Impact Of Telehealth On Outcomes In Daily Practice, Shannon Stuebs
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 …
For The Enemy Is No Longer Men, But Our Own Sisters: Anti-Era Activists Within The Feminist Narrative, Grace Chipman
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.

Cell-free protein synthesis (CFPS) has transformed protein production capabilities by eliminating cellular constraints, enabling the rapid expression of difficult-to-produce proteins in an open, customizable environment. As CFPS applications expand from fundamental research to industrial production, therapeutic manufacturing, and point-of-care diagnostics, the diverse array of reactor formats has become increasingly important yet challenging to navigate. This review examines the evolution and characteristics of thirteen major CFPS reactor formats, from traditional batch systems to advanced platforms. The historical development of CFPS reactors from the 1960s to present day is presented. Additionally, for each format, operational principles, advantages, limitations, and notable applications are …
A Pedagogical Analysis Of How Unprefixed Verbs Of Motion Are Presented In Instructional Materials For Beginner Russian Language Learners, Elena Petrova, Kris Lewis
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
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 …
A Call For Change: Supporting Children With Tourette Syndrome, Matt Reall
A Call For Change: Supporting Children With Tourette Syndrome, Matt Reall
Journal of Nonprofit Innovation
Tourette Syndrome affects 1 in 100 U.S. children but remains widely misunderstood due to stigma, delayed diagnosis, and media misrepresentation. This neurological disorder is characterized by involuntary tics and often co-occurs with ADHD, anxiety, and sleep disorders. Children with Tourette Syndrome face disproportionate challenges in social, academic, and emotional settings—despite having average or above-average intelligence. One-third engage in self-harm, and suicide rates are four times the national average. Peer-education programs like the Tourette Association of America’s Youth Ambassador initiative have shown promise in reducing stigma, but unequal access and weak institutional support limit their impact. This paper calls for early …
Disinformation Attacks And Nonprofit Communication Strategies, Elise Lael Kieffer, Kevin M. Carr
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
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
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, …
Who's At Home?: Individual-And Family-Level Sociodemographic Characteristics Associated With Stay-At-Home Motherhood, Deegan Minchey
Who's At Home?: Individual-And Family-Level Sociodemographic Characteristics Associated With Stay-At-Home Motherhood, Deegan Minchey
Theses and Dissertations
In this study, I assess the relationship between various types of demographic variables, including individual, partner, and family-level information, and the likelihood of mothers staying at home. Using nationally representative data from the 2019,2021, and 2023 waves of the Annual Social and Economic Supplement (ASEC) to the Current Population Survey to account for differences across the COVID-19 pandemic, this analysis examines the likelihood of becoming a stay-at-home mother (SAHM) across three separate regression models. From the variables analyzed, I find that various individual, family, and partner demographic characteristics are significantly associated with the likelihood of becoming a SAHM. These results …

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 …
Contaminant Removal Of Printed 7xxx Aluminum Using The Additive Friction Stir Deposition Process, Jacob Jason Hansen
Contaminant Removal Of Printed 7xxx Aluminum Using The Additive Friction Stir Deposition Process, Jacob Jason Hansen
Theses and Dissertations
The development of contaminant-free additive friction stir deposition (AFSD) using 7xxx series aluminum alloys represents a significant advancement in solid-state additive manufacturing. The removal of graphite and other contaminants allows AFSD to more effectively move forward into the production space. This work demonstrates how contaminant-free depositions were made more feasible. This was accomplished via novel tool designs. These novel designs reduced process forces sufficiently that 7xxx aluminum alloys were able to be printed on commercial and research AFSD machines. Internal features such as draft angles and diffusers/chamfers help to significantly reduce actuator forces. This work also demonstrates how external tool …

