Structure, Stratigraphy, And Tectonics Preserved Of The Northwestern Bays Mountain Synclinorium, Greene And Hawkins Counties, Northeast Tennessee, John G. Bultman

Masters Theses

The Bays Mountain synclinorium and surrounding area provide critical facies data to address Sevier-Bountian basin development. This area preserves the Middle Ordovician post-Knox unconformity, the Sevier-Blountian basin depositional sequence, overlying Bays Formation quartz arenite-redbed sequence, the Bays/Martinsburg unconformity, and the base of the overlying Caradocian Martinsburg clastic wedge. Detailed geologic mapping in the Northwestern half of the Sevier-Blountian basin has divided the Sevier Shale into three members: a lower thin-bedded, dark gray-black, graptolite-bearing shale overlain by dark gray-black micritic limestone; a middle siltysandy limestone interbedded with light gray silty shale and calcareous sandstone; and an upper thick-bedded light gray shale …

An Investigation Of The Predictive Validity Of Broad And Narrow Personality Traits In Relation To Academic Achievement, Jessica A. Dunsmore

Doctoral Dissertations

The purpose of this dissertation was to determine the ability of broad and narrow personality traits to predict academic achievement over time in adolescence. Analyses were conducted on a sample of 1328 adolescents from an archival data set. Students were in grades 6, 9, and 12 at time one, and measures were assessed over three consecutive annual testing occasions. Results from correlational analyses showed that all Big Five traits predicted academic performance at Time One and Time Two. All Big Five traits except for Openness predicted academic performance at Time Three. Additional correlational analyses demonstrated that the narrow traits of …

Adolescent Sexual Behaviors: Analyses Of Context, Catherine Marie Grello

Doctoral Dissertations

The three studies presented in this paper together examined personal, psychological, and relational variables and their association to adolescent sexual behaviors. By examining adolescent sexual behaviors in the context in which they are embedded and adding to our questions, non-coital sexual behaviors, the two studies presented here provide evidence that the relationship context is an important consideration. For some adolescents engaging in sexual behaviors is likely symptomatic; however, for others engaging in sexual behaviors is less problematic.

The Other-Directed Adolescent: Associated Personality Processes As Measured By The Rorschach, Elisabeth D. Scherpenisse

Doctoral Dissertations

Other-Directedness examines the extent to which a person sees his or her contemporaries as a source or guide for how to behave in a given situation. It has been linked with both adjustment difficulties and difficulties in interpersonal functioning. The purpose of this study was to examine underlying personality processes using the Rorschach in the late adolescent, college population and the hypotheses were three-fold. It was hypothesized that highly Other-Directed adolescents would have fewer psychological resources for coping with stress as indicated by a low Adjusted D score. It was hypothesized that highly Other-Directed adolescents would have less effective attitudes …

James Fenimore Cooper, Professional Authorship, And The American Literary Marketplace, 1838-1851, Steven P. Harthorn

Doctoral Dissertations

This dissertation is a primary-source-intensive literary history that makes use of publishers' records, correspondence, manuscript evidence, and literary works to study how James Fenimore Cooper refashioned his career as a professional author during its last major phase, approximately 1838 to 1851, to adapt to changing conditions he faced in the literary marketplace and to confront challenges-both externally- and self-imposed-to his status and reputation.

Chapter One, "The Tortured Profession of Authorship: Novelist Again," narrates Cooper's return to fiction in 1837-38, considering the professional issues confronting him at the time, such as economic uncertainties, constraints of the typical two-volume format, and alienation …

Absenteeism And Presenteeism As Related To Self-Reported Health Status And Health Beliefs Of Tennessee Safety And Health Professionals, William Tunstall Rogerson Jr.

Doctoral Dissertations

The purpose of this study was to investigate the health conditions, health status, and health beliefs of Tennessee safety and health professionals using self-reported absenteeism and presenteeism. The study collected self-reported absenteeism, which is missed work due to health conditions, and, presenteeism, which is the decrement in performance due to remaining at work while impaired by health problems. The Health Belief Model was used as the theoretical framework for the study.

