Essays On Market Inefficiencies Arising From Information Asymmetry And Market Power, Ming Ge Nov 2023

Essays On Market Inefficiencies Arising From Information Asymmetry And Market Power, Ming Ge

Doctoral Dissertations

This dissertation comprises three chapters that empirically investigate various kinds of market inefficiencies arising from seller misbehaviors. The first two chapters focus on physicians' overtreatment in healthcare markets. A standard reputation system falls short of effectively curbing overtreatment due to the credence-good nature of such a market: patients cannot tell whether a high-cost treatment recommendation (versus a less costly and complex treatment) is necessary even after the service is completed. In the first chapter, I propose a novel solution to reinstate the function of reputation by combining a reputation mechanism with patient search for second opinions. I conduct a laboratory …


When Looking Up Leads To Feeling Down: Situational Moderators Of The Effects Of Social Comparisons On Social Media, Madison L. Eamiello Aug 2023

When Looking Up Leads To Feeling Down: Situational Moderators Of The Effects Of Social Comparisons On Social Media, Madison L. Eamiello

Masters Theses

Social media use is ubiquitous, especially among young adults. Negative consequences of social media use has been associated with engaging in upward social comparisons with others on social media. The current paper presents a series of two studies that seek to understand the nuances of social comparisons as they occur while browsing social media. In Study 1 (N = 161) we tested whether upward social comparisons would be less harmful when the comparer focuses on the similarities, rather than differences, with the comparison target. We observed a marginal interaction indicating that when thinking about similarities with the target, upward …


Prioritizing Climate Equity: A Qualitative Analysis Of The Massachusetts Mvp Program, Noah H. Gordon Aug 2023

Prioritizing Climate Equity: A Qualitative Analysis Of The Massachusetts Mvp Program, Noah H. Gordon

Masters Theses

The Massachusetts Municipal Vulnerability Preparedness Program (MVP Program) has funded Community Resilience Building workshops in hundreds of communities over the past 6 years. The Planning Reports produced by these workshops offer valuable insight into the climate adaptation and climate justice priorities of Massachusetts municipalities. Climate justice literature holds that the impacts of climate change will be disproportionately felt by marginalized communities, and those addressing climate change should address the risks faced by those communities, referred to as Environmental Justice (EJ) Communities in Massachusetts. Using an inductive qualitative coding approach, this study analyzes 30 Planning Reports from towns with High, Medium …


Moving Beyond The Gender Binary: A Critical Analysis And Review Of Contemporary Scholarship On Nonbinary Gender Identities, Rie Harding Aug 2023

Moving Beyond The Gender Binary: A Critical Analysis And Review Of Contemporary Scholarship On Nonbinary Gender Identities, Rie Harding

Masters Theses

For decades gender scholars have recognized the importance of gender to subjectivity, lived experiences, and life chances. Nonbinary gender identities are becoming more recognized by social, legal, and government institutions. However, currently there is a lack of research and scholarship that focuses on nonbinary gender identities. I demonstrate that the sociology of gender must move beyond the constraints of the hegemonic gender binary system in order to have a full and holistic conceptualization of gender. This paper reviews and critically analyzes contemporary interdisciplinary scholarship on nonbinary gender identities, then sets out a research agenda for moving forward. Within this scholarship …


Reconfiguring Digital Citizenship: Civic Hacking, Data Activism, And Democracy Platforms In South Korea, Danbi Yoo Aug 2023

Reconfiguring Digital Citizenship: Civic Hacking, Data Activism, And Democracy Platforms In South Korea, Danbi Yoo

Doctoral Dissertations

This dissertation focuses on ‘civic tech’, the global phenomenon of tech-based voluntary action of citizens emerging with the rise of the culture of openness and sharing and initiatives of open government data. What does the ‘civic’ of civic tech mean? And what makes civic tech democratic and democratizing? These questions have been rarely asked or conveniently understood with Western-based theories and cases of tech-oriented civic actions. Combining critical studies of technology and civic engagement with the emerging scholarship of digital citizenship, I use the concept of digital citizenship as a heuristic tool to examine how digital and data technologies intervene …


