Executive Actions To Ensure Safe And Responsible Ocean Carbon Dioxide Removal Research In The United States, Romany M. Webb, Korey Silverman-Roati

Sabin Center for Climate Change Law

This paper presents recommended actions that federal agencies could take, under existing law, to ensure safe and responsible permitting and regulation of ocean carbon dioxide removal (CDR) research in U.S. waters. Controlled field trials and other in-ocean research is critical to improve scientific and societal understanding of ocean CDR techniques that could help the U.S. reach its climate goals. That could raise a host of legal issues, however. Existing legal frameworks were not designed to regulate ocean CDR, and federal agencies have yet to fully explain how decades-old environmental laws will be applied to a new set of activities.

This Has Not Happened: African American Performances At The Edge Of The Century, Andie Berry

Yale Graduate School of Arts and Sciences Dissertations

This dissertation articulates a relationship among sociopolitical crisis, speculation, and spectacle that emerges from the fiscal and social conservatism of the 1980s. I argue that, over the last four decades, theater presents a distinctive opportunity to push beyond politics of representation to an embodied mode of speculative thought. By analyzing the impossible longevity that ties together August Wilson’s American Century Cycle (1982-2005), the sonic inscrutability of the black body in Lisa Jones’s and Suzan-Lori Parks’s respective radio dramas Ethnic Cleansing (1993) and Loco-motive (1991), and the layers of transparency and opacity in Jackie Sibblies Drury’s stage plays Really (2016) and …

Features Selection In Regression Models Using Variance-Based Sensitivity Analysis, Jakob Spiller

Honors Theses

Variance-based sensitivity analysis serves as a crucial tool for assessing the variability of inputs on the output of complex mathematical models. In this thesis, we study Sobol indices, a class of variance-based sensitivity analysis, to quantify the importance of each input variable on the overall variability of the model output. We initially discuss Sobol’s first and total order indices. This includes a brief demonstration through two examples: the Sobol G-function and a polynomial function each with six input variables. These examples serve to highlight the theoretical foundations and practical applications of Sobol’s indices in analyzing model sensitivities. Mainly, we apply …

Differences In Dynamic Knee Valgus Using Kinesiology Tape In Female Athletes, Riley J. Williams

Honors Theses

Excessive dynamic knee valgus (DKV) is commonly known as improper alignment in the frontal plane combined with excessive hip adduction, internal rotation, and tibia external rotation (Besier, Gold, Delp, Fredericson, & Beaupré, 2008; Maykut, Taylor-Haas, Paterno, DiCesare & Ford, 2015). More specifically, DKV is a medial collapse of the knee resulting in a hip adduction and internal rotation, tibial abduction and medial knee displacement, which increases the ACL strain (Llurda-Almuzara et al., 2020). Namata et al. (2018), using a three-dimensional kinematic analysis, reported female athletes are more commonly known to obtain a greater knee valgus angle when participating in landing …

Estimating Direction Of Arrival For Multi-Arm Spiral Antennas Using Machine Learning, Samuel Pearson

Honors Theses

Military systems require monitoring a wide frequency range of the RF spectrum to detect and monitor enemy targets. A vital component of that is calculating the direction of arrival of enemy radars. The use of compressive sensing architectures like the Nyquist Folding Receiver (NyFR) allow for computationally cheap capturing of wideband signals; however, these techniques make traditional direction of arrival (DOA) estimation techniques difficult. Given the advantages of compressive sensing, this research aims to apply machine learning (ML) techniques to multi-arm spiral antennas to estimate the incoming DOA. Software like MATLAB was used to simulate the multi-arm spiral antenna and …

Remotely Sensed Imagery Reveals Animal Feeding Operations Increase Downstream Dissolved Reactive Phosphorus, Andrew G. Meyer, Zach Raff, Sarah Porter

Economics Faculty Research and Publications

In this paper, we use remotely sensed imagery to identify the location and size of animal feeding operations in the Maumee River Watershed, a key drainage area to Lake Erie's Western Basin, which has recently experienced severe harmful algal blooms. We then estimate the relationship between the intensity of animal feeding operations in the watershed and surface water body concentrations of dissolved reactive phosphorus (DRP), the pollutant most responsible for algal growth. We find that stream reaches with relatively larger increases in upstream animal feeding exposure experience significantly higher increases in concentrations of DRP. The average marginal upstream animal feeding …

Political Affirmative Action, Girardeau A. Spann

Georgetown Law Faculty Publications and Other Works

In the Supreme Court’s most recent affirmative action decision—Students for Fair Admissions, Inc. (SFFA) v. President & Fellows of Harvard College—the Court wrongly continued to believe that it has a role to play in determining the constitutionality of affirmative action. Where the Constitution lacks a legal standard that is sufficiently precise to provide meaningful constraint on the exercise of judicial discretion, questions concerning proper interpretation of that standard are what Marbury v. Madison deemed to be “in their nature political” and therefore “only politically examinable.” In such cases, the Constitution simply means what the political branches of government …

