Native Ticks As A Model For The Effectiveness Of Fire As A Tool For The Management Of Cattle Fever Ticks In South Texas, Lauren P. Maestas, Sarah E. Mays Maestas, Kathleen M. Yeater, Manuel Zavala, Reyes Garcia, John A. Goolsby

School of Integrative Biological & Chemical Sciences Faculty Publications

The species of cattle fever ticks (CFT) present in North America, Rhipicephalus (=Boophilus) annulatus, and R. microplus, remain an important agricultural and economic burden. The use of acaricides to control CFT has been a common practice over the past half century. However, alternative strategies for control are needed to improve the options for sustainable pest control. Fire is a tool to manage vegetation, and some evidence supports its potential for use to control ticks. We evaluated the effectiveness of fire as a management tool for ticks in South Texas. Our site was a 28.2-ha property in Cameron …

Menta, Antony A. Fuleihan, Kamel Chebaro, Jawad Khalifeh, Andrew Grossbach, Nicholas Theodore, Daniel Lubelski

Department of Medicine Faculty Papers

Spinal cord hemangioblastomas are rare, benign, intradural tumors that, despite their nonmalignant histopathology, can lead to substantial neurological morbidity. While disparities in outcomes based on race and socioeconomic status have been well-documented in other spinal tumor populations, their role in spinal cord hemangioblastoma remains poorly understood. In this study, we utilize the National Cancer Database (NCDB) to evaluate the influence of race, socioeconomic factors, and healthcare access on survival outcomes in patients with spinal cord hemangioblastoma. Additionally, we explore the utility of machine learning-based survival models to improve individualized risk prediction and to identify key clinical and sociodemographic determinants of …

Organizational Climate And Decision Aid Sustainability In Lupus Care: Mixed Methods Study, Aizhan Karabukayeva, Larry R Hearld, Nathan W Carroll, Reena Kelly, Jasvinder A Singh

Faculty, Staff and Students Publications

Background: Digital decision aids (DAs) are increasingly used in health care to support shared decision-making and promote patient engagement. In the context of systemic lupus erythematosus (SLE), a complex autoimmune disease characterized by diverse symptoms and uncertain prognoses, DAs offer guidance to patients in navigating treatment risks and benefits. Although numerous studies have examined the initial implementation of evidence-based tools, there is limited evidence on the organizational factors that influence their long-term sustainability in clinical practice. This gap is particularly salient for digital interventions, where integration into routine workflows and ongoing use require alignment with clinic readiness and culture. This …

Background: Invasive ductal carcinoma (IDC) is considered the most common form of breast cancer, accounting for a significant percentage of mortality worldwide. Therefore, its early detection is vital to further improve patients’ outcomes and survival rates. However, conventional diagnostic methods in the form of manual histopathological examinations are time-consuming, subjective, and prone to errors. Therefore, there is an urgent need to develop automated solutions for accurate IDC detection in histopathology images to assist pathologists in clinical decision-making. Objective: We aim to develop and validate a convolutional neural network (CNN) model for early detection of IDC by analyzing histopathological images. The …

Β-Catenin Functions As A Molecular Adapter For Disordered Cbaf Interactions, Yuen San Chan, Qinyu Gao, Sarah A Robinson, Wenzhi Wang, Ruzena Filandrova, Lisa-Maria Weinhold, Mario Loeza Cabrera, Miao Zhang, Chandra Shekar R Ambati, Antonio M Lerario, Nagireddy Putluri, Katja Kiseljak-Vassiliades, Margaret E Wierman, Mouhammed Amir Habra, Gary D Hammer, Vaclav Veverka, Katerina Cermakova, H Courtney Hodges

