A systematic investigation was made of the distribution of short wave radiation within the crown of an open-grown Douglas-fir tree. The study tree was 23 years old, 14 meters tall and had a maximum crown diameter of about ten meters. Global radiation was measured every 15 cm along eight different...
We describe spatio-temporal random processes using linear mixed models and discuss estimation, inference, and prediction under this formulation. We show how many commonly used covariances are special cases of this more general framework and pay special attention to the separable and product-sum covariances. The linear mixed model formulation facilitates straightforward...
The primary purpose of this study was the identification of
specific medicine education learning outcomes which are important
and appropriate for ambulatory, non-institutionalized older adults.
A modification of the Delphi technique was utilized and a panel
of 16 national experts was selected on the basis of four criteria to
respond...
Salmonid B lymphocytes were stimulated both in vivo and in vitro
and shown to produce antibody specific for the immunogen. A passive
hemolytic plaque assay was employed to demonstrate B cells producing
specific antibody. Characterization of plaque forming cells (PFCs)
involved sequential inhibition with a series of graded concentrations
of...
This investigation assessed the effectiveness of an adolescent substance abuse treatment program that incorporated "Rites of Passage." Named Gender Based Treatment (GBT), the treatment program sought to address the adolescents' developmental needs through the use of rituals, myth and story telling, and rites of initiation.
Employing quantitative and qualitative analysis,...
Experimental data on the structural phase changes in zirconia are summarized. The computational techniques of molecular dynamics are reviewed and equations of motion are formulated which allow the study of phase changes as a function of temperature and pressure. The molecular dynamics program NPT which was written for this purpose...
Caenorhabditis elegans is arguably the best understood animal on the planet.
Used for over 50 years to study development, we have a vast amount of knowledge of
the inner workings of this worm. Our knowledge is incomplete, however, without
placing this organism in its evolutionary and ecological context. In this...
As researchers, policymakers and employers begin focusing
on consumer driven health plan models and medical savings
accounts (MSAs), a better understanding of the political
viability of such reform initiatives is necessary. The
purpose of this study was to survey state legislators'
knowledge and perceptions of medical savings accounts
(MSAs) and...
