Grit And Student Performance: A Mixed-Method Analysis Of A Non-Traditional Technical High School And A Traditional High School, Ronda L. Wallace

Dissertations

Grit, defined as the tendency to pursue long-term goals with sustained zeal and hard work, was shown to predict achievement in academic, vocational, and avocational domains. In 2009, Duckworth and Quinn found that grit predicted student effectiveness in school and the concept of grit was largely unrelated to talent. Grit provided incremental predictive validity for achievement outcomes, particularly in settings of high challenge. From the combination of persistence, self-control, and more broadly, conscientiousness, emerges the concept of grit. The purpose of this study was to compare the relative grittiness of students from two different high school settings. The first of …

Investigation Of Infinite-Dimensional Dynamical System Models Applicable To Granular Flows, Hao Wu

Dissertations

Recently Blackmore, Samulyak and Rosato developed a class of infinite-dimensional dynamical systems in the form of integro-partial differential equations, which have been called the BSR models. The BSR models were originally derived to model granular flows, but they actually have many additional applications in a variety of fields. BSR models have already been proven to be completely integrable infinite-dimensional Hamiltonian dynamical systems for perfectly elastic interactions in the case of one space dimension, but the well-posedness question of these systems is at least partially answered for the first time here. In particular, dynamical systems of the BSR type are proven …
