Tracing Neoclassical Influences in selected solo and chamber music for the clarinet

The musical period of Neoclassicism began in the 1920's, between the first and second world wars. It was initiated by French composers and eventually spread to other countries. One of the most important themes to emerge from the movement was to escape from the formless, rather emotional music of the Romantic era and instead, emphasize balance, order, objectivity and clarity in musical form. Many popular clarinet repertoires are enjoyed by performers and listeners because the music is enjoyable to play and easy to listen to. In particular, classically influenced clarinet music is quite interesting because it features musical elements from both the past and contemporary musical styles. For instance, some composers have integrated preexisting, more traditional styles of composition with lighter styles of modern culture such as popular music and Jazz. It is difficult to discover purely neoclassical clarinet repertoires even though many composers created their pieces during the neoclassical era. What we most commonly find are both neoclassical and non-neoclassical influences in compositions from that time period. Thus, I aim to trace the influence of neoclassicism in selected clarinet repertoires that exist today. It is my hope that increased awareness and knowledge about accessible clarinet music may encourage the general public to develop a deeper interest in a wider sphere of clarinet music, beyond what is considered popular today. The works performed and discussed in this dissertation are the following: (Recital I) Duo Concertante by Darius Milhaud; Sonata by Leonard Bernstein; Sonata for Two Clarinets by Francis Poulenc; Duos for Flute and Clarinet, Op. 34 by Robert Muczynski; Dance Preludes by Witold Lutoslawski, (Recital II) Sonatine by Arthur Honegger; Time pieces by Robert Muczynski; Suite for Clarinet, Violin and Piano by Darius Milhaud; Sonate for Clarinet, Flute and Piano by Maurice Emmanuel; Tarantelle for Flute, Clarinet and Piano, Op. 6 by Camille Saint-Saëns, (Recital III) Sonatina by Joseph Horovitz; Suite from L'histoire du Soldat for Clarinet, Violin and Piano by Igor Stravinsky; Contrasts for Clarinet, Violin and Piano by Béla Bartók The recitals that took place on December 1, 2012 and on April 25, 2013 were performed in the Ulrich Recital Hall of the Clarice Performing Arts Center in College Park, Maryland. The recital that took place on November 2, 2013 was performed at the Gildenhorn Recital Hall of the same performing arts center.

Developing Quantitative Methodologies for the Digital Humanities: A Case Study of 20th Century American Commentary on Russian Literature

Using scientific methods in the humanities is at the forefront of objective literary analysis. However, processing big data is particularly complex when the subject matter is qualitative rather than numerical. Large volumes of text require specialized tools to produce quantifiable data from ideas and sentiments. Our team researched the extent to which tools such as Weka and MALLET can test hypotheses about qualitative information. We examined the claim that literary commentary exists within political environments and used US periodical articles concerning Russian literature in the early twentieth century as a case study. These tools generated useful quantitative data that allowed us to run stepwise binary logistic regressions. These statistical tests allowed for time series experiments using sea change and emergency models of history, as well as classification experiments with regard to author characteristics, social issues, and sentiment expressed. Both types of experiments supported our claim with varying degrees, but more importantly served as a definitive demonstration that digitally enhanced quantitative forms of analysis can apply to qualitative data. Our findings set the foundation for further experiments in the emerging field of digital humanities.

Control microbiano de la chinche del tallo del arroz, Tibraca limbativentris Stal. 1860 (Hemiptera: Pentatomidae) con hongos entomopatógenos

El cultivo del arroz es una de las principales actividades productivas en el Nordeste Argentino, el cual se ve afectado por diferentes plagas que reducen su rendimiento y calidad. Entre ellas, la chinche del tallo, Tibraca limbativentris es una de las plagas principales. Para su control, el uso de agroquímicos es generalizado, por su conveniencia y eficiencia. Sin embargo, el mal uso de los productos fitosanitarios está ocasionando problemas al ambiente, lo que lleva a la búsqueda de nuevas tecnologías, reduciendo al mínimo los riesgos al ambiente y a la salud humana en particular. En el presente estudio se evalúa el uso de hongos entomopatógenos como una alternativa para reducir la población de T. limbativentris. Se realizaron muestreos en diversas zonas arroceras en búsqueda de cepas nativas de hongos entomopatógenos, lográndose aislar 11 cepas de adultos de esta chinche. A través de bioensayos se evaluaron 32 cepas de hongos entomopatógenos sobre adultos y dos de ellas causaron la muerte del 100 por ciento de los mismos. Se seleccionó la cepa Ma 72 de Metarhizium anisopliae y se evaluó la compatibilidad con diversos herbicidas usados frecuentemente en la producción de arroz. Se logró producir la cepa sobre diversos sustratos en fermentación en medio sólido (FMS4), destacándose el arroz blanco quebrado, sobre el cual se obtuvo 3,8 x 109 conidios/gr de sustrato. Se evaluaron diferentes tipos de formulaciones experimentales durante 100 días y la viabilidad se mantuvo sólo bajo condiciones de refrigeración (6 °C). Se evalúo la eficiencia de diversos formulados experimentales sobre adultos de T. limbativentris en condiciones de invernáculo, logrando un control satisfactorio (entre 56 y 77 por ciento de mortalidad) a los 30 días. Se concluyó que la cepa Ma 72 de M. anisopliae sería una herramienta promisora para su empleo en el control microbiano de la chinche del tallo T. limbativentris y podrían incluirse como parte de un programa de Manejo Integrado de plagas en arroz
