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 …

System Dynamics Modeling For Traumatic Brain Injury: Mini-Review Of Applications, Erin S. Kenzie, Elle L. Parks, Nancy Carney, Wayne Wakeland

Complex Systems Faculty Publications and Presentations

Traumatic brain injury (TBI) is a highly complex phenomenon involving a cascade of disruptions across biomechanical, neurochemical, neurological, cognitive, emotional, and social systems. Researchers and clinicians urgently need a rigorous conceptualization of brain injury that encompasses nonlinear and mutually causal relations among the factors involved, as well as sources of individual variation in recovery trajectories. System dynamics, an approach from systems science, has been used for decades in fields such as management and ecology to model nonlinear feedback dynamics in complex systems. In this mini-review, we summarize some recent uses of this approach to better understand acute injury mechanisms, recovery …

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 …

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 …

The Impact Of The Covid-19 Pandemic On Mental Health And Stressors Among Asian American And Pacific Islanders, Ava Lu Kupperman

University Honors Theses

The Asian American and Pacific Islander (AAPI) community, along with the rest of the population globally, has been facing disruptions emerging from the COVID-19 pandemic in all parts of life. However, with the significant rise in racism, the AAPI community has had to confront a set of new challenges in their lives. Utilizing studies and literature written over the course of the pandemic, the purpose of this literature review is to examine the impacts observed on mental health outcomes among AAPIs as a result of the COVID-19 pandemic. This paper aims to collect and present information surrounding the impact on …

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 …

Gender Differences In Parental Leave Before And After The Introduction Of A Paid Parental Leave Policy: A Sequence Analysis Of Administrative Time-Keeping Records, Julia M. Goodman, Lisset Dumet Poma, David Hurtado, Anna Steeves-Reece, Dawn M. Richardson

OHSU-PSU School of Public Health Faculty Publications and Presentations

Paid leave confers health benefits to new parents and their children, but the absence of a national paid family leave policy in the United States has left workers to navigate a patchwork of paid and unpaid parental leave benefits accessed through their employers. As public and private paid leave policies expand across the US, it is imperative to determine how these benefits impact leave taking behaviors among new parents. We use sequence and cluster analyses of administrative time-keeping records to detail parental leave-taking during the first 180 days after adding a child among employees of a large public-sector organization with …

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 …

Monetizing Attention And Branding Strategy: Assessing The Effects Of Personal Branding On Amateur Athletic Compensation, Abby Christiansen

University Honors Theses

What role does branding play in the compensation issues faced by amateur athletes? How has the rise of influential online social personas legally impacted their case? This thesis explores the long-standing compensation issues that many amateur athletes have faced while under the control of the NCAA. It connects the social impact of online personal branding to some of the legal victories won by student athletes as they gain more freedom over their NIL (name, image, likeness) by detailing the importance of branding and its evolution into personal branding in a 21^st century economy. Many of the rules and regulations …

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 …

Feminist Care Ethics Confronts Mainstream Philosophy, Maurice Hamington, Maggie Fitzgerald

Philosophy Faculty Publications and Presentations

Editorial for the Special Issue "Feminist Care Ethics Confronts Mainstream Philosophy"

This Special Issue of Philosophies is devoted to dialogue between feminist care ethics and mainstream philosophical figures and concepts. As care ethics has evolved from its origins in the 1980s, it is clear that it does not always fit neatly within traditional philosophical categories. Yet, the philosophical implications of the ethics of care are robust and extend beyond ethics as such, with care theorists positing ontological, epistemological, and political significance to its approach. Despite these implications, and the growing acceptance of care ethics in a variety of academic literatures, …

Building Community Capacity With Philosophy: Toolbox Dialogue And Climate Resilience, Bryan Cwik, Chad Gonnerman, Michael O'Rourke, Brian Robinson, Daniel Schoonmaker

Philosophy Faculty Publications and Presentations

In this article, we describe a project in which philosophy, in combination with methods drawn from mental modeling, was used to structure dialogue among stakeholders in a region-scale climate adaptation process. The case study we discuss synthesizes the Toolbox dialogue method, a philosophically grounded approach to enhancing communication and collaboration in complex research and practice, with a mental modeling approach rooted in risk analysis, assessment, and communication to structure conversations among non-academic stakeholders who have a common interest in planning for a sustainable future. We begin by describing the background of this project, including details about climate resiliency efforts in …

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 …

Multi-Method Investigation Of Factors Influencing Amyloid Onset And Impairment In Three Cohorts, Tobey J. Betthauser, Murat Bilgel, Rebecca L. Koscik, Bruno Jedynak, Yang An, Kristina A. Kellett, Abhay Moghekar, Erin M. Jonaitis, Charles K. Stone, Multiple Additional Authors

Mathematics and Statistics Faculty Publications and Presentations

Alzheimer’s disease biomarkers are becoming increasingly important for characterizing the longitudinal course of disease, predicting the timing of clinical and cognitive symptoms, and for recruitment and treatment monitoring in clinical trials. In this work, we develop and evaluate three methods for modelling the longitudinal course of amyloid accumulation in three cohorts using amyloid PET imaging. We then use these novel approaches to investigate factors that influence the timing of amyloid onset and the timing from amyloid onset to impairment onset in the Alzheimer’s disease continuum.

