The Effect Of Phonetic Training On The Perception And The Production Of L1-Related Difficult Sounds In Esl, Moonjung Jang

Graduate Theses, Dissertations, and Problem Reports (ETD)

A considerable amount of research has been conducted on the influence of first languages’ phonological features in pronunciation of a second language. While it has been accepted that pronunciation is one of the most significant aspects in the acquisition of a second language, many studies have not considered whether explicit phonetic training in pronunciation would help English as Second language Learners to improve their pronunciation on particular English sounds that can be confused due to L1 influence. The present study will explore whether Korean ESL learners are able to perceive the particular pairs of the different phonetic sounds (i.e., /p/-/f/, …

Graduate Theses, Dissertations, and Problem Reports (ETD)

Online Model Predictive Control of a Nonisothermal and Nonisobaric Membrane Reactor for Water-Gas Shift Reaction Applications Jacob M. Douglas Modern hydrogen production units are tasked with producing the most hydrogen possible while dealing with flow variations caused by changing power demands. Classical methods for hydrogen production employing the water-gas shift reaction are governed by equilibrium limitations that take effect at high temperatures and high concentrations of H2 (Georgis, et al., 2014). The implementation of a membrane reactor with temperature control enables the hydrogen concentration and temperature to reach an equilibrium at a higher concentration of H2. Another challenge that is …

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 …

The /H/ Phenomenon: Overgeneralised Or Confused? The Nigerian Yoruba-English Speakers As A Case Study, Oluwabukola Omolara Bamidele

Graduate Theses, Dissertations, and Problem Reports (ETD)

In this thesis, I examined why the Yoruba speakers of the English language have difficulty in pronouncing word-initial glottal fricative in English. /h/ dropping and /h/ insertion is not expected as the Yoruba language supposedly have the glottal fricative in its sound inventory. I gave a brief introduction to Yoruba phonetics, a brief history about the contact between English and Yoruba language, and what other researchers have written about the /h/ dropping and insertion phenomenon.

The research question was why the Yoruba-English speakers delete and insert the glottal fricative at the word-initial position. I started by investigating the nature of …

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 …

Graduate Theses, Dissertations, and Problem Reports (ETD)

My research focuses on investigating the impact of moisture-induced and oligomer-induced viscosity changes on OH-initiated oxidation of semi-solid aerosols,and the role of gas-liquid interfaces in regulating aqueous aerosol chemistry. Saccharides, which are a major constituent of aqueous atmospheric aerosols, are chosen as model molecules to form highly oxygenated organic aerosols. The experiments are performed using an atmospheric pressure flow-tube reactor with both online VUV-AMS (Vacuum-Ultraviolet Aerosol Mass Spectrometer) and offline GC-MS analysis techniques. The decay rates of saccharide are determined by measuring the loss signal of saccharide in the particle phase as a function of OH exposure (time-integrated total concentration …

Object-Based Supervised Machine Learning Regional-Scale Land-Cover Classification Using High Resolution Remotely Sensed Data, Christopher A. Ramezan

Graduate Theses, Dissertations, and Problem Reports (ETD)

High spatial resolution (HR) (1m – 5m) remotely sensed data in conjunction with supervised machine learning classification are commonly used to construct land-cover classifications. Despite the increasing availability of HR data, most studies investigating HR remotely sensed data and associated classification methods employ relatively small study areas. This work therefore drew on a 2,609 km2, regional-scale study in northeastern West Virginia, USA, to investigates a number of core aspects of HR land-cover supervised classification using machine learning. Issues explored include training sample selection, cross-validation parameter tuning, the choice of machine learning algorithm, training sample set size, and feature selection. A …

Feed hygienics are of increasing importance in providing safe feed to animals, and ultimately safe food for consumers. Salmonella has been identified as a major microbial hazard in animal feed that has been linked to animal and human illness. In chapter 2, the effects of standard pelleting and more thermally aggressive techniques were utilized to determine pathogen mitigation potential. Use of antibiotics has decreased in recent years …

Los Ritmos Latinoamericanos Como Estrategia De Resistencia En La Ópera La Ruta De Su Evasión (2017) De Abya Yala Y Carlos Castro, Pamela Zamora Quesada

Graduate Theses, Dissertations, and Problem Reports (ETD)

In this Master’s thesis I examine the most recent Costa Rican opera The Path of Avoidance (2017), produced by the Cultural Association for Performing Arts Abya Yala, directed by Roxana Ávila and composed by Carlos Castro, based on the homonymous novel of Yolanda Oreamuno (1948).Through a semiotic analysis, I will discuss how the innovative manner of incorporating Latin American rhythms such as salsa, bolero, vals criollo, bossa nova and tango is a musical strategy which promotes a problematization of the gender dominant discourse and patriarchal context. Simultaneously, these rhythms offer a way of resistance on the direct or psychological violence …

A Compendium Of Opera In Spain And Latin America, Michelle S. Smith

Graduate Theses, Dissertations, and Problem Reports (ETD)

Spain and Latin America have a rich operatic tradition, however this opulent body of operatic work is mostly overlooked or ignored in mainstream histories of opera. This document focuses on opera in Spain and the Spanish-speaking countries of Latin America. Opera was both composed and performed in Spain and Latin America, and both regions demonstrate the development of national opera traditions. Spanish drama was closely linked to the beginnings of national opera, and Italian influence is evident in opera compositions from both regions. The output of national operas varies by country, with Spain, Mexico, and Argentina claiming the majority of …

