Aesthetic Education in the Early Years: Exploring Familiar and Unfamiliar Personal-Cultural Landscapes

This article explores a double-bind in early schooling: a persistent value placed upon presenting multicultural art forms to a child constructed as incapable of grasping what is not familiar. The author argues that this bind is situated within dominant developmental discourses that emphasize the appropriateness of concrete and sequential activities and within dominant school art discourses that have constructed early school art as ‘process over product’ and that have understood culture as heritage. Suggesting that all novices — adults and children — make meaning from complex cultural values intertwined with the arts in some similar ways, she presents a description of a personal encounter with a Japanese tea garden and ceremony in order to (a) explore notions of art, development, and school art as cultural sensibilities, and (b) illustrate a cyclical process of direct perception, personal-contextual meaning-making, and discursive analysis. She concludes by arguing that encounters with the unfamiliar present unrealized educative possibilities for aesthetic experience in early schooling and by discussing new directions for an aesthetic early childhood education

Porosity?permeability relationships in Miocene carbonate platforms and slopes seaward of the Great Barrier Reef, Australia (ODP Leg 194, Marion Plateau)

This paper reports a series of 700 porosity–permeability analyses and supporting petrographic and sedimentologic descriptions from Early to Late Miocene carbonate strata cored on the Marion Plateau, offshore from north‐eastern Australia, during Ocean Drilling Program (ODP) Leg 194. The samples analysed are not only mainly coarse bioclastic limestones and dolomitized equivalents from platform‐top facies, but also include 79 plugs from deeper‐water slope to hemipelagic drift facies. Outstanding characteristics of this data set are the wide ranges of porosity and permeability in both limestones and dolostones, the large degree of short‐range heterogeneity typical of these strata, and the better porosity–permeability correlation of dolostones than limestones. The platforms have experienced widely varying calcite cementation, dolomitization and dissolution but show little clear evidence of meteoric diagenesis, suggesting that subaerial exposure may have played little role in porosity–permeability evolution. Permeability‐for‐given‐porosity is controlled by grain size and calcite cement content in grainstones and by occurrence of larger shelter pores and vugs in mud‐rich samples. Dolomitization tends to reduce the variation of permeability‐for‐given‐porosity by recrystallizing mud matrix to form intercrystalline macroporosity that connects vugs and moulds to become integrated with the effective pore system. As a result, there are no differences in permeability–porosity trends for different dolostone textures, whether dominated by intercrystalline, vuggy, or preserved intergranular pore types. Two platform‐top sites separated by only 5 km display a major lateral variation in dolostone porosity–permeability characteristics within the youngest dolostone units. This difference is interpreted as reflecting a relatively ‘windward’ (current‐facing) setting of the site with the overall higher permeability‐for‐given‐porosity (Site 1199) that led to less muddy depositional facies, greater cementation, and lesser grain dissolution. Pore‐geometry parameters measured by petrographic image analysis confirm that the ‘windward’ dolostones have pores that are both larger and less intricate than dolostones comprising the more current‐protected location
