Pedagogy, Performativity And ‘Never Again’: Staging Plays From The Terezín Ghetto, Lisa Peschel, Alan Sikes

Faculty Publications

As collaborators on the project Performing the Jewish Archive we worked with students in the US and in the UK to devise two separate peformances based on a script from the Terezín Ghetto (in German, Theresienstadt) titled Comedy about a Trap. By developing with them what we call ‘co-textual’ scenes, we engaged in a type of performance pedagogy that we hope will achieve lasting transformation: the students created and performed a relationship between the script, their new knowledge of the past and their own views in the present, leading to transformative insights regarding the lives of the prisoners and the …

Measuring The Multidimensional Construct Of Pornography: A Long And Short Version Of The Pornography Usage Measure, Dean M. Busby, Brian J. Willoughby, Hsin-Yao Chiu, Joseph A. Olsen

Faculty Publications

With the increase in the availability and usage of pornography, the research on the effects of pornography has also increased. This research has uncovered several controversies in the field regarding how pornography usage influences attitudes, sexual behaviors, and relationships. However, many of the measures of pornography are problematic as there is often little reliability and validity information for them and it is not clear that participants in these research studies are referring to the same types of materials when they answer pornography usage questions. Consequently, many of the research findings are suspect and it is crucial to develop reliable and …

Efficacy Of Entomopathogenic Nematodes Against The Sugarbeet Wireworm, Limonius Californicus (Mannerheim) (Coleoptera: Elateridae), Ramandeep Kaur Sandhi, David Shapiro-Ilan, Anamika Sharma, Gadi V.P. Reddy

Faculty Publications

Wireworms, the larval stage of click beetles (Coleoptera: Elateridae), are economically important soil-dwelling pests that attack many field crops worldwide. Wireworms have become a serious threat to spring wheat in the Northern Great Plains because of lack of effective control measures, creating a need for alternative control methods such as biological control with entomopathogenic nematodes (EPNs). A laboratory bioassay was used to test ten EPN strains and identify infective EPN strains against the sugarbeet wireworm, Limonius californicus (Mannerheim) (Coleoptera: Elateridae). Steinernema carpocapsae (Weiser) (All and Cxrd strains) and S. riobrave Cabanillas, Poinar, and Raulston (355 and 7–12 strains) killed 60–70% …

A New Proposal For The M + A Methodology In Segregating Populations Of Cowpea, Renata Fernandes De Matos, Antônio Moreira Barroso Neto, Júlio César Dovale, Cândida Hermínia Campos De Magalhães Bertini, Roberto Fritsche-Neto

Faculty Publications

The evaluation of segregating populations in plant breeding programs is an onerous and time-consuming process. Early identification of populations with genetic potential can be done by m + a methodology. However, the possibility of a modification in the traditional methodology in order to make it more efficient, that is, faster and cheaper, was envisaged. Thus, the objective of this study was to compare the genetic gains obtained by both methodologies, the traditional one and the proposed modification. For this, ten segregating bean-cowpea populations were evaluated at two distinct levels of homozygous F3:4 and F3:5. Genetic values were predicted by two …

How To Encourage Volunteers In The Church, S. Joseph Kidder

Faculty Publications

In the previous two articles, we dealt with how to recruit and train volunteers. The success of your church’s mission depends on people who follow Jesus and are passionate about His mission in the church and in the world. Now that you’ve recruited leaders for your ministry, the best part begins: encouraging them and building relationships with them to help them grow in their faith and spiritual gifts.

Decarbonization In Democracy, Shelley Welton

Faculty Publications

Conventional wisdom holds that democracy is structurally ill-equipped to confront climate change. As the story goes, because each of us tends to dismiss consequences that befall people in other places and in future times, “the people” cannot be trusted to craft adequate decarbonization policies, designed to reduce present-day, domestic carbon emissions. Accordingly, U.S. climate change policy has focused on technocratic fixes that operate predominantly through executive action to escape democratic politics — with vanishingly little to show for it after a change in presidential administration.

