Introducing "Visual Bibliographies" As A Novel Tool For Communicating Complexity: A Knowledge Translation Case Study From Aboriginal And Torres Strait Islander Primary Health Care Research, Kathleen P. Conte, Alison Laycock, Jodie Bailie, Veronica Matthews, Ross Bailie

Homelessness Research & Action Collaborative Publications and Presentations

Background

Effective knowledge translation ensures health care research has desired impacts – this is particularly important for Indigenous communities who have historically not benefited from research about and on them. Yet much knowledge translation in Indigenous contexts continues without community partnerships and disregards Indigenous values, languages and knowledge-sharing practices. Visual approaches can be engaging knowledge translation strategies that align with Indigenous knowledge translation traditions and amplify Indigenous perspectives. In this paper, we introduce a new tool we have coined a “Visual Bibliography” for knowledge generation and translation, developed within a large-scale, participatory research collaboration in Aboriginal and Torres Strait Islander …

The Gut Microbiota Shapes The Human And Murine Breath Volatilome, Ariel J. Hernandez-Leyva, Amalia Z. Berna, Maggie H. Bui, Yang Liu, Anne L. Rosen, Michael A. Lint, Samantha A. Whiteside, Natalia Jaeger, Nikhilesh Joardar, Wentai Luo, Multiple Additional Authors

Chemistry Faculty Publications and Presentations

The gut microbiota is crucial to health, yet implementation of microbiota-based therapeutics is limited by the lack of rapid diagnostics. We hypothesize that breath contains gut microbe-derived volatile organic compounds (VOCs) reflecting microbiota composition and metabolism. In healthy children, we found that breath VOC composition (or volatilome), assessed by gas chromatography-mass spectrometry, correlates with gut microbiome composition and function. By capturing exhaled breath from human-stool-colonized and monocolonized gnotobiotic mice, we profiled breath VOCs and discovered that murine breath is also significantly influenced by the gut microbiome. VOCs from cultured gut microbes were identified in vivo in monocolonized gnotobiotic colonized mice. …

Microbial Communities And Biogeochemistry Of A Melting Rocky Mountain Glacier, Pacifica Sommers, Elizabeth Traver, Alison Orthel, Andrew G. Fountain, Jacki Klancher, Steven K. Schmidt

Geology Faculty Publications and Presentations

Mountain glaciers are disappearing rapidly, and with their disappearance, we may be losing unstudied biodiversity and genetic resources. A variety of habitats for microorganisms exist on glaciers, especially within pockets of supraglacial sediments (cryoconite) that support high levels of biological activity and diversity. We used biogeochemical approaches, high-throughput DNA sequencing, and microscopy to describe the biogeochemistry and microbial communities of supraglacial sediments on the Dinwoody Glacier in the Wind River Range, Wyoming. Carbon (C) and nitrogen (N) concentrations were high, and C:N ratios were close to the Redfield ratio indicating active nutrient cycling. We found unique microbial communities in sediments …

Global Deep-Sea Hydrothermal Deposit Metagenomes And Metagenome-Assembled Genomes Over Time And Space, Emily St John, Anna-Louise Reysenbach

Center for Life in Extreme Environments Publications

Actively venting high temperature deep-sea hydrothermal vent deposits along tectonic spreading centers and in backarc basins harbor a rich diversity of thermophilic Bacteria and Archaea, many of which have no representatives in cultivation nor any genomic representation in databases. Here, in order to produce a global-scale time series metagenomic resource for studying the microbial functional and genomic diversity in these high temperature ecosystems, we obtained 70 metagenomes from collections across spatial and temporal gradients from 21 different vent fields spanning 16 years (1993-2009). The dataset (Deep-Sea Hydrothermal Vent dataset (DSV70)) includes 3.56 Tbp of raw DNA sequence reads, that have …

The Explored Experiences Of Latino Families In The Neonatal Intensive Care Unit, Devlynne S. Ondusko, Veronica I. Underwood Carrasco, Astrid Platteau, Susanne Klawetter, Roberta Suzette Hunte, Emily Hawkins Carter, Morinne Osborne, Jaime W. Peterson

School of Social Work Faculty Publications and Presentations

While many families experience multiple etiologies of stress during a neonatal intensive care unit (NICU) admission, unique stressors arise for certain groups that are at higher risk for disparities in infant outcomes, including Latino families. The objective of this study was to explore the experiences of Latino families regarding support received in the NICU while their infant was hospitalized to identify ways to enhance the quality of care.

