Since the development of causal path analysis by Wright, both the standardized and unstandardized procedures in path coefficient estimates have been advocated in the related literature, but the superiority of one technique over the other has not been demonstrated empirically or mathematically. In this study, the sampling properties of both…

When Torgerson's multidimensional scaling model is used in conjunction with the method of tetrads, derived coordinates are based on data which is assumed to be distributed normally. The object of this study was to determine the amount of error contained in derived coordinates when the normality assumption is violated. Torgerson coordinates were…

Two alternative procedures for developing employment projections are evaluated, the Bureau of Labor Statistics' simple regression equation and the Florida fully specified econometric model. The simple equation was judged more cost effective and generally as useful as the fully specified model. (MF)

Immigrants have lower earnings than native born on their entry into the Canadian labor market. However, the younger the age at immigration, the greater the gain from immigration. (Author/AM)

The concept of structure is recast as an instantaneous correspondence between an infrastructure, a sociostructure, and a superstructure--manifestations of collective life juxtaposed through technological solutions, political exchanges, and social interpretations involving organizations. Ultimately, structuring is a dialectical unfolding of…

Presents a comparative analysis of Kaufman's and Nadler's work design models by examining each model's rational content and comparing the distinctive images of procedure that those contents project. Kaufman's insistent claim that his organizational elements model merits distinctive recognition as the definitive explication of the system approach…

A study comparing citations received by patents in given year to number received in subsequent years found that, even though influential patents remain influential, both highly and infrequently cited patents age at same rate. Distribution of patents by number of citations received is stable over time. (17 references) (EJS)

Two studies investigated two groups of young children at the ages of four and eight years, respectively. Subjects were required to solve a simple problem task by performing a response opposite to that demonstrated by an adult. Girls' performance was significantly worse than boys', regardless of the sex of the model. (Author/CI)

This paper compares the curriculum design model developed by R. W. Tyler (1902-1994) with a model of instructional design at Siena College, Albany, New York, as exemplified in a course taught by L. Stokes, professor of accounting. Tyler's model, which became the basis for many other models of instruction, consisted of four parts: (1) defining…

This paper examines how predictive modeling can be used to study application behavior. A relatively new technique, artificial neural networks (ANNs), was applied to help predict which students were likely to get into a large Research I university. Data were obtained from a university in Iowa. Two cohorts were used, each containing approximately…

This research assumes that systematic and systemic change are two components in instructional design (ID)--not dichotomous terms, but two sides of an interconnected dual structured system. Specifically, this paper examines the difference between systemic thinking and systematic thinking, the ideal mental model (dual structured systems) for ID, and…

This factor analytic study of the cosmopolitan-local construct was designed to overcome criticism of earlier research on the construct's dimensionality. Based upon the data from this study, commitment to specialized role skills appears to take on three different role orientations rather than the single orientation suggested by the literature.…

This paper focuses on a comparative analysis of the normative and empirical elements of four approaches to political education. The findings generally demonstrate that each approach has dramatically different normative and empirical implications for political education. (KM)

Two statistical models for estimating search time have been developed for the CA Condensates data base using the University of Georgia Text Search System. Comparative timings between the Chemical Abstracts Service search program and the University of Georgia search program are made for the Ca Condensates data base. (5 references) (Author/NH)

In experimentation where change in X produces a change in Y, the researcher must identify, measure, and control intervening variables by experimental design or statistical procedure. (Author)
