Purpose: The purpose of this paper is to develop a test for data centres, repositories and archives to determine OAIS functional model conformance. The test developed was carried out among the World Data Centre (WDC) member data centres. The method used to develop the OAIS functional model conformance test is discussed, along with the test…

The primary purpose of this study is to determine how students are impacted by the use of Classroom Response System (CRS) technology. This research explores the nature of the outcomes experienced by students and their perceptions on the leading pedagogy and practices for using CRS technology in the classroom. The research is both quantitative and…

Information systems are becoming more than computer systems, with new equipment and techniques combining with data processing to form a new field called information technology. The emerging discipline of systems engineering is discussed along with nine systems engineering techniques. An organization chart of an information services department is…

A model which relates the access control and indexing functions. The model is based on concept protection which allows a practically unbounded number of levels (subsets) of protection without requiring a fixed hierarchy among the levels. This protection is offered independently for each of the user operations allowed. (Author)

The frequent reference by geographers and cartographers to 'the language of maps' is made precise by clarifying ways in which maps and other formulations of geographic information constitute a language. Aspects of this language are identified, and emphasis is placed on the use of linguistic concepts for study of models of geographic information…

A model of a generalized information storage and retrieval system is proposed. The model consists of six subsystems (or blocks): logical processor, selector, descriptor, file, locator, document file, and analysis block. These subsystems function in a partial environment defined by the user and data blocks. Proceeding from a verbal description, a…

The purpose of this study was to explore cost-effectiveness factors that affect the choice among alternative systems. A cost-effectiveness model that may be used to evaluate potential systems was derived and a statement of the general magnitude of costs that the American Psychological Association (APA) can expect in implementing and operating…

This appendix outlines the ComField information management system which is designed to give the project management a comprehensive tool for decisionmaking and to free instructors from tasks of keeping current records of every student's performance, help them plan their time more efficiently for counseling students and planning instruction, and…

The benefits of prototyping as a basis for system design include better specifications, earlier discovery of omissions and extensions, and the likelihood of salvaging much of the effort expended on the prototype. Risks and methods of prototyping during rapid systems development are also noted. (Author/MLW)

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…

Examines four working steps from an empirical model where an expert abstractor discovers what a paper is about and drafts a topic sentence; a simulation system is developed using this model. Discusses knowledge processing activities of professional summarizing. Results indicate that a small simulation model of professional summarizing is feasible.…

Improvement of information systems to support management and planning in education is dependent on a change to a rational management style. It can be argued that this same prerequisite exists for the return of public confidence and support. (Author)

The reliability and maintainability (R&M) model described in this report represents an important portion of a larger effort called the Digital Avionics Information System (DAIS) Life Cycle Cost (LCC) Study. The R&M model is the first of three models that comprise a modeling system for use in LCC analysis of avionics systems. The total…

THE PURPOSES OF THIS STUDY WERE TO DEVELOP A MODEL FOR COMPARING VOCATIONAL JOB PLACEMENT WITH ENROLLMENT AND TO MAKE RECOMMENDATIONS FOR ITS APPLICATION ON A STATEWIDE BASIS. THE MODEL WAS ESTABLISHED THROUGH SEARCHING LITERATURE, CONSULTING WITH EDUCATORS AND ELECTRONIC DATA PROGRAMERS, AND OBSERVING EXISTING PROGRAMS. IT WAS ESSENTIALLY A DATA…

The purpose of this article is to set forth a conceptual framework to help educational administrators understand the applications and potential of data processing activities in their institutions. It is expected that such a framework will provide a basis for data processing decisions and direction for future data processing activities. The model…
