Diabatic Forcing

Abstract. The quasigeostrophic theory is used to address the role of diabatic forcing in synoptic scale processes over Iberia. A parametrization of diabatic heating is obtained in terms of a thermodynamic variable called the ice-liquid water potential temperature which is conservative under all phase changes of water. A case study objectively selected by means of a rotated principal component analysis over the diabatic field is analyzed to test the proposed parametrization. This study highlights the fact that the magnitudes of diabatic forcing and dynamic forcing are very nearly the same throughout the troposphere. The results also show that the composite diabatic heating is a better representation for both cloudiness and precipitation fields than the dynamic forcing.

The island marble butterfly (Euchloe ausonides insulanus), thought to be extinct throughout the 20th century until re-discovered on a single remote island in Puget Sound in 1998, has become the focus of a concerted protection effort to prevent its extinction. However, efforts to “restore” island marble habitat conflict with efforts to “restore” the prairie ecosystem where it lives, because of the butterfly’s use of a non-native “weedy” host plant. Through a case study of the island marble project, we examine the practice of ecological restoration as the enactment of particular norms that define which species are understood to belong in the place being restored. We contextualize this case study within ongoing debates over the value of “native” species, indicative of deep-seated uncertainties and anxieties about the role of human intervention to alter or manage landscapes and ecosystems, in the time commonly described as the “Anthropocene.” We interpret the question of “what plants and animals belong in a particular place?” as not a question of scientific truth, but a value-laden construct of environmental management in practice, and we argue for deeper reflexivity on the part of environmental scientists and managers about the social values that inform ecological restoration.

Abstract In the following article we try to re-evaluate, the place drama occupies in contemporary elementary education. By limiting the role of drama to literature studies and theatre productions, we lose a greater potential Theatre Pedagogy has to offer to a much broader educational spectrum. The participatory practices of Theatre and Drama in Education (TiE, DiE) promote active learning, based on a most organic children’s activity - play. While students co-create the fictional world of drama, teacher's guidance is crucial in setting new challenges, encouraging students to find creative solutions and reflect on often-complex social issues. Because of its art component, drama challenges the participants on a cognitive as well as emotional level, becoming a truly transformational experience. As such, Drama in Education is especially useful when approaching sensitive and controversial topics. This thesis is presented on a case study observing Year 6 students at St’ Michael’s CE Academy in Birmingham, UK, using Drama in Education method as part of History curriculum.
