Considers the legal response to terrorism following the September 11th attacks and questions whether American intelligence and law enforcement are positioned to protect the public in an effective manner. Highlights include the business of intelligence; the collection of information; use of technology; the need to improve information sharing; and…

Reviews the progress of parallel computing in information retrieval (IR) and stresses the importance of the motivation in using parallel computing for text retrieval. Analyzes parallel IR systems using a classification defined by Rasmussen; describes retrieval models used in parallel information processing; and suggests areas of needed research.…

Analyzes the amount of compression possible when arithmetic coding is used for text compression in conjunction with various input models. Algorithms are analyzed; modeling effects are considered; scaling is discussed; higher order models are examined, including prediction by partial matching; and coding effects are described.

Argues that educational theory and practice are dominated by a language frame that structures thought and practice into an input-output form. Outlines an alternative view of reflection and recursion based on the conversation postulate. A conversation is a system of mutually interacting components. Each component "perturbs" other…

Discussion of providing access to needed information focuses on five historical schemes that represent speculative approaches to solving the problem of restructuring and mobilizing the content of documents. The collection, analysis, and restructuring of information already available in some other form and the need for an information professional…

Draws on architecture and operation of human memory to better specify self-concept form and functioning. Translates these major components and processes of memory system into practice implications for targets and methods of change: declarative knowledge versus procedural knowledge, storage memory versus working memory, and role of sensory…

A meta-analysis of 31 experiments reported in 18 empirical bankruptcy prediction studies was conducted to test the effect of two information dimensions: information diversity and information repetitiveness. Results indicated that both information dimensions have an adverse impact on decision quality: provision of either diverse or repeated…

The learning organization concept tends to assume homogeneity of thinking, ignoring differences among individual members. The processes of transferring soft and hard knowledge may not be the same. Alternative organizational structures such as team, circular, or "hypertext" are needed for effective knowledge management and organizational…

Presents a multilevel model of the information filtering process that permits document classification. Evaluates a document classification approach based on a supervised learning algorithm, measures the accuracy of the algorithm in a neural network that was trained to classify medical documents on cell biology, and discusses filtering…

Examined the judgement of rectangular areas in young children who are blind from birth. Subjects were eight children ranging from six to eight years old. Their gestural strategies were examined in detail when placed in an area evaluation situation. Results indicated that acquisition of information concerning figures appeared to follow a fairly…

Focusing on John Searle's publication, "Rediscovering the Mind," in which he argues that the information processing view of the mind is seriously flawed, this article clarifies three issues: the relationship between conceptions of mind, knowledge, and education; some questionable assumptions related to the information processing view of…

In this paper, two empirical studies are presented in which an attempt was made to explain individual differences in two different aspects of 4-year-olds' suggestibility, that is, their ability to resist false suggestions and memory impairments due to prior misinformation. As sources of individual differences cognitive skills along the information…

Kanevsky (1995b) proposed a model of learning potential based on Vygotsky?s notions of "good learning" and the zone of proximal development. This study investigated the contributions of general knowledge, information processing efficiency, and metacognition to differences in the learning potential of 5 gifted nongifted students.…

The double-deficit model has been examined primarily in relation to reading. We investigated whether children classified according to the double-deficit model would exhibit differences in other neuropsychological domains. Children referred for learning problems (N = 188), ages 7 to 11, were classified by double-deficit subtype. Only three of the…

This paper provides a sequence of specific techniques and examples for implementing theatre voice training and technology in teaching ESL/EFL oral skills. A layered approach is proposed based on information processing theory in which the focus of learner attention is shifted in stages from the physiological to the linguistic and then to the…
