Turning Zwitterions Into Toughening Agents: Salt-Activated Microdomains In Poly(Vinyl Alcohol) Double-Network Hydrogels, Louis D. Zhang, Jintao Yang, Si Yu Zheng

University Research

Zwitterionic hydrogels, although highly biocompatible, are widely regarded as mechanically fragile, with typical tensile strengths below 0.1 MPa, which restricts their use in load-bearing applications. Here, we address this limitation by integrating a polyzwitterionic network with a poly(vinyl alcohol) (PVA) network through high-speed pregelation agitation that enhances chain entanglement and induces flow orientation. By exploiting the salt-driven conformational transition of zwitterionic chains, a controlled salting-out step generates uniformly dispersed nanoscale microdomains that act as reversible energy-dissipating units. At the same time, balanced hydrogen bonding between the two networks moderates PVA crystallinity, limiting embrittlement while preserving elasticity. The resulting double-network hydrogel …

The Relationship Between Police Encounters And Anxiety Levels Among Urban Black Males Aged 18–40, Wilbert Smith

Walden Dissertations and Doctoral Studies

This quantitative, cross-sectional, correlational study examined the relationship between police encounter characteristics and anxiety symptoms among urban Black males aged 18–40 in the United States. Although prior research has documented racial disparities in police contact and adverse mental health outcomes, limited empirical work has examined how multiple dimensions of police encounters jointly relate to anxiety within this population. Guided by Critical Race Theory, the study assessed whether the frequency, severity, and perceived fairness of police encounters were associated with self-reported anxiety symptoms. Data were collected from 138 self-identified urban Black males using a nonprobability, self-selected sampling approach. Participants completed an …

Pretreatment Risk Model For Radiation-Induced Lymphopenia Is Associated With Adjuvant Durvalumab Efficacy In Patients With Unresectable Stage Iii Nsclc, Peter S N Van Rossum, Pim J J Damen, Francesco Cortiula, Brian P Hobbs, Lorenzo De Marchi, Radhe Mohan, Max Peters, Famke L Schneiders, Dirk De Ruysscher, Robin Wijsman, Joost J C Verhoeff, Ting Xu, Zhongxing Liao, Steven H Lin

Faculty, Staff and Student Publications

Introduction: Severe radiation-induced lymphopenia (RIL) during concurrent chemoradiotherapy (CCRT) for NSCLC has been associated with poorer outcomes and reduced immunotherapy efficacy. Because RIL often develops late during CCRT, identifying patients at risk before treatment may be clinically relevant. This study aimed to develop and validate a nomogram based on pretreatment predictors for severe RIL, and secondarily to explore associations between predicted RIL risk and adjuvant durvalumab-associated survival.

Methods: A retrospective development cohort of consecutive patients with NSCLC treated with CCRT (2010-2019) was established, along with an independent external validation cohort from other institutions. A multivariable logistic regression model was developed …

Machine Learning For Elderly Behavior And Risk Incident Modeling, Muhammad Tanveer Jan

Electronic Theses and Dissertations 2020 - Present

The rapid expansion of the aging population presents critical challenges to healthcare systems, particularly in maintaining independent living, ensuring mobility safety, and optimizing emergency interventions. Traditional monitoring solutions are often fragmented, reactive, and hindered by the scarcity of data regarding rare high-risk events. This dissertation proposes a comprehensive, multi-modal machine learning framework designed to model elderly behavior and predict risk incidents across three critical environments: the home, the vehicle, and the clinical setting.

