Scaling, Power-Law First Return Times, and Non-Ergodicity
This dissertation is a collection of papers on anomalous phenomena in physics, biology, and sociology. These phenomena are primarily analyzed in terms of their temporal and spatiotemporal statistical properties. The analysis is based on both numerical simulations and, in some cases, real-world physiological and sociological data. The primary methods of analysis are diffusion entropy analysis, power spectral analysis, multifractal analysis, and survival (or waiting-time) analysis.

Optimizing Value Co-Creation in Education Supply Chains: An Evaluation of Determinants and Resiliency in Service Systems
Services and service-based business are a major part of any economy. However, service-based supply chains require a greater level of interaction between provider and consumer than the traditional manufacturing or product-based supply chain. Therefore, they require optimization and resiliency models that acknowledge the constraints and goals unique to service-based industries. Value co-creation and service-dominant logistics (SDL) are relatively new to operations research. Existing literature in management science provides a framework for value co-creation but does not provide a model for optimizing value cocreation and resiliency in a complex or dynamic systems such as education supply chains (ESC). This dissertation addresses these knowledge gaps through 3 essays. The first essay establishes a method for optimizing investment in resiliency measures when utilizing parallel supply chains. The essay examines the intersection of value co-creation theory between higher education and service-dominant logistics (SDL) to understand the role of supply chain elements in value cocreation. The second essay provides a theoretical approach to incorporating resilience planning into the customer relationship management model. The final essay establishes a method for optimizing investment in resiliency measures when utilizing parallel service supply chains.

On the Descriptive Complexity and Ramsey Measure of Sets of Oracles Separating Common Complexity Classes
As soon as Bennett and Gill first demonstrated that, relative to a randomly chosen oracle, P is not equal to NP with probability 1, the random oracle hypothesis began piquing the interest of mathematicians and computer scientists. This was quickly disproven in several ways, most famously in 1992 with the result that IP equals PSPACE, in spite of the classes being shown unequal with probability 1. Here, we propose what could be considered strengthening of the random oracle hypothesis, using a stricter notion of what it means for a set to be 'large'. In particular, we suggest using largeness with respect to the Ramsey forcing notion. In this new context, we demonstrate that the set of oracles separating NP and coNP is 'not small', and obtain similar results for the separation of PSPACE from PH along with the separation of NP from BQP. In a related set of results, we demonstrate that these classes are all of the same descriptive complexity. Finally we demonstrate that this strengthening of the hypothesis turns it into a sufficient condition for unrelativized relationships, at least in the three cases considered here.

Factors Influencing Continued Usage of Telemedicine Applications
This study addresses the antecedents of individuals' disposition to use telemedicine applications, as well as the antecedents of their usage to provide insight into creating sustained usage over time. The theoretical framework of this research is Bhattacherjee's expectation-confirmation IS continuance model. By combining a series of key factors which may influence the initial and continued usage of telemedicine applications with key constructs of Bhattacherjee's IS continuance model, this study aims to provide a deeper understanding of barriers to telemedicine app usage and how to facilitate continued use of these apps. Online survey data was collected from college students who are telemedicine application users. A total of 313 responses were gathered, and data analysis was conducted using SmartPLS 3. This dissertation contributes by looking at the IS adoption and IS continuance research simultaneously to connect these two research streams as well as suggesting the usage context of some established IS theory being different with regard to healthcare applications.

The Informational Effects of Non-Deal Roadshows
Non-deal roadshows (NDR) are privately held one-on-one meetings between the buy-side of financial institutions and firm management. Using a novel dataset of these meetings, I examine the effects that NDR meetings have on the outcomes of two important corporate events: seasoned equity offerings (SEOs) and mergers and acquisitions (M&As). I also study the potential implications of the information content in NDRs on the behavior of stock returns following earnings announcements, which has been the subject of much academic work. I structure the dissertation in three essays. In the first essay, I examine the relationship between NDR activity and the underpricing of SEOs. I find that NDRs are associated with lower SEO underpricing. This association is stronger for firms with infrequent NDR activity, for smaller firms, and for firms with higher analysts' forecast errors. These findings suggest that NDRs reduce the level of asymmetric information between firms and investors, which results in a lower cost of raising equity. In Essay 2, I investigate whether the occurrence of NDR meetings affects post-earnings-announcement drift (PEAD). I find that PEAD declines after NDR activity when the most recent NDR meeting occurs within one month before the earnings announcement. This decline is most pronounced among …

