Acculturation, defined as the process of adopting the behaviors and beliefs of the dominant host culture, is often associated with dietary change and negative health outcomes, such as increased risk for obesity and diet-related diseases. The large and rising immigrant population in the U.S. necessitates a better understanding of the...
The purpose of this study was to investigate the professional interaction
and interpersonal communication factors in the management of biomedical
instructional development projects which involved the use of electronic media.
Reference is made, repeatedly, in instructional development literature to
the need to include interpersonal communication skills in the education and...
Seeding is a vital tool to facilitate recovery of degraded ecosystems, but low seedling recruitment rates limit the utility of this practice in a range of ecosystems across the globe. Plant functional traits impact individual fitness through effects on growth, reproduction and survival. Consequently, seed and seedling trait variation among...
In 1987, Congress authorized a 5 year $150 million dollar research program called
the Strategic Highway Research Program (SHRP). SHRP was divided into four major

The purpose of this study was to determine the impact a narrative reflecting team experience has on counselor self-efficacy. Through a quasi-experimental design, the use of a narrative reflecting team supervision model was compared to supervision as usual with graduate counseling students (N=12).

Hydrogen is an increasingly attractive low-carbon energy carrier for a variety of stationary and mobile applications. Currently, the vast majority of hydrogen in the United States is produced via the energy intensive steam reforming of natural gas. The cost and carbon emissions associated with hydrogen production can be reduced by...
Approximately 750 million acres, or one-third, of the total area in the United States is in forest land. The United States Forest Service, a 34,000 person agency of the Department of Agriculture, is responsible for the management of roughly 20 percent of the forest land in the United States. The...
Sheep and cattle dietary preferences were determined on tall fescue-subclover ( Festuca arundinacea-Trifolium subterraneum) and
perennial ryegrass-subclover (Lolium perenne-Trifoliuni subterraneum)
pastures in western Oregon during the spring and summer periods
of 1964 and 1965. Esophageal-fistulated Willamette ewes and
Hereford and Hereford-Angus yearling cattle were grazed separately
on each pasture mixture...
We investigated the root endophytic fungi of lupine using
four approaches: (1) occurrence of fungal colonization in field-collected
roots; (2) growth response of L. latifolius to inoculation
with two types of fungi; (3) structure of root colonizations of
Pinus and Lupinus by Phialocephala fortinii, a septate endophytic
fungus of lupine;...
A state of the art motor testing facility has been built at Oregon State University.
This is the largest independent testing laboratory of its type in the western United States.
The construction was funded by a consortium of industrial sponsors, with a goal of
becoming financially self-sufficient by charging the...
We explain a new method of detecting non point source fecal contamination using a PCR based method called Touchdown Polymerase Chain Reaction (TD-PCR). Using genetic markers particular to general, ruminant and human Bacteroides- Prevotella genes, we identified presence in both fresh and salt water environments. Water samples from four sites...
Switched-capacitor (SC) circuits are commonly used for analog signal processing because they can be used to realize precision filters and data converters on an integrated circuit (IC). However, for high speed applications SC circuit operating speeds are limited by the internally-compensated opamps found in SC integrators, a common building block...
A cultivar comparison study was conducted to identify similarities

Population dynamics of coastal cutthroat trout were studied in a controlled-flow section of Berry Creek, Oregon, from August 1972 to August 1973. All trout except the underyearlings were tagged to allow movement, survival and weight change of individual trout to be monitored. Fifty-eight percent of the tagged trout which were...

A recent trend of enhancing freshwater emergent wetlands for waterfowl and other wildlife has raised concern about the effects of such measures on juvenile salmonids. We undertook this study to quantify the degree and extent of juvenile Pacific salmon Oncorhynchus spp. utilization of enhanced and unenhanced emergent wetlands within the...
Different educational modalities can affect students in learning challenging engineering concepts. Studies that specifically measure students’ conceptual learning gains have been conducted in face-to-face (F2F) and online modalities, but few direct comparisons have been reported. In this study, we collected data from undergraduate students enrolled in introductory materials science courses...

Adolescent substance use is a developmentally contingent social practice that is constituted within the routine social-environment of adolescents' lives.

1. Multidimensional trait frameworks are increasingly used to understand plant strategies for growth and survival. However, it is unclear if frameworks developed at a global level can be applied in local communities and how well these frameworks—based largely on plant morphological traits—align with plant physiology and response to stress.

During 2016-2018, unprecedented aggregations of the colonial pelagic tunicate Pyrosoma atlanticum were observed in the Northern California Current (NCC). Pyrosomes are common in tropical and sub-tropical ocean waters, but little is known about their abundance, distribution, and trophic ecology in mid-latitude systems. To assess these factors, pyrosomes were collected during...
Fish monitoring programs often rely on the collection, species identification, and counting of individual fish over time to inform natural resource management decisions. Thus, the utility of the data used to inform these decisions can be negatively affected by species misidentification. Fish species misidentification bias can be minimized by confirming...
