In this essay, the author "maps" a town that has grown in what was formerly frontier: he looked at twenty-four essays focusing on grammar instruction from "Teaching English in the Two-Year College (TETYC)," published between 1987 and 2006, with a goal of identifying key areas of focus--town squares. While he found several trends and foci, most…

This paper discusses visual communication theory. After an examination of the literature, this study built a more extensive bibliography of visual communication in general--theory, research, teaching--as well as a taxonomy that was better grounded. A 95-page bibliography was developed for works from a number of scholarly journals dealing with…

The single-link cluster method is used to construct a hierarchic classification for the 1400 documents in the Cranfield test collection. A variety of retrieval strategies applied to this hierarchy are evaluated in terms of effectiveness and efficiency. (Author)

A classification of propositions (consisting of a verb and its arguments) is presented with a stipulation of the properties of each type, and clarification is given for how the classfication and the properties function in the interaction between propositions and Japanese aspectual auxiliary verbs. The different types of verbs include: (1) state…

Reports the results of experiments in document clustering using three well-known test collections. (Author)

Measuring object similarity using the method of free clustering is gaining in popularity. Instructions are usually simple and since no structure is imposed on the subject's selection, response bias is reduced. More importantly, measures of object similarity derived from the judges' clustering can be adequately analyzed by the methods of…

The study explored the feasibility of deriving an educationally relevant occupational cluster structure based on Occupational Analysis Inventory (OAI) work dimensions. A hierarchical cluster analysis was applied to the factor score profiles of 814 occupations on 22 higher-order OAI work dimensions. From that analysis, 73 occupational clusters were…

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…

This is a methodological study that suggests a taxometric technique for objective classification of yeasts. It makes use of the minres method of factor analysis and groups strains of yeast according to their factor profiles. The similarities are judged in the higher-dimensional space determined by the factor analysis, but otherwise rely on the…

A method of typological analysis was applied to computer-generated 96-item questionnaire data for 100 cases, under a variety of conditions to analyze both the item-level and score-level. The results showed a considerable advantage of score-level approach in the number, size, and replicability of clusters recovered. (DEP)

Inspection of findings from Denney and Ziobrowski (1972), in light of problems of analysis and method, seriously questioned the validity of their reported crossover interaction of clustering criteria with age. In addition, a replication of their experiment, correcting for methodological problems, revealed no interaction of clustering criteria with…

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)

Systems theories of personality often describe subsystems (such as conscious and unconscious) and subsubsystems (such as ego, id, and superego). This paper classifies the major systems theories of personality in terms of the number of levels in their analysis. (Author)

The processes by which Roe (1956) and Holland (1966) developed their structural representations of occupations are compared. Roe, using almost exclusively nonempirical means, formulated an eight-group circumplex, virtually identical to Holland's six-group hexagonal configuration that resulted from empirical research spanning 11 years. The…

This summer 2003 issue of New Directions for Community Colleges advances the conversation among researchers and practitioners about possible approaches to classifying two-year colleges. The 10 chapters include the following: (1) "Classifying Two-Year Colleges: Purposes, Possibilities and Pitfalls" (Alexander C. McCormick and Rebecca D.…
