Spatializing The Soil-Ecological Factorial: Data Driven Integrated Land Management Tools, Travis Nauman
Spatializing The Soil-Ecological Factorial: Data Driven Integrated Land Management Tools, Travis Nauman
Graduate Theses, Dissertations, and Problem Reports (ETD)
Soils form the dynamic interface of many processes key to the function of terrestrial ecosystems. Many soil properties both influence and are influenced by activity of flora and fauna. Interactions between soils, biota, and climate determine the potential ecosystem services that a given unique ecological site (ES) can support, and how resilient a site is to various pressures and disturbances. Soil data are needed to fully understand how these factors interact, but because this data is difficult to obtain, existing soil maps are sometimes not detailed enough to fully explore relationships. Environmental raster GIS data layers were used to increase …

Old War, New Deal: Commemorative Landscapes, The National Park Service, And The 75th Anniversary Of The Civil War, Rebekah N. Oakes
Old War, New Deal: Commemorative Landscapes, The National Park Service, And The 75th Anniversary Of The Civil War, Rebekah N. Oakes
Graduate Theses, Dissertations, and Problem Reports (ETD)
The 75th Anniversary of the American Civil War was both the last major anniversary influenced by living Civil War veterans, and the first commemoration to occur with a number of key Civil War battlefields under the administrative control of the National Park Service. Although largely overlooked by historians, remembrance of the Civil War in the 1930s represented a key transition from commemoration primarily for the veterans of the conflict to a wider commemoration, finding from the Civil War a usable past and a landscape of national memorialization. Through this process, administrative and interpretive shifts changed the very purpose of Civil …
Sports Investment, Beliefs About Food-Related Behaviors, And Engagement In Problematic Eating Behaviors During Adolescence, Kaitlyn A. Ferris
Sports Investment, Beliefs About Food-Related Behaviors, And Engagement In Problematic Eating Behaviors During Adolescence, Kaitlyn A. Ferris
Graduate Theses, Dissertations, and Problem Reports (ETD)
Involvement in sport is the most widely reported organized activity among children and adolescents. To date, organized sports also represent the only organized activity examined in conjunction with youths' eating behaviors. Organized sports serve as contexts where messages about healthy eating and body image are communicated, and adolescents' beliefs about food and their bodies' degree of thinness and muscularity has the potential to be amplified in such settings as youth strive to perform at high levels during athletic competitions. However, inconsistency in the measurement of both organized sports participation and adolescents' engagement in problematic under- and over-eating behaviors has resulted …

Nondestructive Evaluation Of Corrosion In Reinforced Concrete Structures With Or Without Frp Wraps, Jonas Kavi
Graduate Theses, Dissertations, and Problem Reports (ETD)
Reinforced concrete is one of the most widely used construction materials for infrastructure applications across the world due to its reasonable durability and competitive cost. One of the major concerns with reinforced concrete is the deterioration caused by premature corrosion of embedded steel reinforcement under the influence of moisture, chlorides, and oxygen in the field environment. Fiber Reinforced Polymer (FRP), a material with many engineering properties better than concrete and steel, is increasingly being used in the rehabilitation of aging infrastructure and the construction of new ones.;The need for maintenance and repair of bridges, buildings and other infrastructure for their …
Estimation Of Changes In Breech Face And Firing Pin Marks Over Consecutive Discharges And Its Impact On 2d Correlation Systems, Justin Kirk
Graduate Theses, Dissertations, and Problem Reports (ETD)
When a firearm is discharged, the individual marks of that firearm's breech face and firing pin are imprinted onto the head of the cartridge case. The pattern of these individual marks is reproducible between test fires; however, over a large number of consecutive test fires, it has been observed that minute changes in these individual marks occur. These changes in individual marks have been shown to not affect an examiner in their ability to find an Identification or an Elimination, however, the effect that these changes have on Integrated Ballistic Identification System (IBISRTM) is largely unknown. If these changes in …

