Recent approaches to empirical derivation and validation of alcoholic subtypes which involve cluster analysis wihin a single multivariate assessment domain have been questioned. To investigate more clinically meaningful subtypes in a sample of 245 male alcoholics, cluster analysis was performed on a combination of variables from four assessment…

Compares two basic variants of the sorting method: single-sort and multiple sort. The nature of individual differences in sorting, as well as sex differences, were also investigated. Stimulus materials were the 15 mutually exclusive kinship terms selected by Wallace and Atkins (1960). (RC)

The author presents a communications-content domain model to assist educational planners create a graphics communications cluster which can better prepare students for a future of change. The concept of clustering is explored, especially in its applicability to graphics communications. (AJ)

Career education is probably best described as a group of concepts and processes, including career awareness, career exploration, infusion of career-oriented material with traditional educational resources, hands-on involvement, and participation in education by people normally employed in the world of work. Vocational education is simply one…

This report reviews the personnel literature on the development of job families to illustrate and provide examples of varied approaches to the taxonomic issues of objective, content, and method in job family construction. This booklet first examines the definition of job families and then briefly discusses the potential utility of job families.…

This paper reviews a variety of analytic procedures that can be applied to network data, discussing the assumptions and usefulness of each procedure when applied to the complexity of human communication. Special attention is paid to the network properties measured or implied by each procedure. Factor analysis and multidimensional scaling are among…

ONE OF THE PROBLEMS ENCOUNTERED IN CLUSTERING TECHNIQUES AS APPLIED TO DOCUMENT RETRIEVAL SYSTEMS USING BIBLIOGRAPHIC COUPLING DEVICES IS THAT THE COMPUTATIONAL EFFORT REQUIRED GROWS ROUGHLY AS THE SQUARE OF THE COLLECTION SIZE. IN THIS STUDY GRAPH THEORY IS APPLIED TO THIS PROBLEM BY FIRST MAPPING THE CITATION GRAPH OF THE DOCUMENT COLLECTION…

The method of organization in free recall in the form of either clustering or subjective organization is explored in this study. This is just one of the possible forms of retrieval that may be employed. Other possibilities include serial recall, alphabetization, and imagery. To the extent that subjects employ such other strategies, correlations…

Communication skills classes must prepare students for living and for earning a living. As the postsecondary technical-vocational schools throughout Wisconsin showed great differences in the content of their communication skills courses, both among schools and within various educational programs, a statewide survey was conducted to determine the…

In some educational research studies--particularly longitudinal studies requiring a probability sample of schools and spanning a wide range of grades--it is desirable to so select the sample that schools at different levels (e.g., elementary and secondary) "correspond." This has often proved unachievable, using standard methods of selecting school…

Besides the ubiquitous Pearson product-moment r, there are a number of other measures of relationship that are attenuated by errors of measurement and for which the relationship between true measures can be estimated. Among these are the correlation ratio (eta squared), Kelley's unbiased correlation ratio (epsilon squared), Hays' omega squared,…

To fill a need for defining and describing 15 occupational clusters identified by the U.S. Office of Education for a comprehensive career education program in a Texas county, this federally funded analysis presents separately for each of the 15 clusters a rationale, methodology, subgroupings into job families and occupational listings, and a chart…

Investigated the development and fragmentation of categories over chronological and mental age without the requisite of free recall. Kindergarten, fourth grade, ninth grade and retarded students labeled and categorized chromatic slides of picturable objects. (GO)

Describes study that compared and judged the quality of subject indexing in online bibliographic databases. Documents from medical behavioral science literature are used with terms drawn from MEDLINE, PsychINFO, BIOSIS, and Excerpta Medica. Comparative statistics are presented on how each database links related documents and discriminates among…

Discusses the issue of centralization or decentralization of academic library collections, and describes a statistical analysis of book circulation at the University of Southwestern Louisiana that yielded subject area clusters as a compromise solution to the problem. Applications of the cluster model for all types of library catalogs are…
