Dangerous Dice: Playing With Artificial Intelligence And Populism During Brazil's 2018 Election, Glen Salazar

Master's Theses

With the advent of artificial intelligence and the resurgence of populism, in particular right-wing populism, we see nationalist parties that were once on the fringes of mainstream politics gain power around the world. Putting under the limelight the recent electoral victories of world leaders riding this new wave of populism, we recognize a troubling new reality: the confluence of artificial intelligence and populism allows for election interference through the spread of disinformation, propaganda, and emotionally charged populist rhetoric on social media. This tectonic shift in election tactics used by extreme nationalists presents an existential threat to democracy, with the potential …

Transdiagnostic Multimodal Neural Correlates Of Psychosis Dimensions, Dov Bernard Lerman-Sinkoff

McKelvey School of Engineering Graduate Student Theses & Dissertations

Psychosis refers to a debilitating set of symptoms that impacts individuals, their communities, and society at large. Current psychiatric nosology treats psychosis as a categorical construct. However, recent evidence suggests that a dimensional approach that cuts across extant nosological boundaries may more accurately represent the underlying phenomena contributing to dysfunction in psychosis. One putative domain of transdiagnostic variation is cognitive control, a construct that refers to the set of functions that enable and support goal-directed behavior and regulation of one’s thoughts and actions. Previous analyses in both healthy individuals and individuals with psychosis have led to a number of findings …

Essays On Money And Banking, Macroeconomics, And Political Economy, David Lindequist

Arts & Sciences Graduate Student Theses and Dissertations

This thesis consists of three self-contained articles. In the first article "The Common Currency Channel of Risk Sharing", I propose a new channel of international risk sharing: the common currency channel. I show theoretically that the central bank of a currency union can use the common currency to insure member countries against consumption risk from idiosyncratic productivity shocks. A trade-off between risk-sharing and moral hazard emerges: a central bank which enables risk sharing induces countries to free ride on each other’s production efforts. I study this trade-off and derive rules for a central bank striking the optimal balance between insurance …

Essays On Asset Pricing: A Model Comparison Perspective, Lingxiao Zhao

Arts & Sciences Graduate Student Theses and Dissertations

In my dissertation, I focus on theoretical and empirical asset pricing from a Bayesian model comparison perspective. In the first Chapter, revisiting the framework of Barillas and Shanken (2018), BS henceforth, we show that the Bayesian marginal likelihood-based model comparison method in that paper is unsound: the priors on the nuisance parameters across models must satisfy a change of variable property for densities that is violated by the Jeffreys priors used in the BS method. Extensive simulation exercises confirm that the BS method performs unsatisfactorily. We derive a new class of improper priors on the nuisance parameters, starting from a …

Essays On Consumer Online Search And Digital Content Consumption, Shuo Zhang

Arts & Sciences Graduate Student Theses and Dissertations

In my dissertation, I apply empirical quantitative methods to marketing research and investigate consumer online search and purchase patterns, as well as digital consumption behaviors and the potential implication for marketing managers. This dissertation consists of two chapters. Chapter 1 studies the consumer shopping channel choice when they search and shop for products online. Mobile phones have emerged as a major channel for online shopping as an alternative to PCs. Despite more consumers using mobile phones, the conversion rate on the mobile channel is lower than that on the PC channel. In this study, we propose a structural consumer search-and-purchase …

Essays On Institutions Governing Marriage And Outcomes Over The Life Cycle, Sounak Thakur

Arts & Sciences Graduate Student Theses and Dissertations

In this thesis, I study how institutions that govern marriage can affect marital choices and economic decisionmaking within marriage. The institutions that I study encompass both formal institutions, like laws that govern family formation, or more informal ones, like customs mandating the amount and direction of transfers at marriage or the level of commitment within marriage. This thesis consists of three chapters, and each chapter tackles a specific research problem under the broad research agenda. In the first chapter of my thesis, I study how changes in divorce and property division laws affect the rates of marriage formation, marital sorting …

Maintaining Natural Recovery From Prescription Opioid Use Disorder, Christina Drymon

