Dissertations and Theses

Our institutional approaches to problems in the changing global landscape of internationalized higher education are being challenged, and many scholars call for new approaches for understanding and addressing the complex problems we face (e.g., la paperson). The COVID-19 pandemic has sped up the need to make changes in how we approach our evolving problems and possibilities for human-centric transformation. This multi-paper dissertation is a call to action and proposes the use of new approaches to research and educational practice--specifically, critical futures studies and arts-based research. Design justice principles and participatory action approaches frame and motivate these possibilities. First, "A Public …

Mapping Ecosystem Service Flows Of Estuary Restoration Projects On The Oregon Coast To Identify Impacted Stakeholders, Shersten King Finley

Dissertations and Theses

The recent impetus for estuarine restoration has largely focused on resolving key ecological problems; however, less is known about how people might benefit or be impacted by restoration. By mapping benefits that flow from functional salt marshes and estuarine systems I examined how different social groups might be impacted by restoration based on race and class. In this study, I considered three ecosystem services (recreation, aesthetics, cultural/historical/spiritual) and where they might impact surrounding communities. In this paper I argue that stakeholder groups can be identified by mapping ecosystem service flow areas. I hypothesized that these three ecosystem services would have …

A Three-Dimensional, Analytical Wind Turbine Wake Model: Flow Acceleration, Empirical Correlations, And Continuity, Zein Ahmad Sadek

Dissertations and Theses

A new, three-dimensional, analytical, steady state wake model is presented which includes local flow acceleration near the rotor improving wake description compared to existing models. Wake structures such as the momentum deficit and regions of accelerated flow are concisely described with compound and normal Gaussian functions. Large-eddy simulations (LES) are used as training data to develop the model using two, inline turbines under various inflow conditions parameterized by hub height wind speed and turbulence intensity. Mass conservation is considered by fixing two components of the wake velocity model and optimizing the third to best satisfy continuity; after which, the model …

Radiation Isolation And The Impact Of Care: Nursing Knowledge And Perception Of Radiation Risks, Bae P. Chu

Dissertations and Theses

Background: The safety challenges encountered when employing ionizing radiation to treat patients and manage radiation exposure and contamination have been well established in previous research. However, little is known about nurses’ understanding of the risks associated with ionizing radiation and how they respond to their own perceptions of risk. Although a wealth of literature shows an association between radiation treatment and negative patient experiences, there remains a lack of understanding of the basis of these perceptions among nurses. Increased ionizing radiation diagnoses and treatment means that nurses are at a higher risk of radiation exposure today than thirty years ago. …

Geochronological And Geochemical Investigation Into Rhyolite Volcanism Of The High Lava Plains And Columbia River Basalt Group Provinces Of Eastern Oregon, Usa, Vanessa Marie Swenton

Dissertations and Theses

Voluminous and widespread bimodal volcanism has significantly impacted the Pacific Northwest, USA, throughout the Miocene to present day. The two primary volcanic provinces of eastern Oregon include the Columbia River Basalt Group (CRBG) province and the High Lava Plains (HLP) trend. The magmatic and tectonic processes responsible for generating bimodal volcanism, and particularly rhyolites of the ~17-15 Ma CRBG and 12-0 Ma HLP provinces has recently been a popular topic of debate. Rhyolite volcanism of the HLP province has been ascribed to either buoyancy-driven westward plume spreading or to slab rollback and mantle convection spanning from southeast Oregon to Newberry …

An Examination Of Educator Perspectives On Career And College Pathways For Black, Indigenous, And Students Of Color With Disabilities, Rachel Anne Herrick

Dissertations and Theses

Black, Indigenous, and students of color (BIPOC students) in high school, who are dually experiencing the socially constructed labels of race and disability (BIPOC-SWD), are not provided with equitable access to Career and College Pathway (CCP) programs, which contributes to a lack of preparedness and success within postsecondary settings. Despite school reform policy efforts that incorporate Culturally Relevant Pedagogy (CRP) and Career and College Readiness frameworks, BIPOC-SWD perpetually have lower achievement rates, poorer postsecondary outcomes, and are less prepared for careers or college.

