Public Perceptions Regarding Surveillance Of Lyme Disease In Tennessee, Shaheena Yasmin Asad

Walden Dissertations and Doctoral Studies

Lyme disease (LD), a tick-borne illness, has been a growing concern in the state of Tennessee. Studies have established environmental concerns regarding a growing tick population and identified a gap between reported cases and disease burden in Tennessee. Despite this information, it remains classified as a low-incidence reporting state, raising concerns about underreporting that indicate an ineffective current surveillance system. Because the public perception regarding surveillance of LD is unknown, the purpose of this qualitative study was to explore how adults in Tennessee perceived LD as a credible public health threat within the context of the current surveillance system. Guided …

Consistent Phq-9 Administration At Mental Health Watch Initiation And Discharge In A Correctional Setting, Gouni Aicha Bouraima

Walden Dissertations and Doctoral Studies

This staff education project addressed inconsistent Patient Health Questionnaire-9 (PHQ-9) administration and documentation at mental health watch initiation and discharge in a correctional setting. A baseline audit showed 42.1% PHQ-9 documentation compliance (8 of 19 charts), below the 90% organizational benchmark, limiting objective depression severity data needed for clinical decision-making and safe transitions. The practice-focused question was: Among nurses working with incarcerated individuals at mental health watch initiation and discharge, what is the impact of staff education on nurses’ knowledge of PHQ-9 screening protocols? The purpose was to implement structured staff education to improve nurses’ knowledge of PHQ-9 trigger points, …

Staff Education To Improve Depression Screening And Management Using Phq-9, Elizabeth Aja

Walden Dissertations and Doctoral Studies

This doctoral project was a staff education initiative. It was motivated by the realization that depression is often under-recognized when standardized screening practices are not consistently implemented. The identified practice gap was inconsistent administration, interpretation, and documentation of the PHQ-9 by the nursing staff. The practice-focused question examined whether a staff education intervention would improve nurses’ knowledge and confidence in using the PHQ-9 for depression screening. The purpose of the project was to implement and evaluate an evidence-based educational program on PHQ-9 administration, scoring, interpretation, and documentation. Data analysis included descriptive statistics on pretest and posttest scores from 14 participating …

Implementation Of Visual Bed Indicator Lights To Improve Fall Prevention Processes, Andrea Leffew

Master's Projects and Capstones

Supporting Students’ Self-Efficacy And Motivation In The Mathematics Classroom, Audrie H. Cox

Masters Projects

This project examines the role of mathematics self-efficacy in supporting student motivation, engagement, and achievement in secondary mathematics classrooms. Through a review of current research, the project identifies instructional practices that strengthen students' confidence in their mathematical abilities, including formative assessments, meaningful feedback, supportive teacher-student relationships, and opportunities for productive struggle. Drawing on these findings, a professional development workshop session was developed to equip secondary mathematics teachers with practical, research-based strategies that promote positive mathematics self-efficacy and improve overall classroom instruction. By translating research into actionable teaching practices, this project aims to support more confident, motivated, and successful mathematics learners.

Evaluating Diagnostic Information Preservation In Weakly Supervised Medical Imaging, Vinceline Bertrand

Electronic Theses and Dissertations 2020 - Present

Weakly supervised medical imaging models trained with coarse image-level labels often report strong performance on metrics such as accuracy and AUC. This thesis argues that these metrics can be misleading: a model may succeed on a coarse diagnostic task while failing to preserve the fine-grained information needed for consequential clinical decisions. It makes this failure measurable through the diagnostic gap, defined as the divergence between coarse and fine-grained diagnostic preservation, across three connected studies. The first shows that near-perfect ovarian ultrasound accuracy reflects visual separability rather than pathological understanding. The second measures the diagnostic gap in a mammographic pipeline, where …

Decreasing Icu Clabsi Through Improved Central Line Dressing Integrity, Sharmila Reyes Moreno

Master's Projects and Capstones

Problem: Central line-associated bloodstream infections (CLABSIs) are a significant source of preventable patient harm, increased healthcare costs, and prolonged hospital stays. In a 20-bed medical-surgical ICU, CLABSI events increased from one case in 2024 to four cases in 2025, resulting in a standardized infection ratio (SIR) of 1.21, exceeding the organizational target of ≤ 0.87.

