The Prehistory Of Fentress County, Tennessee: An Archaeological Survey, Jay Douglas Franklin

Doctoral Dissertations

This dissertation presents a synthesis of recent and ongoing archaeological investigations of the caves, rock shelters, and open air uplands of the Upper Cumberland Plateau of Tennessee. The primary working hypothesis of this research is that existing culture histories applied to this region are inadequate. Existing culture histories for Middle and East Tennessee were developed in adjacent regions, primarily lowland river flood plains. These culture histories have been boiler-plated onto the Cumberland Plateau even though comparatively little systematic archaeological research has actually been conducted in the region. Furthermore, upland regions, such as the Cumberland Plateau, have often been characterized as …

Peak Alpha Frequency: An Electroencephalographic Measure Of Cognitive Preparedness, Efthymios Angelakis

Doctoral Dissertations

Background.

Electroencephalographic (EEG) peak alpha frequency (PAF) has been shown to correlate with a variety of phenomena, including age, memory performance in healthy and demented individuals, different emotional states, schizophrenia, anxiety, recovery from stroke, cerebral blood flow (CBF) velocity, brain oxygenation, as well as acute administration of stimulant and nootropic substances. These studies have shown that PAF varies between healthy and clinical individuals, with the latter consistently having lower PAF. Moreover, PAF varies between healthy individuals, reflecting cognitive performance, with better performance being associated with increased PAF. Finally, PAF varies within individuals both between developmental stages and between different cognitive …

The Link Between Capital Structure And Product Market Competition: Theory And Evidence, Lee Greer

Doctoral Dissertations

The relationship between capital structure and product market competition is examined using a theoretical model and two econometric analyses. In an extension of Glazer (1994), a theoretical model is derived that allows a quantity leader and follower to issue debt and then twice play a sequential product market game, after which each firm must either repay its debt in full or go bankrupt. It is demonstrated that the follower maximizes operating profit irrespective of capital structure but that the levered quantity leader in every period produces more than the Stackelberg profit-maximizing level of output. As such, the industry characterized by …

Biological Affinities Of Archaic Period Populations From West-Central Kentucky And Tennessee, Nicholas Paul Herrmann

Doctoral Dissertations

The Green River Archaic period skeletal collections represent one of the largest regionally specific aggregate hunter-gatherer sample available for study. These collections have been the focus of numerous studies on paleopathology and paleodemography. Indian Knoll (15OH2) is the largest collection with over 1000 individuals. These burials were recovered from two primary excavations directed by Clarence B. Moore and the Work Progress Administration (WPA) in the first half of the nineteenth century. The WPA excavated numerous sites along the Green River and it’s tributaries resulting in additional skeletal collections from sites such as Barrett (15McL4), Carlston Annis (15BT5), Chiggerville (15OH1), Read …

Eeg Patterns Of Tbi Patients With Attention Deficits During Cognitive Tasks And Second Resting Baseline, Stamatina Stathopoulou

Doctoral Dissertations

According to previous research, different regions of the brain are activated when a person is required to use different types of attention like selective, alternating, focused, sustained and divided attention. The frontal, prefrontal and parietal areas especially in the right hemisphere, seem to be the most frequently activated areas. Little research has addressed differences in the electroencephalogram (EEG) between traumatic brain injured (TBI) patients, with different types of attentional deficits because of their injury, and normal population. This study focuses on differences in magnitude in five brain regions between TBI patients and normal population, during recording of one cognitive task …

The Effect Of Personality On The Spiral Of Silence Process, Kyoungtae Nam

Doctoral Dissertations

The study examines the effect of personality on the spiral of silence process. Despite the social-psychological nature of the spiral of silence theory, there has been little investigation on the relationship between personality and the spiral of silence process. In the current study, two personality constructs, independent/interdependent self-construal and right wing authoritarian personality, are examined to see how they affect a person’s willingness to speak out. In March through April 2002, 714 college students were surveyed. Three topics that were identified as highly controversial in the preliminary study were used in the final survey: abortion (n=238), affirmative action (n=234), and …

Data Visualization: Graphical Representation In The Evaluation Of Experimental Group Therapy Education Outcomes, Randall E. Basham

Doctoral Dissertations

Introduction: An important methodological consideration in the social sciences is the evaluation of the effectiveness of groups and specific group interventions. There is an increasing demand for service accountability in practice settings both in social services and public health services. Group services are rising as a practice modality. Emerging technology shows promise of providing the means for practitioners untrained in advanced research methods to gain useful information and improved decision- making capacities related to groups and group services. Computer based graphical representation of data patterns at multiple levels of analysis can provide the bases for data exploration and lead to …

An Empirical Analysis Of The Effect Of The Need For Closure On Materiality Thresholds Of Auditors, Cynthia M. Daily

Doctoral Dissertations

The purpose of this study is to identify the strengths of a specific motivator for judgment and decision-making, referred to as “need for closure” and determine how the strength of that motivator affects materiality judgments of auditors.