The Emergence of All-State Vocal Jazz Ensembles in the United States from 1978 to 2022
Since the creation of the first all-state vocal jazz ensemble in 1978, similar ensembles have been established in roughly half of the United States. This paper contains historical summaries of the creation of all-state vocal jazz ensembles in nineteen of those states, primarily as recounted via interviews with those ensembles' founders. Each semi-structured interview was conducted over video conference or phone and lasted approximately one hour; resulting interview data was analyzed using qualitative methods. During the creation of each ensemble the respective founders needed to secure the support of a host organization, determine where and when to convene, and decide how to address auditions, sound reinforcement, rhythm sections, and funding. The diversity of solutions to these shared challenges reflects the diverse priorities of each founder as well as the unique conditions in which each all-state vocal jazz ensemble was established. However, several elements were common across these stories, including the influence of existing festivals and all-state ensembles, and tensions within the choral education community regarding the value of the vocal jazz idiom relative to traditional choirs, show choirs, and other vocal ensembles. In a few cases, established all-state vocal jazz ensembles were discontinued; these stories further illustrate the challenges such …

Processing-Structure-Property Correlation for Additively Manufactured Metastable High Entropy Alloy
In the present study both fusion based - laser powder bed fusion (LPBF), and solid state - additive friction stir deposition (AFSD) additive manufacturing processes were employed for the manufacturing of a metastable high entropy alloy (HEA), Fe40Mn20Co20Cr15Si5 (CS-HEA). A processing window was developed for the LPBF and AFSD processings of CS-HEA. In case of LPBF, formation of solidification related defects such as lack of fusion pores (for energy density ≤ 31.24 J/mm3) and keyhole pores (for energy density ≥ 75 J/mm3) were observed. Variation in processing conditions affected the microstructural evolution of the metastable CS-HEA; correlation between processing conditions and microstructure of the alloy is developed in the current study. The tendency to transform and twin near stress concentration sites provided excellent tensile and fatigue properties of the material despite the presence of defects in the material. Moreover, solid state nature of AFSD process avoids formation of solidification related defects. Defect free builds of CS-HEA using AFSD resulted in higher work hardening in the material. In summary, the multi-processing techniques used for CS-HEA in the present study showcase the capability of the AM process in tailoring the microstructure, i.e., grain size and phase fractions, both of which are extremely …

On the Utility of Surface Electromyography-Based Biofeedback on Rehabilitation from Total Knee Arthroplasty: A Clinical Trial
Knee osteoarthritis affects approximately 25 million adults. In severe cases, total knee arthroplasty (TKA) is the most common solution. TKA is effective at addressing pain and reducing continued degeneration of articular cartilage. However, effective physical therapy (PT) following TKA is vital for a full functional recovery. Despite the importance of PT, half of patients never achieve a full functional recovery. Decreases in proprioceptive feedback, severe atrophy, and pain inhibition all likely contribute to the variability in effectiveness. Surface electromyography-based biofeedback (sEMGBF) may allow clinicians to address some of these barriers by supplementing proprioceptive feedback and targeting small muscle contractions before eventually increasing the contraction requirement. Using a between group design, we compare the effectiveness of sEMGBF (7) to neuromuscular stimulation (NMES) (6), and a control group (6) in recovery following TKA. Effectiveness was evaluated across 4 metrics (quadriceps strength, range of motion, functional improvement, and quality of life) in a pre-test/post-test fashion. At the statistical level this study suggest that sEMGBF leads to greater improvements in quadriceps strength relative to the NMES and control group. Additionally, visual analysis suggests that sEMGBF may also lead to greater improvements in range of motion, and functional improvement relative to the NMES and control …

