The history of American Indian and Alaska Natives (AIAN) in education is filled with conflict and painful memories for many. Indian boarding schools that lasted through the early 1900s were used as a tool for forced assimilation of AIAN people. With the disturbing motto of “Kill the Indian, save the...
An algorithm is described for determining the vertices
and supporting planes (or lines) of the convex hull
of a given set of N distinct points in 3-space. The
method involves determining a finite sequence of convex
hulls, each successive convex hull being a better approximation
to the convex hull of...
The effects of beaver (Castor canadensis) on stream morphology, riparian zones, and coho salmon (Oncorhynchus kisutch) fry in Cape and Cummins Creeks, Oregon, were examined using stream surveys, vegetation transects, and coho salmon fry counts in 1987. The basin around Cape Creek has been extensively logged since the late 1940's....
Optimal aging is strongly related to personality factors along with health-behavior habits.

Optimal aging is strongly related to personality factors along with health
Caregiving circumstances frequently evoke high levels of stress for caregivers and have consistently been linked to adverse psychological and physical health consequences. Within the caregiving literature, researchers have sought to answer questions about why some individuals seem to be particularly vulnerable to the well-established deleterious consequences of caregiving stress. Several...
This work was performed on Trillium albidum Freeman (Liliaceae), to
clarify the pattern of morphological variation between the small-flowered
populations at the northern limit of its range ( T. parviflorum Soukup) and the
larger-flowered populations from southern Oregon and northern California. It was
hypothesized that only a single species of...
Produced water is a highly saline waste product of oil and gas production, which is generated in larger volumes than the hydrocarbons themselves in the United States. Spillage of produced water is of concern because its high salinity can contaminate soil, surface water and groundwater resources, and kill vegetation, including...
Driving simulation is widely accepted as a safe, effective, and economical alternative for investigating driver behavior in a variety of contexts. However, in order to apply simulator-based research results to real-world settings, the performance measures acquired through simulated driving experiments must first be validated. This research was aimed at validating...
Incidental bycatch in commercial fisheries has been identified as a threat to black-footed albatrosses (Phoebastria nigripes) and Laysan albatrosses (P. immutabilis). Effective long-term conservation of these albatrosses necessitates a thorough understanding of their marine distribution, which marine habitats are selected during foraging, and where they are most likely to interact...
The purpose of this study was to better understand the relationship between selected academic factors and the persistence of GED recipients in community colleges in the state of Oregon. With this purpose in mind, the study addressed the following research question: Is there a relationship between selected academic variables and...
The study was undertaken to determine if the construct and vocabulary
of systems theory are related to academic performance such that
a) the understanding of either or both can predict grade-point average
for college students, and b) the explicit teaching of both construct
and vocabulary to minority students can improve...
With an estimated 5.4 million Americans living with Alzheimer’s disease facing
individual, social, and financial burdens, researchers must make cognitive assessment inquiries a priority (Alzheimer’s Association, 2016). Cognition encompasses multiple aspects of thought
processes, such as multiple types of memory, planning, inhibitory control, attention, and
processing speed. The higher level...
The rural two-lane highway in the southeastern United States is frequently associated with a disproportionate number of serious and fatal crashes. The major research objectives are to investigate the relations between probabilities of fatal crash type occurrence and potential contributing factors from road geometric design characteristics and roadside, environmental features....
Chemoreception is one of the dominant sensory modalities for many species of salamanders (reviewed in Chapter 2). At least seven of the ten currently recognized salamander families are known to respond to some sort of chemical cue. These responses are as varied as delaying hatching, seeking refuge, or initiating aggressive...
Solid-state esophageal manometry was used to study physiology of the normal llama esophagus. Esophageal baseline pressures, esophageal response to water swallows and to balloon distention, and other motor activity of the esophagus during experiments were measured throughout the entire length of the esophagus. Gross and histologic anatomy, muscle fiber type...
