Show moreThis dissertation investigates the resources that students use to learn new digital technologies to complete course assignments. This work is particularly important in a time when teachers are assigning more multimodal projects. If students are using and learning digital technologies to complete our assignments, we might argue that we should teach our students how to use the specific technologies they would use for the assignment. Yet, teaching students specific technologies is complicated for several reasons, including limited time and resources, numerous and quickly obsolete software, different levels of expertise for students and teachers, and more. Because of these complications, students may benefit from spending less time with instruction in specific technologies and more time considering practices for learning new digital technologies. This dissertation works to discover practices that teachers can use in the classroom to help their students learn how to learn new digital technologies in order to compose multimodal texts. To do this, I investigate how students are already learning technologies outside of the classroom and use this investigation to identify possible pedagogical directions. To gain a broader understanding of the resources students are using, I surveyed five sections of an upper-level composition course in which students completed at least one digital assignment. Then, to gain a more nuanced and richer description of resource use, I interviewed three of these students. To analyze the data, I used a framework adapted from Jeanette R. Hill and Michael J. Hannafin's components for Resource-Based Learning (RBL). RBL is a pedagogical approach that aims to teach students how to learn and to produce students who are self-directed problem-solvers, able to work both collaboratively and individually. Though RBL is a pedagogical approach, I used its values and parameters as a lens for understanding students' use of resources. RBL (as the name suggests) puts emphasis on the resources students use to facilitate their learning. Given the wide variety of resources and the ways in which they can be used in the classroom, few scholars articulate precisely what RBL may look like more generally. Hill and Hannafin (2010), however, list four components among which RBL can vary: resources, tools, contexts, and scaffolds. In this study, resource is an umbrella term for the tools, contexts, and humans students may use to support their learning. Tools are the non-human objects that students use to learn new technologies. Humans are the people from whom students seek help. Contexts are the rhetorical situations (specifically the audiences and purposes for composing) surrounding the technological learning, the students' past technological experiences, and the physical locations in which students work. An important element of this study is to identify not only what resources students use, but also how they use their resources; scaffolds are how the resources are used. The scaffolds in this study are as follows: conceptual scaffolds – resources help students decide the order in which to complete tasks, understand the affordances and constraints of the technology, and learn the genre conventions of a given text; metacognitive scaffolds – resources help students tap into their prior knowledge; procedural scaffolds – resources provide students with step-by-step instructions for completing tasks or with definitions of vocabulary; and strategic scaffolds – resources encourage students to experiment in order to learn and solve problems they encounter while learning the technology. In addition to addressing what and how students use resources to learn to perform tasks with the technology, I also examined how students used resources to learn the specialized vocabulary of the technology and the technology's affordances and constraints. The study resulted in eight findings about the ways in which students are using resources. These findings were then used to identify three areas for possible strategies teachers might consider to help students use resources to learn new technologies: 1. Helping students effectively choose technologies, which includes assisting them in (a) using resources to identify technology options and learn about the affordances and constraints of the options and (b) using the affordances and constraints, their composing situations, and the available resources to choose the technology that best meets their needs. 2. Helping students effectively use templates, which includes aiding them in (a) using templates to learn about the genres in which they are composing, (b) selecting effective templates, and (c) altering the templates based on their rhetorical situations and preferences. 3. Helping students learn the technology's specialized vocabulary, which includes assisting them in (a) identifying familiar visual and linguistic vocabulary, (b) making educated guesses about unfamiliar vocabulary, and (c) using resources to learn unfamiliar vocabulary.

Show moreThis dissertation explores the founding of the National Federation of Music Clubs (NFMC) in 1898 and focuses upon the organization's activities from its beginning to 1920. It highlights how the original members were able to build a strong and influential institution that continues to support American music and musicians today. The creation of the NFMC is a result of two developments that occurred simultaneously during the nineteenth-century in the United States: 1) the proliferation of voluntary associations and organized reform movements and 2) the emergence of high art music culture across the nation. This project applies gender theory to examine the development of the notion of the domestic sphere as the appropriate domain for the female sex in the nineteenth century, and how women reacted to dominant ideologies through voluntary organizations that broadened their world. It also utilizes recent scholarship in women's history, social history, early American history, and institutional studies to present a survey of the types of organizations that formed and how they changed in response to the social and historical context. Even though the NFMC was originally a women's institution run by and for women, its larger goal was to disseminate art music culture through local club activities across the nation to all citizens. The growth of women's music clubs was part of the post-civil war boom of women's culture clubs. The concept of music as art developed and spread steadily during the nineteenth century, and at first the music clubs specifically cultivated art music based on western European traditions, which was associated with high class refinement. European ideals were perpetuated by an influx of European touring virtuosos and groups during the first half of the nineteenth century. In her article titled "Art Music from 1800 to 1860," Katherine K. Preston explains that the polished concerts performed by touring musicians not only circulated art music among Americans, but they also introduced higher performance standards, which resulted in increasingly higher expectations for refined performances from American audiences starting in the 1820s and 1830s and surging after 1840. These performances were supported and promoted by patrons and institutions, which ultimately led to the growth of art music appreciation as a movement throughout the nation. Michael Broyles clarifies that even though European style was dominant during the nineteenth century, American musical culture was uniquely formed by "historical events that have no European counterpart." He states that institutions controlled the character of the music in the United States. The support and dissemination of American art music happened through a combination of civic, philanthropic, private, and entrepreneurial activities, which included: the spread of art music through touring virtuosos and ensembles on a much larger scale than the first half of the nineteenth century, women's music clubs, orchestras, monster concerts and festivals, an increase in the number of American-born composers during the late nineteenth century, and a growing sense of patriotism at the turn of the century. During the late nineteenth and into the early twentieth centuries, women's music clubs became one of the most effective cultivators of classical music in the United States through their strong infrastructure and collaboration with prominent musicians, critics, and pedagogues. This project highlights the integral role of the NFMC's activities in many of the significant developments in the history of American music at this time. No other institution has been as ubiquitous or influential as the NFMC in the musical growth of the United States. This dissertation is the first detailed exploration of the history of this powerful institution.

Show moreA growing impulse in American black female fiction is the reclamation of black female sexuality due to slavery's proliferation of sexual stereotypes about black women. Because of slave law's silencing of rape culture, issues of consent, will, and agency become problematized in a larger dilemma surrounding black humanity and the repression of black female sexuality. Since the enslaved female was always assumed to be willing, because she is legally unable to give consent or resist, locating black female desire within the confines of slavery becomes largely impossible. Yet, contemporary re-imaginings of desire in this context becomes an important point of departure for re-membering contemporary black female subjectivity. "What's Love Got to Do With It?" is an alternative look at master-slave relationships, particularly those between white men and black women, featured in contemporary slave narratives by black women writers. Although black feminist critics have long considered love an unavailable, if not, unthinkable construct within the context of interracial relationships during slavery, this project locates this unexpected emotion within four neo-slave narratives. Finding moments of love and desire from, both, slaveholders and slaves, this study nuances monolithic historical players we are usually quick to adjudicate. Drawing on black feminist criticism, history, and critical race theory, this study outlines the importance of exhuming these historic relationships from silence, acknowledging the legacies they left for heterosexual love and race relations, and exploring what lessons we can take away from them today. Recognizing the ongoing tension between remembering and forgetting and the inherent value in both, this study bridges the gap by delineating the importance of perspective and the stories we choose to tell. Rather than being forever haunted by traumatic memories of the past and proliferating stories of violence and abuse, Barbara Chase-Riboud, Octavia Butler, Gayle Jones, and Gloria Naylor's novels reveal that there are ways to negotiate the past, use what you need, and come to a more holistic place where love is available.

Show moreControl of aerodynamic noise generated by high-performance jet engines continues to remain a serious problem for the aviation community. Intense low frequency noise produced by large-scale coherent structures is known to dominate acoustic radiation in the aft angles. A tremendous amount of research effort has been dedicated towards the investigation of many passive and active flow control strategies to attenuate jet noise, while keeping performance penalties to a minimum. Unsteady excitation, an active control technique, seeks to modify acoustic sources in the jet by leveraging the naturally-occurring flow instabilities in the shear layer. While excitation at a lower range of frequencies that scale with the dynamics of large-scale structures, has been attempted by a number of studies, effects at higher excitation frequencies remain severely unexplored. One of the major limitations stems from the lack of appropriate flow control devices that have sufficient dynamic response and/or control authority to be useful in turbulent flows, especially at higher speeds. To this end, the current study seeks to fulfill two main objectives. First, the design and characterization of two high-frequency fluidic actuators ($25$ and $60$ kHz) are undertaken, where the target frequencies are guided by the dynamics of high-speed free jets. Second, the influence of high-frequency forcing on the aeroacoustics of high-speed jets is explored in some detail by implementing the nominally 25 kHz actuator on a Mach 0.9 ($Re_D = 5\times10^5$) free jet flow field. Subsequently, these findings are directly compared to the results of steady microjet injection experiments performed in the same rig and to prior jet noise control studies, where available. Finally, limited acoustic measurements were also performed by implementing the nominally 25 kHz actuators on jets at higher Mach numbers, including shock containing jets, and elevated temperatures. Using lumped element modeling as an initial guide, the current work expands on the previous development of low-frequency (2-8 kHz) Resonance Enhanced Micro-actuators (REM) to design actuators that are capable of producing high amplitude pulses at much higher frequencies. Extensive benchtop characterization, using acoustic measurements as well as optical diagnostics using a high resolution micro-schlieren setup, is employed to characterize the flow properties and dynamic response of these actuators. The actuators produced high-amplitude output a range of frequencies, $20.3-27.8$ kHz and $54.8-78.2$ kHz, respectively. In addition to providing information on the actuator flow physics and performances at various operating conditions, the benchtop study serves to develop relatively easy-to-integrate, high-frequency actuators for active control of high-speed jets for noise reduction. Following actuator characterization studies, the nominally 25 kHz ($St_{DF} \approx 2.2$) actuators are implemented on a Mach 0.9 free jet flow field. Eight actuators are azimuthally distributed at the nozzle exit to excite the initial shear layer at frequencies that are approximately an order of magnitude higher compared to the \textit{jet preferred frequency}, $St_P \approx 0.2-0.3$. The influence of control on the mean and turbulent characteristics of the jet, especially the developing shear layer, is examined in great detail using planar and stereoscopic Particle Image Velocimetry (PIV). Examination of cross-stream velocity profiles revealed that actuation leads to strong, spatially coherent streamwise vortex pairs which in turn significantly modify the mean flow field, resulting in a prominently undulated shear layer. These vortices grow as they convect downstream, enhancing local entrainment and significantly thickening the initial shear layer. Azimuthal inhomogeneity introduced in the jet shear layer is also evident in the simultaneous redistribution and reduction of peak turbulent fluctuations in the cross-plane near the nozzle exit. Further downstream, control results in a global suppression of turbulence intensities for all axial locations, also evidenced by a longer potential core and overall reduced jet spreading. The resulting impact on the noise signature is estimated via far-field acoustic measurements. Noise reduction was observed at low to moderate frequencies for all observation angles. Direct comparison of these results with that of steady microjet injection revealed some notable differences in the initial development of streamwise vorticity and the redistribution of peak turbulence in the azimuthal direction. However, despite significant differences in the near nozzle aerodynamics, the downstream evolution of the jet appeared to approach near similar conditions with both high-frequency and steady microjet injection. Moreover, the impact on far-field noise was also comparable between the two injection methods as well as with others reported in the literature. Finally, for jets at higher Mach numbers and elevated temperatures, the effect of control was observed to vary with jet conditions. While the impact of the two control mechanisms were fairly comparable on non-shock containing jets, high-frequency forcing was observed to produce significantly larger reductions in screech and broadband shock-associated noise (BBSN) at select under-expanded jet conditions. The observed variations in control effects at different jet conditions call for further investigation.

