Canções no ensino de sociologia: reflexões e aplicação

As Sociology becomes a mandatory subject in the curricular componentof Brazilian high schools, we find anopportune moment to proposals and changes in the subject and in teaching, in a general aspect. It s noticed the great importance of the role that the create imagination plays in individual s formation (BACHELARD), and it s also seen that Brazilian education system has marginalized imagination to the detriment of a unifocused scientism that sterilizes creativity, playfulness and poetry in its educational process. Nevertheless, a way of thinking redefinitions to the educational horizons of Sociology as a subject and education is upheld. An educational practice that reconnects the prosaic and the poetic, using images/songs as paths/strategies of the teaching-learning process. As for that, the school structure was used where the tutor work was done to undertake experiences that made the use of songs as strategy to facilitate/stimulate the learning of the subject Sociology in high school. From thoughts and results of this experience, plus the bibliographic studies, analysis were made. The goal of this essay is to make use and stimulate the creation of poetic images from the teaching point of view, specially the Sociology subject in high school, rethinking and searching more efficient and playful ways of approaching and building educational methods from images; stimulating the development of the Thinking Reform and the Anthropoetics of the human gender (MORIN); acknowledging that imagination is an indispensable part of our integral formation

Estimação em modelos de tempo de falha acelerado para dados de sobrevivência correlacionados

We presented in this work two methods of estimation for accelerated failure time models with random e_ects to process grouped survival data. The _rst method, which is implemented in software SAS, by NLMIXED procedure, uses an adapted Gauss-Hermite quadrature to determine marginalized likelihood. The second method, implemented in the free software R, is based on the method of penalized likelihood to estimate the parameters of the model. In the _rst case we describe the main theoretical aspects and, in the second, we briey presented the approach adopted with a simulation study to investigate the performance of the method. We realized implement the models using actual data on the time of operation of oil wells from the Potiguar Basin (RN / CE).

Testes cosmológicos aplicados a modelos de energia escura

A significant observational effort has been directed to investigate the nature of the so-called dark energy. In this dissertation we derive constraints on dark energy models using three different observable: measurements of the Hubble rate H(z) (compiled by Meng et al. in 2015.); distance modulus of 580 Supernovae Type Ia (Union catalog Compilation 2.1, 2011); and the observations of baryon acoustic oscilations (BAO) and the cosmic microwave background (CMB) by using the so-called CMB/BAO of six peaks of BAO (a peak determined through the Survey 6dFGS data, two through the SDSS and three through WiggleZ). The statistical analysis used was the method of the χ2 minimum (marginalized or minimized over h whenever possible) to link the cosmological parameter: m, ω and δω0. These tests were applied in two parameterization of the parameter ω of the equation of state of dark energy, p = ωρ (here, p is the pressure and ρ is the component of energy density). In one, ω is considered constant and less than -1/3, known as XCDM model; in the other the parameter of state equantion varies with the redshift, where we the call model GS. This last model is based on arguments that arise from the theory of cosmological inflation. For comparison it was also made the analysis of model CDM. Comparison of cosmological models with different observations lead to different optimal settings. Thus, to classify the observational viability of different theoretical models we use two criteria information, the Bayesian information criterion (BIC) and the Akaike information criteria (AIC). The Fisher matrix tool was incorporated into our testing to provide us with the uncertainty of the parameters of each theoretical model. We found that the complementarity of tests is necessary inorder we do not have degenerate parametric spaces. Making the minimization process we found (68%), for the Model XCDM the best fit parameters are m = 0.28 ± 0, 012 and ωX = −1.01 ± 0, 052. While for Model GS the best settings are m = 0.28 ± 0, 011 and δω0 = 0.00 ± 0, 059. Performing a marginalization we found (68%), for the Model XCDM the best fit parameters are m = 0.28 ± 0, 012 and ωX = −1.01 ± 0, 052. While for Model GS the best settings are M = 0.28 ± 0, 011 and δω0 = 0.00 ± 0, 059.
