Partisan Cues, Emotion, And The Efficacy Of Corrections To Misinformation About Democratic Norms, Julia Ruth James

Honors Theses

Political misinformation and threats to democratic norms are major problems for American democracy. This thesis examines belief in misinformation about democratic norms and the efficacy of corrective information (fact-checking) in multiple circumstances, specifically analyzing the effects of emotions, partisan cues, and conspiracy thinking on the efficacy of the corrective information. To measure these effects, a survey of 45 questions was fielded through Lucid. Approximately 2000 respondents answered questions about their demographics, political beliefs/participation, and media habits. These respondents were subsequently randomly sorted into 1 of 8 experimental groups and received an emotional priming activity and a simulated news article containing …

Bert Argues: How Attention Informs Argument Mining, Ting Chen

Honors Theses

Argument mining is the automatic identification and extraction of structure from argumentative language. Previous works have constrained the argument structure to forming strictly trees in order to utilize efficient tree-specific techniques. However, arguments in the wild are unlikely to exhibit this constrained structure. Given the recent trend of fine-tuning large pre-trained models to reach state of the art performance on a variety of Natural Language Processing (NLP) tasks, we look to leverage the power of these deep contextualized word embeddings towards the task of non-tree argument mining. In this paper, we introduce a new pipeline which utilizes pre-trained BERT based …

Indolizine Donor-Based Dyes For Applications In Fluorescence Biological Imaging, William Meador

Honors Theses

NIR emissive fluorophores are intensely researched due to their potential to replace modern imaging procedures. Many molecular strategies have been employed in the literature to optimize fluorophores for deeper NIR absorption and emission, biocompatibility, and higher fluorescence quantum yields. Amongst the fluorophores studied to date, proaromatic indolizine donors are attractive alternatives to traditional alkyl amine and indoline based donors due to their 1) lower energy absorption and emission facilitated by proaromaticity, 2) large Stokes shifts due to increased dihedral angles about the π-system, 3) ease of functionalization and capacity for bioconjugation at the phenyl ring, and 4) potential for further …

Modeling Of Covid-19 Utilizing Various Compartmental Models To Predict Infection Rates Throughout Michigan, Colleen M. Staniszewski

Honors Theses

Compartmental modeling is a method of employing math to create a visual representation of a disease interacting with a select population, typically used in epidemiology analyses. This project applies compartmental modeling equations to data collected on the various aspects of COVID-19 in Michigan. Comparing current data to past predictive models, as well as the visual representations that were developed through the various compartmental modeling methods, allows an assessment of the effects of the preventative measures taken by the state, the various rates at which the infection is able to spread, as well as the potential path and spread of the …

Socrates And The Divine Mission Of Political Friendship, Ronahn I. Clarke

Honors Theses

Plato is widely regarded as an authoritarian political thinker on account of Socrates’ endorsement of rule by philosopher kings in the Republic. Yet the Republic should not be mistaken for a political treatise or the entirety of Socrates’ political theorizing. Each of the Socratic dialogues is concerned with the political endeavour of reorienting souls within communities of souls toward virtue via philosophical discussion. This project examines the Lysis, the Gorgias, the Symposium, the Republic, and other dialogues in the context of the philosophical mission Socrates establishes in the Apology. Socrates’ philosophical work expresses a …

The Transcendental Foundation Of Kant's Cosmopolitanism, Daniel J. Ellison

Honors Theses

Scholarship on Kant’s philosophy of history has insufficiently considered its place in the larger system of transcendental idealism. In this project, I argue that Kant’s guarantee of progress in history is grounded in his universal characterizations of human nature, which he makes both explicitly, as with the notion of “unsociable sociability” put forth in “Idea for a Universal History from a Cosmopolitan Perspective,” and implicitly, as with what I term a responsiveness to reasons. These characterizations are grounded, I claim, in an attribution of reason which is always already achieved to the constitution of human beings, which emerges out of …

Reconstructing The Voting Rights Act: Subnational Action And Voting Rights Post-1965, Sean M. Holly