Show moreWingtip vortices develop at the tips of aircraft wings due to a pressure imbalance during the process of generating lift. These vortices significantly increase the total aerodynamic drag of an aircraft at high-lift flight conditions such as during take-off and landing. The long trailing vortices contain strong circulation and may induce rolling moments and lift losses on a trailing aircraft, making them a major cause for wake turbulence. A mandatory spacing between aircraft is administered by civil aviation agencies to reduce the probability of hazardous wake encounters. These measures, while necessary, restrict the capacity of major airports and lead to higher wait times between take-off and landing of two aircraft. This poses a major challenge in the face of continuously increasing air traffic volume. Wingtip vortices are also known as a potent source of aerodynamic vibrations and noise. These negative effects have made the study of wingtip vortex attenuation a critical area of research. The problem of induced drag has been addressed with the development of wingtip device, like winglets. Tip devices diffuse the vortex at its very onset leading to lower induced drag. The problem of wake turbulence has been addressed in studies on vortex interactions and co-operative instabilities. These instabilities accelerate the process of vortex breakdown, leading to a lower lifetime in the wake. A few studies have tried to develop active mechanisms that can artificially excite these instabilities. The aim of the present study is to develop a device that can be used for both reducing induced drag and exciting wake instabilities. To accomplish this objective, an active winglet actuator has been developed with the help of piezoelectric Macro-Fiber Composite (MFC). The winglet is capable of oscillating about the main wing-section at desired frequency and amplitude. A passive winglet is a well-established drag reducing device. An oscillating winglet can introduce perturbations that can potentially lead to instabilities and accelerate the process of vortex breakdown. A half-body model of a generic aircraft configuration was fabricated to characterize and evaluate the performance of actuated winglets. Two winglet models having mean dihedral orientations of 0° and 75° were studied. The freestream velocity for these experiments was 20 m/s. The angle of incidence of the wing-section was varied between 0° and 8°. The Reynolds number based on the mid-chord length of the wing-section is 140000. The first part of the study consisted of a detailed structural characterization of the winglets at various input excitation and pressure loading conditions. The second part consisted of low speed wind tunnel tests to investigate the effects of actuation on the development of wingtip vortices at different angles of incidence. Measurements included static surface pressure distributions and Stereoscopic (ensemble and phase-locked) Particle Image Velocimetry (SPIV) at various downstream planes. Modal analysis of the fluctuations existing in the baseline vortex and those introduced by actuation is conducted with the help of Proper Orthogonal Decomposition (POD) technique. The winglet oscillations show bi-modal behavior for both structural and actuation modes of resonance. The oscillatory amplitude at these actuation modes increases linearly with the magnitude of excitation. During wind tunnel tests, fluid structure interactions lead to structural vibrations of the wing. The effect of these vibrations on the winglet oscillations decreases with the increase in the strength of actuation. At high input excitation, the actuated winglet is capable of generating controlled oscillations suitable for perturbing the vortex. The vortex associated with a winglet is stretched along its axis with multiple vorticity peaks. The center of the vortex core is seen at the root of the winglet while the highest vorticity levels are observed at the tip. The vortex core rotates and becomes more circular in shape while diffusing downstream. The shape, position, and strength of the vorticity peaks are found to vary periodically with winglet oscillation. Actuation is even capable of disintegrating the single vortex core into two vortices. The most energetic POD fluctuation modes, at the center of the baseline vortex core, correspond to vortex wandering at the initial downstream planes. At the farthest planes, the most energetic modes can be associated with core deformation. High energy fluctuations in the actuated vortex correspond to spatial oscillations and distortions produced by the winglet motion.

Show moreThe objective of this computational study is to examine and quantify the influence of fundamental flow control inputs in suppressing flow separation over a canonical airfoil. Most flow control studies to this date have relied on the development of actuator technology, and described the control input based on specific actuators. Taking advantage of a computational framework, we generalize the inputs to fundamental perturbations without restricting inputs to a particular actuator. Utilizing this viewpoint, generalized control inputs aim to aid in the quantification and support the design of separation control techniques. This study in particular independently introduces wall-normal momentum and angular momentum to the separated flow using swirling jets through model boundary conditions. The response of the flow field and the surface vorticity fluxes to various combinations of actuation inputs are examined in detail. By closely studying different variables, the influence of the wall-normal and angular momentum injections on separated flow is identified. As an example, open-loop control of fully separated, incompressible flow over a NACA 0012 airfoil at α = 6° and $9° with Re = 23,000 is examined with large-eddy simulations. For the shallow angle of attack α = 6°, the small recirculation region is primarily affected by wall-normal momentum injection. For a larger separation region at α = 9°, it is observed that the addition of angular momentum input to wall-normal momentum injection enhances the suppression of flow separation. Reducing the size of the separated flow region significantly impacts the forces, and in particular reduces drag and increases lift on the airfoil. It was found that the influence of flow control on the small recirculation region (α = 6°) can be sufficiently quantified with the traditional coefficient of momentum. At α = 9°, the effects of wall-normal and angular momentum inputs are captured by modifying the standard definition of the coefficient of momentum, which successfully characterizes suppression of separation and lift enhancement. The effect of angular momentum is incorporated into the modified coefficient of momentum by introducing a characteristic swirling jet velocity based on the non-dimensional swirl number. With the modified coefficient of momentum, this single value is able to categorize controlled flows into separated, transitional, and attached flows. With inadequate control input (separated flow regime), lift decreased compared to the baseline flow. Increasing the modified coefficient of momentum, flow transitions from separated to attached and accordingly results in improved aerodynamic forces. Modifying the spanwise spacing, it is shown that the minimum modified coefficient of momentum input required to begin transitioning the flow is dependent on actuator spacing. The growth (or decay) of perturbations can facilitate or inhibit the influence of flow control inputs. Biglobal stability analysis is considered to further analyze the behavior of control inputs on separated flow over a symmetric airfoil. Assuming a spanwise periodic waveform for the perturbations, the eigenvalues and eigenvectors about a base flow are solved to understand the influence of spanwise variation on the development of the flow. Two algorithms are developed and validated to solve for the eigenvalues of the flow: an algebraic eigenvalue solver (matrix based) and a time-stepping algorithm. The matrix based approach is formulated without ever storing the matrices, creating a computationally memory efficient algorithm. Based on the matrix based solver, eigenvalues and eigenvectors are identified for flow over a NACA 0015 airfoil at Re = 200, $600, and $1,000. All three cases contain similar modes, although the growth rate of the leading eigenvalue is decreased with increasing Reynolds number. Three distinct types of modes are found, wake mode, steady mode, and modes of the continuous branch. While this method is limited in the range of Reynolds numbers, these results are used to validate the time-stepper approach. Increasing the Reynolds number to Re = 23,000 over a NACA 0012 airfoil, the time-stepper method is implemented due to rising computational cost of the matrix-based method. Stability analysis about the time-averaged flow is performed for spanwise wavenumbers of β = 1$, $10π, and $20π, which the latter two wavenumbers are representative of the spanwise spacing between the actuators. The largest spanwise wavelength (β = 1$) contained unstable modes that ranged from low to high frequency, and a particular unstable low-frequency mode corresponding to a frequency observed in the lift forces of the baseline large-eddy simulation. For the larger spanwise wavenumbers, β = 10π ($L_z/c = 0.2$) and $20π ($L_z/c = 0.1$), low-frequency modes were damped and only modes with $f > 5$ were unstable. These results help us gain further insight into the influence of the flow control inputs. Flow control is not implemented in a manner to directly excite specific modes, but does dictate the spanwise wavelengths that can be generated. Comparing the unstable eigenmodes at these two spacings, the larger spanwise spacing ($\beta = 10\pi$) had a greater growth rate for the majority of the unstable modes. The smaller spanwise spacing ($\beta = 20\pi$) has only a single unstable mode with a growth rate an order of magnitude smaller than $\beta = 10\pi$. With the aid of the increased growth rate, perturbations to the flow with a wider spacing become more effective by interacting with natural modes of the flow. Taking advantage of these natural modes allows for decreased input for the wider spanwise spacing. In conclusion, it was shown that the influence of wall-normal and angular momentum inputs on fully separated flow can adequately be described by the modified coefficient of momentum. Through further analysis and the development of a biglobal stability solver, spanwise spacing effects observed in the flow control study can be explained. The findings from this study should aid in the development of more intelligently designed flow control strategies and provide guidance in the selection of flow control actuators.

Show moreMuch recent scholarship on metal music has treated the repertoire through historical and ethnomusicological lenses. While the theoretical literature has engaged certain significant artists– particularly Meshuggah and Dream Theater—several important bands and aspects of the music have been overlooked. Especially significant is the relative lack of writing focusing on rhythmic and metric elements of this music which shape a large part of these genres’ distinctive sounds. My goals for this dissertation are twofold. First, this document serves as a style study with regard to rhythm, meter, hypermeter, and phrase rhythm as heard in contemporary metal music (i.e., metal music from around the mid-1990s to the present). Second, I demonstrate how the ways in which contemporary metal artists manipulate rhythm, meter, hypermeter, and phrase rhythm introduce new concepts or extensions of existing modes of analyses. I problematize two metric devices, namely asymmetric meter and metric modulation, as they apply to popular music, demonstrating applications of my conceptual framework to the contemporary metal repertoire. In my analyses, I adapt existing methodologies by Lerdahl and Jackendoff (1983), Temperley (2001), Pearsall (1997), Rothstein (1989), and Krebs (1999), specifically Lerdahl and Jackendoff’s and Temperley’s preference-rule systems, Pearsall’s durational set notation, Rothstein’s descriptions of manipulations of hypermeter and phrase rhythm, and Krebs’s two types of metrical dissonance. Although the sources on which I base aspects of this study deal largely with a different repertoire than mine, the similarities between common-practice Western art music and popular music (including contemporary metal) warrant a similar approach. Where the repertoires diverge—particularly with regard to harmonic syntax and the nuances of metrical dissonance—I suggest alternative methods that address the idiosyncrasies of contemporary metal music. Despite the limited body of works I use for this dissertation, I maintain that the analytical models I propose here are applicable to a wider range of popular music. Therefore, with this document, I contribute to the broader cause of rhythm and meter studies in popular music scholarship.

Show moreOne of the key issues that arises when discussing the long eighteenth century is that of identity: self/individual, and group/national. Whereas recent critical work in both literary studies and historiography has concerned itself with the circumstances surrounding the long eighteenth century's fundamental shifts in conceptions of identity, much of this work overlooks the potential for identity to be relational, rather than either exterior or interior to an individual/group. This dissertation explores the relational nature of identity formation in the long eighteenth century by examining a literary genre and a character that depend upon relational interactions in order to sustain themselves: stage comedies and lawyers. Representative dramatic comedies by writers such as George Farquhar, Richard Cumberland, Thomas Lewis O'Beirne, William Wycherly, Christopher Bullock, Henry Fielding, John O'Keeffe, Colley Cibber, George Colman and David Garrick, and Samuel Foote, offer opportunities to study staged representations of lawyers whose clients' issues essentially become those of identity formation. This dissertation argues that, for many characters struggling to establish an identity that can participate in a national British identity, the key to such participation lies in access to real property; when access to real property is denied them, they must turn to someone who is himself struggling to establish an identity. At this point, lawyers in eighteenth-century British comedies become much more than stock characters or mere comic relief. Instead, the lawyer—often ostracized and derided himself—becomes a mediator not just of individual identity, but of "Britishness." Careful attention to lawyers' success representing different types of clients struggling to establish identities through access to real property highlights both the power of relational identity formation and the key roles that arguably minor characters have in arbitrating issues of national significance.

