Acute Aortic Dissection Masquerading As Testicular Torsion: A Case Report, Bruce M. Lo, Megyn K. Christensen, Coral E. Byrns, Benjamin Chidester

Department of Emergency Medicine Faculty Publications

Introduction: Aortic dissection is a rare but life-threatening condition with a high mortality rate if diagnosis is delayed. Aortic dissection classically presents with sudden-onset, sharp pain in the chest or back. However, atypical presentations can also occur, which could lead to a delay in diagnosis.

Case Report: A patient initially presented to the emergency department (ED) with left testicular pain ongoing for several hours. On examination, he had tenderness in the left lower quadrant abdomen and left testicle. A testicular ultrasound revealed decreased blood flow to the left testicle, raising concern for testicular torsion. The patient was taken to the …

Does The Use Of Protective Behavioral Strategies Moderate The Relationship Between Perceived Peer Cannabis Use And Personal Use?, Mia Forsythe, Erica E. Mcdonald, Melissa N. Manning, Audrey L. Bell, Alicia Moulder, Cathy Lau-Barraco

Knowledge and Creativity Expo

The perception that close friends frequently use substances (i.e., descriptive norms) has been shown to increase personal use frequency and subsequent negative consequences. Within alcohol literature, protective behavioral strategies (PBS), actions aimed at reducing negative consequences of substance use (e.g., avoiding use before work), have been shown to moderate the effect of this relationship. However, this relationship in cannabis use remains unexplored. Thus, the current study examines PBS use as a moderator between descriptive norms and cannabis use frequency. We hypothesize that a positive association between descriptive norms and cannabis frequency will be weakened by greater PBS use. Undergraduate past-month …

Under Pressure: Associations Between Discrimination, Expressive Suppression, And Coping Drinking Motives Among Sexual Minority Women, Erica E. Mcdonald, Mia Forsythe, Audrey L. Bell, Melissa N. Manning, Alicia Moulder, Cathy Lau-Barraco

Knowledge and Creativity Expo

Within Minority Stress Theory, heterosexist discrimination has been linked to drinking to cope (DTC) motives, or drinking as a way to manage negative emotions. DTC motives are associated with heightened negative consequences from drinking. Prior research has found that high levels of expressive suppression (i.e., inhibition of ongoing emotion-expressive behavior) confer risk for coping motivated drinking. Given sexual minority women’s (SMW) elevated risk for DTC motives, examining expressive suppression and discrimination as correlates may address an important gap in literature. Thus, the current study examined expressive suppression as a factor impacting the relationship between external discrimination and coping motives among …

A Macrocognitive Design Taxonomy For Simulation-Based Training Systems: Bridging Cognitive Theory And Human-Computer Interaction, Jessica M. Johnson

Virginia Digital Maritime Center (VDMC) Faculty Publications

Simulation-based training systems are increasingly deployed to prepare learners for complex, safety-critical, and dynamic work environments. While advances in computing have enabled immersive and data-rich simulations, many systems remain optimized for procedural accuracy and surface-level task performance rather than the macrocognitive processes that underpin adaptive expertise. Macrocognition encompasses higher-order cognitive processes that are essential for performance transfer beyond controlled training conditions. When these processes are insufficiently supported, training systems risk fostering brittle strategies and negative training effects. This paper introduces a macrocognitive design taxonomy for simulation-based training systems derived from a large-scale meta-analysis examining the transfer of macrocognitive skills from …

Maintaining Trust In Uncertain Times: Funding Pauses And The Ethical Cost To Community-Engaged Research, Brynn E. Sheehan

Department Psychiatry & Behavioral Science Faculty Publications

Federal funding pauses, once considered rare, are increasingly disrupting the stability and continuity of community‐engaged research. Even projects with active, awarded grants are experiencing the strain of funding uncertainty, raising substantive concerns among research teams and community partners. These disruptions extend beyond operational delays; they jeopardize the continuity of relationships developed through sustained, collaborative engagement. In the absence of clear information about a project's future, uncertainty undermines trust and challenges the ethical principles that guide human subjects research, particularly beneficence and justice. This paper draws on direct experience and insights from the broader field to examine the practical and ethical …

Improving Pediatric Emergency Department Lethal Means Safety Documentation Rates For Adolescents With Mental Health Concerns, Cassandra L. Stegall, Ana-Maria Mcgill, John Fanton, Paul C. Mullan

Department Psychiatry & Behavioral Science Faculty Publications

Introduction:

Lethal means safety counseling (LMSC) is recommended for children presenting to the emergency department (ED) for a mental health (MH) evaluation. Currently, no gold-standard guidelines exist for documenting LMSC in the ED.

