The Intersectional Perspective On Women And Girls With Disabilities: A Comparative Analysis, Kathryn F. Guzmán

Dissertations and Theses

People, including women and girls with disabilities have faced oppression and exclusion in society for centuries due to negative beliefs, stereotypes and attitudes that have led to stigma, discrimination and lack of support for them. For women and girls in particular, having a disability has historically meant that they were no longer considered beautiful and were seen as being incapable of meeting social and cultural expectations like marriage and motherhood. In recent decades, however, some progress has been made towards combating disability-based discrimination and promoting inclusion and full participation in society. Additionally, the adoption of the United Nations Convention on …

Analyzing Ultrastructural Characteristics Of Post-Synaptic Targets Of Pre-Identified Presynaptic Boutons In Layer 3 And Layer 4 Of The Ferret Primary Visual Cortex, Donia Shehab

Dissertations and Theses

The purpose of this study was to analyze the size and ultrastructural characteristics of post-synaptic elements apposed to previously characterized pre-synaptic elements in layers 3 and 4 of the primary visual cortex (PVC). We are aiming to quantify a range of values for synaptic element morphologies as well as to correlate pre- and post-synaptic elements to find a set of rules that is prevalent in the visual cortex that can also be upheld in other mammals. We hypothesize that bigger pre-synaptic elements correlate to bigger synapses and bigger post-synaptic elements. We compared these two different layers because they receive synaptic …

The World’S Leading Regulator: Why Countries Must Abide By The European Union’S Strict Chemical Laws And What That Means For Its Closest Trading Partners, Matthew Silberger

Dissertations and Theses

The European Union is the world’s leading regulator, imposing strict laws on all sectors of industry including chemical manufacturers. The bloc’s programs imposing these strict chemical regulations are entitled Restriction of Hazardous Substances Directive (RoHS) and Registration, Evaluation, Authorization and Restriction of Chemicals, or REACH. These laws are imposed to ensure that the chemicals present in products are properly recorded and to ensure the health and safety of citizens and the environment. This thesis will discuss the role the European Union plays in the world regarding the chemical industry and how countries modify their own regulations to ensure their companies …

Transition To Turbulence And Relaminarization Of Pulsatile Pipe Flows, Joan Gomez

Dissertations and Theses

The instability and transition to turbulence and its evolution in pulsatile pipe flows involving both, reverse and no-reverse flows, is the primary focus of this experimental work. A piston driven by a programable DC servo motor was used to set up a water flow system and provide the pulsation characteristics. Time-resolved particle image velocimetry data were acquired in a refractive index matching setup by using a continuous wave laser and a high-frame-rate digital camera. The position of the piston was continuously recorded by a laser proximity sensor. Different experiments were carried out with Reynolds numbers in the range of 535 …

Military Industry And The Israel-Palestine Conflict: Military Aid, Technology, And Barriers To Peace, Brandon A. Sandoval

Dissertations and Theses

This study reviews the current US and Israel militarized response to Palestine, the negative impacts on the Palestinian and Israeli people that result from this policy, and the military-industrial complex that benefits from the US-Israel relationship. I also note that the military industry profits from the Israel-Palestine conflict and, thus, has an incentive for the conflict to continue. I argue that despite billions of US dollars that have been appropriated by the U.S. Congress for Israel’s security, the US and Israel have failed to build peace in the region, ultimately wasting funds and exacerbating current conflicts. I also argue that …

Analysis Of Uncertainty In Hydrometeorological Ensemble Forecasts, Carolien N. Mossel

Dissertations and Theses

Ensemble hydrometeorological forecasting has great potential for improving flood predictions and use in water management systems, however, the amount of data used and created with an ensemble forecast requires a careful and intentional approach to understand how useful and skillful the forecast is. The NOAA National Water Model (NWM) was run using downscaled NOAA Global Ensemble Forecast System (GEFS) meteorological forcings for the 2016-2017 wet season (October-March) in California to create an 11-member hydrologic forecast ensemble. To evaluate the performance of these ensemble forecasts, we chose to study streamflow sites within Sonoma County, California, a rain-dominated region which includes the …

‘A Contradiction In Essence’: Eroticism And The Creation Of The Self In Henry Miller, Cian Doyle