The extent to which auditors seek and process information prior to forming a judgment can have important consequences in the conduct of an audit. In this regard, psychology researchers have identified a personality characteristic—a motive for judgment and decision making—that influences the decision making process. This motive, referred to as the need for closure, pertains to the desire of individuals to clear …

Household Food Sufficiency Status And The Qualityof Children's Diets: An Analysis From The Continuing Survey Of Food Intakes By Individuals 1994-1996, 1998, Linda Lou Knol

Doctoral Dissertations

The relationship between food sufficiency and diet quality was explored among children 2-8 years of age living in households ≤185% poverty with 2-days of dietary recall data from 1994-96, 1998 Continuing Survey of Food Intakes by Individuals. Diet quality was assessed using measures of both adequacy and variety. Diet adequacy was measured by degree of adherence to age-specific daily serving recommendations for the 5 Food Guide Pyramid food groups and by intake of discretionary fat (grams) and added sugars (teaspoons). Variety was measured using the Healthy Eating Index Variety Score ( overall variety), the Dietary Diversity Score (among food group …

The Integrative Model Of Personality Assessment For Achievement Motivation And Fear Of Failure: Implications For The Prediction Of Effort And Performance, Mark Nathaniel Bing

Doctoral Dissertations

While both self-report (SR) and conditional reasoning (CR) measures of achievement motivation (AM) and fear-of-failure (FF) have been shown to be predictive of academic and organizational outcomes (James, 1998; Spangler, 1992), substantial criterion variance is often left unaccounted for by either measurement system when used in isolation. The current work proposes a new, theoretical model of AM and FF created by integrating information on explicit cognitions gathered from SR with information on implicit cognitions gathered from CR. This “integrative model” of assessment provides an enhanced understanding of the approach-avoidance conflicts people experience when they are faced with challenging tasks. Predictions …

Weekly scanner data on the purchases of canned-tuna in Knoxville, Tennessee collected by Information Resources, Incorporated (IRI) were used for the estimation of the degree of market power and strategic-price responses. Four canned tuna brands were investigated including the three leading brands, Starkist, Chicken of the Sea, and Bumble Bee, and the competitive small-market share brands aggregated into Allother.

There are two empirical parts. The first part focuses on estimation of the degrees of market power and strategic-price …

Toward A Dynamic Model Of State Choice: Gains Pursuit Debate And The World System, Soo-Lyon Yon

Doctoral Dissertations

The purpose of my dissertation is to challenge the mainstream tradition of discourse in the field of international relations with regard to the world system and gains pursuit which has been framed by two significant theoretical perspectives: realism and neoliberalism.

In my dissertation, I established a theoretical linkage between the gains pursuit debate and the dynamics of the world system. The problem of absolute and relative gains divides two of the most influential approaches to international relations theory: realism and neoliberalism. However, these dichotomized approaches to gains pursuit assume a fixed (or static) view of the world system based on …

Using a document analysis method based on principles of qualitative research, 504 advertisements for the Internet and Internet-related products appearing in Time magazine during 1995-2000 were examined. The analysis focused on identifying categories of message strategies and technological themes used in the ads and examining the changes in the use of the message strategies and technological themes.

Careful analysis revealed that the number of ads promoting the …

An Exploratory Study On The Relationships Among Electorate's Voting Behavior, Party Identification, Personal Values, And Demographic Characteristics, Kuan-Shun Chiu

Doctoral Dissertations

This study was proposed to examine if there existed significant differences in voters' party identification and voting behavior due to gender, race, age, income, education and personal values.

The sample was chosen from eligible voters in Florida. Of the 1500 questionnaires managed, 161 were identified as useable. The sample was representative of the results of 2000 presidential election in Florida with respect to voters' gender, race, income, and voting choice by party identification. Statistical techniques used were ANOVAs, Chi-square statistics, factor analysis, and logistic regression.

This study demonstrates how personal values may be associated with demographic characteristics to create a …

An Expectancy-Value Analysis Of Web Gratifications, Meiling Shih

Doctoral Dissertations

The present study explored the mechanisms directing Web usage decisions to determine more reliable estimates of the importance of various influences involved.

A Web-based survey was administered to respondents who voluntarily participated by responding to a message posted to selected Internet discussion groups. Exploratory factor analysis and covariance structure model were employed to examine the relationships between attitude, expectancies, motivation, intention, and usage regarding the Web.

