Análisis de los impactos del uso del teléfono móvil en los estilos de vida [ocio y tiempo libre, relaciones sociales, y conductas sedentarias] de los adolescentes en enseñanza secundaria obligatoria de la Comunidad Autónoma de Aragón, España

La presente investigación tuvo como objetivo analizar los impactos del uso del teléfono móvil en los estilos de vida (ocio y tiempo libre, relaciones sociales, y conductas sedentarias) de los adolescentes en enseñanza secundaria obligatoria de la comunidad autónoma de Aragón (España). Comenzamos por revisar conceptualizaciones, revisamos acerca del bienestar y de los hábitos de vida de los adolescentes, el teléfono móvil y sus implicancias para la salud y estilos de vida, sus usos y representationes. Metodológicamente, se trata de un estudio descriptivo y cuantitativo. Realizamos un análisis exploratorio de los datos, y complementariamente testeamos la relación entre variables. En conclusión, podemos afirmar que los adolescentes en Aragón: Tienen una visión positiva de su salud; Entre las conductas sedentarias asociadas a las pantallas, prevalece el uso del teléfono móvil en el fin de semana; La seguridad es la función referencial (valor simbólico) más valorizada del teléfono móvil; Poder comunicarse con los amigos, es la principal razón para querer tener su primer teléfono móvil; Enviar o recibir mensajes de los amigos/as, es la función comunicativa (valor instrumental) más valorizada del teléfono móvil; Escuchar música o la radio, es el mayor uso de la función lúdico-expresiva-organizativa (valor instrumental) del teléfono móvil.

‘You, my body, and my mind, one of these will go’: Madness as Disguise in Samuel Beckett's Murphy and Endgame

ithin the wide topic of disguise in literature, we could signal a subcurrent which can be found in a number of literary texts: the idea of madness as a disguise, i.e. the creation or invention of a ‘false self’ as a mask which is presented to the world and which conceals the real self. In The Divided Self (1960), R. D. Laing deals with the “personality, false self, mask, front or persona that (...) [schizophrenic] wear” (73). Using as a basis Laing’s theories on schizophrenia and the creation of a false-self system, we will analyze two works by Samuel Beckett: Murphy and Endgame, where we find the uses of madness as disguise in a series of ways: through the usage of ‘disguised’ language (what we could refer to as schizophrenese) which acts as a mask for real meaning; through odd ‘schizophrenic’ behaviour on the part of the characters (which screens real intentions), and, mainly, through the creation of a ‘false self’ which acts as a disguise and barrier between the inner self and the real world. These two works by Samuel Beckett, where real intentions and meanings are continuously concealed and disguised in a desperate attempt to preserve the inner self, lend themselves to an analysis of madness as disguise, precisely the one we attempt to carry out in our paper.

Abstraction and use of groundwater for heating buildings in a hard rock environment

In order to turn more efficient the heating of class rooms in the lower floor of the old building of the University of Évora (a XVI century building), five drillings were organised inside the area of the university (Figure 1). The purpose was to use the temperature differential of groundwater in relation to air, by means of a heat exchanger, and use this process to heat the rooms using less energy, turning the heating process less expensive. The wells were drilled in fractured rocks (gneisses), and the purpose was to locate them at least around 100 m one from each other, whilst trying to have a hydraulic connection in-between. From the five initial wells, four were successful in terms of productivity, but just two of them (RA1 and RA2) proved to be hydraulically connected. The wells were equipped with screens for all their drilled depth (100 m), except for the first six meters and some two or three pipes of six meters each, to allow space for the installation for submersible pumps. The length of the installed screens guarantees a good efficiency of the system. In the wells with no connection, the heating system can work using each single well for abstraction and injection, but the process is much less efficient than in the cases where interaction between wells is possible through the rock’s fracture network.
