Discusses J. L. Austin's treatment of perlocution and extends it to an analysis of five types of perlocution. Proposes a set of conditions necessary and sufficient for consummation of any perlocutionary act. (JMF)

A computer program named TEXT-1 is intended for quantitative content analysis. Any text may be taken as input. The program provides frequencies of words, syllables, or letters in alphabetical order; frequencies of sentences, subordinate clauses, or quotations; and measures used in information theory. (Author/JKS)

George A. Miller's essay gives a clear account of information theory and demonstrates how the concept of limited channel capacity can be applied across sensory dimensions. Its major influence has been demonstrating that immediate memory span is relatively insensitive to the amount of information per item. (SLD)

Examines two models to study the consequences for coding efficiency of sample fluctuations, a specific type of error in the statistics on which data compression codes are based. The possibility that random fluctuation can be exploited for data compression is discussed. (six references) (KRN)

Examines information theory from the aspect of its conduit metaphor. An historical background shows how this metaphor was used to construct notions of language, information, information theory, and information science, and was used to extend the range of these notions across social and political space during the Cold War. (Author/LRW)

Chaos theory describes the way systems change over time. It proposes that systems governed by physical laws can undergo transitions to a highly irregular form of behavior and that although chaotic behavior appears random, it is governed by strict mathematical conditions. This paper applies chaos theory to administrative and organizational issues.…

This paper identifies the need for a new theory of information and develops a mathematical model which distinguishes between: (1) data, as directly observable facts; (2) information, as structured collections of data; and (3) knowledge, as methods of using information. The model is based on the ideas of the binary relational model and uses the…

History of international library and information organizations, as well as the status of communications among them, and the organizations' present role and future possibilities. (LS)

Describes the campaign by the National Council of Teachers of English Committee on Public Doublespeak to expose and denounce self-serving, deceptive, and sloppy uses of English. Also discusses the dangerous political and social implications of chronic language misuse by public officials, especially educators. (JG)

Addressing the problem of protecting confidential information and data stored in computer databases from access by unauthorized parties, this paper details coding schemes which present such astronomical work factors to potential code breakers that security breaches are hopeless in any practical sense. Two procedures which can be used to encode for…

AN ANNOTATED BIBLIOGRAPHY OF 20 ITEMS AND A DISCUSSION OF ITS SIGNIFICANCE WAS PRESENTED TO DESCRIBE CURRENT UTILIZATION OF SUBJECT THEORIES IN THE CONSTRUCTION OF AN EDUCATIONAL THEORY. ALSO, A THEORY MODEL WAS USED TO DEMONSTRATE CONSTRUCTION OF A SCIENTIFIC EDUCATIONAL THEORY. THE THEORY MODEL INCORPORATED SET THEORY (S), INFORMATION THEORY…

In view of the apparent complexity and dynamism of the learner, only a systems approach to learning processes can provide a viable and practical frame of reference within which to conduct educational research. There are fundamental weaknesses in the current cybernetic model of learning, and therefore, it is useful to consider the learner as an…

This study developed a variation of the DELPHI approach, a polling technique for systematically soliciting opinions from experts, to produce a technological forecast of developments in the information-processing industry. SEER (System for Event Evaluation and Review) combines the more desirable elements of existing techniques: (1) intuitive…
