Sensitivity and precision of adverse effects search filters in MEDLINE and EMBASE: a case study of fractures with thiazolidinediones

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.     

An Empirical Research Study of the Efficacy of Two Plagiarism-Detection Applications

This article describes a study of the two most popular plagiarism-detection software platforms available on today's market—Turnitin (http://www.turnitin.com/static/index.html) and SafeAssign (http://www.safeassign.com/). After a brief discussion of plagiarism's relevance to librarians, the authors examine plagiarism-detection methodology and conduct a review of the current literature regarding plagiarism-detection efficacy. To evaluate detection efficacy for Turnitin and SafeAssign, the authors constructed a brief study in which twenty sample papers containing portions of plagiarized material were submitted to each platform. The results show that Turnitin had the highest overall success at plagiarism detection with an 82.4 percent detection rate. Additionally, both platforms had a combined false-positive detection rate of 16.8 percent. The authors conclude that close review of material suspected of plagiarism is still essential for proper identification.     

Learning Anytime,Anywhere

Abstract

As the wealth of business information on the Internet increases, the development of online tools to assist patrons in effectively utilizing the information will become critical. Because the Internet provides information and delivers it, it offers significant opportunities for teaching interactive research strategies at anytime, day or night, and from anywhere patrons have an Internet connection. This paper discusses the design of a step-by-step, interactive tutorial on researching companies online (http://home.sprintmail.com/～debflanagan/index.html) and provides tips and techniques for developing similar tutorials for the Web.     

Comparison of CINAHL, EMBASE, and MEDLINE databases for the nurse researcher

The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. The three databases were searched for citations on topics selected by three nurse researchers and the results were compared. For the search of nursing care literature on a medical condition, it was helpful to search both CINAHL and MEDLINE. CINAHL provided the majority of relevant articles for the second search, on computers and privacy, but inclusion of MEDLINE and EMBASE enhanced retrieval somewhat. The search on substance abuse in pregnancy, not restricted to nursing literature, retrieved better results when searching both MEDLINE and EMBASE. Due to the nature and distribution of the nursing literature, it is especially important for the searcher to understand and respond to the focus of the researcher.
