Medicare Advantage Dominance In Puerto Rico’S Healthcare System: Exploring Its Financial Landscape, Marketing Strategies And Quality Measures Using The Commercial Determinants Of Health Framework, Sergio Andrés Rivera-Rodríguez

Dissertations and Theses

Over time, Medicare Advantage (MA) has seen an increase in enrollment in the United States and Puerto Rico. This program, which is the privatized version of traditional Medicare, has faced critiques in recent years for being focused on profit maximization and reducing accessibility to Medicare beneficiaries. In Puerto Rico, the majority of Medicare beneficiaries (95%) choose a MA plan over traditional Medicare. Despite being the primary financier of healthcare in Puerto Rico and covering populations that require extensive healthcare services, individuals over 65 and those with disabilities, there are still numerous research gaps about the MA industry. This dissertation examines …

The Ecology Of Gender-Based Violence For Syrian Refugee Women In Tripoli And Akkar, Dima Masoud

Dissertations and Theses

Lebanon is a country that suffers from multiple economic, political, and health crises. Additionally, the mass displacement of Syrian refugees to Lebanon after the war in Syria over a decade ago has left Syrian refugees vulnerable, including the vulnerability of Syrian refugee women to gender-based violence (GBV). While these conditions have affected all of Lebanon, this dissertation focuses on the regions of Tripoli and Akkar in northern Lebanon. Tripoli and Akkar are regions that border Syria, which means that an influx of Syrian refugees, mostly unregistered, comes in. While other regions in Lebanon also border Syria, Tripoli and Akkar are …

Agglomeration Economies In Social Economy Clusters: The Role Of Networks, Mina Kim

Dissertations and Theses

The social economy is an economic framework that prioritizes social value over profit, emphasizing cooperation, solidarity, and community-based solutions to the failures of neoliberal market systems. In East Asia, the development of the social economy is often government-led, raising concerns about resource dependency and the long-term sustainability of Social Economy Organizations (SEOs). This dissertation investigates how network structures and diversity within a policy-driven social innovation cluster shape SEO survival, and how agglomeration economies operate differently compared to conventional industrial clusters. The case of Seoul Innovation Park (SI Park) in South Korea provides the empirical basis for the analysis.

A mixed-methods …

Exploring The Pathway From Customer Sexual Harassment To Instigated Incivility In Service Employees, Fernanda Wolburg Martinez

Dissertations and Theses

The current study explores how and why customer sexual harassment (CSH) experienced by service workers may lead to instigated incivility towards customers in the same week. Specifically, following the tenets of Personality Systems Interaction theory (PSI) and the affective shift model, I hypothesized that week-level affective shifts mediate this relationship, such that upshifts in anxiety and downshifts in self-assurance govern changes in motivational and cognitive functions that impair the employee's ability to provide good customer service. Further, supervisor preventive behaviors and psychological detachment are proposed as interventions that may lead to a departure from the mistreatment spiral by weakening the …

Pesticides As Multiple Stressors To Bivalves And Echinoderms, Alexandra Gabrielle Tissot

Dissertations and Theses

Pesticides are ubiquitous in aquatic environments, alongside numerous contaminants and other stressors that can result in combined exposure to target and non-target organisms. Nevertheless, traditional toxicity studies quantify the effects of these compounds at an individual level, and to a narrow range of traditional test organisms. Through this dissertation, I explored the presence and effects of commonly detected pesticides of concern in the Pacific Northwest in order to realistically quantify potential effects from combined stressors. In Chapter 2, I demonstrated my background knowledge on these select pesticides (atrazine, bifenthrin, diuron, indaziflam, and imidacloprid), including their chemical and physical properties. Using …

The purpose of this qualitative, self- study, autoethnography is to explore my instructional practices, strategies and decision making as I navigate my attempts to build a more anti-racist, racial justice social studies curriculum in a predominantly white school environment. Critical Race Theory as well as racial literacy provided me with a conceptual framework, but also with the language I need to articulate the research problem and my findings. Three research questions guided how I collected and analyzed my data: 1) How do I plan social studies lessons that address the topic of race/racism? 2) How can I use social studies …

