Implementation Of A Ventilator-Associated Pneumonia Bundle To Reduce The Incidence Of Ventilator-Associated-Pneumonia And Improve Patient Care, Taylor Ryan Rice

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: Ventilator-associated pneumonia (VAP) is a concerning complication that can

develop from complications when a patient is placed on a mechanical ventilator. Endotracheal

intubation puts patients at risk for micro aspiration, which can lead to VAP.

Evidence Review: Nine articles were selected for review; after critical appraisal, seven were

kept for further review. Evidence in these articles shows that using evidence-based methods in a

VAP bundle can decrease the length of stay, mechanical ventilator days, and the incidence of

VAP.

Purpose: The purpose of this project was to improve oral care for intubated patients and keep

the incidence of VAP …

Optimization Of The Cmc Algorithm, Christopher Joseph Moner

Graduate Theses, Dissertations, and Problem Reports (ETD)

Cartridge cases recovered from discharged firearms contain tool marks produced by the internal mechanisms of said firearm. Firearm and tool mark examiners com pare these marks to determine whether two cartridge cases originated from the same firearm. Traditional comparison methods have been criticized for their subjective nature and reliance on examiner interpretation rather than objective decision thresholds. The Congruent Matching Cells (CMC) algorithm was developed as a quantitative, objective method for tool mark comparison. CMC is a surface topography correlation algorithm that partitions a tool mark into small regions, or cells, and evaluates their similarity using the areal cross-correlation function …

Studying The Mechanism For Ricin-Induced Growth Suppression, Daniel Judge

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study focuses on ribosome-inactivating proteins (RIPs), a class of potent toxins that includes ricin, α-sarcin, and shiga toxin, which irreversibly damage large subunit rRNA. Although the catalytic activity of ricin toxin A chain (RTA) is well characterized, the precise mechanisms linking ribosome damage to altered cellular morphology remain poorly understood. In this study, we engineered a tetracycline-regulatable expression system to express RTA in Saccharomyces cerevisiae. We characterized the effects of RTA expression on yeast growth, viability, and reproductive potential. We demonstrated that our expression system produced rapid and robust RTA expression and ribosome depurination within less than one …

New Fossil Mygalomorph Spiders (?Idiopidae, Pycnothelidae) From The Lower Cretaceous Crato Formation Of Brazil, Elis Maria Gomes Santana

Graduate Theses, Dissertations, and Problem Reports (ETD)

The infraorder Mygalomorphae represents one of the earliest-diverging lineages of spiders, but its fossil record remains sparse relative to the modern diversity of the group. This is a reflection of both ecological and preservational biases, such as the predominantly fossorial habits of many mygalomorphs and the strong bias of the spider fossil record toward amber deposits. Compression fossils from rock deposits are therefore especially important for documenting the evolutionary history of the group. Here, two new mygalomorph fossils from the Lower Cretaceous Crato Formation, Araripe Basin (Brazil) are described. The first specimen is tentatively referred to ?Idiopidae based on male …

Re-Evaluating Virtual Reality Manipulation Techniques For Precise Alignment Of Complex 3d Objects, Cherelle Connor, Alexander Giovannelli, Leonardo Pavanatto, Francielly Rodrigues, Haichao Miao, Vuthea Chheang, Brian Giera, Peer Timo Bremer, Doug A. Bowman

Faculty Research, Scholarly, and Creative Activity

Prior research has developed a number of manipulation techniques that can achieve precise object placement in virtual reality, but studies of these techniques typically use simple objects. We conducted a study comparing two existing techniques, (AMP-IT and WISDOM), during alignment of objects with complex geometry to evaluate the potential influence of geometric complexity on performance, usability, workload and preference. Our findings indicate that participants had faster completion times and higher trial completion rates with AMP-IT on high-precision alignment tasks, contrary to earlier findings that used simple objects. Yet WISDOM is still preferred and considered more usable, despite increased workload and …

The Lived Experience Of Special Education Director Retention: A Phenomenological Study Of Motivational And Organizational Influences, Matthew R. Taylor

