A Discrete Conley-Zehnder Index For Symplectic Polytopes, Yutian Yu

Electronic Theses and Dissertations

A Hamiltonian system is a dynamical system governed by Hamilton’s equations. Hamiltonian systems provide a framework for studying classical mechanics. One fundamental principle in Hamiltonian mechanics is the conservation of energy along the flow of the Hamiltonian vector field. The smooth hypersurface of a Hamiltonian function on a symplectic manifold has a contact structure, and the associated Reeb vector field is, up to a scale, the Hamiltonian vector field. We are interested in the non-smooth case and a symplectic polytope makes a good model to study.

In this dissertation, we study the Reeb dynamics on the boundary of a symplectic …

Voices From Below: The Politics Of Leprosy Control In Southeastern Nigeria, 1926-1960, Odinakachukwu Kingsley Eze

Electronic Theses and Dissertations

Leprosy was an endemic disease in colonial Southeastern Nigeria but became an epidemic between the 1920s and 1940s. Unlike malaria and sleeping sickness, its endemicity did not impede European penetration at the dawn of the twentieth century. However, its spread across Nigeria intensified during colonial rule, with acute prevalence in regions hitherto prone to the disease. Therefore, from the 1920s to 1960, Southeastern Nigeria became the epicenter of British policies tailored towards preventing, curing, and eradicating leprosy disease in Nigeria. Existing research has established the involvement of different actors in this course–including Christian missionaries, colonial officials, specialized agencies, and international …

Molecular Dynamics Simulations For The Mechanical Behavior Of Alpha Quartz With Void Defects Under Tension, Yu Jia

Electronic Theses and Dissertations

The structural and mechanical properties of void-free and single-void α-quartz were investigated using MD simulations with three different interatomic potentials (BKS, Vashishta and Tersoff). Two distinct ensembles, NVT and NPT, were separately applied to investigate the tensile response of α-quartz under uniaxial strain and uniaxial stress states. A comprehensive comparison among different potentials, as well as comparison with currently available experiments, has been made. The BKS and Vashishta potentials accurately predicted the structural properties of void-free α-quartz, while the Tersoff potential was deviated significantly from the experimental data. Under tension, the BKS did a better description for the mechanical performance …

Gender Differences And Directionality Of Intimate Partner Violence, Nate Juda

Electronic Theses and Dissertations

The academic discipline of intimate partner violence (IPV) is currently divided into two prevailing perspectives: the feminist perspective, which asserts IPV is a product of the long history of acceptance and encouragement of wife-beating, stemming from patriarchal values; and the gender-inclusive model, that finds IPV reflects multifunctional etiologies, across the types and severities of IPV, with both men and women as perpetrators and victims at similar rates. However, a review of the extant literature does not support either of these conclusions. There is a growing body of research evidence that suggest women are more likely than men to commit IPV. …

Bio-Inspired Memory Device Based Physical Reservoir Computing System To Solve Temporal And Classification Problems, Md Razuan Hossain

Electronic Theses and Dissertations

In recent years, technological advancements in the field of computing have been limited by the slowing down of Moore’s law, which predicts the doubling of the number of transistors on a microchip every two years. The limitations of traditional solid-state electronics have become increasingly evident, as it is becoming difficult to increase the number of transistors while maintaining their reliability and performance. The breakdown of Dennard Scaling, which describes the power-density relationship in CMOS transistors, and the von Neumann bottleneck, which refers to the limited bandwidth between the central processing unit (CPU) and memory, have further exacerbated the situation. Moreover, …

Investigating The Impact Of A Brief, High-Intensity Exercise Break During Prolonged Gaming On Esports Performance, Hannah E. Nelson

Electronic Theses and Dissertations

Previous research shows that mental fatigue leading to decreased cognitive functioning may occur after 2 hours of continuous activity. This decline could be detrimental to esports athletes that may play for 3 or more hours at a time. Use of a moderate-intensity exercise break following 1 hour of gaming did not improve cognitive functioning more than continuous play. Increases in blood glucose levels are typically related to increases in cognitive functioning. Therefore, research should be done to investigate the relationship between glucose levels and cognitive function during long-duration gaming and how the use of an active exercise break may impact …

