Juvenile Ornamentation: Its Evolution, Genetic Basis, And Variation Across Habitats, Angela Tringali

Electronic Theses and Dissertations

Ornamental traits are considered honest advertisements of fitness, and their evolution is usually explained in terms of sexual selection. This explanation remains unsatisfactory in some instances, for example, juvenile birds whose plumage is molted prior to adulthood and breeding. I first evaluate whether juvenile plumage reflectance signals dominance status in the Federally Threatened Florida scrub-jay (Aphelocoma coerulescens) using a combination of observational and experimental methods. Then I estimate the heritability, non-genetic maternal and environmental effects, and strength of selection on juvenile plumage reflectance using archived feather samples and a pedigree constructed from historical nest records. Finally, I compare plumage reflectance …

Leading Schools Through A Generational Lens: Perceptions Of Principals' Change Leadership Disaggregated By Principal Generation, Matthew Scott Kuhn

Electronic Theses and Dissertations

The purpose of this descriptive quantitative study was to investigate possible differences in school leadership within a change process, as perceived by teachers. Grouped by generation, this study investigated principals’ perceptions of change order and that of their teachers, as well as how their teachers perceived their principal’s leadership capacity when leading 1^st and 2^nd order change. This was done by analyzing data from Mid-continent for Education and Learning’s Balanced Leadership Profile®. McREL surveyed principals about the order of school change initiatives and their capacity to lead change. McREL also surveyed teachers about the 1_^st and 2 …

"What Do You Mean I'M A Slut?!?!" : Deconstructing The Definitions Of Promiscuity Of The Collective Conscience Using Concepts From Labeling Theory And Biopower., Joshua O. Corum

Electronic Theses and Dissertations

The term "promiscuity" is often used in academic literature and pejoratively proliferated among society at large. The definition of promiscuity has not been clearly and consistently defined within research and varies significantly from person to person. However, both research and society continue to utilize this term with the assumption of a universal meaning. This study investigated how individuals construct their personal definition of promiscuity and how the subsequent label is applied to others. This thesis also examined how the definition of promiscuity is constructed within the collective conscience and how social institutions influence that definition. The relationship between the collective …

Black Men's Responsible Fatherhood Narratives: Fatherhood, Responsibility, Race, And Gender, Shane Chaplin

Electronic Theses and Dissertations

Over the last few decades increasing rates of single mother households in the United States have triggered a national alarm over the effects of father absence on society. Father absence has been linked specifically to many of the problems plaguing black communities in the United States (e.g. poverty, low educational attainment, etc.) and as a result community and political leaders alike have consistently promoted responsible fatherhood practices as a way to address them. Although responsible fatherhood has received, in this context, a considerable amount of social attention, this attention has come intertwined with considerable political and moral rhetoric at all …

Free Clinics And The Uninsured: The Need For Remote Area Medical In Central Appalachia After Health Reform., James W. Watson

Electronic Theses and Dissertations

In 2008, the election of President Barack Obama brought health care to the forefront of national discussions and led to the passage of the Patient Protection and Affordable Care Act (ACA). The legislation changed the rules of health care delivery in the United States, but the ACA did not do one fundamental thing: It did not end the need for many of the nation's most needy patients to seek free medical care from groups such as Remote Area Medical (RAM).

A mobile clinic, RAM brings together volunteer dentists, physicians, nurses, and other professionals as well as support staff for multi-day …

Minorities In Israel: Mizrahi And Israeli-Arab Identity And The Potential For Political Collaboration, Kristin L. Hissong

Electronic Theses and Dissertations

The purpose of this thesis is to analyze the minority status of Mizrahim and Israeli-Arabs and their political narrative, identity, and action, including their divergent and collaborative views of the Israeli-Palestinian Peace Process. I examined the possibility that minority groups, once established as viable separate collectives with some leverage and political narrative, have just cause for combining their political action in order to influence governing elites. In order to explore this question, I investigated whether the factor of shared grievances in social identity formation provides a basis for multi-group political narrative and subsequent collaborative action in confronting dominant political forces, …

