A Patient-Centered Approach To Physician-Assisted Death For Patients With Treatment-Resistant Major Depressive Disorder, Moc Lan Nguyen

Honors Program Theses

In medical ethics, the arguments for allowing physician-assisted death (PAD) access for physically and terminally ill patients are well-accepted. These arguments mainly stem from the rise of support for patient autonomy and recent criticisms of paternalism. While this notion in support of PAD is generally held in various medical disciplines, psychiatry remains staunchly couched in their conviction of paternalism. Compounded with the principle of suicide prevention, psychiatry is reluctant to accept PAD for its mentally ill patients as it goes against their profession’s role responsibilities. Furthermore, there is plenty of skepticism regarding mentally ill patients’ competency, which calls into question …

Indirect Effects Of Coral Bleaching On Tursiops Truncatus Diet And Foraging Behavior In Bocas Del Toro, Panama, Annabel Fiero

Scripps Senior Theses

Indirect effects, where another species or factor mediates the effects of a given species, are critical to ecosystem structure and resilience. Shifts in fish community structure, as a result of rapidly declining coral reefs in the Caribbean due to warming-induced bleaching, pose a threat to apex predators like Tursiops truncatus (bottlenose dolphins). Branching corals create habitat niches for numerous fish species. These fish rely on coral for food and habitat, and in turn provide food for upper trophic levels. Prior research has highlighted how coral bleaching will disrupt Acroporid reef building corals and fish community structure, but the effects of …

Making Faces, Elinor Attisani

Scripps Senior Theses

Making Faces critiques the naturalization of gender norms and asserts that all gender expression is learned and imitative. With respect to my work, “naturalization” refers to the attribution of patterns of behavior to an unbreakable essence at the core of a person; the distinct qualities that place masculinity and femininity in opposition are often attributed to natural characteristics of the male and female sexes. Judith Butler famously contradicts this myth of gender expression as the externalization of an underlying core identity in their book, Gender Trouble, where they argue that the repeated imitation of a nonexistent ideal is constitutive of …

“No Soy Una Santa Pero Estoy Blessed”: El Álbum Lux, La Lingüística, Y Rosalía Como Una Santa Moderna, Abigail H. Gustafson

Scripps Senior Theses

Esta tesis analiza el álbum LUX (2025) de Rosalía como un proyecto artístico que fusiona la espiritualidad, la lingüística y la identidad femenina en un contexto contemporáneo y globalizado. A través de referencias a figuras religiosas femeninas como Anandamayi Ma, Santa Rosa de Lima y Rabia Basri, Rosalía reinterpreta el concepto tradicional de la santidad y propone una visión moderna de la feminidad. Este análisis se apoya en la teoría de la performatividad de género de Judith Butler, argumentando que la identidad femenina en LUX se construye de manera fluida, múltiple y no limitada por categorías culturales o religiosas rígidas. …

How Semiflightless Birds Adapt: A Survey From Barú, Costa Rica, Eli P. Laloudakis

Scripps Senior Theses

When we think of birds, we think of flight. Because of this, scientific research often focuses on how birds evolved flight and how their wings function during flight. However, not all birds can fly or fly well, as wings wax and wane on developmental, seasonal, and evolutionary time scales (Dial and Heers 2021). Consequently, rudimentary wings can be found in developing birds, secondarily flightless or semiflightless birds, birds that undergo simultaneous molts, and extinct theropods with “protowings” (structures that preceded fully functional wings). Secondarily flightless and semiflightless birds often evolve where there is no/low predation, abundant year-round food supply, and …

Lead Biosorption By Oceanobacillus Profundus Kbz 3-2: Strategies For Bioremediation Systems In Kabwe, Danielle S. Desmarteau

Scripps Senior Theses

Lead contamination remains a significant global public health concern, particularly in Kabwe, Zambia, the site of a former lead mining operation. Bioremediation, which utilizes biological materials and processes to remove environmental contaminants, represents a promising approach for addressing lead pollution. However, the development of effective bioremediation systems requires a detailed understanding of the mechanisms underlying metal removal and the feasibility of implementation in low-resource settings. Oceanobacillus profundus KBZ 3-2, a bacterium isolated from Kabwe mine waste, has demonstrated the ability to remove lead from aqueous environments. This study proposes to investigate the mechanism of lead biosorption by this organism, …

Food Stamp Participation And Health Outcomes In Ca Immigrants, Esther Kang

Scripps Senior Theses

The U.S. social welfare system includes programs aiming to increase access to nutritious food to reduce nutrition insecurity. However, studies suggest that immigrants continue to face disproportionate risks of nutrition insecurity and may face barriers to enrollment due to legal status. This study, using secondary data from the 2023 California Health Interview Survey, examines the associations between food stamp participation, food insecurity, and clinical diagnosis of diabetes among adult U.S.-born, naturalized, and non-citizen adults in California. The findings suggest that those enrolled in food stamps are more likely to report food insecurity than those who are not enrolled, and that …

