The first of three articles reports the effectiveness of a feature-matching approach to computer retrieval of graphic information. The second discusses the use of multivariate techniques to measure perceived complexity of database searching by users. The third explores the limitations of user consultation in database design. (Author/CLB)

This interview with Bertrum MacDonald discusses the decisions that determined the character of a national bibliography on science and technology in Canadian history. Topics discussed include the scope of the project; classification and indexing decisions; the database management system used; unexpected problems; and predicted usage of the…

Describes the nature of computerized data bases. Provides an activity using a data base and designing a data base. (YP)

Ways to use data base software to develop conceptual understanding are presented. Discussed are the concepts of a data base, setting up the data, and an assessment of learning with examples. Six references and four journal resources are listed. (YP)

Describes the design and functions of a technical library database maintained on a mainframe computer and supported by the SPIRES database management system. The topics covered include record structures, vocabulary control, input procedures, searching features, time considerations, and cost effectiveness. (three references) (CLB)

Reflects on the thought and process involved in the development of a series of computer simulations used to help teach a two-semester U.S. history course. Lists common elements in the simulations, describes the simulations, and responds to criticisms. Discusses student reaction to the use of computer simulations in a history course. (LS)

This article presents a model approach for management of child sexual abuse data for centers that provide medical evaluations of suspected sexual abuse victims. Information and guidelines for developing a computer database and for efficient entry of the data by clinical personnel are outlined. (Author/JDD)

Presents the objective and methodology chosen for the construction of a global emissions source database called EDGAR and the structural design of the database system. The database estimates on a regional and grid basis, 1990 annual emissions of greenhouse gases, and of ozone depleting compounds from all known sources. (LZ)

Examines the potential for the replacement of CFCs for historic uses with substituting technologies. The potential production and emissions of the principal HCFCs and HFCs are calculated for the next 25 years. (LZ)

Describes an approximate document ranking process that uses a compact array of in-memory, low-precision approximations for document length. Combined with another rule for reducing the memory required by partial similarity accumulators, the approximation heuristic allows the ranking of large document collections using less than one byte of memory…

The Institute of Physics Publishing (IPP), a subsidiary body of the Institute of Physics (IOP), has used electronic publishing on the Internet as a major means of improving the speed of dissemination of physics information. The development of the Comprehensive Electronic Journals service is described along with recent enhancements and other…

Examines the Museum Educational Site Licensing (MESL) Project--a cooperative project between seven cultural heritage repositories and seven universities--as well as other developments of cultural heritage image databases for academic use. Reviews recent literature on image indexing and retrieval, interface design, and tool development, urging a…

Utilizes information gathered from archival and other documentary sources to develop greater understanding of the ways in which New Zealand's Native School system operated and was perceived by the Maori communities. Gives voice to former pupils of the Native Schools by establishing an oral-history database of their experiences within the school…

The study of database systems is typically core in undergraduate and postgraduate programmes related to computer science and information systems. However, one component of this curriculum that many learners have difficulty with is database analysis and design, an area that is critical to the development of modern information systems. This paper…

This paper reports on a study aiming to develop a metadata model for e-learning coordination based on semantic web languages. A survey of e-learning modes are done initially in order to identify content such as phases, activities, data schema, rules and relations, etc. relevant for a coordination model. In this respect, the study looks into the…
