Teaching Music Theory In The Traditional Wind Band Rehearsal: A Rationale, Survey Of Materials, And Recommendations, Eric Lynn Harris

Dissertations

Band programs in today’s schools are facing pressures unheard of in the early days of the public school band movement. While budget limitations have always been a part of the public school dilemma, never before have directors been forced to fight so hard for the very existence of their programs. School administrators facing district, state, and federal testing pressures are spending more and more of the annual budget in an attempt to raise test scores. This means programs in the arts and even athletics are being greatly reduced (and in some cases eliminated) in school systems across the country. To …

Beholding The Beauty Of Self: The Psychological Integration Of The Afrocentric-Self Among African-American Females Socialized In A Eurocentric Aesthetic, Donna Lynn Cook Phd

Dissertations

Self-esteem and body image disturbances prominently figure into many physical and psychological health disorders such as depression, eating disorders, anxiety disorders, and chemical dependency. In Euro-American culture, media images of femininity and physical attractiveness reinforce generally held perceptions of the idealized female beauty as tall, white, slender, and often blond and blue eyed. The physical morphology of African-American women does not genetically "fit" this westernized standard of beauty with implications for their mental health. The socialization of African-American women in a culture that embraces a different ethnic standard of beauty influences their perceptions of how physically attractive they see themselves. …

Defining Health And Health-Related Behaviors Following A Near-Death Experience, Suzanne C. Robertson Phd

Dissertations

While broad categories of health and influences on definitions of health have been identified, the process through which adults define and re-define health has not been researched. The purpose of this study was to investigate the process of defining health and appropriate health-related behaviors following a near-death experience (NDE) as an adult and to articulate a grounded theory of decision-making. Five men and 15 women from the United States and United Kingdom were interviewed and the data were analyzed using the constant comparative method. The basic social process was I Still Had to Go Through the Process of Understanding. Understanding …

The Viability Of Is Enhanced Knowledge Sharing In Mission-Critical Command And Control Centers, Sameh A. Sabet

Dissertations

Engineering processes such as the maintenance of mission-critical infrastructures are highly unpredictable processes that are vital for everyday life, as well as for national security goals. These processes are categorized as Emergent Knowledge Processes (EKP), organizational processes that are characterized by a changing set of actors, distributed knowledge bases, and emergent knowledge sharing activities where the process itself has no predetermined structure. The research described here utilizes the telecommunications network fault diagnosis process as a specific example of an EKP. The field site chosen for this research is a global undersea telecommunication network where nodes are staffed by trained personnel …

On Mitigating Distributed Denial Of Service Attacks, Zhiqiang Gao

Dissertations

Denial of service (DoS) attacks and distributed denial of service (DDoS) attacks are probably the most ferocious threats in the Internet, resulting in tremendous economic and social implications/impacts on our daily lives that are increasingly depending on the wellbeing of the Internet. How to mitigate these attacks effectively and efficiently has become an active research area. The critical issues here include 1) IP spoofing, i.e., forged source lIP addresses are routinely employed to conceal the identities of the attack sources and deter the efforts of detection, defense, and tracing; 2) the distributed nature, that is, hundreds or thousands of compromised …

A new authentication model for high-value transactions in cluster-based MANET is also designed in MANS system. This model is motivated by previous works but try to use their beauties and avoid their shortcomings, by using threshold sharing of the certificate signing key within each cluster to distribute the certificate services, and using certificate chain and certificate repository to achieve better scalability, less …

Automatic Modulation Classification Of Communication Signals, Zaihe Yu

Dissertations

The automatic modulation recognition (AMR) plays an important role in various civilian and military applications. Most of the existing AMR algorithms assume that the input signal is only of analog modulation or is only of digital modulation. In blind environments, however, it is impossible to know in advance if the received communication signal is analogue modulated or digitally modulated. Furthermore, it is noted that the applications of the currently existing AMR algorithms designed for handling both analog and digital communication signals are rather restricted in practice. Motivated by this, an AMR algorithm that is able to discriminate between analog communication …

Selected Problems Of Inference On Branching Processes And Poisson Shock Model, Satrajit Roychoudhury

Dissertations

This dissertation explores the development of statistical methodology for some problems of branching processes and poisson shock model.

