Dignity And The Free Press, Erin C. Carroll

Georgetown Law Faculty Publications and Other Works

As American institutions wither and die, those who believe in their importance must reflect and rebuild. One institution worthy of sustained attention is the free press. Divorced from government by design, the press can benefit from efforts to reinvigorate and reinvent it in ways that institutions more directly under the federal government’s thumb cannot. To best undertake these efforts, we need a richer understanding of why a free press is vital. Articulating the values that underlie the need for this institution is necessary not only to build the most robust free press, but also to best exercise our freedoms as …

Oral Losartan Yields Subtherapeutic Airway Exposure Compared To Nebulized Delivery And Fails To Improve Mucociliary Clearance In Cystic Fibrosis., Charles D. Bengtson, Andreas Schmid, Michael D. Kim, John S. Dennis, J Steven Leeder, Kirby L. Zeman, William D. Bennett, Juan Sabater, Nathalie Baumlin, Matthias Salathe

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Transforming growth factor-β1 (TGF-β1) contributes to more severe pulmonary disease in people with cystic fibrosis (pwCF). Our preclinical in vitro and in vivo studies demonstrated that losartan could reverse TGF-β1-mediated mucociliary dysfunction, albeit at doses difficult to achieve by oral administration. This study therefore examined airway losartan concentrations after oral and inhaled dosing to evaluate if oral losartan could be even expected to improve mucociliary clearance.

METHODS: We conducted comparative pharmacokinetics studies in sheep assessing airway surface liquid (ASL) concentrations of losartan and its metabolites, EXP3179 and EXP3174, after oral and inhaled administration. Another pharmacokinetic study used oral losartan …

Porous Hydrophobic Adsorbent Coatings For Carbon Dioxide Capture, Samuel Babatunde Olushola

Theses and Dissertations

This work presents the development of a porous, hydrophobic zeolite 13X coating for the separation of carbon dioxide (CO₂) from flue gas or natural gas. Zeolite 13X was combined with yeast, glucose, and sodium alginate as pore-forming agents, and with polytetrafluoroethylene (PTFE) and Polydimethylsiloxane (PDMS) as hydrophobicity-inducing agents to enhance water resistance while maintaining CO₂ access to the adsorbent. The study explored PTFE/13X mass ratios ranging from 0 to 2.33 to investigate the interplay between hydrophobicity and CO₂ uptake. The wettability of the coating was characterized by using a temporal water contact angle (WCA) measurement. Increasing …

The Effects Of Self-Management On Portion Control Consumption In A Natural Setting, Amber Nicole Lampert

Theses and Dissertations

Obesity is a significant public health concern, with overeating as a primary contributor. Despite national nutrition initiatives, most Americans consume inadequate amounts of fruits and vegetables while exceeding recommended portions of calorie-dense foods. Understanding food groups and recommended portion sizes of each may be a prerequisite skill for a health initiative aimed at weight loss. Given that environmental and behavioral factors influence eating behaviors, Applied Behavior Analysis (ABA) offers an evidence-based framework for improving nutritional habits through self-management interventions. This study examined the effects of self-management components on portion control within a natural eating environment. Four adult participants, one male …

Optimisation Of Photosensitive Recording Materials For Broadband Holographic Optical Elements, Michael Murray

Doctoral

The introduction of broadband (white) LED outdoor lighting has led to significant energy savings. However, this has come at the cost of increased light pollution which has negative impacts both on ecological systems and human health. This light pollution is largely the result of the lack of control measures for the directionality of the light emitted by outdoor LED lighting. The lack of directionality also results in higher energy consumption in order to compensate for the light scattered to the atmosphere and sufficiently illuminate the target area. In this thesis holographic optical elements (HOEs) are proposed as a complementary technology …

Mere Machines: Why Originalism Requires Robotic Judging, Michael Showalter

SMU Law Review Forum

In 1776, Thomas Jefferson argued that judges are “mere machines.” This statement captures founding generation’s conception of the judicial task. From Edward Coke to Montesquieu to William Blackstone to Alexander Hamilton to John Marshall, the founding era’s governing legal tradition taught that judges do no more than mechanically apply the law to reach a case’s correct answer. Judges find the law, the Founders consistently emphasized, they do not choose it.

