This article analyzes the ideas and the work of Anísio Teixeira in the 1920s and 1930s, focusing on his views about the value of measurement for educational reform in Brazil. Considering that the thinking and practices of Teixeira should be understood in the context in which it was developed, the study presents the history of the presence of psychological knowledge in education, with special attention to the entrance of the Psychometrics in the New School movement. The paper concludes that, by defending the use of measurement, Teixeira has remained true to the goal of the New School that required to diagnoses scientifically the school universe, which was necessary to respond to the growing demand for schooling and the educational disabilities of the Brazilian educational institutions.

The aim of the present study was to determine the size at sexual maturity in the freshwater crab Dilocarcinus pagei Stimpson, 1861, from a population located in Mendonça, state of São Paulo, Brazil. The crabs were sampled monthly (July 2005 to June 2007), at Barra Mansa reservoir. The specimens were captured manually or in sieves passed through the aquatic vegetation. The crabs were captured and separated by sex based on morphology of the pleon and on the number of pleopods. The following dimensions were measured: carapace width (CW); carapace length (CL); propodus length (PL); and abdomen width (AW). The morphological analysis of the gonads was used to identify and categorize individuals according to their stage of development. The morphological maturity was estimated based on the analysis of relative growth based on the allometric equation y = ax b. The gonadal maturity was based on the morphology of the gonads by the method CW50 which indicates the size at which 50% of the individuals in the population showed gonads morphologically mature to reproduction. The biometric relationships that best demonstrated the different patterns of growth for the juvenile and adult stages were CW vs. PL for males and CW vs. AW for females (p<0.001). Based on these relationships, the estimated value to morphological sexual maturity was 21.5 mm (CW) in males and 19.7 mm (CW) in females. The determination of the size at sexual maturity and the adjustment of the data based on the logistic curve (CW50) resulted in a size of 38.2 mm for males and 39.4 mm for females (CW). Based on the data obtained for sexual maturity for D. pagei, we can estimate a minimum size for capture of 40 mm (CW). This minimum size allows at least half of the population to reproduce and retains the juveniles and a portion of the adults in the population.

This search is part of a larger study conducted at the Carlos Chagas Foundation (SP-Brazil), which aims to build a scale to assess adhesion to moral values by basic education students and their teachers. This text addresses only the value of justice. The responses of 111 10-13 year old children and 121 teenagers between 14 and 17 years of age at public and private schools in the city of São Paulo (SP-Brazil) were compared. Among the various topics addressed, some issues of distributive, retributive and commutative justice were selected. In the questionnaire, the alternatives offered were built in increasing stages of decentration from a social perspective inspired by Kohlberg. The results confirmed the two hypotheses that had been raised: there was a progression in the choice of the answers concerning the stages between children and teenagers and there were differences between the three forms of justice considered, in relation to the achievement of higher levels.

El trabajo analiza la caducidad probatoria atribuida por el ordenamiento jurídico brasileño a los documentos contables. Se analizan los cambios ocurridos en la legislación brasileña durante la década de 2000, con respecto a la legitimación jurídica del uso de documentos contables electrónicos. La legislación brasileña ha sufrido cambios considerables en cuanto a los documentos contables electrónicos principalmente a partir de 2007, con el advenimiento del Sistema Público de Escritura Digital (Sped). El ordenamiento jurídico brasileño se encuentra en un período de transición. Hay diferentes interpretaciones respecto a los mecanismos previstos por este ordenamiento en cuanto a la seguridad de las informaciones contables almacenadas en el medio digital. Es necesario analizar la seguridad y los límites de la utilización de documentos contables electrónicos.

It was aimed to evaluate the chemical composition of grass silage-mombasa associated with different additives in four times of opening the silo. The experiment was conducted in UFGD. After harvesting the forage, biomass in natura crushed, was taken to the lab, homogenized and enriched on the basis of natural mass, with the following additives: 5% wheat bran, 5% of waste (broken grain and soy ice cream cone) of soybean, 5% urea in natural matter and the witness (without additive). The silos were opened after (unprocessed material), 15, 30 and 45 days, for the analysis of chemical composition. The data obtained were analyzed through the statistical programme SISVAR and averages were compared to 5% of probability, by Skott-Knot. The grass silage-mombasa without additive presented major (P<0.05) dry matter content compared to other treatments at time 0 and 30 days of silage and did not differ (P>0.05) of grass silage- mombasa associated with 5 of urea in 15 days and 45 of silage. The grass silage-mombasa with 5% urea showed the highest crude protein content at time 0 and differed from other treatments. The silage of mombasa associated with 5% urea provided greater in vitro digestibility of dry matter to 15 days of silage.

