价格促销对品牌资产的影响:竞争反应的高地作用

在价格促销对品牌资产的影响方面,学者们并没有形成共识,原因之一是学者们忽视了竞争者的反应行为,本文旨在探讨竞争反应对这种影响关系的调节作用。本文通过2(品牌资产梯队)×8(竞争反应)的实验设计研究表明,对不同品牌资产梯队的品牌,价格促销对品牌资产的影响存在差异;竞争反应对这种影响关系具有调节作用;竞争对手的影响主要来自同梯队品牌,相反梯队品牌的影响不显著。本文对深入了解价格促销对品牌资产的影响具有重要意义。     

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.     

Variance of the difference between two estimated responses

Minimization of the maximum and average variance of the difference between estimated responses are taken as design criteria for univariate polynomial regression models. An optimal design under the first criterion is derived for the second-order model and a class of designs nearly optimal under the second criterion is obtained for the general polynomial models.

高校领导干部必须高度重视讲政治

讲政治是新形势下党中央对高校领导干部提出的新的更高的要求，是端正办学方向的重要前提，是培养合格人才的思想基础，是成为社会主义政治家、教育家的先决条件。当前，高校领导干部在讲政治方面还存在着理想信念不是很坚定、贯彻党的基本路线不够自觉、办学方向时有摇摆、不能很好处理“政治”与“业务”的关系等问题，因此，必须加强理论学习，深入贯彻党的教育方针，深化教育改革，加强思想政治工作，维护安定团结的大好形势，不断加强班子自身建设。     

Missed opportunity: The NTER and sustainable development outcomes for Aboriginal people in the Northern Territory

This article questions why the Labor Government has failed to fundamentally change the Northern Territory Emergency Response (NTER) which it inherited from the Howard government, in the face of evidence which suggests that it is a development intervention unlikely to bring about sustained change. There are two major problems which this article highlights: the coercive and denigrating approach of the NTER, and its failure to address the need for Indigenous governance to drive lasting Indigenous development. Drawing on global research about the reduction of poverty and evidence about the social and economic development of native nations in other settler states, the article suggests that the NTER has been a missed opportunity for Indigenous development. Better policies would have been to address the barriers which Indigenous people identify as blocking their initiatives for development, and to support the essential work of building effective and legitimate community governance to drive development.     

Fifth order rotability

In this paper, conditions for a set of points to form a rotatable design of order five in three dimensions have been worked out. These conditions form a basis for obtaining a set of rotatable designs of order five. An attempt has been made to generalise these results with partial success.     

大学毕业生就业满意度及政府应对措施

解决大学毕业生的就业，政府应在宏观上迅速提升我国产业价值链在国际中的地位，并在国内努力转变生产方式，创造出更多具有高智能、高技能、高专业技术知识的岗位。大学生除基本能力外．还需培养快捷的角色转换能力，客观的信息挖掘和整理利用能力，健康的求职心理适应能力。因此，大学生要增强对就业的自信，具有敢于竞争的勇气；政府应建立就业指导机构，设置经过国家考核合格的职业就业指导师并规范化运作。