"The Land That Feminism Forgot": Birthzillas, Madwives, And The Politics Of Chilbirth, Amber Vayo Aug 2023

"The Land That Feminism Forgot": Birthzillas, Madwives, And The Politics Of Chilbirth, Amber Vayo

Doctoral Dissertations

“The Land that Feminism Forgot” is an in-depth exploration of the politics of childbirth that draws together qualitative and quantitative evidence to theorize the connections between treatment in childbirth and maternal mortality. Situating the qualitative research in the larger national context, the second chapter offers a State Reproductive Autonomy Index that provides an overview of the reproductive policy landscape at the national level. The dissertation then explores the role of institutionalized childbirth, medical mistrust, and obstetric violence in the U.S.’s longstanding maternal mortality crisis and offers policy suggestions in key public health areas. Through 120 qualitative interviews with people who …


The Evaluation Of "The Wrong Answer Project" As Validity Evidence For The Social Consequences Of Testing, Darius D. Taylor Aug 2023

The Evaluation Of "The Wrong Answer Project" As Validity Evidence For The Social Consequences Of Testing, Darius D. Taylor

Doctoral Dissertations

The use of educational tests for making high stakes decisions has had societal consequences for decades. Parents, teachers, and administrators have been willing to pay off, lie, cheat, and steal so that their children, students, and they themselves would not fall prey to the negative consequences of subpar performance on educational assessments. Respected psychometric scholars have supported Samuel Messick’s claim over the years, but their advocacy has caught minimal traction. I founded an initiative in 2019 – The Wrong Answer Project – that shows promise as a vehicle for collecting validity evidence based on the social consequences of testing and …


Examining Shifts In Racial Attitudes In The Aftermath Of George Floyd’S Death And The 2020 Blm Protests, Se Min Suh Aug 2023

Examining Shifts In Racial Attitudes In The Aftermath Of George Floyd’S Death And The 2020 Blm Protests, Se Min Suh

Doctoral Dissertations

The killing of George Floyd in the summer of 2020 instigated one of the largest social movements in the United States history. Despite the wealth of research that has evaluated the efficacy of social movements using different social outcomes (Andrews, 1997; Biggs & Andrews, 2015; Branton et al., 2015; Enos et al., 2019; Gillion, 2012; Schwartz, 2016), less attention has been given to how social movements that concern racial issues impact racial attitudes (Riley & Peterson, 2020). Thus, the current research aimed to examine how Americans’ racial attitudes shifted in the period immediately following the onset of BLM protests. We …


For The Love Of Teaching: Pre-Service Teachers’ Experience Of Moral Education, Anne Marie Foley Ruiz Aug 2023

For The Love Of Teaching: Pre-Service Teachers’ Experience Of Moral Education, Anne Marie Foley Ruiz

Doctoral Dissertations

Moral aspects of teaching arise each and every day, yet we lack information about how prepared teachers feel about this critical aspect of teaching. This multi-case study explores perceptions of five pre-service teachers in an elementary teacher education program in Western Massachusetts. A series of interviews explore their histories prior to the program and their experiences in the program as related to the pre-service teachers’ orientations to the moral work of teaching. Research questions address the awareness and self-efficacy of student teachers in implementing the moral aspects of teaching. Using Thematic Analysis (Braun & Clark, 2006), this study explores beliefs …


Increasing Teacher-Student Relationships And Classroom Engagement: The Effects Of Modifying Existing Tier Two Intervention On Adolescent Students And Their Teachers, Julia Doherty Aug 2023

Increasing Teacher-Student Relationships And Classroom Engagement: The Effects Of Modifying Existing Tier Two Intervention On Adolescent Students And Their Teachers, Julia Doherty

Doctoral Dissertations

The purpose of this study is to examine the effect of a Tier II behavior intervention, Check-in/Check-out (CiCo), on student engagement, and if a modification to the intervention that includes teacher use of microaffirmations improves the teacher-student relationship (T-SR) and thus, increases student engagement in class. It utilized multiple baseline design, and the study sample consisted of three fifth grade students from an urban school district in Southeastern Virginia. All three students were paired with one of their teachers to serve as the mentor for the intervention. Student engagement was measured directly using the Behavioral Observation System for Students (BOSS; …


