The present study uses data on the processing of felony defendants in large urban courts to examine Hispanic, black, and white differences at the pretrial release stage. The major finding is that Hispanic defendants are more likely to be detained than white and black defendants. And, racial/ethnic differences are most pronounced in drug cases. In fact, Hispanic defendants suffer a triple burden at the pretrial release stage as they are the group most likely to be required to pay bail to gain release, the group that receives the highest bail amounts, and the group least able to pay bail. These findings are consistent with a focal concerns perspective of criminal case processing that suggests Hispanics as a newly immigrated group are especially prone to harsher treatment in the criminal case process.  相似文献

The structural economic reforms justified by neoliberal ideas that transformed Mexico's statist political economy in the 1980s posed a direct challenge to the nationalism inherited from the revolutionary era that had long served to legitimise the interventions of the social state. This article examines the strategy adopted by the administration of President Carlos Salinas de Gortari (1988–1994) to reconcile the rival ambitions of neoliberalism and nationalism and its reasons for doing so. It does so by examining ideas concerning the state, society and the individual found in writing and speeches published in political organs and the press during this period.  相似文献

In the course of history, the meaning of fa (a Chinese character with an approximate meaning of “law”) has not been invariable, and its connotation in modern times has been enriched constantly, so as to incorporate many elements of ancient li (ceremony). If the modern concept of law, already changed and still changing, is to be used to mechanically compare and interpret traditional Chinese law, misunderstandings might arise. Actually, li and fa are indispensable components of traditional Chinese law, and the lack of necessary study of the li will prevent us from understanding and explaining the spirit of traditional Chinese law. In traditional Chinese law, “fa” usually refers to an institutional dimension, especially after Qin and Han dynasties, whereas li, especially li yi (moral basis for rites and ceremonies), is where the value and spirit of traditional Chinese law can be found.

汉族人群五个STR基因座的多态性调查   总被引:22,自引:9,他引:13  
应用PCR及PAG电泳技术研究了PLA2A、vWA、CYP19、TH和LPL五个基因座的多态性,调查武汉地区汉族无关个体,获得汉族人群的频率分布。五个基因座基因型频率分布与Hardy-Weinberg平衡吻合良好、分别计算基因座的杂合度(H)、个人识别能力(Dp)、非父排除率(PE)和多态性信息总量(PIC)。为法医学应用提供了基础数据。  相似文献

房居事关民生,中央政府已出台一系列政策,仍无法控制房价的飞涨.需求和供给能解释大部分高房价,但仍无法解释为什么中央政策的失效.高房价是一系列主体的行为所导致,政府之间、政府部门间的冲突放纵了房价的上涨.更深刻的原因在于我国政制的不足,权力行使应被制约,但也要使它有效协调运作.  相似文献

目的探讨冠状动脉内弹力膜(IEL)病变与冠心病猝死(SCD)的关系。方法从本单位近5年尸检案例中挑选60例病例和心脏标本,分为SCD组、对照组A和B组。每例分别在冠状动脉左前降支近段取材,常规制片,HE和双重组合特殊染色,显微镜下观察冠状动脉IEL,并用图像分析技术对特殊染色的IEL进行形态定量分析。结果60例中,SCD组(男性24例,女性6例,年龄30~83岁)的冠状动脉IEL缺失明显(缺失率=41.64%),未缺失的IEL失去原有弯曲度而变平直;对照组A(冠心病非猝死者,男性13例、女性2例,年龄41~80岁)的冠状动脉IEL缺失程度较SCD组稍轻(缺失率=30.53%);对照组B(无冠心病的其他死者,男性8例,女性7例,年龄17~54岁)的冠状动脉IEL仅有轻度缺失(缺失率=15.67%),多保持原有波浪状结构。统计学分析显示,SCD组与对照组、SCD组与对照组B、对照组A与对照组B之间IEL缺损率的差异均具有极显著性意义;SCD组与对照组A在IEL缺损率上的差异有显著性意义。结论SCD与其冠状动脉IEL缺损率的大小密切相关。  相似文献

A method has been developed on reverse phase high performance liquid chromatography for simultaneous determination of methyl, ethyl and isopropyl alcohols under refractive index detection using pure water as the mobile phase. A good separation has been achieved between these alcohols. Detector response was linear with a detection limit of 5 mg/100 ml. Recovery studies were performed by adding known amounts of methyl and ethyl alcohols to blood, lung and liver within the range 80–90%. The reproducibility of the results was always >90%. The quantitative distribution of methyl alcohol in postmortem body tissues and fluids has been reported in three cases of poisoning.  相似文献

用猪圆环病毒2型(PCV2)经腹腔注射BALB/c小鼠及裸鼠各15只,每隔2周1次,共感染3次。BALB/c小鼠初次、再次感染后均未出现明显的临床症状,仅有2只小鼠出现病理变化;从血清中可检测到PCV2核酸及其ORF2抗体;同时淋巴细胞增殖反应显著增强,NK和CTL细胞杀伤率显著升高;CD4+、CD8+、CD3+T淋巴细胞及CD19+B淋巴细胞数量显著减少。裸鼠也未出现明显的临床症状,从血清中可检测到PCV2核酸,但未检测到PCV2 ORF2抗体;除NK细胞杀伤率显著升高外,其余免疫学指标无显著改变。结果表明,BALB/c小鼠比裸鼠对PCV2易感,各项免疫学指标变化与PCV2感染猪一致,但不表现临床症状,仅个别BALB/c小鼠出现病理变化,说明BALB/c小鼠对PCV2不如猪易感。  相似文献

Using international data for 100 countries, we test two hypotheses derived from Bonger's Marxian theory of crime. The analyses support the hypothesis that the degree of capitalism significantly predicts homicide rates, but they fail to confirm that the de‐moralization of the population (loss of moral feelings for others) mediates the relationship between capitalism and homicide. Although capitalism is not the best predictor among those considered, overall, the results underline the importance of Bonger's ideas because both capitalism and corruption (our indicator of de‐moralization) show reasonably strong relationships with homicide rates and compete with other variables commonly used as predictors of international homicide rates. The results confirm the usefulness of attempting to subject Marxian ideas to positivist, quantitative tests, with an eye to integrating Marxian theories with other mainstream theories, such as institutional anomie theory.  相似文献

With the divorce rate rising and related child visitation disputes becoming an increasingly difficult issue before the courts, supervised visitation programs have proliferated over the last decade. The literature demonstrates that ongoing contact between children and both parents following separation and/or divorce is important for children's socio‐emotional adjustment and positive child/parent relations. However, there is a paucity of literature demonstrating a relationship between supervised visitation programs and child/parent relationship outcomes. Based on the lack of outcome research the authors argue for a second generation of research regarding intended and unintended consequences of supervised visitation. This article reviews and synthesizes the current literature, highlighting strengths, limitations, significant findings and proposes a critical need for evidence‐based research.  相似文献
