Better Digital Contracts With Prosocial Friction-In-Design, Brett Frischmann, Moshe Y. Vardi Oct 2025

Better Digital Contracts With Prosocial Friction-In-Design, Brett Frischmann, Moshe Y. Vardi

Faculty Publications

Contract law is supposed to enable people to reach genuine agreements and cooperate. If this ideal was ever a reality, the rise of mass market contracts and boil­erplate rendered it pure fiction. Modern consumer contracts are incomprehensible to most people. No one reads them anyway.

Digital contracting involves design features that amplify traditional boilerplate harms and create others. For example, digital contracting is too cheap; low marginal costs lead to overexpansion in scale and scope. To make matters worse, the loss of autonomy from repeat engagement with digital contracting systems is pernicious. People become increasingly predictable and programmable as digital …

Supporting Faculty Parents In Professional Development: Case Studies, Recommendations, And A Call For Inclusive Approaches, Anne Marie Gruber, Lindsay Doukopoulos

Faculty Publications

Educational development is often scheduled during academic breaks with the intent of allowing faculty participation; however, this can actually make it more difficult for faculty who are in parenting roles, particularly during summer and school breaks when childcare options are limited. This article provides case studies from two different institutions describing approaches to offering childcare support to faculty participants in professional development. Ultimately, although both cases were successful, they were limited solutions to what is actually a much larger cultural problem. Our discussion shares lessons learned, recommendations, and urges others to embrace inclusive and equity-focused endeavors in supporting faculty caregivers' …

Land Struggles, Resistance, And Mutual Protection Along The Colorado-New Mexico Border: The Sacred Right Of Self-Preservation, José A. Rivera Ph.D

Faculty Publications

Mutual protection societies proliferated in the American Southwest during a period of rapid social change, 1870-1930, coincident with significant changes in the region’s political economy and increased competition for land and water resources. To resist encroachment and protect their natural resources, hispano communities in Colorado and New Mexico organized mutual benefit and protective associations known as mutualistas, with a large number concentrated in the San Luis Valley of Colorado as well as in many rural counties of northcentral New Mexico. The Costilla Valley of New Mexico is a prototypical hispano settlement initially established as part of the expansive Sangre …

The Sensitivity Of Future Hydroclimate Projections To Topography And Large-Scale Dust Forcing In The Luquillo Mountains Of Eastern Puerto Rico, J. Preece, C. Johnson, T. Mote, P. Miller, M. Williams

Faculty Publications

Precipitation over Puerto Rico is expected to decline in coming decades, threatening an important source of surface water supply. However, earth system models neither resolve fine-scale orographic impacts nor the radiative effects of Saharan dust aerosols on precipitation over the island's mountains. Here, we use the Weather Research and Forecasting model coupled with chemistry (WRF-Chem) to downscale global climate model projections to a convection-resolving 4-km resolution for both dust and no-dust scenarios. We compare the regional hydroclimate during three periods: historical (2014–2018), mid- (2045–2049) and end-21st century (2085–2089), using output from an RCP8.5 simulation of the Community Earth System Model, …

Realization of large effective phonon magnetic moment in monolayer MoS2 has established an important route for exploring intriguing magnetic phenomena in a nonmagnetic material. The sizable coupling between the orbital transition and the circularly polarized phonon results in the large effective phonon magnetic moment. In this work, using magneto-Raman spectroscopy, we investigate substitutional doping of magnetic atoms as a tuning knob of the electronic and phononic properties of MoS2. We show that Fe-doping polarizes the spin of the conduction bands and introduces a localized Fe band underneath the conduction band. As a result, an additional orbital transition between the Mo …


Examining The Effects Of Firearm Lethality And Aggressors’ Intentions To Kill On Injurious Firearm Violence At American Schools: A Research Note, Brent R. Klein, Cory Schnell, Steven M. Chermak, Joshua D. Freilich Sep 2025

Examining The Effects Of Firearm Lethality And Aggressors’ Intentions To Kill On Injurious Firearm Violence At American Schools: A Research Note, Brent R. Klein, Cory Schnell, Steven M. Chermak, Joshua D. Freilich

Faculty Publications

This study examined firearm lethality and aggressors’ lethal intent on injurious fatal and nonfatal school shootings using data from The American School Shooting Study, which covers 329 school shootings in the United States from 1990 to 2016. We developed a new multidimensional construct for measuring shooters’ determination to kill and examined firearm characteristics while considering confounding factors. We identified 11 distinct categories of shooters’ intent, with most showing a strong desire to kill. Both intent and weapon lethality significantly impacted school shooting homicides. Overall, we recommend that prevention and theoretical models should address both factors.

