Standards for book and serial publishers

Although technical standards that affect the way publishers work have been in existence since 1935, publishers began to participate in the process only in the 1970s. Sandra Paul, who participated in the establishment of both the National Information Standards Organization and the Book and Serials Industry Systems Advisory Committees, reviews the role of publishers in using and developing relevant standards. She also offers some predictions about the standards areas in which publishers are likely to be active in the coming decades, especially those affected by internationalization of the industry and the exploitation of new technology. Sandra K. Paul is president of SKP Associates, past chairperson of the National Information Standards Organization, past chairperson, secretary, and subcommittee chair of BISAC, and treasurer of SISAC.

Fluency with information technology

This article contrasts “computer literacy” with a deeper kind of knowledge and understanding called “fluency with information technology.” Computer literacy generally focuses on skills—the ability to use a few computer applications. But skills become obsolete with new technologies, and so skills with specific applications are thus necessary but not sufficient for individuals to adapt to new information technologies in the future. By contrast, fluency with information technology includes a skills component—but also includes an understanding of the foundational concepts of information technology and the ability to use problem-solving intellectual capabilities in an information technology context.     

邮发代号亟待规范

凡经邮局发行的期刊均编有代号,称"邮发代号".据对2001年经邮局订购的1487种期刊的调查,现行称谓极不统一,竟达60余种,粗略归类如下:1)冠以地方名称,如"鞍山市邮局发行代号"、"北京报刊发行局代号"等.邮发代号是由国家邮政局为便于发行管理,配给每个地区2个相连序号的发行代号,当我们看到某一出版物的邮发代号便知其发行省(市),因此邮发代号前冠以地方名称实无必要.2)冠以"国内",如"国内发行代号"、"国内发行"等."国内"二字意在区别于"国外";但就现状而言,尚未有"国外邮发代号 ",因此,"国内"纯属多余.3)冠以"发行",如"发行代号国内"、"发行代号"等."发行"2字义不清,没区别发行方式(邮局、自办、征订或联合发行),与邮发代号不甚相符.4)称谓"刊号"."刊号"是期刊管理部门为了统一管理和控制期刊的出版而给定的期刊注册登记的刊号.而"邮发代号"是我国邮政局为各邮区发行的期刊编制的代号,两者的性质、作用不同;因此,称"邮发代号"为"刊号"不妥.5)其他混乱现象,如"期刊邮发代号"、"本刊邮发代号"等,都远不如邮发代号简单明了.

Detection As Multi-Topic Tracking

The topic tracking task from TDT is a variant of information filtering tasks that focuses on event-based topics in streams of broadcast news. In this study, we compare tracking to another TDT task, detection, which has the goal of partitioning all arriving news into topics, regardless of whether the topics are of interest to anyone, and even when a new topic appears that had not been previous anticipated. There are clear relationships between the two tasks (under some assumptions, a perfect tracking system could solve the detection problem), but they are evaluated quite differently. We describe the two tasks and discuss their similarities. We show how viewing detection as a form of multi-topic parallel tracking can illuminate the performance tradeoffs of detection over tracking.     

Planning computer literacy evaluations and lasting changes in introductory computer instruction programs

This paper presents four major issues associated with computer literacy: (1) societal effects brought on by the attitudes of tomorrow's worker and today's student; (2) problems associated with computerizing industries in underdeveloped countries; (3) techniques for maintaining worker productivity in computerized industries; and (4) computers and the future of literacy. Current problems are identified, and possible solutions are reported.     

Techniques for Tracking Perpetual Access

Tracking perpetual access entitlements is a challenging task that is too often simply ignored. Here, the presenter makes the case for the importance of systematically tracking perpetual access and outlines the information that is necessary to record. The presenter also draws on the literature and conversations with ten librarians working on the issue to provide a set of techniques for this task. These techniques incorporate several different systems common to academic libraries and include scenarios that illustrate the use in common situations.     

46种委托办中华医学会系列杂志栏目设置分析

为了了解中华医学会系列杂志栏目设置的现状与问题，抽检2000年出版的46种46期中华系列杂志。存在的问题是：导向栏目少，争鸣栏目少，合二为一，含义不清，使用不当，表达不切，烦琐累赘。建议：既要确定相当数量的选用栏目，又要给责任编辑一个选择范围，以便责任编辑根据需要选择确定栏目；从创品牌栏目做起，向创精品刊物迈进。     

遏制优质稿源外流刻不容缓——以计算机科技类中文期刊为例

优质稿源是科技期刊的生命线。本文以中国知网为检索平台,统计了1998—2017年计算机科学技术类中文期刊的发文情况。分析了综合评价总分排名前3位的期刊发文量和第一著作单位分布情况,以及10种中间地位核心期刊的年发文量趋势。在统计的13种样本期刊中有11种期刊2017年度总发文量较近10年间最高年发文量下降幅度超过20%,其中有4种期刊下降幅度甚至超过50%;第一著作单位是中国科学院和985高校的发文数量更是明显减少,在学科综合评价总分排名前三位的期刊中占全年总发文量的比例已经降低至60%以下。统计结果表明:优质稿源外流现象非常严重。同时也反映了中国科技核心技术的外流、中国国家实力和宝藏资源等信息的外泄,必将严重影响我国的国际竞争力,甚至威胁国家安全。期待高层决策者和政策制订者及时调整科技发展政策,建立具有中国特色的科研评价体系,为我国科技独立自主发展、研发核心技术、走自主创新之路提供条件和环境,最终造福社会、造福百姓。     

Tracking User Behavior with Google Analytics Events on an Academic Library Web Site

ABSTRACT

The primary purpose of an academic library Web site is to serve as a portal to library-acquired content. Navigational design of a library Web site affects the user's ability to find and access content. At Albertsons Library, the goal of the navigational design of the Web site is to mimic user behavior on the Web site to help them access information and articles from over 300 different library vendors. Coordinating with different vendors makes tracking the navigational flow of user behavior difficult with the tool Google Analytics. Using the events feature in Google Analytics, the team responsible for Web design was able to track user flow, and was able to quantify how many users were actual “drop-offs” versus those that were clicks into library resources. Decisions made after acquiring these data resulted in a Web site with a 10 percent or less bounce rate, and decreased the number of clicks required for users accessing the library's content.
