Use of high-strength steel (HSS) reinforcing bars could provide constructability and economic benefits for the construction of structures, reducing the initial and ultimately the life-cycle cost of bridge and building structural elements. This thesis summarizes work performed in a research project on the use of HSS reinforcing bars for concrete...
Net Values is an Environmental Arts & Humanities thesis that centers around a research project of the same name. The research examines individual fishers’ perceptions of adverse economic and social impacts resulting from shifted fishing effort caused by the Oregon Marine Reserves, and looks to understand how fishers use their...
In July of 2001, the Environmental Protection Agency (EPA)
activated the Total Maximum Daily Load (TMDLs) provisions of the
Clean Water Act. As the first river in Oregon to implement TMDL
regulations, people and agencies in the Tualatin basin face many
challenges. Non-point source pollution affects water quality in the...
Attention-deficit/hyperactivity disorder (ADHD), the most common childhood neurological disorder in the United States, also affects grown women. But girls with ADHD, who tend towards symptoms of inattentiveness, often go undiagnosed until young adulthood. This is because (a) their symptoms are less obvious than the hyperactivity common in ADHD boys, and...
Champoeg, located along the Willamette River, developed
as a transportation center for both river and overland
travel and as a shipping point for agricultural products.
Retired employees of the Hudson's Bay Company were the first
to settle in the area, in the 1830s. American settlers
began arriving in large numbers...
Small-scale fisheries often suffer from weak, formal governance, and in response they organize in various ways. These self-organizational arrangements rely on the capacity of informal institutions, such as norms and communication, in generating social cohesion among actors in the supply chain and therefore improve the likelihood of generating commonly devised...

Soil moisture depletion trends under five plant species growing
on the clear-cuts of the Marys Peak Watershed near Corvallis,
Oregon, were followed during the summers of 1963 and 1964. The
species were Holcus lanatus, Lotus crassifolius var. subglaber,
Gaultheria shallon, Berberis nervosa, and Acer circinatum; and
were dominant plants of...
Machine learning has enabled significant advancements in diverse fields, yet, with a few exceptions, has had limited impact on computer architecture. Recent work, however, has begun to explore broader application to design, optimization, and simulation. Notably, machine-learning-based strategies often surpass prior state-of-the-art analytical, heuristic, and human-expert approaches. This thesis first...
I evaluated the response of the federally listed endangered plant species Bradshaw's desert parsley (Lomatium bradshawii) to livestock grazing and small mammal depredation at Oak Creek, Linn County, Oregon, 1997-1998. I established six study blocks (three each in wooded and herbaceous pastures) with plots in each block randomly assigned to...
