Assessing Airborne Radar To Map Glacier Elevations In Alpine Terrain Including Estimated Glacier Volume Change, Bryce Allen Glenn

Dissertations and Theses

Alpine glaciers and perennial snowfields (G&PS) are important hydrologically and ecologically, providing meltwater during the hottest and driest summer periods. Climate warming shrinks these natural reservoirs while temporarily providing increased streamflow. To assess regional changes in glacier volume, from which contribution to streamflow can be estimated, I used NASA's Airborne Glacier and Ice Surface Topography Interferometer (GLISTIN). This instrument mapped the surface topography of alpine glaciers; differencing these elevations from historic elevations derived from topographic maps, volume change is calculated. GLISTIN was flown over the glacier-populated mountain ranges of the western U.S. Of the 3289 glaciers and perennial snowfields with …

A Historical Ecology Of Aridland Springs In Desert National Wildlife Refuge, Nuwu/Nuwuvi (Southern Paiute/Chemehuevi) Ancestral Territory, Nevada, Yarrow Sarah Valentine Geggus

Dissertations and Theses

Aridland springs are among the most threatened ecosystems in the world. Vital to desert ecologies and Indigenous cultures, these complex and individualistic ecosystems have layered histories. To inform management in the changing landscape of Desert National Wildlife Refuge, a 1.6 million acre protected area in Southern Nevada, I conducted a historical ecology study of a sample of ten upland springs. Through a six-part interdisciplinary methodology including interviews, archaeological survey, botanical survey, and archival research, I summarize findings into three broad eras: the Nuwu/Nuwuvi pre-Contact Era, the Settler Era, and the U.S. Fish and Wildlife Service Era.

For millennia, Nuwu/Nuwuvi drank …

Examining Bicycle And Motorized Vehicle Speeds And Their Relationships In The Context Of Urban Roadways, Jaclyn Sue Schaefer

Dissertations and Theses

This thesis presents a compilation of papers exploring passenger car and bicycle speeds through their interactions with each other and with urban roadway factors.

First, following a concern raised in part of the traffic literature that a large mode shift toward bicycling may cause travel time delays and potentially exacerbate congestion instead of alleviate it unless bicycle lanes are installed, an empirical study detailing how the presence of bicycles on urban roads without bicycle lanes may affect passenger car speeds is presented. Pneumatic tube data from six predominantly low speed, low volume roads in Portland, Oregon were utilized to identify …

The Electronic Hardware Music Subculture In Portland, Oregon, James Andrew Hickey

Dissertations and Theses

Music is relatively understudied as a geographic phenomenon, but recently there has been a shift in academic literature to understand the social, cultural and economic factors that determine music and its development in specific places. The purpose of this study is to examine the Electronic Hardware Music Subculture (EHMS) in Portland, why it thrives, and how it is linked to the local cultural economy. To do this, I used semi-structured, long form interviews with key members of the EHMS. These interviews, and my own observations, gave insight into what factors affect the success of members of the EHMS, and how …

Human Energy In The Workplace: An Investigation Of Daily Energy Management Strategies, Job Stressors And Employee Outcomes, Morgan Rose Taylor

Dissertations and Theses

Recent research has pointed to the benefits associated with the use of work-related energy management strategies for employee outcomes. Using the Conservation of Resources Theory and the Challenge and Hindrance Stressor Framework, the current study extends the energy management literature by examining day-level relationships between work-related energy management strategies (e.g., organizing, meaning-making, and prosocial strategies) and employee outcomes, namely, goal progress, work engagement, and relational energy respectively. Further, challenge and hindrance stressors are tested as day-level moderators of these relationships. Using experience sampling methods across 10 workdays, results showed that day-level organizing strategy use was related to higher goal progress …

Aligning Food Environments With Institutional Values: A Mixed Methods Study Of Oregon Health Care Organizations, Elizaveta Walker

Dissertations and Theses

A major driver of the obesity epidemic is obesogenic food environments, characterized by nutrient-poor and energy-dense foods that saturate the collective physical, economic and sociocultural conditions that influence nutritional status. Food environments in organizations such as hospitals and public health agencies warrant special consideration given their health-focused mission. Improving food environments within health care settings has been highlighted by the Centers for Disease Control and Prevention (CDC) as one of seven key strategies to prevent obesity. However, most of the refereed literature examining healthy food environment policies (HFEPs) within hospitals focuses on the inpatient dietary environment, leaving a paucity of …

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 …

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 …

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. …

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., …

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 …

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 …

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. …

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 …

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 …

Waste Management In The Global South: An Inquiry On The Patterns Of Plastic And Waste Material Flows In Colombo, Sri Lanka, Katie Ann Conlon

Plastic waste connects to all social processes, especially within the context of urbanization and development; urban planning and land management; GHG emissions; labor; social equity; public health; rural-to-urban migration; increasing population; increasing consumption; climate change; etc. The focus of this dissertation is an analysis of waste management practices in Sri Lanka using a grounded theory based methodology, with a goal to better understand the social and ecological impacts of plastic waste in Sri Lanka. This research fills a …

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 …

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 …

Social Media Use, Social Comparison, And Loneliness, Jordan Elena Johnson

Dissertations and Theses

Since its invention, the use of Instagram and its psychological effect on users has been a topic of conversation for researchers. To achieve a better understanding of Instagram's effect on loneliness, it's important to isolate different behaviors on Instagram because of its different attributes as a social media app. Drawing on literature on the emotional effects of social media use and social comparison orientation (SCO), this study takes a closer look at specific Instagram behaviors: broadcasting, interacting, and browsing as well as SCO's relationship with loneliness. A total of 147 undergraduate students attending a university in the Pacific Northwest completed …