By working at an extremely small scale, nanotechnology allows for more precise and targeted treatment, reducing damage …

Public Libraries: Communities Need Them To Survive, Genesis Wilson

Integrated Studies

Public libraries continue to play a highly impactful and transformative role in community life, even as digital technologies reshape how individuals access information, participate in civic life, and access social support. The literature consistently shows that public libraries function not only as information centers but also as inclusive community anchors that advance digital equity, civic engagement, lifelong learning, and social well-being. Drawing on research from respected scholars such as Akst, Alemanne et al., Lewis, Elmborg, and Schencker, this literature review integrates key themes related to public libraries as community builders, technology and broadband leaders, and essential social support systems for …

Forage Legume Community Dynamics In Response To Stand Management, Nicholas Warren

Doctoral Dissertations

A primary challenge for perennial forage production systems is maintaining crop productivity and forage quality over time. Including legume species in these systems is an opportunity to reduce external inputs, to extend the seasonal productivity of a pasture, and to balance the nutritional characteristics of grass species. However, legume persistence in mixed stands is frequently poor. Identifying harvest practices, legume species, or species mixtures that improve legume persistence would help to maximize the ecosystem services of forages. I conducted a four-year field experiment (2019 to 2022) in southeastern New Hampshire to evaluate the productivity and persistence of four perennial legumes …

Perception Of Posed And Naturally Occurring Emotion Expressions In Close Friendships, Kaitlyn M. Mcmullen

Doctoral Dissertations

While relationships are critical to our daily emotional lives, the limited research on emotion perception among close friends presents inconsistent evidence concerning whether differences exist between close friends and strangers. The present work examined the ways in which familiarity between close friends’ shapes emotion perception. In Study 1a, expressors provided both naturally occurring and dynamic posed emotion expressions for seven emotion categories (anger, sadness, fear, disgust, happiness, surprise, and neutral) in order to develop a stimulus set where the stereotypicality of the expressions varies within-subjects. In Study 1b, a self-identified close friend of each expressor viewed and rated the expressions …

The Garden Of The Machine: Simulated Wildness And Digital Domestication In American Literature 1970-2020, Cameron Netland

Doctoral Dissertations

Studying American literature produced during the Information Age, from 1970 to 2020, reveals an evolution of wild human resistance to the increasing powers of digital technology. These increasing powers include capturing attention, fostering dependence, and training behavior through a process I call digital domestication. Digital domestication distances people from wildness, and as William Cronon writes in “The Trouble with Wilderness”, “Learning to honor the wild—learning to remember and acknowledge the autonomy of the other—means striving for critical self-consciousness in all of our actions.” (20). Through this framework of wildness, one reads characters in fictional narratives resisting non-coercive new technologies as …

Launching Love Online: How Soft-, Hard-, And No-Launch Practices Shape Perceptions Of Commitment And Relationship Security, Aleana Goetz

Master’s Theses

Social media has introduced new ways couples signal relationship status, ranging from a “hard launch” (a clear couple post) to a “soft launch” (subtle cues such as hands or hints) to a “no launch” (no posting at all). Although these posting choices may seem minor, they may shape how committed and secure a relationship feels. Guided by the Investment Model (Rusbult, 1980) and interdependence theory (Kelley & Thibaut, 1978), the present study examines whether relationship visibility on Instagram relates to perceived partner commitment and relationship security.

A total of 176 participants (36 male, 118 female, 22 did not report) viewed …

Mitochondrial Efficiency: Bridging Early-Life Environment And Organismal Performance, Kayla E. Lichtner

Master’s Theses

Mitochondria operate at the forefront of organismal-environmental interactions. Despite remarkable diversity in mitochondrial function both within and among species, all mitochondria serve a universal role in facilitating the flow of energy between organisms and their environment. Energetic efficiency, the way in which organisms assimilate and transform environmental substrate into physiological currency, is a major determinant of organismal performance. Although previous studies have shown that early-life environment can have lasting effects on metabolism, the underlying mechanisms driving the emergence of mitochondrial phenotypic variation remain poorly understood. Leach’s storm-petrels (Hydrobates leucorhous) provide a valuable opportunity to investigate longitudinal hypotheses of …

Think Jurassic Park. This honors thesis presents a comprehensive review of the history, current state, and methods of the field of molecular paleontology. Drawing on peer-reviewed literature and scholarly resources accessed through databases such as EBSCO and Bierce library, this review examines key techniques such as Next Generation Sequencing and amino acid racemization and will go over limitations and controversies in the field. It will also explore potential new …

Rebuilt From The Same Stone: Religion And Colonization In Sixteenth-Century Mexico, Aziren South