To help craft a more durable U.S. climate change strategy, this Article scrutinizes the purported …

This Article reviews the status of selected contemporary peace processes in the early stages of the COVID-19 outbreak and explores some of the initial effects that the pandemic has had on those processes. The Article first provides an overview of the 20th and 21st century trend toward internationalized peace processes. Then, it introduces several contemporary mediation efforts that were ongoing at the onset of the pandemic and examines the early impacts of COVID-19 on those peace processes. In so doing, the Article identifies instances where actors have exploited the pandemic and peace processes where momentum has shrunk under COVID-19. …

Applying Control Abstraction To The Design Of Human–Agent Teams, Clifford D. Johnson, Michael E. Miller, Christina F. Rusnock, David R. Jacques

Faculty Publications

Levels of Automation (LOA) provide a method for describing authority granted to automated system elements to make individual decisions. However, these levels are technology-centric and provide little insight into overall system operation. The current research discusses an alternate classification scheme, referred to as the Level of Human Control Abstraction (LHCA). LHCA is an operator-centric framework that classifies a system’s state based on the required operator inputs. The framework consists of five levels, each requiring less granularity of human control: Direct, Augmented, Parametric, Goal-Oriented, and Mission-Capable. An analysis was conducted of several existing systems. This analysis illustrates the presence of each …

Single-Pulse, Kerr-Effect Mueller Matrix Lidar Polarimeter, Keyser, Christian K., Richard K. Martin, Helena Lopez-Aviles, Khanh Nguyen, Arielle M. Adams, Demetrios Christodoulides

Faculty Publications

We present a novel light detection and ranging (LiDAR) polarimeter that enables measurement of 12 of 16 sample Mueller matrix elements in a single, 10 ns pulse. The new polarization state generator (PSG) leverages Kerr phase modulation in a birefringent optical fiber, creating a probe pulse characterized by temporally varying polarization. Theoretical expressions for the Polarization State Generator (PSG) Stokes vector are derived for birefringent walk-off and no walk-off and incorporated into a time-dependent polarimeter signal model employing multiple polarization state analyzers (PSA). Polarimeter modeling compares the Kerr effect and electro-optic phase modulator–based PSG using a single Polarization State Analyzer …

Seasonal Patterns Of Surface Inorgamic Carbon System Variables In The Gulf Of Mexico Inferred From A Regional High-Resolution Ocean Biogeochemical Model, Fabian A. Gomez, Rik Wanninkhof, Leticia Barbero, Sang Ki Lee, Frank J. Hernandez

Faculty Publications

Uncertainties in carbon chemistry variability still remain large in the Gulf of Mexico (GoM), as data gaps limit our ability to infer basin-wide patterns. Here we configure and validate a regional high-resolution ocean biogeochemical model for the GoM to describe seasonal patterns in surface pressure of CO₂ (pCO₂), aragonite saturation state (ΩAr), and sea–air CO₂ flux. Model results indicate that seasonal changes in surface pCO₂ are strongly controlled by temperature across most of the GoM basin, except in the vicinity of the Mississippi–Atchafalaya river system delta, where runoff largely controls dissolved inorganic carbon (DIC) …

Faculty Publications

Background: We evaluated smokers’ perceptions of heated tobacco products (HTPs) in Mexico, where industry publically lobbied to introduce HTPs into this country that banned both HTPs and e-cigarettes. Methods: Online surveys (November 2018 to July 2019) were analyzed from adults who only smoked cigarettes (n = 2091) or who smoked and used e-cigarettes (“dual users” n = 1128). Logistic models regressed HTP awareness, interest to trying HTPs, and having seen HTPs for sale (only among aware participants) on sociodemographics and tobacco-related variables. Results: Of the 17.1% who were aware of HTPs, 52.7% reported having seen HTPs for sale. Of all …

Developing Outreach Events That Impact Underrepresented Students: Are We Doing It Right?, Andrew J. Gall, Peter J. Vollbrecht, Tristan Tobias

Faculty Publications

Many outreach programs share the common goals of serving underrepresented groups in STEM and improving public attitudes toward science. To meet these goals, scientists must find ways to both reach the appropriate audience and communicate the importance of science in meaningful and accessible ways. This requires careful consideration of the outreach method being used. Two common outreach methods include in‐school visits (scientist in the classroom) and science fairs or open houses. Here, we compare the effectiveness of these two outreach methods in meeting the goals of reaching underrepresented students and/or students with less initial interest in science. We have found …

Supreme Court Journalism: From Law To Spectacle?, Barry Sullivan, Cristina Carmody Tilley

