Air Traffic Controllers: Flying In The Face Of Danger? A Look Into The Effects Of The Time Of Day, Jason Boergerhoff

Theses and Dissertations

Since the events of September 11, this country has continued to grow and its commercial air travel along with it. As the number of passengers and planes increase, so must the skill and etermination of the air traffic controllers. They must be at their peak performance levels to ensure the flying public is handled safely and expeditiously. This study looks at the possible effects of the time of day. After defining time of day effects and giving some of the consequences of these effects, a look into the task of a controller was necessary. This study broke the task down …

Not Quite Natural: Stories From The Edges Of Humanity, Patrick Walters

Electronic Theses and Dissertations Archive

This thesis, entitled “Not Quite Natural: Stories From the Edges of Humanity,” is a collection of creative nonfiction essays. It features stories about people who exist on the fringes of the human experience, from a man who infects himself with hookworms in an effort to cure his severe allergies to a woman who discovers a deaf man who has no language. It also features stories about groups of people on the edges of the human experience, including a community that refuses to leave its town, even though a fire is burning a hundred and fifty feet beneath it and a …

Parental Involvement: A Qualitative Case Study Of Parent Involvement In Two Rural Mid-South Middle Schools, Tishsha Tanay Hopson

Electronic Theses and Dissertations Archive

The purpose of this qualitative case study was to gain a better understanding of what parental involvement means to parents and what influences them to become involved in a school. Joyce Epstein's Six Types of Parent Involvement Typology provided a guiding framework to assess terms and categories commonly used in parent involvement research. This study was guided by two research questions: What does parental involvement mean to parents? What influences parents to engage in parent involvement? The researcher conducted interviews, focus groups, and took field notes as primary sources of data to answer the two reserach questions.The researcher interviewed six …

"The Young Blood Hungers": Mapping Young Black Manhood In Marita Bonner's Frye Street Fiction, Rachel Leigh Smith

Electronic Theses and Dissertations Archive

Marita O. Bonner, early twentieth century African American public intellectual and creative writer, wrote particularly about the experiences of blacks in Chicago. Though most Bonner scholarship focuses primarily on her working class female characters, this study provides close readings of the young male figures in the short stories, "One Boy's Story," "The Makin's," "The Whipping," "There Were Three," "Tin Can," and "Nothing New." I analyze how these texts confront notions of family, personal identity, and violence, and how Bonner configures young life as a volatile liminal space of human development. As seen in Bonner's short stories and in her essay …

Osteoblast Precursors Respond To Cyclic Mechanical Compressive And Tensile Strains At The Bone-Implant Interface, Andrew Phillip Noblett

Electronic Theses and Dissertations Archive

Stromals cells, W-20-17, were subjected to daily 30 minute doses of 800microstrain at 1Hz for six consecutive days on a commercially pure titanium substrate with a custom 4-point-bend cell strain system to simulate the bone-implant interface in vivo. The loading schemes include continuous and intermittent (15minutes of strain, 15 minutes of rest, 15 minutes of strain) dosing in both compresssive and tensile strain. Cell lysates and media were collected after 12hrs on the plate and after 1, 3, and 6 days of straining. DNA, total protein, and ALP concentrations were assayed to assess the results of the different strains. Overall …

Modeling Light-Dark Cycle Memory In The Mammalian Scn, Benjamin L. Coffey

Electronic Theses and Dissertations Archive

The suprachiasmatic nuclei (SCN), the principal mammalian circadian oscillator, contain several thousand clock neurons that oscillate spontaneously with ~24-hour periods in its ventrolateral region. Without light, this network synchronizes through action potentials releasing VIP, compromising on a free-running period near 24 hours. We entrained Siberian hamsters to various light-dark cycles and tracked their activity into constant darkness showing that they retain memory for a particular light-dark cycle to which they were entrained before returning to their own free-running period. Using Leloup-Goldbeter mammalian clock neurons, we model the ventrolateral SCN network and show that light acting weakly upon a strongly rhythmic …

