Probing The Roles Of Connexin 43 Hemichannels In A Mouse Model Of Alzheimer's Disease, Madison Treasure-Areno

All Graduate Theses and Dissertations, Fall 2023 to Present

Alzheimer’s disease is a progressive disorder involving neuronal death and cognitive decline, such as memory loss and changes in personality. One feature of the disease is buildup of abnormal protein called amyloid-beta in the brain. Amyloid-beta may activate support cells called astrocytes, triggering them to release large amounts of chemicals, possibly harming nearby cells. This study set out to examine the roles of the channels on astrocytes involved in releasing these chemicals, called connexin 43 hemichannels. Using a mouse model of Alzheimer’s disease, this study blocked the hemichannels using the drug Tonabersat, and measured spatial learning and memory in a …

Exclusive By Design: Engineered Scarcity And Consumer Behavior In Fashion Drops, Caroline H. Meyer

Marketing Undergraduate Honors Theses

The drop business model centers on releasing small batches of products, often without much notice, on a recurring or semi-regular schedule. These limited releases, or "drops," sell out quickly and rarely restock, creating urgency and making each product feel exclusive. Consumers are trained to anticipate launches, check for updates, and act fast within minutes to secure items before they’re gone. By tapping into psychological drivers such as scarcity, fear of missing out (FOMO), and the desire for social belonging, the drop model flips traditional retail logic. Instead of keeping shelves full, it withholds. Instead of lowering prices to drive sales, …

Albany City As A Case Study In Language Mapping, Storm Pupina

Linguistics

This thesis uses Albany, NY, as a case study in urban language mapping, following the example of many other language mapping projects, most notably the NYC Language Mapping Project. Albany's languages and linguistic features were analyzed to better understand the area's linguistic ecology and ongoing heritage-language maintenance efforts. Various types of American Census data were compared to reach the conclusions. Despite not being a major city, Albany is bustling with both new and old language communities. Similar efforts with more varied data-gathering tactics would greatly benefit other American urban landscapes.

A veteran of the American Civil War, Captain Munson visited Cuba following the war’s conclusion and became involved in Cuba’s oil and sugar industries, gradually becoming involved in the international sugar shipping trade. An 1890 innovation in shipboard technology and its impact on the Cuban American molasses trade was a moment that established a multi-generational maritime empire, officially incorporating the Munson Steamship Line shortly after the American intervention in the Cuban War of Independence and expanding throughout the Atlantic. His …

Factors Affecting Pedestrian-Vehicle Conflicts: An Empirical Analysis, Christo D. Jamo

Honors Scholar Theses

The number of pedestrian deaths increased by 78% between 2009 and 2023, while other motor vehicle crash deaths increased by 13% in the same period [1]. To identify potential pedestrian safety measures, this study analyzed the effects of location-based demographics, pedestrian phasing type, and other physical infrastructure and behavior variables on the probability of pedestrian-vehicle conflicts at signalized intersections, which is a surrogate measure of crash risk. Data were collected from 55 intersections in Connecticut, and the pedestrian-vehicle interactions were classified by severity based on the Swedish Traffic Conflict Technique: undisturbed passage, potential conflict, minor conflict, or serious conflict. Because …

Morphological Evolution And Sediment Budget Of A Flood-Tidal Delta On The Rio Grande Delta Plain: Bahia Grande, Texas, Usa, Aleen Pertuz Paz

Theses and Dissertations

The Isabel Delta is a recently formed flood-tidal delta within the restored Bahia Grande system on the Rio Grande Delta Plain, Texas, USA, where renewed tidal connectivity has created conditions for rapid sediment buildup and landform evolution. This study quantified morphological changes from 2008 to 2025 using satellite imagery. It assessed sediment retention by comparing the effective sediment discharge required to reproduce observed delta growth with field-based estimates of sediment supply derived from channel hydrodynamics, cross-sectional area, and suspended sediment concentration. The delta expanded steadily throughout the study period, with increases in bar, channel, and total surface area, and an …

Dyadic Agreement In And Task Correlates To A Measurement Of Conversational Success, Samantha Budge

All Graduate Theses and Dissertations, Fall 2023 to Present

Successful conversation matters for social connection, wellbeing, and quality of life, but people do not always agree on whether a conversation was successful, even when they participated in the same interaction. Conversation is also commonly measured through task success, even though it’s unclear how task success correlates to how successful a conversation feels. This study examined how conversational success is experienced by different conversation partners and whether feeling successful in a conversation is related to how well a task is completed.

