Reducing Transphobic Attitudes: A Cross-National Investigation Of College Students In Japan And The United States, Kazusa Seko

Dissertations and Theses

Transgender people routinely experience discrimination and mistreatment. Although transphobic attitudes vary from country to country, a more in-depth understanding of these attitudes is needed. Using a semi-structured online survey, this study investigates college students' attitudes toward transgender people in Japan and the United States, a cross-national comparison that aims to deepen our understanding of how transphobic attitudes are shaped and what opportunities exist to reduce transphobia amongst college students. Results show that Japanese students express more transphobic attitudes than U.S. students do; and that U.S. students had more experience with gender-based educational content and were more likely to know someone …

An Investigation Of Anti-Black Racism Libguides At Arl Member Institutions, Gemmicka Piper, Mahasin Ameen, M. Sara Lowe

Communications in Information Literacy

This study sought to analyze anti-Black racism LibGuides created by ARL member institutions to determine strengths and weaknesses of the guides based on LibGuides best practices. Institutional and LibGuide author demographic information were also gathered to determine correlations or trends, if any. Rubric evaluation of LibGuides found that guides were strongest in areas related to guide design, materials included on the guides, and links to resources. Guides were weakest in areas related to the framing of social justice and pedagogy. Results from this study have the potential to inform the structure and revision of social justice LibGuides at a time …

The Ejection Of Large Non-Oscillating Droplets From A Hydrophobic Wedge In Microgravity, Logan Torres, Mark M. Weislogel

Mechanical and Materials Engineering Faculty Publications and Presentations

When confined within containers or conduits, drops and bubbles migrate to regions of minimum energy by the combined effects of surface tension, surface wetting, system geometry, and initial conditions. Such capillary phenomena are exploited for passive phase separation operations in micro-fluidic devices on earth and macro-fluidic devices aboard spacecraft. Our study focuses on the migration and ejection of large inertial-capillary drops confined between tilted planar hydrophobic substrates (a.k.a., wedges). In our experiments, the brief nearly weightless environment of a 2.1 s drop tower allows for the study of such capillary dominated behavior for up to 10 mL water drops with …

Exploring The Potential Use Of Porous Silica Nanoparticles In Cest-Mri, Lydia Makotamo

Dissertations and Theses

Magnetic resonance imaging (MRI) is a widely used modality in diagnostics, treatment, and monitoring various conditions due to its ability to generate high-resolution images using non-ionizing radiation. The advent of contrast agents, which generally work by increasing the spin relaxation rate constants of water protons, has led to image enhancement. Despite the usefulness of this class of agents in diagnostic medicine, their inability to provide in-depth functional and anatomical information, coupled with their high detection limits, has led to new agents being explored.

Chemical exchange saturation transfer (CEST) presents an alternative route to generate signals via repetitive saturations transfers between …

Designing Environmentally Responsible And Highly Effective Bioorthogonally Functionalized Chiral Mri Contrast Agents, Karley Breann Maier

Dissertations and Theses

Magnetic resonance imaging (MRI) revolutionized diagnostic imaging and modernized the characterization of numerous diseases. The clinical success of MRI is in large part due to the employment of gadolinium-based contrast agents (GBCAs). Due to sensitivity limitations, GBCAs are indicated at markedly high dosages (~1 g Gd³⁺ per exam). The routine use of such large quantities of gadolinium poses significant health and environmental risks. There are growing concerns over the effects of dechelation of the metal in vivo and the possible effect of resulting gadolinium deposition. Concurrently, there is a rising awareness of gadolinium anomalies borne by GBCAs which undergo …

Mothers' Drinking Motives, Sheila Kathleen Umemoto

Dissertations and Theses

Increases in women's excessive alcohol use are leading to concerns about a developing public health problem since, for women, it takes fewer years and lower doses to develop a range of alcohol-induced health problems. Maternal status is generally considered protective against alcohol use; however, this effect is weakened by multiple social role strain, leading to higher stress and negative affect, and subsequent coping-related alcohol use. Given that the majority of mothers with young children are working or looking for work (72.3%; BLS, 2021), it is likely that the combination of competing demands and expectations associated with multiple roles of parent, …

Situate: An Agent-Based System For Situation Recognition, Max Henry Quinn

Dissertations and Theses

Computer vision and machine learning systems have improved significantly in recent years, largely based on the development of deep learning systems, leading to impressive performance on object detection tasks. Understanding the content of images is considerably more difficult. Even simple situations, such as "a handshake", "walking the dog", "a game of ping-pong", or "people waiting for a bus", present significant challenges. Each consists of common objects, but are not reliably detectable as a single entity nor through the simple co-occurrence of their parts.

