A procedure for approximating attained significance levels of exact conditional tests is proposed. The procedure utilizes a sampling from the null distribution of tables having the same marginal frequencies as the observed tables. (Author/JKS)

Two revisions of computer-interactive multidimensional scaling data selection procedures are presented. One revision--based on randomly ordering the list of stimuli--improves the estimates of the multidimensional scaling parameters and the other permits more efficient data designs. (Author/JKS)

An iterative procedure to obtain maximum likelihood estimates of latent structure analysis parameters is described. The procedure is defended against a critic (EJ 187 975) who contended that it would permit unacceptable estimates. (JKS)

Suggests that social science information services generally follow patterns set by science information services a decade or so earlier. Topics discussed include library research, the structure of communication and knowledge in the social sciences, communication patterns, shifts in methodology, and reassessment of achievements. (DB)

The effect of missing individuals upon the stability of the partition hierarchy yielded by the complete-link clustering technique was investigated. Empirical distributions of indices measuring the goodness-of-fit between partition hierarchies based on full and reduced sets of objects were obtained for data sets in which individuals were missing.…

While preserving the distinctive features of the case study, the case cluster method employs replicable sampling and, if desired, quantitative measurement procedures to complement qualitative analysis. It creates units of analysis that are based on theory and that have meaning for the actors and observers of the case. (Author/IRT)

A theoretical foundation is provided for a method of identifying those books in a library's stack that determine any given percentage of the current circulation. Basic components and requirements of the technique are described, and the theory is applied in an example that manipulates data from a university library. (Author/MBR)

Attempts to evaluate the hypothesis that rats are more hesitant to ingest novel-flavored substances while they are under the influence of a toxic agent than in the normal state. (Author/RK)

Questions the validity of a multiple-choice evaluation in which university students evaluated a lecture which had been cancelled. Comparison of this evaluation with evaluation of a film on sex and communication, which had been viewed by approximately 50 percent of the students, is offered. (Author/DB)

A total of 36 susceptible and 36 insusceptible subjects were tested to examine the effect of markedly contrasting styles of interpersonal orientation of the hypnotist on responsiveness in the hypnotic situation. (Editor)

Depicts a cognitive model for analyzing historical data that merges processes of logical reasoning and creative and critical thinking. The strategies presented provide an intellectual framework for the structure of historical inquiry. (SK)

Discusses the use of the least-squares regression line in determining the optimum straight line in an efficient and objective manner and the validity of its underlying assumptions in certain situations. Discusses the treatment of kinetic data, distortion from large errors, and the Guggenheim method. (JRH)

Applies the cognitive system engineering approach to investigate human-work interaction at a corporate setting. Reports preliminary analysis of data collected from diary analysis and interview of 20 subjects. Results identify three dimensions for each of four interactive activities involved in human-work interaction and their relationships.…

Discussion of collection analysis in school libraries focuses on the kinds of data used and how to use library automation software to collect the data. Describes the use of Microsoft Excel and its chart-making capabilities to enhance the presentation of the analysis and suggests ways to use collection analysis output. (LRW)
