Entrainment Processes For A Jet In Cross-Flow: The Quantification Of Turbulent Contributions And Their Importance On Accurate Modeling, Graham Asher Freedland

Dissertations and Theses

A jet in cross flow (JICF) is examined experimentally by injecting a stream of air into crossing fluid with an aim into quantifying entrainment process and downstream evolution. The behavior of JICF is important to fields ranging from turbine-blade cooling to smokestack pollution and volcanic eruption dynamics. Existing simplified volcanic plume models are tested; most importantly, the near-field contributions of complex interconnected vortex systems, which present significant uncertainties because they assume negligible turbulence. While jets in irrotational cross-flow have been investigated, this analysis has focused on the interaction between a turbulent jet in low and highly turbulent cross-flow created by …

Identification Of Degradation Products Formed From Glycerol And Terpenes In Aromatherapy Vaporizers, Alisha Ortiz

University Honors Theses

Degradation chemistry has been widely studied to assess the safety of aerosols in many fields. The study herein investigates the degradation products formed from MONQ personal aromatherapy devices- a new non-nicotine aromatherapy vape pen device on the market. These pens are marketed to alleviate symptoms of an unrecognized medical syndrome called “terpene deficiency”. These pens contain a glycerin (GL), or glycerol (VG), base and a blend of terpene-rich essential oils. Previous studies have investigated the degradation of both VG and terpenes and have shown that concerning compounds are released in the gas phase, including benzene, benzaldehyde, methacrolein and methyl vinyl …

Winning The Fight For Better Bus Service, Steven Higashide

PSU Transportation Seminars

The "right to the city" depends on the right to access the city, and U.S. regions are marked by profoundly unequal access. One of the clearest manifestations of this is the state of U.S. bus transit. Bus service is simple to improve and has vast potential to better people's lives, but has been constrained by the racist planning and politics that shape every American city.

How can we fulfill the promise of better buses and create abundant transit networks that expand access to opportunity? In this seminar, Higashide unpacks the elements of effective bus service – and cites examples from …

Aligning Food Environments With Institutional Values: A Mixed Methods Study Of Oregon Health Care Organizations, Elizaveta Walker

Dissertations and Theses

A major driver of the obesity epidemic is obesogenic food environments, characterized by nutrient-poor and energy-dense foods that saturate the collective physical, economic and sociocultural conditions that influence nutritional status. Food environments in organizations such as hospitals and public health agencies warrant special consideration given their health-focused mission. Improving food environments within health care settings has been highlighted by the Centers for Disease Control and Prevention (CDC) as one of seven key strategies to prevent obesity. However, most of the refereed literature examining healthy food environment policies (HFEPs) within hospitals focuses on the inpatient dietary environment, leaving a paucity of …

Juveniles In The Interrogation Room: Defense Attorneys As A Protective Factor, Caitlin N. August, Kelsey S. Henderson

Criminology and Criminal Justice Faculty Publications and Presentations

Juveniles are more susceptible in the interrogation room than adults, due to a host of vulnerabilities that put them at risk. Scholars have suggested that requiring the presence of a defense attorney during interrogations can protect juveniles from making an unintelligent waiver; variations of this type of policy have been mandated in some states across the United States (e.g., Illinois and California). The current study takes an exploratory, qualitative approach to examine how defense attorneys may act as a protective factor in the interrogation room. We interviewed 19 juvenile defenders using a semi-structured interview method; questions focused on experiences in …

Not A Blank Slate: Information Literacy Misconceptions In First-Year Experience Courses, Michelle Keba, Elizabeth Fairall

Communications in Information Literacy

Information literacy is the primary instructional focus of many librarians. With the development of a core set of information literacy threshold concepts, librarians often strive to impart these concepts to undergraduate students during their years of study. However, when students come to school, they are not blank slates. They arrive with preconceived ideas or misconceptions which can impede this process. In this article, the authors report on the results of focus groups held with first-year students at a private, liberal arts university. During the focus groups, participants were asked to share their perceptions of the misconceptions identified by Hinchliffe et …

