Mindfulness As A Moderator Of Coping Response And The Abstinence Violation Effect : A Test Of The Role Of Mindfulness In The Relapse Prevention Model For Exercise., Christi S. Ulmer 1964-

Electronic Theses and Dissertations

The importance of physical activity in preventing disease and promoting health is increasingly evident in health outcomes research. Although most adults in the U.S. have initiated exercise programs at some point in their lives, research suggests that they have difficulty maintaining beneficial levels of physical activity and exercise. With escalating rates of obesity and physical inactivity, the importance of understanding processes by which individuals engage in and maintain physical activity cannot be understated. The Relapse Prevention Model (RPM), developed for use with addiction, has been successfully used to explore factors associated with exercise drop-out, or "exercise relapse". In the ...


Gary Snyder's Idiosyncratic Buddhist Poetics And The "Razoredge"., David Gerhardt Thimme 1970- Dec 2006

Gary Snyder's Idiosyncratic Buddhist Poetics And The "Razoredge"., David Gerhardt Thimme 1970-

Electronic Theses and Dissertations

Gary Snyder's poetry conveys Zen states of consciousness through unconventional grammar and syntax. From his first book Riprap in 1959 to his last collection of poems, Mountains and Rivers Without End in 1996, he has confronted the challenge of transforming Buddhist philosophy and discourse into Western poetics. Snyder's syncretism pertaining to Buddhist and Native American beliefs form a unique view of Zen that suggests his precise involvement with the meditative self-discipline may be unstable and elusive. A close reading of Snyder's idiosyncratic Buddhist poetics reveals an impasse between a "non-verbal" realm, where the Cartesian duality of subject ...


Psychopathy Factors And Degree Of Forcefulness In Sex-Offenders : Implications For Current Risk-Assessment Practices., Luciano Tristan Dec 2006

Psychopathy Factors And Degree Of Forcefulness In Sex-Offenders : Implications For Current Risk-Assessment Practices., Luciano Tristan

Electronic Theses and Dissertations

Based primarily on theory, it is suspected that violent and non-violent sex-offenders can be differentiated by their psychopathic profile, as measured by the Psychopathy Checklist-Revised (PCL-R; Hare, 1991). There is some concern that current risk-assessment instruments are not designed according to the characterological composition of violent and non-violent sex-offenders, which is believed to be essential to the instruments' predictive ability. Specifically, it is believed that such instruments are not sufficiently sensitive to the psychopathic characteristics associated with non-violent sex-offenders, as well as not sufficiently specific to the psychopathic characteristics associated with violent sex-offenders. A sample of convicted sex-offenders (N = 1739 ...

Geomorphic Considerations For Restoration Of Headwater Streams Impacted By Mountaintop Mining Hollow Fills., Ben Mater 1982- Dec 2006

Geomorphic Considerations For Restoration Of Headwater Streams Impacted By Mountaintop Mining Hollow Fills., Ben Mater 1982-

Electronic Theses and Dissertations

Within the Appalachian hills of eastern Kentucky, large-scale coal mining operations are directly altering the headwater landscape through the construction of hollow fills. These man-made landforms and their associated in-stream structures alter a longterm, continuous morphologic evolution driven by the natural interaction of erosive forces and material of the earth's surface. Post-mining channel morphology, hillslopes, and hollow fills continue to actively evolve in response to erosive forces. Aquatic ecosystem functionality and hollow fill stability may be jeopardized by this condition, yet they may be preserved through efforts to restore or re-create channel morphology more representative of the natural headwater ...

A Robotics Testbed : The Design & Implementation With Applications., Travis Alan Riggs

Electronic Theses and Dissertations

In order to study the movements of autonomous mobile robots, a tool is needed to quantify those movements. A testbed is an apparatus that provides a designated space for multiple mobile robots while tracking their position in real-time. That tracking information can also be communicated to the robots themselves to serve as closed-loop feedback. With this tool, many techniques can be developed and validated through various control experiments. A design and implementation of a testbed is presented here. The testbed is analyzed for its performance and several applications are presented to demonstrate its usefulness.