Show moreHigh-speed impinging jets are often generated by the propulsive systems of aerospace launch vehicles and tactical aircraft. In many instances, the presence of these impinging jets creates a hazard for flight operations personnel due to the extremely high noise levels and unsteady loads produced by fluid-surface interaction. In order to effectively combat these issues, a fundamental understanding of the flow physics and dominant acoustic behavior is essential. There are inherent challenges in performing such investigations, especially with the need to simulate the flowfield under realistic operational conditions (temperature, Mach number, etc.) and in configurations that are relevant to full-scale application. A state-of-the-art high-temperature flow facility at Florida State University has provided a unique opportunity to experimentally investigate the high-speed impinging jet flowfield at application-relevant conditions. Accordingly, this manuscript reports the findings of several experimental studies on high-temperature supersonic impinging jets in multiple configurations. The overall objective of these studies is to characterize the complex relationship between the hydrodynamic and acoustic fields. A fundamental parametric investigation has been performed to document the flowfield and acoustic characteristics of an ideally-expanded supersonic air jet impinging onto a semi-infinite flat plate at ambient and heated jet conditions. The experimental program has been designed to span a widely-applicable geometric parameter space, and as such, an extensive database of the flow and acoustic fields has been developed for impingement distances in the range 1d to 12d, impingement angles in the range 45 degrees to 90 degrees, and jet stagnation temperatures from 289K to 811K (TTR=1.0 to 2.8). Measurements include point-wise mean and unsteady pressure on the impingement surface, time-resolved shadowgraphy of the flowfield, and fully three-dimensional near field acoustics. Aside from detailed documentation of the flow and acoustic fields, this work aims to develop a physical understanding of the noise sources generated by impingement. Correlation techniques are employed to localize and quantify the spatial extent of broadband noise sources in the near-impingement region and to characterize their frequency content. Additionally, discrete impingement tones are documented for normal and oblique incidence angles, and an empirical model of the tone frequencies has been developed using velocity data extracted from time-resolved shadowgraphy together with a simple modification to the conventional feedback formula to account for non-normal incidence. Two application-based studies have also been undertaken. In simulating a vertical take-off and landing aircraft in hover, the first study of a normally-impinging jet outfitted with lift-plate characterizes the flow-acoustic interaction between the high-temperature jet and the underside of an aircraft and documents the effectiveness of an active flow control technique known as `steady microjet injection' to mitigate high noise levels and unsteady phenomena. The second study is a detailed investigation of the jet blast deflector/carrier deck configuration aimed at gaining a better understanding of the noise field generated by a jet operating on a flight deck. The acoustic directionality and spectral characteristics are documented for a model-scale carrier deck with particular focus on locations that are pertinent to flight operations personnel.

Show moreThe leading edge slat of a high-lift system is known to be a large contributor to the overall radiated acoustic field from an aircraft during the approach phase of the flight path. This is due to the unsteady flow field generated in the slat-cove and near the leading edge of the main element. In an effort to understand the characteristics of the flow-induced source mechanisms, a suite of experimental measurements has been performed on a two-dimensional multi-element airfoil, namely, the MD-30P30N. Particle image velocimetry provide mean flow field and turbulence statistics to illustrate the differences associated with a change in angle of attack. Phase-averaged quantities prove shear layer instabilities to be linked to narrowband peaks found in the acoustic spectrum. Unsteady surface pressure are also acquired, displaying strong narrowband peaks and large spanwise coherence at low angles of attack, whereas the spectrum becomes predominately broadband at high angles. Nonlinear frequency interaction is found to occur at low angles of attack, while being negligible at high angles. To localize and quantify the noise sources, phased microphone array measurements are per- formed on the two dimensional high-lift configuration. A Kevlar wall test section is utilized to allow the mean aerodynamic flow field to approach distributions similar to a free-air configuration, while still capable of measuring the far field acoustic signature. However, the inclusion of elastic porous sidewalls alters both aerodynamic and acoustic characteristics. Such effects are considered and accounted for. Integrated spectra from Delay and Sum and DAMAS beamforming effectively suppress background facility noise and additional noise generated at the tunnel wall/airfoil junction. Finally, temporally-resolved estimates of a low-dimensional representation of the velocity vector fields are obtained through the use of proper orthogonal decomposition and spectral linear stochastic estimation. An estimate of the pressure field is then extracted by Poissons equation. From this, Curles analogy projects the time-resolved pressure forces on the airfoil surface to further establish the connection between the dominating unsteady flow structures and the propagated noise.

Show moreThis dissertation both surveys contemporary work in metanormativity and argues for a position that I call moderate normative skepticism. I begin by evaluating efforts to characterize the normative domain and conclude that while some normative concepts and properties are amenable to naturalistic programs of reduction and analysis, other normative concepts and properties are not. I proceed to clarify accounts of reasons, reasoning, and rationality; this establishes argumentative room to maneuver for my moderate normative skepticism. Next, I evaluate moral error theories, which I count as close cousins of my own thesis, and I note how these error theories have more profound implications than their authors realize. I claim that, understood properly, these error theories extend to the domain of normative reasons in general. I accept and defend the extension of error theory as a viable position. In the final chapter of my dissertation, I defend my position against charges of self-defeat and attempt to anticipate and defuse potential criticisms.

Show moreThis analytic dissertation explores tragic and ironic narratives in post-1945 orchestral works through the lens of musical agency and critical theory. For the purposes of this study, I define musical narrative as any sequencing of musical events mediated by agency in which a musical story emerges that underscores the sequence of musical events. My definition and overall methodology for musical narrative follows the work of Lawrence Kramer, Michael Klein, and Byron Almén as I explore tragedy and irony in three large-scale compositions composed after World War II. From Kramer, I break down the narrative process into three components: (1) narrativity, what generates a narrative account; (2) narratography, the discoursing of a narrative; and (3) narrative, the musical story that accompanies the discourse. From Klein (and others), I borrow concepts from intertextuality, critical theory, literary theory, and philosophy to inform these musical stories. Finally, from Almén, I take the tragic narrative archetype as an organizational analytical tool in my analyses. The primary narrativity in each analysis is a form of musical agency, and each analysis questions the role of agency in the interpretation of tragic musical stories in these post-1945 works. For the purposes of this study, musical agency is defined as a perceived entity's ability to interact with its environment, often emerging as personification of musical events. Scholars differ on how agencies interact: whether they have volition and intention, whether they arise as a singular subjectivity, what kind of space they inhabit, etc. While some depict musical agency as a messy endeavor, others aim to provide a structure for its interpretation. As an organizing principle, I use Seth Monahan's four agential classes to focus my discussion. Each chapter generally addresses one of the following: (1) the individuated element (notes, harmonies, themes), (2) the work-persona (the personification of the whole piece), (3) the fictional composer (the being postulated by the analyst as the controlling author of a work), and (4) the analyst. Hence, after an introduction, each of the succeeding chapters of this dissertation focuses on one agential class as a guiding narrativity. I bring narrative and agency together by borrowing ideas from literary theory, psychoanalysis, and philosophy. In chapter two I explore the agential class of the work-persona in Krzysztof Penderecki's Third Symphony, in which the work-persona laments and dies twice, yielding a scenario described by Slavoj Žižek as the "two deaths." In that reading one death is real and the other is symbolic, and the ordering of the deaths in Penderecki's symphony leads the analyst to read the scenario tragically. The two deaths generate the interpretation of death as a master signifier, borrowing from the work of Jacques Lacan. The master signifier then guides the analytical decisions that are made. In my analysis of Thomas Adès's Asyla in chapter three, fictional composer agencies are locked in a power struggle, leading to a reading that evokes Michel Foucault's conceptualizations of power and panopticism. Investigating the individuated element agency in chapter four, I posit that George Rochberg's conservative employment of serial technique in his Symphony No. 2 leads to a reading of belatedness that supplements its commentary on the tragedy of the Second World War. My final chapter serves as an analysis of the analyst, the highest ranking of Monahan's agential classes. Here I describe the three analyses of the preceding chapters as three component parts that contribute to an analyst's machine, following the philosophy of Gilles Deleuze. The analyst's machine serves as a departure point for an exploration of analytical subjectivity. I begin that inquiry by positioning the analyst in a virtual space (as opposed to an actual space). I next parallel Lacan's formulation of the identity with the analytical process, tracing how analysts build their identity through a combination of received components, resulting in a fractured subjectivity. Finally, I bring back the idea of fiction (from the fictional composer agency) to establish a fictional analyst who is a Deleuzian assemblage of refrains and avatars that carries out an analysis. The goal of this dissertation is to uncover narrative approaches to post-1945 music by combining familiar analytical tools with interdisciplinary methodologies. Focusing on a certain agential class as a narrativity, the individual analyses of tragic works by Penderecki, Adès, and Rochberg lead to a reconsideration of the analyst in the concluding chapter—and that chapter serves as a starting point for future analytical and theoretical endeavors.

Show moreThe proportion of individuals aged 65 and over is growing at an astronomical rate in the United States, and some estimate that this demographic age group will double by the year 2025. Aging adults are primarily dependent on the personal automobile as their main source of transportation. Older adults and adults nearing retirement age also tend to reside in suburban neighborhoods and rely heavily on personal vehicles. Since most of the United States is characterized by automobile dependent suburbanization, where the majority of development is suburban low-density sprawl, this may become problematic for aging populations who may be uncomfortable driving longer distances and making more trips. These trends invite the question of whether the deck is stacked against individuals approaching retirement age (50-64) and aging populations (65 and up). This study examines aging populations’ mobility and determines whether they have different travel patterns than their younger cohorts. Additionally, this investigation explores whether or not travel patterns across age groups result in differential access to particular goods and services, as well as differences in travel environment characteristics in a metropolitan area. This research proposes an approach based on Time Geographic Density Estimation (TGDE) to identify activity spaces across different age cohorts in order to identify differences in the mobility and travel behavior of aging adults. TGDE is an established technique in the literature, which blends the notion of activity spaces with the computation of probabilistic potential path trees along a transportation system. In this way it establishes an ‘extent’ or overall mapping of the activity space of an individual, but is able to further refine that extent to identify the most likely places they are able to visit within that geography. Data on origin and destination trips and travel times are taken from the National Household Travel Survey (NHTS) Florida add-on for the study area of Orlando Metropolitan Statistical Area (MSA). Transportation is an important consideration in planning for aging populations, and analyzing differences in how older adults travel compared to their younger counterparts can offer insight into the diverse needs of this group.

