Crianças, museus e formação de público em São Paulo

A partir de sua experiência pessoal, de frequentadora de museus desde a infância, e profissional, atuando em uma instituição cultural que abriga um museu, a arte-educadora Paula Hilst Selli discute neste livro a relação entre os museus e seu público. Sua suposição inicial é que os museus não fazem parte das opções de lazer para a maioria da população porque a formação de público dessas instituições está ligada diretamente à infância e à experiência construída nessa fase. A partir dessa ideia, sugere questões: Será que as crianças de hoje frequentam museus? Como? Com quem? O que será que elas pensam ou imaginam acerca desses espaços? Será que nesses ambientes são estimuladas à construção do conhecimento? As crianças são protagonistas ou figurantes das ações educativas? Assim, por meio de uma pesquisa realizada com crianças, a autora busca saber o que elas pensam a respeito dos museus e como se relacionam com eles, para, então, refletir sobre o acesso e a formação de público desse tipo de equipamento cultural na cidade de São Paulo. Além de investigar o papel que o museu assume no imaginário infantil e quem são os principais responsáveis por intermediar o contato entre as crianças e essas instituições, a arte-educadora analisa documentos oficiais e estudos históricos com o objetivo de discutir as responsabilidades no acesso a bens culturais

Finite-time synchronization of tunnel-diode-based chaotic oscillators

This paper addresses the problem of finite-time synchronization of tunnel diode based chaotic oscillators. After a brief investigation of its chaotic dynamics, we propose an active adaptive feedback coupling which accomplishes the synchronization of tunnel-diode-based chaotic systems with and without the presence of delay(s), basing ourselves on Lyapunov and on Krasovskii-Lyapunov stability theories. This feedback coupling could be applied to many other chaotic systems. A finite horizon can be arbitrarily established by ensuring that chaos synchronization is achieved at a pre-established time. An advantage of the proposed feedback coupling is that it is simple and easy to implement. Both mathematical investigations and numerical simulations followed by PSPICE experiment are presented to show the feasibility of the proposed method.

Desafios contemporâneos da educação

Se historicamente a educação escolar no Brasil foi marcada por um profundo corte elitista, o processo de democratização do ensino apresentou incontestáveis avanços desde a Constituição de 1988. A caminhada pela universalização, no entanto, não se deu à margem de suas heranças históricas, bem como novas fronteiras surgiram para o desafio da educação emancipatória. Esta obra reúne 17 ensaios que debatem os dilemas existentes no cotidiano da sala de aula. Divididos em três partes - " Educação, culturas realidade social", "Políticas educacionais" e "A escola" -, os textos coligidos abordam temas variados relacionados à prática escolar, como cidadania, políticas afirmativas e gestão administrativa, e compõem um cenário contemporâneo dos principais desafios colocados para a educação de nosso tempo.

O acesso à universidade pública no Brasil e a questão social: uma análise dos dados do relatório do vestibular da Universidade Estadual Paulista Julio Mesquita Filho UNESP

This work has as a central concern in analyze the causes of the still limited access of young Brazilians to public higher education in socioeconomic and cultural.In Brazil, onçy 14,4% of the young between 18 and 24 years old attend this educational level.If we consider that the public university offer just 1/4 of the vacancies, can be affirmed that this institutions are not able to attend neither 4% of the young between 18 and 24.Brazil shows,in this level of education,a lower access that most of its neighbors: Argentina(40%), Venezuela(26%), Chile(20%),Bolivia(20%).In this work were analyzed the data reports of entrance exam of Universidade Estadual Paulista (Unesp) entre 2004 e 2009,prepared by Fundaçao para o Vestibular da Universidade Estadual Paulista(Vunesp). In this analysis,can be noted the influence of some aspects socioeconomic and cultural related to possibilities os the young acces to public univercity. Stand out among these: family income,the possibility to dadicate only to studies and attend preparatory courses,as well as the parents level of education.

Um mesmo professor da 1ª à 4ª série do ensino fundamental: uma chance para o sucesso

This article discuses the ramifications of the restructuring of educational institutions of the state basic education in the state of São Paulo in 1996. The changes promoted by the Education Department included the distinction between physical space including students from lower grades of elementary school students and the second cycle of this level of education. More that issues relating to changes in itself, is important here to check the influence that managers exercise, especially school principals in the perception of the community (parents, students etc.) relative to the changes implemented in the field of education. v

Desenvolvimento de uma ontologia para apoiar a adoção do modelo MPS para software

O principal objetivo deste artigo é contribuir com a adoção do modelo de referência MPS para Software (MPS-SW). Para isso, é proposta uma ontologia dos níveis G e F do modelo, visando apoiar a compreensão e implementação desses níveis. O modelo MPS-SW é adequado a micro, pequenas e médias empresas (mPME), assim como a empresas de grande porte. A proposta pretende mitigar os investimentos técnicos e financeiros na implantação e treinamento do modelo, principalmente nas mPME. Neste contexto, este artigo apresenta a metodologia utilizada para o desenvolvimento da ontologia, com a inclusão de conhecimentos de especialistas no modelo, conceitos do PMBOK (Project Management Body of Knowledge) e indicadores do BSC (Balanced Scorecard). A partir de testes centrados no usuário, foi gerada uma versão beta da ontologia, que está disponível em repositórios livres e gratuitos.