In this thesis, we present a comprehensive visual analysis of low surface brightness (LSB) structures in edge-on galaxies using two statistically complete samples: 838 galaxies from the SDSS Stripe 82 region (ES82) and 5,745 galaxies from the Edge-on Galaxies in SDSS (EGIS) catalog, both containing galaxies with spectroscopic redshifts out to 𝑧 ∼ 0.2. Using deep imaging data from the SDSS, SDSS Stripe 82, DESI Legacy Imaging Surveys, and the HSC-SSP, we construct RGB and coadded images for comparison and to improve feature detection. Average limiting photometric depth for each survey in the 𝑟 band for the surveys analyzed in …
Unraveling The Relationship Between Sexual Shame And Father-Child Sex Communication, Hannah Mireya Brundage
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
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. …
Applying Ceragenins In Translational Medicine: Activating Mesenchymal Stem Cells And Preventing Healthcare-Associated Infections, Aaron L. Zaugg
Applying Ceragenins In Translational Medicine: Activating Mesenchymal Stem Cells And Preventing Healthcare-Associated Infections, Aaron L. Zaugg
Theses and Dissertations
Healthcare-associated infections are a major global concern. Increased infections among vulnerable populations lead to millions of deaths, annually, complicated by the emergence of multi-drug resistant pathogens. These infections are often facilitated by medical devices serving as abiotic surfaces that facilitate the formation of biofilms. Notably, colonization of prostheses and other bone-associated medical devices can lead to corrective procedures, revisions and death. To address these issues, inspiration can be drawn from natural sources of bone health and defenses against infection. Cathelicidins are endogenous peptides involved in both bone maintenance and infection control. Ceragenins are small molecule mimics of cathelicidins with broad …
Linking Static And Dynamic Structures And Properties Of Materials With Computational And Mathematical Models, (Enoch) Sin Hang Ho
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 …
Predicting Single-Leg Eccentric Hamstrings Strength In Aging Athletes Using Diagnostic Ultrasound- And Survey-Derived Parameters, Lee J. Hinkle
Predicting Single-Leg Eccentric Hamstrings Strength In Aging Athletes Using Diagnostic Ultrasound- And Survey-Derived Parameters, Lee J. Hinkle
Theses and Dissertations
Introduction: Eccentric hamstring strength declines with age and contributes to mobility limitations. Although Nordbord testing quantifies eccentric strength, few studies have examined it in older adults, and none have predicted strength performance on this test using ultrasound or survey- based measures. Methods: We recruited 122 senior athletes (60 female) at the 2024 Huntsman World Senior Games. Ultrasound-derived cross-sectional area (CSA), echogenicity, and subcutaneous fat thickness, along with demographic and activity data, were used to predict single-leg peak force using Bayesian regression. Models were sex-stratified, and predictors were selected using leave-one-out cross-validation (LOO IC). Results: In males, CSA, age, leg side, …

The Exaggerated Blood Pressure Response To Activities Of Daily Living And Exercise Is Dependent Upon The Fitness Of People With Hypertension, Joseph D. Larsen
Theses and Dissertations
Purpose: Determine if the previously reported exaggerated systolic blood pressure response to daily activity and moderate exercise amongst hypertensive adults could be accounted for by differences in fitness. Methods: 30 normotensives adults (15 low fitness control (LFC) and 15 high fitness control (HFC)) and 15 unmedicated adults with ambulatory hypertension (HTN) participated in this study. Participants completed 24-hour ambulatory blood pressure monitoring (ABPM). Lactate Threshold (LT) and estimated ����̇O2max were determined for each participant. A week later, blood pressure was measured while participants completed 5-minute bouts of treadmill exercise at fixed absolute intensities (2.5 mph 0% and 12% grade) and …
Characterization Of Ultra-High-Speed Friction Stir Welds Made In Thin Sheet Aa6061-T4 Material, Todd Grant Lainhart
Characterization Of Ultra-High-Speed Friction Stir Welds Made In Thin Sheet Aa6061-T4 Material, Todd Grant Lainhart
Theses and Dissertations
