Optimal Sampling Paths For Autonomous Vehicles In Uncertain Ocean Flows, Andrew J. De Stefan

Dissertations

Despite an extensive history of oceanic observation, researchers have only begun to build a complete picture of oceanic currents. Sparsity of instrumentation has created the need to maximize the information extracted from every source of data in building this picture. Within the last few decades, autonomous vehicles, or AVs, have been employed as tools to aid in this research initiative. Unmanned and self-propelled, AVs are capable of spending weeks, if not months, exploring and monitoring the oceans. However, the quality of data acquired by these vehicles is highly dependent on the paths along which they collect their observational data. The …

Data Multiplexing In Vector Acoustic Communication: System Design And Experiments, Erjian Zhang

Dissertations

Acoustic particle velocity channels, which are vector components of the acoustic field, have been recently explored to achieve communication purposes underwater. Vector sensors and transducers that can utilize acoustic particle velocity channels have compact multichannel designs, which are perfect for compact size underwater platforms. In this dissertation, an underwater acoustic multiple-input multiple-output (MIMO) communication system featuring orthogonal frequency division multiplexing (OFDM) and frequency shift keying (FSK) modulation is discussed. By transmitting multiple independent data streams simultaneously over several channels within the same bandwidth, the proposed MIMO system increases the transmission rate. A variety of components of the system such as …

Impact Of The Bar Code Medication Administration (Bcma) System On Medication Administration Errors, Mary P. Davis

Dissertations

Medication errors are the second most frequent cause of injury among all types of medical errors (Leape, et al., 1991). Of concern to nursing practice, medication administration errors (MAE) are second only to ordering errors (Bates, Cullen, et al., 1995). The introduction of information technology designed to promote safe medication practice, such as the Bar Code Medication Administration (BCMA) system, offers new opportunities for reducing MAE. BCMA was developed to improve patient safety, improve documentation of medication administration, decrease medication errors, and capture medication accountability data. The overall goal of this study was to evaluate the impact of BCMA on …

Organic Buildup And Residual Blood On Clean Infant Stethoscopes Used In Maternal-Infant Areas, Jan Marie Nick

Dissertations

Since the mid 1980s, health care workers have attempted to eliminate contact with blood and other body via primary or secondary exposure. At delivery, stethoscopes used on newly born infants come in direct contact with blood and body fluids from the skin of the infant. If contaminants such as blood and body fluids still remain on stethoscopes despite cleaning, an environmental risk may exist.

Using a naturalistic setting, a non-experimental, two group post-test design was implemented to investigate the occurrence of organic buildup and residual blood on clean stethoscopes used on infants in the delivery and/or nursery areas. Eleven hospitals …

Enablers And Barriers Influencing African American Administrators’ Career Advancement At Predominantly White Institutions Of Higher Learning, Larry Webster

Dissertations

Many Predominantly White Institutions (PWIs) of higher learning do not have enough African Americans to lead their institutions in curriculum development, mentoring, recruitment, and governance (Reyes & Rios, 2005). Previous studies have attributed the modest representation of African American administrators to systemic barriers impeding the recruitment and advancement of African Americans at PWIs of higher learning (Jones, 2007; Perna, Gerald, Baum, & Milem, 2007). Ideally, the administrative leadership at PWIs of higher learning would adequately represent—ethnically and racially—its student population (Higgs, 2014). Levin, Walker, Haberler, and Jackson–Boothby (2013) suggest minimal progress in hiring African American administrators at PWIs of higher …

The Development Of Thad Jones’ Arranging/Scoring Style: A Comparative Study Of Six Works For Large Jazz Ensemble, Chang Su

Dissertations

This dissertation examined and compared six pieces for large jazz ensemble composed and arranged by Thad Jones. The analyses focused on Jones’ arranging and scoring techniques developed through three distinct periods of his career. In Jones’ early period, his arranging style showed influences from the Count Basie Orchestra as evidenced in blues vocabulary, call-and-response between saxophones and brass, and the form and structure of the arrangements. In his middle period, he explored symphonic sounds, suite-like forms, and elements from rock-jazz and funk-jazz music. In his late period, a more comprehensive development of tension and release guided his arranging. The vacancy …

