Stewardship In Action: Reducing Unnecessary Antimicrobial Use In Long-Term Care, Mariatu Sulaiman

Walden Dissertations and Doctoral Studies

Antimicrobial overuse in long-term care facilities (LTCFs) contributes to antimicrobial resistance, avoidable healthcare costs, and adverse drug events, particularly when antibiotics are prescribed for asymptomatic bacteriuria rather than symptomatic urinary tract infections (UTIs). Evidence-based clinical practice guidelines, including the McGeer Criteria, provide standardized approaches for differentiating true UTIs from asymptomatic bacteriuria and supporting appropriate antimicrobial prescribing. The purpose of this evidence-based practice project was to evaluate the development and implementation of a clinical practice guideline incorporating the McGeer Criteria into an antibiotic stewardship program in an LTCF. The practice-focused question examined what evidence supports strategies for reducing unnecessary antimicrobial use …

Pre-Implementation Factors For Active Music Engagement (Ame): Barriers And Facilitators To Integrating An Evidence-Based Dyadic Intervention Into Pediatric Oncology Care., Kristin M. Story, Elizabeth Harman, Kristin Stegenga, Jelena Golubovic, Sheri L. Robb

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Pediatric cancer treatment is a difficult and distressing experience that often results in sustained, interrelated distress in young children and parents, and traumatic stress symptoms for some parents. Few evidence-based interventions address this dyadic distress. Active Music Engagement (AME) is a manualized, evidence-based music play intervention that significantly reduces distress in child/parent dyads and mitigates traumatic stress and improves well-being among highly distressed parents and those experiencing sociodemographic risk. Successfully integrating AME into standard care requires a systematic understanding of implementation factors. This study aimed to identify site-specific barriers and facilitators that influenced successful AME delivery during a recently …

Information systems as enablers have evolved from an efficiency and effectiveness focus to enterprise-wide performance, placing strong demands on information system leadership. Emerging leadership models call for collaborative practices. Information systems leadership in higher education is a challenging task. Universities' top management team members and their information system executive counterparts lack a common and shared vision and understanding of information systems capabilities and roles. As the highest-ranking officers in organizations, they make strategic IS decisions. Yet, noting that existing approaches are ineffective, there is a growing concern about the kind of leadership needed to guide the institutions. Four sets of …

Bcg Overexpressing Ag85b Reprograms Host Immune Response Through Coordinated Transcriptional Networks, Vivek Chauhan, Rakesh Kumar, Raja Veerapandian, Enrique I. Ramos, Chinnaswamy Jagannath, Shrikanth Gadad, Subramanian Dhandayuthapani

School of Medicine Publications

Antigen 85B (Ag85B), an immunodominant protein secreted by Mycobacterium tuberculosis (Mtb), induces robust T-cell-mediated immunity in host cells. Previous studies have demonstrated that recombinant BCG strains overexpressing Ag85B (BCG85B) confer significant protection against tuberculosis in mouse models. This study hypothesized that enhanced protection by recombinant BCG85B results from modulation of host immune gene expression by the Ag85B antigen. To test this, RNA-seq analysis was performed on splenocytes from mice immunized with the wild-type BCG (BCG-WT) and BCG85B strains. Differentially expressed genes (DEGs) in the splenocytes of BCG85B-immunized mice indicated upregulation of immune-related KEGG pathways, including Th1/Th2 and Th17 differentiation, NF-kappa …

"Tithing Is An Insurance Premium": A Framing Analysis Of Speaker Innovation And Diachronic Trends In Latter-Day Saint Religious Discourse, Reid Empey

Theses and Dissertations

Religious language relies on shared metaphor and frames that contextualize religious experience and practice. Current approaches to frame semantics (Fillmore 1982) and cognitive metaphor (Lakoff & Johnson 1980) lend important insight into religious language, particularly in describing the role that figurative language serves in a religious speech community. However, a vital component of many religious speech communities is the presence of and engagement with a scriptural canon, which often contains metaphorical and framing language that religious speakers can directly reference. Yet, past conceptualizations of speech communities have not accounted for this engagement with a shared canon. To illustrate the role …

Synthetic Strategies For Bioactive Peptides: From Aggregation Inhibitors To The Total Synthesis Of Tunicyclin C, Stephanie Graciela Garcia Morin