Honors Theses

The discussion of suffrage and the development of the U.S. electorate is misguidedly based solely around federal action; constitutional amendments and federal legislation are commonly revered as primary determinants of the right to vote. This tendency poses a specific problem with contemporary discussions of the Voting Rights Act of 1965. Specifically, discussions of the VRA ignores the ability of subnational actors to innovate politically and readjust their vehicles of political development in the wake of federal supposition of state powers. The Voting Rights Act did not destroy state authority regarding the right to vote; it merely disrupted their vehicles of …

Mot-Based Lifetime Measurements Of Potassium-39 5p1/2 And 5p3/2 States, Huan Q. Bui

Honors Theses

This thesis presents measurements of the lifetimes of 5p1/2 and 5p3/2 of K39 via exciting a cloud of K39 atoms in a magneto-optical trap by a linearly-polarized pulse of 405 nm light followed polarization-specific, time-resolved fluorescence detection. We find that $\tau_{5p1/2} = $ 138.8 $\pm$ 1.6 ns, which is consistent with past measurements \cite{triumf}, \cite{berends} and calculations \cite{safranova}. The $\tau_{5p3/2}$ measurement is naturally more involved since quantum beats due to hyperfine and Zeeman effect are present. Our observation of $\tau_{5p3/2} =$ 137.6 $\pm$ 3.1 ns and $\tau_{5p3/2} =$ 136.0 $\pm$ 2.4 ns, obtained from two slightly different approaches, are compared …

Estimating Heading From Optic Flow With Neural Networks, Natalie T. Maus

Honors Theses

Humans have a remarkable ability to estimate their direction of self-motion, or heading, based on visual input stimulus (optic flow). Machines, on the other hand, have a difficult time with this task, especially when flow is introduced that is inconsistent with the motion of the observer. For example, when moving objects enter the field of view, their motion provides inconsistent flow data which often disrupts heading estimates of current heading estimation models. We investigate the ability of neural networks to estimate heading from optic flow data and the limitations of these models when different variations of inconsistent flow are introduced. …

The Quantitative Assessment Of Pond Scum: An Examination Of The Biogeochemistry Of Phosphorus Cycling In The Belgrade Lakes, Abbey M. Sykes

Honors Theses

The internal recycling phosphorus in freshwater lake bottom sediments represents a significant source of hypolimnetic phosphorus (P) release for many of Maine’s lakes. In summer months, Maine lakes often thermally stratify and the lake hypolimnion develops anoxia, leading to a reduction in redox potential at the sediment-water interface. These reducing conditions facilitate the reductive dissolution of ferric iron, and, since phosphorus is often present in freshwater lake sediments as solid FeOOH-PO₄ complexes, results in release of soluble phosphorus into the water column. Our current study presents field and laboratory data from sediment fractionation extractions designed to quantify concentrations of …

Covid And The Classroom: The Impact Of The Covid-19 Pandemic On Special Education And Policy Implementation, Danielle Lange

Honors Theses

This research examines how the COVID-19 pandemic impacted the learning of special education students and the implementation of the Individuals with Disabilities Education Act (IDEA) in the United States. The importance of this research is reflected in the unprecedented and novel context of the COVID-19 pandemic. Never at any point in IDEA history have all special education students been simultaneously denied the services that are considered essential for their development and advancement. While some previous research has looked into how constraints such as natural disasters have impacted students, never has anything this drastic been studied. In this study, I found …

Convolutional Audio Source Separation Applied To Drum Signal Separation, Marius Orehovschi

Honors Theses

This study examined the task of drum signal separation from full music mixes via both classical methods (Independent Component Analysis) and a combination of Time-Frequency Binary Masking and Convolutional Neural Networks. The results indicate that classical methods relying on predefined computations do not achieve any meaningful results, while convolutional neural networks can achieve imperfect but musically useful results. Furthermore, neural network performance can be improved by data augmentation via transposition – a technique that can only be applied in the context of drum signal separation.