Assessing Potential Cognitive Precursors To Math Anxiety: Non-Symbolic Operations And Symbolic Ordinality In Adults, Eli Zaleznik Apr 2023

Assessing Potential Cognitive Precursors To Math Anxiety: Non-Symbolic Operations And Symbolic Ordinality In Adults, Eli Zaleznik

Doctoral Dissertations

Math anxiety, or a sense of dread related to performing mathematics, affects a wide population of students and adults, but we do not fully understand how math anxiety comes into being. One possibility is the Reduced Capacities Theory, which suggests that natural variations in numeric/spatial capacities are a causal factor in math anxiety. To understand how these numeric capacities relate to math anxiety in adults, this work focuses on three areas that remain underexplored. Chapter 2 focuses on performing operations on nonsymbolic quantities, which has not yet been tested in relation to math anxiety. We tested the hypothesis that performing …


The Violence Of Nostalgia: Conspiracy Theorism, White Nationalism, And Restoring American Exceptionalism, Candice K. Travis Apr 2023

The Violence Of Nostalgia: Conspiracy Theorism, White Nationalism, And Restoring American Exceptionalism, Candice K. Travis

Doctoral Dissertations

This dissertation serves three interconnected ends: (1) highlight the connections between nationalism, nostalgia, mythology, and conspiracy, (2) research and articulate the deeper story behind the resurgence of conspiracy fueled white nationalism, and (3) analyze increasing popular support for racialized hatred across the United States as coalesced through the nostalgic desire to restore “our lost great America.” I adapt John Dewey’s pragmatism to interpret how publics take political action in response to evolving technologies and cultural shifts, and accordingly develop a typology of groups on the right wing of American politics. The Proud Boys are chauvinist white nationalists, Patriot Prayer are …


On The Importance Of Perceived Interpersonal Safety: Antecedents And Consequences Of Living A Subjectively Safe Life, Stylianos Syropoulos Apr 2023

On The Importance Of Perceived Interpersonal Safety: Antecedents And Consequences Of Living A Subjectively Safe Life, Stylianos Syropoulos

Doctoral Dissertations

The need to be and feel safe is a fundamental human need. Despite extensive theoretical arguments on the subject, and research on relevant concepts, empirical work on what it means to feel interpersonally safe (i.e., in the presence of others or in social environments in general) is scarce. This dissertation presents four investigations that seek to address this gap. It also seeks to highlight the consequences of feeling interpersonally safe for our mental and physical health, and to what degree healthy and high-quality close relationships influence how safe we feel. Chapter 1 is a literature review summarizing theories underlying these …


Modeling Spatial Distributions Of Tidal Marsh Blue Carbon Using Morphometric Parameters From Lidar, Bonnie Turek Apr 2023

Modeling Spatial Distributions Of Tidal Marsh Blue Carbon Using Morphometric Parameters From Lidar, Bonnie Turek

Masters Theses

Tidal marshes serve as important “blue carbon” ecosystems that accrete large amounts of carbon with limited area. While much attention has been paid to the spatial variability of sedimentation within salt marshes, less work has been done to characterize spatial variability in marsh carbon density. Driven by tidal inundation, surface topography, and sediment supply, soil properties in marshes vary spatially with several parameters, including marsh platform elevation and proximity to the marsh edge and tidal creek network. We used lidar to extract these morphometric parameters from tidal marshes to map soil organic carbon (SOC) at the meter scale. Fixed volume …


Three Essays On Macroeconomics And Development, Guilherme Klein Martins Apr 2023

Three Essays On Macroeconomics And Development, Guilherme Klein Martins

Doctoral Dissertations

This dissertation is a collection of essays that relate, in different forms, macroeconomic policies to economic development. Essay 1 provides evidence that austerity shocks have longrun negative effects on GDP. Besides addressing the important gap in the growing fiscal research regarding the short time horizon of the estimations, the paper analyzes two other important assumptions made in the literature regarding the (i) symmetry of episodes of fiscal expansion and contraction and (ii) uniformity of fiscal multipliers for different sizes of shocks. We use narrative fiscal shocks and propensity score reweighting in a local projections setup to account for the potential …