In this dissertation, toward the goal of developing machine learning systems that demonstrate properties associated with understanding, …

Creativity In Science, Engineering, And The Arts: A Study Of Undergraduate Students' Perceptions, Dildora F. Beaulieu

Dissertations and Theses

Creativity is widely recognized as being invaluable for human development and a crucial 21^st century talent. Preparing students for an uncertain and complex world requires that higher education promote students' imagination, originality, curiosity, and flexibility and build their capacity to take risks to try new approaches to problem-posing and problem-solving. However, little is known about how undergraduates enrolled in different disciplines view creativity. This quantitative study at a university in the northwestern United States assessed how undergraduate students in different academic disciplines responded to an instrument on creativity measurement developed by Dlouhy (2012). The study asked: How do undergraduates …

The Draining Of Capillary Liquids From Containers With Interior Corners Aboard The Iss, Joshua Thomas Mccraney, Mark M. Weislogel, Paul Steen

Mechanical and Materials Engineering Faculty Publications and Presentations

In this work, we analyze liquid drains from containers in effective zero-g conditions aboard the International Space Station (ISS). The efficient draining of capillary fluids from conduits, containers, and media is critical in particular to high-value liquid samples such as minuscule biofluidics processing on earth and enormous cryogenic fuels management aboard spacecraft. The amount and rate of liquid drained can be of key concern. In the absence of strong gravitational effects, system geometry, and liquid wetting dominate capillary fluidic behavior. During the years 2010–2015, NASA conducted a series of handheld experiments aboard the ISS to observe “large” length scale capillary …

Institutional Theory In Sport: A Scoping Review, Jonathan Robertson, Mathew Dowling, Marvin Washington, Becca Leopkey, Dana Lee Ellis, Lee Smith

Business Faculty Publications and Presentations

Institutional theory has generated considerable insight into fundamental issues within sport. This study seeks to advance Washington and Patterson’s review by providing an empirical review of institutional theory in sport. We follow Arksey and O’Malley’s scoping review protocol to identify 188 sport-related institutional studies between 1979 and 2019. Our review provides evidence regarding the state of institutional scholarship within sport via an analysis of authorship, year, journal, methodology, method, study population, and use of institutional constructs (legitimacy, isomorphism, change, logics, fields, and work). Rather than a hostile takeover or a joint venture proposed in Washington and Patterson’s review, the relationship …

The Association Of Paid Medical And Caregiving Leave With The Economic Security And Wellbeing Of Service Sector Workers., Julia M. Goodman, Daniel Schneider

OHSU-PSU School of Public Health Faculty Publications and Presentations

Service-sector workers in the U.S. face extremely limited access to paid family and medical leave, but little research has examined the consequences for worker wellbeing. Our objective was to determine whether paid leave was associated with improved economic security and wellbeing for workers who needed leave for their own serious health condition or to care for a seriously ill loved one.

"We Had To Rely On Each Other": Voices Of Latinx Foster Youth With Experiences In Care With Siblings, Isabella B. Ginsberg

PSU McNair Scholars Online Journal

Relationships between members of sibling groups have been found to impact well-being for children who enter foster care (Herrick & Piccus, 2005). Being placed in stranger foster care is often challenging and can be traumatic with children reporting confusion, worry, and loss of identity and sense of belonging (Herrick & Piccus, 2005, Unrau et al, 2008). While there is some research that explores the experiences of siblings groups in foster care and others separately that examines Latinx children in foster care, there is very little information that looks into the potentially unique experiences of Latinx individuals who were in care …

Japanese-English Code-Switching By Postwar Speakers In Contemporary America, Andre John Shepherd

Dissertations and Theses

In her examination of Japanese-English bilingualism in Toronto, Nishimura (1995b) demonstrated that second-generation Japanese-Canadians varied their speech dependent on the audience they were addressing. According to her, the Japanese-Canadians spoke primarily in English to fellow second-generation speakers, while maintaining conversations in Japanese with those who had spent their formative years in Japan. However, when addressing audiences composed of both groups, they switched back and forth evenly between the two languages.

Following research done by Woolard (1989) on the effects of societal influences on language, the state of the Japanese-Canadians can be related to the breakup of the ethnic enclaves in …

Using Gis-Based Spatial Analysis To Determine Urban Greenspace Accessibility For Different Racial Groups In The Backdrop Of Covid-19: A Case Study Of Four Us Cities, Arun K. Pallathadka, Laxemi Pallathadka, Sneha Rao, Heejun Chang, Dorn Van Dommelen

Geography Faculty Publications and Presentations

As the United States leads COVID-19 cases on global charts, its spatial distribution pattern offers a unique opportunity for studying the social and ecological factors that contribute to the pandemic’s scale and size. We use a GIS-data-based approach to evaluate four American cities—Anchorage (Alaska), Atlanta (Georgia), Phoenix (Arizona), and Portland (Oregon) characterized by the significant composition of different racial and ethnic group populations. Building upon previous studies that investigated urban spatial inequalities using the environmental justice framework, we examine: (1) the relative racial vulnerability of Census Block Groups (CBG) and ZIP Code Tabulation Areas (ZCTA) to COVID-19 (2) green space …

Since the last report, emergency managers throughout Oregon have faced numerous disaster incidents, including the COVID-19 pandemic, ice storms, flooding, and some of the worst heat waves, drought conditions, and megafires on record, with the threat of more to come in the years ahead. After years of research and development, fueled by lessons learned from a catastrophic …

An Assessment Of Bicycle Detection Confirmation And Countdown Devices, Christopher Monsere, Sirisha Kothuri, David S. Hurwitz

PSU Transportation Seminars

For a person on a bicycle at intersections, trail crossings, or midblock locations that are signalized, knowing that they have been detected and how long they must wait to receive a green indication is valuable information. This presentation will summarize the findings from the online survey (1,048 responses), observed behaviors (2,428 persons on bicycle), and an intercept survey ( 234 persons) to understand blue light feedback devices and countdown timers at signalized intersections.

