Computational Microscopy For Biomedical Imaging With Deep Learning Assisted Image Analysis, Yuwei Liu

Dissertations

Microscopy plays a crucial role across various scientific fields by enabling structural and functional imaging with microscopic resolution. In biomedicine, microscopy contributes to basic research and clinical diagnosis. Conventionally, optical microscopy derives its contrast from the amplitude of the optical wave and provides visualization of the physical structure of the sample qualitatively. To understand the function at the cellular or tissue level, there is a need to characterize the sample quantitatively and explore contrast mechanisms other than light intensity. Image enhancement or reconstruction from microscopic imaging systems is known as computational microscopy, and it involves the application of computational techniques …

Sensing With Integrity: Responsible Sensor Systems In An Era Of Ai, David Eisenberg

Dissertations

Deep and machine learning now offer immense benefits for consumer choice, decision-making, medicine, mental health and education, smart cities, and intelligent transportation and driver safety. However, as communication and Internet technology further advances, these benefits have the potential to be outweighed by compromises to privacy, personal freedom, consumer trust, and discrimination. While ethical consequences for personal freedom and equity rise from these technological advances, the issue may not be the technology itself but a lack of regulation and policy that allow abuses to occur. A first study examines how emerging sensor-based technologies, limited to only accelerometer and gyroscope data from …

Tightrope Walking: Balancing Theatre Teachers’ Academic Freedom Of Expression With The Implementation Of Florida’S Stop Woke Act And Don’T Say Gay Bill, Kimberly Adams

Barry Law Review

Florida’s Individual Freedom Act (IFA) and Education Equality Act (EEA), better known as the Stop Woke Act and the Don’t Say Gay bill, respectively, are contentious topics in the United States today. One side argues that parents have the ultimate right to choose what their child learns and how a teacher should deliver that instruction while believing that lessons that address systemic racism divide children and make them feel uncomfortable. The other side argues that our students will be unprepared when they graduate high school to contribute to our multi-racial society and will suffer from a limited worldview. From the …

Dobbs And Exit In Antidiscrimination Law, Marcia L. Mccormick

Employee Rights and Employment Policy Journal

In the last couple of decades, pursuit of what Robin West has called “exit rights” has played an increasingly important role in the development of antidiscrimination law. From religiously affiliated schools seeking to insulate employment decisions for employees through a judicially crafted ministerial exception, to corporate challenges to the Affordable Care Act’s contraceptive mandate using the Religious Freedom Restoration Act, employers have sought to escape the burdens of complying with legal protections for workers. The current wave of litigation seeks broad exemptions from antidiscrimination laws for two types of employers: for-profit businesses who wish to discriminate against employees based on …

Microplastic Abundance And Removal In Stormwater Using Green Infrastructure, Meghana Parameswarappa Jayalakshmamma

Dissertations

Microplastics (MPs) are increasingly recognized as a pervasive environmental contaminant, conveying other contaminants, accumulating in aquatic organisms, and posing ecological risks. The existing research has primarily focused on MPs in wastewater treatment plant effluents in surface waters. However, the role of stormwater systems in MP transport has been less explored. Given the rise in MPs from urban sources, stormwater runoff from urban areas may serve as a critical conduit for transporting land-based MPs into aquatic environments. Green infrastructures (GIs) have been recognized for mitigating flooding and improving water quality from minor storms by trapping stormwater pollutants. Yet, the capability of …

Morphometric Analysis And Taxonomic Re-Evaluation Of Pepsis Cerberus Lucas And P. Elegans Lepeletier (Hymenoptera: Pompilidae: Pepsinae: Pepsini), Frank E. Kurczewski, Akira Shimizu, Diane H. Kiernan

Insecta Mundi

Hurd (1952) separated Pepsis cerberus Lucas from P. elegans Lepeletier (Hymenoptera: Pompilidae: Pepsinae: Pepsini) based on external morphology and biogeography. Vardy (2005) synonymized the familiar and historically well-documented P. cerberus and P. elegans, combining these Nearctic taxa with several Neotropical variants in an extremely broad definition of P. menechma Lepeletier. In doing so, Vardy (2005) breached the principle of nomenclatural stability. He ignored the prevailing usage and clearly violated articles 23.2, 23.3 and 23.9.1.2 of the ICZN (1999). Morphological differences, ecological divergence, and narrow sympatric geographic distribution of P. cerberus and P. elegans …