Arts & Sciences Graduate Student Theses and Dissertations

Prescription opioid use disorder (POUD) has been steadily rising in the United States since 1999 and is often accompanied by increases in heroin and synthetic opioid use, overdose deaths, and other adverse public health outcomes. Women in particular are at greater risk of developing POUD and associated outcomes. Even though high rates of mortality and morbidity are common among those with POUD, recovery is possible with nearly half of all individuals with POUD recovering naturally (i. e. , without formal or informal treatment). The natural recovery process from POUD has received little empirical attention. Using a grounded theory approach, semi-structured …

Information And The Risk-Neutral Probability, Essays In Financial Econometrics, Michael G. Zdinak

Arts & Sciences Graduate Student Theses and Dissertations

This article introduces a new high-frequency analysis of six years of data for options written on the S&P 500 and traded on the Chicago Board of Exchange. I quantify in real time the information contained in the probability measure implied by option prices, using concepts developed in information theory. Here information is analogous to a reduction in uncertainty surrounding the future price of the underlying security. A simple nonparametric estimator allows us to measure the amount of information gained as an option approaches maturity. I then test for jumps in the expectation of said future price. I find the intraday …

Horse Power: The Merry-Go-Round Of Kentucky's Transforming Thoroughbred Racing Industry, S. Carolyn Barnes

Arts & Sciences Graduate Student Theses and Dissertations

This dissertation explores Thoroughbred training and racing in central Kentucky’s “horse country,” the most culturally and economically invested horse racing region in the United States. In recent decades, public interest in horse racing has waned and this sporting industry has intensified the use of biomedical interventions, including pharmaceuticals. This is fueling rising ethical concerns about the welfare and treatment of racehorses and calls for reform, including federal oversight and regulation of the sport. Given these changes and pressures, I have sought to understand what it is like to live and work in this agrarian world. Supported by the Wenner- Gren …

Beluu El Diak Le Belumam: Reclaiming And Decolonizing Palauan-American Cultural Heritage, Connie Ngirchemat

Master's Theses

Prior to colonization, Palau practiced their own indigenous ways of knowledge and epistemologies in relation to their spirits, land, and community. Through Palau’s colonial and imperial relationships under Spain, Germany, Japan, and evidently the United States, these impacts throughout Palau’s history have affected the community’s traditional ways of knowing. From colonial influences, to the evident emigration of the Palauan diaspora, this created a new generation of Palauan-Americans, who were raised unfamiliar with their cultural heritage and language. This lack of cultural awareness for the Palauan-American diaspora raises concerns of loss of culture, sense of self and identity, and its impact …

Oil Price Changes And Unemployment Rate In The U.S. And Chile, Agamani Maity

Master's Theses

Abstract

There is a recurring question in theoretical, empirical and policy work is what the effects of higher oil prices are on the country’s macroeconomic aggregates. Empirical evidence in support of the view that fluctuation in the economy due to the interaction of macroeconomic variables is caused by oil price was based on inappropriate econometric models. These studies do not capture the composition of the price of oil that is affected by the exogenous oil shocks and has an indirect or direct impact on the macroeconomic aggregates. In this study, we decompose the change in oil prices into three structural …

Who Benefits From Park And Recreation Improvements In San Francisco? A Case Study Of Recreation Center Renovations In San Francisco, Safia Belayadi

Master's Theses

The purpose of this study is to examine the efficacy of city policies undertaking public goods investments to benefit disadvantaged communities in San Francisco. Namely, is the process of improving the quality of public goods serving targeted populations, or does it lead to unintended consequences such as gentrification? I take advantage of the timing of city recreation center renovations and the synthetic control method to capture any difference in the proportion of users that is poor before and after the renovation date. I use San Francisco Recreation and Park Department registrant data containing user zip codes and census demographic data …

The Effect Of Sex Of Firstborn Children On Attitudes Towards Intimate Partner Violence, Shuvam Rizal

