Exploring Variability Of The Cg18562578 Methylquant Assay For The Forensic Discrimination Of Monozygotic Twins, Sydney E. Arnold

Student Theses

Monozygotic (MZ) twins possess identical DNA sequences, posing a problem for forensic scientists, as they are incapable of distinguishing MZ twins from each other using traditional DNA identification methods. However, the epigenomes of MZ twins will differ and might be used for their forensic discrimination. Here, we explored the variability of an assay previously developed by our laboratory that showed high discrimination potential for MZ twins using buccal swab DNA, cg18562578 MethylQuant. We measured precision at each step: bisulfite conversion, nested PCR, and qPCR, reproducibility, and repeatability. DNA methylation ratios were compared between two analysts carrying each step using the …

Development And Implementation Of An Ob/L&D Sbar Framework To Enhance Communication Between Obstetric Nurses And Anesthesia Providers: A Quality Improvement Initiative, Jenna E. Bigam, Laina J. Uzarski

Doctor of Nurse Anesthesia Practice (DNAP) Manuscripts

Effective communication between obstetric (OB) nurses and anesthesia providers is critical to ensure patient safety during epidural placements in labor and delivery (L&D) settings. At a large teaching hospital, communication gaps were identified when OB nurses requested anesthesia for epidural placements without consistently providing vital patient information. The lack of structured communication can result in important details being overlooked, which may lead to delays in care and potential patient harm. To address this, the SBAR (Situation, Background, Assessment, Recommendation) communication framework was implemented to standardize and improve information exchange. This Doctorate of Nurse Anesthesia Practice (DNAP) project aimed to enhance …

Exploring The Mediating Role Of Individual Performance In The Relationship Between Work-Life Balance And Attrition, Grace O. Leasure

Research Psychology Theses

Extensive research has established a relationship between work-life balance and employee attrition. However, limited attention has been given to the potential mediating role of individual performance within this dynamic. The present study aims to address this gap by examining whether individual performance mediates the relationship between work-life balance and attrition. It is hypothesized that higher work-life balance will be associated with lower attrition rates, partially explained by improved individual performance. Data will be collected via employee surveys and analyzed using mediation analysis. Anticipated results may provide organizations with a quantifiable, performance-based justification for investing in work-life balance initiatives.

Optimal Hypergraph Connectivity With Cut Queries, Hang Liao

Dartmouth College Ph.D Dissertations

Finding connected components in undirected hypergraphs—hypergraph connectivity—is a fundamental problem in computer science. It can be framed as a special case of Symmetric Submodular Function Minimization (SSFM), where the objective is to determine if the non-trivial minimizer is zero. This thesis develops an optimal algorithm for hypergraph connectivity within the $\CUT$ query model, where an algorithm probes a subset of vertices to learn the weight of the hyperedges ``cut" by that partition.

Our approach is constructive, culminating in an optimal algorithm for the general problem by first developing the necessary tools for two foundational subproblems. The main contributions of this …

Low-Dimensional Learning For Remaining Useful Life Prediction Of Batteries Operating Under Various Environments, Rodrigo Benavides

Theses and Dissertations

In reliability, we typically define the standard operating conditions under which a component operates. However, the differences in battery operating conditions cause variability in the degradation patterns of identically manufactured batteries, rendering remaining useful life prediction a major challenge. To aid this task, several sensors are utilized to monitor battery state-of-health. However, traditional prognostics algorithms do not scale well to the volume of data generated. Furthermore, several authors do not explicitly consider operating environments in their prediction models. Therefore, we present a high-dimensional data analytics framework that integrates operating environment information for battery prognostics. This framework combines Multilinear Principal Component …

Arginine Vasotocin And Corticosterone In Nesting And Non-Nesting Loggerhead Sea Turtles In X’Cacel-X’Cacelito Sanctuary, Krista Blair Reed

Theses and Dissertations

Sea turtles exhibit distinct behaviors before and after egg laying, however, not all individuals successfully oviposit. Some females display disruptions in their typical nesting behavior, returning to the water without laying eggs, which is referred to as a non-nesting emergence (NNE). NNEs can be due to external disturbances on the beach, but why they occur is often unclear. Arginine vasotocin (AVT) is a neuropeptide involved in various physiological processes, including stimulating smooth muscle contraction of the oviduct to facilitate egg deposition in nesting sea turtles. On the other hand, corticosterone is the primary stress hormone in sea turtles and is …