Utilizing a Disability Critical Race Theory (DisCrit) lens, this comparative case study was used to examine educator …

Assessment Of Spatial And Temporal Trends Of Exposure To Ambient Fine Particulate Matter And Ozone In New York/New Jersey Metropolitan Area, Subraham Singh

Dissertations and Theses

Background. Exposures to fine particulate matter (PM_2.5; particles with diameter less than 2.5 μm) and ozone (O₃) affect premature respiratory and cardiovascular mortality, morbidity and contribute to the development and progression of sub-clinical and clinical disease. Climate change affects air quality directly by modifying the thermodynamic properties of formation mechanisms and transport patterns, and indirectly, through increased emissions of PM_2.5 and O₃ precursors. The resultant changes in air quality influence human health outcomes through mechanisms of varying scale, timing, and complexity. PM_2.5 and O₃ levels have been declining due to the implementation …

Neighborhood Predictors Of E-Cigarette Retailer Density In New York City, Laena Orkin-Prol

Dissertations and Theses

Background: The rampant expansion of the e-cigarette market over the last decade in the U.S. is a threat to the health of the public—due to the e-cigarette’s appeal to young people, addictiveness, and harms of consumption. It is vital to study the distribution of e-cigarette retailers of different types in major urban centers, such as New York City (NYC), to identify if certain neighborhoods are overburdened with retailers and if intervention is required. The current research on the e-cigarette retailer environment is limited in its scope and methods used.

Objective: To investigate neighborhood attributes associated with e-cigarette retailer density in …

Factors Related To Contraceptive Use And Family Planning Decision-Making In The South Asian Community Residing In New York City, Nandini Shroff

Dissertations and Theses

Introduction: Currently, there are approximately 5.4 million South Asians residing in the United States (U.S.). The limited literature illustrates that contraceptive use is underutilized among Asians and Asian sub-groups, including South Asian Americans, compared to other racial and ethnic groups. Using Los Angeles County Health survey data, one study found that 22% of Asian Americans reported always using condom in the past 12 months compared to 37% of African Americans, 27% of Whites, and 27% of Hispanics. A study among New Jersey women revealed that compared to non-South Asian women, South Asians (SAs) were less likely to have used ever …

Investigation Of The Association Of Exposures To Fire-Related Hazards With Pulmonary Function Of Firefighters, David G. Goldfarb

Dissertations and Theses

Background. Firefighters are habitually exposed to hazardous toxicants which place them at an elevated risk for numerous adverse health outcomes. An example of this is the associations observed in other works between inhalation of combustion byproducts from urban structural fires and both acute and chronic pulmonary dysfunction. To-date, the characterization of firefighters’ exposures to dangerous chemicals in smoke from non-wildfire incidents, both directly through personal monitoring and indirectly from work-related records is scarce. Prior works investigating the association between routine firefighting and pulmonary function have relied on crude metrics such as years of service and numbers of responses to …

A New Approach To Machine Learning Hardware Classifier Design Based On Functional Decomposition Of Multi-Valued Functions, Saad Mohammad Al-Askaar

Dissertations and Theses

This dissertation presents a novel design of a hardware classifier based on combining modified Ashenhurst-Curtis Decomposition and multiplexer-based synthesis. The PSUD classifier brings three new contributions: an approach to solve the column multiplicity problem, an approach to encode multiple-valued variables, and a decomposition algorithm based on modified Ashenhurst-Curtis Decomposition. One of the biggest challenges in Boolean function decomposition is the variable partitioning problem. Thus, we introduce a new representation of two combined classifiers for multiple-valued functions to overcome the variable partitioning problem which allows finding the minimal column multiplicity and consequently to find high quality decompositions leading to a good …

