The Cypress Dome 2009 Issue 20, 20th Anniversary Edition, Chris Wiewiora, Editor In Chief

The Cypress Dome

Our magazine takes its name from a natural phenomenon unique to the state of Florida. Cypress Domes form in depressions where the water table is exposed. These formations of pond cypress and black gum trees usually take the shape of near-perfect circles, which are referred co as cypress domes because the trees tend to grow taller in the center. Its nutrient-rich environment is home to tree frogs, great-crested flycatchers, common and oak toads, and numerous other animals.

A Biocultural Analysis Of Nubian Fetal Pot Burials From Askut, Sudan, Lauren Britton

Electronic Theses and Dissertations

The skeletal remains in this study were excavated from the Nubian archaeological island fortress site of Askut (ca. 1850 BC - 1070 BC, New Kingdom/Third Intermediate period), located at the 2nd Cataract of the Nile river in Sudan. These remains were recovered as part of an archaeological expedition from 1962-1964, which was an effort to learn as much as possible about this site before the building of the High Dam in Aswan. Seven fetal skeletons (dated ca. 1260-770 BC) were examined for their biocultural significance. Biological analysis of these individuals indicates a range in developmental age from 36 to 40 …

Habitat Use By The Southeastern Beach Mouse (Peromyscus Polionotus Niveiventris) At Cape Canaveral Air Force Station, Florida, Kathryn Simmons

Electronic Theses and Dissertations

Successful recovery of the federally threatened southeastern beach mouse (Peromyscus polionotus niveiventris) depends in part on an understanding of their habitat requirements. I studied habitat use by beach mice at Cape Canaveral Air Force Station, Florida from March 2005 until March 2006. I livetrapped six grids, three on coastal dunes and three within scrub located inland from the coast. On each grid and trap station, I quantified the extent of bare ground, woody vegetation, non-woody vegetation, height of vegetation, and percentage of coarse sand in the surface soil. I assessed trap success relative to these habitat variables using linear and …

Application Of Alkylsilane Self-Assembled Monolayers For Cell Patterning And Development Of Biolocial Microelectromechanical Systems, Kerry Wilson

Electronic Theses and Dissertations

Advances in microfabrication and surface chemistry techniques have provided a new paradigm for the creation of in vitro systems for studying problems in biology and medicine in ways that were previously not practical. The ability to create devices with micro- to nano-scale dimensions provides the opportunity to non-invasively interrogate and monitor biological cells and tissue in large arrays and in a high-throughput manner. These systems hold the potential to, in time, revolutionize the way problems in biology and medicine are studied in the form of point-of-care devices, lab-on-chip devices, and biological microelectromechanical systems (BioMEMS). With new in vitro models, it …

Vectorpad: A Tool For Visualizing Vector Operations, Jared Bott

Electronic Theses and Dissertations

Visualization of three-dimensional vector operations can be very helpful in understanding vector mathematics. However, creating these visualizations using traditional WIMP interfaces can be a troublesome exercise. In this thesis, we present VectorPad, a pen-based application for three-dimensional vector mathematics visualization. VectorPad allows users to define vectors and perform mathematical operations upon them through the recognition of handwritten mathematics. The VectorPad user interface consists of a sketching area, where the user can write vector definitions and other mathematics, and a 3D graph for visualization. After recognition, vectors are visualized dynamically on the graph, which can be manipulated by the user. A …

Market-Based Asset Management And Shareholder Value: Investigating The Roles Of Human Capital And Factor Markets In Maximizing Returns On Customer Relationships, Chad Milewicz

Electronic Theses and Dissertations

The accountability of marketing investments continues to be a key area of concern for researchers and practitioners (MSI Research Priorities, 2008). In particular, market-based assets, specifically customer relationships, and their potential impact on firm performance are a significant source of interest. Though research in this area continues to grow, little is understood about how investments in human capital and the acquisition of alliance partners through factor markets relate to customer relationship management and the impact of customer relationships on performance. This dissertation presents two studies which, together, investigate how investments in market-based assets influence on abnormal stock returns. In the …

