Suppression of Higher Acoustic Harmonics by Application of Solid-Solid Periodic Layered Structure in Nonlinear Ultrasonics Nondestructive Evaluation Field

Description: Nondestructive testing (NDT) using ultrasound band 1-5 MHz, has been widely used for the early-stage detection of structural failure; however, it fails to detectf material degradation, fatigue, and microcracks. NDT with nonlinear ultrasound (NLU) can detect a microscopic discontinuity or imperfection that may be a source of the second harmonic in the reflected signal. In this research, we focus on creating a metamaterial band filter that filters out nonlinearities induced by the instrument itse… more

The Effects of Generational Stereotypes and Attribute Affirmation on the Collection of Audit Evidence

Description: As the workplace has evolved over the past few years, several studies have documented perceived differences in personalities, values, and preferences between generations in the workplace, including in public accounting. In this study, I examine whether exposure to a negative preconceived belief about a staff auditor's generation (generational stereotype) influences the affective state of staff auditors and ultimately causes them to reduce the extent to which they communicate with a client manag… more

How Receiving Communities Structure Refugee Settlement Experiences: The Case of Burmese Immigrants in DFW

Description: The Dallas-Forth Worth Metroplex (DFW) serves as a diverse resettlement location for globally displaced refugees. While research examines how the nation impacts refugee resettlement, studies that examine the role of the city and community in placemaking are still lacking. In city resettlement investigations, research often focuses broadly on advocacy and political movements rather than the impacts of local-level structures and policies. In this paper, I develop an evaluation model using Jenny P… more

On Sharp Permutation Groups whose Point Stabilizers are Certain Frobenius Groups

Description: We investigate non-geometric sharp permutation groups of type {0,k} whose point stabilizers are certain Frobenius groups. We show that if a point stabilizer has a cyclic Frobenius kernel whose order is a power of a prime and Frobenius complement cyclic of prime order, then the point stabilizer is isomorphic to the symmetric group on 3 letters, and there is up to permutation isomorphism, one such permutation group. Further, we determine a significant structural description of non-geometric sharp… more

Asymptotic Formula for Counting in Deterministic and Random Dynamical Systems

Description: The lattice point problem in dynamical systems investigates the distribution of certain objects with some length property in the space that the dynamics is defined. This problem in different contexts can be interpreted differently. In the context of symbolic dynamical systems, we are trying to investigate the growth of N(T), the number of finite words subject to a specific ergodic length T, as T tends to infinity. This problem has been investigated by Pollicott and Urbański to a great extent. W… more

"Doble Identidad"

Description: Doble Identidad conveys my experience as someone who struggles with their cultural identity. Through the expository modes of self-reflexivity, participatory, experimental, and poetics, the film displays the factors that molded my cultural identity. My childhood memories and interactions with my loved ones help me tell the story of how my cultural identity has and continues to leave me with feelings of inadequacy of not being Mexican or American enough.

Coercion and Consent among Employer-Sponsored and Dependent Visa Holders: A Study of Indian Workers in the U.S. Information Technology Sector

Description: Highly educated and skilled Indian nationals are the largest recipients of H-1B visas in the US. An employer must be willing to sponsor an H-1B work visa for the worker to continue to live and work in the US. This stipulation has granted US employers unprecedented power over H-1B visa holders, which can be understood as status coercion; employers have state-sanctioned power to threaten or discharge a worker from their status, i.e., visa status, which interconnects work and migration status. Whi… more

The Role of Counselor Trainees' Co-Regulated Mindfulness: A Cluster-Randomized Controlled Study

Description: Mindfulness is a practice that has the potential to help counseling students build a variety of skills that are necessary for clinical efficacy, including therapeutic presence, attunement, empathy, cognitive flexibility, and non-reactivity. However, mindfulness is rarely taught to students in mental health training programs, which makes it an untapped possibility to improve counselor education. Additionally, rarely do researchers explore the role of counselor mindfulness and counselor trauma on… more

Development of Biomimetic Human Lung Alveolus Chip

Description: The potential of physiologically relevant in vitro cell culture models for studying physiological and pathophysiological phenomena has been widely recognized as replacements for animal and conventional in vitro models. To create models that accurately replicate the structure and function of tissues and organs, it is essential to comprehend the biophysical and mechanical features of the extracellular matrix (ECM) and incorporate them into the in vitro cell culture models. Therefore, we first aim… more

Extending the Capabilities of Continuum Embeddings in First-Principle Simulations of Materials

Description: In recent years, continuum models of solvation have had exceptional success in materials simulations as well as condensed matter physics. They can easily capture the effects of disordered systems, such as neutral liquids or electrolytes solutions, on material interfaces without the need for expensive statistical sampling. The Environ library (www.quantum-environ.org) implements different continuum models and correction schemes, which is the focus of this presentation. Recently refactored into a… more

"Seven Songs to Poems of James Joyce," op. 54 (1926) by Karol Szymaowski: A Historical Musicology Analysis and Performance Guide

Description: This research contributes valuable contextual information to the study of Karol Szymanowski's little-known song cycle Seven Songs to Poems of James Joyce, op. 54 (1926), providing a reliable, comprehensive reference for singers and scholars. In this research, I establish separate historical contexts for James Joyce's Chamber Music and Szymanowski's settings of the poems in op. 54. Using these established historical contexts, I then analyze Joyce's poems and Szymanowski's text settings, focusing… more

Survivor vs. Victim: Self-Labeling of Trauma Victims and Its Implicit Impact on Resilience and Recovery

Description: Past research demonstrates that participants who label themselves as ‘victims' experience worse trauma-related outcomes than those who label themselves as ‘survivors.' Self-labeling in trauma research is typically measured using a dichotomous measure where participants choose either victim or survivor, but this construct may be better conceived as more continuous. The current study assessed self-labeling as a possible continuous construct and explored its predictive validity. To capture self-la… more
