Localized Eigenvectors On Metric Graphs, Hannah Kravitz, Moysey Brio, J G, Caputo

Mathematics and Statistics Faculty Publications and Presentations

We analyze the eigenvectors of the generalized Laplacian for two metric graphs occurring in practical applications. In accordance with random network theory, localization of an eigenvector is rare and the network should be tuned to observe exactly localized eigenvectors. We derive the resonance conditions to obtain localized eigenvectors for various geometric configurations and their combinations to form more complicated resonant structures. These localized eigenvectors suggest new indicators based on the energy density; in contrast to standard criteria, ours provide the number of active edges. We also suggest practical ways to design resonating systems based on metric graphs. Finally, …

The Mosaic Programs Of The Basilica Of San Vitale And The Great Palace Of Constantinople: A Unique Reinvention Of Roman Pasts, Justine Spencer

University Honors Theses

The Church of San Vitale and the Great Palace of Constantinople offer remarkable examples of artistic productions in early Byzantine mosaics. Bridging from the same Roman past they reinvented a classical medium with their unique interpretations of earlier traditions. They exemplify the diversity of Byzantine artistic productions that could coexist within the same medium and era. The mosaics of the Great Palace were part of a secular governmental public space and found deep in the heart of the Eastern Roman Empire. The mosaics of the Church of San Vitale were made for the domain of the newly reconsecrated Orthodox church …

Nonlinear Interactions Of Sea‐Level Rise And Storm Tide Alter Extreme Coastal Water Levels: How And Why?, H. Moftakhari, D. F. Muñoz, A. Akbari Asanjan, A. Aghakouchak, Hamid Moradkhani, David A. Jay

Civil and Environmental Engineering Faculty Publications and Presentations

Sea-level rise (SLR) increasingly threatens coastal communities around the world. However, not all coastal communities are equally threatened, and realistic estimation of hazard is difficult. Understanding SLR impacts on extreme sea level is challenging due to interactions between multiple tidal and non-tidal flood drivers. We here use global hourly tidal data to show how and why tides and surges interact with mean sea level (MSL) fluctuations. At most locations around the world, the amplitude of at least one tidal constituent and/or amplitude of non-tidal residual have changed in response to MSL variation over the past few decades. In 37% of …

Methods:We implemented an adolescent peer-based text messaging intervention to encourage clinic attendance …

Gestural Temporality In Sciarrino’S Recitativo, Antares L. Boyle

School of Music + Theater Faculty Publications and Presentations

Sciarrino’s writings describe a compositional philosophy that prizes multidimensionality and spatiotemporal discontinuity (1998, 2004). Yet his simultaneous allegiance to teleology, holism, and fractal hierarchies reveals an underlying unifying organicism with which these qualities may initially seem to conflict. I take Sciarrino’s 1999 piano concerto Recitativo oscuro as a case study for examining the composer’s gestural organicism and its various contradictions and double meanings. First, close analysis of the opening piano solo demonstrates how seemingly contradictory aesthetic priorities—organic unity and temporal multiplicity—co-exist within a single passage. Drawing from Kramer’s (1988) concept of “gestural time,” Hatten’s (2004) theory of gesture, segmentation theories, …

Uncovering The Critical Drivers Of Blockchain Sustainability In Higher Education Using A Deep Learning-Based Hybrid Sem-Ann Approach, Mohammed Alshamsi, Mostafa Al-Emran, Tugrul Daim, Mohammed A. Al-Sharafi, Gulin Idil Sonmezturk Bolatan, Khaled Shaalan

Engineering and Technology Management Faculty Publications and Presentations

The increasing popularity of Blockchain technology has led to its adoption in various sectors, including higher education.

