During the annual meeting of the MidAmerican Conference Band Directors Association at the Midwest Clinic in Chicago (December, 2003) it was proposed and accepted to conduct a comprehensive study describing and discussing issues and topics related to the athletic band programs of the MAC. During the meeting a model survey instrument, based on the studies of Holvik (1971), Patzig (1983), and Fuller (1995) was presented. Revisions were made by the MAC athletic band directors refreshing the model to include additional topics of value to the Association. During the spring and summer of 2004 the model was reviewed by a panel of collegiate band directors who agreed to serve as readers and advisors. In its final form the questionnaire focused on 33 topics. In April 2005, the questionnaire was sent to the 14 athletic band directors of the MAC via email in a Microsoft Excel Spreadsheet format. The spreadsheet version, presented on CD-ROM, and a standard hard copy were sent via U.S. Mail. All of the athletic band directors responded fully and positively resulting in a comprehensive collection of data describing the staffing, administration, rehearsal and performance practices, traditions and trends of the athletic bands of the MAC. Survey questions concerning contemporary topics, updating the three model studies, produced information on: the evolution of professional title to “Director of Athletic Bands”, access to and use of technologies in planning and instruction, the affect of athletic department game management and marketing efforts, and the nature of university and community efforts to address sportsmanship issues that affect athletic bands

Canada's military maintains a permanent detail of about twelve hundred enlisted trained musicians. Central to raising morale and promoting esprit-de-corps, music has always played a role in the Canadian military, but it rarely draws any sort of critical attention. I explore the practical and social functions of military musicians within the part-time military context of the Canadian Armed Forces Reserve Force, and consider how musicians reconcile music-making with the goals and objectives of a combat-driven organization. Adopting an ethnographic approach, this dissertation offers an on-the-ground analysis of how musicians belonging to three bands in the city of Toronto create distinctive musical pathways traversing aesthetic enjoyment, social interaction, and soldierly ethos. Broadly, this study probes the connection between martial and musical performance, and reveals what kind of impact soldiering has on music and musicians, and how music helps to shape a military environment that reflects Canadian national identity.

The subculture of jam bands is often publicly held to multiple stereotypical expectations. Participants in the subculture are expected to fall into one of two camps, coastal elites or “dirty hippies.” Members of the Northwest Ohio jam scene often do not have the kind of economic privilege that is assumed of them based on the larger jam subculture. Not only do these perceptions create difficulties for audience members of the Northwest Ohio scene, but there are added complications for the musicians in the scene. This research explores the challenges of class and belonging faced by participants in the Northwest Ohio jam scene. More specifically, this thesis focuses on the careful social negotiations scene members and musicians are required to navigate in order to maintain insider status while dealing with the working-class realities of life in the area. In this thesis, I argue that subcultural capital is one of the most significant factors for belonging to the larger subculture, and that its necessity, which requires sufficient economic support, demands more nuanced practices by local scenesters in order to maintain. I dissect the complexities of the concept of “family” in the jam scene, including its meaning for audiences and musicians, as well as how it intersects with class and public perceptions of class in the scene. Finally, I argue that musical forms and practices hold significance in establishing genre authenticity, but I maintain that class is a determining factor in the decisions bands make about whether or not they hold completely true to genre boundaries. This thesis attempts to address the complexities of class and how it functions in small, local rock scenes, specifically in the Northwest Ohio jam scene.

Faults are structural discontinuities in the upper crust that are responsible for earthquake hazards. The damage zone that surrounds faults consist of a complex network of brittle structures (e.g., fractures) that can extend up to several hundred meters from the principal slip zone along large mature faults. These structural features potentially hold information about faulting processes and could be useful in probabilistic seismic hazard assessments. One key clue that the structure of fault damage zones may hold information regarding the potential size of future earthquakes comes from a comparison of facture energy (G) measured from laboratory rotary shear experiments and natural earthquakes (Nielsen et al., 2016). Whereas these numbers are equivalent for small earthquakes, G for large natural earthquakes far exceeds that of laboratory measurements for equivalently sized events, causing seismologists to speculate that a significant portion of the earthquake energy budget for large earthquakes is dissipated in permanent off-fault deformation. These seismologists have posited that across the moment magnitude range (e.g., Mw6.6-6.8), the earthquake energy budget undergoes an important transition wherein energy dissipation by inelastic off-fault damage constitutes an increasingly significant fraction of the total breakdown energy (Nielsen et al., 2016). In this thesis, I attempt to investigate this hypothesis by examining the damage zones along two faults in Southern California: the Elsinore and Superstition Hills Fault. These faults have hosted recent earthquakes of approximately to Mw6.8 and Mw6.6 respectively. The damage zones surrounding these faults differ significantly in size and fracture density despite belonging to the same tectonic environment and being formed in similar sandstone lithologies. We conducted fieldwork near the entrance to Fossil Canyon in the Coyote Mountains where the Elsinore Fault crosses the Imperial Formation and at Imler Road (open full item for complete abstract)