Master's Theses

What are the different ways in which one’s life is influenced by the sex of their children? Is there an effect on how they view Intimate Partner Violence? If so, is there a difference in how the male parent is affected by the sex of his child than the female parent? Bodies of conflicting Social Sciences literature suggest having a daughter makes one both more and less likely to engage in Intimate Partner Violence. In this paper, I approach this question through the use of a Linear Probability Fixed-Effects model on Demographic Health Surveys (DHS) datasets, using data from the …

Rompiendo Alambres: Immigrant Youth Navigating School And Life In St. Louis, Julia Campus Macias

Arts & Sciences Graduate Student Theses and Dissertations

This project focuses on educational and life trajectories of Central American youth in St. Louis, Missouri, who have immigrated unaccompanied from Guatemala, El Salvador, Honduras, and Nicaragua. By tracking and telling their stories, I hope to amplify these young immigrants’ voices, and complicate others’ perceptions of their place and worth in this country. Current immigration policies and enforcement practices have made the entry process more punitive, restrictive and deadly. The immigrant experience, especially for young people, confronts many state institutions, chief among them the educational system. Institutions like schools become entry points for immigrants but can also be spaces for …

Child Sexual Abuse Prevention Group, Brooklyn Kennedy Thompson

Dissertations, Theses, and Projects

The purpose of this literature review is to evaluate the use of child sexual abuse (CSA) prevention programs with elementary school children. Being that child sexual abuse is a multifaceted problem, there are many aspects to examine among the larger issue at hand. Through the use of thorough research, these aspects were identified. First, recognizing risk factors of child sexual abuse aid in identifying vulnerable children. Second, parental involvement in prevention programs is essential. Parents must acquire the knowledge and tools they need to create safe environments for their children, as well as be able to openly and affectively discuss …

School Violence Threat Assessment: Professional Development Training For K-12 Educators, Christopher J. Potter

Dissertations, Theses, and Projects

While threats of violence are relatively common in U.S. K-12 schools, the likelihood of a threat being carried out is very low. School leaders must take all threats of school violence seriously but must also have evidence-informed means to discern less-serious, transient threats from more serious, substantive ones. School violence threat assessment training is a vital professional development tool, to ensure safer schools while avoiding unnecessary labeling of students or overly harsh consequences through disciplinary over-reaction. This manual supplements an abbreviated professional development training presentation on school violence threat assessment based on research and models developed by Dr. Dewey Cornell, …

Dismantling Of Obesity-Related Policies, Alexandra Borosova Morshed

Arts & Sciences Graduate Student Theses and Dissertations

This dissertation fills an important research gap in the study of obesity policymaking by characterizing to what extent the phenomenon of dismantling is happening at the state level for obesity-related policies targeting the context of consumption, identifying determinants, and characterizing actors and processes involved. The five-year rate of dismantling of these policies is close to one-third for any attempts and one-tenth for enacted dismantling. Food and beverage tax policies face a particularly high rate of dismantling. Case studies and news coverage of state- level dismantling identified actors, motivations, and strategies used in the process of dismantling. Review of health-related empirical …

How To Represent: The Role Of Perceptions, Cognitive Biases, And Information On Elite Responsiveness, Miguel Maria Pereira

Arts & Sciences Graduate Student Theses and Dissertations

This dissertation studies the links between voters and their representatives in Western Europe. Each chapter explores specific mechanisms through which politicians build their image of the electorate and translate this image into policy. In the first main chapter, I study why politicians misperceive voter preferences and how to overcome distorted beliefs about the electorate. I argue that elite misperceptions result from inequalities in exposure to voters and egocentric biases of politicians. I find support for these arguments in a panel of Swedish MPs covering two decades. In turn, a novel experiment leveraging real political events in Switzerland shows how encouraging …

All The Presidents' Organized Interests, David Ryan Miller

Arts & Sciences Graduate Student Theses and Dissertations

My dissertation examines presidents' interactions with organized interests. Despite ample observable evidence that presidents and organized interests frequently interact, many scholarly studies of the presidency argue that these interactions are non-existent, infrequent, or inconsequential. I argue that presidents engage with organized interests as part of their coalition-building efforts, as they seek to secure organized interests' electoral and policy resources to advance their own goals. I further argue that both presidents and organized interests benefit from this engagement. I assess my arguments by evaluating three interrelated questions: with which organized interests do presidents engage?; how do presidents encourage the interests with …

