University Honors Theses

Children are brought into this world under many different circumstances and to many different families. Some are planned, some are not; all come from families with a range of income, relationship status, and experiences. Throughout a child's life, there can be many changes in the family unit that impact the ways parents are available to care for their children. This includes divorce/separation, incarceration, co-parenting, married life, etc., relationship statuses may change over time. Different life stressors impact the financial wellbeing of a family and parents’ ability to spend time with their children. This study used secondary data analysis of the …

Perversion: A Genealogy Of Deviance And Creation Of The "Other", J D. Lyell

University Honors Theses

Drawing from Thomas Aquinas' Theory of Natural Law, I investigate Euro-Christian conceptions of naturalness and unnaturalness and how they were weaponized to cast racialized groups as perverse in the construction of the United States. I focus on the enforcement of Euro-heteropatriarchy to demonize Indigenous family and gender structures, as well as the characterization of Black bodies as abnormal by white academia to demonstrate some of the ways gender and sexuality have been colonized in the U.S. My research provides a general outline tracing a genealogy of deviance as established by Euro-Christian norms of sexuality and gender, which emerges from a …

Minimality Of Integer Bar Visibility Graphs, Emily Dehoff

University Honors Theses

A visibility representation is an association between the set of vertices in a graph and a set of objects in the plane such that two objects have an unobstructed, positive-width line of sight between them if and only if their two associated vertices are adjacent. In this paper, we focus on integer bar visibility graphs (IBVGs), which use horizontal line segments with integer endpoints to represent the vertices of a given graph. We present results on the exact widths of IBVGs of paths, cycles, and stars, and lower bounds on trees and general graphs. In our main results, we find …

This thesis will analyze the social media marketing (SMM) practices of Fast Fashion industry trends that have surfaced due to recent events. Specifically, this work will compare customer-facing SMM efforts related to diversity, equity, and inclusion (DEI) initiatives against the internal values and practices a company expends towards these efforts. This thesis will use H&M as an illustrative example in representing a company within the Fast Fashion industry. The motivation of this thesis or[i]ginates from the ongoing shifts in corporate SMM practices after the murder of George Floyd in May of 2020 and the corresponding increase in social justice activism …

Immigration Federalism In The United States: Constructing A Contemporary Institutional Framework Centered On Local Communities Through A Case Study Approach, Sara Kuehlhorn Friedman

Dissertations and Theses

This research study presents a new model of immigration federalism which integrates existing theories into a framework that emphasizes agency at the local level. Unlike dominant models of federalism that observe the cascading effect of higher-level policy on lower levels of government, this research focuses on empirical evidence at the local level to understand its relation to policy at higher levels. Immigration federalism is receiving substantial interest in scholarly work and in practice, but it lacks a cohesive and comprehensive theory explaining variation at the community level. There is little reason to expect sweeping changes in immigration policy at the …

Efficient Capture Of Co2 And Its Selective Reduction To Formic Acid Using Tin-Based Nanomaterials, Emmanuel Oluwaseun Abdul

Dissertations and Theses

CO₂ emissions from the combustion of fossil fuels and other anthropogenic sources have become the main contributing factors to global warming. Chemical methods of absorbing/capturing CO₂ from combustion flue gases have made it a sought-after approach in engineering emission solutions because of its simplistic and convenient operation and high absorption efficiency. The conversion of CO₂ into renewable fuels and high energy density chemicals by clean and economic processes has drawn scientists' attention over the decades. The electrocatalytic conversion of CO₂ using Sn-based materials has been demonstrated to be a promising method for producing formate, an important …

A Tale Of Two-Hybrids: Investigating The Interactomes Of Cullin-Associated Proteins, Elyse Reitter

Dissertations and Theses

Cul3 is the major component of an E3 ligase in human cells. Cul3 was initially identified in the Singer lab as a protein that binds and degrades cyclin E, and subsequent studies have shown it to be part of a complex that is involved in a multitude of biological functions. The nature of this complex, its constituents, its regulation, and its dynamics is just beginning to be understood. The research presented here utilizes a series of two hybrid screens to identify families of interactomes with Cul3 at the center. This information will complement other work in the lab in which …

Measurement Of Fruit And Vegetable Intake Incorporating A Diversity, Equity, And Inclusion Lens. Comment On Di Noia, J.; Gellermann, W. Use Of The Spectroscopy-Based Veggie Meter® To Objectively Assess Fruit And Vegetable Intake In Low-Income Adults, Carmen Byker Shanks, Betty Izumi, Courtney A. Parks, Amy L. Yaroch

OHSU-PSU School of Public Health Faculty Publications and Presentations

Disparities in fruit and vegetable intake (FVI) and diet-related diseases exist among low-income and racial/ethnic minority populations [1,2,3,4]. Intervention approaches to eliminate FVI disparities frequently utilize dietary assessment to measure impact. Studies measure FVI in varying ways, but do not fully account for diversity, equity, and inclusion (DEI).

