We extend a Kalman filter model for count data to reflect observations irregularly spaced in time. The model is applied to estimate risk of rare events; bycatch of endangered leatherback turtles in a swordfish fishery off Oregon and California. Incidental takes of turtles are modeled as a Poisson process. The results suggest that take risk is better estimated by regarding the entire history of ...

An experiment was conducted in order to reconstruct previous timbre recognition experiments, measure the effect of ensemble experience and short-term training on the recognition rate, and generate more detailed baseline data to help evaluate the performance of timbre recognition computer models. The subjects, who were conservatory students, had to identify between 2, 3, 9, and 27 instruments on...

Research has consistently shown differences in affect and cognition after exposure to different physical environments. The time course of these emerging or fading during exploration environments is less explored, as most studies measure dependent variables only before environmental exposure. In this within-subject study, we used repeated surveys thought content throughout a 1-h nature conservat...
