Essays In Health Economics, Chuxin Liu

Dissertations, Theses, and Capstone Projects

In Chapter 1, I investigate the effect of a financial incentive from the Centers for Medicare and Medicaid Services (CMS) on new medical procedure technology diffusion. I examine how the incentive affects diffusion among Medicare patients, for whom hospitals receive the incentives, and non-Medicare patients for whom there are no incentives. I answer these two questions by studying the New Technology Add-on Payment (NTAP) program offered by Medicare (Part A). It is unknown whether its incentive is enough to encourage diffusion under the prospective payment system and it also remains unknown whether it spills over to non-Medicare patients or crowds …

Parallel Processes Of Posttraumatic Stress And Metabolic Dysfunction: Long-Term Costs Of Trauma On The Psychological And Physical Health Of 9/11 Survivors, Shane W. Adams

Dissertations, Theses, and Capstone Projects

Metabolic conditions (MetC) have been associated with posttraumatic stress disorder (PTSD) symptoms and may be critical indicators of the systemic physical sequelae of traumatic stress. Parallel process latent growth modeling wasapplied to longitudinal data collected from 35,788 9/11 survivors and used to model PTSD symptoms and MetC to determine how the development and course of one affect the other. A unidirectional relationship was found in which the intercept of PTSD symptoms predicted the slope of MetC. Hyperarousal (ß=.172) and emotional numbing (ß=.171) PTSD symptoms demonstrated the strongest association with the growth of MetC over and above …

The Relationship Between “Black Lives Matter” Movement Protests And Police Arrests In New York City, Chicago, And Los Angeles: An Empirical Analysis, Lukas Louwagie

Dissertations, Theses, and Capstone Projects

The summer of 2020 marked a boiling point of protest and frustration at long-criticized police behavior in the United States. The events that summer revealed the “Black Lives Matter” (BLM) movement as something that could not be ignored and was capable of drawing national support and attention across many dividing lines (Mitchell 2020). Today, it seems evident that the BLM movement has had a substantial impact on modern political discourse—yet its impact on police behavior and reform, the primary target of the movement, is murky. Police departments across the nation are pushing back against calls to defund and reform their …

Representaciones Ideológicas Del Lenguaje Entre La Población Mexicana En Nueva York, Maria Del Rocio Carranza Brito

Dissertations, Theses, and Capstone Projects

The purpose of this dissertation is to explore the linguistic ideologies that Mexican migrants bring when migrating and reproduce in their daily interactions with other Spanish and English speakers, as well as the representations of the language presented in their linguistic behaviors. This work presents an intersectional analysis where the factors of gender, migratory status, education, and work are determining factors in the adoption, maintenance, and reproduction of language ideologies, which affect the linguistic decisions of the speakers in their use of Spanish, learning of English and the support of bilingualism. Based on the stereotypical idea of Spanish as the …

Burnout And Depression In Teachers And Members Of Other Occupational Groups: A Systematic Review And Meta-Analyses On Potentially Overlapping Conditions, Gail Swingler

Dissertations, Theses, and Capstone Projects

Burnout has long been recognized as a workplace issue among teachers, and other occupational groups. Burnout has potentially been increasing during the Covid-19 pandemic. Researchers tend to regard burnout as a distinct syndrome comprising emotional exhaustion (EE), depersonalization (DP), and reduced personal accomplishment (rPA). Recent evidence suggests that burnout (as a tripartite syndrome) lacks discriminant validity vis-à-vis depression. The overlap between burnout and depression was examined through two meta-analytic studies.

The first study (K = 13) examined the relationship between burnout and depression in teachers with burnout assessed using the MBI. The findings indicated that exhaustion (EE), and depression …

Artists, Activists, And Therapists Making Meaning Of Collective Violence In Lebanon: A Community-Engaged Participatory Research Study, Nawal Muradwij

Dissertations, Theses, and Capstone Projects

This study collaborated with community-engaged artists, activists, and mental health workers living in Lebanon to explore the community narratives that exist around collective violence in Lebanon. With the support of a community advisory board, in-depth interviews, and focus groups were utilized to understand the associations that participants had with the construct of collective violence as it pertains to communities in Lebanon and their understanding of its impact on collective mental health. The sample of artists, activists, and mental health workers framed collective violence in Lebanon as intergenerational, perpetual, and institutionally and politically entrenched. Cultural concepts that described the impact of …

