A partial least squares method is described for estimating parameters of linear structural relation models. This method is an extension of Herman Wold's proposal for estimation parameters without distributional assumptions, using some algorithms worked out by Paul Horst. The method (LISPLS) determines a different number of latent variables from…

This study was conducted in 1966 to provide the avionics fundamentals course, class A, with a number of tables for predicting academic performance, either by precourse variables or by grades made early in the course. A means of identifying potential setbacks and potential failures was also desired. In September 1966 a 16 week course replaced the…

Data from over 1,200 correlations reported in 38 studies concerning validity of aptitude and achievement predictors of success in high school vocational programs are summarized. Predictors investigated were (1) verbal intelligence, (2) nonverbal intelligence and abstract reasoning, (3) arithmetic reasoning, (4) spatial aptitude, (5) mechanical…

This report consists of three charts which present data on adoption patterns in New York City in the year 1976. The report is based on quarterly Child Welfare Information Service (CWIS) reports developed by Dave Fanshel and John Grundy. Each chart is accompanied by a brief explanatory text, and a summary of the findings. The charts present data on…

This study explored the relationship between classroom instructional processes and the average number of student absences in first and third grades. The data were collected in a total of 166 classrooms as part of the Follow Through Planned Variation Program. The Classroom Observation Instrument, developed by Stanford Research Institute, was used…

Utilizing a datafile compiled by Gene Summers from various censuses of governments publications, the following hypotheses were tested: (1) a relationship exists between county government revenue and the level of manufacturing, the size of the population in the county, and the median family income; and (2) a change in the former is due to changes…

A theoretical model is developed for analysis of intervention effects in multiple autocorrelated time-series which may be classified or blocked two ways. The intervention effect is estimated independently for each series. The estimates are then entered as observations in two-factor analysis of variance with one observation per cell, utilizing a…

To investigate the concurrent validity of the National Teacher Examinations, test scores of over 31,000 candidates were correlated with self-reported Grade Point Averages (GPA's). The overall correlation between the Weighted Common Examination Total (WCET) and GPA was .37. Validity indices for the Area Examinations ranged from .08 to .50 with a…

Three known methodological approaches were investigated as to their within-test correlative support in the measurement of a phenomena called imagery. Based on these methodologies, repeated dichotomization of subjects into high and low visualizers was significantly consistent. Moreover, self-reported ratings of imagery vividness of prose were…

The student sought to identify positive factors which might be used to increase the performance levels of students in vocational classes and to investigate the relationship between motivational characteristics (intrinsic and extrinsic) and individual performance. Subjects included students in typing and shorthand classes and their two instructors.…

This paper examines the relationship between the extent of shared participation of husbands and wives in leisure activities and the extent of communication and task sharing in the marriage. Because marriage is an interactional system and leisure activities vary in their interactional requirements, a theory is proposed linking leisure activity…

The early 1970's was a period of rapid decline for all fertility indicators in the United States. This paper explores some of the reasons for this decline. Data from a National longitudinal survey of young women are used to examine changes in expectations for lifetime births from 1971 to 1973. These young women decreased their birth expectations…

This monograph presents the first study of Negro police officers in Texas, the need for them and factors surrounding their use. It was felt that the need for Negro police officers was more than symbolic, and recommended fair representation in the agency that regulates their everyday life. Minority officers can provide a special competence in…

This monograph contains the second section, operations at the variable level, of a report of studies done in Helsinki, Finland, describing school achievement in terms of ability, trait, situational, and background variables. The report (1) investigates the structure of school achievement, (2) describes school achievement in terms of selected…

This study is phase one of a 4-year project. It was aimed at examining the predictive validity of six preschool screening instruments on later academic achievement. The six instruments were (1) the Stanford-Binet Intelligence Test, (2) the Sprigle School Readiness Screening Test, (3) the Anton Brenner Developmental Gestalt Test of School…
