Chronic gastroesophageal reflux is a common contributing factor to dysphagia. Consequently, dysphagia treatment often includes discussion and education regarding behavioral management strategies and dietary modification to prevent reflux, including the provision of written materials to encourage follow-through. The goal of the current project was to revise and update the existing evidence-based pamphlet of behavioral modifications to manage reflux being used at Oregon Health & Science University (OHSU), including the addition of non-pharmaceutical beverage and homeopathic alternatives to reduce reflux and soothe gastrointestinal (GI) tissues. A scoping literature search was conducted during the period from June 2021 to March 2022 via …

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 …

Making Use Of Prosodic Resources In A New Language: Self-Repetition In Wh-Questions In Talk-In-Interaction, Phoebe Cordova

PSU McNair Scholars Online Journal

There is a growing body of research being conducted on L2 prosodic acquisition, production, and variation. Studies have analyzed data from a variety of L1s and have primarily focused on the impact of age of acquisition and proficiency level on L2 prosody. Additionally, almost all of these studies have investigated this area from a phonological approach, using spoken language elicited in highly controlled experimental settings with weak ecological validity. In contrast, this study collected naturalistic language data of an L1 Mandarin speaker of English and incorporated both a phonological and interactional approach to gain a more complete understanding of L2 …

The Connections Between Innovation, Culture, And Expertise In Water Infrastructure Organizations, Alice Brawley-Chesworth

Dissertations and Theses

Infrastructure organizations are notoriously conservative and resistant to change, even when faced with wicked problems that cannot be solved with the same thinking used in the past. In the water sector, this resistance to change has been linked to an industry culture that is based in a single, engineering-oriented knowledge system. Scholars have suggested that diversification of knowledge systems is necessary for implementation of innovations that will move the sector forward to solve wicked problems.

This research used a qualitative case study approach comparing two water sector organizations in Portland, Oregon. One organization included members who shared an engineering knowledge …

Building A Turbulent Jet: Measuring/Modeling Lagrangian Dispersion, Particle Trajectory Dynamics And Intermittency, Bianca Fontanin Viggiano

Dissertations and Theses

The mechanics of how particles diffuse, interact, eject, etc. within a fluid is applicable to numerous industrial and environmental applications. Unwanted products of combustion, dust contamination of solar panels, pathogen transport during a cough and ejections of particles during volcanic eruptions, are a few examples of flows in which increased knowledge of particle dynamics could result in substantial reduction of negative environmental and economic impacts. To better understand the tendencies of particles within shearing flows (such as jets), an extensive experimental campaign was conducted. Measurements of a turbulent round water jet were performed within an icosahedral tank. Particle tracking velocimetry …

The Plant Water Management Experiments, Marc Benjamin Wasserman

Dissertations and Theses

A simple means of watering plants in the low-g environment aboard orbiting spacecraft is not obvious. Since the beginning of spaceflight, numerous approaches have been pursued to water plants that seek to maximize plant viability and system reliability, while minimizing crew time and system complexity. The Plant Water Management experiments (PWM) seek to apply recent advances in low-gravity capillary fluidics to the challenges faced during plant growth operations aboard spacecraft. One primary challenge encountered in such applications is to establish Earth-like flows, minimizing the low-g specific adaptations required by the plants. This is difficult due to the fluid physics challenges …

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 …

The Troubles: Root Causes Of Tension In Northern Ireland, Eleanor M. Snyder

Young Historians Conference

Since the first British invasion of Ireland in the 12th century, the native Irish people have been negatively affected by British presence and rule. When the English first set out to conquer Ireland, they did so on the notion and basis of religion, aiming to anglicize the Irish people. The ramifications of creating a class of people, who were second to the British colonizers, have remained persistent throughout history and into present times. The modern culmination of this historical conflict occurred in the 1960’s during the time of the Troubles. However, this Northern Irish conflict was not divided on theological …

Bad Blood: Hemophilia And It’S Detriment To The Russian Imperial Family, Tessia A. Hoffman

Young Historians Conference

Monarchies have often defined the flow of history. Their decisions and ideas affect whole countries, which can lead to a crisis if the ruler is unable to lead effectively. A lack of leadership can bring about war, famine, political instability, and political unrest, all of which occurred in Russia during the 19th and 20th centuries. The poor decision-making of Tsar Nicholas II and Tsarina Alexandra brought about civic unrest that eventually led to their downfall. In addition to the unstable country, the Imperial family was also struggling with the state of their only heir, who had inherited the genetic disorder …