Analyzing Information Sources Through The Lens Of The Acrl Framework: A Case Study Of Wikipedia, Trudi E. Jacobson

Communications in Information Literacy

Might the ACRL Framework for Information Literacy for Higher Education be used to analyze information resources? Would a Framework-focused analysis of one commonly used resource, Wikipedia, yield valuable insights for the teaching and learning of key information literacy concepts? Each of the six frames is explored in the light of Wikipedia, and metaliteracy, a founding principle of the Framework, is introduced when it provides additional scaffolding in connection with the goals of a particular frame as a way to enhance student learning opportunities. There are a number of components in Wikipedia that align with the Framework …

Professional Development For Research-Writing Instructors: A Collaborative Approach, Melissa Bowles-Terry, Kaitlin Clinnin

Communications in Information Literacy

Writing programs and academic libraries are frequent collaborators based on shared concerns about writing and research. However, in these collaborative relationships librarians often share their expertise with writing program administrators and individual instructors without developing the information literacy expertise of the majority of writing program instructors. At the University of Nevada, Las Vegas, the library instruction program and the writing program recognized that by facilitating collaborative professional development, they could together provide enhanced support for instructors teaching research-based writing courses. The authors present a case study of their local professional development institute that developed writing instructors’ information literacy confidence and …

Neighborhood Air Quality Impact From Construction Site Emissions In Portland, Or, Lyndsey Boyle

Environmental Science and Management Professional Master's Project Reports

Research has shown that diesel particulate matter, including black carbon, is harmful to human health and has climate warming properties. Emissions from off-road engines, specifically construction, are a major source of diesel particulate matter in Portland, OR. There has been little done to manage the impact that construction has on local air quality. This project included a review of recent literature on the health and climate warming effects of particulate matter and black carbon, a modeling study to better understand what the major sources of diesel particulate matter are in Oregon, and a review of current research on construction site …

Survey results point to the influence of the Association of College and Research Libraries Framework in the community college context, the challenges librarians face as they work to implement it, and their successes in doing so. These data reveal opportunities to support and improve instruction and to prepare future librarians to work successfully in community college contexts.

“We Were Queens.” Listening To Kānaka Maoli Perspectives On Historical And On-Going Losses In Hawai’I, Antonia R.G. Alvarez, Val. Kanuha, Maxine K.L. Anderson, Cathy Kapua, Kris Bifulco

School of Social Work Faculty Publications and Presentations

This study examines a historical trauma theory-informed framework to remember Kānaka Maoli (Native Hawaiian) and lesbian, gay, bisexual, transgender, queer, and/or māhū (LGBTQM) experiences of colonization in Hawai`i. Kānaka Maoli people and LGBTQM Kānaka Maoli face health issues disproportionately when compared with racial and ethnic minorities in Hawai’i, and to the United States as a whole. Applying learnings from historical trauma theorists, health risks are examined as social and community-level responses to colonial oppressions. Through the crossover implementation of the Historical Loss Scale (HLS), this study makes connections between historical losses survived by Kānaka Maoli and mental health. Specifically, this …

Smoking Behaviors In Patients Offered Lung Cancer Screening, Sara Elizabeth Golden

Dissertations and Theses

In the United States, smoking causes preventable diseases, including lung cancer, which is the leading cause of cancer deaths. Improving smoking cessation rates is important to decrease lung cancer deaths. Health care visits with a discussion about lung cancer screening (LCS) may help in increasing prevalence of smoking cessation. Importantly, insurers now require clinicians to have a shared decision-making discussion with patients that includes discussion of smoking abstinence before they can receive an LCS scan (i.e., a low-dose computed tomography scan). This discussion may represent a unique opportunity to encourage smoking cessation since it may prompt positive smoking behavior change. …

Microplastics In Pacific Northwest Bivalves: Ecological Prevalence, Harvester-Consumer Exposure, And Aquarium Exhibit Outcomes, Britta Rahel Baechler

