Under The Influence Of Parents: A Longitudinal Study Of Children’S Walking, Kyu Ri Kim

Student Research Symposium

Researchers have studied children's active travel; however, they have mostly been cross-sectional studies dealing with commuting to school and parental attitudes. To find ways to promote children's active travel, this longitudinal study uses panel data (two time periods) to examine how parents' actual walking and safety perception correlated with children’s walking. Using data from 240 children aged 4-16 and their parents in Portland, Oregon, we estimated a cross-lagged panel model (CLPM) to analyze the continuous relationships. We found that parents with more positive attitudes toward their walking walked more, and their children also walked more in both periods. In addition, …

Exploring Decolonial And Indigenous Mental Health Framework And Practice To Address Complex Trauma Among Palestinian Youth Living Under Violence Of Settler-Colonialism, Vivian L. Duong, Corrin Murphy

OHSU-PSU School of Public Health Annual Conference

The growing settler colonial project of Israel forced indigenous Palestinians to flee from their homeland to further the Zionist movement of establishing a Jewish-majority state. The forced dispossession and displacement of Palestinians at this time was referred to as the Nakba, or catastrophe (Masalha, 2002). From 1947 and 1949, approximately 750,000 Palestinians from a population of 1.9 million were made refugees (Al Jazeera, 2017). Also referred to as the ethnic cleansing of Palestine, Zionists forcibly took over 78 percent of Palestine, destroyed about 530 villages and cities, and killed around 15,000 Palestinians including more than 70 massacres (Al Jazeera, 2017). …

Menstruation Products And Perceptions: Breaking Through The Crimson Ceiling, Ava Colleran

Young Historians Conference

This paper examines different views on menstruation throughout history and their effects on social, political, and economic landscapes. The ancient Greeks, Romans, and Mayans all believed in the supposed ‘magical powers’ of menstrual blood. These societies held their own ideas on the limits of these magical abilities, and the good and evil forces they could be used for. Throughout these ancient societies, menstruation was used as a justification for the increased control of the state and men over women’s bodies. If menstrual blood did have these magical powers, it was a power that needed to be limited and controlled so …

Beyond The Bmi: Expanding Quantitative Methods To Study Health For All Bodies, Kieran Chase, Daniel Oron

OHSU-PSU School of Public Health Annual Conference

The public health field is beginning to reckon with its role in perpetuating and reinforcing systemic anti-fatness. Emerging evidence for the devastating health impacts of stigma call into question decades of research and policy that labels the size of people’s bodies as diseased. However, even as we acknowledge the harmful effects of stigma, the field is materially and institutionally invested in a health paradigm that centers weight loss and size-related proxies for health, such as the BMI. Public health scholars interested in questions related to nutrition, chronic disease, and exercise must begin to expand their research focus to imagine non-stigmatizing …

(Un)Weighted Assumptions: Anti-Fatness & Health, Kieran Chase, Nell Carpenter, Madysen Schreiber

OHSU-PSU School of Public Health Annual Conference

This lecture/discussion session aims to expand and add nuance to public health students’, professors’, and practitioners’ understanding of the interplay between body size and health. We will begin by naming and challenging common assumptions about the relationship between bodyweight and health outcomes. We will then argue for the consideration of weight-related stigma as a Fundamental Cause of Disease as defined by Phelan and Link, and for institutionally embedded anti-fat bias at the policy level (e.g., insurance policy, medical equipment) as a cause of population health inequity as defined in Whitehead’s Health Equity Framework. We offer these frameworks in contrast to, …

Investing In Family Planning, Education, And Empowering Of Women And Girls To Mitigate The Impact Of Climate Change: An Exemplary Case Of Rwanda., Adjoa N. Manu

OHSU-PSU School of Public Health Annual Conference

Countries where population growth is high are often highly impacted by the climate crisis despite not being a significant contributor to historical greenhouse gas emissions. This has created a global inequality in that countries with poorly developed infrastructure are 15 times more likely to have deaths due to climate related disasters such as floods, droughts, and storms compared to wealthy countries that can better protect against similar events. While the climate crisis impacts everyone, women and girls are at a higher risk because of their unique health needs and roles in the community. The effects of climate change can be …