Engaging Rural Community Members As Problem Solvers: Application Of Health Communication To Improve The Quality Of Health Care In Southwest Uganda, Tesfa N. Alexander

Electronic Theses and Dissertations Archive

Using communication theories and anthropological models, I analyze the narratives of community members who are caretakers of children ages 5 and under in Southwest Uganda to situate rural community members as problem solvers whose insights can be used to inform sustainable and effective public health strategies that can lead to improved health outcomes. Throughout my analysis, I uncover themes and concepts from community members' narratives that demonstrate that health-seeking behaviors of rural community members are largely shaped by perceptions of interpersonal and social trust in local health care practitioners. Additionally, an analysis of discourse from patient-provider interactions in biomedical and …

Stochastic Simulation Of Human Pulmonary Blood Flow Based On Anatomic And Elasticity Data, Jun Shi

Electronic Theses and Dissertations Archive

In order to fully understand the function of the lungs, it is important to determine the transit time of the pulmonary circulation. However, a practical model to estimate the transit time is difficult to be found in literature, because of the high complexity of the whole pulmonary circulation system. This study developed a computing model of steady blood flow in human lungs based on detailed morphology and elasticity data by Huang et al (1996) [5], which incorporated a Diameter-Defined Strahler System to simulate a human lung branching system. A stochastic simulation approach was introduced. Considering Huang’s connectivity data between different …

Efficient Separation And Sensitive Detection Of Listeria Monocytogenes Using Magnetic Nanoparticles, Microfluidics And Interdigitated Microelectrode Based Impedance Immunosensor, Damira Ashimkhanovna Kanayeva

Graduate Theses and Dissertations

Listeria monocytogenes continues to be a major foodborne pathogen that causes food poisoning and sometimes death in immunosuppressed people and abortion in pregnant women. Nanoparticles have recently drawn attentions for use in immunomagnetic separation techniques due to their greater surface area/volume ratio and better stability against sedimentation in the absence of a magnetic field. Interdigitated microelectrodes and microfluidics make material transfer more efficient and biological/chemical interaction between the surface and solution phase much quicker. Magnetic nanoparticles (Fe3O4) with a 30 nm diameter were functionalized with rabbit anti-L. monocytogenes antibodies via biotin-streptavidin bonds and then amalgamated with target bacterial cells …

A Comparison Of Cumulative-Germination Response Of Cheatgrass (Bromus Tectorum L.) And Five Perennial Bunchgrass Species To Simulated Field-Temperature Regimes, Stuart P. Hardegree, Corey A. Moffet, Bruce A. Roundy, Thomas A. Jones, Stephen J. Novak, Patrick E. Clark, Frederick B. Pierson, Gerald N. Flerchinger

Biology Faculty Publications and Presentations

Cheatgrass (Bromus tectorum L.) has come to dominate millions of hectares of rangeland in the Intermountain western United States. Previous studies have hypothesized that one mechanism conferring a competitive advantage to this species is the ability to germinate rapidly at low temperatures in the fall, winter and spring and, therefore, initiate growth and establishment more rapidly than more desirable perennial bunchgrass species. In this experiment, we developed thermal-germination-response models for multiple seedlots of cheatgrass and five perennial grass species. We conducted sensitivity analysis on potentialcumulative- germination response to a 38-y simulation of field-variable conditions of seedbed temperature and moisture. …

Eighteen Microsatellite Loci Developed From Western Burrowing Owls (Athene Cunicularia Hypugaea), Brant C. Faircloth, Alexandra Title, Kevin Tan, Justin Welty, James R. Belthoff, Patricia Adair Gowaty

Biology Faculty Publications and Presentations

Western burrowing owls (Athene cunicularia hypugaea) are ground-dwelling owls distributed throughout western North America. Because of population declines, this species is considered endangered in Canada, and burrowing owls are listed as a species of conservation concern in states of the western USA. Korfanta et al. (2002) previously presented primers for seven microsatellite loci in burrowing owls. Parentage and relatedness studies require a larger number of markers for accuracy and precision. Here, we developed and characterized 18 additional microsatellite DNA loci, and we tested these loci in 23 individuals. The number of alleles per locus ranged from 2 to …

