Reconstruct, Jenna Deal

Theses

This thesis explores how construction materials can be used in sculpture, pushing artistic boundaries and challenging traditional perceptions. It examines the potential of materials like mortar, PVC, HVAC duct, carpet, and asphalt roofing, aiming to redefine the relationship between labor, materials, and artistic expression. By breaking free from construction norms and engaging with materials in unexpected ways, the study aims to foster a deeper understanding of the value and creative possibilities inherent in the materials of our built environment.

Review Of Literature On Efficacy And Safety Of Birthing Positions With Emphasis On International Cultural Influences On Obstetric Care, Ava E. Retsch

Theses

• Background: When examining most non-Westernized societies, parturients hold all the power in the birthing space with traditional birth attendants and medical staff serving as guiding forces and protectors, not directors of the process. Social media in Western countries is filled with stories from birthing people who felt unsupported, ignored, or discriminated against by their healthcare providers; this is particularly prevalent in parturients who express a preference for non-supine birthing positions. Methods: This work is a review of the existing body of literature on quantitative and qualitative outcome measures of alternative birthing positions. In total, 44 articles were analyzed …

The Impact Of Banning Confidential Settlements On Discrimination Dispute Resolutio, Blair D. Bullock, Joni Hersch -- Cornelius Vanderbilt Professor Of Law And Economics

Vanderbilt Law Review

The #MeToo movement exposed how workplace harassment plagues employment in the United States. Several states responded by passing legislation aimed at curbing harassment and employment discrimination in the workplace. One of the most common legislative efforts was to ban confidentiality provisions in certain settlement agreements. These bans, in part, attempted to stop "secret settlements" by shining light on workplace discrimination and exposing serial harassers as a means to motivate firms to actively deter workplace discrimination.

But do bans on confidentiality agreements deter the bad act? For these laws to have a deterrent effect, claims must be revealed in a public …

Access To Justice For Black Inventors, Jordana R. Goodman, Khamal Patterson

Vanderbilt Law Review

To receive a patent, an inventor must meet certain inventive and procedural standards. Their invention must be novel, nonobvious, and written in such a way that any person skilled in the inventive subject can make and use the invention without undue experimentation. This process is far from objective.

An inventor is not always communicating within their own social circle. An inventor is required to communicate their invention so that a patent examiner believes a person having ordinary skill in the art ("PHOSITA") would recognize the invention as nonobvious. Moreover, a fictitious skilled person must be able to make and use …

Examining The Multifaceted Impacts Of Drug Decriminalization On Public Safety, Law Enforcement, And Prosecutorial Discretion, Kelsey S. Henderson, Christopher M. Campbell, Brian C. Renauer

Criminology and Criminal Justice Faculty Publications and Presentations

This final report provides the findings of a multi-year project to understand the effects of successive drug policy efforts in Oregon. Since 2013, Oregon has implemented three changes that reclassified and lowered the seriousness of low-level drug possession offenses, with multiple years between each policy change: Justice Reinvestment in 2013, defelonization in 2017, and decriminalization in 2021. This project parses out the individual impacts of these unique events on law enforcement, prosecution, courts and sentencing, and public safety & health.

The Uae’S Readiness For Technology Export: The Case Of Ai, Reem Tamer Aldandashi

Theses

Export diversification is one way for the UAE to sustain and flourish its economy. Although UAE is an oil-rich country, it needs to search for and incubate future exports besides the existing ones to keep the wheel of the economy moving, increase the employment rate, and strengthen the country from any future economic strokes. While looking at the technology spread and Artificial Intelligence (AI) focus and efforts in UAE, much research investigated the outcomes of digitization on the UAE economy and its technological strength and competitiveness.

Is It Possible For Glp-1ras To Combat Type 2 Diabetes And Its Comorbidities?, Michael Weingarten

The Science Journal of the Lander College of Arts and Sciences

Type 2 Diabetes Mellitus is a prevalent metabolic disorder characterized by insulin resistance and pancreatic beta-cell dysfunction, leading to chronic hyperglycemia and comorbidities such as obesity and cardiovascular disease. Traditional treatments focus on glycemic control, but often fail to address the broader spectrum of related conditions. This study investigates the potential of glucagon-like peptide-1 receptor agonists (GLP-1RAs) to combat type 2 diabetes and its comorbidities through their diverse mechanisms of action. GLP-1RAs not only improve glycemic control by enhancing insulin secretion and inhibiting glucagon release, but also promote weight loss, reduce inflammation, and lower cardiovascular risk. The efficacy of GLP-1RAs …

