A Framework For Process Data Collection, Analysis, And Visualization In Construction Projects, Reza Akhavian

Electronic Theses and Dissertations

Automated data collection, simulation and visualization can substantially enhance the process of designing, analysis, planning, and control of many engineering processes. In particular, managing processes that are dynamic in nature can significantly benefit from such techniques. Construction projects are good examples of such processes where a variety of equipment and resources constantly interact inside an evolving environment. Management of such settings requires a platform capable of providing decision-makers with updated information about the status of project entities and assisting site personnel making critical decisions under uncertainty. To this end, the current practice of using historical data or expert judgments as …

Placing Birds On A Dynamic Evolutionary Map: Using Digital Tools To Update The Evolutionary Metaphor Of The "Tree Of Life", Sonia Stephens Jan 2012

Placing Birds On A Dynamic Evolutionary Map: Using Digital Tools To Update The Evolutionary Metaphor Of The "Tree Of Life", Sonia Stephens

Electronic Theses and Dissertations

This dissertation describes and presents a new type of interactive visualization for communicating about evolutionary biology, the dynamic evolutionary map. This web-based tool utilizes a novel map-based metaphor to visualize evolution, rather than the traditional "tree of life." The dissertation begins with an analysis of the conceptual affordances of the traditional tree of life as the dominant metaphor for evolution. Next, theories from digital media, visualization, and cognitive science research are synthesized to support the assertion that digital media tools can extend the types of visual metaphors we use in science communication in order to overcome conceptual limitations of traditional …

Age As A Factor In Inter-Tissue Spacing Of Stable Carbon Isotope Values In Juvenile Human Remains From The Dakhleh Oasis, Egypt, Annie Laurie Norris

Electronic Theses and Dissertations

Although stable isotope analysis is routinely utilized in bioarchaeology and relies on principles that are well-understood, there are still fundamental issues that have not been thoroughly investigated. This thesis examines the relationship between inter-tissue spacing of carbon stable isotope values (δ13C) and age in juvenile human remains. Analyses of tissues within the same individual reveal disparate isotopic values for a variety of physiological and biological reasons discussed herein. This project examines the distance between the δ13C values in bone collagen, skin, hair, and nail, and examines how these distances vary between different age groups, utilizing data collected from 52 well-preserved …

Biochemical Studies Of Abce1, Lynn Sims Jan 2012

Biochemical Studies Of Abce1, Lynn Sims

Electronic Theses and Dissertations

The growth and survival of all cells require functional ribosomes that are capable of protein synthesis. The disruption of the steps required for the function of ribosomes represents a potential future target for pharmacological anti-cancer therapy. ABCE1 is an essential Fe-S protein involved in ribosomal function and is vital for protein synthesis and cell survival. Thus, ABCE1 is potentially a great therapeutic target for cancer treatment. Previously, cell biological, genetic, and structural studies uncovered the general importance of ABCE1, although the exact function of the Fe-S clusters was previously unclear, only a simple structural role was suggested. Additionally, due to …

Effect Of Predation Risk And Food Availability On Parental Care And Nest Survival In Suburban And Wildland Florida Scrub-Jays, Joseph M. Niederhauser Jan 2012

Effect Of Predation Risk And Food Availability On Parental Care And Nest Survival In Suburban And Wildland Florida Scrub-Jays, Joseph M. Niederhauser

Electronic Theses and Dissertations

Individual organisms often use cues from their natural environments to determine many behavioral and life-history "decisions." These "decisions" are usually adaptive, i.e. a response to selection, because the environmental cues on which they are based reliably correlate with increased fitness over time. When the selected behavioral response to a natural cue no longer provides a fitness benefit, then selection for a new response may occur but individuals maintaining the previously selected response may suffer reduced survival and reproduction. Especially in human-modified landscapes individuals making a maladaptive behavioral or life-history choice based on those formerly reliable environmental cues may be faced …

Fine-Scale Geographic Variation Of Stable Isotope And Fatty Acid Signatures Of Three Fish Species In The Indian River Lagoon, Fl, Jennifer Fletcher Odom Jan 2012

Fine-Scale Geographic Variation Of Stable Isotope And Fatty Acid Signatures Of Three Fish Species In The Indian River Lagoon, Fl, Jennifer Fletcher Odom

Electronic Theses and Dissertations

The Indian River Lagoon, Florida, is a unique closed “bar built” estuary system that has little interchange with the Atlantic Ocean and which is home to many resident species. Three fish species were investigated to see if their isotopic and fatty acid signatures differed based on geographic location. The goal was to assess the degree of resolution of spatial variation that is possible when using stable isotope and fatty acid signature analysis to interpret feeding habits and potential linkages between feeding habits and health status. Spotted seatrout (n=40), pinfish (n=60) and white mullet (n=60) were collected over a 4 week …

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, …

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

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 …

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 …
