Conflicts between the work boundaries established by union contracts and management's interest in efficient work flows have increased sharply as new technology and new management practices make traditional divisions in the organization of work obsolete. We use concepts from organizational theory to examine these conflicts and an innovative attempt to resolve them by defining union boundaries not on the basis of tasks performed, but rather on the basis of employment; the union contract applies to specific workers instead of job titles. This system provides greater flexibility and autonomy for employees, and the results of an attitude survey suggest that it is strongly preferred by workers who feel constrained by traditional union contracts.  相似文献

玻璃球负载纳米级SO4^2—/TiO2固体超强酸的研究   总被引:1,自引:0,他引:1  
制备了玻璃球负载纳米级SO4^2-/TiO2固体超强酸,对其催化活性、重复使用效果、失活原因及再生方法进行了研究。该催化剂对乙酸和丁醇的酯化反应在重复使用9次后,反应3h乙酸的转化率由初次的99.3%变为84.9%,经再生处理,再重复使用6次反应3h乙酸的转化率由初次的98.0%变为78.3%。催化剂失活原因为活性中心被有机物覆盖以及SO4^2-的流失。催化产物的气相色谱说明该催化剂选择性好,无副产物生成。  相似文献

目前VPN技术在各类网络中的应用大量存在,随着网络技术的发展,IP网络中不仅单独承载普通数据业务,3G语音、视频、数据等业务融合承载,综合应用,对网络的承载能力有了更高的要求。而各类业务在VPN中的大量应用,对于使用VPN对各类业务承载的时延、抖动、丢包率等提出更严格的要求。本文试对目前应用最广泛的MPLS/BGP VPN业务中的DiffServ模型的QoS的典型应用场景进行阐述,探讨对VPN业务的QoS保障。  相似文献

This study examines differences in profit and sales performance between the different Wrigley/Rumelt categories of diversification strategy. Our sample comprised 305 large U. K. manufacturing companies over the period 1972–84. Although diversification strategy explained only a small proportion of inter-firm performance differences, once the influence of other firm and industry variables were taken into account, significant differences did emerge. Our findings conflict with those of earlier U.S. studies. In particular, we find that diversified firms outperformed specialized firms and there was no evidence that related diversification was more successful than unrelated.  相似文献

Even though the buyer-seller interaction/negotiation process is receiving increasing attention from the marketing scholars (Capon & Hulbert, 1976; O'Shaughnessy, 1972; Sheth, 1976; Wilson, 1976; Woodside, Bennett & Sheth, 1977), there is virtually nothing in the literature on the influence of the cross-cultural and cross-national settings in which negotiations take place. Yet, we must reckon with the cross-cultural influences on the buyer-seller interaction/negotiation process simply because a vast number of marketing transactions transcend national and cultural boundaries. In other words, multinational and transnational marketing has emerged as a way of life and transactions between buyers of one country/culture and sellers of another country/culture are commonplace. The purposes of this paper are, therefore, to discuss the cross-cultural influences on the buyer-seller interaction process and to provide a conceptual framework which may become useful for empirical research.  相似文献

Evaluating the impact of California's Coastal Commissions' actions on housing costs provide challenges to economists and political scientists for which they lack both adequate theory and data to reach decisive conclusions. At best evaluation of eight years of Commissions' actions indicate that their actions have saved some scarce coastal resources most in need of protection. However, these achievements created some types of excessive costs and market dislocations which promise to affect adversely housing costs in major populous urban areas. Unfortunately the full range of public and private costs remains undefined and current judgments about Commissions' actions must remain tentative.  相似文献

A major assumption in inventory theory in general and in the area of price changes in particular is that the demand for an item is fixed. It is possible that the reduction in price may result in an increase in demand. In fact this is a reason for the sale offered by many organizations. In this paper we use the familiar net present value approach commonly used in financial decision making to analyze and formulate optimal inventory ordering policies. This approach is more accurate and straight-forward than the average annual cost method that is usually used for comparison of alternative inventory policies.  相似文献

Territoriality is the drive of an individual to stake out, establish, maintain, and defend an area of space for personal use. The “area of space” may be physical or psychological. Industrial buyers and others involved in the buying process, as members of organizations, will act to establish individual territories within the organization and may also act to represent an organization's territorial needs. Because an understanding of the behavior of buyers is important to industrial sales people, and because the concept of territoriality is a mixture of psychological processes, physical behavior, and the space surrounding an individual, a Territoriality Scan System is proposed to assist the salesperson in improving his or her sales communications with industrial buyers. A salesperson can gather important information about an industrial buyer's psychological processes by observing the buyer's physical behavior and surrounding physical space using the Territoriality Scan System. These observational measurements can then be used to enhance the entire sales presentation.  相似文献
