特色小镇建设发展路径探究——以安徽合肥为例

作为区域治理的重要载体之一,特色小镇建设亟待探寻适宜发展路径以突出自身特色,实现去“同质化”。作为长三角城市群副中心城市的安徽合肥,特色小镇资源丰富,但存在资源空间发展不均、产业形态缺乏丰富性,特色小镇规划建设模式单一、缺乏可持续性等问题。在顺应供给侧结构性改革、促进产业转型升级的现阶段,需要首先根据相对区位引导小镇的产业定位,通过资源现状的存量、增量细分引导建设规划流程及内容,再根据运营主体和发展阶段的分类引导建设运营模式选择,以明晰不同类型特色小镇的多样化发展路径,发挥示范辐射效应和区域协同作用,实现区域联动。     

Time truncated acceptance sampling plans for generalized exponential distribution

Acceptance sampling plans for generalized exponential distribution when the lifetime experiment is truncated at a pre-determined time are provided in this article. The tables are provided for the minimum sample size required to ensure a certain median life of the experimental unit when the shape parameter is two. The operating characteristic function values of the sampling plans and the associated producer's risks are also presented. It is shown that the tables presented here can be used if instead of median life, other percentile life is chosen as the criterion or if the shape parameter is not two. Examples are provided for illustrative purposes.     

澳大利亚的可再生能源发展与可再生能源证书制度

非营利组织运行机制的转变与社会性企业的公益效率

通过非营利组织运行机制市场化的转向,认为市场化的商业机制使自治机制和志愿机制受到冲击,引起了手段性的财政募捐机制、合作机制、竞争机制、监督机制的改变,标志着组织运行的具体环境从内敛走向开放,组织形式从传统走向现代;但是,从社会募捐到市场募捐,志愿精神与利润追求的矛盾日益突出,非营利组织必然要控制目标置换情况的发生;以“社会性企业”出现的非营利组织旨在协调公益精神与商益利润在市场化运行中的冲突,使之达到一种有效的平衡。

Exact confidence interval estimation for the difference in diagnostic accuracy with three ordinal diagnostic groups

In the cases with three ordinal diagnostic groups, the important measures of diagnostic accuracy are the volume under surface (VUS) and the partial volume under surface (PVUS) which are the extended forms of the area under curve (AUC) and the partial area under curve (PAUC). This article addresses confidence interval estimation of the difference in paired VUS s and the difference in paired PVUS s. To focus especially on studies with small to moderate sample sizes, we propose an approach based on the concepts of generalized inference. A Monte Carlo study demonstrates that the proposed approach generally can provide confidence intervals with reasonable coverage probabilities even at small sample sizes. The proposed approach is compared to a parametric bootstrap approach and a large sample approach through simulation. Finally, the proposed approach is illustrated via an application to a data set of blood test results of anemia patients.     

《大学》中的“忠恕”思想浅探

忠恕是儒家的重要伦理范畴之一,核心含义为＂尽己而推己＂,其关键是一＂推＂字。《大学》中＂忠恕＂思想的表现形态有宏观和微观两种。从宏观上看,《大学》中的＂忠恕＂思想表现为＂修齐治平＂这样一个＂内圣外王＂之道;从微观来看,＂忠恕＂思想则表现为＂絜矩之道＂。两种形态均体现了儒家＂忠恕＂思想尽己而推的推衍实质。

赔付率约束下的中国保险公司效率与全要素生产率研究

运用SBM(slack-based measure)方向性距离函数分别计算了赔付率约束下的2006-2016年中国境内的财产保险公司、人身保险公司的经营无效率值,并对无效率值的来源进行分解。在此基础上运用Luenberger生产率指数计算出全要素生产率及其分解项,对中资、外资保险公司的经营效率、全要素生产率及其分解项进行了对比分析。结果表明:财险业的中资大型公司经营效率最高,人身险业的中资公司经营效率明显高于外资公司;投资收益无效率是造成中小型人身险公司和中小型财产险公司无效率的最主要原因;财险业大型公司的全要素生产率低于中小型公司,而人身险业外资公司的全要素生产率明显高于中资公司。     

A mixed double sampling plan based on Cpk

Abstract

Acceptance sampling plans are quality tools for the manufacturer and the customer. The ultimate result of reduction of nonconforming items will increase the profit of the manufacturer and enhance the satisfaction of the consumer. In this article, a mixed double sampling plan is proposed in which the attribute double sampling inspection is used in the first stage and a variables sampling plan based on the process capability index C_pk is used in the second stage. The optimal parameters are determined so that the producer’s and the consumer’s risks are to be satisfied with minimum average sample number. The optimal parameters of the proposed plan are estimated using different plan settings using two points on the operating characteristic curve approach. In designing the proposed mixed double sampling plan, we consider the symmetric and asymmetric nonconforming cases under variables inspection. The efficiency of the proposed plan is discussed and compared with the existing sampling plans. Tables are constructed for easy selection of the optimal plan parameters and an industrial example is also included for implementation of the proposed plan.
