Network Neutrality: A Research Guide

The conclusion in a research handbook should emphasise the complexity of the problem than trying to claim a one-size-fits-all solution. I have categorised net neutrality into positive and negative (content discrimination) net neutrality indicating the latter as potentially harmful. Blocking content without informing customers appropriately is wrong: if it says ‘Internet service’, it should offer an open Internet (alongside walled gardens if that is expressly advertised as such). The issue of uncontrolled Internet flows versus engineered solutions is central to the question of a ‘free’ versus regulated Internet. A consumer- and citizen-orientated intervention depends on passing regulations to prevent unregulated nontransparent controls exerted over traffic via DPI equipment, whether imposed by ISPs for financial advantage or by governments eager to use this new technology to filter, censor and enforce copyright against their citizens. Unraveling the previous ISP limited liability regime risks removing the efficiency of that approach in permitting the free flow of information for economic and social advantage. These conclusions support a light-touch regulatory regime involving reporting requirements and co-regulation with, as far as is possible, market-based solutions. Solutions may be international as well as local, and international coordination of best practice and knowledge will enable national regulators to keep up with the technology ‘arms race’

European Law and Regulation of Mobile Net Neutrality

Mobile is a rapidly growing and potentially major element of the future Internet, and its environment cannot be sensibly considered in isolation from fixed networks [2]. A note on terminology: Europe uses the term Mobile Network Operators (MNOs) while the United States uses 'wireless' Internet Service Providers (ISPs) [3]. 'Wireless' is somewhat more open in the United States. In Europe, mobile has always made special pleading for forms of self-regulation, as we will see. The article introduces mobile broadband, then considers net neutrality in the fixed environment including the new laws passed in November 2009 in the European Parliament, before considering the mobile net neutrality debate, the degree of price control regulation exerted on European mobiles and the MNOs' vigorous rear-guard anti-regulation defence. Finally, I look at the effects of this regulatory asymmetry and whether MNO calls for mobile to be treated differently from other ISPs can be justified. I conclude by examining what the effect of price and content control on mobile is likely to be for incentives for fixed ISPs and produce a result that I describe as the 'fixed' strategy

Analysis of the retail survey of products that carry welfare- claims and of non-retailer led assurance schemes whose logos accompany welfare-claims.

This report serves two aims. Firstly, this report contains analysis of the retail audit (sub-deliverable 1.2.2.1) of welfare-friendly food products in the 6 study countries. The report gives the results of an emerging comparative analysis of the ‘market’ for welfare-friendly food products in the 6 study countries. It also outlines ‘non-retailer’ led schemes1 whose products occurred in the study. In this way, an emerging picture of the actual product ranges, that make claims about welfare-friendliness, will be drawn based on fieldwork carried out from November 2004 until April 2005. Also, the report explores how the different legislative and voluntary standards on animal welfare compare across different countries and how these actively advertise their welfare-friendlier component to consumers through food packaging. <br/

Feeding Britain: Food Security after Brexit

This Food Brexit Briefing brings together three interlinked issues that demand policy attention as the clock ticks towards Brexit: 1. The question of whether the Government is paying enough attention to agri-food in the negotiating process, given its central role in both public wellbeing and the national economy. 2. The threat a careless Brexit poses to the UK’s short-term food security – and any long-term attempt to develop a genuinely sustainable food strategy for the whole of the UK. 3. The risk generated to the UK’s status as a potential trading partner of the EU by the Food Standards Agency’s decision to press ahead with major reform of UK food safety regulation, at a time when regulatory stability and clarity have never been more important. The report was written by FRC’s Professor Tim Lang, with Professor Erik Millstone (Sussex), Tony Lewis (Head of Policy at Chartered Institute for Environmental Health) and Professor Terry Marsden (Cardiff). It takes stock of ‘food Brexit’ and argues that a hard Brexit or no-deal Brexit (and retreat to WTO rules) would imperil the sustainability and security of Britain’s food supply. The report recommends that the Government should: - Maintain a clear and explicit focus on the potential adverse effects of Brexit on food security in the UK, while negotiating the UK’s future trading relationships with the EU and other jurisdictions. - Publish Brexit impact studies on the UK’s agricultural and food system for the White Paper and Chequers Statement and any subsequent proposals. - Ensure that high food standards remain at the heart of any future trade deals. - Provide clarity on its proposed migration policy, taking account of the contributions that non-UK citizens of the EU are making to the quantity and quality of the UK’s food supply and services. - Avoid a hard Food Brexit at all costs.The UK must not retreat to a WTO-rules-based regime. The EU would then categorise the UK as a ‘3rd Country’, which could be a recipe for chaos. - Create a new Sustainable Food Security Strategy. This would engage with the complexities of the food system and the multiple criteria by which it should be evaluated; and identify clear priorities and pathways for progress. The report also calls on the Food Standards Agency to: - Address the calls for clarification and evidence posed in the paper in respect of its Regulating Our Future (ROF) Where such clarification or evidence is not available, then the Agency should modify or suspend the introduction of its proposals, at least until after Brexit

Cartan-Hannay-Berry Phases and Symmetry

We give a systematic treatment of the treatment of the classical Hannay-Berry phases for mechanical systems in terms of the holonomy of naturally constructed connections on bundles associated to the system. We make the costructions using symmetry and reduction and, for moving systems, we use the Cartan connection. These ideas are woven with the idea of Montgomery [1988] on the averaging of connections to produce the Hannay-Berry connection

The retail of welfare-friendly products: A comparative assessment of the nature of the market for welfare-friendly products in six European Countries

This paper attempts to describe the market for welfare-friendly foodstuffs within larger retailing trends in six study countries in Europe (Norway, Sweden, Italy, France, the Netherlands and the UK). This is based on the findings to date from the work carried out by the work package 1.2 whose aims are to study the current and potential market for welfare-friendly foodstuffs. The aims of the current empirical stages of work package 1.2 are focussed on – what do retailers communicate to consumers about animal welfare? How is animal welfare framed? Are welfare-claims used on their own or within broader issues of quality

Reduction, Symmetry and Phases in Mechanics

Various holonomy phenomena are shown to be instances of the reconstruction procedure for mechanical systems with symmetry. We systematically exploit this point of view for fixed systems (for example with controls on the internal, or reduced, variables) and for slowly moving systems in an adiabatic context. For the latter, we obtain the phases as the holonomy for a connection which synthesizes the Cartan connection for moving mechanical systems with the Hannay-Berry connection for integrable systems. This synthesis allows one to treat in a natural way examples like the ball in the slowly rotating hoop and also non-integrable mechanical systems

The geometry and analysis of the averaged Euler equations and a new diffeomorphism group

We present a geometric analysis of the incompressible averaged Euler equations for an ideal inviscid fluid. We show that solutions of these equations are geodesics on the volume-preserving diffeomorphism group of a new weak right invariant pseudo metric. We prove that for precompact open subsets of ${\mathbb R}^n$, this system of PDEs with Dirichlet boundary conditions are well-posed for initial data in the Hilbert space $H^s$, $s>n/2+1$. We then use a nonlinear Trotter product formula to prove that solutions of the averaged Euler equations are a regular limit of solutions to the averaged Navier-Stokes equations in the limit of zero viscosity. This system of PDEs is also the model for second-grade non-Newtonian fluids
