A general approach is described for the analysis of categorical data when there are missing values on one or more observed variables. The method is based on generalized linear models with composite links. Situations in which the model can be used are described. (SLD)

The arbitrariness of linguistic categories is discussed. Consideration of some other fields of human activity suggests that the Sapir-Whorf hypothesis is true, and it is suggested that the process of grammaticalization might be understood as a kind of ritualization. (57 references) (Author/LB)

Neural network technology was compared with simultaneous and stepwise linear discriminant analysis in terms of their ability to classify and predict persons (n=138) as having autism or mental retardation. The neural network methodology was superior in both classifying groups and in generalizing to new cases that were not part of the training…

Presents a taxonomy of information that may be useful in dealing with the protection of intellectual property. Information is examined as an activity; as a life form, including the desire to change; and as a relationship, including value, authority, execution of ideas, and economic issues. (LRW)

Examines the nature of literate behavior in the pretend play episodes of eight preschoolers. A taxonomy of pretend play activity is described and analyzed based on the findings. Relationships between different kinds of pretend play activity and their effect on emergent literacy development are examined in light of the taxonomy and other research.…

Places rhetoric of science in context with sociology, psychology, history, and philosophy of science. Generates a typology of concerns for rhetoric of science. Characterizes the central issues of the field. (RS)

Mathematical relationships between three-mode component analysis and stationary component analysis are explored. Theorems are presented giving constraints that must be satisfied for equivalency between component representations provided by the methods. In general, the two approaches give mathematically distinct representations. (SLD)

The term "adult education" was used in the United States in the late nineteenth century. Melvil Dewey developed a typology of adult education, and Henry Leipziger promoted New York City's Free Lectures program as an institute of liberal adult education. Leipziger's advocacy was largely responsible for the diffusion of the new term in its…

On picture matching and word recall tasks, children performed better on slot-fillers, or items classed in a superordinate category (such as food) and in the same event context (such as eating breakfast), than on coordinates, or items classed in a superordinate category but in different event contexts. (BC)

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.…

Claims implicit scientific paradigms of Diagnostic and Statistical Manual of Mental Disorders-III-Revised (DSM-III-R) and family therapy to be incompatible. Notes DSM-III-R views symptoms arising from processes occurring within individuals while family therapy sees symptoms as arising from processes occurring within family systems. Suggests…

This study attempted to empirically demonstrate the validity of a twofold classification of speech disfluency in adult stutterers. Instrumentation and procedures permitting reliable identification and coding of 9 disfluency behaviors were developed and applied to monologues of 180 adult stutterers. Factor analyses supported the two-factor…

Arguments against a standardized language for nursing interventions are inflexibility, concern for clinical usefulness, and diminished professional judgment. Proponents argue that it will help develop nursing information systems, communicate the nature of nursing, and expand nursing knowledge. (SK)

A rule-plus-exception model (RULEX) of classification learning is proposed. According to RULEX, people learn to classify objects by forming simple logical rules and remembering occasional exceptions to these rules. Because the learning process is stochastic, people will vary in the rules formed and exceptions stored. (SLD)

Used event-related potentials to determine whether infants show differences in spatial and temporal characteristics of brain activation during face and object recognition. Found that infants' experience with specific examples within categories and their general category knowledge influenced the neural correlates of visual processing. (Author/KB)
