Preferred Qualifications of Collegiate Athletic Directors: Opinions of Presidents and Athletic Directors

Description: This study explored the preparation methods, qualifications and criteria that both university and athletic directors deemed necessary when searching for athletic directors. Participants completed a survey via Qualtrics online software. Two different populations were sampled for this study: 651 university presidents and 651 athletic directors whose schools compete in either Division I or II in the NCAA, resulting in 96 abd 150 usable responses respectively. Participants in both groups were primarily white males with mean ages of 62 for presidents and 52 for the athletic directors. The study provided demographic information, educational history, professional experience, and prior careers of athletic directors. The rankings of the athletic were compared to the rankings of the presidents and identified consistenncies of opinions. The respondent groups were in agreement on the qualities and ranking of many dimensions of leadershihp in this role. The top seven, for both groups, in order, were ethics, budgeting and finances skills, fundraising, communications, sport leadership, strategic management and policy, and athletic administration. This information could be used as a guide for people who want to strategically maneuver up the ranks in athletics administration. Presidents might use the information as they prepare to hire candidates for the athletic director position.

Highly Stretchable Miniature Strain Sensor for Large Dynamic Strain Measurement

Description: This thesis aims to develop a new type of highly stretchable strain sensor to measure large deformation of a specimen subjected to dynamic loading. The sensor was based on the piezo-resistive response of carbon nanotube(CNT)/polydimethysiloxane (PDMS) composites thin films, some nickel particles were added into the sensor composite to improve the sensor performance. The piezo-resistive response of CNT composite gives high frequency response in strain measurement, while the ultra-soft PDMS matrix provides high flexibility and ductility for large strain measuring large strain (up to 26%) with an excellent linearity and a fast frequency response under quasi-static test, the delay time for high strain rate test is just 30 μs. This stretchable strain sensor is also able to exhibit much higher sensitivities, with a gauge factor of as high as 80, than conventional foil strain gauges.

Decision Makers’ Cognitive Biases in Operations Management: An Experimental Study

Description: Behavioral operations management (BOM) has gained popularity in the last two decades. The main theme in this new stream of research is to include the human behavior in Operations Management (OM) models to increase the effectiveness of such models. BOM is classified into 4 areas: cognitive psychology, social psychology, group dynamics and system dynamics (Bendoly et al. 2010). This dissertation will focus on the first class, namely cognitive psychology. Cognitive psychology is further classified into heuristics and biases. Tversky and Kahneman (1974) discussed 3 heuristics and 13 cognitive biases that usually face decision makers. This dissertation is going to study 6 cognitive biases under the representativeness heuristic. The model in this dissertation states that cognitive reflection of the individual (Frederick 2005) and training about cognitive biases in the form of warning (Kaufmann and Michel 2009) will help decisions’ makers make less biased decisions. The 6 cognitive biases investigated in this dissertation are insensitivity to prior probability, insensitivity to sample size, misconception of chance, insensitivity to predictability, the illusion of validity and misconception of regression. 6 scenarios in OM contexts have been used in this study. Each scenario corresponds to one cognitive bias. Experimental design has been used as the research tool. To see the impact of training, one group of the participants received the scenarios without training and the other group received them with training. The training consists of a brief description of the cognitive bias as well as an example of the cognitive bias. Cognitive reflection is operationalized using cognitive reflection test (CRT). The survey was distributed to students at University of North Texas (UNT). Logistic regression has been employed to analyze data. The research shows that participants show the cognitive biases proposed by Tversky and Kahneman. Moreover, CRT is significant factor to predict the cognitive bias in two ...

