EXCEL多元回归分析在痕迹数据处理上的应用

在痕迹检验技术中,很多推算公式是由回归分析预测法得出的。多元回归分析预测法的计算,虽然可以用常用计算器进行统计,但是数据复杂繁琐,工作量较大。Excel是一种办公系统软件,运用它的强大数据分析功能,只输入一次原始数据,而后全部以鼠标操作即可自动生成回归方程。文章以一组足迹数据分析为例,首先介绍相关分析,然后建立回归模型,最后计算出相关的回归方程。     

试析我国统一司法考试制度

2002年我国将实行统一司法考试制度。国家统一司法考试制度是指国家通过立法的方式确立的司法考试资格、司法考试科目和内容、司法考试方式和组织机构及管理的一项国家司法制度。为了实现考试面前人人平等,建立一项完备的统一司法考试制度是十分必要的。     

民事诉讼司法认知对象范围探讨

司法认知是世界上许多国家证据法上所普遍适用的就某些特定的案件事实由法官直接加以确认 ,从而免除当事人举证责任的一种诉讼规则。我国关于司法认知的立法与研究同外国相比差距较大 ,在民事诉讼中如何客观地界定司法认知的对象范围 ,尚需深入研究。笔者认为 ,民事诉讼司法认知对象有事实和法律两方面。事实范围包括众所周知的事实、司法事实、政府事实、易于获知的事实 ;法律范围包括本国法、国际条约和惯例、外国法。

物理场论对哲学思考的提示

哲学思考从物理学的"场”和"场论”得到如下提示将"相互作用及其连续性”的观点引入哲学领域,并进行全面的拓展与全面的深化;以"非实体主义”的基本理论为参照系,为众多的哲学问题求索新的答案;以"非决定论”的基本理论为参照系,引导相关的哲学问题寻找新的回应;"非决定论”与"非实体主义”结伴而行;"场”和"系统”这对范畴、"相互作用”的两套理论模式,可分可合、相互补充;与"物理场”相似,"哲学场”中相互作用的多方相对相关、互渗互补;摹拟理论物理学的"大统一场论”,建构包含古今中外多种哲学体系之间和流派之间相互作用的"哲学理论场的场论”.     

A screening method for urinary methamphetamine--latex agglutination inhibition reaction test

Methamphetamine in urine samples from abusers was detected by the latex agglutination inhibition reaction test with latex-antibody (Latex-Ab) and latex-methamphetamine (Latex-MA) reagents. Anti-methamphetamine antibody was produced in rabbits by immunization with bovine serum albumin (BSA)-methamphetamine conjugate. Latex particles were coated with antibodies or with rabbit serum albumin (RSA)-methamphetamine conjugate to obtain Latex-Ab and Latex-MA reagents, respectively. The results are read at 4-5 min after mixing the latex reagents. The sensitivity of this method for methamphetamine was 0.4 micrograms/ml urine. Methamphetamine analogs (methylephedrine, amphetamine, phentermine, methoxyphenamine, ephedrine, beta-phenylethylamine, OH-methamphetamine, OH-amphetamine, and OH-ephedrine) all cross-react in varying degrees, while glucosiurea and albuminurea give false positive results in the tests. Though attention must be paid to these effects this simple and rapid test is suitable for the mass screening of urine samples.     

Education cooperation in the European Union at the threshold of the New Millenium

The principles of ‘double relevance’ and ‘user-friendliness’ are seen as being essential for the implementation of the EU education programmes SOCRATES II and LEONARDO da VINCI II. Against the background of the acquis in EU education cooperation two points are explored: a) the articles of the Treaty are not fully used, and b) the framework set is increasingly proving to be too restrictive. The Luxemburg process and the Bologna conference are the reason for the second point. The opinion is put forward that the exchanges of students and teachers and the information exchange can be further europeanized and, eventually, be organized in permanent European structures. This revised version was published online in July 2006 with corrections to the Cover Date.

甲基苯丙胺稀土荧光试纸条的研制

目的建立一种检测尿液中甲基苯丙胺物质的高灵敏度检测方法。方法以稀土荧光纳米颗粒为标记物,采用反应杯+试纸条的反应模式,建立了免疫层析法,用于尿液中甲基苯丙胺的定性检测。结果用所制备的试纸条检测尿液中的甲基苯丙胺,肉眼和仪器判读的敏性均为100ppb,与吗啡、亚甲二氧基苯丙胺、氯胺酮、苯丙酮、可卡因等无交叉反应;将制备的反应杯和试纸条置于37℃7d,试纸条的性能没有明显降低。结论本研究建立的甲基苯丙胺免疫层析法用于定性检测尿液中的甲基苯丙胺,具有较高的灵敏性和较高的应用价值。     

Inferring ancestral origin using a single multiplex assay of ancestry-informative marker SNPs

Tests that infer the ancestral origin of a DNA sample have considerable potential in the development of forensic tools that can help to guide crime investigation. We have developed a single-tube 34-plex SNP assay for the assignment of ancestral origin by choosing ancestry-informative markers (AIMs) exhibiting highly contrasting allele frequency distributions between the three major population-groups. To predict ancestral origin from the profiles obtained, a classification algorithm was developed based on maximum likelihood. Sampling of two populations each from African, European and East Asian groups provided training sets for the algorithm and this was tested using the CEPH Human Genome Diversity Panel. We detected negligible theoretical and practical error for assignments to one of the three groups analyzed with consistently high classification probabilities, even when using reduced subsets of SNPs. This study shows that by choosing SNPs exhibiting marked allele frequency differences between population-groups a practical forensic test for assigning the most likely ancestry can be achieved from a single multiplexed assay.
