Best Practices For The Naming Of Species, Luis A. Ruedas, Ryan W. Norris, Robert M. Timm

Biology Faculty Publications and Presentations

The process of describing a species has evolved considerably since the modern age of taxonomy was initiated with the publication of the 10th edition of Linnaeus’ Systema Naturæ in 1758. Nevertheless, the basic unit of the taxonomic framework remains the species group (species and subspecies). As a result, it is incumbent upon individuals undertaking species-group descriptions to strive for the highest standards, just as it is for reviewers and editors to hold authors to those same standards. The clear and mounting biodiversity crisis, the increasing proliferation of journals, the multiplication of journals publishing only in electronic format, the decline in …

Faint Glimmers: Redrawing The Housewife In Yamada Murasaki's Talk To My Back, Ceres Lovelace

Dissertations and Theses

Yamada Murasaki's seminal manga collection Talk to My Back, originally titled Shinkirari, tells a story of a woman's gradual journey toward agency within the constraints of a nuclear patriarchal family. Set within the everyday suburban life of Chiharu in 1980s Japan, Yamada uses subtle visual cues and restrained narrative techniques to illustrate her protagonist's struggles and quiet breakthroughs as she questions her identity and renegotiates her role as a housewife and mother.

By exploring the often-overlooked inner world of a housewife, Yamada scrutinizes traditional gender roles and reveals the burden and psychological toll of the emotional labor imposed on …

Foreign Funding Of U.S. Higher Education Relates To Sanctioning Of Scholars And Antisemitism, Michael Bass, Alexander Reid Ross, Ben Wolfson, Joel Finkelstein, Sonia Yanovsky, Danit Finkelstein, Sean T. Stevens, Nathan Honeycutt, Pamela Paresky, Ayal Feinberg, Multiple Additional Authors

Geography Faculty Publications and Presentations

We examined relations between foreign funding of U.S. colleges and universities and campus political developments. Seven studies investigated associations between foreign funding and campus liberal democratic norms, specifically, deterioration of free speech and academic freedom, and presence of antisemitism. Study I found that 349 colleges and universities received a total of almost $18 billion from foreign sources between 2014 and 2019. Study II examined relationships of foreign funding to campus deplatforming of speakers and punitive actions for speech protected by academic freedom. Main results were: 1. overall foreign funding was not strongly related to campus speech outcomes; 2. higher levels …

Techniques For Modeling Ocean Soundscapes: Detailed Description For Wind Contributionsa, Martin Siderius, Michael A. Ainslie, John Gebbie, Alexandra Schäfke, N Ross Chapman, Bruce Martin, Kay L. Gemba

Electrical and Computer Engineering Faculty Publications and Presentations

Wind over the ocean creates breaking waves that generate air-filled bubbles, which radiate underwater sound. This wind-generated sound is a significant component of the ocean soundscape, and models are essential for understanding and predicting its impact. Models for predicting sound pressure level (SPL) from wind have been studied for many years. However, the terminology and definitions behind modeling approaches have not been unified, and ambiguity has led to differences in predicted SPL. The 2022 Ambient Sound Modeling Workshop was organized to compare ambient sound modeling approaches from different researchers. The main goal of the workshop was to quantify differences in …

How Management Disclosure And Auditor Disclosure Affect Auditor Liability: The Case Of The Going Concern Financial Accounting Standard, Joel Owens, K. Kelli Saunders, Samantha Schachner, Todd A. Thornock

Business Faculty Publications and Presentations

A current FASB standard requires management to assess the ability of the entity to continue as a going concern (GC) and disclose any substantial doubt about such. Using contextualized experiments wherein the auditor does not issue a GC opinion for an entity that subsequently fails, we study the effects of management disclosure, increased management disclosure responsibility, and auditor disclosure on auditor blame, a proxy for auditor liability. Consistent with predictions based on the Culpable Control Model, we find (1) management disclosure of substantial doubt increases auditor liability; (2) when management has not disclosed substantial doubt, auditor liability is greater under …

The Crime Of Luring A Minor For Contact Sexual Abuse: Exploration Of Demographic Patterns & Criminal Records Of Convicted Offenders., Bridget Diamond-Welch, Anna E. Kosloski, Christopher P. Carey, Molly Mcdade

Criminology and Criminal Justice Faculty Publications and Presentations

Background

Child sexual abuse (CSA) is a significant public health problem, with a small but important subset of crimes committed by strangers, often facilitated through luring. Understanding the characteristics of individuals who engage in luring is essential for developing effective prevention and intervention strategies.

