Catholic Action In Twentieth-Century Oregon: The Divergent Political And Social Philosophies Of Hall S. Lusk And Francis J. Murnane, Ian Alan Berge

Dissertations and Theses

Catholic Action was an international movement that encouraged active promotion of the Catholic faith by ordinary believers. While the idea gained force at a local level in Italy in the early twentieth century, Pope Pius XI gave the philosophy official Church approval in 1931. Catholic Action served as a major intellectual and religious force among American Catholics from the Great Depression until the transformations in Catholicism caused by the Second Vatican Council from 1962 to 1965. The program encouraged American Catholics both to promote the practice of the faith among fellow Church members and to express Catholic teachings in the …

Nonlinear Analysis And Digital Pre-Distortion Of The Sc-Fdma Signals In Lte Uplink System, Changwen Zhu

Dissertations and Theses

Single-carrier frequency division multiple access (SC-FDMA) has become a popular alternative to orthogonal frequency division multiple access (OFDM) in multi-user communication on LTE uplink systems. This is primarily due to the low peak-to-average power ratio (PAPR) of SC-FDMA compared to that of OFDM. Long-term evolution (LTE) uses SC-FDMA on the uplink to exploit this PAPR advantage to reduce transmit power amplifier (PA) back-off in mobile user terminals. However, the latest generation of communication systems requires high power efficiency and a large quantity of capacity in transmitting mobile data, bringing out some other critical problems: 1) the nonlinearity of Radio Frequency …

Optimizing Data Movement In Hybrid Analytic Systems, Patrick Michael Leyshock

Dissertations and Theses

Hybrid systems for analyzing big data integrate an analytic tool and a dedicated data-management platform, storing data and operating on the data at both components. While hybrid systems have benefits over alternative architectures, in order to be effective, data movement between the two hybrid components must be minimized. Extant hybrid systems either fail to address performance problems stemming from inter-component data movement, or else require the user to explicitly reason about and manage data movement. My work presents the design, implementation, and evaluation of a hybrid analytic system for array-structured data that automatically minimizes data movement between the hybrid components. …

Synthesis Of Irreversible Incompletely Specified Multi-Output Functions To Reversible Eosops Circuits With Pse Gates, Robert Adrian Fiszer

Dissertations and Theses

As quantum computers edge closer to viability, it becomes necessary to create logic synthesis and minimization algorithms that take into account the particular aspects of quantum computers that differentiate them from classical computers. Since quantum computers can be functionally described as reversible computers with superposition and entanglement, both advances in reversible synthesis and increased utilization of superposition and entanglement in quantum algorithms will increase the power of quantum computing.

One necessary component of any practical quantum computer is the computation of irreversible functions. However, very little work has been done on algorithms that synthesize and minimize irreversible functions into a …

Style Shifting In First-Encounter Conversations Between Japanese Speakers, Kenichi Shinkuma

Dissertations and Theses

This study examines style shift between formal and informal styles in first- encounter conversations between Japanese native speakers and demonstrates how the speakers shifted the speech style in the context. Many researchers have studied this type of style shift and demonstrated that style shifts occur within a single speech context where social factors, such as differences in age, status, and formalness remain constant (e.g., Cook, 2008; Geyer, 2008; Ikuta, 1983; Maynard, 1991; Okamoto, 1999). This study contributed support to these previous studies. In this study, both quantitative and qualitative analyses focusing on Japanese native speakers' use of style shifting in …

The Nax Language: Unifying Functional Programming And Logical Reasoning In A Language Based On Mendler-Style Recursion Schemes And Term-Indexed Types, Ki Yung Ahn

