Based on evaluations of 1,025 CD-ROM products, this article summarizes trends in (1) growth of commercially available CD-ROM titles; (2) types and subjects of products produced; (3) update options; (4) hardware systems CD-ROMs are designed to run on; (5) prices; and (6) multimedia products. Possible future developments that could revolutionize…

Discusses criteria for evaluating microcomputer database management systems (DBMS) used for storage and retrieval of bibliographic data. Two popular types of microcomputer DBMS--file management systems and relational database management systems--are evaluated with respect to these criteria. (Author/MBR)

Provides an overview of methods for improving the effectiveness of Boolean retrieval systems, including document clustering, relevance feedback, weighted term searching, ranked output, and fuzzy set theory. The discussion of experimental studies with the SMART and SIRE systems focuses on the implementation and results of these methods. (69…

Describes the PADOK-II project in Germany, which was designed to give information on the effects of linguistic algorithms on retrieval in a full-text database, the German Patent Information System (GPI). Relevance assessments are discussed, statistical evaluations are described, and searches are compared for the full-text section versus the…

Describes a project that was designed to test the relative efficacy of index terms and full-text for the retrieval of documents in MEDLINE journals. Precision and relevance of citations retrieved from full-text databases versus bibliographic databases is discussed, and the addition of MEDLINE indexing to enhance full-text medical journals is…

Compares and expands upon two approaches to dealing with fuzzy relational databases. The proposed similarity measure is based on a fuzzy Hausdorff distance and estimates the mismatch between two possibility distributions using a reduction process. The consequences of the reduction process on query evaluation are studied. (Author/EM)

Compares two information retrieval systems, CLARIT and TOPIC, in terms of assigned versus derived and precoordinate versus postcoordinate indexing. Models of information retrieval systems are discussed, and a test of the systems using a demonstration database of full-text articles from the "Wall Street Journal" is described. (Contains 21…

Egalitarian and participation-oriented teaching emphasizes critical discussion and informal relationships between students and professors. The authors argue that the use of egalitarian and some aspects of participation-oriented teaching at business schools differs systematically across countries according to the strength of democratic culture.…

Manually managing student test record data at the college level can be inefficient in terms of both time and accuracy. A computer database program was implemented at a community college in Florida to improve student test record management. The database consisted of the test records of students currently enrolled in College Preparatory English and…

Objective: Developing the scientific underpinnings of social welfare requires effective and efficient methods of retrieving relevant items from the increasing volume of research. Method: We compared seven databases by running the nearest equivalent search on each. The search topic was chosen for relevance to social work practice with older people.…

This report provides state-, regional-, and district-level decisionmakers in the Northeast and Islands Region with a description of the "Compendium of Strategies to Reduce Teacher Turnover in the Northeast and Islands Region," a searchable database of selected profiles of retention strategies implemented in Connecticut, Maine,…

The aim of this paper is to describe vocabulary use during semi-spontaneous oral production among instructed learners of French and Spanish at two different stages in the UK educational system: year 9 (near beginners) and year 13 (approximately low-intermediates). The paper mainly focuses on comparing lexical diversity (range or variety of…

Chapters in this book include: (1) E-Learning Indicators: A Multidimensional Model for Planning Developing and Evaluating E-Learning Software Solutions (Bekim Fetaji and Majlinda Fetaji); (2) Barriers to Effective use of Information Technology in Science Education at Yanbu Kingdom of Saudi Arabia (Abdulkareem Eid S. Alwani and Safeeullah Soomro);…

[Slides] presented at AERA in Denver, CO in April 2010. This study examined the relationship between students' self-reported high school grade point average (HSGPA) from the SAT Questionnaire and their HSGPA provided by the colleges and universities they attend. The purpose of this research was to offer updated information on the relatedness of…

This study evaluates the "Education Resources Information Center" (ERIC), "Library and Information Science Abstracts" (LISA), and "Library Literature" (LL) databases, determining how long the databases take to enter records (indexing delay), how much duplication of effort exists among the three databases (indexing…
