Spatial Control Of Nonlinear Interactions In Multimode Fibers, Kabish Wisal

Yale Graduate School of Arts and Sciences Dissertations

In recent years, there has been significant advancement in controlling optical scattering by structuring the wavefront of the incident light, or `wavefront shaping'. Most applications of wavefront shaping have focused on linear scattering, but there is a growing interest in tailoring nonlinear scattering. In this thesis, we explore a new approach based on wavefront shaping for suppressing certain instabilities induced by nonlinear scattering in passive and active multimode fibers (MMFs). Specifically, we focus on suppressing stimulated Brillouin scattering (SBS) and transverse mode instability (TMI). A key motivation for our work is power scaling in high power fiber lasers and amplifiers, …

Deep Learning For Large-Scale Harmonic Analysis: A Corpus Study Of Western Harmony From 1700-1900, Malcolm Sailor

Yale Graduate School of Arts and Sciences Dissertations

This dissertation trains deep learning models for the Roman numeral analysis and applies these to the analysis of a corpus of over 12,000 movements of Classical music composed between 1700 and 1900. The Roman numeral analysis models obtain performance that is, as of this writing, state of the art. At the same time, this is the first work of scholarship to employ such models at scale for a music-theoretic corpus study. Consistent with music-historical expectations, this corpus study shows that, along many dimensions, such as the distribution of keys employed or the proportion of chromatic scale degrees, harmonic complexity rose …

Impact Of Digital Courseware Use On Online Student Sense Of Belonging And Potential For Building An Online Community Of Inquiry, Kat Klement

All Graduate Theses, Dissertations, and Other Capstone Projects

Though interest in online education is rising, online programs have a lower retention rate than do in-person programs and a correspondingly higher dropout rate. One factor that drives online student retention is the degree to which students feel a sense of belonging in their online courses. As more interest in online education leads to larger course sizes and more online sections, instructors may turn to digital courseware offered by publishing companies to increase student engagement and provide formative assessment. Yet research shows little consistency in the impact of digital courseware use on course grades. The studies in this thesis explored …

Teaching Object-Oriented Design Through Interactive Uml: A Dual-Approach Framework For Code-Based Generation And Direct Diagram Manipulation, Moses Kayuni

Masters Theses & Specialist Projects

This thesis introduces an interactive educational framework for teaching object-oriented design through UML class diagrams. The framework implements a dual-approach methodology: code-based generation, where students write Java code that automatically transforms into UML diagrams, and direct diagram manipulation, where students build diagrams by interacting with highlighted terms in problem descriptions. This approach addresses common challenges in teaching UML, including cognitive load difficulties, visualization problems, and the disconnect between code implementation and visual design. Built on the Mermaid diagramming framework, the system features a React frontend for diagram creation and manipulation, and a Flask backend that handles some code parsing and …

Makers Of Identity: Those That Hold It, Or Those That Create It?, Valentina K. Quintero

SPARK Symposium Presentations

Throughout the semester, the topic of AI potentially achieving personhood has been a deeply debated topic. Issues rise and fall depending on perspective, and there are still too many unknowns to be completely certain that AI has either managed to become a person or has not. One of the key details of personhood is the modern understanding of the word identity. This paper will go into the origins of the word and how it may have changed, and how it is important in regards to AI and its potential. Wittgenstein’s language games, personal opinion, and cultural influences will be explored …

The Economic And Environmental Impact Of Shinkansen And High-Speed Rail Infrastructure: A Comparative Analysis Of Economic Growth And Carbon Emissions Reduction, Dillan R. Victory

SPARK Symposium Presentations

The development of Japan's high-speed rail system, the Shinkansen, has played a pivotal role in the country's post-war economic resurgence. Introduced in 1964 with the Tokaidō Shinkansen, this transformative infrastructure investment significantly reduced travel times, bolstered economic activity around station hubs, and facilitated regional development by enabling urban decentralization. This paper explores the long-term economic benefits of high-speed rail, including its impact on land value, business expansion, and carbon emissions. The case study of the Linear Chuo Shinkansen, Japan's latest maglev project, underscores both the economic promise and the political resistance to expansion, particularly in regions such as Shizuoka.

