Abstract The COVID-19 pandemic gave rise to a wave of adoption of soft law at EU level. As a regulatory tool, soft law is associated with greater efficiency, because it can be adopted without the necessity to respect complex procedural rules. In addition, it is not binding and it leaves it to its addressees to adapt according to their needs and possibilities. On the other hand, it raises questions about legitimacy, competences and control. The paper identifies the problematic aspects of EU soft law and explains why the current crisis represents an opportunity to address them. [less ▲]

The automated enrichment of mass-digitised document collections using techniques such as text mining is becoming increasingly popular. Enriched collections offer new opportunities for interface design to allow data-driven and visualisation-based search, exploration and interpretation. Most such interfaces integrate close and distant reading and represent semantic, spatial, social or temporal relations, but often lack contrastive views. Inspect and Compare (I\&C) contributes to the current state of the art in interface design for historical newspapers with highly versatile side-by-side comparisons of query results and curated article sets based on metadata and semantic enrichments. I\&C takes search queries and pre-curated article sets as inputs and allows comparisons based on the distributions of newspaper titles, publication dates and automatically generated enrichments, such as language, article types, topics and named entities. Contrastive views of such data reveal patterns, help humanities scholars to improve search strategies and to facilitate a critical assessment of the overall data quality. I\&C is part of the impresso interface for the exploration of digitised and semantically enriched historical newspapers. [less ▲]

Social bonds are important for individuals as bonds can have manifold positive impacts, such as emotional or practical support, and may be beneficial for individuals’ well-being or opportunities within society. However, spatial mobility and especially international migration have the potential to diversify and destabilize people’s social bonds and may thus positively or negatively influence the impacts of social bonds. To date, there is a lot of research focussing on how migration affects partnership or family bonds, but there is a lack of research that places friendships at the core of the analysis. This is surprising, as friendships are a fundamental part of people’s system of social bonds. They can be seen as a key factor of social support in coping with stressful situations in everyday life, such as finding a place within the new host society, and are directly related to individual life satisfaction. Therefore, it is important to reflect on how situations in migrants’ circle of friends change in the course of migration. Using data from the first wave of the German Emigration and Remigration Panel Study (GERPS), in this chapter, I address this issue by focussing on self-perceived changes in the circle of friends in the course of international migration. The specific focus here is on how individual personality characteristics such as risk attitude, locus of control, or emotional attachment to the host and the home country (in case of this article Germany) are related to a positive or negative perception of the developments of emigrants’ circles of friends shortly after migration. As research on friendships suggests that specific sociodemographic groups differ in how they manage their networks, this chapter also considers gender- and age-specific perspectives. Results show that individual perceptions of the developments within the circle of friends in course of migration differ. Concerning the factors related to a positive or a negative perception of the development, it becomes apparent that the different personality attributes play a significant role. Concerning differences across sociodemographic groups, I found only slight differences between men and women but stronger differences across age groups. [less ▲]

The main objective of the German Emigration and Remigration Panel Study (GERPS) is to establish a longitudinal data set that provides information on life trajectories of international migrants. However, a large amount of paradata were also collected in order to obtain meta-information on respondents’ survey participation. This auxiliary information can help to optimize data quality at all stages of the survey process. By continuing the existing discussion in the field of online surveys, this chapter pursues a twofold objective: it reflects device usage (mobile vs. computer) and elucidates determinants of device choice. In particular, it analyses whether selectivity effects due to respondent’s device choices bias the sample. Moreover, this chapter investigates differences in response time between devices to detect differences in response burden. The analysis of response burden differences by device is an important issue, since an increased device-specific response burden can be a predictor of actual and further panel dropouts. In both device-specific selectivity and survey burden, only slight differences were found between mobile and desktop devices. Using these data, the following paper addresses the need to analyse potential sources of survey error and provides evidence that GERPS data do not appear to contain noteworthy bias attributed to device usage.

This contribution deals with the daily cross-border practices of the inhabitants of Saarland, Lorraine, Luxembourg, Rhineland-Palatinate and Wallonia. It will deal with various aspects of unquestioned activities that are regularly carried out in a country other than the country of residence. The dimension of regular physical mobility in a transnational perspective will have to be integrated into this analysis insofar as cross-border everyday practices represent routine activities associated with a circular (pendular) movement that extends beyond neighbouring national territories. From this point of view, it should be emphasised that the Greater Region SaarLorLux is already experiencing pronounced cross-border mobility phenomena: mobility in the context of employment and in the context of residential migration.

This paper studies the stabilization of optimal equilibrium profiles in nonisothermal plug-flow tubular reactors actuated by a heat exchanger that acts as a distributed control input. As a first result, we show that the heat exchanger temperature that achieves the minimal value of the steady-state reactant concentration at the outlet is the maximal allowed one. Then, a control strategy is proposed to reach these optimal equilibrium profiles. As main results, we prove that the control law stabilizes exponentially the nonlinear dynamics around the optimal equilibrium while it converges to the optimal heat exchanger temperature. In addition we show that the control law is optimal for some cost criterion of infinite-horizon integral type. Finally, the main results are illustrated with some numerical simulations. [less ▲]

Exciton band structures analysis provides a powerful tool to identify the exciton character of materials, from bulk to isolated systems, and goes beyond the mere analysis of the optical spectra. In this work, we focus on the exciton properties of molybdenum sisulfide (MoS 2 ) by solving the ab initio many-body Bethe–Salpeter equation, as a function of momentum, to obtain the excitation spectra of both monolayer and bulk MoS 2 . We analyse the spectrum and the exciton dispersion on the basis of a model excitonic Hamiltonian capable of providing an efficient description of the excitations in the bulk crystal, starting from the knowledge of the excitons of a single layer. In this way, we obtain a general characterization of both bright and darks excitons in terms of the interplay between the electronic band dispersion (i.e. interlayer hopping) and the electron–hole exchange interaction. We identify for both the 2D and the 3D limiting cases the character of the lowest-energy excitons in MoS 2 , we explain the effects and relative weights of both band dispersion and electron–hole exchange interaction and finally we interpret the differences observed when changing the dimensionality of the system.

We calculate the time evolution of the transient reflection signal in an MoS2 monolayer on a SiO2/Si substrate using first-principles out-of-equilibrium real-time methods. Our simulations provide a simple and intuitive physical picture for the delayed, yet ultrafast, evolution of the signal whose rise time depends on the excess energy of the pump laser: at laser energies above the A- and B-exciton, the pump pulse excites electrons and holes far away from the K valleys in the first Brillouin zone. Electron–phonon and hole–phonon scattering lead to a gradual relaxation of the carriers toward small Active Excitonic Regions around K, enhancing the dielectric screening. The accompanying time-dependent band gap renormalization dominates over Pauli blocking and the excitonic binding energy renormalization. This explains the delayed buildup of the transient reflection signal of the probe pulse, in excellent agreement with recent experimental data. Our results show that the observed delay is not a unique signature of an exciton formation process but rather caused by coordinated carrier dynamics and its influence on the screening. [less ▲]
