Disclosure of information by children in social networking—Not just a case of “you show me yours and I’ll show you mine”

This paper reports the results of a study of MySpace use, by Sydney high school children. It examines the reasons why children disclose information on the website and their understanding of some of the privacy issues involved. The study provides a useful beginning for further work in this area. Regression is used to validate a proposed model of the factors influencing information disclosure and cluster analysis provides an indication of characteristics shared by children who disclose sensitive information, such as name, address and telephone number. It also suggests that children who are taught to value privacy are less likely to disclose sensitive information on-line.     

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.     

Modified breastfeeding attrition prediction tool: prenatal and postpartum tests

In earlier studies, the Breastfeeding Attrition Prediction Tool (BAPT) demonstrated predictive validity in the postpartum period. The purpose of this study was to compare the effectiveness of a modified version of the BAPT when given in the last trimester (BAPT1) and following delivery (BAPT2) in predicting breastfeeding attrition among 117 women who planned to breastfeed for at least 8 weeks. Subjects completed the BAPT during a prenatal breastfeeding class and again at delivery, and they received a phone call at 8 weeks to determine breastfeeding status. In this study, neither of the two administrations of the BAPT was predictive of breastfeeding status at 8 weeks. Findings here may differ because subjects in the current study were all committed enough to attend breastfeeding class and, thus, varied less on commitment than women in earlier studies. Significant associations were found with level of education and having a close relative who breastfed. To assist the perinatal educator in identifying women most at risk for early cessation of breastfeeding, the use of three questions regarding level of education, family support, and breastfeeding preparation is suggested.     

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…     

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.
