English Diphthongs For English Learners: The Same, But Different, Kristin Lems

Faculty Publications

In any language, diphthongs need to be reckoned with, but teaching diphthongs to learners of English as a new language requires greater insight and special skills. In this column, we take a look at English diphthongs, why they matter, and how they might be best handled when teaching English language learners.

Private Coverage, Public Risk: The Role Of Cyber Insurance In National Security Governance, Deborah L. Johnson

Faculty Publications

This Article explores the growing yet underexamined role of the commercial cyber insurance market in shaping the United States' approach to cybersecurity readiness. It argues that, as cyber threats against U.S. critical infrastructure and essential services increase, commercial cyber insurance has quietly come to function as a de facto governance tool in national cybersecurity. In hospitals, water and energy systems, and other public-facing sectors, policy language, underwriting questionnaires, and post-breach claims practices help define what counts as "reasonable" security, influence how organizations plan for and respond to incidents, and affect the pace and scope of recovery after an attack. Yet …

Artificial intelligence-augmented additive manufacturing (AI2AM) represents a transformative frontier in digital fabrication, where artificial intelligence (AI) is embedded not as a peripheral tool, but as a central framework driving intelligent, adaptive, and autonomous additive manufacturing (AM) systems. The objective of this Roadmap is to present a comprehensive vision of the state-of-the-art developments in AI2AM while charting the future trajectory of this rapidly emerging field. As AM applications continue to expand across diverse sectors, conventional design and control strategies face growing limitations in scalability, quality assurance, and material complexity. AI uses tools like computer vision, generative design, and large language models …

The Psychology Of A Favor: Why Hidden Witness Payments Demand A New Brady Rule, Adam M. Gershowitz

Faculty Publications

Prosecutors and the police regularly pay informants and other witnesses in criminal cases. These payments can be in the form of rewards, relocation expenses, crime victims funds, and even simple cash. Although witness payments are legal, prosecutors are supposed to disclose them under the Brady doctrine because they are favorable evidence that the defense could use to impeach the witness. Yet prosecutors often fail to disclose witness payments because of communication failures with the police, poor training, excessive caseloads, and occasional ethical lapses.

This Article examines dozens of hidden witness payments that prosecutors failed to disclose. In nearly eighty percent …

Administering Election Disputes, Rebecca Green

Faculty Publications

U.S. election administration has become supercharged with controversy. A process that should be mundane—casting and counting votes—has become the target of relentless litigation, much of which ends in non-merits rulings that risk perpetuating rather than resolving public concerns. The high volume of election litigation is costly, strains election officials, and risks eroding public trust in both elections and the courts. Recognizing the need to resolve election claims fairly and efficiently, Administering Election Disputes examines administrative remedies as an under-theorized alternative to judicial resolution. Increased use of well-designed administrative election dispute resolution (AEDR) could reduce pressure on courts, deliver faster and …

Conflict As Catalyst: The Role Of Conflict In Creating Political Space For Women, Christie S. Warren

Faculty Publications

Although the benefits associated with the presence of women in political decision-making positions are uncontested, global statistics relating to the number of women in political leadership roles paint a disappointing picture of underutilized resources. While rights-based advocacy, quotas, and economic incentives are commonly posited as effective strategies to increase the number of women active in public spaces, several studies have shown that the law alone is not sufficient to bring about changes in gender norms unless the underlying structural constructs that perpetuate inequalities privileging dominant groups are addressed first. Conflict, especially when driven by rejection of those inequalities, can hasten …

“El Concilio De Buen Manejo” Spmdtu Council No. 2, Capulín, Colorado, José A. Rivera Ph.D

Faculty Publications

From among the sixty-four local councils affiliated with the Sociedad Protección Mutua de Trabajadores Unidos (SPMDTU), Council No. 2 at Capulín was among the earliest organized, quickly grew in membership, and was known for its attention to recordkeeping of minutes, financial ledgers, and attendance logs. The council was established around 1901, and by midcentury a history of the SPMDTU noted: “Este concilio siempre ha tenido buen manejo. Tiene buena propiedad con su propio salón y ha llegado a tener buen número de miembros.” (This council has always enjoyed good management. It has a nice property with its own …

Individualized Cannabis Reparations, Scott Bloomberg

Faculty Publications

This Article makes an argument that should be obvious. The best way for governments to right the wrongs of cannabis prohibition is to give money to people with cannabis offenses. Nonetheless, this straightforward reform has been consistently overlooked, dismissed, or minimized by policymakers and scholars alike, eschewed in favor of other social equity programs that do not right those wrongs nearly as effectively. Governments have indeed invested hundreds of millions of cannabis tax dollars in social equity licensing programs and community reinvestment initiatives. These programs-while often worthwhile-do not benefit the vast majority of people with past cannabis offenses. Governments should …

