A Simple Digestion Method with a Lefort Aqua Regia Solution for Diatom Extraction

Presence of diatoms in tissues has been considered as a significant sign of drowning. However, there are limitations in the present extraction methods. We developed a new digestion method using the Lefort aqua regia solution (3:1 nitric acid to hydrochloric acid) for diatom extraction and evaluated the digestive capability, diatom destruction, and diatoms' recovery of this new method. The kidney tissues from rabbit mixed with water rich in diatoms were treated by the Lefort aqua regia digestion method (n = 10) and the conventional acid digestion method (n = 10). The results showed that the digestive capability of Lefort aqua regia digestion method was superior to conventional acid digestion method (p < 0.01); the structure of diatom remained almost intact; and the recovery of diatom was comparable to the conventional acid digestion method (p > 0.05). The Lefort aqua regia reagent is an improvement over the conventional acid digestion for recovery of diatoms from tissue samples.     

The iteration deficit in responsive regulation: Are regulatory ambassadors an answer?

One reason that regulation is difficult is that repeated encounters between regulator and regulatee are rare. We suggest diplomacy as a model for reconfiguring regulatory institutions in response. Ambassadors for Regulatory Affairs who would be agents for all state regulatory agencies could be based in most large firms and small and medium enterprises that pose unusual regulatory risks. In rural towns, police would be trained as regulatory ambassadors. Just as a US Secretary of State can launch a “diplomatic surge” in Myanmar from 2009, so regulatory surges are possible in market sectors of high risk or high opportunity. We propose strategies of indirect reciprocity as a way in which reciprocity that is only episodic in these strategic ways can promote more general responsiveness. Indirect reciprocity is reciprocity that we do not personally experience, but learn from the experience of a culture. This means that so long as we sustain regulation as a relational as opposed to a purely technocratic process, indirect reciprocity might civilize regulatory compliance in an historical process informed by the theories of Elias and Putnam.     

理性的失落——对"器官异位案"的理性思考

法律对于理性人的假设,使法官在疑难案件的裁判中举步维艰。但任何一个具有正义感的法官都不应屈服于人类的有限理性。突破理论与实践中意识形态的束缚,创造性地适用法律并以此实现个案正义,是法官的必须选择。

对提高政府行政行为的正价值途径的思考

政府行为是依法行使的一种国家行政权力行为,涉及到广大人民群众的根本利益,需要严格地按照规范的工作程序进行,特别是政府的重大行为、原则行为必须按照一定的程序进行,尤其是要按照法律规定的权限行事,在国家法律许可和保障的条件下运行,这样才能确保政府行为实现调控社会的管理职能。     

邓小平关于学习和利用资本主义的方法论分析

在社会主义发展的历史进程中,如何学习和利用资本主义、发展社会主义是一个高难度的课题。邓小平在改革开放和社会主义建设实践中,运用哲学思维,成功地从一般原则和具体方法两个方面解决了学习和利用资本主义、发展社会主义的实践问题,加速了社会主义现代化建设的进程。     

和谐社会中的经济法

本文以社会主义和谐社会构建为背景,阐述了经济法的公平理念是机会公平与结果公平,形式公平与实质公平的统一。在具体制度安排方面,从财政制度、税收制度、社会保障制度、市场竞争制度四个方面进行了论述。     

论罪名定义

罪名定义是揭示罪名概念内涵即犯罪本质特征或主要特征的逻辑方法。我国刑法中罪名定义有三个特点。制定罪名定义的方法是属加种差定义方法。罪名定义是犯罪构成要件的综合,共有六大类型。制定罪名定义时我们应避免犯三种逻辑错误。
