European youth mobility seems to be fostering Europe's unequal pace of integration, which sees certain countries benefit at the expense of others (Ohmacht et al., 2009; van Mol & Timmerman, 2014). Using a comparative approach, the paper aims to relate a macro-level country-typology focussing on human capital with individual mobility-motivations on the micro-level. Our methodological approach is based on a secondary macro-data analysis and analyses of mobility-motivations of young people (micro-data) deriving from qualitative (N=152) and quantitative data (N=5,499) collected in six European countries. In order to examine correspondence between macro-conditions and micro-aspects, we relate information on mobility-motivations to the country-typology by allocating mobile youth to the respective types of their home country. The results show that the country-types compose different opportunity structures, which are reflected in individual motivations. Accordingly, different country-types can be seen as an example of the heterogeneity and inequality of European social and territorial mobility frames. [less ▲]

In this paper, we explore the effects of conspicuous goods as a means of social division between native citizens and migrants. We push forward the hypothesis that choosing a particular good can confer a sense of place. We introduce this idea in an international vertical differentiation market with two variants and two social groups: migrants and natives. Natives are narrow-minded since they attribute a positive social value to the variant that complies with their own consumption culture. Migrants are open-minded. When consumers belonging to different groups meet, they exchange information about their consumption habits and consumption well-being that reveals their consumption culture: narrow-minded versus open-minded. Consequently, after meeting, some consumers may change beliefs (narrow-minded to open-minded or vice versa) and consumption choices. Using a dynamic model, we fully elucidate the steady-state equilibrium and highlight the impact of nationalism on migrant integration. [less ▲]

We define a model with two countries and two vertically differentiated goods, a high and a low-quality variant, and heterogenous consumers with respect to their willingness to pay for quality. Consumers in one country are ethnocentric in consumption. They thrive additional satisfaction when consuming a domestic good rather than a foreign one since only the former can satisfy their sense of place. We investigate the role of trade costs and ethnocentric attitude in shaping the equilibrium configuration of the international duopoly. [less ▲]

Auslandserfahrungen sind nicht nur eine Möglichkeit, auf kulturelle Entdeckungsreise zu gehen. Sie gelten auch als Chance für junge Menschen, zu lernen und sich persönlich und beruflich weiterzuentwickeln. Entsprechend wird Jugendmobilität in der Jugendarbeit große Aufmerksamkeit geschenkt. Auch die Länder, die die Jugendlichen entsenden oder aufnehmen, können dabei profitieren – aber auf unterschiedliche Weise. Zu welchem Zweck gehen junge Menschen ins Ausland? Was motiviert sie dabei? Welche Barrieren müssen sie dafür überwinden? Welche Rolle spielt der familiäre Bildungshintergrund der Jugendlichen? Diese Fragen werden mit Fokus auf länderspezifische Unterschiede auf der Datenbasis des europäischen Forschungsprojekts MOVE untersucht, in das Wissenschaftler(innen) aus sechs europäischen Ländern involviert waren. Die Grundlage bildet zunächst eine Ländertypologie, die Humankapitalbewegungen durch Auslandsaufenthalte abbildet, welche je nach Mobilitätsfeld eher dem Sende- oder Empfängerland zugutekommen. Sie weist europäische Länder vier Typen zu: Mobilitätsförderern, Mobilitätsverlierern, Mobilitätsgewinnern und Mobilitätsverwertern. Besonders erstere und letztere sind gut für eine kontrastierende, ländervergleichende Betrachtung geeignet. Mobilitätsförderer sind Länder, deren junge Menschen im europäischen Ausland arbeiten, die aber selbst kein wichtiges Zielland für europäische Jugendliche sind (z.B. Ungarn und Rumänien). Mobilitätsverwerter sind attraktive Zielländer sowohl für kurz- als auch langfristige Mobilitäten und weisen damit bezüglich der Generierung und Verwertung von Humankapital ein ausgeglichenes Konto auf (z.B. Norwegen, Luxemburg und Deutschland). In einem kontrastierenden Vergleich werden Motivationen und Barrieren für Auslandsaufenthalte im Zusammenhang mit dem Bildungshintergrund junger Menschen aus Mobilitätsförder- und Mobilitätsverwerterländern analysiert. Hierfür werden die Individualdaten eines Onlinesurveys mit 18-29-Jährigen (N=4.719) aus Deutschland, Luxemburg, Norwegen, Ungarn und Rumänien den beiden Ländertypen zugeordnet und verglichen.

Coercion is used by one government (the "sender") to influence the trade practices of another (the "target"). We build a two-country trade model in which coercion can be exercised unilaterally or channeled through a "weak" international organization without enforcement powers. We show that unilateral coercion may be ineffective because signaling incentives lead the sender to demand a concession so substantial to make it unacceptable to the target. If the sender can instead commit to the international organization's dispute settlement mechanism, then compliance is more likely because the latter places a cap on the sender's incentives to signal its resolve.

Cobalt ferrite nanoparticles with controlled particle size are transferred from nonpolar into polar solvent by exchange of the as-synthesized oleic acid ligand shell with polyacrylic acid (PAA). The nanoparticles are highly monodisperse (sigmalog < 6%), and the ligand exchange synthesis has no measurable effect on particle size, shape, or size distribution. The stability of the aqueous particle dispersion without significant interparticle correlations as observed using small-angle X-ray scattering confirms the successful phase-transfer. [less ▲]

Existing proof-of-work cryptocurrencies cannot tolerate attackers controlling more than 50% of the network’s computing power at any time, but assume that such a condition happening is “unlikely”. However, recent attack sophistication, e.g., where attackers can rent mining capacity to obtain a majority of computing power temporarily, render this assumption unrealistic. This paper proposes RepuCoin, the first system to provide guarantees even when more than 50% of the system’s computing power is temporarily dominated by an attacker. RepuCoin physically limits the rate of voting power growth of the entire system. In particular, RepuCoin defines a miner’s power by its ‘reputation’, as a function of its work integrated over the time of the entire blockchain, rather than through instantaneous computing power, which can be obtained relatively quickly and/or temporarily. As an example, after a single year of operation, RepuCoin can tolerate attacks compromising 51% of the network’s computing resources, even if such power stays maliciously seized for almost a whole year. Moreover, RepuCoin provides better resilience to known attacks, compared to existing proof-of-work systems, while achieving a high throughput of 10000 transactions per second (TPS). [less ▲]

Malfunctions of voltage-gated sodium and calcium channels (SCN and CACNA1 genes) have been associated with severe neurologic, psychiatric, cardiac and other diseases. Altered channel activity is frequently grouped into gain or loss of ion channel function (GOF or LOF, respectively) which is not only corresponding to clinical disease manifestations, but also to differences in drug response. Experimental studies of channel function are therefore important, but laborious and usually focus only on a few variants at a time. Based on known gene-disease-mechanisms, we here infer LOF (518 variants) and GOF (309 variants) of likely pathogenic variants from disease phenotypes of variant carriers. We show regional clustering of inferred GOF and LOF variants, respectively, across the alignment of the entire gene family, suggesting shared pathomechanisms in the SCN/CACNA1 genes. By training a machine learning model on sequence- and structure-based features we predict LOF- or GOF- associated disease phenotypes (ROC = 0.85) of likely pathogenic missense variants. We then successfully validate the GOF versus LOF prediction on 87 functionally tested variants in SCN1/2/8A and CACNA1I (ROC = 0.73) and in exome-wide data from > 100.000 cases and controls. Ultimately, functional prediction of missense variants in clinically relevant genes will facilitate precision medicine in clinical practice. [less ▲]
