Gamma-ray bursts (GRBs) are among the brightest and most energetic events in the Universe. The duration and hardness distribution of GRBs has two clusters(1), now understood to reflect (at least) two different progenitors(2). Short-hard GRBs (SGRBs; T-90 < 2 s) arise from compact binary mergers, and long-soft GRBs (LGRBs; T-90 > 2 s) have been attributed to the collapse of peculiar massive stars (collapsars)(3). The discovery of SN 1998bw/GRB 980425 (ref. (4)) marked the first association of an LGRB with a collapsar, and AT 2017gfo (ref. (5))/GRB 170817A/GW170817 (ref. (6)) marked the first association of an SGRB with a binary neutron star merger, which also produced a gravitational wave. Here, we present the discovery …

Caregiver Treatment Consumption In An Experimental Treatment Marketplace, Delaney J. Darragh

Faculty Publications

Behavioral economics is an approach to understanding consumer behavior by integrating behavioral science with economic principles. Behavioral economics incorporates traditional economic principles with operant learning approaches. There is limited research examining how individuals consume psychological and behavioral treatments. This is especially the case for treatments designed for children. The current study used data from a previously collected sample to explore gender differences in an experimental treatment marketplace (ETM). Experimental treatment marketplaces are generally used to evaluate choices between goods and services (e.g., types of behavior interventions). An ETM was developed to evaluate treatment consumption when levels of evidence differed between …

Preschool Mathematics Performance And Executive Function: Rural-Urban Comparisons Across Time, Jacob A. Esplin, Ann M. Berghout Austin, Belinda Blevins-Knabe, Brionne G. Neilson, Robert F. Corwyn

Faculty Publications

This longitudinal study examined the relationship between executive function (EF) and mathematics with rural and urban preschool children. A panel of direct and indirect EF measures were used to compare how well individual measures, as well as analytic approaches, predicted both numeracy and geometry skill. One hundred eighteen children, ages 39 to 68 months, were given EF and mathematics assessments twice, approximately six months apart, concurrent to their teachers completing an indirect assessment of EF for each child. Results suggest: (1) the child’s age determines if a panel of direct EF measures is a better predictor of numeracy and geometry …

Distinguishing Relational Turbulence, Marital Satisfaction, And Parenting Stress As Predictors Of Ineffective Arguing Among Parents Of Children With Autism, Kellie St Cyr Brisini, Denise Haunani Solomon

Faculty Publications

Relational turbulence theory suggests that relational turbulence causes pervasive patterns of dysfunctional communication in romantic relationships, such as an inability to resolve conflicts. Other research traditions link marital conflict to marital satisfaction and also exposure to stress. This study assesses the discriminant validity of relational turbulence by examining its association with reports of ineffective arguing, above and beyond the associations with marital satisfaction and parenting stress. The study tests the theoretical claims within the high stress context of parents raising children with autism spectrum disorder (ASD). Married, parents of children with ASD (N = 298) completed measures of parenting stress …

Going Feminine: Identifying How And When Female Candidates Emphasize Feminine And Masculine Traits On The Campaign Trail, Nichole M. Bauer, Martina Santia

Faculty Publications

Female candidates face a messaging challenge. There is a strong association between masculinity and political leadership. Stressing masculinity can result in a likability backlash for female candidates often seen as lacking feminine qualities, such as warmth. Preventing a likability backlash by highlighting feminine qualities can also harm female candidates. Current scholarship offers conflicting conclusions about how female candidates balance these gendered challenges. We fill this empirical and theoretical gap with a trait-balancing theory clarifying how and when female candidates use feminine and masculine traits to manage competing expectations. We use original data merging information on candidate advertising strategies across three …

Agronomic And Environmental Performance Of Biochar Amendment In Alluvial Soils Under Subtropical Sugarcane Production, Negar Tafti, Jim Wang, Lewis Gaston, Jong Hwan Park, Meng Wang, Scott Pensky

Faculty Publications

This study investigated the amendment of sugarcane bagasse biochar (SCBB) on soil fertility, crop yield, and nutrient loss in two different-textured soils under sugarcane (Saccharum spp.) production. Eleven megagrams per hectare of freshly incorporated biochar increased yield of plant cane by 22% in light-texture soil (LS) and 12% in heavy-textured soil (HS). Although the overall yield of the ratoon crop was lower, the biochar treatment produced 20 and 14% higher yields than the control at the LS and HS sites, respectively. Biochar increased soil carbon (Csoil) across LS and HS sites by 15% and decreased the soil C/N ratio by …

Eat Clean And Safe Food: A Food-Based Dietary Guideline For The Elderly In South Africa, Makenzie Miller, Wilna Oldewage-Theron, Carin Napier

