Some new constructions of circular balanced repeated measurements designs

Repeated measurements designs are widely used in medicine, pharmacology, animal sciences, and psychology. In this article, some infinite series are developed to generate the balanced repeated measurements designs for p (periods) even. For p odd, construction procedures are also described. Catalogues of the proposed designs are also presented for p = 5, 7, 9, when v ≤ 100.     

Testing variance components in balanced linear growth curve models

It is well known that the testing of zero variance components is a non-standard problem since the null hypothesis is on the boundary of the parameter space. The usual asymptotic chi-square distribution of the likelihood ratio and score statistics under the null does not necessarily hold because of this null hypothesis. To circumvent this difficulty in balanced linear growth curve models, we introduce an appropriate test statistic and suggest a permutation procedure to approximate its finite-sample distribution. The proposed test alleviates the necessity of any distributional assumptions for the random effects and errors and can easily be applied for testing multiple variance components. Our simulation studies show that the proposed test has Type I error rate close to the nominal level. The power of the proposed test is also compared with the likelihood ratio test in the simulations. An application on data from an orthodontic study is presented and discussed.     

The effect of non-normality on estimating the variance of the combined ratio estimate in complex surveys

The performance of the balanced half-sample, jackknife and linearization methods for estimating the variance of the combined ratio estimate is studied by means of a computer simulation using artificially generated non-normally distributed populations.

The results of this investigation demonstrate that the variance estimates for the combined ratio estimate may be highly biased and unstable when the underlying distributions are non-normal. This is particularly true when the number of observations available from each stratum is small. The jack-     

基于人体膳食均衡视角下的我国果蔬消费趋势预测与结构优化

水果和蔬菜是为人体提供矿物质、维生素、膳食纤维等营养元素的重要农产品,我国居民饮食中普遍存在着能量相对过剩、果蔬摄入量不足的问题。以人体膳食均衡为研究视角,研究我国果蔬消费趋势和结构优化问题,结果表明：按照当前的消费趋势发展,我国居民营养摄入不足与过剩同在的问题依然无法得到解决;我国政府在制定水果和蔬菜战略布局的决策中,应综合考虑人体的膳食营养均衡和未来市场营养需求,以实现我国果蔬产业布局优化;消费者在进行水果和蔬菜消费购买行为时,应在营养膳食均衡的基础上进行合理消费。     

Recent developments in D-optimal designs

In the paper, some issues concerned with the determining spring balance weighing designs satisfying the criterion of D-optimality under the assumption measurement errors are uncorrelated and they have the same variances are discussed. In addition, highly D-efficient spring balance weighing designs are also considered. Some conditions under which any spring balance weighing design is regular D-optimal or highly D-efficient are proved. What is more, new construction methods of regular D-optimal and highly D-efficient spring balance weighing designs are presented.

中国经济社会协调发展的经济社会学分析

经济社会协调发展是经济社会学的一个基本观点,经济社会学研究的一个重要目的和归宿点是为了促进经济社会的协调发展。深入研究分析科学发展观中的新表述、新思想、新观念、新目标、新要求,科学发展观就是一种经济社会协调和谐发展的理论,而其中所蕴涵的＂一核心四维度（价值核心、内容维、空间维、时间维、方法维）＂系统结构,就体现了经济社会学理论中系统观、时空观、进程观的有机统一,对经济社会发展协调发展理论进行了重大创新和发展。     

论毛泽东的区域经济均衡发展战略——纪念毛泽东诞辰120周年

实现区域均衡协调发展是中国共产党不懈追求的奋斗目标.毛泽东作为党的第一代领导集体的核心,从新中国建立到党的十一届三中全会的30年时间里,根据当时的中国国情和国际形势制定并实施了区域经济均衡发展战略,主张重点发展内地工业,通过均衡布局,实现共同富裕..这一战略既取得了一定的成就,但也付出了一定的代价.它是历史、时代和制度的产物,我们要辩证看待,它对今天仍具有重要启示和借鉴意义.     

中国义务教育均衡发展的新时代特征与治理路径——基于“五大发展理念”的思考

中国义务教育发展已进入新时代。在创新、协调、绿色、开放、共享"五大发展理念"主导下,义务教育要体现新时代的特征,寻求新的治理路径,从多方面促进均衡发展。其中应致力于五个方面：推动义务教育"创新发展",强调驱动力、内涵式、立体化;推动义务教育"协调发展",注重整体性、互补性、特色化;推动义务教育"绿色发展",重视生态化、可持续性、生命关怀;推动义务教育"开放发展",加强国际化、合作化、包容性;推动义务教育"共享发展",力求公平性、科学性、多元化。
