Over 96% of subjects were on 100-320 mg monthly (divided weekly or biweekly) at last follow-up. There was an overall increase in mean total and free testosterone (T) over the dose range (p …

Genomes For Kids: The Scope Of Pathogenic Mutations In Pediatric Cancer Revealed By Comprehensive Dna And Rna Sequencing, Scott Newman, Joy Nakitandwe, Chimene A Kesserwan, Elizabeth M Azzato, David A Wheeler, Michael Rusch, Sheila Shurtleff, Dale J Hedges, Kayla V Hamilton, Scott G Foy, Michael N Edmonson, Andrew Thrasher, Armita Bahrami, Brent A Orr, Jeffery M Klco, Jiali Gu, Lynn W Harrison, Lu Wang, Michael R Clay, Annastasia Ouma, Antonina Silkov, Yanling Liu, Zhaojie Zhang, Yu Liu, Samuel W Brady, Xin Zhou, Ti-Cheng Chang, Manjusha Pande, Eric Davis, Jared Becksfort, Aman Patel, Mark R Wilkinson, Delaram Rahbarinia, Manish Kubal, Jamie L Maciaszek, Victor Pastor, Jay Knight, Alexander M Gout, Jian Wang, Zhaohui Gu, Charles G Mullighan, Rose B Mcgee, Emily A Quinn, Regina Nuccio, Roya Mostafavi, Elsie L Gerhardt, Leslie M Taylor, Jessica M Valdez, Stacy J Hines-Dowell, Alberto S Pappo, Giles Robinson, Liza-Marie Johnson, Ching-Hon Pui, David W Ellison, James R Downing, Jinghui Zhang, Kim E Nichols

Pediatrics Research and Scholarship

Genomic studies of pediatric cancer have primarily focused on specific tumor types or high-risk disease. Here, we used a three-platform sequencing approach, including whole-genome sequencing (WGS), whole-exome sequencing (WES), and RNA sequencing (RNA-seq), to examine tumor and germline genomes from 309 prospectively identified children with newly diagnosed (85%) or relapsed/refractory (15%) cancers, unselected for tumor type. Eighty-six percent of patients harbored diagnostic (53%), prognostic (57%), therapeutically relevant (25%), and/or cancer-predisposing (18%) variants. Inclusion of WGS enabled detection of activating gene fusions and enhancer hijacks (36% and 8% of tumors, respectively), small intragenic deletions (15% of tumors), and mutational signatures revealing …

Doctoral Projects

The purpose of this DNP project was to create a tool to teach and evaluate student registered nurse anesthetists (SRNAs) at TheUniversity of Southern Mississippi (USM) on supraclavicular and femoral nerve blocks to promote safety in the clinical setting. An objective structured clinical evaluation (OSCE) for ultrasound-guided supraclavicular and femoral nerve blocks was created as the basis for this project. Best-practice techniques as identified by the AANA’s 14^thstandard of nurse anesthesia practice were researched and used in the development of the OSCE to promote a culture of safety for SRNAs and patients (AANA, 2019).

A culture of safety …

Airway Assessment And Bag-Mask Ventilation: An Objective Structured Clinical Examination, Kristen Berry, Leigh Allyson Brantley

Doctoral Projects

Airway assessment and bag-mask ventilation are critical components to the foundation of an anesthesia provider’s airway management. The SRNA may find difficulty in efficiently providing these skills when entering the clinical atmosphere, which could potentially lead to delayed patient care, adverse patient outcomes, and loss of confidence in the SRNA’s abilities. USM’s nurse anesthesia faculty recognized the need for an OSCE in airway assessment and BMV. The OSCE was developed and targeted at first-year SRNAs prior to entering clinical, with aims to increase competence, prevent delays in care, and prevent adverse patient outcomes.

