Guided composition: a performer’s guide to an original work by composer Lance Hulme with an exploration of the interaction and collaboration between composer and performing artist

For centuries composers have worked with performers to assist in the realization and expression of their musical ideas. As modern composers produce new works of music, performers are needed to contribute their expertise in producing accurate and idiomatic parts for their instruments. Lance Hulme composed his sonata for violin and piano, Reel to Real, in 2016 in consultation with me for the violin part. I assisted him with revisions, interpretations, and technical recommendations through numerous stages leading to the final score. Original drafts of each movement are accompanied by critique and editorial commentary, giving insight into the collaborative relationship. A performance edition of the violin part with pedagogical commentary is included. The performance edition is based on the original manuscript with emphasis on clarity of the composer’s intent and pedagogical and technical solutions to the challenges it contains. Bowings, fingerings, and string recommendations are indicated along with justifications for their choice. This edition and commentary provide a foundation from which future study and performance of the work may begin

The Role of Multiple Sclerosis as a Risk Factor for the Development of Osteoporosis

Background: Osteoporosis is the most common bone disease in the United States, and it is particularly common among women with multiple sclerosis (MS). However, despite this association, the temporal relationship between these two conditions has not been previously studied. Data from the Women’s Health Initiative provides a unique opportunity to examine the risk of developing osteoporosis over time in individuals diagnosed with MS. Objective: The purpose of this study is to refine the relationship between MS and osteoporosis, clarifying the impact of environmental and pharmacologic factors on each condition, as well as addressing treatment and preventative efforts for a patient population at a greater potential risk for osteoporosis. Methods: The study sample, derived from the Women’s Health Initiative, included 449 women who reported an MS diagnosis at baseline and 161,359 women without MS who comprised a control group. Baseline measures of self-reported osteoporosis, age, smoking status, steroid and anti-inflammatory use, and supplementary as well as dietary calcium and vitamin D were compared. MS patients reporting osteoporosis at baseline were removed, resulting in 355 women with MS to monitor for time to incident osteoporosis. Survival analyses were performed on follow-up data gathered annually between 1993 and 2005 to factor out significant associations of additional factors. Proportions of participants on osteoporosis-related medications as well as latency to use were compared between the multiple sclerosis and control cohorts. Results: At baseline, women with MS are nearly three times as likely to report osteoporosis (p Conclusions: A higher prevalence of osteoporosis at baseline suggests MS may significantly increase the risk of osteoporosis in premenopausal women. In contrast, environmental and pharmacologic variables appear to have a more significant role in the post-menopausal population. While osteoporosis was treated similarly between both groups, the point for intervention or prevention of osteoporosis in MS patients may be earlier in the disease course

Developing a reduced consumer-led lexicon to measure emotional response to beer

Previous researchers have recently recommended and utilised consumer-led lexicons to measure emotional response. This study further advances this approach by 1) making the lexicon generation process more efficient by using consumer focus groups as opposed to individual consumer interviews and 2) decreasing the number of responses required from each consumer by reducing the lexicon to categories of similar terms. In response to 10 lager samples which were manipulated in order to control selected sensory properties, focus groups generated a lexicon of 44 emotion terms. This lexicon was reduced to 12 distinct emotion categories using linguistic checks and cluster analysis. Naïve beer consumers (n = 113) used these 12 emotion categories to rate their emotional response to the 10 samples. The reduced consumer-led lexicon was validated through its ability to discriminate across samples as well as show differences in emotional response between genders and age groups. The 12 emotion categories were found to discriminate well between samples, although a number of categories grouped samples similarly. However, differences in responses to otherwise comparable emotion categories were identified between genders and age groups, highlighting the importance of including all emotion categories so as to not over-reduce the lexicon and risk missing out on valuable emotion data

Socializing One Health: an innovative strategy to investigate social and behavioral risks of emerging viral threats

In an effort to strengthen global capacity to prevent, detect, and control infectious diseases in animals and people, the United States Agency for International Development’s (USAID) Emerging Pandemic Threats (EPT) PREDICT project funded development of regional, national, and local One Health capacities for early disease detection, rapid response, disease control, and risk reduction. From the outset, the EPT approach was inclusive of social science research methods designed to understand the contexts and behaviors of communities living and working at human-animal-environment interfaces considered high-risk for virus emergence. Using qualitative and quantitative approaches, PREDICT behavioral research aimed to identify and assess a range of socio-cultural behaviors that could be influential in zoonotic disease emergence, amplification, and transmission. This broad approach to behavioral risk characterization enabled us to identify and characterize human activities that could be linked to the transmission dynamics of new and emerging viruses. This paper provides a discussion of implementation of a social science approach within a zoonotic surveillance framework. We conducted in-depth ethnographic interviews and focus groups to better understand the individual- and community-level knowledge, attitudes, and practices that potentially put participants at risk for zoonotic disease transmission from the animals they live and work with, across 6 interface domains. When we asked highly-exposed individuals (ie. bushmeat hunters, wildlife or guano farmers) about the risk they perceived in their occupational activities, most did not perceive it to be risky, whether because it was normalized by years (or generations) of doing such an activity, or due to lack of information about potential risks. Integrating the social sciences allows investigations of the specific human activities that are hypothesized to drive disease emergence, amplification, and transmission, in order to better substantiate behavioral disease drivers, along with the social dimensions of infection and transmission dynamics. Understanding these dynamics is critical to achieving health security--the protection from threats to health-- which requires investments in both collective and individual health security. Involving behavioral sciences into zoonotic disease surveillance allowed us to push toward fuller community integration and engagement and toward dialogue and implementation of recommendations for disease prevention and improved health security

Radiocarbon Dating of Silica Sinter and Postglacial Hydrothermal Activity in the El Tatio Geyser Field

The El Tatio geothermal field in the Chilean Altiplano contains hydrothermal silica sinter deposits overlaying glacial and volcanic units, providing an opportunity to constrain the timing of deglaciation and volcanic activity in an area with sparse absolute chronologies. We obtained 51 new radiocarbon ages and delta C-13 values on the organic material trapped in these sinter deposits. Based on the delta C-13 values, we exclude 29 samples for possible contamination with bacterial mats that incorporate old carbon. We infer that hydrothermal activity initiated similar to 27 ka ago and has been nearly continuous ever since. The ages of the oldest sinter deposits coincide with ages of moraines that stabilized after the most recent deglaciation. Whereas late Pleistocene sinters are broadly distributed in the field, Holocene deposits are found around active hydrothermal features. Although recent volcanism is absent in the vicinity of El Tatio, persistent hydrothermal discharge implies a long-lived magmatic heat source.National Science Foundation (NSF) EAR1724986 Comisión Nacional de Investigación Científica y Tecnológica (CONICYT) CONICYT FONDEF 15090013 "Centro de Excelencia en Geotermia de Los Andes," CEGA FONDECYT Postdoctoral Grant (Comisión Nacional de Investigación Científica y Tecnológica) 3170007 ICM grant "Millennium Nucleus for Metal Tracing Along Subduction" United States Geological Survey USGS Geothermal Energy Projec
