Drone Remote Sensing For Forestry: An Economic Assessment, Micah G. Scudder

University Grant Program Reports

This project addressed a critical knowledge gap in modern forest management: the lack of a standardized, rigorous economic framework to evaluate the true financial viability of Unmanned Aerial Systems (UAS/drones). Supported by this seed grant, an economic evaluation protocol rooted in engineering economics was developed and translated into a functional financial template tool. When external structural funding changes at a partner flight agency restricted upfront fixed-wing hardware access, the research design was pivoted from a single-site case study at Lubrecht Experimental Forest to a multi-project empirical validation. The framework was applied across nine distinct drone remote sensing projects managed by …

Aligning Tenure With Institutional Values: Supporting And Rewarding Engaged Scholarship In College Tenure Policies, Sian Bareket, Alexander R. Barron, Abigail O’Meara, Charavee Basnet Chettri

Environmental Science and Policy: Faculty Publications

Scholars have described the current era as a polycrisis, with climate change overlapping and interacting with other social justice and environmental challenges. While the expertise and capacity housed in academia has tremendous potential to help society face these threats, scholars and others have long critiqued academia as too isolated from the practical problems of society and front-line communities. While engaged scholarship (ES) connects academia and real-world problems, tenure policies are usually designed to primarily reward “traditional” scholarship focused on journal articles and academic books. This study sought to investigate the contrast between higher education institutions’ publicly shared values aligned with …

Isolating Human Monocytes And Characterizing Human Macrophage Polarization Through Flow Cytometry And Morphological Analysis, Arthur Peter Klujian

Biomedical Engineering

Peripheral Artery Occlusive Disease (PAOD) is a cardiovascular disease that affects more than 200 million people. It is characterized by atherosclerosis, a biologic process where peripheral arteries are restricted due to a buildup in cholesterol and fats. This eventually leads to ischemia, developing complications such as chronic inflammation and possible limb amputation. The current standard of care for patients includes surgical revascularization and exercise therapy. These treatment strategies have had limited success with alleviating symptoms and restoring perfusion, however, many patients still experience ischemia and do not fully restore blood flow. Further exploration in pursuit of treating these shortcomings led …

Scientific Uncertainty As Political Aggression: A Manifesto For Those Who Value Science And Want To Save It From State And Corporate Control, Stephen Demeo

Publications and Research

A manifesto is an opportunity to publicly express strongly held beliefs about a topic that is personally important to an author. It is analytical as it is creative. “Scientific Uncertainty as Political Aggression” is a manifesto that intersects science and politics. It urges those interested in science to examine two different but related topics: scientific uncertainty in measurement—what it is, how it is determined, why it’s important— and the magnification of uncertainty through legal and linguistic tactics used by right-wing politicians and politically supported corporations.

For some time now, the Republican Establishment has cast excessive doubt on scientific findings through …

Don’T Let Us Down: A Phenomenological Study Of African American Employees’ Perceptions Regarding The Benefits Of Professional Development In Student Affairs, Courtney Nicole Demings

Electronic Theses and Dissertations

The experiences of student affairs professionals are critical to the success of higher education, allowing for a concentrated exploration of African American student affairs professionals who are often employed in 2-year U.S. community colleges. The general problem was that African Americans may leave student affairs in community colleges if they do not perceive supervisory support for professional development and, in turn, career advancement. The purpose of this dissertation was to understand and interpret their lived experiences, illuminate the barriers to their career advancement, and discuss the impact of supervisory support. As such, this action research employed qualitative research through the …

Harkness Seminars In The Humanities, Sarah S. Novlan

Electronic Theses and Dissertations

This participatory action research study explored the effects of Harkness seminars on students’ cognitive, affective, and metacognitive learning in secondary humanities classes. Educators need an effective, flexible, and adaptive method to promote student learning beyond superficial content acquisition. With the decoupling of virtue formation from knowledge acquisition, knowledge gaps from COVID-19 lockdowns, and the rise of artificial intelligence in student plagiarism, a proven method to address all aspects of student formation is needed. Using a participatory action research framework for this qualitative study, conducted at an independent K–12 school site in Texas, the researcher interviewed six secondary humanities teachers over …

Mechanical and Materials Engineering Faculty Publications and Presentations

Scientific assessments play a critical role in synthesizing evidence to support evidence-based decision-making in many sectors and topics. For climate change, large-scale assessments like the Intergovernmental Panel on Climate Change (IPCC) and the United States (U.S.) National Climate Assessment (NCA) reports help many different users—from national government to local governments, Indigenous Peoples and communities, the private sector, the social sector, and the scientific community itself—navigate the complex field of climate risks, impacts, and integrated solutions. While co-creation with users is essential to developing actionable assessments, this paper lays the groundwork for future processes by identifying many advancing and emerging areas …

