The forces exerted on light-frame wood buildings as a result of surge and waves are not fully understood. With a better understanding of these types of forces, it may eventually be possible to build coastal structures to better withstand the loads. In this paper, a recent two part experimental study...
This thesis is a study of the changes in the cultural definition of the American Dream. I have chosen to use Superman comics, from 1938 to the present day, as litmus tests for how we have societally interpreted our ideas of “success” and the “American Way.” This work is primarily...
Observations of temperature, winds, and atmospheric trace gases suggest that the transition from troposphere to stratosphere occurs in a layer, rather than at a sharp ‘‘tropopause.’’ In the tropics, this layer is often called the ‘‘tropical tropopause layer’’ (TTL). We present an overview of observations in the TTL and discuss...
The origin of the Pacific Decadal Oscillation (PDO), the leading mode of sea surface temperature variability for the North Pacific, is a matter of considerable debate. One paradigm views the PDO as an independent mode centered in the North Pacific, while another regards it as a largely reddened response to...
This publication is a guide for protecting, conserving, selecting, maintaining, removing, and replacing trees on development sites in the Pacific Northwest. The guidebook is designed to assist people who work with trees during the development and construction phases of both new and existing projects to keep healthy trees a part...
This research effort examined Traditional Ecological Knowledge (TEK) of Siletz tribal members of the environment they live and/or lived in, and how both Western societal beliefs and land reduction to the initially established reservation location affected and altered how the area TEK has been maintained and passed down.

Ocean wave energy is a new and developing field of renewable energy with great potential. The energy contained in one meter of an average wave off the coast of Newport Oregon could supply dozens of homes with electricity. However, ocean waves are usually quite irregular which leads to large bursts...
Measurements of social constructs that evaluate natural hazard preparedness are important to decrease natural hazard vulnerability. Preparedness reduces natural hazard impacts and human vulnerability. Investment in education and education research contribute to human sustainable development and natural hazard preparedness. Faced with other needs, people typically do not prepare enough to...
The results of a machine learning from user behavior can be thought of as a program, and like all programs, it may need to be debugged. Providing ways for the user to debug it matters because without the ability to fix errors, users may find that the learned program’s errors...
In this thesis, I conduct an analysis of paradigmatic background assumptions deployed in engineering decision-making processes, in order to understand how these assumptions, operating tacitly and in tension with each other, contribute to decisions that are ethically less effective and less substantial than they would otherwise be. I do so...
In previous work (Blakemore et al. Org. Lett. 2005, 7, 4721; Heterocycles 2006, 70, 609), successful elaborations of the lupine alkaloids (±)-α-isosparteine (dl-2) and (±)-β-isosparteine (dl-3) were realized from a common tetraoxobispidine precursor, 3,7-diallyl -2,4,6,8-tetraoxo-3,7-diazabicyclo[3.3.1]nonane (93). Herein, the tetraoxobispidine approach to lupine alkaloids was extended to a total synthesis of...
Analysis, visualization, and design of vector fields on surfaces have a wide variety of major applications in both scientific visualization and computer graphics. On the one hand, analysis and visualization of vector fields provide critical insights to the flow data produced from simulation or experiments of various engineering processes. On...
Within this thesis, I posit that poetry, rather than philosophical argument, is a more effective means of expressing and understanding the nature of mystical experiences. William James’ analysis of mysticism inspires the theoretical approach utilized in this thesis. An analysis of the unique qualities of poetic language within mystical discourse...
A poster presentation for the 2009 Annual American Library Conference.
In 2005 Oregon State University librarians set out on a quest to update their pathfinders. Through focus groups and surveys we found that students wanted course-driven guides as well as subject guides. The question then became, how can we enable...
Tissue weighting factors, w[subscript T], used to convert equivalent dose to effective dose, account for differences in radiosensitivity of various organs in the human body and allow users to compare individual organ detriment to whole body risk. They are explicitly calculated in ICRP 26, 60, and 103, although the methods...
The event-scale variability of across-shelf transport was investigated using observations made in 15 m of
water on the central Oregon inner shelf. In a study area with intermittently upwelling-favorable winds and
significant density stratification, hydrographic and velocity observations show rapid across-shelf movement of
water masses over event time scales of...
Multiplicative random cascades (MRCs) can parsimoniously generate highly intermittent patterns similar to those in rainfall. The elemental MRC model parameter is the cascade weight, which determines how rainfall at one scale is partitioned at the next smallest scale in the cascade. While it is known that the probability density of...
ticTOCs, a new journal table of contents service, provides users a free resource for managing RSS feeds for new content from selected journals. This service could be used as a complement and in some cases as an alternative to other table of contents providers. Using RSS feeds provided by publishers,...
The northern California Current System is impacted by two primary freshwater
sources: the Strait of Juan de Fuca and the Columbia River. The Columbia is frequently
bidirectional in summer, with branches both north and south of the river mouth
simultaneously. We describe the interaction of these two warm Columbia plumes...
Contract harvest operations have become the preferred approach to reducing the largest cost component of timber production through free market competition amongst logging contractors bidding or negotiating for work. The goal of this research was to investigate economic components of harvesting operations not previously studied for steep slope thinning harvests...
Researchers have long sought to understand the relationship between economic growth and social development. The notion that economic growth increases social well-being was first written about by Rostow in 1960. This idea quickly became prominent and well accepted- the foundation of development policy. However, in the past twenty years many...
Water temperature is an important measure of water quality, as well as a dominant factor affecting aquatic life within the stream environment. Elevated water temperatures can decrease the survival rate of fish in each life stage. Cold water species, such as salmonids, are particularly susceptible to elevated water temperatures. For...