Show moreIn the past two decades, the older prisoner population in the U.S. has experienced unprecedented growth (Carson & Sabol, 2016; Scaggs & Bales, 2016). In fact, older prisoners represent the fastest growing inmate population (Carson & Sabol, 2016). This growth has become an important policy concern for government officials and correctional administrators because these prisoners are substantially more expensive to incarcerate and less likely to reoffend compared to younger prisoners (Chettiar et al., 2012). Older prisoners are more fiscally demanding to correctional systems due to healthcare and special housing considerations (Chettiar et al., 2012; Nowotny et al., 2015; Lemieux, Dyeson, & Castiglione, 2002; Linder & Meyers, 2007; Reimer, 2008). Older prisoners also represent a diverse population comprised of different criminal history profiles. While many prisoners are first time servers in old age, others are chronic offenders who have been in and out of prison multiple times (Beckett, Peternelj-Taylor, & Johnson, 2003). However, there is a void in prior literature regarding differences in the in-prison adaptation and post-prison reentry experiences among these inmates based on being a first time server and alternative definitions of what constitutes being an 'older prisoner. The current study seeks to fill two gaps in the prior literature on older prisoners. First, it will assess how older inmates differ from younger inmates in terms of in-prison adjustment and post-prison outcomes. Previous research studies find that older prisoners are less likely to engage in most types of prison misconduct (Blowers & Blevins, 2015) and to reoffend after prison release relative to their younger counterparts (Durose et al., 2014). What is less documented in prior studies is whether the employment prospects for older ex-convicts differ from those among younger prisoners and the extent to which finding work may, in turn, affect recidivism. Second, this study highlights the heterogeneity that exists among older versus younger inmates in their prison adaptation and reentry outcomes based on age and criminal history. A large percentage of older prisoners have never been previously incarcerated in prison. The Florida Department of Corrections 2013-2014 Annual Report shows that 46.2 percent of prisoners age 50 or older were committed to prison for the first time (Florida Department of Corrections, 2014). Prior research suggests that first time older prisoners may have an especially adverse response, and ultimately adjustment, to their commitment to prison which is manifested through institutional rule violations in the presence of family conflict, suicidal thoughts, depression, and fear of death (Aday, 1994; Leigey, 2015). This study uses data from a release cohort of former prisoners in Florida from 2004 to 2011 to examine differences between younger versus older prisoners. The data include institutional measures, pre-prison employment and criminal histories, and post-prison employment and recidivism information to examine differences in prison adjustment and post-release outcomes among different age groups and being a first time server among older versus younger inmates. By examining the effects of alternative age definitions on three primary outcomes—(1) prison misconduct, (2) post-prison employment, and (3) recidivism—this study contributes to prior literatures on gerontology, prison management, age stratification of post-prison employment opportunities, and recidivism. This study's focus on using old age as a key variable for explaining in-prison and reentry process outcomes is pertinent to a broader study of gerontology because it addresses important issues faced by a special subset of older adults within society. This study also contributes to the current literature on crime over the life course by assessing if and when older inmates are likely to find short-term employment and recidivate.

The algorithms use modular reduction, Hensel lifting, rational function reconstruction, and rational number reconstruction to do so. Numerous examples from different branches of science (mostly from combinatorics and physics) showed that the algorithms presented in this thesis are very effective. Presently, Algorithm 5.2.1 is the most general algorithm in the literature to find hypergeometric solutions of such operators. This thesis also introduces a fast algorithm (Algorithm 4.2.3) to find integral bases for arbitrary order regular singular differential operators with rational function or polynomial coefficients. A normalized (Algorithm 4.3.1) integral basis for a differential operator provides us transformations that convert the differential operator to its standard forms (Algorithm 5.1.1) which are easier to solve.

While there are maize proteins with similar domains as known remodelers, the ability of the maize proteins to alter nucleosome position has not been reported. Mutant alleles of genes encoding several maize proteins (RMR1, CHR101, CHR106, CHR127, CHR156, CHB102, and CHR120) with similar functional domains to known chromatin remodelers were identified. Altered expression of Chr101, Chr106, Chr127, Chr156, Chb102, and Chr120 was demonstrated in plants homozygous for the mutant alleles. These mutant genotypes were subjected to nucleosome position analysis to determine if misregulation of putative maize chromatin proteins would lead to altered DNA-histone interactions. Nucleosome position changes were observed in plants homozygous for chr101, chr106, chr127, chr156, chb102, and chr120 mutant alleles, suggesting that CHR101, CHR106, CHR127, CHR156, CHB102, and CHR120 may affect chromatin structure. The role of RNA polymerases in altering DNA-histone interactions was also tested. Changes in nucleosome position were demonstrated in homozygous mop2-1 individuals. These changes were demonstrated at the b1 tandem repeats and at newly identified loci. While the α-amanitin-inhibited RNA polymerase II demonstrated reduced expression of an RNA polymerase II transcribed gene, no changes in nucleosome position were detected in the α-amanitin-treated plants. Additionally, differential DNA-histone interactions and altered expression of putative chromatin remodelers in different maize haplotypes suggest a role for differentially expressed chromatin proteins in haplotype-specific variation.

Show moreNational recommendations for undergraduate biology education call for orchestrating opportunities for students to "figure out" scientific explanations in the classroom setting by engaging in similar disciplinary practices and discourses as scientists. One approach to realize this vision, ambitious science teaching, describes four essential practices, each of which emphasizes classroom talk as an essential feature of student understanding. However, a critical element of reform is the instructor, who translates and enacts recommended practices in the classroom. This dissertation examines three specific aspects of ambitious science teaching in the context of an undergraduate biology laboratory course: how teaching assistants (TAs) take up the ambitious science teaching practice of eliciting and responding to student ideas, how TAs use positioning acts to support or constrain students' opportunities to engage in rigorous scientific discourse, and how engaging students in ambitious science teaching practices is mutually supportive for both the TAs develop as a professional scientist and the students' development of proficiency in science. The first study described how thirteen undergraduate biology TAs enacted one ambitious practice, eliciting and responding to students' initial and unfolding ideas, in a general biology laboratory course for nonscience majors before and after one semester of targeted professional development. Each participant was videotaped teaching the same lesson at the beginning of his or her first and second semesters as a TA. These videos were transcribed and coded for ambitious and conservative discursive moves. The findings describe four common profiles for how TAs changed in their practice of eliciting and responding to student ideas after one semester, with one profile eliciting more rigorous student discourse, one profile eliciting less rigorous student discourse, and two profiles fall in the middle of the spectrum. Implications for TA professional development are discussed. The next study was based on the premise that classrooms are complex systems, with a variety of factors influencing the teaching and learning that takes place within the system, including how teachers enact instructional practices. Teachers may translate and enact the same instructional practice differently, which could have important consequences for student learning opportunities. This study examined TA views about the role of the TA and the role of the students in classroom conversations and how these views supported or constrained opportunities for students to engage in scientific discourse. Using qualitative case study methodology, I examined how five TAs enacted whole class conversations in four different lab investigations over two different semesters. Using positioning acts as an analytical lens, the data were analyzed to develop themes describing how the role of the TA and the students was signaled in these five classrooms. The findings illustrated how TAs who positioned students as critical contributors to scientific conversations created opportunities for students to engage in scientific discourse while TAs who self-positioned as the authority on biology knowledge limited opportunities for students to engage in scientific discourse. Implications for classroom practice are discussed. The final study is based on the premise that, due to the calls for reforming undergraduate biology education, biology TAs are increasingly responsible for enacting student-centered instruction. However, TAs must balance coursework, research and teaching responsibilities, and teaching responsibilities are seldom considered opportunities to develop biology expertise needed as a professional scientist. However, some evidence suggests that using ambitious science teaching practices that engage students in the practices and discourses of science actually supports the TA in developing scientific expertise. This research investigated this link by examining how TAs organize biological knowledge before and after teaching a general biology lab curriculum that supported ambitious pedagogy. It also examined the relationship between knowledge organization and instructional practices. To capture changes in TA's knowledge organization, they completed a card-sorting task at the start and end of the semester. To capture instructional practices, TAs were videotaped teaching the same lab at the beginning of two consecutive semesters. The conversations in these teaching episodes were transcribed and TA talk was coded for ambitious discourse moves. TA knowledge organization was significantly more sophisticated after one semester of teaching experience. The sophistication of TA's knowledge organization was also positively related to their use of ambitious discourse moves to elicit and respond to student contributions. This relationship suggests a mutually supportive connection between ambitious teaching practice and disciplinary expertise. Implications for TA professional development are discussed.

Show moreAnxiety sensitivity (AS) has become one of the most well researched risk factors for the development of psychopathology. Research has found that the AS subfactor of cognitive concerns may play an important role in PTSD, depression, and suicide. AS reduction protocols commonly use interoceptive exposure (IE), or exposure to bodily sensations, to reduce AS. However, current IE paradigms (e.g., CO2 inhalation, straw breathing, hyperventilation) primarily induce physical anxiety symptoms (e.g., racing heart, dizziness), and thus might not be optimal for the reduction of AS cognitive concerns. Previous work has shown that fear reactivity during the induction of dissociative symptoms is uniquely associated with AS cognitive concerns, and therefore it is possible that repeated exposure to dissociative symptoms will result in habituation and decreased AS cognitive concerns. The current study investigated whether repeated exposure to the induction of dissociative symptoms would reduce AS cognitive concerns, and thus be viable as an IE component of treatments directly targeting AS cognitive concerns. Participants (N = 50) who scored at or above 1 SD above the mean on the ASI-3 cognitive subscale were randomly assigned to repeated exposure to dissociative symptoms through audio-visual stimulation or to a control condition (repeatedly listening to classical music). Results revealed that the classical music control condition resulted in significant decreases in AS cognitive concerns as compared the active dissociation exposure treatment. Unfortunately, these results do not support the viability of this exposure paradigm in the current format as a treatment for elevated AS cognitive concerns. Future directions include increasing the potency of the symptoms induced, increasing the number of exposures, and providing a stronger conceptual framework for the participants prior to undergoing the exposures.

Title: Amy Beach's Cabildo: An American Opera.
Creator: Powlison, Nicole M. (Nicole Marie), Seaton, Douglass, Fisher, Douglas L., Eyerly, Sarah, Pelkey, Stanley C., Florida State University, College of Music
Abstract/Description: In June 1932 Amy Beach (1867–1944) arrived at her studio at the MacDowell Colony in Peterborough, New Hampshire, to begin working in one of the few major musical genres that she had yet to attempt in her career: an opera, called Cabildo. The libretto for the chamber opera, given to her by Atlanta author, playwright, and fellow Colonist Nan Bagby Stephens (1883–1946), was based on Stephens's own play with the same title.

Show moreIn June 1932 Amy Beach (1867–1944) arrived at her studio at the MacDowell Colony in Peterborough, New Hampshire, to begin working in one of the few major musical genres that she had yet to attempt in her career: an opera, called Cabildo. The libretto for the chamber opera, given to her by Atlanta author, playwright, and fellow Colonist Nan Bagby Stephens (1883–1946), was based on Stephens's own play with the same title. Cabildo's creators had to negotiate the multifaceted artistic expression of American identity through the work's music and plot. The English libretto, rich with local color in sections of dialect, was blended with the sounds of Creole folk tunes and Beach's own art songs to spin a romantic tale of dashing pirates and ghostly lovers, set during the height of the Battle of New Orleans, the final conflict of the War of 1812. Well received at its modest premiere at the University of Georgia in 1945, Beach's only opera remains unpublished and rarely studied or performed. A primary component of this project is the critical edition of Amy Beach's only opera, Cabildo, op. 149, completed in 1932. This edition is prepared to professional publication standards and provides a resource for both scholarly study and performance. The original draft and performance manuscripts of the score from archives at the University of New Hampshire and the University of Missouri-Kansas City provide the source material for the edition. In addition to the critical edition, the dissertation provides a "thick description" of Cabildo that locates the opera in its historical context. Relying on primary source materials such as Beach's diaries and newspaper or magazine articles, this description places the work in the composer's life as a new type of project that comes at the very end of her career, and an opportunity to collaborate with another woman. The description also identifies musical works with contemporary themes or methods to draw comparisons between Cabildo and its contemporaries, placing it in the context of the varied styles of American English-language opera in the 1930s. Cabildo represents one way in which a particular American opera expresses national identity through music and plot. Composers such as Beach attempted to negotiate the aesthetic conundrum that demanded that American art music be of the highest cosmopolitan standards while still having something distinctly "American" about it. This was complicated by the desire of many composers to incorporate American musics that lay outside the European musical heritage, including the simultaneously local and exotic musical materials from African American and Native American cultures. Cabildo exemplifies this complex negotiation of American identity in opera: it is an American opera with a libretto in English, treating a historical topic important to the history of the United States, yet incorporating a mix of Creole folk songs and dialect with music in Beach's own style, all set in the exotic location of New Orleans. By uniting a significant event from national history with a distinctive regional music set in a familiar Romantic style, Beach and Stephens created an opera that is at once intrinsically American and still appealing to a diverse and cosmopolitan audience.