The airway assessment and BMV OSCE was …

Best Practice Guideline: Color-Coded Syringe Labeling Of Anesthesia Induction Drugs, Lauren Elizabeth Pilgrim, Ashley Taylor Johnson

Doctoral Projects

The purpose of this Doctor of Nursing Practice (DNP) project was to propose a safe practice recommendation through the utilization of evidence-based research on the use of the standardized color-coded labeling guidelines for user-filled syringes in anesthesia practice. The primary objective of standardized color-coded labeling is to improve patient safety by facilitating the identification of user-prepared medication syringes. Guidelines developed by the American Society for Testing and Materials International (ASTM) are endorsed by the American Society of Anesthesiologists (ASA) and aim to increase quality care and patient safety. Currently, there is no standardized color-coded labeling system in anesthesia practice that …

Is Testing A Laughing Matter? Achievement Effects Via Working Memory And Humor Relevance, Ivan Jay Wayne

Dissertations

The relevant literature concerning the relationship between humorous intervention and academic performance features conflicting evidence. Authors present evidence that humor is able to directly benefit student academic performance (Ford et al., 2012), while other authors suggest humorous distraction may actually worsen performance (Bieg et al., 2015). Among the issues contributing to these contradictory findings are two particularly important considerations: the mechanism by which humor may impact performance and the content of humor used in interventions. One mechanism by which humor could impact subsequent academic performance is working memory (Strick et al., 2009). The first study (n = 31) investigated if …

Effects Of Creatine Supplementation Protocols And Doxorubicin On Cardiac And Skeletal Muscle Phosphocreatine System, Salaheddin M. A. Sharif

Dissertations

Doxorubicin (Dox) is a highly effective anticancer drug used to treat several cancer types; however, its use is limited due to its cytotoxicity (cardiotoxicity and myotoxicity). Doxorubicin-induced cardiotoxicity might occur within days and lead to congestive heart failure. Doxorubicin-induced myotoxicity involves fatigue, cachexia, and skeletal muscle dysfunction. Although the exact mechanisms causing Dox-induced cytotoxicity are not entirely understood, an alteration in the phosphocreatine system seems to be a central mechanism where studies showed Dox decreased phosphocreatine (PCr), creatine (Cr), impaired creatine kinase (CK) enzyme function, and decreased creatine transporter (CrT) expression in cultured cardiomyocytes. Ultimately, Dox-induced cytotoxicity might compromise quality …

Application Of Image Processing And Convolutional Neural Networks For Flood Image Classification And Semantic Segmentation, Jaku Rabinder Rakshit Pally

All Theses

Floods are among the most destructive natural hazards that affect millions of people across the world leading to severe loss of life and damage to property, critical infrastructure, and the environment. Deep learning algorithms are exceptionally valuable tools for collecting and analyzing the catastrophic readiness and countless actionable flood data. Convolutional neural networks (CNNs) are one form of deep learning algorithms widely used in computer vision which can be used to study flood images and assign learnable weights and biases to various objects in the image. Here, we leveraged and discussed how connected vision systems can be used to embed …

An Experimental And Computational Study Of 3-Dimensional Compact Windborne Debris Flight, Ta'jon Jordan

All Theses

In this thesis, the stochastic nature of 3-dimensional compact windborne debris flight is investigated experimentally and computationally. Previous literature (Holmes, 2004) analyzed the impact of strong winds on compact debris with applications to windborne debris flight. Baker (2007) derived the 2-dimensional equations of motion into a generalized dimensionless form that reveals the fundamental controlling parameters of compact debris flight. However, these models assume that compact debris is spherical, and the flight is, therefore, 2-dimensional. However most compact debris is not spherical, and its flight is 3-dimensional. Herein a previously developed model for free-falling compact windborne debris flight (Ahsanulllah et al., …

Psl-An Expert System To Evaluate Degree Plans, Robert Swanson

Computer Science & Engineering Student Projects

This paper describes a general-purpose expert system to evaluate degree plans according to the individual preferences of a college student. This system implements a preference specification language (PSL) on top of this expert system to allow for the textual expression of certain requirements and preferences that the system uses for evaluation. The PSL evaluator produces a single value to describe how well it meets the student’s preferences, which a plan generation system could use to create a degree plan optimized according to the specification.

