Assessing The Tax Communications Of E-Commerce Vendors, Part Ii, David Gamage

Faculty Publications

This article presents the second part of a research project on the tax communications of e-commerce vendors. It details the results of a behavioral experiment designed to test how different representations of sales and use tax obligations influence consumer purchasing decisions. The study finds that potentially misleading indicators, such as "No Tax" or "$0 of Tax," significantly increase the likelihood that consumers will purchase from vendors who do not collect sales tax. Compared to vendors who provide accurate information about potential use tax liabilities, consumers were substantially more likely to choose a vendor displaying a "No Tax" message. These findings …

Gendered Expectations: Do Voters Reward Women For Supporting Women's Interests?, Nichole M. Bauer, Anna Gunderson, Jeong Hyun Kim, Elizabeth Lane, Belinda Davis, Kathleen Searles

Faculty Publications

Are women legislators punished for not supporting women's substantive policy interests? We test these gendered expectations. We marshal an original content analysis of cable news coverage and two survey experiments testing voters' assessment of hypothetical legislators on the issues of abortion and equal pay. We find that voters rate both women and men legislators positively for supporting women's issues and negatively evaluate legislators of both genders when they do not support women's interests. We also find that women voters negatively evaluate women legislators who act against women's interests at a greater rate than men voters. While we do not find …

Hydrogen Peroxide Photoformation In Particulate Matter And Its Contribution To S(Iv) Oxidation During Winter In Fairbanks, Alaska, Michael Oluwatoyin Sunday, Laura Marie Dahler Heinlein, Junwei He, Allison Moon, Sukriti Kapur, Ting Fang, Kasey C. Edwards, Fangzhou Guo, Jack E. Dibb, James H. Flynn Iii, Becky Alexander, Manabu Shiraiwa, Cort Anastasio

The high levels of sulfate in wintertime particles in Fairbanks, Alaska, are a subject of keen research interest and regulatory concern. Recent results from the 2022 Alaska Layered Pollution And Chemical Analysis (ALPACA) field campaign indicate that roughly 40 % of wintertime sulfate in Fairbanks is secondary, with hydrogen peroxide (HOOH) the dominant oxidant. Since formation of HOOH in the gas phase should be negligible during ALPACA because of high levels of NOx, we examined whether reactions within particles could be a significant source of HOOH. To test this, we collected particulate matter (PM) samples during the ALPACA campaign, extracted …

Using T-Sne For Characterizing Glitches In Ligo Detectors, Tabata Aira Ferreira, Gabriela González

Faculty Publications

Glitches are non-Gaussian noise transients originating from environmental and instrumental sources that contaminate data from gravitational wave detectors. Some glitches can even mimic gravitational wave signals from compact object mergers, which are the primary targets of terrestrial observatories. In this study, we present a method to analyze noise transients from the Laser Interferometer Gravitational-Wave Observatory observatories using Q-transform information combined with t-distributed stochastic neighbor embedding. We implement classification techniques, examine the influence of parameters on glitch classification, and conduct a week-long daily analysis to track outlier transients over time.

Faculty Publications

Blast injuries and subclinical effects are of significant concern among those Service Members (SMs) participating in military operations and tactical trainings. Studies of SMs repeatedly exposed during training find concussion-like symptomology with transient decrements in neurocognitive performance, and alterations in blood biomarkers. How prior mild TBI (mTBI) history interacts with low-level blast (LLB) exposure, however, remains unexplored, which we investigate in the present study, to identify interindividual biomarker changes from LLB exposures influenced by prior history of mTBI.

