La crise sanitaire provoquée par la pandémie de COVID-19 a imposé d’importantes adaptations au marché du travail transfrontalier dans la Grande Région SaarLorLux. Les mesures prises pour éviter la propagation de la maladie imposent de limiter les déplacements au strict minimum tandis que l’efficience des services de santé publics impose la proximité. Ces mesures, qui se sont rapidement imposées aux acteurs publics, aux entreprises et aux individus, questionnent directement le fonctionnement d’un marché du travail transfrontalier structuré par la mobilité transfrontalière. Afin de maintenir tant que possible les activités économiques et de pourvoir aux besoins sanitaires, les exécutifs nationaux ont adapté les fonctions de la frontière. [less ▲]

Coding and non-coding RNAs have diagnostic and prognostic importance in Parkinson’s diseases (PD). We studied circulating small non-coding RNAs (sncRNAs) in 7, 003 samples from two longitudinal PD cohorts (Parkinson’s Progression Marker Initiative (PPMI) and Luxembourg Parkinson’s Study (NCER-PD)) and modelled their influence on the transcriptome. First, we sequenced sncRNAs in 5, 450 blood samples of 1, 614 individuals in PPMI. The majority of 323 billion reads (59 million reads per sample) mapped to miRNAs. Other covered RNA classes include piRNAs, rRNAs, snoRNAs, tRNAs, scaRNAs, and snRNAs. De-regulated miRNAs were associated with the disease and disease progression and occur in two distinct waves in the third and seventh decade of live. Originating mostly from a characteristic set of immune cells they resemble a systemic inflammation response and mitochondrial dysfunction, two hallmarks of PD. By profiling 1, 553 samples from 1, 024 individuals in the NCER-PD cohort using an independent technology, we validate relevant findings from the sequencing study. Finally, network analysis of sncRNAs and transcriptome sequencing of the original cohort identified regulatory modules emerging in progressing PD patients.Competing Interest StatementThe authors have declared no competing interest.

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 ▲]

BACKGROUND: After the World Health Organization declared the outbreak of coronavirus disease to be a public health emergency of international concern on January 30, 2020, the first SARS-CoV-2 infection was detected in Luxembourg on February 29, 2020. Representative population-based data, including asymptomatic individuals for assessing the viral spread and immune response were, however, lacking worldwide. METHODS: Using a panel-based method, we implemented a representative sample of the Luxembourgish population based on age, gender and residency for testing for SARS-CoV-2 infection and antibody status in order to define prevalence irrespective of clinical symptoms. Participants were contacted via email to fill an online questionnaire before biosampling at local laboratories. All participants provided information related to clinical symptoms, epidemiology, socioeconomic and psychological assessments and underwent biosampling, rRT-PCR testing and serology for SARS-CoV-2. RESULTS: We included a total of 1862 individuals in our representative sample of the general Luxembourgish population. Of these, 5 individuals had a current positive result for infection with SARS-CoV-2 based on rRT-PCR. Four of these individuals were oligosymptomatic and one was asymptomatic. Overall we found a positive IgG antibody status in 35 individuals (1.97%), of which 11 reported to be tested positive by rRT-PCR for SARS-CoV-2 previously and showed in addition their IgG positive status also a positive status for IgA. Our data indicate a prevalence of 0.3% for active SARS-CoV-2 infection and an infection rate of 2.15% in the Luxembourgish population between 18 and 79 years of age. CONCLUSIONS: Luxembourgish residents show a low rate of acute infections after 7 weeks of confinement and present with an antibody profile indicative of a more recent immune response to SARS-CoV-2. All infected individuals were oligo- or asymptomatic. Bi-weekly follow-up visits over the next 2 months will inform about the viral spread by a- and oligosymptomatic carriers and the individual changes in the immune profile.Competing Interest StatementThe authors have declared no competing interest.Clinical TrialNCT04379297Funding StatementThe CON-VINCE Study is funded by the Research Fund Luxembourg (FNR; CON-VINCE) and the André Losch Foundation (Luxembourg).Author DeclarationsAll relevant ethical guidelines have been followed; any necessary IRB and/or ethics committee approvals have been obtained and details of the IRB/oversight body are included in the manuscript.YesAll necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived.YesI understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov.

