Discusses the problem of data redundancy in a fuzzy relational data model and describes three existing frameworks of fuzzy data representation and redundancy treatment. A new treatment based on Zadeh's extension principle is proposed. (18 references) (MES)

Defines and discusses bibliometrics, particularly as carried out in automated systems. The specific requirements to which data should conform to support bibliometric analysis are detailed and explained, and the Intelligent Gateway of the Lawrence Livermore National Laboratory is described. (15 references) (Author/CLB)

Provides critical analysis of Edwards (1992) presentation of a set of examples from the Child Language Data Exchange System as prototypes of bad transcription practice. The analysis argues that Edward's approach causes the development of an overly rigid set of principles that could stop progress in the analysis of spontaneous language samples.…

Presents the theoretical aspects of a data analysis methodology that can help transform sequential raw data from a database into useful information, using the statistical analysis of patents as an example. Topics discussed include relational analysis and a technology watch approach. (Contains 17 references.) (LRW)

Addresses the recognition of differences between clinical and research data in using computerized clinical nursing databases and the issues of privacy and confidentiality for patients whose records are involved. Describes procedures for assessing the quality and usability of these data for nursing research. (SK)

The information needed for informed decision making and planning by institutions of higher education can be made available through the establishment of carefully constructed databases. This handbook outlines the characteristics of databases, the needs databases meet, the key factors around which they must be organized, the advantages they offer,…

Surveys the field and literature of geographic information systems (GIS) and spatial data representation as it relates to GIS. Highlights include GIS terms, data types, and operations; vector representations and raster, or grid, representations; spatial indexing; elevation data representations; large spatial databases; and problem areas and future…

Administrators, faculty, and staff should have electronic access to records needed to perform their jobs, and students should have access to their own records--course registration and addresses. User-directed analysis and reporting are discussed and the security and audit issues are examined. (Author/MLW)

The authors of EC 610 840 reflect on their use of data from the federally developed National Education Longitudinal Study for their research. They identify specific weaknesses of their study stemming from use of this database (such as lack of severity data) as well as strengths (use of a national sample). Researchers are urged to utilize such…

The purpose of this report is to comment on practice in the use of existing data bases in program evaluation and school improvement and to explore directions of increased and improved use. The report's impetus is the role that existing data plays in current efforts in local school districts and the possibilities for the future. To a great extent,…

Providing researchers, especially those in the social sciences, with access to publicly collected microdata furthers research while advancing public policy goals in a democratic society. However, while technological improvements have eased remote access to these databases and enabled computer using researchers to perform sophisticated statistical…

This paper describes analytical concepts that can be applied to a comprehensive database containing information on students, teachers, and schools. The concepts are presented in terms of displays, potential inferences, and possible difficulties. Statistical techniques are mentioned, but not rigorously developed. Focus is on displays that can be…

Discussion of information management focuses on three main areas of activities and their interrelationship: (1) strategic, including establishing frameworks and principles of operations; (2) analytic, or research elements, including user needs assessment, data gathering, and data analysis; and (3) operational activities, including reference…

The paper addresses the potential of informatics to patient care quality assurance curricula, focusing on (1) terminology and developments related to quality of care evaluations; (2) criticisms of traditional approaches; (3) limitations of existing data sources for quality assurance in dentistry; and (4) quality assurance considerations in…

There are increasing numbers of commercially available computer graphics packages, both in terms of hardware and software, that can be utilized by instructors, practitioners, and students of education. With the proliferation of low-cost graphic terminals, time-sharing capabilities, and recent advances in mini- and microcomputers, computer graphics…
