Story Points y su importancia en la estimación de proyectos bajo el enfoque agil

RESUMENUn proyecto que es abordado bajo el enfoque de desarrollo ágil de ser capaz de adaptarse a los cambios, especialmente a los requerimientos del cliente, el objetivo a la hora de encarar este tipo de proyectos es minimizar el tiempo y el costo de su realización, pero manteniendo la calidad del software y los procesos. Es por esto que el saber estimar y planificar para proyectos de desarrollo ágil es una labor trascendental y fundamental, porque no se debe perder el objetivo de este enfoque: la agilidad, centrándose en el uso de métricas que se ajusten y no se conviertan en el talón de Aquiles del equipo. En este artículo, presento algunos principios y prácticas introductorias para aprender a estimar un proyecto ágil bajo la métrica de los Story Points.ABSTRACTA project that is boarded under the approach of agile development of being able to adapt to the changes, especially to the requirements of the client, the objective at the time of facing this type of projects is to diminish the time and the cost of its accomplishment, but maintaining the quality of software and the processes. It is by that the knowledge to consider and to plan for projects of agile development is a transcendental and fundamental work, because the objective of this approach is not due to lose: the agility, concentrating in the use of metric that adjusts and does not become the heel of Aquilles of the equipment. In this article, I present/display some principles and introductory practices to learn to consider an agile project under the metric one of the Story Points

La computación evolutiva y sus paradigmas

RESUMENBasado en los principios de selección natural descritos por Charles Darwin en su libro” El Origen de las Especies”, tiene su origen lo que se conoce como Computación evolutiva. El tomar como referente la naturaleza y cada uno de los procesos inmersos en ella, ha sido la fuente para resolver problemas sobre todo en el ámbito de la computación o en complejos procesos de optimización o cálculo. La Computación evolutiva se puede considerar como una agrupación de técnicas que responden a diferentes problemáticas, estas técnicas son: La Programación Evolutiva, las Estrategias Evolutivas y los Algoritmos Genéticos (AG), y en los años 90 la Programación Genética. La Computación Evolutiva no se ve supeditada a la resolución del problema en sí, por el contrario, ésta incluye el proceso de aprendizaje, por tal razón, está relacionado con la Inteligencia Artificial. En el presente artículo se presenta una recopilación del estado actual en el que se ha enfocado la computación evolutiva, desde sus tres principales ejes.ABSTRACTBased on the principles of natural selection described by Charles Darwin in his book "The Origin of Species" has its origin so that known as evolutionary computing. Taking as reference the nature and each of the processes involved in it, has been the source for solve problems especially in the field of computer or complex process optimization or calculus. Evolutionary Computation can be considered as a collection of techniques that address different problems, these techniques are: Evolutionary Programming, Evolutionary Strategies and Genetic Algorithms (GA), and the Genetic Programming 90 years. Evolutionary Computation is not subject to resolution of the problem itself, however, it includes the learning process, therefore it is related to Artificial Intelligence

International Nosocomial Infection Control Consortiu (INICC) report, data summary of 43 countries for 2007-2012. Device-associated module

We report the results of an International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2007-December 2012 in 503 intensive care units (ICUs) in Latin America, Asia, Africa, and Europe. During the 6-year study using the Centers for Disease Control and Prevention's (CDC) U.S. National Healthcare Safety Network (NHSN) definitions for device-associated health care–associated infection (DA-HAI), we collected prospective data from 605,310 patients hospitalized in the INICC's ICUs for an aggregate of 3,338,396 days. Although device utilization in the INICC's ICUs was similar to that reported from ICUs in the U.S. in the CDC's NHSN, rates of device-associated nosocomial infection were higher in the ICUs of the INICC hospitals: the pooled rate of central line–associated bloodstream infection in the INICC's ICUs, 4.9 per 1,000 central line days, is nearly 5-fold higher than the 0.9 per 1,000 central line days reported from comparable U.S. ICUs. The overall rate of ventilator-associated pneumonia was also higher (16.8 vs 1.1 per 1,000 ventilator days) as was the rate of catheter-associated urinary tract infection (5.5 vs 1.3 per 1,000 catheter days). Frequencies of resistance of Pseudomonas isolates to amikacin (42.8% vs 10%) and imipenem (42.4% vs 26.1%) and Klebsiella pneumoniae isolates to ceftazidime (71.2% vs 28.8%) and imipenem (19.6% vs 12.8%) were also higher in the INICC's ICUs compared with the ICUs of the CDC's NHSN
