An Acoustofluidic Device For Sample Preparation And Detection Of Small Extracellular Vesicles, Jessica F. Liu, Jianping Xia, Joseph Rich, Shuaiguo Zhao, Kaichun Yang, Brandon Lu, Ying Chen, Tiffany Wen Ye, Tony Jun Huang

Faculty Publications

Small extracellular vesicles (sEVs) have emerged as powerful vectors for liquid biopsy, offering a noninvasive window into the dynamic physiological and pathological states of the body. However, to fully leverage the clinical potential of sEV biomarkers, it is imperative to develop robust and efficient technologies for their isolation and analysis. In this study, we introduce a novel sharp-edge acoustofluidic platform designed for rapid and effective sample preparation, coupled with sensitive detection of specific sEV populations based on their surface markers. Our approach utilizes acoustically activated sharp-edge microstructures to concentrate bead-bound sEVs within the microfluidic device, facilitating immediate visualization by fluorescence …

Comunidades Y Vacunas: Findings On Vaccine Hesitancy In Latine Families With Autistic Children, Danica Leticia Limon-Mialkowski

Theses and Dissertations

Parent vaccine hesitancy (VH) and subsequent vaccine refusal for children has escalated in the U.S. over the past several years and is more common among parents with an autistic child compared to the general population (Zerbo et al., 2018). This is an important issue to address given that VH has led to a resurgence of vaccine-preventable diseases (DeStefano & Shimabukuro, 2019; Geoghegan, et al., 2020). Research shows that VH is affected by parent cultural background (Fombonne et al., 2020) and that minoritized groups are more likely to experience VH (48.1% in parents of color [POC] groups versus 22.9% in White …

Picture This: An Event Designed To Increase Awareness Of And Empathy For Individuals Who Experience Scrupulosity, Savannah M. Travis

Undergraduate Honors Theses

Scrupulosity, also known as religious OCD, is often misunderstood and under-recognized by those who have experienced it. This research adopts an interdisciplinary approach, integrating experience design theories and frameworks with research on scrupulosity, to develop an event that aims to increase awareness and empathy among attendees for individuals who experience scrupulosity. The experience design frameworks applied include the design thinking process, the self-determination theory, and the experience-type framework. Current research suggests that there is a need for further research on the case studies and qualitative phenotypes of individuals who have experienced scrupulosity, which this study aims to address.

Investigation Of The Isbr Method With A Quad Detector For The Measurement Of Turbine Rotor Inlet Temperature, A. Cole Cecil

Theses and Dissertations

Temperature measurements at the inlet of a gas turbine inlet have proven challenging due to the high flow velocities, limited space, and high temperatures. This work investigates the use of the Integrated Spectral Band Ratio (ISBR) method to measure temperature using a new set of gas bands and a new method for collecting, measuring m and converting raw signals to digital temperature data at low cost and high speed (4 Hz). The Pressurized Oxy-Coal (POC) reactor was refurbished and used in this work to simulate turbine inlet conditions. The POC was modified to produce a stable natural gas and air …

Impact Of Telehealth On Outcomes In Daily Practice, Shannon Stuebs

Theses and Dissertations

While telepsychology has existed in various forms for years and has been researched since the 1960s (Abrams, 2020), it was not until the COVID-19 pandemic that telepsychology started to be widely used. Prior to the COVID-19 pandemic, one study found that psychologists conducted only around 7% of their work via telepsychology, a number that jumped to over 85% in response to COVID-19 (Pierce, Perrin, Tyler, et al., 2020). While there has been a significant increase in the research exploring the efficacy of telehealth since the start of the pandemic (Lin et al., 2022), further research regarding long-term impacts and specific …

Exploring Sub-Protocols For Spectrum Cooperation And Transparency, Ashton Palacios

Theses and Dissertations

With the proliferation of terrestrial and space-based wireless radio frequency transmitters and receivers in recent years, there is a greater need for spectrum cooperation and transparency. Spectrum is a limited resource that is shared between all wireless devices, both active and passive. The spectrum needs of today and tomorrow demand new techniques to enable cooperation and device transparency. This dissertation explores an innovative field, wireless sub-protocols, that provides novel software solutions for spectrum cooperation and transparency. The first application is radio astronomy. Radio astronomy deploys highly sensitive, passive RF receivers to capture faint signals from distant celestial bodies. Because passive …

A Contentious Bond: The Mother-Daughter Relationship, Amelia Hapgood

AWE (A Woman’s Experience)

