Closed Loop Recycling Of Low Friction Polymers In Fused Granule Fabrication Additive Manufacturing Processes, Neil Thompson, Jason Weaver

Faculty Publications

Plastic waste is a critical worldwide problem that impacts additive manufacturing (AM). Extensive research has explored how plastic waste in AM can be reduced by recycling prints into new filament, with varying success. An alternative to filament-based extrusion is “fused granule fabrication” (FGF), which extrudes from pellets or granules. This method is often used for large area additive manufacturing (LAAM) of polymers. This paper expands upon the knowledge base from previous research on LAAM and examines the extent to which PETG can be recycled and reprinted through the same FGF tool without significant loss to its material properties. The metric …

Reading Rate Gain In A Second Language: The Effect Of Unassisted Repeated Reading And Intensity On Word-Level Reading Measures, Grant Eckstein, Krista Rich, Ethan Lynn

Faculty Publications

Repeated reading is a popular intervention used to help struggling readers by exposing them to the same text multiple times. While the approach has been effective in L1 and some EFL settings, little research has explored its effectiveness compared against a control group or among ESL learners. Our study examined reading rate gains using words per minute and four eye-tracking measures with 46 mid-intermediate ESL learners grouped into three 14-week treatment groups: a control group that read 26 text passages (about two per week) just once through, another that read the same passages twice in each sitting, and a third …

Foundations Of Online Learning: Challenges And Opportunities, Christine Greenhow, Charles R. Graham, Matthew J. Koehler

Faculty Publications

Online learning—learning that involves interactions that are mediated through using digital, typically internet-based, technology—is pervasive, multi-faceted, and evolving, creating opportunities and challenges for educational research in the wake of the COVID-19 pandemic. In this special issue, we advance an interdisciplinary agenda for online learning research at the intersection of educational technology, educational psychology, and the learning sciences. In this first article in the issue, we define online learning including its variants, review historical and current contexts, explore its multidimensionality, and assert key issues shaping contemporary online learning. We propose five important lenses: community, engagement, pedagogy, equity, and design-based research, through …

Antidiscrimination Law Through A Sociolegal Lens, Anna Offit

Faculty Publications

This Symposium invites reflection on whether the Anthropology of Law has “any space left for the content of rules” at a time when the concerns of legal anthropologists have largely shifted to processes, materials, and practices that are “adjacent to law.” Taking the jury system as an illustrative case, this Essay advocates for the relevance and value of the anthropological study of rules, their content, and their effects. Looking in particular at antidiscrimination rules derived from Batson v. Kentucky, decided in 1986, it argues that a sociolegal, ethnographic approach to how lawyers perpetuate discrimination in jury selection offers insight …

A Simple Approach To Better Distinguish Real Earnings Manipulation From Strategy Changes, Theodore E. Christensen, Adrienna Huffman, Melissa F. Lewis-Western, Kristen Valentine

Faculty Publications

Researchers typically infer real earnings management when a firm’s operating and investing activities differ from industry norms. A significant problem with classifying deviations from industry averages as myopic earnings management is that companies can change their operating and investing decisions for strategic business reasons rather than to mislead stakeholders. Using principal components analysis, we systematically evaluate existing measures and develop a comprehensive real activities measure to better capture earnings manipulation. Our measure reflects (i) deviations from industry averages across multiple activities and (ii) other signals of manipulation. This approach is promising because, although there are many sources of abnormal activities, …

Dissent And Legitimacy In International Criminal Law, Nancy Armoury Combs

Faculty Publications

Throughout history, dissenting opinions have been subject to soaring praise as well as vitriolic criticism. Although some commentators nominally acknowledge that the normative value of dissenting opinions necessarily varies depending on the unique context in which the relevant court operates, in fact, we see the same arguments advanced to support or oppose dissenting opinions, regardless of the court in which those opinions appear. Dissents are particularly prevalent in international criminal courts--those courts established to prosecute the worst crimes known to humankind: genocide, war crimes, and crimes against humanity. Although dissents in these courts have garnered little scholarly attention, the few …

Fundamental Criminal Procedure (2022 Edition), Fredric I. Lederer

Faculty Publications

Fundamental Criminal Procedure explores American criminal procedure in a format ultimately destined for electronic publication. Because many students devote a great deal of their class time to taking notes, often at the expense of creative analysis, the text is intended to supply all of the necessary “black letter law” needed for mastery of the subject. The materials are, however, far more than a “study aid.” They emphasize where appropriate the crucial philosophical and policy questions and issues inherent in the subject. Periodic “Review Questions” require understanding application of academic material in a pragmatic context. “Legal Briefs” require the student to …

