Jornadas de Poéticas de la Literatura Argentina para Niños (2 : 2010 : La Plata). Literatura argentina e infancia

Nos hemos propuesto publicar las ponencias seleccionadas para ser leídas en las II Jornadas de Poéticas de la Literatura argentina para niños que tuvieron lugar en el Colegio Nacional "Rafael Henández" de la ciudad de La Plata, el 5 de noviembre de 2010 con el fin de poner en circulación la producción teórico-crítica de colegas argentinos interesados en el campo de la literatura infantil argentina.

Escrituras de lo real : César Aira y Arturo Carrera

El trabajo no realiza un estudio comparatístico sino que explora las relaciones móviles y productivas entre dos poéticas que son afines y son producto de dos autores importantes en la literatura argentina contemporánea. De esta manera, los conceptos de vanguardia y tradición nos permiten dar un marco para examinar el estatuto experimental de estas escrituras a través de motivos como el viaje, la experiencia subjetiva del espacio, del tiempo y la cultura.

Laser pulse shaping with liquid crystals (1982)

In this paper we report a new method of laser pulse shaping by the use of liquid crystals as non linear materials. The basis of this method is similar to the one reported by us for an hybrid optical bistable device, but with a different electronic circuitry and feedback.

Optical memory with TNLC devices (1982)

In this paper we describe a twisted nematic liquid crystal (TNLC) device structure with optical feedback capable of bistable operation and optical memory. Its structure is the conventional one as employed in hybrid optical bistability.

Effects of static stretching following a dynamic warm-up on speed, agility and power

Static stretching prior to sport has been shown to decrease force production in comparison to the increasing popularity of dynamic warm-up methods. However some athletes continue to use a bout of static stretching following dynamic methods. The purpose of this study was to investigate the effects on speed, agility and power following a period of additional static stretching following a dynamic warm-up routine. Twenty-five male University students who participated in team sports performed two warm-up protocols concentrating on the lower body one week apart through a randomised cross over design. The dynamic warm-up (DW) protocol used a series of specific progressive exercises lasting 10 minutes over a distance of 20m. The dynamic warm-up plus static stretching (DWS) protocol used the same DW protocol followed by a 5 minute period during which 7 muscle groups were stretched. Following each warm-up the subjects performed a countermovement vertical jump, 20m sprint and Illinois agility test, 1 minute apart. The results demonstrated no significant differences in speed, agility and jump performance following the two protocols DW and DWS. The study concludes that performing static stretching following a dynamic warm-up prior to performance does not significantly affect speed, agility and vertical jump performance.

Determining factors of the innovative behavior of cooperatives: an analysis of the case of Castilla y León

Cooperatives have a long historical experience in the Spanish economy and have demonstrated their ability to compete against traditional firms in the market. To maintain this capability, while taking advantage of the competitive advantages associated with their idiosyncrasies as social economy enterprises, they should take into consideration that the economy is increasingly globalized and increasingly knowledge-based, especially with regards to technological content. As a consequence, the innovative capacity appears to be a key aspect in order to be able to challenge competitors. This article characterizes the innovative behavior of cooperatives in the region of Castile and Leon and analyses the internal and external factors affecting their innovative performance, based on data from a survey of 581 cooperatives. The results of the empirical analysis, which is performed by multivariate binary logistic regression on various types of innovation, lead us to identify the size of the organizations, the existence of planning, the R & D activities and the human capital as the main determining factors.

Mediciones in situ de TS de diversas especies a finales del invierno de 1998. Crucero BIC Humboldt 9808-09

Se efectuaron mediciones de TS (Fuerza de Blanco, Target Strenght) durante los 108 lances de comprobación de ecotrazos realizados por el BIC Humboldt en el marco del Crucero 9808-09 de Evaluación Hidroacústica de Recursos Pelágicos. Se consideran para el análisis únicamente aquellos lances donde más del 90% de la captura perteneció a una sola especie. Los factores b20 de la ecuación de TS (TS=20 log L - b20) que han sido determinados, las cuales deberán ser considerados como provisionales, son las siguientes: Pez cinta (Trichiurus lepturus) = 70,95 (120 kHz); Vinciguerria o pez linterna (Vinciguerria lucetia pacifici) = 83,29 (120 kHz); Samasa (Anchoa nasus) = 86,57 (120 kHz); Caballa (Scomber japonicus) = 83,09 (120 kHz); Pez cinta (Trichiurus lepturus) = 71,41 (38 kHz); y Vinciguerria o pez linterna (Vinciguerria lucetia pacifici)= 82,04 (38kHz).