Community-based Logistics and Supply Chain Management: Developing, Testing and Validating Conceptual Models

Description: The field of Logistics and Supply Chain Management (LSCM) suggests that transactions, collaboration, and value are important in the supply and delivery of products and services to meet the need of impoverished end-consumers. In many cases, the application of LSCM is paramount in most strategic decision-making efforts. Therefore, this research explores the applications of LSCM processes and activities within the community-based context. The methodology used to address the research questions consisted of a hybrid of mixed methods. This mixed methodology provides three essays that investigate the application and development of LSCM in the community-based context. The essays address the flow of charitable products and services through supply chains. The dissertation does not pay close attention to the first-tier suppliers’ suppliers, which is looking at the originating flow of goods and services (raw materials, manufacturing, etc.). However, the dissertation puts a focus on products and services supplied to focal organizations and how these products are then passed on to end-consumers. Essay I looks at the transaction (costs) that ensue from the supply of charitable products. Essay II analyzes a social service ecosystem and investigates how the network of organizations enable the distribution of charitable products and services. Lastly, Essay III examines the delivery of valuable services to the end-consumers, and what tools Community-Based Enterprises (CBEs) should focus on to develop and retain end-consumers in impoverished communities. The research provides conceptual models that review some fundamental LSCM achievement gaps in supplying, delivering and providing social services to end users within impoverished communities. The dissertation draws upon literature from the fields of economics, marketing, social science, and logistics and supply chain management. The dissertation uses the primary research method of unstructured and semi-structured interviews, case studies, written survey instruments and system dynamics within three studies. The studies resolve to look into the term ...

Ours is the Kingdom of Heaven: Racial Construction of Early American Christian Identities

Description: This project interrogates how religious performance, either authentic or contrived, aids in the quest for freedom for oppressed peoples; how the rhetoric of the Enlightenment era pervades literatures delivered or written by Native Americans and African Americans; and how religious modes, such as evoking scripture, performing sacrifices, or relying upon providence, assist oppressed populations in their roles as early American authors and speakers. Even though the African American and Native American populations of early America before the eighteenth century were denied access to rights and freedom, they learned to manipulate these imposed constraints--renouncing the expectation that they should be subordinate and silent--to assert their independent bodies, voices, and spiritual identities through the use of literary expression. These performative strategies, such as self-fashioning, commanding language, destabilizing republican rhetoric, or revising narrative forms, become the tools used to present three significant strands of identity: the individual person, the racialized person, and the spiritual person. As each author resists the imposed restrictions of early American ideology and the resulting expectation of inferior behavior, he/she displays abilities within literature (oral and written forms) denied him/her by the political systems of the early republican and early national eras. Specifically, they each represent themselves in three ways: first, as a unique individual with differentiated abilities, exceptionalities, and personality; second, as a person with distinct value, regardless of skin color, cultural difference, or gender; and third, as a sanctified and redeemed Christian, guaranteed agency and inheritance through the family of God. Furthermore, the use of religion and spirituality allows these authors the opportunity to function as active agents who were adapting specific verbal and physical methods of self-fashioning through particular literary strategies. Doing so demonstrates that they were not the unrefined and unfeeling individuals that early American political and social restrictions had made them--that instead they were ...

Stable Nanocrystalline Au Film Structures for Sliding Electrical Contacts

Description: Hard gold thin films and coatings are widely used in electronics as an effective material to reduce the friction and wear of relatively less expensive electrically conductive materials while simultaneously seeking to provide oxidation resistance and stable sliding electrical contact resistance (ECR). The main focus of this dissertation was to synthesize nanocrystalline Au films with grain structures capable of remaining stable during thermal exposure and under sliding electrical contact stress and the passing of electrical current. Here we have utilized a physical vapor deposition (PVD) technique, electron beam evaporation, to synthesize Au films modified by ion implantation and codeposited ZnO hardened Au nanocomposites. Simultaneous friction and ECR experiments of low fluence (< 1x10^17 cm^-2) He and Ar ion implanted Au films showed reduction in friction coefficients from ~1.5 to ~0.5 and specific wear rates from ~4x10^-3 to ~6x10^-5 mm^3/N·m versus as-deposited Au films without significant change in sliding ECR (~16 mΩ). Subsurface microstructural changes of He implanted films due to tribological stress were analyzed via site-specific cross-sectional transmission electron microscopy (TEM) and revealed the formation of nanocrystalline grains for low energy (22.5 keV) implantation conditions as well as the growth and redistribution of cavities. Nanoindentation hardness results revealed an increase from 0.84 GPa for as-deposited Au to ~1.77 GPa for Au uniformly implanted with 1 at% He. These strength increases are correlated with an Orowan hardening mechanism that increases proportionally to (He concentration)1/3. Au-ZnO nanocomposite films in the oxide dilute regime (< 5 vol% ZnO) were investigated for low temperature aging stability in friction and ECR. Annealing at 250 °C for 24 hours Au-(2 vol%)ZnO retained a friction coefficient comparable to commercial Ni hardened Au of ~ 0.3 and sliding ECR values of ~35 mΩ. Nanoindentation hardness increases of these films (~2.6 GPa for 5 vol% ZnO) are correlated to ...

