This paper presented results from a details and comprehensive simulation using finite element method of the practical operation of an electrical machine. The results it displayed have been used in practice to design more efficient equipment.

Investigating the cost Performance of UK Credit Unions using Radial and Non-Radial Efficiency Measures

This paper examines the relative efficiency of UK credit unions. Radial and non-radial measures of input cost efficiency plus associated scale efficiency measures are computed for a selection of input output specifications. Both measures highlighted that UK credit unions have considerable scope for efficiency gains. It was mooted that the documented high levels of inefficiency may be indicative of the fact that credit unions, based on clearly defined and non-overlapping common bonds, are not in competition with each other for market share. Credit unions were also highlighted as suffering from a considerable degree of scale inefficiency with the majority of scale inefficient credit unions subject to decreasing returns to scale. The latter aspect highlights that the UK Government's goal of larger credit unions must be accompanied by greater regulatory freedom if inefficiency is to be avoided. One of the advantages of computing non-radial measures is that an insight into potential over- or under-expenditure on specific inputs can be obtained through a comparison of the non-radial measure of efficiency with the associated radial measure. Two interesting findings emerged, the first that UK credit unions over-spend on dividend payments and the second that they under-spend on labour costs.

No War, No Peace: Northern Ireland after the Agreement

In 1998 a historic agreement, commonly known as the Belfast or Good Friday Agreement, formed the basis of a negotiated settlement for the future of Northern Ireland. Since that time the level of violence in Northern Ireland has reduced but many problematic issues related to governance, sectarianism, and community relations remain on the political agenda and have destabilized the post-peace accord environment. Many of these issues can be viewed as either causes or consequences of the protracted conflict in Northern Ireland. This special issue examines some of these issues from a political psychology perspective. Economic, political, social, and psychological factors that have supported and hindered progress towards peace and stability are considered. While the paramilitary ceasefires have remained intact and certain aspects of life in Northern Ireland have been transformed, the road to peace has been hindered by both political and psychological intransigence. This paper offers an opportunity to reevaluate conceptualisations of conflict and its management in chronic situations, where divisions are deeply embedded within societal structures and relationships, and consider factors that may act as barriers to the development of a lasting peace.

A panel of single locus minisatellite DNA probes for application to problems in salmonid aquaculture

Eleven minisatellite DNA locus specific probes, isolated from Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) partial genomic DNA libraries, were tested for cross-hybridization to eleven other salmonid species, i.e. sockeye salmon (Oncorhynchus nerka); coho salmon (O. kisutch), chum salmon (O. keta); pink salmon (O. gorbuscha); chinook salmon (O. tshawytscha); rainbow trout (O. mykiss); brook trout (Salvelinus fontinalis); Arctic charr (S. alpinus); grayling (Thymallus thymallus); huchen (Hucho hucho); pollan (Coregonus autumnalis). Simple single locus profiles for each of these species were revealed by, from two to ten SLPs. These markers are likely to be of great value in addressing several problems in aquaculture of these species.
