Florida's Paradox Of Progress: An Examination Of The Origins, Construction, And Impact Of The Tamiami Trail, Mark Schellhammer Jan 2012

Florida's Paradox Of Progress: An Examination Of The Origins, Construction, And Impact Of The Tamiami Trail, Mark Schellhammer

Electronic Theses and Dissertations

This study illustrates the impact of the Tamiami Trail on the people and environment of South Florida through an examination of the road’s origins, construction and implementation. By exploring the motives behind building the highway, the subsequent assimilation of indigenous societies, the drastic population growth that occurred as a result of a propagated “Florida Dream”, and the environmental decline of the surrounding Everglades, this analysis reveals that the Tamiami Trail is viewed today through a much different context than that of the road’s builders and promoters in the early twentieth century. While construction projects that aim to prevent, or limit …


Rock-A-Buy Baby: Consumerism By New, First-Time Mothers, Sara Afflerback Jan 2012

Rock-A-Buy Baby: Consumerism By New, First-Time Mothers, Sara Afflerback

Electronic Theses and Dissertations

Rock-a-Buy Baby: Consumerism by New, First-Time Mothers, is the first known sociological exploration of need-based consumption for babies, despite the baby gear industry being a $6-billion-dollar business (whattoexpect.com). Data stemmed from qualitative, semistructured interviews with new, first-time mothers (3 months – 1 year postpartum) conducted within participants‘ households. The insights gained from the present study tell us a great deal about the ―needs‖ that predominantly white, middle-class mothers socially constructed in anticipation of their first child, and the consumptive behaviors used to accomplish these "needs." Respondents had turned to similar resources (other mothers, online forums, consumer reports, books, magazines, etc.) …


Signals Delivered By Interleukin-7 Regulate The Activities Of Bim And Jund In T Lymphocytes, Shannon Moore Ruppert Jan 2012

Signals Delivered By Interleukin-7 Regulate The Activities Of Bim And Jund In T Lymphocytes, Shannon Moore Ruppert

Electronic Theses and Dissertations

Interleukin-7 (IL-7) is an essential cytokine for lymphocyte growth that has the potential for promoting proliferation and survival. While the survival and proliferative functions of IL-7 are well established, the identities of IL-7 signaling components in pathways other than JAK/STAT, that accomplish these tasks remain poorly defined. To this end, we used IL-7 dependent T-cells to examine those components necessary for cell growth and survival. Our studies revealed two novel signal transducers of the IL-7 growth signal: BimL and JunD. IL-7 promoted the activity of JNK (Jun N-terminal Kinase), and that JNK, in turn, drove the expression of JunD, a …


Between Words: Popular Culture And The Rise Of Print In Seventeenth Century England, Christie Schneck Jan 2012

Between Words: Popular Culture And The Rise Of Print In Seventeenth Century England, Christie Schneck

Electronic Theses and Dissertations

Seventeenth century England was forced to come to terms with events such as the Civil War and the regicide of King Charles I, in the midst of contending with the cultural changes brought upon by print culture, the effects of which appeared throughout all aspects of English society. These changes helped form a relationship between print and oral culture, one of negotiation among the producers and regulators of work and the society consuming the works. The discussion of this negotiation has led to varying conclusions concerning the true impact of printed materials on English society and culture, all of which …


Gender Bias In The Technical Disciplines, Jessica Lynn Campbell Jan 2012

Gender Bias In The Technical Disciplines, Jessica Lynn Campbell

Electronic Theses and Dissertations

This study investigates how women are affected by gender bias in the workplace. Despite the increasing numbers of women in the workforce, women are still under-represented and under-valued in workplaces, which, in part, is due to their gender stereotype. This study demonstrates how gender bias in the workplace has been proven to limit women in their careers and potential in their occupational roles. The media’s negative depiction of women in their gender stereotype reinforces and perpetuates this image as a cultural norm in society. Women both conform and are judged and evaluated according to their weak and submissive gender stereotype. …


Metaphoric Competence As A Means To Meta-Cognitive Awareness In First-Year Composition, David T. Dadurka Jan 2012

Metaphoric Competence As A Means To Meta-Cognitive Awareness In First-Year Composition, David T. Dadurka

Electronic Theses and Dissertations

A growing body of writing research suggests college students’ and teachers’ conceptualizations of writing play an important role in learning to write and making the transition from secondary to post-secondary academic composition. First-year college writers are not blank slates; rather, they bring many assumptions and beliefs about academic writing to the first-year writing classroom from exposure to a wide range of literate practices throughout their lives. Metaphor acts as a way for scholars to trace students’ as well as their instructors’ assumptions and beliefs about writing. In this study, I contend that metaphor is a pathway to meta-cognitive awareness, mindfulness, …