The search for new quantum mechanical phenomena by manipulating the electronic and transport properties of two-dimensional material have become an active research topic in the last decade. Among all the two dimensional materials, graphene got most of the attention due to its fascinating electronic and mechanical properties. Substrates are usually used to support graphene in experiments. The interactions between the substrate and graphene layer result into deformations in the system due to strain. Numerous techniques have already been developed to alter the local density of states and the band structure of graphene. Novel approaches implement engineered substrates to induce specifically targeted strain profiles. Inspired by this technique, we study the evolution of charge distribution with an increasing number of out-of-plane Gaussian deformations. This deformation profile serves as an introduction to model a finite size periodic substrate. We begin with a system of two overlapping deformations and determine the quantitative relations between its geometrical parameters and features in the local density of states. Extending the study to sets of three and four deformations in linear and two-dimensional arrays we observed the emergence of moire0 pattern in charge distributions. These moire0 patterns are more robust for an hexagonal cell composed of seven Gaussian bubbles. A comparison between the induced strain profiles and spatial maps of local density of states at different energies provides evidence of the existence of pseudo-magnetically confined states in the deformed regions. These confined states indicate the possibility of creating quantum dots in graphene via strain modulations. These states exhibit a linear dependence in the energy scaling in contrast to the scaling of pseudo-Landau levels. We further extend these studies to periodic deformation profiles with different periodicity other than the4 graphene lattice, creating a 'superlattice (open full item for complete abstract)

We extend an Effective Field Theory (EFT) developed to describe rotational bands in even-even nuclei to the odd-mass case. This organizes Bohr & Mottelson's treatment of a particle coupled to a rotor as a model-independent expansion in powers of the angular velocity of the overall system. We carry out this expansion up to fourth order in the angular velocity and present results for 99Tc, 159Dy, 167,169Er, 167,169Tm, 183W, 235U and 239Pu. In each case, we get clear systematic improvement, as we go to higher orders in our EFT, starting form simple low energy degrees of freedom. We clearly show the main benefit of this EFT by using a Bayesian analysis framework to properly and rigorously account for theoretical uncertainty. We make use of the EFT expansion to perform a Bayesian analysis of data on the rotational energy levels of the nuclei above and in 155Gd and 157Gd. The error model in our Bayesian analysis includes both experimental and EFT truncation uncertainties. It also accounts for the fact that low-energy constants (LECs) at even and odd orders are expected to have different sizes. We use Markov Chain Monte Carlo (MCMC) sampling to explore the joint posterior of the EFT and error-model parameters and show both the LECs and the breakdown scale can be reliably determined. We extract the LECs up to fourth order in the EFT and find that, provided we correctly account for EFT truncation errors in our likelihood, results for lower-order LECs are stable as we go to higher orders. LEC results are also stable with respect to the addition of higher-energy data. We extract the expansion parameter for all the nuclei listed above and find a clear correlation between the extracted and the expected value of the inverse breakdown scale, W, based on the single-particle and vibrational energy scales. However, the W that actually determines the convergence of the EFT expansion is markedly smaller than would be naively expected based on those scales.

The thesis deals with three fundamental problems lying at the intersection of correlations and topology in quantum materials. They are further divided into two broad classes: superconductivity in strongly correlated systems and Hall effect in chiral magnets. The first questions what material parameters control the superconducting (SC) transition temperature $T_c$. In many novel superconductors, SC phase fluctuations determine $T_c$, rather than the collapse of the pairing amplitude. We derive rigorous upper bounds on the superfluid phase stiffness for multi-band systems, valid in any dimension. This in turn leads to an upper bound on $T_c$ in two dimensions (2D), which holds irrespective of mechanism, pairing interaction strength, or order-parameter symmetry. We first show that $k_BT_c \leq E_F/8$ for a single parabolic band in 2D with Fermi energy $E_F$, a result that has direct implications for systems as diverse as Li-doped ZrNCl and the 2D BCS-BEC crossover in ultra-cold Fermi gases. We further derive bounds on monolayer FeSe on STO and magic-angle twisted bilayer graphene (MA-TBG) using the available band structures. We then discuss the question of deriving rigorous upper bounds on $T_c$ in 3D. In the second project, we present exact results that give insight into how interactions lead to transport and superconductivity in a flat band where the electrons have no kinetic energy. We obtain bounds for the optical spectral weight for flat band superconductors. We focus on on-site attraction $|U|$ on the Lieb lattice with trivial flat bands and on the $\pi$-flux model with topological flat bands. For trivial flat bands, the low-energy optical spectral weight $\widetilde{D}_\text{low} \leq \widetilde{n} |U| \Omega/2$ with $\widetilde{n} = \min\left(n,2-n\right)$, where $n$ is the flat band density and $\Omega$ the Marzari-Vanderbilt spread of the Wannier functions (WFs). We also obtain a lower bound involving the quantum metric. For topological flat bands, wit (open full item for complete abstract)

