Between Black Mothers And Daughters: A Critical Intergenerational Duoethnography On The Silence Of Health Disparities And Hope Of Loud Healing, Asha S. Winfield, Hope Hickerson, Deshara C. Doub, Ann R. Winfield, Brigitte Mcphatter

Faculty Publications

Introduction: Black American women's health outcomes have been altered by a number of factors. Those factors include social determinants of health, lack of culturally competent healthcare providers, and generations of medical racism leading to prolonged pain, delayed care, and sometimes, untimely deaths. Methods: This original research article centers Southern Black women's lived experiences through family storytelling. We explored generations of health narratives in regard to age, region, and at times, their own acts of silence. Building from theorizing on loud healing, two Black daughters turned the mic on for their mothers by engaging in a critical intergenerational double duoethnography to …

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.

“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 …

Pattern-Based Target Selection For Treatment Of Irregular Past Tense: A Single-Case Experimental Design For Children With Developmental Language Disorder, Kirsten M. Russell, Amy Wilder, Julie L. Wambaugh

Faculty Publications

Purpose: Many children with developmental language disorder (DLD) demonstrate
difficulty inflecting irregular past tense verbs. We evaluated using phonological-
based patterns (i.e., schemas) to select targets for treatment of irregular verb inflection for children with DLD. We hypothesized this approach would result in acquisition of treated verbs, generalization to untreated verbs within the same phonological schema, and increased use of correct irregular verbs in naturalistic contexts. Method: Treatment was provided to three 7-year-old participants with DLD in the context of multiple baseline designs across behaviors and participants. Phonological schemas included vowel change, final alveolar, and dual change irregular verbs. Treatment …

Evaluation Of A Complexity-Based Morphosyntactic Treatment For Children With Language Disorders Of Mixed Etiologies, Kirsten M. Russell

Faculty Publications

Language disorder is characterized by difficulty with the comprehension and production of different aspects of language. School-aged children with developmental language disorder (DLD) and school-aged children with Down syndrome (DS) demonstrate similar deficits in the area of morphosyntax, which often creates barriers during social interactions and for academic learning. Although affected children may receive intervention, progress can be slow. Selecting appropriate treatment targets is critical for effective intervention. Traditional approaches for selecting treatment targets are based on developmental readiness (i.e., developmental) or functional need (i.e., remedial). However, intervention utilizing targets selected by these methods produce only modest results, despite a …

Similar Overall Expression, But Different Profiles, Of Autistic Traits, Sensory Processing, And Mental Health Between Young Adult Males And Females, Garrett Cardon

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). No other study, intervention, or participant

Perceptual Ratings Of Pronunciation For L2 Learners Of English As A Function Of Task Type, Word Position, And Listener Expertise, Shawn L. Nissen, Rachel Kemmey, K. James Hartshorn

Faculty Publications

Abstract Second language (L2) learners of English must learn to pro-duce English phonemes, words, and sentences. These L2learners make many errors when learning English; they may change the place or manner of articulation, insert vowels, or delete consonants. Obstruent sounds, such as fricatives, affricates, and stops, can be especially difficult for L2 learners. This study analyzed native English speakers’ perception of the quality of obstruents produced by native Mandarin Chinese and Korean speakers. Target words containing obstruents had been produced in three different tasks: in a carrier phrase, in a paragraph, and in a spontaneous speechsample. Obstruents were produced in …

Improving Psychological Well-Being Of Young Adults By Conducting Family History Research At A Religious University, Barry M. Lunt, Kelly R. Summers, David A. Wood

Faculty Publications

Prior research suggests that knowledge of one’s family is correlated with, but does not produce, psychological well-being. We test this conjecture, by examining whether participating in family history research (i.e., genealogical research) is associated with psychological well-being above and beyond the effects of knowledge of one’s family, documented in prior research. To test this, we examine whether students enrolled in a university level family history course, improve in family identification, self-esteem, anxiety, resilience, and locus of control more than a control sample. For students enrolled in the family history course, we find an increase in family identification, which in turn …

