Lawfare And Terrorism – Can Terrorism Justify The Use Of Force?, Joanna Siekiera
Lawfare And Terrorism – Can Terrorism Justify The Use Of Force?, Joanna Siekiera
Graduate Research Conference (GSIS)
As the world became increasingly interconnected, the significance of international law has been augmented exponentially. International law encompasses a vast array of legal systems, written norms, and customary principles that govern the interactions between states, still being the primal and main norm creators, as well as to some extent international organizations, and other non-state actors (NSA) gaining more and more influence, and finally us - individuals. In recent times, the utilization of law as a tool of warfare has gained prominence, with public and private entities leveraging legal arguments and international institutions to achieve their military and political objectives. While …
The Post-Millennial French Colonial Empire, Chase Plante
The Post-Millennial French Colonial Empire, Chase Plante
Graduate Research Conference (GSIS)
The French Colonial Empire of the Age of Imperialism was born in the apocalyptic fires of a millennial movement: the French Revolution of 1789. Millennial movements aspire to rapidly, often violently, achieve utopia by transforming their contexts. Revolutionary France went to war to liberate the world from tyranny and so began both French nationalism and the resurged French colonial empire. The crusade failed, but nationalism and imperial expansion remained. The French genuinely believed that, in their imperial and colonial expansion and domination, they were bringing the world closer to utopia. Assimilation, linguistic and cultural, was a key part of this. …
Beyond The Institution Of Motherhood: Shifting The Paradigm, Gabrielle Wilson
Beyond The Institution Of Motherhood: Shifting The Paradigm, Gabrielle Wilson
Graduate Research Conference (GSIS)
This paper explores declining birth rates as a global act of resistance and reclamation by women and birthing individuals against hyper-masculinized institutions, using South Korea's 4B movement as a case study. The 4B movement, which rejects marriage, childbirth, romance, and heterosexual relationships, represents a paradigm shift challenging entrenched gender norms, state control, and systemic inequities. It exemplifies a global phenomenon as similar movements gain traction in the U.S., Japan, and beyond, amidst rising conservatism and declining fertility rates. Framing this analysis with intersectionality, Feminist IR theory, and Kuhn’s paradigm shift model, the paper argues that this resistance signifies a transformative …
Modeling The Impact Of Nato Policy Actions On Taliban Disinformation Campaigns With Lotka-Volterra Models, Timothy Tarter, Bella Santos
Modeling The Impact Of Nato Policy Actions On Taliban Disinformation Campaigns With Lotka-Volterra Models, Timothy Tarter, Bella Santos
Graduate Research Conference (GSIS)
In this paper, we use an adaptation of the Lotka-Volterra Predator-Prey framework (via Affilit Et. Al.) to model the relationship between Taliban disinformation campaigns and NATO’s attempts to counter them. We find that aggression is a significantly preferred strategy over stagnation; this result should prompt decisionmakers to take strong stances against disinformation campaigns while maintaining a healthy defense against retribution. This leads us to propose the NATO Afghan Youth for Change program, which provides scholarships to individuals throughout the Afghan diaspora to become NATO influencers - a role which will both advance their personal goals and mitigate the spread of …
Research In Indigenous Historiographies: Oral History As Evidence For Federal Recognition Of Indian Tribes, Colette Haworth
Research In Indigenous Historiographies: Oral History As Evidence For Federal Recognition Of Indian Tribes, Colette Haworth
Graduate Research Conference (GSIS)
Significant to the field of cultural studies is the identification of cultural artifacts, which enable scholars to analyze the complexities of societies, comprehend cultural dynamics, and investigate the ways in which individuals and communities construct meaning and identity in cultural contexts. Oral history, an intangible cultural artifact, has been an important cultural identifier, particularly for marginalized individuals and communities. The development of critical oral history (COH) methodology has alleviated some of the criticism toward oral history as a valid methodology. In fact, some scholars contend that COH has moved beyond the realm of academic research to “provide a policy relevant …

