More Hours, More Work: Head Start Expansions Boost Maternal Employment, Chloe R. Gibbs, Esra Kose, Maria Rosales Rueda

Upjohn Institute Working Papers

Women’s employment remains highly sensitive to childcare constraints, making childcare availability a critical lever for supporting mothers’ labor force attachment. We study the effects of expanded full-day programming in Head Start, using the 2016 federal funding initiative that targeted grantees with low full-day enrollment. Linking administrative program data, geo-coded center locations, and household data on employment, we estimate a difference-in-differences design by comparing mothers of young children in treated and untreated areas. The policy increased full-day enrollment by 19 percent and raised single mothers’ employment (1.9%), hours (2.5%), and earnings (6.5%). Results show that extending program duration meaningfully improves maternal …

The materials used to synthesize the electrodes were characterized by X-ray diffraction (XRD), which showed the successful synthesis of GO, rGO, and the Sb2O3-rGO composite. Additionally, the synthesized electrodes were examined using SEM. The MB degradation was studied using kinetic behavior and …

Veterans’ Living To Create Healthy Environments And The Meaning Of Their Well-Being: A Phenomenological Inquiry, Cheryl L. Birmingham

Creating Healthy Work Environments (CHWE)

The Veterans reside in a unique environment influenced by past military experiences that may have positive and negative effects on their well-being as Veterans. With nearly half of the 18.4 million Veterans in the United States living beyond 61 years the physical and mental health conditions may desolate the Veterans’ well-being. Promoting Veterans’ well-being has been studied extensively but scant research has been done on the environmental influences and how it helps to define It is critical to understand how Veterans define well-being to inform future program development addressing mental health needs. The purpose of this study is to discover …

Implementation Of A Mindfulness Intervention Among Professional Firefighters And The Effect On Perceived Stress Levels, Rachel L. Mowry

Creating Healthy Work Environments (CHWE)

Problem Statement: Firefighters experience high levels of stress related to their occupation that negatively impacts their physical and mental health and can lead to loss of occupation, decreased work productivity, and suicide. Occupational stress in firefighters impacts firefighters as individuals, as well as their places of work and communities; therefore, this phenomenon should be investigated further. Mindfulness is a strategy which is shown to be effective in the reduction of occupational-related stress. Mindfulness-based strategies can be delivered through a variety of methods including mindfulness-based stress reduction, mindfulness-based cognitive therapy, virtual mindfulness interventions, and other structured programs. Increased mindfulness has been …

Digital Services Taxes And The Wto, Reuven S. Avi-Yonah, Doron Narotzki

Articles

In an excellent Tax Notes article, Claudio Cipollini argues that the United States has adopted a paradoxical stance regarding digital services taxes. On one hand, the United States has repeatedly characterized DSTs as discriminatory trade barriers that unfairly target U.S. technology firms. On the other, it has systematically obstructed appointments to the Appellate Body of the WTO, leaving the dispute settlement mechanism effectively inoperative and ineffective. Cipollini presents this as a “missed WTO route,” suggesting that a functioning WTO system would primarily serve U.S. interests by disciplining European DSTs under the General Agreement on Trade in Services (GATS).

Enhancement Of Plastic Deformation In Ultrasound-Assisted Cold Spray Of Tungsten: A Molecular Dynamics Study, Md Tusher Ahmed, Farid Ahmed, Jianzhi Li

Manufacturing & Industrial Engineering Faculty Publications

Tungsten (W) is widely valued for its exceptional thermal stability, mechanical strength, and corrosion resistance, making it an ideal candidate for high-performance military and aerospace applications. However, its high melting point and limited room-temperature plasticity pose significant challenges for processing W using additive manufacturing (AM). Cold spray (CS), a solid-state AM process that relies on high-velocity particle impact and plastic deformation, offers a promising route for additive manufacturing of W, yet conventional CS fails to induce sufficient plastic deformation for effective bonding. In this study, we employ atomistic simulations to investigate the effect of ultrasonic perturbation in …

Relationship Between Navigation Success, Diagnostic Accuracy, And Ventilation Strategy: Retrospective Chart Review Of 224 Consecutive Navigational Bronchoscopic Procedures Performed Under General Anesthesia, Basavana Goudra, Prarthna Chandar, Divakara Gouda, Harrison Yang, Ganan Muhunthan, Suvan Sundaresh, Michael Stuart Green

Department of Medicine Faculty Papers

Background: Navigational bronchoscopy (NB) enables precise sampling of peripheral and central pulmonary nodules using shape-sensing or electromagnetic guidance. A major challenge is anesthesia-induced atelectasis, which alters lung anatomy, reduces registration accuracy, and is known to lower diagnostic accuracy. To counteract this, ventilatory protocols such as the Ventilatory Strategy to Prevent Atelectasis (VESPA) and the Lung Navigation Ventilation Protocol (LNVP) have been recommended. Their adoption and clinical impact, however, remain uncertain. Methods: We conducted a retrospective review of 224 consecutive NB procedures performed under general anesthesia at a single academic medical center (January 2020–August 2024). Demographic, anesthetic, and ventilatory data were …