Objective

This study aimed to analyze the demographic characteristics and criminal histories of individuals convicted of luring a minor and to examine the types of crimes committed before and after conviction.

Participants and setting

The study included all individuals (N = 115) convicted of “luring a minor” between 2011 and 2021 in one county in …

Bipolar Ionization Did Not Reduce Airborne Bacteria In A Lecture Hall, David A. Kormos, Nishit J. Shetty, Elliott T. Gall, Aaron J. Prussin, Amy Pruden, Linsey C. Marr

Mechanical and Materials Engineering Faculty Publications and Presentations

Ionization treatment of indoor air has attracted attention for its potential to inactivate airborne pathogens and reduce disease transmission, yet its real-world effectiveness remains unverified. We evaluated the impact of an in-duct, bipolar ionization system on airborne particles, including culturable bacteria, in a lecture hall. The ionizer was off with variable fan speed for 1 week, on with variable fan speed for a second week, and on with high and constant fan speed for a third week. We measured ion concentrations and aerosol particle concentrations, and we collected bioaerosol samples for analysis of 16S rRNA gene copies representing total bacteria …

Effects Of Spontaneous Curvature On Interfacial Adsorption And Collapse Of Phospholipid Monolayers, Bret A. Brandner, Shankar B. Rananavare, Stephen B. Hall

Chemistry Faculty Publications and Presentations

To function effectively, pulmonary surfactant must adsorb rapidly to the alveolar air/water interface but avoid collapse from the surface when compressed to high interfacial densities. Prior studies show that phospholipids in the cylindrical monolayers of the inverse hexagonal (HII) phase adsorb quickly. The monolayers have negative curvature, defined by the concave shape of the hydrophilic face. Formation of the HII structures, however, involves significant disruption of chain-packing. Samples with significant spontaneous curvature, formed in the absence of applied force, may nonetheless have lamellar structures that optimize chain-packing. The experiments here tested whether planar lamellar bilayers formed by phospholipids with negative …

Exploring Determinants Of Transit Recovery After The Covid-19 Pandemic, Udit Khandelwal

Dissertations and Theses

The COVID-19 pandemic significantly disrupted public transit systems across the US, resulting in substantial declines in ridership and revenue. At the same time, ridership has increased to different levels in cities. This thesis explores the determinants of transit recovery in American cities post-pandemic. It analyzes data from the National Transit Database (NTD) and employs a two-stage least squares (2SLS) regression model first laid out by Taylor et al. (2008) for data from 2000. Similar to the results of that paper, the thesis finds strong correlation between transit ridership and variables for transit supply and urban and demographic characteristics for 2019 …

Book Review: Calling Family: Digital Technologies and the Making of Transnational Care Collectives

Dcai: The 4th International Workshop On Data-Centric Ai, Yanjie Fu, Kunpeng Liu, Dongjie Wang

Computer Science Faculty Publications and Presentations

Machine learning traditionally emphasizes developing models for given datasets, but real-world data is often messy, making model improvement insufficient for enhancing performance. Data-Centric AI (DCAI) is an emerging field that systematically improves datasets, leading to significant practical ML advancements. While experienced data scientists have manually refined datasets through trial-and-error and intuition, DCAI approaches data enhancement as a systematic engineering discipline. DCAI represents a shift from focusing on models to the underlying data used for training and evaluation. Despite the dominance of common model architectures and predictable scaling rules, building and using datasets remain labor-intensive and costly, lacking infrastructure and best …

Characterizing The Influence Of Metabolism On Steady State Water Exchange In Yeast As A Potential Mri Diagnostic Biomarker, Samantha Mumford

Dissertations and Theses

Under conditions of ionic equilibrium with the environment a cell maintains a constant volume yet rapidly exchanges water molecules with the extracellular space. The rate constant for steady state water efflux, k_io, can be measured using contrast enhanced magnetic resonance (CE-MR). The active water cycling (AWC) hypothesis is puts forward that k_io is primarily influenced by cellular ATP levels and H⁺ ATPase activity at the cell membrane. Due to the correlation between k_io and ATP levels, k_io is thought to be a probable MRI biomarker for metabolic diseases such as cancer. Yet, the molecular …

Promoting Equity In Culturally Diverse Schools: A Literature Review Of Third Space Pedagogy, Sarah E. Harrison, Heidi Curtis

Northwest Journal of Teacher Education

The increasingly culturally diverse settings present within today’s P-12 schools necessitate improved pedagogical practices to develop more culturally inclusive and equitable learning environments. Third-space pedagogical practices demonstrate potential as an approach for increasing educational equity by promoting cultural hybridity among diverse students and stakeholders through negotiated sociocultural perspectives and interactions. This literature review summarizes recent scholarship surrounding third-space pedagogy, including discussions of how educators can foster third-space relationships and design third-space learning opportunities in diverse educational settings. In addition, lessons from COVID-19 third-space learning opportunities are discussed as a model for re-envisioning equitable instructional practices post-pandemic.

