Wildfire-caused damage to highways has a significant financial cost to the local, regional, and state jurisdictions where they occur. This study examines the financial ramifications of the harm caused to highways by megafires, using a case study of the highways impacted in the U.S. state of Oregon by the five megafires that occurred during the 2020 Labor Day wildfires. This study proposes a method to classify financial road damage from these wildfires based upon curated datasets collected from the Oregon Department of Transportation (ODOT). Hence, this study presents a dataset with labeled classes, which include physical, roadway, and traffic. Physical …
The Obvious Violation Exception To Qualified Immunity: An Empirical Study, Bailey D. Barnes
The Obvious Violation Exception To Qualified Immunity: An Empirical Study, Bailey D. Barnes
Faculty Publications
Qualified immunity shields government officials from civil suits for discretionary actions, as long as the violated right is not clearly established. A right is deemed established when every reasonable official would understand it based on precedent, placing it beyond debate, such that only the plainly incompetent may be held liable. Consequently, even when an act infringes on one's civil rights, a court may deny relief owing to a lack of factually comparable precedent. However, in 2020, the Supreme Court indicated its distrust for overreliance on precedent in certain contexts. In Taylor v. Riojas, the Court held that prison officials violated …
Intimate Partner Violence: Access To Protection Beyond The Pandemic, Rachel J. Wechsler
Intimate Partner Violence: Access To Protection Beyond The Pandemic, Rachel J. Wechsler
Faculty Publications
Civil protection orders are the most common legal remedy victims pursue in response to intimate partner violence (IPV). They are more empowering for victims than the criminal legal system because victims themselves drive the process, instead of prosecutors, and they offer more flexible and tailored relief. This Article argues that victims should be able to choose how they file petitions and participate in civil protection order hearings, and that judges should be required to honor those preferences absent good cause. This conclusion is driven by two new, original sets of empirical data collected from IPV survivors who have sought civil …

Workplace Bullying In Louisiana Academic Libraries: Exploring Worker Status And Demographics, Justin Savage, Andrea Hebert, Catherine Baird
Faculty Publications
Bullying is a phenomenon that exists across cultures, societies, and even species. It can be found everywhere, including the workplace. The present study investigates workplace bullying amongst an approximated census sample of Louisiana academic library workers. Using the Negative Acts Questionnaire—Revised (NAQ-R), the study explores the relationships between experiencing workplace bullying and librarian status, tenure status, years in the profession, age, gender, and race. Although no statistically significant relationships were found between variables, the findings add to a growing body of literature that explores the interrelations of demographic and environmental contexts and bullying experiences.

Production Box Cost Estimating Relationships For Dod Avionics, Carla J. Cisneros, Edward D. White, Brandon M. Lucas, Jonathan D. Ritschel, Robert D. Fass, Shawn M. Valentine
Faculty Publications
The authors use historical information obtained from the Cost Assessment Data Enterprise to estimate recurring production unit cost for DoD avionics via cost estimating relationships (CERs). The specific modeled responses include mean unit cost, median unit cost, and the 100th production unit cost (T100) utilizing learning curve theory. For T100, the authors adopt both a multiplicative and an additive error for CER comparison. Recommended CERs consist of the mean unit cost and the T100 utilizing a multiplicative error. Moreover, results reveal that weight has a significant effect on cost as well as a potential underaccounting of real price change or …
Extraterritoriality's Empire: How Self-Determination Limits Extraterritorial Lawmaking, Evan J. Criddle
Extraterritoriality's Empire: How Self-Determination Limits Extraterritorial Lawmaking, Evan J. Criddle
Faculty Publications
In recent years, a growing number of countries have courted controversy by regulating activities outside their borders. They have used extraterritorial lawmaking to cultivate competitive global markets, strengthen or weaken data privacy, combat foreign terrorism and military aggression, promote human rights abroad, and suppress political dissent at home. This Article explores whether extraterritorial lawmaking can be reconciled with the right to self-determination under international law. I argue that the right to self-determination entitles each national polity to determine the laws and institutions by which it is governed within its territory. Extraterritorial lawmaking violates the right to self-determination when it subjects …

Prescribed Fire Regimes Influence Responses Of Fungal And Bacterial Communities On New Litter Substrates In A Brackish Tidal Marsh, Viet Q. Dao, Crystal N. Johnson, William J. Platt
Faculty Publications
Processes modifying newly deposited litter substrates should affect fine fuels in fire-managed tidal marsh ecosystems. Differences in chemical composition and dynamics of litter should arise from fire histories that generate pyrodiverse plant communities, tropical cyclones that deposit wrack as litter, tidal inundation that introduces and alters sediments and microbes, and interactions among these different processes. The resulting diversity and dynamics of available litter compounds should affect microbial (fungal and bacterial) communities and their roles in litter substrate dynamics and ecosystem responses over time. We experimentally examined effects of differences in litter types produced by different fire regimes and litter loads …

