A trajetória de Anísio Teixeira entre 1935 e 1946: uma história contada pela sua correspondência com Monteiro Lobato e Fernando de Azevedo

O intuito do presente texto é destacar na trajetória de Anísio Teixeira ciclos que permitem observar momentos, idéias e fases de sua biografia. Para tanto, vale observar que a idéia de ciclos não se refere apenas a uma forma de delimitação biográfica da vida de Anísio, pois visa colocar em perspectiva o modo de constituição do pensamento e das posições desse educador. Desse modo, a sua correspondência com Fernando de Azevedo e Monteiro Lobato é tomada como produção que atravessa diferentes fases de sua trajetória, permitindo observar o quanto suas posturas e convicções se preservam ou são alteradas ao longo do tempo, em especial durante o período em que esteve afastado da vida publica entre 1936 e 1946.

Fernando de Azevedo: institucionalização da sociologia e modernização brasileira

O artigo desenvolve uma reflexão acerca da contribuição de Fernando Azevedo para a institucionalização da sociologia no Brasil, dando ênfase também a seu papel no processo de modernização ocorrido no país entre as décadas de 1930 e 1960. Nesse sentido, o trabalho procura articular “texto” e “contexto”, como uma opção metodológica, e aponta como hipótese principal que a trajetória institucional e as obras de Azevedo representam um caminho profícuo para se revisar criticamente algumas das explicações canônicas sobre a história das Ciências Sociais no Brasil. Em particular, são destacadas aquelas interpretações que abordaram o tema privilegiando o processo de institucionalização como viés explicativo, inclusive, dando ênfase à década de 1960 como o seu marco inicial. Como resultado do ângulo adotado foi possível chegar a uma versão distinta, ainda que preliminar, dessa história, mostrando que Fernando de Azevedo ocupou um lugar destacado tanto para a institucionalização das Ciências Sociais quanto para o processo de modernização do país.

Fernando de Azevedo: dilemas na institucionalização da sociologia no Brasil

Alessandra Santos Nascimento discute, neste livro, o papel desempenhado por Fernando de Azevedo (1894-1974) na institucionalização da Sociologia no país, refletindo também acerca de atuação do sociólogo, professor e escritor mineiro radicado em São Paulo no processo de modernização do Brasil entre as décadas de 1930 e 1960. A pesquisadora lança a hipótese de que a trajetória institucional e a obra de Fernando Azevedo - que escreveu perto de duas dezenas de livros e centenas de ensaios e artigos, principalmente para o jornal O Estado de São Paulo - demonstram que a história das Ciências Sociais no Brasil demanda uma interpretação diferente da que hoje vigora quase como um cânone: a de que sua institucionalização teria ocorrido a partir da década de 1960. Para a autora, a atuação de Azevedo mostra que tal processo começou bem mais cedo: no fim dos anos 1920 ele já despontara como significativo intérprete da cultura nacional, apaixonado humanista e importante construtor institucional do que aos poucos se tornariam as Ciências Sociais brasileiras.

Study of the phenomena of fatigue using the finite element method

About 99% of mechanical failures are consequence of the phenomena of fatigue, which consists on the progressive weakening of the resistant section of a mechanical component due to the growing of cracks caused by fluctuating loadings. A broad diversity of factors influences the fatigue life of a mechanical component, like the surface finishing, scale factors, among others, but none is as significantly as the presence of geometric severities. Stress concentrators are places where fatigue cracks have a greater probability to occur, and so on, the intuit of this work is to develop a consistent and trustfully methodology to determine the theoretical stress concentration factor of mechanical components.

Os estudos clássicos no Brasil colonial: uma breve proposta para a reintrodução de um assunto

This paper wishes to reintroduce, in a brief manner, a subject which has been neglected in the recent past: the history of Classical Studies in colonial Brazil. As an introduction to this complex issue, it aims at a historical review of the ideal of humanitas in the Academias of the eighteenth century. The presence of this ideal in the Academias is seen as a result of the classical education of the Brazilian people, a process which begins with the arrival of Jesuit missionaries in 1549 and 1553. In our discussion, we shall use the ideas of Dante Tringali (1994), Fernando de Azevedo (1958), Antônio Cândido (1977), José Aderaldo Castello (1969), among others.

