Stabel Isotope Turnover Rates And Diet-Tissue Discrimination In The Skin Of West Indian Manatees: Implcations For Evaluating Their Feeding Ecology And Habitat Use, Christy Alves
Electronic Theses and Dissertations
The West Indian manatee (Trichechus manatus) is an herbivorous marine mammal that occupies freshwater, estuarine, and marine habitats. Despite being considered endangered, relatively little is known about the feeding ecology of either of the two recognized subspecies, the Florida manatee (T.m. latirostris) and Caribbean or Antillean manatee (T.m. manatus). A better understanding of their respective feeding preferences and habitat use is essential to establish criteria on which conservation plans can be based. The present study expands on previous work on manatee feeding ecology by both assessing the application of stable isotope analysis to manatee tissue and providing critical baseline parameters …
Restoration Of Intertidal Oyster Reefs Affected By Intense Recreational Boating Activity In Mosquito Lagoon, Florida, Andrea Barber
Restoration Of Intertidal Oyster Reefs Affected By Intense Recreational Boating Activity In Mosquito Lagoon, Florida, Andrea Barber
Electronic Theses and Dissertations
In recent years, intertidal reefs of Crassostrea virginica (eastern oyster) along central Florida's east coast have suffered extensive losses due to wakes from recreational boats. These wakes have caused extensive shell movement and sediment resuspension which results in large piles of disarticulated shells along the seaward edges of reefs. Dead margins extend up to one meter above mean high water. The creation and enforcement of "no wake" zones in the area are unlikely. Thus, there is an urgent need for an alternative restoration strategy before these oyster reefs decline any further. The goal of this project was to develop a …
African Religious Integration In Florida During The First Spanish Period, Christopher Beats
African Religious Integration In Florida During The First Spanish Period, Christopher Beats
Electronic Theses and Dissertations
This thesis is an examination of the unique conditions for African-descended slaves in St. Augustine, Florida, during the First Spanish Period. St. Augustine was an important garrison at a remote point in the Spanish Empire at the edge of a hostile frontier. As such, economics were less a priority than defense. Slaves, therefore, received different treatment here than in English colonies or even other Spanish colonies. Due to the threat of Protestantism, religious adherence was more important as a test of loyalty than ethnicity and slaves and freed-people were able to integrate better than in other Spanish holdings. In order …

Genetic And Phenotypic Evolution In The Ornate Chorus Frog (Pseudacris Ornata): Testing The Relative Roles Of Natural Selection,, Jacob Degner
Electronic Theses and Dissertations
Understanding how migration, genetic drift, and natural selection interact to maintain the genetic and phenotypic variation we observe in natural populations is a central goal of population genetics. Amphibians provide excellent model organisms for investigating the interplay between these evolutionary forces because amphibians are generally characterized by limited dispersal abilities, high philopatry, and are obligately associated with the areas around suitable habitats (e.g. breeding ponds). Thus, on relatively small geographic scales, the relative effects of all of these evolutionary forces can be studied together. Here, we study the interaction of migration, genetic drift, natural selection, and historical process in the …
The Emergence Of The Maya Tlaloc: A Late Classic Religious Icon, Amanda Toyie Groff
The Emergence Of The Maya Tlaloc: A Late Classic Religious Icon, Amanda Toyie Groff
Electronic Theses and Dissertations
Iconography has the capability to memorialize and guarantee one's place in history; iconography can also provide powerful insight into human culture, and explore social and cultural values in a visual manner. Iconography can incorporate information about group identities, allegiances, religious affiliations, propaganda, and acceptance within both modern and ancient societies. By studying a specific iconographic figure, the Central Mexican god Tlaloc, as a visual representation of a belief or identity, we can glean a greater understanding of the cultural transmission of iconographic symbols. The substantial use of this icon, in both Central Mexico and the Maya region, reveals iconography as …

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 …

The new model provided the critical relationship between the senior health information system and other technology acceptance components. Computer self-efficacy was added to the hypothetical model to better explain the seniors' technology usage and performance. The hypotheses and the research …
Real-Time Tree Simulation Using Verlet Integration, Bobak Manavi
Real-Time Tree Simulation Using Verlet Integration, Bobak Manavi
Electronic Theses and Dissertations
One of the most important challenges in real-time simulation of large trees and vegetation is the vast number of calculations required to simulate the interactions between all the branches in the tree when external forces are applied to it. This paper will propose the use of algorithms employed by applications like cloth and soft body simulations, where objects can be represented by a finite system of particles connected via spring-like constraints, for the structural representation and manipulation of trees in real-time. We will then derive and show the use of Verlet integration and the constraint configuration used for simulating trees …