Beyond A Protagonist Bias In Narrative Identity Research: Methods For Identifying Master Narratives In Interview Data, Andrew D. Coppens, Jayson Seaman, Cindy Hartman

Faculty Publications

This article advances a methodological shift in narrative identity research by addressing the field’s protagonist bias – the tendency to rely on first-person autobiographical accounts as the primary evidence for identifying cultural master narratives. We integrate Erikson’s psychosocial identity framework, Vygotsky’s “tool and result” methodological insight, and sociolinguistic approaches to narrative to develop a three-stage analytic logic: (1) identifying small-n narratives through scenes conveyed in discourse; (2) grouping these into Big-N narratives that cohere thematically across scenes (Tannen, 2007, 2008); and (3) assessing candidate master narratives using McLean and Syed’s (2016) five criteria. We demonstrate this approach through a case …

Introduction Interventions that address household-level factors, including food insecurity (FI) and poverty, may reduce HIV risk and improve sexual and reproductive health (SRH) among adolescent girls and young women (AGYW).

Methods This cluster randomised controlled trial in Kenya assessed AGYW living in households of adults enrolled in Shamba Maisha (SM). SM was a multisectoral agricultural livelihood intervention designed to improve HIV health. At the trial end, we used linear and logistic regressions to compare differences between the intervention and control arms in FI, and mental health among AGYW-caregiver pairs and SRH outcomes among the AGYW, accounting for clusters with robust …

Inexorably Entangled Environmental And Knowledge Commons, Todd Aagaard, Brett M. Frischmann

Faculty Publications

For people to effectively share an environment, they usually also must effectively share knowledge about that environment. While seemingly obvious and intuitive, this insight is often overlooked in literature about governing resources as commons. Focusing on the knowledge commons associated with an environmental commons helps to illuminate a host of complex governance dilemmas. This chapter examines the interrelationship between environmental and knowledge commons, weaving together different strands of commons research and practice. Examples discussed include shared pastures, forests, road systems, computer servers, social media platforms, living rooms, and antimicrobial effectiveness/resistance.

Explaining Variability In Employee Perceptions Of Hr Practices In Strategic Hrm Research: An Integrative Review And Future Outlook, Jeske Van Beurden, Susanne Beijer, Kaifeng Jiang, Karina Van De Voorde, Anthony Nyberg

Faculty Publications

Employee perceptions of human resource (HR) practices have become a central focus in strategic human resource management(HRM) research due to their impact on individual and organizational outcomes. Recent studies highlight the importance of un-derstanding how these perceptions are formed, what they encompass, and why they vary across employees. This special issue ofHuman Resource Management aims to advance this evolving area of research by focusing on variability in employee perceptionsof HR practices. We review the current literature on employee perceptions of HR practices, including (1) theoretical and concep-tual clarity of the employee perceptions of HR practices construct, (2) antecedents of these …

Crepe Myrtle Bark Scale (Acanthococcus Lagerstroemiae) And Sooty Mold (Capnodium Sp.) Decrease Bloom And Fruit Number In ‘Natchez’ Crepe Myrtle (Lagerstroemia Xfauriei ‘Natchez’), Derald A. Harp, Beatriz Ruiz, Kara Bailey, Pedro Castillo, Phoebe Alvarez

Faculty Publications

Crepe myrtle bark scale (CMBS) (Acanthococcus lagerstroemiae) is an important pest of crepe myrtle in Texas, and infestations are accompanied by excessive growth of sooty mold (SM) that will cover stems, and, in severe cases, leaves. These combine to create significant stress on the plant, and anecdotal evidence suggests a decrease in bloom number under heavy infestation. In an existing planting of 24 ‘Natchez’ crepe myrtle in four blocks, three trees were randomly chosen in each block and treated with either a dinotefuran (year 1) or imidicloprid (year 2) drench. The three remaining trees were untreated. In February of year …

Examining The Relationships Between Students’ Achievement Goals And Their Academic Achievement In An Oer-Based Course: A Person-Centered Approach, Hengtao Tang Ph.D., Yan Yang, Yu Bao

