Introduction: Access to medications for opioid use disorder (MOUD) varies across racial and ethnic groups. As the largest payer for MOUD, Medicaid has potential to ensure access for all enrollees. We aimed to quantify recent trends and state variation in MOUD use by race and ethnicity in Medicaid. Methods: Using a distributed research network, we conducted a cross-sectional study of 11 states' Medicaid data from 2016 to 2020. Among enrollees diagnosed with opioid use disorder (OUD), we measured the percent receiving MOUD (overall; and methadone, buprenorphine, naltrexone, separately), continuity of MOUD for ≥180 days, and claims-based overdose event rates. We …

Field Calibration Of Flow Over Tilting Weirs In Canals, Joseph E. Pugh, Timothy K. Gates, S. Karan Venayagamoorthy, Caner Kutlu

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Tilting weirs are widely used to regulate water levels in open channel irrigation systems and can also provide flow measurement capability that helps optimize irrigation efficiency and ensure equitable water distribution. This case study demonstrates adaptation of lab-based tilting weir ratings to field settings, where flow behavior is more complex. We compile and analyze an extensive data set derived from independent studies of five structures within three canal systems, featuring both lined and unlined channels with discharge ranging from 0.35 to 15 m3/s (12 to 530 ft3/s). Results indicate that lab-based rating equations can be calibrated to account for site-specific …

Five-State Seismic Damage Classification Of Steel-Girder Bridges On Soft Soil Using Directional Intensity Measures And Multi-Parameter Damage Indices, Ibrahim Alomari, Woubishet Zewdu Taffese, Mohammad Hossein Afsharmovahed, Genda Chen

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Rapid yet accurate post-earthquake damage assessment of highway bridges is essential to ensure transportation network resilience. Traditional inspection, fragility analysis, and finite element modeling are time-consuming or inaccurate for real-time decision-making. This study compares ten machine-learning classifiers for the seismic damage states of highway steel-girder bridges that incorporate directional intensity measures to represent the variance of ground motions. Based on the nonlinear time-history analyses of two Missouri bridges, one Michigan bridge, and one Wisconsin bridge, multi-parameter structural damage indices were proposed and mapped to five damage states from none to collapse. Among ten supervised algorithms studied, the artificial neural network …

Non-Uniform Mixing Of Quantum Walks On The Symmetric Group, Avah Banerjee

Computer Science Faculty Research & Creative Works

It is well-known that classical random walks on regular graphs converge to the uniform distribution. Quantum walks, in their various forms, are quantization's of their corresponding classical random walk processes. Gerhardt and Watrous (2003) demonstrated that continuous-time quantum walks do not converge to the uniform distribution on certain Cayley graphs of the Symmetric group, which by definition are all regular. In this paper, we demonstrate that discrete-time quantum walks, in the sense of quantized Markov chains as introduced by Szegedy (2004), also do not converge to the uniform distribution. We analyze the spectra of the Szegedy walk operators using the …

The Long Arc Of Global Citizenship: Historical Foundations, Modern Challenges, And Institutional Innovation At Rollins College, Wenxian Zhang

Faculty Publications

The concept of global citizenship can be traced back to the Greek and Roman periods in Western civilization, as well as to ancient Eastern philosophies. Representing both a prescriptive ideal and an aspirational faith in humanity, the notion is closely linked to the historical development of cosmopolitanism, transnationalism, and transnationality. This study first reviews the rich historical roots and core values of global citizenship, along with the growing need for global citizenship education in the modern era. It then highlights several influential individuals who strongly championed its principles, including theoretical physicist and Nobel Prize winner Albert Einstein and internationalist and …

Autistic Traits And Mental Health Support Service Use Among Parents Of Young Children With Autism, Margaret Janse Van Rensburg, Robert Hock, Emmanuella Asabea Twum, Resia-Maria Cooper, Abigail K. Reza Jameson, C. Andrew Conway, Mark Ethan Feinberg