Impact Of Industrial Disasters On The Mental Health Of Vietnamese Americans On The Gulf Coast, Vivian L. Duong

OHSU-PSU School of Public Health Annual Conference

An explosion on the Deepwater Horizon oil rig caused 200 million gallons of crude oil to spill on the Gulf Coast over a five-month span. About 16,000 miles of coastline, ecosystem and marine life along Alabama, Florida, Louisiana, Mississippi, and Texas were contaminated. This disaster and the recovery process caused social, financial, and ecological shocks, resulting in adverse psychosocial and physical health outcomes, health disparities, and socioeconomic inequality. Among the oil spill's most affected and vulnerable populations are the Vietnamese American communities that settled on the Gulf Coast after the end of the Vietnam War in 1975. The plight of …

Farmworker Voices: Contesting & Renegotiating Essential Status During The Covid-19 Pandemic, Jennifer Martinez

Student Research Symposium

This study draws on a subset of thirty individuals that took part in the community-driven Oregon COVID-19 Farmworker Study to analyze how farmworkers interpreted the contradictory label essential worker. Using discourse analysis, this article examines how these peasant workers drew on their embodied experiences working throughout the pandemic to give meaning to their essential designation. The data suggest that farmworkers were tacitly aware of the contradictions between their labeling as indispensable and their disposable treatment on the ground. Farmworkers generally felt unrecognized, underpaid, and felt exposed to COVID-19 infection in addition to everyday workplace hazards. While the essential title was …

Third-Wave, Mindfulness-Based Therapies As Treatments For Obsessive-Compulsive Disorder: A Randomized Controlled Trial, Xander Kahle, Avery Waklatsi, Amy Pytlovany

Student Research Symposium

Obsessive-compulsive disorder (OCD) is a severe, difficult-to-treat neuropsychiatric condition that affects millions of people throughout the world. The current first-line psychotherapy for OCD is exposure and response prevention (ERP). ERP is effective but flawed, and researchers seek alternative OCD treatments. We examined two third-wave, mindfulness-based therapies (1) acceptance and commitment therapy (ACT) and (2) mindfulness-based cognitive therapy (MBCT) as treatments for OCD. We expected ACT/MBCT to have (1a) significantly higher OCD symptom reduction rates, (1b) higher treatment response rates, and (1c) lower dropout rates than a control (progressive relaxation training/PRT), as well as (2a) equal/higher OCD symptom reduction rates, (2b) …

Understanding Work And Sleep Through A Machine Learning Approach, Jennifer Saucedo, Josh J. Prasad, Tori L. Crain

Student Research Symposium

The present study will utilize machine learning methods to find the individual factors (e.g, demographic, lifestyle, contextual, work-related) best predict sleep. I will examine (1) whether machine learning techniques better predict sleep over linear prediction methods and (2) what factors are most important when predicting sleep. Using government-funded data from the Bureau of Labor Statistics (BLS), a variety of prediction methods will be utilized to evaluate and compare predictive performance across 2018, 2019, and 2020. Results found will have a variety of theoretical and practical implications for scientists and practitioners.

Hemp-Lime Insulation: A Climate Friendly Building Material, Ginger Rose Jensen

Student Research Symposium

It is critical to reduce greenhouse gas from the atmosphere to reduce the impacts of climate change. Oregon’s Climate Action Plan has established goals to reduce emissions by developing ‘Clean Buildings’ and increasing the CO₂ sequestered by the state's ‘Natural and Working Lands’. Carbon negative construction materials like hemp-lime insulation could contribute to both goals.