Linking Geographic Distribution And Niche Through Estimation Of Niche Density, Tad Dallas, Cleber Ten Caten

Faculty Publications

1. The availability of suitable niche space constrains where species can occur geographically. This tie between niche space and geographic space is crucial when estimating species geographic distributions in a changing climate. However, specific combinations of climatic conditions may be overrepresented in geographic space, highlighting the potential disconnect between climatic niche area and geographic range size.
2. We develop a niche density estimator that accounts for the geographic availability of climatic niche space, relate this to traditional estimates of niche area and explore how these niche estimates are related to species geographic range size.
3. To do this, we use data on over …

Winter Is Coming: What States Should Do Now, Part I, David Gamage, Darien Shanske

Faculty Publications

This Article addresses the unprecedented fiscal challenges facing state governments as federal policy shifts threaten to create a perfect storm of revenue losses and increased service demands. As states confront potential federal cuts to essential services like Medicaid, reduced tax enforcement capacity, and possible tariff-driven economic disruption, we argue that piecemeal responses will prove insufficient.

We propose a seven-step framework for state fiscal resilience: (1) pausing automatic conformity to federal tax changes to preserve revenue bases; (2) enhancing state tax enforcement capacity by hiring federal personnel as the IRS sheds expertise; (3) maintaining and expanding taxpayer service innovations like direct …

The Essence Of An Antitrust Violation, Thomas A. Lambert

Faculty Publications

Judicial embrace of the consumer welfare standard reduced the indeterminacy and political manipulability of U.S. antitrust law. Continual invocations of antitrust’s consumer welfare focus, however, have created the misimpression that consumer harm is a sufficient, not merely a necessary, condition for condemning antitrust-relevant behaviors like agreements in restraint of trade and exclusion-causing unilateral acts. Such a “consumer harm sufficiency” view underlay the plaintiffs’ claims in Epic Games v. Apple and FTC v. Qualcomm and has inspired scholarly proposals to condemn various antitrust-relevant behaviors simply because they occasion consumer harm.

Antitrust economics and dynamic efficiency considerations call for rejection of the …

We present a modified Richardson-Lucy (RL) algorithm tailored for image reconstruction in MeV gamma-ray observations, focusing on its application to the upcoming Compton Spectrometer and Imager (COSI) mission. Our method addresses key challenges in MeV gamma-ray astronomy by incorporating Bayesian priors for sparseness and smoothness while optimizing background components simultaneously. We introduce a novel sparsity term suitable for Poisson-sampled data in addition to a smoothness prior, allowing for flexible reconstruction of both point sources and extended emission. The performance of the algorithm is evaluated using simulated three-month COSI observations of gamma-ray lines of ⁴⁴Ti (1.157 MeV), ²⁶Al (1.809 …

The penstemons are ornamental annual flowering plants native to the Intermountain West and Rocky Mountains and commonly used for urban landscaping. Elite commercial penstemons are generally susceptible to abiotic stresses, including drought, root rot, cold, and high salinity. Firecracker penstemon (Penstemon eatonii), however, is much more tolerant to these stresses than most elite cultivars. Importantly, firecracker penstemon has been reported to hybridize with many other penstemons and therefore provides the opportunity to develop more tolerant elite cultivars through strategic crossing. To facilitate the study and utilization of firecracker penstemon, we sequenced and annotated the genome of a P. …

We investigate the capabilities of the mid-infrared instrument (MIRI) of JWST to advance our knowledge of active galactic nucleus (AGN) dust using the spectral fitting technique on an AGN collection of 21 nearby (z < 0.05) AGN (7 type-1 and 14 type-2) observations obtained with the medium resolution spectroscopy (MRS) mode. This collection includes publicly available AGN and data from the collaboration of Galactic Activity, Torus, and Outflow Survey (GATOS). We developed a tool named MRSPSFisol that decomposes MRS cubes into point-like and extended contributions. We found statistically good fits for 12 targets with current AGN dust models. The model that provides good fits (χ²/dof< 2) for these 12 targets assumes a combination of clumpy and smooth distribution of dust in a flare-disc geometry where the dust grain size is a free parameter. Still, two and one AGN statistically prefer the disc + wind and the classical clumpy torus model, respectively. However, the currently available models fail to reproduce 40 per cent of the targets, likely due to the extreme silicate features not well reproduced by the models and signatures of water-ice and aliphatic hydrocarbon absorption features in most targets. New models exploring, for instance, new chemistry, are needed to explain the complexity of AGN dust continuum emission observed by JWST.