Graduate Theses, Dissertations, and Problem Reports (ETD)
A DNA aptamer against atrazine, a small molecule target, was computationally predicted using mfold and RNA fold to generate secondary structure from sequence, and NAB and RNA Composer to subsequently generate tertiary structure, subsequently relaxed, and the most-representative structures docked (AutoDock) with atrazine and simazine. According to analysis with X3DNA, the best predicted structure had the majority of its base-pairing sugars in the 2'-endo conformation, contained multiple helical regions in the B-form. Constrained docking revealed no preference for the target molecule (atrazine) over a negative target (simaxine), in contrast to in vitro binding results, thus more calculations are needed to …

A semi-structured interview was used to survey help-seeking attitude via questions about spirituality, therapy, and the connections between the two. Interpretative Phenomenological Analysis (IPA) was used to provide a framework for understanding how these factors potentially effect professional help-seeking attitudes in Black women and the role spirituality plays in developing help-seeking attitudes and the potential effect on professional psychological help. Ten interviews were conducted with Black women who lived or went to church in Akron, Ohio. Data from nine study participants were used and seven super-ordinate themes were found. The themes identified were as follows: 1) awareness and access; 2) …
Variations In Selenium Concentrations By Photochemical And Temperature-Controlled Iron Cycles, Kendi L. Waltemyer
Variations In Selenium Concentrations By Photochemical And Temperature-Controlled Iron Cycles, Kendi L. Waltemyer
Graduate Theses, Dissertations, and Problem Reports (ETD)
Selenium (Se) concentrations in natural waters may vary over a 24-hour (diel) period in response to temperature changes. Diel cycles of Se have not been reported in coal mine drainage (CMD) waters, and understanding the mechanisms of Se concentration variations in CMD is important for predicting Se fate and mobility. Iron (Fe) is often associated with CMD, and diel cycles of dissolved Fe species concentrations and/or the formation of Fe oxyhydroxide minerals may impact Se mobility. Experiments were conducted in a laboratory setting between July 2014 and April 2015 to determine if selenite (SeIV) concentration changes could be detected in …
Fine-Particle Charging-Rate-Limit Modification To Grain Dynamics In Abrupt And Gradual Inhomogeneities, Jeffrey J. Walker
Fine-Particle Charging-Rate-Limit Modification To Grain Dynamics In Abrupt And Gradual Inhomogeneities, Jeffrey J. Walker
Graduate Theses, Dissertations, and Problem Reports (ETD)
Gyro-phase drift is a guiding center drift that is directly dependent on the charging rate limit of dust grains. The effect of introducing a gyro-phase-dependence on the grain charge leads to two orthogonal components of guiding-center drift. One component, referred to here as grad-q drift results from the time-varying, gyro-phase angle dependent, in-situ-equilibrium grain charge, assuming that the grain charging is instantaneous. For this component, the grain is assumed to be always in its in-situ-equilibrium charge state and this state gyro-synchronously varies with respect to the grain's average charge state. The other component, referred to here as the gyro-phase drift, …

Lithofacies And Sequence Stratigraphy Of The Middle Devonian Marcellus Formation For A Cored Well In Clearfield County, Pennsylvania Using Core Analysis Methods, Chloe S. Wonnell
Graduate Theses, Dissertations, and Problem Reports (ETD)
Seven lithofacies were identified from visual descriptions and quantitative interpretations using traditional core analysis methods, such as core and thin-section description, x-ray diffraction (XRD), total organic carbon (TOC), and spectral core gamma-ray (GR). Ingrain's digital rock physics (DRP) color-coded CoreHDRTM lithofacies classification was successful at illustrating small-scale variations in the core based off high resolution bulk density (RHOB) and photoelectric factor (PEF) logs. A core-scale lithofacies log and spectral core GR aids in recognizing condensed sections and stacking patterns, which helps establish a sequence stratigraphic framework for the cored well that consists of six stratigraphic intervals. The sequence stratigraphic framework …