Occupancy Monitoring Using Low Resolution Thermal Imaging Sensors
Occupancy monitoring is an important research problem with a broad range of applications in security, surveillance, and resource management in smart building environments. As a result, it has immediate solutions to solving some of society's most pressing issues. For example, HVAC and lighting systems in the US consume approximately 45-50% of the total energy a building uses. Smart buildings can reduce wasted energy by incorporating networkable occupancy sensors to obtain real-time occupancy data for the facilities. Therefore, occupancy monitoring systems can enable significant cost savings and carbon reduction. In addition, workplaces have quickly adapted and implemented COVID-19 safety measures by preventing overcrowding using real-time information on people density. While there are many sensors, RGB cameras have proven to be the most accurate. However, cameras create privacy concerns. Hence, our research aims to design an efficient occupancy monitoring system with minimal privacy invasion. We conducted a systematic study on sensor characterization using various low-resolution infrared sensors and proposed a unified processing algorithms pipeline for occupancy estimation. This research also investigates low-resolution thermal imaging sensors with a chessboard reading pattern, focusing on algorithm design issues and proposing solutions when detecting moving objects. Our proposed approach achieves about 99% accuracy in occupancy estimation, …

Desertion and Defection in Roman Republican Warfare
Despite their many successes, Roman leaders continually struggled with indiscipline in their own ranks as they battled Rome's opponents. Desertion and defection were steps that soldiers often undertook to avoid their obligated service. Previous scholarship has largely overlooked this aspect of Roman warfare. This dissertation analyzes why Roman soldiers began turning to desertion and defection throughout the Republican period. Such cases were generally rare in early Rome, but the expanding responsibilities and hardships of warfare in the Middle Republic caused them to rise, as did the sizeable growth of the Roman community. The civil wars of the Late Republic saw especially high cases of such acts, as generals incentivized defections in their opponents ranks. Roman desertion was not unique, but a common occurrence in ancient warfare. This dissertation also addresses how Romans capitalized on desertion and defection in warfare. The Second Punic War offers an example of how Rome achieved victory by encouraging defection in its enemy's alliances. Romans also relied heavily on defectors as a source of intelligence and as a tool in siege warfare. The moral forces of commitment, discipline, dissatisfaction, and desertion were often as important as the tactics and technologies of the participants in Rome's wars.

Microstructure Evolution and Mechanical Response of Material by Friction Stir Processing and Modeling
In this study, we have investigated the relationship between the process-microstructure to predict and modify the material's properties. Understanding these relationships allows the identification and correction of processing deficiencies when the desired properties are not achieved, depending on the microstructure. Hence, the co-relation between process-microstructure-properties helped reduce the number of experiments, materials & tool costs and saved much time. In the case of high entropy alloys, friction stir welding (FSW) causes improved strength due to the formation of fine grain structure and phase transformation from f.c.c to h.c.p. The phase transformation is temperature sensitive and is studied with the help of differential scanning calorimetry (DSC) to calculate the enthalpy experimentally to obtain ΔGγ→ε. The second process discussed is heat treatment causing precipitation evolution. Fundamental investigations aided in understanding the influence of strengthening precipitates on mechanical properties due to the aging kinetics – solid solution and variable artificial aging temperature and time. Finally, in the third case, the effect of FSW parameters causes the thermal profile to be generated, which significantly influences the final microstructure and weld properties. Therefore, a computational model using COMSOL Multiphysics and TC-Prisma is developed to generate the thermal profile for different weld parameters to understand its …

