Review of analytical techniques for arson residues

Arson is a serious crime that affects society through cost, property damage, and loss of life. It is important that the methods and technologies applied by fire investigators in detection of evidence and subsequent analyses have a high degree of reliability, sensitivity, and be subject to rigorous quality control and assurance. There have been considerable advances in the field of arson investigation since the 1950s. Classification of ignitable liquids has been updated to include many new categories due to developments in the petroleum industry. Techniques such as steam or vacuum distillation and gas chromatography (GC) with flame ionization detection that may have been considered acceptable--even a benchmark--40 years ago, are nowadays generally disfavored, to the extent that their implementation may almost be considered as ignorance in the field. The advent of readily available mass spectrometric techniques has revolutionized the field of fire debris analysis, increasing the degree of sensitivity and discrimination possible considerably. Multi-dimensional GC--particularly GC x GC--while not yet widely applied, is rapidly gaining recognition as an important technique. This comprehensive review focuses on techniques and practices used in fire investigation, from scene investigation to analysis.     

和谐社会理念中的群体性事件及处置

群体性事件是当前我国的社会矛盾之一,是社会不和谐的特有反映。考察近几年群体性事件发生的数量和社会关注程度,以“三农”问题为核心的现代农民或农村问题仍然是主导我国群体性事件的主要方面,另外,就业、金融和贫富差距等问题也经常引发群体性事件。在构建和谐社会的背景下处置群体性事件,应重新确立决策观念,理性理解事件的引发原因,并注意处置中原则的刚性和方法的柔性的有机结合。

论增强党的阶级基础和扩大党的群众基础的辩证统一--学习党的十六大精神的体会

党的十六大报告提出,中国共产党是中国工人阶级的先锋队,同时是中国人民和中华民族的先锋队,这是在党的性质上体现了党的阶级基础和群众基础的统一.第二个先锋队是第一个先锋队的必然要求和题中应有之义,是继承和创新的统一.党的十六大报告提出,重点在工人、农民、知识分子、军人、干部中发展党员,同时吸收其他社会阶层的先进分子入党,这是一个完整、统一的方针,既避免了历史上的关门主义,又同"全民党"划清了界限."两个基础"不能分离,只顾一方面,不顾另一方面,都不利于党的建设和实现党的奋斗目标.     

中国现代化进程中的大众文化与青年社会化

作为现代化的文化逻辑,世俗化已经成为中国社会发展进程中的必然现象,大众文化作为世俗化的一种独特表现形式,对于青年社会化悖论性地展示出其双重面相。为了防止大众文化的阴暗面相的偏激化以及文化堕距现象可能带来的严重后果,文化创新已经成为青年社会化的一种时代呼唤。

The Effect of “Thin Ideal” Television Commercials on Body Dissatisfaction and Schema Activation During Early Adolescence

The purpose of the study was to investigate the effect of viewing televised images of female attractiveness on the body dissatisfaction of young adolescent girls and boys. Adolescents (160 females and 197 males) aged 13–15 years viewed either 20 commercials containing idealized female thin images or 20 nonappearance television commercials. Body dissatisfaction was measured before (Time 1), immediately following (Time 2), and 15 min after (Time 3) commercial viewing. Appearance-schema activation was assessed using a word-stem completion task. Girls, but not boys, who viewed the appearance commercials reported significantly higher body dissatisfaction at both Times 2 and 3 compared with the nonappearance condition. Participant age had no effect. Both girls and boys in the appearance condition reported greater schema activation, but appearance schematicity did not moderate the commercial effect. The results support the general hypothesis that televised images of attractiveness lead to increased body dissatisfaction and schema activation for girls as young as 13 years old.     

食品安全谣言群体性侵权之民事救济研究--以微博谣言为例

食品安全谣言侵权具有与其他大规模侵权案件相似的特性,民事实体救济方式自身的优越性也使得食品安全谣言侵权损害赔偿问题能够得到有效解决。同时,如果将民事救济与我国大规模侵权案件的诉讼方式与国外集体诉讼制度相结合,能够解决此类案件的程序难题。最终形成在此类案件的解决中采用公益诉讼,并建议由政府设立基金对赔偿不足的部分进行补充的解决方式。
