10:30-11:30: From Central America to the Pacific Northwest: Migration and Displacement

James Daria, Anthropology

Ricardo Valencia, Media Studies

Ricardo Velázquez, History

►Show Full Abstract

The common discourse surrounding migration is routinely framed as individual choice. This panel seeks to analyze discourses of and motivations for migration and posits that individual agency is less important than structural forces such as poverty, violence, and media representations.  Ricardo Valencia, doctoral student in Media Studies, analyzes media responses in the US to the influx of migrant children from Central America. James Daria, PhD candidate in cultural anthropology, uncovers the hidden exile of forcibly displaced indigenous migrants from southern to northern Mexico and the US due to political violence. Ricardo Velázquez, MA student in History, challenges the agential model of migration through oral histories of migrants from Guanajuato to the United States. All three panelists offer an invitation to explore hidden aspects of migratory patterns and how discourses are framed around such issues.

11:45-12:45: Processual South Asia: Cracking Open the Black Boxes of Law, Democracy, Infrastructure, and Governance

Sarah Hamid, Media Studies

Patrick Jones, Media Studies

Lindsay Massara, Law

Tariq Rahman, International Studies

►Show Full Abstract

Since the establishment of trade routes by early Romans, South Asia has captured the attention of European thinkers. For centuries, pearls, diamonds, spices, and luxuries made their way to European consumers through tight networks of trade; in exchange, Enlightenment thought, scientific rationalism, and, eventually, colonial rule made their way to the subcontinent. Accordingly, Orientalists took up the project of translating South Asia to the Western academy, naturalizing Eurocentric representations that calcified into bounded theorizations of the region, one “made eternally ancient” by essentialization (Inden, 1990). In this panel, we interrogate these traditional sociological orderings by deploying recent innovations in sociological thought to make sense of the empirical realities of South Asia. In place of static representations of law, democracy, infrastructure, and governance, we offer processual constitutions attentive to genealogy, power, and associations.Theorizing a “hybrid” legal system in Jammu and Kashmir, Lindsay Massara illuminates the ways that the Constitutions of India and Jammu and Kashmir are interwoven and activated through an unspoken regime of control, resistance, and precedence. Patrick Jones breaks open the black box of Electronic Voting Machines in India, suspending normative assertions about the technology’s value or function and accounting for the ways that EVMs play an active role in structuring democracy. In rural Pakistan, Tariq Rahman explores how local entrepreneurs use physical and digital translocal networks to provide infrastructural services that the state is expected, but fails, to deliver, thus redrawing the lines of the state in its margins. Finally, Sarah Hamid considers big data-governance in India, demonstrating how it takes on the appearance of transparency while obfuscating the politics of privacy, data rights, and legal ambiguities. In analyzing South Asia through a contemporary sociological framework, we revive ancient trade routes but produce new conceptual syntheses that overcome the epistemological violence of traditional Western sociological orderings.

1:00-2:00: Creative Subversion: Arts and Expectations

Behind the Irony: a Reevaluation of James Gillray’s Fictive Monument ‘Design for Naval Pillar’

Chyna Bounds, Art History

►Show Full Abstract

In eighteenth-century England, general anxieties towards the unchecked and excessive British power and authority were caricaturized in images depicting France and its people. Extensive literature has been published on the representations of French individuals and symbols in satirical prints, yet scholars have neglected to address these issues in prints demonstrating British naval prominence in the guise of fictive monuments. Originally deemed a print glorifying the British Navy’s victory over the French, James Gillray’s (1757-1815) “Design for the Naval Pillar” of 1800 conversely acts as a monument simultaneously criticizing the French and the British under a veiled level of patriotism.

The Trouble with Genre: Luis Alberto Urrea’s The Devil’s Highway A True Story and the (Anti-) Wilderness Adventure Narrative

Ryleigh Nucilli, English

►Show Full Abstract

Critics’ receptions and (mis)representations of nonfiction texts matter, especially when those representations refer to forced crossings of the U.S.-Mexico border as “adventure.” I historicize the evolution of the wilderness adventure in the context of Progressive Era social reform policies and pose the concept of the “(anti-) wilderness adventure” to account for Luis Alberto Urrea’s genre troubling in his reconstruction of a border crossing in The Devil’s Highway. I argue that this troubling confronts readers with the forces that enable some to ascend Everest while others die of hyperthermia in pursuit of purchasing school uniforms for their children.

(Afro)Latinx Theatre: Embodiment and Articulation

Olga Sanchez Saltveit, Theater Arts

►Show Full Abstract

Latinx is an ethnicity of a myriad of cultures formed by syncretism, juxtaposition, fusion, and resistance in countries of the Caribbean, Central and South America, and Mexico. “Afro-Latino” emerged as a term to identify Latinxes who, through their bodies, convey African heritage. In U.S. Latinx theatre productions, people of all races populate the stage, yet there is a dearth of playwriting specifically about the (Afro)Latinx experience. Why is the experience seen but not scripted? I discuss the history and causes of the discrepancy between the embodiment and articulation of the racial diversity of the Latinx community.

Accessing Past Glories: Enhancing Digital Access to UO Intercollegiate Athletics History in the University Archives    

Zachary Bigalke, History

►Show Full Abstract

As its athletic programs have gained national prominence, the University of Oregon has seen increased interest in the school’s athletic history both on campus and from outside researchers. One of the greatest challenges for the University Archives is providing detailed, accurate information about the documents and material resources in its athletics collections. In a digital age, aids for finding online publications are of utmost importance because they provide researchers with remote access to evaluate useful resources. My project entails a comprehensive examination of the University Intercollegiate Athletics files to provide greater digital accessibility to UO sports history.

Particle Jet Reconstruction Techniques to Discover New Physics at the Large Hadron Collider    

Johan Bonilla, Physics

►Show Full Abstract

The ATLAS Experiment is one of several large collaborations at the European Organization for Nuclear Research (CERN) aiming to unravel the fundamental properties of particles making up our universe. The Large Hadron Collider currently collides protons with enough energy to produce all Standard Model particles and probe the “tera-scale” in hopes of finding new physics. Each collision within the detector leaves energy deposits in the calorimeters, which are then reconstructed into photons, quark-showers, and leptons. Event reconstruction is an on-going research effort driving analysis teams around the world. At the University of Oregon, we are developing advanced techniques to improve jet reconstruction and facilitate our search for supersymmetric particles.

Identifying Male Victims of Partner Abuse: A Review and Critique of Screening Instruments      

Anjuli Chitkara, Counseling Psychology

►Show Full Abstract

Accurate identification of partner abuse (PA) victims and perpetrators is essential for prevention. Important progress has been made with regard to identification of female victims of PA, but significantly less attention has been given to screening instruments that capture men’s PA experiences. I provide a brief history of PA screening and an organized critique of current screening tools. A gender-inclusive approach is used to critique eight PA screening tools along the following themes: theoretical/paradigmatic approach, language, abuse type, severity and frequency, format, and psychometric data. Strengths, critiques, and future recommendations are offered to researchers and clinicians.

Stories in the Mud: Long-term Water Quality Drivers in the Oregon Coast Range, USA

Geoffrey Johnson, Geography

►Show Full Abstract

Extending our knowledge of environmental conditions beyond the historical record offers the prospect of understanding landscape change with a long-term perspective. Using local knowledge, historical references, and empirical data, we can reconstruct past events and processes recorded in natural archives. Sediment accumulating in water bodies is one such archive. From April 2014 to August 2015, I collected sediment cores from the Coos Bay Estuary to extend the record of water quality drivers beyond Euro-American settlement. With explicit treatment of human influence, I examine the synergistic effects of climate and human influence in this temperate zone watershed.

11:45-12:45: Stress and Coping

Executive Functions Predict Active Coping Behaviors in Disadvantaged Youth     

Kelsey Kuperman, Counseling Psychology

►Show Full Abstract

Understanding sources of individual variation in active coping behaviors during adolescence is important for promoting better health outcomes, especially among disadvantaged youth. Using longitudinal data from 387 adolescents (13.5 ± 0.9 years; 52% female), we examined whether working memory (WM) predicts adolescents’ use of three distinct forms of active coping behaviors. Stronger WM (and lower impulsivity) at baseline predicts greater use of all three coping behaviors over time. Adolescents of low socioeconomic status (SES) reported lower rates of active coping, primarily because of the detrimental effects of SES on WM. Findings emphasize the importance of prefrontally mediated self-regulation in the development of active coping behaviors.

Captive Bonobo Urinary Cortisol Follows Diurnal Rhythm: Implications For Primate Socio-Endocrinology Research

Erica Midttveit, Human Physiology

►Show Full Abstract

In humans, cortisol production follows a diurnal rhythm. Few studies have taken diurnal rhythm into consideration in bonobos. We hypothesized that bonobo cortisol follows a similar diurnal rhythm.  Urinary cortisol samples from a captive population of bonobos (n = 13) were analyzed for cortisol concentration. Four samples per individual (2 am, 2 pm) were analyzed to calculate mean morning and evening values. Most bonobos followed the expected diurnal pattern. The two individuals that did not are among the lowest ranking in the group. Including diurnal rhythm considerations has important implications for understanding nonhuman primate stress in an evolutionary context.

