虚拟企业供应链及其“魔方”组织结构

虚拟企业关注＂敏捷＂,供应链强调＂精益＂,如何精益地实现敏捷生产与服务则是虚拟企业供应链的研究范畴。首先给出虚拟企业供应链的概念,然后提出虚拟企业供应链＂魔方＂组织结构模式,并对该组织结构的特点和类型进行定性分析。希望通过研究能有助于虚拟企业、供应链的深入研究,丰富虚拟企业供应链的探索。     

工程制图教学中虚拟模型库使用效果分析

工程制图课程传统的教学模式是从二维到三维再到二维,学习起来比较吃力。教学实践表明,借助于三维CAD软件强大的三维实体造型功能和工程图模块,通过对工程形体的实体模型演示,把形体的抽象、静止的内容转换成形象、生动的立体模型图,采用先三维、后二维、再三维的模式进行教学,收到了良好的教学效果。     

补充货币、社区货币及其试运行路径

通过对克鲁格曼、列特尔和党爱民等学者的研究文献解读，有了补充货币及其社区货币中国试运行的四种选择路径：公益互助性的城市社区货币所昭示的时间经济具有旺盛的生命力；在农村流行的道义性“社区货币”中硬塞进一个信用券证无助于扶贫济困；以名目繁多的消费券为主要标志的社会分红试验显示出全民分红逐渐推广的重要迹象；对网络虚拟货币突破货币发行政府垄断之“门”的小小缺口，宜疏不宜堵。

Editorial

Technological change is altering the way educators deliver subject content. The phenomenal growth and widespread acceptance of the Internet has seen the creation of the Virtual Learning Environment (VLE) in higher education. For the ease of integration of VLEs in higher education, software companies have provided products such as WebCT and Blackboard. From a pedagogical perspective, new technologies must be evaluated in an effort to establish whether their introduction has had a beneficial impact on learning outcomes. To this end, this investigation examines the attitudes of undergraduate accounting students in relation to a number of design features and attributes of WebCT (e.g. bulletin boards, on-line assessment and chat room) as a VLE. Responses from 292 on-campus undergraduate students provided data which associates four factors with improved student motivation. This study found that student satisfaction with the use of a VLE is significantly associated with the provision of: lecture notes, bulletin board, on-line assessment and other tools (chat and video summaries). The diagrammatic representation of the variables identified in this study provides a useful reference point for those educators contemplating the implementation of a VLE.     

某型火炮虚拟样机的建立及可信性验证

针对目前火炮在实际使用过程中,由于测试手段的局限性,进行实弹射击危险性较大,不能很好的判断反后坐装置工作是否正常。本文以虚拟样机技术为研究手段对火炮反后坐装置的工作性能进行评估,通过仿真试验结果,检验虚拟样机的可信性。

基于生命周期的虚拟企业知识活动分析及其伙伴选择过程研究

随着新经济的到来,知识越来越成为企业快速响应市场机遇和获取竞争优势的最短缺资源。而企业自身知识资源的有限性使企业越来越多地采用虚拟企业的高级形态——知识联盟型虚拟企业来弥补企业知识资源的不足以快速响应变化的市场需求。首先对知识联盟型虚拟企业的知识缺口类型进行研究和划分,然后分析并描述虚拟企业生命周期各阶段的知识活动;在此基础之上,探讨虚拟企业组建阶段考虑知识要素的伙伴选择过程;最后,针对不同的知识缺口,提出伙伴选择过程的评价指标体系设计中应考虑的知识性因素。     

Virtual Product Placement as a New Approach to Measure Effectiveness of Placements

Product placement is a fast growing multi-billion dollar industry, yet measures of its effectiveness, which influence the critical area of pricing, have been problematic. Past attempts to measure the effect of a placement and, therefore, provide a basis for pricing of placements, have been confounded by the effect on consumers of multiple prior exposures of a brand name in all marketing communications. Virtual product placement offers certain advantages: as a tool to measure the effectiveness of product placements; as assistance with the problem in the lack of audience selectivity in traditional product placement; as a testing of different audiences for brands; and in addressing a gap in the existing academic literature by focusing on the impact of product placement on recall and recognition of new brands.