Development Of A Low-Cost Electron Microscope For Educational Purposes, Christopher Halseth

Dissertations and Theses

Electron microscopy is a powerful tool for exploring microscopic world, yet its high cost and operational complexity severely limit accessibility, particularly within educational institutions. Commercial systems are often designed as opaque "black boxes," further hindering hands-on learning and experimentation. This dissertation introduces the Educational Scanning/Transmission Electron Microscope (EduSEM), a project designed to overcome these barriers by developing a low-cost, modular, and transparent electron microscope optimized for educational use.

The EduSEM achieves significant cost reduction by operating in a rough vacuum environment (1-20 mTorr), eliminating the need for expensive high-vacuum pumps. This necessitates novel component designs tolerant of higher pressures. The …

What This Work Really Takes: Lessons, Tensions, And Student Perspectives In A Social Justice Math Classroom, Kathryn Elizabeth Roman

Dissertations and Theses

In recent years, there have been growing calls for mathematics instruction that engages students in understanding and critiquing injustice through mathematics. While resources for social justice math (SJM) lessons have become increasingly available, implementing these lessons in real classrooms--with real students, real time constraints, and real pressures--remains a challenge. This dissertation explores how teachers and students navigate this complexity through three connected papers.

The first paper introduces a framework to support teachers and mathematics teacher educators (MTEs) in selecting and modifying pre-designed SJM lessons (PSJMLs). The framework is organized around three guiding principles: (1) center student identity and teacher self-awareness, …

Evaluation Of Social Worker Knowledge Of Human Trafficking At The Oregon State Hospital: A Qualitative And Quantitative Analysis Of Education, Training, And Victim Identification, Jamie Sue Pryde

Dissertations and Theses

The prevalence of human trafficking continues to increase worldwide, and the implementation of human trafficking education and victim identification within institutions is slow to catch up. The Oregon State Hospital is a psychiatric in-patient hospital that currently does not provide human trafficking education or a screening tool for staff and does not know how to provide treatment to trafficked victims. Interviews were conducted with employed social workers at the Oregon State Hospital to obtain a baseline understanding of their previous education, training, and knowledge of human trafficking to aid in the creation of a trafficking screening tool. Results indicate participants …

Is Ride-Hailing A Potential Solution For Older Adults After Driving Cessation? The Role Of Objective And Perceived Accessibility, Minju Kim Song

Dissertations and Theses

Due to age-related physical and cognitive changes, older drivers have a greater risk of crashes and are restricted by age-dependent regulation. Nonetheless, many older adults in the United States maintain a car-dependent lifestyle and still prefer driving. When driving cessation or reduction becomes necessary, a primary concern is finding suitable alternative transportation modes. However, the availability of alternative transportation modes does not guarantee their actual use of these options.

As a relatively new transportation mode, ride-hailing services, such as Uber and Lyft, offer on-demand, door-to-door transportation and may be a feasible transportation solution for older adults who stop driving. While …

#Clandestini: How Italy's Center-Right Parliamentary Coalition Frames The Migrant Crisis On Social Media, Jenna Lynn Depasquale

Dissertations and Theses

This dissertation examines the intersection of Italian neo-fascism, the Mediterranean migrant crisis, and digital media. Through a qualitative content analysis of the Twitter and Instagram posts made by Italy's center-right parliamentary coalition from 2014-2018, this research outlines frameworks that facilitate both the physical and social deaths of migrants. Twitter is a platform on which bite-sized xenophobic messages characterize migrants as criminals, spoiled youth, spreaders of infectious disease, and future terrorists--sometimes in a contradictory fashion. Instagram is a medium for conveying Italian identity and history, which disregards the longstanding contributions of people of color, including Muslims, in Southern Italy. Comment sections …

How Do Health Insurer Practices Affect Health Equity For Gay And Bisexual Men And Transmasculine Individuals? A Qualitative And Health Policy Assessment, Alexa D'Angelo

