    Does the European Union have a reverse gear? Policy dismantling in a hyperconsensual polity

    Get PDF
    The financial crisis has triggered demands to halt and even reverse the expansion of European Union (EU) policies. But have these and previous demands actually resulted in policy dismantling? The existing literature has charted the rise of dismantling discourses such as subsidiarity and better regulation, but has not examined the net effect on the acquis. For the first time, this contribution addresses this gap in the literature through an empirical study of policy change between 1992 and 2014. It is guided by a coding framework which captures the direction of policy change. It reveals that, despite its disposition towards consensualism, the EU has become a new locus of policy dismantling. However, not all policies targeted have been cut; many have stayed the same and some have even expanded. It concludes by identifying new directions for research on a topic that has continually fallen into the analytical blind spot of EU scholars

    GeantV: Results from the prototype of concurrent vector particle transport simulation in HEP

    Full detector simulation was among the largest CPU consumer in all CERN experiment software stacks for the first two runs of the Large Hadron Collider (LHC). In the early 2010's, the projections were that simulation demands would scale linearly with luminosity increase, compensated only partially by an increase of computing resources. The extension of fast simulation approaches to more use cases, covering a larger fraction of the simulation budget, is only part of the solution due to intrinsic precision limitations. The remainder corresponds to speeding-up the simulation software by several factors, which is out of reach using simple optimizations on the current code base. In this context, the GeantV R&D project was launched, aiming to redesign the legacy particle transport codes in order to make them benefit from fine-grained parallelism features such as vectorization, but also from increased code and data locality. This paper presents extensively the results and achievements of this R&D, as well as the conclusions and lessons learnt from the beta prototype.Comment: 34 pages, 26 figures, 24 table

    An integrated view on monitoring and compensation for dynamic optical networks: from management to physical layer

    Get PDF
    A vertical perspective, ranging from management and routing to physical layer options, concerning dynamic network monitoring and compensation of impairments (M&C), is given. Feasibility, reliability, and performance improvements on reconfigurable transparent networks are expected to arise from the consolidated assessment of network management and control specifications, as a more accurate evaluation of available M&C techniques. In the network layer, physical parameters aware algorithms are foreseen to pursue reliable network performance. In the physical layer, some new M&C methods were developed and rating of the state-of-the-art reported in literature is given. Optical monitoring implementation and viability is discussed.Publicad

    Northern Ireland: challenges and opportunities for post-Brexit environmental governance

    Get PDF
    Brexit represents a major change to environmental governance in Northern Ireland and the UK. Yet it is occurring at a time when Northern Ireland has no government, curtailing its ability to engage in both local and UK-wide preparations. Northern Irish stakeholders are worried that tensions between England and Scotland are dominating Brexit preparations, hampering discussions of UK-wide cooperation, as well as of the specific needs of Northern Ireland. They are concerned pre-existing environmental governance issues in the region (such as the lack of an independent environmental agency or the prevalence of cross-border environmental crime) will remain unaddressed, and that current North/South cooperation on environmental issues will be negatively impacted by the Brexit deal. Crucially, the key planks of the UK government’s ‘Green Brexit’ strategy (such as the commitments laid out in the 25 Year Environment Plan and the Environmental Principles and Governance consultation) do not cover the devolved nations. This raises the prospect of further policy divergence and inconsistent implementation and enforcement across the UK, and for Northern Ireland’s environment to continue deteriorating

    Wales: challenges and opportunities for post-Brexit environmental governance

    Get PDF
    Brexit represents a major change to environmental governance in Wales and the United Kingdom (UK), raising both opportunities and challenges. Welsh stakeholders are worried that English interests will predominate in the design of environmental governance after Brexit and are also concerned about the prospect of greater instability and weaker environmental protections. Crucially, the key planks of the UK government’s ‘Green Brexit’ strategy—the 25 Year Environment Plan (25 YEP) and Defra’s environmental governance and principles consultation—do not cover governance in the devolved nations. This gap in coverage raises the prospect of policy divergence and inconsistent implementation and enforcement across the UK. Most importantly, there is a strong fear in Wales that Welsh environmental policy ambition will be thwarted by Brexit and deregulatory pressure emanating from England
