Is The South (Still) America’S Sacrifice Zone? A Regional Analysis Of Toxic Emissions, 1987–2017, Tanesha A. Thomas

Dissertations, Theses, and Capstone Projects

The southern United States has been labeled a “sacrifice zone” for the rest of the nation's toxic waste. In the early days of the environmental justice movement, researchers found that the south contained a disproportionate number of toxic sites, including garbage dumps, landfills, and waste incinerators. These initial studies used different data sources and methodologies, but arrived at the same conclusion: America was dumping in Dixie, a predominantly poor African American region of the country. Since then, researchers have mainly confirmed or called into question the existence of environmental racism within the south. However, none have investigated the south’s environmental …

Dietary Development And Nutritional Ontogeny In Gorilla Beringei : A Multi-Layered, -Omics Approach, Emma C. Cancelliere

Dissertations, Theses, and Capstone Projects

In species who consume folivorous diets, immature individuals must contend with the challenges of extracting nutrients from fibrous foods before dietary adaptations and strategies are fully developed. Additionally, immatures have distinct nutritional needs to support their stage-specific metabolic and biophysiological requirements. To meet these stage-specific needs, while constrained by underdeveloped feeding strategies and digestive capacities, immatures may adopt distinct diets better suited to their specific developmental context. However, where dietary modification is constrained by low dietary diversity or landscape homogeneity, it is unclear how immature individuals compensate through alternative strategies. In turn, little is known about the nutritional and life …

The Squeaky Wheel Gets The Oil? On The Interpersonal Effects Of Boredom Expression, Manuel F. Gonzalez

Dissertations, Theses, and Capstone Projects

I explored how people react to employees who express boredom at work. I consider boredom expression as a social signal that the current situation does not adequately stimulate the expresser. The expression may then propel others to help stimulate the expresser, depending partly on others’ initial appraisals and reactions to the expression, and on the surrounding context. In Study 1, using qualitative surveys, I uncovered various affective, cognitive, and behavioral reactions to employees who expressed boredom. In Study 2, using experimental vignettes, I manipulated the emotion expressed by a “subordinate” (boredom, enthusiasm, or no emotion) and the manager’s beliefs about …

“The Little Seed And The Wind”: Digital Intervention Tool For Geography And Empathy, Maritha Pocorni-Humphries

Dissertations, Theses, and Capstone Projects

Educational researchers agree that there is an absence of student engagement in our primary education institutions. They also acknowledge that learner engagement could enhance their overall behavior. What could be done to promote learning, involve students and sustain their motivation? Why should we admit that students tend to show more involvement and engagement during digital interactivity? This paper describes my motivation behind my designed digital geographical educational intervention tool which in a playful way introduces and teaches 4- and 5-years old children the seven continents and the seven oceans. Drawing on the underpinning concept of game-based learning theory my framework …

Lengua, Identidad Y Poder: Ideologías Lingüísticas En La Prensa Hispana De Los Estados Unidos (1980–2007), Evangelia-Lydia Manatou

Dissertations, Theses, and Capstone Projects

Esta tesis estudia las ideologías que articulan los tres periódicos hispanófonos de distribución más amplia, en los Estados Unidos, desde finales del siglo XX, al reproducir los debates vinculados a la lengua española y los valores asignados a distintas prácticas lingüísticas producidas por los hispanohablantes que residen en EE. UU. En particular, nos ha interesado por fenómenos tales como el monolingüismo, el bilingüismo y el espanglish, y por las propuestas normativas articuladas tanto por los periódicos como por instituciones españolas dedicadas a la promoción internacional de la lengua. En este trabajo hemos analizado artículos y viñetas de los tres periódicos …

Small Molecule Synthetic Carbohydrate Receptors, Marcelo F. Bravo Carranco

Dissertations, Theses, and Capstone Projects

Carbohydrate – receptor interactions are often involved in the attachment of viruses to host cells, and this docking is a necessary step in the virus life cycle that precedes infection and, ultimately, replication. Despite the conserved structures of the glycans involved in docking, they are still considered “undruggable”, meaning these glycans are beyond the scope of conventional pharmacological strategies. Recent advances in the development of synthetic carbohydrate receptors (SCRs) – small molecules that bind carbohydrates – could bring carbohydrate-receptor interactions within the purview of druggable targets. Here we discuss the role of carbohydrate-receptor interactions in viral infection, the evolution of …

