There has been relatively little study of the efficacy of decommissioned oil and gas platforms as artificial reef habitats for fish assemblages in the northern Gulf of Mexico (GOM). A variety of fish species have been reported on these structures, but the species biomass distribution and community structure has not been studied thoroughly. Hydroacoustic and video survey....

The Agricultural Act of 2014, signed February 7, 2014, introduces a new era of federal support in the production of major agricultural commodities in the United States for the 2014 through 2018 crop years. The ultimate result of the Act was a 954-page piece of legislation that represented market-oriented policies such as the creation of an area-wide shallow loss revenue....

Risk of disordered eating is high amongst college women in the U.S., often resulting in negative outcomes with regard to health, social functioning and psychological well-being. Disordered eating is associated with multiple aspects of emotional processing, such as emotion regulation, negative affect, and avoidance. Emotional processing difficulties can be addressed with....

During recent years, social capital has become one of the most widely used concepts in sociological literature, and its popularity has shown itself in both sociological theory and everyday language. Its increasing popularity has mainly resulted from its conceptualizations by some of the most prominent social scientists, such as Pierre Bourdieu, James Coleman, Nan Lin, a....

Tsunamis and hurricane induced waves are responsible for many coastal bridge failures, especially in the last decade. In the current study, three countermeasures (reducing the entrapped air, elevating the structures and rigidifying the structures) are considered, two wave types (solitary wave theory and Stokes wave theory) are chosen, and two bridge types (single bridge....

The ongoing softwood lumber trade dispute between the United States (U.S.) and Canada is one of the most contentious and largest bilateral trade battles over the recent decades. The bilateral trade debate is mostly because of the different forestland ownership systems in the U.S. and Canada, and the alleged timber subsidies by provincial governments to Canadian lumber p....

Working alliance has been shown to predict positive psychotherapy treatment outcomes. Past research focuses on therapist characteristics that correlate with working alliance after multiple therapy sessions (e.g., warmth, trustworthy) rather than employing experimental designs examining specific techniques that quickly improve working alliance. Specific techniques that h....

We have investigated the electronic structure of environmentally persistent free radicals (EPFRs) formed on two different metal oxides: Cu(II)O and ZnO. Cu(II)O is known to be one of the most active metal oxides to form EPFRs. ZnO, however, forms the longest-lived EPFRs. First, we examined the adsorption of phenol on different crystal faces of ZnO. Ultraviolet photoele....

The tail of a sequence {P_n(q)} of formal power series in Z[q^{-1}][[q]], if it exists, is the formal power series whose first $n$ coefficients agree up to a common sign with the first n coefficients of P_n. The colored Jones polynomial is link invariant that associates to every link in S^3 a sequence of Laurent polynomials. In the first part of this work we study the t....

Chemical exchange saturation transfer (CEST) and magnetization transfer (MT) are types of magnetic resonance imaging (MRI) experiments in which contrast is based on the transfer of magnetization from selectively saturated solute or macromolecular protons to bulk water protons. These processes offer insight into the chemical composition of tissue and are quantified by th....

Many problems related to synthesis with intelligent tutoring may be phrased as program synthesis problems using AI-style search and formal reasoning techniques. The first two results in this dissertation focus on problem synthesis as an aspect of intelligent tutoring systems applied to STEM-based education frameworks, specifically high school geometry. Given a geometric....

The purpose of this study was to explore how closely upper elementary magnet school reading teachers perceptions of evidenced-based practices in reading compared to actual practices in their classrooms. Literacy instruction, beginning in the third grade, places more emphasis on comprehension and higher expectations on the students than in the early elementary grades. Th....
