Into the Bends of Time and Musical Forces in Jazz: Group Interaction and Double-time in “My Foolish Heart” as performed by the Bill Evans Trio with Scott LaFaro and Paul Motian.

Into the Bends of Time is a 40-minute work in seven movements for a large chamber orchestra with electronics, utilizing real-time computer-assisted processing of music performed by live musicians. The piece explores various combinations of interactive relationships between players and electronics, ranging from relatively basic processing effects to musical gestures achieved through stages of computer analysis, in which resulting sounds are crafted according to parameters of the incoming musical material. Additionally, some elements of interaction are multi-dimensional, in that they rely on the participation of two or more performers fulfilling distinct roles in the interactive process with the computer in order to generate musical material. Through processes of controlled randomness, several electronic effects induce elements of chance into their realization so that no two performances of this work are exactly alike. The piece gets its name from the notion that real-time computer-assisted processing, in which sound pressure waves are transduced into electrical energy, converted to digital data, artfully modified, converted back into electrical energy and transduced into sound waves, represents a “bending” of time.

The Bill Evans Trio featuring bassist Scott LaFaro and drummer Paul Motian is widely regarded as one of the most important and influential piano trios in the history of jazz, lauded for its unparalleled level of group interaction. Most analyses of Bill Evans’ recordings, however, focus on his playing alone and fail to take group interaction into account. This paper examines one performance in particular, of Victor Young’s “My Foolish Heart” as recorded in a live performance by the Bill Evans Trio in 1961. In Part One, I discuss Steve Larson’s theory of musical forces (expanded by Robert S. Hatten) and its applicability to jazz performance. I examine other recordings of ballads by this same trio in order to draw observations about normative ballad performance practice. I discuss meter and phrase structure and show how the relationship between the two is fixed in a formal structure of repeated choruses. I then develop a model of perpetual motion based on the musical forces inherent in this structure. In Part Two, I offer a full transcription and close analysis of “My Foolish Heart,” showing how elements of group interaction work with and against the musical forces inherent in the model of perpetual motion to achieve an unconventional, dynamic use of double-time. I explore the concept of a unified agential persona and discuss its role in imparting the song’s inherent rhetorical tension to the instrumental musical discourse.

Evans functions for integral neural field equations with Heaviside firing rate function

In this paper we show how to construct the Evans function for traveling wave solutions of integral neural field equations when the firing rate function is a Heaviside. This allows a discussion of wave stability and bifurcation as a function of system parameters, including the speed and strength of synaptic coupling and the speed of axonal signals. The theory is illustrated with the construction and stability analysis of front solutions to a scalar neural field model and a limiting case is shown to recover recent results of L. Zhang [On stability of traveling wave solutions in synaptically coupled neuronal networks, Differential and Integral Equations, 16, (2003), pp.513-536.]. Traveling fronts and pulses are considered in more general models possessing either a linear or piecewise constant recovery variable. We establish the stability of coexisting traveling fronts beyond a front bifurcation and consider parameter regimes that support two stable traveling fronts of different speed. Such fronts may be connected and depending on their relative speed the resulting region of activity can widen or contract. The conditions for the contracting case to lead to a pulse solution are established. The stability of pulses is obtained for a variety of examples, in each case confirming a previously conjectured stability result. Finally we show how this theory may be used to describe the dynamic instability of a standing pulse that arises in a model with slow recovery. Numerical simulations show that such an instability can lead to the shedding of a pair of traveling pulses.

Evaluación in vitro de hongos nativos antagonistas de Moniliophthora rereri (Cif. & Par., Evans et al.,) en el cultivo de cacao (Theobroma cacao L.)