Williams Honors College, Honors Research Projects

When the Spanish landed in what is now Mexico in the early sixteenth-century, religious figures on mission trips took it upon themselves to convert indigenous peoples to Christianity and to the European way of life. The role of these missionaries was complex. They wanted to abolish the way of life of the societies they encountered, but they were also some of the most prominent defenders of the people they were trying to convert. They lived with them, learned their languages, advocated for their protection, and some supported indigenous efforts to preserve their history in writing. Ultimately, this paper aims to …

Rate Response Of Curlyleaf Pondweed And Native Plants To Flumioxazin In Minnesota Lakes, Pearl J. Jensen

All Graduate Theses, Dissertations, and Other Capstone Projects

Curlyleaf pondweed (Potamogeton crispus L.) is an invasive aquatic plant present across the United States that causes significant recreational issues, outcompetes native plant species, and depletes water quality. Before senescing in mid-summer, curlyleaf pondweed forms a large number of turions that can lay dormant in the sediment for several years. Typical herbicide management of this species occurs in early spring to target the plant before turion production occurs and while native plants are dormant. Flumioxazin has shown potential in curlyleaf pondweed management in small scale studies, but its effects have not been assessed in operational management. In this study, treatments …

Ethanol And Iron Absorption Interactions Within Crayfish Invertebrate Models, James Rollman, Andrew Wissmar

Williams Honors College, Honors Research Projects

Analysis of the effects of alcohol consumption (ethyl-alcohol) on iron absorption within crayfish model. The use of tube-feeding provides a novel, more precise output, and less invasive procedure compared to the traditional approach of dissolving the target substance in tank water and measuring hemolymph changes. The project aims to determine the extent to which alcohol influences iron absorption. Ultimately, the choice of iron reflect the future potential to aid in research with genetic hemochromatosis and or Iron overload.

Ceramics And Trade In Mesoamerica: Identity And Resistance In The Maya Culture, Mason A. Swanson

Williams Honors College, Honors Research Projects

The region of Mesoamerica has been researched extensively by archaeologists over the past decades. There are numerous cultures and civilizations that occupied Mesoamerica over thousands of years. This paper will focus on the Maya, one of the most researched and examined of the cultures of Mesoamerica. By examining the ceramics and trade of the Maya one can reconstruct how the Maya identity was viewed in the past. Often the Maya are suggested to have experienced a collapse at the end of the Classic period around (AD 900). This, however, is an oversimplification of the events that occurred. The goal of …

The Implementation Of A Token Economy On The Behaviors Of Children With Adhd, Dominic M. Hritsko

Williams Honors College, Honors Research Projects

The Saturday Treatment Program (SatTP) is a ten-day treatment program that was designed through the Cleveland Clinic and takes place at a middle school on Saturdays during the school year. The program design follows that of the Summer Treatment Program, where counselors utilize a comprehensive point system that is part of a token economy to evaluate children’s behaviors (ADHD summer treatment program). I will be working with other counselors led by Dr. Hallie Fetterman Ph.D., a pediatric psychologist, to deliver the program and evaluate the behaviors of sixteen children. The program is split into three age groups: six through …

The Effects Of Habitual Temperature And Diet On Crayfish Physiological Processes, Tyler D. Deramo, Sunny Rana, Victor Popoviciu

Williams Honors College, Honors Research Projects

We will use crayfish to test the individual and combined effects of temperature and diet to see how they impact physiological processes such as metabolism, growth rate, molting patterns, and behavioral analysis. A total of forty-eight crayfish will be used throughout the experiment, and they will be housed in separate containers. A plant-based diet (consisting of fresh kale) and an animal-based diet (consisting of dried bloodworms) will be tested alongside room temperature (~18 degrees Celsius) and a warmer habitual temperature (~24 degrees Celsius). Metabolism will be measured via O2 consumption, and growth will be measured by weighing and measuring the …

Toadally Not A Frog: A Neuromuscular Physiology Study, Iris Renna

Williams Honors College, Honors Research Projects

Upper-level physiology labs in undergraduate education use freshly isolated bullfrog and/or leopard frog tissue to teach core concepts in nerve and muscle physiology. Sourcing live animals for routine educational use raises ethical and conservation concerns. Cane toads (Rhinella marina) are an invasive species that are routinely culled, can provide a potential source of laboratory animals which would remove pressure to native amphibian populations. This study tested the hypothesis that cane toads can serve as a functional substitute for bullfrogs and/or leopard frogs in the muscle and nerve physiology lab. Isolated sciatic nerve and gastrocnemius muscle preparations from cane …

