后牙折裂原因与分类初探

收集典型病例，观察年龄、牙位、牙髓状况、充填洞型、咬合等与牙折裂的关系，按斜折、纵折、横折、粉碎折四型对牙折进行分类，研究发现：后牙折裂年龄集中在30～60岁，上下颌第一磨牙折裂率最高．折裂与牙髓状况、充填、咬合有关，各型牙折以Ⅰ类B型和Ⅱ类B型牙折率较高．死髓牙、严重磨耗牙、Ⅱ类洞充填的牙要特别注意防止其发生牙折，不同类型的牙折治疗原则应有针对性。     

Are We There Yet? Calculating Wait Time for Popular Digital Titles

E-books and audiobooks are becoming increasingly popular in the United States. Unfortunately, the supply of digital titles does not meet the demand. Library patrons must frequently wait for weeks to receive popular e-books. We examined the issue of wait time for e-book and audiobook titles using three public library patron accounts to gather data consisting of the average daily number of wait spots for each title, and days until the title was available. Based on our observations, we propose the Waiting Reduction Rate (WRR) formula to determine the average number of wait spots per title as a metric to help determine a better holds-to-copy ratio for electronic materials and reduce patron wait time.

语义分类的学科主题演化分析方法研究——以我国图书情报领域大数据研究为例

[目的/意义] 学科主题演化研究有助于掌握学科发展现状、研究热点、研究前沿和发展趋势等情况,是进行科技创新的基础,是面向科技创新的重要研究方向。[方法/过程] 提出一种语义分类的学科主题演化分析方法：将关键词分为研究问题、研究方法和研究技术3类,构建不同语义分类的共词网络;然后基于Fast Unfolding社区发现算法识别具有语义特征的社区（主题）;利用相似度算法计算相邻子时期主题间的相似度,构建学科主题演化图谱,以分析某学科领域研究问题、研究方法和研究技术的变化,实现深度、细致的学科主题演化分析。[结果/结论] 通过对2012-2015年CNKI数据库收录的我国大数据研究领域相关论文数据的处理分析,证明该方法的准确性和有效性。     

Comics and the Modern Library Catalog: New Rules for Breaking the Rules

Scholarly and curricular uses of comics extend to many disciplines in higher education, resulting in increased demand for institutional access to such materials. Despite nearly twenty years of justification in the literature for inclusion of such materials in libraries, there are not widely adopted conventions or models for engaging in the business of a comics collection. At San Diego State University, this presented an opportunity to pioneer new modes of access, from cataloging and organization to storage and retrieval. This article explores the process of making a collection of floppy comics accessible alongside a theoretical discussion of cataloging shortcomings and opportunities.     

Comparing Digital Apples and Oranges: A Comparative Analysis of e-Books Across Multiple Platforms

This session reported the findings of a comparative analysis of how e-books are represented across multiple platforms. In this session, the presenters shared the results of a study that examined how a sample of academic e-books are represented across different platforms. Topics of analysis included: the inclusion of various metadata, the visual presentation of e-book content, and variations in search results. This presentation also focused on the similarities and differences between e-book representation and what impact these various representations might have on users of academic e-books.     

An Interview with Arlene G. Taylor

In this interview, conducted via email during August 2016, Dr. Arlene G. Taylor discusses her career as a cataloger, professor of cataloging and classification, and her work in professional associations. Topics include her early cataloging and teaching experiences, changes in both cataloging practice and the teaching of cataloging, subject analysis, and “aboutness” as compared with form/genre access, professional experiences outside the United States, and the future of MLIS programs.

以图画为本位的文学--图画书的演变史

中国原创图画书开始走向世界,但中国图画书的历史可能比西方更早。图画书本质上是一种出版现象,在中西方不同文化背景中有不同的呈现方式。中西方图画书同源于儿童读物的插图,随着出版科技的进步和读图时代的到来,从“出版热”逐渐形成“文学热”,从“文字的儿童读物”演化为“图画书的儿童文学”,在新世纪交流融合中发展为儿童文学的典型样式——绘本。中国原创图画书的复兴有其深刻的历史文化背景和深厚的民族文学传统,建设中国特色的图画书评价标准和理论体系应该提上议事日程。
