Grizzly bear (Ursus arctos) den-site selection may be influenced by multiple factors at varying spatial extents. To test for hierarchical selection, I compared grizzly bear den sites (n = 21) to random locations in the Southern Lakes, Yukon at two scales: mesoscale (within 1 km of dens) and microscale (within 100 m of dens). I observed selection for den opening slope, pixel slope, soil content, and horizontal cover at the mesoscale. At the microscale, I observed selection for opening slope and horizontal cover. To further test the role of security and the sex hypothesis of sexual segregation, I compared adult female (n = 142), adult male (n = 36), and juvenile (n = 35) den locations in Denali National Park and Preserve, Alaska. Adult females spatially segregated from adult males, with dens characterized by higher elevations and steeper slopes than adult male den sites.

TITLE: ACCEPTABILITY OF INTERVENTIONS OF STAFF IN SHORT TERM CARE SETTING FOR CHILDREN WITH BEHAVIORAL HEALTH ISSUES COMPARING RATING AND HIERARCHICAL SELECTION MAJOR PROFESSOR: Dr. Mark Dixon, Ph.D. The present study asked twenty active treatment team members, in a children’s behavioral health hospital in Springfield, IL to answer a pen and paper survey. This study extended research on treatment acceptability by replicating, Baker and LeBlanc (2011), who compared ratings and hierarchical selections in a long term care facility with older adults. Specifically, participants were given the opportunity to rate treatments using a treatment acceptability survey, and were then given a choice (i.e., asked to select which they would be most comfortable implementing) between various treatment options with using a variety of scenarios and choices. In this study it was interesting to find that though an individual selected a treatment as being a good treatment, when asked what they would feel comfortable using in a pinch did not always match what they related as being acceptable. In comparison the results of Baker and LeBlanc are very similar to the current study. In contrast, the rating for the behavioral intervention was higher in the present study and was also selected much more than in Baker and LeBlanc. Baker and LeBlanc reported statistically significant correlations between selections and ratings. Although this study did not recruit enough participants to allow for a statistical analysis, 50% of the participants in this study had a match for what they rated the highest compared to what they selected the most.
