Background: The critical importance of improving the well-being of people with disabilities is highlighted in many national health plans. Self-reported health status is reduced both with age and among people with disabilities. Because both factors are related to health status and the influence of the age at disability onset on...
I argue that Matthew’s seven acts of corporal mercies provide a means of reading Piers Plowman within a framework familiar to medieval audiences, but also exposes the different models of health that are at work within the poem and the soteriological significance of these healths. In chapter one, I focus...
This study frames the problem of needing to better understand retention patterns in Alaska among students from distinct levels of rurality and how those levels of rurality or geographical distance may interact with other variables including race and gender in predicting student retention. Alaska is a highly rural state with...
This thesis examines the concepts of power and participation and how they are intertwined in the examination of the urban planning systems in Curitiba, Brazil. Power is identified as both the planning system's ability to affect the daily lives of the city's residents and the power of individuals and groups...
Long-term data sets that quantitatively confirm basic ecological theory are rare for field
populations. Highly variable recruitment often causes wide temporal variation in population
age distribution and basic theory for adaptive sex ratio often predicts ‘sex ratio tracking’ to
match the fluctuating age distribution. Using sex-changing shrimp as a model...
The effects of exotic species invasions on biodiversity vary with spatial scale, and documentation of local-scale changes in biodiversity following invasion is generally lacking. Coupling long-term observations of local community dynamics with experiments to determine the role played by exotic species in recruitment limitation of native species would inform both...
A three-dimensional large-eddy simulation (LES) model was used to examine how stratified flow interacts with bottom obstacles in the coastal ocean. Bottom terrain representing a 2D ridge was modeled using a finite-volume approach with ridge height (4.5 m) and width (~30 m) and water depth (~45 m) appropriate for coastal...
The western slope of the Oregon Cascades receives up to 3500 mm of precipitation annually, with a majority falling between the months of November-March. In this maritime climate, the partitioning of precipitation between rain and snow is highly sensitive to temperature. Climate models generally agree that winter temperatures in the...
The importance of leads, sea ice motion, and frazil ice on the wintertime ocean
Boundary layer was examined by using a large-eddy simulation turbulence model coupled to a
thermodynamic slab ice model. Coupling was achieved through exchange coefficients that
accounted for the differing diffusion rates of heat and salinity. Frazil...
