En este artículo se muestra cómo determinados aspectos del sistema uruguayo de educación secundaria pública inciden en rendimientos desiguales de los alumnos. Al utilizar la edición 2006 del Programa Internacional de Evaluación de Estudiantes (pisa) (ocde, 2006a) resaltan tres aspectos clave de las instituciones reguladoras de la educación secundaria que contribuyen a reproducir las desigualdades iniciales, inhibiendo el papel igualador que orienta al sistema educativo. En primer lugar, el mecanismo de asignación de docentes produce un doble efecto de alta rotación de profesores jóvenes en establecimientos de enseñanza de contextos socioculturales desfavorables, así como un anquilosamiento de aquellos docentes más experimentados en establecimientos de contextos favorables. En segundo lugar, el sistema de distribución de alumnos basado en el radio escolar reproduce tel proceso de segregación residencial existente. Finalmente, con el sistema centralizado de provisión de materiales educativos y tecnológicos no se logra cubrir las necesidades de los establecimientos.

This article shows how certain aspects at the secondary level of Uruguay’s public school system produce inequalities in student achievement. The 2006 edition of the Programme for International Student Assessment (pisa) (oecd, 2006a) points to three key aspects of the institutions that regulate secondary education that play a part in reproducing inequalities of origin, hindering the equalizing role that guides the education system. First, the teacher assignment mechanism has the dual effect of sending a revolving door of young and inexperienced teachers to schools in unfavourable sociocultural contexts as well as concentrating teachers with more experience in schools in favourable contexts. Second, the geography-based system for assigning students to schools reproduces the residential segregation process. Lastly, the centralized system for supplying educational and technological materials is inadequate to the needs of the schools.

The Virgo detector is a kilometer-scale interferometer for gravitational wave detection located near Pisa (Italy). About 13 months of data were accumulated during four science runs (VSR1, VSR2, VSR3 and VSR4) between May 2007 and September 2011, with increasing sensitivity. In this paper, the method used to reconstruct, in the range 10 Hz-10 kHz, the gravitational wave strain time series h(t) from the detector signals is described. The standard consistency checks of the reconstruction are discussed and used to estimate the systematic uncertainties of the h(t) signal as a function of frequency. Finally, an independent setup, the photon calibrator, is described and used to validate the reconstructed h(t) signal and the associated uncertainties. The systematic uncertainties of the h(t) time series are estimated to be 8% in amplitude. The uncertainty of the phase of h(t) is 50 mrad at 10 Hz with a frequency dependence following a delay of 8 mu s at high frequency. A bias lower than 4 mu s and depending on the sky direction of the GW is also present.

The Italian writer Antonio Tabucchi (Pisa-1943, Lisbon-2012) is considered by the critic as one of the most representative voices in the contemporary European literature. The Literature, according to Tabucchi, exerts a fundamental role in society and it, still according to the writer, must cause disquietude, evoke doubts, raise questions and not tranquilize people’s mind. Thereby, it’s noticed that it’s one of the reasons why the tabucchian narrative incessantly dialogues with Luigi Pirandello’s and Fernando Pessoa's poetics, establishing a great fictional game in wich the people, the truths, the history and the world are shown, at the least, duplicated.