Faculty, Staff and Students Publications

BAF (SWI/SNF) chromatin remodelers engage binding partners to generate site-specific DNA accessibility. However, the basis for interaction between BAF and divergent binding partners has remained unclear. Here, we tested the hypothesis that scaffold proteins augment BAF's binding repertoire by examining β-catenin (CTNNB1) and steroidogenic factor 1 (SF-1, NR5A1), a transcription factor central to steroid production in human cells. BAF inhibition rapidly opposed SF-1/β-catenin enhancer occupancy, impairing SF-1 target activation and SF-1/β-catenin autoregulation. These effects arise due to β-catenin's role as a molecular adapter between SF-1 and an intrinsically disordered region (IDR) of the canonical BAF (cBAF) subunit ARID1A. In contrast …

The Law Of Diminishing Marginal Product Of Labor: Let Us Work To Nail It!, Shengnan Fang

Southwestern Business Administration Journal

In the post-pandemic, the transition back to in-person teaching presents a significant adjustment for both instructors and students.

Iraqi Journal for Computer Science and Mathematics

Digital watermarking is crucial in content identification and copyright protection, particularly multimedia and medical imaging. This paper introduces two novel hybrid watermarking methods, Entropy-Guided Singular Embedding (EGSE) and Entropy-Guided Hybrid Embedding (EGHE), that improve upon existing techniques by integrating entropy-based adaptive block selection with Particle Swarm Optimization (PSO) for dynamic embedding strength determination. Unlike traditional methods, which rely on fixed embedding regions or manual parameter tuning, the proposed approaches automatically identify high-entropy regions to embed watermark signals, ensuring stronger resistance to distortion while maintaining image quality. EGSE employs Integer Wavelet Transform (IWT) and Singular Value Decomposition (SVD), whereas EGHE enhances …

Expanding Occupational Therapists’ Role In Youth Adaptive Sports: A Comprehensive Guidebook, Alexandria K. Lannoo, Lesley Khan-Farooqi

Summer 2025 OTD Capstone Symposium

Children with disabilities are less likely to participate in adaptive sports or physical activity than typically developing children, despite the proven benefits adaptive sports provide for physical, social, and emotional well-being. Adaptive sports can be modified to accommodate a variety of ability levels and can improve quality of life (QoL) of children with disabilities through enhanced mobility, social participation, and self efficacy. However many occupational therapists (OTs) underutilize adaptive sports within their practice and are unaware of their role in promoting participation and of resources within their community. Guided by the Synthesis of Child, Occupational Performance, and Environment in Time …

Ineffective Parenting, Alexis Rian

Master of Arts in Human Services

Ineffective parenting can lead to long-term, severe, and lasting consequences for children. Children depend heavily on their primary caregivers for safety and to have their basic needs met. However, not all parents demonstrate positive parenting styles, whether due to a lack of knowledge, limited capacity, or simply a lack of interest. Parenting styles fall into four categories: authoritarian, authoritative, permissive, and uninvolved. The type of parenting style a caregiver adopts can significantly influence the attachment style a child has with them. Four attachment styles that children have are insecure avoidant attachment, secure attachment, insecure resistant attachment, and disorganized attachment. Children …

The results showed that current and former foster youth face many adversities …

Not In My Neighborhood! The Harsh Realities Of Sex Offender Registration Laws, Kyle B. Rossow

Master of Arts in Human Services

Sex offender registration laws were created in response to public fear and high-profile tragedies, with the primary goal of enhancing public safety through stringent monitoring of sexual offenders. This paper explores the historical development of these laws, including high-profile cases that later influenced legislative acts, such as the tragic incidents of Jacob Wetterling, Megan Kanka, and Adam Walsh. This paper also explores how media portrayals and public opinion factor into these legislative decisions. While the laws aim to protect the public, they often result in collateral consequences for individuals who have to register. Sex offenders are often held back by …

A Religious Etiology Of Genito-Pelvic Pain And Pain With Penetration, Emily L. Carlson