Show moreOsteosarcopenic obesity (OSO) is a recently identified geriatric syndrome characterized by simultaneous presence of osteopenia/osteoporosis, sarcopenia, and increased adiposity either as overt overweight or fat infiltration into bone and muscle. The diagnostic criteria for OSO are just being established, but there are no data on biomarkers that might characterize this syndrome. Our objective was to examine possible biomarkers associated with OSO syndrome, including serum sclerostin (as a hinder of bone formation), skeletal muscle-specific troponin T (sTnT) (as an indicator of muscle turnover/damage) and serum leptin and adiponectin (measurement for fat metabolism). Additionally, we analyzed C-reactive protein (CRP) and serum lipids to evaluate the level of inflammation and lipid profile, respectively. A total of n=59 healthy Caucasian women ≥65 years were classified into 4 groups based on their bone and body composition profile identified by Dual-energy X-ray Absorptiometry (DXA) measurements: 1) Osteopenic obese (N=35); 2) Obese-only (N=10); 3) OSO (N=10); 4) Osteopenic/sarcopenic non-obese (N=4). Osteopenia/osteoporosis was determined by T-score of L1-L4 and/or femoral neck≤-1. Appendicular lean mass adjusted for both height and fat mass. Appendicular lean mass residual value of ≤ -1.43 was used as the cut-off point for diagnosing sarcopenia. Obesity included women with body fat percentage ≥32%. Serum samples were analyzed using ELISA kits for sclerostin, sTnT, leptin and adiponectin. CRP and Lipid profile were analyzed at Tallahassee Memorial Hospital using the latex amino assay and lipoprotein assay, respectively. In addition, diet and habitual physical activity were evaluated by 3-day dietary record and the Allied Dunbar National Fitness Survey, respectively. Data were evaluated by Pearson's correlations and ANOVA followed by Tukey's tests with p≤0.05. Serum sclerostin was significantly higher in OSO and osteopenic obese group in comparison to the obese-only group. The sTnT concentrations were significantly higher in OSO group in comparison to osteopenic obese and obese-only group. Sclerostin was negatively correlated with bone mineral density/content (BMD/BMC) of all skeletal sites, and the relationship was statistically significant with femoral neck BMD/BMC. Moreover, there was a significant positive correlation between serum sclerostin and sTnT, indicating their simultaneous mediation in bone and muscle loss. The highest concentrations of serum leptin were observed among OSO group. Women in OSO group had significantly greater leptin concentration than osteopenic/sarcopenic non-obese group. Serum leptin was significantly negatively correlated with left femoral neck BMD and T-score, total BMC and left femur BMC after adjusting for weight or BMI. Statistically significant negative correlation of serum adiponectin with body fat percentage was noted, as well as with the BMD and T-scores of several skeletal sites, including total femur and femoral neck. The osteopenic/sarcopenic non-obese group had the highest level of adiponectin (µg/mL) in comparison to other groups. These results confirm the negative relationship between adiposity and serum adiponectin. Significant negative correlation between serum leptin and BMD in groups with increased body fat may indicate its mediating role between bone and body adiposity. The CRP concentrations for all participants ranged from 0.01 to 1.43 mg/dL. None of the CRP concentrations were above the high threshold (3.0 mg/dL). Although the highest concentrations of CRP were observed among OSO group, there was no significant difference between groups. The highest concentrations of cholesterol and low density lipoprotein (LDL) were observed in the OSO group. Moreover, the highest concentrations of triglyceride were observed among the osteopenic obese group vs lowest for osteopenic/sarcopenic non-obese group. Although, the lowest amount of energy intake was observed among OSO group, there was no significant difference among groups. Moreover, there was no significant difference in amount of vitamin D and calcium intake among the groups. The lowest amount of protein intake was observed in the OSO group; however, there was no significant difference among groups. There was a significant positive correlation between total calcium intake and lean/fat ratio. Moreover, there was a significant negative correlation between amount of protein intake and waist/hip ratio. In conclusion, women identified with OSO syndrome have presented with the poorest outcomes for each variable. The combination of high concentration of sclerostin, sTnT, leptin and low adiponectin can be used to better identify the metabolic profile of OSO syndrome and possibly apply as measurements for its diagnostic criteria.

Show moreThis dissertation research uses the analysis of internet-based comments on two major news stories to study the role of identity in anchoring power during discursive participation. For this purpose, identity includes the categorical group memberships that people may place themselves or others into, such as gender, race, or occupation. Identity, as an anchor, is used as a resource for the purpose of linking one’s wishes to power, with power being the amount of preferential treatment given to any particular identity in determining the course of events or proper direction of discussion. The Daniela Pelaez case and Trayvon Martin case were each selected for making national headlines at approximately the same time, both occurring in the same state, and both being in reference life altering circumstances for minority teenagers, yet representing different outcomes. A content analysis of news comment board posts for the Daniela Pelaez and Trayvon Martin cases has been performed to ascertain the use of identity in comments and prevalence of particular identities, the use of identity to anchor power, the acknowledgement of identities by readers, and the conditions under which identities were used. One article for each case was selected from the same national news source, with an analysis completed for the first 1,000 comments on each article. Identity used as an anchor to power is found to exist, but only has a significant interaction with presentation of an argument for the Martin case. This indicates that the association between anchoring identity and presenting an argument can vary by news story. Identity as an anchor itself varies with race, and is dependent on how race relates to the news story. It is also found that anchoring is more dependent on authors’ expectations of what others will consider important than it is effective on readers’ actual recordable reactions.

Show moreThe sixteenth and seventeenth centuries saw the rise of an intense interest in Anglo-Saxon history and artifacts that accompanied the transcription, translation, and dissemintation of the contents of England's monastic libraries following the Reformation begun in the 1530s. The tide of religious reform turned to more secular, legal concerns under the two early Stuart kings, and the pre-Norman past was used to simultaneously legitimize and criticize early-seventeenth-century monarchy and its ancient privileges by free monarchists and constitutionalists, respectively. Much of the modern criticism surrounding the constitutional crises of the reigns of James VI and I and Charles I as it relates to the Anglo-Saxon past focuses on Bede and the Benedictine Reformers of the tenth century. The present study, however, considers an often-cited text typically relegated to the periphery: The Anglo-Saxon Chronicle. The Chronicle makes its debut in print under the direction of Abraham Wheelock and the Cambridge University Press in 1643. The annalistic history appears alongside Bede's Historia Ecclesisatica, and, in the 1644 reprint and augmentation, the laws from Ine to Alfred and the later Anglo-Norman kings. Wheelock's editio princeps of the Anglo-Saxon Chronicle appears at the height of the First English Civil War in 1643, and it is often treated by modern critics as an appendix to the Old English Historia to which it is attached. This dissertation argues that the Chronicle is not peripheral, and that it participates in a larger royalist campaign to establish the West Saxons as the institutional forbears of the first two Stuart kings. The opening chapters establish Wheelock and his literary circle as participants in the ongoing constitutional debate that culminated in the Personal Rule of Charles in 1629 and the opening years of the Civil Wars a decade later. After the political alleigances of those who surround the production of the 1643 Chronicle have been thoroughly considered, the focus of this study then turns to the text of the Chronicle itself. Wheelock inserts himself into the Chronicle's narrative by means of excision, substitution, and inconsistent translation so that the Chronicle may more easily conform to early modern perceptions of kingship. Specifically, his intervention into and manipulation of the genealogical West Saxon Regnal Table and his interpretation of the advisory body of the Anglo-Saxons known as the witan provide a lens through which to read the medieval Chronicle as a polticial document suitable for seventeenth-century purposes. Lastly, this dissertation traces the influences of the 1643 edition upon the only other Chronicle printed in that century—the 1692 version compiled and edited by Bishop Edmund Gibson. This final chapter argues that Gibson, like Wheelock, uses the Chronicle for political, and in the latter antiquary's case, nationalistic ends.

Show moreCarbon-carbon bond formation is the foundation to synthesizing complex molecules and has gathered the attention of many synthetic chemists. One must keep in mind that these reactions are dependent on materials for a specific agenda when tackling a structural framework, which may require additional steps to create, and at times, are difficult to prepare. As significant as C-C bond formation reactions are, these minor setbacks may draw caution when synthesizing a complicated molecule whose structural framework cannot be easily accessed by the unity of two fragments. On the other hand, the less familiar C-C bond cleavage reactions have, over time, demonstrated the potential to generate unique structural building blocks that can be used to overcome certain obstacles that other synthetic methods cannot provide. Here, we will be focusing on concerted anionic five-center fragmentation reactions using vinylogous acyl triflates. The generated alkynogenic fragments will then be used in different applications. We will begin by looking at chemoselective “click” reactions. The strained-promoted alkyne is synthesized by a tandem intramolecular nucleophilic addition / fragmentation. The expanded ring will contain a strained cycloalkyne which will later be tethered to a terminal alkyne. The diyne will be used to provide an example of a “dual-click” coupling via SPAAC or CuAAC in either sequential order. Next, we will expand the tandem fragmentation / olefination methodology developed in this work to include dienynes. The dienyne provides the structural backbone needed to produce neopentylene indanes. This methodology is used to design new ibuprofen derivatives that demonstrate rigidity and increase hydrophobicity to modulate the molecular pharmacology of ibuprofen.

We work with the category of holomorphic bundles on a noncommutative torus, which is known to be equivalent to the heart of a nonstandard t-structure on coherent sheaves of an elliptic curve.

Show moreIn this dissertation, we study three important cases in noncommutative geometry. We first observe the standard noncommutative object, noncommutative torus, in noncommutative motives. We work with the category of holomorphic bundles on a noncommutative torus, which is known to be equivalent to the heart of a nonstandard t-structure on coherent sheaves of an elliptic curve. We then introduce a notion of (weak) t-structure in dg categories. By lifting the nonstandard t-structure to the t-structure that we defined, we find a way of seeing a noncommutative torus in noncommutative motives. By applying the t-structure to a noncommutative torus and describing the cyclic homology of the category of holomorphic bundle on the noncommutative torus, we finally show that the periodic cyclic homology functor induces a decomposition of the motivic Galois group of the Tannakian category generated by the associated auxiliary elliptic curve. In the second case, we generalize the results of Laca, Larsen, and Neshveyev on the GL2-Connes-Marcolli system to the GLn-Connes-Marcolli systems. We introduce and define the GLn-Connes-Marcolli systems and discuss the existence and uniqueness questions of the KMS equilibrium states. Using the ergodicity argument and Hecke pair calculation, we classify the KMS states at different inverse temperatures β. Specifically, we show that in the range of n − 1 < β ≤ n, there exists only one KMS state. We prove that there are no KMS states when β < n − 1 and β ̸= 0, 1, . . . , n − 1,, while we actually construct KMS states for integer values of β in 1 ≤ β ≤ n − 1. For β > n, we characterize the extremal KMS states. In the third case, we push the previous results to more abstract settings. We mainly study the connected Shimura dynamical systems. We give the definition of the essential and superficial KMS states. We further develop a set of arithmetic tools to generalize the results in the previous case. We then prove the uniqueness of the essential KMS states and show the existence of the essential KMS stats for high inverse temperatures.

