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 ▲]

Preliminary evidence suggests that childhood maltreatment is associated with higher problematic social media use (PSMU). It has also been established that childhood emotional maltreatment (CEM) is associated with body image dissatisfaction (BID). However, the direct and indirect impacts of CEM on PSMU via BID remain untested. The present study examined these direct and indirect relationships among a sample of 385 adolescents (mean age 15.62 years, range 14–18 years). Results indicated that female adolescents had higher levels of CEM, BID, and PSMU compared to males. Structural equation modeling indicated that CEM was indirectly associated with PSMU via BID among males. However, only BID was positively associated with PSMU among females. The findings are in accordance with theoretical models suggesting that individuals’ core characteristics including early childhood experiences and psychopathological factors are associated with different types of specific internet-use disorders.

South Africa is currently one of the world’s most unequal countries, with massive income inequality, millions of people living in poverty without access to basic services and amenities, unemployment rates consistently above 20% and the top 10% of the population receiving two thirds of the total income. Government economic policies on poverty reduction in the decades since the advent of democracy in South Africa in 1994 have been unable to eradicate the extreme racialised inequality which was the basis of the 342 years of colonialism and apartheid which were characterised by systematic dispossession and socio-economic marginalisation of South Africa’s majority Black population and the systematic privileging of the minority White population. While this history is not the primary focus of this paper, it nonetheless provides useful context. The paper’s primary focus is on the more recent normative and legal challenges of post-1994 South Africa that have resulted in further entrenching socio-economic inequality and contributing to the rise of populism. In this paper we argue that the dire living conditions of a large proportion of the population and disillusionment with the State’s ability to deliver on its promises in this regard, along with the poor implementation of social and economic rights have led to the development of a populist culture in South African politics.

Reducing pollutant emissions and promoting sustainable mobility solutions, including Public Transport (PT), are increasingly becoming key objectives for policymakers worldwide. In this work we develop an optimal vehicle scheduling approach for next generation PT systems, considering the instance of mixed electric / hybrid fleet. Our objective is that of investigating to what extent electrification, coupled with optimal fleet management, can yield operational cost savings for PT operators. We propose a Mixed In- teger Linear Program (MILP) to address the problem of optimal scheduling of a mixed fleet of electric and hybrid / non-electric buses, coupled with an ad-hoc decomposition scheme aimed at enhancing the scalability of the proposed MILP. Two case studies arising from the PT network of the city of Luxem- bourg are employed in order to validate the model; sensitivity analysis to fleet design parameters is performed, specifically in terms of fleet size and fleet composition. Conclusions point to the fact that careful modelling and handling of mixed-fleet conditions are necessary to achieve operational savings, and that marginal savings gradually reduce as more conventional buses are replaced by their electric counterparts. We believe the methodology proposed may be a key part of advanced decision support systems for policymakers and operators that are dealing with the on-going transition from conventional bus fleets towards greener transport solutions.

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 ▲]

Für die großflächige, deutschlandweite Kartierung und Analyse der Familiennamen (FamilienN, im Folgenden steht „N“ für Name(n)) stellt bis heute die nach Postleitzahlen gegliederte Datenbank der Telefonanschlüsse, wie sie im Telefonbuch der Deutschen Telekom von 2005 verzeichnet sind die Datenbasis des Projekts 'Deutscher Familiennamenatlas' dar. Im Folgenden werden wir eine neue umfangreiche Datenbasis der deutschen FamilienN vorstellen, die die bisherige um eine historische Dimension erweitern wird. Es handelt sich um die Datenbank der Verlustlisten der Kriegsteilnehmer des Ersten Weltkriegs, die mit ihren rund 7,7 Millionen Namenträgern aus allen Gebieten des damaligen Deutschen Reichs die gesamte FamilienN-Landschaft des ausgehenden 19. Jh. umfassen. Mit dieser neuen Datenbasis wird es möglich sein, die heutige FamilienN-Landschaft mit derjenigen vor 130 Jahren zu vergleichen und damit zum ersten Mal die regionale Festigkeit bzw. Veränderung der FamilienN zu erforschen. Unberührt von den großen europäischen Migrationswellen des 20. Jh. und erst am Beginn der durch die Industrialisierung beschleunigten Urbanisierung, repräsentieren die Verlustlisten die Namenverteilung einer im Vergleich zu heute deutlich weniger mobilen, überwiegend ländlichen Gesellschaft. Über diese neue Kartierungsgrundlage hinaus leisten die Verlustlisten wertvolle Dienste bei der Etymologisierung, bei sprachgeschichtlichen, dialektologischen oder graphematischen Fragestellungen sowie für die Migrationsforschung.

In this paper, the cell based smoothed finite element method is extended to solve stochastic partial diff erential equations with uncertain input parameters. The spatial field of Young's moduli and the corresponding stochastic results are represented by Karhunen-Lo eve expansion and polynomial chaos expansion, respectively. The Young's Modulus of structure is considered to be random for stochastic static as well as free vibration problems. Mathematical expressions and the solution procedure are articulated in detail to evaluate the statistical characteristics of responses in terms of static displacements and free vibration frequencies. The feasibility and eff ectiveness of the proposed SGCS-FEM method in terms of accuracy and lower requirement on the mesh size in the solution domain over that of conventional FEM for stochastic problems are demonstrated by carefully chosen numerical examples. From the numerical study, it is inferred that the proposed framework is computationally less demanding without compromising accuracy. [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.
