Relativistic And Recoil Corrections To Light-Fermion Vacuum Polarization For Bound Systems Of Spin-0, Spin-1=2, And Spin-1 Particles, Gregory S. Adkins, Ulrich D. Jentschura

Physics Faculty Research & Creative Works

In bound systems whose constituent particles are heavier than the electron, the dominant radiative correction to energy levels is given by light-fermion (electronic) vacuum polarization. In consequence, relativistic and recoil corrections to the one-loop vacuum-polarization correction are phenomenologically relevant. Here, we generalize the treatment, previously accomplished for systems with orbiting muons, to bound systems of constituents with more general spins: spin-0, spin-1=2, and spin-1. We discuss the application of our more general expressions to various systems of interest, including spinless systems (pionium), muonic hydrogen and deuterium, and devote special attention to the excited non-S states of deuteronium, the bound system …

Psychological Science Faculty Research & Creative Works

Background: Our perception of the auditory world allows us to enjoy the richness of music and communicate effectively with others. These everyday processes are disrupted in conditions such as amusia, an inability to perceive music accurately, and misophonia, an intense emotional reaction to common sounds produced by others. We describe a case of acquired, concurrent amusia and misophonia in a 21-year-old right-handed woman following a right posterior insula, posterior temporal, supramarginal cortex, and sensory cortex resection for the treatment of drug-resistant epilepsy. Methods: The patient participated in interviews between 4–8 months post-resection. She completed an extensive testing battery designed to …

Character Judgements Of Rap Music Fans, Kaila C. Putter, Dan J. Miller, Amy M. Belfi, James Rees, Amanda E. Krause

Psychological Science Faculty Research & Creative Works

Extending Fischoff, we used vignettes to examine people's perceptions of a hypothetical rap fan accused of murder. Study 1 (N = 300) used a 2 (murder accusation) x 2 (inclusion of rap lyrics) x 2 (fan gender) experiment, asking participants to judge how capable of murder and sexually aggressive they found the fan. The presentation of lyrics and murder accusation were associated with the fan being more capable of murder, while rap lyrics and participants' rap attitudes were associated with the fan being more sexually aggressive. Thematic analysis revealed that, in conditions containing both the lyrics and the murder accusation, …

A Method For Determining A True National Statistical Distribution Of Building Element U-Values And Its Application To A Dataset Underpinning A Building Stock Energy Model, C. Ahern, Bernard Enright, A. Griffin, B. Norton

Research Outputs: 2025-Present

The presence of default U-values in Energy Performance Certificate (EPC) databases disrupts the natural variability in measured U-value distributions. Default values, often used by assessors when empirical data is unavailable, introduce deterministic artefacts into datasets, creating artificial peaks that obscure underlying statistical patterns. This study examines the impact of these default values and identifies appropriate statistical models – Lognormal, Gamma and Normal – for measured U-values in Ireland’s national EPC dataset, comprising 463,582 dwellings. Lognormal and Gamma distributions aligned better with the central peaks, while the Normal distribution more accurately captured the tails. Although no single distribution perfectly fits the …

The Rise Of Global Collaboration In China Policy Research: Evidence From Bibliometric Network Analyses, 2000–2025, Yu Xiao, Aaron Ley, Ping Xu

Political Science Faculty Publications

This study examines the evolution of China policy research and its growing role in global policy scholarship. Using bibliometric and social network analyses of 326 articles published in 20 high-impact political science journals from 2000 to 2025, we trace the field’s expansion, identify key thematic concentrations, and document the emergence of robust international collaboration patterns. Cross-national co-authorship networks reveal a clear transition from a fragmented, Western-centered structure to a dual-hub system anchored by Mainland China and the United States, while institution-level networks show that leading Chinese universities have become central collaborators and Hong Kong institutions continue to serve as critical …

Evolving Contexts And Diverging Strategies: Federalism And The Politics Of Immigrant Welfare Exclusion In The Us, Ping Xu, Ling Zhu, Sebastian Ege