Carbon And Nitrogen Stable Isotope Turnover Rates And Diet-Tissue Discrimination In Florida Manatees (Trichechus Manatus Latirostris), Christy D. Alves-Stanley, Graham A. J. Worthy

Faculty Bibliography 2000s

The Florida manatee (Trichechus manatus latirostris) is a herbivorous marine mammal that occupies freshwater, estuarine and marine habitats. Despite being considered endangered, relatively little is known about its feeding ecology. The present study expands on previous work on manatee feeding ecology by providing critical baseline parameters for accurate isotopic data interpretation. Stable carbon and nitrogen isotope ratios were examined over a period of more than 1 year in the epidermis of rescued Florida manatees that were transitioning from a diet of aquatic forage to terrestrial forage (lettuce). The mean half-life for (13)C turnover was 53 and 59 days for skin …

Thermo-Mechanical Characterization Of High-Temperature Shape Memory Ni-Ti-Pd Wires, Matthew Fox

Electronic Theses and Dissertations

Actuator applications of shape memory alloys have typically been limited by their phase transformation temperatures to around 100 degrees C. However, recently with a focus on aerospace and turbomachinery applications there have been successful efforts to increase the phase transformation temperatures. Several of these alloy development efforts have involved ternary and quaternary elemental additions (e.g., Pt, Pd, etc.) to binary NiTi alloys. Experimentally assessing the effects of varying composition and thermo-mechanical processing parameters can be cost intensive, especially when expensive, high-purity elemental additions are involved. Thus, in order to save on development costs there is value in establishing a methodology …

Beliefs Of Graduate Students About Unstructured Computer Use In Face-To-Face Classes With Internet Access And Its Influence On Student Recall, Gregory Johnson

Electronic Theses and Dissertations

The use of computers equipped with Internet access by students during face-toface (F2F) class sessions is perceived as academically beneficial by a growing number of students and faculty members in universities across the United States. Nevertheless, some researchers suggest unstructured computer use detached from the immediate class content may negatively influence student participation, increase distraction levels, minimize recall of recently presented information, and decrease student engagement. This study investigates graduate students’ beliefs about computer use with Internet access during graduate face-to-face lecture classes in which computer use is neither mandated nor integrated in the class and the effect of such …

This study investigates the effects of institutional structure on the privacy rights regimes in the United States and the United Kingdom, from 2000-2006. The goal of this research is to analyze how variation in the institutional arrangements across these two countries allowed for more or less protection of privacy rights for citizens. Domestic terrorist attacks during the time period represent a catalyst for changes in police and government surveillance activities. Veto points literature provides the framework for institutional comparison. The first part of the research provides a discussion of the historical evolution of privacy rights in both states, focusing on …

The Clash Of Thoughts Within The Arab Discourse, Chadia Louai

Electronic Theses and Dissertations

The Clash of Civilization thesis by Samuel Huntington and the claims of other scholars such as Bernard Lewis reinforced the impression in the West that the Arab world is a homogeneous and rigid entity ready to clash with other civilizations. In fact, some in the West argue that world civilizations have religious characteristics, for that reason the fundamental source of conflict in this new world will be primarily cultural and religious. However, other scholars argue that there is no single Islamic culture but rather multiple types of political Islam and different perception of it. Therefore, the monolithic aspect of Islam …

Electronic Theses and Dissertations

This study examines the relationship between television shows and their corresponding websites featuring interactive message boards looking at the motivations and gratifications that users cited as reasons for being connected to a program. Information found provides knowledge on why viewers are drawn to TV, and what rewards they gain from the actions they perform beyond viewing the show. Specifically, this study examines if viewing a television show and discussing it on an online message board created the gratification of a greater sense of emotional attachment with the show, and if this sense of heightened emotional connection encouraged the board user …