Faculty Publications

Few people outside certain specialized sectors of the press and the legal profession have any particular reason to read the increasingly voluminous opinions through which the Justices of the Supreme Court explain their interpretations of the Constitution and laws. Most of what the public knows about the Supreme Court necessarily comes from the press. That fact raises questions of considerable importance to the functioning of our constitutional democracy: How, for example, does the press describe the work of the Supreme Court? And has the way in which the press describes the work of the Court changed over the past several …

Understanding Fluid Dynamics From Langevin And Fokker–Planck Equations, Andrei Medved, Riley Davis, Paula A. Vasquez

Faculty Publications

The Langevin equations (LE) and the Fokker–Planck (FP) equations are widely used to describe fluid behavior based on coarse-grained approximations of microstructure evolution. In this manuscript, we describe the relation between LE and FP as related to particle motion within a fluid. The manuscript introduces undergraduate students to two LEs, their corresponding FP equations, and their solutions and physical interpretation.

Porous Silica Nanotube Thin Films As Thermally Insulating Barrier Coatings, Derric B. Syme, Jason M. Lund, Brian D. Jensen, Robert C. Davis, Richard R. Vanfleet, Brian D. Iverson

Faculty Publications

The fabrication and examination of a porous silica thin film, potentially for use as an insulating thin film, were investigated. A vertically aligned carbon nanotube (CNT) forest, created by chemical vapor deposition (CVD), was used as scaffolding to construct the porous film. Silicon was deposited on the CNT forest using low-pressure CVD (LPCVD) and then oxidized to remove the CNTs and convert the silicon to silica for electrical or thermal passivation (e.g., thermal barrier). Thermal conductivity was determined using a 1D heat-transfer analysis that equated radiative heat loss in a vacuum with conduction through the substrate and thin film stack. …

Traditional Funeral And Burial Rituals And Ebola Outbreaks In West Africa: A Narrative Review Of Causes And Strategy Interventions, Chulwoo Park

Faculty Publications

Introduction: In West Africa, traditional funerals and burials have proven main contributors to the spread of infectious diseases, such as Ebola, plague, the Marburg virus, and others. Although the World Health Organization has provided guidelines for the safe burial process after learning of the culture of the afterlife in Ebola-affected areas, little effort has been made to integrate theoretical interventions and models for changing West Africans’ funeral behavior. This research was conducted to study 1) the background of traditional burial rituals, 2) interventions to contain Ebola outbreaks in West Africa, and 3) a strategic approach to future disease outbreak in …

Inhibiting Iron Mobilization From Bacterioferritin In Pseudomonas Aeruginosa Impairs Biofilm Formation Irrespective Of Environmental Iron Availability, Anabel Soldano, Huili Yao, Josephine R. Chandler, Mario Rivera

Faculty Publications

Copyright © 2020 American Chemical Society. Although iron is essential for bacteria, the nutrient presents problems of toxicity and solubility. Bacteria circumvent these problems with the aid of iron storage proteins where Fe3+ is deposited and, when necessary, mobilized as Fe2+ for metabolic requirements. In Pseudomonas aeruginosa, Fe3+ is compartmentalized in bacterioferritin (BfrB), and its mobilization as Fe2+ requires specific binding of a ferredoxin (Bfd) to reduce the stored Fe3+. Blocking the BfrB-Bfd complex leads to irreversible iron accumulation in BfrB and cytosolic iron deprivation. Consequently, given the intracellular iron sufficiency requirement for biofilm development, we hypothesized that blocking the …

Apology And Restitution: The Psychophysiology Of Forgiveness After Accountable Relational Repair Responses, Charlotte Vanoyen-Witvliet, Lindsey M. Root Luna, Everett L. Worthington Jr., Jo-Ann Tsang

Faculty Publications

Apology and restitution each represents wrongdoers’ accountable repair responses that have promoted victims’ self-reported empathy and forgiveness in crime scenario research. The current study measured emotional and stress-related dependent variables including physiological measures, to illuminate the links between predictors of forgiveness and health-relevant side effects. Specifically, we tested the independent and interactive effects of apology and restitution on forgiveness, emotion self-reports, and facial responses, as well as cardiac measures associated with stress in 32 males and 29 females. Apology and restitution each independently increased empathy, forgiveness, gratitude, and positive emotions, while reducing unforgiveness, negative emotion, and muscle activity above the …

