  • Associations Between Parenting Practices and Decision-Making Competence inEmerging Adults: A Prospective Study

    Creator:
    Michaels, Linsie
    Abstract:
    Developmental research has suggested that parenting practices may impact the development of risk behaviors later in life. However, little evidence exists regarding how parenting may impact actual decision processes that precede poor choices. This study examined how parenting practices in early childhood influence the development of decision-making competence (DMC), a...

  • Individual Differences in Intuitive Risk Judgments

    Creator:
    Brunot, Alexander N.
    Abstract:
    The present research sought to investigate individual differences in the way individuals process intuitive risk judgments. The present investigation is centered on Fuzzy Trace Theory (Brainerd & Reyna, 1991), a developmental dual process theory of cognition which posits two ways in which individuals process information, gist and verbatim processing. 228...

  • Development of a Boiling Surface Effectiveness Parameter by Modeling and Quantifying the Net Coolant Flow Rate

    Creator:
    Harrison, Matt
    Abstract:
    Boiling dynamics and related heat transfer mechanisms have been widely studied for several decades. During that time, incredible progress has been made on quantifying bubble departure phenomena including growth rate, departure frequency, associated natural and forced convection, and radiation additions to the overall heat transfer rate. With this, the thermal...

  • Thermal and Aerodynamic Effects of Surface Roughness Patterns on Additive Manufactured Heat Sinks

    Creator:
    Lundeen, Samuel L.
    Abstract:
    Breakthroughs in heat sink design are now limited by conventional manufacturing techniques which can only produce basic fin shapes with homogenous surface structuring. Additive Manufacturing (AM) is a potential disruptive technology for heat sink design and other convective heat transfer solutions, as surface properties can be directionally varied to maximize...

  • Substitution Effects on the Structure and Electronic Behavior of Ternary Precious Metal Oxides

    Creator:
    Flynn, Joshua
    Abstract:
    Due to the high cost of precursor materials, complex oxides of 4d and 5d transition metals are under-studied compared to their 3d counterparts. Recent studies have shown that oxides containing heavier transition metals can exhibit exotic electronic states due to presence of strong spin-orbit coupling. The goal of this dissertation...

    Creator:
    Mathews, Joshua A.
    Abstract:
    Background: The use of high-Z nanoparticles as radiation dose enhancers has been researched thoroughly over the past decade. High-Z nanoparticles introduced to a medium increase the probability of photoelectric absorption. This leads to an increase in the production of short range characteristic and Auger electrons and, thus, local radiation dose....