Methods:

This quality improvement project was conducted in the ED of a tertiary children's hospital. Baseline data were analyzed for access to any LMSC documentation (ALD) for "firearms/guns," "sharps," or "medication," and for complete LMSC documentation (CLD) if access to all 3 types was documented. The first intervention period added open-ended screening questions about access to lethal means to the MH-licensed clinical social worker note template. Intervention …

Health Behavior, Policy & Management Faculty Publications

Amid the racial unrest stemming from the summer of 2020, in the United States, many institutions had difficult conversations about race and the impact of racism with employees, students, and patients. In January 2021 and February 2021, we recruited undergraduate students for the Peer Education Program (PEP), a voluntary program conducted at a large academic medical center, and encouraged students to have a safe space to discuss controversial topics in healthcare. From April 2021 to July 2021 four interdisciplinary healthcare students met once a month for 1 hr to discuss privilege, race/racism, leadership, and advocacy and their influence on health …

China's Economic Retaliation Against Norway After Liu Xiaobo's 2010 Nobel Peace Prize, Ian Murphy, Shaomin Li

Management Faculty Publications

This case study analyzes China's geoeconomic retaliation against Norway after the 2010 Nobel Peace Prize was awarded to Liu Xiaobo. China employed non-tariff barriers, diplomatic freezes, and restricted exchanges, severely impacting sectors like salmon exports. This occurred despite the Nobel Committee's independence from the Norwegian government. Although Norway's overall economic impact was mitigated by market adjustments, the six-year diplomatic freeze significantly influenced its human rights foreign policy. This case exemplifies China's strategic use of informal economic tools to punish and deter, showcasing the link between political sensitivities and economic leverage in international relations.

Can We Talk? A Correspondence Study To Examine Responsiveness Of Physical Educators To Requests For A Phone Call From Parents Of Children With Disabilities, Sean Healy, Justin A. Haegele, Steven K. Holland

Human Movement Studies & Special Education Faculty Publications

The Individuals with Disabilities Education Improvement Act (2004) mandates that parental input be considered when making educational decisions for children with disabilities, including in physical education. However, parents of children with disabilities often report suboptimal communication experiences with physical educators. The purpose of the current study was to examine if the initiation of a parent–physical educator relationship is influenced by whether students have a disability or not. An online message correspondence study methodology was used to detect potential disparities in the responsiveness of a sample of 320 physical educators to electronic message requests for a phone call to discuss physical …

A random-effects model was utilised to estimate the potentially heterogeneously distributed effect sizes with a 95 % …

Professional Standards For School-Based Behavior Analysts (2nd Edition), Selena J. Layden, Emily Muise, Karen L. Berlin, Samantha Gregory, Daniel Irwin, Kaylan Long, Daria K. Lorio-Barsten, Jennifer L. O’Berry, Hannah Riddle

Human Movement Studies & Special Education Faculty Publications

Public educational settings are unique and complex environments that require specific knowledge and skills for the professionals that work in these environments. School-based behavior analysts can be a great asset to public schools. However, these professionals must be able to firmly understand and perform the responsibilities of a behavior analyst in collaboration with educators and service providers in a public school setting. The presence of behavior analysts in public schools is still relatively new, when compared with other specialized services. Therefore, behavior analysts, teachers, administrators, and others should focus on collaboration to promote the success for all stakeholders with an …

Considerations For School Leadership In Leveraging School-Based Behavior Analysis For Systemic Improvement In Public Education, Virginia Public Schools Behavior Analyst Network, Kira Austin, Elizabeth Boynton, Amanda K. Cash, Meredith Eads, Daniel Irwin, Selena Layden, Daria K. Lorio-Barsten, Emily Muise, Nadine Pittman, Felicia Shelton, Indya Watts-Graves

Human Movement Studies & Special Education Faculty Publications

Public schools face significant challenges, including rising student behavioral needs, chronic absenteeism, and high rates of teacher burnout. These issues are interconnected with and inextricably linked to a need for effective, evidence-based behavioral supports. Educators frequently enter the field lacking the necessary skills and training to manage complex student behavior, often resulting in a reliance on punitive practices that exacerbate problems.

