Student Perceptions of Chemistry Laboratory Learning Environments, Student–Teacher Interactions and Attitudes in Secondary School Gifted Education Classes in Singapore

This study investigated the chemistry laboratory classroom environment, teacher–student interactions and student attitudes towards chemistry among 497 gifted and non-gifted secondary-school students in Singapore. The data were collected using the 35-item Chemistry Laboratory Environment Inventory (CLEI), the 48-item Questionnaire on Teacher Interaction (QTI) and the 30-item Questionnaire on Chemistry-Related Attitudes (QOCRA). Results supported the validity and reliability of the CLEI and QTI for this sample. Stream (gifted versus non-gifted) and gender differences were found in actual and preferred chemistry laboratory classroom environments and teacher–student interactions. Some statistically significant associations of modest magnitude were found between students' attitudes towards chemistry and both the laboratory classroom environment and the interpersonal behaviour of chemistry teachers. Suggestions for improving chemistry laboratory classroom environments and the teacher–student interactions for gifted students are provided.     

沿海地区计算机制造产业集群跨区域网络构建研究

经过近20年的发展,沿海地区几大产业集群都具备了相当大的规模。但由于受经济区划及行政区划的限制,各大产业集群之间虽然在地理位置上成带状相连,却缺少足够的协同合作与互动,由此导致了各产业集群间产品结构雷同、恶性竞争愈演愈烈的局面。产业集群跨区域网络的构建,特别是跨区域交易网络和创新网络的建设,则可以有效地解决上述问题,有利于提高我国计算机制造产业协同竞争的能力,实现从产业链低端向高端的升级。

Android arete: Toward a virtue ethic for computational agents

Traditional approaches to computer ethics regard computers as tools, andfocus, therefore, on the ethics of their use. Alternatively, computer ethicsmight instead be understood as a study of the ethics of computationalagents, exploring, for example, the different characteristics and behaviorsthat might benefit such an agent in accomplishing its goals. In this paper,I identify a list of characteristics of computational agents that facilitatetheir pursuit of their end, and claim that these characteristics can beunderstood as virtues within a framework of virtue ethics. This frameworkincludes four broad categories – agentive, social, environmental, and moral– each of which can be understood as a spectrum of virtues rangingbetween two extreme subcategories. Although the use of a virtue frameworkis metaphorical rather than literal, I argue that by providing a frameworkfor identifying and critiquing assumptions about what a `good' computer is,a study of android arete provides focus and direction to the developmentof future computational agents.     

Does gender matter in computer ethics?

Computer ethics is a relatively young discipline,hence it needs time both for reflection and forexploring alternative ethical standpoints in buildingup its own theoretical framework. Feminist ethics isoffered as one such alternative particularly to informissues of equality and power. We argue that feministethics is not narrowly confined to women's issues but is an approach with wider egalitarianapplications. The rise of feminist ethics in relationto feminist theory in general is described and withinthat the work of Gilligan and others on an ethic of care. We argue for the need to connect theory toempirical evidence. Empirical studies of gender andbusiness and computer ethics are reviewed. We noteconcerns with surveying a student audience, the issueof how far questionnaires and interviews can get tothe heart of ethical beliefs and problems ofperforming statistical analyses of quantitative data.Although we recognize them, our own small surveycannot avoid all these problems. Nevertheless byrefining our scenarios we are able to offer analternative reading of a hacking problem in terms ofan ethic of care thereby pointing a way forward forfuture research in computer ethics inspired byfeminist theory.     

CERNET网络发展的竞争优劣势分析

首先介绍了中国教育科研计算机网(CERNET)的发展历程和定位,然后根据国际互联网络发展的相关理论和趋势,从不同的角度出发分析CERNET的优势和劣势,最终得出:CERNET在国家政策、用户群体、硬件建设、科研力量、网站后台硬件设施和数据库等技术的使用方面存在着优势;在CERNET的定位、基础硬件建设、接入方式、对下级用户的支持、网络互联互通、出国带宽、网络资源和地区发展不平衡等方面处于劣势的结论。并根据这一优劣势的分析,提出了相关的意见和建议。
