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

Wales: challenges and opportunities for post-Brexit environmental governance
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 governmentâs âGreen Brexitâ strategyâthe 25 Year Environment Plan (25 YEP) and Defraâs environmental governance and principles consultationâdo 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

Scotland: challenges and opportunities for post-Brexit environmental governance
Brexit represents a major change to environmental governance in Scotland and the United Kingdom (UK), raising both opportunities and challenges. It has prompted a constitutional dispute between the Scottish and UK governments, which may jeopardise future environmental governance. The current constitutional impasse has created even more uncertainty, making Brexit preparations highly challenging for government and civil society actors. Scottish 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 governmentâs âGreen Brexitâ strategyâthe 25 Year Environment Plan and the Department for Environment, Food and Rural Affairsâ (Defra) environmental governance and principles consultationâdo 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 Scotland that Scottish environmental policy ambition will be thwarted by Brexit and deregulatory pressure from England

Environmental policy in a devolved United Kingdom: challenges and opportunities after Brexit
The European Union (EU) has had a profound effect on UK environmental policy and governance. The EU provides treaty-based principles to underpin and inform new policy development and a well-developed system of monitoring and enforcement to ensure it is implemented. The EUâs system of environmental governance provides a set of structures that establishes minimum common standards across the UK. These structures have allowed the devolved nations to develop their own policies, some with a higher level of ambition than the UKâs. EU membership, therefore, provides a common framework that enables both transboundary cooperation and local policy innovation.
Brexit consequently represents a major change to environmental governance in the United Kingdom (UK), raising significant opportunities and challenges. Environmental policy in the UK is devolved, but UK devolution is asymmetrical: England has no formal representation or parliament. For environmental policy this means that the Department for Environment, Food and Rural Affairs (Defra) often acts on behalf of England. This model of devolution raises concerns amongst stakeholders in the devolved nations that Defra approaches policy with an English mind-set, which suggests that English interests will dominate after Brexit. There are also concerns that Brexit will lead to greater instability and weaken environmental protections.
In addition, Brexit has prompted a constitutional dispute between the Scottish and UK governments, which may jeopardise future environmental governance. These tensions have created uncertainty, making Brexit preparations highly challenging for both government and civil society actors. Crucially, the key planks of the UK governmentâs âGreen Brexitâ strategyâ the 25 Year Environment Plan (25 YEP) and Defraâs consultation on environmental governance and principlesâdo 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. More importantly, there is a strong fear in Scotland and Wales that their environmental policy ambitions could be thwarted by Brexit and deregulatory pressures emanating from England.
Meanwhile Northern Ireland, which has a history of weak environmental governance and sits alongside the politically sensitive border with Ireland, has no government and therefore no voice in the Brexit negotiations. As a result, it is poorly represented in the discussions over the future shape of UK-wide environmental policy and governance
Northern Ireland: challenges and opportunities for post-Brexit environmental governance
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 governmentâs âGreen Brexitâ 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 Irelandâs environment to continue deteriorating