Louis Vierne’s Pièces de Fantaisie, Opp. 51, 53, 54, and 55: Influence from Claude Debussy and Standard Nineteenth-Century Practices

Description: The purpose of this research is to document how Claude Debussy’s compositional style was used in Louis Vierne’s organ music in the early twentieth century. In addition, this research seeks standard nineteenth-century practices in Vierne’s music. Vierne lived at the same time as Debussy, who largely influenced his music. Nevertheless, his practices were varied on the basis of Vierne’s own musical ideas and development, which were influenced by established nineteenth-century practices. This research focuses on the music of Louis Vierne’s Pièces de fantaisie, Opp. 51, 53, 54, and 55 (1926-1927). In order to examine Debussy’s practices and standard nineteenth-century practices, this project will concentrate on a stylistic analysis that demonstrates innovations in melody, harmony, and mode compared to the existing musical styles.

Cross-cultural adjustment of self-initiated expatriates and individual work performance.

Description: Globalization in the past few decades has been marked by increased mobility of highly skilled workers from one country to another. Even though self-initiated expatriation is a widespread phenomenon, it is a relatively under-researched phenomenon in the academic literature, especially in an organizational context. Existing literature shows that not all individuals are equally suited to embark on a new life in another country, and self-initiated expatriates (SIEs) could be particularly susceptible to failure since they have no support from a home organization. This study was designed to investigate the experiences of self-initiated professional expatriates and the effect it had on their work performance. The purpose was to understand how their organizational and social experience affected their cross-cultural adjustment process and in turn affected their individual work performance. The researcher used a qualitative method using semi-structured interviews, observations, and documents with ten self-initiated expatriates. This study contributed to the expanding literature on the experiences of self-initiated expatriates, specifically how different support systems affected cross-cultural adjustment and individual work performance.

The Mystery of the Chalumeau and Its Historical Significance as Revealed Through Selected Works for Chalumeau or Early Clarinet by Antonio Vivaldi

Description: Factual evidence concerning the ancestry of the clarinet has been a perpetual topic of debate among musicologists and organologists. Scholars have widely agreed that the clarinet, first documented in 1710, emerged from the baroque invention of the chalumeau (invented circa 1690), which in itself was an improvement upon the recorder. Considering the chalumeau’s short lifespan as the predominant single reed instrument in the early eighteenth century, the chalumeau inspired a monumental amount of literature that includes vocal and instrumental genres written by distinguished composers. Vivaldi is considered to be the most significant composer that wrote for both clarinet and chalumeau; he wrote for both instruments simultaneously throughout his life whereas his contemporaries seemingly replaced the chalumeau with the clarinet. This project will discuss Vivaldi’s proximity to the chalumeau and the clarinet and will provide an in-depth analysis of relevant works by the composer to determine how he, unlike his contemporaries, treated the chalumeau and the clarinet as separate and equally viable instruments. Following a brief history of the chalumeau and clarinet in Italy and a relevant biography of Vivaldi (Ch. 2), this document will discuss the integral Vivaldi compositions that include clarinet and chalumeau and the role of the clarinet or chalumeau in each work (Ch. 3). Chapter 4 solves the mystery of why Vivaldi continued to compose for the chalumeau while his contemporaries replaced the chalumeau with the clarinet.

A Sequential Analysis of Therapist and Child Social Behavior Following a Conditioned Reinforcement Procedure

Description: We conducted a contingency analysis to evaluate if a sequential relation between social initiations and positive social responses increased for both therapists and children with autism following a conditioned reinforcement procedure. Participants included child-therapist dyads, which were previously identified as having low rapport. These dyads were observed prior to and following an intervention designed to establish therapists' social behavior as a reinforcer. Sessions consisted of unstructured play between the therapist and child. Results from a Yule's Q analysis show that both the child and adult positive responding to the others' social initiations increased following the intervention. Findings highlight the reciprocal effects of therapist-child interactions as well as the effectiveness of establishing social attention as a reinforcer via an operant discrimination training procedure.

