Crítica y poesía. Elementos para una tradición

Este ensayo estudia las operaciones epistemológicas actuantes en la crítica argentina contemporánea de poesía, tomando en cuenta el estatuto teórico-filosófico de su discurso. Para ello, postula una tradición emergente en las últimas décadas del siglo XX, desde la constitución de un texto fundacional: el ensayo de Noé Jitrik titulado "Alturas de Machu Picchu. Una marcha piramidal a través de un discurso poético incesante". Posteriormente, se muestra en dos críticos destacados de una promoción posterior -Cristina Piña y Daniel Freidemberg- la coexistencia de tendencias opuestas en las elecciones estéticas, propias de las poéticas de los años sesenta y prolongadas hasta los ochenta, pero con la común característica del productivo procesamiento de la moderna teoría literaria.

Faster group operations on elliptic curves

This paper improves implementation techniques of Elliptic Curve Cryptography. We introduce new formulae and algorithms for the group law on Jacobi quartic, Jacobi intersection, Edwards, and Hessian curves. The proposed formulae and algorithms can save time in suitable point representations. To support our claims, a cost comparison is made with classic scalar multiplication algorithms using previous and current operation counts. Most notably, the best speeds are obtained from Jacobi quartic curves which provide the fastest timings for most scalar multiplication strategies benefiting from the proposed 12M + 5S + 1D point doubling and 7M + 3S + 1D point addition algorithms. Furthermore, the new addition algorithm provides an efficient way to protect against side channel attacks which are based on simple power analysis (SPA). Keywords: Efficient elliptic curve arithmetic,unified addition, side channel attack.

Room for improvement : hotel giant resorts to Six Sigma to improve operations

Six Sigma provides a framework for quality improvement and business excellence. Introduced in the 1980s in manufacturing, the concept of Six Sigma has gained popularity in service organizations. After initial success in healthcare and banking, Six Sigma has gradually gained traction in other types of service industries, including hotels and lodging. Starwood Hotels and Resorts was the first hospitality giant to embrace Six Sigma. In 2001, Starwood adopted the method to develop innovative, customer-focused solutions and to transfer these solutions throughout the global organization. To analyze Starwood's use of Six Sigma, the authors collected data from articles, interviews, presentations and speeches published in magazines, newspapers and Web sites. This provided details to corroborate information, and they also made inferences from these sources. Financial metrics can explain the success of Six Sigma in any organization. There was no shortage of examples of Starwood's success resulting from Six Sigma project metrics uncovered during the research.

A general-purpose simulator for train operations

Computer simulation has been widely accepted as an essential tool for the analysis of many engineering systems. It is nowadays perceived to be the most readily available and feasible means of evaluating operations in real railway systems. Based on practical experience and theoretical models developed in various applications, this paper describes the design of a general-purpose simulation system for train operations. Its prime objective is to provide a single comprehensive computer-aided engineering tool for most studies on railway operations so that various aspects of the railway systems with different operation characteristics can be investigated and analysed in depth. This system consists of three levels of simulation. The first is a single-train simulator calculating the running time of a train between specific points under different track geometry and traction conditions. The second is a dual-train simulator which is to find the minimum headway between two trains under different movement constraints, such as signalling systems. The third is a whole-system multi-train simulator which carries out process simulation of the real operation of a railway system according to a practical or planned train schedule or headway; and produces an overall evaluation of system performance.

Constructing leadership in child care : epistemological beliefs and transformational leadership

Early childhood education and care (ECEC) in Australia are currently a focus of social and economic policy. However, early childhood leadership in Australia is yet to develop a clear identity that will enable the field to develop to its full potential. In this paper we investigate a unique theoretical framework for constructing leadership identity, based on transformational leadership and epistemological beliefs. Using semistructured interviews, 15 childcare directors from a large metropolitan area in Australia were asked to describe their beliefs about knowing in the context of their leadership practices. The findings showed that leaders (n = 5) who espoused predominantly evaluativist beliefs about knowing were more likely to describe transformational leadership behaviours in the context of childcare leadership. A number of leaders held mixed beliefs (n = 9) about knowing and described their leadership practice in ways that reflected both transactional and transformational leadership styles. Finally, one leader described predominantly objectivist epistemological beliefs and transactional beliefs about leadership. These preliminary findings show that there seems to be a relationship between core epistemological beliefs and beliefs about leadership practices and offers a new way to characterise leadership in ECEC in Australia.
