Improving Communication: Huddling For Change, Harnoor Chahal

Master's Theses

The purpose of this communication improvement project is to incorporate huddles between interdisciplinary departments within a microsystem in order to improve customer satisfaction by decreasing the number of grievances. Based on the increasing number of grievances due to delayed hospital discharge, which results from a lack of communication between team members, there is an increased need for communication between the microsystem. By implementing weekly huddles between the Inpatient and Outpatient nurses, not only will there be increased care-coordination, but there will also be a decreased delay in discharge from the hospital caused by missed or no communication. Evidence-based practice indicates …

Educational Prevention Program Of Surgical Site Infections At A Metropolitan Pediatric Hospital, Myra Hasan

Master's Theses

Surgical site infections (SSI) are a common cause of healthcare-associated infections (HAI). They remain a significant problem, as they are associated with increased morbidity and mortality and cause an increase in demand for several healthcare resources. In order to address this problem, hospitals have implemented several protocols and polices that are aimed to reduce these infections. However, the rates of SSIs continue to rise. Healthcare team members have found that while it is their responsibility to enforce preventative measures to the patient in the preoperative and surgical room, patient compliance to preventive measures at home also plays a role.

Inverse Dynamic Analysis Of Acl Reconstructed Knee Joint Biomechanics During Gait And Cycling Using Opensim, Megan V. Pottinger

Master's Theses

ACL (anterior cruciate ligament) injuries of the knee joint alter biomechanics and may cause abnormal loading conditions that place patients at a higher risk of developing osteoarthritis (OA). There are multiple types of ACL reconstruction (ACLR), but all types aim to restore anterior tibial translation and internal tibial rotation following surgery. Analyzing knee joint contact loads provide insight into the loading conditions following ACLR that may contribute to the long-term development of OA. Ten ACLR subjects, who underwent the same reconstruction, performed gait and cycling experiments while kinematic and kinetic data were collected. Inverse dynamic analyses were performed on processed …

A System For Conducting Laser-Induced Fluorescence Measurements On Gas Mixtures Exposed To Alpha Radiation, Patrick Ables

Master's Theses

This paper documents modifications to an existing vacuum system to allow laser-induced fluorescence spectroscopy measurements within simulated atmospheres under a variety of conditions. This added capability will expand the laboratory’s ability to experimentally validate a computational model that calculates the effects of radiation within the atmosphere. The computational model could reveal radiation-induced chemical products that can be used to develop an alternative detection method that can be implemented from a safe distance. The selection of molecules for experimental validation has been limited to those which can be detected utilizing cavity ringdown spectroscopy. The current model indicates nitric oxide and ozone …

Cornerstone Of Union Victory: Officer Partnerships In Joint Operations In The West, Aderian Partain

Master's Theses

The American Civil War included one of the pivotal naval contests of the nineteenth century. A topic of considerable importance is the joint operations on the western waters that brought about a string of crucial victories in the conflict for the Union. The effective cooperation of the naval river fleet and the western armies was a major cornerstone of Union victory. Scholars have written biographies of the more noted admirals and narratives of the flotilla have been detailed. What has not been accomplished is an exploration of the Union officers’ professional partnerships between the Mississippi Squadron commanders and their corresponding …

Coastal Wetland Dynamics Under Sea-Level Rise And Wetland Restoration In The Northern Gulf Of Mexico Using Bayesian Multilevel Models And A Web Tool, Tyler Hardy

Master's Theses

There is currently a lack of modeling framework to predict how relative sea-level rise (SLR), combined with restoration activities, affects landscapes of coastal wetlands with uncertainties accounted for at the entire northern Gulf of Mexico (NGOM). I developed such a modeling framework – Bayesian multi-level models to study the spatial pattern of wetland loss in the NGOM, driven by relative RSLR, vegetation productivity, tidal range, coastal slope, and wave height – all interacting with river-borne sediment availability, indicated by hydrological regimes. These interactions have not been comprehensively investigated before. I further modified this model to assess the efficacy of restoration …

Blazing Worlds, Bethany Kinney

Master's Theses

Blazing Worlds is a collection of short stories exploring themes of understanding, isolation, the world of work, and identity. These stories follow characters who are searching for connections to others, to their environments, to their work, and to themselves. The protagonists of these stories inhabit worlds that are slightly adjacent to reality, worlds cast into a near future, and worlds that operate by the logic of the campy and the fantastic. Through heightened technology, body horror, or blurred metaphysical boundaries, the residents of these blazing worlds pursue knowledge of their place in life and fight to establish and maintain their …