Beyond The Editorial Analogy: First Amendment Protections For Platform Content Moderation After Moddy V. Netchoice, Alan Rozenshtein, Kyle T. Langvardt

Articles

This Article examines the Supreme Court’s 2024 decision in Moody v. NetChoice and its implications for social media platform regulation. In Moody, which addressed state laws requiring platforms to host certain content, the Court issued a complex set of opinions that left the scope of platforms’ First Amendment rights uncertain. On the procedural question of how such laws may be challenged, the Court provided a clear holding: it rejected facial challenges to broad content-moderation laws, instead requiring case-by-case analysis of how specific regulations affect different platform features—a shift that undermines the tech industry’s longstanding litigation strategy. But on the …

Women And Corporate Governance: Time Horizons And Stakeholder Analysis, June R. Carbone

Articles

This Article will build on my earlier work with Naomi Cahn and Nancy Levit to use the fate of women in individual companies to shine new light on the temporal orientations underlying corporate and labor and employment law and provide a basis for a new foundation for a combined approach. This Article will first explain why the shift to shareholder primacy, and the accompanying emphasis on short-term results tied to high stakes bonus pay, disproportionately short-changes female employees, whether in management or in line positions. The Article will maintain that it is not the shift to shareholder primacy in isolation, …

Abuse Of Power In The Workplace: The New Gender Discrimination Claims, June R. Carbone, Nancy Levit, Naomi Cahn

Articles

This article draws on our book, Fair Shake: Women and the Fight to Build a Just Economy, to show how the fight for gender equality has changed. Antidiscrimination laws took hold during an era of relative economic equality; the fight for gender equality was a fight to gain access to the rights of white men. Today’s economy creates much greater inequality and reserves the greatest rewards for a much smaller group, again predominately white and male, who can defy the rules and get away with it. In such contexts, anti-discrimination law premised on a fight for equality can provide only …

Obamacare For Homeowners Insurance: Fixing America's Broken Insurance Markets In A Time Of Climate Change, Daniel Benjamin Schwarcz

Articles

Over the last decade, homeowners insurance markets nationwide have experienced unprecedented instability due to climate change. These disruptions, which are likely to accelerate in the coming years, risk destabilizing real estate markets, triggering financial instability, and undermining the nation’s resilience to climate change. Despite these massive stakes, federal and state reforms to date have largely failed to result in more accessible and affordable homeowners insurance coverage that promotes climate change resilience. This Article offers a new way forward, arguing that today’s troubled homeowners insurance markets resemble the broken, state health insurance markets that pre-dated the 2010 passage of the Affordable …

Estimating Per-Infection Cost And Burden For Dengue And Zika As A Function Of Antibody-Dependent Enhancement, Christopher M. Kribs

Mathematics Faculty Publications - Archive

The complex immune interactions produced by the tetravalent dengue vaccine Dengvaxia have foregrounded the important role of antibody-dependent enhancement (ADE) in dengue infection. Some evidence exists that ADE may extend beyond the four dengue serotypes to Zika, a closely related flavivirus transmitted by the same mosquito species as dengue, and may also account for the increased severity of some cases. Estimates of the public health impact of dengue vaccination may then need to include its effects on the transmission of Zika in addition to dengue. This study gathers primary references to build estimates of per-case economic cost and disease burden …

Liability, Property, And Inalienability Rules In Employee Data Regulation, Matthew T. Bodie

Articles

Legal protections for workers’ data have usually taken the form of privacy protections designed to deter data processing that is excessive or invasive. Such protections generally fall into the category of liability rules, under which rights can be infringed as long as compensation is provided for the violation. As Guido Calabresi and A. Douglas Melamed have described in “Property Rules, Liability Rules, and Inalienability: One View of the Cathedral,” liability rules are contrasted with either property rules that prevent the involuntary transfer of rights or inalienability rules that prohibit rights transfers altogether. This article explores how property rules and inalienability …

