Discusses advantages and limitations of database software in meeting the educational objectives of history instruction; reviews five currently available computer programs (FACTFILE, QUEST, QUARRY BANK 1851, Census Analysis, and Beta Base); highlights major considerations that arise in designing such programs; and describes their classroom use.…

Describes characteristics of hypertext, how it is currently being used, and discusses possible uses of hypertext in conjunction with online databases. An online medical textbook developed by BRS and Columbia Presbyterian Medical Center is described, links between databases are discussed, and future systems are suggested. (10 references) (LRW)

Provides a direct instruction strategy for teaching skills and concepts required for database use. Creates an interactive environment which motivates, provides a model, imparts information, allows active student participation, gives knowledge of results, and presents guidance. (LS)

Describes current features of the Research Libraries Information Network and ongoing research to enhance the system. Features discussed include access to the central bibliographic database, authority control, nonroman character set support, special databases for search only use, thesauri, videodisk interfaces, and file clustering. (CLB)

Proposes a new learning algorithm to improve the retrieval effectiveness of the search system used in the hypertext environment using an extended Boolean model with links to improve the ranking of retrieved items. Highlights include the basic retrieval scheme, the learning scheme, and a review of basic probabilistic retrieval models. (Contains 32…

Describes a prototype reference collection management system that uses a relational database management program to automate traditional library processes such as library inventory and shelf-reading. Examines reference collection management criteria and system considerations, and reviews the database's characteristics and its benefits to libraries.…

Addresses foundations of designing a bibliographic database for casual end-users, including the representation of knowledge, hierarchical schemata, cognitive processing of search problems, basic level categories of knowledge, and Boolean strategy in online searching. A hierarchical-based query model, data-item model, and idealized data model for…

Discusses natural language retrieval systems, focusing on West Publishing Company's WIN (Westlaw Is Natural) system used with its case law database. Information retrieval models, the advantages and disadvantages of natural language retrieval, and the use of the approach by Congressional Quarterly's Washington Alert, Personal Librarian, and other…

Outlines the current legal structure of the European geographic information system (GIS) database industry, particularly in the area of copyright protection; critiques the impending Commission of the European Communities directive; and emphasizes the need for global consensus on the legal structure's ability to protect and regulate the flow of…

This report, the second annual Database Marketplace survey, analyzes information gathered from 29 companies that distribute and produce information available through online, Web, or CD-ROM systems. In addition to data, topics include company mergers, takeovers, sales, accomplishments, and future plans. (Author/LRW)

Automated persuasion is the Holy Grail of quantitatively biased data base designers. However, data base histories are, at best, probabilistic estimates of customer behavior and do not make use of more sophisticated qualitative motivational profiling tools. While usually absent from web designer thinking, qualitative motivational profiling can be…

Edutella is an RDF-based E-Learning P2P network that is aimed to accommodate heterogeneous learning resource metadata repositories in a P2P manner and further facilitate the exchange of metadata between these repositories based on RDF. Whereas Edutella provides RDF metadata repositories with a quite natural integration approach, XML metadata…

The Data Quality Campaign is a national, collaborative effort to encourage and support state policymakers to improve the collection, availability and use of high-quality education data and to implement state longitudinal data systems to improve student achievement. The campaign aims to provide tools and resources that will assist state development…

Replicating a previous study (M. Barkham et al., 2006), the authors examined rates of improvement in psychotherapy in United Kingdom primary care settings as a function of the number of sessions attended. Included in the study were adult clients who returned valid assessments at the beginning and the end of their treatment, had planned endings,…

Fikkert (1994) analyzed a large corpus of Dutch children's early language production, and found that they often add targetless syllables to their words in order to create bisyllabic feet. In this note we point out a methodological problem with that analysis: in an important number of cases, epenthetic vowels occur at places where grammatical…
