How Does How We Learn Influence What We Learn And From Whom We Learn: The Case Of Igen, Twitter, Bts Army, And Learning With Technology, Yuliya Dmitriyevna Goss

Dissertations and Theses

Digital information is omnipresent, and access is almost unavoidable. Technology advances and comes at us in waves that take over and then tend to linger. iGen is the first generation to be born into this advanced technology and the state of constant “plugged-inness” to the Internet. iGen has not experienced a different, predominantly analog, world, but baby boomers, generation X, and millennials – many of whom now use Internet-connected technology heavily – can attest to how they have changed as it integrated into their lives. Along with many other areas of life, learning has also changed with technological progress. From …

Smoking Behaviors In Patients Offered Lung Cancer Screening, Sara Elizabeth Golden

Dissertations and Theses

In the United States, smoking causes preventable diseases, including lung cancer, which is the leading cause of cancer deaths. Improving smoking cessation rates is important to decrease lung cancer deaths. Health care visits with a discussion about lung cancer screening (LCS) may help in increasing prevalence of smoking cessation. Importantly, insurers now require clinicians to have a shared decision-making discussion with patients that includes discussion of smoking abstinence before they can receive an LCS scan (i.e., a low-dose computed tomography scan). This discussion may represent a unique opportunity to encourage smoking cessation since it may prompt positive smoking behavior change. …

Aryne-Guided C-H Functionalization Of Benzenoid Rings Using Diaryliodonium Salts, Aleksandra Nilova

Dissertations and Theses

The benzenoid core is a frequent and irreplaceable component of biologically active molecules. Structure function relationship of these compounds has been broadly analyzed and presented in numerous literature reports. Herein, we augmented existing knowledge by a broad analysis of the benzenoid substitution patterns in small molecule active pharmaceutical ingredients approved by the FDA. Our findings reveal a strong correlation that the most represented substitution patterns are those achieved via S_EAr. Despite the rapid development of methods to functionalize benzenoid rings, the lack of synthetic methodologies to access sterically and electronically unfavorable positions is highlighted. We sought to establish …

Microplastics In Pacific Northwest Bivalves: Ecological Prevalence, Harvester-Consumer Exposure, And Aquarium Exhibit Outcomes, Britta Rahel Baechler

Dissertations and Theses

Up to 23 million metric tons of mismanaged plastics enter the global ocean annually. Microplastics (MPs;<5mm) degrading. MPs leak into the environment and now pervade every corner of the earth, with implications for animal, plant, ecosystem and human health. It is important to understand localized environmental MP prevalence, distribution and organismal uptake in order to determine the extent of MP pollution, and ultimately unlock solution sets to reduce transmission of MPs into the natural world. In Chapter 2, I quantified MP types, concentrations, anatomical burdens, geographic distribution, and temporal differences in Pacific oysters (Crassostrea gigas) and Pacific razor clams (Siliqua patula) from 15 coastal sites in Oregon. Both of these species are integral to culture, economy, gastronomy and food security along the United States West Coast. In Chapter 3, I quantified MPs in Pacific razor clams collected from 8 Olympic Coast, Washington sites, administered questionnaires to recreational razor clammers and subsequently estimated annual MP exposure of those Olympic Coast razor clam harvester-consumers surveyed. In Chapter 4, I designed and installed an educational ocean plastic …

Methodologies To Quantify Transit Performance Metrics At The System-Level Using High-Resolution Gps, Stop-Level, And Gtfs Archived Transit Data, Travis Bradley Glick

Dissertations and Theses

Performance metrics have typically focused at two main scales: a microscopic scale that focuses on specific locations, time-periods, and trips; and, a macroscopic scale that averages metrics over longer times, entire routes, and networks. When applied to entire transit systems, microscopic methodologies often have computational limitations while macroscopic methodologies ascribe artificial uniformity to non-uniform analysis areas. These limitations highlight the need for a middle approach.