Variations In Family Child Care: Providers' Experiences Crafting Spaces In-Between School And Home, Eleanor Luken

Dissertations, Theses, and Capstone Projects

Family child care, which takes place in the caregiver’s own home, is one of the most common arrangements for American working parents, yet it remains low paid and undervalued in the ecosystem of early childhood care and education (Uttal and Tuominen, 1999). Little is known about how family child care providers organize space within their homes and the repercussions the location of care has on their daily practices with children, relationships with family members, and design of their homes. Even less is known about the strategies used by providers operating in dense, urban neighborhoods with high housing costs. This investigation …

"How" As A Signal Of An Invariant Meaning, Andrew S. Mccormick

Dissertations, Theses, and Capstone Projects

This dissertation aims to explain why speakers and writers use how in the communicative contexts in which they do, and its central claim is that how is a signal of one invariant meaning. The form’s diverse communicative contributions can be explained by hypothesizing a single meaning that contributes to different message effects, or contextual interpretations, on different occasions of its use.

The present analysis rests on the crucial distinction in Columbia School (CS) linguistics, the theoretical framework guiding this project, between meaning and message. A meaning is a signal’s invariant semantic contribution, while messages are the context-unique interpretations that …

Quality Management And Oversight Of Texas Forensic Science Service Providers, Sarah P. Chu

Dissertations, Theses, and Capstone Projects

Forensic science oversight in the U.S. largely relies upon voluntary third-party forensic laboratory accreditation programs. Without a national system of regulation and given the highly fragmented local systems of control, few forensic science service providers (FSSPs) are subject to regulatory oversight beyond their third-party accreditors. Texas is unique in its establishment of a robust statewide oversight system and a strong governmental culture of transparency, permitting this study of forensic quality management. This study consisted of two parts. The first part of this dissertation characterized and analyzed quality incident reports (QIRs) published by the Texas Department of Public Safety Crime Laboratory …

Examining The Prevalence And Psychopathological Correlates Of Paraphilic Interests In A Non-Clinical Sample, Dylan H. Abrams

Dissertations, Theses, and Capstone Projects

The paraphilias are among the most contentious diagnoses in contemporary psychological discourse. One of the major debates is over the extent to which paraphilic interests and behaviors should be considered “deviant.” To address this issue, extant research has examined the prevalence of paraphilic interests and their correlation with psychopathology. Though findings suggest that certain paraphilic interests are relatively common, existing data may misrepresent true prevalence rates due to racially and ethnically homogenous sampling. Additionally, though an association between paraphilias and psychopathology has been found in forensic and clinical samples, this relation may not generalize to all individuals with paraphilic interests. …

Grand Strategy At The End Of History: Chinese Strategic Thought In The 21st Century And Its Western Perceptions, Daniel A. Rogers

Dissertations, Theses, and Capstone Projects

Too often does the study of grand strategy, especially as it is conducted by academics based in the United States, take on an ethnocentric perspective which would lead American audiences to believe it is their country alone which possesses a coherent grand strategy that seeks to secure the national interest and nothing more. This chauvinistic approach not only leaves the majority of the world out of the conversation of grand strategy, but also results in the characterizing of the strategic approaches of non-Western states as disruptors of the foreign policy goals of the United States. The People’s Republic of China …

Bargaining In The Shadow Of The Truth: How Client Assertion, Perception Of Guilt, And Predictive Inaccuracy Influence Plea Recommendations, Anna D. Vaynman

Dissertations, Theses, and Capstone Projects

Over the past few decades, the largely hidden, secretive, and widely used system of plea bargaining has caught the fervent attention of scholars. The Shadow of the Trial model has been central to much of the plea-bargaining literature, despite significant critiques about its oversimplification. The model posits that defendants and their attorneys make plea decisions based largely on the estimated probability of conviction and the severity of the sentence to which the defendant could be exposed at trial.

