Description
Formed in 1999, BCM International, comprised of composers Eric Whitacre, Jonathan Newman, Steven Bryant, and James (Jim) Bonney dedicated itself to publishing repertoire in the wind band medium. This project focuses on the work of these four composers, who, at the beginning of the “digital age,” joined together to create a new entrepreneurial and self-published entity. This paper aims to discuss their contribution to the wind band medium, thereby adding to the genre’s body of research.
Similarly to previous investigations of this sort, the author will: 1) offer a biographical sketch through the lens of each individual composer; 2) discuss the establishment of BCM International; 3) track the individual output for wind band of each of the four composers through performance data found in the College Band Directors National Association’s Report; and 4) discuss the composer reported influence of John Corigliano, their teacher, on their compositional process.

Description
Composite materials are finally providing uses hitherto reserved for metals in structural systems applications – airframes and engine containment systems, wraps for repair and rehabilitation, and ballistic/blast mitigation systems. They have high strength-to-weight ratios, are durable and resistant to environmental effects, have high impact strength, and can be manufactured in a variety of shapes. Generalized constitutive models are being developed to accurately model composite systems so they can be used in implicit and explicit finite element analysis. These models require extensive characterization of the composite material as input. The particular constitutive model of interest for this research is a three-dimensional orthotropic elasto-plastic composite material model that requires a total of 12 experimental stress-strain curves, yield stresses, and Young’s Modulus and Poisson’s ratio in the material directions as input. Sometimes it is not possible to carry out reliable experimental tests needed to characterize the composite material. One solution is using virtual testing to fill the gaps in available experimental data. A Virtual Testing Software System (VTSS) has been developed to address the need for a less restrictive method to characterize a three-dimensional orthotropic composite material. The system takes in the material properties of the constituents and completes all 12 of the necessary characterization tests using finite element (FE) models. Verification and validation test cases demonstrate the capabilities of the VTSS.

Description
This study investigates degree perseverance among African Americans who transitioned from an undergraduate music program at a Historically Black College and University (HBCU) to a Predominantly White Institution (PWI). A framework based on Bourdieu’s cultural capital theory and Yosso’s community cultural wealth theory was employed to examine how academic, cultural, and social aspects of participants’ undergraduate and graduate school experiences influenced their perseverance. Because those aspects are intricately intertwined with race, I also employed critical race theory and double consciousness theory, and used Angela Duckworth’s Grit Scale to measure degree perseverance.
Eight African American male instrumental music educators participated in this study. Research questions included: What are the experiences of African Americans who have transitioned from undergraduate music programs at HBCUs to graduate music programs at PWIs?; How do these individuals compare academic, social, and cultural aspects of their experiences within two institutional environments?; What are their self-perceptions of their own degree perseverance?; and, What social, cultural, and academic aspects of their experiences influenced their perseverance?
After developing a portrait of each participant’s pre-college and college experiences, analysis reveled that participants were very persistent; however, academic, cultural, social, and racial experiences influenced their perseverance. Participants employed dominant cultural capital and community cultural wealth as well as their “Grittiness” to successfully transition from an HBCU to a PWI.
Recommendations for HBCUs, PWIs, and the profession are offered toward improving the experiences of African American music students in higher education. HBCUs must hold their faculty and students accountable for developing a broader musical experience beyond marching band, and address colorism on their campuses. PWIs should recognize and accept the capital that African Americans bring, acknowledge that African Americans need access to social support networks, and assess how their environments, actions, and decisions may devalue or discount African Americans. While more research is needed regarding the experiences of African Americans in music programs, African American students must also take active roles in shaping their own educational experiences by seeking assistance that will improve their experiences.

Description
A simplified bilinear moment-curvature model are derived based on the moment-curvature response generated from a parameterized stress-strain response of strain softening and or strain-hardening material by Dr. Barzin Mobasher and Dr. Chote Soranakom. Closed form solutions are developed for deflection calculations of determinate beams subjected to usual loading patterns at any load stage. The solutions are based on a bilinear moment curvature response characterized by the flexural crack initiation and ultimate capacity based on a deflection hardening behavior. Closed form equations for deflection calculation are presented for simply supported beams under three point bending, four point bending, uniform load, concentrated moment at the middle, pure bending, and for cantilever beam under a point load at the end, a point load with an arbitrary distance from the fixed end, and uniform load. These expressions are derived for pre-cracked and post cracked regions. A parametric study is conducted to examine the effects of moment and curvature at the ultimate stage to moment and curvature at the first crack ratios on the deflection. The effectiveness of the simplified closed form solution is demonstrated by comparing the analytical load deflection response and the experimental results for three point and four point bending. The simplified bilinear moment-curvature model is modified by imposing the deflection softening behavior so that it can be widely implemented in the analysis of 2-D panels. The derivations of elastic solutions and yield line approach of 2-D panels are presented. Effectiveness of the proposed moment-curvature model with various types of panels is verified by comparing the simulated data with the experimental data of panel test.

Description
When dancers are granted agency over music, as in interactive dance systems, the actors are most often concerned with the problem of creating a staged performance for an audience. However, as is reflected by the above quote, the practice of Argentine tango social dance is most concerned with participants internal experience and their relationship to the broader tango community. In this dissertation I explore creative approaches to enrich the sense of connection, that is, the experience of oneness with a partner and complete immersion in music and dance for Argentine tango dancers by providing agency over musical activities through the use of interactive technology. Specifically, I create an interactive dance system that allows tango dancers to affect and create music via their movements in the context of social dance. The motivations for this work are multifold: 1) to intensify embodied experience of the interplay between dance and music, individual and partner, couple and community, 2) to create shared experience of the conventions of tango dance, and 3) to innovate Argentine tango social dance practice for the purposes of education and increasing musicality in dancers.

Description
The Sonata for Cello and Piano (1915) was one of the last three sonatas written by Claude Debussy (1862–1918). When Debussy composed the sonata, France was involved in World War I and Debussy was influenced by political dogmas that sought to advance nationalism as well as the use of French traditions in musical compositions. By discussing the political impact of World War I on French music, this paper will place the Sonata in a context that strengthens the understanding of the work.
Debussy, who participated in the political project of seeking out tradition as the protector of French culture, also presents his understanding of what French tradition is in this sonata. An analytical description of the structure, thematic materials, harmonies and intervallic relationships of the Sonata reveals Debussy’s approach of combining the elements that he observed from his French predecessors, as well as his own innovations in the work as he negotiated musical world that was controlled by political dogma

Description
Unidirectional glass fiber reinforced polymer (GFRP) is tested at four initial strain rates (25, 50, 100 and 200 s-1) and six temperatures (−25, 0, 25, 50, 75 and 100 °C) on a servo-hydraulic high-rate testing system to investigate any possible effects on their mechanical properties and failure patterns. Meanwhile, for the sake of illuminating strain rate and temperature effect mechanisms, glass yarn samples were complementally tested at four different strain rates (40, 80, 120 and 160 s-1) and varying temperatures (25, 50, 75 and 100 °C) utilizing an Instron drop-weight impact system. In addition, quasi-static properties of GFRP and glass yarn are supplemented as references. The stress–strain responses at varying strain rates and elevated temperatures are discussed. A Weibull statistics model is used to quantify the degree of variability in tensile strength and to obtain Weibull parameters for engineering applications.