Overcoming Challenges In The Assessment And Treatment Of Problem Behavior In Adults With Autism, Julia A. Iannaccone

Dissertations, Theses, and Capstone Projects

Problematic behaviors, such as self-injurious behavior or aggression, demonstrated by adults with autism spectrum disorder (ASD), create many significant life complications, some life-threatening. Applied Behavior Analysis (ABA) is established as an evidence-based approach to treat problem behavior for children with ASD and shows promise as an effective treatment for adults, yet little research has been conducted within the adult population. Assessment and treatment of problem behavior with adults is often challenging due to funding limitations, increased severity and complexity of problem behavior, and underqualified staff. The purpose of the present study was to overcome these challenges by (1) identifying a …

Tracking Keywords In American Studies, Thomas Cleary

Dissertations, Theses, and Capstone Projects

Tracking Keywords in American Studies is a computational text analysis project that provides interactive data visualizations which allow for deeper analysis of issues and discourses in the American Studies journal American Quarterly. Taking inspiration from Keywords for American Cultural Studies, which provides a list of keywords to serve as an entry point into understanding American Studies, my project takes these keywords and plots their occurrence throughout American Quarterly. Complimentary to the word counts, I chart algorithmically generated topics produced using topic modeling to look at discourses in the journal. This offers a different perspective on American Studies than …

How Much Does Imprecision In Accounting Measurement Enhance Value?, Ying Liang

Dissertations, Theses, and Capstone Projects

Theory on real effects suggests that more precise accounting does not necessarily improve investment efficiency. However, with investment efficiency mostly unobservable, empirical assessment of the theory is rare. This paper develops an empirical framework based on Kanodia et al. (2005) to structurally estimate the effect of imprecision in accounting measurement on investment efficiency. My estimates suggest that imprecision in accounting measurement has mitigated over-investment in capital expenditures and R&D by 28.6% and 4.9%, respectively. On average, firms still over-invest relative to the first-best full-information benchmark. In counterfactual analyses, my estimates suggest that the optimal investment efficiency could be achieved by …

Bones, Burials, And The Riddle Of Truth: Reconstructing The Past Through What Has Been Left Behind, Jelena M. Begonja

Dissertations, Theses, and Capstone Projects

Mortuary archaeology is known to be the study of human remains and burials. The primary focus of this work has been to study all of the elements associated in burials to learn more about the burial practices and rituals in a group’s culture, however, there is much more potential in studying burial sites than just learning about a group’s burial rituals and practices. This thesis will demonstrate that it is indeed possible to make different inferences about the rest of people’s daily lives, and the truth, based from materials found in studying burials alone. For some groups without much existing …

Analysis Of Autism Spectrum Disorder And Attention Deficit/Hyperactivity Disorder: Pharmacological And Non-Pharmacological Treatment Options, Amanda C. Dominguez

Dissertations, Theses, and Capstone Projects

There has been an increase in the diagnosis of neurodevelopmental disorders over the past decade, as shown by multiple studies. A particular interest has been on disorders that afflict children at an early age and persist throughout their life, such as Autism, now known as Autism Spectrum Disorder (ASD) and Attention Deficit and Hyperactivity Disorder (ADHD), previously referred to as Attention Deficit Disorder (ADD). The impact of these disorders has instigated extensive research into their signs and symptoms, causes and risk factors, diagnosis in terms of available diagnostic tools and processes, available treatment options, conventional and unconventional, as well as, …

Doing Away With Defaults: Motivation For A Gradient Parameter Space, Katherine Howitt

