All for the Greater Good: A Strategic, Tactical, and Operational Level Analysis of Supply Chain Goal and Incentive Alignment (open access)

All for the Greater Good: A Strategic, Tactical, and Operational Level Analysis of Supply Chain Goal and Incentive Alignment

Goal and incentive alignment are a means of establishing collaborative behavior in supply chains. Essay 1 examines goal and incentive alignment at the strategic level in the purchasing process. It employs survey research in conjunction with structural equation modelling to examine the source selection strategy as a means of aligning the goals of the offeror with those of the buyer. Essay 2 examines goal and incentive alignment at the tactical level. It uses discrete event simulation to explore how the pursuit of localized profit objectives affects the global profitability of a supply chain. Lastly, Essay 3 examines goal and incentive alignment at the operational level. By employing a hybrid simulation approach to model a complex product refurbishment process, this research demonstrates that evaluating subprocesses based solely on their throughput does not equate to greater cost savings for the company at the focal point of this case study. These essays contribute to the body of knowledge in several ways. To the best of the author's knowledge, Essay 1 demonstrates the first empirical linkage, in the realm of public procurement, between the fear of a bid protest and the appropriateness of the sourcing strategy. Similarly, Essay 2 represents the first adaptation of …

"All things at once":  A Retrospective Qualitative Examination of the Parental Racial Ethnic Socialization Practices Experienced by Multiracial/Multiethnic Individuals (open access)

"All things at once": A Retrospective Qualitative Examination of the Parental Racial Ethnic Socialization Practices Experienced by Multiracial/Multiethnic Individuals

The purpose of this phenomenological study was to explore how individuals from different multiracial/multiethnic groups experience and process the phenomenon of parental racial ethnic socialization (RES). Critical multiracial race theory, critical race theory, and bioecological systems theory offered a conceptual framework to how RES is often presented and processed. This study was guided by two research questions: (1) What are the experiences of RES among multiracial individuals? and (2) How do multiracial individuals process the parental racial ethnic socialization they were offered? Nine qualitative, one-on-one, semistructured interviews were conducted with individuals from three different multiracial/multiethnic groups. Results revealed that experiences of RES varied along with how participants processed RES. Three subthemes and one theme emerged related to the RES experiences of participants. For some participants lack of conversations were evident in their RES, which meant that conversations surrounding multiraciality and other racialized topics were not present. Other participants disclosed the subtheme of preparedness as part of their RES experience, while others mentioned the importance of environment to their RES experience. Additionally, the theme of changes over time arose, demonstrating how different life events can impact RES experiences. As for how multiracial/multiethnic individuals process RES experiences, the main theme of identity …

"Allegro de Concert," op. 46, by Frédéric Chopin: A Performance Guide

Frédéric Chopin produced a remarkable body of piano works. Even though most of his works are essential repertoire in piano literature, some of them remain less familiar. One such significant work is the Allegro de Concert in A major, op. 46, which was apparently intended to be the first movement of a third piano concerto. Despite the praise the work has received, it is rarely heard, and references to performance are lacking in the scholarly literature. Some reasons include the substantial technical challenges, such as risky skips, trills in double notes, thick harmonic textures, complex passagework, and the perpetual motion. This study provides a performance guide for the Allegro de Concert, looking at various perspectives of an informed musical performance. The historical backstory of the intended third concerto and a detailed form analysis demonstrate that the work has a combined form, incorporating elements of both concerto and sonata-allegro form. The chapter on performance presents the technical issues and a comparative analysis of various editions and arrangements of this work to inspire musical ideas and suggest appropriate solutions to the musical and technical difficulties.

Alloy Design, Processing and Deformation Behavior of Metastable High Entropy Alloys

This dissertation presents an assortment of research aimed at understanding the composition-dependence of deformation behavior and the response to thermomechanical processing, to enable efficient design and processing of low stacking fault energy (SFE) high entropy alloy (HEAs). The deformation behavior and SFE of four low SFE HEAs were predicted and experimentally verified using electron microscopy and in-situ neutron diffraction. A new approach of employing a minimization function to refine and improve the accuracy of a semi-empirically derived expression relating composition with SFE is demonstrated. Ultimately, by employing the minimization function, the average difference between experimental and predicted SFE was found to be 2.64 mJ m-2. Benchmarking with currently available approaches suggests that integrating minimization functions can substantially improve prediction accuracy and promote efficient HEA design with expansion of databases. Additionally, in-situ neutron diffraction was used to present the first in-situ measurement of the interspacing between stacking faults (SFs) which were correlated with work hardening behavior. Electron transparent specimens (< ~100 nm thick) were used in order to resolve nanoscale planar faults instead of the thicker sub-sized specimens (on the order of millimeters in thickness) which exhibit the classical stages III work hardening behavior characteristic of low SFE metals and alloys. …

