This study was conducted at portions of Trap Bay Creek, a medium-sized third-order stream on Chichagof Island, Southeast Alaska, to
1) quantify short-term sediment transport and channel morphology changes, 2) relate measured sediment transport rates to the major hydrologic parameters that appeared to determine the mechanisms of sediment transport, and...
This thesis consists of five chapters: a general introduction, two manuscripts, a collection of published lesson plans, and a general conclusion. The works collected herein are united by the common theme of practical applications in plant breeding. The first manuscript reports a study performed on five malting barley lines grown...
Addiction is a word that represents a condition that, at best, causes minor disruptions to one’s life and, at worst, is lethal. The current definition was developed by 80 neuroscientists. It references substance use and other behaviors and includes food and sex. Addictions do not seem to be lessening but...
Needle length in young ponderosa pine (Pinus ponderosa Dougl. ex Laws var. ponderosa) was assessed for its ability to estimate site quality of afforested land in Neuquén, Argentina. The objective was to determine the best aspect on the tree, number of needle age classes, and number of trees that would...
This study determined the importance of specific research tasks to the present job requirements of State Department of Education professionals, college and university instructional faculty, and secondary school counselors in Oregon. The instrument utilized in the research was designed and validated through a Delphi process. The computed reliability coefficient was...
The abundance and biomass of cutthroat trout (Salmo clarki) have
been found to be greater in logged than in forested streams of the
Oregon Cascades. Although certain prey taxa increase in abundance
following logging, habitat stability generally decreases and cover
structures are removed. Research was conducted to examine the manner...
Prevention of groundwater contamination by agricultural
chemicals requires an understanding of the complex
processes that control pesticide movement below the soil
surface. Through this understanding it is possible to try
to predict which areas may be most vulnerable to
contamination. The many models that have been developed to
characterize pesticide...
The purpose of this study was to compare the delinquent behavior, psychological
health, and emotional wellbeing of maltreated and nonmaltreated adolescents in a
chemical dependency treatment program. Data were collected over a seven year period
from intake interviews and Minnesota Multiphasic Personality Inventory (MMPI) scores
of 522 adolescent patients at...
Water is one of the most interdisciplinary topics in natural resources librarianship. At OSU we not only support the growing Water Resources Graduate Program (in which faculty from six colleges and Extension participate), but a search of our library catalog for "water"-related theses and dissertations reveals that disciplines as diverse...

Simple parameterizations of dune erosion are necessary for forecasting erosion potential prior to an oncoming storm. Dune erosion may be parameterized in terms of the elevation of the total water level (composed of surge, tide, and wave runup) above the dune base and period of exposure of the dune to...
To measure organismal coherence in a pelagic ecosystem, we used moored sensors to describe the vertical dynamics of each step in the food chain in shelf waters off the west shore of Oahu, Hawaii. Horizontally extensive, intense aggregations of phytoplankton, zooplankton, and micronekton exhibited strong diel patterns in abundance and...
The extensive literature in biomedical ethics on physician-assisted death has represented the debate to involve three parties with significant interests. First, there are arguments regarding the legitimacy of terminally patients seeking to exercise an expanded right of self-determination. Furthermore, questions have been posed regarding the compatibility of a patient request...
The importance of spatial pattern in ecosystems has long been recognized. However, incorporating patchiness into our understanding of forces regulating ecosystems has proven challenging. We used a combination of continuously sampling moored sensors complemented by shipboard sampling to measure the temporal variation, abundance, and vertical distribution of four trophic levels...
The authors employ a social-ecological framework to aid our understanding of the complex array of factors in the immediate and broader environment that influence adolescent sexual development. Further, sexual development is viewed as normative and critical to positive growth. The authors provide an overview of the
Two-Cities Study, a multi-stage...
We consider an SI model of three competing species that are all affected by a single pathogen which is transmitted directly via mass action. The total population sizes of the three species satisfy a three-dimensional Lotka-Volterra competition model. We address the interaction between competition and disease dynamics, and show that...
