How Beavers (Castor Canadensis) Affect Habitat Availability For Two Native Oregon Turtles: Actinemys Marmorata And Chrysemys Picta Bellii, Rodé Krige

University Honors Theses

Oregon is home to two native freshwater turtle species: the northwestern pond turtle and the western painted turtle. Both turtles are Oregon conservation strategy species with a status rating of sensitive, indicating declining populations. Oregon's decline in these turtle's populations is thought to be predominantly due to loss and degradation of habitat that results from development and urbanization. Beavers' ability to dam streams and create ponds may be creating habitat usable by turtles, but the relationship is under-studied. This study assessed water temperature, basking habitat, and overall turtle habitat suitability at beaver-dammed and control ponds in Portland, Oregon. Average basking …

Crossover Youth: The Relationship Between Juvenile Dependency And Delinquency, Victoria Davenport

University Honors Theses

This literature review looks at the relationship between juvenile delinquency and juvenile dependency. Specifically, it evaluates the existence of "crossover youth", minors who have been involved with both systems in their lifetime. The review considers thirteen different studies, literature reviews, and databases to determine risk factors in maltreated youth that cause them to offend. The review also looks at the impact that second-generation parents have on likelihood of offending as juveniles, as well as the importance of welfare worker perception on parental involvement with dependency agencies. Finally, the review considers potential interventions to crossover youth, determining how to assist maltreated …

Critical Consciousness & The Rural-Urban Divide, Kendall O'Rorke

University Honors Theses

This study investigated the relationship between conceptions of Critical Consciousness (CC) and urban vs. rural geographic location type. Participants (N = 31) completed the Short Critical Consciousness Scale (CCS-S), and 25 additional questions regarding potential location-based idealogical differences. No measurable differences were found regarding differences in conceptions of critical consciousness (using CCS-S scores) based on rural-urban location, however, other responses supported some current research regarding political typology. Additional research is needed to fully understand this topic.

Economic Analysis Of Population-Based Next Generation Sequencing For Breast Cancer, Sapphire Curelaru

University Honors Theses

Breast cancer develops due to accumulated DNA replication insults which causes cancer to uncontrollably proliferate. An individual's predisposition to developing cancer, as well as the composition of a tumor, can be sequenced using genetic tests. Myriad's BRACAnalysis CDx^® seems to be the most utilized genetic test. However, Next Generation Sequencing (NGS) seems to be a better genetic test for breast cancer when compared to Myriad's BRACAnalysisCDx^® in terms of return-time, accuracy, efficiency, and healthcare cost. By using Next Generation Sequencing tests, stakeholders can save money on genetic testing which can be invested in more genetic tests. Payers can …

Russian Civic Criticism And The Idyllic Dream In Ivan Goncharov’S “Oblomov”, Cassio De Oliveira

World Languages and Literatures Faculty Publications and Presentations

Nikolai Dobroliubov’s and Dmitrii Pisarev’s reviews of Ivan Goncharov’s novel Oblomov have gone into history as exemplars of Russian civic criticism. Their main argument centers on the eponymous protagonist’s seeming inability to exit his lethargic condition, which they interpret as a symptom of the Russian status quo at the time of the Great Reforms. In the present article, I argue that the case of Oblomov demonstrates the limits of the civics’ mimetic criticism. The dominant chronotope of the novel, namely the idyll, indicates that Oblomov is not in essence a novel about the hero’s inability to change (which would presuppose …

Digital Public Library Ecosystem 2023, Rachel Noorda, Kathi Inman Berens

English Faculty Publications and Presentations

The Digital Public Library Ecosystem is the network of digital book collection and circulation specifically through public libraries. Digital book collection and circulation have never been more important than they are today. Nearly 1 in 3 Americans has read an ebook in the last 12 months. Audiobook listening is also high; nearly 1 in 4 Americans has listened to an audiobook in that same time period. Libraries are one way in which readers gain access to ebooks and audiobooks. Despite this, a holistic view of the digital library ecosystem is largely opaque. Three factors contribute to current confusion about the …

The Negative Stigma Surrounding Mathematics, Marissa A. Greisen

PSU McNair Scholars Online Journal

There is a negative stigma that surrounds mathematics in our education system. It is important to bring notice to this for the benefit of future students. There is a lot of research claiming that math is looked down on, but they do not answer why, or what we can do to fix it. Why is there a greater negative stigma around math and not other subjects? What roles to teachers, parents, and peers play in this stigma? In this article, I created a survey for people to answer questions regarding their opinion on math, who they believe typically does well …

Probability Distribution Fitting For Censored Data: A Practical Guide For Survival Analysis Of Nbi Data For Concrete Bridge Decks In Oregon, Asmaa Almeshaileh