Transmedia STEM Intervention Book in Middle School for Educational Change

Description: The world is becoming a global place in which science, technology, engineering and mathematics hold a key to a successful future. To help secure this future it is important to engage students early with relevant curriculum that sparks interest and success in STEM fields. However, education reform occurs slowly, so this paper looked at a potential paradigm that can help to bring about change in a middle school environment that harnesses the long standing strengths of learning and education with the integration of technology to create changes in the pedagogy of learners and teachers. The study implemented a transmedia STEM book and evaluated the impact it had on student perceptions of STEM, school attitude, academic achievement, and preferred activity types, providing an example vehicle for change that can be adopted over time. The main findings showed that students who used a 3-Dimensional printer had higher math achievement and a more positive perception of math.

Microstructural Phase Evolution In Laser Deposited Compositionally Graded Titanium-Chromium Alloys

Description: A compositionally graded Ti-xCr (10≤x≤30 wt%) alloy has been fabricated using Laser Engineered Net Shaping (LENSTM) to study the microstructural phase evolution along a compositional gradient in both as-deposited and heat treated conditions (1000°C followed by furnace cooling or air cooling). The alloys were characterized by SEM BSE imaging, XRD, EBSD, TEM and micro-hardness measurements to determine processing-structure-property relations. For the as-deposited alloy, α-Ti, β-Ti, and TiCr2 (C15 Laves) phases exist in varying phase fractions, which were influential in determining hardness values. With the furnace cooled alloy, there was more homogeneous nucleation of α phase throughout the sample with a larger phase fraction of TiCr2 resulting in increased hardness values. When compared to the air cooled alloy, there was absence of wide scale nucleation of α phase and formation of ω phase within the β phase due to the quicker cooling from elevated temperature. At lower concentrations of Cr, the kinetics resulted in a diffusionless phase transformation of ω phase with increased hardness and a lower phase fraction of TiCr2. In contrast at higher Cr concentrations, α phase separation reaction occurs where the β phase is spinodally decomposed to Cr solute-lean β1 and solute-rich β2 resulting in reduced hardness.

Analysis of Factors for Successful State-Level Support of Low-Performing Schools

Description: This study provides a qualitative look at Texas' Professional Service Providers' (PSPs) strategies for supporting low-performing schools. Four PSPs were selected for participation based on the number of schools they helped exit the Texas Title I School Improvement Program from 2007-2012. Data collected and analyzed included provider and principal interviews, providers' progress reports documenting services, and principals' evaluations of provider services. Results indicated key support strategies in two of four cases were supporting and mentoring/coaching while communicating and building trust were important in the other two cases. Communicating, reviewing information, and planning were important across all cases. The quality indicators aligning with the PSPs' strategies were fit, comprehensiveness, and coherence. They were also the most common across all cases. Finally, analysis of the evaluation of provider services revealed PSP-1 with the highest ratings, followed by PSP-2, PSP-3, and PSP-4 respectively. The findings suggest, first, that PSP support has a dual nature. Contextual support was provided based on the campus leaderships' skills and requests. PSPs also ensured coherence among the strategies of all stakeholders. Secondly, a hierarchy of quality service indicators aligned to the PSPs' strategies: fit, comprehensiveness, and coherence. Finally relationships are vital to a successful provider-campus relationship. The findings have implications for PSP selection, professional development, and evaluation.