A Bayesian Latent Scale Model For Multivariate Longitudinal Data, Kruti Pandya

Dissertations and Theses

In order to understand the entire course of slow progressing diseases like Alzheimer's dementia or multiple sclerosis, it is essential to characterize long term disease dynamics from a healthy stage to a late disease stage. Cohort studies typically recruit subjects at different stages of the disease and then follow them for a relatively short period of time. In this dissertation, we propose a novel Bayesian nonlinear mixed effects model with latent time scale to characterize long term disease dynamics using the observed short term longitudinal data from cohort studies without relying on clinical diagnosis. This model can accommodate noisy longitudinal …

Methodologies For Quantum Circuit And Algorithm Design At Low And High Levels, Edison Tsai

Dissertations and Theses

Although the concept of quantum computing has existed for decades, the technology needed to successfully implement a quantum computing system has not yet reached the level of sophistication, reliability, and scalability necessary for commercial viability until very recently. Significant progress on this front was made in the past few years, with IBM planning to create a 1000-qubit chip by the end of 2023, and Google already claiming to have achieved quantum supremacy. Other major industry players such as Intel and Microsoft have also invested significant amounts of resources into quantum computing research.

Any viable computing system requires both hardware and …

The Global Implementation Of Dolutegravir For Hiv Treatment, Matthew L. Romo

Dissertations and Theses

Background
Dolutegravir, an integrase strand transfer inhibitor, is now recommended by international guidelines as part of preferred antiretroviral therapy (ART) regimens for people living with HIV. In low- and middle-income countries (LMICs), HIV treatment programs are transitioning from non-nucleoside reverse transcriptase inhibitors (NNRTIs) to dolutegravir because of its superior efficacy and tolerability, and high genetic barrier to HIV drug resistance. Along with the optimism surrounding widespread dolutegravir use, key questions regarding its implementation have emerged. In this dissertation, I sought to achieve the following specific aims: Aim 1: Characterize dolutegravir uptake in LMICs and identify potential disparities related to sex …

Assessing Psychosocial Factors That Influence Water, Sanitation, And Hygiene Behavior In The Amhara Region Of Ethiopia, Kimberly Kamara

Dissertations and Theses

Background: The absence of potable drinking water from an improved source combined with inadequate sanitation and hygiene contributed to an estimated 1.9% of the global burden of disease in 2016. The estimated number of diarrheal deaths in 2016 was 1.4 million, of which 829,000 could have been prevented through improved drinking water and sanitation services, and hand-washing with soap. Despite the clear link between poor water and sanitation access and hygiene practices, 785 million people do not have access to water and two million do not have access to basic sanitation services. However, access does not automatically result in increased …

Episode Based Payment Models and the Hospital Safety-net: An Evaluation of the Center for Medicare and Medicaid Services’ Comprehensive Joint Replacement Bundled Payment Program

By John Anthony Gravina

Advisor: Alexis Pozen, Ph.D.

Introduction: Payments for Healthcare services are increasingly being tied to clinical quality, patient experience, health outcomes, and efficiency through value-based payment arrangements (VBP). VBP presents a potential opportunity to reduce healthcare expenditures by requiring providers to take on financial risk associated with the cost and quality of care, therefore aligning payment incentives with the goals of providing higher quality and efficient care. As of 2020, 80 percent of …

Scenario Acceleration Through Automated Modelling: A Method And System For Creating Traceable Quantitative Future Scenarios Based On Fcm System Modeling And Natural Language Processing, Christopher W.H. Davis

Dissertations and Theses

Scenario planning is used extensively in strategic planning because it helps leaders broaden their perspectives and make better decisions by presenting possible futures in story form. Some of the benefits of using scenarios include breaking away from groupthink, creating better products, acceleration of organization learning and reducing bias. Product development teams, particularly for digital products, are gaining more autonomy in organizations and tend to manage risk by undergoing very short development iterations on their products while leaning on their consumers for feedback -- a process known as agile development. This method tends to limit the perspective of the team and …

Observation And Control Of Photoemission And Electric Field Enhancement Of Plasmonic Antennas Through Photoemission Electron Microscopy, Christopher M. Scheffler