El cacao es afectado por una diversidad de microorganismos patógenos, entre ellos el hongo Moniliophthora roreri (Cif. & Par., Evans et al.,) causante de la moniliasis, que es una de las enfermedades de mayor importancia de este cultivo. El uso irracional de plaguicidas sintéticos para el manejo de esta enfermedad ha generado problemas al agroecosistema y la salud humana, por lo que se está demandando el uso de alternativas agroecológicas. En este contexto, el objetivo principal de esta investigación fue generar información acerca de la capacidad antagónica in vitro mostrada por hongos nativos contra la moniliasis del cacao. Se recolectaron muestras de suelo, hojas, corteza, frutos sanos y enfermos en tres zonas cacaoteras de Nicaragua para la caracterización morfológica del patógeno y de los potenciales microorganismos antagonistas. Las pruebas de antagonismo “in vitro” se realizaron a través de la técnica del cultivo dual. Se evaluó el crecimiento radial del patógeno y de los antagonistas, el porcentaje de inhibición del crecimiento radial (PICR) del patógeno y la capacidad de control biológico de los hongos antagonistas. Se probaron cuatro técnicas para la conservación de los hongos antagonistas. Se obtuvieron cuatro aislados del patógeno M. roreri y 17 aislados de hongos antagonistas. El PICR del patógeno ejercida por aislados del antagonista Trichoderma varió de 40.13% a 46.77%, en los aislados del antagonista Paecilomyces el PICR osciló entre 59.38% y 67.43%, en el único aislado del antagonista Clonostachys el PICR fue de 62.33%-67.22%. Los 17 aislados se ubicaron en las clases 1, 2 y 3 de la escala de valoración de antagonismo. La mejor técnica de conservación de hongos antagonistas y de M. roreri fue la de conservación con glicerol. Los resultados de este estudio indican que en el agroecosistema de cacao existen microorganismos nativos que tienen potencial para ser usados como agentes de control biológico del patógeno M. roreri.

Desenvolvimento de coleções no sistema de bibliotecas da UFES: comparativo entre os modelos teóricos de Evans e Baughman e proposta de adequação ao modelo de Evans

As Bibliotecas Universitárias (BUs) constituem unidades de informação, cujo objetivo principal é fornecer materiais informacionais aos diversificados atores que compõem o espaço universitário. No entanto, formar e desenvolver coleções nessas unidades de informação pode representar uma missão instigante e desafiadora. Isso porque, as coleções que formam os acervos das BUs não são estáticas, devendo estar em constante crescimento no intento de atender as propostas pedagógicas da universidade, viabilizando o trabalho de ensino, pesquisa e extensão. Considerando as complexidades existentes no processo de formação e desenvolvimento de coleções, este estudo objetiva comparar as atividades realizadas em prol da formação e desenvolvimento de coleções do SIB/UFES, de acordo com os modelos teóricos de Evans e Baughman, propondo alternativas de melhoria conforme a proposta dos modelos, com vistas a garantir a adequação das coleções às exigências e necessidades dos usuários da coleção. Para tanto, através de pesquisa bibliográfica, documental e diagnóstico, propõe-se uma reflexão teórica acerca do desenvolvimento de coleções e sua relação com o SIB/UFES. Apresenta as características centrais dos modelos teóricos de Evans e Baughman. Compara as características desses modelos com a realidade do SIB/UFES. Por fim, os resultados confirmaram haver necessidade de adequação ao modelo holístico, consolidando uma gestão sistêmica, bem como a construção de uma política de desenvolvimento de coleções, objetivando fundamentar e nortear todas as ações em prol da constante adequação da coleção às necessidades demandadas pela comunidade universitária.

La reproducción asistida ante el Tribunal Europeo de Derechos Humanos: de Evans c. Reino Unido a Parrillo c. Italia

Pese a que la mayoría de ordenamientos europeos regulan las técnicas de reproducción asistida, ello no reduce la diversidad existente entre los estados miembros por lo que respecta a cuestiones especialmente sensibles, tales como las condiciones de acceso estas técnicas; el uso del diagnóstico genético preimplantacional para evitar que un hijo sea portador de una determinada enfermedad genética; el recurso a técnicas heterólogas o con gametos donados; los efectos que deben otorgarse a los acuerdos de gestación por sustitución celebrados en el extranjero; o el destino de los embriones sobrantes de un ciclo de fecundación "in vitro". Las diferentes respuestas a estas cuestiones dan cuenta de la variedad de aproximaciones de los estados en la materia. Esta diversidad se ha visto fomentada, en el momento actual por el mal llamado "turismo reproductivo", un fenómeno que, como se analiza críticamente en este trabajo, se ha visto avalado por el propio TEDH.