Hemp-lime is a non-structural insulation material made from crushed hemp hurd, a lime-based binder, and water. It is non-toxic and versatile alternative to traditional insulation materials. Hemp-lime was submitted to be added to the International Residential Codes (IRC) index in 2022. IRC approval would …

Case Study In Activist Applied Linguistics: Working With The Oregon Judicial Department For The Accessibility Of Domestic Relations Information, Amandalyn R. Wayland, Jamal R. Ford, Abbee A. Mortensen

Student Research Symposium

How are students of applied linguistics able to contribute to community efforts in increasing access to justice? Activist applied linguistics (AAL) (Cowal & Leung, 2021) is defined as utilizing applied linguistics in coordination with community partners to address wicked problems (Rittel & Webber, 1973). AAL provides a framework for engaging university students with communities outside of their campus and has been utilized to further work in water justice (Haeffner & Cowal, 2019) and to increase the Oregon State Bar website’s comprehensibility (Anesa, Cowal, & Pulju, 2022). In this poster, we present an AAL case study in which students of applied …

Mental Health In Student Leadership: Perceptions Of Ability, Rose M. Jardine

Student Research Symposium

This proposal aims to evaluate the relationship between perceptions of mental health and leadership ability among student leaders in university communities.

Over fifty participants, including faculty and students, from Oregon universities and community colleges are expected to contribute to this study. Participants will answer a survey and be randomly assigned to one of four situations describing a student leader’s disclosure or non-disclosure, both with and without Bipolar 1 Disorder. Bipolar 1 Disorder was chosen for this study based on its intermittence, varying severity, higher associated stigma, and symptomatology that can include externally perceived increased productivity. They will respond to this …

The Effects Of Approach And Avoidance Dispositions And Sense Of Power On Promotive And Prohibitive Voice Efficacy, Christopher J. Waterbury, Avery N. Waklatsi, Amy Pytlovany Ph.D.

Student Research Symposium

Developments in research on promotive and prohibitive voice in workplaces have important implications for organizational innovation and prevention of unethical behavior. Drawing on theory that approach and avoidance dispositions predict promotive and prohibitive voice, and mediate the effect of a sense of powerfulness or powerlessness to predict voice or silence, the proposed study hypothesizes that approach and avoidance disposition will explain differential effects of personal sense of power on an employee’s perceived efficacy of promotive and prohibitive voice. 200 front-line restaurant workers will be recruited and randomly assigned to receive a (1) powerful prime, (2) powerless prime, or (3) control …

Reduce, Reuse And Deny: How Sustainability Is Judged By Consumers, Madison E. Hill

Student Research Symposium

This research was an analysis of a series of interviews regarding what factors are considered when deciding if a given product is environmentally friendly or not. Participants were asked to select between products or practices as the generally more sustainable option, and were asked to explain their reasoning for that decision. Participants were encouraged to describe their reasoning behind each choice, but it was noted when certain choices were more challenging than others. Products that green-wash effectively generate trust between consumers trying to ‘do their part’ and industries attempting to capitalize on each side of environmental crises. Most sustainable practices …

Daily Work, Nonwork, And Stress Experiences Of Students, Erika A. Schemmel, Tori L. Crain, Rachel G. Lucas-Thompson

Student Research Symposium

A substantial body of literature exists that examines work, nonwork, and stress in employed adults. Less is known about experiences of stress in adolescents and emerging adults. The goal of the present study is to examine the association between daily activities and next day stress within a sample of students. We propose that students use their personal resources to meet school demands, and then need to replenish those resources, or stress may ensure. One aim of this study is to examine the relationship of hours of exercise and sleep with students’ reports of stress the next day. Additionally, many students …

Climate Model Skill At Simulating Large-Scale Atmospheric Circulation Patterns And Associated Temperature And Precipitation Over The Pacific Northwest, Graham Taylor

Student Research Symposium

The ability of the latest state-of-the-art suite of climate models to simulate observed large-scale atmospheric circulation patterns over the Pacific Northwest of North America is evaluated. Twelve representative patterns of atmospheric circulation are identified using machine learning applied to observational data. Climate model data from simulations of the historical period are mapped to each observational-derived pattern, and the resulting differences between patterns, as well as differences in frequency of pattern occurrence, are quantified. In general, models are able to simulate the range of circulation patterns with reasonable accuracy, although model skill varies to some degree across the 25-member climate model …