Dissertations and Theses

Up to 23 million metric tons of mismanaged plastics enter the global ocean annually. Microplastics (MPs;<5mm) degrading. MPs leak into the environment and now pervade every corner of the earth, with implications for animal, plant, ecosystem and human health. It is important to understand localized environmental MP prevalence, distribution and organismal uptake in order to determine the extent of MP pollution, and ultimately unlock solution sets to reduce transmission of MPs into the natural world. In Chapter 2, I quantified MP types, concentrations, anatomical burdens, geographic distribution, and temporal differences in Pacific oysters (Crassostrea gigas) and Pacific razor clams (Siliqua patula) from 15 coastal sites in Oregon. Both of these species are integral to culture, economy, gastronomy and food security along the United States West Coast. In Chapter 3, I quantified MPs in Pacific razor clams collected from 8 Olympic Coast, Washington sites, administered questionnaires to recreational razor clammers and subsequently estimated annual MP exposure of those Olympic Coast razor clam harvester-consumers surveyed. In Chapter 4, I designed and installed an educational ocean plastic …

Methodologies To Quantify Transit Performance Metrics At The System-Level Using High-Resolution Gps, Stop-Level, And Gtfs Archived Transit Data, Travis Bradley Glick

Dissertations and Theses

Performance metrics have typically focused at two main scales: a microscopic scale that focuses on specific locations, time-periods, and trips; and, a macroscopic scale that averages metrics over longer times, entire routes, and networks. When applied to entire transit systems, microscopic methodologies often have computational limitations while macroscopic methodologies ascribe artificial uniformity to non-uniform analysis areas. These limitations highlight the need for a middle approach.

This dissertation presents a mesoscopic analysis based around timepoint-segments, which are a novel application of an existing system for many transit agencies. For this research, routes are divided into a consecutive group of bus stops …

Balance On Every Ledger: Kwakwaka’Wakw Resource Values And Traditional Ecological Management, Douglas Deur, Kim Recalma-Clutesi, Chief Adam Dick

Anthropology Faculty Publications and Presentations

This chapter illustrates the core environmental values of the Kwakwaka’wakw (Kwakiutl) people on the Pacific coast of Canada to explore how they manifest in the traditional management of coastal natural resources. The authors’ survey of environmental values is based on the authentic knowledge of Chief Adam Dick, a co-author of the chapter. The chapter argues that talking about Indigenous Knowledge without the broader context of environmental values can lead to serious scholarly misunderstandings and insists that long-term collaborations between academic researchers and specialized knowledge holders from Indigenous communities is necessary in order to represent Indigenous Knowledge accurately.

This chapter illustrates …

Aryne-Guided C-H Functionalization Of Benzenoid Rings Using Diaryliodonium Salts, Aleksandra Nilova

Dissertations and Theses

The benzenoid core is a frequent and irreplaceable component of biologically active molecules. Structure function relationship of these compounds has been broadly analyzed and presented in numerous literature reports. Herein, we augmented existing knowledge by a broad analysis of the benzenoid substitution patterns in small molecule active pharmaceutical ingredients approved by the FDA. Our findings reveal a strong correlation that the most represented substitution patterns are those achieved via S_EAr. Despite the rapid development of methods to functionalize benzenoid rings, the lack of synthetic methodologies to access sterically and electronically unfavorable positions is highlighted. We sought to establish …

“Rapunzel, Rapunzel, Lanza Tu Pelo”: Storytelling In A Transcultural, Translanguaging Dialogic Exchange, Erin E. Flynn

School of Social Work Faculty Publications and Presentations

In this study, we examined story circles to understand how the small‐group activity supports and shapes the storytelling of young students in multicultural, multilingual preschool classrooms. Through a representative example, we show how language development unfolds in the context of a transcultural and translanguaging dialogic exchange of stories. We describe features of increasing linguistic complexity present in students’ storytelling as they established affinity‐affirming connections over ideas, shared ways of languaging, and shared ways of storytelling. By examining changes in one student’s storytelling in the context of a mixed‐language story circle group, we offer insights into both language development and features …

Outcome Analysis Of Tranexamic Acid In Thromboembolic Complications And Coagulation Factors, Hunter A. Mccorkle

University Honors Theses

Background: Tranexamic acid (TXA) is an antifibrinolytic used for controlling hemorrhaging in patients. It’s regular application in trauma centers could be vital in reducing all-cause mortality for hemorrhaging secondary to traumatic injury but there are still concerns about possible side effects and populations at greater risk of complications. The possible use of predictive measures such as thrombelastography (TEG) and conventional coagulation testing (CCT) in detecting early markers of TXA risks are still unconfirmed, and unfortunately there is a time restriction of 3 hours for TXA to be effective in reducing all-cause mortality.