Branching process methods have become extremely popular in recent days. This dissertation mainly explores two fundamental inference problems of Galton-Watson processes. The first problem is concerned with statistical inference regarding the nature of the process. Two methodologies have been developed to develop a statistical test for the null hypothesis that the process is supercritical versus an alternative hypothesis that the process is non-supercritical. Another problem we investigate involves the estimation of the 'age' of a Galton-Watson Process. Three different methods are discussed …

Healthy Lifestyles Of Adults In A Work Setting, Kim Schafer Astroth

Dissertations

Nurses have a key role in promoting healthy lifestyles to reduce incidence of disease in adults. Since the 1980¿s, researchers have recognized readiness as a key component of adopting healthy lifestyle change. Prochaska¿s transtheoretical model, which contains readiness, or stage of change, served as the theoretical framework for the current study. The purpose of this study was to test an exercise behavior model, and in so doing: (a) compare the concurrence rates of exercise stage of change classifications obtained from the four selected exercise stage of change self-report measures; and (b) determine the relative strength of the predictive factors of …

Four research questions guided this study: 1) How do individuals with autism and the people who support them describe their relationship? Specifically, how was the relationship established, how has it changed, what are the benefits and challenges, what works and what does not, and how is the relationship maintained? 2) From the perspective of both the individuals with autism and the supporting individuals, how do their relationships provide support for the individual with autism? 3) How does the mode of communication influence …

Unintended Consequences In Public Policy: Formulation And Implementation Of Michigan’S Safe Delivery Of Newborns Law, Anne Julie Hacker

Dissertations

It is generally believed that social policy is the result of careful research and planning on the part of officials. Yet there often exists a gap between theformulation and implementation of many social policies. This gap brings with it conflict, which in turn may result in unintended consequences. Theseconsequences may be so antithetical to the formulators' original intent as to make the policy implementation paradoxical.

This qualitative research study examines the ambiguities, challenges, or boundaries that policy formulators placed on practitioners responsible for implementing Michigan's Safe Delivery of Newborns Act and that ultimately created unintended consequences indicative of a public …

The first two essays analyze the cross-sectional returns on the U.S. stock market by emphasizing the dynamics of risk loadings. The third essay studies the impact of a tight monetary policy on weak currencies during financial crises by examining the time-varying relationship between interest rates and exchange rates.

Motivated by the pricing errors found in small size and low book-to-market ratio portfolios in the Fama-French three-factor model, the first essay proposes a time-varying four-factor model. As small size and low book-to-market ratio firms are more …

Effects Of Anxiety Induction On Facial Recognition Skills Within A Sample Of Adult Victims Of Childhood Abuse, Kathryn M. Bell

Dissertations

Although it is well established that interpersonal victimization can lead to affect regulation problems, less is known about the extent to which childhood victimization impairs facial recognition skills. Most studies exploring this relationship have focused on emotion recognition (ER) in physically abused and neglected children. The degree to which these ER problems apply to sexual victimization and extend into adulthood is yet unknown. The current study examined the impact of physical and sexual childhood abuse on adult ER skills under a heightened arousal condition in 104 women with varying childhood victimization experiences. The relationship between childhood victimization and ER skills …

Characterization Of Membrane Potentials In Vascular Smooth Muscle Of Hagfish, Lamprey And Trout, Prentiss Jones Jr.

Dissertations

The objective of this study was to characterize membrane potentials in systemic arteries of Pacific hagfish, Eptatretus stouti, Rainbow trout, Onchorhyncus mykiss, and Sea lamprey Petromyzon marinus. Previous studies have characterized membrane potentials in piscine tissue. However, these studies utilized non-vascular tissues such as cardiac muscle and skeletal muscle (69, 161). Characterization of membrane potentials in fish vasculature is without precedent in the literature. The hypothesis of this study was that membrane potentials in fish vascular smooth muscle differ little between species when comparable vasculature is evaluated.