Social-Emotional Competencies of African American Children: Impact of Child-Centered Play Therapy

Description: African American children experience risks due to heightened socio-environmental problems and responding to negative racial messages in their environments. Child Centered Play Therapy (CCPT) is one viable intervention for the development of social emotional competence among African American children to help mediate adverse conditions. I sought to explore the effects of CCPT on the social emotional competencies of African American children utilizing Social Emotional Assets and Resilience Scale-Parent & Teacher (SEARS-P; SEARS-T) reports. Thirty-seven African American participants with a mean age of 6.68 years were recruited from four suburban elementary schools in the southwest U.S. Twenty participants were randomly assigned to the intervention group receiving a mean of 13.3 CCPT sessions over 8 weeks, and 17 participants were assigned to the waitlist control group. Factorial ANOVA results indicated that parents reported statistically and practically significant improvement for children who participated in CCPT in overall social-emotional competencies. Follow-up analysis revealed statistical and practical improvement in children’s empathy, as well as practical improvement in self-regulation/responsibility and social competence. Teacher-reported results indicated practical but non-statistically significant improvement in overall social-emotional competencies for children who participated in CCPT, including statistical and practical improvement in children’s responsibility, as well as practical improvement in self-regulation, social competence, and empathy. Thus, CCPT showed promise as a culturally responsive treatment intervention to improve African American children’s social-emotional competencies

The Contemporary Bassoonist: Music for Interactive Electroacoustics and Bassoon

Description: As the bassoon has evolved over time, the music written for the instrument has evolved around it, and was many times the catalyst for its evolution. Bassoon music of the seventeenth through early twentieth centuries has defined much of the curricula for bassoon studies, and has established how we consider and experience the bassoon. We experience, write, and consume music in vastly different ways than just a generation ago. Humans use technology for the most basic of tasks. Composers are using the technology of our generation to compose music that is a reflection of our time. This is a significant aspect of art music today, and bassoonists are barely participating in the creation of this new repertoire. Performance practice often considers only the musical score; interactive electronic music regularly goes beyond that. The combination of technological challenges and inexperience can make approaching electroacoustic music a daunting and inaccessible type of music for bassoonists. These issues require a different language to the performance practice: one that addresses music, amplification, computer software, hardware, the collaboration between performer and technology, and often the performer and composer. The author discusses problems that performers face when rehearsing and performing interactive electroacoustic works for bassoon, and offers some solutions.

Performance Evaluation of UNT Apogee Stadium Wind Turbines

Description: The following report chronicles the University of North Texas Wind Turbine Project at Apogee Stadium. The timeline of events will include the feasibility study conducted by and for the university, grant awards from the Texas State Energy Conservation Office to fund the project, and a three-year sample of real time performance data since installation. The purpose of this case study is to compare the energy generation estimates by various stakeholders to the measured energy generation using a new but uniform performance relationship. In order to optimize energy generation in wind turbine generator systems, the most common wind speeds measured at the site should also be the most efficient wind speeds at which the wind turbine can convert the kinetic energy in the wind into mechanical energy and ultimately electrical energy. The tool used to convey this relationship will be a figure plotting the wind speed profile against the efficiency curve of the wind turbine. Applying this relationship tool to the UNT Apogee Stadium wind turbines provided valuable results. The most common wind speeds at Apogee Stadium are not the most efficient wind speed for the turbine. Also, the most common wind speeds were near the lower limit of the wind turbine’s performance parameters. This scenario was evident in both the energy generation predictions as well as the real-time recorded data. This case study will also present the economic analysis of the Apogee Stadium wind turbines using another tool that was not previously used in the feasibility study. The case study concludes with future steps to improve wind turbine performance, and to budget future cost using past, present and future energy savings.

Manhood in Spain: Feminine Perspectives of Masculinity in the Seventeenth Century

Description: The question of decline in the historiography of seventeenth-century Spain originally included socio-economic analyses that determined the decline of Spain was an economic recession. Eventually, the historiographical debate shifted to include cultural elements of seventeenth-century Spanish society. Gender within the context of decline provides further insight into how the deterioration of the Spanish economy and the deterioration of Spanish political power in Europe affected Spanish self-perception. The prolific Spanish women writers, in addition, featured their points of view on manhood in their works and created a model of masculinity known as virtuous masculinity. They expected Spanish men to perform their masculine duties as protectors and providers both in public and in private. Seventeenth-century decline influenced how women viewed masculinity. Their new model of masculinity was based on ideas that male authors had developed, but went further by emphasizing men treating their wives well.

Taxpayer compliance from three perspectives: A study of economic, environmental, and personal determinants.