The Supreme Court Bar-the lawyers who argue before the US Supreme Court-has historically been an elite and exclusive group. This investigation examines the demographic make-up of the Supreme Court Bar in the Roberts Court and compares it to previous iterations of the Supreme Court Bar, as well as the national...
An estimated 5.7 million Americans are currently living with the dementia stage of Alzheimer’s disease, impeding health and wellbeing for individuals diagnosed, caregivers, families, and communities across the country (Alzheimer’s Association, 2018). Studying early indicators of age-related cognitive decline and pathological cognitive impairment (e.g., Alzheimer’s disease) is crucial to inform...
Research indicates that adolescents with a history of parental incarceration are at higher risk of delinquent behaviors (Murray & Farrington, 2005), however the protective role of parent-adolescent relationships is largely unexamined when compared with negative dimensions of parenting. To examine the potential protective effects of the adolescent’s perceptions of a...
Each year an estimated one million young women in the United States develop an eating disorder. Without early recognition of symptoms and early intervention/treatment, these eating disorders can lead to a host of chronic and debilitating illnesses.
Tooth erosion is one of the first signs of an eating disorder, providing...
Documentation of the side effects of pesticides on
arthropod natural enemies has expanded rapidly since the
1950's as part of an increase in non-target side effects
literature. Most reviews have been based on empirical
analysis of selected literature. The SELCTV database was
developed to make a larger information base accessible...
Pea seed-borne mosaic potyvirus pathotype 1 (PSbMV-P1) has the ability to infect most genotypes of Pisum sativum. The exception are those genotypes that are homozygous recessive for the sbm-1 gene. The life cycle of PSbMV pathotype 4 (PSbMV-P4) is unaffected by the sbm-1/sbm-1 genotype. Infectious clones of Pl-P4 recombinants were...
Mentor teachers are currently seen as a solution to
education's dilemma of how to orient beginners into the
profession and provide educational advancement for its most
capable, experienced teachers. One goal of Oregon's mentor
program is to have mentors provide their proteges with
instructional assistance through an observation process.
The...
Groundwater is a vital resource and efforts must be made to protect its quality. In certain areas, its quality has been
threatened by the introduction of oil and gasoline, many times originating from underground storage tanks. Massachusetts has
directly reacted to this concern about groundwater quality by promulating a Massachusetts...
Sustaining an older adult's ability to live independently is a very important
goal of geriatrics and gerontology. The extent to which an individual can live
independently depends on his or her ability to perform Instrumental Activities of Daily
Living. Impairments in the physical domains of muscle strength, flexibility,
endurance, and...
Interviewing eighteen older parents (aged 65 and older) with two or more children for this project established support for the emotional experience of intergenerational ambivalence. Seventy-five parent-child relationships were discussed. Two major themes arose over what healthy, independently living parents feel ambivalent about in their relationships with their midlife children....
Grounded in life span theory, this study explored how personal goals (as measured by possible selves) related to depressive symptoms in older adults. Possible selves represent individuals' ideas of what they would like to become (hoped-for selves) and what they are afraid of becoming (feared selves). Possible selves are also...
Isolated approaches at signalized intersections with posted speed limits of 45 mph or greater generally experience large numbers of rear-end and angle collisions. A combination of less attentive drivers, high operating speeds, and less than ideal intersection characteristics can result in crash frequencies well above expected rates. A number of...
Posting advisory speed signs at sharp horizontal curve sites is a practice well established in the United States. The purpose of these signs is to provide the driving public with a safe speed to negotiate such curves; however, the link between these signs and safety has not yet been clearly...
An ability to meet the changing demands associated with development
promotes purpose in life, a defining feature of psychological well-being. Midlife
adults consistently report higher purpose in life compared to older adults. However,
less is known about the dynamics of purpose in life in the transition from middle to
older...
The purpose of this qualitative study was to examine the experience of white principals in understanding their white identity, privilege, and power as they worked to implement socially-just and culturally proficient schools. The findings offer insights into the following questions: 1) How do white school leaders view white identity and...
