The Complexities Of Irrigation Efficiency: Groundwater Data, Agro-Hydrology, And Water Decision-Making In Central Oregon, Rebecca Anderson, Alida Cantor
The Complexities Of Irrigation Efficiency: Groundwater Data, Agro-Hydrology, And Water Decision-Making In Central Oregon, Rebecca Anderson, Alida Cantor
Geography Faculty Publications and Presentations
Irrigation efficiency projects aim to conserve water for in-stream flow and agricultural use by reducing water losses throughout the system. Piping irrigation canals is a common irrigation efficiency method that results in trade-offs: while it increases efficiency of irrigation water conveyance, it reduces incidental groundwater recharge. This paper focuses on the data and decision-making of canal piping, focusing primarily on understanding the potential impacts of reduced canal leakage on shallow wells. By conducting a spatial analysis of shallow wells in the basin at risk of being impacted by canal piping, and combining this with interviews with water managers in central …
On Fire And Water: The Intersection Of Wetlands And Burning Strategies In Managing The Anthropogenic Plant Communities Of Yosemite National Park, Douglas Deur, Rochelle Bloom
On Fire And Water: The Intersection Of Wetlands And Burning Strategies In Managing The Anthropogenic Plant Communities Of Yosemite National Park, Douglas Deur, Rochelle Bloom
Anthropology Faculty Publications and Presentations
The existing literature confirms that Native American tribes historically enhanced culturally preferred plant communities through periodic burning in what is today Yosemite National Park; in turn, beginning with nineteenth-century park development, fire suppression contributed to conifer and shrub encroachment on anthropogenic meadows and other culturally significant habitats. However, we contend that traditional burning practices cannot be understood without considering the pronounced cultural role of wetland habitats and species, and the intersection between burning practices and wetland plant communities among tribes of the Sierra Nevada Range. Our ethnographic investigations revealed that a majority of culturally important plants identified by tribal members …

Changes in land-use practices have been a central element of human adaptation to Holocene climate change. Many practices that result in the short-term stabilization of socio-natural systems, however, have longer-term, unanticipated consequences that present cascading challenges for human subsistence strategies and opportunities for subsequent adaptations. Investigating complex sequences of interaction between climate change and human land-use in the past—rather than short-term causes and effects—is therefore essential for understanding processes of adaptation and change, but this approach has been stymied by a lack of suitably-scaled paleoecological data. Through a highresolution paleoecological analysis, we provide a 7000-year history of changing climate and …
Modeling Injury Severity Of Truck-Involved Crashes Under Covid-19 Regulatory Changes, William Mckenzie
Modeling Injury Severity Of Truck-Involved Crashes Under Covid-19 Regulatory Changes, William Mckenzie
Civil and Environmental Engineering Master's Project Reports
At the start of the pandemic the Federal Motor Carrier Safety Administration issued declaration No. 2020-002 which included a long list of goods given temporary emergency relief (deregulation) from national statutes 49 CFR Parts 390-399 of the Federal Motor Carrier Safety Regulations that oversee trucking. In particular, this granted emergency relief from Title 49 CFR § 395.3: maximum driving time for motor carriers or their drivers, regarded as hours-of-service (HOS), and subsequently further expanded to include short-haul trips, adverse driving conditions, break requirements, and sleeper berths. Regulations which play a crucial role in establishing the safe operation and management of …

Comparison Of Emissions Across Tobacco Products: A Slippery Slope In Tobacco Control, Ahmad El-Hellani, Ayomipo Adeniji, Hanno C. Erythropel, Thomas Lamb, Qixin Wang, Vladimir Mikheev, Robert Strongin, Multiple Additional Authors
Chemistry Faculty Publications and Presentations
In this narrative review, we highlight the challenges of comparing emissions from different tobacco products under controlled laboratory settings (using smoking/ vaping machines). We focus on tobacco products that generate inhalable smoke or aerosol, such as cigarettes, cigars, hookah, electronic cigarettes, and heated tobacco products. We discuss challenges associated with sample generation including variability of smoking/vaping machines, lack of standardized adaptors that connect smoking/vaping machines to different tobacco products, puffing protocols that are not representative of actual use, and sample generation session length (minutes or number of puffs) that depends on product characteristics. We also discuss the challenges of physically …

The objective of the current study is to examine monthly air passenger departures at the airport level considering spatial interactions between airports. In this study, we develop a novel spatial grouped generalized ordered probit (SGGOP) model system of monthly air passenger departures at the airport level. Specifically, we estimate two variants of spatial models including spatial lag model and spatial error model. In the presence of repeated demand measures for the airports, we also consider temporal variations of spatial correlation effects among proximally located airports by employing space and time-based weight matrix. The proposed model is estimated using monthly air …

