Mitigating And Preparing For Disasters At The Organizational Level: A Global Systematic Literature Review, Abdul-Akeem Sadiq, Ratna B. Dougherty, Rebecca Entress, Bikash Adhikari, Katherine Wilson Mccoy, Emilie Rott, Grace L. Chikoto-Schultz, Shannon Maharajh

Faculty Scholarship and Creative Works

Organizations play significant roles in society by providing goods and services and contributing to the economies of communities, globally. Amid the predicted increase in the frequency and impact of disasters, which will invariably lead to higher disaster costs, there is an urgent need to ameliorate disaster impact on society and organizations. Disaster mitigation and preparedness are strategies for stemming disaster impact and losses within organizations. Cognizant of the importance of disaster mitigation and preparedness, researchers have conducted a myriad of studies on both concepts at the organizational level. To advance knowledge on this topic, this study conducted a comprehensive systematic …

Spatiotemporal Habitat Use, Sex-Specific Movement, And Site Fidelity Of Walleye In Lake Sharpe, Sd, Carter S. Dollen

Electronic Theses and Dissertations

Walleye Sander vitreus are a popular sportfish among anglers in South Dakota with large economic impacts to local communities. A popular destination for Walleye anglers is Lake Sharpe, a 25,000-ha reservoir on the Missouri River, in central South Dakota. Gill net catches in Lake Sharpe show high annual variation, prompting concern that gill net catch rates may be poorly related to population abundance. A better understanding of Walleye movement and distribution could lead to increased precision in annual abundance estimates and improved active management that increases angler success. The goals of this study were: 1) determine spatiotemporal movement patterns of …

Formulation And Immunogenicity Of L1 Orf1 Mrna Vaccine In Mice, Raj Nandani

Electronic Theses and Dissertations

This dissertation presents the design, formulation, and immunogenicity evaluation of a novel mRNA vaccine targeting the L1 ORF1p protein, a tumor-associated antigen. The vaccine was synthesized using in vitro transcription and encapsulated in lipid nanoparticles (LNPs), with both unmodified uridine and N1-methylpseudouridine variants tested. Physicochemical characterization confirmed optimal particle size (160–220 nm), acceptable zeta potential, and encapsulation efficiency ranging from 74% to 92%, with preserved RNA integrity post-formulation. These results validate the robustness of the formulation workflow and its suitability for antigen delivery. Immunogenicity studies in C57BL/6 mice revealed modest but promising immune responses. While early activation markers (CD69) and …

Epidemiological And Diagnostic Approaches For Soybean Cyst Nematode In South Dakota, Nabina Karki

Electronic Theses and Dissertations

Soybean cyst nematode (SCN), Heterodera glycines (HG) Ichinohe, is an endoparasitic nematode and one of the major yield-limiting pathogens of soybean (Glycine max L.) in the United States. Soybean cyst nematode alone accounts for more than $1.5 billion economic loss annually in North America. First reported in the U.S.A. in 1954 in New Hanover County, North Carolina and later in 1995 in Union County, South Dakota. Prior to this study, SCN has spread in 34 counties in the state. As a soil pathogen, which can adapt to most soil conditions under soybean production and beside soybean, it is hosted on …

Evaluation Of Two Stem Boring Insects In South Dakota: A Survey Of Wheat Stem Sawfly And Determining The Impact Of Planting Date On Dectes Stem Borer Infestations In Sunflowers, Khuma Kumari Bhusal

Electronic Theses and Dissertations

Wheat, Triticum aestivum L., and sunflower, Helianthus annuus L., are major crops in South Dakota that are threatened by stem-boring insect pests capable of reducing yield and harvestability. In wheat, the wheat stem sawfly, Cephus cinctus Norton, has long been recognized as a destructive pest in the Northern Great Plains, yet its actual distribution within South Dakota remained uncertain. To determine its presence, a two-year survey was conducted across the state from 2023–2024, during which one to four wheat fields per county were sampled using standardized sweep net transects. Wheat stem sawflies were collected only from Harding and Perkins Counties …

What Might Contract Theory Be?, Gregory Klass

Georgetown Law Faculty Publications and Other Works

Few contract theories begin with so comprehensive a discussion of method as does Stephen Smith’s book, Contract Theory. In the first chapter, “What Is Contract Theory,” Smith describes an interpretive approach guided by four goals: fit with the existing law, internal coherence, moral attractiveness, and transparency to legal actors.

