Living Through Terror And Terror Through Living: The Biopolitical Dimensions Of Religion, Security, And Terrorism, Donnie Featherston
Living Through Terror And Terror Through Living: The Biopolitical Dimensions Of Religion, Security, And Terrorism, Donnie Featherston
Electronic Theses and Dissertations
Recent emphasis and attention by thinkers, media pundits, and politicians on terrorism requires new, critical evaluation of the processes by which terrorism is understood. By investigating the concept of biopolitics, as developed specifically through Michel Foucault and Giorgio Agamben, new insights into the interactions between terrorism, politics, and religion can emerge. Most notably, the attempts to explain terror as simply an economic problem, an excessive form of violence, and/or as religious fervency gone awry rely on embedded biopolitical concepts. The continual attempts to solve terrorism through increased biopolitical strategies, thereby making terrorism a problem for biopolitics, only further substantiate the …
The Investigation Of Lactoferrin Nitration: Quantification, Function, And Inhibition, Amani Yahya Alhalwani
The Investigation Of Lactoferrin Nitration: Quantification, Function, And Inhibition, Amani Yahya Alhalwani
Electronic Theses and Dissertations
Lactoferrin (LF) is an iron-binding glycoprotein of molecular mass ca. 80 kDa that is predominantly found in mammalian body fluids. Lactoferrin is a multifunctional protein that has a wide range of properties such as antibacterial, antiviral, anti-inflammatory, and anti-allergic functions. Tyrosine residues in the protein play a part in many lactoferrin functions. Protein tyrosine nitration modification represents an oxidative and nitrosative stress process which can be caused by the exposure of proteins to oxidants from air pollution or disease. Understanding the way nitrated lactoferrin interacts with the biochemical environment of the body is thus important to the broader goal of …

Probing The Effects Of Substrate Stiffness On Astrocytes Mechanics, Ariege Bizanti
Electronic Theses and Dissertations
Astrocytes are among the most functionally diverse population of cells in the central nervous system (CNS) as they are essential to many important neurological functions including maintaining brain homeostasis, regulating the blood brain barrier, and preventing build-up of toxic substances within the brain, for example. Astrocyte importance to brain physiology and pathology has inspired a host of studies focused on understanding astrocyte behavior primarily from a biological and chemical perspective. However, a clear understanding of astrocyte dysfunction and their link to disease has been hampered by a lack of knowledge of astrocyte behavior from a biomechanical perspective. Furthermore, astrocytes (and …
Evaluating The Interaction Between The Human Melanocortin-2 Receptor And The Accessory Protein, Mrap1: Chimeric Receptor And Alanine Substitution Studies On Transmembrane Domain 4, Extracellular Loop 2, And Transmembrane Domain 5, Perry Victoria Davis
Electronic Theses and Dissertations
The melanocortin-2 receptor (MC2R) is the most complex due to its trafficking and ligand selectivity requirements for proper activation. The MC2R requires the melanocortin receptor accessory protein-1 (MRAP1) for proper trafficking and activation of the receptor by the melanocortin hormone, ACTH. MRAP1 is a single transmembrane-spanning domain protein that creates a homodimer with another MRAP1 protein. Furthermore, MRAP2 creates a heterodimer with the MC2R. Previous studies have shown that the MRAP1 protein contains an activation motif required for activation of MC2R and this activation motif located on the extracellular space side of the plasma membrane of the cell. The objective …

Olfaction, Memory, And Presence In Warfighters: Do The Scents Of War Matter?, Benson Munyan
Electronic Theses and Dissertations
Background: Exposure therapy (EXP) is a first-line intervention for combat-related PTSD. EXP works by repeatedly exposing the patient to the feared stimuli, situation, or physical sensations in the absence of actual danger until the stimuli no longer evoke maladaptive responses. Over the past decade, multiple technologies have been introduced to augment the EXP process by presenting multi-sensory cues (e.g., sights, smells, sounds) to increase patients' sense of presence. Exploratory research has only broadly examined the effect of odorants on the patient's sense of presence during simulated exposure tasks. This study hypothesized that those with autobiographical memories similar to the virtual …
Domestic Stalking, Violation Of Protective Orders, And Homicide In Chicago: The Influence Of Social Disorganization And Gender Inequality, Sarah Sacra
Electronic Theses and Dissertations
Domestic violence has been considered a serious issue for many decades. This problem manifests itself physically, sexually, and emotionally and can affect anyone. However, most of the domestic violence literature focuses specifically on physical intimate partner violence. Various theoretical frameworks have been utilized to explain the occurrence of domestic violence including social disorganization theory and gender inequality. These explanations are limited, however, with the former primarily extended to physical assault and the latter focusing on violence against women. This study is important as it extends our knowledge of how these two perspectives can be applied to domestic violence through the …

