家兔死后眼玻璃体液消光度与死亡时间关系研究

目的 为寻找一种精确推定死亡时间的方法。方法 应用 754分光光度计,在 420nm波长下,检测了 48只家兔死后不同时间的眼玻璃体液消光度,探讨其与死亡时间的关系。结果 眼玻璃体液消光度（ X）与死亡时间（ Y）呈线性正相关（ r=0.983 27, P< 0.05）,在死后 0～ 72小时,眼玻璃体液消光度与死亡时间存在回归关系（ F=116.54, P< 0.05）,直线回归方程为： Y = 453.30X＋ 0.75 [Y为死亡时间 (PMI),单位为小时; X为眼玻璃体液消光度 ]。结论眼玻璃体液消光度的测定可作为推断死后 72小时内死亡时间的参考指标之一。     

大鼠 Fn剪接异型体分布及皮肤损伤后表达研究

目的研究成年大鼠、新生幼鼠纤维连接蛋白剪接异型体 EⅢ A、 EⅢ B体内分布及皮肤切创、挫伤后表达情况 , 以期为法医学损伤经历时间研究探索新指标及选择阳性对照 . 方法组织匀浆后抽提总 RNA, 逆转录聚合酶链反应 ( RT- PCR) 技术扩增目标条带 . 结果 (1)正常皮肤 EⅢ A+ 、 EⅢ B+ 不表达 , 伤后 18h EⅢ A+ 位点高丰度表达 , EⅢ B+ 位点变化不明显 , 两种致伤方式表达结果差别不大 ; (2)成年大鼠各器官分布情况依次为脑、心、肝 . 结论 EⅢ A+ 可作为皮肤损伤研究的敏感指标 .     

大鼠肾细胞核 DNA含量与死亡时间关系的研究

目的 研究 DNA含量与死亡时间关系。方法 应用计算机图像分析技术,测定了 15只大鼠在死后 48h内不同时间点大鼠肾细胞核 DNA含量的面积（ Area）、等效直径（ Mean－ Dia, MD）、异形指数（ Index of density, ID）、平均光度（ Average optical density, AOD）、积分光度（ Integral optical density, IOD）、密度变化数（ L－ Den－ Coe, LDC）和平均灰度（ Average gray, AG）等七项参数的变化值。结果 在大鼠死亡的相对早期（ 48h内）,其细胞核 DNA降解速率与 PMI具有一定相关性。本实验并将每个参数的测量值进行了多项式运算,获得了更能体现 DNA降解趋势的二项式回归方程。结论 应用计算机图像分析技术,测量机体死后 DNA含量变化,将会成为推断死亡时间精确、客观的新方法。     

调解、诉讼与公正——对现代自由社会和儒家传统的反思

调解作为一种解决纷争的做法和制度 ,是我国传统法律文化尤其是儒家法律文化的重要部分。在现代法治社会中 ,调解否已经过时 ?本文首先介绍中国的调解传统的哲学基础、理论和实践 ,然后从现代自由主义和法治理想的角度 ,对传统的调解提出批判。本文进而指出 ,调解在当代的中国以至西方仍有顽强的生命力 ,西方学者对调解作为“解决纠纷的另类选择”之一提出了多种理论依据 ,其中不少与儒家传统的睿见不谋而合。本文的结论是 ,经过“创造性转化”后的调解理论与实践能对现代文明作出贡献 ,由此可见 ,传统文化遗产在现代仍是十分宝贵和有用的资源。     

甲基苯丙胺在豚鼠毛发中分布及转化的初步研究

目的对甲基苯丙胺在豚鼠毛发中分布及转化机制进行初步研究。方法利用GC/MS,GC/NPD法,测定单次及多次给药豚鼠毛发中MAP、AP的含量变化过程,考察给药剂量与毛发中MAP、AP的含量间的关系,并研究毛发颜色对染毒豚鼠毛发中MAP、AP含量的影响。结果单次及多次给药豚鼠毛发中代谢产物AP均高于原体MAP,给药时间及给药剂量与毛发中MAP、AP的含量显著相关,同体豚鼠黑色毛发中的MAP、AP含量均明显高于棕色、白色毛发。结论给药方式、给药剂量及毛发颜色对豚鼠毛发中MAP、AP的含量均有显著影响。     

Examining Ethnic Identity and Self-Esteem Among Biracial and Monoracial Adolescents

The psychological well-being and ethnic identity of biracial adolescents are largely underrepresented topics in current scholarly literature, despite the growing population of biracial and multiracial individuals in the United States. This study examined self-esteem, ethnic identity, and the relationship between these constructs among biracial and monoracial adolescents (n = 3282). Using analysis of covariance, significant differences emerged between biracial and monoracial adolescents on both a measure of self-esteem and a measure of ethnic identity. Specifically, biracial adolescents showed significantly higher levels of self-esteem than their Asian counterparts, but significantly lower self-esteem than Black adolescents. Furthermore, biracial adolescents scored significantly higher than Whites on a measure of ethnic identity, but scored lower than their Black, Asian, and Latino peers on the same measure. Finally, correlational analyses revealed a significant and positive relationship between ethnic identity and self-esteem for all groups.     

Quentin Skinner on the Proper Meaning of Republican Liberty

This article examines Quentin Skinner's revisionist project of reconciling republican liberty and negative freedom. His conceptualisation is analysed in the contexts of both contemporary political theory as well as a historiographical interpretation of Machiavelli. Skinner advances two claims: first, that Machiavelli's idea of liberty is negative freedom, and second, that republicanism shows that liberty is best maintained by the coercive use of the law. I argue that there are two conflicting concepts of the law underlying Skinner's theory. One regards the law as an invisible hand, while the other takes the law to be a liberating agency. Skinner's influence on the emerging juristic paradigm in republicanism is also considered.
