-dependent Hamiltonian vector field on the cotangent space to Teichmüller space, in analogy to the Moncrief flow for constant mean curvature foliations in Lorenzian space-times.

It is no exaggeration to say that since the introduction of Bitcoin, blockchains have become a disruptive technology that has shaken the world. However, the rising popularity of the paradigm has led to a flurry of proposals addressing variations and/or trying to solve problems stemming from the initial specification. This added considerable complexity to the current blockchain ecosystems, amplified by the absence of detail in many accompanying blockchain whitepapers. Through this paper, we set out to explain blockchains in a simple way, taming that complexity through the deconstruction of the blockchain into three simple, critical components common to all known systems: membership selection, consensus mechanism and structure. We propose an evaluation framework with insight into system models, desired properties and analysis criteria, using the decoupled components as criteria. We use this framework to provide clear and intuitive overviews of the design principles behind the analyzed systems and the properties achieved. We hope our effort will help clarifying the current state of blockchain proposals and provide directions to the analysis of future proposals. [less ▲]
