可辩解型产品伤害危机应对策略对品牌资产的影响研究:调节变量和中介变量的作用

企业创建品牌资产需要多年努力,但毁掉它可能仅需一场危机。在可辩解型产品伤害危机发生后,不同的企业采取了不同的应对策略。这说明,对哪种应对策略能有效保护品牌资产这一问题,企业之间没有共识。为解答上述问题,本文用实验法展开研究,结果表明:(1)对企业自身而言,最优的是辩解策略,其次是攻击策略和缄默策略,最差的是和解策略;(2)外界澄清的说服力更强,会淡化企业应对策略间的差异,更有利于保护品牌资产;(3)在无外界应对、采取辩解策略时,企业声誉会正向调节企业应对策略对品牌资产的影响;(4)在各种自变量影响品牌资产的过程中,心理风险充当了中介作用。以上发现为正确应对可辩解型产品伤害危机、有效保护品牌资产提供了启示。     

Immediate Feedback on Accuracy and Performance: The Effects of Wireless Technology on Food Safety Tracking at a Distribution Center

The effects of wireless ring scanners, which provided immediate auditory and visual feedback, were evaluated to increase the performance and accuracy of order selectors at a meat distribution center. The scanners not only increased performance and accuracy compared to paper pick sheets, but were also instrumental in immediate and accurate data capture and tracking in compliance with the Public Health Security Bioterrorism Preparedness and Response Act (BTA) of 2002. The intervention, which required minimal training, successfully accelerated key operational processes and compliance with food safety mandates. The implications for Organizational Behavior Management practitioners are discussed.

Modifying a central composite design to model the process mean and variance when there are hard-to-change factors

Summary.  An important question within industrial statistics is how to find operating conditions that achieve some goal for the mean of a characteristic of interest while simultaneously minimizing the characteristic's process variance. Often, people refer to this kind of situation as the robust parameter design problem. The robust parameter design literature is rich with ways to create separate models for the mean and variance from this type of experiment. Many times time and/or cost constraints force certain factors of interest to be much more difficult to change than others. An appropriate approach to such an experiment restricts the randomization, which leads to a split-plot structure. The paper modifies the central composite design to allow the estimation of separate models for the characteristic's mean and variances under a split-plot structure. The paper goes on to discuss an appropriate analysis of the experimental results. It illustrates the methodology with an industrial experiment involving a chemical vapour deposition process for the manufacture of silicon wafers. The methodology was used to achieve a silicon layer thickness value of 485 Å while minimizing the process variation.     

正确认识我国当前的贫富差距问题

我国当前存在的贫富差距现象是否会造成两极分化?这是一个很敏感的问题,如何正确认识它?我们应采取何种有效措施调控收入分配差距?笔者认为:收入差距拉大不等于出现了两极分化,适当的收入差距的存在,会促进经济的发展,同时还要注意差距的过分拉大给社会带来的消极影响,因此,要制定相关法律、法规、政策有效调控收入分配差距,加快经济发展,完善政府和社会的扶贫措施,从而实现共同富裕。     

AN APPROACH TO OPTIMIZATION IN RESPONSE SURFACE METHODOLOGY

We consider the optimization of a response surface given by a polynomial model. In this article the problem is stated as a stochastic optimization problem. For the first-order model, the E-Model technique is used to find the maximum and stationary points; the exact distributions are derived under the linearity assumption.

     

An Adaptive Exploration-Exploitation Algorithm for Constructing Metamodels in Random Simulation Using a Novel Sequential Experimental Design

In this article, we propose a novel algorithm for sequential design of metamodels in random simulation, which combines the exploration capability of most one-shot space-filling designs with the exploitation feature of common sequential designs. The algorithm continuously maintains a balance between the exploration and the exploitation search throughout the search process in a sequential and adaptive manner. The numerical results indicate that the proposed approach is superior to one of the existing well-known sequential designs in terms of both the computational efficiency and speed in generating efficient experimental designs.     

On Directional Dependence in a Regression Line

Abstract

In this paper, under the assumption of linear relationship between two variables we provide alternative simple method of proving the existing result connecting correlation coefficient with those of skewness of response and explanatory variables. Further we have given a relationship between correlation coefficient and coefficient of kurtosis of response and explanatory variables assuming the linear relationship between the two variables. Simple alternative way of deriving the formula, which helps in finding the direction dependence in linear regression, is discussed.
