图书流通数据分析的H类指数遴选及应用——以西北农林科技大学图书馆为例     

净玲娣  王立宏  王芹  李雅 《图书情报工作》2020,64(9):65-72

[目的/意义] 优化藏书采访工作和流通管理，实现对藏书采访、藏书总量和结构等状况适时监测、评估、调控等的标准化管理。[方法/过程] 通过对H类指数中的H指数、A指数和G指数相关性、变异性和适应性分析，遴选适用于图书流通数据分析的A指数，并根据帕累托定律采用A指数对西北农林科技大学图书馆2014-2018年的前20%的图书流通数据分别进行统计分析。[结果/结论] 研究结果表明：平均A指数对中图法一级类目与读者性别、读者专业、读者年级以及图书出版社、图书出版年、单位等数据统计分析具有较理想的表现，能够更全面、准确地遴选核心读者群、核心出版者和核心出版年；同时发现，布拉德福定律不仅能够应用于期刊管理，而且能够应用于藏书管理。本文研究能够为探索H类指数分析高校图书馆藏书流通数据提供参考依据。  相似文献   

Enhancing children's literacy skills: designing the Q‐Tales ecosystem for children's e‐book design and publication          下载免费PDF全文

Bonnie Thompson Long  Tony Hall  Michael Hogan  Nikos Papastamatiou 《Literacy》2018,52(3):171-179

This article describes the conceptualisation and development of a pedagogical framework to support the design of e‐books for children to enhance literacy development. It emerged from research undertaken within the Q‐Tales international consortium project of the EU's Horizon 2020 Programme for Research and Innovation, where the aim was to facilitate key stakeholders to collaborate and participate in the online production and publication of high‐quality, educational e‐books for children. The pedagogical framework described here sought to answer the question “What concepts and principles undergird the effective design of pedagogically impactful e‐books for children?” It is grounded by the theoretical underpinnings of socio‐constructivism, constructionism and skill theory, and how they relate to children's literacy development. A framework describing different narrative forms and component features, key pedagogical activities appropriate for different stages of reading development and design recommendations regarding the integration of multimedia into e‐books are also central to the pedagogical framework. As well as informing the design of the Q‐Tales infrastructure for children's e‐book design and publication, we hope the guidelines and pedagogical activities enumerated here will be widely useful for those designing and developing digital, interactive narratives, particularly e‐books to enhance children's emerging literacy.  相似文献   

Affordances of using Multiple Videoed Events to construct a rich understanding of adult–child book readings     

Maria Nicholas 《International Journal of Research & Method in Education》2018,41(2):125-141

This paper explores the affordances of using video-based research to capture a multiplicity of events, along with multimodal representations when producing data related to adult–child book readings. In doing this we answer two questions: (1) why more than one event is needed when seeking a comprehensive collection of information for the purpose of analysis; and (2) why one mode of data production alone (e.g. audio recordings or note taking) is insufficient to record practice or interviews when richness is of priority. This research used three videoed events to produce data. These included videoing: (1) caregiver–child interactions during four shared book reading sessions, (2) interviews with caregivers immediately following each of the reading sessions and (3) video-stimulated discussions with caregivers within two months of the final shared book reading. In this paper, I contribute to discussions that highlight the affordances of using video-based research as a means of capturing the multimodal elements of an experience, which can contribute to the analysis and interpretation of data. I expand on this, however, to suggest that when coupled with a multiplicity of events, video-based research can be a means of pursuing richness via a method that has been criticized for its narrow subjectivity.  相似文献   

基于Bookmetrix的G20国家图书影响力比较研究     

杨思洛  邢欣  郑梦雪 《现代情报》2019,39(7):143-152

[目的/意义]对比分析G20国家图书影响力的现状，为我国提升图书国际影响力提供借鉴。[方法/过程]选择Springer收录的5个学科（化学、工程、医学、法律、历史）图书为样本，以Bookmetrix为数据源，在讨论指标覆盖率与相关性的基础上，从图书的产出数量、5类指标（下载量、引用量、提及量、读者量及评论量）以及合著关系3个方面展开比较分析。[结果/结论]研究发现：1）在指标覆盖率和相关性方面，整体情况与中、美、德等国家层面的表现类似。体现为图书的下载量覆盖率最高，读者量和引用量相关性值较高且稳定。2）中国的国际图书产出量与德国、美国、英国存在较大差距，但在指标均值、综合排名方面表现良好。3）在G20国家图书合著网络中，人文社科类图书国际合作强度明显低于理工类学科；美国、德国具有较高的科研合作实力与影响力；中国的国际合作具有一定基础，但整体影响力作用并不突出。  相似文献   

Mixed control of uncertain jumping time-delay systems     

Magdi S. Mahmoud  Fouad M. AL-Sunni  Yan Shi   《Journal of The Franklin Institute》2008,345(5):536-552

In this paper, we investigate a class of linear continuous-time systems with Markovian jump parameters. An integral part of the system dynamics is a delayed state with time-varying and bounded delays. The jumping parameters are modeled as a continuous-time, discrete-state Markov process. Employing norm-bounded parametric uncertainties and utilizing the second-method of Lyapunov, we examine the problem of designing a mixed controller which minimizes a quadratic performance measure while satisfying a prescribed -norm bound on the closed-loop system. It is established that sufficient conditions for the existence of the mixed controller and the associated performance upper bound could be cast in the form of linear matrix inequalities.  相似文献

札剌亦儿部显贵"国王"爵位封授与承袭     

谢咏梅 《内蒙古师范大学学报(哲学社会科学版)》2003,32(4)

札剌亦儿部木华黎是最早受封国王位号的功臣。1217年木华黎受封国王讫元终,子孙承袭,世世无绝。但嗣封者往往受蒙、汉礼制的双重影响以及对蒙廷的亲疏等因素的作用。国王最初代朝廷全权经营中原。随着大汗亲历戎行及蒙古重心的南移,尤其中原统治机构的构建,国王的军权、政权渐渐被削弱,日渐偏远。其职责也转为充当畿辅藩屏或充任朝廷"藩大臣"。元中后期,由于驸马及部分著有拥戴之功的异姓功臣频繁封王拜爵而势力日涨,国王在异姓功臣中的地位也日渐暗淡了。  相似文献   

《诗经·陈风·墓门》论考     

闫孟莲 《信阳师范学院学报(哲学社会科学版)》2006,26(6):103-106

《陈风.墓门》是《诗经》中一首篇幅简短却颇有争议的诗。笔者通过对陈国历史史实、社会习俗的考证和对该诗关键章句、字词的分析,又参之以相关文献,对《墓门》进行重新释意,同时,通过考证也推定《墓门》诗当完成于公元前548年—公元前544年之间,为《诗经》所收最晚的一首诗。  相似文献
