The Effects Of Ability Grouping On Gifted & Talented Third, Fourth, And Fifth Grade Students In Selected South Carolina Public School Districts, Tammy Tara White

Theses and Dissertations

This is a quantitative research study using archival data to focus on the achievement of Gifted & Talented students in two South Carolina public school districts. The researcher used an open cohort comparative research design for this study. This study attempted to find if differences in student performance existed between students labeled as Gifted & Talented in South Carolina based on their model for instruction. The researcher used their Palmetto Assessment of State Standards (PASS) test scores in English Language Arts (ELA) and math achievement scores and compared them to the students' placement in special class model Gifted & Talented …

Dual-Phase Mixed Ion And Electron Conducting Co2-Selective Permeation Membranes, Lingling Zhang

Theses and Dissertations

Fossil fuels are the dominant energy source powering our modern society. However, burning fossil fuels emits carbon dioxide (CO2), a greenhouse gas that can cause climate change and ultimately threaten the survival of humanity. Effectively mitigating CO2 emissions from the use of fossil fuels has become an intense subject of scientific research as well as political debate in recent years. The current mainstream technical approach to achieving that goal is to curb the emission of CO2 by capturing CO2 at point-sources and geologically storing it. The CO2 separation and capture process, the first step toward the ultimate storage of CO2, …

Forgotten Russian Piano Music: The Sonatas Of Anatoly Aleksandrov, Irina Pevzner

Theses and Dissertations

This historical and analytical study focuses on the piano sonatas of Anatoly Aleksandrov (1888-1982), the longest-living Russian and Soviet composer-pianist of the twentieth century. The fourteen piano sonatas, written between 1922 and 1971, reflect not only the composer's evolution of style, but also reveal the vast array of influences which characterize the music of the twentieth century. Chromaticism that results from stretched harmonic sequences, strong melodic lyricism that threads these epic compositions, rich writing for piano, and hints of Russian folklore all contribute to the composer's original style, which synthesizes Aleksandrov's four main figures of influence, namely Rachmaninov, Scriabin, Medtner, …

Comparative Audiation Difficulty Of Tonal, Rhythm, And Melodic Patterns Among Grade 4 Students, Alan Danahy

Theses and Dissertations

The purpose of this research was to investigate the audiation difficulty of melodic patterns. The specific research problems of this study were to: (a) examine the relationships between the audiation difficulty of melodic patterns compared to the audiation difficulty of their embedded tonal patterns and embedded rhythm patterns, (b) determine if tonal pattern difficulty and/or rhythm pattern difficulty may be used to predict melodic pattern difficulty, (c) examine the mean differences between the audiation difficulty of melodic patterns compared to the audiation difficulty of their embedded tonal patterns and embedded rhythm patterns, and (d) examine the mean differences between the …

Renewable Bio-Based Polymers And Degradable Functional Polymers, Kejian Yao

Theses and Dissertations

In this dissertation, polymers derived from renewable bio-based resources and degradable functional polymers with stimuli-responsive properties by various polymerization techniques were investigated. The properties of these polymeric materials were characterized and discussed.

In Chapter 1, the overall background and recent development of renewable bio-based polymers as well as degradable stimuli-responsive polymers was introduced. Major research objectives of my doctoral work were described.

The first section of the dissertation, on the preparation of renewable bio-based polymers was provided from Chapter 2 to Chapter 4. In Chapter 2, the preparation of novel polymers derived from renewable gum rosin by atom transfer radical …