After the isolation of Helicobacter pylori from an injury at the stomach mucosa by Marshall and Wareen, work that was recognized with the Nobel Prize of Medicine or Physiology in 2005, many other works showed the relationship between the presence of H. pylori and diseases at the digestive system, such as gastritis, gastric, duodenal and peptic ulcer, and stomach cancer. The 13C-Urea Breath Test - 13C-UBT is a non-invasive diagnostic method that utilizes the breath of a patient to determine the presence of H. pylori through stable isotopes. This work aimed to find an ideal 13C-UBT Isotopic Ratio Mass Spectroscopy cut-off value (a threshold between positive and negative) to diagnose H. pylori infection at Brazilian population. Patients were selected at the UNESP-Botucatu Clinical Hospital Endoscopy Section. With these results it was possible to indicate that the best cut-off value is between 2.5 to 6 ‰ of Delta Over Baseline (DOB)

Sustainability has been moving up on the business agenda in recent decades, and many methods to assess corporate sustainability have already been created. One of the most used and reliable methods is the Sustainability Reporting Guidelines of the Global Reporting Initiative (GRI). Given the importance of sustainability for society and organizations, this study examined sustainability reports published by mining companies – Alcoa, Vale and Samarco – since 2006. The objective was to verify the indicators that contribute most to the minimization of environmental impacts and the improvement of environmental performance. The methodology consisted of collecting and analyzing data from the GRI sustainability reports. It was discovered that the sustainability reports helped the companies to identify improvement opportunities and it is essential companies provide in their reports an economic, environmental and social context of their activities. Furthermore, it was found out that the indicators related to atmospheric emissions, solid waste generation, environmental protection expenditure, and the consumption of raw materials, energy and water are the ones more attached to the production process, which means they are the main contributors for the environmental performance improvement

A captura do caranguejo-uçá (U. cordatus) constitui uma das principais fontes de alimento e renda para muitas comunidades litorâneas, sendo considerada uma das atividades extrativistas estuarinas mais antigas no Brasil. O Município de Cananéia (SP) faz parte da Área de Proteção Ambiental de Cananéia-Iguape-Peruíbe (APA/CIP), possuindo 72 km² de manguezais, que a partir de 1990 passaram a receber uma maior pressão de explotação dessa espécie pela introdução da “redinha”, um petrecho de pesca proibido por lei nas regiões sudeste-sul brasileiras (Portaria IBAMA nº 52/2003). O presente estudo visa avaliar a produção do recurso caranguejo-uçá em Cananéia (SP), identificando seu padrão explotatório recente, com vistas à sustentabilidade futura das capturas. Na avaliação foram utilizadas planilhas de dados disponibilizadas pelo Instituto de Pesca (APTA/SAA-SP), referentes aos anos de 2009 e 2010, além do acompanhamento de uma das rotinas de coleta, com realização de biometria dos caranguejos capturados. Os dados evidenciam que o uso da “redinha” apresenta falha de recolhimento de 3,6%, num total de 86,4% de produtividade, que permanecem nos manguezais, podendo (ou não) ser recolhidas por outro catador. Os dados das planilhas do IP/APTA/SAA-SP foram avaliados segundo o modelo linear generalizado (GLM), com base em seis variáveis (unidade produtiva, mês de captura, ano, fase lunar, setor produtivo e período reprodutivo da espécie), das quais o conhecimento empírico dos catadores, ano da pescaria e o setor produtivo, foram as variáveis que mais influenciaram as mudanças observadas na captura por unidade de esforço (CPUE) da espécie. Além disso, foram verificadas produtividades diferenciadas na extração de caranguejos entre os cinco setores estabelecidos, que caracterizam o Estuário de Cananéia nos dois anos analisados.
