Writers' Program of the Work Projects Administration in the State of Texas, Fort Worth City Guide and History Draft Records

A transcript of an Ex-Slave Narrative interview conducted by Sheldon F. Gauthier for the Works Progress Administration's Federal Writers' Project in the 1930s with James Cape. Cape, who believed he was over 100 years old at the time of the interview, was born into slavery in southeast Texas on the cattle ranch of Bob Houston. His primary work while enslaved was as a horse wrangler and cowhand. He describes his work as a cowhand, including riding horses, cattle, stampedes, and trail drives. He also describes joining the Confederate Army to care for the horses, but later being forced into fighting …

The Legal Regulation Of E-Commerce In Lebanon, Dolly Abouchakra

BAU Journal - Journal of Legal Studies - مجلة الدراسات القانونية

In the digital age, the economy and commerce sectors in Lebanon, as well as globally, have embraced advancements, leading to the emergence of e-commerce with its multifaceted models, thereby establishing the electronic commercial entity. These advancements necessitate a profound technological transformation, which, in turn, introduces critical legal challenges. These challenges threaten the stability and growth of such entities within traditional legal frameworks that are insufficiently equipped to address the complexities of the digital environment and the noticeable absence of specialized regulations. This study highlights the inadequacy and disjointed nature of the Lebanese legal framework governing electronic commercial entities. The current …

Belonging Starts With You: Exploring Trust, Belonging, And Spiritual Connection In The Success Of Culturally Diverse Students In Higher Education, Moises Aguirre

Theses and Dissertations

Cultivating trust and belonging is essential for student success in higher education, particularly for students from diverse cultural backgrounds (DCB) who face unique challenges in developing these connections. Research highlights lower levels of trust reported by DCB students toward peers and institutions, adversely impacting their academic performance and social integration (Van Maele & Van Houtte, 2010). The urgency of these issues is underscored by the demographic evolution in Utah's educational system, with projections indicating significant growth of students' diversity by 2065 (Hollingshaus et al., 2019). Because of these projected developments, this study investigates how DCB students conceptualize and experience trust …

What's The Joke Princess?: A Qualitative Analysis On The Comic Representation Of Women In Disney Sitcoms, Julia J. Lee

Theses and Dissertations

This thesis investigates the comedic representation of women in recent Disney sitcoms (2019"“2025), focusing on the framing devices, stereotypes, and situational contexts through which gendered humor is constructed and reinforced. Drawing from existing literature on comedic archetypes, the study identifies six historically dominant comedic frames and reveals eleven emergent subframes that complicate, reinforce, or expand these traditional portrayals. Through qualitative content analysis and systematic coding of selected Disney sitcoms, this study identifies consistent character traits and comedic techniques that span multiple frames and contexts, revealing how these patterns influence audience perceptions of femininity. The study situates these frames within three …

Discovering And Designing Novel Perovskite Photovoltaic Materials Via Machine Learning, Junyeong Ahn

Discovery Undergraduate Interdisciplinary Research Internship

Perovskite semiconductors are promising materials for high-efficiency photovoltaics due to their outstanding optoelectronic properties, emerging as a sustainable energy source through solar cell applications. Perovskites with the ABX₃ composition (A, B = metal or organic cations with varying oxidation states; X = chalcogen or halogen anions) have gained interest for their excellent phase stability and compositional tunability. However, combinatorial possibilities arising from the many choices of A, B, and X site species, and their respective mixing fractions, a large number of possible ABX₃ perovskites remain undiscovered. In this work, we used machine learning (ML) methods to design new stable and …

Is There A More Effective Design For Quadrat To Increase Ease Of Use And Vegetation Density?, Scott M. Burke Jr., Kristen M Bellisario

Discovery Undergraduate Interdisciplinary Research Internship

Quadrats are a special tool in the ecology field that allows the measurement of vegetation density for further data analysis of a habitat. The larger the quadrat cross-sectional area, the better the results of the data, which in turn can make the quadrat hard to carry through field sites. In wildlife corridor research, quadrat surveys provide a quantitative metric for habitat suitability. In this work, we consider the efficiency and ease-of-use benefits for field work in the design of a collapsible version of a quadrat using a House of Quality (standard metric for new design requirements) to assess the customer …

“Falling Short Of Our Humanity”: Shame And Queer Catholic Families, M.T. Davila

Religious & Theological Studies Faculty Publications

Queer Catholic Families (QCF) negotiate a complicated landscape of belonging and exclusion in the church that they love. In this dynamic, shame figures as a theological and moral qualifier of their experience when observed through the lens of the Catholic Church's teaching on sexuality and gender. Understanding how shame is experienced in these families, how it deepens a rift between families and the community, and how families find ways to nourish and preserve their links to the Church, ought to be a primary ethical and pastoral task of the Church.

Investigation Of The Influence Of Warhead Shape And Type Of Missile Weapon Material Counter-Training Tank Weapons Simulation Approach, Transisma Budiarta, Haris Puspito Buwono, Radhi Nurvian Amrullah

Journal of Mechanical Engineering Science and Technology (JMEST)

This study analyzes the effect of warhead shape and material variations on pressure, temperature, and lift on training missiles using CAD-based simulation methods. The variations of warhead shapes tested include flat, flat radius, and tapered, while the materials used are rubber, ABS, and PE. The simulation results show that the tapered warhead shape with PE material produces the lowest pressure (50.3 MPa) due to more efficient pressure release and low friction properties. Conversely, the Flat shape produces the highest pressure (69.1 MPa) on all materials due to flow stagnation. In terms of temperature, the Flat Radius warhead with PE and …

Characterization Of Curcumin As A Coating Material For Polymer-Free Stents Interms Of Morphology And Release, Ameliyana R.S.P.A. Yani, Muhammad Kusumawan Herliansyah

Journal of Mechanical Engineering Science and Technology (JMEST)

The use of bare metal stents over the long term often leads to the re-narrowing of blood vessels, prompting a shift to drug-eluting stents (DES). However, the use of polymers in DES has been known to trigger inflammation and thrombosis in the arteries. As an alternative, polymer-free drug-eluting stents (PF-DES) have emerged as a safer option. In this study, curcumin was selected as the primary coating material for PFDES using the electrophoretic deposition method. The effects of varying curcumin concentrations (125 µg/ml, 250 µg/ml, and 500 µg/ml) were examined to understand their impact on deposition morphology, coating weight, chemical bonding …

Unmasking The Heart Of Osimertinib: A Closer Look At Drug-Induced Cardiotoxicity, Muhammad Sabri, Aheed Javaid, Hussam Al Hennawi, Hamza Muhammadzai, Vamshi Mallavarapu

Abington Jefferson Health Papers

BACKGROUND: Osimertinib, a third-generation epidermal growth factor receptor tyrosine kinase inhibitor, is an effective therapy for epidermal growth factor receptor-mutated non-small cell lung cancer, but it has been associated with a higher incidence of cardiotoxicity.

CASE SUMMARY: A 91-year-old woman on osimertinib 80 mg daily presented with acute dyspnea and was found to have a newly reduced left ventricular ejection fraction of 30%. Coronary angiography excluded obstructive coronary disease. Osimertinib was discontinued, and guideline-directed medical therapy (GDMT) was initiated, resulting in left ventricular ejection fraction recovery to 60%. The patient was successfully rechallenged with osimertinib while continuing GDMT, without recurrence …
