Using Targeted Distributed Collections to Enhance Government Depository Collections at a Regional Level: The ASERL Collaborative Federal Depository Program     

《资料收集管理》2012,37(3-4):307-321

The Association of Southeastern Research Libraries is exploring options for collaborative services and collection analysis for federal government publications in order to improve public access to those collections. The Collaborative Federal Depository Program has developed “Centers of Excellence” (COE), representing multiple complete collections of publications for each federal agency. Working together to create a distributed print retention program, southeastern depository libraries agreed to collect, maintain, and provide access to publications for specific government agencies. The authors discuss the development of the COE model and the expected impact of a regionally based distributed print archive for government documents, and provide an implementation case study.  相似文献

教师网络实践共同体研修活动设计模型研究     

杨卉  王陆  张敏霞 《现代远程教育研究》2012,(2):44-49

随着信息技术的发展,教师网络研修由于其时空分离、开放灵活的特征,受到各国教育行政部门和一线教师的青睐。然而目前的教师网络研修存在研修方式单一、参与者少、交流内容浮于表面、持续性差等问题。基于活动理论和现代远程教育理论构建的教师网络实践共同体研修活动设计模型,纵向结构上以规范、统一的教师基本网络研修活动为基本构件,通过活动调用接口,形成多层次的教师网络研修活动流;横向结构上按对活动任务起直接或间接作用的因素进行区分,以完成活动设计过程中的主次问题,最终解决教师网络研修活动设计复杂、重用与共享难、实践性弱等问题。  相似文献   

基于学习共同体的“校-研-教”华文校本协同研究术     

陈之权  黄龙翔 《现代远程教育研究》2012,(6):62-70

新加坡华文教学队伍在教育部的鼓励与推动下,近10年掀起了以改进华文教学为出发点的校本研究风。当前已有的以学者专家为主导和以一线教师为主导的两种研究模式,都对教师专业成长和教学质量持续提升帮助甚微。协同研究主张结合研究者和实践者的经验与专长,共谋专业知识的提升和实践有效的教学形式,为校本研究提供了一个新的研究方向。南洋理工大学下属新加坡华文教研中心参与的两项校本研究案例显示,基于学习共同体的校本协同研究是提高教学质量、促使教师反思、促进教师教育技术专业发展的有效手段。成功的校本研究,要建立学校领导、研究人员和教师三方组成的“校一研一教”学习共同体,以“协同研究”为取向,建立对研究课题目的、方法和策略的研究共识,合理分工,促进与提高“互补性贡献”,抑制或消除“矛盾性期待”,充分发挥三方的经验与专长,促进教师反思与专业成长,实现教学质量的实质性提高。  相似文献   

溴氰菊酯对大鼠小脑皮质组织中HO和ATPase活性的影响     

王爱珠  唐敏贤  林明道  钟秀英 《宜春学院学报》2012,34(8):102-104

目的:研究溴氰菊酯(DM)对SD大鼠小脑皮质组织中血红素加氧酶(HO)的活性和ATPase活性的影响。方法:(1)成年雄性SD大鼠共40只,其中20只用于血红素加氧酶(HO)的活性的测定,另20只用于ATPase活力测定,均随机分为对照组和DM染毒实验组,实验组中大鼠72小时内给溴氰菊酯(1/20LD50)三次,对照组为相同剂量的玉米油,分别检测小脑皮质组织HO活性和ATPase活性。(2)成年雄性SD大鼠30只,同样方法取出小脑皮质,制成切片,随机分为对照组(相同剂量的玉米油)和5个不同浓度的DM染毒试验组(2×10-7mmol/L、2×10-6mmol/L、2×10-5mmol/L、2×10-4mmol/L、2×10-3mmol/L),测定ATPase活性。结果:整体染毒小脑皮层组织HO活性为对照组的240.39%(p﹤0.05),Na+,K+-ATPase活性为对照组的131.47%(p﹤0.05),Ca2+-ATPase活性增加没有统计学意义,Mg2+-ATPase有显著的抑制作用(P<0.05),为对照组的79.91%。体外试验发现只有达到10-3mmol/L数量级的DM对温育小脑皮质切片组织中的Mg2+-ATPase活性才有显著的抑制作用(P<0.05);且无论何种浓度均未发现上述体内染毒时对Na+,K+-ATPase活性的增加作用。结论:DM可增加大鼠小脑皮质的HO活性,体内体外染毒DM对三种ATPase活性的影响并不一致。  相似文献   

On standardization of the Activity Index     

《Journal of Informetrics》2014,8(3):503-507

Relative Specialization Index (RSI) was introduced as a simple transformation of the Activity Index (AI), the aim of this transformation being standardization of AI, and therefore more straightforward interpretation. RSI is believed to have values between −1 and 1, with −1 meaning no activity of the country (institution) in a certain scientific field, and 1 meaning that the country is only active in the given field. While it is obvious from the definition of RSI that it can never be 1, it is less obvious, and essentially unknown, that its upper limit can be quite far from 1, depending on the scientific field. This is a consequence of the fact that AI has different upper limits for different scientific fields. This means that comparisons of RSIs, or AIs, across fields can be misleading. We therefore believe that RSI should not be used at all. We also show how an appropriate standardization of AI can be achieved.  相似文献   

Teachers at the zone of proximal development – Collaboration promoting or hindering the development process     

《Teaching and Teacher Education》2014

This study focuses on collaborative teacher learning during an in-service education course that supports teachers in creating knowledge and practices for teaching. The study investigates what types of activity support or hinder collaborative development within more-or-less successful teacher teams' group discussions. The findings indicate that collaboration that supports collaborative development consists of ideation, further development of ideas and raising questions. Excessive agreement appears to prevent successful collaborative development. The study suggests that in symmetrical peer-to-peer collaboration, equals are able to support creative collaboration by revising and questioning developed constructions and the developmental process itself, through the application of theoretical knowledge.  相似文献

Virtuality,Technology Use,and Engagement Within Organizations     

Matthew S. Weber  Heewon Kim 《Journal of Applied Communication Research》2013,41(4):385-407

Multinational organizations are turning to collaborative technology to enable virtual organizational structures. While collaborative technology provides distributed workers with new affordances to form relationships and share knowledge, collaborative technology also has complex, interwoven implications for virtual organizing. To disentangle these concerns, this study considers four key dimensions of virtuality—spatial dispersion, temporal dispersion, dynamic structure, and functional diversity—in relation to technology use and engagement with peers within an organization. Survey data were collected in a multinational organization that facilitates work through extensive use of collaborative technology. The results of structural equation modeling reveal connections between two dimensions of virtuality, use of collaborative technology and peer engagement in the organization. Findings suggest that understanding interactions in virtual organizations requires a more nuanced approach to virtuality and active management of technology implementation. Moreover, the findings demonstrate that managers need to actively manage the deployment of new collaborative technology by focusing on specific characteristics of work groups.  相似文献
