This first of two related reports by the same authors presents a generalized theory of the information flow process that establishes quantitative definitions for and relationships among quantity of information, value of information, effectiveness of information, decision-maker effectiveness, and decision-maker performance. Eighteen references are…

Restates A. D. Baddeley's hypothesis about the limited capacity for information processing: an individual's limited capacity to handle information (including production and storage), although presumably never reached in actual performance, exercises a definable constraint on performance. (RL)

Describes an experiment investigating the use of structural constraints and surface semantics by modeling experts. Results indicated that when interpreting information models, modeling experts focus on the structural constraints and ignore the surface semantics, even in situations where structural constraints contradict real world situations.…

An information-theoretic framework is used to analyze the knowledge content in multivariate cross-classified data. Proposes measures based on the information concept, including the knowledge content of a cross classification, its terseness, and the separability of one variable. Presents applications for situations when classical analysis is…

Makes the case that the effectiveness of the use of information systems (IS) in an organization depends on an evolving understanding of the nature of IS value and that the speed of this organization is, in large part, a function of organizational and IS leadership. Analyzes the role of leadership and its relationship to the concept of absorptive…

An inquiry into the origins of dynamical awareness shows that impressions of dynamical quantities are not generally correlated with the values that these quantities take in equations of motion but are highly correlated with simple ratios of kinematic quantities or with specific kinematic features that do not specify underlying dynamics.

Many of the puzzles of absolute judgment raised by George A. Miller in 1956 remain puzzles today. Literature directed toward capacity limitations in absolute judgment tasks and in short-term memory is reviewed, and some models that attempt to elucidate the phenomena are discussed. (SLD)

Compares the notion of the conservation or inconservation of information with the laws of conservation of matter and energy. The theory of entropy in physics and its significance in information theory is discussed, and the essential nature of information is considered. (LRW)

Applies prevailing conceptions of proper argument to Burke's advocacy of the comic frame. Concludes these common conceptions cannot explain the power of Burke's arguments. Examines Richard Rorty's "edifying discourse" and Burke's "perspective by incongruity" as they illuminate the purpose of Burke's argumentation method. (NH)

Refines the basic entity model of information theory and extends it to analyze mathematically the physical symbol transformation characteristics, as well as energy-matter and cognition phenomena occurring in the human mind. Reviews existing theories; examines physical symbol subsystem, cognitive perspective, energy-matter subsystem; and discusses…

Uses a case study from information-seeking studies to analyze theory growth in information science, differentiating three contexts: unit theories, theoretical research programs, and metatheories. Illustrates the usefulness of tools in the analysis of theory growth by reconstructing a theory used in current information-seeking study. Includes a…

Presents the semantic information theory, formulated by the philosopher Fred Dretske, as a contribution to the discussion of metatheories and their practical implications in library and information science. Highlights include mathematical communication theory; digitization, perception, cognition, and concept formation; information and knowledge;…

Purpose: The purpose of the paper is to evaluate the effectiveness or success of universities' portal implementation from the perspective of students as users. Adopting the model developed by Delone and McLean, portal effectiveness is defined as being composed of information quality, systems quality and service quality. In addition, the paper also…

In this paper, an evaluation of web sites regarded like projects is discussed. We give an overview of the Web Assessment Index (WAI), by presenting a web sites of Romanian Faculties of Economics case study. The WAI contains five categories: accessibility, access speed, navigability, content and reliability. We analyzed and presented a detailed…

Background: Research about sport pedagogy has recently emerged as a significant interest in student reflective practice within the PE teaching/learning system. This learning process is considered as a type of knowledge of co-construction in action. This epistemological assumption postulates that the "knowledge-in-action" is the result of an active…