This dissertation presents a mesoscopic analysis based around timepoint-segments, which are a novel application of an existing system for many transit agencies. For this research, routes are divided into a consecutive group of bus stops …

Use Of Carbon Fiber Reinforced Polymer (Cfrp) Including Sheets, Rods, And Ropes In Strengthening And Repairing Long Reinforced Concrete Columns, Yasir Matloob Saeed

Dissertations and Theses

The use of FRP materials in strengthening and repairing of reinforced concrete (RC) structures has increased in the past two decades. Recently, FRP materials have become one of the most used materials in rehabilitation engineering. For seismic retrofitting of RC structures, usually the process involves strengthening or repairing the vertical support elements of the buildings or bridges. Several studies focused on the use of FRP materials in strengthening and repairing RC columns. Externally bonded (EB) FRP sheets or laminates and near-surface-mounted (NSM) FRP rods have been used for enhancing the strength and ductility of RC columns. Although glass FRP (GFRP) …

A Posteriori Error Estimates For Maxwell's Equations Using Auxiliary Subspace Techniques, Ahmed El Sakori

Dissertations and Theses

The aim of our work is to construct provably efficient and reliable error estimates of discretization error for Nédélec (edge) element discretizations of Maxwell's equations on tetrahedral meshes. Our general approach for estimating the discretization error is to compute an approximate error function by solving an associated problem in an auxiliary space that is chosen so that:

-Efficiency and reliability results for the computed error estimates can be established under reasonable and verifiable assumptions.

-The linear system used to compute the approximate error function has condition number bounded independently of the discretization parameter.

In many applications, it is some functional …

The Impact Of Paternal Caregivers For Youth Who Commit Sexual Offenses, Miranda Hope Sitney

Dissertations and Theses

This dissertation presents three manuscripts exploring the impact of caregivers, particularly male caregivers, on the development of juvenile sexual offending behavior. The first manuscript investigated the role of disrupted caregiving for juvenile sexual offenders compared to non-offending juveniles and youth who committed non-sexual crimes. The results indicated that juvenile sexual offenders have particularly poor relationships with their primary caregivers, especially if their primary caregiver was male. The second manuscript is a systematic literature review that explored the pathways through which male caregivers may influence the sexually aggressive behavior of their sons. A total of thirty-four articles describing three pathways (i.e., …

Inclusion For Speech-Language Pathology Minority Graduate Students, Teresa Michelle Roberts

Dissertations and Theses

Speech-language pathologists provide assessment and intervention for communication, cognition, and swallowing disorders for individuals across the lifespan in educational, medical, and private practice settings. The demographics of professionals in the field do not reflect those of the general public in regard to race and ethnicity, gender, socioeconomic status, LGBTQ+, and disability. Lack of representation of minorities limits research, policy, and services designed to serve diverse populations. Although initiatives have sought to address lack of diversity of speech-language pathologists, limited research on the graduate training experience for minority students is available. Since a master's degree is required to become a speech-language …

Home Resources Supporting Workplace Resources: An Investigation Of Moderated Intervention Effects From The Study For Employment Retention Of Veterans (Serve), Sarah Nielsen Haverly

Dissertations and Theses

Social support directly impacts psychological outcomes both within the home and work domains. Hammer and colleagues suggest that social support at work from supervisors is related to a number of positive workplace outcomes. Kossek et al. elaborated that social support from supervisors is additionally effective when it is tailored to the unique needs of workers (i.e., role demands). The Veteran Supportive Supervisor Training (VSST) educates supervisors how to better support former service-members employed within the civilian workplace. Additional sources of social support are also key to positive outcomes for workers. Research shows that support from a partner or spouse can …

Investigation Of Prussian Blue Analogues As Cathode Materials For Next Generation Batteries, Neal Walters Kuperman

Dissertations and Theses

Since the beginning of the industrial revolution, the average global temperature has risen about 1 °C due increases in anthropogenic greenhouse gases emitted into the atmosphere. Of all human produced greenhouse gases, carbon dioxide is the most prevalent, with the production of electricity from fossil fuels being the major contributor.

