“About Organs”: A Lutheran Statement About Organ Music From 1597, And Its Historical Context, Markus Rathey

Yale Journal of Music & Religion

The article presents a translation of an important document about organ music, published by the Theology Department at Wittenberg University in 1597. While written in response to an ongoing controversy, the document became the authoritative statement of the Lutheran church about organs and organ music in the seventeenth and eighteenth centuries. The article presents the first complete English translation of the text and it analyzes the historical context of the document.

Tuning The Neighborhood: Purifying People, Places, And Environments In Suburban Kolkata, Sourav Saha

Yale Journal of Music & Religion

In modern science, disciplines such as physics, mechanical and civil engineering, seismology, and acoustics have conceptualized vibration as a quantifiable mechanical phenomenon, measured through the metrics of frequency, amplitude, and resonance. In contrast, scholarship in anthropology, musicology, and sound studies has approached vibration as a socio-historical, cultural, and political phenomenon. This article examines how vibration (spandan) operates as a metaphysical, sensory, and ethico-affective force that mediates relations among people, places, and environments. Focusing on the practice of satsang adhibesan (devotional congregation), the article demonstrates how members of the Deoghar-Satsang community participate in sonic rituals of prayer, silent chanting, meditation, sacred …

Singing About Singing: Images Of Choirs In Aquitanian 'Versaria', Eva Moreda Rodriguez

Yale Journal of Music & Religion

Charles Atkinson and Gunilla Iversen, among others, have noted and discussed the increased presence of terms relating to music, singing and sound in Latin-language liturgical or paraliturgical music of the eleventh and twelfth centuries. The Aquitanian versus and Benedicamus trope repertoires provide a prime example, with words such as cantum, carmen, chorus and others recurring frequently. The recent development of scholarly strands (Emma Dillon, Sarah Kay) that considers how music and text combines (Dillon’s “sound of song”) to shape and put forward discourses that are precisely about the nature of sound, singing and music open up new opportunities to examine …

3d Puzzle Generation Beyond Voxelized Parts, Iris Xia

Computer Science Theses

Burr puzzles are interlocking assemblies whose pieces must be inserted and removed through tightly constrained motions. Designing them is difficult because geometric fit, interlocking behavior, and disassembly order are tightly coupled, while existing computational methods remain largely limited to voxelized or template-based constructions.

This work presents a framework for 3D puzzle generation beyond voxelized parts. The method replaces local mobility heuristics with a certified search over geometry edits. Starting from a topological contact specification, it constructs signed distance fields for individual parts, applies complementary local edits, and validates each candidate using exact geometric checks and a kernel disassembly graph. The …

Node Differentially Private Algorithms For Survivable Networks And Graphs Analysis, Jinghua Sun

Computer Science Theses

This thesis studies two graph algorithmic settings where additional structure gives stronger guarantees than worst-case black-box methods. The paper considers higher order edge connectivity under node differential privacy. We study the minimum k-edge-connected spanning subgraph problem (k-ECSS) and the minimum k-edge-connected component problem (k-ECC). These objectives have large global sensitivity under node privacy, since adding or deleting one vertex and its incident edges can significantly change robust connectivity structure. To address this, we use Propose-Test-Release for locally stable k-ECC instances and a Lipschitz extension framework for k-ECSS, based on bounded-degree complement objectives and the Generalized Exponential Mechanism.

A Just Reimagining Of The Loss & Damage Fund, Sarah Cheung

Master in Public Policy Theses

The Fund for Responding to Loss and Damage (FRLD), established at COP28 in 2023, represents a historic diplomatic breakthrough in multilateral climate finance, yet its design reflects the compromises necessary to secure political agreement rather than a just institutional architecture. This thesis evaluates the FRLD and two prominent reform proposals—the Bridgetown Initiative 3.0 and Esther Duflo's Grand Bargain—against a novel framework that provides a more precise way to evaluate the “justness” of different arrangements. This framework encompasses three dimensions: compensatory, distributive, and procedural justice. A dimension of justice is achieved in a two-fold manner; first, through rhetorical commitments in founding …

Crowding In Private Capital For Climate Adaptation In India, Shreya Bajaj

Master in Public Policy Theses

Reports show that India is highly vulnerable to climate change. Mitigation efforts alone cannot address these risks, and adaptation remains essential. Yet while much of the existing literature documents the adaptation finance gap, it offers less practical guidance on where private capital can realistically be used and what institutional arrangements are needed to make it work. This paper tries to address that gap in the Indian context.