Faculty and Staff Publications

Parents of children recently diagnosed with autism often experience elevated psychological distress, yet little is known about whether parental autistic traits are associated with support-seeking. Using baseline data from a randomized controlled trial of a parent mentoring intervention, this study examined support use among 355 parents of children aged 18 months to 8 years whose child had received an autism diagnosis within the previous 12 months. Parental autistic traits were assessed using the Ritvo Autism and Asperger Diagnostic Scale–14 (RAADS-14). Overall, 36.1% of parents reported accessing support for stress, emotional, or mental health concerns, and 33.2% scored above the RAADS-14 …

Antiviral Activity Of The Polyene Macrolide Roseofungin Against Influenza A Virus: In Vitro, In Ovo, And Preliminary In Vivo Evaluation, Ahdrey P. Bogoyavlenskiy, Vladimir Berezin, Pavel Alexyuk, Madina Alexyuk, Irina Zaitseva, Aidar Mukhametkaliyev, Yergali Moldakhanov, Elmira I. Anarkulova, Timur Kerimov, Vyacheslav Dushenkov

Publications and Research

Roseofungin, a polyene macrolide antibiotic produced by Streptomyces roseoflavus, was evaluated for antiviral activity against Influenza A virus using complementary in vitro, in ovo, and preliminary in vivo toxicity models, supported by molecular docking and molecular dynamics simulations. The compound exhibited antiviral activity against multiple influenza A virus subtypes, including an oseltamivir-resistant H1N1 strain, with EC₅₀ values ranging from 2.0 to 2.5 μg/mL and selectivity indices of 20–25. Functional assays demonstrated that roseofungin interfered with early stages of the viral life cycle by reducing viral adsorption and partially inhibiting neuraminidase activity. In virucidal assays, treatment with roseofungin resulted …

Designing By Chance: Controlled Randomness As A Generative And Constructible Strategy For Architectural Façade Composition—A Case Study, Maruan Halabi

All Works

Façade design has long oscillated between repetitive order and visual disorder, and computational tools now make controlled irregularity easy to generate but hard to build; comparatively few studies follow a stochastic envelope from algorithm to a completed building. This paper examines controlled randomness as a deliberate, constructible strategy for façade composition. A parametric Grasshopper workflow erodes a square grid of wall modules through a seeded random-reduction rule—a deterministic, rule-based procedure that uses no machine learning or artificial intelligence—whose intensity increases up the building, producing a depth-modulated, quarry-like relief realized with one ordinary product—40 × 20 cm concrete blocks in four …

Human-Centered Electric Vehicle Adoption Framework For Smart Mobility: Modeling Perceived Range And Charging Anxiety As A Psychological Barrier, Fatemeh Nazari, Abolfazl (Kouros) Mohammadian, Thomas Stephens

Civil Engineering Faculty Publications

Electric vehicles (EVs) offer a transformative pathway toward reducing the environmental, economic, and health-related externalities of internal combustion engine vehicles in urban settings. Despite substantial advances in battery technology, charging infrastructure expansion, and supportive policy incentives, EV penetration remains limited which poses challenges for smart and sustainable mobility planning. A critical yet insufficiently modeled barrier to adoption lies in the psychological perceptions surrounding electric driving range and charging reliability, which is commonly framed as “range anxiety,” but more broadly reflecting perceived range and charging anxiety. To address this gap, this study introduces a latent psychological construct capturing individuals’ perceived range …

Impacts Of Structural Design On Oyster Survival And Predation In Restored Oyster Reefs, Jaden E. Akers, Nigel Temple, J. Marcus Drymon, Just Cebrian, J. Patrick Broussard, Ashleigh Robbins, Eric Sparks

Research Data

Restoration efforts are critical to ensure healthy oyster populations and the ecosystem services they provide. However, restoration is expensive and outcomes are mixed due, in part, to oyster predation on contemporary structures. Here we assess the effects of reef structural design elements on predator behavior and oyster survival using a paired field and laboratory mesocosm experimental approach. Experimental reefs (n=128) were constructed out of formed concrete and varied in structural features including vertical relief (short vs. tall), continuity (e.g., gapped or continuous), position in the water column (on-bottom or elevated), and slope. Each of the 8 designs was replicated eight …

