传感器网络中基于虚拟坐标的节点调度方案

首先,建立了极大相似分布模型;其次,引入节点的虚拟坐标的概念,用来替代节点实际的位置坐标.在此基础上,提出了一种分布式的、与节点位置无关的节点调度方案.方案由一个覆盖算法和一个连通算法组成,方案中的覆盖算法利用虚拟坐标信息进行分组.在不需要节点位置信息的条件下,使各个分组内的传感器节点较为均匀地分布在目标区域.该方案不仅解决了任意分组中的节点充分覆盖目标区域的问题,而且保证了网络的连通.仿真实验表明,该节点调度方案在覆盖率、维持分组连通时额外加入到分组内的节点个数以及网络生存时间等性能上均优于与节点位置无关的节点随机调度协议.

Informatics in teacher education in Japan

Abstract This paper charts the developments in information technology (IT) policies in education in Japan over the past decade with particular emphasis on the impacts on teacher education. Beginning with the work of the National Council on Educational Reform in 1985, the Japanese education system initiated a thorough analysis of the role of information technology in all aspects of education from kindergarten through to high school, vocational education and pre- and in-service teacher education. The various approaches culminated in guidelines and statutory requirements relating to both schools' curricula and teacher training, published in the period 1990–1992. More recently other ministries have contributed to developments including the Ministry for International Trade and Industry which has categorized the different types of information engineers and among these is the new Educational Engineer. The paper reports the processes leading to these developments.     

How anchoring and adjusting influence citizens’ acceptance of video-mediated crime reporting: A narrative approach

This study aims to deepen our understanding of specific processes influencing technology acceptance. To reach this goal, we developed a process model from 36 narrative interviews taken from citizens who had their first experience with crime reporting through video-mediated communication technology. Two major findings emerged. Firstly, we observed that the selective accessibility processes of anchoring and adjusting influence citizens’ acceptance of video-mediated crime reporting. Secondly, we found citizens to evaluate this technology primarily on its affective merits, that is, on its social presence. This latter finding complements the current reliance on cognitive predictors in the technology acceptance literature. The former finding complements the reliance on specific beliefs in current technology acceptance literature, because this study finds that actual acceptance of this virtual technology is influenced by citizens’ reliance on their generally held beliefs; their anchoring. The implications of these findings for the study of technology acceptance research are discussed, in particular for technologies mediating both human- and artificial social actors in related (public) service provision settings.

The TRiTS model: teacher roles in introducing digital technology into a school curriculum

The wide use of digital technology for educational purposes opens up some issues regarding its integration within the school curriculum. Our research aims to contribute to the current discussion about how mobile/portable technology can be integrated into formal education. In this perspective, we consider digital technology and media as a potential integral part of school activity that could effectively support educational achievement. However, the way in which it is applied by teachers in a real context can substantially change its impact on effective achievements. In our research, we extensively investigated the role of the teacher in using digital technology for stimulating and prompting classroom activities in class in-line with the school curriculum. In this paper, we first present a model that illustrates the roles of teachers in transforming digital technology as a resource for developing skills as required in educational curricula. The teacher role in introducing technology at school—TRiTS—model has been conceived by combining relevant literature and findings from a case study that we have been running in a primary school over the last 4 years. We then discuss the influence of the different teacher roles on students (their attitude and level of participation), as emerged from our study.
