Evolution As Spatial Projection, Charles H. Smith, Ngoc Nguyen

Faculty/Staff Personal Papers

A theory combining explanations for the nature of three-dimensional systems and evolutionary processes is advanced, set to a geometric simulation, and then discussed in the context of several empirical studies bearing on its validity. The concept “evolution” is first discussed, then related to Baruch de Spinoza’s ideas on natural philosophy, including his concept of the conatus. These ideas are then extended by posing the possible existence of a general form of natural systems subsystemization leading to the extended space condition. A geometrical/topological simulation study projecting spatial relations among subsystem structures interpretable through entropy maximization and multidimensional scaling methods is presented, …

Antitrust, Vampires And Bloody Acquisitions, Theodosia Stavroulaki

Fordham Law Review

Private equity has rapidly seized control of large swaths of the U.S. healthcare system. This Essay argues that its takeover is not a story of efficiency or innovation but one of extraction. Drawing on a substantial body of research, it shows that private equity acquisitions are associated with rising healthcare costs, inferior care, reduced access to essential services, and deteriorating working conditions for physicians and nurses—harms that fall most heavily on marginalized communities.

These outcomes are not accidental. They stem from the private equity business model, which relies on leveraged buyouts, aggressive cost cutting, and roll-up strategies designed to generate …

5 Bfts Association Newsletter No. 34 - Spring 2026, Jenifer A. Harding

Newsletters

After a very dreich winter (dreich is a Scottish word meaning in this context, a period of wet dismal weather which just about sums up January and February 2026), March has brought ‘lions and lambs’ – it has been very cold and very hot, very wet and very dry, very sunny or less so and Storm Dave brought high winds and snow to parts of the UK. Those of us who live in the UK love talking about the weather – and we have had much to discuss during March and early April!

Spring brings us beautiful flowers; the daffodils …

Life, Liberty, And The Pursuit Of A Sustainable Catch: Using Maine's Right To Food To Encourage Sustainability In The Lobster Industry, Emma Rodgers

William & Mary Environmental Law and Policy Review

Every year, millions of sharks, turtles, whales, and other marine life are swept up in fishing gear never meant for them. This collateral damage, known as by-catch, is a persistent and deadly problem in the fishing industry. The World Wildlife Fund (WWF) estimates that around 38 million tonnes of global marine catch each year—40% of all fish pulled from the ocean—is unintended by-catch. Unfortunately, the WWF approximation of annual by-catch likely underestimates the proper amount of by-catch because their estimation includes little information on large marine animals, such as turtles and cetaceans which are also caught in the by-catch process. …

The Resilience Of What, Exactly, To What, Exactly, Along The Coast? Adapting To More Than Just Human Migration, Robin Kundis Craig

William & Mary Environmental Law and Policy Review

The world’s coastlines are changing as a result of climate change and ocean acidification, creating drivers of human adaptation efforts— efforts that may increasingly include migration inland. Rising sea levels tend to get most of the attention as coastal migration drivers, because they represent the force most likely to physically push residents away from the coast through inundation, coastal erosion, and/or destruction of coastal water supplies.

However, climate change and ocean acidification are also changing the world’s coasts ecologically, and these ecological changes also drive coastal adaptation, testing the adaptative capacity and ecological resilience of coastal communities. This Article examines …

The Federal Trust Responsibility In An Era Of Coastal Retreat: Climate Relocation, Fiduciary Governance, And The Future Of Tribal Self-Determination, Samuel Kohn

William & Mary Environmental Law and Policy Review

Climate-driven displacement is no longer a speculative concern for Indian Country. Across our country, from Alaska, to the Gulf Coast, and the Pacific Northwest, Tribal communities confront accelerating erosion, sea-level rise, permafrost thaw, and chronic flooding that threaten not just individual structures, but the territorial foundations of Tribal sovereignty itself. Schools, clinics, water systems, housing, and transportation networks are increasingly exposed to conditions that render continued habitation unsafe or impossible. These impacts do not present as isolated disasters; they manifest as cumulative, slow-onset processes that erode the capacity of Tribal governments to govern in place.

This Symposium Essay advances the …

Storycomposerai: Supporting Human-Ai Story Co-Creation Through Decomposition And Linking, Shuo Niu, Dylan Clements, Marina Margalit Nemanov, Hyungsin Kim

Computer Science

GenAI's ability to produce text and images is increasingly incorporated into human-AI co-creation tasks such as storytelling and video editing. However, integrating GenAI into these tasks requires enabling users to retain control over editing individual story elements while ensuring that generated visuals remain coherent with the storyline and consistent across multiple AI-generated outputs. This work examines a paradigm of creative decomposition and linking, which allows creators to clearly communicate creative intent by prompting GenAI to tailor specific story elements, such as storylines, personas, locations, and scenes, while maintaining coherence among them. We implement and evaluate StoryComposerAI, a system that exemplifies …

The Last Boat: How American And Polish Domestic And Foreign Policies Shaped The Polish Jewish Emigration Experience, 1933–1939, Jesse Spadaccini

