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)

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…

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…

The communication of four children with autistic spectrum disorder was investigated when they were supplied with a speech-generating device (SGD) in three different activities in their home environment: mealtime, story reading and "sharing experiences of the preschool day". An activity based communication analysis, in which collective and…

The orbitofrontal cortex (OBFc) has been suggested to code the motivational value of environmental stimuli and to use this information for the flexible guidance of goal-directed behavior. To examine whether information regarding reward prediction is quantitatively represented in the rat OBFc, neural activity was recorded during an olfactory…

Much previous research into the effectiveness of CMC has suffered from a lack of clarity or of consistency in the adoption and explication of coding typologies or taxonomies. This has reduced the opportunities for comparison between studies and for the accumulation of evidences to guide pedagogy. In addition, most studies of CMC have used…

Background: Many researchers are concerned with the proficiency of children in movement education. They are expressing this concern through the assessment of fundamental motor skills, owing to the established links between the proficiency of fundamental motor skills and subsequent involvement in sport and physical activity. The assessment of…

Since the 1920s, textbook critics have maintained that textbooks should offer a homogenous editorial approach, including an acknowledgment of a mix of author opinion and scholarly research. Several researchers indicated that some textbooks are not homogenous. The purpose of this quantitative content analysis study was to examine whether…

States have made dramatic progress in the past few years in implementing longitudinal data systems (LDS) to improve student achievement. These systems collect and house student educational data that make it easy for policymakers and practitioners to access and use it for reporting, policymaking and decision making. So much has happened in states…
