Formalizing defeasible argumentation using a labeled deductive system

In the last years there has been an increasing demand of a variety of logical systems, prompted mostly by applications of logic in AI, logic programming and other related areas. Labeled Deductive Systems (LDS) were developed as a flexible methodology to formalize such a kind of complex logical systems. In the last decade, defeasible argumentation has proven to be a confluence point for many approaches to formalizing commonsense reasoning. Different formalisms have been developed, many of them sharing common features. This paper presents a formalization of an LDS for defensible argumentation, in which the main issues concerning defeasible argumentation are captured within a unified logical framework. The proposed framework is defined in two stages. First, defeasible inference will be formalized by characterizing an argumentative LDS. That system will be then extended in order to capture conflict among arguments using a dialectical approach. We also present some logical properties emerging from the proposed framework, discussing also its semantical characterization.

Ocio y recreación.

El objetivo fundamental del proyecto es llenar el vacío existente en los currículos oficiales en cuanto al escaso tiempo dedicado a la Educación Física, ocupación del tiempo libre, ocio, y animación sociocultural. Se plantean, además, como objetivos específicos: ofrecer al alumno la posibilidad de completar su formación por medio de actividades ocio-recreativas; posibilitar la práctica de deportes al aire libre tanto individuales como grupales relacionados con el conocimiento del medio ambiente; favorecer la participación en deportes reglados y competiciones; y dotar al alumnado de los conocimientos y técnicas adecuadas para organizar su preparación física. De las dos modalidades que se proponen para su puesta en marcha, se elige la de asignatura voluntaria, dados los problemas que presenta su constitución en EATP. La experiencia consiste por una parte en el trabajo en el seminario centrado en la teoría de sistemas de entrenamiento, utilizando el ordenador para el control de éstos, conocimiento de los recursos disponibles, introducción a la cartografía y orientación, y preparación de marchas y actividades; y por otra, en la práctica de deportes como: natación, tenis, baloncesto, frisbee, badminton, patinaje, cicloturismo, marchas de orientación, participación en las Jornadas de mujer y deporte, y semana blanca.

Experimental gestational hypothyroidism evokes hypertension in adult offspring rats

Gestational hypothyroidism is a prevalent disorder in pregnant women. We aimed to investigate the impact of experimental gestational hypothyroidism (EGH) on cardiovascular and autonomic nervous systems (ANS) in the offspring of rats. EGH was induced with methimazole (MMI) 0.02% in drinking water from day 9 of gestation until birth. Sixty day old offspring from MMI-treated dams (OMTD, n = 13) or water-treated dams (OWTD, n = 13) had femoral arteries surgically assessed for the measurements of heart rate (HR), mean (MAP), systolic (SAP) and diastolic arterial pressure (DAP), and spontaneous baroreflex sensitivity (BRS). To investigate the balance of ANS, we established the high (HF) and low frequency (LF) bands of pulse interval (PI) and LF band of SAP spectrum. OMTD had increased MAP (130.2 +/- 2.0 vs 108.8 +/- 3.0 mm Hg, p<0.001), SAP (157.3 +/- 2.9 vs 135.7 +/- 4.5 mm Hg, p<0.001) and DAP (109.7 +/- 1.9 vs 88.4 +/- 2.6 mm Hg, p<0.001) when compared to OWED, and had lower HR (355.1 +/- 8.9 vs 386.8 +/- 9.2 bpm, p<0.05). After spectral analysis of PI and SAP, only LF band of SAP spectrum was higher (7.2 +/- 0.8 vs 4.0 +/- 0.6 mm Hg-2, p<0.01) in OMTD under spontaneous condition. Despite bradycardia, EGH promotes spontaneous hypertension in 60 day old offspring, probably due to increased sympathetic modulation of vessels, which is suggested by the higher LF of SAP. These findings suggest a critical role of maternal THs in the development of fetal cardiovascular and autonomic nervous systems. Crown Copyright (C) 2012 Published by Elsevier B.V.

La movilidad como solución

Las organizaciones internacionales, las ONG e incluso los investigadores tienden a tachar de “refugiados” a todos los sirios que hoy se encuentran en sus países vecinos. Aunque esta definición pudiera reflejar la categoría administrativa de los registrados por ACNUR, no supone un reflejo fiel del diverso abanico de realidades donde viven. No todos los que se han marchado a países vecinos de Siria se encuentran registrados ni tampoco se consideran a sí mismos refugiados.
