论符号消费与意识

有感于当今符号化消费的现实,试图剖析符号消费与消费者消费意识的关系。通过对符号消费含义的探索,以及对超市、笔记本电脑、高档商品橱窗的个案研究,探索符号消费的表现。其次,符号消费的一些幅面效应也不容忽视,并提供了一些案例供研究。     

Computer-Assisted International Negotiation: A Tool for Research and Practice

This article describes a web-based computer-assisted tool for diagnosing progress in international negotiation. Following a discussion of the need for such a tool, we provide the research sources for its development, present the model on which it is based, describe how it works, and present the results of attempts to validate its diagnoses with case materials. Focusing on flexibility in negotiation, the program consists of questions divided into five categories: issues, parties, delegations, situation, and process. The questions track to variables shown in published studies to influence flexibility. Answers to the questions are processed according to algorithms that include weights derived from the results of a statistical meta-analysis of bargaining studies. An example of the question-answer format and computations leading to the diagnoses are provided. A help function that provides advice for resolving impasses is also described. Strong correspondences between diagnoses generated by the program and actual outcomes obtained in a number of cases attest to the validity of the approach. The article concludes with ideas for further development stimulated by the web-based version of the program.

秦皇岛市海岸线侵淤变化规律研究

海岸蚀退和港口淤积是当今世界各国港口城市迫切关注和急待解决的问题；秦皇岛市是我国环渤海经济区的重要港口城市。本文应用遥感手段，首次创新性地借助地理信息系统（ＧＩＳ）的支持，利用计算机图形图像处理与拟合技术对秦皇岛海岸侵淤时空演变进行定量评价；在此基础上，对其变化规律与影响因素进行了分析研究。最后认为：秦皇岛市现代海岸线总体呈蚀退形式；陆源物质入海量减少、海动力作用及沿岸工程建筑等是其海岸蚀退的主要影响因素。     

Computerizing Barriers in Quality Management in Poland

Speed and flexibility in managing the information is of bigger and bigger importance in management at present. Efficient management of a company requires an access to current information which constitutes the key potential of a company, difficult to forge and of a unique character, thanks to which an appropriate managing the information is an important factor of competitive domination. The best way to achieve such an effect is to computerize the management. The application of computer equipment facilitates the information flow and therefore it dispenses managers from mechanical duties and allows them to focus on conceptual work connected with using the gathered information, whereas a tedious effort of its processing is done by a computer system.