Electronic Theses and Dissertations
The disinfection of water for potabilization has proven to be one of the most significant public achievements of the 20th century. Although chemical disinfectants are successfully utilized to inactivate acute pathogenic organisms, they may react with natural organic matter (NOM) to produce potentially-harmful disinfection by-products (DBPs). As a result, the United States Environmental Protection Agency regulates DBPs such as total trihalomethanes (TTHMs) and haloacetic acids (HAAs). The research herein is focused on the formation, removal, and control of TTHMs and HAAs in a small public water system (PWS) in Polk County, Florida (County). Pilot-scale tests were implemented to determine the …
The Formation And Characterization Of Mesoscopic J- And H-Aggregates With Controlled Morphologies By The Co- And Templated Assembly Of Cyanine Dyes, Samuel Rhodes
Electronic Theses and Dissertations
The supramolecular aggregates of π-conjugated molecules have become an area of great interest to the scientific community in recent years for their promise in biosensors and optoelectronic devices. Among various supramolecular aggregates, J- and H-aggregates of πconjugated dye molecules are particularly interesting because of their unique optical and excitonic properties that are not given by individual molecules. H-aggregates are composed of dye molecules in a face-to-face stacking, giving rise to a blue-shifted absorption band compared with the monomer band and a strong emission quenching. In contrast, J-aggregates represent an edge-toedge stacking of dye molecules, showing a red-shifted absorption band with …
Human Factor Effects Of Simulating Battlefield Malodors In Field Training, William Pike
Human Factor Effects Of Simulating Battlefield Malodors In Field Training, William Pike
Electronic Theses and Dissertations
In order to explore how to better utilize simulated odors for live training, a study of 180 United States Military Academy at West Point cadets was undertaken to determine whether pre-exposure to a simulated malodor may result in an amelioration of performance issues, as well as improving performance of a complex task. Exposure to malodors has long been shown to increase stress and escape behavior, and reduce performance of complex tasks, in addition to degrading other human factor areas. However, desensitization to a particular odor through a process known as olfactory adaptation, could ameliorate these performance issues. In this study, …

