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 …

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 …

Metabolomics Analysis Of Annual Killifish (Austrofundulus Limnaeus) Embryos During Aerial Dehydration Stress, Daniel Zajic, Jason Podrabsky

Biology Faculty Publications and Presentations

The annual killifish, Austrofundulus limnaeus, survives in ephemeral ponds in the coastal deserts of Venezuela. Persistence through the dry season is dependent on drought-resistant eggs embedded in the pond sediments during the rainy season. The ability of these embryos to enter drastic metabolic dormancy (diapause) during normal development enables A. limnaeus to survive conditions lethal to most other aquatic vertebrates; critical to the survival of the species is the ability of embryos to survive months and perhaps years without access to liquid water. Little is known about the molecular mechanisms that aid in survival of the dry season. This study …

No Water, No Problem: Stage-Specific Metabolic Responses To Dehydration Stress In Annual Killifish Embryos, Daniel E. Zajic, Jonathon P. Nicholson, Jason Podrabsky

Biology Faculty Publications and Presentations

Annual killifish survive in temporary ponds by producing drought-tolerant embryos that can enter metabolic dormancy (diapause). Survival of dehydration stress is achieved through severe reduction of evaporative water loss. We assessed dehydration stress tolerance in diapausing and developing embryos. We measured oxygen consumption rates under aquatic and aerial conditions to test the hypothesis that there is a trade-off between water retention and oxygen permeability. Diapausing embryos survive dehydrating conditions for over 1.5 years, and post-diapause stages can survive over 100 days. Diapausing embryos respond to dehydration stress by increasing oxygen consumption rates while post-diapause embryos exhibit the same or reduced …

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 …

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 …

What Makes Cents? How Uber Shapes Municipal On-Street Parking Revenue, Anne Brown, Benjamin Y. Clark

TREC Final Reports

Autonomous vehicles (AVs) will challenge cities in many ways that are critical to address before widescale adoption. In particular, AVs may upset municipal budgets as they upend traditional auto-related funding streams like registration fees and parking revenues. This research begins to quantify the potential financial impacts of AVs by analyzing current associations between transportation network company (TNC) trips—often viewed as a precursor of AVs—and parking revenue. This report uses TNCs as a proxy for future AV travel to examine the connections between trip-making and on-street parking occupancy and revenue. Specifically, we use Uber trip data along with built environment and …

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Whoonga is a smoked heroin-based street drug that first emerged in South Africa a decade ago. While previous scientific reports suggest that use is growing and youth are particularly vulnerable, trajectories of initiation are not well characterized. Methods: In 2015, 30 men undergoing residential addiction treatment for this smoked heroin drug in KwaZulu-Natal, South Africa participated in semi-structured interviews about their experiences using the drug. Interview data were coded using qualitative content analysis. Results: Participant trajectories to initiating smoked heroin were “vertical” in the context of marijuana use or “horizontal” in the context of other hard drug use. Participants …

The Scicommdiversity Travel Fellowship: The Challenge Of Creating A Sustainable Intervention, Alberto I. Roca, Cynthia-Lou Coleman, Tara S. Haelle, Danielle N. Lee

The first two years of the …

The Experience Of Female Caregivers In The Kingdom Of Saudi Arabia, Nouf Albugami

Dissertations and Theses

In the Kingdom of Saudi Arabia ("KSA"), a minimal amount of research concerning the availability and level of social support specifically targeting the female caregiver has been conducted. Moreover, the extent to which social support has helped alleviate both the physical and psychological stress of caregiving has been studied very little, if at all. In light of this limited amount of research, the goals of this study are to investigate the following two questions: (1) What is the experience of female caregivers with chronically ill children in KSA, and (2) What is the nature and availability of social support among …

Literatura Viva: Formas De Conocer La Literatura Y Agricultura Desde Chiapas, Jesse Nichols