Theses and Dissertations

In Alzheimer's disease (AD), a brain protein called "tau" abnormally clumps and forms neurofibrillary tangles (NFTs), causing damage to brain cells. Ac-PHF6-NH2 is a hexapeptide segment of tau protein that plays a dominant role in tau aggregation and is used as a model to design tau protein aggregation inhibitors. In this research we synthesized four dehydroamino acid (□AA) containing PHF6 analogues with △Abu (derived from L-threonine) and △Val (derived from □-OH-Valine) at position 2 or 3 via dehydrations or azlactone ring-openings as key reactions. We evaluated their proteolytic resistance, ability to inhibit aggregation of PHF6, and impact on the morphology …

Standardizing Gestational Diabetes Mellitus Education To Improve Patient Knowledge And Care Consistency In A Prenatal Clinic Setting, Wynn Zara

Master's Projects and Capstones

The gestational diabetes mellitus (GDM) group visit framework aims to improve consistency of GDM education by standardizing referral processes, educational materials, staff workflows, and patient communication. Although evidence-based GDM education supports patient self-management and improved maternal-fetal outcomes, variability in education delivery contributed to inconsistent care within the outpatient maternal-fetal medicine setting. This quality improvement project was conducted in an outpatient maternal-fetal medicine clinic in Santa Clara County serving pregnant patients diagnosed with GDM. To address this gap, a standardized GDM group visit framework was developed and implemented using structured educational resources, referral criteria, and communication workflows. The intervention was evaluated …

Engineering Education Beyond The Engineering Classroom: Three Studies On Behavioral Nudges, General Education Completion, And Honors Program Participation, Andrew Harrison Volk

Theses and Dissertations

Engineering education extends well beyond the engineering classroom. Engineering undergraduates progress through general education courses, institutional support structures, and enrichment opportunities operating outside their major. The administrative offices that shape these non-engineering experiences typically operate independently of engineering departments, and the structural decisions they make can shape the engineering student's experience without engineering's input. This dissertation examines three settings in which decisions outside engineering matter for engineering students. Study 1 reports a PRISMA-format systematic review of nudge interventions in higher education, developing a four-category typology of nudge types (informational, environmental, process-oriented, and in-name-only) and a six-category typology of application domains. …

Thermomechanical Characterization And Modeling Of An Smp-Epoxy Composite For Deployable Space Structures, Ap Anshuman Behera

Theses and Dissertations

Deployable space structures can be stowed in a compact form and later allowed to their operational shape. Carbon fiber reinforced polymer (CFRP) composites have been utilized as a material candidate due to their increased strength-to-weight ratio and tailored performance. Current challenges associated with CFRP composites are driven by the viscoelastic nature of the polymer matrix causing long-term stowage effects and deployment issues such as shape deformation and incomplete recovery. In this study, a shape memory polymer (SMP) is presented as a potential option in mitigating these issues. An epoxy SMP is synthesized and experimentally characterized and its performance in the …

Ocean Salinity Effects On Lightning Frequency And Distribution In The Inner Core Of Tropical Cyclones In The Atlantic Basin, Desiree Knight

Theses and Dissertations

Different oceanic salinity profiles seen in the Atlantic have been found to influence tropical cyclone (TC) intensity. With the freshwater plume from the Amazon-Orinoco reaching into a TC development region during peak hurricane season, the stable ocean feature it creates has effects on SST, ocean mixing, enthalpy fluxes, and convection. This study investigates the relationship between sea surface salinity (SSS) and inner-core lightning of north Atlantic TCs and further explores the spatial variations of this relationship with TC intensity. SSS values are collocated with lightning flashes, which are split between “fresher” and “saltier” waters. Further investigations found that TCs have …

How Family Functioning Impacts Adolescent Outcomes: The Roles Of Cohesion, Flexibility, Communication, Satisfaction, And The Family Environment On Well-Being Across Levels Of Family Complexity, Emily E. Shaw

Theses and Dissertations

This dissertation research is a combination of two studies. The overarching and guiding focus for this study involved how family functioning and environments influence adolescent psychological well-being, and do these associations vary based on levels of family complexity. Study 1 examined family complexity and family environments as potential predictors of family functioning, while Study 2 examined family functioning and family complexity as potential predictors of adolescent negative (i.e., anxiety and depression) and positive (i.e., engagement, perseverance, optimism, connectedness, and happiness) well-being. In Study 1, family complexity was not predictive of family functioning, but the family environment was a strong predictor. …

Enhancing Levee Resilience With Biopolymers To Reduce Erosion And Improve Overtopping Performance, Ethan Tyler Vroman