Despite calls to broaden and diversify course offerings in music education, many music programs remain focused on large ensembles such as band, choir, and orchestra. One way to expand music programs can be through the inclusion of non-traditional music ensembles. An example of a non-traditional music ensemble is a rock band. This convergent mixed design study surveyed high school music teachers in the state of Ohio (N = 73) on their perspectives toward the inclusion of rock ensembles in their high school music classrooms. Statistical analyses showed a moderate relationship between jazz ensembles and rock bands and suggested that teachers who prefer and feel prepared to teach jazz may be more likely to offer a rock ensemble (p < .05). The results from open ended questions indicated complexity within teachers' factors surrounding the inclusion of rock band ensembles in a music curriculum. Teachers reported a variety of factors that would motivate or prevent them from offering rock ensembles, which included a fear of losing students from traditional ensembles and concern that students would be too busy to participate in a new ensemble. Furthermore, this study indicates that music teachers feel that they need training to feel more comfortable in offering non-traditional ensembles such as rock bands. The results of this study could have implications for both collegiate music education programs and high school music programs. University music education programs may consider creating a course in popular music pedagogy or incorporating popular music pedagogy into current methods courses. High school music programs may consider incorporating elements of rock music into established jazz programs.

Currently, there is limited information regarding the activation of muscles in the upper extremities during prehabilitation techniques in baseball pitchers. Prehabilitation exercises are widely used prior to games to prepare the body ready to perform at the highest level. A common prehabilitation activity that is done with baseball pitchers are J-Bands. J-Bands are used at almost every level of baseball as a warmup technique for pitchers before they go into a game to pitch. This study compared the muscle activity in the triceps and serratus anterior in 14 different male pitchers during two different bullpen sessions. The triceps and serratus anterior were the two muscles chosen to test because they are two of the most active muscles in the entire pitching motion for a pitcher. The first session would be with the use of the J-Band warmup while the second session would be a standard warm-up without the use of a J-Band warmup. The differences between the muscle activity after throwing 5 pitches in each session was calculated. Independent sample t tests revealed a significant difference in the average triceps activity between the standard session and the J-Band session. The average muscle activity in the triceps was much greater during the 5-pitch session with the J-Band warmup compared to the warmup without using the J-Bands. No other significant differences were found in the peak triceps muscle activity or the average or peak muscle activity in the serratus anterior. These results indicate that the J-Band warmup was generally more catered to the upper arm extremity compared to the muscles surrounding the back or serratus anterior. The results show that the J-Band prehabilitation warm-up is effective overall.

In musical interpretation and the conveyance of performance aspects, instrumental conductors play a fundamental role. Particularly during rehearsal, the conductor is tasked with identifying ensemble errors and unifying the ensemble. While research exists on the generalized rehearsal, little has been done on the actions and techniques the conductor utilizes while the group is playing. Through a survey of 41 questions distributed to various conductors and instrumental players across Ohio, participants were asked to identify which actions were used by their conductor, how often they were used, and how effective they felt the actions were to the performance and improvement of their group. Such actions include modeling by playing an instrument, giving cues during group playing, showing dynamics with pattern size, mirroring, refraining from conducting, and various others. The study breaks down each action and discusses their effectiveness based on the survey results to identify best practices when conducting a group ensemble.

Chi Ma, University of Akron, May 2019. Improving the plasticity of metallic glass through heterogeneity induced by electropulsing-assisted surface severe plastic deformation. Advisor: Yalin Dong. Co-advisor: Chang Ye. Metallic glasses have raised tremendous interests to industrial and academic community due to its superior properties (e.g. ultimate strength, wear resistance, and soft-magnetic property) since their invention. The amorphous structure, on the one hand, gives rise to advanced material properties while, on the other hand, causes poor ductility hindering the wide application of metallic glasses. Aiming at designing ductile metallic glasses, this thesis research investigates surface severe plastic deformation (SSPD), electropulsing, and their combined treatment to achieve the transition from brittle to ductile, and unveil the relationship between microstructure and mechanical deformation behavior through molecular dynamics simulation and fracture theory. Ultrasonic nano-crystal surface modification (UNSM), as a member of the SSPD family, is a recent developed technology possessing high controllability and good surface finish. By applying ultrasonic mechanical peening, UNSM leads to the dilation of local atomic structure and thus induces extra free volume heterogeneously. Extra free volume is generated after UNSM treatment and consequently plasticity, i.e. yielding and more plastic strain, starts to appear. The observation of fracture surface suggests that before fracture occurs, higher density of shear bands exists in the UNSM-treated samples and severe interaction between shear bands impedes propagation of themselves, which contributes to material plasticity. In addition to extra free volume, the secondary crystalline phase induced by UNSM and its effect on increasing plasticity is also explored. In this thesis, for the first time, the composite structure of nanocrystalline phase co-existed with extra free volume is fabricated by electropulsing-ass (open full item for complete abstract)
