Improving Employee Engagement Through Effective Change Management, Whitney Cearrow Sims

Walden Dissertations and Doctoral Studies

Human resources (HR) managers often face challenges due to ineffective change management strategies, which can lead to reduced employee engagement, decreased performance, and increased turnover. This issue is important to HR managers and organizational leaders who seek to improve workforce engagement and retention. Grounded in Kotter’s eight step change management model and Herzberg’s motivation-hygiene theory, the purpose of this qualitative pragmatic inquiry was to explore the strategies HR managers use to improve employee engagement. The participants were five HR managers from manufacturing companies in the southeast region in Georgia who had implemented effective change management strategies that improved employee engagement. …

First Quantitative Investigation On The Dosimetric Perturbation From Dental Hardware In Spot-Scanning Proton Arc (Sparc®) Therapy And Planning Strategies In Head Neck Cancer Patient Population, Evan Harbert

Masters Projects

Purpose

There has been a tremendous interest in applying Spot-scanning Proton Arc (SPArc^®) to benefit head and neck cancer (HNC) patient population. However, the dental hardware materials effects on the beam distribution are not well understood, and placing spots through the dental hardware may cause an unnecessary degradation of target coverage if the material components differ from the nominal plan. The purpose of this study is to provide a quantitative dose perturbation analysis of the uncertainties caused by dental hardware and introduce a SPArc^® planning strategy to mitigate such impacts.

Elucidation Of A Role In Biofilm Production For The Tyrosine Catabolism Pathway In Vibrio Cholerae And Analysis Of Reversible Phase Variation In Vibrio Vulnificus, Aheli S. Mukerji

LSU Doctoral Dissertations

Biofilms produced by the cholera pathogen Vibrio cholerae not only enhance its ability to survive in the environment but also allow pathogenic success of the bacterium. This organism also undergoes phase variation, switching between smooth and rugose colonial phenotypes, the latter forming much more vibrio polysaccharide (VPS) resulting in more robust biofilms and subsequently having an increased level of persistence. In a previous study, many genes were found to be upregulated in the transition from the smooth to the rugose phenotype. Here, several of these upregulated genes were investigated for their potential role in biofilm production, and an additional gene, …

Magnetic Field Enabled Assembly And Propulsion Of Colloidal Particles In A Magnetic Medium, Hashir M. Gauri

LSU Doctoral Dissertations

Colloidal particles are nano/micro meter-sized particles dispersed in a fluid medium and serve as diverse building blocks for assembling complex structures. The ease of tunability of the shape, size, and interparticle interactions of colloidal particles facilitates their assembly into rich structures and phases that mirror the assembly process of atomic systems. Often regarded as "big atoms" colloidal particles provide an ideal model system for investigating complex phenomena in condensed matter, such as crystallization and nucleation. While the assembly of colloids under thermodynamic equilibrium has been extensively studied, recent interest has shifted toward exploring colloids in non-equilibrium conditions to create dynamic …

Modulation Of Redox-Sensitive Cardiac Ion Channels, Rawan S. Orfali, Al Hassan Gamal El-Din, Varnika Karthik, Elisanjer Lamis, Vanna Xiao, Alena Ramanishka, Abdullah Alwatban, Osama Alkhamees, Ali Alaseem, Young-Woo Nam, Miao Zhang

Pharmacy Faculty Articles and Research

Redox regulation is crucial for the cardiac action potential, coordinating the sodium-driven depolarization, calcium-mediated plateau formation, and potassium-dependent repolarization processes required for proper heart function. Under physiological conditions, low-level reactive oxygen species (ROS), generated by mitochondria and membrane oxidases, adjust ion channel function and support excitation–contraction coupling. However, when ROS accumulate, they modify a variety of important channel proteins in cardiomyocytes, which commonly results in reducing potassium currents, enhancing sodium and calcium influx, and enhancing intracellular calcium release. These redox-driven alterations disrupt the cardiac rhythm, promote after-depolarizations, impair contractile force, and accelerate the development of heart diseases. Experimental models demonstrate …

The Role Of Self-Reported Health Ratings In Identifying Hospitalization Risk Among Older Adults: An Integrated Review And Secondary Analyses Of Medicare Claims Data, Mary B. Prybylo

MUSC Theses and Dissertations

Purpose: This study examined how Self-Reported Health (ratings), a person’s own evaluation of their overall health, relates to hospital admissions and emergency department utilization. It further assessed the extent to which demographic characteristics, Risk Adjustment Factor (RAF) scores (used to estimate healthcare expenditures based on clinical complexity), and the number of chronic conditions influence SRH rating and the likelihood of hospitalization.

