Advisor responsiveness and GSA leadership correlated with wellbeing and academic engagement in bivariate analyses but were not …

Fpdclustering: A Comprehensive R Package For Probabilistic Distance Clustering Based Methods, Cristina Tortora, Francesco Palumbo

Faculty Research, Scholarly, and Creative Activity

Data clustering has a long history and refers to a vast range of models and methods that exploit the ever-more-performing numerical optimization algorithms and are designed to find homogeneous groups of observations in data. In this framework, the probability distance clustering (PDC) family methods offer a numerically effective alternative to model-based clustering methods and a more flexible opportunity in the framework of geometric data clustering. Given nJ-dimensional data vectors arranged in a data matrix and the number K of clusters, PDC maximizes the joint density function that is defined as the sum of the products between the distance and the …

Improving Field Education For Social Work In Vietnam: Intern Supervisors’ Perspectives Of The Current State And Potential Solutions, Megan Aikawa, Meekyung Han, Trang T. Nguyen, Linh Dinh, Minh Thanh Bui

Faculty Research, Scholarly, and Creative Activity

Research has identified challenges associated with the implementation of competency-based social work field education in Vietnam. However, there is limited information available from intern supervisors, who have unique perspectives at the crux of social work training and service delivery. An exploratory phenomenological qualitative approach was used to explore their experiences and perceptions through online interviews. Four categories were identified: diverse implementation of a common framework, rudimentary expectations and activities, challenges to implementation, and opportunities for improvement. These findings suggest that a multidimensional approach is needed, including improved collaborations between field agencies and universities to empower students, intern supervisors, and faculty.

Incorporating Uas Traffic Management Into Wildland Firefighting Operations: Initial Findings Of Subject Matter Expert Interviews, Deborah L. Bakowski, Lynne Martin, Gil Dustin, Chris Mariano

Faculty Research, Scholarly, and Creative Activity

Uncrewed Aircraft Systems (UASs) are being utilized throughout the disaster and emergency response domain, including in wildland firefighting operations. While UASs can offer safety benefits in comparison to crewed aircraft, such as removing the human pilot from the vehicle so that they are not exposed to the same risks and the ability to operate in low-visibility conditions, they are not without tradeoffs. For example, it can be challenging for UAS pilots (UASPs) to build situation awareness of the airspace in which their UAS is operating. In order to address some of the challenges associated with using UASs and provide greater …

Contextualizing Renewable Energy Adoption: An Examination Of The Role Of Community Choice Aggregation, Ankit Agarwal

Doctoral Dissertations

"The rapid expansion of renewable energy generation in the U.S., both through distributed and utility-scale facilities, is largely driven by top-down policy measures and the growing engagement of residential consumers on both individual and community levels. Previous studies on motives behind residential renewable energy adoption have examined procurement options in isolation and within a static context, primarily focused on intrinsic attributes like economic incentives, emission reductions, and peer popularity. This research introduces a novel context, assessing renewable procurement options in the presence of Community Choice Aggregation (CCA), a more prevalent and accessible alternative. This dissertation makes four pivotal contributions, offering …

Advanced Mass Spectrometry Method Development And Applications For Assessment Of Traumatic Brain Injury And Legionella Pneumophila Dissinfection With Copper, Austin Chase Sigler

Not Just Bony Fish: All Nonmammalian And Nonavian Animals Are Neglected In Both Welfare And General Research, Jennifer A. Mather Ph.D.

Animal Sentience

The lack of research on fish welfare highlighted by Oldfield & Bonano (2024) is only part of a more general problem: a relative neglect of animals other than mammals and birds. The causes are our lack of knowledge, our negative view of what we consider to be “lower” animals and our underestimation of their intelligence and sensitivity. Our estimation will increase as our knowledge increases. As a broader view spreads to the public through the media, it should gradually increase the demand to expand both research and welfare, especially beyond mammals and birds.

Mandatory Anti-Bias Cle: A Serious Problem Deserves More Meaningful Response, Rima Sirota

Georgetown Law Faculty Publications and Other Works

This essay addresses the problematic convergence of two recent trends: (1) the expansion of jurisdictions requiring anti-bias training (ABT) as part of mandatory continuing legal education (CLE), and (2) the growing recognition among social scientists that such training, at least as currently practiced, is of limited effectiveness.

Forty-six American states require continuing legal education (CLE), and eleven of these states now require lawyer ABT as one facet of CLE requirements. I have previously criticized the mandatory CLE system because so little evidence supports the conclusion that it results in more competent lawyers. The central question tackled by this essay is …

The Taylor Swift Effect And International Law, Katrin Kuhlmann

Georgetown Law Faculty Publications and Other Works

Taylor Swift’s Eras Tour has come to an end, but the Taylor Swift Effect will remain a powerful force with influence well beyond even Swift herself. Often used to describe Swift’s economic impact through her fandom, it has become shorthand for the broader network effect that amplifies and extends the reach of her discography and cultural influence. As this article discusses, the Taylor Swift Effect has real implications for international relations and international law at a time when many nations are withdrawing from constructive international engagement, with devastating consequences in terms of global rights, liberties, and norms.

This article explores …

Loper Bright In A Larger Interpretive Perspective: Is This Justice Scalia’S Court Anymore?, Victoria Frances Nourse

Georgetown Law Faculty Publications and Other Works

Loper Bright Enterprises v. Raimondo has left administrative lawyers agog: Could the Supreme Court really reverse the “goliath” known as Chevron deference? For those who study the Court’s interpretive landscape more broadly, however, Chevron reversal may not be as unexpected as administrative lawyers believe. This Article will look at Loper Bright by linking three notable interpretive developments: the major questions doctrine, Chevron skepticism, and strict constructions of statutory text. These developments share the same risk: the Court is imposing a new “clarity tax” on both Congress and administrative agencies. Having said this, others’ grave worries about changes in Chevron are …