Impact Of The North American Monsoon On Molt Migrant Passerines, Liuqingqing Yang

Honors Theses

Breeding, molt, and migration place considerable yearly demands on migrating passerines in North America. Due to conflicts in energy allocation, many species have evolved migration strategies that prevent temporal overlap in these processes. However, there is recent evidence that some passerines which breed in western North America migrate to intermediate stopover sites to carry out molt, conflating molt and migration. Factors influencing the evolution of such a strategy are believed to include both aridity on breeding grounds and dependable flushes of late-summer productivity in the southwestern United States and northwestern Mexico. This productivity occurs due to the brisk rainfall of …

Counting Conjugacy Classes Of Elements Of Finite Order In Compact Exceptional Groups, Qidong He

Honors Theses

Given a compact exceptional group $G$ and $m,s\in\mathbb{N}$, let $N(G,m)$ be the number of conjugacy classes of elements of order $m$ in $G$, and $N(G,m,s)$ the number of such classes whose elements have $s$ distinct eigenvalues. In string theory, the problem of enumerating certain classes of vacua in the string landscape can be rephrased in terms of the study of these quantities. We develop unified combinatorial algorithms based on Burnside's Lemma that can be used to compute both quantities for each of the five compact exceptional groups. Thus, we provide a combinatorial, alternative method to that of Djoković and extend …

The Museum As A Mirror: Reinterpreting And Delinking American Landscape Art From Colonial Narratives, Blythe C. Romano

Honors Theses

Art museums have recently been looking at their existing collections with heightened scrutiny, revisiting their decision to display colonial works uncritically in their gallery spaces, and reconsidering the idea that there is such a thing as a unified art historical canon. These conversations regarding reinterpretation are necessary for all museums that choose to display art with problematic histories, as this information is owed to visitors -- especially within the settler colonial context. The Colby College Museum of Art in Waterville, Maine is one site where such collection and gallery “reinterpretation” has begun to be implemented and discussed. For example, in …

Microbiome Community And Parasitic Infections In Wild Bees, Mark G. Young

Honors Theses

The microbiome is increasingly recognized for its complex relationship with host fitness. Akin to primates and other social animals, bumblebees harbor a specific microbiome derived from social contact. The bumblebee microbiome is characteristically species poor, with just a few “core” phylotypes accounting for the majority of total abundance. Genomic analyses reveal phylogenetic congruence and adaptation of the core endosymbionts to the bumblebee gut, indicating a shared evolutionary history. Prior investigations reveal that the relative abundance of core microbes is negatively associated with infection by a trypanosome, Crithidia bombi, and that the microbiome has a mechanistic role in immunity. As …

Us And Them: Populism In The United States, Julia E. Pfau

Honors Theses

The term “populism” has been thrown around recently—heedless of any cohesive meaning—to describe a wide variety of politics. But can we define populism with sufficient clarity and precision as to make it a useful term with which to analyze political rhetoric? This thesis weaves together the fragmented literature on populism to invent a unique definition: populism in the United States is a mode of political persuasion characterized by an effort to promote the interests of “the people,” understood to be a monolithic and moral group of ordinary Americans, against a “corrupt” elite or establishment which obstructs these interests. Using this …

"Nice, Quiet Hand": The Creation And Navigation Of Feeling Rules In A Second Grade Classroom, Avery Munns

Honors Theses

Emotions are largely viewed as individual and internal, but in reality, emotions are socially situated. This project aims to use a sociology of emotions framework in order to explore how emotional expectations are created, maintained, and navigated within a classroom environment. Through a series of observations over the course of a month, I set out to answer questions surrounding which emotions were encouraged, which emotions were discouraged, and how both teachers and students created and navigated these feeling rules. Overall, I found that emotions were largely discouraged, especially through the overarching feeling rules of “be quiet” and “control your body.” …

Sailors’ Perceptions Of Offshore Wind Energy In The Northeastern United States, Henry Harris