Political Science Faculty Publications

The intersection of immigration and welfare has taken a central stage in the politics of social policy and garnered increasing scholarly attention in welfare politics research. While prior research has examined how immigration affects welfare support and welfare generosity in the US, less is known about the determinants of immigrant-related welfare policies. This paper investigates how state-level policymakers shape immigrant welfare policies in response to changing social and economic state contexts across the U.S. states from 2000 to 2020. Using data from the Urban Institute's Welfare Rules Database, we create a policy index of welfare inclusion of immigrants to track …

Governing Ai Without Agencies: Self-Regulatory Organizations And The Federal Backstop, Aram A. Gavoor

GW Law Faculty Publications & Other Works

Artificial intelligence is accelerating American innovation and strategic advantage. The governance task is to provide predictable compliance baselines that support scale and competitiveness while remaining workable under executive branch policy, statutory baselines, and the rules that now govern the administrative state. Congress remains slow and factional, and agencies face rising procedural and remedial constraints. Recent Supreme Court doctrine has reduced the administrative state’s interpretive and enforcement leverage. Regulated entities can challenge agency rules when those rules newly impose concrete harm, litigate statutory meaning without Chevron-style mandatory deference to agency statutory interpretations with limited exceptions, and invoke strengthened procedural safeguards in …

Deploying The “Trade Bazooka”: How The Anti-Coercion Instrument Reshapes Eu Public Procurement, Amanda Lythgoe, Christopher R. Yukins

GW Law Faculty Publications & Other Works

As trade disputes continue to batter the relationship between the U.S. and its partners in the European Union, a new countermeasure by the EU—the Anti-Coercion Instrument (ACI)—has emerged as a serious threat to trade flows, including in public procurement. Although formally framed as a trade-defense mechanism, the ACI is a legal instrument capable of addressing a broad range of economic coercion. Notably, although the ACI is presented as a means of deterrence and de-escalation, the ACI authorizes countermeasures that extend well beyond tariffs, and can severely restrict foreign firms’ access to EU public procurement markets. This article provides an historical …

Brief For International Law Scholars As Amici Curiae In Support Of Respondents, Cisco Systems, Inc. V. Doe I, William S. Dodge

GW Law Faculty Publications & Other Works

This amicus brief was filed with the U.S. Supreme Court on behalf of international law scholars in Cisco Systems, Inc. v. Doe I. The brief addresses whether claims for aiding and abetting violations of international human rights may be brought under the Alien Tort Statute. Part I argues that, under Sosa v. Alvarez-Machain (2004), whether aiding and abetting claims are actionable is determined by customary international law rather than U.S. domestic law. Part II argues that customary international law’s prohibition against aiding and abetting human rights violations meets the Sosa standard. Drawing on instruments establishing the Nuremberg tribunals, the International …

Two Heads Are Better Than One: Integrating International Law And Global Public Health Approaches To Firearm Violence To Promote Public Safety And Human Rights, Arturo J. Carrillo, Jonathan E. Lowy

GW Law Faculty Publications & Other Works

In his Advisory of June 25th, 2024, the U.S. Surgeon General, Vivek H. Murthy, declared firearm violence a public health crisis and presented a damning picture of the widespread deaths, injuries and trauma caused by gun violence in the United States. A critical feature of the firearm violence crisis in the United States that the Surgeon General did not expressly address in his report–or even mention–is the role of the manufacturers, distributors, and dealers of firearms, collectively referred to as “the gun industry.” It is an open secret that the U.S.-based firearm industry engages in manufacturing, marketing, distribution and sale …

Shrinkflation And Consumer Demand, Aljoscha Janssen, Johannes Kasinger

Research Collection School Of Economics

This study investigates shrinkflation—the practice of reducing product size while maintaining or slightly changing prices—in the U.S. retail grocery market. We analyze a decade of retail scanner data to assess the prevalence and patterns of product size changes across various product categories. Our findings show that approximately 1.92% of products have been downsized. When comparing total sales, product downsizing is more than five times as prevalent as upsizing. Product downsizing typically occurs without a corresponding decrease in price and is widespread across product categories. Consequently, consumers end up paying more per unit volume. We further find that consumers are more …

Childlessness And Health In Middle Age And Older Adulthood: Evidence From Singapore, Christine Ho, Dahye Kim, Rohan Ray, Bussarawan Teerawichitchainan