Objective: Our objective is to observe outcomes of …

Use Of Carbon Fiber Reinforced Polymer (Cfrp) Including Sheets, Rods, And Ropes In Strengthening And Repairing Long Reinforced Concrete Columns, Yasir Matloob Saeed

Dissertations and Theses

The use of FRP materials in strengthening and repairing of reinforced concrete (RC) structures has increased in the past two decades. Recently, FRP materials have become one of the most used materials in rehabilitation engineering. For seismic retrofitting of RC structures, usually the process involves strengthening or repairing the vertical support elements of the buildings or bridges. Several studies focused on the use of FRP materials in strengthening and repairing RC columns. Externally bonded (EB) FRP sheets or laminates and near-surface-mounted (NSM) FRP rods have been used for enhancing the strength and ductility of RC columns. Although glass FRP (GFRP) …

Fem Or Foe?: Non-Communal Women Who Report Sexual Harassment Receive Fewer Career Advancement Opportunities, Katherine A. Werth, Larry R. Martinez, Heather A. Firestone, Timothy A. Carsey

University Honors Theses

Sexual harassment is an ever-important topic to organizations, but there is currently a gap in the literature regarding career outcomes for women who report sexual harassment. Past research has discovered that masculine women get harassed more than feminine women and that masculine women have a better chance at career advancement opportunities than feminine women, but there has yet to be any focus on how the gender personality of a sexual harassment survivor relates to organizational success after a sexual harassment report. This study aims to help address this gap by drawing from the stereotype content model (Cuddy, Glick & Fiske, …

Examining The U.S. Wars On Vietnam, Laos, And Cambodia As The Production Of Neo-Colonialism, Aiden Gregg

University Honors Theses

I interrogate the colonial and neo-colonial histories of the U.S. wars on Vietnam, Cambodia, and Laos within the context of racialized and gendered labor accumulation, the production of difference through violence as a legitimation of colonial extraction, and ongoing neoliberal economic coercion. I examine genocide and ecocide as interdependent processes in the production of dependency and underdevelopment. I reject a common narrative of temporal and spatial disconnection which separates the wars from current economics and examine the violences which both produce and result from an economy based on growth.

Six Feet Of Distance Between Belonging: Expansions And Maintenance Of Citizenship During Covid-19, Johnathon Daniel Vargas

University Honors Theses

Citizenship is the dominant 'political regime of belonging' that is coupled with rights and access to necessary material resources. This paper reviews the dimensions of citizenship, its connection to the nation-state, and analytical approaches to belonging. The review of literature is then applied to an analysis of how COVID-19 has challenged notions of citizenship by revealing maintenance strategies and enactments of belonging in Portland, Oregon and the surrounding region. This paper uses qualitative research to analyze events, communication, activities, and conditions of those who lack citizenship, mediated through local media. Data collected from the first 3 months of the COVID-19 …

Importance Of Interpersonal Relationships In Cbgt, Alexxa Badley

University Honors Theses

A literature review was conducted to answer the question, can CBGT, and its emphasis on interpersonal relationships bolster the treatment of depression in adolescents? Adolescents were defined as anyone between the ages of 13-17, and depression was diagnosed by the DSM-V. It was found that CBGT had strong effectiveness in the treatment of depression, lowering symptoms across the board. Teens found solidarity in having others that could relate to them and their personal experiences. Potential downfalls were the fact that time management was crucial to better treatment, making sure everyone had a chance to speak, as well as strong communication …

A Posteriori Error Estimates For Maxwell's Equations Using Auxiliary Subspace Techniques, Ahmed El Sakori

Dissertations and Theses

The aim of our work is to construct provably efficient and reliable error estimates of discretization error for Nédélec (edge) element discretizations of Maxwell's equations on tetrahedral meshes. Our general approach for estimating the discretization error is to compute an approximate error function by solving an associated problem in an auxiliary space that is chosen so that:

-Efficiency and reliability results for the computed error estimates can be established under reasonable and verifiable assumptions.

