Same Game, Different Rules: Pointillist Imperialism And The New Cartography Of Great Power Competition, Andrew Jesse Shaughnessy

Dissertations and Theses

For centuries, "Great Powers" competed for global hegemony not only through building up military strength and amassing wealth, but through the formal acquisition of distant lands, conquered and folded into their borders. Today, core states continue to vie for global power, but no longer exert formal control or sovereignty over less powerful states. So how has the nature of great power competition in peripheral states changed? Most scholars studying great power competition measure power in terms of military and economic resources, often failing to account for a third, crucial dimension in international power politics: the impact of distributed networks of …

Climate And Intraspecific Geographic Variation Of Nests And Eggs In The Eastern Kingbird Tyrannus Tyrannus, Samantha Marie Gillette

Dissertations and Theses

The reproductive success of birds is ultimately driven by the traits of nests, eggs, and incubation behavior and the interactions among them. Avian reproduction varies on large geographic scales, most prominently between tropic- vs. temperate-breeding species, but also on finer scales, such as along latitudinal and elevational geographic gradients. However, despite the importance of eggs and nests, how their traits vary geographically in response to differences in regional climate remains understudied.

We studied Eastern Kingbirds (Tyrannus tyrannus), which have been previously demonstrated to alter incubation length in response to local climate conditions. Our study sites, Kansas (KS), New …

The Daughters Of The Fronde: French Aristocratic Women And The Subversion Of Bourbon Absolutist Culture, 1661-1727, Jordan David Hallmark

Dissertations and Theses

The turbulent events of the Fronde des Princes (Fronde of the Princes), which saw the French nobility stage a failed rebellion against the monarchical administration of France's chief minister, Cardinal Mazarin, between 1650 and 1652, have been portrayed in the existing historiography as the swan song of a pre-absolutist nobility seeking to preserve its feudal identity as the king's partner in governance and military affairs. Indeed, as many historians of early modern France have observed, the policies pursued by Cardinal Mazarin following the monarchy's victory over the rebel princes of the Fronde, and subsequently expanded upon by Louis XIV after …

Transforming Learning Communities, Transforming Ourselves: A Qualitative Investigation Of Identity Processes In A Participatory Action Research-Themed Undergraduate Course, Julia Sara Dancis

Dissertations and Theses

In contrast to the dominant, post-positivist approaches to research in psychology, participatory action research (PAR) programs aim to democratize knowledge production and participate in social action through explicitly value-based and politicized agendas. Despite the inclusive nature of this work, college students are often left out of PAR collaborations and rarely even exposed to this frame of research. The handful of researcher-educators who have conducted participatory and action-oriented research with undergraduate students report a range of benefits for students, their universities, and the surrounding communities, confirming its importance. Left unaddressed are the key identity processes that unfold during knowledge production and …

A Walk In The Park: A Spatial Analysis Of Crime And Portland Parks, Cheyenne Pamela Hodgen

Dissertations and Theses

This thesis presents two individual research papers that examine the relationship between greenspaces and crime in Portland, Oregon. The two papers use an adapted street network buffer to better measure crime concentration around discrete locations. This methodological development allows for an improved measure of crime concentration around discrete locations.

The first contribution, explores the relationship between different greenspace types and crime, breaking down different crime types into discrete categories. The results of this study suggest that overall, Portland greenspaces do not experience a concentration of crime, however, different patterns emerge as greenspace and crime types are disaggregated. Only one greenspace …

"We've Created Cheap Energy Off The Backs Of Salmon": Dam Removal Politics And Alliances In The Lower Snake River Basin, Krista Harrington

Dissertations and Theses

Dams, once considered by many to be good for water development in the Western U.S., might not be a part of a climate resilient future. Dams have come under increasing scrutiny due to undesirable ecological implications. Although dam removal proposals are growingly popular in recent decades, they are controversial since they impact different stakeholders in different ways. In the Pacific Northwest, the Lower four Snake River dams have long been criticized for their negative impacts on salmon. In February 2021, US Congressman Mike Simpson (R-Idaho) proposed a comprehensive framework to deconstruct the Lower four Snake River dams as an attempt …

Mapping Ecosystem Service Flows Of Estuary Restoration Projects On The Oregon Coast To Identify Impacted Stakeholders, Shersten King Finley

Dissertations and Theses

The recent impetus for estuarine restoration has largely focused on resolving key ecological problems; however, less is known about how people might benefit or be impacted by restoration. By mapping benefits that flow from functional salt marshes and estuarine systems I examined how different social groups might be impacted by restoration based on race and class. In this study, I considered three ecosystem services (recreation, aesthetics, cultural/historical/spiritual) and where they might impact surrounding communities. In this paper I argue that stakeholder groups can be identified by mapping ecosystem service flow areas. I hypothesized that these three ecosystem services would have …

