群组AHP排序的最小最大几何距离方法

对群组判断矩阵提出一种新的最小最大几何距离排序方法(MGDM)。鉴于不同专家所给判断矩阵质量上的差异,MGDM对群组判断矩阵进行不同程度的加权处理,并进行群组一致性检验。     

伽马分布的形状参数的一种估计

本文利用服从伽马分布的随机变量 X 与其逆 X~(-1)的协方差只与形状参数有关这一性质,给出伽马分布形状参数的所谓自逆协方差估计,进而构造了相应的无偏估计,并证明了这类估计的大样本性质:强相合性以及渐近正态性。     

The strong uniform convergence of multivariate variable kernel estimates

We show that sup, completely as, where f is a uniformly continuous density on are independent random vectors with common density f, and f_n is the variable kernel estimate Here H_ni is the distance between X_i and its kth nearest neighbour, K is a given density satisfying some regularity conditions, and k is a sequence of integers with the property that log asn     

Recursive procedures for multiple decisions: finite time memory and stepwise maximum likelihood procedure

A version of the multiple decsion problem is studied in which the procedure is based only on the current observation and the previous decision. A necessary and sufficient condition for inconsistency of the stepwise maximum likelihood procedure is shown to be the boundedness of the likelihood ratios. In the case of consistency the (typically slow) rate of convergence to zero of the error probabilities is determined.     

Recursive estimation of the mode of a multivariate density

Let f be an unknown possibly multimodal density on R^d and let X₁, X₂, … be a sequence of independent random vectors with density f. Several recursive estimates of the mode of f are proposed, and sufficient conditions ensuring their weak and strong consistency are established.     

A consistent system of conditional probabilities which is not compatible with any random field

A consistent, Markovian family of conditional densities is constructed which is not compatible with any random field.     

Connected Substitutes and Invertibility of Demand

We consider the invertibility (injectivity) of a nonparametric nonseparable demand system. Invertibility of demand is important in several contexts, including identification of demand, estimation of demand, testing of revealed preference, and economic theory exploiting existence of an inverse demand function or (in an exchange economy) uniqueness of Walrasian equilibrium prices. We introduce the notion of “connected substitutes” and show that this structure is sufficient for invertibility. The connected substitutes conditions require weak substitution between all goods and sufficient strict substitution to necessitate treating them in a single demand system. The connected substitutes conditions have transparent economic interpretation, are easily checked, and are satisfied in many standard models. They need only hold under some transformation of demand and can accommodate many models in which goods are complements. They allow one to show invertibility without strict gross substitutes, functional form restrictions, smoothness assumptions, or strong domain restrictions. When the restriction to weak substitutes is maintained, our sufficient conditions are also “nearly necessary” for even local invertibility.     

利益一致性、供销社推动与农民专业合作社的联合--基于河北省灵寿县青同镇农民专业合作社联合社的案例分析

通过对灵寿县青同镇农民专业合作社联合社的案例分析发现,该联合社是当地各方利益主体追求外部利润的共同诉求下达成利益一致同意的产物。供销社在联合社的组建和经营过程中发挥了重要作用,显示了在合作社发展不成熟时,由公共部门组织参与推动、组建联合社的必要性。联合社成立后,充分协调发挥组织优势,实现了规模经济与范围经济双重经营绩效。     

中英互译中强弱动词翻译策略探讨——以CATTIⅡ级考试题为例

中英文之间的差别决定了翻译应采取的策略,了解中英文不同的行文习惯,能更巧妙地处理词汇乃至句子的翻译。英文喜静不喜动的特点除了体现为英文较多使用名词,还表现为英文能用弱势动词就不用强势动词,而中文则相反。鉴于此,以CATTI（翻译专业资格（水平）考试）Ⅱ级考试题目为例,从强弱动词的角度探讨中英互译,希望为广大英语学习者,特别是准备参加翻译专业资格考试的学生提供可以借鉴的翻译方法。     

全面品牌管理:服务品牌管理的新视角

将传统产品品牌管理理论直接应用于服务品牌化实践的做法一直备受学界质疑,研究适应服务品牌化的相关理论成为学界关注的焦点。通过对国内外服务品牌化的文献研究,总结了服务品牌的特点,分析了服务品牌化面临的挑战,归纳了服务品牌全面管理的主要内容。研究认为,相较于传统产品品牌,服务品牌具有体验属性、关系属性和公司属性等特点;服务品牌化面临品牌一致性和品牌可控性等方面的挑战,而全面品牌管理是克服服务品牌化挑战的有效策略;全面品牌管理涉及整体性的品牌组织、全员性的品牌参与、全程性品牌管理、一致性品牌沟通和全效性品牌考评。研究结果表明,服务品牌管理应该树立品牌导向观,变革原有基于产品品牌的管理体系,从而建立适应服务品牌化的全面品牌管理体系,这是服务品牌化理论发展的新方向,也是服务企业品牌管理实践的新思路。
