[Ressenya del llibre Convención y recepción : estudios sobre el teatro del Siglo de Oro, d’Ignacio Arellano]

Ressenya del llibre Convenció y recepción. Estudios sobre el teatro del Siglo de Oro, d’Ignacio Arellano . L’obra és, segons Ramos Nogales, el millor estudi de conjunt sobre la comèdia del Segle d’Or que ha aparegut en els últims anys així com una crida a la investigació tradicional

Didáctica de la LIJ y su aportación a un concepto intercultural de género

Quienes nos dedicamos a formar a futuros profesores a traves de la literatura, nos encontramos con el reto cada vez mas urgente de invitar a nuestros alumnos a revisar convenciones culturales sobre genero y raza. Algunas editoriales de literatura infantil estan realizando un serio esfuerzo en esta linea, aun asi, es necesario que profesores y maestros reconsideremos conceptos que asumimos sin cuestionarlos. El presente articulo pretende sugerir pautas metodologicas para llevar a cabo en el aula de magisterio

History and uses of music education for children who are hearing impaired

This paper discusses hearing impaired children and their ability to learn and enjoy music.

A description of characteristics of very young children referred for speech and language evaluation at Central Institute for the Deaf

This paper discusses the early identification and assessment of children younger than six who were referred to the Central Institute for the Deaf Speech and Hearing Clinic.

Deforming glassy polystyrene: Influence of pressure, thermal history, and deformation mode on yielding and hardening

The toughness of a polymer glass is determined by the interplay of yielding, strain softening, and strain hardening. Molecular-dynamics simulations of a typical polymer glass, atactic polystyrene, under the influence of active deformation have been carried out to enlighten these processes. It is observed that the dominant interaction for the yield peak is of interchain nature and for the strain hardening of intrachain nature. A connection is made with the microscopic cage-to-cage motion. It is found that the deformation does not lead to complete erasure of the thermal history but that differences persist at large length scales. Also we find that the strain-hardening modulus increases with increasing external pressure. This new observation cannot be explained by current theories such as the one based on the entanglement picture and the inclusion of this effect will lead to an improvement in constitutive modeling.

Joint effects of density and a growth inhibitor on the life history and population growth rate of the midge Chironomus riparius

Results of previous laboratory studies suggest that high population density often buffers the effects of chemical stressors that predominately increase mortality. Mortality stressors act to release more resources for the survivors and, therefore, produce less-than-additive effects. By contrast, growth stressors are expected to have opposite results or more-than-additive effects. We investigated the effects of a growth inhibitor (lufenuron) on larval growth and survival of Chironomus riparius and examined its joint effects with density on population growth rate (PGR). Exposure to 60 mu g/kg sediment or greater inhibited larval growth, and exposure to 88 mu g/kg or greater often resulted in mortality before reaching emergence. The effects of lufenuron, however, differed with population density. At 88 mu g/kg, mortalities and, to a lesser extent, reduced fecundity resulted in a reduction in PGR at low density. Conversely, when populations were initiated at high density, PGR was similar to that of controls, because the few survivors reached maturity sooner and started producing offspring earlier. The effect of density as a growth stressor therefore was stronger than the effect of lufenuron, which had effects similar to those of a mortality stressor and produced less-than-additive effects. Longterm studies under field conditions, however, are needed before less-than-additive effects are considered to be the norm.
