Spatial Analysis Of Burn Severity And Streamflow Response In The Western Conus, Will Brendan Long

Dissertations and Theses

Wildfire increases the magnitude of runoff in catchments, which can lead to the degradation of ecosystems, risk to infrastructure, and loss of life. The Labor Day Fires of 2020 provided an opportunity to compare multiple large and severe wildfires with the objective of determining potential changes to hydrologic processes in Oregon Cascades watersheds. Geographic information systems (GIS) were implemented to determine the total percentage burned and percentage of high burn severity class of six watersheds on the west-slope of the Oregon Cascade Range. In addition, two control watersheds were included to contrast the influence of climatic effects. Spatial arrangement of …

Targeting The Maladaptive Effects Of Binge Drinking On Circadian Gene Expression, Courtney Ledford

University Honors Theses

Previous studies 1) support a role of circadian genes in regulating alcohol intake, and 2) reveal that harmful alcohol use alters circadian rhythms. However, there [is] minimal knowledge of the effects of chronic alcohol processes on rhythmic circadian gene expression across brain regions important for circadian biology and alcohol intake. Therefore, the present study sought to test the effects of chronic binge-like drinking on diurnal circadian gene rhythms in the master circadian pacemaker (SCN), the ventral tegmental area (VTA), and the nucleus accumbens (NAc) in High Drinking in the Dark-1 (HDID-1) mice, a unique genetic risk model for drinking to …

Investigation Of Basal Imnaha Basalt Flows And Their Relationship To The Picture Gorge Basalt Of The Columbia River Basalt Group, Luke James Fredenberg

Dissertations and Theses

The lower American Bar flows (AB 1 and 2) of the Imnaha Basalt have previously been observed as being chemically similar to those of the Picture Gorge Basalt (PGB). Previous age data separate eruption of the Imnaha and Picture Gorge Basalts by approximately 1.5 Ma, precluding the possibility of a genetic link between the two basalt units. New age data for the Picture Gorge Basalt has expanded the eruptive timeframe and the earliest flows coincide with the eruption of the Imnaha Basalt, making it possible that the lower American Bar flows of the Imnaha Basalt and the Picture Gorge Basalt …

Health Literacy And People Diagnosed With Mental Illness, Beckie Child

Dissertations and Theses

Health literacy is a well-studied concept that has a large literature base. Yet, little is known about health literacy and people diagnosed with mental illnesses, and even less health literacy research speaks to people diagnosed with mental illness. I used a framework and approach of lived experience of psychiatric diagnosis and psychiatric survivor research to conceptualize and inform the study. It explores health literacy with people diagnosed with mental and physical health diagnoses using a small quantitative survey, focus groups, and an individual interview. The findings suggest that health literacy is a dynamic and complex construct that interacts with the …

Reconceiving The Relationship Between The Built Environment And Walking Behavior: Examining The Samples, Scales, And Methods In Travel Behavior Research, Jaime Pablo Orrego-Oñate

Dissertations and Theses

This dissertation aims to formulate a mechanism for the relationship between the urban form and walking choice that can be consistent across contexts. The motivation is the lack of concordant results in the magnitude of the environmental influence on walking choice in urban areas found in the literature. The dissertation identifies a series of limitations in previous research that could cause mixed results in the magnitudes of the association. This research elaborates an approach to overcome these limitations by proposing a mechanism of the activity density over walking modal share by controlling for trip distance distribution. The aim is an …

Does Instructional Autonomy Matter? Exploring Job Satisfaction For Math And Non-Math Teachers In Low, Middle, And High Ses Schools, Hannah Sean Ellefritz

Dissertations and Theses

Throughout the 2000s, standards-based education policies decreased the autonomy of public schools across the U.S., deprofessionalizing educators and limiting their participation in the development of curriculum and instructional policy. Many education scholars argue that, rather than professionals with specialized skills and knowledge, standards-based reforms position teachers as technicians, accountable for measurable output in accordance with externally imposed standards. This literature suggests that such education policies may have implications for teachers’ job satisfaction, especially those working in schools or subject fields that are particularly susceptible to standardized curriculum and accountability procedures. Using nationally representative data from the Teaching and Learning International …

The Intersectionality Of Stuttering And Aging, Mary Elizabeth Herring

University Honors Theses

The purpose of this study is to explore relationships between stuttering and aging so that speech-language pathologists can be informed about the intersectionality of these identities.

