O ensino de Português Língua Estrangeira no contexto virtual do Teletandem: aspectos linguístico-discursivos

The project Teletandem, linked to the Centro de Línguas e Desenvolvimento de Professores UNESP/Assis, promotes the interaction between undergraduates students in Languages and undergraduates students from foreign universities in order to promote the teaching of Portuguese for those who do not speak Portuguese and give an opportunity to Brazilian students to learn a foreign language. Therefore there is a different context that can result in new forms of statements produced in this specific area of human activity. The present paper aims to present a description of Teletandem sessions as a discursive gender according to the gender theory, showing the multiplicity of discursive genders that emerge during an interaction. We also intend to verify the levels of Critical Language Awareness among Brazilian participants according to the Critical Discourse Analysis.

Avaliação do potencial citotóxico, moluscicida e alelopático dos extratos hidroetanólicos das folhas de Stryphnodendron obovatum Benth

Stryphnodendron obovatum Benth. known as barbatimão de folha miúda, is a typical tree of the Midwest and Southeast “Cerrado” regions of Brazil. Several secondary metabolites have been identified in its barks, including tannins, described on the literature as allelochemicals. Beholding to identify a possible allelopathic activity in S. obovatum leaves, we tested hydroethanolic EtOH:H2 O (70% and 50% v/v) extracts, in different concentrations, on the initial development of cucumber (Cucumis sativus L.). Among the results, we highlight the effect of the 50% hydroethanolic extract in inhibiting the formation of the main and the secondary roots and the stimulation of the hypocotyl growth in C. sativus by the 70% hydroethanolic extract, both in all concentrations tested. The cytotoxic activity, evaluated by bioassay toxicity on Artemia salina Leach., was negative for the tested extracts (LC50> 1000 mg.mL-1). Concomitantly, the molluscicidal activity, evaluated against snails of Biomphalaria glabrata Say, presented low acute toxicity of solutions of 70% hydroethanolic extract at concentrations of 128.9 mg.mL-1 and 172.8 mg.mL-1 and values above 250 mg.mL-1 to solutions of 50% hydroalcoholic extract, being therefore considered inactive for these. The results suggest the existence of allelochemicals in the extracts tested and they have low toxicity.

On volterra integral equations on time scales

The purpose of the present paper is to study some properties of solutions of Volterra integral equations on time scales. We generalize to a time scale some known properties concerning continuity and convergence of solutions from the continuous case.

Bose-Einstein correlation measurements at CMS

Multidimensional and one-dimensional quantum-statistical (Bose-Einstein) correlations are measured in proton proton collisions at 0.9, 2.76 and 7 TeV, in proton lead collisions at 5.02 TeV/nucleon pair and peripheral lead lead collisions at 2.76 TeV/nucleon pair center-of-mass energy with the CMS detector at the LHC. The correlation functions are extracted in terms of different components of the relative momentum of the pair, in order to investigate the extension of the emission source in different directions. The results are presented for different intervals of transverse pair momentum, k(T), and charged particle multiplicity of the collision, N-tracks, as well as for their integrated values. Besides inclusive charged particles, charged pions and kaons, identified via their energy loss in the silicon tracker detector, can also be correlated. The extracted source radii increase with increasing multiplicity, and decrease with increasing k(T). The results open the possibility to study scaling and factorization properties of these radii as a function of multiplicity, k(T), colliding system size and center-of-mass energy.

Multiseries Lie groups and asymptotic modules for characterizing and solving integrable models

A multiseries integrable model (MSIM) is defined as a family of compatible flows on an infinite-dimensional Lie group of N-tuples of formal series around N given poles on the Riemann sphere. Broad classes of solutions to a MSIM are characterized through modules over rings of rational functions, called asymptotic modules. Possible ways for constructing asymptotic modules are Riemann-Hilbert and ∂̄ problems. When MSIM's are written in terms of the group coordinates, some of them can be contracted into standard integrable models involving a small number of scalar functions only. Simple contractible MSIM's corresponding to one pole, yield the Ablowitz-Kaup-Newell-Segur (AKNS) hierarchy. Two-pole contractible MSIM's are exhibited, which lead to a hierarchy of solvable systems of nonlinear differential equations consisting of (2 + 1) -dimensional evolution equations and of quite strong differential constraints. © 1989 American Institute of Physics.

"...Depois, querida, ganharemos o mundo": reflexões sobre gênero, sexualidade e políticas públicas para travestis adolescentes, meninos femininos e outras variações

This article originated in a research that was meant to map out and examine the life conditions of “travesti” (transgender) teenagers and youth living in the city of Campinas, state of São Paulo. We contacted our informants outside the environments usually identifi ed as the common spaces where members of this group spend their time and share their experiences, as a strategy that we believed could enable us to better perceive how they construct their subjectivities. As we began our ethnographic endeavors, we were surprised by the multiplicity of ways in which these young people experimented with gender and sexuality, yet which were, at the same time, accompanied by eff orts to fi t these experiments within available identity categories. Feminine boys, cross dressers and drags thus constructed their own ways of living the feminine, and in doing so, stirred our imagination regarding contemporary experiences and political struggles in the realm of sexuality.