Hkc07 - Bayesian Conspiracy Theorists? Equivocal Signals And Persistent Polarization, Javier A. Granados Samayoa, Timothy Hyde

Oberlin College Kasper Economics and Business Working Paper Series

Conspiracy beliefs are the subject of a rich literature in psychology, which explains them through personal dysfunction. The corresponding economics literature is scant. We offer a demand-side model of belief in specific conspiracy theories with no biases, misspecification, or strategic manipulation. A conspiracy, by its nature, generates equivocal evidence about its own existence, because the same strength that produces more to detect also produces better concealment. We model belief in a specific conspiracy theory as learning about the strength 𝑞 of a cabal, a stand-in for the secretly coordinating actors of any conspiracy theory. In the baseline the cabal influences …

Hkc08 - Neglect At Your Own Risk? Evidence On Risk-Taking Prevalence And Motives From The Field, Saurabh Bhargava, Timothy Hyde

Oberlin College Kasper Economics and Business Working Paper Series

We study risky choice in a field setting where employees choose among goal-reward contracts resembling financial lotteries and where we observe both choices and beliefs. We find risk aversion and choice heterogeneity far exceeding expected utility predictions and unexplained by prominent behavioral motives like overconfidence, nonlinear decision weights, and loss aversion. We propose and experimentally validate a heuristic explanation for risk taking involving contingency neglect during pairwise evaluation. The heuristic fits the field and lab data better than leading alternative models, uniquely predicts the belief distortions and framing effects we document, and offers a potential explanation for empirical insurance puzzles.

Hkc10 - Disasters, Labor Migration, And Migrant Downgrading: Evidence From Typhoons In The Philippines, Emir Murathanoglu

Oberlin College Kasper Economics and Business Working Paper Series

I study how typhoons affect international labor migration from Philippine municipalities using administrative data on the universe of new migrant contracts. Typhoons increase out-migration for up to three years, but simultaneously shift migrants toward lower-paying occupations and destinations. Average migrant cohort wages fall by 0.27– 0.41% for each 1% typhoon-induced increase in migration. This fall is not explained by observable selection, as typhoon-induced migrants have higher educational attainment. These patterns are consistent with a simple migration search model, where worsening origin conditions incentivize potential migrants to search and leave for lower-paying overseas contracts. Despite this downgrading, back-of-the-envelope calculations suggest 16–19% …

Effects Of Concurrent Neuropathologies With Alzheimer Disease Neuropathologic Change On Cognitive Decline: Minimal Impact Of Vascular Brain Injury Compared With Other Combinations, Sarah M Yasuda, Charles Mock, Kathryn Gauthreaux, Kwun C G Chan, C Dirk Keene, Jessica E Culhane, Yen-Chi Chen, Walter Kukull

2020-Current year OA Pubs

We examined cognitive changes associated with several neuropathologic entities, alone and in combination. We studied 808 participants from the National Alzheimer's Coordinating Center to assess associations between neuropathologic diagnoses (from autopsy) and neuropsychologic test scores (trajectories over time for 5 domains: overall cognition, episodic memory, attention, language, executive function). Neuropathologies included: Alzheimer disease neuropathologic change (ADNC), Lewy body disease (LBD), vascular brain injury (VBI), and limbic-predominant age-related TDP43 encephalopathy neuropathologic change (LATE-NC). Using linear mixed-effects models, we examined trajectories of cognitive decline for ADNC alone compared to ADNC plus LBD, VBI, or LATE-NC. We also examined differences between observed trajectories …

Financial Toxicity And Cost-Related Imaging Nonadherence In Pediatric Outpatient Imaging, Shireen E Hayatghaibi, Gregory L Jordan, Tucker Hansen, Amy E Ensing, Aditi Gupta, Evan A Mihalakakos, Bin Zhang, Pradipta Debnath, Carrie C Coughlin

2020-Current year OA Pubs

RATIONALE AND OBJECTIVES: Financial toxicity, defined as the financial burden and stress experienced due to medical costs, is increasingly recognized as a key patient-reported outcome and has been linked to cost-related non-adherence in adult populations. However, its prevalence and impact in pediatric imaging are unknown. We examined the prevalence and predictors of financial toxicity among families of children undergoing outpatient imaging and its association with imaging non-adherence.