Three adult men who stutter, all over the age of 65, were interviewed in semi-structured interviews. Interview transcripts were analyzed with in-vivo coding to find codes and themes between participants. From the interviews, 20 categories were identified. These categories were then funneled into four overarching themes: 1) Personal factors impacted by stuttering, 2) Stuttering perspectives across the lifespan, 3) Stuttering therapy experiences, and 4) Covert stuttering.

This study shows that attitudes, perspectives, and experiences …

An Analysis Of The Strengths And Weaknesses Of The Tulsa Remote Program, As An Effective Economic Development Strategy, Kristen J. Padilla

Dissertations and Theses

Cities do not exist in a vacuum. They are in constant competition for talented, educated individuals and growing, innovative businesses -even if that competition is not explicit or specific. Traditionally cities have been left with two economic development paths to help diversify their economies: attract talent but without jobs, or attract business but without a strong talent pool. However, due to technological advancements, exacerbated by the pandemic, a new and growing workforce that can work from anywhere has emerged, remote workers. This talent pool shifts traditional economic development attraction strategies from city to industry to city to talent.

Many remote …

A Look At The Missing And Murdered Indigenous Women Crisis: Investigation Of Potential Causes And Effects, Verity Saige Vogel

University Honors Theses

In North America, Indigenous women go missing and are murdered at a rate higher than any other demographic. Scholars and governmental agencies agree that the Missing and Murdered Indigenous Women (MMIW) crisis is a pressing issue; it was not until a series of successful social media campaigns (using the hashtag #MMIW) and other grassroots activism took root across First Nations and Native communities in North America that the gravity of the situation became widely reported. Although many agree that the MMIW crisis is a wicked problem (in that it has many contributing factors that amplify its effect and contribute to …

Characterizing The Single-Photon State: Quantum Physics Experiments With Single-Photon Sensitivity, Sheldon Lee Field

Batterer Intervention Program Evaluation: A Portland, Oregon Program Case Study, Julie M. Conner

University Honors Theses

Batterer intervention programming (BIP) has shown up as a source of treatment for men who abuse women since the late nineteen-seventies and have since continued to expand. Research has been done to examine how effective these programs are in many different settings at reducing intimate partner violence, but little is known about programs specific to the state of Oregon. BIPs are used as an alternative to incarceration for individuals convicted of domestic violence: existing programs are based on the Duluth Model and Cognitive Behavioral Theory (CBT). Other modalities have utilized trauma-informed approaches, psychoeducation, holistic modeling, and risks, need, and responsivity …

Examining Emergency Citizen Response To The Covid-19 Pandemic: Emergent Groups Addressing Food Insecurity In Portland, Oregon, Aliza Ruth Tuttle

Dissertations and Theses

Emergency response agencies commonly focus on how hard infrastructure will interact with extreme climatic and geologic events: bridges during an earthquake and buildings following a tornado, for example. Peoples' actual experience of these extreme events vary, however, based on socially constructed consequences of natural hazard events and their interaction with a depleted or robust social safety net.

Previous research shows people living with depleted social safety nets and who experience a natural hazard event are likely to help where they see disaster. Individuals consistently form groups, called emergent groups, to organize their efforts. This research explored emergent groups that formed …

A Typology Of Foster Home Quality Elements In Relation To Foster Youth Mental Health, Paul Sorenson

Dissertations and Theses

Foster care has been one of the primary interventions in society's efforts to address child maltreatment. The foster parents and foster homes follow a process of certification intended to ensure that maltreated children be placed in substitute care that supports and encourages positive outcomes. One of the outcomes of principle concern is mental health. Few studies have been conducted that explore the makeup of certified foster homes with respect to the cumulative impact of multiple indicators of quality on mental health outcomes of foster youth.

