Poor Esg: Regressive Effects Of Climate Stewardship, Zohar Goshen, Assaf Hamdani, Alex Raskolnikov May 2026

Poor Esg: Regressive Effects Of Climate Stewardship, Zohar Goshen, Assaf Hamdani, Alex Raskolnikov

Faculty Scholarship

The rise of inequality and global warming are the two ultimate challenges of our time. After decades of congressional failure to address climate change, the private sector has stepped in and adopted a set of environmental, social, and governance (ESG) policies as a market-based solution to a public policy failure. ESG advocates hope that corporate executives would save our planet. Where Congress failed, ESG will succeed.

This Article argues that if ESG-driven climate stewardship ever achieves the scale necessary to have a real impact on global warming, it will hurt the poor. Legislative interventions to combat climate change are nearly …

Mechanisms Of Synergy Between Nanosecond Pulsed Electric Field (Nspef) And Cold Atmospheric Pressure Plasma Discharge (Cap) In Pancreatic Cancer: The Role Of Ros-Mediated Oxidative Stress And Apoptosis, Zobia Minhas

Biomedical Sciences Theses & Dissertations

Pancreatic ductal adenocarcinoma is a highly lethal malignancy characterized by poor prognosis and resistance to conventional therapies. Novel treatment strategies are needed to overcome this resistance. Non-thermal physical modalities, including nanosecond pulsed electric field (nsPEF) and cold atmospheric pressure plasma discharge (CAP), have emerged as potential anticancer approaches; however, the mechanisms underlying their combined effects remain unclear.

This study evaluated whether nsPEF enhances CAP-induced cytotoxicity and investigated the associated molecular mechanisms using the murine Pan02 pancreatic cancer cell line. Cell viability was assessed by WST-1 metabolic activity assays and electric cell–substrate impedance sensing (ECIS). Intracellular reactive oxygen species (ROS) were …

Measurements And Scaling Of Ion Propulsion Impulse During Driven Magnetic Reconnection, Fatima Ebrahimi, Nicholas A. O'Gorman, Kush Maheshwari, Jongsoo Yoo, Alexandre Sainterme, Hantao Ji May 2026

Measurements And Scaling Of Ion Propulsion Impulse During Driven Magnetic Reconnection, Fatima Ebrahimi, Nicholas A. O'Gorman, Kush Maheshwari, Jongsoo Yoo, Alexandre Sainterme, Hantao Ji

Faculty Publications

Impulse scaling during magnetic reconnection, the magnetic energy conversion to kinetic energy, via direct Mach probe measurements in Magnetic Reconnection Experiment is examined. Ion exhaust velocity and impulse scalings with reconnecting magnetic field during the push phase of driven reconnection are presented. The outflows and impulse measurements are compared with global MHD simulations. Both measurements and simulations reveal a favorable scaling, greater than linear, of impulse with reconnecting field. These scaling results establish that magnetic reconnection could be utilized for plasma propulsion.


Raising The Bar: Virginia Constitutional Interpretation Post-Vlaming, The Honorable Lisa M. Lorish, Alec Block, Amy Vanderveer May 2026

Raising The Bar: Virginia Constitutional Interpretation Post-Vlaming, The Honorable Lisa M. Lorish, Alec Block, Amy Vanderveer

University of Richmond Law Review

Across the United States, dozens of state supreme courts choose to interpret their state constitutions as co-extensive, or in “lockstep” with analogous provisions of the Constitution of the United States. Yet since the Supreme Court overruled or changed its interpretation in a number of rights-based cases, state constitutions are receiving new attention. In Virginia, several years before Dobbs sparked this new focus, the Supreme Court of Virginia departed from the Supreme Court of the United States’ interpretation of its Free Exercise Clause analogue and adopted a new standard providing increased protection. In doing so, the Court signaled its willingness to …


Unromanticizing Careers: Redesigning Students’ Beliefs About Success, Camila Bolsoni May 2026

Unromanticizing Careers: Redesigning Students’ Beliefs About Success, Camila Bolsoni