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 …

Fortunate People In A Fortunate Land: Dwelling And Residential Alienation In Santa Monica's Rent-Controlled Housing, Lauren E.M. Everett

Dissertations and Theses

The importance of safe and stable housing for individual and community wellbeing is widely acknowledged. However, for the one third of Americans who rent their homes, housing-related stress and precarity (residential alienation) may undermine stability and a sense of home. Rent control is perhaps the most well-known tenant protection policy in the United States, but it remains highly controversial and its efficacy has been debated for decades. This research is the first academic inquiry to examine the policy through the experience of residents of rent-controlled housing. In academic discourse dominated by quantitative inquiry from the discipline of economics, this study …

Interwar Weimar Film And Masculinity: Challenging The Presumed Crisis Of Interwar German Gender Discourse From Selected Films From 1925-1931, Brandon Metcalf

Dissertations and Theses

The First World War altered the view of masculinity held by many in Germany and shredded what many regarded as unchangeable fixtures of German life. For German men, much of the interwar period meant dealing with the losses from the war, reconfiguring what it meant to be a man. This reconfiguration of gender took place in a context of change in Germany. Many women entered the workforce to replace the lost men. The economic downturn and reliance on funding from the United States motivated many within Germany to examine gender roles and to reassemble masculinity to meet changing circumstances.

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 …

An Investigation Into Magnetic Gears And Magnetic Springs For Marine Hydrokinetic Power Generators, Hossein Baninajar

Dissertations and Theses

Marine hydrokinetic generators often use mechanical gears to convert the low-speed motion into the high-speed rotary motion that is required for conventional electrical generators. While mechanical gearboxes have a high torque density and can reach high efficiencies, they suffer from serious reliability issues. Recently, magnetic gearing technology has been proposed as a means of making hydrokinetic generators more reliable. As magnetic gears use magnetic field modulation to create speed change, they offer a high reliability, nonfriction, power transmission mechanism that limits the wear to only the bearings and makes the magnetic gears almost maintenance-free. During an over-torque condition, a magnetic …

Stakeholder Participation And Influence At State Public Utility Commissions, Genevieve Theresa Kruse

Dissertations and Theses

Despite the international consensus that climate change is a problem, few substantive policies are being pushed forward at the national level to meet international greenhouse gas reduction commitments under the Paris Agreement. The most significant climate change policies are emerging at state public utility commissions (PUCs). While PUCs were traditionally structured to regulate utilities, state PUCs are now finding themselves at the hub for renewable energy, clean energy, and distributed energy policies. Despite the increase in renewable and clean energy policies at state PUCs, there is a noticeably small environmental and clean energy stakeholder presence at those PUC proceedings. A …

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 …

Maturity Model For Customer-Centric Approach In Enterprise: The Case Of E-Commerce And Online Retail Industry, Soheil Zarrin

Dissertations and Theses

The network technologies are changing the dynamics of the interaction between customer and provider. Customers demand closer relationships and higher investment between partners, as well as cooperation between companies to build supporting technologies for their unique needs. Customer-centricity is defined as interaction with the customer through various touchpoints and aggregating these relations to create a position for the customer. Each Customer has a different need and expectation from the provider or seller, and companies need to be flexible enough to fulfill their needs. One of the reasons organizations invest less in customer experience is that they believe they are already …

Improvement Science: Improving Employee Engagement, Ryan S. Carpenter

Dissertations and Theses

Improving employee engagement has proven elusive in too many schools and districts in our nation, persistently contributing to high staff turnover in buildings and limited employee ownership in the mission, vision, and values of a school's strategic plan. The most common approach to the improvement of educational systems has been the adoption of top-down reforms and short-lived improvement programs. In recent years, an Improvement Science approach, which originated in the medical and business worlds, has made its way onto the education scene. The impact of Improvement Science in education is a developing area in educational research. This dissertation includes four …

The Benefits Of Social Support On Health And Well-Being In Military Populations: Examining Mechanisms, Source Of Support, And The Reach Of A Workplace Well-Being Intervention, Annamarie Sophia O'Neill

Dissertations and Theses

Social connection is essential for health and well-being. Although the salubrious effects of social relationships have been established, important questions remain such as: the mechanisms driving these beneficial effects, the extent that promoting social support in the workplace can benefit workers and their romantic partners, and if support from important but less close sources of support (like supervisors) can offer additional health benefits beyond support from closer relationships (like romantic partners). Over three studies, I explored these topics in the context of military couples (Studies 1 & 2) and in partnered service members (Study 3) on health and well-being outcomes …