Assessment Of Spatial And Temporal Trends Of Exposure To Ambient Fine Particulate Matter And Ozone In New York/New Jersey Metropolitan Area, Subraham Singh

Dissertations and Theses

Background. Exposures to fine particulate matter (PM_2.5; particles with diameter less than 2.5 μm) and ozone (O₃) affect premature respiratory and cardiovascular mortality, morbidity and contribute to the development and progression of sub-clinical and clinical disease. Climate change affects air quality directly by modifying the thermodynamic properties of formation mechanisms and transport patterns, and indirectly, through increased emissions of PM_2.5 and O₃ precursors. The resultant changes in air quality influence human health outcomes through mechanisms of varying scale, timing, and complexity. PM_2.5 and O₃ levels have been declining due to the implementation …

Investigation Of The Association Of Exposures To Fire-Related Hazards With Pulmonary Function Of Firefighters, David G. Goldfarb

Dissertations and Theses

Background. Firefighters are habitually exposed to hazardous toxicants which place them at an elevated risk for numerous adverse health outcomes. An example of this is the associations observed in other works between inhalation of combustion byproducts from urban structural fires and both acute and chronic pulmonary dysfunction. To-date, the characterization of firefighters’ exposures to dangerous chemicals in smoke from non-wildfire incidents, both directly through personal monitoring and indirectly from work-related records is scarce. Prior works investigating the association between routine firefighting and pulmonary function have relied on crude metrics such as years of service and numbers of responses to …

Assessing Psychosocial Factors That Influence Water, Sanitation, And Hygiene Behavior In The Amhara Region Of Ethiopia, Kimberly Kamara

Dissertations and Theses

Background: The absence of potable drinking water from an improved source combined with inadequate sanitation and hygiene contributed to an estimated 1.9% of the global burden of disease in 2016. The estimated number of diarrheal deaths in 2016 was 1.4 million, of which 829,000 could have been prevented through improved drinking water and sanitation services, and hand-washing with soap. Despite the clear link between poor water and sanitation access and hygiene practices, 785 million people do not have access to water and two million do not have access to basic sanitation services. However, access does not automatically result in increased …

"I Just Had To Do Most Everything": Gender, Settlement And American Empire In The Far West, Hannah Alexandra Reynolds

Dissertations and Theses

The field of settler colonial studies has made huge strides in recent years toward problematizing the establishment of the United States on stolen land and the nation's steady, violent expansion across the continent. Settler colonial framework provides a rich opportunity for historians of the American West to reframe white settlement on the frontier, especially that which was made possible through land grant legislation such as the Homestead Act of 1862. As the families who took up land grant property sought new opportunities for themselves, they also acted as drivers of U.S. territorial acquisition. This process was inherently gendered, in terms …

Developing An Assessment Model For Entrepreneurship Ecosystems Using Hierarchical Decision Model: Case Study Of Riyadh City, Mustafa Kamal Almuzel

Dissertations and Theses

Entrepreneurship is one of the major drivers of economies. Countries that aim to improve their economies by increasing entrepreneurial activities and its effectiveness need to develop an effective entrepreneurship ecosystem. This ecosystem combines a set of domains and factors that create a healthy environment for entrepreneurs. The analysis shows that there is limited research about structured assessment methods to evaluate the entrepreneurship ecosystems.

Therefore, this research objective is to introduce a universal assessment model that can be adopted in different cities for implementing an effective entrepreneurial ecosystem. This will be achieved by addressing three main research questions. 1) What are …

Amplifying Arab American Heritage Language Students' Voices: A Multiple Case Study On Translanguaging Practices And Identity Negotiation In University Arabic Classrooms, Lina Gomaa

Dissertations and Theses

Little research has been conducted on Arab American students at universities and specifically, in the heritage language studies field. The experiences of Arab American heritage language (AAHL) students are significantly less examined than those of other heritage language students. Arabic language curricula and instructional practices in universities tend to privilege the teaching of Modern Standard Arabic over dialects, which marginalizes heritage learners' prior knowledge of the Arabic culture and its language, specifically Arabic dialects used in their home communities. These phenomena can create a non-affirming learning experience for these students. As such, in this study, I addressed these questions:

• To …

Le Gout Qui Reste: Cultural Identity And Belonging In Ook Chung's Kimchi, Taurean James Weber-Laurencio

