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

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.     

Lineup Identification by Children: Effects of Clothing Bias

This study examined effects of clothing cues on children's identification accuracy from lineups. Four- to 14-year-olds (n = 228) saw 12 video clips of individuals, each wearing a distinctly colored shirt. After watching each clip children were presented with a target-present or target-absent photo lineup. Three clothing conditions were included. In 2 conditions all lineup members wore the same colored shirt; in the third, biased condition, the shirt color of only one individual matched that seen in the preceding clip (the target in target-present trials and the replacement in target-absent trials). Correct identifications of the target in target-present trials were most frequent in the biased condition, whereas in target-absent trials the biased condition led to more false identifications of the target replacement. Older children were more accurate than younger children, both in choosing the target from target-present lineups and rejecting target-absent lineups. These findings suggest that a simple clothing cue such as shirt color can have a significant impact on children's lineup identification accuracy.     

新闻从业者的媒介角色认知--兼论舆论监督的记者主体作用

调查表明,在上海这个国内经济活动最为活跃、舆论监督却乏善可陈的城市,"以天下为己任"的道德传统,依然是今天的新闻从业者个人价值体系中的重要底色。对于大多数新闻从业者来说,选择从事新闻工作,更多地是出于对大众传播媒介所能够担负起重要的社会道义责任的向往,同时也出于自身的兴趣爱好。至于对名利的追逐,显然并不是选择新闻业的首要因素。这一点,正是记者作为正在走向专业化的个体,在新闻媒介实行舆论监督当中发挥作用的重要思想基础。

一种基于Otsu算法的印章二值化算法

本文提出了一种基于Otsu算法的印章二值化法.该算法通过对算法的改进,考虑了印章图象象素的灰度分布值和它们邻域象素的平均灰度值分布情况.并不是用于整幅印章图象,而是用于分块的印章图象.实验证明,该算法适合印章的二值化处理.     

Regulation in Comparative Perspective

Structural changes in the world economy pose challenging new problems for comparative policy analysis. One such problem is the harmonization of domestic policies and institutions, which the Uruguay Round of GATT negotiations has identified as a key principle of international economic relations. Harmonization may mean the creation of a single policy space out of a number of distinct jurisdictions. It can also mean the adoption of common policy goals or general principles that national governments can pursue by different strategies. Comparative analysis can help in choosing the type of harmonization most appropriate in a given context. This article analyzes the development of harmonization strategies in the European Community/European Union. The European experience shows that far-reaching economic integration can be achieved without suppressing cultural diversity and legitimate differences in national preferences.