Participants took part in a structured conversational task and then rated their own conversational experience using a self-report questionnaire …

"Am I A Man Or A Muppet": A Rhetorical Analysis Of Generative Ai’S Representation Of Gender, Jessica Boaz

Electronic Theses and Dissertations

This thesis examines how generative artificial intelligence constructs and performs gender roles through a rhetorical analysis of the fully AI-generated podcast Fairytale Forensics. Drawing on theories of constitutive rhetoric, stereotyping, and McLuhan’s approach to the medium, this thesis investigates how AI-generated hosts interpret classic fairy tales while simultaneously reproducing and negotiating gender norms through the lens of prosopopoeia, metonymy and synecdoche. These performances rely on normative gender stereotypes that align with broader societal expectations, thereby potentially reinforcing existing cultural assumptions about masculinity and femininity. Ultimately, it demonstrates that AI-generated discourse does not merely reflect human biases but actively participates in …

This study examined whether Christian-based community engagement served as a protective factor against loneliness among college students. Grounded in Social Support Theory, the study assessed associations among loneliness, general social support, church-based support, religious coping, institutional integration, …

Body Worn Cameras For The Madison Police Department, Caleb Wright

Master of Public Administration Capstone Papers

Body-worn cameras for law enforcement officers can ensure accountability of the officers and transparency to the public. Though body-worn cameras have become increasingly popular in police departments, some departments do not use them. The Madison Police Department is one of these departments. Body-worn cameras have been implemented with policy models in many surrounding departments in Wisconsin and have proved to hold officers accountable and ensure transparency during complaints and cases. Leveraging literature on integrated policy approach and policy implementation, this capstone paper summarizes the needs and benefits of body-worn cameras for the MPD. This paper contributes to broader debates on …

Regional Economic Impacts And Emission Responses Under Solar Radiation Modification, Jenny Bjordal, Evelien Van Dijk, Henri Cornec, Anthony A. Smith Jr, Trude Storelvmo

Cowles Foundation Discussion Papers

Solar Radiation Modification (SRM) has been proposed as a potential tool to limit increases in global or regional temperatures caused by anthropogenic greenhouse gas emissions. While previous research has extensively examined the climate system’s response to various SRM strategies, as well as their aggregate economic consequences, the regional distribution of economic impacts has received less attention. In this study, we use NorESM2–DIAM—an Earth System Model coupled to a high-resolution integrated assessment model—to assess the economic impacts, measured in GDP per capita, in an idealised SRM scenario where incoming solar radiation is reduced by 1%. Our results suggest that, relative to …

Beyond Exposure: Predicting Ai Adoption Based On Comparative Advantage, Ilse Lindenlaub, Ryungha Oh, Maria Alejandra Rodriguez, Laura Veldkamp

Cowles Foundation Discussion Papers

We document and explain the gap between measures of AI exposure and measures of AI adoption in the workplace. This leads us to propose a new AI adoption index based on comparative advantage. Using the representative German DiWaBe employee survey linked to worker and establishment information, we compare worker-reported AI use to prominent exposure measures and find that the relationship is weak. Motivated by this gap, we develop a framework in which adoption depends not only on technical feasibility—AI’s absolute advantage measured by exposure—but on profitability—AI’s comparative (dis)advantage relative to a specific worker—balancing AI productivity against AI user costs and …

From People’S War To People’S Rule: Rebel Governance And The Foundations Of Inclusive Democracy, Bhishma Bhusal, Michael Callen, Rohini Pande, Soledad Prillaman, Deepak Singhania, Apurva Subedi