Dissertations and Theses

Photoemission electron microscopy (PEEM) is an imaging method which uses electrons excited through the photoelectric effect to characterize a sample surface with nanometer-level resolution. In PEEM, a high intensity laser excites electrons from the surface of the material and electron optics are used to form an image from the intensity and spatial distribution of the photoemission from the sample. The goal of this research was to study and maximize light confinement, which was accomplished using plasmonic nanostructures. Surface plasmons represent oscillations in the electron density of a material and can occur along the transition interface between a metal and a …

People with amyotrophic lateral sclerosis (ALS) often experience changes to their speech, and may use augmentative and alternative communication (AAC) devices and techniques to maintain the ability to communicate. The use of AAC may facilitate the participation of people with ALS in various life situations involving communication. There is limited data in the literature about the AAC approaches currently used by people with ALS, the professional services they receive to support communication, or the effects of AAC on their communicative participation. This dissertation involved a nationwide online survey of people with ALS, and comprises three papers intended to add to …

"I Just Had To Do Most Everything": Gender, Settlement And American Empire In The Far West, Hannah Alexandra Reynolds

Dissertations and Theses

The field of settler colonial studies has made huge strides in recent years toward problematizing the establishment of the United States on stolen land and the nation's steady, violent expansion across the continent. Settler colonial framework provides a rich opportunity for historians of the American West to reframe white settlement on the frontier, especially that which was made possible through land grant legislation such as the Homestead Act of 1862. As the families who took up land grant property sought new opportunities for themselves, they also acted as drivers of U.S. territorial acquisition. This process was inherently gendered, in terms …

Must Be Present To Win: Principals' Perspectives On Exclusionary Discipline, William Jeremy Cohen

Dissertations and Theses

One of the persistent challenges in United States elementary schools is the ongoing use of exclusionary discipline practices. In Oregon, despite the application of a number of legal and policy shifts intended to reduce the use of suspension and expulsion in K-5 and K-8 schools, particularly for students of color, there continues to be an increase year-to-year of the number of students being excluded, the percentage of students excluded, and an increasingly disproportionate use of exclusion for students of color. Although the research shows that removing students from the learning environment does not improve student behavior nor improve overall school …

Developing An Assessment Model For Entrepreneurship Ecosystems Using Hierarchical Decision Model: Case Study Of Riyadh City, Mustafa Kamal Almuzel

Dissertations and Theses

Entrepreneurship is one of the major drivers of economies. Countries that aim to improve their economies by increasing entrepreneurial activities and its effectiveness need to develop an effective entrepreneurship ecosystem. This ecosystem combines a set of domains and factors that create a healthy environment for entrepreneurs. The analysis shows that there is limited research about structured assessment methods to evaluate the entrepreneurship ecosystems.

Therefore, this research objective is to introduce a universal assessment model that can be adopted in different cities for implementing an effective entrepreneurial ecosystem. This will be achieved by addressing three main research questions. 1) What are …

Amplifying Arab American Heritage Language Students' Voices: A Multiple Case Study On Translanguaging Practices And Identity Negotiation In University Arabic Classrooms, Lina Gomaa

Dissertations and Theses

Little research has been conducted on Arab American students at universities and specifically, in the heritage language studies field. The experiences of Arab American heritage language (AAHL) students are significantly less examined than those of other heritage language students. Arabic language curricula and instructional practices in universities tend to privilege the teaching of Modern Standard Arabic over dialects, which marginalizes heritage learners' prior knowledge of the Arabic culture and its language, specifically Arabic dialects used in their home communities. These phenomena can create a non-affirming learning experience for these students. As such, in this study, I addressed these questions:

• To …

Transformative Ecoliteracy Development In Postsecondary Education: Cultivating Intentional Relationships Through Garden-Based Learning, Shevawn Armstrong

