师范院校就业指导教师职业能力培养的若干问题研究

根据学生就业现实需求和教师能力现状分析,可将师范院校就业指导教师职业能力培养问题分解为三个子课题,并认为:在管理方面,应建立制度化培训考核体系进行职业能力培养综合管理;在专业方面,应以分类化发展的方式培养教师的专精能力;在实效方面,应以校内外密切合作的方式培养教师的实务能力。     

以党的群众路线教育活动推进大学生思想政治教育工作精细化

高校群众路线教育实践活动为高校思想政治教育精细化提供了契机。面对高校在校生数量的连年增加,教育对象的差异性给思想政治教育工作提出了严峻挑战。从思想政治教育体现出的许多新特点来看,学生教育精细化管理的创新是必然趋势。要通过建立健全运行机制、建立信息管理系统,增强精细化思想政治教育的执行力,才能确保高校思想政治教育精细化工作的有效开展。     

中国已经建立起市场经济规律起主导作用的经济体制

经过二十多年的改革开放,中国经济的市场化程度大大提高,各种所有制形式取得了平等的市场地位,生产要素和商品的价格由市场供求决定,企业独立自主地开展生产经营活动,在市场经济的框架下展开各种形式的竞争,追求经济效率的提高和利润最大化.这些都表明中国已经建立起了符合市场经济规律的社会主义市场经济体制.     

试析以人民为中心思想的理论基础——以马克思主义理论为视角

以人民为中心思想是习近平新时代中国特色社会主义理论的重要组成部分,既是对马克思主义理论人民立场的继承与发展,又是紧密结合新的时代特征和实践要求的理论创新成果。中国共产党是马克思主义政党,中国共产党坚持马克思主义理论就必须以人民为中心。中国共产党的初心和使命就是为人民谋幸福,为中华民族谋复兴。中国共产党在中国近现代史上始终践行了马克思主义人民性的理论品格。中国特色社会主义进入新时代后,我国社会的主要矛盾已经变成人民日益增长的美好生活需要和不平衡不充分的发展之间的矛盾,中国共产党作为马克思主义执政党,只有始终坚持以人民为中心,只有始终坚持走中国特色社会主义道路,才能永远代表并最终实现中国人民的根本利益。     

彝文研究的踵武增华——评马锦卫教授《彝文起源及其发展考论》

彝族的文字,是我国古文字体系中一种较为古老的象形文字。关于彝文的起源、彝文的性质、彝文的构形法、彝文的规范、彝文与甲骨文的关系等诸多问题,前辈学者作过比较深人的研究和讨论,尽管如此,留给后人再思考问题依然很多。     

Time Series Modeling of Degradation Due to Outdoor Weathering

Environmental variables have an important effect on the reliability of many products such as coatings and polymeric composites. Long-term prediction of the performance or service life of such products must take into account the probabilistic/stochastic nature of the outdoor weather. In this article, we propose a time series modeling procedure to model the time series data of daily accumulated degradation. Daily accumulated degradation is the total amount of degradation accrued within one day and can be obtained by using a degradation rate model for the product and the weather data. The fitted model of the time series can then be used to estimate the future distribution of cumulative degradation over a period of time, and to compute reliability measures such as the probability of failure. The modeling technique and estimation method are illustrated using the degradation of a solar reflector material. We also provide a method to construct approximate confidence intervals for the probability of failure.     

Discrimination of AR,MA and ARMA time series models

The problem of discrimination between two stationary ARMA time series models is considered, and in particular AR(p), MA(p), ARMA(1,1) models. The discriminant based on the likelihood ration leads to a quadratic form that is generally too complicated to evaluated explicitly. The discriminant can be expressed approximately as a linear combination of independent chi–squared random varianles each with one degree of freedom, the coefficients, of which are eigenvalues of cumbersome matrices. An analytical solution which gives the coefficients approximately is suggested.     

Vector random fields with compactly supported covariance matrix functions

The objective of this paper is to construct covariance matrix functions whose entries are compactly supported, and to use them as building blocks to formulate other covariance matrix functions for second-order vector stochastic processes or random fields. In terms of the scale mixture of compactly supported covariance matrix functions, we derive a class of second-order vector stochastic processes on the real line whose direct and cross covariance functions are of Pólya type. Then some second-order vector random fields in R^d${\mathbb{R}}^d$ whose direct and cross covariance functions are compactly supported are constructed by using a convolution approach and a mixture approach.     

Darling–Erdős limit results for change-point detection in panel data

We wish to test the null hypothesis if the means of N panels remain the same during the observation period of length T. A quasi-likelihood argument leads to self-normalized statistics whose limit distribution under the null hypothesis is double exponential. The main results are derived assuming that the each panel is based on independent observations and then extended to linear processes. The proofs are based on an approximation of the sum of squared CUSUM processes using the Skorokhod embedding scheme. A simulation study illustrates that our results can be used in case of small and moderate N and T. We apply our results to detect change in the “corruption index”.