To address the fundamental challenge of class imbalance in medical and behavioral datasets—where risk events are statistically rare—this research first introduces a dual-phase data augmentation strategy. By …

Making Sense Of And Responding To The Good And Bad Within Psychology: Common Grace And Antithesis As Tools For Psychology, Tyler Greenway, Cory B. Wilson

University Faculty Publications and Creative Works

As psychologists and students of psychology make sense of and respond to the good and bad within human behavior and its study, theological tools benefit their discernment. This paper presents two Neocalvinist theological concepts — common grace and antithesis — as tools for psychologists. These concepts help psychologists recognize God’s common gifts to humanity while also identifying what must be corrected. Such applications benefit psychologists in clinical cases and as they consider theoretical frameworks. When used together, these tools encourage us to anticipate both the true, good, and beautiful things in the world and the need at times for redirection. …

Amazon rainforests face intensifying water stress due to increases in vapour pressure deficit and changing hydrological regimes. Embolism resistance (Ψ₅₀) is a critical metric of tree survival under drought conditions, it is defined as a plant’s capacity to resist disruption of xylem water flow due to air bubble formation from water stress. However, measurements of Ψ₅₀ are only available for a limited number of Amazon locations and species. Conversely, data on forest taxonomic composition are abundant across Amazonia, and if Ψ₅₀ is conserved phylogenetically, these data could provide a way to scale-up drought resistance patterns. Here …

Amicus Brief In Trump V. Barbara: An Originalist Defense Of Birthright Citizenship, Jed Handelsman Shugerman, Evan D. Bernick

Faculty Scholarship

For nearly all of the first 235 years under the Constitution, the citizenship of every child born in the United States to alien parents, with immaterial exceptions, was a given. Then, in 2025, the Trump administration changed course. Even though the Fourteenth Amendment makes no mention of limiting birthright citizenship to the children of domiciled parents, the Government now claims that is what “subject to the jurisdiction thereof” has always meant. While the Government and its amici admit that the common law recognized the citizenship of children of transient aliens, their remaining “survey of history range[s] from the constitutionally irrelevant” …

Recognizing Structural And Social Determinants Of Health In The Diagnosis And Care Of Dementia, Shana D Stites, Sharnita Midgett, Nisha Patel, Kimberly Halberstadter, Rosalie Schumann, Marissa L Streitz, Yidan Shi, John C Morris, Jason Flatt, Crystal M Glover, Dawn Mechanic-Hamilton

2020-Current year OA Pubs

Structural and social determinants of health are environmental conditions that affect individuals' health and functioning across the life course. These determinants are salient factors at the apex of individual psychology, community variables, and larger sociological factors, exerting prominent effects on individuals' wellbeing. The National Institute on Aging seeks to understand their influence on aging and Alzheimer's disease. We propose that the benefits of doing so may reach beyond knowledge of disease mechanisms - it may also improve clinical outcomes. We describe efforts introducing structural and social determinants of health data into the national network of Alzheimer's disease research centers. We …

Bridging The Intention-Implementation Divide In Generative Ai Adoption: An Integrated Model Of Psychological, Behavioral And Social Drivers, Mohamed Walid Mohamed Lotfy Abdallah

USF Tampa Graduate Theses and Dissertations

This dissertation examines the gap between professionals’ intentions to use Generative Artificial Intelligence (AI) and their actual adoption behavior in workplace settings. Although Generative AI offers substantial potential to improve efficiency and performance, concerns about control, misuse and organizational risk have led to inconsistencies between intended and enacted use. Motivated by this misalignment, the study investigates the psychological, behavioral and social mechanisms that shape the intention-implementation divide. Drawing on an integrated framework combining the Theory of Planned Behavior and the Technology Acceptance Model, alongside personality traits, the research conceptualizes adoption as a phase-specific process involving evaluative, motivational and volitional components. …

Sensi-Train: Context-Aware Sensitive Content Detection Using Transformers And Large Language Models, Nazeefa Muzammil

USF Tampa Graduate Theses and Dissertations

The detection of sensitive content has become a critical task in natural language processing due to the widespread use of online platforms and the social harm caused by it. Even though current methods have advanced significantly, many of them mainly rely on surface-level text and neglect to take into consideration contextual and cultural elements that are crucial for correctly assessing sensitivity of any content to a particular individual. Due to this, implicit offense, sarcasm, and culturally grounded expressions frequently cause problems for such systems. To enable culturally grounded sensitive content detection, this thesis presents Sensi-Train, a context-rich dataset and modeling …
