Highly sensitive vertically aligned carbon nanotube arrays (VANTAs) interdigitated electrode (IDE) arrays are developed for electrochemical biosensing of two cytokines (i.e., interleukin-10 (IL-10) and interferon-gamma (IFN-𝜸)) that are useful for early detection Johne’s disease (Bovine Paratuberculosis) in cattle. The high aspect ratio VANTA-IDEs (50–60 μm in height) are grown through a chemical vapor deposition process from an iron (Fe) catalyst that is lithographically patterned on a silicon wafer with equal finger width and inter-finger spacing of 25 μm. After functionalization with distinct antibodies the VANTA-IDEs are capable of selective detection of both IL-10 and IFN-𝜸 within an actual biological matrix …
Debt, Race, And Physical Mobility, Kate Sablosky Elengold
Debt, Race, And Physical Mobility, Kate Sablosky Elengold
Faculty Publications
Residents in every state in the United States can lose their driver’s license or car registration because they owe debt to the state. At least eleven million people across the United States suffer these debt-based driving restrictions at any given time. Because Americans overwhelmingly rely on personal automobiles for transportation, states, by controlling access to driver’s licenses and vehicle registrations, use debt policy to control where and how people travel. And because these laws disproportionately affect people of color, primarily Black people, this kind of regulation props up racial segregation in both location and opportunity. This Article’s first contribution is …
Why Study State Constitutional Law?, Marcus A. Gadson
Why Study State Constitutional Law?, Marcus A. Gadson
Faculty Publications
In light of the Supreme Court retrenching on certain rights in recent years, more Americans are paying attention to state constitutions. This moment therefore offers an opportunity to explain why scholars, lawyers, and ordinary citizens should take state constitutions as seriously as they do the U.S. Constitution, and consider studying them an intellectually rewarding and important endeavor. In this essay, I attempt to do that. Earlier in our history, state constitutions helped define what it meant to be American. Through the process of drafting and interpreting constitutions, prior generations decided what popular sovereignty meant, who qualified as part of “the …
Labor Law’S Impact On The Post-Dobbs Workplace, Jeffrey M. Hirsch
Labor Law’S Impact On The Post-Dobbs Workplace, Jeffrey M. Hirsch
Faculty Publications
The Supreme Court’s Dobbs decision has left many workers, especially in states with restrictive abortion-related laws, in a precarious position. Labor laws and unions, however, provide one avenue for providing these workers with more protections. Unions can demand bargaining to protect or expand health care, leave, and other terms of employment that give workers with means to obtain abortion-related care. Unions can also provide members legal defense and other support if they face prosecutions. Additionally, both union and non-union workers who make up the vast majority of workers in states with restrictive laws may have labor law protection for discussing …

El Pequeño Riego De México: Puebla, Morelos, Y Baja California Sur, José A. Rivera Ph.D.
Faculty Publications
Small to medium-sized irrigation systems in México are characterized in the literature as El Pequeño Riego. Some systems can be compared to those in northern New Mexico and southern Colorado, while others are significantly larger and more complex. Regardless of irrigated acres or hectáreas, however, there are many elements that are commonly shared across these regions. Firstly, the irrigation works are based on the use of acequias dug from the earth that need to be maintained and cleaned season to season. The terms canals and acequias are interchangeable. Secondly, the irrigators themselves, whether called parciantes or regantes, take …

Review Of The Cavity Effect: Modeling And Impact Of Cavity Shape On Apparent Radiative Surface Properties, Ehsan Mofidipour, Matthew R. Jones, Brian D. Iverson
Faculty Publications
Radiative surface properties play a critical role in the analysis, design, and optimization of thermal systems. Geometry has a strong influence on the emission and absorption characteristics of a surface. Modification of radiative surface properties may be achieved by using engineered surfaces or cavities by capitalizing on the cavity effect. A model for the apparent emissivity of an arbitrarily shaped cavity with spectrally and directionally dependent radiative surface properties is presented in this work. This model is verified through comparison with published models of the apparent radiative properties of cylindrical cavities. The merit of this model is demonstrated by obtaining …