Does the Body Keep Score? Awareness of Internal Body Sensations Among Sexual Trauma Survivors 

Kristen Reinhardt, Psychology

►Show Full Abstract

Sexual trauma is costly to survivors and society through increased healthcare utilization and negative physical and mental health outcomes. Yoga is effective for reducing symptoms following sexual trauma, although limited information exists about constructs mediating symptom reduction following yoga practice. Interoceptive awareness (IA; internal body sensation awareness) is a proposed mediator, although no empirical evidence has tested this claim, and scant information is available on whether IA changes following sexual trauma experience. In our preliminary study (n = 103), we found negative relationships between sexual trauma and IA.

Variable Practice and the Learning of New Gait Patterns   

Jacob Hinkel-Lipsker, Human Physiology

►Show Full Abstract

Gait rehabilitation methods that restore walking symmetry in individuals with unilateral deficiencies (such as amputees and individuals recovering from stroke) improve quality of life by increasing gait efficiency. Researchers do not know, however, how to best restore this symmetry. As a proof of concept, we recruited healthy individuals to walk on a split-belt treadmill, with the belts moving at different speeds, to induce an amputee-like gait asymmetry. Preliminary results indicate that when we implement a more challenging practice schedule, where the belt speeds are unpredictable, the ability to control balance increases following a training period.

Failing to Plan But Not Planning to Fail: A Theory of Entrepreneur Optimism and Business Planning      

Jeffrey Gish, Management

►Show Full Abstract

Entrepreneurs tend to be optimistically biased about their chances for success. Does their optimism persist when confronted with more realistic cues? Business planning gives entrepreneurs an opportunity to seek out these cues, but extant literature is unclear about how business planning affects entrepreneur optimism. Some recent studies indicate that optimism bias can actually increase when entrepreneurs plan, as a result of perceived insider knowledge. Other results suggest that entrepreneurs may heed the grounding cues that planning provides. I posit that the effect of new venture business planning on optimism bias will vary, increasing in specific contexts and decreasing in others.

A Crossmodal Roelofs Effect: Evidence for a Shared Frame of Reference for Auditory and Visual Perception

Jeff Peterson, Psychology

►Show Full Abstract

Although auditory and visual information are detected through different mechanisms, our perceptual experience is generally unified. We adapted a visual illusion (the Roelofs effect) that distorts an observer’s perception of straight ahead and measured the perceived location of auditory stimuli. Contextual visual cues induced a systematic bias of auditory targets, but contextual auditory cues were insufficient to bias localization of visual targets in an analogous fashion. These results suggest that the location of auditory and visual stimuli are encoded within the same frame of reference, the establishment of which is influenced by contextual visual but not auditory cues.

Early Glulam: A History of Glued-Laminated Timber Manufactured Prior to 1963, Its Deterioration, and Its Preservation

Rachelle Byarlay, Historic Preservation

►Show Full Abstract

Glue-laminated timber (glulam) is a structural building material that differs from sawn timber because it is manufactured by gluing smaller lumber together to create one larger structural member. Glulam arrived in the United States in 1934 but was not widely used until after World War II. The United States did not establish a manufacturing standard until 1963. Extant glulam buildings and structures built prior to 1963 are now over 50 years old and eligible for the National Register of Historic Places. To help preserve these historic resources, this study documents the history, deterioration patterns, and conservation methods of early glulam.

Engaging Suppliers in Social & Environmental Responsibility Using Auditing        

Hossein Rikhtehgar Berenji, Operations & Business Analytics

►Show Full Abstract

Recently, customers in the market have been paying more attention to the social and environmental responsibilities of the supply chain. Market leaders have experienced brand damage and loss of revenue as a result of the social and environmental responsibility violations of their suppliers. Market leaders use auditing as a tool to engage their suppliers in social and environmental responsibility. We model the auditing process in the presence of market demand and corrective actions when the supplier fails the audit. We explored these questions: Under what circumstances does auditing improve the supplier responsibility effort? How do contract terms interact with the supplier responsibility effort? We find interesting buyer’s best response functions that are different from normal behavior and in some cases deviate from conventional wisdom.

Fluid Boundaries: Envisioning Catastrophic Risk on the Oregon Coast       

Dan Shtob, Environmental Studies

►Show Full Abstract

In recent years, social science researchers have begun to employ sociological theory to understand our idiosyncratic responses to environmental change. At present, the Oregon coast is facing the dual perils of climate change and the potentially catastrophic Cascadia subduction zone earthquake and tsunami and remains relatively unprepared for these events. Using 25 ethnographic interviews with residents of Coos Bay, Oregon, I am tracing the methods by which people facing these events socially construct their visions of future change by “remembering the future,” how community and place identities inform this construction, and how constructed future memories may motivate action or apathy.

Ethics in the Digital Age: A Comparison of the Effects of Online Context on Moral Judgment

Matthew Pittman, Media Studies

►Show Full Abstract

Media still have the power to set the public’s agenda and to shape ethical decision making. More and more Americans—millennials in particular—are getting their news online from social media feeds. However, unlike the sites of news organizations themselves (e.g., NYtimes.com), where stories are grouped by content, social media feeds often display news headlines between random or frivolous content. This study involved a controlled experiment to see whether contextual dissonance can impair moral judgment of online news stories. The hypothesis is that participants reading a news story in a contextually congruous environment (news website) have higher levels of moral reasoning than do participants who read the same story in a contextually dissonant environment.

Follow the Money: Effectiveness of Climate Goals in Shaping Transportation Spending  

Rory Isbell, Nonprofit Community and Regional Planning

►Show Full Abstract

This research assesses linkages between climate goals set by federal, state, and regional governments and the actual transportation funding decisions made at state, regional, and local levels. Many jurisdictions have established climate goals and performance measures in their transportation planning that seek to reduce greenhouse gas emissions from the transportation sector. However, actual spending on transportation infrastructure does not always reflect these climate-related policy goals. Through a blend of policy, budgetary, and legal research, this project will evaluate government accountability by comparing goals to prioritize climate in transportation decisions with actual transportation spending.

Pixels as persuasion amid ecological crisis: Videogame activism from the Elaboration Likelihood Model perspective

Derek Moscato, Media Studies

►Show Full Abstract

Society’s most pressing environmental concerns—including climate change, rising ocean levels, air pollution, and threats to wildlife—are increasingly being debated in new media domains such as social networking channels and in the world of video gaming. Through the lens of persuasion theory and the Elaboration Likelihood Model, this study examines the resulting attitudes and perceptions of audiences exposed to such activism-within-a-videogame, specifically evaluating games produced and promoted by People for the Ethical Treatment of Animals (PETA), featuring wildlife protection and animal rights themes. A survey with experimental conditions was used to assess the difference between those exposed to videogame activism versus persuasion delivered on nongaming media platforms.

Examining Longitudinal Associations Between Trauma Exposure and Effortful Control on Marijuana Use in Legalized and Non-legalized States

Aleksandria Perez Grabow, Counseling Psychology

►Show Full Abstract

Legalization of recreational marijuana in the United States continues to be a controversial topic, despite evidence indicating little or no increase in use postlegalization. Most research has focused on postlegalization changes in use, without consideration of factors that might interact to influence use.  We measured associations between trauma, effortful control, and marijuana use in a sample of 319 young women prior to the legalization of recreational marijuana in three states and compared results to those from states that had not legalized recreational marijuana use. Trauma and effortful control were linked to marijuana use and earlier onset, and these associations did not differ between states that had legalized and those that had not legalized recreational marijuana use.

Archiving and Sharing Native Language Materials Responsibilities and Ramifications     

Jaeci Hall, Linguistics

►Show Full Abstract

The Northwest Indian Language Institute (NILI) helps language communities revitalize their native languages by caretaking previous language materials, creating new language materials, and providing community access to these materials. As an NILI Graduate Research Fellow, I research how to create a language material conduit between communities and academia through the lens of cultural and academic viewpoints. My goal is to serve the needs of tribal and academic communities, protect the linguistic material, and maintain academic integrity. These language materials are fundamental to language revitalization.

Diabetes in Mexico: Cultural Beliefs and Management in an Urban Setting          

Kate Stoysich, International Studies

►Show Full Abstract

The incidence of type 2 diabetes has increased across the world, including places such as Mexico with a rate of 11.9%. Research shows this increase is related to shifts in lifestyles among urban populations. This study uses clinical and community observations and semi-structured interviews conducted in Mazatlán, Mexico to understand how patients’ explanatory models of illness compare with providers’ perspectives. Findings reveal gaps between illness causation models and management strategies. This study examines how changes associated with globalization create a riskscape for diabetes. I conclude with implications for culturally appropriate care for health clinics in Mexico and patients of Mexican heritage in United States.

Heavy Resistance: Modes of Resilience in Fat Acceptance Activism         

Alexis Yalon, Anthropology

►Show Full Abstract

Fat acceptance activists in the Pacific Northwest are organizing to support one another and fight weight-based oppression. This research examines their strategies for resisting dominant cultural narratives about the worth of fat bodies and lives. Online activism and community building are important elements of fat activism yet are often conceptualized as separate from the “real” or offline world. This presentation examines online interactions as embodied practices to challenge the binary distinction between Internet-based and “real world” activism.