Classic Maya Subadult Age Estimates From Ambergris Caye, Belize, Nikki Anne Wicox

Electronic Theses and Dissertations

Maya of the Classic period (300-900 AD) were inhabitants of the coastal island of Ambergris Caye, Belize (Guderjan, 2007). The individuals of this island have been explored through other research, however, one sub-population on the island that has yet to be explored in depth is that of childhood. Children play an integral role in society but are often overlooked as active members based upon the modern cultural norms of childhood, as well as the perceived difficulty of identifying children´s activities in the archaeological record (Ardren, 2015; Ardren & Hutson, 2006; Danforth, 1989; Storey, 1992; Wright, 1997). My research aims to …

How Does The Creation Of Temporary Wetland Habitat On Agricultural Fields In The Mississippi Alluvial Valley Affect The Abundance Of Migratory Shorebirds?, Emma Mccarley Counce

Electronic Theses and Dissertations

Although the causes of broad population declines of migratory shorebirds are not well understood, it is likely that loss of migratory stopover habitat is a contributing factor. In the Lower Mississippi Alluvial Valley (LMAV), much of the historical stopover sites have been converted to agricultural land. To combat this dearth, we have incentivized farmers to create temporary wetland habitat on shallowly flooded corn and soybean cropland in the LMAV during the fall after harvest. In a two-year study, shorebird surveys were completed bi-weekly on employed farm sites to determine the abundances of shorebirds present on five different temporal flood treatments …

“To Save My Own Life:” The Revisionary And Sustaining Practice Of Autotheory, Margaret Zee

Electronic Theses and Dissertations

Autotheory, a hybrid of autobiography and literary theory, is the term Paul B. Preciado used to describe his book Testo Junkie (2008), a term Maggie Nelson then borrowed as a label for her book The Argonauts (2015). Though the term autotheory is relatively new, such hybrid writing has a rich literary history which I trace to intersectional feminist writers like Audre Lorde, Gloria Anzaldúa, and bell hooks in chapter 1’s genealogy. I argue that autotheory participates in theory’s work even as it revises certain Theoretical assumptions that hold sway in the academy today. This dissertation names three contemporary American books …

A Demand-Side Theory Of Labor Informality: Workers' Trust And States' Credible Commitment, Julian Alfonso Acevedo Pardo

Electronic Theses and Dissertations

Labor informality is a vexing issue across Latin America, with negative implications for policy areas from economic growth to social safety nets. Despite decades of efforts by national governments and international organizations, informality levels remain stubbornly high across the region. Insights from the extant literature suggest informality arises because creating formal sector jobs is too costly or the costs of formality for workers are too high. In contrast to most previous works on informality, this project steps back from standard materialistic assumptions and aims to uncover how the overall relationship between states and citizens impacts workers' incentives to work formally. …

Successful Aging And Turnover Intention Among Older Hospitality Frontline Employees, Thamsanqa Jongile

Electronic Theses and Dissertations

This two-part dissertation delves into the intertwined precursors of successful aging and turnover intent in the hospitality sector. The first part applies a structural equation model to examine the link between perceived narcissistic leadership, successful aging, and turnover intentions. The author posits that work engagement, employee cynicism, and emotional fatigue are the mechanisms through which perceived narcissistic leadership affects successful aging and turnover intent. The findings affirm these conjectures, revealing that narcissistic leadership serves as a predictor of successful aging and turnover intent.

The second manuscript probes further into the antecedents of successful aging, evaluating a theoretical model in which …

Psychometric Properties Of The Spanish Ucla Ptsd Reaction Index For Dsm-5€“Brief Form In Puerto Rico Following Hurricane Maria, Evan Edward Rooney

Electronic Theses and Dissertations

Trauma exposure among youth is a significant public health issue and is associated with psychiatric symptoms and impaired functioning. Natural disasters, such as hurricanes, have become an increasingly salient source of traumatic exposures for youth. However, not all youth exposed to traumatic experiences go on to develop posttraumatic stress symptoms or other maladaptive reactions. Given the high need for psychological support and low resource context engendered by hurricanes, efficient and evidentiary tools for assessing risk are needed to effectively identify youth most in need of services. The present study will use a sample of 96,108 Puerto Rican youth (Grades: 3-12; …
