Understanding connectivity among exploited populations is critical to their sustainable management and long-term viability. In the marine environment, estimates of connectivity often rely on the use of genetic markers, as dispersal primarily occurs during a planktonic larval phase which is difficult to track using direct methods. In this thesis, we...
The United States is becoming a service oriented nation. As
increasing amounts of the gross national product are spent on services,
it becomes vitally important to ensure the productivity of these
services. The purpose of this thesis is to identify which elements are
needed in a service department productivity measurement...
Blackberries, genus Rubus, are an important Oregon agricultural commodity. In their fresh and processed forms, they offer many health benefits and may be able to help Americans better achieve fruit consumption recommendations because of convenience and pleasant sensory qualities. However, the susceptibility of blackberry products to contamination with bacterial pathogens...
A study was conducted using data collected from a sample of mint and
vegetable farmers in the Willamette Valley of Oregon. The study identifies the
influence of demographic differences, economic factors and irrigator attitudes on
irrigation efficiency.
Only two of the 19 characteristics theorized to influence irrigation
efficiency proved to...
If two dams on the Elwha River are removed, the ecosystem will be open to the downstream flow of sediments and the upstream flow of marine nutrients in the form of anadromous fish. Nutrient enrichment may influence trophic dynamics of the entire ecosystem, extending beyond the aquatic boundary. I assessed...
Clashes of ideology are all around us, from our computer and television screens to our composition classrooms, and they merit attention within the composition classroom. This thesis examines the justifications and pedagogies that scholars in rhetoric and composition use to infuse issues of ideology and social ethics into writing instruction...

Determination of the Vertebrate pedigree was a
particularly enigmatic problem for evolutionary morphologists
of the early post-Darwinian period. At that time,
practically no characteristics were known by which the
Vertebrates could be linked to any of the other animal
groups. Up to the 1850's, most research in embryology
and anatomy...