Findings suggest that the design where the blue light was embedded in the sign was more visible to cyclists and observed by higher proportions of cyclists in …

Autonomous Farming With Uavs, Pallavi Agrawal, Karthik Manjunath, Cherokee Rawls, Sujitha Raj Rajagopal, Riad Alharithi, Kamal Thapa

Engineering and Technology Management Student Projects

As the global need for food grows, agriculture is adapting autonomous farming techniques to scale in response. One of the most useful tools are UAVs (Unmanned Autonomous Vehicles), which are providing invaluable information and assistance to farmers. In some countries, UAVs are being rapidly embraced, while in others this progress is much slower. For a number of reasons, the United States has not broadly adopted this technology in assisting agricultural practices. In this article, we focus on the challenges companies and farmers are facing in making use of UAVs and what might be done to push this technology into widespread …

Fandom In The Digital Age: Examining Parasocial Relationships Between Fans And Music Artists On Instagram, Brittani Wert

University Honors Theses

With the rise of social media as a cultural staple in entertainment industries such as music, Instagram changes the landscape of the artist-fan connection and muddles the boundaries of parasocial relationships in a digital space. While a wealth of research exists on how fans perceive mediated relationships, the perspective of the artist and how they navigate this connectivity is missing from the discourse. This study builds on the current literature surrounding mediated artist-fan interactions and examines how music artists use Instagram to build strong, loyal relationships with fans through the lens of parasocial relationships. Through interviews with up-and-coming artists and …

Addressing And Supporting Mental Health Today: Society-Wide And In Hospital Emergency Departments, Kira La Sage

University Honors Theses

Mental health has become one of the most pressing public health issues of the 21st Century. Westernized societies offer much of their attention to childhood obesity, to COVID-19, to undiagnosed and diagnosed Americans living with diabetes. America even sees extended U.S. Senate hearings focusing on opioid use and abuse. Each of these concerns legitimately commands public health official attention, but what the world does not see is any level of sustainable attention given to emotional and mental health crises affecting tens of millions in Westernized countries. Suicide, the most serious of mental health crises, has become the second leading cause …

Understanding The Effect Of Dietary Palmitic Acid On Glycolysis During Innate Immune Memory In Macrophages, Khaleda A. Aqaei

University Honors Theses

Trained immunity is long-term innate immune memory induced by a primary stimulus, which leads to hyper-inflammation upon secondary stimulation with a homologous or heterologous ligand. Trained immunity is mediated by epigenetic and metabolic reprogramming of the target cell and leads to modification of gene expression and cellular function. Classically, trained immunity is initiated by β-glucans, an inflammatory molecule found on the exterior of fungal species. Interestingly, our lab has recently described that dietary fatty acids can initiate trained immunity, working through similar pathways as β-glucans. Specifically, our data show that a pre-treatment with a specific dietary saturated fatty acid (SFA), …

Gender Deviants: Subverting Regulatory Power In Medical Institutions, Ursa Nuffer-Rodriguez Mx.

University Honors Theses

Medical and psychiatric institutions have a long history of regulating and pathologizing the bodies of non-normative individuals. The harmful normativity of these institutions is particularly salient for trans* people pursuing gender-affirming medical care, as popular media representations of trans* identity reinforce narratives of certainty and aspirations towards cisgender standards of corporeality which rarely map onto authentic narratives of trans*ness. For the gender deviant subject, who conceives of hirself beyond these hegemonic notions of identity, navigating these institutions often requires a false projection of identity that fits the standard narrative, simply as a means to an end. In doing so, the …

An Automated Ar-Based Annotation Tool For Indoor Navigation For Visually Impaired People, Pei Du, Nirupama Bulusu

Computer Science Faculty Publications and Presentations

Low vision people face many daily encumbrances. Traditional visual enhancements do not suffice to navigate indoor environments, or recognize objects efficiently. In this paper, we explore how Augmented Reality (AR) can be leveraged to design mobile applications to improve visual experience and unburden low vision persons. Specifically, we propose a novel automated AR-based annotation tool for detecting and labeling salient objects for assisted indoor navigation applications like NearbyExplorer. NearbyExplorer, which issues audio descriptions of nearby objects to the users, relies on a database populated by large teams of volunteers and map-a-thons to manually annotate salient objects in the environment like …
