基于贸易规模和结构的兵团与中亚五国贸易变动研究

运用结构分解分析技术及选取贸易规模和贸易结构两个影响贸易变动的变量,对兵团与中亚五国的贸易变动进行了研究。结果显示,贸易规模对贸易变动的影响较直观,贸易结构是更深一层次影响贸易变动的因素,但两个研究变量的变化对贸易变动的影响均具有不稳定性。最后,在研究结果的基础上提出了两点建议。

中国钢铁行业实行战略性贸易政策的适用性分析

战略性贸易政策是20世纪70年代产生于美国的一种新的贸易政策理论,突破了规模经济和完全竞争的假设,认为政府对贸易的干预有助于提高一国的贸易福利水平。本文通过对战略性贸易政策的前提假设的分析,结合我国钢铁行业发展现状,认为目前应当实行战略性贸易政策以推动我国钢铁行业的发展,并对此提出了相关的政策建议和措施。     

把山水城市从初步设想变为一门建筑科学学问

本标题源于钱学森 1998年 5月致鲍世行信中提的要求 ,既表明探讨需要深入 ,也表明山水城市倡议提出 10年来已开始具备成为一门学问的条件。　　一、2 0世纪城市理念发展变化历程回顾1.百年来 ,西方先后涌现田园城市、广亩城市、阳光城、有机生长城市、卫星城、功能分区、有机综合发展、生态平衡、可持续发展等新的城市理念。检验这一切理念的唯一标准只能是城市发展实践。2 0世纪是世界城市发展空前迅猛的时代。世界城镇人口中总人口比重 ,已由 1880年的 13 .3 % ,提高到 2 0世纪末的 45%以上。而且同期世界总人口猛增近 3倍 ,由 16.5亿增至…     

THE IMPACT OF FEATURE SELECTION: A DATA‐MINING APPLICATION IN DIRECT MARKETING

The capability of identifying customers who are more likely to respond to a product is an important issue in direct marketing. This paper investigates the impact of feature selection on predictive models which predict reordering demand of small and medium‐sized enterprise customers in a large online job‐advertising company. Three well‐known feature subset selection techniques in data mining, namely correlation‐based feature selection (CFS), subset consistency (SC) and symmetrical uncertainty (SU), are applied in this study. The results show that the predictive models using SU outperform those without feature selection and those with the CFS and SC feature subset evaluators. This study has examined and demonstrated the significance of applying the feature‐selection approach to enhance the accuracy of predictive modelling in a direct‐marketing context.

Comparison of Organization Communication Effectiveness on Construction Firms and Manufacturing Firms

基于用先进的制造业改造传统建筑业的现实需求,在对影响组织沟通的核心要素分析的基础上,设计问卷及测量问题,并进行了数据收集及其信度、效度检验,应用数理统计方法对建筑业和制造业企业的组织沟通有效性进行了比较研究.研究结果表明:制造业企业信息交流的准确性、及时性和充分性均明显好于建筑业企业；而制造业企业的信息交换量虽大于建筑业企业,但差异并不显著.该研究有助于建筑业企业借鉴制造业的先进经验,通过组织沟通有效性水平的提升促进与其他联盟企业的合作.     

Antecedents of customer loyalty: An empirical synthesis and reexamination

Despite the importance of customer loyalty, no comprehensive, empirical work has attempted to assess the general findings across academic studies. The study intends to fill that void by conducting a meta-analysis of empirical findings on the predictors of customer loyalty. Although findings of this study support all the hypothesized main effects, they indicate stronger effect size for trust than for other determinants of loyalty. The study also tests the robustness of previous findings across various research and measurement contexts. The analysis of moderating effects reveals several interesting findings. For instance, attitudinal loyalty measures seem to be a plausible surrogate for behavioral loyalty measures. The effects of customer satisfaction and trust on loyalty are less prominent when products are purchased on a regular and relatively short (as opposed to an irregular and relatively long) purchase cycle. Factors that largely relate to product performance (e.g., satisfaction, quality) have a weaker impact on loyalty in B2B than in B2C settings. Some relationships (e.g., the effect of quality on loyalty) become stronger over time. Furthermore, our results detect consistently weaker effects from studies using single-item (relative to multi-item) loyalty measures.