Based on 374 valid responses collected from university students, the proposed model is evaluated through a deep learning-based hybrid structural equation modeling (SEM) and artificial neural network (ANN) approach. The PLS-SEM results confirmed most of the hypotheses in the proposed model. The sensitivity …

Inclusive Postsecondary Education's Effect On Individuals With Idd: A Systematic Literature Review, Hunter Wolff

University Honors Theses

With the purpose of evaluating the impact of Inclusive Postsecondary Education (IPSE) effects on those experiencing intellectual and/or developmental disabilities (IDD), a systematic literature review was conducted. Proponents of the expansion of these programs often cite participant growth in academic-related skills, socialization, and competitive integrated employment. While several studies document these benefits, few studies present and discuss all the data collectively. This review aims to both locate the data that shows how IPSE programs affect the students within them as well as to provide a location in which all the data can be accessed. A thorough conducting of the research …

Death, Grief, And Loss Through The Eyes Of Child: The Importance Of Teaching Children About Death Using Children's Literature, Sara Holzschuh

University Honors Theses

This thesis will explore how we view death as a death-denying society, along with the importance of teaching children about death and grief early on in their lives. When talking to children about death it is critical to refrain from abstract language and instead use death-specific language. Children need to understand that death is a universal experience, that death is irreversible, and that the body ceases all life functions at the time of death. This thesis will also discuss avenues for teaching children about death and argues that picture books are a fantastic way of introducing children to death. It …

Unlocking Potential: The Transformative Power Of Trauma-Informed Schools On Students' Well-Being And Academic Success, Tiffany Carolino

University Honors Theses

Trauma-informed approaches in public schools have emerged as a promising strategy to address students' social-emotional well-being and academic success impacted by adverse childhood experiences (ACEs). This paper explores the necessity and effectiveness of trauma-informed practices within educational settings. Adverse childhood experiences encompass a range of traumatic events that profoundly affect children's development, behaviors, and academic performance. Despite the prevalence of ACEs, traditional disciplinary practices often fail to address the underlying issues, leading to further challenges for students. This literature review examines three trauma-informed programs: HEARTS, TIES, and STRIVE, each offering strategies to support students and educators. Results from these programs …

Psilocybin With Acceptance And Commitment Therapy (Act) For The Treatment Of Social Anxiety Disorder (Sad), Aspen E. Allred

University Honors Theses

Social Anxiety Disorder (SAD) is a debilitating mental health condition characterized by an overwhelming fear and anxiety of social rejection that can lead to chronic patterns of social behavioral avoidance. Despite the existence of traditional efficacious treatments, a significant number of individuals either do not respond to treatment or experience a recurrence of symptoms over extended periods, spanning 10-12 years. Acceptance and Commitment Therapy (ACT), a form of acceptance-based behavioral therapy considered part of the "third wave" of cognitive behavioral therapies, has shown promising results in early studies, comparable to those of Cognitive Behavioral Therapy (CBT) that is considered the …

Providing Incarcerated Youth With A Community Of Their Peers, Providing Resources, And Modeling Healthy Attachment May Lead To Prosocial Behaviors, Emilee Brnusak

University Honors Theses

This thesis examines the connection between gang activity and attachment style. A summary of literature suggests that childhood attachment injuries lead to antisocial, maladaptive relationships and neurological changes that impact executive functioning and emotional regulation. These factors leave youth at higher risk of gang membership. This thesis then explores how an outreach experience at the MacLaren Youth Correctional Facility inspired a large-scale intervention called Resources for Attachment-injured Youth (RAY) that could be implemented in youth prisons across the country.

An Evaluation Of The Federal Transition Incentives Program On Land Access For Next-Generation Farmers, Megan Horst, Julia Valliant, Julia Freedgood

Urban Studies and Planning Faculty Publications and Presentations

Next-generation farmers face immense challenges in securing land. In recent years, some state- and federal-level land access policy incentives (LAPIs) have been implemented to address these chal­lenges. In this paper, we assess the Transition Incentives Program (TIP), an initiative of the U.S. Department of Agriculture’s Conservation Reserve Program that is funded by Congressional farm bills. TIP offers landowners two years of financial incen­tives for leasing or selling to a beginning or socially disadvantaged farmer or rancher (categories of farmers defined by the U.S. Department of Agri­culture). In our study, we characterize TIP partici­pants to understand where and how TIP assists …

