A unifying methodology of diffusion studies is presented treating geographical, sociological, and historical phonomena of language within the same framework. Patterns of linguistic innovation and the social and psychological motivations for such a change, both in the individual and in society, are summarized in their functions as predictors of…

The prediction that differences in incomes of high school and college graduates will not change is tested by applying standard statistical procedures to data describing actual income differences. Data from the United States Bureau of the Census describe annual incomes of men twenty-five years old and older during 1956-75. Report 1 displays results…

Experiments at three community colleges were conducted to examine the relationships among anxiety, performance, and two different methods of informing students of their instructor's evaluation of in-class speeches.

A study was conducted to examine the influence of parents' attitudes toward and use of media on their college-age children's media use and attitudes. Telephone interviews were conducted with 400 university students in the Northeast, and a questionnaire was sent to their parents. Both instruments measured media use variables, attitudes toward the…

Data obtained for 89 Title I reading projects were analyzed by multiple regression and discriminant function techniques to assess the relationships between project students' achievement and project characteristics. The results suggested that project characteristics specified in the Title I Evaluation and Reporting System (TIERS) data forms are…

Underrepresentation of women in higher status, traditionally male occupations has been attributed to sex-role socialization and to discrimination. Female students entering traditionally male professions may suffer many of the same pressures that have prevented other women from entering these fields.

Path analysis involves the construction of explicitly formulated causal models and makes the reasoning explicit in the form of path diagrams and structural equations. Regression analysis is then used to construct path…
