服务不满意情境下的消费者反应类型测评及高阶因子分析

过去对于消费者不满意的研究主要关注的是服务失误和消费者抱怨.在消费者抱怨的相关研究中,学者们提出了消费者抱怨行为(CCB)、消费者反应预测(CRE)以及消费者抱怨反应(CCR)来解释消费者的抱怨行为,但对于消费者不满意之后的其它反应类型研究较少.本研究基于学者们对抱怨类型的研究以及组织行为理论中雇员反应类型(EVLN)模型的研究,探讨在消费者行为研究中,消费者对于不满意的反应类型.通过探索性因子分析和验证性因子分析,我们确定了五种消费者在不满意情景下可能有的反应类型.我们希望企业能够认识到不同的反应类型,从而提高服务质量和服务补救的有效性.     

亚洲区域经济合作新领域：区域月良务贸易自由化

在对16个亚洲经济体参与的32件区域服务贸易协定进行经验研究的基础上,本文基于与多边服务贸易体系相对照的视角,对亚洲经济体参与区域服务贸易自由化的机制进行分析,并对亚洲经济体在区域贸易协定框架下的服务贸易自由化水平进行量化评估,以期在一定程度上识别区域服务贸易安排在多边服务贸易安排的基础上取得的进展。     

读者·文本·召唤结构——关于大学英语阅读教学的思考

阅读文本自身所存在的大量空白构成了一个动态、开放并蕴含无限可能的话语结构,它召唤读者通过再创造对其进行建构和填充。这一理论对于大学英语阅读教学具有极大的实践意义,只有充分确立和彰显学生的主体性,尊重文本的多元性解读,促进读者与文本的视域融合并创造积极、平等和和谐的师生对话,才能真正使学生在文本意义构建中发挥建设性作用,从而将阅读知识与能力推进到一个新的高度。     

寇谦之天师道改革探微

关于寇谦之本人生平及其改革天师道使其成熟化、官方化的过程与内容,学界已有详尽的记述。但是,对于寇谦之改革的一些细节问题还值得我们进一步思考与分析。辨析寇谦之改革内容的除去三张伪法的具体所指并不是除去所有的三张旧制,努力探清寇谦之努力划清老子与当时盛传的老子替身李弘之间的界限的意义,以求达到对寇谦之的道教改革的全面具体的了解。     

新生代农民工的矛盾性特征及其应对

当前,随着老一代农民工逐渐退出历史舞台,新生代农民工日益成为农民工群体的主体。虽然来源、务工时间和留城意愿等因素使得新生代农民工内部显现出一些差异性,但就整个新生代农民工群体来说,在其身上都或多或少地存在六大矛盾性特征。应对这些矛盾,需政府、社会和新生代农民工自身的共同努力。     

Progressive multi-state models for informatively incomplete longitudinal data

Progressive multi-state models provide a convenient framework for characterizing chronic disease processes where the states represent the degree of damage resulting from the disease. Incomplete data often arise in studies of such processes, and standard methods of analysis can lead to biased parameter estimates when observation of data is response-dependent. This paper describes a joint analysis useful for fitting progressive multi-state models to data arising in longitudinal studies in such settings. Likelihood based methods are described and parameters are shown to be identifiable. An EM algorithm is described for parameter estimation, and variance estimation is carried out using the Louis’ method. Simulation studies demonstrate that the proposed method works well in practice under a variety of settings. An application to data from a smoking prevention study illustrates the utility of the method.     

农民工的城市融入:财政压力—政策响应模型的构建

福利是影响农民工在城市融入程度的重要因素。财政压力—政策响应模型的基本思路是:福利政策效应取决于财政压力、政策响应能力,而政策响应能力主要受筹资能力和政策协调性的影响。对农民工福利政策相关要素进行分析即形成明晰的福利清单。从政府对农民工福利供给的责任看,流入地政府是农民工福利供给的主要承担者,中央政府和流出地政府在农民工福利供给中也要承担必要的财政责任。     

Joint production and subcontracting planning of unreliable multi-facility multi-product production systems

This article addresses the problem of joint optimization of production and subcontracting of unreliable production systems. The production system considered presents a common problem in the pharmaceutical industry. It is composed of multiple production facilities with different capacities, each of which is capable of producing two different classes of medications (brand name and generic). The resort to subcontracting is double: first, it involves the quantity of products received on a regular basis in order to compensate for insufficient production capacity in existing facilities, second, when needed, urgent orders are also launched in order to reduce the risk of shortages caused by breakdowns of manufacturing facilities. Failures, repairs and urgent delivery times may be represented by any probability distributions.The objective is to propose a general control policy for the system under consideration, and to obtain, in the case of two facilities, optimal control parameters that minimize the total incurred cost for a specific level of the customer service provided. Given the complexity of the problem considered, an experimental optimization approach is chosen in order to determine the optimal control parameters. This approach includes experimental design, analysis of variance, response surface methodology and simulation modeling. It allows the accurate representation of the dynamic and stochastic behaviors of the production system and the assessment of optimal control parameters. Other control parameters which represent the subcontracting are introduced and three joint production/subcontracting control policies (general, urgent, regular) are compared to one another. The proposed joint production/regular subcontracting control policy involves a cost decrease of up to 20%, as compared to results obtained by Dror et al. [1], who used a simplified control policy in addition to a heuristic solution approach for a real case study. This policy offers not only cost savings, but is also easier to manage, as compared to that proposed by Dror et al. [1]. Numerical examples and a sensitivity analysis are also performed to illustrate the robustness of the proposed control policy and the solution approach.     

Using Randomized Response to Estimate the Proportion and Truthful Reporting Probability in a Dichotomous Finite Population

In this paper, an alternative randomized response procedure is given that allows us to estimate the population proportion in addition to the probability of providing a truthful answer. It overcomes a difficulty associated with traditional randomized response techniques. Properties of the proposed estimators as well as sample size allocations are studied. In addition, an efficiency comparison is carried out to investigate the performance of the proposed technique.     

A Bayesian Approach for Multiple Response Surface Optimization in the Presence of Noise Variables

An approach for the multiple response robust parameter design problem based on a methodology by Peterson (2000) is presented. The approach is Bayesian, and consists of maximizing the posterior predictive probability that the process satisfies a set of constraints on the responses. In order to find a solution robust to variation in the noise variables, the predictive density is integrated not only with respect to the response variables but also with respect to the assumed distribution of the noise variables. The maximization problem involves repeated Monte Carlo integrations, and two different methods to solve it are evaluated. A Matlab code was written that rapidly finds an optimal (robust) solution in case it exists. Two examples taken from the literature are used to illustrate the proposed method.