Primary Care As A Protective Factor: A Vision To Transform Health Care Delivery And Overcome Disparities In Health, Edward L. Machtinger, Alicia F. Lieberman, Christina D. Bethell, Marguerita Lightfoot

OHSU-PSU School of Public Health Faculty Publications and Presentations

A large body of research demonstrates that experiences of trauma, especially when they occur in the absence of safe, stable, nurturing relationships (SSNRs) and environments— known as protective factors— interrupt healthy development and predispose both children and adults to the most common causes of physical and mental illness and early death.1,2 Because minoritized and low-income populations are exposed to more trauma and have access to fewer protective factors, they experience higher rates of trauma-related health and social problems and severe disparities in health.1–4 Primary care clinicians increasingly recognize the role that trauma plays in the health and well-being of their …

Drawing on classwork and interview responses, this …

It Takes A Village: An Examination Of Social Relationships And Mental Health, Em Francis Trubits

Dissertations and Theses

Social relationships are impactful to mental health and well-being, both positively and negatively. Different sources of support vary in their ability to meet our needs and ultimately influence our well-being. While research has examined aspects of supportive and harmful social relationships and mental health, much of this work is cross-sectional or limited to a single source of support. This dissertation aimed to better elucidate the relationship between social relationships and mental health by integrating multiple theoretical perspectives and multiple sources of support, in a series of three empirical studies in order to inform theory and interventions targeting mental health of …

The Mirror Project: Reflections On The Experiences Of African-American Female Adolescents Experiencing Foster Care, Bahia Anise-Cross Degruy Overton

Dissertations and Theses

As the author Zora Neale Hurston says, "If you're silent about your pain, they'll kill you and say you enjoyed it." The Mirror Project (MP) aims to break this silence by giving voice to Black women who have experienced foster care in Portland, Oregon during their adolescence. In focus groups and interviews, participants shared their stories. Racial identity development theory, phenomenology and Afrocentric feminist epistemology provided lenses for gaining insight into their experiences in a predominantly white city. The MP revealed six themes: lack of youth engagement in foster care decisions, the need for a cultural lens in social work, …

Latine Dual Language Bilingual Education Teachers' Work Experiences, Nelly Noemi Patiño Cabrera

Dissertations and Theses

Given the increasing concern about the scarcity of Dual Language Bilingual Education (DLBE) teachers, it is crucial to understand the trends in teacher retention and attrition from the perspective of DLBE teachers themselves. DLBE teachers departing from their jobs imposes a significant burden on schools and students and affects the implementation of DLBE programs. To delve into this issue, this critical qualitative study focused on the work experiences of Latine K-5 Spanish/English DLBE teachers.

Persona Journey Mapping To Drive Equity During An Lms Transition, Kam Moi Lee, Kari Goin Kono, Megan Mcfarland

Office of Academic Innovation Publications

Technology systems that support learning–such as Learning Management Systems, or LMS’s–can change frequently in higher education. This often creates significant challenges for faculty-support staff during a transition–or migration–period. When equitable practice is deprioritized during these migrations, there is a high chance that stakeholders will experience adoption resistance, putting the project’s success and subsequent student experience at risk. Using a vignette and case study qualitative methodological approach, three researchers at a large urban university in the Pacific Northwest detail personas and journey mapping as an equitable design practice during a LMS migration on a rapid development timeline. This paper details how …

Mmwave Rat Optimization: Mac Layer Initial Access Design And Transport Layer Integration, Suresh Srinivasan

Dissertations and Theses

MmWave Radio Access Technology (RAT) is a promising technology for wireless communication due its large bandwidth and is already being deployed in 5G cellular and emerging WiFi technologies. MmWave systems use highly directional beams with narrow beamwidths to overcome the high path loss associated with their frequency bands. A mmWave radio can be used either in a standalone mode (where all radios use the same technology) or simultaneously with other technologies such as LTE and low frequency WiFi in a communication mode commonly referred to as integrated mode. This thesis proposes two methods to optimize mmWave RAT performance in both …
