氟硅酸泵的国产化实践

硅氟酸极具腐蚀性 ,考虑到经济性 ,2 0 #合金、哈氏合金、蒙乃尔等贵金属很少被选为泵材。由于橡胶、塑料等高分子材料具有很好的抗蚀性和一定的机械性能 ,且价格便宜 ,因此一般选用其作为泵体材料。我们通过分析、比较 ,成功选择国产氟硅酸泵替代国外进口泵 ,实现国产化。     

专业化管理的家族企业——新加坡的华人企业

通过考察大量口迷历史记录、个人访谈、文献研究及有关新加坡经济、社会的评论，研究了亚洲金融危机（以下简称危机）前后新加坡华人企业变化及其发展的持续性，表明危机前，这些大型企业由家族制管理变为专业化管理；危机后，其变化趋势有两种，一种由于面临着西方企业日益激烈的竞争，在政府密切关注下，同时也因缺乏有能力、有管理家族企业意愿的后代，家族制度已松散；另一种由于没有政府的直接管制，在危机后消极的市场形势下，为谋求生存，任用有能力的家族后代充分发挥优势，维持着传统的家族制。本文分别从市场、制度（包括文化和政府）及一些主要大公司的领导者行为分析，推导一个路径清晰、条脉分明的管理变化模式，同时提出进一步的研究方向——专业化管理家族企业的结构及政府的角色。     

How Does a Development Moratorium Affect Development Timing Choices and Land Values?

This paper investigates how a development moratorium affects choices of development timing and land values in a framework where both the value of developed property evolves stochastically and the development costs are fully irreversible. We assume that a regulator initially announces that land is not allowed to be developed during a finite period of time in the future. A developer, thus, must decide whether to develop land before the timing ordinance is imposed, or after it expires. The development moratorium reduces the developer’s option value from waiting and, thus, accelerates development. We also use simulation analysis to demonstrate how the other factors that relate to the demand and supply conditions of the real estate market affect this accelerating effect.     

Managers’ Corporate Entrepreneurial Actions and Job Satisfaction

Through the development and extension of theories and scholars’ subsequent empirical analyses of significant, theoretically grounded research questions, the knowledge about corporate entrepreneurship (CE) and its successful use continues to advance. Moreover, the literature suggests important relationships between the corporate environment, managers’ entrepreneurial behavior and successful implementation of corporate entrepreneurship actions. In an attempt to test some of those relationships, we describe an empirical study of 523 managers that examines the relationships among the antecedents to managers’ entrepreneurial behavior, a decision to implement entrepreneurial actions, and resulting job satisfaction and reinforcement practices.     

Structuring Corporate Headquarters: An Investigation of Franchising

This article focuses on the structuring of the corporate headquarters in a franchise organization. Four essential issues that are related to franchisors organizational structure are discussed—homogeneity and heterogeneity of franchisors structure, company-owned and franchise arrangement, the dynamics between strategy and structure, and performing innovative and administrative functions simultaneously in the headquarters. Propositions are given for each issue. The results of qualitative analysis associated with each issue are discussed.     

University Students’ Attitudes Towards Entrepreneurship: A Two Countries Comparison

There is general agreement that attitudes towards the entrepreneur, entrepreneurial activity, and its social function are determinant factors for university students to decide an entrepreneurial career.This empirical study aims at assessing and comparing the attitudes of university students towards entrepreneurship and enterprise formation in Catalonia and Puerto Rico, using a sample of 837 and 435 students, respectively.Results reveal a positive entrepreneur’s image. Both samples have a favorable perception of desirability of new venture creation, although the perception of feasibility is by far not so positive and only a small percentage has the firm intention to create a new company.     

Taking the “Q” Out of Research: Teaching Research Methodology Courses Without the Divide Between Quantitative and Qualitative Paradigms

The purpose of this paper is to provide evidence that the debate between quantitative and qualitative is divisive and, hence, counterproductive for advancing the social and behavioral science field. We advocate that all graduate students learn to utilize and to appreciate both quantitative and qualitative research methodologies. As such, students will develop into pragmatist researchers who are able to utilize both quantitative and qualitative techniques when conducting research. We contend that the best way to accomplish this is by eliminating quantitative research methodology and qualitative research methodology courses from curricula and replacing these with research methodology courses at different levels that simultaneously teach both quantitative and qualitative techniques within a mixed methodological framework.An earlier version of this article received the 2003 Southwest Educational Research Association (SERA) Outstanding Paper Award.