The Millennial Rumor: Understanding Millennial College Students' Characteristics, Digital Media Technology Usage, And Assumptions At The University Of Denver, Christina M. Murray

Electronic Theses and Dissertations

This quantitative study investigated student and faculty attitudes toward use of Digital Media Technology (DMT) at the University of Denver. The purpose was to understand how and why students and faculty used DMT on campus. Uses and gratifications theory (Katz, Blumler, & Gurevitch, 1974) was used as the theoretical model to interpret and understand Millennial college students' DMT use, Langer and Knefelcamp's (2008) College student technology arc was used as a conceptual model. Two survey instruments were designed: one for faculty and one for students to collect data on DMT use and attitudes toward use, satisfaction, skill, and learning at …

The Effects Of Urbanization On Cypress (Taxodium Distichum) In Central Florida, Lisa A. Mccauley

Electronic Theses and Dissertations

Urbanization is accelerating in the United States and is contributing to fragmentation of natural habitats, causing changes in species composition and declines in native species. Human population growth in Orlando is typical of growth in the southeastern United States and throughout the range of cypress (Taxodium distichum). Orlando has numerous isolated cypress wetlands, called cypress domes, and many remain among the current urbanized area. This makes Orlando ideal to study the effects of urbanization on cypress domes. Specifically, I tested how urbanization and its effects on fragmentation, hydrology, and fire regime) affected (a) the numbers and spatial pattern of cypress …

Inhibition Of Escherichia Coli Atp Synthase By Polyphenols And Their Derivatives., Prasanna Keerthi Dadi

Electronic Theses and Dissertations

We have studied the inhibitory effect of natural and structurally modified polyphenols on Escherichia coli ATP synthase to test (I) if the beneficial dietary effects of polyphenols are related to their inhibitory actions on ATP synthase, (II) if inhibitory effects of polyphenolic compound could be augmented through structural modifications, and (III) if they can act as antimicrobial agent through their actions on ATP synthesis. X-ray crystal structures of polyphenol binding sites suggested that polyphenols bind at a distinct polyphenol binding pocket, at the interface of α,β,γ-subunits. We found that both natural and modified polyphenols inhibit E. coli ATP synthase to …

Disclosure, Social Reactions To Disclosure, And Mental Health Outcomes Among Adult Child Sexual Abuse Victims., Holly E. Hopson

Electronic Theses and Dissertations

Child sexual abuse (CSA) is a frequent problem in American society associated with a wide range of negative mental health outcomes. Some evidence suggests that disclosure may moderate the relationship between CSA and mental health. However, the specific reactions a victim receives following disclosure may directly affect the impact that disclosure has on mental health. The current study directly and simultaneously evaluated the roles of disclosure and social reactions in relation to mental health outcomes. The sample consisted of 652 undergraduate students at East Tennessee State University who completed an on-line, self-administered questionnaire. Forty-four (6.75%) of the participants reported experiencing …

Treefrog (Hyla Squirella) Responses To Rangeland And Management In Semi-Tropical Florida, Usa, Kathryn Windes

Electronic Theses and Dissertations

As urban areas expand, agricultural lands become increasingly important habitat for many species. Compared to some types of agricultural land-use, ranchlands provide vast expanses of minimally modified habitat that support many threatened and endangered species. Conservation biologists can promote ecologically sound management approaches by quantifying the effects of agricultural practices on resident species. I examined the effects of pasture management, cattle grazing, and landscape characteristics on both adult and larval treefrogs in a ranchland in south-central Florida. I experimentally determined optimal deployment of artificial treefrog shelters constructed of polyvinylchloride (PVC) pipe to efficiently sample adult treefrogs (Chapter 1). Seventy-two shelters …

Students' Perceptions Of Collaboration Tools In A Higher Education Online Collaborative Learning Environment, Kirk Henry

