Effects Of Delay Order And D-Amphetamine On Delay Discounting In Rats, Shana R. Bailey Dec 2011

Effects Of Delay Order And D-Amphetamine On Delay Discounting In Rats, Shana R. Bailey

Graduate Theses, Dissertations, and Problem Reports (ETD)

Impulsive choice is defined as choice for a smaller, more immediate reinforcer over a larger, more delayed reinforcer, whereas self-controlled choice is defined as choice for a larger, more delayed reinforcer over a smaller, more immediate reinforcer. Determinants of impulsive and self-controlled choices may be studied by employing delay-discounting procedures. When using a discrete-trials delay-discounting procedure, a difference in delay discounting as a function of order of presentation of delays to larger-reinforcer delivery was reported by one previous study, whereas another study reported no differences. In both studies, subjects had a history of exposure to both ascending and descending order …

Exploring Influences On Parent Support For Child Physical Activity In West Virginia, Jill A. Nolan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Physical activity enhances child health. On average, boys are more active than girls. The causes of this disparity are not fully known, but are likely due to factors at multiple levels including individual, interpersonal, organizational, community, and policy. Further, gender stereotypes that associate males with sports and physical activity behavior may also influence child physical activity. What is known is that girls benefit from physical activity just as boys do, and that parental support for boys' physical activity is generally higher than is parental support for girls. Additionally, parental supportive behavior for childhood physical activity is positively associated with increased …


Nanosize Effects In The Magnetic Properties Of The Two Layered Hydroxides Of Nickel, James D. Rall Aug 2011

Nanosize Effects In The Magnetic Properties Of The Two Layered Hydroxides Of Nickel, James D. Rall

Graduate Theses, Dissertations, and Problem Reports (ETD)

Investigations of properties of materials with lower lattice dimensionality (one and two dimensions) often provides good opportunity to advance physics since solutions to corresponding theoretical models are more easily obtained. In this work, results on magnetic properties of two quasi two-dimensional (2D) systems viz. the layered hydroxides of nickel, beta-Ni(OH)2 and alpha-Ni(OH)2, are reported. For beta-Ni(OH)2, there have been conflicting reports in the literature whether the magnetic ordering is ferromagnetic or antiferromagnetic. For the less stable alpha-Ni(OH) 2 with the larger spacing between the layers, the nature of magnetism is largely unexplained. Therefore, the results and their interpretation present here …

Spatial Features Of Okun's Law Using U.S. Data, Casto Martin Montero Kuscevic Aug 2011

Spatial Features Of Okun's Law Using U.S. Data, Casto Martin Montero Kuscevic

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation addresses issues related to the regional labor market interactions within the United States using the Okun's Law as theoretical framework. In chapter one I estimate the state-level Okun's law after accounting for national changes and spatial spillovers. The estimates show that state-specific growth has a small effect on state unemployment rate changes. State growth experiences that are part of national or regional growths have a substantially bigger effect on state unemployment rates. I compare my results with international data which show a much larger association after accounting for time effects and spatial spillovers; implying that uncoordinated state-level demand …

Characterization And Genetic Manipulation Of Ergot Pathway Inefficiency In Fungi, Prashanthi Mulinti Aug 2011

Characterization And Genetic Manipulation Of Ergot Pathway Inefficiency In Fungi, Prashanthi Mulinti

Graduate Theses, Dissertations, and Problem Reports (ETD)

Ergot alkaloids are mycotoxins that negatively affect humans and animals but also have useful pharmaceutical properties. Ergot alkaloids have been extensively studied in Claviceps purpurea, and also have been reported in other fungi, such as certain Penicillium spp., Aspergillus fumigatus, and several Neotyphodium spp. that are endophytes of grasses. There is a high degree of variation in the production of ergot alkaloids within an individual species and among producers from different taxa, which means different fungi accumulate different profiles of ergot alkaloids rather than a single pathway end product. These varied profiles result, in part, from inefficiency in the pathway …