The purpose of this case study was to examine a third-grade teacher’s effective use of mathematical discourse in the classroom setting. The study offers insights into the following research questions: 1) How does a teacher’s engagement in mathematical discourse communities influence her practice and self-efficacy as a mathematics educator? 2)...
The complexity of numerical ocean circulation models requires careful checking with a variety of test problems. The purpose of this paper is to develop a test problem involving Rossby and gravity waves in a two-layer fluid in a channel. The goal is to compute very accurate solutions to this test...
Understanding the dynamics of open marine populations is difficult. Ecological processes may vary with the spatial structure of the habitat, and this variation may subsequently affect demographic rates. In a series of observational and experimental studies in the Bahamas, I examined the roles of emigration, mortality, and predation in the...
The emergence of high explosives on the battlefield can be defined both literally and figuratively as a seismic event in the landscape of modern warfare. High explosives first came into common use in war in 1914. By the end of World War I just four years later, more than 2.5...

Rare plant reintroductions are a critical conservation tool for the augmentation of diminishing populations, or re-establishment of extirpated populations. Analysis of reintroduction failures suggests that a sophisticated understanding of species biology, ecology, and habitat is essential for producing self-sustaining rare plant populations. This study sought to generate that background knowledge...
In this study, we explored the relationships among gender, age, daily stressors, positive and negative affect, and neuroticism on cortisol outcomes in older men and women. We were particularly interested in whether variation in positive affect would have an effect on variation in negative affect and if this relationship would...
Dual Language Learners (DLLs) represent a substantial subpopulation in United States preschool programs (Aikens, Kinas, Malone, Tarullo, & Harding, 2017). DLLs often come from low socio-economic backgrounds and encounter barriers to academic success (National Academies of Science, 2017; Thomas & Collier, 2002). One consistent predictor of academic success is executive...

This study examined four occupational health risks that contribute to job strain, the experience of infectious disease, musculoskeletal strain, job dissatisfaction, and depressive symptoms, for toddler teachers as predictors of classroom quality. Both the physical and social settings of early care and education (ECE) are influential in shaping children’s early...
An approach to climate change feedback analysis is described in which tropospheric relative humidity replaces specific humidity as the state variable that, along with the temperature structure, surface albedos, and clouds, controls the magnitude of the response of global mean surface temperature to a radiative forcing. Despite being simply a...
Posting advisory speed signs at sharp horizontal curves to provide the driving public with a safe speed is a practice well established in the United States. The operational effectiveness of these signs has long been questioned in the current literature. The authors of this paper recently developed a function to...
This dissertation expands the theory of subjectivity by examining how discourses
behave. Of particular intent here is the subjectivity of preservice teachers. Students from
Oregon State University's Masters of Arts in Teaching program volunteered as
participants. Audio-taped sessions of their small group talk about gender issues and
education, dialogue journals,...
Measurements of stratospheric water vapor by the Microwave Limb Sounder aboard the Upper Atmosphere Research Satellite show that in the tropical lower stratosphere, low‐frequency variations are closely related to the annual cycle in tropical tropopause temperatures. Tropical stratospheric air appears to retain information about the tropopause conditions it encountered for...
Erigeron decumbens var. decumbens, the Willamette daisy, is known only from the Willamette Valley of Oregon. Herbarium records, from the 1800's until 1934, indicate that the Willamette daisy was once common and widely distributed throughout the Willamette Valley (Clark et al. 1993). However, between 1934 and 1980, this taxon was...
Some argumentation texts require additional evidentiary support to uphold their ethical propositions. A rhetorical critique of eight argumentation textbooks for ethical propositions and corresponding support, reason and evidentiary materials reveals that some texts advance ethical claims without providing sufficient backing. Inadequate support for an ethical proposition decreases the likelihood of...
On the surface, the written works of the Marquis de Sade appear to be nothing more than pornographic mania articulated, the narrative trajectory of which oscillates between illicit words and acts. Yet his life and works are important to historians, if not due to their inherent quality then because they...