10:30-11:30: Social Determinants of Neurobiology and Stress

Ryan Giuliano, Psychology

Erik Knight, Psychology

Melissa Liebert, Anthropology

Brianna Mintz, Couples & Family Therapy

Leslie Roos, Psychology

►Show Full Abstract

Evidence is emerging across disciplines of research demonstrating that many basic health functions and outcomes are influenced by an individual’s social environment.  In particular, socioeconomic adversity and psychosocial stress have been shown to have toxic effects on a wide range of behavioral and biological regulatory functions, with consequences for physical and mental health outcomes across the lifespan. This group panel will present findings demonstrating how measures of the brain, autonomic nervous system, inflammation, hormones, and behavior are affected by adversity as a result of both chronic and acute environmental stress.In contrast to much psychological research that relies solely on undergraduate volunteers, the research presented here involves a focused effort to include individuals from more diverse cultural and economic backgrounds. Notably, Melissa Liebert will present data demonstrating how stress hormones of individuals from an indigenous Amazonian population are impacted by the introduction of global market influences.

A major innovative focus of this work is the integration of multiple biological markers of stress physiology. In particular, several presenters will be providing evidence that activity of the autonomic nervous system is a critical moderator of the impact of stress on brain, behavior, and inflammatory functions. Additionally, research will be presented describing innovative experimental methods for studying the causal effects of social variables like subjective social status on the stress response.

Much of this work has been performed in the local Eugene community in the context of interventions designed to improve child development and parent-child interactions. A critical component of the execution of this work has been the development of close relationships with agencies providing services to underserved and underrepresented families, such as Head Start of Lane County. These presentations will discuss key implications for policy, translational science, and future intervention work that seeks to ameliorate the negative effects of stress exposure.

11:45-12:45: Start Making Sense: How Symbiosis Between Social Sciences and Student Life Can Prove and Improve Student Experiences 

Philippe Bou Malham, Psychology

Brian Clark, Psychology

Hillel Samlan, Counseling Psychology

Yue Shen, Educational Leadership

►Show Full Abstract

Assessment of learning, programs, and services plays an ever increasing role in higher education. At the University of Oregon, the Division of Student Life has sought to apply these principles and methods, which had previously been used primarily within academic departments. In order to accomplish its goals of better understanding and quantifying its efficacy and value, Student Life assessment needs applied social scientists. Social science programs can also benefit from a relationship with Student Life, particularly connecting at the graduate student level. In an overcrowded market, many students are looking outside of the traditional academic tenure track, which most of them once had dreams of pursuing. If assessment in Student Life continues to grow, it will provide social scientists an “alternative-academic” track. And if Student Life assessment is to be successful, it will need people with rigorous training in research on humans and sophisticated data-analytic skills.In practice, the purpose and mission of various services inevitably frame the paradigm of assessment. As first-hand consumers of this type of applied research, the necessity and perspective of a range of student service professionals drive the development and diversification of methodologies in assessment, while imposing limitations on the methodological rigor and depth of inquiry.

In this panel, four doctoral students from across the social sciences working for different units in assessment roles in Student Life make a case of this symbiotic relationship, showcase what their unique social science training and perspective adds to Student Life assessment, and explore the implications of their work for policy and accountability systems.

Greening the Gulag: Politics of Sustainability in Prison      

Jewell Bohlinger, Geography

►Show Full Abstract

The prison population is reaching critical mass, and the United States now incarcerates over 25% of the world’s prisoners. Recently, prisons have been criticized for their environmental impacts, such as high energy consumption, over-crowding, and pollution. In response to these facts and calls to action by the U.S. Justice Department to implement more sustainable and cost-effective strategies in prisons, a surge in prison sustainability programs is occurring throughout the country. Although sustainability is an important challenge facing the world, some researchers have argued that these changes are being made with environmental sustainability and the sustainability of current levels of incarceration in mind.

Comparing Environmental Performance and Indoor Comfort of LEED certified and Conventional schools in Houston, Texas, USA.       

Tanvi Dhar, Architecture

►Show Full Abstract

In the United States, 55.3 million students in K-12 schools spend at least 40 hours per week in classrooms. The U.S. Environmental Protection Agency reported that 40% of the nation’s schools have poor environmental conditions that inhibit learning and pose increased health risks. To address these issues, in 2007, the U.S. Green Building Council created a third-party-certification benchmark: LEED (Leadership in Energy and Environmental Design) for high-performance schools. However, few studies have been conducted to investigate the claimed improved performance of LEED schools. In order to establish a relationship between LEED certification credits and buildings environmental impact, I will compare and assess the performance of LEED schools with that of conventional schools using postoccupancy evaluation.

Intergenerational Impact of Adverse Childhood Experiences: Assessing Continuity Between Teenage Girls and Primary Caregivers    

Cady Kintner, Counseling Psychology

►Show Full Abstract

Research has shown that cumulative exposure to different categories of adverse childhood experiences increases the risk of poor health-related outcomes later in life. Less is known about how trauma experienced as a child may affect parents’ likelihood of exposing their children to similar adverse experiences. A better understanding of the intergenerational impact of childhood trauma is crucial to preventive interventions aimed at helping family systems at risk. The present study is being conducted to assess an at-risk sample of teenage girls and their primary caregivers and explore parent-child relational quality as a potential moderator of intergenerational transmission of trauma. Implications for policy and practice will be discussed.

Be Sure to Like Us on Facebook: Social Capital and Opinion Leadership in Online Word-of-Mouth          

Alec Tefertiller, Media Studies

►Show Full Abstract

Communication research has long recognized the value of opinion leaders in transmitting news and product recommendations to the public; however, the promise of the social capital created through online social networks such as Facebook and Twitter is that everyone could become a recommendation source. This study was conducted to determine whether social capital or a traditional understanding of opinion leadership better predicted the online recommendation of cultural goods, in this case books. The key finding was that bridging social capital was most influential in low-involvement sharing, and perceived opinion leadership best predicted high-involvement sharing.

Calculations in the Homotopy Groups of Spheres

Leanne Merrill, Mathematics

►Show Full Abstract

In algebraic topology, we use algebra to study high-dimensional shapes (i.e., five or more dimensions). Humans perceive three dimensions easily, so we can visually distinguish between a figure-eight and a circle. But we cannot use the same visual analysis to compare shapes in, for example, nine dimensions! I use powerful algebraic tools such as spectral sequences and homotopy groups to study high-dimensional shapes. Specifically, I calculate the homotopy groups of high-dimensional spheres. The techniques I am developing are used in pure mathematics but also have applications to data analysis, where each characteristic of a data point is a new “dimension.”

Tiny-House Communities as a Response to Homelessness: Spatial Patterns that Support Community Cohesion

Lyndsey Deaton, Architecture

►Show Full Abstract

Occupants of informal communities have developed spatial and design preferences resulting from their experience in communal living at the periphery of society. These preferences have been conveyed through rich narratives and most recently through qualitative methods (informant interviews and site observations). However, the architecture profession is lacking quantitative analysis of occupant preferences across multiple sites. This research project will survey qualifying potential occupants for three micro-home communities (Austin, TX; Eugene, OR; Portland, OR) and determine trends in the spatial and design preferences. Architects and urban planners will use the research to inform design decisions during residential development to produce housing that more closely meets tenants housing needs.

Cinderella’s Glass Ceiling:  Boxing, the Great Depression, and Irish-American Identity

Chelsea Oden, Music Theory

►Show Full Abstract

Like other minorities immigrating to the United States in the 1800s and early 1900s, the Irish were met with a climate of discrimination. Consequently, these minorities filled boxing rings. In Madison Square Garden, along the trajectory between the Great Depression and the Second World War, first-generation Irish American James J. Braddock claimed for Irish Americans an American identity. His underdog victory over Max Baer for the 1935 heavyweight boxing title earned him the nickname Cinderella Man, and the glass ceiling hanging over Irish Americans began to shatter.

Reducing the Musical Workspace: Favorite Songs in Early Infancy

Jennifer Mendoza, Psychology

►Show Full Abstract

Singing with young infants is a ubiquitous human activity. How do parents select what songs to sing? How do infants learn coherent structures across the experienced words, rhythms, and melodies? We present evidence that the early musical ecology may be well-suited to the statistical sampling and learning challenges of infants and their parents. Parents (n = 97, infants 6-18 months) completed a questionnaire about their everyday musical experience. Their answers to the question “Does your infant have any favorite songs?” revealed a limited range of readily available songs. Most parents (.59) easily remembered and reported specific songs. From the estimated 97 million songs in the universe, only 73 unique songs were reported by parents. The same three songs (“Itsy Bitsy Spider,” “Twinkle Little Star,” and “ABCs”) accounted for a quarter of the distribution, and nearly half of parents (.49) reported that their infant’s favorite song was one of these three. These findings match distributional properties of songs that parents sing to their infants in a laboratory setting, strongly suggesting a constrained early ecology. A reduced musical workspace may support memory retrieval in the singer and learning in the listener.

