The ongoing contact of adolescents with high school staff may provide an opportunity for the early identification and effective management of suicidal behavior. In this study, the knowledge, attitude, and experience of 80 high school professionals regarding adolescent suicide were assessed through semistructured personal interviews. Respondents identified more than 30 signs of potential vulnerability — manifestations of depression, verbal and written cues, isolation, and self-destructive behaviors. Among predisposing factors, those related to alienation within the family were most prominent. Other important risk factors were low self-esteem, difficulty in peer relationships, and economic or ethnic differences from other students. When suicidal behaviors occurred, respondents saw students and staff as attempting to be helpful; families were more often viewed as defensive.  相似文献

A reference standard for gamma-hydroxybutyric acid (GHB) free acid is not commercially available, making its analysis in forensic exhibits more difficult. GHB free acid is typically encountered in aqueous solution and in the presence of the lactone, gamma-butyrolactone (GBL), presenting difficulty in Fourier transform infrared (FT-IR) analysis. The strong infrared (IR) absorptivity of the GBL carbonyl band, the shifting of the GBL carbonyl band in aqueous solutions, and the position of the O-H bend for water can mask the main carbonyl band for GHB free acid. Model solutions of beta-hydroxybutyric acid (BHB) and GBL were studied in order to further understand the masking of the GHB free acid carbonyl band in FT-IR analysis. The use of second derivative FT-IR spectroscopy was shown to provide resolution of the free acid carbonyl band, and a presumptive test for GHB free acid was developed and applied. An extension of this work included preparing, for use as a standard reference material, small amounts (< or = 10 mg) of GHB free acid. Preparation was based on the instantaneous reaction of GHB's sodium salt with a stoichiometric amount of hydrochloric acid in aqueous solution, and subsequent isolation of the free acid in neat liquid form. Both FT-IR and proton nuclear magnetic resonance spectra of the neat reference material were obtained and used to verify its identity. The isolation of GHB free acid from actual forensic exhibits is also presented, with identity confirmation using FT-IR.  相似文献

Penile strangulation with a strand of hair, acting as a tourniquet, and perforation of the eyes with a knife are uncommon accidental injuries in children. In such a situation, a mistreatment must be evoked. We present a case of barbarity and torture involving a young boy 3 years old. He was a victim of penis strangulation and perforation of the eyes, performed on previous surgical and infectious lesions. The mistreatment was performed by his mother's boyfriend. The perpetrator used the previous lesions to hide his misdeed. This amazing case of mistreatment points out the violence of the wounds and their being performed on previous lesions.  相似文献

The Debbie Smith or "Justice for All" Act was passed on November 1, 2004. The act addresses the problem of collecting and analyzing DNA evidence from backlogged rape kits sitting in crime laboratories around the country. Presently, no empirical data exist by which to assess the soundness of the legislation. However, the act clearly affects discrete operations within the forensic and criminal justice systems. This article explores the relative merits of the Debbie Smith law, highlighting changes in Sexual Assault Nurse Examiner (SANE) programs, law enforcement, court administration, correctional treatment, and juvenile justice practices. Concerns linked to the likely impact of the "Justice for All" Act raise significant questions about its overall programmatic utility and treatment efficacy.  相似文献

The authors propose the method of total isolation of the hypothalamic-hypophyseal system for more effective study of causes of death in craniocerebral injury and pathology in expert practice. The method can be also applied for making an anatomic preparation of the brain and hypophysis in teaching anatomy.  相似文献

The authors describe principles, methods and staging of molecular-genetic identification of hostages killed in the Beslan terroristic act. Cases when it was impossible to identify person definitely are explained. Precise staging of the expert investigation is of key importance.  相似文献