Alterations in the Expression of Proteins Associated with Non-Alcoholic Fatty Liver Disease Observed in the Liver of the C57Bl/6 Wild-Type Male Mouse in Response to Exposure of Mixed Vehicle Emissions and/or High Fat Diet Consumption

Recent epidemiological studies have demonstrated a correlation between the manifestation of non-alcoholic fatty liver disease (NAFLD) and ambient air pollution levels, which is exacerbated by the presence of other risk factors, such as diabetes, dyslipidemia, obesity, and hypertension. We investigated the hypothesis that exposure to a mixture of gasoline and diesel engine emissions (MVE) coupled with the concurrent consumption of a high-fat (HF) diet promotes the development of a NAFLD phenotype within the liver. Three-month-old male C57Bl/6 mice were placed on either a low fat or HF diet and exposed via whole-body inhalation to either filtered (FA) air or MVE (30 µg PM/m3 gasoline engine emissions + 70 µg PM/m3 diesel engine emissions) 6 hr/day for 30 days. Histology revealed mild microvesicular steatosis and hepatocyte hypertrophy in response to MVE exposure alone, compared to FA controls, yielding a classification of "borderline NASH" under the criteria of the modified NAFLD active score (NAS) system. As anticipated, animals on a HF diet exhibited moderate steatosis; however, we also observed inflammatory infiltrates, hepatocyte hypertrophy, and increased lipid accumulation, with the combined effect of HF diet and MVE exposure. Immunofluorescence staining and RT-qPCR of the liver revealed the presence of lipid peroxidation, altered expression …

The Amalgamation of Western and Eastern Influences in Julius Schloss's "First Chinese Rhapsody" (open access)

The Amalgamation of Western and Eastern Influences in Julius Schloss's "First Chinese Rhapsody"

The dissertation seeks to rediscover Julius Schloss, a German Jewish composer victimized by the Nazis. Except for the promising start of his career in his early years, Schloss suffered a hard life as an exiled refugee. However, his unusual experiences inspired him to compose two Chinese Rhapsodies during his last years of exile in Shanghai, in which he synthesized Western composition techniques and Chinese folk materials, amalgamating influences from both Western and Eastern music cultures. Focusing on Schloss's First Chinese Rhapsody, the dissertation explores how Schloss links the new to the old, the West to the East, through an analysis of the way he employs Chinese folk song material and serial polyphonic voice-leading in his post-tonal musical language. Since the Rhapsody has both serial and polyphonic voice-leading aspects, both are analyzed, showing how they are integrated in the form.

Ambient Darkness and Consumer Behavior

Ambient lighting has emerged as a key atmospheric factor influencing how consumers process environmental cues and their behaviors. However, surprisingly little research has examined how people think and feel in the dark (lower than 15 lux). This is particularly relevant given that consumers routinely work, pay bills, relax, consume and make purchases in settings with little or no light. My dissertation addresses this gap by examining how consumers regulate their goals and process information when the light is off, and how that impacts their decision making in three substantive domains: risk-taking behavior, decision quality, and persuasion. In Essay 1, I propose darkness enables risk-taking behavior, and this effect happens through the calmness and relaxation induced in the dark. One caveat is that the decisions have to be made in a familiar setting. The effect was reflected in participants' decisions to invest in riskier yet lucrative stocks, to gamble with the riskier choice, to eat at a foreign restaurant, and to choose a supplement that has potential side effects in a field experiment and three lab experiments (pre-registered). In Essay 2, I propose that when the light is off, consumers are indeed induced to adopt an effortful processing mode. Across four …

An Analysis of Dependent Contingencies in a Triadic Interaction Using an Exchange Task to Understand Dynamic Concurrent Contingencies under Independent and Reciprocal Conditions

Although behavioral science, due to its emphasis on the use of single-subject research design, appears to focus solely on individual behaviors, behavioral scientists have a long history of lamenting the trajectory of humans, societies, and the discipline itself. Some scholars, for instance, called for our attention to expand our focus beyond individual behaviors to generate solutions for societal issues that we face. When we attempt to develop solutions for issues that require multi-level analysis, we must be cognizant of how institutional contingencies operate at the individual level. The current study analyzed triadic interactions using an exchange task in six triads. The result of this study showed that one common pattern of interactions among participants across triads was direct reciprocation between two participants. The implications of such findings, how they inform social behavior and metacontingency experiments, and future directions are discussed.

