Shedding Light On Inequities Of Power Outages Through Data Transparency, Kelly A. Stevens, Sanam K. Aksha, Mohammad Siddiqur Rahman, Elizabeth Trader, Herbert Longenecker, Rebecca Entress, Thomas Wahl, Christopher Emrich, Kristopher O. Davis

Faculty Publications

In a changing climate, the electricity grid is increasingly exposed to more extreme weather that results in significant power outages. Further, lower income and racial-ethnic minority households are more likely to experience a higher frequency and duration of power outages compared to less socially vulnerable groups. The literature on the unequal impacts of power outages is a new, growing area of research that has been stymied in part due to the difficulty acquiring high spatial resolution, historical power outage data from utilities. In this Perspectives article, we review the availability of power outage data, and what can be learned from …

Perceptions Of Spirituality And Of God: A Psychological Qualitative Study, Christopher E. Peck, Timothy B. Smith, Jamila Mastny Jun 2025

Perceptions Of Spirituality And Of God: A Psychological Qualitative Study, Christopher E. Peck, Timothy B. Smith, Jamila Mastny

Faculty Publications

The majority of people living in the U.S. report that spirituality is an important part of their life that is influential to their well-being. However, individuals vary widely in how they conceptualize spirituality, which often stems from and overlaps with their conceptualizations of God or so-called “God image”. Examination of people’s experiences of spirituality and conceptualization of God can enable psychologists to improve their understanding of individuals’ core personal experiences. This study evaluates both spirituality and God image, as well as the relationship between these two constructs, using qualitative hermeneutic analysis of interviews with 63 adults (51% women, 49% men, …


Prescribed Fire Leads A Pine Flatwoods Specialist Tree Frog To Seek Local Refugia, Ian Biazzo, Pedro F. Quintana-Ascencio Jun 2025

Prescribed Fire Leads A Pine Flatwoods Specialist Tree Frog To Seek Local Refugia, Ian Biazzo, Pedro F. Quintana-Ascencio

Faculty Publications

Pine savannas of the southeastern United States evolved with frequent low-intensity wildfires. Today, land managers use prescribed fires to restore this ecological process while also controlling vegetative fuel accumulation. Given the ubiquitous application of this management tool, studies should consider impacts on target and nontarget taxa in these systems. During fires, animal populations persist in the landscape when individuals emigrate to unburned areas or seek refugia within the burn zone; otherwise, they experience local extirpation. We examined the effect of prescribed fires on a pine flatwoods specialist frog, the pinewoods treefrog Dryophytes femoralis, in a frequently burned pine landscape. …

We present SynthPop, a new open source, modular population synthesis Galactic modeling software to simulate catalogs of Milky Way stars along any sightline outward from the Sun. Motivated by a lack of flexibility in existing Galactic models, SynthPop is coded entirely in python, can be run standalone or as an imported module, and is configured by json files that allow different model components to be switched out as desired. We describe the modular code structure, how the population generation process runs, and how to use the code. We also present model validation testing and known inaccuracies and present an example …


Climatologist Mann's Defamation Suit Victory: Can It Resolve The Crisis Of Expertise, David S. Caudill Jun 2025

Climatologist Mann's Defamation Suit Victory: Can It Resolve The Crisis Of Expertise, David S. Caudill

Faculty Publications

When a jury awarded one million dollars in punitive damages to climatologist Michael Mann, in his defamation suit against writer Mark Steyn (who accused Mann of scientific fraud), it was newsworthy, even surprising, because opinions regarding scientific matters are rarely actionable. And yet it was not seen as a groundbreaking event in terms of legal doctrine, since the outcome was easily justifiable— Steyn’s accusation was provably false. However, even if the Constitutional contours of defamation law did not change, the Mann verdict has far-reaching implications for a major contemporary social phenomenon, namely the so-called crisis of expertise, a term identifying …

Stomach Content And Stable Isotope Analysis Of Invasive Lionfish (Pterois Volitans) In The Florida Keys, Emily E. Shallow, Cassandra N. Glaspie, Michael J. Polito, Mitchell S. Lovell