Public Surveillance And Human Rights: The Chilling Effect Of Surveillance Technologies And Legal Debates In Europe, Anna Calabrese
Graduate Research Conference (GSIS)
The rapid advancement and intense deployment of surveillance technologies pose a profound threat to fundamental human rights and render the balance between national security and rights and freedoms guarantees even more challenging. This paper interrogates the menace that digital tracking such as IMSI-catchers and other sophisticated tools represent to contemporary democracies with a specific focus on their potential to introduce a “chilling effect” to deter individuals in political and social communities from exercising their freedoms of speech, expression, association, thereby endangering the core values of all democracy. This analysis offers an overview of the state-of-the-art in Europe and highlights recent …
From Shatter Zone To Shatterbelt: The Role Of The Three Seas Initiative In Shaping Central And Eastern Europe, Ian Murphy
Graduate Research Conference (GSIS)
The Three Seas Initiative (TSI) is a relatively new political and economic platform aimed at enhancing connectivity and infrastructure development in Central and Eastern Europe (CEE). This initiative seeks to address the region’s historical underdevelopment and lack of north-south connectivity. This paper examines the role of the TSI in the context of a changing geopolitical landscape, where Russia and China are increasingly seeking to exert influence. The central research question is: Does the TSI represent a fundamental shift in the CEE region, and how can it foster interdependence while mitigating the risk of conflict? I argue that the TSI signifies …
Soft Law, Activism, And Climate Displacement: Rethinking International Protections For The Environmentally Displaced, Guljannat Huseynli, Andrea G. Brown
Soft Law, Activism, And Climate Displacement: Rethinking International Protections For The Environmentally Displaced, Guljannat Huseynli, Andrea G. Brown
Graduate Research Conference (GSIS)
Climate change is displacing millions of people globally, yet those forced to migrate due to environmental factors remain unprotected under existing international refugee law. This paper argues that legal recognition for climate refugees can emerge not through immediate treaty reform but through the evolution of soft law and norm creation. Drawing on constructivist theory, it examines how activism, international organizations, and legal precedents contribute to shifting global norms. Through case studies such as Ioane Teitiota v. New Zealand and the Fridays for Future movement, the paper shows how strategic litigation and advocacy can build momentum for future legal protections. It …

Embedding And Enabling Multi-Domain Combat Capabilities With Partners And Allies: A Joint Concept Proposal, Nathan Colvin, Aljoša Kaučevič, Randall Mercer
Graduate Research Conference (GSIS)
Future military operations will rely upon a coalition partnership’s ability to conduct regional and global operations across all domains. Currently the US has the most robust multi-domain skill sets of any existing military force, but the US cannot be solely responsible for operations around the globe. To do so would be geopolitically and economically infeasible. An answer may be to build cohesive coalition force units capable of combining localized capabilities and specialized US global competencies. The ability to respond to any type of threat through the synergy of coalition strengths will act to deter regional threats throughout the cooperation, competition, …

Neonatal Outcomes In Periviable Births Weighing ≤ 500 Grams, Bijan Morshedi, Diego Maurente, Ursula Griffiths-Randolph, Elisabeth Kamano, Katharine Hopkins, Dana Baraki, Juliana Martins, Steven Warsof
Eastern Virginia Medical Journal
Background: The average rate of preterm birth in the US in 2021 was 10.1%. Although the rate of mortality from preterm birth has been decreasing, complications remain the leading cause of death in infants under the age of 5 years worldwide. Gestational age (GA) and birth weight (BW) remain the 2 most important variables for predicting survivability in preterm births, and lower GA and BW are both correlated with lower survivability.
Objective: To explore outcomes of neonates born in the periviable period (20 weeks and 0 days to 25 weeks and 6 days) with BW ≤ 500 g and to …

Introduction: In the field of medical research, empirical Bayesian analysis has emerged as an increasingly applicable approach. This statistical framework offers greater flexibility, enabling researchers to incorporate prior information and rigorously estimate parameters of interest. However, the selection of suitable prior distributions can be a challenging endeavor, with profound implications for the resulting inferences. To address this challenge, this study proposes a new analytical procedure that leverages resampling techniques to guide the choice of priors in Bayesian analysis. Subject and Methods: The study group consisted of patients who had been diagnosed and had died of pancreatic adenocarcinoma (cause-specific death) who …
Rapid Prediction Of Coastal Flooding With Deep Neural Networks, Ali Shahabi, Navid Tahvildari
Rapid Prediction Of Coastal Flooding With Deep Neural Networks, Ali Shahabi, Navid Tahvildari
Graduate Student Government Association Research Conference
With the increasing impact of climate change and relative sea level rise, low-lying coastal communities face growing risks from extreme storm tides and recurrent nuisance flooding. Thus, timely and reliable predictions of coastal water levels are critical to resilience in vulnerable coastal areas. Over the past decade, enormous efforts have been made to utilize machine learning (ML) based data-driven models for the emulation and prediction of storm tides. However, flood advisory systems still rely on running computationally demanding real-time hydrodynamic models. because developing highly reliable ML-based models suitable for real-time forecasting and capable of capturing any surge levels is challenging. …
Zombie-Auras: Genai And Hybrid Text Production, Joshua Nieubuurt
Zombie-Auras: Genai And Hybrid Text Production, Joshua Nieubuurt
English Faculty Publications
This paper explores the iterative evolutions of textual production and their impact on the “aura” of texts, as conceptualized by Walter Benjamin. The study identifies three key phases of textual production: the natural, the mechanized, and the digitized, each progressively displacing the “cult value” of texts. This cult value is lost through increased ease of creation, reproduction, dissemination, and dislocation of creators and audiences in time and space. The advent of Generative AI (GenAI) marks the latest evolution, transforming the “aura” into a memetic “zombie” form—familiar yet opaque, evoking both the sublime and fear. By examining Benjamin’s notion of “aura” …

