This study aimed to expand the scope of previous research by assessing the effectiveness of soot-removal techniques on glass from petrol-bomb debris using methods of 1% and 2% sodium hydroxide (NaOH) solutions, ultrasonic bath and vacuum suction. Of particular interest were the 1% and 2% NaOH solutions applied to the soot-covered surfaces. Petrol bombs containing petrol or a 50:50 mix of petrol and motor oil were exploded and the debris was collected for analysis. Favourable results were found to varying degrees using each of the soot-removal methods with the 1% and 2% NaOH wash solutions, being the most useful. The 2% NaOH solution also proved successful as a soak to loosen and remove heavy contamination of soot and accelerants without damaging the finger mark beneath. This study also found that recovery of finger marks in blood from beneath soot using the 2% NaOH solution was possible. Finger marks were also applied to glass bottles with plastic adhesive labels, and providing the fire damage is not too great marks were also retrievable. Results from this study lead to the conclusion that the NaOH wash solution is ideally suited for soot removal to reveal latent and blood-contaminated marks both within the laboratory and at crime scenes. 相似文献

The implementation of a dispersal policy in Britain has broughtasylum seekers to regions of the country which previously hadlittle experience of providing services for this group. Around10,000 asylum seekers have been resettled in the city of Glasgowsince 2000 as a result of the policy. Multi-agency networkshave been established in Glasgow as a medium for facilitatingco-operation across the voluntary and statutory sectors forthe provision of locally-based support services, while alsofacilitating community development. This paper explores theexperiences of these networks since their inception. While highlightingthe continuing importance of the voluntary sector in supportingasylum seekers and refugees, it raises concerns over the reactiveway in which services have been provided, where responsibilityhas fallen on voluntary and community organizations to fillgaps in statutory service provision. It further examines theimplications for social cohesion of housing-led resettlement,which has largely been in areas suffering from social deprivation.The findings highlight the frustrations of service providersworking within a disjointed policy framework, characterizedby contradictions between Scottish and UK policy goals. 相似文献

California is now in its 11th year of mandatory child custody mediation, with a current yearly case volume statewide estimated at 65,494. This article profiles the variations in programs and mediation styles in 56 of the state's 58 Superior Courts. Two research studies provide the basis for the information on program structures, case activity, procedures, agreement formats, recommendations, facilities, security, and fees. 相似文献

Correctional facilities are increasingly burdened with mentally disordered offenders and are faced with the formidable task of effectively screening inmates for major mental disorders and suicide potential. Teplin and Swartz (1989) developed the Referral Decision Scale (RDS) as a rapid screen for schizophrenia and major mood disorders in jail populations. However, more recent research by Hart, Roesch, Corrado, and Cox (1993) has called into question the effectiveness of the RDS. In this study, we examined the convergent and discriminant validity of the RDS with the Schedule of Affective Disorders and Schizophrenia—Change Version (SADS-C) and the Personality Assessment Inventory (PAI) on a sample of 108 mentally disordered inmates. The RDS provided moderate evidence of convergent validity but failed to demonstrate acceptable discriminant validity, because of high intercorrelations on RDS subscales (heterotrait-monomethod coefficients). In comparison, the SADS-C yielded similar evidence of convergent validity and excellent discriminant validity.The authors would like to thank the Research Opportunities Program, University of North Texas for its grant support and Captain James Moore for his active cooperation.Tarrant County Mental Health and Mental Retardation Services. 相似文献

Mandatory reporting legislation has been adopted in every state to insure the protection of children from maltreatment. These statutes have become a significant factor in the lives of mental health professionals who work with children and families. Thirty psychotherapists who had made a recent report of child maltreatment on a client in treatment were interviewed about their experiences with reporting and the consequences of reporting for therapeutic relationships. Several potentially problematic consequences and dilemmas were identified by the therapists, including immediate and long-term effects on the therapeutic alliance and course of therapy, and conflicts of interest in working with children and families. 相似文献