Dissertations and Theses

In the U.S. there continue to be stark disparities in health that affect LGBTQ+ communities. These disparities include those related to mental health, sexually transmitted infections, along with chronic illnesses and some cancers. Higher health needs across diagnostic categories mean that LGBTQ+ individuals require access to the healthcare system both to prevent conditions disproportionately affecting the community, and to treat conditions as they arise. In the U.S., access to healthcare often requires either reliable insurance coverage or another payer to cover costs associated with care. Thus, health insurance status and coverage of care, along with coverage regulations and health policies …

Price-Signal-Based Control Strategy For Heat Pump Water Heaters In Demand Response Applications, Othman A. Murad

Dissertations and Theses

This work presents a price-signal-based control strategy for residential Heat Pump Water Heaters (HPWHs) aimed at reducing electricity costs and shifting load away from high-price periods. By integrating the California Load Flexibility Research and Development Hub (CalFlexHub) prototype price signals, the Consumer Technology Association (CTA-2045-B) communication protocol, and the Object-oriented, Controllable, High-resolution Residential Energy (OCHRE) simulation framework, a rule-based controller was developed to align HPWH operation with dynamic electricity pricing while maintaining hot water availability.

The control strategy was evaluated through two case studies: one using a fixed water draw profile under varying levels of price signal foresight, and another …

"We're Not Gonna Take It": The Parents' Music Resource Center And Reformist Tendencies In American Society, Nathaniel Todd Belcik

Dissertations and Theses

The Parent's Music Resource Center is a cultural curiosity that few historians have examined. Started by Tipper Gore and Susan Baker, the wives of prominent politicians, they advocated for a warning label on music with explicit lyrics and achieved their goal within only a few years of their creation. This thesis aims to contextualize the PMRC within a broader context of middle-to-upper class reformist movements. Many have argued that the PMRC falls on the conservative end of the political spectrum. Yet, a more complete story can be told by situating the organization within a reformist tendency in American history, thus …

Influencing Factors Of Angle-Of-Arrival Estimator Based On Deep Learning, Guohao Pang

Dissertations and Theses

Deep learning (DL)-based angle-of-arrival (AoA) estimation offers significant advantages over traditional signal processing methods, especially in complex and high-noise environments. However, situational complexity and differences in hardware can significantly impact the estimator's performance. It is therefore of interest to investigate the relationship between the performance of deep learning models and the variation of physical parameters such as the number of signal sources, the number of receiving antennas, and the signal-to-noise ratio (SNR). In this study, we investigate the impact of these variations on deep learning-based AoA estimation by systematically analyzing how the variations in the characteristics of the received signal …

Their Will Is Wealth: American Billionaires, Illiberal Capital, And Their Immunity To Federal Law, Conor Kawika Carroll

Dissertations and Theses

Billionaires are inherently unique political actors. They, and their wealth, are a species apart. This rarity is measurable by quantifying relative consequences for actions made on behalf of that wealth. This thesis explores whether or not a billionaire's political power provides them with immunity to federal laws and regulations that govern wealth and its political use. The objective of this research is two-fold: to illustrate the scholarship gap regarding American billionaires and their relative immunity from federal law, and to instigate academia to study billionaires politically at increasing rates, providing more data for lawmakers regarding the most economically powerful political …

The first study analyzes GSS data to examine the impact of the #MeToo movement on self-reports of sexual harassment and gender discrimination. Results show an increase in reporting sexual harassment among White men and Women of color. With respect to men of color and white women, the results were not significant or did not show an increase. …

The Failure Of The Annan Plan And Suggestions For Peace In Cyprus, Haley Grace Morrow

Dissertations and Theses

The following study explicates the conflict in Cyprus between the Greek Cypriots and the Turkish Cypriots. The conflict began around 70 years ago and came to its height in the 1970s when a Greek coup occurred, and subsequently, Turkey invaded the northern part of the island. This drove the two parties apart physically and mentally. The Annan Plan, a UN peace plan in 2004, attempted to bring peace to the island by reunifying the two parties into a bi-communal federation. However, this plan failed as the Greek Cypriots voted against it. The failure of the plan was primarily due to …

