Empowering Citizens Through The Development And Deployment Of A Community-Based Environmental Health Reporting Tool, Willow Sauermilch, Jennifer Irving, Margaret Reams, Chuqi Guo, Stephania Cormier, Jennifer Richmond-Bryant

Division of Basic Science Faculty Publications

Community-based participatory research provides communities with an avenue to actively collaborate with environmental researchers. The research aims to gain insight into critical problems of concern to community members while maintaining community autonomy over the research and its outcomes. This article describes the development and implementation of an environmental health communication tool designed to meet the needs of residents of Colfax, Louisiana, a rural community with limited technological access, which is engaging in advocacy with federal and state regulatory agencies to prohibit open burning and open detonation of military and Superfund wastes at a nearby thermal treatment site. We discuss how …

Threat Perceptions, Defensive Behaviors, And The Perceived Suicide Prevention Value Of Specific Firearm Storage Practices, Michael D. Anestis, Craig J. Bryan, Anna Belle O. Bryan, Daniel W. Capron

Faculty Publications

Introduction: Secure firearm storage has been proposed as a suicide prevention method within the military; however, secure storage practices are uncommon. Service members may perceive limited value in secure storage as a suicide prevention tool and threat-related factors may influence such perceptions. Method: A nationally representative sample of firearm-owning military service members (n = 719) was recruited between December 3, 2021 and January 4, 2022 to complete a self-report survey by Ipsos using their KnowledgePanel calibration approach to optimize representativeness. Results: Threat sensitivity was associated with less perceived suicide prevention value across all within-home storage practices as well as out-of-home …

Cultural Consensus Modeling To Identify Culturally Relevant Reasons For And Against Suicide Among Black Adolescents, Ryan M. Hill, Danielle Busby, Jennifer L. Brown, Eric Sumlin, Estefania Fernandez, Carla Sharp

Faculty Publications

Introduction: The development of evidence-based treatments relies on accurate theoretical frameworks sensitive to the lived realities of the populations from which they are derived. Yet, the perspectives of Black youth are vastly underrepresented in extant theories of suicidal behavior. Cultural Consensus Modeling provides an evidence-based approach for developing a culturally informed understanding of suicide risk among Black youth. Method: Participants were 50 Black adolescents (Mage = 16.20 years; 76.0% male) who completed Phase 1 of a Cultural Consensus Modeling study. Participants freely listed reasons for suicide and reasons for living among similar peer Black youth. Responses were synthesized and coded …

Deceptive Illusory Cues Can Influence Orthogonally Directed Manual Length Estimations, Shijun Yan, Jan M. Hondzinski

Faculty Publications

We examined participants’ abilities to manually estimate one of two perpendicular line segment lengths using curved point-to-point movements. Configurations involved symmetrical, unsymmetrical, and no bisection in upright and rotated orientation alterations to vertical-horizontal (V-H) illusions, where people often perceive longer vertical than horizontal segments for equal segment lengths. Participants used two orthogonally directed movements for length estimations: positively proportional (POS) – where greater fingertip displacement involved longer length estimation between configuration intersection start position and fingertip end, and negatively proportional (NEG) – where greater fingertip displacement from the screen edge start position toward configuration intersection involved a shorter length estimation …

A Data-Driven Approach To Enhance The Prediction Of Bacteria–Metabolite Interactions In The Human Gut Microbiome Using Enzyme Encodings And Metabolite Structural Embeddings, Gopal Srivastava, Michal Brylinski

Faculty Publications

Background: The human gut microbiome is critical for host health by facilitating essential metabolic processes. Our study presents a data-driven analysis across 312 bacterial species and 154 unique metabolites to enhance the understanding of underlying metabolic processes in gut bacteria. The focus of the study was to create a strategy to generate a theoretical (negative) set for binary classification models to predict the consumption and production of metabolites in the human gut microbiome. Results: Our models achieved median balanced accuracies of 0.74 for consumption predictions and 0.95 for production predictions, highlighting the effectiveness of this approach in generating reliable negative …

