Youth marijuana use, which can lead to numerous health problems, is significantly associated with youth drug perception, which is greatly influenced by state marijuana laws such as medical marijuana legalization and penalty severity. The mediating impact of social drug perceptions on the association between state marijuana laws and youth drug disapproval is not well known. Based on theory of change and primary socialization theory, this study examined the impact of state marijuana laws on youth drug disapproval, the mediating factors of parent and peer drug disapproval, the direct effect of youth drug disapproval on youth marijuana use, and the moderating …

Clarifying And Measuring Inclusive Leadership, Kelly Mason Hamilton

Dissertations and Theses

Many organizations view diversity as a strategic business priority that provides important benefits such as increased creativity and innovation. Research indicates, however, that the potential benefits of diversity cannot be realized without employees feeling a sense of inclusion, which involves feeling like one belongs and can be themselves at work. Although scholars acknowledge the important role managers play in fostering inclusion, there remains limited research on specific behaviors they can enact to foster inclusion perceptions in their work groups. Additionally, there is a lack of agreement in the literature about the scope of "inclusive leadership." Historically, scholars viewed inclusive leadership …

Perspectives Of Students With Intellectual And/Or Developmental Disability In College Inclusion Programs On Their Preparation For Working In Competitive Integrated Employment, Eva R. Blixseth

Dissertations and Theses

Individuals with intellectual and developmental disabilities have a history of being isolated, marginalized, and excluded from employment that is competitive and integrated. Policy makers, disability advocates, and self-advocates have made efforts to center inclusive education and employment opportunities for individuals with intellectual disability. Employment is a valuable outcome for students with intellectual and developmental disabilities exiting college inclusion programs (Lee & Colleagues, 2022). However, from 2017 through 2021, not all students with intellectual and/or intellectual disability exiting college inclusion programs were employed. This is concerning as O'Brien et al. (2019) pointed out students' primary goal for completing college inclusion programs …

A Walk In The Park: A Spatial Analysis Of Crime And Portland Parks, Cheyenne Pamela Hodgen

Dissertations and Theses

This thesis presents two individual research papers that examine the relationship between greenspaces and crime in Portland, Oregon. The two papers use an adapted street network buffer to better measure crime concentration around discrete locations. This methodological development allows for an improved measure of crime concentration around discrete locations.

The first contribution, explores the relationship between different greenspace types and crime, breaking down different crime types into discrete categories. The results of this study suggest that overall, Portland greenspaces do not experience a concentration of crime, however, different patterns emerge as greenspace and crime types are disaggregated. Only one greenspace …

Transportation Mode Choice Behavior In The Era Of Autonomous Vehicles: The Application Of Discrete Choice Modeling And Machine Learning, Sangwan Lee

Dissertations and Theses

New mobility technologies, such as shared mobility services (e.g., car-sharing) and, more importantly, autonomous vehicles (AVs), continue to evolve. The supply-side advancement will likely disrupt and transform transportation mode choice behaviors, and create a new paradigm since they are emerging and becoming increasingly feasible alternatives to the existing modes of transportation. Accordingly, this dissertation employs discrete choice modeling (DCM) and machine learning (ML) using a U.S. nationwide stated choice experiment to understand how travelers adopt new transportation modes or continue to use conventional modes of transportation.

This dissertation consists of three papers. The first examines future market shares of each …

"We've Created Cheap Energy Off The Backs Of Salmon": Dam Removal Politics And Alliances In The Lower Snake River Basin, Krista Harrington

Dissertations and Theses

Dams, once considered by many to be good for water development in the Western U.S., might not be a part of a climate resilient future. Dams have come under increasing scrutiny due to undesirable ecological implications. Although dam removal proposals are growingly popular in recent decades, they are controversial since they impact different stakeholders in different ways. In the Pacific Northwest, the Lower four Snake River dams have long been criticized for their negative impacts on salmon. In February 2021, US Congressman Mike Simpson (R-Idaho) proposed a comprehensive framework to deconstruct the Lower four Snake River dams as an attempt …

Professional Development For Special Education Paraeducators: How To Effectively Train Classroom Staff To Support Students With Complex Instructional And Behavioral Needs, Cara Olson-Sawyer

Dissertations and Theses

According to data from U.S. Bureau of Labor and Statistics in 2018, it is estimated that there are 1,308,100 paraeducators employed in public schools in the United States. Despite the prevalence of paraeducators, these employees receive limited opportunity for training. In addition, there is little guidance from the Department of Education or Individuals with Disabilities Education Act (IDEA) for effective professional development and there are no standardized job qualifications or job descriptions across states and school districts. This lack of uniformity, combined with vague job descriptions often result in paraeducators entering the education field with no formal education and training, …

Masculinity Instability And Ideologies As Predictors Of Ipv Perpetration: The Mediating Role Of Relationship Power, Emma Christine Marioles O'Connor

Dissertations and Theses

Intimate partner violence (IPV) is considered to be a pervasive and devastating social issue and is disproportionately perpetrated by men (CDC). Masculinity ideologies, which are comprised of male role norm expectations, inform boys and men about what it means to be and to not be "a man" and have been established as a predictive factor of men's IPV perpetration. These ideologies serve to maintain existing social hierarchies that entitle men to seek socially dominant and powerful positions in society, as well as within their intimate relationships. Further, masculinity is considered to be unstable, subject to threat, and in need of …

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 …

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 …

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. …

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 …

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 …

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 …

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.

This dissertation involved a nationwide online survey of people with ALS, and comprises three papers intended to add to …

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 …

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 …

"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
