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.

Under the General Data Protection Regulation (GDPR), transparency of information becomes an obligation aimed at creating an ecosystem where data subjects understand and control what happens to their personal data. The definition of transparency stresses its user-centric nature, while design considerations to comply with this obligation assume central importance. This article focuses on the icons established by the GDPR Art. 12.7 to offer “a meaningful overview of the intended processing”. Existing attempts to represent data protection through icons have not met widespread adoption and reasons about the strengths and weaknesses of their creation and evaluation are here discussed. Building on this analysis, we present an empirical research proposing a new icon set that responds to GDPR requirements. The article also discusses the challenges of creating and evaluating such icon set and provides some future directions of research for effective an effective implementation and standardization.

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 ▲]

Women are disproportionately in low‐paid work compared to men so, in the absence of rationing effects on their employment, they should benefit the most from minimum wage policies. This study examines the change in the gender wage gap around the introduction of minimum wages in Ireland and the United Kingdom (U.K.). Using survey data for the two countries, we develop a decomposition of the change in the gender differences in wage distributions around the date of introduction of minimum wages. We separate out “price” effects attributed to minimum wages from “employment composition” effects. A significant reduction of the gender gap at low wages is observed after the introduction of the minimum wage in Ireland, while there is hardly any change in the U.K. Counterfactual simulations show that the difference between countries may be attributed to gender differences in non‐compliance with the minimum wage legislation in the U.K. [less ▲]

The dual‐process model, describing addictive disorders as resulting from an imbalance between increased automatic approach behaviors towards the substance and reduced abilities to control these behaviors, constitutes a sound theoretical framework to understand alcohol‐use disorders. The present study aimed at exploring this imbalance at behavioral and cerebral levels in binge drinking, a pattern of excessive alcohol consumption frequently observed in youth, by assessing both reflective control abilities and automatic processing of alcohol‐related stimuli. For this purpose, 25 binge drinkers and 25 comparison participants performed a Go/No‐Go task during electrophysiological recording. Inhibition abilities were investigated during explicit (ie, distinguishing alcoholic versus nonalcoholic drinks) and implicit (ie, distinguishing sparkling versus nonsparkling drinks, independently of their alcohol content) processing of beverage cues. Binge drinkers presented poorer inhibition for the explicit processing of beverage cues, as well as reduced N200 amplitude for the specific processing of alcohol‐related stimuli. As a whole, these findings indicated inhibition impairments in binge drinkers, particularly for alcohol cues processing and at the attentional stage of the cognitive stream. In line with the dual‐process model, these results support that binge drinking is already characterized by an underactivation of the reflective system combined with an overactivation of the automatic system. Results also underlined the influence of explicit processing compared with implicit ones. At the clinical level, our findings reinforce the need to develop intervention methods focusing on the inhibition of approach behaviors towards alcohol‐related stimuli. [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 mobile app Schnëssen is intended to establish a state-of-the-art digital platform to collect data on the present-day language situation of Luxembourgish by means of crowd-sourcing and to document and present results to a broader public. Users can participate in a large set of audio recordings tasks and in sociolinguistic surveys. By presenting all audio recordings via an interactive map, participants can explore the language variation of their language. In the first year of data collection, around 210.000 recordings could be collected for numerous variation phenomena from all linguistic levels and over 2800 sociolinguistic questionnaires have been filled out. The app allowed us to compile thus the largest systematic spoken language corpus of Luxembourgish. [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.

La jurisprudence récente de la Cour de justice suggère que la fonction du système juridictionnel de l’Union, composé des juridictions nationales et européennes stricto sensu, n’est pas seulement de garantir le contenu matériel de l’Etat de droit. Les principes régissant ce système et ses mécanismes constituent en effet autant de composantes du contenu de l’Etat de droit et font du système juridictionnel une garantie à part entière de cette valeur fondatrice de l’Union. D’un point de vue procédural, la fonction nouvelle du système juridictionnel s’exprime par les obligations incombant aux Etats membres et par l’office européen du juge national, dont la pratique a transformé, dans un esprit de loyauté juridictionnelle et de volontarisme, les mécanismes du renvoi préjudiciel et du mandat d’arrêt européen en garanties systémiques de l’Etat de droit. La présente contribution propose une modélisation nouvelle de l’Union qui permet de visualiser le rapprochement du contenu systémique de la protection juridictionnelle et du principe européen de légalité mais aussi la suprématie du principe de loyauté qui non seulement affecte le principe de légalité mais fait aussi émerger des principes fonctionnels dérivés tels que la primauté et la confiance mutuelle.

In light of the current tendency of regulating space resources activities through national legislation, this article addresses the validity of such emerging practice under Public International Law (PIL). To this end, the article first recalls the traditional debate between Monism and Dualism about the relationship between municipal and international law. This analysis is further completed by focusing also on the counter-position between two cornerstones of PIL, the principles of State sovereignty and Pacta Sunt Servanda. Next, the article assesses the exposure of national law “integrating” international law, focusing on ex post conflicts between the two sources as regulated by Article 27 of the Vienna Convention on the Law of Treaties. Accordingly, the article will show that States not willing to adapt their national laws will have to face international responsibility under the Draft Articles on State Responsibility for Internationally Wrongful Acts. Based on the above, the article then presents the related legal consequences, both at the international and national levels. Finally, the article closes by assessing the role of interpretative declarations and the defense of persistent objector as possible legal tools for dissenting States. [less ▲]

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 ▲]

We show that the k-th eigenvalues of the metric Laplacian gives exponential improved concentration with k sets.
