Unlike some other major composer-pianists (Franz Liszt and Alexander Scriabin being the most notable examples), Sergei Rachmaninov did not experience any dramatic changes in his compositional style; one can, however, notice certain stylistic differences between piano works composed during different periods of his long creative life. This dissertation argues that a clear evolution of Rachmaninov's pianistic style through his three creative periods can be traced by examining a selection of his compositions, from his first significant cycle for piano, 5 Marceaux de fantaisie, Op. 3 (1892), all the way through to his last piano work, a transcription of P.I.Tchakovsky's Lullaby, Op. 16, No. 1 (1941). Rachmaninov's life as a composer can be divided into three periods. His early period was ended abruptly by the disastrous premiere ofhis First Symphony in 1897, which caused a deep psychological crisis in the life of the young composer. Piano works of this period are often characterized by relatively simple homophonic texture, when Rachmaninov was clearly influenced by some of his Russian predecessors, most notably Tchaikovsky. His second and most productive period, also known as the period of"Russian maturity," started in 1900, when he began working on the Second Suite for two pianos, Op. 17, and the Second Concerto, Op. 18; this phase ended with the Russian Bolshevik revolution of 1917. Works of this time exhibit a mature style of piano writing, with rich, virtuosic - often considered excessive by many critics - texture and ever-increasing use of chromatic harmonies. Rachmaninov's works of the third period are limited in number owing to the composer's preoccupation with a career as pianist. Original works for piano now give way to revisions of earlier compositions and transcriptions: Rachmaninov's piano writing becomes more efficient and economical without losing any of its virtuosic brilliance. This dissertation project examines in detail, over the course of three piano recitals, a variety of works composed during the "Russian maturity" period, from several Preludes from Op. 23 (1903), the first major cycle for solo piano of the period, to 9 Etudes-Tableaux, Op.39 (1917), the last one; the early period is represented by 3 of 5 Marceaux defantaisie, Op. 3 (1892), while the late period is shown through several piano transcriptions and revised versions of the remaining 2 pieces from Op. 3.

La industria de Maquinaria Agrícola de origen Nacional ha acompañado a lo largo de la historia el desarrollo económico y social de la Argentina. Desde fábricas de características artesanales ubicadas en la región Pampeana, nuestro país ha sabido durante los años 1950 a 1980 ser un precursor en materia de cosechadoras que ofrecían respuestas a quienes comenzaban a mecanizar todas las actividades agrícolas. Sin embargo, durante las décadas siguientes, diferentes inconvenientes macroeconómicos y propios de la globalización han cambiado el panorama de la fabricación de cosechadoras. En este contexto, el objetivo del presente trabajo es evaluar dicho mercado en el período 1990-2010. La estrategia metodológica se basó en el análisis de mercado con información secundaria proveniente de organismos oficiales. Entre los principales resultados se pueden citar la estructura de la oferta, de la demanda, del producto y la comercialización.

Conocer la historia de la propia profesión es uno de los signos de identidad que caracteriza a los grupos sociales. Los educadores matemáticos españoles están comenzando a considerarse como grupo profesional diferenciado, con necesidades formativas propias y unas condiciones de trabajo específicas bien definidas, que necesitan de infraestructura adecuada. La caracterización de esta profesión es resultado de un proceso lento de profundización teórica e implementación práctica llevado a cabo a lo largo de muchos años, con avances y retrocesos, e interconectado con los recientes cambios sociales y políticos ocurridos en España. Por ello, constituir una comunidad de educadores matemáticos, formada por profesionales autónomos y críticos, socialmente eficaces, es una tarea lo suficentemente importante como para necesitar el esfuerzo de todos.
