中国人的姓氏具有姓氏数量相对于总人口的比例严重短缺、各汉字姓氏在人口中的实际分布严重失衡、取名用字高度集中等特点。在中文编目规范控制过程中对中国个人名称标目进行区分尤为重要。中国个人名称标目的区分问题包括对古代个人名称和现代个人名称标目形式的问题;标目附加成分选取标准的控制原则、附加成分类型的划分和属性的分析等。将文献计量学的概念引入规范控制研究领域,会进一步丰富编目规则修订工作的信息来源,有助于拓展规范控制的研究领域。参考文献12。 相似文献

进行了2个实验考察在正常阅读(实验1)与快速阅读条件下(实验2)标题及小标题对高低英语水平不同的大学生说明文阅读理解与信息保持的作用。结果表明：不论是正常阅读还是快速阅读,标题及小标题的呈现对读者说明文阅读理解与信息保持均有显著的促进作用,即阅读水平高者与低者都能从标题及小标题中受益,特别是在正常阅读条件下,提供标题与小标题对阅读水平低者的信息保持的促进作用比对高水平者的促进作用大得多。 相似文献

In the rapidly changing news market, quality newspapers are searching for ways to combine established journalistic practices with attractive presentation of their newsprint. On internet news sites, attention-getting headlines are even more important in obtaining readership. This paper investigates the role of incongruity in selection of headings, and recall, recognition, and appreciation of selected news items. In Experiment 1, headlines were written on three incongruity levels: straightforward, ambiguous (trope), or stylistically deviant (scheme). In Experiment 2, news headlines were accompanied by either consistent or inconsistent photographs. Results of both experiments showed that heading incongruity enhanced information processing of news items. 相似文献

Background: Search filters have been developed in MEDLINE and EMBASE to help overcome the challenges of searching electronic databases for information on adverse effects. However, little evaluation of their effectiveness has been carried out. Objectives: To measure the sensitivity and precision of available adverse effects search filters in MEDLINE and EMBASE. Methods: A case study systematic review of fracture related adverse effects associated with the use of thiazolidinediones was used. Twelve MEDLINE search strategies and three EMBASE search strategies were tested. Results: Nineteen relevant references from MEDLINE and 24 from EMBASE were included in the review. Four search filters in MEDLINE achieved high sensitivity (95 or 100%) with an improved level of precision from searches without any adverse effects filter. High precision in MEDLINE could also be achieved (up to 53%) using search filters that rely on Medical Subject Headings. No search filter in EMBASE achieved high precision (all were under 5%) and the highest sensitivity in EMBASE was 83%. Conclusions: Adverse effects search filters appear to be effective in MEDLINE for achieving either high sensitivity or high precision. Search filters in EMBASE, however, do not appear as effective, particularly in improving precision. 相似文献

AbstractAliens: It is the subject of conspiracy theories and nightmares, the name of a blockbuster science fiction/horror movie franchise, and also how the de facto national library of the United States refers to “persons who are not citizens of the country in which they reside.” In 2016, the Library of Congress announced that it would reconsider the usage of “Aliens” and its related terms in the Library of Congress Subject Headings, following a student-led movement to change the pejorative term “Illegal Aliens.” Yet, three years on, these terms remain in the LCSH. Using the “Illegal Aliens” controversy as a case study, this article explores how the LCSH works, its role in research, and its vulnerabilities to bias, and offers proposals for how librarians can help improve the situation. 相似文献

This paper describes the OCLC/LC Fiction Project from the point of view of a cataloger participating in it. The four types of access to individual works of fiction are discussed-form/genre, character(s), geographical setting, and topical. Issues involved in applying these headings to works (such as genre definitions, the nature of fiction, intertextuality, and the cataloger's subjectivity) are also considered in regard to the Project. 相似文献
