This article reports the outcome of gas chromatography/tandem mass spectrometry confirmations for THC and carboxy-THC on 93 hair samples screened by RIA for cannabinoids. The samples were taken from probationers in Pinellas County, FL, who voluntarily provided the research staff with six hair and six urine specimens, collected at 1-month intervals. There were 40 samples that were RIA (+), urinalysis (−). Samples were selected which had cannabinoid (+) outcomes for hair, urine, or both. The THC and/or the carboxy-THC was (+) on confirmation. Of these 40 samples, 22 were (+) for both THC and carboxy-THC, 15 were (+) for THC but not carboxy-THC, and three were carboxy THC (+), but THC (−). Only one sample had a (+) RIA, but was (−) for both THC and carboxy-THC on confirmation. RIA detection of cannabinoids was confirmed in nearly all cases. Most cases that were RIA (−) but urine (+) were cannabinoid (+) when analyzed by GC/MS/MS. 相似文献

Political leaders in many countries have experienced growing problems of capacity in the postwar period, a development leading to an increase in the delegation of authority to public administration and civil servants. This delegation of authority creates a significant potential for discretionary decision-making authority on the part of public bureaucrats. One way of studying how bureaucrats handle this situation is to focus upon bureaucratic roles. Bureaucratic roles traditionally contain both political and professional norms. This article discusses how these political and professional considerations can be defined and how these norms are balanced given the potential for conflict which is present. The discussion is illustrated by measuring the perception of bureaucratic norms and role enactment among civil servants in Norwegian ministries. Results indicate that civil servants appear to have few problems in attending to and balancing both political and professional role norms. 相似文献