Dissertations, Theses, and Capstone Projects

In this thesis, I propose a reconceptualization of the traditional syntactic parameter space of the principles and parameters framework (Chomsky, 1981). In lieu of binary parameter settings, parameter values exist on a gradient plane where a learner’s knowledge of their language is encoded in their confidence that a particular parametric target value, and thus grammatical construction of an encountered sentence, is likely to be licensed by their target grammar. First, I discuss other learnability models in the classic parameter space which lack either psychological plausibility, theoretical consistency, or some combination of the two. Then, I argue for the Gradient Parameter …

Where Do We Go From Here? Québécois Identity In The Road Novel From 1964 To 2008, Antoinette Williams-Tutt

Dissertations, Theses, and Capstone Projects

Made famous with American of French-Canadian origin Jack Kerouac’s On the Road (1957), the road novel genre typically expresses evolving values and beliefs through the lens of the lone adventurer, embarking on journeys that are not only spatial but also social and cultural. The Québécois road novel adapts and reinterprets the American model, moving its protagonists within and without the province to address the deep-seated questions of Québec’s identity and nationalism through confrontations with the past, loss, grief, family, and cultural others. Car travel and cultural border crossings allow the protagonists to achieve a complicated individual and collective autonomy in …

Narrating Intensity: History And Emotions In Elsa Morante, Goliarda Sapienza And Elena Ferrante, Stefania Porcelli

Dissertations, Theses, and Capstone Projects

This dissertation examines the representation of emotions in My Brilliant Friend and in two Italian novels written between the 1960s and the 1970s – La Storia (1974, History: A Novel) by Elsa Morante (1912-1985) and L’arte della gioia (The Art of Joy, 1998/2008) by Goliarda Sapienza (1924-1996). However, rather than remaining centered on these works’ emotive landscapes alone, I seek instead to trace the continuities that link these two “historical” novels of the past to Ferrante’s successful and more recent tetralogy. I look at the representation of emotions and at what I call “moments of intensity” – …

Characterizing Surface Water From Space With Microwave Remote Sensing: Advancing Conventional And Emerging Approaches, Katherine Jensen

Dissertations, Theses, and Capstone Projects

The extent and dynamics of land surface inundation vary tremendously across the globe. Accurate spatial representation of terrestrial surface water is of critical importance for management and conservation of biodiversity and other ecosystem services associated with freshwater. Furthermore, surface water maps representing dynamic characteristics of inundated areas are also valuable for the development of wetland inventories and to assess the role of wetlands as major natural sources of methane to the atmosphere. Despite the importance of these environments in global processes and to current and future climate, the extent and dynamics of global wetlands remain poorly characterized and modeled.

Structural Studies Of Peptide Toxins And Their Binding Properties Towards The Voltage Sensing Domain Of Nav1.7, Ryan Schroder

Dissertations, Theses, and Capstone Projects

Voltage gated sodium channels (VGSCs) are essential to the propagation of nerve cell impulses and thus communication in the nervous system. VGSCs are comprised of four repeating units of six transmembrane helices. Of the six transmembrane helices, the first four (called S1-S4) comprise the voltage sensing domain (VSD) and the last two (S5-S6) comprise the pore domain (PD)¹. The Human voltage-gated sodium channel Na_V1.7 has been shown to play a vital role in the nerve pathways that induce pain response². Many of the currently available pain therapeutic drugs are opiates, derivative molecules of opium. …

Un Trust Funds As Agent To Fulfill The Norm Adapting And Diffusing Functions, Mikiko Sawanishi

Dissertations, Theses, and Capstone Projects

This thesis focuses on existing large-scale general trust funds at the United Nations (UN) Secretariat, as one example of the important transformations of the UN. They were created around the 1990s amid a paradigm shift in international relations after the end of the Cold War. They function as autonomous entities to carry out specific mandates to tackle emerging global issues in responding to the requests of a limited number of UN member states that provide voluntary contributions of significant sum. The thesis explores answers to the questions of why such general trust funds were created within the UN Secretariat, and …

Applications Of Machine Learning And Deep Learning In Macroeconomic And Financial Forecasting, Andi Cupallari

Dissertations, Theses, and Capstone Projects

This dissertation consists of three chapters.

