Identifying The Technical And Teacher Skills Needed By In-Service Teachers To Effectively Teach An Agricultural Mechanics Course In West Virginia, Coleton Todd Payne

Graduate Theses, Dissertations, and Problem Reports (ETD)

Agricultural mechanics remains one of the largest content sections in school-based agriculture education (SBAE). Therefore, in-service and pre-service teachers need to be effective in teaching agricultural mechanics to their students (Burris et al., 2005; Hainline & Wells, 2019). A number of studies (McKim & Saucier, 2011; Saucier et al., 2014) have identified the importance of safety in agricultural mechanics laboratories, but not the content skills specifically needed to teach the courses. The only areas of content that most new in-service teachers possess are those of basic woodworking and basic metal working. This study bases its theoretical framework off of the …

Effects Of Acute And Chronic Nicotine Administration On Choice Of Probabilistic Outcomes, Katya A. Nolder

Graduate Theses, Dissertations, and Problem Reports (ETD)

Risky choice can be operationally defined as the choice for a larger, uncertain reinforcer over a smaller, certain reinforcer. Research suggests smokers engage in more risky or maladaptive decisions when compared to nonsmokers. The relation between nicotine and risky choice could benefit from further investigation, since nicotine is the active substance of tobacco products that maintains tobacco addiction. Acute nicotine administration has shown to alter risky choice; however, since the everyday smoker uses nicotine repeatedly, more research on chronic administration is warranted and would allow for assessment of tolerance or sensitization of these effects. The present study investigated effects of …

Floating-Gate Design And Linearization For Reconfigurable Analog Signal Processing, Steven Michael Andryzcik Ii

Graduate Theses, Dissertations, and Problem Reports (ETD)

Analog and mixed-signal integrated circuits have found a place in modern electronics design as a viable alternative to digital pre-processing. With metrics that boast high accuracy and low power consumption, analog pre-processing has opened the door to low-power state-monitoring systems when it is utilized in place of a power-hungry digital signal-processing stage. However, the complicated design process required by analog and mixed-signal systems has been a barrier to broader applications. The implementation of floating-gate transistors has begun to pave the way for a more reasonable approach to analog design. Floating-gate technology has widespread use in the digital domain. Analog and …

Association Of Incident Cancer To Low-Value Care And Healthcare Cost Burden Among Elderly Medicare Beneficiaries, Chibuzo Iloabuchi

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the United States (US), 25% of healthcare spending is considered wasteful because it is spent reimbursing low-value care. Low-value care is the utilization of healthcare services, medical tests, and procedures that have unclear or no clinical benefit to patients but still exposes them to risk. World-wide, low-value care imposes a significant economic burden on patients, payers, governments, and society. Cancer care among older adults > 65 years is one of the biggest drivers of healthcare expenditure in the US and accounts for nearly 40% of all spending, and low-value care among cancer patients is prevalent and contributes to the financial …

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Mid-Atlantic region (MAR) of the U.S. is subjected to a variety of stressors that affect the headwaters of the major rivers. Some of these stressors are abandoned mine drainage, agriculture, municipal point sources, urban areas, out-of-basin diversions, competing water uses, rapid population growths in the lowlands, alterations in water availability due to climate change and habitat alteration. In addition to these regional stressors, the rapid population growths and energy sources shifting have resulted in changes in land use and land cover (LULC) over the last few decades. The interactive effects of LULC and interannual/long-term climate changes have resulted in …

Discriminative Stimulus Effects Of Cannabidiol Oil In Rats, Rebecca L. Chalme

Graduate Theses, Dissertations, and Problem Reports (ETD)

Cannabidiol (CBD) is one of the major centrally active phytocannabinoid components of cannabis, and has been approved by the FDA only for the treatment of two rare seizure disorders. However, CBD has been touted as a potential treatment for anxiety in place of more traditional treatments like benzodiazepines. Although there is some evidence of anxiolytic effects of CBD, its suitability as a substitute for benzodiazepines is unknown. This experiment was designed to assess to what extent CBD shares interoceptive discriminative-stimulus properties with the anxiolytic chlordiazepoxide (CDP), a benzodiazepine.

