ACKNOWLDEGEMENTS
We would like to thank Laura Smith for developing the tables, Geoff Lester and Michael Fisher for draughting the figures, and Randy Pakan for photographing the figures. We are especially grateful for the assistance provided by the respondents to the Edmonton survey and to the students who keenly tabulated the responses. As graduate students, Dia Yiu, Chi Nguyen, and Mark Bourassa made substantial contributions to the analysis of the public survey. They were also co-authors of Charlton et al. (1990). Many individuals mentioned in this study spent a considerable amount of time sharing their insights and searching for materials.
This research was funded by the University of Alberta, the City of Edmonton, the Natural Science and Engineering Research Council of Canada, and Environment Canada.
