Assessment Of Vertical Accuracy From Uav-Lidar And Structure From Motion Point Clouds In Floodplain Terrain Mapping, Andrew Muller

Dissertations and Theses

Remote sensing technologies are being applied to a variety of uses because of the increase in access to various products (digital sensors, UAVs, software) and its ability to model relatively large areas in a short amount of time. While these new technologies are beginning to be adopted, validation of their merit in floodplain terrain mapping is lacking. The main goal of this study is to evaluate the vertical accuracy of digital elevation models (DEMs) generated with UAV-based LiDAR and Structure from Motion (SfM), also known as photographic LiDAR or PhoDAR. Airborne (manned aircraft) LiDAR has been applied to river research …

Nature-Based Solutions In Environmental Planning: Ecosystem-Based Adaptations, Green Infrastructures, And Ecosystem Services To Promote Diversity In Urban Landscapes, Lorena Alves Carvalho Nascimento

Dissertations and Theses

Nature-based solutions encompass strategies that explore ecosystem-based adaptations, green infrastructures, and ecosystem services in environmental planning and landscape management. However, nature-based solutions do not always consider ecological values and perspectives from Black, Indigenous, and Global South population. This dissertation has three independent papers that explore the application of ecosystem-based adaptations, green infrastructures, and ecosystem services in communities unheard by environmental planning agencies. The first paper is a conceptual framework that used literature review and observations of current human-nature interactions to reflect how the criminalization, acculturation, and cultural appropriation of cultural ecosystem services have burdened Black and Indigenous identities. Recommendations for …

An Examination Of Nurses' Schedule Characteristics, Recovery From Work, And Well-Being, Sarah Elizabeth Van Dyck

Dissertations and Theses

Recovery from work refers to the replenishment of energetic and affective resources depleted while meeting job demands, predominately conceptualized as a process that unfolds throughout the day. This study examined the shift work schedule demands presented by round-the-clock patient care needs on health care providers, and potential recovery opportunities during mid-shift meal and rest breaks. The cross-sectional data were collected via electronic questionnaire among registered nurses (N = 134) working in direct patient care roles in 24-hour healthcare organizations in the Northwestern United States (91.0% female-identified; mean age = 45.3 years). The main effects of adverse scheduling characteristics common …

Antipsychotic Medication Administration In Oregon Assisted Living/Residential Care Settings: Analyzing An Action Situation, Sarah Dys

Dissertations and Theses

Antipsychotic medication use (APU) in assisted living and residential care (AL/RC) settings is an under-studied and controversial health policy issue. APU in older adults with dementia is associated with an increased risk of falls, hospitalizations, and early mortality. I operationalize the Institutional Analysis and Development Framework using a situational analysis approach, an extension of grounded theory methods, to explore the APU in Oregon AL/RC settings. Regulatory deficiency citations, Oregon AL/RC population data, and semi-structured interviews suggest that staff role clarity, organizational characteristics, and perceived agency influence decision-making around APU. AL/RC providers and caregivers are forced to simultaneously balance and prioritize …

Sustaining Boys' Motivation Over The Transition To Middle School: Can Interpersonal Resources Protect Boys From Engagement Declines Across Sixth Grade?, Brandy Anne Brennan

Dissertations and Theses

Recent research has highlighted the challenges boys face in school. Boys are overrepresented on indicators of negative academic outcomes, such as detention, suspension, and dropout, as well as underperformance on state and national tests. Moreover, these effects may be long lasting: Compared to females, male students are less likely to graduate high school, enroll in college, and complete a college degree, and they may be particularly vulnerable in middle school. As students enter middle school, their motivation and engagement normatively decline, and these losses may be especially problematic for boys. Nevertheless, research documents the importance of close relationships with parents, …

Parenting And Children's Academic Coping As A Dynamic System: Feedforward, Feedback, And Mediators Of Changes Across The School Year, Kristen Elizabeth Raine