-The linear system used to compute the approximate error function has condition number bounded independently of the discretization parameter.

In many applications, it is some functional …

The Impact Of Paternal Caregivers For Youth Who Commit Sexual Offenses, Miranda Hope Sitney

Dissertations and Theses

This dissertation presents three manuscripts exploring the impact of caregivers, particularly male caregivers, on the development of juvenile sexual offending behavior. The first manuscript investigated the role of disrupted caregiving for juvenile sexual offenders compared to non-offending juveniles and youth who committed non-sexual crimes. The results indicated that juvenile sexual offenders have particularly poor relationships with their primary caregivers, especially if their primary caregiver was male. The second manuscript is a systematic literature review that explored the pathways through which male caregivers may influence the sexually aggressive behavior of their sons. A total of thirty-four articles describing three pathways (i.e., …

Inclusion For Speech-Language Pathology Minority Graduate Students, Teresa Michelle Roberts

Dissertations and Theses

Speech-language pathologists provide assessment and intervention for communication, cognition, and swallowing disorders for individuals across the lifespan in educational, medical, and private practice settings. The demographics of professionals in the field do not reflect those of the general public in regard to race and ethnicity, gender, socioeconomic status, LGBTQ+, and disability. Lack of representation of minorities limits research, policy, and services designed to serve diverse populations. Although initiatives have sought to address lack of diversity of speech-language pathologists, limited research on the graduate training experience for minority students is available. Since a master's degree is required to become a speech-language …

Home Resources Supporting Workplace Resources: An Investigation Of Moderated Intervention Effects From The Study For Employment Retention Of Veterans (Serve), Sarah Nielsen Haverly

Dissertations and Theses

Social support directly impacts psychological outcomes both within the home and work domains. Hammer and colleagues suggest that social support at work from supervisors is related to a number of positive workplace outcomes. Kossek et al. elaborated that social support from supervisors is additionally effective when it is tailored to the unique needs of workers (i.e., role demands). The Veteran Supportive Supervisor Training (VSST) educates supervisors how to better support former service-members employed within the civilian workplace. Additional sources of social support are also key to positive outcomes for workers. Research shows that support from a partner or spouse can …

Investigation Of Prussian Blue Analogues As Cathode Materials For Next Generation Batteries, Neal Walters Kuperman

Dissertations and Theses

Since the beginning of the industrial revolution, the average global temperature has risen about 1 °C due increases in anthropogenic greenhouse gases emitted into the atmosphere. Of all human produced greenhouse gases, carbon dioxide is the most prevalent, with the production of electricity from fossil fuels being the major contributor.

Solar and wind power are promising net zero emission energy sources but only accounted for ~5% of global electricity generation in 2016. The most significant hurdle hindering their widespread adoption is the intermittent nature of the electricity generation. To overcome this limitation, significant resources need to be put into the …

Contextualizing Educational Disparities And The Evaluation Of Teacher Quality, Dara Shifrer

Sociology Faculty Publications and Presentations

Value added scores, statistical estimates of teacher quality, are representative of neoliberal logic. The higher average scores of teachers of socially advantaged students raise concerns that scores are inaccurate and unfair, and propagate decontextualized neoliberal understandings of the nature of learning and teachers’ work. This study uses longitudinal data from roughly 4,500 teachers in a large urban district between 2007–08 through 2012–13 to follow individual teachers as they switch into schools of different “performance levels” over time. Fixed-intercept models tracking individual teachers between 2007–08 and 2012–13 showed scores increased for teachers who switched into high-performing schools and decreased for teachers …