Personality, Technology, And Learning, Andrew Guydish

Master's Theses

Computers continued encroachment on today’s society can be seen in a college lecture hall, where a growing number of students use laptops for their academic needs. Current academic laptop use research predominantly makes broad generalizations across users, indicating that laptop use in the classroom has negative influences on academic outcomes. However, this research neglects to take into account possible individual differences in the users. It is hypothesized that students' levels of conscientiousness and impulsivity would moderate the relationship between laptop use and academic performance, while a student’s multitasking experience would mediate this same relationship, forming a moderated mediation model. Using …

Relationship Between Aerobic Capacity And Episodic Memory In Older Adults, Nicole Henderson

Master's Theses

The goal of this research was to examine the relationship between aerobic capacity and memory in older adults. Prior research demonstrated an age-related decline in episodic memory (memory for episodes and events), which may be partially due to a decreasing ability to engage in pattern separation – the ability to form new memories that are sufficiently distinct from prior memories. Studies in rodents suggested that aerobic exercise may improve pattern separation abilities in older animals, but similar research in humans is lacking. Here, I investigated whether individual differences on a memory test that taxes pattern separation were associated with differences …

An Interpretative Phenomenological Analysis Of 2013 Boston Marathoners' Experience Of Running A Subsequent Boston Marathon, Allison Grace

Master's Theses

While trauma experiences have been explored in several sport-related research studies, there is a lack of research on athletes’ experiences of a terror attack in sport. The present study qualitatively explored the meanings that 2013 Boston Marathoners ascribed to their experience of returning to the Boston Marathon to compete. Eight participants took part in semi-structured interviews. Interviews were analyzed via interpretative phenomenological analysis. Eight themes emerged and were organized temporally around pre-2013 Boston Marathon experience, 2013 Boston Marathon experience, and post-2013 Boston Marathon experience. Results suggest participants initially had difficulty processing their 2013 experience, but ultimately, several participants had a …

Structure And Emplacement Of The Eocene Golden Horn Batholith, North Cascades, Washington, Christopher Scudder

Master's Theses

The 48 Ma Golden Horn batholith is a ~310 km2, shallow intrusion constructed of sub-horizontal sheets in the crystalline core of the North Cascades of Washington. It is the only large body of granite in an orogen dominated by 96-45 Ma tonalite, and probably intruded during ridge subduction. The oldest and structurally highest unit of the batholith is diorite, followed by alkaline granite, one feldspar-biotite granite, two feldspar-biotite granite, and finally granodiorite, the youngest and structurally lowest unit. The batholith displays a weak NE-striking foliation restricted to the center of the intrusion and a stronger NW-striking foliation formed throughout the …

The Perceived Gayness Of Prep: The Influence Of Masculinity Ideology On Black Men Who Have Sex With Men's Interest In Prep, Ladectric Driver

Master's Theses

Black men who have sex with men (BMSM) experience higher HIV incidence rates than any other U.S. population subgroup. The development of a bio-behavioral strategy using anti-retroviral therapy, pre-exposure prophylaxis (PrEP), provides a new alternative for HIV prevention; however, interest and uptake among BMSM remains poor. Gender-based perceptions and roles may be a factor in PrEP interest among BMSM. The present study examined the relationship between avoidance of femininity, heterosexual self-presentation, PrEP stigma and PrEP interest among BMSM. A self-administered questionnaire assessing aspects of traditional masculinity ideology, stigmatized beliefs that PrEP use will out one as gay, and PrEP interest …

Observational Learning Of A Changing Goal Location In Rats, Ryan Troha

Master's Theses

Observational, or imitative, learning is a vital skill for survival. This type of social learning plays an important role in human development (e.g. Bandura), but is also relevant for other species.

We have developed an observational learning paradigm in which rats must learn the location of food in a T-shaped maze through observation. This is a working memory task with the correct goal changing on a daily basis. Therefore, the observer must attend to the demonstrator rat’s performance on a daily or continuous basis.

F344 rats can be trained to observe the location of food on a T-maze before being …

Selectivity Of The Lower Kellwasser Mass Extinction Event (Late Devonian) In The Appalachian Basin, Jaleigh Quai Pier

Master's Theses

Mass extinctions are often associated with multiple environmental perturbations. For example, the Upper and Lower Kellwasser Events (the two pulses of the Frasnian-Famennian mass extinction in the Late Devonian) coincide with both global cooling and ocean anoxia/dysoxia. Assessing the selectivity of extinction—which types of organisms survived versus died—can help constrain which environmental changes were most important as kill mechanisms. Here, selectivity is examined with respect to several factors during the Lower Kellwasser Event. A thick package of siliciclastic sediments was deposited in the Appalachian Foreland Basin during the Late Devonian. Thanks to recent stratigraphic revisions, the Kellwasser Events can be …

Funqual: User-Defined, Statically-Checked Call Graph Constraints In C++, Andrew P. Nelson