Evaluation Of Oregon’S Food Waste Recovery And Reintegration Policy Adoption Through Civic Capacity, Jenna N. Stathopoulos

Student Research Symposium

The US Food System is complex and multi-layered, containing many areas for improvement. My research focuses specifically on the issue area of food waste. On a global and national scale mitigating food waste can seem too large to manage. Containing complexity across multiple sectors and with extended timelines for improvements, it is indeed a wicked problem, a problem which in its complexity is almost impossible to fully distinguish or address with one (or even multiple) solutions. (Rittel, 1973). However, when we look to local, place-based solutions we can develop more realistic and actionable plans. The state of Oregon is equipped …

Examination Of An Individual-Level Stigma Reduction Tactic In Front-Line Service Encounters, Christopher J. Waterbury, Nicholas A. Smith Phd., Larry Martinez Phd., Shi (Tracy) Xu Phd.

OHSU-PSU School of Public Health Annual Conference

Minority stress theory links short- and long-term negative health outcomes to stigma and discrimination. It is important that workers have the agency to effect change in the processes of discrimination as a social determinate of health. Identity management strategies are elective tactics that workers may wish to use to reduce discrimination. Front line service workers may be discriminated against by customers in the form of negative customer service evaluations. Group-level stereotypes may influence customer service perceptions more than objective service quality. In this poster, we report findings from two studies in which we examined the effectiveness of an individual-level stigma …

Effect Of Sin Lek Rice Intervention On Cognitive Function, Dietary Patterns, And Fecal Microbiota Of Elementary School Children In Chiang Rai, Thailand, Angie Setthavongsack, Siam Popluechai, Jackilen Shannon, Justin Denny, Eleni Gentekaki, Kongkiat Kespechara, Lucsame Gruneck, Thomas J. Sharpton, Kullawong Niwed, Lisa K. Marriott

OHSU-PSU School of Public Health Annual Conference

Thailand has struggled with malnutrition rates in young children. Rice is a key component of Southeast Asian diets and a whole grain rice varietal (Sin Lek) may support improved nutrition. Diet can influence cognitive function and human gut microbiota, which were explored in the context of a rice intervention. We conducted a pilot study using a non-randomized, crossover clinical trial of Sin Lek rice versus traditional white rice consumption in elementary school children in Chiang Rai, Thailand. Outcomes related to diet, anthropological factors, cognitive function (e.g., short-term working memory, attention, impulsivity), and gut microbial populations were measured at baseline and …

Motivational Factors And Opportunities To Science, Technology, Engineering, And Mathematics (Stem) Majors Among Native Hawaiian And Other Pacific Islanders (Nhpi), Shanthia Espinosa, Alma M. O. Trinidad

McNair Symposium

Higher education is a contentious space that poses challenges and barriers to the science, technology, engineering, and math (STEM) fields. This study explores the motivational factors and opportunities to STEM fields among Native Hawaiian Pacific Islanders (NHPI). A qualitative method was used in this study, examining public archival data (e.g., videos, recordings, digital information, etc.) of self-identified NHPI scientists, scholar-activists, leaders, and their narratives of entering the STEM fields. Specifically, the portrayal of needs and promotion of NHPI representation and access were examined, including messages that inspire and encourage STEM interest among NHPI youth. This study explores motivation, opportunities, and …

A Cyber-Anthropological Interrogation Of East Asian Parenting Styles And Kinship Systems, Catherine Lefevre, Charles H. Klein

McNair Symposium

Cyber-anthropology is a crucial, and perhaps underexplored, aspect of contemporary anthropological research. Cyber-anthropologists seek to analyze and comprehend the seemingly complex reciprocal relations that exist between humans and computer driven realities. Cyber-anthropology is certainly applicable to ethnographic research and analysis. Dr. Amy Chua dissects the East-Asian cultural phenomenon of the “Tiger Mom” and the relatively strict parenting style often associated with Tiger Mothers and East-Asian cultural communities. This research paper examines East-Asian parenting styles, specifically the concept of the “Tiger Mom” and the correlatives that exist regarding academic performance, mental health and the disparities that often present themselves when examined …

