Efficient High Order Ensemble For Fluid Flow, John Carter

Doctoral Dissertations

"This thesis proposes efficient ensemble-based algorithms for solving the full and reduced Magnetohydrodynamics (MHD) equations. The proposed ensemble methods require solving only one linear system with multiple right-hand sides for different realizations, reducing computational cost and simulation time. Four algorithms utilize a Generalized Positive Auxiliary Variable (GPAV) approach and are demonstrated to be second-order accurate and unconditionally stable with respect to the system energy through comprehensive stability analyses and error tests. Two algorithms make use of Artificial Compressibility (AC) to update pressure and a solenoidal constraint for the magnetic field. Numerical simulations are provided to illustrate theoretical results and demonstrate …

Co2-Assisted Ethylene Production And Subsequent Purification: A Materials Development, Kinetic Assessment, And Process Performance Investigation, Khaled Baamran

Doctoral Dissertations

"This research focuses on the In-Situ CO₂ capture and utilization in the oxidative dehydrogenation of ethane (ODHE) for ethylene production, and a subsequent ethylene purification through adsorptive separation process. In particular, several dual-function materials (DFMs) were developed, formulated into 3D-structure, and investigated for ODHE reaction to ethylene under various process conditions using CO₂ as a mild oxidant. The DFMs materials were consisted of CaO and metal oxides (e.g., Cr₂O₃ and V₂O₅) supporting H-ZSM-5. The results indicated that higher cell densities lead to better performance due to kinetic enhancement, and the optimum …

Advances In Differentially Methylated Region Detection And Cure Survival Models, Daniel Ahmed Alhassan

Doctoral Dissertations

"This dissertation focuses on two areas of statistics: DNA methylation and survival analysis. The first part of the dissertation pertains to the detection of differentially methylated regions in the human genome. The varying distribution of gaps between succeeding genomic locations, which are represented on the microarray used to quantify methylation, makes it challenging to identify regions that have differential methylation. This emphasizes the need to properly account for the correlation in methylation shared by nearby locations within a specific genomic distance. In this work, a normalized kernel-weighted statistic is proposed to obtain an optimal amount of "information" from neighboring locations …

Near-Ir Spectroscopic Analysis Of The Primary Volatile Composition Of Long And Short-Period Comets, Younas Khan

Doctoral Dissertations

"Comets are among the most well-preserved objects that formed in the protosolar nebula ∼4.5 Gyr ago. Hence, they are important for understanding various aspects of the formation, evolution, and habitability of the solar system. Multiple primary volatiles (molecules directly sublimating into the coma from the nucleus) emit via rovibrational transitions in the near-IR, providing opportunities to calculate their abundances. To date, only ∼50 comets have been characterized for their primary volatiles, with the short-period Jupiter-family comets (JFCs) being significantly underrepresented. In contrast, hundreds of comets have been sampled at optical/UV wavelengths, primarily for the composition of daughter species, leading to …

Do Trap-Neuter-Return (Tnr) Practices Contribute To Human–Coyote Conflicts In Southern California?, Danielle M. Bucklin, Jennifer M. Shedden, Niamh M. Quinn, Robert Cummings, Paul Stapp

Human–Wildlife Interactions

One possible contributor to the unusually high number of conflicts between coyotes (Canis latrans) and people in urban southern California, USA, may be the abundance of free-roaming domestic cats (Felis catus; cats) subsidized by feeding and augmented by trap-neuter-return (TNR) programs. To determine if coyotes regularly prey on and consume cats, we combined visual and molecular-genetic approaches to identify prey items in stomachs of 311 coyotes from Los Angeles County and Orange County, provided to the South Coast Research and Extension Center, in Irvine, California, between June 2015 and December 2018. We detected cat remains in …

Habituated, Tolerant, Or Salt-Conditioned Mountain Goats And Human Safety, Richard B. Harris, Kurt Aluzas, Laura Balyx, Jami Belt, Joel Berger, Mark Biel, Tonya Chilton-Radandt, Steeve D. Côté, Julie Cunningham, Adam Ford, Patti Happe, Chad P. Lehman, Kim Poole, Clifford G. Rice, Kirk Safford, Wesley Sarmento, Laura Wolf

