Vertebrate Scavenger Diversity And Ecosystem Services Along An Elevational Gradient In Central Nepal, Aishwarya Bhattacharjee

Dissertations, Theses, and Capstone Projects

A growing number of studies recognize the ecological significance of vertebrate scavengers, and several species belonging to this diverse, functional guild are of high conservation importance around the globe. Studies on taxonomic and functional components of biodiversity often use elevation gradients to comprehensively examine patterns and drivers across multiple spatial scales. Yet, there are relatively few elevational studies on large vertebrates or multi-taxa guilds, and the related variation of their ecosystem services. In particular, scavenger research has largely focused on local-scale studies or regional/global comparisons of local-scale investigations. Moreover, these studies primarily consider taxonomic community characteristics and the patterns of …

Essays On Communication, Shawn M. Simpson

Dissertations, Theses, and Capstone Projects

One of the central issues of contemporary philosophy and biology is the nature of communication. Early accounts of communication tended to focus on just one side of the communicative divide – the speaker side or the receiver side – and took as their starting point the case of human language. Animal communication, historically, was largely treated as a special case. Now things are different. Now it appears we might have a model that makes sense of sign use in both the human and animal realms and brings together both sides of the signaling divide. It’s still to be seen, however, …

Redlining, Neighborhood Decline, And Violence: How Discriminatory Government Policies Created Violent American Inner Cities, Richard Powell

Dissertations, Theses, and Capstone Projects

Background – The practice of redlining involved the US government categorizing certain communities, often those inhabited by people of color, as too risky for private investment. Because of the resulting disinvestment, many of those neighborhoods deteriorated throughout the latter half of the 20^th Century. It also fostered conditions in redlined neighborhoods, such as high concentrations of poverty, joblessness, and racial segregation that the criminological theory of Social Disorganization identifies as correlates of violent crime.

Research Objectives – This study sought to determine whether redlining influenced levels of social disorganization operationalized as high levels of poverty, unemployment, family disruption, and …

The Role Of Tbx2 In Germ Layer Suppression And Dorsoventral Patterning During Early Vertebrate Development, Shoshana Reich

Dissertations, Theses, and Capstone Projects

The differentiation of the three primary germ layers is precisely regulated by inductive cues, the intracellular networks through which these signals are transduced, and a broad array of nuclear proteins, such as transcription factors and epigenetic modifiers. Precise regulation of these various factors is crucial to proper development. Members of the T-box family of DNA-binding proteins play a prominent role in the differentiation of the three primary germ layers. VegT, Brachyury, and Eomesodermin function as transcriptional activators, are expressed in the presumptive mesendoderm and, in addition to directly activating the transcription of endoderm- and mesoderm-specific genes, serve variously as regulators …

"Never Forget": Embodied Absence And Extended Relations Of Care After 9/11, Sophie L. Riemenschneider

Dissertations, Theses, and Capstone Projects

This dissertation is a reflection on how loss was articulated in the wake of 9/11. The terror attacks engendered a memorial style that sought to give shape to grief, acknowledging it without filling it in or erasing it. This new style, which I term embodied absence, exists across a range of mediums, from literature to architecture. It is such a potent memorial form because it also captures the traumatic process, which is prolonged, layered, and potentially open-ended. However, despite their ability to mirror the nature of trauma, instances of embodied absence never verbalize the attacks’ root trauma—the disconnect between our …

Salvatore Sciarrino's Sei Capricci For Solo Violin: Analysis And Performance Guide, Caroline Eva Chin

Dissertations, Theses, and Capstone Projects

This dissertation provides insight into the compositional and string techniques used in Salvatore Sciarrino’s Sei Capricci for solo violin. Each of the six chapters provides an analysis and performance guide for a caprice. A diagram of the score analysis for each caprice is included at the end of each chapter. In addition to the examination of Sciarrino’s original techniques for violin, caprices that make references to Paganini’s 24 Caprices for solo violin are discussed. Salvatore Sciarrino is an Italian composer (b. 1947) whose use of untraditional hushed sounds has become his signature compositional style. His innovative use of instrumental techniques …