A curriculum was developed focusing on educational social justice theories and their application in regard to gender inequity and diversity issues. The goal was to lead students to engage in more self-directed learning and to become more pro-active in their society. The results indicate the value of using art making to help students explore, investigate, and examine self and self in relation to society. In addition, they shed light on transformational moments in the art making process when students’ awareness of self and social justice issues was heightened and democratic ideas were reinforced. The results have implications for classroom practice as well as enhancing the quality of art education by incorporating social justice concerns in art education for individual and community developments.

Show moreAlthough later medieval St. Albans Abbey has long been renowned as a preeminent center for the writing of historical chronicles, previous studies have not acknowledged that the monastic community also had a sustained tradition of visually representing the house’s institutional history. This dissertation demonstrates that between the late eleventh and early sixteenth centuries, the monks of St. Albans depicted and evoked their abbey’s past in a large and diverse collection of artworks, ranging from illuminated manuscripts and pilgrim badges to monumental paintings and architecture. Monastic historical imagery was rarely produced during the Middle Ages, but the images and objects from St. Albans present a remarkably rich and complete account of the abbey’s history from the time of its illustrious origins through the eve of its dissolution. Using an interdisciplinary approach to contextualize these artworks within the monastery’s history and traditions, this study argues that the visual historiography of St. Albans served as a potent vehicle for the expression and self-fashioning of the abbey’s corporate identity and historical memory. As will be demonstrated, this vast corpus of imagery focuses on three fundamental elements of the monastery’s past: Saint Alban and his early cult, the eighth-century foundation of the monastery by King Offa of Mercia, and the house’s post-foundation history. Through these artworks, many of which have not previously received the attention of art historians, the monks of St. Albans documented, celebrated, and occasionally manipulated their abbey’s long and distinguished history, thereby providing a compelling justification for its continued prosperity and prestige.

Abstract/Description: Understanding athlete transition is a complex process which involves many subjective pieces. A review of previous literature on athletic career termination has shown that two of the most highly debated topics include athletes' specific reason for retirement (Cockerill 2004; Orlick & Sinclair 1993; Webb, Nasco, Riley, & Headrick 1998), and the coping techniques employed by athletes during their transition period (Coakley 1983; Grove, Lavallee, & Gordon, 1997; Lavallee 2005; Sinclair & Orlick,...
Show moreUnderstanding athlete transition is a complex process which involves many subjective pieces. A review of previous literature on athletic career termination has shown that two of the most highly debated topics include athletes' specific reason for retirement (Cockerill 2004; Orlick & Sinclair 1993; Webb, Nasco, Riley, & Headrick 1998), and the coping techniques employed by athletes during their transition period (Coakley 1983; Grove, Lavallee, & Gordon, 1997; Lavallee 2005; Sinclair & Orlick, 1993; Reynolds 1981). The purpose of this study was to examine important components involved in retirement from National Collegiate Athletic Association (NCAA) competitive athletics: self-concept clarity, athletic identity, willingness to retire, coping and overall life satisfaction. Self-concept clarity was conceptualized as the primary variable of focus because it tends to be internally consistent over time (Lodi-Smith & Roberts, 2010), and previous studies have shown that the effect of role exits and entries negatively predicts one's perceived self-concept clarity (Light & Visser, 2013). Participants were female (n=148) and male (n=89) former NCAA athletes from over 75 different Division I colleges and universities across the United States, ranging in age from 20 to 27 years old (M=22.47, SD=.837). They were to be no more than 12 months removed from their last NCAA game or practice, and the total number of months they were retired ranged from 1 to 12 months (M=7.77, SD= 2.1). Path analyses were used to determine which factors significantly contributed to self-concept clarity, and overall life satisfaction. Results revealed coping style, significantly mediated the relationship between athletic identity, willingness to retire, and self-concept clarity. Most importantly, emotion-focused coping lead to higher self-concept clarity for athletes during the transition process, and avoidance coping lead to a negative effect on athlete self-concept clarity.

Show moreIt is advantageous for one seeking a career in trombone, as a performer, and as an educator, to have an in-depth understanding of the trombone avant-garde solo works. For other classical instruments, repertoire spans many centuries and can be found in every major musical era. However, the trombone was a later addition to the orchestra, and it was not seen as a solo instrument until later still. With the development of trombone literature falling predominately in the second half of the 20th century, it is no surprise that the musical avant-garde movement of post-World War II Western society included works for solo trombone. It is important to perform and understand the historical significance of these works since they are certainly worthy of performance. They also are responsible, in part, for the flourishing importance of the trombone as a prominent solo instrument in the twenty-first century. For both of these lecture recitals, there are many great resources to help one understand the historical context and theoretical designs of all of the works I have examined. Stuart Dempster's work as a performer and researcher has proven to be an incredibly valuable source of information for all aspiring trombonists. His book, The Modern Trombone: A Definition of Its Idioms, serves as a major source of inspiration and knowledge for both the understanding and practical approach to performing many of the avant-garde trombone works. Austin Duke's dissertation, A Performer's Guide to Theatrical Elements in Selected Trombone Literature, also serves as a valuable resource regarding the theatrics involved in many of the pieces that will be examined. This performative side of the avant-garde literature is often overlooked, and therefore it is vital to the success of a lecture series on this topic.

Title: Barnburner.
Creator: Hoover, Erin, Belieu, Erin, Nudd, Donna M., Epstein, Andrew, Kimbrell, James, Florida State University, College of Arts and Sciences, Department of English
Abstract/Description: There is no namesake figure in the dissertation manuscript, Barnburner, and no single "Barnburner" poem appears. Instead, the poems reflect a specific modern mindset. The concept "barnburner" was popularized in the mid-nineteenth century as the name of a faction of anti-corporate and anti-slavery New York State Democrats eager for radical reform, their desire for change-at-all-costs apparently alluding to the legend of the old Dutchman who would burn down his barn to rid it of an infestation...
Show moreThere is no namesake figure in the dissertation manuscript, Barnburner, and no single "Barnburner" poem appears. Instead, the poems reflect a specific modern mindset. The concept "barnburner" was popularized in the mid-nineteenth century as the name of a faction of anti-corporate and anti-slavery New York State Democrats eager for radical reform, their desire for change-at-all-costs apparently alluding to the legend of the old Dutchman who would burn down his barn to rid it of an infestation of rats. Although not used widely in the contemporary context, I argue that "barnburner" in its traditional usage describes a discursive mode that has become widespread in the twenty-first century, in which political and personal commitment is understood as belonging to the person or entity willing to risk it all. Though written before the 2016 U.S. election, many of the poems in Barnburner address some of the themes that have emerged, including the complication of intersectional identities of class, race, region, and gender; the disconnection many Americans feel from their labor; and the ephemeral nature of "truth" in digital realities. This is an explicitly political book, and one that recommits to the first-person narrative. In many ways an extension of the project of the confessional poets, the poems of Barnburner connect the figures of history—understood as both personal and collective—to the workings of an emotional inner life, and represent a "re-visioning" of experience bound to social, economic, and political realities.

Show moreAs we routinely encounter high-throughput datasets in complex biological and environment research, developing novel models and methods for variable selection has received widespread attention. In this dissertation, we addressed a few key challenges in Bayesian modeling and variable selection for high-dimensional data with complex spatial structures. a) Most Bayesian variable selection methods are restricted to mixture priors having separate components for characterizing the signal and the noise. However, such priors encounter computational issues in high dimensions. This has motivated continuous shrinkage priors, resembling the two-component priors facilitating computation and interpretability. While such priors are widely used for estimating high-dimensional sparse vectors, selecting a subset of variables remains a daunting task. b) Spatial/spatial-temporal data sets with complex structures are nowadays commonly encountered in various scientific research fields ranging from atmospheric sciences, forestry, environmental science, biological science, and social science. Selecting important spatial variables that have significant influences on occurrences of events is undoubtedly necessary and essential for providing insights to researchers. Self-excitation, which is a feature that occurrence of an event increases the likelihood of more occurrences of the same type of events nearby in time and space, can be found in many natural/social events. Research on modeling data with self-excitation feature has increasingly drawn interests recently. However, existing literature on self-exciting models with inclusion of high-dimensional spatial covariates is still underdeveloped. c) Gaussian Process is among the most powerful model frames for spatial data. Its major bottleneck is the computational complexity which stems from inversion of dense matrices associated with a Gaussian process covariance. Hierarchical divide-conquer Gaussian Process models have been investigated for ultra large data sets. However, computation associated with scaling the distributing computing algorithm to handle a large number of sub-groups poses a serious bottleneck. In chapter 2 of this dissertation, we propose a general approach for variable selection with shrinkage priors. The presence of very few tuning parameters makes our method attractive in comparison to ad hoc thresholding approaches. The applicability of the approach is not limited to continuous shrinkage priors, but can be used along with any shrinkage prior. Theoretical properties for near-collinear design matrices are investigated and the method is shown to have good performance in a wide range of synthetic data examples and in a real data example on selecting genes affecting survival due to lymphoma. In Chapter 3 of this dissertation, we propose a new self-exciting model that allows the inclusion of spatial covariates. We develop algorithms which are effective in obtaining accurate estimation and variable selection results in a variety of synthetic data examples. Our proposed model is applied on Chicago crime data where the influence of various spatial features is investigated. In Chapter 4, we focus on a hierarchical Gaussian Process regression model for ultra-high dimensional spatial datasets. By evaluating the latent Gaussian process on a regular grid, we propose an efficient computational algorithm through circulant embedding. The latent Gaussian process borrows information across multiple sub-groups, thereby obtaining a more accurate prediction. The hierarchical model and our proposed algorithm are studied through simulation examples.

Title: Bayesian Models for Capturing Heterogeneity in Discrete Data.

Show morePopulation heterogeneity exists frequently in discrete data. Many Bayesian models perform reasonably well in capturing this subpopulation structure. Typically, the Dirichlet process mixture model (DPMM) and a variable dimensional alternative that we refer to as the mixture of finite mixtures (MFM) model are used, as they both have natural byproducts of clustering derived from Polya urn schemes. The first part of this dissertation focuses on a model for the association between a binary response and binary predictors. The model incorporates Boolean combinations of predictors, called logic trees, as parameters arising from a DPMM or MFM. Joint modeling is proposed to solve the identifiability issue that arises when using a mixture model for a binary response. Different MCMC algorithms are introduced and compared for fitting these models. The second part of this dissertation is the application of the mixture of finite mixtures model to community detection problems. Here, the communities are analogous to the clusters in the earlier work. A probabilistic framework that allows simultaneous estimation of the number of clusters and the cluster configuration is proposed. We prove clustering consistency in this setting. We also illustrate the performance of these methods with simulation studies and discuss applications.