Graduate Theses, Dissertations, and Problem Reports (ETD)
The use of a spray-pyrolysis method is studied for the continuous synthesis of refractory oxide reforming catalyst for the conversion of hydrocarbon fuels to H2 and CO at 900°C. Nickel- and rhodium-doped zirconate pyrochlore materials with the formulas La1.89Ni2.81Y 0.25Ca0.11Zr1.47 and La1.89Rh 1.09Y0.25Ca0.11Zr1.641 were synthesized using the spray pyrolysis method. Both Pechini and glycine-nitrate precursor solutions were used in order to control the particle morphology, crystallinity, and surface area of the catalyst powder. Samples synthesized by the Pechini solution required post-synthesis heat treatment to 1000 °C for 2 hours to form the fully-crystalline pyrochlore phase. Both the Ni- and Rh-doped …
Emotion Regulation Flexibility And Illicit Substance Use Among Adolescents, Chit Yuen Yi
Emotion Regulation Flexibility And Illicit Substance Use Among Adolescents, Chit Yuen Yi
Graduate Theses, Dissertations, and Problem Reports (ETD)
The purpose of the present study was to investigate how emotion regulation (ER) flexibility was related to illicit substance use among adolescents. The hypotheses were that higher levels of ER flexibility (indicated by higher levels of context sensitivity, a larger ER repertoire, and higher levels of responsiveness to feedback about ER) would be associated with lower levels of substance use, fewer substance-related problems, and lower tendency to use substances in emotion-laden situations. In an online survey, adolescent participants (aged 18 - 20; M = 19.00; SD = 0.74; 77.1% female) answered questions about emotion regulation, illicit substance involvement and other …
Avoidance Of Token-Loss By Pigeons, James E. Cook
Avoidance Of Token-Loss By Pigeons, James E. Cook
Graduate Theses, Dissertations, and Problem Reports (ETD)
The response-dependent delivery and removal of tokens can reinforce and punish the responding of humans and nonhuman animals. The responding of humans can be maintained by the avoidance of token-losses, but this has not been demonstrated with nonhuman animals. Across three experiments, it was demonstrated that the responding of pigeons could be maintained in a token-loss avoidance arrangement. Tokens were delivered response-independently at the beginning of a token-loss avoidance period. Tokens were scheduled to be removed on a variable-cycle schedule. Responding canceled scheduled token-losses. Those tokens that remained were exchangeable for food during programmed exchange periods. Several parameters of the …

Assessment Of Professional Behavior In Students: Thoughts And Opinions Of Occupational Therapy Faculty, Diana R. Davis
Graduate Theses, Dissertations, and Problem Reports (ETD)
Professionalism and professional behavior of students has been a growing concern in the health professions for the past two decades (Aguilar et al., 2013; Davis, 2009; Swick, 2000). As a result multiple professions have identified core values and the professional behaviors that are a reflection of these in practice; and have begun to integrate assessment of student professional behaviors into educational standards. Occupational therapy has a history of publication dating back to 1995 regarding assessment of the professional behaviors of students but no profession wide expectations have been established.;This study attempted to describe the thoughts and opinions of faculty in …
Collecting Subjectsobjects: The Museum And Victorian Literature 1830-1914, Kayla Kreuger Mckinney
Collecting Subjectsobjects: The Museum And Victorian Literature 1830-1914, Kayla Kreuger Mckinney
Graduate Theses, Dissertations, and Problem Reports (ETD)
This study argues that the museum wielded enough cultural capital to shape not only the content of literature (which picked up themes like collection, hoarding, display, and organization) but also the formal arrangement of such literature into catalogues, taxonomies, and the dense material-based descriptions for which the Victorian novel is often criticized. The museum, it is shown, is far more central to Victorian thought than has been recognized, and its presence in literature has been misread or overlooked in contemporary criticism. This study also provides a narrative of the Victorian preoccupation with the museual, especially as regards the natural history …
Russian Soft Power Cultivation In The United States Of America: A Media Content Analysis Of "Russia Beyond The Headlines", David Evans
Graduate Theses, Dissertations, and Problem Reports (ETD)
The relationship between Russia and the United States of America has been a dominant feature of the international relations landscape for much of the last century. Following the collapse of the Soviet Union, this relationship has been significantly altered. Over the last decade, a resurgent Russia has begun to exert its influence on the global stage once again. This effort has been characterized by a mixture of traditional "hard power" and a relatively new form of "soft power." The government of the Russian Federation has developed a broad strategy for engaging the rest of the world with the intention of …