Context: Audits of central line dressings identified frequent edge lifting and dressing disruption despite staff awareness of CLABSI prevention practices. These findings suggested a gap between evidence-based recommendations and consistent clinical practice. The project was conducted in a 20-bed adult medical-surgical ICU serving a diverse …

Consumer Behavior In End-Of-Current-Use Electronics: A Multi-Method Approach To Improving Sustainability Outcomes, Payam Saeedi

Theses

The proliferation of network-connected consumer electronics has created a sustained challenge for sustainability and data security at the End-of-Current-Use (EoCU) stage. In the United States, devices accumulate in storage rather than entering reuse or recycling pathways, and a substantial share of devices change hands without proper data sanitization. This dissertation characterizes and quantifies consumer behavior at EoCU of consumer electronics in the U.S., with the goal of supporting the design of interventions that improve sustainability and data security outcomes. A survey of 4,000 U.S. respondents (3,747 after data cleaning) was developed and deployed across 10 categories of network-connected devices, capturing …

Experimental Material Analysis And Load Monitoring Of Polyurethane–Steel Belts Subjected To Static And Cyclic Dynamic Loading: Implications For Continuous Mooring Line Systems In Wave Energy Converters, Youssef Mohamed

Electronic Theses and Dissertations 2020 - Present

This study experimentally investigates the mechanical and viscoelastic behavior of a steel-cord-reinforced polyurethane synchronous belt capable of withstanding continuous cyclic loading as a potential compliant mooring element for WEC applications. Quasi-static and cyclic tensile tests were conducted to characterize the belt's mechanical response. The quasi-static determined that the belt behaved as a stiff, low-strain tensile member. Under approximately 100 kgf, the belt extended by about 0.107mm over a 250mm gauge length, apparent tensile modulus of 5.41GPa, an axial rigidity of 2.44MN, and an equivalent line stiffness of 9.75MN/m. Cyclic tensile testing showed high dynamic stiffness with stiffness-transfer ratio of 0.924. …

Drivers Of Stopover Distribution Across Two Autumn Migration Routes Of A Long-Distance Afro-Palearctic Migrant, The Common Cuckoo (Cuculus Canorus), Alex Gale, Máire Kirkland, Phil Atkinson, Robert Puschendorf, Chris Hewson

School of Biological and Marine Sciences

Across the globe, many long-distance migratory birds have undergone population declines. Understanding the environmental factors which underly migratory stopover locations can inform conservation strategies for such species. Here, we identify environmental predictors of autumn stopover sites used by UK-breeding male cuckoos (Cuculus canorus) migrating to centralAfrican wintering grounds via two alternative flyways. Between 2011 and 2021, 88 male cuckoos from UK breeding grounds were fitted with <5 g satellite tags connected to the Argos satellite-based tracking system. Filtered stopovers were used to build presence-pseudoabsence distribution models for each flyway, using Boosted Regression Tree and Random Forest algorithms with thirteen climatic, habitat, topographic and anthropogenic variables. Performance was evaluated using 10-fold cross-validation, and weighted ensembles were generated. To assess drought sensitivity, we produced predictions for high- and low-drought years based on Standardised Precipitation–Evapotranspiration Indices (SPEI). Models performed well (AUC=0.79–0.88; TSS=0.50– 0.66) and revealed route-specific environmental predictors. Along the western route, stopover probability was highest in cooler, semi-humid, high-elevation areas with low contemporaneous drought; Iberian mountain ranges emerged as key sites. Along the eastern route, stopover probability was greatest in heterogeneous habitat, with lowlands and uplands favoured over intermediate elevations; the Po watershed appears particularly important. Hunting risk (included to assess anthropogenic threat) was also high at key areas. The spatial extent of stopover regions—and the probability of them being utilised—declined during years ofhigh short-term drought along the western route, and high long-term drought along the eastern route. Whilst Iberian montane stopover regions are sensitive to increasing drought and aridity under climate change, their topographic heterogeneity may provide climatic refuge while limiting intensive land uses. Preference for heterogeneous habitat within the Po watershed highlightsthe need to retain semi-natural habitat within agricultural landscapes. We recommend route-specific conservation measures and higher resolution models using newly available GPS tags to better understand fine-scale site selection within the regions highlighted here.