Education And Tolerance Of Homosexuality In Diverse Islamic Contexts, Camila Swift

Dissertations and Theses

This study examines the relationship between educational attainment and moral tolerance of homosexuality among Muslims in Algeria, Malaysia, Pakistan, and Turkey. Utilizing human development theory to understand how educational attainment affects social values, the analysis draws on data from over 5,000 respondents from the Pew Research Center's "World's Muslims" dataset, which includes responses from a nationally representative sample of Muslims in these four countries. Logistic regression models and predicted probabilities are used to explore how educational attainment relates to moral tolerance of homosexuality, adjusting estimates for various alternate explanations through the use of control variables. The findings reveal that the …

Online Crime Reporting: A New Threat To Police Legitimacy?, Kris Henning, Kimberly Kahn, Kathryn Wuschke, Christian Peterson, Stephen Yakots

Criminology and Criminal Justice Faculty Publications and Presentations

Police are more likely to be perceived as legitimate when officers are procedurally just during interactions with the public (i.e. impartial, transparent, fair and respectful). Efforts to reinforce these skills have largely focused on contacts initiated by officers. Less attention has been paid to interactions with crime victims. Moreover, in recent years many police departments have sought to increase efficiency by directing victims to report online, rather than communicating directly with an officer. Very little is known about how victims experience online reporting systems. This study surveyed 1,198 property crime victims who used a large US police department’s online reporting …

On Localization Of Eigenfunctions Of The Magnetic Laplacian, Jeffrey S. Ovall, Hadrian Quan, Robyn Reid, Stefan Steinerberger

Mathematics and Statistics Faculty Publications and Presentations

Let Ω ⊂ ℝd and consider the magnetic Laplace operator given by H(A) = (–i∇ – A(x))2, where A : Ω → ℝd, subject to Dirichlet boundary conditions. For certain vector fields A, this operator can have eigenfunctions, H(A)ψ = λψ, that are highly localized in a small region of Ω. The main goal of this paper is to show that if |ψ| assumes its maximum at x0 ∈ Ω, then A behaves 'almost' like a conservative vector field in a -neighborhood of x0 in a precise sense. In particular, we expect localization in regions where |curl A| is small. …

A Magical Symbiosis: The Advent Of Witchcraft In The Age Of Social Technology, James Dryden

University Honors Theses

This paper investigates the relationship between social media and witchcraft practitioners in online communities. After providing a landscape of how other researchers have studied similar phenomenon, interviews with anonymous witches who utilize online platforms such as TikTok and Instagram were conducted by the author. Using these testimonies in conjunction with the research of others, the author identifies trends and similar stories between American witches regarding Wicca, the commodification of the craft, and how witchcraft practice continues in the modern day.

Holistic Methodologies For Fusing The Material And The Ideological: Tracing The Sociotechnical Imaginaries That Enable The World’S Fastest Supercomputer, Sarah Read, Jordan Firth

English Faculty Publications and Presentations

When the Aurora supercomputer launches at Argonne National Laboratory it will operate at the exascale and be one of the fastest supercomputers in the world. We have been invited by Argonne to do field work to understand both the day-to-day processes that maintain supercomputing (e.g. user documentation, government reporting, user testing) and the sociotechnical national imaginaries [11], –in particular the increasingly tense global competition between the US and China in the supercomputing race–that shaped the development of Aurora. This article proposes our work-in-progress methodological approach that accounts for both higher-level imaginaries and the everyday practices of supercomputing. We also describe …

OHSU-PSU School of Public Health Faculty Publications and Presentations

Community science has increased in popularity in communities where residents hope to investigate the relationship between environmental issues and personal health. This study partnered with neighborhoods in the most polluted residential zip code in the US to conduct community science air quality monitoring. We conducted 60 semi-structured interviews after two monitoring deployments to understand participants’ subjective experiences of pollution exposure, their engagement with low-cost air quality monitors, and their data interpretation. We utilize the environmental health concept ‘exposure experience’ to analyze how participants use personal monitors, understand their data, and reinterpret their pollution exposure as a result. We further explore …

