Extension faculty in Adams, Brown, and Highland Counties (Ohio) work as a cluster group to enhance interdisciplinary program delivery and develop specialized skills. Clustering also increases networking among clientele and enhances extension's public image. (SK)

Discusses the problem of processing fuzzy queries in databases and information retrieval systems and presents a prototype of a fuzzy query processing system for databases that is based on data clustering and uses Pascal programing language. Clustering schemes are explained, and the system architecture that uses natural language is described. (14…

Proposes and analyzes a method for servicing keyword queries expressed in a digital library. Topics include efficiency via the concept of customers and producers; grouping queries into clusters of similar concepts; information density of the library; query delay; query priorities; and fuzzy decision-making.

This study investigated the demographic, intrapersonal, and organizational factors associated with burnout among a population of school counselors in the northeastern United States (n = 78). Three hierarchical regression analyses were completed to determine the amount of variance that each cluster contributed to the 3 subscales on the Maslach…

Relational personality theorists propose that women have a tendency to view themselves in the context of relationships with others and to make decisions to optimize and maintain relationships. The current study explored whether relational identity may underlie women's career interests as measured by Holland's typology and examined possible…

Today's classrooms increasingly challenge teachers to address a diverse range of backgrounds, abilities, and learning needs. As teachers rise to the challenge, grouping can be a valuable instructional tool to address varying ability levels and learning needs within the classroom. At present, there is a good deal of support in the literature for…

Gary and Tall (2001) recently suggested that mathematics can be split up into "three worlds": the embodied, the proceptual and the axiomatic. They claim that objects from each of these worlds are formed, and reasoned about, in significantly different ways. During the course of this article the author considers the three world's theory…

In this study assumptions are made concerning the amount of clustering in sequences containing runs of equivalent elements. It is assumed that any valid clustering measure is linear with respect to union of runs and monotone increasing under iterations of clustering operators. With these two assumptions it follows that any such measure is of…

Studies of concept formation in infancy have demonstrated that certain experimental settings can elicit spontaneous behavior from infants which has been called "sorting" or "object grouping". This study pursues the issue of early sorting with infants as young as 6 months, and with a broader range of stimuli than has been used…

The objectives of this study were: (1) to create a set of computer programs capable of practical associative processing of NASA's growing document collection, (2) to process the collection with these programs, exhibiting the achievement of a capability to perform associative search of the collection, and (3) to study the use of statistical…

Dissimilarity Linkage Analysis (DLA) is an extremely simple procedure for developing a typology from empirical attributes that permits the clustering of entities. First the procedure develops a taxonomy of types from empirical attributes possessed by entities in the sample. Second, the procedure assigns entities to one, and only one, type in the…

The experiments involved 11,571 abstracts (with titles), 1,000 key-word stems and 93 search requests. Measures of word association are derived in several ways from the numbers of documents in which two given words co-occur, and measures of similarity from the numbers of words associated with both. Word clusters with different degrees of overlap…

Presents system for automatic handling of ordered sets, states based on these sets, and differing points of view regarding Universe of Discourse. Aspects are represented by new logical "overlap" function with examples taken from Ranganathan's horse and carriage parable and several books involving four main concepts (history, geography,…

Presents an exposition of two data reduction methods--single-link and complete-link hierarchical clustering. Emphasis is on statistical techniques for evaluating the adequacy of a completed partition hierarchy and the individual partitions within the sequence. A numerical reanalysis of data illustrates the methodology. (RC)
