V751 Cyg and V Sge as transient supersoft X-ray sources

I review the observational evidence for luminous, soft X-ray emission during optical low-states in the two cataclysmic variables V751 Cyg and V Sge, and discuss the possible link to the canonical supersoft X-ray sources.Comment: 6 pages with newarcrc.sty; inv. talk given at the 60th birthday Symp. in honour of Brian Warner, Oxford, April 1999, to appear in New Astronomy Reviews (Elsevier), eds.

Estimating the small area effects of austerity measures in the UK

Governments across Europe are starting to implement a range of cost-cutting and income generating programmes in order to re-balance their fiscal budgets following substantial investments in stabilising domestic financial institutions in 2008 and 2009. One method of doing this has been to increase tax rates such as the increase in VAT in the UK from 17.5% to 20% from January 1st 2011. In this paper we explore the different spatial impact of this VAT rise on household expenditure on public and private transport and communication technology from 2006 to 2016. We do this by combining three elements: an agent-based dynamic population microsimulation model that produces projected snapshots of the UK population in 2006, 2011 and 2016; an expenditure system model based on the familiar Quadratic Almost Ideal Demand System approach; and synthetic small area census tables produced by projecting historical UK census data. Taken together these elements provide a toolkit for assessing the potential spatial impact of rising taxes or prices (or both) and we use them to compare small area projections of household expenditure under two scenarios. The first is a 'no intervention' scenario where prices and income align to UK government inflation forecasts and the second is a one-off non-reversed 2.5% increase in VAT on goods and services rated at 17.5% on 1st January 2011. We present results for different areas (rural vs urban/deprived vs affluent) and for different income groups within them and discuss the potential implications for the telecommunications industry and for the usage of public and private transport

Implications for the U.S. of Anglo-French Defense Cooperation

The paper analyzes, from a predominantly UK perspective, the implications for the U.S. of the November 2, 2010, Anglo-French Defence Cooperation Treaty. The current pressures on British and French defence budgets were the primary driving force behind this cooperative effort. London and Paris have made steps toward improving joint efforts in a number of areas, with defence acquisition and industrial cooperation being prominent. In the UK, there appears to be strong political support at the highest levels, which has permeated to lower levels in the bureaucracy, while the UK defence industry appears to be cautiously optimistic about future business opportunities. The impact of enhanced Anglo-French cooperation on the U.S. would appear to be largely favourable for Washington. Rather than providing a basis for weakened UK attention to the U.S., as some fear, the efforts by London and Paris will potentially generate greater national military capability from scarce resources and could serve as a vehicle for broader European efforts to enhance their defence capabilities. While multinational European military development projects are viewed with scepticism in the UK, the Anglo-French arrangement could strengthen the prospects for bilateral projects in which other European states may elect to participate

International constitutionalism and the state : a rejoinder to Vlad Perju.

The transplantation of a legal governance form from one order to another is always fraught with difficulty. Perju’s Reply asks critical questions regarding the characterization of future global governance and most particularly the use of constitutionalism beyond the state presented in my article. Perju argues that an a priori matter, whether constitutionalism is suitable beyond the state, is of critical import. My original article centered upon a “what if” question, what would the impact of an international constitutionalization process be upon the state and whether this would be an advantageous process, what Perju portrays as “the very option” of constitutionalism. The sense of urgency which Perju finds apparent in my article is also perceptible in other recent attempts to offer options for the future of the global legal order. Alongside constitutionalization, other narratives ranging from global legal pluralism to global administrative law form part of a much broader narrative of “what if” questions within international governance debates seeking to consider what exists beyond the classical state consent tropes discussed in the article. This rejoinder focuses upon several questions raised by Perju: transplantation, multiple constitutional orders, and the link between normative and structural constitutionalism.1 First, transplantation and the applicability of constitutionalism, as part of a process of constitutionalization, beyond the state. Walker considers that the opposition to constitutionalism beyond the state relies upon four interrelated categories: inappropriateness, inconceivability, improbability, and illegitimacy.2 Inappropriateness is linked to what Perju states as taking “for granted the existence of an international legal order.” Indeed, the constitutionalization debate and my article assume that a legal order exists beyond the state. Whilst not embracing Peters’s claim that constitutionalization acts as a bulwark against assertions of international law’s limitations as a legitimate legal order nor wishing to dismiss outright those that do question international law’s legitimacy,

Anglo-French defence cooperation in the age of austerity

This paper seeks to assess, from a predominantly UK perspective, the potential benefits of enhanced Anglo-French defence cooperation, not only to the two countries concerned but also to Western Europe and the USA. The paper will mainly focus on defence cooperation and not the subordinate agreement regarding limited cooperation on nuclear weapons, which addressed cooperation on the safety and security of nuclear weapons, stockpile certification and countering nuclear and radiological terrorism but seemed to be driven by "acute financial pressures, symptomatic of severe structural deficiencies"
