Design, Alpha Testing, And Beta Testing Of A 3-D Printed Open-Hardware Portable Cryopreservation Device For Aquatic Species, William M. Childress, Yue Liu, Terrence R. Tiersch

Faculty Publications

Efforts in development of germplasm repositories to preserve genetic resources of aquatic species are impeded globally by a lack of standardized, inexpensive, reproducible, and portable cryopreservation technologies. The present work demonstrates a 3-D printed standardizable freezing device that can be used with nitrogen vapor shipping dewars for on-site sperm cryopreservation for aquatic species and be distributed as open-hardware. This device could hold 22 French straws (0.25-mL or 0.5-mL) and a quick-release ring design could eject straws directly into a canister inside a dewar by pressing a button after freezing. The final prototypes produced cooling rates of 1 to 68°C/min for …

Wooing “Willing Dupes”: The Bush Administration’S Use Of Emotional Language In The Drive Toward War With Iraq, Michael F. Russo

Faculty Publications

The publicly available texts of the George W. Bush administration from September 11, 2001, to March 19, 2003, as presented in The Public Papers of the Presidents of the United States, were analyzed for word frequency and the words themselves analyzed for emotional weight using the NRC Emotion Intensity Lexicon. Transcripts of six television news agencies (ABC, CBS, NBC, CNN, FOX, and PBS) were also analyzed for word frequency to determine the extent to which these agencies may have repeated and consequently amplified the rhetoric of the administration. Public opinion polling for this same period was examined in an …

Consumption of contaminated produce remains a leading cause of foodborne illness. Increasingly, growers are altering agricultural practices and farm environments to manage food-safety hazards, but these changes often result in substantial economic, social, and environmental costs. Here, we present a comprehensive evidence synthesis evaluating the efficacy of soil, non-crop vegetation, animal, landscape, and irrigation water management strategies aimed at reducing produce-safety risk in North America. We systematically summarized findings from 78 peer-reviewed papers on the effect of 21 management practices on the prevalence, abundance, or survival of four foodborne pathogens (i.e., E. coli, Salmonella spp., Listeria spp., and Campylobacter spp.), …

Elements of this initiative began one-by-one over the last decade and were aggregated into a comprehensive implementation plan—the 2020 CC&E Diversity, Equity, and Inclusion Action Plan. Based on best practices in the “physical sciences” (i.e., geosciences, including oceanography), the plan aims to augment recruitment and retention using limited resources and personnel. The long-range goal is to increase the number of PhD graduates from underrepresented groups by employing strategies that start at the 6–12th grade level. The …

Effects Of Anisotropy And Disorder On The Superconducting Properties Of Niobium, Mehdi Zarea, Hikaru Ueki, J. A. Sauls

Faculty Publications

We report results for the superconducting transition temperature and anisotropic energy gap for pure niobium based on Eliashberg’s equations and electron and phonon band structures computed from density functional theory. The electronic band structure is used to construct the Fermi surface and calculate the Fermi velocity at each point on the Fermi surface. The phonon bands are in excellent agreement with inelastic neutron scattering data. The corresponding phonon density of states and electron–phonon coupling define the electron–phonon spectral function, α²F(p, p′; ω), and the corresponding electron–phonon pairing interaction, which is the basis for computing the superconducting properties. The …

Perspective On Predictive Modeling: Current Status, New High-Order Methodology And Outlook For Energy Systems, Dan Gabriel Cacuci

Faculty Publications

This work presents a perspective on deterministic predictive modeling methodologies, which aim at extracting best-estimate values for model responses and parameters along with reduced predicted uncertainties for these best-estimate values. The two oldest such methodologies are the data-adjustment method, which stems from the nuclear energy field, and the data-assimilation method, which is implemented in the geophysical sciences. Both of these methodologies attempt to minimize, in the least-square sense, a user-defined functional that represents the discrepancies between computed and measured model responses. These two methodologies were briefly reviewed and shown to be inconsistent even to first-order in the sensitivities of the …