Solar and wind power are promising net zero emission energy sources but only accounted for ~5% of global electricity generation in 2016. The most significant hurdle hindering their widespread adoption is the intermittent nature of the electricity generation. To overcome this limitation, significant resources need to be put into the …

History And Memory In The Intersectionality Of Heritage Sites And Cultural Centers In The Pacific Northwest And Hawai'i, Leah Marie Rosenkranz

Dissertations and Theses

While working to maintain contemporary and future relationships with stakeholders, heritage sites and cultural centers across the United States attempt to tell the history and experiences of the land and people who were once there, are there in the present, and will be there in the future. Fort Vancouver National Historic Site is one of these heritage places. This study is a response to current management needs identified for the Fort Vancouver National Historic Site. Through an internship with the ongoing Fort Vancouver National Historic Site Traditional Use Study, my research examines how heritage sites and cultural centers fulfill the …

Determinants Of Green Purchase Intentions Of Saudi Consumers, Amani Mohammed Kaadoor

Dissertations and Theses

Much of the research on how and why consumers engage in pro-environmental consumption has occurred in the wealthy countries of the West, where green markets are increasingly well established. Research in other economic and cultural context is sparse and points to large regional differences that cause some researchers to call key theoretical foundations, such as the Theory of Planned Behavior, into question. In response, this study investigates the factors that predict green purchase intention for food and personal care products in Saudi Arabia, a wealthy country with a rapidly growing population, severe environmental challenges, and a nascent green consumer market …

Exploring The Potential Of Sparse Coding For Machine Learning, Sheng Yang Lundquist

Dissertations and Theses

While deep learning has proven to be successful for various tasks in the field of computer vision, there are several limitations of deep-learning models when compared to human performance. Specifically, human vision is largely robust to noise and distortions, whereas deep learning performance tends to be brittle to modifications of test images, including being susceptible to adversarial examples. Additionally, deep-learning methods typically require very large collections of training examples for good performance on a task, whereas humans can learn to perform the same task with a much smaller number of training examples.

In this dissertation, I investigate whether the use …

Moonlit Nights And Seasons Of Romance: Yosano Akiko's Use Of The Moon In Tangled Hair, Teppei Fukuda

Dissertations and Theses

Ever since they opened their country to the world in the late nineteenth century, the Japanese experienced drastic changes in many aspects. They rapidly absorbed Western culture with their desperate hope to modernize their country in politics, the sciences, and art. Literature was not an exception. Yosano Akiko (1878-1942), who is well known as a pivotal poet of Japanese Romanticism, absorbed this new modern sense of self and individuality and advocated the poetic expression of one's private and personal emotions.

In premodern Japan, poets had traditionally expressed their feelings through a set, limited range of classical landscapes and natural objects, …

Implicit Learning Of Children With And Without Developmental Language Disorder Across Auditory And Visual Categories, Wanchi Yu

Dissertations and Theses

The current study examined implicit sound- and visual-meaning-mappings of children with and without Developmental Language Disorder (DLD).

One child with DLD and 29 children with typical language development (TLD) were included in the study, based on results from a hearing screening and standardized assessments of cognitive and expressive language skills. Participants completed two computer-based experiments, which were designed to investigate: 1) sound discrimination (pitch and duration), implicit mapping of sound stimuli to objects; 2) visual discrimination, implicit mapping of visual stimuli to objects.

The current study showed that children with TLD who implicitly learned pitch categories showed better mapping of …

Plasma Proteins That May Cause Parkinson’S Disease And Multiple Sclerosis: A Mendelian Randomization Study, Brigid A. Staley

Dissertations and Theses

Multiple sclerosis (MS) and Parkinson’s disease (PD) are progressively disabling neurologic disorders that profoundly affect quality of life and shorten life expectancy. There is no cure for either disease, and current treatments only alleviate symptoms and may cause serious side effects. The causes of MS and PD are not well understood. Previous epidemiologic studies have documented numerous environmental risk factors for both diseases. However, these studies are inherently prone to bias from confounding which may generate spurious results. The lack of unbiased evidence on environmental causes of MS and PD has been a critical barrier to fully understanding their pathophysiology. …

