We introduce the Profinite Hull functor of special groups, showing that it gives rise to a new local - global principle, the subform reflection property. We also indicate applications of this principle to the abstract algebraic theory of quadratic forms.

En el texto se hace hincapié en los tenebrosos elementos sacrificiales que le ha acarreado al movimiento estudiantil perteneciente a la combativa Escuela Normal Rural de Ayotzinapa, situada en el Estado mexicano de Guerrero, dominado por el narcotráfico y un gobierno municipal que actúa en complicidad con este último. Se trata de un establecimiento que, además de formar maestros populares, se halla enrolado en las luchas sociales y políticas. A fines de 2014 fueron reprimidos brutalmente y objeto de desaparición forzosa (...) unos 43 alumnos de esa Escuela, lo cual dio lugar a una ininterrumpida protesta civil con muy diversos ribetes internos y mundiales cuyas múltiples expresiones procuran explicitarse en el trabajo. Por otra parte, se incursiona en el trasfondo ideológico que viene acompañando el devenir institucional mexicano bajo el manto del neoliberalismo -al cual el autor ha optado por reconceptuar como neuroliberalismo en distintos ensayos suyos y en colaboración. Conjuntamente, se enfoca la problemática en cuestión desde un ángulo doctrinario y existencial específico: el del necropoder y el pensamiento crítico. Entre los referentes bibliográficos principales pueden citarse desde Foucault y Mbembe a Holloway y González Casanova. The paper deals with the engagement of mexican student movement in Ayotzinapa Rural College and the repressive way that the local goverment and the narco-maffia fought against those students, with the disappearance and destruction of their bodies and cadavers, around september 2014. The case has an enormous influence in world and local public opinion, with different movilizations and artistic expressions that have a very critical reading of Mexican treatment in the field of Human Rights. Mexican and international neoliberalism, as well as bio and necropolitics, has been specially analyzed with the auxiliary tool of critical thinking. Between the theoretical authors that are close involved in these approaches, we can find Michel Foucault, Achille Mbembe, John Holloway and Pablo González Casanova. (shrink)

Book reviewed in this article: Mental Disabilities and Criminal Responsibility. By Herbert Fingarette and Ann Fingarette Hasse.

The study of agriculture in ancient societies is of vital importance for the understanding of their ecological basis. This article discusses data gathered from Alonso de Molina's dictionary, published in Mexico City in 1571. Molina's information on soil, rain, plants, technology, and human labor applied to agricultural activities gives a picture of the complexity of the several native agricultural systems practiced at that time. Since the Sixteenth Century, native agriculture was impacted by the introduction of new plants, animals, agricultural equipment, (...) and techniques from the Old World. A combination of the two agricultural models conform a new Mexican model of agriculture along the Colonial times. The knowledge of Sixteenth Century agricultural systems is fundamental for the understanding of the history and the conformation of contemporary agro-ecosystems. Recent studies on ecology and social anthropology agree on the necessity to take into account historical data for the discussion of ecological sustainability. (shrink)

En un libro reciente, Maurizio Viroli sostiene que en El Príncipe Maquiavelo delinea la imagen del fundador que la teoría política republicana necesita, la que recibe su encarnación paradigmática en Moisés y sus acciones. Aquí propongo que para una comprensión adecuada del Moisés de Maquiavelo resulta clave la interpretación que éste ofrece del incidente del becerro de oro (Discursos III, 30), al que interpreta como una revuelta contra Moisés motivada por la envidia. Este episodio, sugiero, ejemplifica las acciones necesarias para (...) asegurar las instituciones de un estado libre recién constituido en el contexto del conflicto permanente entre grandes y pueblo.