Rap Traps, Thomas Simmons

Faculty Publications

South Dakota repealed the Rule Against Perpetuities in 1983. The repeal proved to be the seed from which the state's trust industry grew. This article-the first of two linked pieces-begins by surveying the common law version of Rule Against Perpetuities ("RAP"), how it has traditionally been taught, and its labyrinthine, counter-intuitive mechanics. It holds many traps for both the wary and the unwary alike. In the pages which follow, a handful of inadequate contemporary reforms to the rule will be outlined, and the potentially devastating application of the rule to trusts and long-term family wealth planning will be touched upon. …

How Cost-Effective Are Electric Vehicle Subsidies In Reducing Tailpipe-Co2 Emissions? An Analysis Of Major Electric Vehicle Markets, Tamara L. Sheldon, Rubal Dua, Omar Abdullah Alharbi

Faculty Publications

We estimate the cost-effectiveness of plug-in electric vehicle (PEV) subsidies in reducing tailpipe-CO2 emissions in China, the U.S., and nine European countries. We find that the per-tonne cost of tailpipe-CO2 avoided increases linearly with the government-subsidized percentage of the PEV price. Costs are relatively higher in the Netherlands and Denmark, which subsidized high-priced PEVs including plug-in hybrids, and lower in the U.S., where PEVs replaced higher-emissions cars. Chinese PEV subsidies have a short-run static cost of up to $1,600 per tonne, far exceeding the social cost of carbon, suggesting that subsidies are more a part of China’s industrial policy than …

Faculty Publications

This article introduces the VESPACE project, an international, multi-disciplinary digital humanities initiative to build a computer-mediated playable simulation—a video game—of the eighteenth-century Paris Fair theatre. As part of this project, a weeklong postgraduate workshop was convened by the authors in May 2020 to develop protocols and procedures for coding literary and historical data for the Ensemble social physics engine that will govern behaviour of non-player characters (NPCs) in the interactive model. This article lays out the history and theory of social physics, the potential impacts of this project on historiographic practice, and the methodology and outcomes of the workshop week. …

Reconsidering The Good Of Improving Accountability, Roy L. Heidelberg

Faculty Publications

Among the rhetorical pleas that follow most instances of public dissatisfaction is the call for more or better accountability. Accountability is a lauded notion, a “golden concept” that is considered widely as critical to the success of democratic government. Such pleas, I will argue, are misplaced. Rather than starting from the premise of accountability as an idea that no one can be against, I consider the possibility that accountability undermines the very notion it ostensibly promotes: self-government. The concept of accountability in modern political theory is tied more closely to the emergence of an impersonal administrative state than it is …

Prep On Tiktok: Benefits, Barriers, And Possibilities, Joseph Schwartz, Josh Grimm, Cameron Jamison

Faculty Publications

HIV remains a serious problem in the U.S. particularly for men who have sex with men. PrEP is an intervention that can dramatically decrease the risk of HIV infection. Because rates of PrEP adoption have been lower than anticipated, researchers have called for new tactics for promoting PrEP. For this reason, we analyzed PrEP messaging on TikTok. In an analysis guided by the Health Belief Model, we found that discussions of PrEP benefits and barriers were most common on TikTok. Severity and susceptibility were least common. We distilled these findings into suggestions for promoting PrEP adoption.

Effects Of Parent-Implemented Interventions On Outcomes Of Children With Autism: A Meta-Analysis, Wai Man Cheng, Timothy B. Smith, Marshall Butler, Tina Taylor, Devan Clayton

Faculty Publications

Children with autism spectrum disorder (ASD) have been shown to beneft from parent-implemented interventions (PIIs). This meta-analysis improved on prior reviews of PIIs by evaluating RCTs and multiple potential moderators, including indicators of research quality. Fifty-one efect sizes averaged moderately strong overall benefts of PIIs (g=0.553), with studies having lower risk of research bias yielding lower estimates (g=0.47). Parent and observer ratings yielded similar averaged estimates for positive behavior/social skills (g=0.603), language/communication (g=0.545), maladaptive behavior (g=0.519), and to a lesser extent, adaptive behavior/life skills (g=0.239).

