Discusses some basic notions of modern cryptography: public key systems and digital signatures. Describes how theoretical modern cryptography can help solve security problems on the Internet. (Author/JKP)

Provides a succinct guide to building a home page. Overview includes the main Hypertext Mark-up Language (HTML) tags, plus examples of their use; forms and clickable maps; new HTML 3.0 tags; and pointers to sites that contain HTML editors, graphics, backgrounds, and music. Five figures illustrate the text. (JKP)

Examines fundamental questions about how people process numbers. Several cognitive numerical representations are defined. The current major theories of numerical cognition are described with emphasis on how they differ in their assumptions about numerical representations and how these differences are reflected in the positions taken on various…

Compared subjects' judgments about emotions expressed by the faces of infants pictured in slides to predictions made by the Max system of measuring emotional expression. Judgments did not coincide with Max predictions for fear, anger, sadness, and disgust. Results indicated that expressions of negative affect by infants are not fully…

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.

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)

This paper examines the need for a transcription system that allows the symbolization of nonnormal articulations. The paper then describes transcription systems proposed by clinical phoneticians and speech pathologists, especially PRDS (phonetic representation of disordered speech) symbols and extensions of the International Phonetic Alphabet.…

A coding method for measuring reflective thinking in student journals was tested twice, demonstrating acceptable reliability among evaluators and supporting the precision of the guidelines for coding. Coding categories were as follows: habitual action, introspection, thoughtful action, content reflection, process reflection, content and process…

At 2 sites information was collected from 168 workers, and their 3-letter Holland work environment codes were crossed with 3 measures of person-environment congruence. All three measures were strongly intercorrelated. The way a job was coded had a significant effect on the calculation of congruence. (SK)

Description of integrating one of the most widely used cryptosystems into a mathematics course for Liberal Arts majors. Application of this cryptosystem requires understanding of the concepts of exponentiation and modular arithmetic only. (MM)

Reading rate data was collected from both print and braille readers in the areas of mathematics and literary braille. Literary braille data was collected for contracted and uncontracted braille text with dropped whole-word contractions and part-word contractions as they would appear in the Unified English Braille Code. No significant differences…

Consistent with converging experimental evidence, we assume that foveal information is initially split across the two cerebral hemispheres. We have previously presented the SERIOL model of letter-position coding, which specifies how the resulting two halves of a letter string are integrated into an abstract representation of letter order. This…

The presentation of a subset of learned items as retrieval cues can have detrimental effects on recall of the remaining items. For 2 types of encoding conditions, the authors examined in 3 experiments whether such part-list cuing is a transient or a lasting phenomenon. Across the experiments, the detrimental effect of part-list cues was…

Three experiments are reported that examined whether stem complexity plays a role in inflecting polymorphemic words in language production. Experiment 1 showed that preparation effects for words with polymorphemic stems are larger when they are produced among words with constant inflectional structures compared to words with variable inflectional…

Drama at primary teaching course is given as a compulsory course to students enrolling department of the primary teaching in college of education in Turkey. In drama, assessment is problematic as the content of the lesson often deviates from the plan because of spontaneous input from the students and on-the-spot changes in direction by the…