Drop Retention And Departure In Adiabatic Shear Flow On Structured Superhydrophobic Surfaces, Blake M. Lyons, Daniel Maynes, Julie Crockett, Brian D. Iverson
Drop Retention And Departure In Adiabatic Shear Flow On Structured Superhydrophobic Surfaces, Blake M. Lyons, Daniel Maynes, Julie Crockett, Brian D. Iverson
Faculty Publications
Drops are retained or held on surfaces due to a retention force exerted on the drop by the surface. This retention force is a function of the surface tension of the liquid, drop geometry, and the contact angle between the drop and the surface. When external or body forces exceed the retention force, the drop begins to move. This work explores the conditions for which drop departure occurs on structured superhydrophobic surfaces in the presence of an applied shear flow. Drop departure is explored for five microstructured superhydrophobic surfaces, one nanostructured carbon nanotube surface and one smooth hydrophobic surface. Surface …

In a digital age where screens are as ubiquitous as crayons once were, the relationship between screen use and a child’s development necessitates examination. This study investigates the effect of screen use—both by children and their parents—on children’s ability to delay gratification, a key predictor of future success. Utilizing an experimental design modeled after the Stanford Marshmallow Experiment, we found that children’s screen use did not significantly affect their ability to delay gratification. However, parental screen use for entertainment purposes was negatively associated with children’s capacity to delay gratification. Additionally, screens proved to be a more potent temptation than traditional …

Short And Synthetically Distort: Investor Reactions To Deepfake Financial News, Scott Emett, Marc Eulerich, Jeffrey Pickerd, David A. Wood
Faculty Publications
Recent advances in artificial intelligence have led to new forms of misinformation, including highly realistic “deepfake” synthetic media. We conduct three experiments to investigate how and why retail investors react to deepfake financial news. Results from the first two experiments provide evidence that investors use a “realism heuristic,” responding more intensely to audio and video deepfakes as their perceptual realism increases. In the third experiment, we introduce an intervention to prompt analytical thinking, varying whether participants make analytical judgments about credibility or intuitive investment judgments. When making intuitive investment judgments, investors are strongly influenced by both more and less realistic …

The audit committee is a widely recognized mechanism of effective corporate governance. We advance prior literature reviews by using bibliometric analysis techniques that comprehensively process large bodies of bibliometric information. We base inferences on citation patterns of 1,173 articles to identify concepts that “shine through” within the scientific understanding of audit committees. Using content analysis, we then analyze these concepts and explore existing interrelationships. We document a declining influence of audit committee research, as well as a widening gap between the quantitative and qualitative research camps. While the former is mostly derivative in nature, the latter produces innovative insights on …

Estimating The Likelihood Of Future Tax Settlements, Jared Jennings, Joshua A. Lee, Erin Towery
Faculty Publications
Corporate income tax settlements represent a substantial cash outflow for many U.S. firms. This study develops an ex-ante measure of future corporate income tax settlement likelihood using quantitative and qualitative information from Form 10-K. We find that both quantitative and qualitative information are incrementally useful in predicting future tax settlements. We then use our new measure to examine the association between predicted future tax settlements and cash holdings. In contrast with prior research documenting a positive association between reserves for uncertain tax positions and cash holdings, we find that firms with a higher likelihood of future tax settlements hold less …

Strategic Alignment, Performance, And The Moderating Effect Of Regulatory Fit, Hayden T. Gunnell, Steven D. Smith, Travis W. Steadman
Faculty Publications
We examine how the alignment of performance measurement and strategy affects performance on a multidimensional task. Our experiment varies both the strategy (speed versus accuracy) of the hypothetical firm for which participants work and the individual performance measure that is reported to them, creating two conditions of clear alignment and two of clear misalignment. We find that while workers are responsive to the performance measure regardless of its alignment, they are also sensitive to the strategy such that costly alignment effects are observed. We also predict and find that workers respond asymmetrically to misalignment in accuracy performance but not in …

Origami has inspired work in many fields of science and engineering. However, it can be difficult to transfer the motion of an origami design from folded paper to thicker, stiffer materials. When using engineering materials, creases from an origami fold pattern are usually replaced with “surrogate folds”. While many different surrogate folds have been developed, it is challenging for a designer to quickly survey and compare potential surrogate folds. Surrogate folds can improve many origami-inspired designs and applications by changing how the designs are manufactured and how they behave. This work categorizes compliant mechanisms that may be effective as surrogate …
