Description: The etudes of Chopin are masterworks of the piano literature and are designed to go beyond mere technical exercises; moreover, each etude represents not only a technical study but also has a distinct musical character. Alarmingly, the current trend seems to be to assign the Chopin etudes at an increasingly young age to students who are not yet equipped either technically or musically to handle them. As Chopin’s pupil, Carl Mikuli, commented in the preface to his Chopin edition, the etudes were meant for “more advanced students.” If Chopin had intended his etudes for students at an intermediate level, he would have assigned them to most of his students; however, only a limited number of students had his permission to work on their master’s etudes. As a teacher, I have always felt the need to devise a systematic teaching plan to guide students to handle the challenges of these pieces both physically and musically. This study examines the repertoire which might help prepare a student to learn the etudes without overstraining his/her muscular and mental ability. Rooted in Chopin’s teaching and his recommendation of the pieces to learn before tackling the etudes themselves, this pedagogical study guide intends to help ...

Creator: Lyons, Renée Kathleen
Description: This two-part thesis includes a critical preface and a collection of my poems. Using three poems-Louise Glück's "Lullaby," Bob Hicok's "Poem for My Mother's Hysterectomy," and Nick Flynn's "Memento Mori"-the critical preface examines how, in poetry, the transformation of a body negotiates trauma and triggers a conceptual shift, the creation and revision of identity, and the release of the duende's inspirational force. The collection of poetry that follows seeks to transfigure the body as a way to explore the nuanced traumas of human experience.

Description: This study examined the correlates between the dependent variables African-American and Hispanic student enrollment in Texas public higher education to the independent variables institution type, education region, faculty demographics, curricular offerings and student organizations. Data for African-American (n = 124,000) and Hispanic enrollment (n = 314,000) in all Texas public higher education institutions (n = 109) for the 2008 academic year were examined. Significant results, using a statistical significance of p = .005, were reported for two of the variables. A correlation of Pearson's r = .946 and statistical significance of p = .000 was observed between African-American student enrollment and the percentage representation of African-American faculty in the same institution. A correlation of Pearson's r = .982 and statistical significance of p = .000 was observed between Hispanic student enrollment and the percentage representation of Hispanic faculty in the same institution. The results of this study found significant relationships between the presence of African-American and Hispanic faculty and enrollment of African-American and Hispanic students. Recommendations are made for exploring these findings in further detail.

Cosmology, Extraterrestrial Life, and the Development and Character of Western European Thought in the Seventeenth and Eighteenth Centuries

Cosmology, Extraterrestrial Life, and the Development and Character of Western European Thought in the Seventeenth and Eighteenth Centuries

Date: August 2011
Creator: Simpson, Emily
Description: Cosmology, as an all-encompassing theoretical construction of universal reality, serves as one of the best indicators for a variety of philosophical, scientific, and cultural values. Within any cosmological system, the question of extraterrestrial life is an important element. Mere existence or nonexistence, however, only exposes a small portion of the ideological significance behind the contemplation of life outside of earth. The manners by which both believers and disbelievers justify their opinions and the ways they characterize other worlds and their inhabitants show much more about the particular ideas behind such decisions and the general climate of thought surrounding those who consider the topic. By exploring both physical and abstract structures of the universe, and specifically concepts on the plurality of worlds and extraterrestrial life, Western European thought in the seventeenth and eighteenth centuries reveals not an era of pure advancement and modernization, but as a time of both tradition and change.

The Counterinsurgency Dilemma: The Causes and Consequences of State Repression of Human Rights in Civil Wars

The Counterinsurgency Dilemma: The Causes and Consequences of State Repression of Human Rights in Civil Wars

Creator: Quinn, Jason Michael
Description: In this project a theory of adaptive differential insurgency growth by the mechanism of repression driven contagion is put forth to explain variation in the membership and spatial expansion of insurgencies from 1981 to 1999. As an alternative to the dominant structural approaches in the civil war literature, Part 1 of the study proposes an interactive model of insurgency growth based on Most and Starr's opportunity and willingness framework. The findings suggest that state capacity, via its impact on state repressive behavior, plays an important gatekeeping function in selecting which minor insurgencies can grow into civil war, but contributes little to insurgency growth directly. In Part 2 of the study, I directly examine variation in insurgency membership and geographical expansion as a function of repression driven contagion. I find that repression increases the overall magnitude of insurgency activity within states, while at the same time reducing the density of insurgency activity in any one place. Despite an abundance of low intensity armed struggles against a highly diverse group of regimes around the world, I find an extremely strong and robust regularity: where repression is low - insurgencies don't grow.