This paper proposes that the expertise of school-based behavior analysts (SBBAs), who are Board Certified Behavior Analysts® (BCBAs®) specializing in education, offers a powerful, underutilized solution. SBBAs are trained in applied behavior analysis (ABA), a data-driven science focused on …

Felt Ambivalence Weakens The Attitude-Intention Pathway For Regular Leisure-Time Physical Activity In Chinese Adolescents: A Three-Wavee Prospective Study, Yaogang Han, Yubing Wang, Pan Li, Guohua Zheng

Human Movement Studies & Special Education Faculty Publications

Background: Favorable attitudes toward regular leisure-time physical activity may not always translate into intention if adolescents feel ambivalent about the behavior. This study tested whether felt ambivalence weakens the prospective attitude–intention association and the indirect effect of attitude on later behavior through intention. Methods: Chinese adolescents (N = 1714; Grades 7–12; mean age = 15.0 years) completed a three-wave survey at approximately two-week intervals. Wave 1 assessed attitudes toward regular leisure-time moderate-to-vigorous physical activity, felt ambivalence, and physical activity habit; Wave 2 assessed intention; and Wave 3 assessed leisure-time physical activity. Moderated mediation was tested in a structural equation model …

From Intention To Enactment: Action Planning And Habit Automaticity Distinguish Successful From Unsuccessful Intenders To Engage In Regular Leisure-Time Moderate-To-Vigorous Physical Activity, Yaogang Han, Yubing Wang, Pan Li, Binn Zhang

Human Movement Studies & Special Education Faculty Publications

University students often intend to exercise regularly but fail to translate intention into action. The present study tested which post-intentional processes distinguish successful from unsuccessful intenders in self-reported regular leisure-time moderate-to-vigorous physical activity (MVPA) enactment. Chinese undergraduates from 10 universities completed a three-wave survey administered at roughly two-week intervals. Habit automaticity was assessed at Wave 1, intention together with action planning and coping planning at Wave 2, and self-reported regular-exercise status at Wave 3. Because the dependent variable was assessed using a single stage-based self-report item, the findings should be interpreted as explaining self-reported regular-exercise status rather than objectively measured …

The Relationship Between Physical Activity, Sleep, And Hallucinations In Adults With Charles Bonnet Syndrome, Jarrod Hollis, Rohit Narayan, Eldre W. Beukes, Rosie Lindsay, Aliyah Bharwani, Umair Mughal, Ikra Yaqoob, Justin A. Haegele, Scott Muriden, Peter M. Allen

Human Movement Studies & Special Education Faculty Publications

Physical activity levels, hallucination experiences, sleep quality, and perceived stress were assessed using a survey administered to 57 adults with a confirmed diagnosis of Charles Bonnet Syndrome (CBS). Physical activity demonstrated a significant negative correlation with hallucination severity (r = –0.335, p = 0.011, two-tailed). A significant negative correlation was also observed between physical activity and perceived stress (r = –0.497, p < 0.001, two-tailed). In contrast, no significant association was identified between hallucination frequency and sleep disruption or insomnia. These findings suggest that engaging in appropriate levels of physical activity may help reduce the severity of hallucinations and mitigate stress among individuals with CBS. The observation that higher levels of physical activity are associated with reduced hallucination burden may help the development of evidence-based management strategies for CBS. Additionally, the finding that physical activity was significantly related to hallucination severity, whereas sleep disruption was not, merits deeper exploration in future research.

When Price Varies Across Otas: How Room Rate Disparity Shapes Switching Behavior And Brand Trust, Ling Ling, Chich-Chien Chen, Zvi Schwartz

Human Movement Studies & Special Education Faculty Publications

This study investigates how room rate disparity across Online Travel Agencies (OTAs) influences consumers’ switching behavior and perceptions of hotel brand integrity. Employing a scenario-based experimental design with a sample of 430 Chinese consumers, we explored price differences interact with loyalty status, price trajectory information, and brand consistency. Our findings reveal a complex non-linear inverse sigmoid relationship between rate disparity and channel switching. Contrary to expectations, loyalty membership did not reduce switching intent or increase discount thresholds. Moreover, rate disparity triggered brand integrity concerns, with brand doubt consistently exceeding switching intent. While price trajectory information did not change switching likelihood, …

Reward Deficits In Co-Occurring Social Anxiety And Depression: The Roles Of Anhedonia, Boredom, Loneliness, And Covid-19 Social Restriction, Nathan M. Hager, Alicia L. Milam, Hannah C. Hamrick, Benjamin Swanson, Matt R. Judah

Psychology Faculty Publications

Prior research points toward reward deficits as crucial to the link between social anxiety disorder and major depressive disorder. However, studies have not explored specific types of reward deficits or how social-environmental factors may impact them. The current study examined whether the indirect effects of three reward deficits (anhedonia, boredom, and loneliness) accounted for the connection between social anxiety and depression. Questionnaires were collected in a sample of college students (N = 523) during the first year of the COVID-19 pandemic, allowing examination of environmental stressors (i.e., remote learning and current friend network size) on reward deficits. Indirect effect models …

