Effects Of Radiation Type On Charge Transport In Aged Polymers, Zachary J. Gibson, Jr Dennison, Virginie Griseri

Journal Articles

Spacecraft charging issues are often investigated with simulated space environments and evaluated on pass–fail criteria that may yield little or no information about materials’ properties. It is far more effective to understand and mitigate spacecraft charging issues through investigations of material properties. However, material properties are dynamic in the harsh environment of space. Approximations must be made to simulate the space environment in the laboratory. This article reports on the investigation of the approximation that energy deposition causes the same aging effects in materials irrespective of the type of radiation sources. Samples of polytetrafluoroethylene (PTFE) and polyether-etherketone (PEEK) were irradiated …

Bending Energy Schemes For Discrete-Spring-Network Structural Modelling Of Red Blood Cells, Osayomwanbor Ehi-Egharevba, Mingzhu Chen, Fergal Boyle

Articles

Red blood cells (RBCs) undergo large structural deformation, including bending, when passing through capillaries. They also exhibit a range of complex shapes such as stomatocytes, discocytes and echinocytes that form due to altered blood pH and salt levels, ingested drugs and adenosine triphosphate depletion. Discrete-spring-network structural models of RBCs employ different numerical treatments of the continuum bending energy. This affects bending accuracy and the prediction of accurate RBC shapes. This research compares three representations called bending energy scheme (BES) A, B and C to evaluate their accuracy in shape predictions. BES A, seen throughout the literature, is based on the …

Background

People living with HIV (PLWH) face a higher risk of cardiovascular disease (CVD), with significant sex differences in outcomes. However, it is unclear whether these differences are driven by distinct risk factor profiles or by a differential impact of shared risk factors. This study aimed to identify factors associated with CVD among PLWH and to specifically assess for effect modification by sex using a large, diverse nationwide database.

Methods

We utilized data from the All of Us Research Program (AoU). The primary outcome was a composite of coronary artery disease or stroke. We used multivariable logistic regression to identify …

What's My Age Again? The Curious Case Of Natalia Grace And The Constitutional Void In Re-Aging Law, Lauren Gay

Et Cetera

When a child’s legal age can be judicially reclassified without rigorous procedural safeguards, the foundations of American due process erode. This article explores the alarming constitutional vacuum exposed by the case of Natalia Grace, an adopted Ukrainian child whose age was legally reclassified from eight to twenty-two without procedural safeguards such as a hearing, legal counsel, or evidentiary testing. Unlike competency or parental rights proceedings, re-aging decisions lack uniform standards, judicial transparency, or appellate recourse. This article argues that re-aging implicates fundamental liberty interests and must be governed by heightened due process protections. Drawing on comparative models from guardianship and …

Student Alienation In Schools Goes Beyond Low Achievement, Sean J. Drake, Jeffrey Guhin

Center for Policy Research

When we think about students struggling in school, we often focus on grades, test scores, and graduation rates. But there's a deeper problem affecting students across all achievement levels: alienation. Students feel disconnected from school not because they're failing, but because they can't see themselves in the narrow story schools tell about success. This brief summarizes findings from a study drawing on over two years of ethnographic fieldwork in two different high schools in Los Angeles, California. The authors identify four types of alienation students experience: feeling like they don't belong, being in schools that can't support their goals, pursuing …

Bias-Based Bullying Among Middle Eastern & North African Students: Potential Protective Factors, Nadeen Alshakhshir, Barbara Mcmorris, Hana-May Eadeh

Biennial Convention (CONV)

Bullying victimization among school students is associated with negative psychosocial experiences such as anxiety, depression, and sometimes suicidality.^1,2 Middle Eastern and North African (MENA) students experience bias-based bullying in schools at high rates compared to other non-minority groups.^1,3 Although much research focuses on this phenomenon, few studies explore the possible protective factors that buffer the effects of bias-based bullying among this specific group of students, such as religious participation and certain developmental assets. Religious participation is associated with less depression and anxiety symptoms among Asian American students.⁴ Developmental assets of empowerment, social competence, and positive identity enable …

Introduction Patients who survive admission to intensive care unit (ICU) for critical illness are at high risk of developing muscle atrophy and weakness, commonly diagnosed as ICU-acquired weakness (ICUAW). The development of ICUAW is closely linked to long-term symptoms and impairments known as post-intensive care syndrome (PICS). Despite heightened recognition of impairments, there is limited research supporting effective interventions to improve muscle and physical outcomes after hospital discharge. Prior to developing and testing interventions for ICU survivors, it is imperative to understand the trajectory of muscle and physical function recovery following an ICU stay. The purpose of this study is …

Introduction Deaths related to drug overdose and suicide in the USA have increased 500% and 35%, respectively, over the last two decades. The human and economic costs to society associated with these - €- deaths of despair' are immense. Great efforts and substantial investments have been made in treatment and prevention, yet these efforts have not abated these increasing trajectories of deaths over time. The COVID-19 pandemic has exacerbated and highlighted these problems. Notably, some geographical areas (eg, Appalachia, farmland) and some communities (eg, low-income persons, - €- essential workers', minoritised populations) have been disproportionately affected. Risk factors have been …

Autism In Higher Education: A Systematic Review, Katie Webber

Honors Theses - Providence Campus

As students with autism spectrum disorder (ASD) are increasingly represented in higher education, these students need to have their needs met, and many institutions lack the resources to do so. This systematic review synthesizes research on the experiences of students with autism in college, focusing on barriers, support services, and institutional interventions. A comprehensive search of peer-reviewed studies published between 2012 and 2025 identified 17 relevant articles. Findings reveal that students often experience difficulties with social integration, executive functioning, sensory sensitivities, and mental health, all of which can affect academic performance and retention. Evidence suggests that individualized supports, mentoring, structured …

Agitation In Alzheimer’S Disease: From Assessment To Therapeutics, Antonio L Teixeira, Youngran Kim, Thiago M Cordeiro, Gabriel A De Erausquin, Natalia P Rocha

Faculty, Staff and Student Publications

Agitation is a neuropsychiatric syndrome characterized by excessive motor and/or verbal behaviors, with or without aggressive behaviors. The prevalence of agitation in Alzheimer’s disease varies from 5% to over 50%. Multiple factors have been implicated in its pathophysiology, including disease stage, comorbidity with other symptoms (e.g., psychosis, anxiety/depression), and psychosocial factors. Ruling out delirium and identifying environmental triggers are fundamental steps in the management of agitation in Alzheimer’s disease. For establishing an effective therapeutic plan, it is important to define duration, severity, and potential for harm. While non-pharmacological approaches are considered the first line of intervention, pharmacological agents …