Legitimacy, Procedural Justice, And Neighborhood Dynamics: Thoughts On Police Reform, Robert Lyle Nicewarner

Graduate Theses, Dissertations, and Problem Reports (ETD)

Currently, there is much debate about how to alleviate tensions between communities and police. These tensions do not illustrate the full scope of the problem, but show us symptoms of a larger, more structural issue. Many scholars point to procedural justice tactics as a way to increase the legitimacy of the police; thus, creating a safer environment where citizens do not fear the police but respect, obey, and defer to them. However, not every neighborhood is the same and not every neighborhood needs the same kind of policing style. Drawing on theories of collective efficacy and social cognition I propose …

Framing Effects On Fear Of Terrorism And Willingness To Sacrifice Civil Liberties, Ellory Ruth Dabbs

Graduate Theses, Dissertations, and Problem Reports (ETD)

The purpose of this research was to determine whether differences in the way the media frames an act of violence leads to different reactions by consumers. In particular, it was hypothesized that the ideology and race of the perpetrator would lead to differences in perceptions of whether or not the attack was terrorism. A vignette-style experiment was performed using respondents recruited via MTurk. Four versions of the vignette were evenly distributed to 441 respondents, changing whether the frame contained a photo, the ideology, and the name of the perpetrator. Using measures of fear from this data it was then investigated …

Comparing Measures Of Physical Activity Intensity, Duration, And Frequency Using Receiver Operator Characteristic Curve Analyses, Abigail M. Nehrkorn-Bailey

Graduate Theses, Dissertations, and Problem Reports (ETD)

The United States Department of Health and Human Services (HHS) recommends adults to engage in weekly moderate- or vigorous-intensity physical activity based on its association with various physical and psychological health benefits (HHS, 2008; Schoenborn, Adams, & Peregoy, 2013). These physical activity recommendations contain important information for three physical activity components: intensity, frequency, and duration. The current physical activity literature contains gaps, with a lack of specificity for which components are being studied. Although some of the literature does describe the physical activity components, there are many discrepancies in the level of agreement across subjective and objective measures, along with …

Sediment Provenance Study Of The Lower Hamilton Group: An Analysis Of The Organic-Rich Facies And Its Depositional History, Luke Patrick Fritz

Graduate Theses, Dissertations, and Problem Reports (ETD)

Currently, insufficient geological models exist to explain the variability and distribution of TOC in the Marcellus Shale, within the Hamilton Group. TOC is one of the several limiting factors for natural gas production within the Marcellus Shale basin. One possible explanation for the low TOC regions is that detrital dilution was variable across the basin, with different sediment sources contributing detritus to low TOC areas, compared to surrounding regions with higher TOC. This hypothesis is tested by analyzing the source composition of inorganic detritus, using elemental and mineralogical proxies, with two cores in the Hamilton Group. The Armstrong #1 core …

Compound-Specific Isotope Analysis Of Amino Acids In Biological Tissues: Applications In Forensic Entomology, Food Authentication And Soft-Biometrics In Humans, Mayara Patricia Viana De Matos

Graduate Theses, Dissertations, and Problem Reports (ETD)

In this work we demonstrate the power of compound-specific isotope analysis (CSIA) to analyze proteinaceous biological materials in three distinct forensic applications, including: 1) linking necrophagous blow flies in different life stages to their primary carrion diet; 2) identifying the harvesting area of oysters for food authentication purposes; and 3) the ability to predict biometric traits about humans from their hair.

In the first application, we measured the amino-acid-level fractionation that occurs at each major life stage of Calliphora vicina (Robineau-Desvoidy) (Diptera: Calliphoridae) blow flies. Adult blow flies oviposited on raw pork muscle, beef muscle, or chicken liver. Larvae, pupae …

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: Interest in college food insecurity has increased in previous years, however, little research focuses on the Appalachian and Southeastern regions of the United States resulting in limited understanding of food insecurity’s impact on college students in these regions. Additionally, resources to help food insecure students are often sparse with universities lacking evidence-based programming to implement for student benefit.

Aims: This dissertation aims to (1) investigate the correlates and behavioral consequences of food insecurity on college students at an Appalachian university, (2) expand college food insecurity research to a regional investigation in the Appalachian and Southeastern regions, and (3) develop …

Bridging The Gap: Utilizing Socratic Inquiry Facilitation In Cross-Cultural Communication And Conflict Exploration, Mikaela G. Zimmerman

Graduate Theses, Dissertations, and Problem Reports (ETD)

The objective of this research is to explore the possibilities for improving governmental relations (local, national, and international) using microcosms of cross-cultural dialogues facilitated with Socratic Inquiry methodology and their potential to project situational similarities into more formal political conversation. Using twenty-five recorded dialogues from The Pennsylvania State University’s Center for Public Diplomacy (World in Conversation), I have broadly observed the role of Socratic Inquiry facilitation in cross-cultural dialogues whose content varies across a span of contentious social topics. By generally accounting for a range of relevant social factors such as gender, body language, conversational tools, and proxies for empathy, …