History & Classics Undergraduate Theses

The interwar period from 1918 to 1939 saw Poland and the United States contend with major international and domestic questions regarding Jewish emigration. In a matter of twenty years, Polish policy developed from protecting its Jewish minority to actively persecuting it in political, economic, and social spheres with radical antisemitism. In the United States, immigration was limited post-1924 because of a nationality-based quota system introduced by the Immigration Act of 1924. Despite diplomats arguing for increased numbers, American officials’ position remained strong on limiting immigration, continuing unchanged as an understanding of Polish-Jewish plight became clear in the 1930s. The Polish …

Great Commission Research Journal

Despite growing concern about youth disengagement from Christianity and the Christian church (Pew Research Center, 2025), strategies specifically tailored to engage Asian American youth remain under-researched. Drawing from interviews with 16 senior pastors and youth leaders across North America, this paper presents key findings on current ministry practices, with implications of emerging approaches to foster deeper youth engagement in Asian American church contexts.

Geopolitical Myths And Symbols In Independent Kazakhstan: The Case Of The Head Of Kenesary Khan, Assem Maralova

Dartmouth College Master’s Theses

This thesis examines the political myth surrounding the severed head of Kenesary Khan, the last khan of the Kazakh Khanate, and its significance in contemporary Kazakhstan. Focusing on historiographical debates, media narratives, and collective memory, the study analyzes how the unresolved fate of Kenesary Khan’s head functions as a symbolic site of post-colonial identity formation. Drawing on archival sources, scholarly literature, and cultural media, the research demonstrates that the myth operates as a tool for negotiating sovereignty, historical justice, and national memory in Kazakhstan’s nation-building process.

Numerical Study Of Nutrient Mixing In Trabecular Bone In Microgravity, Disuse And Normogravity, Sagar Gharti

Doctoral Dissertations and Master's Theses

Mechanical loading is known to regulate bone remodeling by driving interstitial fluid flow which stimulates cells and drives nutrient transport within the trabecular network. In microgravity, the absence of mechanical stimulation or loading suppresses convective flow processes, causing diffusion-driven nutrient mixing and renewal, and accelerated bone loss. This thesis investigates how oscillation frequency and trabecular bone density jointly control nutrient mixing and wall shear stress within trabecular cavities.

A computational fluid dynamics (CFD) framework is developed in STAR-CCM+ using a soft-cap oscillation model that mimics cyclic compression. Three idealized trabecular morphologies are simulated across different frequencies to represent microgravity or …

Determinants Of Future Suas Adoption: An Empirical Analysis Of Organizational And Behavioral Factors Within The Commercial Aviation Maintenance Enterprise, Jordan Baus

Doctoral Dissertations and Master's Theses

The adoption of small Uncrewed Aircraft Systems (sUAS) represents a significant technological shift within the commercial aviation maintenance enterprise, offering the potential to improve inspection accuracy, enhance operational efficiency, and reduce maintenance-related risk.

Numerical Investigation Of Rotor-Gust Acoustic Interactions Using The Overflow Cfd Solver, Jordan Mills

Doctoral Dissertations and Master's Theses

The rapid expansion of Urban Air Mobility (UAM) necessitates high-fidelity modeling to predict and mitigate the noise signatures of electric vertical take-off and landing (eVTOL) aircraft within dense urban landscapes. A critical unknown in community-noise certification is the aeroacoustic response of rotors to unsteady inflow conditions. This research addresses this gap by investigating the aerodynamic and acoustic behavior of a representative rotor subjected to time-harmonic inflow disturbances. By establishing a robust numerical framework, this thesis quantifies the relationship between periodic atmospheric gusts and their impact on rotor performance, unsteady blade loading, and subsequent sound radiation. The research consists of a …

Doctoral Dissertations and Master's Theses

As Multi-Agent Systems (MASs) become increasingly involved in every aspect of everyday life the need to maintain reliability and resilience within these systems grows. However, in equal measure bad actors wishing to maliciously control or alter these systems are growing in both scale and capability. Thus, there is a present need for control schemes and agent behaviors that provide security against these threats while also avoiding large degradation in system performance as a tradeoff. Current research has covered a wide breadth of avenues and strategies that provide measurable resilience to faulted agents. However, these strategies often require group consensus, specialized …

Scenarioxp: A Complete Scenario-Based Testing Framework For The Exploration And Exploitation Of Autonomous Vehicle Validation Scenarios, Quentin Goss

Doctoral Dissertations and Master's Theses

Today is an age of exciting emerging technology where cutting-edge research in autonomous vehicles (AVs) reduces the active human participation in driving and extends awareness beyond human limitations of perception and reaction, improving driving safety and quality of the user experience as a result. The ever-increasing complexity of these autonomous systems poses many challenges towards the validation and verification (V\&V) of these complex systems under time and resource constraints, as the use of artificial intelligence and also the intricacy of the operating environment means that these systems are also black-box and non-deterministic. Scenario-based V\&V testing of such systems, which involves …

