Proceedings Of The Rust-Edu Workshop, Bart Massey

Rust-Edu Workshop

The 2022 Rust-Edu Workshop was an experiment. We wanted to gather together as many thought leaders we could attract in the area of Rust education, with an emphasis on academic-facing ideas. We hoped that productive discussions and future collaborations would result. Given the quick preparation and the difficulties of an international remote event, I am very happy to report a grand success. We had more than 27 participants from timezones around the globe. We had eight talks, four refereed papers and statements from 15 participants. Everyone seemed to have a good time, and I can say that I learned a …

Teaching Fisheries Bycatch: Exploring Economic And Behavioral Drivers Of Bycatch Through A Classroom Game, Mitch B. Priestley, J. Forrest Williams, Sahan Dissanayake

Economics Faculty Publications and Presentations

This paper presents a pedagogical exercise to explore the economics of price-based fisheries bycatch. In the exercise students experience the economic incentives that lead to bycatch due to highgrading; the discarding of low-value fish. We first discuss existing fisheries economics pedagogical activities and how our exercise is distinct. We then identify over forty economics, environmental studies, geography, management, and philosophy courses where the exercise could be played. Next, we describe the game and share results and student feedback. Finally, we provide discussion prompts and extensions to illustrate how incentives and policies can change fishing behavior to lead to sustainable fisheries.

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 …

Health Of Transgender Adults, 2020, Addie Furrer

University Honors Theses

Transgender and gender diverse individuals are known to experience barriers to accessing medical care while also being at higher risk of chronic conditions. In this study, the health conditions, disabilities, and health care access of 1,017 transgender and gender diverse(TGD) respondents to the 2020 Behavior Risk Factor Surveillance System were examined in relation to both cisgender men and cisgender women. This analysis was done to further the effort of understanding the health disparities experienced by TGD populations. Transgender and gender diverse individuals were more likely to have poor overall health and mental health, have multiple chronic health conditions, and have …

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 …

On Epidemiology As Racial-Capitalist (Re)Colonization And Epistemic Violence, Ryan J. Petteway

OHSU-PSU School of Public Health Faculty Publications and Presentations

This commentary reflects upon power-knowledge dynamics and matters of epistemic, procedural, and distributive justice that undergird epidemiological knowledge production related to racial health inequities in the U.S. Grounded in Foucault’s power-knowledge concepts—“objects”, “ritual”, and “the privileged”—and guided by Black feminist philosopher Kristie Dotson’s conceptualization of epistemic violence, it critiques the dominant positivist, reductionist, and extractivist paradigm of epidemiology, interrogating the settler-colonial and racial-capitalist nature of the knowledge production/curation enterprise. The commentary challenges epidemiology’s affinity for epistemological, procedural, and methodological norms that effectively silence/erase community knowledge(s) and nuance in favor of reductionist empirical representations/re-presentations produced by researchers who, often, have never …

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 …

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 …

C3ar Plays Both Sides In Regulating Resistance To Bacterial Infections, Jesse A. Corcoran, Brooke A. Napier

Biology Faculty Publications and Presentations

Activation of the complement pathway results in the production of bioactive C3a, a product of C3 cleavage, which interacts with membrane-bound receptor C3aR to regulate innate immune cell function and outcome of bacterial infection. Specifically, previous research has identified mechanistically distinct and cell type–specific roles for C3aR in regulating innate immune cell inflammatory state, antimicrobial killing capacity, and metabolism. Historically, the production of C3a has been relegated to the serum; however, recent studies have provided evidence that various cell types can produce intracellular C3a that stimulates intracellular C3aR. In light of these new results, it is imperative that we revisit …

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 …

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 …

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 …
