实际选择权决策框架   总被引：2，自引：0，他引：2  

张定杰  鲁伟铭 《阜阳师范学院学报(社会科学版)》2000,(4):12-18

自从Black—Scholes公式发表之后,期权问题成为财务经济学中最热门的研究领域,其中资本预算决策中的实际选择权方法是迄今为止最前沿的研究领域之一。本论文试图总结实际选择权问题在理论和实践上的发展过程,并提出实际选择权的基本定价方法的框架结构。首先讨论几种传统资本预算方法的缺点,再从灵活性措施的价值引入实际选择权的概念。因为灵活性措施提供的投资机会和金融期权都共同拥有一个最核心的特点:权利与义务的不对称性,故此可以把这些投资机会和金融期权做类比,认为灵活性的投资机会是一种实标选择权。接着概述实际选择权理论的发展历程。然后提出了实际选择权资本决策的总体架构,指出管理者真正关心的应当是扩大的、战略性的净现值。最后给出的若干通解对那些具有相似条件的实际选择权定价都是适用的。  相似文献   

Decreasing students’ stress through time management training: an intervention study     

Alexander Häfner  Armin Stock  Verena Oberst 《European Journal of Psychology of Education - EJPE》2015,30(1):81-94

The aim of this study was to examine the effects of a time management training program on perceived control of time and perceived stress in the context of higher education. Twenty-three undergraduate students attended a time management training intervention and reported demands, perceived stress and perceived control of time directly before 2 and 4 weeks after training. We used a “non-equivalent dependent variable design” (Cook and Campbell, Quasi-experimentation: design and analysis for field settings, p. 118, 1979) with perceived stress and perceived control of time as dependent variables, which should be influenced by the training, and demands as control variable, which should not be changed. As expected, perceived stress decreased and perceived control of time increased after training, whereas demands did not change. Therefore, time management training might be beneficial for undergraduate students’ well-being. Nevertheless, more intervention studies in this field are necessary, especially with lager samples, to contribute to more robust results and conclusions.  相似文献   

How geographic maps increase recall of instructional text     

Raymond W. Kulhavy  William A. Stock  William A. Kealy 《Educational technology research and development : ETR & D》1993,41(4):47-62

This article reviews research on how geographic maps influence the recall of associated text. Drawing on literature from cartography and educational, experimental, and cognitive psychology, the authors describe a model of map-text learning based on dual-coding theory and focused on activities that take place during working memory operations. The instructional implications of the model are explored, and recommendations for instructional applications are given.The authors wish to thank Jenine Doran, Kent Rittschof, Michael Verdi, and three anonymous reviewers for providing insightful comments on earlier drafts of this article.  相似文献   

Mechanismen der Elitebildung im deutschen Bildungssystem     

Prof. Dr. Heinz-Hermann Krüger  Werner Helsper  Reinhold Sackmann  Georg Breidenstein  Ulrich Br?ckling  Reinhard Kreckel  Johanna Mierendorff  Manfred Stock 《Zeitschrift für Erziehungswissenschaft》2012,15(2):327-343

The German education system is currently experiencing two contrasting trends: On the one hand, social opening, e.g. through the introduction of a partially-integrated secondary school system, compensatory all-day-schooling. On the other hand, an increasing vertical hierarchy in certain educational phases, e.g. through the explicitly encouraged introduction of private kindergartens and primary schools and the establishment of prime (academic track) Gymnasien and elite universities. In line with these structural changes, next to equality, the principle of excellence is gaining an increasing significance as a justification argument. This contribution will present the situation from an education-policy perspective, discuss theoretical discourses, and the national and international state of research on the topic of elitism and education. It will close with future research challenges.  相似文献

Integrating technology in a field-based teacher training program: The PT3@ASU project   总被引：4，自引：0，他引：4

The Preparing Tomorrow’s Teachers to Use Technology (PT3) initiative has funded various efforts to improve and enhance the technology preparation of preservice teachers. At Arizona State University, these efforts have focused on providing preservice teachers with opportunities to develop, implement, and evaluate their own instructional activities that utilize technology effectively and appropriately in authentic situations, to give them the myriad of tools necessary to integrate technology into teaching and learning activities. This paper focuses on the integration of these efforts into the field-based elementary education program, and discusses our formative evaluation of the field-based technology integration model, through the following questions: What are the preliminary successes of the model with regard to student perceptions, attitudes, and integration of technology into instructional activities? and What components of the model require additions or modifications?  相似文献