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.

Moments of crisis like the current one sparked by Covid-19, engage social, economic, cultural and political institutions of a society and stress-test their resourcefulness, while individual and collective food supplies become primary concerns. Where does even the wealthiest of EU member States stand when it comes to food sovereignty and specific vulnerabilities, what needs to change and which food policies are needed to facilitate a sustainable food system – both locally and internationally? Combining qualitative, empirical research methods to textual and statistical analysis, as well as transformative research, I focus on key areas of Luxembourg’s food system presenting challenges – specific ones and structural ones intertwined with issues in other countries – and discuss current and planned pathways of optimisation. I will start out with an analysis of agricultural and commercial specificities of a food system with low self-sufficiency rates, linked to meat and dairy specialisations, but also to market accessibility and market structure issues, leading to heavy imports. I will then shed light on pathways currently put into practice by the State, by economic actors, by educational actors and by social movements and coalitions of the willing, advocating ecological, ethical and qualitative production methods. Finally, I will show how the first Food Policy Council at national level that Luxembourg is currently founding is favoring a deliberate shift towards a multi-stakeholder-lead effective food policy.

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.

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 ▲]

Dans le cadre du projet BMC-EU (Compétences motrices de base en Europe), une boîte à outils pour la formation des enseignants reprenant le concept de formation ainsi qu’un manuel d'utilisation (BMC-EU production intellectuelle 4) a été développée afin de soutenir la mise en œuvre de la formation aux tests MOBAK (boîte à outils pour l’enseignant-support théorique) la base du concept de compétences motrices de base (BMC-EU production intellectuelle 3 ; Scheuer & Heck, 2020). 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.

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).

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.

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 ▲]

V rámci projektu BMC-EU (Základné pohybové kompetencie v Európe) bol vytvorený súbor nástrojov odbornej prípravy učiteľov pozostávajúci z koncepcie odbornej prípravy učiteľov so sprievodným návodom na použitie (intelektuálny výstup BMC-EU 4), s cieľom podporiť využitie podporného metodického materiálu na základe koncepcie základných pohybových kompetencií (intelektuálny výstup BMC-EU 3; Scheuer & Heck, 2020). Cieľom tohto podporného materiálu je iniciovať na úrovni pravidelných hodín telesnej a športovej výchovy úpravy týkajúce sa obsahu a metód výučby telesnej a športovej výchovy. Nástroj pre školenie učiteľov obsahuje materiály na realizáciu školení učiteľov štruktúrovaných v teoretickej a praktickej časti. V prvom kroku sú učitelia oboznámení s koncepciou MOBAK, meraním, testovacím postupom, spracovaním a vyhodnotením údajov, ako aj s interpretáciou výsledkov testov. V druhej časti sa naučia, ako získať informácie z diagnostiky základných pohybových kompetencií žiakov a ich silných a slabých stránok identifikovaných pri hodnotení. Tiež sa naučia pracovať s pomocou podporného rámca MOBAK a sprievodných podporných nástrojov vo forme podpornej metodickej príručky, pripravenej na implementáciu v konkrétnych vzdelávacích situáciách na podporu žiakov s ďalšími potrebami v základných pohybových kompetenciách. Keďže cieľom súboru nástrojov prípravy učiteľov je podporiť a uľahčiť implementáciu metodickej príručky pre učiteľov (Scheuer & Heck, 2020) založenej na koncepte a meraní MOBAK (Herrmann, 2018), odkaz na podpornú metodickú príručku MOBAK je uvedený v tomto dokumente.

