素质教育对教师素质的要求

素质教育的实质就是以教师为代表的高素质的人对学生实施的旨在提高学生综合素质的教育 ,教师素质的高低 ,直接决定着素质教育的成败。可以说 ,素质教育的成效是由教师素质决定的。教师的思想政治素质、道德品行素质、科学文化素质、能力素质、身心素质等是素质教育对教师素质的基本要求。为此 ,各级各类学校要切实加强对教师的培养 ,全面提高他们的素质 ,努力完成培养高素质的人才重任。

生态政治化进程中的生存博弈

在西方国家首先出现的生态政治运动促使了西方国家的政治转型,即逐渐走向生态政治模式.始于20世纪80年代的中国改革,致力于维持现存政治形态下的经济突破,虽带来经济的超常规增长,亦不知不觉陷入总想避免又无力回头的"先污染、后治理"状况.频发的生态危机与低效治理模式的"错配"引发的"合法性"危机促使了生态政治化的产生和发展.作为政治形态的系统转型,多元主体间的利益博弈又往往使这一进程面临诸多变数.要准确把握中国生态政治化的演化进程,就必须结合具体的生态危机案例,动态演绎其中的互动利益博弈;即选取博弈主体,定位其角色,描述其博弈策略和技术.最后,在相关结论基础上,对中国生态政治化进程进行总体性描述.     

Construction of Confidence Intervals for the IVIean of a Population Containing Many Zero Values

The likelihood ratio method is used to construct a confidence interval for a population mean when sampling from a population with certain characteristics found in many applications, such as auditing. Specifically, a sample taken from this type of population usually consists of a very large number of zero values, plus a small number of nonzero values that follow some continuous distribution. In this situation, the traditional confidence interval constructed for the population mean is known to be unreliable. This article derives confidence intervals based on the likelihood-ratio-test approach by assuming (1) a normal distribution (normal algorithm) and (2) an exponential distribution (exponential algorithm). Because the error population distribution is usually unknown, it is important to study the robustness of the proposed procedures. We perform an extensive simulation study to compare the percentage of confidence intervals containing the true population mean using the two proposed algorithms with the percentage obtained from the traditional method based on the central limit theorem. It is shown that the normal algorithm is the most robust procedure against many different distributional error assumptions.     

山西黄土CBR的影响分析

在山西省选取5种典型黄土，采用室内试验方法，制备不同击实次数，不同含水量的试件用于CBR值的测定，分析含水量和压实度对黄土填料CBR值的影响，并建立了CBR与含水量的相关关系式。试验结果表明：含水量对CBR值的影响程度最大，在最佳含水量，最大压实度条件下的CBR值最大，含水量越大，击实次数对CBR值的提高效果甚微。随着击实次数的增大，浸水 CBR和不浸水CBR与含水量的相关关系都呈现一定的规律性。     

A Novel Human Error Probability Assessment Using Fuzzy Modeling

Human error is one of the significant factors contributing to accidents. Traditional human error probability (HEP) studies based on fuzzy number concepts are one of the contributions addressing such a problem. It is particularly useful under circumstances where the lack of data exists. However, the degree of the discriminability of such studies may be questioned when applied under circumstances where experts have adequate information and specific values can be determined in the abscissa of the membership function of linguistic terms, that is, the fuzzy data of each scenario considered are close to each other. In this article, a novel HEP assessment aimed at solving such a difficulty is proposed. Under the framework, the fuzzy data are equipped with linguistic terms and membership values. By establishing a rule base for data combination, followed by the defuzzification and HEP transformation processes, the HEP results can be acquired. The methodology is first examined using a test case consisting of three different scenarios of which the fuzzy data are close to each other. The results generated are compared with the outcomes produced from the traditional fuzzy HEP studies using the same test case. It is concluded that the methodology proposed in this study has a higher degree of the discriminability and is capable of providing more reasonable results. Furthermore, in situations where the lack of data exists, the proposed approach is also capable of providing the range of the HEP results based on different risk viewpoints arbitrarily established as illustrated using a real‐world example.     

金融危机下外资银行对我国金融业的影响分析

一、当前金融危机对我国金融业的启示 全球性金融危机使许多国家经济遭受重创，各国金融机构所受冲击更大。同时．旧的国际金融秩序被打破，新的国际金融体系正在建立。在这样的大背景下．我国金融业发展也不可能“独善其身”。改革开放以来．我国金融业不断融入世界金融体系．不可避免地面临全球金融环境变化的影响。但从总体发展看．推动我国金融业发展的动力仍然十分强劲．行业增长趋势不会改变。     

基于Gabor变换的信号降噪方法

介绍了Gabor变换的基本理论，提出了一种基于Gabor变换的降噪方法。该方法首先对信号进行Gabor变换，并选择合适的阈值对Gabor展开系数进行处理，然后对处理后的Gabor展开系数进行Gabor逆变换，从而实现降噪。仿真结果表明，该方法具有很好的降噪效果，为机械故障诊断提供了一种新的思路。

对天津市近期建设规划编制的思考与建议

一、天津市近规编制方法回顾 （一）滚动性近期建设规划 天津市近期建设规划（以下简称“近规”）工作开始较早，在国务院批复的《天津市城市总体规划（1986年～2000年）》中，近规就已经作为一个专项进行编制。自1999年开始，天津采取滚动编制的模式，即每年编制一次后五年的近规。