Show moreUnlike many of the current statistical models focusing on highly skewed longitudinal data, we present a novel model accommodating a skewed error distribution, partial linear median regression function, nonparametric wavelet expansion, and serial observations on the same unit. Parameters are estimated via a semiparametric Bayesian procedure using an appropriate Dirichlet process mixture prior for the skewed error distribution. We use a hierarchical mixture model as the prior for the wavelet coefficients. For the "vanishing" coefficients, the model includes a level dependent prior probability mass at zero. This practice implements wavelet coefficient thresholding as a Bayesian Rule. Practical advantages of our method are illustrated through a simulation study and via analysis of a cardiotoxicity study of children of HIV infected mother.

Show morePerceiving our world is an active process. We actively explore and investigate the environment rather than passively registering the objects and events we encounter. Our perception and attention reflect our moods, expectations, and beliefs. Recent evidence supporting this approach comes from studies that focus on the impact of individual differences on human perception and attention. Characteristics about the world we live in, like culture or religion, may drive these differences in perception and attention. One of the ways this has been looked at is by examining executive functioning. Inhibitory control, the ignoring of irrelevant information, is an important component of executive functioning. The Simon, Flanker, and Stroop tasks are all common measures of inhibitory control. They all require to some degree the inhibition of irrelevant information when selecting an appropriate response to stimuli. Several studies have reported a bilingual advantage on these tasks. Previous research has indicated differences in cognitive functioning for those of different political beliefs. Differences are seen in perception of multi-level stimuli in people of different cultures and religions and for people with different political leanings. Previous research has found similar differences in performance on a measure of executive functioning for people of different religions. The expected effects for the Simon and Flanker task were found in this sample. Differences in the size of the Simon and Flanker effect were not found in this sample for those of different religious beliefs or political beliefs

Show moreThe aeolian transport of aerosols (mineral dust from desert areas, smoke and ash from biomass burning, and from anthropogenic emissions) is an important process for introducing bioactive trace elements to the surface ocean and can have a large impact on marine primary production. All material that enters the ocean from the atmosphere must pass through the air-sea interface, or sea surface microlayer. The microlayer is the physical link between the sea surface and lower atmosphere and is therefore tied to the global biogeochemical cycling of trace elements. The microlayer (50 – 200 µm thickness) is a unique environment with different physical, chemical, and biological properties compared to the underlying water column. The microlayer is dynamic in nature due to numerous non-equilibrium processes such as temperature fluctuations, salinity gradients, irradiance, and wind and wave actions that influence its biogeochemical properties. However, the microlayer is mechanically more stable than the underlying water column due to the higher concentration of surface-active organic compounds; creating a more rigid film-like layer over the surface of the ocean. It is an important, yet often ignored component in the biogeochemical cycling of trace elements in the marine environment due to the lack of trace element clean sampling and analysis methods. A novel technique, a hollow cylinder of ultra-pure SiO₂ (quartz glass) with a plastic handle, was developed to sample the microlayer for trace elements. This research also developed and optimized clean trace element techniques to accurately measure nine trace metals (Al, Mn, Fe, Co, Ni, Cu, Zn, Cd, and Pb) in the dissolved and particulate fractions of the microlayer and underlying water column. Initially, our research focused on the behavior of dissolved and particulate Al, Mn, Fe, Co, Cu, Zn, Cd, and Pb in the microlayer in a controlled tank experiment using a Saharan dust source. The residence times of the dissolved trace elements ranged from 1.8 hours for Fe to 15 hours for Cd. The residence times for the particulate trace elements ranged from 1.0 minutes for Al and Fe to 1.4 minutes for Mn. There was an initial release of dissolved trace elements to the microlayer from the Saharan dust. However, the reactive fraction of the suspended particles increased over time, indicative of scavenging. Based on the artificial dust deposition experiment, aerosols should be retained in the sea surface microlayer long enough to undergo chemical and physical alteration that affects the bioavailability of trace elements. Opportunistic bacteria (example: Vibrio spp.) have been shown to experience rapid growth during dust deposition events. Aerosols and microlayer samples were collected in the Florida Keys over the course of two years for analysis of dissolved and particulate Al, Mn, Fe, Co, Ni, Cu, Zn, and Pb. Trace element concentrations increased by factors of 2 to 5 in the microlayer during significant Saharan dust events. Residence times of dissolved trace elements ranged from 0.12 hours for Mn to 2.4 hours for Cu. Residence times of particulate trace elements ranged from 1.1 minutes for Co to 2.4 minutes for Mn. The particulate residence times were comparable between the artificial deposition experiment and the natural deposition event observed in the Florida Keys. The relatively short residence times for dissolved trace elements compared to the artificial deposition event suggest external forces, such as wind and wave actions, mixed the dissolved metals faster than by simple molecular diffusion. Despite the short residence times, Vibrio spp. in the microlayer increased by factors of 2 to 10 after the passage of a Saharan dust event, which suggests that there was an initial pulse of bioavailable trace elements and other nutrients to the system. These findings demonstrate the dynamic nature of the sea surface microlayer and the large role atmospheric deposition can play when introducing trace elements to the surface oceans. It also sheds light on the need for more interdisciplinary research to deconvolute and quantify the processes occurring in the microlayer.

Show moreThe aging population is expected to increase substantially in the future. The fatal crash rates (per mile traveled) involving older drivers (65+) are considerably higher than those of younger drivers. This research involved conducting computational experiments involving dummy models to investigate the biomechanics of older drivers in vehicular crashes. Before conducting these experiments, the concepts of biological changes in older populations needed to be addressed. This allowed us to first find out what makes the older drivers different from younger drivers. It was found that driving posture is one of the two key differences between the two age groups. The Hybrid III computational dummy model was used to investigate the effect of driving posture. The other key finding shows that older drivers are affected by aging factors such as material properties decrease and thickness decrease of bones. The Total Human Model for Safety (THUMS) was used because it can be modified to represent an aged driver to be used in the crash simulations. For the posture investigation, the idea is that driving posture for older drivers tend to be closer to the steering wheel whereas younger drivers are more laid back was incorporated. All computational work was completed in LS-DYNA; a finite element code used for non-linear impact analysis. The Finite Element (FE) simulation was validated by comparing the FE results with physical crash test results. These results were found in the Federal Motor Vehicle Safety Standards and Regulations (FMVSS) Report 208 for Frontal Crash Test. For subsequent simulations, posture changes based on the idea of aging according to literature review were implemented. For the Head Injury Criteria, the extended shoulders of an older driver yielded percent differences as high as 16%. The arms acted like braces to restrain the torso while the head continued forward. The extended knees also yielded a 16% increase in head injury. As for the chest acceleration, the extended hip and torso joints showed increased values. It was concluded that sitting closer was beneficial for the Head Injury Criteria but the opposite was true for the chest acceleration. The posture changes did not affect the pelvis acceleration. This investigation gave us a better understanding of what occurs in automobile accidents specific to older occupants. This knowledge can be useful in designing engineering approaches to mitigate injuries. Using the aged model, the material properties decrease yielded the highest chest deflection of 13.3%. For the bone thickness decrease, the chest acceleration showed the highest increase of 12.5%. The head acceleration and chest deflection showed noticeable increases. Overall with all three aging factors in place, the head and chest accelerations yielded high increases. Whereas for the deflection, it remains the same. The thoracic rotation increased the head resultant acceleration. The rotation decreased the deflection of the thorax because the ribs were more in line with the force imposed by the crash. It can withstand more force when the ribs are more parallel with the force. As for the chest acceleration, no significant change was present. It can be concluded that the older drivers in rear impacts experienced higher (Neck Injury Criterion) NICmax than younger drivers as much as 6.9% percent for the material property decrease and bone thickness decrease. The thorax rotation yielded a 4.7% decrease in NICmax. It is possible that this aging factor caused the thorax to conform more into the seatback thus reducing the injury. The bone thickness decreased affected the NICmax greatly whereas the material property decreased did show signs of minimal positive influence. The material property decreased yielded 0.8% increase while the thickness decreased yielded a 3.0% increase.

Show moreBlood Vinyls investigates the definition of 'Memory in the blood,' or 'blood memory,' which is defined as one's ancestral or genetic connection to their language, songs, spirituality, and teachings" (Huang 6), as well as Toni Morrison's provocative term rememory. In her novel Beloved, Morrison defines rememory as a "picture floating" and a "thought picture" as a "rememory that belongs to somebody else can be bumped into"; Morrison's definition also asserts that this rememory exists in a space "where [one] was before [they] came here" (43-4). I extend Morrison's definition through this manuscript by signifying upon these definitions as poetic manifestations in order to connect these blood memories to the playing of vinyl records—including the sounds made by vinyl record players as a way to elicit, invoke, interrogate and (re)create memories. Because of the multifunction of vinyl in this collection, it is my attempt to expand the parameters of how poets can use the craft of synesthesia. This need for this expansion is critical because Blood Vinyls connects synesthesia to the African American musical tradition call and response, but in this case, the speakers or singers in these poems are not only responded to or echoed by one or more voices/singers in the poems by people and characters closely intertwined in the poet's life, but these responders are also the readers of these poems—listeners who participate in this interaction. The first line of James Longenbach's The Art of the Poetic Line, "Poetry is the sound of language organized in lines" (xi) posits a key component of the definition of poetry that also supports the plausibility for my connections between poetry, music, and memory.

Show moreBlood We Did Not Spill, a historical political novel, begins in June 1997 when a young Indian Police Services officer stops at a small town to visit a retired police officer—delusional and very sick—on behalf of her boss. She sees him briefly, speaks with the family and then leaves. Fifteen days later she returns to the same town to take charge of a prison-in-flux on a temporary basis. She is the first woman in the history of the police force to be given this posting, only for five days while the officer-in-charge is on vacation. The prisoners of K—Jail are being moved to a newer facility and whilst most of them have been transferred, the young officer must oversee the relocation of one small group—dacoits—serving life terms. During the transfer she uncovers a discrepancy amongst these prisoners; an extra man is found. This discovery is further compounded by the fact that none of the prisoners will answer her questions honestly or directly. At the time it becomes difficult for her to find out the true identity of the men through official means. Pertinent files from the records room are missing. Instead, she finds a manila envelope containing illegible papers with blood splatter on them and letters—official and love letters—dating from 1977 onwards till 1996. The country has shut down for an extended religious holiday so she cannot get duplicate records that are kept at headquarters. What she learns from these men helps her put together some of the pieces of the puzzle that involve the retired police officer she visited, now deceased, and his twin daughters. Other events that play a part, especially those that happened during The Emergency of 1975-1997, a period that is considered one of the most controversial of Independent India’s history, come to light. With limited time on her, and pressure building, her investigation leads her to events historically rooted in the mistakes made by another pioneering woman—Indira Gandhi, India’s first female Prime Minister—and her allies. How the police officer conducts her investigation and what she chooses to do with the results of the discrepancy irrevocably changes the lives of all the people involved.

In the narrative’s substantial revision, I will utilize a dualistic time structure—one timeline in the past, when Kalki the child first starts to doubt his own divinity, and one timeline in the present moment, when a twenty-two-year-old Kalki runs away while visiting New York City and tries to discover who he really is. In the arc of the novel, Kalki...
Show moreBlue-Skinned Gods follows the story of Kalki, a young boy who is worshipped by a Hindu cult as the next and last incarnation of the god Vishnu. In the narrative’s substantial revision, I will utilize a dualistic time structure—one timeline in the past, when Kalki the child first starts to doubt his own divinity, and one timeline in the present moment, when a twenty-two-year-old Kalki runs away while visiting New York City and tries to discover who he really is. In the arc of the novel, Kalki starts out believing himself a real god incarnate. The book traces his dawning recognition of his own humanness, and his dilemma in figuring out how to have hope after he loses his faith.

