Comparison of three web-scale discovery services for health sciences research

Objective

The purpose of this study was to investigate the relative effectiveness of three web-scale discovery (WSD) tools in answering health sciences search queries.

Methods

Simple keyword searches, based on topics from six health sciences disciplines, were run at multiple real-world implementations of EBSCO Discovery Service (EDS), Ex Libris''s Primo, and ProQuest''s Summon. Each WSD tool was evaluated in its ability to retrieve relevant results and in its coverage of MEDLINE content.

Results

All WSD tools returned between 50%–60% relevant results. Primo returned a higher number of duplicate results than the other 2 WSD products. Summon results were more relevant when search terms were automatically mapped to controlled vocabulary. EDS indexed the largest number of MEDLINE citations, followed closely by Summon. Additionally, keyword searches in all 3 WSD tools retrieved relevant material that was not found with precision (Medical Subject Headings) searches in MEDLINE.

Conclusions

None of the 3 WSD products studied was overwhelmingly more effective in returning relevant results. While difficult to place the figure of 50%–60% relevance in context, it implies a strong likelihood that the average user would be able to find satisfactory sources on the first page of search results using a rudimentary keyword search. The discovery of additional relevant material beyond that retrieved from MEDLINE indicates WSD tools'' value as a supplement to traditional resources for health sciences researchers.     

Inaugural Essay

New to the Journal of Archival Organization, the “Technology matters in archives” column examines how technology affects archives and archivists. This inaugural column explains the nature of the column and sets the stage for topics and issues that it will address. It examines the meaning of the term technology. Further, the column explores the notion of technological dependence-- not just dependence on digital or electronic systems--as a lens in which to examine the archival enterprise in grappling with twenty-first century issues. Concluding with the suggestion that technology can be considered from three categorical points of view: soft (philosophical approaches and practices), medium (codified processes, guidelines and standards) and hard technology (hardware and software).     

Mapping the literature of hospital pharmacy

Objectives

This study describes the literature of hospital pharmacy and identifies the journals most commonly cited by authors in the field, the publication types most frequently cited, the age of citations, and the indexing access to core journals. The study also looks at differing citation practices between journals with a wide audience compared to a national journal with a focus on regional issues and trends in the field.

Method

Cited references from five discipline-specific source journals were collected and analyzed for publication type and age. Two sets were created for comparison. Bradford''s Law of Scattering was applied to both sets to determine the most frequently cited journals.

Results

Three-quarters of all cited items were published within the last 10 years (71%), and journal articles were the most heavily cited publication type (n=65,760, 87%). Citation analysis revealed 26 journal titles in Zone 1, 177 journal titles in Zone 2, and the remaining were scattered across 3,886 titles. Analysis of a national journal revealed Zone 1 comprised 9 titles. Comparison of the 2 sets revealed that Zone 1 titles overlapped, with the exception of 2 titles that were geographically focused in the national title.

Conclusion

Hospital pharmacy literature draws heavily from its own discipline-specific sources but equally from core general and specialty medical journals. Indexing of cited journals is complete in PubMed and EMBASE but lacking in International Pharmaceutical Abstracts. Gray literature is a significant information source in the field.

浅谈高职英语口语教学

高等职业技术教育中英语专业口语课堂教学不同于以往的口语教学课，因为时代的发展，社会对应用型人才的需求，高职学生的口语课应遵循下列规则：“听”领先于“说”；提高学生的口语交际能力即让他们的表述达意并且得体；注重英语的社会化因素；课堂应以学生为中心，把创造性教育融于职业教育中，教学内容要有时代气息。     

高等师范工笔花鸟画教学中的几个问题及对策

目前师范类美术专业的很多学生进校时仅有一点素描和色彩的基础,对民族传统绘画知之甚少,而需要学习的各类文化、专业课程多,在工笔花鸟画课程方面的课时较少。在教学中,学生面对丰富的工笔画形式无法着手学习传统的基础技法、学习基础技法后不知如何结合现当代的美学思想及工笔画发展趋势,拓展思维,培养创作意识。因此指导学生选择临本、熟悉工具材料性能、选择典型题材进行教学、大胆进行新材料、新技法的尝试等,在有限的教学时间内就能提高学生的学习效果。
