Introduced are information retrieval strategies based on automatic hierarchic clustering of documents. Cluster-based strategies are shown to be as effective as, and more efficient than, linear associative retrieval. (47 references) (Author/SJ)

ISDED, designed as an international classification system but adaptable to national systems, is an inter-departmental project of Unesco administered by the Office of Statistics. A three stage, five digit system by level, field and programme, ISCED consists of over 450 categories of education with their respective definitions. (JB)

A method is described for bifurcating a matrix of objects into two submatrices such that the sum of average deviations of the members from the central tendencies of the two submatrices is minimized. Illustrations of the procedure are included. (DG)

A description is given of a general method for studying partitions. The main focus is with the analysis of relationships among several different partitions of the same items for the explorations as well as confirmation of structural relationships. A partition is defined as a set of mutually exclusive clusters of items; however, this paper deals…

A relatively reliable and valid hierarchy of clusters of objects is plotted from the highest column entries, exclusively, of a matrix of interassociations between the objects. Having developed out of a loose definition of types, the method isolates both loose and highly definitive types, and all those in between. (Author/RC)

Tests for and identifies populations within a family of electronics industries. Data include 669 United States and 144 Japanese electronics firms. Demonstrates the relevance of a general organizational classification for explaining how different natural selection processes affect different populations. (75 references) (MLF)

The "cluster college arrangement" is discussed in this model for reorganization of the College of DuPage. The basic idea is to provide, within the framework of the parent institution, several educational communities small enough to enable students and faculty members to work closely toward reasonable educational goals. The following…

Results show the major effect of word association over rhyming as an organizational basis in a list where either or both types are possible. (Author/MB)

This study, based on a PhD dissertation submitted to UCLA and supported by the National Institutes of Health, indicates the extent to which children vary in the type of organization they impose on stimuli and the extent to which organization can be influenced by training. (Author/AP)

Findings provide information about developmental differences in sorting and recall, as well as evidence that organizational training may influence recall performance. (Authors)
