Spin-glass behaviour in mixed metal oxides with a rutile-type structure

We report here on the magnetic properties of compounds of composition Fe1−xCrxSbO4 and Fe1−xGaxSbO4. The introduction of paramagnetic Cr3+ and diamagnetic Ga3+ into the rutile‐related iron antimonate lattice does not destroy the antisite atomic ordering which exists in iron antimonate of composition FeSbO4. The initial slope of the Curie temperature dependence on x is similar in both series, indicating that Fe3+‐Cr3+ interactions are very small. The magnetic susceptibility measurements recorded from the compounds of composition Fe1−xCrxSbO4, x<0.4, and Fe0.9Ga0.1SbO4 show them to behave as spin glasses at low temperatures. The inhibition of compounds of the type Fe1−xCrxSbO4, x>0.4, and Fe1−xGaxSbO4, x>0.1 to undergo a spin‐glass transition above 4.2 K is associated with a dilution effect.

Asymmetric Little spin-Glass model

We study the static properties of the Little model with asymmetric couplings. We show that the thermodynamics of this model coincides with that of the Sherrington-Kirkpatrick model, and we compute the main finite-size corrections to the difference of the free energy between these two models and to some clarifying order parameters. Our results agree with numerical simulations. Numerical results are presented for the symmetric Little model, which show that the same conclusions are also valid in this case.

Evidence of aging in spin glass mean-field models

We study numerically the out-of-equilibrium dynamics of the hypercubic cell spin glass in high dimensionalities. We obtain evidence of aging effects qualitatively similar both to experiments and to simulations of low-dimensional models. This suggests that the Sherrington-Kirkpatrick model as well as other mean-field finite connectivity lattices can be used to study these effects analytically.

Political Emotions: Civil Religion and Melodrama in Spielberg's Lincoln

This essay focuses on how Spielberg's film engages with and contributes to the myth of Lincoln as a super-natural figure, a saint more than a hero or great statesman, while anchoring his moral authority in the sentimental rhetoric of the domestic sphere. It is this use of the melodramatic mode, linking the familial space with the national through the trope of the victim-hero, which is the essay's main concern. With Tony Kushner, author of Angels in America, as scriptwriter, it is perhaps not surprising that melodrama is the operative mode in the film. One of the issues that emerge from this analysis is how the film updates melodrama for a contemporary audience in order to minimize what could be perceived as manipulative sentimental devices, observing for most of the film an aesthetic of relative sobriety and realism. In the last hour, and especially the final minutes of the film, melodramatic conventions are deployed in full force and infused with hagiographic iconography to produce a series of emotionally charged moments that create a perfect union of American Civil Religion and classical melodrama. The cornerstone of both cultural paradigms, as deployed in this film, is death: Lincoln's at the hands of an assassin, and the Civil War soldiers', poignantly depicted at key moments of the film. Finally, the essay shows how film melodrama as a genre weaves together the private and the public, the domestic with the national, the familial with the military, and links pathos to politics in a carefully choreographed narrative of sentimentalized mythopoesis.

As organizações da sociedade civil e as ONGs de educação

Esta resenha de idéias e conceitos esclarece o leitor sobre uma sucessão de termos empregados livremente nos últimos tempos: sociedade civil, ONGs, Terceiro Setor, Lei das OSC-IPs, conselhos paritários - o que vêm a ser, integrando a pauta da grande imprensa? Em abordagem simples, apresentam-se elementos da trajetória política das ONGs brasileiras dentro do cenário mais amplo da sociedade civil organizada. Discute-se o papel especial desempenhado por elas na longa luta pela socialização da educação, e seu atualíssimo dilema frente à onda de privatização de deveres constitucionais do Estado.
