Learning analytics and digital badges are emerging research fields in educational science. They both show promise for enhancing student retention in higher education, where withdrawals prior to degree completion remain at about 30% in Organisation for Economic Cooperation and Development member countries. This integrative review provides an…

Reviews the major write-once read-many (WORM) optical-disk products and systems demonstrated at the 1987 Association of Image and Information Management conference. Products are grouped as follows: (1) disk drives and jukeboxes; (2) systems integrators and value-added resellers; (3) turnkey systems; and (4) read-only systems. Addresses for 38…

Provides specific information on varying photographic materials and processes to aid archivists and curators in preserving photograph collections. Preservation problems related to major types of silver prints on paper (salt, albumen, collodion, gelatin) and to the silver image (oxidation, silver sulfide) are covered. Twenty references are cited.…

Reviews the state of information technologies involving teletext, viewdata, interactive graphics, videodisc, audio synthesis, and holography, and discusses the current understanding of access schemes and cognitive processing. Sixteen suggested readings and nine references are cited. (FM)

Discusses various optical disk formats, including 5 1/4 inch and smaller, 12-inch, and 14-inch. Typical applications and factors to be considered in format selection are covered. (MES)

Explores the information storage potential of videodiscs through comparisons of several videodisc sytems now on the market or under development. A table shows compared costs and storage capacities for microfiche, floppy discs, and three types of videodisc systems. (SW)

Describes recent attempts to make explicit connections between the indexing process and the use of the index or information retrieval system, particularly the utility-theoretic and automatic indexing models of William Cooper and Stephen Harter. Theory and performance, information storage and retrieval, search stage feedback, and indexing are also…

Discussion of issues surrounding the microcomputer's capability to download online search results covers types of downloading; scope of downloading; legal issues (copyright and database contract provisions and policies); and effects of downloading (widespread pricing changes, and provision of database subsets by database producers). (MBR)

Discusses developments in the application of computer and microform technologies to the storage and management of large map collections, including online cataloging systems, digital databases, videodiscs, microfilm, and the role of map librarians. A bibliography lists more than 70 sources. (FM)

This 14-item annotated literature review summarizes and analyzes scientific developments in and applications of optical and videodisc technology. Implications for information storage and retrieval, prospects for the optical disc in the office, preservation and the new technology, electronic document delivery, and the impact of technology on…

Developments in the representation of music, in notated and acoustic forms, in computerized databases suggest a need for nontext searching. Examines aspects of music notation and sound and reviews literature concerned with basic considerations of musical document representation; systems for encoding music for storage, regeneration, and analysis;…

Reviews several noncyclical, nonrepetitive hypotheses that try to predict broad spectrum maturational stages of overall information technology growth. Based on the areas of convergence among the hypotheses, several predictions are offered, and it is suggested that we are at a major transition point entering the third stage of computerized…

Describes the latest technology in videotape cassette systems and other magnetic storage devices and their possible effects on optical data disks. Highlights include Honeywell's Very Large Data Store (VLDS); Exabyte's tape cartridge storage system; standards for tape drives; and Masstor System's videotape cartridge system. (LRW)

Examines design functions of present file organizations in the context of available data storage devices and identifies current developmental trends. (Author/RAA)

Reviews the literature relating to the development and application of modern imaging technology between 1987 and 1993. Highlights include image representation, including image data, compression, and image formats; and image access, including indexing and modeling, user interface design, and distributed access.