This study sought to identify a typology of foster homes based on theorized indicators of …

How Domestic Violence Affects Incarcerated Women, Michelle Ryman

University Honors Theses

The incarceration of women has grown seven times since the 1980s, with up to 90% of incarcerated women being survivors of domestic violence. Women are five times more likely to be abused by an intimate partner. Intimate partner violence leads to unhealthy coping mechanisms like drug abuse and violence against perpetrators. While coercion in IPV can contribute to violent retaliation and drug abuse, it can also lead to criminal behavior prompted by the perpetrator. Whether IPV shows itself as violent attacks, sexual assault, coercion, financial withholding, threats, isolation, psychological abuse, or any other behavior that allows one person to control …

Post-Fire Erosional And Hydrological Processes Promoting Debris Flow Initiation In A Douglas Fir And Western Hemlock Forest In The Riverside Burn Area, Oregon, Morena Nicole Hammer

Dissertations and Theses

Post-fire debris flows initiated by overland flow in the Pacific Northwest (PNW) are largely undocumented. Instead, debris flows are typically initiated by shallow landslides that result in a mud slurry of water and sediments traveling downhill under the force of gravity. However, because of the Fall 2020 fires in Oregon, the typical initiation style and erosional patterns in burned catchments may have changed because of unusually high burn severity. Due to the intensity of these fires, we set out to determine how hydrologic processes and erosion occurred, when they occurred, and what process was primarily responsible for the erosion that …

Prevention Of Deep Vein Thrombosis In Obese Trauma Patients, Sarah Autry

University Honors Theses

Deep vein thrombosis (DVT) is a frequent occurrence in trauma patients secondary to traumatic injury due to immobilization, reparative surgeries, and procedures, if no/minimal prophylaxis is utilized. Obesity has been shown to increase the risk of venous thromboembolism (VTE) by 2 to 3 times. The current DVT data may not discriminate between patient demographics that affect venous thromboembolisms (VTE) and chemoprophylaxis, such as weight or body mass index (BMI). A retrospective data analysis was performed using data collected from Oregon Health & Science University’s Trauma Registry that includes trauma patients admitted between January 2017 and December 2020, ≥17 years of …

The Right To The University: The Experiences Of Mexican/Mexican American/Xicanx Students At A Predominantly White University In Upstate New York, Martín Alberto Gonzalez

Chicano/Latino Studies Faculty Publications and Presentations

Having the right to a space is not only the right to be present without being harassed or bothered, but it also includes the right to have a say in how that space should be experienced. Yet, spaces have long been contested and not everyone has equal access to shared spaces. This paper examines the experiences of Mexican/Mexican American/Xicanx (MMAX) undergraduate students at a predominantly white university in the Northeast. Drawing on indepth interviews, participant observations, pláticas, and document analyses, I argue that MMAX students do not have the right to their respective university because their university does not address …

A New Studio Era: How Netflix Is Becoming A Threat To The Film Industry, Al Kasper

University Honors Theses

Movie streaming services have become an increasingly popular distribution method due to their widespread accessibility to film content across the globe. Netflix is the biggest competitor of movie streaming services and has led the charge in creating original content for its customers. With many of these streaming services creating their own content, both Hollywood and independent studios are being introduced to a new competitor in their market: studios that stream their own content. While this may seem to be an issue only within the industry, there are concerns about another oligarchy of studios being created out of these streaming services …

Science Education Research On Student To Student Discourse: A Literature Review With An Applied Linguistics Lens, Abbee A. Mortensen

University Honors Theses

Science education researchers have increasingly been using discourse analysis to research small group discussion while doing course related activities. This literature review examined studies from that discourse community to see what analysis methods were used and if they connected to applied linguistics theories or methods. Two of the most common discourse analysis frameworks used were Toulmin's Argument Pattern and grounded coding schemes that looked at the design and specific contents of the discourse. Studies covered will also include education scholars using theories of conversation analysis and normative pragmatics to make a more explicit connection to applied linguistics. Orienting and drawing …

Together Or Apart? The Effects A Parent's Relationship Dynamic Has On Their Child(Ren)'S Romantic Relationship, Kailee Delos Santos

University Honors Theses

The relationship between parents is considered one of the most influential interactions a child will experience; as it is usually the first relationship a child witnesses where personal values and interests develop (Stanger, 2019). Nonetheless, it is a consistently understudied population in family research and, when studied, children are primarily examined during adolescence and often only in the context of conflict and rivalry. Additionally, much of this research does not examine the effects of a child's romantic relationship on the larger family system. This thesis seeks to address this gap in the literature by understanding how the relationship of a …