MATERIALS AND METHODS: We conducted a prospective cross-sectional survey of parental caregivers of children (< 18 years of age) undergoing outpatient imaging at two free standing children's hospitals in the U.S. (July 2024-May 2025). Financial toxicity was measured using the adapted FACIT-COST instrument and scores < 26 indicated high financial toxicity. Multivariable logistic regression examined associations between family characteristics and high financial toxicity.

RESULTS: Among 399 caregivers, the mean FACIT-COST score was 24.6 (SD 10.2), and 49% were categorized as having …

Spatiotemporal Assessment Of Coastal Urban Heat In Buenos Aires Using Satellite Landsat Lst, Noah Morales, Lleyton Naar, Dan Macchiarella, Kevin Adkins, Ronny Schroeder

Student Works

Coastal urban environments exhibit complex surface temperature patterns driven by interactions among water, vegetation, and built infrastructure. This study investigates land surface temperature (LST) variability along a coastal-to-urban transect in Parque de los Niños, Buenos Aires, by integrating multi-year satellite Landsat LST with high-resolution thermal data collected from an uncrewed aircraft system (UAS). Landsat provides the temporal depth necessary to assess seasonal and interannual variability in surface temperature, including responses to extreme summer conditions. However, their spatial resolution limits the ability to resolve fine-scale thermal gradients near shoreline boundaries and within heterogeneous urban landscapes. UAS thermal observations address this limitation …

Racialised Gradients Of Human Value And Marx’S Working Day, Today, Anthony F. Peressini

Philosophy Faculty Research and Publications

This paper reconsiders the ‘working day’ discussion in chapter ten of Capital and how it centres two parameters in the generation and appropriation of surplus value. The first parameter is the cost of labour-power paid by the capitalist and the second is the time that the worker must yield to the capitalist: the ‘length of the working day’. The first parameter represents the amount of pay required to keep the worker alive and able to work. Marx understood it as a lower limit below which capitalism would cease to function. This paper argues that, while analytically coherent, this understanding of …

Cartel Violence Fueled By Ghost Guns: A React Case Study, Collin Stigge, Isaac J. Moelter

Reports, Projects, and Research

On December 9th, 2021, Andrew Scott Pierson pleaded guilty to charges related to his key role within an arms trafficking ring which smuggled ghost guns to Cartel de Noreste (CDN) and the Jalisco New Generation Cartel (CJNG).1 Ghost guns are un-serialized firearms that are put together by components purchased either as a kit or as separate pieces. The operation involved Pierson and his close relatives and friends in a multi-state operation. Pierson and his network purchased the gun parts domestically in the United States across multiple states, made modifications, smuggled them across the US-Mexico border to finish construction, then sold …

Tidally Driven Topographic Eddies Exploited By Manta Feeding Aggregations, Harvey Cairns, Daniel Conley, Christopher Stokes, Tim Scott, Philip Hosegood

School of Biological and Marine Sciences

The seasonal feeding aggregations of reef manta rays (Mobula alfredi) in Hanifaru Bay, Maldives, are the largest known of their kind, yet the mechanisms facilitating this phenomenon remain poorly understood. Understanding these drivers is crucial for effective conservation and management, as protecting key foraging habitats requires knowledge of the physical processes influencing prey availability. While previous studies highlight the role of zooplankton in attracting manta, the oceanographic mechanisms responsible for concentrating prey within the bay remain hypothesised but unproven. Specifically, the influence of eddy dynamics, tidal forcing, and regional circulation on zooplankton distribution has not been thoroughly examined.A …