Rapid Mid-Infrared Spectral Timing With Jwst: Grs 1915+105 During An Mir-Bright And X-Ray-Obscured State, P. Gandhi, E. S. Borowski, J. Byrom, R. I. Hynes, T. J. Maccarone, A. W. Shaw, O. K. Adegoke, D. Altamirano, M. C. Baglio, Y. Bhargava, C. T. Britt, D. A.H. Buckley, D. J.K. Buisson, P. Casella, N. Castro Segura, P. A. Charles, J. M. Corral-Santana, V. S. Dhillon, R. Fender, A. Gúrpide, C. O. Heinke, A. B. Igl, C. Knigge, S. Markoff, G. Mastroserio, M. L. Mccollough, M. Middleton, J. M. Miller, J. C.A. Miller-Jones, S. E. Motta, J. A. Paice, D. D. Pawar, R. M. Plotkin

Faculty Publications

We present mid-infrared (MIR) spectral-timing measurements of the prototypical Galactic microquasar GRS 1915+105. The source was observed with the Mid-Infrared Instrument (MIRI) onboard JWST in June 2023 at an MIR luminosity LMIR ≈ 10³⁶ erg s⁻¹ exceeding past infrared levels by about a factor of 10. In contrast, the X-ray flux is much fainter than the historical average, in the source’s now-persistent ‘obscured’ state. The MIRI low-resolution spectrum shows a plethora of emission lines, the strongest of which are consistent with recombination in the hydrogen Pfund (Pf) series and higher. Low-amplitude (∼1 per cent) but highly significant peak-to-peak …

Interactive Effects Of Co2, Temperature, And Nitrate Limitation On The Growth And Physiology Of Strain Ccmp 1334 Of The Marine Cyanobacterium Synechococcus (Cyanophyceae), Alyssa K. Sharbaugh, Edward A. Laws

Faculty Publications

The marine cyanobacterium Synecococcus sp. (CCMP 1334) was grown in a continuous culture system on a 12:12 h light:dark cycle at all combinations of low and high pCO2 (400 and 1000 ppmv, respectively), nutrient availability (nitrate-limited and nutrient-replete conditions), and temperatures of 21, 24, 28, 32, and 35°C. The maximum nutrient-replete growth rate was ~1.15 day⁻¹ at 32–35°C. Median nutrient-replete growth rates were higher at 1000 ppmv than at 400 ppmv pCO2 at all temperatures. Carbon:nitrogen ratios were independent of pCO2 at a fixed relative growth rate (i.e., growth rate ÷ nutrient-replete growth rate) but decreased with increasing temperature. …

Nodal Finite Element Approximation Of Peridynamics, Prashant K. Jha, Patrick Diehl, Robert Lipton

Faculty Publications

This work considers the nodal finite element approximation of peridynamics, in which the nodal displacements satisfy the peridynamics equation at each mesh node. For the nonlinear bond-based peridynamics model, it is shown that, under the suitable assumptions on an exact solution, the discretized solution associated with the central-in-time and nodal finite element discretization converges to a solution in the L² norm at the rate C1Δt+C2h²/ϵ². Here, Δt, h, and ϵ are time step size, mesh size, and the size of the horizon or nonlocal length scale, respectively. Constants C1 and C2 are independent of h …

Defect Bound States In The Continuum Of Bilayer Electronic Materials Without Symmetry Protection, Daniel Massatt, Stephen P. Shipman, Ilya Vekhter, Justin H. Wilson

