This article examines the mode of understanding and experiences of family relationships of Chinese migrant women in Britain. In contrast to much existing research work on the patterns and experiences of postwar settlement of unskilled Chinese male labourers in Britain, the focus here is on the life stories of 41 Chinese women with different migration trajectories and varying economic and cultural capital. Their oral testimonies reveal Chinese women's diverse expectations and experiences of migrant family relationships and their different strategies to achieve self-fulfillment both within and outside the confines of the migrant family. For some women, migration brings opportunities for a fulfilling and independent lifestyle. They are successful in negotiating their way around and sometimes out of their initial familial and social position. For others, they bear the disproportionate cost and labour of familial strategies of advancement and remain vulnerable to the most constraining aspects of diasporic existence.  相似文献

检警一体化与检察指导侦查机制比较研究   总被引:3,自引:0,他引:3  
检警一体化是大陆法系国家一种比较成熟的刑事犯罪追诉模式 ,检察指导侦查则是我国理论界和司法实务界所积极探索与实践的一种刑事犯罪追诉创新机制。检警一体化机制与检察指导侦查机制的相同之处在于提高刑事司法效率、查清案件事相、预防侦查违法和防止诉讼偏差 ;不同之处在于产生的法律制度和理论背景不同、检察官的主导作用和对犯罪案件的决定权限不同、侦查主体的能动性发挥不同  相似文献

A method for simultaneous enantiomeric separation of ephedrine, pseudoephedrine, and methamphetamine (MA) in a single run by simple capillary zone electrophoresis (CZE) with beta-cyclodextrin as a chiral selector is described. The effects of the buffer pH, phosphate concentration, beta-cyclodextrin concentration, voltage and temperature on the peak resolution were examined. Good enantiomeric resolution was attained for each analyte under our optimized conditions: 15 mM beta-cyclodextrin, 300 mM NaH2PO4 at pH 2.5 with an uncoated capillary (64.5 cm x 50 microm), applied potential at 20 kV and temperature at 30 degrees C. Ultraviolet (UV) detection at a fixed wavelength (200 nm) was employed using a diode array detector. Using phentermine as an internal standard, migration times for all analytes are reproducible within 0.16% for intra-day and 0.6% for inter-day runs. Application of this method to the analysis of confiscated drugs is discussed.  相似文献

司法解释确立了举证时限(或证据失权)制度,从而使我国民事诉讼证据的随时提出主义转变为适时提出主义。但是证据失权制度是一把双刃剑,必须给证据失权以适当的救济,并设置相应的制度保障,即:在区分严格证明、疏明和加强法官对当事人举证指导的前提下,通过法官行使自由裁量权等方式进行,以期证据失权制度能够兼顾案件真实和诉讼效率,促进诉讼公正。  相似文献

Self-esteem and psychological symptoms were assessed in a sample of 1082 Chinese adolescents who responded to the Chinese versions of Coopersmith's Self-Esteem Inventory and the General Health Questionnaire. Three dimensions of self-esteem, interpreted as Family Acceptance/Rejection, Self-Depreciation, and Peer Affirmation/Disaffirmation, were found to relate substantially to general psychological symptoms and particularly to specific symptoms of anxiety, social dysfunction, and depression as reported by these adolescents. The implications of the relative importance of appraisal from internal feedback as sources of self-esteem as opposed to the external feedback from family and peers were discussed in relation to self-esteem enhancement in adolescents.Received his Ph.D. from the University of Western Ontario in 1978.

Like many other places in the world, Hong Kong has drink-driving legislation which prohibits a driver from having in his blood alcohol exceeding a prescribed limit while in control of a motor vehicle. The accuracy of measuring this alcohol concentration is obviously of prime concern as an erroneous result can avert the administration of justice. The common practice is to deduct all errors from the measured value and compare the deducted value with the prescribed limit, so that the benefit of all errors of the measurement is given to the driver. It is therefore important for any laboratory responsible for measuring blood alcohol concentrations to identify and quantify all errors associated with the measurement. The present study examined 900 blood alcohol determinations carried out by the Hong Kong Government Laboratory (HKGL) on cases of suspected drink driving. The determinations were performed by 5 different analysts with two different sets of instruments during 1995-1997. Statistical analysis indicated that the instruments had no bearing on the random error or variability and that even though analyst was a significant factor on variability, the deviation from the mean so caused was only 0.3% and of no practical significance. When the systematic error introduced by the tolerance limits of the certified alcohol standards (purchased from the Laboratory of Government Chemists, UK) was taken into account, the total uncertainty (random plus systematic errors) of an alcohol determination at 99.5% confidence level was found to be 4%. It is recommended that laboratories engaged in blood alcohol determination should adopt similar statistical treatment of their analytical results to find out the error and to ensure that the results are independent of analyst and instrument used.  相似文献

制作了13枚"同版"渗透型印章和激光雕刻印章,分析了这些"同版"印章的印面特征和盖印印文特征.研究发现,相同条件下制作的"同版"印章的个体差异十分微小,如果考虑到各种盖印条件下,这些印章盖印印文特征的变化范围,"同版"印章印文的检验是十分困难的,甚至是不可能的.  相似文献