Aprendizagem de máquina para análise de indicadores na engenharia de software

Indicadores de desempenho são importantes recursos para a gestão da qualidade no desenvolvimento de software. O volume de dados produzido por esses indicadores tende a aumentar significativamente com o tempo de monitoração, dificultando análises e tomadas de decisão. As bases históricas tornam-se complexas, considerando a quantidade de dados monitorados e a diversidade de indicadores (diferentes tipos, granularidade e frequência). Este trabalho propõe o uso de técnicas de aprendizagem de máquina para análise dessas bases, utilizando redes neurais artificiais combinadas com técnicas de visualização de informação. É utilizado um modelo de indicadores, com base nos processos do modelo de referência MPS para Software (MPS-SW), agrupados segundo as perspectivas estratégicas do Balanced Scorecard (BSC).

THE INFLUENCE OF THE 1992-1993 EL NINO ON THE REPRODUCTIVE BIOLOGY OF Scomber japonicus peruanus (JORDAN & HUBB, 1925)

The influence of the 1992-1993 El Nino events on the reproductive behavior of the Scomber japonicus peruanus (Chub mackerel) was studied from samples collected monthly, along the Peruvian coast (3 degrees 23`S-14 degrees 00`S), from January 1990 to December 1993. The monthly variation of the gonadosomatic index and the frequency of the periods of gonad maturation evidenced that the spawning of the species occurred all year long, being more intense in summer. The values of the gonadosomatic index were higher during the occurrence of the 1992-1993 El Nino, while the body weight and gonad weight decreased. Regarding the condition factor, its values decreased in females over 35 cm in fork length.

Growth parameters and mortality rate of the Scomber japonicus peruanus (Jordan & Hubb, 1925) along the Peruvian coast, South Pacific

The growth parameters and the mortality rates of the Scomber japonicus peruanus (Chub mackerel) were studied based on monthly data of frequency of fork length classes obtained from commercial landings off the Peruvian coast from 1996 to 1998. The asymptotic body length and growth rate values obtained by the ELEFAN I (Electronic Length Frequency Analysis) ranged from 40.20 cm to 42.20 cm and from 0.38 to 0.39, respectively. The oscillation amplitude was 0.60; the Winter point values varied from 0.50 to 0.60 and the performance index from 2.79 to 2.84. The total mortality rate of the Chub mackerel obtained by the linearized catch curve oscillated between 1.68 and 3.35. The rate of fishing mortality varied from 1.16 to 2.78 and the exploitation rate from 0.68 to 0.84. The annual rate of natural mortality estimated by the Pauly`s method ranged from 0.52 to 0.53. The results obtained allow us to conclude that the longevity of the Chub mackerel was slightly over seven years.

Serologic and molecular diagnostic and bioassay in mice for detection of Toxoplasma gondii in free ranges chickens from Pantanal of Mato Grosso do Sul

Holsback L., Pena H.F.J., Ragozo A., Lopes E. G., Gennari S. M. & Soares R. M. 2012. Serologic and molecular diagnostic and bioassay in mice for detection of Toxoplasma gondii in free range chickens from Pantanal of Mato Grosso do Sul. Pesquisa Veterinaria Brasileira 32(8): 721-726. Setor de Veterinaria e Producao Animal, Universidade Estadual do Norte do Parana, Campus Luiz Meneghel, Rodovia BR 369 Km 54, Bandeirantes, PR 86360-000, Brazil. E-mail: lhsfertonani@uenp.edu.br The aim of this study was to investigate the occurrence of Toxoplasma gondii and compare the results obtained in the Modified Agglutination Test (MAT), Polimerase Chain Reaction (PCR) and bioassay in mice. In order to accomplish this, 40 free-range chickens from eight farms in neighboring areas to the Pantanal in Nhecolandia, Mato Grosso do Sul, were euthanized and blood samples, brain and heart were collected. The occurrence of anti-T. gondii antibodies found in chickens was 67.5% (27 samples), considering as a cutoff point the dilution 1:5. Among the samples analyzed, 7 (25.9%) were positive in the dilution 1: 5, 3 (11.1%) in 1: 10, 2 (7.4%) in 1: 20, 3 (11.1%) in 1: 320, 1 (3.7%) in 1: 640, 3 (11.1%) in 1: 1280, 2 (7.4%) in 1: 2560, 4 (14.8%) in 1: 5120 and 2 (7.4%) in 1: 10.240. From the mixture of tissue samples (brain and heart) from the chickens analyzed, 16 (40%) presented electrophoretic bands compatible with T. gondii by PCR (gene B1). In the comparison of techniques, 59.26% positivity in PCR was revealed among animals that were seropositive in MAT (cutoff 1: 5). From 141 inoculated mice, six (4.44%) died of acute toxoplasmosis between 15 and 23 days after inoculation. Surviving mice were sacrificed at 74 days after inoculation, and a total of 28 cysts were found in the brains of 10 distinct groups. From the seropositive hens, 27 bioassays were performed and 11 (40.7%) isolates were obtained. A greater number of isolations happened in mice that were inoculated with tissues from chickens that had high titers for anti-T. gondii antibodies. Chronic infection in mice was observed in nine groups (33.3%) from five different properties. Among the surviving mice, 25.6% were positive for T. gondii in MAT (1: 25). From mice positive in PCR, 87.5% were also positive in MAT. Among the PCR-negative mice, 5.2% were positive for T. gondii in MAT. It can be concluded through this study that the occurrence of infecton by T. gondii in the rural properties studied was high, that PCR directed to gene B1 does not confirm the viability of the parasite, but it can be used as a screening method for the selection of chickens infected by T. gondii, that the animals with titer greater than 10 must be prioritized for the selection of animals for bioassay, since for them, the chances of isolating the parasite are greater and that seroconversion in experimentally infected mice is not a good indicator for isolating the agent.
