Three tentative conclusions emerge from this study: (1) interviewer effect operates only when questions treat opinions and attitudes, (2) black respondents are more likely to identify "racially sensitive" problems as areas of high concern when speaking to black interviewers, and (3) militant blacks appear uninfluenced by the white…

It is possible to devise ingenious means for adapting basic methodological techniques to meet exigencies of the research situation while still meeting the requirements for the collection of valid data. (Author/AM)

The construction and interpretation of confidence intervals for the prediction of new cases in multiple regression analysis is explained. An example is provided. (JKS)

Kaufman and Sweet's article on the regression analysis of unbalanced factorial designs (EJ 111 767) is reviewed. A number of errors are noted, and relevant literature is cited. (GDC)

A single conceptual and theoretical framework for sampling any configuration of data from one or more population matrices is presented, integrating past designs and discussing implications for more general designs. The theory is based upon a generalization of the generalized symmetric mean approach for single matrix samples. (Author/CTM)

In a semestered system the school year is divided into two terms, with the first semester usually running from September to January and the second from February to June. Explores the effects of semestering and non-semestering on a number of classroom-process dimensions, e.g., curriculum, activities in the teaching-learning situation, and…

Applied research, as compared to basic nonapplied research, offers the potential for the development of unique insights into the nature of social theory. Cultural deprivation theorizing is used to illustrate the interplay between research and theory. (Author/CTM)

The quality of research on groups has been notoriously poor. This article is an attempt to respond to the research and evaluation deficit by providing some methodological approaches that might encourage group researchers and practitioners to attempt high quality research. (Author)

In a descriptive analysis of behavior management research with mentally retarded persons, data from 56 studies within a recent 5-year period is presented in four tables. (CL)

Available from: Arthur Retlaw and Associates, Inc., Suite 2080, 1603 Orrington Avenue, Evanston, Illinois 60201. Described is a study in which a large sample of children (n=444) with phenylketonuria (an inborn metabolic error usually related to impaired cognitive ability) were treated under controlled conditions from near birth to 6 years of age.…

Research hypotheses versus statistical hypotheses, null hypotheses and alternative hypotheses, and statistical significance versus practical significance are described and illustrated. (CP)

Analyzes 46 medical research papers on the effects of innovative versus standard surgical procedures on the health of patients. Results reveal that innovations generally reduce complications. The ethics of experimental surgery are also discussed. (CP)

Attempts to bridge the gap between psychological theory and implementation, with specific reference to the learning of color concepts in an art education program. Focuses on curiosity as a potentially valuable motivational resource in the classroom. (Author/RK)

Improvement in the research climate in children's librarianship is needed. There must be a determined demand for research, financial and job support for researchers, improvement in the research techniques for studying children, and implementation of actual research projects. Particular concerns include research on reading, school/public library…

This article presents lessons learned from an innovative employment and training program for dislocated workers. It provides specific information about program design and serves as a prototype for how social experimentation can be used by state and local governments. (Author/LMO)