Honors Theses

Offshore wind is an expanding form of renewable energy in the United States that will continue to grow through state and federal mandates. Offshore wind has often been met with criticism from a variety of ocean user groups and the academic literature has attempted to include the opinions of all user groups in order to improve policy making decisions. One of the biggest ocean user groups has been left out of the research, sailors. We investigated sailors’ perceptions of offshore wind in the Northeastern United States through a quantitative survey and qualitative interviews to provide context, hoping to answer the …

Investigating The Agn-Merger Connection Using Close Galaxy Pairs In The Candels Fields, Sean L. Dougherty

Honors Theses

Galaxy mergers are catastrophic events in that they greatly change the properties of the galaxies involved. Observations of the nearby universe suggest that they may also be able to trigger active galactic nuclei (AGN) even prior to the final coalescence, though there is much controversy surrounding this belief, particularly at high redshifts. In order to address this question, we have assembled a large sample of photometric galaxy pairs within the GDS and EGS fields of the CANDELS survey. We use photometric redshift probability distribution functions and the combined redshift probability function to assign probabilities for each projected pair. We incorporate …

Covid-19 Media Exposure And Parenting, Abagail Roy

Honors Theses

Rationale- The COVID-19 pandemic has led to a drastic change in the way of living for most parents. A study conducted during the lockdown of Italy found that parents experienced a high level of distress (Marchetti et al., 2020). Several studies have been conducted to find how media exposure and screen time affect children but much less research has been conducted on how media exposure is related to parental feelings and parenting.

Methods- The aim of this paper is to explore the role of COVID-19 media exposure in parental aggravation, closeness to children, parental self-regulation, intolerance of uncertainty, and resourcefulness. …

Improving Psychological Pre-Surgical Evaluations For Chronic Back Pain By Linking Data Of Pre-Surgicalmmpi-2-Rf And Post Surgical Pain Interference On Emotional And Physical Functioning, Ethan Hayes

Honors Theses

Chronic pain is running rampant, and its treatment options can sometimes be more dangerous than the pain itself. With such a widespread prevalence – and chronic in the name - numerous individuals are left to deal with daily anguish that fails to abate. This Honors Thesis examines a sample of patients presenting with chronic pain and attempts to validate previous research investigating what factors determine candidacy for a possible treatment, dorsal column spinal stimulator surgery. Research supports that this treatment may have beneficial effects, but patients are sometimes unable to gain respite, despite having a stimulator implanted into their lower …

Relationship Between Narcissism, The Economy, And The Pandemic, Ruby A. Staten

Honors Theses

Narcissists are more likely to be found in individualistic cultures. The study focuses on the economic decline associated from the pandemic and the reduced narcissism levels in the population. Narcissism levels from the University of South Alabama undergraduate students would be lower in Fall 2020 compared to Fall 2019. This was assessed using students enrolled in introductory psychology courses during either Fall 2019 or Fall 2020 semesters who completed the Narcissistic Personality Inventory during a subject pool registration process. Predictions were made that the NPI scores would be lower for the Fall 2020 sample compared to the Fall 2019 sample.

Gq-Mediated Ca** Signals In Human Airway Smooth Muscle Cells, Hanna Viktoria Bobinger

Honors Theses

Current asthma therapies include corticosteroids, long acting β2-adrenergic receptor (β2-AR) agonists paired with corticosteroids, or short-acting β2-AR agonists used in rescue inhalers. Chronic use of β-agonists results in diminished effectiveness, and use of long-acting β-agonists can even exacerbate asthma symptoms; this is partly because anti-inflammatory therapy does not directly address the exaggerated airway narrowing due to excessive shortening of airway smooth muscle (ASM), which is the hallmark of asthma. These observations led our collaborators to investigate other potential asthma therapies – bitter taste agonists. 2 Bitter taste agonists, such as chloroquine, activate a subset of Gq-coupled receptors known as bitter …

A Foray Into The Interval Timing Capabilities Of Tufted Capuchin Monkeys (Cebus [Sapajus] Apella), Gryff Griffin

