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)

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)

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

Both acquisition and retention were better when the hierarchy was learned graphically rather than as a list of associations, although the effect was greater on acquisition than on retention. (Authors)

Two hundred twenty-seven organizational units drawn from a variety of industries were cluster-analyzed on the basis of their similarities across 18 behavioral and structural dimensions of effectiveness. Using a multivariate subgrouping procedure, eight homogeneous clusters of units were found, varying in size from 8-65 units, and each…