Faculty Publications

The invasive red lionfish, Pterois volitans, plays a unique role in seagrass and reef ecosystems, where it functions as a top predator and competitor for both food and shelter. Given the ubiquitous distribution of lionfish in the Gulf of Mexico and Caribbean basins, their species provides an excellent opportunity to understand how an invasive predator's diet and primary energy pathways change as a function of size and habitat type. To investigate these patterns, we studied lionfish from a mosaic of deep reef, shallow patch reef, and seagrass bed habitats in the Florida Keys using stomach contents and stable isotope analysis …


How Ai Can Help Mediators Say What They Really Mean, John Lande Jun 2025

How Ai Can Help Mediators Say What They Really Mean, John Lande

Faculty Publications

This article critiques the widespread use of the terms “facilitative” and “evaluative” to describe mediation techniques. Despite their popularity in scholarship and practice, these labels are inconsistently defined, frequently misunderstood, and fundamentally flawed. Drawing on a survey of mediation experts, the article documents significant confusion about how professionals interpret these terms – and how they think that others interpret them. It builds on Leonard Riskin’s critique of the facilitative-evaluative framework, which shows that the language not only oversimplifies complex processes but also risks confusing parties and undermining informed decision-making.

As an alternative, the article proposes a behavioral vocabulary that reflects …

Perceived Adherence-Related Barriers For Youth Living With Hiv In The Southern United States, Kate Weaver, Sarah J. Miller, Sayward Harrison

Faculty Publications

Objective: Youth are at high risk for HIV, accounting for 19% of new diagnoses in the United States (US) in 2021. Highly effective HIV treatment is available in the form of antiretroviral therapy (ART), which enables individuals with HIV to achieve viral suppression. However, youth living with HIV (YLHIV) have poorer ART adherence and lower rates of viral suppression than adults. This study aimed to explore the perspectives of YLHIV and their HIV care providers on barriers and facilitators to ART adherence for YLHIV in the southern US. Methods: Semi-structured qualitative interviews were conducted with YLHIV (n = 16) …

Training Humanoids To Use Good Dispute Resolution Language, John Lande Jun 2025

Training Humanoids To Use Good Dispute Resolution Language, John Lande

Faculty Publications

This short essay uses satire to spotlight the entrenched, misleading terminology widely used in the dispute resolution field, especially in legal and academic settings. Drawing on metaphors of humanoids, bots, and malware, it critiques outdated jargon like “facilitative” and “evaluative” mediation and proposes clearer alternatives derived from Real Practice Systems theory. It describes efforts to train an AI tool, the RPS Negotiation and Mediation Coach, to model improved language use and nudge human users toward better decision-making. Though light in tone, it reflects a serious commitment to reforming the way we talk about and practice negotiation and mediation.

Development And Demonstration Of The Operational Sustainability Index (Opsi): A Multidimensional Metric For Building Performance Evaluation, Oluwafemi Awolesi, Margaret Reams

Faculty Publications

In promoting sustainable cities and societies, accelerating the shift from sustainable building design to sustainable building operations is essential. A persistent challenge lies in the absence of a unified, multidimensional metric that enables meaningful performance comparisons across buildings of similar types and functions, both regionally and globally. This study develops and demonstrates the operational sustainability index (OPSi)—a novel metric grounded in case study research that integrates indoor environmental quality (IEQ) and energy utility quality (EUQ). OPSi is applied to six buildings in three comparative cases: (1) LEED-certified and non-certified dormitories, (2) LEED-certified and non-certified event buildings, and (3) male- and …

This study follows a hermeneutic analytical approach to the literature to clarify and model the distinction between information cocoons and echo chambers. Furthermore, we summarize the selected literature …


Maximum-Likelihood Estimation Of Glandular Fraction For Mammography And Its Effect On Microcalcification Detection, Bryce J. Smith, Joyoni Dey, Lacey Medlock, David Solis, Krystal Kirby Jun 2025

Maximum-Likelihood Estimation Of Glandular Fraction For Mammography And Its Effect On Microcalcification Detection, Bryce J. Smith, Joyoni Dey, Lacey Medlock, David Solis, Krystal Kirby

