CONCLUSIONS Many issues and questions must be addressed in future research on attitudes in social behavior. One important issue is the internal structure of attitudes, including the dimensionality of attitudes and the conditions under which different components of attitudes are more in uential than are other components. A related issue is the distinction between implicit attitudes and explicit attitudes (or between implicit and explicit measures of attitudes), including the question of which sorts of behavior are best predicted by each type of attitude (measure). The connections between attitudes and broader constructs like values and ideologies also need to be clari ed. Turning to a different domain, the role of biological factors in attitude formation and change seems likely to receive more attention over the next decade. Finally, the connection between attitudes and behavior will continue to interest social psychologists, with models of attitude-behavior consistency becoming increasingly complex. For example, prediction may be improved by simultaneously taking into account attitudes toward all of the different behavioral options in a setting. In closing, the evidence described in this chapter supports the importance of the construct of attitude. Because of their broad evaluative nature, attitudes may potentially re ect diverse beliefs, feelings, and behaviors. In addition, these evaluations serve a number of attitude functions and vary on several characteristics (e.g., ambivalence, certainty). Most important is that attitudes in uence a wide variety of important social behaviors. Indeed, no matter what the setting, personal evaluations play a role in information processing and in behavior.

Transient time-dependent solutions for diffusion to a droplet radius R (e.g. [1]) exist to this equation with a timescale D = R 2 /D = 10 7 R( m)2 s (3.18) for D = 10 5 m2 s 1 . These timescales are much shorter than time changes relevant to aerosols in environmental atmospheric situations, so that it is always justi ed to use quasi-stationary solutions to Equation (3.17), which nevertheless can refer to concentrations at boundaries that are time dependent on a much longer timescale. Then we can take c/ t = 0 and obtain the original solution of Maxwell [13] to the equation, with c depending on 1/r and a constant total molecular mass current to the droplet of J D = 4 mDr 2 dc /dr = 4 mD R[c ( ) c (R)] (3.19)