Faculty Publications

Open Educational Resources (OER) have emerged as a cost-effective alternative to traditional commercial textbooks in higher education, towards the goal of alleviating college students’ financial burden of educational expenses. However, mixed findings about the influences of the integration of OER on student learning are present. To address the gap, this study investigated whether student motivation in OER served as a latent factor that impacts their academic achievement in online asynchronous courses offered in public universities. Particularly, this study (N = 247) implemented an advanced person-centered approach—stepwise latent class analysis—to profile student achievement goals in an OER-based course and examined their …

Faculty Publications

Open data and code are crucial to increasing transparency and reproducibility, and in building trust in scientific research. However, despite an increasing number of journals in ecology and evolutionary biology mandating for data and code to be archived alongside published articles, the amount and quality of archived data and code, and subsequent reproducibility of results, has remained worryingly low. As a result, a handful of journals have recruited dedicated data editors, whose role is to help authors increase the overall quality of archived data and code. There is, however, a general lack of consensus around what a data editor should …

Rewriting The Rules: Game-Based Learning For Affective And Cognitive Student Engagement In An Undergraduate History Course, Rachel Hoke, James Risk

Faculty Publications

Constructivist psychology has long demonstrated the potential for play to offer various benefits to learning. This study introduced active game-based learning experiences, in the form of role-playing games, into an undergraduate history course that also included passive lecture and discussion elements. Mixed methods student feedback surveys were used to examine the impacts of game-based learning on students’ affective and cognitive engagement in the course and offer a comparison between the lecture and game-based learning experiences. Qualitative data were analyzed through the paradigm of Mohsen, Abdollahi, and Omar’s (2019, 518-520) framework for educational value, including affective evaluation, conceptual understanding, skill development, …

Efficient Energy-Stable Discontinuous Galerkin Schemefor The Non-Isothermal Cahn–Hilliard–Navier–Stokestwo-Phase Fluid Flow System, Guang-An Zou, Meiting Wang, Kejia Pan, Yin Yang, Xiaofeng Yang

Faculty Publications

In this article, we propose a novel numerical framework for the non-isothermal Cahn–Hilliard–Navier–Stokes two-phase flow system, which couples the incompressible Navier–Stokes equations, the Cahn–Hilliard phase-field equation, and the heat transport equation to capture temperature-dependent two-phase flow dynamics. The pro-posed scheme achieves three major advances: (i) unconditional energy stability through a combined scalar auxiliary variable (SAV) and zero-energy-contribution (ZEC) approach, (ii) linearity and full decoupling of all variables while using a second-order temporal discretization, and (iii) efficient implementation via discontinuous Galerkin (DG) spa-tial discretization together with a second-order projection method for the Navier–Stokes equations. We rigorously prove the unconditional energy stability …

More Rights, More Danger For Police: An Experimental Look At How Messaging Shapes Public Views About Constitutional Carry, Hunter M. Boehme, Paige Vaughn

Faculty Publications

Constitutional carry (CC) laws, now enacted in 29 states, allow individuals to carry firearms openly without permits, yet little is known about public perceptions of these laws. This study employs a pre-registered survey experimental design to investigate whether varying support for CC laws by police leaders and politicians influences attitudes toward the laws and their perceived consequences. One-third of respondents supported CC laws, with most disagreeing that they will make communities safer. The majority of the sample felt these laws would increase personal liberty but also felt these laws would increase police danger. Oppositional messaging increased agreement that the laws …

Cognitive And Emotional Conflict Control Among Children Affected By Parental Hiv/Aids In China, Huihui Wang, Juan Liu, Danfeng Wen, Wan Zhao, Xiaoming Li Ph.D., Junfeng Zhao

Faculty Publications

Background: Children affected by parental HIV/AIDS constitute a particularly vulnerable population, often facing heightened risks in psychosocial adaptation due to family disruption, social stigma, and resource deprivation. However, the characteristics of their executive functions, particularly the core component of conflict monitoring, remain unclear.

Methods: The present study compared the performance of children affected by parental HIV/AIDS (n=32) to a control group (n=32) on a cognitive conflict and emotional conflict face-word Stroop task.

