Homelessness Research & Action Collaborative Publications and Presentations

This report presents findings from Portland State University’s first housing and food insecurity survey of students and employees. It was conducted by The Homelessness Research & Action Collaborative (HRAC), a center formed to help address homelessness and its negative impact on individuals, families, and communities, with an emphasis on communities of color. Reducing homelessness in the PSU community was one of the foundational goals of the center, and this survey is an important step in that work.

This report examines the rates of housing insecurity, homelessness, and food insecurity among students and employees disaggregated by race and additional factors to …

Circuits Of Mobile Workers In The 19th-Century Central Balkans, Evguenia Davidova

International & Global Studies Faculty Publications and Presentations

This article compares the geographic and social mobility of two “lesser known” groups of workers: merchants’ assistants and maidservants. By combining labor mobility, class, and gender as categories of analysis, it suggests that such examples of temporary and return migration opened up new economic possibilities while at the same time reinforcing patriarchal order and increasing social inequality. Such transformative social practice is placed within the broader socio-economic and political fabric of the late Ottoman and post-Ottoman Balkans during the “long 19th century.”

Reframing Native Knowledge, Co-Managing Native Landscapes: Ethnographic Data And Tribal Engagement At Yosemite National Park, Rochelle Bloom, Douglas Deur

Anthropology Faculty Publications and Presentations

Several Native American communities assert traditional ties to Yosemite Valley, and special connections to the exceptional landmarks and natural resources of Yosemite National Park. However, tribal claims relating to this highly visible park with its many competing constituencies—such as tribal assertions of traditional ties to particular landscapes or requests for access to certain plant gathering areas—often require supporting documentation from the written record. Addressing this need, academic researchers, the National Park Service and park-associated tribes collaborated in a multi-year effort to assemble a comprehensive ethnographic database containing most available written accounts of Native American land and resource use in Yosemite …

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 …

From Theory To Practice: Gathering Evidence For The Validity Of Data Collected With The Interdisciplinary Science Rubric (Idsr)., Brie Tripp, Erin E. Shortlidge

Biology Faculty Publications and Presentations

In a world of burgeoning societal issues, future scientists must be equipped to work inter-disciplinarily to address real-world problems. To train undergraduate students toward this end, practitioners must also have quality assessment tools to measure students' ability to think within an interdisciplinary system. There is, however, a dearth of instruments that accurately measure this competency. Using a theoretically and empirically based model, we developed an instrument, the Interdisciplinary Science Rubric (IDSR), to measure undergraduate students' interdisciplinary science thinking. An essay assignment was administered to 102 students across five courses at three different institutions. Students' work was scored with the newly …

The Almohad: The Rise And Fall Of The Strangers, David Michael Olsen

Dissertations and Theses

The Almohad (1120-1269) displaced the Almoravid dynasty (1040-1147) as the rulers of the Maghreb and Andalusia in 1147 and created the largest Berber kingdom in history. They conquered the first indigenous rulers of the Maghreb by aggregating the Masmuda tribes from the High Atlas Mountains and enlisting the Zenata and Arab tribes from the Northern Maghreb. The Almohad rule built upon the existing Almoravid infrastructure; however, their cultural, administrative, and military approach entailed a more integrated tribal organization, centralized authority, and an original Islamic ideology. In creating this empire they envisioned the Maghreb as a consolidated political center and not …

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 …

Designing A More Effective Mri Contrast Agent: Investigation Into Various Functionalization Strategies For Targeted Imaging, Lauren Nicole Rust

Dissertations and Theses

Magnetic resonance imaging (MRI) is a medical imaging technique that provides high-resolution images used for diagnostic medicine while maintaining a superior safety profile compared to other radiative techniques. The administration of gadolinium-based contrast agents (GBCAs) improves the diagnostic power of MRI and have been used clinically for over three decades. Although GBCAs are effective at improving the contrast in the image, their detection limits are high and require a large dose to generate an observable effect. This high dose is the consequence of the current available designs of clinical GBCAs; their structures are not tuned to generate optimal efficacy. Efficacy …

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 …

Distribution, Geochronology, And Petrogenesis Of The Picture Gorge Basalt With Special Focus On Petrological Relationships To The Main Columbia River Basalt Group, Emily Bogdan Cahoon