The Foods And Crops Of The Muisca: A Dietary Reconstruction Of The Intermediate Chiefdoms Of Bogota (Bacata) And Tunja (Hunza), Colombia, Jorge Luis Garcia Jan 2012

The Foods And Crops Of The Muisca: A Dietary Reconstruction Of The Intermediate Chiefdoms Of Bogota (Bacata) And Tunja (Hunza), Colombia, Jorge Luis Garcia

Electronic Theses and Dissertations

The Muisca people of the Eastern Cordillera of Colombia had an exceptionally complex diet, which is the result of specific subsistence strategies, environmental advantages, and social restrictions. The distinct varieties of microclimates, caused by the sharp elevations in this part of the Andes, allows for a great biodiversity of plants and animals that was accessible to the native population. The crops of domesticated and adopted plants of the Muisca include a wide variety of tubers, cereals, fruits, and leaves that are described in detail in this thesis. The Muisca used an agricultural method known as microverticality where the different thermic …

Measuring Trust In Virtual Worlds: Avatar-Mediated Self-Disclosure, Amanda M. Surprenant

Electronic Theses and Dissertations

This study investigated the development of trust between strangers interacting via avatars in virtual worlds. The first part of the study analyzed perceived trustworthiness based on the visual appearance of avatars; the second part makes observations of two strangers self-disclosing information via avatars in a virtual world; the third part analyzed an experimental situation of two individuals interacting via avatars, where avatar appearance was changed and participants were recruited based on their experience with interacting with others via avatars. Findings showed that perceived trustworthiness does vary based on the visual appearance of the avatar. A positive relationship was found for …


Establishing Difference: The Gendering And Racialization Of Power In Genocide, Erin E. Welsh Jan 2012

Establishing Difference: The Gendering And Racialization Of Power In Genocide, Erin E. Welsh

Electronic Theses and Dissertations

This thesis is designed to delve deeper into perceptions of identity, specifically gender and racial identity, the power relationship that emerges as each of these switches is reached in the progression towards genocide, and the effects of these perceptions during and after the genocide takes place. The primary question addressed is whether the power relationship that emerges as a result of these pre-genocidal stages becomes gendered and racialized due to perceptions rooted in a male-dominated hierarchy and a belief in the superiority of one ethnicity over another. The primary goal of this thesis is to analyze the power relationship in …


Human Spaceflight Decision-Making As A Potential Well Problem, Ari Litwin Jan 2012

Human Spaceflight Decision-Making As A Potential Well Problem, Ari Litwin

Electronic Theses and Dissertations

This study investigates funding within the US human spaceflight program in the timeperiod from 2004 to 2012. The approach taken employed the “potential well” model from physical science. The potential well model constrains any physical body trapped within it, and similarly a political “funding well” will constrain all programmatic decision-making. Two potential well models are employed, one represents classical physics while the other represents quantum physics. Since each model results in motion with certain properties, it can be seen if funding decisions also exhibit similar properties. In physics, the bifurcation between the classical world of aggregate bodies and the quantum …


Ritual Use Of The Human Form: A Contextual Analysis Of The "Charlie Chaplin" Figure In The Maya Lowlands, Lisa M. Lomitola Jan 2012

Ritual Use Of The Human Form: A Contextual Analysis Of The "Charlie Chaplin" Figure In The Maya Lowlands, Lisa M. Lomitola

Electronic Theses and Dissertations

Small anthropomorphic figures, most often referred to as “Charlie Chaplins,” appear in ritual deposits throughout the ancient Maya sites of Belize during the late Preclassic and Early Classic Periods and later, throughout the Petén region of Guatemala. Often these figures appear within similar cache assemblages and are carved from “exotic” materials such as shell or jade. This thesis examines the contexts in which these figures appear and considers the wider implications for commonly held ritual practices throughout the Maya lowlands during the Classic Period and the similarities between “Charlie Chaplin” figures and anthropomorphic figures found in ritual contexts outside of …


Italian-American Ethnic Concentration, Informal Social Control, And Urban Violent Crime: A Defended Neighborhoods Approach, Hollianne Elizabeth Marshall Jan 2012

Italian-American Ethnic Concentration, Informal Social Control, And Urban Violent Crime: A Defended Neighborhoods Approach, Hollianne Elizabeth Marshall

