Concilier les données qualitatives et quantitatives: un défi pour les recherches en acquisition du langage

What is the role of qualitative data? How should mixed approaches be considered? Is it necessary to complement the quantitative approach by the qualitative approach (Maziére et al., 2010) or the opposite? How can these two approaches be combined in a Language Acquisition research? What are the possibilities of generalization that these approaches provide? Besides those necessary theoretical discussions, our starting point is a qualitative research on the acquisition of the plural morpheme in Brazilian Portuguese (BP) in children between 1 year 11 months old and 2 years 7 months old (Hilário, 2012), whose linguistic production is intrinsically connected to their dialogic aspect (Bakhtin & Vološinov, 1973) and to the interaction among interlocutors (Bruner, 2004; Vygotsky, 1986). In this research through the usage of a computational tool (CLAN) it is expected to have more visibility of the quantitative results even if they are in a qualitative approach. Although, it should be taken into account the fact that each approach can achieve valid and relevant results (Valsiner 2000), i.e., with any given method it is possible to reach a kind of generalization (statistical or analytical).

A educação do leitor em Machado de Assis: da crítica literária às Memórias Póstumas de Brás Cubas

Les textes de critique littéraire de Machado de Assis montrent la préoccupation de l'auteur avec le lecteur; mais c'est dans l'oeuvre Memorias Postumas de Brás Cubas que le lecteur aura une participation décisive dans la structure du roman.

Espaços e fronteiras da liberdade de expressão em blogs na internet

Dans cet article, j´étudie la notion courante de liberté d´expression, fréquemment associée aux pratiques de l´écriture sur internet, par exemple, celle des blogues. Du point de vue de l´Analyse du Discours, je m´occupe des questions de l´ordre linguistique et discursive qui peuvent favoriser l´émergence de certains énoncés dans le réseau à cause de la multiplicité des relations qui permettent que le(s) dire(s) apparaisse(nt) dans la société contemporaine. En particulier, je cherche à caractériser les conditions de production du language en réseau pour constituer l´espace, compris selon une problématique sociale (SANTOS, 1996, 2008), par sa relation avec l´histoire, comprise en discontinuité (FOUCAULT, 1997).

Cacaso não é bem o caso do acaso

À partir de la lecture de quelques poèmes de Lero-lero, l'ensemble de l'oeuvre poétique de Cacaso, cet article interroge sur la vision que la poésie marginale n'a pas de valeur du point de vue littéraire, ayant été construite seulement par l'expressivité spontanée des événements quotidiens, se passant de l'élaboration poétique. Au contraire, on constate que les poèmes de Cacaso visent la construction d'un simulacre de spontanéité soutenu pas par une négligence formelle, mais par une dépuration du langage qui possibilite mettre sur la corde raide les valeurs dites littéraires.

Responda, cadáver: o discurso da crise na poesia moderna

Sociedade civil, entre o político-estatal e o universo gerencial

Cet article est fondé sur le concept de société civile développé par le marxiste Antonio Gramsci et propose un dialogue critique avec les autres idées de la société civile qui, de nos jours, cherchent à s'affirmer dans le panorama politique et culturel. Nous nous fondons sur le fait d'être passé, au cours des dernières décennies, d'une idée de société civile prioritairement politique-publique, scène de luttes démocratiques et de nouvelles hégémonies, vers une image qui transforme la société civile soit en ressource de gestion ­ un arrangement de la société destiné à rendre possible différents genres spécifiques de politiques publiques ­ soit en un facteur de reconstruction étique et dialogique de la vie sociale. L'incorporation de l'idée de participation au langage de planification a déplacé la société civile de son champs principal (celui de l'organisation de nouvelles hégémonies) vers un espace de coopération et de gestion de la crise. Par ailleurs, l'expansion de l'activisme social, dans un cadre de crise politique de l'État et de la démocratie représentative a poussé vers la recherche d'une autre «place» à partir de laquelle il serait possible d'établir et de répandre de nouvelles postulations éthiques et de nouvelles procédures collectives. D'une phase où le marxisme était prépondérant et laissait sa marque, nous sommes entrés dans une phase dans laquelle la perspective libérale, affirmée de façon orthodoxe ou nuancée, prévaut et opère comme principale référence.

Binding energies of excitons trapped by ionized donors in semiconductors

Using the hyperspherical adiabatic approach in a coupled-channel calculation, we present precise binding energies of excitons trapped by impurity donors in semiconductors within the effective-mass approximation. Energies for such three-body systems are presented as a function of the relative electron-hole mass sigma in the range 1 less than or equal to1/sigma less than or equal to6, where the Born-Oppenheimer approach is not efficiently applicable. The hyperspherical approach leads to precise energies using the intuitive picture of potential curves and nonadiabatic couplings in an ab initio procedure. We also present an estimation for a critical value of sigma (sigma (crit)) for which no bound state can be found. Comparisons are given with results of prior work by other authors.

Spin reversal and magnetization jumps in ErMexMn1-xO3 perovskites (Me = Ni, Co)

The erbium-based manganite ErMnO3 has been partially substituted at the manganese site by the transition-metal elements Ni and Co. The perovskite orthorhombic structure is found from x(Ni) = 0.2-0.5 in the nickel-based solid solution ErNixMn1-xO3, while it can be extended up to x(Co) = 0.7 in the case of cobalt, provided that the synthesis is performed under oxygenation conditions to favor the presence of Co3+. Presence of different magnetic entities (i.e., Er3+, Ni2+, Co2+, Co3+, Mn3+, and Mn4+) leads to quite unusual magnetic properties, characterized by the coexistence of antiferromagnetic and ferromagnetic interactions. In ErNixMn1-xO3, a critical concentration x(crit)(Ni) = 1/3 separates two regimes: spin-canted AF interactions predominate at x < x(crit), while the ferromagnetic behavior is enhanced for x > x(crit). Spin reversal phenomena are present both in the nickel- and cobalt-based compounds. A phenomenological model based on two interacting sublattices, coupled by an antiferromagnetic exchange interaction, explains the inversion of the overall magnetic moment at low temperatures. In this model, the ferromagnetic transition-metal lattice, which orders at T-c, creates a strong local field at the erbium site, polarizing the Er moments in a direction opposite to the applied field. At low temperatures, when the contribution of the paramagnetic erbium sublattice, which varies as T-1, gets larger than the ferromagnetic contribution, the total magnetic moment changes its sign, leading to an overall ferrimagnetic state. The half-substituted compound ErCo0.50Mn0.50O3 was studied in detail, since the magnetization loops present two well-identified anomalies: an intersection of the magnetization branches at low fields, and magnetization jumps at high fields. The influence of the oxidizing conditions was studied in other compositions close to the 50/50 = Mn/Co substitution rate. These anomalies are clearly connected to the spin inversion phenomena and to the simultaneous presence of Co2+ and Co3+ magnetic moments. Dynamical aspects should be considered to well identify the high-field anomaly, since it depends on the magnetic field sweep rate. (C) 2006 Elsevier B.V. All rights reserved.

Inhibiting effect of citric acid on the pitting corrosion of tin

Potentiostatic and potentiodynamic studies were carried out to establish the inhibiting effects of citric acid on the pitting corrosion of tin. The critical potential (E-crit), which leads to pitting or general corrosion, was determined in sodium perchlorate solution in the pH range 1.0 to 4.0. Pit nucleation and growth, at pH 4.0, can be described by instantaneous nucleation followed by progressive nucleation. The results show that the minimum acid concentration needed to inhibit pitting of tin is 10(-2) M. Pitting occurrence by direct interaction between metal and perchlorate anions was observed.
