The Impetus Of International Security In European Integration: The Nature Of Eu Common Security And Defense Policy, Osman Goktug Tanrikulu

Dissertations and Theses

This study explores the complicated relationship between security considerations and the European integration process. The research uncovers specific security factors that have shaped the EU integration process. Applying policy alignment and collective efforts for governance, this study offers a methodological improvement to the conventional status quo satisfaction concept within power transition theory.

Findings indicate that external militarized actions targeting European nations only occasionally disrupted integration in the short term. Instead, inner coordination among member states vis-à-vis external actors, promoted integration. During the early stages of integration, alignment with the EU collective was crucial, while aligning with regional leader Germany became …

Branches In The Pipeline: Status-Seeking In Principal Licensure Candidates, Madhu Narayanan

Northwest Journal of Teacher Education

This paper investigates the reasons and motivations that people pursue administrative licenses. Questions such as who enrolls, why they choose to seek an administrative license, and what are their future goals, are all relevant to address challenges of principal attrition and turnover. With calls for the development of quality, equity-focused leaders, it is important to understand how motivations of entrants align with those of school districts and policy makers. This paper contributes to the research on the so-called “principal pipeline” by analyzing the reflections of candidates from an institutional perspective. This view considers modern schools to be social structures governed …

This qualitative study surveyed in-service teachers applying for their TESOL or Bilingual endorsements in a college in the southwest United States. Research questions asked about the challenges and successes teachers face in meeting the needs of multilingual students and used this data to determine themes. The data showed that teachers encounter challenges meeting the needs of multilingual students in the …

An Equity Framework To Engage Community College Preservice Teachers In Black Liberatory Practices, Denise Farrelly, Joanna Maulbeck, Laura Scheiber

Northwest Journal of Teacher Education

While representation of teachers of color remains startlingly low nationwide, it is critical to recognize that increasing diversity is not enough to increase access to an inequitable system. Centering the strengths of Black students, on both an individual and institutional level, through culturally and historically-responsive pedagogical and curricular practices is a crucial step toward equitizing the teaching workforce. Using a culturally and historically-responsive literacy (HRL) framework, we discuss and reflect upon practical classroom-based approaches to engage community college preservice teachers in responsive pedagogical practices that are aligned with the legacy of Black literary societies. The paper is divided into four …

The House Full Of Otters: Recalling Human–Sea Otter Relationships On An Indigenous Oregon Coast, Douglas Deur, Peter Hatch, Hannah Wellman

Anthropology Faculty Publications and Presentations

Sea otters have held a special role in the cultural, spiritual, and economic life of Native American communities throughout recorded time. Along the coast of what is now Oregon, Native oral traditions recall a rich history of human encounters with sea otters, and speak of the species’ ubiquity, significance, and sentience. Native people also hunted sea otters, fashioning their uniquely dense fur into chiefly robes and using the pelts in ways central to community life — presaging the species’ later role in the global fur trade. Archaeological evidence of sea otter use can be found in sites of diverse antiquity …

OHSU-PSU School of Public Health Faculty Publications and Presentations

Objective We describe awareness about the modified “public charge” rule among Oregon’s Mexican-origin Latino/a population and whether concerns about the rule influenced disenrollment from state-funded programs, which do not fall under the public charge. Methods We conducted a cross-sectional survey of adults (ages 18–59) recruited at the Mexican consulate and living in the state of Oregon. Our outcomes were awareness (of the public charge, source of knowledge, and confidence in knowledge of the public charge) and disenrolling self or family members from state-funded public healthcare programs due to concerns about the rule. We described outcomes and used logistic regression and …

Effective Entity Augmentation By Querying External Data Sources, Christopher Buss, Jasmin Mousavi, Mikhail Tokarev, Arash Termehchy, David Maier, Stefan Lee