Data Visualization In 10-K Filings, Theodore E. Christensen, Karson E. Fronk, Joshua A. Lee, Karen K. Nelson

Faculty Publications

The Securities and Exchange Commission encourages the presentation of information or data in graphical form to improve users’ ability to understand financial disclosures. We find a dramatic increase in the disclosure of both qualitative and quantitative infographics in 10-K filings over time and substantial cross-sectional variation in firms’ choices regarding image types, data content, and the placement of infographics within 10-Ks. We provide evidence on factors associated with firms’ use of infographics and explore the persistence with which they are disclosed over time. Finally, we investigate the relation between the use of infographics and uncertainty in capital markets.

The Right To A Public Trial, Conditional Courtroom Entry And Tiers Of Constitutional Scrutiny, Stephen Smith

Faculty Publications

The constitutional test the SupremeCourt has prescribed to review courtroom closures for compliance with the Sixth Amendment’s right to a public trial is in the nature ofstrictscrutiny. The Courtrequires an “overriding interest” to justify the closure, and a narrow, minimally restrictive scope to the closure. Many lower courts have imposed a less demanding test for “partial” closures, which admit to the courtroom some, but not all, of the public. These courts require a less demanding justification before closing the courtroom to certain individuals—the justification need be only “substantial,” ratherthan “overriding.” Thisstandard is in the nature of intermediate scrutiny, as applied …

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.

Alcohol Misuse And Gun Violence: An Evidence-Based Approach For State Policy, Silvia Villarreal, Amy Bornhorst, Richard Bonnie, Kami Chavis, Ari Davis, Shannon Frattaroli, Kelly Roskam, Jeffrey Swanson, Joshua Horwitz

Planetary protection is a set of measures agreed upon at an international level to ensure the protection of scientific investigation during space exploration. As space becomes more accessible with traditional and new actors launching complex and innovative projects that involve robotics (including sample return) and human exploration, we have the responsibility to protect the pristine environments that we explore and our own biosphere. In this sense, the Committee on Space Research (COSPAR) provides the international standard for planetary protection as well as a forum for international consultation. COSPAR has formulated a Planetary Protection Policy with associated requirements for responsible space …

Dataset For Effects Of Single-Session Practice Structure On Motor Skill Acquisition And Alpha And Beta Eeg Oscillations, Audrey Porter, Ronald V. Croce, Wayne Smith

Faculty Publications

Although it is known that practicing a motor skill updates the associated internal model, it is still unclear as to how cortical oscillations linked with the motor skill change under differing practice schedules. The current study investigated α- and β-power changes associated with motor skill acquisition. Firstly, we investigated the behavioral effects of practice on motor learning and retention during repetitive (RP) and variable (VP) practice schedules on an anticipation timing task. Secondly, we investigated changes in cortical α (10-13 HZ) and β (15-30 Hz) event-related synchronization and dyssynchronization (ERS/ERD) under RP and VP during early (EP) and late …

Interfacial Activity And Surface Pka Of Perfluoroalkyl Carboxylic Acids (Pfcas), Ruchi Patel, Luis E. Saab, Philip J. Brahana, Kalliat T. Valsaraj, Bhuvnesh Bharti

Faculty Publications

Perfluoroalkyl carboxylic acids (PFCAs) are widely used synthetic chemicals that are known for their exceptional stability and interfacial activity. Despite their industrial and environmental significance, discrepancies exist in the reported pKa values for PFCAs, often spanning three to four units. These disparities stem from an incomplete understanding of how pH influences the ionized state of PFCA molecules in the bulk solution and at the air-water interface. Using pH titration and surface tension measurements, we show that the pKa values of the PFCAs adsorbed at the air-water interface differ from the bulk. Below the equivalence point, the undissociated and dissociated forms …

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 …