Relationships Between Parent Mental Health and Parent and Teacher Perspectives of Oregon Kindergarten Students’ Self-Regulation

Sylvia Shaykis, Counseling Psychology

►Show Full Abstract

Child self-regulation (SR) is associated with many academic and psychosocial outcomes and can be impacted by parents’ mental health. This study explores relationships between parent mental health and parent and teacher perceptions of the self-regulation of 120 kindergarten students from Oregon schools. The research examines associations between parent mental health and parents’ and teachers’ child SR ratings and the effects of parent mental health on the concordance between the two reporters. Implications include confirming hypothesized effects of parent mental health on the accuracy of parent reports and the great importance of parent mental health assessment, support, and intervention.

Infant-tuned Play: Caregivers Enhance Opportunities to Learn about Objects

Jessica Kosie, Psychology

►Show Full Abstract

People tune their behaviors to their social partners, including how they talk to and play with infants. We investigated when, why, and how caregivers modify their behavior in everyday play with infants. We move beyond approaches in which researchers determine the structure of play and instead measure properties of what parents themselves naturally do. As infants learn some objects over the first two years, parents appear to provide new opportunities to learn about other objects. Such tuning at all points along the developmental trajectory may help infants to successfully learn about the many objects in the world.

Collaborative Storytelling: A Digital Approach to Creative Writing in an ESL Classroom

Becky Lawrence, Linguistics

►Show Full Abstract

In a communicative classroom, collaboration is essential; however, in writing courses, collaboration often occurs solely in the revision stage. Collaborative writing can be beneficial for both language improvement and development of cultural awareness. This project outlines an creative writing course for students for whom English is a second language; the course is centered on the collaborative creation of digital narratives. Because second language writing classrooms often focus on research-oriented composition, little attention is given to creative writing. I will discuss the value of creative writing in a second language classroom and the impact of collaboration on language development, cultural awareness, and personal identity.

Informal Art Education Curriculum Accessible for Student with Autism     

Halley Perry, Arts Management

►Show Full Abstract

Art education programs offer formal and informal learning opportunities to individuals with various experiences and abilities. However, there appears to be fewer resources available for museums to contribute to the cognitive, social, and emotional progress of children with autism. It is important for art museums to teach children with autism because these environments provide a social learning opportunity. This study will focus on two programs, one at the Denver Art Museum and the other at the Jordan Schnitzer Museum of Art in Eugene, Oregon. The results from these specific programs will inform development of guidelines for other informal educators creating curriculum accessible to students with autism.

Constructing Spaces of Support: Gender Inclusive Meetups in the Field of High Tech       

Larissa Petrucci, Sociology

►Show Full Abstract

Research on gender, work, and organizations has not often addressed the following question: Do workers take steps to confront institutional norms of exclusion? This research highlights how women and gender-nonconforming (GNC) individuals confront the heteronormative (and predominately white) culture of high-tech by constructing spaces of support where they can be thought leaders, interact with other women and GNC individuals, and develop technical skills in a noncompetitive environment. I found that participants in gender-inclusive tech groups address employment in a male-dominated field by drawing attention to gendered divisions and interactions at work and gendered social expectations that support men’s overrepresentation in tech careers.

Pedagogies of Dispossession and Repossession: The Storied Landscape of Community College  

Nadia Raza, Critical and Socio-Cultural Studies in Education

►Show Full Abstract

Community colleges serve close to half of the undergraduate students in the United States, or approximately 13 million students each year. The majority of students attending community colleges are characterized as nontraditional students—a broad generalization that obscures students’ experiences. My research asks how students who are characterized as “nontraditional” narrate, challenge, and resist discourses of meritocracy and deficit that are normalized as inevitable experiences through the social imaginary and spatial imaginary of neoliberalism. Through a collective interview process at two community colleges in the Pacific Northwest, I will document how nontraditional students narrate their experiences, choices, fears, and triumphs. This project emphasizes possibilities for support and solidarity that emerge from community college education.

Keats Conley, Biology

►Show Full Abstract

I explore intersections between science, art, and education through research on tunicates, a group of marine invertebrates that use mucous nets to filter feed. Although “mucus” often invokes connotations of unstructured slime, these mucous nets are quite ornate. Our research relies on microscopy and videography to characterize the mechanics of mucus feeding, and I use this imagery as a tool to reshape conventional perceptions of mucus. I have created an educational video as an artistic means to make mucous-mesh filter feeding more comprehensible to nonscientists.

There and Back Again: The Feedback Loop Between the Lab and Applied Settings

Devin Howington, Psychology

►Show Full Abstract

While interning at Lane County Family Mediation, I learned about barriers to translation of research to applied settings but also the rewards of connecting research to practice. My psychology research examines how accurately people understanding each other’s thoughts. My task as a mediator is to accurately translate people’s thoughts to find solutions to conflicts. Despite challenges in connecting the two (e.g., confidentiality concerns, government bureaucracy), my experience provided a fruitful feedback loop between the abstract models I had envisioned and how interpersonal accuracy was actually achieved. I recommend that more researchers spend time in applied settings.

Adapting to Climate Change: Land-use and Building Practices in the Marshall Islands      

James Miller, Architecture

►Show Full Abstract

The Republic of the Marshall Islands (RMI) is facing the detrimental effects of sea level rise and will be among the first countries to produce climate refugees. Measures must be taken to mitigate the impacts of sea inundation and tropical storms by revitalizing urban centers through sustainable land use planning and building practices. This study includes an analysis of the evolution of land use and building practices in RMI through archival and participatory research to build consensus toward a shared future for RMI’s urban development and to develop a strategic plan for sustainable land use and building practices.

Teaming with Microbes for Adaptive Food Production

Lucas Nebert, Environmental Sciences, Studies, and Policy

►Show Full Abstract

Seeds are much more than a plant’s progeny. They carry microorganisms from the maternal plant into the following generation in a process known as vertical transmission. Although some of these vertically transmitted microbes are pathogens, the vast majority are not pathogenic. In fact, many seedborne microbes appear to confer benefits to the host plant, such as better nutrient acquisition and protection against pathogens. To further understand the ecology of seedborne microbes, I developed the Community Research Network, a participatory science project in which seed-saving corn growers in the Pacific Northwest can send in seeds for microbial analysis. With the help of this community-sourced research project, we are finding new insights that could lead to promising innovations in agriculture.

Mapping Their Stories: Fan Production and the Network of Genre Remix in Star Trek Fanfiction          

Michelle Alexander, Sociology

►Show Full Abstract

This research was conducted to find a way to understand large bodies of Internet content production on user-generated content sites. Using fanfiction as an example of user-generated content on an archival site, I investigated the production of fanfiction and the self-curating way in which authors use and remix genres. I then used this information to develop an understanding of how the community defines itself. I analyzed the way community members co-create the definition of acceptable forms of fanfiction and self-curate texts. Using social network analytic techniques, I created a visual representation of the genre interconnectedness of Star Trek fanfiction on Fanfiction.net.

Historic Coastal Landscapes: Historic Preservation and Waterfront Redevelopment        

Rodney Bohner, Historic Preservation

►Show Full Abstract

Oregon’s working waterfronts and coastal resources are an important part of the state’s identity and history. Changing roles of waterfront communities is altering the land use along waterfronts — often erasing historic features and heritage tied to the landscape. The objective of this research is to contribute to the understanding of the role of historic preservation along urban waterfronts and help preserve the direct, authentic heritage unique to each waterfront community.

Get Explicit 101: Educating First Year Students on Sexual Violence Prevention and Education    

Eric Braman, Nonprofit Management

►Show Full Abstract

Get Explicit 101 was initiated this year as a way to encourage conversation and learning about healthy sexuality, bystander intervention, and sexual consent. Through the course of the trainings, all students were provided a pre- and postsurvey modeled after the McMahon et al. Modified Bystander Attitude Scale. There will be one additional follow-up survey sent to all participants at the start of winter term. We will be assessing the collected data in order to better understand what growth, understanding, and knowledge was gained through completion of Get Explicit 101. This poster presents an explanation of Get Explicit 101, the steps in program development and execution, and an overview of the result obtained so far.

Laterality of Grooming and Tool Use in Captive Bonobos

Colin Brand, Anthropology

►Show Full Abstract

I compared the laterality of hand use in a simple behavior (grooming) and a complex behavior (tool use) in a group of captive bonobos housed at the Columbus Zoo and Aquarium. Grooming was recorded using scan sampling, and tool use was recorded using all-occurrence sampling. Binomial tests revealed that grooming was ambilateral across all individuals, whereas tool use elicited strong individual hand preference. Six individuals preferred the left hand, and three preferred the right hand. These results are consistent with recent research on a different complex task in captive bonobos that also elicited hand preference but not population-level handedness.