Mastery in Colonial and Post-Colonial Brazil: José Maurício Nunes Garcia's (1767-1830) Use of Trombone in His "Missa De Santa Cecília" (1826)
Padre José Maurício Nunes Garcia (1767-1830) was perhaps the most prolific, revered, and successful composer in 18th and 19th century colonial and postcolonial Brazil. Padre José Maurício's favor with King Dom João VI, the Portuguese Royal Court, and a catalogue of hundreds of compositions, is validation of his success, yet there is comparatively little academic research and recognition in comparison to his European contemporaries. Padre José Maurício's employment of the trombone within his ambitious capstone, his Missa de Santa Cecília showcases his recognizable and original compositional language. The influence of two contemporaries of Padre José Maurício, Wolfgang Amadeus Mozart (1756-1791) and Gioachino Rossini (1792-1868), had an integral and clear influence on the Missa de Santa Cecília without resulting in rote imitation. Mozartian text emphasis, independent part writing, technical demand, and traditional use of the trombone for sacred or supernatural imagery were synthesized by Padre José Maurício swiftly and originally. Simultaneously, Rossinian orchestration, close scoring, limited range, subverted structural arrivals, and emulated percussive effects were personalized and employed by Padre José Maurício. His insular development and instantaneous adaptation of new orchestration and theatrical models yields trombone writing that is idiomatic, in alignment with sacred and symphonic tradition, and essential to the …

Response to Regulation of Technology: A Multi-Industry Perspective
Overall my dissertation work tries to capture a holistic view of the various complex interactions that occur in technology development, implementation, adoption and diffusion, in the context of three industries by examining issues that arise due to regulation of technology. Essay 1 focuses on the social media industry, which is in the early stage of the industrial life cycle, and is the foci of government attention for its ill effect on society. Results from the study (N= 647 employed adults in the US) supported hypotheses related to the antecedents and outcomes of platform utilization in the context of the three regulation dimensions. Essay 2 focuses on the automotive industry, which is in the growth stage of the industrial life cycle. Here the focus is on electric vehicles (EV) transitioning from the niches to the main market. Results from the longitudinal study (N = 429) support the moderating role of political activism on innovation capability of manufacturers and presence of ancillary services in the diffusion of different types of electric vehicles in the US market. Essay 3 focuses on the US healthcare industry, reflecting mature stage of industrial life cycle, yet also characterized with high cost and fragmentation of service. The …

Bifunctional Enamine‐Metal Lewis Acid Catalysis and α-Enaminones for Cyclization Reactions
The use of enamines continues to be an important tool in organic syntheses as both a catalyst and reactant. The addition of metal catalysts coupled with enamine catalysis has generated many reactions that normally would not occur separately. However, catalysts' incompatibility is an issue that we wish to solve allowing new chemistry to occur without hindrance. The use of enamines has continued to be a well-studied area of organic chemistry, but the field is ripe for different types of enamines to gain the spotlight. Enaminones are enamines with both nucleophilic and electrophilic properties. They allow reactions that are normally not possible with enamines to become obtainable. Chapter 1 is a brief introduction on enamines and the reason they gained so much attention. Then ends with enaminones and what makes them interesting reactants. Chapter 2 described a new synthesis for the tricyclic synthesis of chromanes using a novel bifunctional catalyst system of enamine-metal Lewis acid giving great yields (up to 87 %yield) and excellent stereoselectivity (up to 99 % ee). Chapter 3 covered new reactions for ring-open cyclopropane (up to 94% yield), tetrahydroquinolinones (up to 84% yield) and enantiospecific tetrahydroquinolinones (up to 84% yield and 97% ee) using α-enaminone and donor-acceptor …

Ultrafast Charge Transfer in Donor-Acceptor Push-Pull Constructs
Ultrafast charge and electron transfer, primary events in artificial photosynthesis, are key in solar energy harvesting. This dissertation provides insight into photo-induced charge and electron transfer in the donor and acceptor constructs built using a range of donor and acceptor entities, including transition metal dichalcogenides (TMDs, molybdenum disulfide (MoS2), and tungsten disulfide (WS2)), N-doped graphene, diketopyrrolopyrrol (DPP), boron-dipyrromethene (BODIPY), benzothiadiazole (BTD), free base and metal porphyrins, zinc phthalocyanine (ZnPc), phenothiazine (PTZ), triphenylamine (TPA), ferrocene (Fc), fullerene (C60), tetracyanobutadiene (TCBD), and dicyanoquinodimethane (DCNQ). The carefully built geometries and configurations of the donor and (D), acceptor (A), with a spacer in these constructs promote intramolecular charge transfer, and intervalence charge transfer to enhance charge and electron transfer efficiencies. Steady-state UV-visible absorption spectroscopy, fluorescence and phosphorescence spectroscopies, electrochemistry (cyclic voltammetry (CV) and differential pulse voltammetry (DPV)), spectroelectrochemistry (absorption spectroscopy under controlled potential electrolysis), transient absorption spectroscopy, and quantum mechanical calculations (density functional theory, DFT) are used to probe ground and the excited state events as well as excited state charge separation resulting in cation and anion species. The current findings are useful for the increased reliance on renewable energy resources, especially solar energy.