Data-Driven Analysis For Managing Causes Of Disputes In Nuclear Power Plant Construction Projects, Mahmoud S. Mansour, Islam H. El-Adaway

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Nuclear energy remains a key element of the energy mix in the United States (US) and other parts of the world, with renewed and increased interest in recent years, driven by rising energy demand across various sectors. This is due to its capabilities of generating a vast amount of reliable and carbon-free electricity, which are crucial advantages as compared to other energy sources. However, nuclear power plant (NPP) projects involve unique risks and complexities that have long hindered their progress and shaped dispute dynamics differently from other construction sectors. Despite extensive research on construction disputes, there is a lack of …

Complex Adaptive Resilience And Asymmetrical Balancing: Russia And The 2022 Sanctions Regime, Renny Puspitarini, Sartika Soesilowati, Kacung Marijan, Ahmad Iskandar Rahmansyah

Journal of Strategic Security

The 2022 Russian invasion of Ukraine prompted unprecedented Western sanctions, which amounted to more than 23,000 sanctions during 2022-2024. However, these sanctions failed to fulfill their designated objective of influencing the end of the Russia-Ukraine War. Russian responses to progressively augmented sanctions have sparked debates surrounding microeconomic sovereignty, macroeconomic adaptability, and, foremost, resilience. The article’s findings reveal that while sanctions have not brought the Russian Federation to acquiesce, they have catalyzed a structural, politically induced policy shift into a Complex Adaptive Resilience (CAR) framework. Russia's ability to build resilience against sanctions has been manifested structurally in its strategy to reinforce …

Structural Dependency: Nato, Defense Industry Politics, And Europe’S Stagnation, Diane M. Zorri

Journal of Strategic Security

Europe’s defense industrial base (DIB) weaknesses are commonly attributed to underinvestment, fragmented policies, or a lack of European cohesiveness. This article advances an alternative explanation: European defense industrial dependency has emerged through institutionalized alliance structures that systematically privileged US capabilities and incentives, becoming self-reinforcing and difficult for European actors to exit, even as their strategic preferences evolved. Drawing on dependency theory, path dependence, and theories of alliance politics, this article argues that transatlantic security arrangements established during the early Cold War, most notably NATO’s integrated command structures, defense procurement norms, and interoperability requirements, have generated long-lasting asymmetries in production, technology, …

Reinterpreting The Grand Ethiopian Renaissance Dam Dispute In The Nile Basin Through The Game Theories Of Attrition And Bargaining, Olileanya Amuche Ezugwu, Felix C. Chidozie, Adeola A. Adebajo

Journal of Strategic Security

Why have more than a decade of negotiations, mediation efforts, and diplomatic interventions failed to produce a binding agreement on the Grand Ethiopian Renaissance Dam (GERD)? This article examines the hydro-politics of the Nile Basin through the lens of game theory, focusing on how bargaining behavior, strategic persistence, and competing perceptions of gains and losses shape state interactions. Drawing on the game of attrition and the bargaining game, the study analyzes the evolving strategies of Ethiopia, Egypt, and Sudan in the context of dam construction, filling, and operation. Rather than viewing the dispute solely as a contest over water allocation, …

Borders And Bids: Assessing How Competition In Transportation Projects Is Shaped By The Presence Of Out-Of-State Contractors, Mariam Elazhary, Islam H. El-Adaway

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Competitive bidding in transportation construction is vital for securing better value for money and higher-quality proposals. Prior research has attempted to encourage more competition by proposing novel delivery methods, contractual incentives, or alternative bidder profiles. However, one viable bidder profile, which has received limited attention in the literature, is to encourage cross-border participation to expand the pool of qualified firms and thereby increase competition. While, in theory, this may improve economic efficiency, the inclusion of more out-of-state contractors (OSCs) is not costless. The goal of this paper is to assess whether participation by OSCs is associated with strengthening competition in …

Allyship And Affect: Qualitative Investigations Into Social Transformation, Michael Lucinda Jane Greer

Dissertations, Theses, and Capstone Projects

Allies have faced several critiques in feminist philosophy. Some have argued that they lack the requisite political interests to be motivated to dismantle the social structures from which they stand to benefit. Others have argued that the epistemic limitations resulting from their social privilege are insurmountable. Yet others have argued that allyship is too individualistic a concept, preferring a more collectivist concept like solidarity. However, there remain privileged individuals who understand themselves as complicit in perpetuating oppressive forms of life, and who wish to transform themselves and work in coalition across difference to dismantle structural oppression. How ought these individuals …