Dissertations and Theses

Using a motivational framework based in self-determination theory, the present study investigated the dynamic system between parenting and children's coping, defined as the ways they handle the everyday difficulties they encounter in school, using a sample of 1,020 students in grades three through six drawn from a larger cohort-sequential study. Three overarching research questions were examined using multiple regression that concerned 1) feedforward effects from parents' initial provision of motivational support (i.e., involvement, structure, and autonomy support) to changes in children's academic coping across the school year, 2) feedback effects from children's initial coping to changes in the same parenting …

The Role Of Emotional Attention Regulation In High Psychopathy Incarcerated Males, Michael K. Webb

Dissertations and Theses

This study examined the role of emotional attention regulation in men (N = 60) currently incarcerated in a Midwestern prison. Modern conceptualizations define psychopathy as a multifaceted and dimensional construct that includes atypical experience of affect, interpersonal problems, and remarkable social deviance. Attentional differences and deficient emotional experience have been shown to predict psychopathy and other outcomes related to the construct. However, attentional and emotional functioning in individuals high in psychopathy is complex and results have been shown to vary across discrete emotion states and experimental paradigms. The negative preception hypothesis (Kosson et al. 2018) suggests that these differences may …

Relation Of Emotion Regulation Difficulties, Self-Compassion, And Posttraumatic Stress Symptoms, Emily Anne Kalantar

Dissertations and Theses

Exposure to potentially traumatic events is associated with high emotion regulation difficulties, development of posttraumatic stress disorder, and elevated healthcare expenditures. Emotion regulation difficulties are related to worse clinical and sub-clinical posttraumatic stress symptomology relative to use of effective emotion regulation strategies. Yet, significant variance in posttraumatic stress symptom severity remains unexplained after accounting for emotion regulation difficulties, suggesting identification of additional explanatory variables is warranted. Considerable research suggests high (vs. low) self-compassion, which entails extending kindness to oneself, is related to more effective emotion regulation and low posttraumatic stress symptom severity. As such, self-compassion may be one variable that …

Is More Always Better? A Look At Visitation And Recidivism, Teriin Lee

Dissertations and Theses

The body of literature on prison visitation provides empirical support that visitation may influence the likelihood of recidivism. However, the literature is limited in both size and geographic representation, as more than half of studies originate from samples in Florida or Minnesota. Moreover, inconsistency in the use of measures further complicates generalizability of the findings. The following study utilizes data collected from the Oregon Criminal Justice Commission to examine the relationship between visitation and recidivism in Oregon. Using a sample of 29,312 adults in custody (AICs) who were released between 2011 and 2017, we test the associations of seven distinct …

Reducing Transphobic Attitudes: A Cross-National Investigation Of College Students In Japan And The United States, Kazusa Seko

Dissertations and Theses

Transgender people routinely experience discrimination and mistreatment. Although transphobic attitudes vary from country to country, a more in-depth understanding of these attitudes is needed. Using a semi-structured online survey, this study investigates college students' attitudes toward transgender people in Japan and the United States, a cross-national comparison that aims to deepen our understanding of how transphobic attitudes are shaped and what opportunities exist to reduce transphobia amongst college students. Results show that Japanese students express more transphobic attitudes than U.S. students do; and that U.S. students had more experience with gender-based educational content and were more likely to know someone …

Mothers' Drinking Motives, Sheila Kathleen Umemoto

Dissertations and Theses

Increases in women's excessive alcohol use are leading to concerns about a developing public health problem since, for women, it takes fewer years and lower doses to develop a range of alcohol-induced health problems. Maternal status is generally considered protective against alcohol use; however, this effect is weakened by multiple social role strain, leading to higher stress and negative affect, and subsequent coping-related alcohol use. Given that the majority of mothers with young children are working or looking for work (72.3%; BLS, 2021), it is likely that the combination of competing demands and expectations associated with multiple roles of parent, …

Mapping The Publics: The Production Of Spatial Knowledge And Public Interest, Paul Thomas Manson

Dissertations and Theses

Over the past decades, calls for comprehensively managing and planning ocean resources have emerged internationally and within the United States. Central to these calls is a drive to expand coastal and marine spatial planning with a particular focus on technologically mediated public involvement. These new public involvement technologies aim, more quickly and thoroughly, to solicit and analyze public values and existing uses of the coastal and marine environments. One particular technological innovation is the use of participatory geographic information systems (PGIS). These new tools allow for stakeholders, members of the public, and planning entities to collect, visualize, and interact with …

