解决分布式需求的内在冲突

2006年8月,GEN(I网络创新的全球化环境)项目组公布其项目的设计原则。来自普林斯顿大学、麻省理工大学、华盛顿大学等学校的十二位专家编写了这份报告。该报告阐述了GENI的研究范围、用户的需求、需求的内在压力,以及工程设计的原则。报告指出了GENI的价值主张,广泛的部署、多样化可扩展的网络技术集合、对真实用户流量的支持仍是GENI关注的原则和方向。上期已经介绍第一部分——“分布式需求定义GENI的重心”,本期刊出第二部分——“解决分布式需求的内在冲突”。     

‘Question Moments’: A Rolling Programme of Question Opportunities in Classroom Science

This naturalistic study integrates specific ‘question moments’ into lesson plans to increase pupils’ classroom interactions. A range of tools explored students’ ideas by providing students with opportunities to ask and write questions. Their oral and written outcomes provide data on individual and group misunderstandings. Changes to the schedule of lessons were introduced to explore these questions and address disparities. Flexible lesson planning over 14 lessons across a 4-week period of high school chemistry accommodated students’ contributions and increased student participation, promoted inquiring and individualised teaching, with each teaching strategy feeding forward into the next.     

The Effects of Verbal Mediation Training on the Problem‐Solving Skills of Children with Partial Sight and Children without Visual Impairments

Thirty children with partial sight and 30 children with unimpaired sight aged between 8 and 12 years were randomly assigned to either verbal mediation or visual mediation training regimes. Participants were asked to complete four variations of the Tower of Hanoi puzzle and success on the task was judged on the basis of the number of moves and time taken to complete the puzzles. Children with visual impairments had some difficulty in adjusting to the requirements of the problem‐solving tasks. However, on the final and most difficult of the tasks (a four‐disc problem), the children with impaired sight performed very much like participants without visual impairments. The effect of verbal mediation training was superior to that of visual mediation training in the final trials of the four‐disc problem‐solving period for both children with partial sight and children without visual impairments.     

Education Under the New Modernisers: an agenda for centralisation,illiberalism and inequality?

This article surveys changes at the economic, philosophic, social and political levels to argue that a new agenda for educational policy is taking place in the western world, particularly in the UK and the USA. Driven by the needs for a high tech rather than a low wage economy, by perceived breakdown in the social fabric of society (partly as a consequence of previous New Right policies) and with an underpinning argument at the philosophic level which argues for a new orientation to the conception of the nature of moral thinking, this article argues that what is emerging is an approach to education based upon the notions of communitarianism and character education. Whilst such an approach has the potential to re‐invigorate individuals’ sense of responsibility to their communities, as well as provide a greater sense of meaning and direction to policy aims, it is argued in this article that it also has the possibility of centralising decision making, of increasing the likelihood of illiberalism towards minority beliefs and of neglecting present needs of the underprivileged. It concludes by suggesting that whilst many of these ideas originated in the USA, paradoxically they are likely to have their greatest effect in the UK     

Reinventing the marketing machine

The rhythm of publishers’ marketing efforts is dictated by an entirely outmoded historic model of publication of seasonal lists. Publishers should recognize that market conditions that drove this cycle are long gone and adjust to the realities of the 1990s. Properly used, many of today’s technology tools can assist publishers in building and exploiting the “communities of interest” that are the stock-in-trade of every book marketer.

默顿对科学社会学的贡献

这篇文章是关于默顿及其科学社会学工作的回忆与评论.作者自1960年起先后作过默顿的学生、助手和同事,前后达15年之久,可以说对默顿非常熟悉.文中主要讨论了默顿关于清教与科学的博士论文、关于科学规范的论述、以及关于"马太效应"的文章.作者评论道,默顿一方面未能赋予其清教论题以更一般化的陈述,另一方面又未能对经验资料给予足够的关注,从而导致人们怀疑其马太效应理论的正确性.