Teaching For Transformation: Developing Agency And Solidarity Consciousness In A Critical-Transdisciplinary, Garden-Based Urban Environmental Studies Program, Pieranna Pieroni

Dissertations, Theses, and Capstone Projects

This dissertation focuses on “Community Roots,” an instantiation of urban, garden-based environmental education that employs a “critical-transdisciplinary” design framework and pedagogies. The “crit-trans” construct, articulated by the Urban Environmental Studies Research Coven (Strong et. al., 2016) is offered as both a generative approach to liberatory (environmental) pedagogies with applications across the curriculum and as a form of resistance to neoliberal logics shaping educational (and other) settings. After situating Community Roots in its socio-environmental, institutional, historical and theoretical contexts, a detailed description of the course’s instantiation of crit-trans pedagogy is offered. Additionally, reflections of 14 youth and adult participants are analyzed, …

Instrumentalizing The Past: The Politics Of Holocaust Memory In Contemporary Poland, Jonathan Zisook

Dissertations, Theses, and Capstone Projects

This study investigates Poland’s politics of Holocaust memory from the contentious Jedwabne debate in the early 2000s through the present and shows how the history of the Holocaust has been both distorted and exploited in contemporary Polish politics and culture. It pays special attention to the most recent period of Law and Justice Party rule (2015-2020) and considers the varying ways that the government has constructed its approach to the past by asserting a “policy on history” (polityka historyczna) in state-sponsored research, the educational system, legislation, museum narratives, and more. In so doing, this work argues that the …

Informed Consent: Foundations And Applications, Joanna Smolenski

Dissertations, Theses, and Capstone Projects

Since its advent in the 20th century, informed consent has become a cornerstone of ethical healthcare, and obtaining it a core obligation in medical contexts. In my dissertation, I aim to examine the theoretical underpinnings of informed consent and identify what values it is taken to protect. I will suggest that the fundamental motivation behind informed consent rests in something I’ll call bodily self-sovereignty, which I argue involves a coupling of two groups of values: autonomy and non-domination on the one hand, and self-ownership and personal integrity on the other. I will then go on to consider two 'case …

The Tale Of Two Countrysides: The Shaping Of Landscapes In Hispania And Spanish Latin America, Andrew R. Abrams

Dissertations, Theses, and Capstone Projects

The way that culture expands and transforms in a colonial context has often been viewed in a top-down approach. This thesis focuses on the spread of culture in the Roman conquest of Spain and the Spanish conquest of Latin America. By framing the argument with a discussion on Romanization, this paper shows the presence of the ideas surrounding Romanization in a new context. By investigating what material culture shows, this thesis looks to the countryside to find examples of cultural change. It argues that the villa landscape should be seen as the indicator of the Romanization of Hispania. The structure …

The Grid Elegies, Pamela A. Kallimanis

Dissertations, Theses, and Capstone Projects

Immigrants are a key component in New York City’s pandemic. Historically, New York is a city of immigrants and their children. In the latter part of the 20th Century, more immigrants arrived due to changes in migration policy. There was also an increased outmigration through second and third generations, which mirrors an economic trajectory seen in previous points in history, mainly in the 1970s. At that time, there was the lure of government policies – from federal mortgage agencies that graded white suburban areas as safer areas for banks to make loans than racially mixed urban areas, to road construction …

A Difference In Rhythm: John Burroughs As Rhythmanalyst, Jennifer Macdonald

Dissertations, Theses, and Capstone Projects

Nature writer John Burroughs wrote about the rhythms of life in nature, people, and places, sharing his experiences of his surroundings for readers to learn from, get inspired by, or escape through. In this literature review, using Henri Lefebvre’s Rhythmanalysis, in which rhythm is the “interaction between a place, a time, and an expenditure of energy” (Lefebvre, 2004, p. 15), I explore some of Burroughs’ writing, asserting that Burroughs himself was a rhythmanalyst. Burroughs is typically read as a literary naturalist who hoped to relay any scene as it truly was (to perfect the “art of seeing things” or …

