The determinants of widows' attitudes toward women were investigated, using social and personality variables known to discriminate attitudes in other marital status groups as well as variables reflecting the unique experiences of widowhood. The subjects were 118 urban widows, aged 29-78. Over 40 potential attitude predictors were assessed in…

The therapeutic efficacy of drug therapy and of psychotherapy for improving the condition of the mentally ill was examined. Results were tabulated of clinical drug trials in humans as reported in English language literature between 1954 and 1977, wherein a psychotropic drug was compared to a placebo or no treatment at all. Results of this…

Relationships among client sex bias, client sex, and therapist sex to therapy outcome were examined in four hypotheses: (1) Does sex of participants or initial client sex preference for a therapist affect treatment outcome? (2) Does exposure to a same or (3) opposite sex therapist affect attitudes toward the therapist? (4) Does client-perceived…

Defining metaphor as "seeing a concept from one class in terms of a concept from another class," a study was devised that analyzed the degree to which two concepts occupy dissimilar positions with respect to their category or domain (within-domain distance), and the degree to which categories themselves are dissimilar (between-domain distance).…

As a companion study to the primary analysis of the Management Implications of Team Teaching (MITT) study, the unitized schools in this study were examined alone for predictors of differential success in implementing the innovation. This report briefly describes how the MITT staff handled a problem in the companion study of reducing the number of…

A digital computer program, STAGEF, designed for use with the distillation experiments in a typical undergraduate Chemical Engineering laboratory in Unit Operations is explained. The program enables the student to determine the rate of liquid overflow and vapor boil-up which leaves each tray within the distillation column. The student may also…

The robustness of the Johnson-Neyman technique and analysis of covariance (ANCOVA) to violations of assumptions of homoscedasticity and homogeneity of variance was tested through the use of Monte Carlo computer procedures. The study simulated a one-way, fixed-effects analysis with two treatment groups, one criterion, Y, and one covariate, X. Five…

A procedure was developed within hypothesis-testing logic that allows researchers to support a hypothesis that has traditionally been the statistical or null hypothesis. Four activities involved in attainment of this goal were discussed: (1) development of statistical logic needed to define the sampling distribution associated with the hypothesis…

A general class of regression models for ordered categorised data is developed and discussed. Thier properties are contrasted with log linear models and other methods of analysis. The general problem of fitting by maximum likelihood is discussed and solved. The models are shown to be multivariate extensions of generalised linear models and the…

Rasch model vertical equating procedures were applied to three mathematics computation tests for grades six, seven, and eight. Each level of the test was composed of 45 items in three sets of 15 items, arranged in such a way that tests for adjacent grades had two sets (30 items) in common, and the sixth and eighth grades had 15 items in common. In…

Delinquency reduction and reduction of the number of juveniles referred to the justice system were assessed for 14 diversion programs in Los Angeles County. A project versus nonproject comparison and a pre-post analysis with archival and other data gathered from 1972 through 1977 were used. Preliminary results indicated that the diversion projects…

Methods for ordering and selecting variables for discriminant analysis in multiple group comparison or group prediction studies include: univariate Fs, stepwise analysis, learning discriminant function (LDF) variable correlations, communalities, LDF standardized coefficients, and weighted standardized coefficients. Five indices based on distance,…

A project was undertaken to integrate the 2F87F operational flight trainer into the program for training replacement patrol plane pilots. The objectives were to determine the potential of the simulator as a substitute environment for learning aircraft tasks and to effectively utilize the simulator in pilot training. The students involved in the…

Sixteen international experts comprised the working group charged with indexing technical and cost effectiveness studies related to new educational media. This report, resulting from their meeting in January 1975, contains: (1) introductory report on the problems of the application of cost benefit studies to new teaching methods, (2) series of…

This guide describes standard operating job procedures for the screening and grinding process of wastewater treatment facilities. The objective of this process is the removal of coarse materials from the raw waste stream for the protection of subsequent equipment and processes. The guide gives step-by-step instructions for safety inspection,…