#Metoo And The Process That's Due: Sexual Misconduct Where We Live, Work, And Learn, Nicole Buonocore Porter

Faculty Publications

The #MeToo movement has been instrumental in bringing attention to the pervasiveness of sexual harassment and sexual assault (collectively, sexual misconduct) in all walks of life and in all environments, including at work, school, home, and out in public. But the movement has also brought with it a great deal of confusion about how we define sexual misconduct and whether and when legal liability attaches. Part of the confusion can be blamed on the fact that at least three discrete areas of law can possibly apply to sexual misconduct—criminal law, Title VII (when the sexual misconduct takes place in the …

Salt, Smurthwaite, And Smith: The Origins Of The Modern Legal Identity Of The Church Of Jesus Christ Of Latter-Day Saints, Nathan B. Oman

Faculty Publications

In 2019 there existed a legal entity known as The Church of Jesus Christ of Latter-day Saints. This fact will likely strike most readers as unexceptional. More interesting, however, prior to 2019 there had been no such legal entity as the Church of Jesus Christ of Latter-day Saints for over 150 years, the last of that name likely having been disincorporated in 1862. Even more strangely, although there were millions of people around the globe who identified themselves as Latter-day Saints, in 2019 the only member of the legal entity known as The Church of Jesus Christ of Latter-day Saints …

The Most Dangerous Branch Of Science? Reining In Rogue Research And Reckless Experimentation In Social Services, James G. Dwyer

Faculty Publications

Most people are unaware how much public policy is either lacking in any empirical-research support or driven by bad research. Political actors motivated by ideology or donor/constituent demands propose new government practices—in areas ranging from policing to funding of treatments for gender dysphoria in youth to welfare-qualification rules—that will greatly impact people’s lives, and if anyone asks what basis they have for thinking the impact will be good, they can readily find some study to support their case. Especially when powerless populations are put at risk, neither the legislative process nor peer review in the publication process provides a real …

State Rejection Of Federal Law, Thomas B. Bennett

Faculty Publications

Sometimes the United States Supreme Court speaks, and states do not follow. For example, in 2003, the Arizona Supreme Court agreed to "reject" a decision of the U.S. Supreme Court, because no "sound reasons justif[ied] following" it. Similarly, in 2006, Michigan voters approved a ballot initiative that, according to the legislature that drafted it, sought "at the very least to freeze' the state's ... law to prevent" state courts from following a ruling of the U.S. Supreme Court. Surprising though this language may be, there is nothing nefarious about these cases. Cooper v. Aaron this is not. Unlike more notorious …

Courts As Auditors Of Legislation?, Daniel Pi, Giampaolo Frezza, Francesco Parisi

Faculty Publications

Sources of law vary greatly across geography and human history. Some legal systems identify democratic lawmaking with political deliberation, while others rely on judicial process and judge-made law. This Essay argues that the normative problem of determining a hierarchy of legal sources may be usefully understood in terms of mechanism design, and that legislation and judicial precedent operate complementarily. If the ultimate policy objective is to create legal rules that reflect the "will of the people," judge-made law can function as an audit on the rules promulgated by elected legislatures. The two sources of law, working in conjunction, thereby correct …

‘Big’ And ‘Little’ Quo Vadis? In The United States, 1913–1916: Using Gis To Map Rival Modes Of Feature Cinema During The Transitional Era, Jeffrey Klenotic

Faculty Publications

This article emanates from a geospatial database of over 600 premieres of the Cines company’s Quo Vadis? (1913), an eight-reel film distributed by George Kleine, and nearly 250 premieres of the Quo Vadis Film Company’s Quo Vadis? (1913), a three-reel film of ambiguous origins distributed by Paul De Outo. By mapping local premieres of both films across the United States from 1913 through 1916, the data show with spatiotemporal precision the spread of Quo Vadis? as one of cinema’s early blockbuster titles. Yet within this national phenomenon, the two films’ footprints reveal differing cultural geographies served by competing efforts to …

Darius Andrews Of Sumner, Maine: A Descent From Henry Andrews Of Taunton, Massachusetts, Kathrine C. Aydelott

Faculty Publications

This genealogical article proposes a descent from Henry Andrews, one of the proprietors of Taunton, Bristol County, Massachusetts, through Ebenezer Andrews, Jr. to Darius Andrews of Sumner, Oxford County, Maine. It aims to resolve errors, identify gaps in the records, and re-establish identities lost to poor record keeping, misattribution, and confusion.