Electronic Theses and Dissertations

Higher education funding and student behavior has been changing rapidly (Dervarics,2008). Because of this, there has been an increased focus on the use of alternative tools for course delivery. One of the emerging areas of focus has been an increased interest in the use of communication and information technologies (Curtis & Lawson, 2001). Currently, there are a wide variety of flexible delivery methods that have been used as well as their associated tools. Naturally, questions have been raised about the efficacy of these tools on the quality of student-student, student-teacher, and student-content interaction (Curtis & Lawson, 2001). Interaction and Collaboration …

A Model Of Flow And Play In Game-Based Learning The Impact Of Game Characteristics, Player Traits, And Player States, Davin Pavlas

Electronic Theses and Dissertations

In this dissertation, the relationship between flow state, serious games, and learning was examined. Serious games, which are games that convey something other than enjoyment (e.g., learning), are increasingly popular platforms for research, training, and advertisement. The elements that make serious games useful to researchers, trainers, and practitioners are closely linked to those that make up the positive psychology construct of flow state. Flow state describes an optimum experience that is encountered when a variety of factors are met, and is characterized by high focus, engagement, motivation, and immersion. While flow state is often discussed in the serious games literature, …

Using The Activity Vector Analysis To Determine Teacher Dispositions For Charter School Teachers In Urban High Schools, Linda M. Clautti

Electronic Theses and Dissertations

This study examined responses to the Activity Vector Analysis by both teachers and students in two urban charter high schools. The premise of this research was that the five dispositions of assertiveness, sociability, calmness, conformity, and conscious restraint were needed to be successful particularly in teaching urban students in charter high schools. Dispositions are "The values, commitments, and professional ethics that influence behaviors toward students, families, colleagues, and communities and affect student learning, motivation and development as well as the educator's own professional growth" (National Council for Accreditation of Teacher Education [NCATE], 2000).

The researcher wanted, first, to see what …

Landcover Change And Population Dynamics Of Florida Scrub-Jays And Florida Grasshopper Sparrows, David Breininger

Electronic Theses and Dissertations

I confronted empirical habitat data (1994-2004) and population data (1988-2005) with ecological theory on habitat dynamics, recruitment, survival, and dispersal to develop predictive relationships between landcover variation and population dynamics. I focus on Florida Scrub-Jays, although one chapter presents a model for the potential influence of habitat restoration on viability of the Florida Grasshopper Sparrow. Both species are unique to Florida landscapes that are dominated by shrubs and grasses and maintained by frequent fires. Both species are declining, even in protected areas, despite their protected status. I mapped habitat for both species using grid polygon cells to quantify population potential …

Women, Art, And Community: A Proposal For A Non-Profit Pottery Program In Appalachia., Lahla K. Deakins

Electronic Theses and Dissertations

Many Appalachian women are creative individuals who enjoy making and sharing quilts, songs, paintings, poetry, and other art. However, many women in rural areas of Central Appalachia lack access to basic resources because of poverty.

While many agencies help poor women find shelter, clothing, and food, there are few that help them find their creative voices. I assert that women who are given the tools to practice creative expression can overcome the mental oppression of poverty to become self-assured individuals who benefit their communities.

This thesis examines the socioeconomic condition of women in Central Appalachia and the positive impacts of …

Art Therapy Treatment With Incarcerated Women, Bonnie Erickson

Electronic Theses and Dissertations

This study examined the effectiveness of art therapy in decreasing symptoms of trauma and psychological distress in women who were incarcerated in county jails in the Southeastern United States. In order to protect the integrity of the study, control subjects were in different dormitories from the treatment subjects. While the dormitories were randomly assigned to treatment or control, the subjects were not. The dependent measures were paper and pencil tests, the Outcome Questionnaire (OQ-45.2) and the Trauma Symptom Inventory (TSI) given at pretest and posttest. A demographic questionnaire was completed in the first session to better characterize the participants. In …

Does Habitat Affect Clonal Demography? An Experiment With Polygonella Myriophylla In Roadside And Florida Scrub, Kristina Dianne Horn

