Visualization Of Eye Development In Annual Killifish Using Whole-Mount Immunohistochemistry, Carmen Z. Rodriguez, Jason Podrabsky

Student Research Symposium

Vertebrate eye development is highly conserved. Current models have identified the gene networks involved in eye development, but lack the context of extreme environmental conditions that challenge these fundamental programs. Typical vertebrates live for many years while annual killifishes can complete their entire adult lifespan in a matter of weeks. Thus, annual killifishes are a strong model for age-related diseases such as age-related macular degeneration (AMD); an irreversible loss of central vision. Annual killifishes enter embryonic diapause; a period of developmental and metabolic dormancy. These embryos are extremely resistant to environmental stresses such as hypoxia/anoxia that would cause irreparable damage …

Exploring The Function Of Heart Regeneration In Survival Of Anoxia In Embryos Of The Annual Killifish Austrofundulus Limnaeus, Connor Taylor Kime

Student Research Symposium

Cardiovascular disease is the leading cause of death in the world, half of which is caused by myocardial infarction (MI) or heart attack. Most of the damage resulting from MI is due to oxygen deprivation that leads to cell death. The resulting cardiac scarring due to MI is chronic in humans and is not yet treatable; the only method of restoration is heart transplantation. Other organisms, such as fishes, show great cardiac regenerative capacity. The annual killifish, Austrofundulus limnaeus, can survive for months without oxygen at certain developmental stages. Examining gene expression responses during anoxic exposure and recovery in …

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

Student Research Symposium

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

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

Student Research Symposium

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

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

Student Research Symposium

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

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

Student Research Symposium

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

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

Student Research Symposium

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

Patterns Of And Experiences With Dysphagia In People With Hypermobile Ehlers Danlos Syndrome (Heds) With Or Without Dysautonomia, Karyssa A. Stonick, Deanna Britton Dr., Emily Goble, Alison Wong, Alena Guggenheim Dr., Donna Graville

Student Research Symposium

Ehlers Danlos Syndromes (EDS) are collagen-based hereditary connective tissue disorders characterized by decreased tissue integrity. Historically, the musculoskeletal and dermatological manifestations have been emphasized. However, EDS is associated with symptoms and conditions affecting nearly all body systems, including swallowing (dysphagia). A Cohort Discovery analysis at Oregon Health & Science University (OHSU) revealed that 14.9% ± 0.3% of patients with an ICD-10 diagnosis of EDS also have an ICD-10 diagnosis of dysphagia in their medical record. Despite only one article in the current literature, the prevalence of dysphagia in EDS is not insignificant and warrants further investigation. Our long-term hypothesis is …

Global Governance Or Global Government? An Examination Of Anarchy Vs. Hierarchy, Global Civil Society And International Governmental Organizations, Grace R. Purvis

University Honors Theses

The goal of this paper is to argue that we currently have a system of global government rather than global governance. To prove this, It examines two main areas, international hierarchy and global society. In terms of hierarchy, it considers the existence of hierarchy among nations as well as a practical hierarchy in global decision making and functioning. This is shown via an examination of American Empire, Power Transition Theory, the Washington Consensus, the United Nations and the North Atlantic Treaty Organization. The second major focus, global society, considers how nations utilize international organizations and technology to allow for the …

A Multi-Species Study On Several Types Of Visitor Effects On The Behavior And Physiology Of Animals At The Oregon Zoo, Laurel Berylline Fink

Dissertations and Theses

The visitor effect on zoo animals is one of the expanding research topics in zoo animal research. As visitors are a mandatory feature of zoological institutions, understanding their effects on zoo animals is imperative for maximizing zoo animal welfare. Zoo animals are subject to many anthropogenic influences: visual, olfactory, and audible, for example. This dissertation investigates several of the effects of visitor presence and its relative influence on six mammalian species: cheetahs (Acinonyx jubatus), African painted dogs (Lycaon pictus), Asian elephants (Elephas maximus indicus & Elephas maximus borneensis), giraffes (Giraffa camelopardalis reticulata & …

Who Is On The Bandwagon? Core And Periphery In Mixed Methods Research, David L. Morgan

Sociology Faculty Publications and Presentations

The rapid growth of mixed methods research over the past two decades matches what Fujimura (1989) called a “bandwagon effect.” This study compares articles from the Journal of Mixed Methods Research, representing the core of the field, to a more peripheral set of randomly drawn articles. A content analysis of the two sets of articles shows strong differences, with the random sample dominated by convergent designs and lower integration between the qualitative and quantitative results. This research contributes to the field of mixed methods by showing systematic differences between articles published in its flagship journal versus a broad sample of …

Black Carbon Dominated Dust In Recent Radiative Forcing On Rocky Mountain Snowpacks, Kelly E. Gleason, Joseph R. Mcconnell, Monica M. Arienzo, Graham Sexstone, Stefan Rahimi

Environmental Science and Management Faculty Publications and Presentations

The vast majority of surface water resources in the semi-arid western United States start as winter snowpack. Solar radiation is a primary driver of snowmelt, making snowpack water resources especially sensitive to even small increases in concentrations of light absorbing particles such as mineral dust and combustion-related black carbon (BC). Here we show, using fresh snow measurements and snowpack modeling at 51 widely distributed sites in the Rocky Mountain region, that BC dominated impurity-driven radiative forcing in 2018. BC contributed three times more radiative forcing on average than dust, and up to 17 times more at individual locations. Evaluation of …