Human–Wildlife Interactions

Interactions between humans and wildlife include a number of consumptive and non-consumptive forms. In some cases, the increased demand for wildlife viewing can precipitate new human–wildlife conflicts. Mountain goats (Oreamnos americanus; goats) are native to a number of North American mountain ranges from southeastern Alaska to southwestern Montana, USA. Goat habitat typically consists of steep terrain and cold weather habitats, which has left them particularly vulnerable to climate change. Their alpine environments also make them vulnerable to disturbance by aircraft and land-based motorized human activity. We reviewed and characterized situations in which goats in close proximity to humans …

Conflict Animals, Or Conflict People—That Is The Question, Vincenzo Penteriani

Human–Wildlife Interactions

Managing conflictual sce­narios involving large carnivores is generally addressed from an animal-centric perspective. This is rather contradic­tory because such conflicts are mostly triggered by human conduct that acts on animal’s instinc­tive behaviors. Shifting conflict miti­gation perspectives to human behaviors may thus provide a more consistent management strategy than focusing only on animals. For example, human habituation and anthropogenic food conditioning are 2 main conflict drivers that mostly depend on human behavior. Thus, an approach that addresses the human dimension aspects of these conflicts needs to be reinforced. I offer 6 points to consider in prioritizing management to mitigate human–bear conflicts …

Falconer Perceptions Of, And Support For, Rabbit Hemorrhagic Disease Biosecurity Actions, Hannah G. Shapiro, Elizabeth F. Pienaar

Human–Wildlife Interactions

Rabbit hemorrhagic disease virus 2 (RHDV2) is a highly contagious virus that primarily infects wild and domestic rabbits and hares (lagomorphs). In the United States, state wildlife agencies rely on stakeholders to report RHDV2-related mortalities and engage in voluntary biosecurity actions to prevent the spread of RHDV2. However, stakeholder perceptions of RHDV2 and relevant biosecurity actions have not been evaluated. We conducted the first study in the United States on how falconers’ risk perceptions, knowledge, trust in state wildlife agencies to manage RHDV2, hunting behaviors, and demographic characteristics influenced their willingness to engage in voluntary biosecurity actions and support potential …

Navigating The Soviet Experiment: Travels And Writings Of John Dos Passos And Edmund Wilson In Soviet Russia, 1928-1935, Robert Allan Winslow

Graduate Student Theses, Dissertations, & Professional Papers

The travel accounts of Soviet Russia by John Dos Passos (1896-1970) and Edmund Wilson (1895-1972) vividly demonstrate how Western writer-travelers were drawn into Soviet cultural experiments. Only rarely was this process one of literary influence. This thesis focuses on published travel writings by Dos Passos (In All Countries, 1934) and Wilson (Travels In Two Democracies, 1936), as well as journals, letters, and essays, in terms of Soviet cultural developments both writers noted as historically significant in shaping Western views of the Soviet state, and of the methods involved in building socialism and Communism.

Reterritorialization And Enclavic Tourism Development: A History Of Zoning And Its Impacts In Corbett Tiger Reserve Landscape, India, Rajiv Bhartari

Graduate Student Theses, Dissertations, & Professional Papers

Zoning has become the sine qua non in protected area management around the world. Yet zoning as an assemblage of policies, practices and especially politics is not well understood, especially through a critical geographical/political ecology lens. In this research, I used the concepts of territorialization, reterritorialization and enclavization as a framework for examining the creation and impacts of zoning in the Corbett Tiger Reserve (CTR) landscape over past five decades (1973-2023). The Corbett Tiger Reserve landscape has the largest wild tiger (Panthera tigris tigris) population in any protected area in the world. The framework helped to understand successive …

Beliefs About False Allegations Of Sexual Violence: Intergroup Contact Theory And Rape Myth Acceptance At A Rocky Mountain University, Alexandra Marie Buscaglia

Graduate Student Theses, Dissertations, & Professional Papers

False allegations of sexual assault represent approximately 2% to 10% of all sexual assault allegations reported to law enforcement (Lisak et al., 2010). Despite this low prevalence rate, people tend to overestimate the occurrence of false allegations, and give false allegations excessive weight in arguments about rape myths and policy-making decisions. This excessive weight is given despite a lack of research evidence that false reports of sexual violence occur more frequently than those of any other crime (Ask, 2010; McMillan, 2018; Stabile et al., 2019). This overestimation is likely influenced by the overrepresentation and sensationalization of false allegations in the …

The Paradoxes Of A Unified Judicial Philosophy: An Empirical Study Of The New Supreme Court, 2020-2022, Victoria Frances Nourse