Under originalism, that original understanding of the Article III judicial power controls how federal judges must adjudicate today. Theorists leveled sustained criticism against the Framers’ beliefs in the twentieth century, …

Historic Patterns Of Growth And Destruction In Nj Seagrass Meadows, Masen Eck

Theses, Dissertations and Culminating Projects

Seagrass meadows are one of the many habitats worldwide under threat from human disturbance and worsening climate conditions. This habitat provides many critical ecosystem services to coastal environments, which is why conserving and restoring seagrass meadows is critical. This study investigates the long-term success and failures from several eelgrass restoration sites in Barnegat Bay, New Jersey. Aerial imagery from multiple years were digitized in ArcGIS to assess restoration trajectories over time. Three of the sites were assessed over a period of twelve years (2012-2023), and one site was assessed twice (2021 and 2023). Results from these time series analyses showed …

"Some Women Make It Look So Easy": An Analysis Of Jenny Offill's Fragmentary Novels And Their Critique Of Postfeminist Sensibility, Kimberly Crooks

Theses, Dissertations and Culminating Projects

Jenny Offill’s novels Dept. of Speculation and Weather are each narrated by a woman who exists in a postfeminist era that insists upon the achievability of a happy work-life balance. Despite the lofty career aspirations now afforded to women, the protagonists find themselves burdened by the gendered responsibilities that disproportionately hold them responsible for domestic duties, childcare, and emotional labor. Both protagonists use a fragmented narrative style to convey their consciousness, and the texts are composed of hundreds of short fragments that include memories, self-reflections, philosophical musings, lines of poetry, fun facts, questions, and more. While the narratives do not …

Shape Variation In The Mandible Of The Borophagine Canids And Implications For Predatory Behavior, Benjamin Neavear

Theses, Dissertations and Culminating Projects

The borophagines are an extinct lineage of canids that inhabited North America for more than 20 million years. This group included genera such as Aelurodon, Borophagus, and Epicyon. Borophagines are commonly referred to as “bone-crushing dogs” because their skull morphology converged with that of extant hyenas, predators capable of consuming bone. The purpose of this study was to determine whether convergence was present in the mandible, an anatomical structure strongly correlated with feeding behavior, particularly in the genera Aelurodon and Borophagus. It was hypothesized that most borophagine taxa possessed mandibular shapes similar to those of hyenas. Numerous mandibular characters were …

Theses, Dissertations and Culminating Projects

Sustainable food systems require not only technological innovation but a more profound understanding of the professionals involved in the field. Even though the topic of sustainability is currently gaining importance throughout the food industry, the real expertise of food scientists is under-researched. PURPOSE: The purpose of this study is to explore food scientists' perspectives on sustainability, how these perceptions influence the way they pursue their careers, and how they view their impact in the larger sustainability agenda of the food industry. METHODS AND MATERIALS: This study captured detailed insights of 22 food scientists’ perspectives through qualitative methods. Food scientists in …

Creating A "Good Person": Netiquette And Instagram, Melissa S. Danai-Nolder

Theses, Dissertations and Culminating Projects

This project aimed to ask the question, “How does digital etiquette, or netiquette, lead to socialization of self-presentation on Instagram?” I interviewed 15 students classified as "Generation Z" who attend a northeastern university and have an Instagram account. This was done using a convenience sample of participants who were asked to participate in the interview. Done by the convenience of the individuals who were at the location at the time. The results indicate a disconnect between wanting to be seen as a “good person” and the means used to paint this image. Netiquette plays a role in crafting self-presentation, as …

Computational And Molecular Modeling Of Asphaltene Aggregation And The Effect Of Radicals And Nonradicals, Lyla Salyani

Theses, Dissertations and Culminating Projects

Asphaltenes are the heaviest component of crude oil consisting of a wide range of polyaromatic compounds with molar mass in the range of 500-800 g/mol. Asphaltenes tend to aggregate and form nanoclusters which lead to clogged pipelines. Understanding asphaltene aggregation has been a long-standing effort of industry and academia. Such systems are a typical example of systems studied to understand the impact of non-covalent interactions that drive the aggregation. Interactions that can be found to contribute to the stability of these aggregates can be π-π stacking, dispersion forces, and pancake stacking. A small fraction, 3%-4%, of the asphaltenes exist as …