Self-Directed Leadership Development with Adaptive Learning 360-Feedback Platform
Leadership theories have evolved since their inception and leadership development should also evolve in response to the changing needs of their organizations. There is a gap in the literature on the functionality of the various 360-feedback platforms that are mentioned in literature which makes it difficult to understand what reporting functionality is available in existing systems. The goal of this study was to examine participants' views of a newly developed Adaptive Learning 360-feedback (AL360) treatment platform for leadership development with a focus on self-directed learning for improved accountability. Participants were asked to share their learning development experience in the areas of person, process, and context with suggestions for improvement and how did this development compare to any other leadership development that they had experienced in the past. The AL360 platform was built by applying the research findings of scholars in the areas of leadership, 360-feedback leadership development and educational technologies. The treatment was applied in a business setting for all levels of leadership development. The case study identified creation of leadership of self-awareness and accountability for development without significant intervention of an executive coach. The research findings also list improvement opportunities, limitations, and future considerations.

The Impact of Counter-Rumor Strategy and Source on Non-Professional Investors' Judgments over Social Media
Non-professional investors often rely on information obtained from social media to make investment decisions. Extant literature has not examined the most effective strategy for the target company to counter the rumors so that investors will be more willing to continue investing in the target firm. Drawing on source credibility theory and the moral intensity model, I propose that the most effective strategy would vary given different agents who are selected to counter the rumor. After conducting a 2 x 3 (counter-rumor source x counter-rumor strategy) experiment with 272 non-professional investors recruited from Amazon Mechanical Turk, my study shows that when an internal agent (e.g., the CEO) acts as a counter-rumor source, shareholders are more willing to invest in the company when the internal agent utilizes a denial strategy rather than a reassociation or a questioning strategy. In contrast, when an external agent (e.g., a famous food blogger) serves as the counter-rumor source, the external agent can also use a questioning strategy in addition to a denial strategy to motivate shareholders to be more willing to invest in the company; however, the external agent still needs to avoid from engaging a reassociation strategy. Moderated serial-mediation analysis shows that the persuasiveness of …

"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 …

Concerning Millennials: Exploring Generational Cohort Effects on Racial Linked Fate, Religion and Politics, and Support for American Civil Liberities
This research examines the political implications of the Millennial generation on American politics by exploring the interaction of generational cohort with race, social issues, and civil liberties. Relying on the 2016 Collaborative Multiracial Post-Election Survey and the 2018 General Social Survey, I examine (1) Millennial attitudes toward race and ethnicity by looking specifically at racial linked fate, (2) how Millennials interact with race and evangelical Christianity and how this interaction influences social policy preferences, and (3) how generational factors influence Millennial attitudes toward American civil liberties. I find that there are measurable effects of generational cohorts on the predicted value of Linked Fate for racial minority groups in the United States. My results suggest that Millennials are significantly more likely to have higher levels of linked fate for Latino and Asian Americans. However, I do not find sufficient evidence to suggest that African Americans' level of linked fate is affected either positively or negatively for Millennials. Second, for the investigation on social policy, the results suggest that those who sit at the intersection of the three groups- the Latino-Millennial evangelicals- hold policy preferences that contrast from those who are solely either Latino, Millennial, or evangelical. Latino-Millennial evangelicals are significantly more …