Georgetown Law Faculty Publications and Other Works

The 2021 Supreme Court Term ended with a bang, yielding blockbuster cases making headlines. But what of the rest of the cases? This is the first major paper to examine the “Trump effect,” meaning the influence of three Justices appointed by President Trump who all share a “unified” judicial philosophy. In a two-year project, starting from 2020, when Justice Barrett ascended to the Court, to the end of June 2022, this article reviews 124 cases and over 300 opinions. There is both good and bad news for the court’s new “unified” judicial philosophy. History and text are both upwardly mobile …

Ordinary Meaning And Ordinary People, Kevin Tobia, Brian G. Slocum, Victoria Frances Nourse

Georgetown Law Faculty Publications and Other Works

This Article considers the relationship between ordinary meaning and ordinary people in legal interpretation. Many jurists give interpretive weight to the law's ordinary meaning (i.e., general, nontechnical meaning). Modern textualists adopt a strong commitment to ordinary meaning and justify it by alluding to ordinary people: people understand law to communicate ordinary meanings. This Article begins from this textualist premise and empirically examines the meaning that legal texts communicate to the public. Five original empirical studies reveal that ordinary people consider genre carefully, and regularly take phrases in law to communicate technical legal meanings, not only ordinary ones. Building on the …

What Role For The Wto In Disciplining China’S State-Dominated Economy?, Jennifer A. Hillman

Georgetown Law Faculty Publications and Other Works

Is the World Trade Organization (WTO) and its rules-based system capable of addressing the distortions in trade caused by the explosive growth of China’s State-Owned Enterprises (SOEs)? If it is, why hasn’t it been put to use? If the WTO rules are not up to task, where and how do they need to be changed? Those are the questions that Henry Gao and Weihuan Zhou answer in their thorough and compelling assessment of the current state of China’s SOEs, the commitments China made when it joined the WTO and the relevance of the applicable WTO rules, Between Market Economy and …

International Investment Law In The Shadow Of Populism: Between Redomestication And Liberalism Re‐Embedded, Alvaro Santos

Georgetown Law Faculty Publications and Other Works

The international investment regime is in crisis, nowhere more so than in regard to the investor–state dispute settlement system. While several developing countries have been critical of the system for some time, rich countries like the US and EU states—once the principal promoters of this regime—are now acknowledging problems and advancing reforms. This change of position has been fueled by the mobilization of civil society and the emergence of domestic populist movements on both the right and the left, reflecting widespread discontent with the past three decades of neoliberal globalization and its effects on job losses, lower wages, and increasing …

Noticing Patents, John R. Thomas

Georgetown Law Faculty Publications and Other Works

Patents take the form of public letters that the U.S. Patent and Trademark Office (USPTO) actively disseminates. Whether these documents sufficiently provide the public with notice of the technologies they describe, as well as the proprietary rights that they assert, has been subject to long-standing debate. Many commentators conclude that patents are often filed too early in the research and development cycle, are deliberately drafted in a vague or obtuse manner, or are simply too numerous. As a result, identifying the relevant patent landscape is not just difficult for technology implementers, but possibly undesirable as a matter of innovation policy. …

Hatch-Waxman’S Renegades, John R. Thomas

Georgetown Law Faculty Publications and Other Works

No intellectual property rights impact society more forcefully than patents on pharmaceuticals. But as a practical matter, only a handful of jurists resolve disputes involving them. Two neighboring federal districts, Delaware and New Jersey, adjudicate the vast majority of patent contests between brand-name drug companies and generic manufacturers. And in contrast to Eastern Texas, which has been persistently derided as a renegade jurisdiction, the authority of the mid-Atlantic courts has seldom been questioned. The complex workings of the Hatch-Waxman Act, the compromise legislation that governs pharmaceutical patent litigation, go a long way to explaining such distinct shareholder reactions to highly …

Disrupting Data Cartels By Editing Wikipedia, Eun Hee Han, Amanda Levendowski, Jonah Perlin

Georgetown Law Faculty Publications and Other Works

Legal discourse in the digital public square is driven by memoranda, motions, briefs, contracts, legislation, testimony, and judicial opinions. And as lawyers are taught from their first day of law school, the strength of these genres of legal communication is built on authority. But finding that authority often depends on a duopoly of for-profit legal research resources: Westlaw and Lexis. Although contemporary legal practice relies on these databases, they are far from ethically neutral. Not only are these “data cartels” expensive-- creating significant access to justice challenges--they also are controlled by parent companies that profit by providing information to Immigration …

Beyond The Business Case: Moving From Transactional To Transformational Inclusion, Jamillah Bowman Williams

Georgetown Law Faculty Publications and Other Works

While workplace diversity is a hot topic, the extent to which the diversity management movement has effectively improved intergroup relations and reduced racial inequality remains unclear. Despite large investments in diversity and inclusion training and other company wide initiatives, historically excluded groups remain vastly underrepresented in leadership and the most lucrative careers, such as finance, law, and technology. This calls the efficacy of diversity, equity, and inclusion (DEI) efforts into question, particularly with respect to reducing racial inequality in the workplace.