The model, however, assumes that all actors are rational, equally risk averse, have no competing interests, and possess high predictive accuracy. It …

Applying Structural Equation Modeling To Better Understand The Relationship Between Stressors, Social Support And Wellbeing In The Lives Of Spouse Dementia Caregivers, Craig Holden

Dissertations, Theses, and Capstone Projects

Applying Structural Equation Modeling to Better Understand the Relationship Between Stressors, Social Support and Wellbeing in the Lives of Spouse Dementia Caregivers considers the utility of Pearlin et al.’s (1990) stress process model in understanding the needs of spouse caregivers. Data were drawn from eight biennial waves of the University of Michigan Health and Retirement Study (HRS) and analyzed using structural equation modeling. The final study sample comprised 774 spouses, average age 73, who were categorized based on Alzheimer’s Disease and Related Dementia (ADRD) and non-ADRD caregiver status. Results showed that for the study sample as a whole, social support …

Wanting Under Surveillance: A Critical Analysis Of Young Women’S Sexual Desire, Jennifer Chmielewski

Dissertations, Theses, and Capstone Projects

The negotiation of sexual desire is argued to be a vital part of the development of women’s sense of agency and well-being. Whereas desire is a concept that is widely used, measured, and diagnosed, women’s experiences of desire are poorly understood. Heeding the calls of feminist psychologists for conceptual analysis, and the need to examine desire within the multiple intimate and sociopolitical contexts in which sexuality develops, my dissertation is a critical feminist analysis of young women’s desire, centered on their subjective and embodied experiences. Moving beyond questions of what women desire or how much desire they have, I explore …

Colonial Geographies Of Gendered Violence And Mental Health In The United States And Puerto Rico, Lorraine Lizbeth L. Torres Colon

Dissertations, Theses, and Capstone Projects

As of January 2021, after years of community organizing and protests, the Puerto Rican island government announced a state of emergency due to the high rates of gendered violence on the island. At the same time, within the field of psychiatric epidemiology, consistent findings have indicated higher frequencies of mood disorders and substance abuse disorders among Puerto Ricans both on and off the island, relative to all other US Latinx ethnic groups. This dissertation frames Puerto Ricans experiences with psychological distress and gendered violence as public health issues nested within differing geographies of colonial divestment. I explore the relationships between …

Extreme E-Service Learning: Remote Learning For Undergraduate Students And Telehealth Intervention For Children With Autism, Madiha S. Muzammal

Dissertations, Theses, and Capstone Projects

Extreme e-service learning courses in higher education, in which all components of the course including the instruction and service is provided online (Waldenr et al., 2012), offer rich educational experience as well as mutual benefits to the students, community and the higher education institutes. Very few studies have examined extreme e-service learning. We examined an undergraduate extreme e-service learning course in psychology; students learned through a virtual class and provided telehealth behavioral intervention services to children with Autism Spectrum Disorder (ASD). Utilizing mixed methods (quantitative and qualitative measures including student observations, assignments, and self-reports) and a mixed design (single subject …

Africa’S Coastal Archaeological Record And Climate Change, Michael Murphy

Dissertations, Theses, and Capstone Projects

Since the 1980s, archaeologists have warned about threats from anthropogenic climate change (ACC) to the world’s archaeological record in coastal areas. Until recently, such warnings did not include Africa’s archaeological record. There is a persistent gap in research on climate change and Africa’s archaeological and cultural heritage stretching back before the U.N. established the Inter-governmental Panel on Climate Change (IPCC) in 1988. The purpose of this thesis is to assess the gap and help to narrow it. The approach is to take advantage of the availability of the dataset from the first geographically comprehensive study of climate change and coastal …

Evocative Visualization Of Void And Fluidity, Tomiko Karino

Dissertations, Theses, and Capstone Projects

In the last few years alone, we have seen a significant increase in a demand for inclusion and diversity in every sector in our society. While there are numerous data visualization projects that point out and raise concerns about the lack of diversity, they often merely illustrate the disparity. By using the permanent collection data of the Museum of Modern Art, this capstone project explores ways to creatively visualize gender disparity among the artists in the museum’s collection and questions what makes evocative visualizations that make an impression on the audience. It examines how to create visualizations that not only …

A Blackgirl Artivisionary Mosaic: Art-Based Participatory Refusals To School Punishment, Tyese A. Brown

