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 …

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 …

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 …

When asked what they taught when teaching grammar, the large majority of these teachers reported teaching parts of speech, …

Organizational Culture: An Examination Of The Role Of Leadership In Neutralizing The Negative Effects Of Technostress During Operational Shifts, David P. Kirkland

All-Inclusive List of Electronic Theses and Dissertations

COVID-19 created a support problem for public universities across the United States and required that IT departments and professionals alter how they performed in 2020, and perhaps beyond. IT professionals tasked with safeguarding large amounts of data were required to shift to a teleworking posture to continue offering a similar level of service as previously expected. In addition to the technological shift that organizations experienced because of COVID-19, leadership challenges also impacted IT departments across the United States. The rapid shift of operational duties has the propensity to increase technology-related stress, due to employee perception of being successful in their …

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 …

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

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 …

Examining Risks To Honey Bee Pollinators Foraging In Agricultural Landscapes, Jon Zawislak

Graduate Theses and Dissertations

Bee pollinators provide essential ecological services to wild plant communities, and addtremendous economic value to agriculture by improving both the quality and quantity of crop yield. Beekeepers are often contracted by growers to provide colonies of honey bees for pollination of high-value produce (fruits, vegetables and nuts). Many of the major commodity crops produced in the central and mid-southern United States are wind-pollinated (rice, corn, grain sorghum, wheat), or are sufficiently self-fertile (soybeans, cotton), and so do not require bee pollination in order to produce yield. Beekeepers still rely on these agricultural landscapes to support honey bee colonies when not …

Nonmetallic Jet Impingement Thermal Management For Power Electronics Via Additive Manufacturing, Reece Whitt

Graduate Theses and Dissertations

The increase in energy demanded by transportation and energy sectors has necessitated highly efficient thermal management for reliable power electronics operations. Conventional cooling techniques are limited by their inability to target switching location hot spot temperatures, leading to non-uniform thermal gradients. These devices, such as cold plates and heat sinks, also utilize heavy metallic structures that can accentuate electromagnetic interferences generated by high voltage switching processes. This work proposes a non-metallic jet impingement cooler for more customized thermal management, while simultaneously reducing the harmful effects of electromagnetic interferences. Additive manufacturing is utilized to enable jet impingement zones to target individual …

Combined Stressors In Reliability Failure Modes In Flip-Chip Electronic Packaging, Mahsa Montazeri

Graduate Theses and Dissertations

The trend toward miniaturization of electronic devices to fulfill Moore’s law introduces new reliability concerns to the electronic packaging process while worsening existing primary challenges. In solder interconnect specifically, temperature cycling is one of the prominent failure threats. However, with further downscaling of the flip-chip solder connections, electromigration also present a precarious failure mode in these interconnects. On the other hand, understanding the degradation mechanism in solders is crucial for the power electronic products' reliability considering the industrial tendency to replace wirebonds with solder attachment while improving the current carry capacity. This dissertation utilizes FEA simulation and an experimental approach …

Mission Profile Effects On Automotive Drivetrain Electronics Reliability: Modeling And Mitigation, Bakhtiyar Mohammad Nafis

Graduate Theses and Dissertations

The reliability of electronic devices is dependent upon the conditions to which they are subject. Temperature variations coupled with differences in thermal expansion between bonded materials results in thermomechanical stresses to build up, which can instigate failure in the interconnects or other critical regions. With the move towards electrification in the automotive industry, there is the increasingly important consideration of powertrain electronics reliability, the pertinent conditions being governed by the drive cycle or mission profile of the vehicle. The mission profile determines the power dissipated by the electronic devices, which determines the peak and mean temperature, temperature swing and the …