The Cycle Of Giving:, Sarai Brown

BYU Asian Studies Student Journal

On one hot summer day in the middle of a 3-month stint studying Mandarin Chinese at National Chung Hsing University (NCHU) in Taichung, Taiwan, my friends and I were desperate to sate our appetites after class, even in the atrociously hot and humid conditions. Most of our little group was drawn to a 牛肉麵 niúròu miàn (beef noodle) shop, but the thought of hot soup on a day like this drove me and a couple of others to continue our search. We stumbled upon another outdoor restaurant—though “restaurant” is perhaps a loose term for the holey-tent-covered food stand with mismatched …

5. Teaching Excellence Fostered Through Institutional Collaboration: A Case For An Effective Assessment Rubric, Amanda Morris, Anna Kuthy

Documenting Teaching Excellence

Teaching excellence is a defining characteristic and ongoing challenge at small liberal arts institutions, where instructor independence and mission-driven education converge. Defining and measuring it in such contexts involves navigating instructor autonomy, institutional mission, administrative oversight, and accreditation requirements. This chapter presents a case-based approach to addressing these challenges at Brescia University, a small liberal arts school in Owensboro, KY. We offer an example of an implementable solution that fosters and documents teaching excellence while aligning with both generally accepted standards and the university’s mission. Additionally, we model a collaborative development process between the offices of the Academic Dean and …

6. The Creation Of A Teaching Excellence Framework: Defining, Measuring, And Facilitating Teaching Excellence, James Agutter, T. Adam Halstrom, Anne Cook

Documenting Teaching Excellence

Defining what constitutes teaching excellence is a crucial focus for faculty development to create deep learning opportunities in our classrooms and ensure our students’ success. However, establishing a single definition is challenging to standardize and quantify. We recognize outstanding teaching when we see and experience it — we all know the faculty members who spark curiosity, foster deep learning, and create memorable experiences for our students. Yet, how do we assess something so complex, nuanced, and profoundly influential? Excellent teaching varies based on the institution, the field, the context, the content, and the demographics of the students in a course. …

10. The Language Of Teaching Excellence: Describing Pedagogical Expertise Through A Framework Of Care, Beth Buyserie

Documenting Teaching Excellence

During my 20 years of college-level teaching, I have engaged in countless conversations where instructors communicate their passion for teaching, their commitment to student learning, the depth of their disciplinary expertise, their continued pedagogical innovations, and their thoughtful reflective practices. Yet often these same teachers confide that they find it quite challenging (sometimes nearly impossible) to write about their teaching for promotion—not because they are not strong teachers, but because the language expectations for documenting teaching accomplishments can be formidable. For example, at my particular institution, teaching-centered instructors are specifically directed in our role statements to “demonstrate excellence” in our …

Harmonic Analysis Of Currents Within Humboldt Bay, Caitlin J. Williams, Ula Brucker, Jaden Mccarthy, Noe Noe Camarillo, Taylor Juchau, Steven Gracy, Max Serrano, Karina Bernbeck, Emma Modrick, Isabelle Marcus, Simon Kurciski, Isis Kees, Tamara Beitzel Barriquand

IdeaFest 2025

Multiyear time series of current data measured by 2 horizontal SonTek/YSI ADCPs placed mid-depth in the water column at 2 different locations in Humboldt Bay, CA, a shallow, tidally-driven estuary in northern California, were analyzed to determine the contributions of different harmonic frequencies within the bay. Spectral analysis of the time series revealed that the currents are dominated by several tidal harmonics. The 3 dominant frequencies include M2, K1, and O1, but their contribution varies spatially between the two station locations. Additional frequencies in the data indicate overtides, as well as potential interference with topography and the more variable wind-induced …
