Influences on career choice in music education audition candidates: Pilot study

The purpose of this pilot study was to survey prospective undergraduate music education majors to learn what motivated them to aspire to a career in music education. Respondents were candidates auditioning, but not yet accepted, for music teacher preparation programs at four institutions (N = 228). Findings corroborate prior research that suggests that school music teachers and/or private lesson teachers are highly influential. This study sought to quantify the types of experiences participants had in teaching roles at the time of their college audition, supporting other research suggesting that such experiences may increase interest in a music teaching career. Recommendations include engaging music educators at all PreK–12 levels in actively recruiting and encouraging future teachers, providing private instructors and performance majors with teacher recruitment information, emphasizing earlier identification and preparation of prospective educators, and refining and continuing the work begun in this pilot study.

Career Influences of Music Education Audition Candidates

In this descriptive study, we examined the influences and experiences motivating students to enter college-level music schools as reported by a population of precollegiate students auditioning (but not yet accepted) to music education degree programs. As a follow-up to a published pilot study, this research was designed to quantify the various experiences respondents had as part of their precollege school and community programs that related to teaching and music. Results indicate a strong connection between respondents’ primary musical background and future teaching interest. The top three influential experiences were related to high school ensemble membership (band, choir, orchestra), and the most influential group of individuals in the decision to become a music educator were high school ensemble directors. Respondents from all four primary background groups (band, choir, orchestra, and general or other) rated private lesson teaching as their second strongest future teaching interest, just behind teaching at the high school level in their primary background. Respondents rated parents as moderately influential on their desire to become a music teacher.

Climate Change Adaptation Tool for Transportation: Mid-Atlantic Region Case Study

Transportation has contributed to climate change and will most likely be impacted by changes in sea level, temperature, precipitation, and wind, for example. As the risk of climate change impacts become more imminent, pressure for adaptation within transportation agencies to address these impacts continues to rise. The most logical strategy is to integrate consideration of adaptation projects into the long-range transportation planning (LRTP) process. To do this, tools and experience are needed to assist transportation agencies. The Climate Change Adaptation Tool for Transportation (CCATT) is a step-by-step method to evaluate climate change scenarios and impacts, inventory at-risk existing and proposed infrastructure, and assess mitigation practices to identify supporting adaptation efforts. This paper focuses on the application of CCATT to the Mid-Atlantic region using a case study on the Wilmington Area Planning Council (WILMAPCO), the Metropolitan Planning Organization for northern Delaware. The results of the application and case study demonstrate the importance of climate change adaptation practices in long-range transportation planning. DOI: 10.1061/(ASCE)TE.1943-5436.0000515.

Synthesis of Mid-Chain Functionalized Polymers

Polymers with mid-chain alkoxyamine functionality were synthesized by activating monohalogenated polymers in the presence of nitroso or nitrone radical traps. The resulting polymers were either polystyrene (PSt) homopolymers with a mid-chain alkoxyamine or PSt-poly(methyl acrylate) (PMA) diblock copolymers with an alkoxyamine unit at the junction between the segments. Monohalogenated polymers where synthesized by atom transfer radical polymerization (ATRP) and were then reacted to form polymer radicals in the presence of a radical trap, nitrone or nitroso. When only polystyrene radicals were reacted with the radical trap a dimer was formed with an alkoxyamine functionality in the center of the polymer chain. This functionality allowed the polymer chain to be cleaved in order to visualize the extent of the alkoxyamine functionality incorporation into the polymer chains. It was found that near quantitative alkoxyamine mid-chain functionality could be achieved by activating the PStBr in the presence of 10 equivalents of nitrone, 5 equivalents of copper bromide, and 2 equivalents of copper metal. Further reducing the amount of copper metal led to incomplete coupling, while increasing the equivalents beyond 2 generated polymer dimers with less than quantitative mid-chain functionality. Monochlorinated polystyrene (PStCl) precursors gave much poorer coupling results compared to reactions with PStBr, which is consistent with the stronger C-Cl bond resisting activation and the formation of the polystyryl radicals. When poly (methyl acrylate) (PMABr) is reacted with PStBr in the presence of a nitroso group at reduced temperatures (30 oC) block copolymers were selectively formed with an alkoxyamine functionality in the center. This was done by first activating the PSt-Br to form a polymer radical that would react with the radical trap to form a persistent radical on the oxygen. The PMA-Br, once activated, reacted with the radical on the oxygen to form the block copolymer. To test the amount of functionality incorporated, a coupling reaction was performed with no nitroso present, and found that no reaction occurred. This showed that the radical trap is essential for the coupling to occur, and cleavage of the diblock indicated that the alkoxyamine functionality was indeed incorporated into the diblock.

Further Evidence for Hemisity Sorting During Career Specialization

Hemisity refers to binary thinking and behavioral style differences between right and left brain-oriented individuals. The inevitability of hemisity became clear when it was discovered by magnetic resonance imaging (MRI) that an anatomical element of the executive system was unilaterally embedded in either the right or the left side of the ventral gyrus of the anterior cingulate cortex in an idiosyncratic manner that was congruent with an individual's inherent hemisity subtype. Based upon the MRI-calibrated hemisity of many individuals, a set of earlier biophysical and questionnaire hemisity assays was calibrated for accuracy and found appropriate for use in the investigation of the hemisity of individuals and groups. It had been reported that a partial sorting of individuals into hemisity right and left brain-oriented subgroups occurred during the process of higher education and professional development. Here, these results were extended by comparison of the hemisity of a putative unsorted population of 1,049 high school upper classmen, with that of 228 university freshmen. These hemisity outcomes were further compared with that of 15 university librarians, here found to be predominantly left brain-oriented, and 91 academically trained musicians, including 47 professional pianists, here found to be mostly right brainers. The results further supported the existence of substantial hemisity selection occurring during the process of higher education and in professional development.