Game Assessment For Miltary Application, Patricia Mcneese

Electronic Theses and Dissertations

The primary purpose of conducting this research was to establish game assessment guidelines and characteristics for integrating elected characteristics of games into ongoing instructional approaches. The cost of repurposing commercial-off-the-shelf (COTS) games could offer a considerably lower cost alternative than the cost of creating a new instructional game developed for a specific instructional goal. The McNeese Game Assessment Tool (MGAT), created for the assessment of games in this usability study, is currently in a beta stage and was found to have potential for future game assessment. The overall assessment indicated that the tool was effective in analyzing game products for …

Habitat-Specific Breeder Survival Of Florida Scrub-Jays: Inferences From Multistate Models, David R. Breininger, James D. Nichols, Geoffrey M. Carter, Donna M. Oddy

Faculty Bibliography 2000s

Quantifying habitat-specific survival and changes in habitat quality within disturbance-prone habitats is critical for understanding population dynamics and variation in fitness, and for managing degraded ecosystems. We used 18 years of color-banding data and multistate capture-recapture models to test whether habitat quality within territories influences survival and detection probability of breeding Florida Scrub-Jays (Aphelocoma coerulescens) and to estimate bird transition probabilities from one territory quality state to another. Our study sites were along central Florida's Atlantic coast and included two of the four largest metapopulations within the species range. We developed Markov models for habitat transitions and compared these to …

The Longin Domain Regulates The Steady-State Dynamics Of Sec22 In Plasmodium Falciparum, Lawrence Ayong, Avanthi Raghavan, Timothy G. Schneider, Theodore F. Taraschi, David A. Fidock, Debopam Chakrabarti

Faculty Bibliography 2000s

The specificity of vesicle-mediated transport is largely regulated by the membrane-specific distribution of SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein receptor) proteins. However, the signals and machineries involved in SNARE protein targeting to the respective intracellular locations are not fully understood. We have identified a Sec22 ortholog in Plasmodium falciparum (PfSec22) that contains an atypical insertion of the Plasmodium export element within the N-terminal longin domain. This Sec22 protein partially associates with membrane structures in the parasitized erythrocytes when expressed under the control of the endogenous promoter element. Our studies indicate that the atypical longin domain contains signals that are required …

Mcp-1 (Monocyte Chemotactic Protein-1)-Induced Protein, A Recently Identified Zinc Finger Protein, Induces Adipogenesis In 3t3-L1 Pre-Adipocytes Without Peroxisome Proliferator-Activated Receptor Gamma, Craig W. Younce, Asim Azfer, Pappachan E. Kolattukudy

Faculty Bibliography 2000s

Adipogenesis is a key differentiation process relevant to obesity and associated diseases such as type 2 diabetes. This process involves temporally regulated genes controlled by a set of transcription factors, CCAAT/enhancer-binding proteins (C/EBP) beta, C/EBP delta, and C/EBP alpha and peroxisome proliferator-activated receptor gamma (PPAR gamma). Currently, PPAR gamma is universally accepted as the master regulator that is necessary and sufficient to induce adipogenesis as no known factor can induce adipogenesis without PPAR gamma. We present evidence that a novel zinc finger protein, MCP-1-induced protein (MCPIP), can induce adipogenesis without PPAR gamma. Classical adipogenesis-inducing medium induces MCP-1 production and expression …

Inhibition Of Selenium Metabolism In The Oral Pathogen Treponema Denticola, Sarah Jackson-Rosario, William T. Self

Faculty Bibliography 2000s

In this report we provide evidence that the antimicrobial action of stannous salts and a gold drug, auranofin, against Treponema denticola is mediated through inhibition of the metabolism of selenium for synthesis of selenoproteins.