Electronic Theses and Dissertations

The stability of leadership in special education is crucial for ensuring regulatory compliance, programmatic quality, and equitable services for students with disabilities. However, U.S. public schools face persistent challenges in retaining special education directors, resulting in a loss of institutional knowledge, service fragmentation, and increased risk of compliance failure. Drawing on self-determination theory and job embeddedness theory, this phenomenological study explored the intrinsic and extrinsic aspects that influence special education directors’ decisions to remain in their roles. Ten experienced special education directors from diverse public school settings in Texas participated in semistructured interviews and follow-up quantitative questionnaires. The analysis revealed …

Faculty Perceptions Of Engaging Generation Z Students Through Positive Education In The Classroom, Ashley D. Ragsdale

Electronic Theses and Dissertations

This qualitative study examined the engagement gap between Generation Z students and faculty in higher education, emphasizing how positive education approaches can help faculty become more confident and effective instructors. Generation Z students prefer instant internet access and digital learning, have shorter attention spans, and tend to be disengaged when instructors rely on traditional teaching methods. After the COVID-19 pandemic, this engagement gap became more evident. This basic qualitative study used semistructured interviews, reflexive journaling, and nonparticipatory observations. Participants included full-time health science faculty at a private university in central Texas. Each had at least 2 years of teaching experience …

Intersectionality In Discrimination, Posttraumatic Stress Symptoms, And Suicide Ideation: Black Americans In Appalachian Contexts, Jailyn May Wilson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Racial discrimination is recognized as a race-based traumatic stressor that has been associated with posttraumatic stress symptoms (PTSS) and suicide ideation (SI). However, there remains a paucity of research investigating the impact of racial and other forms of discrimination on understudied populations, including Black Americans residing in Appalachian regions. The current study used an online self-report survey to examine PTSS as a mediator in the association between perceived discrimination and SI and to examine the moderating effect of the number of identity factors with which one experienced discrimination (i.e., race, gender, region) on the relationship between perceived discrimination and PTSS. …

Geospatial Analysis Of Sinkhole Density And Characteristics In West Virginia, Marissa Shannon Loftus

Graduate Theses, Dissertations, and Problem Reports (ETD)

Creation of a sinkhole map of West Virginia provides useful data to help identify areas susceptible to sinkhole related hazards, as well as allowing for detailed analysis of factors controlling karst development. Newly available, statewide LiDAR-derived digital elevation data have made mapping sinkholes over larger spatial extents feasible. For this study, sinkholes were mapped for all areas of West Virginia that are underlain by carbonate rocks; then the distribution and characteristics were evaluated overall and in four focus areas (Berkeley and Jefferson counties, Pendleton County, Greenbrier County, and Monroe County). These areas correspond to broader physiographic regions, with Berkeley, Jefferson, …

An Empirical Framework For Evaluating Semantic Preservation Using Hugging Face, Nan Jia, Anita Raja, Raffi Khatchadourian

Publications and Research

As machine learning (ML) becomes an integral part of high-autonomy systems, it is critical to ensure the trustworthiness of learning-enabled software systems (LESS). Yet, the nondeterministic and run-time-defined semantics of ML complicate traditional software refactoring. We define semantic preservation in LESS as the property that optimizations of intelligent components do not alter the system's overall functional behavior. This paper introduces an empirical framework to evaluate semantic preservation in LESS by mining model evolution data from HuggingFace. We extract commit histories, $\textit{Model Cards}$, and performance metrics from a large number of models. To establish baselines, we conducted case studies in three …

Resilience For Whom? A Study In Pathways And Production Of Unequal Risk In The Rockaways, Aaryan M. Nair

Publications and Research

This paper investigates how climate adaptation policies in the Rockaway Peninsula of New York City produce unequal outcomes despite their ostensibly neutral design, framing resilience as an environmental and climate justice problem. Situated within a landscape marked by stark socioeconomic disparities, aging housing stock, and high exposure to coastal flooding, the study demonstrates that existing adaptation strategies—centered on uniform technical standards, insurance frameworks, and large-scale coastal infrastructure—systematically advantage actors with greater financial and institutional capacity while leaving low-income residents, particularly renters, disproportionately vulnerable.