Dissertations and Theses

The intention of this paper is, in the first, to demonstrate that Miller’s work has been labeled ‘erotic’, and that this obscures the true contribution of his work – but that as much as it obscures his work, this label also provides us an avenue to access it. In the second, it is to explore what actually constitutes the ‘erotic’, how this is featured in Miller’s work, and how it functions as an analytic tool to reveal what is significant in that work. Lastly, with specific regard to the works Tropic of Cancer and Tropic of Capricorn, the intention …

Protecting Civilians In Un Peace Operations: The Need For Enhanced Training, Allison S. Haddad

Dissertations and Theses

The present study shows that the protection of civilians (POC) tasks implemented in multiple United Nations (UN) peace operations have not always been executed as intended and, as a result, are accompanied by a number of dysfunctions. Among these dysfunctions are inadequate community engagement, peacekeeper misconduct stemming from the lack of proper training mechanisms, and lack of resources. In consideration of these issues, UN peace operations would profoundly benefit from enhancements offering plausible and beneficial change to the field. Such changes involve the responsibility of the UN, the responsibility of national actors, field implementations, and the psychological well-being of peacekeepers. …

Exploring A Mediational Model Of The Relationship Between Skin Color And Mate Selection In Desi Young Adults, Rabiya Ahmed

Dissertations and Theses

Skin color bias is present in South Asia and is especially apparent within the Desi (i.e., South Asian) marriage market, where explicit preferences for fair-skinned marital partners are made and lighter skin is perceived as more attractive. It is also known that, through the halo effect, attractive people are perceived to possess positive personality traits. The present study aimed to determine if skin color is associated with long-term mate preference among U.S.-based Desi adults as it is among Desi in South Asia, and if so, if that relationship is mediated by perceived attractiveness. It also aimed to determine if, in …

Addressing Gender Stereotypes In Egypt And The Impact Of Gender-Based Violence In Film And Media, Mayar Shoaeib

Dissertations and Theses

Social behavior is constructed through values, traditions, and culture that influence film and media. Film and media are products of the culture; film is an art form. Media are platforms for expression of values, traditions, and culture. Storytelling conveys the attitudes of a society and transmits them from one generation to the next. Using Egypt as a case study, I will highlight the importance of film and media in changing social behavior; specifically, this study will show that gender-based violence in Egypt can be attributed to trends in film and media. The representation of women in film and other media …

Adsorption Kinetics And Phase Behavior Of Particles Adsorbed At An Interface, Shaghayegh Darjani

Dissertations and Theses

The ability to predict the adsorption dynamic, phase behavior, and surface pressure of a monolayer of adsorbed particles in two-dimensional systems are key aspects of many current research areas. Examples include phase transitions in amphiphilic monolayers, emulsion stability due to particle adsorption at interfaces, and melting at an interface.

In this thesis, a new approach for deriving the equation of state for a two-dimensional lattice gas is proposed, based on arguments similar to those used in the derivation of the Langmuir-Szyszkowski equation of state for localized adsorption. This work aims to predict the adsorption kinetics and phase behavior of a …

Restoration Of Bone Material And Microstructural Properties After Long-Term Remodeling Suppression, Abigail A. Coffman

Dissertations and Theses

Anti-resorptive drugs, principally bisphosphonates (BPs), are the mainstay of osteoporosis treatment. They work by inhibiting bone resorption/remodeling, thus preventing bone loss. However, long-term suppression of bone resorption adversely affects bone tissue mechanical properties, even while conserving bone mass. Lack of remodeling leads to accumulation of fatigue-induced microdamage, altered matrix mineralization and reduction in normal bone tissue heterogeneity, causing impaired strength and fracture toughness. The most severe consequence to patients, while rare, is Atypical Femur Fractures (i.e., complete fatigue fractures of the femoral shaft). To counteract the effects of long-term remodeling suppression, a temporary break in BP treatment (a "drug holiday) …

A New Mathematical Theory For The Dynamics Of Large Tumor Populations, A Potential Mechanism For Cancer Dormancy & Recurrence And Experimental Observation Of Melanoma Progression In Zebrafish, Adeyinka A. Lesi

Dissertations and Theses

Cancer, a family of over a hundred disease varieties, results in 600,000 deaths in the U.S. alone. Yet, improvements in imaging technology to detect disease earlier, pharmaceutical developments to shrink or eliminate tumors, and modeling of biological interactions to guide treatment have prevented millions of deaths. Cancer patients with initially similar disease can experience vastly different outcomes, including sustained recovery, refractory disease or, remarkably, recurrence years after apparently successful treatment. The current understanding of such recurrences is that they depend on the random occurrence of critical mutations. Clearly, these biological changes appear to be sufficient for recurrence, but are they …