Dissertations and Theses

The Columbia River Basalt Group (CRBG) is the youngest and volumetrically smallest continental flood basalt exposed across the Pacific Northwest, USA. Similar to other large igneous provinces, the majority of material erupted during the initial 1 million years of activity, these lavas are subdivided into four main-phase units. The Picture Gorge Basalt (PGB) is the only main-phase unit of the CRBG whose age is not precisely known and understanding of PGB petrogenesis is largely based on a limited number of samples when compared with other main-phase units. It is suggested that a time gap of over 0.5 myr existed between …

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 …

Numerical Model Of A Radio Frequency Ion Source For Fusion Plasma Using Particle-In-Cell And Finite Difference Time Domain, Augustin L. Griswold

University Honors Theses

Radio frequency (RF) plasma sources are common tool for application and study, and of particular interest for inertial electrostatic (IEC) fusion. Computational analysis is often carried out using particle in cell (PIC) methods or finite difference time domain (FDTD). However, a more holistic analysis is necessary as the particle distribution is highly dependant on the fields created by the plasma source. Herein, an analysis of a particular planar RF electrode with deuterium gas is provided which covers the fields and the particle behaviour using first FDTD then PIC. Further applications are discussed as well as further directions for this study.

Late-Night Political Comedy's Impact On Audience Political Attentiveness, Public Opinion, And Civic Engagement, Molly J. Olmstead

University Honors Theses

This thesis examines the relationship between late-night comedy news shows and their audiences, in terms of how they impact public opinion, political attentiveness and civic engagement. It looks at how the genre of late night political comedy is not a monolith, and neither is its audiences, and addresses the different ways these two interact with one another. Through an in-depth literature review, this thesis finds that late night political comedy has the most impact on politically inattentive audiences who end up learning about politics inadvertently, and that the jokes featured on these shows actively primes these viewers to hold certain …

Dynamic Through-Silicon Via Clustering In 3d Ic Floorplanning For Early Performance Optimization, Sucheta Mohapatra

Dissertations and Theses

Through-silicon via (TSV)-based three-dimensional integrated circuits (3D ICs) are expected to be the breakthrough technology for keeping up with the scaling trends of Moore's law, while also offering the unique opportunity for functional diversification through heterogenous integration. TSVs are vertical metal interconnects enabling communication across stacked and thinned dies. The dramatic reduction in global wirelength and chip footprint in 3DICs, directly improves delay, device density, bandwidth and routing congestion. Even with the current maturation of TSV process, the roadmap for industry adoption of 3DICs remains largely uncertain due to lack of standardized 3D tools capable of handling the sheer complexity …

Investigating The Needs Of Foreign Language Learners Of Tuvan, Rossina Soyan

World Languages and Literatures Faculty Publications and Presentations

Where do you start the course design for a minority language? One starting point is identifying and surveying a community of possible learners. This paper explores the needs of learners of Tuvan, a language spoken primarily in the Republic of Tuva, Southern Siberia, Russia. The study was conducted in two steps: an online questionnaire (March 2019) and semi-structured interviews (April 2019). The results showed a limited interest in Tuvan as a foreign language (13 responses) on the one hand, but a long-standing one on the other, more than two decades in some cases. The identified learner needs fell into three …

A Land Of Poets And Warriors: The Connection Between Warrior Culture And Bardic Culture In Medieval Wales C. 1066-1283, Sarah Lynn Alderson

Dissertations and Theses

Wales in the Middle Ages was a region both divided by war and united by culture. Frequent raids from the Hiberno-Irish, Scandinavians, and Flemish threatened Wales from the outside, while the kings within the borders of Wales fought for supremacy. During the late eleventh century, William the Conqueror made his way to the Welsh border in an attempt to secure his fledging kingdom. Under the premise of protecting his borders, William established the first March of Wales on the eastern border of Wales in 1087. This started the slow process of Anglo-Norman expansion and colonization into Wales.