Problem and Aim: The growing population of older adults places greater demands on healthcare services, leading to increased financial strain and a need for improved care strategies. Primary care teams, particularly those managing older adults, require effective assessment …

Metastable Macrocyclic Bis-Meisenheimer Adduct, Simon Pascal, Angélina Torres Ruiz, Aerin E. Baker, Douglas A. Vander Griend, Michel Giorgi, Aurélien Planchat,, Denis Jacquemin, Olivier Siri

University Faculty Publications and Creative Works

An electron‐deficient tetranitroazacalixarene is shown to undergo reversible cyanide capture via nucleophilic aromatic substitution, yielding an unprecedented class of metastable dianionic macrocycle incorporating two Meisenheimer units, fully characterized by single‐crystal X‐ray diffraction, NMR, and electronic absorption spectroscopies. Acting as a chemical fuel, cyanide transiently drives the formation of this adduct, which can spontaneously regenerate the parent macrocycle under mild conditions, representing a rare demonstration of metastability in a Meisenheimer complex. The dynamic behavior of this system, reminiscent of out‐of‐equilibrium assemblies, is finely tunable through macrocycle concentration, counterion nature, solvent, and temperature. Detailed crystallographic, spectroscopic, and computational analyses reveal that intramolecular …

Genome-Wide Characterization Of Vdac Gene Family In Soybean (Glycine Max L.) And In Silico Expression Profiling In Response To Drought And Salt Stress, Muhammad Muneeb Ullah, Muqadas Aleem, Mudassar Muhammad Iqbal, Ainong Shi

Horticulture Faculty Publications and Presentations

Soybean (Glycine max L.) is grown worldwide to obtain edible oil, livestock feed, and biodiesel. However, drought and salt stress are becoming serious challenges to global soybean cultivation as they retard the growth of soybean plants and cause significant yield losses. Voltage-dependent anion-selective channel (VDAC) proteins are well-known for their role in drought and salt tolerance in crop plants. In this study, we identified 111 putative VDAC genes randomly distributed in genomes of 14 plant species, including cultivated soybean (Glycine max) and wild soybean (Glycine soja). The comparative phylogenetic studies classified these genes into six different clades and found the …

Remote Sensing-Based Assessment Of Evapotranspiration Patterns In A Unesco World Heritage Site Under Increasing Water Competition, Maria C. Moyano, Monica Garcia, Luis Juana, Laura Recuero, Lucia Tornos, Joshua B. Fisher, Néstor Fernández, Alicia Palacias-Orueta

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

In water-scarce regions, natural ecosystems and agriculture increasingly compete for limited water resources, intensifying stress during periods of drought. To assess these competing demands, we applied a modified PT-JPL model that incorporates the thermal inertial approach as a substitute for relative humidity (RH) in estimating soil evaporation—a method that significantly outperforms the original PT-JPL formulation in Mediterranean semi-arid irrigated areas. This remote sensing framework enabled us to quantify spatial and temporal variations in water use across both natural and agricultural systems within the UNESCO World Heritage site of Doñana. Our analysis revealed an increasing evapotranspiration (ET) trend in intensified agricultural …

Under Pressure: Performance Loads And Recovery In Ncaa Division I Women’S Soccer During Fixture Congestion, Jade X. Dawson, Fabiano T. Amorim

Health, Exercise, and Sports Sciences ETDs

Soccer places high physiological demands on athletes, and match congestion—playing more than two games per week—is a growing concern at the NCAA Division I level. Limited recovery time between matches can impair performance and increase injury risk, prompting widespread use of recovery strategies. However, research on their effectiveness remains inconclusive, and most existing studies focus on male athletes, leaving a gap in evidence specific to female players. This review and observational study aim to evaluate non-nutritional recovery strategies in NCAA Division I women’s soccer and examine how recovery duration influences performance.

Match load data were collected from eleven female athletes …

By examining the pharmacology, pharmacokinetics, safety profile, and clinical indications of systemic CAIs, this review highlights strategies to mitigate treatment challenges, particularly in patients with comorbidities and complex medical backgrounds.