A Snowball Effect: A Pandemic’S Impacts On Household Food Insecurity In The United States, Sidie Sahid Sisay

Dissertations and Theses

Economic insecurity exists whenever income sources are uncertain, and this is a failure of a fundamental human right. The Covid-19 pandemic has presented unprecedented disruptions to the US economy and has created unparalleled food insufficiency and economic hardships. Before the pandemic, household food insufficiency existed but downplayed in the political arena. In 2019, 10.5 percent of households in the US lived in extreme poverty and were food insecure, the lowest since 1959, but the pandemic has had devastating effects on household food insufficiency. This paper uses nationally representative data from the Census Bureau’s weekly household pulse survey, coupled with standard …

Goes-R Supervised Machine Learning, Ronald Adomako

Dissertations and Theses

The GOES-R series is a product line of four satellite, with two currently on-orbit (GOES-16 “East” and GOES-17 “West”). GOES-17 is susceptible to a Loop-Heat-Pipe (LHP) phenomenon where during Fall and Spring seasons, there are times of day where some of the infrared bands records inaccurate readings from the Advanced Baseline Imager (ABI). This occurs from joint astronomical behavior and position of the GOES-17. This calibration issue occurs when the LHP instrument fails to radiate the heat of the sun out of ABI. Predictive Calibration (pCal) is an algorithm developed by instrument vendors for the National Oceanic Atmospheric Agency (NOAA) …

Blockchain-Based Architecture For Secured Cyberattack Signatures And Features Distribution, Oluwaseyi J. Ajayi

Dissertations and Theses

One effective way of detecting malicious traffic in computer networks is intrusion detection systems (IDS). Despite the increased accuracy of IDSs, distributed or coordinated attacks can still go undetected because of the single vantage point of the IDSs. Due to this reason, there is a need for attack characteristics' exchange among different IDS nodes. Another reason for IDS coordination is that a zero-day attack (an attack without a known signature) experienced in organizations located in different regions is not the same. Collaborative efforts of the participating IDS nodes can stop more attack threats if IDS nodes exchange these attack characteristics …

When The Brain Plays A Game: Neural Responses To Visual Dynamics During Naturalistic Visual Tasks, Jason Ki

Dissertations and Theses

Many day-to-day tasks involve processing of complex visual information in a continuous stream. While much of our knowledge on visual processing has been established from reductionist approaches in lab-controlled settings, very little is known about the processing of complex dynamic stimuli experienced in everyday scenarios. Traditional investigations employ event-related paradigms that involve presentation of simple stimuli at select locations in visual space and discrete moments in time. In contrast, visual stimuli in real-life are highly dynamic, spatially-heterogeneous, and semantically rich. Moreover, traditional experiments impose unnatural task constraints (e.g., inhibited saccades), thus, it is unclear whether theories developed under the reductionist …

Molecular To Macroscopic Understanding Of Chloroaluminate Anion Intercalation In Rechargeable Aluminum-Graphite Batteries, Jeffrey Xu

Dissertations and Theses

Today’s global energy challenges pose an urgent need to electrify transportation and better store intermittent renewable energy sources (e.g., solar and wind energy). For such large-scale battery applications, aluminum batteries are a promising “beyond lithium-ion” technology due to the high volumetric capacity, earth abundance, low-cost, and inherent safety of aluminum metal. However, there are very few compatible positive electrode materials that exhibit high energy density and cycling stability, in part due to the challenges of electrochemically intercalating highly charged Al³⁺ cations. Recently, graphite has been demonstrated as a promising positive electrode material in non-aqueous rechargeable aluminum batteries, which store …

Molecular-Level Understanding Of Ionic & Electronic Charge Storage Mechanisms In Rechargeable Aluminum Batteries Using Sold-State Nmr, Ankur Lahanu Jadhav

Dissertations and Theses

Rechargeable aluminum-ion batteries are safe and low-cost alternatives to traditional lithium-ion batteries due to the high volumetric capacity (8040 mAh/cm³) of aluminum. However, very few electrode materials have shown reversible aluminum ion intercalation. Intercalation Al³⁺ ions in these structures leads to poor capacity retention, mainly due to slow solid-state diffusion of the highly charged tri-valent aluminum ions within these crystalline structures. In 2015, aluminum ions were shown to reversibly intercalate/de-intercalate into the Chevrel Mo₆S₈ phase, though the intercalation mechanism is not well understood. Alternatively, molecular chloroaluminate ions within the ionic liquid electrolyte have also …