In het kader van het BMC-EU project (Basismotorische competenties in Europa) heeft men op basis van het concept van basismotorische competenties (BMC-EU intellectuele output), een toolkit voor de training van docenten ontwikkeld met daarbij een bijbehorende gebruikershandleiding. Het doel van deze toolkit is voornamelijk om op het niveau van de reguliere lessen lichamelijke opvoeding aanpassingen te initiëren die van toepassing zijn op de inhoud en methoden in de lichamelijke opvoeding. De training voor docenten is opgedeeld in een praktisch en theoretisch deel. Allereerst worden leraren vertrouwd gemaakt met het MOBAK concept, de meting, testprocedure, de gegevensverwerking en evaluatie, evenals met de interpretatie van de testresultaten. In een tweede deel leren ze hoe ze van de diagnose van de basismotorische competenties van studenten en de sterke en zwakke punten die bij de beoordeling zijn geïdentificeerd, kunnen komen tot concrete interventies. Dit kan door het MOBAK kader en de bijbehorende hand-outs te gebruiken in de vorm van een modulaire ondersteunende toolkit. Deze toolkit kan ingezet worden in concrete onderwijssituaties om kinderen met aanvullende behoeften in basismotorische competenties te ondersteunen. Aangezien de training voor docenten de uitvoering van de toolkit voor de brede motorische ontwikkeling (Scheuer & Heck, 2020), gebaseerd op het MOBAK-concept en meting (Herrmann, 2018), wil ondersteunen en vergemakkelijken, wordt in dit document verwezen naar de ondersteunende toolkit en de MOBAK-testhandleiding.

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 ▲]

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.

As cities grow and spatially expand, agricultural land is converted into residential land. In many developing countries, especially in Sub-Saharan Africa, this process is accompanied by a change in land tenure, whereby plots held under traditional customary arrangements are sold to new urban residents, possibly with formal property rights. This paper studies joint land-use and land-tenure conversion in an urban economics model in which intermediaries purchase agricultural land from customary owners and attempt to transform it into residential plots with statutory property rights. The spatial equilibrium includes a mix of land uses and rights where statutory and non-statutory residential plots coexist with customary land that is mainly used for agriculture. Because customary ownership is subject to uncertainty (because of tenure insecurity), the conversion process includes a potential information asymmetry between customary owners and intermediaries. The analysis shows that a market failure may emerge whereby some customary owners prefer to continue farming their land rather than participate in the urban residential land market, which results in a city that is too small. Empirical analysis using Malian data validates the key features of the model captured by land price gradients, as well as the ranking and the variance of land prices, and is suggestive of the presence of information asymmetry.

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 ▲]

We approach the study of totally real immersions of smooth manifolds into holomorphic Riemannian space forms of constant sectional curvature -1. We introduce a notion of first and second fundamental form, we prove that they satisfy a similar version of the classic Gauss-Codazzi equations, and conversely that solutions of Gauss-Codazzi equations are immersion data of some equivariant map. This study has some interesting geometric consequences: 1) it provides a formalism to study immersions of surfaces into SL(2,C) and into the space of geodesics of H^3; 2) it generalizes the classical theory of immersions into non-zero curvature space forms, leading to a model for the transitioning of hypersurfaces among H^n, AdS^n, dS^n and S^n; 3) we prove that a holomorphic family of immersion data corresponds to a holomorphic family of immersions, providing an effective way to construct holomorphic maps into the SO(n,C)-character variety. In particular we will point out a simpler proof of the holomorphicity of the complex landslide; 4) we see how, under certain hypothesis, complex metrics on a surface (i.e. complex bilinear forms of its complexified tangent bundle) of constant curvature -1 correspond to pairs of projective surfaces with the same holonomy. Applying Bers Double Uniformization Theorem to this construction we prove a Uniformization Theorem for complex metrics on a 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 ▲]

We consider a symmetric matrix-valued Gaussian process $Y^{(n)}=(Y^{(n)}(t);t\ge0)$ and its empirical spectral measure process $\mu^{(n)}=(\mu_{t}^{(n)};t\ge0)$. Under some mild conditions on the covariance function of $Y^{(n)}$, we find an explicit expression for the limit distribution of $$Z_F^{(n)} := \left( \big(Z_{f_1}^{(n)}(t),\ldots,Z_{f_r}^{(n)}(t)\big) ; t\ge0\right),$$ where $F=(f_1,\dots, f_r)$, for $r\ge 1$, with each component belonging to a large class of test functions, and $$ Z_{f}^{(n)}(t) := n\int_{\R}f(x)\mu_{t}^{(n)}(\ud x)-n\E\left[\int_{\R}f(x)\mu_{t}^{(n)}(\ud x)\right].$$ More precisely, we establish the stable convergence of $Z_F^{(n)}$ and determine its limiting distribution. An upper bound for the total variation distance of the law of $Z_{f}^{(n)}(t)$ to its limiting distribution, for a test function $f$ and $t\geq0$ fixed, is also given. [less ▲]