Theses and Dissertations

Levee breaches from overtopping erosion present a significant flood risk across the US. Biopolymers have been proposed as a soil-stabilization method for embankments to improve slope stability and mitigate erosion. This study evaluates the technical and economic efficacy of two biopolymers, Rhizobium tropici (RT) and Xanthan gum (XG). Silt treated with 1% biopolymer was subjected to five wetting-drying cycles to assess erosion performance and durability. Laboratory testing revealed significant, temporary improvements to mechanical properties. Compared to untreated soil, RT and XG treatments increased critical shear stress by nearly one order of magnitude and more than an order of magnitude, respectively, …

Theses and Dissertations

Uncrewed aerial application systems (UAAS) are increasingly used for agricultural spraying, but spray deposition uniformity and effective swath width can vary between platforms. This study evaluated spray-pattern deposition and effective swath width for two commercial off-the-shelf (COTS) UAAS platforms during manual and autonomous flight operations. Manual, single-pass testing was used to assess preliminary performance and spray characteristics for both UAAS. Further autonomous multi-pass and single-pass evaluations were conducted to assess deposition uniformity and in-swath variability for both UAAS utilizing two methods of evaluation: Operation Self-regulating Application & Flight Efficiency (S.A.F.E.) pattern testing for manual flight evaluation and the Swath Gobbler …

A Study On The Welfare And Crop-Residue Ameliorating Potential Of Acheta Domesticus In The Context Of Insect Sequestration, Metabolism, And Excretion Of Three Mycotoxins: Aflatoxin B1, Deoxynivalenol, And Zearalenone, Ryan Thomas Paulk

Theses and Dissertations

Mycotoxins are a food security issue that affects all crops globally, but to varying degrees, due to the ubiquity of fungi that produce them. Developing new agricultural practices that can ameliorate lost nutrients post-contamination by removing mycotoxins for the next levels in the food chain can remedy an inevitable effluent in the circular economy. Farmed insects, such as the house cricket, Acheta domesticus, can potentially consume moldy, mycotoxin contaminated grains safely without transferring them to other trophic levels. The experiments herein test the biology of A. domesticus to consume three individual mycotoxins: aflatoxin B1, deoxynivalenol, and zearalenone. In addition to …

Toward Secure Genomic Intelligence: Privacy-Preserving Deep Learning Frameworks For Cancer Classification And Collaborative Analysis, Yibo Dong

Theses and Dissertations

Genomic data contains highly sensitive personal information, yet cancer classification and collaborative medical research increasingly depend on sharing such data across institutions. Existing privacy-preserving approaches for deep learning, including differential privacy (DP) and standard federated learning (FL), leave critical vulnerabilities: DP degrades model utility through noise injection, while FL relies on a trusted aggregation server that remains susceptible to gradient-based attacks. This dissertation develops, evaluates, and optimizes a series of privacy-preserving deep learning frameworks specifically designed for genomic cancer classification. First, a systematic benchmarking study evaluates DP, FL, and fully homomorphic encryption (FHE) across three deep learning architectures (fully connected …

The Fate Of Duplicate Meiotic Recombination Genes After Whole Genome Duplication In Vertebrate And Yeast Lineages, Sophie Maedo

Theses and Dissertations

Meiotic recombination is the exchange of DNA between homologous chromosomes that creates novel allele combinations and therefore aids in evolution. After whole genome duplications (WGD), challenges arise with proper chromosome segregation, necessitating changes to the meiotic recombination pathway. Reducing recombination rate and recombination gene copy number are mechanisms to correct multivalent formation. Within plants, copy number and retention rate of these genes has been well characterized; however, this is untrue for the wider eukaryote domain. Through this work, I show that meiotic recombination genes are maintained at a lower copy number than the rest of the genome; however, immediately after …

Impact Of In-Season Potassium Fertilizer Application On Sweetpotato Yields, Alyssa Lynn Hotchkiss

Theses and Dissertations

Sweetpotatoes require approximately three times more potassium (K) than nitrogen (N), making K the most applied nutrient in production. However, K fertilizer recommendations for sweetpotatoes in Mississippi remain outdated or are based on recommendations for other crops. This study evaluated the effects of K fertilizer rate, timing, and application method on sweetpotato production. Field trials were conducted during the 2023 and 2024 growing seasons at the Pontotoc Ridge-Flatwoods Branch Experiment Station in Pontotoc, Mississippi. Treatments included preplant K applications of 0, 134, or 191 kg ha⁻¹ K₂O, in-season sidedress applications of 56 kg ha⁻¹ K₂O, and four foliar K treatments. …