Leveraging Graph Neural Networks For Explainable And Adaptive Seismic Risk Modelling (Work In Progress)), Shivam Tyagi, Musfira Jilani

Research Outputs: 2025-Present

Seismic risk modeling predicts the likelihood of earthquake occurrences in different regions over time. This presents a distinctive challenge as both the spatial structure of underlying geological features and the temporal evolution of seismic events must be accounted for accurately. In addition, for planners and decision-makers, it is essential that such models are not only accurate but also explainable. However, most existing models lack explainability, which limits their usefulness. This research proposes a novel graph neural network based seismic risk modeling methodology that is both explainable as well as adaptable, as it allows decision-makers the flexibility to choose the risk …

Eye Of The Beholder: Exploring Correlates Of Subjective Cognition In Older Adults With And Without Insomnia, Amy N. Costa

USF Tampa Graduate Theses and Dissertations

It is unclear how subjective cognition is related to current objective cognitive functioning in older adults, but subjective cognitive complaints are a risk factor for future cognitive decline. A lack of awareness of even subtle changes in objective cognitive performance could lead to missed opportunities for early intervention. Given past work and known associations between sleep, cardiac autonomic functioning, and cognition (both subjective and objective), it is plausible to hypothesize these factors may influence subjective cognition. Understanding how and when the subjective and objective cognition relationship diverges may inform clinicians on how to best assess cognitive functioning and factors (i.e., …

An Autoethnographic And Relational Exploration Of Identity Negotiation Within Romantic Relationships Between Nonbinary Partners And Cisgender Women, Maddison L. Russell

USF Tampa Graduate Theses and Dissertations

This dissertation explores how trans and cisgender partners negotiate gender identity, care, and relational well-being through an autoethnographic examination of everyday communication. The study draws from eighteen personal narratives across family, academic, and romantic contexts to trace how gender-based microaggressions and cisnormative expectations become embedded in ordinary talk, gestures, and silences, shaping identity development and relational stability. At its core, this work argues that relationality emerges as a pervasive and constitutive condition that shapes how affirmation, misrecognition, and belonging are experienced within trans/cis relationships and across time. Through examining moments of misunderstanding, minimization, and avoidance, the study reveals how microaggressions …

Metastatic Castrate-Resistant Prostate Cancer To The Penis Resulting In Malignant Priapism And Urethral Obstruction, Courtney Stewart, Joon Yau Leong, William Kevin Kelly, Mihir Shah

Department of Urology Faculty Papers

A 76-year-old male with metastatic castrate-resistant prostate cancer was found to have metastatic disease to the urethra and penis on PSMA PET scan. This resulted in constant pain due to obstruction of blood flow through the corpora cavernosum resulting in priapism and urethral obstruction. The patient underwent a radical penectomy, partial urethrectomy and perineal urethrostomy creation. Final pathology confirmed metastatic prostatic adenocarcinoma. Although rare, prostate cancer can metastasize to the corpora spongiosum or cavernosa. Treatment options are limited, and surgical excision with urinary diversion is likely to provide the most durable outcomes for one's quality of life.

Understanding Perceptions Of A Peruvian Local Market Program: A Reflexive Thematic Analysis, Rosmery Ramos-Sandoval Dr., Jano Ramos-Diaz

Enhancing Training For Law Enforcement In Mental Health Responses In The Community, Tiffany Raines

Walden Dissertations and Doctoral Studies

A significant issue in human services practice in Macon, Georgia, is law enforcement officers’ responding to individuals experiencing a mental health crisis in public. Many police officers are not equipped to handle situations involving individuals experiencing mental health events, leading to possible adverse outcomes such as injury, incarceration, or even fatalities. There are increasing rates of mental illness disorders, and therefore, the need for compassionate, informed approaches for human service professionals to respond to those in crisis. More training to improve responses can lead to better outcomes for individuals in crisis, foster community trust in law enforcement, and enhance overall …

Communicative Legitimacy: The Supreme Court's Hidden Cultural Binaries In The U.S. Civil Sphere, Steven Arrigg Koh

Faculty Scholarship

How does the U.S. Supreme Court establish its legitimacy? Over the last two hundred years in U.S. society, the Court has interpreted the U.S. Constitution on watershed issues such as slavery, segregation, and marriage equality. And yet the Constitution is just 7,591 words. A puzzle thus emerges: how does the Court intelligibly interpret this short text for U.S. society? This article develops a new theoretical and empirical cultural sociological account of such Supreme Court decision-making, which it calls “communicative legitimacy.” According to this theory, which draws on Jeffrey Alexander’s civil sphere theory, the Court consistently and inevitably draws on a …

Sting-Induced Blood-Brain Barrier Opening Combined With Radiotherapy Potentiates Antitumor Response In A High-Grade Glioma Model, Shashwat Tripathi, Hinda Najem, Lisa Hurley, Ruochen Du, Crismita Dmello, Kathleen Mccortney, Peng Zhang, Craig M Horbinski, Lara Leoni, Ryan J Avery, Rimas V Lukas, Timothy L Sita, David R Raleigh, Sean Sachdev, Roger Stupp, Maciej S Lesniak, David M Ashley, Daniele Procissi, Michael A Curran, Irina Balyasnikova, Amy B Heimberger