In Vitro And In Vivo Toxicological Evaluation Of Emissions From The Fused Filament Fabrication Three-Dimensional Printing, Mariana T. Farcas

Graduate Theses, Dissertations, and Problem Reports (ETD)

Fused filament fabrication (FFF), a three-dimensional (3-D) printing process, is an emerging technology that has recently gained wide popularity among both consumers and manufacturers. As filament is heated to above its glass transition temperature in a 3-D printer, a portion may undergo thermal decompostion, which releases ultrafine particles (UFP) and volatile organic compounds (VOCs) with potential adverse respiratory health effects are released into the air. This study's central hypotheses is that emissions generated during 3-D printing are toxic and exposure to these emissions induces pulmonary and systemic adverse health effects. Considering that currently, limited understanding is available on the health …

An Analysis Of Coordinated Responding, Brian Katz

Graduate Theses, Dissertations, and Problem Reports (ETD)

Experimental analyses of coordinated responding (i.e., cooperation) have been derived from a procedure described by Skinner (1962) in which reinforcers were delivered to a pair of subjects (a dyad) if both responded within a short interval, thus satisfying a mutual-reinforcement contingency. Although it has been suggested that this contingency enhances rates of temporally coordinated responding, limitations of past experiments have raised questions concerning this conclusion. The present experiments assessed three of those limitations by holding the schedule of reinforcement (Experiment 1: fixed-ratio 1; Experiment 2; variable-interval 20 s) constant (1) across phases and (2) between dyad members, and (3) varying …

Effects Of Blended Integrity Failures On Reinforcement-Based Interventuions, Stephanie Hope Jones

Graduate Theses, Dissertations, and Problem Reports (ETD)

Reinforcement-based interventions reduce problematic behavior when implemented as designed. However, the effectiveness of these interventions may decrease when deviations from treatment protocols (i.e., treatment-integrity errors) occur. Treatment-integrity errors differentially impact reinforcement-based interventions based on multiple factors, including how frequently errors occur and the intervention type. Even nominally acceptable integrity values (e.g., 80%) may be detrimental depending on the intervention. To evaluate this possibility and directly compare the effectiveness of multiple reinforcement-based interventions, we conducted two within-subject evaluations using laboratory arrangements. For both experiments, we recruited four undergraduate students to participate in a computer task that involved clicking on moving circles …

A Performance Guide To Prokofiev: Romeo And Juliet For Solo Tuba, John Christopher Dicesare

Graduate Theses, Dissertations, and Problem Reports (ETD)

As the most recent brass instrument to be added to the standard orchestra, the tuba’s solo repertoire is relatively new compared to other orchestral instruments. Ralph Vaughan Williams composed the first major concerto for tuba in 1954, over 100 years after the tuba’s creation in 1835 by Wilhelm Friedrich Wieprecht and Johann Gottfried Moritz. Though many composers — including Bruce Broughton, Eric Ewazen, Paul Hindemith, Gunther Schuller, and John Williams — have written solos for the tuba since Vaughan Williams, performers rely on arrangements and transcriptions of existing works to fill gaps in the repertoire. In 2011, Chicago Symphony Orchestra’s …

Plant Species Identification In The Wild Based On Images Of Organs, Meghana Kovur

Graduate Theses, Dissertations, and Problem Reports (ETD)

Image-based plant species identification in the wild is a difficult problem for several reasons. First, the input data is subject to a very high degree of variability because it is captured under fully unconstrained conditions. The same plant species may look very different in different images, while different species can often appear very similar, challenging even the recognition skills of human experts in the field. The large intra-class and small inter-class image variability makes this a fine-grained visual classification problem. One way to cope with this variability and to reduce image background noise is to predict species based on the …
