Autofluorescence Microscopy: Identifying Bacterial Signals On Rock Samples, Noel Case

University Honors Theses

One common method for identifying microbes present in fluid and non-fluid samples is fluorescent dye staining, in which samples are stained with a fluorophore - a molecule excited by an external light source that re-emits energy as higher-wavelength light. The excitation wavelength used greatly impacts the observability of microbes in the resulting fluorescence images, and deep ultraviolet excitation (200-280 nm) seems to provide the highest signal-to-noise ratio of any excitation range. By inoculating rock samples (gypsum and marble) with B. subtilis, staining with SYTO 9, Acridine Orange and FM 1-43 dyes, and imaging with deep UV (275 nm), near …

Sleeping To Support: An Examination Of The Relationship Between Leader Sleep And Positive Support Behaviors, Jordyn Jan Leslie

Dissertations and Theses

Although research has documented the relationship between sleep and workplace outcomes among general employees, less research has focused on the role of sleep among workplace leaders. Drawing from the work, nonwork, and sleep theoretical model (Crain et al., 2018), the current study investigates emotional exhaustion the link between leader sleep quantity on a constellation of positive leader support behaviors (i.e., general supervisor support, family supportive supervisor behaviors (FSSB), and sleep leadership) rated by both the leader and their direct employee. To gain a deeper understanding of the role of sleep in these relationships, this study examines the interaction between sleep …

Climate And Intraspecific Geographic Variation Of Nests And Eggs In The Eastern Kingbird Tyrannus Tyrannus, Samantha Marie Gillette

Dissertations and Theses

The reproductive success of birds is ultimately driven by the traits of nests, eggs, and incubation behavior and the interactions among them. Avian reproduction varies on large geographic scales, most prominently between tropic- vs. temperate-breeding species, but also on finer scales, such as along latitudinal and elevational geographic gradients. However, despite the importance of eggs and nests, how their traits vary geographically in response to differences in regional climate remains understudied.

We studied Eastern Kingbirds (Tyrannus tyrannus), which have been previously demonstrated to alter incubation length in response to local climate conditions. Our study sites, Kansas (KS), New …

The Daughters Of The Fronde: French Aristocratic Women And The Subversion Of Bourbon Absolutist Culture, 1661-1727, Jordan David Hallmark

Dissertations and Theses

The turbulent events of the Fronde des Princes (Fronde of the Princes), which saw the French nobility stage a failed rebellion against the monarchical administration of France's chief minister, Cardinal Mazarin, between 1650 and 1652, have been portrayed in the existing historiography as the swan song of a pre-absolutist nobility seeking to preserve its feudal identity as the king's partner in governance and military affairs. Indeed, as many historians of early modern France have observed, the policies pursued by Cardinal Mazarin following the monarchy's victory over the rebel princes of the Fronde, and subsequently expanded upon by Louis XIV after …

Implicit Learning In Preschool Children With And Without Developmental Language Disorder, Abigail E. Tolomei

University Honors Theses

The study below was designed to compare implicit learning in fifty-two preschool-aged children with and without developmental language disorder (DLD) to test the Procedural Deficit Hypothesis (PDH). The PDH claims that procedural memory, the basis of implicit learning, is the main impairment in DLD. Using a computer-based program to conduct sound-meaning-mapping tasks, we asked children to select one of two images according to the corresponding sound they heard. After all the participants were tested, an additional cue was found in the experiment that impacted the data. Instead of the children attuning to the sounds to depict the correct answer, the …

Making A Monster: Queerness And Disability In Gothic Literature, Julien Draven

University Honors Theses

Scholars within the gothic genre have long been exploring the concept of the "other" within literature. Looking at the topics of queerness and disability through the lens of Bram Stoker's Dracula and Mary Shelley's Frankenstein it's clear that much of the rhetoric surrounding these identities in the 19th century is still very much present in modern society--even if it's worded a bit differently. This literature review covers how queerness and disability are related, disability, eugenics, sexuality, gender, and monstrosity all within the gothic genre of literature.