This Article explains why it is time for organizational leaders to move beyond the transactional case for diversity and …

When The Digital Services Act Goes Global, Anupam Chander

Georgetown Law Faculty Publications and Other Works

The European Union’s Digital Services Act (“DSA”) establishes a “meta law”—public regulation of the private regulation conducted by internet platforms. The DSA offers an attempt to balance private technological power with democratic oversight. The DSA will likely prove an attractive model for other governments to assert control over massive global internet platforms. What happens when other countries borrow its approach, in an instantiation of the vaunted Brussels Effect? This Article evaluates the DSA using the “Putin Test”—asking what if an authoritarian leader were given the powers granted by the DSA? The Article argues that authoritarians might well exploit various mechanisms …

Advancing Racial Justice Through Civil And Criminal Academic Medical-Legal Partnerships, Yael Cannon, Vida Johnson

Georgetown Law Faculty Publications and Other Works

The medical-legal partnership (MLP) model, which brings attorneys and healthcare partners together to remove legal barriers to health, is a growing approach to addressing unmet civil legal needs. But MLPs are less prevalent in criminal defense settings, where they also have the potential to advance both health and legal justice. In fact, grave racial health inequities are deeply intertwined with both civil and criminal injustice. In both spheres, health justice is racial justice. Building on the experiences of the authors in their respective civil and criminal law school clinics at Georgetown University in Washington, D.C., this Article argues that academic …

Race And Entrepreneurship: Reclaiming Narratives, Priya Baskaran, Alicia E. Plerhoples

Georgetown Law Faculty Publications and Other Works

This essay makes the case for engaging in counter-narratives and inclusive storytelling within the transactional clinic curriculum. The authors leverage lessons from Critical Race Theory to amplify the voices and experiences of underrepresented entrepreneurs and marginalized communities in both clinic seminar and selected casework. In doing so, we challenge hegemonic narratives of entrepreneurship and expose our law students to the presence and impact of interlocking systems of subordination that minimize the existence and contributions of entrepreneurs of color. We challenge our law students and ourselves to become more creative and thoughtful lawyers to a more inclusive and diverse set of …

The Rule Of Law Under Challenge: The Enmeshment Of National And International Trends, Gregory Shaffer, Wayne Sandholtz

Georgetown Law Faculty Publications and Other Works

The goal of the rule of law is to protect individuals from the arbitrary exercise of power. Democracy and human rights depend on the rule of law. But today the rule of law is under growing threat in the United States and around the world. Trends regarding rule-of-law protections are transnational in scope. They involve shifting norms, institutions, and practices at the local, national, and international levels. This paper assesses how challenges are taking place at the international and national levels, and how these challenges are linked. It examines the ways in which international law and institutions are important for …

Abila Keynote Address: Beyond International Law? A Dangerous Time, Gregory Shaffer

Georgetown Law Faculty Publications and Other Works

In this keynote address for the 2023 International Law Weekend conference of the American Branch of the International Law Association (ABILA), I first address the dangers of the conference theme “beyond international law” at a time when challenges to international law and institutions increase and aim to constrain international law’s normative force. We have been here before. The world today recalls that of the interwar period, a time of growing economic insecurity and inequality that helped to catalyze the rise of authoritarian movements. During that period, Carl Schmitt was a leading legal theorist who eventually became a member of the …

Executive Branch Control Of Federal Grants: Policy, Pork, And Punishment, Eloise Pasachoff

Georgetown Law Faculty Publications and Other Works

High-profile controversies in each of the last several administrations have involved the extent of Executive Branch control over federal grants. These challenges were particularly pronounced during the Trump Administration, when it seemed that each month brought a new grant-related controversy, from the opening week’s attempts to withhold funding from sanctuary cities to the last months’ effort to deny funding to “anarchist” jurisdictions. The aftermath of the Trump Administration thus provides an important opportunity to assess the bounds of Executive Branch control over federal grants writ large. In doing so, this Article makes three contributions. First, as a descriptive matter, it …