Ellie - Exteroceptive Light Locomotion In Eukaryote-Fungi, Brandon Etwarroo

Doctoral Dissertations and Master's Theses

Over the past decade, fungal research and its technological applications have expanded across multiple disciplines, including the emerging field of biohybrid systems. This thesis develops and evaluates a wireless, untethered mobile robot controlled by the action potential-like activity generated by Pleurotus ostreatus sporocarps under red, green, and blue optical stimulation. Light is applied to the sporocarps, the resulting electrical responses are recorded, and these signals are transmitted wirelessly to actuate the mobile robot. Both the action potential-like activity patterns and the robot’s movement trajectories were analyzed. The results demonstrate that wireless robotic control mediated by fungal electrophysiology is feasible. Overall, …

Effect Of Nozzle Pressure Ratio On Thrust And Flow Behavior In A Supersonic De Laval Nozzle, Esha Jain

Doctoral Dissertations and Master's Theses

Supersonic nozzles operate across a range of flow regimes. While an ideally expanded condition yields optimal thrust, practical propulsion systems rarely operate at this design point due to variations in altitude and engine operating conditions. As a result, nozzles frequently operate in off-design conditions. In overexpanded regime, where the exit pressure is lower than the ambient pressure, shock-induced separation may occur within the divergent section of the nozzle, potentially degrading nozzle performance. Understanding the aerodynamic behavior of nozzles operating under off-design conditions is therefore important for improving propulsion system performance and stability. In particular, direct thrust measurements provide a key …

Specifically, this …

Study Of Output And Behavior Of Llms Using Confidence Framing In Prompt Engineering, Micah Parrilla

Doctoral Dissertations and Master's Theses

While prompt engineering is pivotal for shaping Large Language Model (LLM) outputs, the impact of confidence framing on behavioral calibration remains underexplored. This study investigates the ways in which psychological framing, utilizing techniques such as capability praise, role amplification, and doubt induction, affects linguistic tone, objective accuracy, and internal calibration. A 1,080-trial experimental matrix evaluated six diverse models across factual, logical, coding, and cyber security domains. Analysis using the Kruskal-Wallis H-test revealed highly significant behavioral shifts across all measured dimensions, providing conclusive evidence that the applied frames exert a substantial influence on model performance.

The findings identify a distinct cognitive …

Roadside barriers such as guardrails are fundamental to roadway safety, providing a critical last line of defense in preventing vehicles from leaving the roadway and impacting potential hazards. As vehicles are ever changing, it is necessary for guardrail design to adapt in response. Many contemporary vehicles such as sport utility vehicles and light trucks have higher centers of gravity than previous years, while electric vehicles have increased weight. Having sufficient guardrail height is essential to ensure proper engagement with vehicles to prevent loss of containment during impact.

The purpose of this study is to evaluate the performance of current Florida …

Safety-Aware Trajectory Generation For Increased Autonomy In Advanced Air Mobility, Edison Alberto Martinez Samaniego

Doctoral Dissertations and Master's Theses

Advanced Air Mobility (AAM) envisions highly automated aircraft that will enable short and medium range transportation. Unlike conventional aviation, these vehicles are expected to operate closer to populated areas and with increased levels of autonomy, making safe operation under abnormal or degraded conditions a critical requirement. Failures or performance degradation can reduce the maneuvering capability of an aircraft, causing trajectories planned under nominal conditions to become dynamically unfeasible.

This thesis presents a trajectory generation and replanning framework designed to maintain safe and feasible flight under reduced flight envelope conditions for a lift+cruise eVTOL aircraft. A unified control architecture based on …

Quantification Of The Depth-Of-Field In A Self-Aligned Focusing Schlieren System, Alexander Ephraim

Doctoral Dissertations and Master's Theses

This thesis investigates self-aligned focusing schlieren (SAFS) as a step toward future volumetric and quantitative measurements of three-dimensional compressible flows. Conventional schlieren imaging provides valuable visualization of density gradients, but it records only a line-of-sight projection and therefore does not directly resolve the spatial distribution of structures through the depth of the flowfield. SAFS addresses part of this limitation by introducing depth sensitivity, but its depth response has not been well characterized quantitatively. To help lay the foundation for future volumetric and quantitative SAFS methods, this work addresses two related problems. First, calibrated quantitative schlieren imaging is applied to an …

Adaptive Methods Of Resident Space Object Identification For Space Situational Awareness, Evan Pavetto-Stewart

Doctoral Dissertations and Master's Theses

One of the fundamental tenets of Space Situational Awareness (SSA) is the detection and sub sequent identification of Resident Space Objects (RSOs) within unresolved optical space imagery. This function is vital to the documentation and tracking of RSOs in their respective operational orbits, knowledge that is necessary for collision avoidance efforts and Space Domain Awareness (SDA) applications. In previous work, development was begun on a MATLAB program called RSOID to fulfill this purpose by accepting a collection (or ’collect’) of unresolved imagery and outputting a sequence of RSO locations (called a ’tracklet’) that can be used to determine the RSO’s …