Seductive Details In Educational Materials: Exploring Attention Distraction Using Eye-Tracking, Matthew A. Swaffer

Dissertations

Current advances in technology allow for a great deal of learning intervention materials to be designed by teachers. An active body of research is being conducted on how information is processed from these materials which are often created using electronic media. The design of these materials often includes interesting but irrelevant details which may detract from learning. These are termed “seductive details” and the impact of these inclusions in learning materials is not yet fully understood. Developing a better understanding of what factors play a role in the damaging effects of seductive details can help in the design of learning …

Values In Evaluations Of Maternal And Child Health Programs, Erica Lynn Dodds

Dissertations

Values are a central component in evaluation and are prominently discussed in evaluation theory, but relatively little is known about how they are used in practice. The theory-practice gap in evaluation may cause unsound evaluation practice or irrelevant or impractical evaluation theory. However, little is known about this gap as it relates to values and valuing. Failing to take certain values into account in an evaluation risks reinforcing the status quo to the detriment of vulnerable populations, so identifying how the theory-practice gap plays out in the use of values is important.

This study focuses on the maternal and child …

A Phenomenological Investigation Of Women’S Infertility And Miscarriage Grief Experiences, Tristan Mcbain

Dissertations

Infertility and miscarriage are reproductive losses that often produce grief reactions in affected women. This phenomenological study investigated the grief experiences of infertility and miscarriage through the ambiguous loss and disenfranchised grief frameworks in order to better understand both the obscurity of reproductive loss and how the resulting grief may be invalidated.

Sixteen women volunteered to participate in this study and each fell into one of the following three categories: women affected by infertility without miscarriage (4); women affected by miscarriage without infertility (4); and women affected by infertility and miscarriage (8). A phenomenological hermeneutic approach was utilized to uncover …

Deliberation For Devolution In The Public Sphere: A Case Study From Pakistan, Beenish Kulsoom

Dissertations

Genuine democratic deliberation on design of institutional rules is possible only when the state apparatus and political and civil society are engaged in communicative interexchange, exchanging ideas, and speaking in a language understood and accepted by all others. Moreover, in such an exchange the interlocutors do not hold back their thoughts to achieve strategic control in order to subvert the communicative engagement. The deliberative theory of democracy advocates communicative engagement between state and society actors that results in institutional rules that are accepted by all.

The advocates of the theory of deliberative democracy argue that while the state is the …

Validation Of The Ask-Asd In A Sample Of Parents, Teachers, And Medical Students, Laura K. Hansen

Dissertations

Autism spectrum disorder (ASD) is a neurodevelopmental disorder that begins in childhood and manifests in social communication impairment and restricted, repetitive behaviors (American Psychiatric Association, 2013). Although accurate information about ASD is available through a variety of sources, this access to information may not translate into increased knowledge in parents, teachers, and medical professionals. A Survey of Knowledge of Autism Spectrum Disorder (ASK-ASD) was initially established as a reliable, valid measure of perceived and actual knowledge of ASD (Hansen, 2015). The current study evaluated the psychometric properties (i.e., factor structure, reliability, and validity) of the ASK-ASD in a sample of …

The Underlying Psychophysiology Of Pedophilic Disorder And The Implications For Treatment Approaches, Tonise Florexil

Dissertations

Sexual crimes are a persistent and significant social dilemma that continues to plague our society (Lee, Jackson, Pattison, & Ward,2002). Past research has made considerable advancements in terms of the types of interventions that clinicians can utilize when they work with individuals who have a history of child sexual offenses. However, current literature lacks an understanding of the risk factors that influence the development of Pedophilic Disorder. A history of sexual trauma also affects families. The children of traumatized individuals have more adjustment difficulties than their counterparts who did not have a parent(s) with a sexual trauma history. This clinical …