Computer Science Faculty Publications and Presentations

Users often want to augment and enrich entities in their datasets with relevant information from external data sources. As many external sources are accessible only via keyword-search interfaces, a user usually has to manually formulate a keyword query that extract relevant information for each entity. This approach is challenging as many data sources contain numerous tuples, only a small fraction of which may contain entity-relevant information. Furthermore, different datasets may represent the same information in distinct forms and under different terms (e.g., different data source may use different names to refer to the same person). In such cases, it is …

Forest Fire Effects On Snow Storage And Melt Across Scales Of Forest Recovery In The Western Oregon Cascades, Megan Nicole Guinn

Dissertations and Theses

Snow is the largest component of water storage in the western United States, it serves as a key moisture source for forested ecosystems and is fundamentally linked to streamflow and nutrient cycling. Snow is vulnerable to climatic warming, and a key consequence of declining mountain snowpack is the escalation in wildfire frequency, extent, intensity, and duration across the seasonal snow zone. Fire modifies the spatial extent of snow in watersheds, reducing snow water storage and timing of melt across burned forests. Forested mountain ecosystems and water supplies are facing shifts in their structure, function, and succession. Previous research has focused …

Design And Characterization Of 2.4ghz Antennas For Wireless Sensor Applications, Luis Zogby Brennan

Dissertations and Theses

Wireless sensor networks benefit greatly from advances in circuit integration and miniaturization. However, antennas are bound to specific geometries both in terms of fundamental limits and their response to immediate surroundings. As such, various successful techniques for antenna miniaturization must still be carefully tested and characterized as part of the design process of a sensor system. The work presented here fully characterizes a number of miniaturized 2.4GHz antennas and successfully integrates designs into a sensor system using the highly integrated Single Chip Micro Mote (SCµM), which uses a crystal-less radio design resulting in the requirement of only a …

Modeling Leaf-Level Transpiration: Exploring The Consequences Of Assumed Saturated Vapor Pressure In Leaves, Danlyn L. Brennan

Dissertations and Theses

Understanding the dynamics of water transport through leaf intercellular airspaces (IAS) and its impact on transpiration is crucial for accurate predictions of plant water use and ecosystem response to changing climates. This study investigates the implications of assuming undersaturation of water vapor in the IAS for transpiration predictions and explores potential modifications to standard modeling approaches.

A dynamic 1D soil-plant-atmosphere continuum using a stomatal optimization model (SPAC-SOT) framework was used to simulate the response of tree species, P. edulis, to prolonged drought and varying environmental conditions. Comparisons between two model assumptions (saturated vs. undersaturated IAS) reveal notable differences in …

Disappeared Streams And Flood Risk In Atlanta, Georgia, Baltimore, Maryland, Phoenix, Arizona, And Portland, Oregon, Gregory Chrisopher Post

Dissertations and Theses

Many urban streams have been moved, culverted, buried, or "disappeared" as urban infrastructure was constructed. This loss of natural streams provided land for urban development, but as climate change increases the frequency and severity of extreme weather events, these disappeared stream areas could threaten homes and other infrastructure with increased flood risk. This study developed spatial data layers to identify many of these lost streams for Atlanta, Georgia, Baltimore, Maryland, and Phoenix Arizona, using historical maps to find streams previously visible that disappeared by the present day. This process used the oldest available georeferenced maps from the United States Geological …

Left Out To Dry: Understanding The Social Experiences Of Ground Depletion In Washington State's Columbia River Basin, Alexis Lisandro Guizar-Diaz

Dissertations and Theses

Millions of water wells worldwide risk running dry due to overpumping, drought, and climate change. This study adopts a political ecology framework to investigate how economic structures and power dynamics shape the effects of groundwater depletion in a highly impacted region. It is based on qualitative fieldwork conducted in the Odessa Aquifer region of Washington State. This agriculturally productive region has experienced severe groundwater depletion, endangering communities and threatening water supplies for many, as agribusiness has intensively used deep water wells to irrigate high-value crops. This research addresses three key questions: 1) How do residents and households excluded from irrigation …

Leed Buildings And Green Gentrification: Portland As A Case Study, Jordan Macintosh

Dissertations and Theses

LEED certification has become highly popular in the United State under the current political climate of addressing climate change, however in the implementation of green initiatives like LEED, social and economic impacts are not being considered. "Green gentrification" through the implementation of green initiatives such as LEED can cause displacement to highly vulnerable groups of people, disproportionately dealing the environmental goods to the wealthy and the environmental bads to the low income groups.

