CeO2／蛇纹石体系对饮用水的脱氟行为研究

本文探讨了利用均相沉淀法制备的二氧化铈的脱氟行为,并利用蛇纹石作为载体,对CeO2/蛇纹石体系的除氟行为及最佳条件进行了进一步的研究,结果表明：均相沉淀法得到的二氧化铈除氟效率高,除氟容量可达11.76mg/g。以二氧化铈;蛇纹石为1：10的混合体系的除氟容量大大高于其他方法处理过的蛇纹石体系,其附近氟容量达到0.568mg/g。     

Decomposing the predictive performance of the moving average trading rule of technical analysis: the contribution of linear and non-linear dependencies in stock returns

The main purpose of this work is to decompose the predictive performance of the moving average (MA) trading rule and find out the portion that could be attributed to the possible exploitation of linear and non-linear dependencies in stock returns. Data from the General Index of the Athens Stock Exchange, from the Standard and Poor-500 Index of the New York Stock Exchange and from the Austrian Traded Index of the Vienna Stock Exchange are filtered by linear filters so as the resulting simulated ‘returns’ exhibit no serial correlation. Applying MA trading rules to both the original and the simulated indices and using a new statistical testing procedure that takes into account the sensitivity of the performance of the trading rule as a function of the length of the MA it is found that the predictive performance of the trading rule is clearly weakened when applied to the simulated indices indicating that a substantial part of the rule's predictive performance is due to the exploitation of linear dependencies in stock returns. This weakening is uneven; in general the shorter the MA length the more pronounced the attenuation.     

A Corrected Plug-in Method for Quantile Interval Construction Through a Transformed Regression

We propose a corrected plug-in method for constructing confidence intervals of the conditional quantiles of an original response variable through a transformed regression with heteroscedastic errors. The interval is easy to compute. Factors affecting the magnitude of the correction are examined analytically through the special case of Box–Cox regression. Monte Carlo simulations show that the new method works well in general and is superior over the commonly used delta method and the quantile regression method. An empirical application is presented.     

Identification of arma models with non-gaussian innovations

The problem of modelling time series driven by non-Gaussian innovation has been considered recently by Li and McLeod (1988). In this paper we have discussed the problem of identification of ARMA models with non-Gaussian innovations. Simulation experiments are used to study the applicability of theoretical results.     

企业组织创新与生产率关系的实证研究：以纺织业为例的讨论

本文结合国际创新实证研究新动态,在将创新定义扩展的基础上,以纺织业为例,分析组织创新对于企业生产率的影响。实证研究表明,在企业分规模、分经济类型和分地区的情况下,组织创新对于企业生产率的提高具有显著的影响,只是影响程度各有不同。因此,促进企业组织创新,拓展对创新观念的认识,从而提高企业生产率是应当考虑的企业增长路径之一。     

论文化素质教育与人才创新素质的培养

大学文化素质教育是一种创新意识的教育,大学文化素质教育可以有效地促进人才的创新思维.文化素质教育与科技创新教育有着异曲同工之妙,二者都离不开想象力,在创作灵感上都有相似性,二者都具有渗透性.     

论中国共产党建党理论的创新

实践证明,党的建设是我们党克敌制胜的一大法宝,而建党理论的创新是前提。中国共产党把马克思列宁主义建党理论同中国实际相结合,提出适合中国国情的党的建设理论,反映了时代的需要,全面体现了党的先进性,增强了党的凝聚力和战斗力。学习掌握这些经验,对于我们坚持新时期党的建设纲领有着重要意义。     

从创新教育的角度谈高校考试改革

高校考试现状不尽理想,不利于创新型人才的培养。考试内容、形式必须改革,应从单一的偏重对知识考察的笔试型,改变为对学生综合素质、创新能力和基本知识的综合考评。在改革的思路和方法上,笔者提出了建立人才评价体系中需要研究和探索的新课题。     

中华传统美德的个体性展示

中华民族传统美德是中华民族的优秀遗产,需要中华民族一代一代人不断传扬下去。在这个过程中,社会全方位的美德倡导播撒,是个体展示的最佳环境和前提,同时又是个体展示的机遇。但社会展示只是一个形式和要求,社会展示要通过一个个个体展示落到实处,个体性展示才是具体可视和可操作性的,是社会展示的承载,没有这个承载,社会弘扬与展示只是一个空壳,无根无基。由此,强化个体性展示,对个体性展示提出更高更具体要求,是中华民族传统美德弘扬与践行的根本所在。     

基于信息经济学下科技期刊发展的创新研究

科技期刊的工作主体是信息。信息作为一种商品,是具有经济属性的。本文从信息、信息经济学的概念入手,浅述了科技期刊的信息属性,指出科技期刊也是从属于信息产业的范畴,在此基础上,提出了科技期刊发展的创新策略。
