Motivation and Identity in an American Irish Music Community

Music is about the people who play it, not the music itself. This statement by Se&Atilde;&iexcl;n Keane, an Irish fiddler I interviewed in County Clare, Ireland, gets at the very root of Irish traditional music. People who seek out and play Irish traditional music do so not only for the sake of the music itself, but for a wide variety of personal reasons that have more to do with their own physical, mental, and emotional needs. The motivations behind this drive to musical participation are as varied as the people themselves, as are the effects these motivations have on personal identity. Motivation, musical participation, and identity are indelibly linked in a mutable and highly individual manner, and the depth to which these motivations and the music produced affects personal identity varies according to how important those motivations are and how meaningful are the personal rewards musical participation brings to the musician. This dissertation examines the motivations of musicians in three Irish traditional instrumental music sessions in Albuquerque, New Mexico in which I conducted fieldwork from September of 2014 to November of 2015. I analyze motivations for participation in the Albuquerque Irish traditional music scene in three broad categories: music as a social outlet, music as therapy, and music as a learning experience. This three-part analysis reveals how different motivational factors impact the practice of Irish traditional music in America as well how those motivations and the music itself affect individual identities among participants in these groups. These findings have implications for how we understand music making in settings where musical participation is not driven by the desire to enact an ethnicity, for financial gain, or in order to satisfy the expectations of others. A better understanding of why people participate in amateur traditional music groups can help us to understand the needs of those people and how music satisfies those needs and fulfills their desires.</p

The effect of Smog-Ozone warnings and a vanpool program on traffic volume in york county of south carolina

Ground-level ozone is a critical criteria pollutant that is significantly generated by transportation patterns. We study the effect of smog–ozone warnings, triggered by the Environmental Protection Agency, on traffic volume in York County, South Carolina during the period 2006–10. In addition, the subperiods 2006–07 and 2008–10, where the ozone smog-alert thresholds 0.080 parts per million (ppm) and 0.075 ppm, respectively, are examined. The approach followed in this paper is a differences-in-differences (DID) regression. Additionally, a regression discontinuity design in the DID framework is applied. We find a negative and significant decrease in weekday peak-hour traffic volume in the treatment group during 2008–10

Detection of interstellar H 2 CCCHC 3 N: A possible link between chains and rings in cold cores

Context. The chemical pathways linking the small organic molecules commonly observed in molecular clouds to the large, complex, polycyclic species long suspected of being carriers of the ubiquitous unidentified infrared emission bands remain unclear. Aims. To investigate whether the formation of mono- and polycyclic molecules observed in cold cores could form via the bottom-up reaction of ubiquitous carbon-chain species with, for example, atomic hydrogen, a search is made for possible intermediates in data taken as part of the GOTHAM (GBT Observations of TMC-1: Hunting for Aromatic Molecules) project. Methods. Markov chain Monte Carlo (MCMC) source models were run to obtain column densities and excitation temperatures. Astrochemical models were run to examine possible formation routes, including (a) a novel grain-surface pathway involving the hydrogenation of C6N and HC6N, (b) purely gas-phase reactions between C3N and both propyne (CH3CCH) and allene (CH2CCH2), and (c) via the reaction CN + H2CCCHCCH. Results. We report the first detection of cyanoacetyleneallene (H2CCCHC3N) in space toward the TMC-1 cold cloud using the Robert C. Byrd 100 m Green Bank Telescope. Cyanoacetyleneallene may represent an intermediate between less-saturated carbon chains, such as the cyanopolyynes, that are characteristic of cold cores and the more recently discovered cyclic species, such as cyanocyclopentadiene. Results from our models show that the gas-phase allene-based formation route in particular produces abundances of H2CCCHC3N that match the column density of 2 × 1011 cm−2 obtained from the MCMC source model, and that the grain-surface route yields large abundances on ices that could potentially be important as precursors for cyclic molecules.</jats:p