Two valid and reliable instruments were adapted for this study. "The Wellness Inventory," by Dr. Ron Goetzel and associates at Cornell University, and "The Health Beliefs Questionnaire," by Dr. …

Modification And Evaluation Of Continuous Roll Prediction Model For Front Drive Mowers, Xinyan Wang

Doctoral Dissertations

The recently approved ASAE Standard S547 “Tip-Over Protective Structure (TOPS) for Front Wheel Drive Turf and Landscape Equipment” addressed a continuous roll prediction model for Roll-Over Protective Structure (ROPS) design. The existing model described in this Standard did not take into account the influence of the mower deck on the rollover behavior. In order to evaluate the accuracy of the original model, according to the ASAE S547 requirement, a 4.05 meters long and 3.42 meters wide slope of 35 degrees was constructed at the University of Tennessee. Lateral upset tests for Deere F925 front drive mower with regular and inverted …

Trapped In A State Of Mitigating Danger: Forgotten Process, Forgotten Women, Alva Hunt Reid

Doctoral Dissertations

Women who are in intimate partner abusive relationships undergo a change process, which is a spectrum of emotional and behavioral responses to violence that is identifiable in stages. The end result is that women terminate their relationships or renegotiate their circumstances to halt the violence: Treatment protocol for abused women is shifting to individualized intervention based on these stages. Leaving and returning to an abusive relationship is a predominant theme in the change process that has not been investigated.

The present study examined this forgotten leave-return process in a sample of forgotten women. Grounded theory methodology was utilized to describe …

Photochemical Reactions Of Optically Active Chiral And Achiral Organic Materials, Nicie Conley Murphy

Doctoral Dissertations

Sodium chlorate, NaClO₃, which crystallizes in the space group P2₁3, forms optically active crystals upon crystallization although the molecule itself is achiral. NaClO₃, has been shown to produce an asymmetric distribution of (+) and (-) crystals when crystallized from water while stirring. It has been discovered that beta or positron radiation can also induce asymmetric crystallization in NaClO₃ solutions. Like NaClO₃, achiral 4,4’-dimethylchalcone crystallizes in enantiomeric forms in the space group P2₁3. Kondepudi et al. provided evidence that stirred crystallizations of 4,4’-dimethylchalcone can induce a bimodal distribution of …

The Role Of Viruses In Fe Recycling In The World's Oceans, Leo Poorvin

Doctoral Dissertations

Viral lysis is responsible for a significant fraction of bacterioplankton mortality in marine systems. This work shows that viral lysis of both heterotrophic bacterial and autotrophic cyanobacterial plankton releases iron (Fe) at a greater rate than is released from unlysed cells. These studies also show that the Fe released is bound to organic ligands, these ligands are not siderophores, and that these ligands have Fe binding stability constants similar to organic ligands found in seawater. Further, these studies have shown Fe released via viral lysis to be highly bioavailable to a range of model marine plankton and may potentially satisfy …

Black Children And Northern Missionaries, Freedmen's Bureau Agents, And Southern Whites In Reconstruction Tennessee, 1865 -1869, Troy Lee Kickler

Doctoral Dissertations

This dissertation explores one of the forgotten characters of Reconstruction and African American history: the black child. It begins with the experiences of young black Tennesseans during slavery and the Civil War. then examines their lives after freedom within and outside the family and schools, and ends with an account of their memory of Reconstruction.

During Reconstruction, black children's lives were affected daily by the ideological conflict among freedmen, white Southerners, Bureau agents, and Northern missionaries. By and large slave children had experienced a childhood-thanks to the efforts of slave parents in sustaining family bonds. Yet after the tumultuous change …

Understanding Immune Response In Mycobacterium Ulcerans Infection, Sarojini Adusumilli

