Lysine Specific Demethylase-1 And The Brahma Chromatin Remodeling Complex Regulate Conserved Signaling Pathways During Drosophila Wing Development, Brenda Jean Curtis

Dissertations

The conserved SWI/SNF chromatin remodeling complex uses the energy from ATP hydrolysis to alter local chromatin environments by disrupting DNA-histone contacts. The Drosophila SWI/SNF counterpart, the Brahma complex, has been shown to have an essential role in regulating the proper expression of many developmentally important genes, including those required for eye and wing tissue morphogenesis. A temperature sensitive mutation in one of the core subunits, SNR1 (SNF5/Ini1/SMARC B1), results in reproducible wing patterning phenotypes that can be enhanced and suppressed by extragenic mutations. SNR1 functions as a regulatory subunit to modulate chromatin remodeling activities of the Brahma complex on target …

Quality Of Life And Health Outcomes In Overweight And Non-Overweight Children With Asthma., Amy Becker Manion

Dissertations

Over the last two decades the number of children and adolescents who are overweight has more than doubled. Currently, an estimated 18 percent of children and adolescents ages 6-19 years are overweight. Following this trend in childhood overweight, there has been an alarming increase in the number of children with asthma who are overweight. The increasing trend in both asthma and overweight has led to the suggestion of a causal relationship between the two. Childhood overweight has been found to have a profound negative impact on quality of life (QOL), yet there is a dearth of research regarding the impact …

An Evaluation Of Health Behavior Change During A General Education Health Course, Lynn M. Merklin

Dissertations

Problem. There have been no studies as to the effectiveness of the one-credit general education health course at Andrews University, Fit for Life, in promoting the adoption of healthy lifestyle behaviors. Because behavior change is a process that occurs over time, any measurement of student health behaviors must be sensitive enough to detect the early stages of behavior change as well as the behaviors themselves.

Method. The purpose of this study was to determine the degree to which students enrolled in Fit for Life adopted the health behaviors promoted in the course, evidenced by progress through the stages …

Cosmological Beliefs About Origins Related To Science Achievement Among Junior High-School Students In South Bend, Indiana, J. David Van Dyke

Dissertations

Problem. American high-school students score lower in science achievement tests than their peers in other developed nations. The Organization for Economic Cooperation and Development (OECD) ranked the scientific achievement of American high-school students as ―very low‖ in comparison to high-school students in other industrialized nations—only 29th out of 57 developed countries. Research has indicated that achievement declines as U.S. students progress to higher grades and take on more rigorous science courses. A variety of factors have been documented that may account for U.S. students‘ lower science achievement rankings. These include socioeconomic status, race, and gender. One area only marginally …

Haima In Hebrews, Hermann V. Kuma

Dissertations

Problem. The focus of the dissertation is the significance of the term αἷμα (“blood”) in the Epistle to the Hebrews and how the author of Hebrews uses the term to formulate the argument and message of the Epistle. The dissertation traces the scholarly blood debate involving blood as life or death which began in the last decade of the nineteenth century and eventually fizzled out in the mid-1950s. Recognition of the ambivalence of blood, symbolizing both life and death, is necessary to understand the message of Hebrews.

Method. The dissertation provides a discussion of the concept of blood in the …

The Heterosexual Mother-Lesbian Daughter Relationship: Using Consensual Qualitative Research (Cqr) To Understand Perceptions Among Predominately White, Formally Educated Mothers, Julie Meredith Davis

Dissertations

Little research specifically addresses the heterosexual mother-lesbian daughter relationship. Given this, a core research team of six utilized a Consensual Qualitative Research (CQR) approach to gain insight into two broad ideas. The first broad idea was about how heterosexual mothers perceive that their relationship with their lesbian daughters unfolds after the mothers accepted their daughters' minority sexual orientation. The second broad idea was how changes in the heterosexual mothers' values, beliefs, and attitudes (from the mothers' perspectives) influenced their postacceptance relationship with their daughters. The 10 women who agreed to participate in the study were predominately white, formally well-educated, psychologically …

A Molecular Analysis Of Training Multiple Versus Single Manipulations To Establish A Generalized Manipulative Imitation Repertoire, Breanne K. Hartley