This paper examines three adaptation finance use cases through which private capital could support climate adaptation and resilience in India: parametric disaster risk transfer, pooled municipal finance, and water fund. For each issue, …

The Regionalization Of The North American Auto Industry: A Comparative Analysis Of Automotive And White Goods Trade Under Nafta And The Usmca, 1990-2024, Helen Alexandra Helfgott

Master in Public Policy Theses

This research examines whether the auto-specific provisions introduced under the North American Free Trade Agreement (NAFTA) and the US-Mexico-Canada Agreement (USMCA) have had a measurable regionalizing effect on North American export flows. The USMCA's auto-specific provisions, established in the rules of origin requirements (ROOs), increase regional value content requirements (RVC) while imposing new requirements for labor value content (LVC), steel and aluminum sourcing, and core parts. This research assesses whether these provisions are associated with a distinctive pattern of intra-regional export concentration not present in other sectors.

The study employs a descriptive comparative framework using data from UN Comtrade, spanning …

The Offense-Defense Balance And The Modern System In Ukraine, Daniel Hogestyn

Master in Public Policy Theses

This thesis evaluates whether the Russo Ukrainian war represents a revolution in military affairs (RMA) by testing Stephen Biddle’s "modern system" theory of battlefield outcomes against recent combat operations. Applying Biddle’s formal model to the 2023 Ukrainian offensive in Zaporizhia, the thesis finds that the offensive's failure conforms closely to Biddle’s causal logic, with force employment variables drawn from 20th century combat sufficient to account for the outcome. Biddle's model in military power argues that force employment has explained victory and defeat since World War I, rather than technology or numerical preponderance alone. Many commentators claim that proliferation of small …

Towards Critical Agency: A Case Study Of Japanese Peacebuilding And Development In The Bangsamoro, Hana Soma

Master in Public Policy Theses

Asking “In what ways have anthropological methods been part of Japan's peacebuilding and development interventions in the Bangsamoro?”, this research hopes to make a contribution to the study of anthropology and development and their practical application by exploring the possibilities of the role of an anthropological approach in making sense of modern-day development programs, particularly through the case study of Japan’s peacebuilding-through-development efforts in the Bangsamoro. After outlining the research question as well as the design and methodology used to answer it and an overview of the histories of dispossession and the Japanese relationship to Mindanao, the essay …

A Rarer Earth: The Many States Of Peat In Central Kalimantan, Layna Chen Ms.

Masters of Environmental Design Theses

Peat currently occupies a central place within climate discourse, with Indonesia’s peatlands as a key site of concern since the late twentieth century. Yet this contemporary understanding is historically unstable. Over the last two centuries, what we commonly consider peat has been repeatedly redefined by scientific and bureaucratic institutions. Within popular media, peat has circulated as a low-grade fuel, an infertile swampland, an agricultural soil awaiting rehabilitation, and a hydrological body requiring remediation. Tropical peatland fires, once treated as a scientific improbability, have become a recurring environmental crisis. This history of shifting definitions suggests that ‘peat’ is not a stable …

Stablecoins, Geopolitical Shocks, And Imperfect Arbitrage: A Case Study Of Türkiye, Vincient Arnold

Master in Public Policy Theses

On March 19, 2025, a key Turkish opposition political figure was unexpectedly arrested on what were presumed to be politically motivated charges. In response, the lira depreciated sharply. Meanwhile, Türkiye has a large and active dollar stablecoin market. Using a time series dataset of trade-frequency Tether vs. lira trading, I exploit this natural exogenous geopolitical risk-off event to investigate the response function of stablecoin traders active in Türkiye to this shock. I find that the shock is associated with a large (5.33% ) abnormal depreciation of the lira. Further, I show that the shock is associated with an abnormal widening …

Uneven Ranks: Geographic Deepening Of The All-Volunteer Force, Christine Hogestyn

Master in Public Policy Theses

Who is enlisting in Fiscal Year 2025, and what state-level characteristics are associated with military enlistment rates, service selection, and recruit quality? This study documents the geographic landscape of U.S. military accessions during a period of recruiting recovery, filling a gap in the literature by providing a current, empirical description of who enlists and from where in today’s All-Volunteer Force. Drawing on personnel data from the Department of War, the U.S. Census and Bureau of Labor Statistics estimates, and a federal dataset of military installations, I analyze 203,987 new accessions across the Army, Navy, Air Force, and Marine Corps from …

Silicon Rivalry: Understanding The U.S.-China Ai Competition In Southeast Asia, Daniel Christopher Kent

Master in Public Policy Theses

In the rising global strategic competition between China and the United States, artificial intelligence (AI) has taken on a special significance given its potentially transformative impact upon economics and security. Yet while the dialogue around the “AI race” is typically centered on foundational model capability enhancement, application in security contexts, and chip design and manufacturing, there is much less attention paid to its impact on geopolitics. In particular, AI diplomacy—the work of a state to spread its model of AI governance, evangelize its AI companies, and develop critical AI interdependencies and linkages around the world—is far less studied. Nowhere is …