Relationships And Recovery: Social Factors In Alcoholics Recovery, Elizabeth Moe

Theses, Dissertations and Culminating Projects

Introduction. Recovery is a process of change through which individuals improve their overall wellbeing, live self-directed lives, and strive to reach their full potential. In recovering from alcohol and substance use, there are many paths one may take to reach recovery, but engagement with new social circles and communities has been shown to be the most effective. This leads to the research question: what is the role of relationships during alcohol recovery? Methods. This mixed-methods study uses both qualitative and quantitative data. Quantitative data from the National Alcohol Survey was used to compare the effects and perceptions of drinking on …

An Invasion Of The Intimate Sphere: The Manipulation Of Libido Under Totalitarian Regimes, Elyssa Lucero

Theses, Dissertations and Culminating Projects

This paper examines the temporal nature of libidinal control in the totalitarian systems represented in George Orwell’s Nineteen Eighty-Four and Aldous Huxley’s Brave New World. Arguing that the most enduring forms of domination operate through the reorganization of desire, the essay explores how regimes intervene in familial, romantic, and social attachments to redirect affective energy towards the state. Orwell depicts a primitive, reactive phase of control in which attachments are violently ruptured, whereas Huxley imagines an advanced system that operates through preemption, never allowing attachments to form. Drawing on Freud’s theory of redirected libido, Berlant’s theory of Cruel Optimism, Marxist …

Analysis Of Collective Behavior In Living And Nonliving Systems, Kaitlyn Cohan

Theses, Dissertations and Culminating Projects

This thesis aims at understanding the phenomenon of of self-organization in complex dissipative systems, living and nonliving. Dissipative systems are characterized by their search for energy, interactions with their surroundings and the production of entropy, all of which result in the creation of stable structures or patterns, which persist as long as the initial environmental conditions are maintained. The two specific models that we chose to study here are (a) Futbol (or Soccer) and (b) a chemical system involving free-floating menthol crystals floating on a fluid surface to represent nonliving systems. Using experiments and mathematical models, we will try to …

Investigation Of Curing And Degradation Mechanisms In Lead White Oil Paint Systems: Impact Of Methyl Linoleate On Paint Matrix Formation And Solvent Extractability, Andrea Serrano Trujillo

Theses, Dissertations and Culminating Projects

Oil-based paints composed of drying oils and lead-containing pigments undergo complex chemical transformations during curing that influence long-term stability and degradation. Despite centuries of use, the molecular mechanisms governing oxidative polymerization and additive incorporation in lead white oil paint systems remain incompletely understood. This study investigates the role of methyl linoleate, a monoester analog of linoleic acid, in the curing and degradation pathways of lead carbonate and linseed oil paint films. A deep focus was placed on determining whether methyl linoleate becomes chemically integrated into the developing polymeric network or remains as an extractable and unbound component, as this distinction …

Constant Connectivity To Work, Health Behaviors, Physical Symptoms: Exploring Boundary Management Practices That Can Help, Christina Christodoulou

Theses, Dissertations and Culminating Projects

The workday inevitably exposes employees to numerous demands that induce stress reactions. Without sufficient recovery (i.e. returning stress reactions to baseline), individuals risk experiencing chronic psychological, behavioral or physical strains. With the rise of constant connectivity to work, recovery is becoming more of a challenge. However, research on the recovery-related consequences of constant connectivity, particularly its impact on health behaviors and physical health outcomes, remains scarce. To fill this gap in the literature, this research explored the relationship between constant connectivity, boundary management practices, health behaviors, and physical symptoms using a mixed-methods, multi-study design. A mixed methods pilot study (N …

Navigating Faith And Sexuality: Christian Pastors' Experiences In Providing Pastoral Care For Lgbtq+ Youth, Keith I. Raymond

Theses, Dissertations and Culminating Projects

Within the Christian context, religion and sexuality are often cultural factors that shape the identity development of LGBTQ+ youth, with congregational stance (affirming, tolerant, non–affirming) and individual religiosity/spirituality serving as protective or risk factors (Crockett et al., 2018; Raedel et al., 2020; Yarhouse & Sadusky, 2021). Christian pastors’ theology, relational ministry approach, and pastoral skills influence how they engage with and care for queer youth, yet the professional ties between pastors and LGBTQ+ youth remain underrepresented in counseling literature. Guided by queer theory, this qualitative case study examined how Christian pastors understand and navigate pastoral care for LGBTQ+ youth within …