Dissertations and Theses

The emphasis placed on the questioning of identity in Québécois society since the Quiet Revolution of the mid-twentieth century continues to this day. Whereas this search for a specifically Québécois identity was originally cast in terms of an Anglophone/Francophone divide, the influx of migrants from around the world to the province since the 1970s has rendered such a simplistic, binary discourse impossible. The population of Québéc in general and of Montréal in particular is now multicultural; visible minorities now constitute twenty-six percent of the Montréal populace. While most migrants in Québéc are able to find a niche in Montréal in …

Coming To Know The Local Environment: Children's Experiences In Rautamai Gaunpalika, Nepal, Elsie Nicole Love

Dissertations and Theses

This qualitative research, conducted over three months from late monsoon season into early fall of 2018 with twenty-six children and thirteen adults, explores how children in the hills of Rautamai Gaunpalika, Province 1, Nepal come to know their local environment. Semi-structured interviews with children, their family members, and teachers, and participant observation with children as they worked and played in forests, fields, and streams, suggest that outside of school, children come to know their local environment in the following ways: through participation in and application of knowledge to subsistence practices; through collaborative learning and teaching in mixed-age groups; through relationships …

Immigration Federalism In The United States: Constructing A Contemporary Institutional Framework Centered On Local Communities Through A Case Study Approach, Sara Kuehlhorn Friedman

Dissertations and Theses

This research study presents a new model of immigration federalism which integrates existing theories into a framework that emphasizes agency at the local level. Unlike dominant models of federalism that observe the cascading effect of higher-level policy on lower levels of government, this research focuses on empirical evidence at the local level to understand its relation to policy at higher levels. Immigration federalism is receiving substantial interest in scholarly work and in practice, but it lacks a cohesive and comprehensive theory explaining variation at the community level. There is little reason to expect sweeping changes in immigration policy at the …

Helminths Of Thomomys Species (Rodentia: Geomyidae) Of Oregon, Malorri Rene Hughes

Dissertations and Theses

Although often viewed as inconsequential, parasites have significant ecological and evolutionary importance, and studying them can generate knowledge regarding their environments and their hosts. Helminths (intestinal parasites) infecting Western pocket gophers (Thomomys species) in Oregon had been documented based only on morphology prior to this study. Basing parasite identification solely on morphology is problematic because the characteristics used to identify species can be vague or similar, leading to misidentification or obscuring the true biodiversity present. Using molecular markers to verify species present not only is more reliable but also can be informative in terms of the host-parasite association. To …

The Impact Of New Light Rail Service On Employment Growth In Portland, Oregon, Lahar Santra

Dissertations and Theses

This study quantitatively examines the impact of the new Light Rail Transit (LRT) service on employment growth in retail, knowledge, and service sectors before and after opening the LRT. At the corridor level, this study conducts a case study of Greenline in Southeast Portland, Oregon. The results of the corridor level study suggest that the new LRT service increased employment along the Greenline corridor among all the three sectors of interest- retail, knowledge, service in the long-term (ten years) while having slightly different results for the short-term (five years), likely due to the slow growth of LRT benefits. This study …

Spatial And Seasonal Variations Of Microplastic Concentrations In Portland's Freshwater Ecosystems, Rebecca Talbot

Dissertations and Theses

Microplastics are a pollutant of growing concern and are ubiquitous in a variety of environmental compartments. The majority of microplastics research to date has been conducted in marine waters, and less is known regarding the sources and delivery pathways of microplastics in urban rivers. The first chapter is comprised of a review of the scientific literature regarding the spatial and temporal factors affecting global freshwater microplastic distributions and abundances. Microplastic spatial distributions are heavily influenced by anthropogenic factors, with higher concentrations reported in regions characterized by urban land cover, high population density, and wastewater treatment plant effluent. Temporal variables of …

Heat, Wildfire And Energy Demand: An Examination Of Residential Buildings And Community Equity, Chrissi Argyro Antonopoulos

Dissertations and Theses

Extreme heat and wildfire events are becoming more prolific and exacerbated by climate change, carrying significant implications for environmental and social systems. Residential buildings play a central role in protecting people from heat and pollutant exposure during extreme weather events, but the level of protection varies dramatically depending on building energy efficiency and technology availability. Low-income and communities of color have higher energy burdens compared to affluent populations, and underserved communities often do not have financial resources for, or access to, advanced building technologies. This dissertation explores the impacts of extreme heat and wildfire on residential buildings, focused specifically on …

Geographies Of Urban Unsafety: Homeless Women, Mental Maps, And Isolation, Jan Radle Roberson

Dissertations and Theses

This study explores the intersection of urban unsafety and the marginalized population of homeless women. Specifically, it investigates how homeless women identify/perceive and navigate unsafe urban space. Specific research questions include:

1. What does housing insecurity look like for an unhoused woman?

2. In what ways is mental mapping a robust tool for gathering the stories (data) of vulnerable populations such as unhoused women?