Overview Of Weight Loss Medications, Malky Mandel

The Science Journal of the Lander College of Arts and Sciences

Obesity is a complex medical condition that is multifactorial in origin. About one-third of adults in the United States are obese, and another third are overweight (Ogden et al., 2007). Obesity is associated with a multitude of comorbidities, such as cardiovascular disease, diabetes mellitus, and osteoarthritis (Lim, Boster, 2023). Additionally, obesity may cause psychological disorders due to social prejudice and discrimination toward obese people (Wadden et al. 2002). Economically, obesity is also a tremendous financial burden (Tremmel et al. 2017). It is estimated that the overall cost of obesity-related illness in the US is nearly $500 billion (Cawley et al., …

Who Bears The Burden When Prison Guards Rape?, Meredith B. Esser

Scholarly Works

Several recent scandals have highlighted the continued problem of institutional sexual abuse within the federal Bureau of Prisons ("BOP"). Most notoriously, the rampant sexual abuse of women incarcerated at Federal Correctional Institution ("FCI") Dublin, also known as the "rape club," resulted in the prosecution and conviction of several high-ranking officials within FCI Dublin, including both the former Warden and former Chaplain who worked there for several years. In response to these patterns of misconduct, the Federal Sentencing Commission's new guidelines, which went into effect on November 1, 2023, now allow for victims of custodial sexual assault to apply for early …

Religious Accommodations In The Dobbs Era, Ann C. Mcginley

Scholarly Works

Given the deep political divide in the U.S. and the emotional response to the abortion issue, workplaces may become hostile environments that harm workers based on their pro- or anti-abortion views or their out-of-work activism. Besides hostile environments, some workers may suffer workplace discipline based on their speech at work or refusals to engage in certain job requirements. Disciplining employees for engaging in workplace speech or refusal to perform parts of their jobs may violate workers’ rights under Title VII of the Civil Rights Act of 1964, which requires that employers grant religious accommodations in the workplace if doing so …

Deep Adaptive Graph Clustering Via Von Mises-Fisher Distributions, Pengfei Wang, Daqing Wu, Chong Chen, Kunpeng Liu, Yanjie Fu, Jianqiang Huang, Yuanchun Zhou, Jianfeng Zhan, Xiansheng Hua

Computer Science Faculty Publications and Presentations

Graph clustering has been a hot research topic and is widely used in many fields, such as community detection in social networks. Lots of works combining auto-encoder and graph neural networks have been applied to clustering tasks by utilizing node attributes and graph structure. These works usually assumed the inherent parameters (i.e., size and variance) of different clusters in the latent embedding space are homogeneous, and hence the assigned probability is monotonous over the Euclidean distance between node embeddings and centroids. Unfortunately, this assumption usually does not hold since the size and concentration of different clusters can be quite different, …

Assessing The Acceptability And Effectiveness Of A Novel Therapeutic Footwear In Reducing Foot Pain And Improving Function Among Older Adults: A Crossover Randomized Controlled Trial, M G Finco, Abderrahman Ouattas, Nesreen El-Refaei, Anmol Salim Momin, Mehrnaz Azarian, Bijan Najafi

Center on Aging Staff Publications

Introduction: Nearly, a quarter of older adults suffer from frequent foot pain, impacting their quality of life. While proper footwear can alleviate this, design issues often hinder regular use. This study evaluated novel therapeutic footwear, designed for aesthetics and custom fit, to reduce foot pain. We hypothesized that older adults would experience less foot pain and favor the new footwear over their own.

Methods: This 12-week crossover randomized controlled trial evaluated the effectiveness of OrthoFeet therapeutic footwear on reducing foot pain in older adults (n = 50, age = 65 ± 5, 18% male) with moderate to severe pain. Participants …

Structural And Magnetic Properties Of Molecular Beam Epitaxy (Mnsb2te4)X(Sb2te3)1−X Topological Materials With Exceedingly High Curie Temperature, Candice R. Forrester, Christophe Testelin, Kaushini Wickramasinghe, Ido Levy, Dominique Demaille, David Hrabovsky, Xiaxin Ding, Lisa Krusin-Elbaum, Gustavo Lopez, Maria C. Tamargo

Publications and Research

Tuning the properties of magnetic topological materials is of interest to realize exotic physical phenomena, new quantum phases and quasiparticles, and topological spintronic devices. However, current topological materials exhibit Curie temperature (T_C) values far below those needed for practical applications. In recent years, significant progress has been made to control and optimize T_C, particularly through defect-engineering of these structures. Most recently, we reported T_C values up to 80 K for (MnSb₂Te₄)_x(Sb₂Te₃)_1−x when 0.7 ≤ x ≤ 0.85 by controlling the composition x and the …

