Effect of imperfect detectability on adaptive and conventional sampling: simulated sampling of freshwater mussels in the upper Mississippi River.

Adaptive sampling designs are recommended where, as is typical with freshwater mussels, the outcome of interest is rare and clustered. However, the performance of adaptive designs has not been investigated when outcomes are not only rare and clustered but also imperfectly detected. We address this combination of challenges using data simulated to mimic properties of freshwater mussels from a reach of the upper Mississippi River.

Fostering independence in health-promoting exercise.

The Integrated Model of Physical Activity and Disability was used to design a strength and aerobic exercise program for adults with intellectual disability participating in Special Olympics. This study examined the extent to which four participants could acquire exercise skills in a face-to-face context and apply these skills at home with indirect support. Adherence to the program, as well as program satisfaction, was examined.
