Deportations And Latino Segregation: The Residential Impacts Of Interior Immigration Enforcement, Matthew Hall, Jacob S. Rugh, Hao Liang
Deportations And Latino Segregation: The Residential Impacts Of Interior Immigration Enforcement, Matthew Hall, Jacob S. Rugh, Hao Liang
Faculty Publications
The shift of immigration enforcement to local jurisdictions has intensified localized patterns of anti-immigrant sentiment, enabling the system of mass deportation to expand at an unprecedented scale. This study examines the effects of 287 (g) agreements, which empower local law enforcement to enforce immigration laws, on Latino residential segregation. Using a quasi-experimental design that compares counties implementing 287 (g) with those that applied but did not implement, we find that these policies significantly slowed declines in Hispanic-white segregation, particularly in early-adopting Southern counties where enforcement was most aggressive. We find no evidence that the program altered patterns of segregation for …

Colleges of health, human sciences, and education are often administratively organized to include a diverse array of human sciences departments that share roots in social justice and a commitment to advancing equity and inclusion. Despite espoused commitments to equity and inclusion, they frequently struggle to achieve the changes necessary for advancing equity, and inclusion principles across policies, practices, procedures, and units. We implemented and evaluated a 7-day, total immersion, 56-h, educational program entitled the “Social Justice Institute” (SJI) for two cohorts of faculty, staff, and administrators to develop self-efficacy to intervene in systemic oppression in their academic units. SJI delivered …

This study demonstrates the 100 g scale manufacture of a plutonium alloy that ages at an accelerated rate. The resulting alloy ages six times faster than typical weapons-grade plutonium due to the addition of 238Pu. As a major innovation, the process involved using a partial direct oxide reduction technique. This method was achieved by developing a new, complex geometry stirrer using additive manufacturing to reduce the 238Pu oxide and efficiently incorporate it into weapons-grade plutonium metal. The material was then purified by molten salt extraction and electrorefining before being alloyed with gallium. The alloy was then cold-rolled and …

Methods For Rotating Electrodes In High-Temperature Molten Salts, Ranon Fuller, Eloise Cluff, Edward Mercado, Carlos Mejia, Devin Rappleye
Faculty Publications
In this paper, we describe and validate a custom apparatus for performing high-speed (250-3,500 rpm) rotating electrode and dilatometer density experiments in molten salts. The reported details can aid in decreasing the difficulty and increasing the quality of such experiments. We discuss the design challenges and the solutions identified. We investigate methods for accurately measuring the solution resistance using electrochemical impedance spectroscopy (EIS), calculating the working electrode area using cyclic voltammetry (CV), and measuring the mass transfer-limited current of rotating electrodes using a series of chronoamperometry (CA) pulses. We further demonstrate the efficacy of our methods in producing accurate results.

Delafossites, composed of noble metal (A+) and strongly correlated sublayers (BO2-), form natural superlattices with highly anisotropic properties. These properties hold significant promise for various applications, but their exploitation hinges on the successful growth of high-quality thin films on suitable substrates. Unfortunately, the unique lattice geometry of delafossites presents a significant challenge to thin-film fabrication. Different delafossites grow differently, even when deposited on the same substrate, ranging from successful epitaxy to complete growth suppression. These variations often lack a clear correlation to obvious causes like lattice mismatch. Unidentified stabilization mechanisms appear to enable growth in certain …

A series of boron dipyrromethene (BODIPY) dyes were nitrated in high yields using nitronium tetrafluoroborate at positions 2, 3, and 2,6 of the BODIPY core. This method allows for the regioselective nitration of the pyrrolic positions under milder conditions than previously reported methods. The photophysical properties and electronic transitions of these BODIPYs were investigated by using UV-vis spectroscopy, fluorescence spectroscopy, and density-functional theory (DFT) calculations. The introduction of one nitro group dramatically increases the dipole moment of the molecule, induces marked blue shifts in the absorption and emission bands, decreases the molar absorptivity, and increases the Stokes shifts of the …

