Influência da revisão de atividades executadas para melhoria da acurácia na estimativa de software utilizando planning poker

Abstract – Background – The software effort estimation research area aims to improve the accuracy of this estimation in software projects and activities. Aims – This study describes the development and usage of a web application tocollect data generated from the Planning Poker estimation process and the analysis of the collected data to investigate the impact of revising previous estimates when conducting similar estimates in a Planning Poker context. Method – Software activities were estimated by Universidade Tecnológica Federal do Paraná (UTFPR) computer students, using Planning Poker, with and without revising previous similar activities, storing data regarding the decision-making process. And the collected data was used to investigate the impact that revising similar executed activities have in the software effort estimates' accuracy.Obtained Results – The UTFPR computer students were divided into 14 groups. Eight of them showed accuracy increase in more than half of their estimates. Three of them had almost the same accuracy in more than half of their estimates. And only three of them had loss of accuracy in more than half of their estimates. Conclusion – Reviewing the similar executed software activities, when using Planning Poker, led to more accurate software estimates in most cases, and, because of that, can improve the software development process.

Representações de ciência e tecnologia em Gustavo Barroso (1909-1935): nacionalismo autoritário, eugenia e antissemitismo

This study focuses on the representations of science and technology in the thinking of the Brazilian intellectual Gustavo Barroso in the period between 1909 and 1935. As one of the main leaders of the Brazilian Integralism, we will discuss,especially, his eugenic vision, prior to his participation in integralism and the influence of this science in building his authoritarian and anti-Semitic thinking. We seek to realize Gustavo Barroso dialogue, in a context of profound social and political changes, with the search for a nationalism "truly Brazilian." The methodology used was of a documentary and literature research , highlighting the analysis of Gustavo Barroso books, which were used as primary sources: Intelligencia das Coisas(1923), Aquém da Atlântida (1931), Brasil Colônia de Banqueiros (1934), O Integralismo de Norte a Sul (1934), O Quarto Império (1935) e A Palavra e o Pensamento Integralista (1935), and, also, some of his articles surveyed in the National History Museum collection. The survey results show that in this period Gustavo Barroso went on to develop in his writings an eugenic and authoritarian political vision, later, in his integralist phase, linked strongly to an anti-Semitic view.
