Green Is The New Black: Exploring How A Philosophical Approach To The Fashion Industry Will Reduce Its Environmental Impact, Darion A. Gibbs

Student Theses and Dissertations

The fashion industry is the third largest contributor to pollution globally, behind only oil and agriculture. It also accounts for one-fifth of the plastic produced annually. Despite its impact, it is hard to trace accountability. For example, mega-retailers often outsource production to developing countries, without strong structures of accountability for their environmental impact. In addition, companies often claim to be environmentally sustainable, but it is easy to inflate the truth, and entities designed to protect consumers have limited enforcement. In this context, who should be held responsible for the fashion industry’s contribution to climate change?

In response, this thesis delves …

Transport And Mixing Of Water Masses Across The Southeast Caribbean Ocean Imaged By Seismic Reflection Data, Joseph Renzaglia

Earth Sciences Theses and Dissertations

The Caribbean Sea serves as a major pathway for global thermohaline circulation (THC), which is a complex and vital component of the Earth’s climate system, influencing global heat distribution and oceanic circulation. Though relatively stratified, it is the boundary layer that distributes mass and temperature between the surface waters and the deep ocean where we observe various multiscale mixing processes from mesoscale to fine-scale. In regions where bathymetry is shallower and mechanical mixing forces, such as winds and tides, are more dominant, diapycnal diffusivity is typically stronger, driving vertical mixing. This type of mixing occurs at small scales, typically as …

Design And Fabrication Of A Low Power 7.2 Terabit Transmitter For Exascale Computing, Scott Mcwilliams

Electrical Engineering Theses and Dissertations

Enhanced Coupled Strength (ECS) gratings fabricated into III-V based devices offer high reflected power per unit length and broad band reflectivity as compared to conventional 1st order gratings, desired qualities for short-haul high speed transmitters that can be implemented without the need for chip-level temperature control, contributing to the low power per transmitted bit. For commercial DBR lasers, the grating reflectivity results in an extremely narrow reflectivity spectrum, which is highly desired for most/many applications, but requires a power hungry thermo-electric cooler to maintain a fixed frequency. The proposed LEAM (laser electro-absorption modulator) requires a broad reflectivity spectrum, which, by …

Camargo Guarnieri's Twenty Estudos: A Commitment To Brazilian Nationalism And Virtuosity, Steven Brancaleone

Dissertations, 2020-current

This document aims to find how composer Camargo Guarnieri uses Brazilian trends and incorporates them into his individual style, specifically in his Twenty Estudos for piano. The long compositional period of these pieces displays frequent experimentation and maturation in Guarnieri’s style between 1949 and 1988. The trends that Guarnieri follow can be traced by examining his life, environment, and teachings. Brazilian figure and instructor, Mario de Andrade, also contributes to molding and refining Guarnieri’s ideas. With this study, the Twenty Estudos will display Guarnieri’s individualistic use of Brazilian trends and how they correlate to his mature compositional style.

Distinguishing High-Quality Audio: The Unique Contribution Of Bit-Depth Resolution?, Benjamin Stone

Masters Theses, 2020-current

Individuals are capable of discerning high- and low-quality digital audio, but the current evidence tends to confound sampling rate and bit depth (see Mizumachi et al., 2014). When bit-depth is constant, higher sampling rates can be discerned (Oohashi et al., 2000). It likewise has been argued that 16- and 24-bit audio can be distinguished when sampling rate is constant (Kanetada et al., 2013). The present study aimed to evaluate bit-depth-related perceptual ability using simplified tone stimuli in order to determine at which point from 8- to 24-bit that further increases in bit-depth resolution are no longer perceptually beneficial. Potential contributions …

Neurobehavioral And Eeg Characteristics In Latino Targets Of Bullying, Isabel Solis

Psychology ETDs

Bullying adversely impacts the well-being and development of youth, calling for a comprehensive understanding of its neurobehavioral and social mechanisms for targeted interventions. Despite the increasing demographic of Latino children, little is known about their early life experiences and individual traits that leave them susceptible to becoming targets of bullying. The present study utilized a mixed-methods design to address this gap, incorporating interviews, neuropsychological assessments, and resting-state EEG (rsEEG) spectral power within the alpha (8-13Hz) and theta (4-7Hz) frequency bands. The aim was to compare the cognitive, emotional, social, and neural characteristics of nine Latino Targets (LT) of bullying and …

Modeling Lithographic Quantum Dots And Donors For Quantum Computation And Simulation, Mitchell Ian Brickson

Physics & Astronomy ETDs

Our first focus is on few-hole quantum dots in germanium. We use discontinous Galerkin methods to discretize and solve the equations of a highly detailed k·p model that describes these systems, enabling a better understanding of experimental magnetospectroscopy results. We confirm the expected anisotropy of single-hole g-factors and describe mechanisms by which different orbital states have different g-factors. Building on this, we show that the g-factors in Ge holes are suciently sensitive to details of the device electrostatics that magnetospectroscopy data can be used to make a prediction of the underlying confinement potential. The second focus is on designing quantum …

Exploring The Use Of Time Delay As A Pragmatic Cue In Text Messaging, Nicklas Phillips

Masters Theses, 2020-current

Text messaging is often used as a stand-in for face to face communication. While texting mimics the rapid back and forth, turn taking nature of oral conversation, it lacks many of the pragmatic cues conversationalists ordinarily rely on to establish common ground and inform their understanding of sometimes nonliteral meaning conveyed to them. To get around this hurdle, texters have developed sets of textisms. These are specific cues that can be used to make up for the lack of pragmatic information in the texting environment. Examples include emoji, emoticons, and punctuation. This is an experimental study exploring whether time can …

Sexually Transmitted Infection Prevalence In College Students With Urinary Tract Infection Symptoms: A Pilot Study, Kathleen Beigh

Doctors of Nursing Practice (DNP) Final Projects, 2020-current

Approximately one in five individuals in the United States has had a sexually transmitted infection (STI). Individuals between 15 to 24 years are considered a ‘higher risk’ for developing new STIs than other age groups. Many STIs are treatable but difficult to detect and carry significant health implications. Chlamydia and gonorrhea can be treated effectively with antibiotics if detected early. STIs are challenging to diagnose due to having few or no symptoms and often go undetected and untreated. A specific concern related to STIs is misdiagnosis as a lower urinary tract infection (LUTI) only in persons born with a vagina …

Heat & Social Cooperation: The Effects Of Thermal Stress On Altruism, Alexander J. Courtman

Master's Theses

Recent literature has highlighted the effects of temperature on economic outcomes and violence in humans, on both the interpersonal and intergroup levels: as temperatures rise, humans are more likely to exhibit increased aggression and agitation. However, little research has been done on how pro-social behaviors like cooperation and altruism among humans might respond to increased temperatures. As extreme heat events increase in frequency, will humans and communities work together in the face of adverse shocks and crises? Leveraging experimental data collected randomized controlled trails held in 4 locations across the world, this paper seeks to establish a relationship between thermal …