An Evaluation Of Intraverbal Training And Listener Training For Teaching Categorization Skills, Anna Ingeborg Petursdottir

Dissertations

Behavioral language interventions, such as those employed in early and intensive behavioral intervention (EIBI) programs, target both expressive and receptive language skills. Skinner's (1957) analysis of verbal behavior provides a framework for analyzing expressive and receptive language in terms of stimulus control and reinforcement history. From this perspective, different expressive language programs target different verbal operants, such as tacts, intraverbals, and echoics , whereas most receptive language programs target a type of listener behavior that may be referred to as manded stimulus selection (Michael, 1995). Although EIBI curricula (e.g., Maurice, Green, & Luce, 1996; Leaf & McEachin, 1999) have frequently …

Markov Chain Monte Carlo Methods For Regression Splines With A Penalized Acceptance Ratio, David Keith Stamps

Dissertations

An increasingly popular method for fitting complex models, particularly with a hierchical structure involvese the use of Markov Chain Monte Carlo simulation. Within a Bayesian framework, two major strategies are Gibbs sampling and Metropolis-Hastings methods. Recent research in the area of MCMC methods has witnessed the emergence of modeling efforts which permit the movement of the chain across models of varying dimensions. When properly constructed, such Markov chains converge to the joint posterior distribution of the parameters to be estimated, making Bayesian averaging an attractive option after convergence has occurred. With this transdimensional methodology, the Bayesian averaging process takes place …

The Effects Of Rumination On Problem-Solving Self-Efficacy And Self-Efficacy For Controlling Upsetting Thoughts In The Context Of Depressive Symptoms, Christina Marcia Gilliam

Dissertations

Two cognitive variables that are of interest in their role in depression are self-efficacy and rumination. Self-efficacy refers to individuals¿ own appraisal of their ability to successfully accomplish a domain of tasks (Bandura, 1977). Rumination, as defined by Response Styles Theory (Nolen-Hoeksema, 1991), refers to the process of repetitively and passively thinking about negative emotions, consequences, and symptoms of distress. Although the relationship between these two constructs and depression has been examined in both experimental and correlational studies, there has been minimal research on the relationship between self-efficacy and rumination among depressed individuals. The present study was intended to replicate …

The Power Of "Estudentprotest:" A Study Of Electronically-Enhanced Student Activism, James Patrick Biddix

Dissertations

Both student activism and Internet use by students are among the fastest growing variables in national reports of student engagement (Astin, 2004; Levine & Cureton, 1998b). This study introduces the term estudentprotest to describe how contemporary student activists use information and communication technologies (ICTs) for protest. A sequential mixed methods design (Creswell, 2003) was utilized. This approach involved obtaining statistical information from a sample for descriptive and outcome analyses, using the results to suggest nodes for an investigation of social networks, and finally interviewing individuals to explore those results in more depth. This study found that today¿s student protests begin …

Biogeography Of Buarremon Brush-Finches (Aves, Emberizinae): Integrating Ecology, Evolution, And Systematics, Carlos Daniel Cadena

Dissertations

Ecological and historical approaches to studying species¿ geographic ranges have yet to be unified. Ideal scenarios for integrating ecology with evolutionary biology in biogeography are those where contemporary ecological interactions may have influenced species¿ distributions historically, driving the evolution of ecological niches. I focused on understanding the origin of elevational distributions of species, and specifically on the role of interspecific competition in the origin of complementary elevational ranges. To test hypotheses about the origin of elevational distributions, I followed a combined approach involving molecular phylogenetics, phylogeography, population genetics, and ecological niche modeling. I focused on Buarremon torquatus and B. brunneinucha …

Image Segmentation By Energy And Related Functional Minimization Methods, Eric Hudson Mason

