Adolescent Substance abuse among young people excluded from school in Belfast

The lifestyles of young people excluded from school have received much attention recently, particularly in relation to illicit drug use. Commentators have acknowledged that they constitute a high-risk group to social disaffection and substance abuse. This paper reports on a group of 48 young people living in Belfast aged 13�14 years who are considered to be at a particularly high risk to substance abuse because they are excluded from school. The evidence in this paper suggests that many are already exhibiting potentially high-risk behaviours to problem drug use compared with their contemporaries in mainstream education. This paper examines the evidence within the context of a limited existing literature base on this group of young people. It suggests that a more focused approach is required for the development of appropriate drug-prevention strategies to meet their needs.

Diagnosing child sex abuse: A research challenge.

Child sex abuse increasingly is recognised as a societal problem that can no longer be ignored. In this paper definitions, prevalence, trends, assessment, and available diagnostic procedures are described and critically evaluated. It is argued that the lack of reliable diagnostic procedures remains one of the main difficulties in dealing effectively with the detrimental effects of CSA on the child or adult. The research challenge to find effective alternative procedures is outlined.

Exploring the Views of Police Officers on the Use of Video Taped Evidence in Child Abuse Cases in Northern Ireland

This paper sets out to explore the views and attitudes of police officers in the Greater Belfast area, concerning the process and use of video taped interviews with child witnesses, subsequently used as court evidence in child abuse cases. The information was collected by means of a postal questionnaire, completed by police officers who had all experienced joint interviews with social workers of child witnesses. With the increased use of video evidence as an alternative to the distressing experience of a child appearing in court to give evidence, the research findings and conclusions provide clear messages about future developments both nationally and internationally.

Use of a rotating disc reactor to investigate the heterogeneously catalysed oxidation of cinnamyl alcohol in toluene and ionic liquids

To evaluate the effect of mass transfer limitations in the three-phase oxidation of cinnamyl alcohol carried out in toluene and an ionic liquid (1-butyl-3-methyl-imidazolium bis(trifluoromethylsulphonyl)imide), studies have been performed in a rotating disc reactor and compared with those carried out in a stirred tank reactor where mass transfer effects are considered negligible. High catalyst efficiencies are found in the stirred tank reactor with the use of both ionic liquid and toluene, although there is a decrease in rate for the ionic liquid reactions. In contrast, internal pore diffusion limits the reaction in both solvents in the rotating disc reactor. This mass transfer resistance reduces the problem of overoxidation of the metal surface when the reaction is carried out in toluene, leading to significantly higher rates of reaction than expected, although at the cost of decreased selectivity.