Here Time Becomes Space: The Victorian Spatial Imaginary, Jonathan E. Rachmani

Dissertations, Theses, and Capstone Projects

My dissertation, “Here Time Becomes Space: The Spatiality of the Victorian Novel,” addresses the Victorian realist representation of space as the open zone of interaction where the circulation of affect among embodied subjects and the places and things in their environment challenges the individualist axis of Victorian plots. I envision this spatiality as a composite literary practice emerging from contact with eighteenth-century realism, the Gothic novel, and the radical revision of the social imagination under the Romantics. Through an analysis of major works by Charlotte Brontё, Charles Dickens, George Eliot, and Henry James, I trace the dialectical development of realist …

Contributions Of Reward Identity And Time Prediction Errors To Pavlovian Learning, Daniel B. Siegel

Dissertations, Theses, and Capstone Projects

Some models of associative learning attempt to explain effects such as blocking and unblocking as reflecting a prediction error (PE): Associative strength, and thereby learning, are said to be greater when the unconditioned stimulus (US) received following a cue deviates from one’s expectations. Some models of PE-motivated behavior and PE-relevant brain activity represent the US as a single quantitative variable for outcome value, and that learning therefore only occurs when outcome value differs from expectations. There is growing evidence to suggest that changes in other dimensions of reward, such as identity and timing, also contribute to learning. In Experiment 1, …

Quod Inane Vocamus: Lucretius’ Void In Seventeenth-Century Italy, Carlo Bottone

Dissertations, Theses, and Capstone Projects

During the seventeenth century, the revival of atomic theories and the beginning of barometric experiments sparked a philosophical debate on the existence and the nature of void, which in turn generated new attention to the ancient disputes on void and prompted new interpretations of Lucretius’ examination of inane (De Rerum Natura, I.329-397). Commentators began to discuss the passage beyond the ancient philosophical tradition and in relation to modern ideas and recent discoveries, while Vacuists appealed to Lucretian arguments to prove or deny the existence of an absolute void interspersed among corpuscles.

My research contributes to the scholarship on …

Some Notes On Birds: Language And Attention In The Age Of Social Media, Aimee Lamoureux

Dissertations, Theses, and Capstone Projects

Technology, social media, and its affiliated distractions are now an ever-present part of our daily lives. Attention is a commodity, one which tech companies value because it delivers them bigger and bigger profits. Their products are intentionally designed to be additive, to demand more and more of our time and attention throughout our day. However, attention is not simply a commodity, but the way in which we connect with the external world and attend to our everyday experience. The world that we create in the mind is the world that ends up forming the reality of our everyday lives. Complex …

Estrogen Modulation Of Vta Dopamine Neuron Physiology And Behavioral Responsivity To Variable Social Stressors, Mary R. Shanley

Dissertations, Theses, and Capstone Projects

The behavioral output of different animals, or even the same animal in different contexts, is remarkably variable in response to the same external stimulus. This behavioral diversity is due to the complex integration of external and internal stimuli, through both neuronal and hormonal signals that selects the best behavioral response. By their nature as long-distance signaling molecules, hormones play a critical role in communicating information about internal states across the organism. Many hormones produced in the periphery target the central nervous system to modulate animal behavior, selecting for behaviors that are appropriate over behaviors that are maladaptive in that specific …

Immigration Lawmaking, 1950–1986: Cold War Politics And Double-Edged Reforms, Benjamin Becker

Dissertations, Theses, and Capstone Projects

The dissertation is a study of immigration lawmaking in the Cold War period. It explores how the gap emerged between the law and the social reality of immigration, and how lawmakers politically and institutionally “resolved” these contradictions under the competing pressures of foreign policy, shifting Congressional alignments, an unstable economy and the reigning political idiom of non-discrimination.