Outsiders Within Inequality Regimes: A Sociological Framework To Advance The Lives Of Women Veterans, Sarah Louise Aktepy

Dissertations and Theses

This three-paper dissertation examines pervasive gender inequalities across two institutions: the US military and Department of Veterans Affairs (VA). The first paper, "'Don't Rock the Boat:' Experiences and Perceptions of Gender-Based Violence in the U.S. Military" uses qualitative interviews to better understand the experiences of gendered harassment and violence of women veterans in the US military. The second paper, "First Do No Harm: Assessing Veterans Affairs Screening for Military Sexual Abuse among our Nations Veterans" uses survey data and qualitative interviews to identify factors that contribute to inaccurate results of clinical screening for veterans with military sexual violence histories within …

Comparing The Promise And Reality Of E-Scooters: A Critical Assessment Of Equity Improvements And Mode-Shift, Michael Glenn Mcqueen

Dissertations and Theses

In just three years, e-scooters have substantially disrupted and altered the urban mobility landscape. Throughout this period, they have been commonly touted as part of a larger micromobility solution that promises to erase equity barriers and solve the first-mile/last-mile problem. However, few studies in the nascent e-scooter literature have considered these claims. In this study, we surveyed students at Portland State University (n = 1,968) about the role that e-scooters, among other modes, played in meeting their general and university-related travel needs. We then estimated models that incorporated demographics, travel behavior, and latent attitudes distilled using exploratory factor analysis (EFA). …

Understanding Evangelical Support For, And Opposition To Donald Trump In The 2016 Presidential Election, Joseph Thomas Zichterman

Dissertations and Theses

This thesis addressed the conundrum that 81 percent of evangelicals supported Donald Trump in the 2016 presidential election, despite the fact that his character and comportment commonly did not exemplify the values and ideals that they professed. This was particularly perplexing to many outside (and within) evangelical circles, because as leaders of America's "Moral Majority" for almost four decades, prior to Trump's campaign, evangelicals had insisted that only candidates who set a high standard for personal integrity and civic decency, were qualified to serve as president.

In order to deal with this problem, I conducted a qualitative study, which followed …

An Examination Of Hiv Risk, Testing And Prevention Intervention Participation Among Vulnerable Youth, Bianca V. Lopez

Dissertations and Theses

Background: Young gay, bisexual and other men who have sex with men (YGBM) of color are disproportionately affected by HIV and bear the burden of the disease in the United States. Gay and bisexual men – referred to in surveillance systems as men who have sex with men (MSM) – continue to be the risk group most severely affected by HIV in the United States. The dissertation study explored factors related on HIV prevention intervention participation, HIV testing and sexual risk behaviors among YGBM ages 13-29 in the Bronx. Additionally, this dissertation endeavored to study the concept of “intervention fatigue”, …

Trailblazing Transformation: Pioneering Transformative Peacebuilding In Academic Labor Conflicts, Sam Frazier Hediger

Dissertations and Theses

Unionized contingent faculty in the United States face an increasingly difficult economic landscape in their labor-management conflicts with university administrations. These unions, comprised of graduate student employees and adjunct instructors, won significant victories for their members but have failed to shift the broader patterns of casualization, unsustainable compensation, and job precarity, stemming from the systemic debasement of higher education institutions and the American labor movement, both of which pose significant challenges to conventional conflict resolution strategies. To find a path forward, this thesis explores the nature and possibility of transforming of the academic labor conflict, using a transformative peacebuilding approach …

Impact Of 2012 Spanish Health Care Reform On Hiv-Positive Immigrants: A Mixed Methods Approach, Megi Gogishvili

Dissertations and Theses

Background: The financial crisis of 2008 hit Spain hard. As a consequence, the government took multiple austerity measures, including reforms in the healthcare system in 2012. Specifically, the government reduced the budget for health and social services by 13.7% in 2012.The reduction was further followed with structural changes via the 2012 Royal Decree Law (RDL) and Royal Decree (RD).The 2012 RDL and RD entailed broad areas of action,but most importantly the Spanish National Health System (SNS) no longer covered undocumented immigrants. The 2012 RDL and RD excluded approximately 500,000 undocumented immigrants from SNS.

The number of immigrants in Spain has …

Archaeologists, The Public, And Collectors: Establishing A Regional Database Of Archaeological Sites On Private Land And Collections With A Process For Professional-Public Archaeological Research In The Portland, Oregon Area, Katherine Louise Tipton

Dissertations and Theses

Over the course of daily life, people engage with archaeology in various ways, including experiences with archaeology on their own land and as part of family collections of archaeological material. As a result, members of the public often hold considerable archaeological knowledge that professionals have historically overlooked. Recent scholarship focuses on the issue of incorporating the public and collectors into archaeological research and ways for capturing that information. Professional-public collaboration is particularly important in the Portland, Oregon area, where many archaeological sites are located on private land and there is a long history of collecting.

The goal of this thesis …

Catholic Social Teaching And Sustainable Development: What The Church Provides For Specialists, Anthony Philip Stine

Dissertations and Theses

The principles of Catholic Social Teaching as represented by the writings of 150 years of popes as well as the theorists inspired by those writings are examined, as well as the two principal schools of thought in the sustainability literature as represented by what is classically called the anthropocentric or managerial approach to sustainability as well as the biocentric school of thought.

This study extends previous research by analyzing what the Catholic Church has said over the course of centuries on issues related to society, economics, and the environment, as embodied in the core concepts of subsidiarity, solidarity, stewardship, the …