Speciation Of Diaryliodonium Salts In Solution And Their Reactivity Towards N-Nucleophiles (Phthalimide And Amines) And O-Nucleophiles (Phenols And Phenoxide), Souradeep Basu

Dissertations and Theses

Benzenoid rings are prevalent in pharmaceutical drug molecules, agrochemical molecules and even in some polymers used in electronic device. Aryl rings are often installed using metal catalysis, however, metal free arylations are known but limited. Diaryliodonium salts are novel electrophilic arylating agents. Herein, metal free N-arylation of phthalimide and diarylether formation using aryl(TMP)iodonium salts is described.

The structure of diaryliodonium salts has been primarily studied in either the solid state or in-silico. The structure and speciation of diaryliodonium salts in solution is not well explored. In this work evidence of dimer formation of aryl(Mes)iodonium salts in chloroform using …

Bwana, David Bangsberg, Multiple Additional Authors

OHSU-PSU School of Public Health Faculty Publications and Presentations

Introduction: Antiretroviral pre-exposure prophylaxis (PrEP) may reduce periconception and pregnancy HIV incidence among women in settings, where gender power imbalances limit HIV testing, engagement in care and HIV viral suppression. We conducted qualitative interviews to understand factors influencing periconception and pregnancy PrEP uptake and use in a cohort of women (Trial registration: NCT03832530) offered safer conception counselling in rural Southwestern Uganda, where PrEP uptake was high. Methods: Between March 2018 and January 2019, in-depth interviews informed by conceptual frameworks for periconception risk reduction and PrEP adherence were conducted with 37 women including those with ≥80% and

Helminths Of Thomomys Species (Rodentia: Geomyidae) Of Oregon, Malorri Rene Hughes

Dissertations and Theses

Although often viewed as inconsequential, parasites have significant ecological and evolutionary importance, and studying them can generate knowledge regarding their environments and their hosts. Helminths (intestinal parasites) infecting Western pocket gophers (Thomomys species) in Oregon had been documented based only on morphology prior to this study. Basing parasite identification solely on morphology is problematic because the characteristics used to identify species can be vague or similar, leading to misidentification or obscuring the true biodiversity present. Using molecular markers to verify species present not only is more reliable but also can be informative in terms of the host-parasite association. To …

Can We Do Better Next Time? Italians’ Response To The Covid-19 Emergency Through A Heuristics And Biases Lens, Raffaella Misuraca, Ursina Teuscher, Costanza Scaffidi Abbate, Francesco Ceresia, Michelle Roccella, Lucia Parisi, Luigi Vetri, Silvana Miceli

Psychology Faculty Publications and Presentations

During the outbreak of COVID-19 in Italy, people often failed to adopt behaviors that could have stopped, or at least slowed down, the spread of this deadly disease. We offer cognitive explanations for these decisions, based on some of the most common heuristics and biases that are known to influence human judgment and decision-making, especially under conditions of high uncertainty. Our analysis concludes with the following recommendations: policymakers can and should take advantage of this established science, in order to communicate more effectively and increase the likelihood that people choose responsible actions in a public health crisis.

An Automated Zoom Class Session Analysis Tool To Improve Education, Jack Arlo Cannon Ii

Dissertations and Theses

The recent shift towards remote education has presented new challenges for instructors with respect to teaching evaluation. Students in traditional classrooms send signals to instructors which provide feedback for the effectiveness of a given lecture. Virtual learning environments lack some of these communication channels and require new ways of collecting feedback. This work presents a suite of analysis tools for the virtual instructor. Given the transcript and video files for a Zoom meeting, this tool summarizes student sentiment and speaking characteristics. Sentiment scores are derived using state of the art Natural Language Processing (NLP) models. The video file is used …

Linear Nearest Neighbor Flocks With All Distinct Agents, Robert G. Lyons

Dissertations and Theses

This dissertation analyzes the global dynamics of 1-dimensional agent arrays with nearest neighbor linear couplings. The equations of motion are second order linear ODE's with constant coefficients. The novel part of this research is that the couplings are different for each agent. We allow the forces to depend on the relative position and relative velocity (damping terms) of the agents, and the coupling magnitudes differ for each agent. Further, we do not assume that the forces are "Newtonian'" (i.e., the force due to A on B equals minus the force of B on A) as this assumption does not apply …