Teaching excellence in higher education can be defined and studied in different ways, but research efforts to date have often focused on institutional or instructor perspectives. This article uses a data set of over 500 open-ended comments submitted by Political Science undergraduates as part of a teaching award process to identify themes that matter most to students. We find that being supportive, bringing humor, enthusiasm, and passion to the classroom, and engaging students with relevant, challenging, and exciting activities are what defines teaching excellence from a student’s perspective. Building on these themes and using quotes to illustrate key concepts, we …

Non-Native Rhizophora Mangle As Sinks For Coastal Contamination On Moloka’I, Hawai’I, Geoffrey Szafranski, Elise F. Granek, Michelle L. Hladik, Mia Hackett
Environmental Science and Management Faculty Publications and Presentations
Coastal mangrove forests provide a suite of environmental services, including sequestration of anthropogenic contamination. Yet, research lags on the environmental fate and potential human health risks of mangrove-sequestered contaminants in the context of mangrove removal for development and range shifts due to climate change. To address this, we conducted a study on Moloka'i, Hawai'i, comparing microplastic and pesticide contamination in coastal compartments both at areas modified by non-native red mangroves (Rhizophora mangle) and unmodified, open coastline. Sediment, porewater, and mangrove plant tissues were collected to quantify microplastic and pesticide concentrations across ecosystem type. Average microplastics were similar between …
A Memoir Of My Reading, Bennett B. Gilbert
A Memoir Of My Reading, Bennett B. Gilbert
History Faculty Publications and Presentations
Surveying nearly seven decades of habitual and obsessive reading, I consider how my character and psychology used reading to shape philosophical questions that move me into forms in which I could pursue them by reading. This became both the method and the substance of my philosophical work. It preserved some core emotional issues but also gave me the way to integrate them into scholarship and into my life.
Does El Niño Affect Mjo-Ar Connections Over The North Pacific And Associated North American Precipitation?, Laís G. Fernandes, Paul Loikith
Does El Niño Affect Mjo-Ar Connections Over The North Pacific And Associated North American Precipitation?, Laís G. Fernandes, Paul Loikith
Geography Faculty Publications and Presentations
This study investigates how the El Niño phase (EN) of the El Niño-Southern Oscillation (ENSO) influences the Madden-Julian Oscillation (MJO) modulation of cool-season North Pacific atmospheric rivers (ARs) and associated AR-landfall North American precipitation between 1980 and 2020. EN changes the key drivers of MJO-AR connections by shifting MJO-driven convection east of 180° in MJO phases 6–8 and extending the northern Pacific subtropical jet eastward. Under these conditions, the MJO tropical-extratropical teleconnection is triggered east of 180° in phases 7–8, and a persistent cyclonic flow anomaly develops along the United States west coast. Anomalous northeastward integrated water vapor transport (IVT) …
Is The Future Female? Lessons From A Conjoint Experiment On Voter Preferences In Six Arab Countries, Ellen Lust, Lindsay J. Benstead
Is The Future Female? Lessons From A Conjoint Experiment On Voter Preferences In Six Arab Countries, Ellen Lust, Lindsay J. Benstead
Political Science Faculty Publications and Presentations
Despite growing evidence of pro-female bias in the electorate elsewhere, conventional wisdom holds that voters in the Middle East and North Africa (MENA) prefer male candidates, presumably due to sexism. We test this conventional wisdom using a conjoint experiment administered to over 30,000 respondents in six MENA countries. We find both male and female respondents are more likely to express support for female candidates and see them as more capable than their male counterparts, even in stereotypically male domains. We argue the increasing demand for political outsiders explains these results. In highlighting the importance of such changes, our study expands …

Beavers, Hydrology, And Wapato: A Baseline For Monitoring Franz Lake National Wildlife Refuge, Justine Casebolt
Beavers, Hydrology, And Wapato: A Baseline For Monitoring Franz Lake National Wildlife Refuge, Justine Casebolt
Environmental Science and Management Professional Master's Project Reports
Located in the lower Columbia River floodplain, Franz Lake National Wildlife Refuge is a unique landscape with a complex land use history. For thousands of years, Indigenous tribes lived on this land. In the early 1990s, U.S. Fish and Wildlife Service acquired the land, after it was identified as a mitigation site following the construction of the Bonneville Lock and Dam. Franz Lake Refuge was once known for its prevalent Wapato (Sagittaria latifolia) population, an emergent plant with edible tubers and an important food source for Indigenous people. With specific growth requirements and hydrologic conditions for germination and …

