This technical report, produced in partnership by the Council for Advancement and Support of Education (CASE) and SPSS Inc., explores the promise of data mining alumni records at educational institutions. Working with individual alumni records from The Johns Hopkins Zanvyl Krieger School of Arts and Sciences, a predictive regression model is…

The purpose of the present study is to explore cost-effectiveness factors that affect the choice among alternative system designs for retrospective searching services. 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…

A statistical model for characterizing the growth patterns of data base utilization and for estimating future utilization levels of demand has been developed for information retrieval organizations. Illustrations of the model applied to a typical information retrieval organization are given and discussed. (5 references) (Author)

Designed to minimize information overload in telecommunications systems, the formal model developed in this paper predicts the usefulness of a message based on the available message features, and may be used to rank messages by expected importance or economic worth. The assumptions of binary and two Poisson independent probabilistic distributions…

The Florida R & D Utilization Project has two major goals: to provide schools with access to the best available R & D products and practices to resolve local needs, and to assist schools in developing a capacity for diagnosing and resolving instructional and other problems. This paper describes the 7-step conceptual model that governs the…

Defines library and information science as the creation, sorting, managing, and transferring of information. Introduces ODAPCOSRIU (origin, dissemination, acquisition, properties, classification, organization, storage, retrieval, interpretation and use) to help define it and explains I&OE (Inner and Outer Environment Model) as a graphic…

Describes a study that investigated how CEOs (Chief Executive Officers) in the Canadian publishing and telecommunications industries acquire and use information about the business environment. Topics discussed include environmental scanning; perceived environmental uncertainty; information sources; information use in decision making; and a…

Indicates that citation data conform to the Brookes model, that a scientific journal which is used as an archive ages slowly, and that one which supports a research front ages quickly--aging being dependent not only on the material, but on the user. (Author/SW)

Discusses two models of selecting information sources--Cost/Benefit (information seekers select sources on basis of expected benefits and costs), and Least-Effort (seekers select sources on basis of minimizing effort or cost). Results of a study proposing that users place different weights on costs and benefits are presented. (EJS)

Describes experiments relating information to decision making. The experiments were developed to validate previously suggested conceptual model of information flow and its relation to decision making and to establish specific values for significant parameters involved. Background and summary of recent research and experimental design and research…

Processing complex multivariate information effectively when relational properties of information sub-groups are ambiguous is difficult for man and man-machine systems. However, the information processing task is made easier through code study, cybernetic planning, and accurate display mechanisms. An exploratory laboratory study designed for the…

Discusses the concept of gatekeepers in the area of information and culture and presents a model for the information-seeking behavior of ethnolinguistic gatekeepers. Highlights include information needs and use models; information inequity in information and retrieval programs; affective and cognitive domains; and research implications for…

The objectives of the study presented in the dissertation were to identify present and anticipated information requirements of the various departments within the Oklahoma State Department of Vocational and Technical Education, to design a computerized information system model utilizing an integrated systems concept to meet information…

This paper examines the elements of user studies and presents them as unified concepts within a model of information-seeking behavior. Definitions of information-seeking behavior, information needs, information gathering, information giving, and source preference are discussed. Thirty-two references are cited. (EJS)

Low achieving, low socioeconomic students, because of a multiplicity of little-understood background factors, seem to fail not because of an initial lack of motivation to learn, but because basic learning processes taught them by their own communities are not contiguous with those required for academic success. The study attempts to determine if…