Overcoming the Barriers to Micro-housing  

Emily Brown, Community and Regional Planning

►Show Full Abstract

Micro-villages (tiny-home communities) and individual tiny homes can offer affordable housing opportunities, a sustainable lifestyle, and transitional housing for unhoused people. Although tiny houses are growing in popularity, they are confronted with political, financial, and land use challenges that vary greatly by situation. Tiny-home advocates across the nation are finding creative strategies to overcome these barriers. This poster presents some of these barriers and the strategies that have allowed tiny houses and micro-villages to come to fruition. Research features case studies including micro-villages in Eugene, OR, Olympia, WA, and Portland, OR and tiny-house individuals who live from Oregon to Maryland.

Exploring the Validity of the Use of SMS Text Messaging for Measuring Daily Life Activity of Emerging Adults

Lucia Cardenas, Counseling Psychology

►Show Full Abstract

This study evaluates the validity of the use of a text messaging survey as a unique strategy for measuring the daily activity (alcohol use, substance use, school activity, mood, and parental and peer interaction) in a sample of 227 emerging adults. The survey was administered in four 2-week bursts over 1.5 years. Findings provide a snapshot of daily life in a sample of emerging adults and highlight the importance of evaluating the validity of short message service text messaging as a potential data collection device and assessor of the predictive validity of constructs for prevention and clinical research methods.

Internal Carbon Pricing Proposal at the University of Oregon         

Sonya Carlson, Business Administration

►Show Full Abstract

The University of Oregon conducts a bi-annual greenhouse gas emissions survey. The largest single source of emissions comes from burning natural gas to heat the campus. During the last decade, air travel has increased significantly and is now the second largest source of institutional emissions. In 2014, at the request of a UO faculty member, the Office of Sustainability began researching and developing an internal carbon pricing proposal that links these two largest emissions sources. Some of my work is focused on departmental impacts and possible uses for the money raised.

Differentiation, Engagement, and Motivation: Individual Language Learners in Classroom Communities

Kathryn Carpenter, Linguistics

►Show Full Abstract

Students’ identities need to be reflected in their language-learning experience to facilitate connection to the educational materials. This project will focus on creating a classroom setting where students are able to bring in their own individual identities, feel autonomous and in charge of learning, and therefore be empowered and motivated in the classroom. I will combine traditional differentiation, learner engagement, and motivation, demonstrating ways of motivating students through these tactics. I will also focus on the individual learner and how each class group of individuals using language for their own relevant purposes contributes to a healthy classroom community.

The Innovativeness of Strong Structural Holes        

Stefano Cazzago, Management

►Show Full Abstract

My work investigates the effects of an actor’s social network on his or her individual innovativeness. I focus on the effects of the content (strength) of a person’s dyadic relationships and the structure (density) of his or her aggregated dyadic connections on innovativeness. Empirically strong ties tend to be part of dense networks, and weak ties tend to be bridges; therefore, past research has often failed to differentiate those constructs. Nevertheless, strength and structure are distinctive constructs and can be unrelated. My work advances this field by focusing on both disentangling the distinct effect of strength and structure and on exploring the effect of their interaction on individual innovativeness.

An Autonomic Performance Environment for Exascale

Nicholas Chaimov, Computer and Information Science

►Show Full Abstract

Future supercomputer systems will require new approaches to performance observation, analysis, and runtime decision making to optimize for performance and efficiency. The standard “first-person” model, in which multiple operating system processes and threads observe themselves and record first-person performance profiles or traces for offline analysis, is not adequate to observe and capture interactions at shared resources in highly concurrent, dynamic systems. This model also does not support mechanisms for runtime adaptation. Our approach, called APEX (Autonomic Performance Environment for eXascale), provides mechanisms for sharing information among the layers of the software stack, including hardware, operating and runtime systems, and application code.

Longitudinal Effects of Parental Influences During Middle Adolescence on Sexual Risk Behaviors in Late Adolescence 

Katherine Chrisinger, Counseling Psychology

►Show Full Abstract

Adolescent sexual risk-taking is linked to adverse but largely preventable consequences. Given parents’ central role as socialization agents, understanding specific ways by which parental involvement can reduce sexual risk-taking is critical. Using longitudinal data from 387 adolescents, we examined the effects of parental monitoring and involvement during middle adolescence on sexual initiation, inconsistent condom use, and number of sexual partners during late adolescence. Parental involvement significantly predicted sexual debut and condom use, and monitoring significantly predicted number of partners. By identifying specific ways in which parental involvement can reduce sexual risk-taking, our findings have implications for future research and practice.

From East to West: Accessibility and Bias in Self-Other Comparative Judgments  

Colton Christian, Psychology

►Show Full Abstract

Past research has shown that North American participants demonstrate more self-enhancement in their social comparisons than East Asian participants. However, egocentrism—the tendency for comparisons to be based predominantly on information about the self—has received much less cross-cultural attention. In our work, we examined the relationships between absolute self (“How often do you …?”), absolute other (“How often does the average student …?”), and comparative judgments (“In comparison to the average student, how often do you …?”) in Taiwan and the United States. Across three studies and both cultures, we found that absolute self ratings are weighted more heavily in comparative judgments than are absolute other ratings.

Adipose Tissue p50α/p55α May Drive Acute High Fat Diet Induced Insulin Resistance and Adipose Tissue Inflammation  

Zachary Clayton, Human Physiology

►Show Full Abstract

Phosphoinositide 3-kinase (PI3-K) is a proposed integration point between adipose tissue (AT) immune cell infiltration and insulin action. Previous work suggests that global knockdown of Pik3r1 (the gene encoding regulatory subunits p85α/p55α/p50α of PI3-K) preserves adipocyte and systemic insulin sensitivity, with a parallel decrease in AT macrophage, despite obesity. We found that acute (3d) high-fat diet in wild-type mice significantly decreases systemic glucose tolerance, adipocyte insulin sensitivity, and the anti-inflammatory immune cells in AT. Knockdown of Pik3r1 in AT preserves systemic glucose tolerance and the anti-inflammatory cell phenotype in AT.

Critical Consciousness and Postsecondary Preparation Among Latina/o High School Youth

Darien Combs, Counseling Psychology, Family, and Human Services

►Show Full Abstract

Latina/o high school students’ critical consciousness (CC) of inequity and injustice may be significantly related to their postsecondary education preparation. A multivariate analysis will be used to explore this relationship and whether CC differs as a function of gender, free-and-reduced-lunch status, and parents’ education. Based on the literature, I expect that students higher in CC will be more likely to discuss future plans with school staff, girls will have higher levels of the critical agency component, and students facing more adversity will have lower levels of the critical behavior component.

Sensation Seeking, Impulsivity, and Binge Drinking in Adolescents           

Joshua Crosthwaite, Counseling Psychology, Family, and Human Services

►Show Full Abstract

Adolescent risk-taking behaviors are a substantial burden to society in real dollar and psychosocial costs. Impulsivity (IMP) and sensation seeking (SS) have consistently been implicated in the initiation of risky behaviors during adolescence. The current analysis draws upon data from 387 adolescents (51% female) and pairs levels of SS and IMP to determine correlations with onset of binge drinking. Results indicate that adolescents with high levels of both IMP and SS are more likely to engage in binge drinking behaviors. Results have important implications for future research and practice.

Reading Introduced Species as Accidental Companions in Contemporary Fiction  

Elizabeth Curry, English

►Show Full Abstract

As literary representations of wild animals must now contend with two fundamental problems—the depiction of the animal itself and, more urgently, framing within an ecological context—introduced species that contribute to an accelerating extinction rate complicate an already troubled landscape. My reading of TC Boyle’s When the Killing’s Done proposes that introduced species stand in as both human avatars and kin to endemic animals. Yet, throughout the narrative, “wild” animals remain individually enigmatic and collectively threatened, while introduced species act as murderous pests set loose by misguided human intention or simply by accident. In the novel, notions of animality rest on ecological relationships that seemingly necessitate a language that champions environment over animal. In human-compromised ecosystems (which are now ubiquitous), the moral complexity of human attempts at remediation and further intervention occupies a real place in the ethics of ecology and companionship. Boyle’s novel subscribes to a utilitarian drive that also entertains notions of individual priority. Rationality and irrationality collide early in the novel and remain locked in a contorted embrace throughout as the text takes up quandaries of companion and wild animal representation and responsibility.

Linguistic Ecology: Language Learning in the Wild  

Christopher Daradics, Linguistics

►Show Full Abstract

This project seeks to facilitate language development, cultural participation, and personal growth among outbound American study abroad participants through the creation of a curriculum for language immersion rooted in the emerging field of linguistic ecology. In the target language, through scaffolded instruction, students will create an inter-related series of annotated data visualizations based on and in support of their linguistic, geographic, and cultural encounter. The goal of this work is to support students in highlighting their own language development, participation, and transformation, and its unconventional visual and instructional scheme invite and inspire celebration of the inter-relatedness, complexity, and beauty of life.

Thermoregulatory and Ventilatory Responses in Humans with a Patent Foramen Ovale During Passive Cooling While Immersed in 40 °C     

James Davis, Human Physiology

►Show Full Abstract

Approximately 35% of the general healthy population has a patent foramen ovale (PFO). People without a PFO (PFO–) have a lower esophageal temperature (Tesoph) than subjects with a PFO (PFO+) during rest. Twenty males (10 PFO+) matched for height, weight, and age participated in this study. Participants sat in a hot tub (40 C) immersed to the neck until 30 minutes had elapsed or Tesoph reached 39.5 C. PFO+ participants had a higher Tesoph and blunted ventilatory responses compared with PFO- participants. These data suggest that PFO+ participants cannot dissipate heat as effectively as PFO- participants during passive heating.

