    Schumann\u27s Dichterliebe: A Revelation of a Great Composer\u27s Life and Passion

    Get PDF
    From a young age, German composer Robert Schumann’s passions for music, drama, and literature were evident. Through personal tragedies and an uncertain career path, these talents guided Schumann into a successful career in composition. Childhood interests in literature and the influence of German author Jean Paul Richter had a profound effect on Schumann’s compositional style. His view that music was the most effective aesthetic vehicle for expression was combined with Jean Paul’s definition of Romanticism to create a philosophy of music Schumann would come to live by. In the face of poverty, commercial failure, and artistic frustration with piano composition, Schumann took up a new compositional medium in the form of songwriting. The resulting Year of the Song in 1840 produced over 120 vocal compositions, including the Dichterliebe song cycle. This masterpiece of German Lieder and Romantic song cycle tradition is widely regarded as one of the greatest ever written. Dichterliebe, song settings of poems by German poet Heinrich Heine, displays Schumann’s distinctive ability to set text to music. His use of tonal relationships utilizes modality to guide the narrative along its trajectory. His affinity for romantic irony is evident in the creative ways in which he expresses this literary concept musically. Finally, Schumann’s unique talents in creating complex piano arrangements to provide musical imagery and aesthetic atmosphere set this work apart from others of the time. This paper will explore the life of Robert Schumann, how his passions, interests, and heartaches shaped his compositional style, examine his techniques and unique approach to text painting, and discuss considerations for the performer of Dichterliebe

    Analytical and experimental study of FRP honeycomb sandwich panels with sinusoidal core

    Get PDF
    Fiber reinforced plastic (FRP) composite materials and structures have been increasingly used in highway bridge applications. Recent applications have demonstrated that FRP honeycomb sandwich panels with sinusoidal core can be effectively and economically used for highway bridge deck systems. In this study, analytical and experimental characterizations are presented for a FRP honeycomb panel with sinusoidal core geometry in the plane and extending vertically between face laminates. To verify the accuracy of the a closed-form solution, several honeycomb sandwich beams with sinusoidal core waves either in the longitudinal or transverse directions are tested in bending and torsion. Also, a deck panel is tested under both symmetric and asymmetric patch loading. Finite element models are further developed to simulate the actual sandwich geometry and also to simplify the structure as an equivalent three-layer laminate. The explicit and FE predictions are compared with experimental results. The present analysis and characterization procedures can be used in design applications and optimizations of honeycomb structures

    Fundamental Properties of Active Galaxies: Distances and Black Hole Masses of Nearby Seyferts

    The past 20 years of observations have revealed correlations between supermassive black holes (SMBHs) and large scale galaxy properties. These correlations are generally interpreted to be the signature of coevolution between galaxies and black holes, therefore accurate measurements of the properties on which these correlations are constructed is crucial for understanding galaxy-black hole evolution over cosmic time. We first present HI 21 cm spectroscopy for 31 AGN host galaxies with direct black hole mass (MBH) measurements from reverberation mapping (RM), 12 of which are the first published detections at 21 cm. We measure emission-line fluxes, widths, and recessional velocities from which we derive HI mass, gas mass (MGAS), and redshift. Combining MGAS with stellar mass (MSTARS) allows the baryonic mass (MBARY) to be estimated. We then combine the emission line measurements with Hubble Space Telescope and ground-based optical and near-infrared images to measure Tully-Fisher distances to 24 of the 31 galaxies, 14 of which are the first reported distances independent of redshift. We estimate dynamical mass (MDYN) within the HI radius, and a comparison to MBARY constrains the dark matter mass (MDM). We find significant correlations between MBH and MBARY, MDYN, and MDM, suggesting black hole-galaxy connections on scales larger than commonly considered. Finally, we present preliminary results of dynamical modeling of the broad line regions (BLRs) of five AGNs, four of which are the first reported. Direct modeling of the continuum light curve and broad emission lines yields constraints on BLR geometry and kinematics in addition to constraints on MBH that do not depend on the scale factor required by traditional RM methods. This work presents measurements of fundamental properties of RM AGNs and their host galaxies that may serve as important tools for future analyses devoted to furthering our understanding of black hole-galaxy coevolution

    Bear Lake’s natural watershed is made up of relatively low mountains covered with sagebrush at lower elevations and southern exposures and fir-aspen forests at higher elevations and northern exposures. The basin is traversed by the Bear River that begins high in the Unita Mountains and flows through Utah, Idaho, and Wyoming before feeding the Great Salt Lake. The Bear River is the major river in the watershed but does not directly feed Bear Lake...

It is bordered on the east by Wyoming, on the north by Idaho (with the southern half of Bear Lake extending into Utah), on the west by Weber and Morgan counties and the Wasatch National Forest, and on the south by Summit County

    Learn it, Live it, Teach it, Embed it: Implementing a whole school approach to foster positive mental health and wellbeing through Positive Education

    Get PDF
    Schools provide unique environments for the implementation of interventions to support the mental health and wellbeing of young people. While promising as an intervention setting, the school system is inherently complex, and any successful intervention or programme must account for, and adapt to, such complexity. Whole-school approaches that comprise multi-components and promote collaborative and collective action across the school system appear promising for accounting for these complexities. This paper reports the updated implementation processes of one whole-school approach, the Geelong Grammar School Applied Model for Positive Education, for fostering positive mental health and wellbeing among the school community. Drawing upon existing frameworks and from successes observed in the fields of Social and Emotional Learning, mental health prevention, and health promotion, adapted to meet the goals of Positive Education, we propose four interconnecting, cyclical processes; Learn it, Live it, Teach it, Embed it. In combination, these processes assist schools in designing and reviewing ongoing implementation. This study extends the literature to date by synthesising organisational, systems change, education, and anecdotal evidence to identify barriers to implementation and subsequent outcomes of missed, or poorly executed processes. While schools will be unique in factors such as context, specific needs, and available resources, it is envisaged that reporting these processes and potential barriers to success may assist schools with their own future implementation endeavours

    Many bird species use Bear Lake seasonally or during migrations. Herons, egrets, sandpipers, rails, pelicans, geese, coots, grebes, Tundra swans and osprey are common visitors throughout the year. During the spring months of April through June the area becomes the primary breeding grounds for the burrowing owl, gray flycatcher, long-billed curlew, peregrine falcon, and the black-throated gray warbler. Early in the summer months, several species of mergansers and diving ducks converge on the rocky shorelines to fish as the newly hatched Bear Lake sculpin occupy shallow waters during this period. During winter the area becomes critical habitat for the American eagle and Swainson’s hawk...
