顾客第一论

“顾客第一”有其特定的内涵,它充分体现社会主义企业的根本目的,因而是企业所有经营观念中的一个根本性观念,也是企业生产经营的一个根本指导思想。企业要实现其双重目的,促进物质文明和精神文明建设的发展,并树立各种现代经营观念,就必须坚持顾客第一。     

碳限额与交易约束下的企业制造/再制造生产决策

目的/意义随着再制造经济效益和环境效益凸显,越来越多的企业进入再制造领域,与原制造商进行竞争或合作。考虑到碳排放约束,企业面临的生产决策更加复杂。设计/方法基于消费者对新产品和再制造产品的异质需求,构建了制造商和再制造商之间的竞争与合作博弈模型,探讨碳税对制造/再制造决策的影响;结合数值仿真,分析了竞争与合作模式下碳税对企业利润及碳排放的影响。结论/发现不同模式下,企业可根据再制造产品碳排放强度选择不同的生产策略;碳税总是会抑制新产品的生产,当再制造产品碳排放强度低于一定数值时,碳税会促进再制造产品的生产;再制造商竞争会挤兑新产品,使制造商利润减少,再制造门槛提高;当碳税不超过一定限度时,合作模式能够实现经济效益和环境效益双赢。     

悲剧的现代体验——徐志摩小说创作论

徐志摩区分出了不同层次种类的情,其中朝向大自然的热情最为显明。其小说呈现了人类遭遇现代后的搏斗的体验,反映了日常生活的残酷性和非人性,意在维护情爱的理想,为感情张目;志在揭示平凡生活中的摩擦,不厌其烦地制造习常和平中的悲剧,展现生活中的压抑和痛苦。

Data-dependent probability matching priors of the second order

In this paper, we consider the preliminary test approach for the estimation of the regression parameter in a multiple regression model under a multicollinearity situation. The preliminary test two-parameter estimators based on the Wald (W), likelihood ratio, and Lagrangian multiplier tests are given, when it is suspected that the regression parameter may be restricted to a subspace and the regression error is distributed with multivariate Student's t distribution. The bias and mean square error of the proposed estimators are derived and compared. The conditions of superiority of the proposed estimators are obtained. Finally, we conclude that the optimum choice of the level of significance becomes the traditional choice by using the Wald test.     

Probability matching priors for two-sided tolerance intervals in balanced one-way and two-way nested random effects models

We consider two-sided Bayesian tolerance intervals, with approximate frequentist validity, for a future observation in balanced one-way and two-way nested random effects models. Probability matching conditions, specific to this problem, are derived in either case via a technique that involves inversion of approximate posterior characteristic functions. In addition to yielding probability matching priors for the present problem, these conditions are useful in evaluating certain other priors that have received attention in the literature.     

More flexible sequential and non-sequential designs in long-term clinical trial

In this paper, we describe decision making procedures as they exist in most clinical trials,review some recently suggested approaches to monitoring and clarify how these methods allow greater flexibility in monitoring and explicit specification of data monitoring methods in the protocol.     

Bayesian prediction bounds for the pareto lifetime model

Suppose that the length of time in years for which a business operates until failure has a Pareto distribution. Let x₁ ≤ x₂ x₃ ≤…≤z_k denote the survival lifetimes of the first k of a random sample of n businesses. Bayesian predictions are to be made on the ordered failure times of t h e remaining (n-k) businesses, using the conditional probability density function. Examples are given to illustrate our results.
