A violência da escola na voz de futuros professores: uma probabilidade da produção da cultura da violência em ambientes escolares?

The purpose of this research is to show the types of violence committed by teachers that were experienced and/or witnessed by future teachers during their schooling history. It's a quantitative and qualitative research. The collection, organization, and analysis of data proceeded from Content Analysis (BARDIN, 1977) and the construction of Bernard Charlot and Pierre Bourdieu's works and specific literature on the theme. The subjects are 12 students that attended the Pedagogy undergraduate program in 2011 at the Faculty of Science and Arts of the city of Araraquara in the state of São Paulo, Brazil. The data shows that the majority of the group of individuals claimed to have witnessed or experienced violence by teachers during their basic training. According to them, among the most recurring types of violence are those of symbolic nature. They attended, not equally, the public system and the private system. This enabled pointing out that violence, especially symbolic violence, occurred in both school systems. Therefore, this is a phenomenon that affects different fractions of social classes. Considering that the participants of this research are future teachers, it was established a relation with the notion of 'cycle of abuse', since there is a high possibility of them practicing the teaching function.

Indicadores de Avaliação de Programas de Pós-Graduação: um estudo comparativo na área da Matemática

The aim of this research is to analyze, in a comparative way, by category of grade, some indicators used by Coordination for the Improvement of Higher Education Personnel (CAPES) in evaluating the performance of Graduate Programs in Mathematics in Brazil, for the triennium 2007-2009, in order to contribute to understanding of the complex methodology involved in triennial evaluations of graduate programs. Based on the indicators present in the Comparative Worksheet of Triennial Assessment, Area Mathematics / Probability and Statistics, from 2007 to 2009, present at CAPES Portal, contingency tables were built for the 26 graduate programs in Mathematics, presenting each indicator and the program concepts. Overall, there was a trend of association of all indicators analyzed and the concept obtained, with older and larger programs with better grades in the assessment. Also, with the exception of journal articles Qualis B5, the article average per professor grows as grows the program grade.

Metodologia de determinação das curvas de probabilidade de falha S-N-P para uma liga de aluminio submetida a diferentes tratamentos termicos de solubilização e precipitação

The approach of the subject matter in this work relies on the fact that the reliability of methods for performance analysis of materials proves critical for the result. This work focused on the development and presentation of the methodology for lifting probability curves for fatigue test (SN) according to standard E739, this focus is justified by the fact that the results in fatigue test show considerable dispersion making it difficult to reading and interpretation of data, this dispersion arises because the phenomenon of rupture is strongly influenced by internal characteristics of the material, we can then have much data ranging from test to test. Thus we set out originally for a brief study of aluminum alloys in question, as well as the treatments to which they were subjected. We also studied the behavior of materials when subjected to cyclic loading, which configures process of fatigue failure, and even fatigue test method in question. This statistical analysis is based on the ASTM E739 standard, so its contents was studied in detail so that we could present in detail the methodology and raise SN curves for different aluminum alloy 7012 subjected to fatigue test. Data were collected from tests conducted in the department of materials from two samples of aluminum alloy 7012 solubilized and precipitated by different time intervals and assayed temperature fatigue-type traction-compression, these data were then analyzed and used to survey curves using the base as E739. After lifting the curve analyzed the characteristics of the test samples and their correlation with the test results. We confirmed the effectiveness of the method of statistical analysis by ASME E739, which allowed the reading of data without this method would be very difficult to have a reading and comparison of the results for the two types...

Equações de taxa aplicadas na modelagem de dispositivos fotodetectores baseados em poços quânticos

In this work, it is presented a novel method for calculating some intrinsic parameters such as capture mean time, thermic emission mean time, capture probability and noise gain on quantum well infrared photodetectors. Such devices are built by depositing layers of semiconductors of different energy gap, forming quantum wells. The present method uses rate equations to describe the occupation of discrete states of the quantum wells, that together with noise gain equations given in literature, are solved self consistently. The input data of the method is experimental measurement of dark current (current measured with no relevant incident photon) versus applied bias. In order to validate this approach, the values obtained were compared with results from literature

