A Factor Analytic Comparison of Ecological and Individual Correlations: Some Methodological Implications

Comparisons of factor analytic results based on a matrix of total (individual) correlations and three matrices of between-groups (ecological) correlations revealed fundamental differences in factor patterns when the unit of analysis shifted from individuals to aggregates. The major difference involved the marked tendency for a highly individualistic General Ability Factor derived from the matrix of total correlations to become more and more sociological in content as individuals were aggregated. Results are discussed in terms of their bearing on the problem of determining the "appropriateness" of a given unit of analysis, individuals vs. aggregates, for certain levels of inquiry, i.e., psychological vs. sociological. It is concluded that whether the researcher should heed the traditional warning about the use of aggregate data relationships as a basis for making inferences concerning individuals ought to depend in part on whether his interest is in psychological or sociological propositions about indivduals.     

Movement and structure as determinants of spatial representations

It was hypothesized that the cognitive representation of distances between locations in an environment is a function not only of the environment's structure, but also of a person's pattern of travel within the environment. In the present study subjects were exposed to an experimental environment in which some locations were separated either by an opaque or a transparent barrier and other locations were not separated by any barrier. As subjects learned where the locations were, they were required to follow a specific route that allowed travel between some locations in each category but not others. Afterward subjects were asked to reproduce from memory the separation between pairs of locations. The results supported the hypothesis. Recalled distance between locations was significantly affected by both movement patterns of subjects and structural aspects of the environment (type of barrier and actual separation between locations). These results are interpreted in terms of the types of information made available through particular movement patterns and the corresponding salience of that information.     

Main Street U.S.A.: A Comparison/Contrast of Streetscapes in Disneyland and Walt Disney World

All visitors to Disneyland and Walt Disney World must enter the “magic kingdoms” by way of Main Street, U.S.A.—the Disney version of a small town landscape of around the turn of the century, the “classical period” in American streetscape evolution. Extending far beyond its park setting, Disney's idealized Main Street (along with the overall design of which it is a part) is “one of the most successfully designed streetscapes in human history,” and has exerted enormous impact. Its design and images have influenced city and new town planning and the restoration of real Main Streets across the country, inspiring architectural restoration philosophy and practice; in short, writing an important chapter in the history of America's fondest image of itself. It was in fact from the ranks of planners and designers, not academic intellectuals or even social commentators (who scorned and reviled Disney's creations), that the initial awareness and appreciation of theme parks as structures and images came, as a leading edge in the breakthrough in perception of popular environments which has occurred only within the past decade. Richard Francaviglia is concerned with the architecture and design of Main Street U.S.A. as it preserves, controls, modifies and perpetuates a central collective image. But he goes further, comparing the original articulation in California with the Florida version a design generation later. What is ultimately revealing is the contrast of both of these related but distinct ideals within the parks to Main Street as it actually existed.     

Information in experiments and sufficiency

We define measures of information contained in an experiment which are by-products of the parametric measures of Fisher, Vajda, Mathai and Boekee and the non-parametric measures of Bhattacharyya, Rényi, Matusita, Kagan and Csiszár. We use these measures to compare sufficient experiments according to Blackwell's definition. In particular, we prove that if δ_X and δ_Y are two experiments and δ_X≥δ_Y then l_X≥l_y for all of the above measures.     

The Nonconsequences of Objective and Subjective Status Inconsistency: Requiem for a Moribund Concept*

Though long suggested, subjective indicators of status inconsistency have seen little empirical use. Data from a sample survey with controls for additive status variables are used to compare objective and subjective status inconsistency with these conclusions: (1) Individuals in an “objective” state of educational-occupational inconsistency are no more likely to feel inconsistent than those whose objective statuses are aligned. (2) When considered in conjunction with vertical status dimensions, neither objective nor subjective status inconsistency is independently associated with measures of social participation; only the subjective measure is independently associated with powerlessness. (3) The joint use of subjective and objective status inconsistency concepts in future work must be carefully justified and must take into account well-substantiated but frequently ignored methodological problems.
