Este ensayo procura analizar el tema de la educación a lo largo de la vida en su intersección con la escuela. En oposición a las perspectivas teóricas que defienden una posible conciliación entre vida y escuela, evidenciamos la tensión existente entre esas dos esferas, al hacer el análisis de los temas de la experiencia con el nacimiento, con la muerte y con la diferencia, y señalamos que su reflexión invita a los sujetos de la praxis educativa a una actitud ética de cuidado para con el otro, para con uno mismo y para que el otro cuide del cuidado de uno, que, de modo complementario a los saberes y prácticas escolares, posibilita una formación continuada que implica la transformación de sí mismo. Eso porque, teniendo como referencia el pensamiento de Arendt y Foucault, comprendemos que la vida transborda a los saberes y prácticas escolares, ofreciéndonos lo que pensar en la praxis educativa y haciendo que los sujetos de esa praxis aprendan a ubicarse entre la vida y la escuela, a la búsqueda de nuevos sentidos para ellos y de resistencia a lo que existe mientras se transforman a sí mismos. Así, buscamos ofrecer a los educadores algunos problemas de la vida que interfieren en la praxis educativa, que repercuten en su experiencia y que hacen pensar sobre aquello que les queda.

For the development of this graduate work of fractal fracture behavior, it is necessary to establish references for fractal analysis on fracture surfaces, evaluating, from tests of fracture tenacity on modes I, II and combined I / II, the behavior of fractures in fragile materials, on linear elastic regime. Fractures in the linear elastic regime are described by your fractal behavior by several researchers, especially Mecholsky JJ. The motivation of that present proposal stems from work done by the group and accepted for publication in the journal Materials Science and Engineering A (Horovistiz et al, 2010), where the model of Mecholsky could not be proven for fractures into grooved specimens for tests of diametric compression of titania on mode I. The general objective of this proposal is to quantify the distinguish surface regions formed by different mechanisms of fracture propagation in linear elastic regime in polymeric specimens (phenolic resin), relating tenacity, thickness of the specimens and fractal dimension. The analyzed fractures were obtained from SCB tests in mode I loading, and the acquisition of images taken using an optical reflection microscope and the surface topographies obtained by the extension focus method of reconstruction, calculating the values of fractal dimension with the use of maps of elevations. The fractal dimension was classified as monofractal dimension (Df), when the fracture is described by a single value, or texture size (Dt), which is a macroscopic analysis of the fracture, combined with the structural dimension (Ds), which is a microscopic analysis. The results showed that there is no clear relationship between tenacity, thickness and fractal values for the material investigated. On the other hand it is clear that the fractal values change with the evolution of cracks during the fracture process ... (Complete abstract click electronic access below)

Placing the management of childhood forms considered at risk, we discuss the operation of a welfare institution and its effects on the subjective process. Created to manage the virtues of the poor behavior of children, makes visible to the way technology features disciplinary policies: surveillance is evident of cameras, high walls, electric fences and in the eyes of educators, the penalty stands normalizing practices corrective aimed at standardization bodies, educational meetings are compared to the examination, as they produce dossiers of individual behavior, emphasizing characteristics that are considered dangerous anticipates the administration and production of docile individuals, useful, productive, applying identity models. Following the lines of knowledge and power relations that constitute this space, we used the genealogy in the analysis of discursive practices that cross society in its historical construction, the genealogy allows us to achieve these movements in the consolidation process of the government of life, and also, the deconstruction of hegemonic practices. In an attempt to escape the set, we propose the realization of artistic and cultural activities within a process of collective construction as a strategy of resistance and confrontation with the dominant logic, consolidating practices that favor the enhancement of life in its manifold possibilities.

In line with a psychology more attached to the becoming [devenir] rather than tothe essence, the goal of this paper is to ground the importance of understandingsubjectivity as a process, mainly when regarding our current discussions aboutidentity and gender. After that, we do some linkage between art and psychology. Forus, art is understood as a powerfulmanner to encourage modes of subjectivation thathave difference as an inherited relation. Lastly, we draw our attention upon somefragments of the contemporaneous artist, Mathew Barney's work-of-art (specially,Cremaster), to see how it runs through the binaries of gender boundaries andlaunches post-identity lines of subjectivation.