Path Planning And Control Of An Autonomous Quadrotor Testbed In A Cluttered Environment, Trevor W. Caplinger
Graduate Theses, Dissertations, and Problem Reports (ETD)
A classical problem for robotic navigation is how to efficiently navigate from one point to another and what to do if obstacles are encountered along the way. Many map based path planning algorithms attempt to solve this problem, all with varying levels of optimality and complexity. This work shows a review of selected algorithms, and two of these are selected for simulation and testing using a quadrotor unmanned aerial vehicle (UAV) in a dynamic indoor environment which requires replanning capabilities. The Dynamic A* algorithm, or simply D*, and the Probabilistic Roadmap method (PRM) are used in a scenario designed to …
Dimensions Of The Use Of Volunteered Geographic Information In Mass Crisis Events, Xiannian Chen
Dimensions Of The Use Of Volunteered Geographic Information In Mass Crisis Events, Xiannian Chen
Graduate Theses, Dissertations, and Problem Reports (ETD)
Recent studies have suggested that catastrophic events that trigger mass evacuation require surrounding communities to be well-prepared to act as ingress or pass-through areas for potential evacuees; however surrounding rural communities may have insufficient disaster-related logistical resources. In the response phase of disaster management, officials must be able to deploy resources to demand locations in types and quantities based on real-time requirements. Effective cross-jurisdictional disaster management needs real-time information, which is usually unavailable from official, authoritative sources. Conversely, VGI (volunteered geographic information) has the capability to provide real-time and local information in disaster management. This study investigates the possibility of …
A Parallel Programmer For Non-Volatile Analog Memory Arrays, Spencer L. Clites
A Parallel Programmer For Non-Volatile Analog Memory Arrays, Spencer L. Clites
Graduate Theses, Dissertations, and Problem Reports (ETD)
Since their introduction in 1967, floating-gate transistors have enjoyed widespread success as non-volatile digital memory elements in EEPROM and flash memory. In recent decades, however, a renewed interest in floating-gate transistors has focused on their viability as non-volatile analog memory, as well as programmable voltage and current sources. They have been used extensively in this capacity to solve traditional problems associated with analog circuit design, such as to correct for fabrication mismatch, to reduce comparator offset, and for amplifier auto-zeroing. They have also been used to implement adaptive circuits, learning systems, and reconfigurable systems. Despite these applications, their proliferation has …
Effects Of Protein Supplementation On Parasitism And Growth In Grazing Lambs, Crista Crawford
Effects Of Protein Supplementation On Parasitism And Growth In Grazing Lambs, Crista Crawford
Graduate Theses, Dissertations, and Problem Reports (ETD)
Controlling gastrointestinal nematode infection of sheep has become a challenge resulting from reduced anthelmintic efficacy. Previous data have indicated that grazing lambs supplemented with a 16% CP ration at 1% BW maintained growth comparable to lambs given anthelmintic despite greater infection. Thus the objective of the following studies was to determine the effects of bypass protein on fecal egg count reduction and post weaning growth in parasitized, grazing lambs. Experiment one utilized spring-born Suffolk crossbred lambs separated into 3 supplement groups: alfalfa pellets (AFP) (15% CP), corn and soybean meal (CSM) (19% CP) and corn, soybean meal and fish meal …

Coal Quality Management Model For A Dome Storage (Ds-Cqmm), Manuel Alejandro Badani Prado
Coal Quality Management Model For A Dome Storage (Ds-Cqmm), Manuel Alejandro Badani Prado
Graduate Theses, Dissertations, and Problem Reports (ETD)
Coal quality (ash, sulfur, moisture and BTU) is one of the key aspects for both coal mines and power plants. Mines invest time as well as economic and technological resources in order to manage coal quality for final use in power plants. In order to deliver uniform coal quality to the power plant, there is a need for a real-time monitoring of coal quality from the mine to the coal stockpiles. The specific problem represents the process of stacking the coal inside the enclosed facility such as a dome. The process of stacking coal inside a dome generates the unique …
