Friction-In-Design Regulation As 21st Century Time, Place, And Manner Restriction, Brett Frischmann, Susan Benesch

Faculty Publications

Digital networked society needs friction-in-design regulation that targets the digital architectures, supposedly smart (data-driven, algorithmic) systems, and interfaces that shape human interactions, behavior, and will (beliefs, preferences, values, intentions). The relentless push to eliminate friction for the sake of efficiency has hidden social costs that affect basic human capabilities and society. A general course correction is needed.

Friction in the digital networked environment can come in many forms. It can be as simple as a time delay prior to publishing a social media post, a notice that provides salient information coupled with a nudge toward actual deliberation, or a query …

Need-Oriented Evangelism: Encountering, Embracing, And Experiencing God, Petr Cincala, Allison Sauceda

Faculty Publications

This article provides a fresh perspective on evangelism by reflecting a belief in the Triune God--the source of saving truth and loving community. Mission is part of God’s nature; he is the ultimate Missionary. Mission happens naturally whenever children of God intentionally invite and facilitate God’s presence. Over time, the word “evangelism" has become contaminated by myths, a false understanding of God, and unpleasant religious experiences and practices. Genuine evangelism addresses the most burning issues of people’s lives and should be treated as such. True evangelism involves caring about, praying for, and sharing with people. The practical part of this …

Evaluating A Large Language Model’S Ability To Solve Programming Exercises From An Introductory Bioinformatics Course, Stephen R. Piccolo, Paul Denny, Andrew Luxton-Reilly, Samuel H. Payne, Perry G. Ridge

Faculty Publications

Life scientists frequently write computer code when doing research. Computer programming can aid researchers in performing tasks that are not supported by existing tools. Programming can also help researchers to implement analytical logic in a way that documents their steps and thus enables others to repeat those steps. Many educational resources are available to teach computer programming, but this skill remains challenging for many researchers and students to master. Artificial-intelligence tools like OpenAI’s ChatGPT are able to interpret human-language requests to generate code. Accordingly, we evaluated the extent to which this technology might be used to perform programming tasks described …

Learning Experience Design As An Orienting Guide For Practice: Insights From Designing For Expertise, Jason K. Mcdonald, Tyler J. Westerberg

Faculty Publications

In this paper we consider how learning experience design (LXD) improves designers’ capacities to influence learning. We do this by exploring what LXD offers the design of learning environments that help develop learners’ expertise. We discuss how LXD (a) attunes designers to different learning affordances than are emphasized in traditional ID; (b) challenges the universal applicability of common ID techniques; and (c) expands designers’ views of the outcomes for which they can design. These insights suggest that LXD is useful because it refocuses and reframes designers' work around flexible design approaches that are often deemphasized in traditional ID.

What's All The Fuss About Pickleball? Motivational Profiles Of Middle Age And Older Adult Recreational Pickleball Players, David C. Barney, Zack E. Beddoes, Keven A. Prusak, Brandon Weekes

Faculty Publications

As a person becomes older their physical activity options may change or be reduced. One activity that is proving differently among older adults is pickleball. As of 2022 over 3.1 million people in the United States participate in pickleball (USAPA Pickleball, 2022). From the casual observer, many recreational tennis courts have been modified to accommodate the increase of pickleball players. Also, many of these pickleball players are older (40 +). Thus, the purpose of this study was to investigate the motivational profiles of 40 and older adults towards playing pickleball. Generally, it was learned that 40 and older adults participate …

Risks From Spacecraft Breakup Events In Near Rectilinear Halo Orbits, Nathan R. Boone, Robert A. Bettinger, Bryan D. Little

Faculty Publications

Spacecraft breakup events were simulated in the vicinity of the Lunar Gateway’s Near Rectilinear Halo Orbit to evaluate the risk of debris collision with the station. The Monte Carlo simulations model the breakup of an object shortly after deployment from the Gateway, and using the propagated trajectories of over a million particles across 5,000 random breakup events, the likelihood of collision with the Gateway is statistically evaluated. Approaches within 10 km were observed for only 2.4% of the breakup events, suggesting a low risk of collision, but approaches at larger distances that might still generate a debris avoidance maneuver were …

Young Adults’ Cohabitation And Dating Decisions During The Covid-19 Pandemic: A Qualitative Exploration Of Romantic And Developmental Context, Tyler B. Jamison, Jeremy B. Kanter

Faculty Publications

The COVID-19 pandemic caused significant upheaval for couples and families, particularly in terms of living arrangements. Emerging adults had to make quick decisions about where and with whom to shelter in place. In this grounded theory study, we explored how 22 young adults, predominantly living in the United States, navigated relationship decisions during the pandemic. The results suggest that participants were intentional about their choices, particularly in terms of moving in together (or not). The pandemic sometimes changed the timing of cohabitation or the pace of dating relationships; however, these decisions unfolded in tandem with common developmental tasks, such as …

Faculty Publications

Wastewater-based testing (WBT) for SARS-CoV-2 has rapidly expanded over the past three years due to its ability to provide a comprehensive measurement of disease prevalence independent of clinical testing. The development and simultaneous application of WBT measured biomarkers for research activities and for the pursuit of public health goals, both areas with well-established ethical frameworks. Currently, WBT practitioners do not employ a standardized ethical review process, introducing the potential for adverse outcomes for WBT professionals and community members. To address this deficiency, an interdisciplinary workshop developed a framework for a structured ethical review of WBT. The workshop employed a consensus …

