Great educators of history were categorized on the basis of their: aims of education, fundamental ideas, and educational theories. They were classed by Ward's method of hierarchical analysis into six groupings: Socrates, Ausonius, Jerome, Abelard; Quintilian, Origen, Melanchthon, Ascham, Loyola; Alciun, Comenius; Vittorino, Basedow, Pestalozzi,…

Presents a document-clustering algorithm that uses a term frequency vector for each document in a Japanese collection to produce a hierarchy in the form of a document classification tree. Introduces an application of this algorithm to a Japanese-to-English translation-aid system. (Author/LRW)

Introduces a new approach for partitioning test items into dimensionally distinct item clusters. The core of this approach is a new item-pair conditional-covariance-based proximity measure that can be used with hierarchical cluster analysis. The procedure can correctly classify, on average, over 90% of the items for correlations as high as 0.9.…

Discusses hierarchic document clustering in information retrieval and its potential improved effectiveness over inverted file search (IFS). Describes experiments conducted to determine whether hierarchic clustering can increase the retrieval effectiveness compared to both static clustering and of conventional IFS when it is applied to search…

In a study exploring the relationship between typology and risk, we investigated the daily routines of a heterogeneous sample of young men and women from two sites who had been homeless for varying periods (N=1289). Cluster analysis yielded four groups--"Partnered", "Socially engaged", "Service connected-harm avoidant", and "Transgressive"--based…

A study with students enrolled at an urban technical college compared learning of HTML coding across three Web-based program versions. One group received examples providing factual information about the source code (Facts group). A second group was presented with a step-by-step description of the source code (Procedures group). The third group was…

The present paper tackles the issue of the higher education funding system in Slovenia. Its main attribute is that institutions are classified into study groups according to their fields of education, and funds granted by the state are based on their weights or study group factors (SGF). Analysis conducted using data envelopment analysis tested…

Frender and Doubilet suggest that Bousfield's ratio of repetitions (RR) is the best measure of clustering in free recall presently available. Conditioning only on the number of words recalled, they determine the mean of RR in the absence of clustering. In this note the null variance of RR is presented. (Author)

The Standard Occupational Classification is a new approach to classifying occupations being developed that will furnish a coding system and nomenclature to meet the varied needs of those concerned with identifying, classifying, and coding occupations. (Author/BP)

Develops and illustrates a method for clustering hierarchically the interrelationships between many persons, as represented in a matrix of a thousand by a thousand. (RC)

In free recall learning, taxonomic organization has been studied almost to the exclusion of alternative types of organization. Consequently, little is known about how learning and memory are affected by alternative types of organizations. The present experiments explored the differential effects of two kinds of organization on free recall…

THE RELATIONSHIPS BETWEEN SCHOOL GENERATED ANXIETY AND VARIOUS INDICES OF SCHOOL ACHIEVEMENT, CREATIVITY, AGE, AND IQ, ARE INVESTIGATED. A 160 ITEM, MULTIPLE-CHOICE, MULTI-SCALE, SCHOOL ANXIETY QUESTIONNAIRE WAS ADMINISTERED TO 56 FOURTH, FIFTH, AND SIXTH GRADE CHILDREN WITH A MEAN STANFORD BINET IQ OF 126 FROM AN UPPER MIDDLE CLASS COMMUNITY.…

An empirical assesssment of the space distortion properties of two prototypic hierarchical clustering procedures is given in terms of an occupancy model developed from combinatorics. Using one simple example, the single-link and complete-link clustering strategies now in common use in the behavioral sciences are empirically shown to be space…

A pattern-analytical technique, Similar Response Analysis (SRA), was developed, validated with contrived data, verified using previously reported data based on other pattern-analytical methods, and used successfully with "real" data. This technique orders subjects on the basis of the similarity of responses of adjacent individuals, not…

The Claremont Colleges started the first US cluster experiment in 1925. Through the cluster concept, the personal values of the small college have been preserved while it secured facilities of the university. What is not known is whether educational resources have been enriched at a faster rate than the rise in unit cost. The purpose of this study…