Theses and Graduate Projects

Pelvic pain during penetration (PPDP) has been described using various diagnostic terms, including vaginismus, dyspareunia, and vulvodynia. The most recent and comprehensive classification is Genito-pelvic pain/penetration disorder (GPPPD) which is characterized by psychological distress associated with pain during or in anticipation of vaginal penetration (DSM-5-TR; American Psychiatric Association [APA], 2022). The etiology of PPDP is multifactorial, involving a complex interplay of biological, psychological, and relational factors. Religious and cultural influences may play a significant role in shaping individuals’ experiences of sexual pain. This study investigated the etiology of PPDP in relation to the religious influences among women raised in Judeo-Christian …

Menopause-Related Changes In Sleep And The Associations With Cardiometabolic Health: A Narrative Review, Joshua R. Sparks, Xuewen Wang Ph.D., Faha

Faculty Publications

This narrative review examines the complex relationship between sleep changes during the menopausal transition and cardiometabolic risks. The most common complaint about sleep is increased awakenings during sleep. Other complaints include having trouble falling asleep, waking up too early, insufficient and non-restorative sleep, and overall poor quality. Sleep determined using objective methods also indicates that greater awakenings after sleep onset are associated with the period of menopausal transition. Polysomnography recordings suggest physiological hyperarousal during sleep. Changes in other sleep metrics, such as sleep latency and sleep duration, are less consistent, and some studies suggest they may not worsen during the …

Dynamic Remodeling Of Centrioles And The Microtubule Cytoskeleton In The Lifecycle Of Chytrid Fungi, Alexandra F Long, Krishnakumar Vasudevan, Andrew Swafford, Claire M Venard, Jason E Stajich, Lillian K Fritz-Laylin, Jessica L Feldman, Tim Stearns

Biology Faculty Publications

Cell movement and division are complex behaviors driven by a dynamic internal cytoskeleton. The molecular components and principles of cytoskeletal assembly are well studied, but less is known about cytoskeletal remodeling events, including how centrioles transition from ciliary base to centrosome. Here we address this using the chytrid Rhizoclosmatium globosum, a zoosporic fungus which has centrioles and cilia, lost in most fungal lineages. Chytrids undergo reorganization of their microtubule cytoskeleton as they grow from zoospore to multinucleated coenocyte. We use evolutionary comparison, RNA sequencing, and expansion microscopy to understand this reorganization and further develop this organism as a model for …

Fatal Facial Necrotizing Fasciitis: A Case Report Highlighting Diagnostic And Therapeutic Challenges, Muhammad Sheraz Hameed, Syed Rafay Hussain Zaidi, Ali Iqbal, Muhammad Ahsan, Austin Mitchell, Azka Asad Mirza, Joshiah Gordon, Rahmat Gul Omarzai

Department of Medicine Faculty Papers

BACKGROUND: Facial Necrotizing Fasciitis (FNF) is a rare but aggressive, life-threatening infection involving the face's subcutaneous tissues and underlying musculature. It can rapidly progress to septic shock and multi-organ failure if not promptly recognized and treated. The clinical course, including severe pain, disproportionate tenderness, and systemic signs, is often the most crucial factor in diagnosis. While computed tomography (CT) can aid in identifying early signs such as soft tissue swelling and gas formation, clinical suspicion remains paramount and should not be delayed by reliance on imaging alone. Without early intervention, FNF may lead to devastating outcomes, including disfigurement, blindness, or …

Effects Of Summer School Attendance On The Assessed Reading Proficiency Of Third Grade Students, Lydia Evers

Walden Dissertations and Doctoral Studies

Evidence shows students who are not reading proficiently by the end of third grade are more likely to eventually drop out of high school or be considered illiterate as adults, making it challenging to function adequately in society. The problem addressed through this study was that as many as 60% of U.S. third-grade students scored below proficiency on annual standardized reading assessments. Guided by faucet theory by Alexander et al., the purpose of this causal-comparative quantitative study was to compare reading standardized test scores of third-grade students who participated in a summer school program (SSP) in the summer following second …
