The "k"-means clustering method, while widely embraced in college student typology research, is often misunderstood and misapplied. Many researchers regard "k"-means as a near-universal solution for uncovering homogeneous student groups, believing its success hinges primarily on the selection of an appropriate "k."…

ABC analysis is a well-established categorization technique based on the Pareto Principle for determining which items should get priority in the management of a company's inventory. In discussing this topic, today's operations management and supply chain textbooks focus on dollar volume as the sole criterion for performing the categorization. The…

Although a variety of studies have indicated that using statistical clustering techniques to examine genetic information may allow for geographically based groupings of individuals that tenuously map onto some conceptions of race, these studies have also indicated that the amount of genetic variation within these groupings is significantly larger…

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…

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…

Discusses the lack of classification systems as a major deficiency in the field of comparative education. Examines previous typologies of education systems and of forms of intergroup relations. Offers a tentative classification of 135 national education systems based on 15 conventional indicators using factor analysis and cluster analysis.…

Discusses intellectual issues involved in the indexing of visual images, postulating that the indexing of images should provide access to images based on the attributes of those images and provide access to useful groupings of images. Four categories of image attributes are described, and issues to be considered in creating groups are discussed.…

This report represents one aspect of the development of a competency-based, interdisciplinary cooperative program called Project SAVE (Special And Vocational Education). It focuses on Phase I, which, using a taxonomic approach, analyzed prior research and development efforts directed at implementing competency-based personnel preparation programs.…