The Impact Of The Deficit Reduction Act Of 2005 On The Length Of Hospital Stay, Honamattie Dabydeen

Dissertations and Theses

ABSTRACT

Introduction

Hospital-acquired infections (HAIs) are the most common complications of hospital care in the United States, and at least 1 in 10 patients admitted to the hospital will develop one. These unnecessary complications lead to about 99,000 premature deaths per year and add approximately $35–$45 billion of direct costs. Most of the cost increase is due to increases in hospital length of stay (LOS). This study examines the effect of a federal policy change on LOS among people with an HAI using the Donabedian quality of health care model as a framework. Specifically, this study examines the effect of …

Do Fungal Symbionts Of Salt Marsh Plants Affect Interspecies Competition?, Vanessa Robertson-Rojas

Dissertations and Theses

The effects of arbuscular mycorrhizal fungi (AMF) as salt marsh plant symbionts may have significant effects on landscape scale distribution patterns and plant-related ecosystem functions that are important to estuarine habitats. This work investigates the effects AMF have on Phalaris arundinacea, Deschampsia cespitosa, and Juncus balticus when grown in a common garden experiment. Plants were grown with and without AMF inoculation in both polyculture and monoculture communities and examined for a variety of response variables that represent different competition strategies. Factorial ANOVA analysis revealed a significant three-way interaction among fungal treatment type, community type, and species for …

Approximate Pattern Matching Using Hierarchical Graph Construction And Sparse Distributed Representation, Aakanksha Mathuria

Dissertations and Theses

With recent developments in deep networks, there have been significant advances in visual object detection and recognition. However, some of these networks are still easily fooled/hacked and have shown "bag of features" kinds of failures. Some of this is due to the fact that even deep networks make only marginal use of the complex structure that exists in real-world images. Primate visual systems appear to capture the structure in images, but how?

In the research presented here, we are studying approaches for robust pattern matching using static, 2D Blocks World images based on graphical representations of the various components of …

Indoor Air Quality Impacts Of A Woodstove Exchange Program In Washington County, Oregon, Matthew Forrest Survilo

Dissertations and Theses

More than six million people in the United States use wood stoves as their primary heat source. Wood stoves emit air pollutants that may impact health, e.g., wood combustion products are associated with premature death and aggravation of pulmonary and cardiovascular conditions. There are few studies investigating the efficacy of wood stove exchange programs (WSEPs) as a method to improve indoor air quality (IAQ). In partnership with Washington County Department of Health and Human Services we conducted an air quality study to measure the impact of a WSEP on indoor and neighborhood levels of wood combustion products. Twenty households engaged …

Variation In Female And Male Dialogue In Buffy The Vampire Slayer: A Multi-Dimensional Analysis, Amber Morgan Sanchez

Dissertations and Theses

Media representations of gender often reflect normative societal beliefs about gender and have the ability to both reinforce and subvert those beliefs. The current study examines the linguistic characterization of male and female characters on the television show Buffy the Vampire Slayer, a series with an overt feminist message. Previous studies of gender variation in dramatic dialogue have found that female characters tend to be portrayed as using more linguistic features associated with an interpersonal and emotional focus (involvement), while male characters are portrayed as using more features centered on the transfer of information. Previous research has also found …

An Investigation Of The Temporal Relationship Between Agitation And Sleep Disturbances, Emily Catherine Denning

Dissertations and Theses

Suicide rates in the United States have increased almost 30% since 1999, making it the tenth leading cause of death in the country. This problem is especially prominent for veterans of the U.S. Armed Forces, as veterans comprise 8.5% of the U.S. population, yet they account for 18% of all deaths by suicide. These increasing rates have spurred the need for a better understanding of suicide risk, especially for this high-risk group. Previous research has focused mostly on chronic risk factors, which are useful for identifying who from a population may be more likely to engage in suicidal behaviors, but …

A Daily Examination Of Anger And Alcohol Use Among Post-9/11 Veterans, James David Lee

