Three Ethical Issues In Narrative Research Of Women Coaches’ Lifelong Learning, Bettina Callary

The Qualitative Report

It is important to reflect upon ethical issues in conducting narrative research beyond what may be considered in Research Ethics Board applications. Ethical issues were identified in a dissertation study that utilized a narrative research approach to explore the process of lifelong learning for five women coaches. Using journal reflections and participant and researcher conversations, three ethical issues are discussed. These issues arose during the process of collecting narratives from participants and in creating narrative analyses of the data. While there exists a broad range of views on narratives, all narrative researchers can benefit from reflecting on ethical issues within …

Modified Sodium Diuranate Process For The Recovery Of Uranium From Uranium Hexafluoride Transport Cylinder Wash Solution, Austin Dean Meredith

Theses and Dissertations

Uranium hexafluoride (UF₆) containment cylinders must be emptied and washed every five years in order to undergo recertification, according to ANSI standards. During the emptying of the UF₆ from the cylinders, a thin residue, or heel, of UF₆ is left behind. This heel must be removed in order for recertification to take place.

To remove it, the inside of the containment cylinder is washed with acid and the resulting solution generally contains three or four kilograms of uranium. Thus, before the liquid solution can be disposed of, the uranium must be separated. A modified sodium diuranate …

3d Finite Element Modeling Of Sliding Wear, Rodolfo G. Buentello Hernandez

Theses and Dissertations

This research focuses on the mechanical wear due to the sliding between two surfaces. Currently there is a need to identify and compare materials that would endure sliding wear under these severe conditions. The high costs of the high-speed sliding experiments has prevented the collection of the necessary data required to characterize wear. Simulating wear through Finite Elements (FE) would enable its prediction. This 3D wear model allows one to reasonably predict high-speed sliding mechanical wear. In the aerospace, automotive and weapon industries this model can aid in material selection, design and/or testing of systems subjected to high-speed sliding wear.

Multiplexed Fiber-Ring Laser Sensors For Ultrasonic Detection, Tongqing Liu, Lingling Hu, Ming Han

Department of Electrical and Computer Engineering: Faculty Publications

We propose and demonstrate a multiplexing method for ultrasonic sensors based on fiber Bragg gratings (FBGs) that are included inside the laser cavity of a fiber-ring laser. The multiplexing is achieved using add-drop filters to route the light signals, according to their wavelengths, into different optical paths, each of which contains a separate span of erbium-doped fiber (EDF) as the gain medium. Because a specific span of EDF only addresses a single wavelength channel, mode completion is avoided and the FBG ultrasonic sensors can be simultaneously demodulated. The proposed method is experimentally demonstrated using a two-channel system with two sensing …

A Dynamic, Broad Spectrum Approach To Covert Channels, Christopher Hoffman

Theses

In most covert channel systems, bandwidth is sacrificed for covertness. By using a dynamic, broad spectrum approach it was possible to use multiple covert channels to create a larger pipeline for data transmission. This approach utilized a monitor to determine how much data the network would be able to support before suspicion would be drawn to the change in traffic utility. The system then dispersed this traffic to each protocol proportionately using their monitored utility as a guide. A feedback channel was also utilized to determine if channel transmissions were successful and disabled any channels for future use that the …

Investigating Humor Within A Context Of Death And Tragedy: The Narratives Of Contrasting Realities, Brian D. Vivona

The Qualitative Report

Crime scene investigators (CSIs) are subjected to many complexities of working in a context of death, trauma and tragedy. They experience this context in a more intimate manner than any other member of the criminal justice community. Within these challenging work settings in which human lives have ended, humor can emerge as crime scene investigators attend to their tasks. The research question this study addressed is “How is humor used to negotiate work experiences and make meaning from working in a context that includes death, trauma and tragedy?” CSIs were interviewed and provided narratives from their lived experiences regarding humor …