Modeling Environmental Factors Related To Drought-Induced Tree Mortality Based On Lidar And Hyperspectral Imagery, Lauren Nicole Sharwood

Dissertations and Theses

Climate change is projected to bring more frequent and prolonged droughts, causing widespread forest die-off. Identifying tree mortality over large spatial extents in response to the most recent California drought will help forest managers and conservationists understand where there may be a greater likelihood of future die-offs. In order to find more at-risk areas, this study evaluated how interacting site-specific topographic, climate, substrate, and stand characteristics mediated tree mortality in the Central Sierra Nevada during the 2012-2016 drought. The author used lidar and hyperspectral imagery provided by the National Ecological Observatory Network to identify individual dead trees using the Random …

Investigating Values In Discourse: Ideals And Social Plans, Luke Edward Hanst

Dissertations and Theses

Social scientists argue that values enable group coordination. I explore two theories of values before turning to evidence provided by Amanda Gorman's inaugural poem, "The Hill We Climb." First, the paradigm of Shalom Schwartz describes values as transsituational goals which enable groups to coordinate action and evaluate the world. I argue the Schwartz paradigm zooms out from values into categories while I need a means to zoom in to understand values in discourse. I turn to the Pragmatic Prospection paradigm to elaborate the cognitive ontology of goals and to understand the function of language. I argue that values are shared …

Japanese-English Code-Switching By Postwar Speakers In Contemporary America, Andre John Shepherd

Dissertations and Theses

In her examination of Japanese-English bilingualism in Toronto, Nishimura (1995b) demonstrated that second-generation Japanese-Canadians varied their speech dependent on the audience they were addressing. According to her, the Japanese-Canadians spoke primarily in English to fellow second-generation speakers, while maintaining conversations in Japanese with those who had spent their formative years in Japan. However, when addressing audiences composed of both groups, they switched back and forth evenly between the two languages.

Following research done by Woolard (1989) on the effects of societal influences on language, the state of the Japanese-Canadians can be related to the breakup of the ethnic enclaves in …

The Longitudinal Effects Of A Family And Sleep Supportive Intervention On Service Member Anger And Resilience, Shalene Joyce Allen

Dissertations and Theses

The vast majority of workplace intervention research on employee anger and resilience primarily focuses on individual-level strategies for mitigating employee anger and resilience outcomes in the workplace, with no studies having examined these outcomes with tangible occupational health interventions utilizing organizational-level techniques. Thus, the current study extends the literature on how to provide improvements in employee anger and resilience using higher system and organizational change mechanisms by providing evidence-based support for the effectiveness of a Total Worker Health® intervention, referred to as the Family and Sleep Supportive Intervention Training (FaSST). This approach employs both health protection and health promotion strategies …

The Discourse/Pragmatic Functions Of Japanese Okkē, Peter Fodor

Dissertations and Theses

Okay is one of the most commonly used words in the English language. It is also one of the most commonly borrowed English-origin loanwords across all of the world's languages. Although there is a wealth of research on the communicative functions of English okay, there is comparatively little research on the many borrowings of the word in various other languages. In order to address this gap in the literature, this study explores the differences in discourse/pragmatic function between the English word okay, and the Japanese borrowing of the word, okkē.

Extensive research in discourse analysis, pragmatics, and …

What Does It Mean To Be Deaf? Changing Meanings Of Deafness, Communication Technology, And Beliefs About Normality In The Us, Kathryn Elizabeth Burrows

Dissertations and Theses

How deafness is perceived as a problem by society dictates what types of technologies are leveraged to address the problem, and, conversely, available technologies shape how deafness is perceived. In this dissertation, I draw on multiple methods to explore the meanings of deafness in the US since the early 18^th century to the present, examine how the meanings of deafness in those eras shaped deaf technology, and assess how available technologies shaped how deafness was understood. Using primary and secondary historical sources, I identify that every era identifies a different "problem of being deaf" and it is that problem …

Guarding Against Strain: The Moderating Role Of Nonwork Experiences In The Relationship Between Work-Related Hypervigilance And Strain In Correctional Officers, Samantha Getzen

