对我国电子商务税收问题的探讨

电子商务是一种全新的商务模式,有着与传统商务模式不同的技术和收入特征。文章针对电子商务对现行税收政策、税收制度、税收征管的影响,结合西方国家目前制定的电子商务课税政策,探讨了我国制定电子商务税收政策的原则,最后对我国电子商务税收政策的制定提出了一些建议。     

关于提前介入制度若干问题的探讨

提前介入制度是检察机关履行法律监督职能的重要手段,有其存在的法律依据,在司法实践中也有其必要性．对刑事侦查的质量和刑事诉讼效率的提高越来越凸显其重要作用。提前介入制度与侦查保密制度、回避原则的冲突之处,是可以解决的,这有待在制度的设计上进一步完善。     

浅议我国行政规划的制定程序

作为现代行政的重要手段，行政规划在政府行政中的作用将愈加突显，与之相对应，对行政规划的规制也将愈加重要。而在其规制中，最重要的就是规范行政规划的制定程序。只有规范行政规划的制定程序，才能保证行政规划的合法性与合理性，使行政目标得以实现。     

罗尔斯分配正义及对我国分配问题的启示

罗尔斯的正义论不只是对传统正义观的继承,更是对其的创新和发展。它较为深刻地论述了个人与社会关系这一带有普遍意义的社会基本问题。分配正义是转型期中国社会遇到的核心问题,是诱发各种社会矛盾的根源之一。罗尔斯所提出的解决分配不正义的基本原则和设想,给我们勾画了一个自由又平等的社会愿景。其《正义论》可以说给我们提供了一个解决社会不正义的极其优化的解决方案。     

论电子商务法的功能等同原则

通过对电子商务法功能等同原则基本内涵的剖析以及国际国内电子商务法对功能等同原则的体现，阐述了为什么只有电子商务法领域才有功能等同原则、功能等同原则是如何与其它原则一同构成电子商务法基本原则体系的、功能等同原则对立法和司法实践具有什么指导意义，并最终得出功能等同原则不应该长久地作为电子商务法的基本原则的结论。     

内燃机原理实验的教学改革实践

阐述了实验教学的重要性,并从教学内容、思路、教学队伍建设及教学的各个环节介绍了<内燃机原理>实验的改革,提高了学生独立解决问题的能力.     

社会公正与我国和谐社会之构建

关于社会公正的理论讨论大致形成了三种理论模式。在我国，作为和谐社会建构的首要价值原则，社会公正得到了普遍的认可。但由于种种原因，社会公正一直没有在人们的社会政治生活中得到完整且真正的体现。因此如何遏制社会不公正现象，维护社会公正，进而顺利实现社会主义和谐社会的伟大建构，已成为我们当今十分紧迫的任务。     

MODELING THE LIFETIME OF LONGITUDINAL ELEMENTS

In the study of the stochastic behaviour of the lifetime of an element as a function of its length, it is often observed that the failure time (or lifetime) decreases as the length increases. In probabilistic terms, such an idea can be expressed as follows. Let T be the lifetime of a specimen of length x, so the survival function, which denotes the probability that an element of length x survives till time t, will be given by S_T (t, x) = P(T > t/α(x), where α(x) is a monotonically decreasing function. In particular, it is often assumed that T has a Weibull distribution. In this paper, we propose a generalization of this Weibull model by assuming that the distribution of T is Generalized gamma (GG). Since the GG model contains the Weibull, Gamma and Lognormal models as special and limiting cases, a GG regression model is an appropriate tool for describing the size effect on the lifetime and for selecting among the embedded models. Maximum likelihood estimates are obtained for the GG regression model with α(x) = cx^b . As a special case this provide an alternative to the usual approach to estimation for the GG distribution which involves reparametrization. Related parametric inference issues are addressed and illustrated using two experimental data sets. Some discussion of censored data is also provided.     

刑事和解的价值评析及完善机制之构想

刑事和解是刑事司法改革的一种尝试,实践以来,凸显其效率功能,符合新时期司法的社会需求,同时在操作上社会民众对其亦存有不少质疑,但从司法效率、社会管理又普惠民生的角度来看,有值得探讨不断完善的价值,必须进一步确立科学的指导原则,规定案件的适用范围,明确适用条件,完善相关机制。     

Estimating utility functions using generalized maximum entropy

This paper estimates von Neumann and Morgenstern utility functions using the generalized maximum entropy (GME), applied to data obtained by utility elicitation methods. Given the statistical advantages of this approach, we provide a comparison of the performance of the GME estimator with ordinary least square (OLS) in a real data small sample setup. The results confirm the ones obtained for small samples through Monte Carlo simulations. The difference between the two estimators is small and it decreases as the width of the parameter support vector increases. Moreover, the GME estimator is more precise than the OLS one. Overall, the results suggest that GME is an interesting alternative to OLS in the estimation of utility functions when data are generated by utility elicitation methods.
