The method involves a single extraction of the drug and the internal standard, etidocaine, from alkalinized plasma with n-hexane. The gas chromatograph is equipped with a glass column (2.0 m x 2 mm) packed with 3% W/W SP2250 on Chromosorb W, (80/100 mesh) and a nitrogen sensitive detector. The method can accurately measure plasma bupivacaine concentrations down to 0.01 micrograms ml-1 using a sample size of 0.5 ml. The day-to-day variation of bupivacaine at 2.0 micrograms ml-1 is 6.90% (n = 10). The calibration graph is linear over the range 0.1-4.0 micrograms ml-1. The method is accurate, fast and sensitive and has been applied in a pharmacokinetic study of bupivacaine. 相似文献

ABSTRACT This article explains why Vietnam and China, one-party states that allow only one official trade union, are traversing different paths in their trade unions’ institutional structures, the state’s and trade union’s attitudes towards strikes, their willingness to allow independent trade unions and willingness to engage with the international labour union movement. These will be examined in terms of the path dependency of their recent histories, in which changes have been incremental on a path laid down by pre-existing entrenched institutions, until each national system no longer operated properly and new contingencies obliged the leadership to revamp the system. As a consequence of China’s and Vietnam’s divergent path dependencies, when external contingencies finally forced institutional change, countries have veered onto divergent trajectories – the Trans-Pacific Partnership energising Vietnam to debate the acceptance of autonomous trade unions, while Xi Jinping in China has intensified Party control over industrial relations. 相似文献

Dimensionality of Hardiness and Its Role in the Stress-Distress Relationship Among Chinese Adolescents in Hong Kong 总被引:1,自引:0,他引:1
The three components of hardiness, life events, coping strategies, and psychological distress, were assessed in a sample of 245 Chinese secondary school students in Hong Kong. While commitment, control, and challenge were not clearly differentiable as distinct constructs, three dimensions interpretable as resigned acceptance, cynical concession, and pragmatic orientation emerged. In the stress-distress relationship, hardiness did not interact with stress to moderate its influence on distress, however, both hardiness and stress had independent main effects on distress. Although high hardy students, compared with low hardy students, did not appraise positive events as having greater impact, they perceived that negative events had significantly lesser impact. In addition, low hardy students reported using passive and avoidant coping strategies significantly more frequently than high hardy students. 相似文献

Judicial instructions (traditional American Law Institute vs. Guilty But Mentally Ill [GBMI]) were manipulated within an insanity defense vignette portraying a highly psychotic defendant. Construals were highly predictive of verdicts in both instructional conditions. Instead of influencing case construals, the GBMI option seems to operate by increasing respondents' decisional thresholds for insanity and guilty verdicts, creating a collapsing effect such that few such verdicts are rendered. Between-instruction comparisons reveal that the construals of respondents who choose insane and guilty verdicts are considerably more homogeneous and extreme under the GBMI conditions. Results suggest that many respondents intend their GMBI verdicts to signify diminished blame and punishment, indicating that such verdicts entail cognitive compromises that reflect both the thresholdraising effects and also probable confusion about the jurisprudential meaning of a GBMI verdict.This article is an expanded version of a paper entitled Insanity case construals are not simply verdict justification effects, which was presented at the 99th annual convention of the American Psychological Association at San Francisco, August, 1991. We would like to thank Linda Roberts, Norman Finkel, and the anonymous reviewers for their comments on an earlier version of this paper. Support for this research was provided in part by a grant from the Baldy Center on Law and Social Policy at the State University of New York at Buffalo. 相似文献

Low self-control is theorized to be a key correlate of delinquency. Using a nonadjudicated sample (N = 1057) from Hong Kong and Macau, the influence of self-control on self-reported violent and nonviolent delinquencies was investigated using Grasmick’s self-control scale. The influences of demographics and self-control on delinquency were also examined. Findings indicate that these adolescents are more likely to engage in overall delinquency, particularly violence, if they are older and if they are less educated. Age is the only demographic predictor of nonviolent delinquency. Risk-seeking behaviors and self-centeredness have significant influences on both violent and nonviolent delinquencies, while low frustration tolerance and preference for cognitive activities are only associated with an increased level of violent misconduct. These findings highlight the overall significant influence of self-control on adolescent delinquency in Chinese adolescents. Suggestions are offered to enhance adolescents’ self-control as a way to reduce their tendency to involvement in delinquent activities. 相似文献