Dissertations and Theses

Literatura Viva reflects the links between agriculture and literature in Chiapas, Mexico, demonstrating how the ways of knowing the environment which are culturally expressed through literature and the practices of sustainable agriculture are deeply linked. It argues that the experience of the agricultural working class is central not just to a physical movement towards tangible agricultural change but to a society's ability to understand its socio-cultural and natural environment. The thesis first explores indigenous literature, then agricultural practices and finally educational movements which seek to express pluriversal understandings and ways of interacting with the planet. It argues that these understandings …

Mixed Plate: Exploring Multiracial Student Identities Within Higher Education, Haley K. M. Okamoto

PSU McNair Scholars Online Journal

Race has primarily been studied from a monoracial perspective, which prohibits multiracial individuals from expressing themselves because their racial identity does not fit into the neatly, pre-established monoracial categories. Previous research has found that multiracial students experience life in ways that are unique compared to their monoracial peers. Multiracial students are often required to conform to socially constructed monoracial boxes and have negative experiences surrounding racial identity development, racism/microaggressions, and lack of demographic categorization. The multiracial population in America is steadily growing, and if current trends persist, will only continue to do so. As a result, an increased number of …

Short- And Long-Term Impacts Of A Deliberative Pedagogy In Introductory Biology And Chemistry Courses, Liz Rain-Griffith

Dissertations and Theses

There have been multiple national calls for curricular reform in college-level science, technology, engineering, and mathematics (STEM), including a need to instill democratic skills in students. Democratic skill building can be embedded in STEM classrooms through intentional "deliberative pedagogies" which include skills in: communication, collaboration, and application. We developed and implemented a deliberative pedagogy, Deliberative Democracy (DD), across introductory majors and non-majors biology courses and a majors chemistry course. In two separate studies, I took a longitudinal, qualitative research approach to understand introductory biology and chemistry students' experiences and perceptions of DD. For the first study, I tracked a cohort …

Panelists come from small programs with one or two people at the helm, as well as a program that includes people with diverse publishing backgrounds. We will discuss how our programs grew out of different priorities within our libraries, including a desire to address the high cost of textbooks for our students, as well as an interest in advancing open access more generally. Other things that shaped our programs include a repository platform that supported …

Working From Home: Analyzing The Autonomy Of App-Based Adult Content Creators, Jenna Depasquale

Dissertations and Theses

Accessibility to social media applications ("apps") has paved the way for a new addition under the umbrella of sex work: adult content creation. By selling self-produced photos and videos through mainstream social media apps, creators experience a specific set of conditions unlike the forms of sex work that have proceeded it. Through 13 semi-structured interviews, the following question is investigated: What aspects of app-based sex work heighten or threaten workers' senses of autonomy? Autonomy is defined as being able to exert control over one's work and the ability to work without external interruption. It is found that while the demand …

So Many Choices: An Experimental Study Of Digital Television Choice, Customization, And Satisfaction, Johanna Lee Hoener

Dissertations and Theses

Internet streaming television is increasingly available in society and is changing the way television is viewed by creating more and more choices for consumers. We no longer watch the same three channels on television, now the consumer controls when, where, and what to watch. Producers of this digital media landscape provide customization mechanisms that consumers also engage in, creating tailored presentations of content.

This study seeks to understand what the large landscape of choice does to our satisfaction in viewing choice and what part customization plays in that satisfaction through an experimental-survey design. Drawing from choice literature which points in …

Exploring The Factors Influencing Big Data Technology Acceptance, Mohammad Nayemur Rahman

Dissertations and Theses

The success of new technology depends on user acceptance. Therefore, discovering the antecedents of technology use is pivotal to overcoming the lack of user acceptance in the field of technology adoption. Factors of critical technological capability, in particular, are overlooked and largely neglected in the literature. Accordingly, the body of literature on the field of technology adoption is inconclusive as to which technological capability factors influence technology acceptance.

