A gas chromatographic (GC) fingerprint method, based on the presence or absence of six congeners, was developed for illicit cocaine samples. The fingerprint utilizes the relative abundances of these congeners towards each other, disregarding cocaine as the main constituent, and can be expressed numerically or graphically in the form of pictograms for rapid visual comparison. The method can be applied directly to a solution of the sample in chloroform, without previous workup procedures. More than 70 unrelated samples were analyzed and a great variation was observed in the parameter composition. On the other hand, a remarkable similarity could be seen between related samples. The GC fingerprint method may be considered an important contribution for sample comparison, as is exemplified by a subdivision of the analyzed samples in different categories, based on the number and types of congeners found. 相似文献

We report a case of rapid death from thrombotic thrombocytopaenic purpura (TTP) in a young pregnant lady who developed full blown symptoms soon after caesarean section. Extensive intramyocardial confluent haemorrhages and widespread microthrombi in heart, brain, adrenals and kidney were found at autopsy. Thrombotic thrombocytopaenic purpura is an uncommon condition, which carries a high fatality rate if untreated. Awareness of this syndrome together with its high risk of sudden death underlines the importance of rapid diagnosis and treatment. 相似文献

A new solid-phase extraction procedure for the determination of cocaine and benzoylecgonine in amniotic fluid, using high flow co-polymeric sorbents is reported. The recoveries of cocaine and benzoylecgonine within the range 0.1-1 mg/l were 95.7% and 50.3%, respectively. The use of high-flow sorbents allowed the easy extraction of amniotic fluid regardless of sample viscosity or physical nature. The use of these solid-phase columns provided many advantages over the more commonly used solvent extraction, including an increase in extraction speed and efficiency, reduced operator time, reduced solvent use and disposal volumes and exceptional extract quality. Further, the determination of amniotic fluid obtained from pregnant cocaine users may provide important information about handling of cocaine by the fetus at various gestational ages. The procedure was successfully applied to amniotic fluid from suspected cocaine abusers. 相似文献

Conclusion This paper dealt with the relation between social skills and a) making a suspicious impression, b) the ability to deceive.
The results suggest that observers typically entertain perceptual distortion: introverted and socially anxious persons automatically
impress them as less credible while extroverts establish more credibility. Introverts and socially anxious people are more
likely to be designated as suspect in the sense of Article 27 of theCod of Penal Procedure-their extroverted and non-anxious counterparts run less risk on this point.
The results further show that social skills are related to the ability to hide the truth. The introverted and socially anxious
are poor liars.
In sum, we may conclude that the likelihood of criminal stigmatization is appreciably greater if one's behavior is introverted
or socially anxious because they impress others as suspicious (they run the risk of being apprehended more readily and they
will more quickly succumb under questioning). Eysenck's theory (1984) states that crimes are more strongly correlated with
extroversion. This means that extroverts have a double advantage. The double handicap for introverted and socially anxious
persons could be undone if detection officers would pay somewhat greater attention to the extroverted and socially non-anxious.
In addition, we would recommend that training programs for police officers include material on impression formation and impression
management as aspects of social skills. 相似文献

In many types of social situations, individuals defend their claims to a portion of the rewards by arguing that they are just. Although a great deal of research demonstrates that individuals differ in their distribution preferences and thus their beliefs about what is fair, the literature curiously omits consideration of the consequences of these differences, especially the conflict they may engender. This paper first reviews the few attempts to address such justice conflict. The limitations of these approaches suggest concerns to be addressed in an alternative framework. The paper presents a theoretical discussion of this alternative that integrates assumptions about distribution preferences, justice beliefs, conditions fostering the emergence of justice conflict, and elements of negotiation processes as a basic framework for predictions about the bargaining strategies individuals may employ to resolve competing justice claims. 相似文献
