Despite operating in highly constrained legal environments, executive actors may act in a constitutive capacity. This observation prompts a critical assessment of the role of procedural principles in EU administrative law. As norms of conduct deployed by executive bodies during the process of norm concretization, procedural principles may have legal dimensions that, while constitutionally relevant, may not come to the fore in judicial review. The chapter develops this argument with regard to the multifaceted character of the duty to give reasons. It argues that, as a norm of conduct, the duty to give reasons ought to ensure the constitutional embeddedness of the constitutive action of EU executive bodies. Such role is consistent both with the original relevance of the duty to give reasons to the law of integration (in the context of the European Coal and Steel Community) and with the current EU constitutional framework. The latter justifies reinstituting the original constitutional function of the duty to give reasons, irrespective of its current scope in the context of judicial review. [less ▲]

The chapter approaches the EU administrative institutions as catalysts of the development of administrative law of the European Union. As a chapter of the Oxford Handbook on Comparative Administrative Law, it explains the main traits of those institutions, how legal scholarship has portrayed them and how it has addressed the core aspects of their legal regimes. Furthermore, it traces the emergence and current state of EU administrative law, characterising the different roles comparative administrative law has had at different stages. It highlights the initial dissonance between the specificities of the EU administrative institutions and the state-matrix of general principles that were developed on the basis of functional comparison; the role of legal scholarship in shaping EU administrative law, in its efforts to give effect to an “utopia” (Chiti, 2007) of an integrated administration constitutionally framed by general principles and fundamental rights; the limits of resorting to comparative administrative law in the context of EU integration and, briefly, the crossroads at which EU administrative law currently stands.

In the frame of the European Physical Activity Label for Schools (Eu-PALS, 2020a) project diverse indicators of physical activity, physical education and sport in different European schools have been analysed. As a starting point, this paper is presenting the chosen indicators and comparing them to an already existing physical activity label for schools in Luxembourg. The choice of the quality criteria in the Eu-PALS project, which may lead to the awarding of the label, are further discussed by demonstrating the results of a pilot study at four schools in Luxembourg. This national pilot study shows not only to the participating schools in which areas they might need to improve their activities, but allows also more generally to evaluate the indicators and possibly to improve the choice. Finally, with regard to the topic of the CEREPS Conference 2019 in Prague – “Quality criteria and outcome standards for Physical Education and School Sport” – in the frame of which this study has been presented, it is also discussed whether the project contributes to make criteria and outcome standards of physical education and school sport in Europe visible and comparable.

In 2015, Chou and Orlandi presented an oblivious transfer protocol that already drew a lot of attention both from theorists and practitioners due to its extreme simplicity and high efficiency. Chou and Orlandi claimed that their protocol is universally composable secure (UC-secure) in the random oracle model under dynamic corruptions. UC-security is a very strong security guarantee that assures that, not only the protocol in itself is secure, but can be also used safely in larger protocols. Unfortunately, in this work we point out a flaw in their security proof for the case of a corrupt sender. In more detail, we define a decisional problem and we prove that, if a correct security proof for the Chou and Orlandi's protocol is provided, then this problem can be solved correctly with overwhelming probability. Therefore, the protocol of Chou and Orlandi cannot be instantiated securely with groups for which our decisional problem cannot be solved correctly with overwhelming probability. Consequently, the protocol of Chou and Orlandi cannot be instantiated with {\em all} groups $\G$ in which the CDH problem is intractable, but only with groups in which both the CDH problem is intractable and our decisional problem can be solved with overwhelming probability. After the appearance of our work, Chou and Orlandi acknowledged the problems we pointed out in their security proof and subsequent works showed additional issues, removing the claims of UC security of their protocol.

We consider the problem of recovering the entries of diagonal matrices {U_a}_a for a = 1, . . . , t from multiple “incomplete” samples {W_a}_a of the form W_a = P U_a Q, where P and Q are unknown matrices of low rank. 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.

Research on language contact has so far mainly focused on oral situations, although standardization and language ideologies always have an important influence on multilingualism in both its written and its spoken form. This raises the question of which theoretical models are most suitable for the description of written language contact. The present paper recalls linguistic investigations of written language. Some research on multilingual writing shares concepts with research on oral language contacts, always adapting them for writing. Other research develops new concepts for investigating multilingual writing. Within the framework of research on multilingualism, some concepts approach language contact as a question of systematic interactions between linguistic systems (e.g. borrowing, code-switching, graphe¬mat¬ic matrix, schriftdenken), other concepts envisage language contact as a multilingual practice (e.g. translanguaging, multimodal analysis, biliteracy). Written language contact is an especially fruitful field of study for pointing out major differences between these two research traditions and for bridging them. [less ▲]