Evaluation Of Tetrachloroethene Dechlorination Under Low Ph Conditions In Microcosms And Enrichment Cultures, Michael Hickey

All Theses

Chlorinated ethenes are among the most prevalent groundwater contaminants found at hazardous waste sites throughout the United States. Two such sites are the Statesville FCX OU3 Superfund Site in North Carolina and the C-area at the Savannah River Site (SRS) in Aiken, SC. Both sites are contaminated with two of the more common chlorinated ethenes; tetrachloroethene (PCE) and trichloroethene (TCE). Anaerobic biological reductive dechlorination is an increasingly common treatment option. There are two main concerns as to the feasibility of this approach. The first is if the microbes are present that are needed for carrying out complete reductive dechlorination of …

Hybrid Nanomanufacturing Process For High-Rate Polymer Nanofiber Production, Chad T. Peterson

Department of Engineering Mechanics: Dissertations, Theses, and Student Research

Nanotechnology and nanomaterials have the potential to revolutionize existing and create entirely new industries. Unique physical, mechanical, chemical, and biological properties of nanomaterials have been extensively documented in the last two decades. However, most nanomaterials are discontinuous in nature, creating problems with their processing and manipulation into devices and raising health concerns. Continuous nanofibers represent an emerging class of nanomaterials with critical advantages to applications. Continuous nanofibers are readily produced by electrospinning process comprising spinning polymer solutions in high electric fields. Electrospinning is a very economic top-down nanomanufacturing process that has been used to produce ultrafine continuous nanofibers from several …

An Nadph-Dependent Genetic Switch Regulates Plant Infection By The Rice Blast Fungus, Richard A. Wilson, Robert P. Gibson, Cristian Quispe, Jennifer A. Littlechild, Nicholas J. Talbot

Fungal Molecular Plant-Microbe Interactions

To cause rice blast disease, the fungus Magnaporthe oryzae breaches the tough outer cuticle of the rice leaf by using specialized infection structures called appressoria. These cells allow the fungus to invade the host plant and proliferate rapidly within leaf tissue. Here, we show that a unique NADPH-dependent genetic switch regulates plant infection in response to the changing nutritional and redox conditions encountered by the pathogen. The biosynthetic enzyme trehalose-6-phosphate synthase (Tps1) integrates control of glucose-6-phosphate metabolism and nitrogen source utilization by regulating the oxidative pentose phosphate pathway, the generation of NADPH, and the activity of nitrate reductase. We report …

The Life Space Interview In Therapeutic Crisis Intervention: An Action Research Study On Its Implementation In A Suburban High School, Susan J. Flood

Education Doctoral

Students with emotional and behavioral disabilities experience less school success than any other subgroup of students. The educational system is the only institution mandated to serve children and youth with emotional disabilities; however, for approximately 51% of these students, the educational experience ends with the decision to drop out of school. For novice teachers, an early experience with a disruptive student can end their career, while even experienced teachers may feel daunted by student behavior. Educators are searching for more effective means of working with students with emotional needs whose unresolved conflicts can escalate into classroom disruption, lack of student …

Economic Writing On The Pressing Problems Of The Day: The Roles Of Moral Intuition And Methodological Confusion, Julie A. Nelson

Economics Faculty Publication Series

Economists are often called on to help address pressing problems of the day, yet many economists are uncomfortable about disclosing the values that they bring to this work. This essay explores how an inadequate understanding of the role of methodology, as related to ethics and human emotions of concern, underlies this reluctance and compromises the quality of economic advice. The tension between caring about the problems, on the one hand, and writing within the existing culture of the discipline, on the other, are illustrated with examples from U.S. policymaking, behavioral economics, and the economics of climate change and global poverty. …