Dissertations

This study evaluates the necessity of training multiple versus single manipulativeimitations per object in order to establish generalized manipulative-imitation. Training took place in Croyden Avenue School's Early Childhood Developmental Delay preschool classroom in Kalamazoo, MI. Two groups of 3 children each were trained to imitate in order to determine the most appropriate number of manipulations required (per object) to establish a generalized manipulative-imitation repertoire. Three children received single-manipulations training, and 3 children received multiple-manipulations training. It was anticipated that the multiple-manipulations training group would acquire a greater amount of generalized manipulative-imitation because the training required that the children discriminate between …

Neon Allegiance, Jason Paul Olsen

Dissertations

This collection of thirty-one poems is built around my personal search for place, the idea of "home," and how it is relationship more than mere geography that defines the places one encounters in a life. In these poems, that idea of "home" ties back to intimate relationships with family and friends, but also with relationships involving culture—both historical and popular—as a whole.

The collection itself is a pastiche of strategies and stylizations, united by a defined and consistent voice. The geographic locations vary—from Las Vegas (where the largest number of poems and energy are focused) to stops in points across …

Conservation Genetics And Systematics Of Several Turtles Species In The Southeastern United States, Joshua Robert Ennen

Dissertations

Chelonians (i.e., turtles) are an imperiled group of reptiles with about 66% of the recognized species listed as threatened by the IUCN. Most chelonian species have a unique set of life history traits (i.e., longevity, delayed sexual maturity, and low juvenile survivorship), which makes their populations exceedingly sensitive to increases in adult and juvenile moralities. With numerous anthropogenic effects (e.g., habitat alteration, exploitation, and over harvesting) negatively influencing mortality rates, chelonians have experienced global precipitous declines and extinctions.

This dissertation focuses on species within two chelonian genera, Gopherus and Graptemys. Although these two genera are vastly different ecologically, they are …

Teaching Science In Light Of World View: The Effect Of Contextualized Instruction On The Scientific Compatibility Of Religious College Students' World Views, Paula Rae Gossard

Dissertations

Authors of recent science reform documents promote the goal of scientific literacy for all Americans (American Association for the Advancement of Science, 1989, 1993). Some students, however, feel apprehensive about learning science due to perceptions that science is antagonistic to their world views (Alters, 2005; Esbenshade, 1993). This study investigated the effect of an introductory science course taught in the context of a Christian, theistic world view on the scientific compatibility of religious college students' world views. For the purposes of this study, students' understanding of the nature of science, affective attitudes toward science, and beliefs regarding creation were used …

A Conceptual Integration Analysis Of Multiple Instructional Metaphors, Robert Johnson

Dissertations

The present study was conducted to investigate some of the practical implications of conceptual integration theory for educators. This research was a mixed-methods study exploring how improvements in understanding—learning—(as measured by a selectedresponse assessment) are reflected in changes in learner language (described in terms of conceptual integration patterns). After a pretest with open-response and selected-response prompts, two groups of young adult participants viewed different videos of a slightly different review lesson in genes, genetics, and heredity, the difference lying in two different metaphor conditions: the experimental group was shown a more “metaphorrich” version of the lesson using two classic metaphors …

Mapping The Global Landscape In Women's Diasporic Writing, Martha Addante

Dissertations

As a contribution to the theory of cognitive mapping, the dissertation examines the ways in which contemporary novels by women writers of diasporic literature offer new conceptual maps of the present global space. This study argues there is a need for alternative mapping strategies that locate the female diasporic subject within the new global political economy. Fredric Jameson's theory of cognitive mapping and Arjun Appadurai's model of global flows provide a useful framework for mapping global space, yet each must be filtered through a feminist critique and modified by a feminist politics. Ultimately, the dissertation argues for a feminist theory …

From Picture To Word To The World: A Multimodal, Cultural Studies Approach To Teaching Graphic Novels In The English Classroom, Shannon Renee Mortimore

Dissertations

Sequential narratives such as comics, graphic novels and Manga (Japanese-style comics) have long been popular in youth culture. Recent attention has shifted to the potential of utilizing these alternative texts in the secondary classroom, yet very little information for English teachers exists regarding how to engage students in close, careful, and culturally informed analysis of these works. While there is a long tradition of thoughtful analytical teaching about literary texts, when it comes to the study of various media with strong image content, language arts teachers often may not know how to proceed. Indeed, preconceptions about the legitimacy of comics …