Testing Assumptions On The Relationship Between Humans And Their Environment: Case Studies From Cahokia Mounds, Illinois, Caitlin Gail Rankin

Arts & Sciences Graduate Student Theses and Dissertations

Many archaeologists argue that studying past human response to climate change can be helpful in informing future strategies to adapt to modern effects of climate change; however, archaeological research is rarely utilized in climate change policy. Much of archaeological research involves forming hypotheses to explain observations of past phenomena. However, the advancement of knowledge requires a back and forth between hypothesis forming and hypothesis testing. I argue that a lack of engagement in hypothesis testing has stalled the advancement in archaeological knowledge on the relationship between humans and their environment. Ultimately, it is this stall in the advancement of knowledge …

Building Communities: Interpreting Oneota And Mississipppian Interaction Through Paleoethnobotanical Analysis At The Morton Village Site (11f2), West-Central Illinois, Kelsey Olivia Nordine

Arts & Sciences Graduate Student Theses and Dissertations

Archaeological investigations of social interaction at the community level provide insight into the daily lives of past people and the social structures that guide these community-level interactions. This dissertation uses paleoethnobotanical analysis to examine the nature of social identity negotiation and community at the site-level scale, using data from excavations at the Morton Village site (11F2). Morton Village is a Bold Counselor Oneota and Mississippian settlement in the Central Illinois River Valley (CIRV), occupied contemporaneously by both groups in the 14th century and identified as a multiethnic or multicultural village through the presence of two distinct types of ceramic remains. …

The Social Dynamics Of Antibiotic Use In A Large American Medical Complex, Katharina Rynkiewich

Arts & Sciences Graduate Student Theses and Dissertations

Based on 18 months of anthropological fieldwork, 35 in-depth interviews, and over 360 hours of participant observation with two specialty physician groups, my dissertation is an analysis of the social dynamics involved in antibiotic decision making, prescription, and use at a large North American medical complex in a Midwestern city. Due to the global problem of antimicrobial resistance, hospitals have been particularly interested in reducing antibiotic overuse and misuse. Though the use of antibiotics has long had an impact at the population level, physicians often advocate for additional antibiotic coverage in the individual patient. I examine a policy aimed at …

Essays On Growth, Development, And Human Capital, Juan Ignacio Vizcaino

Arts & Sciences Graduate Student Theses and Dissertations

Skills, Technologies and Development. I study how the productivity of skilled and unskilled labor varies with development. Using harmonized, occupational labor market outcomes for a broad set of countries across the development spectrum, I document that employment in high-skill occupations, or jobs that are relatively more intensive in non-routine cognitive tasks, grows with development. In addition, the income of workers in high-skill occupations falls relative to earnings in low-skill occupations as countries grow richer. To understand the forces driving these findings, I develop a stylized model of the labor market across development. In the model, labor productivity is determined endogenously …

Understanding Task Interference In Prospective Memory Using On-Line Probes: Strategic Delay Or Limited-Capacity Monitoring?, Francis T. Anderson

Arts & Sciences Graduate Student Theses and Dissertations

In prospective memory (PM) research, a common finding is that people are generally slower to respond to a given ongoing task (OT) when they have to perform a PM task concurrently, as compared to performing the OT alone. Multiprocess theory claims that this slowing, termed task interference, is indicative of monitoring processes. Monitoring is thought to be cognitively demanding and heavily reliant on working memory, as people hold their intention in mind and look for features relevant to the PM task. PM decision control (PMDC) theory, instead, proposes that task interference reflects a strategic and intentional delay strategy. To address …

The Effects Of Monitoring Expression And Outgroup Familiarity On Judgments Of Other-Race Interaction Partners, Katlin Bentley

