Relevant theoretical frameworks for understanding environmental conflict resolution (ECR) collaborative processes and stakeholder partnership success are reviewed from political science, sociology, alternative dispute resolution (ADR), and systems engineering. The chapter provides an overview of existing and emerging models, techniques, and governance institutions for implementing public involvement processes (e.g., policy dialogues, collaborative learning). Conceptual progress in developing evaluation criteria for assessment of these collaborative processes and programs is summarized, followed by a narrative review of relevant empirical evaluation studies. The chapter concludes with commentary on prevailing trends in the literature and promising directions for future research.

The model proposes that members of groups sharing resources first anchor their consumption choices on an "equal-division" heuristic and then, given sufficient cognitive capacity, adjust their choices in a self-serving direction. The results from both studies support the model. The first study found that when faced with a common resource pool almost all group members expressed thoughts regarding equality; however, individuals with sufficient cognitive capacity requested more from the pool and expressed more task-relevant thoughts than individuals lacking the necessary cognitive resources. The second study provided additional support for the two-stage model by demonstrating that group members' cognitions occur in the order predicted by the model and by demonstrating that an individual difference, social value orientation, affects thought proc-

To begin to address this problem, we examined the effects of hurricane track and intensity information in a laboratory setting where participants judged the probability that hypothetical hurricanes with a constant bearing (i.e., straight line forecast track) would make landfall in each of eight 45 degree sectors around the Gulf of Mexico. The results from 162 participants in a student sample showed that the judged strike probability distributions over the eight sectors within each scenario were, unsurprisingly, unimodal and centered on the sector toward which the forecast track pointed. More significantly, although strike probability judgments for the sector in the direction of the forecast track were generally higher than the corresponding judgments for the other sectors, the latter were not zero. Most significantly, there were no appreciable differences in the patterns of strike probability judgments for hurricane tracks represented by a forecast track only, an uncertainty cone only, or forecast track with an uncertainty cone-a result consistent with a recent survey of coastal residents threatened by Hurricane Charley. The study results suggest that people are able to correctly process basic information about hurricane tracks but they do make some errors. More research is needed to understand the sources of these errors and to identify better methods of displaying uncertainty about hurricane parameters.

The study examined 110 Boston residents' and 203 Texas students' expectations of getting sick through different exposure paths for contact with contaminated water. In addition, the study assessed respondents' actual implementation (for residents) or behavioral expectations (for students) of three different protective actions - bottled water, boiled water, and personally chlorinated water - as well as their demographic characteristics and previous experience with water contamination. The results indicate that people distinguish among the exposure paths, but the differences are small (one-third to one-half of the response scale). Nonetheless, the perceived risk from the exposure paths helps to explain why people are expected to consume (or actually consumed) bottled water rather than boiled or personally chlorinated water. Overall, these results indicate that local authorities should take care to communicate the relative risks of different exposure paths and should expect that people will respond to a boil water order primarily by consuming bottled water. Thus, they should make special efforts to increase supplies of bottled water in their communities during water contamination emergencies.

Several causal explanations (i.e., group identity, commitment-making, norms) have been proposed and tested experimentally. This chapter reviews the literature on group discussion and cooperation to further explore why and how face-to-face discussion exerts this robust effect. We also extend the current conversation by considering whether various forms of electronic technology (e.g., e-mail, Internet conferencing) allow small groups to capture the proven benefits of discussion without the limiting requirement of collocation. Our literature review and conceptual analysis suggest some important theoretical implications for understanding discussion's effect in social dilemmas and a promising agenda for future research.
