专业性——新基础教育课程理念的历史性缺失及其超越

今日中国仍处于现代化进程之中,现代化社会的实质内容和特征是专业性,现代教育教学活动的专业性仍然也是其主要特征。课程作为现代教育教学活动的蓝本和方案,无疑也应该把其专业性特征放在首位。新基础教育课程表现出明显的淡专业性、非专业性和去专业性,这是新基础教育课程的历史性越位的具体表现,造成的是新基础教育课程的历史性缺失。解决这一越位和缺失问题的根本出路在于历史性地回归和超越课程的专业性。     

博弈论框架下的信用缺失探析

运用博弈论探析了我国在完善市场经济中的信用缺失问题 ,认为信用缺失的原因在于经济主体对未来缺乏足够的信心 ,合同 (战略 )的执行机制不力及政府宏观经济政策的动态不一致 ,并据此提出解决措施。     

防治信用缺失,优化信用环境

信用是现代市场经济的基石,其本质是一种债权债务关系。目前,我国信用体系的制度基础十分脆弱,信用环境不 良,信用缺失现象普遍存在,已严重冲击了正常的市场经济秩序,给经济发展带来了不可估量的损失。因此,如何优 化信用环境、防治信用缺失,已成为我国面临的一个重要课题。     

Propagation of Uncertainty in Risk Assessments: The Need to Distinguish Between Uncertainty Due to Lack of Knowledge and Uncertainty Due to Variability

In quantitative uncertainty analysis, it is essential to define rigorously the endpoint or target of the assessment. Two distinctly different approaches using Monte Carlo methods are discussed: (1) the end point is a fixed but unknown value (e.g., the maximally exposed individual, the average individual, or a specific individual) or (2) the end point is an unknown distribution of values (e.g., the variability of exposures among unspecified individuals in the population). In the first case, values are sampled at random from distributions representing various "degrees of belief" about the unknown "fixed" values of the parameters to produce a distribution of model results. The distribution of model results represents a subjective confidence statement about the true but unknown assessment end point. The important input parameters are those that contribute most to the spread in the distribution of the model results. In the second case, Monte Carlo calculations are performed in two dimensions producing numerous alternative representations of the true but unknown distribution. These alternative distributions permit subject confidence statements to be made from two perspectives: (1) for the individual exposure occurring at a specified fractile of the distribution or (2) for the fractile of the distribution associated with a specified level of individual exposure. The relative importance of input parameters will depend on the fractile or exposure level of interest. The quantification of uncertainty for the simulation of a true but unknown distribution of values represents the state-of-the-art in assessment modeling.

A note on testing the regression functions via nonparametric smoothing

The authors present a consistent lack‐of‐fit test in nonlinear regression models. The proposed procedure possesses some nice properties of Zheng's test such as the consistency, the ability to detect any local alternatives approaching the null at rates slower than the parametric rate. What's more, for a predetermined kernel function, the proposed test is more powerful than Zheng's test and the validity of these findings is confirmed by the simulation studies and a real data example. In addition, the authors find out a close connection between the choices of normal kernel functions and the bandwidths.

谈海德格尔的“此在之忧”

在对技术的追问之中,海德格尔发现了技术之本质,他溯源而上寻得了现代技术之本质———＂座架＂。在座架中起支配作用的乃是一种命运,此命运把人带向一种可能性的边缘,即一味地去追逐、推动那种在订造中被解蔽的东西,并且从那里采取一切尺度。由于人被带到了上述这种可能性的边缘,人便从根本上受到了这种命运的危害。海德格尔说认为,如果命运以座架方式运作,那么命运就是最高的危险了。这种危急的情形着实让海德格尔深感忧虑,他深深地为此在而忧。     

在国际贸易中我国粮食产业定价权分析——基于粮食产业链的研究视角

随着我国粮食市场开放程度的提高,我国粮食产业的各个领域都受到国际贸易市场的强烈冲击。由于国内粮食生产、加工、流通各环节的企业对粮食国际贸易定价权的缺失,导致粮食产业整体利益受损。从粮食产业链的角度对中国粮食参与国际贸易定价权缺失情况进行分析,并提出改进对策,以在市场开放的前提下提高我国粮食产业的竞争力。