Comparison Of A Bottom-Up Gnss Radio Occultation Method To Measure D- And E-Region Electron Densities With Ionosondes And Firi, Dylan J. Shaver, Dong L. Wu, Nimalan Swarnalingam, Anthony L. Franz, Eugene V. Dao, Daniel J. Emmons

Faculty Publications

High-frequency skywave propagation can be heavily impacted by D- and E-region dynamics requiring accurate global measurements to optimize performance. A standard measurement technique is to use ionosondes, but they are unable to measure below 1 MHz and are only available at a limited number of land-locked sites around the globe. In contrast, the Global Navigation Satellite System radio occultation (GNSS-RO) bottom-up method is a new approach specifically designed to generate electron density profiles in the D- and E- region ionosphere. It takes advantage of satellite constellations that currently provide over 20,000 daily measurements and global coverage. In this paper, GNSS-RO …

Lipid Correction For Carbon Stable Isotope Analysis Of Yellowfin Tuna, Michael A. Dance, Mitchell S. Lovell

Faculty Publications

Carbon stable isotopes (δ¹³C) are widely used in ecological studies to understand diet, food web dynamics, and movements of marine fishes. Still, δ¹³C is influenced by lipid content and often requires chemical extraction or mathematical correction. Here, we developed a species-specific mathematical lipid correction for white muscle tissue of yellowfin tuna (Thunnus albacares), a highly migratory finfish of considerable economic and ecological value. Lipid extraction was conducted on yellowfin tuna white muscle tissue (C:N range: 2.96–6.49), and both linear and non-linear lipid correction models for δ¹³C were fitted and assessed. Lipid extraction increased δ …

The World's 100 Worst Invasive Alien Insect Species Differ In Their Characteristics From Related Non-Invasive Species, Zihua Zhao, Cang Hui, Shuo Peng, Shanqing Yi, Zhihong Li, Gadi V.P. Reddy, Mark Van Kleunen

Faculty Publications

While there has been great interest in species characteristics that promote invasiveness, still little is known about the characteristics that distinguish invasive from non-invasive insects. Using a database on the naturalised distributions of alien insects and expert opinions about their impacts, we identified the world's 100 worst invasive insect species. By comparing species characteristics reported in the literature using a meta-analysis, between the 100 worst invasive species and related non-invasive species, we found that invasive insects overall have more pathways of introduction, occur in more habitats, have higher fecundities, higher voltinism, more genes, shorted lifespans and faster development from egg …

Assessing The Threat Of Rosetta 2 On Apple Silicon Devices, Raphaela Mettig, Charles Glass, Andrew Case, Golden G. Richard

Faculty Publications

In November 2020, Apple introduced a new architecture, Apple Silicon, that would power all new laptops and desktops. Based on ARM64 and with many custom features added by Apple, this marked a complete switch from the Intel-based systems that have powered Apple laptops and desktops for many years. With such a radical change, it was obvious that many existing digital forensics and incident response techniques would need to be re-evaluated on the platform. Similarly, several new additions to the operating system are interesting as potential abuse vectors for malware and malicious actors. In this paper, we document our effort to …

Reinvigorating Engineered Noise Controls: A Systems Approach, Jeremy Slagley, Adam Dudarewicz, Pawlaczyk-Łuszczyńska Małgorzata, Francis Slagley

Faculty Publications

Excerpt: Hearing loss is a major worldwide health issue affecting an estimated 1.5 billion people. Causes of hearing loss include genetics, chemicals, medications, lifestyle habits such as smoking, and noise. Noise is probably the largest contributing factor for hearing loss. Noise arises from the workplace, ambient environment, and leisure activities. The easiest noise sources to control are workplace and environmental. Workplace noise is unique in that the employer is responsible for the noise and the worker. Also, workers may be exposed to much higher levels of noise than they would accept elsewhere. Employers follow the traditional hierarchy of controls (substitution/engineering, …

Analog Analogies: Intel V. Hamidi And The Future Of Trespass To Chattels, Maureen E. Brady, James Y. Stern

Faculty Publications

A symposium on great torts cases of the twenty-first century must include Intel Corp. v. Hamidi, the canonical case about whether unwanted e-mail spam sent to a company’s server could give rise to a trespass to chattels claim. While much has been written about Intel, in this Essay, we argue that Intel is as much of a classic for what it reveals about the old-fashioned tort as it is for its more closely examined ruling on “cybertrespass.” The dueling personal property analogies chosen by the majority and dissenting opinions in Intel reveal basic and fundamental disagreements about what …

In the accompanying Comment1, He et al. argue that the determinant role of microbial carbon use efficiency in global soil organic carbon (SOC) storage shown in Tao et al. (2023)2 was overestimated because carbon inputs were neglected in our data analysis while they suggest that our model-based analysis could be biased and model-dependent. Their argument is based on a different choice of independent variables in the data analysis and a sensitivity analysis of two process-based models other than that used in our study. We agree that both carbon inputs and outputs (as mediated by microbial processes) matter when predicting SOC …

Direct Evidence On The Crossover From Bcc To Fcc Stability: A Lattice-Based Aggregation-Volume-Bias Monte Carlo Approach To Polymorphism, Bin Chen

Faculty Publications

A lattice-based version of the aggregation-volume-bias Monte Carlo method that was introduced recently has allowed for the extension of the calculation of the nucleation free energies from liquid clusters to solid clusters. Here, it was used to calculate the nucleation free energies of both bcc and fcc clusters formed by Lennard-Jones particles. Under the simulation conditions considered in this study, a cross-over of the thermodynamic stability from the bcc to the fcc structure was observed directly from the free energy results. In addition, the free energies obtained for both types of clusters were used to extrapolate bulk phase information, including …
