Inclusive education has become a leading theme internationally over the past several decades, as it addresses key issues, often controversial, of exclusion/inclusion, learning opportunities, and educational equality and justice. Among international organizations as well as supranational governments, we find an increasing emphasis on recognizing diversity and enabling education for all. This is visible in the Salamanca Declaration (1994), the overall “education-for-all” agenda, the Sustainable Developments Goals (e.g., Education, SDG 4), and the worldwide ratification of the UN Convention on the Rights of People with Disabilities (e.g., Article 24 on Education), which mandates among state parties the establishment of an inclusive education system across levels, from early childhood to lifelong learning. This frame of reference is not only significant in terms of definitions and contents but also in the context of the strengthening of world society. The world societal level is not the same as what occurs in the relations between nation states, as important as such learning in policies and practices may be but extends beyond. This is evident in the definition of “inclusion” that has become significant internationally as a category signifying attempts to guarantee access and participation in different levels of education systems, but one that has contrasting and divergent understandings, implications, and implementation consequences between national and local contexts. The goal of participation that follows normatively and legally from such understandings of inclusion, is recontextualized differently, sometimes even paradoxically, when in fact segregated and separate settings are extended under the banner of inclusion. In Germany, for example, despite inclusion discourse flowing from such international agendas that focus on processes of integration and participation, the structures, cultures, and practices that disadvantage and disable continue to exist or even become strengthened. Even if the myriad dimensions of diversity are increasingly discussed and intersectional approaches become more important, the emphasis on difference of disability or “special educational needs” continues. In educational research, numerous publications have delineated the establishment of inclusive education from diverse perspectives. Over the past decade in particular, this has occurred in relation to the UN CRPD, which also implies a connection to the world society-frame; however, theorization and in-depth empirical analyses are lacking to explain more recent developments on multiple levels. Even for nation-states, few systematic and comparative studies have analyzed the diverse forms of inclusive education in different contexts. The consequence has been a divergence between the national discourses of inclusive education, for example, in the German-speaking countries, that remain focused on special educational needs, and the more global discourse that understands inclusive education in human rights terms and a key developmental process in democracies. Although some recent comparative research projects and dissertations provide insights into specific country contexts, a more comprehensive publication that collects such research results of international inclusive educational research has been lacking. Furthermore, the opportunity presents itself to extend the dialogue through a world society perspective on inclusion to reflect global inequalities via integrating case studies from the Global South. International and intercultural perspectives enable the investigation of structures, cultures and practices of different countries to the crucial comparison of educational processes. This is especially necessary in the case of inclusive education, whether as a source of inspiration, a reflexive critique of taken-for-grantedness or as a means to identify disparities and social inequalities. Thus, in several dozen chapters, the Handbook Inclusion International presents diverse global, national, and local perspectives on inclusive education. [less ▲]

Motivation: Machine learning in the biomedical sciences should ideally provide predictive and interpretable models. When predicting outcomes from clinical or molecular features, applied researchers often want to know which features have effects, whether these effects are positive or negative, and how strong these effects are. Regression analysis includes this information in the coefficients but typically renders less predictive models than more advanced machine learning techniques. Results: Here we propose an interpretable meta-learning approach for high-dimensional regression. The elastic net provides a compromise between estimating weak effects for many features and strong effects for some features. It has a mixing parameter to weight between ridge and lasso regularisation. Instead of selecting one weighting by tuning, we combine multiple weightings by stacking. We do this in a way that increases predictivity without sacrificing interpretability. Availability and Implementation: The R package starnet is available on GitHub: https://github.com/rauschenberger/starnet. [less ▲]

Several studies have shown that problematic use of online sexual activities (OSAs) can constitute a dysfunctional coping strategy that reflects a compensatory usage of the Internet. Yet, some specific risk factors—widely investigated in the field of general problematic Internet use—have to date been scarcely studied within the context of OSA. Hence, the goal of this study was to test a theoretical model in which self‐esteem, loneliness, and social anxiety are hypothesized to predict the type of OSAs favored and their potential addictive use. To this end, an online survey was conducted in a sample of self‐selected men who used OSAs on a regular basis (N = 209). Results showed that low self‐esteem is positively associated with loneliness and high social anxiety, which were in turn positively related to involvement in two specific OSAs: use of pornography and the search for online sexual contacts. Higher engagement in these OSA activities was related to symptoms of addictive usage. These findings underline the importance in psychological interventions of taking into account the specific OSA practiced to improve self‐esteem and to reduce loneliness and symptoms of social anxiety [less ▲]