Research Collection School Of Economics

Health and well-being in mature adulthood are important concerns given the prevalence of individuals aging without children. We exploit two new instruments for childlessness— infertility and the number of childless siblings—and condition our analyses on a rich set of covariates including childhood health and financial status, to investigate the causal relationship between childlessness and health in middle age and older adulthood. Using a nationwide dataset of 1,500 Singaporeans aged 50 and above, we show that OLS underestimates the negativeeffects of childlessness on health. We find that childlessness leads to higher likelihood of poorer self-reported health and mental distress. The results …

Bargaining Inefficiency Due To Mispricing Under Incomplete Information : Evidence From The Bilateral Oligopolistic Containership Time Charter Market, Jaeung Cha

World Maritime University Ph.D. Dissertations

A well-established body of bargaining studies theoretically demonstrates that inherent limitations in observing the counterplayer’s private information give rise to an incomplete information setting in bargaining, leading to efficiency losses associated with mispricing, costly delays, and even bargaining failures. As the shipping market, a business-to-business market in which products are generally heterogeneous and the number of both sellers and buyers is limited by high entry/exit barriers, relies on a bargaining mechanism to determine tailored transaction prices, market pricing is prone to inefficiencies associated with incomplete information. However, the relevant empirical evidence remains underexplored in both the shipping finance and bargaining …

Integrating Literacy Into A High School Climate Change Unit, Bailey Bushman

Graduate Research Papers

The ability to read is an important skill for members of society. Teaching students to read is often left up to elementary teachers and then secondary English teachers are expected to expand on those skills, but other content areas can help teach the needed literacy skills to students. In addition to typical literacy skills like reading and writing, students need to be able to understand climate science in order to make responsible decisions about the Earth’s future.

One way to ensure that students are getting both literacy skills and disciplinary content would be for science teachers to include a variety …

Outcomes Of Allogeneic Ocular Surface Stem Cell Transplantation, Albert Y. Cheung, Natalia Quiroz-Casian, Enrica Sarnicola, Gautam C. Ramanathan, Siddharth Nath, Edward J. Holland

Department of Ophthalmology Faculty Publications

Allogeneic ocular surface stem cell transplantation (OSST) is an established therapeutic approach for limbal stem cell deficiency, utilizing techniques such as keratolimbal allograft (KLAL), living-related conjunctival limbal allograft (lr-CLAL), allogeneic cultivated limbal epithelial transplantation (allo-CLET), and allogeneic simple limbal epithelial transplantation (allo-SLET). This review synthesizes evidence from 35 studies encompassing 1, 268 eyes with at least 24 months of follow-up to evaluate intermediate- and long-term outcomes. Overall, OSST is associated with improvement in visual acuity and restoration of ocular surface stability, although success rates vary widely by technique, ranging from 13% to 87%. Outcomes appear to be influenced by the …

Ocular Surface Disease Following Lasik And Cataract Surgery: A Review Of Their Interrelated Complications, Matthew D. Spangler, Nila Kirupaharan, John D. Sheppard

Department of Ophthalmology Faculty Publications

Background: Ocular surface disease is a multifactorial condition that is very commonly caused by dry eye disease (DED). Ophthalmic procedures intended to improve visual outcomes, laser-assisted in situ keratomileusis (LASIK) and cataract surgery, can paradoxically cause or exacerbate underlying ocular surface disease. This results in worsening vision and quality of life.

Areas covered: This review examines the pathophysiological mechanisms contributing to ocular surface disease development following LASIK and cataract surgery. Both procedures are associated with the transection of corneal nerves, leading to decreased tear production, surface instability, altered neurotrophin production, and impairment of the blink reflex. Furthermore, these incisional procedures …

Hyphema Associated With Water Bead Projectile Toys: A Retrospective Comparative Study, Aashri I. Aggarwal, Priya K. Singh, Diego E. Arias, Peter A. Netland

Department of Ophthalmology Faculty Publications

Purpose: Superabsorbent water beads can be used in projectile toy guns. We aimed to characterize water bead-related hyphema and compare the prevalence with other causes of traumatic hyphema.

Methods: In this 10-month retrospective review, we identified 35 consecutive patients with traumatic hyphema presenting to the emergency department. Cases were grouped by injury mechanism, water bead-related compared with all other causes. Clinical data on initial presentation and subsequent visits were compared.