Global Health Financing Of Diagonal Interventions: Building Resilient And Sustainable Health Systems In Sub-Saharan Africa, Lucy Kim

Master in Public Policy Theses

Background: Global health financing has historically prioritized disease-specific “vertical” programs over broader “horizontal” strengthening of general health systems. Vertical programs in HIV have led to unprecedented reductions in mortality worldwide, but HIV remains a significant public health threat in sub-Saharan Africa, where vertical strategies have long been criticized for creating fragmented health systems. In response, global health strategies have shifted towards combining vertical investments with broader horizontal activities, commonly referred to as “diagonal” programming. While evidence suggests that diagonal programming has the potential to create more resilient and sustainable health systems, evaluating its value for money is challenging due to …

The Digital Rentier State: Saudi Arabia, George Ngoh

Master in Public Policy Theses

As artificial intelligence reshapes Great Power Competition, control over digital infrastructure has become a key measure of global hegemony. In this context, Saudi Arabia is using its Vision 2030 strategy to pivot from traditional hydrocarbon reliance toward diversification into the AI and emerging technology sector, seeking to secure a position of power in an increasingly multipolar world.

This thesis analyzes whether Saudi Arabia’s AI investments signal a transition away from traditional resource rentierism or the creation of a new digital rentier model. Through primary and secondary research, this study argues that the Kingdom is establishing a sustainable pathway toward a …

Beyond The Ban: Chhaupadi Abolition And The Governance Of Menstrual Autonomy In Western Nepal, Nikita Paudel

Master in Public Policy Theses

This thesis examines how two decades of efforts to abolish chhaupadi have shaped the everyday conditions under which women and girls experience menstruation in western Nepal. Chhaupadi, commonly understood as menstrual seclusion, has been addressed through Supreme Court directives, national policy, criminal law, municipal implementation instruments, hut demolition campaigns, public health programming, and rights-based advocacy. Yet the practice has persisted, adapted, and in some cases moved into less visible spaces. Rather than treating this as a simple gap between law and practice, this thesis asks how abolition efforts themselves have become part of the regulatory regime through which menstruation is …

Remaking Buford Highway: Immigration And The Struggle For Walkable Suburbia, Amit Kamma

Harvey M. Applebaum ’59 Award

Constructed according to a car-centric vision typical of American suburbs, one segment of Buford Highway outside Atlanta has become a corridor defined by immigrants who often walk and use public transit. These behaviors conflict with the existing car-focused infrastructure, compelling government actors to make the Highway more multimodal. Progress towards that goal is ongoing and precarious, demonstrating wider systemic challenges in U.S. planning and local governance.

Boundaries Of Inequality: The Political Economy Of Redlining And Modern Mortgage Credit, Kyle Guo

Harvey M. Applebaum ’59 Award

This paper investigates the legacy of historical redlining on contemporary access to mortgage credit across three distinct urban policy environments: Baltimore, Philadelphia, and Manhattan. I find that while historical redlining is associated with a statistically significant negative effect on mortgage approval rates, the magnitude of this direct effect is relatively small. In comparison, applicant race, particularly for Black applicants, is a stronger predictor of mortgage approval rates across cities and models. This study utilizes 1930s Home Owners’ Loan Corporation (HOLC) residential security maps and Home Mortgage Disclosure Act (HMDA) data from 2007 to 2017, and uses ordinary least squares (OLS) …

Objects In The Sunset, Iskander Guetta

Masters of Environmental Design Theses

This research explores everyday design practices in the Maghreb shaped by economic, political, and ecological struggles amid transnational debates on decolonizing design. To do so, it looks at objects in, through and with the sunset. Taking المغرب — the place where the sun sets — as a conceptual lens, Objects in the Sunset illuminates the savoir-faire born from dispossession, scarcity, and epistemic violence. Working across different scales of the built environment — infrastructures, spaces, objects, and materials — it shifts design away from Eurocentric conceptions: from rationalization to resourcefulness, homogeneity to heterogeneity, optimization to adaptation, disposability to repair, and universal …

The Epic Work Of Grief: Loss And Narrative Evolution From Classical Epic To Beloved, Marie Manassee

Yale Divinity School Theses

This thesis examines the evolution of the epic tradition through Virgil’s Aeneid, Dante’s Purgatorio, and Toni Morrison’s Beloved, arguing that grief functions as the central force through which epic form is continually reshaped across historical and cultural contexts. While epic is often associated with heroic conquest, divine destiny, or national foundation, this project contends that the genre is equally structured by acts of loss, mourning, and departure. In the Aeneid, grief becomes the condition of imperial becoming, as Aeneas’s movement toward Rome depends upon the relinquishment of personal attachments and the transformation of loss into historical action. Dante’s Purgatorio inherits …