An Analysis of Federico Alvarez del Toro's Marimba Concerto "El Espiritu de la Tierra" (open access)

An Analysis of Federico Alvarez del Toro's Marimba Concerto "El Espiritu de la Tierra"

In this paper, I analyze the musical content in Federico Alvarez del Toro's marimba concerto El Espiritu de la Tierra. This dissertation represents my analysis of features I hear in the composition, and does not reflect the composer's original compositional process. Commissioned by the governor of Chiapas, the piece was composed in collaboration with internationally renowned marimba virtuoso Zeferino Nandayapa and premiered in 1984 with the Philharmonic Orchestra of Mexico City at Festival Cervantino in Guanajuato. The work has not been published and has been mentioned only briefly in scholarship. Particular attention in the analysis is given to indigenous and folk idioms from the southern region of Mexico combined with post-modern compositional techniques. My primary argument within the dissertation is that I believe the piece demonstrates a respect for tradition and heritage while concurrently utilizing non-traditional and contemporary compositional techniques. Analytically, I argue that two basic shapes are used throughout the piece, and I argue that the many cultural references within the piece solidify a preoccupation with the lineage of southern Mexico.

An Analysis of Information Technology (IT) Post-Adoption Behavior

The primary focus of this research is explicating the role of emotion in IT post-adoption behavior. Studied in the context of intelligent personal assistants (IPA), a class of conversational artificial intelligence (AI), the first study integrates elements from computer science, communications, and IS disciplines. The research identifies two constructs vital for speech-based technologies, natural language understanding, and feedback, and examines their role in use decisions. This work provides guidance to practice on how best to allocate R&D investments in conversational AI. The second essay examines the IT continuance through the theoretical lens of the expectation-confirmation model (ECM), incorportating cognitive and emotional satisfaction into the ECM framework. Empirical testing of the model suggests that it offers additional clarity on IT continuance phenomena and provides a significant improvement to the explanatory power of ECM in the context of an emerging technology. The third essay is one of the earliest efforts to conceptualize and test a theoretical model that considers emotional attachment in IT continuance behavior. This essay develops a novel model to investigate this phenomenon based on emotional attachment theory, and empirically validates the proposed model in the context of conversational artificial intelligence systems. While the existing theories of IT continuance focus …

An Analysis of Litigation against North Carolina Educators and School Districts under the North Carolina Tort Claims Act (open access)

An Analysis of Litigation against North Carolina Educators and School Districts under the North Carolina Tort Claims Act

This dissertation discussed the impact of the North Carolina Tort Claims Act and the history of governmental immunity that has protected school districts and school employees in North Carolina. The research question addressed was: how have North Carolina state courts interpreted the North Carolina Tort Claims Act in litigation against North Carolina school districts and their employees? The North Carolina Tort Claims Act provided citizens with a vehicle to sue local governmental agencies and their employees, such as school employees. The act also provided immunity for schools, especially for excessive damages in the case of negligence by an employee. The study examined how state courts have responded to different plaintiffs since the passage of the North Carolina Tort Claims Act in 1951. The decisions in the cases analyzed have been mostly favorable to schools, which has strengthened immunity for school employees. There were four legal aspects addressed by the courts after the passage of the North Carolina Tort Claims Act either most frequently or were unique to the case law of North Carolina. Those legal aspects were tests of school districts' governmental immunity; contributory negligence on the part of the plaintiff; the official capacity of school employees in lawsuits; and …

Analysis of Multipartite Bacterial Genomes Using Alignment-Free and Alignment-Based Pipelines

