Show-Me Resilience: Assessing And Reconciling Rural Leaders’ Perceptions Of Climate Resilience In Missouri, Zachary J. Miller, Caleb O'Brien, Casey I. Canfield, Lauren Sullivan

Engineering Management and Systems Engineering Faculty Research & Creative Works

Rural areas of the United States play a vital role in coping with, adapting to and mitigating climate change, yet they often lag urban areas in climate planning and action. Rural leaders—e.g., policymakers, state/federal agency professionals, non-profit organization leadership, and scholars – are pivotal for driving the programs and policies that support resilient practices, but our understanding of their perspectives on climate resilience writ large is limited. We conducted semi-structured interviews with 23 rural leaders in Missouri to elucidate their conceptualizations of climate resilience and identify catalysts and constraints for climate adaptation planning and action across rural landscapes. We investigated …

Deep Reinforcement Learning For Approximate Policy Iteration: Convergence Analysis And A Post-Earthquake Disaster Response Case Study, Abhijit Gosavi, L. (Lesley) H. Sneed, L. A. Spearing

Engineering Management and Systems Engineering Faculty Research & Creative Works

Approximate Policy Iteration (API) is a Class of Reinforcement Learning (RL) Algorithms that Seek to Solve the Long-Run Discounted Reward Markov Decision Process (MDP), Via the Policy Iteration Paradigm, Without Learning the Transition Model in the Underlying Bellman Equation. Unfortunately, These Algorithms Suffer from a Defect Known as Chattering in Which the Solution (Policy) Delivered in Each Iteration of the Algorithm Oscillates between Improved and Worsened Policies, Leading to Sub-Optimal Behavior. Two Causes for This that Have Been Traced to the Crucial Policy Improvement Step Are: (I) the Inaccuracies in the Policy Improvement Function and (Ii) the Exploration/exploitation Tradeoff Integral …

Objective: We test the effects of three aids on individuals' ability to detect social bots among Twitter personas: a bot indicator score, a training video, and a warning. Background: Detecting social bots can prevent online deception. We use a simulated social media task to evaluate three aids. Method: Lay participants judged whether each of 60 Twitter personas was a human or social bot in a simulated online environment, using agreement between three machine learning algorithms to estimate the probability of each persona being a bot. Experiment 1 compared a control group and two intervention groups, one provided a bot indicator …

Approximation Of Optimal Control Surfaces For The Bass Model With Stochastic Dynamics, Gabriel Nicolosi, Christopher Griffin

Engineering Management and Systems Engineering Faculty Research & Creative Works

The Bass diffusion equation is a well-known and established modeling approach for describing new product adoption in a competitive market. This model also describes diffusion phenomena in various contexts: infectious disease spread modeling and estimation, rumor spread on social networks, prediction of renewable energy technology markets, among others. Most of these models, however, consider a deterministic trajectory of the associated state variable (e.g., market-share). In reality, the diffusion process is subject to noise, and a stochastic component must be added to the state dynamics. The stochastic Bass model has also been studied in many areas, such as energy markets and …

Improved Quantification Of Defect Cross-Section For Active Microwave Thermography, Logan M. Wilcox, Kristen M. Donnell

Electrical and Computer Engineering Faculty Research & Creative Works

Active microwave thermography (AMT) is an integrated nondestructive testing and evaluation (NDT&E) technique that features a microwave-based excitation and subsequent thermographic inspection via an infrared camera. AMT has been successfully employed in several industries including aerospace and civil for NDT&E inspections. Since the excitation is microwave-based, an antenna is used to irradiate the sample under test and hence the heating pattern will vary spatially (following the antenna pattern). This nonuniform thermal excitation may limit the ability of AMT to quantify defect cross-sections. Therefore, this work seeks to expand the capabilities of AMT by incorporating a post-processing technique to improve defect …

Optimal Adaptive Tracking Control Of Partially Uncertain Nonlinear Discrete-Time Systems Using Lifelong Hybrid Learning, Behzad Farzanegan, Rohollah Moghadam, Sarangapani Jagannathan, Pappa Natarajan

Electrical and Computer Engineering Faculty Research & Creative Works

This article addresses a multilayer neural network (MNN)-based optimal adaptive tracking of partially uncertain nonlinear discrete-time (DT) systems in affine form. By employing an actor–critic neural network (NN) to approximate the value function and optimal control policy, the critic NN is updated via a novel hybrid learning scheme, where its weights are adjusted once at a sampling instant and also in a finite iterative manner within the instants to enhance the convergence rate. Moreover, to deal with the persistency of excitation (PE) condition, a replay buffer is incorporated into the critic update law through concurrent learning. To address the vanishing …