We analyze the effects of taxation in two-sided matching markets where agents have heterogeneous preferences over potential partners. Our model provides a continuous link between models of matching with and without transfers. Taxes generate inefficiency on the allocative margin, by changing who matches with whom. This allocative inefficiency can be non-monotonic, but is weakly increasing in the tax rate under linear taxation if each worker has negative non-pecuniary utility of working. We adapt existing econometric methods for markets without taxes to our setting, and estimate preferences in the college-coach football market. We show through simulations that standard methods inaccurately measure deadweight loss. [less ▲]

We devise practical algorithms for this problem depending on the ranks of P and Q. This problem finds its motivation in cryptanalysis: we show how to significantly improve previous algorithms for solving the approximate common divisor problem and breaking CLT13 cryptographic multilinear maps.

This paper affirms that external relations are outside the scope of Article 47 of the Charter. This does not however mean that the principle of judicial protection and the right of access to an independent tribunal have only an internal EU law dimension. In Opinion 1/17, The Court of Justice could assess the CETA’s compatibility with the right of access to an independent tribunal without having recourse to Article 47 of the Charter, on the ground either of the principle of autonomy or of the compatibility with the substantive provisions of the common commercial policy. This paper argues that while judicial protection as part of the autonomy claim could meet some conceptual limits, promoting judicial protection as part of the common commercial policy could reinforce the perception that the Union is a credible and influential actor in international trade and in international procedural law.

A new orthogonal decomposition of strain tensor into compressive/tensile parts is implemented in the phase eld model to maintain the physical crack propagation behavior. An e cient operator split scheme with the introduction of projection tensors is proposed to facilitate the numerical implementation of the new spectral decomposition. Formulations of the present failure model accounting the unilateral contact condition are given analytically and explicitly, which implies an extremely robust computational model. In particular, compared to the existing models, the present framework is general, which can be applied to all possible elastic behavior, such as isotropic, orthotropic, and totally anisotropic elastic material. A detailed comparison of fracture response predicted by the present models with the literature approaches is then provided. It is shown that orthogonal decomposition is able to simulate various failure scenarios. Especially, this formulation shows a very remarkably prediction compared to experimental observation for the case of compression load. [less ▲]

System development is not a linear, one-shot process. It proceeds through refinements and revisions. To support assurance that the system satisfies its requirements, it is desirable that continuous verification can be performed after each refinement or revision step. To achieve practical adoption, formal verification must accommodate continuous verification efficiently and effectively. Model checking provides developers with information useful to improve their models only when a property is not satisfied, i.e., when a counterexample is returned. However, it is desirable to have some useful information also when a property is instead satisfied. To address this problem we propose TOrPEDO, an approach that supports verification in two complementary forms: model checking and proofs. While model checking is typically used to pinpoint model behaviors that violate requirements, proofs can instead explain why requirements are satisfied. In our work, we introduce a specific notion of proof, called Topological Proof. A topological proof produces a slice of the original model that justifies the property satisfaction. Because models can be incomplete, TOrPEDO supports reasoning on requirements satisfaction, violation, and possible satisfaction (in the case where satisfaction depends on unknown parts of the model). Evaluation is performed by checking how topological proofs support software development on 12 modeling scenarios and 15 different properties obtained from 3 examples from literature. Results show that: (i) topological proofs are ≈60% smaller than the original models; (ii) after a revision, in ≈78% of cases, the property can be re-verified by relying on a simple syntactic check.