Performative Racial Allyship And Ally Ambivalence: A Qualitative Study, Peter D. Goldie

Theses, Dissertations and Culminating Projects

Racism is rampant in and outside of higher education institutions (HEIs). Preliminary research has found that white allyship--or white people's efforts to dismantle racism by partnering with People of Color--can be beneficial to Black communities when done authentically and in ways that center Black voices, perspectives, and liberatory goals. However, a growing body of scholarship has found that white people seldom show up as allies in meaningful ways. Instead, they frequently resort to performative racial allyship (PRA), or behaviors that are meant to signal solidarity with a marginalized racial group yet are superficial and self-serving. To support effective antiracism efforts, …

Engaging College Students With Eating Disorder Symptoms In Digital Mental Health Interventions, Emily Judd

Theses, Dissertations and Culminating Projects

Background: Most college students with elevated eating disorder (ED) symptoms do not receive mental health treatment. These students commonly report preference for self-management and lack of perceived need for therapy as barriers to seeking help and engaging with mental health services. Screening surveys and digital mental health interventions (DMHIs) may help address these perceived barriers to treatment. Evidence suggests that DMHIs can be effective at reducing ED symptoms. However, student engagement (e.g., uptake and adherence) with DMHIs is low, which significantly limits their effectiveness. Objective: We adapted an engagement strategy for DMHIs, known as the Supporting Technology Engagement for Prevention …

A Pilot Study Of A Culturally Responsive Cognitive-Behavioral Intervention For Black American High School Students With Social Anxiety, Hannah Thomas

Theses, Dissertations and Culminating Projects

Cognitive-behavioral interventions have been shown to be effective for treating social anxiety, yet few have been evaluated for racially and ethnically minoritized youth, including Black American adolescents. These interventions also do not address sociocultural factors, including racial discrimination and mental health stigma, that may shape the experience of social anxiety among Black American youth and serve as barriers to care. Therefore, the aim of this study was to conduct a pilot evaluation of the feasibility, acceptability, and preliminary outcomes of Interacting and Changing Our Narratives (ICON), a culturally-responsive, school-based cognitive-behavioral group intervention for Black American high school students with social …

Agentcite: Trustworthy Ai Agents For Information Verification Across Referenced Documents, Eymen Yigit

Master's Theses

This thesis presents AgentCite, a multi-agent framework for automated verification of referenced numerical data in research documents. The framework employs a hybrid design in which LLM-based agents handle document understanding and evidence retrieval, while deterministic components manage structured parsing and value comparison, improving consistency and reproducibility while reducing token consumption and execution time compared to fully agentic approaches.

AgentCite consists of three autonomous agents: a Negotiator, a Main Document Agent, and a Source Documents Agent, coordinated through a fixed tool-call pipeline. The Negotiator orchestrates verification by extracting tabular data from the main document, retrieving evidence from per-source vector stores, and …

Probing Representational Emergence In Large Language Models, Shawn Ismail

Master's Theses

This thesis investigates whether abrupt behavioral gains in large language models under scaling are accompanied by systematic changes in internal representations. It combines a behavioral screen of 65 tasks per family with targeted layerwise probing across eight decoder-only, open-weight model families. Behavioral emergence is defined for each family-task trajectory using an empirical jump detector, with segmented regression retained only as a diagnostic. The representational follow-up analyzes 27 selected MMLU subtasks shared across all families, spanning 37 checkpoints and 216 family-task units.

For each follow-up checkpoint, frozen linear probes are trained on every layer's hidden states to measure how much task-relevant …

Ai-Enabled Autonomous Visual Navigation In Complex And Data-Constrained Agricultural Environments By Leveraging Image Augmentation And Translation Methods, Robel Mamo

Master's Theses

The field of agricultural robotics remains one of the most underexplored domains within the broader robotics community. As a result, there is a scarcity of robust, scalable, and adaptable robotic systems capable of operating under the highly variable conditions of real-world farms. Visual navigation is essential for field autonomy, yet state-of-the-art perception models rely heavily on large annotated datasets and consistent environmental conditions. This thesis addresses these limitations by proposing two novel frameworks to enhance model robustness against structural occlusions, environmental variability, and low-visibility conditions under nighttime settings. First, I introduce Crop-Aligned Cutout (CA-Cut), a spatially guided augmentation method that …