Lgbtq+ Congregants Navigating Identity In The Context Of "Welcoming But Not Affirming" Evangelical, Pentecostal, And Non-Denominational Religious Institutions: A Queer Narrative Analysis, Sarah E. Rasmussen

University Honors Theses

Welcoming but not affirming Evangelical, Pentecostal, and non-denominational churches invite LGBTQ+ people to attend their church, but do not affirm their identity as a gender and/or sexual minority. Because of this, they restrict LGBTQ+ attendees from participating in leadership, paid staff positions, and ministry work. LGBTQ+ attendees are often not aware of these restrictive policies initially. The current study aims to examine how LGBTQ+ people navigate their faith and identity within welcoming but not affirming church spaces through narrative analysis. Fifteen participants engaged in an interview, where they were asked about their experience within welcoming but not affirming church spaces. …

"There Is Great And Awful Immorality In This Place": Environment, Character, And Reform In South Wales, 1847-1919, Allison Kirkpatrick

University Honors Theses

In the second half of the nineteenth century and beginning of the twentieth, sanitarians and reformers in Britain undertook a wide range of public health campaigns aimed at improving the conditions of the industrialized urban environment. Some turned their attention to south Wales, where the coal industry had spurred rapid urban growth and transformed the region into one of Britain's industrial centers. The negative effects of this transition were most acutely felt in working-class communities in the south Wales coalfield, where a near-complete lack of urban planning had left a legacy of overcrowding, nonexistent or inadequate drainage and sewage systems, …

Gender Inequality And The Division Of Labor In The Home During Covid-19: A Literature Review, Ella F. Jackson

University Honors Theses

The current Covid-19 pandemic has dramatically impacted families in the United States as working parents face increased demand for domestic labor at home while losing community and institutional support through pandemic closures. By integrating emerging research on gender norms and expectations regarding the division of household labor for working parents, the impact of Covid-19 on working mothers, and the gendered impact of infrastructure and the pandemic response in the United States, I aim to provide a holistic conceptualization and analysis of gender inequality and the division of labor in the home during the Covid-19 pandemic. Through summarizing and analyzing current …

Detection And Quantification Of Arsenic Pollution With A Moss Bio-Indicator And Icp-Ms, Erin R. Bowey

University Honors Theses

Heavy metal pollution is a recognized concern with an established source of anthropogenic activity, which is ever-increasing. While work has been done to make the monitoring of some metals more accessible, resourceful, and efficient with the use of epiphytic moss as a bio-indicator, this method has not been optimized for the detection of arsenic. Previously used analytical instrumentation has not proven sensitive enough to reliably detect arsenic, creating a gap in the monitoring process. However, inductively coupled plasma mass spectrometry (ICP-MS) is proposed as the solution to fill this gap. Its potential for low limits of detection and quantification express …

In Sickness And In Health: Parasites Of Stranded Pacific Harbor Seals (Phoca Vitulina Richardii) In Northern Oregon And Southern Washington, Cecily Douglas Bronson

Dissertations and Theses

Parasites have the capability to infect virtually every living organism on the planet and have adapted to infiltrate every trophic level. Many species have complex indirect life cycles and rely upon hosts at different levels of the food web for growth and reproduction. In the marine environment, having a high level of parasite diversity is thought to indicate a more stable ecosystem than an environment with low parasite diversity. As one of the top predators in their environment and because of their amphibious behaviors, pinnipeds (seals and sea lions) are exposed to a wide variety of parasites, making them ideal …

Artemisia Gentileschi: A Deeper Look Into Burghley House Susanna, Emma M. Rochlin

The purpose of this study is to understand the efficacy of telehealth as a pediatric occupational therapy modality and expose variables effecting treatment quality.

I created a survey in Qualtrics, a web-based software. The target population was pediatric occupational therapists (OTs) licensed in Oregon. Qualitative and quantitative questions addressed respondent qualifications, telehealth and pediatric occupational therapy …

Finding The Balance: Music Performance Anxiety, Flow, And The Undergraduate Recital, Ash Phillips

University Honors Theses

In a combination of research-oriented and creative endeavors, I analyzed and reflected on my own struggles with music performance anxiety (MPA) in hopes to manage my levels of MPA for my undergraduate recital. Through this deep dive, I discovered numerous strategies for minimizing MPA, including (but not limited to): physical activity, meditation, and the concept of flow. Of all the techniques I implemented into my practice, the concept of flow proved to be the most beneficial by far. Flow experiences occur when an individual is so enveloped in their craft (music, art, athletics, etc) that they lose touch with their …