Hydrothermal systems in volcanic calderas are critical in signalling volcanic unrest, forming ore deposits, and sustaining chemosynthetic microorganisms. Analysis of a ~3500-year sequence of sediments collected from the Santorini caldera, Greece, during International Ocean Discovery Program (IODP) Expedition 398 reveals the behaviour of a prolonged paleo-hydrothermal system. Sediment geochemical and metagenomic data record vigorous hydrothermal activity and metal fluxes for ~1100 years, within a 2270-year window between two major eruptions. Sediment hydrothermally-derived trace metals are significantly enriched over background (~200-fold for As and Hg, and 10–50-fold for Mn, Sb, Mo, and V), with long-term metal fluxes (9 t yr^{−1 …}

Archaeal Signal Peptide Prediction Through Integration Of Proteomics And Machine Learning, Anjali Kaur

Theses

Signal peptides are short N-terminal amino acid sequences that direct proteins through cellular secretion pathways and play an essential role in protein localization and function. Computational tools such as SignalP are widely used to predict signal peptides. However, prediction accuracy for archaeal proteins remains lower than for bacterial and eukaryotic proteins, likely because relatively few archaeal proteins were available for model training. The goal of this study was to determine whether expanding the archaeal training data used by SignalP 6.0 could improve archaeal signal peptide prediction. Archaeal proteomics datasets from five archaeal species were analyzed to identify proteins with experimentally …

Chronotivity: Concurrent And Prospective Influences On Creative Performance Among College Students, Hreem Mahadeshwar

Theses

Creativity is increasingly understood as a dynamic process influenced by biological, psychological, and contextual factors. Previous research has linked chronotype, sleep quality, affect, curiosity, and creative self-efficacy to creative performance; however, relatively little is known about how these factors jointly relate to creativity among college students or whether they predict creative performance over time. The present study examined concurrent and prospective relationships in undergraduate students at RIT (T1: n = 210; T2: n = 38), between these variables and creative performance using a two-timepoint design. Creative performance was assessed using the Alternative Uses Task and scored for creative quality and …

Assessing Gene Expression Changes In The Octocoral Briareum Asbestinum Due To Vibrio Coralliilyticus Exposure, Hailey Poignant

All HCAS Student Capstones, Theses, and Dissertations

Coral reefs are an essential ecosystem home to tons of marine diversity that humans have also  learned to rely on, but they are harmed by climate change and the increasing prevalence of disease. While most studies focus on reef-building coral, octocorals also warrant attention to reveal how they respond to similar stressors. Octocorals share distant ancestry with reef-building corals, so there may be overlap in their immune responses which could provide insight into future restoration projects. To understand how octocorals respond to disease, the octocoral Briareum asbestinum was used as a model to examine gene expression changes caused by the …

Hematological, Inflammatory, And Oxidative Stress Biomarker Profiles In Substance Abuse Combinations: A Comprehensive Evidence-Based Review, Teif Naif Freeh Alenezi, Samia Soliman Barghash

Saudi Toxicology Journal

A potential risk of polysubstance use in relation to substance abuse can involve the development of intricate pharmacological interactions affecting the immune system and oxidative stress responses of the body. The current review aims to present a synthesis of the existing literature about hematologic, inflammatory, and oxidative stress markers associated with three patterns of polysubstance use: (1) stimulants and cannabis, (2) stimulants/depressants and CNS depressants, and (3) multi-drug complex usage. This review explores markers such as a neutrophil-to-lymphocyte ratio (NLR), systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), eosinophil-to-lymphocyte ratio (ELR), total oxidant …

“Shh!” Bleaching As An Auto-Destructive Art Method Of Representing The Silencing Of Women, Kristelle Tenero De Leon