The constant efforts to reformulate immigration policy from 1952 to 1990 were produced by the struggle between competing economic and political blocs in a context largely insulated from public opinion, where Cold War foreign policy demands set the boundaries of acceptable discourse and …

Reimagining Recovery: Debt, Mutual Aid, And Disaster Governance In Puerto Rico, Sarah Molinari

Dissertations, Theses, and Capstone Projects

This study analyzes the politics and lived experiences of debt and climate disaster recovery in Puerto Rico. It examines mutual aid and debt resistance in relation to governance techniques and overlapping crises marked by the U.S. territory’s bankruptcy, the aftermath of Hurricane Maria (2017), and culminating with popular mobilizations in the summer of 2019 that propelled the governor’s resignation. Tracing the ways that the post-hurricane social disaster and debt crisis are mutually constitutive, I investigate a case of women-led grassroots mutual aid organizing in the east-central municipality of Caguas, Puerto Rico and a political movement calling for a citizen audit …

Understanding The Influence Of Zinc On Grain Cadmium Accumulation And Bioaccessibility In Rice, Michael A. Tavarez

Dissertations, Theses, and Capstone Projects

The effect of cadmium and zinc on mineral concentrations in three cultivars of rice

Interactions between the essential mineral zinc (Zn) and the toxic heavy metal cadmium (Cd) play an important role in regulating transport of both minerals to rice grains. Understanding these interactions is crucial for limiting cadmium and increasing zinc transfer to the food chain. Previous studies on the matter have had conflicting results suggesting synergistic and antagonistic relationships between the minerals. The goal of this work was to identify the effect of external cadmium and zinc on the uptake and translocation of both minerals from roots to …

Apathy And Brain Atrophy During The First Year Of Moderate-Severe Traumatic Brain Injury: A Longitudinal Study, Gulnaz Kudoiarova

Dissertations, Theses, and Capstone Projects

Apathy, defined as disinterest and loss of motivation, is a common complication after moderate-severe traumatic brain injury (msTBI). The existing body of research in various neurological and neurodegenerative disorders suggests that apathetic symptoms may be associated with variation in the volume of the brain regions such as dorsal anterior cingulate cortex and ventral striatum. However, the longitudinal pattern of TBI-induced atrophy in these key regions and its relationship with apathy symptoms remain to be demonstrated. The current study aimed to describe the atrophy pattern in the anterior cingulate gyrus (ACG) and the nucleus accumbens (NAc; part of ventral striatum) after …

Analysis Of Transplantable Photoreceptor Replacement Cell Chemotactic Mechanisms In Retinal Biomimetic Ligand Gradients, Onyekwere Onwumere

Dissertations, Theses, and Capstone Projects

Disease or trauma induced loss of rod and cone photoreceptors is a major cause of vision loss worldwide. To replace lost photoreceptors and restore vision, laboratories around the world are investigating photoreceptor replacement strategies using subretinal injection of photoreceptor precursor cells (PPCs) and retinal progenitor cells (RPCs). A major obstacle in the field is that transplanted photoreceptor replacement cells exhibit extremely limited migration into host retina following injection into the subretinal space. In this work, we show that PPCs and host retinal interaction bioinformatics modeling can identify key pathways involved in photoreceptor replacement cell migration and invasion behaviors. In addition, …

How Frustration Impacts The Relationship Between Potential For Child Physical Abuse Perpetration And Emotion Processing, Amanda L. Zwilling

Dissertations, Theses, and Capstone Projects

Research conducted over the past 20 years has substantiated the serious, long-lasting impacts of child physical abuse (CPA) has on individuals, families, and society. Research has also suggested several appreciable risk factors for perpetration of CPA. Intergenerational transmission of abuse, described as the personal experience of abuse or neglect during childhood, is prominent in the literature as a predictor of subsequent perpetration of CPA. However, the majority of individuals who experience abuse in childhood do not subsequently engage in perpetration of child abuse as adults. As such, the literature has sought to investigate risk factors that mediate the relationship between …

The Influence Of Prosecutorial Overcharging On Defendant And Defense Attorney Plea Decision Making: Documenting And Debiasing The Anchoring Effect, Stephanie Aurora Cardenas