The analysis identifies three core dynamics underlying this “unequal-by-design” resilience regime: (1) the stratified feasibility of compliance …

From Sentiment And Risk To Trade: A Country-Level Study On Geopolitical Trade Effects, Seung Heo

Publications and Research

Can geopolitical risk reshape international trade? I construct directed, monthly measures of bilateral geopolitical risk and its associated sentiment from approximately 5.1 million news articles in the GDELT Event Database, and estimate their effect on trade among eight Asia-Pacific economies at the HS2 product level over 2015--2025, using Poisson pseudo-maximum-likelihood gravity local projections with high-dimensional fixed effects. Pooled across countries, rising risk produces an immediate expansion of trade led by verbal threats and by news tone orthogonal to event content, rather than by material acts, indicating that how a conflict is reported can move trade before the conflict materializes. A …

The Seeds Of Peace And Justice, Shai Dothan

Chicago Journal of International Law

Some positive developments in international law had humble beginnings. They started from a small group of idealists who wanted to change the world for the better. Once their ideas gathered momentum, they got the support of people with power and transformed the world. State after state followed each other in a cascade toward improving international law. The purpose of this paper is to investigate the conditions that are beneficial for the initial germination of ideas with the potential to positively revolutionize international law. By using a series of case studies focused on the initiation of major transformations that improved international …

The Classical Limit In Geometric Quantization By Group Extension, Paul Bracken

School of Mathematical & Statistical Sciences Faculty Publications

Physical systems as a rule are associated with a symmetry group. The group approach to geometric quantization makes use of this to introduce a quantization by means of group extension. This procedure is discussed and applied to a physical system whose group law has its origin with the Galilean group. The main intention is to investigate the classical limit and its relationship under this approach to geometric quantization. The classical quantization conditions are obtained based on a deeper foundation.

Professionalism In Practice: A Novel Approach To Integrating Small Doses Of Case-Based Professionalism Education Into Monthly Grand Rounds., Allison H Taylor, Andrew Caruso, Kelley Arredondo, Ellen M Friedman, Stacey R Rose

Faculty, Staff and Students Publications

Introduction: Professionalism is a critical construct across the health professions, though learners and faculty report feeling underprepared to navigate difficult situations; education in professionalism is challenged by the absence of a universal definition, time constraints due to overcrowded curricula, and the lack of consistent messaging to learners and faculty.

Methods: Professionalism in Practice (PiP) was developed to provide small doses (∼5 minutes) of case-based professionalism education as part of an existing educational forum (Grand Rounds) to optimize attendance of both learners and faculty. Each vignette highlighted a common professionalism challenge and was aligned with an AAMC professional competency. Sessions were …

Functional Analysis Of Genes Enriched In Male Reproductive Organs: Validation Via Fertility Assessment Of 14 Knockout Mouse Lines, Kazumasa Takemoto, Katarzyna Kent, Kaori Nozawa, Shingo Tonai, Ahn H Pham, Terumi Fujimoto, Thomas X Garcia, Martin M Matzuk, Masahito Ikawa, Keizo Tokuhiro

Faculty, Staff and Students Publications

Tissue-restricted gene expression serves as a key indicator of functional importance within specific organs. Despite advances in high-throughput sequencing and genome editing over the past decade, this principle remains the gold standard for identifying candidate genes for functional studies. In reproductive biology, testis-restricted expression is anticipated to indicate genes crucial for gametogenesis, given the conserved features shared between spermatogenesis and oogenesis. Concurrently, rapid evolution of spermatogenesis-related genes is well documented and thought to arise through duplication and subsequent mutation of ubiquitously expressed genes. In this study, we established 14 knockout (KO) mouse lines for male reproductive organ-enriched genes, all of …

Public Art’S Role In Urban Transformation In New York City: 5 Pointz And The High Line, Shelby Stanton

Ai-Resistant Activities For Online And Large Enrollment Courses, Jason Bock, Eric Lemley

2026 Scholarly Teaching Conference: Concurrent Session Papers

The rapid adoption of generative AI tools has fundamentally challenged traditional assessments in higher education, particularly in large-enrollment and fully asynchronous online courses where instructor presence and grading time are constrained. While many instructors have responded by restricting AI use or adopting detection tools, research increasingly shows that detection-based approaches are unreliable and labor-intensive. We propose a design-centered alternative: reshaping assessments so that AI use becomes insufficient, rather than prohibited.

Drawing on a systematic process of testing proposed and original assessment ideas directly against multiple generative AI models (using both simple and advanced prompting strategies), we present a curated playbook …