Microarchitectural Malware Detection Via Translation Lookaside Buffer (Tlb) Events, Cristian Agredo, Daniel F. Koranek, Christine M. Schubert Kabban, Jose R. Gutierrez Del Arroyo, Scott R. Graham

Faculty Publications

Prior work has shown that Translation Lookaside Buffer (TLB) data contains valuable behavioral information. Many existing methodologies rely on timing features or focus solely on workload classification. In this study, we propose a novel approach to malware classification using only TLB-related Hardware Performance Counters (HPCs), explicitly excluding any dependence on timing features such as task execution duration or memory access timing. Our methodology evaluates whether TLB data alone, without any timing information, can effectively distinguish between malicious and benign programs. We test this across three classification scenarios: (1) A binary classification problem involving distinguishing malicious from benign tasks, (2) a …

On Good Terms: Pathways To Decolonizing Science-Appropriated Indigenous Terminologies In Arctic Research, Stanislav Saas Ksenofontov, Vera Kuklina, Alexander Kholodov, Andrey Petrov

Faculty Publications

Many western scientific disciplines adopted Indigenous Knowledge and terminology without deference to or understanding of the original meanings and values attached to Indigenous terms and concepts. This form of scientific appropriation has become a serious barrier to efforts of decolonizing Arctic research. The notion of Alaas is an example of such appropriation by the western science-based system of Indigenous knowledge about human–nature relations. This paper aims to discuss the term Alaas as it is conceptualized in both western science and Indigenous knowledge. The paper will explore the development of “alas” as an international permafrost science term and Alaas as an …

Impression Motivations And Mental Health In Collegiate Athletes And Musicians: The Benefits Of Promoting Virtues, Mary L. Inman, Olufemi A. Oluyedun, Erin Moran, Brendyn Mroz, Madison Mccreery

Faculty Publications

This study identifies two key impression-management motivations that arise in public settings: promoting virtues and preventing harm to one’s image. We explored their impact on mental health—specifically, socially-based perfectionism and depressive symptoms. Drawing from regulatory-focus theory, we predicted promotion motivations would predict strong mental health, prevention motivations would predict poor mental health, and promotion motivations would buffer against the negative effects of prevention motivations. Collegiate athletes and musicians (N = 262) completed validated measures of impression motivation, perfectionism, and depressive symptoms. Results revealed that athletes reported lower levels of perfectionism and depressive symptoms than did musicians. Across both groups, …

Wave intensity analysis provides a novel approach to understanding the dynamic interactions between the right ventricle and pulmonary vasculature, particularly in pulmonary hypertension, a condition characterized by elevated pulmonary arterial pressures and vascular remodeling. This prospective study used wave intensity analysis to evaluate right ventricular and pulmonary vascular mechanics in 22 participants with pulmonary hypertension (including precapillary, isolated postcapillary, and combined pre/postcapillary pulmonary hypertension), and three without pulmonary hypertension. Forward and backward compression and decompression waves were quantified at rest and during incremental exercise (25, 50, and 75 W). Relationships between metrics of wave intensity analysis, hemodynamics, right ventricular function, …


Out Of The Vacuum: The Effect Of Tax Liability Changes On Compliance In The Presence Of Withholding Position And Group Affiliation, Chelsea Rae Austin, Donna Bobek Schmitt, Spenser G. Seifert Sep 2025

Out Of The Vacuum: The Effect Of Tax Liability Changes On Compliance In The Presence Of Withholding Position And Group Affiliation, Chelsea Rae Austin, Donna Bobek Schmitt, Spenser G. Seifert

Faculty Publications

Prior research has established that tax liability increases lead to decreased compliance. However, tax liability changes do not happen in a vacuum. Notably, prior research has also identified a withholding phenomenon: individuals in a tax due position are less compliant than those in a refund position. Additionally, tax law changes are often enacted in politically polarized environments. We examine how three factors—tax liability changes, withholding position, and group affiliation—combine to influence individuals' tax compliance decisions. Our experimental results show that a tax increase is universally experienced as a loss, even when coupled with a tax refund and enacted by an …

Event-Based Sensor Noise Modeling For Space-Based Space Domain Awareness, Rachel Oliver, Brian Mcreynolds, Dmitry Savransky

Faculty Publications

Building off the foundation of a physics-based end-to-end model for event-based vision sensors (EVS) observing resident space objects (RSOs), we apply new techniques to model realistic low-light sensor noise. While previous approaches simulate memorized current leakage and apply temporal noise models, our methods improve on these approaches and additionally account for current-following noise as an event source. These improvements are key components for accurate event-generating simulators which can advise requirements and concepts of operations for dedicated event-based Space Domain Awareness (SDA) architectures. The EVS pixel’s independent and asynchronous recording of changes in photocurrent produces data with high temporal resolution and …

Bacterial infections continue to drive the need for more effective and rapid methods for bacterial analysis. To address this, magnetic nanoparticles (MNPs) have emerged as promising tools, especially when their surfaces are modified with bacteria binders. The bis-zinc–dipicolylamine (Zn–DPA) complex is known for its broad affinity to bacteria. We have synthesized MNPs via a thermal decomposition method, encapsulated them in silica, modified their surface with Zn–DPA, and tested their ability to remove bacteria. The MNPs retain their superparamagnetic properties and crystallite structure after being encapsulated. The MNPs coated with silica and Zn–DPA effectively bind and remove both Gram-positive and Gram-negative …