Results: The results of the cognitive Stroop task demonstrated that both groups showed better performance in congruent stimuli compared to incongruent stimuli (86.20% vs.67.30%; 568.43ms vs.586.04ms). In the …

Korean Words In The Oed: Race, Gender, And The Modern English Speaker, Elaine W. Chun

Faculty Publications

This article examines representations of the Modern English Speaker of Korean (MESK) in the Oxford English Dictionary (OED), as lexicographers listened to and documented the language of this figure over the past century. I show that, until the early twenty-first century, the most salient type of MESK was the Koreanist, a white, masculine expert on and translator of Korean, the language of a racial other. By contrast, more recent Korean entries, influenced by the global spread of hallyu, have invoked the Korea Fan, a figure that potentially unsettles longstanding ideologies of language, race, and gender. I …

Hybrid Cnn–Gru-Based Demand–Supply Forecasting To Enhance Sustainability In Renewable-Integrated Smart Grids, Süleyman Emre Eyimaya, Necmi Altin

Faculty Publications

The rapid integration of renewable energy sources in smart grids has introduced significant uncertainty in both power generation and consumption patterns, posing challenges to environmental, economic, and operational sustainability. Accurate short-term forecasting of energy demand and supply is essential for achieving optimal scheduling, grid stability, and resilient operation in renewable-integrated power systems. This study proposes a hybrid deep learning framework combining Convolutional Neural Networks (CNN) and Gated Recurrent Units (GRU) for intelligent joint demand–supply forecasting in smart grids. The model was developed and implemented in MATLAB using real-world datasets comprising electricity consumption, photovoltaic (PV) generation, temperature, and irradiance variables. Comparative …

Dynamic Magnetic Null Behavior In Planar Ion Diodes: Particle-In-Cell Analysis Of Field Oscillations And Ion Beam Dynamics, Jesse C. Foster, Stephen B. Swanekamp, Paul F. Ottinger

Faculty Publications

Particle-in-cell simulations of a 1.75 MV, 375 kA, and 50 ns planar pinched-beam diode reveal that the strongest gigahertz-frequency oscillations in electric field and ion current arise from the dynamic motion of the magnetic null near the anode tip. These oscillations, which appear when the ion transit time becomes comparable to the local field-variation timescale, periodically expand the effective anode–cathode gap and generate bursts of over-accelerated ions. The resulting ion energy spectrum broadens substantially near the null while maintaining excellent beam uniformity along the anode. The simulations, therefore, demonstrate a direct physical linkage between ion transit time instability and magnetic …

Disciplining Mechanisms: Governing Data Markets With Competition And Regulation, Peter Ormerod

Faculty Publications

The past decade has witnessed conceptual renewals in both competition law and information privacy law. These regulatory movements—Neo-Brandeis antitrust and structural data governance—share the objective of recalibrating the balance of power between individuals and the massive data-processing firms that now dominate modern life.

Despite their common ends, policy interventions drawn from these schools of thought can work at cross purposes: competitive pressure can induce data exploitation, and privacy rules tend to benefit the largest firms.

This Essay exposes the friction in their relationship and offers guidance on how to mediate their tension. Competition policy alone will prove ineffective at indirectly …

Demography And Dispersal Influence The Relationship Between Habitat Suitability And Population Density, Cleber Ten Caten, Tad Dallas

Faculty Publications

A central goal of ecology is to understand spatial patterns of species densities. Habitat suitability estimates from species distribution models (SDMs) could be used to represent species density and overcome the scarcity of density data. However, there is mixed evidence that habitat suitability is a reliable descriptor of density, and it is suggested that local dynamics affect the relationship between habitat suitability and density. We simulated population dynamics for 200 virtual species considering different combinations of factors (demographic stochasticity, dispersal, and intraspecific competition) that affect population sizes and SDMs were trained using different sets of environmental predictors to evaluate when …

Online Age Gating: An Interdisciplinary Evaluation, Noah Apthorpe, Brett Frischmann, Yan Shvartzshnaider

Faculty Publications

The recent surge in regulation seeking to establish age-based governance online is part of a decades-long attempt to establish online zoning. It is driven by active development of technologies to estimate or verify user age based on various characteristics of users, their credentials, or their activities. However, these developments have heightened prevailing concerns that online age gating technology will inevitably be abused and misused to cause a variety of privacy harms and rights infringements. This paper examines this ongoing debate by bridging technical and legal scholarship to explore the current state of online age-based governance. We discuss the current legal …

Levers Of Default: Can The President Unilaterally Alter The Terms Of The National Debt?, Lev E. Breydo, Nathan B. Oman

Faculty Publications

The inviolability of America’s $30 trillion debt is a cornerstone of global markets and the U.S. economy. This Essay identifies a critical loophole: the President’s underappreciated power to dramatically change its legal structure—and argues that Congress should act to prevent a potential catastrophe.

The Essay details, for the first time in the literature, the arcane legal architecture underpinning America’s sovereign borrowings. Our analysis finds that although the President lacks authority to change the terms of outstanding debt retroactively, the President can accomplish similar goals by issuing new debt instruments that embed unprecedented powers. In surprisingly short order, a determined Executive …