Faculty Publications

We analyze a class of bound defect states in the continuum electronic spectrum of bilayer materials, which emerge independent of symmetry protection or additional degrees of freedom. Taking graphene as a prototypical example, our comparative analysis of AA- and AB-stacked bilayer graphene demonstrates that these states originate from the intrinsic algebraic structure of the tight-binding Hamiltonian when trigonal warping is neglected rather than any underlying symmetry. The inclusion of trigonal warping and higher-order hoppings broadens the bound states into long-lived resonances. This discovery provides a distinct pathway to defect and band-structure engineering. We conclude with a proposed protocol for observing …

Orbifolds And Minimal Modular Extensions, Chongying Dong, Siu Hung Ng, Li Ren

Faculty Publications

Let V be a simple vertex operator algebra and G a finite automorphism group of V such that V^G is regular, and the conformal weight of any irreducible g-twisted V-module N for g∈G is nonnegative and is zero if and only if N=V. It is established that if V is holomorphic, then the V^G-module category CV^G is a minimal modular extension of E=Rep(G), and is equivalent to the Drinfeld center Z(VecG^α) as modular tensor categories for some α∈H³(G,S¹) with a canonical embedding of E. Moreover, the collection Mv(E) of equivalence …

Extragalactic Magnetar Giant Flare Grb 231115a: Insights From Fermi /Gbm Observations, Aaron C. Trigg, Rachael Stewart, Alex Van Kooten, Eric Burns, Matthew G. Baring, Dmitry D. Frederiks, Daniela Huppenkothen, Brendan O-Connor, Oliver J. Roberts, Zorawar Wadiasingh, George Younes, Narayana Bhat, Michael S. Briggs, Malte Busmann, Adam Goldstein, Daniel Gruen, Lei Hu, Chryssa Kouveliotou, Michela Negro, Antonella Palmese, Arno Riffeser, Lorenzo Scotton, Dmitry S. Svinkin, Peter Veres, Raphael Zöller

Faculty Publications

Magnetar giant flares (MGFs) are the extremely short, energetic transients originating from highly magnetized neutron stars. When observed in nearby galaxies, these rare events are nearly indistinguishable from cosmological short gamma-ray bursts. We present the analysis of GRB 231115A, a candidate extragalactic MGF observed by Fermi/GBM and localized by INTEGRAL to the starburst galaxy M82. This burst exhibits distinctive temporal and spectral characteristics, including a short duration and a high peak energy, consistent with known MGFs. Time-resolved analysis reveals rapid spectral evolution and a clear correlation between luminosity and spectral hardness, providing robust evidence of relativistic outflows. Archival Chandra data …

Refining A Chain Theorem From Matroids To Internally 4-Connected Graphs, Chanun Lewchalermvongs, Guoli Ding

Faculty Publications

Graph theory and matroid theory are interconnected with matroids providing a way to generalize and analyze the structural and independence properties within graphs. Chain theorems, vital tools in both matroid and graph theory, enable the analysis of matroid structures associated with graphs. In a significant contribution, Chun, Mayhew, and Oxley [2] established a chain theorem for internally 4-connected binary matroids, clarifying the operations involved. Our research builds upon this by specifying the matroid result to internally 4-connected graphs. The primary goal of our research is to refine this chain theorem for matroids into a chain theorem for internally 4-connected graphs, …

Butterfly Species Vary In Sex-Specific Sodium Accumulation From Larval Diets, Luis Y. Santiago-Rosario, Alexander M. Shephard, Emilie Snell-Rood, Achim D. Herrmann, Kyle E. Harms

Faculty Publications

Sodium is essential for animals, and its heterogeneous distribution can cause a range of phenomena, from sodium-seeking behaviours to impacting their performance. Although sodium content in soils and plants is relatively well documented, data for higher trophic levels are limited. Knowledge of the variation in sodium in lower trophic levels could have implications for understanding the behaviour and physiology of species at higher levels. We investigated the variation in tissue sodium concentration between males and females of four butterfly species. Puddling behaviour of Lepidoptera suggests sodium needs of males are generally greater than females, thus, we predicted males would accumulate …