Navigating Sovereignty And Human Rights: A Legal Analysis Of Palestinian Detention Under Israeli Jurisdiction In Comparison To International Law, Amani Nidal Odeh

Dissertations and Theses

This thesis examines whether Israeli detention practices of Palestinians conform to or contravene Israeli domestic legislation and international legal standards using a doctrinal legal analysis. This thesis evaluates six key areas through four hypotheses: the detention of minors, geographic disparities (particularly Gaza), administrative detention procedures, the use of military courts, due process violations, and detention conditions. While Israeli domestic law formally authorizes these practices, the analysis finds they routinely violate crucial international legal norms, including the ICCPR, CRC, CAT, and the Fourth Geneva Convention. The use of secret evidence, prolonged administrative detention without trial, and discriminatory legal frameworks undermines the …

"I'M Strictly T4t": Trans For Trans Connections In The Contemporary, Madi Lou Alexander

Dissertations and Theses

Trans for trans relationships, referred to as "t4t", are a relationship type specific to trans individuals. Linguistically originating from Craigslist personal ad spaces, t4t indicates a trans person seeking out and engaging with another trans person. The scope of relationships under the t4t label are often largely associated with sexuality and dating scenes due to their conception in online cruising spaces. Through qualitative analysis, I assess the range of what t4t relationships are through 30 in-depth interviews with participants identifying as trans. This work moves away from focusing on the deficits of holding a marginalized identity, instead aiming to center …

Beyond Skins: The Far-Flung Impacts Of Sea Otter Fur Capitalism, Callie Pappas

Retention Intervention Program Success: An Inquiry Into Learning Organization Structural And Cultural Elements In California Community Colleges, Paul Vernon Wickline

Dissertations and Theses

Community colleges serve a diverse, underrepresented, and economically disadvantaged student population, yet most students fail to complete their academic goals, with students from marginalized groups facing even more significant disparities. Some colleges have implemented Early Alert and Intervention (EA&I) programs to improve retention and completion rates. However, colleges may face organizational challenges in implementing and sustaining these retention programs. This qualitative study examined structural and cultural elements in community colleges that have successfully implemented EA&I programs, focusing on student services and student affairs practices that support a learning-centered environment. Findings suggest that effective EA&I programs are grounded in inclusive, collaborative, …

The Role Of Cultural Mathematical Caring Relations In Supporting Two Latina Undergraduates’ Rate Of Change Development Within A Constructivist Teaching Experiment: An Anti-Deficit Investigation Bridging Sensemaking And Cultural Experiences, Christopher Orlando Roman

Dissertations and Theses

This study introduces cultural mathematical caring relations (CMCRs) as a framework that extends Hackenberg's mathematical caring relations by integrating two tenets of culturally relevant pedagogy: academic achievement and cultural competence. Framed within radical constructivism, CMCRs prioritize students' cognitive growth and development while affirming their cultural and experiential identities by embedding their funds of knowledge into the learning process. Through a constructivist teaching experiment with two Latina students, Yari and Jocelyn, this research investigates how working to establish and maintain CMCRs can influence Latin* students' rate of change development.

Findings illustrate that CMCRs supported the development of Yari and Jocelyn's rate …

This dissertation focuses on the enhancement and optimization of frequency event detection algorithms. These …

The Effects Of Family Cohesion On The Relationship Between Trauma And State-Level Social Policy Provision In The United States, Brandon Kendall Ross Fielding

Dissertations and Theses

This dissertation examines how childhood trauma and family cohesion interact to shape state-level social policy generosity in the United States. The study begins with a multilevel quantitative analysis using data from the National Survey of Children’s Health and the State Safety-Net Generosity Index to assess how individual-level experiences of trauma and family support relate to state-level welfare generosity. Two trauma indices--one focused on adverse childhood experiences and bullying, and the other on food-related hardship--are used to explore how trauma influences attitudes toward public assistance, and whether family cohesion moderates this relationship. Results from marginal effects analyses indicate that family cohesion, …
