A shape-based decomposition of the yield adjustment term in the arbitrage-free Nelson and Siegel (AFNS) model of the yield curve

The appealing feature of the arbitrage-free Nelson-Siegel model of the yield curve is the ability to capture movements in the yield curve through readily interpretable shifts in its level, slope or curvature, all within a dynamic arbitrage-free framework. To ensure that the level, slope and curvature factors evolve so as not to admit arbitrage, the model introduces a yield-adjustment term. This paper shows how the yield-adjustment term can also be decomposed into the familiar level, slope and curvature elements plus some additional readily interpretable shape adjustments. This means that, even in an arbitrage-free setting, it continues to be possible to interpret movements in the yield curve in terms of level, slope and curvature influences. © 2014 © 2014 Taylor & Francis.

Uma descrição sonora contemporânea do imagético tradicional armorial como subsídio para abordagens interpretativas do ciclo de canções “Visagem” de Nelson Almeida

This study suggests sonorous ambiences from the propose of images configured according to the description in “A Visagem da Moça Caetana” by Ariano Suassuna in order to create individual sonorous possibilities that may help musicians to play the piece. The cycle, composed in 1996 (for voice, viola, cello, bass clarinet/clarinet), is formed by three untitled songs. Its text is an excerpt from the “Folheto XLIV”, from the Romance d’A Pedra do Reino e o príncipe do sangue do vai-e-volta, and describes a sentence of death illustrated by symbols of the Armorial imagery, with neologisms and the peculiar accent from the Sertão in northeast Brazil. In addition to the analysis of technical difficulties to play, this study informs interpreters of the sonorous timbre and texture used by Nelson Almeida to describe tradition through contemporary musical language. The metaphors and transgressions of reason in Suassuna’s book were explored to create three image compositions so that they may lead interpreters to the sonorous description of the inanimate objects and the affections to which the poetry refers, expanding any technical-interpretative indications limited by musical notation. This research used the Visagem scores, the literature on the theme, discussions with the musicians that played the piece, interviews with Almeida, and composers’ reports. To illustrate the theory, the three images are available, printed as woodcut in cordel literature.

Effect of reading sport chronicles on the perception of justice and the predisposition to protest actions in soccer

In this study three chronicles from national newspapers (one generalist and two sport press) were analyzed. The chronicles belong to Spain’s soccer final of the King’s Cup in 2014. The aim of the study was to know if there was any influence on the readers’ perception of justice and consequently if this influence could cause a particular predisposition to participate in acts of protest. 462 university students participated. The results showed that different chronicles caused differences in the perception of justice depending on the chronicle read. However, a clear influence on the willingness to participate in acts of protest was not obtained. These results should make us think about the impact of sport press and its influence, and to be aware of the indirect responsibility of every sector on the antisocial behaviors generated by soccer in our country.

“GEOGRAFIA E IDEOLOGIA”: O PAPEL DE NELSON WERNECK SODRÉ PARA A GEOGRAFIA

A geografia crítica encontrou em Nelson Werneck Sodré uma de suas primeiras expressões. No final da década de 1970, quando a Geografia brasileira, especialmente a acadêmica era dominada pela “Escola” francesa e quando o neopositivismo já grassava no campo do planejamento econômico-territorial, este autor aparece como um dos pioneiros a exigir a reflexão crítica do fazer geográfico. Este trabalho procura resgatar o papel político cumprido por “Introdução à Geografia: Geografia e Ideologia” em relação ao movimento crítico que ganhou maior força nos anos de 1980-90. Sua crítica recai diretamente sobre a Geografia enquanto instrumento geopolítico primordial dos países centrais, numa construção que a coloca como um dos principais veículos da colonização e, portanto, do imperialismo. O método geográfico é acusado e deslindado na exposição da obra como o maior responsável pela debilidade da Geografia em assumir seu devido papel no movimento social. A exclusão da abordagem historicizada, teria tornado a Geografia um instrumento do poder imperialista retirando dela o caráter científico e a colocando na condição de ideologia. O movimento crítico alcançou um patamar que começa a requisitar sua devida avaliação e é, nesse sentido, que se desenvolve esta pesquisa que, aqui, expressa parte de seus resultados.