Faculty Publications

As the population of elderly individuals in South Africa (SA) grows, there is a need to promote the continued health of these persons as they progress through the life cycle. Food Based Dietary Guidelines (FBDGs) for the SA elderly were developed to address this need. These thirteen guidelines for the elderly collectively offer a basis of health practices that the elderly can follow to ensure that they are taking the right steps toward maintaining their health. While the guideline ‘Eat clean and safe food’ is not included in the current SA FBDGs, this recommendation is of particular importance to the …

Food And Beverages Promoting Elderly Health: Six Food-Based Dietary Guidelines To Plan Good Mixed Meals For Elderly South Africans, Sanjoy Saha, Upasana Mukherjee, Makenzie Miller, Li Ling Peng, Carin Napier, Heleen Grobbelaar, Wilna Oldewage-Theron

Faculty Publications

Studies have shown that the elderly are at a higher risk of developing malnutrition due to physiological and pathological changes. Several studies have confirmed that older South Africans have insufficient dietary diversity, resulting in nutritional deficiencies. Furthermore, poor and uninformed dietary choices are associated with the development of several diseases and increased mortality. Following the Elderly Food Based Dietary Guidelines (EFBDGs) related to promoting elderly health could ensure that the elderly have an adequate intake of nutritious foods. This paper provides an overview of six FBDGs relating to promoting health and is based on the South African Food Based Dietary …

Solopreneur Digital Ecosystems: Genesis, Lineage And Preliminary Categorization, Gabriele Piccoli, Biagio Palese, Joaquin Rodriguez

Faculty Publications

This paper traces the genesis and lineage of solopreneur digital ecosystems. These ecosystems, fostered by a digital environment that is infrastructural, combinatorial and servitized, are enabling the rise to prominence of the solopreneur. We theorize solopreneur digital ecosystems as the latest incarnation of systems beyond firm control, with digital platforms and digital marketplaces as their principal enablers. In an effort to compare them from the perspective of the solopreneur, we categorize solopreneur digital ecosystems on three dimensions: algorithmic control, commoditization, and lock-in. Our work contributes a framework that solopreneurs can use to identify ecosystems in which they can optimally invest …

Systena frontalis (F.) (Coleoptera: Chrysomelidae) is an important pest in ornamental plant nurseries in the United States. Information on current pest status and management practices employed by nurseries, garden centers, and landscape care operations are crucial to developing an effective research and extension program for ornamental crops. An online survey was developed and administered by the research team in 2020 to gather data on pest status and current pest management practices. The questionnaire included three focus areas: 1) participant (location, industry type, or operating area); 2) pest status indicators (incidence, affected crops, and estimated loss); and 3) common pest management …

What’S In A Name? Strict Scrutiny And The Right To A Public Trial, Stephen Smith

Faculty Publications

The right to a public trial has only rarely been addressed by the Supreme Court, but in Waller v. Georgia, the Court set forth a test for determining when it is appropriate to close a courtroom to the public, despite the general public trial command. The language of the Waller test suggests great rigor. This essay proposes a reconsideration of the test for courtroom closures, rethinking whether traditional strict scrutiny thinking is appropriate in this constitutional and practical context. That said, this essay does not argue with Waller’s broad outlines. Courts making closure decisions should consider reasons and …

Restraining The Unsupervised Fiduciary, Thomas Simmons, Andrew Knutson

Faculty Publications

In 2020, Governor Kristi Noem signed South Dakota's slightly tweaked version of the Uniform Power of Attorney Act (UPOAA) into law. That uniform act-now enacted in a total of twenty-eight states since approved by the Uniform Law Commissioners in 2006, represents a significant advancement in clarifying and regulating the use of powers of attorney. Given the widespread use of powers of attorney and their great potential for abuse and misuse, a comprehensive set of rules-both default and mandatory-is warranted. This article summarizes the UPOAA as well as the history of uniform acts which preceded it. The arrangement and structure of …

Increasing Workplace Diversity: Evidence From A Recruiting Experiment At A Fortune 500 Company, Jeffrey A. Flory, Andreas Leibbrandt, Christina Rott, Olga B. Stoddard

Faculty Publications

While many firms have set ambitious goals to increase diversity in their ranks, there is a dearth of empirical evidence on effective ways to reach them. We use a natural field experiment to test several hypotheses on effective means to attract minority candidates for top professional careers. By randomly varying the content in recruiting materials of a major financial services corporation with more than 10,000 employees, we find that signaling explicit interest in employee diversity more than doubles the interest in openings among racial minority candidates, as well as the likelihood that they apply and are selected. Impacts on gender …

The Effects Of Metacognitive Listening Strategy Instruction On Esl Learners’ Listening Motivation, Grant Eckstein, Corbin Kalanikiakahi Rivera, Benjamin L. Mcmurry, David Eddington

Faculty Publications

Prior studies examining the effects of listening strategy instruction on motivation have shown a positive correlation between the two. However, the participants of these studies all shared a first language (L1) and were not enrolled in an intensive English program (IEP). This study aims to investigate the correlation between listening strategy instruction and listening motivation in an IEP classroom for students from different L1s. Listening motivation was recorded utilizing the English Listening Comprehension Motivation Scale (ELCMS), and strategy use was tracked with the Metacognitive Awareness Listening Questionnaire (MALQ). Pre- and post-test scores of 56 participants (control group, n=30; experiment group, …