Applying The Appraisal Theory Of Emotionto Human-Agent Interaction, Aaron Pepe
Electronic Theses and Dissertations
Autonomous robots are increasingly being used in everyday life; cleaning our floors, entertaining us and supplementing soldiers in the battlefield. As emotion is a key ingredient in how we interact with others, it is important that our emotional interaction with these new entities be understood. This dissertation proposes using the appraisal theory of emotion (Roseman, Scherer, Schorr, & Johnstone, 2001) to investigate how we understand and evaluate situations involving this new breed of robot. This research involves two studies; in the first study an experimental method was used in which participants interacted with a live dog, a robotic dog or …
An Investigation Of The Relationship Between Graduate Counseling Students' Perceptions Of Spirituality And Counselor Self-Ef, Sandra Pollock
An Investigation Of The Relationship Between Graduate Counseling Students' Perceptions Of Spirituality And Counselor Self-Ef, Sandra Pollock
Electronic Theses and Dissertations
Counseling and psychology have experienced a conflicted relationship with the issue of spirituality over the last century. Spirituality is a construct that has been receiving more attention in counseling over the last fifteen to twenty years. More counselors and educators are affirming its place and value in the counseling relationship. Yet, there is a disparity between this and what counselors-in-training are being taught regarding spirituality, its value to clients and counselors, and its role in the counseling relationship. Very little research has been done examining spirituality and its relationship to counseling students level of confidence and competence in their work--their …
Characterization Of Pigment Cell Specific Genes In The Sea Urchin Embryo (Strongylocentrotus Purpuratus), Tricia Stephens
Characterization Of Pigment Cell Specific Genes In The Sea Urchin Embryo (Strongylocentrotus Purpuratus), Tricia Stephens
Electronic Theses and Dissertations
In sea urchin development, cell fate specification appears by the 60-cell stage embryo when several embryonic territories are recognized: the small micromeres, the large micromeres which will generate primary mesenchyme cells, the vegetal2 layer that will give rise to pigment cells, immunocytes, and muscle cells, the vegetal1 layer, as well as the oral and aboral ectoderm. A Delta-Notch signaling event is required for the differential specification of mesodermal cells that will give rise to secondary mesenchyme cells (SMCs). SMCs produce four cell types: pigment cells, blastocoelar cells, circumesophageal muscle cells, and coelomic pouch cells. Pigment cells are the first to …
Responses Of Small Rodents To Restoration And Management Techniques Of Florida Scrub At Cape Canaveral Air Force Station, Florid, Alexis Suazo
Electronic Theses and Dissertations
Proper habitat management is essential for the survival and reproduction of species, especially those listed under state or federal laws as endangered, threatened or of special concern, and those with small local populations. Land managers use a combination of mechanical cutting and prescribed burning to manage and restore degraded scrub habitat in east central Florida. This approach improves habitat for the endangered Florida scrub-jay (Aphelocoma coerulescens), but little is known about its effects on other taxa, especially the threatened southeastern beach mouse (Peromyscus polionotus niveiventris). This single species approach may not be beneficial to other taxa, and mechanical cutting and …
The Effect Of In-Vehicle Warning Systems On Driverresponse In Work Zones, James James Whitmire Ii
The Effect Of In-Vehicle Warning Systems On Driverresponse In Work Zones, James James Whitmire Ii
Electronic Theses and Dissertations
This research investigated the effectiveness of in-vehicle information technologies on driver behavior in work zones. In-vehicle information devices can increase driver awareness to an oncoming change in traffic flow and provide specific guidelines for driving speed requirements, lane merging strategies, or unexpected changes in the roadway (e.g., detours and lane shifts). The overall conditional effects for vehicle speed are significant; that is, both the audio and visual groups out performed the control group within the simulated work zone. Participants in audio group did outperform the visual group, not significantly though. The overall conditional effects for total time in violation are …

Redefining Choreography For The "The Rocky Horror Show" For A New Generation Of Actors, Timothy Ellis
Redefining Choreography For The "The Rocky Horror Show" For A New Generation Of Actors, Timothy Ellis
Electronic Theses and Dissertations
As many veterans of musical theatre strive to keep a stronghold on the traditional form of the art with shows like "Oklahoma," "Show Boat" and "Carousel," we must recognize the life of said art form must also appeal to the mindset of new generations. In 1973, a rock musical began making waves in London's theatrical community. "The Rocky Horror Show" was like nothing anyone had seen before. The show had a plot but was presented like a rock show. The characters paid homage to a youthful faction of society wanting to express its individualism. Musicals continue to explore new avenues …