Electron Backscatter Diffraction Analysis Of Olivine In Ureilite Meteorites: Evaluation Of The Partially Magmatic Catastrophic Disruption Model Of The Ureilite Parent Body (Upb), James Karl Frye

Dissertations and Theses

Past studies of olivine have yielded insights into crystallographic slip systems and how they are activated thermally. Using this information in conjunction with Electron Backscatter Diffraction (EBSD) analysis and metrics developed for chondrites, I constrained the thermal environment and the cooling rate for four ureilite meteorites in an attempt to test the model of catastrophic disruption of the ureilite parent body while it was partly molten. Present evidence for deformation, along with thermal metrics, were examined in order to conclude the following: Deformation of the meteorites took place at high temperatures followed by swift cooling, leaving little time for annealing. …

Do Motives Matter? The Role Of Motivation In Shaping The Impact Of Mindfulness Training On Teachers' Psychological Distress And Wellbeing, Cristi N. Pinela

Dissertations and Theses

Research on the impacts of mindfulness trainings (MTs) on teachers' psychological health and wellbeing suggests that MTs may be especially well-suited to preparing teachers for the unique demands of the profession. However, few studies have investigated whether different teachers benefit in different ways from mindfulness training, although there is some evidence that mindfulness training may yield dissociable benefits and preliminary evidence of differential effects of MTs on subgroup of teachers. The paucity of empirical evidence may be partly attributed to the paucity of theoretical frameworks that identify possible mechanisms for differential effects. The present study stepped into this gap by …

Examining Probation Lengths In Philadelphia, Pa, Madeline Grace Davis

Dissertations and Theses

One out of every 22 adults in Philadelphia, PA is under community supervision which is more than double the national average (Schiraldi, 2018). Even though probation has been seen as a more lenient alternative to prison it actually serves as a net-widener (Phelps, 2020). Probation can result in increased punishments for low-level offenses when failure to meet probation conditions results in jail or prison time when there was never a possibility of long-term incarceration at the time of sentencing (Phelps, 2020). This study uses public court information data from Philadelphia to analyze the effects different dosages of probation have on …

What Happened To The “New Middle Class”? The 2016 Borp (Brazil’S Once-Rising Poor) Survey, Benjamin Junge, Sean T. Mitchell, Charles H. Klein, David De Micheli

Anthropology Faculty Publications and Presentations

This research note provides a detailed account of the development and implementation of a household survey conducted in 2016 as part of a larger investigation into the lifeways and political subjectivities of Brazil’s “once-rising poor,” the demographic sector comprising poor and working-class people who experienced various forms of socioeconomic mobility in the early twenty-first century. After reflecting on the challenges of maintaining a critical perspective on class labels and relations that were intensely contested at the time, the article introduces the survey sample (n = 1,204), highlighting variables captured. It then establishes the demographic profile, mobility experiences, political values, attitudes, …

The study will seek to determine the importance of doux commerce to the evolutionary progression of societies and their economies during the eighteenth century, its role in the dissolution of mercantilism, and its position in the rise of free trade and industrial capitalism during the nineteenth century. The concept has only recently been …

In Their Own Words: Examining The Educational Experiences, Expectations, And Values Of Oregon Low-Income, Single Black Mothers, Reiko Mia Williams

Dissertations and Theses

The long-standing achievement gap between African-American students in grades k-12 and their White counterparts has inspired many educational leaders and policy makers to seek a deeper, more comprehensive understanding of the various factors affecting the well-being of Black students. The conversation has historically focused on deficits and dysfunction while ignoring strengths and resiliencies. The research in this study investigates inaccuracies regarding Black families in order to change the conversation from one of deficits to a strength-based lens. In spite of the inequities that exist for Black families with regards to housing, employment, and health, Black parents remain committed to ensuring …

The Mechanisms Connecting State Marijuana Policies To Parent, Peer, And Youth Drug Perception Leading To Youth Marijuana Use, Eunbyeor Sophie Yang

Dissertations and Theses

Youth marijuana use, which can lead to numerous health problems, is significantly associated with youth drug perception, which is greatly influenced by state marijuana laws such as medical marijuana legalization and penalty severity. The mediating impact of social drug perceptions on the association between state marijuana laws and youth drug disapproval is not well known. Based on theory of change and primary socialization theory, this study examined the impact of state marijuana laws on youth drug disapproval, the mediating factors of parent and peer drug disapproval, the direct effect of youth drug disapproval on youth marijuana use, and the moderating …

"I'M Very Enlightened:" Assisting Black Males Involved In The Criminal Justice System To Deal With And Heal From Racism, Darnell Jackie Strong

Dissertations and Theses

Black Males who have offended face major challenges stemming from their involvement in the Criminal Justice System. Once involved it is hard to get out, as exhibited by high recidivism rates and mass incarceration, issues that have plagued Black Males since slavery. There is little research on interventions to ameliorate the effects of racism on this population.