Understanding The Effect Of Climate And Hydrometeorological Extremes On Natural And Human-Induced Hydrosystems, Jeongwoo Hwang

Dissertations and Theses

The contemporary hydrosystems of the United States involve a complex combination of natural and modified basins in the presence of changing climate and anthropogenic impacts. An enhanced understanding of the interdependence between climate forcings, human-induced interventions, and water balance in both natural and modified basins are essential for developing reliable and resilient hydrosystems and for better water resources management. In response, this dissertation focuses on investigating the hydroclimatology of natural and modified basins across the contiguous United States. It has three research objectives: (1) to explain flow alterations due to anthropogenic activities, especially dam operations, in modified basins and understand …

Long Term Nutrient And Chlorophyll A Dynamics Across Long Island Sound And Impacts On Dissolved Oxygen Conditions Within The Western Sound (1991-2019), Sherry Perreira

Dissertations and Theses

Nitrogen overload, eutrophication, and hypoxia have been challenging and persistent water quality problems in Long Island Sound (LIS) over the past decades with major impacts on commercial industries, ecology, and recreational activities in the region. Recognizing these problems, the EPA enforced three phases of the Clean Water Act (CWA) to reduce nitrogen loads in an effort to improve this important estuary. This study examines how nitrogen (NH₃, NO_x & TDN), chlorophyll a (CHLA), and dissolved oxygen (DO) concentrations changed in LIS over the past 30 years, in response to water quality regulations as well as changes in …

Modern Dance, Embodiment, And Society: The Graham Technique’S Resistance To Conditioned Physicality, Cara Mcmanus

Dissertations and Theses

Martha Graham, foremost pioneer of American Modern dance, is the originator and developer of what is known today as the Graham technique. When this technique is removed from performative contexts, the philosophy of its practice can add insight to a discussion of embodiment and what it means to resist socially prescribed embodiments. This paper will examine the ways in which the Graham technique cultivates awareness of embodiment’s origins and processual nature, and therefore how a conscious resistance to social conditioning can arise. The neuroscientific and physiological processes behind this cultivation of awareness will be discussed, and several examples of resistance …

There’S More Than One Way To Beat The Heat: What Anal Probes Reveal About Thermal Responses In Neotropical Beetles (Coleoptera: Cerambycidae)., Emilie I. Dion

Dissertations and Theses

Increasing global temperatures have been linked to shifts in the distributions and preferred microhabitats of terrestrial species. This trend is predicted to impact tropical forest insects, which may already be exposed to conditions that bring them close to their thermal maxima. Tropical microhabitats are linked to vertical stratification, because the canopy is hotter, winder, and less humid than the ground. In ectothermic organisms, such as beetles, thermoregulation is dependent on morphological and behavioral traits. This study investigates woodboring cerambycid beetles, to determine how behavioral thermoregulation through microhabitat selection (vertical stratification) is correlated to morphological attributes (color lightness, size, and pubescence) …

On The Improvements Of Boundary-Layer Representation For High Resolution Weather Forecasting In Costal-Urban Environments, David Melecio-Vazquez

Dissertations and Theses

As large urban centers around the world become more densely populated, the global conversion from natural to man-made land surfaces will only increase. These land-use changes affect the urban surface energy budget which in turn changes the structure of the planetary boundary layer (PBL) above. With current high-performance computing systems, meteorological and built environment information can be better utilized to quantify the anthropogenic effects of these modifications. Although these systems have improved forecasting near-surface weather conditions, a comprehensive approach to represent urban impacts on the PBL is still limited. Improved PBL representation can lead to better weather and climate forecasts, …

The Crisis Of Chad: Men’S Rights Movements And Contemporary Anti-Feminism, Kendrick Zapata

Dissertations and Theses

This thesis analyzes the relationship between the modern incel and manosphere movement, and its historical legacies in anti-feminist discourses in late 20th century men's rights movements. The manosphere is a collection of online videos, forums, blogs, and websites dedicated to raising awareness or promoting masculinist philosophies. Incels in particular are individuals that understand their lack of sexual interaction as inherent, and often interact in digital spaces with others. Incel beliefs range from calling for the reversal of women’s rights, to seeking advice on self-improvement forums that offer advice to young men seeking to improve their physique through diet and exercise. …
