Rapid Separation of Organophosphate Pesticides using Micellar Electrokinetic Chromatography and Short‐end Injection,

Organophosphate (OP) pesticides are highly toxic substances and are frequently represented as poisons. In order to qualify and quantify the selected OP pesticides (methyl paraoxon, ethyl paraoxon, methyl parathion, fenitrothion, and ethyl parathion), micellar electrokinetic chromatography and short‐end injection were investigated. This is the first time that this combination has been used to separate OP pesticides. A capillary with 8.5 cm effective length was used, and the analytes were separated within 2.1 min. Separation conditions including buffer (type, pH, and concentration), sodium dodecyl sulfate concentration, and separation voltage were optimized. The limit of detection (LOD) was estimated in the range of 10–20 μM. The OP pesticides spiked in artificial saliva and drinking water gave superior peak profiles, and good average recoveries 95.6% and 62.3%, respectively. Overall, a rapid method with excellent resolution and efficiency was developed and successfully applied in the analysis of potential sample matrixes.     

Response to Criticism: Police Legitimacy,Beyond the Entrenched Niches of Expertise

The purpose of this article is to first re-state the key points of the rejoinder by Cao and Graham. It then proceeds to defend and clarify the arguments that we have made in our article by raising a few misinterpretations by the two reviewers. I end this article with an advice from John Braithwaite 30 years ago that we should nurture the new endeavors in criminology instead of being united against such undertakings.

Disputes, Democracies, and Dependencies: A Reexamination of the Kantian Peace

Militarized interstate disputes are widely thought to be less likely among democratic countries that have high levels of trade and extensive participation in international organizations. We reexamine this broad finding of the Kantian peace literature in the context of a model that incorporates the high degree of dependency among countries. Based on in-sample statistical tests, as well as out-of-sample, predictive cross-validation, we find that results frequently cited in the literature are plagued by overfitting and cannot be characterized as identifying the underlying structure through which international conflict is influenced by democracy, trade, and international governmental organizations. We conclude that much of the statistical association typically reported in this literature apparently stems from three components: (1) geographical proximity, (2) dependence among militarized interstate disputes with the same initiator or target, and (3) the higher-order dependencies in these dyadic data. Once these are incorporated, covariates associated with the Kantian peace tripod lose most of their statistical power. We do find that higher levels of joint democracy are associated with lower probabilities of militarized interstate dispute involvement. We find that despite high statistical significance and putative substantive importance, none of the variables representing the Kantian tripod is associated with any substantial degree of predictive power.     

中国政府绿色采购制度初探

随着国际上循环经济和可持续发展模式的不断发展和演进，政府采购日益重视环境保护和生态平衡，不断朝着与环境更友好、更和谐的方向发展。政府绿色采购在当前环境问题日益严重和政府采购规模不断扩大的形势下，具有重要的理论和现实意义。该文就政府绿色采购的必要性作简要分析研究，并在此基础上提出关于构建中国政府绿色采购制度的几点建议。     

科技法律与科技进步的相互影响与作用

科技进步是科技法产生与发展的基础.科技法律对科技进步的巨大影响,表现在科技法能为科技进步提供一个良好的社会环境,形成激励科技创新的机制,制约政府的短期行为,确保国家和社会的科技投入力度.科技法的这种作用也为15至18世纪中国与西欧科技立法的反差导致科技优势的逆转、19世纪荷兰专利法"立、废、立"的经验教训、20世纪韩国与美国的科技立法对科技与经济发展的显著作用等例所证明.     

在邓小平理论课中怎样实现“进脑”