The Welsh maintained …

Battle Of The Buttercups: Investigating Hybrid Zone Dynamics In A Ranunculus Species Complex, Jessica Persinger

Dissertations and Theses

Plants pose a well-known challenge to the biological species concept because hybridization is a common occurrence. Range dynamics have a crucial role in determining whether species are given the opportunity to interbreed or not. Successful hybridization can be of particular concern when considering range-limited species and their persistence. In my thesis research, I examine the apparent hybrid zone between the southern Oregon endemic Ranunculus austro-oreganus, a candidate threatened species due to its limited range, and its widespread congener, Ranunculus occidentalis, whose range spans from California to Alaska. The discovered contact zone was recognized in populations which contained apparent …

The Experiences Of Teachers Successfully Teaching Reading To Black Students, Kevin Michael Walker

Dissertations and Theses

Racist laws and subsequent educational policies and practices have resulted in schools in the United States failing to teach Black students reading. Historically, a racial achievement gap in elementary reading has existed throughout the history of the United States and has persisted to current times. As the population of students of color increases in the United States, we must investigate how teachers create equitable educational outcomes for students who have been historically underserved and oppressed by our education system. Teachers who are successful in ensuring our Black students have the opportunity to experience success in reading are actively disrupting the …

Novel View Synthesis - A Neural Network Approach, Hoang Le

Dissertations and Theses

Novel view synthesis is an important research problem in computer vision and computational photography. It enables a wide range of applications including re-cinematography, video enhancement, virtual reality, etc. These algorithms leverage a pre-acquired set of images taken from a set of viewpoints to synthesize another image at a novel viewpoint as if it was captured by a real camera. To synthesize a high-quality novel view, these algorithms often assume a static scene, or the images were captured synchronously. However, the scenes in practice are often dynamic, and taking a dense set of images of these scenes at the same moment …

An Introductory Overview Of The Koyukon (Athabaskan) Verb, Jonathan K. Vincent

University Honors Theses

The Athabaskan languages of western North America are notorious for exhibiting highly complex verbal morphology. Koyukon, a language spoken along the Yukon River in Alaska, and a member of the Northern branch of the Athabaskan family, is one such example. This overview seeks to introduce students and language practitioners to the theoretical fundamentals of Koyukon's verbal morphology, including the parts that constitute the discontinuous verbal base, or 'verb theme,' as well as the inflectional and derivational processes under which a verb theme may go in order to render morphologically complex surface forms with richly engineered meaning. These principles are amply …

The Performativity And Dynamics Of H.P. Grice's "Logic And Conversation": An Interdisciplinary Re-Conceptualization, Linnea Alexander

University Honors Theses

The following paper covers an interdisciplinary examination and re-conceptualization of philosopher H.P. Grice's Logic and Conversation. By way of interdisciplinary analysis and theory building, this paper breaks down Grice's philosophical understandings of conversational pragmatics as well as significant components of speech act theory, as put forth by philosopher J. L. Austin and revisited by J. R. Searle, and interactive frame theory as understood in sociocultural linguistic anthropology by Deborah Tannen and Cynthia Wallat. It interrogates shortcomings of Grice’s understanding of conversation and draws from speech act and frame theory to fill these shortcomings and expand on Grice's original …

In August 2005, Hurricane Katrina brought upon the city of New Orleans, LA one of the costliest natural disasters in U.S. history. This paper looks at how hospitals were prepared before Katrina, responded to, and grappled with the aftermath of this natural disaster. In the aftermath of Katrina, careful investigation of the healthcare system along with its hospitals, physicians, patients, and residents allow us to take innovative measures and provide guidance to create recommendations to better monitor and care for individuals in the future. Frameworks of resilience theories, studies, and recommendations display how and why disaster planning is essential. The …

Synthesis And Assessment Of Radiotherapy-Enhancing Nanoparticles, Hayden Winter

Dissertations and Theses

Radiation Therapy (RT) is a common treatment for cancerous lesions that acts by ionizing matter in the affected tissue, causing cell death. The disadvantage of RT is that it is most often delivered via an external beam of radiation which must pass through healthy tissues to reach the target site, ionizing matter within healthy tissues as well. To address this drawback, techniques are being developed for increasing RT-induced cell death in a target tissue while minimizing cell death in surrounding tissues. This effect is known as radiation dose enhancement or RT enhancement.

The approach to RT enhancement studied in this …