Electronic Theses and Dissertations

Polygonella myriophylla (Polygonaceae) is a clonal shrub listed as endangered and narrowly endemic to pyrogenic scrub ecosystems in central Florida. It is almost restricted to gaps within the matrix of shrubs in the scrub but also occurs along adjacent road-side habitats. I hypothesize that persistent disturbed microhabitats and more dynamic sand accretion in roadsides will increase rooting probabilities compared to more stable scrub habitats, affecting survival, growth and reproduction. In April 2004- March 2006, I compared plant (genet) and basal branch (ramet) performance between experimentally manipulated plants in native scrub and roadside habitats at two locations within the Lake Wales …

Demographic Consequences Of Managing For Florida Scrub-Jays (Aphelocoma Coerulescens) On An Isolated Preserve., Casey Lyon

Electronic Theses and Dissertations

Many species naturally occupy discrete habitat patches within a mosaic of habitats that vary in quality. The Florida scrub-jay (Aphelocoma coerulescens) is endemic to Florida scrub, a habitat that is naturally patchy and greatly reduced in area over recent decades owing to development and urbanization. Because of this habitat loss, future management of Florida scrub-jays will focus on smaller, fragmented tracts of land. My study examines such a tract, Lyonia Preserve, southwest Volusia County, FL. This preserve was unoccupied by scrub-jays prior to habitat restoration. The preserve is now frequently managed exclusively for scrub-jays as a habitat island surrounded by …

"Don't Believe The Hype": The Construction And Export Of African American Images In Hip-Hop Culture., John Ike Sewell Jr.

Electronic Theses and Dissertations

This study examines recurring motifs and personas in hip-hop.

Interviews with influential hip-hop scholars, writers and music industry personnel were conducted and analyzed using qualitative methods. Interview subjects were selected based on their insider knowledge as music critics, hip-hop scholars, ethnomusicologists, publicists, and music industry positions.

The vast majority of constructed imagery in hip-hop is based on a single persona, the gangsta. This qualitative analysis reveals why gangsta personas and motifs have become the de facto imagery of hip-hop. Gangsta imagery is repeatedly presented because it sells, it is the most readily-available role, and because of music industry pressures.

This …

The Meaning Of Health Among Midlife Russian-Speaking Women In The United States, Lenore Resick

Electronic Theses and Dissertations

The purpose of this study was to discover factors which influence a mentor's decision to engage in a mentoring relationship within campus recreation administration. The present study investigated four areas of inquiry within campus recreation: (a)what are the individual reasons for mentoring women? (b)what organizational factors inhibit or facilitate mentoring women? ©what protégé characteristics attracted mentors? And (d)what outcomes are associated with mentoring women? A qualitative research design from a phenomenological genre was chosen to examine the mentoring relationship from the perspective of the mentor. A group of campus recreation professionals from the Midwest were contacted for the study (N …

Parental Involvement Typologies As Related To Student Achievement., Stacia Maria Derrick-Lewis

Electronic Theses and Dissertations

The purpose of this study was to examine specific parenting practices in four East Tennessee counties to determine their relationships, if any, to student achievement among various demographic groups. The investigation included status variables, such as parents' educational level, annual income level, and family structure. Students' Normal Curve Equivalent scores on the Terra Nova Standardized Test were used to measure student achievement. The Epstein (1987) typologies were used to classify parent involvement modalities.

The analysis consisted of four research questions and were tested at the .05 level of significance. Pearson's product-moment, Spearman's rho, and Kendall's Tau B correlation coefficients were …

The Formulation, Implementation, And Evaluation Of Educational Planning In Public School Districts Of Tennessee, Daniel R. Fielden

Electronic Theses and Dissertations

The legislature of the State of Tennessee enacted The Public Education Governance Reform Act of 1984 as the first step in a restructuring and reform program for Tennessee education. One of the major elements of this piece of legislation was that the state board of education would "... develop and maintain current a master plan for the development of public education, grades kindergarten (K) through twelve (12)." A regulation was passed by the Tennessee State Board of Education mandating that each local board of education in the state should develop and implement a five-year educational plan to include a mission …