Impacts Of Lateral Boundary Conditions On Regional Climate Projections Over West Africa, Jee Hee Kim

Master's Theses

Climate simulation and projections using regional climate models (RCMs) are sensitive to the choice of lateral boundary conditions (LBCs) which often are derived from global climate models (GCM). These LBCs used to drive RCMs describe the atmospheric conditions at the boundaries regarding atmospheric dynamics as well as atmospheric physics, including wind, atmospheric pressure, temperature and humidity. Understanding the impact of each component of LBCs is important for understanding and reducing the uncertainty in and improving the accuracy of RCM climate simulations and projections. In this study, the ICTP Regional Climate Model Version 4 (RegCM4) is used to investigate the impact …

Modeling Fecal Bacteria In Oregon Coastal Streams Using Spatially Explicit Watershed Characteristics, Paul Bryce Pettus

Dissertations and Theses

Pathogens, such as Escherichia coli and fecal coliforms, are causing the majority of water quality impairments in U.S., making up ~87% of this grouping's violations. Predicting and characterizing source, transport processes, and microbial survival rates is extremely challenging, due to the dynamic nature of each of these components. This research built upon current analytical methods that are used as exploratory tools to predict pathogen indicator counts across regional scales. Using a series of non-parametric methodologies, with spatially explicit predictors, 6657 samples from non-estuarine lotic streams were analyzed to make generalized predictions of regional water quality. 532 frequently sampled sites in …

Cleft Lip And Palate Repair: Bridging The Gap Between Genetics And Oral Health: An Individual Case Study, Duncan Perry

Honors Theses

Cleft Lip and Palate Syndrome (CL/P) is a condition that occurs in vitro, during fetal development. Because the majority of CL/P cases occur in underdeveloped nations, the families of CL/P patients are typically characterized by impoverished homes. These are the very people who cannot afford to pay for folic acid supplements, or reconstructive and reparative surgeries. Many families struggle under the extreme pressure of raising a child with CL/P. In these nations, the child often cannot receive the proper care they need, and usually are the product of unsuccessful surgeries. The stress of a CL/P patient is incredibly high, both …

Network Burst Monitoring And Detection Based On Fractal Dimension With Adaptive Time-Slot Monitoring Mechanism, Hsiao-Wen Tin, Shao-Wei Leu, Shun-Hsyung Chang, Gene Eu Jan

Journal of Marine Science and Technology–Taiwan

This study proposed an approach to measure the burstiness of network traffic based on fractal dimensions (FDs). By definition, burstiness is the degree of variation in network traffic. This study defined two types of FDs: (1) the FD of network traffic that describes the flow variation of network traffic, and (2) the FD of the range that describes the degree of flow dispersal. The proposed method uses an adaptive time-slot monitoring mechanism to monitor the network. The relevant FDs are derived from measurements obtained during each time slot in a monitoring window. This study conducted experiments using NS2 simulation data. …

Journal of Marine Science and Technology–Taiwan

The southern bluefin tuna (Thunnus maccoyii) is a longlived, large, and highly migratory marine fish in the Indian Ocean. They can live up to 40 years and migrate to the Great Australian Bight in the summer when 1-4 years old. The Great Australian Bight is characterized as the most productive coastal upwelling zone in southern Australia and is the largest area of cool-water carbonate sedimentation in the world. The barium (Ba) level is poor in the open ocean but rich in the upwelling area. This study used otolith Ba/Ca ratios as a natural tag to confirm that southern bluefin tuna …

The Legacy Of 1940: The Election Of Franklin D. Roosevelt To A Third Term, Kyle Lindsay

History & Classics Undergraduate Theses

For my honors history thesis, I examined the decision of Franklin D. Roosevelt to run for a third presidential term in 1940. This decision was an important one, for no other President in American history had been elected to a third term. My research indicated that despite his personal wishes, Roosevelt believed that he had to run again in 1940 to guide the United States during the uncertain period leading up to World War II.
