Antecedents of corporate spin-offs in Spain: A resource-based approach   总被引：1，自引：0，他引：1  

Flix Lpez Iturriaga  Natalia Martín Cruz 《Research Policy》2008,37(6-7):1047-1056

We explore the antecedents of corporate spin-offs for a sample of 3462 Spanish firms between 1992 and 2002. Using a resource-based approach, we identify three reasons firms engage in spin-offs: (a) to create complementarities, (b) to appropriate residual rents, and (c) to focus on the core business. Specifically, we find that spin-offs are more common among firms that belong to a group able to create networks and new knowledge that can be exploited through spin-offs. In addition, we find that spin-offs are more frequent in firms that wish to exploit strategic advantages achieved through knowledge investments and in firms that increase efforts to the focus on the parent firm's core competences.  相似文献   

The Puzzle of Museum Educational Practice: A Comment on Rounds and Falk     

Daniel Spock 《Curator: The Museum Journal》2006,49(2):167-180

Abstract Museum practice is in the midst of a fascinating practical and theoretical trajectory. The mandate that museums place education at the center of their public service role has had the effect of framing a new set of questions and—inevitably—problems. If museums have primary value to society as educational institutions, what kind of learning actually happens in them? Jay Rounds and John Falk, writing at the leading edge of this inquiry, explore curiosity, motivation and self‐identity as paramount considerations for the special type of learning museums promote. Their analyses present interesting challenges for the museum practitioner, who may observe that people find the pursuit of curiosity pleasurable and value it more highly than knowledge acquisition. The practitioner may conclude that museums have a calling: They stand for the value of curiosity for its own sake, and for that reason will never wear out their welcome.  相似文献

人文学科的有待与无待   总被引：1，自引：0，他引：1  

丹尼尔·赫威茨  童中平 《华东师范大学学报(哲学社会科学版)》2005,37(6):18-26

在当今全球化的语境中,如何实现人文学术的新发展已引起国际学术界的关注。通过对美国的大学和南非的大学中人文学科现状的比较分析,可以发现人文学科所具有的两种依赖性及其所代表的南北差异,人文学科迫切需要在大学及更广的社会体系内保持高度的紧迫感、批评性思考和道德价值;人文学术在今天特殊的有待状态下,仍然可以实现应有的创造。  相似文献   

Proofs produced by secondary school students learning geometry in a dynamic computer environment     

Ramón Marrades  Ángel Gutiérrez 《Educational Studies in Mathematics》2000,44(1-2):87-125

As a key objective, secondary school mathematics teachers seek to improve the proof skills of students. In this paper we present an analytic framework to describe and analyze students' answers to proof problems. We employ this framework to investigate ways in which dynamic geometry software can be used to improve students' understanding of the nature of mathematical proof and to improve their proof skills. We present the results of two case studies where secondary school students worked with Cabri-Géeomèetre to solve geometry problems structured in a teaching unit. The teaching unit had theaims of: i) Teaching geometric concepts and properties, and ii) helping students to improve their conception of the nature of mathematical proof and to improve their proof skills. By applying the framework defined here, we analyze students' answers to proof problems, observe the types of justifications produced, and verify the usefulness of learning in dynamicgeometry computer environments to improve students' proof skills.  相似文献

Textbook publishing in Kenya under a new policy on school textbook procurement     

Daniel Chebutuk Rotich 《Publishing Research Quarterly》2000,16(2):60-72

This article will address the implications for textbook publishing in Kenya under a new policy on textbook procurement. The new policy was launched in September 1998. The main aim of the policy was to transform a largely government run publishing system by liberalising the textbook market through private sector participation. This would give schools and parents the freedom to choose the books to be used in their schools. With continuing reduction in government textbook expenditure (since 1988), it will remain to be seen whether parents have enough purchasing power to buy books. The intensity of marketing to schools and parents will have to be stepped up by publishers if they are to succeed in the more competitive market.  相似文献