Dissertations and Theses

Correctional officers (COs) are expected to remain alert in order to maintain safety within the potentially hostile prison environment. As a result, COs experience high levels of work-related hypervigilance (WHV), which has been associated with negative health and wellbeing outcomes for COs. This study examines nonwork experiences as potential boundary conditions for the relationship between WHV and strain outcomes. It was hypothesized that nonwork experiences (psychological detachment, relaxation, mastery experiences, and exercise) would weaken the relationship between WHV and strain outcomes (emotional exhaustion, physical symptoms and impaired sleep). Data were analyzed from 166 COs in Oregon. A series of hierarchical …

Online Activism And Real Life Environmentalism, Emily Grace Anderson

Dissertations and Theses

Past and present human activities have created and accelerated an array of environmental catastrophes and various systems in the environment remain under threat as a result of human behavior. In hopes of mitigating environmental consequences, a social movement has arisen to encourage people to behave in ways that are more environmentally sustainable. Research shows that individual behavior choices impact the environment, and this influence can be used to positively affect the environment through engagement in pro-environmental behavior. Like with many other social movements, the internet has been a tool in spreading awareness of a cause and allowing people the opportunity …

Trump's Legacy In The Middle East: Strategic Shift And The Geopolitics Of American Foreign Policy In The Region, Bilel Kriaa

Dissertations and Theses

The last six months of the Trump administration witnessed interesting developments regarding its legacy in the Middle East. The normalization of ties between four Arab states and Israel constituted major breakthroughs not only in the regional inter-state relations but also for the American foreign policy in the region.

In this context, this thesis offers insights into how to understand and evaluate the administration's approach towards these developments. Based on systematic and empirical research, I analyze a corpus comprised of Trump-era foreign policy documents regarding the Iranian and Israeli-Palestinian questions. I find, firstly, that the Trump administration pursued a strategic shift …

Freedom Vs. Security: Analyzing The Connection Between States' Prioritization Of Security Over Civil Liberties And Citizen Support For Democratic Norms, Carlyn Trumbull Madden

Dissertations and Theses

Is global democracy declining? This is a question many have argued over, leading to multiple, oftentimes contradictory, answers regarding causes and potential solutions. This thesis seeks to explore the question of democratic decline by analyzing changes over time in public opinion survey data in three states- New Zealand, Turkey, and the United States- looking specifically at how the government has balanced the tradeoff between security and civil liberties in the post-9/11 world. I argue that long-term government prioritization of security over freedoms has eroded support for fundamental democratic norms, as citizens willingly accept restrictions to their rights in exchange for …

The Worth Of Risk: Political Participation And Risk Perceptions, Siri Grubb

Dissertations and Theses

This study draws on concepts from political and risk communication to inform our understanding of what motivates people to be politically active. Inspired by concerns that traditional models of participation do not perform as well among younger and more diverse populations, alternate variables are considered including risk perceptions surrounding policy issues and political parties. Results show that established political variables such as political interest and civic duty remain strongly associated with participation, while offering support for several new variables of interest from the risk communication literature. In the present study, threat and efficacy perceptions explained additional variance in political participation …

My Mountain, Your Mountain, Our Mountain: Incorporating Emotional And Sensory Experiences In Mapping Sense Of Place In Mount Hood National Forest, Alicia Ranae Milligan

Dissertations and Theses

Understanding the complex connections humans have with landscapes is necessary for successful land management and planning practices. Only within the last few decades has mapping the values of forest users been used to produce data that can be incorporated into forest planning as a means to better understand social and environmental dynamics. This research used sense of place web mapping coupled with interviews to understand forest users' emotional and sensory experiences within the Mount Hood National Forest and to improve future sense of place mapping research. Two objectives were addressed in this research: 1) develop a typology of individuals' emotions …

Forest Fire Effects On The Temporal Variability Of Landscape Snow Albedo Relative To Burn Severity, Max Gersh