Arts & Sciences Graduate Student Theses and Dissertations

Research on emotion communication demonstrates that people are more accurate at recognizing emotion when evaluating members of one’s racial ingroup compared to assessments made for outgroups. It is unclear what leads us to make erroneous outgroup judgments. Two factors may play a central role in this process: judges’ attentiveness to and knowledge about partners’ group-specific expressive behaviors. In this project, I tested moderators of people’s ability to accurately detect emotions during an in-person interaction when paired with a same- or other-race partner. Findings indicate that when playing a cooperative game, people are surprisingly adept at accurately judging outgroup emotions, but …

Consuming Local, Thinking Global: Building A Halal Industry In A World Of Made In Italy, Lauren Virginia Crossland-Marr

Arts & Sciences Graduate Student Theses and Dissertations

Consumers today seek guidance on how to decipher where their food comes from. As a result of this demand, food certifications have materialized in stores across the globe. Walking through oneճ local grocery store, one is bombarded with certifications that range from ҭade inӠto organic to kosher. Research on forms of food certifications have emphasized the process of making these certifications legible to consumers in markets abroad, overlooking the impact of local concerns in building certifications. This study aims to determine the impact of local cultural foodways on certification schemes meant for global markets. Building on existing work in the …

Essays On Macro And Financial Economics, Linyi Cao

Arts & Sciences Graduate Student Theses and Dissertations

Nurturing Young Public Firms over Real Business Cycles. In this paper, I develop a theory of financial intermediation in a general equilibrium environment, to study the interactions between households, financial intermediation, and entrepreneurs over real business cycles. In the model, the financial intermediary, who resembles real-life private equity (PE) groups and investment bankers, works as a nurturer of young public firms. It performs screening and sorting on entrepreneurs, then allocates resources to them, borrowed from the households. However, the effort intensity in screening decreases when the financial intermediary is flooded by resources, so do the average quality of financial services …

Neural Mechanisms Of Cognitive Individual Difference: An Investigation Of The Human Connectome Project, Shelly Renee Cooper

Arts & Sciences Graduate Student Theses and Dissertations

Considering individual differences in task activation functional magnetic resonance imaging (t-fMRI) can be challenging because they may arise from variability in activity in brain regions, in the tasks themselves, or some combination thereof. Delineating sources of between-subjects variance is particularly important for cognitive control where task goals are at the forefront. Here we applied structural equation modeling (SEM) to the Human Connectome Project to examine if activity could be partitioned into separable brain and task individual difference dimensions. A series of SEMs were defined with varying numbers of latent factors, where the inputs were parcels of two cognitive control-related brain …

A Case Study Of The Experiences Of Black Female Faculty At Research-Intensive Schools Of Social Work, Lashawnda N. Fields

Arts & Sciences Graduate Student Theses and Dissertations

Representation has improved over the past 40 years among Black female faculty members in social work schools; however, low academic rank and distribution of this demographic across institutions is one way in which predominately White institutions (PWI) of higher education perpetuate racial inequalities. Higher education, in general, continues to result in negative experiences and poor outcomes for Black female faculty members such as time to tenure, low academic rank, and feelings of isolation. However, little is known about the experiences of this demographic in schools of social work, particularly those identified as research-intensive (R-1) Carnegie-designated institutions of higher education. This …

Subjectivities Of Struggle: Charting Inscriptions Of Violence And Refusal On The “Cuerpo Territorio” Of Peru’S Defensoras, Natalia Guzmán Solano

Arts & Sciences Graduate Student Theses and Dissertations

“Subjectivities of Struggle: Inscriptions of Violence and Refusal on the ‘Cuerpo Territorio’ of Peru’s Defensoras” calls into question the colonial assumptions underpinning contemporary understandings of extractivism. The sixteen months of ethnographic research I conducted with the defensoras (women ecoterritorial defenders) of Cajamarca is situated at the fraught extractive frontier where social conflict paralyzed the expansion of a large-scale mining project and generated a coalitional struggle against extractive-led economic development. This dissertation conceptualizes extractivism as a modern/colonial product of power and knowledge that has feminized the land and inhabitants from the time of the European invasion of the Americas. While recent …
