A Framework For Enhanced Circular Product Development With Total Life Cycle Considerations, Gisele Bortolaz Guedes, Fazleena Badurdeen, Ibrahim S. Jawahir

Mechanical Engineering Faculty Publications

Advancing circular product development (CPD) requires design decisions that account for the entire product life cycle, from material sourcing and manufacturing to use and end-of-use (EoU) stages, to ensure enhanced sustainability performance. Existing Product Development Process (PDP) models tend to emphasize isolated phases or perspectives with limited explicit consideration of the total product life cycle. This hinders the systematic embedding of various Circular Economy (CE) strategies during product development. Thus, designers and engineers lack a unified framework to determine when and where critical decisions should be made to effectively incorporate CE strategies such as effective resource selection, extending product use-life, …

Aggregation Bias In Multi-Industry Economic Contribution Analysis: The Case Of Kentucky Forest Sector, Domena A. Agyeman, Thomas Ochuodho, Omkar Joshi

Forestry and Natural Resources Faculty Publications

Closely related industries are often aggregated in US forest sector economic contribution analysis, yet the choice of aggregation scheme can influence results. The Impact Analysis for Planning (IMPLAN) system is the most widely applied input–output model for forest economic contribution analysis in the US. In IMPLAN, the level of industry aggregation determines which inter-industry transactions are restricted, thereby influencing the magnitude of estimated indirect and induced effects. Although IMPLAN practitioners can model individual industries to avoid aggregation bias, they must still decide whether to analyze forest industries as a single group, as traditional subsectors, or individually. This decision can alter …

Muted Trumpets As A Sonic Representation Of Isolation Or Solitude, Caroline Reyner

Schultz-Werth Award Papers

The sound of a trumpet can be used in a variety of applications. This is due to its ability to adjust its timbre to fit different situations. Among the most common adjectives applied to brass instruments, especially trumpets, are terms associated with bright, metallic, or brassy qualities (Wallmark 587-588). While these are timbral qualities of the trumpet, they are not the only ones of which the trumpet is capable. According to ACTOR Research, the following timbres of the trumpet have been extracted from various orchestration treatises – agile, blaring, brassy, bright, brilliant, crisp, flexible, piercing, powerful, responsive, sharp, smooth, and …

Evaluating The Effects Of Biochar-Based Slow-Release Nitrogen Fertilizers On Camelina Growth And Development In Greenhouse, Lily Geffre

Schultz-Werth Award Papers

The world’s dependence on conventional fertilizers such as urea allows for significantly increased crop yields but has also greatly contributed to the environmental degradation of agricultural lands and surrounding areas. Biochar-based slow-release fertilizers (SRFs) are an ideal alternative to conventional fertilizers, as they enhance nutrient uptake and retention, improve soil properties, and reduce nutrient leaching and volatilization. This study evaluated the effects of biochar-based SRFs, in comparison with traditional non-SRF fertilizers, on the vegetative growth, physiological growth, and yield of Camelina sativa under greenhouse conditions. Conventional urea yielded the best overall crop results, but a coated biochar-based urea SRF achieved …

Beyond Fixed Thresholds: Per-Label Calibration For Fine-Grained Emotion Detection On The Goemotions Dataset, Sai Puneet Naga Venkata Subramanyam Patchipulusu

Selected Full-Text Master Theses 2021-

This study investigates the effectiveness of five community fine-tuned transformer models for fine-grained emotion detection on the GoEmotions dataset: SamLowe/roberta- base-go_emotions (RoBERTa-base), cirimus/modernbert-base-go-emotions (ModernBERT), mrm8488/deberta-v3-base-goemotions (DeBERTa-v3-base), bhadresh-savani/bert-base-go- emotion (BERT-base-cased),and tasinhoque/distilbert-go-emotions (DistilBERT) . While the original GoEmotions research by Demszky et al. (2020) established a BERT-base baseline with a macro-F1 of 0.46, this thesis extends that work through independent empirical evaluation of five derivative models, systematic per-label threshold optimization, and comparative analysis of architectural trade-offs across the full transformer model family. Using the GoEmotions simplified test split (5,427 examples across 28 categories), all five models were evaluated at a fixed 0.5 …

Beyond Perspective: A Spectacular History Of The Three-Dimensional Image Through The Stereoscope, The View-Master, And Marcel Duchamp, Margaret Hankel

Bryn Mawr College Dissertations and Theses

This dissertation examines the technology of the stereoscope and its threedimensional image called a stereograph. Invented in 1838 by the British physicist Charles Wheatstone, the stereoscope produces an optical illusion in which depth and volume appear to project both inward and outward from a stereograph’s two-dimensional surface. This spectacular, three-dimensional image enjoyed widespread popularity in the nineteenth, twentieth, and twenty-first centuries as the technology underwent multiple reinventions. By examining stereoscopy with an art historical lens, this dissertation considers the technology in relation to the tradition of perspective and illusionism in art. The stereograph’s emergence alongside photography marks an intensification of …

Examining Structural Stigma In American Policy Making: A Case Study Of California Senate Bill 403, Anjali Bushan