Big Data has received great attention in academic literature and industry papers. Most of the experiments and studies focused on publishing results of big data technologies development, machine learning algorithms, and data …

Crime Risk Near Reported Homeless Encampments: A Spatial Analysis, Kortney Lynn Russell

Dissertations and Theses

Those experiencing homelessness face several challenges in contemporary society including a higher risk of victimization compared to the general population. In order to offer effective intervention to protect members of this population, understanding the spatial relationship between homeless camps and crime is imperative. To provide the foundation for a future risk assessment used to identify camps with a higher risk of nearby victimization, this study assessed crime concentration in relation to reported homeless camps in Portland, Oregon. Utilizing two publicly available data sources, this study conducted spatial analyses on voluntarily reported homeless camp data from October through December 2019 and …

Perceptions Of Police Use Of Force At The Intersection Of Race And Pregnancy, Emma Elizabeth Lee Money

Dissertations and Theses

Attention surrounding forceful policing largely focuses on men's experiences, but Black women, even when pregnant, are also harmed by police use of force. Previous research demonstrating anti-Black biases in perceptions of police use of force toward men cannot be directly applied towards women, due to unique stereotypes of Black women and mothers. How do race and pregnancy influence perceptions of police use of force against women? It was expected that pregnancy would elicit more positive responses in the current study, but only when pregnant women were also White. Benevolent sexism (BS) and social dominance orientation (SDO) were tested as moderators …

Host-Dependent Differences In Replication Strategy Of The Sulfolobus Spindle-Shaped Virus Strain Ssv9 (A.K.A., Ssvk1): Infection Profiles In Hosts Of The Family Sulfolobaceae, Ruben M. Ceballos, Coyne Gareth Drummond, Carson Len Stacy, Elizabeth Padillo-Crespo, Kenneth M. Stedman

Biology Faculty Publications and Presentations

The Sulfolobus Spindle-shaped Virus (SSV) system has become a model for studying thermophilic virus biology, including archaeal host-virus interactions and biogeography. Several factors make the SSV system amenable to studying archaeal genetic mechanisms (e.g., CRISPRs) as well as virus-host interactions in high temperature acidic environments. Previously, we reported that SSVs exhibited differential infectivity on allopatric vs. sympatric hosts. We also noticed a wide host range for virus strain SSV9 (a.k.a., SSVK1). For decades, SSVs have been described as “non-lytic” double-stranded DNA viruses that infect species of the genus Sulfolobus and release virions via budding rather than host lysis. In this …

The Persistence Of Indigenous Markets In Mexico's 'Supermarket Revolution', Diana Christina Denham

Dissertations and Theses

This dissertation research investigates the paradoxical survival of Indigenous markets in the context of state-sponsored development strategies that privilege multinational retailers and rebrand Mexican cities as modern and globally competitive. I examine how Indigenous markets have survived the supermarketization (and, more precisely, Walmartization) of food retail that has taken hold in Mexico. Better known by their Nahuatl name tianguis, open-air Indigenous markets held in streets and public plazas predate the arrival of the first conquistadors and remain common across Mesoamerica today. My examination of tianguis in native language texts, colonial narratives, popular art, and mid-20th century newspapers demonstrates that …

“Decolonize” E-Literature? On Weeding The E-Lit Garden, Kathi Inman Berens

English Faculty Publications and Presentations

Berens asks: Should the e-literature community include third-generation works in collections, syllabi, databases, prizes? A related question: do third-gen makers have a role in “decolonizing” e-literature? Who or what “colonizes” e-lit? E-literature, like earlier avant gardes, began as a coterie and has become a scholarly field. Using the comparison of a field versus a walled garden, the essay examines critiques of e-literature and variations on field definitions. It ends with two ideas about how to "decolonize" e-literature; about how equity and inclusion work in tandem with decolonization, but are not the same thing; and why decolonization efforts are urgent in …

Social Media In Business-To-Business Marketing And Sales: Review Of Literature & Research Recommendations, Daniel Bello Manjarrez

University Honors Theses

Social media usage in business to business marketing and sales has been steadily rising since its advent in the late 2000s. Similarly, research surrounding social media in this context has increased, with specific focus on its usage, influence, and adoption from B2B marketers and salespeople. This focus has resulted in gaps in the literature, especially when regarding small and medium B2B enterprises. This review of literature provides a systemic understanding of the research landscape by identifying the theory, methods, context, and results of twenty-one peer-reviewed business marketing articles concerning social media. This review also proposes five key recommendations to inform …
