Der Beitrag geht von einem angebrochenen Zeitalter der Vergrenzungen aus und skizziert, wie die interdisziplinäre Grenzforschung und europäische Grenzraumforschung mit der Renaissance von Grenzen umgehen. Dabei wird die enge Verflechtung der Grenzraumforschung mit dem politischen Projekt der europäischen Integration und ihr Fokus auf die Permeabilität von Grenzen deutlich. Allerdings wird zugleich erkennbar, dass die Leitidee eines Europa ohne Grenzen in den letzten Jahrzehnten erheblich an Strahlkraft eingebüßt hat, zuletzt durch die temporäre Verstärkung der Kontrollen im Schengen-Raum (2015/2016) und die temporären Schließungen der EU-Grenzen (2020). Die zunehmend um sich greifenden Vergrenzungsprozesse in Grenzregionen werden außerdem im Alltag ihrer Einwohner*innen nachgezeichnet. Der Beitrag schlägt abschließend eine Perspektivweitung der europäischen Grenzraumforschung vor, die die Durabilität von Grenzen berücksichtigt und somit Vergrenzungen an den EU-Binnengrenzen besser zu verstehen hilft.

The European Union is a union under the rule of law and accordingly all exercise of public authority needs to conform with the principle of legality. The legal framework of the EU is, however, as much as that of any state or international organization, subject to change over time. That part of this legal framework specifically governing EU administration has been particularly dynamic. The central reason for this dynamism is to be found in the evolving nature of European integration, and in the changing requirements and conditions for implementing EU policies. The legal framework of administration has been both the subject of, and a response to, change in the ambient political and institutional environment. The EU, having started as an organization of six Member States focused on economic integration, has evolved into a Union of twenty-seven Member States now touching almost all elements of the exercise of public power in a modern society. The evolutionary development of the constitutional basis of EU law, with its many phases of Treaty reforms and change induced by case-law, finds its parallel in EU administrative law. European administrative law has in this process grown, changed, and indeed matured over time, and has emerged as an important, yet sometimes not well understood, factor which materially shapes policy in the EU and its achievement in reality. The rise of the importance of EU administrative law is itself attributable both to the specificities of European integration and to the general increase in the importance of administrative regulation in the past decades. On the one hand, the protection of the society against risks associated with private activity such as banking, food production, energy production and distribution, transport, or activities threatening to the environment, to name just a few, and the achievement of a balance between their benefits and dangers have become increasingly important subjects of attention. On the other hand, the provision of services and infrastructure necessary to ensure and protect basic standards of living such as pensions, health care, access to water, energy supply and telecommunications services have been the subject of mixed regimes, often still having a strong public service element, but increasingly left to private provision subject to various levels of market regulation. Both kinds of motivation for regulatory measures and their implementation by appropriate authorities have added to, and substantially changed, the broad character of public administration in Europe in recent decades. Such changes have occurred not just on a national, that is, Member State level, but also, pre-eminently, on the level of the European Community and now Union. Indeed, many of the changes have themselves been triggered on the European level as integral or at least adjuvant elements of the establishment of the European internal market. The role, then, of administrative law and administrative activity on the European level is extensive and important. Rules and principles governing the exercise of administrative functions, the organization of the institutions and bodies exercising these functions, and applicable procedures are the essence of EU administrative law. These are the subject of this book. There are, it must be observed, many perspectives from which one can view, analyse and comprehend both administration and administrative law. Three models or perspectives appear to us to be particularly helpful: administration and administrative law may be usefully considered from functional, organizational, and procedural standpoints. The functional aspect of administration refers to the totality of the tasks of administration, no matter who undertakes them and how they are carried out. The organizational perspective emphasises the organization and structure of the institutions, bodies, and actors engaged in undertaking such tasks. Finally, a procedural understanding of administration observes the processes which link the various actors and authorities in the performance of administrative functions. None of these models standing alone provides a fully rounded understanding or conceptualisation of the subject matter of the book. A proper analysis of EU administrative law cannot view it from only one of these perspectives. Taken together, however, these three standpoints do offer a comprehensive perception, giving the subject a more multi-dimensional shape, and thus allowing a more tractable presentation of what is very complex material. For this reason, we offer a discussion of each of these three perspectives — the functional, organizational, and procedural aspects of European Union administration and the associated legal framework — by way of introduction. The three models are, of course, closely interlinked and in reality scarcely separable but, for analytical and presentational clarity, they are here addressed separately. [less ▲]

This paper explores the interface between central banks and cryptocurrencies. Focusing on the European Central Bank (ECB), it identifies the potential threats that the rise of cryptocurrencies would pose to the basic and ancillary tasks of the ECB, in particular, its monetary policy operations and the exercise of its supervisory functions over credit institutions and payment systems. The paper finds that cryptocurrencies can potentially have both direct – through their potential impact on the price stability and monetary policy, and central banks’ monopoly over issuing base money – and indirect effects on central banks, mainly through the institutions and systems that fall under the ECB’s scope of competence. To address the challenges posed by cryptocurrencies, the ECB may take both legal (including supervisory and oversight) measures and non-legal (or technical) measures. With respect to technical measures, the ECB - to the extent falling within the scope of its competence - may focus on improving the efficiency of existing payment systems and addressing the existing frictions in market infrastructures to indirectly affect the cryptocurrency markets. Alternatively, it can venture into issuing Central Bank Digital Currency (CBDC). Regarding legal measures, central banks could envisage regulating cryptocurrencies either directly or indirectly. However, as the most significant potential impact of cryptocurrencies on central banks is likely to be indirect through the impact of cryptocurrencies on the banking and payment systems, and given the limitations on the ECB’s mandate and its regulatory and supervisory tools, it is apposite for the ECB to consider using indirect strategies and tools to influence cryptocurrency markets. This indirect approach can be implemented through the ECB’s existing supervisory and oversight powers over the banking and payment systems. This paper specifies the direct and indirect measures and assesses their merits in addressing the concerns about cryptocurrencies. [less ▲]