Results: In the patients with traumatic hyphema, 8 (23%) cases were due to water bead trauma. Bead-related cases involved significantly younger patients (16 ± 9 years) compared with other cases …

Board Attributes, Firm Performance, And The Moderating Role Of National Culture: A Meta-Analysis, Matthew Farrell, Chris H. Willis, Nathapon Siangchokyoo, Ryan L. Klinger, Jamil Kreugel, Hami Usta, Timiry R. Tian, Ying Thaviphoke, Samuel Wilson

Management Faculty Publications

Research Question/Issue

The impact of board structures on firm performance remains a contentious governance topic with competing theoretical paradigms and inconclusive empirical support. Scholars propose that national culture could reconcile contradictory evidence; yet, argumentation is fragmented and direct tests are rare. We meta‐analyzed 513 samples across 54 countries to examine relationships between board structures (i.e., board size, board independence, and CEO duality) and firm performance. We model national culture, using Hofstede's six cultural dimensions, as moderators to test whether these relationships align with agency or stewardship theory across different cultural settings.

Research findings/insights

Findings indicate a substantial moderating role of …

What Makes An Internationalizing Firm Entrepreneurial?, Daniel R. Clark, Robert J. Pidduck, Nicole E. Coviello

Management Faculty Publications

Zahra et al. (2024) argue that prior research has insufficient understanding of the entrepreneurial nature of internationalization. To address this, they integrate theories from management and international business to develop a firm-level typology that incorporates (1) the degree of radicalness of the firm’s entrepreneurial behavior and (2) the firm’s level of foreign market commitment. We advance these efforts by proposing that, to understand what makes an internationalizing firm entrepreneurial, researchers will also benefit from direct insights from entrepreneurship research. We retain Zahra et al.’s (2024) behavioral focus in our arguments but shift attention to the individuals …

The Emerging Social Media Water Cooler? Motivations For Reddit Use In A Niche League, Jan Boehmer, Brendan O'Hallarn

Communication & Theatre Arts Faculty Publications

Social media play a key role in sport marketing—with athletes, teams, and leagues directly engaging with their audiences. While Facebook, Instagram, and Twitter have received much attention in the sport marketing and communication literature, research on Reddit is scant. This is particularly noteworthy, as the platform is growing rapidly and promises utility for users with nonmainstream interests to find and engage with each other. This study employs a uses and gratifications approach to investigate how prevalent Reddit use is among fans of the United Football League (UFL), what motivates users to engage with the platform, and whether Reddit use leads …

Stages Of Being Foreign As Portrayed In Daughter Of Keltoum And Lost Birds, Fran Hassencahl

Communication & Theatre Arts Faculty Publications

In this paper, I use the intercultural communication model, The Stages of Being Foreign, developed by anthropologist Oberg (1960) and modified by Gullahorn & Gullahorn (1963), Lewis & Jungman (1986), and Ward, Bochner, and Furnham (2001) to explain the experience of culture shock. This model describes the stages that individuals experience when they leave, either voluntarily or involuntarily, their home country/culture and must adapt to a new culture. These stages as described by Oberg are a preliminary stage (a spectator stage), an increasing participation stage, the pit of the culture shock stage, the adaptation stage, and for some migrants a …

Enlem: Ensemble Learning-Based Model To Detect Phishing Websites, Most Nilufa Yeasmin, Md Abu Rumman Refat, Bikash Chandra Singh, Zulfikar Alom, Zeyar Aung, Mohammad Azim

School of Cybersecurity Faculty Publications

Phishing involves manipulating individuals into revealing private data, e.g., user IDs, bank details, and passwords. The observed surge in fraud is related to increased deception, impersonation, and advanced online attacks. Thus, effective phishing detection methods are required to mitigate escalating global phishing threats. Existing methods (e.g., heuristics-based, signature-based, and visual similarity-based methods) attempt to detect phishing sites, and machine learning (ML) and deep learning (DL) methods are effective in the cybersecurity context in terms of learning from data, offering insights, and forecasting. However, independent ML algorithms are limited when handling complex data, and DL techniques surpass traditional ML methods in …
