Ownership concentration and innovativeness of corporate ventures

Corporate venture investments are an established means for incumbent firms to access radical innovation. Drawing from a behavioural agency framework, we distinguish two mechanisms that govern the relationship between corporate venture investment and radical innovation, the safety net that corporate sponsors provide and control incentives. While the safety net induces a gap between the radical innovation success of corporate ventures (CVs) and ventures without a corporate sponsor, the superior radical innovation success of CVs decreases with the corporate sponsor’s incentives to control the venture. The impact of the safety net and control incentives further depends on the corporate sponsor’s position vis-à-vis her aspiration level.     

XML:图书馆的战略时机

ＸＭＬ（可扩展标示语言）以它用于数据和文件交换的万能格式而迅速地获得各界的青睐。事实上，ＸＭＬ正在成为信息时代的通用语言。目前由于互联网的飞速发展，“图书馆信息”已处于很不利的状况。为什么？尽管图书馆已经开发了联网目录，进行了特定馆藏的电子扫描工作、数字数据的收藏，以及建立了丰富的网页，但是图书馆信息与网络信息仍然保留着“数字分离”状况。图书馆收藏的数据信息的核心是以一体化图书馆系统所有的形式以及以ＭＡＲＣ格式存贮的。无论是图书馆系统形式，还是ＭＡＲＣ格式，它们的使用主要局限于技术服务部和系统图…     

Evaluating instructional software: A simplified model

This article describes the evaluation of a simplified version of the new software evaluation model proposed by Reiser and Dick (1990). This approach to evaluation of instructional software focuses upon the collection of performance data to determine the extent to which students learn the skills the software is designed to teach. In two field evaluations of instructional software packages, it was found that use of the simplified software evaluation model generally produced evaluative conclusions similar to those reached using the original, more complex model. It was also found that student learning data did not support the high ratings assigned by subjective software evaluation services. These findings support the use of the simplified model by teachers and media specialists who have limited time and resources, and stress the need for local on-site evaluation efforts.     

Are the MDGs enough? Donor perspectives and recipient visions of education and poverty reduction in Rwanda

Achieving the millennium development goals (MDGs) forms the central focus of many donor agencies’ policies, resulting in a renewed focus on basic education. This paper explores the different perspectives of donors and the Government of Rwanda (GoR) with regard to education and training. GoR discourse mirrors the international poverty reduction agenda, yet it is looking well beyond this goal. Striking a balance between providing basic education in line with the poverty reduction agenda and providing higher levels of education and training to attain broader socio-economic goals results in an internal struggle between different policy priorities and viewpoints, and an external struggle with donor agencies whose influence over policy processes is considerable. Nevertheless, a closer look at individual donors in Rwanda reveals that their actual activities demonstrate a less than clear focus on the MDGs, begging the question of just how pertinent the MDGs are.     

Making history relevant to students by connecting past,present and future: a framework for research

History teaching usually focuses on understanding the past as an aim in itself. Research shows that many students don’t see the point of this and perceive history as not very useful. Yet history plays a major role in the orientation on present and future. If students fail to see this, the question arises whether this is due to a lack of explicit attention in history classes on the application of knowledge about the past to the present and the future. This article explores two questions: (1) If history is to be more relevant to students, what kind of objectives should play a central role in history teaching? (2) What kinds of teaching strategies align with these objectives in history teaching? The first question is answered by means of historical and educational theory. The second is answered by exploring a number of teaching strategies that have been described in the literature, as well as a small-scale experiment conducted by the authors. This article aims at providing a basis for developing meaningful history curricula as well as for research into educational strategies which can be deployed to teach students how to make connections between past, present and future.