Title: Bohuslav Martinů and His First Cello Sonata: A Performance Guide.
Creator: Carey, Meghan Anne, Sauer, Greg, Jones, Evan Allan, Jiménez, Alexander, Sung, Benjamin, Florida State University, College of Music
Abstract/Description: The First Sonata for Cello and Piano by Bohuslav Martinů (1890-1959) is a work that has been undeservingly neglected in performance history. This treatise makes this work more approachable for performers, from both a musical and a technical standpoint. The historical and musical context of the piece was examined, and the work was analyzed from a performer's perspective. This treatise presents these findings, followed by a series of preparatory technical exercises for the cello.

Show moreThe purpose of this document is to make the reader aware of two areas of vocal Brazilian music that have long been neglected, and are now receiving the attention of researchers and performers: Brazilian Portuguese lyric diction and the operas of Brazilian composer Antônio Carlos Gomes. Many people are familiar with popular genres of Brazilian music. The samba, bossa nova, choro and the driving rhythms associated with carnival dances are widely popular among the general public. However, few are familiar with the classical vocal repertoire. The first section is dedicated to pedagogical tools for teaching Brazilian Portuguese diction. American singers will find the process of preparing Brazilian repertoire more accessible with this concise but objective guide. The second half is a discussion of the operatic works of Antônio Carlos Gomes, with focus on Gomes as a transitional figure from the bel canto to verismo in Italy in the second half the 19th century, as well as his contributions to the operatic repertoire.

Show moreThis work examines the Iranian Crisis of 1946 and its active role in shaping the Cold War that followed. It is intended to serve as a case study of how the United States was able to successfully flex its short-lived atomic monopoly and achieve its international objectives in the early postwar era by means of direct engagement with so-called "peripheral actors." This writing engages with the robust academic field of U.S. foreign relations that over the past number of years revisited and reimagined the origins and driving forces of the Cold War. My own international archival research and comparative historiographical analysis supports the growing synthesis of the field, and it has led me to argue the importance of peripheral actors, and specifically Iran, in establishing the Cold War system. The claims that Soviet expansionism or American economic agendas were the sole agitants behind the emergence of the decades-long struggle no longer satisfies in lieu of the new materials and analytical approaches now available. While the Russians and the British jockeyed for positions of leadership within wartime-occupied Iran, the United States was welcomed into the region by many Iranians as a potential balancing force and check on European imperialism. The Soviet Union's violation of a troop withdrawal agreement at the conclusion of the Second World War, coupled with its active support of Kurdish and Azeri separatist movements, aggressively tested the new and evolving international order. The primary objective of this work is to understand how the international community, in this case led by the United States, the Soviet Union, Iran, and the newly-formed United Nations, achieved a relatively peaceful withdrawal of Soviet forces from Iranian territory. I contend that: 1) Iran possessed, due to its wartime role and latent economic potential, a degree of leverage in negotiations with the United States and Russia that other nations did not; 2) that the Iranian prime minister, Ahmad Qavām, shrewdly manipulated both superpowers with his own brand of masterful statecraft while pursuing his own "Iran-centric" objectives; 3) that the United States used its preponderance of military, economic, and diplomatic might to effectively achieve its postwar aims; and 4) the primary actors in the crisis solidified the legitimacy of the United Nations and its Security Council, which had previously been in jeopardy. The Iranian Crisis presents a challenge to those scholars who present models premised on a rigid Cold War binarism, while it seemingly strengthens the case of those scholars who take account of other actors when assessing power dynamics and the ability of the superpowers to implement their will. Evidence indicates that Prime Minister Qavām was one of the principal figures behind the peaceful resolution of this matter. Representing a "third-party" force outside of Europe, Qavām skillfully used the tools he had at his disposal to transform the foreign policies of the superpowers while advancing his own country's agenda. Qavām would not have taken the bold risks that he did – which included offering highly sought after oil concessions to Soviet leaders while deftly wrapping them in legalistic parlance and damning requirements – unless he was positive that the United States would stand behind him militarily, economically, and politically, even if doing so risked the continuation and perhaps escalation of global conflict. While lesser known than the Berlin Airlift or the Korean War or the Cuban Missile Crisis, the Iranian Crisis revealed for the first time what a superpower clash might look like. This event provides a stunning example of crisis management by the primary participants. The Iranian Crisis was indeed the birth of the Cold War, and it established a model for state actions during and after this long conflict. The Crisis also provides a powerful example of how third-party entities outside of Europe, despite possessing relatively meager military and economic might, had the ability to alter and occasionally manipulate superpower behavior.

Show morePersonality trait approaches have proven highly valuable in the study of mental health problems, but their value could be enhanced by interfacing trait constructs more clearly with variables in the domain of biology. The current research sought to interface the five factor model (FFM) of personality with the triarchic neurobehavioral trait framework, a model that focuses on dimensions that have a basis in both behavior and physiology. Study 1 utilized a large sample of adults and undergraduates (N = 861) to investigate the intersections of the FFM and triarchic models. FFM domains and facets were measured using the NEO-PI-R (Costa & McCrae, 1992), while the triarchic dimensions were modeled as latent factors using Confirmatory Factor Analysis (CFA). The domains of the FFM showed complex, configural relations with triarchic CFA factor scores. Further, this study demonstrated that the NEO-PI-R can be reconfigured to index the triarchic model constructs though the construction of item-based NEO-Triarchic scales (NEO-Tri) using an established consensus rating approach. The triarchic CFA factors and FFM domains predicted significant variance in self-reported antisocial behavior and substance use, and this prediction was maintained for reconfigured NEO-Tri scales. Study 2 (N = 212 undergraduates and adults from the community) utilized data from a multi-domain assessment study that included questionnaire inventories, physiological testing, and structured diagnostic interviewing, to demonstrate how reconfiguring the FFM to index the triarchic model constructs can enhance its predictive association with brain response (a factor defined by event-related potentials derived from three separate tasks) while maintaining robust associations with symptoms of psychopathology. The current work illustrates the utility of interfacing the FFM and triarchic neurobehavioral trait models as a basis for linking psychopathology more effectively to neurobiological concepts and measures. The benefits of focusing on neurobehavioral trait constructs more broadly as targets of psychopathology research are also discussed.

Show moreIn this study, I employed a mixed-method design to understand how nonprofit resource centers originate, operate, and evolve using a transaction cost framework to evaluate both sides of the supply vs. demand equation. The quantitative study of 125 nonprofits identified and assessed demand side factors of need, benefits and barriers. This study found that nonprofit resource centers can structure their agency design to enhance likelihood of survival. The national qualitative study of 25 nonprofit resource centers found that supply side factors of leadership, funding, and stakeholder engagement were more significant to organizational development and progression through the life cycle model. This study initially undertook an inductive approach to assess these organizations’ dynamically evolving identities as they transitioned through the nonprofit life cycle stages. A relationship between life cycle stage and organizational identity was established based on common drivers. A theoretical typology of power, autonomy and organizational development was postulated.

Show moreComputational thinking is increasingly recognized as an important skill set to learn for people living in the 21st century, and the middle school years comprise a critical stage to introduce children to computational thinking. Video game based learning is a promising way to foster computational thinking among middle school students, however, it is relatively less researched compared to other methods. In this dissertation study, I evaluated the effectiveness of a video game Penguin Go on developing middle school students’ computational thinking skills, as well as on improving their attitudes toward computer science. I designed Penguin Go to cover the core components of computational thinking, including problem decomposition, abstraction, algorithmic thinking, conditional logic, iterative thinking, and debugging. I implemented the game based on Blockly, a block-based programming language. The game was evaluated with 43 middle school students during two weeks. In addition to the overall effectiveness of the game, I aimed to investigate the impact of a specific game feature—constraints on the number of blocks in a solution—on both students’ computational thinking skills and their attitudes toward computer science. Results showed that after playing Penguin Go for less than two hours, students’ computational thinking skills improved significantly, however, the additional constraints did not generate a significant impact on learning gains. Also, the game did not bring about significant attitudinal changes among students. The additional constraints, however, resulted in a significant negative change in students attitudes toward computer science. Implications of the findings and possible directions for future research regarding using these types of games to foster computational thinking are discussed.

Using a randomized control trial, this study examined the causal effect of cross-language transfer of phonological awareness using data from multilingual first-grade children from Kenya. The sample comprised of (N = 300) children whose mother tongue (L1) was a local ethnic dialect of Kenya (i.e. Lunyala); who also speak the dominant language Swahili, the East African Lingua Franca; and are learning English in school through immersion. They were drawn from four public schools. Children from each school randomly assigned to a treatment and a control group. Participants in the treatment group received an eight-week letter knowledge and phonological awareness training that entailed metalinguistic games and exercises in Swahili in addition to their regular classroom instruction. The program was delivered three times a week in 20 minute sessions to small groups (N = 3 children per group). The control group received no treatment. The children were assessed on their letter knowledge, phonological awareness, word reading, oral reading fluency and receptive vocabulary in Swahili and English. The results revealed that children in the treatment group showed greater improvement in Swahili skills such as letter knowledge, phonological awareness, and word reading ability. Importantly, these children also showed statistically significant improvement in English letter sound knowledge and phonological awareness, indicating cross-language transfer. The outcomes between the two treatment conditions did not differ as function of vocabulary, language spoken at home, socio-economic status or absence from school. This study provides causal evidence about cross-language transfer of phonological awareness. High quality phonological and letter knowledge training in familiar language is important for classroom practioners in multilingual settings.

Show moreStructural biology has been successful in the characterization of soluble protein, which has given insight in the inner working of several thousands of proteins. However, structural characterization of proteins has been limited in two areas. One area corresponds to the rise on interest on intrinsically disorder proteins. This kind of proteins has changed the structure-function paradigm since they can perform important cellular function without a defined three dimensional structure. The second are is the characterization of membrane proteins, which contrary to soluble proteins, they are embedded in an anisotropic environment that makes them difficult to characterize. This dissertation work was focused in the characterization of two important membrane proteins involved in cell division of Mycobacterium tuberculosis, ChiZ and FtsX. The first part of this work is related to the characterization of ChiZ, a cell division protein possibly involved in peptidoglycan remodeling and control of cell division progression. Structural characterization of ChiZ was mainly focused on the N-terminal soluble region that is intrinsically disordered. This region was previously identified to have peptidoglycan hydrolysis activity. Thus, a combination of solution and solid state NMR to characterize the structure of ChiZ N-terminal region in solution and in the full length protein reconstituted in liposomes. In addition to solution NMR, ChiZ N-terminal intrinsically disordered region was characterized with other method including circular dichroism, dynamic light scattering, size exclusion chromatography and small angle X-ray scattering. Thus, the objective was to obtain a clear picture of the behavior of the intrinsically disordered region in solution. Furthermore, characterization of ChiZ peptidoglycan hydrolysis activity was attempted with the goal of correlating structural properties of the N-terminal region and the protein function. The second part of this study focuses on the challenges of working with membrane proteins. The subject of study was FtsX, a membrane protein is one of the components of the cell division machinery or divisome. This part of the work attempts to give a general guideline for optimizing membrane protein purification and reconstitution with large emphasis on detergent selection. Detergent selection can affect each step of FtsX work, from protein purification to membrane protein reconstitution and sample preparation for solid state NMR experiments.