Master's Theses

Static analysis tools can aid programmers by reporting potential programming mistakes prior to the execution of a program. Funqual is a static analysis tool that reads C++17 code ``in the wild'' and checks that the function call graph follows a set of rules which can be defined by the user. This sort of analysis can help the programmer to avoid errors such as accidentally calling blocking functions in time-sensitive contexts or accidentally allocating memory in heap-sensitive environments. To accomplish this, we create a type system whereby functions can be given user-defined type qualifiers and where users can define their own …

Towards Autonomous Localization Of An Underwater Drone, Nathan Sfard

Master's Theses

Autonomous vehicle navigation is a complex and challenging task. Land and aerial vehicles often use highly accurate GPS sensors to localize themselves in their environments. These sensors are ineffective in underwater environments due to signal attenuation. Autonomous underwater vehicles utilize one or more of the following approaches for successful localization and navigation: inertial/dead-reckoning, acoustic signals, and geophysical data. This thesis examines autonomous localization in a simulated environment for an OpenROV Underwater Drone using a Kalman Filter. This filter performs state estimation for a dead reckoning system exhibiting an additive error in location measurements. We evaluate the accuracy of this Kalman …

Investigating Forward Flight Multirotor Wind Tunnel Testing In A 3-By 4-Foot Wind Tunnel, Reed Danis

Master's Theses

Investigation of complex multirotor aerodynamic phenomena via wind tunnel experimentation is becoming extremely important with the rapid progress in advanced distributed propulsion VTOL concepts. Much of this experimentation is being performed in large, highly advanced tunnels. However, the proliferation of this class of vehicles extends to small aircraft used by small businesses, universities, and hobbyists without ready access to this level of test facility. Therefore, there is a need to investigate whether multirotor vehicles can be adequately tested in smaller wind tunnel facilities. A test rig for a 2.82-pound quadcopter was developed to perform powered testing in the Cal Poly …

"For All Such, A Country Is Provided": Choctaw Removal, Slave Trading, And Law In Southwestern Mississippi, 1800–1841, Anthony Albey Soliman

Master's Theses

At the beginning of the nineteenth century there were few white settlers in the Mississippi Territory. Over the course of two decades, the United States used treaties to force the indigenous inhabitants, the Choctaw, out of this area by the United States to lands west of the Mississippi River. The United States’ goal in the region was to create a plantation economy in the Mississippi Valley based on the production of short-staple cotton sustained by enslaved African American labor. Focusing on the removal of the Choctaw and the subsequent installation of a plantation regime in the Mississippi Valley, this thesis …

Detection Method Of Subclinical Atherosclerosis Of The Carotid Artery With A Hemodynamics Modeling Approach, Marisa Peressini

Master's Theses

Subclinical atherosclerosis is an important area of research to evaluate stroke risk and predict localization of plaque. The current methods for detecting atherosclerosis risk are insufficient because it is based on The Framingham Risk Score and carotid intima media thickness, therefore an engineering detection model based on quantifiable data is needed. Laminar and turbulent flow, dictated by Reynolds number and relative roughness, was modeled through the carotid artery bifurcation to compare shear stress and shear rate. Computer-aided design and fluid flow software were used to model hemodynamics through the carotid artery. Data from the model was derived from governing equations …

Differential Power Analysis In-Practice For Hardware Implementations Of The Keccak Sponge Function, Nathaniel Graff

Master's Theses

The Keccak Sponge Function is the winner of the National Institute of Standards and Technology (NIST) competition to develop the Secure Hash Algorithm-3 Standard (SHA-3). Prior work has developed reference implementations of the algorithm and described the structures necessary to harden the algorithm against power analysis attacks which can weaken the cryptographic properties of the hash algorithm. This work demonstrates the architectural changes to the reference implementation necessary to achieve the theoretical side channel-resistant structures, compare their efficiency and performance characteristics after synthesis and place-and-route when implementing them on Field Programmable Gate Arrays (FPGAs), publish the resulting implementations under the …

Zinc Sunscreens Affect Development Of Strongylocentrotus Purpuratus Embryos, Brittany E. Cunningham, Nikki L. Adams

Master's Theses

The growing popularity of physical sunscreens will also lead to an increased release of the ingredients from zinc oxide (ZnO) sunscreens into marine environments. Though zinc (Zn) is a necessary micronutrient in the ocean, greater than natural Zn concentrations are being released into marine environments by use of sunscreens. The extent of the consequences of the addition of Zn to the ocean are not fully understood. We investigated effects of materials released by zinc oxide (ZnO) sunscreens on the development of California purple sea urchin, Strongylocentrotus purpuratus. Embryos developed in various concentrations of Zn, the sources of which included …