Dissertations, Theses, and Capstone Projects

The study participants were co-research partners and engaged in a Project Based Learning six-week summer project in an urban northeastern metropolis community-based non-profit where they received stipends for participation. This dissertation explored how Blackgirls (aged 14 -21) express their experiences with disparate school punishment through community-based participatory artmaking. We called the photos, poems, collages, sculptures, storyboards, digital art, visual art, songs, spoken word, and videos Artivisions (art I vision). In the Jam Sessions, a subset of the partners we called curators discussed the pieces, shared their experiences, and offered insight into Blackgirls’ responses, coping skills, and decision-making regarding school punishment. …

Towards Interpretable Machine Reading Comprehension With Mixed Effects Regression And Exploratory Prompt Analysis, Luca Del Signore

Dissertations, Theses, and Capstone Projects

We investigate the properties of natural language prompts that determine their difficulty in machine reading comprehension tasks. While much work has been done benchmarking language model performance at the task level, there is considerably less literature focused on how individual task items can contribute to interpretable evaluations of natural language understanding. Such work is essential to deepening our understanding of language models and ensuring their responsible use as a key tool in human machine communication. We perform an in depth mixed effects analysis on the behavior of three major generative language models, comparing their performance on a large reading comprehension …

The Effects Of Isolated Affordances On Preschool Counting Improvement When Using A Digital Coloring App, Katherine Papazian

Dissertations, Theses, and Capstone Projects

Counting is an important preschool math skill that is necessary for building a strong foundation in mathematics. Previous research has demonstrated that guided counting activities can improve counting ability in preschoolers and that drawing on paper while learning can deepen processing, but research has not included digital drawing as a potential means of deepening processing while children count. This study developed a novel touch-screen app, which used a guided coloring activity to encourage effective counting skills and serve as a home numeracy tool that could be employed by all parents, including those with math anxiety. To evaluate the benefits of …

Redrawing The Contours Of Care: Ethical Commitments And Gendered Politics In The Work Of Government Psychological Counsellors In Sri Lanka, Nadia Augustyniak

Dissertations, Theses, and Capstone Projects

Over the last three decades, Sri Lanka has seen a growing popular interest in psychology as a field of professional practice as well as a steady expansion of mental health services. Historically, this shift has been linked to the impacts of political violence (1971, 1987-1989), civil war (1983-2009) as well as the 2004 Indian Ocean Tsunami, with local and international trauma and humanitarian interventions shaping recovery and the country’s mental health and psychosocial care infrastructure. More recently, however, psychology and mental health have been increasingly decoupled from the discourse of trauma, entering into everyday life and popular culture through the …

Settling Into Inequality: Resettled Afghans In The Washington Dc Metro Area, Harry Frey

Dissertations, Theses, and Capstone Projects

Since the Taliban returned to power in Afghanistan in August of 2021, nearly 90,000 Afghans who had fled their country have been resettled in the United States, constituting one of the largest groups of refugee arrivals in the U.S. in recent history. Working from a database I created from the administrative records of a non-profit refugee aid group, I use data and spatial analysis to examine the demographics of Afghans resettled in the DC metro area, the characteristics of the census tracts and counties in which they have been resettled, and their access to public transportation. I find that the …

Losses And Gains Of Teletherapy: The Impact Of The Pandemic On Psychoanalytic Psychotherapy, Dan-Bi Lee

Dissertations, Theses, and Capstone Projects

This qualitative phenomenological research investigates various therapeutic aspects of the transition from in-person interaction to teletherapy that began in March 2020. A semi-structured interview was conducted with each of the seventeen participants practicing in the New York City metropolitan area between the Fall of 2022 and the Spring of 2023. The questions aimed to explore changes in the psychoanalytic concepts of therapy as experienced by the therapists, including transference, enactment, fantasies, the commute, transitional space, zoom fatigue, and more. Results and discussion offer interesting insights on zoom fatigue, an ever-broadening scope of the therapeutic environment and the comparable changes in …

