建筑工程安全事故机会损失的确定及计算

安全事故每年都给国家、社会、企业和事故伤害人带来巨大的损失,但由于事故损失的复杂性,很难准确统计.文章为了准确统计事故损失,研究了现有的建筑工程事故损失统计体系,提出将建筑工程安全事故间接损失中机会损失纳入到建筑工程事故损失统计体系中来;定义了建筑工程事故机会损失的概念,提出了建筑工程安全事故机会损失可以细分为建筑工程事故机会损失间接经济损失和间接非经济损失两部分,并分别给出了计算方法,使建筑工程安全事故损失的确定更加全面清晰.

A context-based service matching approach towards functional reliability for industrial systems

ABSTRACT

As service-oriented computing is commonly used in industrial systems to deal with the continually changing business environment, matching processes with existing services becomes one of the most important phases in constructing, integrating and optimizing information systems. The precision of semantic service matching becomes a critical factor in ensuring the correctness of functionalities in system processes. However, the dependability of semantic service matching cannot be warranted in complex contexts. To improve semantic service matching for industrial systems, a context-based semantic service matching approach named ‘Process-Based service MatchMaker’(PBMM) is proposed in this paper. It selects the suitable services for the process from candidate services through taking the dependencies of related services process into consideration.     

Firm Density and Industry R & D Intensity: Theory and Evidence

By deriving a formal model of industry R & D that identifies factors influencing industry R & D intensity, this paper first suggests firm density, defined as the inverse of average firm sales or simply the number of firms divided by industry sales, as a measure of market structure that is appropriate in explaining industry R & D intensity. The model shows that the cost structure of R & D, consumer preference over quality and price, the appropriability of R & D, firm density, and the average level of firm R & D intensity jointly determine industry R & D intensity. In particular, firm density has a positive relationship with industry R & D intensity, implying that firms in higher firm-density industries feel fiercer competitive pressure and thus engage more intensively in R & D. An empirical analysis of panel data on industry R & D activities of Korean manufacturing industries during the period 1991–1996 provides supportive evidence for the predictions of the model including the positive relationship between firm density and industry R & D intensity. The theoretical model and the empirical results are also consistent with the recent survey of U.S. corporate R & D activities by the U.S. Department of Commerce and the National Science Foundation (1999).     

Discovery,invention and serendipity

This paper attempts to relate serendipity, the natural ability to make interesting or valuable discoveries by accident （Longman Discovery of Contemporary English） with notable discoveries and inventions. It connotes the profound ability of finding out valuable things different from those who have been exploring by spending a lot of time or for years. The author will illustrate as many cases as possible within a given time constraint, so that surrounding environments and situations may be clarified, and such discoveries and inventions may be plausibly accomplished by accident or with rich reasons. These illustrations include historical as well as more recent cases. One of the cases is beyond the scope of our environment on the earth with preconceived notion, while other cases have given great impacts to our politics and also military intelligence. It should be noted that business and technological intelligence are deeply connected with discoveries, inventions and serendipity. In concluding remarks, the essence of serendipity will be summarized and how to side with the serendipity at the most important moment will be examined by viewing time series endeavors of the inventors and those who have devoted much time to discoveries.     

基于社会网络的创业机会、动机与创业精神的关系研究

已有的创业精神的研究多基于西方的经济背景和实践。中国社会的历史文化和转轨时期的经济制度等都反映了中国创业精神发展的特殊性。其于制度理论,提出了创业机会、动机与创业精神之间的关系,并结合中国的创业实践认为,社会网络在创业机会、动机与创业精神的关系中起中介作用。     

金融危机对湖北省经济发展的影响探析

在全球金融危机对我国经济发展影响逐步加大的同时,我国中西部地区的发展也受到了或多或少的影响。湖北省作为中部重省,对于金融危机带来的影响是不可忽视的。本文从湖北省受到的影响出发,分析了湖北省在金融危机下面临的挑战,同时也看到了其发展存在的机遇,最后根据湖北省的发展现状从四个角度提出了应对金融危机的措施。     

基于R&D指标的先导性战略新兴产业发现研究

在识别和选择先导性战略新兴产业的过程中,按照其未知、待发掘的特点,透过知识发现的视角,采用关联规则方法,根据R&D经费投入强度指标与专利授权量指标之间的强关联规则关系,建立先导性战略新兴产业数据挖掘关联规则识别模型。以中国长三角地区为实证分析对象,在对该地区的战略新兴产业进行识别时,得出5条符合约束条件的强关联规则,其对应的战略新兴产业的产业顺序分别为高端装备制造、生物医药、新材料、新一代信息技术及新能源等5个产业。