Data were acquired from the Alzheimer’s Disease Neuroimaging Initiative (ADNI), the Baltimore Longitudinal Study of …

Perceived Stress, Resilience, And Wellbeing In Seasoned Isha Yoga Practitioners Compared To Matched Controls During The Covid-19 Pandemic, Preeti Upadhyay, Shilpa Narayanan, Tanvi Khera, Lauren Kelly, Pooja A. Mathur, Akshay Shanker, Lena Novack, Ruth Pérez-Robles, Kim A. Hoffman, Multiple Additional Authors

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Yoga practices, including breathing, meditation, and posture protocols (asanas), have been shown to facilitate physical and mental wellbeing.

Methods: Seasoned yoga practitioners were recruited from the Isha Foundation. Recruitment of the comparison group was achieved using snowball sampling and were not yoga practitioners. Participants in the non-yoga group were randomized to a 3-min Isha practice or a comparator group asked to perform 15-min of daily reading. Participants completed a series of web-based surveys (REDCap) at baseline, 6, and 12 weeks. These surveys include validated scales and objective questions on COVID-19 infection and medical history. The validated questionnaires assess for: …

Leaving College Without A Degree: The Student Experience At An Urban Broad Access Institution, Andrea Marie Garrity

Dissertations and Theses

This thesis seeks to understand how students who leave college without a degree, or non-completers, experience broad access institutions in an effort to shift our thinking from the student characteristics that predict college dropout to how broad access institutions can better serve students and improve graduation rates. To answer this question, I conducted interviews with former students who had recently attended a broad access institution and left without a degree. Results show that participants expressed internalized views of the traditional college student archetype, which was reinforced through their college experience. Further, participants encountered significant bureaucratic challenges and barriers, and expressed …

Examining Demographic And Environmental Factors In Predicting The Perceived Impact Of Cancer On Childhood And Adolescent Cancer Survivors, Nazan Cetin

Dissertations and Theses

Cancer survivors' perceptions on how cancer has impacted their lives has been identified as a "critical predictor" of psychosocial well-being and quality of life outcomes. Given the dramatic increase in survival rates and the long-term health and psychosocial challenges, as well as survivorship care barriers, this study focuses special attention on childhood and adolescent cancer survivors and is guided by Tedeschi and Calhoun's theory of posttraumatic growth and Hammond's theory of distinctiveness. This study aims to examine the influence of demographic (i.e., age at diagnosis, biological sex, race/ethnicity, type of cancer) and environmental factors (i.e., geographical location and insurance type), …

Knowledge Overconfidence Is Associated With Anti-Consensus Views On Controversial Scientific Issues, Nicholas Light, Philip M. Fernbach, Nathaniel Rabb, Mugur V. Geana, Steven A. Sloman

Business Faculty Publications and Presentations

Public attitudes that are in opposition to scientific consensus can be disastrous and include rejection of vaccines and opposition to climate change mitigation policies. Five studies examine the interrelationships between opposition to expert consensus on controversial scientific issues, how much people actually know about these issues, and how much they think they know. Across seven critical issues that enjoy substantial scientific consensus, as well as attitudes toward COVID-19 vaccines and mitigation measures like mask wearing and social distancing, results indicate that those with the highest levels of opposition have the lowest levels of objective knowledge but the highest levels of …

A Pilot Study Considering Ecoroofs As Therapeutic Landscapes, Olyssa Starry, Arjun Viray, Brenna Park-Egan, Amber Terway, Timothy Oxendahl, Tina Dawn Lillian Burdsall

Sociology Faculty Publications and Presentations

The potential for urban open spaces to convey therapeutic benefits is increasingly substantiated. More work is needed to specifically consider how low impact designs to manage stormwater such as ecoroofs perform in this context. Here, we report on a pilot study addressing: (1) factors determining whether a hospital has an ecoroof, and (2) how ecoroofs might convey therapeutic benefits. We utilized a mixed methods approach which encompassed phone interviews of hospital ecoroof managers as well as analysis of national hospital databases. We also conducted a local case study which compared cortisol samples and stress indicators from patients, staff, and caregivers …

A Day Late And A Dollar Short: Examining Perceptions Of Which Exonerees Deserve Compensation, Alexandra Pauline Olson

Dissertations and Theses

Many exonerees do not receive compensation from the state after they are found innocent and released because most states have exclusionary laws that bar exonerees from receiving compensation. This thesis examined public perceptions of exclusionary laws and addressed the broader question of who deserves compensation (according to community members). Online participants (n = 225) read an article about a fictional exoneree who either pleaded guilty or was convicted by a jury trial and who received a subsequent conviction or did not receive a subsequent conviction. An exoneree with a subsequent conviction was perceived as less deserving of financial compensation, …

