中国古代均平文化论纲

在中国古代社会,平均观念渗透在中国传统文化的各个思想领域,是各种政治思想、社会思想、伦理思想乃至经济思想的重要文化支点。均平文化的基本内涵,包括政治平均、社会平均、经济平均、均平之德等几个最基本的方面。均平作为一种文化,它的思想价值在于追求社会的和谐与均衡。这种文化,还被赋予了天地自然之德的自然属性,是人对自然德性的效法,因此有着天经地义的正当性。     

陶瓷文化与景德镇陶瓷文化旅游

景德镇作为享誉世界的千年瓷都,拥有丰富的陶瓷文化资源,具有发展陶瓷文化旅游的独特优势。然而,陶瓷文化资源优势并未转化为陶瓷文化旅游的竞争优势。为大力发展景德镇陶瓷文化旅游,需整合陶瓷文化资源,挖掘陶瓷文化内涵,设计精品旅游路线,完善特色休闲娱乐,强化国际营销,加强旅行社和导游队伍建设。

中国工业贸易保护水平与结构的估算与分析

利用作者编制的一整套跨部门和时间序列的数据库 ,对中国 1992年以来工业贸易保护的水平和结构进行的测算 (包括名义关税率、非关税壁垒频数和有效保护率 )和分析表明 :中国贸易保护的基本特征是平均水平较高 ,而且在结构上易变而分散 ;有效保护率的水平和结构比名义保护率更高而离散 ,鼓励下游行业生产的倾向十分明显 ;以配额和许可证等数量限制为核心的非关税壁垒依然较高 ;关税和非关税措施之间多呈现出互补而非替代的关系。随着加入 WTO的进程 ,中国在贸易自由化方面采取了更为激进的改革 ,使贸易的扭曲程度和结构有了显著的改善 ,增强了贸易的中性     

An EWMA chart for monitoring process mean

In the statistical process control literature, there exists several improved quality control charts based on cost-effective sampling schemes, including the ranked set sampling (RSS) and median RSS (MRSS). A generalized cost-effective RSS scheme has been recently introduced for efficiently estimating the population mean, namely varied L RSS (VLRSS). In this article, we propose a new exponentially weighted moving average (EWMA) control chart for monitoring the process mean using VLRSS, named the EWMA-VLRSS chart, under both perfect and imperfect rankings. The EWMA-VLRSS chart encompasses the existing EWMA charts based on RSS and MRSS (named the EWMA-RSS and EWMA-MRSS charts). We use extensive Monte Carlo simulations to compute the run length characteristics of the EWMA-VLRSS chart. The proposed chart is then compared with the existing EWMA charts. It is found that, with either perfect or imperfect rankings, the EWMA-VLRSS chart is more sensitive than the EWMA-RSS and EWMA-MRSS charts in detecting small to large shifts in the process mean. A real dataset is also used to explain the working of the EWMA-VLRSS chart.     

Explicit analytical solutions for ARL of CUSUM chart for a long-memory SARFIMA model

This paper aims to derive explicit analytical solutions for Average Run Length (ARL) of CUSUM chart for the SARFIMA(P,D,Q)_S process with exponential white noise. Measurement of performance was done with the ARL in terms of percentage error and CPU time. The results obtained from the explicit formulas were compared focusing on the performance using the numerical integral equation (NIE) method. Both methods had similarly excellent agreement with the percentage error at less than 0.25%. Meanwhile, the explicit formulas consumed less CPU time than the NIE method. It is clear that the explicit formulas are a good alternative in real applications.     

收入、预期寿命和社会养老保险收入再分配效应

本文在考虑职工基本养老保险典型不同缴费基数参保者寿命存在异质性的情况下,通过内部收益率的计算考察典型不同缴费基数参保者之间的养老金收入再分配效应。首先根据省级宏观截面数据估计了职工基本养老保险典型不同缴费基数参保者退休时的平均余命,再据此分别计算和比较不同参保群体的内部收益率。 研究发现职工基本养老保险制度总体上呈现微弱的正向收入再分配效应。虽然低缴费基数参保者内部收益率略高于中、高缴费基数参保职工,但其内部收益率因相对较短的寿命而大大降低。这也提醒政策制定者在研究制定延迟退休、社会养老保险全国统筹等政策时需要充分考虑参保职工内部不同群体间的平均预期寿命差别,对低收入参保者予以特别关注。     

The Optimal Allocation Combination for the One-Sided Sequential Screening Procedure Based on the Individual Misclassification Error

In this article, the expected total costs of three kinds of quality cost functions for the one-sided sequential screening procedure based on the individual misclassification error are obtained, where the expected total cost is the sum of the expected cost of inspection, the expected cost of rejection, and the expected cost of quality. The computational formulas for three kinds of expected total costs are derived when k screening variables are allocated into r stages. The optimal allocation combination is determined based on the criterion of minimum expected total cost. At last, we give one example to illustrate the selection of the optimal allocation combination for the sequential screening procedure.     

CUSUM Control Charts for Multivariate Poisson Distribution

A cumulative sum control chart for multivariate Poisson distribution (MP-CUSUM) is proposed. The MP-CUSUM chart is constructed based on log-likelihood ratios with in-control parameters, Θ₀, and shifts to be detected quickly, Θ₁. The average run length (ARL) values are obtained using a Markov Chain-based method. Numerical experiments show that the MP-CUSUM chart is effective in detecting parameter shifts in terms of ARL. The MP-CUSUM chart with smaller Θ₁ is more sensitive than that with greater Θ₁ to smaller shifts, but more insensitive to greater shifts. A comparison shows that the proposed MP-CUSUM chart outperforms an existing MP chart.     

t-Latinized Designs

A variety trial sometimes requires a resolvable block design in which the replicates are set out next to each other. The long blocks running through the replicates are then of interest. A t -latinized design is one in which groups of these t long blocks are binary. In this paper examples of such designs are given. It is shown that the algorithm described by John & Whitaker (1993) can be used to construct designs with high average efficiency factors. Upper bounds on these efficiency factors are also derived.