The rank $n$ swapping multifraction algebra is a field of cross ratios up to $(n+1)\times (n+1)$-determinant relations equipped with a Poisson bracket, called the {\em swapping bracket}, defined on the set of ordered pairs of points of a circle using linking numbers. Let $D_k$ be a disk with $k$ points on its boundary. The moduli space $\mathcal{X}_{\operatorname{PGL}_n,D_k}$ is the building block of the Fock--Goncharov $\mathcal{X}$ moduli space for any general surface. Given any ideal triangulation of $D_k$, we find an injective Poisson algebra homomorphism from the rank $n$ Fock--Goncharov algebra for $\mathcal{X}_{\operatorname{PGL}_n,D_k}$ to the rank $n$ swapping multifraction algebra with respect to the Atiyah--Bott--Goldman Poisson bracket and the swapping bracket. Two such injective Poisson algebra homomorphisms related to two ideal triangulations $\mathcal{T}$ and $\mathcal{T}'$ are compatible with each other under the flips. [less ▲]

Studies on the connection between migration and urbanity are usually concerned with conditions and developments in cities. The presence of ‘urbanity’ in rural space is the topic of the present contribution. It will be discussed using the example of residential migration in the Greater Region SaarLorLux. The massive influx of residential migrants from Luxembourg into the border regions of the neighbouring countries is a relatively recent phenomenon, the main cause of which lies in the developments in the real-estate market in the Grand Duchy of Luxembourg. This phenomenon is of special interest for the topic of migration in rural areas in two regards: because of the important demographic changes produced by the residential migrants in individual border villages and because of the complex composition of the group of residential migrants, which is extremely differentiated regarding the dimension rural – urban. Central to the article is the question, whether urban attitudes and practices become visible in German border villages, and, if so, how the migratory movement from Luxembourg influences this ‘rural urbanity’. Furthermore, taking the everyday practices of the residential migrants as starting point, it asks in how far the dichotomy urbanity - rurality presents a conceptual approach for the examination of individual and structural integration processes.

In recent decades, Border Studies have gained importance and have seen a noticeable increase in development. This manifests itself in an increased institutionalization, a differentiation of the areas of research interest and a conceptual reorientation that is interested in examining processes. So far, however, little attention has been paid to questions about (inter)disciplinary self-perception and methodological foundations of Border Studies and the associated consequences for research activities. This thematic issue addresses these desiderata and brings together articles that deal with their (inter)disciplinary foundations as well as method(olog)ical and practical research questions. The authors also provide sound insights into a disparate field of work, disclose practical research strategies, and present methodologically sophisticated systematizations. [less ▲]

Product Line Engineering (PLE) is a crucial practice in many software development environments where software systems are complex and developed for multiple customers with varying needs. At the same time, many development processes are use case-driven and this strongly influences their requirements engineering and system testing practices. In this paper, we propose, apply, and assess an automated system test case classification and prioritization approach specifically targeting system testing in the context of use case-driven development of product families. Our approach provides: (i) automated support to classify, for a new product in a product family, relevant and valid system test cases associated with previous products, and (ii) automated prioritization of system test cases using multiple risk factors such as fault-proneness of requirements and requirements volatility in a product family. Our evaluation was performed in the context of an industrial product family in the automotive domain. Results provide empirical evidence that we propose a practical and beneficial way to classify and prioritize system test cases for industrial product lines. [less ▲]

Building on this, we will develop our idea of a cross-border practice formation that breaks with the premises of traditional cooperation research, and we provide an alternative perspectivation by outlining four challenges of CBC (chapter 4).

When a new type of coronavirus was first reported in China in December 2019, it was not yet clear how rapidly and in what a short time frame COVID-19 would affect the entire world. In January 2020, Wuhan, the capital of Hubei, was quarantined and just two months later, the virus had spread to Central Europe; a subsequent wave of infections followed in many places, including the United States. As a result, presumed certainties began to erode: freedom of movement was restricted, entry restrictions were imposed and, paradoxically, precisely 25 years after the Schengen Agreement came into force, many EU internal borders were closed. This article focuses on these border closings, but also deals with drawing social boundaries in the wake of the pandemic. Thus, the border geographies examined range from the subject level to the global level and will be put into context with the security measures that have been introduced, the orderings and ordinances used, political re-nationalization reflexes and civil society resistance. The article ends with an outlook of some additional topics and questions from the perspective of Border Studies with and after the COVID-19 pandemic. [less ▲]

Die Border Studies haben seit den 1990er Jahren einen tiefgreifenden Wandel durchlaufen, der die Beschäftigung mit Grenz(ziehung)en als unhinterfragte Gegebenheiten relativiert hat. Die Neuorientierung stützt sich auf konstruktivistische Zugänge und fragt nach den Prozessen der Einsetzung, Relativierung, Verschiebung oder Überwindung von Grenzen.