State-Level Policy Environments, Discrimination, And Victimization Among Sexual And Gender Minority People, Kristen D. Clark, Mitchell R. Lunn, Eliot M. Lev, Michael A. Trujillo, Micah E. Lubensky, Matthew R. Capriotti, Thomas J. Hoffmann, Juno Obedin-Maliver, Annesa Flentje

Faculty Publications

Legislation has been passed in some states to reduce discrimination and victimization toward sexual and gender minority people (SGM; people who are not solely heterosexual and/or whose gender identity is not equal to what is socially associated with sex assigned at birth). The purpose of these analyses is to test whether state-level policy environments are associated with past-year discrimination and victimization among SGM people. Cross-sectional data from The Population Research in Identity and Disparities for Equality (PRIDE) Study annual questionnaire (collected 2018–2019), a national study of the health of SGM adults in the USA, were used for these analyses. Measures …

Guesswork With Quantum Side Information, Eric P. Hanson, Vishal Katariya, Nilanjana Datta, Mark M. Wilde

Faculty Publications

What is the minimum number of guesses needed on average to guess a realization of a random variable correctly The answer to this question led to the introduction of a quantity called guesswork by Massey in 1994, which can be viewed as an alternate security criterion to entropy. In this paper, we consider the guesswork in the presence of quantum side information, and show that a general sequential guessing strategy is equivalent to performing a single quantum measurement and choosing a guessing strategy based on the outcome. We use this result to deduce entropic one-shot and asymptotic bounds on the …

The Contributions Of Immediate Retrieval And Spaced Retrieval To Word Learning In Preschoolers With Developmental Language Disorder, Laurence B. Leonard, Justin B. Kueser, Patricia Deevy, Eileen Haebig, Jeffrey D. Karpicke, Christine Weber

Faculty Publications

Background and Aims: Children with developmental language disorder (DLD) benefit from word learning procedures that include a mix of immediate retrieval and spaced retrieval trials. In this study, we examine the relative contribution of these two types of retrieval.

Methods: We examine data from Haebig et al. (2019) in their study that compared an immediate retrieval condition and a condition of spaced retrieval that also included immediate retrieval trials. Participants were 4- and 5-year old children with DLD and same-age peers with typical language development. Each child learned novel (made-up) words referring to unusual plants and animals in both conditions. …

A Triple Threat: The Parastagonospora Nodorum Sntox267 Effector Exploits Three Distinct Host Genetic Factors To Cause Disease In Wheat, Jonathan K. Richards, Gayan K. Kariyawasam, Sudeshi Seneviratne, Nathan A. Wyatt, Steven S. Xu, Zhaohui Liu, Justin D. Faris, Timothy L. Friesen

Faculty Publications

Parastagonospora nodorum is a fungal pathogen of wheat. As a necrotrophic specialist, it deploys effector proteins that target dominant host susceptibility genes to elicit programmed cell death (PCD). Here we identify and functionally validate the effector targeting the host susceptibility genes Snn2, Snn6 and Snn7. We utilized whole-genome sequencing, association mapping, gene-disrupted mutants, gain-of-function transformants, virulence assays, bioinformatics and quantitative PCR to characterize these interactions. A single proteinaceous effector, SnTox267, targeted Snn2, Snn6 and Snn7 to trigger PCD. Snn2 and Snn6 functioned cooperatively to trigger PCD in a light-dependent pathway, whereas Snn7-mediated PCD functioned in a light-independent pathway. Isolates harboring …

A Longitudinal Investigation Of The Semantic Receptive-Expressive Gap In Spanish-English Bilingual Children, Todd A. Gibson, Elizabeth D. Peña, Lisa M. Bedore, Kevin S. Mccarter

Faculty Publications

Although a semantic receptive-expressive gap appears to be a universal feature of early bilingualism, little is known about its development. We sought to determine if the magnitude of the discrepancy between receptive and expressive standard scores changed over time in bilingual children’s two languages. In this longitudinal study, standardized receptive and expressive semantics tests of 106 Spanish-English bilingual children with TD were taken at kindergarten and first grade in both English and Spanish. We used a multivariate analysis approach to identify interactions and main effects. Although both receptive and expressive standard scores improved across the year in both languages, the …