In the first chapter I propose a novel approach to forecast risk premia selecting relevant predictors among hundreds of correlated stock characteristics. I adapt a recently developed method from the deep learning literature, Deep Neural Networks with Group Lasso Regular- ization. This method achieves high out of sample R2, and at the same time yields a sparse representation of the characteristics space that allows for interpretability of the otherwise black box deep learning model. For each period, the model chooses a subset of characteris- tics to be relevant for the risk premia forecast. Our …

Essays In Macroeconomics Of Emerging Markets, Miguel Acosta Henao

Dissertations, Theses, and Capstone Projects

Chapter 1. Law enforcement and the size of the informal sector.

I assemble new cross-country evidence showing that contrary to the standard view, the relationship between the size of the informal sector and tax rates is, at best, ambiguous. Law enforcement and informality also show no clear relation. Motivated by these findings, I augment a standard two-sector (formal and informal) small open economy model with endogenous law enforcement that depends on the size of the informal sector (measured by its assets) and government expenditure. I use a micro-dataset from Colombia to show that both taxes and law enforcement are necessary …

Shadow Standards And The Logic Of Costs: Care, Stewardship, And Data In U.S. Community Health, Margarite J. Whitten

Dissertations, Theses, and Capstone Projects

This dissertation examines the delegation of responsibility for providing health care to particular categories of marginalized populations in the United States in the absence of a uniform and universal health care system. It explores how the U.S. federal government governs patient populations at a distance by mandating that healthcare providers collect, produce, and report on patient data. Drawing from eighteen months of ethnographic research in Massachusetts clinics for the homeless and the frail elderly between 2014-2015, I argue that when marginalized patients are unable to satisfy the neoliberal ideal of self-governance to maintain their health in cost-effective ways, providers are …

Essays On The Education Production Function, Daniel Dench

Dissertations, Theses, and Capstone Projects

This dissertation consists of three chapters which test interventions along several dimensions of the education production function. In chapter one, I run a field experiment comparing the effect of two interventions, (1) an email nudge telling students similar problems to their homework will be on the exam and (2) grading the homework, on attempting homework. I find both interventions increase homework attempts: nudging by 3 percentage points and grading by 72 percentage points. Instrumenting for the effect of attempting the homework using grading, I find that attempting problems from the homework leads to an increase in the probability of getting …

Transgender In College: Engaging Marginalized Collegiate Students, Lo Ferguson

Dissertations, Theses, and Capstone Projects

In an educational structure not built for marginalized students how can inequality be counteracted within the system itself? Specifically, what are the best practices to engage and empower transgender students within student involvement and leadership on college campuses, specifically through engagement within the Office of Student Life? This thesis theorizes that practices that are inclusive and respectful to transgender students creates climates that engage and retain them. It will establish an understanding of the basics of what being transgender means, discrimination that impacts this community, and reviewing the transgender collegiate experience. These cumulative aspects of the transgender experience will prove …

Returning To Childhood: Memoirs Of Childhood Reading, Stephanie Montalti

Dissertations, Theses, and Capstone Projects

This thesis analyzes Francis Spufford’s The Child that Books Built: A Life in Reading, Jane Sullivan’s Storytime: Growing up with Books, and Margaret Mackey’s One Child Reading: My Auto-Bibliography to investigate how memoirists recall events and reread stories from childhood. I argue that memoirs of childhood reading or bibliomemoirs temporarily fuse childhood and adulthood through the act of rereading, which produces emotional responses, and writing a memoir. By rereading childhood stories, memoirists identify with their child self and express feelings comparable to those they felt upon first reading. In bibliomemoirs, passive and active reading create what I describe as a …

Behavioral Outcomes In Children With Autism Spectrum Disorder And Cochlear Implants, Patricia K. Herz

Dissertations, Theses, and Capstone Projects

The purpose of this literature review was to establish what is currently known about behavioral outcomes of children with Autism Spectrum Disorder (ASD) and cochlear implants (CIs). Sixteen articles were included in this review. The areas investigated were behavioral changes postimplantation, as determined by subjective and objective measures, mode of communication used by children with ASD and CIs, and effects of additional comorbidities on these outcomes. Considerations for CI use for children with ASD include potential hypersensitivity to auditory stimuli, inability to complete performance measures, and markedly slower progress than their typically developing peers. Many of the studies included in …

Essays In Retirement Economics, Gunnar Poppe Yanez

Dissertations, Theses, and Capstone Projects

This dissertation consists of three chapters.