Exploring How Gentrification-Related Effects Impact The Health Of Older Black Adults, Ann Wachana, Holly Hinson

McNair Symposium

Black adults living in gentrifying neighborhoods experience cultural incongruence with new, often younger, high SES and White residents. In addition, older Black adults are losing deep ties to their neighborhood. This is a major loss to their social network and their sense of belonging within their own neighborhoods. Disruption of long-standing social ties can cause changes in mental health and raises concerns about gentrification’s potentially disruptive impact on cognitive health and the brain aging process. In order to learn more about the experience of older Black adults within a rapidly changing city, focus group discussions from the Sharing History through …

Perceptual Mismatch Between Meso And Macro Policy At Tokyo International University, Brianna Ross, Kimberly Brown

McNair Symposium

Previous studies have aimed at looking at meso and micro policy levels of Japanese educational institutions and their English language teaching programs. Through conducting surveys and interviews, researchers gained knowledge of how, or if, institutions portray their standards to students and staff and how those goals are displayed through curriculum. This research shows a disconnect between the stated goals and in class instruction. While the researchers looked at overall disconnects, none looked at specific universities and their programs. My study aims to fill that gap, focusing on a university known for its English teaching and production skills. The intention is …

Comparing Heavy Metal Content Found In Spinach (Spinacia Oleracea) Grown On The Roof And Ground Sites At Portland State University, Tyler Robin, Gwynn R. Johnson, Olyssa Starry

McNair Symposium

As a result of urbanization, fresh, healthy food can be expensive and easily contaminated but space for local farming is limited. Roofs can be underutilized in densely populated cities and can offer a space for local fresh farming. The purpose of this study is to find if growing leafy vegetables on the roof can limit heavy metal exposure from air pollutants. By growing Spinach on five roofs and five ground locations around the Portland State University campus, at varying heights, we can extract the heavy metals found in these greens and compare them to each other. The expected results show …

Liberalism, Settlement, Sacrifice: Towards A Genealogy Of Sacrificial Politics, Marshall Scheider, Adam Culver

McNair Symposium

In recent years, political theorists have begun to explore the sacrificial dimensions of liberalism and neoliberalism in the global North. Little of this work, however, grapples with the ways settler colonialism informs contemporary political sacrifice or conceptions of the sacrificial. This paper traces a genealogy of contemporary political sacrifice through the archive of early British colonialism in North America. When theorists ignore this archive, they do more than render colonization mute: they also fail to apprehend what I term political sacrifice’s differential function—the mechanism by which sacrifice’s burdens fall on subordinated groups while its benefits accrue to the socially, politically, …

Feedback Timing: Relationship To Student Success In Online Education, Emaleia J. Anton, Nicholas A. Smith

Student Research Symposium

It’s important that researchers identify factors that support student success in online education because utilization of remote learning has increased over the years. Feedback timing is a vital factor contributing to student success in online educational environments. The purpose of this research is to experimentally examine effects of feedback timing on online student success, which this study operationalizes as student perception of self-efficacy. Conducting a between-subjects experimental design, 100 undergraduate students will participate in an online synchronous crash course and will be randomly assigned to different conditions of the independent variable where they will receive either prompt or delayed feedback …

The Impact Of Professors’ Heterosexual Identity In Higher Education Classrooms, Sam Barr

Student Research Symposium

This proposed study is concerned with lesbian, gay, and bisexual (LGB) student’s perceptions of classroom climate, and the potential negative impacts of these perceptions. A poor classroom climate can decrease student participation and contribute to minority stress, which can be a barrier to successful higher education. In this study, we plan to inspect the impact of professors’ heterosexual identities on their scores of Classroom Diversity Climate (CDC). We hope to recruit heterosexual Portland State University professors and their students for our study. After randomly assigning professors to either an intervention on integrative heterosexuality or to a waitlist (control) group, we …