Cognitive And Economic Development, John Luke Gallup

Economics Faculty Publications and Presentations

A burgeoning literature has found that early childhood health conditions of individuals have large causal effects on their cognitive development, education and earnings. How much does early cognitive development contribute to the national economy? Although researchers have long studied the role of worker health for economic growth, they have not assessed the role of early cognitive development.

Cognitive ability is the foundation of human capital, affecting both educational attainment and economic growth. The risk factors for poor cognitive development are very high in many countries. Each risk factor also causes child mortality, making child survival a viable proxy for good …

Citizen Engagement In Budget Simulation: Examining The Effectiveness Of Balancing Act Modules In Aligning Public Priorities And Allocation Choices, Frankline Muthomi

Public Administration Faculty Publications and Presentations

This study investigates the extent to which individuals exhibit consistency in their preferences during sequential budget simulation exercises, as well as the factors that shape these preferences. Grounded in behavioral and citizen participation frameworks, the analysis demonstrates that the simultaneous use of priority-setting and budget-balancing modules encourages participants to allocate resources in ways that reflect their previously articulated priorities. While instances of inconsistency remain common, preference consistency is associated with participants’ sustained support for their favored programs, their commitment to ensuring adequate resource allocation, and, to some extent, their willingness to finance these programs. The findings suggest that the integrated …

Pláticas Of Latinas In Educational Leadership: Stories Of Identity, Resilience, And Transformation, Vanessa Davalos

Educational Leadership Professional Doctorate Dissertations

Despite federal and state equity laws that prohibit discrimination based on sex and national origin, women remain significantly underrepresented in K–12 educational leadership, with Latina leaders experiencing even greater disparities. While the number of Hispanic students in public schools continues to grow, the representation of Latina leaders has not kept pace, creating a critical gap between those leading schools and the communities they serve.

The purpose of this qualitative phenomenological study is to provide insight into the lived experiences of Latina educational leaders in order to deepen understanding of how identity, role, and leadership intersect (Hernandez & Murakami, 2016). Centering …

Using Maximum Entropy (Maxent) Tool In Arcgis Pro For Species Distribution Modelling Of Pseudoscorpions In The Pacific Northwest, Elliot Toshihiro Cochran

Masters in GIS Practicum Reports

The use of Geographic Information Systems (GIS) to create Species Distribution Models (SDMs) is rising among many scientific disciplines. Many professionals who were not originally focused on GIS are increasingly becoming more invested in this technology. SDMs are widely used to estimate species’ potential geographic distributions and to evaluate the environmental factors that constrain their ranges. The presence-only maximum entropy (MaxEnt) algorithm implemented in the MaxEnt tool in ArcGIS Pro was used in this project to model habitat suitability for two species of pseudoscorpions, M. pacificus and an undescribed species, in Oregon and Washington. Presence points (of specimen sample locations) …

Artemisia Gentileschi's Last Susanna, Shelby A. Morgan

Anthós

Artemisia Gentileschi (1593-1645), a celebrated 17th century Baroque painter, depicted the biblical story of Susanna and the Elders six times in her long career of approximately 44 years (1610-1654). The first five were all painted and arranged vertically with Susanna's nude body exposed. Whereas her last Susanna (1652) and consequently her final known painting was painted horizontally with fabric covering, yet skimming Susanna’s nude body underneath. My research question is: Why at such a late stage in her career did Artemisia decide to reconfigure the composition of Susanna and the Elders and transform the representation of Susanna’s body through this …

Political Elections In The New Wave Of Media: The Celebrification Of The Presidency, Camille B. Moore

Anthós

This article examines the impact of social media on journalism leading up to the 2024 United States presidential election and how expectations of candidates have changed. By exploring the degradation of discourse in news and how polarization and cognitive biases have intensified with the widespread adoption of social media, previous candidate conventions have begun to crumble. This has, and will continue to have, a large impact on voting and democracy in America, as scholars have noted since the beginning of the 2000’s, in examining a shift in news preferences as pop culture gains influence. This work further examines recent scholarship …