The Abolition Of Care: An Engaged Ethnography Of The Progressive Jail Assemblage, Justin Helepololei Apr 2023

The Abolition Of Care: An Engaged Ethnography Of The Progressive Jail Assemblage, Justin Helepololei

Doctoral Dissertations

This dissertation draws on ethnographic research conducted with prison abolitionists and criminal justice reform activists in Western Massachusetts - a context in which the sheriffs who operate county jails see themselves as reformers. I use the concept of a “progressive jail assemblage” to analyze the varied actors and logics that sustain incarceration locally, focusing especially on the use of care discourses and practices. I consider how progressive jailing puts prison abolitionists in the position of being against some forms of care. At the same time, abolitionists have put forth competing notions of care, ones they see as building a world …


The Economics Of Information And Communication Technologies In Our Society, Augusto Espin Apr 2023

The Economics Of Information And Communication Technologies In Our Society, Augusto Espin

Doctoral Dissertations

Information and Communication Technologies (ICTs) play a fundamental role in today's society. As ICTs they become more mature and widely adopted, societies become more dependent on their use to operationalize daily activities. However, there are multiple societal impacts of ICTs that are not yet well understood. In this dissertation, I explore three different aspects of ICTs that have been widely discussed by media and industry during recent years. I analyze these topics from an economic perspective, contributing to the debate with rigorous modeling and the ensuing discussion of its implications. First, I study the impact that the COVID-19 pandemic had …


Between Verb And Preposition: Diachronic Stages Of Coverbs In Mandarin Chinese, Glynis Jones Apr 2023

Between Verb And Preposition: Diachronic Stages Of Coverbs In Mandarin Chinese, Glynis Jones

Masters Theses

Mandarin Chinese has long been known to possess a category of words known as ‘coverbs’ in the literature, which sit in the gray area between verb and preposition. Li and Thompson (1974) describe the historical origins of Mandarin coverbs to be full transitive verbs, despite their modern state being decidedly less verbal. They also note that coverbs are a non-homogenous class. This thesis works to establish categories of coverbs in Mandarin Chinese and their distance from true verbhood in order to understand the diachronic shift that coverbs are currently undergoing before our very eyes. I will draw on the work …


Borderline Personality Disorder And Posttraumatic Stress Disorder: Unique Patterns Of Emotion Reactivity And Regulation, Clara Defontes Oct 2022

Borderline Personality Disorder And Posttraumatic Stress Disorder: Unique Patterns Of Emotion Reactivity And Regulation, Clara Defontes

Masters Theses

Both borderline personality disorder (BPD) and posttraumatic stress disorder (PTSD) are associated with emotion dysfunction and often co-occur. Emotional reactivity is also evident in some studies in BPD and PTSD. Despite the frequent co-occurrence of these diagnoses, only a few studies have examined the independent and joint effects of BPD and PTSD on emotional functioning. Some data suggest that co-occurring PTSD may drive discordance between domains of emotional reactivity in BPD, dampening physiological reactivity but increasing subjective reactivity. Low reliance on acceptance-based emotion regulation may also account for this divergence. The current study examined the independent and interactive effects of …


Lgbtq+ Divergent Paths In Utah: Identity And Space-Making Practices In Queer And Religious Spaces, Taliah C. Mortensen Oct 2022

Lgbtq+ Divergent Paths In Utah: Identity And Space-Making Practices In Queer And Religious Spaces, Taliah C. Mortensen

Masters Theses

This research explores the unique and divergent experiences of LGBTQ+ young adults as they engage in identity and space-making practices at the intersection of gender/sexuality and religion. Utilizing queer theorists’ conceptualization of identity as a form of embodied and spatial labor, I critique the approach of existing scholarship that constructs LGBTQ+ and religious identities as incompatible or at least in need of reconciliation. Based on thirteen semi-structured interviews with LGBTQ+ young adults in Utah, my research makes visible how vulnerability and risk impact the strategies that LGBTQ+ young adults employ to navigate their identities and make space. It shows that …