It is a tale as old as time: a mother and daughter, struggling to understand and outdo the other, not realizing the uniformity between them. They are duplicates, coded with the same DNA. The daughter strives to become more than her mother, and her mother watches and witnesses everything that she could have become. It is a battle for power, to be seen and verifiable. They bicker, yell, and cry, often unable to find common ground. Greta Gerwig coined this concept perfectly in her film Lady Bird, where the featured mother and daughter cannot do anything but scream at …

For The Enemy Is No Longer Men, But Our Own Sisters: Anti-Era Activists Within The Feminist Narrative, Grace Chipman

AWE (A Woman’s Experience)

When Alice Paul drafted the Equal Rights Amendment (ERA) in 1923, she had hoped it would become a unifying document for women across America. However, forty-nine years later, when Congress passed the amendment, radical feminists led the charge for its ratification. Paul, a prominent feminist, feared that the amendment became so politicized it was tearing apart the women’s movement. Dianne Fife Kay, an anti-ERA activist, described the period as a time in which “the enemy was no longer men, but our own sisters.” As Paul had feared, radical feminism had ruptured the sisterhood that first-wave feminism created.

Teaching Verbs Of Motion In A Task-Based Russian As A Foreign Language (Rfl) Course, Joan Castellví, Elena Markina

Russian Language Journal

The paper focuses on one of the most complex topics in Russian as a Foreign Language (RFL) instruction: verbs of motion (VoM). We introduce an innovative approach to teaching these verbs, grounded in Task-Based Language Teaching (TBLT), and contrast it with the traditional approach that follows the Presentation-Practice-Production (PPP) framework, which has dominated the field until now. By analyzing a sample of widely used textbooks specializing in VoM, we show that introducing the VoM system—specifically, the sequence in which the verbs are presented—follows the PPP design and is primarily grammar-oriented. This approach is based on the concept of “directionality,” which …

Russian Verbs Of Motion In L2 Acquisition: Testing The Efficacy Of A Usage-Based Approach, Tobias-Alexander Herrmann

Russian Language Journal

Unprefixed Russian motion verbs present unique challenges for second language (L2) learners as they encode distinct types of motion events. Traditional, directionality-based methods of teaching these verbs have faced criticism, prompting the adoption of alternative, cognitively informed approaches. This article builds on usage-based methodologies, such as those proposed by Nesset and Janda (2022), to investigate whether teaching unprefixed verbs of motion (UVoMs) as constructions can enhance L2 instruction. Using the frequent UVoM pair idti and xodit′ , both meaning ‘walk’, as a case study, I pursue two main goals. First, drawing on corpus data, I examine the construction UVoM + …

From Gesture To Coded Knowledge: Rediscovering And Redefining Tpr When Teaching Russian Motion Verbs In An Outdoor Classroom, Elena Susanna Weygandt

Russian Language Journal

The necessity to move my Russian as a second language (L2) classroom in an event tent during the “main” pandemic year encouraged me to create lessons engaging students’ movement and thus rediscover the Total Physical Response (TPR) method. This article presents the case for using TPR-inspired teaching as a mode to be considered in instruction of Russian verbs of motion (VoM). TPR, a teaching method and language acquisition theory suggested by James Asher in the 1960s, has further evolved in TPR role-playing and TPR storytelling and is used in L2 instruction today (e.g., Cook, 2008, p. 132; Davidheiser, 2002; Elliott …

Directionality Of Motion In Second Language Acquisition: With A Focus On L1-Korean L2-Russian Speakers, Hakyung Jung, Hyug Ahn, Jacee Cho

Russian Language Journal

This paper examines L2 acquisition of directionality of Russian motion verbs by L1-Korean speakers in terms of Slobin’s (1996) Thinking-for-Speaking (TFS) hypothesis and the markedness principle. Although directionality is lexically encoded in the verb in both Korean and Russian, the organization of this concept differs. In Russian, directionality is categorized solely by the feature [+/- directional], whereas in Korean, motion event expressions are distinguished not only by [+/-directional] but also by [+/-multi]. Experiments on L1-Korean, L1- Russian, and L1-Korean L2-Russian speakers demonstrated that (i) in Korean, the presence or absence of an explicit goal plays an important role in verb …

Introduction To The Special Issue: Searching For Alternative Approaches To Conceptualizing And Teaching Russian Verbs Of Motion: Bridging Linguistics And Teaching Practice, Maria Bondarenko

Russian Language Journal

This special issue seeks to account for the current status of an emerging trend we have observed in linguistics and L2 instruction over the last two decades: reconceptualizing Russian verbs of motion (VoM). To contextualize the contributions to the issue, in this Introduction, I will give an overview of how this trend has evolved from its inception until the present time, delineating within it two successive stages called the Cognitive Turn and Instructional Turn.

