溺死法医学鉴定的研究新进展

综述了近年来在硅藻检验、水中浮游生物叶绿素（A）检测、血液化学和组织化学检验等方面的最新文献报道,并对各种溺死检验方法的优缺点进行了评价：在硅藻检验中,硝酸乙醇法、破机罐法及微波消解法,可缩短检验时间,提高办案效率;酶消化法及PCR法硅藻检出率高,适用于可疑水样中硅藻密度低等情况。早期器官组织中浮游生物叶绿素（A）、血液和组织中其他生化指标,可作为鉴定溺死的重要参考。微量元素锶检测可用于鉴定海水中溺死。另外,硅藻及其他浮游生物遗传多态性片断PCR,可望成为新的、灵敏的溺死检测方法。     

Identification and dating of the fountain pen ink entries on documents by ion-pairing high-performance liquid chromatography

A novel approach for the identification and dating of the fountain pen ink entries on paper has been established by ion-pairing high-performance liquid chromatography (IP-HPLC). Twelve black and six red fountain inks have been collected, and their ink entries have been prepared by drawing lines on paper. The chromatographic conditions for separation of their dye components after extraction with solvents were optimized. Under the optimized conditions, the 18 fountain pen inks were differentiated individually by comparing the number of detectable main or minor dye components, and the relative peak intensities of each component. The ink entries were artificially and naturally aged, and the analysis results showed that the ink dye components were significantly decomposed when exposed to UV or fluorescent light compare to those of inks stored under natural condition. The changes of the relative peak height for the dye components were linearly related to the aging time, especially under natural aging conditions. The degradation characteristics of the dye components under different aging conditions provide scientific evidences for dating of the suspicious fountain pen ink entries on document.     

论单位犯罪的界定标准

单位是与自然人并列的一类社会主体,是人格化的社会系统。单位成员在单位犯罪中具有二重性特征,而单位具有独立的社会系统的实质特征和法律确认的合法性的形式特征。单位成员行为成为单位犯罪行为须同时具备以单位名义和因单位利益两个条件。     

“入世”与我国地理标志保护

根据世贸组织的有关规则 ,我国一旦加入世贸组织 ,将无条件地承担起对其它世贸组织成员地理标志的保护义务 ,同时 ,对方也必须对我国的地理标志实行保护。然而 ,我国国民特别是工商界人士目前对“地理标志”这一概念仍比较模糊 ,保护意识淡薄。政府有关部门对地理标志的管理和保护状况也令人担忧。本文针对我国地理标志管理和保护工作的现状与存在问题 ,提出了一些相应的改进措施和建议     

Adolescent Siblings’ Looking Glass Self-Orientations: Patterns of Liabilities and Associations with Parenting

A looking glass self-orientation refers to the tendency to incorporate the opinions of social partners to form a self-representation and approve of one’s self. These orientations were assessed for two adolescent siblings in 438 families with surveys accessed on-line. Younger (M = 11.6 years, SD = 1.8) and older (M = 14.3, SD = 2.1) siblings and their mothers (82.7% European-American) participated. The siblings shared similar orientations in relying on either classmates or the other sibling for approval, prior to self approval. Relying on classmate approval was significantly associated with adjustment and academic performance as reported by both the self and mothers. Siblings were also identified as sources of approval with implications for adjustment, but the magnitude of the associations with adjustment were lower. Comparisons of the older and younger siblings revealed that both groups were equally as liable to poor outcomes when reflecting the opinions of classmates or siblings. The results of SEM analyses implicate parenting characterized as coercive, rejecting, and chaotic in association with the tendency to rely on others for approval. A mediating role for looking glass self-orientations in associations between parenting and depressive symptoms, anxiety or academic performance was also found.

开放式基金业绩实证研究

分析评价开放式基金业绩,是一个现实而有意义的课题.其中的实证设计直接涉及如下主要因素:样本基金的选择、基准组合的选取、无风险利率和基金周收益率的计算、数据来源及应用软件的确定等.在此基础上,通过运用收益率评价法和风险调整收益法,对所选16只样本基金2005年和2006年的业绩进行对比研究后发现:样本基金的业绩与证券市场行情密切相关,受到股票市场环境的主导性影响;这种主导性影响主要体现在对开放式基金投资收益和风险的影响上.因此,研究我国开放式基金业绩应密切联系其所处的证券市场环境.

试论邓小平价值观的两个方面

价值观思想是邓小平理论的一个重要组成部分。邓小平价值观思想对马克思主义价值观的新贡献就在于把价值观进行了两个方面的区分 ,即人生价值观和方法论价值观。把价值观与方法论相结合 ,是邓小平价值观思想的一大特色 ,是对马克思主义价值观理论的新发展。