Youth-Perceived Variability In Harsh Parenting From 8-14 Years As A Predictor Of Internalizing And Externalizing Symptoms At 15 Years, Ann E. Folker Oct 2022

Youth-Perceived Variability In Harsh Parenting From 8-14 Years As A Predictor Of Internalizing And Externalizing Symptoms At 15 Years, Ann E. Folker

Masters Theses

Harsh parenting behaviors have been shown to predict internalizing and externalizing symptoms in children. These symptoms of psychopathology can persist into adolescence, which can negatively impact social, academic, and emotional functioning. Most studies, however, focus on between-person differences in average harsh parenting, rather than within-person changes in harsh parenting over time. This variability in harsh parenting has a potentially unique impact on the development of adolescent psychopathology. The present study aims to understand if child/adolescent-perceived variability in harsh parenting over time (intraindividual variability; IIV) predicts higher levels of internalizing and externalizing symptoms in mid-adolescence, while controlling for average levels of …


Changing Criteria: What Decision Processes Reveal About Confidence In Memory, Johanny N. Castillo Oct 2022

Changing Criteria: What Decision Processes Reveal About Confidence In Memory, Johanny N. Castillo

Masters Theses

Source memory is our ability to relate central information (the “item”) to the context (the “source”) in which it was learned or experienced. People are often highly confident in their source judgements even when this information is incorrectly recalled. Past work has aimed to explain why source errors made with high confidence occur with a framework called the Converging Criteria (CC) account. The CC account posits that item memory can interact with source memory by altering decision criteria as item confidence increases, increasing the probability of a high confidence source judgement. This prediction differs from alternate models, like the Fixed …


A New Way To Get Groceries? Ride-Hail Services And Navigating Outside Of Food Deserts, Kathryn Reynolds Oct 2022

A New Way To Get Groceries? Ride-Hail Services And Navigating Outside Of Food Deserts, Kathryn Reynolds

Masters Theses

Segregation has many negative consequences for marginalized populations, including poor health, increased poverty, low-quality housing, and limited education and employment opportunities. Scholars have recently recognized access to food as another piece of this “advanced marginality.” This study illuminates how lagging food and transportation infrastructures exacerbates these interlocking inequalities and whether new ride-hail technologies' promise that ride-hail services like Uber and Lyft will help affected populations access food stores with lower prices and higher food quality. As a descriptive understanding of the intersection between food, transportation, and racial residential segregation in Chicago, Illinois, this study analyzes two questions: (1) how often …


Borderline Personality Disorder And Learning: The Influences Of Emotional State And Social Versus Nonsocial Feedback, Elinor E. Waite Oct 2022

Borderline Personality Disorder And Learning: The Influences Of Emotional State And Social Versus Nonsocial Feedback, Elinor E. Waite

Masters Theses

Borderline personality disorder (BPD) has been linked to impulsive behaviors, interpersonal difficulties, and emotional reactivity. Although these impairments imply underlying deficits in decision-making, theory suggests that such deficits may be context dependent. Both emotional state and social context may influence learning in BPD. Reinforcement learning models offer an avenue to parse types of impairments in learning. The current study used reinforcement learning models to examine whether the type of feedback (social vs. nonsocial) moderates the association between BPD and learning under conditions of distress. Adults with BPD (N = 37), subthreshold BPD (N = 29), and without BPD …


The Role Of Autobiographical Memory Recall In Reappraisal Efficacy And Effort Across Age, Irina Orlovsky Oct 2022

The Role Of Autobiographical Memory Recall In Reappraisal Efficacy And Effort Across Age, Irina Orlovsky