A Pedagogical Analysis Of How Unprefixed Verbs Of Motion Are Presented In Instructional Materials For Beginner Russian Language Learners, Elena Petrova, Kris Lewis

Russian Language Journal

It is well-known that verbs of motion (VoM) are quite challenging for Russian language learners. We analyze four VoM-specific pedagogical materials (three textbooks and one mobile application) for their usefulness in supporting second language acquisition and the development of new thinking-for-speaking (TFS) patterns in beginner-level Russian language learners. Focusing on directionality, scaffolding, comprehensible input, the use of visuals, and communicative activities, we highlight how these materials lay a foundation for understanding VoM but are not sufficient for helping learners fully develop new TFS patterns. We pose recommendations for future research, teaching, learning, and materials development in the area of Russian …

Alcohol & Substance Abuse Among Youth In South Africa, Carsyn R. Richins

Journal of Nonprofit Innovation

South Africa is one of the riskiest drinking countries in the world, and its youth show some of the highest alcohol and substance abuse rates in the nation. In recent years, consumption rates among South African youth have increased while the average age of first use has decreased. This has led to higher levels of binge drinking, addiction, and dependency. This paper explores the root causes and long-term consequences of this growing issue. It argues that three primary factors — early and frequent exposure, poor governmental regulation, and the use of substances as a coping mechanism — have created a …

Disinformation Attacks And Nonprofit Communication Strategies, Elise Lael Kieffer, Kevin M. Carr

Journal of Nonprofit Innovation

This study explores how disinformation attacks on social media can affect nonprofit organizations, a topic that has received limited scholarly attention compared to similar impacts in the for-profit sector. Through a review of existing literature and two in-depth case studies—Save the Children and the American Red Cross—this research analyzes how nonprofit organizations are uniquely vulnerable to reputational damage in the face of disinformation. The case studies highlight different motivations behind disinformation campaigns, including political agendas and deliberate efforts to harm brand credibility, and assess the effectiveness of various response strategies, including denial, debunking, attacking the source, and public education. Findings …

Directivity And Sound Radiation Of Percussion Instruments And Harmonic Analysis Of The Alto Saxophone, Hanna Michelle Pavill

Theses and Dissertations

This thesis investigates how musical instruments radiate sound, with a focus on directional behavior under realistic performance conditions. High-resolution measurements using a rotating microphone array were used to study percussion and woodwind instruments, providing new insight into how design, excitation, and frequency content shape acoustic output. The first set of experiments analyzed the directivity of the bass drum, triangle, and open snare. Each instrument exhibited unique radiation patterns reflecting its structure and playing method. The bass drum showed dipole-like behavior at low frequencies, transitioning to omnidirectional spreading at mid frequencies, and increasingly irregular patterns at higher frequencies. The triangle, due …

Development Of Fiber Composite Joints To Improve Folding Of Deployable Arrays, Luke Q. Gardner

Theses and Dissertations

An origami-inspired deployable array, despite being commonly made from rigid materials, must be able to fold into its stowed configuration. This necessitates the employment of discontinuities between the panels of the array and the use of specialized joints to connect them. Compliant joints, with all their typical advantages, are useful in this application. Membrane hinges and lamina-emergent torsional (LET) arrays are two classes of compliant joints, or surrogate folds, which each feature unique benefits and drawbacks. Membrane hinges in principle are simple and flexible, providing a wide range of motion while experiencing little stress. However, perhaps their most robust variation, …

Fantasy Novels, Romance, And Book Boyfriends: Romantic Views And Expectations Of Young Adult Women, Kennedy Dawn Morris

Theses and Dissertations

Despite its drop in popularity, reading is a pastime that is enjoyed by many. As with other forms of media, there is the question of how consuming literature impacts individuals. This research study examines how reading fantasy novels impacts the romantic views and expectations of women in emerging adulthood. Social comparison theory and parasocial relationships were utilized in order to examine how young adult women compare their relationships and relationship ideals to those of fictional characters, as well as how young adult women decide which fictional relationships and/or characters are worth their admiration. The findings of this study suggest that …

An Implementation Study Of A Brief, Online Sexual Mindfulness Intervention At The Individual Partner Level: The Impact Of Prompting Practice On Implementation, Alexyss Lange

