论《刑事案件侦查》课程教学体系的改革

刑事案件侦查课程是公安院校侦查专业的一门主干课程。现行教学体系中存在与侦查观念的变化不相符、与法律法规不相适应、内容重复交叉、侦查方法归纳不完善、重点不突出等问题。改革刑事案件侦查课程的教学体系,应当以办案程序为主线,找出各类刑事案件侦查方法中的共性,将案件侦查的基本方法及侦查取证等内容融为一体,然后再针对不同案件的特点,分析侦查的难点与重点。     

构建和谐社会必须加强和谐建社区设

构建和谐社会是一个庞大的系统工程,祉区是社会的细胞,和谐社区是创建和谐社会的基石,只有每一个社区都和谐,才有可能实现整个社会的和谐.但目前社区建设中还存在一些不容忽视的问题,必须采取相应的对策,建立和完善祉区工作机制,从而发挥其在构建社会主义和谐社会中的重要作用.     

The effect of child support on welfare exits and re‐entries

Much of the literature on welfare dynamics has focused on the effects of recipient characteristics and state‐level characteristics such as welfare benefits and economic conditions; there has been very little analysis on the effects of child support. This paper, using the 1979‐1996 National Longitudinal Survey of Youth, examines whether child support affects the likelihood of leaving and re‐entering welfare. The results indicate that strong child support enforcement is important in helping young mothers exit and stay off welfare. Women with $1000 child support payments in the previous year were 18 percent more likely to exit welfare and 12 percent less likely to re‐enter welfare. Compared with women in states that pursued child support least vigorously, women in states that had passed extensive child support enforcement legislation and that spent more money on child support enforcement were 79 percent more likely to exit welfare and about 60 percent less likely to re‐enter welfare. © 2002 by the Association for Public Policy Analysis and Management.

住肉孢子虫病免疫学诊断方法的研究

本文以间接血凝试验(IHA)、酶联免疫吸附试验(ELISA)、荧光抗体试验(IFA)、斑点酶联免疫吸附试验(Dot-ELISA)等4种免疫方法诊断水牛、黄牛和猪的住肉孢子虫病,检出率分别为77.6％(其中水牛为93.4％,黄牛为65.9％),96.1％(其中猪为59.2％,小牛及青年牛为71.4％,成年牛为97.5％),97.5％和97.8％。其中应用IFA、Dot-ELISA诊断家畜住肉孢子虫病,在国内尚未见有报道。试验表明,免疫学诊断技术是当前对家畜住肉孢子虫病进行生前诊断的主要方法。

Study on the application of parent-of-origin specific DNA methylation markers to forensic genetics

In paternity test, especially in motherless cases, the allele inherited from father (obligatory gene, OG) often cannot be determined. The paternity exclusion probability (PE) of a genetic marker is reduced considerably. Therefore, it is necessary to develop a new technique, by which the parental origin of alleles can be determined without genealogical analysis. In this paper, we explored the possibility of using parent-of-origin specific DNA methylation markers to determine the parental origin of alleles, choosing the imprinted single nucleotide polymorphism (SNP) locus rs220028 (A/G) as a model system. We typed the SNP by mutagenically separated PCR (MS-PCR). The frequencies of alleles were A = 0.5085, G = 0.4915; the unbiased heterozygosity was 0.5020. In order to discriminate between the maternal allele and paternal allele, post-digestion MS-PCR, a novel PCR based methylation analysis and SNP typing technique was developed and performed on 18 heterozygous children, and the methylated maternal allele was detected specifically. As a pilot study on the use of epigenetic markers in forensic genetics, our results demonstrated the feasibility of using parent-of-origin specific DNA methylation markers to determine the parental origin of alleles.