Dissertations and Theses

Many sophisticated statistical models and analyses have been proposed to analyze datasets derived from the national bridge inventory (NBI). These objectives range from creating an understanding of the factors that drive the deterioration of bridge members to providing agencies with quantitative information for their maintenance and repair decisions. As these models become increasingly sophisticated and difficult to comprehend and implement, practicing engineers and owners are less likely to use them. Often, however, grouping data intuitively, for example, per a select structure type or condition rating and analyzing them using prescriptive statistics such as distribution fitting, does not only lie in …

The Establishment And Shaping Of The Education System And National Identity In Manchukuo, Tianyang Lei

Dissertations and Theses

This thesis studies the education system and national identity of Manchukuo the nationstate (1932-1945). In September of 1932, the Japanese army staged the "Mukden Incident," a bombing of a railway line near Shenyang that was used as a pretext for the invasion of Manchuria. Following the incident, the Japanese established the state of Manchukuo with the last emperor of China, Puyi, as its nominal head of state. The establishment of Manchukuo marked the beginning of Japan's aggressive expansion in Asia and its militarization of the region. It also marked the start of Japan's effective control over large portions of Northeast …

Energy Auction With Non-Relational Persistence, Michael Ramez Howard

Dissertations and Theses

As the current landscape for electric vehicles changes, options for remote charging are expanding to keep up. In the United States alone, sales of electric vehicles grew 85% from 2020 until hitting 450,000 units by the end of 2021. While these growing sales are encouraging, commercial charging stations have a long way to go before they are as ubiquitous as gasoline stations are today. The peer-to-peer energy auction helps fill the gap in underserved areas by allowing private homeowners to share their charging facilities with other electric vehicle drivers. The auction framework wraps existing charging outlets with a Cloud-connected microcontroller. …

Motivation To Collaborate: A Qualitative Exploration Of The Perspectives Of Service Providers On An Alternative First Response Program, Desiree' J. Duboise

Dissertations and Theses

Alternative first response programs have existed in the United States for decades, and the formation of these programs has increased across the country in light of public calls for non-police responses to emergency. Portland Street Response (PSR) is an alternative first response program located in Portland, Oregon. The program assists individuals experiencing mental health crises by providing unarmed response in non-violent situations that ordinarily would be responded to by armed police officers. In order for such programs to thrive, collaboration with other organizations is crucial. Service-providing organizations are uniquely prepared to collaborate with a program such as PSR due to …

Tidal Bed Stress Asymmetry And Sediment Transport In Estuaries, Austin Scott Hudson

Dissertations and Theses

Rivers and estuaries provide numerous ecological, economic, and cultural resources. The value of these resources is greatly influenced by sediment transport processes, which can be affected by human activities and climate variability. A key driver of sediment transport in tidal rivers and estuaries is tidal asymmetry of velocity and bed stress, which can manifest from both non-linear tidal interactions and linear interactions among astronomical tidal constituents.

In this study, an analytical framework is developed to examine and describe the dynamics of bed stress asymmetry in semidiurnal, diurnal, and mixed-tide estuaries (Chapter 1). While tidal velocity asymmetry has been previously analyzed, …

Forest Generating Functions Of Directed Graphs, Ewan Joaquin Kummel

Dissertations and Theses

A spanning forest polynomial is a multivariate generating function whose variables are indexed over both the vertex and edge sets of a given directed graph. In this thesis, we establish a general framework to study spanning forest polynomials, associating them with a generalized Laplacian matrix and studying its properties. We introduce a novel proof of the famous matrix-tree theorem and show how this extends to a parametric generalization of the all-minors matrix-forest theorem. As an application, we derive explicit formulas for the recently introduced class of directed threshold graphs.

We prove that multivariate forest polynomials are, in general, irreducible and …

Cognitive Engagement During Group Learning Activities In Chemistry Courses: An Analysis Of Student Discourse, Safaa Youssef El-Mansy

Dissertations and Theses

As educators, our goal is to help our students be successful, but in order to accomplish this, we need to understand what factors contribute to student success. One factor, small-group active learning, has been correlated to improved academic outcomes; however, the magnitude of this improvement can vary across different courses, different types of group work, and even across courses that use the same group work structure. Therefore, it is important to understand what aspects of group work contribute to its effectiveness. The work presented in this dissertation investigated one specific aspect: students’ cognitive engagement. This was done by analyzing the …

Beautifully Grotesque: Umezu Kazuo And The Shōjo Experience In Horror Manga, Miko Suzuki

Dissertations and Theses

"Mama's Scary" ("Mama ga kowai", 1965) by manga artist Umezu Kazuo took a new direction in depicting mother-daughter relationships by giving them a monstrous twist. "Mama's Scary" directly responded to how mother-daughter relationships were portrayed in 1960s shōjo manga, in which they were typically shown to be loving and caring, hence why adding horror elements to such relationship dynamics was considered jarring during the Shōwa era. Therefore, to analyze "Mama's Scary" is to also explore how women and young girls were portrayed in manga by men during the Shōwa era, and to analyze how adding the element of horror either …

