Shame And Guilt: The Good, The Bad, And The Ugly, Raika Sadeghein

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the past few decades, we have witnessed a growing body of literature on emotions in the consumer behavior domain. Emotions are defined as “mental states of readiness that arise from appraisals of events or one’s own thoughts” (Bagozzi, Gopinath, & Nyer, 1999, p. 184). Marketers have examined the role of emotions as stimuli, mediators, moderators, and responses to the environment. The broad topic of emotions includes subtopics such as impact of emotions on consumption, attitudes, and behavioral intentions, emotional responses to market stimuli, and the impact of emotions on cognition. However, although the study of emotions is pivotal to …

Elucidating A Common Mechanism Of Proteasome Impairment In Neurodegenerative Disease And Its Pharmacological Intervention, Tiffany Ann Thibaudeau

Graduate Theses, Dissertations, and Problem Reports (ETD)

Proteostasis is maintained by several systems in the cell including the ubiquitin-proteasome system (UPS), chaperones, chaperone-mediated autophagy, and macroautophagy. The UPS is the principle route for the degradation of intracellular misfolded, damaged, or unneeded cellular proteins and has a critical role essential every cell process, including: cell cycle progression, transcriptional regulation, genome integrity, apoptosis, immune responses, and neuronal plasticity. When the efficiency of protein degradation is perturbed, misfolded and damaged protein aggregates can accumulate to toxic levels and cause neuronal dysfunction, which may underlie many neurodegenerative diseases. It is widely appreciated that soluble oligomers of misfolded proteins (e.g. Aβ, Alzheimer’s; …

Many of the processes involved in this exhibition contain some form of collage. The use of these various collage techniques furthers the idea of complexity in perception and expression and the many layers of experience. I will explain how the creation …

The Structural Information Filtered Features Potential For Machine Learning Calculations Of Energies And Forces Of Atomic Systems., Jorge Arturo Hernandez Zeledon

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the last ten years, machine learning potentials have been successfully applied to the study of crystals, and molecules. However, more complex materials like clusters, macro-molecules, and glasses are out reach of current methods. The input of any machine learning system is a tensor of features (the most universal type are rank 1 tensors or vectors of features), the quality of any machine learning system is directly related to how well the feature space describes the original physical system. So far, the feature engineering process for machine learning potentials can not describe complex material. The current methods are highly inefficient …

Core Curriculum For Orchestra, Andrew Thomas Aycoth

Graduate Theses, Dissertations, and Problem Reports (ETD)

Core Curriculum draws inspiration from the idea of a sound collage that incorporates many specific pieces and techniques that I have encountered or studied during my time in music academia. Nearly everything is derived from something else, often being transformed or altered in some way. From my own private teaching of guitar lessons to analyses of 20th century art music, I tried to represent as much music as possible from these formative years. There are two main features that continue throughout the piece. The first is the repetitive rhythmic figure based on eighth notes that are out of phase, which …

Contemporary Music Notation For The Flute: A Unified Guide To Notational Symbols For Composers And Performers, Ms. Eftihia Victoria Arkoudis

Graduate Theses, Dissertations, and Problem Reports (ETD)

David Cope stated: “There are two basic approaches to the study of New Music Notation: codification and comprehension […] what really needs to be done is not to keep listing the diverse ways each composer symbolizes his music or create substantially new and negating systems of notation, but to concentrate on codifying one way for future composers to symbolize their music.”^[1]

In an attempt to limit the inconsistency and complexity characterizing contemporary notation idiomatic to the flute, this paper is the first to adopt Cope’s statement and ultimately apply it in relation to the notation of non-standard extended flute …

Morphological And Functional Evidence Of Sexual Dimorphism In The Retrochiasmatic Area Population Of Nk3r-Containing Neurons In Sheep, Justin A. Lopez

Graduate Theses, Dissertations, and Problem Reports (ETD)

Neurokinin B (NKB) and kisspeptin are critical for fertility and potent stimulators of gonadotropin-releasing hormone (GnRH) and luteinizing hormone (LH) secretion in sheep. We previously demonstrated that administration of NKB receptor (NK3R) agonist, senktide, within the retrochiasmatic area (RCh) resulted in surge-like release of LH and increased expression of kisspeptin neurons in the arcuate nucleus (ARC) of female lambs. We concluded that NKB-responsive neurons in the RCh stimulate GnRH secretion by inducing kisspeptin release from neurons in the ARC.

We have demonstrated morphological and functional evidence of sexual dimorphism in NKB-NK3R signaling in ovine RCh. RCh senktide administration resulted in …

Improving Solder Joints Formed In Microgravity By Use Of Magnetic Soldering Paste Additives, Aaron Dunkle

Graduate Theses, Dissertations, and Problem Reports (ETD)

With the expansion of the space industry, the need for the capability to repair electronics in space grows. Previous researchers have found that soldering in microgravity has yielded joints of poorer quality than those made on Earth, with increased interior porosity. WVU’s microgravity research team (MRT) constructed an experiment to solder onboard a microgravity aircraft to explore this problem and to test a possible solution. MRT’s experiment collected solder samples both in microgravity and a ground test, which were then cross-sectioned to allow the interior porosity of the joints to be studied. This determined that there was an increase in …

Adaptation Of The Streptococcal Collagen-Like Protein 1, Scl1, Of Group A Streptococcus To Recognize Fibronectin Type Iii Repeats, Dudley H. Mcnitt

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background: Group A Streptococcus (GAS) is responsible more than 700 million infections worldwide each year. Most of these infections start with initial colonization of the throat and skin, which is augmented by surface adhesins. The streptococcal collagen-like protein 1 (Scl1) is a major adhesin expressed by GAS that contains an N-terminal sequence-variable (V) domain, protruded away from the cell surface by the collagen domain. The Scl-V domain is comprised of three pairs of anti-parallel α-helices interconnected by surface-exposed loops. For attachment, GAS adhesins require a portal of entry, such as a wound or breach in the epithelium, to enter …

Breaking And Remaking The Mason-Dixon Line: Loyalty In Civil War America, 1850-1900, Charles R. Welsko

Graduate Theses, Dissertations, and Problem Reports (ETD)

Between 1850 and 1900, Americans redefined their interpretation of national identity and loyalty. In the Mid-Atlantic borderland of Maryland, Pennsylvania, Virginia, and West Virginia this change is most evident. With the presence of a free state and slave states in close proximity, white and black Americans of the region experienced the tumult of the Civil War Era first hand. While the boundary between freedom and slavery served as an antebellum battleground over slavery, during the war, the whole region bore witness to divisions between the Union and Confederacy as well as to define what loyalty and nation meant. By exploring …