A Mixed-Method Analysis Of The News Media Framing Of Gender Non-Conforming Victims Of Homicide In The U.S. From 2012-2022., Susana Avalos, Hayley Jackey, Iyan Wickel
Graduate Student Government Association Research Conference
Recent analyses of transgender homicide victims find that the news media often uses improper terminology, delegitimizes, and victim blames them. These analyses, while insightful, are limited as they have largely analyzed cases involving trans women and trans feminine individuals. The present study employs a mixed method approach to analyze news media articles (N=88) published in U.S. online news media outlets about 17 gender non-conforming victims killed between 2012 and 2022. We found that most articles did not delegitimize or victim-blame. However, we find 1) victim blaming occurred when reporting on cases of officer-involved shootings, 2) certain victims receive more coverage …

Surveys are a core methodological tool in government, industry, and academia, providing essential data for theory development and evidence-based decision-making. As artificial intelligence continues its rapid advancement, it stands to fundamentally transform the entire survey lifecycle - from design and administration to analytics and reporting. Previous transitions to new technologies, such as telephone, internet, and non-probability surveys, led to divisions within the survey research community with real consequences for both the trajectory of research and trust in the industry. We believe the survey community should take proactive steps now to avoid similar challenges with AI integration. Specifically, our paper examines …

Engineering Management & Systems Engineering Faculty Publications
Per- and polyfluoroalkyl substances (PFAS) contamination has posed a significant environmental and public health challenge due to their ubiquitous nature. Adsorption has emerged as a promising remediation technique, yet optimizing adsorption efficiency remains complex due to the diverse physicochemical properties of PFAS and the wide range of adsorbent materials. Traditional modeling approaches, such as response surface methodology (RSM), struggled to capture nonlinear interactions, while standalone machine learning (ML) models required extensive datasets. This study addressed these limitations by developing hybrid RSM-ML models to improve the prediction and optimization of PFAS adsorption. A comprehensive dataset was constructed using experimental adsorption data, …

Feel Bad To Discard A Fashion Product: How Ai Designers Influence Individuals' Sustainable Consumption, Ha Kyung Lee, Dooyoung Choi
Feel Bad To Discard A Fashion Product: How Ai Designers Influence Individuals' Sustainable Consumption, Ha Kyung Lee, Dooyoung Choi
Educational Leadership & Workforce Development Faculty Publications
This study explores how AI technology in fashion design influences consumers' sustainable consumption behaviors, focusing on emotional attachment to products. By comparing AI-generated and human-designed fashion items, the study examines how designer type impacts negative emotions about discarding products, mediated by emotional attachment. Results from two experimental studies reveal that designer type significantly affects negative emotions toward discarding human-designed items, but emotional attachment was not influenced by designer type in the first study. This lack of difference may be due to personal characteristics that moderate the effect. The second study found that individuals who perceive AI as human-like form stronger …

The activity of nucleoside and nucleotide analogs as antiviral agents requires phosphorylation by intracellular enzymes. Phosphate-substituted analogs have low bioavailability due to the presence of ionizable negatively-charged groups. To circumvent this limitation, several prodrug approaches have been proposed and developed. Herein, we hypothesized that the conjugation of anti-HIV fatty acids with the nucleotide tenofovir alafenamide (TAF) (1) could improve the anti-HIV activity of the nucleotide. Several fatty acyl amide conjugates of TAF were synthesized and evaluated in comparative studies with TAF. The synthesized compounds were evaluated as racemic mixtures for anti-HIV activity in vitro in a single-round HIV-1 infection assay …

The capacity of temporal interference (TI) stimulation to target deep brain regions without affecting nearby surface electrodes remains uncertain. Using artifact-free optical recording, we compare excitation patterns and thresholds in hippocampal neurons stimulated by “pure” and amplitude-modulated sine waves, representing TI waveforms near electrodes and at the target, respectively. We show that pure 2- and 20-kHz sine waves induce repetitive firing at rates that increase up to 60–90 Hz with stronger electric fields. Beyond this limit, action potentials merge into sustained depolarization, resulting in an excitation block. Modulating the sine waves at 20 Hz aligns firing with amplitude “beats” and …
Background-Field Method And Qcd Factorization, Ian Balitsky
Background-Field Method And Qcd Factorization, Ian Balitsky
Physics Faculty Publications
One method for deriving a factorization for QCD processes is to use successive integration over fields in the functional integral. In this approach, we separate the fields into two categories: dynamical fields with momenta above a relevant cutoff, and background fields with momenta below the cutoff. The dynamical fields are then integrated out in the background of the low-momentum background fields. This strategy works well at tree level, allowing us to quickly derive QCD factorization formulas at leading order. However, to extend the approach to higher loops, it is necessary to rigorously define the functional integral over dynamical fields in …
