UPLC—MS／MS法测定人血中雪上一枝蒿甲素

目的建立超高效液相色谱-串联质谱（UPLC—MS／MS）法测定人血中雪上一枝蒿甲素含量的方法。方法样品经乙酸乙酯提取后,Ci8柱分离,以0．1％甲酸乙腈-0．1％甲酸水为流动相梯度洗脱,正离子-多反应离子监测模式（ESI＋-MRM）测定雪上一枝蒿甲素,定性定量离子对分别为344．3／58．0、344．3／91．0。结果雪上一枝蒿甲素在3．5～850ug／L-1。范围内与峰面积呈现良好的线性关系（r=-0．9968）,检测限为0．1Iμg／L-1,日内、日间精密度均〈10％,低、中、高三个浓度下准确度（n=5）为97．2％-115．2％,回收率（n=5）为86．6％~89．4％。结论该方法操作简便,结果准确,可作为测定人血中雪上一枝蒿甲素含量的方法。

现代税制下的政府收益最大化:概念阐释

本文通过阐述公共产品的最优供给与政府总的净收益之间的联系来界定现代税制下的“政府收益最大化”,指出现代税制下的“政府收益最大化”是政府为了实现公共利益而优化公共产品供给的结果。“公共产品优化供给”的核心指标是纳税人提前支付了公共产品的生产成本后,在公共产品消费过程中不必二次付费。尽管这种“政府收益最大化”并非特定时空政府经济作为的描述,但是它所建立的规范性判断却可以为现代政府的财政决策提供参考或指导,从而有助于政府更好地服从于公共利益的安排。     

The delisting decision: The case of buyout offer with squeeze-out (BOSO)

In this paper, we exploit the specificity of going-private transactions that are initiated by the historic controlling shareholders (i.e. voluntary delistings). In Continental Europe, the majority of firms that become private do so following a buyout offer with squeeze-out (BOSO); using this mechanism, the controlling shareholder can cash out minorities and take the firm private. We argue that the decision to go private results from a cost–benefit analysis. Moreover, we pay particular attention to the consequences and the related costs of compliance resulting from the passage of the French Financial Security Law (FSL) in 2003. A quantitative study was performed using a unique dataset spanning 1997–2006. This data set consists of 140 French firms, of which 70 were voluntarily delisted via BOSO and 70 were industry-matched control firms. Univariate analysis and logistic regressions support the cost–benefit analysis: when listing benefits decrease because of weak liquidity and/or weak analyst coverage, it seems better for the firm to go private. Furthermore, the inherent characteristics of delisted firms (i.e. performance, leverage, and risk as measured by the beta factor) appear to be important driving factors of delisting. The passage of the FSL has strengthened the impact of these characteristics on the decision to go private. Mature firms that have weak performance and low specific risk and that are not financially constrained by debt will decide to go private because they cannot afford the listing status anymore. Finally, we show that the driving factors of delisting differ according to the identity of the controlling shareholder; specifically, the level of risk appears to be the strongest determinant for family firms, while non-family firms also consider their own financial structure.     

The Establishment of the Philosophy of Comedy in The Cherry Orchard

A. P. Chekhov, known as “the pioneer of modern drama in the 20th century”, is not only a famous Russian anovelist but also an outstanding dramatist. The Cherry Orchard is the author’s last play. In this paper, we made a detailed analysis of the text. First of all, the paper analyzes its “joy in grief” comedy philosophy from the so-called “sadness”. Secondly, the paper discusses the transformation from a real existence to the metaphorical process of “the cherry orchard” in combination with the author’s life. Finally, this paper analyzes the surface structure and deep structure of the play from two aspects of portraits of characters and scenes and reveals the way to establish the philosophy of comedy in this play.     

The Theory on Social Ideal in Eastern Zhou Dynasty

Chinese ancient social ideals theory first appeared in the Eastern Zhou dynasty. They show the longing for a better society of people suffering continuous war in the Warring States era.These doctrines include “Datong” visioned by Book, Benevolence pursued by Mencius, “A small Utopian society” longed by Lao-tse, “D's World” pursued by Zhuang zi, “One World” craved by Mr. Yuchi, “Catholic society” advocated in Lushi-chunqiu. “Sharing the world together and enjoying mutual benefit.” designed by Six Secret Teachings. These doctrines have one thing in common: the rulers of the ideal society are expected to have the public mind , people loving each other and members of the community achieving wealth sharing, so as to ensure the social well-being and harmony. They share similarities with western socialist doctrines laying emphasis on “selfless” and “communism”. Nowadays, the Chinese Dream can absorb many valuable and thoughtful resources from them.     

身份叙事与中国参与北极事务身份建构

国家身份可以划分为总体身份和具体身份,具体身份是总体身份在不同场域的具体投射。作为话语实践的一种形式,叙事则是身份建构的主要机制,它将一系列关于总体身份和具体身份的隐喻以特定逻辑联系在一起。当代中国所追求的总体身份是负责任大国,而这一身份的主要表现则是倡导构建人类命运共同体。这一身份通过领域或功能以及地域两个维度被投射到北极场域,形成了"北极事务的重要利益攸关方"这一具体身份。本文在论述叙事和国家身份形成关系的基础上,重点分析了"北极事务的重要利益攸关方"这一身份隐喻通过叙事被投射到具体场域中的过程。通过叙事,"北极事务的重要利益攸关方"同中国的国际责任、各国的共同利益等话语联系在一起,成为负责任大国身份在北极场域的延伸,成为构建人类命运共同体这一宏观目标的组成部分。     

《儿女英雄传》"第老的"释义商榷

《儿女英雄传》中“第老的”一词表示的排行问题值得进一步商榷和研究。一般认为“第老的”解释为“排行最小”的比较恰当。通过对方言和相关文献的分析研究,可证明“老”为“二”的方言词音记录形式,“第老的”就是“第二的”的解释较为准确。     

略论政府和谐

和谐社会是一个多层面的大系统,政治和谐是和谐社会的一个子系统。政府和谐是政治和谐进而是和谐社会的重要组成部分。和谐社会决定政府和谐,政府和谐又能动地反作用于和谐社会建设。构建和谐社会的成败取决于政府和谐及其程度。政府和谐包括政府外部和谐和政府内部和谐及其互动,通过内外政府和谐的互动,实现政府美的形象和可持续发展。能否构建政府和谐,取决于政府建设、政府自觉、政府自主、政府自律及其程度。