Personhood Amidst Process, Bennett B. Gilbert

History Faculty Publications and Presentations

Both process philosophy and key forms of philosophical personalism aim to harmonize the flux of reality, especially of organisms, with cosmic values and human meaningfulness. This is because both must face our mortality. This paper makes four suggestions for considering further the connection between these two approaches. First, that process philosophy can supply for personalism a thoroughly reasoned ground for nonreducible complexity. Second, that process thought borrows from personhood its model for cosmic creativity. Third, that both approaches share strong notions of the interdependence of all parts of a relational universe. And fourth, that they differ in respect of moral …

Erasing The Artist, Policing The City: Michael Stewart And New York’S War On Graffiti, Vladislav Kirilov

Anthós

The 1983 death of Michael Stewart, a young Black graffiti artist, exposes the violent logic at the center of New York City’s War on Graffiti. Under Mayor Ed Koch and the rise of broken windows policing, graffiti was framed as a racialized symbol of disorder used to justify intensified control of public space. Rather than becoming political in this moment, graffiti is understood here as an already politicized form of expression shaped by racial and spatial inequality. The article examines how Stewart’s killing made police violence visible, provoking responses from artists, activists, and graffiti writers while revealing the human costs …

The Public Relations Of Microtonal Music Through The Eyes And Ears Of Microtonalists, Tristan B. Young

Anthós

In this article, I attempted to answer the question of how microtonal musicians and music theorists view the general public's perception of microtonal music. To do this, I had three one-on-one interviews and one focus group with microtonal musicians, which were all audio recorded with consent from the participants. Patterns that emerged from their responses included blaming corporate and academic establishments for their conservatism in music theory, mentioning the different possible definitions one may make for microtonality based on geographic culture and so on, and bringing up the idea that people think that microtonality is less diverse than it actually …

A Guide To Human Ecology Mapping: An Approach For Understanding Human-Environment Connections, Thien-Kim Bui, Rebecca J. Mclain, David Banis, Lee Cerveny

Occasional Papers in Geography

Occasional Papers in Geography Publication No. 9

Places matter to people, and maps can help people and communities share why places matter. Over the past 30 years, public participation GIS (PPGIS) and other forms of human ecology mapping (HEM) have become important ways for agencies, non-governmental organizations, environmental and community advocacy groups, university researchers, and others to learn about or advocate for what matters to people about landscapes they visit, use, or love.

HEM is a method for mapping human-environment interactions and connections. This manual is intended for the planner or practitioner who is interested in using HEM to strengthen …

Home Rule, Dillon’S Rule, And The Legal Shape Of Local Governance, Bradon J. Rothschild

National Policy Consensus Center Publications

Public policy in common law democracies such as the United States is dictated by many factors, which you might call streams or strands. While on the one hand the vox populi may insist on a certain action, governing coalitions of political leaders may deign another direction, or policy researchers may conclude a third option is better yet. All such options, however, are constrained by the legal parameters of governance as defined by constitutional, statutory, and case (jurisprudence, or stare decisis) law. Where these streams meet, public policy actions which are popularly supported, politically advantageous, technically effective, and (importantly) legal may …

Heat Misers, Snow Misers, And Cognitive Misers: The 'Nukewarm' Perceptions Of Nuclear Power, Tyler Williams

Dissertations and Theses

Rising energy demand in the United States necessitates alternatives to fossil fuels, yet renewable energy sources alone are insufficient to meet this demand. Nuclear power presents a promising option but faces persistent public hesitancy. This study examines how heuristic-based biases relate to American's risk-benefit perceptions towards nuclear power. Guided by the heuristic-systematic model. Results indicate that competence and affect are related to risk-benefit perceptions, and naturalness shows no relationship with risk perceptions but does correlate with benefit perceptions. Implications highlight the importance of affect-driven communication strategies for nuclear communicators, while also underscoring the need for participatory approaches that foster trust …

Into Me See: Visibility, Recognition, And The Need To Be Seen In Kazuo Ishiguro’S Never Let Me Go, Vicki L. Wine Carney