Analyzing Classroom Discourse To Investigate Structuring Equitable Mathematical Talk In Small Groups And Whole-Class Discussions, Brittney Marie Ellis

Dissertations and Theses

Shifting classroom discourse to be more student-centered has become an integral part of reform-oriented instructional practices. At the same time, shifting discourse can open up opportunities for inequity to occur in the immediate learning environment as both the quantity and quality of mathematical talk changes. In this project, I examined complexities involved in such settings by using discourse analysis methods to explore the positioning of students relative to mathematics content and each other's mathematical ideas. First, I analyzed the ways teachers' discourse during group work enactments related to established equitable teaching practices. Findings from this study suggest communicating group tasks …

When The Lion Learns To Write: A Counterstory About A Doctoral Student's Qualitative Research Project, Martín Alberto Gonzalez

Chicano/Latino Studies Faculty Publications and Presentations

This essay utilizes critical race theory composite counterstorytelling to tell a story about Alberto, a first-generation Xicano doctoral student who is presenting his dissertation research proposal to his qualitative research class. Through Alberto’s character, I discuss my complicated process of designing and conducting a research study. Specifically, I reflect on why I decided to study the experiences of Mexican, Mexican American, and Xicanx students in higher education, why I used critical race theory, Latinx/a/o critical race theory, and critical race spatial analysis as theoretical frameworks, why I utilized critical collaborative ethnography as my research approach, and why I chose counterstorytelling …

Gender Equity And State-Mosque Relations In Middle East North Africa: A Case Study Of Tunisia, Joy Amarachi Agbugba

Dissertations and Theses

Why is the Middle East North Africa region consistently ranked the lowest on the gender equity scale? This question is quite perplexing and that has driven several scholarly researchers to investigate the situation of gender and women's rights within the states in the region. In this research, I explore the various theories explaining the cause of gender inequity in this region including the Islam thesis/social modernization theory, political-economic theory, and psychological/social structural theories, with an emphasis on the Islamic thesis theory. I argue that the state's support and prioritization of Muslim/sharia law over federal law is a major contributor to …

"Damn, Man. The Time That I Lost": Power And The Process Of Diagnosis For Women With Chronic Illnesses, Kaitlin Roquel Yeomans

Dissertations and Theses

Historical sociological research on people with chronic illness has examined their navigation of their lives post-diagnosis. Diagnosis has been considered with regard, not to its process, but rather to its definitions. While a rich literature has been produced by such approaches, how people experience the process of diagnosis has largely been ignored. This research looks at the process of diagnosis as a series of moments, all of which hold specific meaning in the interactional context of the patient-provider relationship. Looking at diagnosis from the patient’s perspective demonstrates how information about health and illness is exchanged, navigated, and negotiated. Importantly, this …

A Critical Discourse Analysis Of How Youth In Care Describe Social Support, Jared Israel Best

Dissertations and Theses

There are nearly 422,000 youth in foster care in the United States with 20,000 aging out each year. Youth who age out of care demonstrate worse outcomes in all areas (education, employment, homelessness, justice system involvement, and social support) compared to the general population. These outcomes represent an ideological production, or a production of knowledge regarding the discursive youth in care. Thus, dominant discourses of youth are informed and constitutive of these problematic outcomes. Similarly, youthhood is dominantly defined by risk and informed by peer groups and social relationships. This study presents findings from interviews with 22 youth preparing to …

Legislative Procedures And Perceptions Of Legitimacy, Megan Elizabeth Cox

Dissertations and Theses

While mechanisms of legitimacy development have been extensively studied in governments as a cohesive whole, procedural legitimation of the legislative branch has not been explored. Using a procedural justice framework to identify indicators of openness in legislative rules, this paper theorizes that the presence or absence of these indicators will be the key factor in public perceptions of legitimacy of the legislature. This paper hypothesizes that where more indicators are present, a legislature will be viewed as more legitimate by its citizens as compared to a legislature with fewer indicators.

Comparing Indonesia and the Philippines, two presidential democracies in Southeast …

Family-Supportive Supervisor Behaviors And Psychological Distress: A Secondary Analysis Across Four Occupational Populations, Philip G. Bouleh, Shalene Joyce Allen, Leslie Hammer

Psychology Faculty Publications and Presentations

This study assessed the associations of employee’s perceptions of family-supportive supervisor behaviors (FSSB) and their psychological distress across four occupational populations (n = 3778): Information technology; healthcare; military-connected Veterans; and National Guard service members. Data were gathered and analyzed from four larger archival datasets to compare differences in these relationships. Results revealed significant negative relationships between employee reports of FSSB and their psychological distress within occupations, as expected. Furthermore, results revealed significant differences across occupational populations for employee reports of both FSSB and psychological distress. Hierarchical moderated multiple regression analyses were conducted to examine the extent of these mean differences …