Theses & ETDs

Contemporary higher education culture transmits a set of deeply internalized beliefs about career success that shape students' decisions, constrain their identities, and fuel anxiety, burnout, and rigidity, often without their awareness. This qualitative study examines how undergraduate students at a small public liberal arts college experience and narrate these beliefs through the lens of the Career Illusions Framework (CIF), a seven-dimension conceptual model, built from the ground up for this study, comprising the Straight Path, Identity Lock-In, Status Script, Hustle Loop, Dream Job Illusion, Risk Ceiling, and Quitting Stigma. Using Braun and Clarke's (2006) reflexive thematic analysis alongside systematic spreadsheet-based …

Flipping The Format: A Comparative Analysis Of Pedagogy’S Performance On Comprehension In Introductory Financial Accounting Education, Allison Drozd May 2026

Flipping The Format: A Comparative Analysis Of Pedagogy’S Performance On Comprehension In Introductory Financial Accounting Education, Allison Drozd

Theses/Capstones/Creative Projects

Education is an ever-evolving field, and accounting education is no different. Introductory financial accounting is a required business course at universities that is characterized by high failure rates (Kealey et al., 2005). Evidence suggests that active learning and constructivist approaches improve comprehension of introductory financial accounting concepts as measured by exam performance. All methods studied produced statistically significant positive results on comprehension learning outcomes. Many professors' experiences support the studies' sentiment that active learning is important for teaching course concepts. The evidence reviewed in this thesis supports positive learning outcomes for comprehension of accounting concepts through active learning and constructivist …

Economic Feasibility Of Aquaponics In The Cold-Climate Eastern United States: A Multi-Facility Monte Carlo Analysis, Ryan Nickerson

Master's Theses and Capstones

Most commercial aquaponics facilities fail to achieve profitability, and this challenge is exacerbated in cold climates, where heating, supplemental lighting, and insulated infrastructure inflate operating costs. Existing economic studies are dominated by warm-climate, single-facility cases, offering limited insight into whether cold-climate operators in the eastern United States can achieve profitability through design choices around scale, species selection, and labor optimization. This thesis evaluated the market feasibility of three research facilities (the University of New Hampshire, the University of Maryland, and Ohio State University) and one commercial facility in New Hampshire. The model used a discounted cash flow framework with parameters …


A Data-Driven Assessment Of Coastal Roadway Vulnerability Using Observed Storm Damage Locations, Jack Kearing May 2026

A Data-Driven Assessment Of Coastal Roadway Vulnerability Using Observed Storm Damage Locations, Jack Kearing

Master's Theses and Capstones

Coastal roadways are increasingly vulnerable to storm impacts and sea level rise. One common failure mode during these events is roadway washout, defined in this study as the physical loss or structural failure of roadway segments due to erosion, overtopping, or hydraulic failure. Washout events can disrupt transportation networks, restrict emergency access, and isolate coastal communities, highlighting the need for improved predictive methods that move beyond index-based assessments toward data-driven identification of vulnerable roadways.This study develops a data-driven framework for assessing roadway washout vulnerability using observed damage data and environmental predictors. Machine learning models, including random forest and decision tree …


Home-Level Flood Damage Assessment With Physics-Constrained Deep Learning, James Ojoawo May 2026

Home-Level Flood Damage Assessment With Physics-Constrained Deep Learning, James Ojoawo

Master's Theses and Capstones

Flood damage to residential buildings is commonly estimated using depth-damage functions that treat buildings as interchangeable, ignoring differences in size and layout that influence damage outcomes. In this work, we present a physics-informed neural network that incorporates building characteristics (floor area, bedrooms, bathrooms, stories and garage spaces) and reduces physically implausible predictions in which damage decreases as flood depth rises. The model predicts both the mean and uncertainty of percent damage and is tuned to balance physical consistency and predictive accuracy. Model interpretation shows that building characteristics collectively account for nearly half of predicted damage variability, highlighting the importance of …


Evaluating The Long-Term Fracture Properties Of Asphalt Additives, Kelsey Page May 2026

