Thermal Regimes Of Beaver Impacted Stream Reaches In The Tualatin River Basin, Miles Mayer

Dissertations and Theses

Climate change and urbanization are expected to cause major changes to hydrologic regimes over the Pacific Northwest Region. The Tualatin River Basin, an area of the Pacific Northwest just west of Portland, OR has been subjected to considerable water-quality issues, including stream temperature. As ecosystem engineers, beavers have the potential to mitigate stream degradation and, consequently, there is increasing interest in beaver-related restoration. However, different conclusions have been found on beaver dam impacts to stream thermal regimes. These differences have been attributed to geographical differences in study location and variability in methods and investigated spatiotemporal scales. We investigated summer thermal …

A Second Homotopy Group For Digital Images, Gregory Lupton, Oleg R. Musin, Nicholas A. Scoville, P. Christopher Staecker, Jonathan Treviño-Marroquín

School of Mathematical & Statistical Sciences Faculty Publications

We define a second (higher) homotopy group for digital images. Namely, we construct a functor from digital images to abelian groups, which closely resembles the ordinary second homotopy group from algebraic topology. We illustrate that our approach can be effective by computing this (digital) second homotopy group for a digital 2-sphere.

Spatial Optimism And Cross-Over Effects In The Perceptions Of Interconnected Wildfire, Flood, And Mudslide Hazards, Douglas Houston, Omar Pérez Figueroa, Ariane Jong-Levinger, Brett F. Sanders

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Communities near the wildland urban interface (WUI) are exposed to a mix of three interconnected hazards (wildfire, flood, and mudslide), and understanding multi-hazard perceptions is critically important for emergency preparation and hazard mitigation—particularly given the WUI’s rapid expansion and intensifying environmental hazards. Based on a survey of residents living near recent burn scars in Southern California, we document cross-over effects in hazard perceptions, where resident experience with one hazard was associated with greater hazard rankings for other hazards. Additionally, for all three hazards analyzed we document perceptions of increasing hazard levels with increasing spatial scales (home, near-home, neighborhood, and community), …

Faculty, Staff and Student Publications

Prostate cancer (PCa) is a multifactorial disease influenced by genetic, environmental, and immunological factors. Genetic polymorphisms in the interleukin-10 (IL-10) gene have been implicated in PCa susceptibility, development, and progression. This study aims to assess the contributions of three IL-10 promoter single nucleotide polymorphisms (SNPs), A-1082G (rs1800896), T-819C (rs3021097), and A-592C (rs1800872), to the risk of PCa in Taiwan. The three IL-10 genotypes were determined using PCR-RFLP methodology and were evaluated for their contributions to PCa risk among 218 PCa patients and 436 non-PCa controls. None of the three IL-10 SNPs were significantly associated with the risks of …

Faculty, Staff and Student Publications

Primary Ciliary Dyskinesia (PCD) is a rare genetic disorder characterized by alterations in motile cilia function. The diagnosis of PCD is challenging due to the lack of standardized methods in clinical practice. High-speed video microscopy analysis (HSVA) directly evaluates ciliary beat frequency (CBF) in PCD. Recently, open-source ciliary analysis software applications have shown promise in measuring CBF accurately. However, there is limited knowledge about the performance of different software applications, creating a gap in understanding their comparative effectiveness in measuring CBF in PCD. We compared two open-source software applications, CiliarMove (v219) and Cilialyzer (v1.2.1-b3098cb), against the manual count method. We …

Faculty, Staff and Students Publications

Background: Betulinic acid (BA) has been well investigated for its antiproliferative and mitochondrial pathway-mediated apoptosis-inducing effects on various cancers. However, its poor solubility and off-target activity have limited its utility in clinical trials. Additionally, the immune modulatory role of betulinic acid analogue in the tumor microenvironment (TME) is largely unknown. Here, we designed a potential nanotherapy for colorectal cancer (CRC) with a lead betulinic acid analogue, named as 2c, carrying a 1,2,3-triazole-moiety attached to BA through a linker, found more effective than BA for inhibiting CRC cell lines, and was chosen here for this investigation. Epithelial cell adhesion molecule (EpCAM) …

Fanfiction: When Copyright Violation Benefits Brands, Ethan Milne, Kirk Kristofferson, Miranda Goode

Proceedings from the Document Academy

We investigate fanfiction (i.e., original fiction adopting elements of pre-existing media), as a copyright-violating phenomenon and show it can benefit brands. Our work first identifies two benefits of fanfiction: 1) reading fanfiction increases purchase intent for brand content, 2) and fanfiction production rates can be used to generate more accurate estimates of next-week TV viewership. Next, we identify that brands can grow their fanfiction communities by waiving copyright protection, thus removing a barrier to publication faced by many fanfiction authors. We demonstrate these results using two real-world datasets representing billions of words of fanfiction content, and one lab study (N=600).

Archiving The Ephemeral In Digital Public Space: Using Speculative Design To Consider Collaborative Fan Play In The Metaverse, Naomi Jacobs

Proceedings from the Document Academy

Looking at fan activity through the lens of play, this paper considers the archiving opportunities and challenges posed by new technology for playful ephemeral fan co-creation in multiplatform digital contexts. These include technical concerns such as platform fragility and how to capture inherent liveness and temporality, but also ethical concerns such as sustainability, consent and content moderation.

To examine this, the paper takes fan-created alternate reality games (ARGs) as a particular example of such archiving challenges. It first describes a real example of such a game, ‘Blow the Man Down’ before introducing speculative design as a method to consider a …

Investigating Veterinarians' Interest In Mental Health, Loren C. Beggs, Jisook Park

Academic Leadership Journal in Student Research

Stress affects all individuals though individuals’ response to stressors can be different. When stress is not managed effectively, it can lead to severe physiological concerns as well as psychological damages such as depressive symptoms and even suicidal ideations. Veterinarians are known to have a higher depression level and suicide rate than the general population which could be attributed to higher occupational stress. The purpose of the current study is to investigate the mental health state of veterinarians and the relationship between psychological distress and pursuit of mental health resources. We also explored the relationship between psychological distress and perceived importance …

Who Lives Where: A Comprehensive Population Taxonomy Of Cities, Suburbs, Exurbs, And Rural Areas In The United States, Brian Edward Johnson, Jason Shifferd

The Geographical Bulletin

This paper answers the question: how many Americans live in cities, suburbs, exurbs, and rural areas in the United States? Previous works have examined only one or some of these settlement types instead of accounting for the entire country’s population, or have employed highly technical classifications uncommon in common parlance. T his paper develops a comprehensive classification scheme using vernacular settlement types, then organizes U.S. Census data into the taxonomy presented here. This research contributes to the existing literature by (1) reporting the number and percentages living in all four major settlement types rather than covering only one or two …