This chapter in Understanding Private Law: Essays in Honour of Stephen A. Smith, does a deep dive into Smith’s description and defense of those goals. Smith pictures the contract theorist as an observer standing outside legal practice, interpreting the law but not participating in it. That picture results in …

Mind The Gap(S): Mitigating Harassment In A Post-#Metoo Workplace, Jamillah Bowman Williams, Elizabeth C. Tippett, Anu Ramdin

Georgetown Law Faculty Publications and Other Works

In a post-#MeToo workplace, harassment remains pervasive, and harassment law still fails to provide protection for the harms experienced by many workers—particularly those in the most vulnerable jobs. Even when reform efforts are introduced through legislation, courts, and agency guidance, it often does not provide greater power, autonomy, and dignity to women in ways that would more meaningfully protect them from workplace abuse. We are the first to create a database of state legislation, including over three thousand bills, that allows us to empirically analyze the extent to which lawmakers comprehensively address harassment following the rise of the #MeToo movement. …

The Scope Of The Prior Art, John R. Thomas

Georgetown Law Faculty Publications and Other Works

The courts and the U.S. Patent and Trademark Office (“USPTO”) assess whether an invention may be patented by comparing it to the state of the art, which the patent community terms the “prior art.” Heavily influenced by Oliver Wendell Holmes Jr. and Learned Hand, and more recently expanded by the America Invents Act, the Patent Act features the broadest definition of prior art in U.S. history. No matter how remote, evanescent, or obscure, any activity or publication that occurs one day before the inventor files a patent application—anywhere in the world—may prove patent-defeating.

The government also holds patent proprietors accountable …

Pozen And The Puzzle Of Counterfactuals, Louis Michael Seidman

Georgetown Law Faculty Publications and Other Works

The Constitution and the War on Drugs, David Pozen’s carefully researched and brilliantly argued book, is both illuminating and disturbing: illuminating because it unearths forgotten moments when judicially formulated constitutional doctrine that could have ended or sharply restricted the War on Drugs were well within the Overton Window, and disturbing because it surfaces hard questions about historical contingency and the scope of the change that might have occurred in a counterfactual world. In this review, the author argues that the failure to specify both the nature of the counterfactual and the breadth of the alternative possibility have confused discussions …

Asking The Right Questions About Legal Finance In United States Aggregate Dispute Resolution, J. Maria Glover

Georgetown Law Faculty Publications and Other Works

Third-party legal finance is one of the most controversial modern developments in civil justice, both in the United States and across the globe. It is particularly controversial when mentioned in the same breath as aggregate litigation. Current debate trains on a series of repeated questions: whether and how to ban litigation finance in aggregate litigation; whether the use of litigation finance should be disclosed in discovery; and whether litigation finance is allowed under various (and often ancient) legal doctrines. Obscured from view is what I believe to be the most fundamental question: What is the proper role of litigation finance …

Pave Outer Space And Put Up A Parking Lot: Lagrange Points Should Be The Common Heritage Of Mankind, David A. Koplow

Georgetown Law Faculty Publications and Other Works

Outer space offers a vast array of opportunities, with different locations or regions available for exploitation by diverse users for a growing variety of satellite functions. But not all sectors of space are equally valuable for all applications, and the most desirable venues can become crowded, affording a premium for those who gain access first and impeding the development of a fair and efficient all-inclusive international legal regime.

This article focuses on Lagrange points, a finite series of special locations in space where the gravitational forces from a pair of large celestial bodies interact in unusual ways. These points afford …

Law Librarians As Content Preservers And Mediators For Modern Legal Researchers, Austin Martin Williams

Georgetown Law Faculty Publications and Other Works

Even though libraries have existed for thousands of years, one must wonder what role law libraries play and, more importantly, what roles law librarians play in supporting students, faculty, lawyers, and judges with so much information now available online? What value do law librarians add for today’s legal researchers?

At their core, law librarians continue to strive to perform two major functions: (1) “select, organize, and preserve legal information” and (2) help lawyers, judges, students, and faculty locate and use that information. This article hopes to explain just why it is important that law librarians continue to serve in these …

Does The Original Meaning Of The Fourteenth Amendment Protect Economic Liberty?, Randy E. Barnett

Georgetown Law Faculty Publications and Other Works

In my remarks today, I will defend the proposition that the original meaning of the Fourteenth Amendment protects "economic liberty." To clarify the issue, let me being by defining economic liberty. I define economic liberty as the right to acquire, use and possess private property and the right to enter into private contracts of one's choosing. If these rights are protected by the original meaning of the Fourteenth Amendment, then we can conclude that the Amendment does protect economic liberty.

