Irradiation Tests at Cryogenic Temperatures on Diffusion Type Diodes for the LHC Superconducting Magnet Protection

Within the framework of the LHC magnet protection system, the irradiation hardness of high current by-pass diodes is subject to examination. The relocation of these diodes and recent calculations give rather low irradiation levels for the position of the diodes. This offers the possibility to replace the originally foreseen epitaxial type diodes by diffusion type diodes. Therefore, different types of 75mm diffusion diodes were submitted to an irradiation test program. One part of the experiments was performed in the Munich Research Reactor. Further irradiation tests were carried out in the northern fixed target area of the SPS accelerator at CERN

Constitutionalising an Overlapping Consensus: The ECJ and the Emergence of a Coordinate Constitutional Order

The European Court of Justice\u27s (ECJ\u27s) jurisprudence of fundamental rights in cases such as Schmidberger and Omega extends the court\u27s jurisdiction in ways that compete with that of Member States in matters of visceral concern. And just as the Member States require a guarantee that the ECJ respect fundamental rights rooted in national tradition, so the ECJ insists that international organisations respect rights constitutive of the EU. The demand of such guarantees reproduces between the ECJ and the international order the kinds of conflicting jurisdictional claims that have shadowed the relation between the ECJ and the courts of the Member States. This article argues that the clash of jurisdiction is being resolved by the formation of a novel order of coordinate constitutionalism in which Member States, the ECJ, the European Court of Human Rights and other international tribunals or organisations agree to defer to one another\u27s decisions, provided those decisions respect mutually agreed essentials. This coordinate order extends constitutionalism beyond its home territory in the nation state through a jurisprudence of mutual monitoring and peer review that carefully builds on national constitutional traditions, but does not create a new, encompassing sovereign entity. The doctrinal instruments by which the plural constitutional orders are, in this way, profoundly linked without being integrated are variants of the familiar Solange principles of the German Constitutional Court, by which each legal order accepts the decisions of the others, even if another decision would have been more consistent with the national constitution tradition, ‘so long as’ those decisions do not systematically violate its own understanding of constitutional essentials. The article presents the coordinate constitutional order being created by this broad application of the Solange doctrine as an instance, and practical development, of what Rawls called an overlapping consensus: agreement on fundamental commitments of principle – those essentials which each order requires the others to respect – does not rest on mutual agreement on any single, comprehensive moral doctrine embracing ideas of human dignity, individuality or the like. It is precisely because the actors of each order acknowledge these persistent differences, and their continuing influence on the interpretation of shared commitments in particular conflicts, that they reserve the right to interpret essential principles, within broad and shared limits, and accord this right to others. The embrace of variants of the Solange principles by many coordinate courts, in obligating each to monitor the others\u27 respect for essentials, creates an institutional mechanism for articulating and adjusting the practical meaning of the overlapping consensus

What's fair? How children assign reward to members of teams with differing causal structures

How do children reward individual members of a team that has just won or lost a game? We know that from pre-school age, children consider agents’ performance when allocating reward. Here we assess whether children can go further and appreciate performance in context: The same pattern of performance can contribute to a team outcome in different ways, depending on the underlying rule framework. Two experiments, with three age groups (4/5-year-olds, 6/7-year-olds, and adults), varied performance of team members, with the same performance patterns considered under three different game rules for winning or losing. These three rules created distinct underlying causal structures (additive, conjunctive, disjunctive), for how individual performance affected the overall team outcome. Even the youngest children differentiated between different game rules in their reward allocations. Rather than only rewarding individual performance, or whether the team won/lost, children were sensitive to the team structure and how players’ performance contributed to the win/loss under each of the three game rules. Not only do young children consider it fair to allocate resources based on merit, but they are also sensitive to the causal structure of the situation which dictates how individual contributions combine to determine the team outcome

The trajectory of counterfactual simulation in development

Young children often struggle to answer the question “what would have happened?” particularly in cases where the adult-like “correct” answer has the same outcome as the event that actually occurred. Previous work has assumed that children fail because they cannot engage in accurate counterfactual simulations. Children have trouble considering what to change and what to keep fixed when comparing counterfactual alternatives to reality. However, most developmental studies on counterfactual reasoning have relied on binary yes/no responses to counterfactual questions about complex narratives and so have only been able to document when these failures occur but not why and how. Here, we investigate counterfactual reasoning in a domain in which specific counterfactual possibilities are very concrete: simple collision interactions. In Experiment 1, we show that 5- to 10-year-old children (recruited from schools and museums in Connecticut) succeed in making predictions but struggle to answer binary counterfactual questions. In Experiment 2, we use a multiple-choice method to allow children to select a specific counterfactual possibility. We find evidence that 4- to 6-year-old children (recruited online from across the United States) do conduct counterfactual simulations, but the counterfactual possibilities younger children consider differ from adult-like reasoning in systematic ways. Experiment 3 provides further evidence that young children engage in simulation rather than using a simpler visual matching strategy. Together, these experiments show that the developmental changes in counterfactual reasoning are not simply a matter of whether children engage in counterfactual simulation but also how they do so.