An Exploratory Investigation Into The Role Of Evaluation Theory In Evaluative Thinking, Lyssa Wilson Becho

Dissertations

The field of evaluation generally agrees that evaluation theory is important. Evaluation theorists and scholars have written prolifically about the role of evaluation theory in practice. However, the empirical literature associated with how and why evaluation theory is important is still emerging. In particular, how evaluation theory fosters high quality evaluation practice through transparent logical reasoning, attention to values and valuing, and contextual responsiveness, and how these inform evaluative thinking are understudied phenomena in the field.

This study intends to provide insights into the relationship between evaluation theory and evaluation practice to answer two major research questions. The first research …

From The Boots On The Ground: A Comparison Of The Attitudes And Beliefs Of Military Members And Mental Health Professionals Regarding The Moral Injury Construct, Karis L. Callaway

Dissertations

An increasing amount of research conducted in recent years indicates that, in addition to Posttraumatic Stress Disorder, moral injury is a key concept to recognize when considering the deployment experiences of service members. Although related to Posttraumatic Stress Disorder, which is a fear-based mental health diagnosis, moral injury is a distinct concept. It acknowledges the possible prolonged negative psychological, social, and spiritual consequences that may occur after experiences that challenge and transgress one’s deeply held moral beliefs. Events such as perpetration of harm, failing to protect or prevent harm, and witnessing or learning about distressing acts committed by influential others …

This uncertainty has also left lingering impacts on economic growth, especially in developing countries that have weak institutional mechanisms. This study examines how banking supervision and regulatory reforms are determined in the cross-national context of advanced and developing countries. Using time series, cross-sectional data on 180 countries over a period of 12 years (1999-2011), the purpose is to explore the roles of exposure of financial crisis, trade …

A Cumulative Summation Nonparametric Multiple Stream Process Control Chart Based On The Extended Median Test, Austin R. Brown

Dissertations

In statistical process control applications, situations may arise in which several presumably identical processes or “streams” are desired to be simultaneously monitored. Such a monitoring scenario is commonly referred to as a “Multiple Stream Process (MSP).” Charts which have been designed to monitor an MSP typically monitor the means of the streams through collecting samples from each stream and calculating some function of the sample means. The resulting statistic is then iteratively compared to control limits to determine if a single stream or subset of streams may have shifted away from a specified target value. Traditional MSP charting techniques rely …

Achieving Musical Peak Performance: The Impact Of An Online Self-Efficacy And Performance Anxiety Management Program Based On Maslow’S Hierarchy Of Needs, Melynie Joy Campbell

Dissertations

Every musician should be encouraged to strive for peak performance; however, many musicians do not know how to achieve it. Although there is a significant amount of research done on music cognition, music therapy, and musical behavior, the research that aims to expose the inner workings of the performer’s brain is still in its infancy. In the field of Sports Performance Psychology, there have been many performance-based studies designed to discuss this idea among athletes; however, to date, there has not been a correlation for how to attain peak performance results among musicians. To bridge the relationship between the theories …

“We’Re Going To Be Figuring It Out Forever”: Testimonios Of Brown Women And Their Experiences Self-Authoring Their Brownness In Graduate School, Reyna Monique Anaya

Dissertations

Race, a socially constructed idea designed to maintain the power and privilege of Whiteness and the colonial and economic exploitation of Black/Brown-identified people in the United States (Quiros & Araujo Dawson, 2013), has a direct impact on the ethnic identity development and self-authorship of Brown people (i.e., Latina/os, Chicana/os, Hispanics, etc.). This inquiry uncovers the testimonios of five Brown women participants and their continued ethnic identity and self-authorship development as first-generation students in graduate school. From a critical, cultural, constructivist lens and blend of testimonio (Reyes & Curry Rodriguez, 2012) and collage inquiry (Butler-Kisber, 2007), this research applied a borderlands/Mestiza …
