Les procédures d’insolvabilité présentent de plus en plus fréquemment une dimension européenne qui fait naître nombre de questions particulières. Quelles sont les juridictions compétentes pour ouvrir une procédure d’insolvabilité et quelle loi doivent-elles appliquer ? Comment assurer l’égalité entre les créanciers dans quelque État membre qu’ils se trouvent ? Comment protéger ceux qui sont titulaires de sûretés réelles portant sur des biens situés à l’étranger ? Comment prendre en compte l’appartenance du débiteur à un groupe de sociétés? Depuis le 26 juin 2017, ces questions sont régies par le Règlement n° 2015/848 du 20 mai 2015, qui modifie nombre des solutions en vigueur sous l’empire de l’ancien Règlement n° 1346/2000 du 29 mai 2000. Cet ouvrage s’adresse à tous les praticiens et universitaires intéressés par le droit européen de l’insolvabilité. En plus d’exposer les solutions issues du Règlement ou de la jurisprudence européenne, il met en exergue, le cas échéant, l’interprétation de ces solutions par la jurisprudence et la doctrine de différents États membres.

The phenomenon of non-mediation is an important factor in virtual experiences. Users seem to ignore their physical surroundings and become present in the virtual environment (VE). Assessing presence in VEs with continuous measures is an ongoing effort both to complement the data provided by self-report measures and to identify specific events during virtual experiences that disrupt presence (“breaks in presence”; BIPs, Slater & Steed, 2002). Early studies employed self-report measures for BIPs, but have also identified specific psychophysiological reactions bearing the potential to develop a continuous measure—the nature of these reactions, however, has been unclear. We argue that BIPs can be considered as orienting responses (ORs; Sokolov, 1963) as users interact with VEs based on dedicated mental models and direct all their attention to virtual stimuli. When a new virtual stimulus is incompatible with these mental models, an OR is triggered, directing user attention at the source of the stimulus to determine its cause. ORs have been linked to psychophysiological reactions (Bradley, 2009) similar to the ones reported for BIPs. We designed a series of three studies to investigate this account to BIPs. Two studies are already complete, while a third study is currently being conducted. In all studies, users played Skyrim (Bethesda, 2011) modified to include stimuli that can be considered as BIPs not belonging to the VE. We measured psychophysiological responses using ECG and GSR. In study 1 (N = 31) participants played for M = 82.08 minutes (SD = 34.23) and encountered ten different types of BIP stimuli (e.g. error message, game crash) determined empirically through a prestudy. In line with previous literature on ORs, we found significant responses in ECG and GSR for all BIPs with a clearly defined stimulus onset. Additionally, we found a habituation effect of repeated exposure to the error message consistent with habituation of orienting. Analysis of blinking activity showed prolonged intervals during BIPs consistent with the information acquisition function of ORs. In study 2 (N = 69) participants played for M = 22.02 minutes (SD = 7.1). We employed a modified secondary-task reaction time (STRT) procedure in addition to psychophysiological measurements to compare ORs towards a game-related stimulus with ORs towards a BIP-stimulus. By pressing a footswitch, participants had to react to a crying baby, embedded into the game’s narrative, or a similarly pitched interference pattern of two sinewaves. Although we expected faster reaction times for game-related stimuli, we found similar reaction times for both types of stimuli. However, we could replicate the psychophysiological patterns from study 1. Both sounds equally elicited ORs with game-related stimuli leading to stronger responses and habituation. The data from the first two studies indicate that BIPs can be considered a type of OR, suggesting a promising avenue towards continuous measurement of presence. Following a similar design, Study 3 employs a STRT task based on more intricate considerations of the processes in human working memory (Oberauer, 2009). Additionally, pupil dilation is being assessed to investigate cognitive load associated with responses to game-related stimuli and BIPs. [less ▲]

The Confédération Fiscale Européenne welcomes the clarification of the notion of selectivity in the World Duty Free Group decision. It is now clear that a tax measure that derogates from the normal tax scheme can constitute State aid even if the tax measure appears to be general in nature and does not lead to a benefit for a specific predefined group of undertakings. Given the variety of tax rules in each Member State, however, further clarification on the determination of the reference framework, the comparability test and the scope of potential justifications will be necessary.

The debate on the sustainability of the European model(s) is becoming increasingly urgent. The multidimensional crisis that has been felt across the world since 2007 has revealed a deep need to raise awareness of the important social aspect of European integration. This paper aims to provide a critical assessment of how the crisis and austerity measures have affected the protection of fundamental social rights in the euro area. The paper argues that the continued success and the sustainability of the European project largely depends on a renewed emphasis on its social dimension [less ▲]

One lesson afforded by the recent economic and financial crisis is the need to recreate a process of convergence among Member States and within societies, with productivity, job creation and social fairness at its core. The paper looks at how the initiative for a European Pillar of Social Rights contributes to the sustainability of socio-economic rights, offers a comparison with existing social rights protection instruments and examines its added value. It argues that there is also room for greater convergence and complementarity between the various systems established to protect fundamental social rights in Europe. [less ▲]

Breaks in presence are considered a promising approach to investigate events where users are pulled out of their virtual experiences. In this paper, we argue that this methodology may also provide insights into the cognitive processes behind the presence experience. To this end, we combined breaks in presence with a modified version of the secondary task reaction times paradigm and psychophysiological measures to tap into the attentional processes behind presence experiences. 69 participants played a modified video game, during which they had to react to sounds that were either part of the story or unrelated (breaks in presence) as a secondary task. We measured their reaction times to both sound types, skin conductance responses and heart rate variability. Participants reacted equally fast to virtual and BIP-eliciting stimuli. Both types of stimuli elicit orienting responses with our virtual stimulus leading to stronger responses and habitualization. Avenues for future research are discussed. [less ▲]

The initiative for a European pillar of social rights launched by Jean Claude Juncker is expected to serve as a "compass" for the renewed convergence within the euro area. Social rights are therefore returning to centre stage as part of a deeper, fairer Economic and Monetary Union. Against this backdrop, this paper analyses the role and effectiveness of these fundamental rights as instruments in the service of the new European economic governance. [less ▲]

The Confédération Fiscale Européenne welcomes the precise and instructive decision in SECIL. The decision clarifies the application of article 63 of the TFEU on the free movement of capital to tax legislation that denies tax benefits to dividends originating in non-EU Member States and demonstrates that Member States may not rely on article 64(1) of the TFEU, i.e. the “grandfathering clause”, if the logic of their tax legislation changed after 31 December 1993, which change can also be brought about through the conclusion of directly applicable international agreements (for example, Euro-Mediterranean Agreements). The Confédération Fiscale Européenne appreciates the further clarification that provisions with direct effect in EU international agreements with third countries, such as the Euro-Mediterranean Agreements, can create economic rights that can be relied upon by taxpayers.
