Wastewater surveillance has proven to be a useful tool for evidence-based epidemiology in the fight against the SARS-CoV-2 virus. It is particularly useful at the population level where acquisition of individual test samples may be time or cost-prohibitive. Wastewater surveillance for SARS-CoV-2 has typically been performed at wastewater treatment plants; however, this study was designed to sample on a local level to monitor the spread of the virus among three communities with distinct social vulnerability indices in Shreveport, Louisiana, located in a socially vulnerable region of the United States. Twice-monthly grab samples were collected from September 30, 2020, to March …

The human skin, an important sensory organ, responds sensitively to external stimuli under various harsh conditions. However, the simultaneous achievement of mechanical/thermal sensitivity and extreme environmental tolerance remains an enormous challenge for skin-like hydrogel-based sensors. In this study, a novel skin-inspired hydrogel–elastomer hybrid with a sandwich structure and strong interfacial bonding for mechanical–thermal multimode sensing applications is developed. An inner-layered ionic hydrogel with a semi-interpenetrating network is prepared using sodium carboxymethyl cellulose (CMC) as a nanofiller, lithium chloride (LiCl) as an ionic transport conductor, and polyacrylamide (PAM) as a polymer matrix. The outer-layered polydimethylsiloxane (PDMS) elastomers fully encapsulating the hydrogel …


A Review Of Methods Of Assessing Preference For Social Stimuli, Samuel L. Morris, Madison L. Gallagher, Alva E. Allen Apr 2023

A Review Of Methods Of Assessing Preference For Social Stimuli, Samuel L. Morris, Madison L. Gallagher, Alva E. Allen

Faculty Publications

Research on preference and reinforcer assessments has historically focused on the evaluation of edible and leisure reinforcers, but the identification and use of individualized social reinforcers may be beneficial for several reasons. Recently, many studies have evaluated methods of assessing preference for social stimuli. The procedures and outcomes across these studies have varied greatly, and the current state of evidence for methods of assessing preference for social stimuli remains unclear. Thus, we conducted a review to synthesize all previous research in this area, evaluate the evidence for the utility of this general methodology, and identify factors that may influence its …

Faculty Publications

Catfish (Ictalurus punctatus) skins, as filleting byproduct, were developed into a crispy snack food via air-frying. Consumers rated catfish skin chips (CSC) across sensory modalities (9-point hedonic scales, a just-about-right scale, and “yes/no” for purchase intent, PI) for Plain-, Lemon & Pepper-, and Barbecue-flavored samples during two consumer studies (N = 115 each). Paprika- flavored CSC were excluded from Study 2 due to inferior acceptance and emotional ratings. CSC-elicited emotions were evaluated using a 25-term lexicon with CATA (Check-All-That-Apply) scaling (Study 1) and refined with an abbreviated lexicon containing food-evoked sensation-seeking emotions (5-point intensity scale). The two consumer studies differed …


Evaluation Of Alternative Colony Hybridization Methods For Pathogenic Vibrios, Andrew M. Schwartz, Haley A. Marcotte, Crystal N. Johnson Apr 2023

Evaluation Of Alternative Colony Hybridization Methods For Pathogenic Vibrios, Andrew M. Schwartz, Haley A. Marcotte, Crystal N. Johnson

Faculty Publications

Vibrios, such as Vibrio parahaemolyticus, are naturally occurring halophilic bacteria that are a major cause of foodborne illness. Because of their autochthonous nature, managing vibrio levels in marine and estuarine environments is impossible. Instead, it is crucial to reliably enumerate their abundance to minimize human exposure. One method of achieving this is the direct plating/colony hybridization (DP/CH) method, which has been used to efficiently quantify pathogenic vibrios in oysters and other seafood products. Although successful, the method relies on proprietary resources. We examined alternative approaches, assessed the influence of the reagent suppliers’ source on enumeration accuracy, and made experimental adjustments …

Cancer cell-intrinsic mechanisms affecting radiation immunomodulation could be exploited to optimize systemic effects of localized radiation. Radiation-induced DNA damage is sensed by cyclic GMP-AMP synthase (cGAS), which ultimately activates stimulator of interferon (IFN) genes (STING). Resultant expression of soluble mediators such as CCL5 and CXCL10 can facilitate recruitment of dendritic cells and immune effector cells into the tumor. The primary objectives of this study were to determine the baseline expression levels of cGAS and STING in OSA cells and evaluate the dependence of OSA cells on STING signaling for eliciting radiation-induced expression of CCL5 and CXCL10. cGAS and STING expression, …