Comparison of frequency and time domain electromyography parameters in women with patellofemoral pain

Despite its high incidence, patellofemoral pain etiology remains unclear. No prior study has compared surface electromyography frequency domain parameters and surface electromyography time domain variables, which have been used as a classic analysis of patellofemoral pain. Thirty one women with patellofemoral pain and twenty eight pain-free women were recruited. Each participant was asked to descend a seven step staircase and data from five successful trials were collected. During the task, the vastus medialis and vastus lateralis muscle activities were monitored by surface electromyography. The data were processed and analyzed in four variables of the frequency domain (median frequency, low, medium and high frequency bands) and three time domain variables (Automatic, Cross-correlation and Visual Onset between the vastus medialis and vastus lateralis muscles). Reliability, Receiver Operating Characteristic curves and regression models were performed. The medium frequency band was the most reliable variable and different between the groups for both muscles, also demonstrated the best values of sensitivity and sensibility, 72% and 69% for the vastus medialis and 68% and 62% for the vastus lateralis, respectively. The frequency variables predicted the pain of individuals with patellofemoral pain, 26% for the vastus medialis and 20% for the vastus lateralis, being better than the time variables, which achieved only 7%. The frequency domain parameters presented greater reliability, diagnostic accuracy and capacity to predict pain than the time domain variables during stair descent and might be a useful tool to diagnose individuals with patellofemoral pain.

Reduced knee flexion is a possible cause of increased loading rates in individuals with patellofemoral pain

Stair ascent is an activity that exacerbates symptoms of individuals with patellofemoral pain. The discomfort associated with this activity usually results in gait modification such as reduced knee flexion in an attempt to reduce pain. Although such compensatory strategy is a logical approach to decrease pain, it also reduces the normal active shock absorption increasing loading rates and may lead to deleterious and degenerative changes of the knee joint. Thus, the aims of this study were (i) to investigate whether there is reduced knee flexion in adults with PFP compared to healthy controls; and (ii) to analyze loading rates in these subjects, during stair climbing. Twenty-nine individuals with patellofemoral pain and twenty-five control individuals (18-30years) participated in this study. Each subject underwent three-dimensional kinematic and kinetic analyses during stair climbing on two separate days. Between-groups analyses of variance were performed to identify differences in peak knee flexion and loading rates. Intraclass correlation coefficient was performed to verify the reliability of the variables. On both days, the patellofemoral pain group demonstrated significantly reduced peak knee flexion and increased loading rates. In addition, the two variables obtained high to very high reliability. Reduced knee flexion during stair climbing as a strategy to avoid anterior knee pain does not seem to be healthy for lower limb mechanical distributions. Repeated loading at higher loading rates may be damaging to lower limb joints.

Q-angle static or dynamic measurements, which is the best choice for patellofemoral pain?

The elevated Q-angle seems to be one of the most suggested factors contributing to patellofemoral pain. Females with patellofemoral pain are often evaluated through static clinical tests in clinical practice. However, the adaptations seem to appear more frequently in dynamic conditions. Performing static vs. dynamic evaluations of widely used measures would add to the knowledge in this area. Therefore, the aim of this study was to determine the reliability and discriminatory capability of three Q-angle measurements: a static clinical test, peak dynamic knee valgus during stair ascent and a static measurement using a three-dimensional system. Twenty-nine females with patellofemoral pain and twenty-five pain-free females underwent clinical Q-angle measurement and static and dynamic knee valgus measurements during stair ascent, using a three-dimensional system. All measurements were obtained and comparisons between groups, reliability and discriminatory capability were calculated. Peak dynamic knee valgus was found to be greater in the patellofemoral pain group. On the other hand, no significant effects were found for static knee valgus or clinical Q-angle measurements between groups. The dynamic variable demonstrated the best discriminatory capability. Low values of reliability were found for clinical Q-angle, in contrast to the high values found for the three-dimensional system measurements. Based on our findings, avoiding or correcting dynamic knee valgus during stair ascent may be an important component of rehabilitation programs in females with patellofemoral pain who demonstrate excessive dynamic knee valgus. Q-angle static measurements were not different between groups and presented poor values of discriminatory capability.

Whistle variability in South Atlantic spinner dolphins from the Fernando de Noronha Archipelago off Brazil

A series of quali- and quantitative analyses were conducted to evaluate the variability of spinner dolphin whistles from the Fernando de Noronha Archipelago off Brazil. Nine variables were extracted from each whistle contour, and the whistle contours shapes were classified into the seven categories described in Driscoll (1995). The analysis showed mean beginning and ending frequencies values of 10.78 and 12.74 kHz, respectively. on average, whistle duration was relatively short, with mean values around 0.495 s (N=702). Comparative analyses were also conducted to investigate the relationship between the obtained results and those presented in previous studies. When comparing averages, the results of the study of Oswald et al. (2003) in the Tropical Eastern Pacific (TEP) presented less significant differences in relation to this study; only whistle duration differed significantly between both works. The results of multivariate classification tests also pointed TEP population as the closest related to the population studied here. The similarities between such disjunct populations might be attributed to a more recent isolation event (the closing of the Panama Isthmus) than the divergence that has driven North and South Atlantic populations apart.