Robo-Ump: A Study Of The Prospective Impact Of Automated Strike Zone Use In Major League Baseball Games From The Perspective Of Broadcasters And Media, Bob Greene

College of Journalism and Mass Communications: Theses

A qualitative analysis of the Major League Baseball industry’s perspective on the use of technology within the game, specifically the incorporation of an automated strike zone in place of traditional umpires, through targeted survey results from current MLB broadcasters and journalists or media members. Evidence from the research suggests that though those who are in favor of umpires being replaced by technology within the game, at least in some fashion, there are concerns that the technology in place is currently ready to provide the type of experience desired for MLB play when it comes ruling on balls and strikes with …

Moving Across Rural Spaces: A Content Analysis Of Contemporary Realistic Fiction Picturebooks With Rural Settings, Suzette Youngs, James A. Erekson, Christine Kyser

Reading Horizons: A Journal of Literacy and Language Arts

Romanticized rural storytelling creates difficulties for rural children in finding mirrors, seeing people like themselves and places like their homes as principal characters and settings in picturebooks. The same romanticism likewise makes it unlikely for picturebook readers in cities and suburbs to find realistic windows into rural life. Despite children’s book publishers’ purposeful increases in realistic representations of children across racial and cultural groups in recent decades, realistic and diverse narratives within rural spaces remain underrepresented, if not invisible. Drawing on critical rural theory (Fulkerson & Thomas, 2014; Williams, 1973) and tenets of nostalgia and the rural idyll (Boym, 2001, …

Video-Based Discussions About Literacy Pedagogy: Face-To-Face Versus Online Formats, Poonam Arya, Tanya Christ, Ming Ming Chiu

Reading Horizons: A Journal of Literacy and Language Arts

This study evaluated the similarities and differences in 50 preservice teachers’ (PTs’) literacy pedagogy learning outcomes when they engaged in videobased discussions that were both face-to-face (F2F) synchronous and online asynchronous. Across PTs’ response sheets, 396 idea units were collected and coded to identify their reports of learning about literacy pedagogy and application of this learning to their subsequent literacy instruction. Multivariate, multilevel, cross-classification logit regressions were used to compare outcomes across formats. Findings include that PTs reported learning similar total numbers of ideas across both video-based discussion formats but reported applying significantly more ideas from learning in the F2F …

The purpose of this study was to investigate upper elementary (Grades 4–6) and middle school (Grades 6–8) teachers’ views of grammar and its instruction and to determine differences in their views about grammar, its instruction, and its importance to writing proficiency. Participants in this online study were 196 practicing teachers in eight school districts in one western U.S. state. Two thirds of the teachers in the study taught at the elementary level, and one third taught at the middle school level. When asked what they taught when teaching grammar, the large majority of these teachers reported teaching parts of speech, …

Pedagogy Is Research: Investigating The Teacher-Researcher Identity And Pedagogy Of Teachers Who Completed An Action Research Project, Meagan Chelsea Brown Varona

Dissertations

This research study explored the development of a teacher-researcher identity and investigated the pedagogy of two teachers who completed an action research course. I sought to investigate the development of a teacher-researcher identity in connection to the utilization of critical responsiveness in order to address the stifling of teacher agency that has resulted from standardization and deprofessionalization of the teaching profession. Through braiding the theoretical frameworks of cultural-historical activity theory, pragmatism, and critical theory, I examined the development of a teacher-researcher identity and how it impacted the pedagogical judgments and decisions of teachers. This multiple case study required data collection …

Towards A More Comprehensive Understanding Of Wild Pig (Sus Scrofa) Impacts On Agricultural Producers: Insights From A Texas Case Study, Keith M. Carlisle, Nicole Didero, Sophie Mckee, Julie Elser, Stephanie A. Shwiff