Dissertations and Theses

Anger problems have been commonly reported among military service-connected individuals. Current estimates of self-reported anger issues among post-9/11 veterans are around 57%. Alarmingly, it's been reported that anger does not decrease over the course of the post-deployment period; left unmanaged, it has been associated with a higher risk for suicide, post-traumatic stress, and hazardous alcohol use. Heavy drinking within military-connected samples has also been a well-documented phenomenon. Recent findings suggest that service-connected individuals may cope with adversity and regulate emotions through alcohol use, which may put them at risk for developing alcohol use disorders. While some evidence has observed a …

Nurse Can't Even: The Immediate Impact Of Incivility On Affect, Well-Being, And Behavior, Katharine Lucille Mcmahon

Dissertations and Theses

Interest in researching incivility has increased over the past two decades, as it is recognized as a pervasive issue in the workplace. Certain industries, such as healthcare, pose a higher risk for the aggressive encounters. Low intensity aggression, namely incivility, has a dangerous combination of high prevalence and invisibility that demands an understanding of the target's subsequent reaction process. Following rationale based on the Personality Systems Interaction (PSI) theory, this study proposes that the affective shift directly mediates the relationships between incivility exposure by coworkers and presumed behavioral and well-being outcomes at the day level in a daily diary design. …

This research fills a …

Transitioning Into Conventional Housing: Narratives Of Houseless Individuals, Joyce La Belle Mcnair

Dissertations and Theses

Past research has shown that it is possible for individuals to exit houselessness. However, it does little to provide insights into the types of experiences and events that facilitate these moves towards housing stability. This study explores indepth interviews, utilizing an interview guide with 12 individuals who exited houselessness in Portland, Oregon. This research project seeks to understand the conditions that influence successful exits out of houselessness from the perspective of the lived experiences of once houseless individuals. This study utilizes two theoretical frameworks, the theory of Habitus (Bourdieu, 1977 & Wacquant, 1998) and the networking theory of Strong and …

Engaging Communities In Archaeology On Private Property In An Urban Neighborhood: The Search For The First (1825-1829) Fort Vancouver, Vancouver, Washington, Amy Carolyn Clearman

Dissertations and Theses

Current archaeological literature calls for archaeology to become increasingly relevant in the modern world. Involvement in archaeological research can enhance the relevancy of archaeology for participants of public archaeology projects by strengthening personal connections with heritage and history. To investigate the impact of direct involvement in archaeological research on residents in Vancouver, Washington, I recruited members of two neighborhoods associated with Fort Vancouver National Historic Site to participate in the archaeological search for material remains of the first (1825-1829) Fort Vancouver. I asked the question: How does involvement in a public archaeology project affect participants' feelings about heritage, archaeology, and …

The Investor-State Dispute Settlement (Isds) Debate: Do Savings Provisions Influence Arbitration Outcomes?, Ryan Manning Moore

Dissertations and Theses

Investor-State Dispute Settlement (ISDS), an instrument of international trade and investment law, today leads perceptions regarding the integrity of international dispute resolution and its administration. If confidence in international economic institutions to render judgements which are impartial to political influences become suspect, then their durability will erode. This inquiry investigates whether or not power imbalances are reflected inordinately within ISDS arbitration outcomes between host nations and their foreign investors. Although there have been clear instances which question any observer's view of ISDS impartiality, these outcomes have also served to distort a complicated fabric of case results that have changed and …

Investigation Of Magnetism In Transition Metal Chalcogenide Thin Films, Michael Adventure Hopkins

Dissertations and Theses

Layered two dimensional films have been a topic of interest in the materials science community driven by the intriguing properties demonstrated in graphene. Tunable layer dependent electrical and magnetic properties have been shown in these materials and the ability to grow in the hexagonal phase provides opportunities to grow isostructural stacked heterostructures. In this investigation, cobalt selenide (CoSe) and nickel selenide (NiSe) were grown in the hexagonal phase, which consist of central metal atoms that are natively ferromagnetic in bulk, hence providing the potential for interesting magnetic phases in thin film arrangements as well. These structures may play a role …
