Novo algoritimo genético para problemas de cobertura de conjuntos

The Set Covering Problem (SCP) plays an important role in Operational Research since it can be found as part of several real-world problems. In this work we report the use of a genetic algorithm to solve SCP. The algorithm starts with a population chosen by a randomized greedy algorithm. A new crossover operator and a new adaptive mutation operator were incorporated into the algorithm to intensify the search. Our algorithm was tested for a class of non-unicost SCP obtained from OR-Library without applying reduction techniques. The algorithms found good solutions in terms of quality and computational time. The results reveal that the proposed algorithm is able to find a high quality solution and is faster than recently published approaches algorithm is able to find a high quality solution and is faster than recently published approaches using the OR-Library.

Estratégias tecnológicas em transformação: um estudo da indústria farmacêutica brasileira

The aim of this research is to analyze the extension of changes in technological strategies of a group of Brazilian pharmaceutical companies, which we believe were induced by transformations in the institutional environment during the 1990s. Major institutional changes, such as the enacting of laws that recognized drug patents rights and fostered generic drugs market, have strengthened the market insertion and competitive position of these companies, what would enable an increase in research and development efforts in Brazil. In addition to the literature on technology strategy and drug industry, this study was based on interviews with six Brazilian pharmaceutical companies, all of which were ranked among the top national companies in the industry and have been considered in previous studies particularly active in the process of changing technological strategies. This research confirmed a significant intensification of technology efforts carried out by Brazilian drug companies. Nevertheless, the R&D intensity is still far below the global pattern and innovative impacts are slight.

Programa informativo sobre deficiência mental e inclusão: mudanças nas atitudes socias de crianças sem deficiência

This article presents part of a study that analyzed the concepts, feelings and attitudes of children without disabilities about mental retardation and inclusion and evaluated the effects of an informative program that deals with the issue. The study included forty children from two first grade classrooms in a public school in Marília-SP. One classroom participated as a control group. All children underwent pre and post tests in the form of interviews on the subject and a scale of children's social attitudes towards inclusion was applied. The experimental group participated in the informative program, composed of thirteen weekly meetings, in which the limitations and possibilities of people with mental retardation, specialized care, their schooling and family and social aspects, were discussed, using various educational and recreational strategies. The data collected in the interviews were categorized and content analysis was conducted. With the scale, individual scores were obtained. Statistical calculations were performed to verify the significance of differences between groups. In this paper we discuss the data obtained with the scale which were crossed with interview data. The results of the interviews and the scale indicated several changes in children's attitudes towards inclusion, but relations between many of these data could not be statistically confirmed. These results indicate the importance of expanding the research on the relationship between the phenomena presented.

Polifonia, carnavalização e paródia na Teoria do Medalhão, de Machado de Assis: confronto com Le Père Goriot, de Balzac

In the short story “Teoria do Medalhão”, written by Machado de Assis in 1881, a zealous father decides to give good advices to his son who just turned 21 years old. Using a speech that represents the official ideology of the eighteenth century, created by the dominant hegemony, including the France of Balzac’s time, the father suggests that the son abandons his ideals, using masks and annulling his thoughts and tastes to become a true Medalhão. The dialogue that is established between both of them is surrounded by irony and humor, because the father makes an apparently wise speech, which is, actually, empty and fool, leading to think about the concepts of parody and carnavalization by Bakhtin. Besides that, when he built a story in dialogue form, Machado de Assis transfers the word to the characters, in a crossing of voices that makes us think about “embryos” of polyphony. This work aims to make a bakhtiniana reading of the machadiano short story, “Teoria do Medalhão” in opposition to the novel Le Père Goriot by Balzac.

Desdobramentos do exílio em Romance com argentinos (1990), de Luisa Valenzuela

En Novela negra con argentinos, publicada en 1990, la escritora Luisa Valenzuela se propone a discutir la sociedad moderna en un cruce apropiado entre género y personajes. Al representar la ciudad de Nueva York, bajo sus aspectos más degradantes e inhumanos con reverberaciones de la política argentina, Valenzuela da vida a un relato construido a partir del diálogo entre el discurso ficcional y histórico, de los desdoblamientos de la experiencia del exilio y la identidad contemporánea argentina.

O uso de ducha: efeito sobre o bem-estar e a qualidade da carcaça e da carne em suínos transportados para o abate

This study was carried out to evaluate the effects of a shower before and after pig transportation on welfare, meat and carcass quality. We used 384 crossbreeding animals (females and castrated males), from 16 farms in Santa Catarina State, Brazil. A 2x4 factorial arrangement of treatments was employed with two distances from farm to slaughter plant (less than 50km and more than 50km) and four showering protocols. These protocols were applied on pigs: no showering at farm or slaughter plant (Control), no showering at farm but showering at the plant (NMG_MOF); showering at the farm and no showering at the plant (MOG_NMF); showering at the farm and plant (MOG_MOF). None of the factors influenced (P>0.05) physiological variables related to stress (cortisol and lactate in blood samples), number of carcass lesions and the characteristics of meat quality.
