Collaborative Approaches to the Management of Geospatial Data Collections in Canadian Academic Libraries: A Historical Case Study

The Ontario Council of University Libraries (OCUL) is a consortium of the twenty-one university libraries in Ontario, Canada. Since 1967, OCUL member institutions have worked together to share costs and workload through collective purchasing and licensing of information resources and more recently through the establishment of a shared digital infrastructure known as Scholars Portal. Under the auspices of OCUL, Ontario's university map librarians formed the OCUL Map Group in 1973 to seek opportunities to communicate and collaborate to improve the collections and services they offer their users. The opportunities provided by collaboration have ensured a greater capacity to manage evolving collections of geospatial data. The group has served as a community of practice, which has provided educational opportunities and facilitated collaborative problem solving through a listserv, conference calls, and face-to-face meetings. This collegial environment has also led to the completion of a number of projects, which have resulted in the creation of new technical infrastructures and strategies for sharing the workload of data management tasks. This paper discusses the role of collaboration in OCUL projects and offers some suggestions for others considering embarking on collaborations of their own.     

基于Cite Space的中国健身气功研究进展与热点分析

目的:揭示我国健身气功研究现状,呈现研究进展与热点,为后续研究提供理论铺垫。方法:采用文献计量法,以2004—2019年中国知网数据库中北大中文核心期刊和中文社会科学引文收录的356篇中国健身气功文献为研究对象,利用Cite Space软件对所采集数据进行图谱绘制与内容分析。结果:我国健身气功核心期刊年发文量呈上升趋势但发文总量较低,研究方法以量化研究为主,研究内容侧重于实验应用研究;研究机构合作少,核心机构主要由高校组成,跨学科合作不明显;研究作者中核心作者形成合作团体,其他作者呈离散分布,核心作者数量少且研究方向多样。研究热点呈现9个聚类,主要聚焦在健身气功的传播发展和历史文化的理论研究,以及健身气功对心血管系统、运动系统、免疫系统、神经系统改善作用的实验研究。研究内容的演变过程由生理改善到心理改善呈现单线式发展,心理健康成为研究前沿。结论:我国健身气功研究现状不容乐观。未来应加强跨学科合作,扩大研究广度;加强学科建设和高学历人才培养,增强研究深度;避免单线研究,注重研究内容的全面发展。     

用概念图解读合作学习

概念图是用于表征和揭示知识结构中的意义联系的图表,它可以帮助我们解读合作学习的本质及其历史沿革.同时,它还能清晰地展示合作学习诸多方法,如STAD(小组成绩分工法)、TGT(小组-游戏-竞赛法)、Jigsaw(切块拼接法)、LT(共学式)及GI(小组调查法)的教学模式,以增加实施的可操作性.     

科学技术可视化

随着科学技术的不断发展,新兴技术大量涌现,技术的发展呈现出学科内纵向深入,学科间交叉融合的新特点与新趋势。因此,如何及时把握新兴技术的动态,寻找发展路径,已成为当前科学研究的热点问题之一,基于科学学理论和传统技术评估与预测研究,总结提出了“科学技术可视化”概念,从“科学技术可视化”研究的必要性出发,综合评述了当前国内外“科学技术可视化”的发展状况,并构建了一套适用于“科学技术可视化”图谱的分类体系与辅助决策框架,为科技决策中“科学技术可视化”方法的应用提供了依据。同时,还总结了当前“科学技术可视化”研究中具有代表意义的经典图谱,并总结出了一套“图法”与“图空间”概念,为如何绘制“科学技术可视化”图谱提供了参考。     

Genetic linkage map ofBrassica campestris L. using AFLP and RAPD markers

A genetic linkage map comprised of 131 loci was constructed with an F₂ population derived from an inter-subspecific cross betweenBrassica campestris L. ssp.chinensis cv. ‘aijiaohuang’ and ssp.rapifera cv. ‘qisihai’. The genetic map included 93 RAPD loci, 36 AFLP loci and 2 morphological loci organized into 10 main linkage groups (LGs) and 2 small groups, covering 1810.9cM with average distance between adjacent markers being approximately 13.8cM. The map is suitable for identification of molecular markers linked to important agronomic traits, QTL analysis, and even for marker-assisted selection in breeding programs of Chinese cabbage and turnip.

1982-2017年国外学校体育研究进展分析——基于知识图谱的可视化分析

摘要：以WOS核心合集数据库1982-2017年收录的6889篇学校体育研究文献为数据源,运用知识图谱分析法、文献资料法对国外学校体育的研究进展进行了分析,旨在探寻国外学校体育的热点研究问题,厘清其发展特征,为我国学校体育研究提供借鉴和参考。研究表明,36年学校体育研究的文献发文量历经缓慢发展（1982—2005年）和高速增长（2006—2017年）2个阶段,美、英领衔的美欧地区处于世界领先,高校是学校体育研究的重要阵地;学校体育研究形成了以体育学和教育学为主,心理学、社会学、生理学、医学等学科为支撑学科的复合型学科群;研究热点集中于体育项目、身体活动、运动成绩、体育锻炼、大纲、课程、动机、感知、认知及适应等10个关键词;学校体育研究的知识基础有4类,包括自我决定理论、成就动机目标视角理论、促进儿童青少年体育活动参与和儿童青少年超重肥胖的研究。

Equipping novice teachers with a learning map to enhance teaching practice

Using tools to support learning design has been proven feasible in improving the integration of technology into the curriculum. However, novice teachers are faced with two major issues, including their limited experience in learning design and limited ability in using new technologies. Learning map is explored and developed in e-Textbooks to serves as a scaffolding for novice teachers during their development into expert teachers. This paper presents a case study in which learning map is integrated into learning design with associated resources in an e-Textbook authoring environment. The participants were instructed to complete a learning design task for an e-Textbook during a one-hour session and then complete a questionnaire afterward. The results indicate that novice teachers value the learning map for learning design in e-Textbooks regardless of their background in ICT teaching and learning design. Novice teachers adopt positive attitudes toward the use of templates because of their numerous benefits. The teachers also suggested that better quality templates should be integrated into the authoring tool to distinguish the advantage of e-Textbook learning design from that of a traditional book and to provide them with additional options.