Intersections Of Masculinity, Culturally Relevant Factors, And Intimate Partner Violence Perpetration Among Asian American Men, Jason Z. Kyler-Yano

Dissertations and Theses

Intimate partner violence (IPV) by men against women is a devastating social problem that is experienced by over a quarter of women in their lifetimes (Tjaden & Thoennes, 2000). IPV in Asian American communities is a prevalent problem that is likely influenced by both patriarchal gender role norms as well as culturally salience factors that are distinct to Asian Americans. Given the influence of norms and values on gendered power dynamics and racial power dynamics in the U.S., it is important to understand the intersections of gender and culture in Asian American men's masculine role norms and IPV perpetration. This …

Space And Identity In J.M. Coetzee's Life & Times Of Michael K, Joshua Baker

University Honors Theses

Occupying colonial governments establish and maintain power through the demarcation and control of space, a process Sara Upstone terms "overwriting". In Life & Times of Michael K, Coetzee imagines the complication of establishing and maintaining a self-identity amid the strict control of space in post-apartheid, wartime South Africa, and it is this conflict of identity which comprises the novel’s subplot. The reader follows Michael K's odyssey over hundreds of miles in his quest to find the farm on which his mother was born and raised. His journey is repeatedly thwarted by state actors who enforce a strict control of movement …

A Biomimetic Model For Oxidative Metabolism Of Thiopurine Drugs, Oluyemi Oludare Alo

Dissertations and Theses

Type B hepatotoxicity has been reported for thiopurines, and this has limited their clinical uses. Although a lot of research has been done on thiopurines, the precise mechanism of their hepatotoxicity is still unclear. The results of the in vitro and in vivo experiments aimed at assessing the products of their CYP450-mediated bioactivation have been contradictory. Although it has been theorized that the hepatic toxicity of this class of drug is caused by their bioactivation to electrophilic reactive metabolite (RM) and concomitant protein binding to form immunogenic adducts, resulting in direct cellular dysfunction or an immune response via the formation …

Temperature And Predator Effects On Green Crabs (Carcinus Maenas) And Their Distribution In South Slough National Estuarine Research Reserve, Elissa Connolly-Randazzo

Dissertations and Theses

The invasive green crab (Carcinus maenas) has increased in abundance and distribution among Oregon's estuaries. Its global success in establishing in new environments and tolerance for abiotic stressors, such as temperature, raises concern for C. maenas to negatively influence native crab species, especially given global climate change. To improve in predicting invasion impacts, this work analyzed the results from a controlled tank experiment at Portland State University and the field data on a population of C. maenas in South Slough National Estuarine Research Reserve (SSNERR). The aquarium experiment documented predation pressure on C. maenas across a range of …

The Impact Of New Light Rail Service On Employment Growth In Portland, Oregon, Lahar Santra

Dissertations and Theses

This study quantitatively examines the impact of the new Light Rail Transit (LRT) service on employment growth in retail, knowledge, and service sectors before and after opening the LRT. At the corridor level, this study conducts a case study of Greenline in Southeast Portland, Oregon. The results of the corridor level study suggest that the new LRT service increased employment along the Greenline corridor among all the three sectors of interest- retail, knowledge, service in the long-term (ten years) while having slightly different results for the short-term (five years), likely due to the slow growth of LRT benefits. This study …

Spatial And Seasonal Variations Of Microplastic Concentrations In Portland's Freshwater Ecosystems, Rebecca Talbot

Dissertations and Theses

Microplastics are a pollutant of growing concern and are ubiquitous in a variety of environmental compartments. The majority of microplastics research to date has been conducted in marine waters, and less is known regarding the sources and delivery pathways of microplastics in urban rivers. The first chapter is comprised of a review of the scientific literature regarding the spatial and temporal factors affecting global freshwater microplastic distributions and abundances. Microplastic spatial distributions are heavily influenced by anthropogenic factors, with higher concentrations reported in regions characterized by urban land cover, high population density, and wastewater treatment plant effluent. Temporal variables of …

Effects Of Green Crab (Carcinus Maenas) Across Variable Densities Of Eelgrass (Zostera Marina), Kimberly Alexis Brown

Dissertations and Theses

Eelgrass (Zostera marina) plays a critical role in estuarine ecosystem function by sustaining a variety of marine and freshwater species, but it's increasingly threatened by the aggressive non-native green crab (Carcinus maenas). The abundance of C. maenas is on the rise within the coastal environment of Oregon and it is imperative to know how these populations will affect the long-term health of Z. marina. C. maenas have been linked to declines in Z. marina coverage and shellfish abundance, but there has been no research on to what extent the density of Z. marina affects its …
