Uneasy Alliances: Belief And Action On A Geropsychiatric Team, Elizabeth Blesedell Crepeau
Doctoral Dissertations
This ethnographic study explores the influence of two competing ideologies, the medical model and the empowerment model, on the actions of staff on an acute geropsychiatric unit. The medical model emphasizes the professional power of the physician and other health care workers. In contrast the empowerment model emphasizes the autonomy of patients and their role in directing their care. Since these beliefs are contradictory, staff may feel conflict no matter how they act. The tacit nature of these beliefs mask the source of this tension. The mission of the unit is to enhance the independence of people over 60 with …

Macular Pigment In Monozygotic Twins, Billy Randall Hammond
Doctoral Dissertations
Differences in the optical density of macular pigment between ten pairs of identical twins were examined. Foveal and parafoveal sensitivities to lights of 460 and 530 nm were measured by heterochromatic flicker photometry in five separate sessions for the right eye of each twin. These two wavelengths represent the maximum and minimum absorbance for macular pigment. Taking the difference in log sensitivity to the 460 nm light for the fovea and parafovea, after normalizing with respect to 530 nm, yields a measurement of the optical density of macular pigment. Statistically significant differences in macular pigment density were found for five …