Listeria Monocytogenes Response To Anaerobic Environments, Brandy N. Roberts, Damayanti Chakravarty, J.C. Gardner Iii, Steven C. Ricke, Janet R. Donaldson

Faculty Publications

Listeria monocytogenes is a Gram-positive facultative anaerobic bacterium that is responsible for the disease, listeriosis. It is particularly lethal in pregnant women, the fetus, the elderly and the immunocompromised. The pathogen survives and replicates over a wide range of temperatures (4 to 42 °C), pH, salt and oxygen concentrations. Because it can withstand various environments, L. monocytogenes is a major concern in food processing industries, especially in dairy products and ready-to-eat fruits, vegetables and deli meats. The environment in which the pathogen is exposed can influence the expression of virulence genes. For instance, studies have shown that variations in oxygen …

Hyaluronic Acid-Cellulose Composites As Patches For Minimizing Bacterial Infections, Kelsey M. Lopez, Sudhir Ravula, Rocío L. Pérez, Caitlan E. Ayala, Jack N. Losso, Marlene E. Janes, Isiah M. Warner

Faculty Publications

Copyright © 2020 American Chemical Society. A facile method was used to synthesize biocomposites containing differing ratios of hyaluronic acid (HA) and cellulose (CEL). Based on the properties of the individual polymers, the resultant composite materials may have potentially great wound care properties. In the method outlined here, 1-butyl-3-methylimidazolium chloride ([Bmim][Cl]), a simple ionic liquid, was used as the sole solvent without chemical modifiers to dissolve the biopolymers at ratios of 1:1 and 2:1 HA to CEL. This method was completely recyclable since the ionic liquid, [Bmim][Cl], can be recovered. Results from spectroscopic measurements [Fourier transform infrared (FT-IR) and X-ray …

Mirror, Mirror On The Wall: The Effect Of Listening To Body Positive Music On Implicit And Explicit Body Esteem, Sarah M. Coyne, Emilie J. Davis, Wayne Warburton, Laura Stockdale, Imogen Abba, Dean M. Busby

Faculty Publications

The current article used 3 studies to examine the impact of listening to body positive music on both explicit and implicit measures of body esteem in women. Study 1 found that women who viewed a mainstream popular body positive music video reported higher levels of body esteem than those who viewed a popular body objectifying music video. In Studies 2 and 3, we wrote and recorded our own songs to keep the musical features apart from the lyrics constant (e.g., rhythm, melody, and singer identity). Study 2 also found that women showed higher levels of implicit (but not explicit) body …

Mincing No Words: When The Court's Opinion Criticizes An Advocate's Writing, Douglas E. Abrams

Faculty Publications

In recent years, court opinions have chastised counsel’s briefs or other written submissions for such structural deficiencies as improper citations; missing exhibit labels; incomplete tables of citations; mis-numbered counts; failure to cite to the record; and skirting of court rules that regulate font size, maximum page limits, mandated margins, and the like. Beyond structure, opinions have also chastised counsel for written submissions that are “riddled with misspellings, typographical errors, punctuation errors, and grammar and usage errors” and for those marked by careless cutting-and-pasting from forms or other prior work product, or by careless reliance on spell-check.

Some opinions identify the …

Low-Phosphate Chromatin Dynamics Predict A Cell Wall Remodeling Network In Rice Shoots, Maryam Foroozani, Sara Zahraeifard, Dong Ha Oh, Guannan Wang, Maheshi Dassanayake, Aaron P. Smith

Faculty Publications

© 2020 American Society of Plant Biologists. All Rights Reserved. Phosphorus (P) is an essential plant macronutrient vital to fundamental metabolic processes. Plant-available P is low in most soils, making it a frequent limiter of growth. Declining P reserves for fertilizer production exacerbates this agricultural challenge. Plants modulate complex responses to fluctuating P levels via global transcriptional regulatory networks. Although chromatin structure plays a substantial role in controlling gene expression, the chromatin dynamics involved in regulating P homeostasis have not been determined. Here we define distinct chromatin states across the rice (Oryza sativa) genome by integrating multiple chromatin marks, including …