In this study, I worked with an ensemble of teenagers from Ayts Chayim Messianic Synagogue in Boca Raton, Florida to develop an original Purim play to be presented for the congregation and the public. I specifically explored "What is theatre's role as a worship tool in a Messianic Jewish Synagogue?" My ultimate goal in this process was to honor God through the creative arts, and I used the process of creating the play to discover the specific ways that theatre can be used as a worship tool, from script development to theatrical presentation. I hypothesized that theatre could be used …
Food For Joyous Laughter: Contemporary Productions Of Gilbert & Sullivan's The Pirates Of Penzance, Julia Winstead
Food For Joyous Laughter: Contemporary Productions Of Gilbert & Sullivan's The Pirates Of Penzance, Julia Winstead
Electronic Theses and Dissertations
The operetta, The Pirates of Penzance, is a classic work by Gilbert and Sullivan, a work that continues to be produced frequently despite its Victorian setting and operatic style. For many years the standard performance style of all the operettas by Gilbert and Sullivan was upheld by the D'Oyly Carte Opera Company, who attempted to perform the operettas as they had originally been done. Though the D'Oyly Carte Opera Company helped stimulate interest in the works of Gilbert and Sullivan, nontraditional productions of G & S operettas produced outside of the company were able to reach larger audiences. When The …
Let The Children Come To Me, Andrea Ramirez
Let The Children Come To Me, Andrea Ramirez
Electronic Theses and Dissertations
My thesis, a collection of personal essays, explores my parents' affinity towards their native Colombia and how this connection to their homeland, through their faith and their customs, affected my definition of self. When I think about my parents' emigration from Colombia to the States, I picture the illustrations in the Bible I had as a child: the couple running from Sodom and Gomorra, running away from the place they had always known and holding on to each other. My parents, like the couple in the Bible, were in the middle of nowhere when they first set foot on the …

This inquiry is designed to explore first-year composition students' advances in technological literacy, specifically hypertext reading and research strategies. To accomplish this, a hypertext-reading project was designed to investigate the ways in which first-year composition students assimilate and employ hypertext information as a source from which they must extract information to use in the development of an argument. A program, designed and written specifically for this project, presented research participants, 76 …
Tree Calls Of Three Treefrogs (Hyla Femoralis, H. Gratiosa, And H. Squirella): Analysis Of Environmental, Behavioral, And Acoustic Characteristics, Kristine Schad
Electronic Theses and Dissertations
Male frogs typically call near water at dusk to attract females for breeding. During the breeding season, male treefrogs also emit diurnal "tree calls" or "rain calls" from the tops of trees. Very little is known about tree calls, although many treefrogs use them. Tree calls may be used to attract females, deter males or be triggered by weather conditions favorable for breeding: high temperature and relative humidity, and a drop in barometric pressure. As dusk approaches, male treefrogs continue tree calls from lower in the trees, and if conditions are favorable, jump to the ground and travel to a …
Smoke And Mirrors: A Cultural-Psychological Analysis Of Tobacco Use, Michael Melczak
Smoke And Mirrors: A Cultural-Psychological Analysis Of Tobacco Use, Michael Melczak
Electronic Theses and Dissertations
This theoretical dissertation explores tobacco use from the perspectives of social constructivism and phenomenological depth psychology. In Part I, tobacco use is described as a cultural artifact, and transformations in tobacco use are traced through three different cultural contexts or "worlds": the indigenous or aboriginal worldview, the European and American worldview of the 17th through mid-19th centuries, and the modern American worldview (or "modernity"). In each of these worldviews, the cultural context informed and influenced (or reflected and reproduced) understandings of tobacco use. One notices the transformation of tobacco use, for example, from a god to a commodity and from …

Amphibian Colonization Of New Habitat : "If You Build It, They Will Come"., Piper Lee Roby-Thomas 1977-
Electronic Theses and Dissertations
In 2003, Wilson Creek running through Bernheim Arboretum and Research Forest in central Kentucky was restored to its original winding path through a valley field. Early 20th century settlers had previously redirected this creek to run a straight path along the eastern hillside in order to maximize the valley for farming. As part of the restoration to its pre-settler path, seven ponds were created in the corridor of the old streambed, which created habitat for pond-breeding amphibians. Sampling began one year after construction was complete, and over two years the amphibian assemblages of these ponds were compared to those of …
Gary Snyder's Idiosyncratic Buddhist Poetics And The "Razoredge"., David Gerhardt Thimme 1970-
Gary Snyder's Idiosyncratic Buddhist Poetics And The "Razoredge"., David Gerhardt Thimme 1970-
Electronic Theses and Dissertations
Gary Snyder's poetry conveys Zen states of consciousness through unconventional grammar and syntax. From his first book Riprap in 1959 to his last collection of poems, Mountains and Rivers Without End in 1996, he has confronted the challenge of transforming Buddhist philosophy and discourse into Western poetics. Snyder's syncretism pertaining to Buddhist and Native American beliefs form a unique view of Zen that suggests his precise involvement with the meditative self-discipline may be unstable and elusive. A close reading of Snyder's idiosyncratic Buddhist poetics reveals an impasse between a "non-verbal" realm, where the Cartesian duality of subject and object dissolves, …