Electronic Theses and Dissertations

This study examines the impact of white ethnic concentration on robbery and homicide in Chicago and New York City. As one of the first to disaggregate white ethnic populations, this study has the expectation that Italian-American concentration will have a stronger influence on robbery and homicide than any other white ethnic concentrations. This study is founded on prior qualitative research suggesting that the reputation of Italian-Americans influences the behavior of outsiders in their communities. The data show there is a significant and negative relationship between Italian-American concentration and the violent crimes robbery and homicide. This relationship only exists for white …


The Effects Of Phosphatidylserine On Reaction Time And Cognitive Function Following An Exercise Stress, Adam John Wells Jan 2012

The Effects Of Phosphatidylserine On Reaction Time And Cognitive Function Following An Exercise Stress, Adam John Wells

Electronic Theses and Dissertations

Phosphatidylserine (PS) is an endogenously occurring phospholipid that has been shown to have cognition and mood enhancing properties in humans, possibly through its role as an enzyme co-factor in cellular signal transduction. Specifically, PS has been identified as activator of classical isoforms of protein kinase C, an enzyme known to be involved in the growth and differentiation of neural cells, and is therefore thought to play a role in the protection of neurons. The purpose of this study was to examine the effects of supplementation with PS and caffeine on measures of cognition, reaction time and mood prior to and …


Phosphatidic Acid Increases Lean Body Tissue And Strength In Resistance Trained Men, David Williams Jan 2012

Phosphatidic Acid Increases Lean Body Tissue And Strength In Resistance Trained Men, David Williams

Electronic Theses and Dissertations

Phosphatidic Acid (PA) is a natural phospholipid compound derived from lecithin which is commonly found in egg yolk, grains, fish, soybeans, peanuts and yeast. It has been suggested that PA is involved in several intracellular processes associated with muscle hypertrophy. Specifically, PA has been reported to activate protein synthesis through the mammalian target of rapamycin (mTOR) signaling pathway and thereby may enhance the anabolic effects of resistance training. To our knowledge, no one has examined the effect of PA supplementation in humans while undergoing a progressive resistance training program. To examine the effect of PA supplementation on lean soft tissue …


Thematic Patterns In Millennial Heavy Metal: A Lyrical Analysis, Evan Chabot Jan 2012

Thematic Patterns In Millennial Heavy Metal: A Lyrical Analysis, Evan Chabot

Electronic Theses and Dissertations

Research on heavy metal music has traditionally been framed by deviant characterizations, effects on audiences, and the validity of criticism. More recently, studies have neglected content analysis due to perceived homogeneity in themes, despite evidence that the modern genre is distinct from its past. As lyrical patterns are strong markers of genre, this study attempts to characterize heavy metal in the 21st century by analyzing lyrics for specific themes and perspectives. Citing evidence that the “Millennial” generation confers significant developments to popular culture, the contemporary genre is termed “Millennial heavy metal” throughout, and the study is framed accordingly. Utilizing prominent …


Expression Of Lipase From Mycobacterium Tuberculosis In Nicotiana Tobacum And Lactuca Sativa Chloroplasts, Bethany Lloyd Jan 2012

Expression Of Lipase From Mycobacterium Tuberculosis In Nicotiana Tobacum And Lactuca Sativa Chloroplasts, Bethany Lloyd

Electronic Theses and Dissertations

Tuberculosis (TB), caused by the bacterium Mycobacterium tuberculosis (M. tuberculosis), is a global threat and the leading cause of death among individuals infected with HIV. TB treatment requires multi-drug cocktails, due to the increasing rates of drug resistance of the bacterium. With multi-drug cocktails, strains have been documented to be resistant to all major drugs in the fight against TB. Since the strains are drug resistant, it calls for an increasing need for vaccine and treatment development for the purpose of preventing and managing the disease. The most widely distributed vaccine against TB is Bacillus Calmette-Gue´rin (BCG). Apart from being …

Cerium Oxide Nanoparticles Act As A Unique Catalyst And Scavenge Nitric Oxide And Peroxynitrite And Decrease Rns In Vitro And In Vivo, Janet Dowding Jan 2012

Cerium Oxide Nanoparticles Act As A Unique Catalyst And Scavenge Nitric Oxide And Peroxynitrite And Decrease Rns In Vitro And In Vivo, Janet Dowding