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 ▲]

In this paper, we push forward the hypothesis that misalignment between expectations and aspirations crucially affects the educational outcomes of young adults. Using AddHealth, a dataset of 20,774 adolescents between the grades 7-12, we show that the difference in school performance between migrant children and natives lies within the aspirations and expectations that migrant children form. More specifically, we find that positive misalignment between aspirations and expectations is a driving force for higher effort and better education outcomes of immigrant teenagers in the USA. This force resolves the well-known immigrant paradox. Furthermore, this result is specific to migrant children and does not hold for second-generation migrant pupils. [less ▲]

Let G be a commutative connected algebraic group over a number field K, let A be a finitely generated and torsion-free subgroup of G(K) of rank r>0 and, for n>1, let K(n^{−1}A) be the smallest extension of K inside an algebraic closure K¯ over which all the points P∈G(K¯) such that nP∈A are defined. We denote by s the unique non-negative integer such that G(K¯)[n]≅(Z/nZ)s for all n≥1. We prove that, under certain conditions, the ratio between nrs and the degree [K(n^{−1}A):K(G[n])] is bounded independently of n>1 by a constant that depends only on the ℓ-adic Galois representations associated with G and on some arithmetic properties of A as a subgroup of G(K) modulo torsion.

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 ▲]

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.

An alternative or supplementary approach named as physical layer security has been proposed to afford an extra security layer on top of the conventional cryptography technique. In this paper, an overview of secrecy performance investigations over the classic Alice-Bob-Eve wiretap fading channels is conducted. On the basis of the classic wiretap channel model, we have comprehensively listed and thereafter compared the existing works on physical layer secrecy analysis considering the small-scale, large-scale, composite, and cascaded fading channel models. Exact secrecy metrics expressions, including secrecy outage probability (SOP), the probability of non-zero secrecy capacity (PNZ), average secrecy capacity (ASC), and secrecy bounds, including the lower bound of SOP and ergodic secrecy capacity, are presented. In order to encompass the aforementioned four kinds of fading channel models with a more \textit{generic} and \textit{flexible} distribution, the mixture gamma (MG), mixture of Gaussian (MoG), and Fox's $H$-function distributions are three useful candidates to largely include the above-mentioned four kinds of fading channel models. It is shown that they are flexible and general when assisting the secrecy analysis to obtain closed-form expressions. Their advantages and limitations are also highlighted. Conclusively, these three approaches are proven to provide a unified secrecy analysis framework and can cover all types of independent wiretap fading channel models. Apart from those, revisiting the existing secrecy enhancement techniques based on our system configuration, the on-off transmission scheme, jamming approach (including artificial noise (AN) & artificial fast fading (AFF)), antenna selection, and security region are presented.

A large number of criminal offences, not only cybercrime, is currently committed in a way that leaves digital traces which can serve as evidence. This data is in possession of service providers, often located abroad. The current model of cross-border gathering of evidence, based on mutual legal assistance, is considered too cumbersome and lengthy for the digital world. Similar reservations are made as regards the European Investigation Order. In response the EU Commission proposed the so-called e-evidence initiative. Based on mutual recognition, the new European Production Order would allow law enforcement in one Member State to request Internet service providers in another Member State to provide requested data in principle without involvement of the authorities of the latter state. This new system is a legal revolution at various levels, including its significant impact on the service providers offering services in the EU, redefining their duties towards law enforcement and influencing the relationship with their customers. This article examines the paradigm shift caused by that instrument and its consequences. [less ▲]

This study provides evidence for the US that the secular decline in the labor share is not only explained by technical change or globalization, but also by the dynamics of factor taxation, automation capital, and population growth. First, we empirically find indications of co-integration for the 1974-2008 period. Permanent effects on factor shares emanate from relative factor taxation. The latter also have a lasting effect on the use of robots. Variance decompositions reveal that taxing contributes to changes in the two income shares and in automation capital. Second, we analyse and calibrate a neoclassical growth model extended to include factor taxation, automation capital, and capital adjustment costs. The model is able to replicate the dynamics of the observed functional income distribution in the US during the 1965-2015 period. Counterfactual experiments suggest that the fall in the labor share would have been significantly smaller if labor and capital income tax rates had remained at their respective level of the 1960s.