Faculty, Staff and Student Publications

Radiation therapy (RT) is the standard of care for glioblastoma but is not curative. Triggering the cGAS/stimulator of interferon genes (STING) pathway with potent agonists, such as 8803, exerts activity across high-grade glioma preclinical models. To determine if the combination of 8803 with RT warrants consideration in the up-front treatment setting and to clarify the underlying mechanisms of therapeutic activity, C57BL/6J mice harboring intracerebral CT-2A or QPP8v gliomas were treated with RT, intratumoral 8803, or both. The treatment with the combination resulted in 80% long-term survival in the CT-2A model but not in the radiation-resistant QPP8v model. This therapeutic effect …

Automated Quantification Of Movement Qualities In The Human Upper Extremity After Stroke Using A Wearable Robot., Yoon No Gregory Hong, Kyoungsoon Kim, Sheng Li, Marcia K O'Malley, Ashish D Deshpande, Jinsook Roh

Faculty, Staff and Student Publications

Background: Stroke is a leading cause of long-term adult disability, with approximately 80% of survivors experiencing upper extremity (UE) motor impairments. Conventional tools like the Fugl-Meyer Assessment (FMA) are widely used but limited by ordinal scales and subjective visual observation. While wearable robotics offer high-resolution data, their clinical translation is hindered by a lack of standardized protocols and limited interpretability for clinical decision-making.

Objective: This study aimed to develop an objective, standardized, and clinically interpretable method to quantify UE motor qualities by integrating wearable robotic technology with traditional clinical assessment tasks.

Methods: Ten healthy individuals and ten stroke survivors performed …

Discourses On Homosexuality And The Paradox Of The Closet In The New Life (2023) By Tom Crewe, Paramita Ayuningtyas, Shuri Mariasih Gietty Tambunan, Asri Saraswati

Bahasa dan Seni: Jurnal Bahasa, Sastra, Seni, dan Pengajarannya

This article offers a critical examination of Tom Crewe's biographical novel The New Life (2023), focusing on its representation of homosexual subjectivity in Victorian England—a historical context defined by restrictive moral norms and punitive legal regimes that criminalised same-sex relationships. Drawing on Michel Foucault's theory of discursive power, Eve Kosofsky Sedgwick's concept of the closet, and Michael Boucai's topology of the closet, the study demonstrates that the novel portrays the closet not merely as a private site of concealment but as a complex social mechanism shaped by legal regulation, gender norms, and class-based power relations. Building on this theoretical framework, …

A 682-Second X-Ray Periodicity In Ch Cygni: Evidence For A Magnetic White Dwarf, Manuel Pichardo Marcano, Thomas J. Maccarone, Liliana E. Rivera Sandoval

Physics & Astronomy Faculty Publications

Symbiotic stars are interacting binaries consisting of a red giant and typically a white dwarf (WD), which are important as potential Type Ia supernova progenitors. Despite theoretical predictions that WDs in symbiotic systems should often be magnetic, direct evidence has been elusive. We report the discovery of a 682.5 ± 7 s periodicity in the XMM–Newton X-ray light curve that we interpret as the spin period of the WD in CH Cygni. This detection provides strong evidence for a magnetic WD in CH Cygni, making it only the second WD symbiotic star with confirmed X-ray pulsations after R Aquarii. Our …

Adapting To Cultural Diversity At Work: A Thematic Analysis Of Resources Mobilized By Local And Posted Agricultural Workers In France, Alexandrine Ceschiutti, René Mokounkolo

The Qualitative Report

When workers have to adapt to a new culture, they develop intercultural skills as cultural intelligence (CQ), which is the ability to show an interest and act effectively in an environment characterized by cultural diversity. There has been little research on this subject in France, and studies have focused on expatriates, while acculturation also affects people from the local community. This is the case for local agricultural workers (LW), whose perceptions we compare with those of foreign posted agricultural workers (PW) in France. Our study had two aims: (a) to explore the personal resources that these workers perceive as necessary …

On-Orbit Correction Of Ecostress Radiances By Comparison With Iasi Hyperspectral Sounders, David S. Wethey, Sarah A. Woodin, Jorge Vazquez-Cuervo

Faculty Publications

Radiance data from ECOSTRESS (ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station), which is the first of a planned virtual constellation of wide-swath ultra-high-resolution thermal satellites, were used to test the concept of on-orbit cross-calibration based on the Global Space-based Inter-Calibration System (GSICS) with the Infrared Atmospheric Sounding Interferometer (IASI) as the reference. Validation of the results was performed using comparisons of corrected ECOSTRESS radiances with strictly independent data from IASI and the Cross-Track Infrared Sounder (CrIS) and with RTTOV radiative transfer simulations of clear-sky observations in iQuam (the NOAA in situ sea surface temperature quality monitor database). ECOSTRESS has …