Dissertations

Effective and efficient methods for partitioning a digital image into image segments, called ¿image segmentation,¿ have a wide range of applications that include pattern recognition, classification, editing, rendering, and compressed data for image search. In general, image segments are described by their geometry and similarity measures that identify them. For example, the well-known optimization model proposed and studied in depth by David Mumford and Jayant Shah is based on an L₂ total energy functional that consists of three terms that govern the geometry of the image segments, the image fidelity (or closeness to the observed image), and the prior …

Is Rumination General Or Specific To Negative Mood States? The Relationship Between Rumination And Distraction And Depressed, Anxious, And Angry Moods In Women, Jessica Lauren

Dissertations

Rumination has been found to play a role in negative affect by either maintaining or increasing depressive, anxious, and angry moods, whereas distraction has been found to decrease these negative moods. This experiment tested the hypothesis that the effect of rumination occurs across mood states and is not specific to one type of negative mood, using both Nolen-Hoeksema¿s Response Styles Theory (RST; 1991), and Bower¿s Associative Network Theory (1981; ANT). The impact of rumination and distraction on depressed, anxious, and angry mood states were examined in 90 women at the University of Missouri ¿ St. Louis. Participants were randomly placed …

Using a two-stage, mixed-method strategy of inquiry that follows symbolic interactionism, this study explores professional development/faculty development (PD/FD) practices and perspectives in the university setting. Four Midwestern universities, two public and two private, provided the setting for the research. The primary purpose of this study was to answer the question: What is the experience university professors have with professional development/faculty development (PD/FD). The literature presents many studies for K-12 and community college faculties; however, there is a need to study the topic within the university subculture. On-campus PD/FD programs offer faculty opportunities to improve and expand their teaching methodologies yet …

Nurse Practitioner Adoption Of Clinical Innovations, Rhoberta Jones Haley Phd

Dissertations

Adoption of clinical innovations by Nurse Practitioners (NP) is a complex phenomenon, rooted in personal values and influenced by challenges within health care environments. When clinical innovations are adopted or rejected by NPs, this decision has meaning for patients, NPs, health care agencies, and society. The decision controls the opportunity for patients to access a clinical innovation that could reduce morbidity and mortality, save money, and provide satisfaction related to the health care encounter. The purpose of the study was to increase knowledge about NP adoption of clinical innovations, particularly emotionally-laden clinical innovations. The lines of inquiry focused on what …

Exposure Of Nervous System Cells To Polychlorinated Biphenyls (Pcbs), Results In Alterations Of Neurotrophic Factor Expression, Gordon H. Gurley

Dissertations

Toxic insult by PCBs results in learning and memory deficits in humans. Alterations in expression of neurotrophic factors (NF) and/or their receptors have been linked to changes in learning and memory. How PCBs affect cognition is not known. We suggest that PCBs affect cognition by altering NF expression.

We exposed cultured C6 rat glioblastoma cells (an astrocyte cell-line) to medium containing PCB (Aroclor 1254 (10ppm)). Control cells were treated with dimethyl sulfoxide (DMSO) or regular medium. Enzyme-linked immunosorbent assays (ELISA) were used to determine glial cell-line derived neurotrophic factor(GDNF) and nerve growth factor (NGF) concentrations in all samples. We also …

Molecular Analysis Of The Effects Of Atrazine On Xenopus Laevis Frogs, Ronald Edward Celestine

Dissertations

Atrazine, the most commonly used herbicide in the U.S., has been implicated as one of the factors that may be causing the worldwide decline of amphibians. First, I examined effects of atrazine on laboratory raised Xenopus laevis tadpoles, treated from 5 days post fertilization to NF stage 65/66 with a concentrationof 25 ppb of atrazine. This study showed no significant difference in body weight, length and metamorphic rate.

Second, I used DNA microarrays to examine mRNA expression levels of genes in atrazine treated and control Xenopus laevis tadpoles. I found significant changes in gene expression levels of 18 genes. These …