Theses and Dissertations

Prior research suggests frequent, scheduled, non-interactive text support enhances psychological outcomes and increases adherence to psychological interventions (Agyapong et al., 2020; Shalaby et al., 2022; Shim et al., 2017). Using a hybrid III implementation model, we recruited individuals in romantic relationships to test whether weekly reminders improved engagement with a sexual mindfulness intervention. We found no evidence that additional support increased intervention implementation. Although we aimed to assess acceptability, adoption, appropriateness, and feasibility as separate implementation outcomes, factor analysis indicated these variables cluster into two broader constructs: Readiness and motivation and discomfort and uncertainty. These factors did not differ between …

Unraveling The Relationship Between Sexual Shame And Father-Child Sex Communication, Hannah Mireya Brundage

Theses and Dissertations

This study sought to understand the relationship between father’s sexual shame and children’s sexual shame. Parents play a role in shaping their children’s behaviors and perceptions in regard to sexuality. Most of this research analyzed data from the viewpoint of the mother, missing the potentially unique perspective and influence of fathers. Using longitudinal survey data from 361 fathers-adolescent dyads, I proposed to study the relations between father sexual shame and child sexual shame, and the possible mediating role of father-child sex communication. I predicted that quality of sex communication, including controlling and open communication, would mediate father sexual shame and …

Enhancing Fault Tolerance In Tmr Soft Risc-V Fpga Socs Through Failure-Driven Mitigation Strategies, Andrew Elbert Wilson

Theses and Dissertations

Field-Programmable Gate Arrays (FPGAs) leveraging soft processors, particularly those implementing the open-standard RISC-V Instruction Set Architecture (ISA), are increasingly important for space missions due to their adaptability and reconfigurability. However, their susceptibility to radiation-induced Single Event Upsets (SEUs) presents significant reliability challenges, necessitating robust fault-tolerant strategies such as Triple Modular Redundancy (TMR). This dissertation evaluates the effectiveness of TMR-based mitigation techniques for Linux-capable soft RISC-V System-on-Chip (SoC) implementations deployed on SRAM-based FPGAs operating in high-radiation environments. Using a combination of deterministic fault injection and neutron radiation testing, this work identifies critical residual single-point failure modes that persist in TMR-protected designs. …

Linking Static And Dynamic Structures And Properties Of Materials With Computational And Mathematical Models, (Enoch) Sin Hang Ho

Theses and Dissertations

Terahertz (THz) spectroscopy is an effective technique to study and manipulate the structural dynamics of materials, due to its frequency range being very similar to the vibrational frequencies of collective atom motions in a host of materials. High-field and broadband THz radiation can be generated via optical rectification (OR) in nonlinear optical (NLO) crystals. The efficiency of OR response in an NLO crystal is determined by many factors, including molecular hyperpolarizability (β), 2nd order electric susceptibility (χ(2)), crystal structure, primary growth orientation, refractive index, absorption and phase matching condition. In this dissertation, I will focus on using computation methods and …

The Effects Of Caregiving For A Family Member With Alzheimer’S Disease, Megan Layton

Student Works

Alzheimer’s disease (AD) is a progressive disease that leads people with AD to become dependent on a family member. As the disease worsens, caregivers face an increase in responsibility and burden. There is a rising number of AD cases which will result in an increase of caregivers. Twelve articles were examined using the EBSCO database by using keywords such as “Alzheimer’s disease,” “caregiver burden,” “coping,” “assisted living,” and “grief.” An analysis of these articles indicated the complexities of caregiving for a loved one with AD. These complexities such as stress, decision-making challenges, changes in family dynamics, the adjustment to placing …

Quantum-Chemical Modeling Of Mechanisms And Selectivity In Open-Shell Organometallic Reactions, Michael T. Davenport

Theses and Dissertations

Quantum mechanical calculations have emerged as a powerful approach for directly evaluating reaction mechanisms and selectivity in transition metal-ligand complexes involving organometallic intermediates. Density functional theory (DFT) quantum mechanical methods enable the generation of potential energy surfaces and structures that define reaction mechanisms and allow for the evaluation of selectivity through statistical transition state theory. However, in certain cases, it is necessary to go beyond statistical treatments and incorporate atomic motion through molecular dynamics simulations. Additionally, many transition metal-mediated reactions involve unpaired electrons and spin state crossings. This dissertation focuses on the application of DFT-derived potential energy surfaces and molecular …

A Missionary's Memoirs: Mongolia Revisited, Isaac Smith

Undergraduate Honors Theses

This is my story. It is a very personal story, but one that I want to share with others. Although it takes place predominantly in Mongolia, it is not merely a story about Mongolia, or even the Mongolian people. It is not really even a story about me. What is it then? It is a story about faith and love. It is an attempt to better understand how the gospel of Jesus Christ intricately fits into people’s lives all over the world—even in Mongolia. It is a compilation of essays, of memoirs, of my experiences. It is a story about …