Three Essays on Phishing Attacks, Individual Susceptibility, and Detection Accuracy
Phishing is a social engineering attack to deceive and persuade people to divulge private information like usernames and passwords, account details (including bank account details), and social security numbers. Phishers typically utilize e-mail, chat, text messages, or social media. Despite the presence of automatic anti-phishing filters, phishing messages reach online users' inboxes. Understanding the influence of phishing techniques and individual differences on susceptibility and detection accuracy is an important step toward creating comprehensive behavioral and organizational anti-phishing awareness programs. This dissertation seeks to achieve a dual purpose in a series of three essays. Essay 1 seeks to explore the nature of phishing threats that including identifying attack intentions, and psychological and design techniques of phishing attacks. Essay 2 seeks to understand the relative influence of attack techniques and individual phishing experiential traits on people's phishing susceptibility. Essay 3 seeks to understand an individual's cognitive and affective differences that differentiate between an individual's phishing detection accuracy.

Three Essays on Size Premium Puzzle
Size premium puzzle, also known as the size effect, is one of the most studied anomalies in asset pricing literature. It refers to the observation that, on average, smaller firms have higher risk-adjusted returns than larger firms over a long period of time. While many studies have debated the existence of the size effect, the question of why it exists has become a subject of heated debate. Thus, this dissertation aims to examine if previously overlooked factors can, at least partially, explain the size effect. Essay 1 examines if merger and acquisition activity can explain a part of the size effect. I find that merger and acquisition activity explain a part of the size effect. The size effect is found to be stronger during merger waves but is not consistent across industries. Further, the size effect tends to be stronger when acquisition activity is concentrated among smaller firms. Essay 2 investigates if expectational errors explain the higher return of small firms. Several empirical studies show that stocks that investors underestimate yield higher returns. However, I do not find support for the underestimation explanation in explaining the higher returns of small firms. Instead, I find that investors are overly optimistic about …

Ethnic Parties: Their Emergence, Survival, and Impact
This dissertation examines the emergence of ethnic parties, their survival in the political system, and their impact on the governance practices. While scholars have long debated the impact of ethnic parties on state-building and democratization process, few works have empirically examined their behavior in the political system. Empirical research on ethnic parties is limited to single countries or regions -- Latin America, Eastern Europe, or a few countries including India. Firstly, this dissertation extends the research on ethnic parties to include another South Asian Country – Nepal. Secondly, research on ethnic parties has been hampered by the lack of cross-sectional data on ethnic parties. This dissertation employs new datasets on the electoral performance of ethnic parties, making use of the newly available resource. Employing both qualitative and quantitative techniques, this dissertation is built around three empirical chapters. Firstly, it argues that strategic interactions between major parties and ethnic groups, among others, determine why some ethnic groups successfully form their own parties and others do not. Secondly, it argues that the factors that are responsible for the emergence of ethnic parties are hardly sufficient for the survival of these parties in the long run and shows that ethnic parties' access to …

More Than Just a Test Score: Designing and Implementing a Community-Based Accountability System in One Texas School District
Since at least the 1960s, federal and state policymakers have debated how best to hold public schools accountable for producing graduates who are prepared to fully participate in our democratic society. Since that time, reform efforts have led to Texas' current test-based A-F accountability system. This qualitative case study explored how one Texas school district worked to design and implement an alternative accountability system. A community-based accountability system (CBAS) is created in collaboration with local stakeholders and uses locally developed goals and multiple achievement measures to report student and school performance. A zone of mediation theoretical framework was used to evaluate how the studied district assessed and addressed the community's norms, values, priorities, and goals for public schools. Data were drawn from an analysis of relevant documents, five individual district leader interviews, and a parent and/or community member focus group. These data were analyzed using a combination of a priori and in vivo coding. The six themes that emerged from this analysis were: (a) dissatisfaction with A-F accountability, (b) developing an alternative accountability, (c) collaboration with like-minded districts and leaders, (d) engagement with internal stakeholders; (e) engagement with external stakeholders, and (f) assessing community values and goals for public education. …