In this work, we have performed comparative evolutionary analysis, functional genomics analysis, and machine learning analysis to identify the molecular factors that discriminate between multipartite and unipartite bacteria, with the goal to decipher taxon-specific factors and those that are prevalent across the taxa underlying the these traits. We assessed the roles of evolutionary mechanisms, namely, horizontal gene transfer and gene gain, in driving the divergence of bacteria with single and multiple chromosomes. In addition, we performed functional genomic analysis to garner support for our findings from comparative evolutionary analysis. We found genes such as those encoding conserved hypothetical protein DR_A0179 and hypothetical protein DR_A0109 in Deinococcus radiodurans R1, and Putative phage phi-C31 gp36 major capsid-like protein and hypothetical protein RSP_3729 in Rhodobacter sphaeroides 2.4.1, which are located on accessory chromosomes in both bacteria and were not found in the inferred ancestral sequences, and on the primary chromosomes, as well as were not found in their closest relatives with single chromosome within the same clade. These genes emphasize the important potential roles of the secondary chromosomes in helping multipartite bacteria to adapt to specialized environments or conditions. In addition, we applied machine learning algorithms to predict multipartite genomes based on gene …

Analysis of the Accumulation, Toxic Effects, and Risk of Persistent Organic Pollutants in Pinnipeds (open access)

Analysis of the Accumulation, Toxic Effects, and Risk of Persistent Organic Pollutants in Pinnipeds

The present studies determine the accumulation of persistent organic pollutants (POPs) in three pinniped species, evaluate the relationship with relevant biomarkers of exposure, and calculate toxic effect thresholds. Stranded harp and hooded seals were found to be accumulating PBDEs at levels which could pose a based on threshold levels determined in this study. Northern fur seals are accumulating all three classes of POPs (PCBs, PBDEs, and OCPs) with significant relationships being seen with blubber percent lipid. Correlations between contaminant concentrations and expression levels of relevant biomarkers were seen potentially indicating an effect on multiple pathways. Overall risk can be hard to determine due to factors such as sex and age. Broad threshold response values and hazard quotients were calculated for toxic effect endpoints in pinnipeds. Overall these results suggest that certain populations of pinnipeds are at high risk of experiencing toxic effects due to POP exposure, but it is important to understand effects even at lower concentrations. The relationship between exposure, toxic effects, and other stressors, both environmental and physiological, can impact the overall fitness and survival of pinnipeds.

Analysis of the Cytochrome P450 and UDP-Glucuronosyltransferase Families and Vitamin D3- Supplementation in Anoxia Survival in Caenorhabditis elegans

Alteration in diet and knockdown of detoxification genes impacts the response of C. elegans to oxygen deprivation stress. I hypothesized that feeding worms a vitamin D3-supplementation diet would result in differential oxygen deprivation stress response. We used a combination of wet lab and transcriptomics approach to investigate the effect of a vitamin-D3 supplemented diet on the global gene expression changes and the anoxia response phenotype of C. elegans (Chapter 2). C. elegans genome consists of 143 detoxification genes (cyp and ugt). The presence of a significant number of genes in these detoxification families was a challenge with identifying and selecting specific cyp and ugt genes for detailed analysis. Our goal was to understand the evolution, phylogenetic, and expression of the detoxification enzymes CYPs and UGTs in C. elegans (Chapter 3). We undertook a phylogenetic and bioinformatics approach to analyze the C. elegans, detoxification family. Phylogenetic analysis provided insight into the association of the human and C. elegans xenobiotic/endobiotic detoxification system. Protein coding genes in C. elegans have been predicted to be human orthologs. The results of this work demonstrate the role of C. elegans in the identification and characterization of vitamin D3 induced alterations in gene expression profile and anoxia …

An Analysis of the Flypaper and Fungibility Effects of Intergovernmental Revenue on Municipal Operating and Capital Budgets

The flypaper effect states that grants-in-aid increases public spending more than a comparable increase in personal income. If aid increases spending, then there is the possibility that it displaces own-source revenue or a portion of the aid itself is used to meet other priorities of governments, fungibility. Different local government structures have the tendency to prioritize either the operating or capital budget. Empirical evidence shows that federal and state grants have different flypaper effect. While fungible state aid is allocated to the operating budget, that of federal goes to the capital budget. Council-manager and mayor-council form of governments do not allocate fungible intergovernmental aid differently between the capital and operating budgets.