Description Logics (DLs) under Rational Closure (RC) is a well-known framework for non-monotonic reasoning in DLs. In this paper, we address the concept subsumption decision problem under RC for nominal safe $ELO_{\bot}$, a notable and practically important DL representative of the OWL 2 profile OWL 2 EL. Our contribution here is to define a polynomial time subsumption procedure for nominal safe $ELO_{\bot}$ under RC that relies entirely on a series of classical, monotonic $EL_{\bot}$ subsumption tests. Therefore, any existing classical monotonic $EL_{\bot}$ reasoner can be used as a black box to implement our method. We then also adapt the method to one of the known extensions of RC for DLs, namely Defeasible Inheritance-based DLs without losing the computational tractability. [less ▲]

The enhanced capabilities of large scale parallel and distributed platforms produce a continuously increasing amount of data which have to be stored, exchanged and used by various tasks allocated on different nodes of the system. The management of such a huge communication demand is crucial for reaching the best possible performance of the system. Meanwhile, we have to deal with more interferences as the trend is to use a single all-purpose interconnection network whatever the interconnect (tree-based hierarchies or topology-based heterarchies). There are two different types of communications, namely, the flows induced by data exchanges during the computations, and the flows related to Input/Output operations. We propose in this paper a general model for interference-aware scheduling, where explicit communications are replaced by external topological constraints. Specifically, the interferences of both communication types are reduced by adding geometric constraints on the allocation of tasks into machines. The proposed constraints reduce implicitly the data movements by restricting the set of possible allocations for each task. This methodology has been proved to be efficient in a recent study for a restricted interconnection network (a line/ring of processors which is an intermediate between a tree and higher dimensions grids/torus). The obtained results illustrated well the difficulty of the problem even on simple topologies, but also provided a pragmatic greedy solution, which was assessed to be efficient by simulations. We are currently extending this solution for more complex topologies. This work is a position paper which describes the methodology, it does not focus on the solving part. [less ▲]

On a generic metric measured space, we introduce a notion of improved concentration of measure that takes into account the parallel enlargement of k distinct sets. We show that the k-th eigenvalues of the metric Laplacian gives exponential improved concentration with k sets. On compact Riemannian manifolds, this allows us to recover estimates on the eigenvalues of the Laplace-Beltrami operator in the spirit of an inequality of Chung, Grigor’yan & Yau, Upper bounds for eigenvalues of the discrete and continuous Laplace operators. Adv. Math. 117(2), 165–178 (1996). [less ▲]

One of the problems perceived to be at the heart of the global financial crisis was an amalgamation of various commercial and investment banking activities under one entity, as well as the interconnectedness of the banking entities with other financial institutions, investment funds, and the shadow banking system. This paper focuses on various measures that aim to structurally separate the banking entities and their core functions from riskier financial activities such as (proprietary) trading or investments in alternative investment funds. Although banking structural reforms in the EU, UK, and the US have taken different forms, their common denominator is the separation of core banking functions from certain trading or securities market activities. Having reviewed the arguments for and against banking structural reforms and their varieties in major jurisdictions, including the EU, UK, US, France, and Germany, the paper argues that a more nuanced approach to introducing such measures at the EU level is warranted. Given the different market structures across the Atlantic and the lack of conclusive evidence on the beneficial impact of banking structural reforms, the paper concludes that the withdrawal of the banking structural reforms proposal by the European Commission has been a prudent move. It seems that in the absence of concrete evidence, experimenting with structural reforms at the Member-State level would be less costly and would provide for opportunities for learning from smaller mistakes that could pave the way for a more optimal approach to introducing banking structural reforms at the European level in the future.

The need to belong is fundamental to human beings and constitutes a basis for subjective well-being. It is closely linked to further concepts, such as identification, connectedness, attachment, fitting in and feeling “at home”. The present contribution will focus on the sense of belonging in the context of migration in its different facets - cultural, social and spatial - and in relation to different points of reference - national, ethnic and transnational belonging. Applying the lens of cultural psychology of semiotic mediation, the development of a sense of belonging will be discussed with regard to first generation migrants and their second-generation offspring in a life span perspective, drawing on concepts such as proculturation as well as the Trajectory Equifinality Approach.

Regional foreign banks expanded quickly over the past decade in developing and emerging countries and have a growing influence in banking systems. We question whether the development of African regional foreign banks, also called Pan-African banks, influences financial inclusion of firms and households. To this end, we combine the World Bank Global Findex database and the World Bank Enterprise Surveys with a hand-collected database on the presence of regional foreign banks. We find that Pan-African banks presence increases firms’ access to credit and limited evidence that they favor financial access of the middle class by restoring confidence in banks. We suggest that this impact is related to the adoption of an aggressive strategy aiming at gaining market shares rather than through the exploitation of informational and technological advantages.

The aim of this chapter is to highlight the different issues that one faces when trying to ensure the fundamental right to data protection of blockchain users. The provisions of the General Data Protection Regulation are used as an example of the difficulties. Here, two principal issues are addressed: issues regarding the addressees of the General Data Protection Regulation's provisions and issues regarding the qualification and treatment of data available on permissionless and permissioned blockchains. Finally, this article highlights the consequences that these uncertainties may have on the protection of users’ fundamental rights and the necessity to ensure legal certainty through additional guidance from the European legislator or upcoming case-law.