Dissertations and Theses

Two major applications of lambda calculi in computer science are functional programming languages and mechanized reasoning systems (or, proof assistants). According to the Curry--Howard correspondence, it is possible, in principle, to design a unified language based on a typed lambda calculus for both logical reasoning and programming. However, the different requirements of programming languages and reasoning systems make it difficult to design such a unified language that provides both. Programming languages usually extend lambda calculi with programming-friendly features (e.g., recursive datatypes, general recursion) for supporting the flexibility to model various computations, while sacrificing logical consistency. Logical reasoning systems usually extend …

Language Skill Development In Japanese Kokugo Education: Analysis Of The Television Program Wakaru Kokugo Yomikaki No Tsubo, Ruri Yoshii

Dissertations and Theses

Any type of education implemented by a modern nation-state is, at least in part, a tool for socializing its people. In this regard, Japanese language and literature education, kokugo, has played an important role in Japan by emphasizing nationalism and the integrity of a Japanese identity. According to Ishihara (2007) and Lee (1996 [English translation 2010]), kokugo, since its inception in 1900, has promoted moral awareness and assimilation of Japanese ideals across the country. However, responding to unsatisfactory test results in the Program for International Student Assessment (PISA) in 2003 and 2006, Japan's Ministry of Education Culture, Sports, Science and …

The Impact Of Documentation Status On The Educational Attainment Experiences Of Undocumented Hispanic/Latino Students, Brittanie Alexandria Roberts

Dissertations and Theses

The issue of undocumented immigration has recently taken center-stage in the media and national politics in the United States. A large population of undocumented youth grows up with legal access to public education through high school, following the Supreme Court decision of Plyler vs. Doe, but faces legal and economic barriers to post-secondary education. Following high school, undocumented Hispanic/Latino youth legal protections end, greatly limiting chances for upward mobility through traditional post-secondary education pipelines. In some cases, knowledge of future barriers to post-secondary education leads to a decline in educational motivation.

The current political atmosphere makes this study a bit …

Elaborating Patient Agency In Breast-Cancer Care: A Grounded Theoretical Analysis Of Patients Asserting Treatment Preferences, Rachel Sofia Erdman

Dissertations and Theses

Successful physician-patient communication is increasingly being acknowledged as a vital aspect of healthcare today. Research in the field has not examined all aspects of patient-centered care and the aspects that have been studied have not been grounded in actual patient action. The research done in the field has largely been studied quantitatively. The present thesis research attempts to contribute to the gap in the field of physician-patient communication by qualitatively examining patient assertiveness. This thesis examines conversations between women in Portland, Oregon recently diagnosed with breast cancer talking to their surgeons about their diagnoses and treatment options. Using grounded qualitative …

Applications Of Remote Sensing To The Study Of Estuarine Physics: Suspended Sediment Dynamics In The Columbia River Estuary, Austin Scott Hudson

Dissertations and Theses

Estuarine circulation and its associated transport processes drive the environmental integrity of many near-shore habitats (the coastal ocean, rivers, estuaries and emergent wetlands). A thorough understanding and consideration of this circulation is, therefore, vital in the proper management of these habitats. The aim of this study is to bring together theory and new satellite observations in the Columbia River Estuary to increase our understanding of estuarine circulation and transport. Surface reflectance measurements gathered by the Moderate Imaging Spectroradiometer (MODIS) are first compared to in situ observations to develop an empirical model for remotely derived surface turbidity. Results indicate that MODIS …

Strengths In Action: Implementing A Learning Organization Model In A Human Service Setting, Barbara Ann Whitbeck

Dissertations and Theses

Although learning organization theory evolved in corporate settings, literature suggests that the theory has much to offer human service organizations. This dissertation examines the implementation of a modified learning organization model in three small field offices of a publicly-funded vocational rehabilitation organization in the Pacific Northwest, at a time when the organization was negotiating financial cutbacks and organizational changes. The model - known as Strengths in Action - was based on Senge's five learning organization disciplines, and informed by organizational culture theory. In each participating office, all staff worked together to set a goal, make a plan, and achieve the …