Methods Of Euthanasia In Laboratory Animals, Jaiden L. Corley

Williams Honors College, Honors Research Projects

The current honors research project will focus on the current use of carbon dioxide (CO2) as a means of euthanizing laboratory mice. CO2 is commonly used as a means of euthanizing laboratory animals and has been a standard of practice for mamy years. it is regarded as fast, painless, and efficient in overwhelming the respiratory control centers of the brainstem and resulting in respiratory depression and death. However, there continues to be debate and ongoing research regarding the 'humaneness' of this approach to euthanasia, and the American Veterinary Medicine Association (AVMA) suggests the inclusion of isoflurane (a volatile anesthetic) as …

The Right To Seek Joy, Tyler Rose Clemons

Faculty Publications

Within the past three years, roughly half of American states have restricted access to gender-affirming medical treatment for children. In this article, I argue that these bans violate transgender children’s right to liberty guaranteed by the Fourteenth Amendment’s Due Process Clause. I do so by excavating the Framers’ understanding of liberty as the right to seek joy. Rooted in the philosophies of John Locke and Epicurus, the Framers understood liberty as the right to make important life decisions according to one’s subjective preferences without undue interference from the government. Based on this understanding, I develop a new framework for substantive …

Presidential Slaves: The Story Of Black People In The Lives Of Antebellum U.S. Presidents, Nika Davis

History Dissertations

The historical narrative about American slavery included many topics such as the African slave trade, the Middle Passage, slave culture, rebellions, religion, and abolition.  This study revealed more information to be examined in the record of American slavery relating to the presidents of the United States and their enslaved laborers.  This oversight proved prevalent during the years leading to the American Civil War from 1820-1860.  Therefore, this dissertation focused upon the enslaved and free Black people who intersected with the presidents and their friends, political acquaintances, and family.  By studying their lives, this dissertation revealed that the slaves associated with …

Red Clover Isoflavones And Establishment In The Context Of Tall Fescue Toxicosis Mitigation In The Mid-South, Jonathan L. Stephens

Theses and Dissertations--Plant and Soil Sciences

Low levels of red clover (Trifolium pratense L.) have been shown to mitigate tall fescue (Lolium arundinaceum (Schreb.) toxicosis symptoms. This is because of the presence of plant-produced compounds known as isoflavones. Production of a red clover supplement on a commercial scale would require industrial-level processing of raw plant material into granules or pellets. The first study of this thesis evaluated the impact of drying temperature on bioavailability of isoflavones. Drying temperatures up to 104°C had minimal impact on isoflavone concentrations. Additionally, varietal differences in isoflavone concentrations were documented. The second study of this thesis evaluated optimal establishment …

Characterizing The Role Off The Sp1/Klf Transcription Factor Huckebein In The Drosophila Melanogaster Ventral Nerve Cord, Benjamin Almond

Distinguished Undergraduate Researcher Program

Over the course of embryonic development, the ectodermal cell layer gives rise to a vast array of neurons and glia patterned across the central nervous system (CNS). Neurulation and specification is achieved in the ectoderm through temporospatial patterns of transcription factor (TF) expression, many of which are conserved across evolutionary history. These conserved regulatory motifs allow the use of Drosophila melanogaster to study the mechanisms of neurodevelopment across the animal kingdom. The huckebein (hkb) gene encodes a conserved SP1/KLF TF known to play important roles in cell cycle regulation, tissue morphogenesis during tubular organ development, and gut specification in Drosophila. …

Examining The Pre-Columbian Use Of Psychotropic Plants In The South American Andes: Tobacco, Coca, And Ayahuasca, Jalayne Allison

Distinguished Undergraduate Researcher Program

This thesis offers a literature review that traces the origins and variations in the use of tobacco (Nicotiana sp.), coca (Erythroxylum coca spp.), and ayahuasca (Banisteriopsis caapi) in the Andean highlands and Amazon region along the western coast of South America. This mountainous region stretches across seven countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, and Argentina. Diverse South American Indigenous groups and ancient civilizations, such as the Inca Empire, have inhabited this area. This review delves into key concepts of Andean cosmology, especially those related to ecology and hydrology as interpreted through Inca beliefs. These concepts are pivotal in the application …

Physiological Leptin Replacement Does Not Reverse Metabolic Adaptations To Starvation In Sprague Dawley Rats, Sydney Junot, Layla Deprimo, Camille Meaux, Arline Narez, David Mcdougal

Distinguished Undergraduate Researcher Program

Historically, low insulin levels were the signaling event considered responsible for metabolic adaptations to starvation, such as increased sympathetic outflow and increased serum levels of ketones, glucagon, and free fatty acids. Leptin, a hormone produced by adipose tissue, is known to decrease in response to caloric restriction. Recent work in the field suggested that leptin infusion in the final hours of a 48-hour fast reversed all metabolic adaptations to starvation, thus raising questions about an underappreciated role of leptin in the starvation response. This study tested whether physiological leptin replacement, maintaining fed plasma leptin concentrations, during a 72-hour fast in …