Prose By Any Other Name: Analyzing Changes To Translated Book Titles In Japanese And English, Angela Griffin
Book Publishing Final Research Papers
This research analyzed the ways in which book titles are changed in translation from English to Japanese and Japanese to English. The titles of one hundred books, fifty in Japanese and fifty in English, were sorted into three main categories of translation based on Tsukawaki’s research on translated sci-fi movie titles (2009): those using the Japanese katakana script, literal, and semantic. For Japanese to English titles, literal translations accounted for 68% of the data and semantic translations for 20%, while Japanese to English titles were literally translated only 48% of the time but semantically 34%. The changes made to translated …

Digital Comics Subscription Service Usage And Its Impact On Printed Comic Buying Habits: The Digital Comics Subscription Loop, Isaac Swindle
Book Publishing Final Research Papers
This study developed a digital comics subscription loop that borrows from consumer loyalty research done in publishing and marketing studies. The proposed loop uses comic publisher’s proprietary subscription platforms as a “book showroom” to allow consumers to sample titles, driving physical sales. Original survey data was then gathered about comic book consumers’ usage of digital subscription platforms and what drives them to make physical purchases. The data was then compared to the proposed model, finding significant cross-medium consumption, as well as many reported completions of the Digital Comics Subscription Loop. The survey data found that over 80 percent of respondents …

Exploring Consent: An Analysis Of Consent In Dark Romance And Contemporary Romance Books, Janeth Hernandez
Exploring Consent: An Analysis Of Consent In Dark Romance And Contemporary Romance Books, Janeth Hernandez
Book Publishing Final Research Papers
This research paper analyzes whether consent is found more frequently in dark romance or contemporary romance books by examining the language used, who speaks the phrases, and the contexts in which they are spoken. This paper explores the dominant sexual script in contemporary romance books and its influence on representations of consent, contrasting this with the absence of such a script in dark romance, which permits more varied incorporations of consent. This analysis was done through content analysis-- word frequency, consent analysis, and thematic coding. Word frequency provided evidence of consent use in the books, while consent analysis and thematic …

Mathematics and Statistics Faculty Publications and Presentations
Learning nonparametric systems of Ordinary Differential Equations (ODEs) from noisy data is an emerging machine learning topic. We use the well-developed theory of Reproducing Kernel Hilbert Spaces (RKHS) to define candidates for for which the solution of the ODE exists and is unique. Learning consists of solving a constrained optimization problem in an RKHS. We propose a penalty method that iteratively uses the Representer theorem and Euler approximations to provide a numerical solution. We prove a generalization bound for the distance between and its estimator. Experiments are provided for the FitzHugh-Nagumo oscillator, the Lorenz system, and for predicting the Amyloid …
Dynamic Fibrillar Assembly Of Αb-Crystallin Induced By Perturbation Of The Conserved Nt-Ixi Motif Resolved By Cryo-Em, Russell Mcfarland, Steve Reichow
Dynamic Fibrillar Assembly Of Αb-Crystallin Induced By Perturbation Of The Conserved Nt-Ixi Motif Resolved By Cryo-Em, Russell Mcfarland, Steve Reichow
Chemistry Faculty Publications and Presentations
αB-crystallin is an archetypical member of the small heat-shock proteins (sHSPs) vital for cellular proteostasis and mitigating protein misfolding diseases. Gaining insights into the principles defining their molecular organization and chaperone function have been hindered by intrinsic dynamic properties and limited high-resolution structural analysis. To disentangle the mechanistic underpinnings of these dynamical properties, we mutated a conserved IXI-motif located within the N-terminal (NT) domain of human αB-crystallin. This resulted in a profound structural transformation, from highly polydispersed caged-like native assemblies into a comparatively well-ordered helical fibril state amenable to high-resolution cryo-EM analysis. The reversible nature of the induced fibrils facilitated …
Birkhoff Summation Of Irrational Rotations: A Surprising Result For The Golden Mean, Heather Moore
Birkhoff Summation Of Irrational Rotations: A Surprising Result For The Golden Mean, Heather Moore
University Honors Theses
This thesis presents a surprising result that the difference in certain sums of constant rotations by the golden mean approaches exactly 1/5. Specifically, we focus on the Birkhoff sums of these rotations, with the number of terms equal to squared Fibonacci numbers. The proof relies on the properties of continued fraction approximants, Vajda's identity and the explicit formula for the Fibonacci numbers.
Intersectionalities Of Systematic Barriers Set Upon Underrepresented Students In Stem: Capturing The Potential Benefits Of Online Modality, Raiyasha Aiyanna Paris
Intersectionalities Of Systematic Barriers Set Upon Underrepresented Students In Stem: Capturing The Potential Benefits Of Online Modality, Raiyasha Aiyanna Paris
University Honors Theses
The prevalence of racism and microaggressions in STEM disciplines within colleges presents significant hurdles to the academic success and well-being of underrepresented students. Microaggressions, encompassing subtle biases and stereotyping, have a cumulative impact, inducing heightened stress, diminished motivation, and reduced self-efficacy among minority students, thereby impeding cognitive functioning and hindering academic progress (Ogunyemi et al., 2020). The existence of these negative emotional responses creates a less conducive learning environment for academic achievement. Additionally, structural inequalities within STEM institutions contribute to disparities in resource access, limited mentorship opportunities, and support networks crucial for success in STEM fields (Atkins et al., 2020). …
The Wage Of Wellness: The Relationship Between Socioeconomic Status, Race, And Work Recovery, Emily Julia Ready
The Wage Of Wellness: The Relationship Between Socioeconomic Status, Race, And Work Recovery, Emily Julia Ready
Dissertations and Theses
A substantial share of the workforce is made up of low-income workers. Many of these workers fall below the federal poverty line and are considered low socioeconomic status (SES) and are disproportionately more likely to be racial minorities. However, this population is often neglected in the industrial-organizational psychological literature. Specifically, work recovery research has not considered the unique life circumstances of this particular group in the development of the research questions, theoretical framework, or practical implications in relation to this phenomenon. The purpose of the current study is to understand the relationship between socioeconomic status, race, and work recovery experiences …
Gut Feelings: A Literature Review On The Gut-Brain Axis And Its Potential Influence On Mood, Grace Johnson
Gut Feelings: A Literature Review On The Gut-Brain Axis And Its Potential Influence On Mood, Grace Johnson
University Honors Theses
In recent decades, research on the gut-brain axis has evolved due to an increasing interest in the connection between gut health and mental health. The gut-brain axis presents a new frontier of health for both medical professionals and psychologists as there is expanding evidence illustrating the comorbidity of gut disorders and mood disorders. Due to the complex nature of studying the gut-brain axis and the myriad of influences on mood disorders such as depression, research has yet to find significant results definitively tying the two together. Nonetheless, the current body of literature on the topic provides a promising outlook on …

