Preface

Different from traditional tax audit, supervision with self-audit is a combination of audit by the taxpayer himself and audit by the tax authority. This paper mainly studies a taxpayer’s optimal policy of tax evasion under supervision with self-audit and its related properties, in order to deduce some effective suggestions and theoretical bases to restrain tax evasion. Assuming that only a certain proportion of evaded tax can be discovered when the audit is executed, the authors first formulate a static model with self-audit. This model is divided into two stages. At the first stage, taxpayers declare their taxes, then the tax authority chooses audit objects, based on a known probability, and announces the result; if the taxpayer is chosen, he will enter the second stage, during which he has a chance to pay the evaded tax and the corresponding late fees and then is audited by the tax authority. The authors show the existence and uniqueness of the optimal amount of tax evasion at the first stage and the optimal proportion to self-expose at the second stage. The authors also discuss the related properties of the interior solution, and do elasticity analyses on some parameters. Besides, the authors extend the static model into the corresponding two-period model, and study the existence and uniqueness of the solution of the extended model. Finally, under the assumption that tax evasion can only be discovered with a certain probability when the audit is executed, the authors formulate another static model with self-audit and investigate its properties.

《雷雨》与祈雨仪式--曹禺剧作《雷雨》的文化学阐释

曹禺的《雷雨》之所以具有经久不衰的文化魅力并深受作者自己的喜爱,一个未被人们发掘出来的原因是它再现了一个古老的原型——祈雨仪式。在无意识的驱使下,曹禺以现代话剧的形式把古老的祈雨仪式再现在人们面前,不仅让人们重温了祈雨仪式中蕴涵的人类文化精神,也为人们树立了一个在人生旅途中必须不断审视自我、拯救自我、完善自我的范例。

论奎因对模态逻辑的批判

模态逻辑一经产生，就遭到奎因的质疑。奎因认为，模态概念无论在逻辑上还是在哲学上其正确性都值得怀疑。他甚至认为模态逻辑是多余的，应予以抛弃。通过对奎因批判模态逻辑的背景和理论进行分析，章认为奎因对模态逻辑的批评在观念上和论证上都存在缺陷，因此奎因的批判是不能成立的。