Doctoral Dissertations

Buruli ulcer is a necrotizing skin infection and is the third most important mycobacterial disease in immune competent individuals after tuberculosis and leprosy in humid tropical countries. The causative agent Mycobacterium ulcerans is unlike other mycobacterial pathogens in that it appears to maintain an extracellular location during infection. Another unusual feature of the bacterium is that it is the only mycobacterium known to produce a dermo-necrotic polyketide toxin called mycolactone. A single Buruli ulcer, which can cover 15% of a person's skin surface, contains huge numbers of extracellular bacteria. The infection is characterized by massive necrosis at the site of …

Psychopathic Traits In College Students: Electrodermal Reactivity, Anxiety, Disinhibition, Risk-Taking, And Executive Functioning, Robert L. Bare

Doctoral Dissertations

A robust finding is that psychopaths exhibit electrodermal hyporeactivity in the presence of stimuli that elicit anxiety in non-psychopathic samples. This finding has been associated with decreased anxiety, although recent research suggests the relationship between psychopathic traits and electrodermal hyporeactivity may be related to other correlates of psychopathy (i.e. decreased inhibitory control, risk-taking, and executive functioning deficits). The present study was a preliminary examination to assess electrodermal reactivity, disinhibition, risk-taking, and executive functioning in a sample of undergraduate students with varying degrees of psychopathic characteristics. Results generally did not support hypothesized relationships between psychopathic traits, physiological responsivity, and executive functioning …

A Qualitative Study Of Teachers' Perceptions Of Integrated Kindergarten Programs In Hong Kong, Wai Yung Cheuk

Doctoral Dissertations

Since 1985, the Hong Kong government has been collaborating with the selected non-profit private service providers to implement integrated kindergarten education in mainstream kindergarten programs initially designed for typically developing children. The term "integrated" is roughly equivalent to "inclusive" in the United States. This study's purpose is to describe kindergarten teachers' perspectives on the provision of quality integrated education for children with disabilities in Hong Kong contexts. The findings of this study offer empirical data that suggest ways to improve the quality of integrated kindergarten programs so that young children with disabilities can attain a high-quality early childhood education experience …

This doctoral dissertation research examines spatial and temporal patterns of geomorphic adjustment processes in three tributary streams of the Lower Hatchie River Basin, in west Tennessee, which are adjusting to historic land clearance and channelization. This dissertation examines (1) the types and spatial pattern of geomorphic adjustment processes in a total of 34 tributary reaches located in Richland, Jeffers, and Dry Creeks, (2) the applicability of an existing model of geomorphic adjustment for use in …

A Price On Freedom: The Problems And Promise Of The Vietnam Era G.I. Bills, Mark Boulton

Doctoral Dissertations

At the end of World War II, the federal government bestowed one of the richest rewards ever given a mass mobilized army in the form of the Servicemen's Readjustment Act of 1944, better known as the OJ. Bill of Rights. The OJ. Bill offered veterans generous loans, education benefits, and unemployment insurance to help them readjust to civilian life. The bill is widely lauded as one of the most important federal acts of the twentieth century. Further 0.1. Bills followed for veterans of the Cold War including those who served in Korea and Vietnam. Despite their continued impact on the …

Chlorpyrifos In Human Breast Milk?, Karyn Ann Casey

Doctoral Dissertations

The widespread use of pesticides by farmers, pest control operators and even the general public can pose significant risks to children's health. One particular pesticide, chlorpyrifos, was the most widely used pesticide in the United States with total use estimated at approximately 30 million pounds per year. Young children and the developing fetus are far more susceptible to the effects of pesticide exposure as a result of unusual exposure patterns and developmental immaturities. Transplacental transfer and lactational exposure are the pathways exclusive to the developing fetus and infant. Chlorpyrifos exposure is of special concern in this population because of its …

The Performance Predictive Effectiveness Of Two Personnel Assessment Profiles For Tennessee Extension County Directors, Wm. Herbert Byrd, Iii

Doctoral Dissertations

Leadership effectiveness is a complex phenomenon involving personality traits, learned and natural skills and abilities, and the resulting behaviors as leadership is performed within context. Because of leadership influences upon organizational outcomes, it is critical for an organization to identify job-specific leadership indicators, to recognize potential leaders, and to recognize the absence of desirable traits in existing leadership. This descriptive study explored the relationships between performance and leadership traits for county directors, the first-line administrative personnel in the University of Tennessee Extension. Performance appraisal scores were compared to items measured in a Managerial Assessment of Proficiency (MAP^TM) and …