Effects Of Testing And Disclosing Ancestry-Specific Genetic Risk For Kidney Failure On Patients And Health Care Professionals: A Randomized Clinical Trial, Girish N. Nadkarni, Kezhen Fei, Michelle A. Ramos, Diane Hauser, Emilia Bagiella, Stephen B. Ellis, Saskia Sanderson, Stuart A. Scott, Tatiana Sabin, Ebony Madden, Richard Cooper, Martin Pollak, Neil Calman, Erwin P. Bottinger, Carol R. Horowitz

Faculty Publications

Importance: Risk variants in the apolipoprotein L1 (APOL1 [OMIM 603743]) gene on chromosome 22 are common in individuals of West African ancestry and confer increased risk of kidney failure for people with African ancestry and hypertension. Whether disclosing APOL1 genetic testing results to patients of African ancestry and their clinicians affects blood pressure, kidney disease screening, or patient behaviors is unknown. Objective: To determine the effects of testing and disclosing APOL1 genetic results to patients of African ancestry with hypertension and their clinicians. Design, Setting, and Participants: This pragmatic randomized clinical trial randomly assigned 2050 adults of African ancestry with …

Price Response Of The High Fructose Corn Syrup Industry In The United States: A Bertrand Model Application, Pablo A. Garcia-Fuentes, P. Lynn Kennedy, Gustavo F.C. Ferreira

Faculty Publications

This paper uses a Bertrand duopoly model application and derives a high fructose corn syrup (HFCS) price reaction function that shows the response of the price of HFCS to changes in the price of sugar. It conducts cointegration analysis and assesses the performance of the HFCS price reaction model by estimating a Dynamic Ordinary Least-Squares model. It finds that the prices of HFCS-55, sugar, and corn are cointegrated over the period 1981:1 to 2017:12. The estimated long-run relationship shows that a one percent increase in the price of sugar increases the price of HFCS-55 by 0.19 percent. Additionally, the price …

Alternative Nesting Strategies Of Polistine Wasps In A Subtropical Locale, Scott Nacko, Mark A. Hall, Gregg Henderson

Faculty Publications

Phylogenetic studies suggest that historically all paper wasps (Vespidae: Polistinae) in North America have tropical origins, but some species have adapted to survive temperate conditions. Subtropical climates, which are intermediate between temperate and tropical, allow a unique opportu-nity to study ancestral traits which can be retained or lost within populations, and ultimately elucidate the process of social wasp evolution. We investigated the phenology of paper wasps at study sites in subtropical Baton Rouge, USA, through nest searching and monitoring of nest parameters throughout the warm season (March–October). Across the year, two periods of nest initiation occurred: from March–May (early season …

Inference On Moderation Effect With Third-Variable Effect Analysis–Application To Explore The Trend Of Racial Disparity In Oncotype Dx Test For Breast Cancer Treatment, Qingzhao Yu, Lu Zhang, Xiaocheng Wu, Bin Li

Faculty Publications

Third variable effect refers to the effect from a third variable that explains an observed relationship between an exposure and an outcome. Depending on whether there is causal relationship, typically, a third variable takes the format of a mediator or a confounder. A moderation effect is a special case of the third-variable effect, where the moderator and other variables have an interactive effect on the outcome. In this paper, we extend the R package ‘mma’ for moderation analysis so that third-variable effects can be reported at different levels of the moderator. The proposed moderation analysis use tree-structured models to automatically …

Racial Discrimination And Hazardous Drinking Among Black Drinkers: The Role Of Social Anxiety In The Minority Stress Model, Julia D. Buckner, Nina I. Glover, Justin M. Shepherd, Michael J. Zvolensky

Faculty Publications

Objective: Black Americans who consume alcohol experience worse alcohol-related outcomes. Thus, identifying psycho-sociocultural factors that play a role in hazardous drinking among Black individuals is vital to informing prevention and treatment efforts to reduce these disparities. Racial discrimination is related to hazardous drinking among Black adults, suggesting that some may drink (and continue to drink despite drinking-related problems) to alleviate negative affect (e.g., depression, anxiety) associated with discrimination. Yet, despite the social nature of both racial discrimination and drinking, no known research has examined the role of social anxiety in the relations among racial discrimination experiences and hazardous drinking. Method: …

Monitoring Leaf Phenology In Moist Tropical Forests By Applying A Superpixel-Based Deep Learning Method To Time-Series Images Of Tree Canopies, Guangqin Song, Shengbiao Wu, Calvin K.F. Lee, Shawn P. Serbin, Brett T. Wolfe, Michael K. Ng, Kim S. Ely, Marc Bogonovich, Jing Wang, Ziyu Lin, Scott Saleska, Bruce W. Nelson, Alistair Rogers, Jin Wu

