1963年2月下旬,毛主席题词“向雷锋同志学习”。3月5日,《人民日报》、《解放军报》、《中国青年报》等报刊发表以后,全国青年乃至全国军民热烈响应,迅速掀起了学雷锋活动的高潮。在毛主席题词之后,总政首长亲自向中共中央其他常委写报告,请求题词,在《解放军报》上刊登。刘少奇、周恩来、朱德、邓小平等同志陆续题了词。《解放军报》于3月6日首先刊载题词手迹后,进一步推动了全国学雷锋活动热潮。在中央常委题词过程中,周总理的一件事给我很大教育,至今印象很深。那段时间,我在解放军报社工作,正值上夜班。在周总理的…  相似文献

The present study explores the relationships between gender and imprisonment decisions in Minnesota before and after the introduction of sentencing guidelines. Results from a series of logistic regression models indicate that gender alone did not have a significant impact on the likelihood of imprisonment, but women with dependent children were significantly less likely to be imprisoned before sentencing guidelines and in the years subsequent to their implementation. The findings suggest that despite the introduction of sentencing reforms, court officials tend to return to issues of substantive justice, and they appear unable to shed their individual or organizational ideas of fairness in sentencing.  相似文献

Misidentification syndromes have been studied from a variety of perspectives, including phenomenological, biological, and nosological approaches. More recently, misidentification syndromes have been studied from a psychiatric-legal perspective, especially with regards to the problem of dangerousness. Capgras syndrome and other syndromes of misidentification can lead to hostile mood and subsequent physical violence. Little attention has so far been devoted to children as the objects of the psychotic person's misidentification delusion(s). We provide a review of cases from the anglophonic literature that have children as the misidentified objects, add three new cases, and then discuss the relationship between misidentification and potential harm to these children.  相似文献

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

Dutch criminality and its relation to the performance of police and justice have only recently been analyzed at the macro level (e.g., at the level of municipalities or the whole country). This type of approach is a useful supplement to analyses at the micro level (that of individuals), which are more common in Dutch empirical criminological research. The main results of such a macro approach are presented in this article. We conclude that the per capita numbers of youth, divorced people, and unemployed contribute significantly to the crime rate. The police strength and solving rates are important factors as well. Analysis of the production process of the police reveals that detecting one more case of driving under the influence is far more expensive than solving one more other crime or handling one more traffic accident. The results are combined to sketch a cost-benefit approach of different strategies in allocating more resources to the police. Allocating extra resources to solving more cases of vandalism gives the best cost-benefit ratio.  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
