I present the result of a two-year research project developed at the “Instituto de Estudos de Linguagem” (IEL/Unicamp, Brazil) and also of action research I have been organizing since 2006 when I started to work as a professor at the “Universidade Federal de Sao Carlos”, in Brazil. Relying on recent developments in New Literacy Studies, I explore the concept of the continuum illiterate-literate and argue that it implies elements of transformation, as well as conservation. I also argue that three intersecting continua must be considered together: the continua oral-written, rural-urban and restricted-full literacy, always taking into consideration ethnicity as a variable (Cohen, 1974). Drawing on ethnographic fieldwork in Brazil, I show how elements of restricted literacy (Goody, 1968) are presented on the threshold of the twenty first century; how they entertain relation with the rural to urban migration and with a marked contrast between different ethnicities; and in what sense this fact may be visible in the everyday use of language and in the style inherent in it.
In this paper we suggest a simple mathematical procedure to derive the classical probability density of quantum systems via Bohr’s correspondence principle. Using Fourier expansions for the classical and quantum distributions, we assume that the Fourier coefficients coincide for the case of large quantum number. We illustrate the procedure by analyzing the classical limit for the quantum harmonic oscillator and the particle in a box, although the method is quite general. We find, in an analytical fashion, the classical distribution arising from the quantum one as the zeroth order term in an expansion in powers of Planck’s constant. We interpret the correction terms as residual quantum effects at the microscopic-macroscopic boundary.
The effects of Generalized Uncertainty Principle, which has been predicted by various theories of quantum gravity replacing the Heisenberg’s uncertainty principle near the Planck scale, on the thermodynamics of ideal Quark-Gluon Plasma (QGP) consisting of two and three flavors are included. There is a clear effect on thermodynamical quantities like the pressure and the energy density which means that a different effect from quantum gravity may be used in enhancement the theoretical results for Quark-Gluon Plasma state of matter. This effect looks like the technique used in lattice QCD simulation. We determine the value of the bag parameter from fitting lattice QCD data and a physical interpretation to the negative bag pressure is introduced.