Cowles Foundation Discussion Papers

How does wartime rebel governance shape post-conflict institutions? We study this in Nepal, where the Maoist People's War (1996–2006) dismantled a 240-year caste-based monarchy and ended with Maoists entering democratic politics. During the conflict, Maoists established sub-national “People’s Governments” that administered justice, collected taxes, and delivered local services. Using a spatial regression-discontinuity design, we show that exposure to People's Governments increased political knowledge and participation especially among historically marginalized indigenous groups (Janajatis). Exposure also reshaped party institutions and inter-party competition: candidate-selection committees in more exposed areas have 26 percent more Janajati members who, drawing on novel implicit-attitude data, exhibit less …

A Novel Approach To Creativity Assessment: Forced Pairwise Ranking With Large Language Models, Phillip R. Gregory Jr

Master's Theses

Assessing creativity at scale remains a persistent challenge in cognitive science, as human raters are costly, slow, and often inconsistent in their judgments. This thesis introduced a novel framework for automated scientific creativity assessment using forced pairwise ranking, in which fine-tuned large language models compared response pairs and determined which was more creative. Five empirical studies were conducted using Llama-2-7B and Llama-2-13B models adapted via LoRA fine-tuning and benchmarked against human scored responses from the Scientific Creative Thinking Test. A regression baseline achieved Pearson �� = .74 on the test set, matching the human inter-rater ceiling reported in the literature. …

Building Collaborative Capacity For Coexistence With The Montana Beaver Working Group, Shane Randle

Graduate Student Portfolios, Professional Papers, and Capstone Projects

Despite beavers’ recent surge in popularity, prevailing negative attitudes and the persistence of beaver removal practices remain obstacles for those advocating living with beavers. The Montana Beaver Working Group (BWG) advances beavers’ role in ecological and community resilience through members’ collaborative efforts, including beaver-related restoration and conflict resolution projects. Bringing together people with diverse values and perspectives, the BWG builds collective understanding, develops a holistic vision for beavers in Montana, and supports members in pursuing it. As the group’s impacts and membership have grown, so too has their need to adapt. For my Civic Engagement Project, I strengthened the BWG’s …

Face Representations In The Fusiform Face Area, Krisha Orgo

Electronic Theses, Projects, and Dissertations

Faces are among the most socially significant stimuli humans encounter, requiring recognition not just at the category level but at the level of individual identity. While the fusiform face area has been established as a dedicated region for face processing, whether it encodes distinct representations for different individuals or simply detects the presence of a face remains an open question. Evidence for identity-specific coding in the brain has come primarily from invasive single-neuron recordings in epilepsy patients, leaving open whether the same principles govern face processing in healthy populations. The present study addressed this gap using scalp electroencephalography to examine …

Assessment Of Super Absorbent Polymer In Soybean Cultivation Under Variable Irrigation Conditions In Nebraska, Ankit Chandra, Abia Katimbo, Ronaldo Marchezan, Martha Nabaggala

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

Water limitation is a primary constraint to soybean productivity in both irrigated and rainfed systems. Soil-applied superabsorbent polymers (SAPs) have been proposed as a strategy to buffer crops against episodic drought stress; however, their physiological and agronomic performance under varying irrigation regimes remains insufficiently quantified. Here, we evaluate three biodegradable polymer formulations: broader granules (BB), original granules (OG), and powder (PWR) applied at low (17.7 lb/ac) and high (120 lb/ac) rates under full (100% ET), reduced (50% ET), and no irrigation conditions in western Nebraska. Polymer application had negligible effects under full irrigation, with yields comparable to untreated controls. Under …

Hidden Workload In Emergency Medicine: Examining The Role Of Outside-Of-Shift Duties In Emergency Physician Fatigue, Sarah Meyer

All Theses

Emergency physicians (EPs) face high rates of burnout. In addition to well-known stressors, such as fatiguing shift work schedules and intense emotional and cognitive demands faced during clinical shifts, many EPs must also attend to certain outside-of-shift duties (OSDs)–extra-clinical role responsibilities that are expected but not always formally tracked or compensated. These duties often occur during times when EPs are expected to rest and recover from shift work. Despite concerns surrounding burnout in emergency medicine and beliefs among EPs that OSDs contribute to burnout, the effects of OSDs have rarely been studied. Using daily and weekly surveys across 28 days, …