The Geology And Petrology Of Enigmatic Rhyolites At Graveyard And Gordon Buttes, Mount Hood Quadrangle, Oregon, Elizabeth G. Westby

Dissertations and Theses

Rhyolite lava flows are found at two dome complexes at Graveyard Butte and Gordon Butte, Mount Hood Quadrangle, Oregon. At Graveyard Butte, the White River has cut a winding canyon 150 m deep, exposing at its base, a 40-meter-thick outcrop of flow-banded rhyolite (73 wt.% SiO₂, 3.67±0.01 Ma) that laterally extends along the canyon wall for about 1 km. Stratigraphically above the flow-banded rhyolite is locally-erupted iron-rich andesites (lava flows, agglutinate and other pyroclastic rocks as well as clastic debris), a rhyolitic ash-flow tuff (74 wt.% SiO₂), and the 2.77±0.36 Ma tholeiitic basalt lava flows of …

New 4-Aminoquinoline Compounds To Reverse Drug Resistance In P. Falciparum Malaria, And A Survey Of Early European Antimalarial Treatments, Katherine May Liebman

Dissertations and Theses

Intermittent fevers caused by Plasmodium parasites have been known for millennia, and have caused untold human suffering. Today, millions of people are afflicted by malaria each year, and hundreds of thousands die. Historically, the most successful synthetic antimalarial drug was chloroquine, as it was safe, inexpensive, and highly efficacious. However, plasmodial resistance to chloroquine now greatly limits its utility. Previously in our laboratories it has been shown that attachment of a "reversal agent moiety" to the side chain of chloroquine can result in the restoration of activity against chloroquine-resistant strains of P. falciparum malaria. In the first part of the …

The Objective Vs. The Perceived Environment: What Matters For Active Travel, Liang Ma

Dissertations and Theses

This study aims to explore the relationship between the objective (actual) environment and people's perceptions of the environment, and their relative effects on active travel behavior, particularly bicycling behavior. This is an important research gap in the current literature linking the built environment and active travel. Better understanding this relationship will help to explore the mechanism underlying the built environment- behavior relationship and identify potential interventions to promote active travel.

Relying on the data from Portland, OR, this study investigated the following four research questions: (1) How does the objectively measured environment correspond to the perceived environment? And what factors …

Understanding Sexual Assault Survivors' Willingness To Participate In The Judicial System, Mildred Ann Davis

Dissertations and Theses

This dissertation examined the relationship between support services for adult survivors of sexual assault and judicial outcomes. Specifically, this study explored survivors' willingness to participate in the judicial process. Although "victim unwilling to participate" is the primary reason given by the police for cases not progressing to prosecution, we know little about most aspects of survivors' willingness to participate in the judicial process, especially beyond initial reporting of the assault. The steps to prosecution are dependent on one another yet a survivor's willingness to participate in these steps is a fluid process. The primary research question explored was Are there …

The Role Of Mate Preference And Personality On Reproductive Performance In An Ex-Situ Conservation Breeding Program For The Giant Panda (Ailuropoda Melanoleuca), Meghan S. Martin

Dissertations and Theses

Successful captive-breeding and re-introduction programs must have the ability to breed a surplus of genetically suitable animals for release into the wild. Unfortunately, many individuals in captive breeding programs often do not reproduce even when they are apparently healthy and presented with genetically appropriate mates. Mate choice can affect multiple parameters of reproductive sperformance, including mating success, offspring production, survival, and fecundity. We investigated the role of mate preference and personality on the reproductive performance of male and female giant pandas (Ailuropoda melanoleuca) as measured by intromission success and litter production. We conducted these studies on giant pandas at the …

From The Whiteboard To The Web: Equipping Administrators To Recruit, Hire, And Induct Top Quality K-12 Online Teachers, Daniel Keith Huld

Dissertations and Theses

Online learning is taking our nation by storm and changing the face of education forever. By 2014 we are projected to have 10 million students taking at least one online class (Nagel, 2009). The online revolution is one of the greatest changes the field of education has seen in the last 25 years (Greenway & Vanourek, 2006). This major shift in education also represents a major shift in how our teachers are prepared and what great teaching looks like in online settings.

