Designs with Repeated Measurements on Any Number of Units over Varying Periods

In the usual repeated measurements designs (RMDs), the subjects are all observed for the same number of periods and the optimum RMDs require specified numbers of subjects, usually depending on the number of treatments to be used. In practice, it is sometimes not feasible to meet these requirements. To overcome this problem, alternative designs are suggested where any number of available subjects may be used and they may be observed for different periods. These designs are based on suitable serially balanced sequences which are shown to be optimal. Moreover, besides the usual direct and residual effects, the model considered has an extra term due to the interaction effect between them. The recommended designs are universally optimal in a very general class.     

A class of closeness criteria

A generalized class of closeness criteria for the pairwise comparison of esti¬mators is defined. This class contains an infinite number of members including Pitman's measure of closeness and at least one transitive criterion. Several specific members of the class are examined, and their relationships to Rao concentration and stochastic domination are shown. Graphical and analyti¬cal characterizations are shown for these members of the class. Examples are given which illustrate the behavior of some of these criteria.     

Expanding social health protection in Cambodia: An assessment of the current coverage potential and gaps,and social equity considerations

The Royal Government of Cambodia recently launched its National Social Protection Policy framework to strengthen and expand social security and assistance. To inform social health protection policy, we examine socio-economic survey data and administrative coverage data to assess the coverage potential of existing coverage mechanisms and current gaps; and compare equitable contribution rates. Over 53 per cent of the population currently has no social health protection coverage mechanism, and about 16 per cent of the population who do have access to a mechanism are not yet enrolled. Current expansion efforts focus on the formal employee scheme, primarily benefiting individuals from higher income households. In addition, recent coverage expansion to some informal workers leaves significant gaps, particularly among the informal sector. We find out-of-pocket health care expenditure to be an excessive share of income among lower wealth quintile individuals and conclude they are financially vulnerable. Finally, we illustrate that an equitable approach to individual, monthly health care contributions among the lower three quintiles has a severely limited potential for revenue generation, and collection costs could exceed the amount collected. Therefore, we recommend that vulnerable groups should be exempted from contribution payments as social health protection is expanded.     

Complete moment convergence of moving-average process generated by a class of random variables

In this article, we establish the complete moment convergence of a moving-average process generated by a class of random variables satisfying the Rosenthal-type maximal inequality and the week mean dominating condition. On the one hand, we give the correct proof for the case p = 1 in Ko (2015 Ko, M.H. (2015). Complete moment convergence of moving average process generated by a class of random variables. J. Inequalities Appl. 2015(1):1–9. Article ID 225.[Crossref], [Web of Science ®] , [Google Scholar]); on the other hand, we also consider the case αp = 1 which was not considered in Ko (2015 Ko, M.H. (2015). Complete moment convergence of moving average process generated by a class of random variables. J. Inequalities Appl. 2015(1):1–9. Article ID 225.[Crossref], [Web of Science ®] , [Google Scholar]). The results obtained in this article generalize some corresponding ones for some dependent sequences.     

农村问题研究：后税费时期“农村经营政治”的表现与影响

国家一社会关系视域下的农村基层政治形态在后税费时期出现了新的特点。在基层政权-村干部-村民的权力关系角逐中,干部统制的权威和认受性基础与取消农业税前发生了变化。这种变化是基于新一轮的农村发展政策偏差运行之上,使得“农村经营政治”逐渐凸现,并产生了双重社会后果,其一是农村社区新型贫困,其二是干部权威和认受性受到削弱,对农村社会稳定有很大的侵蚀作用。     

构建市场化邮政普遍服务机制的重要性及应处理的关系

邮政普遍服务是国际公认的准则。随着市场环境的变化 ,原来普遍服务赖以存在的“交叉补贴”格局逐渐消失。本文着重分析了在新的市场环境下建立市场化的邮政普遍服务机制的重要性 ,以及必须处理好普遍服务与专营、城市化、自身商业利益、企业负担等方面的关系。     

Methods for testing subblock patterns

A number of statistical tests have been recommended over the last twenty years for assessing the randomness of long binary strings used in cryptographic algorithms. Several of these tests include methods of examining subblock patterns. These tests are the uniformity test, the universal test and the repetition test. The effectiveness of these tests are compared based on the subblock length, the limitations on data requirements, and on their power in detecting deviations from randomness. Due to the complexity of the test statistics, the power functions are estimated by simulation methods. The results show that for small subblocks the uniformity test is more powerful than the universal test, and that there is some doubt about the parameters of the hypothesised distribution for the universal test statistic. For larger subblocks the results show that the repetition test is the most effective test, since it requires far less data than either of the other two tests and is an efficient test in detecting deviations from randomness in binary strings.     

论哈姆雷特的艺术个性塑造

作为文艺复兴时期人文主义文学发展繁荣的代表 ,莎士比亚之所以在戏剧艺术史上具有重大的意义 ,其艺术形象的个性刻画是极为重要的原因之一。本文认为 ,哈姆雷特的艺术性格具有丰富性与复杂性。它交融着人类涵蕴丰富的历史、文化、社会及其审美心理的幽咽颤栗的诗性。而这一艺术性格所具有的真正的艺术生命、深刻的文化蕴涵和永久的艺术魅力 ,又同这一艺术典型在个性特征与普遍意蕴、内在冲突与心灵矛盾等方面的融汇统一及其艺术化的呈现和表征密切相关。     

委托—代理理论在电力普遍服务管制政策中的应用研究

随着电力体制改革的进行,电力普遍服务的概念也日益受到社会的关注。本文将委托—代理理论应用于电力普遍服务管制问题的研究中。针对电力行业现状,本文分析了参与约束和激励相容约束的实现条件,在对交叉补贴、普遍服务基金和政策性补助等几种电力普遍服务实现机制进行讨论的基础上,提出建立电力普遍服务基金是相对可行的、最有效的解决方案。     

道内之反与道行之周--老庄的道之作用论

对老子庄子之道的自为生机与自动运动过程的规律性进行了探讨。本于老庄道的“无之以为用”的前提,阐释道所以能自本自根,对天地人各界事物发生创化与消解作用,全在于自身是由内在的对待之反所致,即“反者道之动”,使万有事物因“势”运行。在“逝”中“自化”,当“自化”达于相当程度即“远”时,事物便走向反面,完成道的一个周行期。人应体道以生,执道而行,与道俱适,进入周行而运化的自然而然的自由境界。
