转轨经济理论与国有企业改革

转轨经济特指计划经济向市场经济过渡的经济。新制度经济学与福利经济的相关理论为我国经济转轨时期国有企业改革提供了思路。国有企业的改革应采用渐进的改革方式 ,改革的着眼点在于大力发展非国有经济 ,以改变经济的体制结构 ,壮大非国有经济 ,为国有经济的改革缓解压力。     

Some results on optimality in models with heteroscedastic errors from partial optimum designs

This paper studies optimum designs for linear models when the errors are heteroscedastic. Sufficient conditions are given in order to obtainD-, A- andE-optimum designs for a complete regression model from partial optimum designs for some sub-parameters. A result about optimality for a complete model from the optimality for the submodels is included. Supported by Junta de Andalucía, research group FQM244.     

课堂教学质量评价标准构建方法新探

构建课堂教学评价的标准必须贯彻现代教学评价的核心思想。在课堂教学质量内涵分析的基础上设计问卷,通过调查及分析初步共同构建出评价的指标系统,然后通过对指标系统进行主成分分析以确定评价的综合指标与评价模型。

A “brer rabbit” case for reverse mandated benefits

Reverse mandated benefits is a government-mandated policy that requires employees to provide their employers with benefits that workers would not provide otherwise. Of course, only those benefits would be mandated that are worth more to employers than they cost, as determined by political authorities. My case for such a policy argues that it is at least as sensible as policies mandating that employers provide benefits to their employees that would not be provided otherwise.     

Intertemporal choice under timing risk: An experimental approach

This paper investigates how individuals evaluate delayed outcomes with risky realization times. Under the discounted expected utility (DEU) model, such evaluations depend only on intertemporal preferences. We obtain several testable hypotheses using the DEU model as a benchmark and test these hypotheses in three experiments. In general, our results show that the DEU model is a poor predictor of intertemporal choice behavior under timing risk. We found that individuals are averse to timing risk and that they evaluate timing lotteries in a rank-dependent fashion. The main driver of timing risk aversion is nothing but probabilistic risk aversion that stems from the nonlinear treatment of probabilities.     

从梁启超文化思想变迁看中国文化前景

梁启超是近代中国集中国现代化变革的先驱者和文化保守主义运动肇基人于一身的复杂人物，与多变的时代一样，其文化思想也几经变迁，他处心积虑几十年探索中西文化问题、传统与现代化问题，给后人提供了极富价值的理论思考。中国文化的前景必然是选择现代化，一方面它将最大限度地保持自己的民族特色，另一方面最大限度且毫无条件地吸收一切先进的东西，实现创造性的综合与再铸。     

PES-C,(PP/Bis-T)PES的次级松驰与转变

描述了酚酞型聚芳醚砜(PES-C)的次级松驰和转变与其结构的关系.TBA和动态力学实验结果表明:PES-C及其共聚物(PP/Bis-T)PES分别在0～50℃和-100℃附近呈现出两个次级松驰峰;双酚T单元的引入导致了PES-C在0～50℃之间的次级松驰位置改变.证实了Cardo侧基的存在对-100℃的次级松驰有较大的贡献.     

"V有"式"V""有"之关系及相关问题

从“V有”句式的研究入手,重点对“V有”中“V”的特征、“V”和“有”之间的关系进行了分析,给出了“V”的测试格式。同时,认为“V有”是一种表示结果态的动态关系,其中的“有”丧失了独立的表义功能,变成了一个附加成分。
