Hollingsworth recently showed a posttest contrast for analysis of variance situations that, for equal sample sizes, had several favorable qualities. However, for unequal sample sizes, the contrast fails to achieve status as a maximized contrast; thus, separate testing of the contrast is required. (Author/GSK)

Data evolving from processes which are developmental or hierarchical in nature are often analyzed by using latent class or latent structure models. A procedure for estimating such models when the model is not "identifiable" is presented. (JKS)

A study on the readability of publications of the Florida Cooperative Extension Service shows that most are written at the 12th-grade level, though the average Floridian reads at the sixth-grade level. The materials present a barrier to comprehension by limited-resource audiences in Florida. (JOW)

The model set forth in this article makes it possible to describe and judge an educational program (specifically, nursing) on the basis of data obtained through a specified inquiry process. It provides a systematic method for organizing various types of data and allows the examination of relationships among those data. (CT)

In designing an institutional advancement survey, it is thought that the researcher must have a clear conception of the survey's purpose. The relationship of research to theory, the nature of the survey, data collection, and analysis and interpretation are discussed. (Author/MLW)

Discusses methods for designing search strategies for maximum recall, including minimizing the number of concepts intersected, isolating key subtopics, adapting the strategy to the database, and minimizing problems with search words and codes. (Author/RAA)

Describes a paper-and-pencil method for producing reaction-time data suitable for group situations. The technique was constructed to contrast the two traditional theoretical approaches to semantic memory but can be applied to other questions of cognitive psychology. (Author/CK)

Introduces this special volume whose purpose it is to encourage the further development of qualitative study as a way of increasing the diversity of the field, thus increasing the sources of insight and discovery. (Author/IRT)

A full understanding of how a training program works requires field observations that examine the deep structure as well as the surface behavior of those in the program. Such comprehensive understanding is not available from questionnaires and interviews. (Author/IRT)

Addresses the issues and problems in analysis of qualitative data through a review of experiences in a four-year project that relied centrally on such data. Asserts that the attractive aspects of qualitative research are real and that the nuisances can be reduced by thoughtful methodological inquiry. (Author/IRT)

Discusses the need in designing educational studies to give more attention to recognizing the universe of generalization and to incorporate into the design a variable that represents the universe. Data analytic techniques should treat the levels of this variable as randomly selected from the universe. (Author/JEG)

Investigates the relationship between the mean age of psychotic veterans hospitalized for suicidal or nonsuicidal behavior and the presence or absence of childhood onychophagia. (Author/RK)

Discusses the rationale behind the "before-after" experimental paradigm used by Keren (1976) in his Experiment I (AA 525 466). (Editor/RK)

Schoolboys from the Ivory Coast and from Kenya were tested on a simple task intended to detect the effect of implicit-shape constancy. (Editor)

The conclusion of Cohen that there was no significant difference between the mean levels of open-closed mindedness for mature-age and younger students is questioned. (Editor)