Dissertations and Theses

Snow-water storage is decreasing, while forest fires are increasing in duration, size, frequency, and intensity, due to climate change. Most forest fires occur in the seasonal snow zone, altering snow mass and energy balance for many years following fire. Following forest fires, Surface snow albedo (SSA) decreases, as light absorbing particles (LAP), particularly black carbon (BC) produced in forest fires get deposited throughout the snowpack, altering snowpack energy balance driving earlier snowmelt in burned forests. While SSA decreases, landscape snow albedo (LSA) increases following fire, as more of the snow-covered surface becomes visible beneath the burned forest canopy, brightening the …

A Collaborative Approach To Cultural Resource Risk Assessment, Preservation, And Prioritization: A Case Study From Sauvie Island, Oregon, Phillip James Daily

Dissertations and Theses

New and increasing threats to cultural heritage resources have pushed archaeologists, land managers, and Indigenous peoples to develop strategies to identify at-risk resources, determine condition, vulnerabilities, and value of said resources, and then provide mitigation and preservation prioritizations and recommendations for the future. One such strategy is the risk assessment approach. Typically, to guide ongoing and future management of vulnerable cultural resources, risk assessments consider preexisting archaeological data, alongside geomorphological and hydrological landform characteristics, to prioritize sites for preservation. While such assessments have been conducted around the globe, they have not been widely applied on the Lower Columbia of Oregon …

Adoption And Use Of E-Grocery Shopping In The Context Of The Covid-19 Pandemic: Implications For Transport Systems And Beyond, Gabriella Abou-Zeid

Dissertations and Theses

In 2020, the COVID-19 pandemic drastically impacted travel for in-person shopping, commute trips, global supply chains, and food business operations. Previously mundane tasks, like shopping for food and household items, became markedly different as new social distancing and mask guidelines were put in place to mitigate the spread of COVID-19. Concurrently, e-commerce sales in the U.S. skyrocketed. E-grocery pickup and delivery services saw unprecedented expansions. The adoption and use of e-grocery services have implications for equity and mobility, although the nature of the relationship of e-grocery to the latter is still unclear. Enhancing our understanding of the drivers of (and …

"Like I Was An Actual Researcher": Participation And Identity Trajectories Of Underrepresented Minority And First-Generation Stem Students In Research Training Communities Of Practice, Jennifer Lynn Lindwall

Dissertations and Theses

Although calls for a more diverse workforce in biomedical fields have been widespread, racial and ethnic gaps in biomedical degree attainment remain. Contextualist perspectives seek to understand persistent STEM inequities by examining person-in-context experiences and how systemic factors filter into students' proximal contexts shaping their participation and science identity trajectories. Research training communities of practice aim to offer underrepresented minority and first-generation students support, guidance, and opportunities to learn the practices of science and construct their science identity. However, many students still choose to leave these programs. There is limited research on these students' science identity construction process and their …

Does Experiencing Spousal Support And Strain Impact The Quality Of Family-Based Support That Supervisors Provide To Employees?, Joseph Alvin Sherwood

Dissertations and Theses

Relying on previously collected data from the Work, Family and Health Study (WFHS), and drawing from a sample of 75 supervisors working in the extended healthcare industry, this research investigation empirically tested propositions of the Work-Home Resources Model to explore antecedents of family-supportive supervisor behaviors (FSSB). To explore these relationships a longitudinal, multi-level structural equation model (MSEM) was used to examine how supervisor contextual resources (spousal support) and demands (spousal strain) in the home domain impacted employee perceptions of these supervisors' FSSB through gains in personal resources (psychological distress) across three time points. Results from the MSEM model confirmed one …

'There Are No Bathrooms Available!': How Older Adults Experiencing Houselessness Manage Their Daily Activities, Ellis Jourdan Hews

Dissertations and Theses

Older adults living unhoused encounter limitations and challenges that drastically decrease their wellbeing and quality of life. The purpose of my study was to understand how experiencing houselessness impacted older adults' ability to conduct their activities of daily living (ADLs) and instrumental activities of daily living (IADLs) within their communities. I conducted phone interviews with older adults aged 50 and older who experienced houselessness in the Portland metro area. The participants described the persons and places that shaped their community life when they were living unhoused, and they described how those entities intervened to alleviate barriers to daily activities. The …