This study examined college students’ perspectives about contraception and abortion in the context of the United States Supreme Court’s decision to eliminate the constitutional right to abortion in June 2022. Individual, semi-structured interviews were conducted between October 2022 and February 2023 with a convenience sample of 20 college students, ages 18–22, attending a public university in the southeastern United States. Qualitative data analysis revealed three main themes. First, most participants conveyed fear, dismay, and anger about the decision in Dobbs v. Jackson Women’s Health Organization to overturn Roe v. Wade and a few expressed concerns about potential restrictions on contraception. …

U.S. Travelers’ Perceived Image Of Latin America As Their Future Travel Destination, Maricela I. Montes-Guerra, Natalia Zapata-Cuervo, Miyoung Jeong

Faculty Publications

This study identified U.S. travelers’ perceptions toward Latin America as their future place to visit, based on their perceived destination attributes, activities, and overall affective image. Selecting nine attractive destinations, this study aimed, first, to develop U.S. travelers’ perceptual mapping of countries by using destination image attributes and activities, second, to determine comparative strengths and weaknesses, and third, to propose destination marketing strategies that will derive U.S. travelers' attention to the country. Overall, Americans have favorable affective image toward the nine tourism destinations in Latin America. Costa Rica was respondents’ most preferred country to visit, followed by Peru and Brazil.

Lidar-Change-Based Mapping Of Sediment Movement From An Extreme Rainfall Event, Silvia E. Piovan, Michael E. Hodgson, Paolo Mozzi, Dwayne E. Porter, Bryan Hall

Faculty Publications

Mapping landscape change at fine scales (e.g. < 1.0 m resolution) using airborne LiDAR data from manned aircraft is a significant challenge. This challenge is magnified in disaster response contexts. A combination of collection and processing factors contributes to horizontal and vertical errors (and resulting uncertainty) in each pre- and post-LiDAR derived digital elevation model (DEM). Subsequently, the errors in the change surface from the two (or more) DEMs are an accumulation of the errors in the individual DEMs. Thus, reliable mapping erosion/deposition changes at sub-meter precision in change detection studies using LiDAR data is largely the domain of terrestrial LiDAR or sUAS with LiDAR scanners rather than manned aircraft. Unfortunately, terrestrial and sUAS LiDAR scanners are not well suited for mapping large areas and sUAS collections are subject to additional airspace constraints compared to manned aircraft. In this study, we probed one of the significant issues in airborne LiDAR change projects–vertical height errors from sequential flight lines. A simplified solution for determining flight line vertical biases in areas of low topographic relief with natural cover types was developed and tested for normalizing point clouds. The approach was tested in a fine-scale erosion/deposition study from an extreme rainfall event that eroded and deposited sand at depths of about 1.0 m. Airborne LiDAR had been collected prior to the rainfall event, and another airborne LiDAR collection was made 1 month after the event. Eleven field campaigns to collect reference data and visit anomalies in the change surface were conducted in a 15-month period after the event, beginning 25 February 2016 and ending 8 May 2017. The validation results indicate accuracies for the pre-event and post-event LiDAR derived DEMs were 7.8 cm and 13.0 cm RMSE, respectively. After modeling vertical errors and corrections applied to the post-event point clouds, the RMSE for the post-event DEM was 8.3 cm. In the depositional use case, 27 locations were sampled with auger boreholes/sand pits and compared with LiDAR-based change. The LiDAR-based change detection analysis resulted in predicted sand depth accuracies of 94% with a mean error of 4.7 cm.

A Russian Gil Blas, Or The Adventures Of Prince Gavrilo Simonovich Chistyakov, Vasily Trofimovich Narezhny, Ronald D. Leblanc (Translator)

Faculty Publications

Although Vasily Trofimovich Narezhny (1780-1825) is generally considered to be one of the pioneers of the modern novel in Russia, his works have yet to be sufficiently recognized for their many artistic merits. He receives little critical attention in most histories of the rise of the novel in early nineteenth-century Russia. Born in Ukraine, but educated in Moscow, Narezhny wrote lengthy satirical novels imbued with a sardonic tone and an earthy brand of realism that tended to offend the refined aesthetic sensibilities of many contemporary followers of Nikolai Karamzin and his dominant school of literary Sentimentalism during the early years …

