Discusses the problem of duplicate citations resulting from file overlaps in multidatabase searching and shows that such duplicates could be identified automatically and eliminated by a host computer as a complementary service to online retrieval. Steps involved in the realization of this service are described, and 11 references are listed. (RBF)

Examines the computer networks as systems of power and focuses on the United States' domination of the hardware and software markets and on the international implications of this dominance. (JMF)

Explores whether plagiarism-detection services such as Turnitin.com, which keeps copies of submitted papers in a database, are trampling students' rights for the sake of academic integrity. (EV)

This guide is intended for use in a course to help students become familiar with computer disk operating systems and the applications of various types of computer software. The first third of the guide contains the following: a profile of the critical skills required for the Canadian work force, a flowchart of the recommended sequence of studies…

One agency introduced a computerized information-gathering system to answer such questions as: How many families, over what period of time, receive services? What are the costs for each part of the program? How is staff time distributed? The author describes benefits and difficulties that the changes brought about. (Author)

This report describes approaches to database translation (i.e., transferring data and data definitions from a source, either a database management system (DBMS) or a batch file, to a target DBMS), and recommends a method for representing the data structures of newly-proposed network and relational data models in a form suitable for database…

The accuracy and reliability aspects of data integrity are discussed, with an emphasis on the need for consistency in responsibility and authority. A variety of ways in which data integrity can be compromised are discussed. The following sources of data corruption are described, and the ease or difficulty of identification and suggested actions…

The report discusses the file management requirements of a computer-based information storage and retrieval system for the Language Information Network and Clearinghouse System (LINCS). It discusses a hypothetical structure for the LINCS system, requirements of file management, long-range trends in data management technology of interest to the…

This study of ranking algorithms used in a Boolean environment is based on an evaluation of factors affecting document ranking by information retrieval systems. The algorithms were decomposed into term weighting schemes and similarity measures, representatively selected from those known to exist in information retrieval environments, before being…

Although the indispensibility of access control mechanisms in data secure systems has been recognized, there is a need for more subtle protection and refined control mechanisms. This report describes context protection mechanisms which enable the same data unit to be protected differently in different contexts, the differences being determined by…

The OTIS Basic Index Access System (OBIAS) for searching the ERIC data base is described. This system offers two advantages over the previous system. First, search time has been halved, reducing the cost per search to an estimated $10 on a batch basis. Second, the "OTIS ERIC Descripter Catalog" which contains all descriptors used in the…

Organizational theorists alternatively hypothesized that computerized information systems (CIS) will produce no necessary changes, centralization, or decentralization in juvenile courts. This hypothesis is supported by the results of a four year study on the phenomenon. Suggestions are offered for improving the juvenile judicial system through…

Describes the operation and numerous capabilities of a British computerized data retrieval system named Prestel. It provides access, through the regular telephone network and a TV screen, to computer-based information supplied by many companies, agencies and commercial outlets. (GA)

Outlines the basic uses of computer systems and software programs by school administrators. Describes the different hardware and software needed to accomplish complex school administration. (MD)

The increasing data about institutions of higher education and the availability of this data are described and evaluated. The data bases need further development and coordination of standards, exchange guidelines, and accessing procedures to be most beneficial. (Author/LBH)
