Results of two studies are reported, in which we compare the predictive power of three general behavioral antecedents (i.e., values, worldviews, and environmental concern) in explaining personal norms, behavioral intentions (i.e., environmental activism), and acceptability of energy policies. Values-especially biosphericappeared to be more powerful in explaining personal norms, intentions, and policy acceptability than were worldviews and environmental concern, although these differences were in some cases not statistically significant.

To change the driving behavior of mail-van driven so as to encourage energy saving, a program was developed and implemented in the Netherlands Postal and Telecommunications Services (FIT). Based on empirical analysis, 3 approaches were used to influence driving behavior: providing information, providing task assignment and control, and providing feedback on gasoline consumption. The effectiveness of the program was tested in a field experiment. Attitudes, social norms, and reported behavior changed, and energy savings of more than 7% were achieved, compared with a control group. From an economic point of view, further implementation in the PTT organization could be attractive.Little is known about the potential for achieving energy conservation through the use of behavioral modifications in industrial organizations. Investigations of energy conservation in

When and why do media-portrayed physically attractive women affect perceivers' self-evaluations? In 6 studies, the authors showed that whether such images affect self-evaluations depends jointly on target features and perceiver features. In Study 1, exposure to a physically attractive target, compared with exposure to an equally attractive model, lowered women's self-evaluations. Study 2 showed that body-dissatisfied women, to a greater extent than body-satisfied women, report that they compare their bodies with other women's bodies. In Study 3, body-dissatisfied women, but not body-satisfied women, were affected by both attractive models and nonmodels. Furthermore, in Study 4, it was body-dissatisfied women, rather than body-satisfied women, who evaluated themselves negatively after exposure to a thin (versus a fat) vase. The authors replicated this result in Study 5 by manipulating, instead of measuring, body dissatisfaction. Finally, Study 6 results suggested that body dissatisfaction increases proneness to social comparison effects because body dissatisfaction increases self-activation.