Portland has a fairly large amount of LEED buildings, and the city and state emphasizes its goals for sustainability through the use of green initiatives such as …

The planning concept of a "complete neighborhood" is defined as a locality that offers residents access to all essential aspects of daily life within a convenient walking distance. This notion encompasses elements, such as walkability, accessibility to essential services and amenities, sustainability, and equity. The objective of this study is to provide a more precise definition of the planning concept of a complete neighborhood and …

Stress-Reduction From Positive Support: Impacts Of Receiving Partner Capitalization Support On Veteran Stress/Work Stress, Maryann Dona Samson

Dissertations and Theses

Prolonged stress, a pervasive experience in the United States, has been linked to numerous adverse outcomes. The workplace commonly operates as a source of chronic stressors, in fact 25% of Americans find their job is the most stressful part of life. This tendency is particularly true for military veterans, who reliably experience elevated stress and burnout and low job satisfaction. Inspired by the pervasiveness and seriousness of the chronic stress issue, the current study addresses chronic stress in a veteran sample by examining the stress-protecting effects of social support. Whereas social support has traditionally been conceptualized as providing aid when …

Comparative Skull Morphology Of California Sea Lions (Zalophus Californianus) And Steller Sea Lions (Eumetopias Jubatus) In The Pacific Northwest And Implications For Hybridization, Ada Iris Garcia Garcia

Dissertations and Theses

Eumetopias jubatus (Steller sea lions) that breed on the Oregon coast are smaller than those found both in Alaska and California. During the breeding season, male Zalophus californianus (California sea lions) move past E. jubatus rookeries in Oregon on their way to their breeding rookeries in Southern California. Introgression potentially could explain the difference in size of Oregon E. jubatus relative to remaining populations. At Portland State University (PSU), the marine mammal collection of the Museum of Vertebrate Biology has over 200 skulls of Z. californianus and E. jubatus from throughout northern Oregon and southern Washington. To assess whether morphologically …

Left On "Read" And All Alone: Instigated Cyber Incivility, Shame, And Experienced Ostracism At Work, Alison Lucia Hunt

Dissertations and Theses

The mistreatment literature focused on workplace incivility has grown significantly over the past two decades, as it has been recognized as an omnipresent issue in the workplace. Workplace incivility presents itself as low-intensity rudeness in which at least one individual takes counter normative negative actions against another individual, and may take place in both office and remote work settings as well as through a cyber modality. These actions often occur in a spiral where the target of incivility becomes likely to perpetuate incivility later down the line. However, much of the incivility literature lacks a comprehensive understanding of the perpetrator's …

Mitigating Sex Trafficking: Preventative Methods For Reducing Sexual Exploitation, Autumn Rain Monroe

University Honors Theses

In recent years, sex trafficking has become more well-known in the public sphere, generating activism and legislation in an effort to combat this human rights issue. With this increased awareness comes challenges in appropriately understanding sex trafficking. The general public and even lawmakers often do not understand the complete dynamic or complexities of sex trafficking. Definitional inconsistencies make it difficult to provide a universal definition of sex trafficking, contributing to misconceptions involving the methods of entry and the barriers to exiting. Ultimately, this prevents proper identification of victims, hinders the protection of victims, and the implementation of survivor-oriented legislation, meaning …

Not On The Menu: Customer Sexual Harassment In The Restaurant Industry, Fernanda Wolburg Martinez