Confecção e caracterização de filmes finos de boro para a medida da taxa de reação 10B(N, a)7LI na terapia por captura de nêutrons pelo boro

The Boron Neutron Capture Therapy (BNCT), based on the 10B(n,α)7Li reaction, represents a promising modality for the treatment of cancers that are resistents to conventional treatments. So, it is necessary to find drugs (boron compounds) with high selectivity for each type of cancer, the neutrons source should be well characterized and the rate of 10B(n,α)7Li reaction should be measured with great accuracy as possible. This study aimed to develop a method for manufacturing thin films of boron, for measure the 10B(n,α)7Li reaction, and analyze the uniformity of the films. Five thin films of boron were manufactured with three different concentrations of boric acid, heated to transform the acid in boron, irradiated with thermic neutrons coupled to CR-39 detectors, in BNCT line at the reactor IEA-R1 IPEN/CNEN, São Paulo. After the irradiation, the detectors were chemically attacked with NaOH to reveal the tracks. The methodology presented is effective because it resulted in deposition of boron as thin film enabling the quantitative analysis of 10B(n,α)7Li reaction. The analysis of the uniformity of density of the induced tracks in CR-39 shows that, in most of the films, there is no uniformity in surface distribution of boron, but when the film is divided, we obtain some uniform sectors

Estudo da viscosidade do sangue: quantidade de amostra necessária à obtenção de medida

Os valores encontrados para a viscosidade sanguínea tendem a aparecer com diferenças significativas, de acordo com o sexo, avançar da idade e uso de substâncias. Pelo fato de o sangue ser um fluido não newtoniano, não podemos expressar sua viscosidade em termos absolutos sem que sejam levadas em conta as condições em que a mensuração é feita. Estudos anteriores destacaram a importância esta medida, considerando o efeito da idade, o uso de substâncias, bem como sua relação com Fluxo Sanguíneo Regional Cerebral, o que pode indicar correlação com declínios cognitivos. Entretanto, a prática médica carece ainda de um método simples e clinicamente prático para a verificação desta medida, além de valores de referência. Como passo inicial no sentido de padronizar os procedimentos e condições do processo de medição, avaliamos a quantidade mínima de amostra necessária para a medição da viscosidade sanguínea, utilizando este equipamento. Um total de 20 amostras de sangue foram coletadas de indivíduos saudáveis, entre 18 e 60 anos, em tubos com EDTA, e cada amostra dividida em 9 sub-amostras (de 600μl, 550μl, 500μl, 450μl, 400μl, 350μl, 300μl, 250μl e 200μl), totalizando, portanto, um total de aproximadamente 180 medições. A quantidade de 200 μl apresentou diferenças significativas com relação à primeira medida obtida, quando comparada com todas as demais quantidades (p<0,001), o que indica que com o uso desta quantidade, não é possível obter resultados confiáveis, pois existe alteração nos valores de VS obtidos relacionada à quantidade de material utilizado. Considerando a menor quantidade, bem como, que estivesse dentro da faixa de variação aceitável de 0,2 mPa.s, e a qual não apresentasse diferença significativa quando comparadas às demais (p>0,05), foi verificada a quantidade de 250 μl como a mais eficiente...

O processo de construção do conhecimento de medida numa abordagem fenomenológica

This research presents an investigation on the subject: Quantities and Measurements. The research is dedicated to this subject due to its importance in the school curriculum, and adopts the use of history of mathematics and investigative duties in a manner that will enable the production of knowledge by the student. Following a phenomenological orientation, we conducted field work in a public school in Guaratinguetá, with students from the 6 th grade. The analyze of data of the research, undertaken in accordance with the understanding of the texts FINI (1994), MACHADO (1994), BICUDO (1993, 2000, 2011), understanding how students construct knowledge measures. The data from field work were obtained from images recorded on video, the researcher's field diary and notes of the students. The descriptions of the data, transformed into text, had been detached the strechs most revealing for what it searchs to understand. The understood meaning through the analysis, indicates two categories: measure is to express values and measure is to compare quantities. When interpreting the open categories we understand that the student builds knowledge of measurement making comparisons