Faculty Publications

Tropical leaf phenology—particularly its variability at the tree-crown scale—dominates the seasonality of carbon and water fluxes. However, given enormous species diversity, accurate means of monitoring leaf phenology in tropical forests is still lacking. Time series of the Green Chromatic Coordinate (GCC) metric derived from tower-based red–greenblue (RGB) phenocams have been widely used to monitor leaf phenology in temperate forests, but its application in the tropics remains problematic. To improve monitoring of tropical phenology, we explored the use of a deep learning model (i.e. superpixel-based Residual Networks 50, SP-ResNet50) to automatically differentiate leaves from non-leaves in phenocam images and to derive …

Perceptions Of Purpose, Cohesion, And Military Leadership: A Path Analysis Of Potential Primary Prevention Targets To Mitigate Suicidal Ideation, Benjamin Trachik, Emma H. Moscardini, Michelle L. Ganulin, Jen L. Mcdonald, Ashlee B. Mckeon, Raymond P. Tucker, Walter J. Sowden, Walter J. Sowden

Faculty Publications

Rates of suicide in the US Army continue to rise, and by some accounts exceed the general population. This increase has renewed efforts to identify protective factors that may inform novel suicide prevention strategies. Previous research has demonstrated that a sense of purpose in life and perceived cohesion with military peers are related to a reduction in the severity of suicidal ideation (SI). Additionally, research in military samples supports decreased SI in Soldiers who endorse that their leaders convey a sense of purpose and meaning in their shared mission. However, no work has investigated whether these leadership styles relate to …

Development Of A Memories Vocabulary (Memvoc) For Food Products Using Coffee As Model, Adan Cabal-Prieto, Gabriela Teodoro-Bernabé, Cecilia Coria-Rincón, Lucia Sánchez-Arellano, Lorena Guadalupe Ramón-Canul, Jesús Rodríguez-Miranda, Witoon Prinyawiwatkul, José Manuel Juárez-Barrientos, José Andrés Herrera-Corredor, Emmanuel De Jesús Ramírez-Rivera

Multiple references in sensory science indicate that foods evoke memories during consumption, however, research regarding those memories is still limited. The objective of this study was to develop a vocabulary and implement it in a memories vocabulary related to food as a complement for the evaluation of sensory attributes and emotions, using coffee as a model. The memories vocabulary was generated with a series of successive studies that involved assigning positive and negative memories to different food groups and applying mathematical algorithms (WordCountAna and Factorial Approach) and contrasting memories with the scientific literature. Subsequently, the vocabulary was used to determine …

Molecular Data From The Holotype Of The Enigmatic Bornean Black Shrew, Suncus Ater Medway, 1965 (Soricidae, Crocidurinae), Place It In The Genus Palawanosorex, Jonathan A. Nations, Thomas C. Giarla, Muhd Amsyari Morni, Julius William Dee, Mark T. Swanson, Anna E. Hiller, Faisal Ali Anwarali Khan, Jacob A. Esselstyn

Faculty Publications

Although Borneo has received more attention from biologists than most other islands in the Malay Ar-chipelago, many questions regarding the systematic relationships of Bornean mammals remain. Using next-generation sequencing technology, we obtained mitochondrial DNA sequences from the holotype of Suncus ater, the only known specimen of this shrew. Several shrews collected recently in Sarawak are closely aligned, both morphologically and mitochondrially, with the holotype of S. ater. Phylogenetic analyses of mitochondrial sequences indicate that the S. ater holotype and new Sarawak specimens do not belong to the genus Suncus, but instead are most closely related to Palawanosorex muscorum. Until now …

No Guts About It: Captivity, But Not Neophobia Phenotype, Influences The Cloacal Microbiome Of House Sparrows (Passer Domesticus), T. R. Kelly, A. E. Vinson, G. M. King, C. R. Lattin

Faculty Publications

Behavioral traits such as anxiety and depression have been linked to diversity of the gut microbiome in humans, domesticated animals, and lab-bred model species, but the extent to which this link exists in wild animals, and thus its eco- logical relevance, is poorly understood. We examined the relationship between a behavioral trait (neophobia) and the cloacal microbiome in wild house sparrows ( Passer domesticus, n = 22) to determine whether gut microbial diversity is related to per- sonality in a wild animal. We swabbed the cloaca immediately upon capture, assessed neophobia phenotypes in the lab, and then swabbed the cloaca …