3. What does the spatialization of unsafe locations look like and are demographic groupings dissimilarly affected?

4. What are the critical reasons for unsafety identified by participants?

5. How do homeless women respond to urban unsafety; …

Molecular Genetic Investigation Of Twins, Families, And Populations, Jeffrey John Beck

Dissertations and Theses

Twins have long been of interest for illuminating genetic and environmental influences on human traits and diseases. These explorations have been accelerated by the substantial amount of information collected from twins and their families participating in twin registers around the world. In this dissertation, I review what is known and what remains unknown about the biology and genetics of twins and the underlying twinning process. To elucidate additional genetic factors of the twinning process, I employed pedigree-based analysis to identify genetic regions shared among distantly related mothers of dizygotic twins. The shared regions may potentially contain rare genetic variants with …

Confined In (Patri)Architecture: How Gothic And Horror Literature Exposes Ongoing Violence And Oppression Against Women, Clara A. Macilravie Cañas

Dissertations and Theses

This project focuses on the intersections of space, power, gender, religion, and the architecture of institutions that confine and repress women. I argue that these texts focus on how patriarchal and domestic ideologies lock women into gendered expectations through oppressive gender politics. Chapter one demonstrates how early gothic female writers used representations of physical structures, such as abbeys and castles, to expose the eighteenth-century woman’s experiences of abuse and confinement by repressive patriarchal and monarchal rule. This chapter connects themes and arguments within Sophia Lee’s The Recess (1783) and Ann Radcliffe’s A Sicilian Romance (1790) to reveal the metaphors that …

A Temporal Examination Of The Connections Between Convective Available Potential Energy And Convective System Development, Chad A. Small

Dissertations and Theses

In 1983, the World Climate Research Programme launched its first project: the International Satellite Cloud Climatology Project (ISCCP). While the ISCCP has succeeded in many of its cataloging and analytical goals, one of its flagship products, the Convection Tracking (CT) Database does not contain certain environmental parameters that are essential in understanding how, and when, convection is initiated or intensified. The development of mesoscale convection – notably, convective systems (CS) – is also largely dependent on parameters like convective available potential energy (CAPE) which the ISCCP CT Database does not record. By tying information on CAPE to CS, discoveries in …

Analysis Of The Influence Of Cryptocurrency Regulation On Levels Of Financial Literacy, Kieran C. Yuen

Dissertations and Theses

Using data collected by the National Financial Capability Study (NFCS), a survey by the Financial Industry Regulatory Authority (FINRA), this paper investigates the influence of passage of cryptocurrency regulation in U.S. states on levels of financial literacy. Results indicate that living in a state where cryptocurrency regulation was signed into law, a decrease was observed in the level of financial literacy. This finding supports the growing literature on factors that affect levels of financial literacy using a novel exogenous variable, cryptocurrency regulation.

Population Structure Of The Lizard Ecpleopus Gaudichaudii Coincides With A Biogeographic Barrier - The Doce River, Alexander J. Garretson

Dissertations and Theses

Intraspecific genetic variation is an integral component of diversification and the accumulation of biodiversity. The degree to which isolated populations of the same species are genetically structured in geographical space is impacted by a variety of mechanisms. In this study, I document patterns and discuss possible drivers of genetic structure within Ecpleopus gaudichaudii, a lizard species endemic to the Atlantic Forest of Brazil. For that, I assembled ddRadseq sequences from 48 individuals across much of the range of the E. gaudichaudii and analyzed its population structure. I created an intraspecific phylogeny for this group utilizing RAxML and conducted a …

The Gendered Interpretation Of Child Marriage: A Niger Case Study, Melissa Safi

Dissertations and Theses

This paper seeks to answer the question, what is the primary factor driving child marriage? I explore the literature in several scholarly articles that explain why the harmful, traditional practice of child marriage is an issue that predominantly affects girls globally. I also utilize the feminist theory of international relations to support my analysis of child marriage as a gender issue. Incorporating evidence from annual international reports, scholarly articles, and mixed methods studies, this paper examines a case study of Niger, where child marriage affects more than half the population of girls under the age of 18. In studying Niger, …

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 …

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 …
