Two Million "Butterflies" Searching For Home: Identity And Images Of Korean Chinese In Ho Yon-Sun's Yanbian Narratives, Xiang Jin

Theses and Dissertations

This thesis examines the representation of Korean Chinese searching for home in relation to Korean diasporic identity. Home as a sense of identity is both personal and collective. It is also a reflection of one’s psyche and emotion. For Korean Chinese, searching for a place to call home in between their host-homeland China and original homeland Korea involves many aspects of meaning, the home of an individual, of a family, and of a community. Therefore, the third cultural region Yanbian, the Korean Chinese Autonomous Prefecture of China, and Yanbian narratives become the central issue of this thesis. I first offer …

Regulation Of Stress Response And Innate Immunity By DsRna-Binding Proteins Pact And Trbp, Lauren S. Vaughn

Theses and Dissertations

An integral aspect of innate immune response to viral infections is the ability to detect non-self molecules to initiate antiviral signaling via pattern recognition receptors (PRRs). One subset of these receptors are cytoplasmic receptors that contain double stranded (dsRNA) binding domains, which allow them to identify non-self dsRNA produced during a viral infection and mount a protective cellular response. PKR is a dsRNA-activated eIF2α kinase that is a key regulator of cellular antiviral and stress response pathways. Activation of PKR’s catalytic activity requires binding to one of its activators, viral dsRNAs or the cellular protein PACT (PKR activator). Although PACT …

Confluence Of Density Currents Over An Erodible Bed, Hassan Ismail

Theses and Dissertations

Results from laboratory experiments on conservative density current confluence are reported. Hydraulic characteristics and morphodynamic consequences of the confluence of two continuous release density currents in a horizontal, 45 degree asymmetrical junction are examined and compared to those of terrestrial river junctions. It was observed that density current confluence is markedly different than those in river junctions primarily due to the ease of the dense fluid to convect into the ambient fluid in the junction zone. Upward convection in the junction resulted in low horizontal velocity and shear stresses on the bed of the junction zone, followed by re-plunging to …

Preparation And Characterization Of Pt-Ru Bimetallic Catalysts Using Electroless Deposition Methods And Mechanistic Study Of Re And Cs Promoters For Ag-Based, High Selectivity Ethylene Oxide Catalysts, Weijian Diao

Theses and Dissertations

Pt-Ru bimetallic catalysts are widely used for direct methanol fuel cells, biomass upgrading and hydrocarbon refining and offer unique properties compared to Pt or Ru monometallic catalysts due to ensemble effects, electronic effects, and/or bifunctional effects. To achieve better performance, strong metal-metal interactions and true bimetallic surface are needed. Electroless deposition (ED) methods are used in our laboratory to synthesize such bimetallic catalysts. In this study, two series of Ru@Pt/C (Pt deposited on Ru surfaces) and Pt@Ru/C (Ru deposited on Pt surfaces) catalysts have been synthesized. Characterization data from temperature programmed reduction (TPR), selective chemisorption, X-ray photoelectron spectroscopy (XPS), and …

Metabotropic Receptor Modulation Of Kainate Receptors In The Hippocampus, C'Iana Patrice Cooper

Theses and Dissertations

Kainate receptors (KARs) are glutamate-gated ion channels that mediate synaptic transmission, modulate transmitter release, and mediate excitation in the brain. Potentiation in their function predisposes the hippocampus to hyperexcitability and seizures. These receptors are widely expressed throughout the central nervous system as tetramers composed of various combinations of GluK1-5 subunits. In the hippocampus (a brain region commonly associated with seizure initiation), GluK2-, GluK4-, and GluK5-containing receptors are highly expressed in the CA3 pyramidal cell layer, whereas GluK1 is barely detectable. The lack of pharmacological tools hinders identifying the functional contribution of each kainate receptor subtype in normal CA3 synaptic transmission. …

Optimized Spectral Processing Of Infrared Diffuse Reflection Spectra For The Detection Of Blood On Fabric, Stephanie Ann Dejong