Parkinson’s disease (PD) etiology is associated with genetic and environmental factors that lead to a loss of dopaminergic neurons. However, the functional interpretation of PD-associated risk variants and how other midbrain cells contribute to this neurodegenerative process are poorly understood. Here, we profiled >41,000 single-nuclei transcriptomes of postmortem midbrain tissue from 6 idiopathic PD (IPD) patients and 5 matched controls. We show that PD-risk variants are associated with glia- and neuron-specific gene expression patterns. Furthermore, Microglia and astrocytes presented IPD-specific cell proliferation and dysregulation of genes related to unfolded protein response and cytokine signalling. IPD-microglia revealed a specific pro-inflammatory trajectory. Finally, we discovered a neuronal cell cluster exclusively present in IPD midbrains characterized by CADPS2 overexpression and a high proportion of cycling cells. We conclude that elevated CADPS2 expression is specific to dysfunctional dopaminergic neurons, which have lost their dopaminergic identity and unsuccessful attempt to re-enter the cell cycle.

This paper develops a static model of endogenous task-based technical progress to study how factor scarcity induces technological progress and changes in factor prices. The equilibrium technology is multi-dimensional and not strongly factor-saving in the sense of Acemoglu (2010). Nevertheless, labor scarcity induces labor productivity growth. There is a weak but no strong absolute equilibrium bias. This model provides a plausible interpretation of the famous contention of Hicks (1932) about the role of factor prices and factor endowments for induced innovations. It may serve as a micro-foundation for canonical macro-economic models. Moreover, it accommodates features like endogenous factor supplies and a binding minimum wage. [less ▲]

How does population aging affect economic growth and factor shares in times of increasingly automatable production processes? The present paper addresses this question in a new macroeconomic model of automation where competitive firms perform tasks to produce output. Tasks require labor and machines as inputs. New machines embody superior technological knowledge and substitute for labor in the performance of tasks. The incentive to automate is stronger if wages are higher. Automation is shown to boost the aggregate demand for labor if and only if the incentives to automate are strong enough and to reduce the labor share. These predictions obtain even though automation is labor-augmenting in the reduced-form production function. Population aging due to a higher longevity or a decline in fertility may strengthen or weaken the incentives to automate. Irrespective of its source, population aging is predicted to increase the growth rate of per-capita GDP in the short and in the long run. The short-run effect of higher longevity on the labor share is positive whereas the effect of a declining fertility is negative. In the long run, population aging reduces the labor share. [less ▲]

For more than a century, scientists have been collecting behavioral data--an increasing fraction of which is now being publicly shared so other researchers can reuse them to replicate, integrate or extend past results. Although behavioral data is fundamental to many scientific fields, there is currently no widely adopted standard for formatting, naming, organizing, describing or sharing such data. This lack of standardization is a major bottleneck for scientific progress. Not only does it prevent the effective reuse of data, it also affects how behavioral data in general are processed, as non-standard data calls for custom-made data analysis code and prevents the development of efficient tools. To address this problem, we develop the Behaverse Data Model (BDM), a standard for structuring behavioral data. Here we focus on major concepts in behavioral data, leaving further details and developments to the project's website (https://behaverse.github.io/data-model/). [less ▲]

This paper studies the provision of urban green areas in cities when residents havepreferences for the size of and access to those areas. At the optimum, the number ofurban green spaces is a non-monotone function of distance to the city centre, whilethe sizes and distances to other urban green areas increase as one moves to the urbanfringe. This paper empirically investigates those properties for the 300 largest Europeancities by using the GMES Urban Atlas database (European Environmental Agency).The empirical analysis confirms the non-monotone relationship between the numberof urban green spaces and the distance to the city centre. The distance between twoparks also increases as one moves toward the urban fringe. Finally, richer cities areassociated with a denser network of urban green areas. [less ▲]