Electronic Theses and Dissertations

Cerium oxide nanoparticles (CeO2 NPs)(nanoceria) have been shown to possess a substantial oxygen storage capacity via the interchangeable surface reduction and oxidation of cerium atoms, cycling between the Ce4+ and Ce3+ redox states. Reduction of Ce4+ to Ce3+ causes oxygen vacancies or defects on the surface of the crystalline lattice structure of the particles, generating a cage for redox reactions to occur. The study of the chemical and biological properties of CeO2 NPs has expanded recently, and the methods used to synthesize these materials are also quite diverse. This has led to a plethora of studies describing various preparations of …


A Study Of The Degradative Capabilities Of The Bimetallic System: Mg(Pd/C) As Applied In The Destruction Of Decafluoropentane, An Environmental Contaminant, Douglas Tomlin Jan 2012

A Study Of The Degradative Capabilities Of The Bimetallic System: Mg(Pd/C) As Applied In The Destruction Of Decafluoropentane, An Environmental Contaminant, Douglas Tomlin

Electronic Theses and Dissertations

Pollution from hydrofluorocarbons (HFC) poses a serious challenge to the environmental community. Released from industrial operations, they have contaminated both the atmosphere and groundwater and are considered persistent in both media.1 For over the past 20 years, the practice of synthesizing hydrofluorocarbons as alternatives to chlorofluorocarbons (CFC) has been conducted in an effort to reverse the effects of stratospheric ozone layer depletion. 2,3 However, in doing so these new fluorinated compounds exhibited an unexpected property as a potent global warming greenhouse gas (GHG) with radiative forcing potentials in the range of 100 to 10,000 equivalents greater than carbon dioxide.4 Conversely, …


Florida's Cattle Culture: Ethos And Enterprise In The Sunshine State, Corinne E. Zellner Jan 2012

Florida's Cattle Culture: Ethos And Enterprise In The Sunshine State, Corinne E. Zellner

Electronic Theses and Dissertations

Cattle ranching has been of major significance to Florida since the 16th century; however, few are aware of the historic, ecologic, economic and cultural influence of this industry. This study investigates the origins and impacts of the traditional customs and practices of Florida’s cattle ranchers, who preserve and reinvent this rich heritage today. Ranchers live closely with the land and their animals and, due to the often-uncertain and cyclical nature of the business, must possess resourcefulness and initiative to prosper. The image of the stoic cowboy has long been associated with the American West, yet before longhorn cattle ever crossed …


Conservation And Population Biology: Genetics, Demography And Habitat Requirements Of The Atlantic Coast Beach Mice, Haakon Myklevoll Kalkvik Jan 2012

Conservation And Population Biology: Genetics, Demography And Habitat Requirements Of The Atlantic Coast Beach Mice, Haakon Myklevoll Kalkvik

Electronic Theses and Dissertations

The conservation biology field seeks to preserve biodiversity and the processes shaping that variation. Conservation biology is intimately tied to evolutionary research, in order to identify evolutionary distinct lineages that may be in danger of disappearing. Interestingly, patterns and processes of lineage divergence and persistence change with respect to spatial and temporal scale. I seek to evaluate biodiversity, the factors that have shaped this heterogeneity, and how this variability persists. To accomplish this I used a phylogeographic approach as well as niche and population modeling on the Peromyscus maniculatus species group found widely distributed in North America. My emphasis was …

This thesis is a record of this video’s progression, from development to …


Manipulation Of Host Signal Transduction Pathways And Cytoskeleton Functions By Invasive Bacterium Listeria Monocytogenes And Chlamydia Trachomatis, Shahanawaz Jiwani Jan 2012

Manipulation Of Host Signal Transduction Pathways And Cytoskeleton Functions By Invasive Bacterium Listeria Monocytogenes And Chlamydia Trachomatis, Shahanawaz Jiwani

Electronic Theses and Dissertations

Infectious disease remains one of the leading causes of morbidity and mortality worldwide. Many bacteria that cause disease have the capacity to enter into eukaryotic cells such as epithelial cells and tissue macrophages. Gaining access into the intracellular environment is one of the most critical steps in their survival and/or in pathogenesis. The entry mechanisms employed by these organisms vary considerably, but most mechanisms involve sabotaging and manipulating host cell functions. Invasion of epithelial cells involves triggering host signal transduction mechanisms to induce cytoskeleton rearrangement, thereby facilitating bacterial uptake. My work focuses on understanding the molecular mechanisms employed by bacterial …


Beyond Building A Tree: Phylogeny Of Pitvipers And Exploration Of Evolutionary Patterns, Allyson Fenwick Jan 2012