Theses and Dissertations

The detection of bodily fluids such as blood on interfering backgrounds is important to the forensic community. Luminol, which participates in a chemiluminescent reaction with the heme groups of blood, is one of the most commonly used presumptive tests. Luminol has a few drawbacks, including the requirement of use in a dark environment and potential to degrade the amount of recoverable DNA in blood stains. A potential complementary method is infrared (IR) spectroscopy. These two methods are compared in this work. Infrared diffuse reflection (DR) spectroscopy works well to measure the IR spectrum of samples that are highly absorbing or …

General Strain Theory And Bullying Victimization: Do Parental Support And Control Alleviate The Negative Effects Of Bullying, Jonathon Thompson

Impact Of Formulation And Processing Parameters On Mechanical Properties Of Magadiite/Elastomer Composites, Yating Mao

Theses and Dissertations

This work seeks a better understanding of mechanical reinforcement and energy dissipation in elastomer composites containing the layered silicate magadiite (MGD, Na2Si14O29·nH2O). We characterized the elastomer’s accessibility into MGD interlayer spaces and studied the factors that influence the composite mechanical properties. We also compare the mechanical reinforcement of MGD with montmorillonite (MMT, a layered aluminosilicate clay mineral), which is widely used as filler in other kinds of nanocomposites. The study explores the grafting chemistry, vulcanization, and reinforcement mechanism in MGD/elastomer composites, which may help us to formulate the platelet/elastomer composites with superior mechanical properties and performance in the future. We …

Situationism And The Promise Of Virtue Ethics, Richard Barclay Holmes

Theses and Dissertations

In this dissertation, I argue that it is possible to develop an empirically adequate form of virtue ethics even if one grants that situationism is true. I define situationism as a skeptical thesis about globalism, or the thesis that temporally stable and trans-situationally consistent character and personality traits are widely instantiated. Situationists such as John Doris and Gilbert Harman argue that globalism is an empirically inadequate thesis. While I accept Doris and Harman’s situationist thesis, they also make a further argument which is the subject of this dissertation. They argue that since globalism is empirically inadequate and Aristotelian virtue ethics …

Dielectric Characteristics Of Microstructural Changes And Property Evolution In Engineered Materials, Jallisa Janet Clifford

Theses and Dissertations

Heterogeneous materials are increasingly used in a wide range of applications such as aerospace, civil infrastructure, fuel cells and many others. The ability to take properties from two or more materials to create a material with properties engineered to specific needs is always very attractive. Hence engineered materials are evolving into more complex formulations or heterogeneities in multiple disciplines. Design of microstructure at multiple scales controls the global functional properties of these materials and their structures. However, local microstructural changes do not directly cause a proportional change to the global properties (such as strength and stiffness). Instead, local changes follow …

Survival: A Teach For America Memoir, Christopher Neal Schumerth

Theses and Dissertations

“I grab Franklin and pull him upright, standing in between him and the smaller student. I spread my arms in each direction. That second of new life gives the smaller student renewed vigor. His fists shoot around and even into me. Franklin, whose punches actually hurt, gladly obliges in kind. Suddenly, I am the main, albeit incidental, object of both children’s rage. A sharp, stabbing pencil glances off my wrist, drawing blood. I look at the two cafeteria workers, dressed in white and protected by a shield of glass and the food they are distributing. They look the other way.” …

Global Methylation Of Dna Among Spartina Alterniflora Clones Differing In Age At North Inlet, Sc, Trenton Agrelius

Theses and Dissertations

“Brown marsh” or “sudden marsh dieback” refers to the rapid death of patches varying in size of Spartina alterniflora. In 2000 following a 100-year record drought, approximately 8,000 hectares of S. alterniflora died along the Louisiana coast, which prompted Louisiana Governor Foster to declare a state of emergency. Other cases have been documented at North Inlet, SC as well as various other marshes along the southeastern United States. Currently, there is much dispute regarding the cause of “sudden marsh dieback” but environmental stress is one of the acknowledged constants across sites. We hypothesized an alternative mechanism in which methylation of …
