在视界交融中认识风险社会

风险社会理论逐渐受到学界的关注,但对风险社会的认识普遍存在着视界狭窄的问题。对风险社会的认识,应在生态危机、工业社会变迁、时空转换等视界的交融中加以描述和理解,以形成对风险社会广泛和深刻的认识。     

Fn-EIIIA金标试纸条进行损伤时间推断的效果评价

目的评价Fn-EIIIA金标单克隆抗体试纸条在人体皮肤组织损伤时间推断中的有效性和灵敏度。方法提取不同损伤时间人体皮肤组织,匀浆,用Fn-EIIIA金标单克隆抗体试纸条检测其Fn-EIIIA的表达,对其结果进行评价;同时,将大鼠挫伤皮肤组织置于自然环境中,分别提取不同自溶时间段的皮肤样本进行检测,对自溶变化对检测结果的影响进行观察。结果正常皮肤组织样本中试纸条检测线不显色,损伤1h后即显色,随损伤时间延长,试纸条检测线有显色逐渐加深的趋势;在观察时间段内,组织自溶对检测结果无显著影响。结论Fn-EIIIA金标单克隆抗体试纸条可作为法医学损伤时间推断敏感、稳定的检测手段。     

Development of a human-specific real-time PCR assay for the simultaneous quantitation of total genomic and male DNA

A duplex real-time quantitative PCR assay was developed for forensic DNA analysis, which provides simultaneous quantitation of total genomic human DNA and human male DNA. The assay utilizes two spectrally resolved fluorogenic probes in a 5' nuclease (TaqMantrade mark) assay. Within the range of organisms empirically tested and based upon theoretical specificity using National Center for Biotechnology Information GenBank sequences, primer and probe sequences were shown to be human specific, and the Y-chromosome probe, male-specific. A mixture-challenge study resulted in accurate quantitation of 25 pg male DNA in a mixture of up to 1:5000 (male:female DNA). Additional experimental results include comparisons with the slot blot method and commercial real-time PCR kits. The assay developed addresses the shortcomings of the traditional slot blot method as well as the commercial real-time PCR kits. This method is shown to be specific, relatively simple, rapid, has low limits of detection, and consumes limited sample in addition to reporting both the male and total genomic DNA concentrations present.     

论"耗散结构"和"相对论"中自然哲学观点的差异--纪念爱因斯坦逝世50周年

爱因斯坦(A.Einstein)(1879～1955)和普里高津(I.Prigogine)(1917-)分别是"相对论"(Theory of Relativity)和"耗散结构"(Dissipative Structure)的创始人,他们站在哲学的高度提出了相应的"世界模式".这些模式开拓了人们的眼界,创造了新的研究热点,改变了人们对自然界认识的传统习惯.     

大力弘扬与时俱进的创新精神

与时俱进是“三个代表”重要思想的关键和精髓 ,我们在工作中要深刻领会与时俱进的科学内涵和基本要求 ;准确把握创新的意义、内容和方法 ;大力弘扬与时俱进的创新精神 ;勇于开拓 ,求真务实 ,争当学习和实践“三个代表”重要思想的楷模。     

论转型期和谐社会建构与公民公共政策参与

“社会主义和谐社会”理念的提出意味着在目前转型时期的中国社会已经变得不和谐。利益变得多元化,不同社会主体的利益意识不断地被唤醒和强化,各种利益主体的自主权不断扩大,不同利益主体都极力想通过公共政策参与来维护和实现自己的利益,如何规范和引导该行为就成了构建和谐社会的关键。     

利用蜜罐技术改进P~2DR模型及在公安网络上的应用研究

当前公安网络安全体系还没有形成统一的网络安全策略,难以保障公安网络上公共信息的安全。P2DR模型将防护、检测、响应组成一个较完整的安全策略,是对传统安全模型的重大改进;蜜罐系统是基于主动防御理论的一种诱骗技术。利用蜜罐技术改进P2DR模型,提高了事前检测能力,并初步实现了在公安网络上的应用,提高了P2DR的效能,增加了公安网络的防御纵向深度。     

把握好贯彻"三个代表"重要思想的根本要求

贯彻"三个代表"重要思想的关键在坚持与时俱进,核心在坚持党的先进性,本质在坚持执政为民,这三者是"三个代表"自身三个不同层面上的内在要求,是互相联系、相互补充的整体。     

实验性大鼠脑震荡后C—FOS蛋白表达的研究

目的探讨原癌基因c-fos的表达和脑震荡性损伤的关系,同时寻找脑震荡后法医病理学的诊断依据。方法55只实验大鼠随机分为脑震荡组和对照组。用免疫组织化学SABC法观察大鼠脑震荡后脑内C-FOS蛋白表达的变化规律。结果对照组大鼠未见C-FOS蛋白的表达。然而脑震荡组损伤后15min即可在神经细胞观察到C-FOS蛋白的表达,随着损伤后经过时间的延长,表达C-FOS蛋白的细胞数及范围逐渐扩大,损伤后6h表达达高峰,直至损伤后96h均有大量C-FOS蛋白表达。结论 c-fos原癌基因的检测可成为诊断脑震荡和推断脑震荡后经过时间的一项敏感指标。     

Measuring Family Violence: The Conceptualization and Utilization of Prevalence and Incidence Rates

The present study argues for a standard conceptualization of prevalence and incidence in family violence research. Reviewing several definitions of both prevalence and incidence in the family violence literature, we identify important inconsistencies in conceptualizations. The use of time frame to distinguish incidence and prevalence seems to have been a main thrust of the conceptual confusion. A gold standard conceptualization is proposed that sees prevalence as the extent to which violent behavior is distributed in the population and incidence as the amount of violent behavior that occurs among those in the population who experience violence. A discussion of rates calculated with other conceptualizations illustrates the need for standardization as well as the utility of the conceptualization in the present study. The calculation of prevalence and incidence rates is exemplified with respect to interpartner violence using Statistics Canada's Violence Against Women Survey (VAWS). Using duration as an independent variable, we also illustrate how the choice of incidence or prevalence rates may affect the operation of risk markers. Given the need for standardization, the relative ease with which this can be accomplished, and the knowledge that research in this area will be conducted well into the future, we conclude with a plea for a standard use of prevalence and incidence among family violence scholars.