Motivations & Relationships for Local Food Producer Distribution in Eugene, Oregon      

Nicholas Dreher, Environmental Studies

►Show Full Abstract

With the increased attention focused on local food systems, it is important to understand how local food is distributed. In Eugene, local food producers are often visible at stands at the farmers’ market or through their community supported agriculture programs. However, this focus on direct sales obscures the increasing importance of wholesale for local food producers. Through semistructured interviews with producers and wholesale buyers, I explored the decision-making process by which local food producers choose different sales avenues. I also explored the dynamics of their relationships with wholesale buyers to shed light on how producers succeed in the local food system.

Behavioral Interventions for Trichotillomania in Individuals with Developmental Disorders: A Systematic Review      

Christine Drew, Special Education

►Show Full Abstract

Trichotillomania is the recurrent pulling out of one’s hair, resulting in noticeable hair loss that cannot be otherwise accounted for. This behavior causes clinically significant distress and impairment in social, occupational, or other areas of functioning. In developmentally delayed individuals, symptoms can persist with varying levels of severity across the lifespan. After a systematic review of the literature, fourteen studies were evaluated in terms of participants, functional assessment procedures and results, intervention procedures, results of the intervention, and certainty of evidence. Treatments included punishment, response interruption and prevention, reinforcement, and awareness training. Suggestions are offered for future research.

Analog U: A UO Initiative Engages with the Meaning of Digital Connections Through a “Disconnect”       

Emily Fiocco, International Studies

►Show Full Abstract

Analog U is a co-curricular, research-based initiative of the University of Oregon’s Division of Undergraduate Studies. Designed to promote critical awareness of the role of digital technology in our lives, Analog U forges a learning community of faculty and undergraduate students. This community will build a toolbox to activate academic theories of culture, power, communication, and attention. Analog U takes place in classrooms around the university and culminates in spring term with a campus-wide experiential learning opportunity to “disconnect” in order to think deeply about the role of technology and media within our lives.

The Feasibility of Zero Emission Residential Design

Alyssa Franco, Architecture and Nicolette Stauffer, Architecture

►Show Full Abstract

The construction and operation of buildings have a significant impact on global carbon emissions, and schematic design decisions frame the scope of these impacts. This project aims to build off existing zero-emission design studies to test the feasibility of carbon neutrality across multiple climate zones through a process of iterative design and calculation. The energy use of the building and its embodied emissions in the materials are quantified in terms of CO2 equivalent, establishing the amount of on-site energy production needed to offset those emissions. Small modifications, tailored to the specific locations, have a significant impact on the building’s performance.

Measuring Social Capital: The Case for Monkeying Around in Education Research  

Brian Gearin, Education Leadership

►Show Full Abstract

During the 1990s, neoliberal economists and political scientists deracinated the construct of social capital from the structural-functionalist paradigm whence it originated so that it could be included in their own research projects. This process popularized the construct but also led to incoherence in how it is used. Many scholars have come to argue that researchers should abandon the construct of social capital wholesale. This study provides an overview of their criticisms and argues that researchers should examine recent trends in primatology, evolutionary psychology, and the measurement of socioeconomic status as a means of refining or, alternatively, eliminating the concept.

Climate Change Impacts on Four Perennial Forbs in Pacific Northwest Prairies    

Lauren Hendricks, Environmental Studies

►Show Full Abstract

To determine how Pacific Northwest prairies could respond to climate change, I am studying the demography (e.g., fitness and individual plant size) of 16 natural populations of four perennial forb species native to Pacific Northwest prairies. These populations are distributed along a 700-km latitudinal gradient from southern Oregon to Whidbey Island, Washington. In addition to climate variables, I measured many abiotic factors (e.g., soil depth and nutrient availability) to determine the influence of local site factors vs. regional climate. Preliminary analyses suggest that climate is not a strong predictor; instead, local variation is likely responsible for these differences.

Multi-resolution Analysis of Connectivity and Evolution of Huge Graphs  

Soheil Jamshidi, Computer and Information Science

►Show Full Abstract

As networks grow in size and become more informative, more effort is needed to understand them. Analysis of the structure and content of a huge network over time is no longer a trivial task because of the size and rate of changes. Through this research, we investigated different characteristics of a huge network (Google+). By observing the network from multiple resolutions—entire network, community, and node/edge levels—we report in detail the behavior of the network in each level. By leveraging these findings, we can justify the network’s behavior in the past and predict the evolution of its patterns in the future.

Availability of Production-based Representations for Non-native Speech Perception       

Misaki Kato, Linguistics

►Show Full Abstract

Previous studies have suggested a dissociation between a non-native speaker’s ability to produce and to perceive new sounds. However, the cause for this dissociation is unclear. In this study, we examine whether second language (L2) speakers’ production-based representations can also subserve perception. Specifically, we ask if L2 speakers who can reliably produce a difficult sound distinction (e.g., /r/ and /l/ for native Japanese speakers) show the same ability with non-word repetition after explicit visual support or less explicit audio support for their production targets. Results of this study add insight into our understanding of the relationship between representations in speech production and perception.

Economic Decision-Making and Neural Correlates of Value in C. Elegans    

Abraham Katzen, Biology

►Show Full Abstract

The interaction of cost and perceived quality is central to value-based decision making. Such decisions are made by correctly assessing the costs and benefits of two or more courses of action and executing the one offering the highest value relative to the costs incurred. Calculating this trade-off between cost and benefit is critical to any decision between competing options. We found that the nematode worm Caenorhabditis elegans engages in such a cost-benefit analysis when choosing between food options in a decision-making task. We also found that response properties of sensory neurons reflect the subjective value of available options.

Share the Knowledge: Management Research from the Private Sector to the Service-Oriented Sector  

Eren Kavvas, Nonprofit Management

►Show Full Abstract

As the service-oriented sector (nonprofits, social enterprises, B-corps) grows, it takes successful ideas from the private sector and applies them in innovative ways. How has this research dissipated? Looking at academic research from the different sectors, my research studies associations between management research on the private sector and that on the service-oriented sector to find relationships between the two outputs. There is also qualitative post-hoc work looking at the theories where there was a significant relationship to understand how they have shaped the service-oriented sector and, in effect, our society.

Decoding Hierarchical Representations of Complex Sequences from EEG Oscillatory Activity    

Atsushi Kikumoto, Psychology

►Show Full Abstract

Models of serial-order control assume that complex sequences require hierarchical representations, where higher level plans specify the order of subplans/chunks, which in turn organize basic elements. To measure the neural codes underlying such control structures, participants remembered nine-element sequences of orientations constructed from three chunks of three elements each (e.g., abc-bca-cab). Pattern classification analysis of the distribution of oscillatory EEG activity allowed us to independently decode the identity of contents and order of sequences across hierarchical levels. These results suggest that EEG oscillations can be used to characterize the temporal dynamics and cognitive constraints of representational codes of hierarchical sequences.

Associations Between Asynchronous Maternal Responding to Child Autonomy and Children’s Inhibitory Control in High Risk Families    

Carrie Lapsey, Counseling, Family, and Human Services – Prevention Science

►Show Full Abstract

The present study examines the association between asynchronous maternal response to children’s autonomous behaviors and children’s inhibitory control. We hypothesized that greater maternal aversive, nonsynchronous responses to children’s prosocial autonomy predicts lower child inhibitory control. Maternal asynchronous responding was coded using the Structural Analysis of Social Behavior observational coding system during a joint problem-solving task. Child inhibitory control was measured using two Stroop-like tasks and a snack delay paradigm. Multiple regression analyses of one-step mother-child transactions will be conducted and include key covariates (i.e., child age).

Subject Honorifics in Korean Spoken Language: A Sociopragmatic Study   

Keunyoung Lee, East Asian Languages & Literatures

►Show Full Abstract

The Korean language has a highly developed honorific system with rich and varied linguistic elements and features. Although a few syntactic-based studies on Korean honorifics have been conducted, little is known about how Korean native speakers use honorifics in their spontaneous utterances and about the impact of pragmatic and sociolinguistic factors on their choices of honorifics in the utterances. To fill this gap, I examined the referent honorifics in spontaneous conversations by Korean native speakers. I used two major research strategies: (1) a quantitative analysis of spontaneous spoken corpus data and (2) a qualitative discourse analysis. I propose that Korean honorifics is one of the pragmatic linguistic devices not controlled by syntactic agreement and involves various sociolinguistic factors such as social deixis and distance and gender.

The role of Peer Racism on Ethnic Identity in Mixed Race Adolescents        

Steve Livingston, Counseling Psychology

►Show Full Abstract

The number of individuals who identify as mixed race or multiethnic has been consistently increasing across the world. This noticeable change in the ethnic makeup of our society has led to more research focusing on ethnic identity in mixed-race adolescents. However, the effects of peer racism on ethnic identity in mixed-race adolescents has not been well studied. This knowledge gap is concerning because the development of one’s ethnic identity is at a critical stage during adolescence. I am focusing my research on the role of peer racism on ethnic identity in mixed-race adolescents.

