Adult Attachment In Close Relationships And Trait Emotional Intelligence: The Moderating Role Of Mindfulness, Laura Kimberly Chang

Dissertations

The moderating role of mindfulness on the relationships between trait emotional intelligence (TEI) and both attachment-related anxiety and avoidance among college students (N = 510) was explored in the present study. Descriptive statistics and Pearson correlations aligned with the extant body of literature, suggesting strong relationships between attachment-related anxiety, avoidance, and TEI. As expected, results suggested a strong relationship between levels of mindfulness and TEI. In the interest of assessing the degree to which mindfulness explained variance in participants’ TEI levels (while accounting for attachment levels), a hierarchical multiple regression was conducted. Data analysis indicated that the variables college classification …

Using Mindset Pedagogy To Promote Growth And Increase Efficacy In Student Writers, Sara Hoeve

Dissertations

This dissertation offers four in-depth, vivid profiles of twelfth grade writers and the ways in which writing mindsets impact self-beliefs and inform the writing process. The multiple case study explores the impact of a mindset pedagogy, which is defined as an instructional paradigm that emphasizes the malleable nature of writing, as an ability that can be developed with effort, learning, and dedication over time. This belief contrasts the notion that writing ability is fixed trait that cannot be significantly developed over time.

Derived from Dweck's mindset theory, my dissertation argues for a discipline-specific construct of the "writing mindset,” which refers …

Applications Of Big Knowledge Summarization, Ling Zheng

Dissertations

Advanced technologies have resulted in the generation of large amounts of data ("Big Data"). The Big Knowledge derived from Big Data could be beyond humans' ability of comprehension, which will limit the effective and innovative use of Big Knowledge repository. Biomedical ontologies, which play important roles in biomedical information systems, constitute one kind of Big Knowledge repository. Biomedical ontologies typically consist of domain knowledge assertions expressed by the semantic connections between tens of thousands of concepts. Without some high-level visual representation of Big Knowledge in biomedical ontologies, humans cannot grasp the "big picture" of those ontologies. Such Big Knowledge orientation …

Theoretical Studies Of Photoinduced Dynamics And Topological States In Materials With Strong Electron-Lattice Couplings, Linghua Zhu

Dissertations

First, we study the nonequilibrium dynamics of photoinduced phase transitions in charge ordered (CO) systems with a strong electron-lattice interaction and analyze the interplay between electrons, periodic lattice distortions, and a phonon thermal reservoir. Simulations based on a tight-binding Hamiltonian and Boltzmann equations reveal partially decoupled oscillations of the electronic order parameter and the periodic lattice distortion during CO melting, which becomes more energy efficient with lower photon energy. The cooling rate of the electron system correlates with the CO gap dynamics, responsible for an order of magnitude decrease of the cooling rate upon the gap reopening. The work also …

Myosin Assembly Into Elongating Thick Filaments Is Dependent On The Function Of Conserved Apmk-Related Kinase Unc-82 In C. Elegans, Natasha R. Schiller

Dissertations

The mechanism of assembly of sarcomeric myosins into elongating thick filaments is not well understood. The results of this study suggest a novel mechanistic model in which the AMPK-related kinase UNC-82, which is orthologous to mammalian ARK5/NUAK1 and SNARK/NUAK2, acts as an assemblase on sarcomeric myosin molecules, mediating their addition into the elongating thick filaments of C. elegans body-wall muscle. The classical genetic crosses performed in this study produced over 53 different worm strains that contain thick-filament-affecting mutations and/or transgenes in single-, double- or triple-mutant combinations. The phenotypes of these strain were documented and analyzed using viability assays, brood analysis, …

Effects Of Multi-Day Music Enrichment On Salivary Cortisol And Cage Behavior In Shelter Dogs, Stacy D. Engerbretson

Dissertations

Rehoming shelters provide their animals with environmental enrichment with the expectation that modifying the physical space will improve kennel-related stress and subsequently abate undesirable behaviors. Although enrichment has shown moderate success at improving in-kennel behavior, increased use of physiological measurements of stress, such as cortisol, has garnered doubt as to which canine behaviors are truly elicited by a biological state of distress. Consequently, it is unknown if past examples of successful kennel enrichment decreased biological stress in addition to affecting behavior. This study explored music’s effect on salivary cortisol and music’s potential as a long-term, kennel enrichment strategy. Shelter dogs …