Doctoral Dissertations

In this dissertation, the systematics of the [pi]h₁₁/₂ [tensor] [nu]h₁₁/₂ and [pi]h₁₁/₂ [tensor] [nu]s₁/₂ isomeric configurations were studied for the odd-Z, N = 77 isotones near the proton drip line. The isomeric decays in ¹⁴⁰Eu, ¹⁴²Tb, ¹⁴⁴Ho and ¹⁴⁶Tm were measured by means of X-ray, [gamma]-ray and charged particle spectroscopy at the Recoil Mass Spectrometer at the Holifield Radioactive Ion Beam Facility (HRIBF) at Oak Ridge National Laboratory (ORNL). The spin and parity of I[pi] = 8⁺ and 5⁻ were deduced for the isomers in ¹⁴⁰ Eu and ¹⁴²Tb. New decay schemes were established, and the half-lives of the 8⁺ …

A Watershed Classification System Based On Headwater Catchments In Great Smoky Mountains National Park, Tennessee-North Carolina, Martin Dietrich Lafrenz

Doctoral Dissertations

Headwater areas in the southeastern U.S., as well as elsewhere, have received little attention from researchers, even though headwater catchments comprise over 70% of the land area in the southeastern highlands. The small, low-order streams that drain these catchments are greatly affected by hillslope processes within their watersheds. As such, there exists a strong link between upland landscape history and a headwater stream’s condition, including its channel morphology, habitat, and water quality. I employ this tight connection between landscape-scale attributes and reach-scale morphology in order to develop a headwater catchment classification system for Great Smoky Mountains National Park that describes …

Studies On The Role Of Specific Residues Of The Saccharomyces Α-Factor Pheromone Receptor (Ste2p) In The Inactive And Active State, Yong-Hun Lee

Doctoral Dissertations

G protein-coupled receptors (GPCRs) are a class of integral membrane receptor proteins that are characterized by seven-transmembrane (7TM) domains connected by intracellular and extracellular loops, an extracellular N-terminus, and an intracellular C-terminus. To date more than 1000 GPCRs have been identified, and these proteins recognize neurotransmitters, sensory molecules and chemotactic agents. These receptors are involved in the control of many aspects of metabolism and play important roles in diverse processes such as pain perception, growth and blood pressure regulation, and viral pathogenesis. Therefore, these proteins became important target for therapeutic agents and recent reports indicate that nearly 40% of drugs …

Differential-Algebraic Approach To Speed And Parameter Estimation Of The Induction Motor, Mengwei Li

Doctoral Dissertations

This thesis considers a differential-algebraic approach to estimating the speed and rotor time constant of an induction motor using only the measured terminal voltages and currents. It is shown that the induction motor speed satisfies both a second-order and a third-order polynomial equation whose coefficients depend the stator voltages, stator currents, and their derivatives. Further, it is shown that as long as the stator electrical frequency is nonzero, the speed is uniquely determined by these polynomials. The speed so determined is then used to stabilize a dynamic (Luenberger type) observer to obtain a smoothed speed estimate. With full knowledge of …

Thermal And X-Ray Analysis On The Origin Of Double Melting Phenomena Of Poly(L-Lactic Acid) Films, Xiaoyun Ling

Doctoral Dissertations

Thermal analysis is one of the most commonly used techniques to characterize the structure and properties of semicrystalline polymers. Unfortunately, the interpretation of thermal events is not always straightforward, but can be quite complicated. However, the complexity involved is often overlooked, leading to erroneous or, at least, questionable results and interpretations. In the present study we carry out an extensive investigation of the thermal behavior of poly(L-lactic acid), PLLA, films prepared under a wide range of crystallization conditions, including isothermal and non-isothermal crystallization from both the glassy state and the melt. The primary techniques used were differential scanning calorimetry (DSC), …
