自由美丽人格的培育—蔡元培德育思想解读

蔡元培先生认为,要培养自由美丽的人格,首先要通过军国民教育、实利主义、公民道德教育、世界观教育和美育来完成从现实世界到实体世界过渡的外向自由和内向自由的双重结合,同时实现"思想自由,兼容并包"的大学教育改革。现今德育也应该借鉴蔡元培先生的理念,重视"自由"在德育中的积极意义,在德育的实践中坚持"思想自由,兼容并包"的教育理念,结合德育的教育内容满足大学生的心理需求,使其主体性和个性得以积极发挥。     

“霍山现象”中的民营企业研究

作为国家级贫困县的霍山县,其工业经济在短短的十几年间奇迹般地崛起,被经济学界称之为“霍山现象”、“霍山模式”。霍山民营企业对“霍山现象”的形成起关键性作用。本文通过对霍山民营企业的调查研究,分析了促进霍山民营企业成长的几个重要因素,并剖析了民营企业在投资环境、治理结构及融资等方面存在的问题,提出了进一步发展民营企业的对策建议。     

语言模因和认知隐喻

语言是传递信息的工具,模因的模仿、复制、传播可以通过语言得以有效的实现,而另一方面,隐喻是语言新的意义产生的根源,因此模因的生存和发展离不开隐喻。本文以认知隐喻为研究对象,运用模因理论,分析认知隐喻的模因现象、模因特征以及模因传播,认为模因借助于隐喻生成和发展,而隐喻又依附于模因发展和传播,两者相互依赖,共同发展。     

从股票发行与上市价格的影响因素看我国股市IPO抑价现象的原因

目前,在我国股票市场上一直存在着新股发行价低于上市价格的抑价现象,其主要原因是股市发行与交易市场参与者之间信息不对称。应加速完善上市公司信息披露机制,提高信息的真实性、及时性以及投资行为的理性化程度,借助信息和资金优势带动股票市场价格保持在合理且相对平稳的范围内。只有这样,股票市场价格才会更加清晰的反映出公司实际投资价值,发行价与上市价间的差距也会逐步降低。     

Information in generalized method of moments estimation and entropy-based moment selection

In this paper, we make five contributions to the literature on information and entropy in generalized method of moments (GMM) estimation. First, we introduce the concept of the long run canonical correlations (LRCCs) between the true score vector and the moment function f(_vt,_θ0)$f(v_t,{\theta }_0)$ and show that they provide a metric for the information contained in the population moment condition E[f(_vt,_θ0)]=0$\mathrm{E}[f(v_t,{\theta }_0)]=0$. Second, we show that the entropy of the limiting distribution of the GMM estimator can be written in terms of these LRCCs. Third, motivated by the above results, we introduce an information criterion based on this entropy that can be used as a basis for moment selection. Fourth, we introduce the concept of nearly redundant moment conditions and use it to explore the connection between redundancy and weak identification. Fifth, we analyse the behaviour of the aforementioned entropy-based moment selection method in two scenarios of interest; these scenarios are: (i) nonlinear dynamic models where the parameter vector is identified by all the combinations of moment conditions considered; (ii) linear static models where the parameter vector may be weakly identified for some of the combinations considered. The first of these contributions rests on a generalized information equality that is proved in the paper, and may be of interest in its own right.     

关于法治建设表层化问题研究

中国法治建设进程中存在着法治建设表层化问题,表现为注重外部形式的法律条文和制度建设,轻视法治理念建设,这阻碍了法治建设的实质进展,笔者从文化、经济、政治三角度分析了法治建设表层化的原因,进而提出了克服法治建设表层化的具体途径。     

A new higher-order weak approximation scheme for stochastic differential equations and the Runge–Kutta method

The authors report on the construction of a new algorithm for the weak approximation of stochastic differential equations. In this algorithm, an ODE-valued random variable whose average approximates the solution of the given stochastic differential equation is constructed by using the notion of free Lie algebras. It is proved that the classical Runge–Kutta method for ODEs is directly applicable to the ODE drawn from the random variable. In a numerical experiment, this is applied to the problem of pricing Asian options under the Heston stochastic volatility model. Compared with some other methods, this algorithm is significantly faster. This research was partly supported by the Ministry of Education, Science, Sports and Culture, Grant-in-Aid for Scientific Research (C), 15540110, 2003 and 18540113, 2006, the 21st century COE program at Graduate School of Mathematical Sciences, the University of Tokyo, and JSPS Core-to-Core Program 18005.     

旅游原理基本命题研究

旅游并非自古就有,只有在市场经济发展到一定阶段才会产生。旅游现象表现为“经济外壳”和“文化内核”,由此导致经济和文化两类关系和现象。这些现象交叉、重叠、遮蔽并反映在社会综合现象中,从中揭示各种现象的内在联系、结构、形态。
