The purpose of this study was to analyze the nature of the relationship between energy conservation attitudes and behaviors of adolescents in the use of energy for personal and family-related activities. Specifically, the study was designed to determine a level of attitude-behavior consistency for each respondent and cor responding levels of selected attitudinal qualities. The association of selected demographic characteristics and attitude-behavior consistency was also deter mined. Data were collected from 227 eleventh and twelfth grade students en rolled in both urban and rural public schools. The dependent variable was the attitude-behavior consistency score. Independent variables included demo graphic characteristics as well as levels of attitudinal quality defined as affective, cognitive, and direct experience. The relationship existing between attitude and behavior was tested using correlational statistical analysis. Multiple regression, factorial analysis of variance, and t-tests were used to determine significant sources of variance upon the consistency score. Energy conservation attitudes and behaviors of adolescents were found to be significantly correlated. Differ ences in the consistency of attitude and behavior were found to be significantly associated with sex and employment of adolescents. No significant differences in consistency were found to be associated with other demographic variables tested or with levels of attitudinal qualities measured.  相似文献

The paper examines two approaches to the omitted variable problem. Both of them try to correct for the omitted variable bias by specifying several equations in which the unobservable appears. The first approach assumes that the common left out variable is the only thing connecting the residuals from these equations, making it possible to extract this common factor and control for it. The second approach relies on building a model of the unobservable, by specifying observable variables which are causally related to it. A combination of these two methods is applied to the 1964 CPS-NORC veterans sample in order to evaluate the bias in income- schooling regressions caused by the omission of an unobservable initial ‘ability’ variable.  相似文献
