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. 相似文献

Probability theory in fuzzy sample spaces 总被引:2,自引:0,他引:2
This paper tries to develop a neat and comprehensive probability theory for sample spaces where the events are fuzzy subsets of The investigations are focussed on the discussion how to equip those sample spaces with suitable -algebras and metrics. In the end we can point out a unified concept of random elements in the sample spaces under consideration which is linked with compatible metrics to express random errors. The result is supported by presenting a strong law of large numbers, a central limit theorem and a Glivenko-Cantelli theorem for these kinds of random elements, formulated simultaneously w.r.t. the selected metrics. As a by-product the line of reasoning, which is followed within the paper, enables us to generalize as well as to bring together already known results and concepts from literature.Acknowledgement. The author would like to thank the participants of the 23rd Linz Seminar on Fuzzy Set Theory for the intensive discussion of the paper. Especially he is indebted to Professors Diamond and Höhle whose remarks have helped to get deeper insights into the subject. Additionally, the author is grateful to one anonymous referee for careful reading and valuable proposals which have led to an improvement of the first draft.This paper was presented at the 23rd Linz Seminar on Fuzzy Set Theory, Linz, Austria, February 5–9, 2002. 相似文献

A social choice rule (SCR) is a collection of social choice correspondences, one for each agenda. An effectivity rule is a collection of effectivity functions, one for each agenda. We prove that every monotonic and superadditive effectivity rule is the effectivity rule of some SCR. A SCR is binary if it is rationalized by an acyclic binary relation. The foregoing result motivates our definition of a binary effectivity rule as the effectivity rule of some binary SCR. A binary SCR is regular if it satisfies unanimity, monotonicity, and independence of infeasible alternatives. A binary effectivity rule is regular if it is the effectivity rule of some regular binary SCR. We characterize completely the family of regular binary effectivity rules. Quite surprisingly, intrinsically defined von Neumann–Morgenstern solutions play an important role in this characterization. 相似文献

德国新历史学派是19世纪最主要的经济思想之一,其主要观点在抨击自由经济主义的同时,也为德意志帝国社会保障体系的建立提供了直接理论基础。而当今德国的医疗保障实践则是政府主导、市场参与的“混合型”医疗保障模式,这充分综合了政府和市场两种资源配置方式的优势。德国新历史学派的主要观点和德国实践经验对我国当前的医疗改革有较好的指导意义。我国医改必须重新对政府与市场在医疗保障改革中进行合理定位、明确边界,建立国家主导、市场参与的“混合型”医疗保障模式。市场化或者国家统管的医疗改革方案都是违背理论规律和历史实践的。 相似文献

This article develops and tests a conceptual model of the transfer process whereby perceived similarity organized around shared
goals facilitates the transfer of knowledge and affect from a parent brand to an extension of that brand. Empirical results,
based on two well-known brands and two hypothetical product extensions for each brand, demonstrate that the availability of
well-formed, goal-derived categories associated with a parent brand establishes an organizing framework for consumers' assessments
of similarity thatfacilitates the transfer of consumer knowledge and attitude from the parent brand to a brand extension in
another product category. This facilitating effect of similarity does not occur in the absence of goal-derived categories.
The results also reveal how marketing communication can be used to facilitate the transfer process by framing similarity in
terms of common goals. Implications are discussed for the organization of consumer knowledge and affect across product categories
and for understanding prior research findings on brand extension.

人民币实际汇率对进出口的影响较名义汇率大,汇率下降可以成功地带动出口,汇率上升也可以减少出口,但对进口影响不大。人民币汇率变动与利用外资之间没有互动关系,甚至呈现异动情况,人民币汇率变动与国内物价水平之间有较高的相关性。 相似文献

在入世的背景下,物流日益得到了全社会和各企业的高度重视,这不仅符合现代经济的发展趋势,也是值得我国大力发展的领域。但是,与此同时,我们也应看到,现代物流产业的发展决不是一件简单的事情,也并非一蹴而就,它是经济发展到一定程度,在政府的宏观调控下以及企业的积极实践和不断努力的结果。因此,在西部物流产业的发展中,政府应当发挥其重要的规划、引导、协调作用,使西部物流管理水平得到极大提高,使西部物流实现现代化。 相似文献