Internet-Based Data Platforms Re-Define The Distributions Of Some Large Crabronid Wasps In Arkansas (Hymenoptera: Crabronidae), David E. Bowles

Insecta Mundi

The geographic distributions of three large wasps, Sphecius speciosus (Drury), Stictia carolina Fabricius, and Stizus brevipennis Walsh (Hymenoptera: Crabronidae), occurring in Arkansas are defined using museum specimens and three internet-based data platforms. The internet-based data platforms generally provided more county location records than museum records. Using data from internet sources for easily identified species can better serve to illustrate the known distributions for some species thus making for a powerful tool elucidating distributional patterns and conservation planning.

Legally Sanctioned Takings Of Black Children: How Slavery Reverberates In The Modern Child Welfare System, Abigail Mitchell

The Scholar: St. Mary's Law Review on Race and Social Justice

This article explores the link between the taking of Black children from their families perpetrated as part of American slavery and modern takings in the modern family policing system. This article posits that underpinning both systems is a pervasive paternalism that purports to be benevolent but has been weaponized to systematically traumatize Black children and villainize Black parents. This article takes a sweeping historical perspective and connects the same discourse used to justify slavery to that which has permeated the modern family policing system.

Women’S Routes: Gender, Mobility, And Knowledge Among The Makushi Of Southern Guyana, Lisa Katharina Grund

Tipití: Journal of the Society for the Anthropology of Lowland South America

Exploring the journeys of some Makushi women, this article highlights the relevance of gender in the question of (im)mobility and female engagements with the world as central to contemporary Makushi life. Departing from the understanding that the category of space has proven crucial in the theoretical groundwork of the Guiana ethnographic area and drawing on the region’s classical ethnographies, it explores everyday practices of movement of the Makushi people who live along the triple frontier of southern Guyana. Rather than disruptive, these in and out journeys—collective or individual—prove to be crucial to the weaving of community. They are also central …

Replication And Growth In Cassava Cultivation And Uxorilocal Women’S Relations Among The Waiwai: A Mother's Reckoning With Death And Social Change, Laura H. Mentore

Tipití: Journal of the Society for the Anthropology of Lowland South America

Through an ethnographic examination of the shared capacities of cassava and womanhood for what I term growth and replication, I argue that Waiwai sociality seeks to curtail the trajectory of life towards finite death through the intervening act of cutting and replanting or replicating life in a vegetatively inspired form of the “episodic present” (Strathern 2021). An extended vignette demonstrates how these features of Waiwai sociality take shape in mother-daughter and sister relations at the core of uxorilocal residential living, and in a senior woman’s reckonings with illness, death, and social change.

Propagating Conviviality: Waiwai Cultural Transformation Of Moral Depravity, George F. Mentore

Tipití: Journal of the Society for the Anthropology of Lowland South America

This essay considers the problematics of anthropological translations when its responsibility to the codes of its modernist subjectivity persuades us to defer judgment on interpretations made of indigenous semiotics of life. It begins with this full disclosure before attempting to describe, from a translation of a Waiwai myth, how one can produce a guilty reading about their privileging of concern for conviviality. The Waiwai bodily feeling of well-being must be in place before relations of trust can be enacted. Transforming the vial aggressive feelings of strangers becomes a priority for hosting them. Maintaining feelings of conviviality within the community is …

Development And Validity Of The ‘Modified Mediterranean Prime Screen’ To Assess Dietary Intake Among Women Of Reproductive Age In Lebanon, Mariam Assaad, Sara Ajjour, Maya Rahme, Laila Al-Shaar, Hala Ghattas Ph.D., Ghada El-Hajj Fuleihan, Jana Jabbour

“The Hero Of My Own Life”: The Purpose Of The Fictional Self In The Life Writings Of Mary Wollstonecraft And Charles Dickens, Jessica M. Day

Honors Projects

This paper looks at Letters written in Sweden, Norway, and Denmark by Mary Wollstonecraft and David Copperfield by Charles Dickens as significant texts that combine fiction and life writing. Looking at fictional and autobiographical elements within each text, this paper argues that these authors manipulate genre to make significant claims about feminism and child activism. They participate in self-crafting—taking the self, something that is personal, and making it public and political. This paper argues that fiction allows the life writer to expand past the limitations of a single lifetime and speak to truths larger than the self. Letters written …