BACKGROUND. Vaccination is typically administered without regard to site of prior vaccination, but this factor may substantially affect downstream immune responses. METHODS. We assessed serological responses to initial COVID-19 vaccination in baseline seronegative adults who received second-dose boosters in the ipsilateral or contralateral arm relative to initial vaccination. We measured serum SARSCoV-2 spike–specific Ig, receptor-binding domain–specific (RBD-specific) IgG, SARS-CoV-2 nucleocapsid–specific IgG, and neutralizing antibody titers against SARS-CoV-2.D614G (early strain) and SARS-CoV-2.B.1.1.529 (Omicron) at approximately 0.6, 8, and 14 months after boosting. RESULTS. In 947 individuals, contralateral boosting was associated with higher spike-specific serum Ig, and this effect increased over time, …

Corporatizing Violence: Targeted Repression Of Indigenous Dissent In Democratic States, Laikaika Layne Rivera
Corporatizing Violence: Targeted Repression Of Indigenous Dissent In Democratic States, Laikaika Layne Rivera
Dissertations and Theses
This thesis explores state repression of disruptive protests against private development projects in democracies. Using a mixed methods approach, including logistic regression and case studies, the research identifies key factors influencing repression. Indigenous leadership, fragmented public opposition, and private elite influence increase the likelihood of violent repression. The findings suggest that when public resistance is insufficient against powerful private interests, coercive institutions resort to violent strategies to quell disruptions and signal increased costs for future dissent. State repression is more likely when the protest movement is comprised of Indigenous groups than compared to those of the general public. The study …
Comparison Of Conventional And Adaptive Acoustic Beamforming Algorithms Using A Tetrahedral Microphone Array In Noisy Environments, Megan Brittany Ewers
Comparison Of Conventional And Adaptive Acoustic Beamforming Algorithms Using A Tetrahedral Microphone Array In Noisy Environments, Megan Brittany Ewers
Dissertations and Theses
In situ acoustic measurements are often plagued by interfering sound sources that occur within the measurement environment. Both adaptive and conventional beamforming algorithms, when applied to the outputs of a microphone array arranged in a tetrahedral geometry, are able to capture sound sources in desired directions and reject sound from unwanted directions. Adaptive algorithms may be able to measure a desired sound source with greater spatial precision, but require more calculations and, therefore, computational power. A conventional frequency-domain phase-shift algorithm and a modified adaptive frequency-domain Minimum Variance Distortionless Response (MVDR) algorithm were applied to simulated and recorded signals from a …