RECENT FINDINGS: New insights into the diverse roles and distribution of carbonic anhydrase (CA) isozymes have expanded our understanding of …

Mechanism Of Ph-Sensitive Amphiphilic Endosomal Escape Of Ionizable Lipid Nanoparticles For Cytosolic Nucleic Acid Delivery, Zheng Rong Lu, Da Sun

Faculty Scholarship

Lipid nanoparticles (LNPs) are among the most successful classes of nonviral delivery systems for nucleic acid-based therapeutics in treating human diseases. One of the key challenges in achieving efficient cytosolic delivery of nucleic acids is overcoming endosomal entrapment within cells. Conventional lipid bilayer-forming cationic and amino lipids mediate endosomal escape via the mechanism of lamellar-to-inverted hexagonal phase transition, resulting in suboptimal cytosolic cargo delivery. pH-sensitive amphiphilic cell membrane disruption and endosomal escape have emerged as a strategy for designing protonatable or ionizable lipids, especially nonlamellar lipids, for efficient cytosolic nucleic acid delivery. Nonlamellar amino lipids possess a large wedge-shaped tail …

Str Analysis Performance Comparison For Two Capillary Electrophoresis Instruments: The Seqstudio And The 3500 Genetic Analyzers, Yana Leichyk

Student Theses

This study compares the performance of two capillary electrophoresis instruments—the SeqStudio™ Genetic Analyzer and the 3500™ Genetic Analyzer—for forensic short tandem repeat (STR) analysis. Using the GlobalFiler STR kit and certified reference material (SRM 2391d), five key performance metrics were evaluated: sizing precision, signal reproducibility, detection sensitivity, mixture resolution, and overload tolerance. STR profiles were generated from single-source and mixture samples with DNA inputs ranging from 500 pg to 15.6 pg. Both instruments met the < 0.15 bp sizing precision requirement for forensic casework. Signal reproducibility tests showed that the SeqStudio often produced higher average RFU values, but with greater variability, while the 3500 demonstrated more stable signal performance across days and samples. Mixture detection was effective on both platforms up to 1:10 ratios. Dropout of minor alleles began to appear at 1:20 ratios, especially in green and yellow dye channels, on both instruments. Sensitivity studies confirmed full profile recovery down to 62.5 pg, with increasing allelic and locus dropout at lower inputs. Enhanced injection voltage (1.5 kV) did not improve low-template performance. In overload testing (1–5 ng input), the 3500 maintained a consistent signal output, while the SeqStudio exhibited signal suppression at 5 ng, likely due to internal normalization. The SeqStudio exhibited better spectral overlap compensation, with fewer occurrences of spectral bleed-through artifacts. These findings support the use of both platforms in forensic casework, while emphasizing the importance of platform-specific calibration and analytical threshold settings for optimal performance.

School of Dentistry Faculty Publications

Rubber dam isolation is crucial in providing sterility and a controlled environment when performing root canal therapy. Rubber dam clamps have been controversial due to their rigidity and composition, which is thought to cause damage to zirconia full coverage crowns. This study evaluated three types of zirconia crowns anterior 5Y, premolar 4Y, and molar 3Y to assess their resistance to damage from rubber dam clamps. Of the 30 total zirconia crowns that were tested for damage following the usage of rubber dam clamps, no fractures or chips were observed. There was no significant difference between the negative control group, and …

Distinct Echinocandin Responses Of Candida Albicans And Candida Auris Cell Walls Revealed By Solid-State Nmr, Malitha C. Dickwella Widanage, Kalpana Singh, Jizhou Li, Jayasubba Reddy Yarava, Faith J. Scott, Yifan Xu, Neil A.R. Gow, Frederic Mentink-Vigier, Ping Wang, Frederic Lamoth, Tuo Wang

School of Graduate Studies Faculty Publications

Invasive candidiasis affects 1.6 million people annually, with high mortality among immunocompromised and hospitalized patients. Echinocandins are frontline antifungals, but rising resistance limits their efficacy. Here, we show that Candida albicans and multidrug-resistant Candida auris share a conserved cell wall architecture yet differ markedly in their adaptive responses to echinocandins. Solid-state NMR reveals that both species possess a rigid inner layer of tightly associated chitin microfibrils and β−1,3-glucans, supported by a flexible matrix of β−1,6-glucans and additional β−1,3-glucans. Outer mannan fibrils rely on α−1,2-linked sidechains to maintain contact with the inner wall. In both species, caspofungin rigidifies β−1,6-glucans and mannan …
