This paper discusses research on how concepts differ in their internal organization and how these differences interact with and affect cognitive processing in children. Two types of natural concepts are focused on: classes (nouns with class-inclusion organization, such as "trees,""students,""soldiers" and collections…

Designed primarily as a basic reference to assist researchers and planners in the study of factors related to occupational mobility and skill transfer within and between occupations, this catalog consists of two major sections. Section 1 contains the abstracts of the data bases. These abstracts include selected key variables organized in a…

GIVEN THE TASK OF LEARNING A SERIES OF RANDOMLY ORDERED MEANINGFUL ITEMS, MOST SUBJECTS (SS) IMPOSE SOME ORGANIZATION ON THE MATERIAL DURING THE PROCESS OF LEARNING. AN EXPERIMENTAL PARADIGM IS DESCRIBED WHICH PERMITS THE OBJECTIVE SCORING OF EACH S'S SUBJECTIVE ORGANIZATION OF THE MATERIAL ON EACH LEARNING TRIAL. THE CENTRAL FEATURE OF THE…

A series of experiments was performed to investigate the effectiveness and utility of automatically classifying documents through the use of multiple discriminant functions. Classification is accomplished by computing the distance from the mean vector of each category to the vector of observed frequencies of a document and assigning the document…

To support studies in automatic indexing, classification and extracting, a general purpose frequency program was developed to further theoretical and practical understanding of text word distributions. While the program is primarily designed for counting strings of character-oriented data, it can be used without change for counting any items which…

A brief review of reading research studies is presented, and the need for unifying reading theories is discussed. It is noted that speed training, comprehension skills, and vocabulary development compose the main areas of reading research and that most of the studies are taxonomic and do not give accurate explanations or allow for predictions and…

A fundamental problem in the two broad approaches to indexing in the social sciences--providing structure using preferred terms, cross references, and groupings of sets of materials, or compiling a concordance of an author's terms based on occurrence, leaving users free to impose their own structure--is that different indexers and users focus on…

Libraries in Utah have collected large numbers of materials on Mormonism and related topics and have a need to provide more detailed subject headings for these materials which the Library of Congress has lumped together under "Mormons and Mormonism." A list of subject headings which was developed for this purpose by a Committee of the…

Appropriate subject headings were developed for Oklahoma government agencies in conjunction with the cataloging of 1,000 Oklahoma state publications. The Anglo-American Cataloging Rules (AACR) were followed as closely as possible, although in some instances established headings which were not in conformity with AACR were retained. Appropriate…

Because Q-technique is as appropriate for use with visual and design items as for use with words, it is not stymied by the topics one is likely to encounter in graphics research. In particular Q-technique is suitable for studying the so-called "congeniality" of typography, for various copytesting usages, and for multivariate graphics research. The…

The classification scheme for textbooks in the Education Library at the University of Texas at El Paso is described in this report. The scheme, developed to allow quick retrieval and yet give consideration to time and expense, is in card format, and (1) divides textbooks into Elementary (K-6) or Secondary (7-A); (2) further divides into general…

The study explored the feasibility of deriving an educationally relevant occupational cluster structure based on Occupational Analysis Inventory (OAI) work dimensions. A hierarchical cluster analysis was applied to the factor score profiles of 814 occupations on 22 higher-order OAI work dimensions. From that analysis, 73 occupational clusters were…

The process of revising the National Center for Higher Education Management Systems (NCHEMS) Program Classification Structure (PCS) is now completed. This document is being distributed to inform NCHEMS constituents about the final revisions to the PCS and to describe the reasons why each revision was made. The revision process began in early 1974…

This paper indicates why the use of "Category Systems" provides a potential for making precise and valid cross-cultural comparisons of classroom behaviors not equaled by other techniques. The paper is presented to highlight a technique which seems especially suitable for use by comparative educators and other social scientists who wish to make…

Intended as an introduction to mental retardation, the booklet provides information on definitions, incidence, etiology, diagnostic tests, developmental characteristics of persons with varying degrees of retardation, habilitation services (such as community programs, residential care and special education), and preventive measures.