Alzheimer’S Disease And Related Dementias Risk Profiles And Health Literacy Among South Asian Seniors, Sandra A. Kennedy

Dissertations, Theses, and Capstone Projects

Alzheimer’s Disease and Related Dementias (ADRD) pose significant health challenges globally, with South Asian seniors in the United States facing elevated risks due to high rates of cardiovascular disease, diabetes, and limited health literacy. This study assessed dementia literacy and the prevalence of cardiovascular, psychosocial, and lifestyle risk factors among South Asian seniors in New York City, utilizing community-based participatory research (CBPR) principles in collaboration with India Home, a community-based organization. Fifty-six (N=56) South Asian seniors aged 55 and older (M = 69.05, SD = 6.36), primarily of Indian or Bangladeshi origin, participated in the study. Data collection involved a …

The Cranial Nerves And Electrical Stimulation, Devin K. P. Adair

Dissertations, Theses, and Capstone Projects

Cranial nerves provide afferent pathways that enable bottom-up modulation of central autonomic and cognitive neural pathways. Because these pathways project to brainstem nuclei such as the nucleus tractus solitarius and engage neuromodulatory systems, including the locus coeruleus, electrical stimulation offers a mechanistically grounded approach to influencing brain function. This thesis tested whether active transcutaneous auricular vagus nerve stimulation (taVNS) produces physiological responses indicative of parasympathetic engagement, defined as decreases in heart rate, increases in heart rate variability, and decreases in respiration relative to a dose-matched earlobe control condition. Using cardiac and respiratory measures as physiological markers, taVNS at the tragus …

Vibe Diggers: The Sampling Of Brazilian Music In Hip-Hop, Romulo De Carvalho Moraes Barbosa

Dissertations, Theses, and Capstone Projects

This dissertation investigates the trend of musical borrowings of 1970s MPB (música popular brasileira) by contemporary American hip-hop producers, especially in terms of what they have called a “Brazilian vibe.” A lot has been said about sampling already from legal, sociological, and historical points of view, but less has been said about its aesthetic procedures, and even less about the wider implications of a tendency for using transnational sources. In the case of MPB, hip-hop artists seem to understand the music they sample through an often vague, intuitive representation, which fuses qualities of those recordings with an intersubjective mood, a …

Potential Energy Landscape Formalism For Quantum Liquids, Yang Zhou

Dissertations, Theses, and Capstone Projects

Atomic delocalization due to nuclear quantum effects (NQE) remains poorly understood in low-temperature liquids near the glass state and during vitrification. Many liquids can be described accurately by treating their nuclei as classical particles, but this approximation fails for light elements such as He and H₂, small hydrogen-containing molecules such as water, and systems in which zero-point motion or isotope-substitution effects are important. Developing a general thermodynamic and statistical-mechanical description of such liquids has been challenging. This dissertation extends the potential energy landscape (PEL) formalism, originally developed for classical liquids and glasses, to liquids that obey quantum mechanics and exhibit …

Object (Im)Permanence: Toward A Hauntology Of The Violin, Pala Garcia

Dissertations, Theses, and Capstone Projects

Object (Im)permanence goes looking for the violin’s ontological uncertainties, its persistent historical specters, and its relation to things not fully present, no longer, or yet to come. Drawing on the history of the author’s own instrument as an inherited object, this study explores the violin’s strangest affordances: its capacity to hold a psychic charge, sustain absent presence, remotely activate somatic memory, and invite reciprocal relationality. Adapting the Derridean concept of “hauntology” as a framing for the violin’s spectral vitality, Object (Im)permanence imagines how a hauntology of the violin can account for its ontological uncertainties, logic of absent presence, and persistent …

Reimagining Folk Songs: A Bridge Between Tradition And Innovation In Georgy Sviridov’S Music, Polina Nazaykinskaya

Dissertations, Theses, and Capstone Projects

Georgy Sviridov (1915–1998), one of the most prominent Soviet composers of his generation, remains largely underrepresented in Western performance and scholarship. This dissertation examines the compositional language of Sviridov’s Kursk Songs (1964) through direct comparison with the seven folk songs published in Anna Rudneva’s 1957 collection Kurskie pesni that served as the work’s source material. The study addresses a central paradox of Sviridov’s musical language: how remarkably economical, predominantly diatonic materials can produce powerful and highly individual expressive results.