United States Department of Agriculture Wildlife Services: Staff Publications

This research investigates the impacts of invasive wild pigs (Sus scrofa Linneaus) on agricultural producers in Texas, with the aim of identifying and describing all categories of wild pig impacts and quantifying the extent of producers’ over- or underestimation of their total wild pig-related costs in 2018, as compared to calculations based upon data subsequently provided by the producers about individual wild pig-related costs and losses. Based on interviews with 23 producers in 16 Texas counties, we identified more than 20 discrete categories of negative impacts and negligible positive impacts associated with wild pigs. Among them were categories that have …

Studies Of Avian Nasal Mites (Acari: Rhinonyssidae And Ereynetidae) And Their Interaction With The Brood Parasite Brown-Headed Cowbird (Molothrus Ater: Icteridae) And Phylogenetic Inferences Of The Genus Ptilonyssus (Rhinonyssidae) On Different Passerine Hosts Associated To Three States In The Us, Alexis D. Hilario Perez

Graduate Theses and Dissertations

Nasal mites are endoparasites that spend their entire life cycle inside the nasal cavities and respiratory passages of birds. The Brown-Headed cowbird (Molothrus ater) (BHCO) is an icterid bird that uses brood parasitism as a reproductive strategy in which it lays an egg in the nest of a different bird species and allows the host to raise its young. Interestingly, nasal mites reported from cowbirds represent the same species found infesting other icterids and other common host groups. In the first study, I examined how diversity and host prevalence might change in a large sample size of BHCO associated with …

Deep Learning Strategies For Pool Boiling Heat Flux Prediction Using Image Sequences, Connor Heo

Graduate Theses and Dissertations

The understanding of bubble dynamics during boiling is critical to the design of advanced heater surfaces to improve the boiling heat transfer. The stochastic bubble nucleation, growth, and coalescence processes have made it challenging to obtain mechanistic models that can predict boiling heat flux based on the bubble dynamics. Traditional boiling image analysis relies on the extraction of the dominant physical quantities from the images and is thus limited to the existing knowledge of these quantities. Recently, machine-learning-aided analysis has shown success in boiling crisis detection, heat flux prediction, real-time image analysis, etc., whereas most of the existing studies are …

An Investigation Of The Flexural Strength And Toughness Of Hybrid Plain And Fiber Reinforced Concrete For Pavement Applications, Wesley Keys

Graduate Theses and Dissertations

For decades, many solutions have been evaluated to combat cracking in concrete pavements. The study presented in this paper evaluates and compares the flexural performance under a third point loading configuration of plain concrete (PC) beams, fully fiber reinforced concrete (FRC) beams, and hybrid PC and FRC beams, with a top PC and bottom FRC layer. The purpose of this hybrid approach was to provide FRC in only half the section, saving cost, while providing a PC surface layer that is easier to finish. All PC top layers were applied at an age of 7-days, considered a reasonable time for …

Retrospective Analysis Of Impacts Of Highway Bypass And Widening Projects, Sanjeev Bhurtyal

Graduate Theses and Dissertations

Community members often worry that highway projects may have negative impacts on their local economies. This is typical for highway bypass and widening projects in small cities (population less than 50,000). It is a challenge for planners to balance public concerns of economic decline with desired project outcomes of mobility and safety. Much of this challenge stems from a lack of information on post-project outcomes related to economic and safety impacts of new construction projects. Thus, there is a need for an evidence-based framework to help planners with the decision-making process and better inform the community on potential outcomes. This …

Investigating Depth Estimation To Archaeological Magnetic Source Bodies, Jeremy G. Menzer

Graduate Theses and Dissertations

Magnetometry is the most widely applied archaeo-geophysical technique. Current practice standards employ the technique to map only in a two-dimensional plan view fashion, but in deep geologic studies depth estimators are routinely applied to magnetic datasets. These estimators provide three-dimensional information to magnetic source-bodies. There are many different depth estimators employed in geologic study that all require various degrees of processing complexity. This study investigates two mathematically simple techniques, half-width rules and multi-height methods. Half-width rules are likely the oldest depth estimators within the field while multi-height techniques are but a minor footnote in the literature. The applicability of these …
