Factors identified for middle-class youngsters were found to be remarkably similar to those generated by their lower-class counterparts. (Authors)

Describes the techniques used to construct the Inventory of Societal Issues,'' and describes the seven scales that constitute the battery. All scales reflect environmental issues related to science and technology. (AL)

Purpose of this note is to point to an obvious but useful relationship by which estimation of individual factor scores can be omitted when obtaining relationships between factors and an external set of variables. (Author)

An algorithm, based upon factor analytic theory, is presented to illustrate one solution to the problem of selecting items for a test. (Authors)

Results of this research, while partially supportive of the general construct which the POI purports to measure, raises some questions about necessity of, or relevance of, the many scales of the inventory. (Authors/MB)

Results are given of a study to investigate trait and social desirability consistencies when subjects describe themselves by answering True or False to 90 trait terms. (DB)

A factor rotation scheme is presented which has a property that is interesting for examining factor-structure hypotheses. Given several clusters of tests the orthogonal bounds scheme produces factors which contains these clusters in some optimal sense. (Author)

A unified treatment of the before-after and after-pnly designs and their combinations is given. The paper tries to bring out clearly the type of information each design is capable of providing and under what conditions (assumptions) the results from each experiment can be given useful interpretations."

This article is concerned with the specification and estimation of relationships whose dependent variable is qualitative in nature (such as yes or no). It discusses logit equations with and without interaction, and the estimation procedure is generalized least squares. (Author)
