Instances Of Reflection Research Articles

Social criticism in David by Miguel Ángel Rojas. An approach based on recognition theory

This article corroborates Theodor Adorno’s thesis, according to which art can be an interpreter of repressed suffering. Based on an interpretive analysis of the work David, by the artist Miguel Ángel Rojas, the possibilities of art as social criticism are shown, capable of showing the repressed suffering produced by forms of contempt and non-recognition of victims of the Colombian armed conflict, at the same time than the claims and desire for peace and justice of Colombian society, which turns the work of art into an instance of reflection, analysis and discussion about criteria for satisfactory forms of social life. The notions of social criticism and social art are based on the postulates of the Critical Theory of society, especially, on Axel Honneth’s theory of recognition.

Justicia Criminal en Chile, 1842-1906 ¿Debido proceso o contención social?

During the second half of the 19th century the leadership adopted the illustrated ethos of "due process", applying pertinent legislation and central supervising politics. Nevertheless, it was rubbing ideal this one with a contextual need of social control. The hypothesis of investigation is that the advance of the pro-guarantees paradigm was molded by the urgency of the modernizing leadership to control deviations. The experience it has to serve as instance of reflection on the development of the current procedural penal reform-pro-guarantees in beginning - and the functionality that it has supported with practices of social signing and disciplining.

No fluxo da resistência: a literatura, (ainda) universo da reinvenção da diferença

In his book, The Colonizer and the Colonized (Portrait du colonise, precede du portrait du colonisateur, 1957), the Tunisian author Albert Memmi states that “the essential dilacerations of the colonized is particularly expressed and symbolized in the colonial bilinguism” (1989, p.96). This mustn’t be taken by linguistic dualism, once the language is now thought in its broader meaning, as a vehicle of culture. Memmi says that the domain of both languages by the writer who writes in a Colonized situation (in that case, African): the European language of the Colonizer and the African language throughout he interpret the world (even though it´s not his mother language) – allows the writer to participate in both “psychical and cultural kingdoms”, that is, the ideological and multivision interaction between the presented cultural universes, African and European, what builds the African literatures written in European languages. This article is offered as a reflection over this process of elaboration of “another language” that emerges of this reinvention process and transliguistic metamorphosis of (the same) Portuguese linguistic system, through which the cultural representation game is actualized to translate different nations, through different literary articulation, taking as an instance of reflection, the work of three different African writers: Luandino Vieira, Uanhenga Xitu (Angola) and Mia Couto (Mozambique).

Model of thermal wave-front distortion in interferometric gravitational-wave detectors I Thermal focusing

We develop a steady-state analytical and numerical model of the optical response of power-recycled Fabry-Perot Michelson laser gravitational-wave detectors to thermal focusing in optical substrates. We assume that the thermal distortions are small enough that we can represent the unperturbed intracavity field anywhere in the detector as a linear combination of basis functions related to the eigenmodes of one of the Fabry-Perot arm cavities, and we take great care to preserve numerically the nearly ideal longitudinal phase resonance conditions that would otherwise be provided by an external servo-locking control system. We have included the effects of nonlinear thermal focusing due to power absorption in both the substrates and coatings of the mirrors and beamsplitter, the effects of a finite mismatch between the curvatures of the laser wavefront and the mirror surface, and the diffraction by the mirror aperture at each instance of reflection and transmission. We demonstrate a detailed numerical example of this model using the MATLAB program Melody for the initial LIGO detector in the Hermite-Gauss basis, and compare the resulting computations of intracavity fields in two special cases with those of a fast Fourier transform field propagation model. Additional systematic perturbations (e.g., mirror tilt, thermoelastic surface deformations, and other optical imperfections) can be included easily by incorporating the appropriate operators into the transfer matrices describing reflection and transmission for the mirrors and beamsplitter.