Friction stir lap welding (FSLW) of thin aluminum sheets in industry and in research has faced challenges in weld quality that limit welding speeds. Interfacial defects such as hooking and thinning are common defects that appear at the interface of FSLW, and researchers and process operators have traditionally reduced process parameters such as feed rate and spindle rotation to fully eliminate the defects. While such measures are successful in creating fully consolidated FSLW, feed rates for FSLW have stagnated around 1 mpm with the fastest feed rates recorded at 3 mpm, making it difficult for manufacturers to implement FSLW in …
Computational Advances For Single-Cell Proteomics, Hannah Boekweg
Computational Advances For Single-Cell Proteomics, Hannah Boekweg
Theses and Dissertations
The overarching goal of biologists is to characterize biological systems. When the workings of a system are understood, they can be fixed, broken, preserved, mimicked, and even replicated. The field of proteomics seeks to characterize systems through the lens of proteins. Proteins are referred to as the 'workhorse' of the cell to illustrate that they perform most functional tasks within the cell. These tasks are highly varied, including enzymatic activity, structural support, transport, storage, cell signaling, gene regulation, immune response, and more. Proteomics has been instrumental in new biological discoveries by characterizing the functional state of cells. A new area …
The Cellular Mechanisms Of Alzheimer's Disease Protection By The Pilra G78r Variant, Wenhan Cheng
The Cellular Mechanisms Of Alzheimer's Disease Protection By The Pilra G78r Variant, Wenhan Cheng
Theses and Dissertations
Microglial dysfunction is increasingly linked to Alzheimer’s Disease (AD). Immune receptors like TREM2 and CD33 play opposing roles in microglial activity. TREM2 activation triggers immunoreceptor tyrosine-based activation motif (ITAM) signaling to promote microglial activities, including amyloid-β clearance, but variants in TREM2 such as R47H that impair its function increase AD risk. In contrast, CD33 is an inhibitory receptor that contains an immunoreceptor tyrosine-based inhibitory motif (ITIM) which transmits signals that suppress microglial function. An AD-protective variant in CD33 alters CD33 activity, potentially enhancing TREM2 function. PILRA is another inhibitory immune receptor expressed by microglia that contains an ITIM. A naturally …
Growing Pains: Relations Between Racial Discrimination And Body Esteem With Ethnic-Racial Identity By Pubertal Timing For Female Adolescents Of Color, Emily J. Takamasa
Growing Pains: Relations Between Racial Discrimination And Body Esteem With Ethnic-Racial Identity By Pubertal Timing For Female Adolescents Of Color, Emily J. Takamasa
Theses and Dissertations
Puberty is a near-universal experience among adolescents, and yet rarely have researchers considered the racialized contexts and salience it has, for girls of color. Using the phenomenological variant of ecological systems theory (PVEST), this study examines the relation between pubertal timing, body esteem, racial discrimination and ethnic racial identity (ERI) components (affirmation, exploration, resolution) among adolescent girls of color (n = 218, Mage = 15.7, U.S. sample). Results showed that higher body esteem predicted greater ERI exploration and resolution, particularly for girls with average or late pubertal timing. Additionally, racial discrimination was linked to higher ERI exploration and resolution only …
Quantum-Chemical Modeling Of Mechanisms And Selectivity In Open-Shell Organometallic Reactions, Michael T. Davenport
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 …
Rapid Beamformer Weight Calibration Update Method For The Advanced L-Band Phased Array Camera For Astronomy (Alpaca), Kayla Lyman Ward
Rapid Beamformer Weight Calibration Update Method For The Advanced L-Band Phased Array Camera For Astronomy (Alpaca), Kayla Lyman Ward
Theses and Dissertations
The Advanced L-Band Phased Array Camera for Astronomy (ALPACA) is a phased array feed instrument designed for the Green Bank Telescope. It is capable of producing 40 real-time beams on the sky, widening the telescope's field of view and significantly increasing survey speed. ALPACA employs an RF-over-fiber (RFoF) signal transport system from the phased array feed front end to the digital backend. This RFoF link is expected to introduce phase delays and changes in gain through out the course of an observation, invalidating the beamformer weights previously calculated. This work presents rapid beamformer weight calibration updates for ALPACA, a method …