Proposed Application For An Entity Component System In An Energy Services Interface, Tylor Slay, Grace B. Spitzer, Robert B. Bass

Electrical and Computer Engineering Faculty Publications and Presentations

An Entity Component System is a data-oriented architecture originally developed to streamline video game performance. Despite being quite new, Entity Component Systems are relatively well established within the video game industry due to the cutting edge nature of research into performance, especially around graphics. However, Entity Component Systems have not been widely examined or adopted outside of that industry. We propose adopting an Entity Component Systems framework to serve the needs of an Energy Service Interfaces. We examine the needs of an Energy Service Interface, give an overview of open-source Entity Component Systems (ECSs) libraries, examine some preliminary performance results …

Randomized, Clinical Trials On The Effects Of Robotic-Assisted Gait Training For Stroke Subjects: A Scoping Review, Daniel K. Hufnagel

University Honors Theses

Robotic-assisted gait training has been cited as a potential rehabilitation intervention for the recovery of ambulation in hemiplegic stroke patients. Previous reviews on robotic gait training have elicited a need for more randomized, clinical studies on robotic gait training for the development of evidence-based intervention protocols and elimination of research bias. The purpose of this scoping review was to provide an updated examination of the clinical research on robotic assisted gait training and address any research gaps to be considered for future research. This review included randomized, clinical trials on stroke patients with a robotic-assisted treatment (RAGT) and conventional gait …

Schism And Suppression: Early Threats To The Esperanto Language, And Resulting Impacts On International Acceptance, Anabel E. Cull

Young Historians Conference

The constructed language of Esperanto, created by Polish linguist Ludovic Lazarus Zamenhof in 1887, was founded with the intention of facilitating global peace and unification. Due to the mission and philosophy of the language, known as Esperantism, Zamenhof’s invention gained popularity among political reformers and communities facing religious discrimination. Aiming to resolve conflict through common language, Esperantism inspired hope amidst the increasingly oppressive social and political climate present in Eastern Europe and Russia during the early 1900’s. This paper explores the contributing factors to Esperanto’s decline, and the impact of internal conflict, political affiliation, and religious significance on efforts to …

Operation Mincemeat: The Impact And Influence Of Wwii’S Most Daring Intelligence Operation, Maya N. Dasilva

Young Historians Conference

In 1943, during the height of the Second World War, the dead body of a man in his early thirties was released from HMS Seraph submarine off the southwest coast of Spain. This corpse carried fabricated letters outlining the Allies’ plan to attack Greece and Sardinia which convinced German forces to defend Greece and move away from the real target, Sicily. This successful, radical, and deceptive operation led by Ewen Montegue to disguise the Allied Invasion of Sicily using false-intelligence tactics forwarded the Allied victory and increased the prevalence of deception in war. This paper explores Operation Mincemeat’s revolutionary nature, …

Qur’An And Constitutions: Sharia In Modern Muslim Democracies, Adrian N. Vasquez

Young Historians Conference

In contemporary society there has seen a gradual shift in the politics of the Muslim world toward more democratic constitutions. This shift can be seen in the aftermath of successful uprisings in Tunisia and Egypt during the Arab Spring as well as isolated cases in other countries. The change echoes those that resulted from the Protestant Reformation’s challenge of the Catholic Church’s authority in 16th century European politics. By looking at the ideas of early constitutionalism in Europe that supported liberalism, it is possible to compare those with the goals of constitutions of new Muslim democracies. Though in many cases …

Keeping In Touch While Sheltering In Place: A Comparative Case Study On The Complex Emotions Experienced By Older Adults When Introduced To Icts And Video Conferencing Services, Marisa Susan Soltz

Dissertations and Theses

Currently, COVID-19 poses a threat to the US and the rest of the world, which has created the need for many people to establish physical distance from others. This need for physical distance is perhaps most important for those most vulnerable to COVID-19, which includes the older adult population. Through this time of physical isolation, most people need to keep in touch with each other while sheltering in place. Advances in digital communication have offered new avenues to help people maintain communication, and these advances have made the lives of many easier and more efficient. These new avenues for communication …

The Meaning And Measure Of Deliberative Systems, Darren Michael Mccormick

Dissertations and Theses

Deliberative democratic theory emphasizes deliberation as central to the health of democracy. It has grown to be one of the most active and popular stands of political theory. In response to criticisms that deliberative democracy was unworkable at the large scale, the field made a systemic turn and now conceives of political communities as potential deliberative systems. While advancements have been made in measuring the quality of deliberation that occurs in deliberative forums, the practice of measuring the quality of deliberative systems is in its infancy. Authors have proposed various theoretical paths to assessing deliberative systems but no standardized method …

Anthropology Faculty Publications and Presentations

Indigenous Peoples’ lives, cultures, and values are defined largely by their long-term relationships with the lands, waters, and lifeforms of their territories. Their stories, names, ceremonies, and connections with the plants and animals on which they have depended over countless generations are cornerstones of their knowledge systems, systems of governance and decision-making, traditions of intergenerational knowledge transmission, and values and responsibilities associated with natural and human domains alike. For First Nations of North America’s Northwest Coast, as for many other Indigenous Peoples, the arrival of European newcomers disrupted both the natural world and associated cultural practices in interconnected ways. The …