Planfulness – Individual Differences in Goal Strategies

Rita Ludwig, Psychology

►Show Full Abstract

Planfulness describes an innovative way to measure an individual’s likelihood of achieving a desired goal. Previous literature suggests that specific ways of thinking about goals can predict achievement. Planfulness extends these findings by representing an individual-differences measurement of the propensity to engage in beneficial habits of thought about goals, which can then be used to predict the likelihood of achievement. The current work presents the development of a scale to measure planfulness in the general population. Data from five studies and over 3,000 participants support the Planfulness Scale as a valid and reliable metric, and research on predictability is ongoing.

A College Marijuana Survey: A Summary of Usage, Social Norms, and Perceived Consequences of Getting High

Jake Mahon, Social Psychology & Special Education

►Show Full Abstract

The University of Oregon’s CommUniversity program, within the Dean of Students office, teamed up with the UO’s Prevention Science Institute to capture students’ thoughts about using marijuana. Nearly 6,000 students (25% of the UO student population) responded to a 180-item survey in exchange for the chance to win a gift card to the university book store. This study reports on UO student marijuana usage, student perceptions of typical use on campus, and the perceived effect that marijuana use has on one’s academic and other life success. Risky behaviors associated with marijuana use are discussed.

Context-specific Syllable Co-occurrence Probabilities in Infant-Directed Speech

Rose Maier, Psychology

►Show Full Abstract

People talk about coherent episodes of their experience, leading to strong dependencies between words and the contexts in which they appear. Here, we ask whether this fact also yields context-specific distributions of transitional probabilities between syllables—a statistic hypothesized to help learners discover words in the first place. This issue is important because the status of transitional probabilities as a cue to word segmentation in infant-directed speech is unclear. We consider the transitional probabilities available within typical contexts (e.g., mealtime, diaper change, and bedtime) sampled from a large corpus of infant-directed speech. The distribution of these probabilities within each context differs significantly from size-matched “nontexts” randomly sampled from the same corpus. Word boundaries may be clearer within context because frequent syllables (e.g., milk) co-occur with a range of subsequent syllables (milk hmm, milk to, milk in) in that context. The structure provided by coherent contexts may allow learners to use a cue that may not otherwise rise as signal out of noise in the full complexity of infant-directed speech.

Engaging international Students in the U.S. university experience

Annelise Marshall, Linguistics

►Show Full Abstract

This year, over 1 million international students came to study in the United States. While improvement in English is a primary motivation for many of these students, they also want a study abroad experience; however, many students struggle to engage with the home university outside of class. Based on surveys and interviews with faculty and with students for whom English is a second language, this project will identify the engagement goals of international students and how these goals are or are not met. I also will present a materials portfolio of lessons designed to foster student engagement with the larger university culture.

Graduate Student Career Center Services    

Colleen McCarthy, Counseling Psychology

►Show Full Abstract

The needs of graduate students are unique and complex. As the world of careers is adapting and changing, the importance of relevant and effective career services is growing. I outline best practices in career services and relevant services that the University of Oregon Career Center offers graduate students and seek to gather data about how the Career Center can best meet graduate student needs.

Do Religious Beliefs Influence Support for Government Redistribution of Income? 

Brett Mercier, Psychology

►Show Full Abstract

Past research has found that religiosity tends to be associated with decreased support for government redistribution of income. In this study, we experimentally tested whether this is a causal relationship. Across three different experiments using different methodologies, we found no evidence that religion influences support for government redistribution. In studies 1 and 2, religious priming did not affect support for government redistribution. In study 3, reading Bible verses related to justice did not affect Christian participants’ support for redistribution, despite increasing the belief that God is enforcing justice.

The Mexican Border Fence as Architecture and Its Consequences  

Mason Moorman, Art History

►Show Full Abstract

The Mexican Border Fence that runs along the border between the United States and Mexico has yet to be studied through the lens of art history. In considering the Border Fence as architecture, I open the discussion up to a wide breath of architectural theory, especially that dealing with the use of phenomenology, or the philosophical study of experience. Through a study of the Border Fence design in comparison to the Israeli Barrier Wall and its phenomenological consequences, I find new means of understanding the Border Fence’s significance and a greater understanding of architecture.

Dissecting Twitter Elites       

Reza Motamedi, Computer and Information Science

►Show Full Abstract

We conducted a detailed analysis of the macro- and micro-level structure of the Twitter elite network at different sizes. The Twitter elite network has a similar star-shaped structure at different sizes where 90% of its nodes form the largest strongly connected component (LSCC) in the center. The LSCC is composed of a number of resilient communities that exhibit strong social cohesion. Examination of the pairwise tightness between these communities revealed the coarse structure (and level of interest) among these communities. Exploring the aggregate influence of individual elites on the rest of the elite network based on three different measures, we found that each measure identifies different types of influential users.

Time is of the Essence: Establishing Chronological Baselines for Archaeological Research in the Florida Keys

Matthew Napolitano, Anthropology

►Show Full Abstract

The Florida Keys are among the most archaeologically rich but highly threatened coastal areas of North America. The archaeological record in the Keys is vulnerable to development, natural catastrophes, and sea level rise, but a dearth of both field research and high-resolution radiocarbon chronologies have created substantial challenges to understanding the age and extent of prehistoric settlement. In this study, I examined historically collected shell specimens housed in museums to determine local marine reservoir corrections necessary for adjusting the calibration of radiocarbon dates. Results show wide variability and provide a mechanism for determining the age of sites, including those at risk for erosion and inundation.

Examining Spatiotemporal Variability of Twitter Data Representativeness          

Rudy Omri, Geography

►Show Full Abstract

Social media have increased the amount of citizen-based data production, garnering interest in various Big Data research. Social media data are often used in visualizing public opinion regarding a particular event. The goal of this research is to evaluate and characterize the spatiotemporal variability of sampled data representativeness that is voluntarily submitted through Twitter. A case study is selected – public approval of President Barack Obama’s presidential performance – and we utilize Twitter API to generate sampled tweets. The collected Twitter data will be analyzed to determine their individual geographic location and sentiment polarity. The aggregated results of the analysis will be compared to the results from statistically-represented public opinion polls such as Gallup and Pew Research Center. The anticipated outcome of this research is the degree of representativeness of Twitter data for each state in the contiguous United States. The measure of representativeness can be attributed as the departure of Twitter data sentiments from the sentiments surveyed from public opinion polls. The findings may be useful in determining whether tweets can be used as reliable data source in research methods especially in geography. This project also aims to assess whether Twitter data can be a germane alternative for the public opinion polls mentioned above.

The Application of Linguistics Theory in Language Pedagogy – A Constructionist Approach to Language Teaching

Xinjia Peng, East Asian Languages and Literatures

►Show Full Abstract

Construction Grammar is a relatively new linguistic theory that sees language as composed of noncompositional form-meaning mappings, or “constructions.” I will demonstrate how to utilize the concept of “construction” by drawing on general cognitive principles such as prototype effect, frequency effect, and saliency to develop effective pedagogical activities, especially teaching materials that facilitate foreign language learning at different proficiency levels.

Short-term Muscle Adaptation to a Rigid Ankle-Foot Orthotic       

Shannon Pomeroy, Human Physiology

►Show Full Abstract

Ankle-foot orthotics (AFOs) are used for a variety of ailments in the population to restrict movement at the ankle. However, their negative effects on the rest of the body as it adapts to the altered walking patterns are not well understood. This work aims to observe muscle activation and joint motion patterns during a short-term introduction to a rigid AFO in healthy individuals. Applications of the findings will include better service of clinical populations in therapy practices, such as patients with end-stage ankle arthritis, and prevention of long-term problems in the surrounding joint following the limited ankle range of motion.

Functional Genetic Cis-Regulatory Element Identification in Innate Immune Response   

Melissa Randel, Biology

►Show Full Abstract

The Drosophila innate immune system can mount rapid responses to bacterial infection through activation of the Toll and IMD pathways, which work to activate expression of antimicrobial peptides tailored to the specific pathogen. Our method identifies functional genetic cis-regulatory elements (CREs), which modulate gene expression in response to pathogen challenge. This assay has the potential to identify every CRE in the genome in a single assay in a functional context: only CREs involved in pathogen response are identified. In conjunction with RNA interference of transcription factors, this method can be used to determine binding specificities of CREs.

A group of 870 Latina/o high school students (age 14-20 years; 64% identified as female, and 54% identified as male) attending a Latina/o leadership conference at a state university in the Pacific Northwest completed surveys, in either Spanish or English, that included one open-ended question: “How do you think that Latina and Latino young people can make a difference in our communities?” The written qualitative responses of the 870 students were transcribed, coded, and analyzed by a team using aspects of Grounded Theory, Consensual Qualitative Research, and Thematic Analysis. The research team discovered four primary categories: education, advocacy, culture, and community involvement. Within each category, specific themes emerged from the data. For example, within the category of advocacy, one theme was “In order to make a difference in our communities, it is important to advocate together (unity).” All themes will be presented in detail.