An Analysis of the Representation of Queen Elizabeth I of England in the Operas by Rossini, Donizetti, and Thomas in the Context of Nineteenth-Century Vocal Style and Historical Influence (open access)

An Analysis of the Representation of Queen Elizabeth I of England in the Operas by Rossini, Donizetti, and Thomas in the Context of Nineteenth-Century Vocal Style and Historical Influence

The purpose of this research is to analyze representations of Queen Elizabeth I of England in nineteenth-century Franco-Italian opera, and the relationship of these representations to contemporaneous singing style and the historical background. The basis for this analysis is three arias: "Quant'é grato all'alma mia" from Elisabetta, regina d'Inghilterra (1815) by Gioachino Rossini (1792-1868), "Sì, vuol di Francia il rege...Ah! quando all'ara scorgemi...Ah! dal ciel discenda un raggio" from Maria Stuarda (1835) by Gaetano Donizetti (1797-1848), and "Malgré l'éclat qui m'environne" from Le songe d'une nuit d'été (1850) by Ambroise Thomas (1811-1896). This research is divided into two main sections: the historical background of Italy and France in the nineteenth century, especially in the contemporaneous vocal style and fashions of literature; and a discussion of the composers' musical and dramatic choices for Queen Elizabeth I in the three selected arias. Chapter 2 is a brief introduction to the early nineteenth-century Franco-Italian historical background, vocal style, and popular literature. Chapter 3 presents an analysis of the three arias. The last chapter summarizes the representations of Elizabeth I in nineteenth-century politics, literature, and vocal style.

An Analytical Study of Isang Yun's "Oboe and Oboe D'amore Concerto": The Intercultural Adaptation of Sigimsae for the Korean Piri with Modern Western Compositional Techniques for the Oboe

Isang Yun (1917-1995), one of the most important avant-garde German-Korean composers, is perhaps best known for his success at integrating Korean musical elements into traditional Western styles. His Concerto for Oboe, Oboe d'amore, and Orchestra incorporates many traditional Korean elements, and uses techniques such as Hauptton, Hauptklang, and Umspielung to blend these elements into a Western musical style. This study explores the elements of traditional Korean music and instruments present in Yun's score, examines his compositional techniques, and makes practical performance suggestions that allow performers to properly convey his intentions. This dissertation includes six chapters. The first chapter discusses the purpose and importance of the study. The second chapter reviews Isang Yun's biography and works, based on a published interview with Yun and a biography written by his wife of many years. The third chapter introduces the characteristics of traditional Korean woodwind instruments relevant to the work. The fourth chapter examines Yun's compositional techniques of Hauptton, Hauptklang, and Umspielung in the work and their relationship with the main-tone and Sigimsae techniques. The fifth chapter introduces and explores different types of Sigimsae in the work, with suggestions for quarter-tone performance techniques. The sixth and last chapter is a conclusion.

An Analytical Study of the Suite for Violin and Piano (1935), Op. 6, by Benjamin Britten (1913-1976) (open access)

An Analytical Study of the Suite for Violin and Piano (1935), Op. 6, by Benjamin Britten (1913-1976)

The Suite for Violin and Piano, Op. 6 is one of the least-known compositions by Benjamin Britten. It has been considered unfavorably by critics and scholars due to its puzzling mixture of tonal and post-tonal elements. However, this dissertation argues that the suite is composed with a clear tonal framework, and its unique mixed tonal-post-tonal language justifies an in-depth analysis. This analytical study utilizes a linear progression technique - the voice leading produced by passing tones and neighbor notes around focal pitches - to identify tonal areas of the suite.

An Analytical Survey of Hendrik Hofmeyr's Compositions for Solo Saxophone (open access)

An Analytical Survey of Hendrik Hofmeyr's Compositions for Solo Saxophone

Hendrik Hofmeyr is considered one of the most important and influential living composers in South Africa. His music for solo saxophone is not well-known in the classical saxophone repertoire. His four works for solo saxophone (Concerto per saxofono contralto e orchestra, Concerto per saxofono baritono e orchestra, Partita canonica, and Necromancer) are substantial and terrific repertoire for the instrument. This study is intended to inform a saxophone performer's understanding of these compositions through analysis of form, melodic, and harmonic content relevant to performance; and, demonstrate through example the conclusions determined by the analysis about apparent compositional techniques in the music.