Dissertations and Theses

Education can play a critical role in empowering learners to address the global, complex, and interconnected sustainability problems humanity currently faces. Ecoliteracy, as an educational aim, may support the cultivation of values, attitudes, and skills required for the development of sustainability solutions and our collective ability to design regenerative ways of living. However, empirical research that explores and supports the development of ecoliteracy in adults is limited. This grounded theory action research study aimed to contribute to this body of knowledge. This study explored how adult ecoliteracy and practical gardening skills may be cultivated through an intentionally designed, holistic, garden-based …

Synthesis Of Diaryl And Alkyl-Aryl Ethers Via Diaryl Iodonium Reagents, Rory Tennessee Gallagher

Dissertations and Theses

Substituted benzenoid rings are a prevalent motif in many industries including high tech, agrochemicals, and pharmaceuticals. As a result, the arylation of chemical compounds is a highly sought-after chemical transformation. There are many literature methods to achieve this chemical transformation, nucleophilic aromatic substitution and transition metal catalysis are both widely used and studied. Diaryliodonium salt mediated chemistry is an attractive alternative to these methods as it does not require the expensive toxic metals and designer ligands of transition metal catalysis and is not restricted to electron deficient aryl rings with specific substitution patterns like nucleophilic aromatic substitution.

Many diaryliodonium salt …

Cultural Capital And Community Cultural Wealth: A Study Of Latinx First Generation College Students, Affiong Eyo-Idahor

Dissertations and Theses

When compared to Blacks, Asians, and Whites, Latinxs have lower rates of educational attainment at every level from secondary education to advanced postsecondary degrees (Ryan and Bauman 2016). This study focuses on Latinx first generation college students and uses Yosso's Community Cultural Wealth (CCW) theory to illuminate the ways this population navigates college through employing the strengths from their home community. The Latinx population is the largest ethnic or racial minority group in the United States (U.S. Census Bureau 2017. By 2060, they are expected to account for nearly 29% of the US population (U.S. Census Bureau 2017). While the …

Developing An Energy Service Interface Specification, Jaime T. Kolln

Dissertations and Theses

Developing an Energy Service Interface (ESI) specification requires engaging a community of stakeholders including grid operators, Information and Communication Technology implementors, integrators, and finally standards bodies who will define an interface that respects and boundaries of ownership and roles of responsibility in order to activate millions of Distributed Energy Resources for the provision of grid services. By applying Interoperability Maturity Model Criteria and ESI principles to common grid-DER service use cases, the Grid Modernization Lab Consortium team will engage subject matter experts to develop a specification, with an eventual goal of informing development of ESI compliant profiles or standards. The …

Japanese Gender Trouble In Revolutionary France: Ikeda Riyoko's Shōjo Manga The Rose Of Versailles, Saki Hirozane

Dissertations and Theses

Although traditional gender norms are reinforced by pop-culture media in Japan, some comics aimed primarily at female readers fight against those same gender norms. Shōjo manga (Japanese girls' comics) are no exception and have done so since their "revolution" in the 1970s. In the 1970s, a new wave of young female shōjo manga artists pioneered a different kind of girls' manga because they created new perspectives for their young female readers.

Ikeda Riyoko's Rose of Versailles (Berusaiyu no bara, 1972-73), set in Revolutionary-Era France, changed how Japanese women could see themselves in the 1970s. In Rose of Versailles …

Testing The Ls/Cmi For Predictive Accuracy: Does Age Matter?, Sandra Stephanie Lawlor

Dissertations and Theses

The Level of Service/Case Management Inventory (LS/CMI) is one of the most widely used instruments for assessing recidivism risk and treatment needs in correctional settings. The predictive validity of the measure and its predecessor (LSI-R) has been established in meta-analytic studies and research finds that the scale's accuracy is largely independent of sex, race, and ethnicity. Whether the LS/CMI works equally well for different age groups remains in question. The current study assessed the predictive accuracy of the LS/CMI from a sample of 14,940 adults in custody (AIC) released from an Oregon prison between 2011 and 2017 for three age …