Faculty Publications

Breast tissue is mainly a mixture of adipose and fibro-glandular tissue. Cancer risk and risk of undetected breast cancer increases with the amount of glandular tissue in the breast. Therefore, radiologists must report the total volume glandular fraction or a BI-RADS classification in screening and diagnostic mammography. In this work, a Maximum Likelihood algorithm accounting for count statistics and scatter is shown to estimate the pixel-wise glandular fraction from mammographic images. The pixel-wise glandular fraction provides information that helps localize dense tissue. The total volume glandular fraction can be calculated from pixel-wise glandular fraction. The algorithm was implemented for images …

Our understanding of the γ-ray sky has improved dramatically in the past decade, however, the unresolved γ-ray background (UGRB) still has a potential wealth of information about the faintest γ-ray sources pervading the Universe. Statistical cross-correlations with tracers of cosmic structure can indirectly identify the populations that most characterize the γ-ray background. In this study, we analyze the angular correlation between the γ-ray background and the matter distribution in the Universe as traced by gravitational lensing, leveraging more than a decade of observations from the Fermi-Large Area Telescope (LAT) and 3 years of data from the Dark Energy Survey (DES). …

We report on IXPE and NuSTAR observations beginning 40 days after the 2024 outburst onset of magnetar 1E 1841−045, marking the first IXPE observation of a magnetar in an enhanced state. Our spectropolarimetric analysis indicates that both a blackbody (BB) plus double power-law (PL) and a double blackbody plus power-law spectral model fit the phase-averaged intensity data well, with a hard PL tail (Γ = 1.19 and 1.35, respectively) dominating above ≈5 keV. For the former model, we find the soft PL (the dominant component at soft energies) exhibits a polarization degree (PD) of ≈30% while the hard PL displays …

Anomalous Collective Modes In Atomic Nuclei Within The Proton-Neutron Interacting Boson Model, Wei Teng, Yu Zhang, Sheng Nan Wang, Feng Pan, Chong Qi, J. P. Draayer

Faculty Publications

Novel collective modes characterized by a B4/2 ratio (≡B(E2;41+→21+)/B(E2;21+→01+)) less than 1.0 that were observed recently have been identified within the proton-neutron interacting boson model (IBM-2) using the consistent-Q Hamiltonian. These modes are shown to give rise to triaxial spectral features, including significant band mixing. The results provide a compelling explanation for the deeply suppressed B4/2 ratio observed in 166W, 168,170Os, and 172Pt, offering new insights into the B(E2) anomaly phenomenon in neutron-deficient nuclei.

We develop a field theory formulation for the interaction of an ensemble of two-level tunneling systems (TLSs) with the electronic states of a superconductor. Predictions for the impact of two-level tunneling systems on superconductivity are presented, including Tc and the spectrum of quasiparticle states for conventional BCS superconductors. We show that nonmagnetic TLS impurities in conventional s-wave superconductors can act as pair-breaking or pair-enhancing defects depending on the level population of the distribution of TLS impurities. We present calculations of the enhancement of superconductivity, both Tc and the order parameter, for TLS defects in thermal equilibrium with the electrons and …

Modeling many-body quantum systems is widely regarded as one of the most promising applications for near-term noisy quantum computers. However, in the near term, system size limitation will remain a severe barrier for applications in materials science or strongly correlated systems. A promising avenue of research is to combine many-body physics with machine learning for the classification of distinct phases. We present a workflow that synergizes quantum computing, many-body theory, and quantum machine learning (QML) for studying strongly correlated systems. In particular, it can capture a putative quantum phase transition of the stereotypical strongly correlated system, the Hubbard model. Following …

The number of family child care (FCC) providers in the United States, or providers who are licensed, certified, or registered to provide care in their home, fell by nearly half between 2005 and 2017 (NCEQA, 2020a). This has implications for families who prefer FCC settings. Understanding providers’ motivations for starting their program may provide policymakers with information on how to better support providers drawn to this setting. Through interviews with 30 Black/bi-racial FCC providers, we found providers started their programs to support family/neighbors, to provide an alternative perceived to be safer than center-based programs, and to be in charge.