In 2006, NASA led a field campaign to investigate the factors that control the fate of African easterly waves (AEWs) moving westward into the tropical Atlantic Ocean. Aircraft and surface-based equipment were based on Cape Verde's islands, helping to fill some of the data void between Africa and the Caribbean....
Almost universally, forest inventory and monitoring databases are incomplete, ranging from missing data for only a few records and a few variables, common for small land areas, to missing data for many observations and many variables, common for large land areas. For a wide variety of applications, nearest neighbor (NN)...
The use of paraeducators has increased as a main mechanism to include more
students with disabilities in multiple settings in the public schools in the U.S.
Research has examined the use of paraeducators in typical classroom settings but
little is known about their role in physical education. Although the utilization...
Ecosystems are facing increasing threats from human related activities, such as overfishing, pollution, habitat destruction, species invasions, and diseases, among others. While oceanic islands provide natural laboratories to understand ecological and evolutionary process, they are also particularly vulnerable to these impacts, given their usual isolation from the mainland and the...
Endothelial activation with increased expression of cellular adhesion molecules, chemokines and pro-inflammatory cytokines critically contributes to vascular inflammation and the initiation and progression of atherosclerosis. By affecting redox-sensitive cell signaling pathways and transcription factors, redox-active transition metal ions, such as copper and iron, may play an important role in these...
The purpose of this study is to examine the role of a Filipino American college student organization at a Predominantly White Institution, and uncover elements of the organization that influence or limit the development of critical consciousness of its members. This study focuses on the aspect of critical consciousness that...
Apex predators have experienced catastrophic declines throughout the world as a result of human persecution and habitat loss. These collapses in
top predator populations are commonly associated with dramatic increases in the abundance of smaller predators. Known as “mesopredator release,”
this trophic interaction has been recorded across a range of...
A snowpack model sensitivity study, observed changes of snow cover in the NOAA satellite dataset, and snow cover simulations from the Coupled Model Intercomparison Project phase 3 (CMIP3) multimodel dataset are used to provide new insights into the climate response of Northern Hemisphere (NH) snow cover.

Objective: Millions of US households experienced food insecurity in 2005.
Research indicates that low wages and little social support contribute to food
insecurity. The present study aimed to examine whether social support moderates
the relationship between income and food insecurity.
Design: Using a mail survey, we collected data on social...
This thesis explores the effects study abroad literature, specifically promotional Websites, have on
Oregon State University students when selecting a study abroad program and if the students’ choices reflect
OSU’s International Degree and Education Abroad’s (IDEA) goal of global competency for students.
To explore this, two online surveys were made;...
We studied the feasibility of using end-grain characteristics to match individual boards and cants back to their parent Douglas-fir (Pseudotsuga menziesii) logs. After reviewing marking/reading and biometric automated identification systems, we focused on end-grain biometrics because they appear to have the most promise for sawmills. Biometric identification requires that every...
Decades of experimental work has illustrated the high degree to which the partitioning of most elements is dependent on phase composition, temperature and pressure. In order to quantitatively describe clinopyroxene partitioning it is required to derive expressions using theoretical constraints calibrated with experimental data.
The experimental database available for such...
This thesis is an exploration of Catch-22 (1961) and Slaughterhouse-Five (1969), two early documents of American postmodern literature. In particular, this thesis attempts to present the critical discussions surrounding each novel as parallel to the broader theoretical discussions surrounding the concept of postmodernism. My contention is that, in both of...
The language of water policy both suggests and enforces the relationship that the public should have with water. Differences in language use between policy institutions and the public suggest that the understanding of water promoted through policy may be incongruent with the understanding of water held by the public. Semi-structured...
The purposes of this study were to examine the experiences of African American female students attending urban community colleges, to gain further understanding of how they interpret the meaning of persistence, and to identify the factors that affect their persistence. African American women attending community college in Los Angeles were...
The materiality and neutrality of neutral density and several forms of orthobaric density are calculated and compared using a simple idealization of the warm-sphere water mass properties of the Atlantic Ocean. Materiality is the value of the material derivative, expressed as a quasi-vertical velocity, following the motion of each of...