Prosecutors Or Helpers: An Institutional Ethnography Of Child Protective Services Casework, Anna Maria Rockhill

Dissertations and Theses

The mission of child welfare is to strengthen the ability of families to care for their children and to protect children and provide aid, services, or referrals to families where maltreatment is said to have occurred. The vast majority of the families who become involved with child welfare are multiply disadvantaged and child welfare is a key feature of the array of public supports for struggling families. However, the institution fails many of the families it serves. Despite recent efforts by those in the field to promote collaboration and engagement, many parents experience child welfare as neither empowering nor helpful …

A Bayesian Network-Based Methodology For Improved Bridge Load Rating And Asset Management, Jeffery Mark Roberts

Dissertations and Theses

From the day a new structure is made available for use, to the day that the structure is no longer able to fulfill an intended purpose, structural safety is a vital interest. Managing a portfolio of structures can be a difficult undertaking for an asset manager, particularly if different types of structures are being maintained. The goal is to manage assets in the most efficient manner which can be influenced by, at a minimum, safety and financial concerns.

A potential tool for an asset manager or owner is the use of Bayesian Networks (BNs). When a BN is used to …

The Basic Dualism In The World, Martin Zwick

Complex Systems Faculty Publications and Presentations

Graham Harman writes that the “basic dualism in the world lies…between things in their intimate reality and things as confronted by other things.” This paper supports Harman’s assertion from a systems theoretic perspective and illustrates it with some examples, including conceptions about truth, ethics, value, and intelligence. But dualism implies irreconcilable difference; what Harman points to is better expressed as a dyad, where the two components not only imply one another but are related, and where this spatial dyad is usefully augmented with a temporal dimension, expressed in a third component or an additional orthogonal dyad.

Evaluation Of The Slip History And Holocene Activity Of The Strawberry Fault, Grant County, Oregon, Andrew Dunning

Dissertations and Theses

Lidar topographic data for the Strawberry Mountains, Oregon has revealed youthful fault scarps that likely result from Holocene-age earthquakes. We have mapped 27 km of fault scarps striking roughly east-west across the northern foothills of the Strawberry Mountains (Strawberry Fault, SBF) and another scarp lineament striking north-south along the uppermost John Day River 10 km to the south. SBF scarps are aligned with the bedrock John Day Fault, a reactivated Miocene structure that is accommodating distributed extension north of the Basin and Range region. The Strawberry Mountains sit near the interface of the extensional Basin and Range province to the …

Automating Intended Target Identification For Paraphasias In Discourse Using A Large Language Model, Alexandra C. Salem, Robert Gale, Mikala S. Fleegle, Gerasimos Fergadiotis, Steven Bedrick

Speech and Hearing Sciences Faculty Publications and Presentations

Purpose:

To date, there are no automated tools for the identification and fine-grained classification of paraphasias within discourse, the production of which is the hallmark characteristic of most people with aphasia (PWA). In this work, we fine-tune a large language model (LLM) to automatically predict paraphasia targets in Cinderella story retellings.

Method:

Data consisted of 332 Cinderella story retellings containing 2,489 paraphasias from PWA, for which research assistants identified their intended targets. We supplemented these training data with 256 sessions from control participants, to which we added 2,415 synthetic paraphasias. We conducted four experiments using different training data configurations to …

Private Benefits From Ambient Air Pollution Reduction Policies Evidence From The Household Heating Stove Replacement Program In Chile, Adolfo Uribe, Randall Bluffstone, Carlos Chávez, Walter Gómez, Marcela Jaime

Economics Faculty Publications and Presentations

We estimate the key private benefits from a program to improve ambient air quality during winter in central Chile by replacing inefficient wood-fired home heating stoves with more efficient pellet stoves. We are interested in the private benefits to households because they represent the additional value of the program and likely drive private adoption. Combining electronic stove surface temperature and air pollution monitoring with household surveys, we estimate the effects of adoption on household fuel expenditures, indoor temperatures, and indoor air pollution concentrations (PM2.5). We also explore heterogeneous effects of the program by income group and energy poverty status. Our …

Critical Analysis Of Anti-Asian Hate In The News, Benardo Douglas Relampagos

Dissertations and Theses

Since 2019, the United States has had an increase in violence against Asian American Pacific Islander (AAPI) communities along with an increase of mainstream anti-Asian racist rhetoric. Between 2021 and 2022, The Center for the Study of Hate & Extremism reported an overall 164% increase in anti-Asian hate crimes. While racism against black, Indigenous, people of color (BIPOC) communities has been the topic of an ever-growing body of critical discourse, prior to 2019 few publications had addressed racism and injustice regarding language choices and discourse in the context of anti-Asian rhetoric in the US, specifically regarding the intersection of language …
