“Megan’s Law” in the United States and Part 1 of the Sex Offenders Act 1997 in the United Kingdom, make provision for the creation of a register which will record the names and addresses of all persons convicted or cautioned for a sexual offence. Arguments expounded in favour of the legislation include the supposedly high recidivism among sex offenders, the inadequacy of supervision provisions, and the resulting need to ‘track’ the dangerous offender for public protection. In practice, however, there are a plethora of obstacles, such as cost and inadequate policing resources, which may impede its effectiveness in aiding law enforcement and reduce it to symbolic significance only. In addition, there are an array of ethical objections to the legislation, such as it breaches civil liberties and constitutes ‘double jeopardy’, which may prevent meaningful imposition.

The aim of this paper is to explore the implications and difficulties of a system of sex offender registration for Northern Ireland and the Republic of Ireland. From the orthodox perspective, registration appears justified. Sexual offending has increased and this is used by the media to generate a ‘moral panic’. However, sexual offenders in the community have also been socially constructed in Ireland, as a problem requiring specific action, through Blumer’s (1971) developmental perspective. It is this perspective which most adequately explains the formulation of the legislation. Arguments expounded in favour of registration include the supposedly high recidivism among sex offenders, the inadequacy of supervision provisions and the resulting need to ‘track’ the offender for public protection. Yet, in practice there are a plethora of obstacles such as cost and inadequate policing resources, not considered at the time the legislation was being formulated, which may impede its effectiveness in aiding law enforcement and reduce it to symbolic significance only. Given these difficulties, it is argued that registration is not an appropriate response to the problem of released sexual offenders in Ireland. Rather, from the social constructionist perspective, it is suggested that it is better to ‘treat’ the sex offender through less formal and stringent means in the community away from the criminal justice process.

Early local invasion by astrocytoma. cells results in tumor recurrence even after apparent total surgical resection, leading to the poor prognosis associated with malignant astrocytomas. Proteolytic enzymes have been implicated in facilitating tumor cell invasion and the current study was designed to characterize the expression of the cysteine proteinase cathepsin S (CatS) in astrocytomas and examine its potential role in invasion. Immunohistochemical analysis of biopsies demonstrated that CatS was expressed in astrocytoma cells but absent from normal astrocytes, oligodendrocytes, neurones and endothelial cells. Microglial cells and macrophages were also positive. Assays of specific activity in 59 astrocytoma biopsies confirmed CatS expression and in addition demonstrated that the highest levels of activity were expressed in grade IV tumors. CatS activity was also present in astrocytoma cells in vitro and the extracellular levels of activity were highest in cultures derived from grade IV tumors. In vitro invasion assays were carried out using the U251MG cell line and the invasion rate was reduced by up to 61% in the presence of the selective CatS inhibitor 4-Morpholineurea-LeuHomoPhe-vinylsulphone. We conclude that CatS expression is up-regulated in astrocytoma. cells and provide evidence for a potential role for CatS in invasion.

This article focuses on the experiences of 7-8 year old working-class girls in Belfast, Northern Ireland and their attitudes towards education. It shows how their emerging identities tend to emphasize relationships, marriage and motherhood at the expense of a concern with education and future careers. The article suggests that one important factor that can help explain this is the influence of the local neighbourhood. In drawing upon Bourdieu's concepts of symbolic violence and habitus and Elias' notion of figuration, the article shows how the local neighbourhood represents the parameters of the girls' social worlds. It provides the context within which the girls tend to focus on social relations within their community and particularly on family relationships, marriage and children. It also provides the context within which the girls tend to develop strong interdependent relationships with their mothers that also tend to encourage and reinforce the girls' particular gendered identities. The article concludes by arguing that there is a need for more research on working-class girls and education to look beyond the school to incorporate, more fully, an understanding of the influence of the family and local neighbourhood on their attitudes towards education and their future career aspirations.

Karyotyping of Fasciola hepatica samples from Britain and Ireland has identified a triploid isolate which is effectively aspermic, rendering it necessarily asexually reproducing. Considering the extensive presence of asexually reproducing diploid and triploid Fasciola in Asia it is suggested that facultative gynogenesis is widespread in this parasite. This has important implications for the population genetics and evolution of Fasciola, especially in relation to the development and spread of drug resistance, and must be considered in the mathematical modelling of this process.

It is necessary to understand how state borders in Europe are changing in order to fully assess the factors which facilitate and encourage cross-border cooperation. This article considers the enduring social significance of borders, the need for a historical understanding of the nature and extent of border change in Europe, and the impact of recent European integration. Change in the structure, functions and meanings of European state borders has been the norm rather than the exception. Although much of this change has been associated with war, violence and coercion, a key contemporary issue facing the architects of European integration is how the ambiguity and contradictory nature border change can be regulated democratically and managed cooperatively.