DLSU Arts Congress Conference Proceedings

This paper discusses the artistic representation of the muffling of women’s voices and the culture of silence through a theoretically auto-destructive method of artmaking—bleaching using mark-making on textile. Through studio art research, the reductive and erasing properties of bleaching agents are used by bleaching printed images of women in fabric to metaphorically represent and articulate the existence of silencing imposed upon women. Guided by the lens of feminism and Gustav Merger’s manifesto of auto-destructive art, this work presents the artistic images of 13 women across Philippine history—from the babaylans to Maria Ressa—on textile, imbued with bleaching effects. Moreover, the work …

Indigenous Pedagogies As An Arts-Based Framework For Education 4.0, Andylyn Simeon

DLSU Arts Congress Conference Proceedings

While Education 4.0 promises to cultivate 21st-century skills like creativity and critical thinking, the reality often falls short. Current frameworks are heavily technocentric, prioritizing digital tools and measurable data over the communal, emotional, and spiritual depth that true learning requires. This paper argues that we can restore balance to this digital shift by looking toward Indigenous Pedagogies (IPs). Far from being “obsolete” relics of the past, these are sophisticated, arts-based systems rooted in storytelling, ritual, and land-based creation that can offer a creative blueprint for the human-centered goals that Education 4.0 claims to value. Through a qualitative synthesis, I deconstruct …

Urinary Antimony As A Biomarker For Differentiating Heroin And Brown Mixture Use, Shu-Mei Tsai, Yu-Han Hsiao, Yan-Zin Chang, Sai-Wai Ho

Journal of Food and Drug Analysis

Heroin is classified as a Schedule I controlled substance with severe legal consequences for its use, whereas liquid Brown Mixture (BM) is a legally available and commonly prescribed cough remedy in Taiwan. However, numerous cases of BM ingestion have been misinterpreted as heroin use because BM contains opium tincture, leading to similar urine test results. Owing to the rapid metabolism of heroin, detection of the parent drug and its primary metabolite, 6-acetylmorphine, in urine is difficult; thus, interpretation often relies on morphine concentration and the morphine-to-codeine (M/C) ratio, which can be inconclusive. In our BM analysis, the M/C ratio was …

The Effect Of Spin Polarization On Ion-Acoustic Solitary Waves In Quantum Plasmas, Amirhosein Rezvani, Sedigheh Miraboutalebi, Leila Rajaei, Mahmoodreza Sharifian

Turkish Journal of Physics

The exchange interaction, a fundamentally quantum-mechanical phenomenon, can significantly modify the classical description of cold, overdense plasmas. These quantum effects can be systematically analyzed within the framework of quantum magnetohydrodynamic (QMHD) theory, which enables the use of separate momentum equations for spin-up and spin-down electron populations. In this study, we adopt this approach to incorporate exchange interactions for both spin species and investigate the excitation of ion-acoustic wave (IAW) solitons in the plasma system. Using a perturbative expansion method, the governing equations are reduced to a nonlinear Schrödinger equation (NLSE), which admits solitonic wave solutions. The stability of these solitons …

Properties Of Enjoyable Mathematical Contexts From The Student Perspective, Emilie Nadine Hendrickson

Theses and Dissertations

Researchers continue to grapple with how to meaningfully engage students in mathematical content. Many students report disengagement due to perceptions that mathematics is difficult, irrelevant, boring, or anxiety-inducing. This study sought to understand how students interpret and respond to different mathematical problem contexts, with particular attention to the reasons students describe certain problems as enjoyable or unenjoyable. Using semi-structured interviews, this research examined student responses to a variety of mathematical problem types primarily across affective engagement. Students reflected on specific problem contexts and explained which features supported or hindered their enjoyment and engagement. Students described that contexts were enjoyable have …

Rfsoc Based Ground Penetrating Radar For Detection And Avoidance Of Underground Utilities, Brady Bowerbank

Theses and Dissertations

Preexisting underground utilities present a considerable danger to underground boring projects. Gas and electrical lines can be damaged, leading to major economic impact and even loss of life. While maps of underground utilities exist, they are not always accurate and gas and electrical lines can shift over time, necessitating tools to accurately detect utilities so that crews can steer the machines away from any possible danger. In this thesis, the design of a new frequency-modulated continuous-wave (FMCW) ground penetrating radar (GPR) is outlined. The design of a lightweight, flexible radar is demonstrated using the CASPER FPGA framework with an operating …