Bryn Mawr College Dissertations and Theses

The South Asian American community is one of the fastest growing communities in the United States (Budiman & Ruiz, 2021). While research has explored various aspects of the South Asian American diaspora, limited research has focused on the caste system in the diaspora. This study examined caste on a macro level in American policy making. Using a qualitative case study design, it explored how the policy making process of California Senate Bill 403, a bill intended to prohibit caste discrimination, impacted structural stigma on caste and demonstrated interest convergence between caste supremacy and white supremacy in the United States. Findings …

Goodbye, Nomcompetes? Policy Diffusion And State-Level Reforms, Lorenzo G. Luisetto, Norman D. Bishara

Law Faculty Articles and Essays

Post-employment non-competition agreements (“noncompetes”) have been part of the common law dating back to at least 1414. The past 16 years have seen an unprecedented wave of scrutiny that is mostly aimed at curtailing these agreements, culminating in the contentious 2024 Federal Trade Commission’s (FTC) attempted noncompete ban. With the broad FTC ban on hold for the foreseeable future, the spotlight shifts back to the states where innovation in noncompete policy is blossoming. In this study, we systematically explore the legislative and policy trends reshaping the U.S. noncompete landscape. We propose a novel typology of these reforms and apply a …

Previsit Ai: A Retrieval-Augmented Generation For Patient Readiness In Clinical Encounters, Rolande Umuhoza

All Graduate Theses, Dissertations, and Other Capstone Projects

With healthcare systems under growing pressure from rising patient volumes and shrinking consultation windows, improving how patients communicate with physicians has become essential to delivering quality care. Yet patients routinely arrive at appointments unable to clearly describe their symptoms, recall their medical history, or articulate concerns, contributing to miscommunication, diagnostic inefficiency, and pre-visit anxiety. This study introduces PreVisit AI, a conversational system designed to address this gap through structured, knowledge-based patient preparation. The system is built on a Retrieval-Augmented Generation (RAG) architecture combining HuggingFace sentence embeddings (all-MiniLM-L6-v2), a Chroma vector store, and Google’s Gemini language model over a curated seven-document …

Health, Patents, And Path Dependence: India's Pharmaceutical Crossroads, Jacie Bissell

Michigan Technology Law Review

This paper examines how India’s historical commitment to affordable medicine and public health continues to shape its pharmaceutical patent regime, even as the country aspires to become an innovation-driven economy. Through the lens of path dependence, the paper explores how India’s legal and institutional frameworks have created structural constraints on policy reform. Focusing on key moments such as the Patents Act of 1970, the landmark Novartis decision, and India’s evolving stance on the TRIPS waiver during the COVID-19 pandemic, the paper analyzes the tensions between fostering pharmaceutical innovation and maintaining access to affordable medicines. While recent procedural reforms and judicial …

Recovering From The Ego Death Of The Internet: How The Communications Decency Act Has Shattered Cyber-Libertarianism And The Non-Exceptionalist Move Toward A Brighter Digital World, Peyton Friedlander

Michigan Technology Law Review

For nearly thirty years, the legal framework for analyzing liability for claims of tortious wrongdoing on the Internet has been governed by Section 230 of the Communications Decency Act (“CDA”). However, much has changed since the Act’s inception. Since Congress enacted the CDA, courts have interpreted its provisions far beyond their original meaning, creating a regime that ultimately destroys a prospective plaintiff’s ability to recover the equitable remedies once available to those seeking redress for online invasions of privacy and reputational harms.

As the Internet continues to grow and changes in technology rapidly develop, it is time to re-center equitable …

Conversational Ai And Human-Centered First Amendment, Inyoung Cheong

Michigan Technology Law Review

Human-centered artificial intelligence (AI) is premised on the idea that humans must remain the ultimate locus of agency in technological systems. First Amendment jurisprudence has displaced this commitment. By extending speech protection to algorithmic architectures, the judiciary has forged a doctrinal shield that insulates corporate actors from the consequences of their products. Conversational AI deepens this crisis through intimate incursions into the epistemic and emotional registers of the self. Emerging approaches that anchor First Amendment coverage to the controllability or traceability of AI outputs offer no stable solution. Policy-level design choices such as safety guardrails and alignment processes can readily …

Countryside Aflame: Fire As A Hazard In The Rural Philippines, 1850–1950, Greg Bankoff, Marie Beatriz D. Gulinao, David O. Lozada Iii, Mary Donna Grace Cuenca

History Department Faculty Publications

Fire has shaped human evolution, social organisation, and technological development, yet modern fire science remains anchored in categories derived largely from Western experience: wildland fires, the wildland–urban interface, and urban conflagrations. These frameworks obscure a fourth, largely overlooked regime– village fire– rural settlements that lack the structural protections, materials, and services characteristic of urban areas. In the Philippines, where rural settlement dominated into the twentieth century, village fire was the principal way people encountered fire risk. Using evidence from the Historical Data Papers (1951), this study reconstructs a village fire regime marked by highly combustible construction, new technological sources of …