Electronic Theses and Dissertations

In 2003, Wilson Creek running through Bernheim Arboretum and Research Forest in central Kentucky was restored to its original winding path through a valley field. Early 20th century settlers had previously redirected this creek to run a straight path along the eastern hillside in order to maximize the valley for farming. As part of the restoration to its pre-settler path, seven ponds were created in the corridor of the old streambed, which created habitat for pond-breeding amphibians. Sampling began one year after construction was complete, and over two years the amphibian assemblages of these ponds were compared to those of ...

Animal Experiment (Rabbit) To Demonstrate Changes In Trabecular Bone Mechanical Properties Over Time Using Finite Element Analysis., Shuo Yang 1974- Dec 2006

Animal Experiment (Rabbit) To Demonstrate Changes In Trabecular Bone Mechanical Properties Over Time Using Finite Element Analysis., Shuo Yang 1974-

Electronic Theses and Dissertations

Decreased strength of trabecular bone is a direct effect of osteoporosis, which can be evaluated by finite element analysis. However, computational limitations have restricted previous trabecular bone analyses primarily to the linear domain. In addition, previous work was largely invasive and the corresponding finite element models were typically homogeneous. Nonlinear heterogeneous finite element analysis was used to calculate trabecular bone apparent strength directly from in vivo micro computational tomography (micro-CT) scans. Through a series of validation experiments, it was shown that this nonlinear modeling is more accurate in evaluating trabecular bone mechanics in osteoporosis than previous work. A parameter driven ...

Rhetorics Of Globalism., Steven Nathaniel Wexler Dec 2006

Rhetorics Of Globalism., Steven Nathaniel Wexler

Electronic Theses and Dissertations

This project examines the rhetorics that enable nations to tap into and deploy capital transnationally. Its primary focus is on China. China's globalism promotes a version of Western neoliberalism, including tropes such as efficiency, individuality, and freedom, to underwrite inequality, consumerism, and masking of surplus labor/value. While an ostensible boon for China's marginalized, China's globalism continues to increase the gap between wealthy and poor. Chapter One introduces the project with an overview of theoretical and disciplinary responses to globalization. This chapter demonstrates how the discourse of transnational capital supports consumerism, competition, and simultaneous "universality/difference" worldwide ...

The Effect Of Modular Tapered Fluted Stems On Proximal Stress Shielding In The Human Femur., Justin Steve Conway

Electronic Theses and Dissertations

Modular hip implants are currently being used in total hip arthroplasty revision procedures because it is common to have little or no bone left in the proximal region of the femur and it is difficult to accurately size implants based off of radiographs or other medical imaging techniques. The effect of modular systems using tapered fluted stems on proximal stress shielding in the human femur is the focus of this study. Seven modular implants were press-fit into seven femurs, where there was little or no contact between the modular body and the test femur. Finally, hydroxyapatite bone cement was added ...


Syllable Systems : Four Students' Experiences In Learning Rhythm., Tammy Renee Fust Dec 2006

Syllable Systems : Four Students' Experiences In Learning Rhythm., Tammy Renee Fust

Electronic Theses and Dissertations

This qualitative study examines the effect of two different syllable counting systems on four sixth-grade band students. The goal of this study was to see the differences and similarities between rhythm learning and performance between these students in four related case studies. During a series of five lessons, students spent time with the researcher individually exploring rhythm reading and performing on their instrument. Two of the students were taught to count rhythms with the "takadimi" rhythm syllable system as developed by Richard Hoffman, William Pelto, and John White. The other two students counted rhythms using the traditional "l-e-&-a" system of counting most familiar to instrumental teachers in the United States. Subjects' experiences in counting rhythms using these systems were compared and contrasted to find what similarities or differences existed. Lessons with each student were also videotaped, and the lessons were transcribed to ascertain trends and differences between each teaching setting and rhythm system. This was also done to have a complete record of each teaching period. The researcher also kept a journal for reflection after each lesson in order to better understand and reflect on student learning. Data collected from the videotape transcripts reflected that students made mistakes that fell into six categories: (1) holding a note or rest too long, (2) playing a note or rest too short, (3) wrong syllable used, (4) unsteady pulse, (5) stops and hesitations due to rushing, and (6) incorrect rhythm. Analysis of this data resulted in identifying specific problems arising from the two rhythm methods used. Results showed that there were no apparent differences in achievement between the two approaches to learning rhythm. The students, regardless of method, generally made the same types of errors when counting and playing rhythms; they made ...
