The present paper discusses two rather different types of partitioning techniques that still have the same property of monotone invariance. (Author)

Paper is an attempt to extend the hierarchical partitioning algorithms and to emphasize a general connection between these clustering procedures and the mathematical theory of lattices. (Author)

This study proposes and investigates file ordering and retrieval techniques which, it is hypothesized, will: (a) reduce the average cost of retrieving records which satisfy a query, and (b) increase the rate of retrieval in the initial portion of the response period. (8 references) (Author)

Describes a recently opened middle school building in Templeton, Wisconsin, introducing clustered classes, movable walls, and teaching teams. (LN)

Educators in technical education should resolve major differences in philosophy and get on with the basic task of training technicians. (JS)

The Smoking Control Research Project showed that most smokers wish to quit and that many of them can. It is necessary to present these smokers with the opportunities to quit, and then make the environment supportive of nonsmoking. Presented at the University of California Extension Course, "Cigarette Smoking: Insight into a Perplexing Problem,"…

Many different systems have been developed for classifying occupations. A few of the major systems are described here, along with an idea of the kind of information collected and published by the agency using the system. (Author/SSH)

Investigated two dimensions of a typology of police officers: perspective and passion. Test results indicate these dimensions failed to identify the four police types proposed by W.K. Muir relating to dimensions of: the professional, enforcer, reciprocator, and avoider. The four types appear as general characters defined by several dimensions.…

The clustering of teacher centers facilitates teacher sharing of information and resources, encourages professional development, and assists in the change and development of the centers. (JD)

Describes ways of using Boolean questions with a clustered information file, and reviews an experiment studying the effect of such a retrieval method. (FM)

Discusses mapping science and Kuhn's theories of paradigms and scientific development. Highlights include cocitation clustering; bibliometric definition of a paradigm; specialty dynamics; pathways through science; a new Web tool called Essential Science Indicators (ESI) for studying the structure of science; and microrevolutions. (Author/LRW)

Identifies 24 thematic categories among research articles appearing in the first 10 volumes of the journal. Notes that predominant themes were test reliability and validity, acculturation and adaptation of Hispanics, and bilingual/language issues. Indicates three major clusters of researchers publishing on Hispanic issues. (SV)

Discusses models for the distribution of words in text and proposes a new model based on clustering that can be used to estimate the probability that a document contains a particular word as well as the number of distinct words in a document. Zipf's law and the Poisson approximation are also discussed. (18 references) (LRW)
