The purpose of this review is to highlight each of the characteristics of phonics instruction and whole language instruction and to evaluate …

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.

What Explains Male And Female Decision Making To Enter Law? Evidence From A Survey Of Us-Based Undergraduate Students, Abigail Cohen

University Honors Theses

The research conducted in this thesis aims to explain why fewer females than males choose law and pinpoint the explanation as to why they have disparate experiences in the field. The hypothesis is sex discrimination is to blame for the differences among female and male decision making. Sexual harassment and discrimination plays a very prominent role in male dominated fields and discourages females from joining those workforces. The research method for this experiment was an anonymous survey, sent out via social media and email. The survey method was chosen because it was meant to be a quick, yet effective way …

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 …

Wavelength-Induced Shedding Frequency Modulation Of Seal Whisker Inspired Cylinders, Trevor Dunt, Kirby S. Heck, Kathleen Lyons, Christin Murphy, Raul Bayoan Cal, Jennifer A. Franck

Mechanical and Materials Engineering Faculty Publications and Presentations

The spanwise undulated cylinder geometry inspired by seal whiskers has been shown to alter shedding frequency and reduce fluid forces significantly compared to smooth cylindrical geometry. Undulation wavelength is systematically investigated in order to explore its effect on unsteady lift force and shedding frequency. Prior research has parameterized the whisker-inspired geometry and demonstrated the relevance of geometric variations on force reduction properties. Among the geometric parameters, undulation wavelength was identified as a significant contributor to forcing changes. To analyze the effect of undulation wavelength, a thorough investigation isolating changes in wavelength is performed to expand upon previous research that parameterized …

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 …

A Qualitative Study On The Persistence Of Seasoned Student Affairs Professionals, Russell Taylor Jones

Dissertations and Theses

The attrition of student affairs professionals has plagued higher education for decades and continues to negatively impact the profession. Over 40% of new student affairs professionals leave the field and leading contributors to this departure include unsustainable working norms, outdated and deficient job-related incentives, and burnout. Prior research focused primarily on why staff intend to leave and do leave student affairs, but little research has explored why professionals persist and successfully cultivate a long-term, sustainable career in student affairs. The purpose of this study was to explore the experiences of seasoned student affairs professionals who have persisted in the field …

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, …

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. Specifically, this study involved six participants divided into two groups of DLBE teachers in the teaching trajectory: three Latine K-5 Spanish/English DLBE teachers currently teaching in …

The Arab Spring Uprisings In Geopolitical Context, Jake Alan Rutledge

Dissertations and Theses

The question of why revolts, civil wars, and social unrest occur is central in the field of political science. This paper asks that question in the specific context of the 2011 Arab Spring uprisings as a revolutionary wave. Many theories of revolution and social unrest locate their causes in the internal characteristics of the country where they take place, such as the country's demographics or level of economic development. This paper examines the external situation of a country: its relationships with other states and the international community. This paper examines eighteen Arab countries in the Middle East and North Africa …

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 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 …

Deep Structure Of Siletzia In The Puget Lowland: Imaging An Obducted Plateau And Accretionary Thrust Belt With Potential Fields, Megan L. Anderson, Richard J. Blakely, Ray E. Wells, Joe D. Dragovich

Geology Faculty Publications and Presentations

Detailed understanding of crustal components and tectonic history of forearcs is important due to their geological complexity and high seismic hazard. The principal component of the Cascadia forearc is Siletzia, a composite basaltic terrane of oceanic origin. Much is known about the lithology and age of the province. However, glacial sediments blanketing the Puget Lowland obscure its lateral extent and internal structure, hindering our ability to fully understand its tectonic history and its influence on modern deformation. In this study, we apply map-view interpretation and two-dimensional modeling of aeromagnetic and gravity data to the magnetically stratified Siletzia terrane revealing its …

