专业观众展览会参观动机研究——来自东莞的证据

以展览业发达的东莞为研究样地,利用因素分析与聚类研究相结合的综合定量方法,对专业观众的观展动机进行综合评估及分类研究。研究表明,专业观众的非购买动机甚过购买动机,他们观展动机的四个维度因子依次为:搜集信息、建立市场关系、考察奖励、采购行为。本研究还发现专业观众的观展动机分为目标模糊型、信息搜集导向型、目标多维明确型三种类型。     

The econometrics of female labor supply and children

This is a survey of applied econometric research on the effects of children on female labor supply. Reasons for interest in the topic, and a basic model and terminology, are reviewed. Concerns are raised about the possible endogeneity of child status variables, and about the instrumental variables approach for dealing with this problem. Alternative ways of conceptualizing and estimating child status effects are considered, together with selected empirical evidence. Relevant developments from the household demand literature are summarized. Basic issues of model choice are also discussed.     

经济发展、资源功能与中国的配置绩效

经济发展理论高度重视各种资源等劳动对象的开发利用。西方经济学的信仰者由于自身存在的认识论缺陷，难以科学认识劳动对象与经济发展的内在关系，进而也难以科学论述资源在发展理论及其模型中的作用和地位。因此，必须遵循马克思的方法论，从理论为实际的反映入手，建立科学的分析模型，以此指导中国经济发展方式的转变，建立生态与经济相协调的可持续发展的资源及能源支撑体系，调整、优化资源及能源的供给与需求结构。     

对社会工作的现状调查与分析——以绍兴市为例

对绍兴139名社会工作的管理和从业人员进行了调查,发现绍兴市社会工作存在人才数量不够、素质不高、结构不合理,社会管理中介组织发展缓慢以及管理政策不配套等三个方面的主要问题。为加强社会工作,应从加强组织领导、健全各项机制、培育民间组织、加强宣传引导等四个方面入手。     

中国与荷兰曲棍球后备人才培养现状对比分析

曲棍球后备人才是一个国家曲棍球竞技水平的标志。荷兰是曲棍球后备人才发展较好的国家,他之所以长盛不衰,一个重要的因素在于有一个雄厚的群众基础和一个科学并行之有效的后备人才培养体系。目前中国后备人才培养方面与荷兰相比存在着问题和不足,这些对中国曲棍球项目的可持续发展是非常不利的。针对上述状况,本文提出了中国曲棍球管理部门应加强和完善管理体制,建立符合中国具体国情的曲棍球后备人才培养机制。     

广西西江流域工业化发展分析

目前广西西江流域工业化发展处于工业化中前期阶段。西江流域工业化发展有其优势和劣势。充分发挥政府的作用、加快基础设施建设、加快工业园区建设和促进民营工业的发展,是推进西江流域工业化快速发展的战略路径。     

A new random permutation test in ANOVA models

This paper developed an exact method of random permutations when testing both interaction and main effects in the two-way ANOVA model. The method of this paper can be regarded as a much improved model when compared with those of the previous studies such as Still and White (1981) and ter Braak (1992). We further conducted a simulation experiment in order to check the statistical performance of the proposed method. The proposed method works relatively well for small sample sizes compare with the existing methods. This work was supported by Korea Science and Engineering Foundation Grant (R14-2003-002-0100)     

Reconfiguring the Supply Network Using Current Performance Data

Reconfiguration of the supply chain network from time to time is essential for businesses to retain their competitive edge. This paper presents a methodology for reconfiguration of an existing supply chain network. The methodology is characterized by two decision levels. In the first level, the current network performance is evaluated and efficient practices are identified. In the next level, a model that incorporates efficient practices is developed to reconfigure the network. This integrated methodology allows for decision maker (DM) input throughout the process. The methodology has been implemented and tested in the reconfiguration of an outbound petroleum supply chain network for CountryMark Cooperative, Inc. In this case study, Data Envelopment Analysis (DEA) is used to analyze current operations and an integer programming (IP) model that incorporates efficiency metrics is developed for selection of distribution facilities and allocation of resources to the facilities. Use of this methodology can lead to improved operations and reduced operating expenses.     

Search for optimal designs in a three stagenested random model

In this paper we define a class of unbalanced designs, denoted by C_k,s,t, for estimating the components of variance in a k-stage nested random effects linear model. This class contains many of the designs proposed in the literature for nested components of variance models. We focus on the three-state model and discuss the determination of locally optimal designs within this class using a systematic computer search. For large sample sizes we show that approximate optimal designs may be obtained using a limit argument combined with numerical optimization. A comparison of our designs with previously published designs suggests that, in many cases, our designs result in substantial gains in efficiency.