Chapter 1

The discrepancy between the high demand for annuities predicted by economic theory and the empirical low holdings of these assets, known as the annuity puzzle, is still not completely understood in economic studies of retirement finance. This paper assesses the effect of individuals' mortality risk learning process on annuitization. I isolate this effect by building a life-cycle model in which individuals have imperfect information of their true survival probability distribution, and therefore have to update their beliefs about it in a Bayesian manner. Using data on subjective mortality by the Health and …

Essays In Financial Economics And Applied Macroeconomics, Marius Mihai

Dissertations, Theses, and Capstone Projects

This dissertation consists of three chapters that cover topics in finance and macroeconomics.

Chapter 1 - Do Credit Booms Predict U.S. Recessions?

This paper investigates the role of bank credit in predicting U.S. recessions since the 1960s in the context of a bivariate probit model. A set of results emerge. First, credit booms are shown to have strong positive effects in predicting declines in the business cycle at horizons ranging from six to nine months. Second, by isolating the effect of credit booms, I identify their contributions to recession probabilities which range between three and four percentage points at a …

And Ain’T I A Man: An Examination Of Violence Against African-American Men By Caucasian Men In The United States, Bryan L. Greene

Dissertations, Theses, and Capstone Projects

Various scholars, particularly feminist scholars of color, have examined the experiences of women in the realm of violence perpetrated by men, particularly Caucasian/white men against women of color. Critical Race Theory has proven beneficial to discussing violence perpetrated by Caucasian men in the United States against various communities of color broadly. Using these two premises, this thesis seeks to bring into the conversation the subjugation of men of color by white men. By looking at classical theories concerning the dualities that people of color encounter and struggle with along with womanist theories of feminism, this thesis seeks to spark a …

Promoting The Consumer Citizen: Seals, Spectacles, And The Gendered Consumer In Depression-Era America, Danielle B. Wetmore

Dissertations, Theses, and Capstone Projects

This thesis will argue that New Deal legislation accounted for increased importance placed on consumers and the articulation of consumer citizenship as female during the Great Depression. Once New Deal programs and legislation determined and legitimized the consumer citizen, the consumer citizen exercised influence though purchasing power. Analyzing the ways the federal government defined women as consumer citizens through programs like the National Recovery Administration’s Blue Eagle Campaign offers important insight into who was considered to have a voice. Notions of citizenship define groups by who has the necessary attributes and qualifications—in this case the means to purchase goods—to be …

Building For Culture: How Municipal Ownership Of Cultural Facilities Influences Annual Arts Funding In American Cities, Adam M. Sachs

Dissertations, Theses, and Capstone Projects

This thesis explores how local government support for arts and culture varies across 24 American cities. It has proven to be challenging for researchers to accurately measure municipal arts support. Research on cultural policy has also often focused on the federal level, despite total city expenditures far exceeding national or state government support. This thesis attempts to take an accurate pulse of city expenditures in 2017 and correlates those spending levels to the variation in city ownership of arts facilities. Rooted in the historical perspectives of the ‘new institutionalism’ and path-dependency, this paper argues that past decisions about taking ownership …

Jumping Into The Cloud: Privacy, Security And Trust Of Cloud-Based Computing Within K-12 American Public Education, Erik Carl Bennett

Dissertations, Theses, and Capstone Projects

The purpose of this study is to gain a deeper understanding of how faculty view Cloud-based computing, how they perceive issues of privacy, security, and trust when using Cloud-based systems in schools, and what differences, if any, exist between their at home use of Cloud-based computer systems and their use of these and similar systems at work. Educators who took part in this study (a) demonstrated a relatively good understanding of the Cloud; (b) perceived the issues of privacy, security, and trust as related to Cloud-based computing as a serious matter, which strongly influenced their acceptance of the Cloud, and …