In my view, the evidence that the original meaning Fourteenth Amendment protects rights of private property and contract is overwhelming. …

Just Research And Citation, Amanda Levendowski

Georgetown Law Faculty Publications and Other Works

Contemporary research and citation practices are often unjust. Data cartels like Westlaw and Lexis have parent companies that prioritize profits in ways that threaten immigrants. Even before the Dobbs decision, search engines could be deployed to weaponize data against pregnant people seeking reproductive care. Women and people of color have been legal scholars for more than a century but, as many scholars have observed, colleagues consistently under-cite, mis-cite or appropriate those scholars’ work with minimal recourse. Citation materials are often inaccessible to disabled people, poor people, or the public due to poor design, paywalls, or unpreserved content that falls prey …

Promoting Public Health And Public Safety By Ending The Exclusion Of Incarcerated Children From Access To Medicaid, Eduardo R. Ferrer

Georgetown Law Faculty Publications and Other Works

This essay is a response to Professor Den Houter's article entitled Children are Not Inmates in which she effectively calls eliminating the exclusion of indigent incarcerated children from Medicaid coverage pursuant to the Medicaid Inmate Exclusion Policy (MIEP). This essay affirms and builds upon Professor Den Houter's recommendation. Part I of this response provides additional support for why ensuring system-involved youth receive timely, uninterrupted, high-quality behavioral health services is critical to improving both public health and public safety. Part II analyzes the benefits and risks attendant to excluding indigent incarcerated children from the MIEP. Part III proposes the implementation of …

De/Reconstructing Delinquency, Eduardo R. Ferrer

Georgetown Law Faculty Publications and Other Works

Hundreds of thousands of children are brought under the jurisdiction of delinquency courts every year in the United States. Despite the reality that most children engage in delinquent behavior during their adolescence, poor children, children of color, children with disabilities, and children who identify as LGBTQIA+ comprise a disproportionate number of those who become delinquency system-involved. These disparities exist by design. Their origins can be traced back to the flawed first principles upon which the juvenile court was built and, specifically, to the unduly expansive legal definition of delinquency that has undergirded the jurisdiction and power of the juvenile court …

I Hate Self-Care: A Criminal Defense Lawyer’S Lament, Abbe Smith

Georgetown Law Faculty Publications and Other Works

Don’t get me wrong—I think people should take care of themselves. They should eat well, exercise regularly, and get a good night’s sleep. They should spend time with friends and family. They should have hobbies and interests. With any luck, they should find true love. But in the past decade or two, and especially since the COVID pandemic, there has been a disturbing turn inward. I’m talking about the “self-care” craze, which has become its own pandemic, or at least epidemic.

…

In this Essay, I share my concerns about what I regard to be an excessive focus on self-care …

In The Footsteps Of Moose: Using Non-Invasive Techniques To Identify Cause-Specific Calf Mortalities And Evaluate Moose (Alces Alces) Movements Pertaining To Mineral Lick Locations On Ancestral Lands Of The Grand Portage Ojibwe, Anna B. Weesies

Electronic Theses and Dissertations

Following a sharp moose (Alces alces; mooz, Anishinaabemowin, Ojibwe language) population decline in northeastern Minnesota during the early 2000s, the Grand Portage Band of Lake Superior Chippewa initiated a long-term moose collaring effort to assess survival and mortality causes. Moose are a culturally important species to the Band, with annual subsistence hunts held on the Reservation and adjacent 1854 Ceded Territory. Continued research guides culturally appropriate management decisions aimed at bolstering calf and adult survival, helping to preserve this moose in Minnesota today and for subsequent generations. Chapter 1 identifies cause-specific calf mortality rates in this multi-predator system using minimally …

Cover Cropping Strategies For Improving Weed Suppression, Yashar Askarzadeh

Electronic Theses and Dissertations

Cover crops (CCs) play an essential role in sustainable agriculture by providing multiple ecosystem services. However, adoption remains low due to concerns about economic returns, management complexity, and potential yield reductions in cash crops. Applying CCs uniformly across fields without accounting for spatial variability can result in inconsistent outcomes. A precision cover cropping system (PCCS), which incorporates site-specific management zones (MZs), offers a more targeted approach to improving performance while minimizing costs and uncertainties. This study explores the interaction between CCs and field variability through complementary field and greenhouse experiments. The field experiment demonstrates that field heterogeneity significantly influences CC …

What Do We Get Out Of Our Entertainment? Empirically Determining The Differences Between Narrative Engagement And Flow Using Video Games, Lars Wagener

