Eighty-nine adult female survivors of childhood sexual abuse, presenting for psychological treatment, were assessed for self-reported rates of self-injurious behaviors (SIB), health complaints, and posttraumatic stress disorder (PTSD) symptoms of physiological arousal. A composite measure of current SIB was significantly and positively associated with health complaints, PTSD arousal, and three measures of sexual abuse severity: age of onset for sexual abuse, injury experienced during the sexual abuse, and perceived life threat. Tests of mediation revealed that symptoms of PTSD arousal mediated the relationship between earlier age of onset for sexual abuse and SIB. PTSD arousal moderated the relationship between sexual-abuse-related injury and SIB. SIB was a unique predictor of health complaints, even after controlling for sexual abuse severity and PTSD arousal.  相似文献

The Asia-Europe Meeting (ASEM) framework was created in 1996, with the primary purpose of strengthening economic, political and cultural relations among the 15 countries of the European Union and ten East Asian states. This paper examines the origins of these recent economic linkages, in a global and inter-regional context.¶The paper charts the principal elements of ASEMs economic pillar to date, assesses the influence of multilateral trading environments (notably the WTO) on the region-to-region dialogue and examines ASEMs impact on intra-regional economic developments, especially in the case of East Asia.¶The paper will focus in particular on the flagship projects of trade and investment facilitation, to discuss whether and to what extent ASEM itself can be seen to further cooperation and coordination in specific fields of activity.¶The final part of the paper aims to analyse the prospects for future economic relations between East Asia and Europe, in the wake of a devastating financial crisis in Asia, in the context of a continued war on terror which, since the Bali bombing has had an even more immediate impact on Asia, and in the changing global economic environment as regulated by the tenets of the WTO.  相似文献

The analytic accuracy and precision for measurement of chemical analytes in vitreous humor (VH) are critical if results are to be used in forensic pathology. The purpose of our study was to demonstrate the stability and the reproducibility of VH sodium, potassium, chloride, glucose, urea nitrogen, acetone, and beta-hydroxybutyrate in specimens obtained from both eyes in medical examiner cases. We also compared with calculated VH osmolalities. Small but significant increases were observed in VH electrolyte concentrations in specimens refrigerated 6-12 months: sodium pre 144 mmol/L, post 151 mmol/L; potassium pre 12.0 mmol/L, post 12.8 mmol/L; chloride pre 121 mmol/L, post 123 mmol/L. No differences were observed between eyes, and within-day precision for all electrolyte measurements were excellent, (<1%). Frozen specimens showed significantly higher measured (439 mOsmol/kg) as compared with calculated osmolality (305 mOsmol/kg), with 1% within-day precision and no significance between eye variation for glucose and urea nitrogen. In 20 of 24 medical cases selected for possible ketoacidosis, measurement of beta-hydroxybutyrate concentrations appears to be a promising diagnostic biomarker for confirming suspected ketosis in medical examiner cases by means of VH analysis.  相似文献

Five variables were investigated in the evaluation of Suicide Prevention Weeks (SPW) held in 1999, 2000, and 2001 in Québec, Canada: exposure to the campaign, previous suicide ideation, knowledge, attitudes, and intentions. After the year 2000 campaign, a telephone survey conducted on a representative sample of 1020 men revealed that only those actually exposed to the SPW had gained more knowledge of suicide facts and resources. However, the SPW did not influence attitudes or intentions to seek help. Results are not surprising, considering the low intensity of the campaign, especially in the media. Campaigns aimed at changing suicidal behaviors must be intensive.  相似文献