Increased Expression Of The Small Lysosomal Gene Svip In The Drosophila Gut Suppresses Pathophysiological Features Associated With A High-Fat Diet, Brennan M. Mercola, Tatiana V. Villalobos, Jocelyn E. Wood, Ankita Basu, Alyssa E. Johnson

Faculty Publications

Lysosomes are digestive organelles that are crucial for nutrient sensing and metabolism. Lysosome impairment is linked to a broad spectrum of metabolic disorders, underscoring their importance to human health. Thus, lysosomes are an attractive target for metabolic disease therapies. In previous work, we discovered a novel class of tubular lysosomes that are morphologically and functionally distinct from traditionally described vesicular lysosomes. Tubular lysosomes are present in multiple tissues, are broadly conserved from invertebrates to mammals, are more proficient at degrading autophagic cargo than vesicular lysosomes, and delay signs of tissue aging when induced ectopically. Thus, triggering tubular lysosome formation presents …

Solving The Public Defense Crisis In Kansas, Malia N. Brink, Pamela R. Metzger

Deason Center Reports

Kansas has a constitutional obligation to provide counsel to any arrested person who cannot afford to hire a private attorney. But attorney shortages in Kansas threaten this core constitutional right. According to the American Bar Association, there are an average of four attorneys per 1,000 people nationwide. However, only six of Kansas’s 105 counties have two or more attorneys per 1,000 people. In 44 counties, there is just one attorney or fewer per 1,000 residents. The situation is particularly worrisome in rural Kansas. In 2023, nearly half of Kansas’s population lived in rural counties, but 80% of its lawyers lived …

Editor’S Note: Want To Help Develop A Textbook On Comparative Civilizations?, Joseph Drew

Comparative Civilizations Review

Is anyone here in the United States or elsewhere teaching a course in the comparative study of civilizations at the undergraduate level these days?

Since I was thinking about organizing the writing of a textbook on the topic, I began recently by considering what the major areas were to be covered in such a book. What, I wondered, have been the significant approaches scholars have taken over the past century or so to address the fluid, debatable, tenuous meanings and shapes of civilizations?

Ethiopia: Ancient Glory, Awaiting Recovery, Tseggai Isaac

Comparative Civilizations Review

The name Ethiopia is associated in the Book of Genesis with the creation of the world, indicating a sacred and ancient heritage. We find Ethiopia mentioned as having relations with the ancient Biblical nations such as Israel, Egypt, Assyria, and Mesopotamia. Ethiopians get uplifting gratification in reading specific scriptural references from the Bible and applying them to the country. These Biblical allusions include discussion of the Queen of Sheba and her son, King Menelik the First, born from her relationship with King Solomon, who was himself the son of King David, the founder from whom came the lineal parentage of …

Russia’S Geopolitical Civilizational Narratives And Strategic Direction In The Contemporary Multipolar World Order, Sharyl Cross, Igor Okunev

This report describes research undertaken by the Center for Social & Demographic Research on Aging (CSDRA) within the Gerontology Institute at the University of Massachusetts Boston, on behalf of the Up-Island Council on Aging (UICOA). The goals of this project were to investigate the needs, interests, preferences, and opinions of Aquinnah, Chilmark, and West Tisbury residents age 50 or older by engaging the community regarding their experiences and needs relevant to the Council on Aging’s (UICOA’s) objective to identify and serve the needs of older residents of Up-island.

Breach Agents: The Legal Liability Of Third Parties For The Breach Of Reputational Ndas, Mark Fenster

UF Law Faculty Publications

Nondisclosure agreements intended to keep secret information that could harm one or both parties’ reputations have proliferated over the past decade. Many of them have been breached, some quite famously. Does a third party who assists a contracting party in breaching such an agreement — a member of the press or a family member, for example — risk liability for tortious interference with performance of a contract? This article asserts that the answer is no in most instances, in part because of limitations inherent in the tort and in part because such liability would violate the defendant's First Amendment rights. …