Watershed, Lake, And Food Web Factors Influence Diazotrophic Cyanobacteria In Mountain Lakes, Lara Jansen, Daniel Sobota, Yangdong Pan, Angela Strecker

Environmental Science and Management Faculty Publications and Presentations

Cyanobacterial blooms can occur in freshwater ecosystems largely isolated from development and not experiencing extensive cultural eutrophication. For example, remote mountain lakes can experience intense blooms of diazotrophic (nitrogen-fixing) cyanobacteria caused by factors acting at different spatial and temporal scales. In this study, we examined how cross-scale interactions among watershed, lake, and food web characteristics influence diazotrophic cyanobacteria biovolume in mountain lakes. We quantified diazotrophic cyanobacteria biovolume, zooplankton abundance, and physico-chemical variables for 29 lakes in the Cascade Mountains of Oregon, USA, in summer 2019. Watershed characteristics were compiled from historical datasets available for the region. Diazotrophic cyanobacteria biovolume ranged …

Judgment, Shame, And Coercion: The Criminal Legal System And Reproductive Autonomy, Ginny Garcia-Alexander, Melissa Thompson

Sociology Faculty Publications and Presentations

Background

A growing body of research has called attention to limitations to reproductive autonomy in both women who are socially disadvantaged and in those who have had contact with the criminal legal (CL) system. However, it is unclear whether CL system contact influences contraceptive use patterns and how these processes unfold. We utilize a mixed-methods approach to investigate whether history of arrest is associated with receipt of contraceptive counseling, use of long-term contraception, sterilization, and subsequent desire for reversal of sterilization. We further consider how agents in and around the CL system may influence women’s reproductive decisions and outcomes (856 …

Active Transportation Counts From Existing On-Street Signal And Detection Infrastructure, Sirisha Kothuri, Patrick Allen Singleton, Mahyar Vahedi Saheli, Elizabeth Yates, Joseph P. Broach

Civil and Environmental Engineering Faculty Publications and Presentations

This study’s objective was to use data from existing traffic signal infrastructure to estimate pedestrian volumes. Pedestrian push-button actuations were collected from signal controller logs at 49 intersections in western Oregon and an additional 16 intersections in eastern Oregon. These actuations were then compared to observed pedestrian counts, totaling over 34,000 people, obtained from video recordings. After exploring various options, a simple quadratic relationship was modeled using a single measure of pedestrian signal activity: the number of push-button presses (filtered to remove multiple presses within 15 seconds). The model’s predictions showed a correlation of 0.86 with observed pedestrian volumes and …

Oral Health And Older Adults: A Narrative Review, Martin S. Lipsky, Tejasvi Singh, Golnoush Zakeri, Man Hung

Institute on Aging Publications

Oral health’s association with general health, morbidity, and mortality in older adults highlights its importance for healthy aging. Poor oral health is not an inevitable consequence of aging, and a proactive, multidisciplinary approach to early recognition and treatment of common pathologies increases the likelihood of maintaining good oral health. Some individuals may not have regular access to a dentist, and opportunities to improve oral health may be lost if health professionals fail to appreciate the importance of oral health on overall well-being and quality of life. The authors of this narrative review examined government websites, the American Dental Association Aging …

Ubiquitous Filter Feeders Shape Open Ocean Microbial Community Structure And Function, Anne W. Thompson, Györgyi Nyerges, Kylee M. Brevick, Kelly Sutherland

Biology Faculty Publications and Presentations

The mechanism of mortality plays a large role in how microorganisms in the open ocean contribute to global energy and nutrient cycling. Salps are ubiquitous pelagic tunicates that are a well-known mortality source for large phototrophic microorganisms in coastal and high-latitude systems, but their impact on the immense populations of smaller prokaryotes in the tropical and subtropical open ocean gyres is not well quantified. We used robustly quantitative techniques to measure salp clearance and enrichment of specific microbial functional groups in the North Pacific Subtropical Gyre, one of the largest ecosystems on Earth. We discovered that salps are a previously …