Mysterizing Religion, Marc O. Degirolami

Faculty Publications

(Excerpt)

A mystery of faith is a truth of religion that escapes human understanding. The mysteries of religion are not truths that human beings happen not to know, or truths that they could know with sufficient study and application, but instead truths that they cannot know in the nature of things. In the Letter to the Colossians, St. Paul writes that as a Christian apostle, his holy office is to “bring to completion for you the word of God, the mystery hidden from ages and from generations past.” Note that Paul does not say that his task is to make …

A year since the declaration of the global coronavirus disease 2019 (COVID-19) pandemic, there were over 110 million cases and 2.5 million deaths. Learning from methods to track community spread of other viruses such as poliovirus, environmental virologists and those in the wastewater-based epidemiology (WBE) field quickly adapted their existing methods to detect SARS-CoV-2 RNA in wastewater. Unlike COVID-19 case and mortality data, there was not a global dashboard to track wastewater monitoring of SARS-CoV-2 RNA worldwide. This study provides a 1-year review of the “COVIDPoops19” global dashboard of universities, sites, and countries monitoring SARS-CoV-2 RNA in wastewater. Methods to …

The Impact Of Audit Technology On Audit Task Outcomes: Evidence For Technology-Based Audit Techniques, Marc Eulerich, Adi Masli, Jeffrey Pickerd, David A. Wood

Faculty Publications

As audit technology becomes more widespread, practice and academia are raising concerns about the costs and benefits of these technologies. We examine how internal auditors use technologybased audit techniques (TBATs) and how TBATs impact the efficiency and effectiveness of their audits. We use two surveys and interviews of individual auditors and chief audit executives (CAE) to examine their perceptions of TBATs. Auditors perceive TBATs as beneficial. Specifically, an increase in the use of TBATs is associated with completing more audits, finding more risk factors, providing more recommendations, and decreasing audit days. However, CAEs also perceive TBATs to be costly. An …

Discussion Of "Why Can’T I Trade? Exchange Discretion In Calling Halts", Michael S. Drake

Faculty Publications

Liquidity is an important feature of well-functioning capital markets. While many market frictions exist that constrain liquidity, none are as dramatic as trading halts when trading is suspended altogether. Trading halts became a common feature of US securities markets in the aftermath of Black Monday (October 19, 1987). The hope of regulators was that system-wide trading halts, so-called market circuit breakers, would decrease the likelihood of dramatic sell-offs by allowing markets to cool off. Regulators further argued that security-specific trading halts implemented in advance of a material news release could also reduce volatility and help level the playing field between …

Multiple-Choice Reading Behaviors Of Esl Students: An Eye-Tracking Study, Juan Escalante, Grant Eckstein, Troy L. Cox, Steven Luke

“Someone In Their Corner”: Parental Support In Online Secondary Education, Courtney N. Hanny, Charles R. Graham, Richard E. West, Jered Borup

Faculty Publications

Despite increased interest in K–12 online education, student engagement deficits and the resulting student attrition remain widespread issues. The Academic Communities of Engagement (ACE) framework theorizes that two groups support online student engagement: the personal community of support and the course community of support. However, more evidence is needed to understand how members of these communities, especially parents, support students in various contexts. Using insights gleaned from 14 semi-structured interviews of parents with students enrolled in online secondary school, this study adds support to the roles identified in the ACE framework by presenting real examples of parents supporting their online …

Barriers And Enablers To K-12 Blended Teaching, Courtney N. Hanny, Karen T. Arnesen, Qi Guo, Jordan Hansen, Charles R. Graham

Faculty Publications

The attributes of post-pandemic blended teaching (BT) will more closely resemble pre-Coronavirus conditions than the outbreak’s emergency remote teaching. Thus, barriers and enablers for teachers transitioning to BT after emergency remote teaching will be similar to those of early BT adopters. K-12 research has identified external and internal barriers and enablers to technology integration but has largely overlooked those of BT. This study involved analyzing 62 interviews of K-12 blended teachers to discover factors that enabled BT, stood as barriers to initial and continued blending efforts, and helped teachers overcome barriers. Teacher-perceived barriers included, among others, costs perceived as outweighing …