Ai And The Ethos Of Education: Reflections On Human Learning Past And Present, Melanie Trotochaud

Yale Divinity School Theses

This thesis reflects on contemporary issues of “Artificial Intelligence” (AI), while also bringing into conversation 12th century Christian mystic and polymath Hildegard Von Bingen and 18th century Humanist philosopher Giambattista Vico. Hildegard’s and Vico’s contexts philosophically and historically share similarities to our present moment: reassessing our humanity and learning in times of technological, economic, and social shifts. Holding up their writing to various conversations about our contemporary world helps illuminate the present. Key aspects of the discussion include what constitutes tools or technologies, the agency we have in choosing to use or not to use them, and how we make …

The Course Of Empire Causes Us Much Grief: Imperialism, Slavery, And Genocide In The Theological Education Of Berkeley Divinity School, The Episcopal Seminary At Yale, Alden Fossett

Yale Divinity School Theses

The history of Berkeley Divinity School, the Episcopal seminary at Yale, traverses centuries and thousands of miles between Ireland, Rhode Island, and Connecticut. Abundant institutional narratives concerning Berkeley Divinity School’s origin and development over time rehearse a mythology connecting the Anglo-Irish philosopher and bishop George Berkeley (1685–1753) and the establishment of Berkeley Divinity School in 1854 by Massachusetts-born professor and bishop John Williams (1817–1899). This thesis intervenes in the historiography of Berkeley Divinity School by situating John Williams’s allusion to George Berkeley’s unfulfilled dream to establish a college training Anglican missionaries on the island of Bermuda within a British imperial …

The Macroeconomics Of Intergenerational Mental Health Dynamics, Boaz Abramson, Job Boerma, Diego Daruich, Aleh Tsyvinski

Cowles Foundation Discussion Papers

We develop a quantitative macroeconomic theory of child mental health. The theory is grounded in child psychiatry, formalized in a life-cycle heterogeneous agent model of child development, and disciplined using micro data on mental health of children and parents. Intergenerational transmission of mental illness arises due to both biological factors and parental behavior. Parents experiencing mental illness have negative expectations and lose time due to rumination. As a result, they invest less in their child’s mental health. We use the model to evaluate policies designed to improve child mental health. We show that subsidizing mental health treatment for children generates …

Class Peers As Competitors And Educators: The Consequences Of Rank-Based Academic Rewards, Mark R. Rosenzweig, Bing Xu

Cowles Foundation Discussion Papers

This paper examines the theoretical and empirical consequences of rank-based reward systems in schools in which students’ performance and effort are evaluated relative to their peers. In such environments, classmates act simultaneously as competitors—due to rank-determined rewards—and as educators through peer learning and assistance. Using nationally representative panel survey data from U.S. high schools, combined with administrative information on the location assignments of new refugee student cohorts, we exploit variation in school competition policies and class ability compositions to identify empirically their dual effects on student effort and peer learning. We develop a theoretical tournament model with heterogeneous students who …

Efficient Estimation In Infinite Dimensional Gmm, Jin Seo Cho, Peter C. B. Phillips

Cowles Foundation Discussion Papers

In GMM estimation it is well known that if the number of moment conditions grows with the sample size, GMM asymptotics differ from the standard case with moment size fixed as the sample size tends to infinity. The present work explores infinite dimensional GMM estimation under various conditions on the moment conditions and the weight matrix. Our approach employs a partial sum process formed by the moment conditions to represent high dimensional moments and an invariance principle to capture the infinite dimensional asymptotics as the moment size grows. Next, the GMM weight matrix is assumed to converge to one of …

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 …

Towards A Methodology For Measuring Rental Property Ownership In The United States, Stephanie Kestelman, Rebecca Diamond, John Eric Humphries, Kate Pennington, Winnie Van Dijk, John Voorheis

Cowles Foundation Discussion Papers

Roughly one-third of U.S. households rent their homes, yet measuring who owns rental property is difficult: ownership is frequently obscured by LLCs, partnerships, and other intermediary entities that separate legal from economic control. We develop a method that traces ownership through administrative records—combining deeds and property assessments with the Census Bureau’s Business Register, IRS Schedule K-1 filings, and SEC filings on REITs—to identify ultimate owners and construct property portfolios across the full landlord size distribution. Applying the method to 11 large CBSAs, we find that individual landlords own a large majority of rental units, though their share varies meaningfully across …
