coefficient and "true" consumer surplus. Each method was
ranked, using the root mean squared error (RMSE)...
A number of thinkers are becoming increasingly persuaded
that our anthropocentric view of nature is inadequate, that we
need a "new morality" with regard to the environment. In this
essay, I argue that an alternative to anthropocentricism is
available to us now-and has been since at least 1836. I look...
Cover-projection models were developed based on algebraic difference formulations of an exponential-power function to describe shrub recovery and development patterns after clear-cutting and site preparation. We tested the effect of six treatments on shrub growth patterns by incorporating indicator variables into the rate and shape parameters of the models for...
