Notes that researchers are often required to examine specific model under two different situations. Cites studies in which authors compared results descriptively without use of inferential statistics. Describes use of series of regression tests to compare two situations statistically. Gives example from recent study to illustrate technique.…

Notes that intergenerational theories of family functioning sparked interest in empirical investigations that test intergenerational relationships. Presents test of difference scores enabling researchers to compare related and unrelated dyads, thus creating comparison group when using only two generations. Contrasts procedure with correlational…

This report, based on information gained from multiple surveys of physicians conducted since 1980, addresses a number of basic public policy questions regarding physician manpower supply and distribution in the state of New York. The report's primary focus is longitudinal, attempting to identify patterns and trends among New York State's…

School context constrains and supports field researchers' data collection activities, just as it can influence the educational change processes being studied. For outsiders, the accessibility of a school is affected by a number of factors. These influence findings and have implications for achieving data comparability across several sites.…

Enumerates principal management objectives of database management systems (data independence, quality, security, multiuser access, central control) and criteria for comparison (response time, size, flexibility, other features).

Examines the influences contributing to greater population increases in some ethnic groups than natural increases would normally determine. The influences of interaction among time of arrival, overall fertility and mortality trends, differential fertility, intermarriage, and subjective identification are explored. (GLR)

Reexamined previous statistical comparisons of two models for adolescent drug abuse using new statistical estimation methods in causal modeling not requiring assumptions about normally distributed variables. An asymptotically distribution free method shows that the models fit even better than assumed in the initial work. (Author/JAC)

Tested models of interests by examining the significance of disconfirmed ordinal predictions. Examined data regarding Holland's hexagonal model and Roe's circular ordering. Tested adequacy of the hierarchical model and compared significance of the disconfirmed predictions of the hierachical model to that of the hexagonal-circular model. (Author)

This report provides results of a study that measured lender profitability in the Guaranteed Student Loan (GSL) program and compares these results with the profitability of other types of lending.
