John Cage’s ‘Rock’ Music: Ecocritical and Performance Considerations in Ryoanji for Solo Oboe and Percussion Obbligato (1983)

In the years following World War II, several American composers began breaking from the confines of music notation relegated to five lines and four spaces. Of particular interest to this study, John Cage (1912–1992) began liberating his compositions from the restraint posed by traditional notation in 1951 with his work Imaginary Landscape No. 4. He continued to create and develop varying systems of graphic notation with his indeterminate works, which became increasingly influenced by his interest in the environment and in South and East Asian aesthetic and philosophical considerations, themselves environmentally influenced. One of the latest products of Cage’s coalescence of Asian aesthetics and graphic notation was Ryoanji for solo oboe with percussion obbligato (1983). Inspired by his visit to the Ryōan-ji dry landscape garden in Kyoto, Japan, Cage created graphic notation for his piece bearing the same name by tracing the contours of fifteen rocks onto modified manuscript staves. Although significant research examines the Asian philosophical and aesthetic influences on John Cage’s compositions, and more recent scholarship has examined his works through the lens of ecocritical methodologies, very little critical attention has been given to the ways in which environmentalism informed his compositional process. Furthermore, even less has been given to performance practice considerations in his works. By examining Ryoanji through an ecocritical lens and exploring the impact of Cage’s relationship with the natural environment on his compositional process in this piece, this monograph will show that Cage’s ecomusicological aesthetic was used to inform his works and specifically this piece. Additionally, this study will offer an ecocritical reading of Ryoanji to illustrate how Cage’s environmental considerations could inform performing practices of Ryoanji for Solo Oboe and Percussion Obbligato

World Vaping Day: Contextualizing Vaping Culture in Online Social Media Using a Mixed Methods Approach

Few studies have demonstrated the use of mixed methods research to contextualize health topics using primary data from social media. To address this gap in the methodological literature, we present research about electronic nicotine delivery systems, using Twitter data from “World Vaping Day.” To engage with the quantitative breadth and qualitative depth of 5,149 collected tweets, we utilized a convergent parallel mixed methods framework, integrating thematic prevalence estimates with phenomenological contextualization. Sentiment was more positive than negative across all categories except policy related. A total of 23% of tweets were promotional and relatively few tweets related to tobacco use (4.9%) or health concerns (4.2%). Salient themes included modifying or upgrading electronic nicotine delivery systems devices, and general mistrust of public health advocates and tobacco companies. </jats:p

Validation of Atmospheric Profile Retrievals from the SNPP NOAA-Unique Combined Atmospheric Processing System. Part 2: Ozone

This paper continues an overview of the validation of operational profile retrievals from the Suomi National Polar-Orbiting Partnership (SNPP), with focus here given to the infrared (IR) ozone profile environmental data record (EDR) product. The SNPP IR ozone profile EDR is retrieved using the cross-track IR sounder (CrIS), a Fourier transform spectrometer that measures high-resolution IR earth radiance spectra containing atmospheric state information, namely, vertical profiles of temperature, moisture, and trace gas constituents. The SNPP CrIS serves as the U.S. low earth orbit (LEO) satellite IR sounding system and will be featured on future Joint Polar Satellite System (JPSS) LEO satellites. The operational sounding algorithm is the National Oceanic and Atmospheric Administration-Unique Combined Atmospheric Processing System (NUCAPS), a legacy sounder science team algorithm that retrieves atmospheric profile EDR products, including ozone and carbon trace gases, with optimal vertical resolution under nonprecipitating (clear to partly cloudy) conditions. The NUCAPS ozone profile product is assessed in this paper using extensive global $in\;situ$ truth data sets, namely, ozonesonde observations launched from ground-based networks and from ocean-based intensive field campaigns, along with numerical weather prediction model output. Based upon rigorous statistical analyses using these data sets, the NUCAPS ozone profile EDRs are determined to meet the JPSS Level 1 global performance requirements

Neutron total cross sections on protons and nuclei in the 10 to 30 GeV/c momentum range

We present the results of a recent AGS measurement of the total cross section for neutrons on protons, deuterons and other nuclei in the momentum range 10 to 30 GeV/c. The standard good-geometry transmission technique was used with a total absorption spectrometer to detect the transmitted neutrons. Biasing the spectrometer towards high neutron momenta together with the strongly-peaked momentum spectrum of the beam gave relatively good momentum resolution. Measurements were made at mean momenta of 12, 13, 18 and 26.5 GeV/c. Results are presented and the cross sections for nuclei are compared with theoretical predictions.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/33550/1/0000050.pd