The (Non) Numeric Truths Behind College And Career Aspirations: A Quantcrit Analysis Of The Precarious Pathways For Secondary Students Of Color, Norma A. Marrun, Danielle Mireles, Jori S. Beck, Christine Clark

Teaching & Learning Faculty Publications

This article explored the college and career choices of 963 students across six urban secondary schools in a large public school district in the Southwestern United States. A Quantitative Critical Race Theory, or QuantCrit, analysis was applied to expose the false narrative of number neutrality and the systemic racism that belies it. Findings demonstrate how the myth of meritocracy through education (as ‘the great equalizer’) is perpetuated when educators hold onto racist and ableist beliefs about who can pursue college, and ignore the structural disadvantages underlying the college and career aspirations of students of Color juxtaposed with the reality of …

Design thinking, a problem-solving approach, has been offered as a strategy to address the challenges of growing and complex teaching expectations. In this narrative, I describe an adapted model of design thinking that was implemented in a secondary STEM methods course for teacher candidates in a graduate program. A description of the key activities, including the fundamental role of empathizing, is shared. Design thinking, when implemented by teachers and teacher candidates, allows the teacher to design and improve a lesson or unit based on student feedback and engagement. This is especially important in today's rapidly evolving educational landscape, where educators …

Secondary Teachers' Experiences In International Professional Development For Convergence Research In Stem And Tradition, Rachel Sparks White, Kristie S. Gutierrez, James K. Ferri

Teaching & Learning Faculty Publications

Convergence education promotes learning experiences that integrate science, technology, engineering, and mathematics (STEM) to address complex real-world problems. However, secondary teachers often report limited access to professional development (PD) and curricular resources that support transdisciplinary instruction. This exploratory case study examines how four secondary teachers (three chemistry; one engineering) made sense of a transdisciplinary PD model, Convergence Research in STEM and Tradition (CReST), that leverages cultural heritage artifacts (Renaissance frescoes) as boundary objects to connect chemistry, engineering, world history, and technology. Teachers participated in a four-day immersive PD experience in Firenze (Florence) and Pisa, Italy, that included site-based learning, interaction …

Girls Stem Institute: Impacting Black Girls' Self-Efficacy And Interest In Stem Careers, Crystal Morton, Demetrice Smith-Mutegi, Danka Maric, Vidushi Adlakha, Robin Jackson

Teaching & Learning Faculty Publications

Nationally and globally, STEM serves as a gatekeeper to the labor market and higher education opportunities. Many Black girls find themselves locked out of the gate. Historically and contemporarily, Black girls are seldom viewed as capable or worthy of educational investment and face unique and ongoing challenges in K-12 STEM learning spaces due to their gender and racial identities. Research suggests that informal STEM learning spaces can serve as a counter to Black girls’ experiences in K-12 schools and help enhance Black girls’ self-efficacy and STEM career interests. This study explores the impact of a four-week informal STEM program, employing …

But Who Are The Victims? Reassessing The 568 Higher Education Cartel, James V. Koch

Economics Faculty Publications

Thirty prestigious independent American institutions of higher education were at some time members of the 568 higher education group (often labeled a cartel). Seventeen of them were sued by the U.S. Government and representative students who alleged that their meetings and deliberations resulted in collusion that caused students to pay higher prices. Twelve of the seventeen institutions subsequently settled their cases and by 2024 collectively had paid $284 million to do so. However, an inspection of these institutions' pricing reveals that the median 568 Group institution lowered its average real net annual cost to its undergraduate students by 19.07% between …

Living In A Bubble: How Children And Adults Use Generics To Talk About Social Kinds In Unique Sociocultural Contexts, Ny Vasil, Alejandro Curiel, Tiffany Zhu, Anna Pederneschi, Katherine Ritchie

Philosophy Faculty Publications

Generics like "kids love sugar" convey generalizations. But what is their scope? Are they taken to be global, or can generics communicate regularities restricted to "sociocultural bubbles"? Two studies examined the developing capacity for contextual restriction of generics in 137 4-7-year-olds (63/70/4 female/male/other) and 222 adults (128/89/5 female/male/other). Participants evaluated generics attributing group properties prevalent globally vs. "within-bubbles," with contextual cues that speakers conveyed broad vs. contextually restricted regularities. Both children and adults appreciated that generics can communicate group characteristics occurring within narrow sociocultural contexts. Adults selectively endorsed global or local generics depending on context, but younger children allowed socially …
