Final report for project completed with funding from the Oregon State University Agricultural Research Foundation Continuing Researchers Support Program.
The fish early-life stage (FELS) test (Organisation for Economic Co-operation and Development [OECD] test guideline 210) is the
primary test used internationally to estimate chronic fish toxicity in support of ecological risk assessments and chemical management programs.
As part of an ongoing effort to develop efficient and cost-effective alternatives to...

ANNOTATING ADVERSE OUTCOME PATHWAYS FOR EARLY
FISH DEVELOPMENT

The prevalence of childhood illness requiring hospitalization establishes the need for implementation of an applied intervention to decrease levels of hospitalization-induced anxiety in pediatric patients. In addition to anxiety, levels of perceived trauma have also been linked to pre-operative pediatric patients. Child-Centered Play Therapy (CCPT) within the medical setting has...
This study explored the lived experiences of graduate students in masters-level academic programs who become pregnant, whether intended or otherwise, and the sources from which they received support in their efforts to balance their dual responsibilities as students and mothers-to-be. Through a series of three, semistructured one-on-one interviews, seven participants...
Research universities in the United States recognize the importance of attracting graduate students from around the world to make global collaborations possible and to take advantage of the worldwide demand for higher education. Educational research has developed a large body of literature on the specialized supports that improve successful outcomes...
This thesis proposes an approximate maximum likelihood estimator and
likelihood ratio test for parameters in a generalized linear model when two or
more random effects are present. Substantial progress in parameter estimation
for such models has been made with methods involving generalized least squares
based on the approximate marginal mean...
Triphenylmethyl dye cyanides have been known to be sensitive to ultraviolet radiation since early in this century. Under appropriate conditions, exposure to uv leads to heteropolar fission of the C-CN bond (photoionization) and intense coloration due to dye formation. Thin homogeneous films of hexahydroxyethyl pararosaniline cyanide in a nylon matrix...
The purpose of this dissertation was to demonstrate research scholarship using the American Psychological Association (APA) manuscript-style dissertation format, in accordance with Oregon State University Graduate School and Counseling Academic Unit guidelines. Chapter 1 explains how chapters 2 and 3 are thematically linked manuscripts intended to extend professional literature in...
These studies are part of the Demonstration of Ecosystem Management Options (DEMO) study, a program researching the effects of different levels and patterns of green-tree retention on ecological, economic, and social phenomena. We restricted our studies to the 15% basal area, evenly dispersed retention treatment. Our objectives were, first, to...
Equine-assisted group work has recently emerged in the empirical literature as a promising treatment approach for a variety of populations, including women trauma survivors (Whittlesey-Jermone, 2014; Shambo, Seely, & Vonderfecht, 2010). However, group therapeutic processes (e.g., therapeutic factors) and group leader characteristics have yet to be studied in equine-assisted groups....
The Demonstration of Ecosystem Management Options (DEMO) study is a large-scale, multi-year, interdisciplinary project examining the effects of various levels and patterns of green-tree retention on multiple forest features. Six retention levels and patterns were examined and replicated across six blocks of predominately Douglas-fir forested land in western Oregon and...
The Demonstration for Ecosystem Management Options (DEMO) study originated out of the changing management priorities associated with federal forest lands in the Pacific Northwest which included an objective to maintain mature and old-growth forest characteristics in managed stands. The DEMO project examines the effects that different levels and patterns of...
North American cultivation of Ribes L. may expand as small fruit growers seek species to diversify horticultural crops. The Ribes industry was suppressed for decades out of fear that cultivated black currants and gooseberries would intensify the fungal disease white pine blister rust (WPBR) on five-needle pine (Pinus L. section...
Fava bean is used as a winter or spring cover crop, green manure, silage, forage, hay, and vegetable. It is capable of producing large amounts of dry matter and accumulating large quantities of nitrogen (N), part of which is available to subsequent crops.
Relay strip-cropping combines two vegetation management tactics, under-sowing
and strip-management. In this study conducted from 1994 though 1997, a
cover crop seed-mixture containing oats (Avena sativa L. var. "Monida"), common
vetch (Vicia sativa L.), red clover (Trifolium pratense L.), annual ryegrass (Lolium
multflorum Lam.), and buckwheat (Fagopyrum esculentum Moench) was...
L. C. Dunn (1893-1974) spent most of his scientific career conducting research in
developmental genetics as a member of the Zoology Department at Columbia
University in the City of New York. He had an accomplished scientific career
researching mutations in mice, which earned him respect from other geneticists and
scientists....
In order to examine the potential impact of military jet overflights and other disturbances on productivity of peregrine falcons (Falco peregrinus), we observed behavioral reactions of peregrines to disturbances at nests along the Tanana River, Alaska during the 1995-1997 breeding seasons. Military jets conducted low-altitude flights over a sample of...
Large scale disruption of natural habitats worldwide has led to concern over the
effects of habitat fragmentation on wildlife populations. Small scale experiments may be
a useful tool for discovering effects of fragmentation over larger landscape scales. I
sought to explore the potential for using voles as an experimental model...