Anthós

While critical scholarship on Kazuo Ishiguro’s Never Let Me Go often emphasizes bioethics, transhumanism, and the commodification of life, this lens overlooks the novel’s profound engagement with the psychological necessity of visibility. This paper argues that the tragedy of the clones is fundamentally a crisis of recognition, where invisibility is not incidental but structurally produced to facilitate exploitation. Drawing on Caroline Levine’s concept of the "Form of Utility" and Axel Honneth’s Theory of Recognition, this study examines how systemic indoctrination and objectification deny the clones their innate humanity to soothe the conscience of the "normals." Furthermore, it analyzes the characters’ …

Drag’S Impact On Drag Lives, José L. Oropeza Iii

Drag’s Impact On Drag Lives

In light of recent political developments where Drag and Trans identities are being punished, why do people still participate in Drag? If there are repercussion to face for being a Drag Queen, then surely it must affect their lives for the better for them to continue the practice.

Through an autoethnographic approach to researching the Portland, OR Drag community, I collected transcripts of conversations with local Queens, took notes of community interactions, and put myself in Drag for the first time as a Queer man to better understand the Drag community and why they Drag. …

Creating Community Through Walking The Talk For Dementia, Kate Irving, Fernando Aguzzoli Peres, Walter D. Dawson, Jonathan Adrián Zegarra-Valdivia, Lingani Mbakile-Mahlanza, Iracema Leroi, Sherril B. Gelmon

Institute on Aging Publications

Objectives

Creating community is not only therapeutic—it has been described as essential. This study explores a process of community-building among people with lived and professional experience in the dementia field, during Walking the Talk for Dementia (WTD), a week-long, immersive event on the Camino de Santiago in Spain. Absence of community can lead to fragmented support for both people living with dementia and their care partners and for those working in the field. Achieving a sense of community, however, can be complex.

Methods

A qualitative evaluation was conducted with 79 participants from 27 countries, incorporating pre-, during and post-event reflections. …

The Distribution Of A-Numbers Of Hyperelliptic Curves In Characteristic Three, Derek Garton, Jeffrey Lin Thunder, Colin Weir

Mathematics and Statistics Faculty Publications and Presentations

In this paper we present a new approach to counting the proportion of hyperelliptic curves of genus g defined over a finite field Fq with a given a-number. In characteristic three this method gives exact probabilities for curves of the form Y 2 = f(X) with f(X) ∈ Fq[X] monic and cubefree, probabilities that match the data presented by Cais et al. in previous work. These results are sufficient to derive precise estimates (in terms of q) for these probabilities when restricting to squarefree f. As a consequence, for positive integers a and g we show that the nonempty strata …

Density Dependence During Evolutionary Rescue Increases Extinction Risk But Does Not Prevent Adaptation, Laure Olazcuaga, Brett A. Melbourne, Scott W. Nordstrom, Ruth A. Hufbauer

Publications, Reports and Presentations

Evolutionary rescue allows populations to adapt and persist despite severe environmental change. While well studied under density-independent conditions, the role of density dependence, including competition, remains unclear. Theoretical models offer conflicting predictions, with density dependence either increasing extinction risk or enhancing adaptation. We empirically tested how density dependence influences evolutionary rescue by exposing experimental populations to a stressful environment for six generations under density-dependent or independent conditions, with populations where either evolution was possible or was prevented by replacing individuals each generation. Density dependence suppressed population size and increased extinction risk, whereas density independence enabled rapid growth, especially in genetically …

The Hope Industrial Complex: Resisting Manufactured And False Hope With Critical Hope In Peace Education, Thailand's Refugee Context, Staci B. Martin, Hayso Thako, Rey Ty, Sudarat Tuntivivat, Rattanak Ly

School of Social Work Faculty Publications and Presentations

Our Point of Departure (POD) argues that the type of hope fostered within the Karen refugee community in Thailand – manufactured, false, or critical – shapes the impact of peace-building and higher education efforts. Through a dialogue among a Karen scholar, his supervisor, and a migration researcher, we demonstrate that manufactured hope, often driven by external aid, sustains dependency and overlooks core conflicts. In contrast, false hope arises from the gap between student desires and institutional barriers, leading to unmet expectations. We aim to show that by applying critical hope, the pedagogical approach enables the Karen community to enhance its …
