Using the notion of parallel items this paper presents a family of new criteria for cluster analysis. (Author)

Authors conclude that, in the world of real data sample correlation matrices, Guttman's stronger lower bound is not of practical use in determining the effective number of common factors. (Authors/CB)

Certain noneconomic factors in collective bargaining are directly related to the negotiator's personal inclination to settle for the new contract. In this study, the pattern of relationships between the parties, the nature of the work itself, favorable recognition, team policy, and interpersonal relationships proved to be significantly related to…

The broad objective of this study then, is to attempt to discover whether a set of environmental variables presumably of significance for cognitive growth, generates similar factor structures across groups of varying socioeconomic status. (Author)

Authors attempted to measure a few key variables associated with the Porter-Lawler (1968) expectancy model in order to determine its validity. (Author/RK)

A 40 item, Likert type attitude inventory was completed by a sample fo 448 teachers in schools with sixth forms. Implications for policy making in the area of sixth form education are briefly discussed. (Editor)

The present research was stimulated by three related problems frequently faced in validation research: viable procedures for combining similar jobs in order to assess the validity of various predictors, for assessing groups of jobs represented in previous validity studies, and for assessing the applicability of validity findings between units.…

The present study suggests that although the reliability of an academic aptitude test given under formula-score condition can be increased substantially through empirical option weighting, much of the increase is due to the capitalization of the keying procedure on omitting tendencies which are reliable but not valid.

Maximum likelihood factor analysis provides an effective method for estimation of factor matrices and a useful test statistic in the likelihood ratio for rejection of overly simple factor models. A reliability coefficient is proposed for analysis of factor solution. (Author/RK)

The school district fiscal capacity data (1962 and 1967) of the National Finance Project were analyzed for psychometric adequacy and robustness of component composition. The procedures involved: (1) the computation of the Kaiser, Meyer, Olkin Measure of Sampling Adequacy, (2) inspection of the off-diagonal elements of the antiimage covariance…