The analysis considers how Sviridov preserves essential characteristics of the folk sources while transforming their harmony, rhythm, form, texture, orchestration, and …

Behind The Score: The Influence Of Neighborhood Policy Contexts On New York Regents Exam Performance Across New York City Public High Schools, Philip J. Kovacevic

Dissertations, Theses, and Capstone Projects

This study used a two-level hierarchical linear model (HLM) to test whether New York City neighborhood zoning and land-use characteristics independently predict school-level performance on the New York State Regents Examinations, after controlling for school demographic and organizational characteristics, and Regents mean scores, both drawn from the NYC DOE's Regents Exam Results file (NYC Public Schools InfoHub, 2024). Using NYC Primary Land Use Tax Lot Output (PLUTO) 2025 data, a Neighborhood Educational Quality (NEQ) index was built for each of the city’s 42 community districts by combining the commercial floor area ratio (CommFAR) and the proportion of lots zoned residential …

A Study Of Bengali Grapheme-To-Phoneme Conversion, Arundhati Sengupta

Dissertations, Theses, and Capstone Projects

Grapheme-to-phoneme (G2P) conversion is a foundational component of speech technology, yet the languages for which it has been carefully studied remain a small fraction of the world's languages. Bengali is spoken by over 230 million people, making it one of the world's most widely used languages, but it remains comparatively understudied in natural language processing, and G2P for Bengali in particular has received less attention.

In this dissertation, we use neural architecture comparison, error analysis, and explicit correction techniques to identify and address the sources of G2P error in Bengali. First, we train and compare four neural G2P architectures, including …

Assessing The Relationship Between Housing Provision And State Legitimacy Through The Vision 2030 Plan In Saudi Arabia, Shovan Bala

Dissertations, Theses, and Capstone Projects

Scholars have long evaluated the politicization of housing by examining the relationship between housing provision and legitimacy across democratic and authoritarian states. This thesis contributes to the scholarship on housing provision and state legitimacy by examining the Saudi state’s recent housing development efforts, and its role in shaping citizens’ housing aspirations and informing their understanding of housing as a state responsibility. Using the Vision 2030 Plan’s Sakani and Ejar initiatives, I examine the nexus between Saudi government’s housing development efforts and provision of financial incentives and citizens’ perceived reliance on the state for housing. I evaluate these housing initiatives through …

Cavity Optomechanics Via Mechanically Induced Coupling Of Optical Modes, Satyam S. Jha

Dissertations, Theses, and Capstone Projects

This thesis introduces a transverse, symmetry-breaking mode of optomechanical coupling that departs from the conventional dispersive and dissipative interactions, taking its motivating platform from whispering-gallery-mode (WGM) resonators, where a mechanical displacement lifts the near-degeneracy of azimuthal mode pairs and couples them. After reviewing the standard optomechanical model and the sideband-cooling phenomenology it underlies, we derive the Hamiltonian for the transverse-coupling system and first study its Hamiltonian dynamics, without drive or dissipation. Recast in terms of Schwinger pseudospin operators, the model exhibits a Hamiltonian Hopf bifurcation separating stable and unstable dynamical regimes. In the stable regime, the mechanical nonlinearity permits controlled …

Curated Spaces: Cognition By Design, Sydney Harvey

Dissertations, Theses, and Capstone Projects

“Curated Spaces: Cognition by Design” is a dissertation that considers the connection between designed spaces and cognition. This work combines philosophy of mind and aesthetics. The dissertation introduces the term “Curated Cognition”, which builds on the concept of situated cognition ( Brooks, 1991; Odling-Smee, Laland, and Feldman,  2003;  Sterelny, 2010; Krueger, 2015; Colombetti, 2020 ). The dissertation argues that the environment is essential to cognition, and all environments are curated; therefore, the way we think, feel, and act is curated as well. Some non-human animals may inhabit worlds that are not curated. For example, an octopus may find shelter in …

Modeling Large Language Model Cognition, Eleni Angelou

Dissertations, Theses, and Capstone Projects

This project builds three core directions in a philosophy of cognitive science for large language models (LLMs): 1) interpreting LLM behavior, 2) analyzing the system in terms of Marr’s three levels, and 3) mapping the correspondence between behavioral outputs and the internals of the system. It consists of the following three chapters accordingly:

Dennettian Stances and Large Language Models

The aim of this chapter is to argue that there are convincing grounds for applying Dennett’s framework of stances to LLMs against worries that doing so produces “counterfeit people”. After introducing the intentional and design stances, I take sycophancy as a …
