A Microbiomic Approach To The Characterization Of The Impacts And Influences Of Viral, Bacterial, And Harmful Algal Bloom Toxins On The Bottlenose Dolphin, Corey David Russo

Dissertations

As apex predators that display high site fidelity Tursiops truncatus (bottlenose dolphin) are indicators of marine ecosystem health. Bottlenose dolphins, additionally, display pathogenesis and immune response similar to that of humans. Humans and coastal bottlenose dolphins, in particular, are constantly exposed to the same industrial, agricultural and domestic toxins and pathogens, contaminants and pollutants. Thus, studies on the bottlenose dolphin are also valuable in bridging the gap between ocean and human health. Bottlenose dolphins are susceptible to viral bacterial and toxin infection. Infection in the bottlenose dolphin manifests itself in the form of mass stranding events, unusual mortality events, chronic …

Moving Words/Motion Pictures: Proto-Cinematic Narrative In Nineteenth-Century British Fiction, Kara Marie Manning

Dissertations

In the broadest sense, this project is about nineteenth-century narrative texts and optical toys, or those devices that were originally created to demonstrate scientific knowledge related to vision but that would also become popular for home and public consumption. I argue that nineteenth-century British writers borrowed and adapted the visual effects of such toys, making fiction as participatory as the toys themselves in the development of image culture and the viewing practices that would become necessary for the production and dissemination of cinema in the early twentieth century. Narrative fiction, then, should be considered along with the other precursors of …

Theatrical Elements In Toru Takemitsu's Voice And Karlheinz Stockhausen's Zungenspitzentanz, Brielle Marie Frost

Dissertations

The flute has long been recognized for maintaining avian or mythological roles within music. The repertoire of the avant-garde era, however, has vastly changed the aural expectations to include more aggressive sounds through the use of extended techniques. Even though so-called extended techniques are often viewed as a new development, several have been in practice since the fourth and fifth centuries. A historical overview of such techniques demonstrates their significance in contemporary music. More recently, the solo flute repertoire has included interdisciplinary art forms such as theatrical elements, a much newer concept that was integrated during the mid-twentieth century. Though …

Teacher And Administrator Perceptions Of One-To-One Technology Device Implementation, Stewart F. Pratt

Dissertations

The influence of technology on society shows little sign of diminishing (Puybaraud, 2012). Increased capabilities and the affordability of technology devices have brought a resurgence of one-to-one device implementation in schools (Dawson, 2016). This qualitative study was designed to elicit the perceptions of administrators and teachers on one-to-one device implementation. Marc Prensky’s (2001) premise that students are digital natives embedded in media and digital device-rich environments provided the conceptual framework for this study. Furthermore, Prensky (2001) proposed modern students learn, conceptualize, and respond differently than previous generations. The participants in this study represented six southwest Missouri school districts with student …

Going 1:1- Writing Policy To Support The 21st Century Student: A Policy Advocacy Document, Tracey K. Landry

African American Men’S Health: Regulating Race-Related Stress Through Cognitive Flexibility, Brian P. Littleton

Dissertations

African American men have one the highest preventable mortality and morbidity rates in the United States (Rich, 2000; U.S. Department of Health and Human Services, 2015). Moreover, there is substantial health disparity between African American men and White men in the United States (Smedley, Stith, & Nelson, 2003). It has been stated that pervasive racism and discrimination are the most significant contributors for the disparity. Studies have shown race-related stress, which is derived from experiencing racism, discrimination or having internalized feelings as the result of an individual’s racial status, has been associated with blood pressure, emotional distress, and physical health …

Transitioning Children With Autism From One-On-One Discrete-Trial Settings To Special Education Classrooms, Jennifer L. Freeman

Dissertations

The goal of an early intensive behavioral intervention (EIBI) program is to teach each child the skills necessary to make meaningful progress in less-restrictive environments (Fox, Dunlap & Crushing, 2002). However, few studies have detailed the steps necessary for a “successful” transition into these educational settings. We transitioned two children, who received 20 hours a week of one-on-one discrete-trial therapy and attended a half-day special education pre-school classroom, to a full-time educational setting. With the goal of aiding each during his/her transition, this study used the Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP) (Sundberg, 2008), particularly the barriers and …

La Sexualidad Como Vehículo De La Identidad De Género, Sexual Y Nacional En La Novelística Panhispánica Del Siglo Xxi, Leticia Isabel Espinoza

Dissertations

The search for identity in twentieth-century Spanish-language literature has primarily been seen through the rewriting of history to better suit new generations. For instance, One Hundred Years of Solitude, Gabriel García Márquez’s novel about the origins of Colombia and Latin America, fictionalizes historical facts and rewrites history to question the very identity of Latin American countries. However, the search for identity in twenty-first-century Spanish language novels is unique in the sense that it does not look for identity through history, but through sexuality. Due to the lack of research in this area, the purpose of this study is to demonstrate …

Factors Affecting Community Participation In Young Adults With Intellectual And Developmental Disabilities, Molly Bathje

Dissertations

Young adults with intellectual and developmental disabilities (IDD) participate less frequently in communities than other disabled and non-disabled peers (Verdonschot, de Witte, Reichrath, Buntinx, & Curfs, 2009) even though they express a desire to participate (Kampert & Goreczny, 2007) and federal policy mandates community inclusion (Haertl, 2014). Participation in one’s community is linked to health and quality of life (World Health Organization, 2002). The broad goal of this three paper dissertation is to contribute to a deeper understanding of what facilitates and impedes community participation for young adults with IDD by (1) developing a new conceptual model, (2) evaluating a …

Counselor Preparation And Adolescent Youth: A Study Of Clinical Mental Health Counselors, Brian R. Russ

Dissertations

Prevalence data have raised concerns that child and adolescent mental health issues are at an epidemic level. For example, Knopf, Park, and Mulye (2008) suggested that 20-25% of all youth experience symptoms of distress. Researchers have also estimated that one in five adolescents in the United States have a diagnosable mental health disorder, and one in ten with a disorder that would be considered severe (Kessler, Berglund, Demler, et al., 2005; Knopf, Park, & Mulye, 2008). Yet, the training of clinical mental health counselors who work with adolescent populations has received limited attention in the counselor education literature. Although the …

The Case For Cultural Proficiency For Teachers Of Students Of Color Who Live In Poverty: A Policy Advocacy Document, Perry A. Finch

Dissertations

This document explores how expanding educators’ cultural proficiency leads to increased learning opportunities for students of color who live in poverty. Through the development of culturally responsive curriculum and instruction, teachers might increase their abilities to meet the needs of previously disenfranchised students. A connection exists between differentiated instruction and culturally responsive instruction, as both require a heightened understanding of students’ schema, interests, and culture. This policy argues that increasing educators’ cultural proficiency should not be done simply to increase teacher effectiveness with instruction but rather because it is a moral obligation of schools.

School Libraries, Disabilities, And A Phenomenological Progression To Policy Change, Patrice Narret Foerster

Dissertations

Research has shown that school librarians are not well equipped to work with students who have disabilities. Applying a conceptual framework culled from the public policy process literature, this phenomenological study used interviews with Washington, DC, policy workers--some of whom advocate for students with disabilities--to explore the possible connection between library experiences and the placement of libraries within the Elementary and Secondary Education Act (ESEA). The findings indicate that these workers are not framing libraries in the same way that library professionals do and are not viewing school libraries as a direct source of student instruction. This dichotomy suggests that …