Polyamine Transport As A Target For Treatment Of Pneumocystis Pneumonia, Chung-Ping Liao, Otto Phanstiel Iv, Mark E. Lasbury, Chen Zhang, Shoujin Shao, Pamela J. Durant, Bi-Hua Cheng, Chao-Hung Lee

Faculty Bibliography 2000s

Polyamine levels are greatly increased in alveolar macrophages (AMs) during Pneumocystis pneumonia (PCP), leading to increased production of H(2)O(2), which causes AMs to undergo apoptosis. One of the mechanisms by which polyamine levels in AMs are elevated is enhanced uptake of exogenous polyamines. In this study, the possibility of targeting polyamine uptake as a treatment for PCP was examined. Four anthracene- and one benzene-polyamine conjugates that are potential polyamine transport inhibitors, including N1-anthracen-9-ylmethylbutane-1,4-diamine; N-(4-aminobutyl)-N-anthracen-9-ylmethylbutane-1,4-diamine; N-[4-(4-aminobutylamino)butyl]-N-anthracen-9-ylmethylbutane-1,4- diamine; N-(4-amino-butyl)-N'-(10-{[4-(4-aminobutylamino)butylamino]-methyl}anthracen-9-ylmethyl)butane-1,4-diamine (44-Ant-44); and benzene-polyamine conjugate N-(4-amino-butyl)-N'-(4-{[4-(4-amino-butylamino)butylamino]-methyl} benzyl)butane-1,4-diamine (44Bn-44), were tested. Compounds 44-Ant-44 and 44-Bn-44 were found to have a very low toxicity to AMs …

Iron In Arterial Plaque: A Modifiable Risk Factor For Atherosclerosis, Jerome L. Sullivan

Faculty Bibliography 2000s

It has been proposed that iron depletion protects against cardiovascular disease. There is increasing evidence that one mechanism for this protection may involve a reduction in iron levels within atherosclerotic plaque. Large increases in iron concentration are seen in human atherosclerotic lesions in comparison to levels in healthy arterial tissue. In animal models, depletion of lesion iron levels in vivo by phlebotomy, systemic iron chelation treatment or dietary iron restriction reduces lesion size and/or increases plaque stability. A number of factors associated with increased arterial disease or increased cardiovascular events is also associated with increased plaque iron. In rats, infusion …

Evidence For An Ancient Adaptive Episode Of Convergent Molecular Evolution, Todd A. Castoe, A. P. Jason De Koning, Hyun-Min Kim, Wanjun Gu, Brice P. Noonan, Gavin Naylor, Zhi J. Jiang, Christopher L. Parkinson, David D. Pollock

Faculty Bibliography 2000s

Documented cases of convergent molecular evolution due to selection are fairly unusual, and examples to date have involved only a few amino acid positions. However, because convergence mimics shared ancestry and is not accommodated by current phylogenetic methods, it can strongly mislead phylogenetic inference when it does occur. Here, we present a case of extensive convergent molecular evolution between snake and agamid lizard mitochondrial genomes that overcomes an otherwise strong phylogenetic signal. Evidence from morphology, nuclear genes, and most sites in the mitochondrial genome support one phylogenetic tree, but a subset of mostly amino acid-altering substitutions ( primarily at the …

The Homocysteine-Inducible Endoplasmic Reticulum Stress Protein Counteracts Calcium Store Depletion And Induction Of Ccaat Enhancer-Binding Protein Homologous Protein In A Neurotoxin Model Of Parkinson Disease, Srinivasulu Chigurupati, Zelan Wei, Cherine Belal, Myrian Vandermey, George A. Kyriazis, Thiruma V. Arumugam, Sic L. Chan

Faculty Bibliography 2000s

The endoplasmic reticulum (ER) is a key organelle regulating intracellular Ca(2+) homeostasis. Oxidants and mitochondria-derived free radicals can target ER-based Ca(2+) regulatory proteins and cause uncontrolled Ca(2+) release that may contribute to protracted ER stress and apoptosis. Several ER stress proteins have been suggested to counteract the deregulation of ER Ca(2+) homeostasis and ER stress. Here we showed that knockdown of Herp, an ubiquitin-like domain containing ER stress protein, renders PC12 and MN9D cells vulnerable to 1-methyl-4-phenylpyridinium-induced cytotoxic cell death by a mechanism involving up-regulation of CHOP expression and ER Ca(2+) depletion. Conversely, Herp overexpression confers protection by blocking 1-methyl-4-phenylpyridinium-induced …