Rewiring The Spokes: The Future Of U.S. Bilateralism In Asia, Gian Marc Lombardo

Dissertations, Theses, and Capstone Projects

Since the end of WWII, multilateralism has consistently grown as the go-to alliance structure for the United States. Despite this, the U.S. opted to create a series of bilateral alliances after WWII in Asia, dubbed the Hub-and-Spokes system. This alliance system has not only sustained itself, but also continues to fortify itself in the face of a rising threat in Asia. China has increased its assertiveness and has shifted the balance of threat in the region, while also being the primary economic and development option for regional states. This major change in the structure of Asian power has surfaced the …

Abuse Victimization And Impulsivity In Incarcerated Males: Examining The Roles Of Affective Instability And Trauma Symptoms, Jacqueline K. Douglas

Dissertations, Theses, and Capstone Projects

Incarcerated individuals with a history of physical and/or sexual abuse have been found to exhibit increased levels of impulsivity compared to those with no abuse history (Carli et al., 2014; Davis et al., 2017; Sergentanis et al., 2014). Given that impulsivity is a risk factor for criminal delinquency (Carroll et al., 2006; Kamaluddin et al., 2015; Zimmerman, 2010), it is important to gain a thorough understanding of psychological factors that may contribute to higher levels of impulsivity in incarcerated populations. The present study examined the mechanisms underlying the relationship of physical and/or sexual abuse history to impulsivity in a sample …

Health Care Providers' Attributions Of Blame For Unintended Pregnancy And Hiv Acquisition Among Cisgender Women, Alison J. Goldberg

Dissertations, Theses, and Capstone Projects

Unintended pregnancy and HIV are both possible but preventable outcomes of vaginal sex, and both can be prevented in similar ways (condoms, daily oral medication, etc.). Despite these similarities, providers more readily prescribe contraception to cisgender women, compared to PrEP (Guttmacher Institute, 2021; Raifman et al., 2019). Providers’ differential willingness to prescribe each medication cannot be attributed merely to differences in women’s need for pregnancy prevention vs. HIV prevention, as women account for nearly 20% of new HIV infections (CDC, 2021). Through three studies, I examined whether perceivers’ support for harm reduction (i.e., prescribing PrEP/contraception) and behavior reduction (i.e., discouraging …

Illness Intrusiveness And Psychosocial Adjustment Among Older Adults With Multimorbidity, Irina Mindlis

Dissertations, Theses, and Capstone Projects

Given the high prevalence of multimorbidity (MM) among older adults and the exponential growth of the older adult U.S. population, identifying factors that can lessen depressive symptoms and improve quality of life (QOL) in this population is timely and important. While it is well established that MM is associated with greater depressive symptoms and poorer QOL (Li et al., 2016; Makovski et al., 2019; Marengoni et al., 2011; Read et al., 2017), the mechanisms underlying these relationships remain understudied. The illness intrusiveness model (Devins et al., 1984) proposes that stressors posed by diseases (disease-related factors) and their treatments (treatment-related factors) …

Epistemic Virtue And Receptivity To Science In Policing, Braden L. Campbell

Dissertations, Theses, and Capstone Projects

This dissertation investigates the underexplored relationship between character epistemology and its potential to explain behavior, decision-making, and culture within the criminal justice system, particularly the police. Building on the existing theoretical framework of evidence-based policing (EBP) and the recognized gap in understanding police receptivity to science, this study hypothesized that intellectual character at personal and collective levels positively correlates with science receptivity.

Epistemic character was defined through the aggregation of four traits: open-mindedness, defensiveness, insouciance, and groupthink. Science receptivity was measured by openness to change, desire to learn, reliance on intuition, and mistrust of science. Data were collected through surveys …

Regulating The Care Boom: Labor Standards Enforcement And Paid In-Home Care Work, Isaac Jabola-Carolus

Dissertations, Theses, and Capstone Projects

In the United States, population aging has driven explosive growth in care-sector occupations, especially among low-wage home care aides who provide long-term assistance to older adults. These aides, predominantly women and disproportionately people of color, now represent one of the country’s largest and fastest-growing occupational groups. In recent decades, economic inequality and meager social policies have also spurred demand for nannies, housecleaners, and other domestic workers—occupations heavily reliant on immigrant women, many undocumented. While scholarly and public discourse has addressed labor shortages and job quality in such occupations, a related problem is the widespread violation of labor standards, including minimum …