Dissertations and Theses

Despite the high prevalence of customer sexual harassment (CSH) paired with a high turnover in the restaurant industry, there have been few suggestions on resources that may attenuate the effect that bystander and direct CSH might have on strain--anxiety and depressive symptoms--and turnover intentions among restaurant workers. Based on the stipulations of the job-demands resources theory and the empowerment framework, the current study frames direct and bystander CSH as job demands that may be linked to employee strain and turnover intentions. Moreover, CSH preventive supervisor behaviors and organizational intolerance towards CSH are introduced as job resources that may weaken the …

Community Adaptations To Wildfire Risk In Central Oregon, Usa: An Empirical Study Of Inclusionary Practices In Collaborative Wildfire Risk Mitigation, Liam Resener

Dissertations and Theses

Adverse impacts of wildfire in Western North America have become increasingly present through the 21^st century, driven by landscape changes imposed by colonists in the 19^th and 20^th centuries. Community adaptations to wildfire will be necessary through the 21^st century to restore landscapes and protect the safety and livelihoods of people who live in at-risk areas. Wildfire risk extends across countless environmental and social systems, and individuals have competing ideas about what constitutes that risk and how to best adapt to it. As resources are being allocated to community adaptations, important questions emerge about the values …

The Influence Of Polystyrene Microplastics On Juvenile Steelhead Trout (Oncorhynchus Mykiss), Kaitlyn Marie Baker

Dissertations and Theses

Mass production of plastic within the past decade has led to over 100 billion tons of plastics being added to the world’s oceans through rivers and effluent disposal and decomposition. For marine environments, the sudden and constant growth of microplastics (plastics 1 µm to 5 mm in diameter), is of particular concern to top-predatory fish such as steelhead trout (Oncorhynchus mykiss), who passively or actively uptake microplastics while consuming prey. Previous research has demonstrated clear detrimental impacts of microplastic accumulation in bivalves, seabirds, and zebrafish, including decreased diet, reproduction rates, and metabolism, as well as increased rates of …

Instructors At A Crossroad: Perceptions Of Collaboration And Support Intersect With Intentions To Implement A Cure, Justin Berl

Dissertations and Theses

An ongoing crisis of student drop-off from undergraduate science, technology, engineering and mathematics (STEM) education has led to a sustained call over the last 15+ years for the increased implementation of updated practices in undergraduate STEM education. Though over the past few decades many researchers have developed and analyzed the efficacy of various evidence-based teaching practices (EBTPs) designed to improve the state of undergraduate STEM education throughout the country, the rate at which these EBTPs are implemented in undergraduate STEM classrooms remains low.

In order to better understand the specific factors that affect individual instructors' efforts to implement EBTPs, we …

Resistance To Dna Interstrand Crosslinks In Escherichia Coli Arises Through Prevention Rather Than Repair, Travis Kim Worley

Dissertations and Theses

DNA interstrand crosslinks are particularly lethal lesions that form in DNA when certain molecules intercalate between complementary strands of DNA and form covalent bonds with both strands. Once formed, these lesions present an absolute block to replication and transcription, ultimately resulting in cell death. Because of this lethality, chemicals that form DNA interstrand crosslinks are found in nature as defensive chemicals produced by plants and microbes. Moreover, crosslinking agents have proven effective the treatment of dysplastic conditions and are often first line chemotherapeutics.

However, cancer cells can become resistant to DNA interstrand crosslinks. Unlike other DNA lesions, the double-stranded nature …

Similarities, Commonalities And Parallels In The Contributions Of Thorstein Veblen And Friedrich Nietzsche, John B. Hall

Economics Faculty Publications and Presentations

This inquiry seeks to establish that similarities, commonalities, and parallels can be identified in selected contributions advanced by Thorstein Veblen and Friedrich Nietzsche. In the main, their commonness is noted to appear in the critical approaches that also includes expressing deep-seated skepticism regarding the course to modernity, singling out institutions ruling society, and especially the economy—in the case of Veblen. Specialized in Philology, as Nietzsche extolls his Dionysian orientation this inquiry introduces the idea that Veblen’s foundation for his distinctly critical approach to ruling institutions also reflects a Dionysian perspective. In Thus Spoke Zarathustra (1883-85) Nietzsche introduces a character whom …