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 …

Tradeoffs May Counteract Effects Of Telecommunication Towers On Osprey Nesting, Gage R. Barnes, Kate G. Slankard, John B. Hewlett, Andrea K. Darracq

Human–Wildlife Interactions

The number of telecommunication towers (TCTs) throughout the United States has and continues to increase exponentially. Increased TCT placement has been implicated in local population increases in platform nesting birds such as ospreys (Pandion haliaetus). However, osprey use of artificial structures can cause conflicts with humans because of economic costs and risks to human safety. Managers require better information regarding the effect of artificial nesting surfaces, such as TCTS, on osprey reproduction to make informed decisions regarding species conservation and to mitigate potential conflicts. The objective of our study was to evaluate the influence of TCTs on osprey …

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 …

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 …

An Unmanned Aircraft System For Marking Live Power Lines To Prevent Bird Collisions, Mattheuns D. Pretorius, Lourens Leeuwner, Kaajial Durgapersad, Constant Hoogstad, Peter Beckedahl, Michael D. Michael, Kishaylin Chetty

Human–Wildlife Interactions

Collisions with overhead power lines represent a significant cause of mortality for a number of large bird species worldwide. Certain threatened species are severely impacted by power line collisions, particularly those for which there are no other known significant threats. In South Africa, bird collisions with overhead power line cables, including collisions with phase conductors and shield wires, contribute significantly to annual threatened bird species mortalities associated with Eskom power lines. The most practical mitigation measure is to attach bird anti-collision devices as markers on the cables. Current marking methods involve installations by hand, where linemen are hoisted up to …

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.

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 …

Effects Of Growth Factor Deprivation On Mkn-45 Spheroid Cells, Özlem Türksoy, Gökhan Terzi̇oğlu

Turkish Journal of Biology

Background/aim: Serum and growth factor deprivation, a common cellular stressor in solid tumors, arises upon irradiation, chemotherapy, and antiangiogenesis. Spheroid body culture aims to enrich cancer stem cells by using low attachment conditions and some growth factors, such as basic fibroblast growth factor and epidermal growth factor to support the spheroid formation in serum-free spheroid culture. However, spheroid culture without any growth factors can imitate the tumor environment more realistically. In this study, we aimed to identify the effect of growth factor deprivation on the MKN-45 gastric cancer cell line in terms of stemness characteristics. Materials and methods: The spheroids …

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 …

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 …

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 …

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 …

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 …

A Logical Proof That The Common Good, Not Economics, Underlies Copyright, Michelle M. Wu

Georgetown Law Faculty Publications and Other Works

Copyright experts endlessly debate its purpose: economic or common good. Both sides cite to judicial language backing their interpretations, and the frequency and cost of litigation between those representing the two interests have noticeably increased over recent years.

This article aims at a simpler way to resolve the dispute, by taking a step back and starting with the definition of a government. The government of a democratic republic, particularly one described as “of the people, by the people, and for the people,” has a single purpose: to address the common concerns of its people.

The following philosophical argument is a …

Martyrdom And Criminal Defense, Abbe Smith

Georgetown Law Faculty Publications and Other Works

According to research on the emotional well-being of lawyers, public defenders may be among the happiest. This comports with my own anecdotal experience as a teacher and mentor of law students and post-graduate fellows interested in criminal defense, many of whom are now career defenders. They may be deeply frustrated by the system in which they work, but they are happy to do what they can to make a difference for their clients. They also adore their defender colleagues. My former students and fellows in large law firms don’t seem quite as happy.

Notwithstanding the data, there seems to be …

Leveraging Academic-Medical Legal Partnerships To Advance Health Justice, Vicki W. Girard, Yael Cannon, Deborah F. Perry, Eileen S. Moore

Georgetown Law Faculty Publications and Other Works

Unmet legal needs contribute to housing, income, and food insecurity, along with other conditions that harm health and drive health inequity. Addressing health injustice requires new tools for the next generations of lawyers, doctors, and other healthcare professionals. An interprofessional group of co-authors argue that law and medical schools and other university partners should develop and cultivate Academic Medical-Legal Partnerships (A-MLPs), which are uniquely positioned to leverage service, education, and research resources, to advance health justice.
