网络界面视觉识别系统设计(WVIS)理论研究报告

本课题组接受中国数字科技馆委托,完成了大型网站“人机界面设计与开发”的理论与实践研究性报告。“人机界面设计与开发”研究涉及到三个问题：①网络控制环境下计算机硬件设备的人性化设计问题;②网络信息资源结构有序整合、内容编码、知识树搭建的设计问题;③网络友好界面的艺术设计问题。该课题研究限制在“人机界面设计与开发”的第三个问题范围,分别从符号编码、光效色彩、图形显示、操作指令、结构模块、空间导航、审美认知七个方面做了全面的实验性研究。该课题研究将涉及到网络技术、计算机科学、人工智能、认知心理、语言符号、艺术设计等许多学科知识,因而,它也是一个交叉和复合的新学科研究项目。我们期望在中国数字科技馆资源建设大平台基础上,通过此研究工作起到抛砖引玉作用,以促进该学科领域的深入研究与运用。     

科研机构向公众开放活动中的问题研究——以中科院为例

科研机构向公众开放是其重要的社会责任和义务,有利于提升我国的科普能力。近年来,中科院利用自身的资源优势开展了“公众科学日”等开放的活动,本文在深入调研的基础上,从政策、组织运行、经费、评价激励等方面入手,对中科院向公众开放过程中存在的问题进行了分析,并尝试提出解决问题的建议。

Using a virtual learning community (VLC) to facilitate a cross-national science research collaboration between secondary school students

This paper reports on how a virtual learning community (VLC), set up on Wikispaces, facilitated cross-national collaboration in high level scientific research involving six teams of four students from two schools, one in Singapore and one in USA. Qualitative case study methods were employed. Data from online postings, reflections and interviews were analysed using the Miles and Huberman (1994) approach to inductive analysis. Findings showed that the students found the VLC useful for their collaboration and the exchanges on the platform positively impacted them in the cognitive, intellectual and interpersonal aspects. Recommendations for future practice and research are made.

The sociology of technology before the turn to technology

This project recommences an underdeveloped conversation between the sociology of technology and classical sociology. There was a vibrant and consistent interest in technology among sociology's founders between Marx and Ogburn and revisiting this tradition is beneficial for contemporary sociological studies of technology. In addition to functioning as exemplars of excellence for the sociology of technology, classical sociology provides distinctive and important considerations and contributions, including: the potential benefits of borrowing technology (Veblen), the ecological influences on technological development and use (Cooley), the impact of technology on science (Mauss), and the rationalization of technology (Weber). Most importantly, classical sociology offers partial though unique frameworks for examining technology in society and vice versa, frameworks that are novel precisely because they are out of sync with recent trends.     

A Note on the Use of Discrete Convolutions

A convolution method is used to solve a tolerance stack-up problem. The input random variables can be of any form. A complete frequency distribution of the possible outcomes is generated in the process of obtaining the desired probability of exceeding the permissible tolerance. (This method has also proved valuable in the actuarial field; for example, in determining the probability that total insurance claims will not exceed a given level.)     

Five Tourniquets and a Ship's Bell: The Special Session at the 1931 Congress

A mythology surrounds the 1931 Second International Congress of the History of Science and Technology. The event is portrayed as a calm and learned gathering where political dispassion and liberal tolerance towards the Soviet delegation were the order of the day. This is, in fact, a myth circulated by some of the participants who wanted to gloss over the conflict that actually characterized the congress. The notion finds its apex in the events surrounding the Special Session that is often positioned as the platform created for the Russians to deliver their papers. This was not the case. A persistent clash occurred between the Soviet delegation and Charles Singer throughout the congress, fuelled by Singer's attempts to generate publicity for the event and a powerful press reaction to the presence of the Soviets. The Congress became a significant focus for politics in Britain and Singer reacted by trying to silence the Soviets. The Special Session, far from being a platform for Marxist history of science, turned into a failed public relations exercise, and ultimately became the stage for the public humiliation of the Soviet delegates.