The online classroom is distinctly different than the brick-and-mortar classroom, and success in the classroom does not necessarily …

Strontium, Lead, And Oxygen Isotopic Signatures Of Mid-Miocene Silicic Volcanism In Eastern Oregon, Emily Nancy Hess

Dissertations and Theses

Widespread, mid-Miocene rhyolite volcanism of eastern Oregon that are coeval or slightly postdate flood basalts of the Columbia River Basalt Province allows for mapping crustal domains using radiogenic and stable isotopes. Rhyolites are thought to be derived in large part by partial melting of the crust and thus yield direct information on the composition of the crust. Silicic volcanism is expressed in the form of numerous domes and tuffs exposed over a wide area (~300 km in N-S dimension and ~200 km in E-W dimension) west of the presumed craton boundary, which runs parallel but mostly east of the Oregon-Idaho …

An Exploratory Study Of Teachers' Uses Of Data To Understand Students' Cognitive And Affective Engagement, Nicole Van Gasse

Dissertations and Theses

Since its introduction in the 1980's, student engagement has been a popular topic in educational research. In the beginning, engagement was thought of as a simple construct; however, it is now believed that student engagement involves four separate, but equally important components (Appleton, 2012; Christenson, Reschly, Appleton, Berman, Spanjers, & Varro, 2008). The components of academic, behavioral, affective and cognitive engagement are each vital to the ongoing educational success of students, and ideally, these would remain high throughout all of the years that students are in school. Unfortunately, research shows that most students' engagement levels continuously decrease from elementary school …

Changing The Face Of The Earth: The Morrison-­Knudsen Corporation As Partner To The U.S. Federal Government, Christopher S. Blanchard

Dissertations and Theses

Beginning with reclamation projects in the western U.S., the heavy construction industry helped the federal government grow in size and sophistication in the twentieth century. The Morrison-­Knudsen Corporation throughout the twentieth century represented one of the federal government's favored contractors. Following western reclamation projects, the U.S. federal government then used contractors to help move the U.S. economy out of the Depression, prepare for World War II, wage the Cold War at home and abroad, and win the space race. Thus, at key stages in United States history we observe the necessity of the U.S. federal government partnering with the heavy …

Chemical And Petrographic Survey Of Large, Igneous-Textured Inclusions In Ordinary Chondrites, Katherine Armstrong

Dissertations and Theses

Our inventory of material from the early solar system includes large, igneous-textured inclusions in O chondrites, whose origin and relationship to their host meteorite is unclear. These inclusions occur in approximately 4% of O chondrites, and are mineralogically, petrographically, and chemically diverse. Petrographic and chemical data from 29 inclusions from 23 host meteorites were collected with optical light and scanning electron microscopy, allowing for the determination of major phase modal abundance and major element bulk chemistry. No correlation between any inclusion property and host meteorite type were found, but some trends were observed. Nine of the inclusions show strong evidence, …

Cascades Island Lamprey Passage Structure: Evaluating Passage And Migration Following Structure Modifications, Siena Marie Lopez-Johnston

Dissertations and Theses

Pacific lamprey (Entosphenus tridentatus), an endemic species to the Columbia River Basin, U.S.A, has experienced staggering decreases in returns to spawning territories in recent decades. As lamprey are threatened severely by a lack of passage at mainstem dams, lamprey specific passage structures have been designed and constructed to address the problem. The Cascades Island Lamprey Passage Structure (LPS) at Bonneville Dam is the longest and steepest structure of its type, following the addition of an exit pipe which allows lampreys to travel from the tailrace of the dam to the forebay. The intent of this study was to …