Analyzing the Joint Effects of Network and Community Attributes on Network Performance: Evidence from Local Continuum of Care Homeless Service Networks

This dissertation examines the factors and combinations of factors that affect the performance of continuum of care homeless service networks, applying the configurational approach of contingency theory to data sets drawn from federal sources. The study accepts the two key assumptions from the theory: (1) that there are multiple paths to high performance and (2) key conditions have a joint influence on network performance. The data analysis in this study has two parts. The first employs OLS regression to examine the causal relationship between independent variables and the performance of permanent supportive housing (PSH) programs. This study also applies fuzzy set qualitative comparative analysis (fsQCA) to identify multiple combinations of factors that influence the performance of PSH programs. The results identify key factors and multiple combinations of factors that lead to high and low network performance. Federal CoC funding emerges as a core condition for high and low performance, but all relevant conditions can be critical factors depending on how they interact with other relevant conditions. This analysis helps expand the utility of existing contingency theory by using it to explain the dynamic interactions between factors in the context of public service networks. Ultimately, this dissertation confirms that fsQCA can …

Analyzing the Principal Perspective to Lead the Implementation of Learning Technologies in Public Schools: A Multi-Strategy Study (open access)

Analyzing the Principal Perspective to Lead the Implementation of Learning Technologies in Public Schools: A Multi-Strategy Study

As technologies for learning become increasingly available in K-12 schools, the role and responsibilities of campus principals continue to evolve. Incorporating technologies in schools requires shifts in practices, the development of new skills, and in some cases, changes in the mindset of stakeholders. Schools should be capable of absorbing the knowledge and creating the systemic structures required for the implementation ICTs. The purpose of this study was to research the principals' perspective to lead the implementation of ICTs for learning in public schools. As campus leaders, principals are increasingly required to support the utilization of ICTs for classroom instruction. It is of particular importance, therefore, to study and explore the needs school principals identify to lead the implementation of technologies for learning. More specifically, the goal was to gather relevant data to analyze topics that campus principals believe positively and negatively influence the implementation of ICTs in schools.

Annihilators of Irreducible Representations of the Lie Superalgebra of Contact Vector Fields on the Superline (open access)

Annihilators of Irreducible Representations of the Lie Superalgebra of Contact Vector Fields on the Superline

The superline has one even and one odd coordinate. We consider the Lie superalgebra of contact vector fields on the superline. Its tensor density modules are a one-parameter family of deformations of the natural action on the ring of polynomials on the superline. They are parameterized by a complex number, and they are irreducible when this parameter is not zero. In this dissertation, we describe the annihilating ideals of these representations in the universal enveloping algebra of this Lie superalgebra by providing their generators. We also describe the intersection of all such ideals: the annihilator of the direct sum of the tensor density modules. The annihilating ideal of an irreducible non-zero left module is called a primitive ideal, and the space of all such ideals in the universal enveloping algebra is its primitive spectrum. The primitive spectrum is endowed with the Jacobson topology, which induces a topology on the annihilators of the tensor density modules. We conclude our discussion with a description of the annihilators as a topological space.

Antecedents to Reliance on Artificial Intelligence and Predictive Modeling

Artificial intelligence (AI) and predictive modeling are tools used to diagnose a disease, determine how much a home is worth, estimate insurance risks, and detect fraud. AI and predictive modeling are so ubiquitous that they can be why one gets spam and why spam is automatically deleted. Information science integrates interdisciplinary elements of data-driven, behavioral, design, interpretive, and analytical research methodologies to design and understand interactions between digital media, information systems, and humans. This research focuses on the interaction between humans, AI, and predictive models. This research proposes a theoretical framework and a conceptual research model to understand the antecedents to reliance on AI and predictive modeling. The dissertation follows a traditional format that includes three studies.

An Anthology of Tenor Arias from Korean Operas

The first Western opera to be performed in Korea was Verdi's La Traviata on January 16, 1948, by the Joseon Opera Company. The first Korean opera, Chunhyangjeon by Jae Myung Hyun, premiered at the Korean National Theater in May 1950, just before the outbreak of the Korean War. Daejeon.go.kr reports that since that year approximately 200 Korean operas have been produced in Korea. Nevertheless, there have been consistent efforts to create and introduce Korean operas to the public. Most of them ended up being "one-off" performances with a single production. Most research on Korean opera has focused on its history, the challenges of producing new operas, or an analysis of selected Korean operas. This study equips singers with the following: pertinent historical background with the libretto, a synopsis, research regarding the composer and librettist, a character analysis, vocal and textual analysis of the selected opera arias, instruction regarding the Korean language, IPA, and a word-by-word translation of the text. I also make recommendations for tenor arias from Korean operas for singers with specific voice types.