The proposed Anthropocene Global Boundary Stratotype Section and Point (GSSP) candidate site of West Flower Garden Bank (27.8762°N, 93.8147°W) is an open ocean location in the Gulf of Mexico with a submerged coral reef and few direct human impacts. Corals contain highly accurate and precise (<±1 year) internal chronologies, similar to tree rings, and their exoskeletons are formed of aragonite and can be preserved in the rock record. Here we present results from a large Siderastrea siderea coral (core 05WFGB3; 1755–2005 CE) sampled with annual and monthly resolutions that show clear markers of global and regional human impacts. Atmospheric nuclear bomb testing by-products (14C, 239+240Pu) have clear increases in this coral starting in 1957 for 14C and the first increase in 1956 for 239+240Pu (potential bases for the Anthropocene GSSP). Coral δ13C declined especially after 1956 consistent with the Suess effect resulting from the burning of fossil fuels. Coral skeletal δ15N starts to increase in 1963 corresponding with the increase in agricultural fertilizers. Coral Hg concentrations (1933–1980) loosely track fluctuations in industrial pollution and coral Ba/Ca increases from 1965–1983 when offshore oil operations expand after 1947. Coral temperature proxies contain the 20th-century global warming trend whereas coral growth declines during this interval.

Health Of Nations: Preventing A Post-Pandemic Emerging Markets Debt Crisis, Lev E. Breydo

Faculty Publications

Sixty percent of low-income countries are currently at “high-risk” of insolvency, necessitating debt relief, according to the International Monetary Fund. The enormity of the problem cannot be overstated; a prospective sovereign debt crisis and economic collapse threatens hundreds of millions of people around the world.

At the same time, the tools to address these challenges are wholly inadequate. Typically, debt reduction is effectuated through statutory systems; sovereign debt is a critical exception, as there is no bankruptcy court for countries. Historically, this void was filled through a complex architecture based on custom, ‘soft law,’ and contractual mechanisms. However, that construct …

Menstrual Justice In Theoretical Context, Vivian E. Hamilton

Faculty Publications

This Essay reviews and places into theoretical contexts Bridget Crawford and Emily Waldman’s invaluable book Menstruation Matters. Although the authors themselves do not explicitly label the theoretical approach that undergirds their work, much of Menstruation Matters: Challenging the Law’s Silence on Periods falls within the liberal feminist legal tradition typical of post-civil rights second-wave feminism. Their work also embodies aspects of critical feminist approaches to law. Crawford & Waldman expose the discriminatory effects of facially neutral laws, the limits of formal equality, and the pitfalls of essentializing or making universal claims about categories of individuals—including women and menstruators.

Legal Order At The Border, Evan J. Criddle Apr 2023

Legal Order At The Border, Evan J. Criddle

Faculty Publications

For generations, the United States has grappled with high levels of illegal immigration across the U.S.-Mexico border. This Article offers a novel theoretical framework to explain why legal order remains elusive at the border. Drawing inspiration from Lon Fuller’s “interactional view of law,” I argue that immigration law cannot attract compliance unless it is general, public, prospective, clear, consistent, and stable; obedience with its rules is feasible; and the law’s enforcement is congruent with the rules as enacted. The flagrant violation of any one of these principles could frustrate the development of a functional legal order. Remarkably, U.S. immigration law …


The Supreme Court Review Act: Fast-Tracking The Interbranch Dialogue And Destabilizing The Filibuster, Aaron-Andrew P. Bruhl Apr 2023

The Supreme Court Review Act: Fast-Tracking The Interbranch Dialogue And Destabilizing The Filibuster, Aaron-Andrew P. Bruhl

Faculty Publications

This Essay presents an analysis of the Supreme Court Review Act, a bill that was recently introduced in Congress. The Act would create a streamlined legislative process for bills responding to new Supreme Court decisions that interpret federal statutes or restrict constitutional rights. By facilitating legislative responses to controversial cases, the Act would promote the “dialogue” that commentators and the courts themselves have used as a model for interbranch relations. The Essay describes how the proposed Supreme Court Review Act would work, discusses some of its benefits, addresses its constitutionality, and raises some questions about its implementation and effects.

Additional longitudinal samples from home environments were obtained from a subset of 11 participants. We observed stability of the microbiomes of both the hand and built environments within the office and home settings; however, …


Trading Nonenforcement, Ryan Snyder Apr 2023

Trading Nonenforcement, Ryan Snyder

Faculty Publications

In recent years, federal agencies have increasingly used nonenforcement as a bargaining chip—promising not to enforce a legal requirement in exchange for a regulated party’s promise to do something else that the law doesn’t require. This Article takes an in-depth look at how these nonenforcement trades work, why agencies and regulated parties make them, and the effects they have on social policy. The Article argues that these trades pose serious risks: Agencies often use trading to evade procedural and substantive limits on their power. The trades themselves present fairness problems, both because they tend to reward large, well-connected firms and …