Downfall To Friendliness?: Analyzing Common Tropes In The Boy Who Loved Too Much, Heather Paglia

The Criterion

One of the most commonly held misconceptions regarding the disabled population is that living with any disability automatically decreases the quality of life. It is assumed that any deviation from society’s established norm for the perfect brain and body must be a burden. Both the physical and social implications associated with disability have forged in the minds of many the idea that a disabled life could not possibly be a good life. This overarching negativity, however, is turned on its head when considering Williams Syndrome, a rare genetic disorder more accurately described as happy syndrome. This so-called disability is not …

Moving “Passed” Life For Death, Gwyneth Morrissey

The Criterion

The paper Moving “Passed” Life for Death explores Emily Dickinson's poem #479, "Because I could not stop for Death," focusing on the theme of movement expressed through the word "passed." It analyzes the contradictory qualities of movement and stopping and how they interplay. At the same time, it looks into how the poem's periodic stopping points highlight the natural cycle of life and death, challenging the conventional and fearful understanding of dying. Dickinson's use of "passed" ultimately alludes to the persistence of life after death, altering readers' perceptions of mortality. The essay presents an intriguing interpretation of life, death, and …

Targeted Drug Delivery: Investigating Protein Corona Behavior, Atharva Markale

Theses

Due to high specificity and less toxicity, nanoparticles have become promising for targeted drug delivery against cancer, although they face challenges when they enter the bloodstream, making their behavior unpredictable. The deposition of proteins on nanoparticles, the protein corona, changes their biosignature, affecting their circulation, drug release potency, targeting ability, and immunogenicity. The continuous exchange of protein layers on a nanoscale is complex to analyze.

Nanoparticle tracking analysis (NTA) is a method to characterize nanoparticles in blood plasma by combining principles of light scattering microscopy and Brownian motion. In this work, time-dependent experiments with plasma were conducted to analyze the …

Electrochemical Nitrate Reduction To Ammonia On Cu Based Nanoparticles Using Quantum Mechanical Simulations, Kathan Bhavin Shukla

Theses

Nitrate reduction to ammonia (NRA) is critical for environmental remediation and energy conservation, as it can remove harmful nitrate (NO₃^-) from water sources while producing usable ammonia (NH₃). Cu represents one of the most promising non-noble-metal NRA electrocatalysts. However, the intrinsic catalytic activity of Cu facets and their influence under different pH conditions remain unclear, particularly in the presence of ions commonly found in wastewater such as Cl^-, Na⁺, Mg²⁺, and Ca²⁺. Using density functional theory (DFT) calculations, we evaluated the nitrate reduction to ammonia (NRA) pathways …

Strawberry Nectar Preservation Through Innovative Techniques And Energy Evaluation For High-Pressure Processing, Caterina Scaioli

Theses

Strawberries are universally adored by people of all ages, owing to their richness in vitamins, nutrients, and antioxidants, offering myriad health benefits, including combating free radicals. However, despite their popularity, strawberry juices or nectars are not commonly found in markets due to their delicate structure, which makes them prone to rapid deterioration of their prized qualities and vibrant red color. In the food industry, preventing browning and nutrient deterioration are often the primary challenges faced when processing red juices. Traditional preservation methods, such as pasteurization, are inadequate in maintaining their freshness. The focus of this study is to explore alternative …

Machine Learning Based Analysis Of Civil Infrastructure In The Presence Of Sparse Data, Megan Butcher

Doctoral Dissertations and Master's Theses

The high computational cost of estimating engineering demand parameters (EDPs) via finite element (FE) models, which incorporate uncertainties in earthquake events and material properties, limits the application of the Performance-Based Earthquake Engineering (PBEE) framework. Previous efforts to replace FE models with surrogate models have typically focused only on building parameters, necessitating re-training for new, unseen earthquakes. This paper introduces a machine learning-based surrogate model framework that addresses both earthquake and material parameter uncertainties to predict responses for unseen seismic events. Earthquakes are characterized by their projections on an orthonormal basis, computed using Singular Value Decomposition (SVD) of a representative ground …