Dissertations, Theses, and Capstone Projects

Strategic overcharging, a practice that some prosecutors readily employ to threaten defendants with excessively severe sentences, undermines the Sixth Amendment right to trial by coercing defendants to plead guilty rather than face penalties disproportionate to their alleged misconduct. Legal scholars and psychologists have long suggested that strategic overcharging may elicit powerful anchoring effects that bias defendants’, but not attorneys’ evaluations, of the plea offer. The current research sought to examine (a) the extent to which mock defendants and legal professionals were susceptible to the anchoring bias, (b) elucidate the mechanism underlying susceptibility to the anchoring effect in plea contexts, and …

Dual Control Of One Component Signaling: Mechanistic And Structural Insights Into El222 Active States, Uthama Phani R. Edupuganti

Dissertations, Theses, and Capstone Projects

Photoreceptors play a crucial role in signal transduction as specialized proteins which sense light as environmental stimuli and transduce the signal to control of downstream functions. Here we focus our attention on one class of these proteins, the Light-Oxygen-Voltage (LOV) domain, which is sensitive to blue light via an internally-bound flavin chromophore. Since their initial discovery in plant phototropins, many details of their photochemistry, chromophore interactions, and use with a diverse set of functional effectors have been described. However, several key details, especially a comprehensive understanding of signaling mechanism and its regulation, still remain elusive due in part to the …

Development Of High-Throughput Methods For Screening Venom Peptides, Tanya Napolitano

Dissertations, Theses, and Capstone Projects

Bioactive venom peptides are increasingly being explored as drug leads in pharmaceutical research because of their immense therapeutic potential, however there is a need to more efficiently screen and characterize these peptides to discover medicinal leads more quickly.1,2 The Holford lab has leveraged recent technological achievements in genomics, transcriptomics, and proteomics to produce a leap in the discovery of venom peptides from previously hard to characterize small and neglected venomous animals such as Terebridae, an understudied lineage of the Conoidea Superfamily.4, 5–7 With the rise of -omic technologies the floodgates have opened and venom researchers are awash with large datasets …

The Federalist Papers' Account Of Human Nature, Jeffrey P. Smith

Dissertations, Theses, and Capstone Projects

This paper is an analysis of the account of human nature found in The Federalist Papers. This interpretation assumes The Federalist is a work of political rhetoric and advocacy, but also one of genuine significance as political science and philosophy. As a book, The Federalist is a coherent whole, which offers a coherent account of human nature, despite the collective nature of its authorship, the time pressures of its publication, and the piecemeal nature of its workmanship. This understanding of human nature is the thread which runs through all its analysis and numbers. Its arguments asserting the inadequacies of …

Food Restriction And Body Image Distortion In Pregnant Mothers: Outcomes For Exposed Children, Kathryn M. Dana

Dissertations, Theses, and Capstone Projects

Background: Developmental trajectories in the growing child do not originate at birth. Rather, critical periods may exist in pregnancy, during which the determinants of malnutrition are especially vulnerable to the effects of stress and other complications. Prenatal malnutrition has been consistently associated with negative consequences for the growth, development, and overall physical and mental health of affected offspring in both human and animal models. While most available literature on human prenatal malnutrition comes from famine research, there is some evidence that restrictive eating disorders in pregnant women may be associated with similar outcomes.

Hypotheses: We hypothesize that prenatal exposure to …

After Abstract Expressionism: Reconsidering The “Death Of Painting” At Midcentury, Natasha Roje

Dissertations, Theses, and Capstone Projects

The “death of painting” is a mantra repeated throughout the twentieth century, at once taken for granted and endlessly debated. This dissertation reconsiders the “death of painting” from the vantage point of the midcentury moment in the U.S. in order to challenge the notion that artists of this time had “killed,” objectified or dissolved painting into 1960s practices like performance and Minimalism. With Abstract Expressionism acting as the fulcrum between a historical paradigm in which painting was dominant, even synonymous with “art,” I focus on the work of three pairs of artists to understand how painting came to be considered …