Honors Theses

Time is a critical part of life and timing on the range from milliseconds to minutes has proven to be critical for several behaviors such as foraging and movement. While the exact neurological structures of interval timing are currently undefined, several studies have been completed comparing the interval timing capabilities of humans and nonhuman primates. However, these studies have unanimously utilized members of Macaca, which limits the abilities for researchers to make apt comparisons between humans and all nonhuman primates. This study sought to investigate whether tufted capuchins (Cebus [Sapajus] apella) have the capability to measure time …

The Role Of Inflammasome In Vascular Remodeling Following Injury, Ted Amadi

Honors Theses

The purpose of the project presented in this thesis is to assess the contribution of inflammasome activation in mediating vascular wall remodeling that occurs following carotid artery injury due to decreased blood flow. To examine this, we used a mouse model of carotid artery ligation in mice lacking the expression of a key mediator of the inflammasome signaling pathway. Following ligation, we completed a histological assessment to compare the degree of the neointima formation and expression of inflammasome related proteins in both injured and the non-injured contralateral carotid artery in both wild-type (WT) and Caspase 1 knockout mice (Cas1 -/-).

Determination Of Pollutant Load Reductions To Three Mile Creek As A Result Of The Implementation Of Storm Water Bio-Infiltration Basins On The Usa Campus, Jordan E. Blackmon

Honors Theses

Three Mile Creek has been identified as an impaired urban stream and is now a priority for cleanup for both the City of Mobile and the Alabama Department of Environmental Management. Methods to better manage storm water runoff on the USA campus have begun, with a goal to reduce sediment and nutrient inputs to Three Mile Creek. Both sediment and nutrient inputs to Three Mile Creek disrupt habitat and lower dissolved oxygen concentrations, which are detrimental to overall stream health. Low Impact Development strategies are an innovative way to use nature-like, green-infrastructures to minimize storm water runoff quantity and improve …

Caregiver Knowledge, Perceived Self-Efficacy, And Level Of Confidence In Limiting Bedtime Screen Use In Preschoolers, Emily Hollingsworth

Honors Theses

Screen time usage is a major factor leading to negative behavioral and health consequences in young children. Screen time also affects sleep, with prior research showing a significant association between screen time, particularly at bedtime, and reduced sleep duration and increased sleep problems. The initial aim of this research was to measure and attempt to increase, through an educational intervention, the knowledge, perceived self-efficacy, and confidence of study participants/primary caregivers with regard to limiting the bedtime screen use of their preschoolers with the goal of health promotion. It was intended to be a quantitative, quasi-experimental, multi-site, pre- post-intervention case study. …

Comparison Of Resilience, Empathy, Anxiety, And Depression Levels In College Aged Individuals Who Have A Sibling With A Developmental Disorder And Those Who Have A Typically Developing Sibling, Cecelia Prentiss

Honors Theses

Observing and analyzing the relationships between siblings can bring insight to what kinds of behaviors they will be inclined to have, as well has how prominent those behaviors will be. Specifically, it is important to analyze and compare levels of resilience, empathy, anxiety, and depression in individuals who have a sibling with a developmental disorder (DD) and those who have a typically developing (TD) sibling. This research looks to find out more information on college-aged individuals who have a sibling with a developmental disorder. There have been many studies that have conducted research to show how children and older adults …

Characterization Of Bpa Sensitive Strains In C. Elegans, Giulianna I. Escobar

Honors Theses

Bisphenol A (BPA) has been present in our environment since 1891 when it was first synthesized by Aleksandr Dianin. BPA has since been a topic of interest due to the possibility of diseases associated in human consumption of the chemical. Interestingly, Caenorhabditiselegans, commonly known as C.eleganshave shown to be able to tolerate the chemical. Thisorganism is an advantageous model organism for research since they are simple organisms to study, cheap, produce a large brood size, and have a short life cycle. Previously a forward genetic screen was done to isolate 2000 healthy strains in order to determine which strains showed …