Simultaneous Use Of Physiological Sensors For A Neuromarketing Task, Charles Descheneaux
Electronic Theses and Dissertations
Physiological measurements have become more popular in Psychological research over the past ten years. These advancements allowed different objective sensors to become another measurement tool in a scientific arsenal of collecting data. Traditionally, performance and after task subjective measures have been used for most studies in Psychological research. With the opportunity to use these subjective measures along with objective measures, more data can be collected during research and therefore potentially produce better quality conclusions. Eye Tracking (ET), functional near infrared (fNIR), transcranial Doppler ultrasound (TCD), electrocardiogram (EKG) and the electroencephalogram (EEG) have shown great promise in their ability to produce …
Simulating Human Pleura Performance In Medical Training Using Measured Tissue Mechanical Properties, Jack Norfleet
Simulating Human Pleura Performance In Medical Training Using Measured Tissue Mechanical Properties, Jack Norfleet
Electronic Theses and Dissertations
Medical simulations provide hands-on training at various levels of medical expertise. Yet these simulators fail to accurately mimic the look, feel and behavior of human tissue. Applying measured mechanical properties from human cadaver tissues promises to improve the fidelity of simulated tissue behaviors when subjected to medical procedures. Samples of human parietal pleura were tested under uniaxial tension to failure and measured characteristics were replicated in synthetic pleura. Context specific parameters were then collected and compared between human pleura and the new synthetics. These comparisons tested the hypothesis; H1 Gaps exist between synthetic and human pleura performance, H2: Human tissue …
Rewriting Patriarchal Norms In Academia: Invitational Rhetoric In A Crowdsourced Survey, Rachel Molko
Rewriting Patriarchal Norms In Academia: Invitational Rhetoric In A Crowdsourced Survey, Rachel Molko
Electronic Theses and Dissertations
This thesis seeks to understand the how texts are constructed to forward feminist communicative objectives through a case study of Dr. Karen Kelsky’s "A Crowdsourced Survey of Sexual Harassment in the Academy." In this research, sexual harassment is understood as an act of power, sexual in nature, enacted by faculty or staff (employed or contracted in different capacities) in their relations with other faculty or staff, who are often lower ranking. By adopting invitational rhetoric as a theoretical framework, this thesis examines the way Dr. Karen Kelsky's crowdsourced survey creates the space to articulate and elevate often suppressed personal testimony …
Rebuilt And Remade: The Florida Citrus Industry, 1909-1939, James Padgett
Rebuilt And Remade: The Florida Citrus Industry, 1909-1939, James Padgett
Electronic Theses and Dissertations
Prior to orange juice concentrate, Florida citrus was already an industrialized agricultural sector. This thesis explores the early-20th-century Florida citrus industry and demonstrates that contemporary farming practices were influential in advancing how citrus was produced, processed, worked, marketed, and regulated in early-20th-century Florida. Restarted after devastating freezes in 1894-1895, resolute Florida growers rebuilt their groves into marvels of large-scale citrus fruit production. Continuing a legacy in experimental crossbreeding, improved varieties of citrus were developed to lengthen the season and markets. Advocated by nurserymen and university educators, biological innovation helped the citrus thrive in the 1910s and 1920s from adverse weather …
Characterizing Biogeochemical Shifts In Two Salix Caroliniana Michx. Encroached Freshwater Subtropical Marshes, Janet Ho
Electronic Theses and Dissertations
Shrub encroachment is a common disturbance in wetlands, but little is known about how shrub encroachment impacts functions such as carbon (C) storage and nitrogen (N) cycling. The objective of this thesis was to identify differences in physiochemical properties (within soil, water and leaf tissue) and biogeochemical processes (soil respiration, enzyme activity, litter decomposition, and N cycling) in two subtropical freshwater marshes encroached by coastal plain willow (Salix caroliniana Michx.). Two study regions (Moccasin Island and Lake Apopka) were selected because of their location in the St. John's River watershed and their unique histories and hydroperiod, allowing for an investigation …

Effects Of Large-Scale Density Reduction On Brown Trout Growth And Movement In Spearfish Creek, South Dakota, Travis Rehm
Electronic Theses and Dissertations
Density-dependent growth is often observed in stream-dwelling Brown Trout Salmo trutta populations. In Spearfish Creek, South Dakota, biomass of adult Brown Trout (>200 mm) is about three times greater than that reported for similar Black Hills streams while mean length of adult fish is about 30% less. Here, we evaluate large-scale density reduction as a management tool for improving growth rate of stream-dwelling Brown Trout. We compared age-specific growth of wild Brown Trout in stream sections receiving 50% reductions in fish abundance. We also assessed the effect of fish density manipulation on Brown Trout movement patterns and home range …

Spore formers are observed as the common spoilage-causing microflora in milk and dairy products. Their spore-forming ability increases their survivability during heat treatment which leads to their presence in a final product. Spore-forming bacteria have ability to produce many types of spoilage-causing enzymes which are potential to influence quality and functionality of the final product. Many researchers have studied the ability of spore formers to induce a spoilage in various dairy products but as per our knowledge, their spoilage-causing activities are not described in a detail for cultured dairy products. In our first objective, we have studied the ability of …
Tripartite Interactions Of Legumes With Arbuscular Mycorrhizal Fungi And Rhizobial Bacteria: Insight Into Plant Growth, Seed Yield, And Resource Exchange, Arjun Kafle
Electronic Theses and Dissertations
Under natural conditions, legumes, such as alfalfa (Medicago) and soybean (Glycine max) are colonized with arbuscular mycorrhizal (AM) fungi and rhizobial bacteria forming tripartite interactions. Legumes are important crop species due to their high nutritional and economic values. Most of the previous literatures focused on experiments with an individual symbiont: either AM fungi or rhizobial bacteria, but not with both symbionts at the same time, thus our current understanding of resource exchange in tripartite interactions is limited. It has been reported that AM fungi primarily provide phosphate (P), nitrogen (N), and other nutritional and non-nutritional benefits while rhizobial bacteria solely …