Beyond Building A Tree: Phylogeny Of Pitvipers And Exploration Of Evolutionary Patterns, Allyson Fenwick

Electronic Theses and Dissertations

As generic and higher-scale evolutionary relationships are increasingly well understood, systematists move research in two directions: 1) understanding specieslevel relationships with dense taxon sampling, and 2) evaluating evolutionary patterns using phylogeny. In this study I address both foci of systematic research using pitvipers, subfamily Crotalinae. For direction one, I evaluate the relationships of 96% of pitvipers by combining independent sets of molecular and phenotypic data. I find the inclusion of species with low numbers of informative characters (i.e. less than 100) negatively impacts resolution of the phylogeny, and the addition of independent datasets has no effect on or a small …


Assessment Of Molecular Interactions Via Magnetic Relaxation: A Quest For Inhibitors Of The Anthrax Toxin, Oscar Santiesteban Jan 2012

Assessment Of Molecular Interactions Via Magnetic Relaxation: A Quest For Inhibitors Of The Anthrax Toxin, Oscar Santiesteban

Electronic Theses and Dissertations

Anthrax is severe disease caused by the gram-positive Bacillus anthracis that can affect humans with deadly consequences. The disease propagates via the release of bacterial spores that can be naturally found in animals or can be weaponized and intentionally released into the atmosphere in a terrorist attack. Once inhaled, the spores become activated and the anthrax bacterium starts to reproduce and damage healthy macrophages by the release of the anthrax toxin. The anthrax toxin is composed of three virulent factors: (i) anthrax protective antigen (APA), (ii) anthrax lethal factor (ALF), and (iii) anthrax edema factor (AEF) that work in harmony …


Trade Secrets, Rachel Kolman Jan 2012

Trade Secrets, Rachel Kolman

Electronic Theses and Dissertations

Trade Secrets is a collection of fourteen short stories that explores characters falling in and out of relationships and coping in unusual and even comedic ways. These characters are often obsessive and do not trust one another. They think life is funny, and discover that love is funny, and yeah, sex can be funny too. They don’t feel the right things when they’re supposed to. They find love, and lose love. They find hope, and lose hope. They escape sometimes, but more often are unable to go anywhere. These stories consider relationships through the disconnection between reality and fantasy, exploring …


Somatechnologies Of Body Size Modification: Posthuman Embodiment And Discourses Of Health, Meghan Griffin Jan 2012

Somatechnologies Of Body Size Modification: Posthuman Embodiment And Discourses Of Health, Meghan Griffin

Electronic Theses and Dissertations

This project focuses on persistent gaps in philosophies of the body: the enduring mindbody divide in accounts of phenomenology, the unfulfilled promises of representing and inhabiting the body in online and virtual spaces, and the difference between health as quantified in medical discourse versus health as lived experience. These tensions are brought to light through the electronic food journal genre where the difficulty in capturing pre-noetic, outsideconsciousness aspects of experience and embodied health are thrown into relief against circulating cultural discourses surrounding health, body size, self-surveillance, and self-care. The electronic food journal genre serves as a space for users to …


Hidden Variable, Heather Harms Jan 2012

Hidden Variable, Heather Harms

Electronic Theses and Dissertations

Hidden Variable is a novel that blends linear storytelling with the novel-in-stories form. It poses questions about the nature of identity as well as the feasibility of personal power, particularly with respect to disorders of the mind. Darla Pierson, the novel’s protagonist, is a woman in crisis. She is steeped in selfloathing brought on by the knowledge that she has, in effect, become her dead father—a genius with an epic libido, habitually using and discarding people. Her father has another habit that Darla doesn’t share: being struck by lightning. After the second strike kills him, Darla makes a conscious attempt …


A Discussion Of Robert Schumann's Compositional Process In The Song Cycle Frauenliebe Und -Leben, Brittany Monique Denham Jan 2012

A Discussion Of Robert Schumann's Compositional Process In The Song Cycle Frauenliebe Und -Leben, Brittany Monique Denham

Electronic Theses and Dissertations

Robert Schumann’s compositional work during 1840 stands out as an unexpected turn of events. With relatively no background composing songs, Schumann suddenly produced a plethora of widely successful and monetarily lucrative songs all within one year. Perhaps most fascinating was the amount of detail Schumann placed into each song. This detail can be seen in the sketches which include the composer’s handwritten edits in both the piano and vocal scores. With a focus on Schumann’s song cycle, Frauenliebe und -leben the qualities of Schumann’s songs and the compositional process used to create the songs’ final versions are examined through this …