Effect Of Precursors On Trimetallic Ruthenium-Based Catalysts Supported On Γ‑Al2O3 Pellets For Low-Temperature Ammonia Decomposition, Christopher J. Koch, Jennifer Naglic, Logan Kearney, Daniel Clairmonte, Binod Rai, Jochen A. Lauterbach, Lucas M. Angelette, Tyler Guin
Faculty Publications
Ammonia is a promising candidate as a liquid hydrogen energy storage medium, but it requires catalytic decomposition (ammonia cracking) to regenerate hydrogen. Recently developed trimetallic ruthenium−potassium-promoter (RuKM) ammonia decomposition catalysts have exceptionally low ammonia decomposition temperatures, able to perform the decomposition as low as 250 °C, which is significantly lower than other known catalysts that require temperatures above 500 °C. However, the effects of the RuKM precursor on the catalytic activity have not been investigated. We report the observed differences of 3% ruthenium/12% potassium/1% yttrium (RuKY) catalysts on γ-alumina synthesized from chloride-, nitrate-, and acetate-based precursors. Catalysts synthesized from chloride-based …

Anchoring ‘Neo-Hahnian Outdoor Education’ In The Cold War Era: A History Of Character Building In The Outward Bound Movement, Jayson Seaman
Faculty Publications
The invitation to comment on a foundational early article from the JAEOL provided a welcome opportunity to engage with Andrew Brookes’s trilogy of ‘neo-Hahnian outdoor education’ critiques (Brookes, 2003a, 2003b, 2023). In this article, I approach outdoor education’s character building ideology by using archival and secondary sources to situate its evolution in four periods corresponding with major geopolitical and cultural movements: (1) 1941–1945 when Outward Bound (OB) was established; (2) 1946–1952 when Hahn exported OB from his perch at Gordonstoun; (3) 1953–1967 when OB expanded to the U.S. and replicated globally, and (4) 1968–1976 when human potentialism replaced muscular Christianity …

Displaced Decarbonization: Climate Necropolitics And The Contested Spatialities Of Green Hydrogen In Namibia, Meredith J. Deboom
Faculty Publications
Green hydrogen is often presented as a transformative solution to the dual challenges of decarbonization and economic development. This article applies the framework of climate necropolitics to interrogate the contested spatialities underlying such “win-win” narratives. It does so through an extended case study of Hyphen Hydrogen Energy, a $10 billion green hydrogen project planned for Lüderitz, Namibia. A remote town of 20,000 in a country with a $12 billion annual GDP, Lüderitz initially appears to be an unlikely host site for the “industrial fuel of the future.” To explain this outcome, I first illustrate how discordant socio-spatial projects—including European energy …

Turbidity currents, which are stratified, sediment-laden bottom flows in the ocean or lakes, can run out for hundreds or thousands of kilometres in submarine channels without losing their stratified structure. Here, we derive a layer-averaged, two-layer model for turbidity currents, specifically designed to capture long-runout. A number of previous models have captured runout of only tens of kilometres, beyond which thickening of the flows becomes excessive, and the models without a lateral overspill mechanism fail. In our framework, a lower layer containing nearly all the sediment is a faster, gravity-driven flow that propels an upper layer, where sediment concentration is …

Researchers studying outdoor experiences for educational or recreational purposes will benefit from better capturing the environmental values of the individuals and communities they serve, as both antecedent predictors and outcome measures. The Kellert-Shorb Biophilic Values Indicator (KSBVI) is an instrument that has shown promise as a tool for assessing environmental values. However, the length of the KSBVI makes it impractical to use, especially in field settings where brief measures are desirable. Therefore, this study’s purpose was to explore environmental values in a college student population relative to Kellert’s (2002) typology and to reduce the KSBVI to a more …