Early Childhood Educators' Perception Of Oregon's Professional Development System: A Hermeneutic Phenomenological Study, Ingrid Anderson

Dissertations and Theses

Since 2011, the state of Oregon has embarked on a comprehensive educational policy change to create a unified birth to twenty educational system. As part of the birth to age five early childhood and family investment strategy, mandated participation in Oregon professional development system is required for all early childhood educators working in Office of Child Care licensed programs. To date, research on early childhood educators' experience in professional development systems has focused primarily on experiences with regulatory systems. This hermeneutic phenomenological study explored how four early childhood educators made meaning of their experiences of professional engagement in Oregon's state …

Assessing Generic And Program-Specific Dose-Response Relations Between Engagement In Contemplative Practices And Reductions In Teachers' Occupational Stress And Burnout, Jessica Leigh Harrison

Dissertations and Theses

Teaching is a stressful, uncertain, and emotionally laden profession (Chaplain, 2008; Farber, 1999; Johnson et al., 2005). One approach to reduce psychological distress and improve well-being in teachers is through the use of mindfulness-based stress reduction (MBSR) programs. While MBSR programs have been shown in several studies to be effective with regard to improving well-being in teachers, little research has been done to date examining the relationship between program dose and outcomes. This study examines the relationship between both generic and program-specific dose and outcomes of stress and burnout. Results showed some evidence that generic yoga frequency is related to …

Selective Indicators For Optical Determination Of Disease Biomarkers, Lovemore Hakuna

Dissertations and Theses

The most abundant biological thiols, homocysteine (Hcy), cysteine (Cys) and glutathione (GSH) have been the subject of intense research due to their association with a wide range of diseases. They play a key role in maintaining the redox status of biological systems. Selective detection methods for these thiols are challenging due to their similar structures and properties. Current commercially available detection methods use separations, fragile and expensive enzymatic or immunogenic materials and complex instrumentation. This has led to a global effort towards developing simple and inexpensive optical probes and indicators selective for specific biological thiols.

Highly selective chemical probes and …

The Power Of Reflective Professional Development In Changing Elementary School Teachers' Instructional Practices, Carolina Christmann Cavedon

Dissertations and Theses

With the new goal of K-12 education being to prepare students to be college and career ready at the end of high school, education needs to start changing at the elementary school level. The literature suggests that teachers need reflective professional development (PD) to effectively teach to the new standards and to demonstrate change to their current instructional practices. This mixed-method multiple-case study investigated the impacts of a reflective professional development (PD) in changing elementary school teachers' instructional practices.

Teachers Instructional Portfolios (TIPs) were scored with a TIP rubric based on best practices in teaching mathematics problem-solving and science inquiry. …

Street Level Food Networks: Understanding Ethnic Food Cart Supply Chains In Eastern Portland, Or, Alexander G. Novie

Dissertations and Theses

Portland, OR, is the site of a unique urban food cart phenomenon that provides opportunities for small business ownership and access points for culturally specific food for the city's foreign-born and minority populations. Known as a "foodie haven," Portland also has an active sustainable food movement with engaged citizens and support from city and regional policies aimed at significantly increasing the consumption of local food. To date, there have been no in-depth studies on the sourcing habits of Portland food cart owners and whether or not these street-level actors are involved in the area's local alternative food movements (AFNs). The …

Evaluation Of Energy Policy Instruments For The Adoption Of Renewable Energy: Case Of Wind Energy In The Pacific Northwest U.S., Remal Abotah

Dissertations and Theses

The wide use of renewable energy technologies for generating electricity can be seen as one way of meeting environmental and climate change challenges along with a progression to a low-carbon economy. A large number of policy instruments have been formed and employed to support the adoption of renewable energy technologies in the power generation sector. However, the success of these policies in achieving their goals relies on how effective they are in satisfying their targets and thus increasing renewable energy adoption. One measurement for effectiveness of policy instruments can be their contribution to the input of the process of renewable …