The aim of this research was to: a) create a training to help Black Males who have been involved in the Criminal Justice System deal with racism and b) evaluate the intervention. This mixed methods research utilized Constructivist Grounded Theory and Afrocentric theory …

Transforming Learning Communities, Transforming Ourselves: A Qualitative Investigation Of Identity Processes In A Participatory Action Research-Themed Undergraduate Course, Julia Sara Dancis

Dissertations and Theses

In contrast to the dominant, post-positivist approaches to research in psychology, participatory action research (PAR) programs aim to democratize knowledge production and participate in social action through explicitly value-based and politicized agendas. Despite the inclusive nature of this work, college students are often left out of PAR collaborations and rarely even exposed to this frame of research. The handful of researcher-educators who have conducted participatory and action-oriented research with undergraduate students report a range of benefits for students, their universities, and the surrounding communities, confirming its importance. Left unaddressed are the key identity processes that unfold during knowledge production and …

Transportation Mode Choice Behavior In The Era Of Autonomous Vehicles: The Application Of Discrete Choice Modeling And Machine Learning, Sangwan Lee

Dissertations and Theses

New mobility technologies, such as shared mobility services (e.g., car-sharing) and, more importantly, autonomous vehicles (AVs), continue to evolve. The supply-side advancement will likely disrupt and transform transportation mode choice behaviors, and create a new paradigm since they are emerging and becoming increasingly feasible alternatives to the existing modes of transportation. Accordingly, this dissertation employs discrete choice modeling (DCM) and machine learning (ML) using a U.S. nationwide stated choice experiment to understand how travelers adopt new transportation modes or continue to use conventional modes of transportation.

This dissertation consists of three papers. The first examines future market shares of each …

Masculinity Instability And Ideologies As Predictors Of Ipv Perpetration: The Mediating Role Of Relationship Power, Emma Christine Marioles O'Connor

Dissertations and Theses

Intimate partner violence (IPV) is considered to be a pervasive and devastating social issue and is disproportionately perpetrated by men (CDC). Masculinity ideologies, which are comprised of male role norm expectations, inform boys and men about what it means to be and to not be "a man" and have been established as a predictive factor of men's IPV perpetration. These ideologies serve to maintain existing social hierarchies that entitle men to seek socially dominant and powerful positions in society, as well as within their intimate relationships. Further, masculinity is considered to be unstable, subject to threat, and in need of …

Mapping Ecosystem Service Flows Of Estuary Restoration Projects On The Oregon Coast To Identify Impacted Stakeholders, Shersten King Finley

Dissertations and Theses

The recent impetus for estuarine restoration has largely focused on resolving key ecological problems; however, less is known about how people might benefit or be impacted by restoration. By mapping benefits that flow from functional salt marshes and estuarine systems I examined how different social groups might be impacted by restoration based on race and class. In this study, I considered three ecosystem services (recreation, aesthetics, cultural/historical/spiritual) and where they might impact surrounding communities. In this paper I argue that stakeholder groups can be identified by mapping ecosystem service flow areas. I hypothesized that these three ecosystem services would have …

"We've Created Cheap Energy Off The Backs Of Salmon": Dam Removal Politics And Alliances In The Lower Snake River Basin, Krista Harrington

Dissertations and Theses

Dams, once considered by many to be good for water development in the Western U.S., might not be a part of a climate resilient future. Dams have come under increasing scrutiny due to undesirable ecological implications. Although dam removal proposals are growingly popular in recent decades, they are controversial since they impact different stakeholders in different ways. In the Pacific Northwest, the Lower four Snake River dams have long been criticized for their negative impacts on salmon. In February 2021, US Congressman Mike Simpson (R-Idaho) proposed a comprehensive framework to deconstruct the Lower four Snake River dams as an attempt …
