Using parameter estimates the computer program calculates the negative hypergeometric distribution and computes the classification proportions: suitable-accepted, suitable-not accepted, not suitable-accepted, and not suitable-not accepted. (RC)

Wechsler Memory Scale-Revised (WMS-R) scores were analyzed for 82 epilepsy surgery candidates and used in combination with receiver operating characteristic curves to classify patients with left (LTL) and right (RTL) temporal lobe seizure onset. Results indicate that WMS-R scores used alone or in combination provide relatively poor discrimination…

Examines concepts and types of organizational commitment and factors common to all commitments. Conceives of commitment as a single, fundamental construct that varies in focus, terms, and time-specific evaluation. (SK)

Using data from an academic nursing center that cared for 3,263 patients over eight months, diseases were classified using International Classification of Diseases codes, and procedures were classified using Current Procedural Terminology codes. Patterns of health care emerged, with implications for clinical teaching. (SK)

Continues earlier research on the development of a new definition of information science and the creation of a map of the field showing subjects central to it and their relationship to those on the periphery. A case study describes the creation of a new classification structure for the "Information Science Abstracts" database.…

Discusses reusable digital learning resources or objects in distance education and training. Focuses on the pivotal role of metadata and issues relating to classification, description, and meaning, specifically issues of semantics; and describes the CanCore Learning Object Metadata Application Profile. (Author/LRW)

Two experiments examined whether Deaf signers or hearing nonsigners exhibit categorical perception (CP) for hand configuration or for place of articulation in American Sign Language. Findings that signers and nonsigners performed similarly suggests that these categories in American Sign Language have a perceptual as well as a linguistic basis.…

Describes an activity in which students learn about sorting and classifying. Involves students determining what animal or geometric figure is on their back by asking their peers yes/no questions. (JRH)

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.…

Explains the concept of a semantic Web where software agents perform jobs for end-users by using hierarchies, metadata, and structured vocabularies. Discusses taxonomies; defining ontologies and taxonomies; standardized language and conceptual relationships; different points of emphasis; and topic maps as new Web infrastructure. (LRW)

Discusses students' learning engagement and describes a study that investigated whether teachers could accurately judge elementary school students' learning engagement with educational software. Explains teacher's use of a seven-level taxonomy to rate the frequency of different forms of engagement among 42 students interacting with different types…

Presents an instructional approach that goes beyond memorization of new vocabulary in a unit on classification to engage students in cooperative learning activities. Students work in six teams differentiated by taxonomic level to create skits, models, a Mollusk Fashion Show, and pictures. In a final activity, students create their own…

Three studies investigated whether children, ages 2-7, recognized facial expressions by category. Study 1 focused on emotion categories of happiness and anger; Study 2, on sex differences, with sadness added. Study 3 was on 2- and 3-year-olds. All three studies showed a Label Superiority Effect, in which emotion labels resulted in more accurate…

Examined personality variables in vocationally undecided college students (n=510). Classified five subtypes of vocational undecidedness according to each subtype's characteristics: anxiety, self-esteem, work, relationship or leisure orientation, locus of control, vocational identity, perception of barriers, need for information, and…

Discusses the inconsistent and shifting ways in which the U.S. Census treats race, color, and ethnicity. Suggests that long-term conceptual frameworks be developed so that the next census will not produce uneven categories based on unequal assumptions. (EVL)