The Poor And The Needy In The Book Of Isaiah, Dana M. Pike

Faculty Publications

When we read Jesus’s pronouncement in 3 Nephi that “great are the words of Isaiah” (3 Nephi 23:1), prophecies about the Messiah and the scattering and gathering of Israel are what may quickly come to mind. However, the book of Isaiah also contains important passages addressing the treatment of the poor and needy. These passages, which particularly focus on one of the many social ills in ancient Israelite society, range from condemning the unrighteous treatment of the poor to promising how the Lord will (eventually) deliver them.1

Repeated Word Production Is Inconsistent In Both Aphasia And Apraxia Of Speech, Tyson G. Harmon, Katarina L. Haley, Kevin T. Cunningham, Adam Jacks, Jessica D. Richardson, Peter E. Turkeltaub

Faculty Publications

Purpose: There is persistent uncertainty about whether sound error consistency is a valid criterion for differentiating between apraxia of speech (AOS) and aphasia with phonemic paraphasia. The purpose of this study was to determine whether speakers with a profile of aphasia and AOS differ in error consistency from speakers with aphasia who do not have AOS. By accounting for differences in overall severity and using a sample size well over three times that of the largest study on the topic to date, our ambition was to resolve the existing controversy.

Method: We analyzed speech samples from 171 speakers …

Spoken Discourse Assessment And Analysis In Aphasia: An International Survey Of Current Practices, Tyson G. Harmon, Brielle C. Stark, Manaswita Dutta, Laura L. Murray, Davida Fromm, Lucy Bryant

Faculty Publications

Purpose

Spoken discourse analysis is commonly employed in the assessment and treatment of people living with aphasia, yet there is no standardization in assessment, analysis, or reporting procedures, thereby precluding comparison/meta-analyses of data and hindering replication of findings. An important first step is to identify current practices in collecting and analyzing spoken discourse in aphasia. Thus, this study surveyed current practices, with the goal of working toward standardizing spoken discourse assessment first in research settings with subsequent implementation into clinical settings.

Method

A mixed-methods (quantitative and qualitative) survey was publicized to researchers and clinicians around the globe who have collected …

Kinematic And Acoustic Changes To Vowels And Diphthongs In Bite Block Speech, Christopher Dromey, Michelle Richins, Tanner Low

Mindfulness, Self-Inquiry, And Artmaking, Mark Graham, Rebecca Lewis

Faculty Publications

This article describes a qualitative study of pre-service art education students that was designed to explore relationships between mindfulness, self-inquiry, and artistic practices. The researchers, who are art educators, were curious about how mindfulness practices might connect, overlap or influence the personal artistic practice of the participants. Although mindfulness is often used as an intervention to counter the stresses of school and teaching, mindfulness can also be thought of as a counter cultural phenomenon that explores possibilities of a critical pedagogy. While mindfulness and self-care practices can have important positive benefits and may lead to deeper personal understanding, these practices …

Many Americans fail to get life-saving vaccines each year, and the availability of a vaccine for COVID-19 makes the challenge of encouraging vaccination more urgent than ever. We present a large field experiment (N = 47,306) testing 19 nudges delivered to patients via text message and designed to boost adoption of the influenza vaccine. Our findings suggest that text messages sent prior to a primary care visit can boost vaccination rates by an average of 5%. Overall, interventions performed better when they were 1) framed as reminders to get flu shots that were already reserved for the patient and 2) …

An Empirical Analysis Of Video Games And Social Media On Learning In An Information Systems University Class, Heber C. Brau, James C. Brau, James Gaskin

Faculty Publications

Prior research by Brau, et al. (2016, 2017) identifies factors that correlate with university student course grades. We employ the same research structure as the Brau, et al. papers with the innovation of adding dozens of questions that deal with video game and social media usage. Extant research argues that time spent on video gaming and using social media can: 1) hurt student grades, 2) help student grades, or 3) have no impact on student grades. We test the video game and social media impact hypotheses using a survey of over 500 college students in an Introduction to Information Systems …

Soft Information And The Underpricing Of Reit Seasoned Equity Offerings, James C. Brau, J. Troy Carpenter, James E. Cicon, Shelly Howton

Faculty Publications

Using a sample of 1,429 seasoned equity offerings (SEOs) by real estate investment trusts (REITs), we use content analysis to test whether the soft information in a company’s offering prospectus influences SEO underpricing. After controlling for relevant variables, we find that companies that use more positive (negative) words in their filings are negatively (positively) related to SEO underpricing. We posit that in REIT SEOs more positive and fewer negative words decrease investor pricing uncertainty (fear) of the offer and as a result experience less underpricing.
