Statistical hypothesis testing has been widely criticized by ecologists in recent
years. I review some of the more persistent criticisms of P values and argue that most stem
from misunderstandings or incorrect interpretations, rather than from intrinsic shortcomings
of the P value. I show that P values are intimately linked...
Non-alcoholic Steatohepatitis (NASH) is an emerging form of liver disease associated with obesity, type II diabetes and dyslipidemia. As the prevalence of these metabolic conditions increases, so too has the occurrence of NASH in all sectors of the population. The pathology of this disease is similar to its alcoholic form,...
An exact integral solution for the moisture profile in growing fingers in sandy soil is derived from Richards' equation. The solution provides moisture content along a finger as a function of position and time and provides applicable results, including the calculation of the asymptotic matric potential of a growing finger...
The objective of this thesis is to contribute to the development of p-type materials for transparent electronics applications. Thin films of ®-BaCu2S2, a p-type semi-transparent semiconductor, are fabricated and characterized. ®-BaCu2S2 has a transmittance of 60% to 80 % in the visible portion of the electromagnetic spectrum. The mobility, conductivity,...
To quantify the distribution and abundance of the riparian-associated vertebrate
community, I surveyed streams in four basins in the Oregon Coast Range, 1992-1994. I
observed mostly birds with fewer observations of mammals. Belted Kingfishers (Ceryle
alcyon), American Dippers (Cinclus mexicanus), Great Blue Herons (Ardea herodias),
and Mallards (Anus plalyrhynchos) comprised...
The standard way of representing numbers on computers gives rise to errors
which increase as computations progress. Using p-adic valuations can reduce
error accumulation. Valuation theory tells us that p-adic and standard valuations
cannot be directly compared. The p-adic valuation can, however, be used in
an indirect way. This gives...
Alternative futures studies provide a way for policy-makers and stakeholders to investigate the future impacts of different management strategies by providing representations of possible outcomes. An alternative futures study was undertaken by the Pacific Northwest-Ecosystem Research Consortium for the Willamette River Basin, Oregon, USA, to determine how this regional system...
