An active program of information preparation and dissemination is necessary to assure that interpreters (administrative staff, teaching staff, parents, students, and others) are receiving, understanding, and transmitting unbiased information based upon fact. (MJB)

Specialists in communication theory and educational technology, working together, can make meaningful contributions to the knowledge needed to permit the use of media of all types to improve learning through the proper application of communication theory. (Author/STS)

Discusses the critical sociology of communication of the Frankfurt School suggesting that theorists such as Lowenthal, Adorno, and Habermas have outlined both the political economics of manipulation and the social psychological interaction between the audience and the media. (MH)

Contends that the transmission model of communication currently used by business communication teachers is too narrow and mechanistic in concept and suggests the need for a new model that is more descriptive of the communication process. (MH)

Presents a model and experimental results of a new one-phase technique for compression text files that is a modification of the Ziv and Lempel compression scheme. The description includes the use of a subword dictionary that is periodically reorganized based on information theory and structural linguistics principles. (29 references) (Author/CLB)

British Columbia remained committed to its decision to host a world's fair (Expo 86) despite rapidly increasing deficit projections. Expo is examined as a prototypical example of the escalation of commitment. Theory is proposed that integrates determinants of escalation from several levels of analysis over time. (CJH)

A common functional relationship among Lotka's law, Bradford's law, and Zipf's law is derived. The proof takes explicit account of the sequences of observed values of the variables by means of an index. This approach results in a more realistic and precise formulation of each law. (Author/EM)

Views information as residual or catalytic form of energy which regulates other forms of energy in natural and artificial systems. Parallel human information processing (production systems, algorithms, heuristics) and information measurement are discussed. Suggestions for future research in area of parallel information processing include a matrix…

It is shown that there is no ambiguity in Bradford's theory of distribution. Starting with two basic postulates laid down by Bradford, a mathematical expression is derived such that its curve agrees with the experimentally plotted data for periodicals in fields of applied geophysics and lubrication. Five references are listed. (Author/EJS)

The personal literature search of a scientist is strongly governed by subjective influences. If he delegates his query, he must be aware of the problems emanating from this subjectivity. The information scientist, on the other hand, must consider the subjective character of the fundamental notions of information and order. (33 references)…

Information integration theory is a unified general theory that covers several areas of psychology from psychophysics to clinical judgment. It rests on a mathematical basis that has had considerable success in some precise and demanding tests. (Author)

Analyzes the jargon of surgeons (with a high density of concrete items of information) and of logicians (emphasizing the relationships between statements), and discusses how these studies may be used in information retrieval. (AL)

The author suggests ways to overcome the conceptual and methodological limitations of studies involving campaign speaking and voting behavior. (Author/MF)

Adaptation of an address given on March 29, 1971 at the opening of the Twenty-fourth Annual Conference on World Affairs at the University of Colorado. (Editor)