Coupling And Recoupling Coefficients For Wigner’S U(4) Supermultiplet Symmetry, Phong Dang, Jerry P. Draayer, Feng Pan, Tomáš Dytrych, Daniel Langr, David Kekejian, Kevin S. Becker, Noah Thompson
Faculty Publications
A novel procedure for evaluating Wigner coupling coefficients and Racah recoupling coefficients for U(4) in two group–subgroup chains is presented. The canonical U(4)⊃U(3)⊃U(2)⊃U(1) coupling and recoupling coefficients are applicable to any system that possesses U(4) symmetry, while the physical U(4)⊃SUS(2)⊗SUT(2) coupling coefficients are more specific to nuclear structure studies that utilize Wigner’s supermultiplet symmetry concept. The procedure that is proposed sidesteps the use of binomial coefficients and alternating sum series and consequently enables fast and accurate computation of any and all U(4)-underpinned features. The inner multiplicity of a (S, T) pair within a single U(4) irreducible representation is obtained from …

Real-Time Synthesis Of A Nonuniformly Correlated, Partially Coherent Beam Using An Optical Coordinate Tansformation, Milo W. Hyde Iv
Faculty Publications
We design, build, and validate an optical system for generating light beams with complex spatial coherence properties in real time. Beams of this type self-focus and are resistant to turbulence degradation, making them potentially useful in applications such as optical communications. We begin with a general theoretical analysis of our proposed design. Our approach starts by generating a Schell-model (uniformly correlated or shift-invariant) source by spatially filtering incoherent light. We then pass this light through an optical coordinate transformer, which converts the Schell-model source into a nonuniformly correlated field. After the general analysis, we discuss system engineering, including trade-offs among …

Cracks developed in concrete infrastructure are one of the primary mechanisms that degrade their structural integrity, which may result in structural failures. Previous research on soft elastomeric capacitors (SEC) has shown their viability for structural health monitoring of structural materials, including concrete, steel, and fiberglass composites. The SEC, or its derivative version with a corrugated geometry termed corrugated SEC or cSEC, is a parallel plate capacitor. Prior work demonstrated that it was possible to directly paint the electrode interfacing with the structural material onto the structure and adhere the rest of the pre-fabricated sensor onto the wet interface, thereby eliminating …

Biomass burning emits large numbers of organic aerosol particles, a subset of which are called tarballs (TBs). TBs possess a spherical morphology and unique physical, chemical, and optical properties. They are recognized as brown-carbon aerosol particles, influencing the climate through the absorption of solar radiation. Aerosol particles were collected from wildfire and agricultural-fire smoke sampled by NASA's DC-8 aircraft during the Fire Influence on Regional to Global Environments and Air Quality (FIREX-AQ) campaign in the western US from July to September 2019. This study developed an image analysis method using deep learning to distinguish TBs from other round particles that …

Merriam-Webster and Oxford define a xenobiotic as any substance foreign to living systems. Allura Red AC (a.k.a., E129; FD&C Red No. 40), a synthetic food dye extensively used in manufacturing ultra-processed foods and therefore highly prevalent in our food supply, falls under this category. The surge in synthetic food dye consumption during the 70s and 80s was followed by an epidemic of metabolic diseases and the emergence of early-onset colorectal cancer in the 1990s. This temporal association raises significant concerns, particularly given the widespread inclusion of synthetic food dyes in ultra-processed products, notably those marketed toward children.

We examine Ulysses magnetic field observations from 1993 to 1996 as the spacecraft made its first fast-latitude scan from the southern to the northern hemisphere. Most of the observations we use are representative of high-latitude solar minimum conditions. We examine magnetic field power spectra characteristics of interplanetary turbulence at high frequencies, where the spectrum breaks from an inertial range into the ion dissipation range. The onset and spectral index of the dissipation spectrum are consistent with low-latitude observations at 1 au. Both ranges have a ratio of power in perpendicular magnetic field components to parallel components near 3. The power …

The pairing of Unpiloted Aerial Systems (UAS) and Structure from Motion (SfM) has provided new capabilities for modeling freshwater environments. Applications of UAS-SfM range from water quality monitoring to the mapping of aquatic vegetation. The models produced provide users with the ability to analyze features at ultra-high-resolutions and across scales not easily achieved through in situ sampling. Despite the demonstrated benefits of UAS-SfM in freshwater and other natural resource disciplines, there remain fundamental technical challenges in the modeling of environments with homogenous surfaces (e.g., water). In this research, the effectiveness of several image collection and processing approaches for the modelling …

Low-dimensional hybrid organic–inorganic perovskites (HOIPs) are promising electronically active materials for light absorption and emission. The design space of HOIPs is extremely large, as a variety of organic cations can be combined with different inorganic frameworks. This not only allows for tunable electronic and mechanical properties but also necessitates the development of new tools for in silico high throughput analysis of candidate materials. In this work, we present an accurate, efficient, and widely applicable machine learning interatomic potential (MLIP) trained on 86 diverse experimentally reported HOIP materials. This MLIP was tested on 73 experimentally reported perovskite compositions and achieves a …

Precise gamma-ray spectral analysis is crucial in high-stakes applications, such as nuclear security. Research efforts toward implementing machine learning (ML) approaches for accurate analysis are limited by the resemblance of the training data to the testing scenarios. The underlying spectral shape of synthetic data may not perfectly reflect measured configurations, and measurement campaigns may be limited by resource constraints. Consequently, ML algorithms for isotope identification must maintain accurate classification performance under domain shifts between the training and testing data. To this end, four different classifiers (Ridge, Random Forest, Extreme Gradient Boosting, and Multilayer Perceptron) were trained on the same dataset …
