THE PERCEPTIONS AND REFLECTIONS ON RACIAL/ETHNICITY DIVERSITY IN OUTDOOR RECREATION.

The collaborative, student-led research team was concerned with race and ethnic diversity in outdoor recreation and explored this issue by interviewing outdoor instructors. Video action research and pedagogy was used based on characteristics of critical thinking, research, reflection, and social justice. The result indicate the disparity of outdoor recreation participation and factors contributing to it.

Futile care policy. Lessons learned from three years' experience in a community hospital.

After reviewing intensive and life supportive care for patients in whom it was probably inappropriate, the hospital bioethics committee established a futile care policy.

Total and high-density lipoprotein cholesterol measurements. Hazards in clinical interpretation.

Duplicate plasma specimens from 24 persons were sent to a community hospital, a commercial laboratory, and a university lipid research laboratory at two separate times to assess the intralaboratory and interlaboratory variations of total and high-density cholesterol measurements. For all three laboratories, the 95% confidence limits for the reproducibility of total cholesterol levels are about +/- 5.5%.
