This article deals with the reliability of child witnesses, in particular from the viewpoint that child witnesses should be treated with suspicion because their memories are very susceptible to suggestion. An experiment is reported, in which grade 3, grade 6, and college students were compared on their ability to recall events from a film, in the face of (mis)leading questions from an interrogator. The data showed that the grade 6 students were equal to the college students in memory capacity and in their ability to resist suggestion. The grade 3 students were inferior to the older subjects in these areas. However, the results from a second testing session led to the conclusion that although the younger children appeared to submit to suggestion much more readily than the older subjects, the effect of suggestion on actual memory was not significantly different for the three subject-groups. The implications of these findings are discussed with reference to the present status of child witnesses in Anglo-Saxon law systems. 相似文献

Using qualitative methods, this study examined how, and under what circumstances, suicidal men used mental health services. In particular, the analyses focused on fragmented pathways to care. Fifteen men with a history of suicidal and aggressive behaviors and a diagnosis of borderline personality disorder and/or antisocial personality disorder participated in semistructured interviews that consisted of questions about their mental health status and experiences with mental health and addiction services. Interviews were taped and transcribed. An iterative, inductive qualitative analytic process was used. Men followed a cyclical pattern wherein negative experiences with health care providers were said to be followed by avoidance of health care settings, crisis, and then by involuntary service utilization. Men identified five health care provider and three personal practices, and two types of episodes they believed to contribute to their fragmented pathways to care. Implementation of specialized interventions, and providing patients with more information and more opportunity to participate in decisions, may improve interactions between patients and providers and improve patients' mental health status. 相似文献

Issues in both the children of alcoholics and child abuse literatures were addressed in an attempt to disentangle the effects on young adults of growing up in alcoholic homes versus abusive homes. Using multiple regression, retrospective reports of parental abuse (emotional, physical, and sexual) and parental support (love/support, independence, and fairness), witnessing violence between parents, and parental alcohol use were used as predictor variables for outcomes noted by both literatures. When the effects of all other predictors were statistically controlled, parental alcohol use was not significantly related to depressive symptoms or aggression. Different abusive and supportive behaviors, depending on sex of parent and sex of participant, were significant predictors of both depression and aggression. Results underscore the importance of including and controlling for inter-parental violence and for different types of child abuse (especially emotional abuse) and parental supportive behaviors in investigations of outcomes related to abusive and alcoholic families. Implications for treatment of individuals from these families are discussed. 相似文献

Our headspace gas chromatographic flame ionization detection (HS-GC-FID) method for ethanol determination showed slightly, but consistently, low ethanol concentrations in whole blood (blood) in proficiency testing programs (QC-samples). Ethanol and acetaldehyde were determined using HS-GC-FID with capillary columns, headspace equilibration temperature (HS-T degrees ) of 70 degrees C and 20 min equilibration time (HS-EqT). Full factorial designs were used to study the variables HS-T degrees (50 degrees -70 degrees C), HS-EqT (15-25 min), ethanol concentration (0.20-1.20 g/kg) and storage at room temperature (0-6 days) with three sample-sets; plasma, hemolyzed blood and non-hemolyzed blood. A decrease in the ethanol concentration in blood was seen as a nearly equivalent increase in the acetaldehyde concentration. This effect was not observed in plasma, indicating chemical oxidation of ethanol to acetaldehyde in the presence of red blood cells. The variables showed different magnitude of effects in hemolyzed and non-hemolyzed blood. A decrease in ethanol concentration was seen even after a few days of storage and also when changing the HS-T degrees from 50 to 70 degrees C. The formation of acetaldehyde was dependent on all the variables and combinations of these (interactions) and HS-T degrees was involved in all the significant interaction effects. Favorable instrumental conditions were found to be HS-T degrees of 50 degrees C and HS-EqT of 15-25 min. The ethanol concentrations obtained for the range 0.04-2.5 g/kg after analyzing authentic forensic blood samples with a HS-T degrees of 50 degrees C were statistically significantly higher than at 70 degrees C (+0.0154 g/kg, p < 0.0001, n = 180). In conclusion, chemical oxidation of ethanol to acetaldehyde in the presence of red blood cells has been shown to contribute to lowered ethanol concentrations in blood samples. Storage conditions before analysis and the headspace equilibration temperature during analysis were important for the determination of blood ethanol concentrations. 相似文献
