Discussion of communication within organizations and with the outside world focuses on results of a survey of managers in 41 companies that assessed intraorganizational and interorganizational uses of email. Describes the use of factor analysis and regression methodologies to investigate whether a significant relationship existed between internal…

Tests the properties of a Spanish version of the Family Adaptability and Cohesion Scales III (FACES III) in a Spanish sample. Confirmatory factor analyses replicated the factor structure of the original American version. Reliability coeffecients were higher for the cohesion than the adaptability scale. Convergent and discriminant validity was…

Examined the asymptotic distributions of three reliability coefficient estimates: (1) sample coefficient alpha; (2) reliability estimate of a composite score following factor analysis; and (3) maximal reliability of a linear combination of item scores after factor analysis. Findings show that normal theory based asymptotic distributions for these…

Derived formulas for the asymptotic standard errors of component loading estimates to cover the cases of principal component analysis for unstandardized and standardized variables with orthogonal and oblique rotations. Used the formulas with a real correlation matrix of 355 subjects who took 12 psychological tests. (SLD)

Describes a national survey in which 7 public library constituent groups rated the degree to which 61 indicators helped describe a library. Dimensions of effectiveness were then developed through factor analysis on the indicator choices. A full list of indicators, a list of collapsed indicators, and the results of the factor analysis are appended.…

This study investigated the relationship of baud rate, searcher experience, performance anxiety, and search outcome in the performance of an online bibliographic search. A significant interaction of baud rate and experience was observed, as well as a relationship between anxiety and search performance. Results contain implications for training and…

The effects of using a unidimensional item response theory (IRT) model were compared with two-dimensional data generated by non-compensatory and compensatory multidimensional IRT models. The number-correct distributions for each dataset group were comparable, although factor analyses of tetrachoric correlations suggested differences in data…

A coefficient derived from communalities of test parts represents greatest lower bound to Guttman's "immediate retest reliability." Constrained minimum trace factor analysis allows a consistent estimate of the greatest defensible internal-consistency coefficient. In modest size samples, this analysis capitalizes on chance, suggesting an…

This study examined Type I error and power properties of the rank transform test when used in the context of a balanced 2 x 2 x 2 fixed effects analysis of variance (ANOVA). The rank transform procedure was erratic with respect to both Type I error and power. (TJH)

It is argued that the methods suggested previously by Bejar are a valuable descriptive tool for assessing the unidimensionality assumption when a priori information is available about possible response factors. (SLD)

In FACTALS, an alternating least squares algorithm is used to fit the common factor analysis model to multivariate data. A. Mooijaart (1984) demonstrated that the algorithm is based on an erroneous assumption. This paper gives a proper solution for the loss function used in FACTALS. (Author/TJH)

An alternative to the PROMAX exploratory method is presented for constructing a target matrix in Procrustean rotation in factor analysis. A technique is proposed based on vector majorization. The approach is illustrated with several standard numerical examples. (SLD)

Describes study comparing views of husbands and wives toward day-to-day communication practices. Initial data analysis yielded 24 items contributing to 7 factors. Wives tended to report less communication or rate communication lower than husbands, but both husbands and wives were generally satisfied with communication in marriages. (Author/CRR)

Two Statistical Analysis System (SAS) macros are presented that perform the modified principal components approach of L. R. Tucker (1966) to modeling generalized learning curves analysis up to a rotation of the components. Three SAS macros are described that rotate the factor patterns to have characteristics Tucker considered desirable. (SLD)

Develops, examines, and confirms a four-factor conceptual model of defensiveness as (1) a self-perceived flaw the individual refuses to admit; (2) a sensitivity to that flaw; and (3) an attack by another person that (4) focuses on an area or issue that the attacker perceives as a flaw in the other.
