开放存取期刊遴选实践研究     

涂志芳  刘兹恒 《图书馆论坛》2018,(1):47-55

建设开放存取期刊集成平台、提供开放存取期刊"一站式"服务、资助作者发表开放存取期刊论文等都需要对期刊进行遴选。文章以DOAJ和GoOA为对象,对开放存取期刊集成平台的期刊遴选进行调研;以杜克大学、麻省理工学院、隆德大学、卡耐基梅隆大学为对象,对开放存取期刊论文APC资助的期刊遴选进行调研,分析总结开放存取期刊遴选的原则及特点,以期为其他主体、其他用途的期刊遴选提供借鉴。  相似文献

生存分析法在学术期刊评价上的应用初探     

李 幸 曾 文 范 畅师兵范  望俊成 《中国科技资源导刊 (中国信息导报)》2018,(1):75-84

期刊评价中文献老化理论视角的研究相对薄弱。本文探究生存分析法在学术期刊评价上的应用,在理论上 克服了因领域差异导致的壁垒,并选取CSTPCD中30家中文物理学科期刊作为样本数据集进行实证研究。通过对论文 被引时序数据进行分析,研究物理学科文献老化规律,并选取样本期刊进行对比分析,以探究期刊评价的新思路。  相似文献   

Two Thousand Students,One Librarian: Balancing Depth and Breadth of Library Instruction for Online Graduate Students     

Lindley Homol 《Journal of Library & Information Services in Distance Learning》2018,12(3-4):250-258

Many librarians struggle with how to balance scalable instructional offerings with more personalized instruction for online students—scale tends to come at the cost of personalization and vice versa. This paper will discuss three methods for connecting with online students that range from one-to-one personalization to widely scalable instruction: individual consultations, scaffolded instructional webinars, and asynchronous video tutorials. The student engagement with each type of instruction will be discussed, with ideas for future directions provided.  相似文献   

Power Struggles,Regulation and Responsibility     

Sian Barber 《Media History》2018,24(1):99-114

This article explores the relationship between the British Board of Film Classification (BBFC) and government during the implementation of the Video Recordings Act (VRA). It considers the public Parliamentary debates about the VRA, and places them alongside private correspondence between the Home Office and the BBFC, and internal BBFC material from the recently catalogued James Ferman papers held at the BFI. As well as exploring the introduction of the VRA, this article also aims to briefly consider its implications for the BBFC, how they set about interpreting and implementing its stringent recommendations and how this impacted upon the organisational working practices of the Board. While the VRA was without doubt one of the most significant pieces of legislation within the history of film regulation in Britain, the time is ripe for its reappraisal and with it a re-evaluation of the role played by the BBFC in securing statutory regulatory powers.  相似文献   

视频组播分层解决方案的研究     

李永琴  董春玲 《潍坊教育学院学报》2006,19(2):19-21,24

组播作为一种节约网络带宽、降低网络负载的有效手段,在视频传输中具有广阔的应用前景。本文针对组播中的会话内公平性问题,深入研究了多速率组播分层解决方案的实现机制,并基于目前的研究现状和进展指出了分层组播现存的有关问题。同时为分析分层解决方案在解决组播会话内公平性问题中的有效性,文中通过网络仿真器NS进行了实验评价。  相似文献   

Segmenting the audience of a cause-related marketing viral campaign     

《International Journal of Information Management》2021

This paper analyses the attitudinal effect of a cause-related marketing campaign which becomes viral through social networks. This attitudinal response is observed in three Internet user segments with different affinity levels: i) strong (familiar with the sponsoring brand and the promoted cause); ii) intermediate (familiar with the brand or the cause); and iii) weak (without previous experiences of either the brand or the social cause). To develop our experiment, 360 Internet surfers agree to participate. Their attitudes were measured before and after the showing of a viral spot in which a pet food brand encourages pet adoption. Our results show that a viral campaign works perfectly for the strong-affinity segment and adequately for the week affinity segment. On the contrary, this viral campaign leaves the intermediate-affinity segment indifferent.  相似文献

我国图书情报领域期刊论文的科学数据引用特征研究     

丁文姚  李健  韩毅 《图书情报工作》2019,63(22):118-128

[目的/意义] 探索期刊论文科学数据引用特征与规律不仅有助于描述学科领域对科学数据的利用情况，还能够揭示学术成果表达中的数据引用模式。[方法/过程] 以我国图书情报领域6种期刊2017年与2018年第一期刊载论文为样本，结合国家标准《信息技术科学数据引用》的引用元素，采用内容分析法从9个维度对样本论文的科学数据引用行为进行数据编码，应用统计学方法描述图书情报领域期刊论文科学数据引用特征并探索不同维度特征间的关联关系。[结果/结论] 图书情报领域期刊论文广泛引用来自国内外的统计整理类科学数据，对期刊论文中个人研究科学数据的引用量较大；科学数据引用标注方式与科学数据类型存在一定对应关系，但多样化的标注方式缺乏统一性；二手引用现象较为突出，二手引用程度与科学数据创建者类型相关。  相似文献