Electronic Theses and Dissertations

Immersion is an important aspect of entertainment media because it both drives the use of media and heightens one’s experience with that media (Nilsson et al., 2016). There are three core aspects of immersion. These aspects are (1) narrative engagement, (2) flow, and (3) enjoyment. This study set out to determine whether these aspects are statistically distinct from one another when observed in video games. The result indicated that these aspects were distinct from one another when examined through a structural equation model. This indicates that creating an overarching immersion variable that combines the different aspects of immersion may not …

Measurement- And Simulated Annealing (Sa) Optimization-Based Inductor Model Coupled To Chassis, Junyong Park, Reza Vahdani, Donghyun Kim

Electrical and Computer Engineering Faculty Research & Creative Works

In automotive systems, a metal chassis protects the components against the external environment. However, the metal chassis is conductive, which results in unwanted conducted emission (CE) coupling to electric components. An inductor used for power factor correction (PFC) is one of the affected components. When the inductor is mated with the metal chassis, the impedance of the inductor changes. It is also hard to predict the CE coupling due to the structure-dependent characteristics. That is, the CE coupling is not negligible and hard to clarify. Therefore, this article proposes an efficient modeling method for the inductor which is mated with …

Ai-Driven Traffic Scene Understanding Using Static Lidar Sensors, Elham Binshaflout, Chaima Zaghouani, Charalampos Antoniadis, Hakim Ghazzai, Nawfal Guefrachi, Ahmad Alsharoa, Sameh Najeh, Gianluca Setti

Electrical and Computer Engineering Faculty Research & Creative Works

Traffic congestion and road safety remain critical challenges in urban environments, driving the need for more effective traffic monitoring solutions. While recent advancements in computer vision have enhanced traffic perception, the dynamic viewpoint of autonomous vehicles is often insufficient for comprehensive traffic management. To address this gap, we propose an AI-driven framework for enhanced traffic scene understanding using static LiDAR sensors at road intersections. The system collects 3D point clouds from roadside static LiDAR sensors, providing a complete view of vehicles and pedestrians. We integrate state-of-the-art 3D object detection (i.e., PV-RCNN) and instance segmentation models (i.e., PointGroup3heads) to accurately identify …

Coupling Path Analysis Of Data Center Ssd Storage Systems Based On Visualization Technique, Xiangrui Su, Haran Manoharan, Jihun Kim, Lalit Kumar, Heewon Kang, Chunghyun Ryu, Chulsoon Hwang

Electrical and Computer Engineering Faculty Research & Creative Works

Electrostatic discharge (ESD) is a major source of electromagnetic interference, capable of causing damage, malfunctions, or disruptions in electronic devices. As a result, ESD immunity testing is a critical component of electromagnetic compatibility (EMC) standards. In this study, the radiation emitted from the ESD gun body over 2 GHz is characterized and modeled using Huygens' principle. The equivalent field source was validated across three different environments, demonstrating accuracy with errors of less than 10 dB. A coupling path visualization technique was then employed to identify critical coupling paths, providing guidance for the strategic placement of absorbers. Simulation results showed that …

Aperture-Based Fss For Dielectric Thickness Sensing, Alexander Hook, Gage Donahue, Kristen M. Donnell

Electrical and Computer Engineering Faculty Research & Creative Works

Frequency selective surfaces (FSSs) are planar arrays of patch- or aperture-based elements that have a particular transmissive or reflective response. As FSS performance is affected by changes in the local (to the FSS) environment, FSSs may be used to detect changes in strain, temperature, or nearby material (substructure) thickness, amongst other parameters. To this end, an aperture-based FSS can be considered as a sensor for substructure thickness monitoring for surface mounted sensing scenarios. An aperture-based design was selected due to its ability to operate in reflection mode (and hence a one-sided measurement) without the need for a conductive backplane. In …

Dual Parameter Fss-Based Sensing For Structural Health Monitoring Applications, Swathi Muthyala Ramesh, Doyle T. Motes, Kristen M. Donnell

Electrical and Computer Engineering Faculty Research & Creative Works

frequency selective surfaces (FSSs) are periodic arrays of conductive elements or apertures that reflect and/or transmit incident electromagnetic energy. Their response depends on parameters, such as element shape, unit cell dimensions, dielectric properties, and the local environment, making them suitable for structural health monitoring (SHM) applications. This article presents a dual-parameter FSS-based sensor design capable of measuring small-scale uni-directional longitudinal strain (0%–0.5%) and temperature (23 ◦C–223 ◦C). The sensor integrates two-unit cells: 1) a patch-based cell on a thin substrate for strain sensing, offering enhanced strain transfer and superior sensitivity (~16–18 MHz/0.1%) and 2) a loop-based cell with a temperature-sensitive …