Far-Right Monologues And Extreme Identity, Benjamin Alexander Thigpen

Dissertations and Theses

My thesis is focused on the American far-right, by way of two sperate case studies, one centered on a contemporary movement (the manosphere) and one that has fallen from prominence (racist skinheads). Grounded in primary source analysis, my thesis builds off of the work of social movement theorists such as Sidney Tarrow, scholars of American politics like Richard Hofstadter, and emergent theories of social identity as laid out by Judith Butler and others. Through my analysis, I develop two theoretical arguments: first, that there are two distinct categories amongst far-right narratives (which I term offensive and defensive); and second, that …

The current paper utilizes an ecological level of analysis framework to review and critique the literature surrounding predictors, correlates, and antecedents of Latinos' intimate partner violence (IPV) behaviors. More specifically, the ecological levels of analysis framework was employed to demonstrate how Latino males' IPV perpetration is being understood and studied. A total of n = 34 peer-reviewed articles were reviewed and critiqued. Findings indicated that most IPV research is being conducted at and comprehended from the individual (n = 33; 97%) and microsystem/small group (n = 24; 71%) levels of analysis, while linkages to organizational, locality, and institutional levels of …

Fostering Resilience: Community Radio And Disaster Communication In Odisha, India, Manas Kumar Kanjilal, Kanchan K. Malik, Priya Kapoor

International & Global Studies Faculty Publications and Presentations

Local voices carry tremendous weight during natural disasters, yet the possibilities for employing participatory communicative practices for disaster management in India have not been fully explored. Effective community-centred disaster communication garners participation in disaster management processes that reduce vulnerabilities. This paper examines how various community-based organisations used community radio to enhance community engagement and the effectiveness of the disaster management processes in the eastern Indian state of Odisha. The research relies upon case studies of disaster communication practices of two community radio stations during the ‘very severe cyclonic storm’ Yaas, which made landfall in Odisha. It describes the conceptual shift …

Reporting Gunshots: Prevalence, Correlates, And Obstacles To Calling The Police, Kris Henning, Joshua Carmony, Somalia Johnson Calloway, Christian Peterson

Criminology and Criminal Justice Faculty Publications and Presentations

Accurately documenting where and when firearms are discharged is a critical first step in gun violence prevention. Many cities rely on police calls for service as their primary source for this information. Recent studies find, however, that citizens underreport gunshots. This has led some communities to invest in gunshot detection technology (GDT) as an alternative data source. GDT remains an expensive and often controversial solution with limited evidence for long-term benefits. This underscores the need for additional research on third-party reporting of gunshots. The current study, conducted in Portland Oregon, surveyed 1,240 residents in 23 neighborhoods with above-average firearm discharges. …

The Nexus Of Resistance And Neoliberalism In Social Work And Social Welfare: A Scoping Review, Kevin Cherry, Sandra Leotti

School of Social Work Faculty Publications and Presentations

This study intervenes in a growing scholarly dialogue about neoliberalism in social work and social welfare by addressing the undertheorized concept of resistance. We conduct a scoping review of 54 articles published from 2008–2023 to answer two questions: how is resistance discussed in relation to neoliberalism, and what are the practice elements of resistance? Findings highlight resistance as a diverse phenomenon enacted in relation to context-specific manifestations of neoliberalism. A range of actors engage in resistance, including individual practitioners, social service organizations and collective action entities, among others. Resistance occurs across all scales of practice and takes many forms, from …

Climate Hazards And Human Migration: Literature Review, Anna Ivanova, Deepti Singh, Pronoy Rai, Claire Richards, Hugo Vasconcelos, Michael Goldsby

International & Global Studies Faculty Publications and Presentations

Human populations are migrating as a result of climate change. We conducted a systematic literature review examining the relationship between several climate hazards and migration flows. We reviewed 58 empirical studies between 2010 and 2023 that examined current and future migration related to acute and long-term climate hazards. The results indicate that the relationship between climate hazards and migration is diverse and depends on a range of socio-economic factors. Droughts and rising temperatures have a major impact on both international and domestic migration. Our review also reveals that multiple climate hazards collectively tend to intensify domestic migration toward urban areas, …

Minimal Separating Sets In Surfaces, Christopher Nelson Aagaard

Dissertations and Theses

Given a connected topolgical space X, we say that L ⊆ X is a minimal separating set if removing L from X gives a disconnected surface, butremoving any proper subset of L leaves the surface connected. We classify which embeddings of topological graphs are minimal separating in an orientable surface X with genus g, and construct a computer program to compute the number of such embeddings, and the number of topological graphs which admit such an embedding for g ≤ 5.