Evaluating The Long-Term Fracture Properties Of Asphalt Additives, Kelsey Page

Master's Theses and Capstones

Asphalt makes up about 94% of the pavements in the United States which are required to withstand traffic demands and environmental conditions throughout their service life. These pavements are susceptible to aging which leads to increased stiffness and brittleness making them prone to low and intermediate temperature cracking. Currently, Balanced Mix Design (BMD) sets performance targets aiming to mitigate cracking and rutting distresses. It also allows for the use of innovative materials such as additives, which may be used to modify the asphalt binder behavior to meet specific performance targets. Although numerous studies have examined several types of additives, few …

Sensing Rna’S Conformation With A Solid-State Nanopore Device At Various Ph And Temperature, Haopeng Li May 2026

Sensing Rna’S Conformation With A Solid-State Nanopore Device At Various Ph And Temperature, Haopeng Li

Graduate Theses and Dissertations

This study uses solid-state nanopore technology to investigate the stability and dynamics of RNA molecules under thermal stress and pH fluctuations. Two distinct mRNA samples were analyzed: (1) heat shock protein (HSP)-encoding mRNA extracted from Sulfolobus solfataricus P2, a thermophilic archaeon inhabiting extreme environments such as geothermal sulfuric hot springs (pH < 4, temperature range: 65–90°C), and (2) total RNA extracted from White Leghorn chickens, which thrive under standard physiological conditions. ΦX174 virion single-stranded DNA (ssDNA) were included as a comparative reference. Nanopores, fabricated in silicon nitride membranes, were used to electrically characterize the structural properties of individual RNA molecules in solution, close to their native environments. The nanopore membrane separates two chambers containing salt buffer solution, where ionic current is the primary measurement parameter. When a voltage bias is applied across the membrane, ion flow and an ionic current can be measured. Charged RNA molecules driven translocation through the nanopore induces pore resistance changes, resulting in detectable current blockade events. Variations in these events provide insights into RNA secondary structure and conformational dynamics. By systematically altering pH and temperature, this study elucidates the effects of environmental stressors on RNA stability and structural integrity. The findings reveal distinct responses between thermophilic HSP-encoding mRNA and mesophilic RNA, underscoring the adaptive mechanisms of thermophilic RNA under extreme conditions. These results contribute to a better understanding of RNA behavior under stress and establish a foundation for future applications in RNA-based diagnostics and biotechnology development.


Extremum Seeking Compensation And Quantification Of Position Sensor Offset Error In Speed-Controlled Permanent Magnet Synchronous Motors, Tessa Biondo May 2026

Extremum Seeking Compensation And Quantification Of Position Sensor Offset Error In Speed-Controlled Permanent Magnet Synchronous Motors, Tessa Biondo

Masters Theses

Position sensor offset errors present a persistent challenge in speed-controlled permanent magnet synchronous motor drives operating under field-oriented control. Even small, constant offsets in the measured rotor position can reduce torque effectiveness, requiring increased current and voltage demand to maintain the commanded speed and resulting in degraded speed regulation performance across a range of operating conditions. These effects are particularly problematic in speed-controlled systems, where speed loop dynamics cause increased electrical effort and limit overall performance. Many existing detection and compensation approaches are either dependent on the system model, require offline calibration, or are primarily designed for torque-controlled operation. This …

Metabolic And Replicative Constraints On Pathogen Virulence: Isoleucine Catabolism In Shigella And Comparative Tanapoxvirus Replication In Cell Cultures, Benecia Angelica

Masters Theses

Pathogens survive by balancing metabolic demands with environmental challenges that shape their virulence and adaptability. Shigella flexneri, a highly infectious human pathogen responsible for severe diarrheal disease worldwide, utilizes branched-chain amino acid (BCAA) metabolism to withstand stress conditions encountered within the host environment. In this study, we explored the Shigella isoleucine catabolism pathway by knocking out four genes in the S. flexneri isoleucine catabolic pathway (ilvE, fadA, fadD, and acnB) and examining their metabolism and virulence. We found that the ilvE and acnB mutants displayed reduced metabolic activity and smaller plaque size, while the fadD mutant showed decreased invasion. In …