Constitutional Supremacy, Inherent Powers, And Orders That Damages Or Costs Be Paid In Instalments: Tan Meow Hiang V Ong Kay Yong [2023] Sghc 286, Benjamin Joshua Ong

Research Collection Yong Pung How School Of Law

The General Division of the High Court of Singapore stated (obiter) in Tan Meow Hiang v Ong Kay Yong that it does not have a general power to order that damages or costs be paid in instalments. It reasoned that any such power must have been impliedly restricted by legislation. So instalment orders can only be made (a) by certain subordinate courts; (b) by the General Division on appeal; (c) by the General Division at first instance in personal injury cases. In response, this note aims to advance the conversation on the law on instalment orders and what the Constitution …

Conceptualising State-Centric Mediation: An Analysis Of China's Foreign Investment Complaints Mechanism, Mark Mclaughlin

Research Collection Yong Pung How School Of Law

This article argues that China's foreign investor complaints system constitutes 'state-centric investment mediation'. The Rules on Handling Complaints of Foreign-Invested Enterprises, which entered into force on 1 October 2020, place a state agency in the position of facilitating negotiations between a foreign investor and the agency being complained against. The prospects for this complaints system depend on how the state-as-mediator dynamic is perceived by foreign investors. To this end, it will be argued that settlement agreements reached pursuant to this system may be enforceable under the Singapore Convention on Mediation in certain circumstances. Investors and government entities operating similar systems …

Topological Spaces Of Embodied Becoming: Queens, Queerness And (Infra)Structural Subterfuge In Singapore, Orlando Woods

Research Collection College of Integrative Studies

This paper considers the political potential that emerges when theorizations of the body-as-infrastructure are brought into conversation with theorizations of topological space. It argues that the infrastructural body provides an interface through which structural norms can be destabilized, and the interrelationships between the state, society, and self can be reimagined. These ideas are illustrated through an empirical exploration of drag queens in Singapore. Singapore is a socially conservative Asian city-state in which heteronormative values are passed down by the state, reproduced through the family, and then used to structure societal under- standings of gender and sexuality. By interpreting Singapore’s hegemonic …

3/5ths Of Freedom: The Analysis Of {With} Black Individuals In Higher Education And Navigating Society Post-Justice-Involvement, Gabrielle Sarah Smith Finnie

Educational Leadership & Workforce Development Theses & Dissertations

Black individuals have been disproportionately involved in the criminal justice system in the United States (Federal Bureau of Prisons, 2022). Because of their criminal justice involvement, Black individuals are perceived as second-class citizens making their quest for “freedom” an endless journey impacted by oppression and domination post-justice-involvement (Couloute & Kopf, 2018; Johnson, 2021; Pager, 2003). To combat domination and oppression, Freire (1970) emphasized pursuing higher education helps individuals who experience marginalization become more humanized and aids them on their plight to freedom. Research highlighted pursuing higher education post-justice-involvement is a liberatory yet challenging experience because of discriminatory on-campus …

Advancing Data-Driven Decision Making For Transportation Safety: Emerging Trends, Statistical Modeling, And Causal Inference, Guocong Zhai

Civil & Environmental Engineering Theses & Dissertations

Despite recent advances in data-driven decision-making for transportation safety, there remain potential biases in the decision-making for emerging trends (i.e., shared mobility, safe systems, vehicle electrification, and equity) in transportation. In that case, this dissertation aims to facilitate robust and equitable data-driven decision-making in transportation safety, addressing the potential biases: 1) spatial and inherent correlations across different types of crashes, 2) measurement error biases of exposures, 3) confounding biases, and 4) disparity biases in transportation safety.

To be more specific, four research objectives are demonstrated below. Chapter 3 assessed the safety performance of taxi and ride-hailing services by a multivariate …

Whom Do Prosecutors Protect?, Vida Johnson

Georgetown Law Faculty Publications and Other Works

Prosecutors regard themselves as public servants who fight crime and increase community safety on behalf of their constituents. But prosecutors do not only seek to protect those they are supposed to serve. Instead, prosecutors often trade community safety, privacy, and even the constitutional rights of the general public to enlarge police power. Prosecutors routinely advocate for weaker public rights, shield police from public accountability, and fail to prosecute police when they break the law.

This Article will show how prosecutors often protect police at the expense of the public. This Article suggests a novel theory of evaluating the conduct of …

Morrison’S Flawed “Focus” Test And The Transnational Application Of The (Misinterpreted) Wire Fraud Statute, Julie R. O'Sullivan

Georgetown Law Faculty Publications and Other Works

Federal prosecutors' mantra is “when in doubt, charge wire fraud.” Section 1343 can be applied to any scheme to defraud--a capacious term that encompasses everything from computer scams to bribery and smuggling--in which a wiring (by phone, text, internet communication, or the like) can be identified. Given the explosion of transborder criminality--especially that conducted by wire--the geographic scope of the statute is of great practical importance. This Article resolves a circuit split by applying the Supreme Court's presumption against extraterritoriality and concluding that nothing in § 1343 rebuts that presumption. It then attempts to answer the critical question of what …