Cuff-less Blood Pressure Measurement Using a Smart Phone

Cuff-less Blood Pressure Measurement Using a Smart Phone

Date: May 2012
Creator: Jonnada, Srikanth
Description: Blood pressure is vital sign information that physicians often need as preliminary data for immediate intervention during emergency situations or for regular monitoring of people with cardiovascular diseases. Despite the availability of portable blood pressure meters in the market, they are not regularly carried by people, creating a need for an ultra-portable measurement platform or device that can be easily carried and used at all times. One such device is the smartphone which, according to comScore survey is used by 26.2% of the US adult population. the mass production of these phones with built-in sensors and high computation power has created numerous possibilities for application development in different domains including biomedical. Motivated by this capability and their extensive usage, this thesis focuses on developing a blood pressure measurement platform on smartphones. Specifically, I developed a blood pressure measurement system on a smart phone using the built-in camera and a customized external microphone. the system consists of first obtaining heart beats using the microphone and finger pulse with the camera, and finally calculating the blood pressure using the recorded data. I developed techniques for finding the best location for obtaining the data, making the system usable by all categories of people. ...

Culture and self-representation in the Este court: Ercole Strozzi's funeral Elegy of Eleonora of Aragon, a Text, Translation, and Commentary.

Date: December 2010
Creator: Cassella, Dean Marcel
Description: This dissertation presents a previously unedited text by one of the most distinguished- yet neglected-Latin writers of the Italian Renaissance, Ercole Strozzi (1471-1508), a poet and administrator in the court of Ferrara. Under the Este Dukes, Ferrara became a major center of literary and artistic patronage. The Latin literary output of the court, however, has received insufficient scholarly scrutiny. The text is a verse funeral elegy of Eleonora of Aragon (1450-1493), the first Duchess of Ferrara. Eleonora was a remarkable woman whose talents and indefatigable efforts on behalf of her husband, her children, and her state, won her accolades both at home and abroad. She also served as a prototype for the remarkable careers of her two daughters, Isabella d'Este, and Beatrice d'Este, who are celebrated for their erudition and patronage of arts and letters. The text is a mirror of the Estense court and reveals to us how its members no doubt saw themselves, at the very peak of its temporal power and the height of its prestige as a center of cultural creativity. It is also important for the striking portrait it presents of Eleonora. Ercole Strozzi chose to call his poem an epicedium, an ancient minor literary ...

Date: August 2012
Creator: Melaedavattil Jaganathan, Jyothy
Description: This work presents a novel technique for data compression based on multi-residue number systems. The basic theorem is that an under-determined system of congruences could be solved to accomplish data compression for a signal satisfying continuity of its information content and bounded in peak-to -peak amplitude by the product of relatively prime moduli,. This thesis investigates this property and presents quantitative results along with MATLAB codes. Chapter 1 is introductory in nature and Chapter 2 deals in more detail with the basic theorem. Chapter 3 explicitly mentions the assumptions made and chapter 4 shows alternative solutions to the Chinese remainder theorem. Chapter 5 explains the experiments in detail whose results are mentioned in chapter 6. Chapter 7 concludes with a summary and suggestions for future work.

Design, Synthesis and Screening of Homoleptic and Heteroleptic Platinum(ii) Pyridylazolate Complexes for N-type Semiconducting and Light-emitting Devices

Creator: Oswald, Iain William Herbert
Description: A series of heteroleptic and homoleptic platinum(II) complexes has been synthesized and characterized towards their use in thin film devices such as organic light-emitting diodes (OLEDs) and organic thin film transistors (OTFTs). Pyridylpyrazolate- and pyridyltetrazolate-containing ligands were selected due to their structural rigidity and ease of functionalization. Single-crystal x-ray diffraction studies of two selected heteroleptic complexes show strong aggregation with preferential stacking into vertical columns with a varying degree of overlap of the neighboring square planar molecular units. It is shown that the close proximity of the molecules to one another in the stack increases semiconducting character, phosphorescence quantum yields, and shorter radiative lifetimes. The potential for these materials towards incorporation into high-efficiency doping free white OLEDs (DFW-OLEDs) for solid-state lighting and display applications has been realized and will be expanded upon by present and future embodiments of materials in this thesis.
