Reports research results into a methodology for determining similarity between queries characterized by Boolean search request formulations and discusses similarity measures for Boolean combinations of index terms. Rationale behind these measures is outlined, and conditions ensuring their equivalence are identified. Results of an experiment…

Describes method of automatic document classification in which documents classed as QA by Library of Congress classification system were clustered at six thresholds by keyword using single link technique. Automatically generated clusters were compared to Library of Congress subclasses, and partial classified hierarchy was formed. Twelve references…

In this monograph, a causal-comparative, longitudinal study of cluster grouping at the elementary level is described and recommendations are made based on the findings. This study employed both quantitative and qualitative methodologies. The primary purpose of the study was to examine the effects of an existing cluster grouping program on the…

Used a new statistical procedure to examine consensual beliefs about situations common to universities. This approach aims at constructing a joint hierarchical or non-hierarchical classification of situational categories. Results indicate that a psychologically meaningful and methodologically satisfactory representation of the cognitive…

Presents the results of research into the automatic selection of Library of Congress Classification numbers based on the titles and subject headings in MARC records from a test database at the University of California at Berkeley Library School library. Classification clustering and matching techniques are described. (44 references) (LRW)

Describes five gifted elementary students and their programs: an Alaskan classroom delivery model centered on cluster grouping and differentiated thematic curricula; an Oregon pullout program focused on leadership and social skills; an Idaho hybrid program utilizing curriculum compacting; a Montana classroom model personalized at the building…

Infants parse speech into word-sized units according to biases that develop in the first year. One bias, present before the age of 7 months, is to cluster syllables that tend to co-occur. The present computational research demonstrates that this statistical clustering bias could lead to the extraction of speech sequences that are actual words,…

The purpose of the study was to describe the needs of newly released Canadian federal offenders as perceived by community parole supervisors. Seventy-four Canadian parole supervisors were asked to answer the following question: "What challenges do parolees face in the first 90 days after release?" The data were analyzed using…

Ultrasound can be used to address unresolved questions in phonological theory. To date, some studies have shown that results from ultrasound imaging can shed light on how differences in phonological elements are implemented. Phenomena that have been investigated include transitional schwa, vowel coalescence, and transparent vowels. A study of…

This paper describes school improvement through clusters (or leagues) of the Colorado Department of Education. School improvement clusters are defined as associations of schools and cooperating organizations dedicated to improving the quality of education. Participants work together with a common goal or unifying concept. The paper describes 14…

A new typology for faculty is proposed, based on their expressed priorities toward activities in which research universities engage. Responses of 617 faculty to a survey of 66 statements about university activities were factor analyzed, and scores on eight factors obtained were used in a cluster analysis that produced three clusters of faculty.…

Results are presented of the Nursing Delineation Pilot Study, which was conducted in 1981-1982 as part of a nursing project to develop a coordinated statewide system of nursing education in Kentucky. Gilpatrick's Health Services Mobility Study Method of Task Analysis and Curriculum Design (1977) was used to identify and describe tasks of different…

The goal of this project was to find ways of enhancing the efficiency of searching machine readable data bases. Ways are sought to transfer to the computer some of the tasks that are normally performed by the user, i.e., to further automate information retrieval. Four experiments were conducted to test the feasibility of a sequential processing…

Confirmatory factor analysis is presented as providing appropriate techniques for the analysis and evaluation of questionnaires and tests if the content of the measure can be identified as consisting of groups of items, with each group measuring only a single trait. This approach is contrasted with latent trait theory which assumes (and does not…
