AbstractA replication of the Alpert‐Raiffa probability assessment experiment is used to motivate the development of several tests for evaluating assessors. The tests permit an evaluation of an assessor's accuracy in estimating target quantities and in estimating his own uncertainty as well.Assumption of normal subjective distributions permits the determination of subjective variances. Data from trial assessments are employed to test models which assert that assessed quantities are equal to subjectively assessed error variances. Several tests of the latter type are compared using data from individual, as well as pooled, assessors.

ABSTRACTThe authors believe that marketing applications of the semantic differential have not sufficiently explored the potential of the standard scales developed by the initiators of the semantic differential. The current study was undertaken to test the feasibility of a standard semantic differential instrument in store image measurement. The sets of scale evaluations of five department stores by forty female subjects were subjected to principle component analyses followed by a rotation for simple structure. The separate analyses for each store suggested certain similarities in the semantic space employed by subjects to judge quite dissimilar stores. A single analysis over subjects and stores simultaneously revealed a strong evaluative factor, a potency factor and a novelty factor, but no separate activity factor. These factors appear closely identified with honesty, femininity, and novelty as judgmental attributes of stores. This semantic structure is regarded as highly suggestive, but its utility in an ongoing managerial framework has yet to be proven.

ABSTRACTThis paper describes the use of moderated regression in job redesign decisions. The procedures outlined are intended to augment the job redesign strategy described by Hackman and his colleagues. Different regression models based on a theory of job design are shown to lead to different job redesign decisions. Comparisons are also made between the moderated regression procedures and the more commonly used subgroups analysis.
