S-matrices for spinor particles on Reissner-Nordstr\"{o}m black holes

The scattering problems arising when considering the contribution of the topologically inequivalent configurations of the spinors on Reissner-Nordstr\"{o}m black holes to the Hawking radiation are correctly stated. The corresponding $S$-matrices are described and presented in the form convenient to numerical computations.Comment: 11 pages, LaTe

Can the general fraud offence 'get the law right'? Some perspectives on the 'problem' of financial crime

The Fraud Bill, which received Royal Assent on 8 November 2006, created an offence of fraud in English criminal law which marks a departure of utmost significance from the approach adopted hitherto, whereby a number of related offences cover behaviour deemed to amount to fraud. To mark the passage of the Fraud Act 2006 into law, this article examines the references which were made during its consideration in Parliament to fraud as activity which is serious and which is often erroneously portrayed as 'victimless' crime. In joining these key criminal policy-making debates with academic study of white-collar crime, it will be suggested that as yet too little attention is being paid to 'ambiguous' popular perceptions of financial crimes for there to be confidence that the fraud offence will, in the words of the current Solicitor-General, 'get the law right'

Business, state, and community: 'responsible risk takers', New Labour, and the governance of corporate business

In December 1998, Peter Mandelson MP, one of the principal architects of the Labour Party’s victory in the May 1997 general election, dramatically resigned as Secretary of State for Trade and Industry. Nevertheless, despite his relatively brief period in that office, Mr. Mandelson left his imprint on policy through the publication in November 1998 of a major White Paper, ‘Our Competitive Future: Building the Knowledge Driven Economy’. The White Paper sets out the New Labour analysis of the national political economy in a globalized world economy and is very much influenced by Mr. Mandelson’s experience of the entrepreneurial spirit during his fact-finding visit to the United States of America. This article seeks to chart the relationship between New Labour’s desire to foster the development of the corporate sector within a vibrant entrepreneurial culture and the need to ensure that the integrity of the market is preserved in an arena which is seen as inimicable to strong regulatory intervention by the state. As well as mapping New Labour’s political rhetoric onto contemporary debates in corporate governance, the analysis will involve an examination of the interface between business practice and morality. In particular, the article will focus upon the role of the conception of company directors as ‘responsible risk takers’ and the upon the use of name-and-shame sanctions in the development of an entrepreneurial culture in which all corporate enterprises are seen as having a legitimate societal ‘licence to operate’

Gauge invariant action at the ultraviolet cutoff

We show that it is possible to formulate a gauge theory starting from a local action at the ultraviolet (UV) momentum cutoff which is BRS invariant. One has to require that fields in the UV action and the fields in the effective action are not the same but related by a local field transformation. The few relevant parameters involved in this transformation (six for the $SU(2)$ gauge theory), are perturbatively fixed by the gauge symmetry.Comment: 5 pages, Latex, no figure

Research on spacecraft electrical power conversion

The steady state characteristics and starting behavior of some widely used self-oscillating magnetically coupled square wave inverters were studied and the development of LC-tuned square wave inverters is reported. An analysis on high amplitude voltage spikes which occur in dc-to-square-wave parallel converters shows the importance of various circuit parameters for inverter design and for the suppression of spikes. A computerized simulation of an inductor energy storage dc-to-dc converter with closed loop regulators and of a preregulating current step-up converter are detailed. Work continued on the computer aided design of two-winding energy storage dc-to-dc converters

Indium adhesion provides quantitative measure of surface cleanliness

Indium tipped probe measures hydrophobic and hydrophilic contaminants on rough and smooth surfaces. The force needed to pull the indium tip, which adheres to a clean surface, away from the surface provides a quantitative measure of cleanliness