Time-Efficient Filtering Of Imaging Polarimetric Data By Checking Physical Realizability Of Experimental Mueller Matrices, Tatiana Novikova, Alexey Ovchinnikov, Gleb Pogudin, Jessica C. Ramella-Roman

Publications and Research

Motivation: Imaging Mueller polarimetry has already proved its potential for biomedicine, remote sensing, and metrology. The real-time applications of this modality require both video rate image acquisition and fast data post-processing algorithms. First, one must check the physical realizability of the experimental Mueller matrices in order to filter out non-physical data, i.e. to test the positive semi-definiteness of the 4 × 4 Hermitian coherency matrix calculated from the elements of corresponding Mueller matrix pixel-wise. For this purpose, we compared the execution time for the calculations of (i) eigenvalues, (ii) Cholesky decomposition, (iii) Sylvester’s criterion, and (iv) coefficients of the characteristic …

It’S About Time, Part Ii: Does Time Poverty Contribute To Inequitable College Outcomes By Gender And Race/Ethnicity?, Claire Wladis, Alyse C. Hachey, Katherine M. Conway

Publications and Research

Existing research demonstrates gender- and race/ethnicity-based inequities in college outcomes. Separately, recent research suggests a relationship between time poverty and college outcomes for student parents and online students. However, to date, no studies have empirically explored whether differential access to time as a resource for college may explain differential outcomes by gender or race/ethnicity. To address this, this study explored the relationship between time poverty, gender or race/ethnicity, and college outcomes at a large urban public university with two and four year campuses. Time poverty explained a significant proportion of differential outcomes (retention and credit accumulation) by gender and race/ethnicity. …

Grid Culture, Eliot Bates, Arseni Troitski

Publications and Research

In this essay, we provide our initial ethnographic research about lines, which at a superficial level can be considered a platform, but which is also synonymous with a community of 8800 users, and with 606k unique posts authored by these users that in aggregate constitute a discourse network (Aufschreibesysteme, see Kittler 1990). lines—as platform, community, and discourse network—is primarily designed to support the development, documentation and user-generated code efforts specific to a set of hardware synthesis-related objects (the two we will focus on are called Norns and Grid; we’ll discuss what they are and what they do through the subsequent …

Assembling Hyperpop: Genre Formation On Wikipedia, Eliot Bates, Sophie Delphis, Romulo Moraes, Julia Santoli

Publications and Research

In this article, we analyze how a music genre is reciprocally defined online, through the crowdsourced ‘facts’ of Wikipedia. What are the traditional implicit and explicit exclusionary practices in this sort of genre formation? And how can internet-specific sociabilities create new exclusionary practices in the process of defining music? By analyzing the edit history of Wikipedia’s ‘hyperpop’ page, we locate ongoing debates, controversies, and contestations that point to shaping forces around online genre formation. These potentially have a huge impact on how hyperpop is understood both inside and outside of the music community. In locating the most active editors of …

Fight, Flight, Freeze: How Access To Support Shapes Tenant Responses To Eviction In Multnomah County, Natalie J. Cholula, Lisa K. Bates, Alex Farrington, Marisa Zapata, Colleen Carroll, Jacen Greene, Hadley Bates

Urban Studies and Planning Faculty Publications and Presentations

Facing eviction is a traumatic event that forces tenants into a fight, flight or freeze response. Our focus groups with Multnomah County tenants reveal that their responses to eviction are directly shaped by their access to support. Many tenants are unable to access formal support and therefore respond to eviction by freezing up or fleeing their home. Conversely, tenants who can access formal support—including rental assistance or legal assistance—exhibit a fight response, leveraging external support to challenge or avoid their eviction.

Shame And History, Bennett B. Gilbert

University Studies Faculty Publications and Presentations

If history—our past, the sum of our thoughts, passions, and deeds—is so pervasive, influential, and meaningful, why then do we lose sight of it? Why do we not gain good values from it? And if it is part of our existential core, why then do we so often fail to ravel it into our deliberations?

I propose that very often and to a great degree it is shame that separates us from history. Shame: garrulous, compulsive, intense, omnivorous. A shamed person pushes away the experiences that shame her, thus cutting off the past.

Impacts Of Sex Work Criminalization On Sex Workers In Oregon: A Pilot Study, Stephanie Wahab, Katie Shammel

School of Social Work Faculty Publications and Presentations

Executive Summary

Context for the Study
In July, 2023, Oregon legislators voted to fund research exploring the impacts of the criminalization of sex work in Oregon. Unfortunately, the Governor vetoed the budget item, stating that the private sector should fund this type of public health research and noting the need for additional public discussion about the issue. To date, there have been no attempts to study the impacts of prostitution laws on the people most impacted by them in Oregon. The research presented in this report seeks to address this gap.

This qualitative pilot study was designed to better understand …
