从教与学的良性循环探讨大学英语课堂教学互动

在以学生为主体的课堂上,教与学是一种互动的形式。在英语教学中,教师应当善于且有效地实施互动模式,加强师生间交流,促进教与学的良性循环。     

休闲与物理学创造的双向互动性

休闲是科学诞生的基本条件之一。作为时间形态存在着的休闲（闲暇时间）是物理学创造活动得以进行的基本保证,而作为实践形态而存在的休闲则极大地推动了物理学的突飞猛进,并通过技术的中介,给人类社会带来了高度的物质文明和精神文明,反过来在延长了休闲时间的同时,又丰富了休闲的内容与方式。在当今知识爆炸时代与信息化时代,无论是对任何一门学科的教学而言,学校主管部门特别是具体授课者,都应该力求做到得心应手地给学生＂留下空间＂。因为只要有了空间,学生就不仅能够在积极向上、形式各异、多姿多彩的校园文化这个心灵的驿站中,获得精神的慰藉,从而陶冶了情操、恢复了体能、增强了交际能力;而且还能够充分利用课余的闲暇时间,在开放性、交互性、共享性、协作性和自主性的信息化环境中,积极主动地去猎取适合发展自己个性特长的有关知识,进而使他们的知识结构,能够跟得上新知识、新学科与日俱增的时代步伐。     

Diverse socio-technical aspects of a digital archive of Aboriginal languages

ABSTRACT

A socio-technical approach is taken to explore a digital archive of Australian Indigenous cultural heritage. The Living Archive of Aboriginal Languages is considered in terms of what it is currently doing and what it was intended to do. Two ethnographic stories focusing on user interactions and the outcomes of an online survey serve to evaluate the effectiveness of the Archive from the perspective of different users. This is then juxtaposed with a consideration of the original grant application, outlining what was envisaged for the project. This analysis serves to highlight some of the contingent relations and diverse socio-technical aspects of a specific knowledge infrastructure, as it allows multiple forms of interaction, new connections and generative activities as people discover, access and interact with the content now and into the future.     

安全情报概念的由来、演进趋势及涵义——来自安全科学学理角度的思辨

[目的/意义]安全问题是当前国家、政府、企业、社会、大众及学界广泛关注的一个重要现实问题，而安全情报是保障安全的必用之宝，故安全情报研究具有十分重要的理论与现实意义。[方法/过程]运用文献分析法和思辨法，从安全科学学理角度出发，论证基于安全科学视角解读与界定安全情报概念的必要性、重要性与紧迫性，探讨安全情报概念的由来与演进趋势，并分析安全情报的涵义。[结果/结论]从安全科学学理角度看，从安全信息到安全情报的安全管理新认识是提出安全情报概念的根本动力，安全情报概念的总体演进趋势是从分散到统一。同时，从系统安全学角度看，安全情报是指所有影响系统安全行为的安全信息。     

基于STAR-CCM+的汽车挡风玻璃除霜性能提升的仿真分析与研究

采用计算流体动力学的方法,利用STAR-CCM+软件对某一车型挡风玻璃除霜性能进行数值模拟分析。通过对出风口格栅进行调整,改变了暖风气流与挡风玻璃之间碰撞角的大小与碰撞点的位置,优化了挡风玻璃表面暖风气流的分布,提升了除霜性能,为汽车除霜风道的设计和改善车辆除霜性能提供了参考。     

Libraries and Spatial Literacy: Toward Next-Generation Education

The role of the library is to assist citizens in skills development critical to national interest and empowerment as literacy ambassadors, in general. Specifically, the work by the Federal Geographic Data Committee (1994) indicates that spatial literacy is for every citizen and not just a set of workforce specialists. Hence, the use of maps in decision making and problem solving will become fundamental to all professions, including library professionals. Thus, a spatial literacy awareness and rationale for such as standard job ability is discussed as a future librarian workforce proficiency and knowledge transfer medium.     

数字图书馆信息服务的融合与创新——基于2019年JCDL年会论文的综述

[目的/意义]本文通过对2019年国际数字图书馆联合会议(Joint Conference on Digital Library,JCDL)的录用论文进行整体回顾,梳理了本届年会的最新研究成果与学科发展动态,以助国内图情领域学者更好地了解本届年会成果,把握国际数字图书馆领域研究的前沿热点问题。[研究设计/方法]采用文献综述的方法进行研究。[结论/发现]本届年会更加关注数字图书馆如何通过多源数据的融合、数字人文馆藏资源的利用等实现信息服务深度融合;数字图书馆如何通过海量大数据挖掘与利用、用户行为分析提升其服务水平;如何通过对学术文本资源深入挖掘,实现信息计量学在学术评审、学术评价等方面的创新应用。[创新/价值]本文揭示了国际数字图书馆领域的最新发展态势,展望了未来数字图书馆领域的学术前沿方向。     

A teacher’s journey: a first-person account of how a gay,Cambodian refugee navigated myriad barriers to become educated in the United States

Educational institutions, like most social service organizations, need to recognize intersectionality and complexity and move away from monolithic conceptions of homelessness – if they recognize homelessness at all. This first person account of a gay, Cambodian refugee illustrates the enormous complexity schools face in forming institutional responses for the needs of homeless, highly mobile, and economically displaced children and youth. This article demonstrates an effort to avoid reductionist definitions of homelessness and to include experiential representations of humans living at the margins (under the 5th Avenues of the world, in central parks, in downtown shelters, outside of the ethical and systemic “home” of current ideologies and social orders, under the politics of HIV in Africa, as refugees and as those “othered” by dominant social narratives). The research takes place in the context of the At Home At School program at Washington State University.     

Impacts of social economic status on higher education opportunity and graduate employment in China

Based on a nation-wide survey of higher education graduates, this paper analyzes the impact of family background, using paternal occupation and education as indicators, on their scores in the National College Entrance Examination, the level and type of higher education institutions they attend, their employment after graduation, and the income they receive from their first job. It has been found that there are wide disparities among students with different family backgrounds in both access to higher education and their potential employment in China nowadays. This paper also studies how those influences happen. __________ Translated from Peking University Education Review, 2005 July (3)