Toni Morrison's New World Black Woman: Refuting, Deconstructing, And Redefining Black Women's Identity, Victoria L. Bell

Master's Theses

Abstract

Through critical analysis of media: literary works, performance, and television, this thesis explores the prejudices, silencing, dehumanizing, sexualization, and marginalization of Black women, their bodies, identity, and trauma inflicted by White-authored texts, specifically the American canon. I analyze the works of Black women authors, scholars, and activists, who counter the false representation of the patriarchy. Their literary works refute, deconstruct, and redefine the canon’s distorted, racial and gendered stereotypes, later to be named controlling images.  While narrating the Black woman’s authentic self, experience, body, and womanhood they reclaim space, authenticity, and agency.

In my research and analysis, the central …

Deep Learning For Predicting Impact Energy And Compression After Impact Strength Of Composite Materials Using C-Scan Images, K. T. Tan, Jason P. Mack, Faizan Mirza, Zhong-Hui Duan

University Research

Traditional assessment of post-impact performance in carbon fiber reinforced polymer (CFRP) composites often relies on simplified scalar metrics that fail to capture the complex spatial interactions driving failure. This study addresses this limitation by developing an automated, end-to-end deep learning framework that shifts from manual feature extraction to the direct interpretation of raw damage morphology from ultrasonic C-scans. Using a ResNet18-based convolutional neural network (CNN) trained on 1,428 augmented images, the model achieved coefficients of determination (R2) of 0.7948 ± 0.0847 for compression after impact (CAI) strength and 0.9436 ± 0.0098 for impact energy. Beyond prediction, this dual-purpose methodology serves …

Electronic Theses and Dissertations

The purpose of this qualitative study was to examine the characteristics and contextual factors that general education and special education teachers perceive as essential for effective co-teaching partnerships in high school inclusive classrooms. The study, which involved in-depth interviews with general and special education teachers in co-teaching partnerships, was conducted within a constructivist paradigm to shed light on interpersonal, communicative, and systemic variables that contribute to a positive, productive co-teaching experience. Purposeful sampling was employed to select general and special education teachers who were part of co-teaching partnerships. Thematic analysis was used to analyze data from semi-structured interviews, and an …

Attendance Matters: Incentive Programs And Chronic Absenteeism In Elementary Schools, Aubryn Street

Electronic Theses and Dissertations

Chronic absenteeism is a common challenge in elementary education. Schools often use attendance incentive programs, such as rewards or recognition, to encourage students to attend regularly. However, it is not always clear whether these programs actually improve attendance. This study examined whether attendance incentive programs are effective and how school staff view and use these programs.

This mixed-methods study used both school attendance data and interviews with school personnel. Attendance data from two school years showed that schools with incentive programs did not have lower absenteeism rates than schools without them. However, attendance improved overall from one year to the …

Bergsonian Blend: Subjective Temporality Within Modernist Aesthetics Of Mental Illness, Lydia Victoria Gervais

Electronic Theses and Dissertations

Henri Bergson was a modernist French philosopher who wrote extensively on the topic of the lived experience of time, which he called durée, or duration. His contemporary, Sigmund Freud, was developing psychoanalytic theory in a growing field of psychological study, which serves as a prominent ancestor to modern psychiatry and current psychoanalytical literary studies. Fiction writers of the 1900s absorbed the zeitgeist of melded chronology and consciousness, interweaving themes of time and trauma in their works. Utilizing Henri Bergson’s durée as a philosophical framework, I examine the moralization of time-consciousness in connection with mental illness and investigate representations of …

Stability Of Paraffin-Insulated Nitrogen-Doped Carbon Fiber Ultramicroelectrodes, Maxwell H. Kwakwah

Electronic Theses and Dissertations

Nitrogen-doped carbon materials can facilitate the reduction oxygen-oxygen bonds, a key step in electroreduction of both O₂ (an important reaction in energy applications) and H₂O₂ (an important reaction in sensing and biosensing). Our lab previously demonstrated that thermal decomposition of urea in the presence of carbon fiber (CF) results in an N-doped carbon material that exhibits good electrocatalytic properties for H₂O₂ reduction. However, previous methods of insulating single N-doped CF via laser heating of borosilicate capillaries and epoxy to prepare ultramicroelectrodes (UMEs) seemed to adversely affect surface nitrogen contents and electrocatalytic properties. More recent work that utilized paraffin to …