A study of Ripples: Investigating Information Propagation in Google+      

Seyedsaed Rezayidemne, Computer and Information Science

►Show Full Abstract

Word-of-mouth (WOM) communication is a well-studied phenomenon, and content propagation in online social networks (OSNs) is a form of WOM. The goal of this study is to characterize the content propagation in Google+, which is one of the major OSNs. This study is focused on a natural language processing problem, where the topic or sentiment of posts cause message diffusion. However, the propagation can be the effect of graph properties, i.e., popularity of message originators or activities of communities. Having these complimentary views allows us to gain better insight into the problem.

The Learning Arcade Platform: Tiered Instruction and Data-Based Feedback        

Rachel Santiago, School Psychology

►Show Full Abstract

Educational technology, including applications (apps), has increased in popularity and prevalence in recent years. Although resources exist to help teachers discover engaging or standards-aligned content, little work has been done to quantitatively examine app efficacy. The Learning Arcade, an efficacy-driven platform of rigorously tested apps that allow educators to support student outcomes, has been developed to address the need to align educational technology and authentic instructional practices. Participants will learn how the platform meets growing instructional design needs, explore how the platform can support data-based decision making and tiered instruction, and examine platform feasibility and usability based on pilot study findings.

Brain Function for Selective Attention in Bilingual Adults

Jimena Santillán, Psychology

►Show Full Abstract

Neuroscientific evidence suggests that the extensive experience bilingual individuals have managing two languages gives rise to differences in brain structure and function. The present study employed a technique to measure electrical brain responses to examine selective attention in Spanish-English bilingual adults. Participants completed an auditory selective attention task in which they were simultaneously presented with two different narrative stories and were asked to attend to one story while ignoring the other. Brain responses were elicited by identical sound probes embedded in both narratives. Responses to the probes in the attended story were compared with the responses to the probes in the unattended story.

Is Technology the Answer?

Rachael Schuetz, Educational Leadership

►Show Full Abstract

With millions invested in educational technology, what is its impact on student achievement and engagement? A review of the literature and a sequential mixed-methods experiment were conducted to examine the effects of an iPad-based math intervention compared with a traditional paper-pencil approach on achievement and engagement in mathematics among students in grade 2. Quantitative pre- and post-study assessments include one engagement and two achievement measures. Qualitative focus group data from the teacher perspective provide a complete view of student engagement. With finite intervention time and resources, schools need to know how to best improve student achievement and engagement in mathematics.

Locating the Best Collaborators to Defend DDoS Attack

Lumin Shi, Computer and Information Science

►Show Full Abstract

Researchers have spent years trying to defeat distributed denial-of-service (DDoS) attacks, and the most promising method is to have Internet service providers (ISPs) participate in the defense. This distributed method can stop traffic closest to the source, and the closer an ISP is to the attacker, the less cost one will incur. However, this method is facing a fundamental challenge: How can we find the ISPs that can best stop the attack flows? This work will focus on the strategies for finding the right ISPs for each attack flow and for using this knowledge for DDoS defense.

Automated Analysis of Complex Animal Behavior

Sarah Stednitz, Biology

►Show Full Abstract

Automated behavioral analysis is an increasingly important component of high-throughput research in neuroscience and pharmacology. Many existing software suites are closed source, reducing accessibility and introducing a black box that limits troubleshooting or innovation. To address this issue, I have developed an open source software package (DaniOpen) designed for rapid, high-throughput screening and on-the-fly data analysis and electronics control. I present a novel analysis of complex social behaviors in zebrafish (Danio rerio) using this software.

Exploring the Algorithmic Logic Establishing Neuroarchitecture in Drosophila        

Luis Sullivan, Biology

►Show Full Abstract

Developmental algorithms are central to the formation of neural circuits. These algorithms simplify the assembly of neural circuits to fundamental rules and principles. Drosophila has emerged as a powerful model organism to define the genetic machinery generating neural diversity and assembly of neural circuitry. Highly conserved transcription factors (TFs) play a key role in both events.  For the generation of neural diversity, neural progenitors express a sequential series of TFs as they asymmetrically divide into neural progeny, a mechanism referred to as temporal patterning. Whether this information incorporates into a developmental algorithm for assembly of neural circuitry is unclear.

What’s in a Name? Identity Creation as Shaped by Americanized Name Adoption

J.D. Swerzenski, Media Studies

►Show Full Abstract

For all the many facets of cultural assimilation, few are more noticeable than name change. As more immigrants from African and East Asian backgrounds enter the American citizenry, new linguistic and cultural barriers to assimilation have emerged. This study investigates this emergence through the stories of immigrant students who have adopted Americanized names, exploring their reasons for taking on a different name and the negotiation of their identities around their birth and adopted names. A linguistic analysis of attempts by American students to pronounce the birth names of the immigrant students studied will be conducted to offer a counterpoint.

Reconciling Recent Approaches to Voice Leading in Atonal Music  

Dale Tovar, Music Theory

►Show Full Abstract

It is sometimes difficult to make progress in voice leading theory when there is a fundamental disagreement on the exact definition and general nature of the subject. What exactly is a voice? Is a voice a perceptual or theoretical entity? Is voice leading a homophonic or linear concept? This study answers these questions by forming a coherent, generalized definition of a voice and a methodology that aids in both discussion and application. The analytic utility of this system is demonstrated by an analysis of an early atonal work of Alban Berg.

Large-Scale Imaging of Cortical Dynamics During Sensory Perception and Behavior          

Joseph Wekselblatt, Biology

►Show Full Abstract

Sensory-driven behaviors engage a cascade of cortical regions in the brain to process sensory input and generate motor output. To investigate the temporal dynamics of neural activity at this global scale, we have developed methods to perform functional imaging across large areas of cerebral cortex. This technique allows imaging of activity across the dorsal surface of the cortex at a spatial resolution of approximately 50 μm and a temporal resolution of approximately 100 msec. This approach will be useful for probing information flow and network processing in brain-wide circuits involved in many sensory and cognitive processes.

The Goddess of Democracy And The Tiananmen Protest: An Instrument Of Declaration, Demonstration And Unification        

Kun Xie, Art History

►Show Full Abstract

The original statue of the Goddess of Democracy was erected during the later stage of the Tiananmen Incident as a visual recapitulation of the student protest. Its visual-cultural tradition was largely inspired by earlier Chinese social-realism while taking the gestural form of the Statue of Liberty. The statue’s symbolic and short-lived existence functioned as the ultimate visual expression and provocation of the students’ resolve. Its ideology of democracy, with which the statue was embedded, was to advocate a vernacular political concept. The Goddess was personified by the students as the bringer of democracy to posterity in China.

Characterising Traffic Footprint of a Stub-AS          

Bahador Yeganeh, Computer and Information Science

►Show Full Abstract

A rich and very dynamic content distribution ecosystem enables today’s Internet users to access content associated with major providers from a close-by server. Although the end goal of content locality is to increase user performance, the interplay of many factors such as route changes, link congestion, server overload, and user connection type could affect the end result. The aim of this study is to measure the level of content locality that an end user observes and to characterize and identify factors that affect the performance that users experience.

Identification of Individual Differences in Reading Comprehension Processes      

HyeonJin Yoon, Educational Leadership

►Show Full Abstract

The purpose of this study was to identify individual differences in the types of comprehension processes used during reading. The Latent Class Analysis of think-aloud responses from students in grades 3 through 5 (n = 88) identified two distinct subgroups of readers. Students in class 1 made more associations, elaborative and predictive inferences, questions relevant to the texts, and meta-cognitive and evaluative comments. Students in class 2 tended to paraphrase or repeat verbatim the text. These findings support the heterogeneity of comprehension processes during reading. Potential predictors of class membership and implications of the findings are discussed.

Game-Theory-Based DDoS Defense Strategy Study

Mingwei Zhang, Computer and Information Science

►Show Full Abstract

Distributed denial-of-service (DDoS) attacks have been plaguing the Internet for decades. Many projects have been proposed to stop the DDoS attacks collaboratively; however, none have been deployed on the Internet. Internet service providers and other large organizations do not have enough motivation to deploy such DDoS defense solutions. In this project, we use a game-theory–based approach to formalize the relationship between the cost of DDoS defense solutions and the revenue of the organizations, motivating organizations to deploy collaborative defense solutions. This project is among the first to shed light on the motivation of organizations to defend against DDoS attacks.

The Language of Images in Heiner Müllers Drama 

Nora Zimmermann, German

►Show Full Abstract

Heiner Müller is considered the most important German Democratic Republic dramatist after Bertolt Brecht and is well known for his socialist ideals but also critical attitude toward dominant ideologies. In his play Mauser, Müller elaborates on the concept of Brecht’s learning plays (Lehrstück). Surprisingly, Müller decides to abandon this approach shortly thereafter. His later plays favor a reprise of classical drama such as Shakespeare or Greek tragedy and the usage of mythical images. In this presentation, I investigate the specific function of literary images in Müller‘s plays Mauser and Medea and therein his critique of civilization.