Description: Tax evasion is a serious issue that influences governmental revenues, IRS enforcement strategies, and tax policy decisions. While audits are the most effective method of enforcing compliance, they are expensive to conduct and the IRS is only able to audit a fraction of the returns filed each year. This suggests that audits alone are not sufficient to curb the billions of dollars of tax evaded by taxpayers each year and that a better understanding of factors influencing compliance decisions is needed to enable policymakers to craft tax policies that maximize voluntary compliance. Prior research tends to model compliance as economic, environmental, or personal decisions; however, this study models it as a multifaceted decision where these three perspective individually and interactively influence compliance. It is the first to decompose perceived detection risk into two dimensions (selection risk and enforcement risk) and investigates how these two dimensions of risk, decision domains (refund or tax due positions), and three personal factors (mental accounting, narcissism, and proactivity) influence taxpayers’ compliance decisions. I conducted a 2x2 fully crossed experiment involving 331 self-employed taxpayers. These taxpayers have opportunities to evade that employed taxpayers do not. For example, they can earn cash income that is not reported to the IRS by third parties. For self-employed taxpayers (especially those wanting to evade), perceived selection and enforcement risks may be distinctly different depending on a taxpayer’s situation, what they believe they can control, and what risk they are willing to accept. For example, selection risk may be perceived as the greatest risk for those with unreported items on their return, while enforcement risk may be more prominent for those perceiving certain levels of selection risk. Thus, I believe self-employed taxpayers are the most appropriate population to sample from and are likely have reasonable variation in the three personal factors ...

Physician Leadership and Self Efficacy: A Case Study Using Grounded Theory

Description: Bombarded by constant and rapid change, healthcare organizations feel a sense of urgency to meet their needs for leaders. They rely on physicians to lead at all levels in their healthcare organizations. For them to successfully navigate today's healthcare environment, they require more than a medical education. To address this need, healthcare organizations are developing in-house leadership development programs.In this paper, I conduct a case study of physicians transitioning into leadership and their self-efficacy facilitated through an in-house leadership development program. Documentation, semi-structured interviews, and observations are examined to explore how physicians think about their leadership experiences following their participation in a six-month leadership development program.The study also explores at a high-level how these experiences influenced physician's self-efficacy as a first step in developing a theory of physician leadership and self-efficacy.

An Analytical Study of Paradox and Structural Dualism in the Music of Ludwig van Beethoven

Description: Beethoven's rich compositional language evokes unique problems that have fueled scholarly dialogue for many years. My analyses focus on two types of paradoxes as central compositional problems in some of Beethoven's symphonic pieces and piano sonatas. My readings of Beethoven's Piano Sonata No. 27 (Op. 90), Symphony No. 4 (Op. 60), and Symphony No. 8 (Op. 93) explore the nature and significance of paradoxical unresolved six-four chords and their impact on tonal structure. I consider formal-tonal paradoxes in Beethoven's Tempest Sonata (Op. 31, No. 2), Ninth Symphony (Op. 125), and Overture die Weihe des Hauses (Op. 124). Movements that evoke formal-tonal paradoxes retain the structural framework of a paradigmatic interrupted structure, but contain unique voice-leading features that superimpose an undivided structure on top of the "residual" interrupted structure. Carl Schachter's observations about "genuine double meaning" and his arguments about the interplay between design and tonal structure in "Either/Or" establish the foundation for my analytical approach to paradox. Timothy Jackson's reading of Brahms' "Immer leiser word meine Schlummer" (Op. 105, No. 2) and Stephen Slottow's "Von einem Kunstler: Shapes in the Clouds" both clarify the methodology employed here. My interpretation of paradox involves more than just a slight contradiction between two Schenkerian readings; it involves fundamentally opposed readings, that both result from valid, logical lines of analytical reasoning. In my view, paradoxes could be considered a central part of Beethoven's persona and philosophy. Beethoven's romantic endeavors and his relationships with mentors suggest that paradoxes might have been central to his bravura. Furthermore, Beethoven's familiarity with the politics of the French Revolution and Shakespearean literature suggest that paradoxes in some pieces (including the Ninth Symphony) could be metaphorical representations of his ideology. However, I do not attempt to explicitly link specific style features to extra-musical ideas. Modern Schenkerian scholars continue to expand ...