Research evidence spoke strongly against univariate or bivariate motivational schemes. In addition to surveillance and diversion functions that have been found in traditional mass media, the Web also provided two unique qualities, utility and …

Personal Identification Based On Patterns Of Missing, Filled, And Unrestored Teeth, Bradley Jacob Adams

Doctoral Dissertations

Dental comparison of antemortem and postmortem records provides one of the best avenues for establishing personal identification in the forensic sciences. The types of antemortem dental evidence are extensive (including treatment notes, odontograms, radiographs, casts, photographs, etc.) and in many instances a positive identification can be established strictly on a dental comparison. Perhaps the best form of antemortem dental evidence is the radiograph, which provides a detailed odontoskeletal record of a specific individual at a specific point in the past. Unfortunately, antemortem radiographic evidence is not always available during forensic comparisons. For example, at the U.S. Army Central Identification Laboratory, …

Per Mile Emissions Taxes And Lump Sum Emissions Taxes: A Comparative Study Using A Mathematical Approach To Demand Estimation, Robert Paul Culp

Doctoral Dissertations

The primary purpose of this study was to compare two common emissions based taxes by implementing a mathematical approach to consumer demand estimation for new vehicles. The model developed allows the researcher to derive demand from observed firm output and market prices using assumptions about firm and consumer behavior, and market structure. The advantage of this revealed demand approach is that it does not require the specification of the consumer’s utility function or any firm’s production function. In addition, the own price and cross price elasticities of vehicle demand are determined without statistical regression.

The model developed in this paper …

Civic Engagement In The Cyberspace Era: A Study Of A Local Cybergroup, Gay Henry Lyons

Doctoral Dissertations

The purpose of this study was to explore the issue of participation and civic engagement through the investigation of cyberspace as public space. The research systematically studied the development, nature, operation, and impact of k2k, a local cybergroup based in Knoxville, Tennessee. While the emergence of cyberspace as public space is no panacea for the ills of democracy in America, it is clearly a potential antidote to counter the more virulent dimensions of civic disengagement in the United States. However, for a cybergroup to serve as an antidote to civic disengagement, the participants must move beyond electronic discourse into the …

A Phenomenological Study Of The Experience Of Travel, Norris Lee Smith

Doctoral Dissertations

To describe and gain an understanding of the experience and meaning of travel, ten participants were asked to “tell me about some times you’ve traveled that stand out to you.” These interviews were non-structured, and the ensuing dialogue served as data for a research project concerning first-person accounts of the lived experience of travel. Once completed, each interview was typed and underwent hermeneutic analysis within the context of an interpretive research group. Results of thematic analysis revealed that travel was described as a movement away from “home,” a venturing out, which was characterized by participants in figure-ground terms. For this …

Relationships Between A Quaternary Model Of Psychological Type Processes And Defense Mechanism Clusters, Kathryn Elizabeth Kelly

Doctoral Dissertations

This study examined the relationships between two psychological type dimensions (Extraversion-Introversion and Thinking-Feeling) and defense mechanism preferences. Psychological Type Theory was used as a conceptual framework for the generation of hypotheses. Specific hypotheses between the two psychological type dimensions and defense mechanism preferences were tested. Further, Extraversion-Introversion and Thinking-Feeling were combined, resulting in the formation of a quaternary personality model consisting of four groups (Introverted Thinking, Introverted Feeling, Extraverted Thinking, and Extraverted Feeling). Hypotheses that certain quaternary groups would display specific relationships with defense mechanism preferences were tested. To test hypotheses, 223 university students were administered the Myers-Briggs Type Indicator …

Financial Performance Of Insurance Companies Following Initial Public Offerings, Kulkanya Napompech

Doctoral Dissertations

The quality of insurance companies is a very significant societal issue. Policyholders pay premiums assuming indemnity of their potential losses. It is essential that an insurer be able to meet its contractual obligations when a loss occurs. An initial public offering provides an infusion of capital and an expansion of resources available to a firm. Thus, the objective of this study is to examine the financial and operating impacts of initial public offerings during 1980–2000 on insurance companies.

Chapter 2 examines changes in operating performance of property/casualty insurance companies following initial public offerings. I find that following initial public offerings, …

Asp -Pricing: A Black -Scholes Option Pricing Formulation, Chaitanya Singh

Doctoral Dissertations

The Applications Service Provider (ASP) arrangement has engendered a revolution in the area of corporate information technology (IT) by transforming software from a packaged off-the-shelf product to an on-line virtual service.

The focus of this study is to establish a sound mathematical foundation for evaluating software rental agreements (embedding exit flexibility) by incorporating a real options framework (based upon the Black-Scholes approach) into the traditional capital budgeting technique. The static discounted cash flow or net present value analysis may not adequately serve as a ‘barometer’ of outsourcing value due to its inherent weaknesses. On the other hand, the options approach …