Masters Theses

Socioemotional theories posit that the experience of overcoming unique life challenges over a lifetime enhances self-efficacy and emotional resilience among older adults. Older adults demonstrate greater emotional well-being and motivation to regulate emotions than younger adults, but specific regulatory mechanisms supporting late-life emotional resilience remain unclear. Cognitive reappraisal is an effective but cognitively demanding emotion regulation strategy and shows mixed efficacy in later-life. While a growing repertoire of autobiographical memories may be a resource with age, the role of autobiographical recall in momentary reappraisal has never been tested empirically. In this online study, older and younger adults were trained to …


Three Essays On The Political Economy Of Cultural Production And Creative Labor, Luke Pretz Oct 2022

Three Essays On The Political Economy Of Cultural Production And Creative Labor, Luke Pretz

Doctoral Dissertations

This dissertation investigates the relationships between capital, cultural production, and creative labor. Essay one theorizes the basis for the intensification of pop music stardom following the introduction of on-demand streaming technology. Prior to the emergence of on-demand streaming, record labels and broadcasters had a mutualistic relationship, wherein the near cost-free music provided by record labels formed the basis for radio broadcasts, which in turn formed the basis for the consumption of that music. Following the emergence of on-demand streaming the mutualistic relationship was ruptured. Broadcasters, in the form of streaming platforms, transitioned to the cost-efficient cultivation of masses of highly …


Three Essays On The Political Economy Of The Cfa Franc, Francis Perez Oct 2022

Three Essays On The Political Economy Of The Cfa Franc, Francis Perez

Doctoral Dissertations

This dissertation is organized into three essays. The second essay provides a historical overview of the CFA franc and explores why the CFA franc has survived for so long. It argues that a historical and dialectical materialist analysis of the CFA’s history can best explain both its extraordinary longevity and the periodic major reforms to its functioning. The third essay assesses whether the Central Bank of West African States (BCEAO) has an independent monetary policy by examining the relationships between BCEAO’s foreign reserves and base money, and between BCEAO and the European Central Banks’s policy rates. The fourth essay evaluates …


Phonotactic Learning With Distributional Representations, Max A. Nelson Oct 2022

Phonotactic Learning With Distributional Representations, Max A. Nelson

Doctoral Dissertations

This dissertation explores the possibility that the phonological grammar manipulates phone representations based on learned distributional class memberships rather than those based on substantive linguistic features. In doing so, this work makes three primary contributions. First, I propose three novel algorithms for learning a phonological class system from the distributional statistics of a language, all of which are based on partitioning graph representations of phone distributions. Second, I propose a new method for fitting Maximum Entropy phonotactic grammars, MaxEntGrams, which offers theoretical complexity improvements over the widely-adopted approach taken by Hayes and Wilson [2008]. Third, I present a series of …


The Quotidian Quantifier: Fitness Tracking And The Mundanity Of Surveillance, Marianne Neal-Joyce Oct 2022

The Quotidian Quantifier: Fitness Tracking And The Mundanity Of Surveillance, Marianne Neal-Joyce

Doctoral Dissertations

This dissertation uses the rise of wearable fitness tracking as a lens through which to examine the predominance of quantification in everyday life. With over a third of U.S. adults owning a tracker, the increased use of body-surveilling technologies provides an opportunity to investigate some central sociological questions. In this project, I ask why individuals track their health behaviors with technology and how we may understand this behavior in the context of medical and corporate interests. I further ask how people think about the privacy implications of their use and what concerns they have about data collection and sharing. I …


Productive Women: Gender, Sex, And Labor In The Digital Cultural Economy, Kavita Nayar-Jablonka Oct 2022

Productive Women: Gender, Sex, And Labor In The Digital Cultural Economy, Kavita Nayar-Jablonka

Doctoral Dissertations

Explicit sex and sexuality have come to figure more prominently in mainstream media and popular culture in recent years, sparking public concern and scholarly debate on how the “sexualization” of culture particularly affects women. Against this backdrop and amidst digitally reconfigured circuits of media production and consumption, ordinary women participate in, and potentially profit from, the commodification of sexual interactions and relationships. This study compares women’s practices in cultures of cam modeling and sugar dating in order to better understand their meanings and contexts. Whether performed in tandem with romantic dating scripts and roles, as is common in sugar dating, …
