A fatality following ingestion of the tricyclic antidepressant carpipramine (Prazinil) and ethyl alcohol is described. Carpipramine was quantitated by high performance liquid chromatography. The concentration of carpipramine was 2.0 mg/L in blood and 0.44 mg/L in urine. Ethyl alcohol was measured by headspace gas chromatography and found to be 105 mg/dL in blood and 55 mg/dL in the urine. Quantitative analysis of stomach contents was positive for carpipramine by thin-layer chromatography. To our knowledge, this is the first reported fatality involving carpipramine. 相似文献

This paper examines the psychological dynamics of the Group-Value Model for a behavioral orientation which has seldom been considered in the social justice literature: acceptance and support for change. A field study was conducted, with 176 participants members of an organization which was undergoing a change process. Participants were asked (a) to think of a specific relevant conflict situation with their supervisor; (b) to evaluate supervisor's behavior in that situation, with respect to relational and distributive justice; (c) to state the justice aspects most valued in conflict situations with their supervisor. A test of the model was conducted through a mediation analysis. According to the Group-Value Model (GVM), respect experienced within the group and pride in the group were mediating variables between justice judgements and orientation toward acceptance and support for change in the organization. Interactional and procedural aspects (relational judgements) were the only ones to predict pride, respect, and behavioral orientation, and were also the ones most valued in general conflict situations with the supervisor. The model was also tested at three different levels of analysis: organization as a whole, department, and work group. This confirmed pride and respect within the group as mediating variables between relational justice judgements and orientation toward acceptance and support for change at the department and workgroup levels. 相似文献

In the last thirty years, research on differential sentencing practices became one of the dominant thrusts of academic interest in criminal justice studies. This was mainly because several reforms had been added to the various sentencing structures in the United States, one of which was the adoption of guideline based sentencing strategies. Although several studies were conducted regarding the impact of these guidelines, these were provided by a limited number of sources. For instance, the majority of this research was conducted on data collected by the United States Sentencing Commission and the Pennsylvania Sentencing Commission. This study attempted to further the discussion on sentencing practices by examining data from a new source, the Arkansas Office of Courts. This study first examined the judge's decision to imprison and jail the defendant using logistic regression, and second, for those individuals incarcerated, OLS and negative binomial regression analyses were conducted to explore potential disparities in the length of prison and jail sentences. The results of this analysis in Arkansas illustrated striking comparisons to studies that were conducted on other guideline structures. The legally relevant variables were the greatest predictors of whether or not an offender was sentenced to prison. Extralegal variables, on the other hand, had negligible effects. Implications for policy are also discussed. 相似文献