We collected and analyzed an array of biosignals (face electromyogram, skin electrodermal activity, peripheral temperature, and electrocardiogram) in 60 participants with and without misophonia, a condition characterized by decreased tolerance to innocuous sounds. Our goal was to objectively characterize the physiological response to misophonia triggering sounds. We found that misophonic responses can be objectively identified in some cases through atypical physiological reactions to triggering stimuli, though not all participants exhibited this response. Our analyses suggest a large interindividual variability in response to misophonic triggers and highlights the need for methodological adjustments in future experiments to increase the detectability of misophonic …

Analyzing ultrasonic vocalizations (USVs) is crucial for understanding rodents' affective states and social behaviors, but the manual analysis is time-consuming and prone to errors. Automated USV detection systems have been developed to address these challenges. Yet, these systems often rely on machine learning and fail to generalize effectively to new datasets. To tackle these shortcomings, we introduce ContourUSV, an efficient automated system for detecting USVs from audio recordings. Our pipeline includes spectrogram generation, cleaning, pre-processing, contour detection, post-processing, and evaluation against manual annotations. To ensure robustness and reliability, we compared ContourUSV with three state-of-the-art systems using an existing open-access USV …

Deep Jansen-Rit Parameter Inference For Model-Driven Analysis Of Brain Activity, Deepa Tilwani, Christian O'Reilly
Faculty Publications
Accurately modeling effective connectivity (EC) is critical for understanding how the brain processes and integrates sensory information. Yet, it remains a formidable challenge due to complex neural dynamics and noisy measurements such as those obtained from the electroencephalogram (EEG). Model-driven EC infers local (within a brain region) and global (between brain regions) EC parameters by fitting a generative model of neural activity onto experimental data. This approach offers a promising route for various applications, including investigating neurodevel- opmental disorders. However, current approaches fail to scale to whole-brain analyses and are highly noise-sensitive. In this work, we employ three deep-learning architectures—a …

Fat activism is a movement that seeks to acknowledge and eliminate the oppression of fat people. The movement and those who participate face significant backlash, yet fat activism is understudied. We sought to understand lay theories about fat activism; that is, how everyday people think about the goals and motivations of fat activism, and people who engage in fat activism, to understand how these perceptions shape support for and backlash toward fat activism. In Study 1 (N = 294), we qualitatively elucidated lay theories of fat activism in a US nationally representative sample. We identified lay theories that both …

Purpose: Determine the impact of a 6-week YouTube-instructed bodyweight interval training (BW-IT) program on cardiometabolic health, muscular strength, and factors related to exercise adherence in adults with obesity. Methods: Fourteen adults (30.7 ± 10.3 yrs, BMI 35.5 ± 5.4 kg/m2) participated in this study. The BW-IT program progressed bi-weekly from a 1:3 to 1:1 work-to-rest ratio, using maximum effort intervals of high knees, squat jumps, scissor jacks, jumping lunges, and burpees. Pre- and post-intervention measures included peak oxygen consumption ( (Formula presented.) O2peak), relative quadriceps isometric muscular strength, waist circumference (WC), body composition via bioelectrical impedance, and cardiometabolic …

The goal of this sabbatical research is to learn more about non-Western ways of knowing and learning (epistemologies) and to become a more effective culturally responsive teacher. I investigated how Indigenous Knowledge and research practices can enrich current definitions and practices of Information Literacy and integrate them into the research process. Information Literacy is part of a larger and more complex research process that involves connecting researchers’ questions and purpose with literature reviews and the resulting new knowledge.
I am continuing my research journey that started with my dissertation work on Culturally Relevant Information Literacy and Critical Information Literacy (CIL). …

Understanding climate change impacts on global marine ecosystems and fisheries requires complex marine ecosystem models, forced by global climate projections, that can robustly detect and project changes. The Fisheries and Marine Ecosystems Model Intercomparison Project (FishMIP) uses an ensemble modeling approach to fill this crucial gap. Yet FishMIP does not have a standardised skill assessment framework to quantify the ability of member models to reproduce past observations and to guide model improvement. In this study, we apply a comprehensive model skill assessment framework to a subset of global FishMIP models that produce historical fisheries catches. We consider a suite of …
